Lung function tests (forced expiratory volume in one second (FEV1), forced vital capacity
(FVC) and FEV1/FVC%) were related to silica exposure and the extent of radiological …

In an examination of the relationship between silicosis and lung function, relevant studies of
silica-exposed workers were reviewed. Smoking, dust exposure, and emphysema are three …

45 granite crushers and 45 age and smoking matched referents underwent pulmonary
function tests in 1976 and 1988. On average, the granite crushers at follow up had worked …

Background It has been established that occupational exposure to silica dust may cause
significant impairment of pulmonary function. To compare the contribution of silicosis and …

Objective: To evaluate silica exposure and respiratory disease in granite workers. Methods:
A cross-sectional study of 440 active granite workers. Results: Seventy-seven (17.5%) have …

Backgrounds: Pulmonary function decreases by advancing age in adults. Its results
decrease in volume and airflow in SPIROMETRY. This decrement accentuates with cigarette …

To investigate the relationship of lung function, airflow limitation, and lung injury in silica-
exposed workers, we analyzed the clinical, functional, and radiologic data of 94 long-term …

Background: A secondary spontaneous pneumothorax is a complication of an underlying
pulmonary disease. In recent years, there have been only a few scattered reports of patients …

In order to assess the effect of silicosis on lung function, 61 gold miners with radiological
silicosis were compared with 61 controls. Each pair was matched for age, dust exposure …

OBJECTIVES To investigate the risk factors predicting radiological progression in silicosis in
a prospective cohort study of patients with silicosis who were previously exposed to silica …
