Abstract
Of 124 patients with eczema and dermatitis patch tested by the European standard series of allergens in the period from April to October 1989, 59 cases showed sensitivity to 1 or more allergens. Potassium dichromate, nickel sulphate and cobalt chloride were the 3 major sensitizers, with a frequency of 17.9%, 13.8% and 10.6%, respectively. The office and factory workers showed a higher incidence of positive reactions than the student group. The environment of the office and the factory seems to be the potential source of exacerbating factors of eczematous skin disease.Keywords
