| hepatitis externa | Inflammation of the serous, or peritoneal, covering of the liver. Synonym: hepatic capsulitis, hepatitis externa, hepatoperitonitis. Origin: peri-+ G. Hepar, liver, + -itis, inflammation (05 Mar 2000) |
|---|---|
| hepatitis, infectious | See Hepatitis A. (12 Dec 1998) |
| hepatitis, infectious canine | An adenovirus infection causing fever, oedema, vomiting, and diarrhoea in dogs, especially puppies. In foxes it causes acute encephalitis with convulsions, paralysis, coma, and death. (12 Dec 1998) |
| hepatitis non-A, non-B | <virology> A virus somewhat similar in size to Hepatitis A but has no antigenic cross reaction with either A or B. Many of the cases are in fact hepatitis C and this was the old term for hepatitis C. (20 Sep 2002) |
| hepatitis, toxic | Acute hepatitis caused by true hepatotoxins such as amanita phaloides toxin, carbon tetrachloride, yellow phosphorus, and a variety of drugs. (12 Dec 1998) |
| hepatitis, viral | Liver inflammation caused by viruses. Specific hepatitis viruses have been labelled a, b, c, d, e, f, and g. While other viruses, such as the mononucleosis (epstein-barr) virus and cytomegalovirus, can also cause hepatitis, the liver is not their primary target. (12 Dec 1998) |
| hepatitis, viral, animal | Viral hepatitis in animals. (12 Dec 1998) |
| hepatitis, viral, human | Viral hepatitis in man. (12 Dec 1998) |
| hepatitis viruses | Any of the viruses that cause inflammation of the liver. They include both DNA and RNA viruses as well viruses from humans and animals. (12 Dec 1998) |
| serum hepatitis | <virology> A form of viral hepatitis, known as serum hepatitis, because it is commonly spread through contact with infected blood products (transfusion). May also be spread sexually or from mother to infant. Hepatitis B can cause a much more severe infection than hepatitis A and can occur as an asymptomatic carrier state, a chronic infection or as cirrhosis of the liver. Those at risk (IV drug abusers, health care workers, dialysis patients, transfusion recipients, homosexuals) should be immunised with hepatitis B vaccine. The virus is 42nm diameter, with an outer sheath enclosing inner 27nm core particle containing the circular viral DNA. Aggregates of the envelope proteins are found in plasma and are referred to as hepatitis B surface antigen (HBsAg, previously called Australia antigen). The virus can persist for long periods (and in asymptomatic carriers), association of integrated virus with hepatocellular carcinoma is now well established. (27 Sep 1997) |
| short incubation hepatitis | A virus disease with a short incubation period (usually 15 to 50 days), caused by hepatitis A virus, a member of the family Picornaviridae, often transmitted by faecal-oral route; may be inapparent, mild, severe, or occasionally fatal and occurs sporadically or in epidemics, commonly in school-age children and young adults; necrosis of periportal liver cells with lymphocytic and plasma cell infiltration is characteristic and jaundice is a common symptom. Synonym: epidemic hepatitis, hepatitis A, infectious hepatitis, MS-1 hepatitis, short incubation hepatitis, virus A hepatitis. (05 Mar 2000) |
| NANB hepatitis | Hepatitis caused by two or more infectious agents not detectable by methods that reveal the presence of hepatitis viruses A and B; one cause, now called type C hepatitis has been identified; may follow blood transfusion and is often seen in chronic renal dialysis patients. Synonym: NANB hepatitis. (05 Mar 2000) |
| neonatal hepatitis | Hepatitis in the neonatal period presumed to be due to a variety of causes, chiefly viral; characterised by direct and indirect bilirubinaemia, hepatocellular degeneration, and appearance of multinucleated giant cells; may be difficult to distinguish from biliary atresia, but is more likely to end with recovery, although cirrhosis may develop. Synonym: giant cell hepatitis. (05 Mar 2000) |
| subacute hepatitis | <pathology> This is a form of continuing liver inflammation that results in liver cell death. Causes include viral infection (hepatitis D, hepatitis B, hepatitis C), autoimmune disease, drug ingestion or metabolic causes. Chronic active hepatitis will lead to hepatic failure and death in a small percentage of these patients. (27 Sep 1997) |
| non-A, non-B hepatitis | Hepatitis caused by two or more infectious agents not detectable by methods that reveal the presence of hepatitis viruses A and B; one cause, now called type C hepatitis has been identified; may follow blood transfusion and is often seen in chronic renal dialysis patients. Synonym: NANB hepatitis. (05 Mar 2000) |
