20
Q

Miller fisher variant of GBS?

A

oculoparesis, ptosis, ataxia, areflexia

21
Q

tx of GBS?

A

IVIG or pharesis

22
Q

ticke borne paralysis sx?

A

tick needs to fed for 7 days first, also ascending paralysis

23
Q

MG sx? diagnosis?

A

ach receptor ab, proximal muscle weakness

24
Q

anti NMDA encephalitis association?

A

ovarian and testicular teratoma

25
Q

presentation of anti NMDA encephalitis?

A

young patient with paranoia or psychosis who deescalates to encephalopathy and seziures

26
Q

ascending paralysis complicated by areflexia and proprioception loss?

A

AIDP

27
Q

tx for AIDP?

A

plasmapharesis or IVIG

28
Q

tx for GBS?

A

IVIG or pharesis

29
Q

complications of IVIG?

A

anaphylaxis, aseptic meningitis, renal failure, fluid overload

30
Q

central cord syndrome cause? sx?

A

likely in setting of arthritis in older patients, loss of motor and sensory in arms and legs

31
Q

reversal of nondeploarizing NMB like cisatracurium?

A

neostigmine

32
Q

combat muscarinic effects of neostigmine?

A

glycopyrolate

33
Q

how does suggamadex work?

A

encapsulates NMBA in plasma and then creates a concentration gradiest to pull more out of muslce and eliminated via kidneys

34
Q

nutritional deficiency that can mimic GBS?

A

thiamine deficiecny- beriberi

35
Q

wernicke encephalopathy presentation?

A

vomiting, horizontal nystagmus, palsies of eye movement, fever, ataxia

36
Q

MIP and NIF threshold for MG?

A

> -20 NIF is bad, <40 on MIP bad, VC <15 cc/kg

37
Q

poor indicator for VC on MG assessment?

A

<20 cc/kg

38

improvement in ocular movement and proptosis, assessing for MG

39
Q

concern for excess pyridostigmine when treating MG?

A

cholinergic crisis

40
Q

treatment for MG

A

IVIG or pharesis for 5 days

41
Q

weakness with progressive decrement of action potentials with repetitive motion on electrophysiological studies?

A

MG

42
Q

weakness that will show electrophysiological with acute inflammatory demyelinating polyneuropathy

A

GBS

43
Q

cholingergic crisis in which of the weaknesses?

A

MG

44
Q

sx of cholingergic crisis in MG?

A

urinary retention, bradycardia, inc oral secretions, SLUDGE

45
Q

tx of cholingergic crisis in MG?

A

Supportive use atropine

46
Q

syringobulbia?

A

cysts in brainstem with gradual onset of motor, sensory, and autonomic sx

47
Q

when is it ok to use BIPAP in myasthenia crisis?

A

before the patient develops hypercapnia
