ABSTRACT

Abstract Introduction Individuals with autism spectrum disorder (ASD) have abnormalities in auditory perception and sensitivity. The mismatch negativity (MMN) component of the evoked potential demonstrates a brain detection response to an auditory change due to memory, and enables the identification of changes in the auditory system. Objectives To analyze MMN responses in children and adolescents with ASD and compare them with those of a control group. Methods Cross-sectional and comparative study. The sample was composed of 68 children and adolescents, divided into study group (SG), which contained those diagnosed with ASD, and the control group (CG), which contained those with typical development, normal hearing thresholds, and without hearing complaints. All participants were submitted to peripheral and central electrophysiological auditory evaluations. For the electrophysiological auditory evaluation and MMN recording, the electrodes were fixed in the following positions: Fz (active electrode), M1 and M2 (reference electrodes), and on the forehead (ground electrode). Auditory stimuli were presented in both ears simultaneously, with a frequency of 1,000 Hz for the frequent stimulus, and of 2,000 Hz for the rare stimulus, in an intensity of 80 dBNA. Results Latency and amplitude values were increased in the SG, with a statistically significant difference in comparison with the CG. In the MMN analysis, there was no statistically significant difference in the comparison between right and left ears and between genders. Conclusions Children and adolescents with ASD had higher latency and amplitude values in the MMN component than the individuals in the CG.

ABSTRACT

This research presents theoretical arguments of a new approach called Technique "K," which aims to reduce student's anxiety before a cognitive challenge. Through a randomized, controlled clinical trial, we evaluate the Beck Anxiety Inventory and salivary cortisol. We compared the results in the last year of high school, who were facing school tests, before and after the application of the "K" technique (intervention group) and placebo (control group). Statistical analyses consisted of using the Chisquare, Spearman and the Wilcoxon test. The principal component analysis observed in the case group, - 10.50 (-18.25; -4.75), was statistically higher than the control group, -6.00 (-8.75; -1.25). It is not possible to identify statistical significance (p = 0.462) in the variation of salivary cortisol concentration. The results suggest the effectiveness of the "K" technique in managing anxiety in high school students. Although, future research is needed to extend the preliminary data obtained in this study


Esta pesquisa apresenta argumentos teóricos de uma nova abordagem denominada Técnica "K", visando reduzir a ansiedade do aluno diante de um desafio cognitivo. Por meio de um ensaio clínico randomizado e controlado, avaliamos o Inventário de Ansiedade de Beck e o cortisol salivar. Comparamos os resultados dos alunos, que estavam enfrentando provas escolares, antes e após a aplicação da técnica "K" (grupo intervenção) e placebo (grupo controle). As análises estatísticas consistiram na utilização do Qui-quadrado, Spearman e teste de Wilcoxon. A análise de componentes principais observada no grupo caso, -10,50 (-18,25; -4,75), foi estatisticamente superior ao grupo controle, -6,00 (-8,75; -1,25). Não é possível identificar significância estatística (p = 0,462) na variação da concentração de cortisol salivar. Os resultados sugerem a eficácia da técnica "K" no manejo da ansiedade em estudantes do ensino médio. No entanto, pesquisas futuras são necessárias para estender os dados preliminares obtidos neste estudo

A través de un ensayo clínico aleatorizado y controlado, evaluamos el Inventario de Ansiedad de Beck y el cortisol salival. Comparamos los resultados de los estudiantes, que se enfrentaban a pruebas escolares, antes y después de la aplicación de la técnica "K" (grupo de intervención) y placebo (grupo control). Los análisis estadísticos consistieron en utilizar la prueba de Chicuadrado, Spearman y Wilcoxon. El análisis de componentes principales observado en el grupo de casos, -10,50 (-18,25; -4,75), fue estadísticamente superior al grupo control, -6,00 (-8,75; -1,25). No es posible identificar significación estadística (p = 0,462) en la variación de la concentración de cortisol salival. Los resultados sugieren la efectividad de la técnica "K" en el manejo de la ansiedad en estudiantes de secundaria. Sin embargo, se necesitan futuras investigaciones para ampliar los datos preliminares obtenidos en este estudio

