Indicações e uso da técnica "sonda-dedo"

A recomendação da Organização Mundial da Saúde é que todo recém nascido deva ser alimentado exclusivamente no seio materno até o sexto mês e, de forma complementar, até o segundo ano de vida. Assim, algumas técnicas são realizadas para facilitar a alimentação ao seio, dentre elas o uso do copo e, recentemente, a utilização da técnica "sonda-dedo". Tal prática é bastante controversa e há escassez de estudos na literatura sobre a descrição da técnica, sua indicação e uso. O objetivo do presente trabalho é relatar a experiência clínica para indicação e uso da técnica "sonda-dedo". A técnica "sonda-dedo" consiste no oferecimento do leite, de preferência humano, utilizando sonda gástrica conectada a uma seringa com êmbolo e fixada em dedo mínimo enluvado com fita adesiva. A sonda é posicionada na cavidade oral do recém nascido e deve servir como uma técnica de auxílio para adequação do padrão de sucção. Desta forma, sugere-se que sua indicação deve ser apenas nos casos em que seja caracterizada uma disfunção oral, seja em recém nascidos a termo ou pré-termo. Diante da avaliação específica, realizada pelo fonoaudiólogo, indica-se a técnica "sonda-dedo" com objetivo de adequar as alterações obtidas na avaliação da sucção não nutritiva ou em seio materno. Acredita-se que, para que a técnica "sonda-dedo" seja indicada como complemento do aleitamento materno, devam ser realizados novos estudos para esclarecer quais as repercussões da técnica "sonda-dedo" na prevalência do aleitamento materno e no desenvolvimento motor oral de recém nascidos.

Leg preference and interlateral performance asymmetry in soccer player children

Strength of leg peference and interlateral asymmetry in kinematics of kicking a ball for power were assessed in 6- to 10-year-old right-footed soccer player children. Leg preference was evaluated separately for three task categories: balance stabilization, soccer related mobilization, and general mobilization. The results showed that while both categories of mobilization tasks were featured by a consistent preference for the right leg, in stabilization tasks we observed lower scores and greater interindividual variability of leg preference. No effect of age was detected on leg preference. Analysis of peak foot velocity revealed similar increment of performance of the right and left legs from the ages 6-8 to 10 years. This finding supports the notion of stable Magnitude of interlateral asymmetries of performance during motor development. (C) 2008 Wiley Periodicals, Inc. Dev Psychobiol 50: 799-806, 2008.

Postural control and movement performance during upper limb tasks in children with developmental co-ordination disorder (DCD)

At least 6% of primary school aged children present with DCD, where co-ordination is substantially below the normal range for the child’s age and intelligence. Motor skill difficulties negatively affect academic achievement, recreation and activities of daily living. Poor upper-limb co-ordination is a common difficulty for children with DCD. A possible cause of this problem is deviant muscle timing in proximal muscle groups, which results in poor postural and movement control. While studies have been published investigating postural control in response to external perturbations, detail about postural muscle activity during voluntary movement is limited even in children with normal motor development. No studies have investigated the relationship between muscle timing, resultant arm motion and upper-limb coordination deficits. Objectives: To investigate the relationship between functional difficulties with upper-limb motor skills and neuromuscular components of postural stability and coordination. Specifically, to investigate onset-timing of muscle activity, timing of arm movement, and resultant three-dimensional (3D) arm co-ordination during rapid, voluntary arm movement and to analyse differences arising due to the presence of DCD. This study is part of a larger research program investigating postural stability and control of upper limb movement in children. Design: A controlled, cross-sectional study of differences between children with and without DCD. Methods: This study included 50 children aged eight to 10 years (25 with DCD and 25 without DCD). Children participated in assessment of motor skills according to the Movement ABC Test and a laboratory study of rapid, voluntary arm movements. Parameters investigated included muscle activation timing of shoulder and trunk muscles (surface electromyography), arm movement timing (light sensor) and resultant 3D arm motion (Fastrak). Results: A MANOVA is being used to analyse between-group differences. Preliminary results indicate children with DCD demonstrate altered muscle timing during a rapid arm raise when compared with the control group of children. Conclusion: Differences in proximal muscle timing in children with DCD support the hypothesis that altered proximal muscle activity may contribute to poor proximal stability and consequently poor arm movement control. This has implications for clinical physiotherapy.

