Although rare in childhood, stroke may have a serious impact when it happens in this stage of life. Also, it may be the first sign of a systemic disease. We report 12 cases of patients with stroke treated in the Neuropediatrics Unit of Hospital de Clínicas de Porto Alegre (HCPA) from March 1997 to March 2000. All patients, from term infants to 12-year-old children hospitalized in the Pediatrics Unit of HCPA, had clinical suspicion of stroke, which was later confirmed by radiological studies. Patient follow up ranged from 1 to 6 years (mean = 3.4 years). Presenting symptoms were hemiparesis in 9 patients, seizures in 7, deviation of labial commissure in 3, and loss of consciousness in 1. The increase in the number of cases of childhood stroke identified and later confirmed by noninvasive methods had helped in the determination of different ethiologies of stroke: the most frequent being hematologic, cardiac and genetic diseases. However, our study included 6 newborns with stroke whose ethiology was not identified. Seven children with seizures received phenobarbital. Six term infants had neonatal seizures secondary to stroke and restricted to the first 72 hours of life.

The evolution of autism symptoms during life were revised, from childhood to adulthood. Little information is available. After a search in PubMed, no more than 40 publications address this issue. The review was divided into two parts: a) how change the three main symptoms of autism change; b) how change the other autism-associated symptoms. The three main symptoms, called “Triad of Wing” (communication problems, social skills deficits, and a restricted repertoire of interests) do not change significantly during lifetime. The diagnosis of autism remains stable during lifetime, and 80% of children continue with this diagnosis in adulthood. Furthermore, it is difficult to establish first diagnostic of autism in adults. In relation to the associated symptoms, one of the earliest are sleep disturbances and one of the most prevalent is both bipolar and anxiety disorders. Sleep disturbances are age-limited and disappear easily. Bipolar disorders are usually more severe in children with autism when compared to children without autism. The mood transitions are faster in autistic children. Anxiety is usually more intense in cognitive preserved autistic patients and tends to increase with age. The two main prognostic factors for autism in adults are: a) total IQ above 70. b) functional language before 6 years of age. Se ha revisado la evolución de los síntomas del autismo durante la vida, desde la niñez hasta la edad adulta. Hay poca información disponible. Después de una búsqueda en PubMed, no más de 40 publicaciones abordan específicamente este tema. La revisión fue dividida en dos partes: a) cómo cambian los tres principales síntomas del autismo; b) cómo cambian los demás síntomas asociados al autismo. Los tres síntomas, llamados la “Tríada de Wing” (problemas en la comunicación, déficits en las habilidades sociales, y un restringido repertorio de intereses) no cambian significativamente con el pasar de la vida. El diagnóstico de autismo se mantiene estable en el tiempo, ya que 80% de los niños continúan con el diagnóstico en la vida adulta. Por otro lado, es difícil establecer este diagnóstico por primera vez en los adultos. En relación a los síntomas asociados, los más precoces son los trastornos del sueño y de los más prevalentes los trastornos bipolares y también el trastorno de ansiedad. Los trastornos del sueño son edad-limitados y desaparecen fácilmente. Los trastornos bipolares suelen ser más graves en niños con autismo cuando se comparan con niños sin autismo. Las variaciones del estado de ánimo son más rápidas en niños autistas. La ansiedad suele ser más intensa en los autistas con preservación cognitiva y tiende a aumentar con la edad. Los dos principales factores pronósticos para el autismo en adultos son: a) cociente intelectual total superior a 70; b) lenguaje funcional antes de los 6 años de edad.

