[Functional capacity and cognitive performance of adults from Argentina in cardiopulmonary rehabilitation].

The study examines the efficacy of a cardiopulmonary rehabilitation program in the recovery of functional capacity and analyzes whether subjects with cardiopulmonary diseases suffer from cognitive dysfunction.

Subtle vaginal evisceration resulting in small bowel evisceration: a case report.

Background: Evisceration of bowel contents through the vagina is a rare event that may be complicated by bowel obstruction.

Objective: We report a case of vaginal evisceration with small bowel obstruction which, in contrast to previous, more dramatic case reports in the literature, is a more subtle and, in fact, characteristic clinical presentation for this unusual occurrence.

Case Report: A 72-year-old woman with a previous history of pelvic surgery presented to the Emergency Department with lower abdominal discomfort and a prolapsing mass from her vagina.

Ultrasonography-guided peripheral intravenous catheter survival in ED patients with difficult access.

Methods: This was a prospective, observational study conducted in an academic hospital from April to July of 2007. We included consecutive adult ED patients with difficult access who had ultrasonography-guided peripheral IVs placed.

Ruptured abdominal aortic aneurysm presenting as painless testicular ecchymosis: the scrotal sign of Bryant revisited.

The diagnosis of ruptured abdominal aortic aneurysm (AAA) is often missed as a result of an atypical presentation, resulting in increased mortality. Here we present an unusual case of painless scrotal ecchymosis as a presentation of ruptured AAA. We review the origin of the scrotal sign of Bryant and emphasize the importance of this uncommon finding as a diagnostic aid in atypical cases of ruptured AAA.
