ABSTRACT
ABSTRACT Background: self-limited epilepsy with centrotemporal spikes, previously considered benign focal childhood epilepsy with centrotemporal spikes show clinical signs of involvement of Rolandic areas, mainly lower area, which may affect the planning and execution of motor sequences. Objective: This study aimed to evaluated oral praxis in children with self-limited epilepsy with centrotemporal spikes and compare to the age-matched control group. Methods: This was a descriptive study with 74 children with self-limited epilepsy with centrotemporal spikes, with the classical forms according to International League Against Epilepsy, and between 4 and 15 years of age, selected from the child neurology outpatient clinic of the Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo, São Paulo, Brazil, and 239 age-matched and educational level-matched (convenience sampling) control children. All children were submitted to the battery of oral volitional movements, which consisted of 44 tests for oral movement (tongue, lip, cheek, jaw, and palate) and 34 phonemes and consonant cluster tasks, with simple and sequenced oral movements. Results: The mean age and standard deviation (SD) of children with epilepsy was 9.08 years (SD 2.55) and of controls 9.61 years (SD 3.12). The results showed significant differences between the groups with a poorer performance of children with epilepsy compared to children without epilepsy in simple and particularly in sequenced movements. Conclusion: These findings can be attributed to the genetically determined immaturity of cortical structures related to motor planning in children with self-limited epilepsy with centrotemporal spikes.
RESUMO Antecedentes: Epilepsia autolimitada com descarga centrotemporal, previamente designada por epilepsia benigna focal infantil com espículas centrotemporais, mostra sinais clínicos de envolvimento de áreas rolândicas, principalmente área inferior, que podem afetar o planejamento e a execução de sequências motoras. Objetivo: Este estudo visou avaliar a práxis oral em crianças com epilepsia autolimitada com espículas centrotemporais e comparar com o grupo de controle de mesma idade e grau de escolaridade. Métodos: Tratou-se de um estudo descritivo, com 74 crianças com epilepsia autolimitada com espículas centrotemporais selecionadas no ambulatório de neurologia infantil do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, São Paulo, Brasil, e 239 crianças do grupo controle da mesma faixa etária e grau de escolaridade. Todas as crianças foram submetidas à bateria de tarefas de movimento oral volitivo, que inclui movimentos orais simples e sequenciados. Resultados: A idade média das crianças com epilepsia era de 9,08 anos (desvio padrão - DP 2,55) e dos controles 9,61 anos (DP 3,12). Os resultados mostraram diferenças significativas entre os grupos, com desempenho mais fraco das crianças com epilepsia em comparação ao das crianças saudáveis, em movimentos simples e particularmente em movimentos sequenciados. Conclusão: Esses resultados podem ser atribuídos à imaturidade geneticamente determinada das estruturas corticais relacionadas com o planejamento motor em crianças com epilepsia autolimitada com espículas centrotemporais.

INTRODUCTION: Continuous spikes and waves during slow sleep (CSWS) is an EEG pattern that appears during childhood, and is often associated with cognitive impairment. It can appear in the course of epileptic syndromes, as well as in benign epilepsy. The aim of this study is to analyse epidemiological and clinical characteristic of patients with CSWS, in order to describe possible predictive factors in their outcome. METHODS: A retrospective study was conducted on paediatric patients with CSWS treated in a third-level hospital from November 1997 to November 2017. RESULTS: The study included 25 patients (68% male), of whom 76% had abnormalities in the neuroimaging or suffered from psychomotor development disorder (secondary CSWS). The rest were healthy, or diagnosed with idiopathic epilepsy. The mean age of onset of CSWS was 6.7 years, but earlier in the secondary CSWS cases. Symptoms were present during the CSWS episode in 72% of cases. All of them were treated with antiepileptic drugs, which were effective in 36%. CSWS stopped in 72%, and remission was longer if the CSWS onset occurred at an older age. One-third (33%) presented with sequelae, mostly cognitive and behavioural alterations. Outcome was poorer in those with secondary CSWS and, in those whose CSWS started at an earlier age and lasted longer. CONCLUSION: The CSWS pattern, although rare, is still a therapeutic challenge. A close follow-up of the patients with epilepsy is important, especially if associated with cognitive impairment, in order to establish an early diagnosis and treatment.

