Article Functional and Radiological Impairment in Women Highly Exposed To Indoor Biomass Fuels(2001) Özbay, B.; Uzun, K.; Arslan, H.; Zehir, I.Objective: The aim of this study was to describe the lung function and the computed tomographic features in a selected group of non-smoking women with chronic obstructive pulmonary disease and biomass fuel exposure. Methodology: Thirty female patients currently exposed to biomass smoke were prospectively investigated for further evaluation using high resolution computed tomography (HRCT), pulmonary function tests and blood gas analysis. Results: The mean age was 59±11 years. The patients were exposed to biomass smoke for 37.4± 10 years. Pulmonary function tests revealed severe obstruction. The most common HRCT findings were increased lung volume or diffuse emphysema, thickening of interlobular septae, focal emphysematous areas, increased cardiothoracic ratio, and increased bronchovascular arborization. Conclusion: Biomass fuel has deleterious effects on pulmonary function and structure leading to obstructive and restrictive pathologies.Article Prevalence of Chronic Bronchitis-Asthma Symptoms in Biomass Fuel Exposed Females(Japanese Society for Hygiene, 2003) Uzun, K.; Özbay, B.; Ceylan, E.; Gencer, M.; Zehir, I.Objectives: We investigated whether exposure to biomass fuel is a potential risk factor for chronic bronchitis and asthma among females in rural area in Van (east Turkey). Methods: The effect of indoor pollution producing various respiratory symptoms was studied in 177 females. Of these, 90 were those who used biomass fuel and 87 were nonusers of biomass fuel. A part of the European Community Respiratory Health Survey quastionnaire and British Medical Research Council questionnaire were used. Results: Asthma related symptoms (AS) (wheezing, and combination of wheezing without a cold and wheezing with breathlessness) were reported in 63.3% of those who used biomass fuel, and in 12.9% of nonusers (p<0.0001). The use of asthma medication was reported as 3.3% of biomass fuel users, and in 2.7% of nonuser (p>0.05). Long term cough and/or morning cough together with sputum (chronic bronchitis symptoms (BS) was reported as 58.9% in the user group, and 29.4% in the nonuser group (p<0.0001). Significant differences in AS and BS were found between biomass fuel user and nonuser groups in the rural area. Conclusions: The results of this study showed a significant association between symptoms of chronic bronchitis-asthma and biomass fuel usage in females living in a rural area.
