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 keloids 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 keloids, 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 keloids, 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 keloids. 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 keloids, 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 keloids. The Editors

CHAPTER 1. STUDIES ON KELOIDS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on keloids.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and keloids, 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 “keloids” (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: •

Contact: Available from American Dental Association. ADA Publishing Co, Inc., 211 East Chicago Avenue, Chicago, IL 60611. Summary: Keloids are thick, disfiguring scars that usually result from trauma to the skin induced by injuries such as burns or piercing, acne, or surgery within subpopulations of dark skinned people. This article describes keloids, wound healing, and present research on the skin as a frontier of defense for the body. Topics include the incidence and prevalence of keloids, how molecular defects contribute to keloid scarring, growth factors and keloids, and the clinical management of keloids. The clinical management of keloids in dentistry and medicine includes dressings and pressure devices,

Keloids and Hypertrophic Scars: Review and Treatment Strategies Source: Seminars in Cutaneous Medicine and Surgery. 18(2): 159-171. June 1999. Summary: This journal article provides health professionals with information on the clinical, histopathological, and biochemical features of keloids and hypertrophic scars and on methods of treating them. Keloids and hypertrophic scars represent exuberant forms of scar formation that frequently are pruritic and painful, and occasionally form strictures. They may result in significant cosmetic disfigurement. A keloid is characterized histologically by the haphazard deposition of collagen fibers within the dermis, surrounded by a mucinous extracellular matrix with few macrophages and an abundance of eosinophils, mast cells, plasma cells, and lymphocytes. Histologically, hypertrophic scars also show increased collagen bundles. Biochemical features of keloids and hypertrophic scars include increased collagen synthesis, increased levels of certain immunoglobulins, and alterations in growth factor levels. Recent years have seen a better understanding of the molecular and biological mechanisms of keloidal scar formation, allowing for the development of more specific therapeutic options. These include surgical excision, radiotherapy, mechanical pressure, topical silicone gel sheeting, laser surgery, corticosteroid injections, cryosurgery, interferon therapy, and various pharmacological therapies. Despite these developments, keloids and hypertrophic scars remain difficult to manage. Many clinicians use several approaches in combination or sequentially. Development of a reliable animal model for keloid and hypertrophic scar formation, further molecular analysis of these lesions, and comparative analyses of fetal wound healing will significantly aid in the pursuit of better treatments. 1 figure and 141 references.

Federally Funded Research on Keloids The U.S. Government supports a variety of research studies relating to keloids. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to keloids. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore keloids. The following is typical of the type of information found when searching the CRISP database for keloids: 2

Principal Investigator & Institution: Longaker, Michael T.; Professor of Surgery; Surgery; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2006 Summary: (provided by applicant) The long-term goal of this proposal is gain a better understanding of the biomolecular mechanisms underlying keloid pathogenesis. Keloids are the result of pathologic over-healing and represent a worldwide biomedical burden with approximately two billion people at risk. Keloids are not only aesthetically unattractive, but can result in functional impairments and physical deformity with many attendant fiscal, social, and psychological sequelae. In general, we propose to study the molecular biology of keloid pathogenesis using a four-pronged approach. First, we intend to employ a novel co-culture system to investigate the interactions of two important cell-types (keratinocytes and fibroblasts) believed to be critical to the formation of keloids in vivo. We will utilize mix and match combinations of normal skin-derived human keratinocytes (NHKs) or keloid-derived human keratinocytes (KHKs) with normal skin-derived human fibroblasts (NHFs) or keloid-derived human fibroblasts (KHFs). This step will allow us to isolate and focus on these four cell types and their specific interactions. Second, because keloids have a propensity to develop in areas of the body where skin stretch and movement are prevalent, we will examine the effect of equibiaxial strain on these four cell types and determine its effect on gene expression and protein synthesis. Third, we intend to make use of the strong environment for microarray analysis here at Stanford University to study the gene expression of NHKs, KHKs, NHFs, and KHFs. This powerful technology, will allow us to analyze differential gene expression on a genome-wide basis. We can, therefore, use microarray analysis to characterize the large-scale gene expression phenotypes of these four cell types in isolation as well as in coculture. Finally, we intend to use an innovative grafting technique to place cutaneous keratinocyte/acellular dermal grafts onto nude mice. We will pre-seed these grafts with either NHKs or KHKs and eventually NHFs and KHFs in mix and match combinations. In this way, we hope to create an in vivo analog to our in vitro coculture model. The central hypothesis to be tested in this proposal is that KHKs interact with KHFs in promoting keloid pathogenesis Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

This application will

focus on the role of altered expression of plasminogen activator inhibitor-1 (PAI-1) in collagen over-production by keloidfibroblasts. Proteolytic degradation of the provisional fibrin matrix and remodeling of the newly formed collagen-containing scar tissues are essential features in injury repair. Keloids, resulting from improper wound healing, are the extreme form of skin fibrosis with unknown etiology. Using a 3dimensional fibrin gel culture system, we discovered that keloid fibroblasts are defective in fibrin degradation due to PAl-1 over-expression. In the previous granting period, we established, both in vitro and in vivo, that PAI-1 overexpression is phenotypic of keloid fibroblasts and is causal in the elevated collagen accumulation. Reducing PAI-1 activity also abolishes the elevated collagen accumulation in keloid fibroblasts (Tuan et al., Am J Pathol 2003). In addition, we demonstrated that, in vivo, PAI-1 increases as fetal mouse skin wounds transition from scarless (El5) to scarforming (E18 and after) repair, and aprotinin, a uPA/plasmin inhibitor, causes scar formation in E15 fetal skin wounds (Huang et al., WRR 2002). PAI-1 is the major inhibitor of the plasminogen activator (PA)/plasmin system. This system is central to fibrin degradation, cell adhesion and migration, and metalloproteinase (MMP) activation, which is essential in collagen turnover. Thus, we hypothesize that "PAl-1 contributes to elevated collagen accumulation in keloid fibroblasts by inhibiting MMP activation and or by modulating uPA-mediated cell adhesion". PAI-1 is a down stream target of TGF-beta, and keloid fibroblasts exhibit TGF-beta-mediated differences in matrix contraction and collagen synthesis. Thus, we also hypothesize that "an altered TGF-beta signaling pathway and or utilization of PAI-1 promoter response elements are responsible for increased PAI-1 expression in keloidfibroblasts" The established evidence and the unique experimental models will allow us to test these hypotheses through the following specific aims: Aim I: To investigate the role of PAI-1 increase in MMP- and cell adhesion-mediated collagen accumulation in keloid fibroblasts. Aim II: To determine the biological mechanism of PAI-1 increase resulting from altered TGFbeta signaling events and/or difference in PAI-1 promoter utilization in keloid fibroblasts.

Project Title: FIBROBLAST CD 90 EXPRESSION IN FIBROGENIC SKIN DISORDERS Principal Investigator & Institution: Hagood, James S.; Associate Professor; Pediatrics; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2002; Project Start 01-AUG-2000; Project End 31-JUL-2003 Summary: (Taken from the application): Following skin injury, fibroblasts enter the wound, proliferate, and produce and reorganize connective tissue, restoring strength and function to the wounded site. If this process is disordered or excessive, fibrotic scarring results. Keloids and hypertrophic scars are painful and disfiguring examples. In scleroderma, fibrotic scarring forms in skin and other organs without prior injury, causing deformity, debilitation, and in some cases, death. The long-term goal to which the proposed research is directed is to understand how excessive fibrosis occurs and to develop new ways to prevent or treat it. Fibroblasts isolated from fibrotic tissues have many distinctive features, but it remains unclear how they acquire these features and whether all fibroblasts are equally involved. Prior investigations have defined heterogeneous features of normal rodent fibroblast subsets based on whether they express the cell surface marker Thy-l. However, to date Thy-l expression in fibrotic states has not been explored, nor has there been correlation of expression of CD90, the human Thy-l equivalent, with human 'fibroblast heterogeneity. We hypothesize that

absence of Thy-1CD90 on the fibroblast surface correlates with a phenotype predisposed to participate in fibrotic responses, and that examination of fibrogenic lesions in human skin will demonstrate a higher proportion of fibroblasts lacking CD90 compared to normal skin. Thus, the aims of the project are: 1) to characterize fibroblast CD90 expression in hypertrophic scars. keloids, and scleroderma-affected skin in comparison to normal skin and normal scars, by immunostaining of tissue sections and cultured fibroblasts; 2) to characterize expression of type I collagen and connective tissue growth factor in sorted CD90 (-/+) and Thy-l (-/+) fibroblast populations: and to define the profile of differential gene expression in CD90 and Thv-l(-/+) subpopulations. Establishing the role of fibroblast Thy-1/CD90 expression in human fibrogenic skin diseases is likely to unlock mechanisms of fibroblast activation and lead to more effective treatments for fibrotic disorders in skin and other tissues.

