Hepatocellular adenomas (HCA) may present with spontaneous haemorrhage and rupture. The aim of this study was to assess management in 22 patients treated for haemorrhage and/or rupture of HCA. ⋯ HCA with haemorrhage and/or rupture does not necessarily require immediate liver resection. Conservative treatment is justified in stable patients. In case of an instable patient with or without hemoperitoneum, laparotomy with packing or selective embolisation can stop the bleeding.

Randomized Controlled Trial Comparative Study
Comparison of outcome in patients with cirrhosis and ascites following treatment with albumin or a synthetic colloid: a randomised controlled pilot trail.
The question of which colloid (albumin or synthetic colloids) used for plasma expansion following paracentesis or other complications requiring fluid loading in patients with cirrhosis remains controversial. ⋯ In patients with cirrhosis and ascites, human albumin appears to be more effective in preventing liver-related complications than synthetic colloid. This may be associated with decreased hospital costs.

Comparative Study
Differential caspase-9-dependent signaling pathway between tumor necrosis factor receptor- and Fas-mediated hepatocyte apoptosis in mice.
Two apoptosis signaling pathways, which are used by different cell types, are identified. The activation of caspases is critical for the apoptosis process. The aim of this study was to investigate the effects of the caspase-9 inhibitor Ac-LEHD-CHO on tumor necrosis factor receptor (TNFR)- and Fas-mediated hepatocyte apoptosis in vivo, in order to evaluate the similarities and distinctions between TNFR- and Fas-mediated signaling pathways. ⋯ Fas may rely on both caspase-8 activation (extrinsic pathway) and mitochondria (intrinsic pathway) to activate caspase-3. If the mitochondria-dependent pathway is blocked, the other pathway can compensate. In contrast, TNFR may mediate hepatocellular apoptosis mainly through the mitochondria-mediated caspase-9 activation pathway alone.

Expression alteration of Glypican-3 (GPC3) is associated with several malignancies and has been identified as an overexpressed gene in hepatocellular carcinoma (HCC). In this study GPC3 expression in intrahepatic chanlangiocarcinoma (ICC), gallbladder cancer and HCC was quantitatively detected. ⋯ The different expression patterns of GPC3 in HCC and ICC suggested that it might play a different role in theses tumors and could serve as a biomarker for differential diagnosis of HCC and ICC.
