FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with deafness is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about deafness, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to deafness, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on deafness. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to deafness, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on deafness. The Editors

CHAPTER 1. STUDIES ON DEAFNESS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on deafness.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and deafness, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “deafness” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Death of Deafness? The Choice to Hear: Setting the Baseline Source: Hearing Health. 16(3): 54-57. May-June 2000. Contact: Available from Voice International Publications, Inc. P.O. Drawer V, Ingleside, TX 78362-0500. Voice/TTY (361) 776-7240. Fax (361) 776-3278. Website: www.hearinghealthmag.com. Summary: Anecdotal evidence from the hearing health care field indicates that the vast majority of new parents with deaf babies favor technological intervention which enables their babies to hear. This article, the first in a series on the death of deafness, reviews the statistics that support this apparent trend. The author outlines the problem of defining and quantifying the number of Americans who are deaf, then discusses the sources of his data, the use of probability analysis, the impact of new technology on the Deaf

culture, input from other sources, the demographics of deafness, and public policy issues. The author concludes by describing recent programs designed to maximize early identification of hearing loss. The author stresses that the most urgent task is to find all deaf babies at birth and provide them with the hearing aids, cochlear implants, or schooling in sign language they need; identifying infants and children who lose their hearing after birth is also crucial. Further research on the economic effects of deafness is called for. The contact information for two resource organizations (The National Campaign for Hearing Health and Project Hope Center for Health Affairs) is provided. 3 figures. •
Mediated Communication in the Postsecondary Education of Deaf Students Source: JADARA. Journal of the American Deafness and Rehabilitation Association. 30(1): 1-8. 1996. Summary: As increasing numbers of students with impaired hearing seek postsecondary education, the naivete of many postsecondary institutions about these students' needs assumes greater importance. Students report and staff confirm that representative facilities often fail to distinguish between students who are deaf and students who hard of hearing. Such confusion leads to inappropriate accommodations, when any are made. This article considers the use of mediated communication in the postsecondary education of students who are deaf. The authors suggest antidotes for the neglect and confusion, and offer ideas for alterations in educational administration, for preparing and deploying interpreters, and for research. 1 table. 36 references.

[email protected]. Website: www.ajkd.org. Summary: Branchio oto renal (BOR) syndrome is a rare autosomal dominant condition that may present with hearing loss, branchial cysts, and renal failure. The characteristic phenotypic expression of the full syndrome may be partial or complete, and a whole range of renal (kidney) abnormalities may be present. The similarity of BOR to Alport's syndrome may lead to misdiagnosis. This article presents a case report of adult onset renal failure in a 44 year old white man with deafness, previously believed to have Alport's syndrome. The patient's hearing loss was believed to be congenital, and he was prescribed hearing aids. By the age of 19 years, deafness had worsened significantly, and a diagnosis of bilateral moderately severe mixed hearing loss was made. The authors review the relevant literature. The authors note that it is not clear why there is an association between renal malformation and abnormalities of the ear. 2 figures. 18 references.

enculturated into the Deaf world. Deaf culture has its own history, values, traditions, folklore, and communication behaviors. Its language is American Sign Language (ASL), which gives the culturally Deaf group its identity. This article provides an overview of Deaf culture; its unique behavioral characteristics, values, and traditions; and suggestions for ways to improve interaction between Deaf people and communication professionals. The author stresses that people who are culturally Deaf do not consider deafness a pathology or abnormality. They view themselves as a cultural minority. Even though speech is not compatible with ASL, culturally Deaf people may be interested in spoken English because they realize they must interact with hearing people. The author emphasizes that audiology and speech-language pathology professionals should acknowledge and respect Deaf culture in order for training in English communication to be successful. Deaf people are responsive to professionals who are interested in helping them gain access to the same rights and privileges that hearing people enjoy. 40 references. (AA-M). •
Empowering the Deaf. Let the Deaf Be Deaf Source: Journal of Epidemiology and Community Health. 54(1): 40-44. January 2000. Contact: Available from BMJ Publishing Group. P.O. Box 590A, Kennebunkport, ME 04046. (800) 236-6265. Summary: Deafness is often regarded as a singular phenomenon of homogeneous quality. The medical viewpoint usually classifies deafness by pathology attributable to an inner ear disorder are segregated from pathologies attributable to an outer or middle ear disorder. In this article, the authors argue that hearing loss is a very complex phenomenon which has many and serious consequences for the person with hearing loss. Medical intervention has tended to be concerned more with the origin, degree, type of loss, onset, and structural pathology of deafness than with communicative disability and the implications there may be for the patient. These implications include dependency, denial of abnormal hearing behavior, low self esteem, rejection of the prosthetic help, and the breakdown of social relationships. The authors stress that empowering strategies, aimed at promoting not only a more traditional psychological empowerment but also a community one, should primarily focus on the removal of communication barriers. The authors offer specific strategies on enhancing legislation regarding communication barriers, providing the necessary information, improving the health care setting, and improving patient-physician communication. 42 references.

Sexuality and Deafness. A Call for Education Source: Hearing Health. 14(4): 30-32. July-August 1998. Contact: Available from Voice International Publications, Inc. P.O. Drawer V, Ingleside, TX 78362-0500. Voice/TTY (361) 776-7240. Fax (361) 776-3278. Website: www.hearinghealthmag.com. Summary: Limited access to sexuality information puts children who are deaf or hard of hearing at risk for sexual abuse. This article discusses this issue and proposes a greater emphasis on sex education for these children. The author notes that, because a majority of children who are deaf are born to hearing parents who do not develop effective communication tools, they do not receive sexual education within the home. Barriers to communication in the outside world and poor reading levels further complicate the situation. Unlike their hearing peers, these children often miss information that is obtained vicariously. They do not have the same access to conversations, radio, television, or written sources. The author contends that schools can help bridge the gap by providing accessible information. Sexuality education can potentially reduce the risk of sexual abuse by providing information about behaviors that are appropriate or inappropriate; assistance in establishing boundaries regarding the body; vocabulary enabling children to recount their experiences; and skills for developing positive, appropriate relationships. Once children understand these points, they may be less likely to experience sexual abuse. (AA-M).

Maternally Inherited Diabetes and Deafness: A Multicenter Study Source: Annals of Internal Medicine. 134(9 Part 1): 721-728. May 1, 2001. Contact: Available from American College of Physicians-American Society of Internal Medicine. 190 North Independence Mall West, Philadelphia, PA 19106-1572. Summary: Maternally inherited diabetes and deafness (MIDD), which is seen in 0.5 percent to 2.8 percent of patients with type 2 diabetes mellitus, is related to a point mutation at position 3243 of mitochondrial (mt) DNA. The clinical description of MIDD is incomplete. This article reports on a study of the clinical presentation and complications of diabetes in patients with MIDD, undertaken to identify clinical characteristics that may help select patients with diabetes for mtDNA mutation screening. The study included 54 patients with type 2 diabetes mellitus and the mtDNA 3243 mutation, from 16 French departments of internal medicine, diabetes, and metabolic diseases. On average, patients with MIDD were young at diabetes onset and presented with a normal or low body mass index. None were obese; 73 percent of subjects had a maternal family history of diabetes. Diabetes was non insulin dependent at onset in 87 percent of patients; however, 46 percent of patients had non insulin dependent disease at onset but progressed to insulin therapy after a mean duration of approximately 10 years. Neurosensory hearing loss was present in almost all patients. Of the patients who received an ophthalmologic examination, 86 percent had macular

pattern dystrophy (a specific retinal lesion). Myopathy (muscle weakness and wasting) was found in 43 percent of patients, 15 percent had cardiomyopathy (wasting and weakness of the heart muscles), and 18 percent (9 of 51 patients) had neuropsychiatric symptoms. The prevalence of diabetic retinopathy (eye disease) was 8 percent among patients who received an ophthalmologic examination, lower than expected after a mean 12 year duration of diabetes; prevalence of kidney disease was 28 percent. This suggests that a specific renal involvement was the result of mitochondrial disease. The authors conclude that MIDD has a specific clinical profile that may help identify patients with diabetes who should undergo mtDNA testing. 2 figures. 1 table. 46 references. •

[email protected]. Summary: Most medical school curricula and major textbooks characterize deafness as a pathologic condition only, which is at odds with the movement to understand the Deaf population as a minority group with a unique language and cultural tradition. Physicians might therefore be unprepared to meet the needs of deaf patients effectively and sensitively. This article reports on a study that investigated the health care experiences of elderly Deaf adults in Richmond, Virginia. The authors conducted focus groups of elderly Deaf persons. Real time voice interpretation of the sign language communication allowed for tape recording and full transcription. Results showed that participants experienced many practical barriers to effective health care, including problems with scheduling appointments and communicating with providers. They believed that providers are ill prepared to care for them and worried that prejudice might be a more subtle obstacle. Participants seemed resigned to these circumstances. The authors suggest a possible explanation for this perspective, and make specific recommendations for three levels of competency in caring for deaf patients. The authors conclude that when the provider and the office staff provide methods to communicate with deaf patients using telephone assisted communication, qualified interpreters, and some basic knowledge of lipreading or sign language, the care of deaf patients is greatly enhanced by the physician patient relationship. 29 references.

Sudden Total Bilateral Deafness Due to Asymptomatic Mumps Infection Source: International Journal of Pediatric Otorhinolaryngology. 45(2): 167-169. October 1998. Contact: Available from Elsevier Science. P.O. Box 945, New York, NY 10159-0945. (888) 437-4636. Fax (212) 633-3680. E-mail:
[email protected]. Summary: Mumps is the most common cause of unilateral (one side) acquired sensorineural hearing loss in children. Although it usually affects the salivary glands, the inner ear may be involved. Deafness is usually unilateral, sudden in onset, profound, and permanent. Bilateral total sensorineural hearing loss has rarely been reported in the English literature. This article presents a case of total deafness due to asymptomatic mumps infection. The 4 year old girl presented with a 10 day history of not answering to the parents sound stimuli. The parents had not noticed parotid swelling or tenderness, vertigo, nausea or meningeal signs, but marked a mild fever and fatigue before the event. The authors report the diagnostic tests used with the child, and

notes that she was given the standard sudden sensorineural hearing loss regimen of immunosuppressive agents. Hearing loss did not resolve on this regimen after a week, and the drugs were discontinued. The authors conclude by hypothesizing that sudden hearing loss develops with an immune mediated reaction after a viral induction (except some clear traumatic etiologies, for example). The hearing aid was ineffective in this patient, and a rehabilitation therapy was introduced. There was no improvement 3 months later and she was accepted as a candidate for cochlear implantation. 2 tables. 12 references. •
Carrier Rates in the Midwestern United States for the GJB2 Mutations Causing Inherited Deafness Source: JAMA. Journal of the American Medical Association. 281(23): 2211-2216. June 16, 1999. Summary: Mutations in the GJB2 gene are the most common known cause of inherited congenital severe-to-profound deafness. The carrier frequency of these mutations is not known. This article reports on a study undertaken to determine the carrier rate of deafness causing mutations in GJB2 in the midwestern U.S. and the prevalence of these mutations in persons with congenital sensorineural hearing loss ranging in severity from moderate to profound, and to derive revised data for counseling purposes. The study included 52 subjects younger than 19 years, sequentially referred to a midwestern tertiary referral center for hearing loss or cochlear implantation, with moderate to profound congenital hearing loss of unknown cause, parent nonconsanguinity, and nonsyndromic deafness with hearing loss limited to a single generation; 560 control neonates were screened for the 35delG mutation. Of 52 sequential probands referred for congenital sensorineural hearing loss, 22 (42 percent) were found to have GJB2 mutations. The 35delG mutation was identified in 29 of the 41 mutant alleles. Of probands sib, all homozygotes and compound heterozygotes had deafness. Fourteen of 560 controls were 35delG heterozygotes, for a carrier rate expressed as a mean of 2.5 percent. The carrier rate for all recessive deafness causing GJB2 mutations was determined to be 3.01 percent. The authors conclude that this data suggests that mutations in GJB2 are the leading cause of moderate to profound congenital inherited deafness in the midwestern U.S. Screening of the GJB2 mutation can be offered to individuals with congenital deafness with high sensitivity and specificity by screening only for the 35delG mutation. A positive finding should establish an etiologic diagnosis and affect genetic counseling.

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. (800) 654-2452. Summary: Pediatricians, as part of an interdisciplinary team, can provide families of children with hearing loss or deafness with information about important resources to expedite their child's habilitative process. This article, from a monograph on hearing loss in children, describes the emotional stages that parents and caregivers may experience upon initial diagnosis of hearing loss and the support that pediatricians can offer during this critical time of discovery when families seek guidance. The authors discuss the variety of communication strategies and options available to children and families, based on the child's specific needs, diagnostic findings, educational opportunities, family culture, and preferences.

Self-Report of Cochlear Implant Use and Satisfaction by Prelingually Deafened Adults Source: Ear and Hearing. 17(3): 198-210. June 1996. Summary: Prelingually deafened adults tend to demonstrate smaller improvements in speech recognition after cochlear implantation than do post-lingually deafened adults. This article reports on a study undertaken to evaluate cochlear implant use and satisfaction by prelingually deafened adults. A questionnaire was administered to 12 prelingually deafened adult cochlear implant patients to evaluate cochlear implant efficacy and satisfaction Questionnaire results were contrasted with performance on speech recognition tasks. Results showed that although these patients demonstrated little or no improvements in speech recognition 12 months postoperatively, most patients reported that they used their device regularly, that they were satisfied with their device, and that using the cochlear implant improved both their expressive and receptive communication skills. The authors conclude that procedures other than traditional speech recognition measures should be used to evaluate cochlear implant benefit, particularly with prelingually deafened adults.

Role of Educators of the Deaf in the Early Identification of Hearing Loss Source: American Annals of the Deaf. 144(1): 19-23. March 1999. Contact: Available from American Annals of the Deaf. KDES PAS-6, 800 Florida Avenue, NE, Washington, DC 20002-3695. Summary: Professionals in deaf education, as well as deaf and hard of hearing individuals, play an important role in the development of comprehensive systems of care for deaf and hard of hearing infants and young children. Universal newborn hearing screening programs typically are linked to health systems rather than educational systems. This article explores the need for new links between health and education services in order for educators of deaf and hard of hearing children to be involved in early identification and intervention programs. Identification of hearing loss in infancy, followed by appropriate intervention by age 6 months, can result in normal language development, regardless of degree of hearing loss. As the average age of identification of hearing loss moves downward toward 2 months, children with hearing loss will enter the educational system earlier and with language skills commensurate with those of their hearing peers. Early interventionists will need to have specialized training in deafness and hearing loss, and to have expertise in providing services to very young children and to children with hearing loss in the broad range from mild to profound. One section of the article discusses the early identification and intervention strategies in place at the Marion Downs National Center for Infant Hearing, a center for the promotion of programs for screening, diagnosis, and intervention for newborns and infants who are deaf or hard of hearing. 1 table. 20 references.

[email protected]. Summary: Reading builds fundamentally on primary language processes. For hearing readers, this means that spoken language processes, including phonological processes, are critical to high achievement in reading. In this article, the authors examine the implications of this fact for deaf readers by considering the relationship between language and reading and by reviewing the research on the use of phonology by deaf readers. The research, although mixed in its results, suggests that the use of phonology is associated with higher levels of reading skills among deaf readers. The authors examine related questions, including the additional semantic and visual strategies available to deaf readers, how some deaf readers gain access to the spoken structure of language, and implications for how to improve reading achievement. 65 references. •

[email protected]. Summary: Recent advances within molecular genetics to identify the genes for deafness mean that it is now possible for genetic counseling services to offer genetic testing for deafness to certain families. This article reports on a study undertaken to document the attitudes of deaf adults toward genetic testing for deafness. A structured, selfcompletion questionnaire was given to delegates at an international conference on the Deaf Nation held at the University of Central Lancashire (United Kingdom), in 1997. Eighty-seven deaf delegates from the UK returned completed questionnaires. The questionnaire was designed to quantitatively assess attitudes toward genetics, interest in prenatal diagnosis (PND) for deafness, and preference for having deaf or hearing children. The results from this study demonstrate evidence of a predominantly negative attitude toward genetics and its impact on people who are deaf, in a population for whom genetic counseling services are relevant. Fifty-five percent of the sample thought that genetic testing would do more harm than good, 46 percent thought that its potential use devalued deaf people, and 49 percent were concerned about new discoveries in genetics. When asked about testing in pregnancy, 16 percent of participants said that they would consider having PND, and, of these, 29 percent said that they would prefer to have deaf children. The authors note that geneticists need to appreciate that some deaf persons may prefer to have deaf children and may consider the use of genetic technology to achieve this. Any genetic counseling service set up for families with deafness can only be effective and appropriate if clinicians and counselors take into consideration the beliefs and values of the deaf community at large. 5 figures. 18 references.

Summary: Severe hearing impairment is seldom detected in children before the age of 6 to 12 months, because parent infant interaction at that stage resembles hearing parent child interaction. This is probably due to an innate capacity of infants to take information in one sensory modality and translate it into another, called amodal perception. This article traces the development of communication and language in children who are deaf or severely hard of hearing. The author traces the roots of language to early protoconversations, as well as to early pretend play. Relationships are viewed as the context in which socialization takes place, basic competencies emerge, regulations of emotions develop, and communication skills are acquired. If habilitation after diagnosis of a severe hearing impairment primarily is focused on an oral aural approach, natural patterns of communication between parent and child will gradually disappear, which will have negative implications on the development of these children. If, instead, they are allowed to develop those means of communication that are easy for them to produce and to perceive, positive consequences have been registered on the development of communication and language, as well as on their socioemotional and cognitive development. When these children have been given opportunities to become bilingual with a signed, written, or spoken language, it has improved their overall quality of life. 17 references. •

[email protected]. Summary: Since the very beginning of formal approaches to deaf education, the development of literacy has been a priority issue. The history of educational initiatives in this area is entwined with the history of prevailing attitudes and practices toward the impact of deafness on the development of deaf children more generally. In particular, arguments about whether a visual input (reading) can take the place of a diminished auditory input and whether educators should accommodate or seek to ameliorate the effects of the special linguistic characteristics of deaf learner readers have resulted in a wide variety of practices and perspectives. These varied practices and perspectives continue to have impacts on current educational debate and practice. This article provides a brief historical overview of these educational endeavors and the authors note the enduring questions and issues that remain for the field to address. 32 references.

Individual Differences in Effectiveness of Cochlear Implants in Children Who Are Prelingually Deaf: New Process Measures of Performance Source: Volta Review. 101(3): 111-164. Summer 1999. Contact: Available from Alexander Graham Bell Association for the Deaf and Hard of Hearing. Subscription Department, 3417 Volta Place, NW, Washington, DC 20007-2778. Voice/TTY (202) 337-5220. Website: www.agbell.org. Summary: The efficacy of cochlear implants in children who are deaf has been firmly established in the literature. However, the effectiveness of cochlear implants varies widely and is influenced by demographic and experiential factors. This article reports on new process measures of performance that are being used to measure these individual differences in effectiveness of cochlear implants in children. Several key findings suggest new directions for research on central auditory factors that underlie the effectiveness of cochlear implants. First, individual differences have been observed in both adults and children on a wide range of audiological outcome measures. Some patients show large increases in speech perception scores after implantation, whereas others display only modest gains on standardized tests. Second, age of implantation and length of deafness affect all outcome measures. Children implanted at younger ages do better than children implanted at older ages, and children who have been deaf for shorter periods do better than children who have been deaf for longer periods. Third, communication mode affects outcome measures (i.e., children from oral only environments do better than children who use Total Communication). Fourth, there are no preimplant predictors of outcome performance in young children. Finally, there are no significant differences in audiological outcome measures among current implant devices or processing strategies. Taken together, this overall pattern of results suggests that higher level central processes such as perception, attention, learning, and memory may play important roles in explaining the large individual differences observed among users of cochlear implants. 10 figures. 6 tables. 69 references.

[email protected]. Website: www.angelfire.com/il/freund. Summary: The existence of subclinical signs in the hearing of carriers of recessive mutations for deafness has aroused much controversy in the literature. This article reports on a study that comprised 30 carriers of recessive mutations for deafness, and a control group of 30 healthy volunteers, matched for gender and age. All participants underwent a series of hearing tests, including pure tone audiometry, speech tests, Bekesy audiometry and notch noise tests. The main results were: hearing loss in high frequencies (3000 and 4000 Hz), an elevation of the acoustic reflex threshold, as well as an elevation of the identification of 2000 Hz pure tone in the presence of white noise and notch noise. A notch in the Bekesy audiogram was also identified in several carriers. An interaction was found at 4000 Hz, and in the ipsilateral and contralateral acoustic reflex at 500 Hz and 1000Hz. Gender differences were found in pure tone as well as the acoustic reflex tests. This study suggests that the carrier state of autosomal recessive deafness might be identifiable by simple audiological tests. However, routine clinical use of these methods should be deferred until further studies confirm the results and technical improvements provide better differentiation between groups. The authors

conclude that these subclinical signs may be complementary to DNA research in the investigation of genetic deafness of unknown origin. 1 table. 16 references. •
Hearing Improvement After Therapy for Hyperlipidemia in Patients with ChronicPhase Sudden Deafness Source: Annals of Otology, Rhinology and Laryngology. 110(2): 105-108. February 2001. Contact: Available from Annals Publishing Company. 4507 Laclede Avenue, St. Louis, MO 63108. Summary: The hearing of patients with chronic phase sudden deafness and associated hyperlipidemia (high levels of fats in the blood) tends to improve with therapy for the hyperlipidemia. This article reports on a study of 12 patients with unilateral sudden deafness and hyperlipidemia in whom more than 1 month had elapsed since the onset of the hearing disturbance. The disturbance was considered to be irreversible without therapy. The 4 men and 8 women ranged in age from 32 to 73 years, with a mean age of 54.3 years. Hyperlipidemia was diagnosed when the total blood cholesterol level was 230 mg per dL or greater. The therapy for hyperlipidemia consisted of diet therapy and the administration of antilipemic drugs. The hearing level was measured both before therapy and when the total blood cholesterol level had decreased to less than 230 mg per dL. After therapy, the mean hearing level had improved significantly at each of 125, 250, 500, and 2,000 Hertz (Hz), but the changes in the level were not significant at 1,000, 4,000, or 8,000 Hz. The authors conclude that with therapy for hyperlipidemia, hearing tends to improve in patients with chronic phase sudden deafness and associated hyperlipidemia, even when more than 1 month has elapsed since the onset of the presumably otherwise irreversible hearing loss. 3 figures. 1 table. 8 references.

Smoking and Deaf Adults: Associations with Age at Onset of Deafness Source: American Annals of the Deaf. 144(1): 44-50. March 1999. Contact: Available from American Annals of the Deaf. KDES PAS-6, 800 Florida Avenue, NE, Washington, DC 20002-3695. Summary: The prevalence of smoking in different populations is thought to be influenced by sociocultural and linguistic factors. Although smoking and hearing loss are positively correlated, little is known about the smoking habits of deaf populations. This article reports on a study that used national survey data to determine the smoking prevalence in two socioculturally distinct deaf populations, based on age at onset of deafness. The smoking prevalence in each deaf population was compared to the smoking prevalence in the hearing population in multivariate analyses that adjusted for sociodemographics and health status. The smoking prevalence among postlingually deafened adults was not significantly different from that among hearing adults. Prelingually deafened adults were found to be less likely to smoke than hearing adults, even though they have less education and lower income, factors both associated with higher smoking prevalence in other populations. The authors hypothesize that the lower smoking prevalence among prelingually deafened adults may be due to cultural differences or to limited exposure to English language tobacco advertising. 1 figure. 4 tables. 32 references.

[email protected]. Summary: This article attempts to answer the main questions raised by that part of the deaf community which still considers cochlear implants (CI) an attack against the psychophysical integrity of the prelingually deaf. In this study, the psychological well being of six adolescents and six children was assessed pre and post implantation using various tools, i.e., projective tests, assessment scales, and structured interviews with parents and teachers. The analysis of post implant findings shows a reduction of stereotype elements, more dynamic modes of figurative expression, quite good relationships within their own social environment, and gradual, positive integration both at home and at school. The authors conclude that cochlear implantation seems to cause no psychological disruption. The sample group showed an improvement in their modes of expression (more consistent with the mental and effective age) and a greater awareness of personal limits, together with the ability to judge the appropriateness of their own behavior. 3 tables. 10 references.

[email protected]. Website: www.pediatrics.org. Full text of this article is available at www.pediatrics.org/cgi/content/full/108/1/e5. Summary: This article describes a rare inherited hypokalemic (low levels of potassium) salt losing tubulopathy (kidney disease) with linkage to chromosome 1p31. The authors conducted a retrospective analysis of the clinical data for 7 patients in whom cosegregation of the disease with chromosome 1p31 had been demonstrated. In addition, in 1 kindred, prenatal diagnosis in the second child was established, allowing a prospective clinical evaluation. Clinical presentation (symptoms) of the patients was similar and included premature birth attributable to polyhydramnios, severe renal (kidney) salt loss, normotensive hyperreninemia, hypokalemic alkalosis, and excessive hyperprostaglandin E urea, which suggested the diagnosis of hyperprostaglandin E syndrome and antenatal Bartter syndrome. However, the response to indomethacin was only poor, accounting for a more severe variant of the disease. The patients invariably developed chronic renal failure. The majority had extreme growth retardation, and motor development was markedly delayed. In addition, all patients turned out to be deaf. The authors conclude that this hypokalemic salt losing tubulopathy with chronic kidney failure and sensorineural deafness represents not only genetically but also clinically a disease entity distinct from hyperprostaglandin E syndrome and antenatal Bartter syndrome. A pleiotropic (causing multiple, seemingly unrelated symptoms) effect of a single gene defect is most likely causative for syndromic hearing loss. 6 figures. 1 table. 41 references.

[email protected]. Summary: This article describes a survey undertaken to compare the responses of 149 deaf students and 121 hearing students taking the same courses to a shortened and adapted version of the Approaches to Studying Inventory. In general, the impact of deafness on approaches to studying was relatively slight, and deaf students appeared to be at least as capable as hearing students of engaging with the underlying meaning of the materials to be learned. The authors used factor analysis to identify eight scales. Differences between the two groups were statistically significant on four of the scales. Discriminant analysis indicated that deaf students found it more difficult to relate ideas on different topics, and that this was more marked in those who preferred to communicate using sign. However, deaf students were more likely than hearing students to adopt a critical approach and to analyze the internal structure of the topics studied. 4 tables. 97 references.

Deaf Mentor Experimental Project for Young Children Who Are Deaf and Their Families Source: American Annals of the Deaf. 143(1): 29-39. March 1998. Summary: This article describes the Deaf Mentor Experimental Project, a project that investigated the efficacy of deaf mentor services to young deaf children and their families. These services focused on deaf adults (mentors) who made regular home visits to the children and their families; shared their language (American Sign Language), culture, and personal knowledge of deafness with the families; and served as role models for the children. The children also received regular home visits from a hearing parent advisor who helped the family promote the child's early listening, English, and literacy skills. The result was a bilingual, bicultural home environment for these children. The children who received deaf mentor services were compared to matched children who did not receive these services but who received parent advisor services. Children receiving the early bilingual, bicultural programming made greater language gains during treatment time, had considerably larger vocabularies, and scored higher on measures of communication, language, and English syntax than the matched children. 1 table. 38 references.

Summary: This article discusses issues of deafness and hearing loss related to HIV. The issues are examined from the following perspectives: 1) an HIV-positive person who experiences deafness as a symptom of the infection; 2) a culturally deaf person who develops HIV; and 3) a deaf professional who has HIV. Persons becoming deaf as a result of HIV are at risk of increased isolation, hopelessness, and vulnerability. They are forced to learn new methods of communication while under extreme stress, and may fail to gain treatment information. The author emphasizes the need to restore a sense of control and improve the quality of life for those who experience a hearing loss. The

culturally deaf are separated by language and community culture from communitybased support and services for HIV, and suffer from the deaf community's denial of the risks of HIV. A discussion of the use of interpreters highlights the confidentiality problem affecting the deaf, when they must either rely on a third party for communication or seek assistance from services staffed by deaf or signing professionals probably known to them. The author concludes with the following recommendations: develop programs linguistically and culturally sensitive to the deaf; increase access for the deaf in mainstream HIV/AIDS programs; and train HIV/AIDS counselors and therapists to communicate with deaf persons. •
Beyond Parent Education: The Impact of Extended Family Dynamics in Deaf Education Source: American Annals of the Deaf. 145(4): 359-364. October 2000. Contact: Available from American Annals of the Deaf. KDES PAS-6, 800 Florida Avenue, NE, Washington, DC 20002-3695. Summary: This article discusses the impact of childhood deafness on family dynamics, with particular attention given to the influence and role of grandparents. The author contends that models for the successful involvement of parents in the education of deaf children are already in place and can be applied to extended family, especially grandparents, with promising results. The author reviews an informal questionnaire study that focused on grandparents' support, involving 10 hearing parents of deaf infants and preschool children. How the child is treated within the extended family, how accommodations are made so that the deaf child becomes fully integrated into the extended family and its activities, and how extended family members relate and react to outsiders (medical or educational professionals) who may be involved in the child's care are important considerations for programs involved with young deaf children. Professionals must be aware of the needs of extended family members. Because they recognize that grandparents are mourning the loss of the idealized grandchild and their own idealized role as grandparents, schools and programs for deaf children and adults can provide them with information, networking opportunities, and support groups. 7 references.

Box 61556, King of Prussia, PA 19406-0956. Summary: This article explores how new discoveries in genetics will potentially impact the field of hearing and hearing disorders. For example, future gene therapies could alter the protein output that causes degenerative processes like hair cell deterioration in such conditions as presbycusis (age related hearing loss). The author notes that research is expected to focus on finding a way to prevent the deterioration of hearing in individuals who have a genetic predisposition to hearing loss. Genetic research can also play a part in determining who will be a good candidate for cochlear implantation. The author describes the etiology of hearing loss, how hearing loss is classified, the use of genetics to determine what is occurring in side the previously inaccessible cochlea, ethical concerns, and societal safeguards (notably privacy concerns). 1 figure.

The author reports on how the visual perceptual skills and cognitive processes of deaf people may be different from those in hearing people. The author suggests that deafness and the use of a sign language may selectively contribute to the development of such differences. However, there appears to be no overall enhancement of vision or visual perceptual skills in deaf people. The author discusses use of a global visual perceptual strategy, strategy differences in copying the Rey Osterrieth Complex Figure, diversity in the control of visual attentional skills, visual attention and the Stroop effect, visual attention and attention deficit disorders (ADD), diversity in processing written English,

Summary: This article reports on a study in which the speech perception and speech production performance following cochlear implantation of congenitally deaf children and children deafened by meningitis were analyzed. Three groups consisting of 70 congenitally deaf children, 22 children deafened by meningitis before two years of age, and 14 children deafened by meningitis after two years of age were compared. The group deafened by meningitis after two years of age demonstrated significantly better speech perception than the other two groups. Their speech production appeared better, but did not achieve statistical significance compared with the other two groups. There were no significant differences in speech perception or production between the congenitally deaf group and the group deafened by meningitis before two years of age. Further research is required to determine whether this is a consequence of meningitis, whether they have failed to derive benefit from their previous auditory experience, or whether any benefit they may have derived has been lost during their period of deafness. 2 figures. 9 tables. 15 references.

Changes in Otoacoustic Emissions in Patients with Idiopathic Sudden Deafness Source: Audiology. 36(3): 121-135. May-June 1997. Summary: This article reports on a study of changes in otoacoustic emissions in patients with idiopathic sudden deafness (ISD). Transiently click-evoked, distortion product, and spontaneous otoacoustic emissions were recorded. Changes in these tests were studied during the recovery process in 15 cases of ISD. In all these cases, the amplitudes of clickevoked and distortion product otoacoustic emissions increased concurrently with the recovery of the hearing threshold. Ears with ISD were not different in their otoacoustic emissions characteristics from ears with other forms of sensorineural hearing loss (SNHL). In 4 of the 15 cases, spontaneous otoacoustic emissions could be detected when hearing had recovered. These results suggest that the function of outer hair cells (OHCs) had deteriorated when the hearing threshold was elevated and that OHC activity recovered as hearing improved to nearly normal levels in ISD cases with good outcome. 7 figures. 1 table. 23 references.

Studies
19
months and at 3 years. The authors analyzed both the effects of child deafness and developmental change on pragmatic and dialogic characteristics of communication. From 22 months to 3 years, deaf and hearing children's communicative skills improved similarly along some dimensions. For example, as they grew older, both deaf and hearing children increased the amount they communicated, became increasingly responsive to their mothers' attentional focus, and were responsible for initiating a higher proportion of the dyads' conversations. On the other hand, deaf children were less skilled at maintaining topics, and the pragmatic function of their communication was more likely to be unclear compared to hearing children. Deaf children were also more likely to direct their mothers and less likely to ask questions than hearing children. Communication by hearing mothers was primarily examined to determine the degree to which they controlled the interactions. Overall, mothers of deaf children were only more controlling along one dimension. Mothers of deaf children used more response controls than mothers of hearing children. However, the majority of measures suggested that they did not exert more topic or turn taking controls than did mothers of hearing children. In addition, mothers of deaf and hearing children seemed equally sensitive to their children's communication abilities. Communication by mothers of both deaf and hearing children changed in similar ways as their children developed. Most of the differences in communication by mothers of deaf and hearing children seemed attributable to the deaf children's linguistic delays. The results suggest that intervention efforts should be focused on fostering linguistic development and not general communication skills or changing maternal conversational control. 8 tables. 42 references. •

[email protected]. Summary: This article reports on a study undertaken to examine the association between age at onset of deafness and mortality. The authors analyzed National Health Interview Survey data from 1990 and 1991 (the years the Hearing Supplement was administered) linked with National Death Index data for 1990 to 1995. Adjusting for sociodemographic variables and health status, the authors compared the mortality of three groups of adults older than 19 years: those with prelingual onset of deafness (onset at less than 3 years of age), those with postlingual onset of deafness, and a representative sample of the general population. Multivariate analyses adjusted for sociodemographics and strategies by age found that adults with postlingual onset of deafness were more likely to die in the given time frames than non deaf adults. However, when analyses were also adjusted for health status, there was no difference between adults with postlingual onset of deafness and a control group of non deaf adults. No differences in mortality were found between adults with prelingual onset of deafness and non deaf adults. The authors conclude that adults with postlingual onset of deafness appear to have higher mortality than non deaf adults, which may be attributable to their lower self reported health status. The authors note that their findings also raise questions that suggest more direct inquiry should be made about the modes of communication used by deaf people, in any future studies of this type. 3 tables. 25 references.

Support Services for Parents and Their Children Who Are Deaf or Hard of Hearing: A National Survey Source: American Annals of the Deaf. 142(4): 278-288. October 1997. Contact: Available from American Annals of the Deaf. KDES PAS-6, 800 Florida Avenue, NE, Washington, DC 20002-3695. Summary: This article reports on a survey completed in the spring and summer of 1996, by 404 parents of children who are deaf or hard of hearing and were born in 1989 or 1990. The questionnaires asked about early services received and the current status of the children's development. The children were enrolled in 137 different programs in 39 states; about one quarter of the programs participating in Gallaudet's Annual Survey of Deaf and Hard of Hearing Children and Youth. Children who are deaf comprised 46 percent of the group for whom responses were provided; those who are hard of hearing comprised 54 percent. Hearing loss was confirmed at the mean age of 14.5 months for the deaf group, and at the mean age of 28.6 months for the hard of hearing group. Additional conditions place 32 percent at risk for educational or developmental difficulties. One or both parents are deaf in 13 percent of responding families. Almost 40 percent of mothers have some training beyond high school; one third of the children came from minority backgrounds. Communication approaches used in children's initial programs included: speech alone (24 percent), sign and speech (66 percent), sign alone (5 percent), cues (3 percent) and sign and cues (3 percent). Parents gave highly favorable evaluations to intervention programs, and placed teachers at the top of a 'sources of help' list. Parents from minority groups and those with no college training reported that their children showed more behavior problems and less language progress, and gave more negative responses to questions regarding the impact of deafness on their families. This suggests that program personnel may need to increase their intervention efforts for these subgroups of special education consumers. 13 tables. 39 references.

[email protected]. Website: clerccenter.gallaudet.edu. Summary: This article reports on a survey that investigated residential schools and mainstreaming as educational options for children who are deaf or hard of hearing. Results were analyzed from 115 high school students, from 14 to 21 years old; 55 were from seven mainstream programs and 60 were from 4 residential schools. Almost all the mainstream students had hearing parents and a less than profound hearing loss. One fifth of them also had a compounding disability, ranging from learning disabilities to cerebral palsy. In contrast, one third of the residential students had at least one deaf parent and one half had a deaf or hard of hearing relative. The majority had profound hearing loss of 95 decibels or more. The author concludes that residential schools appeared to offer a stronger representation of deaf culture. These schools averaged 43 percent in hiring deaf teachers. American Sign Language is used to teach in these classrooms. A large majority of the students described themselves as 'Deaf' or 'deaf' and two thirds reported that they 'were happy to be deaf.' In contrast, mainstream programs reported 20 percent of their teachers were deaf and less than one third of the programs included American Sign Language in their instruction. One half of these students called

themselves 'Deaf' or 'deaf' and one half called themselves 'hard of hearing'; half reported that they were 'happy to be deaf.' The author emphasizes that, if access to deaf culture and student satisfaction are considered important, then it seems that placement in residential schools is ideal for teenagers who are deaf. •
Genes of Silence: Scientists Track Down a Slew of Mutated Genes That Cause Deafness Source: Science News. 153(3): 42-44. January 17, 1998. Summary: This article reports on recent findings in the field of genetics that may provide information about the auditory system and deafness. The deafness gene resembles a fruit fly gene called diaphanous, which has offered some clues to the human gene's possible role in hearing. The scientists are also investigating whether some cases of hearing loss stem from mutations in a second human gene that also resembles diaphanous. These two 'sister' genes are not the first nonsyndromic deafness genes isolated; another gene encoding a protein called connexin 26 was identified some months earlier. The author reports on family studies and on animal studies (in mice). As the genetic data accumulate, physicians may begin to screen for mutations that might cause late-onset hearing loss or counsel people about potential outcomes of future pregnancies. Mice will also serve as the initial testing ground for any treatments that might emerge from the discovery of deafness genes. 2 figures. (AA-M).

[email protected]. Summary: This article reviews some of the strides that have been made in the field of hereditary deafness. The authors note that, to date, mutations in at least 35 genes are known to cause hearing loss. The authors explore the possible biological roles of human deafness genes, focusing on those that have been identified in the past two years and that are known, or are suspected, to affect inner ear function when mutated. Topics include mutations affecting early inner ear development, mutations affecting sensory hair cells, mutations affecting melanocyte development, and mutations affecting endolymph homeostasis. The authors conclude that increased understanding of the function of these genes has not only provided insight into the molecular basis of deafness, but also of normal auditory function. 1 figure. 53 references (6 annotated).

The authors begin with a brief case report of a woman who realized that she was suddenly deaf in her left ear. The authors encourage readers to obtain a diagnosis, even for mild cases of hearing loss, because not only does the loss of hearing disrupt quality of life, but its occurrence could also signify a serious condition. Topics include diagnostic tests and the use of a detailed patient history in determining why sudden deafness has occurred; the audiological evaluation; sudden deafness in children; possible causes of sudden deafness; the role of trauma (which can interrupt blood flow to the inner ear); recommended actions when sudden deafness strikes; treatment options, including drug therapy and surgery; and spontaneous recovery from sudden deafness. 1 table.

