  • Proton Pump Inhibitors Use and Increased Risk of Spontaneous Bacterial Peritonitis in Cirrhotic Patients: A Retrospective Cohort Analysis

  • Acute Upper Gastrointestinal Bleeding: Less Severe Bleeding in More Frail and Older Patients, Comparison Between Two Time Periods Fifteen Years Apart

    Acute upper gastrointestinal bleeding (AUGIB) remains a common medical emergency with considerable morbidity and mortality. The aim of this study was to describe the patient characteristics, diagnoses and clinical outcomes of patients presenting with AUGIB nowadays and compare these with those of patients 15 years ago.

  • The Incidence of Venous Thromboembolism and Practice of Deep Venous Thrombosis Prophylaxis Among Hospitalized Cirrhotic Patients

    Patients with liver cirrhosis have altered hepatic synthetic functions which theoretically result in reduced levels of pro-and anti-coagulant factors as well as thrombocytopenia. Initially, cirrhotic patients were thought to be at an increased risk of bleeding and a reduced risk of thrombosis.

  • Clinical Outcomes and Predictors of Thirty-Day Readmissions of Hypertriglyceridemia-Induced Acute Pancreatitis

    Hypertriglyceridemia (HTG) is a well-established cause of acute pancreatitis often leading to significant morbidity, mortality, and healthcare burden. This study aimed to describe the rate, reasons, and predictors of HTG-induced acute pancreatitis (HTG-AP) in the USA.

  • Corticosteroid and Biologic Use Not Associated With Adverse Outcomes for Inflammatory Bowel Disease Patients Hospitalized With COVID-19

Flood Syndrome
Flood syndrome refers to the exsanguination of ascitic fluid following the spontaneous rupture of an umbilical hernia, and is a rare complication of liver cirrhosis with ascites. In this case report, we describe a 67-year-old patient with Flood syndrome who was initially managed conservatively in a community hospital run by primary care physicians, prior to transfer to a tertiary hospital for specialist surgical review and management.
