[Endocrine myopathies. Muscular lesions in thyrotoxicosis]

The authors studied 42 patients with endocrine myopathy. In thyrotoxic myopathy prevalent muscle lesions of the pelvic girdle and femur were found. EMG studies (with the aid of point electrodes), histological and histochemical studies of the muscles in patients with thyrotoxicosis indicate a primary muscular character of the atrophies. The report contains descriptions of pathomorphological and histochemical changes in the muscles in experimental thyrotoxic myopathy.
