The potential role of peak nasal inspiratory flow to evaluate active sinonasal inflammation and disease severity.

Although the pathophysiology of nasal polyposis is incompletely understood, rhinologists have seldom studied it with rhinomanometry or peak nasal inspiratory flow (PNIF) due to technical limitations and the perception that polyp size might impair reproducibility and the usefulness of recordings. The objective of this study is to assess how measures of rhinomanometry and PNIF relate to disease activity. Nineteen patients with polyps, 15 patients with chronic sinusitis without polyps and 11 negative controls were evaluated with active anterior rhinomanometry and PNIF.

Recovery of cochlear and vestibular function after labyrinthine haemorrhage.

Inner ear haemorrhage is a rare disorder with disabling symptoms. Prognosis is generally considered to be poor with essentially no chance of functional recovery. The most common aetiologies are related to blood dyscrasias, anticoagulant therapy or local trauma.

Environment and Health in Children Day Care Centres (ENVIRH) - Study rationale and protocol.

Background: Indoor air quality (IAQ) is considered an important determinant of human health. The association between exposure to volatile organic compounds, particulate matter, house dust mite, molds and bacteria in day care centers (DCC) is not completely clear. The aim of this project was to study these effects.

[Reported drug allergy among children attending day care centers].

Introduction: Data about drug allergy prevalence in the general population, particularly in children, are lacking. This study aimed to estimate the prevalence of parent-reported drug allergy, in children attending day care centers in Lisbon and Oporto.

Material And Methods: In Phase II of the "ENVIRH study - Environment and Health in Children Day Care Centers", a health questionnaire which included questions about drug allergies was administered to children by stratified, random sampling of day care centers.
