General Flashcards
What are two clinical signs of meningism?
Kernig’s sign (knee flexion + extension elicits pain) + Brudzinski sign (passive flexion of neck illicits flexion of knee). Both are signs of meningism. Observed in SAH
New acute back pain + bilateral weakness + cancer.
a. osteomalacia
b. prolapsed disc
c. spinal cord compression
d. vertebral fracture
spinal cord compression
Which drug should be used for the secondary prevention of stroke in a patient with AF?
DOAC e.g. apixaban
Which drug is first line in the secondary prevention of stroke?
clopidogrel
Which spinal tract mediates fine touch, vibration, and proprioception?
dorsal column
Which spinal tract mediates pain and temp?
lateral spinothalamic tract
Which is the motor tract of the spinal cord?
lateral corticospinal tract
Which nerves are parasympathetic?
Cranial 3, 7, 9, 10
S2-S4
Which nerves are sympathetic?
T1-L2 cell bodies
List three signs of UMN lesion
Hyperreflexia Up-going plantars/positive babinski spasticity: tone +- clonus pyramidal weakness: extensors in UL and flexors in LL no wasting
List three signs of LMN lesion
wasting fasiculation flaccidity: reduced tone hyporeflexia down-going plantars
What is the pattern of Brown-Sequard syndrome?
ipsilateral loss of proprioception/vibration and motor weakness with contralateral loss of pain
Which spinal tract mediates crude touch?
anterior spinothalamic tract
What are the two divisions of the dorsal columns?
fasciculus gracilis- lower trunk and legs
fasciculus cuneatus- upper trunk and limbs
Differentials for brown sequard syndrome?
penetrating trauma to neck or back
ischaemia
infectious of inflammatory process e.g. MS, TB
