  1. Which drugs can cause a raised troponin I?
    • Adriamycin,
    • Herceptin and
    • 5-fluorouracil
  2. How do you differentiate between NMS and Serotonin syndrome?
    Hz and Ex mainly.

    • NMS develops over days to weeks, whereas serotonin syndrome develops over 24 hours.
    • Serotonin syndrome is characterized by neuromuscular hyperreactivity (tremor, hyperreflexia, myoclonus),
    • while NMS involves sluggish neuromuscular responses (rigidity, bradyreflexia). Hyperreflexia and myoclonus are rare in NMS.

    Also, resolution of NMS typically requires an average of nine days, compared with less than 24 hours (usually) for resolution of serotonin syndrome
  3. Whats the best investigation to monitor infections of the aortic valve/root?
    Daily ECGs to look for PR prolongation which happens due to disruption of the AV node

  26. What does an unrecordable thyroglobulin indicate?
    • The patient is taking thyroid meds.
    • Thyroglobulin is the precursor to thyroid hormone and therefore if unrecordable with elevated thyroid hormones, they are taking thyroid meds.
  27. What antimicrobial prophylaxis would you give to a patient about to have chemo with a purine analogue?
    • Septrin for PCP.
    • You can stop it once their CD4 is >200

    • TLCO is the amount of CO you are transferring across the entire long
    • KCO is the amount of CO you are transferring across a smaller unit volume.
    • Whatever increases the amount of red blood cells coming into contact with alveoli will increase your Kco.

    • Both should go up and down together.
    • If they dont - you have a Extrapulmonary restriction. (Widespread pleural disease, thoracic cage deformities and resp muscle weakness)
