Cervical tuberculous lymphadenitis is mainly diagnosed by analyzing tissue samples obtained by fine-needle aspiration (FNA). However, some cases remain diagnostic challenges even after polymerase chain reaction analysis of FNA specimens. To delineate differences between cases that are relatively easy to diagnose and those for which diagnosis is difficult,(More)
Klebsiella pneumoniae (KP) is the most common cause of pyogenic liver abscess in eastern Asia. KP liver abscess commonly presents as a single large abscess with a predominantly solid consistency. It is sometimes unsuitable for percutaneous catheter drainage because of the poorly liquefied contents. Antibiotic therapy alone may raise a probability of(More)
AIM To investigate the therapeutic efficacy of short-term, multiple daily dosing of intravenous interferon (IFN) in patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B. METHODS IFN-beta was intravenously administered at a total dose of 102 million international units (MIU) over a period of 28 d in 26 patients positive for HBeAg and(More)
Monoclonal antibody (mAb.) against liver ferritin was produced by immunization of human liver ferritin. Using this mAb., an RPHA system for measurement of the serum ferritin level was established. This system had a good correlation coefficient (0.8625) with the RIA method and could measure levels of more than 2 ng/ml. The reactivity to heart ferritin in(More)
AIM To investigate the possibility of shortening the duration of peginterferon (Peg-IFN) plus ribavirin (RBV) combination therapy by incorporating interferon-β (IFN-β) induction therapy. METHODS A one treatment arm, cohort prospective study was conducted on seventy one patients. The patients were Japanese adults with genotype 1b chronic hepatitis C,(More)
A 68-year-old man underwent cholecystectomy and choledochoduodenostomy for biliary obstruction and nephrectomy for a renal tumor. Based on clinical and histopathologic findings, autoimmune pancreatitis (AIP) was diagnosed. The renal tumor was diagnosed as a renal cell cancer. Steroid therapy was started and thereafter pancreatic inflammation improved. Five(More)
Mesenteric panniculitis is a non-specific inflammatory disorder affecting adipose tissues of the mesentery. Mesenteric adipose tissues contain macrophages and other inflammatory cells, which may secrete tumor necrosis factor α, interleukin (IL)-1, and IL-6. These cytokines collect into the portal vein and thereby flow into the liver, possibly influencing(More)
We describe a rare case of thyroidal Epstein–Barr virus-positive diffuse large B-cell lymphoma of the elderly (EBV+DLBCLe) in which diagnosis was difficult and spontaneous esophageal fistula developed. A 79-year-old woman presented with acute swelling of the anterior neck with tenderness, general fatigue, and continual fever. Malignant lymphoma of the(More)
AIM Initial hepatitis C virus (HCV) RNA reduction was investigated as a potential index for sustained virological response (SVR) in the treatment of interferon (IFN)-β followed by peginterferon plus ribavirin (PEG IFN/RBV). METHODS The treatment course was retrospectively analyzed in 64 genotype 1b patients with a HCV RNA level of 5.0 logIU/mL or higher.(More)
