RESUMO

OBJECTIVES: To study the effects of age and cognition on the performance of children aged 3 to 18 years on a culturally adapted version of the 16 item smell identification test from Sniffin' Sticks (SS16). METHODS: A series of pilots were conducted on 29 children aged 3 to 18 years old and 23 adults to produce an adapted version of the SS16 suitable for Brazilian children (SS16-Child). A final version was applied to 51 children alongside a picture identification test (PIT-SS16-Child) to access cognitive abilities involved in the smell identification task. In addition 20 adults performed the same tasks as a comparison group. RESULTS: The final adapted SS16-Child was applied to 51 children with a mean age of 9.9 years (range 3-18 years, SD=4.25 years), of which 68.3% were girls. There was an independent effect of age (p<0.05) and PIT-SS16-Child (p<0.001) on the performance on the SS16-Child, and older children reached the ceiling for scoring in the cognitive and olfactory test. Pre-school children had difficulties identifying items of the test. DISCUSSION/CONCLUSIONS: A cross-culturally adapted version of the SS16 can be used to test olfaction in children but interpretation of the results must take age and cognitive abilities into consideration.

RESUMO

OBJECTIVE: To assess the neurodevelopmental functions (cognition, language and motor function) of survivors of twin-twin transfusion syndrome (TTTS). METHOD: Observational cross-sectional study of a total of 67 monochorionic diamniotic twins who underwent fetoscopic laser coagulation (FLC) for treatment of TTTS. The study was conducted at the Center for Investigation in Pediatrics (CIPED), Universidade Estadual de Campinas. Ages ranged from one month and four days to two years four months. Bayley Scales of Infant and Toddler Development Screening Test-III, were used for evaluation. RESULTS: Most children reached the competent category and were classified as having appropriate performance. The preterm children scored worse than term infants for gross motor subtest (p = 0.036). CONCLUSION: The majority of children reached the expected development according to their age. Despite the good neurodevelopment, children classified at risk should be monitored for development throughout childhood.

RESUMO

OBJECTIVE: Compare the self-esteem of adolescents with epilepsy and adolescents without epilepsy and relate it to social support and seizure controllability perception. METHOD: The study sample consisted: case participants (34 subjects) attending the pediatric epilepsy clinic of University Hospital and control participants (30 subjects) from public schools in Campinas-SP. The instruments utilized were: identification card with demographic and epilepsy data, a semi-structured interview on aspects of the disease, and a Self-Esteem Multidimensional Scale. RESULTS: There was no significant difference between the two groups but majority of adolescents with epilepsy presented higher self esteem rate, have knowledge about epilepsy, presented high levels of social support and seizure controllability perception. There was no significant relationship between social support and seizure controllability perception with self-esteem. CONCLUSION: Knowledge about epilepsy, social support such good controllability seizure perception seem are important contingencies for a better evaluation of self esteem in adolescents with epilepsy.

OBJETIVO: Comparar a autoestima de adolescentes com epilepsia e adolescentes sem epilepsia e relacioná-la com percepção de suporte social e controlabilidade de crises. MÉTODO: A amostra do estudo consiste: grupo caso (34 sujeitos) atendidos no ambulatório de epilepsia infantil do Hospital Universitário e grupo controle (30 indivíduos) de escolas públicas de Campinas-SP. Os instrumentos utilizados foram: cartão de identificação com dados demográficos e de epilepsia, entrevista semiestruturada sobre os aspectos da doença e Escala Multidimensional de autoestima. RESULTADOS: Não houve diferença significativa entre os dois grupos, mas a maioria dos adolescentes com epilepsia apresentou maior pontuação de autoestima, conhecimento sobre epilepsia, altos níveis de suporte social e percepção de controlabilidade das crises. Não houve relação significativa entre suporte social e percepção de controlabilidade das crises com a autoestima. CONCLUSÃO: Conhecimento sobre a epilepsia, percepção de apoio social assim como boa controlabilidade de crises parecem ser contingências importantes para uma melhor avaliação da autoestima em adolescentes com epilepsia.

