Background: Job-related allergic contact dermatitis (ACD) mayprolong the disease duration, increase disabilities, and decreasethe patient’s quality of life. The aim of this study was to determinecommon allergens causing ACD, investigating certain featuresof the disease and evaluating its relation to the patients’ jobs.Method: In this cross-sectional study, relevant data was obtainedfrom patch test clinics at the Center for Research and Trainingin Skin Diseases and Leprosy, Tehran University of MedicalSciences, and two private dermatology clinics in Tehran, Iran.Nine hundred and forty six patients from different regions of Iranwith a probable diagnosis of ACD were recruited into the study.Patch testing was used as the gold standard test to differentiateACD from other differential diagnoses.Result: Of 946 studied patients with a probable diagnosis ofACD, 649 (68.6%) cases were females. The mean age ± standarddeviation (SD) of the patients was 31.9 ± 12.3 years. Five hundredand twenty eight (55.7%) cases had positive patch test results toat least one tested allergen. Comparing job-related and non jobrelatedACD patients revealed that while there was a significantdifference in the mean age of the two group (30.6 ± 11.3 vs.32.7 ± 12.9 years in job-related and non-job-related groups,respectively) (P=0.016), there were no significant differences inthe gender distribution, number of positive patch tests, frequencyof allergens, reaction time, and severity of reactions between thetwo groups. Nickel sulphate and cobalt chloride were the twomost common allergens in both groups.Conclusion: Job-related patients were younger and most of themwere female compared to non job-related patients. However,other characteristics were not different between the two groups.

Background: The standard patch test is known as the most reliable test to identify and confirm causative agents of allergic contact dermatitis (ACD). Previous studies have shown that the prevalence of specific allergens varies by geographic area. The results of patch test in patients visiting our dermatology clinics with suspected ACD were prospectively investigated and compared with those reported in the literature of Iran.Method: We performed the European Standard Series patch test produced by Almiral Hermal GmbH, containing 28 allergens in a group of 100 patients (55 females and 45 males) with suspected ACD who were referred to Emam Reza and Ghaem Hospitals, Mashhad, in 2010-2011. The tests were read after 2 and 4 days.Result: Fifty-four percent of the patients had 1 or more positive reactions of which 65% were relevant to current or past dermatitis. Positive reactions were due to 12 allergens. The most frequent allergens were nickel sulfate (25%) and potassium