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. Summary: This article reviews the genetics and molecular biology of deafness, stressing that otolaryngologists will increasingly play a role in the evaluation of people with hearing impairments. The authors outline three reasons that knowledge of genetics and molecular biology is becoming more important: during the past two decades, there has been a chance in the most common causes of severe and profound sensorineural hearing loss (i.e., less rubella, fewer trauma induced problems, and reduced use of ototoxic drugs); in the last decade, approximately 49 genes that cause hereditary hearing impairment have been identified; and, as genes that cause hereditary hearing impairment are located and closed, scientists gain information about the biologic mechanisms that likely will lead to new methods for treating and preventing sensorineural hearing loss. Hereditary hearing impairment can present as an isolated occurrence, or in association with a number of anomalies to be part of a syndrome. The screening of newborns for hearing impairment using the techniques of molecular biologists and geneticists will result in early identification and appropriate intervention for those at risk for hereditary hearing impairment. 1 figure. 6 tables. 41 references.

language, English based sign, and American Sign Language (ASL). Their potential contribution to literacy is mediated by four parameters on which they differ: codability, structural isomorphism, accessibility, and processibility. Finally, the author discusses the implications for additional research as well as for education. The author concludes that understanding and facilitating the acquisition of literacy by deaf children requires attention to a multitude of factors. As complex as this developmental task is in hearing children, it is rendered even more complex by the biological constraints attendant upon deafness and complex sociocultural milieu within which deaf children live and grow. 1 figure. 113 references. •

Summary: This article reviews the problems associated with noise-induced hearing loss (NIHL), particularly in older people. NIHL is caused by three related factors: the intensity of the noise, noise duration, and a genetically based sensitivity to noise induced deafness. The author reviews the occupations and activities that increase one's risk factors for NIHL, discusses eight myths regarding hearing loss and hearing, the contributions of age to hearing loss (including the role of presbycusis, or age-related hearing loss), the role of the general practitioner or gerontologist in identifying and managing hearing loss in their patients, how to help patients adjust to life with a hearing aid, and the kinds of assistive devices and equipment that can be helpful to patients with hearing loss. Topics include the negative impact of hearing loss on quality of life, tinnitus, the indications for hearing aids, the different types of hearing aids, the role of the audiologist, amplification, and listening environments.

Deaf Children and English: Parents Can Help Source: Perspectives in Education and Deafness. 15(3): 2-3. January-February 1997. Summary: This article reviews the strategies parents can use to help their children who are deaf or have hearing impairments learn English. The author notes that deaf people are so bombarded with the importance of learning English that the result is they some times become scared to use it. This fear can be debilitating, especially for children who are deaf. The article lists strategies for communication and building language skills. These tips include: model good reading behavior every day, watch sign language videotapes with the children, model using a dictionary, model writing at least once a week, communicate directly to the child in writing, buy a few special books and writing supplies for the children, play a word-based game at least once a week, learn special techniques for reading and writing to and with children who are deaf, clarify communication that is misunderstood, and ask others for help in creating a languagerich home environment.

Deafness
Summary: This article summarizes the activities of the World Health Organization (WHO) in its efforts to prevent deafness and hearing impairment caused by noise. The WHO Programme for Prevention of Deafness and Hearing Impairment (PDH) is especially targeted at developing countries where there is a serious lack of accurate population based data on the prevalence and causes of deafness and hearing impairment, including noise induced hearing loss (NIHL). However, opportunities exist for prevention of NIHL by primary, secondary, and tertiary means and it is necessary for countries to measure the size of the problem and adopt strategies for its prevention. The author describes the two WHO resolutions passed in relation to PDH (1985 and 1995); these resolutions affirmed that much deafness and hearing impairment is avoidable or remediable and that the greatest needs for the problem are in developing countries. WHOPDH addresses problems in this field of public health which are amenable to intervention, giving priority to the poorest developing countries. These problems include ototoxicity, chronic otitis media (ear infection) noise damage to hearing, inherited and congenital causes of deafness, and the provision of appropriate affordable hearing aid services. The PDH program has developed a standardized Ear Disease Assessment Protocol to enable countries to conduct national surveys rapidly. The article also reports briefly on a recent PDH meeting at WHO (Geneva, October 1997); the participants emphasized that NIHL is the most prevalent irreversible industrial disease and the biggest compensable occupational hazard. The meeting recommended that all countries implement the National Programmes for the Prevention of Noise Induced Hearing Loss, integrated with primary health care, including elements on health promotion and measures to reduce noise sources, and introduce legislation and effective hearing conservation. 2 tables. 7 references.

Website: www.sciencemag.org. Summary: This brief article reports on recent findings of new genes underlying genetic deafness. In Nature Genetics, moderate but dominantly inherited hearing impairment in two large families is shown to be a result of a mutation in the TECTA gene, on chromosome 11. Also, a report in this same issue of Science (May 29, 1998) finds that the unconventional myosin gene MY015 is mutated in the shaker-2 mutant mouse and in three human families with recessive, nonsyndromic deafness linked to chromosome 17, DFNB3. In addition, the discovery of alpha-tectorin mutations in people with hearing impairment suggests that the properties of the tectorial membrane are critical for delivering an appropriate stimulus to the hair cells. The authors briefly discuss these findings. The authors conclude by commenting that the difficult work is yet to come: establishing exactly what these molecules do in hair cells, and why each one has such a different effect on the ultrastructure of the developing cell. 10 references.

Website: www.agbell.org. Summary: This chapter is from a text that provides information on the language, speech, and social emotional development of very young children who are deaf or hard of hearing. In this chapter the authors report on a study of the relationships between several demographic variables and expressive vocabulary development. Basing their research on the MacArthur Communicative Development Inventory (CDI), the authors studied a group of 113 children who were deaf or hard of hearing (aged 24 to 37 months). The significant predictors of expressive vocabulary included the child's age, the age of identification of the child's hearing loss (before or after 6 months), the child's cognitive quotient, and the presence or absence of one or more disabilities in addition to hearing loss. The authors present normative data for expressive vocabulary development for children who are deaf or hard of hearing, for ages 8 through 37 months. The authors conclude that despite the apparent advantage in vocabulary ability evident in the early identified normal cognitive group of children, relative to previous reports on children who are deaf or hard of hearing, these children still appear to be delayed relative to data reported on hearing children. 5 figures. 6 tables. 53 references.

[email protected]. Summary: This editorial comments on an article in the same issue about the health care experience of elderly deaf patients (Witte and Kuzel). The editorial explores the availability and problems of medical care for the elderly Deaf in Richmond, Virginia (where the research study took place) and comments on health care delivery to the Deaf population at large. The author uses the word deaf to represent people with severe hearing impairment and Deaf (capitalized) to represent the subset that feels linked culturally. The editorial takes a realistic approach, reminding readers that many of the complaints or problems that Deaf people face in accessing health care are the same ones that hearing people face (hard to reach the doctor on the telephone, hard to get laboratory results, doctor uses big words that are hard to understand, nurses and secretaries speak too quickly). The author encourages physicians in communities with large Deaf populations (such as Washington, D.C.) to learn about the Deaf culture, but notes that most physicians in other communities will have neither the time nor the energy to do so. The author recommends some simple strategies that can improve communication with patients, regardless of the presence of a hearing loss. The author concludes by reminding readers that most Deaf do not consider deafness a handicap; rather, they consider it an inconvenience. The physician's caring and attention will serve to make their deafness less of an inconvenience. 1 reference.

(856) 848-1000. Fax (856) 853-5991. Summary: This editorial reminds primary care physicians of the importance of regular screening for and awareness of the symptoms of hearing loss in infants and children. The author describes the statistics of typical diagnosis of hearing loss in children, briefly considers the impact of universal neonatal screening,and helps readers understand the pathogenesis of hearing loss, with the goal of increasing the likelihood that abnormalities will be recognized. Topics include the qualities of sound: intensity or loudness (measured in decibels, dB) and frequency or pitch (measured in cycles per second, Hz); hearing evaluation tests; the physiology and anatomy of the inner ear; the different types of hearing loss and deafness; and the impact of noise in damaging the hearing. The author reminds readers that other anomalies arising from the same embryology as hearing anomalies are indications that hearing screening should be performed. In addition, it is recommended that a child be referred for a hearing screen if the family history is positive for deafness or if a parent has concerns about the child's hearing. 7 references.

Health Care Utilization and Adults Who Are Deaf: Relationship with Age at Onset of Deafness Source: HSR: Health Services Research. 37(1): 105-120. February 2002. Summary: This study analyzed data from the Hearing Supplement of the 1990-1991 National Health Interview Surveys to compare healthcare utilization for adults who became deaf before and after the age of three years old. Indicators of healthcare utilization included physician visits, private insurance, and preventive care such as blood pressure monitoring, pap smears, and mammograms. Overall, deaf adults reported a lower health status than hearing adults in the general population. Adults who became deaf prelingually (before the age of three) visited a physician less often than adults in the general population and adults who became deaf postlingually. Healthcare utilization for prelingually deafened adults was comparable to adults from language-based minority groups and may be attributable to language barriers. Postlingually deafened adults visited a physician more often than hearing adults in the

general population. However, mammograms were less common for postlingually deafened women, revealing a need to address specific prevention services. Future research should focus on the differences between subgroups of the deaf population and methods for improving communication between deaf persons and their healthcare providers. •

pumps to both assess and influence a 3-D tissue environment over time. Drug-delivery probes have been fabricated and used in acute experiments in the central nucleus of the inferior colliculus (CIC). The aim here is to adapt these probes to long-term chronic implantation and drug delivery to this deep auditory structure. Second, they would develop and test a new type of 3-D microelectrode array. It is based on the fabrication of two planar arrays that are connected by a forked silicon ribbon cable and that have recording sites which face inward and are mirror images of one another. This "Brain-ina-Box" (B-I-B) probe will be used in semi-chronic studies in the auditory cortex of awake cats. Major issues to be addressed in this proposal concern 1) chronic recording and drug delivery, 2) flexible but stable interconnect cables and 3) high-channel-count percutaneous connectors. To help guide new directions and developments in fabrication and assembly, the applicants proposed to conduct two animal experiments as test beds for the maturation of the technology. The objectives of the first project are to use 32-site, drug-delivery probes to examine the extent and patterns ("images") of central neural activation in the CIC of guinea pigs to various spatial and temporal configurations of electrical stimulation of the auditory nerve, to correlate these neural patterns with behavioral measures in the same animal and to examine how the patterns and behavior are influenced by time after deafness, intervention and manipulation. The goal of the second project is to use B-I-B probes to characterize the spatio-temporal patterns of cortical activation associated with the coding of soundsource location in the auditory cortex of awake cats. A semi-chronic paradigm will be developed that will permit study of a population of units for some days or weeks, followed by explanation and replacement of the probe at a different cortical site. The probes would sample neurons simultaneously at up to 32 sites, with a spatial scale of some hundreds of micrometers and a temporal scale of milliseconds to hundreds of milliseconds. The practical and logistical information gained from both studies will help guide modifications and refinements of the technology.

Project Title: A DEVICE ENABLING DEAF AND HEARING PEOPLE TO COMMUNICATE Principal Investigator & Institution: Curry, Emma; Scomm, Inc. Box 1509, 130 S Limit Sedalia, Mo 65301 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 31-DEC-2003 Summary: (provided by applicant): The goal of this research program is to explore the feasibility of developing a device to facilitate face-to-face communication between deaf and hearing people. sComm Inc. has had limited, but extremely positive, experience with a prototype device that allows two people to interact directly by typing messages to one another in a format that permits simultaneous display of both messages. Preliminary results suggest this straightforward approach is remarkably better than using an interpreter or handwritten messages. This work will be extended by investigating the willingness of hearing people to use this form of communication with deaf people in various settings, the willingness of deaf individuals to use the device and their experiences, the impact of the device on the employment of deaf people, the general impact of the device on the communication process, and the potential benefits of the device for deaf users beyond communication. In parallel, several design issues will be addressed to establish the feasibility of producing the device affordably. The importance of improved communication between deaf and hearing individuals cannot be overemphasized. Experience with the prototype suggests this device potentially can

remove many barriers, giving deaf individuals freedom through communication with hearing individuals on a one-on-one basis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: AAOHNS--CLINICAL TRIALS COOPERATIVE GROUP Principal Investigator & Institution: Brookhouser, Patrick E.; Director; American Academy of Otolaryngology-Head Head and Neck Surgery, Inc. Alexandria, Va 22314 Timing: Fiscal Year 2001; Project Start 15-APR-1997; Project End 31-MAR-2003 Summary: This application seeks support for a Clinical Trials Cooperative Group dedicated to the planning, conduct, analysis, and dissemination of results of clinical studies on the treatment or management of diseases and disorders of hearing, balance, smell, taste, speech, and voice or any combination. The Group structure includes: A Central Office (CO); a Central Trials Coordination Unit (TCU) experienced in the data management and statistical aspects of clinical trials; and a network of participating Investigator Groups (IG). This application proposes the American Academy of Otolaryngology-Head and Neck Surgery Foundation, Inc. (AAO-HNSF) as the CO; a group of senior investigators at the Bowman Gray School of Medicine Dept. of Public Health Sciences as the central TCU, and a group of highly experienced, researchoriented otolaryngologists representing over 20 major public and private university medical centers in the United States as the IG. The Otolaryngology Clinical Trials Cooperative Group (OCTCG) will have overarching responsibilities related to the development of clinical trials, selection of participating units, setting standards for conduct, quality control, and publications for individual clinical trials and for enhancing the disseminatIon of results from OCTCG clinical trials. The first trial proposed will investigate treatment of autoimmune inner ear disease, a potentially devastating condition that, left untreated, can lead to total deafness and disequilibrium in a very short time period. Available treatments for this condition (high dose prednisone methotrexate, cyclophosphamide) are currently utilized without proof of efficacy or assessment of risks. Using a multi institutional, prospective, double blind, placebo controlled design, the study will address the important clinical question of whether it is an acceptable risk to treat AIED with potent and potentially toxic immunosuppressive drugs when corticosteroids fail to control the disease. The dissemination of these results through the OCTCG should allow the timely transfer of information directly to clinical practice. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: AMINO ACID TRANSMITTERS IN THE AUDITORY BRAINSTEM Principal Investigator & Institution: Altschuler, Richard A.; Professor; Otolaryngology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2002; Project Start 01-DEC-1986; Project End 31-MAR-2007 Summary: Results now show a diversity in amino acid transmitters and receptor subunits that provide for the specialized shaping of neuronal responses and that their changes can underlie auditory brain stem plasticity. Our first Specific Aim is based on our finding decreased GABA release and correlated decreased inhibition in the inferior colliculus (IC) 3 weeks following deafness. It uses immunocytochemistry and tract tracing to test the hypotheses that decreased GABA release is a consequence of decreased GABA in terminals, with a specific GABA sub-circuit to the IC effected, rather than a "global" decrease in all inputs. Caspary's group found GABA-A receptor subunit

changes that correlated with age-related hearing loss, but couldn't differentiate "pure aging" versus "deafness". Our second specific aim uses quantitative in situ hybridization to test if there will be comparable subunit changes in our more "pure deafness" model, as well as changes in glycine receptor subunits in the DCN where a glycine mediated decrease in inhibition is found. We further hypothesize correlation between changes in transmitter and receptor. We predict GABA but not glycine receptor subunit changes in the CIC and glycine but not GABA receptor subunit changes in fusiform cells. Studies will also uses receptor autoradiography to test a functional correlate, ligand binding. Our final specific aim uses gene micro arrays to screen for differential expression following deafness and test the hypothesis that deafness induces decreased expression of presynaptic neurotransmitter- related genes and compensatory expression of postsynaptic genes. It then uses quantitative in situ hybridization to test the hypothesis that changes will be specific to distinct neuron types. These studies will provide new information on the role of transmitters and receptors in central auditory plasticity. This will, in turn, increase our understanding of the molecular basis of central auditory system dysfunction and provide clues for interventions that might help improve the reintroduction of hearing following deafness, currently with cochlear prostheses and in the future after hair cell regeneration.

Project Title: AUDITORY EXPERIENCE AND ADULT NEURON TURNOVER IN BIRDS Principal Investigator & Institution: Kirn, John R.; Professor; Biology; Wesleyan University Middletown, Ct 06459 Timing: Fiscal Year 2001; Project Start 26-JAN-2001; Project End 31-DEC-2003 Summary: (adapted from applicant's abstract) Neurogenesis persists into adulthood in many vertebrates including humans. An understanding of the factors that control neuron addition and survival may ultimately lead to insights on the functions of adult neurogenesis and suggest mechanisms for brain repair. In adult warm-blooded vertebrates, the most widespread production of neurons occurs in the avian telencephalon. In songbirds, many new neurons are inserted into the High Vocal Center (HVC), a region necessary for the perception and production of learned vocalizations. New HVC neurons replace older neurons that have died. Recent work shows that auditory input is necessary for normal rates of neuronal replacement. Available data suggest that deafening decreases the numbers of HVC neurons incorporated and prolongs their subsequent survival. Proposed work will directly test whether the life span of neurons that have been successfully incorporated into HVC prior to deafening is augmented. Additional studies will determine whether deafening influences the production or early survival of adult-formed neurons. A lesion study will test whether the lateral magnocellular nucleus of the anterior neostriatum (lMAN), an area necessary for song learning, participates in the auditory control of HVC neuron turnover. Playbacks of conspecific song produce increased rates of HVC neuron activity and maximal rates are obtained with playbacks of the bird's own song. Thus, the effects of deafening on HVC neuronal turnover may be due to depriving birds of song-related auditory stimulation. Proposed experiments will systematically deprive hearing-intact birds of access to self-generated auditory feedback and/or conspecific song to test this hypothesis. We will contrast these effects with those following manipulations that alter, without completely blocking, self-generated auditory feedback from singing. Collectively, these studies will explore the sensory requirements for the control of adult

Principal Investigator & Institution: Cotanche, Douglas A.; Director of Research, Associate Professo; Children's Hospital (Boston) Boston, Ma 021155737 Timing: Fiscal Year 2001; Project Start 01-JUL-1992; Project End 31-AUG-2006 Summary: (provided by applicant): The long-term objectives of this research are to understand the mechanisms that regulate hair cell regeneration in the avian inner ear and to apply this knowledge to induce regeneration in the mammnalian cochlea. Ultimately, the goal of this research is to utilize hair cell regeneration to ameliorate deafness in humans. Studies from the previous two funding periods of this grant have shown that the auditory epithelium in the postembryonic avian cochlea is mitotically quiescent. However, in response to sound exposure or aminoglycoside administration, the nonsensory supporting cells emerge from quiescence and divide to produce new hair cells that contribute to the structural and functional recovery of the cochlea. In this proposal, we will examine how the proliferative state of supporting cells in the avian cochlea is regulated by activating signals from dying hair cells competing with inhibitory influences generated by connexin expression in gap junctions of differentiated supporting cells. Our hypothesis is that signals released during apoptosis in hair cells induce the supporting cells to exit quiescence and begin proliferating and that connexin43 expression suppresses proliferation in supporting cells of the normal cochlea. The specific aims of this proposal will examine: 1) the role of apoptosis in regulating hair cell death and supporting cell proliferation in the regenerating cochlea; and 2) the role of connexin gene expression in suppressing proliferation of supporting cells in the normal and 'regenerating cochlea. In the first aim we will identify key proteins in the apoptotic pathway, block apoptosis by surgically implanting miniosmotic pumps in birds that will deliver inhibitors of apoptosis directly to the inner ear, and determine how apoptosis regulates hair cell survival and supporting cell proliferation. In the second aim we will define the expression of connexin isoforms in the regenerating cochlea and we will disrupt the regulatory function of connexin43 in normal and regenerating cochlleae by surgically implanting miniosmotic pumps that will deliver inhibitors of gap junction connectivity to the inner ear. These specific aims will be addressed utilizing in situ hybridization and northern blot analysis for mRNA localization and quantification, immunoblots of cochlear protein expression, miniosmotic pump delivery of chemicals directly to the inner ear, and confocal microscopy for immunocytochemical localization of proteins in sectioned and wholemount cochleae.

Project Title: CELL SURVIVAL IN A NEURAL CIRCUIT FOR LEARNING Principal Investigator & Institution: Johnson, James F.; Anthropology; Florida State University 118 North Woodward Avenue Tallahassee, Fl 323064166 Timing: Fiscal Year 2002; Project Start 01-JAN-1995; Project End 31-JUL-2006 Summary: (provided by applicant): Like humans, songbirds learn the sounds used by their species to communicate during a sensitive period of early development. In many songbird species only males learn to sing and a striking consequence of this behavioral

33
sex difference is that the brain regions for song control are prominent in adult males and diminished in size (or absent) in adult females. In the zebra finch, some vocal control regions initially develop in both sexes. However, during the juvenile phase of song learning these regions show substantial neuron death in females, and growth with little neuron death in males. Our working hypothesis is that the quality of song learning and the morphological development of song regions are influenced by how often juvenile birds practice their vocal pattern. A role for use-dependent mechanisms in motor learning and neural growth and plasticity has ample precedent in other animals, including humans. However, the contribution of use-dependent mechanisms in vocal learning (human or songbird) has never been evaluated, partly because of the difficulty of measuring a behavior that is voluntary and that occurs at high levels over the course of development. However, with the use of an event-triggered recording system (which allows continuous monitoring of the vocal output of individual birds), we have shown that daily song production is significantly greater in juvenile birds that are learning to sing than in adults. Individual differences in song production are also greatest in juveniles, and birds that sing more as juveniles have a higher quality song as adults. Thus, songbird vocal learning appears to involve a 'practice-driven' component, which may interact with maturational factors to influence neural development and determine the quality of the adult vocal pattern. Several gene products will be examined in this context to establish links between singing and 1.) storage of the effects of practice, 2.) mechanisms that drive the growth of song regions, and 3.) motivational systems that influence rehearsal of song by juveniles. All of the gene systems that we will study in zebra finches show a high degree of homology to their human counterparts, so what we learn about their role in songbirds may have functional implications for human brain development and vocal learning.

Project Title: CLINICAL & MOLECULAR ANALYSIS OF NEUROMUSCULAR DISORDERS Principal Investigator & Institution: Kimonis, Virginia E.; Pediatrics; Southern Illinois University Sch of Med Box 19616, 801 Rutledge St Springfield, Il 62794 Timing: Fiscal Year 2001; Project Start 25-JUN-2001; Project End 31-MAR-2002 Summary: (provided by applicant): Since the mid1980s, science has made tremendous progress in understanding genetics, including the roles that genes play in certain diseases. In particular, significant strides have been made towards identifying the molecular basis of neuromuscular disorders. These recent findings have initiated exciting studies of genebased therapies. The focus of our laboratory has been on the clinical and molecular pathogenesis of unique neuromuscular diseases of families from Central Illinois. The original K02 grant was for clinical and molecular delineation of a unique combination of features in a large family with CharcotMarieTooth and deafness. This ongoing study has led to the identification of a unique mutation in the PMP22 gene that cosegregates with the disease phenotype. We have recruited additional families to improve our understanding of this interesting phenotype. Molecular studies propose to examine the mechanism of hearing loss by determining patterns of PMP22 expression in the cochlea of mice throughout development and identifying new PMP22 mutations associated with deafness. As a result of our interest in neuromuscular disorders we have expanded our research interests to include another unique disorder: autosomal dominant limbgirdle muscular dystrophy in combination with Paget disease of bone and Alzheimer disease in some individuals. We have mapped this disorder to a unique focus on chromosome 9. The focus of our research is to identify the gene that disrupts

basic cell function and causes a myriad of phenotypes in this family. The aim of the current grant is to develop molecular and analytical techniques that will advance our understanding of CharcotMarieTooth disease, limbgirdle muscular dystrophy and other neuromuscular disorders. The suggested training will provide the PI with skills necessary to investigate the clinical and basic molecular pathogenesis of these disorders and aid in the development of novel treatment protocols.

Project Title: CLONING OF NON-SYNDROMIC DEAFNESS GENES DFNA29 & DFNA32 Principal Investigator & Institution: Li, Xiaoyan C.; House Ear Institute 2100 W 3Rd St Los Angeles, Ca 90057 Timing: Fiscal Year 2001; Project Start 09-FEB-2001; Project End 31-JAN-2004 Summary: (from applicant's abstract): The long-term goal of this study is to understand the function and dysfunction of hearing at the molecular level. Hearing impairment is the most common human sensory disorder. Approximately 70 million people worldwide suffer from hearing loss over 55 dB. Genetic factors are one of the most important causes for hearing impairment. Approximately one in every 2,000 children is born with severe to profound hearing loss due to a genetic cause. Non-syndromic hearing loss occurs in isolation, and it accounts for approximately 80% of hereditary deafness. Studies on the molecular basis of non-syndromic hearing loss, especially the late onset forms, are not only important for improving our understanding of the molecular mechanisms of auditory development and function, but also for developing more precise genetic counseling and therapeutics for both genetic and environmentrelated hearing impairment. We have mapped two new deafness loci, DFNA29 and DFNA32, using linkage analysis on two large US families with non-syndromic autosomal dominant progressive hearing loss. The PI proposes to identify the responsible genes, and to explore their function in the hearing process. The following specific aims are proposed: (1) Refine the critical region of DFNA29 and DFNA32 using recombinational mapping and linkage disequilibrium strategies. (2) Establish permanent cell lines from both affected and unaffected individuals by Epstein-Barr virus transformation. (3) Identify the molecular basis of these loci using a positional candidate gene approach. (4) Establish expression patterns of the genes responsible for DFNA29 and DFNA32 in the developing auditory and vestibular systems using PCR, RT-PCR, and RNA in situ hybridization. This specific aim represents a long-term direction of the study. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: CLONING TWO NEW DEAFNESS MUTATIONS Principal Investigator & Institution: Johnson, Kenneth R.; Research Scientist; Jackson Laboratory 600 Main St Bar Harbor, Me 04609 Timing: Fiscal Year 2001; Project Start 01-JAN-2000; Project End 31-DEC-2004 Summary: Impairment of hearing is the most common sensory deficit in human populations and affects about one of every 1,000 children. The mouse is an excellent model for studying human hearing disorders because of the anatomical and functional similarities between the mouse and human inner ears. In mice, mutations affecting the vestibular system of the inner ear often result in a characteristic circling or head bobbing phenotype; many of these mutations also affect the cochlea and cause deafness. Two independent spontaneous mutations responsible for such abnormal behavior were

35
discovered at The Jackson Laboratory and mapped to Chromosomes (Chr) 9 and 17, at positions where no other mouse mutations or deafness genes have been located. Both mutations when homozygous cause deafness, as assessed by the absence of auditory brainstem responses to stimuli greater than 99 dB SPL. Preliminary light microscopic analysis of cross-sections from cochleas indicate that both mutations cause neuroepithelial defects. Mouse mutations with similar defects have been shown to be models for human nonsyndromic hearing loss. On the basis of known human-mouse genetic map relationships, the new mouse mutations may be homologous to the human nonsyndromic deafness genes DFNB16 and DFNA13. The object of this proposal is to clone both of the mouse mutations by the positional-candidate gene approach. Preliminary mapping results have localized each mutation to within a 5 cM interval. These intervals will be further refined to less than 0.2 cM by recombinational analysis of extended linkage crosses. Physical maps will then be constructed and candidate genes within these regions will be screened for mutations. The human homologues of the genes shown to be mutated in mice will be identified for evaluation as candidates for human deafness. Mouse mutations enable studies of inner ear anatomy and development that are not possible in humans; such studies help elucidate pathways critical for the normal development and physiology of the ear. Another objective of this proposal is to establish a time course of pathology and gene expression in inner ears from mutant and control mice. The molecular identification and pathological characterization of these two new mouse mutations causing deafness will provide valuable models for understanding causes of hearing impairment in humans and for developing possible treatments and therapies.

Project Title: COMPLEX STIMULUS PERCEPTION WITH COCHLEAR IMPLANTS Principal Investigator & Institution: Chatterjee, Monita; Assistant Scientist; House Ear Institute 2100 W 3Rd St Los Angeles, Ca 90057 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2007 Summary: (provided by applicant):Cochlear implant listeners today enjoy reasonably good speech understanding in quiet but generally experience severe deterioration in performance in the presence of background sounds. To provide usable speech information through the cochlear implant in the presence of competing sources (speech or nonspeech), basic principles underlying the perception of complex, multichannel stimuli by the electrically stimulated auditory system need to be investigated. This proposal aims to investigate mechanisms underlying complex pattern perception by cochlear implant listeners. The long-term goal of this research is to discover fundamental principles of complex stimulus perception by both electrically stimulated and normal hearing auditory systems. Two hypotheses will be investigated: a) that principles of perceptual organization can be used by cochlear implant listeners for separating out sounds from multiple sources and b) noise is important in signal processing by biological systems in general and by the auditory system in particular, and the right kind of noise introduced into cochlear implants will be beneficial. The proposed experiments are designed to measure the perceptual interactions between pulse-train carriers with similar / dissimilar temporal envelopes exciting adjacent / distant tonotopic locations. Methods will include detection and discrimination of complex stimuli, perceptual difference measures, and auditory streaming measures. Effects of noise on the detection of envelope cues in single- and multi-channel complex stimuli will be measured. It is expected that this research will yield fundamental insight into mechanisms of auditory perception with cochlear implants. Because of their

fundamental nature, the findings are likely to also further our understanding of the normally functioning auditory system. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CONTROL OF INNER EAR DEVELOPMENT IN THE ZEBRAFISH Principal Investigator & Institution: Weinberg, Eric S.; Professor; Biology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-AUG-1996; Project End 31-MAY-2007 Summary: (provided by applicant): Studies on the genes involved in inner ear development should increase our understanding of human inner ear defects resulting in deafness and/or impairment of vestibular function. Although teleosts have a much reduced portion of the inner ear devoted to auditory reception, the vestibular portion of the inner ear is remarkably similar to that of mammals. Furthermore, the fundamental structure of the sensory epithelium is conserved in fish and mammals. The zebrafish embryo offers a number of advantages in the identification of genes that may be involved in inner ear defects, and in the experimental testing of the function of genes known to be expressed during the development of the inner ear. This proposal continues work that has been carried out in our laboratory on zebrafish inner ear development. We propose four Specific Aims. The first Aim directly continues our work on fate mapping of the specialized structures of the inner ear. In addition to completion of the fate map of the 24 hpf otic vesicle, we will carry out fate mapping of statoacoustic and anterior lateral line ganglia precursors. We will also trace cell movements and determine relative proliferation rates for various otic vesicle territories. These studies with wildtype embrv are essential to understand the cellular defects of mutants with defects in inner ear development. The se ond Aim continues our work on dog-eared, a gene we have demonstrated by positional candidate gene cloning to encode the Eyes Absent 1 (Eyal) protein. This finding demonstrates that the zebrafish is an excellent model for the study of human deafness disorders since mutations of the human EYA1 result in branchio-oto-renal syndrome. It is thus likely that other zebrafish inner ear mutants will be ot great relevance to the study of human deafness and vestibular disorders. In the third Aim of the proposal, we propose to molecularly identify quadro, a gene required for proper formation of the otic placode. quadro mutant embryos develop defects in otic placodal precursors between 12 and 13 hpf, resulting in a failure to properly express early markers of the placode and the dispersal and fragmentation of placodal tissue. We will apply the methods successfully utilized for dog-eared to the mapping and characterization of the quadro gene. The fourth aim of the proposal is a continuation of our mutant screen for defects in otic vesicle formation and patterning. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

range of basic and applied research projects from peripheral mechanics to cortical processing, from in vitro systems to human patients, from animal models to neural nets. The EPL research group has a long history of fruitful collaboration based on sharing of equipment, resources and scientific expertise via a system of research cores supported by a sunsetting program project grant. The current proposal builds on the present core structure and personnel to maintain existing, and facilitate further, interdisciplinary research efforts into hearing and deafness. Each of the Cores will support highly experienced personnel to 1) staff, stock, maintain and upgrade existing shared research facilities; 2) train users and/or render expert technical services in these facilities; and 3) provide the necessary expertise to enhance research productivity and facilitate the fusion of different research approaches across the many disciplines represented in the Research Center. The three Cores and the major aims of each include 1) an Engineering Core to design, build and maintain data-acquisition systems, custom acoustical devices, stimulus generation systems, a distributed multi-platform system for computational infrastructure and the local area network to link it all together 2) a Surgery/Histology Core to maintain existing shared facilities and assist research teams in animal surgery and histological preparation for both light and electron microscopy; and 3) an Imaging Core to support the growing needs of Center investigators for digital image acquisition and analysis, including confocal microscopy, computer-aided anatomical reconstruction, automation of morphometry, 3-D reconstruction/rendering, and analysis of functional imaging data.

Professor;
Timing: Fiscal Year 2002; Project Start 01-JAN-2002; Project End 31-DEC-2002 Summary: (provided by applicant): Scientific advances at our Research Center crucially depend on specialized computer-controlled experimental facilities for auditory research that are powerful and flexible enough to allow the efficient implementation of new paradigms. A major role of the Engineering Core is to design and maintain such specialized data-acquisition systems (Aim 1). This complex task involves selecting commercial instruments that are compatible with each other, installing these instruments, writing special software allowing them to be flexibly controlled by users, maintaining them, and upgrading them. Core Engineers also design and build electronic, acoustic and mechanical devices that are not commercially available (e.g. acoustic systems) to meet the constantly evolving requirements of experiments (Aim 2). Our diverse scientific needs require using several computer platforms (Macintosh, Windows and UNIX) inter-connected by a "Core Network 7" which insures highly reliable intra-laboratory communication. Continuing engineering effort is needed (Aim 3) to maintain the high reliability of this multi-platform network, reliability that is necessary for our networked data acquisition systems, and to meet new computational and data-storage challenges arising from the increasing use of gene chips, imaging and multi-electrode neural recordings. The function of the Engineering Core is to facilitate both current research projects and new initiatives by taking advantage of emerging and mature technologies. The Engineering Core makes it possible for individual investigators to use sophisticated (or simply complicated) techniques that they would otherwise not be able to develop or use. By providing shared experimental facilities, the Engineering Core also encourages collaborative projects among the investigators using these facilities. Finally, the Engineering Core makes the scientific research of the Center

more efficient by relieving investigators from many routine housekeeping computer tasks, and by allowing the same custom designs to be re-utilized in multiple setups. In short, the Engineering Core increases the quantity and quality of the Center's scientific output, allowing us to better attack new issues in hearing and deafness.

Project Title: CORE--SURGERY/HISTOLOGY Principal Investigator & Institution: Adams, Joe C.; Professor; Massachusetts Eye and Ear Infirmary 243 Charles St Boston, Ma 02114 Timing: Fiscal Year 2002; Project Start 01-JAN-2002; Project End 31-DEC-2002 Summary: (provided by applicant): The Surgery/Histology Core will provide the intellectual and physical environment in which Center Investigators, their trainees and support staff can learn and perform a variety of surgical and histological procedures. The Core will 1) maintain existing shared facilities for animal surgery, histological processing and electron microscopy and 2) provide technical expertise and training in surgical techniques (both acute and chronic) and histological techniques for tissue processing of both peripheral and central auditory structures at the light- and electronmicroscopic levels. Some complex surgical techniques, such as preparation of the anesthetized cat for neurophysiological study, will be routinely offered as a technical service. Some histological processing will be performed as a technical service, but only when task complexity task and limited project scope makes it inefficient to train the relevant group. Facility maintenance will include 1) ordering of supplies, 2) preparation of stock solutions, 3) equipment repair, and 4) compliance with local and federal regulations. All research groups in the Center will benefit by the time saved in not duplicating these basic services. All investigators will also benefit in several ways from the repository of experience and expert advice the Core represents. First, significant time will be saved by offloading to Core personnel the task of training new students and new investigator-specific support staff. Second, Core expertise will enhance the research endeavors of all participants by 1) facilitating the incorporation of new techniques and 2) by allowing them to use a wide range of techniques, each on a phasic basis, without having to maintain all the requisite skills within their own group at any one point in time. Core personnel include three experienced individuals (only partial support is requested for each) with demonstrated expertise in all relevant areas, including animal surgery, immunohistochemistry and a wide range of embedding and staining techniques for light- and electron-microscopic evaluation of peripheral and central auditory structures.

compare the quality of stimulus representation in the auditory cortex determined by various cochlear current configurations. Monopolar and other configurations that are presumed to produce diffuse neural activation will be compared with bipolar and other configurations thought to produce more focal activation. Experiments will be conducted in guinea pigs. Specific Aim 1 is to characterize the distribution of unit activity across cortical location and post-stimulus time in response to stimulation of a single cochlear channel. Multi-channel cortical recording probes will permit simultaneous unit recording at 16 cortical sites. Artificial neural-network techniques will test the accuracy with which cochlear stimulation channels can be identified on the basis of patterns of cortical activity. Stimulus current levels will be expressed relative to psychophysical thresholds assessed in individual subjects. Specific Aim 2 will test interactions between cochlear channels, using single pulses and amplitude-modulated pulse trains. Cortical phase locking to stimulus modulation will be quantified, then the influence of a simultaneous or interleaved masking pulse train presented on a second cochlear channel will be assessed. Animal psychophysical experiments in Specific Aim 3 will measure thresholds for modulation detection in the presence and absence of a masker on a second cochlear channel. Stimulus conditions will be compared that, in the cortical experiments, either minimize or maximize interaction between cochlear channels. Specific Aim 4 is to identify current configurations that are particularly suited to various histories of deafness and stimulation. The results will be used to examine the central mechanisms that underlie effects of duration of deafness and stimulation. These results will be used to examine the central mechanisms that underlie effects of duration of deafness on prosthesis function.

Three separate entities (DMSTAT, Inc., the Boston University Statistics and Consulting Unit at the College of Arts and Sciences and the Department of Biostatistics at the Boston University School of Public Health) have formed a group, DMSTAT/BU, proposing to collaborate with the CPEA network and to serve as its centralized data coordinating center (DCC). Our multi-disciplinary team of biostatisticians, epidemiologists, statistical geneticists, project managers, programmers and data managers can effectively and efficiently serve the ongoing and changing needs of the CPEA network. The primary goal of DMSTAT/BU is to provide integrated support to all CPEA project staff on two fronts: 1) consistent, efficient, cost-effective and high quality data management, and 2) biostatistical expertise in study design, randomization schemes, matching procedures, statistical genetics and multivariable analysis. DMSTAT/BU will assist project staff in the following areas: study design and protocol development, innovative processes to streamline data collection and increase data quality, administrative management, staff training, study monitoring, regulatory compliance, statistical design, analysis and reporting, and study documentation, in

addition to applying our proven data management and statistical analysis procedures, DMSTAT/BU will develop a website for the network which will serve as the backbone of the study infrastructure. The website will have administrative (e.g., e-mail links, meeting information, personnel contact information, project documentation, expense tracking) and data collection (distributed tracking and data entry systems) components. A reporting module in the website will make all of the administrative and data management information accessible to authorized members of the CPEA network. The team we have assembled has the requisite experience to effectively serve the needs of the CPEA network. The qualities that set us apart from our competitors are: innovation in streamlining and organizing processes, our abilities to educate and communicate with study staff at all levels, the breadth and depth of our analytic and statistical knowledge, our commitment to integrity in all aspects of data management, and our outstanding track record on studies of similar size and scope.