RESUMO

Malformations of cortical development have been described in children and families with language-learning impairment. The objective of this study was to assess the auditory processing information in children with language-learning impairment in the presence or absence of a malformation of cortical development in the auditory processing areas. We selected 32 children (19 males), aged eight to 15 years, divided into three groups: Group I comprised 11 children with language-learning impairment and bilateral perisylvian polymicrogyria, Group II comprised 10 children with language-learning impairment and normal MRI, and Group III comprised 11 normal children. Behavioral auditory tests, such as the Random Gap Detection Test and Digits Dichotic Test were performed. Statistical analysis was performed using the Kruskal-Wallis test and Mann-Whitney test, with a level of significance of 0.05. The results revealed a statistically significant difference among the groups. Our data showed abnormalities in auditory processing of children in Groups I and II when compared with the control group, with children in Group I being more affected than children in Group II. Our data showed that the presence of a cortical malformation correlates with a worse performance in some tasks of auditory processing function.

RESUMO

TEMA: processamento temporal auditivo e dislexia do desenvolvimento. OBJETIVO: caracterizar o processamento temporal auditivo em escolares com dislexia do desenvolvimento e correlacionar com malformação cortical. MÉTODO: foram avaliados 20 escolares, com idade entre 8 e 14 anos, divididos em grupo experimental (GE) composto por 11 escolares (oito do gênero masculino) com o diagnóstico de dislexia do desenvolvimento e grupo controle (GC) composto por nove escolares (seis do gênero masculino) sem alterações neuropsicolinguísticas. Após avaliações neurológica, neuropsicológica e fonoaudiológica (avaliação de linguagem e leitura e escrita) para obtenção do diagnóstico, os escolares foram submetidos à avaliação audiológica periférica e posteriormente aplicou-se o teste Random Gap Detection Test e/ou Random Gap Detection Test Expanded. RESULTADOS: observou-se diferença estatisticamente significante entre os escolares do GE e GC, com pior desempenho para o GE. A maioria dos escolares do GE apresentou polimicrogiria perisylviana. CONCLUSÃO: escolares com dislexia do desenvolvimento podem apresentar alterações no processamento temporal auditivo com prejuízo no processamento fonológico. Malformação do desenvolvimento cortical pode ser o substrato anatômico dos distúrbios.


BACKGROUND: temporal auditory processing and developmental dyslexia. AIM: to characterize the temporal auditory processing in children with developmental dyslexia and to correlate findings with cortical malformations. METHOD: twenty school-aged children, ranging in age from 8 to 14 years were evaluated. These children were divided into two groups: the experimental group (EG) was composed by 11 children (eight were male) with developmental dyslexia and the control group (CG) was composed by nine normal children (six were male). After neurological assessment and verification of the intellectual level, language, reading and writing skills in order to determine the diagnosis, children underwent a peripheral audiological evaluation and Random Gap Detection Test and/or Random Gap Detection Test Expanded. RESULTS: a statistically significant difference between children in the EG and CG were observed, with children in the EG presenting worst performances. Most of the children in the EG presented perisylvian polymicrogyria. CONCLUSION: children with developmental dyslexia may present temporal auditory processing disorders with deficits in phonological processing. Cortical malformations may be the anatomical substrate of these disorders.

