Características clínicas e sociodemográficas dos usuários de um centro de atenção psicossocial infantojuvenil em Porto Alegre a partir do Sistema de Gerenciamento de Consultas (GERCON) / Clinical and sociodemographic characteristics of users of centro de atenção psicossocial infantojuvenil in Porto Alegre since the implementation of Sistema de Gerenciamento de Consultas (GERCON)

Introdução: Desde maio de 2019, o acesso aos serviços especializados de saúde mental infantojuvenil do município de Porto Alegre ocorre através da regulação assistencial por intermédio do sistema Gerenciamento de Consultas (GERCON). O objetivo deste estudo foi caracterizar o perfil clínico e sociodemográfico dos usuários encaminhados para um Centro de Atenção Psicossocial Infantojuvenil (CAPSi) nos dois primeiros anos do GERCON. Métodos: Estudo transversal em que foram resgatados dados dos prontuários eletrônicos de crianças e adolescentes encaminhados para primeira consulta em um CAPSi de Porto Alegre, capital do estado do Rio Grande do Sul, no período de maio de 2019 a abril de 2021. Resultados: A maioria dos 134 usuários era do sexo masculino (59,8%), autodeclarados brancos (69,7%), naturais de Porto Alegre (87,9%) e com hipótese diagnóstica inicial de Retardo mental (28,9%), Transtornos emocionais e de comportamento com início usualmente ocorrendo na infância e adolescência (24,2%) e Transtornos do humor (20,3%). A média de idade foi 13,4 anos e a mediana 15 anos. A taxa de absenteísmo na primeira consulta foi de 24,7%. Conclusão: A maioria dos usuários encaminhados para o CAPSi HCPA era do sexo masculino, adolescente, natural de Porto Alegre e com a hipótese diagnóstica inicial de transtornos do neurodesenvolvimento. Há uma elevada taxa de absenteísmo. Ao planejar intervenções para crianças e adolescentes que necessitam de atendimento em CAPSi é importante considerar o perfil nosológico e as características sociodemográficas dos usuários, assim como pensar em estratégias para diminuir o absenteísmo.

Introduction: Since May 2019, access to child and adolescent mental health services in the city of Porto Alegre has been managed through a regulatory system called sistema de regulação assistencial (GERCON). The aim of this study is to describe the clinical and sociodemographic characteristics of users referred to a Child and Adolescent Psychosocial Care Center (Centro de Atenção Psicossocial Infantojuvenil [CAPSi]) in the first two years of GERCON. Methods: This is a cross-sectional study. Data were retrieved from electronic medical records of children and adolescents referred for their first consultation at a CAPSi in Porto Alegre, capital of the state of Rio Grande do Sul, from May 2019 to April 2021. Results: Most of the 134 users were male (59.8%), self declared white (69.7%), from Porto Alegre (87,9%) and with an initial diagnostic hypothesis of Mental retardation (28,9%), Behavioral and emotional disorders with onset usually occurring in childhood and adolescence (24,2%) e Mood disorders (20,3%). The mean age was 13.4 years and the median was 15 years. The rate of absenteeism in the first appointment was 24.7%. Conclusion: Most users referred to the CAPSi HCPA were male, teenagers, born in Porto Alegre and with the initial diagnostic hypothesis of neurodevelopmental disorders. There is a high rate of absenteeism. When planning interventions for children and adolescents who need CAPSi care, it is important to consider the nosological profile and sociodemographic characteristics, as well as thinking about strategies to reduce absenteeism.

Resultados en el neurodesarrollo en la edad preescolar y escolar de los recién nacidos pretérminos asistidos en el CTI neonatal de la Asociación Médica de San José / Neurodevelopmental preschool and school results of preterm newborns assisted at the neonatal ICU of the San José department medical provider in Uruguay / Resultados neuro desenvolvimento em idade pré-escolar e escolar de recém-nascidos pré-termos atendidos na UTI neonatal da assistência médica do departamento do São José no Uruguai

Uruguay acompaña la tendencia mundial al descenso de la natalidad con un descenso de la mortalidad concomitante, siendo la primera causa de mortalidad infantil la prematurez. Enfocados en la prematurez, es de nuestro interés conocer qué ocurre con estos niños luego del alta de la unidad neonatal. Se realizó el estudio de una cohorte de niños entre 4 y 8 años, nacidos con 32 semanas o menos de edad gestacional y/o con pesos al nacer de 1.500 g o menos, asistidos en su período neonatal en la Asociación Médica de San José, a quienes se les realizó el test de Battelle. Se logró identificar las áreas con mayor dificultad en el desarrollo para cada grupo de edad, concluyendo que se pueden realizar planes específicos de acción para promover el desarrollo de estos niños en la edad preescolar y escolar.

