BACKGROUND: Occupational dermatitis affects the quality of life and productivity of workers. Studies on the subject are scarce in Brazil. It is estimated that the disease is underreported and that many affected patients do not seek health care. OBJECTIVES: To conduct an epidemiological analysis of occupational dermatitis notified via SINAN in Brazil from January 2007 to December 2012; evaluate the profile of patients assisted; and check the main etiological agents involved...

BACKGROUND: Preservatives are known causes of allergic contact dermatitis. OBJECTIVE: The aim of this study was to determine the prevalence of preservatives in each product category in the Contact Allergen Management Program and compare prevalence with reported rates of allergic contact dermatitis. METHODS: Contact Allergen Management Program product information was queried based on the 53 approved preservatives for cosmetic products by the European Union and Association of Southeast Asian Nations plus 5 additional preservatives used in US products...

The skin serves as the foremost barrier between the internal body and the external world, providing crucial protection against pathogens and chemical, mechanical, and ultraviolet damages. The skin is a central player in the intricate network of immune, neurologic, and endocrine systems. The endocannabinoid system (ECS) includes an extensive network of bioactive lipid mediators and their receptors, functions to modulate appetite, pain, mood, and memory, and has recently been implicated in skin homeostasis. Disruption of ECS homeostasis is implicated in the pathogenesis of several prevalent skin conditions...

Th2 immunity plays important roles in both protective and allergic responses. Nevertheless, the nature of antigen-presenting cells responsible for Th2 cell differentiation remains ill-defined compared with the nature of the cells responsible for Th1 and Th17 cell differentiation. Basophils have attracted attention as a producer of Th2-inducing cytokine IL-4, whereas their MHC class II (MHC-II) expression and function as antigen-presenting cells are matters of considerable controversy. Here we revisited the MHC-II expression on basophils and explored its functional relevance in Th2 cell differentiation...

Nickel is the most frequent allergen in patients with allergic contact dermatitis and nickel allergy has been associated with recurrent in-stent restenosis. However, it is often misdiagnosed because of a low suspicion threshold. It should be discarded in patients with recurrent in-stent restenosis, especially if their medical history reveals prior contact dermatitis. It is also noteworthy and rarely specified that even newer generation stents that use novel metal alloys also contain low amounts of nickel. To avoid the implantation of new stents containing this metal, when percutaneous coronary intervention is indicated, drug eluting balloons or bioresorbable vascular scaffolds associated with small doses of steroids could provide good alternatives of treatment...

4-Hydroxybenzoate is a phenolic derivative of alkyl benzoates and is a widely used preservative in cosmetic and pharmaceutical products. The presence of 4-hydroxybenzoates in the human body may result from the use of pharmaceutical and personal care products. These compounds are also known to exhibit estrogenic and genotoxic activities. The potential adverse effects of these compounds include endocrine disruption, oxidative and DNA damage, contact dermatitis, and allergic reactions. This study used two mass spectrometry methods that are applicable when using a derivatization-enhanced detection strategy (DEDS) to screen 4-hydroxybenzoates and their metabolites...

BACKGROUND: miRNAs are a class of noncoding RNA molecules that modulate gene expression after transcription. It is known that miRNAs are involved in various cellular processes of both normal and diseased skin. Recently, differential expressions of miRNAs have been reported and associated with several immunologic and inflammatory disorders, which indicate a common role in fundamental biologic processes. OBJECTIVE: To collect and review data from the literature on involvement of miRNA in inflammatory skin disorders...

INTRODUCTION: Allergic contact dermatitis is an important cause of hand eczema. Patch testing is the only investigation available to prove the diagnosis of allergic contact dermatitis. Exposures to allergens differ according to geographical, occupational, economic and social factors. Accordingly, patterns of allergic contact dermatitis differ in different parts of the world and different regions of the same country. AIM: To study the causes of allergic contact dermatitis in adult patients with hand eczema with the help of patch testing...

BACKGROUND: The use of methylisothiazolinone (MI) in cosmetic products has caused an unprecedented epidemic of MI contact allergy. Current data concerning exposures at a European level are required. OBJECTIVES: To describe demographics and MI exposures for European patients with MI contact allergy. METHODS: Eleven European dermatology departments from eight European countries prospectively collected data between 1 May and 31 October 2015 among consecutive patients who had positive patch test reactions to MI (2000 ppm aq...

OBJECTIVES: Surgical site complications following great saphenous vein (GSV) harvest presents a significant risk of morbidity. Negative pressure wound therapy (NPWT) has shown promise in the treatment and prophylaxis of open wounds and surgical incisions but has not been studied following GSV harvest. We performed a feasibility study examining the use of NPWT following GSV harvest for coronary bypass surgery. METHODS: Sixty-four patients were recruited in this single-centre, single-blind, randomized controlled trial...

JiaDe Yu, James Treat, Bruce Brod
BACKGROUND: Allergic perineal dermatitis (PD) due to diaper wipes, topical medicaments, or diapers has been reported. Although patch testing is the criterion standard for detection of allergic contact dermatitis in children, this is limited by body surface area, decreased tolerance of the patch testing procedure, and increased false-positive rates due to irritant reactions. Therefore, a targeted patch testing series is necessary to better screen diapered infants for possible allergic PD...

BACKGROUND: Although there are several case reports of wet wipe-associated contact dermatitis, the prevalence of wipes as a source of allergic contact dermatitis in larger populations and the responsible allergens are largely unknown. OBJECTIVE: The aim of the study was to determine the prevalence of wet wipes as a source of contact allergy and the most commonly associated allergens in a North American tertiary referral patch test population. METHODS: Data collected from 2011 to 2014 by the North American Contact Dermatitis Group was used to conduct a retrospective cross-sectional analysis of patient demographics and patch test results associated with the triple-digit source code for "wet wipe...

BACKGROUND: Patch testing is the gold standard for diagnosing allergic contact dermatitis in children. OBJECTIVE: To present a 10-year retrospective review of pediatric patch testing at our institution. METHODS: Data from patients 18 years or younger who presented for patch testing from February 1, 2005, to May 31, 2015, were entered into a database. Patch testing was performed according to North American Contact Dermatitis Group standards...
