1
Q

In VHL, whats more common, renal cell carcinoma or pheochromocytoma?

A

renal carcinoma is much more common.

2
Q

macrocytic anemia in alcoholic.

A

if it doesnt say megaloblastic, could just be a macrocytic anemia from the toxic damage alcohol has on the bone marrow.
-so dont disregard a thiamine deficiency just because you see alcoholic w/macrocytic anemia.

3
Q

Would you ever use lumbar puncture on a pt w/inc. ICP?

A

No, never.

-could lead to herniation.

4
Q

MCA stroke

-Sxs:

A
  • language deficit or hemineglect.

- contra motor/sensory deficit in face/upper limbs.

5
Q

ACA stroke

-Sxs:

A

-contra motor/sensory deficit in lower limb.

6
Q

ASA stroke

-Sxs:

A

anterior spinal artery

  • contra hemiparesis upper & lower limbs.
  • dec. contra proprioception (DC/ML).
  • Ipsilateral hypoglossal dysfunction (tongue deviates ipsilaterally).
7
Q

ASA stroke

-Sxs:

A

anterior spinal artery

  • contra hemiparesis upper & lower limbs.
  • dec. contra proprioception (DC/ML).
  • ipsilateral hypoglossal dysfunction (tongue deviates ipsilaterally).
8
Q

PICA stroke

-Sxs:

A

dec. pain and temperature sensation from ipsilateral face and contralateral body.

9
Q

PICA stroke

  • what tissue is affected?
  • Sxs:
A
  • lateral medulla.

- dec. pain and temperature sensation from ipsilateral face and contralateral body.

10
Q

ASA stroke

-Sxs:

A

anterior spinal artery

  • contra hemiparesis upper & lower limbs.
  • dec. contra proprioception (DC/ML).
  • ipsilateral hypoglossal dysfunction (tongue deviates ipsilaterally).

*caudal medulla = hypoglossal n.

11
Q

PICA stroke

  • what tissue is affected?
  • Sxs:
A
  • lateral medulla.
  • dec. pain and temperature sensation from ipsilateral face and contralateral body.
  • dysphagia, hoarseness.
  • ipsi Horners.
  • Vomiting, vertigo, nystagmus.
12
Q

Lateral medullary (Wallenberg) syndrome.

  • wheres the stroke? which art & what region?
  • Sxs:
  • mnemonic:
A
  • Nucleus ambiguus effects are specific to PICA lesions.
  • “Don’t pick a (PICA) horse (hoarseness) that can’t eat
    (dysphagia) .”
13
Q

nucleus ambiguus

-function?

A

Motor innervation of pharynx, larynx, and upper esophagus (e.g., swallowing, palate elevation).
-its a vagal nuclei.

14
Q

Lateral medullary (Wallenberg) syndrome.

  • wheres the stroke? which art & what region?
  • Sxs:
  • mnemonic:
A
  • Nucleus ambiguus effects are specific to PICA lesions.
  • “Don’t pick a (PICA) horse (hoarseness) that can’t eat
    (dysphagia) .”
15
Q

Which affects are specific to PICA lesion?

A
  • Nucleus ambiguus effects are specific to PICA lesions.
  • “Don’t pick a (PICA) horse (hoarseness) that can’t eat
    (dysphagia) .”
16
Q

Which affects are specific to PICA lesions?

A
  • Nucleus ambiguus effects are specific to PICA lesions.
  • “Don’t pick a (PICA) horse (hoarseness) that can’t eat
    (dysphagia) .”
17
Q

Which affects are specific to AICA lesions?

A

Facial nucleus effects are specific to AICA lesions.

“Facial droop means AICA’s pooped.”

18
Q

Which affects are specific to AICA lesions?

A

Facial nucleus effects are specific to AICA lesions.
“Facial droop means AICA’s pooped.”

*dont confuse w/loss of pain/temp from face like you can see in others. This is loss of motor function of facial nerve so you get dropping.

19
Q

PICA stroke

-what tissue is affected?

A

-lateral medulla.

20
Q

AICA stroke

-what tissue affected?

A

lateral pons.

21
Q

Basilar artery stroke

-Sxs:

A

“Locked-in syndrome.”

-pontine branches come from basilar art.

22
Q

Basilar artery stroke

-Sxs:

A

“Locked-in syndrome.”

  • pontine branches come from basilar art.
  • same Sxs as Central pontine myelinolysis.
23
Q

ACom stroke

-Sxs:

A

visual defects.

24
Q

PCom stroke

-Sxs:

A

CN 3 palsy.
