We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was peformed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.

A hepatic angiomyolipoma is a rare benign tumor mainly composed of blood vessels, smooth muscle cells and fat cells in varying proportion. Hepatic angiomyolipoma is often misdiagnosed as a hepatocellular carcinoma in preoperative imaging work-up. To date, there has been little published data describing PET findings of hepatic angiomyolipoma. We report one case of hepatic angiomyolipoma that showed a high acetate and relatively low FDG uptake on PET images.

Acetaminophen (APAP) known as paracetamol is the main ingredient in Tylenol, which has analgesic and anti-pyretic properties. Inappropriate use of APAP causes major morbidity and mortality secondary to hepatic failure. Overdose of APAP depletes the hepatic glutathione (GSH) rapidly, and the metabolic intermediate leads to hepatocellular death. This article reviews the mechanisms of hepatotoxicity and provides an overview of current research studies. Pharmacokinetics including metabolism (activation and detoxification), subsequent transport (efflux)-facilitating excretion, and some other aspects related to toxicity are discussed. Nuclear factor erythroid 2-related factor 2 (Nrf2)-regulated gene battery plays a critical role in the multiple steps associated with the mitigation of APAP toxicity. The role of Nrf2 as a protective target is described, and potential natural products inhibiting APAP toxicity are outlined. This review provides an update on the mechanism of APAP toxicity and highlights the beneficial role of Nrf2 and specific natural products in hepatoprotection.

Cordyceps militaris (CM) has been used as antidiabetics, anticancer, endocrine and sexual functions enhancement in the traditional medicine. Water soluble fractions of CM showed cytotoxic activities on the three kinds of human cancer cell lines, stomachic adenocarcinoma(SNU-1), colorectal adenocarcinoma (SNU-C4), and hepatocellular carcinoma(SNH-354). Cytotoxic activity guided isolation and identification of active fractions afforded cordycepin as an active component.

Gilbert syndrome is the most common inherited disorder of bilirubin glucuronidation. It is characterized by intermittent episodes of jaundice in the absence of hepatocellular disease or hemolysis. Hereditary spherocytosis is the most common inherited hemolytic anemia and is characterized by spherical, osmotically fragile erythrocytes that are selectively trapped by the spleen. The patients have variable degrees of anemia, jaundice, and splenomegaly. Hereditary spherocytosis usually leads to mild-to-moderate elevation of serum bilirubin levels. Severe hyperbilirubinemia compared with the degree of hemolysis should be lead to suspicion of additional clinical conditions such as Gilbert syndrome or thalassemia. We present the case of a 12-year-old boy with extreme jaundice and nausea. The diagnosis of hereditary spherocytosis was confirmed by osmotic fragility test results and that of Gilbert syndrome by genetic analysis findings.

Comprehensive understanding of the natural course of chronic hepatitis B virus (HBV) infection is mandatory for the management and treatment of chronic hepatitis B, of which the natural course consists of immune tolerance, immune clearance, inactive carrier state, and reactivation phase. Evidence based medical approach is essential for the management of HBV carriers and treatment of active hepatitis to decrease risks of liver cirrhosis and hepatocellular carcinoma as well as to increase survival. In addition, education of patients or their parents are required to achieve a better therapeutic outcome and to prevent unconfirmed alternative medicine and anecdotal approaches.

This study was performed to evaluate the effects of high supplementary diet of vitamins, minerals, and polysaccharides on enhancing immunity and preventing from cancer in patients with hepatocellular carcinoma(hepatoma). Dietary therapy for patients was performed with dried yeast, wheat germ. Gonoderma extract, and vegetable juice. The vegetable juice was made of fresh green edible vegetables. Ten patients of total 30 patients were considered as improved state in tumor sizes, AFP, or symptoms. Most of patients complained of weight loss, fatigue, indigestion, anorexia before dietary therapy, but most of symptoms disappeared after dietary therapy. There was no significant side effects because of dietary therapy except for occasional slight diarrhea.

We investigated whether the CT images of hepatic lesions could be analyzed by computer-aided diagnosis (CAD) tool. We retrospectively reanalyzed 14 liver CT images (10 hepatocellular cancers and 4 benign liver lesions; patients who presented with hepatic masses). The hepatic lesions on CT were segmented by rectangular ROI technique and the morphologic features were extracted and quantitated using fractal texture analysis. The contrast enhancement of hepatic lesions was also quantified and added to the differential diagnosis. The best discriminating function combining the textural features and the values of contrast enhancement of the lesions was created using linear discriminant analysis. Textural feature analysis showed moderate accuracy in the differential diagnosis of hepatic lesions, but statistically insignificant. Combining textural analysis and contrast enhancement value resulted in improved diagnostic accuracy, but further studies are needed.

Sepsis remains the leading cause of morbidity and mortality following trauma. Although hepatocellular dysfunction occurs during trauma and sepsis. the mechanism responsible for this remains unclear. We investigated the role of Kupffer cells in the alterations in microsomal drug metabolizing function during trauma and sepsis. Rats were subjected to trauma by femur fracture (FFx). After 72h, polymicrobial sepsis was induced by cecal ligation and puncture(CLP). (omitted)