OBJETIVO: avaliar o efeito do tipo de parto e dos procedimentos obstétricos usuais sobre o estado neurológico das primeiras 48 horas de vida, em uma amostra de recém-nascidos consecutivos a termo e saudáveis, usando um sistema de escores (NACS - Neurologic Adaptative Capacity Score). MÉTODOS: coorte prospectiva com 313 recém-nascidos de uma Unidade de Neonatologia e Alojamento Conjunto. As variáveis analisadas foram as obstétricas; o desfecho clínico - fase de baixo vigor neurológico, avaliada pelo NACS com 4, 24 e 48 horas de vida. Foram realizadas duas avaliações dos dados: uma com toda a amostra e outra comparando o Grupo Vigoroso, cujos recém-nascidos mantiveram-se com 35 ou mais pontos no NACS, versus Grupo de Baixo Vigor com menos de 35 pontos durante as três avaliações consecutivas. Foram realizadas análises bivariadas e multivariadas. Foram buscadas possíveis associações entre a fase de baixo vigor neurológico e o tipo de parto, bem como entre a fase de baixo vigor neurológico e as variáveis obstétricas. RESULTADOS: na análise bivariada, o tipo de parto e as variáveis obstétricas não estiveram associados com a fase de baixo vigor neurológico. Entretanto, a associação entre o aspecto do líquido amniótico e a fase de baixo vigor neurológico atingiu valores bem próximos da significância e, então, foi incluído na análise multivariada. Na análise multivariada, a única variável associada com baixo vigor neurológico foi a presença de líquido amniótico tinto de mecônio, que mostrou 8,1 vezes maior risco de baixa pontuação neurológica quando comparados o Grupo Vigoroso e o Grupo de Baixo Vigor. Na análise da amostra global, o mesmo risco foi de 1,7. CONCLUSÕES: nem o tipo de parto nem as manobras obstétricas usuais estiveram associados com fase de baixo vigor neurológico. Esta é uma informação útil, tanto do ponto de vista clínico quanto do médico-legal, especialmente para os obstetras. Pelos dados desta amostra, se o recém-nascido a termo é saudável, a via do nascimento e os procedimentos obstétricos usuais não têm impacto no estado neurológico. PURPOSE: to evaluate the effect of delivery type and usual obstetric procedures on the neurologic condition of a sample of consecutive term and healthy neonates, in the first 48 hours of life, using the Neurologic Adaptative Capacity Score (NACS) system. METHODS: cohort prospective study with 313 neonates, from a neonatology unit: Unidade de Neonatologia e Alojamento Conjunto. The variables analyzed were obstetric variables; clinical outcome: low neurologic vigor phase, evaluated by NACS, at 4, 24 and 48 hours of life. The data have been assessed twice: once with the whole sample and the other comparing the Vigorous Group, whose neonates kept a score of 35 or more during the three evaluations, and the Low Vigor Group, with less than 35 scores during the three consecutive evaluations. Bivariate and multivariate analyses have been done. Possible associations between low neurologic vigor phase and the type of delivery, as well between the low neurologic vigor phase and obstetric variables have been searched. RESULTS: in the bivariate analysis, the delivery type and the obstetric variables were not associated with the low neurologic vigor phase. Nevertheless, the association between the amniotic fluid and the low neurologic vigor phase reached values very close to significance and, then, it was included in the multivariate analysis. In the multivariate analysis, the only variable associated with low neurologic vigor was the presence of meconium stained amniotic fluid, which has shown to be 8.1 times more risky for the neurologic scoring, when Vigorous Group and Low Vigor Group were compared. In the analysis of the whole sample, the same risk was 1.7. CONCLUSIONS: neither the delivery type, nor the usual obstetric procedures were associated with low neurologic vigor phase. This is useful information, clinically or legally speaking, mainly for obstetricians. According to this sample data, when the term neonate is healthy, the delivery type and the usual obstetric procedures have no impact in the neurologic condition.

