Summary Background Allergic contact dermatitis (ACD) caused by nail acrylates, also including methacrylates and cyanoacrylates here, is being increasingly reported. Methods A retrospective study in 11 European Environmental Contact Dermatitis Research Group (EECDRG) clinics collected information on cases of ACD acrylates diagnosed aimed testing between 2013 2015. Results Among 18 228 studied patients, 136 had (0.75%; 95%CI: 0.60–0.90), representing 67.3% (95%CI: 60.4–73.7) acrylates. There...
The use of methylisothiazolinone (MI) in cosmetic products has caused an unprecedented epidemic MI contact allergy. Current data concerning exposures at a European level are required.To describe demographics and for patients with allergy.Eleven dermatology departments from eight countries prospectively collected between 1 May 31 October 2015 among consecutive who had positive patch test reactions to (2000 ppm aq.).A total 6.0% (205/3434; range 2.6-13.0%) MI. Dermatitis most frequently...
Abstract Background Methylisothiazolinone (MI) has caused an unprecedented epidemic of contact allergy in Europe and elsewhere. Subsequently, regulatory action been taken, at least Europe, aiming reducing risk MI sensitization. Objective To follow‐up on the prevalence to consecutively patch tested patients assess spectrum products containing or methylchloroisothiazolinone (MCI)/MI positive which elicited current allergic dermatitis. Methods A cross‐sectional survey was performed 2016 2017,...
ABSTRACT Background The Aloe vera plant has been used for an array of ailments, including skin diseases. Recent experimental research have substantiated the presence biologically active compounds in gel, but there are few controlled, clinical trials to assess efficacy. Objective To test effect a commercial, preserved, otherwise untreated gel psoriasis. Patients/methods Forty‐one patients with stable plaque psoriasis were included randomized, double‐blind, placebo‐controlled right/left...
Background. Painters are among the occupational groups that most commonly experience contact dermatitis, but few investigations exist concerning this occupation. Objectives. To characterize painters with dermatitis and identify common allergens associated Materials methods. All patch test results of 219 1095 matched controls registered by Danish Contact Dermatitis Group between 2001 2010 were analysed. Results. Hand eczema ( p < 0.0001) observed significantly more often in than group...
Background Hand eczema (HE) is a frequent, long‐lasting disease with both personal and societal repercussions. Consequently, more information needed on factors that maintain symptoms. Objectives In this study, patients HE were followed for 6 months from the first visit to dermatologist identify associated severe poor prognosis. Methods Study participants 799 nine dermatological clinics in Denmark. Severity assessment of was done at baseline 6‐month follow‐up using Eczema Index (HECSI) by...
Summary Background Occupational contact dermatitis among hairdressers is frequent, owing to daily exposure irritants and allergens. Objectives To identify sensitization the most common allergens associated with occupation of hairdressing. Methods Patch test results 399 1995 matched controls dermatitis, registered by Danish Contact Dermatitis Group between January 2002 December 2011, were analysed. All patients patch tested European baseline series, additionally hairdressing series. Results (...
To investigate the frequency of Compositae sensitivity, recently‐developed sesquiterpene lactone mix (SL mix) was included in standard patch lest series. Patients with positive reaction to this or patients suspected having a allergy were supplementary tested mix, consisting ether extracts 5 European plants. In first year, 686 SL and 79 mix. A total 31 Compositae‐sensitive (4.5%) found. The reactions either mixes equal, but only 17 30 both mixes. Testing individual ingredients showed frequent...
Results of aimed patch testing with constituents sesquiterpene lactone (SL) mix, Compositae mix (CM) and other extracts allergens in 190 Compositae-allergic patients detected an 8-year period are presented. Feverfew CM elicited positive reactions most frequently, followed by tansy, wild chamomile, yarrow arnica, whereas dehydrocostus SL was the frequent elicitor reactions, alantolactone costunolide. Chrysanthemum (Dendranthema) marguerite (Argyranthemum frutescens) were important suspected...
The aim of this study was to assess the strength any association between sensitization 'new' fragrance compounds and Compositae, mix, Myroxylon pereirae resin colophonium, respectively. Consecutive eczema patients were tested with a series essential oils selected another oxidized terpenes in connection European multicentre projects. Contact allergy either frequently detected, 5% 318 4.6% 262 persons tested, both had statistically significant colophonium mix sensitization. individual results...
Background: The preservative methyldibromo glutaronitrile (MDBGN) has been banned, first from stay‐on, and later rinse‐off cosmetics, in the EU countries because of increasing rates contact allergy. Objectives: To evaluate frequency allergy to MDBGN among patients patch tested by Danish Contact Dermatitis Group just before following regulatory decisions. Patients/Methods: data set comprised 19 279 consecutive eczema 2003–2007 with 0.3% petrolatum (pet.) or, a minority patients, Euxyl K™ 400...
Background. Epoxy resin monomers are strong skin sensitizers that widely used in industrial sectors. In Denmark, the law stipulates workers must undergo a course on safe handling of epoxy resins prior to occupational exposure, but effectiveness this initiative is largely unknown. Objectives. To evaluate prevalence contact allergy monomer (diglycidyl ether bisphenol A; MW 340) among patients with suspected dermatitis and relate occupation work‐related consequences. Patients/methods. The...
Summary Background Blue‐collar workers have a high risk of occupational contact dermatitis, but epidemiological studies are scarce. Objectives To investigate allergic dermatitis in blue‐collar with registered by the D anish C ontact ermatitis G roup. Methods A retrospective analysis patch test data from 1471 and matched controls tested between 2003 2012 was performed. logistic regression used to for associations. Results The often had hand ( p < 0.001). Atopic less commonly observed among...
The aim of the study was to assess distribution different types occupational eczema among employees in floristry and detect allergens most commonly involved. Based on a postal questionnaire, 253 gardeners greenhouse workers with skin symptoms 52 randomly-selected without were examined patch tested. Routine tests comprised standard series, Compositae mix, feverfew 3 fungicides, additional testing based case records. 184 persons from symptom group 1 random had eczema. Irritant contact...
Routine patch testing with sesquiterpene lactone (SL) mix, supplemented Compositae mix (CM) and other extracts allergens where appropriate, was evaluated over an 8‐year period. 190 of 4386 patients tested (4.3%) were Compositae‐sensitive, 143 females (mean age 51.5 years) 47 males 55 years), 83% reactions considered clinically relevant. 22% suspected occupational sensitization/dermatitis. 62% had a contact allergy to 2 or more compounds, most often nickel, fragrance colophonium. SL detected...
The terpene l-carvone is one of the main constituents spearmint oil. sensitizing potential has been considered low, but it occasionally caused contact allergy in users toothpaste and chewing gum. l-Carvone also an oxidation product d-limonene that occurs solvents used increasingly industry. We included 5% pet. standard patch test series. In 1st year, 541 patients were tested 15 (2.77%) had positive, 12 doubtful positive (?+) reactions to l-carvone. strongest observed 9 with concomitant...
