Q

For prophylaxis VTE treatment pre-surgery, when is dabigatran used?

A

Used prohylactically in hip and knee surgery. It does not require therapeutic monitoring. It has no known antidote and should not be used in any patient in whom there is a risk of active bleeding

Q

What is the management for a patient who has been treated for acute pancreatitis, found to have a cystic lesion on the head of the pancreas, but is clinically stable?

A

Conservative management - it is a pancreatic pseudocyst. A raised amylase and a cystic lesion following pancreatitis is most likely to represent a pseudocyst. If a procedure would be required, then a radiological fine needle aspiration would be best suited.

Q

Why does a third cranial nerve palsy occur with some head injuries?

A

If the head injury results in an uncal herniation - the uncus of the temporal lobe herniates under the free edge of the tentorium cerebelli. The herniated uncus compresses the third cranial nerve causing a surgical third nerve palsy, presenting as a dilated and unreactive pupil