La epilepsia benigna con puntas centrotemporales o rolándicas se caracteriza por crisis parciales motoras en la infancia y un electroencefalograma en que observan descargas de puntas en las regiones centrotemporales medias. Ha sido reconocida como benigna, debido a la ausencia de déficits neurológicos evidentes; sin embargo, en los últimos años en la literatura médica internacional han aparecido varias publicaciones que cuestionan su evolución favorable. El objetivo de este trabajo es actualizar algunos criterios que no concuerdan con el buen pronóstico referido inicialmente. Representa una etapa fundamental en la historia de la epilepsia, debido a que es la primera vez que se describió una epilepsia focal o parcial en la que se presumía que no existía una lesión cortical subyacente.

Benign epilepsy with centrotemporal spikes, aka benign rolandic epilepsy, is characterized by partial motor crisis in childhood and electroencephalography showing point discharges in medial centrotemporal regions. The condition has been recognized as benign due to the absence of evident neurological deficits. However, in recent years several publications have appeared in international medical literature in which its favorable evolution is questioned. The objective of the present study is to update some criteria differing from the good prognosis initially stated. It constitutes a fundamental stage in the history of epilepsy, since for the first time a case of focal or partial epilepsy was being described in which presumably there did not exist an underlying cortical lesion. The evolution of this form of epilepsy may display features denying its benignity. It is recommended that in the future a study be conducted in our service confirming the criteria expounded in international medical literature(AU)

La Epilepsia Rolándica (ER) o Epilepsia con espigas centrotemporales, es la epilepsia idiopática más frecuente, focal autolimitada, de buena evolución. Debuta entre los 3 a 13 años, con crisis estereotipadas durante el sueño, al inicio o al despertar, focales motoras y somatosensoriales. El electroencefalograma (EEG) muestra una base normal con actividad epileptiforme interictal centrotemporal, con espigas con escaso desarrollo de onda lenta, uni o bilaterales. Se describe en los últimos años una forma atípica de ER (ERA), asociando otros tipos de crisis, que responden peor a tratamiento, manteniendo crisis, con complicaciones neuropsicológicas asociadas y deterioro del EEG, observándose en algunos casos, actividad, continua o casi continua en sueño. El objetivo de este trabajo es caracterizar a los pacientes con ER que se controlan en Red Salud UC-Christus y describir la presencia de posibles factores de riesgo asociados a la evolución atípica de la ER. 16 pacientes con ER típica y otros 6 con ERA, ambos grupos edad promedio 6 años al debut presentación, de predominio sexo masculino, la mayoría con buen rendimiento escolar y examen neurológico normal. En ER, crisis de predominio focales y base de EEG 62% normal. EEG entre ocasional y muy frecuentes descargas epileptiformes. En ERA, solo un 33% base normal, y predominio crisis generalizadas. Mayoría evoluciona con descargas EEG contínuas o casi continuas en sueño No-REM. Hubo peor respuesta a FAEs en ERA. Concluimos que este estudio es concordante con lo descrito en la literatura actual para pacientes con ER y ERA, por lo que recomendamos considerar la presencia de posibles factores indicadores, iniciales o durante la evolución, de formas atípicas de ER.