ABSTRACT

Abstract Purpose: This study aimed to analyze the auditory processing behavior of children and adolescents diagnosed with stroke and compare it with that of typically developing individuals. Methods: This was an analytical cross-sectional study involving 48 participants aged between 7 and 17 years with adequate schooling for age and grade, allocated equally to two groups: Stroke (SG) and Control Groups (CG). For the SG, cases identified between 2003 and 2018 were considered. In the CG, school-aged participants with typical development were randomized. After screening for differential audiological assessment and confirmation of auditory pathway integrity at the brainstem level, binaural analyses of the auditory processing behavior were conducted using the Dichotic Digit Test (DDT), Frequency Pattern Test (FPT), and electrophysiological assessment (P300). The Shapiro-Wilk test for normality was conducted, followed by the T and Mann-Whitney tests, with a 95 % confidence level and significance offset at p < 0.05, using the SPSS software (IBM®, v. 22.) Results: The CG performed better in terms of auditory processing. These differences were significant (p < 0.0001) for the binaural integration of DDT, FPT humming and Labeling, and P300 latency. The P300 results were similar; however, with a greater amplitude in the SG. Conclusion: This study showed that children and adolescents with stroke performed worse in electrophysiological and behavioral tests of auditory processing assessed using the auditory evoked potentials. These data reinforce the hypothesis that stroke-related lesions compromise the neural mechanisms underlying auditory processing.

ABSTRACT

OBJECTIVES: To analyze central auditory maturation in term and preterm infants during the first 3 months of life by comparing the latency and amplitude of cortical auditory-evoked potential at different frequencies. METHODS: In this study, 17 term and 18 preterm infants were examined; all had tested positive on the neonatal hearing screening test. Cortical auditory potential was investigated during the first and third months of life. The response of the cortical auditory-evoked potential was investigated at frequencies of 500, 1000, 2000, and 4000 Hz. The latency and amplitude of the cortical response were automatically detected and manually analyzed by three researchers with experience in electrophysiology. The results were compared using analysis of variance and the Bonferroni test. A significance level of 5% was used for all analyses. RESULTS: Latency values of cortical auditory-evoked potential in the first month of birth were significantly higher than those in the third month, and latency values of the preterm group were higher than those of the term group, regardless of the frequency and time of evaluation. In general, the latency of the cortical auditory-evoked potential was higher at high frequencies. Amplitude values in the third month of life were significantly higher than those in the first month for term and preterm infants. CONCLUSION: Central auditory maturation was observed in both groups but with different results between those born at term and preterm, with latencies of cortical auditory-evoked potential higher for the preterm group and at high frequencies.

ABSTRACT

Abstract Objectives: To measure the prevalence of vitamin D deficiency (through the 25-hydroxyvitamin D metabolite) in pediatric patients using antiepileptic drugs. Source of data: Meta-analysis of studies identified through search in the PubMed, Embase, LILACS, and Cochrane Library databases, on February 19, 2019. Summary of data: A total of 748 articles were identified, 29 of which were relevant to the objectives of this study. The prevalence of vitamin D deficiency found was 0.32 (95% CI = 0.25-0.41; I 2 = 92%, p < 0.01). In the subgroup analyses, the most significant results were observed in the group of patients using cytochrome P450-inducing antiepileptic drugs, with a prevalence of 0.33 (95% CI = 0.21-0.47; I 2 = 86%, p < 0.01) and, considering the study design, in the subgroup of cohort studies, with a prevalence of 0.52 (95% CI = 0.40-0.64; I 2 = 76%, p < 0.01). Conclusions: Taking into account the deleterious effects of vitamin D deficiency on the bone health of individuals using antiepileptic drugs, it is suggested to include in their care 25-hydroxyvitamin D monitoring, cholecalciferol supplementation, and treatment of the deficiency, when present.

