pyridoxine dependent seizure have been recornized as a rare and important cause of intractable seizure in neonates and infants.prompt diagnosis and treatment can stop and prevent these seizure and consequential developmental disabilities.furthermore it can eliminate the unnecessary administration of anticonvulsant medications and thier side effects.the paitient was 7 months old infant who was r...

Intractable epilepsy is a common clinical problem in pediatrics and approximately 13% of children with epilepsy experience intractable seizures. To determine the efficacy of pyridoxine in treating seizures, 30 infants and children with recurrent seizures were enrolled in the present study. All of them were treated with high-dose oral pyridoxine (40 mg/kg/day), as an adjunct to antiepileptic...

OBJECTIVE To study the epidemiology of pyridoxine dependent seizures and other forms of pyridoxine responsive seizures. DESIGN Monthly notifications to the British Paediatric Surveillance Unit over two years. Questionnaire follow up. SETTING UK and the Republic of Ireland. PATIENTS Children aged 15 years or younger whose seizures respond to pyridoxine. INTERVENTIONS None. MAIN OUTCOME...

Normobaric supplemental oxygen can prolong seizures not caused by hyperbaric oxygen therapy. In addition, hyperbaric oxygen therapy can cause seizures. The mechanism of hyperbaric oxygen-induced seizures is unknown. We hypothesized that pretreatment with pyridoxine may delay the onset of hyperbaric oxygen-induced seizures, recognizing that pyridoxine is already an antidote for some epileptogeni...

We report 4 infants with pyridoxine dependent seizures who had clinical features that led to diagnostic uncertainty. Their clinical course was unusual in 1 or more of the following: later onset of initial seizures; a seizure free period after taking of anticonvulsants, but before taking of pyridoxine; a long remission after withdrawal of pyridoxine; and atypical seizure type. This report illust...

Pyridoxine-dependent epilepsy (PDE) is a rare autosomal recessive enzyme defect in the vitamin B6 metabolism characterized by intractable seizures which are usually resistant to all antiepileptic drugs but respond to pharmacological doses of pyridoxine. We present the clinical and molecular genetic findings of two patients with c.1597_1597delG mutations in ALDH7A1 gene. There are different clin...

Eight children with pyridoxine-dependent seizures (PDS) were seen over a period of 10 years. Of those children, 6 are on regular follow-up. Four of the children were seen in one family. All the patients presented with refractory seizures, mainly neonatal status epilepticus. Though PDS is a rare condition, it must be considered in all cases with refractory seizures, particularly in children youn...
