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)
BACKGROUND Gene transfer of glutamic acid decarboxylase (GAD) and other methods that modulate production of GABA in the subthalamic nucleus improve basal ganglia function in parkinsonism in animal models. We aimed to assess the effect of bilateral delivery of AAV2-GAD in the subthalamic nucleus compared with sham surgery in patients with advanced(More)
The cDNA for human beta 2-interferon (IFN-beta 2)/B-cell differentiation factor 2/hepatocyte-stimulating factor was expressed in Escherichia coli to yield a fusion protein which contains the 182 carboxyl-terminal amino acids of IFN-beta 2 fused to a 34-amino acid prokaryotic leader peptide (rIFN-beta 2). When added to cultures of human hepatoma cell line(More)
ONYX-015 is an oncolytic virus untested as a treatment for malignant glioma. The NABTT CNS Consortium conducted a dose-escalation trial of intracerebral injections of ONYX-015. Cohorts of six patients at each dose level received doses of vector from 10(7) plaque-forming units (pfu) to 10(10) pfu into a total of 10 sites within the resected glioma cavity.(More)
Gamma Knife Radiosurgery (GKRS) has been reported in the treatment of brainstem metastases while dose volume toxicity thresholds remain mostly undefined. A retrospective review of 52 brainstem metastases in 44 patients treated with GKRS was completed. A median dose of 18 Gy (range 10–22 Gy) was prescribed to the tumor margin (median 50 % isodose). 25(More)
OBJECT As a strategy to delay or avoid whole-brain radiotherapy (WBRT) after resection of a brain metastasis, the authors used high-resolution MR imaging and cavity-directed radiosurgery for the detection and treatment of further metastases. METHODS Between April 2001 and October 2009, 112 resection cavities in 106 patients with no prior WBRT were treated(More)
PURPOSE Repeat gamma knife stereotactic radiosurgery (GKRS) for recurrent or persistent trigeminal neuralgia induces an additional response but at the expense of an increased incidence of facial numbness. The present series summarized the results of a repeat treatment series at Wake Forest University Baptist Medical Center, including a multivariate analysis(More)
OBJECT In this study the authors evaluated the safety and performance of the GliaSite Radiation Therapy System (RTS) in patients with recurrent malignant brain tumors who were undergoing tumor resection. METHODS The GliaSite is an inflatable balloon catheter that is placed in the resection cavity at the time of tumor debulking. Low-dose-rate radiation is(More)
Convection-enhanced delivery of fusion proteins is a novel therapeutic approach for patients with relapsed or refractory high-grade gliomas. Multiple different fusion proteins have been produced that target different receptors on brain tumor cells. The sensitivity of different gliomas to fusion proteins has been shown to depend in part on the expression of(More)
