RESUMEN
INTRODUCTION: Alpha lipoic acid is a powerful antioxidant widely used for the supplementary treatment of diabetic neuropathy. Intoxication with alpha lipoic acid is very rare. There is no reported dose of safety in children. CASE REPORT: A 14-month-old previously healthy girl was referred to our hospital with the diagnosis of drug intoxication. She was admitted to the emergency department with lethargy and continuing involuntary movements for several hours after she had ingested an unknown amount of alpha lipoic acid. On admission she was lethargic and had myoclonic seizures involving all extremities. She had no fever and laboratory examinations were normal except for mild metabolic acidosis. The seizures were unresponsive to bolus midazolam, phenytoin infusion and levetiracetam infusion. She was taken to the pediatric intensive care unit with the diagnosis of status epilepticus. After failure of the treatment with midazolam infusion she was intubated and thiopental sodium infusion was started. Her myoclonic seizures were controlled with thiopental sodium infusion. After 48 h intubation and mechanical ventilation thiopental sodium was gradually reduced and then stopped. Following the withdraw of thiopental sodium, she was seizure free on her discharge on the 8th day. CONCLUSION: Alpha lipoic acid and derivatives cause side effects in children like refractory convulsions. They are frequently rendered as vitamins by diabetic patients and are left at places where children can easily access them. Therefore, when faced with refractory convulsions in children who have had no disease before, intoxication by medicaments with alpha lipoic acid should be taken into consideration.

Our study sought to identify early predictive factors of medically intractable childhood epilepsy. A cohort of epileptic children from the city of Mersin was retrospectively investigated. All patients received care from the same Department of Pediatric Neurology. The epileptic cohort was divided into a drug-responsive epilepsy group and an intractable epilepsy group. Intractable epilepsy is defined as continued seizures in children despite adequate therapy with two or more antiepileptic drugs for more than 18 months. Strong univariate association was observed between intractability and several factors: age of onset, high initial seizure frequency, symptomatic etiology, mixed seizure types, previous history of status epilepticus, febrile and neonatal seizures, mental and motor developmental delay, multiple seizures in 1 day, electroencephalogram abnormalities, magnetic resonance imaging findings, and specific epileptic syndromes. Logistic regression analysis revealed that a previous history of epilepticus status, abnormal electroencephalogram results, and multiple seizures in 1 day comprise independent predictors of medically intractable childhood epilepsy. We suggest that medical intractability in childhood epilepsy can be predicted by monitoring these factors. Along with early prediction, alternative therapies may be designed to provide patients better seizure control and quality of life.