Uruguay follows the global declining trend in birth rates along with decreasing mortality, being prematurity the main cause of infant mortality. We studied premature children who had undergone the Battelle Test and had been discharged from the neonatal unit, a cohort of children between 4 and 8 years of age, born at 32 weeks or less of gestational age and/or having a birth weight of 1500g or less, assisted in their neonatal period at the San José Department Medical Center. We could identify the main areas affecting development for each age group, and concluded that specific action plans can be carried out to promote the development of these children at preschool and school age.

O Uruguai acompanha a tendência mundial de declínio das taxas de natalidade com uma concomitante diminuição da mortalidade, sendo a prematuridade a principal causa de mortalidade infantil. Nos focamos na prematuridade e no estudo do que acontece com essas crianças após a alta da unidade neonatal. Realizamos um estudo de uma coorte de crianças entre 4 e 8 anos que tinham sido submetidas ao Teste de Battelle, nascidas com 32 semanas ou menos de idade gestacional e/ou com peso de nascimento igual ou inferior a 1500g, atendidas no período neonatal na Assistência Médica do Departamento de São José no Uruguai. Foi possível identificar as áreas de maior dificuldade de desenvolvimento para cada faixa etária, e concluir que podem se realizar planos de ação específicos para promover o desenvolvimento dessas crianças em idade pré-escolar e escolar.

Itinerarios de tratamiento según las narrativas de madres y padres de niños y niñas con discapacidad secundaria a trastornos del neurodesarrollo / Therapeutic itineraries according to the narratives of parents of children with disabilities secondary to neurodevelopmental disorders

Introducción. Los trastornos en el neurodesarrolloinfantil constituyen un 10 % de las causasde discapacidad en la niñez. La búsquedade atención médica configura itinerariosterapéuticos, entendidos como los procesos de búsqueda y atención para el cuidado de la salud, donde surgen oportunidades de diagnósticoy tratamiento. El objetivo fue explorar dichos itinerarios para comprender las oportunidades y barreras que se presentan para instaurarterapias y pautas de crianza que promuevan el neurodesarrollo. Población y métodos. Estudio cualitativomediante entrevistas en profundidad a madres y padres de niños (de junio de 2018 a noviembre de 2019). El análisis se realizó sobre la base del modelo social de la discapacidad y del de desarrollo infantil propuesto por Vygotsky. Resultados. Se realizaron 16 entrevistas.Considerando la edad de inicio de los itinerarios terapéuticos y el diagnóstico, se identificaron dos grupos: aquellos que los comenzaron desde el nacimiento hasta los 2 años (inicio precoz) y quienes lo hicieron a partir de los 3 años (inicio en la primera infancia e infancia tardía). En el primero se habilita tempranamente la búsqueda de tratamiento, mientras que en el segundo se prolongaron en el tiempo las decisiones sobre el inicio y/o el tipo de terapias. El inicio tardío se acompañó de dificultades en la escuela, períodosde incertidumbre, angustia y/o conflictosfamiliares por las complejidades de la crianza. Conclusiones. Los itinerarios terapéuticos seiniciaron en forma precoz en algunos casos y tardía en otros. El inicio de tratamientos permitióincorporar herramientas para acortar la brecha de incongruencia entre las líneas biológica y cultural de desarrollo.

