Contact sensitization among ceramics workers.

139 workers from 3 ceramics factories underwent dermatological and allergological examination, using standard and occupational patch test series, in order to evaluate the prevalence of dermatitis and contact sensitization, to identify the most important sensitizing substances in the ceramics industry, and to correlate the results with possible risk factors such as atopy. Hand dermatitis had affected 37% of the subjects examined. 27% of the workers were sensitized to 1 or more allergens. Of 52 subjects with dermatitis, 37% had allergic contact dermatitis and 63% irritant contact dermatitis. 18 subjects were found to be sensitized without showing any previous or present clinical symptoms. Atopy tended towards correlation with the overall incidence of dermatitis, though not with the prevalence of sensitization.

Patch and prick test study of 593 healthy subjects.

593 recruits selected by the Military Health Service as being healthy and without a history of present or previous dermatitis, or ocular refraction defects, were patch tested with the GIRDCA (Italian Research Group on Contact and Environmental Dermatitis) standard series. Of these, 336 were also patch tested with substances used in the processing and dyeing of textiles and prick tested with 8 major allergens. 74 (12.5%) reacted to 1 or more substances. The most frequent sensitizers were: thimerosal (28 cases), ammoniated mercury (7 cases), phenol-formaldehyde resin (6 cases), parabens, nickel and Disperse Red 17 (4 cases each). 113 recruits reacted to 1 or more prick test allergens. We have demonstrated the importance of establishing such reference values in healthy groups for the correct evaluation of data collected from selected groups.

[Erythema multiforme associated with contact sensitization. Description of 6 clinical cases].

Allergic contact dermatitis generally presents itself as an eczematous eruption. However, some allergens, such as plants, exotic woods, topical medications and chemicals have been reported as causing an erythema multiforme-like eruption. We describe 6 patients, 4 women and 2 men ranging from 28 to 66 years. They showed erythematous urticarial papules, plaques and target-lesions similar to the manifestations previously reported as "erythema multiforme-like eruption". On the basis of the positive epicutaneous tests, the aetiological agents of these reactions are presumed to be Idoxuridine, textile dyes, deodorants, paraphenylenediamine and pyrrolnitrin. The clinical pattern, the histopathological features and the pathogenesis are discussed. Finally, the clinical and anamnestic criteria indicating the opportunity of performing patch tests in patients showing an atypical erythema multiforme are suggested.