Abstract: Rolandic Epilepsy (ER) or epilepsy with centrotemporal spikes, is a focal and selflimited epilepsy and it is the most frequent and well-recognized idiopathic epilepsy. It is characterized by an age of presentation between 3 and 13 years, with stereotyped seizures during sleep, at the beginning or on awakening, which can be focal, motor and sensory. The electroencephalogram shows a normal base with interictal epileptiform activity, centrotemporal spikes with poor slow wave development, which can be unilateral o bilateral. In recent years, an atypical presentation of Rolandic Epilepsy (ERA) has been described, with presence of other types of seizures, with poor response to treatment, continued seizures and asso- ciated neuropsychological complications and deterioration of the electroencephalogram, in some cases with continuous or almost continuous activity during sleep. Our work aims to characterize the patients that are controlled in the Red Salud UC-Christus and to describe the presence of possible risk factors associated with the atypical evolution of Rolandic Epilepsy. We studied 16 patients with typical ER and other 6 with ERA, both groups with an age average of 6 years at time of debut presentation, more frequent in males, most with good school performance and normal neurological examination. In ER there were focal prevalence seizures and 62% had an EEG with a normal base. The EEG showed occasional to very frequent epileptiform discharges. In ERA, only 33% of the EEG had a normal base, and it most frequently showed generalized seizure. Most of the patients followed up with continuous or nearly continuous discharges in the EEG during REM sleep. There was worse response to FAEs in ERA. We conclude that this study is consistent with that described in the current literature for patients with ER and ERA, we recommend physicians to consider the presence of possible initial of belated indicators of atypical forms of ER.Key words: Rolandic Epilepsy, atypical Rolandic Epilepsy, risk factors of atypical evolution, centrotemporal spikes, focal seizures.
ABSTRACT
This study investigated how the difficulties in language in children with Rolandic Epilepsy (RE) could be related to alterations in their development of phonological awareness and/or working memory. We evaluated fourty-two children aged 6 to 13 years old. From these, twenty-one children were diagnosed with RE and formed the experimental group; and twenty-one children without RE, paired with the experimental group by sex, age, education and socioeconomic status, formed the control group. The results showed significant differences in the performances of children with RE and healthy children in the tests that evaluated working memory and phonological awareness. Also, positive and high significant correlations were found between working memory and phonological awareness in the RE clinical subgroup. Generally, the results suggest that compromises in both cognitive functions might be associated to loss of language capabilities in children with RE, and also point that the development of working memory and phonological awareness are interconnected.
En este estudio se investigó cómo las dificultades en el lenguaje en niños con epilepsia Rolandica (ER) podrían estar relacionadas con alteraciones en su desarrollo de la conciencia fonológica y/o memoria de trabajo. Se evaluaron 42 niños de 6 a 13 años de edad. De éstos, 21 niños fueron diagnosticados con ER y formaron el grupo experimental; y 21 niños sin RE, emparejados con el grupo experimental por sexo, edad, nivel educativo y socioeconómico, que formaron el grupo de control. Los resultados mostraron diferencias significativas en los resultados de los niños con ER y niños sanos en las pruebas que evaluaron la memoria de trabajo y la conciencia fonológica. Además, se encontraron correlaciones positivas y altas entre la memoria de trabajo y la conciencia fonológica en el subgrupo clínico RE. En general, los resultados sugieren que los compromisos en ambas funciones cognitivas pueden estar asociados a la pérdida de capacidades del lenguaje en los niños con RE, y también señalan que el desarrollo de la memoria de trabajo y la conciencia fonológica están interconectados.
ABSTRACT
Objective Although benign epilepsy with centrotemporal spikes (BECTS) is an idiopathic, age-related epilepsy syndrome with favorable outcome, recent studies have shown impairment in specific neuropsychological tests. The objective of this study was to analyze the comorbidity between dyslexia and BECTS. Method Thirty-one patients with clinical and electroencephalographic diagnosis of BECTS (group A) and 31 paired children (group B) underwent a language and neuropsychological assessment performed with several standardized protocols. Our findings were categorized as: a) dyslexia; b) other difficulties; c) without difficulties. Our results were compared and statistically analyzed. Results Our data showed that dyslexia occurred in 19.4% and other difficulties in 74.2% of our patients. This was highly significant when compared with the control group (p<0.001). Phonological awareness, writing, reading, arithmetic, and memory tests showed a statistically significant difference when comparing both groups. Conclusion Our findings show significant evidence of the occurrence of dyslexia in patients with BECTS. .
Objetivo Apesar da epilepsia benigna da infância com espículas centrotemporais (EBICT) ser uma síndrome epiléptica considerada idiopática, idade-relacionada e de evolução favorável, estudos recentes têm mostrado que essas crianças apresentam prejuízo em testes neuropsicológicos específicos. O objetivo desse estudo foi analisar a comorbidade entre EBICT e dislexia. Método Trinta e um pacientes com diagnóstico clínico e eletrencefalográfico de EBICT (grupo A) e 31 crianças pareadas (grupo B) foram submetidos à avaliação neuropsicológica e de linguagem com vários protocolos estandardizados. Nossos achados foram categorizados em: a) dislexia; b) outras dificuldades; c) sem dificuldades. Nossos resultados foram comparados e analisados estatisticamente. Resultados Os dados mostraram que dislexia ocorreu em 19,4% e outras dificuldades em 74,2% dos nossos pacientes. Esses números foram altamente significativos quando comparados com o grupo controle (p<0,001). Consciência fonológica, leitura, escrita, aritmética e testes de memória mostraram diferença estatisticamente significante quando foram comparados os dois grupos. Conclusão Nossos dados mostraram que há evidência da ocorrência de dislexia em pacientes com EBICT. .

