Few studies evaluate the amount of particulate matter less than 2.5 mm in diameter (PM2.5) in relation to a change in lung function among adults in a population. The aim of this study was to assess the association of coal as a domestic energy source to pulmonary function in an adult population in inner-city areas of Zunyi city in China where coal use is common. In a cross-sectional study of 104...

OBJECTIVE Older people with reduced respiratory muscle strength may be misclassified as having COPD on the basis of spirometric results. We aimed to evaluate the relationship between lung function and grip strength in older hospitalized patients without known airways disease. METHODS Patients in acute medical wards were recruited who were aged ≥70 years; no history, symptoms, or signs of resp...

Objective: To investigate the effects of Qishenyiqi Dripping Pill (QDP) on pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Methods: 97 patients with chronic obstructive pulmonary disease admitted to the general wards of Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital randomized plus into experimental group (53 cases) and control group...

BACKGROUND Asthma is a non communicable chronic disease prevalent all over the world. Two commonly used methylxanthines, theophylline and doxofylline were compared in the study in stable asthmatic patients at recommended doses by various spirometric lung function tests with forced expiratory volume at second one (FEVI) between 50 to 80% of predicted FEVI. MATERIALS AND METHODS A total of 100 ...

Objective: To evaluate pre and post-operative spirometry in patients with tuberculosis sequelae undergoing lobectomy. Methods: We selected 20 patients, aged between 15 and 56 years, of both genders, with a history of tuberculosis treatment, with repeated infections or hemoptysis and indication of pulmonary lobectomy. The tuberculosis treatment time was six months, and onset of symptoms, between...

Pulmonary function was investigated in 31 consecutive patients with relatively severe Parkinson's disease. Clinical disability was assessed by Hoehn and Yahr scale, Northwestern University Disability Scale and Websterscore. All patients were on levodopa substitution therapy and used anticholinergics. Pulmonary function was investigated by spirography, determination of a maximal inspiratory and ...

QUESTION A 6-second spirometry test is easier than full exhalations. We compared the reliability of the ratio of the Forced expiratory volume in 1 second/Forced expiratory volume in 6 seconds (FEV1/FEV6) to the ratio of the FEV1/Forced vital capacity (FEV1/FVC) for the detection of airway obstruction. METHODS The PLATINO population-based survey in individuals aged 40 years and over designed t...

Currently, computer-animation programs are frequently used to instruct and stimulate young children in performing maximal expiratory flow/volume (MEFV) curves. The reproducibility and maximal performance of MEFV manoeuvres with and without the use of two computer-animation programs (the "candles" and the "balloon" programs) were evaluated. Eighty-eight children, aged 4-8 yrs, were randomly assi...

1. In five subjects, ten consecutive forced expiratory spirograms were recorded on each of 6 different days and the total forced expiratory time (FET) on each spirogram was measured. The mean overall coefficient of variation of the FET was 11.3% and of the ratio forced vital capacity (FVC)/FET was 8%. 2. Twenty-two subjects with probable small (less than 2 mm diameter) airway dysfunction as man...
