CHAPTER 4. PATENTS ON SCABIES 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.8 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 “scabies” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on scabies, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Scabies By performing a patent search focusing on scabies, 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 scabies: •
Bis-S-alkylbenzene derivatives Inventor(s): Fukaya; Chikara (Osaka, JP), Naito; Youichiro (Kyoto, JP), Sugiura; Masanori (Osaka, JP), Yamaura; Yasunari (Shiga, JP), Yokoyama; Kazumasa (Osaka, JP) Assignee(s): Green Cross Corporation (Osaka, JP) Patent Number: 4,933,329 Date filed: December 6, 1988 Abstract: Novel bis-S-alkylbenzene derivatives capable of inhibiting lipoxygenase, inparticular, 5-lipoxygenase are disclosed. It is expected that the compounds, which are hardly metabolized in vivo, are highly useful in the treatment and/or prevention of various diseases, including allergic diseases such as asthma, inflammation, myocardial infarction, nephritis, scabies and gout. Excerpt(s): This invention relates to novel bis-S-alkylbenzene derivatives which exert an inhibition effect on lipoxygenase, in particular, 5-lipoxygenase, and to a lipoxygenase inhibitor composition containing the same. 5-lipoxygenase is an enzyme involved in the in vivo synthesis of leukotrienes and 5-hydroxy-eicosatetraenoic acid (5-HETE). These compounds are believed to be involved in the outbreak of various diseases, including allergic diseases such as asthma, inflammation, myocardial infarction, nephritis, scabies and gout. Therefore, a compound capable of inhibiting 5-lipoxygenase is useful in the treatment and prevention of various diseases, including allergic diseases such as asthma, inflammation, myocardial infarction, nephritis, scabies and gout.

Composition and method for inhibiting plant disease Inventor(s): Anderson; Neil A. (St. Paul, MN), Kinkel; Linda L. (Forest Lake, MN), Liu; Daqun (St. Paul, MN), Schottel; Janet L. (Roseville, MN) Assignee(s): Regents of the University of Minnesota (Minneapolis, MN) Patent Number: 6,074,638 Date filed: May 6, 1996 Abstract: The present invention is directed to methods and compositions for biological control of plant diseases using suppressive avirulent strains of Streptomyces spp. to control disease on a vegetable or other susceptible crop. The method includes applying one or more naturally occurring, suppressive avirulent strains of Streptonmces spp. to the crop to inhibit the growth of Streptomyces scabies or other plant pathogenic organisms that cause scab, wilt, or seedling blight disease. Preferably, at least two suppressive avirulent strains of Streptomyces spp. are applied to reduce the change of resistance from occurring. The suppressive avirulent strains ame compatible and will grow in the presence of one another and, when combined with the pathogenic organism, at least one of the suppressive avirulent strains preferably substantially outgrows the pathogen. Excerpt(s): Scab disease of potatoes (Solanum tuberosum) is caused by several species of Streptomyces. The pathogen was first isolated in 1890 in the state of Connecticut and

named Oospora scabies based on its melanin production and gray spores borne in spiral chains. Thaxter, Aqric. Expt. Sta. Rept., 81:95 (1890). The organism was later renamed as Streptomyces scabies. Waksman et al., J. Bacteriol., 46:337-341 (1948). Taxonomy of the organism has changed significantly over the years as different isolates of Streptomyces causing scab disease on potatoes have been given different names. S. scabies was eventually reevaluated and the original description of the organism was changed to include smooth spores and use of all ISP sugars. Elesaway et al., ACTA Microbiol. Acad. Sci. Hung., 26:311-20 (1979). At present, the taxonomy of S. scabies is based on morphological and biochemical characteristics. The confusion over Streptomyces taxonomy may be attributed to the organism's ability to produce sectors readily in culture and extreme sensitivity to physical variations of cultural conditions. Erikson, J. Gen Microbiol., 13:136-148 (1955). A number of different strains causing potato scab in the eastern United States and Canada were isolated, determined to be the same species, and grouped as Streptomyces scabies. Lambert et al., Intl. J. Systematic Bact. 39:387-392 (1989). Data indicated that S. scabies formed a homogeneous group characterized by smooth gray spores borne in spiral chains, melanin production, and utilization of all ISP sugars. It was thus proposed to revive the name S. scabies for the group of organisms which caused common scab of potato. At present, the species S. scabies is not listed in Bergey's Manual of Determinative Bacteriology (8th edition), Buchanan et al., Williams and Wilkins Co., Baltimore, Md. (1974).

