title: [Occurrence of nickel contact allergy in randomly selected patients in the Munich area].
abstract: A group of 503 persons having no current dermatitis was examined by questionnaire and a patch test with 2.5% and 5% NiSO4 in petrolatum. Among these, 4.77% (62.5% aged up to 39 years) showed a positive reaction, affecting 1.64% of the tested males and 7.72% of the tested females. Grouped by profession, medical personnel yielded the highest percentage of positive reactions (12%), and workers who had frequent occupational contact to nickel showed more positive reactions than workers who had no occupational contact to nickel. Among persons having a history of allergy to nickel, 51.7% yielded positive reactions; and 62.5% of those yielding positive reactions had a corresponding case history. The two test concentrations (2.5% and 5%) caused essentially the same reactions.
