INTRODUCTION The objective of the present study was to validate the Spanish version of the SAQLI, which is a health-related quality of life (HRQL) questionnaire specific for sleep apnea-hypopnea syndrome (SAHS), and to assess its sensitivity to change. MATERIAL AND METHODS A multicenter study performed in a group of patients with SAHS (apnea-hypopnea(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) places a huge economic burden on healthcare systems, especially patients with frequent exacerbations and co-morbidities. OBJECTIVES To identify factors associated with high utilisation of healthcare resources in a population of patients with COPD. METHOD We conducted an observational,(More)
Visceral leishmaniasis is not unusual in patients with acquired immunodeficiency syndrome (AIDS), but lung infiltration is uncommon. Leishmaniasis involving the lung often manifests as interstitial pneumonitis. We report a case in which the discovery of amastigotes in the transbronchial biopsy led to a diagnosis of leishmaniasis. However, the findings from(More)
34 tuberculosis with pleural affectation were diagnosed after examining 292 pleural effusions. 19 cases studied were diagnosed by pleuroscopy. The mean age of patients was 38 years old. The cytology, being mainly limphocytes, cultures and bacyloscopy, were all negative. The cultures of the biopsies was positive in 36.7% of the cases. The pathology report(More)
Introduction: Exacerbations of Chronic Obstructive Pulmonary Disease (COPD) that require hospital admission have a major impact on the progression of disease and generate high health costs. Method: Amulti-center, cross-sectional, observational studywas conductedwith the aim to identify factors associated with hospital admission in patients with COPD. We(More)
Objective: To evaluate the utility of inspiratory capacity (IC) measured by simple spirometry as an indirect measure of air trapping. Method: Functional residual capacity (FRC) and IC were determined, respectively, by a body plethysmography and by spirometry. Air trapping was defi ned by a FRC higher than 120%. Spearman’s rho between IC and FRC is(More)
BACKGROUND Exacerbations are a frequent cause of morbidity and mortality in COPD. It is crucial to identify risk factors for failure after treatment of exacerbations of COPD. This study evaluates the COPD severity score (COPDSS) as a predictor of clinical failure, together with other severity, activity and quality of life measurements, in patients with(More)
The usefulness of the transcutaneous oxygen tension (tcPO2) in adults is under controversy. In a varied group of respiratory patients, results of the application of this method were compared with those from the arterial blood sampling method. Thirty-eight arterial oxygen tension (PaO2) and tcPO2 simultaneous determinations were made in a group of 22(More)
QUESTION OF THE STUDY The aim of our study was to examine the relationship between health-related quality of life (HRQL), lung function parameters and intensity of dyspnea in order to determinate what variables influence the HRQL in patients with pulmonary emphysema. PATIENTS AND METHODS Forty (mean aged 66+/-9) consecutive male patients with pulmonary(More)