RESUMO

BACKGROUND: Rolandic Epilepsy is the most common form of childhood epilepsy. It is classified as idiopathic, age-related epileptic syndrome with benign evolution. The absence of neuropsychological impairment is part of the criteria of benignity of this epilepsy syndrome. Recently, however, several deficits related to attention and language have been suggested. AIM: to assess school performance and to investigate praxis problems in patients with rolandic epilepsy in comparison to a control group of normal children, paired by age, gender and educational level. METHOD: nineteen patients aged between 7 and 12 years underwent clinical neurological evaluation, psychological assessment, through the Weschsler Scales of Intelligence, and language evaluation, to assess the academic performance and to investigate the presence or absence of praxis difficulties. RESULT: the obtained data indicate that although intellectual efficiency (measured through the Intelligence Quatient - IQ) was within average, children with rolandic epilepsy presented a significantly poorer performance when compared to the control group in tests involving writing, arithmetic and reading. Another important aspect was the absence of orofacial apraxia in children with epilepsy. CONCLUSION: the results of the study suggest that the assessment of children with epilepsy is necessary to investigate specific deficits that require appropriate professional assistance. Regarding the presence of oral language and/or writing disorders in these children, academic, social and emotional deficits can be avoided. The prognosis of epileptic syndrome does not exclusively depend on the control of the crises, since social or cultural problems can interfere in life quality as much as the crisis.

RESUMO

TEMA: Epilepsia Rolândica é a forma mais freqüente de epilepsia da infância. Ela é classificada como idiopática, idade-dependente e de evolução benigna. A ausência de comprometimento neuropsicológico faz parte dos critérios de benignidade desta síndrome epiléptica.Entretanto, recentemente têm sido sugeridos vários déficits relacionados à atenção e linguagem. OBJETIVO: o objetivo desse trabalho foi avaliar o desempenho escolar e investigar dificuldades práxicas em pacientes com epilepsia rolândica e comparar a um grupo controle composto por crianças normais com idade, gênero e nível escolar equivalentes. MÉTODO: dezenove pacientes com idade entre 7 e 12 anos foram submetidos a avaliação neurológica clínica, avaliação psicológica, através das Escalas Weschsler de Inteligência e avaliação fonoaudiológica, onde foram avaliados o desempenho escolar e a investigação da presença ou não de dificuldades práxicas. RESULTADOS: os dados mostraram que apesar da eficiência intelectual (medida pelo Quociente Inteligência - QI) estar dentro da média, crianças com epilepsia rolândica mostraram um desempenho significativamente mais pobre do que o grupo controle em provas de escrita, aritmética e leitura. Outro aspecto importante evidenciado foi a ausência de apraxia orofacial nas crianças do grupo afetado. CONCLUSÃO: deve ser ressaltado que a avaliação de crianças com epilepsia é necessária porque isso pode revelar distúrbios específicos que exigem ajuda profissional apropriada. Analisando a ocorrência de distúrbios de linguagem oral e/ou escrita nessas crianças, pode-se evitar um maior prejuízo acadêmico, social e emocional, afinal o prognóstico de uma síndrome epiléptica não depende exclusivamente do controle de crises, pois problemas sociais ou culturais podem interferir tanto quanto as crises na qualidade de vida dos pacientes.

RESUMO

We hypothesized that the processing of auditory information by the perisylvian polymicrogyric cortex may be different from the normal cortex. To characterize the auditory processing in bilateral perisylvian syndrome, we examined ten patients with perisylvian polymicrogyria (Group I) and seven control children (Group II). Group I was composed by four children with bilateral perisylvian polymicrogyria and six children with bilateral posterior perisylvian polymicrogyria. The evaluation included neurological and neuroimaging investigation, intellectual quotient and audiological assessment (audiometry and behavior auditory tests). The results revealed a statistically significant difference between the groups in the behavioral auditory tests, such as, digits dichotic test, nonverbal dichotic test (specifically in right attention), and random gap detection/random gap detection expanded tests. Our data showed abnormalities in the auditory processing of children with perisylvian polymicrogyria, suggesting that perisylvian polymicrogyric cortex is functionally abnormal. We also found a correlation between the severity of our auditory findings and the extent of the cortical abnormality.

