African American breast cancer patients have a higher mortality rate than their Caucasian counterparts. The purpose of this study was to evaluate whether race is a poor prognostic factor in breast cancer survival after multiple other prognostic factors are taken into account. ⋯ Poor survival of African American breast cancer patients seems to be related to their advanced stage at presentation and young age. To improve survival in these women, efforts should be concentrated on aggressive screening at a young age to detect the disease at an earlier stage.

Comparative Study
Measuring and developing suturing technique with a virtual reality surgical simulator.
We have developed an interactive virtual reality (VR) surgical simulator for the training and assessment of suturing technique. The surgical simulator is comprised of surgical tools with force feedback, a 3-dimensional graphics visual display of the simulated surgical field, physics-based computer simulations of the tissues and tools, and software to measure and evaluate the trainee's performance. ⋯ Data indicate differences between surgeon and nonsurgeon performance and in improvement in performance with training. One possible explanation for the superior performance of the surgeons is that their suturing skills applied well to the simulated suturing task. Additional research is required to confirm or deny the similarity between actual and simulated surgical tasks and the relevance of virtual reality surgical simulation to surgical skill assessment and training.

Breast conservation (partial mastectomy, axillary node dissection or sampling, and radiotherapy) is the current standard of care for eligible patients with Stages I and II breast cancer. Because axillary node dissection (AND) has a low yield, some have argued for its omission. The present study was undertaken to determine factors that correlated with omission of AND, and the impact of the decision to omit AND on 10-year relative survival. ⋯ A significant number of women with Stage I breast cancer do not undergo AND as part of BCS. The trend is most pronounced for the elderly, but significant fractions of women of all ages are also being undertreated by current standards. Ten-year survival is significantly worse when AND is omitted. This adverse survival effect is not solely from understaging.

Hypothermia occurs commonly in severely injured patients and is associated with a high mortality rate. It perturbs the normal homeostatic response to injury and affects multiple organ systems and physiologic processes. In trauma patients, hypothermia-induced coagulopathy often leads to marked bleeding diathesis and frequently provides a challenge for the surgeon. ⋯ Efforts to prevent and treat hypothermia in trauma patients should be instituted in the field and continued as an integral part of the resuscitation process. Hospital personnel and physicians at various levels caring for trauma patients from the initial injury and thereafter should bear in mind that a patient's temperature is as important as any other vital sign. Appropriate measures for preventing and treating hypothermia should be instituted promptly and tended to with utmost vigilance.

Laparoscopic staging is an effective and accurate means of staging pancreatic cancer. But, the frequency of subsequent surgical bypass to treat biliary or gastric obstruction in laparoscopically staged patients with unresectable adenocarcinoma is unknown. The development of biliary and gastric obstruction in patients with unresectable pancreatic adenocarcinoma has been reported to occur in as many as 70% and 25% of patients, respectively. Previously, staging for patients with pancreatic cancer was achieved by laparotomy and the anticipated high rate for these patients to develop obstruction led to prophylactic bypass procedures. As laparoscopic staging for pancreatic cancer becomes a standard modality, the need for prophylactic bypass procedures in these patients needs to be examined. ⋯ These results do not support the practice of routine prophylactic bypass procedures. As such, we propose that surgical biliary bypass can be advocated only for those patients with obstructive jaundice who fail endoscopic stent placement, and gastroenterostomy should be reserved for patients with confirmed gastric outlet obstruction.
