Influence of the COPD Assessment Test respiratory item score on the decision to hospitalize patients with disease exacerbation in a hospital emergency department.

Objectives: The COPD Assessment Test (CAT) measures quality of life in patients with chronic obstructive pulmonary disease (COPD) as well as disease impact on activities of daily living. The questionnaire consists of 8 items related to breathing (cough, phlegm, chest tightness, and breathlessness) and other symptoms (low energy level, sleep disturbances, limitations on daily activities, and confidence when leaving the home). We investigated the relative impact of respiratory versus nonrespiratory scoring on the total CAT score at different moments in the course of COPD exacerbations: baseline (24 hours before an exacerbation), during the exacerbation, 15 days later, and 2 months later.

Usefulness of an angioplasty balloon as selective bronchial blockade device after transbronchial cryobiopsy.

Background And Objective: Transbronchial cryobiopsy (TBCB) is a technique in which frozen samples of lung are obtained using a probe inserted through a bronchoscope. We performed a retrospective study to assess the performance of the TBCB procedure complemented by segmental bronchial blockade using an angioplasty balloon, in terms of diagnostic yield and safety in diffuse parenchymal lung disease (DPLD).

Methods: Data from 100 patients with suspected DPLD (clinical and radiological findings), who underwent TBCB in our institution to establish a definitive diagnosis, were reviewed.
