MIKN Methyldopa Isoniazid Ketoconazole Nitrofurantoin
Hepatitis types that cause chronic hepatitis?
Hep B, Hep C, Hep D
What is fulminant hepatic failure?
Severe hepatic failure in which encephalopathy develops in under 2 weeks in a patient with a previously normal liver
Histologically there is multiacinar necrosis involving a substantial part of the liver

Thyrotoxicosis
Coeliac disease
Treatment for autoimmune hepatitis?
Steroid and aziathioprine therapy
Management of NAFLD?
Weight loss, exercise, strict control of hypertension, diabetes and lipid levels
Characteristic features of cirrhosis?
Regenerating nodules separated by fibrous septa and loss of the normal lobular architecture within the nodules
Micronodular cirrhosis?
Regenerating nodules <3mm
Macrondoular cirrhosis?
This type is often seen following chronic viral hepatitis (I reckon nodules are >3mm)
Best indicators of liver function?
Serum albumin and prothrombin time
Liver biochemistry in cirrhosis?
This can be normal, depending on the severity of the cirrhosis
In most cases, there is at least a slight elevation in the serum ALP and serum aminotransferase
In decompensated cirrhosis, all biochemistry is derranged
Increased echogenicity of the liver on US?
Fatty change and fibrosis
Percentage of patients with cirrhosis that will develop gasto-oesophageal varices?
90%
But only one third will bleed from them
Treatment for variceal bleeding?
Variceal banding or injection scleropathy
(terlipressin, somatostatin)
(Balloon tamponade)
-Re-bleeding occurs in about 15-20% within 5 days after a single session of therapeutic endoscopy
Fluid within the peritoneal cavity?
Ascites
Neutrophil count in bacterial peritonitis?
Neutrophil count above 250 cells/mm is INDICITAVE OF AN UNDERLYING (usually spontaneous) BACTERIAL PERITONITIS