Project Title: HYPOXIA REGULATION OF VEGF/VEGF RECEPTORS IN KELOIDS Principal Investigator & Institution: Le, Anh D.; Oral and Maxillofacial Surgery; Charles R. Drew University of Med & Sci 1621 E 120Th St Los Angeles, Ca 90059 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-AUG-2005 Summary: We postulate that an imbalance in vascular homeostasis could contribute to a hypervascular state at the inflammatory border (erythematous) or a hypovascular state at the stable portion (classical keloid) of the keloid lesion, as observed clinically and histologically. The hypovascular or hypoxic state present at the stable portion is the key factor for induction and prolongation of the hypervascular and hyperpermeable features. These features, characteristic of the granulation tissue phenotype, are responsible for the maintenance of an enriched milieu of cytokines and growth factors for continuing support of dermal growth. Our study will focus on vascular endothelial growth factor (VEGF) as a major regulator of keloid vascular homeostasis. The proposed keloid study model will be established on three clinically distinct lesional sites--inflammatory (erythematous), stable (classical keloid) and central portion (regressing scar)--which represent the pathologic course of keloid formation. The role of transcription factor, hypoxia- inducible factor, HIF-1, and hypoxia-responsive element, HRE, in the regulation of hypoxic-induced VEGF expression at the stable portion of the keloid will be determined in correlation with the granulation tissue phenotype observed at the inflammatory border. The interaction between angiogenic stimuli, VEGF, HIF-1, and the extracellular proteases, urokinase plasminogen activator, uPA, and its inhibitor, PAI-1, will be investigated in our unique three-distinct-sites approach to elucidate the molecular basis of differential vascular formation in keloids. We hypothesize that a dysregulation in wound angiogenesis contributes to a differential distribution of vascular network, hypovascular or hypoxic at the stable portion of the lesion versus hypervascular and hyperpermeable at the inflammatory border, establishing the benign growth of the keloid phenotype. Our hypothesis will be tested using the following specific aims: 1) To confirm that VEGF/VEGF receptor(s) and uPA/PAI-1 are differentially expressed in human microvascular endothelium of keloids at the three distinct sites compared to adjacent clinically normal skin; 2) To study the effect of hypoxic stress on the expression of uPA/PAI-1 and VEGF/VEGF receptor(s), receptor affinity, biological functions including phosphorylation and in vitro angiogenic activity; 3) To study the effect of VEGF on the expression of uPA /PAI-1 and their role in keloid vascular homeostasis; and 4) To delineate the role of transcription factor, HIF-1, and HRE on hypoxia-induced VEGF expression.

Project Title: MINORITY PREDOCTORAL FELLOWSHIP PROGRAM Principal Investigator & Institution: Handy, Jeffrey A.; Microbiology; Meharry Medical College 1005-D B Todd Blvd Nashville, Tn 37208 Timing: Fiscal Year 2002; Project Start 01-JAN-2002 Summary: The long term goal of this laboratory is to elucidate the mechanisms underlying the formation of keloids, which are benign tumors that develop during an abnormal wound healing program. Our laboratory has reported an abnormal pattern of responses of keloid fibroblasts in vitro that may help to elucidate the underlying mechanism of abnormal growth and matrix metabolism of keloids, in vivo. In cultures derived from keloid and normal dermal fibroblasts, TGFbeta partially reverses the stimulation of DNA synthesis by EGF, PDGF, and SmC in normal, but not keloid cells. It has been reported that, in mink epithelial cells, growth inhibition by TGFbeta is linked to decreased phosphorylation of the retinoblastoma protein during Gl progression and induction of transcription of genes encoding certain inhibitors of cyclin dependent kinases. Therefore, the specific aims of the studies described herein are to 1) determine if the differential effects of TGFbeta on the response of keloid and normal fibroblasts to EGF are accompanied by differential phosphorylation of the retinoblastoma (Rb) protein, and 2) determine if these effects are accompanied by differential expression of the cyclin dependent kinase inhibitors p15 and p21. Confluent cultures from both keloid and normal fibroblasts in 1 percent serum will be exposed to either TGFbeta alone, EGF in the presence or absence of TGFbeta, or neither growth factor. Cells from each condition described will be harvested at various times for immunoblotting with antibodies against either Rb, p15 or p21. Intensity of the bands will estimate protein levels and relative electrophoretic mobility will vary with the phosphorylation status of Rb. The outcomes of these studies will contribute to an understanding of the pathology underlying the formation of keloids, the regulatory events governing cell cycle progression, and the effects of perturbation of those events on biological systems.

Project Title: MOLECULAR MECHANISMS FOR KELOID FORMATION Principal Investigator & Institution: Reichenberger, Ernst J.; Biostructure and Function; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2002; Project Start 10-SEP-1999; Project End 31-AUG-2004 Summary: The long-term goal of this study is to understand the molecular mechanisms of neoformation of dermal tissue in fibrotic diseases. To achieve this goal we began to study hereditary keloid formation. Keloids are benign tumors of the skin or cornea caused by clonal overactivity of fibroblasts during abnormal wound repair. The relatively large number of familial cases of keloid formation makes it possible to propose a genetic approach for the identification of a gene responsible for increased cell proliferation and extracellular matrix expression. We performed linkage analysis of one large family afflicted with an autosomal dominant form of hereditary keloid formation to identify the chromosomal locus of the disease gene by using polymorphic microsatellite markers covering the entire genome. We have identified a possible disease gene locus and are now in the process of establishing a high resolution map of the keloid locus by including other pedigrees that show locus homogeneity. Ideally, the interval will be restricted to less than 1-2 cM. The keloid gene will be identified by candidate gene cloning, positional candidate gene cloning, or positional cloning. We will construct a physical map of the keloid locus using YAC and cosmid clones covering this interval. Once the disease gene has been identified by mutation analysis and by co-

segregation with the affected phenotype, studies are planned to characterize the protein product and its interactions with other genes or gene products. Depending on the nature of the keloid gene, we will plan in vitro studies of fibroblast and organ cultures as well as a mouse model that expresses the mutated gene by homologous recombination (knock-in). These studies should enable us to perform further studies on down-stream events, which are involved in the fibrosis of keloid scars. Identifying and characterizing the keloid gene product, and identifying other proteins or genes with which it interacts, will help us understand abnormal fibroblast regulation. We suggest that keloids are an excellent model for studying regulation of fibroblast activation and extracellular matrix expression during wound healing and fibrosis.

Project Title: PILOT: KELOIDS Principal Investigator & Institution: Williams, Scott Matthew.; Associate Professor; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2003; Project Start 01-MAY-2003; Project End 30-APR-2004 Summary: Specific Aims: Keloids are benign collagenous tumors that develop during an exaggerated wound healing response of the skin. Even though keloids occur in less than 1% of the overall US population, they occur in 4.5% to 16% of African Americans. They have a 45-100% recurrence rate after surgical excision. While keloids are clearly familial and can have autosomal dominant or autosomal recessive modes of inheritance in some families, the gene(s) responsible have not been identified. We propose to map the gene(s) that cause keloids in African-American families by the following specific aims: 1. Ascertain and recruit individuals from African-American families with multiple affected individuals. Blood samples will be collected from as many family members as possible, both keloid formers and non-formers. DNA will be isolated from these samples for genetic analyses. 2. Test microsatellite markers for linkage to keloids. Initial analyses will focus on chromosome 14q22-23, where we have recently identified markers that appear to co-segregate with keloids in one African-American kindred.

Project Title: SELECTINS AND FETAL WOUND HEALING Principal Investigator & Institution: Olutoye, Oluyinka O.; Surgery; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2004; Project Start 01-FEB-2004; Project End 31-JAN-2008 Summary: (provided by applicant): The overall objective of this project is to gain an in depth understanding into the role of selectins in the modulation of the inflammatory response following wounding in the adult and fetus. Fetal dermal wound healing is characterized by a scant inflammatory response and minimal fibrosis. Although fetal inflammatory cells are generally considered immature, an acute inflammatory response (with fibrosis) can be evoked at the site of fetal wounds by the application of diverse stimuli. Selectins are cell surface lectin molecules expressed on both leukocytes and endothelial cells that interact with their respective carbohydrate ligands to facilitate the early events of leukocyte recruitment, and thereby, contribute significantly to the inflammatory process. The contributions of these adhesion molecules to wound closure, repair and scar formation are poorly understood. This study is therefore proposed to evaluate the role of selectins in wound healing. The application will be centered on the hypothesis that the minimal inflammation noted in fetal dermal wounds is a consequence of alterations in expression of P- and E-selectin on fetal platelets and

endothelial cells. To test this hypothesis, the relative expression of selectins on adult and fetal platelets and endothelial cells will be determined. Mice with targeted deletions of individual or combinations of selectins will be studied to determine the consequences of selectin absence on wound healing. Using the murine syngeneic fetal skin transplantation model and creating mice chimeric for selectins, the specific contributions of platelet or endothelial selectins in the inflammatory response will be elucidated. Understanding the mechanism of scarless fetal wound healing will provide alternative avenues to modulate the postnatal wound healing response. This will have implications not only in the management of complications of dermal wound healing (bum contractures, keloids, hypertrophic scars, non-healing ulcers, etc.) but also in all conditions where fibrosis is an undesired consequence, such as pulmonary fibrosis, strictures, peritoneal adhesions, hepatic fibrosis, etc. Furthermore, understanding how selectins modulate the inflammatory response in the fetus will reveal valuable information that may explain the predisposition of neonates and premature infants to infections. These may then provide opportunities to assist with the inflammatory responses in these children when they are most vulnerable. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen
E-Journals: PubMed Central3 PubMed Central (PMC) is a digital archive of life sciences journal literature developed and managed by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM).4 Access to this growing archive of e-journals is free and unrestricted.5 To search, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Pmc, and type “keloids” (or synonyms) into the search box. This search gives you access to fulltext articles. The following is a sample of items found for keloids in the PubMed Central database: •
Reduced growth-factor requirement of keloid-derived fibroblasts may account for tumor growth. by Russell SB, Trupin KM, Rodriguez-Eaton S, Russell JD, Trupin JS.; 1988 Jan; http://www.pubmedcentral.gov/picrender.fcgi?tool=pmcentrez&action=stream&blobt ype=pdf&artid=279596
The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 3 4
Adapted from the National Library of Medicine: http://www.pubmedcentral.nih.gov/about/intro.html.
With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print. 6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with keloids, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “keloids” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for keloids (hyperlinks lead to article summaries): •