Control of parasitic mites with alkyl amines Inventor(s): Fisher; William F. (Kerrville, TX), Robbins; William E. (Silver Springs, MD), Thompson; Malcolm J. (Baltimore, MD), Wright; Fred C. (Kerrville, TX) Assignee(s): The United States of America as represented by the Secretary of (Washington, DC) Patent Number: 4,230,726 Date filed: June 29, 1979 Abstract: Certain secondary and tertiary straight and branched chain amines and amides are found to be highly effective for controlling scabies mites and other parasitic mites. Excerpt(s): This invention relates to the control of scabies mites and other parasitic mites and more specifically to the control of these parasites with certain straight and branched-chain amines and amides. A particular shortcoming in the control of scabies mites in livestock is the fact that at present there are only four chemicals registered with the Environmental Protection Agency for use in the United States as dips on cattle and sheep. Although the four chemicals are effective in the control of scabies, their use presents certain disadvantages. Three of the chemicals, toxaphene, coumaphos, and phosmet, cannot be used on lactating dairy cattle and beef cattle treated with phosmet and toxaphene must be held 21 and 28 days, respectively, before slaughter to avoid pesticide residue problems. In fact, toxaphene, one of the most widely used agricultural insecticides in the world, has been found by the National Cancer Institute to cause liver cancer in male and female mice (Chemical and Engineering News, Volume 57, No. 12, March 19, 1979, page 20). The fourth chemical, lime-sulfur, which is used on lactating dairy cattle must be heated to 95.degree. to 105.degree. F. to be effective. Some of the compounds of the present invention are also useful in the control of nematodes and other helminths, U.S. Pat. No. 4,036,987 and No. 4,073,939.

(Kerrville, TX) Assignee(s): The United States of America as represented by the Secretary of (Washington, DC) Patent Number: 4,464,390 Date filed: November 23, 1982 Abstract: Certain aliphatic carbamates and thiocarbamates are useful in controlling scabies mites and other parasitic mites. Excerpt(s): This invention relates to the control of scabies mites and other parasitic mites and more specifically to the control of these parasites with certain aliphatic carbamates and thiocarbamates. A particular shortcoming in the control of scabies mites in livestock is the fact that at present there are only four chemicals registered with the Environmental Protection Agency for use in the United States as dips on cattle and sheep and approved by the Animal and Plant Health Inspection Service, U.S. Department of Agriculture, for quarantine purposes. Although the four chemicals are effective in the control of scabies, their use presents certain disadvantages. Three of the chemicals, toxaphene, coumaphos, and phosmet, cannot be used on lactating dairy cattle, and beef cattle treated with phosmet and toxaphene must be held 21 and 28 days, respectively, before slaughter to avoid pesticide residue problems.

Ectoparasite detection method Inventor(s): Spiesel; Sydney Z. (77 Everit St., New Haven, CT 06511) Assignee(s): none reported Patent Number: 5,997,847 Date filed: January 7, 1998 Abstract: A method of detecting the infestation of a host by arthropod ectoparasites uses a fluorescent dye which stains the ectoparasites and/or their eggs but not the adjacent skin or hair to which they are attached. The dye can be incorporated into a shampoo or a rinsing solution and is applied to the scalp or other region of the host. After a suitable period of time has elapsed, the dye-containing solution or shampoo is rinsed off and the hair and adjacent area of the host examined under ultraviolet or near-ultraviolet light. Such illumination will cause the stained ectoparasites and/or eggs to glow and, thus, become easily detectable for diagnosis and subsequent removal. The method may be applied to detect scabies (i.e. skin-burrowing mites), head lice, body and pubic lice and to any other arthropod ectoparasites and their eggs containing a substantial percentage of chitin.

