Psoriasis, an inflammatory autoimmune disease, is characterized by increased level and activity of the proinflammatory cytokine TNF-alpha in affected lesions. Two promoter region polymorphisms of the TNF-alpha locus--one at position -308 and the other at -238--were examined in 99 Caucasian patients (64 with type I and 35 with type II psoriasis) and in 123(More)
BACKGROUND Intracranial intra-arterial calcifications (ICAC) are a common finding on head CT examinations, but their significance is not known. The aim of this study is to determine if a relationship exists between ICAC on head CT and the presence of a high-grade atherosclerotic stenosis on cerebral angiography. METHODS This was a retrospective study of(More)
The serial reproducibility of an individual's isokinetic torque was assessed in order to establish a reliable baseline value for future comparison. Thirty-two controls and twenty arthritic patients were tested for their peak isokinetic torque on knee flexion and extension and hip flexion at three velocities on five occasions, at fortnightly intervals. The(More)
A percutaneous technique for visualizing sacral nerve roots is described. A fiberscope was inserted into the subarachnoid space through a sheath that was inserted via a percutaneous lumbar puncture. The sacral nerve roots were identified with endoscopic visualization and x-ray fluoroscopy localization of the endoscope. These images were compared with those(More)
OBJECT The purpose of this paper was to demonstrate the usefulness of various fiberoptic endoscopes for percutaneous intraspinal navigation of the spinal canal, posterior fossa, and ventricular system. METHODS Fresh, unembalmed cadavers were used, in which lumbar punctures were made for access to the subarachnoid space (in the case of larger [3.8- and(More)
BACKGROUND Solid organ transplant patients frequently develop posttransplant malignancies including breast cancer. They may desire breast reconstruction after mastectomy, which could potentially be complicated by their transplant status, immunosuppressive regimen, and previous operations. We review our experience with patients who have undergone solid organ(More)
BACKGROUND AND PURPOSE Hypothermia has been shown to be beneficial in the setting of acute SCI. However, widespread use has been hindered by the need for systemic hypothermia as the vehicle for achieving spinal cord hypothermia. This study demonstrates that localized spinal cord hypothermia can be achieved via a percutaneous approach while maintaining(More)
This retrospective study examined the length of time patients spent in the postanesthesia care unit (PACU) recovering from a subarachnoid block with either bupivacaine hydrochloride or tetracaine hydrochloride with and without epinephrine after total knee replacement surgery or total hip replacement surgery. One hundred subjects' charts were reviewed with(More)
