BACKGROUND To determine the prevalence of blebs or bullae using thoracoscopy in young healthy adults, and to compare patient characteristics among those with and without blebs. METHODS Bilateral thoracoscopic evaluation of the lungs was performed in healthy individuals who were referred for thoracoscopic thoracic sympathectomy for essential hyperhidrosis.(More)
BACKGROUND Risk factors for methicillin-resistant Staphylococcus aureus (MRSA) in Cystic Fibrosis (CF) and the impact on CF disease progression are still under debate. The objectives of this study were to determine clinical variables associated with MRSA colonization and examine impact on FEV(1) evolution in CF patients. METHODS A retrospective(More)
A 51-year-old active smoker with primary acquired pulmonary alveolar proteinosis (PAP) diagnosed by biopsy and anti-GM-CSF antibodies was treated safely with whole-lung lavage (WLL). This resulted in a rapid improvement of symptoms and arterial blood oxygenation, but not of standard lung function parameters. However, we also performed the multiple-breath(More)
BACKGROUND Chronic airway infection with methicillin-resistant Staphylococcus aureus (MRSA) in patients with cystic fibrosis (CF) is an increasing clinical problem, and therapeutic options are limited. Because chronic infection with MRSA can be associated with accelerated decline in lung function, eradication of MRSA is attempted in most CF centres today.(More)
We investigated the extent of convective ventilation heterogeneity contributing to the observed lung clearance index values in adult cystic fibrosis patients, as the result of two simulated scenarios, either 1) a fixed part of the lungs becoming increasingly less compliant, or 2) an increasingly greater part of the lung being less compliant. In 25 cystic(More)
Severe convective ventilation heterogeneity occurring in CF lung disease requires a modified method to determine acinar and conductive components of ventilation heterogeneity from normalized phase III slope (Sn) curves. Modified Sacin* and Scond* (as opposed to standard Sacin and Scond) are proposed and interpreted on the basis of 2 conceptual mechanisms:(More)
BACKGROUND Treating acute infectious exacerbations in cystic fibrosis (CF) patients with intravenous antibiotic therapy leads to variability in lung function and the ventilation distribution response. Part of the variable lung clearance index (LCI) response could be associated with the variable peripheral effects of intravenous antibiotic administration. (More)
A 67-year-old never-smoker was diagnosed with diffuse panbronchiolitis (DPB) and was started on 250 mg azithromycin twice weekly. Over a 16-month observation period, lung function was assessed monthly, including a dedicated small airways test, the multiple breath nitrogen washout (MBW) with indices S(cond) and S(acin) of ventilation heterogeneity at the(More)