Introdução: Uma importante aplicação da técnica de Ressonância Magnética funcional é em pesquisa clínica, acerca das funções cognitivas de pacientes, como por exemplo atenção, memória, linguagem, dentre outras. Pacientes com Epilepsia Idiopática da Infância podem apresentar déficits cognitivos e não possuem alterações estruturais detectáveis o que facilita a aplicação de técnicas computacionais de registro e normalização em estudos de neuroimagem o que possibilita a geração de imagens de um grupo de indivíduos e suas diversas possibilidades de inferências estatísticas. Este estudo teve como objetivo descrever as funções cognitivas em pacientes com Epilespia Rolândica (ER) e Epilepsia de Ausência (EA) através da RMf. Métodos: 57 indíviduos, 23 pacientes com ER ((média= 10,7 anos), 20 pacientes com EA (média= 9,9 anos) e 14 controles saudáveis (média=10 anos) foram submetidos ao vídeo-EEg, testes neuropsicológicos para avaliação das funções cognitivas (QI, funções executivas, dentre outras) e um paradigma de atenção Stoptask Gonogo e um paradigma Resting State (RS). Os dados foram analisados e foram gerados mapas limirializados de ativação da função BOLD. Resultados: As principais áreas ativas em pacientes e controles no paradigma Stoptask foram: hemisférios cerebelares bilateral, córtex orbito frontal bilateral, giros fusiformes, ínsula bilateral, córtex dorso latero pré-frontal, giro do Cíngulo anterior direito e esquerdo, bordas dos sulcos intraparietais, giros frontais superiores, eye-field.(p < 0,01). No paradigma RS as áreas encontradas foram: Córtex medial prefrontal, giro angular, giro supramarginal, giro do cíngulo posterior, giro frontal superior, sulco intraparietal, área motora suplementar, córtex prefrontal lateral (p < 0,05). OS mapas comparativos de grupos mostraram diferenças em ativaçao entre pacientes e controles. Discussão: Nossos mapas de ativação da resposta BOLD são semelhantes aos encontrados por outros autores na...
Introduction: An important application of functional MRI is in clinical research about the cognitive functions of patients, such as attention, memory, language, among others. Patients with Idiopathic Epilepsy of Childhood may show cognitive deficits and have no detectable structural changes which facilitates the application of computational techniques and standardization of registration in neuroimaging studies, which enables to obtain a group map of individuals and their various possibilities for statistical inferences. This study aimed to describe the cognitive functions in patients with Rolandic Epilepsy (RE) and absence epilepsy (AE) by fMRI. Methods: 57 individuals, 23 patients with RE (mean = 10.7 years), 20 patients with AE (mean = 9.9 years) and 14 healthy controls (mean = 10 years) underwent video-EEG, neuropsychological tests for assessment of cognitive function (IQ, executive functions, amongothers) theu also perform an attention paradigm Stoptask Gonogo and the Resting State (RS). Data were analyzed and maps were generated for BOLD activation function. Results: The main areas active in patients and controls in the paradigm Stoptask were bilateral cerebellar hemispheres, bilateral frontal orbital cortex, fusiform gyrus, bilateral insula, dorsal lateral prefrontal cortex, anterior cingulate gyrus right and left edges of the intraparietal sulcus, superior frontal gyrus, eye -field. (p < 0.01). In the RS paradigm areas observed were: medial prefrontal cortex, angular gyrus, supramarginal gyrus, posterior cingulate gyrus, superior frontal gyrus, intraparietal sulcus, supplementary motor area, lateral prefrontal cortex (p < 0.05). there were no statistically significant differences between group means (p < 0,01)Discussion: Our activation maps of BOLD response are similar to those found by other authors in the literature both in Stoptask paradigm as in the RS. The diferences between groups may be due cognitive deficts in patients group. Conclusions:...

This study evaluated the sequential motor manual actions in children with benign focal epilepsy of childhood with centrotemporal spikes (BECTS) and compares the results with matched control group, through the application of Luria's fist-edge-palm test. The children with BECTS underwent interictal single photon emission computed tomography (SPECT) and School Performance Test (SPT). Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.

