BACKGROUND Continual surveillance based on patch test results has proved useful for the identification of contact allergy. OBJECTIVES To provide a current view on the spectrum of contact allergy to important sensitizers across Europe. PATIENTS/METHODS Clinical and patch test data of 19 793 patients patch tested in 2005/2006 in the 31 participating(More)
BACKGROUND Photoallergic contact dermatitis can be difficult to diagnose if not appropriately investigated. Currently, the most common U.K. photoallergens appear to be sunscreen chemicals. The investigation of choice is photopatch testing (PPT), which is probably underused. In part, this is due to differences in methodology and results interpretation. (More)
A recent epidemiologic survey in the UK revealed that 23% of women and 13.8% of men experience some sort of adverse reaction to a personal care product over the course of a year. Although most of these reactions may be due to subjective sensory irritation, various studies reveal that up to 10% of dermatologic patients who are patch tested are allergic to(More)
BACKGROUND To date, only a few cohorts of patients with allergic cheilitis have been described, most of them from Australia and Asia. OBJECTIVE To establish the prevalence of cheilitis in a UK specialist contact dermatitis clinic and to identify the most common allergens. METHOD We analyzed our patch-test database in a tertiary referral center in the(More)
Since January 2001, the European Surveillance System on Contact Allergies (ESSCA), supported by European Union funding (contract QLK4-CT-2001-00343), has started to collect patch-test data. This comprises a standardized clinical history and the patch-test results using the European standard series, from 17 centres in 9 European countries listed above. In(More)
Contact allergy to and allergic contact dermatitis from methyldibromo glutaronitrile (MDBGN) have frequently been reported. As there has been no agreement on which MDBGN test preparation to use, a study was initiated to help determine the optimal patch test preparation for MDBGN. 2661 consecutively patch tested patients at 11 test clinics representing 9(More)
Contact allergy to and allergic contact dermatitis from methyldibromo glutaronitrile (MDBGN) have frequently been reported. This study was initiated to help determine the optimal patch test preparation for MDBGN. In 51 patients with a doubtful or a positive patch test reaction to at least 1 of 4 test preparations with MDBGN in petrolatum at 1.0% w/w, 0.5%,(More)
Chronic inflammatory ear disease comprises a wide range of conditions. Although contact allergy to topical medicaments is common in such conditions, the causes of these reactions have not been examined in a large series for over a decade. Our aim was to investigate the major sensitizers recorded in 179 patients over the last 17 years. Medicament contact(More)
