[Occupational skin allergies in 1993-1998]

There are few data on the frequency of occupational allergic dermatitis in the context of occupational diseases and there is a need for coordinated large-scale studies to compare the experiences of different Occupational Health Departments involved in the surveillance of allergic occupational diseases. Therefore 6 Occupational Health Departments of Northern Italy (Bergamo, Brescia, Cremona, Desio, Lecco and Milano-CEMOC) decided to bring together all the cases of occupational allergic dermatitis diagnosed between 1993 and 1998. In this report the main characteristics of these 961 allergic dermatitis (888 allergic contact dermatitis, 63 urticaria and 10 airborne contact dermatitis), the possible correlations with gender, age, length of employment, atopy and the occupations at high risk of acquiring allergic dermatitis have been described.
