In 2013, we raised suspicion that cobalt in leather could be responsible for hitherto unrecognized cases of allergic contact dermatitis. We saw a patient sensitized only to cobalt with clear long-term exposure to cobalt from a leather sofa, and observed resolution of dermatitis following avoidance (1). In 2014,we performed a questionnaire study, which showed a positive and significant associati...

Allergic contact dermatitis to cement is a delayed-type hypersensitivity reaction in which cytokines interferon-gamma (IEN-y) and vascular endothelial growth factor(VEGF) may be involved in persisting erythema and oedema. VEGF and IFN-gamma levels in serum and skin lesions were measured in 32 Egyptian building workers with chronic allergic contact dermatitis due to occupational exposure to ceme...

Background/objective: Facial dermatitis is common and the roles different exogenous factors play between facial and nonfacial dermatitis is unknown. The study aim was to investigate the etiology and selfreported exogenous aggravation factors in facial dermatitis. Methods: There were 89 facial dermatitis patients patch tested in a tertiary hospital during a 1-year period, and 112 patients with n...

Over the past years, hydrocolloid dressings have been introduced routinely in the treatment of various types of wounds. They provide a moist environment promoting autolytic debridement, and stimulate angiogenesis. However, long-term application often leads to inflammation of the skin in the immediate area of the ulcer, causing irritant dermatitis in many cases, but sometimes also leads to conta...

Background: Interleukin (IL) 33, a novel member of the IL-1 family, is produced mainly by epithelial cells and endothelial cells in response to various types of stress, including necrosis. The effects of IL-33 on the immune cells involved in allergic contact dermatitis have recently been revealed in vitro. However, in vivo, the induction mechanism and function of IL-33 are not fully understood....

BACKGROUND Atopic dermatitis (AD) is a chronically relapsing dermatitis with no known cure. Due to the chronic nature of the condition, frequent and long term topical therapy is used. This may lead to sensitization, resulting in allergic contact dermatitis (ACD). AIMS The aim of the study was to observe the frequency of ACD in atopic patients in this part of the country using Indian standard ...

BACKGROUND Hairdressers are at risk of developing occupational contact dermatitis because of their intense contact with wet work in combination with chemicals. OBJECTIVES To perform an analysis of a cohort study of hairdressers with occupational contact dermatitis recognized in the period 2006-2011, focusing on individual and environmental factors associated with the disease. METHODS The st...

Compresses containing a nonsteroidal antiinflammatory drug (NSAID) are commonly used in Japan. However, this treatment may induce both allergic and photoallergic contact dermatitis from the NSAIDs and their ingredients. Here, we describe a case of allergic contact dermatitis with diffuse erythematous reaction due to diisopropanolamine in the applied compress. The absorption of diisopropanolamin...
