Training in Skull Base Endonasal Endoscopic Surgery: Development and Validation of a Novel Low-Cost Simulation with Animal Cadaveric Model.

Background: Endoscopic skull base surgery is constantly evolving and its scope has expanded. The acquisition of surgical skills involves a long learning curve with significant risks for the patient. Therefore, training in the laboratory has become essential to achieve appropriate proficiency and reduce the morbidity and mortality associated with these procedures.

Intracranial video-EEG and surgery for focal atonic seizures.

Atonic seizures are epileptic attacks characterised by a sudden loss or diminution of muscle tone. Structures corresponding to inhibitory cortical areas, such as the primary negative motor area or the supplementary negative motor area, could be responsible. We present findings observed in a patient with atonic seizures due to focal epilepsy, who underwent intracranial video-EEG monitoring and epilepsy surgery, and discuss possible underlying mechanisms.

Epilepsy surgery in Argentina: long-term results in a comprehensive epilepsy centre.

Rationale: Epilepsy surgery procedures started in Argentina more than 50 years ago. This is the first comprehensive and systematic survey of epilepsy surgery long-term outcome from our country.

Methods: A descriptive cohort study was conducted between 1998 and 2008 for drug-resistant epilepsy surgery with a minimum of 12 months follow-up (n=110).
