“…They reported that exposure to indoor open fires in poorly ventilated homes was a risk factor for COPD (15). Dennis et al (16) showed that tobacco use, wood smoke for cooking, passive smoking, and gasoline use for cooking were associated with obstructive airway disease. In that study, wood-smoke exposure was associated with the development of obstructive airways disease among females in Bogota.…”

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.

Comparative study of respiratory symptoms and lung function alterations in patients with chronic obstructive pulmonary disease related to the exposure to wood and tobacco smoke* Estudo comparativo de sintomas respiratórios e função pulmonar em pacientes com doença pulmonar obstrutiva crônica relacionada à exposição à fumaça de lenha e de tabaco AbstractObjective: To describe and analyze clinical symptoms and spirometric alterations of patients with chronic obstructive pulmonary disease (COPD) and history of exposure to wood and tobacco smoke. Methods: We retrospectively evaluated data related to 170 patients distributed into 3 groups: 34 exposed only to wood smoke, 59 patients exposed only to tobacco smoke and 77 patients exposed to both. Results: The groups did not differ significantly in terms of age (p = 0.225) or degree of exposure, considering each type of exposure in isolation or in combination (p = 0.164 and p = 0.220, respectively). Females predominated in the group exposed to wood smoke. There were no differences among the groups regarding respiratory symptoms (p > 0.05), and moderate dyspnea predominated in the three groups (p = 0.141). The group exposed to wood smoke presented higher percentages of forced expiratory volume in one second/forced vital capacity ratio and of forced expiratory volume in one second (p < 0.05). Positive results on bronchodilator testing occurred more frequently in the group exposed to tobacco smoke. The percentage of severe and extremely severe obstruction was significantly higher in the group exposed to tobacco smoke (44.1%) than in that exposed to wood smoke (11.8%; p = 0.006). Conclusions: Respiratory symptoms and pulmonary function alterations consistent with COPD were observed in the groups of patients exposed to wood smoke. However, those alterations were not as significant as the alterations observed in the groups exposed to tobacco smoke. This study emphasizes the importance of prospective studies in evaluating the risk of wood-smoke-related COPD in Brazil, as well as the need for preventive measures in this area.Keywords: Pulmonary disease, chronic obstructive; Smoking; Air pollution, indoor; Smoke. ResumoObjetivo: Descrever e analisar sintomas respiratórios e alterações espirométricas em pacientes portadores de doença pulmonar obstrutiva crônica (DPOC), com história de exposição à fumaça de lenha e de tabaco. Métodos: Foram avaliados retrospectivamente dados de 170 pacientes distribuídos em 3 grupos: 34 pacientes expostos somente à fumaça de lenha, 59 pacientes, somente à de tabaco e 77 pacientes expostos a ambas. Resultados: Os grupos não diferiram quanto a idade (p = 0,225) e grau de exposição, considerando cada tipo de exposição isoladamente ou em associação (p = 0,164 e p = 0,220, respectivamente). No grupo exposto à fumaça de lenha predominou o sexo feminino. Não houve diferença entre os grupos quanto à freqüência dos sintomas respiratórios (p > 0,05), e houve predominância de grau moderado de dispnéia nos três grupos (p = 0,141).

“…One cigarette has more than 4,000 substances producing pulmonary lesions. However, for some years, the wood burning smoke has been recognized as a COPD pathogenic agent (16)(17)(18)(19) . In this population of COPD, 25.7% of the individuals reported having been exposed to wood burning smoke, and in three of them, cigarette could not be the main COPD causal factor.…”

Chronic obstructive pulmonary disease (COPD) is a public health problem. Tobacco smoking is the major cause, but not the only one. Air pollution, exposure to chemicals, environmental smoke exposure, and passive smoking are among other contributing causes; being viral and bacterial infections also risk factors. Gender and weight are associated to the severity of the disease. Co-morbidity is frequent. Objective: Objective: Objective: Objective: To characterize a population of COPD outpatients followed at an outsourced medical service. Methods:Methods: Methods: Methods: Questionnaires were applied to patients with COPD. The data included gender, age, weight, body mass index (BMI), oxygen delivery users, and FEV 1 , exposure to tobacco smoke, exposure to wood smoke, history of tuberculosis and co-morbid diseases. Results:Results: Results: Results: Of the 70 patients enrolled in the study, 70% (49) were men with an average age of 64 ± 10 years, average weight of 63 ± 16 kg and average BMI of 22 ± 5 kg/m 2 . Mean FEV 1 was 35 ± 14% and 45.7% were oxygen dependent. Nine (12.8%) patients never smoked, while 78.8% had quit tobacco smoking, (38 ± 11 pack/years was the average). Nine (12.8%) smoked corn husk cigarettes. Eighteen (25.7%) were exposed to wood smoke. Eleven (15.7%) patients had tuberculosis, 5.7% complained of asthma symptoms, 2.8% had bronchiectasis, 11.4% diabetes mellitus, 51.4% hypertension, and 20% Cor pulmonale.
