MSRA Miscellaneous Flashcards
how is Wells score interpreted for DVT?
2 or more = DVT likely, do proximal leg USS
1 or less = DVT unlikely, do D-dimer within 4 hours (if result not available in this time, start interim anticoagulation)
how is Wells score interpreted for PE?
More than 4 = PE likely, do CTPA
4 or less = PE unlikely, do D-dimer
what is the difference between wernicke’s and broca’s aphasia?
1) wernicke’s (receptive)
- lesion of superior temporal gyrus which usually forms speech before sending it to broca’s
- results in word salad with impaired comprehension
2) broca’s (expressive)
- lesion of inferior frontal gyrus
- non-fluent, laboured speech with normal comprehension
what is conduction aphasia?
typically due to stroke affecting arcuate fasiculus (connection between wernicke’s and broca’s area)
speech fluent but repetition poor, pt aware of errors they are making, normal comprehension
