liver failure
drugs

19
Q

what is the differnece betwen predicatibs and unpredicel drug induced symptsons

A

unpredictable - any dose can cause an adverse reaction
predictable - more likely to happen in higher doesse

20
Q

what is intrahepatic bile duct obstrucrtion cuases

A

tumours of the liver
priamry sclerosing cholangistis
primar biliary cholangitis

21
Q

what are example of tumours of the liver

A

hepatocellurla carcinoma
turmours within intrahepatic bile ducts
metatisc tumours

22
Q

what is primary biliary cholangitis

A

an organ spefic granulomatus inflatoin involving the bile ducts
it is autoimmune
cuase loss of intrahepatic bile ducts and causes cirrhosis

A

mitochonial antibodies

26
Q

how is mianly effected by sclerosing cholangitis

A

young men with ibf

27
Q

what is damaged as a result of primary sclerosing cholagits

A

chromic inflation and firbous obliter of bile ducts
loss of intra hepatic bile ducts

Q

disting feature betwene sclerosing and bilary

A

no grnamuos tissue in sclerosing i

29
Q

what happen sin long tern primary sclerosing cholangitis

A

prgoressive to cirrhosis
incresing the risk of development of cholangiocarnioa

30
Q

what are the causes of cirrhosis

A

alchol
hep b, c
immune mediated liver diease, auto immune hepatis

complicaitons of cirrhosis

A

altered liver function
abnomral blood flow - protal hyperteion
incraed risk of hepatocleluar coarcinoma
