Difficulty: EasyPediatric Neurologic Disorders

A 10-month-old boy is brought to the emergency department by his parents after experiencing a sudden episode of generalized shaking that lasted for approximately 1 minute. During the episode, the patient's eyes rolled back, and he was unresponsive to his parents' voices. By the time they arrived at the emergency department, the shaking had stopped and he had fully regained consciousness. Over the past two days, the infant has had clear rhinorrhea, a mild cough, and a tactile fever. His temperature is 39.2°C (102.6°F), heart rate is 145/min, blood pressure is 90/60 mmHg, and respiratory rate is 42/min. On physical examination, the infant is awake, alert, and playfully reaching for the physician's stethoscope. Auscultation of the lungs reveals diffuse bilateral expiratory wheezing. Neurologic examination shows normal muscle tone, symmetric reflexes, and no focal deficits. The parents note that he recently started pulling himself up to a stand and says "dada" and "mama". Which of the following is the most appropriate next step in the management of this patient?

  1. Reassurance and supportive careAnswer
  2. B
    Administration of oral dexamethasone and inhaled albuterol
  3. C
    Initiation of empiric intravenous ceftriaxone
  4. D
    Referral for a comprehensive developmental delay assessment
  5. E
    Administration of the live-attenuated measles, mumps, and rubella (MMR) vaccine

Answer

Reassurance and supportive care
The correct approach is to offer reassurance and supportive care. This child's presentation—a brief, generalized seizure with a fever, followed by a rapid return to a normal neurologic baseline—is diagnostic of a simple febrile seizure. Additionally, his coryza and wheezing indicate acute viral bronchiolitis as the source of the fever. Because simple febrile seizures do not cause brain damage, epilepsy, or developmental delay, and bronchiolitis is a self-limiting viral illness, no further diagnostic workup (like lumbar puncture or EEG) or targeted pharmacological interventions (like antibiotics or antiepileptics) are indicated.

Step-by-Step Solution

1
Analyze the seizure characteristics and presentation.
The seizure was generalized, lasted less than 15 minutes (only 1 minute), occurred in the presence of a fever, and the patient quickly returned to his neurologic baseline.
These are the hallmark diagnostic criteria for a simple febrile seizure, which is benign.
2
Evaluate the underlying cause of the fever.
The child has clear rhinorrhea, cough, low-grade fever, and diffuse bilateral wheezing.
This clinical picture strongly suggests a viral illness, most likely viral bronchiolitis, which is common in this age group.
3
Determine the appropriate management plan based on both diagnoses.
The best step is to provide supportive care and reassure the parents.
Neither simple febrile seizures nor viral bronchiolitis typically require extensive diagnostic testing, antibiotics, or daily medications. Supportive measures (e.g., hydration, antipyretics for comfort) are sufficient.

Key Concept

Simple febrile seizures are benign, generalized seizures lasting less than 15 minutes that occur in children aged 6 months to 5 years with a fever. The most appropriate management is identifying the source of the fever, ensuring the neurologic exam is normal, and providing parental reassurance and supportive care.
