Filter by:The purpose of this study is to evaluate the safety and efficacy of EB01 Cream (0.2%, 1.0%, 2.0%) applied twice per day (BID) for the treatment of moderate to severe chronic allergic contact dermatitis (ACD). The purpose of the open label extension is to assess the long-term safety, tolerability, and efficacy of EB01 2.0% cream in subjects with moderate to severe chronic allergic contact dermatitis.
In-stent restenosis remains one of the most challenging problems in patients after coronary artery angioplasty. Angiographically, it is discovered in 10% of the patients after drug-eluting stent (DES) implantation. There are multiple factors causing restenosis, which can be divided into two major groups: first vessel-dependent (based on the vessel's tortuosity, dimensions and lesion's calcification, all leading to suboptimal stent expansion), and second dependent on the inflammatory processes caused by the intervention. Study objectives is the analysis of the possible correlation between allergy to metals utilised during the stent manufacturing (nickel, cobalt, chromium, molybdenum, tungsten) and in-stent restenosis occurence. The angiographic results of stent implantation, and in-stent restenosis will be assessed independently by two skilled interventional cardiologists, and in case of their discrepant opinions, the decision will be made on the basis of the third cardiologist. The tests will be applicated during the hospitalisation, then read after 48 hours and 72 hours, and subsequently interpreted by the skilled dermatologist, during the hospital stay or afterwards.
The objective of this study is to investigate the potential of NeoMatriXTM Wound Matrix to cause an allergic response to healthy volunteers using a skin prick test.
Repeated insult patch test on healthy males and females to determine potential contact irritation or contact allergy in the skin
This study evaluates the clinical and molecular effect of daily exposure to low doses of the fragrance contact allergen oxidized R-limonene. Three groups of participants are included: 1) Patients with a previous positive patch test to oxidized R-Limonene, 2) patients with a previous doubtful patch test to oxidized R-limonene and 3) healthy controls with no contact allergy to oxidized R-limonene
The former Nickel Directive was introduced in EU in 1994 limiting the release of nickel from items intended for prolonged contact with skin. The nickel regulation entered into full force in 2001 and became a part of REACH (the EU chemicals regulation) in 2009. Since then the prevalence of nickel allergy has declined in some countries, but not in others, following the implementation. Young individuals still become allergic to nickel (2, 3) and a high prevalence of nickel allergy, exceeding 10%, is seen among young women (below 30 years) in the general population. The EU nickel regulation has been changing over time. The present limits of nickel release for metallic items intended for direct and prolonged contact with the skin is <0.5 μg/cm2/week and <0.2 μg/cm2/week for any post assemblies inserted into pierced holes. In 2014, EU defined prolonged contact with the skin as: at least 30 minutes on one or more occasions within two weeks for items with continuous skin contact, or to at least 10 minutes on three or more occasions within two weeks (7). The overall objective is to evaluate how well the EU nickel regulation protects individuals against developing nickel dermatitis. More specifically we will: 1. Study the penetration of nickel in normal and irritated skin after short repeated skin exposure under controlled temperature in nickel sensitized patients and in healthy controls 2. Reveal the potential of short repeated nickel skin exposure on normal and irritated skin to elicit dermatitis, during controlled climate factors in nickel sensitized patients and controls using the time restrictions of the definition of prolonged skin contact in the nickel regulation.
The primary objectives of this study are to identify positivity rates to three novel surfactants (ingredients used in soaps, detergents, and other cleansers that serve to lower the surface tension of the skin and remove debris) and co-reactivity with other surfactants in patients with known surfactant sensitivity on skin patch testing. The investigators hypothesize that subjects who previously tested positive to known allergenic surfactants (cocamidopropyl betaine, stearamidopropyl dimethylamine, dimethylaminopropylamine, coconut diethanolamide, oleamidopropyl dimethylamine, and decyl glucoside) may demonstrate co-reactivity to the three novel surfactant sensitizers (sodium lauroyl sarcosinate, isostearmidopropyl morpholine lactate, and disodium lauroamphodiacetate) on skin patch testing.
The purpose of this study is to evaluate if metal patch testing in metal allergic patients is useful for predicting the development of allergic skin disease or systemic symptoms in patients who recieve a metal orthopedic implant.
The purpose of this study is to determine whether extended information given to patients with contact allergy improves knowledge, treatment efficacy and daily functioning.
The purpose of this study is to compare the allergen ethylenediamine dihydrochloride when prepared using methylcellulose versus preparation using polyvinylpyrrolidone.
