Sawmill workers are exposed to wood dust (a well-known carcinogen), microorganisms, endotoxins, resin acids (diterpenes), and vapours containing terpenes, which may cause skin irritation, allergy, and respiratory symptoms including asthma. The health effects of most of these exposures are poorly understood as most studies measure only wood dust. The present study assessed these exposures in the Norwegian sawmill industry, which processes predominantly spruce and pine. Personal exposures of wood dust, resin acids, endotoxin, fungal spores and fragments, mono-, and sesquiterpenes were measured in 10 departments in 11 saw and planer mills...

There is currently no cure for food allergies, and sufferers can only rely on the correct labeling of foods to avoid allergens. Hence, it is important that analytical methods are sensitive and accurate enough to screen for the presence of multiple allergens in food products. In this study, we developed an LC-tandem MS method that is able to simultaneously screen or quantify the signature tryptic peptides of multiple allergen commodities. This method is capable of screening and identifying egg white, skim milk, peanut, soy, and tree nuts (almond, Brazil nut, cashew, hazelnut, pecan, pine nut, pistachio, and walnut) at a detection limit of 10 ppm in incurred bread and cookies...

Allergenic pollen is produced by the flowers of a number of trees, grasses and weeds found throughout the UK. Exposure to such pollen grains can exacerbate pollen-related asthma and allergenic conditions such as allergic rhinitis (hay fever). Maps showing the location of these allergenic taxa have many applications: they can be used to provide advice on risk assessments; combined with health data to inform research on health impacts such as respiratory hospital admissions; combined with weather data to improve pollen forecasting systems; or as inputs to pollen emission models...

Pollen allergy is caused by a hypersensitivity reaction mainly of the respiratory tract and eye conjunctivae to pollen grains. The number of people allergic to plant aeroallergens has substantially increased in big cities and industrial areas. The monitoring of aerobiological parameters is of paramount importance for the characterization of allergenic risks. The aims of presented study were as follows: to profile the plant aeroallergens in two major cities of Georgia, to compare the character of pollination curves, to determine the dates of beginning of pollen seasons and their duration in particular cities...

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...
