[Irritant effect of tensides on occupational dermatitis patients in hairdressing and nursing occupations. Comparative studies of healthy persons and neurodermatitis patients].

The irritational disposition of the skin was studied in a control group of 12 healthy persons, 8 patients with neurodermitis, 11 hairdressers with occupational dermatitis and 11 nurses with occupational dermatitis by using the Duhring-chamber-scarification test. For comparison, the alkali resistance test was also carried out. The results show that with the alkali resistance test the irritational disposition towards tensides may not be judged. The present findings show that the increased irritational disposition toward detergent substances seems to be a constitutional factor which favors the development of occupational dermatitis in hairdressing and nursing jobs; with the patient suffering from atopic dermatitis, one must presume an increased irritational disposition towards tensides in most cases.

Occupational dermatitis from Lactuca sativa (lettuce) and Cichorium (endive). Simultaneous occurrence of immediate and delayed allergy as a cause of contact dermatitis.

Four patients with occupational contact dermatitis to Lactuca sativa had cross-sensitivity to Cichorium endivia. One of the patients also had contact urticaria to Lactuca and Cichorium, and another reacted positively to scratch tests with these plants as a sign of immediate allergy. In two cases such immediate allergy was considered the cause of a vesicular, intense itching eruption within a few minutes of contact with fresh leaves of Lactuca on previously eczematous skin. The severe chronic dermatitis of the hands of these patients is ascribed to combined delayed and immediate allergy.

Adult

Prolonged and recurrent occupational dermatitis. Some whys and wherefores.

Most cases of occupational dermatitis are successfully diagnosed and treated effectively; with proper preventive measures, the patient can resume work. This is not always the case, however, because there are certain employees whose dermatitis defies the best diagnostic and therapeutic measures. Such cases engender disagreement between the patient and physician, the employer, the insurance carrier, and the compensation commission. Several of the causes for failure to effect a cure in cases of occupational dermatitis are explained in this article.

Chronic Disease

Occupational dermatitis in a prefabrication construction factory.

In a field study of occupational dermatoses in a prefabrication construction factory, 272 workers were interviewed, examined and patch tested to chromate, cobalt, nickel, rubber mixes, epoxy resin, melamine formaldehyde and conplasts. The prevalence of occupational dermatitis was 14% (38/272); 57% (22/38) were irritant dermatitis from cement; 39.5% (15/38) were allergic contact dermatitis from cement (2 with concomitant rubber glove allergy); and 2.5% (1/38) were allergic to rubber chemicals in gloves. The overall prevalence of chromate sensitivity was 8.5% (23/272), with the highest rate from the concreting bays of the factory. The rate was unrelated to the duration of workers' engagement in construction work. 34.8% (8/23) had asymptomatic chromate allergy. The prevalence of cobalt reactions was 17.4% (4/23) and all were associated with chromate allergy.

Adolescent

Occupational dermatitis from dibutyl maleinate.

10 of 20 workers in an envelope-making factory developed contact dermatitis. The cause was dibutyl maleinate, which was added to a polyvinylacetate glue. Dibutyl maleinate is a strong sensitizer and should be withdrawn from industrial use.

Adhesives

Occupational dermatitis to 2,3-epoxypropyl trimethyl ammonium chloride.

4 workers developed hand dermatitis in an automated starch modification process plant. 2,3-epoxypropyl trimethyl ammonium chloride (EPTMAC), a quaternary ammonium compound used as a cationizing chemical, produced allergic reactions in all 4 patients. They had only been in contact with EPTMAC for a short time before developing dermatitis, which indicates that EPTMAC is a strong sensitizer. Immunohistochemistry and electron microscopy showed the features of an allergic patch test. An industrial hygiene project was initiated at the factory to prevent new cases. It revealed many risks of skin contact with the process chemicals. Thus an automated process does not guarantee protection.