OBJECTIVES: To evaluate the presence of neurological soft signs (NSS) and to correlate them with the Wechsler Intelligence Scale for Children (WISC III) in patients with rolandic epilepsy (RE). METHODS: Forty children and adolescents aged between 9 and 15 years were studied. They were divided into two groups: G1 - patients with RE (n=20) - and G2 - healthy controls without epilepsy (n=20). They were assessed with the Quick Neurological Screening Test (QNST II) - clinical trial to search for NSS -, and the WISC III - neuropsychological test. RESULTS: No statistical difference between groups was found in WISC III and QNST II. However, children with poorer motor skills had worse performance in the QNST II and also in the execution intelligence quotient - IQ (p=0.001) and in total IQ (p=0.004), thus showing a positive correlation between them. CONCLUSIONS: The QNST II is a good screening tool for the neurologist to detect abnormalities in fine motor skills.
OBJETIVOS: Avaliar a presença de sinais neurológicos menores (SNM) e correlacioná-los com o Escala de Inteligência de Wechsler para Crianças (WISC III) em pacientes com epilepsia rolândica (ER). MÉTODOS: Foram estudados 40 crianças ou adolescentes entre 9 e 15 anos, divididos em dois grupos: G1 - pacientes com ER (n=20); G2 - controles saudáveis sem epilepsia (n=20). Foram avaliados por meio do QNST II - teste clínico que pesquisa SNM - e do WISC III - teste neuropsicológico. RESULTADOS: Não foi encontrada nenhuma diferença estatística entre os grupos no WISC III e QNST II. Entretanto, crianças com habilidades motoras pobres tiveram pior desempenho no QNST II, assim como no quociente de inteligência (QI) de execução (p=0,001) e no QI total (p=0,004), mostrando, portanto, correlação positiva entre os dois instrumentos. CONCLUSÕES: O QNST II é uma boa ferramenta de rastreamento para o neurologista detectar anormalidades nas habilidades motoras finas.

Objetivo: Describir la presencia de alteraciones de la actividad de base a través del análisis cuantitativo del EEG (QEEG) en pacientes portadores de Epilepsia Rolándica. Material y Método: Se realizó el análisis visual del EEG (29 pacientes) y el QEEG (26 pacientes). Los valores de poder absoluto y poder relativo obtenidos para cada paciente fueron comparados con una base de datos normativos mediante el estadígrafo transformada Z. Resultados: Se encontraron variaciones estadísticamente significativas de energía en 73,08 % de los casos: 73,68 % en las bandas lentas y 26,31 % para las rápidas. La topografía de la actividad lenta fue en regiones centro-temporales y/o centro-parietales 64,28 %, en las regiones anteriores y extratemporales 21,43 % y 14,28 % presentaron actividad lenta aislada extratemporal. Conclusiones: Las alteraciones significativas en la actividad de base electroencefalográfica antes descritas en los pacientes portadores de Epilepsia Rolándica, sugieren una posible relación con un disturbio maduracional o a la presencia de las descargas epileptiformes interictales.
Objective: To describe abnormalities of the background activity by quantitative analysis in patients with Rolandic Epilepsy. Methods: Visual (29 patients) and quantitative EEG (QEEG) (26 patients) analyses were done. Absolute and Relative Power values obtained in the patients were compared with those from a normative database (Z-Maps). Results: Q-EEG results showed a significative changes in a 73,08 % of the patients: 73,68 % in slow frequency and 26,31 % in rapid frequency. A focal significative increase in slow frequency in centro-temporal and/or centro-parietal regions was observed in 64,28 %, in the same regions and extratemporal regions in 21,43 % and only slow activity extratemporal in 14,28 % of the patients. Conclusions: Significative variations in background activity in patients with Rolandic Epilepsy, suggests a possible relation with the presence of interictal epileptiform discharges or a certain age-related functional immaturity.