Project Title: CYTOGENETIC APPROACHES TO FINDING AUDITORY GENES Principal Investigator & Institution: Williamson, Robin E.; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-JUL-2002; Project End 31-MAR-2005 Summary: (provided by applicant): The goal of the research proposed is to use a cytogenetic approach to discover new deafness genes. Many genes of the auditory system have been identified through linkage studies of families that carry deafness as a heritable trait. This process is limiting in that a large number of affected individuals need to be analyzed to gain significant data. By ascertaining deaf individuals that carry balanced translocations, it becomes possible to discover disrupted genes with the genetic material of a single person. In this proposal, I plan to study two cases where the individual is deaf and carries a balanced translocation. Using the vast number of resources available now due to the progress made by the Human Genome Project, the sequence disrupted by these translocations will be identified. This will be done by progressively narrowing the breakpoint with FISH experiments using BACs and PCR products known to hybridize in the region. Candidate genes will then be identified by comparing the disrupted sequence to those already deposited in GenBank, or by analyzing these sequences with predication programs and methods. Ultimately, a mouse mutant may be created to confirm the pathogenesis of the disrupted gene. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: DEAFNESS AND OSSIFICATION IN LABYRINTHITIS OSSIFICANS Principal Investigator & Institution: Brodie, Hilary A.; Otolaryngology; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 95616 Timing: Fiscal Year 2001; Project Start 01-JAN-2000; Project End 31-DEC-2004 Summary: (Adapted from the Investigator's Abstract) Labyrinthitis ossificans (LO) is the growth of pathologic new bone within the lumen of the cochlea. It is multifactorial in origin and may result in deafness. Profound hearing loss and LO in children are most commonly associated with meningogenic labyrinthitis. The relationship of LO to meningogenic cochlear pathology and its mechanism of induction have not been clearly defined. Cochlear implants are a significant treatment option for improving hearing and quality of life in these patients. However, LO can reduce the efficacy of cochlear implantation. The long-term objective of this research program is to understand the mechanisms which lead to the development, progression, and destructive aspects of LO.

41
Such an understanding may lead to new strategies to prevent the devastating effects of hearing loss associated with this disease. The specific aims of this application are: (1) to correlate hearing loss with the temporal and spatial progression of bacterial meningitis from the subarachnoid space to the cochlea; (2) to correlate hearing loss with the temporal and spatial sequence for both labyrinthine fibrosis and ossification and the histopathology of cochlear tissues: spiral ganglion, organ of Corti, Reissner's membrane, stria vascularis, and spiral ligament; (3) to determine the relationship of bone lining cells to osteoblast formation and recruitment during labyrinthine neo-ossification; and (4) to determine the effects of decomplementation, non-steroidal anti-inflammatory compounds, and bacteriostatic vs. bactericidal antibiotics on neo-ossification and hearing loss. There are four hypotheses/specific aims outlined and they are as follows: Bacterial invasion of the cochlear labyrinth from the subarachnoid space correlates with hearing loss and occurs principally via the cochlear aqueduct and not the internal auditory canal; The destruction of cochlear tissue occurs subsequent to the arrival of inflammatory cells and not with the appearance of bacteria within the cochlea. Hearing loss may occur prior to observable pathology and reflect central auditory damage related to meningitis; Bone lining cells of the endosteum are activated and become mature osteoblasts and are the principal source of neo-ossification in labyrinthitis ossificans; and The inflammatory response to suppurative labyrinthitis includes fibrosis and neo-ossification formation and causes cochlear tissue destruction. Inhibition of this process will result in a reduction in both hearing loss and bone deposition. Methods used: The investigators propose to use an experimental gerbilline model of LO, histomorphometry, fluorescent bone histomorphometry, transmission and scanning electron microscopy, autoradiography, and auditory brainstem evoked response.

Project Title: DEAFNESS IN WS1: SEARCH FOR GENETIC MODIFIERS Principal Investigator & Institution: Pandya, Arti; Human Genetics; Virginia Commonwealth University Richmond, Va 232980568 Timing: Fiscal Year 2001; Project Start 01-AUG-1998; Project End 31-JUL-2003 Summary: As a pediatric geneticist, the P.I. has a keen interest in understanding the molecular pathology of inherited disorders, especially in children. The long term goal is to establish a career in academic medicine, which would allow the PI to study the importance of modifier genes for phenotypic variation in clinically relevant genetic disorders. Current Departmental projects are highly relevant to this proposal and will provide the necessary building blocks for the PI's career development. Hearing loss affects at least 5 percent of the population with the incidence of profound deafness at birth or during early childhood being estimated as about 0.8 per 1000. It is etiologically heterogenous, with genetic factors accounting for half of all cases of profound deafness, 10-20 percent of which are due to a specific hereditary syndrome. Waardenburg syndrome (WS) is a symptom complex that includes deafness, dystopia canthorum, white forelock and heterochromia. We participated in mapping the gene to 2q35 region, the discovery of genetic heterogeneity in WS, and in the demonstration of mutational heterogeneity at the PAX3 locus. The extensive phenotypic variation observed within WS1 families combined with the striking concordance for phenotype in MZ twins strongly suggests that modifier gene(s) contribute to this variability. The present proposes to identify and characterize the gene(s) causing deafness in individuals who have inherited a gene for WS type 1. We have identified 22 WS1 families with a minimum of 2 or more WS1 siblings who are both affected with deafness. This is ideal for mapping modifier gene(s) by an "affecteds" only approach. A two tiered mapping
42
Deafness
strategy involving a candidate gene search followed by a genome wide scan is proposed. Nonparametric methods of analysis will be used in addition to the traditional parametric approach to extract maximum information from families being studies. We will also further characterize the spectrum of PAX3 mutations in 30 available families with WS1 and study their potential interaction with the modifier gene(s). The successful identification of modifier genes which cause deafness in WS could lead to improved predictive testing. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: DEVELOPMENT OF CEREBRAL SPECIALIZATIONS Principal Investigator & Institution: Neville, Helen J.; Professor; Psychology; University of Oregon Eugene, or 97403 Timing: Fiscal Year 2001; Project Start 01-APR-1978; Project End 31-MAR-2002 Summary: (Adapted From The Investigator's Abstract): The broad goals are to characterize experience-dependent changes in the developing human brain and to test the hypothesis that they are determined by multiple, specific critical periods. The investigators will characterize the effects of auditory deprivation on the functional organization of the visual system, and the effects of acquisition of a visual-manual language (American Sign Language, ASL) and the effects of delayed exposure to language on the functional organization of different language systems of the brain. The investigators will test different conceptions of the identity and organization of subsystems within vision and language in studies of normal hearing adults. They will determine the nature of the effects and the time periods when altered experience affects the normal development of these systems in studies of congenitally and later deafened individuals, and in native and late leamers of ASL and English. The investigators will record event-related brain potentials (ERPS) and changes in blood oxygenation levels employing functional magnetic resonance imaging (FMRI) to characterize the timing and the location of neural activation as these groups of subjects perform tasks designed to activate specific aspects of sensory and language functions. They will assess the hypothesis, raised by our previous behavioral, ERP and FMRI studies, that there is considerable functional specificity in the alterations in the visual system and the language systems that can occur following auditory deprivation and that: 1. congenitally deaf subjects are more accurate and display faster and more extensive neural activation than normal hearing Ss when detecting, localizing and attending to visual events in the far periphery of the visual fields; 2. the neural systems that mediate this processing are more extensive in deaf Ss and include areas that process auditory information in normal hearing Ss; 3. there are several distinct subsystems within language and these differ in the degree to which they are dependent on and modified by language experience; 4. there is overlap in the neural systems within the left hemisphere that process ASL and English, but there is also extensive activation of the temporal and parietal regions of the right hemisphere for processing ASL only. Since these studies will determine the multiple, different time periods in human development when specific inputs from the environment have the greatest impact, the results will carry implications for the time periods when specific educational programs would optimize development in hearing and deaf children.

Studies
43
Timing: Fiscal Year 2001; Project Start 01-AUG-1989; Project End 31-MAR-2005 Summary: The long-term objective of this proposal is to identify the cellular mechanisms that regulate inhibitory synapse function during development and following hearing loss. The research plan is divided into three areas: (1) The regulation of inhibitory synapse strength will be studied in the developing gerbil lateral superior olivary nucleus (LSO), using a brain slice preparation. The activity-dependent depression of inhibitory synapses from the medial nucleus of the trapezoid body (MNTB) to the LSO will be examined with whole-cell voltage-clamp recordings. The relationship between depression and inhibitory synapse refinement will be tested with paired recordings from dye-filled MNTB and LSO neurons. The cellular basis for depression will be examined by direct activation or blockade of GABA and glycine receptors, and the use of transgenic receptor deletions in mice. The postsynaptic signalling pathway that induces depression will be tested by intracellular application of kinase and phosphatase antagonists. (2) The affect of deafness on inhibitory synapse function will be examined in the gerbil inferior colliculus. Using a brain slice preparation, gramicidin perforated-patch recordings will be obtained from IC neurons, and the evoked synaptic currents will be monitored in response to lemnisal or commissural stimulation. To determine why inhibitor synapse reversal potential depolarizes in deafened animals, postsynaptic chloride homeostasis will be examined in normal and deafened animals using chloride pump and voltage-gated chloride channel antagonists. The ability of synaptic activity to regulate chloride homeostasis will be assessed by monitoring inhibitory reversal potential before and after a prolonged period of excitatory or inhibitory activity. (3) The in vivo occurrence of inhibitory synaptic plasticity will be examined wit extracellular recordings from juvenile gerbils during sound stimulation. The strength of sound evoked inhibition in the LSO will be assessed before and after coactivation of excitatory and inhibitory pathways, using stimulus patterns that induce inhibitory depression in the LSO brain slice. To determine whether inhibitory synaptic strength declines in LSO following deafferentation, the inhibitory pathway will be stimulated electrically following cochlear ablation. The proposed experiments will demonstrate how inhibitory synapse physiology can be modified in the central auditory system, and suggest how inhibitory dysfunction could affect acoustic processing following profound deafness.

Project Title: DFNA1 IN INHERITED HEARING LOSS Principal Investigator & Institution: King, Mary-Claire; American Cancer Society Professor; Medicine; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 01-JUN-1991; Project End 31-JUL-2003 Summary: The investigators have studied a large Costa Rican family with autosomal dominant progressive non-syndromic hearing loss (DFNA1), and have recently through positional cloning identified a protein truncation mutation in the human homologue of the Drosophila diaphanous gene. This mutation was found in all deaf family members, and not in normal hearing family members or over 300 control individuals. The goals of this application are (1) to provide functional support for the pathogenicity of this mutation through a) generating mutant mice through homologous recombination and showing that these mouse mutants have a deafness phenotype (specific aims 1 and 3) and b) demonstrating that the protein abnormality leads to abnormal stability or intracellular localization (specific aims 2 and 4), (2) to start the study of proteins interacting with diaphanous which will elucidate the pathogenic pathway and provide candidate genes for other deafness genes (specific aim 5), (3) to study three other

Project Title: DROSOPHILA DEAFNESS GENES: ANALYSIS OF CHORDOTONAL ORGAN Principal Investigator & Institution: Eberl, Daniel F.; Biological Sciences; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2001; Project Start 01-APR-2001; Project End 31-MAR-2006 Summary: The long-term objectives of this proposal are to understand the molecular and cellular mechanisms of auditory mechanosensation. These goals will be achieved by using a new genetic model system for hearing in Drosophila. The public availability of almost the entire genome sequence, together with the genetic, developmental and molecular tools for manipulating Drosophila make this a very powerful model. Hearing in insects is mediated by chordotonal organs, which are related to vertebrate auditory and vestibular hair cells because they are developmentally specified by homologs of the same gene, atonal. The first approach will be to identify mutations that specifically disrupt chordotonal organ function, to clone the corresponding genes and to elucidate the cellular location and molecular function of their gene products. Mutations in three genes, beethoven, smetana and touch-insensitive-larva-B will be subjected to this analysis. The second approach will make use of enhancer trap strains, whose engineered transposon inserts express a reporter gene specifically in chordotonal organs. Four enhancer trap strains identified by this criterion will be used as starting points to clone the flanking sequences to identify candidate chordotonal-specific genes. If the transposon does not disrupt the gene, imprecise excision derivatives will be generated as a way to introduce mutations in the gene. The transposons therefore act not only as reporters, but also as molecular tags and as a mutagen. The third approach will use known human genes associated with deafness as a starting point to identify Drosophila homologs and then to use reverse genetics to identify mutations in these genes to test for function. Methods for this reverse genetic approach will include characterization of nearby transposon insertions or their imprecise excision derivatives as well as recently described gene replacement strategies. Identifying auditory genes by any of these approaches and elucidating the molecular roles of their products will provide very important insight into the fundamental but poorly understood process of mechanosensation.

Project Title: DRUG MANIPULATION OF NOISE-INDUCED HEARING LOSS Principal Investigator & Institution: Bobbin, Richard P.; Professor; Otorhinolaryngology; Louisiana State Univ Hsc New Orleans New Orleans, La 70112 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2003 Summary: (provided by applicant): The long-term objective of this research is to develop drugs that will decrease the effects of intense sound on the cochlea. Recent results from our laboratory have shown that PPADS, an ATP antagonist, decreases the effect of intense sound on the cochlea as monitored with distortion product otoacoustic emissions (DPOAEs). Our working hypothesis is that PPADS is blocking the effects of endogenous ATP acting on receptors on the perilymph surface of Deiters' cells.
Studies
45
Exogenously applied ATP depolarizes Deiters' cells and increases their intracellular free calcium levels. Deiters' cells are innervated by what appears to be branches of type II afferents to the outer hair cells (OHCs). This suggests that the source of the ATP acting on ATP receptors on the Deiters' cells may be the terminals of these nerve fibers. Anatomically, Deiters' cells are attached to the base and apex of OHCs, to the basilar membrane, and reticular lamina. Thus Deiters' cells may play a significant role in the transduction process carried out by the OHCs and their stereocilia. Deiters' cells may do this by altering their own stiffness. The hypothesis to be tested is that ATP, proposed as a neurotransmitter in the cochlea, reacts with receptors on the Deiters' cells to enhance the deleterious effects of intense sound on the cochlea. This hypothesis will be tested by experiments that: (1) determine if endogenous ATP enhances the deleterious effects of intense sound by testing ATP agonists and antagonists during intense sound exposure; (2) determine if the mechanism of action of ATP involves a movement of Deiters' cell or a stiffness change; and (3) determine if the receptor mechanism on Deiters' cells involves the metabotropic P2Y type of receptor.

Project Title: EXPRESSION OF ION CHANNELS IN THE AUDITORY SYSTEM Principal Investigator & Institution: Kaczmarek, Leonard K.; Professor; Pharmacology; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2001; Project Start 01-APR-1993; Project End 31-MAR-2006 Summary: The firing patterns of neurons in central auditory pathways encode specific features of sound stimuli, such as frequency, intensity and localization in space. The generation of the appropriate pattern depends, to a major extent, on the properties of the voltage-dependent potassium channels in these neurons. The Shaw-family Kv3.1 and Kv3.3 channels and the two-pore family rTWIK channel are expressed at high levels in neurons that are capable to firing at very rapid rates and that lock their action potentials to specific phases of auditory stimuli. We plan to determine the mechanisms that regulate these channels in the presynaptic terminals of cochlear nucleus neurons and their postsynaptic targets, neurons of the medial nucleus of the trapezoid body. To test the roles of these channels in timing and regulation of transmitter release, we shall record the responses of neuronal terminals and somata in which the genes for these channels have been eliminated by homologous recombination. We shall test the hypothesis that phosphorylation of the channel proteins alters the transmission of information through this synaptic pathway. Using transgenic animals in which the promoters for the channels are coupled to a fluorescent reporter gene, we shall test whether the naturally occurring differences in the level of expression of the Kv3.l channel along tonotopic axes can be induced by changes in the pattern of activity to which the neurons are exposed. An understanding of how ion channels are regulated in central auditory neurons is likely to lead to therapies for certain forms of deafness, as well as for tinnitus, disorders in the interpretation of auditory stimuli, and states of hyperexcitability such as audiogenic seizures.

Deafness
Summary: (Verbatim from applicant's abstract): Laminins are biologically-active molecules which function as cell adhesion molecules, regulate various aspects of development, and serve to stabilize complex anatomical structures. They are large extracellular matrix molecules that are composed of three subunit chains, designated alpha, beta and gamma. Five alpha, three beta and three gamma chains have been identified. Several disorders of the nervous system are linked to laminin genes: some congenital muscular dystrophies involve the alpha2 chain (merosin); the beta2 chain is reduced in Walker-Warburg syndrome, and a complex group of CNS developmental disorders (muscle-brain-eye disease; retinitis pigmentosa with deafness (RP21 with deafness); Walker-Warburg syndrome) map to the site of the gamma3 gene. Laminins are widely expressed in the CNS; we have shown that in the human, rat, bovine and mouse retina, four laminin chains (alpha3, alpha4, beta2 and gamma3) are found in the interphotoreceptor matrix and in the matrix of the outer plexiform layer (OPL). These chains are likely to form two heterotrimers, laminin-13 and laminin-14. The retinal laminin chains appear to play important roles in the morphogenesis of photoreceptors; first, these chains are expressed prior to the onset of rod genesis and persist into adulthood; second, ablation of the gene encoding one of the chains, beta2, results in the production of dysmorphic photoreceptors with aberrant function. Specifically, photoreceptor outer segments are reduced in length; the photoreceptor terminal in the OPL are disrupted: finally, in ERGs, the amplitude of the b-wave is drastically diminished, suggesting that transmission between photoreceptors and bipolar cells is disrupted by loss of laminin beta2 chain function. We hypothesize that laminins-13 and 14 are critical mediators of synapse formation and stabilization between photoreceptors and second order cells in the OPL. Furthermore, we hypothesize that laminins-13 and 14 form unique substrates with which photoreceptor axons interact and to which they adhere in order to elaborate synapses, and, finally, that the molecular structure of the synapse is dependent on the interactions between these laminins and their receptors. We propose to test several aspects of this hypothesis. We will ask several specific questions: (1) what the spatial and temporal expression of laminin-binding molecules is in the OPL; (2) whether these molecules mediate the binding of cells to OPL laminins; and (3) what anatomical and physiological alterations in the photoreceptor synapse result from laminin gene disruptions.

Project Title: FMRI OF PEDIATRIC COCHLEAR IMPLANT CANDIDATES Principal Investigator & Institution: Holland, Scott K.; Professor; Children's Hospital Med Ctr (Cincinnati) 3333 Burnet Ave Cincinnati, Oh 45229 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2003 Summary: (Provided by Applicant): This R21 proposal describes a feasibility study targeted for funding under the Neurosciences Technology Development program (PA98-050) through NICHD. The proposal outlines three aims necessary to develop functional magnetic resonance imaging (fMRI) technology as a tool for evaluation of pediatric candidates for cochlear implantation. FMRI is a relatively new and highly sophisticated technology, which can provide a window into the functional human brain. Cochlear implantation is also a cutting edge technology in approximately the same development phase as fMRI. The integration of these technologies presents a challenge. Successful integration of these technologies in very young children is a formidable proposition but offers the opportunity for new understanding of human deafness, cortical plasticity, brain development and connectivity. The proposal has three simple aims, which constitute the necessary preliminary steps toward development of fMRI
Studies
47
technology for use in pediatric cochlear implant candidates. We aim to: 1) Determine whether auditory cortical activity can be observed with fMRI with sound stimulation in sedated toddlers and young children with normal hearing; 2) Demonstrate that auditory cortical activity can be observed with fMRI using sound stimulation in compliant older children with severe to profound, sensorineutral hearling loss; and 3) Perform fMRI of auditory stimulation in severely to profoundly hearing impaired toddlers and young children under sedation. These aims define a logical course toward establishing that fMRI can be used successfully in pediatric cochlear implant candidates, many of whom are very young. If this feasibility study is successful, it will provide essential data needed to develop the neuroscience technology required to apply functional neuroimaging in severely to profoundly hearing impared toddlers and young children. This project will also more clearly define the potential role of fMRI in the selection and management of cochlear implant patients. The most optimistic outcome of this project would be that fMRI could be used to predict future benefit from a cochlear implant in a child. Short of achieving this high goal, this project will certainly accomplish the stated purpose of the Neurosciences Technology Development program (PA-98-050) of supporting "research that will develop significant enhancements to existing technologies important to neuroscience and research that will translate a scientific concept into the basis for a future technology that may advance understanding of important neuroscience research problems."

Project Title: FUNCTION AND STRUCTURE OF PENDRIN IN THYROID CELLS Principal Investigator & Institution: Kopp, Peter A.; Medicine; Northwestern University Office of Sponsored Programs Chicago, Il 60611 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 31-DEC-2007 Summary: (provided by applicant): Pendred's syndrome is an autosomal recessive disorder defined by congenital deafness, goiter and an impaired thyroidal iodide organification. It is caused by mutations in the PDS (Pendred's syndrome) gene. Mutations in this gene may be among the most frequent genetic causes of congenital deafness since they are not only associated with Pendred's syndrome, but they also form the molecular basis of two forms of non-syndromic deafness. The PDS gene encodes pendrin, an anion transporter belonging to the Solute Carrier Family 26A (SCL26A4). Pendrin is predominantly expressed in the thyroid, the kidney and the inner ear. Functional studies in Xenopus oocytes revealed that pendrin is able to transport chloride and iodide. In thyroid follicular cells, pendrin is expressed at the apical membrane suggesting that it could be involved in the transport of iodide into the follicular lumen. In the kidney, pendrin is found in beta-intercalated cells of the cortical collecting duct and is thought to function as a chloride/base exchanger. The exact role of pendrin in the inner ear remains unknown. Our preliminary data support the concept that pendrin is an apical iodide transporter. A detailed characterization of the anion transport properties of pendrin is essential for the understanding of its role in iodide transport in thyrocytes and the synthesis of thyroid hormones. At this point, there are no data on the kinetic properties of pendrin-mediated iodide transport, and its regulation. The membrane topology and secondary modifications of pendrin are unknown, and the determinants for PDS gene expression have not been characterized. The goals of this proposal are focused on studies addressing the function and structure of pendrin. The studies in Specific Aim 1 aim at further characterizing the iodide transport properties of pendrin. The experiments outlined in Specific Aim 2 seek to characterize the membrane topology and secondary modifications of pendrin and will

thus contribute to the elucidation of structure-function relationships. The experiments in Specific Aim 3 will determine the cell specificity of the pendrin promoter and study its regulation. These studies will provide fundamental insights into the (patho) physiology of this novel anion transporter that has important functions in the thyroid, the kidney and the inner ear.

Project Title: FUNCTIONAL AND MOLECULAR CHARACTERIZATION OF PENDRIN Principal Investigator & Institution: Karniski, Lawrence P.; Associate Professor; Internal Medicine; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2001; Project Start 01-FEB-2001; Project End 31-JAN-2005 Summary: (Adapted from applicant's abstract): Pendred syndrome, manifested by sensorineural hearing loss and goiter is the result of mutations in the PDS gene. PDS encodes a protein labeled pendrin that functions as a chloride, formate and iodide transporter and is expressed in the thyroid, inner ear and kidney. Pendrin's function is similar to a previously described chloride/formate exchanger that plays an important role in NaCl transport across epithelial cells, suggesting that pendrin might perform a similar role in the inner ear. Recent evidence suggests that some individuals with mutations in the PDS gene do not develop thyroid abnormalities but instead have nonsyndromic deafness with dilated vestibular aqueducts (DFNB4). The aims of this proposal are to characterize pendrin in terms of its function, location and regulation and determine how different PDS mutations affect pendrin. The following approach will be taken to achieve these aims: Polyclonal anti-pendrin antibodies (already generated by the Principal Investigator) will be used to identify the cell types in which pendrin is expressed. Pendrin function will be analyzed by determining substrate specificity, inhibitor profile, kinetics of transport and regulation, and chloride/bicarbonate exchange. The effect of different mutations in PDS on protein production, processing, regulation and transport properties will be examined. A knock out mouse model will be used to study the mechanisms of ion transport in cells where pendrin is normally expressed but rendered inactive. This work is a first step towards understanding the physiologic role of pendrin and determining how defects in pendrin lead to the clinical manifestations of Pendred syndrome.

Principal Investigator & Institution: Pfingst, Bryan E.; Professor; Otolaryngology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2001; Project Start 30-SEP-1997; Project End 31-JUL-2006 Summary: adapted from applicant's abstract): Deafness resulting from destruction of the inner ear is accompanied by partial degeneration of the auditory nerve as well as anatomical, physiological and molecular changes throughout the central auditory nervous system. These changes vary considerably among deaf individuals. By hypothesis, these individual differences are associated with the large differences across subjects in psychophysical and speech recognition performance with cochlear implants. In the set of experiments proposed in this application, we will use neurophysiological measures to characterize the large psychophysical changes that occur following

49
deafening and implantation of the cochlea. We will then examine the functional effects of post-deafening treatments, such as chronic electrical stimulation of the cochlea, that are intended to retard the long-term deleterious effects of deafness on the auditory system. The functional responses to electrical stimulation through cochlear implants will be assessed at the psychophysical level in humans and guinea pigs by measuring detection threshold functions and discrimination functions, and at the neurophysiological level in guinea pigs by measuring spatial and temporal responses of neurons in the inferior colliculus to electrical stimulation and by measuring gross potentials that reflect summed neural activity at peripheral (ECAP and EABR) and central (EMLR) sites along the auditory pathway. Three aims will be addressed. In Aim 1 we will compare psychophysical responses obtained from humans and guinea pigs to determine the relevance of guinea pig data to humans. In Aim 2 we will characterize the pronounced short-term effects of deafening and implantation procedures on the psychophysical and neurophysiological responses to electrical stimulation using the guinea-pig animal model. In Aim 3, we will test hypotheses about the functional benefits of post-deafening treatment of the ear. The results of these experiments will lead to better use of animal (guinea pig) models for auditory prosthesis experiments, they will provide a better understanding of the functional (diagnostic) implications of commonly used psychophysical measures such as detection threshold level, and they will have direct application to treatment protocols for deaf and severely hearingimpaired patients.

Project Title: GAP JUNCTION CHANNEL FORMATION AND GATING Principal Investigator & Institution: Bukauskas, Feliksas; Neuroscience; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2001; Project Start 01-FEB-1999; Project End 31-JAN-2003 Summary: Direct cell-to-cell diffusion of ions and cytosolic molecules is mediated by gap junction (GJ) channels. Each channel is a multimer of connexin (Cx) subunits that forms an intercellular aqueous pore b docking two pre-assembled hemichannels, one from each of two apposed cells. The first aim of this proposal is to study GJ channel formation as it relates to the events that occur after the establishment of cell-cell contact We utilize our ability to manipulate cells into contact while recording and uniquely combine electrophysiology of GJ formation with fluorescence imaging of Cx distribution in vivo real time. Cxs will be fused with enhanced GFP to allow their visualization. We will examine how the dynamics of Cx redistribution, such as plaque formation is associated with the establishment of electrical coupling. We will examine whether Cxs arrive at the junctional membrane from cytoplasmic stores of adjacent membranes and how membrane fluidity and extracellular Ca2+ affect the association between Cx distribution and GJ formation. We will also study the biophysical properties of de novo GJ channel openings, a process that we propose is a form of gating elicited by hemichannel docking. The second aim of the proposal is to test the hypothesis that the de novo opening of a GJ channel involves Cx domain(s) that are part of a ~common~ gate that is acted upon by different agents. Based on our studies of voltage and chemical gating of GJ channels formed of different Cxs, activators of this common gate include alkanols, H+ and membrane voltage. These agents close GJ channels completely, and the ~common gate~ may represent the principal means by which coupling is dynamically regulated in cell populations where voltages remain uniform. We will also examine gating by transjunctional voltage (Vi). We demonstrate that the Vi gate only partially closes GJ channels to a residual state whose conductance is Cx specific. We will examine

the ionic selectivity of the residual state and will assess the pore size of the residual and fully open states by measuring intercellular diffusion of uncharged dyes. The third aim of this proposal is to explore how Vi gating combined with the rectifying properties of open and residual states can play a role in regulating electronic transmission between excitable cells. Using heterotypic junctions, with combinations of Cxs that are present in the nervous system, we demonstrate conditions under which some heterotypic junctions exhibit nearly unidirectional transmission. These studies focus on defining the mechanisms that control GJ channel formation and gating which are ultimately necessary for determining the role of intercellular communication in normal and diseased states. Human genetic disorders that have been linked to Cx dysfunction include C-linked CMT disease, visceroatrial heterotaxia and sensorineural deafness.

Project Title: GENETICS AND PEDIATRIC NONSYNDROMIC HEARING LOSS Principal Investigator & Institution: Kenna, Margaret A.; Children's Hospital (Boston) Boston, Ma 021155737 Timing: Fiscal Year 2002; Project Start 16-AUG-2002; Project End 31-JUL-2006 Summary: (provided by applicant): Sensorineural hearing loss (SNHL) occurs in 4/1000 newborns. Until recently the work-up used a "shotgun" approach; many tests were ordered but the etiology remained unknown in 50% of cases. However, the recent use of genetic testing and high-resolution imaging has increased the yield of the SNHL evaluation. Mutations in the connexin 26 gene (Cx26) are responsible for approximately 50% of all recessive nonsyndromic SNHL allowing Cx26 gene testing to greatly expand the ability to provide an etiology for SNHL. This information can provide diagnostic as well as prognostic information to the patients, their families, and their physicians. The current proposal seeks to address several areas that have not been addressed by our studies or those of others. First, the audiologic phenotype of infants and children with SNHL and Cx26 mutations, both at the time of presentation and longitudinally, needs further definition. Second, it is not clear whether the audiologic phenotype varies with specific mutations or combination of mutations. Third, it is not clear whether CT scans of the temporal bones are ever routinely indicated in a patient with biallelic Cx26 mutations. Finally, in families of children with SNHL, it is not clear how well patients and families are being counseled to understand the benefits, drawbacks, and limitations of genetic testing or the results and implications of their genetic tests. It is also unclear why parents choose or decline genetic testing, and whether proper consent is obtained for such testing. We propose a clinical study to evaluate infants and children with Cx26related nonsyndromic SNHL. To accomplish these aims we will use 2 large patient populations from Children's Hospital Boston (CHB) including 1.Newborns referred after failing a newborn hearing screen; 2.Non-newborns with newly identified SNHL. There are four areas of concentration: 1.) Identification of Cx26 positive infants and children using genetic testing as part of the initial evaluation for newly-identified SNHL. 2.) The phenotype of the Cx26 related hearing loss will be studied, both at the time of diagnosis and prospectively over time. The rate and percentage of progression of Cx26 related hearing loss will also be evaluated. 3.) The diagnostic evaluation of the hearing loss will include temporal bone imaging studies, as the presence of anatomic temporal bone abnormalities is frequently associated with progression of the hearing loss and thus would affect the prognosis if present. Although temporal bone abnormalities have not been sought in large numbers of Cx26 positive patients, they are thought to be uncommon, at least for the two most frequently identified mutations, 35deIG and 67delT. However, recent studies suggest that temporal bone abnormalities may be

51
present in some patients with Cx26 mutations. If this were so, the prognosis of the hearing loss would be affected. 4.) For families of children with SNHL, we will utilize a questionnaire to determine why parents choose to have/not have genetic testing and to ascertain parents understanding of genetic testing. This information will be used to evaluate the effectiveness of genetic counseling associated with gene testing for deafness. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: GENETICS OF A NEW MOUSE MODEL FOR DEAFNESS Principal Investigator & Institution: Zheng, Qing Y.; Jackson Laboratory 600 Main St Bar Harbor, Me 04609 Timing: Fiscal Year 2001; Project Start 01-AUG-2000; Project End 31-JUL-2003 Summary: (adapted from applicant's abstract): Genetic impairment of hearing affects about one in every 2,000 children. Identification of genes leading to hearing impairment is essential for understanding factors necessary for normal auditory function and for development of therapeutic strategies. The genetic analysis of mouse deafness mutations has proven instrumental in the identification of several human deafness genes. A new mutation causing hearing and balance defects spontaneously arose in a colony of BALB/cByJ inbred mice at The Jackson Laboratory. The recessive mutation was named 'hypoplasia of the membranous labyrinth' (symbol hml) because it mainly affects inner ear morphology and development. The human homolog of the gene responsible for the hml phenotype in mice may play a role in the etiology and pathogenesis of some cases of human inherited deafness. Currently the pathogenetic mechanism and the identity of hml are not known. A small panel of intercross mice was used to map the hml locus to the middle region of mouse chromosome (Chr) 10. The genetic map position of the mouse hml gene suggests that the homologous human gene may be located on Chr 9pl3, where a particular form of genetic deafness in humans (DFNB15) has been previously mapped. In order to characterize the genetic and developmental dysfunction responsible for this morphogenetic inner ear mutation in mice, and ultimately extend that new found knowledge to improve our understanding of DFNB15 or other deafness traits in humans, the identification and characterization of the hml gene needs to be carried out. Aim 1. Generate a high-resolution genetic map of the region surrounding hml and screen candidate genes for the mutation. Aim 2. Construct a physical contig of YACS and BACS clones across the minimal genetic region. Aim 3. Fully characterize the development and pathology of inner ears from hml/hml mice compared with hml/+ and +/+ controls. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: GENETICS OF NOISE RESISTANCE IN THE AGING EAR Principal Investigator & Institution: Kujawa, Sharon G.; Massachusetts Eye and Ear Infirmary 243 Charles St Boston, Ma 02114 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2003 Summary: (provided by applicant): Hearing losses that accumulate with chronic exposure to high-level sound (noise-induced hearing loss; NIHL) and with age (agerelated hearing loss; AHL or presbycusis) are major health problems. They are common, their consequences are permanent, and their impact on human communication and quality of life is significant. Important advances have been made in characterizing the structural changes in the ear that underlie both NIHL and AHL, however, the mechanisms underlying these changes are still poorly understood. In human
52
Deafness
populations, hearing losses secondary to noise exposure and those attributed to aging are highly variable between individuals: some have 'tough' ears, while others have 'tender' ears. In contrast, work with laboratory mice has shown significantly less variability in NIHL and/or AHL within one inbred strain, while there are striking differences between strains. Our long-term goal is to exploit these strain differences in mouse models to study the genetic factors influencing susceptibility to NIHL and AHL, and interactions between them. Our immediate goals focus on the remarkable resistance to NIHL in the inbred mouse strain l29S6/SvEvTac (129S6), recently reported by the Liberman laboratory. Whereas NIHL typically grows rapidly once a critical exposure level is reached, NIHL in 129S6 grows 10 times more slowly over a wide range of exposure energy. Preliminary results from the Kujawa laboratory suggest that 129S6 also shows a type of AHL, demonstrating that AHL vulnerability need not be linked to NIHL vulnerability, as they appear to be in C57BL/6 mice. Further preliminary results from a Kujawa/Tempel collaboration suggest that both the AHL and the NIHL resistance in 129S6 are heritable as recessive traits. With this foundation, we propose to 1) better characterize the AHL and the influence of AHL on NIHL resistance in 129S6 using a number of physiological and histopathological measures, 2) provide a chromosomal localization for the major gene(s) influencing noise resistance in 129S6 using well-established techniques for genetic mapping, and 3) using the same genetic techniques, establish whether the AHL in 129S6 is mediated by the same gene locus associated with AHL in the C57BL/6 strain. The ultimate characterization of the genes influencing susceptibility to AHL and NIHL will provide fundamental insight into the cellular and molecular processes underlying cochlear degeneration, which, in turn, will be key to devising effective strategies to preserve hearing in human populations.

Project Title: HAIR CELL DEVELOPMENT IN THE INNER EAR Principal Investigator & Institution: Jiang, Rulang; Assistant Professor; Eastman Dentistry; University of Rochester Orpa - Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2001; Project Start 01-JAN-2000; Project End 31-DEC-2002 Summary: The long-term goal of this proposal is to understand the molecular mechanisms underlying hair cell development and patterning in the mammalian inner ear. Hair cells are specialized mechno-receptors that are responsible for sensing auditory and vestibular stimuli. Congenital or pathological loss of hair cells in human cochlea causes hearing loss, with a severity that correlates with the extent of missing hair cells. Recent analysis of mice carrying a targeted mutation in the Jagged2 gene, which encodes a cell surface ligand for the Notch family receptors indicates that Notch signaling mediates hair cell differentiation in the mammalian cochlea. Of the four known mouse Notch genes, only Notchl is expressed in the inner ear epithelium that gives rise to both hair cells and supporting cells, suggesting that Notchl may play an essential role in the hair cell development. interestingly, an autosomal dominantly inherited deafness syndrome has been mapped to the same chromosomal region as the human Notchl gene. However, targeted null mutations in the mouse Notchl gene cause early embryonic lethality. To characterize Notchl function in hair cell development, this pilot study examines potential defects in hair cell patterning in the Notchl heterozygous mice. In addition, new gain-of-function and hypomorphic alleles of mouse Notchl will be generated to further characterize the roles of Notch1 in hair cell development. These studies will lead to a better understanding of Notch function in hair cell development and will provide insights to studies of congenital deafness.

Project Title: ID OF THE MOUSE DEAFNESS (DN) GENE ON CHROMOSOME 19 Principal Investigator & Institution: Keats, Bronya J.; Professor; Genetics; Louisiana State Univ Hsc New Orleans New Orleans, La 70112 Timing: Fiscal Year 2001; Project Start 01-AUG-1999; Project End 31-JUL-2003 Summary: (Adapted from investigator's abstract) The overall goal is to identify the gene (dn) that is defective in the deafness (dn/dn) mouse. The applicants have mapped the dn gene to mouse chromosome 19 and it is likely to be the ortholog of the human DFNB7/11 gene on chromosome 9q13-q21. The deafness mouse is an autosomal recessive mutant of the curly-tail (CT) stock showing degeneration of the organ of Corti, stria vascularis, and the saccular macula. Ultrastructural abnormalities of the inner hair cells have been shown to be present at birth, and by 15-20 days after birth there are abnormalities of the extracellular spaces of the organ of Corti as well as loss of inner and outer hair cells. By 45 days after birth the inner and outer hair cells have degenerated completely, and the organ of Corti has no distinguishable cell types from base to apex. Interestingly, regeneration of cells other than hair cells occurs in the apical turn between 45 and 90 days after birth. Unlike other mouse models for deafness, the dn/dn mouse does not exhibit circling behavior, indicative of vestibular dysfunction, and therefore may provide insight into the auditory system as distinct from the vestibular system. Preliminary linkage and physical mapping data suggest that the deafness phenotype is associated with a chromosomal rearrangement, probably an inversion. Based on these results, the applicants propose to identify both breakpoints of the inversion, identify and characterize candidate genes, and create a hearing dn/dn mouse using transgenic technology. The specific aims are to: (1) Isolate and determine the sequence at both inversion breakpoints; (2) Identify candidate genes in the vicinity of the chromosomal rearrangement; (3) Isolate cDNAs and analyze for abnormal expression and gene structure in the dn/dn mouse relative to the +/+ mouse; and (4) Rescue the deafness phenotype via the transfer of BAC DNA directly into dn/dn mouse embryos. The deafness mouse is a model for nonsyndromic profound hearing impairment, and identifying the defective gene will be a valuable contribution to our understanding of the genes needed for normal cochlear function.