Excerpt(s): The present invention generally relates to the field of ectoparasite detection. More particularly, the invention relates to methods and apparatus for the detection of arthropod ectoparasites and their eggs which have infested live hosts such as humans or other animals. Accordingly, the general objects of the present invention are to provide novel and improved methods and apparatus of such character. Arthropod ectoparasite infestation is an enormously persistent and troubling condition today even in industrialized nations. For example, pediculosis capitis or head lice infestation presently afflicts an estimated 12 million patients or hosts in the United States alone. Most of these hosts are school children. These arthropod ectoparasites are easily spread from child to child and are hard to eliminate once the host child has been infested. The lice themselves, which generally remain at or near scalp level, are small and difficult to find. Naturally, once infestation has begun in a host, the condition persists and is exacerbated by the reproductive cycle of the lice. Thus, the lice produce eggs, or nits, which are tenaciously affixed near the bottom of the hair shafts by a cement produced by female lice. Given this, it has long been recognized that the key to pediculosis diagnosis and treatment lies in the detection and removal of nits. In early days, control of this parasite was accomplished by a variety of wholly manual treatments. For example, lice detection and removal has long been effected by laboriously searching the scalp of an infested host and hand-removing individual louse eggs, or nits, attached to the hairs of the host. Painful and slow combing with a fine-tooth comb has also been commonly used to remove nits. This method is generally considered to be a slightly faster and more effective variant of the hand-removal method. Other methods of nit and/or louse removal include shaving the scalp or soaking the hair and scalp with dangerous materials such as kerosene. More recently, efforts have concentrated on developing chemical pediculicides to treat lice infestation. One significant drawback of such pediculicides is that evolutionary selective pressures inevitably give rise to strains of head lice which are resistant to the pediculicides. Thus, newly developed pediculicides rapidly lose effectiveness. Accordingly, removal of nits by hand or with a fine-tooth comb remains the most effective method of removing head lice. Since nits are generally less than a millimeter in diameter, they are quite hard to detect, especially in children with thick, fine hair. Thus, it is still common for a thorough delousing of the scalp using a fine-tooth comb to require over one and one half hours. Further, this combing process often needs to be repeated daily because it is so easy to overlook nits. Web site: http://www.delphion.com/details?pn=US05997847__ •
Treatment for scabies Inventor(s): Berger; Richard S. (Plainsboro, NJ) Assignee(s): Johnson & Johnson (New Brunswick, NJ) Patent Number: 4,150,141 Date filed: June 28, 1977 Abstract: Levamisole, a known anthelmintic, is effective in treating scabies when given systemically at dosage levels of about 2.5 mg/kg/day, two consecutive days per week until the patient is disease free. From one to four weeks of such treatment has been found to be generally adequate for cure, without causing significant side effects. Topical treatment with levamisole in a suitable vehicle may be used as an alternative to systemic treatment. Excerpt(s): The present invention relates to a treatment for scabies in humans and other mammals. More particularly, it relates to the use of an anthelmintic, levamisole, as well

as its racemate, tetramisole, and the pharmaceutically acceptable acid addition salts thereof, to treat this condition. The mite, Sarcoptes scabiei, is the cause of scabies. It burrows under the upper layer of the skin, producing an inflammatory response and intense itching. The cutaneous diagnostic signs include multiple papules, minute vesicles and occasional linear tracts. The transmission of scabies has always been associated with close personal contact, and no age or socioeconomic group escapes the disease. The presence of scabies as a disease affecting humans occurs in thirty year cycles. Web site: http://www.delphion.com/details?pn=US04150141__ •

