Comparative Study
Local recurrence following breast conservation therapy in African-American women with invasive breast cancer.
African-American women have a lower survival rate than white women following a diagnosis of invasive breast cancer. Limited information is available regarding the impact of race on results of breast conservation therapy (BCT). ⋯ Overall actuarial recurrence rates were slightly higher, but not significantly different, in African-American and white women following BCT. A much less favorable pattern of local recurrence was seen in the African-American patients (P = 0.001), which may represent the presence of more biologically aggressive tumors in these women.

Surgeon-performed ultrasonography is increasingly becoming part of the initial evaluation of patients after blunt or penetrating trauma. Currently, most institutions obtain a subxyphoid or subcostal view of the heart and pericardial space, and a three-view ultrasonogram of the abdomen to detect blood in the pericardial sac or in three dependent abdominal areas. ⋯ Surgeon-performed ultrasonography has become the diagnostic test of choice for patients suspected of having hemopericardium and cardiac tamponade. Transthoracic ultrasonography is an excellent alternative for those patients where a subxyphoid or subcostal view to visualize the pericardial sac and heart cannot be obtained owing to local or anatomical factors.

Randomized Controlled Trial Clinical Trial
Ondansetron versus placebo for prophylaxis of nausea and vomiting in patients undergoing ambulatory laparoscopic cholecystectomy.
Postoperative nausea and vomiting is a common problem in patients undergoing laparoscopic cholecystectomy (LC). The purpose of this study was to evaluate the efficacy of ondansetron given at the induction of anesthesia in patients scheduled for ambulatory LC. ⋯ In patients undergoing ambulatory laparoscopic cholecystectomy, ondansetron at induction was highly effective in decreasing postoperative nausea and vomiting and should become the standard.
