[Industrial dermatoses among the Bełthatów brown coal miners]

443 subjects were examined, 235 applying to the physician due to the occurrence of skin dermatoses (group I) and 208 workers referred for periodic examinations (group II). In group I skin dermatoses were found in 100, i.e. 85%, of the subjects and in group II in 99 i.e. 48% of the subjects. In both groups the most frequent dermatosis was feet skin inflammation, especially interdigital intertrigo. Oil acne was diagnosed in 15, ordinary acne in 23, pityriasis versicolor in 19. erythrasma in 10, and eczema and contact dermatitis in 7 subjects of the first group and 3 subjects of the other group. 204 subjects with feet skin pathologies underwent mycologic examinations and 36 subjects--also bacteriologic examinations. The results of those studies indicate that in 23% of the subjects, feet interdigital intertrigo results from mycologic infections. Bacterial infections may contribute to etiopathogenesis. Imidazole compounds are useful for the treatment and prevention of interdigital intertrigo.
