Phytophotodermatitis is a condition caused by sequential exposure to photosensitizing substances present in plants followed by ultraviolet light. Several plants (e.g., limes, celery, fig, and wild parsnip) contain furocoumarin compounds (psoralens). It is important for dermatologists to be aware of phytophotodermatitis because it may be misdiagnosed as cellulitis, tinea, or allergic contact dermatitis. We present five patients with a sharply defined erythematous swollen patch with bullae on both feet. They described soaking their feet in a fig leaves decoction to treat their underlying dermatologic diseases...

Chemical hypersensitivity is an immunological response towards foreign substances, commonly referred to as sensitizers, which gives rise primarily to the clinical symptoms known as allergic contact dermatitis. For the purpose of mitigating risks associated with consumer products, chemicals are screened for sensitizing effects. Historically, such predictive screenings have been performed using animal models. However, due to industrial and regulatory demand, animal models for the purpose of sensitization assessment are being replaced by animal-free testing methods, a global trend that is spreading across industries and market segments...

BACKGROUND: Protein contact dermatitis has frequently been reported in case studies (usually in cases involving contact with seafood products), but there are very few descriptive series. The objectives of this present study were firstly to determine the incidence of protein contact dermatitis among fishermen in France and compare it with data from onshore work involving seafood exposure. Second, to discover what factors could explain any differences. In order to answer these questions we analysed data from the French national occupational disease surveillance and prevention network (RNV3P) and occupational diseases declared to the French National Network for Monitoring and Prevention of Occupational Disease...

Skin findings during the initial month of life are ubiquitous. One study estimated that more than 95% of newborns have cutaneous findings, which often are distressing to parents but frequently are benign and self-limited. Among them are milia, cutis marmorata, congenital dermal melanocytosis, and the benign neonatal pustular eruptions (eg, benign cephalic pustulosis, erythema toxicum neonatorum, transient neonatal pustular melanosis). Clinicians need to recognize these benign skin conditions and differentiate them from more serious conditions, such as infectious pustular eruptions from bacterial, viral, and fungal causes, and inflammatory conditions, such as Langerhans cell histiocytosis...

BACKGROUND: Patients with lower leg dermatitis, chronic venous insufficiency or chronic leg ulcers have a high prevalence of contact sensitization. OBJECTIVES: To identify the current spectrum of contact allergens in these patients. PATIENTS AND METHODS: Data of the Information Network of Departments of Dermatology on 5264 patients with the above diagnoses from the years 2003 to 2014 (study group) were compared with data on 4881 corresponding patients from 1994 to 2003 (historical control group) and with a current control group without these diagnoses (n = 55 510)...

The isothiazolinone derivatives, methylchloroisothiazolinone (MCI), methylisothiazolinone (MI), benzisothiazolinone (BIT), and octylisothiazolinone (OIT), owing to their strong bactericide, fungicide and algicide properties, are widely used in non-cosmetic products, such as chemical (industrial) products, household detergents, and water-based paints, and the former two derivatives are also used in cosmetic products. However, given their inherent sensitization potential (with MCI > MI > BIT > OIT), allergic contact dermatitis is frequently observed, both in consumers as well as workers in various industries...

Allergic contact dermatitis related to cosmetic use can result from allergens not routinely evaluated by standard patch test protocols. Propyl, octyl, and dodecyl gallates are commonly used as antioxidant preservatives with reports of associated allergic contact dermatitis in the literature. The objectives of this review were to investigate the role of gallates in allergic contact dermatitis and to explore products containing these preservatives. A systematic review of the literature through April 2016 was performed to explore cases of reported gallate allergy...

Tetradecanol is a straight-chain saturated fatty alcohol purified from Dendropanax morbifera leaves. We found that tetradecanol (30μM) reduced specifically the growth of T cells such as EL-4 T cell and isolated murine CD4(+) T cells. In this study, we investigated the effects of tetradecanol on the regulation of interlukin-2 (IL-2), a potent T cell growth factor. Tetradecanol significantly inhibited IL-2 secretion in EL-4 T cells activated with phorbol 12-myristate 13-acetate (PMA) plus ionomycin (Io) and also in isolated murine CD4(+) T cells activated with anti-CD3 and anti-CD28 antibodies...

BACKGROUND: Ticks attach to and penetrate their hosts' skin and inactivate multiple components of host responses in order to acquire a blood meal. Infestation loads with the cattle tick, Rhipicephalus microplus, are heritable: some breeds carry high loads of reproductively successful ticks, whereas in others, few ticks feed and reproduce efficiently. METHODS: In order to elucidate the mechanisms that result in the different outcomes of infestations with cattle ticks, we examined global gene expression and inflammation induced by tick bites in skins from one resistant and one susceptible breed of cattle that underwent primary infestations with larvae and nymphs of R...

Dear Editor, Erythema multiforme is considered an acute skin condition, characterized by a self-limiting and sometimes recurrent course. It is regarded as a type IV hypersensitivity reaction associated with certain infections, medications, and other various triggers. Allergic contact dermatitis is in turn a delayed type of induced allergy as a result of cutaneous contact with a specific allergen to which the patient develops specific sensitivity. This type of cutaneous reaction is associated with inflammation manifesting with erythema, edema, and vesicles...

Epoxides are known or proposed to be involved in skin sensitization in various ways. Some are encountered directly, and others have been shown to be formed abiotically and metabolically from various unsaturated chemicals. They can react as SN2 electrophiles. To date no quantitative mechanistic models (QMMs) are known for skin sensitization potency of this subcategory of SN2 electrophiles. Here we have considered the reaction mechanistic chemistry of epoxides and combined published experimental kinetic data (rate constants k for reaction with a cysteine-based peptide) together with calculated hydrophobicity data (logP) to derive a QMM correlating potency in the local lymph node assay (LLNA), expressed as EC3, with a relative alkylation index (RAI, calculated as logk + 0...

BACKGROUND/OBJECTIVE: The isothiazolinones methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) are prevalent pediatric contact sensitizers. MI allergic contact dermatitis (ACD) is underreported in the literature. The objective of the current study was to use a database of provider-reported U.S. pediatric patch test cases to evaluate the positive patch test (PPT) prevalence rates of the combined preservative test substrate MCI/MI and of MI alone. METHODS: U...

Various haptens trigger innate immune pathways and/or induce cytotoxicity as a part of sensitization. Adam et al. decipher in vitro the mechanisms by which chromium(VI) induces inflammation, the likely prerequisites for toxicity, sensitization, and allergic contact dermatitis against chromium(VI). Importantly, and in line with other observations, chromium(VI), but not chromium(III) (or Ni(II)), induces mitochondrial reactive oxygen species accumulation. Mitochondrial reactive oxygen species in turn activate the NLRP3 inflammasome, allowing increased IL-1β processing and secretion, which likely underlies both chromium(VI)-induced cutaneous toxicity and sensitization...

Allergic contact dermatitis (ACD) is a common skin condition caused by a type-IV hypersensitivity reaction. Even though ACD is considered as a T-cell mediated disease, indications exists that peptidergic nerve fibers at the site of allergen exposure and associated with the draining lymph node play a prominent role in both induction and elicitation of ACD. This neuro-immune cross talk seems rely on neuropeptides such as Substance P secreted by nerve fiber terminals. It is hypothesized that local complete or partial cutaneous denervation/defunctionalization of peptidergic fibers in humans could be a feasible approach towards treating allergic contact dermatitis...
