A 28-year-old man developed multiple episodes of fever, cough, shortness of breath, and leukocytosis several hours after cutting live oak and maple trees. Fungal cultures of wood chips from oak and maple trees were positive for Penicillium (three species), Paecilomyces sp., Aspergillus niger,

BACKGROUND Oak bark has been used since ancient times in Europaen ethnomedicine because of its adstringent, antimicrobial and hemostatic features, e.g. as a remedy for the treatment of wounds and skin diseases. OBJECTIVE Oak bark tannins are considered as bioactive natural products, interacting with

OBJECTIVE To evaluate the response of patients who underwent both skin and in vitro allergy testing, both of which are accepted methods. METHODS Retrospective review of the case notes of 100 patients evaluated by both testing methods for allergic disease. CONCLUSIONS A total of 62 patients (62%)

Sensitization to Quercus ilex (holm oak) was studied in 760 patients with clinically suspected sensitization to aeroallergens. Prick tests with commercial extracts of Q. ilex proved positive in 27 patients; none were monosensitive. Nasal and conjunctival provocation tests and specific IgE (RAST)

OBJECTIVE In traditional Thai medicine, nutgall of Quercus infectoria G. Olivier is well-documented as an effective agent for wound and skin infections. The present study was aimed to establish modes of action of the ethanol extract of the plant as well as its main constituents to induce

BACKGROUND Castanea sativa pollen allergy has generally been considered to be uncommon and clinically insignificant. In our geographical area (Plasencia, Cáceres, Spain) Castanea sativa pollen is a major pollen. OBJECTIVE To determine the atmospheric fluctuations and prevalence of patients

The Bordeles School of Le Coulant described in 1966, a contact dermatitis produced by "hepatics" of the Frullania genus. The hepatics together with the mosses and sphagnus form the group of Bryophytes. Only the hepatics with leaves or Jungermaniales have a capacity to cause sensitivity. They grow in

BACKGROUND A patient experienced an anaphylactic reaction after eating acorn nuts, fruit of the holm oak (Quercus ilex), one of the most abundant trees in Spain. Several urticaria episodes upon ingestion of peanuts were also referred. OBJECTIVE To assess the hypersensitivity reaction to acorn and to

Knowing the beginning of the pollen season is of particular importance to people allergic to a given pollen. Phenological studies in combination with aerobiological studies enable us to observe the relationship between the reproductive phenology of the species and their airborne pollen curves. They

BACKGROUND The allergic response in susceptible patients does not always coincide with the presence and magnitude of airborne pollen counts. The prevalence of allergy to Platanus is currently moderate, although the percentage of monosensitized patients is low. This hinders accurate interpretation of

Climatic change is expected to affect the spatiotemporal patterns of airborne allergenic pollen, which has been found to act synergistically with common air pollutants, such as ozone, to cause allergic airway disease (AAD). Observed airborne pollen data from six stations from 1994 to 2011 at Fargo

Pollen allergies have a remarkable clinical impact all over world. Quercus pollen is the main allergen in many parts of world. Due to the health impacts caused by exposure to oak pollen, the objectives of this study are to characterise the aerobiological behaviour of Quercus pollen and to determine

This study examined whether commercially available conventional and standardized allergen extracts differ enough in potency to affect routine prick skin test results. Extracts of white oak, timothy, Bermuda, Russian thistle, short ragweed, sagebrush, Alternaria, and cat dander were examined in

BACKGROUND Aerobiological studies of interest to the allergy specialist are routinely carried out using information from outdoor traps. However, most of our time is spent indoors and it is often the content of this air that is responsible for allergic phenomena. METHODS The air of a hospital
