Cystic tumors of the pancreas: high malignant potential.

Background: Cystic tumors of the pancreas are rare, accounting for 10% of pancreatic cysts and 1% of all pancreatic tumors; surgery is dictated by their malignant potential.

Objectives: To evaluate the malignancy rate of pancreatic cystic tumors and patient outcome, and to determine predictors for malignant potential.

Methods: We retrospectively reviewed the medical records of patients who underwent pancreatic resection for cystic tumors between January 1996 and December 2007.

[Post-operative delirium of the elderly patient--an iceberg?].

Post-operative delirium is common, and has an incidence of 37-74% as reported in different publications. The growing rates of the elderly among surgical patients makes that condition more relevant than ever, since these populations are highly susceptible to develop this condition. Contrary to the common assumption, delirium is not a unique complication of the elderly alone.

Pancreatic cancer: surgery is a feasible therapeutic option for elderly patients.

Background: Compromised physiological reserve, comorbidities, and the natural history of pancreatic cancer may deny pancreatic resection from elderly patients. We evaluated outcomes of elderly patients amenable to pancreatic surgery.

Methods: The medical records of all patients who underwent pancreatic resection at our institution (1995-2007) were retrospectively reviewed.

Pancreatic incidentalomas: high rate of potentially malignant tumors.

Background: Pancreatic incidentaloma (PI) is an increasingly common diagnosis that has received little attention. We characterized these tumors and compared them with symptomatic pancreatic tumors (nonincidentaloma [NI]).

Study Design: A retrospective database of 475 consecutive pancreatectomies that were performed from January 1995 to June 2007 at our institution was analyzed.

Usage of blood products in multiple-casualty incidents: the experience of a level I trauma center in Israel.

Objective: To predict how much blood will be needed based on the number of injured patients arriving after a multiple-casualty incident.

Design: A retrospective study evaluating data collected in 18 consecutive terrorist attacks in the city of Tel Aviv between January 1997 and February 2005.

Setting: A large, urban trauma center.

Immunomodulatory effects of ciprofloxacin in TNBS-induced colitis in mice.

Background: Crohn's exacerbation and pouchitis are commonly treated with ciprofloxacin and metronidazole. Few studies have shown an advantage of this regimen compared with other antibiotics. Most attributed the effect to its better antibacterial coverage.

Non-hip fracture-associated trauma in the elderly population.

Background: The rate of trauma in the elderly is growing.

Objectives: To evaluate the characteristics of non-hip fracture-associated trauma in elderly patients at a level I trauma center.

Methods: The study database of this retrospective cohort study was the trauma registry of a level I trauma center.
