ReviewRecent advancements in medical simulation: patient-specific virtual reality simulation.
Patient-specific virtual reality simulation (PSVR) is a new technological advancement that allows practice of upcoming real operations and complements the established role of VR simulation as a generic training tool. This review describes current developments in PSVR and draws parallels with other high-stake industries, such as aviation, military, and sports. ⋯ PSVR is a promising technological advance within medicine. The majority of simulators are still in the prototype phase. As further developments unfold, the validity of PSVR will have to be examined much like generic VR simulation for training purposes. Nonetheless, similar to the aviation, military, and sport industries, operative performance and patient safety may be enhanced by the application of this novel technology.

Traumatic aortic injuries associated with major visceral vascular injuries in major blunt trauma patients.
The objectives of this study were to report the clinical and radiological characteristics and outcomes of a series of acute traumatic aortic injuries (ATAIs) with associated injury to major aortic abdominal visceral branches (MAAVBs). ⋯ Aortic injuries associated with MAAVB injuries in major trauma patients seem to present in a different clinical scenario. These patients present increased risk of rhabdomyolysis, visceral ischemia, and acute renal failure, as well as higher in-hospital mortality. A multidisciplinary approach combining endovascular and open surgical techniques for a staged treatment of these life-threatening aortic and MAAVB injuries is mandatory in this critical subset of trauma patients.

Rate of clinically significant postoperative pancreatic fistula in pancreatic neuroendocrine tumors.
In 2005, the International Study Group of Pancreatic Fistula (ISGPF) developed a definition and grading system for postoperative pancreatic fistula (POPF). The authors sought to determine the rate of POPF after enucleation and/or resection of pancreatic neuroendocrine tumors (PNET) and to identify clinical, surgical, or pathologic factors associated with POPF. ⋯ We found a clinically significant POPF rate after surgery in PNET to be 23.7 % with no difference by the type of operation. Our POPF rate is comparable to that reported in the literature for pancreatic resection for other types of tumors. Certain inherited genetic diseases-von Hippel-Lindau disease (VHL) and MEN-1-were associated with higher POPF rates.

Evaluation of the appendicitis inflammatory response score for patients with acute appendicitis.
Acute appendicitis is still a difficult diagnosis. Scoring systems are designed to aid in the clinical assessment of patients with acute appendicitis. The Alvarado score is the most well known and best performing in validation studies. The purpose of the present study was to externally validate a recently developed appendicitis inflammatory response (AIR) score and compare it to the Alvarado score. ⋯ This study externally validates the AIR Score for patients with acute appendicitis. The scoring system has a high discriminating power and outperforms the Alvarado score.
