Neuroendoscopy for Intracranial Arachnoid Cysts in Infants: Therapeutic Considerations.

Background The use of the endoscope for various cranial procedures is gradually expanding. Intracranial cystic lesions in the brain are one of the most attractive targets for this minimally invasive procedure, thus avoiding conventional craniotomy. These cystic lesions in the brain, namely arachnoid cysts, are congenital.

Role of MDR1 C3435T and GABRG2 C588T gene polymorphisms in seizure occurrence and MDR1 effect on anti-epileptic drug (phenytoin) absorption.

Aims: To assess the role of MDR1 and gamma-aminobutyric acid receptor-gamma 2 sub unit (GABRG2) gene polymorphism in seizure susceptibility in generalized seizure (GS) and febrile seizure (FS) patients and to evaluate MDR1 C3435T gene polymorphism's role in absorption of the anti-epileptic drug, phenytoin (PHT) in a cohort of patients.

Methods: One hundred twenty-seven cases of seizure (86 GS and 41 FS) patients were analyzed for MDR1 C3435T and GABRG2 C588T gene polymorphisms using restriction fragment length polymorphism-polymerase chain reaction. Serum PHT levels were analyzed.
