A 67 year old male with postherpetic neuralgia complained of right anterior chest throbbing pain and also allodynia. We performed thoracic epidural block with 0.25% bupivacaine and 1% lidocaine. Oral carbamazepine and imipramine were also administred concomitantly. One month later, patient complained of fatigue, anorexia, pruritis, jaundice, and dark urine. Liver function test values were significantly elevated then. Therefore we removed the epidural catheter and ceased all medication. Liver function test values decreased rapidly after discontinuation of medication. Hepatitis might have developed as result of drugs administered and could have been prevented if the patient had been monitored with regular clinical laboratory follow up. The purpose of this case report is emphasize the importance of early regular laboratory test to detect any possible side effect that may occur by administration of drugs during treatment of chronic pain.

Ducklings collected from three farms, having history of rapid onset and spread of nerve signs including kick spasmodically with legs and opisthotonos, were pathologically, barteriologically, virologically examined. Grossly, multiple petechial to ecchymotic hemorrhages were detected in the swollen liver. Histopathologically, diffuse coagulative necrosis of hepatocytes was characteristic in acute cases. Chronic cases revealed marked bile duct hyperplasia rather than hepatocyte necrosis. Some of these cases exhibited multiple granulomas consisting of macrophages, heterophil, fibrin and necrotic cell debri. Filtered homogenate of livers sampled from ducklings caused embryo death with marked hemorrhage and swollen of liver after inoculation into chorioallantoic membrane. Three strains of Salmonella app.,S montevideo, S hadar, and S give, which were biochemically and serologically identified, weir isolated from ducklings of three farms, respectively. From these results, these ducklings were concurrently infected with duck hepatitis virus and Salmonella spp.

Imatinib mesylate is currently used as the first-line treatment for metastatic gastrointestinal stromal tumors (GISTs). Imatinib-induced hepatotoxicity in patients with GIST is very rare. Its features vary from subclinical elevation of serum aminotransferase to clinically apparent acute hepatitis, which is associated with immunologic reactions. Imatinib-induced hepatotoxicity with autoimmune-like features can be treated by the discontinuation of imatinib mesylate and the administration of oral steroids. Here, we report a case of late-onset imatinib-induced hepatitis with autoimmune-like features in a patient with metastatic GIST, which was improved by oral corticosteroids.

Serum hepatitis is still recognized as a major public health problem in many countries. The most common etiologies are acute viral hepatitis A and B, and hepatitis B virus (HBV) was known as the pathogen of serum hepatitis. since the HBV causes chronic hepatitis. HBV infection is hyperendemic in Korea. It is known that 8% and 1% of the Korean population is chronic carriers of HBV. The total number of 487 serum specimen (old people's home 190, causal ward-Daegu hope village 297) were collected at the laboratory of Department of Clinical Pathology of Daegu medical center. The laboratory tested the specimen to detect for hepatitis B surface antigen (HBsAg) and anti-HBs using reverse passive hemag-glutination (RPHA) and passive hemagglutination (PHA) method between April, 2011 and June, 2011. In one-step test, HBsAg and anti-HBs of Humasis were used. The positive rate for HBsAg was 6.80% (33/487), and the rate in male was 6.93% (19/274) higher than that of female 6.57% (14/213). In the positive rate of HBsAg by age group, the highest positive rate group was in the group of 40-49 years in male (12.0%), and 50-59 years in female (17.65 %). The overall positive rate for anti-HBs was 42.70% (208/487), showing the higher positive rate of 43.80% in male (120/274) than that of 41.30% (88/213) in female. The highest positive rate of anti-HBs in age group was the 40-49 years group in male (52.00%) and the group of under 29 in female (66.67%).

Alcoholic hepatitis is an acute and severe liver disease associated with high mortality rate. This study was conducted to develop the instrument of criterion for symptoms improvement after temperance. We made the symptoms improvement questionnaire for alcoholic hepatitis patients through reviewing traditional oriental medical literatures and got advices from the advisor committee with delphi technique. The advisor committee on this study was organized by 10 professors of internal medicine of oriental medical colleges nationwide. The questionnaire was composed of questions about 10 symptoms - fatigue, pain, anorexia, abdominal bloat, heaviness of the body, itch, nausea, sleep, dryness in the mouth and stools. We named it Alcoholic Hepatitis Symptoms Improvement Questionnaire(AHSIQ). We surveyed 65 male alcoholic hepatitis patients and checked liver function profile and AHSIQ before and after temperance four times for six weeks. As a result of factor analysis the scales of AHSIQ had content validity and construct validity. And internal consistency reliability was good(Cronbach's alpha=0.768-0.871). The total scale scores were statistically significant in gamma-GTP related validity. We suggest that AHSIQ would be effective for measuring symptoms improvement degree in alcoholic hepatitis patients through further investigations with larger clinical trials.

