A respiratory therapist-driven weaning protocol incorporating daily screens, spontaneous breathing trials (SBT), and prompts to caregivers has been associated with superior outcomes in mechanically ventilated medical patients. To determine the effectiveness of this approach in neurosurgical (NSY) patients, we conducted a randomized controlled trial(More)
We enrolled 125 neurologically normal patients with intracranial aneurysms in a multi-institution, prospective, double-blind, randomized, placebo-controlled trial within 96 hours of their subarachnoid hemorrhage, to determine whether treatment with the calcium blocker nimodipine would prevent or reduce the severity of ischemic neurologic deficits from(More)
Cerebral edema is usually a complication of the later growth stages of intracranial neoplasms. Three patients with small meningiomas presented with unusually several cerebral edema out of proportion to the size of tumors. All three tumors exhibited benign meningothelial components, the formation of pseudopsammoma bodies, and striking vascular mural(More)
This study examined the effect of ethnic group membership on ethnic identity, race-related stress, and quality of life (QOL). The Multigroup Ethnic Identity Measure, the Index of Race Related Stress--Brief Version, and the World Health Organization Quality of Life--Brief Version were administered to 160 male and female participants from 3 ethnic groups(More)
Recently, a delayed hypersensitivity reaction to silicone plastics has been demonstrated in some patients with breast and joint implants and subcutaneously injected silicone. In this study, the authors examined the internal surface of shunting systems to evaluate the cellular response to implanted silicone plastic. The distal peritoneal tubing from 20(More)
Although meningiomas are known to cause varying degrees of cerebral edema, the relative importance of their location, size, histological subtype, and other histological features in the production of cerebral edema has not been studied adequately. Therefore, we undertook a retrospective analysis of 43 meningiomas excised between 1975 and 1980. The results(More)
The authors report a case of glomus tumor originating within the lumbar spine. Glomus tumors of intraosseous origin are rare, with the only case reported in the spine arising in the sacrum. The patient presented with the solitary complaint of radiating back pain that resolved postoperatively. The histopathological and radiographic findings are reviewed. To(More)
Aneurysms of the posterior inferior cerebellar artery are relatively rare. Fourteen such aneurysms (10 vertebral, 4 peripheral) are reported, and their clinical presentation, surgical therapy, and outcome are discussed. All 14 patients had suffered a subarachnoid hemorrhage; 93% (n = 13) underwent direct clipping of the aneurysm while 7% (n = 1) underwent(More)
