  29. Neurologic Examination Cranial Nerves I: not elicited II: 2-3mm pupils, equally reactive to light III,IV,VI: EOM’s intact V: corneal reflex present V1, V2, V3 intact (turns to touch) VII: no facial asymmetry VIII: turns to sound IX, X: gag reflex present XI: turns head from side to side XII: tongue midline

  30. Case Presentation Admitting Impression, Salient Features, Differentials, Course in the Ward

  31. Admitting Impression • Benign Febrile Seizure secondary to pneumonia

  32. Salient Features • 13 month old, female • Fever (intermittent, undocumented) • Convulsion • 2-3 minutes • General tonic-clonic • Unproductive cough and colds • Tachypneic, tachycardic • Bilateral lung crackles • Normal neurologic exam

  33. Differential Diagnosis

  34. Differential Diagnosis

  35. Course in the Ward ER T: 40.1 oCCR: 138RR: 35 awake, in mild cardiorespiratory distress rales on bilateral lung fields D5LR Paracetamol 10mkd

  36. Course in the Ward ER CBC: normal Urinalysis: pus cells – 2-4

  37. Course in the Ward 1st Hospital Day

  38. Course in the Ward 2nd Hospital Day

  39. Course in the Ward 3rd Hospital Day

  40. Course in the Ward 5thHospital Day

  41. Course in the Ward 6th Hospital Day

  42. Final Diagnosis • Benign Febrile Convulsion secondary to Pneumonia

  43. Case Discussion

  44. 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

  45. 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. Nooruddin R Tejani, MD, Assistant Professor, Department of Emergency Medicine, SUNY Health Sciences Center Brooklyn; Director, Pediatric Emergency Medicine, Downstate Medical Center

  46. Pathophysiology High frequency burst of action potentials Increase neuronal excitability Endogenous Pyrogens (interleukin 1 beta) Spread of seizure activity! Loss of surround inhibition Seizure propagation American Epilepsy Society – 10/04

  47. 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 seizures CPG on First Simple Febrile Seizure

  48. 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 disorder CPG on First Simple Febrile Seizure

  49. 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 CPG on First Simple Febrile Seizure