(Wirral, GB2) Assignee(s): Lever Brothers Company (New York, NY) Patent Number: 4,824,865 Date filed: January 12, 1987 Abstract: The use of a curative agent chosen from 2-hydroxyoctanoic acid, 2ketooctanoic acid and certain esters thereof in the preparation of a pharmaceutical composition for the treatment of skin disorders such as Ichthyosiform dermatoses, Conradi's syndrome, Localized hyperkeratotic conditions, Dandruff, Callous forming disorders, Psoriasis, Eczema, Xerosis, Warts, Tinea pedis, Pityriasis, Lichen planus and simplex chronicus, Darier's disease, Pruritus, Seborrhoeic conditions and Scabies. Excerpt(s): The invention relates to the treatment of certain skin disorders, and more particularly to the use of a curative agent chosen from a specific hydroxy acid, keto acid and derivatives thereof in the preparation of pharmaceutical compositions for the treatment of certain specified skin disorders. The conventional treatment of skin disorders such as ichthyotic dermatoses, hyperkeratosis and related conditions has included topical application to the affected area of skin of ointments, creams, lotions or powders containing one or more of a wide variety of active ingredients such as organic and inorganic acids, steroids, fungicides, antibiotics and anti-inflammatory substances. Usually, remission of the disorder is slow and frequently incomplete. Complete remission and cure of some skin conditions can usually only be obtained by the use of potent drugs, such as steroids, having often severe contra indications which limit their widespread use without medical supervision. Also, the topical application of caustic chemicals in the treatment of localised conditions, such as warts, is often accompanied by pain or discomfort which also limits their use.

Methods and compositions for treating ectoparasite infestation Inventor(s): Campbell, William R.; (Jamestown, NC), Palma, Kathleen G.; (McLeansville, NC), Paulsen, Neil E.; (Davidson, NC) Correspondence: Foley & Lardner; P.O. Box 80278; San Diego; CA; 92138-0278; US Patent Application Number: 20030202997 Date filed: April 29, 2002 Abstract: Compositions and methods for killing ectoparasites on a subject. Compositions containing a fatty acid ester, e.g., isopropyl myristate, effective for killing ectoparasites is described. Also described are compositions containing a fatty acid ester and a siloxane (e.g. decacyclomethicone). The compositions can also contain a mectin and/or a mycin, and S-methoprene. The compositions are useful against a variety of ectoparasites that afflict humans, animals, and plants, e.g., head lice, fleas, body lice, crab lice, scabies, ticks, and plant parasites. Excerpt(s): The present invention relates generally to methods and compositions for killing ectoparasites. Head lice infestation is a persistent problem with as many as 6-12 million people worldwide affected each year. The problem is particularly prevalent in children with preschool and elementary-age children aged 3-10 and their families becoming infested most often. Head lice infestation is produced by the common head louse Pediculus humanus capitis, and typically causes itching of the scalp. As the lice feed on human blood, they may cause lesions to develop on the scalp, swollen glands on the neck or under arms, or other symptoms. Head lice infestation causes serious problems due to the negative social implications of the infestation. Body lice are also bothersome to humans and carry the additional hazard of being the vectors of certain diseases, such as exanthematic or epidemic typhus and recurrent fever. Various compositions are available for treating these infestations, which generally take a topical approach to treatment. Most of these treatments involve the use of insecticides that are harsh agents, thus raising toxicity concerns. The lice can also become resistant to the insecticides used and therefore the compositions can lose their effectiveness over time. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Style-n-sleeve Inventor(s): Carraway, Eric Unedsa; (Raleigh, NC) Correspondence: Eric U. Carraway; 156 E. Chatham Street; Cary; NC; 27611; US Patent Application Number: 20010039673 Date filed: January 19, 2001 Abstract: The Style-N-Sleeve is designed to alleviate the saturation of clothing by potentially harmful pathogens such as lice, ringworms, scabies, hair particles, dandruff, etc. It is also designed to keep these pathogens out of direct contact with the skin of the stylists. In doing so, the sleeve is constructed of a light thin breathable material that is either worn over clothing or the bare arm. The texture of this material is semi-water repellant and very smooth allowing hair particles and these pathogens to easily slide off. Without the clothing being saturated with these pathogens, the invention assists in the improvement of the overall hygiene of the stylists and the sanitation of the profession. Excerpt(s): The present invention relates to a protective garment, even more specifically, the present invention relates to a sleeve for preventing contamination of the skin and
74
Scabies
clothing of barbers and cosmetologist from potentially harmful pathogenic particles that may come from the hair and/or scalp of individual clients. Although the nature of this contamination originates in the salon or barber shop, it is not limited to the place of employment. Often times, stylists transport these parasitic pathogens as they perform their normal duties throughout the working day. These pathogens are transported to beauty supply stores, restaurants and even to the homes of individual stylists. Once these pathogens are transported to the home, the clothing and living areas may become infected. Examples of a number of these pathogens range from: ringworms; lice; scabies, dandruff, hair particles, and blood to name a few. There is a need for this invention in terms of sanitation for the working environment of barbers and stylists. This endeavor is a highly effective device designed to eliminate the contamination of the skin and clothing of stylists, as well as their food, homes and families. The clients are protected by a protective cape and neck strips, while barbers and stylists are protected by smocks, aprons and vests. However, these protective garments currently used by barbers and stylists offer minimal protection as they only cover the main body of the stylist. Vest and aprons are sleeveless, while smocks, male/female are typically short-sleeved, three quarter-sleeved respectively, leaving the portion below the elbow exposed, therefore venerable to direct contact with these pathogens.