Introdução: O acidente vascular cerebral isquêmico (AVCI) é a patologia cerebrovascular mais comum na infância e, especialmente, na última década tem sido alvo de muitas pesquisas em todo mundo. O prognóstico do AVCI em crianças e adolescentes parece diferir conforme a população estudada e, as medidas de avaliação de cada estudo. O desfecho também parece estar relacionado à causa base da doença em relação a sua gravidade, ou seja, se o AVCI não está associado à doença grave a maioria dos pacientes tem um bom prognóstico apesar de necessitarem educação especial e uso de medicações. Objetivo: O objetivo da pesquisa é avaliar uma amostra de recém–nascidos, crianças e adolescentes com AVCI em relação a evolução. Seqüelas neurológicas motoras, na linguagem, cognição e comportamento foram as principais variáveis em questão. Metodologia: Em uma série de casos com enfoque prospectivo, foi realizado seguimento neurológico de, no mínimo, 12 meses em 91 dos 101 pacientes com diagnóstico AVCI nas idades de zero a 18 anos. Foram realizadas avaliações psicométrica e fonoaudiológica em parte da amostra. Resultados: Da amostra total, 40 eram AVCI neonatal e o território da artéria cerebral média foi o mais acometido. A média do tempo de seguimento foi de 2,5 anos e apenas 12 pacientes apresentavam exame neurológico normal. Epilepsia (40,6%), deficiência mental (66,6%), alteração na linguagem (63,6%), alteração comportamental (29,9%) e dificuldade escolar (63,6%) foram manifestações clínicas comuns tanto no AVCI neonatal como nas crianças e adolescentes. Conclusão: AVCI no recém-nascido, na criança e no adolescente é causa de seqüelas, não só motoras, mas também cognitivas e comportamentais. Não houve diferença significativa entre os grupos em relação à evolução durante o seguimento. Introduction: Ischemic stroke (IS) is the most common childhood cerebrovascular pathology and has been the subject of a great deal of research all over the world, especially during the last decade. The prognosis after IS in children and adolescents appears to differ depending on population, on the evaluation methods employed, and on the severity of the underlying disease (when IS is not associated with a severe disease, the majority of patients have good prognosis despite needing special education and medication). Objective: The objective of this study was to evaluate the progress of a sample newborns, children and adolescents with IS. The principal outcomes investigated were neurological sequelae affecting motor function, language, cognition and behavior. Methodology: In a serie of cases with a prospective approach was realized a neurological follow-up, for a minimum of 12 months, of 91 out of 101 patients diagnosed with IS at ages ranging from zero to 18 years. A proportion of this sample also underwent psychometric and speech and hearing assessments. Results: Forty cases were neonatal IS and the middle cerebral artery territory was most often affected. Mean length of follow-up was 2.5 years and only 12 patients had normal neurological examination findings. Epilepsy (40.6%), mental deficiency (66.6%), language problems (63.6%), behavioral abnormalities (29.9%), and educational difficulties (63.6%) were the most common clinical manifestations, both among the neonatal IS patients and among the children and adolescents. Conclusions: Ischemic strokes, whether in the newborn, child or adolescent, cause sequelae which are not limited to motor function, but also affect cognition and behavior. There was no differences between the groups in the follow-up evolution.

With the goal of presenting follow-up data from patients seen at the Refractory Epilepsy out-patient clinic of the Hospital de Clínicas de Porto Alegre (HCPA), Brazil, we reviewed the literature on childhood and adolescent epilepsy and epileptic syndromes with indication for surgical treatment. The International League Against Epilepsy’s Subcommission for Pediatric Epilepsy Surgery recommends surgical evaluation for cortical dysplasia, tuberous sclerosis complex, polymicrogyria, hypothalamic hamartoma, hemispheric syndromes, Sturge-Weber, Rasmussen, Landau-Kleffner and other situations such as tumors or cerebrovascular injury. The Subcommission proposes the creation of referral centers with functional methods of evaluation, structural imaging, and a multidisciplinary team that includes neurologists, neurosurgeons, neurophysiologists, neuropediatricians, neuropsychologists, pathologists, neuroradiologists and eletroneurophysiology technicians. Creating these centers in developing countries is possible with the cooperation of other regions. Studies have shown improvement in quality of life with less frequent seizures. At HCPA, we provide evaluations and ongoing clinical management of patients with medically refractory epilepsy. Epilepsy surgery is potentially curative and is particularly useful for the pediatric population. Con el objetivo de presentar el seguimiento de los pacientes ambulatorios de la clínica de epilepsia refractaria del Hospital de Clínicas de Porto Alegre (HCPA), Brasil, se hizo una revisión de la literatura de las epilepsias y síndromes epilépticos del niño y del adolescente, las indicaciones quirúrgicas y los métodos de evaluación. Los casos de epilepsia recomendados por la Subcomisión de Cirugía de la Epilepsia Pediátrica de la Liga Internacional Contra las Epilepsias para evaluación quirúrgica son: displasia cortical, esclerosis tuberosa, polimicrogiria, hamartoma hipotalámico, síndromes hemisféricos, síndromes de Sturge-Weber, Síndrome de Rasmussen, Síndrome de Landau-Kleffner y otras situaciones como tumores o alteraciones vasculares. Se recomienda la formación de centros de referencia que cuenten con métodos de evaluación funcional y de neuroimagen, así como equipo multidisciplinario formado por neurólogos, neurocirujanos, neurofisiólogos, neuropediatras, neuropsicólogos, patólogos, neurorradiólogos y técnicos en electroneurofisiología que mantengan los estándares impuestos de forma estricta. La formación de estos centros en países en desarrollo parece viable, con la cooperación de las regiones con mayores recursos. Numerosos estudios han demostrado una mejoría de la calidad de vida con reducción en la frecuencia de crisis diarias. En el HCPA se desarrolla un estudio de seguimiento ambulatorio de casos de epilepsias refractarias todavía en investigación y tratamiento clínico. La cirugía de la epilepsia es potencialmente curativa y es posible utilizarla en la población infantil.

