Patterns of verbal interaction and student satisfaction within a clinical setting: A video-enhanced observational study.

Background: The increasingly competitive global higher education sector recognises the impact of teaching quality and a strong student voice. This means that student satisfaction is under increasing scrutiny; however, little is known about how clinical teachers actually teach. At present, the relationship between actual patterns of individual dental student-clinician interaction and student satisfaction is unclear.

Bone density changes after radiation for extremity sarcomas: exploring the etiology of pathologic fractures.

Purpose: The incidental irradiation (RT) of adjacent bone that takes place during treatment of soft tissue extremity sarcomas is generally presumed to "weaken" the bone by decreasing its density, which subsequently increases the risk for pathologic fracture. This investigation intended to assess the relative effects on bone density of both RT and diminished mechanical loading secondary to tumor-induced and therapy-induced functional extremity impairment.

Methods And Materials: 19 patients treated with surgical excision and RT for soft tissue extremity sarcomas had bone density measured using dual energy X-ray absorptiometry at four sites: the irradiated (A) and contralateral (B) bone, and an uninvolved bone (C) in the treated extremity and its contralateral counterpart (D).

Anterolateral approach to the lower cervical spine: a step-by-step description.

The anterolateral approach is a popular and safe method of exposing the lower cervical spine (levels C3 to T1) for management of cervical spine disease. We present a description of the technique we use in conducting the procedure, a review of the literature, and a retrospective chart review of 30 consecutive patients who underwent cervical spine exposure via a left anterolateral approach. All patients had an uneventful perioperative course, and the two patients who experienced postprocedure symptoms recovered completely within 1 month without treatment.

Bilateral pedicle stress fractures in a female athlete: case report and review of the literature.

Study Design: Clinical case report of bilateral stress fractures of the pedicle in a female athlete presenting with back pain.

Objectives: To report this unusual case and surgical treatment and to review the relevant literature.

Summary Of Background Data: Low back pain is a frequent complaint in athletes, with the majority of cases being related to muscular or soft tissue etiology.

Bovine thrombin induces an acquired coagulopathy in sensitized patients undergoing revision spinal surgery: a report of two cases.

Study Design: A report of two cases is presented.

Objective: To raise awareness of bovine thrombin-induced factor V deficiency.

Summary Of Background Data: Bovine thrombin is a frequently used hemostatic agent in spinal surgery.