Principal Investigator & Institution: Andrews, William W.; Professor; Obstetrics and Gynecology; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2003; Project Start 17-APR-2003; Project End 31-MAR-2006 Summary: (provided by applicant): Preterm birth is the highest risk factor for cerebral palsy, other adverse neurological outcomes (such as blindness deafness, and mental retardation), and long-term adverse child health outcomes accounting for up to 50% of these adverse sequelae. Most of this morbidity is concentrated among the subset of preterm births that deliver at less than 32 weeks' gestation. Because of the increasing rate of preterm birth in the United States and the increased survival of infants delivered at the earlier gestational ages, the incidence of adverse long-term sequelae is rising. It is now well established that clinically silent upper genital tract intrauterine bacterial infection is strongly associated with a majority of preterm births that occur prior to 32 weeks' gestation. Additionally, emerging data implicate fetal in utero exposure to bacterial infection/inflammation as an independent risk factor for development of cerebral palsy and other adverse health outcomes, it is speculated that proinflammatory cytokine exposure may represent the link to these adverse outcomes. Most of the studies linking infection to adverse neurological outcomes have been limited to short-term neonatal outcomes including markers for subsequent development of cerebral palsy such as periventricular leukomalacia. Long-term follow-up studies in this area are sparse, are largely limited to cerebral palsy as the primary outcome, and provide limited information regarding the maternal/neonatal clinical course. The current literature lacks a longitudinal study with extensive maternal and neonatal clinical, laboratory, microbiological, and histological data on a cohort of maternal-infant pairs on whom long-term outcome evaluation is available including not only cerebral palsy but also other important neurodevelopmental and health outcomes. We hypothesize that in utero exposure to infection/inflammation is associated with increased risk of adverse neurodevelopmental and child health outcomes at age 4-7 years. We propose to test this hypothesis in a cohort of 424 maternal-infant pairs that delivered at our institution between 24 weeks 0 days and 31 weeks 6 days gestation. This cohort has already been studied resulting in an extensive database that includes almost every detail of antepartum, intrapartum, and neonatal clinical data. Also already available from this cohort are histological, microbiological, and biochemical data including umbilical cord blood and neonatal cultures, umbilical cord blood cytokine data, placental histology, and placental cultures. We propose a longitudinal follow-up study of this preterm cohort in order to systematically evaluate the relationship between maternal/fetal infection, fetal exposure to inflammation, neonatal short-term outcomes and ultimate neurodevelopmental outcomes at age 4 to 7 years (Aims 1 and 2) including the potential influence of effect modifiers such as environmental factors and caregiver characteristics (Aim 3). We will also determine if umbilical cord blood markers of neuronal damage are associated with short-term or long-term outcomes (Aim 4) and the strength of association between in utero infection/inflammation, bronchopulmonary dysplasia and long-term indicators of pulmonary dysfunction (Aim 5).

55
Timing: Fiscal Year 2001; Project Start 15-AUG-2001; Project End 31-JUL-2004 Summary: (provided by applicant): Noise-induced hearing loss (NIHL) is the most common occupational disease in the United States, yet it's mechanisms are not fully understood. The goal of this application is to determine whether and how hypoxia can interrupt auditory function transiently. People may suffer from insufficient blood oxygen supply due to pulmonary or cardiovascular disease, altitude, and environmental pollution by chemical asphyxiates. The risk of environmental noise may be tremendously increased when the noise is under hypoxic conditions. As indirect evidence, carbon monoxide (CO) exposure, which among other effects reduces oxygen supply to tissues, potentiates permanent NIHL at a level that alone does not cause a permanent threshold loss. The investigation of effect of hypoxic inhalation on NIHL will provide a direct test of the susceptibility of the cochlea to reduced oxygen tension. In this application, noise intensity will be varied from lower than the current permissible exposure level (PEL) to 120 dB SPL. Noise intensity higher than 120 dB SPL may cause some mechanical damage to the cochlea. Oxygen level in the exposure chamber will be varied from the normal level (21%) to 6%. Hypoxic inhalation alone with oxygen level lower than 6% may cause a temporary auditory function loss. The designed experiments will measure: (1) noise-induced and noise+hypoxia-induced hearing loss and hair cell loss 4 weeks after the exposure; (2) free radical generation, succinate dehydrogenase (SDH) activity reduction and apoptotic cell death in the cochlea immediately after the exposure; and (3) time course of these biochemical alterations and the protective effect of a free radical scavenger against SDH-activity reduction and apoptosis. We hypothesize that the noise under hypoxic conditions will generate more free radicals than noise alone, which then impair mitochondria, causing a reduction in SDH activity and also release of cytochrome c that may cause apoptosis. We further hypothesize that free radical scavenging will protect against SDH activity reduction and apoptosis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: INNER EAR CONSORTIUM (CORE CENTER) Principal Investigator & Institution: Baird, Richard A.; Senior Scientist & Center Head; Central Institute for the Deaf 4560 Clayton Ave St. Louis, Mo 63110 Timing: Fiscal Year 2001; Project Start 26-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): We are requesting funds to support a recently constituted Inner Ear Core Consortium designed to enhance exiting research programs and to promote cooperative interactions among 18 scientists at Central institute for the Deaf (CID), Washington University Medical School (WUMS), and St. Louis University (SLU). This consortium consists of an administrative Core Center, three researchoriented core facilities (Digital Imaging Core Electron Microscopy Core, and Gene Expression Core), and one service-oriented core facility (Electronic Services Core). These core facilities are physically located in a new CID research building, recently completed and occupied, immediately adjacent to the south end of the WUMS campus. The scientists in the Inner Ear Consortium have research backgrounds in anatomy, biochemistry, cell biology, developmental biology, molecular biology, molecular genetics, and physiology.

Consortium maintains expensive common equipment, supports the common needs of inner ear scientists for digital imaging, ultrastructural analysis, and studies of gene expression. It encourages research collaborations that cross existing research programs by promoting interactions among (1) researchers who study the morphology and physiology of the normal, developing, and regenerating inner ear, (2) researchers who study the inner ear on systemic, cellular, and subcellular levels, and (3) researchers who study the auditory and vestibular systems. It promotes the use of mutant and transgenic animal models and trains inner ear scientists in new research techniques, fostering the transfer of these techniques among inner ear laboratories. The Inner Ear Consortium also provides limited assistance for pilot projects, especially those that advance existing scientific programs, involve multiple investigators, or promise to provide new techniques of general interest to inner ear scientists. Finally, it enhances the research training that consortium members provide to residents and medical students in the Department of Otolaryngology and graduate students in the Departments of Speech and Hearing Sciences at CID and the Division of Biology and Biological Sciences at WUMS.

Project Title: INNER EAR GAP JUNCTIONS FOR HEARING Principal Investigator & Institution: Zhao, Hong-Bo; Otolaryngology; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2001; Project Start 01-AUG-2000; Project End 31-JUL-2002 Summary: The long-term goal of this project is to investigate how gap junctional coupling in the organ of Corti contributes to normal hearing. Gap junctional coupling is extensive between the cochlear non-sensory cells. There is no gap junctional coupling between sensory cells (inner and outer hair cells) or between sensory cells and supporting cells. Disturbances of inner ear gap junctions are known to be associated with a high incidence of non-syndromic deafness. Hypothetical functions of gap junctions in the cochlea may involve nutrition, passage of ions and small molecules, and maintaining intracochlear electrochemical gradients. A gap junction channel is composed of connexin proteins; each cell side has 6 connexin subunits. More than 5 connexin genes have been identified in the cochlea. Recording of macroscopic current (containing many channels) has demonstrated that gap junctional coupling in supporting cells has variables transjunctional voltage (Vj) dependence and membrane potential (Vm) dependence. This indicates complex channel constitutions. The specific objective in this proposal is to identify types of gap junctional channels in the cochlear supporting cells by single channel recording. A double voltage clamp technique will be used to record the single channel activity. Transjunctional current will be measured on weakly coupled cell pairs or using uncoupling agents, such as CO2 and octanol, to diminish the cell coupling. Single channel conductance, kinetics and voltage dependence on either cell side will be examined to identify the channel configuration. Acetylcholine (Ach) and cyclic nucleotide will be applied to cells to test the possible gating regulation. The results of these studies may provide clues as to functional gap junctional pathways in the inner ear, and improve our understanding of their contributions to normal mammalian hearing. This information may be clinically relevant for physicians treating patients with deafness induced by connexin mutations. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Animals will be raised in a sound-isolating environment, and hearing testing will be performed on each ear before and after exposure of a single ear to noise at a level intended to produce a mild hearing loss. Dr. Boettcher will investigate whether susceptibility to noise-induced hearing loss varies as a function of age, and whether a non- traumatic conditioning sound can reduce the magnitude of age- related hearing loss. Dr. Boettcher will measure auditory threshold using auditory brainstem responses, and will also, in a subset of animals, obtain measures of histopathology of the stria vacularis, hair cells and eighth nerve fibers.

Project Title: LANGUAGE, MODALITY AND THE BRAIN Principal Investigator & Institution: Emmorey, Karen D.; Senior Staff Scientist; Salk Institute for Biological Studies 10010 N Torrey Pines Rd San Diego, Ca 92037 Timing: Fiscal Year 2001; Project Start 01-JUL-1979; Project End 31-MAR-2004 Summary: Sign languages provide a powerful tool for investigating the neurobiology and cognitive architecture of human language. For perception, these languages depend upon high-level vision and motion processing systems; for production, they require the integration of motor systems involving the hands and face. What impact does this different biological base have on language processing? How does it affect non-linguistic cognitive functions? Are the same neural systems involved? We investigate these issues by studying neurologically-intact deaf signers, focusing on a coherent set of cognitive functions implicated in the processing of sign language. We proceed along the primary lines of inquiry: I. The effects of spatialization on language. We investigate a unique aspect of sign language: the linguistic use of physical space. We will examine on-line comprehension of spatialized co- reference, the nature of linguistic use of physical space. We will examine on-line comprehension of spatialized co-reference, the nature of linguistic versus cognitive spatial categories, and the relation between spatial gestures and spatial signs. For the first time, we will investigate the representation and processing of cross-linguistic study of how different sign languages express topological spatial relations. Together, these studies will indicate how the visual-spatial modality impacts grammatical form and language processing. II. The interplay between language and visual-spatial cognition. Our proposed studies are motivated by exciting findings under the current grant which show that processing the complex spatial system of American Sign Language (ASL) exerts selective enhancement of non-linguistic visualspatial processing. We investigate the impact of sign language use on the following cognitive functions; motion perception and analysis, the recognition and categorization of human faces and facial expressions, and visual-spatial imagery. A major goal is to determine how the language one uses can affect cognitive processes in non-linguistic domains. III. The neural bases for language and spatial cognition in deaf signers. The unusual sensory and linguistic experience of deaf ASL signers provides a natural opportunity to investigate neural plasticity and the determinants of brain organization.

Project Title: MAPPING DEAFNESS GENES USING GENOMIC MISMATCH SCANNING Principal Investigator & Institution: Cheung, Vivian G.; Assistant Professor; Children's Hospital of Philadelphia 34Th St and Civic Ctr Blvd Philadelphia, Pa 19104 Timing: Fiscal Year 2001; Project Start 01-FEB-1998; Project End 31-JAN-2003 Summary: Hearing loss affects over 40 million people in the United States. It is the most common form of sensory defect in humans. The mechanism of hearing is still largely unknown despite recent advances in molecular medicine. The goal of this proposal is to apply two molecular biology techniques, genomic mismatch scanning and DNA microarray, to gain a better understanding of the genetic basis of hearing loss. This will eventually affect the prevention, treatment and care of hearing disorders. Genomic mismatch scanning (GMS) is a high-throughput genetic linkage technique that allows physical isolation of the identical-by-descent DNA fragments shared between two related individuals. In this proposal, we plan to apply GMS to confirm the localization for DFNBI, the gene for non-syndromic autosomal recessive deafness that has been mapped by linkage to chromosome 13q. Then, we will narrow the DFNBI candidate region using linkage disequilibrium mapping. This has been difficult with traditional mapping strategies due to the need for a very dense set of polymorphic markers. However, in GMS, a dense set of completely informative markers is scanned simultaneously on a whole genome level. In addition, during the grant period, we will develop a DNA microarray that will allow mapping of the identical-by-descent DNA fragments isolated by GMS on a whole genome level in one hybridization step. This DNA microarray will allow mapping of other deafness loci with unknown genomic locations. Finally, we will develop a linkage analysis model for the identity-by-descent maps generated by GMS. Upon achieving the goals delineated in this proposal, we hope to have contributed to the understanding of the genetic control of hearing and have provided a robust method that is a promising tool for the next generation of gene mapping.

Summary: (provided by applicant): Sensory hair cell loss is the leading cause of deafness in humans. The mammalian cochlea cannot regenerate its complement of sensory hair cells and thus at present, the only treatment for deafness due to sensory hair cell loss is the use of prosthetics such as hearing aids and cochlear implants. Strategies for hair cell repair that involve either stimulation of quiescent cells in the mature organ of Corti, or which involve transplantation of progenitor cells able to differentiate into hair cells will require markers to identify such cells, as well as a detailed understanding of hair cell precursor biology. However, progenitor cells that give rise to hair cells of the mammalian inner ear are currently uncharacterized, largely because no definitive makers are available for their identification. We propose a pilot project to develop molecular genetic markers that identify unique subpopulations of otic epithelial progenitors. To accomplish this, we will use an important new resource (The Gensat Project) to identify markers of sub-populations of cells in the developing inner ear. This is a collection of transgenic animals that harbor bacterial artificial chromosomes (BACS) as transgenes and which express Green Fluorescent Protein (GFP) under the control of a single gene contained in the BAC. In each transgenic animal, GFP is expressed in a unique sub-population of cells dictated by the expression pattern of the gene in question. We have identified current BAC Transgenic Collection, with a list of genes reported in the literature to be expressed in the inner ear has identified twentythree genes expressed in the inner ear. To explore the usefulness of the BAC Transgenic collection, we propose to analyze four BAC transgenic animals chosen from among this group, based on their potential to add to our knowledge of sensory hair cell progenitors. In Specific Aim 1, each transgenic line will be characterized developmentally for expression of GFP in otic sub-populations each sub-populations will be purified by Fluorescence Activated Cell Sorting. In Specific Aim 2, GFP-expressing sub-populations will be assayed for their ability to differentiate into hair cells using a newly developed dissociated culture system for sensory epithelium. In the Specific Aim 3, the same purified otic epithelial sub-populations will be profiled using micro-arrays to provide initial information about gene expression networks in the developing inner ear.

Project Title: MEASURING HIV/AIDS KNOWLEDGE AMONG THE DEAF Principal Investigator & Institution: Goldstein, Marjorie F.; Social Sciences Innovations Corporation 71 W 23Rd St, 8Th Fl New York, Ny 10010 Timing: Fiscal Year 2002; Project Start 27-SEP-2000; Project End 31-MAY-2004 Summary: (provided by applicant): This Phase II SBIR application proposes to use Interactive Video Questionnaire technology to interview individuals who are deaf about their HIV/AIDS knowledge, attitudes, and behaviors using a sign language questionnaire to be self-administered on laptop computer. In order to meet the linguistic and cultural needs of the deaf population who use American Sign Language (ASL) as their primary communication modality, survey options will include: standard ASL, and highly contextualized ASL (each with optional captioning), and a captions-only version. Building on translation work that began in Phase I (using a bilingual translation team) and former related research, we will translate 200 HIV/AIDS related items, videotape these and digitize them for use on 12 laptop computers. The survey will then be administered to 1000 individuals who are deaf. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: MEMBRANE TRAFFICKING AND CHANNEL ABUNDANCE Principal Investigator & Institution: Jan, Lily Y.; Professor and Hhmi Investigator; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2001; Project Start 15-AUG-2001; Project End 31-JUL-2006 Summary: (Provided by Applicant): For signaling to proceed normally in the nervous system, there has to be the right number of the right type of ion channels and transmitter receptors on the neuronal membrane. What kind of quality control machinery can ensure the proper assembly of these membrane protein complexes? How does a cell control the number of channels and receptors on its cell membrane? We have found a novel quality control mechanism that curtails the trafficking of inadequately assembled membrane protein complexes from the endoplasmic reticulum (ER) to the cell membrane. This ensures surface expression of fully assembled ATP-sensitive potassium (K-ATP channels with four Kir6.2 and four SUR subunits, and of properly assembled, heterodimeric GABA-B receptors that can functionally couple to the G protein-activated inwardly rectifying potassium (GIRK or Kir3) channels. The ER retention/retrieval signals in the K-ATP channels also limit the number of these channels on the cell surface. How general might be the use of ER retention/retrieval in the quality control of membrane protein complexes? Does the cell regulate other steps of membrane trafficking to control the number and type of ion channels and transmitter receptors? We have developed new methods to test the hypothesis that the numbers of different potassium channels are subjected to different membrane trafficking regulations. The examples to be used in our study are potassium channels that mediate slow synaptic potentials, control neuronal excitability, and potentially protect central neurons under stress. Mutations of potassium channel proteins are known to cause ataxia, epilepsy, deafness, arrhythmia, hypertension, and unchecked insulin release leading to hypoglycemia. Indeed, human epilepsy could result from mutations that reduce the M-type potassium channel activity by only 25 percent. And some of the disease-causing mutations alter the amount of functional potassium channels on the cell membrane. Our goal is to achieve better understanding as to how membrane trafficking regulates channel number and type. This may help us appreciate in the long run how regulation of membrane trafficking might contribute to synaptic plasticity, and whether malfunctions of this process contribute to mental and neurological diseases.

Project Title: MINK-RELATED PEPTIDES(MIRPS): STRUCTURE AND FUNCTION Principal Investigator & Institution: Goldstein, Steve a N.; Professor and Chief; Pediatrics; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2001; Project Start 01-AUG-1996; Project End 31-JUL-2005 Summary: MinK is a small ion channel subunit with a single transmembrane span. It is active only after assembly with a pore-forming subunit. Nonetheless, MinK is required for normal channel function in some tissues. Last period we learned why: MinK determines the gating kinetics, unitary conductance, ion selectivity, regulation and pharmacology of these mixed channel complexes. In the heart and ear, Mink assembles with KCNQ1 to form Iks channels. Inherited Mink mutations are associated with altered IKs function, cardiac arrhythmia and deafness. Mink was thought to be unique until last year when we cloned 3 genes encoding Mink-related peptides (MiRPs). In the last period, we studied the function, dysfunction and structure/function of MinK. We learned how disease-associated mutations altered Mink function and identified residues critical for activity. This allowed isolation of the genes for MiRP1, MiRP2 and MIRP3.

61
We then found that MiRP1 assembled with the pore-forming subunit HERG to reconstitute attributes of cardiac IKr channels. This led to our identification of MIRP1 mutations associated with sporadic long QT syndrome (LQTS), a rare disorder that predisposes to sudden death. More significantly, we later discovered that a MiRP1 polymorphism present in approximately 1.6 percent of healthy individuals places this large group at risk for a common, life-threatening disorder: drug-induced LOTS. Our most recent studies reveal that MiRPs operate not only with KCNQ1 and HERG but also with classical voltage-gated potassium channel subunits throughout the body. The central goal of this application arises directly from our studies of Mink over the last five years: we seek to learn how M1RPs (including Mink) operate in normal and disease states. The four specific aims are designed to evaluate (1) newly identified native MiRPpartner complexes from skeletal muscle, heart and brain; (2) newly identified diseaseassociated mutants; (3) MiRP domains and residues that mediate channel function; and, (4) sites of contact in MiRP-partner complexes. We argue these small subunits merit intense scrutiny. First, they are important to normal physiology and disease pathogenesis. Second, they have potential to reveal mechanisms of ion channel function from a unique vantage point: a peptide intimate with (but not of) the pore-forming subunit.

Project Title: MOLECULAR BASIS OF MATERNALLY TRANSMITTED DEAFNESS Principal Investigator & Institution: Fischel-Ghodsian, Nathan; Professor of Pediatrics; Cedars-Sinai Medical Center Box 48750, 8700 Beverly Blvd Los Angeles, Ca 90048 Timing: Fiscal Year 2002; Project Start 01-MAR-1992; Project End 31-MAR-2006 Summary: (provided by applicant): The broad long term objectives of this research proposal are to elucidate the molecular basis of maternally inherited deafness, and globally to shed light on the mechanism(s) of phenotypic expression of pathogenic mitochondrial DNA mutations. The specific aims of this proposal mainly revolve around the identification and functional characterization of a nuclear gene that is responsible for modifying the clinical expression of the A1555G mitochondrial DNA mutation associated with hearing impairment in humans. The health-relatedness of these aims is to provide the basis for the rational design of therapeutic interventions to prevent, correct, or circumvent the clinical expression of maternally transmitted hearing impairment specifically and mitochondrial DNA diseases more generally. The experimental approach will focus on the identification of a modifier gene on chromosome 8 using genetic mapping and the analysis of candidate genes in the region. In parallel, genetic linkage and candidate gene analysis will be used to identify additional loci and genes that may be modifiers of the clinical phenotype. Once the chromosome 8 modifier gene has been identified, the gene and its functional pathway will be functionally characterized using expression studies, cellular localization, identification of proteins binding to the modifier, and binding assays of both the mutated and non-mutated forms of the modifier protein.

Timing: Fiscal Year 2001; Project Start 01-APR-2000; Project End 31-MAR-2003 Summary: (Adapted from the Investigator's Abstract) Inner ear development has been described as one of the most remarkable displays of precision microengineering in the vertebrate body" (Swanson et al, 1990). The long term goal of this research is to examine the function of genes that shape very early events in inner ear development in order to understand the mechanisms that produce many severe forms of congenital deafness. The experiments in this proposal examine the functional role of two genes expressed early in the development of the auditory system: bone morphogenetic protein 4 (BMP4) and noggin. The first and second specific aims test the hypothesis that the morphogen BMP4 expressed in localized cell foci in the otic epithelium and the BMP4 antagonist, noggin, expressed in the surrounding periotic mesenchyme, are responsible for modeling the semicircular canals (SCC) and sensory tissue (hair cells) within them. The chick is used as the model system in these studies because the levels of these important molecules can be manipulated in the chick system and the effects of altering the environment on auditory system development can he assessed. These experiments cannot he done in the mouse or zebra fish because BMP "knockout" mice and zebra fish mutations die before the inner ear forms, and therefore, any effects of altering the levels of expression of these genes can not be assessed. These experiments depend on misexpression of BMP4 and noggin, by implanting agarose beads bearing cells that express noggin or BMP4 into ectopic locations in the early developing inner ear. Noggin bead implants eliminate SCC selectively; BMP4 implants "rescue" the lost canals. The third specific aim tests the hypothesis that BMP/I expression is critical for sensory cell (hair cell and supporting cell) development in the inner ear. This laboratory has produced BMP4 expressing immortalized otocyst cells from the 9 day Immortomouse. These cells were used to "rescue" the loss of SCC in the preliminary experiments on which these studies are based. The cells in culture not only express hair cell markers in the order expected for hair cells in the embryo, but also serve as a model system to study the role of the relevant genes in the production of hair cell/supporting cells in the inner ear. Furthermore, a BMP-4-expressing IMO cell line also produces the statoacoustic ganglion (SAG) neurite outgrowth/survival factor that directs the emerging neurites of the SAG back to BMFP-expressing sensory cell targets in the developing otocyst. IMO cell lines can therefore be used in molecular studies to identify the molecular cascades that produce sensory cell lineages as well as the SAG neurite outgrowth factor.

Project Title: MOLECULAR DEVELOPMENT OF THE ENDOLYMPHATIC DUCT AND SAC Principal Investigator & Institution: Choo, Daniel I.; Assistant Professor; Children's Hospital Med Ctr (Cincinnati) 3333 Burnet Ave Cincinnati, Oh 45229 Timing: Fiscal Year 2001; Project Start 02-APR-2001; Project End 31-MAR-2006 Summary: (from applicant's abstract): Homeostasis of inner ear endolymph is critical to sensory transduction in the inner ear. Failure to maintain endolymph homeostasis is thought to result in deafness, vestibular dysfunction and tinnitus in pathologies such as Meniere's disease or certain forms of hereditary hearing impairment. The endolymphatic duct and sac (ELDS) are key structures in maintaining this fluid homeostasis. Therefore, data on the molecular development of the ELDS are very relevant. By focusing on a mouse mutant (kreisler) with an ELDS phenotype, this application seeks to define the molecular pathways involved in induction and differentiation of the ELDS. To determine early targets of kr signaling, this application will test the hypothesis that expression of early molecular markers of the ELDS anlage is

down-regulated in homozygote kr embryos at embryonic day 10-11 compared to controls. The effects of kr mutation on cellular differentiation within the developing ELDS will be studied by testing the hypothesis that expression of a battery of genes specific for cells in the embryonic day 12 to 18 ELDS is down-regulated in kreisler homozygotes compared to controls. To facilitate direct experimental manipulation of the developing ELDS, this application will develop an in vitro model of the developing kreisler otocyst and ELDS. Experiments will first test the hypothesis that cultured kreisler otocysts developmentally mimic the in vivo system morphologically and functionally. This model will then be used to test the hypothesis that virally mediated expression of kr can rescue the ELDS phenotype in vitro. To test the hypothesis that hindbrain sources of kr induce ELDS differentiation, we will culture kreisler otocysts with wild-type hindbrain explants. Such data will provide insights into the molecular pathways involved in kr signaling and in development of the ELDS. The PI's obvious commitment to medicine and science has been demonstrated by his extensive pursuit of training in the clinical and basic science facets of inner ear biology. The success of these efforts are reflected in his publications which also demonstrate his ability to accomplish quality basic science investigation. In combination with the outstanding academic environment at Children's Hospital Research Foundation, the RCA will allow the PI to continue a rigorous scientific training and successfully address the specific aims outlined in the application. The proposed program of study and the science generated will undoubtedly advance the PI toward his goals of successfully competing for a future R01, and in the long term, becoming a successful independent Clinician scientist. Significantly, this proposal includes challenging but achievable goals that will provide important knowledge to the field of inner ear development.

Project Title: MOLECULAR DISSECTION OF MYOSIN VIIA Principal Investigator & Institution: Hasson, Tama W.; Biology; University of California San Diego 9500 Gilman Dr, Dept. 0934 La Jolla, Ca 92093 Timing: Fiscal Year 2001; Project Start 01-FEB-2001; Project End 31-JAN-2005 Summary: (applicant's description): The unconventional myosin, myosin-VIIa is critical for the development and function of the inner ear and for the maintenance and function of the retina. Mutations in myosin-VIIa result in Usher disease, characterized by profound deafness and retinal degeneration. Myosin-VIIa mutations also cause recessive and dominant deafness in humans and deafness in the mouse. Classically, myosins are described as motors that hydrolyze ATP and transport protein or organelle cargo along actin filaments. Various genetic and localization studies hypothesize that myosin-VIIa may act in protein transport, organelle movement, phagocytosis, endocytosis, or assembly of the inner ear actin cytoskeleton. Although this list is impressive, we don't actually know if myosin-VIIa is a motor and, significantly, no protein or organelle cargo have been identified. Our long term goal is to elucidate the function of myosin-VIIa in sensory cells and to identify the molecular cargo that this motor is transporting. Towards this aim, we will purify myosin-VIIa and investigate its mechanochemical properties using in vitro actin-binding, ATPase, and motility assays. We will use mutagenesis studies to characterize the effects of Usher disease mutations on myosin-VIIa enzyme function in vitro. To determine the molecular cargo of myosinVIIa, we will continue our analysis of three Myosin interacting Proteins, MYP6, MYP13 and MYP-kelch, which we identified as proteins that bind to the tail of myosin-VIIa. We will determine how these MYPs assemble with myosin-VIIa in vivo and also assess their roles in myosin-VIIa function. Ultimately we will ascertain whether binding of

molecular cargo directly affects myosin motility. To investigate the functions of myosinVIIa, we have identified two retina pigmented epithelium cell lines that recreate the expression of myosin-VIIa seen in vivo. Using transfection methods we will experimentally assess the hypotheses that myosin-VIIa functions in cytoskeletal assembly, phagocytosis, and membrane transport. Finally, we will extend upon our observation that myosin-VIIa is phosphorylated in vivo, by investigating the importance of this phosphorylation on myosin-VIIa function in the cultured retina lines.

Project Title: MOLECULAR GENETICS OF DEAFNESS IN THE AMES WALTZER MODEL Principal Investigator & Institution: Alagramam, Kumar N.; Pediatrics; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2006 Summary: (provided by applicant): We are interested in identifying and studying mammalian genes that are involved in auditory function and development of the neuroepithelia of the inner ear. The molecular analysis of hearing loss mutations in the mouse is an ideal way of gaining access to such genes. This proposal focuses on one particular mouse mutation called Ames Waltzer (av). The av is a recessive mutation, which causes deafness and vestibular dysfunction associated with degeneration of the inner ear neuroepithelia. We identified the gene that harbors the av mutation, Pcdh15 (Protocadherin 15). Sequence analysis showed that Pcdh15 is a novel member of the cadherin super family. We recently showed that mutation in the human homologue of mouse Pcdh15 causes Usher syndrome type 1F and thus, establishing av mouse as a model for deafness in USH1F. Protocadherins represent a large family of non-classic cadherins that are structurally and functionally divergent from the classic cadherins. In higher vertebrates, based on expression data, protocadherins are thought to be involved in a variety of functions, including neural development, neural circuit formation, and formation of the synapse. The role of protocadherins in the peripheral sensory apparatus, such as the inner ear, is unknown. Ames waltzer mice provide genetic evidence that a protocadherins is required for inner ear development and function. In the proposed study, we plan to determine the function of Pcdh15 in the normal development of the inner ear neuroepithelia. Specifically, we will study temporal and spatial expression patterns of Pcdh15 to understand the role of this gene in the normal structure and function of the inner ear. By using in situ hybridization and immunohistochemical methods, we plan to determine the primary site of action of the gene product during the course of inner ear development. We also plan to conduct detailed morphological analysis (using electron microscopy) to correlate ultrastructure and the nature of the mutation in the different alleles of av. Additionally, we also plan to identify proteins that interact with the protein encoded by Pcdh15. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

and expanding collection of genomic DNA from patients/families with non-syndromic deafness from China and Japan First, because of genetic heterogeneity, large multigenerational families and consanguineous families have been selected for study that are independently capable of yielding evidence of for linkage. We will then seek to identify and ultimately clone the relevant genes by the positional candidate gene approach. Second, a novel sequential screening strategy will be used to identify new genes for deafness in probands from multiplex families. Candidate genes to be screened will include the human orthologs of murine genes for deafness and other members of gene families in which some are known to be the cause of deafness. The research will yield important information o ethnic differences in the frequency and distribution of mutations at currently recognized genes for non-syndromic deafness. Using available information on outcome variables such as age of onset, audiologic findings, and the mating structure of the deaf population, these data will permit a search for clinically relevant genotype-phenotype correlations and a clearer understanding of the cause for secular changes in the frequency of specific forms o genetic deafness. Finally, we will use yeast 2-hybrid systems and the immunoaffinity chromatography to search for proteins that interact with the products of the MYO7A and USH1C genes. The identification of such interactions could lead to identifying potential modifiers and exciting new therapeutic approaches to attenuate the specific effects of mutations on the cochlear. The proposed work will identify the new gene (s) for non-syndromic deafness and enable us to understand better cellular and molecular basis of genetic deafness. Our studies will develop a more comprehensive picture of the involvement of genes in nonsyndromic deafness to gain further insight into the function of these genes in the inner ear. This knowledge is an essential prerequisite to the development and provision of molecular diagnostic services for families with non-syndromic deafness.

Project Title: MOLECULAR MECHANISMS IN HEREDITARY NEPHRITIS Principal Investigator & Institution: Hudson, Billy G.; Chairman; University of Kansas Medical Center Msn 1039 Kansas City, Ks 66160 Timing: Fiscal Year 2001; Project Start 01-JUN-2001; Project End 31-MAY-2002 Summary: Alport Syndrome is a hereditary disorder characterized by progressive nephropathy which is frequently associated with sensorineural deafness and ocular abnormalities. The nephropathy has been linked to a structural abnormality in the glomerular basement membrane (GBM) which is caused by mutations in the gene encoding the alpha3, alpha4 and alpha 5 chains of type IV collagen. The most common form is X-linked, in which over 200 mutations have been found in the COL4A5 gene encoding the alpha5 chain. These mutations interfere with the formation of the alpha3(IV)/alpha4(IV)/alpha5(IV) supramolecular network of type IV collagen. Most male patients have near normal kidney function at birth, which deteriorates over time leading to end-stage renal disease by mechanisms that are not understood. The central thrust of this proposal is to test the hypothesis that the progression to end-stage renal disease in X -linked hereditary nephritis evolves from a congenital malformation of the glomerular basement membrane (GBM) which involves COL4A5 mutations that arrest a developmental switch from the immature alpha1(IV)/alpha2(IV) network to the nature alpha3(IV)/alpha4(IV)/alpha5(IV) network, and the persistence of this immature network predisposes the GBM to proteolytic degradation. The cornerstone of the research plan is a use of the canine X-linked model of the human disease in which the COL4A5 gene mutation is a premature stop codon. The specific aims are: Aim 1: Determine the nature and timing of the switch from immature to mature GBM in
66
Deafness
normal dog kidney in comparison to affected male dogs. Aim 2: Determine which glomerular cells synthesize the alpha3(IV), alpha4(IV) chains. Aim 3: Examine the relationship between the expression of the alpha3(IV), alpha4(IV) and alpha5(IV) chains. Aim 4: Determine the temporal relationship at both the message nd protein levels of the expression of the alpha1(IV)-alpha6(IV) chains in normal dogs compared to affected male dogs during progression of their disease. Aim 5: Determine the susceptibility of type IV collage of GBM to proteolytic degradation in normal and affected male dogs. The achievement of these aims requires application of the techniques of molecular biology, biochemistry, immunochemistry and cell biology. It is anticipated that the achievement of the aims will yield new insights into the mechanisms underlying the pathogenesis of Alport Syndrome. An understanding of these mechanisms is fundamental to the development of therapeutic measures to correct the disorder by gene therapy or to delay progression to end stage renal disease.

Project Title: MOLECULAR MECHANISMS OF INNER EAR FUNCTION Principal Investigator & Institution: Heller, Stefan; Massachusetts Eye and Ear Infirmary 243 Charles St Boston, Ma 02114 Timing: Fiscal Year 2001; Project Start 01-SEP-2001; Project End 31-JUL-2006 Summary: Normal hearing and balance critically depend on the function of mechanosensitive receptors. In the inner ear, these receptors are involved in at least two fundamental processes, transduction by the hair cell stereocilia and regulation of the osmotic pressure of endolymphatic fluid in the scala media. We have recently identified an ion channel that is activated by exposure to osmotic stress and direct mechanical stimulation. This novel receptor, vanilloid receptor-related osmotically activated channel (VR-OAC), is expressed by inner ear hair cells and marginal cells of the stria vascularis. The Vroac gene is a positional candidate for the human deafness disorder DFNA25 and the deaf murine mutant Bronx Waltzer. We hypothesize that it is involved in mechano-reception by hair cells, measurement of the osmotic pressure of endolymphatic fluid, or both. Our long-term goal is to understand the physiological role of VR- OAC and its associated proteins in inner ear function. We will address this question through the parallel accomplishment of four specific aims. We have preliminary evidence that a second mechanoreceptive ion channel, related to VR-OAC, is expressed in the inner ear. We plan to search for additional VR-OAC-like channels (Aim 1). In Aim 2, we will determine the cellular and subcellular localization of VROAC and any other related channel that we identify in the inner ear via established methods of in situ hybridization and immunocytochemistry. Because our previous results implicate an essential interaction of VR-OAC with other intracellular proteins, we plan to identify these proteins utilizing the yeast two-hybrid screening system (Aim 3), an approach we have used previously to identify interaction partners of inner ear proteins. In Aim 4, we address the physiological relevance of heteromeric channels formed between VR-OAC and related channels, including the one we already have found. VR- OAC is currently the only mechanoreceptive ion channel that can be assessed by expression in a heterologous system, and we plan to physiologically characterize heteromultimeric channels using calcium imaging and whole cell recordings. We will also test VR- OAC's in vivo role by creating a mouse line carrying a null mutation. Phenotypic assessment of the resulting animals will provide fundamental clues as to the in vivo relevance of VR-OAC for inner ear mechanosensation, or osmoregulation, or both.

Project Title: MOUSE DEAFNESS AND STUDY OF A MOUSE DEAFNESS GENE Principal Investigator & Institution: Kohrman, David C.; Assistant Professor; Otolaryngology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2001; Project Start 01-APR-2001; Project End 31-MAR-2006 Summary: (Adapted from applicant's abstract): The primary objective of this proposal is the identification and characterization of the gene responsible for inherited deafness in the mouse mutant known as 'spinner'. Mutation of this gene results in sensorineural hearing loss similar to that found in many human nonsyndromic deafness disorders. The approaches described will attempt to correlate effects at the single gene level with those occurring at the cellular level and the level of the intact cochlea. A positional cloning strategy will be used to identify the affected gene. Gene localization information will be derived from an existing high resolution genetic cross and a set of genomic DNA clones that span the candidate region. Positional candidate genes mapped to this region in mouse, and to the region of conserved linkage in humans, will be evaluated for mutation in spinner mice. To further narrow the candidate region, genomic DNA clones from the candidate region will be microinjected into sr/sr zygotes. DNA clones that contain a functional version of the normal gene are expected to produce phenotypic correction in the resulting transgenic progeny. This DNA will be directly screened for the presence of the affected gene. The biological role of the spinner gene in the cochlea will be examined using several approaches. High resolution phenotypic analysis of affected mice will be performed to identify early defects in the cochlea that result from mutation of the spinner gene. Sensory cell function in the cochlea will be assessed by measurement of evoked responses in spinner mice. Ultrastructural and immunocytochemical analyses will be performed to detail the degenerative process in the mutant cochlea. Database analysis of the gene's primary sequence will be used to identify related genes and protein motifs that may provide insight into gene function. The expression pattern of the spinner gene, and the subcellular localization of its encoded protein, will be determined. Based upon comparative genetic data, the human version of the spinner gene is a positional candidate for the gene affected in a nonsyndromic deafness disorder, DFNB6. The human gene will be directly evaluated for mutations in individuals with inherited defects at the DFNB6 locus. This project will result in the identification of a critical gene in the mammalian inner ear, provide the basis for a model of this gene's role in the cochlea, and investigate the involvement of the gene in human nonsyndromic hearing loss.

Project Title: MURINE MODELS OF HYPOTHYROIDISM AND CONGENITAL DEAFNESS Principal Investigator & Institution: Walsh, Edward J.; Professor; Director; Boys Town National Research Hospital 555 N 30Th St Omaha, Ne 68131 Timing: Fiscal Year 2001; Project Start 24-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): The overall, long-term goal of the research proposed in this application is to determine the anatomical and physiological basis of peripheral auditory anomalies associated with congenital hypothyroidism and to initiate an investigation into the molecular nature of associated deficits. In doing so, we hope to expand our understanding of thyroid hormone's role in the normal development of the inner ear and extend our understanding of the auditory consequences of hypothyroidism by considering the relative contribution that discrete inner ear tissues

and structures make in the pathogenesis of the disease. The Tshrhyt mutant mouse is ideally suited to meet the needs of the proposed research and will serve as the primary model of hypothyroidism in the proposed study. We also propose to study normal BALB/c mice rendered hypothyroid through the actions of the anti-thyroid drugs, propylthiouracil (PTU) and methimazole (MMI), in an effort to establish a model of hypothyroidism-induced otopathology that will allow us to clarify differences reported in the literature regarding the effects of thyroid hormone deficiency on the auditory periphery, as well as the capacity of thyroid hormone to restore function in diseased animals. The chief hypothesis being tested in this proposal is that abnormal cochlear amplification represents an enduring defect of hypothyroidism-induced otopathology and that normal passive transduction is acquired developmentally over a protracted time course. In that context, in addition to experiments designed to address the primary question directly using in vivo recordings (ABR, CM and DPOAE), as well as in vitro recordings from outer hair cells, we plan to study the morphological and the functional properties of the tectorial membrane, along with its chemical composition, to determine its role in the pathogenesis of the disease. The role of other passive aspects of transduction (e.g., endocochlear potential) will be assessed directly. We also plan to take the first step in a study aimed at determining the molecular and genetic basis of hypothyroidism, using RT-PCR and in situ hybridization to study the expression of transcripts that may affect the expression of cochlear amplification. Finally, we propose to explore the intriguing possibility that the efferent OC system may influence the development of peripheral auditory function. If the main hypotheses proposed here are affirmed, the existing model of auditory system pathology induced by hypothyroidism will be fundamentally revised.