En este trabajo de revisión se discute lo que entendemos de las funciones hemisféricas y se abordan los principales hallazgos que forman parte del síndrome del hemisferio cerebral no dominante, que en la mayor parte de los casos es el derecho, con énfasis en las alteraciones de la sustancia blanca o sea de las fibras comisurales, de asociación y de proyección. Los diferentes aspectos de los síndromes tienen relación con la etiología, localización, extensión y etapa del desarrollo en que el daño ocurrió. Se observan: hemiplejía izquierda; alteración de la prosodia, así como alteraciones en la comunicación no verbal; percepción visuo-espacial; organización, secuenciación de actividades e interacción social. Estos comportamientos se observan también en trastornos del desarrollo, tales como disturbio de déficit de atención/hiperactividad, y síndrome de Asperger. Con el objetivo de destacar cuáles son los hallazgos más frecuentes y más persistentes en niños con lesión adquirida en el hemisferio derecho, presentamos siete casos de accidente vascular isquémico. Todos los pacientes fueron controlados por más de dos años y se les realizó examen neurológico, examen neurológico evolutivo y evaluación psicológica. Con el seguimiento de los siete casos fue posible observar que las alteraciones motoras son menos severas y menos definitivas que las alteraciones cognitivas, afectivas y conductuales. In this review the meaning of cerebral hemispheric function is discussed with special emphasis in non-dominant cerebral hemisphere and particularly in the lesion of commissural, association, projection of white matter fibers. Clinical characteristics depend on etiology, localization, extension and particularly the period of brain development. The following are common findings in these patients: left hemiplegia, abnormal prosody and non verbal communication, anomalies visiospatial perception, organization, and social interaction. Similar symptoms are also present in some developmental disorders such as attention deficit hyperactive disorders and Asperger syndrome. We discuss seven cases of isquemic cerebrovascular accidents with the objective of demonstrating the more frequent and persistent findings in the acquired lesion. All patients had complete neurological and neuropsychological evaluation, and were followed up for more than two years. We conclude that motor sequel is less severe than cognitive and affective consequences.

- Abstract
Case presentation: Male, 6 years old, admitted to the hospital due to altered mental status (Glasgow Coma Scale = 3) preceded by fever, vomiting, fatigue, hypothermia and seizures. The patient presented with refractory hypoglycemia and jaundice at physical examination. Blood tests showed altered hepatic function (AST 548UI/L, ALT 2833UI/L, total bilirubin 5,81mg/dL, INR 5,2, albumin 2,4 g/dL), and serologies for viral hepatitis were negative. Acyclovir was started due to the possibility of viral encephalitis. Evaluation included electroencephalogram with signs of accentuated diffuse encephalopathy, with moderate irritative activity in the left temporal lobe; brain magnetic resonance imaging showed hyperintensity in T2/FLAIR in the periventricular and deep white matter; viral culture in the cerebrospinal fluid was positive for adenovirus. It was opted to discontinue acyclovir. He presented with improvement of lethargy and hepatic function after 5 days but evolved with irritability and ataxia. Brain magnetic resonance imaging was repeated, showing discretely larger white matter lesions, spreading to the semioval centers and corona radiata. Supportive care was continued and the patient showed normal gait and behavior after 5 days, being released with no complementary treatment. Electroencephalogram before hospital discharge showed focal paroxysms in the left parieto-occipital region, but the patient did not have new seizures. Discussion: The adenovirus family is an important cause of infection in children, with over 60 serotypes, causing more commonly respiratory and gastrointestinal infections, usually self-limited. Rarely, they can cause other types of infection, such as encephalitis, and in such cases can either cause mild or potentially fatal disease. Seizures are associated with worse prognosis. In the case above, the patient presented with associated acute hepatitis, compatible with the outbreak of adenovirus hepatitis of April of 2022. Thus, this is an unusual case characterized by systemic disease due to a common virus in childhood. There is no electroencephalogram specific or imaging findings. Treatment consists of supportive care. Final comments: Adenovirus encephalitis is a rare disease in childhood, but can cause severe neurologic complications. It must be investigated in patients with evidence of central nervous system infection, especially susceptible groups, such as immunosuppressed individuals. [ABSTRACT FROM AUTHOR]

