Intraoperative Fluoroscopy Radiation Using OEC 9900 Elite C-arm: Risk and Method for Decreasing Exposure.

The use of intraoperative fluoroscopy in surgery produces scattered radiation that can expose all operating room personnel to measurable and, in some cases, substantial radiation doses. The goal of this work is to assess and document potential radiation doses to various staff positions in a simulated standard operating room environment. Adult-sized mannequins wearing standard lead protective aprons were placed at seven positions around large and small BMI cadavers.

Solitary lymphangioma of the spine.

Study Design: This is a report of a solitary lymphangioma in a vertebral body treated by excision and autogenous bone grafting. The literature for solitary lymphangioma is reviewed.

Summary Of Background Data: An adolescent patient presented with low back pain and an abdominal mass associated with a radiographic lytic process in the L3 vertebral body.

Principles of clinical medicine: an interdisciplinary integrated 2-year longitudinal course.

In keeping with the Report of the Panel on the General Professional Education of the Physician (Association of American Medical Colleges 1984), Oregon Health Sciences University (OHSU) School of Medicine is in the midst of revising its curriculum. After a 4-year process, the Curriculum Committee mandated development of the Principles of Clinical Medicine course, a 2-year longitudinal course integrating input from both basic and clinical science departments. We describe the steps leading to the course's implementation, its administrative and organizational structure, the evaluation of student performance, teacher training, course curriculum, and the use of interdisciplinary teaching.

C5-6 cervical dislocation resulting from improper seat belt use.

Motorists may improperly use the diagonal shoulder belt of newer passive restraint systems by failing to use the lap belt. An unusual case of patient who did not wear a lap belt and who sustained a cervical C5-6 distraction injury resulting in quadriplegia is reported. Emergency physicians should be aware of this injury mechanism and should reinforce proper passive restraint use.

Use of a group objective structured clinical examination with first-year medical students.

Purpose: To evaluate the implementation of a quarterly group objective structured clinical examination (GOSCE) to assess the patient-evaluation abilities of a medical school class.

Method: The study subjects were 94 first-year students participating in the Principles of Clinical Medicine course at the Oregon Health Sciences University School of Medicine in 1992-93. To create the GOSCE, the authors modified the format of the quarterly objective structured clinical examination by making each standardized-patient station the site of an interaction between a standardized patient and a group of four or five students.
