Skin protects the body from the environment and is an important component of the innate and adaptive immune systems. Atopic dermatitis and contact dermatitis are among the most frequent inflammatory skin diseases and are both determined by multigenic predisposition, environmental factors, and aberrant immune response. Peptidoglycan Recognition Proteins (Pglyrps) are expressed in the skin and we...

Many factors may aggravate atopic dermatitis. The aim of this study was to determine the frequency of atopic dermatitis in an unselected population sample and to evaluate the role of food allergy. Patients with atopic dermatitis were recruited from the population in Berlin, Germany, using a postal questionnaire. Skin prick tests for allergens were performed, followed by food challenges. A total...

Pruni cortex, the bark of Prunus jamasakura Siebold ex Koidzumi, has been used in the Japanese systems of medicine for many years for its anti-inflammatory, antioxidant and antitussive properties. In this study, we investigated the effect of pruni cortex on atopic dermatitis NC/Nga mouse model. Atopic dermatitis-like lesion was induced by the application of house dust mite extract to the dorsal...

Metal allergies can be a clinical problem, especially in atopic individuals. This study is unique and contributes with new knowledge in everyday life skin care of irritant and atopic dermatitis patients. The aim of the study was to determine the frequency of positive patch test reactions to metal contact allergens (potassium dichromate, cobalt chloride, nickel sulfate, white mercury precipitate...

BACKGROUND Health care workers (HCWs) are at increased risk of irritant contact dermatitis due to frequent hand washing and use of alcohol gel. This has increased the incidence of occupational skin diseases. AIMS To evaluate hand dermatitis in HCWs in our hospital by means of a survey which also examined trends of exposure and the utility of patch testing. METHODS HCWs diagnosed with hand d...

Introduction: Exfoliative dermatitis is an extreme state of skin irritation resulting in extensive erythema and or scaling of the body. More than 90% of skin surface involvement is considered as a salient pre-requisite to make a clinical diagnosis of exfoliative dermatitis. Histopathology aids in the diagnosis of many cases of exfoliative dermatitis. Purpose: Exfoliative dermatitis can be cause...

This study investigated the relationship between level of stress in middle and high school students aged 12-18 and risk of atopic dermatitis. Data from the Sixth Korea Youth Risk Behavior Web-based Survey (KYRBWS-VI), a cross-sectional study among 74,980 students in 800 middle schools and high schools with a response rate of 97.7%, were analyzed. Ordinal logistic regression analyses were conduc...

Skin disorders comprise more than 35% of all occupationally related diseases. 90-95% of work-related dermatoses are contact dermatitis. Effects of occupational dermatitis in the lives of workers are substantial. To plan any preventive program we need basic statistics of the problem, that we had no reliable one which includes a lot of industries in Iran. Therefore we decided to determine occupat...

Infection from Toxocara species may give rise to a large array of clinical symptoms, including apparent manifestations of allergy such as asthma, urticaria/angioedema, and dermatitis. We report a case, thus far not described, of contact dermatitis attributed to nickel allergy but caused by Toxocara infection. The patient was a 53-year-old woman presenting from 10 years a dermatitis affecting he...

The endogenous estrogens are important modulators of the immune system and its functions. However, their effects are rather complex and many aspects have not been studied. In this study, we used the 1-chloro-2,4-dinitrobenzene (DNCB)-induced contact dermatitis as a disease model and investigated the effect of estriol (E3), along with two other estrogens, 17β-estradiol and estrone, on the pathog...