A epilepsia rolândica (ER) corresponde de 15 a 25% de todas as epilepsias na infância antes do 15 anos de idade, caracterizada por crises parciais ou generalizadas, que ocorrem normalmente durante o sono ou durante o despertar. Sugere-se que a atividade epileptiforme eletrográfica possa causar deterioração cognitiva pela perturbação da formação das sinapses, assim como as drogas antiepilépticas, que podem ser uma das variáveis que corroboram um pior desempenho neuropsicológico. Apesar de normalmente não haver alterações no quociente intelectual global, essas crianças podem evoluir para dificuldades escolares, distúrbios de linguagem, funções executivas e coordenação motora. Esse artigo de revisão tem como propósito discutir diferentes achados na literatura acerca da evolução desse quadro clínico(AU)
Rolandic epilepsy (ER) corresponds to 15 - 25 percent of all childhood epilepsy prior to fifteen years of age, characterized by partial or generalized seizures, which typically occur during sleep or waking hours. It is suggested that the electrographic epileptiform activity may cause cognitive impairment by disturbing synopsis formation, as well as antiepileptic drugs, which may be one of the variables to corroborate a decrease in neuropsychological performance. In spite of the fact that typically, no changes are observed in the IQ; learning difficulties, language disorders, executive functions and a diminution in motor coordination are observed. This review purposes a discussion on the evolution of the clinical scenario(AU)
ABSTRACT
In the active phase of benign childhood epilepsy with centro-temporal spikes (BCECTS) there may be a fall in scholastic performance. OBJECTIVE: To study lexical decision in children with BCECTS. METHOD: 42 children with BCECTS were compared with a control group with respect to their hits and response time in a visual discrimination of words and pseudowords task (DWPT). RESULTS: The children with BCECTS had a lower percentage of hits for words and pseudowords and showed longer response times for pseudowords. They also frequently showed inferior reading and writing performance in the school performance test. The percentage of hits for pseudowords was lower when there was bilateral, asynchronous epileptiform activity. CONCLUSIONS: The DWPT provided contributions for reading assessments in children with BCECTS. The results indicated the need for attention in detecting reading difficulties in children with BCECTS.
Na fase ativa da epilepsia benigna da infância com pontas centrotemporais (EBICT) pode ocorrer queda de desempenho escolar. OBJETIVO: Estudar a decisão lexical em crianças com EBICT. MÉTODO: 42 crianças com EBICT foram comparadas a grupo controle quanto a acertos e tempo de resposta em tarefa de discriminação visual entre palavras e pseudopalavras (DVPPS). RESULTADOS: As crianças com EBICT tiveram percentual menor de acertos para palavras e pseudopalavras e maior tempo de resposta para pseudopalavras e tiveram, mais frequentemente, desempenho inferior em escrita e leitura em teste de desempenho escolar. Houve relação significativa entre os resultados do DVPPS e o teste de desempenho escolar. A percentagem de acerto de pseudopalavras foi menor quando havia atividade epileptiforme bilateral e assíncronia no eletrencefalograma. CONCLUSÃO: O DVPPS mostrou contribuições na avaliação da leitura em crianças com EBICT. Os resultados apontam para a necessidade de atenção na detecção de dificuldades de leitura em crianças com EBICT.

No existen estudios controlados, aleatorizados y con régimen de dosificación flexibles en niños con epilepsia rolándica, por lo que la terapia es aún empírica. Objetivo. Evaluar la eficacia y la tolerabilidad del clobazam (CLB) comparado con la carbamacepina (CBZ) en la epilepsia rolándica. Pacientes y métodos. Estudio prospectivo, abierto, controlado, aleatorizado de CBZ frente a CLB en niños con epilepsia rolándica con seguimiento durante dos años. Se aleatorizaron 45 pacientes y terminaron el estudio 38 sujetos. Se indicó un régimen de dosificación flexible. Se evaluó el control de crisis, el rendimiento escolar, el comportamiento, la adherencia al tratamiento, el grado de satisfacción de los padres y el perfil de efectos adversos. Resultados. Ambos medicamentos fueron igualmente eficaces para controlar las crisis (el 94,1por ciento de pacientes con CLB y el 100 por ciento con CBZ estaban libres de crisis al finalizar el estudio; p = 0,26). El CLB logró controlar las crisis más tempranamente (33,3 ± 45 frente a 48,2 ± 72,3 días; p < 0,05) y tuvo menos efectos adversos que la CBZ (aparecieron efectos adversos en tres pacientes con CLB y ocho con CBZ; p = 0). En dos pacientes en régimen de CBZ, las crisis empeoraron y junto con ello aparecieron complicaciones cognitivoconductuales. La CBZ es un medicamento eficaz en la epilepsia rolándica, pero puede asociarse a un empeoramiento de las crisis, así como a déficit cognitivos y conductuales. El CLB en monoterapia parece ser un fármaco eficaz y mejor tolerado en este tipo de epilepsia(AU)
To date no controlled, randomised studies with flexible dose regimens have been conducted in children with rolandic epilepsy, and therapy is therefore still empirical.To evaluate the effectiveness and safety of clobazam (CLB) compared with that of carbamazepine (CBZ) in rolandic epilepsy. A prospective, open, controlled and randomised study was carried out to compare CBZ and CLB in children with rolandic epilepsy with a follow-up over a two-year period. A random sample of 45 patients was taken and 38 of them finished the study. A flexible dose regimen was indicated. Control of seizures, academic performance, behaviour, adherence to treatment, parents' degree of satisfaction and side effect profiles were all evaluated. Both drugs were equally effective at controlling seizures (94.1 percent of patients with CLB and 100 percent of those with CBZ were free of seizures on ending the study; p = 0.26). CLB controlled seizures earlier (33.3 +/- 45 days versus 48.2 +/- 72.3; p < 0.05) and had fewer side effects than CBZ (side effects appeared in three patients with CLB and in eight of those on CBZ; p = 0). In two of the patients taking CBZ, the seizures got worse and a series of cognitive-behavioural complications also appeared. CBZ is an effective drug in rolandic epilepsy, but it may be associated with exacerbation of seizures as well as with cognitive-behavioural impairment. CLB in monotherapy seems to be an effective and better tolerated drug in this kind of epilepsy(AU)

