OBJETIVO: Verificar a habilidade de atenção seletiva em crianças com acidente vascular cerebral (AVC). MÉTODOS: Foram aplicados testes dicóticos de separação (não verbal e consoante-vogal) e integração - dígitos e Staggered Spondaic Words Test (SSW) - binaural em 13 crianças (7 meninos), entre 7 e 16 anos, com AVC unilateral confirmado por neuroimagem. RESULTADOS: O desempenho atencional diferiu entre os grupos na realização de ambos os tipos de tarefa. Ao teste não verbal, houve menor quantidade de identificações com a orelha contralateral à lesão em atenção livre e dificuldade de focalizar a atenção nas etapas direcionadas. No teste consoante-vogal, houve modificação da assimetria perceptual e dificuldade de focalizar a atenção nas etapas direcionadas. Nos testes de dígitos e SSW, foram constatados défices ipsilaterais, contralaterais e bilaterais dependendo das características da lesão e da demanda da tarefa. CONCLUSÃO: As crianças com AVC apresentaram défices na habilidade de atenção seletiva em presença de fontes simultâneas de informação auditiva verbal e não verbal.

OBJECTIVE: To verify the auditory selective attention in children with stroke. METHODS: Dichotic tests of binaural separation (non-verbal and consonant-vowel) and binaural integration - digits and Staggered Spondaic Words Test (SSW) - were applied in 13 children (7 boys), from 7 to 16 years, with unilateral stroke confirmed by neurological examination and neuroimaging. RESULTS: The attention performance showed significant differences in comparison to the control group in both kinds of tests. In the non-verbal test, identifications the ear opposite the lesion in the free recall stage was diminished and, in the following stages, a difficulty in directing attention was detected. In the consonant- vowel test, a modification in perceptual asymmetry and difficulty in focusing in the attended stages was found. In the digits and SSW tests, ipsilateral, contralateral and bilateral deficits were detected, depending on the characteristics of the lesions and demand of the task. CONCLUSION: Stroke caused auditory attention deficits when dealing with simultaneous sources of auditory information.

TEMA: na infância a doença cerebrovascular (DCV) constitui condição rara em que a evolução a curto, médio e longo prazo tem merecido esclarecimentos. Neste sentido, a aplicação de técnicas comportamentais pode possibilitar melhor caracterização clínica, visando o planejamento e controle terapêutico eficientes. OBJETIVO: descrever em uma criança com DCV as manifestações audiológicas em dois momentos distintos da evolução clínica. MÉTODO: a criança, com diagnóstico comprovado de episódio único e unilateral de DCV, apresentando habilidades de linguagem e cognição satisfatórias, foi submetida a conjunto de testes convencionais e de processamento auditivo, incluindo a avaliação simplificada e as categorias de testes monóticos, dicóticos e de processamento temporal. Os dados obtidos foram pareados com criança normal destra, de mesmo sexo, idade e nível sócio-cultural. RESULTADOS: foi constatado comprometimento nas habilidades de memória auditiva e atenção seletiva em tarefas de integração e separação binaural para estímulos verbais e não-verbais. CONCLUSÃO: a evolução, embora favorável, se mostrou abaixo do esperado para a idade, quando comparado com seu par. A avaliação prospectiva da criança acometida por DCV possibilitou caracterizar o comportamento auditivo, definir seus parâmetros e a evolução do quadro audiológico.

BACKGROUND: cerebrovascular disease (CVD) during childhood is a rare condition; its short, medium and long-term characteristics deserve further investigation. The application of behavioral techniques may improve clinical characterization, thus rendering more efficient therapeutic planning and control. AIM: to describe the audiological manifestations in a child with CVD in two distinct moments of clinical follow-up. METHOD: the child, with a confirmed diagnosis of a single and unilateral episode of CVD, presenting satisfactory cognition and language skills, was submitted to a battery of conventional and auditory processing tests, which included a simplified evaluation as well as monotic, dichotic, and temporal processing tests. The obtained data was paired with those of a normal right-handed child, of the same gender, age and socio-cultural level. RESULTS: results indicate impairments in auditory memory as well as in selective attention during binaural separation and integration tasks for verbal and non-verbal stimuli. CONCLUSION: clinical development, although favorable, was below the average expected for the same age when compared to the control. The prospective evaluation of a child with DCV permitted the characterization of the auditory behavior, the definition of its parameters as well as the development of the audiological characteristics.

This study investigated possible prenatal and neonatal variables that may influence the prevalence of tooth enamel hypoplasia in preterm and low birth weight children (LBW) and a matched control group of term children with normal birth weight (NBW). The study sample consisted of 61 children born preterm and with LBW examined at 18-34 months of age. The control group was formed by 61 infants born full term and with NBW examined at 31-35 months of age. All children were born at the Center of Integrated Attention of Women's Health (CAISM-UNICAMP). FDI criteria were followed for dental examination. Medical data was collected retrospectively from hospital records. Among preterms, 57.4% had some type of developmental defects of enamel (DDE), 52.5 % had opacities and 21.3 % presented hypoplasia. Among full-term children, 24.6% presented DDE, 24.6% had opacities and 3.3% had hypoplasia. LBW preterm infants presented a higher prevalence of hypoplasia than NBW controls. The deciduous teeth most affected by hypoplasia were maxillary incisors. There was no significant association with prenatal variables; among neonatal variables there was a significant association with respiratory distress syndrome and neurological examination at discharge with an altered result.

