The operating room (OR) is an important venue where surgeons do much of medical student teaching and yet there has been little work evaluating variables that influence learning in this unique environment. We designed this study to identify variables that affected medical student learning in the OR. ⋯ Surgical faculty behavior is a powerful determinant of student perceptions of what provides for a favorable learning environment in the OR.

Exposure is especially important for procedures performed on the liver and biliary tract where careful, precise anatomic dissection of vascular and biliary structures is required. We describe a modified subcostal incision that provides both safe exposure and versatility for most hepatobiliary procedures.

Trauma centers and the services they provide are a unique and necessary component of our health system. By design trauma centers treat all injured patients regardless of their clinical or economic needs. The purpose of this study was to quantify the costs associated with the preparation of the capacity to provide trauma care at trauma centers within the State of Florida. ⋯ Trauma centers like fire departments and police services are required to be available 24 hours a day, 7 days a week. This level of commitment by trauma centers and the reciprocal expectation from the community force trauma centers to make considerable investments in readiness. This cost of readiness is expended regardless of the patient volume or insurance status. Thus trauma centers have a large component of costs that are not captured by the traditional billing and cost accounting mechanisms within health systems and this fixed expense is extraordinarily difficult to recover given the current reimbursement environment.

The evaluation of multitrauma patients for blunt truncal injuries remains open for debate. We sought to evaluate the role of routine computed tomography (CT) of the chest, abdomen, and pelvis as a screening tool for patients already undergoing cranial CT studies. ⋯ Additional body CTs add minimal cost to the care of trauma patients but can significantly change the management. We believe it is beneficial to perform routine body CT examinations when performing cranial imaging for blunt head injury.

Previous sentinel lymph node (SLN) studies for cutaneous melanoma have shown that the SLN accurately reflects the nodal status of the corresponding nodal basin. However, there are few long-term studies that describe recurrence site patterns, predictors for recurrence, and overall survival and disease-free survival after SLN biopsy. ⋯ The incidence of nodal basin recurrence after SLN biopsy was found to be 0.6%. Primary tumor depth and pathological status of the SLN are significant predictors of local and systemic recurrence. Long-term follow-up indicates that patients with a positive SLN clearly recur sooner and have decreased overall survival than those with a negative SLN.
