LAST PEDS! Flashcards
Define Epilepsy
recurrent, UNPROVOKED seizures
SZR that arises from one region of the brain cortex
Focal/ partial SZR
SZR that arises form both hemispheres of the brain
Generalized
4 categories of SZR
Focal
Generalized
Unknown onset
Unclassified
A SZR that begins diffusely think
Generalized
Tonic clonic, Absence, Febrile
Difference between simple and complex focal SZRs
Simple: no altered consciousness
Complex: altered consciousness
MC cause of SZRs in kids
Idiopathic is 75% of all cases
Tx for Generlizedd Motor SZRs
oxcarbazepine or levetiracetem
How to DDX tics vs SZR
Tics are partially under voluntary control
Focal SZRs are preceded by..
Aura prodrome
What are automatisms
unconscious actions seen in focal complex SZRs
Automatic movements commonly of mouth or extremities
Age of onset for Absence SZRs
Around 5-8 yrs old
A 5 yr old haas a brief period of eye flutter and upward eye rolling
Think what SZR D/o? And what is the treatment?
Absence SZR
Treat with ethosuximide
Do absence SZRs present with post ictal phases
NO!
->immediate resumption of activity
MC cause of SZR from age 6months to 5 yrs
Febrile SZR
What is the DDX for simple febrile SZR compared to Complex/Atypical Febrile SZR
Simple: Tonic/Clonic lasts less than 15 min and only occurs x1 in 24 hours
Complex/Atypical: Focal S/s lasts longer than 15 min, recurres several times in 24 hours and/or child has preexisting nuero d/o
What should be ruled out in SZR evaluation
need to rule out meningitis, encephalitis, brain abscess
If focal neurologic signs or papilledema → CT before LP
MRI is imaging modality of choice for detecting brain lesions in subacute setting (in the ED -> CT)
Febrile SZR MGMT
USUALLY NO INTERVENTION NEEDED
High risk pt: Rectal Diazepam to abort SZR >5min
Daily AntiSZR medication NOT needed unless at risk for epilepsy
Do Antipyretic’s prevent Febrile SZRs
Antipyretics during febrile illnesses does NOT prevent febrile seizures
SZR for 30 min or more…
Status Epilepticus
Status Epilepticus MGMT
ABCs
ECG + O2/Pulse Ox
IV access -> Benzo
LABS:
Glucose, BMP, Therapeutic Rx level, Toxicology, CBC+ platelets and Differential
Proper disposition for Status Epilepticus MGMT
PICU for monitoring
Head aches in the morning
Think
Tumor
Headache Red Flags
“Worst headache of my life” → subarachnoid hemorrhage
Morning headache → tumor
Pain awakens child at night
Chronic, progressive headaches (most ominous headache pattern)
Abnormal/focal findings on neuro exam
Changes w/ body position
Recurrent vomiting (especially in morning)
No previous family history
=GET IMAGING!
A younger pt iwth a bilateral, bifrontal headache
Think
Migraine
Migraine Headache
Common recurrent headache in peds
Focal, bilateral and bifrontal
Seeking dark quiet rooms
N./V, pallor, photophobia, phonophobia
+/- Aura
If a kid presents with headache but no FMHx of headaches
Think
A worse secondary cause
Because 90% have a 1st or 2nd degree relative with recurrent headaches
DDX for 2nd Headaches
Head trauma Viral illness Sinusitis Medication overuse headaches Increased ICP—mass, vascular malformation, pseudotumor cerebri
Headache that is worse when lying down or early in the AM
Think
Secondary cause to headache
After a CT w/u for headache what is the next step
If CT negative → obtain a lumbar puncture → measure opening pressure & evaluate for RBCs, WBCs, protein, glucose, or xanthochromia
What is the best way to find posterior fossa lesions
Brain MRI with/without gadolinium contrast (study of choice)
1st line Tx for Migraines
Acetaminophen or NSAIDs (ibuprofen or naproxen)
Adjunct therapies: hydration & antiemetics
2nd line: Triptan agents
What are the contra/I for using triptans for migraines
Focal neurologic deficits with migraines
Basilar migraine signs (syncope) → stroke risk
What drug can you not give to peds with migraine with aura
NO OCPs!