ABSTRACT

Abstract Introduction: The study of the threshold level of cortical auditory response in adults has been investigated in previous studies. Due to maturational issues, little is known about these responses in neonates. Technological advances with automatic analysis devices now allow investigation in specific populations. Thus, new studies are needed to establish the feasibility of using this auditory potential to identify the lowest levels of responses in children. Objective: Verify and compare latency and amplitude in 80 dBnNA and the minimum level of cortical auditory response in term and preterm neonates. Methods: A cross-sectional, comparative study involving 59 neonates, 35 full-term births and 24 preterm births, with positive results in the Neonatal Hearing Screening. The Hearlab system was used to investigate the P1i auditory potential with tone burst stimulus at frequencies of 500, 1000, 2000 and 4000 Hz. The minimum response level search ranged from 80 to 0 dBNA and was detected automatically. The results were compared between groups, evaluating the latency and amplitude in 80 dBNA and the minimum level of cortical auditory response. Results: The mean values obtained for the minimum level of cortical auditory response in term group were 26 ± 8.81; 26.14 ± 6.97; 29 ± 7.65 and 29.43 ± 7.04 dBNA and for preterm neonates of 31.96 ± 10.41; 34.13 ± 11.34; 33.64 ± 11.03 and 37.73 ± 11.92 dBNA, for the frequencies of 500, 1000, 2000 and 4000 Hz, respectively. There was a difference between groups for the latency of P1i at 4000 Hz and the minimum response levels at 500, 1000 and 4000 Hz, with higher values for preterm infants. Conclusion: It was possible to obtain latency and amplitude values at 80 dBnNA and the minimum level of cortical response in term and preterm newborns, with different results between groups, with higher values in those born preterm.


Resumo Introdução: A investigação do nível mínimo de resposta auditiva cortical tem sido alvo de diferentes estudos em adultos. Devido a questões de maturação, pouco se sabe sobre essas respostas em recém-nascidos. Com o avanço tecnológico, dispositivos de análise automática surgiram com o objetivo de retomar essa avaliação em populações específicas. Assim, novos estudos são necessários para verificar a viabilidade do uso desse potencial auditivo na obtenção de níveis mínimos de respostas na criança. Objetivo: Verificar e comparar latência e amplitude em 80 dBnNA e o nível mínimo de resposta auditiva cortical em recém-nascidos a termo e pré-termo. Método: Estudo transversal, comparativo, envolvendo 59 neonatos, 35 nascidos a termo e 24 pré-termos, com resultados positivos na triagem auditiva neonatal. O sistema Hearlab foi utilizado para investigar o potencial auditivo P1i com estímulo tone burst nas frequências de 500, 1000, 2000 e 4000 Hz. A busca do nível mínimo de resposta variou de 80 a 0 dBNA e foi detectado automaticamente. Os resultados foram comparados entre os grupos, avaliando a latência e amplitude em 80 dBNA e o nível mínimo de resposta auditiva cortical. Resultados: Os valores médios obtidos para o nível mínimo de resposta auditiva cortical no grupo nascido a termo foram 26 ± 8,81; 26,14 ± 6,97; 29 ± 7,65 e 29,43 ± 7,04 dBNA e para recém-nascidos pré-termos foram de 31,96 ± 10,41; 34,13 ± 11,34; 33,64 ± 11,03 e 37,73 ± 11,92 dBNA, para as frequências de 500, 1000, 2000 e 4000 Hz, respectivamente. Houve diferenc¸a entre os grupos para a latência de P1i em 4000 Hz e os níveis mínimos de resposta em 500, 1000 e 4000 Hz, com valores maiores em Pré-termos. Conclusão: Foi possível obter valores de latência e amplitude em 80 dBnNA e o nível mínimo de resposta cortical em recém-nascidos a termo e Pré-termos, com resultados diferentes entre osgrupos, com valores maiores em pré-termos.

