Pain sensitivity as a correlate of clinical status in individuals with chronic low back pain.

Study Design: A cross-sectional study of baseline correlates of clinical pain and functional status in consecutive patients being treated for chronic low back pain.

Objectives: To determine if an individual's global pain sensitivity, measured by experimental pain threshold to pressure at various regions of the body, is associated with baseline measures of clinical pain and physical functioning.

Summary Of Background Data: Previous studies have demonstrated that in individuals with chronic low back pain, clinical pain and functional status are significantly associated with demographic, structural, and psychosocial factors.

Transmission of Creutzfeldt-Jakob disease to a chimpanzee by electrodes contaminated during neurosurgery.

Stereotactic multicontact electrodes used to probe the cerebral cortex of a middle aged woman with progressive dementia were previously implicated in the accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger patients. The diagnoses of CJD have been confirmed for all three cases. More than two years after their last use in humans, after three cleanings and repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were implanted in the cortex of a chimpanzee.

Cerebral schistosomiasis caused by Schistosoma haematobium: case report.

The CNS is an unusual site of ectopic infection in schistosomiasis. Cerebral lesions are caused primarily by Schistosoma japonicum, and spinal cord lesions are due primarily to Schistosoma mansoni and Schistosoma haematobium. S.

A clinical and neuropathologic study of silk suture as an embolic agent for brain arteriovenous malformations.

Purpose: To evaluate the safety and efficacy of silk suture as an agent for preoperative embolization of cerebral arteriovenous malformations.

Methods: Clinical and histopathologic results were analyzed in six patients who underwent embolization of cerebral arteriovenous malformations using silk suture in combination with other agents.

Results: Three of the patients treated with silk hemorrhaged after embolization, and two of these patients died.
