Review Meta AnalysisEndoscopic ultrasound: it's accuracy in evaluating mediastinal lymphadenopathy? A meta-analysis and systematic review.
To evaluate the accuracy of endoscopic ultrasound (EUS), EUS-fine needle aspiration (FNA) in evaluating mediastinal lymphadenopathy. ⋯ EUS is highly sensitive and specific for the evaluation of mediastinal lymphadenopathy and FNA substantially improves this. EUS with FNA should be the diagnostic test of choice for evaluating mediastinal lymphadenopathy.

Case ReportsHemosuccus pancreaticus: problems and pitfalls in diagnosis and treatment.
Hemosuccus pancreaticus is a rare cause of intermittent upper gastrointestinal bleeding. We report two cases of hemosuccus pancreaticus with multiple episodes of upper gastrointestinal bleeding. The causes of hemorrhage were rupture of pseudoaneurysm of the splenic artery and bleeding from the wall of pancreatic pseudocyst. ⋯ Our patients herein underwent surgery without recurrence or sequelae. Intraoperative ultrasonography and pancreatoscopy were helpful modalities for confirming the source of hemorrhage and determining the cutting line of the pancreas. When we encounter intermittent upper gastrointestinal bleeding with an obscure source, hemosuccus pancreaticus should be included in differential diagnoses especially in patients with chronic pancreatitis, which would lead to a prompt and proper treatment.

Randomized Controlled TrialImpact of postoperative omega-3 fatty acid-supplemented parenteral nutrition on clinical outcomes and immunomodulations in colorectal cancer patients.
To investigate the effect of omega-3 fatty acid parenteral supplementation postoperatively on clinical outcomes and immunomodulation in colorectal cancer patients. ⋯ Postoperative supplementation of omega-3 fatty acids may have a favorable effect on the outcomes in colorectal cancer patients undergoing radical resection by lowering the magnitude of inflammatory responses and modulating the immune response.

Gastric motor effects of ghrelin and growth hormone releasing peptide 6 in diabetic mice with gastroparesis.
To investigate the potential therapeutic significance of ghrelin and growth hormone releasing peptide 6 (GHRP-6) in diabetic mice with gastric motility disorders. ⋯ Ghrelin and GHRP-6 increase gastric emptying in diabetic mice with gastroparesis, perhaps by activating peripheral cholinergic pathways in the enteric nervous system.

Case ReportsIntrauterine midgut volvulus without malrotation: diagnosis from the 'coffee bean sign'.
Fetal midgut volvulus is quite rare, and most cases are associated with abnormalities of intestinal rotation or fixation. We report a case of midgut volvulus without malrotation, associated with a meconium pellet, during the gestation period. This 2.79 kg, 33-wk infant was born via a spontaneous vaginal delivery caused by preterm labor. ⋯ An emergency laparotomy revealed a midgut volvulus and a twisted small bowel, caused by complicated meconium ileus. Such nonspecific prenatal radiological signs and a low index of suspicion of a volvulus during gestation might delay appropriate surgical management and result in ischemic necrosis of the bowel. Preterm labor, specific prenatal sonographic findings (for example, the coffee bean sign) and bluish discoloration of the abdominal wall could suggest intrauterine midgut volvulus requiring prompt surgical intervention.
