unknown, superoxide dismutase?

172
Q

ALS pt

A

both UMN lesion and LMN lesions
upper = hyperreflexia, positive babinski
lower = atrophy, fasciculation

173
Q

ALS dx

A

r/o spinal lesions = XR/CT/MRI

best = EMG

174
Q

ALS tx

A

none

‘riluzole’ (if you see this word, it’s ALS)

175
Q

MS path

A

autoimmune

demyelinating

176
Q

MS pt

A

neuro symptoms separated in both time and space

optic neuritis = blurry vision (painful)

177
Q

MS dx

A

1st and best = MRI with periventricular white lesions, demyelinating plaques

178
Q

MS tx

A

acute: methylprednisolone x5d
chronic: IFN + glatiramer, fingolimod
symptom control
- urinary retention = bethanechol
- urinary incontinence = amitryptiline
- spasms = baclofen
- neuropathic = gabapentin

179
Q

myasthenia gravis path

A

autoimmune

antibodies against ACh-R

180
Q

myasthenia pt

A

fatiguability of small muscles

blurry vision, dysphagia worse at end of day

181
Q

myasthenia dx

A

1st: antibodies
best: EMG
then: CT chest = thymic mass

182
Q

myasthenia tx

A

increase ACh with stigmine (neostigmine)
decrease autoimmune
- steroids >60, thymectomy < 60
- IVIG = plasmapheresis in acute crisis

183
Q

myasthenia f/u

A

edrophonium not used anymore

184
Q

Guillain-barre path

A

autoimmune

demyelinating

185
Q

Guillain-barre pt

A

ascending paralysis following diarrhea or vaccination

hyporeflexia, diaphragmatic paralysis

186
Q

Guillain-barre dx

A

1st: do they need intubation? … PFTs
then: LP = lots of protein, few cells
best: nerve conduction

187
Q

guillain-barre tx

A

IVIG = plasmapheresis

NEVER steroids
