Course in the Ward

1st Hospital DayS O A P

-Good suck

T: 36.5oC CR: 120 RR: 36-Awake, with good cry-In mild cardiorespiratory distress-no seizures-With febrile episodes

-No retractions-Fine crackles, bilateral

-She is afebrile but has febrile episodes recorded

-Patient is tachycardic and tachypneic.

-IV Fluids-Ampicillin -Paracetamol for fever-monitor vital signs-diet as tolerated-for CSF culture

2nd Hospital DayS O A P

T: 37.6oC CR: 110RR: 34-with good cry-In mild cardiorespiratory distress-no seizures


-still no episodes of seizures and fever

-still tachypneic

-Continue medications-monitor vital signs-diet as tolerated-for CSF culture

3rd Hospital DayS O A P

T: 36.6oC CR: 108 RR: 30-not in cardiorespiratory distress-no seizures


Chest X-Ray-bilateral lung PN w/ non-specific lymphadenopathy suggest follow-up study after treatment to r/o primary infection PTB

-absence of seizures-responding well to medications-the patient is no longer tachypneic-with no more febrile episodes

-continue medications-monitor vital signs-Diet as tolerated-For CSF culture

CSF analysis-clear, sugar 3.3s (N), protein 27.6 (N), cell count 0

-no more seizure episodes-resolution stage of pneumonia-CSF analysis rules out meningitis

May go home

Final Diagnosis

Benign Febrile Convulsion secondary to Pneumonia

Case Discussion

Definition/ Clinical Manifestations

Simple Febrile Seizures Ages 3 months – 6 years Axillary temperature 37.8oC or

greater Generalized tonic-clonic seizures Less than 15 minutes Does not recur within the same

febrile illness Normal neurologic exam No underlying CNS infection or

abnormality

CPG on First Simple Febrile Seizure

Incidence

2% - 5% have febrile seizures by 5 years old (US)

5% -10% for India, 8.8% for Japan, 14% for Guam,0.35% for Hong Kong, and 0.5-1.5% for China.

Pathophysiology

(interleukin 1 beta)

High frequency burst of action

potentials

Seizure propagation

Loss of surround inhibition

Spread of seizure activity!

American Epilepsy Society – 10/04

Diagnostics

Lumbar puncture should be performed in all children below 18 months for benign febrile convulsions For >/= 18months, it is recommended in

the presence of clinical signs of meningitis

Neuroimaging studies should not be routinely performed in children for benign febrile seizuresCPG on First Simple Febrile

Seizure

Treatment

Antipyretic use Used to lower fever and should not be relied

upon to prevent the recurrence of febrile seizures

Antiepileptic drug use (continuous anticonvulsant) Not recommended in children after a simple

febrile seizure. It can reduce the recurrence of febrile

seizures, but its adverse side effects do not warrant their use in this benign disorderCPG on First Simple Febrile

Seizure

Treatment

Antiepileptic drug use (intermittent anticonvulsant) Not recommended for the prevention of

recurrent febrile seizures There is no difference in the risk of

seizure recurrence in children receiving intermittent diazepam and placebo


Prognostic Evaluation

Electroencephalogram (EEG) Should not be routinely requested in

children with a benign febrile seizure There is no evidence that EEG can

predict future incidence of epilepsy Presence of abnormalities in the EEG

does not change the recommendation the use of anticonvulsants


Prognosis

Simple febrile seizures may slightly increase the risk of developing epilepsy, but they have no adverse effects on behavior, scholastic performance, or neurocognition.

Children with febrile seizures have a slightly higher incidence of epilepsy compared with the general population (2% vs 1%).
