Grill Brush Bristle Case Series: Three Unique Presentations of Ingested Foreign Bodies.

BACKGROUND Much of the medical literature regarding injury from the ingestion of wire bristles from grill brushes has been published only in the last decade. Grill brushes are often used to clean grills, and small wire bristles may break off of the brush during the scrubbing process and subsequently become embedded into food and are accidently ingested. Fewer reports have been published on abdominal presentations with injuries past the gastroesophageal sphincter, yet perforation and subsequent need for operative management has been shown to be more prevalent in these types of cases.

Do hybrid simulator-generated metrics correlate with content-valid outcome measures?

Background: Hybrid simulators provide objective metrics for laparoscopic task performance. This study aimed to evaluate the correlation between hybrid simulator-generated metrics and content-valid outcome measures.

Methods: Residents underwent training with a previously validated 5-task simulation model (5-TSM).

The effect of beta-blocker dosing strategy on regulation of perioperative heart rate and clinical outcomes in patients undergoing vascular surgery: a randomized comparison.

The optimal dosing strategy for perioperative beta-blockers to safely achieve recommended target heart rates (HRs) by current guidelines is not well defined. An HR-titrated perioperative beta-blocker dosing regimen versus a fixed-dose regimen was assessed by clinical outcomes, postoperative heart rate, and beta-blocker-related complications. Patients (n = 64) scheduled to undergo moderate- to high-risk vascular surgery and without contraindications to beta-blockade were randomized to either a fixed-dose or HR-titrated beta-blocker dosing schedule.
