Gia L. Tyson, Hashem B. El‐Serag – 12 April 2011 – Cholangiocarcinoma (CC) is the second most common primary hepatic malignancy after hepatocellular cancer. CC accounts for approximately 10%‐25% of all hepatobiliary malignancies. There are considerable geographic and demographic variations in the incidence of CC. There are several established risk factors for CC, including parasitic infections, primary sclerosing cholangitis, biliary‐duct cysts, hepatolithiasis, and toxins.

Giliola Calori, Guido Lattuada, Francesca Ragogna, Maria Paola Garancini, Paolo Crosignani, Marco Villa, Emanuele Bosi, Giacomo Ruotolo, Lorenzo Piemonti, Gianluca Perseghin – 12 April 2011 – A fatty liver, which is a common feature in insulin‐resistant states, can lead to chronic liver disease. It has been hypothesized that a fatty liver can also increase the rates of non–hepatic‐related morbidity and mortality.

Markus Casper, Frank Grünhage, Frank Lammert – 7 April 2011 – To identify susceptibility variants for hepatitis B virus (HBV)‐related hepatocellular carcinoma (HCC), we conducted a genome‐wide association study by genotyping 440,794 SNPs in 355 chronic HBV carriers with HCC and 360 chronic HBV carriers without HCC, all of Chinese ancestry.

Bruno Christ, Peggy Stock, Matthias M. Dollinger – 7 April 2011 – Cancer stem cells (CSCs) are generally dormant or slowly cycling tumor cells that have the ability to reconstitute tumors. They are thought to be involved in tumor resistance to chemo/radiation therapy and tumor relapse and progression. However, neither their existence nor their identity within many cancers has been well defined.

Malcolm R. Alison, Wey‐Ran Lin – 7 April 2011 – The liver and exocrine pancreas share a common structure, with functioning units (hepatic plates and pancreatic acini) connected to the ductal tree. Here we show that Sox9 is expressed throughout the biliary and pancreatic ductal epithelia, which are connected to the intestinal stem‐cell zone. Cre‐based lineage tracing showed that adult intestinal cells, hepatocytes and pancreatic acinar cells are supplied physiologically from Sox9‐expressing progenitors.

Piotr Czubkowski, Mike Williams, Seema Bagia, Deirdre Kelly, Girish Gupte – 5 April 2011 – Four children who underwent ABO‐compatible combined liver and small bowel transplantation developed severe immune‐mediated hemolytic anemia. The main management strategies were early and aggressive treatment with steroids, the introduction of rituximab (an anti‐CD20 monoclonal antibody), and the use of plasma exchange together with compatible but minimal blood transfusions. Three of the 4 children developed thrombi in the major vessels.
