Evolution of functional respiratory disorders in different types of pneumoconiosis.

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.

[Cerebral bioelectrical activity disorders in acute hydrazine poisoning].

The authors report changes in the bioelectric activity of the brain in acute, severe, suicidal poisoning with hydrazide. The observed group comprised 10 patients, 9 were admitted in coma, 7 had convulsions. Normal EEG tracing was found in a case of combined poisoning with hydrazide and diazepam. Low-voltage tracings with a tendency for bioelectric inactivity development were observed in 2 cases with lethal outcome. In the remaining cases high-grade diffuse changes were present, in three of them seizure activity was present additionally. Full evolution of bioelectric changes was observed in 5 patients. The time of return of normal activity ranged from several days to several weeks. Very slow improvement with incomplete normalization was found in mixed intoxication (hydrazide, barbiturates) treated with haemodialysis. The authors think that in cases with persistence of EEG changes despite regression of acute signs of poisoning intensive treatment with vitamins B should be continued.