Project Title: MYOSIN 15 GENETICS, PATHOLOGY AND THERAPEUTIC POTENTIAL Principal Investigator & Institution: Camper, Sally A.; Professor; Human Genetics; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2006 Summary: Hereditary inner ear disease is prevalent and has significant implications for quality of life. There is currently no available clinical cure for hereditary inner ear disease. The mouse serves as an ideal mammalian model for understanding genetic inner ear disease and for developing therapeutic measures. Mouse models have facilitated the discovery of genes that underlie hereditary disease in humans, have made it possible to study the role of these genes in inner ear development and function, and hold great promise as models for developing treatments for hereditary inner ear disease. This grant application builds on our discovery that mutations in the unconventional myosin gene, Myo15, are responsible for profound congenital deafness in humans with DFNB3 and in two spontaneous mouse mutants with profound recessive deafness, shaker 2 and shaker 2J. We propose to use these two mouse models of DFNB3 to establish the structure and functional properties of this large myosin, the requirement for expression in utero and early postnatal life, and the developmental basis for pathology in affected individuals. As each of these goals are accomplished we will move closer toward the ultimate objective of gene therapy for congenital deafness in children and expand our molecular understanding of the basic hearing process. In the first aim, we will rigorously test the long-term functional and structural outcome of the phenotypic correction of deafness in shaker 2 mice that we accomplished by

complementation with a BAC transgene. The second aim tests the hypothesis that MYOSIN XV-deficient hair cells fail to detach from the basement membrane during development, leading to cellular pathology. The third aim examines whether loss of Myo15 function is partially compensated by the function of other myosins. The fourth aim tests whether the unusual N-terminal third of the MYOXV protein is important for function using transgenic mice. Finally the feasibility of gene therapy for DFNB3 in newborns or young children will be assessed in the last aim using inducible expression of Myo15 transgenes in young, postnatal shaker 2 mice. Our investigative team has a track record for accomplishments resulting from cross disciplinary collaboration, which has brought expertise in otolaryngology and morphology together with expertise in molecular and developmental genetics. Our interdisciplinary approach is essential to fully exploit the animal models that will be the basis for developing and testing therapy for hereditary inner ear disease.

Project Title: MYOSIN-X: A NOVEL MYOSIN WITH PH DOMAINS Principal Investigator & Institution: Cheney, Richard E.; Assistant Professor; Cellular/Molecular Physiology; University of North Carolina Chapel Hill Office of Sponsored Research Chapel Hill, Nc 27599 Timing: Fiscal Year 2002; Project Start 01-JUN-1997; Project End 31-MAY-2007 Summary: Myosin-X is an unconventional myosin of the MyTH-FERM super class that is broadly expressed in vertebrate tissues. Although little is known about the functions of the MyTH-FERM myosins, mutations in one member of this group are the leading cause of hereditary deaf-blindness in children. We recently discovered that myosin-X undergoes a novel form of motility within filopodia, and we hypothesize that myosin-X is a component of a widespread but previously uncharacterized system for intracellular transport on actin-rich structures such as filopodia. Myosin-X also exhibits a remarkable localization to the tips of filopodia and overexpressing it leads to increased number and length of filopodia, suggesting that myosin-X functions in the largely unknown pathways regulating filopodial dynamics. Myosin-X also binds to integrins and one of its light chains is known to be dramatically down regulated in many tumors. Together these data strongly suggest that myosin-X and the novel form of motility associated with it play fundamental but largely unexplored roles in the basic cell biology underlying human health and disease. We propose to: I. Determine the fundamental properties, mechanisms, and regulation of this novel form of motility. II. Identify the structures and molecular cargo(s) transported by intrafilopodial motility. III. Use myosin-X as a marker to identify the components of a putative filopodial tip complex and determine if myosin-X is a component of signaling pathways that regulate filopodial dynamics. IV. Determine the functions of myosin-X in key cell biological processes such as phagocytosis, filopodial dynamics, and cell crawling. This research will determine the fundamental properties of a novel and previously uncharacterized form of motility that has critical implications for a host of important cell biological processes including integrin function, cell adhesion, filopodial dynamics, macrophage function, and nerve regrowth. The proposed research will thus answer critical questions about the basic cell biology underlying many human diseases including cancer, hereditary deafness, retinitis pigmentosa, and nerve injury.

Project Title: NICOTINIC RECEPTORS IN COCHLEAR HAIR CELL PHYSIOLOGY Principal Investigator & Institution: Fuchs, Paul A.; Professor; Otolaryn & Head & Neck Surgery; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2006 Summary: (provided by applicant) Recent years have seen important developments in the study of hearing, especially the emergence of molecular genetics to probe the underlying mechanisms of hearing loss. It is estimated that 1 in every 1,000 newborns is profoundly deaf, while nearly 1 in 20 has a significant hearing impairment. In more than half of these cases, the cause is genetic. As of February 2002, twenty-nine specific genes have been associated with different forms of nonsyndromic human deafness. In addition, many other gene products involved in normal cochlear function have been identified. The foreign collaborator (Elgoyhen) cloned and characterized two novel nicotinic receptor genes (alpha 9 and alpha 10) that are expressed in cochlear hair cells. Alpha 9 and 10 encode receptor proteins that mediate the effect of acetylcholine (ACh) released by efferent neurons onto cochlear hair cells. The Principal Investigator (Fuchs) showed that calcium entry through the ACh receptor leads to hair cell hyperpolarization, reducing transmitter release to cause a loss of tuning and sensitivity in the auditory nerve fibers. This FIRCA proposal brings together the expertise of the Fuchs and Elgoyhen laboratories to conduct a series of electrophysiological and molecular genetic experiments to elucidate the properties and function of these cholinergic receptors in hair cell physiology. The long-term goal of this proposal is to define the physiological role of the hair cell's cholinergic receptor. In addition, it is expected that the results obtained will contribute to our understanding of the role of efferent cholinergic input in the genesis and potential treatment of hearing impairment produced by loud sound or ototoxic drugs. The immediate aims of this application are three-fold: first, the pharmacological and physiological comparison of recombinant alpha9/alpha10 receptors expressed in Xenopus laevis oocytes with native cholinergic receptors of inner and outer hair cells in acute cochlear explants; second, the characterization of the ontogeny of cholinergic responses in inner hair cells and third, the physiological analysis of synaptic contacts onto inner and outer hair cells in mice with genetic modifications in the Acra9 gene, namely the alpha9 null mutant mouse and a knock-in mouse bearing a gain of function mutation. This research will be done primarily in Argentina at INGEBI (National Research Council) in collaboration with Ana Belen Elgoyhen as an extension of NIH grant #R01 DC01508.

We propose to apply methods from theoretical and clinical linguistics to produce detailed analyses of the phonological systems that underlie speech production by deaf children after cochlear implantation. These detailed linguistic analyses of sound segment inventories, constraints on sequencing, variation in phonetic realizations of morphemes, and

implementation of phonological rules will then be compared to both all phonological systems in general and the phonological systems of deaf children who use conventional hearing aids, children who have normal hearing, and fully developed English. Longitudinal analyses of the phonological systems of children who use cochlear implants will identify possible directions and extent of changes in those systems and provide information regarding constraints on changes over time. Subtypes of phonological systems, based on structural similarities, will be identified and related to speech perception abilities and demographic factors such as age at implantation and communication mode to identify specific factors that may affect how phonological systems are structured. This research project will thus address the critical question of how cochlear implants shape the ultimate linguistic systems of children who use them. Findings will provide valuable new empirical and theoretical information about phonological development, which should have important implications for device design, the development and implementation of new intervention programs, and choices in educational placement. Finally, the proposed project on phonological systems of deaf children following cochlear implantation will provide new insights into the ability of the human brain to adapt to electrical hearing as a catalyst for the development of structured linguistic systems underlying spoken language development.

Project Title: PORCINE SUBMAXILLARY MUCIN AND HUMAN NORRIN Principal Investigator & Institution: Hill, Robert L.; Professor and Chairman; Biochemistry; Duke University Durham, Nc 27706 Timing: Fiscal Year 2001; Project Start 01-SEP-1978; Project End 31-DEC-2002 Summary: The structure/function relationships of two related proteins will be examined. Porcine submaxillary mucin is a glycoprotein containing about 67 percent by weight carbohydrate. Mucins lubricate the respiratory, gastrointestinal and urogenital tracts and protect epithelial cells from dehydration and injury. Much of porcine submaxillary mucin structure has been elucidated, but not all, including how the monomeric mucin molecules assemble to form dimeric and multimeric mucins that are the mature, functional molecules. The half-cystines that form the inter- and intrachain disulfide bonds in dimers and multimers will be determined. Particular attention will be given to the structural motif CGLCG and its role in assembly of multimeric mucin. These studies will utilize site-directed mutagenesis and expression of mutant constructs in animal cells in culture. Similar studies will be performed with norrin, a 133 residue human protein that is defective in Norrie disease, an X-linked, recessive human neurological disorder characterized by blindness, deafness and mental retardation. This protein is very similar structurally to the domain in some mucins that forms disulfidelinked multimers. The half-cystines in norrin that form inter- and intrachain disulfide bonds will be determined by the same methods used with submaxillary mucin. Hopefully, these studies will reveal how the disulfide-rich domains in proteins in which they occur lead to oligomer formation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Summary: (provided by applicant): The primary objective of these studies is to test and develop pharmacologic agents to protect against noise-induced hearing loss (NIHL). The long-term objective is to develop agents for oral administration in clinical populations. The primary hypothesis is that pharmacologically optimizing the glutathione pathway will ameliorate or prevent NIHL and that this protection can be obtained by either injection or by oral administration of carefully selected glutathione enhancing agents. The secondary hypothesis is that noise exposure will alter the glutathione pathway as measured by the ratio of reduced to oxidized glutathione and the affiliated enzymes glutathione reductase (GR) and glutathione peroxidase (GSH-Px) during the first 6 hours of noise exposure and that these changes will correlate with the level of lipid peroxidation as measured by malondialdehyde (MDA) levels. The first specific aim is to determine the time course of any changes in the cochlear levels of reduced glutathione, and the ratio of reduced (GSH) vs. oxidized (GSSG) glutathione prior to noise exposure, and.5, 2, 4, and 6 hours after onset of noise exposure. This aim will be accomplished by measuring cochlear glutathione, both the reduced GSH and oxidized GSSG, in animals sacrificed at those times. The critical measures will be the reduced GSH, and the GSH/GSSG ratio, a measure of oxidative stress. The second specific aim is to determine the time course of any changes in cochlear GR and GSH-Px, critical enzymes of the glutathione anti-oxidant pathway, at those same times. The third specific aim is to determine the time course of changes in cochlear lipid peroxidation at those same times. The second and third aims will be accomplished by measuring GR, GSH-Px, and MDA, a marker for cell membrane oxidative damage, in animals sacrificed at those times. The fourth specific aim is to determine the efficacy of 3 putative otoprotective agents in reducing noise induced cochlear damage with auditory brainstem response thresholds and outer hair cell counts as primary measures. Protection efficacy will also be measured by GSH/GSSG, GR, GSH-Px, and MDA measures. The fifth specific aim is to compare the efficacy of these same agents orally administered to the IP administration, utilizing the same outcome measures. These studies should lay the basis for clinical trials of oral agents to prevent NIHL. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: PROTEIN IMPORT INTO YEAST MITOCHONDRIA Principal Investigator & Institution: Jensen, Robert E.; Associate Professor; Cell Biology and Anatomy; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2001; Project Start 01-JAN-1993; Project End 31-DEC-2004 Summary: (applicant's description): The long range goal of this research proposal is to understand how proteins of the mitochondrial inner membrane and intermembrane space mediate two events: translocation of proteins into the mitochondrial matrix, and protein sorting to the inner membrane. Mitochondria are essential organelles, whose function requires the import of hundreds of different proteins that are encoded in the nucleus, synthesized in the cytosol and imported into the organelle. Protein import is a multistep pathway which includes the binding of precursor proteins to surface receptors, translocation across one or both mitochondrial membranes, and folding and assembly of the imported protein inside the mitochondrion. To understand how these processes occur, we have isolated and are analyzing mutants in the yeast, Saccharomyces cerevisiae, that are defective in mitochondrial protein import. Many studies indicate that mitochondria in yeast import proteins into their mitochondria by a process virtually identical to the way mammalian mitochondria import proteins. Hence our studies with yeast will yield valuable information about mitochondria biogenesis in all organisms. Supporting this view, a human disease called Mohr-Tranebjaerg

syndrome, a neurodegenerative disease characterized by deafness, dystonia , mental retardation and blindness, has recently been shown to result from a defect in mitochondrial protein import. The human mutation is in a gene encoding a protein called DDP, homologous to the yeast Tim8 protein. We anticipate that our future studies will continue to provide insights into the normal functions of mitochondria and their relationships to human disease. We have recently shown that the mitochondrial inner membrane contains two translocation complexes: the TIM23 complex, which is required to translocate precursors across the inner membrane into the matrix and the TIM22 complex, which is required for the insertion of polytopic proteins into the inner membrane. Tim54p, Tim22p and Tim18p comprise the membrane subunits of the TIM22 complex. In this proposal, we ask several questions aimed at understanding the mechanism by which proteins are inserted into the inner membrane. (1) What other proteins comprise the TIM22 complex? (2) Does Tim18p play a direct role in import? (3) Does Tim54p play a docking role in the insertion process? (4) What is the precise pathway that proteins traverse during their import and insertion into the inner membrane? (5) Can inner membrane protein insertion be reconstituted using purified components?

Project Title: REGULATING DORSOVENTRAL POLARITY WITHIN THE INNER EAR Principal Investigator & Institution: Epstein, Douglas J.; Genetics; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2008 Summary: (provided by applicant): The auditory and vestibular structures of the inner ear mediate our senses of hearing and balance, respectively. Recent progress has been made in identifying some of the causes of hereditary forms of deafness and vestibular disease in humans; however, a detailed understanding of the genetic pathways coordinating inner ear development remains limited. By identifying the genetic networks regulating inner ear morphogenesis, our understanding of the association between otic development and disease should improve. The principal components for hearing (the cochlea) and balance (the semicircular canals, utricle and saccule) are formed from ventral and dorsal outgrowths, respectively, of a common bilateral structure, the otocyst. Organization of the inner ear into auditory and vestibular components is dependent on localized patterns of gene expression within the otic vesicle. Surrounding tissues are known to influence compartmentalization of the otic vesicle, yet the participating signals remain unclear. The notochord and floor plate are sources of the secreted protein Sonic hedgehog (Shh) that functions in both short and long range signaling events to promote growth and differentiation of progenitor cells in the ventral neural tube and paraxial structures. In the absence of Shh, ventral otic derivatives including the cochlear duct and cochleovestibular ganglia fail to develop. The origin of the inner ear defects in Shh -/- embryos can be attributed to alterations in the expression of a number of genes previously implicated in the specification of cochlear, neuronal and chondrogenic lineages. Although the effects of Shh signaling are detected in the otic epithelium, adjacent tissues including the periotic mesenchyme and neural tube are also targets of Shh action. This brings into question the relative contribution of Shh signaling in each of the tissues impacting on inner ear development. Experiments outlined in this proposal are aimed at elucidating the mechanism by which Shh specifies auditory cell fates in the ventral otocyst. The temporal and spatial requirements of Hedgehog (Hh) signaling in inner ear development will be addressed
74

by the conditional inactivation of Smoothened, an essential transducer of all Hh signals, in each of the tissues impacting on the otic vesicle. Experiments to identity the downstream effectors of Shh signaling in otic development are also proposed. Finally, despite preliminary insights into how auditory cell fates are specified, little is known of the extrinsic cues that establish vestibular (dorsal) structures in the otic vesicle. Introduction of specific pathway inhibitors into the dorsal otocyst using transgenic approaches as well as the assessment of mouse mutants in candidate dorsalizing factors should contribute towards our overall understanding of how polarity is established along the dorsoventral axis of the inner ear.

Project Title: REGULATION OF MICROTUBULES BY RHO GTPASES Principal Investigator & Institution: Gundersen, Gregg G.; Associate Professor; Anatomy and Cell Biology; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2001; Project Start 01-APR-2001; Project End 31-MAR-2005 Summary: (provided by applicant) Microtubules (MTs) are ubiquitous elements of the cytoskeleton that are essential for the generation of cellular asymmetry during development and differentiation. In undifferentiated cells, most MTs are highly dynamic, whereas in polarizing or differentiated cells, certain MTs become stabilized and organized into specific arrays that are necessary for supporting polarized cell function. In many cases, alterations in proteins that regulate the formation of these MT arrays result in disease. Thus, lissencephaly is caused by alterations in the Lisl protein, which affects dynein functions in cell division and polarity. The nonsyndromic deafness syndrome, DFNA1, is cause by mutations in human Dia, a protein we have found regulates microtubule stabilization in fibroblasts. Our overall goal in this project is to determine the molecular mechanisms controlling MT stabilization and polarization and to explore their significance for cell function using the simple model system of in vitro wound healing. We have found that there are two distinct molecular pathways that regulate MTs during cell polarization and migration into wounds. These pathways resemble those described in yeast, where they function to position the nucleus and spindle. This suggests that MT-based polarization pathways have been conserved from yeast to mammals. One pathway involves the stabilization of MT oriented toward the wound and is regulated by the small GTPase Rho and its downstream effector mDia. We will explore how mDia regulates MT stabilization during in vitro wound healing by identifying the domain(s) of mDia important for MT stabilization and by identifying downstream effectors of mDia. Human Dia is mutated in DFNA1, and we will test the possibility that the mutation in DFNA1 alters MT stabilization. The second -pathway involves the reorientation of the MT organizing center (MTOC) toward the leading edge of cells adjacent to the wound margin. We have found that MTOC reorientation is regulated by CDC42 and is controlled independently of MT stabilization. We will study dynein and other potential downstream effectors to understand how CDC42 regulates MTOC reorientation. Lisl protein interferes with dynein function when overexpressed and we will test whether Lis1 overexpression effects MTOC orientation. We will study whether inhibition of MT stabilization or MTOC reorientation interferes with the polarization of cells, the migration of the cells into the wound and other wound responses. These studies should establish the molecular pathways by which MTs are regulated in cells and will contribute to our understanding of how cell polarity is established by MTs in all eukaryotic cells. These studies will also contribute to our understand of the basic molecular pathways involved in wound responses and will help

Project Title: REORGANIZATION OF VISUAL FUNCTIONS AFTER EARLY DEAFNESS Principal Investigator & Institution: Bavelier, Daphne I.; Associate Professor; Brain and Cognitive Sciences; University of Rochester Orpa - Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2001; Project Start 01-FEB-2001; Project End 31-JAN-2006 Summary: (Adapted from Applicant's abstract): The goal of this research is to assess and separate the effect of deafness and of acquisition of a sign language on the organization of the visual system. Visual abilities in hearing individuals will be compared with those of deaf signers. To separately document the role of deafness from that of signing, deaf with minimal exposure to sign and hearing individuals who are native signers will also be included. Indeed, the existing literature indicates that deafness and acquisition of American Sign Language have different and separate effects on the reorganization of visual functions. The aspects of the visual system that have been modified will be first determined by comparing behavioral indices of visual processes in these four populations. Modifications in brain organization that accompany these behavioral differences will be then characterized with functional magnetic resonance imaging (fMRI). The existing literature indicates that congenital auditory deprivation is associated with specific enhancement of behavioral performance and neural activity in response to moving stimuli and visual stimuli in the periphery. Since this type of information is predominantly represented along the dorsal visual pathway, it has been proposed that early deafness affects predominantly the dorsal visual pathway. This work will test the hypothesis that dorsal visual functions are altered after early deafness, by studying and comparing motion processing and spatial localization in deaf and hearing. The contribution of deafness and signing will be separately assessed by looking at deaf with minimal signing experience and hearing who are native signers. The second goal of this work is to test whether plastic changes are indeed specific to the dorsal pathway as has been hypothesized in the literature or if plastic changes can be induced by early dearness or signing in the other main visual pathway, i.e. the ventral pathway. For that purpose, face processing and handshape processing will be compared in deaf and hearing as a function of their signing ability. These experiments will provide new information about which sub-systems within vision are most altered by early auditory deprivation and/or early acquisition of signs, and will help to characterize how these changes are implemented at the cortical level. Since these studies will determine the aspects of visual perception that are most likely to reorganize when the environment is altered early on, these results will also carry implications for the kind of training that would optimize visual and attentional skills in children.

Summary: This proposal requests continued support for a program of research on perlingually deaf children with cochlear implants. The long-term goal of the project is to assess the effect of cochlear implants (CIs) on the development of speech production and language. In particular, we will compare the speech and language abilities of CI users to those of hearing aid (HA) users to determine the potential benefits of implantation compared to HA use. We will also compare the performance of children implanted early (below age 3-4) to those implanted later in life, to investigate whether early implantation may limit the negative consequences of auditory deprivation in the development of language and speech production. We will also study the influence of communication mode on speech and language development by comparing the performance of users of oral communication with users of total communication. We also plan to assess whether the latest clinically available processing strategies will allow children to reach superior levels of speech and language development, compared to older stimulation strategies. Finally, the proposed studies will provide information that will improve our basic understanding about the relation between the development of speech perception and speech production and about the development of language in children receiving impoverished auditory input. These goals will be achieved by a longitudinal assessment and description of the speech production and language abilities of a large group of deaf children, and by more intensive studies that focus on a smaller number of subjects. The proposed research extends our earlier work on speech production in a number of new directions. Project I will study the acoustic and physiological characteristics of the speech of implanted children and normal-hearing control subjects. Project II will examine the acquisition of English phonology by implanted children. Project III will assess the longitudinal changes in speech intelligibility by children with CIs and control groups of profoundly deaf children with hearing aids. Finally, Project IV will investigate the language development of implanted children and compare their performance to unimplanted deaf controls and normal-hearing children. The four projects of the proposed research address the efficacy of CIs in facilitating the development of specific abilities that all children must acquire to develop spoken language: the ability to control the physiological mechanisms used in speech production, to organize speech sounds into a coherent phonological system, to produce intelligible speech, and to control the creative, meaningful aspects of language.

Project Title: SPONTANEOUS SIGN SYSTEMS IN FOUR CULTURES Principal Investigator & Institution: Goldin-Meadow, Susan J.; Irving B. Harris Professor of Psychology; Psychology; University of Chicago 5801 S Ellis Ave Chicago, Il 60637 Timing: Fiscal Year 2001; Project Start 01-SEP-1988; Project End 31-JUL-2006 Summary: (provided by applicant): What might it mean to say that language is innate or, alternatively, that language must be learned? This proposal attempts to articulate these questions in terms that lend themselves to experimental investigation, asking which aspects of language development are so over-determined that they will appear even under learning conditions that vary widely from the norm. The participants are deaf children whose hearing parents have not yet exposed them to sign language, and whose hearing losses are so profound as to preclude acquisition of spoken language. Despite their lack of an accessible conventional language model, these children do communicate, developing gesture systems that are structured in language-like ways. Moreover, Chinese deaf children of hearing parents develop the same gesture systems as their American counterparts, suggesting that the deaf children's gesture systems are resilient, not only to the absence of a conventional language model, but also to cultural

77
variation. Where do these deaf children's gesture systems come from? One candidate is the gestures hearing adults produce as they talk. Indeed, the gestures of Mandarin speakers are similar in type to those of English speakers. However, the gestures adults use when speaking languages typologically distinct from Mandarin and English - verbframed languages such as Spanish or Turkish - differ strikingly from the gestures used by speakers of satellite-framed languages such as English or Mandarin. These four cultures thus offer an opportunity to examine effects of hearing speakers' gestures on the gesture systems developed by deaf children. If deaf children in all four cultures develop gesture systems with the same structure despite differences in the gestures they see, the children themselves must be bringing strong biases to the communication situation. The project has four aims: (1) To describe how adult speakers of Spanish or Turkish gesture differently from adult speakers of Mandarin or English. (2) To determine whether gesture systems created by Spanish and Turkish deaf children of hearing parents are structured as are gesture systems created by Chinese and American deaf children despite differences in the gestural models they see. (3) To describe how Spanish, Turkish, Chinese and American hearing children use gestures differently from deaf children in these same cultures even though they see hearing adults using the same gestures. (4) To determine whether Spanish, Turkish, Chinese and American hearing adults, when asked to use gesture as their sole means of communication, produce gestures structured like the deaf child's.

Project Title: STIMULI PROMOTING SURVIVAL OF SPIRAL GANGLION NEURONS Principal Investigator & Institution: Green, Steven H.; Associate Professor; Biology; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2002; Project Start 01-MAY-1996; Project End 31-MAY-2007 Summary: Spiral ganglion neurons (SGNs) die gradually following the loss of hair cells by the process of apoptosis. Electrical stimulation promotes the survival of such deafferented SGNs in vivo, raising the possibility of using electrical stimulation to maintain survival of SGNs in deaf individuals - in effect allowing cochlear implants to replace the trophic as well as the sensory function of hair cells. Our first goal is to provide a detailed timecourse of the key molecular events characteristic of apoptosis during the death of SGNs following deafening and describe how these events are affected by electrical stimulation. Rats will be deafened using ototoxin to destroy the hair cells and, during the approximately 100 day period over which SGNs die, the levels, the phosphorylation state and the subcellular localization of key representative apoptosis regulators and mediators will be determined immunohistochemically and biochemically. This will reveal at what stage(s) in the apoptotic process the SGNs exist following loss of hair cells, thereby identifying the time during which potential therapies for preventing SGN death would be most successfully applied. The second goal is to test the hypothesis implied by our previous studies: depolarization recruits three distinct kinase systems that independently and additively promote SGN survival, acting in distinct cellular compartments and on distinct substrates. Cyclic AMPdependent protein kinase and Ca2+/calmodulin-dependent protein kinase (CaMK) II, appear to function in the cytoplasm and phosphorylate mitochondrial apoptotic regulators, with CaMKII doing so by an indirect route involving tyrosine kinases. CaMKIV functions in the nucleus, phosphorylating the transcription factor CREB. To test this hypothesis, a lentiviral vector will be used to introduce genes encoding activated protein kinase mutants or kinase inhibitor proteins into SGNs, with these
78
Deafness
proteins restricted to specific subcellular locations, e.g., mitochondria or nucleus, by means of physiological targeting sequences. For these studies, we use the system we have developed, in which SGNs are electrically stimulated or depolarized in vitro to maintain their survival. In parallel, we will infuse pharmacological inhibitors or activators of these kinase systems into the cochleae of hearing or deafened rats, or deafened rats with implanted stimulating electrodes. These experiments will determine the extent to which these intracellular signals promote survival in vivo and verify that they mediate the survival-promoting effect of electrical stimulation in vivo as they do in vitro.

Project Title: STRUCTURE AND DYNAMICS OF CONNEXIN26 GAP JUNCTIONS Principal Investigator & Institution: Sosinsky, Gina E.; Professor; Neurosciences; University of California San Diego 9500 Gilman Dr, Dept. 0934 La Jolla, Ca 92093 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2007 Summary: (provided by applicant): Gap junctions serve an essential role in the passage of molecules from the cytoplasm of one cell to its neighbor in both functional and homeostatic capabilities. They are defined as clusters of closely packed intercellular membrane channels embedded in the plasma membranes of two adjoining cells. The channels are composed of two hexamers of a protein (connexon) from a family of integral membrane proteins known as connexins. Here, we focus on the structure and function of connexin26 (Cx26), the smallest of the family. Mutations in the DNA sequence can result in hereditary sensorineural deafness and account for between one third to one half of the cases of prelingual inherited deafness in Caucasian populations. We have isolated preparations of Cx26 gap junctions in pure and sufficient amounts for biochemical and structural studies. These 2D crystals are amenable to electron microscopy (EM) structure determination and conformational dynamics as revealed with atomic force microscopy (AFM) done under hydrated conditions. In SPECIFIC AIM 1, we will determine the structure of the Cx26 hemichannel beyond 10 Angstroms using state of the art cryo-EM and improvements on image processing procedures. This involves improving specimen preparation, imaging at either liquid nitrogen or liquid helium temperature and implementation of a combined single particle/ 2D crystallographic approach to circumvent imperfect crystal lattices. In SPECIFIC AIM 2, we will construct Cx26 wild type and mutant cell lines with a tetracysteine domain genetic tag to improve isolation with FlAsH ligand affinity bead purification, stably express these in HeLa cells or in baculovirus-infected Sf9 insect cells and isolate the gap junctions or connexons for structural analysis using the methods developed in Specific Aim 1. We will construct two Cx26 mutants (P97L and T135A), each containing a single point mutation in one of the transmembrane helices that changes the effective pore properties. These mutations should be reflected in conformational changes in the 3D structure. In SPECIFIC AIM 3, we will expand coordinated AFM/EM experiments for visualizing conformational changes due to treatments known to close or alter gap junction mediated communication. Preliminary AFM images have visualized conformational changes at submolecular resolution. We have chosen five treatments that known to induce closure of Cx26 channels or hemichannels and are physiologically relevant. Conformational changes identified by AFM imaging will be further imaged using EM. Each of these goals is intended to complement the others and lead to structural and physiological models of Cx26 germane to the entire connexin family.

Project Title: STRUCTURE OF DECODING SITE AND TELOMERASE RNA DOMAINS Principal Investigator & Institution: Rechkoblit, Olga A.; Sloan-Kettering Institute for Cancer Res New York, Ny 10021 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2005 Summary: (provided by applicant): RNA and RNA-protein interactions play a key role in many biological processes and diseases. Although, the majority of drugs target cellular, bacterial or viral proteins known to be associated with a particular human disease, some already existing highly efficient medications interact with RNA or RNAprotein complexes. A better understanding of RNA structure would provide access to design and optimization of new drugs targeting RNA. The emphasis of my research proposal is on the X-ray crystallographic determination of key RNA structures and their complexes. The proposal is subdivided into two major projects: antibiotic-human mitochondrial ribosomal decoding site recognition, and structure of the key domains of human telomerase RNA. The goal of the first project is to evaluate the structures of human mitochondrial ribosomal decoding site and aminoglycoside antibiotics induced deafness-associated mutant, both alone and in a complex with aminoglycosides. The available structural literature is focused on the prokaryotic decoding site and its complexes. The goal of the second project is to solve the structure of four crucial domains of human telomerase RNA and congenital dyskeratosis syndrome-associated mutants that, if successful, could provide deep insights into telomerase structure and function.

Project Title: STRUCTURE/FUNCTION ANALYSIS OF LOW PL CONNEXIN ISOFORMS Principal Investigator & Institution: Hertzberg, Elliot L.; Professor; Neuroscience; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2004 Summary: (provided by applicant): Gap junctions are assemblages of cell-cell channels occurring in regions of cell contact. These channels permit direct intercellular communication by passive diffusion of low molecular weight hydrophilic molecules, including calcium, cyclic nucleotides, inositol phosphates and other signaling molecules. Several gap junction proteins, termed connexins, serve prominent roles in the nervous system. Among these, Connexin43 (Cx43) is expressed at high levels in astrocytes where they provide a mechanism of spatial buffering of ions and exert a modulatory influence on neuronal activity. Mutations of Cx32, found in myelin, lead to a progressive peripheral neuropathy termed X-linked Charcot-Marie-Tooth disease. Mutations in Cx26 underlie the most common forms of non-syndromic deafness. Interestingly, connexins are the only family of plasma membrane proteins that do not appear to be glycosylated. Preliminary studies of Cxs 43, 32 and 26 indicate that they are significantly more negatively charged than anticipated based upon their sequence and known covalent modifications. That these pI variants are indistinguishable by SDS-PAGE indicates that the molecular basis for acidic pI variants is of low molecular weight. The specific aims of this proposal are to (1) identify this modification and the altered amino acid residues and (2) determine its role in the assembly and functioning of gap junction channels. Our approach to determining the chemical basis of connexin will be biochemical, relying especially on mass spectrometry, and genetic engineering. The role of this modification will be assessed using pharmacology and site-direct mutagenesis.

Identification of a low Mr anion covalently attached to connexins might provide the first target for pharmacological intervention in gap junction function. Knowledge of where charged residues exist will profoundly influence modeling studies of connexins and, likely, other membrane proteins, in which alterations of electrostatic interactions play a role in channel selectivity and gating. Many of the experiments will push experimental procedures for use in the study of membrane proteins. Establishing the basis of connexin charge alteration will introduce a new player in chemical modification of proteins and their properties.

Project Title: STRUCTURE/FUNCTION STUDIES OF GAP JUNCTIONS Principal Investigator & Institution: Bargiello, Thaddeus A.; Neuroscience; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2001; Project Start 01-FEB-1992; Project End 31-JUL-2004 Summary: Gap junctions formed by Cx26 and Cx32 differ in molecular permeability and in sensitivity to transjunctional voltage. These differences will be exploited to define the molecular mechanisms that underlie voltage dependence and ionic fluxes of intercellular and membrane channels formed by proteins of the connexin gene family. In the long term, integration of data from biophysical, molecular genetic, NMR and computer modeling studies will lead to understanding of how conformational changes in this membrane protein and others dynamically relate to their function and how fixed charges modulate ion flux. In the proposed studies the pore-lining sequence of the Cx32 channel will be further defined and the atomic structure of the amino terminus of wild type and mutated Cx32 will be solved by high resolution NMR. The position of the voltage sensor and its relation to the transjunctional electric field will be explored. Studies are proposed to test the hypothesis that the conformational flexibility of a proline kink motif underlies the conformational changes required for voltage dependent gating. Studies are also proposed to distinguish between concerted and individual subunit gating models. Data from molecular and electrophysiological studies of ionic flux will be examined using the electrodiffusive model of Chen and Eisenberg to further define the roles of charged amino acids in determining permeation and selectivity of gap junction channels. X-linked Charcot-Marie-Tooth disease (CMTX) is caused by mutations of human Cx32, and nonsyndromic deafness by mutations of Cx26. Biophysical and molecular studies have shown that changes in permeability of Cx32 are likely to underlie the etiology of CMTX. The proposed studies will advance the basic scientific knowledge required to define the molecular basis of this and other connexinrelated diseases, and the biological role of gap junctions.

The mouse is an excellent animal model for the study of these human conditions because the anatomy, function and hereditary abnormalities of the ear have been shown to be similar in both humans and mice. We

have recently described one such model resulting from a spontaneous mutation in a C3HIHeJ colony of mice at the Jackson Laboratory. The insertion of a retrotransposon (intracisternal A particle) into an intron of Eyal was associated with reduced expression of the normal Eya] message and inner ear and kidney abnormalities. We have designated this mutation Eya1 bor The human homologue of this gene, EYAJ, has been shown to underlie Branchio-Oto-Renal (B OR) syndrome, an autosomal dominant disorder characterized by hearing loss with associated branchial and renal anomalies. The function of this new class of nuclear protein is poorly understood. Our preliminary data, and that of our collaborators, suggests a critical role for this gene, and other members of this gene family (Eyal-4), in inner ear morphogenesis and postnatal function. In this proposal we intend to explore the hypothesis that Eyal participates in a regulatory network, as Jescribed in the Drosophila eye (eya), that is conserved and critical, in a dose dependent manner, to the early inductive events in mammalian ear development and maintenance of the mature auditory phenotype. We will examine the dose dependent effects on the ear and related structures, in viva, anatomically, functionally and molecularly. This will be accomplished by studying the Fl mice resulting from a cross between C3H/HeJ Eyalb0r/+ and BALB/cJ Eya1+/- and Eyal over-expression transgenic mutants. Additionally, we will identify the regions of the Eya homologous region (EyaHR) that are critical to the protein-protein interactions with other members of this conserved transcriptional regulatory complex. These and future experiments represent the natural progression from my Mentored Clinical Scientist Development Award (K08). Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: THE ZEBRAFISH EAR Principal Investigator & Institution: Malicki, Jarema; Assistant Professor; Massachusetts Eye and Ear Infirmary 243 Charles St Boston, Ma 02114 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 31-MAY-2005 Summary: (Investigator's abstract) The long-term goals are to identify in the sensory epithelia of the zebrafish. The identification of genetic mechanisms involved in the generation and regeneration of hair cells is potentially of great practical importance because the components of these mechanisms may be used to trigger hair cell regeneration in the human auditory system. Understanding the genetics of hair cell maintenance might lead to new treatment regimens for progressive hearing loss. The small quantities of tissue available from the vertebrate inner ear constrain the understanding of the molecular biology of the inner ear to genes expressed in high quantity or to those affected in naturally occurring mutations in (primarily) man and mouse. Zebrafish forward genetic analysis, through random mutagenesis approaches, provides an opportunity to find genes that may be critical, but expressed in very small quantities. Although the mammalian inner ear is more complex than that of the fish, the fundamental elements of inner ear function appear to be the same in both. To identify such genes, we propose to screen for recessive deafness in chemically mutagenized fish using F2 parthenogenetic diploids. The specific aims are: (1) to use chemical mutagenesis and early pressure to generate parthenogenetic diploid embryos from the progeny of mutangenized fish; (2) to search for defects in hair cell generation, regeneration, function, and maintenance by screening for morphological defects in inner ear structures in early larvae; for balance problems in larvae; for defects in hair cell generation in the lateral line organ with a hair cell selective fluorescent dye (daspei); for defects in hair cell regeneration after neomycin induced destruction of hair cells, and for functional defects in hearing at day 7 and at 3 months with an automated behavioral

Project Title: THYROID HORMONE RECEPTORS AND GENETIC CONTROL OF HEARING Principal Investigator & Institution: Forrest, Douglas; Assistant Professor; Human Genetics; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2002; Project Start 01-AUG-1997; Project End 31-JUL-2007 Summary: (provided by applicant): Thyroid hormone is essential for the development of hearing and inadequate hormone levels at early stages of development lead to profound deafness. Although the need for thyroid hormone is well known, less is understood of how it acts and what it controls in the development of the auditory system.Thyroid hormone receptors in target tissues transmit the hormonal signal into cellular responses. The study of these receptors is therefore expected to reveal critical steps in the chain of events that control the development of the auditory system. A primary site of action of these receptors in the auditory system is in the cochlea.Thyroid hormone receptors act as hormone-activated transcription factors and are encoded by two related genes, Thra and Thrb. Targeted mutagenesis in mice indicates that Thrb has the primary role and Thra a lesser role in the control of cochlear development. The mutant phenotypes indicate that thyroid hormone receptors regulate relatively late stages of maturation of the cochlea prior to the onset of auditory function.This renewal application aims to advance our understanding of the role of these receptors in cochlear -development by investigation of: 1) The role of thyroid hormone-metabolizing enzymes (deiodinases) as regulators of thyroid hormone receptor function in the cochlea; 2) The developmental signals that induce Thrb gene expression in the cochlea; 3) A novel gene that was identified using Thrb-null mice to screen for genes involved in the maturational stages of cochlear development. This gene expresses a novel extracellular matrix protein in the cochlear basilar membrane. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: TISSUE ENGINEERING OF THE INNER EAR Principal Investigator & Institution: Miller, Josef M.; Professor & Director of Research; Otolaryngology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2001; Project Start 01-APR-2000; Project End 31-MAR-2003 Summary: Three critical findings have been made over the last several years with important implications to the treatment of the deafened auditory system. First, there are significant changes to the peripheral auditory system as a consequence of deafness in the adult animal. Second, these changes impact on the reintroduction of input after deafness. Third, it is now possible to intervene and influence deafness-related changes to permit optimal processing of re-introduced input. Such interventions can be termed "Tissue Engineering" and their basis development, and application drive our proposed studies. A great deal of our current knowledge regarding interventions that may effect the survival and function of the sensory nerves derives from in vitro studies of cells in culture and organotypic preparations. The goal of this investigation is to verify the validity of these interventions in vivo, and to test the efficacy and safety of potential

interventions to "engineer" the tissues of the inner ear in vivo. Our first specific aim is to test the utility and synergy of chemical and activity factors involved in the survival of the auditory nerve for enhanced spiral ganglion survival after deafness. We hypothesize that there are naturally multiple factors involved in the maintenance of spiral ganglion cells, which not only provides redundancy (for increased protection) but also synergy in effect, and we can achieve maximal enhancement with multiple factors. Our second set of studies how neurotrophic factors and stimulation induced activity can not only enhance spiral ganglion cell survival but also induce regrowth of auditory nerve peripheral process, which regress after inner hair cell loss. Our ultimate goal is to develop the knowledge base and the tools to intervene in and influence the deafened auditory system to provide the best possible environment for re-introduction of auditory information. Hopefully, these in vivo studies will provide a critical step in the transfer of this technology to human application. The interventions that are developed will provide the substrate essential for reconnecting regenerated hair cells in the future. The should directly enhance the benefit of cochlear prostheses at present. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: TRANSDUCTION MECHANISM OF HAIR CELLS Principal Investigator & Institution: Hudspeth, Albert J.; Professor; Lab of Sensory Neuroscience; Rockefeller University New York, Ny 100216399 Timing: Fiscal Year 2002; Project Start 01-JUL-1983; Project End 31-MAR-2007 Summary: Hair cells are the sensory receptors of the internal ear, where they underlie the responsiveness of both the auditory and the vestibular systems. Each hair cell is a mechanoreceptor that responds when a sound or an acceleration applies a force to its hair bundle, a cluster of a few dozen to a few hundred mechanically sensitive filaments protruding from the cell's top surface. Because most hearing loss and many forms of dysequilibrium result from damage to hair cells, the proposed experiments are meant to reveal more about how these cells perform their essential functions. First, a combination of electron-microscopic and biophysical experiments will be used to determine whether a hair cell adapts to a prolonged stimulus by physically resetting the molecular apparatus in its hair bundle. The proposed experiments should show whether the myosin molecules thought to mediate adaptation occur at the appropriate sites and whether these molecules actually move as the hair cell adapts. A second set of experiments is meant to determine whether the hair bundle helps amplify the ear's mechanical inputs, thus augmenting the sensitivity of hearing and sharpening its frequency discrimination. In addition to providing information about the nature of the ear's amplificatory process, this investigation may indicate why hearing is vulnerable to overstimulation and whether the ear's amplifier can be protected from or regenerated after injury. In a final set of studies, genetic and molecular- biological techniques will be used to identify proteins essential to hearing and balance. More than a hundred genes are involved in heritable forms of deafness and vertigo, which affect one child in a thousand at birth and a similar proportion later in life. The zebrafish, a tractable model organism suitable for large-scale genetic analysis, will be used to identify novel genes and to determine the functions of recently discovered genes in the inner ear. After the corresponding human genes have been found, their roles in the ear and their possible involvement in human hearing loss and dysequilibrium will be examined.

