Health care personnel form the 5th category at major occupational risk of skin disease in Italy. The aim of this study was to assess the prevalence and clinical relevance of contact dermatitis in a group of 1301 employees of the Perugia Monteluce Hospital (658 females and 643 males; mean age 39.8 years) who answered a self-administered questionnaire elaborated by the authors. The subjects with anamnestic hand dermatitis and/or atopic mucosal reactions were clinically examined and submitted to skin tests (patch and/or prick tests). Contact dermatitis of the hands and/or forearms occurred in 21.2% and was significantly more frequent (p < 0.001) in women, subjects under 31 years of age, workers in internistic and surgical fields, cleaners and nurses. In the majority of cases (94.9%), the lesions were irritant in origin and mainly related to disinfectants (especially, chlorhexidine gluconate and glutaraldehyde) and gloves (latex proteins and starch glove powder, rather than accelerators and additives of rubber). Finally, atopy seemed to favour the onset of hand dermatitis. The importance of these results for preventive measures of contact dermatitis in hospital employees is discussed.
Budesonide, reported as a contact sensitizer 15 years ago (1), is a synthetic non-halogenated corticosteroid, included in class B of Coopman et al. (2).
The aetiologic evaluation of adverse cutaneous reactions to penicillins is still not an easy problem to solve. Skin testing is usually carried out intradermally with benzylpenicilloyl polylysine (BPO-PPL) and minor determinant mixture (MDM), but these are often unsuitable for the detection of sensitivity to betalactam antibiotics. 101 selected subjects, with different cutaneous reactions to betalactams and with a clinical history of positive challenge, were skin tested (patch test, prick test, intradermal test) with a standard betalactam series (amoxycillin, sodium penicillin G, ampicillin, bacampicillin, aztreonam, ceftriazone, BPO-PPL, MDM). 1 or more positive reactions to skin tests, mainly to intradermal tests, were observed in 47.5% of the subjects studied, especially in those with maculopapular eruptions, urticaria/angioedema and drug reactions caused by ampicillin and amoxycillin. Cross-sensitivity was demonstrated in 22.8% of cases and was due almost solely to the semisynthetic penicillins. Finally, to increase the yield in detecting positive patients, it is necessary that ampicillin and amoxycillin be tested in addition to major and minor determinants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