RESUMO

OBJETIVOS: As malformações do córtex cerebral (MCC) são uma causa importante de epilepsia. Nossas metas foram: triagem de mutações em genes associados às MCC (FLN1, LIS1, DCX e EMX2), investigar funcionalmente as mutações e mapear o locus para polimicrogiria perisylviana familiar. MÉTODOS: A triagem de mutações foi realizada por PCR, DHPLC e sequênciamento. Estudo funcional foi realizado por RT-PCR, PCR em tempo real e HUMARA. O estudo de ligação foi realizado por PCR e análise com programas Fragment Profiler® e MLINK®. RESULTADOS: Mutações deletérias foram identificadas em 3/108 pacientes. Uma mutação de splicing (G987C) em FLN1 foi identificada em duas pacientes aparentadas com heterotopia nodular periventricular. Mudança no padrão de inativação do cromossomo X é responsável pelas diferenças clínicas entre as pacientes. Uma substituição A1385C (H277P) foi identificada em LIS1 em um indivíduo com lissencefalia. Alterações neutras foram identificadas em DCX e EMX2. A análise de ligação identificou um locus em Xq27.2-Xq27.3 para polimicrogiria familiar. CONCLUSÃO: Mosaicismo, mutações em regiões não codificantes, deleções, rearranjos e casos atípicos podem estar contribuindo para a baixa freqüência de mutações identificadas. Esquizencefalia e polimicrogiria parecem não ter base genética relacionada com o gene EMX2. Um novo locus candidato em Xq27.2-Xq27.3 foi identificado para polimicrogiria perisylviana familiar.


OBJECTIVES: Malformations of cerebral cortex (MCC) are an important cause of epilepsy. Our main goals were: to search for mutations in genes responsible for MCC (FLN1, LIS1, DCX and EMX2), to map the locus for familial perisylvian polymicrogyria and to investigate the molecular mechanisms of the mutations identified. Methods: Mutation screening was performed by PCR, DHPLC and sequencing. HUMARA and Real Time PCR were performed to study the molecular mechanisms of mutations. Linkage analysis was carried out by PCR, Fragment profiler® and MLINK® software. RESULTS: Deleterious mutations were identified in 3/108 patients. We found a G987C splicing mutation in the FLN1 in two related patients with periventricular nodular heterotopia. Skewed X-chromosome inactivation was detected as the possible mechanism responsible for clinical differences observed in the two patients. An A1385C transversion (H277P) in LIS1 was identified in one patient with lisencephaly. Only neutral variants were identified in DCX and EMX2. Linkage analysis has detected a locus in Xq27.2-Xq27.3 for familial polymicrogyria. CONCLUSION: We believe that the low frequency of mutations identified may be due to mosaicism, mutations in non-coding regions, deletions and patients with atypical neuroimaging findings. Deleterious mutations in EMX2 were not found in patients with schizencephaly and polymicrogyria. We found a locus for familial perisylvian polymicrogyria in Xq27.2-Xq27.3.

RESUMO

Polymicrogyria (PMG) is a malformation of cortical development characterized by an excessive number of small gyri and abnormal cortical lamination, giving the cortical surface an irregular and gross appearance. The severity of clinical manifestations correlates with the extent of cortical involvement. The objective of the present study was to describe three families with linguistic features of developmental language disorder and reading impairment, and to establish a neuroanatomic correlation through neuroimaging. Subjects have been submitted to a comprehensive protocol including psychological assessment, language evaluation, neurological examination, and neuroimaging investigation. In our families, children usually had the diagnosis of developmental language disorder while adults had the diagnosis of reading impairment. MRI showed perisylvian polymicrogyria in several subjects of each family. Our data support the idea that there is a co-occurrence of developmental language disorder and reading impairment and both conditions may be associated with polymicrogyria.

RESUMO

We describe three unrelated individuals, two males (ages 35 and 9) and a female (age 8) presenting with late diagnosed phenylketonuria (PKU) and autistic behavior, all showing poor adhesion to the dietary treatment resulting in high plasmatic phenylalanine levels, particularly in the oldest subject. Clinical findings included hair hypopigmentation, microcephaly, severe mental retardation with absent development of verbal language and autistic symptoms in all three patients, whereas variable neurological signs such as seizures, spasticity, ataxia, aggressivity, and hyperactivity were individually found. Homozygosity for the IVS10nt11g/a (IVS10nt546) was found in all. This is the first report of molecular findings in subjects with PKU also presenting with autistic features. The authors discuss if this mutation is particularly involved in the association of autistic symptoms in untreated PKU individuals.

