Insights
Complex partial status epilepticus (CPSE) in children can be challenging, with some cases triggered by improper medication. Prompt diagnosis and appropriate treatment lead to favorable seizure prognoses in most pediatric patients.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Neuroscience
Background:
- Complex partial status epilepticus (CPSE) is a prolonged epileptic condition.
- Understanding CPSE in pediatric populations is crucial for effective management.
Observation:
- Five pediatric patients (4-8 years) with CPSE were studied.
- Four patients had pre-existing conditions, including mild developmental delays.
- CPSE was iatrogenically induced in two patients due to suboptimal antiepileptic drug management.
Findings:
- Clinical presentations varied, with automatisms in three patients and one experiencing syncope with amaurosis.
- Electroencephalography (EEG), including video-EEG, confirmed persistent focal epileptic activity in four patients.
- Intravenous diazepam was effective in three patients, though brief EEG localizations persisted.
Implications:
- Appropriate antiepileptic drug selection and management are critical for treating pediatric CPSE.
- Most patients achieved favorable seizure prognoses with tailored treatment.
- One patient exhibited intractable seizures despite therapeutic interventions, highlighting treatment challenges.
Abstract:
We report 5 pediatric patients (2 male, 3 female; age range: 4-8 years) with complex partial status epilepticus (CPSE). Four patients had previous illnesses and mild motor or mental retardation. In 2 patients, CPSE was induced by inappropriate management or selection of antiepileptic drugs. Clinical features varied and automatisms were observed in 3 patients. In 1 patient, decreased physical tone with syncope and impaired consciousness with amaurosis were observed. The episodes of CPSE were continuous in 3 patients and recurrent in 2 patients. In 4 patients, ictal electroencephalographic (EEG) findings, including video-EEG analyses of 3 patients, demonstrated persistent focal epileptic features. Intravenous diazepam abolished CPSE in 3 patients with brief periods of definite EEG localizations remaining. In 4 patients, seizure prognoses were favorable after appropriate treatments; in 1 patient, seizures were intractable even after antiepileptic drug administration.
