A case of Hashimoto's encephalopathy: association with sensory ganglionopathy.

We report a case of Hashimoto's encephalopathy with prominent unsteadiness of gait. Nerve conduction studies and electromyographic findings were consistent with a sensory ganglionopathy. Symptoms and clinical findings resolved with high-dose corticosteroid therapy and paralleled the levels of anti-microsomal antibodies.

Recovery and prognosticators of paralysis in West Nile virus infection.

Previous studies have demonstrated that lesions of the anterior horn motor neurons are the primary pathology in patients with paralysis due to West Nile virus (WNV) infection. To characterize recovery and identify prognostic factors for the recovery of paralysis, we investigated 11 patients with electrophysiology testing and muscle biopsy, and one with autopsy. We found that limb weakness was markedly asymmetric and differed between upper and lower extremities, suggesting focal or segmental involvement of the spinal cord anterior horn.
