As a control group, sex\u2010matched adult patients were randomly selected. The results and characteristics of the two groups were compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The median age of 112 patch tested pediatric patients was 16 (range 2\u201317) years. Of the children, 35.5% had at least one positive reaction, significantly less than the 56.6% for adults. The five most common pediatric allergens were nickel sulfate (12.1%), potassium dichromate (8.0%), methylisothiazolinone (7.1%), fragrance mix II (6.0%), and carba mix (5.4%). Although similar, the 10 most common allergens of the groups differed in order. Positive reactions to cosmetic allergens were significantly less frequent among the children. Many allergens remained entirely negative.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The prevalence of positive reactions was lower in children, varying by population and region. The top\u201010 pediatric and adult causative allergens were almost identical. We recommend using the same baseline patch test series for children and adults in our region.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cod.13672","type":"journal-article","created":{"date-parts":[[2020,7,22]],"date-time":"2020-07-22T11:10:55Z","timestamp":1595416255000},"page":"34-40","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Pediatric
