Q

Pt presents with hepatic encephalopathy, bleeds readily and is jaundiced. They’re nauseous and tired. You notice ascites.

Likely diagnosis? Tx?

A

Liver Failure
(Acute <26wks. Chronic if Hx cirrhosis)

Lactulose + Mannitol

VitK + Plasma

22
Q

Management of Alcoholic Liver Disease.

Management of withdrawals

A

Abstinence + Oxazepam

Withdrawals: Chlordiazepoxide, Acamprostate, Naltrexone

23
Q

Management of Non-Alcoholic Liver Disease

A

VitE + Orlistat + Insulin-sensitizer

Lifestyle

24
Q

How do we assess the severity of someone’s alcoholism?

A

AUDIT + SADQ Questionnaire

25
Q

Pt presents with dark urine, jaundice and pale stools. Their ALP is markedly raised.

Likely diagnosis

A

Gallstones - obstructive cause of jaundice

ALP is upregulated in response to cholestasis

26
Q

Isolated raised ALP indicates…

Where is ALP concentrated?

A

Isolated raised ALP indicates Bone pathology: tumour, vitD deficiency, fracture

ALP is concentrated in:

  • liver
  • BILE DUCT
  • Bone tissue

ALP is upregulated in response to cholestasis :, is a good marker

27
Q

Where is ALT concentrated?

A

ALT is concentrated in HEPATOCYTES :. is a good marker for hepatocellular injury:
- hepatitis

28
Q

A marked raise in ALT and mild raise in ALP indicates…

A

Hepatocellular injury, eg Hepatitis

= Hepatic jaundice

29
Q

A marked raise in ALP and mild raise in ALT indicates…

A

Cholelithiasis

= Post-hepatic jaundice

30
Q

Pt is jaundiced, however their ALT and ALP levels are normal.

Likely cause? What will their urine and stools look like?

A

= Pre-hepatic cause of jaundice

  • GILBERT’s SYNDROME (impaired conjugation of bilirubin)
  • HAEMOLYTIC ANAEMIA (haemolysis = more bilirubin)

Unconjugated Bilirubin is water insoluble, so:
- Normal urine colour

Pre-hepatic pathology, so fat absorption unaffected:
- Normal stool colour

31
Q

What is Prothrombin Time?

Primary causes of raised PTT?

Secondary causes of raised PTT?

A

PTT = measure of blood’s coagulation tendency

Primary causes = Liver disease/ dysfunction

Secondary causes = anticoagulants + Vitamin K deficiency

32
Q

Low AST/ALT ratio indicates…

ie ALT >AST

A

Chronic liver disease

33
Q

High AST/ALT ratio indicates…

ie AST > ALT

A

Cirrhosis, acute alcoholic hepatitis, alcohol abuse

34
Q

Most common cause of hepatitis in travellers

Presentations?

A

Hepatitis A Virus

  • faecal-oral route
  • Abrupt onset
  • fever, n/v
  • JAUNDICE 2wks post-infection
35
Q

Acute vs Chronic Hepatitis

A

Acute <6 months

Chronic >6 months

36
Q

48-M presents to GP with a swollen groin; he has noticed increasing pain the last few days. examination reveals a lump superior and medial to the pubic tubercle on the left. The lump is partially irreducible.

There is no erythema; cough impulse is present.

Likely diagnosis? RF?
Management?

A

Inguinal hernia (cannot get above it - irreducible/ partially irreducible)

RF:

  • Old M
  • connective tissue disease
  • AAA
  • prematurity

Management:
Symptomatic + irreducible: urgent referral to secondary care

(because increased risk of strangulation)

37
Q

HBsAg indicates…

A

Surface antigen - Acute HBV

38
Q

HBeAg indicates…

A

E antigen - HBV Viral replication, implies high infectivity

39
Q

HBcAb indicates,,,

A

Core antibody - Past/ current HBV Infection

40
Q

HBsAb indicates…

A

Surface antibody - HBV vaccination/ past/ current infection

Vaccines inject surface antigens :. surface Ab develop

41
Q

Pt has malaise, joint pain and jaundice for 2 months. Hepatitis screen shows: HBsAg, HBeAg, HBcAb.

Likely diagnosis?

A

ACUTE (<6 months)

surface Ag - high infectivity
core Ab - current/ past
e antigen - current

= Acute HBV Infection

42
Q

Abdominal distension, shifting dullness, fluid thrill

A

Ascites

43
Q

Causes of ascites

A

Meig’s syndrome classic triad

A
  • Benign ovarian tumour
  • ascites
  • pleural effusion
