The inter-relationship between the perception of bronchoconstriction, bronchial hyper-responsiveness and temporal adaptation in asthma is still a matter of debate. In a total of 52 stable asthmatic patients, 32 without airway obstruction ¿forced expiratory volume in 1 s (FEV(1))/vital capacity (VC) 84.1% (S.D. 7.9%), and 20 with airway obstruction [FEV(1)/VC 60% (4%)], we assessed the perceptio...
Pseudomembranous necrotizing bronchial aspergillosis (PNBA) is a rare form of invasive aspergillosis with a very poor prognosis. The symptoms are non-specific, and the necrotizing plugs cause airway obstruction. Atelectasis and respiratory failure can be the initial manifestations. Recently, we treated an immunocompromised patient with PNBA, who presented with a sudden onset of atelectasis and ...
BACKGROUND Assessing bronchial hyper-responsiveness (BHR) is a main diagnostic criterion of asthma. Provocation testing is not readily available in general practice, but peak expiratory flow (PEF) is. Several guidelines promote the use of PEF variability as a diagnostic tool for BHR. This study tested the agreement between histamine challenge testing and PEF variability, and the consequences fo...
Hyperinflation or atelectasis of a lung or one of its lobes is generally due to partial or complete bronchial obstruction. Intramural large airway obstructive lesions or cysts are uncommon in the pediatric age group. They are usually discovered in the supraglottic or glottic areas. Primary pulmonary, tracheal, or bronchial tumors are very unusual in children. In this report, we describe an infa...
