Active clinical trials for "Skin Diseases"

Determining Fitzpatrick skin phototypes (FST) allows physicians to assess a person's risk of developing sunburn, and thus the need for sun protection to prevent the development of skin cancer. Reflectance spectrophotometry objectively measures the melanin index (MI) and can assist in determining the accuracy of self-reported FST compared with dermatologist-determined FST. At present, we seek to determine the accuracy of an adapted Skin Sun Sensitivity Scale for individuals of all pigmentation varieties (FST I through VI) as compared with spectrophotometric measurements assessing FST. Our principal objective is to correlate the MI under usual conditions by spectrophotometry with the adapted Fitzpatrick SPT as determined by the patients' responses to the adapted questionnaire.

This study is a single-site trial assessing the specificity of CL Detect™ Rapid Test versus the gold standard for Leishmania diagnosis in the US which is microscopic identification of Leishmania amastigotes in a stained lesion sample. Subjects will be patients who present for dermatology consultation with a primarily ulcerated lesion. After informed consent is obtained and the subject is screened for eligibility, 2 diagnostic samples will be collected from the subject's lesion in the following order: 1) one sample will be obtained with a dental broach for use with the CL Detect™ Rapid Test and 2) a second sample will be obtained by scraping for use in the microscopic identification of amastigotes. Samples will be analyzed by microscopy and CL Detect™ Rapid Test. The CL Detect™ Rapid Test will be performed by different operators who are clinical staff members. These staff members, blinded to each other's results, will evaluate the samples from each method independently. Each of the 150 study subjects will be followed administratively to the point where a diagnosis is established (if possible) for their tested lesion, even if that diagnosis is not cutaneous leishmaniasis (CL). If a specific diagnosis cannot be determined for a non-CL lesion, the investigator will assign a "likely etiology" (eg, infectious, oncological, immunological, vascular, or "undetermined/other" origin). Based on the diagnosis determined for each lesion, subjects will be referred for appropriate treatment.

The purpose of this study is to image skin and skin lesions with a new imaging technology called "multiwavelength and coherence confocal reflectance microscopy". This technology uses low intensity laser to image below the surface of the skin. This technology may provide a new way of looking at skin and skin lesions. The goal of this study is to evaluate the images of your skin taken by this microscope. The techniques being evaluated in this study use multi wavelength and coherence confocal reflectance microscopy invivo. The term "in vivo" means in/on a living subject. In this study you will be the living subject and the multi wave length and coherence confocal microscope will be placed on your skin to look at your skin lesions and your normal skin. The confocal microscope uses a weak laser light and a sophisticated lens to image the individual cells that make up the skin. Your lesion will be photographed with high resolution photography. An area near your skin lesion that is clinically normal will also be imaged in the same manner.

This study will examine the structure of the receptor molecule for the herpes simplex virus (HSV) and determine if the receptor's structure is related to susceptibility to infection with the virus. There are two types of herpes virus-HSV-1 and HSV-2. HSV-1 commonly causes cold sores, and HSV-2 usually causes genital herpes. The herpes virus enters (infects) cells through protein molecules on the cell's surface. This study will explore possible differences between the structure of the HSV receptor molecule in different people to understand better how infection occurs. The study will also look at proteins on white blood cells (Fc receptors, cytokines and mannose binding protein) that may influence the risk of infection with HSV. Information from this study may lead to new treatments to prevent HSV infection. People 18 years of age and older who are infected with HSV and people who are not infected with the virus may be eligible for this study. Participants will have blood drawn to confirm whether or not they have been infected with the virus. The blood sample will also be used to study the genes for the HSV receptor, Fc receptors, cytokines, mannose binding protein and related proteins on the white blood cells. No more than 40 milliliters (8 teaspoons) of blood will be drawn. Participants who are found to have antibodies to HSV-2 will be offered counseling and advice on practicing safe sex techniques to help prevent sexually transmitted diseases, including HSV-2 infection.

Autoimmune bullous dermatoses are a group of diseases with chronic course. They are provoked by the production of autoantibodies against the dermal-epidermal junction or against the inter-keratinocyte junctions, resulting in the formation of intra-epidermal or sub-epidermal blisters. The diagnosis of autoimmune bullous dermatoses is based on clinical and immunopathological findings, including skin direct immunofluorescence. Systemic corticosteroid therapy is generally considered as the mainstay of treatment for many years both for bullous pemphigoid and pemphigus which are the most frequent diseases.

The participants presenting with hand problems and meeting the inclusion criteria are asked to apply the study product for one month. They are evaluated before and after treatment.

Comparison of online question-answering system and conventional consultation for dermatological questions: same diagnosis? same information, which had been collected? same recommendations about treatment? what were the relevant differences of the two?

The purpose of this study is to investigate the prevalence of depression, anxiety, and sleep problems in patients with chronic skin diseases in dermatology clinics at the University of Wisconsin Hospital and Clinics.

Objective: This study aimed to evaluate and compare the periodontal status of chronic skin disease (CSD) patients with healthy controls. Material and method: 109 patients and 37 healthy subjects were included in this study. Parameters evaluated included bleeding on probing index (BOP), periodontal pocket depths (PPD), clinical attachment level (CAL), simplified debris index (DI), simplified calculus index (CI), and the presence of oral lesions. Clinical parameters were measured and compared in the two groups. The significant level was set at 0.05.

Erosive pustular dermatosis of the leg is a fairlyrecent clinical entity that was described the first time in 1987. Diagnosis of erosive pustular dermatosis of the leg is made on clinical grounds. It presents as non-follicular pustules of variable size and numbers that rapidly give way to erosions and crusts on one or both legs, and which are found in particular on the anterior aspect of the middle third of the leg (. The lesions are of chronic progression, despite topical therapy. Erosive pustular dermatosis of the leg is seen in elderly patients, mainly female, and may be associated with chronic venous insufficiency or cutaneous atrophy. In the absence of specific criteria and because of the existence of misleading clinical forms, diagnosis is based upon exclusion.
