Q

What is the screening tool for harmful alcohol use and what are the questions?

A

CAGE questionaire

C- have you ever thought about cutting down?
A- do you get annoyed when other people comment on your drinking?
G- do you ever feel guilty about your drinking?
E- eye-opener. Ever drink in the morning to help with your hangover/ nerves

AUDIT questionnaire is a better way of screening but is longer

Q

What do blood tests show in alcohol abuse?

A

Q

What is the pathophysiology of alpha-1-antitrypsin deficiency?

A

Elastase is an enzyme which is secreted by neutrophils and this enzyme digests connective tissues. Alpha-1-antitrypsin is mainly produced in the liver and it inhibits the neutrophil elastase enzyme. Without this there is liver cirrhosis, bronchiectasis and emphysema

A

Eating worsens the pain of gastric ulcers and improves the pain of duodenal ulcers

86
Q

What is the management of peptic ulcers?

A

High dose PPI

87
Q

How are peptic ulcers diagnosed?

A

Maintain remission through azathiopurine or mercaptopurine

99
Q

What is the management of UC?

A

Induce remission:
1st amiosalicylate such as mesalazine
2nd steroids