Post-stroke seizures and epilepsy in children are a common but understudied complication. In this retrospective cohort study, the medical records of 65 children aged 0 to 18 years were analyzed to assess the risk of post-stroke seizures, detect the prevalence of post-stroke epilepsy, and ascertain which risk factors are associated with this condition in children. Forty-two patients (64.6%) had epileptic seizures following stroke (35 early, 7 late-onset), with most (78.5%) occurring in the first 24 hours. Nineteen children (29.2%) developed post-stroke epilepsy, which was significantly more common among patients with late-onset seizures (P = .034). There was a significant association between cortical involvement and development of epilepsy (P = .01). After Poisson regression, the relative risk of epilepsy was calculated as 2.4 in children with late-onset post-stroke seizures (95% confidence interval, 1.4-3.9; P = .001) and 3.7 in children with cortical involvement (95% confidence interval, 1.4-9.7; P = .009).

Objective The objective of this study is to describe the usefulness of topiramate in refractory neonatal seizures. Results We reported the clinical off-label use of topiramate in three cases of refractory neonatal seizures of unclear origin with no response to conventional antiepileptic drugs. In all cases, the seizures were completely controlled with adding topiramate. All patients became seizure free during hospitalization and were followed by approximately 1 year after hospital discharge, with monotherapy with topiramate. Comments The clinical off-label use of topiramate in neonatal seizures is still incipient. When searching publications in this matter, only one report was identified. Because of its efficacy for both seizures and neuroprotection, topiramate could be a useful choice in refractory neonatal seizures. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: During the birth, physiological changes occur in virtually all organs of the child, including the central nervous system. In this transitional phase, it is possible some degree of hypoxemia, generally well tolerated by the newborn. But, if neonatal hypoxia is intense and continuous it can lead to neonatal encephalopathy, which characterizes a critical situation for the infant. The proper approach is essential to ensure a good long-term prognosis., Development: We up-to-date information regarding hypoxia neonatal and review recent evidence-based medicine publications addressing its approach., Conclusions: Neonatal encephalopathy may be clinically classified into three levels of intensity. Mild cases usually have a good prognosis, moderate intensity cases have 30% chance of sequels, and severe intensity cases have more than 70% mortality and nearly all survivors have sequels. Recent advances occurred in two areas: in the diagnosis, with new EEG and MRI techniques, and in the treatment, with the advent of therapeutic hypothermia. There is the possibility of future use for stem cell therapy. The prognosis depends on the clinical classification, the neuroimaging data as well as the EEG.

- Abstract
The evolution of autism symptoms during life were revised, from childhood to adulthood. Little information is available. After a search in PubMed, no more than 40 publications address this issue. The review was divided into two parts: a) how change the three main symptoms of autism change; b) how change the other autism-associated symptoms. The three main symptoms, called "Triad of Wing" (communication problems, social skills deficits, and a restricted repertoire of interests) do not change significantly during lifetime. The diagnosis of autism remains stable during lifetime, and 80% of children continue with this diagnosis in adulthood. Furthermore, it is difficult to establish first diagnostic of autism in adults. In relation to the associated symptoms, one of the earliest are sleep disturbances and one of the most prevalent is both bipolar and anxiety disorders. Sleep disturbances are age-limited and disappear easily. Bipolar disorders are usually more severe in children with autism when compared to children without autism. The mood transitions are faster in autistic children. Anxiety is usually more intense in cognitive preserved autistic patients and tends to increase with age. The two main prognostic factors for autism in adults are: a) total IQ above 70. b) functional language before 6 years of age.