ABSTRACT

SUMMARY The increase in bilirubin levels in newborns can cause toxic effects on the auditory system, which can lead to hearing loss. This review aimed to verify the impact of hyperbilirubinemia in the hearing of newborns, relating audiological findings to serum levels of bilirubin. A literature review was conducted during October 2017, using the terms "hyperbilirubinemia", "jaundice", "infant", "newborn" and "hearing loss", on databases CAPES journals, MEDLINE and BIREME (SciELO, BBO). 827 studies were identified and 59 were selected for full-text reading, resulting in the selection of seven articles that met the inclusion criteria and were considered relevant to the sample of this study. All the reviewed studies performed brainstem auditory evoked potential as the main test for audiological evaluation. Changes in the audiological findings of neonates with hyperbilirubinemia were observed in all studies. There was no consensus on the serum bilirubin levels that may cause auditory changes; however, the relationship between hearing disorders and blood levels of bilirubin was positive. We identify the need to establish reference values for bilirubin levels considered critical for the occurrence of hearing disorders as well as the audiological follow-up of neonates with hyperbilirubinemia.


RESUMO O aumento nos níveis de bilirrubina no neonato pode provocar efeitos tóxicos no sistema auditivo, podendo levar à perda auditiva. O objetivo desta revisão foi verificar o impacto da hiperbilirrubinemia na audição de recém-nascidos, relacionando os achados audiológicos aos níveis séricos de bilirrubina. Realizou-se uma revisão sistemática de literatura durante o mês de outubro de 2017, utilizando-se os termos hyperbilirubinemia, jaundice, infant, newborn e hearing loss, nas bases de dados periódicos Capes, Medline e Bireme (SciELO, BBO). Foram identificados 827 estudos, dentre os quais 59 foram selecionados para leitura do texto na íntegra, resultando na seleção de sete artigos que atendiam aos critérios de inclusão e foram considerados relevantes para a amostra deste trabalho. Em todas as pesquisas revisadas, o potencial evocado auditivo de tronco encefálico foi o principal exame audiológico realizado. Em todos os estudos foram observadas alterações nos resultados audiológicos de neonatos com hiperbilirrubinemia. Não houve consenso quanto aos níveis séricos de bilirrubina que podem causar alterações auditivas, porém, a relação entre as alterações audiológicas e os níveis sanguíneos de bilirrubina foi positiva. Percebeu-se a necessidade de estabelecer valores de referência para os níveis de bilirrubina considerados críticos para a ocorrência de alterações audiológicas, assim como de acompanhamento audiológico dos neonatos com hiperbilirrubinemia.

ABSTRACT

RESUMO O objetivo deste estudo foi avaliar a qualidade de vida (QV) de crianças/adolescentes com diagnóstico de acidente vascular cerebral (AVC) segundo as percepções do responsável e das próprias crianças/adolescentes comparados com um grupo controle (GC). Participaram 78 sujeitos divididos em: Grupo de crianças/adolescentes que tiveram histórico de AVC (GAVC, n=39) e um Grupo de crianças/adolescentes saudáveis como Controle (GC, n=39), sendo pareados por sexo e idade. Utilizou-se de entrevista semiestruturada para descrever os aspectos sociodemográficos e do instrumento Pediatric Quality of Life Inventory (PedsQLTM 4.0) para avaliar a QV dos sujeitos no seu desenvolvimento. A mediana de idade do diagnóstico de AVC do GAVC foi sete meses, sendo que a maioria apresentou AVC isquêmico (71,8%) e hemiparesia. De acordo com os responsáveis do GAVC, a Capacidade Funcional dos seus filhos foi significativamente diferente, apresentando inferioridade em relação ao GC. Para os responsáveis também a variável escolaridade do pai manteve efeito positivo significativo nos aspectos emocionais da criança, e a variável idade da criança/adolescente e tempo do AVC >29 dias de vida apresentou efeito negativo nos aspectos escolares. Já para as crianças/adolescentes, a variável idade em que entrou na escola e gênero apresentou efeito significativo negativo no desfecho de aspectos escolares em relação ao GC. Concluímos que a percepção dos responsáveis difere da percepção da criança/adolescente em relação à capacidade funcional desta; a escolaridade do pai influenciou positivamente nos aspectos emocionais da criança, e as crianças sentem-se com um prejuízo no desempenho escolar, principalmente os meninos.


