This is one of series of review articles on formaldehyde and formaldehyde-releasers (others: formaldehyde in cosmetics, in clothes and in metalworking fluids and miscellaneous). Thirty-five chemicals were identified as being formaldehyde-releasers. Although a further seven are listed in the literature as formaldehyde-releasers, data are inadequate to consider them as such beyond doubt. Several ...

Artificial photobonded acrylic gel nails, used to improve the cosmetic appearance of natural nails, have gained popularity over recent years. They can cause allergic contact dermatitis both in occupational and in non-occupational settings. It affects not only the nail area but also the elsewhere on the hands, and occasionally involves the face, including the eyelids, mainly due to an occupation...

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: Contact dermatitis to cosmetics is a common dermatosis, especially in adults and professionals who handle them. OBJECTIVE: The objective of this study was to evaluate the frequency of sensitization to cosmetics ́ components in patients with suspected allergic contact dermatitis and to identify the main sensitizers related to occupational contact dermatitis. METHODS: During the period...

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....
