Polymorphic light eruption (PLE) is described as a delayed-type hypersensitivity reaction (DTHR) toward a de novo light-induced antigen, yet to be identified. In effect, the inflammatory pathways of PLE and allergic contact dermatitis (ACD) share common patterns in terms of the mediators involved from the innate and adaptive immune system participating in the DTHR. As we have previously highlighted the role of interleukin (IL)-1 family members in ACD, we hypothesised that the same mediators could have similar functions in PLE...

BACKGROUND: While studies have shown that postoperative wound complications can predispose to deep infection following orthopedic surgery, the best form of skin closure has not been elucidated. Furthermore, the unique risks and benefits of each type of wound closure have not been studied. The goal of this study is to present the diagnosis and treatment of patients with allergic contact dermatitis (ACD) from 2-octyl cyanoacrylate, a skin adhesive commonly used in wound closure. METHODS: Twenty-nine patients with ACD to 2-octyl cyanoacrylate (Prineo, Ethicon, NJ) following elective orthopedic surgeries from 2013 to 2016 were retrospectively reviewed; this occurred in 29 of 6088 units of Prineo used at our institution, for an estimated incidence of 0...

BACKGROUND: Chronic itch is a highly debilitating symptom that underlies many medical disorders with no universally effective treatments. Although unique neuronal signaling cascades in the sensory ganglia and spinal cord have been shown to critically promote the pathogenesis of chronic itch, the role of skin-associated cells remains poorly understood. OBJECTIVE: We sought to examine the cutaneous mechanisms underlying transient receptor potential vanilloid 4 (TRPV4)-mediated allergic and nonallergic chronic itch...

BACKGROUND: Glucose sensors, such as FreeStyle® Libre, are innovative medical devices developed for diabetes patients as a replacement for classic glucose meters, ensuring continuous glucose monitoring without the disadvantage of regular skin finger pricks. OBJECTIVES: To report several cases of allergic contact dermatitis caused by FreeStyle® Libre, and to report on isobornyl acrylate as a culprit allergen. PATIENTS AND METHODS: Fifteen patients presented with allergic contact dermatitis caused by FreeStyle® Libre...

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: Ground crew of the Air Force routinely handle aviation turbine fuel (ATF) and lubricants and a need was felt to study the adverse effects of these substances on their skin so that remedial measures could be taken to prevent these adverse effects. METHODS: A multi-centric, cross-sectional, observational study was performed at three Air Force flying stations. 109 ground crew members of the Indian Air Force (IAF) who were in direct contact with ATF and lubricants were screened for dermatological manifestations on exposed areas...

Skin-migratory dendritic cells (migDCs) are pivotal antigen-presenting cells that continuously transport antigens to draining lymph nodes and regulate immune responses. However, identification of migDCs is complicated by the lack of distinguishing markers, and it remains unclear which molecules determine their migratory capacity during inflammation. We show that, in the skin, the neuronal plasticity molecule activity-regulated cytoskeleton-associated protein/activity-regulated gene 3.1 (Arc/Arg3.1) was strictly confined to migDCs...

Skin diseases in the vulvar area include a variety of disorders many of which have a chronic course with significant morbidity. It is important to be aware of the symptoms, signs and diagnostic tools in order to optimise treatment. Herein, the most common eczematous diseases of the vulvar area, i.e. lichen simplex chronicus, seborrhoeic dermatitis, atopic dermatitis, irritant contact dermatitis, and non-systemic and systemic allergic contact dermatitis are reviewed. Allergic contact urticaria is also described...

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: Allergic contact dermatitis (ACD), which is accelerated by interferon (IFN)-γ and suppressed by interleukin (IL)-10 as regulators, is generally self-limited after removal of the contact allergen. Adipose tissue-derived multipotent mesenchymal stem cells (ASCs) potentially exert immunomodulatory effects. Considering that subcutaneous adipose tissue is located close to the site of ACD and includes mesenchymal stem cells (MSCs), the MSCs in adipose tissue could contribute to the self-limiting course of ACD...

The innate immune components that modulate allergic contact hypersensitivity (CHS) responses are poorly defined. Using human skin from contact dermatitis patients and a mouse model of CHS, we find that hapten allergens disrupt the Arginase1 (Arg1) and inducible NO synthase (iNOS) dynamic in monocytes/macrophages (mono/MΦ), which renders those cells ineffectual in suppressing skin inflammation. Mice lacking Arg1 in MΦ develop increased CHS characterized by elevated ear thickening, mono/MΦ-dominated dermal inflammation, and increased iNOS and IL-6 expression compared with control mice...

The skin is an important site for local or systemic application of drugs. However, most of the drugs have poor permeability through the skin's outermost layer, stratum corneum. The aim of this study was to develop a method to enable transdermal delivery of morin (3, 5, 7, 2, 4-pentahydroxyflavone), which is a poorly water-soluble drug with anti-inflammatory properties obtained from natural products. Morin phospholipid complex (MPC) was prepared and then loaded in Carbopol 940 hydrogel (MPC-gel), which can significantly increase the transdermal flux of morin based on the in vitro skin penetration data presented in this paper...

BACKGROUND/OBJECTIVES: Footwear dermatitis is a form of contact dermatitis resulting from exposure to shoes. There have been only small studies regarding foot contact dermatitis in children. The present study was undertaken to define the prevalence and epidemiologic and clinical features of shoe dermatitis in children. METHODS: A retrospective study was undertaken of all children referred for patch testing between 1996 and 2015. Children with dermatitis limited to the feet were selected...
