Early cystic thoracic cord cavity complicating decompressive surgery for spondylotic spinal canal stenosis. Case report.

This is a report of a patient who developed thoracic cystic myelopathy immediately following an otherwise successful decompression operation for spondylotic stenosis secondary to osteophyte formation of the thoracic spinal canal. As this case shows, thoracic laminectomy is not without risks, and cystic myelopathy is a potential complication that should be borne in mind when surgery for spondylosis is being planned. Cavitation of the spinal cord may be associated with trauma secondary to extramedullary cord compression.

Neuropsychological differences but comparable regional cerebral blood changes in asymptomatic HIV-1-positive and -negative drug addicts.

The objective of this study was to characterize the cognitive status of a population of asymptomatic HIV-positive drug addicts (patient group) to document the relationship between neuropsychological results and cerebral blood flow defects as measured by single photon emission computed tomography. As a control group we employed an age-matched population of HIV-seronegative drug addicts. Some neuropsychological differences were found between patients and controls and between drug addicts and normal population. We could not detect any difference in cerebral blood flow rates among HIV-1-positive and -negative drug addicts.
