A 74-year-old man is suspected with per rectal bleeding. Per rectal examination shows negative result with normal mucus and stool. You then proceed for faecal occult blood test.

A. Liver metastasis

Small chronic peptic ulcer, no gallstones, several calcified spots are found in pancreas. Which of the followings is the most likely pathological finding?
A. Acute haemorrhage, necrosis of pancreas
B. Infiltrative CA in pancreas
C. Superficial gastric erosion
D. Islet cell hyperplasia

60 years old male, dyspnoea, frothy sputum. Physical examination shows rales (Creptiation) in all lung field. Echocardiogram shows ejection fraction 30%, concentric left ventricular hypertrophy, heart valves are normal. What is the most likely cause?
A. Myocarditis
B. Pericarditis
C. Hypertension
D. Amyloidosis
E. Cardiomyopathy
C
What is the mechanism of H. pylori-associated gastritis?
H. Pylori is well adapted to the stomach:
● Secretes urease → break down urea and raise pH
● Flagella → to swim in thick mucus
● Adhesins → adheres to surface of gastric mucosa
● Produces toxin
Colonisation of H. Pylori in the stomach → infection and inflammation in stomach → gastritis
the indication for liver biopsy
inconclusive imaging results
How to differentiate HCC and colonic metastasis under microscope?
by background of cirrhosis
by architecture (hepatocellular differentiation with thickened trabeculae v.s. glandular differentiation)
by IHC (HBsAg v.s. mucin)
