OSCE Revision Flashcards
(370 cards)
anterior cerebral artery blockage will lead to weakness of
lower limb contralaterally
vascular dementia presentation
step wise progression
onset can be sudden or gradual
executive function deficits prominent early
mood disturbances and disorders are common
neuro deficits and gait problems early
later stages = psychosis, delusions, hallucinations, paranoia
can be alongside alzheimers
AIDP
acute inflammatory demyelinating polyneuropathy
most common variant of GBS - 95% cases
Weakly positive birefringent, rhomboid shaped crystals
Calcium pyrophosphate = pseudogout
how to measure lying and standing BP
patient lay down for 5/10 minutes
take BP
then stand and take BP at 1 min and 3 min
DVLA and stroke /TIA
group 1 - dont need to report. dont drive for 1 month and can drive if no sustained neuro deficits after 1 month
group 2 = 1 year cant drive
risk factors for vascular dementia
main = HTN
smoking, diabetes, hyperlipidaemia, obesity, hypercholesterolaemia
retinal detachment presentation
new onset floaters, photopsia (bright flashes), sudden onset progressing visual field loss - a dark shadow that moves inwards
RAPD if macula or >1/2 retina detaches
Smith’s fracture
Volar displacement of radius head
treatment of parkinsons disease
1) levodopa + dopa decarboxylase inhibitor
2) dopamine agonist
3) MAO-B inhibitor
presentation of bacterial conjunctivitis
mucopurulent secretions, red eye, stinging, FB feeling, mild/moderate pain, glued eyes upon waking, papillae under eye lid
Z shaped thumb
Sign of RA-MCPJ flexion and IPJ extension
Negatively birefringent, needle shape crystals
Monosodium urate = gout
co beneldopa
levodopa and Benserazide
features of vascular parkinsonism
gradual or step wise deterioration small vessel disease symmetrical predominantly leg symptoms 50% respond to leva dopa
prophylactic treatment for migraine
if > 2 headaches a month
propranolol, topiromate, amitriptyline
2nd line - sodium valproate, botox
Ankle joint bones
Tibia, fibula and talus
Radial inclination
Normal wrist has 25 degrees radial inclination
presentation of parkinsons disease
resting tremor rigidity bradykinesia - reduced arm swing, progressive reduction in amplitude of repetitive movements fixed facial expression reduced blinking hypophonia (quiet voice) micrographia (little writing) gait disturbance hyposmia non motor symptoms - ANS: orthostatic hypotension, constipation, inconinence, sleep disorders, intense dreams, dysphagia, memory/ concentration problems.
prophylaxis of further aacg attacks
laser peripheral iridotomy
amiodarone
used for cardioversions in atrial fibrillation
donepezil
cholinesterase inhibitor for dementia
delirium
acute onset, fluctuating confusion due to an underlying treatable cause
investigations for encephalitis
LP - PCR for HSV, VZV and enterovirus
MRI and bloods
