Active clinical trials for "Dermatitis"

Irritant contact dermatitis induced by sodium lauryl sulphate (SLS) is often used as a model for testing efficacy of various topical preparations. Aforementioned model is standardized and described in guidelines, but it is not explicitly stated where the irritation should be induced. Published clinical trials usually irritate volar aspect of forearms or upper back. Also, lower back and dorsal aspect of forearm are sometimes used. Skin parameters vary depending on anatomic location of measured skin. There is a difference in stratum corneum thickness, hydration and transepidermal water loss across different locations, including between volar forearm and upper back. Furthermore, regional difference in skin response to irritation by tape stripping and benzalkonium chloride were observed. Such differences are also possible in SLS irritation model. One study has shown higher, but not statistically significant, response of back in comparison to forearms, but it had a very small sample size (n=9). Moreover, there are regional variations of topical preparations absorption. Hydrocortisone had 1,7 times higher absorption when applied to upper back in comparison to forearms. Those variations could be explained by different corneocyte size and number of their layers between back and hands. Skin baseline properties and response to irritation seem to be dependent on anatomic position. Those differences could mean different response to treatment. Since published trials only tested efficacy of various preparations on one anatomic location, it is possible their results would be different if tested on other body parts. It could limit validity and usefulness of conducted trials. The aim of this study is to determine if there are regional differences of skin response to irritation and emollient cream treatment in irritant contact dermatitis model.

The purpose of this study is to evaluate in a randomized, double-blinded, controlled trial, whether a new food supplement containing Lactobacillus reuteri DSM 17938 and vitamin D3 (Reuterin® D3) may improve the SCORAD in pediatric patients with mild to moderate atopic dermatitis

The aim of this study is to compare the efficacy and tolerability of a cosmetic product to one that is already available on the market (benchmark product). Efficacy is assessed by instrumental measurements of skin condition, clinical examinations, and questionnaires.

The purpose of the study is to assess the effect of a single dose of NI-0801 on the severity of nickel-induced allergic contact dermatitis.

The principal aim of this study is to obtain safety, tolerability and pharmacokinetic data when LEO 29102 is administered cutaneously as single and multiple doses to healthy subjects. The study is divided into one single dose part, one part to compare pharmacokinetics between gender and one multiple dose part.

The number of infants and children with allergic disease (dermatitis, allergies, asthma) has increased over the last several decades. This may be related to changes in diet. It is now thought that children become sensitised to allergens very early in life maybe even before they are born. Some studies show that a high omega-3 fat intake by mothers decreases risk of sensitisation in their babies. There is a biological mechanism to explain this. Omega-3 fats are found in oily fish like salmon. In the UK pregnant women are recommended to eat oily fish twice per week. However, consumption of oily fish is known to be low in pregnant women in the UK. This study sets out to identify the effects of increasing salmon intake in pregnant women. The hypothesis being investigated is that : increased consumption of oily fish during pregnancy by women at risk of having offspring who will develop atopy will increase their omega-3 fat and antioxidant status and that of their developing baby and will ameliorate the development of atopic markers and manifestations in the infants.

Natural Killer (NK) cells play a unique role during innate immune responses as they are able to recognize and eliminate, without specific sensitization, tumors, microbe-infected cells as well as allogeneic cells.In a first time, we will characterize the tissue distribution, the phenotype and the effector functions of NK cells present in the human healthy skin.

The purpose of this study is to compare the effect of video-based patient education with written instruction on subjects' knowledge of atopic dermatitis and their disease severity, measured by the Patient-oriented Eczema Measure (POEM), after viewing the educational materials.

Radiation dermatitis is a common side-effect of radiation therapy in cancer patients who frequently can experience redness, pain, crusting, and even ulceration of the skin causing suffering and treatment interruption. A recent retrospective study by DeLand demonstrated that administering light emitting diode (LED) photomodulation after each radiation treatment for breast cancer decreased radiation dermatitis in a majority of patients. LED photomodulation is a process by which specific sequences of light are used to regulate or manipulate cell activity without causing heat or damage to the skin. Each LED treatment is painless and is completed in usually less than one minute. LED photomodulation may reduce the suffering associated with radiation treatments, improve cosmetic outcome in radiation fields, and eliminate breaks in radiation treatments which may be required because of severe ulcerating reactions. This study will attempt to replicate the findings of Dr. DeLand's study by randomly assigning at least 40 breast cancer patients to either a treatment group or to a control group. The treatment group will receive LED photomodulation treatments before and after each radiation treatment with the Gentlewaves Select™ handheld high energy 590nm LED array using specific sequences of pulses used in other studies; the treatment group will also receive 7 additional treatments over 2 weeks after their radiation treatment course is completed. The control group will receive no LED treatment but will use the exact same skin care regimen as the treatment group. In addition to weekly evaluation and grading of skin reactions, subjects will be photographed under standardized conditions weekly and then photographs will be evaluated and graded by blinded dermatologists.

The main objective of the Atopic Dermatitis and Vaccinia Immunization Network (ADVN) is to reduce the risk of the fatal reaction, eczema vaccinatum (EV), to the smallpox vaccination in those with atopic dermatitis (AD). Since vaccination with live vaccinia virus (VV) in individuals with AD increases the risk of EV, a yellow fever vaccine was chosen. The purpose of this study is to determine the immune response to a yellow fever vaccine in adults with AD.