RESUMEN El objetivo de este estudio ha sido evaluar la cualidad de vida (CV) de niños/adolescentes con diagnóstico de ataque cerebrovascular (ACV), según las percepciones del responsable y de los propios niños/adolescentes comparados con un grupo control (GC). Han participado 78 sujetos divididos en: Grupo de niños/adolescentes que han tenido histórico de ACV (GACV, n=39) y un Grupo de niños/adolescentes saludables como Control (GC, n=39), siendo pareados por sexo y edad. Se ha utilizado de encuesta semiestructurada para describir los aspectos sociodemográficos y del instrumento Pediatric Quality of Life Inventory (PedsQLTM 4.0) para evaluar la CV de los sujetos en su desarrollo. El promedio de edad del diagnóstico de ACV del GACV ha sido siete meses, siendo que la gran parte ha presentado ACV isquémico (el 71,8%) y hemiparesia. De acuerdo con los responsables del GACV, la Capacidad Funcional de sus hijos ha sido significativamente, distinta, presentando inferioridad en relación al GC. Para los responsables también la variable escolaridad del padre ha mantenido el efecto positivo significativo en los aspectos emocionales del niño, y la variable edad del niño/adolescente y tiempo del ACV >29 días de vida ha presentado el efecto negativo en los aspectos escolares. Ya para los niños/adolescentes, la variable edad en que ha ingresado a la escuela y el género ha presentado efecto significativo negativo en el desfecho de aspectos escolares en relación al GC. Hemos concluido que la percepción de los responsables difiere de la percepción del niño/adolescente en relación a la capacidad funcional de esta; la escolaridad del padre ha influenciado positivamente en los aspectos emocionales del niño, y los niños se sienten con un perjuicio en el desempeño escolar, principalmente los niños.


ABSTRACT The aim of this study was to evaluate the quality of life (QoL) of children/adolescents with a diagnosis of stroke (CVA) in the eyes of the person responsible and the children / adolescents themselves compared to a control group. 78 subjects were divided into: Group of children / adolescents who had a history of stroke (GAVC, n = 39) and a group of healthy children/adolescents as Control (CG, n = 39) matched by gender and age. A semi-structured interview was used to describe the sociodemographic aspects and the Pediatric Quality of Life Inventory (PedsQLTM 4.0) to evaluate the QoL of the subjects in their development. The median age of the diagnosis of stroke was 7 months, with the majority presenting ischemic stroke (71.8%) and hemiparesis.According to those responsible for the GAVC, the Functional Capacity of their children was significantly different, presenting inferiority in relation to the CG. Also, for those in charge, the father's educational variable maintained a significant positive effect on the emotional aspects of the child, and the variable age of the child /adolescent and stroke time> 29 days of life had a negative effect on the school aspects. As for the children / adolescents, the variable age that entered school and gender had a significant negative effect on the outcome of school aspects in relation to the CG. We conclude that the view of those responsible differs from the child/adolescent's view of their functional capacity; the father's schooling positively influenced the emotional aspects of the child and the children feel a loss in school performance, especially the boys.

ABSTRACT

RESUMO Objetivo O objetivo desse estudo foi comparar a latência e amplitude do potencial evocado auditivo cortical P1i entre neonatos em estado de alerta e durante o sono leve. Métodos Vinte e cinco neonatos com emissões otoacústicas evocadas transientes presentes foram testados, por meio do potencial evocado auditivo cortical (PEAC), sendo dez em estado de alerta e 15 durante o sono leve. Para pesquisa dos potenciais corticais, utilizou-se o equipamento Hearlab System, de um canal, no módulo Cortical Tone Evaluation (CTE). O potencial P1i foi pesquisado de forma monoaural, na intensidade de 80 dBnNA, para as frequências de 500, 1000, 2000 e 4000Hz. A detecção do P1i foi feita de maneira automática pelo equipamento. A marcação da latência e amplitude foi realizada por três juízes. Resultados Não houve diferença estatisticamente significativa entre os dois grupos de neonatos para os valores de amplitude e latência, nas quatro frequências testadas. Conclusão Não houve influência do estado comportamental dos neonatos na avaliação do potencial cortical P1i.


