BACKGROUND: Contact urticaria (CU) and protein contact dermatitis (PCD) are mainly induced by an immediate, IgE-mediated immunological mechanism. Immediate sensitization is also linked to asthma and/or allergic rhinitis. OBJECTIVES: To report causes of work-induced CU and PCD, and to evaluate the occurrence of concomitant airway diseases. METHODS: We retrospectively reviewed the patient files of cases diagnosed with CU or PCD at the Finnish Institute of Occupational Health during 1995-2011...

BACKGROUND: Allergic reactions to tattoos are not uncommon. However, identification of the culprit allergen(s) remains challenging. OBJECTIVES: We present a patient with papulo-nodular infiltration of 20-year-old tattoos associated with systemic symptoms that disappeared within a week after surgical removal of metal osteosynthesis implants from his spine. We aimed to explore the causal relationship between the metal implants and the patient's clinical presentation...

BACKGROUND: The high risk of occupational skin disease among hairdressers, caused by skin exposure to irritants and sensitizers, such as hair dye substances, is of great concern. OBJECTIVES: The aim of the present study was to assess how the various tasks involved in hair dyeing contribute to hairdressers' exposure to hair dye, in order to enable the formulation of well-founded recommendations on working routines that will reduce exposure and prevent occupational disease...

BACKGROUND: Antiretroviral drug hypersensitivity in HIV patients is common. Publications have shown that Abacavir (ABC) patch testing is useful in confirming ABC hypersensitivity in 24-50% of cases with a 100% sensitivity of HLA-B*5701 in patch test positive cases. However, Nevirapine (NVP) patch testing has not been reported. OBJECTIVES: (1) To evaluate the usefulness and safety of NVP patch testing in Thai HIV patients with NVP hypersensitivity. (2) To assess the correlation of positive patch tests with HLA-B*3505...

BACKGROUND: During rubber vulcanization, new compounds can be formed. OBJECTIVES: To report a case of allergic shoe dermatitis in which the search for the allergen ultimately led to the identification of dimethylthiocarbamylbenzothiazole sulfide (DMTBS). METHODS: A female presented with eczema on her feet after wearing Sperry Top Sider® canvas sneakers. Patch testing was performed with the European baseline series, additional series, shoe materials, and extracts of shoe materials...

BACKGROUND: Recent animal tests have indicated cross-reactivity between methylisothiazolinone (MI), octylisothiazolinone (OIT), and benzisothiazolinone (BIT). OBJECTIVES: To retrospectively analyse concomitant reactions to different isothiazolinones in patients in an occupational dermatology clinic during the ongoing MI contact allergy epidemic. METHODS: We searched patch test files (January 2012 to February 2017) for patients with allergic reactions to OIT, BIT, and MI, and analysed their patch test results, occupations, exposure, and diagnoses...

BACKGROUND: Patch testing following a standardized protocol is reliable for identifying the culprit drug in cutaneous adverse drug reactions (CADRs). However, these patch tests (PTs) require pharmaceutical material and staff, which are not always easily available. OBJECTIVES: To evaluate an extemporaneous PT method in CADRs. METHODS: We retrospectively analysed data for all patients referred to our department between March 2009 and June 2013 for patch testing after a non-immediate CADR...

REVIEW

Nickel contact allergy remains a problem in EU countries, despite the EU Nickel Directive. To study the prevalence of nickel allergy in EU countries following the implementation of the EU Nickel Directive, we performed a systematic search in PubMed for studies that examined the prevalence of nickel allergy in EU countries published during 2005-2016. We identified 46 studies: 10 in the general population and 36 in patch tested dermatitis patients. A significantly lower prevalence of nickel allergy after than before the implementation of the EU Nickel Directive was found in women aged 18-35 years (11...

BACKGROUND: Contact allergy to aluminium has been reported more frequently in recent years. It has been pointed out that positive patch test reactions to aluminium may not be reproducible on retesting. OBJECTIVES: To investigate possible variations in patch test reactivity to aluminium over time. METHODS: Twenty-one adults, who had previously reacted positively to aluminium, were patch tested with equimolar dilution series in pet. of aluminium chloride hexahydrate and aluminium lactate, four times over a period of 8 months...

Allergic contact dermatitis is one of the most frequent forms of skin inflammation. Very often, we are exposed to mixtures of allergens with varying potencies, doses/areas, and exposure times. Therefore, improved knowledge about immune responses to combinations of contact allergens is highly relevant. In this article, we provide a general introduction to immune responses to contact allergens, and discuss the literature concerning immune responses to mixtures of allergens. According to the existing evidence, increased responses are induced following sensitization with combinations of allergens as compared with single allergens...

BACKGROUND: Temporary tattoos made with an extract of the jagua fruit (Genipa americana L.) are becoming increasingly popular. It is claimed that it is 'dermatologically tested' and does not contain p-phenylenediamine. Extracts of jagua and gardenia fruits have been used by indigenous people in South America, as well as in traditional Chinese medicine, for centuries. Genipin is currently used for its cross-linking effect in the manufacture of polysaccharides, and is being investigated for its anti-inflammatory and other properties...

BACKGROUND: Knowledge about the relations between skin exposures, skin symptoms and contact allergy in adolescents is limited. OBJECTIVES: To explore self-reported skin exposures and skin symptoms in girls and boys, and to assess the associations between exposures, symptoms and contact allergy at age 16 years. PARTICIPANTS AND METHODS: In all, 3115 adolescents from the population-based BAMSE birth cohort answered a questionnaire at age 16 concerning various skin exposures and related skin symptoms...

BACKGROUND: Occupational exposure to cobalt is well established in hard metal manufacture. Cobalt is known to cause contact allergy, asthma, hard metal lung disease, and lung cancer. The relationship between skin exposure and uptake determined in blood has not been extensively investigated. OBJECTIVE: To examine whether skin and inhalable air exposure to cobalt contributes to uptake, determined as cobalt in blood, in a hard metal manufacturing factory. METHODS: The amount of cobalt on the skin found with an acid wash technique, the air concentrations of inhalable cobalt and cobalt blood concentrations were determined and correlated in exposed workers...

BACKGROUND: Allergic contact dermatitis (ACD) caused by (meth)acrylates has been described both in occupational and in non-occupational settings. OBJECTIVES: To evaluate the clinical patterns, the most frequent allergens and the prognosis in patients sensitized to (meth)acrylates in long-lasting nail polish. METHODS: The files of patients with ACD caused by (meth)acrylates in long-lasting nail polish diagnosed between January 2013 and June 2016 in four dermatology departments in Spain were reviewed...

BACKGROUND: Isocyanates are used in polyurethane production. Dermal exposure to isocyanates can induce contact allergy. The most common isocyanate is diphenylmethane diisocyanate used for industrial purposes. The isomer diphenylmethane-4,4'-diisocyanate (4,4'-MDI) is used in patch testing. Diphenylmethane-4,4'-diamine (4,4'-MDA) is its corresponding amine. Concurrent reactions to 4,4'-MDI and 4,4'-MDA have been reported, as have concurrent reactions to 4,4'-MDI and dicyclohexylmethane-4,4'-diisocyanate (4,4'-DMDI)...

BACKGROUND: Identification of the allergenic potency of chemicals is a key step in the safety assessment process. Predictive assays that require no or few animals are needed. OBJECTIVES: To develop an alternative in vitro mouse bone marrow-derived dendritic cell (BMDC) assay to determine the allergenic potential of chemicals. METHODS: BMDCs were exposed to well-known allergens and to non-allergenic chemicals. Surface marker expression and cytokine release of BMDCs were analysed after treatment...
