We present 25 patients, aged between 18 and 153 months, with clinical symptoms suggestive of allergy to food antigens. After undergoing exhaustive studies (including case histories, cutaneous tests for reactions to food antigen, peripheral eosinophils, secretory and humoral immunity, determination of total IgE and of specific RAST, exclusion-provocation(More)
OBJECTIVE To develop and validate a questionnaire to assess asthma control in children (CAN). DESIGN Two versions of the CAN (for carers and children) were developed. Both versions were validated in an observational, prospective, multicenter study performed in 38 hospital outpatient clinics throughout Spain. Four hundred fifteen patients and their carers(More)
BACKGROUND The clinical efficacy of allergen immunotherapy using therapeutic vaccines containing modified allergen extracts has been previously shown. OBJECTIVE To evaluate the clinical efficacy of a vaccine containing depigmented, polymerized extract of Dermatophagoides pteronyssinus in asthmatic children, monosensitized to mites, after 4 months of(More)
Recurrent urticaria and recurrent angioedema are frequent adverse reactions in non-atopic patients who do not tolerate aspirin. Of 1,632 infants and children who visited our allergy department for the first time, nine children (0.55%), five males and four females, presented recurrent urticaria or recurrent angioedema after taking aspirin. No evidence of(More)
Patients who are allergic to latex (Hevea brasiliensis) may exhibit cross-hypersensitivity with foods. We present a case of anaphylaxis due to cassava in a patient suffering from pollinosis, latex allergy, and latex-fruit syndrome. We performed sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting with cassava, avocado,(More)
BACKGROUND Different opinion documents point to a patient age of under five years as a relative contraindication to specific immunotherapy, arguing that this age group has a greater risk of developing anaphylaxis, and that specially trained personnel are needed to deal with the problem if it occurs. However, insufficient evidence exists to support such an(More)
BACKGROUND Good control of allergic rhinitis (AR) in children is desirable because it is associated with diseases such as asthma. The aim of this analysis of the PETRA study was to characterise its diagnosis and treatment in Spanish children. METHODS Data were analysed for paediatric patients (age 5-17 years, inclusive) included in the PETRA study, which(More)
Topical application of antihistamines commonly leads to sensitization for patients, but systemic administration of antihistamines rarely induces allergic hypersensitivity, which is mainly linked to phenothiazine-derived and piperazine-derived compounds. We report a 70-year-old woman whose medical history included lichen planus, and who was referred by the(More)
The data of the ISAAC project in Spain show a prevalence of childhood asthma ranging from 7.1% to 15.3%, with regional differences; a higher prevalence, 22.6% to 35.8%, is described for rhinitis, and atopic dermatitis is found in 4.1% to 7.6% of children. The prevalence of food allergy is 3%. All children in Spain have the right to be visited in the(More)
OBJECTIVE We present two adult and three paediatric patients who had allergic reactions after cheese ingestion and subsequently tolerated cow's milk derivatives. The objective of this study was to determine possible cross-reactivity between different types of cheese. METHODS Skin tests were performed to cow's milk fractions, and prick-prick tests for(More)