Project Title: VACCINATION FOR LASSA FEVER Principal Investigator & Institution: Buchmeier, Michael J.; Professor; Scripps Research Institute 10550 N Torrey Pines Rd La Jolla, Ca 920371000 Timing: Fiscal Year 2002; Project Start 01-JAN-2002; Project End 31-DEC-2005 Summary: (Provided by Applicant) Lassa virus, endemic in West Africa, infects 100,000300,000 people annually, killing 5,000-10,000, and leaving about 30,000 with residual sequelae such as nerve deafness. The overall goal of this grant proposal is to understand the protective immune response to Lassa virus, thus positioning us to develop a vaccine against Lassa fever. Lassa virus is a Biosafety level 4 (BSL4) agent, and the constraints imposed by this fact have significantly impeded our ability to study the agent. Nevertheless, vaccine studies were carried out almost a decade ago, in guinea pigs and primates, and showed clearly that protective immunity could be conferred against this disease. However, the protective component(s) of vaccine-induced immunity were not identified. We are now in a much stronger position to evaluate the protective components, and shall do so in the experiments we propose. Our group has extensive experience with emerging viruses in general, and Lassa virus in particular. In addition we have many years of experience in designing vaccines against Old World arenaviruses. The constructs we will use will exploit recent advances that greatly enhance the immune responses induced by DNA vaccines, optimizing the induction of T cells (CD8+ and CD4+), and antibodies. There are only two reliable challenge models for Lassa fever, guinea pigs and primates. The Scripps collaborators will first evaluate the immunogenicity of the vaccines in guinea pigs with immunized animals also being sent to USAMRIID for live virus challenge trials. In the second year the study will then move to the primate models in Houston, where we will use rhesus macaques (Indian origin) characterized in the MAMU I allele in order to evaluate the immune response in primates in a model that closely parallels the human responses to the same viral antigens. Finally the vaccinated monkeys will be moved to USAMRIID where challenge studies will be performed under the supervision of Dr. Peter B. Jahrling, and where all the collaborators will combine efforts on site to ensure an exhaustive evaluation of the responses of the individual primates. These studies are expected to lead to the identification of a candidate Lassa vaccine that can be tested in humans. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

CHAPTER 2. NUTRITION AND DEAFNESS Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and deafness.
Finding Nutrition Studies on Deafness The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “deafness” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. CLINICAL TRIALS AND DEAFNESS Overview In this chapter, we will show you how to keep informed of the latest clinical trials concerning deafness.
Recent Trials on Deafness The following is a list of recent trials dedicated to deafness.8 Further information on a trial is available at the Web site indicated. •
Genetic Studies of Tone Deafness Condition(s): Healthy; Tone Deafness Study Status: This study is currently recruiting patients. Sponsor(s): National Institute on Deafness and Other Communication Disorders (NIDCD) Purpose - Excerpt: This study will examine the hereditary basis of tone deafness by identifying regions of the human genome linked to this condition. Both exceptionally good pitch recognition (perfect pitch) and exceptionally poor pitch recognition (tone deafness) run in families. A better understanding of what causes tone deafness may provide new insights into auditory (hearing) function. Individuals with two or more family members 15 years of age or older who are tone deaf or have trouble recognizing different melodies may be eligible for this study. Candidates will be screened with a short listening test for pitch and a short written test. Those identified with poor pitch recognition will fill out a brief questionnaire about their family tree and family members (without identifying names) who have trouble recognizing melodies or tones. Individuals with poor pitch recognition will be asked to help contact family members who may be interested in participating. Members of families with two or more firstdegree relatives (parents, grandparents, siblings) who are tone deaf may enroll in the study. They will provide a blood sample (about 2 tablespoons) for genetic studies and may take a 20-minute hearing test using headphones. Study Type: Observational

Keeping Current on Clinical Trials The U.S. National Institutes of Health, through the National Library of Medicine, has developed ClinicalTrials.gov to provide current information about clinical research across the broadest number of diseases and conditions. The site was launched in February 2000 and currently contains approximately 5,700 clinical studies in over 59,000 locations worldwide, with most studies being conducted in the United States. ClinicalTrials.gov receives about 2 million hits per month and hosts approximately 5,400 visitors daily. To access this database, simply go to the Web site at http://www.clinicaltrials.gov/ and search by “deafness” (or synonyms). While ClinicalTrials.gov is the most comprehensive listing of NIH-supported clinical trials available, not all trials are in the database.

CHAPTER 6. PATENTS ON DEAFNESS Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “deafness” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on deafness, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Deafness By performing a patent search focusing on deafness, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We

will tell you how to obtain this information later in the chapter. The following is an example of the type of information that you can expect to obtain from a patent search on deafness: •
Apparatus for use in conjunction with lipreading by the profoundly deaf Inventor(s): Fourcin; Adrian J. (London, GB2), Rosen; Stuart M. (London, GB2), Walliker; John R. (Epsom, GB2) Assignee(s): National Research Development Corporation (London, GB2) Patent Number: 4,809,329 Date filed: August 29, 1986 Abstract: The profoundly deaf benefit in lipreading if the larynx frequencies of speech are presented to them by means of acoustic sine waves. In the present invention the sine waves required are generated using a microcomputer and analogue output circuits, with the microcomputer providing digital level samples for the required sine waves from a stored look-up table. The wide frequency range of sine waves required is achieved by omitting some samples in each cycle at high frequencies, and the wide range of output levels required is provided by employing two digital to analogue converters, one acting as an attenuator. Excerpt(s): The present invention relates to apparatus which generates an audio signal from speech and which is of assistance to the profoundly deaf when lipreading. As mentioned in "Speech Pattern Element Stimulation in Electrical Hearing" by Adrian Fourcin, Ellis Douek, Brian Moore, Evelyn Abberton, Stuart Rosen and John Walliker, Archives of Otolaryngology, Vol. 110, March 1984, the profoundly deaf may be assisted in lipreading if larynx frequency information is presented to them acoustically in pure sine wave form. The explanation for this finding is not certain, but may be that a sinusoid is the only waveform which can pass through a dispersive linear filter (transducer, ear canal, tympanic membrane, ossicular chain [if present], cochlea) and still retain its overall shape. A major problem which is encountered in producing the required sine wave output is the generation of an accurate sine wave of varying amplitude over a frequency range from about 30 Hz to about 800 Hz.

Apparatus to alert a deaf person Inventor(s): Brugger; Richard D. (5433 Clinton Dr., Erie, PA 16509), Sulkoski; Jerome (7258 Bell Rd., Harborcreek, PA 16511) Assignee(s): none reported Patent Number: 4,380,759 Date filed: November 5, 1980 Abstract: An apparatus to alert a deaf person made up of an alarm device such as a smoke detector adapted to vibrate when actuated by smoke and a transmitter having a vibration sensor connected to the transmitter. The vibration sensor is supported in engagement with the smoke detector and adapted to sense the vibrations of the smoke detector and to transmit a signal to a remotely located receiver. The receiver has a vibrating reed with a tacticle member on its end for engaging a person to alert him when the receiver causes the reed to be vibrated.
Patents 149
Excerpt(s): Apparatus has been designed and assembled for the purpose of alerting a deaf person to certain specific dangers. One such danger is a fire, where he may be unable to hear the "audible" alarm that is characteristic of Smoke Alarms. This apparatus picks up the sound vibrations from the conventional Smoke Detector and causes a radio signal to be transmitted to a receiver and a "stimulator" located on the deaf person. A novel configuration of piezoelectric reed and special electronic circuitry is a part of this apparatus. The apparatus uses commercially available devices, generally, since the intent was to construct a working model and to create an overall system design. Also, it is less expensive and easier to make changes and modifications at this level than it would be to do those things after miniaturization is performed. The following patents are known to the inventer. U.S. Pat. Nos. 2,582,777; 3,618,070; 3,623,064; 3,786,628; 3,810,170; 3,911,416; 4,028,882 and 4,180,810.

Braille deaf-blind communicators Inventor(s): Fewell; William B. (124 Dow Rd., Port Charlotte, FL) Assignee(s): none reported Patent Number: 4,215,490 Date filed: November 16, 1977 Abstract: A hand held and portable device used for communicating between blind-deaf persons and between blind-deaf and nonhandicapped persons who know the Braille system. The transmitter person presses one or a number of the six keys in combinations producing raised projections representing a six unit Braille cell to be felt and read by a receiving person through tactile finger sensation. Excerpt(s): This invention has for an object to provide a portable means for communicating with a deaf-blind person who knows the Braille system. Also the apparatus may be used for communicating between two deaf-blind persons. Another object is to provide a simple means of communicating between handicapped persons having the use of only one hand and three fingers. A further object is to provide an apparatus which is small enough to be carried in the purse of pocket and be hand held when communicating. Web site: http://www.delphion.com/details?pn=US04215490__

Cochlear implant auditory prosthesis Inventor(s): Jacobs; Jared J. (14251 Paul Ave., Saratoga, CA 95070) Assignee(s): none reported Patent Number: 5,061,282 Date filed: October 10, 1989 Abstract: A cochlear implant auditory prosthesis corrects sensorineural deafness by generating stimulus signals to neurons connected to the auditory nerve in response to vibrations in the basilar membrane of the cochlea of the inner ear. The prosthesis comprises a plurality of transducer elements disposed along the length of the cochlea adjacent to the basilar membrane, whereby each transducer element responds to vibrations in the basilar membrane at the corresponding location of the respective
150 Deafness
transducer element. Each transducer element comprises a transducer for detecting the respective vibrations of the basilar membrane, and a signal processing element for generating a stimulus signal in response to the vibration. The frequency response and gain of each transducer element of the prosthesis can be tuned by a compact control unit to provide an ideal response for the user. Excerpt(s): The present invention relates to a cochlear implant prosthesis for individuals who have hearing disabilities. More specifically, this invention relates to a cochlear implant auditory prosthesis for generating stimulus signals to neurons connected to the auditory nerve in persons suffering from sensorineural deafness. The cochlea is a fluidfilled organ in the inner ear which aids in the conversion of sound waves to electrochemical stimuli. In a healthy ear, sound normally travels through the external ear canal to the tympanic membrane, also known as the ear drum. The tympanic membrane vibrates in response to pressure changes in the sound waves. The vibrations are transmitted through a series of small bones in the middle ear to the cochlea, or inner ear. The innermost of the small bones, the stapes or more commonly referred to as the stirrup, contacts a membranous opening known as the oval window at the base of the cochlea. The stapes transmits sound vibrations through the oval window to the fluidfilled interior of the cochlea. These sound vibrations are then transmitted through the cochlear fluid which induces vibration in a membrane within the cochlea. This membrane, known as the basilar membrane, follows a spiral path along the length of the cochlea. Longitudinal lines of hair cells on the basilar membrane sway in response to the vibrations. The motion of the cilia of the hair cells causes alternating localized changes in electrical potential that stimulate the auditory nerve fibers. A dysfunction of these hair cells causes sensorineural deafness, whereby the hair cells respond improperly and fail to stimulate the auditory neurons. Each auditory nerve fiber carries a specific modality of sensation to the brain. The type of sensation perceived when a sensory nerve is stimulated is determined by the specific area in the central nervous system to which the nerve fiber leads. Thus, regardless of whether the auditory nerve is stimulated by its sensory end-organ hair cell, or by direct electrical signals, a perception of sound is created. This phenomenon forms the fundamental basis of the implanted cochlear prosthesis. Web site: http://www.delphion.com/details?pn=US05061282__ •
Communication apparatus and method for performing vision testing on deaf and severely hearing-impaired individuals Inventor(s): Hutchinson; Ray Anthony (Olivenhain, CA) Assignee(s): Quo Vadis, Inc. (Encinitas, CA) Patent Number: 5,929,972 Date filed: January 14, 1998 Abstract: An apparatus and method for communicating to a deaf or severely hearing impaired individual while vision testing utilizing indicator lights (52A), (52B), (52C), and (52D) positioned in the same plane as a visual acuity test chart (54) having optotypes (50B). The examiner activates the indicator lights by means such as an infrared remote control receiver (56). This is done in a manner previously disclosed to the examinee permitting the examinee to understand messages from the examiner, while the examiner simultaneously operates a refractor to determine the refractive state of the examinee.
Patents 151
Excerpt(s): This invention relates to vision testing deaf or severely hearing-impaired individuals, specifically to the means by which the examiner communicates the necessary instructions to the hearing impaired individual during the course of the examination. The usual means of communicating to deaf and hearing-impaired individuals are through the printed word, sign language, finger spelling, lip reading, gestures or by touch. Except for touch, the hearing-impaired individual must be able to observe the one attempting the communication. Other means of non-verbal communication for the handicapped have been developed. U.S. Pat. No. 4,406,998 to Willough, Sep. 27, 1983 discloses a device which allows communication through lighted message blocks. Many devices have been developed which allow communication from a handicapped person to another, such as the apparatus disclosed in U.S. Pat. No. 3,651,512 to Summers, Mar. 21, 1972. A vision examination consists of many parts. Typically, an eye examination will include the patient case history, visual acuity testing, various eye health tests, muscle balance tests, objective refraction and subjective refraction. Visual acuity testing is accomplished using various types of visual acuity test targets and displays. A test distance between the patient and the test targets is typically twenty feet. Visual acuity test targets are known as optotypes. One such optotype is disclosed in U.S. Pat. No. 4,968,131 to Lewis, Nov. 6, 1990. Historically these test targets were presented to the patient as a wall chart having the optotypes imprinted on it. Currently, the most common method of presenting the optotypes to the patient is through the use of a chart projector which projects the optotypes upon a reflective screen. To permit adequate visualization of the projected acuity chart, the room is generally made dark. Alternative methods of displaying visual acuity charts have been developed. One such device is a translucent panel with imprinted optotypes which is rear-illuminated as disclosed in U.S. Pat. No. 5,129,720 to Jovicevic, Jul. 14, 1992. Another method employs a computer to generate optotypes upon a video display unit as disclosed in U.S. Pat. No. 4,239,351 to Williams, et al, Dec. 16, 1980. Testing of visual acuity and the use of optotypes is integral to the vision examination and is measured repeatedly during the subjective testing phase of the examination.

Communication device and method for deaf and mute persons Inventor(s): Butnaru; Hanan (1 Somerville Ct., San Antonio, TX 78257), Krueger; Wesley O. (4410 Medical Dr., Suite 340, San Antonio, TX 78229) Assignee(s): none reported Patent Number: 6,240,392 Date filed: August 29, 1997 Abstract: A communication device for deaf, hearing impaired, or mute persons comprises a processor control system which makes use of a microphone and a speech recognizer to receive and process audio data (speech or non-speech) to determine whether or not a dangerous situation exits within the environment surrounding the user. The system comprises a key pad and/or stylus and tablet information input system to accommodate communication from the user to the persons in the surrounding environments and a visual display capability to transmit the information so acquired by way of a projection apparatus in the form of characters and in the language to which the user is accustomed. Indicator signals which correspond to dangerous or cautionary situations relating to abnormally loud noises, or readily recognized sound patterns, such
152 Deafness
as a siren may also be displayed to the user, as may be information related geographic location, distance to a preset destination, or other personally useful information. Excerpt(s): This invention relates generally to a device for communication between persons who are deaf, hearing impaired, or mute. More particularly, the invention is directed toward a communication system for deaf, hearing impaired or mute persons which allows the user to visualize speech and other sounds directed at him through various audio sources. Historically, deaf, hearing impaired, and mute persons have had a difficult time communicating, both among themselves and with others not similarly handicapped. In fact, it is often more difficult to conduct a simple conversation between a non-handicapped person and one that is deaf or mute, because the non-handicapped person usually is not familiar with American Sign Language (ASL). Even when the persons communicating are familiar with ASL, sign language is not a very convenient method of communication when a large group is involved. Expensive television cameras and video screens must be employed to transmit messages to large audiences. That is, unless the receiver of the message is so close to the message transmitter that he or she can distinguish ASL gestures and the expressions on the message transmitter's face, communication is simply not possible. As mentioned previously, if the message receiver has not been trained to understand ASL, then communication is also not possible. Web site: http://www.delphion.com/details?pn=US06240392__ •
Communication system for deaf, deaf-blind, or non-vocal individuals using instrumented glove Inventor(s): George; William R. (Palo Alto, CA), Kramer; James P. (Stanford, CA), Lindener; Peter (E. Palo Alto, CA) Assignee(s): The Board of Trustee of the Leland Stanford Junior University (Stanford, CA) Patent Number: 5,047,952 Date filed: October 14, 1988 Abstract: A communication system for deaf, deaf-blind, or non-vocal individuals includes an instrumented glove for obtaining electrical signals indicative of a hand configuration of a first individual. Strain gage sensors in the glove flex with movement of the hand. Each sensor includes a tension strain gage and a compression strain gage which are serially connected and form two legs in a bridge circuit. Signals from the bridge circuit are amplified and digitized and applied to a computer which includes an adaptive pattern recognition algorithm which is responsive to hand-state vectors for recognizing letter beacons in hand-space. A second individual communicates with the first individual through the computer system using a portable keyboard. The output devices for communicating to the first and second individuals depend on the visual, vocal and hearing capabilities of the individuals and can be selected from a voice synthesizer, LCD monitor, or braille display. Excerpt(s): This invention relates generally to communication devices for deaf, deafblind, or non-vocal individuals, and more particularly the invention relates to a communication system which utilizes an instrumented glove. While many deaf persons communicate effectively using a form of sign language or the fingerspelling alphabet, problems arise when a hearing person, who does not know sign language, attempts to interact with a deaf individual who does not know the "oral" method, i.e., cannot speak
Patents 153
intelligibly and read lips. For deaf-blind persons, communication is even more difficult since they must be able to touch the hand of the person with whom they wish to interact. These communication difficulties adversely effect interpersonal relationships and vocational activities. Consequently, many deaf, deaf-blind and non-vocal people avoid situations requiring interaction with hearing persons. These disabled individuals often remain unemployed and dependent, and cannot fully participate in community life. The most common ways a nonvocal deaf or deaf-blind person communicates with a hearing person who does not know sign language are via interpreters and notewriting. Although interpreters are effective in translating sign language or fingerspelling into speech and vice versa, they are often expensive and difficult to acquire on a moment's notice. Use of an interpreter also leads to a loss of independence and privacy. Notewriting is used by many nonvocal individuals to communicate with someone who is seated nearby, but it is awkward while walking, standing at a distance, and when more than two persons participate in a conversation.

Device for mounting a telecommunications device for the deaf in a public phone booth Inventor(s): King; Bruce A. (3956 Downes Dr., Indianapolis, IN 46236) Assignee(s): none reported Patent Number: 4,903,290 Date filed: July 22, 1988 Abstract: A device for mounting a telecommunictions device for the deaf ("TDD") to a pay telephone booth which provides an enclosure for storing the TDD when not in use, and a mechanism for attaching the TDD to the booth so that it can be moved between a position where it is contained within the enclosure to a position where the handset of the telephone may be received in the handset cradle of the TDD to provide access to public telephone to the deaf and hearing impaired. Excerpt(s): This invention relates to a device for mounting appliances in a public telephone booth and more particularly to a device for mounting a telecommunications device for the deaf in a telephone booth. Deaf and hearing impaired people are unable to use standard telephones for communication unless they and the party with whom they are communicating both have a telecommunications device for the deaf ("TDD"). TDD's typically have a cradle for receiving a telephne handset, a keyboard for typing in outgoing messages, a means for converting typed messages to signals which can be transmitted over telephone lines and a means for converting signals received over telephone lines to a visual display. Thus, TDDs are often fairly large in size and are too cumbersome to make portability practicable. Therefore, TDDs are typically used only in the home or office environment. Because it is not practical for a deaf or hearing impaired person to carry TDDs around with them, the deaf and hearing impaired are essentially denied access to public telephone booths. The inventor is unaware of any prior art which discloses a TDD mounted in a public telephone booth. However the inventor is aware of two U.S. Patents which disclose public telephone booths with devices therein for holding telephone directories. These patents are Chambers (U.S. Pat. No. 2,982,593 issued May 2, 1961) and Hickman et al. (U.S. Pat. No. 4,323,290 issued Apr. 6, 1982). Web site: http://www.delphion.com/details?pn=US04903290__

Digital hearing aid Inventor(s): Ishige; Ryuuichi (Tokyo, JP), Mitome; Yukio (Tokyo, JP) Assignee(s): Nec Corporation (Tokyo, JP) Patent Number: 5,838,801 Date filed: December 9, 1997 Abstract: A digital hearing aid has input means for converting an input sound into a digital data for generating an input data, analyzing means for analyzing the input data converted by the input means by a digital conversion and calculating an acoustic pressure at each frequency band, control means for inputting a result of calculation by the analyzing means, acoustic sense characteristics storage means for preliminarily storing acoustic sense characteristics of a deafness and a person having healthy acoustic sense from a fitting means, gain calculation data storage means for preliminarily storing an acoustic pressure range the easiest to hear for the deafness from the fitting means, and acoustic sense compensating means for performing acoustic sense compensation process by amplifying the input data with a given gain. The control means calculates the gain of each frequency range on the basis of the acoustic sense characteristics and an acoustic pressure range stored in the acoustic sense characteristics storage means and the gain calculation data storage means. Excerpt(s): The present invention relates a digital hearing aid or hearing aid for sensorineural deafness using a digital signal processing. A hearing impairment, i.e. deafness, is generally classified into two kinds, i.e. conductive deafness and sensorineural deafness. The conductive deafness is a hearing impairment caused for variation of transmission characteristics due to failure of any one or all of external ear, middle ear. This type of hearing impairment can be simply overcome by amplifying input sound. Web site: http://www.delphion.com/details?pn=US05838801__

Educational apparatus and method for control of deaf individuals in a mixed teaching environment Inventor(s): Sapora; Robert (825 Holiday La., Westminster, MD 21157) Assignee(s): none reported Patent Number: 4,368,459 Date filed: December 16, 1980 Abstract: Radio signaling apparatus is for use, primarily, in classrooms at all educational levels, elementary school through graduate school, in which a teacher and a mixed body of hearing and deaf students participate in a lecture and discussion situation with the support of a trained interpreter in sign language. The radio system comprises a voice actuated pulsed omnidirectional radio transmitter, which is worn by the teacher, and a plurality of portable receiving devices, one for each deaf student. The microphone of the transmitter is selected to discriminate against ambient sounds and background voices. The omnidirectional receivers detect the pulsed radio transmissions and generate by transducer action a non-audible sensory stimulation to alert each individual deaf student, whereupon each such student should renew his or her observation of the interpreter. In a preferred embodiment the radio apparatus provides a flashing visual signal from each deaf student's receiver. The receiver and transducer are to be worn or
Patents 155
placed within the student's peripheral field of vision when the student is working on or is reading his class notes and texts during classroom sessions. The system is adaptable to more general uses outside the classroom. Excerpt(s): The requirements of the present invention for electronic components, circuits, and radio devices are totally satisfied by well-known and well-developed arts of manufacture in the electronic and radio industries. Furthermore, it is also evident in the existing arts that the loss, by a human, of a sensory capability, such as hearing, can be compensated, at least in part, by augmentation or expanded usage of one or more of the other human senses, i.e., sight, touch, taste and smell. In the case of complete loss of hearing, via the auditory organs, perception and information transfer to the handicapped individual is presently most frequently accomplished through visual or touch sensations. However, in the field of education, specifically of the deaf, reliance upon visual aids including sign language interpretations presently results in deficiencies in information transfer from teacher to student. These deficiencies are of such magnitude as to seriously depreciate the learning process of the deaf. The deaf must, on occasion, look at other legitimate classroom objects and are likely to miss important portions of the instructions. The following references in the existing arts are relevant to compensation for an impairment in hearing ability by augmentation and use of alternative sensory capabilities of the human body. These references do not, however, disclose or teach the present invention. Web site: http://www.delphion.com/details?pn=US04368459__ •

homozygous mutation in KVLQT1, the potassium channel gene responsible for chromosome 11-linked long QT syndrome, is shown to be a cause of JLN. Excerpt(s): Jervell and Lange-Nielsen syndrome (JLN) is an autosomal recessive form of long QT syndrome (LQT). In addition to QT interval prolongation, this disorder is associated with congenital deafness. JLN is rare, but affected individuals are susceptible to cardiac arrhythmias with a high incidence of sudden death and short life expectancy. The present invention is directed to a mutation in the KVLQT1 gene which results in Jervell and Lange-Nielsen syndrome and to probes and methods for diagnosing the presence of JLN. JLN is diagnosed in accordance with the present invention by analyzing the DNA sequence of the KVLQT1 gene of an individual to be tested and comparing the respective DNA sequence to the known DNA sequence of a normal KVLQT1 gene. The publications and other materials used herein to illuminate the background of the invention or provide additional details respecting the practice, are incorporated by reference, and for convenience are respectively grouped in the appended l ist of References. Cardiac arrhythmias are a common cause of morbidity and mortality, accounting for approximately 11% of all natural deaths (Kannel, 1987; Willich et al., 1987). In general, presymptomatic diagnosis and treatment of individuals with life-threatening ventricular tachyarrhythmias is poor, and in some cases medical management actually increases the risk of arrhythmia and death (Cardiac Arrhythmia Suppression Trial II Investigators, 1992). These factors make early detection of individuals at risk for cardiac arrhythmias and arrhythmia prevention high priorities. Web site: http://www.delphion.com/details?pn=US06150104__ •
Method and apparatus for communicating information representative of sound waves to the deaf Inventor(s): McConnell; Jeffrey D. (3504 W. Sixth, Spokane, WA 99204) Assignee(s): none reported Patent Number: 4,813,419 Date filed: March 22, 1988 Abstract: A method and apparatus of communicating audio signals to the deaf is described. In accordance with the method described, electrical impulses characteristic of sound waves are applied either directly to the tactile sensory nerves by means of an implant or are applied simultaneously with vibrations representative of the sound waves to the nerve endings located at the skin surface. In accordance with the apparatus, a nerve stimulator applies a voltage representative of the sound waves across a pair of implanted electrodes in contact with the tactile sensory nerve such as the radial nerve branch located in the wrist or applies vibrations representative of the sound waves by means of a transducer to the skin, e.g. the finger tips of the deaf person, and electrical impulses representative of the sound waves across a pair of spaced electrodes carried by the transducer so that the same nerve endings are stimulated with both the vibrations and the electrical impulses. Excerpt(s): The present invention relates to a method and apparatus for communicating information representative of air pressure sound waves to deaf persons, and more particularly to a method and apparatus for translating sound waves into electrical signals and stimulating the tactile sensory nerves of the deaf person in accordance with such electrical signals. The prior art's efforts at providing some measure of hearing for the totally and partially deaf has been directed primarily at stimulating the inner ear or
158 Deafness
cochlea with signals derived from sound waves. The stimulated cochlea would in theory transmit signals to the brain through the auditory nerve, which could be translated into information representing the original sound waves. One example of such prior art efforts is described in an article entitled "Success for the `Bionic Ear,`" appearing in the Mar. 12, 1984 issue of Time Magazine. According to this article, eight wires are implanted in the deaf person's inner ear and connected to an electrical plug extending through the skull. A microphone carried on the ear translates the sound waves into electrical signals which are then processed by a computer and applied to the implanted wires. Such prior art devices require delicate surgery, are expensive, and have not yet met with any great success. Web site: http://www.delphion.com/details?pn=US04813419__ •
Method and apparatus for sound responsive tactile stimulation of deaf individuals Inventor(s): Franklin; David (9 Preston Rd., Somerville, MA 02143), Franklin; Joseph (9 Preston Rd., Somerville, MA 02143), Hughes; Paul (17 Howell Rd., Sudbury, MA 01776) Assignee(s): none reported Patent Number: 5,035,242 Date filed: April 16, 1990 Abstract: A tactile aid for deaf individuals includes a conveniently wearable array of vibration transducers mounted on a flexible carrier strip so as to be positionally biased toward the individuals's skin. Each transducer includes an enclosed magnetically vibratable cantilevered beam, an angled mounting slot to effect the positional bias mounting on the strip, and contact pads rather than conventional pin connectors to both reduce mass and facilitate electrical connection to contact pads on carrier strips in the form of printed circuit boards. Received acoustic signals are processed in at least first and second formant circuits each sub-divided into plural sub-bands corresponding to the number of transducers. In each formant circuit the corresponding formant frequency and amplitude are measured, averaged over a predetermined number of cycles, and a voltage corresponding to the measured amplitude is provided on a corresponding subhand channel to pulse width modulate a pulse train employed to excite the transducers. Spectral resolution can be increased by averaging the amplitude/frequency measurements over fewer cycles. Glottal pulses in the speech signal are monitored to provide a glottal rate signal at a stepped down frequency related to the actual glottal rate. The channel amplitude is modulated by the glottal signal to cause alternation of transducer excitation at the related glottal rate. Additional formants may be detected to derive additional information in the excitation signal. Excerpt(s): The present invention relates to methods and apparatus for converting acoustic signals to signals capable of being perceived by tactile sensing. More particularly, the present invention relates to wearable tactile devices for deaf individuals who have essentially no useful input from their own damaged auditory system. The primary utility of the present invention is to provide a means whereby such deaf individuals have access to the world of sound, both for communication purposes and, in the special case of prelingually deafened children (i.e. those either being born deaf or losing their hearing before attaining significant language capability), for learning speech and language at as early an age as possible and in as nearly natural a way as possible. As such, it is clear that a great emphasis for devices in this class must be on cosmetics and ease of use, as well as processing methods, since continuous wearing is a necessary requirement if the above goals are to be met. Before discussing the prior art in detail, it is
Patents 159
important to note that, in addition to tactile sensing, there is a somewhat related class of devices called cochlear implants. As the name implies, these are devices having a stimulator implanted directly into the inner ear of a deaf individual for the purpose of obtaining some degree of hearing restoration. Generally speaking, an important distinction between tactile devices and cochlear implant devices is that cochlear implants attempt to restore some degree of the lost sense of hearing while tactile devices attempt to substitute the tactile sensory mode for the lost hearing sense. Hence, the transducers for both types of devices differ markedly, and the processing must also differ in order to accommodate the different transducer functions and different sensory modes. Tactile aid technology dates back to 1927; however, only developments since 1986 are relevant since it is within that time frame that devices with the necessary compactness and convenience to be worn continuously have made their appearance. All such devices presently in use have only one or at most two channels in spite of the fact that it has long been recognized that it is desirable to use multiple channels, each functioning in some way to analyze speech waveforms and other acoustical events according to one of a number of possible paradigms, and to present detailed information about the sound events via a multiplicity of skin exciters. It is generally understood that only in this way can enough detailed information be presented to a user sufficiently clearly and uniquely to enable him to eventually learn to recognize and appreciate the sound events in a manner analogous to that by which the intact hearing system receives, analyzes and appreciates the same sound events.

Method and apparatus for visual telecommunications, in particular for use by the deaf Inventor(s): Abramatic; Jean-Francois (Noisy le Roi, FR), Letellier; Philippe (Versailles, FR), Nadler; Morton (La Celle Saint Cloud, FR) Assignee(s): INRIA Institute National de Recherche en Informatique et en Automatique (Le Chesnay, FR) Patent Number: 4,546,383 Date filed: June 17, 1983 Abstract: In a system for visual telecommunications, e.g. for use by deaf people, an electronic camera (20) makes an image of a moving subject for transmission. The TV type image is passed through a contour extractor (25) to be converted to an animated cartoon line-drawing type image. The contour image is then compressed by means including a sampler (28) for image reduction, a difference detector (30) for selecting only points which change from one image to the next, a filter (34) for rejecting isolated points in the contour image, and an encoder (36) for converting sequences of on/off bits into data words for transmission, via a modem (14) over a telephone line (15). At the other end of the line a similar transmitter/receiver system decodes the received words and reconstitutes the successive images for display on a screen (46). The resulting animated cartoon type of display is adequate for communication by sign language or by lip reading, and is capable of being sufficiently compressed to be transmitted over a normal telephone line. Excerpt(s): The present invention relates to telecommunications, and in particular to telecommunications by telephone or telematics lines. The invention aims more particularly at transmitting images over such links, where it is understood that telephone links are not limited to cables or electric lines but also include communication
160 Deafness
links such as microwaves, optical fibers, etc. Telephone lines have traditionally been developed and installed in networks for transmitting voice communications. More recently, they have found a use in transmitting digital type data, by means of modulator-demodulators generally known as modems. Such telephone links have transmission characteristics which are well adapted to transmitting analog signals at frequencies of not more than about 4 kHz. When they are used for transmitting digital signals, they tend to be useable at data rates of up to about 4800 bauds. Such performance limits the volume of information which may be transmitted in given time. Thus, while telephone lines are well adapted to transmitting human speech or to transmitting computer messages in the form of relatively low data rate binary signals, they are not suitable for real time transmission of images which are liable to change quickly in time. Image transmission requires a relatively large amount of information to be transferred in comparison to the volume of information needed for a voice message. The image must be divided into point-like zones or "pixels" which are smaller with increasing definition to be transmitted. A signal representative of the brightness of each pixel must be produced. The set of such signals must then be transmitted, generally in series in the form of a sequence. Each sequence corresponds to an image, and the level of the signal at a given instant in the sequence corresponds to the brightness of a corresponding point in the transmitted image.

Method and device for presenting information to deaf persons Inventor(s): Traunmuller; Hartmut (123 Bjornstigen, Solna, SW) Assignee(s): none reported Patent Number: 4,025,732 Date filed: July 22, 1976 Abstract: In a device for presenting information to deaf persons an electroacoustic signal from a microphone is supplied to a high-pass and to a low-pass channel via an amplifier. The relation between the envelope potentials of the high-passed and the lowpassed signals is sensed by means of logarithmic circuits and a differential amplifier, the output potential of which determines the frequency of a voltage controlled oscillator. By means of a dynamic-adapting signal, derived from the electroacoustic signal, an amplitude modulation of the oscillator output is provided. The accordingly obtained amplitude modulated signal is used to drive tactile or auditive transducers. Excerpt(s): The invention relates to a method for presenting information obtained from an electroacoustic signal, especially a speech signal, via tactile or auditive transducers, and to a device for carrying out the method, intended to be used by deaf persons, and presenting such information, which is suitable as a complement to lipreading. Deaf persons without or with only insignificant residual hearing do not get any essential help by using hearing-aids. They are for speech perception constrained to use lip-reading. However, only lipreading does not make a full understanding of speech possible. Different ways of making further information in the speech available at a simultaneous lipreading have been known. A simple method consists in driving a tactile transducer (vibrator) directly with an amplified electroacoustic signal. The vibrator can be sensed by the deaf person for instance with the fingers or via the teeth. The additional information, perceptible in this way, does, however, still not make a full understanding of speech possible.

Method for detection of susceptibility mutations for ototoxic deafness Inventor(s): Fischel-Ghodsian; Nathan (Los Angeles, CA), Prezant; Toni R. (Reseda, CA) Assignee(s): Cedars-Sinai Medical Center (Los Angeles, CA) Patent Number: 5,506,101 Date filed: June 30, 1993 Abstract: Method for detection of mitochondrial nucleotide associated with predisposition for ototoxic deafness, especially deafness associated with the administration of aminoglycosides, is described. Excerpt(s): This invention relates to the area of genetic diagnosis. More specifically, the invention relates to detection of an alteration of wild-type mitochondrial ribosomal RNA(rRNA) which is associated with ototoxic deafness in humans. Sensorineural deafness, either in conjunction with neuromuscular diseases or with diabetes, has been associated with heteroplasmic mitochondrial DNA (mtDNA) mutations (Shoffner, et al., Adv. Human Genet., 19:267-330, 1990; Ballinger, et al., Nature Genet., 1:11-15, 1992; van den Ouweland, et al., Nature Genet., 1:368-371, 1992; Reardon, et al., Lancet, 34:13761379, 1992). The likelihood of mtDNA mutations has also been suggested in two forms of non-syndromic deafness. A maternal inheritance pattern has been reported in several pedigrees in the Far East with familial aminoglycoside-induced deafness (Higashi, Clin. Genet., 35:433-436, 1989; Hu, et al., J. Med. Genet., 28:79-83, 1991), and a single large Arab-Israeli pedigree with maternally-inherited congenital deafness has been described (Jaber, et al., J. Med. Genet., 29:86-90, 1992). Mitochondrial DNA is transmitted exclusively through mothers, since the sperm apparently contributes no mitochondria to the zygote. This leads to the expectation that a defect in a mitochondrial gene should lead to disease equally in both sexes, but can only be transmitted through the maternal line. There are hundreds of mitochondria in each cell and they serve a variety of metabolic functions, the most important being the synthesis of ATP by oxidative phosphorylation. Each mitochondrion contains several mitochondrial DNA (mtDNA) chromosomes, which in humans are 16,569 basepairs (bp) double-stranded circles. Replication, transcription, and translation of the mtDNA occurs within the mitochondrion. The mitochondrial DNA encodes 13 messenger RNAs, and the large and small ribosomal RNAs and 22 transfer RNAs which are necessary for their translation. The messenger RNAs are translated on mitochondrion-specific ribosomes, using a mitochondrion-specific genetic code, into 13 proteins. These proteins interact with approximately sixty nuclear encoded proteins to form the five enzyme complexes required for oxidative phosphorylation.

