Özet
Objective: Combustion of biomass fuel, is the primary source of exposure in developing countries. The description of the clinical picture of the possible pulmonary involvement in this form of indoor pollution is not well known. Our aim was to indoor air pollution determine the clinical and radiological characteristics of female patients exposed to biomass smoke, to show bronchoscopic findings and to determine the association of bronchoscopic findings with the duration of exposure. Material and Methods: The subjects of this study consisted of 20 non-smoking female patients with a history of using biomass fuel composed of animal dung who underwent bronchoscopic procedures for various diagnostic indications. The distinctive clinical features, radiological findings and nature of bronchoscopic lesions were analyzed retrospectively. The bronchoscopic findings were graded as grade I (anthracotic staining on overlying mucosa) and grade II (bronchial narrowing or obliteration due to anthracotic plaques). Results: Chief complaint was dyspnea on exertion (85%). The most frequent radiological finding on chest X-ray was reticular and/or reticulonodular infiltration (70%). The mean duration of biomass smoke exposure was 37.70 ± 19.53 years. Eleven patients were had grade I while 9 patients had grade II bronchoscopic findings. A statistically significant correlation was found between the exposure duration and bronchoscopic grade (p< 0.005). Conclusion: These findings suggest that long-standing domestic exposure to biomass smoke contributes not only to anthracotic staining on overlying mucosa, but also to bronchial narrowing or obliteration. To evaluate the role of bronchoscopic grade in different lung diseases that may be related with biomass fuel, prospective research is needed. © 2010 by Türkiye Klinikleri.
