Abstract: Occupational dermatitis (irritant dermatitis, contact urticaria and contact eczema) is frequent among healthcare workers. Irritant hand dermatitis, the most common occupational dermatitis, occurs often in individual who work in a humid environment, who handle disinfectants, and who are required to wash their hands frequently; atopic dermatitis is a risk factor for this condition. Natural rubber latex present in rubber gloves is the most common cause of contact urticaria. Contact eczema can be induced by rubber accelerators (for example, thiurams) present in gloves, and also by disinfectants (glutaraldehyde, dodecyldimethylammonium), disinfectants and detergents, hand creams, acrylates (in dentists), and echography gels. Nurses sometimes develop contact dermatitis to drugs they handle; these allergies should be diagnosed by appropriate skin testing because sensitized individuals may develop a severe, generalized cutaneous adverse reaction if they are subsequently exposed systemically to the sensitizing drug.
