Ix for febrile convulsion
Diagnosis is clinical
• Tests may be required to identify source of fever
. Investigations to consider:
- Lumbar puncture
- Rule out meningitis
- Viral studies
- Blood culture
- Bacteremia?
- EEG
- Brain MRI
- Consider in child with abnormal development, history or neurological examination.
- FBC
Differential Diagnosis for febrile seizure?
- Bacterial meningitis
- Viral meningitis
- Viral encephalitis
- Epileptic seizure
- Hot water epilepsy : Focal seizure after bathing in hot water.
- Breath-holding spells : Afebrile infant with apneic attack and short generalised episodes of jerking after crying spell
What examinations would you for suspected febrile seizure?

b) 0.6 per 1,000
c) 0.1 per 1,000
d) 0.3 per 1,000
d) 0.3 per 1,000
Sudden Infant Death Syndrome’ is also known as?
cot death
What is ‘Sudden Infant Death Syndrome’
Defined as ”The sudden death of an infant under 1 year, which remains unexplained after thorough case investigation including autopsy, examination of scene and review of history”
Sudden Infant Death Syndrome’ is of the leading cause of
post-neonatal infant death
WHat is Triple-Risk Hypothesis
The triple-risk hypothesis explains SIDS by three factors converging to result in infant death.
What are the three factors in Triple-Risk Hypothesis SIDS
- A vulnerable infant - prematurity, low birth weight
- In a critical period during homeostatic control development
- An exogenous stressor – smoke exposure, sleep, over-heating