Introduction. Childhood neurodevelopmental disorders account for 10% of the causes of childhood disability. The search for medical care leads to therapeutic itineraries routes taken by individuals to seek health care where diagnostic and treatment opportunities arise. Our objective was to explore these itineraries in order to understand the opportunities and barriers to the implementation of therapies and child rearing patterns promoting neurodevelopment. Population and methods. Qualitative study using in-depth interviews with children's parents (between June 2018 and November 2019). The analysis was based on the social model of disability and Vygotsky's approach to child development. Results. A total of 16 interviews were conducted. Considering the time of diagnosis and the age when the therapeutic itinerary started, 2 groups were identified: those who started from birth to 2 years old (early initiation) and those who started from 3 years old (late childhood initiation). In the first group, the search for treatment starts at an early stage, while in the other group, decisions on the initiation and/or type of treatments are prolonged over time. Late initiation was accompanied by difficulties in school, periods of uncertainty, distress and/or family conflicts due to the complexities of parenting. Conclusions. Therapeutic itineraries started early in some cases and at a later stage in others. The initiation of treatments made it possible to use tools to bridge the gap of discrepancies between the biological and cultural lines of development.

Neurodevelopment in the third year of life in children with antenatal ZIKV-exposure

ABSTRACT We report cognitive, language and motor neurodevelopment, assessed by the Bayley-III test, in 31 non-microcephalic children at age 3 with PCR-confirmed maternal Zika virus exposure (Rio de Janeiro, 2015-2016). Most children had average neurodevelopmental scores, however, 8 children (26%) presented delay in some domain. Language was the most affected: 7 children (22.6%) had a delay in this domain (2 presenting severe delay). Moderate delay was detected in the cognitive (3.2%) and motor (10%) domains. Maternal illness in the third trimester of pregnancy and later gestational age at birth were associated with higher Bayley-III scores. Zika-exposed children require long-term follow-up until school age.

Hokkaido birth cohort study on environment and children's health: cohort profile 2021

BACKGROUND@#The Hokkaido Study on Environment and Children's Health is an ongoing study consisting of two birth cohorts of different population sizes: the Sapporo cohort and the Hokkaido cohort. Our primary objectives are to (1) examine the effects that low-level environmental chemical exposures have on birth outcomes, including birth defects and growth retardation; (2) follow the development of allergies, infectious diseases, and neurobehavioral developmental disorders, as well as perform a longitudinal observation of child development; (3) identify high-risk groups based on genetic susceptibility to environmental chemicals; and (4) identify the additive effects of various chemicals, including tobacco.@*METHODS@#The purpose of this report is to provide an update on the progress of the Hokkaido Study, summarize recent results, and suggest future directions. In particular, this report provides the latest details from questionnaire surveys, face-to-face examinations, and a collection of biological specimens from children and measurements of their chemical exposures.@*RESULTS@#The latest findings indicate different risk factors of parental characteristics on birth outcomes and the mediating effect between socioeconomic status and children that are small for the gestational age. Maternal serum folate was not associated with birth defects. Prenatal chemical exposure and smoking were associated with birth size and growth, as well as cord blood biomarkers, such as adiponectin, leptin, thyroid, and reproductive hormones. We also found significant associations between the chemical levels and neuro development, asthma, and allergies.@*CONCLUSIONS@#Chemical exposure to children can occur both before and after birth. Longer follow-up for children is crucial in birth cohort studies to reinforce the Developmental Origins of Health and Disease hypothesis. In contrast, considering shifts in the exposure levels due to regulation is also essential, which may also change the association to health outcomes. This study found that individual susceptibility to adverse health effects depends on the genotype. Epigenome modification of DNA methylation was also discovered, indicating the necessity of examining molecular biology perspectives. International collaborations can add a new dimension to the current knowledge and provide novel discoveries in the future.

Diabetes materna y trastornos del neurodesarrollo en los hijos / Maternal diabetes and neurodevelopmental disorders in offspring

Resumen La diabetes durante el embarazo se asocia a un mayor riesgo perinatológico para los niños. Este puede reducirse significativamente con un control glucémico adecuado en estadios tempranos de la gestación. En la última década nuevos estudios han mostrado los efectos deletéreos de la diabetes materna en la salud de los hijos a largo plazo, como las alteraciones del neurodesarrollo y los efectos sobre el pronóstico educacional y ocupacional. Las mismas pueden ser clasificadas, desde el punto de vista clínico-diagnóstico en tres grupos principales: trastornos del aprendizaje y del desarrollo intelectual, trastorno por déficit de atención e hiperactividad y trastornos del espectro autista. El presente trabajo tiene como objetivo realizar una actualización no sistemática de la evidencia más reciente en el tema y comprender los mecanismos subyacentes que provocan el daño, con el fin de desarrollar estrategias preventivas.

