Abstract

Three homogeneous groups of patients with silicosis, coal workers' pneumoconiosis and arc welders' pneumoconiosis had been reexamined after an interval of six years. The same examinations were repeated on each occasion with the purpose of evaluating the evolution of radiographic and functional changes. The clinical course, roentgenographic findings and results of function tests differed in the three groups. In silicosis and coal workers' pneumoconiosis the roentgenographic changes showed distinct progression. This progression was less evident in coal workers' pneumoconiosis, but deterioration of pulmonary function was more pronounced than in silicosis, apparently due to emphysema. In pneumoconiosis of welders roentgenographic changes showed a clear tendency to regression and respiratory function was not impaired.

不同类型尘肺病的功能性呼吸障碍的演变。
对矽肺、煤工尘肺和弧焊工尘肺三组患者每隔6年进行复检。每次都重复同样的检查,目的是评估放射学和功能变化的演变。三组患者的临床病程、x线表现和功能检查结果不同。矽肺和煤矿工人尘肺的x线表现出明显的进展。这种进展在煤工尘肺中不太明显,但肺功能的恶化比矽肺更明显,显然是由肺气肿引起的。焊工尘肺的x线改变显示明显的消退趋势,呼吸功能未受损。
