BACKGROUND: Sleep is impaired in allergic rhinitis (AR) patients, with subsequent effects on daytime performance and health-related quality of life (QOL). Sleep quality in AR has rarely been considered through validated tools and consensus classifications.

OBJECTIVE: To evaluate sleep quality and daytime somnolence in AR patients, and to estimate its relationship to disease severity according to Allergic Rhinitis and Its Impact on Asthma (ARIA) conventional and modified classifications, ...

BACKGROUND: Eggs are among the foods most frequently causing allergy. Hen eggs are the most important. Those of other birds are of lesser significance.

OBJECTIVE: We report an unusual case of food allergy after consumption of eggs from duck and goose in an adult patient without hen egg allergy.

METHODS: Skin prick tests were performed with fresh white and yolk from eggs of duck and goose and egg white, egg yolk, ovalbumin, and ovomucoid from hen egg. Specific serum IgE was measured to ...

BACKGROUND: Garlic dust has not been a frequently encountered cause of IgE-mediated disease.

OBJECTIVE: We report on 12 patients (all of them garlic workers) with the clinical criteria for occupational asthma.

METHODS: Skin prick tests and serum-specific IgE determinations were performed with common inhalants, garlic, and other members of the Liliaceae family (onion, leek, and asparagus). Bronchial challenge test with garlic powder was performed in all patients. Garlic and onion extract ...

It has been suggested that patients with allergic rhinitis who present nonspecific bronchial hyperresponsiveness (BHR) are those most likely to develop asthma. Therefore, a study was conducted in children with rhinoconjunctivitis to ascertain whether BHR to methacholine might predict the development of asthma in these patients. Fifteen patients with hay fever and no previous symptoms of asthma were selected. All underwent clinical symptom tests and methacholine tests, during the pollen ...

OBJECTIVE: To report a case of immediate rhinoconjunctivitis induced by both metamizole and metronidazole.

METHODS: Skin-tests (prick and intradermal) were performed with metamizole, metronidazole, and espyramicine. Standard RAST was carried out with metamizole and metronidazole. Oral challenge tests were performed single blind with Rhodogil, metronidazole, espyramicine, metamizole, aspirin, and propyfenazone.

RESULTS: Both skin tests and RAST were negative. We also found that the ...

Anisakis simplex is a fish parasite that causes acute or chronic disease in humans after ingestion of raw or undercooked parasitized fish.1 However, in recent years hypersensitivity reactions after the ingestion of parasitized fish have been described, mainly urticaria angioedema or even severe anaphylaxis.2,3We report a patient with perennial conjunctivitis in whom a sensitization to A simplex was demonstrated to be the etiologic factor. This article also examines the possibility that A ...

Sulfites have been implicated as the cause of bronchospasm in some subjects with asthma. However, there is still no universally accepted explanation of the pathogenesis of these reactions. We have studied five children with asthma with metabisulfite intolerance confirmed by oral challenge testing. The challenge test with metabisulfite was repeated after premedication of all the patients with 1.5 mg of oral cyanocobalamin. In four of the five patients treated with cyanocobalamin, ...
