Possibly hazardous chemical substances and mixtures need to be clearly and correctly classified and labelled, in order for their hazards to be properly identified and communicated. As dermatologists may encounter cases of harm to patients induced by chemicals, such as chemical burns, and irritant and allergic contact dermatitis, it is essential for them to be aware of the EU CLP Regulation and its potential pitfalls. Manufacturers are required by CLP to classify their products according to the rules given in the CLP Regulation...

BACKGROUND: Compositae dermatitis was originally described as airborne contact dermatitis. More recent studies have reported a wider clinical spectrum, but often in polysensitized patients. OBJECTIVE: To evaluate the clinical features of patients sensitized to Compositae only. PATIENTS/METHODS: Consecutive Compositae-sensitive eczema patients, tested between 1990 and 2015, who, at the patch testing session diagnosing their Compositae allergy, were found to be sensitized only to the plant family, were included...

INTRODUCTION: The aim of our study was to identify the prevalence and risk factors of medical adhesive-related skin injuries (MARSI) at peripherally inserted central catheters (PICC) insertion site in oncology patients. METHODS: A cross-sectional observational study lasting two weeks was carried out in four inpatient departments. Skin assessment data and photographs of skin were collected during PICC maintenance. Other related information came from medical records...

BACKGROUND/OBJECTIVES: Childhood allergic contact dermatitis is recognized as a significant clinical problem. The objective was to evaluate the rate of positive patch tests in Israeli children with clinically suspected allergic contact dermatitis, identify possible sex and age differences, compare results with those in Israeli adults, and review pediatric studies in the literature. METHODS: The study sample included 343 children and adolescents (197 female, 146 male; 1-18 years of age, mean age 11...

70-year-old white man presented with a 6-week history of an acute pruritic eruption in the axillary vaults, inguinal folds, and central lumbar area. Due to the severity of the pruritus, the patient was evaluated in the emergency department. He was treated with intramuscular triamcinolone, oral fluconazole, clobetasol cream, and miconazole powder, which provided only minimal relief. The patient had presented with brightly erythematous patches in the axillary vaults and inguinal folds with numerous erythematous, scaly, coalescing papules and plaques agminated on the lumbar region (Figure)...

The first patient was a 41-year-old white man who was referred to the dermatology clinic with a 2-year history of numerous erythematous, hypoesthetic, poorly demarcated papules and plaques present on the trunk, buttocks, and bilateral upper and lower extremities (Figures 1 and 2). The lesions had initially begun as localized erythematous plaques on the right flank, and were diagnosed and treated as cellulitis and allergic contact dermatitis by primary care on separate occasions, with no resolution and continued gradual but persistent spread...

A comparison between responses to allergens based on the TRUE Test(®)(TT) and IQ(®) Chamber (IQC) in Europeans has been previously reported, however, no such study has been performed in Asians. To compare allergen responses using the TT and IQC (using the Korean standard series) in order to gather more information regarding the positive response rates for each allergen and the clinical value of IQC. Suspected contact dermatitis patients were enrolled and tested with 18 allergens using the TT and IQC. The test was performed in 214 patients...

Cutaneous pseudolymphoma (CPL) is a reactive polyclonal T- or B-cell lymphoproliferative process. CPL may appear as localized or disseminated skin lesions. While most cases of CPL are idiopathic, they may also occur as a response to, for example, contact dermatitis, arthropod reactions, and bacterial infections. CPL can be classified based on its clinical features, but all variants have similar histopathological patterns of either predominantly B-cell infiltrates, T-cell infiltrates, or mixed T/B-cell infiltrates...

BACKGROUND: Body piercing provides a unique route of metal exposure. OBJECTIVE: The aim of this study was to update previous analyses using the North American Contact Dermatitis Group data comparing pierced and unpierced individuals. METHODS: This was a retrospective cross-sectional analysis of 17,912 patients patch tested by the North American Contact Dermatitis Group from 2007 to 2014 for demographics, positive reactions to metals (nickel, cobalt, chromium), and detailed analysis of nickel reactions by age, sex, and source of exposure...

Endogenous electrophilic fatty acids mediate anti-inflammatory responses by modulating metabolic and inflammatory signal transduction and gene expression. Nitro-fatty acids and other electrophilic fatty acids may thus be useful for the prevention and treatment of immune-mediated diseases, including inflammatory skin disorders. In this regard, subcutaneous (SC) injections of nitro oleic acid (OA-NO2), an exemplary nitro-fatty acid, inhibit skin inflammation in a model of allergic contact dermatitis (ACD). Given the nitration of unsaturated fatty acids during metabolic and inflammatory processes and the growing use of fatty acids in topical formulations, we sought to further study the effect of nitro-fatty acids on cutaneous inflammation...

To investigate the expression profile of monocyte chemoattractant peptide-1 (MCP-1) by keratinocytes after nickel exposure and to identify its role for leucocyte migration during nickel-induced occupational allergic contact dermatitis (OACD), 26 workers diagnosed with nickel-induced OACD were enrolled. Skin biopsies from the positive nickel-challenged sites at different time points were assessed by immunohistochemistry (IHC) for MCP-1, CD68, CD45RO, and in situ hybridization (ISH) for MCP-1, using chronic periumbilical dermititis as controls...

REVIEW
Philipp R Esser, Stefan F Martin
Contact sensitization is the initial process involved in the development of an allergic reaction to xenobiotic environmental substances. Here, we briefly describe the differences between irritant and allergic contact dermatitis. Then, we highlight the essential steps involved in the development of an ACD reaction, i.e., the protein binding of haptens, genetic factors influencing the penetration of sensitizers into the skin, the different mechanisms driving the initial development of an inflammatory cytokine micromilieu enabling the full maturation of dendritic cells, the role of pre- and pro-haptens, antigen presentation and T cell activation via MHC and CD1 molecules, dendritic cell (DC) migration, and potential LC contribution as well as the different T cell subsets involved in ACD...

Contact with poison ivy plants is widely dreaded because they produce a natural product called urushiol that is responsible for allergenic contact delayed-dermatitis symptoms lasting for weeks. For this reason, the catchphrase most associated with poison ivy is "leaves of three, let it be", which serves the purpose of both identification and an appeal for avoidance. Ironically, despite this notoriety, there is a dearth of specific knowledge about nearly all other aspects of poison ivy physiology and ecology...

BACKGROUND: Calcipotriol, a synthetic vitamin D analogue, is widely used for the topical treatment of psoriasis. It often causes irritant reactions, whereas allergic contact dermatitis has less commonly been reported. OBJECTIVES: To report on 6 patients (among them an 11-year-old child) who presented with eczematous lesions complicating pre-existing dermatitis, observed in our tertiary referral patch test clinic between 2004 and 2016. METHODS: Patch tests were performed with the commercial preparation used by the patients and/or its ingredients, including calcipotriol (2 or 10 µg/ml in isopropyl alcohol), according to ESCD patch test guidelines...

The first reported cases of allergic contact dermatitis from acrylates in manicure procedures in relation to the application of porcelain nails were published decades ago. The frequency of sensitization has increased due to the introduction of the so-called permanent nail polish containing photo-bonded acrylates, mainly involving the beauticians who apply them, and to a lesser extent, the consumers. The recent commercialized permanent polish kits for domestic use could trigger even higher degrees of sensitization...
