Q

What in a pt’s hx for would be red flag symptoms for a HA?

A

less than 5 and older than 50 with NEW and WORSENING HA

sudden onset: cerebral aneurysm rupture

sudden onset with exertion: subarachnoid hemorrhage

different quality of pain when compared to their usual HA symptoms

fever onset in relation to HA onset

on anticoag/antiplatelet: increased risk of hemorrhage

recent abx use because it can result in less severe clinical presentation

What is the tx for a tension HA? What is an important pt education point?
NSAIDs +/- caffeine +/- antiemetic/sedative ketorolac + Compazine/Reglan + diphenhydramine IV for acute relief in ED muscle relaxant but can be sedating to advise to take at night pt education: take medication as soon as you feel symptoms come on, DON'T WAIT to take meds!!
31
**What is an important question to ask that will help differentiate between a brain tumor and a different cause of a HA?
Worse upon awakening and with valsalva
32
What will a brain tumor feel like early in the disease process? What is likely to occur as time passes?
mild/moderate deep aching pain that can be bilateral or unilateral no focal neurological signs are present **HA increase in frequency and duration over weeks-months (classic history)**
33
What will a brain tumor feel like later on in the disease process?
constant pain focal neurologic s/s will develop n/v, seizures, mental status changes
34
Why is there constant pain present later on in the course of the dz process?
due to CSF flow obstruction occurs or intracranial hypertension develops
35
What dx test should you order if you suspect a brain tumor? What is the management?
CT scan WITH CONTRAST management: emergent! neuro/neurosx eval IV dexamethasone IV secondary prevention of antiseizure meds - levetiracetam (Keppra), topiramate (Topamax), lamotrigine (Lamictal), valproic acid, and lacosamide (Vimpat) secure an airway!! if s/s of herniation on
36
What is the timing associated with Post Concussive Syndrome? What will the HA feel like? When should you perform imaging?
pain can be immediate after trauma or onset may be weeks after trauma non-specific can be similar to tension/migraine presentation imaging is only needed if they did NOT have imaging on their previous evaluation
37
What is the management for Post Concussive Syndrome? When do most pts typically improve?
nothing! Uncomplicated cases can be discharged home with simple reassurance, symptomatic therapy and f/u with PCP improve within 3 months
38
If medication is needed for Post Concussive Syndrome, what are your 2 best options?
Non-opiate pain relievers and antiemetics
39
**What are 3 vital pt education points for Post-traumatic Headache/Syndrome?
avoid activity that could lead to second injury while symptomatic (aka no sports, yard work etc etc) avoid activity that exacerbates symptoms gradual return to normal activity once symptoms resolve
40
What are the 3 findings consistent with Idiopathic Intracranial Hypertension? What is usually present on PE?
papilledema, increased ICP (with normal CSF), and normal/small-sized ventricles on imaging papilledema, visual field loss, 6th CN (abducens) palsy (loss of lateral gaze) other CN may be affected but much less commonly
41
What are transient visual obscurations? What dz are they associated with?
blackening or graying out of vision with activity that increases ICP idiopathic intracranial hypertension
42
What are scotoma? Scintillations? What dz are they associated with?
scotoma: black spot in visual field scintillations: flickering lights in visual field Idiopathic Intracranial Hypertension
43
What is retrobulbar pain? what are 2 risk factors for Idiopathic Intracranial Hypertension?
pain behind the eye female and obesity
44
What are the two diagnostic evaluations that should be ordered in Idiopathic Intracranial Hypertension?
brain CT without contrast: will be NORMAL LP: opening pressure will be elevated greater than 25cm in adults and greater than 28 in kids
45
What will the opening pressure be in Idiopathic Intracranial Hypertension for an adult? kid? What will the CSF fluid analysis show? What position should you place the pt in?
elevated opening pressure¹ > 25 cm H2O in adults and > 28 cmH2O in children CSF fluid is NORMAL left lateral decubitus
46
What is the management for Idiopathic Intracranial Hypertension? What is the primary focus of tx?
remove CSF fluid until target pressure of 10-20 cm H2O is reached if visual symptoms present: oral acetazolamide +/- thiazide diuretic neurologist/neurosx referral focus is to preserve vision!!
47
What is the target opening pressure when treating a pt with Idiopathic Intracranial Hypertension? Why are you giving acetazolamide?
Removal of CSF during LP until target pressure of 10-20 cm trying to reduce the rate of CSF production
48
What is the typically presentation of Post-Dural Puncture/Intracranial Hypotension? **What position is the HA worse in?
recent hx of LP within 24-48 hours HA worse in upright position, improves in supine position
49
What do you need to order to confirm the dx of Post-Dural Puncture/Intracranial Hypotension?
nothing! dx is based on hx and PE
50
If imaging is ordered on Post-Dural Puncture/Intracranial Hypotension, what will it show?
diffuse enhancement of the meninges
51
What is the tx for Post-Dural Puncture/Intracranial Hypotension?
Recumbency (lay flat) for 18–24 hours IV fluids Non opiate analgesics +/- caffeine Most headaches resolve within one week without treatment Consult anesthesiology to determine the need for epidural blood patch
52
What are 3 common ways a pt usually gets a brain abscess?
spreads directly from the blood, infection somewhere in the head, recent neurosx or trauma
53
What is the composition of a brain abscess?
An inflammation of the brain that develops into a central pus-filled cavity surrounded by a layer of granulation tissue and an outer fibrous capsule
54
What is the clinical presentation of a brain abscess? What are the 3 major ones?
*HA *Focal neurologic deficits *Fever Seizure S/S of increased ICP papilledema, N/V, change in LOC, confusion
55
What needs to be included as part of your w/o for a pt with a brain abscess?
CT/MRI WITH CONTRAST- diagnostic CBC, CMP, CRP/ESR, blood cultures
56
When do you need to obtain blood cultures in a pt with a brain abscess? What procedure do you NOT want to do? Why?
Blood cultures x 2 - before first abx dose avoid LP: due to risk of brain herniation
57
What is the choice of abx for a brain abscess based on? give the 3 options. When would you want to give steroids?
abx based on the suspected source of the abscess! Odontogenic source - IV PCN G (alt. ceftriaxone PLUS metronidazole) Post-neurologic procedure - vancomycin PLUS ceftazidime All others - Cefotaxime (alt. ceftriaxone) PLUS metronidazole 500 milligrams IV every 6 h Steroids ONLY IF significant peri-abscess edema with associated mass effect and increased ICP ADMIT pt and consult neurosx!!!
