BACKGROUND/AIMS To estimate hepatocarcinogenesis rates in patients with hepatitis C virus (HCV)-related cirrhosis, an accurate prediction table was created. METHODS A total of 183 patients between 1974 and 1990 were assessed for carcinogenesis rate and risk factors. Predicted carcinogenesis rates were validated using a cohort from the same hospital(More)
BACKGROUND AND AIM Hepatitis C virus (HCV)-infected patients who responded to interferon (IFN) treatment with clearance of serum HCV RNA may rarely develop hepatocellular carcinoma (HCC). The aim of the present study was to elucidate the risk factors for liver carcinogenesis among such patients. METHODS In total, 126 patients with chronic hepatitis C(More)
Reactivation of a former hepatitis B virus (HBV) infection can be triggered by immunosuppressive therapy, diseases associated with an immunocompromised state, organ transplantation or the withdrawal of antiviral drugs. Despite the absence of such risk factors, a spontaneous reactivation of HBV replication occurred in two elderly patients with resolved or(More)
OBJECTIVE The aim of this study was to re-evaluate the upper limit of normal range (ULN) for serum alanine aminotransferase (ALT) in chronic hepatitis C (CH-C) patients who achieved sustained virological response (SVR) to interferon therapy. METHODS Enrolled in this study were 136 consecutive patients, 84 males and 52 females, mean age 52.1+/-14.8 years,(More)
UNLABELLED Thrombocytopenia is frequently found in patients with chronic liver disease, and associated with advanced fibrosis stage and with decreased liver function. Serum thrombopoietin (TPO) levels also decrease as the disease progresses from mild fibrosis to cirrhosis. On the other hand, platelet counts increase associated with improvement of fibrosis(More)
Satellite/terrestrial integrated mobile communication system (STICS) is an advanced system in which the satellite and terrestrial mobile systems share the frequency band and a mobile terminal can connect both of them. STICS is drawing attention as a robust system in terms of disaster and congestion. However, when the satellite link and the terrestrial link(More)
