RESUMO

Introducción. La cirugía de la epilepsia podría ser una opción terapéutica muy prometedora para el control de las crisis en pacientes con crisis refractarias que no responden a la medicación. Otro factor importante a favor de la opción quirúrgica son los resultados cognitivos. Objetivo. Investigar la correlación entre los resultados tanto de las crisis como cognitivos tras la cirugía para tratar la epilepsiaen una población pediátrica.Pacientes y métodos. Se evaluó de manera retrospectiva a un total de 59 pacientes pediátricos antes y al menos seis meses después de la cirugía mediante la tercera edición de la escala de inteligencia para niños de Wechsler (escala global, escala verbal y escala manipulativa). Se dividió a los pacientes en dos grupos en función de la presencia o ausencia de la mejoría del control de las crisis tras la cirugía. Los datos que se recogían de cada niño incluían: tipo de epilepsia, etiología, edad de comienzo de la epilepsia, duración de la epilepsia y frecuencia de las crisis.Resultados. Al comparar los datos mediante un análisis multivariado de la varianza se observaron diferencias significativas en las escalas global, verbal y manipulativa preoperatorias (p = 0,01) con unos resultados mejores en el grupo con reducción de las crisis que en el grupo sin reducción de las crisis. El grupo con mejoría de las crisis consiguió una mejoría significativa en la escala manipulativa (p = 0,01) y el grupo sin mejoría de las crisis obtuvo un empeoramiento significativoen la escala verbal (p = 0,01).Conclusiones. Nuestros resultados sugieren que el éxito de la cirugía para el tratamiento de la epilepsia en la infancia cuando se logra un control de las crisis podría conllevar también una mejoría en la escala manipulativa, mientras que lapersistencia de las crisis podría empeorar la escala verbal (AU)


Introduction. Epilepsy surgery may be a promising alternative therapy for seizure control in patients with refractory seizures, resistant to medication. Cognitive outcome is another important factor in favor of the surgical decision. Aim. To investigate the correlation between seizure outcome and cognitive outcome after epilepsy surgery in a pediatric population. Patients and methods. A total of 59 pediatric patients were retrospectively assessed with the WISC-III (Full Scale, Verbal Scale and Performance Scale) before and, at least, 6 months after surgery. Patients were divided into two groups according whether or not improvement of seizure control after surgery. Data collected for each child included: epileptic syndrome, etiology, age at epilepsy onset, duration of epilepsy and seizure frequency. Results. Comparison using a MANOVA test revealed significant differences across pre-operative Full Scale, Verbal Scale and Performance Scale (p = 0.01) with seizure reduction group performing better than no seizure reduction group. Seizureimprovement group achieved significant Performance Scale improvement (p = 0.01) and no seizure improvement groupshowed significant Verbal Scale worsened after surgery (p = 0.01).Conclusions. Our results suggest that the success of the epilepsy surgery in childhood when the seizure control is achieved may also provide an improvement in the Performance Scale whereas the seizure maintenance may worsen the Verbal Scale (AU)

RESUMO

OBJECTIVES: Although chronic calcified neurocysticercosis (NCC) has been considered a major cause of symptomatic epilepsy in developing countries, it can also be an incidental pathological finding in epileptic patients from endemic regions. The mechanisms of brain plasticity occurring in patients with NCC during and after the inflammatory process related to the parasite infection, death, degeneration, and calcification within the host brain might be an independent factor for cognitive impairment in patients with NCC and epilepsy. In order to assess this possibility cognitive performance of patients with mesial temporal lobe epilepsy related to hippocampal sclerosis (MTLE-HS) with and without NCC was investigated through structured neuropsychological testing. METHODS: Cognitive performance of long term MTLE-HS patients with (HS-NCC group, n = 32) and without NCC (HS only, n = 48) was compared. Imbalances between the two groups with respect to clinical, demographic, neuroimaging, and electrophysiological variables were adjusted by linear multiple regression analysis and Bonferroni correction for multiple tests. RESULTS AND CONCLUSIONS: There were no cognitive performance differences between HS-NCC and HS only patients, leading to the conclusion that chronic calcified NCC per se does not aggravate the cognitive performance of patients with long term MTLE-HS.