ABSTRACT Purpose The aim of the present study was to compare latency and amplitude of the cortical auditory evoked response P1i among newborns in an alert state and during light sleep. Methods Twenty-five neonates with normal transient evoked otoacoustic emissions were tested with cortical auditory evoked potentials (CAEP): 10 were in an alert state and 15 in light sleep during testing. For the investigation of cortical potentials, a single-channel Hearlab System equipment, Cortical Tone Evaluation module (CTE), was used. The P1i potential was investigated monoaurally at an 80dBnHL intensity at 500, 1000, 2000 and 4000 Hz. P1i was automatically detected by the equipment. Latency and amplitude were marked by three judges. The responses of the newborn in an alert state were compared with those in light sleep. Results There was no statistically significant difference between the two groups of neonates for the amplitude and latency values at the four tested frequencies. Conclusion There was no influence of the neonates' behavioral state on the evaluation of the P1i auditory cortical potential.

ABSTRACT

Abstract Introduction The tone-evoked auditory brainstem responses (tone-ABR) enable the differential diagnosis in the evaluation of children until 12 months of age, including those with external and/or middle ear malformations. The use of auditory stimuli with frequency specificity by air and bone conduction allows characterization of hearing profile. Objective The objective of our study was to compare the results obtained in tone-ABR by air and bone conduction in children until 12 months, with agenesis of the external auditory canal. Method The study was cross-sectional, observational, individual, and contemporary. We conducted the research with tone-ABR by air and bone conduction in the frequencies of 500 Hz and 2000 Hz in 32 children, 23 boys, from one to 12 months old, with agenesis of the external auditory canal. Results The tone-ABR thresholds were significantly elevated for air conduction in the frequencies of 500 Hz and 2000 Hz, while the thresholds of bone conduction had normal values in both ears. We found no statistically significant difference between genders and ears for most of the comparisons. Conclusion The thresholds obtained by bone conduction did not alter the thresholds in children with conductive hearing loss. However, the conductive hearing loss alter all thresholds by air conduction. The tone-ABR by bone conduction is an important tool for assessing cochlear integrity in children with agenesis of the external auditory canal under 12 months.

ABSTRACT

Abstract Objective: To evaluate the safety, tolerability and potential therapeutic effects of gastrin-releasing peptide in three children with autistic spectrum disorder. Methods: Case series study with the intravenous administration of gastrin-releasing peptide in the dose of 160 pmol/kg for four consecutive days. To evaluate the results, parental impressions the Childhood Autism Rating Scale (CARS) and the Clinical Global Impression (CGI) Scale. Each child underwent a new peptide cycle after two weeks. The children were followed for four weeks after the end of the infusions. Results: The gastrin-releasing peptide was well tolerated and no child had adverse effects. Two children had improved social interaction, with a slight improvement in joint attention and the interaction initiatives. Two showed reduction of stereotypes and improvement in verbal language. One child lost his compulsion to bathe, an effect that lasted two weeks after each infusion cycle. Average reduction in CARS score was 2.8 points. CGI was "minimally better" in two children and "much better" in one. Conclusions: This study suggests that the gastrin-releasing peptide is safe and may be effective in improving key symptoms of autism spectrum disorder, but its results should be interpreted with caution. Controlled clinical trials-randomized, double-blinded, and with more children-are needed to better evaluate the possible therapeutic effects of gastrin-releasing peptide in autism.


