BACKGROUND Food allergy (FA) is an important health problem for which epidemiologic studies are needed. OBJECTIVE We performed an epidemiologic survey in France to determine the prevalence, clinical pictures, allergens, and risk factors of FA. METHODS This study was conducted on 33,110 persons who answered a questionnaire addressed to a representative(More)
BACKGROUND Peanut allergy is common, but cross-allergy between legumes is rare. Proteins from Lupinus albus are increasingly eaten in the form of seeds or additives to wheat flour. The risk of cross-allergenicity is still insufficiently known. OBJECTIVE We sought to study the risk of cross-allergy to lupine in patients allergic to peanut and to study(More)
Severe anaphylaxis is a systemic reaction affecting two or more organs or systems and is due to the release of active mediators from mast cells and basophils. A four-grade classification routinely places 'severe' anaphylaxis in grades 3 and 4 (death could be graded as grade 5). Studies are underway to determine the prevalence of severe and lethal(More)
BACKGROUND The prevalence of food anaphylaxis due to masked allergens has increased within the last 10 years. Contamination of manufactured products by food allergens is a key concern for food industries. OBJECTIVE To determine quantities eliciting reactions in patients who have an IgE-dependent food allergy, thanks to standardized oral provocation tests.(More)
Food allergy to cow's milk proteins (APLV) is frequently found in young infants. Treatment is by starting an elimination diet. Different substitution products have been proposed: soya milk, partial hydrolysate of the proteins of lactoserum, powdered casein hydrolysate, hydrolysed soya and pork collagen. Allergic reactions to soya milk, hydrolysates of(More)
BACKGROUND Children with severe food allergies can benefit from a personalized care project (PCP) in schools. The usefulness of the PCP and the residual risk of allergic emergencies are poorly appreciated. The objective was to evaluate the efficiency of the management plan and the training in the use of the emergency kit. METHODS A telephone survey using(More)
Multiple food intolerance in infants and young children is increasingly diagnosed. More than 40% of infants less than 1 y.o. could be affected. The syndrome is characterized by the seriousness of atopic dermatitis (SCORAD > 50), by enterocolitis or failure to thrive or various associations of symptoms that may change over time. The evolution is(More)
In contrast with work-related allergies amongst dentists and dental prosthetictists, allergies in patients followed in orthodontics concerning the materials placed in the mouth were rare. It may be a question of limited manifestations in the buccal cavity (urticaria, angio-oedema, stomatitis, chellitis), or more generalised manifestations (Quincke's oedema,(More)