Descrevemos três indivíduos não aparentados, dois do sexo masculino (com idades de 35 e nove anos) e um do sexo feminino (com idade de oito anos) apresentando fenilcetonúria diagnosticada tardiamente e comportamento autístico, todos com adesão limitada ao tratamento dietético resultando em altos níveis plasmáticos de fenilalanina, especialmente no indivíduo mais velho. Os achados clínicos incluem hipopigmentação de cabelos, retardo mental grave com ausência de desenvolvimento da linguagem verbal e sintomas autísticos nos três pacientes, enquanto outros achados neurológicos como convulsões, espasticidade, ataxia, agressividade e hiperatividade são descritos em um indivíduo, cada. Homozigose para a mutação IVS10nt11g/a (IVS10nt546) foi encontrada em todos. Este é o primeiro relato de achados moleculares em indivíduos com fenilcetonúria que desenvolveram características autísticas. Discute-se se essa mutação estaria particularmente envolvida no desenvolvimento de sintomas autísticos em indivíduos com fenilcetonúria não tratada.

RESUMO

OBJECTIVE: Although the atypical antipsychotic medications appear to be safe in patients with epilepsy, few studies have specifically addressed the use of risperidone in children with seizures. The objective of this study was to evaluate behavior improvement and seizure outcome in children with epilepsy and behavioral disorders (self-injurious, aggressive, or destructive behavior) after introduction of risperidone. METHODS: In this prospective study, 54 patients were evaluated, 38 boys and 16 girls, aged 2-18 (mean=10). The dose of risperidone ranged from 0.01 to 0.14 mg/kg/day (mean=0.038 mg/kg/day). Risperidone was introduced gradually. The titration rate was determined by clinical response. The data were collected from patients' follow-up visits and clinical files. Exacerbation of seizures was established as an increase in seizure frequency after introduction of risperidone, with return to baseline seizure frequency after risperidone withdrawal. RESULTS: Seizure frequency was not affected by risperidone in 51 patients (94.5%). Only two (4%) patients experienced seizure exacerbation after the introduction of risperidone. In one patient, the effect of risperidone on seizure control could not be established. After introduction of the risperidone, 38 (70.4%) patients manifested improvement in behavior. CONCLUSION: Our data suggest that risperidone can be used in pediatric patients with epilepsy and that seizure outcome is not changed in most children with epilepsy and psychiatric comorbidity. In addition, behavior improvement is usually achieved in most patients.

RESUMO

Specific language impairment (SLI) occurs when children present language maturation, at least 12 months behind their chronological age in the absence of sensory or intellectual deficits, pervasive developmental disorders, evident cerebral damage, and adequate social and emotional conditions. The aim of this study was to classify a group of children according to the subtypes of SLI and to correlate clinical manifestations with cortical abnormalities. Seventeen children with SLI were evaluated. Language assessment was based on standardized test (Peabody) and a non-standardized protocol, which included phonological, syntactical, semantical, pragmatical and lexical aspects of language. All children, except one, had abnormal MRI. Thirteen children presented perisylvian polymicrogyria. The MRI findings in the remaining three patients were: right frontal polymicrogyria, bilateral fronto-parietal atrophy, and hypogenesis of corpus callosum with Chiari I. The data show that patients with posterior cortical involvement tended to present milder form of SLI (no sign of articulatory or bucofacial praxis disturbance), while diffuse polymicrogyric perisylvian cortex usually was seen in patients who presented severe clinical manifestation, mainly phonological-syntactic deficit. In conclusion, SLI may be associated with perisylvian polymicrogyria and clinical manifestation may vary according to the extent of cortical anomaly.
