BACKGROUND The reported diagnostic yield from bronchoscopies in patients with lung cancer varies greatly. The optimal combination of sampling techniques has not been finally established. The objectives of this study were to find the predictors of diagnostic yield in bronchoscopy and to evaluate different combinations of sampling techniques. METHODS All(More)
AIM The aim of the study was to evaluate endobronchial ultrasound (EBUS) for peripheral lung lesions and to find the most cost effective combination of sampling techniques. MATERIALS 264 patients with lesions suspicious of malignancy were recruited in Bergen and Aalesund, Norway from 2005 to 2008. METHODS The study was a prospective randomised cohort(More)
BACKGROUND The choice of sampling techniques in bronchoscopy with sampling from a visible lesion will depend on the expected diagnostic yields and the costs of the sampling techniques. AIMS The aim of this study was to determine the most economical combination of sampling techniques when approaching endobronchial visible lesions. METHODS A cost(More)
Endobronchial ultrasonography (EBUS) using balloon-embedded probes may cause airway obstruction and requires a rapid scanning procedure. Three-dimensional (3-D) postprocessing of sequential 2-D images may allow detailed studies on a rapidly acquired image volume. We applied a 3-D reconstruction program on EBUS recordings acquired with a radial-scanning(More)
BACKGROUND Can plasmapheresis improve disease severity and lung function and reduce steroid doses in severe asthma patients dependent on oral corticosteroids? METHODS A pilot study with four asthma patients was undertaken using PEF (peak expiratory flow) symptom score, number of puffs of beta2-agonist, and dose of systemic steroids as disease variables.(More)
We describe a patient with a 19-year history of lymphocytic lung infiltrations. A diagnosis of lymphocytic interstitial pneumonitis was made in 1982 after an open lung biopsy, but in 1995 a comprehensive re-evaluation led to the diagnosis of Waldenström's macroglobulinaemia with primary bronchopulmonary involvement. It could also be demonstrated by(More)
