Salmonella typhimurium was isolated from the feces of an alpaca suffering anorexia and weight loss. Multifocal necrotizing and suppurative hepatitis consistent with bacterial infection was found in the liver biopsies. Enteric salmonellosis may be associated with milder physical and clinicopathological changes in camelids than in other large animal species.

The successful cultivation of the virus of infectious hepatitis in chick embryo tissue culture and in the amniotic cavity of the embryonated hen's egg is supported by a comparison of the disease induced in volunteers by the cultivated virus with hepatitis without jaundice resulting from experimental infection with natural infectious hepatitis virus. Both types of viral preparations produced illnesses in comparable percentages of volunteers (83 and 75 per cent, respectively) after similar average periods of incubation (24.4 and 23.4 days, respectively) and of similar average duration (28.3 and 27.6 days, respectively). The disease could be divided in both groups of patients into a primary stage, followed after a short interval of relative well being by the secondary stage. The illnesses in both instances were characterized by anorexia, nausea, vomiting, enlarged, tender livers and abnormal liver function tests, and frequently temperature elevations. They differed in that jaundice was observed in 31 per cent of the cases resulting from infection with natural virus but not in any patients infected with the cultivated virus.

Since the discovery of hepatitis C virus (HCV) in 1989, significant advances have been made in our understanding of this important viral pathogen. Children at risk for HCV infection include recipients of potentially contaminated blood products and organ transplants, and infants born to HCV-infected mothers. Chronic HCV infection is usually asymptomatic in children but active hepatitis, cirrhosis and hepatocellular carcinoma can occur. The development of treatment strategies for chronic hepatitis C in children has directly evolved from clinical trials in adults. Sustained virologic response, defined by undetectable HCV RNA in serum 24 wk after completion of treatment, occurs in approximately 36% of children treated with conventional interferon alone and in about 50% of those given conventional interferon in combination with ribavirin. Pegylated interferon-based treatment regimens are better than those based on conventional interferon in adults but little is known about pegylated interferon in children. Factors associated with a favorable response to antiviral therapy in children are similar to those in adults and include infection with HCV genotype 2 or 3 and low pretreatment serum HCV RNA levels. Treatment related adverse events in children include 'flu-like' syndrome, fatigue, anorexia, weight loss, depression, anemia, leukopenia and thrombocytopenia.

Fulminant hepatic failure, which is represented by fulminant hepatitis, is fatal in most cases unless prompt liver transplantation is performed. Even if liver transplantation is performed, irreversible neurological damage is often complicated. In this case report, we describe two cases of fulminant hepatitis induced by acute hepatitis B virus infection, both of which were successfully rescued by living related liver transplantation without significant complications. The case 1 was a 45-year-old Japanese male. He complained general malaise and anorexia. His local physician diagnosed him as acute hepatitis B, and referred to our hospital. Due to severe coagulopathy, plasma exchange was performed 3 times. However, his hepatic coma progressed rapidly along with rapid decrease of both his direct/indirect bilirubin (D/T) ratio and serum blood urea nitrogen (BUN) levels. Living related liver transplantation was performed under the diagnosis of acute fulminant hepatitis B. The case 2 was a 34-year-old Japanese male. His complaints were fever and skin rush. He was referred to our hospital under the diagnosis of acute hepatitis B. On the second day after admission, he developed grade II hepatic coma, which deteriorated into grade III in spite of intensive therapy including plasma exchange. He also demonstrated rapid decrease of both D/T ratio and serum BUN level. Living related liver transplantation was performed on the next day. Both cases recovered without any evidence of neurological sequelae. In general, it is extremely difficult to rescue fulminant hepatitis by conservative treatments, particularly in cases with rapid progression. Although emergency liver transplantation may be an only option to rescue in such a case, living related liver transplantation has an advantage in view of urgent organ donation over cadeveric transplantation.

Trichloroethylene (TCE) is an organic solvent used in a variety of industries for more than 60 years. Several adverse events following acute or chronic exposure to trichloroethylene have been reported. However, TCE-induced hepatitis is very rare. We present the case of a 55-year old male who was presented with anorexia, fatigue and upper abdominal discomfort. Routine laboratory examination revealed marked elevation of liver enzyme values. All possible causes of hepatitis were ruled out. The patient has been working as a shoemaker, in a small room of a basement, with insufficient air-exchange; during the last 5 years he used daily a glue containing 1,1,1 trichloroethylene. The diagnosis of hepatitis was confirmed by liver biopsy. The offending agent was withdrawn. Three months later, he was "feeling well" and liver enzyme values had returned to normal. Six months after the initial biopsy, a second liver biopsy was performed and histology was markedly improved. Workers exposed to hazardous chemicals, such as trichloroethylene, must have periodic follow-up examinations. Good work practices are very important when using toxic substances. In patients whose initial diagnostic workout is negative for common causes of acute or chronic hepatitis, toxic causes should be considered, with emphasis on patient's job and working conditions.

