Filter by:Contact dermatitis (CD) is a common inflammatory skin disease, affecting approximately 15-20% of the general population in industrialized countries and ranking first among occupational diseases in many European countries. The patch test method aims at reproducing the eczematous lesions by applying occlusive patches containing the suspected allergens to the patient's healthy skin. It requires experienced medical staff to read the reaction. Newtones Technologies society has developed a new tool, the SkinCam®, able to capture high resolution cross and parallel images, allowing a quantification of color and relief of skin. This study aims to illustrate patch test results, describing skin appearance (color, roughness, shine), using photographs taken by the SkinCam®.
Linalool is currently one of the most used fragrance substances in cosmetic and household products. Previous studies report a high prevalence (5.9-11.7%) of contact allergy to hydroperoxides of linalool (Lin-OOH)1.0% in pet. among patch tested patients. The optimal test concentration of Lin-OOH in patch tests is not known and requires further investigation. It is of great importance to establish the optimal test concentration and elicitation threshold of Lin-OOH to improve diagnosis and prevent development of Allergic Contact Dermatitis (ACD). We want to mimic real-life exposure to Lin-OOH, by conducting a ROAT (Repeated Open Application Test) study, on 40 adult participants (20 patients with confirmed contact allergy to Lin-OOH, and 20 healthy participants) to low doses of Lin-OOH using a simulated "perfume", during a maximum of 21 days of exposure. With this knowledge, we aim to: 1. Establish the optimal patch test concentration to diagnose ACD to Lin-OOH 2. In case of confirmed contact allergy, examine the threshold value for the development of ACD upon daily exposure to a simulated leave-on cosmetic product
The study will investigate if Anakinra can ameliorate allergic contact dermatitis in participants with known nickel allergy
This is a randomized, double-blind, placebo-controlled, single ascending dose study to assess the safety and tolerability of PDC-APB by intramuscular (IM) injection compared to placebo.
We intend to evaluate the efficiency and tolerability of a barrier cream (bariederm) in protecting hands of individuals with hand dermatitis, either due to allergy or irritation. We believe that the use of the cream would benefit with the skin.
The purpose of the study is to determine if any of Mother's Choice' all-natural personal-care products cause either irritation or allergic reaction when applied to both normal or sensitive skin. Each product will be tested on the skin using patch tests.
Nickel contact dermatitis (eczema) is one of the most common allergic conditions affecting the skin. This is a study looking at potentially desensitizing nickel-allergic patients to their allergy using anti-inflammatory ointments applied to the skin (arm). Application of these ointments (ie. modified Vitamin D) has been shown to increase specific immune cells (T regulatory cells), which play a role in preventing immune activation and subsequently inflammation. The investigators propose use of topical anti-inflammatory agents (corticosteroids, modified Vitamin D, or both) may desensitize patients with nickel allergy.
Topical corticosteroids are largely used in dermatology. The major problem related to their use is that the same mechanisms underlying their therapeutic effects (antiinflammatory and antiproliferative) may lead to adverse events. Conditions sensitive to corticosteroids require formulations with mild to moderate potency while high-potency corticosteroids era required in less responsive conditions. The aim of the present study is to compare the safety and efficacy of prednisolone acetate 0.5% cream (mild-potency non-fluoridated corticosteroid) versus betamethasone valerate 0.1% cream (high-potency fluoridated corticosteroid) in the treatment of mild to moderate cortisosensitive dermatosis (atopic dermatitis, contact dermatitis, seborrheic dermatitis and psoriasis). The study hypothesis is that 0.5% prednisolone cream will be as effective as 0.1% betamethasone cream and will be an alternative option to treat corticosensitive dermatosis in body areas where the use of fluoridated corticosteroids is contraindicated, such as the face.
The study is required by the FDA as part of a post-marketing commitment. The purpose of the study is to compare the reactivity of the TRUE Test quaternium-15 patch and a real use exposure.The subjects will wear the patch test for 48 hours and reading will be performed day 3 or 4. The use test will be applied from day 3 or 4 and untill reaction appears. Reactions from respectively TRUE Test and use test will be compared using the McNemar Change Test.
