[Comparison on Oral versus Intravenous Proton Pump Inhibitors for Prevention of Bleeding after Endoscopic Submucosal Dissection of Gastric Lesions].

Background/aims: Although intravenous proton pump inhibitor (PPI) has been used for the prevention of post endoscopic submucosal dissection (ESD) bleeding, the route of administration has not been confirmed. The aim of the present study was to compare the efficacy of intravenous and oral PPI administration for the prevention of delayed post ESD bleeding.

Methods: Total 166 consecutive patients were randomly assigned to 30 mg lansoprazol twice a day (PO group) and 120 mg pantoprazole intravenous injection (IV group) for 48 hours.

[Trends in the eradication rates of Helicobacter pylori infection in Daegu and Gyeongsangbuk-do, Korea: multicenter study over 13 years].

Background/aims: The eradication rates of Helicobacter pylori infection have been reported to have decreased over the years due to antibiotics resistance. The aim of this study is to investigate the trend of eradication rates of first-line triple therapy for H. pylori over the past 13 year period, and to evaluate factors affecting H.

Improvement in left ventricular systolic dyssynchrony in hypertensive patients after treatment of hypertension.

Background And Objectives: Left ventricular (LV) dyssynchrony has been commonly detected among hypertensive patients with normal LV systolic function and no evidence of congestive heart failure. The purpose of our study was to assess the changes in LV systolic dyssynchrony (SDS(LV)) among hypertensive patients after antihypertensive treatment, and to determine the relationship between SDS(LV) and other conventional echocardiographic parameters.

Subjects And Methods: Forty one hypertensive patients with normal LV ejection fraction were enrolled.
