title: Pulmonary function in sandblasters' silicosis.
abstract: Lung function was examined in 55 patients with sandblasters' silicosis. In this type of silicosis, patients with simple nodular disease had normal function. Restrictive and obstructive impairment was present in patients with large opacities, and was more marked in patients with radiographic evidence of contraction or cavitation. In the last group, striking average annual declines in ventilatory function occurred. Compared to patients with classical silicosis, these patients were younger and had intense, short exposures to free crystalline silica. The pattern of functional abnormalities suggested that restriction of lung volumes is a fundamental abnormality in this form of silicosis.