A 36 years old male presented with anorexia, jaundice and ascites. He was suffering from acute viral E hepatitis. In view of ascites, he was investigated for associated asymptomatic chronic liver disease (CLD). The CLD was diagnosed as cirrhosis with autoimmune hepatitis and was treated with steroid with good response. He is maintaining good health with low dose steroid, on follow up for 1 year.

In 1996, a disease outbreak occurred at a captive breeding facility in Idaho, causing anorexia, dehydration, and diarrhea or sudden death in 72 of 110 Northern aplomado falcons (Falco femoralis septentrionalis) from 9 to 35 days of age and in 6 of 102 peregrine falcons (Falco peregrinus) from 14 to 25 days of age. Sixty-two Northern aplomado and six peregrine falcons died. Epidemiologic analyses indicated a point source epizootic, horizontal transmission, and increased relative risk associated with cross-species brooding of eggs. Primary lesions in affected birds were inclusion body hepatitis, splenomegaly, and enteritis. The etiology in all mortalities was determined by molecular analyses to be a new species of adenovirus distantly related to the group I avian viruses, serotypes 1 and 4, Aviadenovirus. In situ hybridization and PCR demonstrated that the virus was epitheliotropic and lymphotropic and that infection was systemic in the majority of animals. Adeno-associated virus was also detected by PCR in most affected falcons, but no other infectious agents or predisposing factors were found in any birds. Subsequent to the 1996 epizootic, a similar disease caused by the same adenovirus was found over a 5-year period in orange-breasted falcons (Falco deiroleucus), teita falcons (Falco fasciinucha), a merlin (Falco columbarius), a Vanuatu peregrine falcon (Falco peregrinus nesiotes), and gyrfalcon x peregrine falcon hybrids (Falco rusticolus/peregrinus) that died in Wyoming, Oklahoma, Minnesota, and California. These findings indicate that this newly recognized adenovirus is widespread in western and midwestern North America and can be a primary pathogen in different falcon species.

The present study reports the clinical, virological and pathological findings observed in a natural outbreak of highly pathogenic avian influenza in farmed commercial ducks. The ducks developed clinical signs, including mild respiratory distress, depression, mild diarrhoea, loss of appetite and increasing mortality (up to 12%). At necropsy, multifocal mottled necrosis was commonly found in the pancreas with splenomegaly, hepatomegaly, and swollen kidneys. Microscopically, there was necrotized pancreatitis and hepatitis, and lymphocytic meningoencephalitis and myocarditis. Influenza viral antigen was demonstrated in areas closely associated with histopathological lesion. Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all birds died within 24 h after inoculation. This is the first report of an outbreak of highly pathogenic avian influenza with clinical signs in commercial domestic ducks in South Korea.

Herbal remedies have become increasingly popular throughout the globe as a result of disappointment with conventional medicines and also of the alleged belief that herbal preparations are basically harmless. On the other hand, their effects can be exceedingly potent or even lethal if used improperly. Drugs and other chemicals account for less than 5% of cases of jaundice or acute hepatitis and smaller number of cases of chronic liver disease. Drug reactions can mimic any hepatobiliary disease, posing a diagnostic challenge for physicians and pathologists. Hepatotoxicity generally occurs after approximately 2 months of ingestion and consists of a non-specific hepatitis, which usually runs a benign course. Typical features include anorexia, nausea, abdominal pain, and jaundice associated with a marked elevation in serum aminotransferases. We present a case of acute hepatitis in a 70-year-old farmer, using Teucrium polium (golden germander) as hypoglycaemic aid. The patient presented only with jaundice, after 1 month's consumption of large quantities of this herb in a tea form.

Four female and 3 male Taita falcons (Falco fasciinucha) out of a breeding colony of 14 Taita falcons (7 pairs) died during the breeding season after showing lethargy and anorexia for 1 to 2 days. All animals were submitted for necropsy. Gross lesions in the female falcons were characterized by anemia secondary to marked hemorrhage into the ovary and oviduct, serofibrinous effusion into the cardioabdominal cavity and serosal petechiae. In addition, marked necrotizing splenitis and pulmonary hemorrhage were present. Histologically, the female falcons had mild necrotizing hepatitis with numerous intranuclear inclusion bodies and necrotizing splenitis with rare inclusion bodies. There were no gross lesions in the male falcons, and the histological lesions were characterized by urate deposition and rare intranuclear inclusion bodies in the renal tubular epithelial cells. Adenoviral particles were found by electron microscopy in the cloacal contents of the female Taita falcons but not in the male falcons. DNA in situ hybridization revealed widespread aviadenoviral nucleic acid within the nuclei of hepatocytes, renal tubular epithelial cells, and adrenal cells in the female falcons but no aviadenoviral nucleic acid in 1 male falcon and only a low quantity of adenoviral nucleic acid in the liver and kidney of another male Taita falcon. PCR amplified aviadenoviral DNA in the liver and intestine of all Taita falcons. The amplicons were sequenced, and the virus was identified as falcon adenovirus. The deaths of the female and male birds were attributed to the aviadenovirus infection.
