Colonic lipoma covered by hyperplastic epithelium: Case report.

Colonic lipomas are submucosal nonepithelial tumors covered by intact or eroded mucosa. In rare cases, alterations in the mucosa covering a lipoma include hyperplasia, adenoma, atrophy, ulceration, and necrosis. Here, we report a case of a colonic lipoma covered by hyperplastic epithelium in a 68-year-old woman.

Boerhaave's syndrome during bowel preparation with polyethylene glycol in a patient with postpolypectomy bleeding.

Boerhaave's syndrome is spontaneous rupture of the esophagus, a rare condition with high mortality that occurs most often after forceful vomiting. Polyethylene glycol (PEG) solution is the most common preparation used for colonoscopy. Since large volumes have to be ingested, PEG may induce severe vomiting or retching.

Serum prohepcidin levels are lower in patients with atrophic gastritis.

Background/Aim. Hepcidin, an iron regulatory hormone, is increased in response to inflammation and some infections. We investigated the relationships among serum prohepcidin, iron status, Helicobacter pylori infection status, and the presence of gastric mucosal atrophy.

Usefulness of the Bedside Index for severity in acute pancreatitis in the early prediction of severity and mortality in acute pancreatitis.

Objectives: The aim of this study was to evaluate the usefulness of the Bedside Index for Severity in Acute Pancreatitis (BISAP) in the early prediction of severity and mortality in AP.

Methods: The medical records of all patients with acute pancreatitis (AP) admitted to our institution between January 2008 and July 2010 were reviewed retrospectively. Severe AP was defined as the persistence of organ failure for more than 48 hours.

[A case of hepatocellular carcinoma combined with liver abscess].

Hepatocellular calcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer-related deaths worldwide. It is important to diagnose HCC exactly before management is attempted. But, the clinical presentations and radiologic findings of liver abscess, HCC, and metastatic tumor to the liver may be quite similar, and procedures such as serum tumor marker assay, computerized tomography, and ultrasonography of the liver cannot make a specific diagnosis.
