erythema nodosum vs erythema multiforme?

A

Erythema multiforme is typically target shaped and only slightly raised. It’s not typically painful but can be itchy. They can also be on various sites of the body

Erythema nodosum is more like a raised nodule that mainly presents on the shins. It looks a bit like a bruise and it is painful.

Q

What clotting factors and other components does the liver make?

A

2) Albumin (transport and maintain BP)

3) Transport proteins= ceruloplasmin (transports copper) and transferrin (iron)

4) Bile salts (fat digestion)

5) Bilirubin (from RBC breakdown)

6) Glucose (through gluconeogenesis and glycogen storage/release)

7) Lipids (cholesterol, trigly and lipoproteins)

Budd-Chiari Ix- way to remember?

(pt presents with abdo pain, tender hepatomegaly and ascites- basically a painful swollen liver)

A

USS with doppler.

basically a ‘liver DVT’ , being a hepatic vein thrombosis.
The ‘painful, swollen calf’ is essentially just a painful swollen liver (abdo pain, tender hepatomegaly) + ascites due to venous obstruction.

They also have exactly the same gold standard investigation in Doppler Ultrasound!

Q

ALP, AST and ALT produced by what?

A

AST & ALT produced by hepatocytes; in hepatocellular disease, hepatocytes release these enzymes into blood so get raised ALT.

ALP produced by cells lining bile duct so in obstructive disease ALP rises.

Q

When to measure troponin?

A
  • Depends on assay
    STH assay – hsTnT:
  • Measure ASAP
  • If raised, measure again in 3h – significant rise or fall suggests MI
  • If not raised, can r/o MI, unless pain was <6 hrs ago, in which case obtain further measurement at that point – significant rise suggests MI
  • Does NOT rule out ACS (could still be unstable angina)
  • MI is NOT always due to ACS

MI- what to write on the TTO?

2) Potent P2Y12 inhibitor – ticagrelor 90 mg BD or prasugrel 5-10 mg OD for >=1 year. Can consider a PPI alongside.

3) Cardioselective beta blocker (caution if asthmatic, bradycardic, conduction disease) e.g. bisoprolol 2.5 mg OD

4) ACE inhibitor (ARB if intolerant due to cough) (caution if hypotensive, severe CKD) e.g. ramipril 2.5 mg OD

5) High intensity statin e.g. Atorvastatin 80 mg OD

(PRN GTN)

Pretty much most pts will go home on these if tolerated

    Loop diuretic e.g. Furosemide 40 mg OD
    SGLT2 inhibitor e.g. Dapagliflozin or Empagliflozin

AF causing TIA - Mx

A

normal stroke - aspirin first, then lifelong clopi
normal TIA - aspirin first, then lifelong clopi
AF causing stroke - aspirin first, then DOAC
AF causing TIA - immediate DOAC

A

48 hours of presentation

276
Q

A patient develops acute heart failure 5 days after a myocardial infarction. A new pan-systolic murmur is noted on examination -

A

ventricular septal defect

277
Q

Mx of aortic dissection?

A

ST depression not elevation

283

PR interval over 200ms with an otherwise normal ECG (regular sinus rhythm, no missing QRS complexes) is consistent with

A

1st-degree atrioventricular block.

Isolated 1st degree atrioventricular block is common rarely problematic and a normal variant in athletes
