[Neuropsychological profile of Mexican paediatric patients with pharmacoresistant focal epilepsy]. / Perfil neuropsicológico de pacientes pediátricos mexicanos con epilepsia focal farmacorresistente.

INTRODUCTION: At least 20% of paediatric patients with epilepsy present resistance to multiple anti-crisis drugs in trials, which has a negative impact on their neuropsychological state, quality of life and prognosis; it is therefore necessary to document their neuropsychological profile in order to improve the clinical approach to them. AIMS: To describe the neuropsychological profile (cognitive, academic, behavioural, emotional, adaptive, sleep disturbances and quality of life) of paediatric patients with drug-resistant focal epilepsy in the frontal, temporal and occipital lobes, and to compare performance between patients with frontal and temporal foci, and to assess the link between the duration of the condition, the frequency of seizures and the amount of anti-crisis drugs and the neuropsychological profile. PATIENTS AND METHODS: The neuropsychological profile of 19 paediatric patients with a diagnosis of pharmacoresistant epilepsy with a mean age of 10.89 years was evaluated. RESULTS: 57.9% of the 19 patients were men. 63.2% presented frontal focus; 26.3% presented temporal focus; and 10.5% presented occipital focus. Deficiencies in attention, comprehension, verbal memory, working memory and processing speed, in addition to adaptive difficulties were observed. When the patients with frontal and temporal focus were compared, the former were found to present greater deficits in planning, while the patients with temporal focus presented more severe symptoms of anxiety. Patients with a longer disease duration were found to present greater impairment to their intelligence quotient and adaptive behavioural skills. CONCLUSIONS: Pharmacoresistant epilepsy in paediatric patients affects intelligence quotient and adaptive skills, as well as attention, memory and executive functions, and neuropsychological intervention programmes must therefore be implemented to improve these patients' quality of life.

TITLE: Perfil neuropsicológico de pacientes pediátricos mexicanos con epilepsia focal farmacorresistente.Introducción. Al menos el 20% de los pacientes pediátricos con epilepsia muestra resistencia a los ensayos de múltiples fármacos anticrisis, que impactan negativamente en su estado neuropsicológico, calidad de vida y pronóstico; por tal motivo, es necesario documentar ampliamente su perfil neuropsicológico para mejorar su abordaje clínico. Objetivos. Describir el perfil neuropsicológico (cognitivo, académico, conductual, emocional, adaptativo, alteraciones del sueño y calidad de vida) de pacientes pediátricos con epilepsia focal farmacorresistente de los lóbulos frontal, temporal y occipital, así como comparar el desempeño entre los pacientes con foco frontal y temporal, y evaluar la asociación entre la duración del padecimiento, la frecuencia de las crisis y la cantidad de fármacos anticrisis con el perfil neuropsicológico. Pacientes y métodos. Se evaluó el perfil neuropsicológico de 19 pacientes pediátricos con diagnóstico de epilepsia farmacorresistente, con una edad promedio de 10,89 años. Resultados. De los 19 pacientes, el 57,9% fueron hombres. El 63,2% presentó foco frontal; el 26,3%, temporal; y el 10,5%, occipital. Se encontraron deficiencias en atención, comprensión, memoria verbal, memoria de trabajo y velocidad de procesamiento, además de dificultades adaptativas. Al comparar a los pacientes con foco frontal y temporal, se encontró que los primeros presentaron mayores deficiencias en planificación, mientras que los pacientes con foco temporal presentaron mayores síntomas de ansiedad. Con respecto a la duración de la enfermedad, se encontró que los pacientes con mayor duración del padecimiento presentaron mayor afectación en el cociente intelectual y en las habilidades en la conducta adaptativa. Conclusiones. La epilepsia farmacorresistente en pacientes pediátricos afecta el cociente intelectual y las habilidades adaptativas, así como a la atención, la memoria y las funciones ejecutivas, por lo que es necesaria la implementación de programas de intervención neuropsicológica para mejorar la calidad de vida de estos pacientes.

[A comparative study of Rashkind, Grifka and coil devices in percutaneous closing of patent ductus arteriosus]. / Estudio comparativo entre dispositivos de Rashkind, Grifka y Coil para el cierre percutáneo del conducto arterioso.

This study was performed to evaluate the efficacy of transcatheter Coil and Grifka closure of the patent ductus arteriosus in comparison to our experience with the Rashkind umbrella device. Ninety seven patients (36 male and 61 females) underwent occlusion of the PDA. The following variables were compared: age, sex, ductus diameter, morphology, device, occlusion time, residual shunt, multiple device and complications. Data obtained were compared using the Student's test and Chi 2. Median patient age was 7.82 +/- 6.89, forty five patients underwent transcatheter Rashkind-17 closure, 19 patients with Rashkind-12, 18 patients with Coil and 13 patients with Grifka device, in two patients the closure could not be performed. There were differences between the morphology and device used (p = 0.008), between the ductus diameter and device used (p < 0.001). There was immediate closure in 26.7% in the Rashkind-17 group compared with, 57.9% for the Rashkind-12 group, 83.3% for Coil group and of 91.7% for Grifka group. The occlusion within 24 hrs of implantation was 60% with Rashkind-17, 78.9% with Rashkind-12, 94.4% with Coil and 100% with Grifka. Residual shunt persisted for more than a year in 7 patients with Rashkind-17 and 1 with Rashkind 12, (p = 0.001), in 4 patients two devices wore placed. The complications were, 15.5% for Rashkind-17, 26.3% for Rashkind-12, 5.2% for Coil and 30% for Grifka, (p = 0.004), one coil and one Grifka embolized. Transcatheter Coil and Grifka occlusion are more effective in achieving immediate closure than the Rashkind device. The indication to use each device is made according to the morphology and size of the ductus.
