To the Editor.—
As a neurologist, I object to the use of the word myelopathy in the article. The case report did not detail any spinal cord signs on neurologic examination. There were depressed deep tendon reflexes, no pathological reflexes, and no sensory abnormalities. Difficulty in swallowing was noted, yet cranial nerves were listed as normal. The examination would indicate a polyradiculopathy such as is seen in a Guillain-Barré syndrome. The spinal fluid examination demonstrated albuminocytologic dissociation with protein level above 60 mg/100 ml and no cells, a common although not a specific finding in polyradiculopathies.