- Abstract
Purpose: to evaluate the effect of delivery type and usual obstetric procedures on the neurologic condition of a sample of consecutive term and healthy neonates, in the first 48 hours of life, using the Neurologic Adaptative Capacity Score (NACS) system., Methods: cohort prospective study with 313 neonates, from a neonatology unit: Unidade de Neonatologia e Alojamento Conjunto. The variables analyzed were obstetric variables; clinical outcome: low neurologic vigor phase, evaluated by NACS, at 4, 24 and 48 hours of life. The data have been assessed twice: once with the whole sample and the other comparing the Vigorous Group, whose neonates kept a score of 35 or more during the three evaluations, and the Low Vigor Group, with less than 35 scores during the three consecutive evaluations. Bivariate and multivariate analyses have been done. Possible associations between low neurologic vigor phase and the type of delivery, as well between the low neurologic vigor phase and obstetric variables have been searched., Results: in the bivariate analysis, the delivery type and the obstetric variables were not associated with the low neurologic vigor phase. Nevertheless, the association between the amniotic fluid and the low neurologic vigor phase reached values very close to significance and, then, it was included in the multivariate analysis. In the multivariate analysis, the only variable associated with low neurologic vigor was the presence of meconium stained amniotic fluid, which has shown to be 8.1 times more risky for the neurologic scoring, when Vigorous Group and Low Vigor Group were compared. In the analysis of the whole sample, the same risk was 1.7., Conclusions: neither the delivery type, nor the usual obstetric procedures were associated with low neurologic vigor phase. This is useful information, clinically or legally speaking, mainly for obstetricians. According to this sample data, when the term neonate is healthy, the delivery type and the usual obstetric procedures have no impact in the neurologic condition.

- Abstract
With the goal of presenting follow-up data from patients seen at the Refractory Epilepsy out-patient clinic of the Hospital de Clínicas de Porto Alegre (HCPA), Brazil, we reviewed the literature on childhood and adolescent epilepsy and epileptic syndromes with indication for surgical treatment. The International League Against Epilepsy's Subcommission for Pediatric Epilepsy Surgery recommends surgical evaluation for cortical dysplasia, tuberous sclerosis complex, polymicrogyria, hypothalamic hamartoma, hemispheric syndromes, Sturge-Weber, Rasmussen, Landau-Kleffner and other situations such as tumors or cerebrovascular injury. The Subcommission proposes the creation of referral centers with functional methods of evaluation, structural imaging, and a multidisciplinary team that includes neurologists, neurosurgeons, neurophysiologists, neuropediatricians, neuropsychologists, pathologists, neuroradiologists and eletroneurophysiology technicians. Creating these centers in developing countries is possible with the cooperation of other regions. Studies have shown improvement in quality of life with less frequent seizures. At HCPA, we provide evaluations and ongoing clinical management of patients with medically refractory epilepsy. Epilepsy surgery is potentially curative and is particularly useful for the pediatric population.

- Abstract
In this review the meaning of cerebral hemispheric function is discussed with special emphasis in non-dominant cerebral hemisphere and particularly in the lesion of commissural, association, projection of white matter fibers. Clinical characteristics depend on etiology, localization, extension and particularly the period of brain development. The following are common findings in these patients: left hemiplegia, abnormal prosody and non verbal communication, anomalies visiospatial perception, organization, and social interaction. Similar symptoms are also present in some developmental disorders such as attention deficit hyperactive disorders and Asperger syndrome. We discuss seven cases of isquemic cerebrovascular accidents with the objective of demonstrating the more frequent and persistent findings in the acquired lesion. All patients had complete neurological and neuropsychological evaluation, and were followed up for more than two years. We conclude that motor sequel is less severe than cognitive and affective consequences.