CHAPTER 2. NUTRITION AND KELOIDS Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and keloids.
Finding Nutrition Studies on Keloids 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 “keloids” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

CHAPTER 3. CLINICAL TRIALS AND KELOIDS Overview In this chapter, we will show you how to keep informed of the latest clinical trials concerning keloids.
Recent Trials on Keloids The following is a list of recent trials dedicated to keloids.8 Further information on a trial is available at the Web site indicated. •
Genetic Analysis of Familial Keloids Condition(s): Keloid Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: The purpose of this study is to identify the gene or genes responsible for keloid formation. Keloids are raised scars on the skin that form after a minor injury. A tendency to develop keloids often runs in families, suggesting a possible genetic basis. People who have had a classic (butterfly-shaped or wound-overflowing) keloid for at least one year may be eligible for this study. In addition to these probands (original participants), family members over 12 years of age who have either classic or non-classic keloids and those 18 years of age or older without keloids may participate. Probands and family members with keloids will have a medical history focusing on skin problems-particularly keloids-and a skin examination. In some cases, with the subject's permission, photos of the keloids will be taken. All participants will have 35 milliliters (about 2 tablespoons) of blood drawn for DNA (genetic) testing and for measurement of blood proteins, including cytokines, which can affect other tissues and cause scarring. Part of the blood sample will be used for additional genetic studies unrelated to keloids. The samples will be coded for confidentiality. Study Type: Observational Contact(s): see Web site below

CHAPTER 4. PATENTS ON KELOIDS 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 “keloids” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on keloids, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Keloids By performing a patent search focusing on keloids, 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

Keloids
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 keloids: •
Bandage having a scar treatment pad for scar management and scar repair Inventor(s): Cox; Christopher D. (137 Whitetail Dr., Harrison City, PA 15636), Cox; Craig M. (R.D. 4, Box 271, Greensburg, PA 15601), Isenberg; Perry A. (R.D. 4, Box 271, Greensburg, PA 15601) Assignee(s): None Reported Patent Number: 6,284,941 Date filed: May 11, 1999 Abstract: A bandage for the treatment of dermal scars, keloids, wounds or abrasions by contacting the skin of the user. The bandage includes a flexible member having a first side and a second side and further having an adhesive located on the first side. A scar treatment pad such as a layer of silicone elastomer is attached by the adhesive to the first side of the flexible member. The bandage is used by placing the first side of the flexible member in contact with the skin of the user such that the layer of silicone elastomer substantially contacts a scarred area of the skin. The adhesive removably attaches the first side of the flexible member substantially in contact with an unscarred area of the skin of the user. The layer of silicone elastomer attached to the first side of the flexible member improves the cosmetic and functional aspects of the scarred area of the skin of the user. Excerpt(s): The present invention relates generally to the treatment of dermal scars, keloids, wounds and abrasions and, more particularly, to the application of silicone sheeting or silicone gel to dermal scars, keloids, wounds and abrasions for treatment thereof. It is known in the medical field to use silicone elastomer materials (hereinafter referred to as "silicone") for the treatment of dermal scars and keloids. Silicone is known to soften scar tissue and improve the cosmetic as well as functional aspects of dermal scars and keloids. In addition, recent research indicates that certain silicone compounds promote wound healing and decrease scarring. Although the biological mechanism for the therapeutic aspects of silicone when applied to the skin is not completely understood, it is known in the art that the therapeutic benefits are derived independently of the pressure applied to the scar surface. One prior art device that has made use of the beneficial aspects of silicone when applied to the skin is disclosed in U.S. Pat. No. 5,759,560 to Dillon. The Dillon patent discloses silicone thermoplastic sheeting for scar treatment. In particular, the Dillon patent discloses a composite structure that includes a surface layer of silicone elastomeric material applied to one side of a thermoplastic splinting material. The splinting material is shaped to fit the geometric form of the skin of the patient so that the surface layer of silicone is in uniform contact with the skin of the patient. The resulting silicone thermoplastic sheeting is in the form of a hard thermoplastic splint having the surface layer of silicone on one side and is intended to be repeatedly applied to the skin of the patient. The silicone thermoplastic sheeting material disclosed by the Dillon patent is not very userfriendly because of its hard form. The silicone thermoplastic sheeting material cannot be worn, typically, when the patient engages in ordinary daily activities because of its immobilizing nature.

Composition for the control of wound scar production Inventor(s): Lee; Raphael C. (Chicago, IL) Assignee(s): Massachusetts Institute of Technology (cambridge, Ma) Patent Number: 5,902,609 Date filed: October 25, 1996 Abstract: This invention pertains to a composition for controlling wound scar production containing a calcium antagonist and a protein synthesis inhibitor. The method can be used to minimize wound scars, such as hypertrophic wound healing disorders keloids and burn scar contractures in humans or other mammals, particularly those individually prone to excesssive scarring Calcium antagonist treatment can also be used to control diseases associated with excessive scarring. such as cirrhosis of the liver, constructive pericarditis Dupuytren's disease of the hand, plantar fibrosis of the foot, and various other fibromatoses. Excerpt(s): The ability to heal by forming scars is essential for mammalian systems to survive wounding after injury. Normally, wound healing is a continuous process extending over a one-to-two-year period The process can be conceptually divided into three fundamentally distinct stages. The first stage is an intensely degradative phase called the inflammatory stage It occurs immediately after injury and provides a leans to remove the damaged tissues and foreign matter from the wound. Two-to-three days later, as fibroblasts from the surrounding tissue move into the wound, the repairing process enters its second stage, the proliferation and matrix synthesis stage. The fibroblasts in the wound proliferate and actively produce macromolecular such as collagen and proteoglycans, which are secreted into the extracellular matrix. The newlysynthesized collagen fibrils are cross-linked by lysyl oxidase and provide structural integrity to the wound. During this stage, fibroblasts also contract the intact collagen in order to reduce the surface area of the wound. This second stage lasts about three weeks. In the final, remodeling stage, the previous randomly-organized collagen fibril is aligned in the direction of mechanical tension and becomes more organized so that the mechanical strength of the wound area can be increased. The repair process is accomplished when the chemical and physical barrier functions of the skin are restored. Normal wound healing follows a well-regulated course. However, imbalances may cause abnormal scars to form. For example if the biosynthetic phase continues longer than necessary or degradation of collagen decreases, hypertrophic scars may form. These scars cause problems ranging from aesthetic deformity to severe limitation of motion. Hypertrophic scars more frequently occur among children and adolescents, suggesting that growth factors may influence the development of this type of scar. Hypertrophic scars are especially common in patients who have burns or wounds that heal by secondary intention. Another type of excess scar is the keloid. In this disorder, the cells appear to lace sensitivity to normal feedback signals. They are larger than hypertrophic scars and grow in an unregulated way, tending to invade normal tissue surrounding the wound. They rarely disappear spontaneously and often recur after surgical excision. The management of these scars remains a major unsolved clinical problem.

Control of wound scar production Inventor(s): Lee; Raphael C. (Chicago, IL) Assignee(s): Arch Develop. (chicago, Il), Massachusetts Institute of Technology (cambridge, Ma) Patent Number: 5,569,678 Date filed: February 1, 1994 Abstract: This invention pertains to a method for controlling wound scar production by administering a calcium antagonist, alone or in a combination with or followed by a steroid, to the wound site. The method can be used to minimize wound scars, such as hypertrophic wound healing disorders, keloids and burn scar contractures in humans or other mammals, particularly those individually prone to excesssive scarring. Excerpt(s): The ability to heal by forming scars is essential for mammalian systems to survive wounding after injury. Normally, wound healing is a continuous process extending over a one-to-two-year period. The process can be conceptually divided into three fundamentally distinct stages. The first stage is an intensely degradative phase called the inflammatory stage. It occurs immediately after injury and provides a means to remove the damaged tissues and foreign matter from the wound. Two-to-three days later, as fibroblasts from the surrounding tissue move into the wound, the repairing process enters its second stage, the proliferation and matrix synthesis stage. The fibroblasts in the wound proliferate and actively produce macromolecules, such as collagen and proteoglycans, which are secreted into the extracellular matrix. The newlysynthesized collagen fibrils are cross-linked by lysyl oxidase and provide structural integrity to the wound. During this stage, fibroblasts also contract the intact collagen in order to reduce the surface area of the wound. This second stage lasts about three weeks. In the final, remodeling stage, the previous randomly-organized collagen fibril is aligned in the direction of mechanical tension and becomes more organized so that the mechanical strength of the wound area can be increased. The repair process is accomplished when the chemical and physical barrier functions of the skin are restored. Normal wound healing follows a well-regulated course. However, imbalances may cause abnormal scars to form. For example, if the biosynthetic phase continues longer than necessary or degradation of collagen decreases, hypertrophic scars may form. These scars cause problems ranging from aesthetic deformity to severe limitation of motion. Hypertrophic scars more frequently occur among children and adolescents, suggesting that growth factors may influence the development of this type of scar. Hypertrophic scars are especially common in patients who have burns or wounds that heal by secondary intention. Another type of excess scar is the keloid. In this disorder, the cells appear to lack sensitivity to normal feedback signals. They are larger than hypertrophic scars and grow in an unregulated way, tending to invade normal tissue surrounding the wound. They rarely disappear spontaneously and often recur after surgical excision. The management of these scars remains a major unsolved clinical problem. Existing therapy for hypertrophic scars and keloids includes surgery, mechanical pressure, steroids, x-ray irradiation and cryotherapy. There are many disadvantages associated with each of these methods. Surgical removal of the scar tissue is often incomplete and can result in the development of hypertrophic scars and keloids at the incision and suture points. Steroid treatments are unpredictable and often result in depigmentation of the skin. X-ray therapy is the only predictably effective treatment to date; however, because of its potential for causing cancer, it is not generally recommended or accepted.