Vaccines for the protection of cattle from psoroptic scabies Inventor(s): Fisher, William F.; (Kerrville, TX), Kunz, Sidney E.; (Kerrville, TX), Pruett, John H.; (Kerrville, TX), Temeyer, Kevin B.; (Boerne, TX) Correspondence: Usda-ars-office OF Technology Transfer; National Ctr For Agricultural Utilization Research; 1815 N. University Street; Peoria; IL; 61604; US Patent Application Number: 20020136734 Date filed: May 18, 2001 Abstract: A novel antigenic protein which is effective for stimulating antibody production in animals against the sheep scab mite, Psoroptes ovis is disclosed. In cattle, administration of the protein provides protection from infestation by P. ovis by eliciting an immediate-type hypersensitivity response and/or immunizing the animal against P. ovis. The protein is also effective for producing and/or binding antibodies to P. ovis, and may be used as an immunodiagnostic reagent. Excerpt(s): The invention relates to a novel protein from the sheep scab mite, Psoroptes ovis, which may be used for eliciting host-protective grooming behavior and/or immune response in cattle. Psoroptes ovis (Hering) (Acarina: Psoroptidae), the globally distributed sheep scab mite, is an economically important parasite of domestic cattle and sheep, and a serious threat to wild populations of bighorn sheep (Boyce & Brown, 1991, J. Parasitol. 77:675-679). Mite infestation of susceptible cattle can result in the development of scabies lesions. The lesion is consistent with allergic dermatitis (Stromberg & Fisher, 1986, Am. J. Vet. Res., 47:1551-1560) characterized histologically by superficial perivascular dermatitis, marked edema in the superficial dermis, numerous eosinophils, and mast cells (Stromberg & Guillot, 1989, Am. J. Vet. Res., 50: 594-601). The dermatitis can become extensive and lead to the death of cattle in poor condition, and under extremes of environmental stress. It has been suggested that death may occur as a result of the high demand, and consumption of neutrophils at the lesion site, leaving other tissues such as the lungs susceptible to secondary bacterial infection (Stromberg & Guillot, 1987, Vet. Pathol., 24: 365-370). Stanchioned cattle repeatedly infested with P.
Patents 75
ovis appear to develop some level of resistance, defined by a slower rate of lesion and mite population growth (Stromberg & Fisher, 1986, ibid). Guillot & Stromberg (1987, Vet. Parasitol., 10:73-78) suggested that the slow progression of lesion and mite population expansion on stanchioned resistant cattle could be attributed to a lowered ovipositional rate of the female mites, by some unexplained mechanism. Losson et al. (1988, Res. Vet. Sci., 44:197-201) reexposed unstanchioned cattle to P. ovis and the cattle exhibited signs of immediate hypersensitivity including pruritus, scratching, and exudation. Scabies lesions developed on these cattle but healed rapidly and none of the cows developed clinical scabies. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

