Pulmonary changes on HRCT scans in nonsmoking females with COPD due to wood smoke exposure

摘要: Objective: To identify and characterize alterations seen on HRCT scans in nonsmoking females with COPD due to wood smoke exposure. Methods: We evaluated 42 diagnosed smokerelated 31 controls no history of exposure or pulmonary disease. The participants completed a questionnaire regarding demographic data, symptoms, environmental All the underwent spirometry chest. control groups were adjusted for age (23 patients each). Results: Most study group mild moderate (83.3%). most common findings bronchial wall thickening, bronchiectasis, mosaic perfusion pattern, parenchymal bands, tree-in-bud laminar atelectasis (p < 0.001 vs. all). generally not extensive. There was positive association between thickening hour-years Centrilobular emphysema uncommon, its occurrence did differ = 0.232). Conclusions: Wood causes predominantly changes, which can be detected by HRCT, even COPD.