External tissue expansion device for breast reconstruction, male pattern baldness and removal of nevi and keloids Inventor(s): Ger; Ralph (Lake Success, NY), Oddsen; Robert (Centerport, NY) Assignee(s): Progressive Surgical Products (westbury, Ny) Patent Number: 6,254,624 Date filed: October 6, 1999 Abstract: An external tissue expansion device applies constant continuous low grade force to skin to obtain additional tension free skin and subcutaneous tissue prior to a surgical procedure. The device consists of two suture plates each being laminated structure of steel and an adhesive attached foam cushion. On the each end of one suture plate is a housing that contains a constant force spring placed over a post. The ends of the constant force spring protrude from the housing and there is a hook attached to the end of the constant force spring. On each end of the other suture plate there is a housing, with a opening that can accept the hook of the opposite suture plate. These suture plates are constructed so that they can be manually shaped to conform to the topography of the body part to be corrected and are attached to skin near the defect to be corrected prior to a surgical procedure. When the hooks from one suture plate are inserted into the openings of the housing of the other suture plate, the constant force springs pulls the suture plates together and over a time period stretches and expands skin and subcutaneous tissue external from the suture plates and accumulates this additional tension free skin and subcutaneous tissue in the opening between the two suture plates. This invention further provides a method to permit breast reconstruction without the use of any prosthesis, whereby a surgeon expands a breast mound of the patient's own body tissue at a specific location consisting of tension free skin and subcutaneous tissue and shapes this breast mound into a breast. Excerpt(s): This invention is in the field of medical devices and techniques of tissue expansion that are used by plastic and general surgeons to obtain additional tension free skin and subcutaneous tissue prior to a surgical procedure to correct a defect or to cover an implantable prosthesis. Such surgical procedures include breast augmentation and breast reconstruction after mastectomy, removal of a nevus or keloid, removal of malignant or benign lesions, improvement of cosmetic appearance and other plastic reconstructive procedures of the body that require tension free skin and subcutaneous tissue without distortion of nearby body structures. Also the new invention can be used in new surgical procedures to correct male pattern baldness and for breast reconstructive surgery and removal of nevus, hypertrophic scars or keloids. It is a surgical axiom that wound tension should be avoided at all costs. In surgical procedures a certain amount of skin may be excised and easily closed but there is a point beyond which closure results in wound tension or the wound cannot be closed resulting in a deficit of skin. Skin tension is of particular importance in wound healing because a highly stressed wound environment delays wound healing. A wound sutured closed under tension will result in maximum scarring. Wound tension is also one of the factors for initiation of a keloid or hypertropic scar. For the plastic surgeon the qualitative end result is one of the most crucial factors in reconstructive surgery. The attention to minute details can be the difference between success and failure for plastic surgical procedures where cosmetic appearance is a critical factor. Tension free skin is especially important in facial areas or when skin coverage is required to cover a prosthesis.

Keloids
Wounds closed under tension can create distortions of nearby facial features such as eyelids, lips, etc., create wide displeasing scars or result in exposure of an implantable prosthesis. The physician has three surgical means to obtain additional tension free skin namely: (A) skin grafts, (B) free flaps and (C) internally placed tissue expansion devices.

Facilitation of keloid healing with CM101/GBS toxin Inventor(s): Abramovitch; Rinat (Mordechai, IL), Hellerqvist; Carl G. (Brentwood, TN), Neeman; Michal (Mazkeret Batya, IL), Wamil; Barbara D. (Nashville, TN) Assignee(s): Vanderbilt University (nashville, Tn), Yeda Research & Development Ltd. (rehovot, Il) Patent Number: 6,569,838 Date filed: October 7, 1998 Abstract: The present invention includes a means of treating a patient having a keloid. Specifically, the invention includes a method for excising the keloid and administering a GBS toxin isolated from Group B.beta.-hemolytic Streptococcus bacteria. Excerpt(s): This invention relates to the facilitation of wound healing in patients, by minimizing scarring and accelerating healing. This invention also relates to the reduction of wound-related tumor progression. The normal process of healing a skin wound that has been surgically induced or is the result of trauma involves formation of a blood clot and, often, a scab. More particularly, first intention, or primary healing, generally occurs at clean incisions, whereas second intention, or secondary healing, occurs where wound edges are far apart. The protein fibrin holds the edges of the skin surrounding the wound together and the scab seals the wound and staves off infection. While an inflammatory response brings increased numbers of blood cells to the area to aid in the repair process, epithelial tissue regenerates and capillaries grow from blood vessels at the edges of the wound. The capillaries revascularize the area of the wound and contribute to the formation of granulation tissue which, in turn, causes scarring. Granulation tissue begins to form in the wound site and fills the site approximately five days after wound induction. Granulation tissue contains new collagen, fibroblasts, new blood vessels and inflammatory cells, especially macrophages (E. Rubin and J. L. Farber, Pathology, Lippincott, publ., pp. 85-95 (1994)). After seven to ten days, the wound has regained only 10% of the tissue's original strength. Web site: http://www.delphion.com/details?pn=US06569838__

The invention also relates to a silicone sheeting cushion enclosing silicone beads, polymeric pieces or bodies made of polyfluoroethylene sheeting or a related polymer which produces a negative static charge or, preferably, a silicone sponge or hydrophobic gel, most preferably silicone gel. Excerpt(s): This invention relates to the treatment of keloid and hypertrophic scars by covering the scar with a gas or gel-filled cushion made of silicone sheeting. It relates particularly to a cushion in the form of a hollow bag filled with completely dry air or an inert gas or gel. The invention also relates to a silicone sheeting cushion enclosing silicone beads, polymeric pieces or bodies made of TEFLON sheeting or a related polymer which produces a negative static electrical charge or, preferably, a silicone sponge or gel. Keloid and hypertrophic scars appear on the skin after injury or acne or spontaneously in the shape of a hard bump or swelling which usually causes much distress, both aesthetic and functional, besides pain, it causes both itching and burning sensations and can become a lifelong problem unless medically treated. Silicone gel or occlusive sheeting is widely used at present for the treatment of hypertrophic and keloid scars without any scientific explanation as to its mode of action. See, Ahn, et al., Surgery, 106:781-787 (1989), Mercer N. S. G., Br J Plast Surg, 42:83-87, (1989); Perkins, et al., Burns, 9:201-204, (1982); Quinn K.

With this treatment, softening and flattening of the scar was experienced after from 7 to 12 months of continuous covering of the scar. Professor B. Hirshowitz and other researchers recently noted that rubbing contact with silicone sheeting creates a static electric field which, they believe, acts on the scar, prompting its reversal to normal tissue.

Human cardiac/brain tolloid-like protein Inventor(s): Arleth; Anthony J (Hatfield, PA), Elshourbagy; Nabil A. (West Chester, PA), Li; Xiaotong (Devon, PA), Willette; Robert N (Pottstown, PA) Assignee(s): Smithkline Beecham Corporation (philadelphia, Pa) Patent Number: 6,008,017 Date filed: December 16, 1997 Abstract: HC/BTLP polypeptides and polynucleotides and methods for producing such polypeptides by recombinant techniques are disclosed. Also disclosed are methods for utilizing hC/BTLP polypeptides and polynucleotides in the design of protocols for the treatment of restenosis, atherosclerosis, congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), benign prostatic hypertrophy (BPH), nephritis, fibrosis, glomerulonephritis, gliosis, cirrhosis and anomalies of wound healing, such as keloids among others, and diagnostic assays for such conditions. Excerpt(s): This invention relates to newly identified polynucleotides, polypeptides encoded by them and to the use of such polynucleotides and polypeptides, and to their production. More particularly, the polynucleotides and polypeptides of the present invention relate to the astacin protein family, hereinafter referred to as human cardiac/brain tolloid-like protein (hC/BTLP). The invention also relates to inhibiting or activating the action of such polynucleotides and polypeptides. The hC/BTLP gene appears to possess all of the important protein domains present in the bone

morphogenetic protein (BMP)-1/procollagen C-proteinase (PCP) protein. Members of the astacin family of metalloproteinases, such as BMP-1, have previously been linked to cell differentiation and pattern formation during development through a proposed role in the activation of latent growth factors of the TGF-.beta. superfamily. In addition, recent findings indicate that BMP-1 is identical to PCP, which is a metalloproteinase involved in the synthesis of matrix collagen. This observation suggests that a functional link may exist between astacin metalloproteinases, growth factors and cell differentiation and pattern formation during development, as well as fibrotic processes characterized by the accumulation of matrix collagen. Nucleotide and amino acid sequence homologues suggest that hC/BTLP, like BMP-1, possesses PCP activity. PCP activity is one of the essential enzymatic steps required for the extracellular production of insoluble collagen fibrils from soluble procollagen. However, mouse mammalian tolloid-like protein is the most closely related homologue of hC/BTIP. Mouse mammalian tolloid-like protein and BMP-1 are distinct gene products with differential tissue distribution. Based on cross-species comparisons, the regulation and distribution of hC/BTIP would be expected to be distinct from BMP-1. Indeed, mouse mammalian tolloid-like protein exhibits a unique tissue distribution when compared to BMP-1. Thus, the selective inhibition of matrix collagen accumulation is important in highly localized fibrotic disorders, e.g., gliosis associated with neurotrauma and ventricular fibrosis associated with congestive heart failure. This indicates that the astacin protein family has an established, proven history as therapeutic targets. Web site: http://www.delphion.com/details?pn=US06008017__ •

