Filter by:This study is a randomized, double-blind, placebo-controlled bilateral study on the effect of moisturizing creams on skin barrier function. The hypothesis is that a new active emulsion has a better influence on skin barrier function comapred to its placebo.
This study will examine microbes (e.g., bacteria, fungi, viruses) that live on human skin and how microbes contribute to health and disease. It will analyze healthy human skin and how the these microorganisms might change in patients with atopic dermatitis (AD), a skin condition also known as eczema. Healthy volunteers, as well as patients with moderate to severe eczema (AD), between 2 and 40 years of age may be eligible for this study. We also wish to enroll children and adults aged 2-40 who have been diagnosed with inherited immune disorders known as HIES (hyperimmunoglobulin-E syndrome), WAS (Wiskott-Aldrich syndrome), or DOCK8 immunodeficiency because they frequently have skin problems similar to AD. Eligible participants undergo the following tests and procedures: - Medical family and medication history - Skin examination - Blood tests (research blood as well as serum IgE, and complete blood count) - Skin samples to analyze microbes. Samples are obtained by the following methods: swabbing the skin with a cotton swab; scraping (scratching) the skin gently with a blade to remove only the outermost skin layers; and, only in adults, biopsy (surgical removal) of a small skin sample less than 1/4-inch (5 mm) in diameter. - Nose swabs to analyze microbes. - Patients with eczema may have photographs of their skin taken to help monitor the skin rashes. Participants may be contacted periodically for follow-up studies. Patients with atopic dermatitis may have additional skin samples collected to examine changes in the skin bacteria over time and during all of the stages of eczema. In addition, patients who have a flare of their eczema are asked to undergo a skin sample collection as soon as possible.
This study will examine the risk of systemic malignancies in pediatric patients with atopic dermatitis exposed to Elidel 1% cream.
The current knowledge of the pathophysiology of allergic contact dermatitis is based on the murine model. In this model, CD8+ T cells are effector cells, and CD4+ T cells regulate the response by limiting the expansion of CD8+ T cells. The goal of this study is to characterize the pathophysiology of contact dermatitis, with patients allergic to para-phenylenediamine (PPD). We suppose that the CD8+ T cells are the effectors of the allergic contact dermatitis, although the regulator cells belong to the LT CD4+ population. We will test our hypothesis on blood samples, and cutaneous biopsies of patients allergic to PPD.
This is a tissue, urine, and blood banking protocol for cutaneous t-cell lymphoma (CTCL), eczema, and atopic dermatitis patients for current and future research.
To analyze the common allergens revealed by skin tests in adult atopic dermatitis patients.