Resumo Objetivo: Avaliar a segurança, a tolerabilidade e os possíveis efeitos terapêuticos do peptídeo liberador de gastrina em três crianças com transtorno do espectro autista. Métodos: Estudo de casuística com administração intravenosa de peptídeo liberador de gastrina na dose de 160 pmol/kg por quatro dias consecutivos. Para avaliar os resultados, foram usadas a impressão dos pais, a Escala de Classificação de Autismo na Infância (CARS) e a Escala de Impressão Clínica Global (CGI). Cada criança foi submetida a novo ciclo de peptídeo após duas semanas. As crianças foram acompanhadas por quatro semanas após o término das infusões. Resultados: O peptídeo liberador de gastrina foi bem tolerado e nenhuma criança apresentou efeitos adversos. Duas crianças apresentaram melhoria na interação social, com melhoria na atenção compartilhada e nas iniciativas de interação. Duas mostraram redução dos estereótipos e melhoria na linguagem verbal. Uma criança perdeu sua compulsão por banhos, efeito que durou duas semanas após cada ciclo de infusão. A redução média no escore da CARS foi de 2,8 pontos. Quanto à CGI, os resultados foram "minimamente melhor em duas crianças" e "muito melhor" em uma. Conclusões: Este estudo sugere que o peptídeo liberador de gastrina é seguro e pode ser efetivo na melhoria dos principais sintomas do transtorno do espectro autista, porém seus resultados devem ser interpretados com cautela. Ensaios clínicos controlados, randomizados, duplo-cegos e com maior número de crianças são necessários para melhor avaliar os possíveis efeitos terapêuticos do peptídeo liberador de gastrina sobre o autismo.

ABSTRACT

Abstract

Human T cell lymphotropic virus type 1 (HTLV-1)-associated infective dermatitis (ID) is a chronic, severe and recurrent eczema occurring during childhood in patients vertically infected with HTLV-1. HTLV-1-associated myelopathy/tropical spastic paraparesia (HAM/ TSP) is slow and progressive. We report the case of an adolescent female from a non-endemic area for HTLV-1 who presents ID and, most likely, associated HAM/TSP.

ABSTRACT

The literature has shown a strong relationship between executive dysfunction and Autism Spectrum Disorder (ASD), although there is no consensus on which subprocesses of executive functioning are impaired and/or preserved in this condition. This study aimed to investigate executive function and working memory in children and adolescents with ASD (n = 11) compared to children and adolescents with typical development (n = 19) matched by age, formal education, and nonverbal IQ. The tests used were: Raven’s Colored Progressive Matrices, Stroop Test, Trail Making Test, Rey’s Complex Figure Test, Digit span, Pseudowords span, Working memory, Verbal fluency (orthographic and semantic) and Go/no go. The results demonstrate impairment of executive function in the clinical group, especially in planning, flexibility, inhibition, and also visuospatial working memory.


A literatura tem demonstrado uma forte relação entre disfunções executivas e Transtorno do Espectro do Autismo (TEA), apesar de ainda não haver consenso sobre quais subprocessos do funcionamento executivo encontram-se prejudicados e/ou preservados nessa condição. Esse estudo teve por objetivo avaliar as funções executivas e a memória de trabalho em crianças/adolescentes com TEA (n = 11), comparadas a crianças/adolescentes com desenvolvimento típico (n = 19), equiparadas por idade, anos completos de estudo formal e QI não-verbal. Os testes usados foram: Matrizes Progressivas Coloridas de Raven, Teste Stroop, Teste de Trilhas, Figuras Complexas de Rey, Span de Dígitos, Span de Pseudopalavras, Memória de trabalho visuoespacial, Fluência verbal (ortográfica e semântica) e Go/no go. Os resultados demonstram prejuízos de funções executivas no grupo clínico, em especial na capacidade de planejamento, flexibilidade cognitiva, inibição, além do componente visuoespacial da memória de trabalho.