Lotion-based sulfur preparation for skin treatment Inventor(s): Boyce; Reginald D. (2882 Hosta Dr., Charlotte, NC 28269), Phillips; David L. (1054 White Plains Rd., Charlotte, NC 28213) Assignee(s): None Reported Patent Number: 5,716,606 Date filed: August 24, 1995 Abstract: A topical composition for treatment of dermatitic conditions, particularly keloids and hypertrophic scars, is provided which comprises sulfur of at least approximately forty weight percent in a spreadable carrier base. Excerpt(s): The present invention relates generally to preparations for treating the skin and, more particularly, to a preparation for treatment of the skin that contains a high concentration of sulfur. Sulfur is known to have properties that aid in the treatment of dermatitic conditions. It is employed in various forms for its germicidal, fungicidal, and keratolytic actions. However, current applications of sulfur to treat dermatitic conditions maintain a very low weight percentage of sulfur in the composition. For example, Fostex Medicated Cover-up, manufactured by Westwood, is an acne cream that contains only two percent sulfur. Liquimat, manufactured by Owen/Allercreme, is a lotion for treatment of acne that contains only five percent sulfur. Xerac, manufactured by Person & Covey, is a gel for the treatment of acne that contains only four percent of a microcrystalline sulfur. While these compositions do provide for treatment of dermatitic conditions, they use relatively small percentages of sulfur. In U.S. Pat. No. 4,520,012, issued to Alfonsi, flowers of sulfur, also known as sublimed sulfur, is used in a composition for topical application to improve hair growth. The Alfonsi patent uses a concentration of sulfur of between one and three weight percent and teaches away from the use of any greater concentration of sulfur by stating that greater concentrations do not result in improvement of the effectiveness of the composition.

Method for the prevention and treatment of scars with enzymes Inventor(s): Pinnell; Sheldon R. (Durham, NC) Assignee(s): Biospecifics, NV (curacao, An) Patent Number: 4,645,668 Date filed: March 27, 1985 Abstract: The method for preventing and for treating mammalian cicatrices such as keloids, acne scars, hypertrophic scars, wrinkles, cellulite and neoplastic fibrosis which comprises intra-dermal injection of effective amounts of a pharmacologically suitable solution of the enzymes collagenase, elastase, papain, plasminogen activator, plasmin, mast cell protease or lysosomal hydrolase, individually, and one or more of such enzymes in combination with the enzyme hyaluronidase. Excerpt(s): Collagen is the major structural constituent of mammalian organisms and makes up a large portion of the total protein content of skin and other parts of the animal body. In humans, it is particularly important in the wound healing process and in the process of natural aging. Various skin traumas such as burns, surgery, infection and accident are often characterized by the erratic accumulation of fibrous tissue rich in collagen and having increased proteoglycan content. In addition to the replacement of
70
Keloids
the normal tissue which has been damaged or destroyed, excessive and disfiguring deposits of new tissue sometimes form during the healing process. The excess collagen deposition has been attributed to a disturbance in the balance between collagen synthesis and collagen degradation. Keloids are tumors or connective tissue consisting of highly hyperplastic masses which occur in the dermis and adjacent subcutaneous tissue in certain susceptible individuals, most commonly following trauma. The known therapies for keloids have had limited success and they frequently can recur in the site after surgical removal. Hypertrophic scars are unsightly masses which can result from burns or other injuries to the skin. Such scars are usually permanent and resistant to known methods of therapy.

Method for the selective dissolution of cancer cells using a composition derived from the photosynthetic system of plants and mammalian embryonic tissue Inventor(s): Lofflmann; Adolf (Munchner Strasse 7, 8000 Munich 70, DE) Assignee(s): None Reported Patent Number: 5,516,754 Date filed: January 24, 1994 Abstract: By the combined use of an agent which selectively dissolves tumor cells and which contains a protein fraction which has oxygen-liberating action and which is derived from the photosynthetic system of plants, together with a further agent which inhibits the proteases of the cancer cells and which has been obtained by means of extraction of embryonic tissue or maternal uterus tissue from placentals, it is possible to selectively dissolve the tumor by means of this agent without damaging the healthy organism. When used on its own, the abovementioned plant-derived agent shows an activity in the treatment of inflammatory processes and is also suitable for the aftertreatment of scars, keloids and damage caused by ionizing rays. Excerpt(s): The invention relates to the use of certain substances which are illustrated below in greater detail, based on a novel concept in medical science, as an active substance in pharmaceuticals, in particular for the selective dissolution (destruction) of cancer cells (malign tumor cells), but also for combating inflammatory processes, and for the treatment of hypertrophic scars and keloids. The present invention is based on considerations that one of the reasons why scientific attempts to date to understand and combat cancer may have remained so unsatisfactory is because the underlying idea that the phenomenon of cancer is causally linked to the cell nucleus has blurred focusing on fundamentally novel, promising concepts. Cancer cells differ from healthy cells by a series of properties, and successful cancer therapy should, if possible, be orientated towards these properties which distinguish cancer cells from healthy cells so as to be able to choose a therapy route which selectively only targets cancer cells, or selectively only damages cancer cells. However, numerous known methods in cancer therapy do not meet these requirements since, like most cytostatic agents and rays, for example, they do not selectively act on cancer tissue, but also damage normal healthy tissue. A method for destroying tumors, which is known from the literature, is described in Nachr. Chem. Tech. Lab. 33 (1985), No. 7 "Lokalisierung und Therapie von Tumoren mit Porphyrinen [Tumor localization therapy with porphyrins]", H. Vandenbergh and P. Cornaz. This method combines injections with a haematoporphyrin derivative with redlight irradiation. The present invention is based on the known observation that cancer cells differ from healthy cells in that they have an "anoxemic metabolism" which is
Patents 71
characterized by the occurrence of aerobic glycolysis. Starting from this medical fact, the consideration was that therapy which, in a targeted manner, aims at the cell respiration of cancer cells, which differs from that of healthy cells, can selectively damage the former without simultaneously attacking healthy cells. However, when this concept was pursued, it emerged that further peculiarities of cancer cells compared with normal cells have to be taken into account if therapy is to be successful, and that valuable model hypotheses can be put forth if the cancer cell is regarded as a cell which, in total, mimics embryonic behavior (embryonic encoding). However, the properties exhibited by cancer cells similar to embryonic cells, include not only the anoxemic cell metabolism, but also the fact that proteases are active, which imparts the ability of "incipient digestion" of body tissue (maternal uterus tissue or healthy tissue of the cancer patient) to the cancer cells and to the embryonic cells.

Method for the treatment of scars and keloids Inventor(s): Reinmuller; Johannes (Gustav-Frcytag-Strasse 27, 65189 Wiesbaden, DE) Assignee(s): None Reported Patent Number: 5,731,298 Date filed: August 15, 1994 Abstract: A method and a pharmaceutical composition for non-topical wound, scar and keloid treatment is described which contains cross-linked glycosaminoglycans and conventional pharmaceutical auxiliary and/or carrier substances. The pharmaceutical composition is preferably administered intralesionally e.g. by injection in the form of a gel containing water. The cross-linked glycosaminoglycans are also suitable for use as cosmetics and skin care products. Excerpt(s): This is in an application under 35 U.S.C.sctn.371 of PCT/EP92/02990 having an international filing date of Dec. 24, 1992. The invention concerns a pharmaceutical composition for the treatment of wounds, scars and keloids. Excess new growth of scar tissue occurs in many people during healing of skin wounds. In medical terminology this new formation of tissue is referred to as cicatricial hypertrophy or as keloid in severe cases. These are unpredictable reactions during wound healing caused by a predisposition. Up to now the reasons for excess cicatrisation are not known. Thus at present there is also no scientifically based causal method of treatment. Web site: http://www.delphion.com/details?pn=US05731298__

Excerpt(s): The present invention is related to a process and composition for topically inhibiting Protein Kinase C. More particularly, the present invention relates to topically applying the composition disclosed herein in order to treat the affected skin or underlying structures of humans and animals. Protein kinase C inhibitors have been shown effective in vitro and in a limited fashion orally, but not efficacious when used topically. What is needed is a topical composition which is safe and cost effective. Mukhtar in Pharmacology of the Skin describes the communication between cells as being mediated by different biomolecules, such as hormones. These so called primary messengers bind to specific receptors on the cell surface. The binding of a primary messenger to its receptor conveys a certain information to the cell which is subsequently transduced through the membrane by a chain of signaling. This process involves various membrane structures and leads to the activation of an enzyme located at the intracellular side of the membrane. The stimulated enzyme generates a second messenger which evokes the cellular response; in most cases, by the activation of other enzymes. By these steps, the initial extracellular signal is converted into an intracellular signal. This process is called signal transduction. Protein kinases regulate cellular responses by phosphorylation of substrate proteins (eg. receptors or enzymes) and thereby alter their state of activity. In the case of the inositide cascade, PKC mainly performs this reaction. Sphingosine dose-dependently inhibits PKC, but also binds to calmodulin (CaM) function and therefore inhibits CaM function. Keratinocyte intercellular adhesion molecule-1 (ICAM-1) is thought to be involved in dermal lymphocyte infiltration. The PKC activating phorbol ester, PMA has been reported to induce the expression of ICAM-1 in normal human keratinocytes. This effect can be blocked by a PKC inhibitor and suggests that PKC might play a regulatory role in ICAM-1 expression. Web site: http://www.delphion.com/details?pn=US06306383__ •

