Unusual Diaphragmatic Hernias Mimicking Cardiac Masses

Hiatal hernia and Morgagni hernia are sorts of diaphragmatic hernias that are rarely detected on transthoracic echocardiography. Although echocardiographic findings have an important role for differential diagnosis of cardiac masses, we often might overlook diaphragmatic hernia. We report three cases of diaphragmatic hernias having specific features. The first case is huge hiatal hernia that encroaches left atrium with internal swirling flow on transthoracic echocardiography. The second case is a hiatal hernia that encroaches on both atria, incidentally detected on preoperative echocardiography. The third case is Morgagni hernia which encroaches on the right atrium only. So, we need to consider possibility of diaphragmatic hernia when we find a cardiac mass with specific echocardiographic features.

A Case of Gastric Ulcer Bleeding by Direct Connection to the Splenic Artery

Gastric ulcer bleeding is commonly encountered in emergency situations for gastroenterologist. Usually depth of gastric ulcer does not exceed the muscle layer. We report a case of a 67-year-old male with massive gastric ulcer bleeding caused by direct connection to the splenic artery. Bleeding control was not effectively performed by endoscopy due to massive bleeding with unstable vital sign. Angiography for embolization was performed. Active extravasation of contrast agents at the splenic artery stenosis was noted on splenic arteriogram. Bleeding stopped after embolization with histoacryl and lipiodol was successfully performed. After 1 month, complete ulcer healing was confirmed by follow up endoscopy. There was no evidence of invasive disease on biopsy.

Reactivation of Hepatitis B Virus Following Anti-Tumor Necrosis Factor-alpha Therapy

Anti-tumor necrosis factor (TNF)-alpha therapy is being increasingly used to treat several rheumatic diseases and inflammatory bowel diseases. However, treatment with anti-TNF-alpha therapy of patients with a concurrent hepatitis B virus (HBV) or hepatitis C virus (HCV) infection can promote viral reactivation and potentially fatal liver failure. The medical records of 176 patients who had been treated with an anti-TNF-alpha therapy at single center from January 2010 to December 2012 were retrospectively analyzed. Of the 176 patients, the hepatitis B surface antigen (HBsAg) status of 114 (64.8%) were tested at the baseline. Five (4.4%) of them were HBsAg-positive, and 109 (95.6%) were negative. Only 10 of the HBsAg-negative patients (9.2%) were checked for hepatitis B core antigen. Ninety-one patients were checked for anti-HCV, and two (2.2%) were positive. After their anti-TNF-alpha therapy, HBV reactivation was confirmed in two patients. The reactivation of HBV after the anti-TNF-alpha therapy was observed in the HBsAg-positive patients.