The studies of M. Colombo (1989) and W. Lange (1992) showed that 30~40% of people became chronic after suffering from hepatitis B virus (HBV) and C virus (HCV) infection, and about 50% of the chronic cases transformed into primary liver cancer. There have been few studies done in Mongolia on hepatitis infection among health professionals, particularly in nurses. In a study done by Chimedsuren (8), the study showed that 19.4% of people with identified surface hepatitis B antigen (HBsAg) and antibodies to hepatitis C virus and 8% of people with the identified nucleotide of RNA for the hepatitis C virus (polymerase chain reaction) had an acute form of hepatitis C. Studies on the hepatitis virus genome damaging effect on liver cells showed that genotype 8 (A, B, C, D, E, F, G, TTV) had the most damaging effect on liver cells (Hahn and Faeka, 2007). Several studies have shown a relationship between hepatitis B virus infection and a lack of compliance regarding safety regulations and rules by medical personnel. Results of a study from the Maternal and Child Health Research Center showed that tests done to detect hepatitis B virus antigen and antibodies to C virus did not reveal anything. Both antigen and antibodies in 69% cases did not show, and separately, B virus and antibodies to hepatitis C virus were identified in 13% and 9%, respectively. Results of the tests taken from health personnel in Shastin Central Hospital showed that in 76% of the cases, the B virus antigen with C virus antibodies was not identified. In 8% of the cases, the B virus antigen was present on its own. The combination of B the virus antigen and C virus antibodies were present in 8% of nurses and doctors, respectively. 82% of the cases had negative results for the detection of a combination of B virus antigen and C virus antibodies taken from health personnel from the State Central Clinical Hospital whereas the B virus antigen and C virus antibodies by themselves were present in 7% and 14% of the cases, respectively. Combined cases of the B virus antigen and C virus antibodies were identified in 4% of the personnel. Results of the tests taken from the health personnel in the Hospital of the Ministry of Justice and Internal Affairs showed that in 79% of the cases, the B virus antigen with C virus antibodies were not identified. Separately, the B virus and antibodies to hepatitis C virus were identified in 8% and 13% of the cases, respectively.

By radioimmunoassay, serologic markers of Hepatitis B Virus were studied in 44 patients with acute viral hepatitis, 10 patients with chronic persistent hepatitis, 10 patients with chronic active hepatitis, 44 patients with liver cirrhosis and 25 patients with primary hepato cellular carcinoma. The results were follows: 1) HBsAg was present in 77.2% of AVH, 40% of CPH, 80% of CAH, 55.1% of LC and 68 % of PHC. In this HBsAg positive groups, all but one in liver cirrhosis had Anti-HBc. 2) Anti-HBs was most commonly detected in CPR and accompanied by Anti-HBc except one case in AVH. 3) Anti-HBc was the only marker detected in 11.4% of AVH, 20% of CPH, 20% of CAH, 16.3% of LC and 8% of PHC. 4) HBeAg was most commonly found in HBsAg-positive CPH but Anti-HBe was most frequently detected in PHC. 5) The absence of HBV markers was noted in 2.3% of AVH, 10% of CPH, 8% of PHC except CAH and LC.

Hepatitis C virus (HCV) infection is a major medical challenge affecting around 200 million people worldwide. The main site of HCV replication is the hepatocytes of the liver. HCV is a positive enveloped RNA virus from the flaviviridae family. Six major HCV genotypes are implicated in the human infection. In developed countries the children are infected mainly through vertical transmission during deliveries, while in developing countries it is still due to horizontal transmission from adults. Minimal nonspecific and brief symptoms are initially found in approximately 15% of children. Acute and chronic HCV infection is diagnosed through the recognition of HCV RNA. The main objective for treatment of chronic HCV is to convert detected HCV viremia to below the detection limit. Children with chronic HCV infection are usually asymptomatic and rarely develop severe liver damage. Therefore, the benefits from current therapies, pegylated-Interferon plus ribavirin, must be weighed against their adverse effects. This combined treatment offers a 50-90% chance of clearing HCV infection according to several studies and on different HCV genotype. Recent direct acting antiviral (DAA) drugs which are well established for adults have not yet been approved for children and young adults below 18 years. The most important field for the prevention of HCV infection in children would be the prevention of perinatal and parenteral transmission. There are areas of focus for new lines of research in pediatric HCV-related disease that can be addressed in the near future.

Retinols are metabolized into retinoic acids by alcohol dehydrogenase (ADH) and retinaldehyde dehydrogenase (Raldh). However, their roles have yet to be clarified in hepatitis despite enriched retinols in hepatic stellate cells (HSCs). Therefore, we investigated the effects of retinols on Concanavalin A (Con A)-mediated hepatitis. Con A was injected into wild type (WT), Raldh1 knockout ($Raldh1^{-/-}$), $CCL2^{-/-}$ and $CCR2^{-/-}$ mice. For migration study of regulatory T cells (Tregs), we used in vivo and ex vivo adoptive transfer systems. Blockade of retinol metabolism in mice given 4-methylpyrazole, an inhibitor of ADH, and ablated Raldh1 gene manifested increased migration of Tregs, eventually protected against Con A-mediated hepatitis by decreasing interferon-${\gamma}$ in T cells. Moreover, interferon-${\gamma}$ treatment increased the expression of ADH3 and Raldh1, but it suppressed that of CCL2 and IL-6 in HSCs. However, the expression of CCL2 and IL-6 was inversely increased upon the pharmacologic or genetic ablation of ADH3 and Raldh1 in HSCs. Indeed, IL-6 treatment increased CCR2 expression of Tregs. In migration assay, ablated CCR2 in Tregs showed reduced migration to HSCs. In adoptive transfer of Tregs in vivo and ex vivo, Raldh1-deficient mice showed more increased migration of Tregs than WT mice. Furthermore, inhibited retinol metabolism increased survival rate (75%) compared with that of the controls (25%) in Con A-induced hepatitis. These results suggest that blockade of retinol metabolism protects against acute liver injury by increased Treg migration, and it may represent a novel therapeutic strategy to control T cell-mediated acute hepatitis.
