Hoarseness due to subcutaneous emphysema: a rare presentation of diverticular perforation.

Pneumomediastinum and subcutaneous emphysema usually result from alveolar rupture and rarely from colonic perforation. Although steroid use has been shown to increase the risk of complicated diverticulitis, there is limited data on the role Addison's disease may play in the development of colonic perforation. We present a rare case of a patient with Addison's disease who presented with hoarseness and was found to have massive subcutaneous emphysema, pneumomediastinum, and pneumoretroperitoneum secondary to complicated diverticulitis.

Management of High Grade Splenic Injuries in Rural America.

BACKGROUND: Rural surgeons face unique challenges when managing patients with high-grade (III-V) blunt splenic injury (BSI) given limited access to interventional radiology and blood products. Patients therefore may require transfer for splenic artery embolization (SAE) when resuscitation may still be ongoing. This study aims to evaluate current resource utilization in a rural trauma population with limited access to SAE and blood products. METHODS: Retrospective analysis of adult patients with high-grade BSI at one Level 1 trauma center and two Level 2 trauma centers was performed. Patients were evaluated for resources used after transfer to the regional trauma center. Primary outcomes measured were SAE, operative management (OM), and blood product utilization. Secondary outcomes measured included injury severity score (ISS) and mortality. RESULTS: Final analysis included 134 transferred patients. 16% underwent SAE, 16% underwent OM, and 69% were treated successfully with nonoperative and non-procedural management (NOM). 52% of the SAE patients had sustained a grade III splenic injury, 38% grade IV, and 10% grade V. 84% of patients required <3 units of packed red blood cells (PRBC) and 57% of patients required none. 80% of transferred patients required <3 total units of all combined blood products. DISCUSSION: The majority of patients with BSI transferred to a tertiary trauma center from a rural facility were successfully managed without SAE and required minimal transfusion of blood products. In the absence of other injuries necessitating transfer to a tertiary trauma center, rural surgeons should consider management of high grade splenic injuries at their home institution.

Effects of acute alcohol intoxication on verbal memory in young men as a function of time of day.

This experiment examined whether the time of day of alcohol administration influences alcohol metabolism and the impact of alcohol on verbal memory. It was hypothesized that circadian fluctuations in endogenous levels of testosterone in young men would differentially affect blood alcohol levels, which would consequently impair their memory performance to a different degree. Participants were administered alcohol or placebo drinks either at 8am or 6pm and recall of 4 prose passages was examined. The results indicated that recall declined for subjects administered alcohol but time of day did not moderate these effects. Nevertheless, generally alcohol breath levels changed in the predicted direction as a function of the time of the day with higher levels recorded in the morning and lower levels in the afternoon. The results suggested that observed differences in breath alcohol levels may be influenced by differences in endogenous levels of testosterone, but the effect of this presumed interaction on verbal memory appears inconclusive.