Surgical skin closure Inventor(s): Romero-Sierra; Cesar Aurelio (Bath, CA), Tanner; Joseph A. (Ottawa, CA) Assignee(s): Canadian Patents and Development Limited (ottawa, Ca) Patent Number: 4,038,989 Date filed: May 7, 1976 Abstract: A therapeutic device for skin lesions is provided in which adhesively coated flexible strips are stuck to skin on opposed sides of the lesion, aligned to prevent lateral displacement of the skin and drawn together by flaps to close the skin over the lesion. This device allows the lesion to heal without the formation of keloids. The flaps may be pulled around the side bars of a buckle member to draw the flexible strips to close skin over the lesion, and then the flaps stuck to the flexible strips to hold the skin closing the lesion. For surgical incisions a transparent, removable cover may be on the folded back flaps, and the surgical incision made through the transparent, removable cover, markings on the strips may be used to align them, and the lesion may be closed by sticking the flaps together in face-to-face relation. Excerpt(s): This invention relates to a therapeutic device for skin lesions. It has already been proposed by Claude Kawchitch in an article "No-Scar Surgery Zip-Fastener", in The Medical Technologist, Volume 4, No. 4, April, 1974, to provide a surgical zip (slide) fastener to eliminate operation scars and close a wound quickly and securely and heal a wound in a faster manner than with conventional, surgical stitching. After the surgeon has pencilled the surgical cutting line on the skin, a foundation stage of the zip fastener in the form of a self-adhesive, translucent ribbon is stuck over the pencilled line so that the two ends of the line protrude as cutting guides. The self-adhesive, translucent ribbon, which has extra strong adhesive on its silicone-rubber underside, is filled with cellular foam and is capped with a perforated nylon top layer. Protruding hooks are provided on the nylon and are used later to attach the ribbon to a concertina spring forming the zip (slide) fastener. With the self-adhesive ribbon stuck over the pencilled line the surgeon cuts through the self-adhesive, translucent ribbon along the pencilled line and into the flesh. When it is time to close the wound the surgeon pushes the two cut edges together and then stretches the concertina spring so that it narrows, clasps it to the nylon hooks, sticks both ends of the spring to the skin with adhesive plaster and the wound is neatly fastened together without the conventional, surgical stitching.

Synducin mediated modulation of tissue repair Inventor(s): Bernfield; Merton (Boston, MA), Gallo; Richard L. (Natick, MA) Assignee(s): Children's Medical Center Corporation (boston, Ma) Patent Number: 5,654,273 Date filed: September 22, 1994 Abstract: The membrane permeating antibacterial peptide, PR-39, previously found only in the intestine, was purified from wound fluid and shown to possess syndecan-1 and syndecan-4 inductive activity specifically in mesenchymal cells. This is a newly recognized function that defines peptide containing syndecan-inducing activity, and that are known as synducins. Therefore a molecule with both antimicrobial and synducin activities is deposited in wounds where it can simultaneously reduce infection and influence the action of growth factors, matrix components, and other cellular effectors involved in wound repair. Synducins, including PR-39, and derivatives thereof, is therefore useful in the modulation of wound healing, as well as other disorders involving mesenchymal cells and cell surface molecular interaction, including metastatic disease, angiogenesis, restenosis, stasis or decubitis ulcers, and prevention of keloids. Excerpt(s): This invention is generally in the area of modulation wound repair using a peptide inducer of syndecan expression. Complex cellular behaviors such as those resulting in wound repair are influenced by a variety of soluble growth factors, cytokines, and insoluble extracellular matrix components. To exert their effects, many of these effector molecules must bind to the heparan sulfate chains that are at the surface of nearly all adherent cells (Ruoslahti and Yamaguchi, Cell, 64:867 (1991)). For example, interaction with cell surface heparan sulfate is required for cells to respond to the growth factors FGF-2 (Rapraeger, et al., Science, 252:1705 (1991); Yayon, et al. Cell, 64:841 (1991)) and HB-EGF (Higashiyama, et al., J. Cell Bio., 122:933-940 (1993)), and to the matrix component fibronectin (Guan, et al. Cell Reg., 2:951 (1991); Woods, et al., Molec. Biol. Cell, 4:605 (1993)). Indeed, Guan, et al. (1991); Bernfield, et al., in Annu. Rev. Cell Biol., G. E. Palade, B. M. Alberts, J. A. Spudich, Eds. (Annual Reviews Inc., Palo Alto, Calif., 1992), 8:365-393); Jalkanen, et al., Trends in Glyco-science and Glycotech, 5:107 (1993); G. David, FASEB J., 7:0123 (1993); and A. C. Rapraeger, Curr. Opin. Cell Biol., 5:844 (1993)) have proposed that cell surface heparan sulfate, which is derived mostly from the four members of the syndecan family of transmembrane proteoglycans (G. David, et al., J. Cell Biol., 111:3165 (1990)), acts together with specific signaling receptors to mediate the cellular response to such effectors. Changes in the abundance of cell surface heparan sulfate probably regulates the action of these effector molecules, yet it is not known how the amount of heparan sulfate at the cell surface is controlled. Cell surface heparan sulfate mediates the activity of several growth factors, extracellular matrix components, proteases and other cellular effectors involved in wound repair. Syndecan-1, a major transmembrane heparan sulfate proteoglycan, is induced transiently on mesenchymal cells during the repair of skin wounds. Accordingly, induction of syndecan-1 can influence this process. Syndecan-1 induction can trigger cellular behaviors such as proliferation and migration that are involved in wound repair due to its ability to bind and thus augment the action of heparin-binding growth factors, including FGF-2, HB-EGF, and PDGF-AB, each found in repairing wounds. Cell surface syndecan-1 can also bind fibronectin, thrombospondin, tenascin and the fibrillar collagens. Accordingly, its induction can contribute to the effects of these extracellular
Patents 75
matrix components that are involved in wound repair. Thus, the induction of syndecan1 by PR-39 may mediate growth factor responsiveness and the changes in cell proliferation, migration, and adhesion that must take place for wound repair to proceed.

Topical formulation of alkyl-, phenyl-pyridone Inventor(s): Scheiwe; Max Werner (Maulburg, DE), Yamauchi; Shitotomo (Tokyo, JP) Assignee(s): Mepha AG (aesch, Ch) Patent Number: 6,492,395 Date filed: May 23, 2001 Abstract: A pharmaceutically acceptable topical formulation for the treatment and/or prevention of skin ailments, more particularly of fibriotic nature such as fibriotic lesional tissues, contiguous warts, contact dermatitis, and keloids, and to assist the healing of burns after surgery, comprising as active ingredient a substituted pyridone of the formula: n-(R.sup.1)-R.sup.2 -2-(1H)pyridone or a pharmaceutically acceptable salt or ester thereof, where R.sup.1 is selected from methyl, ethyl, propyl, carboxyl and a carboxymethyl or carboxyethyl ester group, R.sup.2 is selected from phenyl, methylphenyl, ethylphenyl, propylphenyl, and a carboxyphenyl or carboxyethylphenyl ester group, and n is 3, 4 or 5, together with an excipient, characterized in that the excipient comprises, one or more plasticisers, one or more antioxidants, one or more gelforming agents and sufficient pH adjusting agent to bring the pH of the formulation to a value from 4 to 8. The preferred active ingredient is 5-methyl-1-phenyl-2-(1H)pyridone (Pirfenidone). Excerpt(s): or a pharmaceutically acceptable salt or ester thereof, where R.sup.1 is selected from methyl, ethyl, propyl, carboxyl and a carboxymethyl or carboxyethyl ester group, R.sup.2 is selected from phenyl, methylphenyl, ethylphenyl, propylphenyl, and a carboxyphenyl or carboxyethylphenyl ester group, and n is 3, 4 or 5 (position of substitution). The preferred active ingredient is Pirfenidone (CAS 53179-13-8, 5-methyl1-phenyl-2-(1H)-pyridone). As described in U.S. Pat. No. 5,310,562 and EP 0 383 591, Pirfenidone has a broad spectrum of applications in the prevention and treatment of fibrotic diseases, especially for the reparation and prevention of fibrotic lesional tissues, contiguous warts, contact dermatitis, keloids, fibrosis of the lung, fibrosis of the prostate, sclerosis, the healing of burns after surgery and Alzheimer disease. Although the possibility of topical application is mentioned, there is no description of any specific formulation. The application of active ingredients of the class mentioned, (hereafter called alkyl,phenyl pyridones) e.g. Pirfenidone for e.g. the treatment of burns and keloids may possibly be carried out using a solution or a suspension of the agent in aqueous or oily excipient such as emulsions, creams, ointments, gels, microemulsions, liquid emulsions, nanocapsule suspensions, liposome formulations, lotions and the like; however, an ointment, cream or gel formulation is preferable because of their soothing effect and easy application. Because these formulations are used in the treatment of humans they are considered to be pharmaceutical preparations, and as thus have to be proven to be physically and chemically stable before they are permitted on the market. For this reason, each formulation must undergo a stability test. Without the necessary data on stability and shelf life, the formulation cannot be approved by any health authority.

