Q

What are the indications for neuroimaging for a child with HA?

A

1) NOT indicated on routine basis in children with recurrent HA and normal neurological exam
2) should be considered in children with abnormal neurological exam, coexistence of seizures or both
3) should be considered in children with historical features to suggest recent onset of severe HA, change in HA type, or other associated features suggesting neurological dysfunction

Q

What preventative treatment do we have for HA?

A 
antiepileptics 
beta blockers 
CCB 
antihistamines
antidepressants 
no FDA approved indication for HA in children

considered for >/=4 days of debilitating HAs/month

Topiramate shown more effective than placebo in management of pediatric migraine

18
Q

Seizure epi

A

1% prevalence of epilepsy
3% prevalence of febrile seizures
generalized seizures are more common in children than adults

19
Q

How are seizures dx?

A

Mainly on HX

EEG - if normal: 
- does NOT r/o epilepsy 
if abnormal: 
-does not dx epilepsy unless seizure is recorded 
-helps classify type of epilepsy
20
Q

What are the different types of generalized seizures?

A 
tonic clonic 
tonic 
clonic
absence
atonic
mytonic
21
Q

What are the different types of focal seizures?

A

simple partial
complex partial
secondary generalized

22
Q

Febrile Seizure

A

convulsion associated with an elevated temperature greater than 38C
3 months - 6 years

MC neuro disorder of infants and young children

peak incidence 12-18 months

23
Q

What is the MC neuro disorder or infants and young children?

A

febrile seizure

24
Q

What are the risk factors of febrile seizures?

A

peak temperature during illness
1st degree relative with febrile seizures
neurodevelopmental delays
increased exposure to herpesvirus 6
vaccinations with DTaP, influenza may be associated

almost 50% have NO identifiable risk factor

25
Q

What are the two types of febrile seizures?

A

Simple febrile seizure (MC)

  • generalized
  • duration less than 15 minutes
  • single seizure in a 24h period

Complex febrile seizure

  • focal clinical manifestation
  • duration longer than 15 minutes
  • more than one in 24 hour
26
Q

When is an LP appropriate for febrile seizures?

A

infants <12 months

meningeal signs or sxs or other clinical features that suggest a possible meningitis or intracranial/CNS infection

27
Q

What is the treatment for febrile seizures?

A

antipyretics do NOT help

rectal diazepam can be used in short term for children with recurrent or prolonged febrile seizures

28
Q

What is the prognosis of febrile seizures?

A

education, reassurance, and counseling
risk of recurrence ~30-50%
no increased risk of developmental or scholastic problems
risk of epilepsy increases from 1% - 2.5%
-family history of epilepsy
-complex febrile seizures
-neurodevelopmental abnormalities

29
Q

Status epilepticus

A

at least 30 minutes of continuous seizure activity or intermittent convulsive activity without regaining consciousness

1/3 - initial event
1/3 established epilepsy
1/3 other (trauma, stroke, meningitis, ingestion)

30
Q

Broselow tape

A

color coded tape
each color corresponds to estimated weight class
often paired with pediatric color coded crash cart

obesity should be taken into account

31
Q

What is the management of status epilepticus?

A

ABC
IV access
check blood glucose

Benzodiazepines - first line
-Lorazepam (ativan) preferred choice in status epilepticus because rapid (3-5 min) onset and long (12-24 hour) half life

  • diazepam (valium) - rectal
  • midazolam (versed) - IM

Benzos may be repeated every 5 minutes for a max of 3 doses
if still seizing after 3 doses of Benzos –alternative treatment
Phenytoin (Dilantin) is next drug of choice
-given slowly to avoid cardiac dysrhythmia and hypotension

Phenobarbital added if third medication is needed (risk of respiratory depression - be prepared to intubate)

32
Q

What do you do after giving 3 doses of ativan over 15 minutes to a child having a seizure?

A

given phenytoin
-given slowly to avoid cardiac dysrhythmia and hypotension

Phenobarbital added if third medication is needed (risk of respiratory depression - be prepared to intubate)

33
Q

Epilepsy definition

A

2 or more unprovoked afebrile seizures

34
Q

What is the treatment of epilepsy treatment?

A

antiepileptic drugs recommended after 2 or more afebrile seizures

partial complex: Oxcarbamexpine, levetiracetam

generalized:
- tonic clonic - lamotrigine, valproate, topiramate
- absence - valproate

antiepileptic therapy continued for at least 2 years after the last seizure

35
Q

Concussion

A

a brain injury defined as a complex pathophysioloigcal process affecting the brain, induced by traumatic biomechanical forces
often referred to as a “mild TBI”

36
Q

Who is at highest risk of concussion?

A

middle and high school age children

37
Q

What are the signs and sxs of concussions?

A

+/- preceding loss of consciousness

min to hours:
HA, dizziness (vertigo or imbalance), lack of awareness, N/V

hours to days:
mood and cognitive disturbances
sensitivity to light and noise
sleep disturbances

38
Q

SAC Tool

A

standardized assessment of concussion tool

  • orientation
  • immediate memory
  • concentration
  • delayed recall
  • neurologic screening
  • exertional maneuvers
  • includes a graded sxs checklist, a brief neurologic examination, and records the presence of post-traumatic and retrograde amnesia
39
Q

PECARN rule

A

findings associated with very low risk of significant traumatic brain injury in children

40
Q

Return to school rule for TBI?

A

may return after they can concentrate on a task and tolerate visual and auditory stimulation fro 30-45 minutes

41
Q

Return to play rule for TBI?

A

Zurich guidelines for return to play following concussion

the following are requirements for return to play protocol:

  • successful return to school
  • sxs free and off any medications prescribed to treat the concussion
  • normal neurologic examination
  • back to baseline balance and cognitive performance measures
42
Q

Zurich guideline for return to play after TBI

A

0 - no activity
1 - light exercise
5 - normal game play
