    Patient 1 was an 80-year-old man with recurrent hepatocellular carcinoma (HCC). Previously, his HCC had been treated with transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) using a monopolar electrode. In 2013, a pacemaker was implanted to treat complete atrioventricular block. In April 2014, he underwent RFA using two bipolar electrodes to treat recurrent HCC. During ablation, the pacing mode was changed from VVI to VOO. Patient 2 was an 86-year-old man who received a pacemaker for complete atrioventricular block in 2003. In 2014, he underwent TACE for HCC followed by RFA using two bipolar electrodes. The pacing mode (VDD) was not changed during ablation. In both patients, we did not observe any abnormal waveforms with electrocardiographic monitoring or pacing failure during ablation. These results suggest that treating HCC using RFA with bipolar electrodes is safe in patients with pacemakers.

    A 67-years-old male was admitted due to serious liver dysfunction. He was diagnosed as having severe acute hepatitis A by detection of IgM anti-HAV. Serum transaminase level gradually decreased, but jaundice did not resolve enough. On 32nd hospital day, hemoglobin decreased remarkably without any finding of gastrointestinal bleeding. There were no abnormal findings on reticulocyte count and bone marrow examination. Serum LDH level elevated again and haptoglobin remained low level. We diagnosed his condition as hemolytic anemia with dysfunction of erythropoiesis. Anemia improved by blood transfusion without using steroid agents. However, on 37th hospital day, he developed high fever. Laboratory test disclosed cytomegalovirus (CMV) antigen was positive. We administered ganciclovir with effect. Since IgG anti-CMV was positive on admission, we concluded that it was a CMV reactivation accompanied with acute hepatitis A.
