BACKGROUND Exacerbations of chronic obstructive pulmonary disease (COPD) are a leading cause of admission to hospital among men in many countries, although the factors causing exacerbations are largely unknown. The association between readmission for a COPD exacerbation and a wide range of modifiable potential risk factors, after adjusting for(More)
Chronic obstructive pulmonary disease is a smoking-related condition of progressive airflow obstruction, with disabling symptoms of chronic dyspnoea, cough and sputum production. In Spain, as in other countries worldwide, only a limited number of studies have attempted to quantify the impact of COPD on the patient, healthcare system and society. To obtain(More)
INTRODUCTION Although asthma and COPD are different pathologies, many patients share characteristics from both entities. These cases can have different evolutions and responses to treatment. Nevertheless, the evidence available is limited, and it is necessary to evaluate whether they represent a differential phenotype and provide recommendations about(More)
The main complaint of patients with chronic obstructive pulmonary disease (COPD) is shortness of breath with exercise, that is usually progressive. The principal mechanism that explains this symptom is the development of lung hyperinflation (LH) which is defined by an increase of functional residual capacity (FRC) above predicted values. Patients with COPD(More)
OBJECTIVE To study whether patients with chronic obstructive pulmonary disease (COPD) at the same level of flow limitation but with different clinical phenotypes present different degrees of systemic and/or pulmonary inflammation. PATIENTS AND METHODS We studied 15 male smokers without COPD (control group) and 39 males with COPD in stable clinical(More)
BACKGROUND Spirometric parameters can be normal in many stable asthma patients, making a diagnosis difficult at certain times in the course of disease. OBJECTIVES The present study aims to find differences and similarities in the acoustic characteristics of forced wheezes among asthma patients with and without normal spirometric values. METHODS Eleven(More)
PURPOSE During the past 10 years, the acoustic analysis of breath sounds has been used as a diagnostic tool in patients suffering from obstructive respiratory diseases. Acoustic analysis might be able to monitor the response to bronchodilator therapy in a clinical setting. So far, few studies have been carried out in asthmatic patients. To assess the(More)
The objective of the present trial was to compare the efficacy, safety, and tolerability of moxifloxacin (400 mg) given intravenously (i.v.) once daily followed by oral moxifloxacin (400 mg) for 7 to 14 days with the efficacy, safety, and tolerability of co-amoxiclav (1.2 g) administered by i.v. infusion three times a day followed by oral co-amoxiclav (625(More)
STUDY OBJECTIVES Wheezing is a common clinical finding in patients with asthma and COPD during episodes of severe airway obstruction, and can also be heard in normal subjects during forced expiratory maneuvers; however, the properties of wheezing are difficult to perceive and quantify during auscultation. We therefore developed and evaluated a new technique(More)