Keloids
Treatment of skin disorders Inventor(s): Nagler; Arnon (Jerusalem, IL), Pines; Mark (Rehovot, IL) Assignee(s): Hadasit Medical Research Services and Development Company Ltd (jerusalem, Il) Patent Number: 6,211,188 Date filed: February 11, 1997 Abstract: An effective treatment for skin disorders characterized by abnormal skin cell behavior, including a pharmaceutically effective amount of Halofuginone. Skin disorders which can be treated include keloids, hypertrophic scars, psoriasis, acne, seborrhea and alopecia. Halofuginone can reduce or eliminate clinical symptoms of these disorders, as well as substantially prevent the formation of keloids and hypertrophic scars. Excerpt(s): The present invention relates to a method and a composition for the treatment of skin disorders and, more particularly, to a method and a composition for the treatment and prevention of psoriasis, hypertrophic scars and keloids. Keloids are benign fibrotic tumors which are believed to arise from the reticular dermis. They are characterized by increased tissue fibrosis and collagen deposition [Friedman, D. W. et al., J. Surg. Res., Vol. 55, p. 214-222, 1993]. Keloids usually first appear when a patient is between the ages of 10 and 30 years, and are often associated with trauma. They occur most commonly on the upper back, anterior chest, shoulders and ear lobes. Keloids are especially frequently seen in patients of African or Asian descent. Hypertrophic scars are somewhat related to keloids, in that they are also characterized by increased tissue fibrosis and collagen deposition [Friedman, D. W. et al., J. Surg. Res., Vol. 55, p. 214-222, 1993]. Furthermore, hypertrophic scars are also most often seen in patients of African and Asian descent [Rockwell, W. B. et al., Plastic and Recon. Surg., Vol. 84, p 827-835, 1989]. Although there are certain differences between hypertrophic scars and keloids, such as a lower fibroblast density in keloids than in hypertrophic scars, a common mechanism is believed to underlie both conditions. Specifically, a geneticallydetermined aberration of the metabolism of melanocyte-stimulating hormone (MSH) is believed to be responsible for both hypertrophic scars and keloids [Rockwell, W. B. et al., Plastic and Recon. Surg., Vol. 84, p. 827-835, 1989]. Thus, both hypertrophic scars and keloids represent the effects of genetically abnormal behavior of skin cells.

Attenuation of fibroblast proliferation Inventor(s): Cauchon, Elizabeth; (Ile Perrot, CA), Denholm, Elizabeth M.; (Pointe Claire, CA), Silver, Paul J.; (Spring City, PA) Correspondence: Patrea L. Pabst; Arnall Golden & Gregory, Llp; 2800 One Atlantic Center; 1201 West Peachtree Street; Atlanta; GA; 30309-3450; US Patent Application Number: 20020102249 Date filed: December 1, 2000 Abstract: Highly purified and specific glycosaminoglycan degrading enzymes, chondroitinase B and chondroitinase AC, are used to treat fibroproliferative diseases. The enzymatic removal of chondroitin sulfate B (dermatan sulfate), and to a lesser extent, chondroitin sulfate A or C, from cell surfaces effectively decreases growth factor receptors on the cells and thereby decreases the cell proliferative response to such growth factors. In addition, removal of chondroitin sulfates reduces secretion of collagen, one of the major extracellular matrix components. Through the combined inhibition of fibroblast proliferation and collagen synthesis, treatment with chondroitinase B or chondroitinase AC decreases the size of fibrous tissue found in psoriasis, scleroderma, keloids, pulmonary fibrosis and surgical adhesions. Excerpt(s): The present invention is a method and composition using chondroitinase B and chondroitinase AC, glycosaminoglycan degrading enzymes, to inhibit the formation of fibrotic tissue. This application claims priority to U.S. Ser. No. 60/168,518, filed Dec. 2, 1999. Proteoglycans on the cell surface and in the extracellular matrix contain variable glycosaminoglycan chains, which include heparan sulfate and chondroitin sulfates A, B, or C. While some proteoglycans contain only one type of glycosaminoglycan, others contain a mixture of heparan and chondroitin sulfates (Jackson et. al., Physiol. Rev. 71:481-530,1991). Extracellular proteoglycans form a structural framework for cells and tissues, and together with cell-associated proteoglycans, have major functions in regulating cell adhesion, migration, and proliferation. The functions of proteoglycans and their component parts have been extensively studied, with much of the emphasis on the roles of heparin and heparan sulfate on cell metabolism (Kjellen, L., and Lindahl, U. (1991) Ann. Rev. Biochem. 60:443-475; Vlodavsky, et al. (1995) Thrombosis Haemostasis 74:534-540; Yayon, et al. (1991) Cell 64:841-848)). Much less is known about the biological activities of proteoglycans containing chondroitin sulfate glycosaminoglycans, and in particular, their effects on cell proliferation.

Human fibrotic responses to surgery and methods of treatment Inventor(s): Spencer, E Martin; (San Francisco, CA) Correspondence: E Martin Spencer; 505 Ortega Street; San Francisco; CA; 94122; US Patent Application Number: 20020107185 Date filed: December 9, 2000 Abstract: This invention is a method for selectively preventing an unwanted fibrotic response in humans after surgery or injury using therapeutic amounts of human insulinlike growth factor binding protein-4 (IGFBP-4) that has been modified to resist the enzymatic action of the natural IGFBP-4 protease in tissues. Surgical procedures in the abdomen, pelvis, thorax, and spinal column frequently initiate the formation of fibrous adhesions between organs. Collagen is the principal constituent of fibrous adhesions. These abnormal connections may interfere with the normal function of the organs involved, cause pain, and require additional surgical procedures, which frequently induces more adhesion formation. Surgical incisions and burns may directly initiate a process in tissues that stimulates excess fibrous tissue and results in hypertrophic scars or keloids that are disfiguring and/or interfere with function. At times a decreased fibrotic response is required by plastic surgeons for cosmetic reasons and by ophthalmologists for glaucoma patients to maintain patency of holes created in the sclera (sclerectomy) to filter fluid from the anterior chamber of the eye. Insulin-like growth factor-I (IGF-I) is one of the components that stimulates the adhesion process and wound repair. Lowering the level of IGF-I in the body significantly impairs wound healing and the synthesis of collagen. Lowering the level of IGF-I in the specific site of the body at which adhesions are undesirable significantly impairs the formation of adhesions and decreases the fibrotic response in wounds. IGFBP-4 inhibits the formation of fibrous tissue by binding and inactivating IGF-I. The protease resistant, modified IGFBP-4 is superior to the natural IGFBP-4 for this purpose. Excerpt(s): This invention relates to the fibrotic response in humans resulting from surgery or trauma and methods to inhibit this response. Normal wound healing consists of a coordinated series of reactions that restore the integrity of the tissue. The stages are: Hemostasis, inflammation, proliferation, matrix formation, and remodeling. Hunt T. K., "Wound healing: Disorders of repair, in" Fundamentals of Wound Management in Surgery, (Chirurgeocom 1976). After hemostasis is achieved, granulocytes appear followed by macrophages. Macrophages are critical to healing and direct the subsequent events by the production of cytokines, polypeptides and proteins that regulate cellular functions. Fibroblasts proliferate into the wound and synthesize collagen (fibrous
Patents 79
tissue), the major component of the matrix of the wound. This is followed closely by angiogenesis, which is the proliferation and in-growth of blood vessels. Subsequently, in the case of cutaneous wounds, epithelial cells on the edge proliferate and cover the wound. The final stage is remodeling which includes modification of the collagen tissue and contraction of the wound scar. IGF-I stimulates most of the phases of wound healing, especially the activity of macrophages and fibroblasts, which proliferate and synthesize collagen, elastin and proteoglycans. Spencer, et al., "Somatomedins: Do they play a pivotal role in wound healing?," Growth Factors and Other Aspects of Wound Healing: Biological and Clinical Implications, 103-116, (1988); Steenfos, et al., "Insulinlike Growth Factor 1 has a Major Role in Wound Healing," Surgical Forum, 68-70, (1989); Mueller, et al., "The role of IGF-I and IGFBP-3 in wound healing," in Modern Concepts of Insulin-like Growth Factors, ed.