Abstract Diabetes during pregnancy is associated with adverse effects on offspring perinatal outcomes. These could be reduced significantly with an adequate glycemic control in early stages of gestation. In the last decade, new studies have shown the effects of maternal diabetes in the long-term health of the offspring, like impaired neurodevelopment and its impact on educational and occupational outcome. This can be classified, from the clinical and diagnostic perspective, in three main groups: learning and cognitive disorders, attention deficit hyperactivity disorder and autism spectrum disorders. This paper has the objective to give a non-systematic upgrade of the current evidence on the subject, and to understand the underlying mechanisms of adverse neurodevelopmental outcomes which in turn may lead to strategies for its prevention.

Algoritmo para el diagnóstico de pacientes con trastornos del neurodesarrollo y sospecha de un síndrome genético / Algorithm for the diagnosis of patients with neurodevelopmental disorders and suspicion of a genetic syndrome

El amplio espectro de aberraciones cromosómicas observable en los trastornos del neurodesarrollo no siempre puede ser caracterizado por análisis cromosómico. El objetivo del trabajo fue determinar la etiología genética de estos trastornos en pacientes con afecciones neurológicas congénitas y sospecha clínica de un síndrome genético, aplicando un algoritmo de estudio clínico-molecular. En 71 de 111 niños analizados, se hallaron aberraciones submicroscópicas asociadas a síndromes de microdeleción-microduplicación: DiGeorge (22 casos), Prader-Willi (26 casos), Angelman (2 casos), Williams-Beuren (17 casos), Smith-Magenis (1 caso), Miller-Dieker (1 caso) y síndrome cri du chat (1 caso). Adicionalmente, se detectó una inserción desbalanceada de novo de la región 17p12p11.2, en el punto 5p13.1, en un niño de tres años. La utilización del método clínico unido a técnicas moleculares, como hibridación fluorescente in situ, ha permitido, en la mayoría de los casos, el diagnóstico certero de pacientes y/o familias con trastornos del neurodesarrollo.

The wide range of chromosome aberrations seen in neurodevelopmental disorders may not always be characterized by means of a chromosome analysis. The objective of this study was to determine the genetic etiology of these disorders in patients with congenital neurological conditions and clinical suspicion of a genetic disorder using a clinical and molecular testing algorithm. Among 111 studied children, 71 showed submicroscopic chromosome aberrations associated with microdeletion/microduplication syndromes: DiGeorge (22 cases), Prader-Willi (26 cases), Angelman (2 cases), Williams-Beuren (17 cases), Smith-Magenis (1 case), Miller-Dieker (1 case), and cri du chat syndrome (1 case). Additionally, a de novo trisomy 17p12p11.2 due to an unbalanced insertion into 5p13.1 was identified in a 3-year-old child. In most cases, the use of a clinical method together with molecular techniques, such as fluorescence in situ hybridization, has allowed to make an accurate diagnosis in patients and/or families with neurodevelopmental disorders.

RESUMO As cardiopatias congênitas (CC) estão entre as principais causas de morbimortalidade na primeira infância e os lactentes com essa condição podem apresentar atrasos no desenvolvimento neuropsicomotor (DNPM). O objetivo deste estudo foi avaliar a influência da CC no DNPM de lactentes. Trata-se de um estudo observacional com avaliação do desenvolvimento neuropsicomotor realizada pela Bayley Scales of Infant and Toddler Development (BSID-III). As condições maternas e clínicas dos lactentes foram verificadas no relatório de alta médica e na caderneta de saúde da criança, e a condição socioeconômica das famílias pelo Critério da Classificação Econômica Brasil. Para associar as variáveis clínicas e o DNPM foram utilizados o coeficiente de correlação de Spearman e o teste de razão de verossimilhança. Foram avaliados 18 lactentes, com predomínio do sexo feminino (72,2%). A maioria das mães (47,1%) possuía ensino médio completo ou superior incompleto, com média da idade de 27,2±5,5 anos. Houve correlação das escalas do BSID-III com as variáveis quantitativas analisadas: escala motora com o peso (p=0,02 e r=0,54) e com uso de oxigenoterapia (p=0,009 e r=−0,591); já para as variáveis qualitativas as associações foram entre: escala motora e condição socioeconômica (p=0,015), escala motora e comunicação interatrial - (CIA) (p=0,023) e escala da linguagem e CIA (p=0,038). A CC influenciou o DNPM, principalmente no aspecto motor. Além disso peso, diagnóstico de CIA, uso de oxigenoterapia e condição socioeconômica foram considerados como principais fatores de risco para o atraso no DNPM.

