Serial pulmonary function test abnormality in tuberculous pleural effusion

Background: Pleural effusion is a common clinical problem that frequently causes dyspnoea and poor ventilatory function. In addition to fluid, pleural thickening, septations and calcifications can add to the functional deterioration of lungs. The drainage of pleural effusion is very effective in improving the functionality of lungs. Large volume pleural fluid tapping results in immediate hemodynamic improvement and relief from dyspnoea.Methods: The aim of the present study was to estimate the impact of tubercular pleural effusion on the ventilatory function of the lungs and to find out the correlation between the effect of pleural tapping and functional effect on the lungs. The study comprised of thirty tubercular pleural effusion cases. They were observed for six months by doing serial chest X-rays and pulmonary function test.Results: It was observed that tuberculous pleural effusion causes a restrictive abnormality and small airway obstruction. These abnormalities improve gradually over a period of six months when the patient is on anti-tubercular treatment. The role of any therapeutic intervention towards decreasing these lung function abnormalities will be subject of separate large-scale prospective study.Conclusions: Functional defects and residual pleural thickening has no correlation with the initial severity of pleural effusion

Cystic Fibrosis: Cluster Analysis of Microbiology and Pulmonary Function

In an attempt to find a relationship between pulmonary infection and pulmonary function in cystic fibrosis (CF) patients, microbiology data and pulmonary function test (PFT) data for clinic patients\u27 visits were obtained from the University of Minnesota Relational Database. The two files were merged, totaling 12,193 cases, and then analyzed using a quick cluster subroutine of SPSSX on the University of Illinois IBM Mainframe System. QUICK CLUSTER analysis showed a relationship between the virulence of the microorganisms, the amount of growth of the microorganisms, and the pulmonary function test scores of CF patient

Pulmonary function test in patients of type 2 diabetes mellitus

Background: We are today witnessing a pandemic of diabetes mellitus (DM), globally and nationally. DM and its complications have become the most important contemporary and challenging health problems. Diabetes is not associated with any specific pulmonary symptom and hence periodic screening for lung disease is not done in diabetic patients. However, an extensive microvascular circulation and an abundant connective tissue in the lung raise the possibility that the lung may also be a target organ in diabetic patients. The aim and objectives were to study the pulmonary function of individual with type 2 diabetes mellitus patients by performing spirometry.Methods: Study included non-smoker diabetic patients, who had no history of respiratory disease, were selected for this study and undergone pulmonary function test by spirometry. The study was conducted at department of General Medicine Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, Uttar Pradesh, India.Results: Present study, author found that there was significant derangement in the spirometric readings in the diabetic patients. The FEV1/FVC values further declines as the duration of diabetes increased.Conclusions: Spirometric values (FVC, FEV1, FEV1/FVC) were consistently lower in subjects with type 2 diabetes mellitus. The effect on FVC predicted % was found to be more pronounced in subjects whose duration of DM was more than 5 years

Exercise-induced cardiac costraint by the lungs

A patient of fourty-five years old male, with severe emphysema, underwent bullectomy. He was studied, before and one year after surgery, by standard pulmonary function test and cardiopulmonary exercise test. We found that before bullectomy, tidal volume increases up to 45 W and flattens thereafter. After bullectomy tidal volume increases trough the entire exercise

Effect of chronic exposure to biomass fuel smoke on pulmonary function test parameters

Background: Life in a typical Indian household revolves around the cooking area, and Indian women spend much of their time there. Cooking stoves in most households are nothing more than a pit, a chulha (a U-shaped construction made from mud), or three pieces of brick. Cooking under these conditions entails high levels of exposure to cooking smoke. Aim of this study was to evaluate the effect of Chronic Exposure to Biomass Fuel Smoke on Pulmonary Function Test Parameters.Methods: 60 non-smoking women without any history of any major chronic illness in the past were selected for this study. The study group comprised of 30 rural female subjects who were chronically exposed to biomass fuel smoke combustion and 30 age matched urban female subjects exposed chronically to clean fuel combustion (Liquified Petroleum Gas–LPG) in Haryana (India). All the subjects were evaluated for pulmonary function tests by RMS Medspiror.Results: Biomass exposure index came out to be 85.68±3.69 for women cooking on biomass and LPG index was 64.17±6.97 for women cooking on LPG. This implies significant chronic exposure of women to biomass fuel smoke. The lung function parameters were significantly lesser in biomass exposed rural women [FEV1 (p<0.01), FVC (p<0.01), FEF25-75 (p<0.01), FEV1/FVC ratio (p<0.01), PEFR (p<0.01), MVV (p<0.01)] than the LPG exposed urban women. The evaluation of PFT suggested obstructive type of pulmonary disease.Conclusion: The derangement in pulmonary function parameters in women exposed to biomass smoke pollutants could be due to chronic significant exposure as suggested by high Biomass exposure Index. Inadequate ventilation in cooking area without chimney/vent also contributed to pulmonary function derangement and COPD.
