Effect of glutamine use on the formation of intestinal neomucosa on peritoneal surface in rats.

Background: Short bowel syndrome (SBS) is a clinical condition with high mortality and morbidity, which leads to the lack of absorption of fluids or nutrients necessary for the body due to the decrease in the length of the small bowel (SB). Glutamine is an amino acid essential for the nutrition and proliferation of intestinal mucosa cells. The main aim of the present study was to investigate the effect of glutamine on intestinal neomucosa formation in rats which developed SBS.

Reverse Trendelenburg position applied prior to pneumoperitoneum prevents excessive increase in optic nerve sheath diameter in laparoscopic cholecystectomy: randomized controlled trial.

The aim of this randomized controlled trial was to determine whether applying the reverse Trendelenburg position before pneumoperitoneum has a preventive effect on increased intracranial pressure using optic nerve sheath diameter (ONSD) measurement as a noninvasive parameter. Seventy-nine patients were allocated to two groups according to whether pneumoperitoneum was applied in the supine position (group S, n = 40) or in the reverse Trendelenburg position (group RT, n = 39). The ONSD was measured at the following time points: T0: before anesthesia; T1: after endotracheal intubation; T2: after pneumoperitoneum in group S and after positioning in group RT; T3: after positioning in group S and after pneumoperitoneum in group RT; T4: 30 min after endotracheal intubation, and T5: after desufflation.

Comparison of the Effects of Glutamine, Curcumin, and Nesfatin-1 on the Gastric Serosal Surface Neomucosa Formation: An Experimental Rodent Model.

Introduction. Short bowel syndrome can crop up if more than 50% of small intestine is resected or when less than 100 cm of small bowel is left. Glutamine is the main food source of enterocytes.

Nesfatin-1 alleviates extrahepatic cholestatic damage of liver in rats.

Obstructive jaundice (OJ) can be defined as cessation of bile flow into the small intestine due to benign or malignant changes. Nesfatin-1, recently discovered anorexigenic peptide derived from nucleobindin-2 in hypothalamic nuclei, was shown to have anti-inflammatory and antiapoptotic effects. This study is aimed to investigate the therapeutic effects of nesfatin-1 on OJ in rats.

Isolated thyroid metastasis from renal cell carcinoma.

Metastatic neoplasms of the thyroid are uncommon when compared to primary tumors of the gland. Renal cell carcinoma (RCC) is a highly aggressive tumor of the urinary system. It can spread all over the body.

Abdominal cocoon syndrome is a rare cause of mechanical intestinal obstructions: a report of two cases.

Background: Abdominal cocoon syndrome is also known in the literature as sclerosing peritonitis or sclerosing encapsulating peritonitis. It is characterized by total or partial encapsulation of abdominal viscera by a fibrous membrane. It has been reported mainly in adolescent women and the majority of the cases are of unknown etiology.

Cecal diverticulitis mimicking acute Appendicitis: a report of 4 cases.

Diverticulum of the cecum is a rare, benign, generally asymptomatic lesion that manifests itself only following inflammatory or hemorrhagic complications. Most patients with inflammation of a solitary diverticulum of the cecum present with abdominal pain that is indistinguishable from acute appendicitis. The optimal management of this condition is still controversial, ranging from conservative antibiotic treatment to aggressive resection.
