The etiology of chronic obstructive pulmonary emphysema is frequently uncertain, and the known laboratory procedures leading to a specmc diagnosis are often unrevealing. In this paper, chronic obstructive pulmonary emphysema will be discussed with reference to sweat electrolytes and the disease entity, cystic fibrosis of the pancreas. Pediatric literature frequently associates chronic obstructi...

Chronic obstructive pulmonary disease is characterized by the gradual progression of irreversible airflow obstruction and increased inflammation in the airways and lung parenchyma that is generally distinguishable from the inflammation caused by asthma. Most chronic obstructive pulmonary disease is associated with smoking, but occupational exposure to irritants and air pollution also are import...

INTRODUCTION Asthma and chronic obstructive pulmonary disease are often unrecognized and undertreated. The aim of this study was to describe the frequency of chronic obstructive pulmonary disease and asthma in primary care patients in Serbia, and to examine the agreement between general practitioners and pulmonologists on the diagnosis of chronic obstructive pulmonary disease and asthma. MATE...

Pulmonary hypertension has been the subject of many recent studies. The varieties of pulmonary hypertension can be classified as passive, obstructive, hyperkinetic, and vasoconstrictive (Wood, 1956). In the obstructive group acute and chronic pulmonary thrombosis and embolism, chronic lung disease, collagen disease, and schistosomiasis are the usual causes. A patient is described in whom an obs...

OBJECTIVE To determine the prevalence of asthma and chronic obstructive pulmonary disease in patients not known to have these disorders, who present in general practice with persistent cough, and to ascertain criteria to help general practitioners in diagnosis. DESIGN Descriptive study. SETTING Primary healthcare centre in the Netherlands. SUBJECTS 192 patients aged 18-75 years, not known...

OBJECTIVES Several studies have confirmed the high potential of the forced oscillation technique for the assessment of respiratory modifications related to chronic obstructive pulmonary disease. However, most of these studies did not employ within-breath analyses of the respiratory system. The aim of this study is to analyze respiratory impedance alterations in different phases of the respirato...

Background: In severe chronic obstructive pulmonary disease (COPD), interval training (IT) can be performed with oxygen support, which provides beneficial effect on metabolic processes, tissue perfusion, and peripheral muscle function.

OBJECTIVES To compare standard high flow oxygen treatment with titrated oxygen treatment for patients with an acute exacerbation of chronic obstructive pulmonary disease in the prehospital setting. DESIGN Cluster randomised controlled parallel group trial. SETTING Ambulance service in Hobart, Tasmania, Australia. PARTICIPANTS 405 patients with a presumed acute exacerbation of chronic obst...

background: statins have anti-inflammatory effects in patients with chronic obstructive pulmonary disease (copd). this study designed to evaluate the effects of atorvastatin on serum highly sensitive c-reactive protein (hs-crp) and pulmonary function in sulfur mustard exposed patients with copd. materials and methods: fifty patients with chronic obstructive pulmonary disease due to sulfur musta...