When to start migraine prophylaxis
If more than 1 disabling headache per week
What is pseudo tumor cerebri
AKA idiopathic intracranial hypertension
Elevated ICP with normal brain imaging
S/s : Diplopia, abducens palsy, transient visual obscurations, papilledema
MC Cause: idiopathic
Tx for Idiopathic Intracranial hypertension
Untreated? permanent visual field loss!
Treatment: acetazolamide (or other diuretics), topiramate, or corticosteroids
(Also wt loss and remove any triggering medications)
Retrograde vs Anterograde amnesia
Retrograde amnesia: inability to recall events leading up to trauma
Anterograde amnesia: inability to form new memories after trauma
Variable duration: length of amnesia typically correlates w/ severity of trauma
Highest timeline risk for concurrent concussions
Increased in the 1st 10 days after concussion occurs
Prognosis of SZR with concussions
At time of injury: due to cortical stimulation → excellent prognosis
Within 7 days: typically due to localized edema or contusion → good prognosis
After 7 days: attributed to glial scarring → leads to epilepsy
Role of CT in concussion MGMT
CT not used to diagnose concussion, but rather to rule-out serious traumatic brain injury (i.e., hemorrhage)
What is second impact syndrome
Acute, sometimes fatal brain swelling occurring when a second concussion is sustained before complete recovery from a previous concussion
May cause rapid increase in ICP which is impossible to control
3 deaths every 2 years
Return to play guidelines for concussion
- No activity
- Light aerobic
- Sports specific excercise
- Non contact sports play
- Full contact practice
- Game play
Each stage should be a minimum of 24 hours without s/s to move to the next stage
Most at risk for Post concussive syndrome
Risk factors: younger age, level of play, ongoing clinical symptom, chronic neurobehavioral impairments, catastrophic outcomes (i.e., subdural hematoma)
S/s: Hallucinations, Dizziness, HA, Unclear thinking, sleep d/o
Can last weeks and effect school performance
Refer to NEURO!
Stage IV sleep….
REM (rapid eye movement)
Active, awake-like EEG pattern & muscle atonia
Active sleep: REM sleep in neonates
Who sleeps longer, bottle fed or breastfeed babies
Bottle-fed babies generally sleep for longer periods (2-5 hr bouts) than breastfed babies (1-3 hr).Sleep periods are separated by 1-2 hr awake.
Should peds less than 1 years old
Share the bed
American Academy of Pediatrics issued a revised recommendation in 2016 advocating against bed-sharing in the 1st yr of life, instead encouraging proximate but separate sleeping surfaces for mother and infant for at least the 1st 6 mo and preferably 1st yr of life.
Best sleeping position for babies
On back, firm mattress, do not use pillows or comforters
NML sleep patterns for infants 2-12 months old
great individual variability
At what age does the capacity to self soothe start?
capacity to self-soothe begins to develop in the 1st 12 wk of life and is a reflection of both neurodevelopmental maturation and learning.
NML nap time for toddlers
Naps decrease from 2 to 1 nap at average age of 18 mo.
When do nighttime fears start to develop
1-2 years old
Have a good night routine to abate this
Should preschoolers cosleep
Persistent cosleeping tends to be highly associated with sleep problems in this age-group.
Sleep hygiene for 6-12 years old
School and behavior problems may be related to sleep problems.
Avoid media and electronics at bed time
What is sleep onset associated insomina
child awakens under conditions different from those experienced as they fell asleep and cannot return to sleep independently
Leads to sleep d/o
What is limit-setting subtype of insomina
Bedtime resistance or refusal due to a caregiver’s unwillingness or inability to enforce bedtime rules & expectations
Nighttime fears → also common cause of bedtime refusal
When do night terrors occur
When do nightmares occurs
Terrors: 1st 1/3 of sleep
Nightmares: last 1/3 of sleep
Circadian rhythm disorders in adolescence
Exaggerated delayed sleep phase
Leads to inability to arouse in the mornings & failure to meet sleep requirements

Tx options for VSD
~One third close spontaneously
Initial treatment
(moderate-large VSDs):
diuretics (± digoxin)
& afterload reduction
Poor growth, failure to thrive (FTT) or pulmonary HTN despite treatment → closure required (usually surgical)
When do you do Tx correction for ASD
