Retroperitoneal cecal volvulus: a complication of a rare internal hernia - a case report.

Introduction and importance: The foramen of Winslow hernia (FWH) is a rare type of internal hernia. In one-third of cases, the cecum was found in the lesser sac. More rarely, the herniated cecum might be volvulated, which represents 1-1.5% of the causes of intestinal obstruction. Once diagnosed, surgical reduction and/or resection of the nonviable herniated bowel is crucial for a positive outcome. Case presentation: The authors report a case of retroperitoneal cecal volvulus that complicated FWH in a patient with a history of laparoscopic cholecystectomy. Clinical discussion: A delay in the diagnosis is associated with high morbidity and even higher mortality. Because of lacking a consensus, the treatment of FWH depends on the team's surgical experience. Conclusion: Reporting this case will help us to keep in mind this differential diagnosis while treating patients in our daily practice.

C. perfringens Blood Stream Infection due to Nontransmural Ischemia of the Esophagus, Stomach, and Left Colon: Case Report.

We report the case of a 74-year-old female with abdominal pain, tarry stools, and tachycardia. Previous history included diabetes mellitus with micro- and macroangiopathy. Imaging revealed portal gas, left sided colitis, and emphysematous gastritis, besides severe atherosclerosis with subtotal celiac trunk occlusion and moderate stenosis of the inferior mesenteric artery. Upper endoscopy revealed findings consistent with focal necrotizing gastritis at the greater curvature and acute esophageal necrosis. Blood cultures immediately grew Clostridium perfringens. The patient was treated with broad spectrum antibiotics and was discharged after 21 days in the hospital. This case demonstrates the rare coincident occurrence of nontransmural ischemia of the left colon, the esophagus, and the stomach as a result of low-flow circulatory compromise, which then precipitated C. perfringens associated emphysematous gastritis and blood stream infection.

Albumin-binding function is reduced in patients with decompensated cirrhosis and correlates inversely with severity of liver disease assessed by model for end-stage liver disease.

BACKGROUND: Human serum albumin has multiple functions, the most important being maintaining colloid osmotic pressure, ligand binding and transport. In liver failure, an impaired binding of endogenous substances and drugs can be observed. The aim of this study was to investigate the relationship between the severity of liver disease and an impaired albumin binding. METHODS: In 44 patients with decompensated liver cirrhosis, Child-Turcotte-Pugh and model for end-stage liver disease scores were assessed and the site II-specific albumin-binding function (albumin-binding capacity) was characterized. Briefly, the unbound amount of diazepam site ligand Dansylsarcosine in a sample was determined and compared with the unbound amount in a reference albumin solution (=100%). RESULTS: Thirty-two out of 44 of the patients presented with Child-Turcotte-Pugh class C, the median Child-Turcotte-Pugh score was 10 [6-13 (min-max)], median model for end-stage liver disease score was 21 (8-40) and the median albumin-binding capacity was 63 (24-91)% compared with healthy controls 98 (95-106)% (P<0.001). Albumin-binding capacity was found to be strongly correlated to model for end-stage liver disease (r=0.783; P<0.001). CONCLUSIONS: An impaired albumin-binding function of a site II-specific marker in decompensated liver cirrhosis was found to be correlated to the severity of the liver disease.
