REVIEW
Jonathan S Tam
Hypersensitivity reactions to foods can have diverse and highly variable manifestations. Cutaneous reactions, such as acute urticaria and angioedema, are among the most common manifestations of food allergy. However, cutaneous manifestations of food allergy encompass more than just IgE-mediated processes and include atopic dermatitis, contact dermatitis, and even dermatitis herpetiformis. These cutaneous manifestations provide an opportunity to better understand the diversity of adverse immunologic responses to food and the interconnected pathways that produce them...

Several epidemiological studies have suggested a possible link between exposure to Diisononyl phthalate (DINP) and the development of allergies. These findings remain controversial since there is insufficient scientific evidence to assess the ability of DINP to influence allergic immune responses. In addition, the mechanisms behind DINP-caused allergic diseases have not been fully elucidated. In this study, Balb/c mice were orally exposed to DINP for 3 weeks and were then sensitized with fluorescein isothiocyanate (FITC)...

BACKGROUND: For more than 30 years, fragrance mix I (FMI) has been the most important screening marker for fragrance contact allergy. Meanwhile, governmental and corporate initiatives have been implemented, aimed at reducing sensitization to fragrance allergens, including the single constituents of FMI. OBJECTIVES: To examine trends in contact allergy to FMI from 1986 to 2015 in dermatitis patients, and test the hypothesis that sensitization to the fragrance screening marker has decreased within recent years...

OBJECTIVE: Takotsubo syndrome (TS) is a heart condition characterised by a sudden transient left ventricular dysfunction; its pathophysiology is probably associated with elevated levels of catecholamines but the exact mechanism is not known as yet. Literature and clinical experience suggest that TS affects persons with various comorbidities. This pilot work aims to evaluate the frequency of comorbidities with potential pathological immune reactivity, and to evaluate the potential association between TS and hypersensitivity to metals assessed by LTT-MELISA®...

Poison ivy-induced allergic contact dermatitis (ACD) is the most common environmental allergic condition in the United States. Case numbers of poison ivy ACD are increasing due to growing biomass and geographical expansion of poison ivy and increasing content of the allergen, urushiol, likely attributable to rising atmospheric CO2 Severe and treatment-resistant itch is the major complaint of affected patients. However, because of limited clinical data and poorly characterized models, the pruritic mechanisms in poison ivy ACD remain unknown...

Inflammatory scalp dermatoses can be associated with alopecia, which is nonscarring and reversible in its early stages. This association has been described in seborrheic dermatitis, psoriasis, and atopic dermatitis. We describe three girls with alopecia aggravated by contact allergy to balsam fragrances. All three had complete resolution with avoidance of balsam of Peru and other balsam derivatives (including discontinuation of fluocinolone oil, which contains balsam of pine).

BACKGROUND: Allergic contact dermatitis after exposure to p-phenylenediamine (PPD)-containing hair dye products is a common and important clinical problem. Because there is a high rate of cross-elicitation of allergic contact dermatitis to other important hair dye products (such as p-toluene diamine and other aminophenol hair dyes) in PPD-allergic patients, safer alternative dyes with excellent hair coloring options are needed. OBJECTIVE: This study aimed to study tolerance to Me-PPD in a PPD-allergic cohort...

Systemic hypersensitivity (HS) to corticosteroids (CS) is paradoxical but does exist. Some patients with a previous contact allergy to topical CS may develop a systemic contact dermatitis (SCD) while receiving CS orally or intravenously. However, a previous contact sensitization is not mandatory for developing a systemic HS to CS. Acute or delayed urticaria can occur in immediate HS. Immediate HS can be due to excipients, mainly carboxymethylcellulose or to CS themselves. Delayed reactions, mainly maculopapular rash and acute generalized exanthematous pustulosis can occur...

BACKGROUND: Five workers from a plant manufacturing concrete wall panels and beams were referred to our department because of suspected occupational dermatitis. When patch tested, 3 workers reacted to potassium dichromate. Four workers reacted to ethylenediamine dihydrochloride, without any obvious exposure. Owing to the high proportion of workers with recent-onset skin disease, an investigation of all workers at the plant was initiated. OBJECTIVES: To investigate the prevalence of occupational dermatitis and contact allergy in the workers at the plant...

INTRODUCTION AND OBJECTIVES: Due to its inert character and desired biocompatibility, titanium (Ti) implants have been universally accepted as safer alternatives to the previous conventional orthopedic hardware implants. However, a recent emergence of Type IV hypersensitivity reactions to Ti have displayed symptoms that include eczema, contact dermatitis, prolonged fever, sterile osteomyelitis, and impaired fracture and wound healing. The following case presents a patient with postoperative incision dehiscence and devascularization of cortical surfaces in contact with Ti hardware after undergoing a medial displacement calcaneal osteotomy and a first metatarsal-cuneiform arthrodesis...

BACKGROUND: Nickel is the most common allergen found by patch testing; however, not all cases of nickel allergy are type 4 (delayed) allergies. Contact urticaria (CU) to nickel (immediate reaction) has been reported; however, few seem to evaluate it as per a recent published survey of American Contact Dermatitis Society members. OBJECTIVE: The aim of the study was to present a series of patients who had clinical histories suggestive of nickel allergy and yet were patch test negative but prick test positive to nickel, thus demonstrating CU...

Patients with atopic dermatitis have skin barrier impairment in both lesional and non-lesional skin. They are typically exposed to emollients daily and topical anti-inflammatory medicaments intermittently, hereby increasing the risk of developing contact allergy and systemic exposed to chemicals ingredients found in these topical preparations. We systematically searched for studies that investigated skin absorption of various penetrants, including medicaments, in atopic dermatitis patients, but also animals with experimentally induced dermatitis...

OBJECTIVE: Contact allergies can occur frequently in patients with chronic leg ulcers (CLUs), even in those with a short duration of ulcerative disease. The wide spectrum of therapeutic products promotes development of the delayed type of hypersensitivity and continuous changes in the allergens pattern, which make the diagnosis and treatment extremely difficult in many cases. A prompt diagnosis and treatment of allergic contact dermatitis (ACD) in patients suffering from CLUs is very important for a best clinical outcome of these two common diseases...

The International Contact Dermatitis Research Group proposes a classification for the clinical presentation of contact allergy. The classification is based primarily on the mode of clinical presentation. The categories are direct exposure/contact dermatitis, mimicking or exacerbation of preexisting eczema, multifactorial dermatitis including allergic contact dermatitis, by proxy, mimicking angioedema, airborne contact dermatitis, photo-induced contact dermatitis, systemic contact dermatitis, noneczematous contact dermatitis, contact urticaria, protein contact dermatitis, respiratory/mucosal symptoms, oral contact dermatitis, erythroderma/exfoliative dermatitis, minor forms of presentation, and extracutaneous manifestations...

BACKGROUND: In the contact dermatitis literature, it is regularly stated that the patch test reactivity on various areas of the back differs; this might have a large impact on the reproducibility of patch testing. OBJECTIVES: To investigate the reproducibility of patch testing on the upper back with regard to the left as opposed to the right side and the medial as opposed to the lateral part of the upper back. The reproducibility over time and with regard to the reactivity pattern was also investigated...
