BACKGROUND: In 2014, the fragrance hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC) was excluded from the Swedish baseline series. OBJECTIVES: To study (i) whether fragrance mix (FM) II with 5% HICC detects more positive reactions than FM II with 2.5% HICC, and (ii) the reproducibility of patch testing with HICC. METHODS: Two thousand one hundred and eighteen dermatitis patients at five Swedish dermatology departments were consecutively tested with FM II 14% pet...

BACKGROUND: Henna has a very low allergic potential, and severe allergic contact dermatitis is mainly caused by p-phenylenediamine (PPD), which is added to temporary black 'henna tattoos', and potentially also by some heavy metals. OBJECTIVE: To determine the presence of, and quantify, Lawsone, PPD and heavy metal contaminants (cobalt, nickel, lead, and chromium) in commercial temporary black henna tattoo mixtures (n = 25) sold in Turkey. METHODS: Lawsone and PPD concentrations were analysed with high-performance liquid chromatography, and heavy metal quantification was performed with inductively coupled plasma mass spectrometry...

BACKGROUND: Hairdressers are at risk of developing occupational contact dermatitis because of their intense contact with wet work in combination with chemicals. OBJECTIVES: To perform an analysis of a cohort study of hairdressers with occupational contact dermatitis recognized in the period 2006-2011, focusing on individual and environmental factors associated with the disease. METHODS: The study was a descriptive, register-based survey including all hairdressers with recognized occupational contact dermatitis in Denmark in the period January 2006 to September 2011...

BACKGROUND: It has been suggested that lifestyle factors such as smoking, being overweight and stress may influence the prevalence and severity of hand eczema. OBJECTIVES: To investigate the association between lifestyle factors and hand eczema severity in a cohort of patients with work-related hand eczema. METHODS: Individuals with work-related hand eczema notified in the period between June 2012 and November 2013 were included in this questionnaire-based cross-sectional study...

BACKGROUND: Five workers from a plant manufacturing concrete wall panels and beams were referred to our department because of suspected occupational dermatitis. When patch tested, 3 workers reacted to potassium dichromate. Four workers reacted to ethylenediamine dihydrochloride, without any obvious exposure. Owing to the high proportion of workers with recent-onset skin disease, an investigation of all workers at the plant was initiated. OBJECTIVES: To investigate the prevalence of occupational dermatitis and contact allergy in the workers at the plant...

BACKGROUND: Thiurams and dithiocarbamates are structurally related sensitizing rubber accelerators. OBJECTIVES: To study patterns of simultaneous patch test reactions to thiurams and dithiocarbamates at the Finnish Institute of Occupational Health in 1991-2015. METHODS: We searched the patch test files for patients with allergic reactions to thiuram mix, its four components, and three dithiocarbamates, and analysed patterns of simultaneous reactions to these test substances...

BACKGROUND: It is not fully understood where and how people are exposed to sensitizing metals. Much can be learnt from studying occupational settings where metals are handled. OBJECTIVES: To quantify cobalt (Co), chromium (Cr) and nickel (Ni) exposure on the skin and in the air, and urine levels, in dental technicians working with tools and alloys that may result in skin and respiratory exposure. METHODS: The metal skin dose was quantified with acid wipe sampling in dental technicians (n = 13)...

Immediate skin reactions are common in dermatological practice, but may often be overlooked. The main objective of this article is to provide an update of the literature concerning immediate-type reactions or contact urticaria/contact urticaria syndrome caused by cosmetic ingredients in terms of immediate clinical symptoms, positive reactions following open, scratch but, most often, prick testing, and sometimes the detection of specific IgE antibodies. To this end, a selective search in different medical literature databases was performed...

BACKGROUND: In the contact dermatitis literature, it is regularly stated that the patch test reactivity on various areas of the back differs; this might have a large impact on the reproducibility of patch testing. OBJECTIVES: To investigate the reproducibility of patch testing on the upper back with regard to the left as opposed to the right side and the medial as opposed to the lateral part of the upper back. The reproducibility over time and with regard to the reactivity pattern was also investigated...

BACKGROUND: Peristomal dermatitis is a common complication for the >700 000 patients in the United States with an ostomy. The role of stoma skin care products in peristomal dermatitis is poorly understood. OBJECTIVE: To evaluate stoma skin care products as a cause of peristomal dermatitis. METHODS: A retrospective chart review of patients with peristomal dermatitis at four academic hospitals from January 2010 to March 2014 was performed...

Patients with Compositae sensitization are routinely warned against the ingestion of vegetables, spices, teas and herbal remedies from this family of plants. The evidence for the occurrence of systemic allergic dermatitis caused by sesquiterpene lactone-containing plants is mostly anecdotal and based on statements from patients rather than scientific data. However, a few clinical reports on accidental sensitization and exposure and oral challenge prove the existence of this kind of reaction, most convincingly for strong contact allergens such as costunolide in bay leaves, and less so for weak allergens such as those of lettuce...

BACKGROUND: Amines in epoxy hardeners are significant causes of occupational allergic contact dermatitis among workers who use epoxy resin systems. OBJECTIVES: To describe a novel group of contact allergens: N-(2-phenylethyl) derivatives of the reactive amine 1,3-benzenedimethanamine (1,3-BDMA). METHODS: We describe the clinical examinations and exposure of 6 patients with occupational contact allergy to derivatives of 1,3-BDMA. RESULTS: Of the 6 patients, 4 were spray painters who used epoxy paints, 1 was a floor layer who handled a variety of epoxy coatings, and 1 was a worker in epoxy hardener manufacture...

BACKGROUND: Majantol® [2,2-dimethyl-3-(3-methylphenyl)propan-1-ol; CAS no. 103694-68-4] has been identified as a contact allergen in humans, despite the lack of sensitizing properties according to animal tests. The question was raised of whether impurities, specifically organochlorines, in Majantol® might have been the reason for positive patch test reactions in the past. OBJECTIVES: To assess the allergenic potential in terms of elicitation via patch testing with a standard market-quality version of Majantol® ('normal') with a normal content of organochlorine impurities, as compared with an ultra-purified version of Majantol® ('pure'), without detectable organochlorine impurities...

BACKGROUND: Cross-reactions and co-sensitizations are of great importance in understanding contact allergy and exposure sources. OBJECTIVES: To investigate common cross-reactions and co-sensitizations in p-phenylenediamine (PPD)-sensitized and toluene-2,5-diamine (TDA)-sensitized individuals. METHODS: From our patch test population, 8036 patients patch tested with the European baseline series were extracted. Readings had to be performed at least on day 3 according to ICDRG guidelines...