Methods for communicating with a telecommunications device for the deaf Inventor(s): Lynn; Joe J. (Gaithersburg, MD), Morduch; Georg E. (Alexandria, VA) Assignee(s): Microlog Corporation (Germantown, MD) Patent Number: 5,670,957 Date filed: June 7, 1995
162 Deafness
Abstract: An automatic telephone answering system employs a switch activated by any of several techniques to select a language for communication with a caller. A single matrix determines the content of a message to be generated in response to input from the caller. A single matrix can be used because it is arranged in accordance with the content of the various messages and not on the specific language of the messages. All of the messages for each respective language are stored in a separate directory such that a given identifier obtained from the matrix will recall that message in the language determined by identification of the particular directory. A telecommunications device for the deaf (TDD) is treated in the same manner as a language and selection of messages employs the same matrix used for traditional languages. Received TDD signals are converted to ASCII for storage, and messages to be identified by the matrix are stored in ASCII and converted to TDD before transmission. Excerpt(s): This invention relates to the art of automatic telephone systems capable of communicating in several languages. Automated telephone answering systems are known. These systems are capable of delivering prerecorded messages and of receiving inputs from the caller either in the form of signals from the telephone, such as the Touch Tone or rotary dial signals, or voice messages from the caller. These systems communicate with humans either directly by producing the sounds of human speech or indirectly through signals which are interpreted by an electrical or electromechanical device. An automated telephone system generally consists of an input module, a control module, and an output module, even though the line of distinction is sometimes not clear. The control module may be the CPU of a computer while the input and output modules are combined in a single input-output processor (IOP) which may also be located in the computer.

Middle ear implant Inventor(s): Dalchow; Carsten (Dusseldorf, DE), Elies; Wolfgang (Bielefeld, DE) Assignee(s): Spiggle & Theis (Dieburg, DE) Patent Number: 6,432,139 Date filed: August 17, 2000 Abstract: Deafness is often caused by damage to the ossicular chain, which at present is partly or fully replaces by surgical implantation of a corresponding titanium prosthesis. Known versions of this type of middle ear implant consist of a flat coupling body (8) designed to rest against the ear drum, an oblong shank (3) connected to the body for bridging the tympanic cavity and a base (4,11) which is joined to the shank (3) and rests against the base of the implant in the tympanic cavity. Because the depth oft he tympanic cavity varies from patient to patient and measurements become known only during surgery, the length of the implant has to be adjusted very quickly. To be able to do this more simply than is possible with the known implants having a fixed length, the middle ear implant provided by the invention is characterized in that the oblong shank (3) has separation zones (6) to allow for individual adjustment of the shank length to the patient-specific depth of the tympanic cavity during the surgical intervention, and in that the base (4, 11) and/or the flat coupling body (1, 8) are embodied as a slide-on connector part which houses the corresponding end of the shank (3). Excerpt(s): The present invention relates to a middle ear implant with a flat coupling body for application against the eardrum, an elongated shaft connected therewith for
Patents 163
spanning the space in the tympanic cavity, and a shaft-connected base for application against the supporting point for the implant in the tympanic cavity. Impaired hearing ranging up to deafness can have different pathological causes. One oft he causes typically lies in a disease-related change in or degeneration oft he small auditory bones of the ossicular chain in the middle ear, i.e., the three ossicles positioned in the tympanic cavity (Cavum tympani): the hammer, the anvil, and the stirrup. These ossicles carry sound transmission from the eardrum via the vestibule window (vestibular window) to the inner ear, the air in the middle ear making possible almost friction-free vibration of the ossicles combined together in articulated fashion. These articulated ossicles represent a lever mechanism which amplifies the recorded sound waves in the case of humans by about two to three times. If the lever mechanism is disturbed, e.g., through a degenerative change in the bone substance, a person will become hard of-hearing. Web site: http://www.delphion.com/details?pn=US06432139__ •
Mutated polynucleotide corresponding to a mutation responsible for prelingual nonsyndromic deafness in the connexin 26 gene and method of detecting this hereditary defect Inventor(s): Denoyelle-Gryson; Francoise (Arcueil, FR), Guesdon; Jean-Luc (Sevres, FR), Marlin-Duvernois; Sandrine (Colombes, FR), Petit; Christine (Le Plessis-Robinson, FR), Weil; Dominique (Paris, FR) Assignee(s): Institut Pasteur (Paris, FR) Patent Number: 5,998,147 Date filed: August 14, 1998 Abstract: A purified polynucleotide having a chain of nucleotides corresponding to a mutated sequence, which in a wild type form encodes a polypeptide implicated in hereditary sensory defect, wherein said mutated purified polynucleotide presents a mutation responsible for prelingual non-syndromic deafness selected from the group consisting of a specific deletion of at least one nucleotide. Excerpt(s): The present invention concerns a mutation responsible for autosomal prelingual non-syndromic deafness and a method for the detection of this hereditary sensory defect for homozygous and heterozygous individuals. The invention concerns more particularly a specific deletion of at least one nucleotide in the connexin 26 (Cx 26) gene and especially in a guanosine rich region, notably between the nucleotides 27 and 32. The invention is also directed to the use of polynucleotide, or fragments thereof, for example as tools useful for the in vitro detection of a mutation of a gene belonging to the Cx26 gene family. Profound or severe prelingual deafness affects one child in a thousand in developed countries (Morton N E. Genetic epidemiology of hearing impairment. In Genetics of hearing impairment. (The New York Acad Sci, New York 1991; 630:16-31). It is a major handicap as it impedes language acquisition. According to studies performed in a U.S. population of children with non-syndromic (isolated) prelingual deafness and in whom an obvious environmental cause has been excluded, it is estimated that up to two-thirds of the cases have a genetic basis (Marazita M L, Ploughman L M, Rawlings B, Remington E, Arnos K S, Nance W E. Genetic epidemiological studies of early-onset deafness in the U.S. school-age population. Am J Med Genet 1993; 46:486-91). These forms are mainly sensorineural and are almost exclusively monogenic. The major mode of inheritance is autosomal recessive (DFNB), involving 72% to 85% of cases, this fraction increasing to 90% when only profound deafness is taken into account.

Excerpt(s): The present invention relates to a pharmaceutical composition for the treatment of idiopathic sudden sensorineural hearing loss in human patients. Among inner ear deafnesses which have an abrupt onset, deafness with unknown etiology is called idiopathic sudden sensorineural hearing loss (abbreviated ISSHL hereunder). Reference No. 1 (References referred to in the present specification are listed hereinafter), for example, describes: "The Research and Study Group of the Ministry of Health & Welfare: 1973--Idiopathic Sudden Sensorineural Hearing Loss in Special Diseases", as one criteria for diagnosis, calls for "where the time of the initial onset of the symptoms can be clearly determined" and removes from the criteria, "those where etiology can be clearly known". In other words, ISSHL is a syndrome having acute deafness to sound as the main symptom, of which causes are unknown; the onset mechanism and pathema are still under hypotheses. The major proposed hypothetical etiologies are circulation disorder in auris interna, viral infection and labyrinthine window breaks. Those etiologies are merely hypothetical, owing to the impossibility of experimental models of the ISSHL, scarcity of autopsies and those available being obsolete". (see Reference No. 1). Currently, ISSHL patients are treated with a steroids, cardiovascular agents and vitamins in combination therewith for the purpose of improving blood circulation. Because etiology and pathema of the disease are still unknown, such treatment has not resulted in decisive improvements (see Reference Nos. 1, 2 and 3). Particularly, the treatment for the severe type of ISSHL has not reached any satisfactory results, even where the treatment has been undertaken at an early stage of the disease. Thus, the recovery of practical audio abilities could not be currently obtained. Web site: http://www.delphion.com/details?pn=US05698232__

Receiving caller identification information with a telecommunications device for the deaf Inventor(s): Quagliana; Douglas D. (Edison, NJ) Assignee(s): Intel Corporation (Santa Clara, CA) Patent Number: 6,560,317 Date filed: January 3, 2002 Abstract: A central office (CO) for a telephone connected with a telecommunication device for the deaf (TDD) called by a calling device determines that the called TDD is
Patents 165
connected with the called CO. The called CO postpones indication that the called TDD has connected with the called CO, until the called CO determines whether the called TDD is willing to connect with the calling device. This causes the calling device to continue to receive an indication that a connection has yet to be established between the calling device and the called TDD. As a result of being connected with the telephone connected with the TDD, the called CO transmits caller identification (CID) information regarding the calling device in a format that can be received by a TDD. Excerpt(s): The present invention relates to receiving caller identification (CID) information with a telecommunications device for the deaf (TDD). Wired telephones are connected to a telephone company's central office (CO) through a two-wire circuit called a local loop. A CO contains switching equipment that connects the telephone lines of a calling telephone terminating at one CO to the telephone lines of a called telephone terminating at another CO. When the switches between a telephone and a CO are open (e.g., because a telephone handset is holding down a switchhook), there is no connection between the telephone and the CO. However, once the switches between a telephone and a CO are closed (e.g., because the telephone handset is removed, causing the switchhook to lift up), the local loop is complete, thus establishing a connection between the telephone and the CO. When a calling telephone is connected with the calling telephone's CO (the "calling CO"), it generates a signal that tells the calling CO that a person wants to make a call. The calling CO returns a dial tone to the calling telephone indicating that the calling CO is ready to accept a telephone number. The person dials a telephone number that is sent to the calling CO. The calling CO transmits the telephone number over a telephone network and connects with a called telephone's CO (the "called CO"). Web site: http://www.delphion.com/details?pn=US06560317__ •
Ringing detector for use by the deaf Inventor(s): Sparber; Richard G. (Wheaton, IL) Assignee(s): Bell Telephone Laboratories, Incorporated (Murray Hill, NJ) Patent Number: 4,379,210 Date filed: May 28, 1981 Abstract: A ringing detector circuit for use by the deaf which may be connected between the tip and ring conductors (11, 12) of a subscriber set to cause an incandescent lamp (40) to flash to half brightness when ringing voltage is applied to the line. Closing a manual switch (22) allows the lamp (40) to burn at half brightness when the phone is not ringing and to flash to full brightness when the phone is ringing. Excerpt(s): This invention relates to telephone ringing detectors for use by the deaf and, more particularly, to such detectors including a visual indicator. One important result of the recent, increased social awareness of the needs and rights of handicapped persons has been the development of telecommunications devices for the deaf (TDD). Such devices, typically comprising a battery-powered, microprocessor-controlled teletypewriter with moving visual display, are acoustically coupled to conventional telephones to permit hearing-impaired persons to communicate readily and conveniently with others. Special provisions must be made to alert hearing-impaired persons of incoming calls. One known ring indicator can be connected to any room lamp to cause the lamp to flash on repeatedly when ringing voltage is present on the telephone line. Further, if the lamp is being used to illuminate the room, the indicator
166 Deafness
will cause the lamp to flash off repeatedly to alert the hearing-impaired person. However, from a human-factors viewpoint, such an indicator is highly undesirable when the lamp used for alerting is also used to illuminate the room because the people in the room will be subjected to darkness during the active part of each ringing cycle. Accordingly, it is an object of the present invention to provide a reliable, inexpensive ringing detector which can be employed in conjunction with a lamp used for room illumination without annoying light interruptions during ringing.

Shared bus arbitration apparatus having a deaf node Inventor(s): Abidi; Mohammad V. (Shrewsbury, MA), Cao; Xi-Ren (Acton, MA), ColonOsorio; Fernando (Stow, MA), Lary; Richard F. (Colorado Springs, CO), Quaynor; Nii (Shrewsbury, MA) Assignee(s): Digital Equipment Corporation (Maynard, MA) Patent Number: 5,239,630 Date filed: July 2, 1990 Abstract: An improved arbitration technique for a computer network system in which multiple nodes communicate using a shared bus, and at least one node has no knowledge of the current status of the arbitration taking place between all nodes in the system. Such a node is called a "deaf node". Each node in the system is assigned an initial arbitration count number, for example, N+1, where N is the node number assigned to the node. The arbitration count number is the number of quiet slots a node must count before trying to transmit on the system bus. The length of a quiet slot is determined by a particular system's electrical characteristics. One quiet slot is reserved as the "deaf node quiet slot", during which a deaf node may transmit. In response to a transmission occurring in the deaf node quiet slot, each node in the system reinitializes its arbitration count number to its initial arbitration count number. Additionally, a node that is not a deaf node, but has detected a system error, may deliberately transmit during the deaf node quiet slot to reinitialize the arbitration count numbers or the internal clocks of all nodes in the system. Excerpt(s): This invention relates to computer systems having nodes communicating through a bus, and more particularly to an arbitration apparatus for determining which node transmits next on the bus. A computer system may have a number of nodes communicating with each other through a bus. The nodes may be individual computers, controllers for mass storage devices, or other computer apparatus. A problem arising in such a system architecture is the problem of determining which node transmits next on the bus. For example, a first node may be presently transmitting a message on the bus. Upon the conclusion of that transmission, there may be several nodes seeking to begin transmission. If more than one node begins transmission at the same time, say at the completion of the transmission of the first nodes, then a data collision will occur. The problem of determining which node transmits next on a shared, multiple access, bus is termed the "arbitration problem". The arbitration problem may be solved by having a node test the bus in order to determine if carrier is present on the bus, and then to either begin transmitting in the absence of carrier, or if carrier is detected to initiate a backoff protocol as in the well known Ethernet or CSMA/CD (Carrier Sense Multiple Access/Collison Detect protocol). An improved solution of the arbitration problem is for a node to count a number of "quiet slots" after detecting the absence of carrier on the bus, in order to minimize the probability that a data collision will occur when the node
Patents 167
begins transmitting, where a quiet slot is a predetermined time interval, and a fixed number of quiet slots is assigned to each node. An even further improvement in the arbitration protocol makes use of a re-assignment of the fixed number of quiet slots assigned to each node, where the re-assignment is done according to rules designed to reduce bandwidth of the bus used in counting quiet slots.

Speech pattern correction device for deaf and voice-impaired Inventor(s): Davis; Stephen A. (Coral Springs, FL) Assignee(s): Davis, Van Nortwick & Company (Gainesville, FL) Patent Number: 5,146,502 Date filed: February 26, 1990 Abstract: A portable voice or speech aid enabling a deaf or voice impaired user to make sounds into a microphone to output intelligible speech through a built-in speaker or to a text display screen. Excerpt(s): This invention relates to computer aided devices enabling deaf or voiceimpaired people to communicate. Computer aid devices for deaf or voice-impaired persons fall into two categories. The first type avoids the need for the production of speech. For example, a computer can interpret hand positions signed by deaf people, or can allow deaf people to type messages which can be transmitted over telephone lines. The second type of device teaches the deaf to speak understandably. But in using the second category, the voice impaired person may not be able to learn to speak understandably, and a deaf person may find learning difficult and time consuming. For both deaf and voice impaired, the user effort may be extensive and results may be embarrassing. However, it is important to recognize that deaf or voice-impaired people can utter sounds in a reasonably consistent fashion. Web site: http://www.delphion.com/details?pn=US05146502__

Stapedial-saccular strut and method Inventor(s): Lenhardt; Martin L. (Hayes, VA) Assignee(s): Sound Techniques Systems, LLC (Arlington, VA) Patent Number: 6,368,267 Date filed: October 14, 1999 Abstract: A system and method for an auditory inner ear prosthesis. A strut connects the medial surface of the stape footplate with the wall of the saccule. The strut spans the 1.5 mm vestibule between the saccule and the stapes. The strut is a synthetic elastic connector constructed of biocompatible material such as sylastic. The strut converts eardrum or ossicle vibration into saccular stimulation. The saccule is a large otic receptor organ capable of coding sound, and plays a role in reptilian hearing. For human ears, the saccule is so isolated from the eardrum and related elements that sound stimulation is ineffective. The strut allows for better stimulation by direct coupling. In cases of deafness, the saccule can serve as an alternative ear.
168 Deafness
Excerpt(s): The present invention relates to a system and method for an auditory ear prosthesis. In particular, the present invention relates to the construction of a strut for connecting the medial surface of the stape footplate with the wall of the saccule. One type of conventional hearing aid provides for an air-conduction amplifying system such that a microphone picks up air conduction sounds, amplifies them and presents them in the ear canals as an air conduction signal to the eardrum. Such hearing aids offer a small frequency range as well as a small dynamic range of intensity. Another type of conventional hearing aid is called a bone conduction hearing aid, which has been developed for users where the conventional air-conduction hearing aid is not satisfactory in improving hearing for those users. A bone conduction hearing aid is attached to the head of the user, and the output from a microphone pick-up is amplified and fed into a device which causes bone vibration. These devices operate over a small dynamic range and are designed principally for persons whose middle ears could not be surgically repaired or for very young children who have abnormalities of the middle ear that cannot be surgically repaired until they are older. As such, bone conduction hearing aids are rarely used. Web site: http://www.delphion.com/details?pn=US06368267__ •

Telecommunication device for the deaf with automatic self-identification Inventor(s): Colwell; Kevin (Middleton, WI), Engelke; Robert M. (Madison, WI), Schultz; Ronald W. (Madison, WI) Assignee(s): Ultratec, Inc. (Madison, WI) Patent Number: 5,325,417 Date filed: May 20, 1992 Abstract: A telecommunication device for the deaf includes a self-identification sequence which automatically commences upon the initiation of communication with
Patents 169
the device. The self-identification sequence consists of a series of characters which may be separated by pauses and the device listens during the pauses to see if TDD communication has been established. The purpose of the character string is so that a receiving station can identify, with a low rate of error, a calling TDD and therefore switch the incoming call to a TDD equipped operator. This capability is particularly useful for emergency service operators (911 services) which must be able to handle incoming TDD calls with a maximum of efficiency and a minimum of error. Excerpt(s): The present invention relates to a telecommunication device for the deaf which is capable of automatically identifying itself to the party on the other end of the line. Persons who are deaf or hearing-impaired who cannot hear well enough to use the telephone commonly make use of communication terminals specifically constructed and designed to enable such persons to converse over the telephone lines. Such devices are referred to as telecommunication devices for the deaf or TDD and include both a keyboard and a display connected to the telephone through a modem (modulator/demodulator). The modem is typically built into the TDD and either directly wired to a telephone line or coupled through an acoustic coupler to a normal telephone handset. The TDD is capable of transmitting information over a telephone line by means of coded tones to another similar TDD connected at the opposite end of the telephone line through another modem. There are several protocols by which electronic devices are capable of communicating through analog lines, such as telephone lines. The most common used in the industry is referred to as ASCII (American Standard Code for Information Interchange), and is commonly used for information interchange between computers. However, historically, TDD have operated on a different protocol, referred to as Baudot. There is both a Baudot code and a protocol of communication referred to as Baudot/Weitbrecht.

Telephone communications system for the deaf Inventor(s): Meyer; Jerome Charles (1512 Ben Roe Ave., Los Altos, CA 94022) Assignee(s): none reported Patent Number: 4,012,599 Date filed: July 29, 1975 Abstract: A self-powered, portable, hand-held communicator and system provides a deaf user with a visual display of conversational information transmitted to him with a standard pushbutton telephone. A highly efficient and easily remembered encoding scheme is featured wherein the alphabetic character encoding utilizes the standard markings on the telephone pushbuttons and the relative positional location of the pushbuttons. Rapid tactile transmission of messages by a user is enhanced and user fatigue minimized by requiring only a single pushbutton stroke per hand to transmit any alphabetic character. User fatigue is additionally minimized by distributing pushbutton actuation requirements for normal conversation among a plurality of the fingers of each hand and by assigning control functions to pushbuttons having positions spatially and visually related to the encoding function they perform and to the user's finger positions during message transmission. Excerpt(s): This invention relates to an apparatus for enabling deaf persons to converse over ordinary pushbutton telephone instruments and more particularly to a communicator and system employing an encoding technique and control key selection
170 Deafness
designed to minimize user fatigue and to enhance rate of word transmission during a normal conversation between deaf users. Various systems have been disclosed for communicating data by using the pushbutton telephone set as a communications instrument. Flanagan et al in U.S. Pat. No. 3,675,513 describes a pushbutton telephoneteletypewriter communications system wherein encoded teletypewriter functions can be sent from either a special typewriter or a standard pushbutton telephone over telephone lines to a receiving typewriter for producing a permanent record of information received. Flanagan utilizes an encoding scheme requiring as many as four pushbutton strokes for selection of alphabetic characters. Multiple actuation is required of selected control keys for character selection. Steury in U.S Pat. No. 3,870,821 describes an improvement in pushbutton telephone communications systems of the general type described by Flanagan wherein a code chart display for indicating the particular set of characters, symbols or function signals is required. Selection and transmission of a desired alpha character can require three pushbutton actuations if an alpha portion of an alphanumeric message is transmitted by a device constructed as taught by Steury. It is an object of this invention to provide an apparatus to deaf users for communicating over standard pushbutton telephones wherein a visual indication of a received or transmitted alphabetic character is provided and transmission of an alphabetic character requires a maximum of only two pushbutton strokes.

Telephone for the deaf and method of using same Inventor(s): Liebermann; Raanan (79 Bayard Ave., North Haven, CT 06473) Assignee(s): none reported Patent Number: 5,982,853 Date filed: May 23, 1996 Abstract: An electronic communications system for the deaf includes a video apparatus for observing and digitizing the facial, body and hand and finger signing motions of a deaf person, an electronic translator for translating the digitized signing motions into words and phrases, and an electronic output for the words and phrases. The video apparatus desirably includes both a video camera and a video display which will display signing motions provided by translating spoken words of a hearing person into digitized images. The system may function as a translator by outputting the translated words and phrases as synthetic speech at the deaf person's location for another person at that location, and that person's speech may be picked up, translated, and displayed as signing motions on a display in the video apparatus. Excerpt(s): The present invention relates to electronic apparatus for communication by the deaf, and, more particularly, to such apparatus which enables the deaf person to communicate through use of sign language. Deaf people are employed in almost every occupational field. They drive cars, get married, buy homes, and have children, much like everyone else. Because of many inherent communication difficulties, most deaf people are more comfortable when associating with other deaf people. They tend to marry deaf people whom they have met at schools for the deaf or through deaf clubs. Most deaf couples have hearing children who learn sign language early in life to communicate with their parents. Many deaf people tend to have special electronics and telecommunications equipment in their homes. Captioning decoders may be on their televisions, and electrical hook-ups may flash lights to indicate when the baby is crying, the doorbell is ringing, or the alarm clock is going off. However, deaf persons have
Patents 171
substantial difficulties in communicating with persons at remote locations. One technique which is employed utilizes a teletype machine for use by the deaf person to transmit his message and also to receive messages, and the person with whom the deaf person is communicating also has such a teletype machine so that there is an effective connection directly between them. In another method, the deaf person utilizes a teletype machine, but the person who is communicating with the deaf person is in contact with a communications center where a person reads the transmission to the hearing person over the telephone and receives the telephone message from the hearing person and transmits that information on the teletype machine to the deaf person. Obviously, this teletype based system is limited and requires the deaf person to be able to manipulate a teletype machine and to understand effectively the written information which he or she receives on the teletype machine. Processing rapidly received written information is not always effective with those who have been profoundly deaf for extended periods of time. Moreover, a system based upon such teletype transmissions is generally relatively slow. Web site: http://www.delphion.com/details?pn=US05982853__

Alterations in the long QT syndrome genes KVLQT1 and SCN5A and methods for detecting same Inventor(s): Keating, Mark T.; (Brookline, MA), Splawski, Igor; (Allston, MA) Correspondence: Rothwell, Figg, Ernst & Manbeck, P.C.; 555 13th Street, N.W.; Suite 701, East Tower; Washington; DC; 20004; US Patent Application Number: 20020061524 Date filed: April 24, 2001 Abstract: Long QT Syndrome (LQTS) is a cardiovascular disorder characterized by prolongation of the QT interval on electrocardiogram and presence of syncope, seizures and sudden death. Five genes have been implicated in Romano-Ward syndrome, the autosomal dominant form of LQTS. These genes are KVLQT1, HERG, SCN5A, KCNE1 and KCNE2. Mutations in KVLQt1 and KCNE1 also cause the Jervell and Lange-Nielsen syndrome, a form of LQTS associated with deafness, a phenotypic abnormality inherited in an autosomal recessive fashion. Mutational analyses were used to screen 262 unrelated individuals with LQTS for mutations in the five defined genes. A total of 134 mutations were observed of which eighty were novel. Excerpt(s): The present invention is related to provisional application Ser. No. 60/190,057 filed Mar. 17, 2000, and is also related to provisional application Ser. No. 60/147,488 filed Aug. 9, 1999, both of which are incorporated herein by reference. Long QT Syndrome (LQTS) is a cardiovascular disorder characterized by prolongation of the QT interval on electrocardiogram and presence of syncope, seizures and sudden death,

172 Deafness
usually in young, otherwise healthy individuals (Jervell and Lange-Nielsen, 1957; Romano et al., 1963; Ward, 1964). The clinical features of LQTS result from episodic ventricular tachyarrhythmias, such as torsade de pointes and ventricular fibrillation (Schwartz et al., 1975; Moss et al., 1991). Two inherited forms of LQTS exist. The more common form, Romano-Ward syndrome (RW), is not associated with other phenotypic abnormalities and is inherited as an autosomal dominant trait with variable penetrance (Roman et al., 1963; Ward, 1964). Jervell and Lange-Nielsen syndrome (JLN) is characterized by the presence of deafness, a phenotypic abnormality inherited as an autosomal recessive trait (Jervell and Lange-Nielsen, 1957). LQTS can also be acquired, usually as a result of pharmacologic therapy. In previous studies, we mapped LQTS loci to chromosomes 11p15.5 (LQT1) (Keating et al., 1991), 7 q35-36 (LQT2) (Jiang et al., 1994) and LQT3 to 3p21-24 (Jiang et al., 1994). A fourth locus (LQT4) was mapped to 4q25-27 (Schott et al., 1995). Five genes have been implicated in Romano-Ward syndrome, the autosomal dominant form of LQTS. These genes are KVLQT1 (LQT1) (Wang Q. et al., 1996a), HERG (LQT2) (Curran et al., 1995), SCN5A (LQT3) (Wang et al., 1995a), and two genes located at 21q22-KCNE1 (LQT5) (Splawski et al., 1997a) and KCNE2 (LQT6) (Abbott et al., 1999). Mutations in KVLQT1 and KCNE1 also cause the Jervell and Lange-Nielsen syndrome, a form of LQTS associated with deafness, a phenotypic abnormality inherited in an autosomal recessive fashion.

The active agents are demonstrated to be complementary in their physiologic functions especially as these relate to the quenching of free radicals and to the support of endothelial physiology, the reduction of hyperinsulinemia and improvements in vascular health. The active components of the invention are selected for inclusion in precise combinations specifically because they improve these various conditions and physiological functions, and by so doing reduce a variety of risks associated with hearing loss and tinnitus. The resulting enhancement of general systemic vascular health, improvement in local VIII.sup.th nerve vascular health, modulation of conditions surrounding blood fluid dynamics, the consequences of hyperinsulinemia, and improvements in free radical defenses, all reduce the potential for cochlear hair cell death and VIII.sup.th nerve atrophy, and the hearing loss and possible deafness that accompany them. Excerpt(s): This application is related to United States Provisional Patent Application No. 60/178,487, filed Jan. 27, 2000, and claims all benefits legally available therefrom. Provisional Patent Application No. 60/178,487 is hereby incorporated by reference for all purposes capable of being served thereby. This invention is in the field of pharmacology and relates specifically to the improvement of clinical conditions associated with symptomatic or presymptomatic hearing loss and/or tinnitus and the reduction of risks associated with their onset. The ear of humans consists of three parts: the outer, middle and inner ear. The outer ear consists of the external ear and the auditory canal. The external ear modifies sound waves and the air-filled auditory canal conducts the sound waves to the middle ear, which consists of the tympanic membrane, or eardrum; the eustachian tube; and three tiny bones called the hammer, anvil, and stirrup. Membranes and bone surround the middle ear with the eustachian tube connecting it to the pharynx, equalizing the air pressure between the middle ear and the atmosphere.

Method for diagnosing and treating dentinogenesis imperfecta type II by using dentin sialophsphoprotein (dspp)gene and its encoding product Inventor(s): Hu, Landian; (Shanghai, CN), Kong, Xiangyin; (Shanghai, CN), Xiao, Shangxi; (Shanghai, CN), Yu, Chuan; (Shanghai, CN), Zhao, Guoping; (Shanghai, CN) Correspondence: Merchant & Gould PC; P.O. Box 2903; Minneapolis; MN; 55402-0903; US Patent Application Number: 20030180280 Date filed: March 5, 2003 Abstract: The invention has disclosed a method for diagnosis of dentinogenesis imperfecta type II (DGI-II) and/or dentinogenesis imperfecta type II with deafness (DGI-II with deafness). Said method comprises the steps of detecting the DSPP gene, transcript and/or protein in said subject and comparing it with the normal DSPP gene, transcript and/or protein to determine whether there is any variation, wherein said variation indicates that the possibility of suffering DGI-II and/or DGI-II with deafness in said subject is higher than the normal population. The present invention also discloses the method and pharmaceutical composition for treating DGI-II and/or DGI-II with deafness. Excerpt(s): This invention relates to both biological engineering and medical fields. In particular, it relates to a method of diagnosing and treating dentinogenesis imperfecta type II using human dentin sialophosphoprotein or DSPP gene and the coded product, and a pharmaceutical composition containing DSPP gene and/or protein. The odontoblasts produce the dentin, which consists in mature tooth or the tooth during tooth development phase. During dentinogenesis, the odontoblasts form dentinal tubules. Dentin cell processes in these tubules make dentin a living tissue. During the primary stage of dentinogenesis, the odontoblasts synthesize, secrete and reabsorb the dentin matrix components. Protein synthesis occurs within cells. Exocytosis and endocytosis occurs mainly in cell processes. The first material formed is unmineralized mantle dentin matrix, mainly including collagen secreted by cells and non-collagenous components. The fasciculata collagen fibers congregate to a ball structure. Due to the continual increase of new fibrils, collagen becomes closer and closer. As a result, these prophase collagen fibers change into collagen fibers. Thus predentin characterized by collagen matrix is formed. Later, the mineralization crystals gradually deposited to become dentin at some distance away from cells. The mature dentin contains more inorganic minerals than the bone. 65 wt. % of dentin are minerals, mostly hydroxyapatite crystals. Organic materials are 20%, mainly collagenous proteins and non-collagenous proteins. These collagens offer braces to the deposition of hydroxyapatite plate like crystalline.

Patents 175
Abstract: The present invention relates to protein-protein interactions involved in deafness or in hearing disorders and/or diseases. More specifically, the present invention relates to complexes of polypeptides or polynucleotides encoding the polypeptides, fragments of the polypeptides, antibodies to the complexes, Selected Interacting Domains (SID.RTM.) which are identified due to the protein-protein interactions, methods for screening drugs for agents which modulate the interaction of proteins and pharmaceutical compositions that are capable of modulating the proteinprotein interactions. Excerpt(s): This application claims priority from U.S. provisional application No. 60/299,848 filed Jun. 21, 2001 and European application No. 02290277.9 filed Feb. 5, 2002. Most biological processes involve specific protein-protein interactions. Proteinprotein interactions enable two or more proteins to associate. A large number of noncovalent bonds form between the proteins when two protein surfaces are precisely matched. These bonds account for the specificity of recognition. Thus, protein-protein interactions are involved, for example, in the assembly of enzyme subunits, in antibodyantigen recognition, in the formation of biochemical complexes, in the correct folding of proteins, in the metabolism of proteins, in the transport of proteins, in the localization of proteins, in protein turnover, in first translation modifications, in the core structures of viruses and in signal transduction. General methodologies to identify interacting proteins or to study these interactions have been developed. Among these methods are the two-hybrid system originally developed by Fields and co-workers and described, for example, in U.S. Pat. Nos. 5,283,173, 5,468,614 and 5,667,973, which are hereby incorporated by reference. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Mutation within the connexin 26 gene responsible for prelingual non-syndromic deafness and method of detection Inventor(s): Denoyelle-Gryson, Francoise; (Sceaux, FR), Guesdon, Jean-Luc; (Sevres, FR), Marlin-Duvernois, Sandrine; (Colombes, FR), Petit, Christine; (Le Plessis-Robinson, FR), Weil, Dominique; (Paris, FR) Correspondence: Finnegan, Henderson, Farabow, Garrett & Dunner; Llp; 1300 I Street, NW; Washington; DC; 20005; US Patent Application Number: 20030170676 Date filed: October 23, 2002 Abstract: A purified polynucleotide having a chain of nucleotides corresponding to a mutated sequence, which in a wild form encodes a polypeptide implicated in hereditary sensory defect, wherein said mutated purified polynucleotide presents a mutation responsible for prelingual non-syndromic deafness selected from the group consisting of a specific deletion of at least one nucleotide. Excerpt(s): The present invention concerns a mutation responsible for autosomal prelingual non-syndromic deafness and a method for the detection of this hereditary sensory defect for homozygous and heterozygous individuals. The invention concerns more particularly a specific deletion of at least one nucleotide in the connexin 26 (Cx 26) gene and especially in a guanosine rich region, notably between the nucleotides 27 and 32. The invention is also directed to the use of polynucleotide, or fragments thereof, for example as tools useful for the in vitro detection of a mutation of a gene belonging to the Cx26 gene family.

thousand in developed countries (Morton N E. Genetic epidemiology of hearing impairment. In Genetics of hearing impairment. (The New York Acad Sci, New York 1991; 630:16-31). It is a major handicap as it impedes language acquisition. According to studies performed in a U.S. population of children with non-syndromic (isolated) prelingual deafness and in whom an obvious environmental cause has been excluded, it is estimated that up to two-thirds of the cases have a genetic basis (Marazita M L, Ploughman L M, Rawlings B, Remington E, Arnos K S, Nance W E. Genetic epidemiological studies of early-onset deafness in the U.S. school-age population. Am J Med Genet 1993; 46:486-91). These forms are mainly sensorineural and are almost exclusively monogenic. The major mode of inheritance is autosomal recessive (DFNB), involving 72% to 85% of cases, this fraction increasing to 90% when only profound deafness is taken into account.

The present invention thus provides methods of improving the outcome of subjects treated with cisplatin. Excerpt(s): This application claims priority to U.S. provisional patent application serial No. 60/349,801, filed Jan. 17, 2002 and U.S. provisional patent application serial No. 60/351,662, filed Jan. 25, 2002. The present invention relates to compositions and methods for the protection and restoration of hearing. In particular, the present invention relates to methods and compositions for the prevention of chemical (e.g., cisplatin) induced deafness. Hearing impairment is the United State's number one disability. It has been estimated to compromise the quality of life and communication in more than 30 million Americans, and approximately 1 billion individuals worldwide. With the increase in longevity in life and the association of hearing impairment with aging, this disability is increasing in incidence and prevalence. In children, it severely affects education and future employment opportunities. In a working individual, it compromises the quality of life, job satisfaction, and productivity; and in the elderly, it leads to isolation and increased medical costs.

System and method of teleconferencing with the deaf or hearing-impaired Inventor(s): Basson, Sara H.; (White Plains, NY), Epstein, Edward Adam; (Putnam Valley, NY), Fairweather, Peter G.; (Yorktown Heights, NY), Kanevsky, Dimitri; (Ossining, NY) Correspondence: Paul J. Farrell; Dilworth & Barrese, Llp; 333 Earle Ovington Boulevard; Uniondale; NY; 11553; US Patent Application Number: 20020069069 Date filed: December 1, 2000 Abstract: A system and method is provided for real time teleconferencing, where one of the participants is deaf or hearing-impaired. In one aspect of the system and method, each participant has an Automatic Speech Recognition (ASR) system and a chat service system, such as AOL Instant Messenger.TM. Each participant may have a different type of ASR system, as well as a different type of chat service system. It is not necessary that the deaf or hearing-impaired participant have an ASR system. For each participant, the participant's ASR system transcribes the speech of the participant and provides it to the participant's chat service system, which translates the transcribed text into the chat service message in the format of the participant's chat service system. An Integration Server receives all the participant's chat messages, which have various formats, and translates them into the format used by the chat service system of the deaf or hearingimpaired participant, thus allowing her to see the transcribed text of the conversation between the other participants. In addition, the deaf or hearing-impaired participant inputs text to her chat service system, which creates a formatted message text. The Integration Server receives this formatted chat message and translates it into the formats of the remaining participant's chat service systems, so that the remaining participants see the comments of the deaf or hearing-impaired participant. In other aspects, the teleconferencing system and method is used to connect disparate chat service systems, without necessarily including a deaf or hearing-impaired participant. Excerpt(s): This invention relates to a system and method for providing the deaf or hearing impaired to participate in a teleconference in general, and, in particular, to a system and method that provides a platform which allows various Automatic Speech Recognition (ASR) systems to communicate over various chat messenger systems so that a deaf or hearing-impaired person may receive a transcribed text of the teleconference. Presently, there are several methods for the deaf and hearing-impaired to interpret those speaking to them. One method is having a live interpreter, who listens to the conversation and translates the spoken words into sign language, and vice-versa. Another method is having a live stenographer, who listens to the conversation and types the spoken words so that they may be viewed in real-time and responded to. Yet another method is a stenographic, or Automatic Speech Recognition (ASR), program, which transcribes the spoken words in the same manner as a live transcriber. However, teleconferencing presents particular problems to the deaf and hearing impaired. The logistics of providing one or more live interpreters or translators would be both complex and expensive. Although using a computer program, i.e. ASR, is cheaper than an interpreter/stenographer, ASR has its own problems. If the ASR program is speakerdependent, it requires a certain amount of time to be trained to the intonations of each individual speaker. This would require multiple speaker profiles to be stored in order that the ASR program could deal with the audio input from the multiple participants in a teleconference. These profiles would use up more and more storage space. The ASR system itself would need to be more complex, because it would need to deal with several different audio streams being received simultaneously.