ABSTRACT Congenital heart defects (CHD) are among the main causes of morbidity and mortality in infants who has this impairment may present delays in neuropsychomotor development (NPMD). This study assesses the influence of CHD on NPMD of infants. This is an observational study assessing neuropsychomotor development performed by Bayley Scales of Infant and Toddler Development - BSID-III. The Brazilian Economic Classification Criteria was used to verify the socioeconomic status of the families and also the maternal and infants' clinical conditions were verified in the medical discharge report and in the child's health handbook. For the association between the quantitative and qualitative variables with the NPMD, the Spearman's correlation coefficient and the likelihood ratio test were used. A total of 18 infants were assessed, with a predominance of females (72.2%). Most mothers (47.1%) had complete high school or incomplete higher education, with a mean age of 27.2±5.5 years. There was a correlation between the BSID-III scales and the quantitative variables analyzed: motor scale with weight (p=0.02 and r=0.54) and oxygen therapy (p=0.009 and r=−0.591); besides that, the qualitative variables correlation were: motor scale and socioeconomic condition (p=0.015), motor scale and Interatrial Communication - IAC (p=0.023) and language with IAC scales (p=0.038). CHD influences the delay of NPMD, mainly for motor aspect. Furthermore, weight, diagnosis of IAC, use of oxygen therapy and socioeconomic status were considered the main risk factors for the delay in NPMD.

Cardiopatías congénitas y desarrollo del cerebro fetal artículo de revisión / Congenital heart disease and fetal brain development: review

La enfermedad cardíaca congénita se ha asociado con alteraciones del neurodesarrollo. Niños y adolescentes con cardiopatía congénita presentan déficits en distintos dominios neurológicos (motor, cognitivo, lenguaje, rendimiento escolar y habilidades sociales). Históricamente se atribuyeron a una potencial injuria cerebral durante la cirugía cardíaca. Sin embargo, evidencia actual demuestra que RN de término ya presentan anormalidades cerebrales y retraso de la maduración (dismaduración) con alta prevalencia 28% (IC 95%, 18-40%) Entre ellas se reporta ventriculomegalia, agenesia cuerpo calloso, hipoplasia de vermis, hemorragia intraventricular, aumento espacio subaracnoídeo, alteraciones de la sustancia blanca (Leucomalacia periventricular), desarrollo cortical alterado y quistes periventriculares. El mecanismo más estudiado es la interferencia de la cardiopatía con el shunt fisiológico de derecha a izquierda por el foramen ovale, que asegura la llegada de la sangre mejor oxigenada primeramente al cerebro. Se discute el beneficio de potenciales intervenciones prenatales neuroprotectoras y el diagnóstico temprano de cardiopatías congénitas.

Congenital heart disease has been associated with neurodevelopmental disorders. Children and adolescents with congenital heart disease present deficits in different neurological domains (motor, cognitive, language, school performance and social skills). Historically they were attributed to a potential brain injury during cardiac surgery. However, current evidence shows that term newborns already present brain abnormalities and delay of maturation (dysmaturation) with high prevalence 28% (95% CI, 18-40%) Among them is reported ventriculomegaly, Corpus Callosum agenesis, hypoplastic vermis, intraventricular hemorrhage, subarachnoid space enlargement, white matter alterations (periventricular leukomalacia), altered cortical development and periventricular cysts. The most studied mechanism is the interference of heart disease with the physiological shunt from right to left by the foramen ovale, which ensures the arrival of the best oxygenated blood first to the brain. The benefit of potential neuroprotective prenatal interventions and early diagnosis of congenital heart diseases is discussed.

