Roger T. Sherman Lecture. Advances in the management of blunt thoracic aortic injury: Parmley to the present.
This article traces the evolution in management of blunt aortic injury (BAI) over the past 50 years from the time of the seminal description from Parmley in 1958. There have been major advances in both diagnostics and treatment paradigms with very rapid technologic advances occurring over the past decade. For many years, conventional aortography was the principle diagnostic tool, but it has been replaced by the progression of CT. ⋯ Many patients with major associated injuries have definitive treatment of BAI managed in a delayed fashion with the use of hypertensives, which appears to improve outcomes. In the past 5 years, definitive treatment has changed with the majority of injuries being treated today with endoluminal stent grafts as opposed to open thoracotomy and traditional repair techniques. Paraplegia rates have diminished from 8 to 10 per cent down to 1 to 2 per cent in association with these therapeutic advances.

Comparative StudyAcute adrenal insufficiency may affect outcome in the trauma patient.
Acute adrenal insufficiency in the trauma patient is underrecognized and the impact poorly understood. Our hypothesis was that the identification and treatment of acute adrenal insufficiency reduces mortality in trauma patients. Institutional Review Board approval for the retrospective review of a prospective database from a Level 1 trauma center for 2002 to 2004 was obtained. ⋯ The 55 (40%) responders showed no statistical differences in outcome variables whether or not they received hydrocortisone. The untreated adrenal-insufficient patients had significantly higher mortality, longer hospital length of stay, intensive care unit days, and ventilator-free days. Conclusions were: (1) treatment of acute adrenal insufficiency reduces mortality by almost 50 per cent in the trauma patient; and (2) acute adrenal insufficiency recognized by low random cortisol levels or nonresponse to a stimulation tests should be considered for treatment.

Comparative StudyPerineal injuries at a large urban trauma center: injury patterns and outcomes.
The purpose of this study was to describe the characteristics of this unique patient population, their clinical presentations, and outcomes. The Los Angeles County and University of Southern California Medical Center Trauma Registry was used to retrospectively identify patients who sustained perineal injuries. Information included gender, age, vital signs, trauma scores, mechanisms of injury, studies performed, surgeries performed, and outcomes. ⋯ Most patients with perineal injuries (93%) can be managed without colostomy. Associated injuries are not uncommon, particularly bony fractures. Mortality is mostly the result of exsanguination related to associated injuries.

Case ReportsTreatment of hyperinsulinemic hypoglycemia due to diffuse nesidioblastosis in adults: a case report.
An 82-year-old man was admitted to our hospital with a complaint of hypoglycemic syncope in the early morning. Insulinoma was suspected, but an abdominal CT showed no mass. Abdominal angiography showed a slight stain fed from the splenic artery. ⋯ Because ASVS showed that the pancreatic body and tail had a lesion producing insulin abnormally, we performed a distal pancreatectomy to cure the hypoglycemia. Clinically, it is very difficult to distinguish diffuse nesidioblastosis from insulinoma. When we treat hyperinsulinemic hypoglycemia, ASVS can be an essential examination to decide the extent of pancreatectomy.

Comparative StudyPatients with Cushing's syndrome are care-intensive even in the era of laparoscopic adrenalectomy.
We report outcomes from laparoscopic adrenalectomy (LA) comparing patients with Cushing's syndrome with those with other adrenal pathology with respect to length of stay (LOS), overall complications, and financial implications. We conducted a retrospective review of 80 continuous patients (103 glands) undergoing LA. The clinical diagnoses were: hypercortisolism (Cushing' syndrome; n=33), hyperaldosteronism (Conn's syndrome; n=20), phaeochromocytoma (n=16), and neoplasm (others; n=11). ⋯ LA in patients with Cushing's syndrome is associated with longer hospitalizations, more frequent major complications, and higher advanced care requirements, especially for patients undergoing bilateral adrenalectomy. Minor complications were infrequent and median LOS was brief regardless of diagnosis. Patients with Cushing's syndrome had higher costs for overall hospital charges, advanced care, and anesthesia.
