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 …

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 …

Background The adverse health effects of silica are still a major concern in some industries.
The purpose of this study was to evaluate pulmonary function in a group of sub-radiological …

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 …

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 …

Occupational exposure is an important risk factor for chronic obstructive pulmonary disease
(COPD), and silica dust is one of the most important occupational respiratory toxins …

In order to provide a better objective assessment of exertional dyspnea and functional
impairment due to exposure to silica, 153 workers exposed to silica dust (workers) and 62 …

Background The identification of markers that can facilitate the early diagnosis of silicosis
has remained challenging. We evaluated the association of inflammatory markers with the …

Objective: To determine whether individuals with simple silicosis have obstructive and
restrictive decrements. Methods: The prevalence of spirometric abnormalities by radiograph …

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 …
