Implementing an electromagnetic tracking navigation system improves the precision of endoscopic transgastric necrosectomy in an ex vivo model.

Endoscopic transgastric necrosectomy is crucial in the management of complications resulting from necrotizing pancreatitis. However, both real-time and visual-spatial information is lacking during the procedure, thereby jeopardizing a precise positioning of the endoscope. We conducted a proof-of-concept study with the aim of overcoming these technical difficulties.

Risks and benefits of TIPS in HCC and other liver malignancies: a literature review.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is a well-validated treatment option for clinically significant portal hypertension (CSPH) in the context of liver cirrhosis. Its high efficacy and safety in the management of treatment-refractory ascites and variceal bleeding have been extensively proven. Contraindications for TIPS include severe right heart failure, hepatic encephalopathy, and sepsis.

Pembrolizumab-induced acute exacerbation of hepatitis D.

A 55-year-old man was treated with combined immunochemotherapy (pembrolizumab, carboplatin and pemetrexed) because of non-small cell lung cancer (NSCLC). In addition, the patient had a medical history of chronic hepatitis B/D virus infection and cystic echinococosis. The viral hepatitis co-infection was treated with pegylated interferon (IFN)-alpha and tenofovir in the past (non-response after treatment), followed by maintenance therapy with tenofovir.

Delineation of Subregions in the Early Postnatal Human Cerebellum for Design-Based Stereologic Studies.

Recent design-based stereologic studies have shown that the early postnatal (<1 year of age) human cerebellum is characterized by very high plasticity and may thus be very sensitive to external and internal influences during the first year of life. A potential weakness of these studies is that they were not separately performed on functionally relevant subregions of the cerebellum, as was the case in a few design-based stereologic studies on the adult human cerebellum. The aim of the present study was to assess whether it is possible to identify unequivocally the primary, superior posterior, horizontal, ansoparamedian, and posterolateral fissures in the early postnatal human cerebellum, based on which functionally relevant subregions could be delineated.
