Predictors Of Paralysis In The Rheumatoid Cervical Spine In Patients Undergoing Total Joint Arthroplasty., Jonathan N Grauer, Edwin M Tingstad, Nahshon Rand, Michael J Christie, Alan Hilibrand

Rothman Institute Faculty Papers

BACKGROUND: Rheumatoid arthritis is sometimes associated with radiographic evidence of instability of the cervical spine, most commonly an abnormal subluxation between vertebrae. When this instability compromises the space that is available for the spinal cord, it may be predictive of paralysis. However, the prevalence of radiographic signs of instability that are predictive of paralysis among patients with nonspinal orthopaedic manifestations of rheumatoid arthritis is unknown.

METHODS: Radiographs of the cervical spine of patients with rheumatoid arthritis who had undergone total joint arthroplasty over a five-year period were retrospectively reviewed. The radiographs were evaluated for predictors of paralysis (a posterior atlantodental …

Motivation For Medicine: What Factors Influence Men And Women To Enter Physician Assistant School Versus Medical School?, Ross Golla

Theses and Graduate Projects

Background The purpose of this study was to distinguish what factors were most significant in medical and physician assistant student's decision to enter medicine, in addition to comparing male and female student's motivation. Methods A survey consisting of potential motives or deterrents for entering medicine was given to medical and PA students. Results were analyzed using an independent T-test. Results PA students reported greater significance on the duration of academic and clinical training, the ability to balance work and family, the opportunity to achieve a high income, dealing with malpractice allegations and the need to be on-call as motives for …

Noninvasive Assessment Of Diffusion Hypoxia Following Administration Of Nitrous Oxide-Oxygen, Arthur H. Jeske, Clark W. Whitmire, Chris Freels, Mike Fuentes

Journal Articles

The phenomenon of diffusion hypoxia is commonly believed to occur unless nitrous oxide-oxygen inhalation sedation is followed by "washout" with 100% oxygen for 5 minutes upon termination of the flow of nitrous oxide. When systematically studied, however, this phenomenon generally appears to be unfounded. The present study evaluated the effect of breathing room air instead of 100% oxygen in healthy (ASA 1) human volunteers following administration of sedative concentrations of nitrous oxide. The occurrence of hypoxia was determined objectively, using pulse oximetry and a standardized psychomotor skills test (Trieger test). Diffusion hypoxia was not observed using these criteria.
