title: [Recurrent peripheral nerve palsies and concomitant chronic neuropathy. Neuromusclar electrophysiologic study and neuropathologic examination: apropos of 5 cases].
abstract: The authors report 5 personal cases (3 in the same family) of patients suffering from recurrent peripheral nerve palsies usually induced by pressure and review the relevant literature. There is evidence in such cases of a mild, chronic, diffuse, subclinical neuropathy which can be recognized by electrophysiological examination. Examination of peripheral nerve biopsy material in such cases shows evidence of both axonal and Schwann cell abnormalities with evidence of neurogenic atrophy of skeletal muscles. This chronic subclinical neuropathy which is often familial can be distinguished from other chronic primary neuropathies with or without myelin sheath proliferation and hypertrophy.
