4

While most children ____ y/o can cooperate with the instructions for the fundoscopic exam, if you are really entertaining the possibility of ICP, they should have a dilated fundoscopic exam by an ophthalmologist.

4y/o and older

5

Hx questions for pediatric seizures

1. Alteration in awareness/consciousness*
2. Aura
3. Witnessed movements/video

9. FHx of seizures
10. Adolescent- EtOH, drugs, sleep deprivation

6

__ and __ are very suggestive of a true seizure

incontinence and post-ictal state

7

In adolescents it is important to ask about __, __ and ___, as all of these are implicated both in breakthrough seizures in those patients who have a true seizure disorder, but __ and ___ can also cause a provoked seizure in a non-epileptic patient.

alcohol, drugs and sleep deprivation


alcohol and drugs

8

Describe the presentation of infantile spasms

1. peak age 4-7 months
2. exaggerated moro-like movements

9

Describe the presentation of febrile seizures

1. 6 mo-5 years
2. General tonic-clonic movement
3. Complex febrile seizure

10

Describe the presentation of absence seizure

1. 3-15 years

3. No post-ictal state
4. Classic EEG of 3Hz spike/wave pattern

11

Describe the presentation of simple or complex partial seizures

1. Any age
2. Complex: Focal start, progressing to generalized seizure
3. Simple: consciousness not altered initially

12

Describe the presentation of Benign Rolandic epilepsy

1. 5-15 years, remits in puberty
2. Focal motor seizure involving face, hand
3. Usually during sleep or upon awakening
4. Classic EEG pattern of central temporal spikes, no imaging or treatment usually needed

13

describe the prognosis for infantile spasms

Infantile spasms do not have a particular favorable prognosis, so they are important not to miss, delaying treatment.

14

complex febrile seizure is defined as

more than 1 febrile seizure occurring within 24 hours, febrile seizures lasting longer than 15 minutes or that have focal features.

15

The difference between simple and complex partial seizures is

the intact awareness in patients with simple partial seizures.

16

This type of seizure is particularly concerning for the possibility of a brain lesion as the focality of motor activity indicates a specific area of the brain is emitting the aberrant electrical activity.

complex febrile seizure

17

What does the EEG pattern look like for Benign Rolandic Epilepsy

-central temporal spikes,
*no imaging or treatment usually needed

18

What does the EEG pattern look like for absence seizures

3Hz spike/wave pattern

19

Describe acute management for febrile seizures

1. safety measures to ensure that they do not hurt themselves
2. oxygen
3. Occasionally, if a child is still seizing after 5 minutes, it may be necessary to contact 911.
4. If the office has supplies, it is possible to use rectal diazepam and attempt IV access.
-The patient who require 911 will likely continue their evaluation in the ED.
-For the patients who are able to remain in your office because their seizure stopped spontaneously after a few minutes, which is 99% of them, you will need to proceed through the evaluation for fever.

20

Keep in mind that children < 1 y/o or unimmunized should have a ___ if they have had a seizure.

LP

21

For children <6m, you should consider ____, and these children should probably be evaluated in the ED.

an electrolyte panel

22

The only additional consideration in a child >12m is a ____, if anything about the history suggests access to pain medications, sleeping pills, or their post-ictal phase seems prolonged.

urine toxicology screen

23

Therefore, most children ___ are evaluated for their seizure and fever in the ED.

<12m

24

Returning then to the PCP role of follow-up after a febrile seizure, the role is really ___

Anti-pyretics

29

For children who have recurrent febrile seizures, it is possible to prescribe ___ so that parents feel they have some way to stop a febrile seizure

rectal diazepam

30

What patient education should you give about management of febrile seizures

1. place their seizing child in a place where they cannot injure themselves,
2. do not try to restrain them,
3. time the seizure and if it reaches 5 minutes, call 911.
4. Otherwise, when the seizure ends, take and document the fever, give an anti-pyretic and have the child evaluated with a few hours at the clinic or ED for the cause of the fever.

31

32

Describe the ED management of 1st non-febrile seizures

focuses on ruling out a provoked seizure*

2. possibly an LP or
3. a CT scan of the head (looking for ICP, head trauma, lesions or bleeds)
4. f/u w/ PCP for w/u of possible epilepsy

33

Non-febrile or unprovoked seizures will likely require __-

an MRI to look for intracranial pathology.

*CT’s are not a good modality for looking for small tumors, which is why an MRI is superior.

34

PCP w/u of non-febrile seizure

1. careful history and neuro exam
2. MRI for intracranial pathology
3. order EEG w/in 2 weeks-- ask the protocol of the EEG lab that you clinic utilizes. Sometimes, they require that you provide the patient with a prescription for sedatives that the parent fills before the appointment and they will administer when the child arrives

**No anti-epileptics-- leave for neurologist
4. A referral to the neurologist should occur if the EEG or MRI are abnormal, the neuro exam is abnormal, or if the history is concerning

35

For children <4y, who will later be determined to have epilepsy, __% of their initial EEG’s are negative.

50%

*Further seizures will then send them back for another EEG, increasing the likelihood of seeing pathology on the EEG

36

Seizure precautions

1. no swimming w/o a buddy
2. no scuba diving
3. no activities involving heights where a fall could result in serious injury.
4. Laws about driving differ by state, but generally, patients need to be seizure-free for 6 months with or w/o meds in order to be able to drive (CO does not have this law nor a mandatory reporting protocol for patients with seizures)

37

Concerning sz hx
