Elevated paraneoplastic hypercholesterolemia in a case of hepatoid adenocarcinoma of the stomach with liver metastasis.

A 67-year-old man was admitted to our hospital because of a large liver tumor revealed by ultrasonography. Laboratory data showed increased serum levels of alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP), which are tumor markers for hepatocellular carcinoma. In addition, the serum cholesterol level was extremely high.

Persistence of pandemic influenza H1N1 virus in young patients after oseltamivir therapy in the 2009-2010 season: a comparison with seasonal H1N1 with or without H275Y mutation.

Comparison of the viral persistence of pandemic H1N1 (H1N1pdm) and seasonal H1N1 with or without H275Y mutation after oseltamivir therapy has not been adequately done. Virus was isolated before and on days 4-6 from the start of oseltamivir treatment for 158 cases of seasonal (2007-2008 and 2008-2009 seasons) or pandemic (2009-2010 season) H1N1 influenza. Sequence analysis was done for each season and NA inhibition assay (IC(50)) was done in the 2009-2010 season.