Male sex is an independent risk factor for poor neurodevelopmental outcome at 20 months' corrected age, in human milk-fed very preterm infants: a cohort study / O sexo masculino é fator de risco independente para pior desenvolvimento neurológico na idade corrigida de 20 meses, em lactentes muito prematuros e alimentados com leite humano: estudo de coorte

ABSTRACT Objective: To determine associations between sex and neurodevelopmental outcomes in human milk-fed very preterm infants, adjusted to early measured nutrient intakes and other neonatal cofactors. Methods: Consecutive inborn human milk-fed infants, with gestational age <33 weeks, were eligible. In-hospital energy and protein intakes have relied on measured human milk composition. The Bayley Scales of Infant Development II mental and psychomotor developmental indexes were used to assess neurodevelopment at 20 months' corrected age. After univariate analysis, some covariables were used for linear multiple regression. Results: Thirty-two infants were included, with a mean (standard deviation) gestational age of 29.8 (1.8) weeks, and a median birth weight of 1168g (interquartile range 990-1419g). Minimum recommended intakes were achieved in 63.6% and 15.2% of infants for protein and energy, respectively. The mental and psychomotor developmental indexes were within normal limits in 93.8% of infants. The mean mental and psychomotor developmental indexes were significantly lower in males. Only male sex negatively and significantly affected the mental and psychomotor developmental indexes (B=-9.44; 95%CI: -17.64- -1.23; adjusted r2=0.17; p=0.026), adjusted to gestational age and measured energy intake. Conclusion: In human milk-fed very preterm infants, males had a significantly lower mental and psychomotor developmental indexes score at 20 months' corrected age, adjusted for gestational age and measured energy intake.

RESUMO Objetivo: Determinar a associação entre sexo e desfechos relativos ao neurodesenvolvimento em lactentes muito prematuros e alimentados com leite humano, ajustada para a ingestão de nutrientes medida nos primeiros dias de vida e outros cofatores neonatais. Métodos: Consideramos, para este estudo, lactentes alimentados com leite humano, consecutivamente nascidos em um centro especializado, com idade gestacional <33 semanas. A ingestão intra-hospitalar de energia e proteínas baseou-se na composição medida do leite humano. Os índices de desenvolvimento mental e psicomotor das Bayley Scales of Infant Development II foram usados para avaliar o neurodesenvolvimento na idade corrigida de 20 meses. Após a análise univariada, algumas covariáveis foram usadas para a regressão múltipla linear. Resultados: Incluímos 32 lactentes, com idade gestacional média (desvio padrão) de 29,8 (1,8) semanas e mediana de peso ao nascimento de 1168g (intervalo interquartil: 990-1419g). A ingestão mínima recomendada foi atingida em 63,6% e 15,2% dos lactentes, para proteínas e energia, respectivamente. Os índices de desenvolvimento mental e psicomotor ficaram dentro dos limites normais em 93,8% dos lactentes. A pontuação média nos índices de desenvolvimento mental e psicomotor foi significativamente menor no bebês do sexo masculino. Somente o sexo masculino afetou negativa e significativamente os índices de desenvolvimento mental e psicomotor (B=-9,44; IC95%: -17,64- -1,23; r2 ajustado=0,17; p=0,026), ajustados para idade gestacional e ingestão de energia medida. Conclusão: Em lactentes muito prematuros e alimentados com leite humano, o sexo masculino teve pontuação significativamente mais baixa nos índices de desenvolvimento mental e psicomotor na idade corrigida de 20 meses, ajustada para idade gestacional e ingestão de energia medida.

Estudio comparativo de funciones neuropsicológicas a los 8 años de niños prematuros y nacidos de término / Comparative study of neupsychological functions in preterm and term childrens at eight years old

