We treat patients after appendectomy for perforated appendicitis with patient controlled analgesia (PCA) using a background continuous dose. We usually place urinary catheters in these patients because of concerns of urinary retention. The objective of the present study was to determine the rate of urinary retention in this patient population when a catheter was not used or was removed before the continuous PCA infusion was discontinued. ⋯ Patients with a perforated appendicitis who receive a continuous PCA have a low rate of urinary retention whether or not a catheter has been placed intraoperatively.

Pediatric surgery fellowship is considered one of the most competitive subspecialties in medicine. With fierce competition increasing the stakes, publications and first authorship are paramount to the success rate of matching. We analyzed Electronic Residency Application Service applications for verification of authorship to determine rate of misrepresentation. ⋯ The pediatric surgical pool has a very low incidence of suspicious citations; however, authorship claims should be verified.

Pneumothoraces are relatively common among trauma patients and can rapidly progress to tension physiology and death if not identified and treated. We sought to develop a reliable and reproducible large animal model of tension pneumothorax and to examine the cardiovascular effects during progression from simple pneumothorax to tension pneumothorax. ⋯ A reliable and highly reproducible model was created for severe tension pneumothorax in a large animal. Major cardiovascular instability proceeding to pulseless electrical activity arrest with stepwise insufflation was noted. This model could be highly useful for studying new diagnostic and treatment modalities for tension pneumothorax.
