OBJECT There is considerable debate among spine surgeons regarding whether fusion should be used to augment decompressive surgery in patients with symptomatic lumbar spinal stenosis involving Grade I degenerative spondylolisthesis. The authors prospectively evaluated the outcomes of patients treated between 2000 and 2002 at two institutions to determine(More)
BACKGROUND The comparative effectiveness of performing instrumented (rigid pedicle screws affixed to titanium alloy rods) lumbar spinal fusion in addition to decompressive laminectomy in patients with symptomatic lumbar grade I degenerative spondylolisthesis with spinal stenosis is unknown. METHODS In this randomized, controlled trial, we assigned(More)
Ninety-six children received morphine 0.1 mg/kg (n = 47) or ketorolac 1 mg/kg (n = 49) intravenously (IV) in a prospective, randomized, double-blind fashion, after tonsillectomy. Recovery variables and complications were recorded while subjects were in the hospital and parent(s) were contacted 24 h and 14 days after surgery. There were no differences in(More)
Epidural cavernous angiomas are apparently rare lesions. We present an unusual case of chronic lumbar radiculopathy secondary to an epidural cavernous hemangioma extending into the intervertebral foramen. Few such reports have had the benefit of modern neuroimaging techniques to aid in preoperative diagnosis, and, therefore, magnetic resonance imaging of(More)
The authors report a case of metastatic gastrointestinal adenocarcinoma to the cervical spine in a patient with acquired immunodeficiency syndrome (AIDS) being treated with antiretroviral therapy. The source of this tumor could not be identified despite a thorough evaluation. A 49-year-old male being treated for AIDS presents with worsening neck pain and(More)
OBJECTIVE To determine whether patients who learned the views of an expert surgeons' panel's assessment of equipoise between 2 alternative operative treatments had increased likelihood of consenting to randomization. BACKGROUND Difficulty obtaining patient consent to randomization is an important barrier to conducting surgical randomized clinical trials,(More)
The effect of immunologic hypersensitivity to a metabolite of halothane (trifluoroacetate) on the halothane-hypoxia-induction model was tested in mice and rats. Male Fisher 344 rats (200 g) were immunized with ovalbumin-trifluoroacetate (OVA-TFA) and the time course of the delayed hypersensitivity response determined. The animals had a peak response between(More)
This study was designed to investigate learning and retention of isolated sign vocabulary as a function of sign classification (iconic, opaque, or abstract). The subjects were 28 hearing college students naive to sign vocabulary. They were drilled with 30 signs from American Sign Language that had been classified as iconic, opaque, or abstract. Training was(More)