Lectins as anti-fibrotic agents Inventor(s): Cantor, Jerome Owen; (Brooklyn, NY), Shteyngart, Bronislava; (Brooklyn, NY) Correspondence: Jerome O. Cantor, MD; 242 92nd Street; Brooklyn; NY; 11209; US Patent Application Number: 20030216300 Date filed: May 12, 2003 Abstract: The subject invention is directed to the treatment of tissue fibrosis by administration of an effective amount of lectin. Fibrosis herein refers to the accumulation of extracellular matrix constituents that occurs following trauma, inflammation, tissue repair, immunological reactions, cellular hyperplasia, and neoplasia. Examples of tissue fibrosis include, but are not limited to, pulmonary fibrosis, cirrhosis of the liver, skin scars and keloids, adhesions, fibromatosis, atherosclerosis, and amyloidosis. The treatment is intended for a variety of mammals, including humans. Excerpt(s): Lectins bind to carbohydrate moieties, e.g. acetylglucosamine, that are ubiquitous in the mammalian extracellular matrix. This suggests the possibility that lectins may be used to coat the matrix and limit further binding of collagen, elastin, and other connective tissue components to carbohydrate groups. The aggregation of large amounts of matrix constituents, as occurs in fibrosis, may therefore be subject to limitation by the introduction of lectins. This hypothesis was tested in our laboratory. Elastic fiber matrix prepared from cultured rat lung mesothelial cells (1,2) was first treated with tomato lectin (lycopersicon esculentum), then covered with hyaluronan (HA), which normally protects the matrix from degradation by elastases. It was found that lectin treatment abolished the protective effect of HA and facilitated breakdown of the elastic fiber matrix by elastase. Since the binding of HA to the elastic fibers is analogous to fibrosis in that it involves deposition of new matrix material (HA) over

existing matrix, the addition of lectin may provide a means of counteracting this process and preventing the formation of scar tissue. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
METHOD IF TREATING KELOIDS Inventor(s): BROWN, SANDRA; (SOUTHFIELD, MI) Correspondence: Thomas E Anderson; Gifford Krass Sprinkle; Anderson & Citkowski; 280 North Old Woodward Suite 400; Birmingham; MI; 48009 Patent Application Number: 20010038846 Date filed: May 10, 1999 Abstract: Disclosed is a method for treating keloid scaring. The method includes application of a concentrated solution of glycolic acid in the range of 20-70% by weight to the skin for a period of time sufficient to promote atrophy of the scar. After a sufficient time, the tissue is washed with soap and water to remove the acid and loosen tissue. Excerpt(s): This application claims the benefit of U.S. Provisional Application No. 60/085,165, filed May 12, 1998. Keloids are raised, hard, generally irregularly shaped scars which form on the skin as a result of trauma including burns, lacerations, abrasions, cryosurgery, vaccinations, and the like. Keloids are characterized by the presence of thick bands of acellular, eosinophilic collagen therein, and are thought to form as a result of a defective healing process. Keloids can occur in people of any race, but are more common in black people. In some instances, keloids can produce severe physical and psychological symptoms. Keloids are prone to bleeding and itching, and can be extremely sensitive to touch so that contact with clothing, or even water, can produce excruciating pain. Keloids can be highly disfiguring, and their untreatable nature has caused some patients to become recluses or even commit suicide. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Contact: Available online from Merck and Company, Inc. (800) 819-9456. Website: www.merck.com/pubs/mmanual_home/contents.htm. Also available from your local book store. PRICE: $29.95 plus shipping. Summary: This chapter provides the general public and people who have noncancerous skin growths with information on the symptoms and treatment of moles, atypical moles, skin tags, lipomas, angiomas, pyogenic granulomas, seborrheic keratoses, dermatofibromas, keratoacanthomas, and keloids. Moles are usually dark skin growths that vary in size, may be flat or raised, may be smooth or rough, or may have hairs growing from them. Moles are harmless and do not need to be removed unless they change. Atypical moles, which are flat or raised dark skin growths, may appear anywhere on the body. People who have atypical moles, especially those with a family history of melanoma, must have the moles examined at least once a year for any changes that might indicate malignant melanoma. Skin tags are soft, small, flesh colored or slightly darker skin flaps that usually occur on the neck, in the armpits, or in the groin. They can be removed by freezing them with liquid nitrogen or cutting them off. Lipomas are soft deposits of fatty material that grow under the skin and cause round or oval lumps. Lipomas are not cancers, and they rarely become cancerous. Bothersome lipomas may be removed by surgery or liposuction. Angiomas are collections of abnormally dense blood or lymph vessels that cause red or purple skin discolorations. Angiomas include port wine stains, strawberry marks, cavernous hemangiomas, spider angiomas, and lymphangiomas. Port wine stains are flat pink, red, or purplish discolorations that are present at birth. They are physically harmless, but may be psychologically harmful. These birthmarks can be covered with cosmetic cream or removed with a laser. Strawberry marks are raised, bright red areas that range in size from small to large. Oral prednisone may be taken to shrink them. Cavernous hemangiomas are raised red or purplish areas composed of abnormal, enlarged blood vessels. Treatment options include oral prednisone, electrocoagulation, or surgical removal. Spider angiomas are bright red areas with a central reddish or purplish spot with slender projections. They are common in pregnant women and women taking oral contraceptives. The central blood vessel can be destroyed by electrocoagulation. Lymphagiomas are bumps caused by a collection of enlarged lymphatic vessels. Treatment is not usually needed, but they can be removed surgically. Pyogenic granulomas, which usually occur after injury to the skin, are scarlet, brown, or blue black slightly raised areas caused by increased capillary growth and tissue swelling. They can be removed surgically or by electrocoagulation. Seborrheic keratoses are brown, black, or flesh colored growths that can appear anywhere on the body. Treatment is usually not needed, but they can be removed by freezing them with liquid

nitrogen or by cutting them out. Dermatofibromas are small red to brown bumps that are caused by an accumulation of fibroblasts. They do not require treatment unless they become bothersome or enlarged; then they can be surgically removed. Keratoacanthomas, which resemble squamous cell carcinoma, are round, firm, usually flesh colored growths that have an unusual central crater filled with a pasty material. They can be treated surgically or with injections of corticosteroids or fluorouracil. Keloids are growths of fibrous tissue that form over areas of injury or surgical wounds. Monthly injections of corticosteroids may flatten them somewhat.

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/.
The Genome Project and Keloids In the following section, we will discuss databases and references which relate to the Genome Project and keloids. 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).22 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. 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. 22 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.

Keloids
To search the database, go to http://www.ncbi.nlm.nih.gov/Omim/searchomim.html. Type “keloids” (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 keloids: •

Keloids
To access the Entrez system at the National Center for Biotechnology Information, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?CMD=search&DB=genome, and then select the database that you would like to search. The databases available are listed in the drop box next to “Search.” Enter “keloids” (or synonyms) into the search box and click “Go.” Jablonski’s Multiple Congenital Anomaly/Mental Retardation (MCA/MR) Syndromes Database23 This online resource has been developed to facilitate the identification and differentiation of syndromic entities. Special attention is given to the type of information that is usually limited or completely omitted in existing reference sources due to space limitations of the printed form. At http://www.nlm.nih.gov/mesh/jablonski/syndrome_toc/toc_a.html, you can search across syndromes using an alphabetical index. Search by keywords at http://www.nlm.nih.gov/mesh/jablonski/syndrome_db.html. The Genome Database24 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 “keloids” (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 keloids 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 keloids. 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 keloids. 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 “keloids”:

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 keloids. 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: •
Keloids and Hypertrophic Scars Source: Kirksville, MO: American Osteopathic College of Dermatology (AOCD). 2001. 2 p. Contact: Available online from American Osteopathic College of Dermatology. 1501 East Illinois Street, P.O. Box 7525, Kirksville, MO 63501. (800) 449-2623 or (660) 665-2184. Fax (660) 627-2623. E-mail:
[email protected]. Website: www.aocd.org/skin/dermatologic_diseases/ index.html. Summary: This fact sheet provides people who have keloids and those who have hypertrophic scars with information on the features, symptoms, and treatment of these scars. Keloids are raised, reddish nodules that can develop following a skin injury. They can develop on any part of the body, but the upper chest, shoulders, and upper back are prone to keloid formation. Symptoms include skin pigmentation, itchiness, redness, unusual sensations, and pain. Initial treatment involves injecting long acting cortisone into the keloid once a month. Other treatments include cryosurgery, surgical excision, laser therapy, and x ray therapy. Cryosurgery works well for keloids that are small and occur on lightly pigmented skin. Although laser treatment is very good at improving skin texture and color, it does not always flatten out the keloid. Surgical excision followed by x ray treatments to the site is used for severe cases. Keloids may often be prevented by using a pressure dressing, silicone gel pad, or paper tape over an injury. Recurrences are common, especially among people who have a family history of keloids. Hypertrophic scars, which look similar to keloids, do not get as big as keloids, and they may fade over time. 2 figures.
Patient Resources 101 The NIH Search Utility 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 keloids. 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.

Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “keloids”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “keloids” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “keloids” (or a synonym) into the search box, and click “Submit Query.”

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.25
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

Keloids
lymphoid series (especially plasma cells), or with an antigen closely related to it. [NIH] Antibody: A type of protein made by certain white blood cells in response to a foreign substance (antigen). Each antibody can bind to only a specific antigen. The purpose of this binding is to help destroy the antigen. Antibodies can work in several ways, depending on the nature of the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen. [NIH] Anticoagulant: A drug that helps prevent blood clots from forming. Also called a blood thinner. [NIH] Antigen: Any substance which is capable, under appropriate conditions, of inducing a specific immune response and of reacting with the products of that response, that is, with specific antibody or specifically sensitized T-lymphocytes, or both.

It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA (DNA fragmentation) at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth. [NIH] Aqueous: Having to do with water. [NIH] Arginine: An essential amino acid that is physiologically active in the L-form. [NIH] Argon: A noble gas with the atomic symbol Ar, atomic number 18, and atomic weight 39.948.

Astrocytes (from "star" cells) are irregularly shaped with many long processes, including those with "end feet" which form the glial (limiting) membrane and directly and indirectly contribute to the blood brain barrier. They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with microglia) respond to injury. Astrocytes have high- affinity transmitter uptake systems, voltage-dependent and transmitter-gated ion channels, and can release transmitter, but their role in signaling (as in many other functions) is not well understood. [NIH] Ataxia: Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharnyx, larnyx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or peripheral nerve diseases. Motor ataxia may be associated with cerebellar diseases; cerebral cortex diseases; thalamic diseases; basal ganglia diseases; injury to the red nucleus; and other conditions. [NIH] Atresia: Lack of a normal opening from the esophagus, intestines, or anus. [NIH] Atrium: A chamber; used in anatomical nomenclature to designate a chamber affording entrance to another structure or organ. Usually used alone to designate an atrium of the heart.
