This study evaluates the residual biomechanical stability of the spine following multilevel anterior diskectomies and anterior longitudinal ligament release using video-assisted thoracoscopic surgery (VATS). Eighteen domestic pigs were randomly divided into three groups of six pigs. Group 1 underwent thoracic anterior release from T4-T9 using a left-sided VATS approach, group 2 underwent thoracic anterior release from T4-T9 via a traditional left thoracotomy (open), and group 3 did not undergo surgery and served as a control.

We previously measured polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in U.S. foods and estimated the daily dioxin toxic equivalent (TEQ) intake to be from 0.

Scatter reduction by air gaps in mammography was investigated. We have experimentally demonstrated that, independently of the imaging geometry, scatter in air-gap mammography can be well described by a virtual source of scatter (VSS) model. This model postulates that scatter radiation originates from a virtual point source of scatter placed on the central axis between the x-ray source and the exit surface of a patient at distance delta and utilizes only two parameters: delta and (S/P)0.

The purpose of this study was to assess the role of the anterior cervical plate in the treatment of cervical spondylosis. Forty-three patients surgically treated for cervical spondylosis were reviewed. The technique for discectomy and fusion was the same for both groups (Smith-Robinson with autologous iliac crest bone graft).

Epidural abscess of the spinal column is a rare but potentially devastating disease. When recognized early and treated appropriately, the outcome can be excellent. Abscesses in the spinal subdural space or in the spinal cord proper are even more unusual but can also lead to complete and irreversible loss of neurologic function if not diagnosed and treated rapidly.

A clinically useful classification system is suggested that can be used in prospective trials to evaluate the effects of radiation on the visual system. We review radiation-induced pathophysiological and clinical changes of the various ocular structures as well as dose-response data and management of ocular complications. The rationale for the classification scheme chosen is also discussed.

Chlorinated and brominated dioxins and dibenzofurans in human tissue following exposure.

With substantial improvements in analytic techniques over the past decade, it has become possible to measure polychlorinated dioxins (PCDDs) and dibenzofurans (PCDFs) in human tissue in a congener-specific fashion down to the low parts per trillion level. This paper reviews findings using these new techniques from a number of recent medical and environmental case studies. These studies include those of workers exposed to a polychlorinated biphenyl (PCB) transformer fire in the United States, German chemical workers exposed to 2,3,7,8-tetrachlorodibenzodioxin (2,3,7,8-TCDD) while cleaning up after an explosion, workers at a municipal incinerator in New York City, a chemist exposed to brominated and chlorinated dioxins, U.

Optimal management of symptomatic cavernous angiomas (CA) located in the thalamus and the brainstem is problematic. Clinical and radiological (MRI) follow-up series suggest that having hemorrhaged once, recurrent hemorrhage with progressive neurologic dysfunction may commonly occur. We have therefore chosen to treat these lesions when first symptomatic with stereotactic linear radiosurgery (SLR).

This is the first report on occupational health hazards to dioxin chemists associated with laboratory exposure to 2,3,7,8-tetrabromodibenzodioxin (TBrDD), and further characterizes the human response to 2,3,7,8 tetrachlorodibenzodioxin (TCDD). In this case study the chemist was exposed on two separate occasions. In March 1956, after synthesizing 10 g of TBrDD, the chemist suffered from mild and transient chloracne of the neck and wrists; in September 1956, after synthesizing 16 g of TCDD, he suffered severe chloracne of the entire body, headaches, backache, and leg pain on exertion.

A biomechanical study was performed to evaluate the effectiveness of the Fixateur Interne pedicle screw system and the Syracuse I-Plate anterior fixation system. A total of 12 fresh frozen cadaver spines were tested intact, after burst fracture was created and application of a fixation device (six each), and after six serial transections of posterior ligaments and bony structures. Spines were loaded to a maximum of 10 N-m in flexion, extension, left and right lateral bending, and clockwise and counter-clockwise rotation.

Sixteen patients were treated with a new anterior internal fixation device after thoracolumbar or lumbar decompression, and fusion with bone grafting. Ten patients had acute burst fractures, four had metastatic tumors, and two had old, healed fractures with deformity. In the acute fracture group, eight patients had neurologic deficits and seven patients experienced improvement.

An experimental investigation was carried out to create burst fractures and to evaluate the mechanisms and degree of reduction of the intracanal fragment with posterior instrumentation techniques in multisegmental human cadaver specimens. Reduction of the spinal fragment through kyphosis correction and distraction was evaluated using CT imaging. With kyphosis correction alone there was no decrease in canal compromise; in some cases there was a slight increase in canal compromise.

Proliferative responses of peripheral blood mononuclear cells of rheumatoid or osteoarthritis patients and normal controls stimulated with cartilage components were studied. Two components not studied in previous cellular studies, matrix proteins (fraction A4) and lipoproteins, were used as well as whole extract of cartilage, native and denatured collagen, and proteoglycans. In general, osteoarthritis cells responded less well than the other two groups; this was statistically significant for fraction A4-matrix protein (normal p less than .
