Flashcards in Holgar Videos (Druggy Dogs) Deck (12):
What is clonus?
- shivering or flex/extension prolonged in response to a single stimulus
Which breeds are commonly affected by vascular lesions?
What is high velocity/low volume disk extrusion?
- acute nucleus pulposus extrusion (cant actually tell the velocity)
- bit of healthy disk breaks off and shoots into SC
- initially painful, improvies within 24hours
Why does the cauda equina exist? Where does it begin?
- SC and vertebral column grow at different rates (L1 in humans, L??? in dogs, further back in small breeds)
What is Shiff-Sherrington? Is this a prognostic indicator?
- ^ tone htoracic limbs
- no tone pelvic limbs
- d/t border cels thoracolumbar region affected
- NOT a prognostic indicator, but worse Shiff-Sherrington indicates deeper structures affected so likely vascular event (affecting middle of SC) cf. cord compression d/t IVDD etc.
Tx vascular lesions?
- optimise perfusion (fluids)
- cage rest
Ddx for shiff-sherrington type presentation?
- r/o as proprioception of forelimbs still present with Shiff
How may UMN lesions present?
- acute: flaccid "spinal shock" T3-L3 myelopathy looks like LMN, peracute lesion with NO reflexes - will resolve spontaneously ~24hrs
- chronic: spastic
What pathology are border terriers predisposed to?
> canine epileptoid cramping disorder
- episodic, paroxysmal, normal conciousness but all 4 limbs affected (~= generlsied seizure)
- GI problems also seen - gassy
What is labrador myopathy?
congenital centronuclear myopathy
What pathology are bulldogs predisposed to?
> idiopathic head tremors
- "yes" or "no" shaking
- 60% will grow out of the conditions
