Patch tests carried out with the standard series of the International Contact Dermatitis Research Group and with a series of penicillins revealed positive reactions in 22 (35\/162) and 6.9% (11\/158), respectively. In 21.5% (33\/152) positive intracutaneous tests to cilligen and\/or penicillin G were observed. 35% (51\/147) of the patients had one or more positive intracutaneous tests with inhalants. Scratch tests with food allergens showed positive reactions in 12.5% (12\/95). There was no difference in results between patients with idiopathic urticaria or angio-oedema and those with physical urticaria. The value of these findings is discussed. Most of the patients with penicillin allergy, were recommended to be on a diet free from milk and milk products. In 50% this was successful.<\/jats:p>","DOI":"10.1159\/000250152","type":"journal-article","created":{"date-parts":[[2009,10,27]],"date-time":"2009-10-27T05:20:54Z","timestamp":1256620854000},"page":"151-159","source":"Crossref","is-referenced-by-count":19,"title":["Skin Testing in Chronic Urticaria"],"prefix":"10.1159","author":[{"given":"W.J.","family":"Boonk","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.G.","family":"van Ketel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,10,14]]},"container-title":["Dermatologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/250152","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000250152","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T09:42:14Z","timestamp":1777542134000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000250152"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,10,14]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000250152","archive":["Portico"],"relation":{},"ISSN":["0011-9075","2571-7197"],"issn-type":[{"value":"0011-9075","type":"print"},{"value":"2571-7197","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,10,14]]}}}