INTRODUCCIÓN: El seguimiento de niños nacidos prematuros extremos de edad escolar revela menor desarrollo de funciones neuropsicológicas, en comparación con sus pares nacidos de término. OBJETIVO: Comparar las funciones neuropsicológicas de escolares con antecedente de prematuridad y niños de término alrededor de los 8 años de edad. PACIENTES Y MÉTODO: Investigación no experimental, cuantitativa, de diseño correlacional. Se incluyeron 43 niños nacidos con menos de 1500 grs. de peso y/o menos 32 semanas de gestación, y un grupo control constituído por 40 niños de término, compañeros de curso del grupo muestra. Ambos grupos sin diagnóstico de discapacidad neurológica, sensorial ni cognitiva. Los padres firmaron documento de consentimiento informado y se recopila ron datos por medio de la Evaluación Neuropsicológica Infantil-ENI 2, que evalúa las características neuropsicológicas de niños y jóvenes entre 5 y 16 años a través de 14 procesos neuropsicológicos: habilidades construccionales, memoria, habilidades perceptuales, lenguaje, habilidades metalingüísticas, lectura, escritura, aritmética, habilidades espaciales, atención, habilidades conceptuales, fluidez, flexibilidad cognoscitiva y planeación. Datos obtenidos se analizaron con prueba Kruskal Wallis, estableciéndose nivel de significación en p < 0,05. RESULTADOS: Los hallazgos de la investigación coinciden parcialmente con problemas globales referidos por la literatura. En general se observa menor puntaje estándar a menor edad gestacional. Se encontraron diferencias significativas en sub pruebas de habilidades gráficas, percepción auditiva, atención auditiva y flexibilidad cognoscitiva. CONCLUSIONES: Los niños con antecedente de prematuridad extrema que participaron en la investigación evidencian una variedad de déficits en funciones neuropsicológicas, aunque su rendimiento, al igual que el del grupo control, es disarmónico, con puntajes altos en algunos ítems y bajos en otros.

INTRODUCTION: Monitoring of extremely preterm infants of school age reveals poor development of neuropsychological functions, compared to their full term peers. OBJECTIVE: To compare the neurop sychological functions of schoolchildren with history of extreme prematurity and full term children of the same age. PATIENTS AND METHOD: Non-experimental, cross-sectional research. Forty-three pre term children who born weighting less than 1,500 g and/or less than 32 weeks of gestational age and a control group made up of forty full-term children, classmates of the sample group were included. Both groups had no diagnosis of neurological, sensory or cognitive disability. Parents signed infor med consent forms and data were collected through the Child Neuropsychological Assessment-ENI2, which considers 14 items: construction skills, memory, Perceptual skills, language, metalinguistic skills, reading, writing, arithmetic, skills spatial, attention, conceptual skills, fluency, cognitive flexi bility and planning. Data obtained were analyzed with Kruskal-Wallis test, establishing significance level at p < 05. RESULTS: Research findings partially agree with problems reported in the literature. In general, a lower standard score was observed at lower gestational age. There were significant differen ces in subtests of graphical skills, auditory perception, auditory attention, and cognitive flexibility. CONCLUSIONS: Children with history of extreme prematurity who participated in this research showed a variety of deficits in neuropsychological functions, although their performance, as well as that of the control group, is disharmonic, with high scores in some items and low ones in others.

Neurological Outcome in Fetuses with Mild and Moderate Ventriculomegaly / Resultado neurológico em fetos com ventriculomegalia leve e moderada

Abstract Introduction Ventriculomegaly (VM) is one the most frequent anomalies detected on prenatal ultrasound. Magnetic resonance imaging (MRI) may enhance diagnostic accuracy and prediction of developmental outcome in newborns. Purpose The aim of this study was to assess the correlation between ultrasound and MRI in fetuses with isolated mild and moderate VM. The secondary aim was to report the neurodevelopmental outcome at 4 years of age. Methods Fetuses with a prenatal ultrasound (brain scan) diagnosis of VM were identified over a 4-year period. Ventriculomegaly was defined as an atrial width of 10- 15 mm that was further divided as mild (10.1-12.0 mm) and moderate (12.1-15.0 mm). Fetuses with VM underwent antenatal as well as postnatal follow-ups by brain scan and MRI. Neurodevelopmental outcome was performed using the Griffiths Mental Development Scales and conducted, where indicated, until 4 years into the postnatal period. Results Sixty-two fetuses were identified. Ventriculomegaly was bilateral in 58% of cases. A stable dilatation was seen in 45% of cases, progression was seen in 13%, and regression of VM was seen in 4.5% respectively. Fetal MRI was performed in 54 fetuses and was concordant with brain scan findings in 85% of cases. Abnormal neurodevelopmental outcomes were seen in 9.6% of cases. Conclusion Fetuses in whom a progression of VM is seen are at a higher risk of developing an abnormal neurodevelopmental outcome. Although brain scan and MRI are substantially in agreement in defining the grade of ventricular dilatation, a low correlation was seen in the evaluation of VM associated with central nervous system (CNS) or non-CNS abnormalities.

