Impact of "Killer Immunoglobulin-Like Receptor /Ligand" Genotypes on Outcome following Surgery among Patients with Colorectal Cancer: Activating KIRs Are Associated with Long-Term Disease Free Survival.

Approximately 30% of patients with stage II/III colorectal cancer develop recurrence following surgery. How individual regulation of host mediated anti-tumor cytotoxicity is modified by the killer-cell immunoglobulin-like receptor (KIRs) genotype is essential for prediction of outcome. We analyzed the frequency of KIR and KIR ligand Human Leukocyte Antigen Class I genotypes, and their effects on recurrence and disease-free survival (DFS).

Effects of dexamethasone on ischemia reperfusion injury following pringle maneuver.

Background/aims: Hepatic ischemia reperfusion injury induced by Pringle maneuver leads to bacterial translocation, endotoxemia and apoptosis. Our aim was to compare the effects of low and high dose dexamethasone pretreatment on antioxidant enzyme activities, bacterial translocation, endotoxemia and apoptosis, following Pringle maneuver.

Methodology: Thirty-two rats were randomized into four groups; sham, control and two treatment groups; low dose dexamethasone (0.

Clinical applications of gadobenate dimeglumine-enhanced magnetic resonance cholangiography: an expanded pictorial review.

Gadobenate dimeglumine (Gd-BOPTA) is taken up by functioning hepatocellular cells and is partially excreted into the biliary system; therefore, it can be used as a potential intrabiliary contrast agent for magnetic resonance cholangiography applications for various clinical conditions such as obstructive disorders (e.g., choledocholithiasis, hepatolithiasis), inflammatory disorders (e.

Initial experience on utility of gadobenate dimeglumine (Gd-BOPTA) enhanced T1-weighted MR cholangiography in diagnosis of acute cholecystitis.

Purpose: To investigate the feasibility of the use of gadobenate dimeglumine (also known as Gd-BOPTA) -enhanced T1-weighted MR cholangiography in diagnosis of acute cholecystitis.

Materials And Methods: This prospectively designed institutional review board-approved HIPAA-compliant study was done between January and November 2007. We included 11 consecutive patients (7 male, mean age 59 years) who presented to the emergency room with acute right upper quadrant pain and with equivocal physical examination and/or ultrasound findings.

Determinants of postoperative infection after laparoscopic cholecystectomy.

Background/aims: The aim of this study was to evaluate the effect of antibiotic prophylaxis on the development of infectious complications in laparoscopic cholecystectomy.

Methodology: A total of 208 patients undergoing elective laparoscopic cholecystectomy were randomized, double-blinded into one of two treatment arms: 1) cefazolin 1 g intravenously after induction of anesthesia and 2) no prophylactic antibiotics. The patients were followed-up for infectious complications for 30 days at the out-patient clinic.

Cystic hydatid disease: current trends in diagnosis and management.

Cystic echinococcosis is endemic in certain parts of the world. The growth of the cyst is often slow, and the liver and lungs are the most frequently involved organs. Diagnosis is based on clinical signs and symptoms and epidemiological data, while ultrasonography is important for the classification of hydatid cysts.
