Notes

Simvastatin raises circulating endothelial progenitor cells and also inhibits the development regarding intracranial aneurysms in rodents with diet-induced hyperhomocysteinemia.
Siltuximab significantly influenced 9 of the analyzed parameters. Vedolizumab significantly influenced 8 of the analyzed parameters. Infliximab had the lowest impact of all the tested drugs, as it significantly influenced only two of the analyzed parameters. The study has proved that the impact of mAbs on the analyzed parameters can be significantly extended over time. This requires the monitoring of hematological parameters in the pig model even many weeks after administration of a drug in a relatively small dose.

The use of thiopurines is associated with multiple adverse effects including dose dependent cytopenias or idiosyncratic reaction. We report about a case of azathioprine related pancreatitis associated with polyarthralgia and panniculitis. Pancreatitis, polyarthritis and panniculitis (PPP) syndrome is an uncommon phenomenon which may accompany a number of pancreatic diseases including acute or chronic pancreatitis or pancreatic malignancy. To the best of our knowledge, this is the first report of Azathioprine related PPP syndrome. © Acta Gastro-Enterologica Belgica.We report the case of a hepatocellular adenoma associated with focal nodular hyperplasia and hepatic granulomas in a 30-yearsold woman. This association has rarely been described before but might be explained by underlying common pathophysiologic mechanisms. In this manuscript possible links between the three entities are discussed. © Acta Gastro-Enterologica Belgica.Background Enteropathy-associated T-cell lymphoma (EATL) is a rare type of gastrointestinal non-Hodgkin's Lymphoma. EATL with intracranial metastasis is even rarer. We report a case of EATL with intracranial metastasis. Case Presentation A 36-years old man presented with five weeks history of intractable diarrhea. Colonoscopy was normal, but abdominal computed tomography (CT) scan revealed mural thickening at duodenojejunal junction, and subsequent jejunofiberoscopy showed a circumferential ulceration at the jejunum. Histo-immunopathology confirmed the diagnosis of enteropathyassociated T-cell lymphoma (EATL) type II. His disease course proved to be aggressive and refractory to standard front-line chemotherapy, and eventually progressed through second-line salvage regimen with CNS and intracranial involvement. He died nine months after the initial diagnosis. Conclusion EATL with brain metastasis is a very rare occurrence with dismal prognosis. © Acta Gastro-Enterologica Belgica.We report the case of a 58 year old man with occult obscure gastro-intestinal bleeding (OGIB) without other significant symptoms, in which systemic localisation of follicular B-cell non-Hodgkin lymphoma was discovered trough capsule endoscopy. This case reflects the clinical significance of performing capsule endoscopy in patients with OGIB. © Acta Gastro-Enterologica Belgica.Patients with hepatic encephalopathy (HE) do not systematically receive priority on the waiting list for liver transplantation. In some patients with cirrhosis, excessive amounts of gut derived ammonia can bypass the liver parenchyma due to large spontaneous portosystemic shunts (SPSS) induced by portal hypertension. A similar but iatrogenic condition can occur after transjugular portosystemic shunt (TIPS) insertion. In these situations HE may develop and can become refractory to standard management. In patients with preserved liver function, embolization of large SPSS has been shown to control HE mostly without aggravation of other portal hypertensive complications. In case of post-TIPS HE endovascular shunt reduction is able to control refractory post-TIPS HE in the majority of the patients. New strategies to prevent post-TIPS, such as the use of controlled expansion endoprosthesis, are currently explored. © Acta Gastro-Enterologica Belgica.Background Self-inserted foreign rectal bodies are an infrequent occurrence, however they present a serious dilemma to the surgeon, due to the variety of objects, and the difficulty of extraction. The purpose of this study is to give a comprehensive review of the literature regarding the epidemiology, diagnostic tools and therapeutic approaches of foreign rectal body insertion. Methods A comprehensive systematic literature review on Pubmed/ Medline and Google for 'foreign bodies' was performed on January 14th 2018. A meta-analysis was carried out to evaluate the epidemiology, diagnostics and therapeutic techniques. 1,551 abstracts were identified, of which 54 articles were included. Results The motivation of foreign rectal body insertion is mostly sexual stimulation. Patients are typically young and predominantly male, with a male to female ratio of 61. Sexual devices (35.7%, n=108) and glass objects (17.5%, n=53) are the most commonly self-inserted rectal foreign bodies. Patient history should be taken sensitively after diagnostic evaluation and identification of the object. Removal was performed under general anesthesia in 45.2% (n=95) and sedation in 29.0% (n=61). BIBF1120 The total complication rate was described to be 30.4%. Conclusions Diagnostics must be performed with caution in order to rule out perforation and establish a treatment algorithm. Manual transanal extraction under sedation or general anesthesia may be performed in conjunction with cautious abdominal compression. Because of the variety of objects, i.e. in form and material, each case must be treated individually. Sometimes creativity and surgeon imagination may be required, although different algorithms have been established. © Acta Gastro-Enterologica Belgica.Colorectal cancer (CRC) has become the most common malignancy in our country. Routine screening colonoscopy is on the rise. With the recent advances in endoscopic treatment, many T1 colorectal carcinomas are now found and their percentage amenable to endoscopic resection has increased. Endoscopists and pathologists dealing with the steadily increasing number of excised colorectal polyps have to collaborate closely to optimize patient care. Therapeutic management of patients after endoscopic resection is based on precise histological criteria that determine the risk of metastasis and the need for complementary surgery. This paper summarizes the procedures for the macroscopic management of endoscopic excisions and presents the identified risk factors which should be included in a standardized pathology report. © Acta Gastro-Enterologica Belgica.
