Forty patients with symptomatic immediate hypersensitvity to egg who did not have atopic dermatitis were evaluated to determine if they continued to remain clinically symptomatic. Each had specific IgE in vitro and positive prick-test to egg. All patients were on an egg elimination diet. During the follow-up an open egg rechallenge was performed along with(More)
Goji berries (GB) have been introduced in Western diet. Preliminary reports have demonstrated its allergenic capacity. The objectives of the study were to investigate the frequency of sensitisation and the allergens involved. 566 individuals, with respiratory or cutaneous symptoms were skin-prick tested with GB extract. Thirty three were positive (5.8%).(More)
BACKGROUND Tomatoes (Lycopersicon esculentum) are consumed world-wide. The prevalence of sensitization to tomatoes remains unknown. OBJECTIVE To determine the prevalence of skin test reactivity to tomato and to describe the characteristics of tomato-sensitized subjects. METHODS Individuals attending for the first time during the period of the study to(More)
BACKGROUND Although allergy to Cannabis sativa was first reported over 40 years ago, the allergenicity has scarcely been studied. The objectives of this study were to investigate the frequency of sensitization to this plant, to analyze the clinical characteristics and allergenic profile of sensitized individuals and to identify the allergens involved.

BACKGROUND Cases of allergy to Cannabis sativa have occasionally been reported, but both the allergenic profile and eventual cross-reactivity pattern remain unknown. OBJECTIVE To analyze the allergenic profile of a population of patients from Spain sensitized to C. sativa and to characterize the C. sativa leaf extract. METHODS A total of 32 subjects(More)
BACKGROUND The efficacy of allergen immunotherapy using depigmented and polymerized extracts has been previously shown for Olea europaea, Phleum pratense, and Parietaria judaica. The objective of this study was to evaluate the efficacy after 3 and 6 months of treatment of a depigmented, polymerized extract of a mixture of Dermatophagoides pteronyssinus and(More)
BACKGROUND The prevalence of sensitization to tomato has been estimated in 6.5% in a Mediterranean population. OBJECTIVES To characterize the allergenic profile of 6 commonly ingested varieties of tomato and to identify and quantify the most representative allergens. METHODS Rama, Rambo, Canario, Kumato, Pera and Raf tomato varieties were carefully(More)
Three tomato allergens (Lyc e 1, Lyc e 2 and Lyc e 3) have been characterised until now. Previous studies have demonstrated the existence of other proteins with capacity to bind IgE. The objective of this study was to identify new tomato allergens by molecular biology techniques. A tomato peel cDNA library was screened using a specific pool of sera from(More)
The inhalation of wood dust may produce allergic rhinitis, asthma, or contact dermatitis in sensitized patients. We describe a patient with occupational asthma induced by the inhalation of samba (Triplochiton scleroxylon) wood dust. A specific bronchial provocation test was conducted, and the patient showed a significant decrease in forced-expiratory volume(More)
