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.

PURPOSE: To compare motor and cognitive performance in infants with typical development in the 1st, 2nd, 3rd, 6th, 9th, and 12th months after birth. METHODS: This was a repeated-measures study with unequal sample sizes in the follow-up periods, comprising 94 infants born at term. Infants with genetic syndromes, malformations, congenital infections, or hospitalized in intensive care units were excluded. The Bayley Scales of Infant Development II were used for evaluation of cognitive and motor performance. RESULTS: There were significant differences between motor and cognitive performance at 1, 2, and 3 months. However, at 6, 9, and 12 months, there was no difference between domains. CONCLUSION: This study suggests that during the first year, development can be synchronous in the 2 areas evaluated by the Bayley Scales of Infant Development II, especially from the sixth month of age onward.

BACKGROUND: many clinicians and researchers in Brazil consider the Neurological Developmental Exam (NDE), a valid and reliable assessment for Brazilian school-aged children. However, since its inception, several tests have emerged that, according to some researchers, provide more in-depth evaluation of motor ability and go beyond the detection of general motor status (soft neurological signs). OBJECTIVES: to highlight the limitations of the NDE as a motor skill assessment for first graders. METHODS: thirty-five children were compared on seven selected items of the NDE, seven of the Bruininks-Oseretsky Test (BOT), and seven of the Visual-Motor Integration test (VMI). Participants received a "pass" or "fail" score for each item, as prescribed by the respective test manual. RESULTS: chi-square and ANOVA results indicated that the vast majority of children (74%) passed the NDE items, whereas values for the other tests were 29% (BOT) and 20% (VMI). Analysis of specific categories (e.g. visual, fine, and gross motor coordination) revealed a similar outcome. CONCLUSIONS: our data suggest that while the NDE may be a valid and reliable test for the detection of general motor status, its use as a diagnostic/remedial tool for identifying motor ability is questionable. One of our recommendations is the consideration of a revised NDE in light of the current needs of clinicians and researchers.

CONTEXTUALIZAÇÃO: Muitos clínicos e pesquisadores brasileiros consideram o Exame Neurológico Evolutivo (ENE), um instrumento válido e confiável para crianças brasileiras em idade escolar. Entretanto, desde a sua criação, surgiram outros testes para uma avaliação mais profunda de habilidade motora, os quais vão além de detectar status motor geral em forma de sinais neurológicos leves. OBJETIVOS: Demonstrar os pontos fracos do ENE como teste de avaliação de habilidade motora para crianças de primeira série. MÉTODOS: Trinta e cinco crianças realizaram 7 itens selecionados do ENE, 7 do teste Bruininks-Oseretsky (BOT) e 7 do Visual-Motor Integration Test (VMI), numa sessão única de 30 minutos. Para cada item, os participantes receberam a classificação "êxito" ou "fracasso", como prescrito por cada manual. RESULTADOS: Os testes chi-quadrado e ANOVA indicaram que a vasta maioria das crianças (74 por cento) passaram nos itens do ENE, enquanto os valores para os outros testes foram 29 por cento (BOT) e 20 por cento (VMI). Análises das categorias específicas (fino, visual e motor grosso) revelaram um resultado similar. CONCLUSÕES: Estes dados sugerem que, enquanto o ENE pode ser um teste válido e confiável para detecção de status motor geral, a sua atuação como instrumento diagnóstico e de encaminhamento para identificação de habilidade motora é questionável. Uma das nossas recomendações é a consideração de uma versão do ENE revisada, baseada nas necessidades atuais de profissionais clínicos e pesquisadores.

OBJECTIVE: To ascertain the degree of agreement between a score for screening and another for diagnosis of motor development in 6-month old infants and to define the most appropriate cutoff point for screening. METHODS: A sectional study, enrolling asymptomatic full term newborns with gestational ages from 37 to 41 weeks, who were discharged from the maternity unit 2 days after birth and are resident in the Campinas area. Infants were excluded if they presented genetic syndromes, malformations, congenital infections, intensive care admission or low birth weight. The assessment instruments investigated were the Alberta Infant Motor Scale (AIMS) and the Bayley Scales of Infant Development II (BSID-II). Two cutoff points were evaluated for the AIMS, the 5th and 10th percentiles, and for the BSID-II infants were classified according to its motor index score (IS) as having inadequate (IS < 85, at least 1 standard deviation below the mean) or adequate performance (IS >or= 85, above the mean minus 1 standard deviation). RESULTS: The study sample comprised 43 infants. Six infants (14.00%) exhibited inadequate motor performance. Using the BSID-II motor classification and the 5th percentile AIMS cutoff, sensitivity was 100%, specificity 78.37%, accuracy 81.39%, kappa index 0.50 and p < 0.001; whereas, using the BSID-II motor classification and the 10th percentile AIMS cutoff, sensitivity was 100%, specificity 48.64%, accuracy 55.81%, kappa index 0.20 and p 0.025. CONCLUSIONS: The results suggest that concordance between the two 6-month assessment scales is good. The parameters employed are best combined using the 5th percentile AIMS cutoff point.

OBJETIVO: Verificar o grau de concordância entre uma escala de triagem e uma de diagnóstico do desenvolvimento motor de lactentes no sexto mês de vida, estabelecendo o ponto de corte mais apropriado para triagem. MÉTODOS: Estudo seccional, incluindo recém-nascidos a termo, com idade gestacional entre 37 e 41 semanas, assintomáticos, que receberam alta da maternidade 2 dias após o nascimento, residentes na região de Campinas. Foram excluídas síndromes genéticas, malformações, infecções congênitas, internações em unidade de terapia intensiva e baixo peso ao nascimento. Os instrumentos de avaliação foram: Alberta Infant Motor Scale (AIMS) e Bayley Scales of Infant Development II (BSID-II). Para a AIMS, foram utilizados dois pontos de corte, percentil 5 ou 10 e, para as BSID-II, foi utilizada a classificação dos lactentes na escala motora conforme a pontuação do index score (IS): desempenho inadequado (IS < 85, abaixo de menos 1 desvio padrão da média) ou desempenho adequado (IS > 85, maior ou igual a menos 1 desvio padrão da média). RESULTADOS: A amostra foi constituída por 43 lactentes. Seis lactentes (14,00 por cento) apresentaram desempenho motor inadequado. Considerando a classificação motora das BSID-II e o percentil 5 da AIMS, obteve-se sensibilidade = 100 por cento, especificidade = 78,37 por cento, acurácia = 81,39 por cento, índice kappa = 0,50 e p < 0,001; considerando a classificação motora das BSID-II e o percentil 10 da AIMS, obteve-se sensibilidade = 100 por cento, especificidade = 48,64 por cento, acurácia = 55,81 por cento, índice kappa = 0,20 e p = 0,025. CONCLUSÕES: Os resultados sugerem boa concordância entre os instrumentos de avaliação no sexto mês. A melhor combinação para os parâmetros analisados é a utilização do percentil 5 da AIMS.
