MD1TALK
Febrile convulsion🌟
Def: seizure activity associated with febrile illness in absence
of : CNS infection, or other neurological cause ,severe metabolic
disturbance.
Age: 6 mo - 6 yr And with a peak at 14 to 18 month. *most
common neurologic disorder* (some reference write 5y)
causes : All is infectious
URTI , UTI
ROSEOLA: caused by human herpes virus 6 marked by several
days of high grade fever, followed by a distinctive rash just as the
fever breaks (like the rainbow after the rain)
ACUTE OTITIS MEDIA
DXX : as causes of seizure
1) Infection of CNS
2) Imbalance of Severe electrolyte
3) In-Born-error of metabolism
4) Intracranial mass
5) sepsis
Dx is made by Hx and exclusion
Febrile convulsion🌟🧠
MD1TALK
Type Typical (simple ) Atypical (complex)
Age 6 months to 6 years any age
Onset Occur early when core Occur more than once in 24
temperature reaches 39 C or hr
greater
Duration ≤15 min >15 min
Type of GTC seizure → followed by Focal seizure
seizure a postictal period of
drowsiness
Neurological Normal Abnormal neurological
exam examination
, MD1TALK
Investigation :
Typical: not required
Atypical: required to do
1) EEG
2) Toxicology screening
3) electrolytes
4) CT or MRi
5) CSF study to rule CNS infection:
Atypical febrile convulsion
age < 18 month ? to exclude sepsis (new data suggest a 12m period
is the new cutoff)
Routine treatment:
1) Search for the cause of fever
2) Control fever (avoid excessive clothing, encourage fluids, and
antipyretics)
prognosis :
1) Excellent prognosis in most children
2) Risk of recurrence of febrile convulsion:
3 Major: Age < 1 year– Duration of fever < 1 day — Fever 38-39 C
6 Minor:
Family history of febrile seizure.
Family history of epilepsy.
Complex febrile convulsion.
Male gender
day care
Low serum sodium
Risk of epilepsy development:
-1~2% in the general population , increase up to 9% when two or more
risk factors are present :
1) Simple febrile seizure 1% → least RF
2) Neuro-developmental abnormalities 33% → Highest RF
3) Positive family history of epilepsy 18%
4) complex febrile seizure 29%
5) Fever <1 hr before febrile seizure 11%
6-Recurrent febrile seizures 4%
