The dorsal pattern was more prevalent in atopic patients, compared to nonatopic patients. Irritant contact dermatitis was the most frequent diagnosis (55.3%), followed by allergic contact dermatitis (24.4%) and dyshidrotic eczema (20.3%). Among housewives, health workers, and mechanics, irritants were of much greater importance than allergens whereas among hairdressers and bricklayers, the opposite was found. The prevalence of personal atopy did not differ significantly between different types of HD. Nickel sensitivity was much less frequent in irritant contact dermatitis than in allergic contact dermatitis or dyshidrotic eczema. The distribution of clinical patterns was similar.\u0000\u0000\u0000CONCLUSION\u0000This study suggests that different etiologic diagnoses of HD cannot be distinguished by clinical pattern, prevalence of personal atopy, or nickel-sensitivity.","PeriodicalId":7612,"journal":{"name":"American journal of contact dermatitis : official journal of the American Contact Dermatitis Society","volume":"1 1","pages":"63-8"},"PeriodicalIF":0.0,"publicationDate":"2003-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77790764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the majority of cases, subjects were polysensitized (92.8%), but 7.2% of subjects were patch-test positive only to palladium. Of palladium-sensitized patients, 40.5% complained of hand dermatitis, 47.4% complained of body dermatitis, and 1.7% complained of burning mouth syndrome. Palladium sensitization is significantly related to female sex (OR = 3.08; 95% CI, 2.07-4.61) and to sensitization to other metals, with a maximum for nickel sulfate (OR = 32.9; 95% CI, 21.3-51.5).\u0000\u0000\u0000CONCLUSION\u0000Sensitization to palladium is increasing by the year, reaching high values, but its role in reducing sensitization and symptoms is still unclear because of the frequent cosensitization with nickel and the low number of monosensitized patients with relevant sensitizations.