Transcanal, transtympanic cochlear implant system for the rehabilitation of deafness and tinnitus Inventor(s): Boylston, Byron Lee; (Woodstock, GA), Goldsmith, Manning Miles; (Savannah, GA) Correspondence: Jason A. Bernstein; Bernstein & Assoicates, P.C.; 6600 Peachtree Dunwoody Road, N.E.; Embassy Row 400, Suite 495; Atlanta; GA; 30328-1649; US Patent Application Number: 20020099421 Date filed: January 22, 2002 Abstract: A transcanal, transtympanic cochlear implant system for implantation comprising a molded insert for removable positioning in the auditory canal of the human ear and an insulated receiver coil, preferably in a generally circular or looped form, where the receiver coil receives electromagnetic signals, in a first embodiment, or radio frequency signals, in a second embodiment, through inductive coupling to a solenoid coil within the molded insert. Excerpt(s): This application claims benefit of copending provisional patent application No. 60/263,600 filed Jan. 23, 2001, entitled TRANSCANAL COCHLEAR IMPLANT, which is incorporated herein. The present invention is directed to the field of cochlear implants for patients with hearing impairment and/or tinnitus, more particularly to a transcanal, transtympanic cochlear implant system that requires a minimum of surgical intrusion that may be performed at a physician's office under local anesthesia. The present invention relates to a transcanal, transtympanic cochlear implant system ideally suited for those profoundly deaf, where conventional amplifying hearing aids are of limited or no value to those suffering the hearing impairment. That is to say, with maximum gain delivered by the most powerful hearing aids, these profoundly deaf individuals cannot hear sound and hence cannot discriminate and understand speech. In addition, there are an estimated 200-300 million people who have various patterns of severe sensorineural hearing loss, which are imperfectly rehabilitated via hearing aids. An example of such is so called "ski-sloped hearing loss," where there is near normal hearing in the low to middle frequency range, but the hearing drops out dramatically in the higher frequencies. For these types of hearing loss, amplification is ineffective, because the cochlea cannot perform its transductive function of converting the mechanical energy of sound to the electrical current, which is ultimately perceived as sound by the brain. The inner ear structures responsible for this transductive function are known as hair cells, and the electrical currents, which they produce in response to the mechanical stimulation by sound, are known as cochlear microphonics. When these hair cells are sufficiently damaged in the above mentioned scenarios, no amount of amplification will be effective. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Summary: It is estimated that there are currently 1.9 million deafened people living in North America, people who could once hear naturally or with amplification but who have become deaf and are now unable to rely on hearing to comprehend spoken information. This book addresses the process of adjustment to, and acceptance of, deafness as an adult. The authors demonstrate that deafness is not merely a medical condition; it is a social disability that affects the person, the family, the social circle, and the work group. By describing the psychosocial experience of acquired deafness as a process of adjustment, the authors demonstrate that acceptance of deafness is a process with practical, social, and emotional implications. The authors also provide a guide to self help techniques of proven value to deafened people. Drawing on their own experiences as deaf professionals, the authors explore questions such as how deafness occurs, how relationships (professional and personal) can be affected by progressive deafness, and how and where to find peer support. Section 1 describes the process of adjustment, while Section 2 offers a practical guide to a successful method of establishing a self help support network, with reference to such organizations as the Association of Late Deafened Adults. The book combines medical background,

In the process, the author examines the different functions that folklore serves in the community: folklore acts as a metaphor for the group's experience; transmits group customs, values, and behavior norms; serves as an educational tool for specific

The author also demonstrates that folklore serves to provide avenues for creative expression and to validate the worth of the group and their culture. 178 references. (AA-M). •

PRICE: $24.95 plus shipping and handling. ISBN: 0886293510. Summary: This textbook is a study of the political socialization of children who are deaf. The author notes that while the battle lines have been drawn by the proponents of oralism versus manualism and their hearing supporters, two linguistic dilemmas facing Deaf people remain constant: a conscious choice is always made for them as to the way they will be taught, and either method of language acquisition results in a form of marginalization. Five chapters cover political socialization and marginalization, an historical overview of the deaf, socializing agencies, a comparative group study, and reflections and recommendations. Specific topics include socialization and political socialization, theoretical frameworks of political socialization, theories of political marginalization, neglect of the disabled, agencies for examination, history of the Deaf, the languages of the Deaf classroom, mainstreaming, Deaf culture, the family, power relationships and the pattern of marginalization, language choice as political choice, the schools and peer group, role models, social maturation and peer groups, quality and ends of education, the cochlear implants rally, family relations and language or identity factors, and language as a tool of Deaf political socialization. The text concludes with a bibliography of additional resources. 193 references.

This chapter on hearing loss and deafness is from a manual for professionals working with people with disabilities. The author stresses that it is important to make distinctions between deafness, hearing impairment, and being hard of hearing; definitions for each category are provided. The author then discusses issues that affect living with hearing loss, including the extent of
206 Deafness
the loss, prelingual versus postlingual hearing loss, and associated consequences such as difficulty in locating sound, problems with tinnitus (ringing or buzzing in the ears), and dizziness or balance problems. The author considers the presence of other disabilities with hearing loss and the options for communicating with people who have hearing loss, including oral communication, manual communication, and written communication. Other topics covered are the Deaf community, personal adjustment to a hearing loss, sexuality, parenting, family, community living, access to community activities and services, education, employment, appropriate interpersonal language and behavior, strategies for interaction, anatomy of the ear, the mechanism of hearing, the causes of hearing loss, incidence and prevalence, diagnostic considerations, support services, hearing aids and other assistive devices, and additional costs that may be incurred by someone with a hearing loss.

[email protected]. Website: www.utpress.utoronto.ca. Price: $21.95 plus shipping and handling. ISBN: 0802083730. Summary: Late deafness can be defined as hearing loss in people who could once hear naturally or with amplification but who have become deaf and are now unable to rely on hearing to comprehend speech. This chapter describing late deafness is from a book that addresses the process of adjustment to, and acceptance of, deafness as an adult. The authors demonstrate that deafness is not merely a medical condition; it is a social disability that affects the individual, the family, the social circle, and the work group. By describing the psychosocial experience of acquired deafness as a process of adjustment, the authors demonstrate that acceptance of deafness is a process with practical, social, and emotional implications. Written predominantly in a question and answer format, this chapter covers hearing evaluation and measurement of hearing loss, how loss of a few sounds affects speech comprehension, the anatomy and physiology of the ear and hearing, the causes of hearing loss and deafness, medical classifications of deafness, the prevalence of different types of hearing loss, and the practical definitions of hearing loss and its impact on every day living. Comments from the authors' experiences are provided in sidebars throughout the chapter. 3 figures. 1 table.

Common Refractive Errors (Ametropias) and Deafness Source: in Johnson, D.D. Deafness and Vision Disorders: Anatomy and Physiology, Assessment Procedures, Ocular Anomalies, and Educational Implications. Springfield, IL: Charles C. Thomas Publisher, Ltd. 1999. p. 224-264. Contact: Available from Charles C. Thomas Publisher, Ltd. 2600 South First Street, Springfield, IL 62794-9265. (800) 258-8980 or (217) 789-8980. Fax (217) 789-9130. PRICE: $74.95 plus shipping and handling. ISBN: 039806945X. Summary: Refractive errors are functional optical (eye) defects in which the parallel light rays from the environment, after passing through the eye's transparent substances, are not brought to a sharp focus precisely on the retina when the eye is unaccommodated; hence, the retinal images are blurred. This chapter on refractive errors (ametropias) is from a textbook written to help students preparing for work in the field of deafness to understand and incorporate an awareness of vision disorders in the deaf population. The information concerning the congenital anomalies, functional defects, and pathologic ocular conditions most often found within a deaf student population was obtained from eleven years of research unobtrusively conducted within the NTID Eye and Ear Clinic between August 1984 and May 1995 (at the National
208 Deafness
Technical Institute for the Deaf, one of the eight colleges of the Rochester Institute of Technology). This chapter deals specifically with those refractive errors common in this population: myopia (nearsightedness), hyperopia (farsightedness), astigmatism, or a combination thereof. For each condition, the author provides definitions and general comments, classification issues, etiology, and the statistics for the condition in the NTID population. Refractive errors were by far the most common ocular disorders found among NTID deaf students, ranging from approximately 40 percent of the total population of students (n = 3190) entering NTID to about 85 percent of those 756 students seen in the NTID Eye and Ear Clinic. 12 tables. 57 references. •

Summary: Teaching children who are deaf to speak is a formidable task for both teacher and child. In this chapter, from a text on profound deafness and speech communication, the author discusses the use of sensory aids for teaching speech to children who are deaf. The pedagogical issues involved in teaching speech are used as a framework within which to examine the development, evaluation, and use of existing technology. The author examines the issues inherent in developing speech in children with minimal auditory capability; describes pedagogical issues associated with using sensory aids for speech training with deaf children; examines existing technologies and the evidence for their clinical efficacy; and discusses future needs. 2 figures. 62 references.

Summary: This article reports on a study in which the clinical course of tinnitus was examined in 90 patients with idiopathic sudden deafness (SD) and this was compared with the recovery of hearing. The article is from a lengthy document that reprints the proceedings of the Sixth International Tinnitus Seminar, held in Cambridge, United Kingdom, in September 1999 and hosted by the British Society of Audiology. In this study, approximately 50 percent of patients experienced persistent tinnitus during the first week after the onset of SD and this decreased gradually by approximately 10 percent beyond the fifth week. In contrast, the proportion of tinnitus free patients increased from 20 to 40 percent during the same period. The tinnitus with a pitch matching low frequency or broad band noise was more frequently observed in SD than in other otological diseases. Approximately 60 percent of the patients experienced a change in pitch or timbre of tinnitus over time. In the groups with a good hearing recovery, decreasing and temporally increasing types of loudness change were predominant, whereas in patients with a poor hearing recovery, fluctuating, constant, and tinnitus free types were most frequently observed. 4 figures. 1 reference.

PRICE: $34.95 plus shipping and handling. ISBN: 039805861X. Summary: This chapter addresses unresolved issues in the provision of mental health services to people who are deaf. The authors note that because effective communication between the mental health professional and the consumer is critical to the counseling process, many of the issues presented in this chapter are especially pertinent in situations involving individuals who use American Sign Language (ASL) as their primary mode of communication. Topics covered include barriers to the provision of accessible and appropriate mental health services; issues related to establishing rapport and a therapeutic alliance in initial interviews; issues impacting the use of interpreters in mental health settings; and issues impacting the delivery of mental health services to deaf people who are members of racial or ethnic minority groups. The authors stress that people who are deaf should be able to access as broad a continuum of programs and services as is available for people who hear. Numerous case examples are presented to illustrate the concepts discussed. 41 references. (AA-M).

ISBN: 0780802411. Summary: This chapter from a Genetic Disorders Sourcebook covers hereditary hearing loss and deafness. Several hundred genes are known to cause hereditary hearing loss and deafness. The genetic forms of hearing loss are diagnosed by otologic, audiologic, and physical examination, family history, ancillary testing (such as computed tomography, or CT, examination of the temporal bone), and DNA based testing. DNA based genetic tests are available for the diagnosis of branchiootorenal (BOR) syndrome, Pendred syndrome, dilated vestibular aqueduct syndrome, DNFB1, and DFNB4; testing for deafness causing mutations in the GHB2 gene (connexin 26) plays a prominent role in diagnosis and genetic counseling. The authors cover definitions, categories of hearing loss, syndrome hearing loss, manners of inheritance, Usher syndrome, Pendred syndrome, Jervell and Lange Nielsen syndrome, Waardenburg syndrome, BOR syndrome, Stickler syndrome, neurofibromatosis, Alport syndrome, genetic counseling, special issues in counseling Deaf persons, and patient care management. The chapter concludes with a listing of resources through which readers can obtain additional information. •

Summary: This chapter is from a text that explores research on atypical communication and language development as a source of knowledge about how children become accomplished communicators. The authors of this chapter discuss their studies of advances in reading and writing under multimedia literacy instruction in children with disabilities. The children in the studies ranged in age from 5 year olds who are beginning to read to 10 to 16 year olds with serious delays in reading and writing skills. Their disabilities included autism, deafness, motor disabilities, dyslexia, and attention deficit hyperactivity disorder (ADHD). Regardless of age and disability, these children worked with multimedia computer software designed to facilitate skills in the text mode by patterning text sentences together rapidly with other media channels, including graphics, voice, and sign language. The first section in the chapter provides the theoretical basis for the multimedia procedures, including the application of Rare Event Learning (REL) theory. The next section reviews results of field research for children's advances in reading and writing and for related teacher and child variables. Most of the results involve children with deafness and other hearing impairments and children with autism. 6 tables. 75 references.

Website: www.agbell.org. Summary: This chapter is from a text that provides information on the language, speech, and social emotional development of very young children who are deaf or hard of hearing. In this chapter, the authors report on a study that examined receptive vocabulary scores on the Words and Gestures subtest of the MacArthur Communicative Development Inventory (CDI); the study population was a group of 8 to 22 month old infants and toddlers with hearing loss (n = 168). Results of analyses demonstrated significant correlations between the children's receptive vocabulary scores and other CDI language subscales, as well as other measures of language, aspects of nonverbal cognition, and an assessment of symbolic play skills. Demographic variables of the sample (including gender, mode of communication, age of identification, disability status, ethnicity, level of maternal education, and degree of hearing loss) were found not to be significantly correlated with children's receptive vocabulary scores. Normative data for receptive vocabulary development, based on the CDI, are presented so that 8 to 22 month old deaf or hard of hearing children with hearing parents can be compared with their peers. The authors note that the majority of children in this study were identified with hearing loss before 6 months. It is possible that, though still delayed in comparison with normal hearing children, the average receptive vocabulary development of this group is more advanced than would have been expected prior to development of universal newborn hearing screening programs. 2 figures. 6 tables. 57 references. •

Summary: This chapter is from a textbook that offers a comprehensive study of the acquisition of English literacy skills in children and adolescents with severe to profound hearing impairment. In this chapter, the author offers some reflections and directions concerning the development of literacy and literate thought in children and youth who are deaf. If English text based literacy is a major, realistic goal, it is argued that educators need to decide if the basic fundamentals of literacy can be developed by students with severe to profound hearing impairment, especially in light of what is known about literacy development and instruction. The chapter reemphasizes several issues relative to the development of literacy and literate thought: the interrelations of metatheory, theory, research, and practice; the reciprocal relations between word identification and comprehension and between the conversational and written forms of a phonetic language such as English; and the contributions of a well and early developed language to the subsequent development of literate thought. 4 references.

PRICE: $74.95 plus shipping and handling. ISBN: 039806945X. Summary: This chapter is from a textbook written to help students preparing for work in the field of deafness to understand and incorporate an awareness of vision disorders in the deaf population. This chapter discusses the educational implications and vision problems of the deaf, focusing on the ancillary clinic and educational support services. Information within the book concerning the congenital anomalies, functional defects, and pathologic ocular conditions most often found within a deaf student population was obtained from eleven years of research unobtrusively conducted within the NTID Eye and Ear Clinic between August 1984 and May 1995 (at the National Technical Institute for the Deaf, one of the eight colleges of the Rochester Institute of Technology). The first part of the chapter deals with the treatment plans requested by the NTID consulting ophthalmologists as a result of their findings. Treatment options discussed include observation and identification, visual field tests, new prescription for glasses, personal and family counseling, maintain same prescription for glasses, prescription for safety glasses, obtain previous records, get fundus or disc photographs, get electroretinograms (ERG), off campus diagnostic referral, get low vision evaluation (LVE), determine RP status, see contact lens specialist, obtain prescription for medications, declare legal blindness, and get Amsler grid test. The second portion of the chapter provides suggestions for modification of the educational environment or use by the student of special low vision aids to more adequately insure academic success for those deaf students with noncorrectable visual problems. These educational support services may include use of low vision aids (LVAs) such as magnifying lenses in spectacles, hand held or stand magnifiers, telescopic devices, and closed circuit television (CCTB) reading devices. Other services may include preferential seating or classroom modifications such as enlarged print on transparencies, nonglare lighting, and enlarged print passouts of the instructor's lecture outline. The author presents a number of case illustrations to demonstrate how these educational modifications are used by students at NTID to enhance their chances for academic success. 5 tables. 15 references. •

Summary: This chapter on cochlear implants and tactile devices for students with profound deafness is from a textbook that brings together experts from all disciplines to present ideas on how to provide help for school children with auditory disorders. The basic tenet of audiological management for children with hearing impairment is to provide amplification as soon as possible to promote communication skills. However, for those children who do not receive benefit from conventional amplification, the use of cochlear implants and tactile devices may be indicated. Topics covered include determining the need for cochlear implants or tactile aids; safety, effectiveness, and labeling, including the role of the Food and Drug Administration (FDA); features and technology of a cochlear implant; cochlear implant candidacy requirements; risks and

Summary: This chapter on deafness and alcohol abuse is from a book intended to focus attention on the problem of substance abuse in the Deaf community. It attempts to help people affected by addiction, and provide preventive information and incentives to preclude the development of alcoholism and substance abuse in the next generation. Originally published as the author's dissertation, the book states that up to 35 percent of people with significant hearing impairment have abused substances, including alcohol. This is almost double the estimated rate of comparable abuse among people who do not have impaired hearing. This chapter presents a broad overview on alcoholism as it relates to deafness. The author discusses basic information about alcoholism; reviews both short and long term physical, mental, emotional, and social effects of alcohol abuse; outlines current thought regarding the etiology and epidemiology of alcoholism, including predisposing influences, such as genetics; discusses sociocultural and psychological interweaving factors which can contribute to or maintain alcohol abuse; and provides a listing of some variables that may influence an individual's willingness to seek treatment for alcohol addiction. 2 tables.

Summary: This chapter on the assessment of speech intelligibility in people who are deaf is from an audiological rehabilitation monograph from the Academy of Rehabilitative Audiology. Major themes concern the relative importance of factors affecting speech intelligibility, the relationship of physical speech parameters to perceptual speech intelligibility measures, and the reliability and validity of various approaches to measuring speech intelligibility. The authors suggest future research directions, predicated on the implications of current research, for computer-based measurement of both physical speech parameters and their ultimate use for speech intelligibility estimation. The research findings discussed in this chapter indicate the importance of careful attention to methodological issues in the assessment of speech intelligibility. 33 references. (AA-M). •

[email protected]. PRICE: $89.00 plus shipping and handling. ISBN: 0865778825. Summary: This chapter on the long term effects of deafness and chronic electrical stimulation of the cochlea is from a book that incorporates original chapters on relevant topics with related papers. These papers were presented at the Fifth International Cochlear Implant Conference held in New York, in May, 1997. The book provides professionals involved in the field of cochlear implants with a comprehensive reference text. All aspects of implantation are covered including the effects of electrical stimulation, processing capabilities, preoperative criteria, medical, surgical and radiological issues, results and postoperative programming, rehabilitation, and education. The authors of this chapter note that, with the number of very young children now receiving cochlear implants, it is important to determine the consequences of implantation and stimulation with the highly abnormal input delivered by a cochlear implant upon the deafened, developing auditory system. The authors report on their studies that have been conducted in cats that are neonatally deafened by administration of an ototoxic drug. The deafened animals receive implants unilaterally at the time of weaning, and the electrical signals delivered by the implant provide the initial and sole input to the developing auditory system. The authors summarize the results of research on the morphologic and physiologic consequences of chronic electrical stimulation in these neonatally deafened animals and discuss some of the implications relevant to pediatric cochlear implants. 7 figures. 54 references.

PRICE: $99.50 plus shipping and handling, unless prepaid. ISBN: 3805560958. Summary: This chapter, from a text on cochlear implants in children, reports on an investigation to study the effects of early implantation (shorter length of deafness) on speech recognition in children who are congenitally/prelingually deaf. The authors note that the majority of studies to date have reported results on deaf children with a mean age at time of implantation of approximately 6 years. In this study, the authors included 14 children who received the Nucleus multichannel cochlear implant and have used the device for at least 2 years. None of the subjects exhibited more than pattern perception with conventional amplification and a plateuing of development of auditory and linguistic skills was evident prior to implantation. The authors report that all subjects in this study demonstrate open-set speech recognition, use oral/aural communication, attend age-appropriate nursery or mainstream schools, and continue to improve over time. They also briefly discuss the additional variables that may impact on the success of the cochlear implant, including adequate device programming, remapping, rehabilitation and training, and level of parental involvement. 2 figures. 3 references.

Summary: This introductory chapter is from a book that offers an overview of cued speech, the use of hand cues with speech that permits the deaf child to learn the English language. The book includes information and advice for parents who have decided to use Cued Speech with a child who is deaf or hard of hearing, or are considering doing so. This chapter is addressed to parents who have just learned that they have a hearing impaired child. The authors feel that such parents should begin by taking a careful look at what typically happens to parents of a deaf child and what typically happens to the child. At the same time, the authors stress that it does not have to be this way. The authors discuss the effects of inadequate communication, the implications of different methods of communication, the emotional stages that parents go through, problems associated with post-lingual (after some language has been achieved) hearing loss, and typical performance of deaf children. The authors conclude that most hearing impaired children have speech and speechreading skills inadequate for effective communication with the general public, and they fall (and remain) far behind their hearing peers in language, reading, and other academic areas. The authors end the chapter by noting that Cued Speech offers a solution to these problems.

Summary: This lengthy chapter is from a textbook written to help students preparing for work in the field of deafness to understand and incorporate an awareness of vision disorders in the deaf population. This chapter discusses common ocular disorders. Information within the book concerning the congenital anomalies, functional defects, and pathologic ocular conditions most often found within a deaf student population was obtained from eleven years of research unobtrusively conducted within the NTID Eye and Ear Clinic between August 1984 and May 1995 (at the National Technical Institute for the Deaf, one of the eight colleges of the Rochester Institute of Technology). This chapter deals specifically with those eleven common visual pathologies and aberrant visual conditions most often encountered among the young and more chronologically mature deaf adult students within the NTID college population. The author also hopes to promote an awareness of those vision problems which are also likely to be found in greater numbers within the deaf population in general. Failure to identify and attend to these problems may not only impact on the learning process, but on communication, mobility, recreation, social interaction, and vocational pursuits as well. The conditions covered are rubella oculopathy, strabismus, amblyopia, inherited color vision deficiency, retinitis pigmentosa (Usher syndrome), cataracts or aphakia, nystagmus, microphthalmos, glaucoma, ocular albinism, and ptosis (blepharoptosis). The chapter demonstrates that a large number of deaf people have concomitant visual problems, many of which are noncorrectable or progressive in nature. 43 tables. 130 references.

AIDS in the Deaf Community/Deaf in the AIDS Community : Creating Partnerships Contact: University of California San Francisco, Center on Deafness, 3333 California St Ste 10, San Francisco, CA, 94118, (415) 476-4980. Summary: This video discusses how organizations for deaf persons and health service providers and program staff can work together to improve care for deaf people with the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS). The video states that in many cities there is a lack of services available to deaf persons with HIV/AIDS, thus making it difficult for providers or program staff to communicate effectively with patients or clients. This lack of services has also made it more difficult to pass on new information concerning HIV prevention and treatments to the deaf community as a whole. The video makes recommendations that are designed to help programs without services specifically for deaf persons to communicate more effectively with their non-hearing clients. The video provides guidelines for the viewers about how they can provide for the deaf in their existing programs and services. The video examines the impact of HIV/AIDS on the deaf community in the United States (US), and the reasons why some deaf people may be reluctant to use services or programs, even those offered specifically for them. It advises the viewers on how health care providers and HIV/AIDS programs can create partnerships with local deaf organizations to overcome these communication, education, attitudinal, and treatment barriers.

Summary: This video program depicts a satellite teleconference, held in March 1998, on 'Implementing The Americans with Disabilities Act in Postsecondary Institutions Serving Deaf and Hard of Hearing Students.' The program features Jeanne M. Kincaid, a specialist in disability and law in education, with three other panelists, Dr. Edwin Franklin, Marta Belsky, and Dr. Frederick Schroeder. The conference was hosted by the Midwest Center for Postsecondary Outreach, one of four national regional centers that comprise the Postsecondary Education Programs Network (PEPNet) that are available to help educators who are working with people who are deaf or hard of hearing. These centers work primarily at the institutional level to increase and enhance postsecondary educational opportunities for individuals who are deaf and hard of hearing. The program discusses how to find, evaluate, manage and budget for interpreting services, the role of vocational rehabilitation in providing auxiliary services in postsecondary educational settings, and techniques that can be used to increase the diversity of a particular campus by including deaf or hard of hearing students. The panelists answer questions from the teleconference and studio audience. Dr. Kincaid emphasizes that there are ways to effectively manage the requirements of the ADA and Section 504 that are cost effective and yet provide quality services to the students. The information provided should not be considered legal advice, but should merely serve as guidance in assisting providers, colleges, universities at large, and others in understanding the obligation institutions of higher learning have to serve students who are deaf and hard

Web site: http://professional.asha.org/news/. PRICE: Available free online at http://professional.asha.org/news/f021203.cfm. Summary: Theory of mind refers to the ability of a child to understand that people have different thoughts, wants, and beliefs, and a person's behavior can be predicted based on what he or she thinks or believes. Although children develop an understanding of theory of mind at roughly four years of age, research has shown that deaf children can experience significant delays in understanding the concept. This article discusses the concept of theory of mind in regard to deaf children, and reports the results of an NIDCD-funded study that investigates whether deaf children are equally delayed in their theory-of-mind skills for tasks that employ language as well as tasks that do not.

Implications of Delay in Detection and Management of Deafness Source: Educational Audiology Review. 15(4): 10-15. Fall 1998. Contact: Available from Educational Audiology Association. 4319 Ehrlich Road, Tampa, FL 33624. (800) 460-7322. Website: www.edaud.org. Summary: This article, first published in the early 1990s, reviews the implications of delay in the detection and management of deafness in children. The author notes that, although there may be controversies in the field of education of the hearing impaired, nearly everyone involved with children with hearing loss can agree on the important role of early detection and intervention, regardless of method used. The author reviews the typical progression of parental concern, general physician assessment of the child, dismissal of the concern, then finally referral of the child for intervention, often after the child's abnormal auditory and verbal development becomes more apparent. The end result of this sequence is that the average child with hearing loss still does not receive his or her first hearing aid until age two or older. The author then discusses the possible consequences of this delay, including the devaluation of hearing and attitudes toward hearing impairments in the U.S. Topics include self-acceptance, auditory sensory deprivation, auditory self-monitoring, the effects of delay in intervention on early linguistic development, and psychosocial implications. The author reiterates that children with hearing loss who are enrolled in early management programs demonstrate superior linguistic skills compared to those who are enrolled later.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for deafness. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with deafness. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Summary: The provision of notetaking services is crucial for most deaf and hard of hearing students at the postsecondary level in classes designed for students with normal hearing. This report on notetaking is one in a series intended to assist postsecondary institutions in developing and maintaining special services of quality as needed by this population. Each of the reports emphasizes the need to remember that deaf and hearing impaired persons as individuals first, and their needs and wishes for special services and other accommodations will vary, as it does in any other population. This report is intended to clarify needs for notetaking services and ways of providing these services. The authors discuss training, supervision, and the responsibilities of those involved in the provision of notetaking, along with suggested policies and procedures for assuring a useful and efficient service to students. Topics include listening and the process of good notetaking, general suggestions for the individual taking notes, what to look for in a good notetaker, the notetaker Code of Ethics, policies regarding the notetaking process (including class assignments, attendance, punctuality, attire, supervision, sharing of notes, evaluations, photocopies versus NCR paper, payroll and pay scale, recruitment, selection, and student grievance processes). Topics also include training notetakers, the role of the notetaker coordinator, paid versus volunteer notetaking, student responsibilities, faculty responsibilities, applications of technology in notetaking (including computer assisted realtime captioning or CART), and relevant laws and regulations. One appendix reprints the Notetaker's Code of Ethics; another offers sample rating and evaluation forms. 13 references.

Journey Through Late Deafness: Results of a Focus Group Study Source: San Diego, CA: California School of Professional Psychology. 1997. 21 p. Contact: Available from California School of Professional Psychology Rehabilitation Research and Training Center on Mental Health for Persons Who are Hard of Hearing or Late Deafened. 6160 Cornerstone Court East, San Diego, CA 92121. E-mail:
[email protected]. PRICE: Single copy free. Summary: This document reports on the results of a series of focus groups with late deafened adults and their family members. Questions posed during these groups attempted to get to the heart of significant issues related to hearing loss that strikes in adulthood. Issues include personal adjustment, employment barriers, communication issues, family dynamics, and social factors. This report outlines the process of the focus group study, provides readers with the significant findings of that process, gives recommendations and suggestions regarding future research, and describes a model service delivery system developed with consumer input. The number one concern reiterated by both individuals who were late deafened and family members was communication difficulty: at home, in the workplace, and with friends and other family members. Other concerns of people the focus groups included: dealing with depression and withdrawal, learning coping skills, finding information about deafness, staying positive, socializing, issues of independence, and intimacy. The report concludes with a recommendation for a proposed Individual and Family Life Center for Late Deafened adults. The center would be research-based and would serve a regional area. The initial center would conduct research and provide training in the area of late deafness, and

Report on Tutoring Deaf and Hard of Hearing Students Source: Rochester, NY: Northeast Technical Assistance Center, National Technical Institute for the Deaf, Rochester Institute of Technology. 1997. 15 p. Contact: Available from PEPNet Resource Center. National Center on Deafness, California State University, Northridge, 18111 Nordhoff Street, Northridge, CA 913308267. Voice/TTY (888) 684-4695 or (818) 677-2611. Fax (818) 677-4899. Website: www.pepnet.org. PRICE: Single copy free. Summary: This report on tutoring deaf and hard of hearing students is one in a series intended to assist postsecondary institutions in developing and maintaining special services of quality as needed by this population. Each of the reports emphasizes the need to remember that deaf and hearing impaired persons as individuals first, and their needs and wishes for special services and other accommodations will vary, as it does in any other population. As discussed in this report, tutoring generally refers to the traditional practice of meeting periodically or as the need arises to help a given student acquire or strengthen a particular knowledge or skill. Tutoring ranks with interpreting and notetaking as one in a triad of fundamental academic support services for deaf and hard of hearing students at the postsecondary level, particularly in mainstream settings. The report addresses the indications for tutoring in this population, and discusses the provision of tutoring services. Other topics covered include how to identify students in need of tutoring, how to make students aware of tutoring services, the selection and training of tutors, the expectations of participants from tutoring sessions, quality in tutoring deaf students, tutoring for basic skills and general courses, tutoring support for written assignments, and tutoring formats. Other considerations in providing tutoring services include location, environment, resources, rewarding tutors, and ethical standards. The report concludes with a brief discussion of evaluating the success of a tutoring program, including the use of models and standards. One appendix includes a sample tutoring agreement form and an evaluation form. 1 table. 12 references.

staff.22 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.23 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.

The Genome Project and Deafness In the following section, we will discuss databases and references which relate to the Genome Project and deafness. Online Mendelian Inheritance in Man (OMIM) The Online Mendelian Inheritance in Man (OMIM) database is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere. OMIM was developed for the World Wide Web by the National Center for Biotechnology Information (NCBI).24 The database contains textual information, pictures, and reference information. It also contains copious links to NCBI’s Entrez database of MEDLINE articles and sequence information. To search the database, go to http://www.ncbi.nlm.nih.gov/Omim/searchomim.html. Type “deafness” (or synonyms) into the search box, and click “Submit Search.” If too many results appear, you can narrow the search by adding the word “clinical.” Each report will have additional links to related research and databases. In particular, the option “Database Links” will search across technical databases that offer an abundance of information. The following is an example of the results you can obtain from the OMIM for deafness:
22
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 23 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process. 24 Adapted from http://www.ncbi.nlm.nih.gov/. Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information--all for the better understanding of molecular processes affecting human health and disease.

The Genome Database26 Established at Johns Hopkins University in Baltimore, Maryland in 1990, the Genome Database (GDB) is the official central repository for genomic mapping data resulting from the Human Genome Initiative. In the spring of 1999, the Bioinformatics Supercomputing Centre (BiSC) at the Hospital for Sick Children in Toronto, Ontario assumed the management of GDB. The Human Genome Initiative is a worldwide research effort focusing on structural analysis of human DNA to determine the location and sequence of the estimated 100,000 human genes. In support of this project, GDB stores and curates data generated by researchers worldwide who are engaged in the mapping effort of the Human Genome Project (HGP). GDB’s mission is to provide scientists with an encyclopedia of the human genome which is continually revised and updated to reflect the current state of scientific knowledge. Although GDB has historically focused on gene mapping, its focus will broaden as the Genome Project moves from mapping to sequence, and finally, to functional analysis. To access the GDB, simply go to the following hyperlink: http://www.gdb.org/. Search “All Biological Data” by “Keyword.” Type “deafness” (or synonyms) into the search box, and review the results. If more than one word is used in the search box, then separate each one with the word “and” or “or” (using “or” might be useful when using synonyms).

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on deafness can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to deafness. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to deafness. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “deafness”:

Summary: Children who are called deaf-blind are singled out educationally because impairments of sight and hearing require thoughtful and unique educational approaches in order to ensure that children with this disability have the opportunity to reach their full potential. This fact sheet provides an overview of deaf-blindness in children, defined as hearing and visual losses that cause severe communication, developmental, and educational needs, to the point that children cannot be accommodated in special education programs solely for children with deafness or children with blindness or children with multiple disabilities. After a section defining deaf-blindness, the author discusses the causes of deaf-blindness, the numbers of deafblind people (adults and children) in the United States, the challenges facing a person who is deaf-blind, communication strategies and systems for persons who are deafblind, orientation and mobility issues, individualized education, transition and rehabilitation goals, and inclusion of the deaf-blind child in the family. The author stresses that many persons who are deaf-blind have achieved a quality of life that is excellent. The fact sheet concludes with a list of suggested readings and additional resources. 1 table. 3 references.

Summary: Designed for college educators who may have deaf-blind students in their classrooms, this fact sheet offers information about the needs of this population. There is not a formula for addressing these needs because students who are deaf-blind have differing levels of hearing and vision loss. The first step is to talk with the student about the course to determine what modifications are necessary. The fact sheet describes the common types of support services and accommodations used by these students, including interpreters, notetakers, tutors, readers, and assistive listening devices (ALDs). The fact sheet then covers physical classroom accommodations, the use of handouts or ad hoc materials, the use of audiovisual materials, small group discussions and activities, oral presentations, exams and alternative testing methods, field visits and labs, teaching style, and who to contact for assistance. The fact sheet concludes that keeping an open line of communication with the student will ultimately create a positive learning and teaching atmosphere for both instructor and student. The fact sheet is one in a series of informational fact sheets from the Northeast Technical Assistance Center at the Rochester Institute of Technology (National Technical Institute for the Deaf). •

This fact sheet, from the British Royal National Institute for Deaf People (RNID), describes the British deafblind manual alphabet. Presented on cardstock, the front side shows line drawings of the alphabet; the reverse briefly describes deafblindness and the work of the RNID. The fact sheet emphasizes that communication methods used by deafblind people vary greatly depending on the amount of residual hearing and sight they have. Many people who cannot hear speech or see well enough to lipread or follow visual sign language use some form of tactile communication. The RNID is a membership charity organization that campaigns and lobbies for a better quality of life for deaf and hard of hearing people, raises awareness of deafness and hearing loss, provides direct services, and supports social, medical, and technical research.

deafened are unable to understand speech without visual aids such as speechreading, sign language, and captioning (although amplification of residual hearing may be used to assist with speechreading). Designed for college educators who may have latedeafened students in their classrooms, this fact sheet offers 16 strategies for working with students who are late-deafened. They cover introducing the student to the class, the basics of computer aided realtime translation (CART) and other communication options, the use of interpreters in the classroom, the issues covered by the Americans with Disabilities Act (ADA) and the Rehabilitation Act (Section 504), notetakers and classroom notetaking, the classroom environment (lighting and sightlines), the use of written English as a backup, regulating cross talk, providing access for out of classroom activities, strategies to help speechreaders, the use of visual aids, and the use of disability support services offered by the educational institution and by other resources (such as the Association of Late Deafened Adults). The fact sheet is one in a series of informational fact sheets from the Northeast Technical Assistance Center at the Rochester Institute of Technology (National Technical Institute for the Deaf). •

Summary: This article from Let's Talk, a newsletter of the American Speech Language Hearing Association (ASHA), focuses on Deaf culture. The author notes that many members of the Deaf community view their deafness as a unique characteristic that makes them part of a community that shares a common experience, tradition, history, and language. People who are deaf share an identity, not a disease or a disability. The article discusses the role of American Sign Language (ASL), definitions of culture and ethnicity, the impact of technology and education, accommodations and the Americans with Disabilities Act (and other legislation), and new technology that supports people who are deaf or who have hearing aids. The article includes a sidebar listing related organizations.

[email protected]. Website: clerccenter.gallaudet.edu. PRICE: $3.00 plus shipping and handling. Summary: This booklet provides information for late-deafened people, focusing on the adaptations required for previously hearing people to learn to cope with their hearing loss. The booklet first identifies two crucial aspects to defining this group of people. First, late-deafened people have an acquired hearing loss; for many years they have had normal or nearly normal hearing; and their language, identities, and cultural and educational experiences are those of hearing people. Second, late-deafened people are, in the audiological sense, deaf. That is, even with the best amplification, they cannot continue to use hearing to understand speech. The authors note that this line separating hard of hearing people from deafened people is not clear or objective. People define themselves based on their experience with communication, their comfort with particular coping strategies, and on social and support groups that match their experience and preferences. After this introductory section on definitions, the booklet covers six main areas: crisis, or the diagnostic stage, including the problem of tinnitus; communication adaptations; work, including vocational rehabilitation, and laws that protect people with disabilities; accommodations for home and recreation; getting support; and moving on. The booklet concludes with a resources section. 19 references.

Summary: This brochure describes a traveling social history exhibition about Americans who are deaf. Developed by Gallaudet University, the exhibit uses objects and images to illustrate shared experiences of family life, education, and work, as well as the divergent ways of people who are deaf and the way they see themselves, communicate, employ and adapt available technology, and determine their own futures. The exhibition places the social history of Americans who deaf within the context of better known aspects of American history. It focuses on the development of a Deaf community and identity, language as both a cohesive and a divisive force, the impact of technological change, and the struggles for self-determination. The brochure describes and shows photographs from the six sections of the exhibition: introduction and orientation to deafness, formation of a community, an oral approach to education, the war and postwar years, civil rights recognition and access, and the information age and technological choices. The principal target audience for the exhibition and its accompanying materials is hearing people who have little contact with individuals who are deaf. The brochure includes information about the curator of the exhibition (Jack R. Gannon) and who to contact to bring the exhibition for display. (AA-M).

Summary: This fact sheet presents data and information on the effects of HIV/AIDS in the deaf community. Quoting a National Coalition on Deafness estimate of 7,000 cases of HIV/AIDS and 300 deaths as of October 1993 among deaf people in the United States, the sheet offers additional statistics from various sources and indicates how little official surveillance exists to monitor rates of infection and deaths from HIV/AIDS in this population. The sheet also emphasizes that deafness is a communication disability, with the deaf community considering itself a minority group. An attached article discusses the need for increased HIV/AIDS education targeted to the deaf community. It points out that knowledge, attitudes, beliefs, and behavior related to HIV/AIDS in the deaf community lag behind the general population. The author describes risk factors among deaf persons and outlines hindrances to reaching this group, including the following: traditional informational avenues frequently fail to reach the deaf community; few educational materials are geared to meet the needs of the deaf population; and most health care providers are unable to communicate with deaf patients.

Contact: Available from AIDS Education-Services for the Deaf. Greater Los Angeles Council on Deafness (GLAD), 2222 Laverna Avenue, Los Angeles, CA 90041. Voice/TTY (213) 550-4250. PRICE: Single copy free. Summary: This fact sheet provides basic information about HIV and AIDS and its incidence in the Deaf community, an overview of the Deaf community (and the role of the Americans With Disabilities Act, or ADA, in this population), and information about deafness and AIDS education. There are only estimates of the number of people with HIV in the Deaf community. The fact sheet reminds readers that the Deaf community is different from other disabled groups by virtue of the communication process, not physical handicaps. Demographically, the Deaf community parallels other minority groups in terms of underachievement, unemployment, and underemployment. A successful AIDS education program must demonstrate an understanding of the Deaf community and its unique culture, based on a common language and maintained by a complex social strata. Formal education for many people who are deaf ends at the 12th grade. Upon completion of a secondary education, 30 percent are functionally illiterate and 60 percent read at grade level 5.3 or below. Services and educational material must be geared to meet these educational and literacy needs. The fact sheet challenges people who are deaf to acquire essential information, to educate their local Deaf communities, and to assist general AIDS agencies in providing vital services to the Deaf population.

The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to deafness. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.27
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public.

C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
