BACKGROUND Depression commonly complicates treatment with the cytokine interferon alfa-2b. Laboratory animals pretreated with antidepressants have less severe depression-like symptoms after the administration of a cytokine. We sought to determine whether a similar strategy would be effective in humans. METHODS In a double-blind study of 40 patients with(More)
OBJECTIVE We describe the clinical application and utility of high-resolution magnetic resonance neurography (MRN) techniques to image the normal fascicular structure of peripheral nerves and its distortion by mass lesions or trauma in the lower extremity. METHODS MRN images were obtained using a standard 1.5 Tesla magnet and custom built phased-array(More)
The pharmacologic profile of the alpha-2 agonist dexmedetomidine (Dex) suggests that it may be an ideal sedative drug for deep brain stimulator (DBS) implantation. We performed a retrospective chart review of anesthesia records of patients who underwent DBS implantation from 2001 to 2004. In 2003, a clinical protocol with Dex sedation for DBS implantation(More)
The evaluation of peripheral nerve disorders has traditionally relied on a clinical history, physical examination, and electrodiagnostic studies. Recent studies have used magnetic resonance imaging (MRI) to evaluate a variety of both nerve and muscle disorders. In this article, we describe the use of MRI, using short-tau inversion recovery (STIR) sequences,(More)
Currently, diagnosis and management of disorders involving nerves are generally undertaken without images of the nerves themselves. The authors evaluated whether direct nerve images obtained using the new technique of magnetic resonance (MR) neurography could be used to make clinically important diagnostic distinctions that cannot be readily accomplished(More)
The diagnosis of ulnar nerve entrapment at the elbow has relied primarily on clinical and electrodiagnostic findings. Recently, magnetic resonance imaging (MRI) has been used in the evaluation of peripheral nerve entrapment disorders to document signal and configuration changes in nerves. We performed a prospective study on a population of 31 elbows in 27(More)
We undertook a prospective study of 43 wrists in 32 patients who had been clinically diagnosed as having carpal tunnel syndrome (study group) and 5 wrists in people who had no symptoms (control group), correlating the clinical, electrodiagnostic, intraoperative, and magnetic resonance imaging (MRI) findings. MRI of the carpal tunnel and thenar eminence was(More)
A review of 146 medical malpractice cases involving surgery of the lumbar spine disclosed that unintended "incidental" durotomy (23 cases) was the second most frequently named occurrence. In each instance there was an associated alleged complication or sequelae. There appears to be a subset of patients in whom an unintended "incidental" durotomy is(More)
The evaluation of peripheral nerve injuries has traditionally relied primarily on information gained from the clinical history, physical examination, and electrodiagnostic testing. Taken together, all of this clinical and diagnostic information often allows one to determine the location and severity of the underlying peripheral nerve problem. However, it(More)
PURPOSE To define the safety and efficacy of carmustine polymer wafers when added to a regimen of surgery and external beam radiotherapy for treatment of a single brain metastasis. EXPERIMENTAL DESIGN Adult patients underwent craniotomy for a single brain metastasis, and carmustine polymer wafers were placed in the tumor resection cavity. Patients then(More)
