We are not doctors. Always consult your mD about Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles Clinical research trials and Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles medical trials take place in many of places throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectiveness of new does drugs. The purpose of the studies / projects is to solve specific human healthcare questions. Clinical trials are a popular way for mDs, government agencies, and private sector companies to find cures for all varieties of conditions, like Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles. Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles Clinical Trials and other clinical trials allow for volunteers to have health treatment options before they are available to the masses. Many times the human subjects acquire professional assistance for free of charge, and sometimes they are compensated for their time. Occasionally there is a cost for a Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles clinical trial. Test subjects typically obtain the finest healthcare available for their Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles condition. Dangers are a reality, nevertheless, and might include additional or frequent doctor trips, medical dangers (possibly life-jeopardising), and/or the treatment being ineffectual. Trials are federally regulated with strict guidelines to protect clinical trials patients.

Assessment of Digital Imaging as a Tool for Diagnosing Psoriasis, Hand Rashes and Unusual Moles
For Condition: dermatitis,psoriasis,nevus
Status: Completed
Sponsor(s): National Cancer Institute (NCI) ,
Synopsis: This study will evaluate whether digital photography is a reliable tool for diagnosing hand rashes, psoriasis and unusual moles. The findings will help determine if this method can be used in the National Health and Nutrition Examination survey (NHANES), which monitors disease in the United States. Employees of the National Institutes of Health 19 years and older may enroll in this study. Participants will complete a brief questionnaire that includes information on skin type, history of skin conditions (moles, cancer, rashes, psoriasis), and demographic information such as name, age and sex. They will be examined by a dermatologist, who will note in writing the appearance of any hand rashes, unusual moles, or psoriasis. If any areas suspicious for skin cancer are found, the participant will receive this information in writing, along with advice about where to go for treatment. A total of six photographs will then be taken of the participant's arms, legs, hands and back. The face will not be photographed, and the participants will not be identifiable.
Details: This validation study is designed to evaluate the sensitivity, specificity, validity and reliability of digital photography of the skin as a prevalence assessment tool in preparation for the National Health and Nutrition Examination Survey, 2001 (NHANES IV). NHANES is charged with monitoring disease in the U.S. population, which is affected frequently by skin disorders and disease. The three skin disorders proposed for study in NHANES IV are atypical nevi, psoriasis, and hand dermatitis. This selection is based on the expected impact of these diseases on the U.S. population, including a prevalence of 3-10%, associated risk of melanoma in the case of atypical nevi, and associated disability in the cases of psoriasis and hand dermatitis. This skin disease section of NHANES, as currently planned for 2001, includes an imaging component with four standardized photographs to be obtained from each survey participant (SP). The selection of the regions to be photographed is designed to maximize the information obtained, while preserving patient privacy and is based on the known distribution of clinical findings of the three conditions, as well as NHANES logistical limitations. This validation study is a cooperative effort between the NIAMS extramural programs, the NCI intramural program, and the National Center for Health Statistics.
Eligibility:
Study Type: Observational, Natural History
Minimum Age/Maximum Age: /
Genders: Both
Protocol Entry Criteria: Must have employee status at the National Institutes of Health. Age greater than 18 years. Able to understand and sign consent. Patients who are wheelchair bound and are unable to have images of their back and lower extremities taken safely will be excluded from photography since this portion of the examination requires an ability to stand. However, they will still be eligible to participate in the skin cancer screening.