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

OBJECTIVE: To translate into Brazilian Portuguese the Autism Diagnostic Interview-Revised (ADI-R), an extremely useful diagnostic tool in autism. METHODS: A case-control study was done to validate the ADI-R. After being translated, the interview was applied in a sample of 20 patients with autism and 20 patients with intellectual disability without autism, in order to obtain the initial psychometric properties. RESULTS: The internal consistency was high, with a of Crombach of 0.967. The validity of criterion had sensitivity and specificity of 100 percent, having as a gold standard the DSM-IV diagnostic criteria. The interview had high discriminant validity, with higher scores in the group of patients with autism, as well as high interobserver consistency, with median kappa of 0.824. CONCLUSION: The final version of ADI-R had satisfactory psychometric characteristics, indicating good preliminary validation properties. The instrument needs to be applied in bigger samples in other areas of the country.


OBJETIVO: Traduzir para o português do Brasil a ADI-R (Autism Diagnostic Interview-Revised), uma ferramenta diagnóstica extremamente útil em casos de autismo. MÉTODOS: Foi realizado um estudo caso-controle para validar a ADI-R. A fim de se obter as propriedades psicométricas iniciais da entrevista, após a tradução, a ADI-R foi aplicada em uma amostra de 20 pacientes com autismo e 20 controles com retardo mental sem autismo. RESULTADOS: A consistência interna foi alta, com um a de Crombach de 0,976. A validade de critério mostrou uma sensibilidade e uma especificidade de 100 por cento, tendo os critérios diagnósticos do DSM-IV como padrão ouro. A entrevista teve uma alta validade discriminante, com maiores escores no grupo de pacientes com autismo, bem como uma alta consistência entre observadores, com um Kappa médio de 0,824. CONCLUSÃO: A versão final da ADI-R teve características psicométricas satisfatórias, indicando boas propriedades preliminares de validação. O instrumento necessita ser aplicado em amostras maiores em outras áreas do país.

ABSTRACT

OBJETIVO: Alertar a comunidade pediátrica às consequências neurológicas da toxocaríase e descrever o primeiro caso pediátrico de neurotoxocaríase com acometimento simultâneo do cérebro, cerebelo e sistema nervoso periférico. DESCRIÇÃO: Relatamos um caso de neurotoxocaríase em criança do sexo masculino, 5 anos de idade, previamente hígido, com sintomas incomuns e acometimento multifocal dos sistemas nervosos central e periférico. Discutimos o diagnóstico diferencial e fazemos uma breve revisão da literatura. Desde o início da década de 1950, menos de 50 casos de neurotoxocaríase foram descritos, a maioria em adultos. COMENTÁRIOS: A toxocaríase é uma das helmintíases mais comuns em humanos. A neurotoxocaríase, porém, é uma patologia rara, especialmente na população pediátrica. Embora a toxocaríase costume seguir um curso autolimitado, sem envolvimento do sistema nervoso central, as manifestações neurológicas podem ser devastadoras quando ocorrem. A neurotoxocaríase deve fazer parte do diagnóstico diferencial de pacientes pediátricos com sintomas neurológicos atípicos e eosinofilia no líquor. Se diagnosticada e tratada precocemente, é possível evitar as sequelas neurológicas a longo prazo.


OBJECTIVES: To alert pediatricians to the neurologic consequences of toxocariasis and to describe the first pediatric case of neurotoxocariasis with concomitant cerebral, cerebellar and peripheral nervous system involvement. DESCRIPTIONS: We report a case of neurotoxocariasis in a previously healthy 5-year-old boy with unusual symptoms and multi-site involvement of both the central and peripheral nervous system. Differential diagnoses are discussed and the relevant literature is reviewed. Since the early 1950s, fewer than fifty cases have been described, mostly in adult patients. COMMENTS: Although human toxocariasis is one of the most common zoonotic helminth infections, neurotoxocariasis is a rare condition, especially in pediatric patients. Although toxocariasis usually presents as a self-limiting disease with no central nervous system involvement, when it does occur, it can be devastating. Neurotoxocariasis should be added to the differential diagnosis of pediatric patients with unusual neurologic symptoms accompanied by high levels of eosinophils in the cerebrospinal fluid. Early diagnosis and treatment can prevent long-term neurologic sequelae.

ABSTRACT

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...


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...
