[Occupational asthma and dermatitis after exposure to dusts of persulfate salts in two industrial workers (author's transl)].
Two workers developed dermatitis, rhinitis, bronchitis, and asthma after occupational exposure to dusts of persulfate salts. The causative role of the persulfate salts could be confirmed by case history, skin tests, occupational exposure tests and by removal of the 2 workers from their jobs. Patch tests produced late cutaneous reactions. Occupational exposure at the working place for 8 h resulted in each case in a pathological increase of airway resistance. Withdrawal from occupational exposure to persulfate salts resulted in recovery within a few days. Our results suggest that chemically irritative or toxic effects of persulfate salts play the predominant role in the pathogenesis of the reported cases.

[Contact urticaria].
Report of a 42 year old woman who had given up her profession as a hairdresser because of urticarial skin eruptions following contact with substances used during working. An open patch test showed after 30 min positive urticarial reactions against permanent wave solution, fixation solution, p-aminodiphenylamin, lanolin-alcohol and clioquinol.

[Allergy diagnosis in patients with bronchial asthma (bronchial provocation test, skin test and RAST) (author's transl)].
87 patients with bronchial asthma underwent skin test, RAST and measurment of airway resistance before and after inhalation of control solution as well as at least 10 times after each of one to four bronchial provocations (making up a total of 171 tests) with extracts of house dust, house dust mite, animal dander, mould spores and pollen in increasing concentrations. An actual clinical significance of the skin test reactions was found in 60% of all cases and of the RAST results in 66% of all cases. The overall agreement between skin test results and RAST results was 61%. The correlations between the different tests depended on the degree of hypersensitivity, on the tested allergen and on whether the results of skin test and RAST, respectively, were positive or negative. There existed a good correlation between the results of all three test methods and case history only for pollen allergens and animal dander. Noticeably often negative RAST results with house dust and mould spores, as well as positive skin tests with house dust mite and mould spores could not be confirmed by the provocation test. Important indications for a bronchial provocation test in asthmatics are doubtful case history, doubtful skin test or RAST results with the problem-allergens house dust, house dust mite and mould spores; the bronchial provocation test is especially commendable when drastic or cumbersome therapeutic measures (immunotherapy, change of home, change of job) are to follow or if late asthmatic reactions are expected.

[Zinc treatment of acrodermatitis enteropathica (author's transl)].
Treatment of acrodermatitis enteropathica with zinc sulfate, first described by Moynahan and Barnes in 1973, has been widely accepted. We have treated a case of acrodermatitis enteropathica successfully with this drug. The 14-year old boy had to discontinue clioquinol because of a partial opticus atrophy. The skin lesions deteriorated acutely. Following zinc sulfate treatment the lesions rapidly disappeared and the general health of the patient greatly improved. Small doses of zinc sulfate are sufficient for maintenance therapy. The pathogenesis of acrodermatitis enteropathica is reviewed and the modes of action of zinc therapy are considered.
