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...

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...

A 33-year-old woman presented to our clinic for suspected photoallergic contact dermatitis with a recent episode of severe, vesicular dermatitis involving exposed skin and correlating with relocation to a new home. Biopsy results showed spongiotic and lichenoid dermatitis with eosinophils. Patch test results showed a very strong (+++) reaction to methylisothiazolinone (MI), mild (+) reaction to MI/methylchloroisothiazolinone, and no reaction to benzisothiazolinone. These allergens were found in several personal products...

BACKGROUND: Patch-test readings after day 5 have previously been used to identify delayed reactions to metals and topical antibiotics. OBJECTIVE: The aims of this study were to identify allergens for which late readings (beyond day 5) would be most valuable and to compare our results with our previous study on delayed patch-test readings. METHODS: This was a retrospective study of 298 patients who underwent metal and corticosteroid series patch testing from January 1, 2007, through December 31, 2013...

Ingredients found in the nail cosmetic industry, including but not limited to methacrylate and acrylate monomers, formaldehyde, and toluene sulfonamide-formaldehyde resin, can incite allergic contact dermatitis. An eczematous outbreak presents on areas surrounding the nail plate and may spread through contact transfer of the allergen, commonly to the face and neck. Even components that were originally deemed nonsensitizing, such as the ubiquitous cyanoacrylate adhesive family, have been found to be allergenic...

Complex immunologic pathways, influenced by both genetic and environment triggers, contribute to the development of atopic dermatitis and allergic contact dermatitis. Suppressing mechanisms between the Th1-driven allergic contact dermatitis and the Th2-driven atopic dermatitis conditions were thought to reduce the simultaneous expression of both; however, recent evidence indicates that pediatric patients with atopic dermatitis are likely to develop clinically relevant positive patch tests and more likely to react to specific allergens, such as lanolin...

BACKGROUND: Nickel (Ni) is widely distributed in the environment and continuous exposure to this metal may lead to pathological manifestations, such as the human allergic contact dermatitis. METHODS: The in vitro effects of Ni on human healthy non allergic peripheral blood mononuclear cells (PBMCs) in the absence or presence of red grape polyphenols have been evaluated. In the culture supernatants, levels of cytokines have been determined by ELISA, while nitric oxide (NO) concentration has been evaluated by a colorimetric procedure...

A 68-year-old woman, with a 75-pack-year smoking history and a history of chronic excess alcohol intake, presented with a 5-week history of worsening perianal pain and ulceration. She recently had an inpatient admission with back pain and urinary tract infection during which she developed diarrhea and fecal incontinence. Initially, the perianal ulceration was diagnosed as severe irritant contact dermatitis and treated with barrier creams and topical clobetasone 17-butyrate 0.05% weight for weight, oxytetracycline 3...

Itch, a sensation eliciting a desire to scratch, is distinct from but not completely independent of pain. Inspiring achievements have been made in the characterization of itch-related receptors and neurotransmitters, but the molecular mechanisms controlling the development of pruriceptors remain poorly understood. Here, our RNAseq and in situ hybridization data show that the transcription factor Tlx3 is required for the expression of a majority of itch-related molecules in the dorsal root ganglion (DRG). As a result, Tlx3(F/F);Nav1...

BACKGROUND: Alopecia areata is a non-scarring hair loss, which typically starts quickly. Atopy is one of the possible predisposing risk factors for this condition. AIM: This study aimed to evaluate the prevalence of thyroid disease, atopic dermatitis and allergic diseases in children with alopecia areata and compare the results with healthy individuals. METHODS: This case-control study was conducted on 50 patients with alopecia areata, diagnosed by a dermatologist, and 150 healthy individuals as the control group...

OBJECTIVES: The aim of this study was to investigate the effects of formaldehyde exposure on Th17 and Th22 cells and its relevance to human occupational allergic contact dermatitis (OACD). METHODS: Circulating IL17-/IL22-secreting cells and serum IL17/IL22 levels in formaldehyde-exposed workers at Occupational Exposure Limit and nonexposed controls were assessed. RESULTS: The IL17 and IL22 cell population were detected in both CD3CD8 and CD3CD8 cells...

In East Asia, herbs are not only used by traditional medical practitioners but also commonly eaten by public. Compositae and Rhus are well-known antigens that can cause allergic contact dermatitis, but the other herbs are not well studied for antigenicity. Hosta plantaginea (also known as 'August lily' or 'Plantain lily') is originated from China and usually grown for ornamental purposes (Fig. 1a~c). In traditional medicine, flowers are used as oral medicines for sore throat or dysuria and sometimes topically applied for burn...

According to Coombs and Gell, cell-mediated immune responses belong to type IV reactions and are borne mainly by T lymphocytes. The eliciting allergens are usually so-called haptens. Haptens are substances which develop to whole antigens only by binding to protein carriers. In otorhinolaryngology, delayed allergic hypersensitivities are apparent mainly as contact eczemata. Facial dermatitis, auricle and ear canal eczema as well as perioral eczema belong to the most common forms of contact dermatitis in ENT patients...

Allergic contact dermatitis (ACD) is a common T-cell mediated inflammatory skin condition, characterized by an intensely pruritic rash at the site of contact with allergens like poison ivy or nickel. Current clinical treatments use topical corticosteroids, which broadly and transiently suppress inflammation and symptoms of ACD, but fail to address the underlying immune dysfunction. Here, we present an alternative therapeutic approach that teaches the immune system to tolerate contact allergens by expanding populations of naturally suppressive allergen-specific regulatory T cells (Tregs)...
