Ischemic or Autoimmune hepatitis
Wilson disease
Acute bile duct obstruction
Acute Budd Chiari syndrome
Hepatic a. ligation
EUS - endoscopic ultrasonography - ANSWER most sensitive test for

aversion to smoking
Fever, enlarged and tender liver, jaundice
Norm to low WBC, markedly elevated aminotransferases early in the course
Liver bx - hepatocellular necrosis and monomuclear infiltrate, but is rarely
indicated.
Hep B transmission - ANSWER blood or blood products
sexual -saliva, semen and vaginal secretions.
HBsAg pos mothers may transmit at delivery - high risk of chronic infection
