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: DC-SIGN (dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin) is a C-type lectin receptor expressed on macrophages and dendritic cells. DC-SIGN has high affinity for fucosylated glycans in several plant glycoproteins and pathogens. DC-SIGN is thought to be crucial for the development of allergic sensitization. However, the precise role of DC-SIGN in food allergy pathogenesis is not yet understood. OBJECTIVE: We sought to characterize DC-SIGN-binding glycoproteins in a panel of allergenic and non-allergenic foods...

Pine nut is a nutrient-rich food with a beneficial impact on human health. The many bioactive constituents of pine nut interact synergistically to affect human physiology in a favorable way. However, pine nut can trigger dangerous allergic reactions. Severe anaphylactic reactions to pine nut accounted for most of the 45 cases reported in the scientific literature. Pine nut allergy seems to be characterized by low IgE cross-reactivity with other commonly consumed nuts and a high monosensitization rate. The present review provides updated information on allergic reactions to pine nut, molecular characterization of its allergens, and potential homologies with other nut allergens...

BACKGROUND: B cells play a central role in IgE-mediated allergies. In damaged airway epithelium, they are exposed directly to aeroallergens. We aimed to assess whether direct exposure of B cells to pollen constituents affects allergic sensitization. METHODS: B cells from murine splenocytes and from blood samples of healthy donors were incubated for 8 days under Th2-like conditions with aqueous ragweed pollen extracts (Amb-APE) or its constituents. Secreted total IgM, IgG, and IgE was quantified by ELISA...

Olive (Olea europaea) pollen constitutes one of the most important allergen sources in the Mediterranean countries and some areas of the United States, South Africa, and Australia. Recently, we provided evidence that olive pollen releases nanovesicles of respirable size, named generically pollensomes, during in vitro germination. Olive pollensomes contain allergens, such as Ole e 1, Ole e 11, and Ole e 12, suggesting a possible role in allergy. The aim of this study was to assess the contribution of pollensomes to the allergic reaction...

Despite its relatively common occurrence and life-threatening potential, the management of angioedema in the emergency department (ED) is lacking in terms of a structured approach. It is paramount to distinguish the different etiologies of angioedema from one another and more specifically differentiate histaminergic-mediated angioedema from bradykinin-mediated angioedema, especially in lieu of the more novel treatments that have recently become available for bradykinin-mediated angioedema. With this background in mind, this consensus parameter for the evaluation and management of angioedema attempts to provide a working framework for emergency physicians (EPs) in approaching the patient with angioedema in terms of diagnosis and management in the ED...

The prevalence of food allergy has increased in recent years, and Korean pine vicilin is a potential food allergen. We have previously reported the crystallization of Korean pine vicilin purified from raw pine nut. Here we report the isolation of vicilin mRNA and the crystal structure of Korean pine vicilin at 2.40 Å resolution. The overall structure of pine nut vicilin is similar to the structures of other 7S seed storage proteins and consists of an N-terminal domain and a C-terminal domain. Each assumes a cupin fold, and they are symmetrically related about a pseudodyad axis...

Background: The prevalence of IgE reactivity against genuine walnut and hazelnut allergens  is poorly defined. Objective: The IgE response to walnut and hazelnut was investigated in Italian patients with primary allergy to these nuts. Methods: Sera from 36 patients allergic to hazelnut and/or walnut, not reactive to PR-10, profilin, and LTP, underwent immunoblot analysis with extracts of both nuts. Results: Most patients had a history of systemic symptoms following the ingestion of the offending food(s). Twelve patients were sensitized to both walnut and hazelnut, and  13 were sensitized to other nuts and seeds  (cashew, peanut, sesame, pine nut, almond, Brazil nut, and pistachio)...

Pine processionary moth (Thaumetopoea pityocampa) is a lepidopteran living in the Mediterranean countries whose mature larvae have microscopic hairs that can be released and carried far from the source. The hairs are responsible of urticating symptoms on the exposed areas although systemic manifestation might be involved. The study involved 94 forestry workers (92 M, 2 F) of the Regional Forest Service of Verona and the objective was to determine the prevalence of skin and respiratory disorders due to exposure to this insect...

The common cypress (Cupressus sempervirens) (Cups) pollen represents the first cause of respiratory allergies in the Mediterranean basin. The aim of this study was to characterize a novel 14-kDa cypress pollen allergen (BP14) allowing a clear dissociation of IgE sensitization patterns among allergic patients. The biochemical and immunochemical characterization of BP14 included determination of its isoelectric point, molecular mass, extraction kinetics, IgE binding prevalence, the presence of bromelain-type cross-reactive carbohydrate determinant and its IgE reactivity under reducing conditions...

Allergic reactions to wood dust allergens are rare, and only few in vitro diagnostic tools and information about relevant allergens are available. To differentiate between protein-based allergy and probably clinically silent glycogenic sensitization, it is helpful to characterize the relevant protein allergens and specify IgE binding. The current case report deals with the occupational softwood allergy of a carpenter exposed to different wood dusts. Skin tests and IgE tests against wood were performed with specifically tailored ImmunoCAPs and cross-reactive carbohydrate determinants...