PRICE: $395.00 plus shipping and handling. ISBN: 0070219435. Summary: This chapter provides health professionals with information on the etiology, clinical manifestations, diagnosis, and treatment of scabies and pediculosis. Scabies, which occurs in both sexes and in any age group, is transmitted by skin to skin contact. Itching, a symptom of classic scabies, is usually nocturnal. Diagnosis is made by microscopic identification of the mites, eggs, or fecal pellet. Treatment involves application of scabicides such as permethrin 5 percent cream, lindane, sulfur, crotamiton cream, and ivermectin. Special forms of scabies include scabies in patients with good hygiene, scabies incognito, nodular scabies, scabies in infants and young children, scabies in the elderly, crusted scabies, scabies in patients with human immunodeficiency syndrome and acquired immunodeficiency syndrome, scabies of the scalp, and bullous scabies. Pediculosis is an infestation by the head louse, the body or clothing louse, or the pubic or crab louse. Pruritus is the most common symptom in any type of pediculosis. Head lice infestations, which are usually confined to the scalp, are common in children. The main symptom is intense itching. Diagnosis is confirmed by plucking the hairs and studying them microscopically to differentiate the nits from seborrheic scales, hair casts, and artifacts of the hair that may be brushed off easily. Agents used to treat head lice include a 1 percent synthetic pyrethroid permethrin cream rinse, synergized pyrethrins, and lindane shampoo. Pubic lice are transmitted sexually. The pubis is the most commonly affected site. Diagnosis is usually made by identifying the more numerous nits cemented on the pubic or perianal hair. Agents used to treat pubic lice include synergized pyrethrins and lindane shampoo. Body lice are mainly transmitted by contaminated clothing or bedding. The characteristic eruption consists of numerous vertical excoriations caused by intense itching. Therapy for body lice consists mainly of proper hygiene, bathing, use of clean clothing and bedding, and proper nutrition. 10 figures, 2 tables, and 22 references.

CHAPTER 8. 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 scabies. 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 scabies. 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

Coffee Break: Tutorials for Biologists19 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.20 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.21 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/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
19 Adapted 20
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
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. 21 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.
99
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 scabies 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 scabies. 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 scabies. 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 “scabies”:

You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on scabies. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The following was recently posted in this archive: •
Scabies Source: Schaumberg, IL: American Academy of Dermatology. 2001. 8 p. Contact: Available from American Academy of Dermatology. 930 N. Meacham Road, P.O. Box 4014, Schaumberg, IL 60168. (888)462-DERM ext.22. Website: www.aad.org. PRICE: Single copy free. Summary: This brochure discusses scabies, a skin condition caused by mites burrowing into the skin that causes intense itching. This condition can affect individuals of all races and ages regardless of personal hygiene. Scabies is most common in children, mothers of young children, and elderly individuals in nursing homes. It is spread by being in close contact with someone who has been infected. The mite that causes scabies has eight legs and burrows in to the warm parts of the skin. Bacterial infections may occur as a result of scratching, which is worse at night. Crusted scabies is a form of the disease that occurs mostly among the elderly or in some AIDS patients. The crusts hide thousands of mites and their eggs. Scabies is easily treated with prescription creams. Antihistamines can be prescribed to help relieve itching. Oral medications may be used for difficult or resistant cases. 5 figures.

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 scabies. 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. PEDBASE Similar to NORD, PEDBASE covers relatively rare disorders, limited mainly to pediatric conditions. PEDBASE was designed by Dr. Alan Gandy. To access the database, which is more oriented to researchers than patients, you can view the current list of health topics covered at the following Web site: http://www.icondata.com/health/pedbase/pedlynx.htm.

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to scabies. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with scabies. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about scabies. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “scabies” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. 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.22
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. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

[NIH] Cloning: The production of a number of genetically identical individuals; in genetic engineering, a process for the efficient replication of a great number of identical DNA molecules. [NIH] Coal: A natural fuel formed by partial decomposition of vegetable matter under certain environmental conditions. [NIH] Cofactor: A substance, microorganism or environmental factor that activates or enhances the action of another entity such as a disease-causing agent. [NIH] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. 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
118 Scabies
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. [EU] Complementary and alternative medicine: CAM. Forms of treatment that are used in addition to (complementary) or instead of (alternative) standard treatments. These practices are not considered standard medical approaches. CAM includes dietary supplements, megadose vitamins, herbal preparations, special teas, massage therapy, magnet therapy, spiritual healing, and meditation.
