BACKGROUND Anaphylaxis after ingestion of flours contaminated with mites has been recently reported. OBJECTIVE The study was designed to determine whether four-induced reactions in the absence of food sensitivity may result from mite contamination. METHODS Patients with systemic reactions after ingestion of foods containing wheat flour and without food(More)
The T2K experiment observes indications of ν(μ) → ν(e) appearance in data accumulated with 1.43×10(20) protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with |Δm(23)(2)| = 2.4×10(-3)  eV(2), sin(2)2θ(23) = 1 and sin(2)2θ(13) = 0, the expected number of such events is 1.5±0.3(syst).(More)
BACKGROUND Latex IgE-mediated allergy is an important medical problem, but its clinical characteristics and association with food allergies are not well defined. OBJECTIVE Our objectives were to determine the clinical features of latex-allergic patients, and latex-associated food hypersensitivities. METHODS A prospective study was performed in our(More)
Food hypersensitivity (FH) is lesser frequent among adult patients than in childhood. Foods implicated in hypersensitivity reactions vary with sociocultural and diet habits from a geographic place to other. We studied 142 adult patients sensitized to foods, among 7698 patients visited at our Outpatient Clinic. Hundred and twenty patients referred clinical(More)
An extensive clinical study has been performed on pigeon breeders in the Canary Islands. Three hundred forty-three subjects have participated in this study through the filling of a clinical and epidemiologic questionnaire. A venous blood sample was also taken from each fancier for a further serologic analysis. Detection of specific IgG antibodies was made(More)
BACKGROUND Mustard IgE-mediated allergy is supposed to be a rare cause of food allergy, and its clinical features and cross-reactivities have not been fully elucidated. METHODS A prospective study was carried out, recruiting mustard allergic patients, and paired control subjects. A clinical questionnaire was administered, and skin-prick tests (SPT) with(More)
Shellfish is one of the most frequent causes of food allergy. We studied 48 patients (25 male and 23 female) with a mean age of 24.2 +/- 1.8 with shellfish hypersensitivity. A clinical questionnaire was carried out and prick tests were performed using a series of aeroallergens and a battery of extracts of squid, shrimp, lobster, crab, mussel and clam. Prick(More)
The effect of recombinant human erythropoietin (rHuEPO) on primary hemostasis was tested in 19 hemodialyzed patients. Bleeding time, platelet aggregation and platelet interaction with vessel subendothelium (SE) under flow conditions were determined before treatment and after patients reached hematocrits greater than or equal to 30%. Two thrombotic events(More)
The prevalence of hepatitis C virus antibody and its relationship to the severity of liver disease in chronic alcoholic patients has been assessed, using a recently developed enzyme immunoassay and confirmed by a recombinant immunoblot assay, in 144 patients (mean age +/- S.D. = 44.4 +/- 11.3 yr) who had consumed greater than 80 gm/day ethanol for greater(More)
HLA antigens were studied in three different groups of 50 patients each. These included (a) Forestier's disease, (b) ankylosing spondylitis, and (c) polyarthrosis of the hands. HLA typing included 12 specificities from locus A and 15 from locus B, the frequencies being compared to those in 700 normal controls. No significant differences were found in the(More)
