Treatment of colonic varices and gastrointestinal bleeding by recanalization and stenting of splenic-vein-thrombosis: A case report and literature review.

BACKGROUND: Splenic vein thrombosis is a known complication of pancreatitis. It can lead to increased blood flow through mesenteric collaterals. This segmental hypertension may result in the development of colonic varices (CV) with a high risk of severe gastrointestinal bleeding. While clear guidelines for treatment are lacking, splenectomy or splenic artery embolization are often used to treat bleeding. Splenic vein stenting has been shown to be a safe option. CASE SUMMARY: A 45-year-old female patient was admitted due to recurrent gastrointestinal bleeding. She was anemic with a hemoglobin of 8.0 g/dL. As a source of bleeding, CV were identified. Computed tomography scans revealed thrombotic occlusion of the splenic vein, presumably as a result of a severe acute pancreatitis 8 years prior. In a selective angiography, a dilated mesenterial collateral leading from the spleen to enlarged vessels in the right colonic flexure and draining into the superior mesenteric vein could be confirmed. The hepatic venous pressure gradient was within normal range. In an interdisciplinary board, transhepatic recanalization of the splenic vein via balloon dilatation and consecutive stenting, as well as coiling of the aberrant veins was discussed and successfully performed. Consecutive evaluation revealed complete regression of CV and splenomegaly as well as normalization of the red blood cell count during follow-up. CONCLUSION: Recanalization and stenting of splenic vein thrombosis might be considered in patients with gastrointestinal bleeding due to CV. However, a multidisciplinary approach with a thorough workup and discussion of individualized therapeutic strategies is crucial in these difficult to treat patients.

Management of suspected and known eosinophilic esophagitis-a nationwide survey in Austria.

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease of the esophagus with increasing incidence and dysphagia as the main symptom. The management of suspected or known EoE by Austrian endoscopists has not been investigated yet. METHODS: A web-based survey with 13 questions about the management of EoE was sent to endoscopists via the Austrian Society of Gastroenterology and Hepatology (ÖGGH). RESULTS: A total of 222 endoscopists (74% gastroenterologists, 23% surgeons, and 2% pediatricians; 68% working in a hospital) from all 9 states participated. In patients with dysphagia but a normal appearing esophagus, 85% of respondents reported always taking biopsies; however, surgeons were less likely to obtain biopsies compared to gastroenterologists ("always" 69% vs. 90%, "sometimes" 29% vs. 10%, "never" 2% vs. 0%, p < 0.001). The approved budesonide orodispersible tablet is the preferred first-line drug used in EoE, ahead of proton pump inhibitors (PPI). Only 65% of participants monitor the patients by endoscopy and histology after 12 weeks of induction therapy, 26% do not continue maintenance therapy, and 22% monitor patients only when symptomatic. CONCLUSION: The vast majority of Austrian endoscopists adhere to the European and US guidelines in cases of suspected EoE. In contrast, despite the chronic disease course, a significant percentage of providers indicate not to use maintenance therapy and monitor the patients routinely.

Agenesis of the dorsal pancreas: a very rare entity causing diabetes mellitus.

Dorsal pancreatic agenesis is a very rare pancreatic developmental anomaly resulting in missing corpus and cauda of the pancreas. Due to improvements and more widespread use of advanced radiological techniques like CT or MRI, the possibility of finding this disorder is growing. Thus, this rare congenital condition, as well as a pancreas divisum and pseudo-agenesis secondary to chronic pancreatitis, must be considered in the differential diagnosis. Although most of the patients seem to be asymptomatic, abdominal pain and pancreatitis may develop. Moreover, this entity should be known by the treating physician, as these patients are at a high risk of developing diabetes mellitus during their lifetime. Herein, we present the case of a 65-year-old woman with complete agenesis of the dorsal pancreas. The patient was hospitalized due to weight loss, abdominal discomfort, and diabetes mellitus type 2.

Life-threatening heat stroke presenting with ST elevations: a report of consecutive cases during the heat wave in Austria in July 2013.

Heat stroke is a life-threatening condition due to an acute thermoregulatory failure during exposure to high environmental temperatures. We report a series of four cases (three exertional, one classic heat stroke) during the heat wave of July 2013 in Austria. All of them presented with a core temperature > 41 °C, central nervous dysfunction, acute respiratory and renal failure, disseminated intravascular coagulation, rhabdomyolysis, and severe electrocardiographic changes, two cases even mimicking ST-elevation myocardial infarction. The patients were cooled to normal temperature with the "Arctic sun" external cooling system within hours. Electrocardiographic changes resolved quickly. All patients primarily recovered from multiple organ dysfunction and could be discharged from intensive care unit. Unfortunately, the two elder patients died 1 week and 5 weeks later because of late complications.

Leptospirosis and renal failure: a case series.

Leptospirosis is a ubiquitous and potentially fatal zoonosis with protean manifestations. Human infection commonly occurs through contact with contaminated water or soil. In developed countries, leisure or household activities are increasingly associated with the disease. Within few months, we encountered five unrelated and autochthonous cases of severe leptospirosis, three of them requiring interim dialysis. In this case series, we present their clinical course. Furthermore, we provide an overview on the spectrum of organ involvement, with an emphasis on kidney injury, and comment on pitfalls in establishing the diagnosis. The considerable variance in presentation-with admissions both to internal and neurological units-emphasises the high index of suspicion required to arrive at the right diagnosis, particularly in countries of perceived low risk such as Austria.

Three solid malignancies and a myelodysplastic syndrome with a protracted course after kidney transplantation.

Although a well-known complication after transplantation, multiple non-skin malignancies within a patient are rare. We report on a kidney transplant recipient who over the course of 20 years developed breast cancer twice, a uroepithelial carcinoma, and myelodysplasia transforming into acute leukaemia. Breast cancer was treated as usual. The transitional cell carcinoma was managed with partial cyst ureterectomy with transposition of the native ureter to the graft. Withdrawal of immunosuppression followed under a "watchful waiting" regime. In conclusion, alertness is requested regarding development of malignancies. Creative solutions are necessary in the management of such patients. Under exceptional circumstances, withdrawal of immunosuppression may be an option.
