in order to evaluate the relationship between the concentration of welding fumes and cigarette smoke on the bronchopulmonary system function, a comparative study of spirometric measurements in 100 welders and 50 healthy volunteers was performed in an automobile manufacturing company. two groups of workers were matched according to their age, height, smoking habit, years of service and social cl...

An i.v. solution of 5% dextrose with doxapram 2 mg ml-1 or 5% dextrose alone was administered to 53 patients following lateral thoracotomy. Estimations of arterial PO2, PCO2 and pH were made before operation, during infusion and 7 days after after operation. Respiratory function tests were carried out before and 7 days after operation. There were no significant differences in arterial PO2, PCO2...

BACKGROUND Patients with a mediastinal mass are at risk for cardiorespiratory complications in the perioperative period. The authors' objectives were to evaluate the incidence of life-threatening intraoperative cardiorespiratory and postoperative respiratory complications in adult patients and to study the usefulness of clinical signs and symptoms, radiologic evaluation, and pulmonary function ...

introduction: imatinib, a tyrosine kinase inhibitor which resulted in much improvement in the treatment of chronic myelogenous leukemia (cml), may adversely affect thyroid gland function. to date, assessment of thyroid function during imatinib therapy has limited to retrospective studies. the aim of this study was to evaluate the effects of imatinib on thyroid function in a prospective manner. ...

BACKGROUND Non-invasive ventilation (NIV) improves survival and quality of life in amyotrophic lateral sclerosis (ALS) patients. The timing of referral to a home ventilation service (HVS), which is in part based on respiratory function tests, has shown room for improvement. It is currently unknown which respiratory function test predicts an appropriate timing of the initiation of NIV. METHODS...

Pulmonary Function Tests (PFTs) can used to analyze and screen respiratory conditions, counting COVID-19. Ponders have appeared that PFT variations from the norm are common in patients with severe  COVID-19, these anomalies related longer hospital stays worse outcomes. This was a prospective cross-sectional study, convenient sampling evaluate function of discharged one three COVID hospital...

airway mucus hypersecretion health effects caused by air pollutants may range from subtle biochemical or physiological signs, such as mildly reduced lung function, to difficult breathing, wheezing, coughing and exacerbation of existing respiratory conditions such as asthma. the aim of this study was measuring the adverse health effects of air pollution on lung function of primary school student...

Amniotic fluid phospholipids from 346 patients' specimens were quantified and evaluated against the clinical outcome (i.e., respiratory distress syndrome or normal respiratory function). Concentrations of lecithin, sphingomyelin, phosphatidylglycerol, and the lecithin/sphingomyelin reflectance ratio were evaluated by ordered frequency distribution and stepwise discriminant function analysis. Th...
