A retrospective analysis of results from all patch tests performed on patients with suspected allergic contact dermatitis from January 1995 to December 1999 in the Social Hygiene Service, which provides a public dermatology service in Hong Kong, was undertaken. We aimed to explore the demographic data associated with positive reactions and the profile of contact sensitizing allergens in Hong Kong.<\/jats:p><jats:p><jats:bold>Methods\u2002<\/jats:bold> A total of 2585 patients were patch tested with the European standard series during the period. Most were Chinese, with a female\u2010to\u2010male ratio of 3\u00a0:\u00a02.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> One or more positive responses were noted in 1415 patients (54.7%). The most common allergen was nickel sulfate (24.4%), followed by fragrance mix (13.7%), cobalt chloride (8.7%), <jats:italic>p<\/jats:italic>\u2010phenylenediamine (6.0%), and balsam of Peru (5.7%). Nickel sensitivity was more common in female patients, and dichromate sensitivity was more common in male patients (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001). Female gender, an age of 40\u00a0years or below, truncal and upper limb involvement, absence of lower limb involvement, and a positive atopy history were significant risk factors for nickel sensitivity.<\/jats:p><jats:p><jats:bold>Conclusions\u2002<\/jats:bold> This study provides a profile of allergens responsible for allergic contact dermatitis in the public dermatology service in Hong Kong. A prospective study, using a larger panel of allergens, involving patients from both the private and public sectors, would provide a more comprehensive profile of contact allergens in Hong Kong and contribute to the establishment of a local standard series.<\/jats:p>","DOI":"10.1111\/j.1365-4632.2008.03437.x","type":"journal-article","created":{"date-parts":[[2009,9,17]],"date-time":"2009-09-17T12:00:11Z","timestamp":1253188811000},"page":"128-133","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["A retrospective study of 2585 patients patch tested with the European standard series in Hong Kong (1995\u201399)"],"prefix":"10.1111","volume":"47","author":[{"given":"Wai Sun","family":"Lam","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Loi Yuen","family":"Chan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stanley Ching Kong","family":"Ho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lai Yin","family":"Chong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Win Han","family":"So","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tze Wai","family":"Wong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,1,15]]},"reference":[{"key":"e_1_2_7_2_2","first-page":"175","volume-title":"Textbook of Contact Dermatitis","author":"Agner T","year":"2001"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0536.1996.tb02261.x"},{"key":"e_1_2_7_4_2","volume-title":"Hong Kong 2001 Population Census \u2013 Main Tables","author":"Census","year":"2002"},{"key":"e_1_2_7_5_2","first-page":"439","volume-title":"Textbook of Contact Dermatitis","author":"Wahlberg JE","year":"2001"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0536.2000.042006315.x"},{"key":"e_1_2_7_7_2","doi-asserted-by":"crossref","first-page":"450","DOI":"10.2340\/0001555572456460","article-title":"Allergic contact sensitization in an unselected Danish population.