Resumo Introdução Ventriculomegalia (VM) é uma das anomalias mais frequente no ultrassom pre-natal. Ressonâncias magnéticas (RM) melhoram a precisão do diagnóstico e previsão do desenvolvimento em recém-nascidos. Objetivo A proposta deste estudo foi avaliar a correlação entre ultrassom e RM em fetos com leve e moderada VM isolada. O objetivo secundário foi reportar o resultado neurológico na idade de 4 anos. Métodos Fetos com diagnóstico pré-natal pelo ultrassom de VM foram identificados na idade de 4 anos. Ventriculomegalia foi definida como medida do átrio do ventrículo lateral entre 10-15 mm, a qual foi subdividida em leve (10,1-12,0 mm) e moderada (12,1-15,0 mm). Fetos com VM foram seguidos nos períodos pré-natal e pós-natal por ultrassom e RM. O resultado neurológico foi realizado usando a escala de desenvolvimento mental de Griffiths, quando indicada, até a idade de 4 anos. Resultados Sessenta e dois fetos foram identificados. Ventriculomegalia bilateral ocorreu sem 58% dos casos. Uma dilatação estável foi observada em 45%, progressiva em 13% e regressiva em 4,5% dos casos, respectivamente. Ressonância magnética fetal foi realizada em 54 fetos, e foi concordante com os achados do ultrassom em 85% dos casos. Desenvolvimento neurológico anormal foi observado em 9,6% dos casos. Conclusão Fetos nos quais ocorreu progressão da VM são de alto risco para desenvolvimento neurológico anormal. Apesar do ultrassom e da RM mostrarem substancial concordância na definição do grau de dilatação ventricular, uma baixa correlação foi vista na avaliação da VM associada ou não com anomalias do sistema nervoso central.

Twin-twin transfusion syndrome: neurodevelopment of infants treated with laser surgery / Síndrome de transfusão feto-fetal: neurodesenvolvimento de lactentes tratados com cirurgia a laser

ABSTRACT Objective To assess the neurodevelopmental functions of survivors of twin-twin transfusion syndrome (TTTS) treated by fetoscopic laser coagulation (FLC), during the first year of life, comparing them to a control group; and to verify the influence of specific variables on neurodevelopment. Method This was a prospective, longitudinal study. The sample comprised 33 monochorionic diamniotic twins who underwent FLC for treatment of TTTS and 22 full-term infants of single-fetus pregnancies. Bayley Scales of Infant and Toddler Development Screening Test were used for evaluation. Prenatal, perinatal and postnatal information were obtained. Results There was an increased frequency of infants in the TTTS group with inadequate performance compared to the control group. The identified variables (fetal donor, low economic income and cardiorespiratory disease) negatively impacted expressive communication and fine motor skills. Conclusion Although through follow-up is recommended in all TTTS survivors, particular attention is required for the high-risk group as defined in this study.

RESUMO Objetivo Avaliar o desenvolvimento neurológico de sobreviventes da sindrome de transfusão feto-fetal (STFF) submetidos à coagulação a laser por fetoscopia (CLF), durante o primeiro ano de vida, comparando estes ao grupo controle; e verificar a influência de variáveis específicas no desenvolvimento. Método Tratou-se de estudo prospectivo, longitudinal. A amostra foi composta por 33 gêmeos diamnióticos monocoriônicos submetidos à CLF para tratamento da STFF e 22 lactentes a termo de gestação única. Bayley Scales of Infant and Toddler Development Screening Test foram utilizadas para avaliação. Informações pré-natal, perinatal e pós-natal foram coletadas. Resultados Houve maior número de lactentes com desempenho inadequado no grupo STFF do que no controle. As variáveis identificadas (feto doador, baixa renda econômica e doença cárdio-respiratória) influenciaram negativamente a comunicação expressiva e as habilidades motoras finas. Conclusão Embora o acompanhamento seja recomendado para todos lactentes com STFF, especial atenção deve ser dada àqueles que apresentam fatores de risco.