Objetivo. Describir los resultados obtenidos con el mapeo cortical intraoperatorio en el tratamiento de los tumores rolándicos. Método. El estudio se realizó en 27 pacientes (mayo 2000 - mayo 2005) entre 27 y 78 años (16M-11F) con tumores intracraneanos ubicados en el área central. En todos los casos se efectuaron técnicas de localización funcional y se utilizaron potenciales evocados somatosensitivos intraoperatorios y estimulación cortical bipolar. Resultados. La resección fue total en 24 casos y subtotal en 3 casos. En los 23 pacientes que presentaban algún déficit motor previo a la cirugía se logró la mejoría en 17 de ellos, permaneciendo estables 5 y sólo 1 caso padeció un empeoramiento transitorio. Ningún paciente sin déficit previo lo padeció después. No se registraron complicaciones relacionadas con el procedimiento de localización. Conclusión. El mapeo cortical intraoperatorio es una técnica segura y confiable para la preservación de la corteza elocuente en la cirugía de tumores del área rolándica.
Objective: To describe the results obtained with intraoperative cortical mapping in the surgical treatment of rolandic tumors. Method: We studied 27 patients (may 2000-may 2005) between 27 and 78 years old (16 males-11 females) with intracranial tumors located in the rolandic area. In all cases we used techniques of functional localization and, intraoperative somatosensorial evoked potentials and bipolar cortical stimulation. Results: In 24 cases removal was total and in 3 cases was subtotal. Of the 23 cases with preoperative motor symptoms, postoperatively 17 were improved, 5 remained stable and 1 deteriorated transiently. No patient without preoperative deficits was worst. We did not have complications related to the localization procedure. Conclusion: Intraoperative cortical mapping is a safe and sound technique for the preservation of the eloquent cortex during surgery of rolandic tumors.

Las epilepsias focales idiopáticas de la infancia constituyen el 30-35 por ciento de todas las epilepsias en el rango de edad de 2 a 10 años. La más frecuente de todas es la epilepsia benigna de la infancia con espigas centrotemporales, denominada también Rolándica. En segundo lugar se encuentran las epilepsias occipitales que, aunque son relativamente infrecuentes, se deben conocer para hacer el diagnóstico y diferenciarlas de otras entidades más frecuentes como la migraña con aura.Entre las epilepsias occipitales se deben diferenciar las formas "sintomáticas" (que tienen causas conocidas) de las idiopáticas (genéticas). En las primeras se logra demostrar una lesión estructural en el sistema nervioso central (SNC) que puede explicar la epilepsia. Las epilepsias idiopáticas occipitales benignas de la infancia se dividen de acuerdo con la edad de inicio, el cual puede ser temprano, conocida también como tipo Panayiotopoulos, o tardío, también denominada tipo Gastaut. Hay una tercera forma de epilepsia idiopática aún no aceptada por muchos autores, la cual es una combinación de las dos anteriores, con un patrón electroencefalográfico específico. La migraña con aura presenta algunas características que permiten al clínico diferenciarla de las epilepsias occipitales.