O objetivo deste estudo foi avaliar e comparar o neurodesenvolvimento de lactentes nascidos a termo, com peso adequado (AIG) ou pequeno para a idade gestacional (PIG), no 2º mês de vida. Avaliaram-se 67 lactentes: 43 AIG e 24 PIG, utilizando as Bayley Scales of Infant Development. O Index Score (IS) nas Escalas Mental e Motora foi significativamente menor no grupo PIG. Considerando a proporcionalidade corporal (Grupos Controle, Assimétrico e PIG-Simétrico), houve diferença significativa na Escala Motora (p=0,003), com menores pontuações no grupo PIG-Simétrico. Comparados aos percentis de IS do grupo Controle, na Escala Mental, houve diferença entre os grupos Assimétrico X PIG-Simétrico; na Escala Motora, houve diferença entre os grupos Assimétrico X Controle (p=0,039) e PIG-Simétrico X Controle (p=0,0007); não houve diferença entre os grupos Assimétrico e PIG-Simétrico, ambos apresentando menores pontuações que o grupo Controle.

The objective of the present study was to assess and to compare the neurodevelopment of full-term adequate (AGA) or small-for-gestational age (SGA) infants in the second month of life. Sixty-seven infants were evaluated: 43 AGA and 24 SGA, making use of the Bayley Scales of Infant Development. The SGA group Index Score (IS) was significantly lower in Mental and Motor Scales. Considering the body proportionality (Asymmetric, Symmetric-SGA and Control group) there was difference in Motor Scale (p=0.003) with lower scores in the Symmetric-SGA group. Comparing to the Control group IS percentiles, in Mental Scale there was difference between Asymmetric X Symmetric-SGA; in Motor Scale, there was difference between the Asymmetric X Control (p=0.039) and Symmetric-SGA X Control (p=0.007) groups; there was no difference between Asymmetric and Symmetric-SGA although both exhibited lower scores than the Control group.

São descritas duas crianças, uma com idade cronológica de 5 anos e 6 meses e outra com 5 anos e 10 meses. Ambas apresentaram doença cerebrovascular (DCV) bilateral, confirmada na fase aguda através de exame neurológico clínico e de imagem. Os dois pacientes foram atendidos nesta fase por médico neurologista infantil da Disciplina de Neurologia Infantil da FCM/UNICAMP, ambulatório de DCV na infância. Nas avaliações utilizou-se Triagem Audiológica, Protocolo de Avaliação da Linguagem Infantil, Teste de Vocabulário por Imagens Peabody, com o objetivo de avaliar os diversos subsistemas lingüísticos e as noções perceptiva-cognitivas. Na análise qualitativa dos dois sujeitos, do ponto de vista fonoaudiológico e neurológico, houve recuperação completa do distúrbio adquirido de linguagem para o primeiro e alterações sutis no posterior processo de aprendizagem do segundo. O estudo dos casos revelou que os aspectos predominantes devem ser analisados de forma individual, quantitativa e qualitativamente para achados conclusivos.

We describe two children, aging 5 years and 6 months and 5 years and 10 months respectively, when the phonoaudiological assessment was conducted. Both children presented bilateral cerebrovascular disease (CVD), confirmed in the acute phase by means of clinical and image neurological test. During this phase, the two patients were examined by a pediatric neurologist of the Pediatric Neurology Discipline of FCM/UNICAMP, pediatric CVD ambulatory. Audiologic Assessment, Protocol for Infant Language Assessment, and Peabody Picture Vocabulary Test were used in the evaluations. The qualitative analysis of the two subjects from a phonoaudiological and neurological point of view has shown the recovery of adquired languague disturbance with no influence whatsoever in the development of the first subject and subtle language and/or learning process alterations for the second subject. The cases study has revealed that the predominant aspects should be analyzed in an individual, quantitative, and qualitative basis to lead to conclusive findings.

Foram estudadas 175 crianças com paralisia cerebral hemiparética (PC-H) para elucidar o período de risco etiológico. Através da anamnese constataram-se fatores de risco para etiologia (FRE) pré-natal em 23%, perinatal em18% e período indefinido em 59% dos pacientes (com FRE pré e perinatal 41% e sem FRE 18%). A tomografia computadorizada (TC) foi realizada em todos os sujeitos e classificada de acordo com dados etiopatogênicos em: TC1= normal (18%); TC2= alargamento ventricular unilateral (25%); TC3= cavidades córtico-subcorticais (28%); TC4= atrofia hemisférica e outros achados (14%); TC5= malformações (15%). A TC5 se associada a malformações físicas fora do sistema nervoso central e aos FRE pré-natais e a TC2 aos perinatais, principalmente, nascer prematuro. A ressonância magnética foi realizada em 57 sujeitos demonstrando boa concordância com a TC. Após associação da neuroimagem e FRE a etiologia ficou indefinida em apenas 37%. Constatou-se alta frequência de FRE perinatais (59%), alertando para melhores cuidados neste período.

The purpose of this paper, which was conducted on 175 children with hemiparetic cerebral palsy (H-CP), was to verify the etiological risk period for this disease. Etiological risk factors (ERF) were detected through anamnesis: 23% in the prenatal period, 18% in the perinatal period and 59% of the patients the period was undefined (ERF in the prenatal and perinatal period was 41% and no ERF was 18% of the cases. The computerized tomographic scan (CT) and MRI were performed on all the patients, who were then classified according to their etiopathogenic data: CT1= normal (18%); CT 2= unilateral ventricular enlargement (25%); CT 3= cortical/ subcortical cavities (28%); CT4= hemispheric atrophy and other findings (14%); CT 5= malformations (15%). CT 5 was associated with physical malformations beyond the central nervous system and with prenatal ERF's , while CT 2 was associated with the perinatal ERF's, mainly in premature births. Magnetic resonance imaging was performed on 57 patients and demonstrated a good degree of concordance with the CT. Etiology remained undefined in only 37% of the cases after neuroimaging was related to ERF. A high perinatal RF frequency (59%) was observed and emphasized the need for special care during this period.
