Introduction Smoking is a major risk factor for numerous diseases; it is necessary to analyze the impact that the habit can have on vocal health. Objectives To determine the influence of smoking on changes in vocal production and lung vital capacity compared with nonsmokers. Methods This cross-sectional study compared smokers and nonsmokers (24 subjects each). Each participant underwent a vocal...

The effects of mitral valve disease on lung function have been studied in 26 non-smoking patients by relating values for lung volumes and carbon monoxide transfer factor (TLCO) to various indices of cardiac function measured at catheterisation. In general, more severe mitral disease was associated with greater abnormalities of lung function. Reductions of the one-second forced expiratory volume...

OBJECTIVE To assess the effects of obesity on lung volume and capacity in children and adolescents. DATA SOURCE This is a systematic review, carried out in Pubmed, Lilacs, Scielo and PEDro databases, using the following Keywords: Plethysmography; Whole Body OR Lung Volume Measurements OR Total Lung Capacity OR Functional Residual Capacity OR Residual Volume AND Obesity. Observational studies ...

Background: The vascular response to recurrent tissue hypoxia and reperfusion following red blood cell sickling causes acute chest syndrome and chronic lung disease. The purpose of this study was to determine the pattern of chronic lung lesions and possible risk factors in sickle cell patients in lagos, Nigeria.Methods: From July 2012 to April 2013, Pulmonary function test (PFT) and chest-x-ray...

Lung mechanics and airway responsiveness to methacholine (MCh) were studied in seven volunteers before and after a 20-min intravenous infusion of saline. Data were compared with those of a time point-matched control study. The following parameters were measured: 1-s forced expiratory volume, forced vital capacity, flows at 40% of control forced vital capacity on maximal (Vm(40)) and partial (Vp...

introduction: pulmonary involvement is the most common cause of mortality and disability in patients with systemic sclerosis and it significantly affects the quality of life in these patients. therefore, early diagnosis and treatment of pulmonary involvement seems necessary in patients with ssc. in this study, we aimed to assess the health-related quality of life (hrqol) in patients with sclero...

A decreased inspiratory capacity (IC)/total lung capacity (TLC) ratio is associated with dynamic hyperinflation and decreased exercise capacity. The present authors hypothesised that static (low IC/TLC) and dynamic hyperinflation impair cardiac function as assessed by oxygen pulse at rest and during cardiopulmonary exercise testing (CPET). Lung function, body mass index, hand grip strength and ...
