BACKGROUND Small airways are regarded as the elective anatomic site of obstruction in most chronic airway diseases. Expiratory computed tomography (CT) is increasingly used to assess obstruction at this level but there is no consensus regarding the best quantification method. We aimed to evaluate software-assisted CT quantification of air trapping for assessing small airway obstruction and dete...

Rationale: Mucus hypersecretion has been shown to be an important cause of airway obstruction in COPD and asthma, and has been associated with fatal asthma. Previous in-vitro and in-vivo studies have provided direct evidence that the myristoylated alanine-rich C kinase substrate (MARCKS) is a central regulatory molecule linking secretagogue stimulation at the goblet cell surface to mucin granul...

Postoperative airway obstructions are potentially life-threatening complications. These obstructions may be classified as functional (sagging tongue, laryngospasm, or bronchospasm), pathoanatomical (airway swelling or hematoma within the airways), or foreign body-related. Various cases of airway obstruction by foreign bodies have previously been reported, for example, by broken teeth or damaged...

OBJECTIVE To investigate the presence of airway obstruction by determining the FEV1/FVC and FEV1/slow vital capacity (SVC) ratios. METHODS This was a quantitative, retrospective cross-sectional study. The sample comprised 1,084 individuals who underwent spirometry and plethysmography in a central hospital in Lisbon, Portugal. The study sample was stratified into six groups, by pulmonary funct...

Nasal airway obstruction, a well-known cause of patient discomfort, is one of the most common presenting complaints to the otolaryngologist. The different causes of nasal airway obstruction are very wide-ranging, spanning from congenital life threatening causes to acquired benign causes. Herein, we present a case of nasal obstruction caused by widening of the posterior septum. A 52-year-old gen...

The aim of the present study was to analyse the interaction between asthma and smoking in the risk of adult airway obstruction, accounting for atopy. In the European Community Respiratory Health Survey, 15 668 persons aged 20-56 years underwent spirometry in 1991-1993 and 9 years later (n=8916). Risk of airway obstruction and lung function decline associated with smoking and early-onset (<10 ye...

EditorÐWe were interested to read O'Neil's correspondence in reference to the case report by Brimacombe and colleagues. Brimacombe and colleagues claim that the Airway Management Device (AMDÔ) cannot cause cord closure and still form an effective seal in the hypopharynx. We would like to share our experience in using the recently introduced AMDÔ that has design modi®cations claimed to prevent g...

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

Endobronchial treatments are widely used for treating airway obstruction with the goal of relieving large airway obstructions caused by malignant or benign lesions. However, they may be curative in patients with benign conditions. We aimed to evaluate the usefulness of endobronchial argon plasma coagulation (APC) and electrocautery (EC) for treating patients with airway obstruction. Methods: We...