Desafios da aprendizagem cooperativa : procurando ultrapassar as disfunções motoras

O presente trabalho incidiu na temática da Educação Inclusiva numa perspectiva de respeito da individualidade de cada um, resposta às necessidades educativas individuais e socialização de aprendizagens, procurando ultrapassar as disfunções motoras da Joana M., individualmente e na turma, através da aprendizagem cooperativa. Teve como alicerce a investigação-acção, preconizando a mudança educativa, dinamizando diagnóstico, planeamento, intervenção e avaliação. Depois de uma investigação teórica necessária à sustentação da temática em questão, procedeu-se à recolha e análise de dados, utilizando a pesquisa documental, a entrevista, a observação naturalista e a sociometria. Da caracterização da turma, da aluna e dos contextos em que as mesmas se inserem, partimos para uma intervenção estruturada, a longo e a curto prazo, numa dinâmica de planificação/acção/reflexão, geradora de práticas educativas diferenciadas e inclusivas. Os resultados obtidos indicam-nos que a aluna está incluída na turma mantendo um nível de interacção positivo com os colegas. Ao longo das sessões de trabalho, a turma demonstrou-se cada vez mais predisposta e receptiva a actividades que envolvessem a sua motricidade global, cooperando e interagindo harmoniosamente. As dificuldades reveladas pela aluna “caso” ajudaram a evidenciar as de alguns dos seus pares, a serem trabalhadas em conjunto, e de algum modo a serem superadas. A parceria com a professora titular de turma revelou-se um bom momento de aprendizagem cooperativa e de socialização de saberes.

Prontidão escolar: validação de um instrumento Lollipop Test numa amostra portuguesa: crenças de progenitores e educadores de infância

Dissertação de mestrado integrado em Psicologia

Estudo de validação da versão portuguesa da Alarm Distress Baby Scale (ADBB)

Contexto. O comportamento de retraimento social prolongado da criança é um importante sinal de alarme, quer tenha origem orgânica, psicológica e/ou social. A. Guédeney construiu a Alarm Distress Baby Scale (ADBB), para identificar este comportamento no contexto da consulta pediátrica ou da observação psicológica. Objectivos. Validação da versão portuguesa da ADBB destinada a avaliar o comportamento de retraimento social de crianças com idades compreendidas entre 2 e 24 meses. Metodologia A ADBB e as Bayley Scales of Infant Development (BSID) foram administradas a uma amostra de 130 lactentes com 3 meses de idade, cujas mães preencheram a versão portuguesa da Edinburgh Postnatal Depression Scale (EPDS); 51 bebés foram novamente avaliados aos 12 meses de idade. Resultados. Os itens da ADBB organizam-se satisfatoriamente em duas sub-escalas. A consistência interna do instrumento é razoável (alpha de Cronbach = .587). A validade externa é elevada: a correlação entre os resultados na ADBB e nas BSID é muito significativa - os bebés que aos 3 meses apresentam um resultado igual ou superior a 5 na ADBB evidenciam menor desenvolvimento nas BSID. Os resultados testemunham ainda que bebés de mães deprimidas (EPDS ≥ 12) mostram mais sinais de retraimento social do que os bebés das mães não deprimidas. Conclusão. A escala permite detectar crianças a necessitar de ajuda no sentido de contrariar o retraimento social que encetaram em relação ao meio. Desenhada para sinalizar tão precocemente quanto possível o retraimento social do lactente, e na medida em que este é um comprovado sinal da perturbação do desenvolvimento, a ADBB pode estimular os clínicos na procura das suas causas e na intervenção junto das mesmas. Estudos em amostras de crianças com mais idade são necessários. No entanto, os resultados obtidos apontam que a Versão portuguesa da ADBB é robusta e válida.

The phenotype of recurrent 10q22q23 deletions and duplications.

The genomic architecture of the 10q22q23 region is characterised by two low-copy repeats (LCRs3 and 4), and deletions in this region appear to be rare. We report the clinical and molecular characterisation of eight novel deletions and six duplications within the 10q22.3q23.3 region. Five deletions and three duplications occur between LCRs3 and 4, whereas three deletions and three duplications have unique breakpoints. Most of the individuals with the LCR3-4 deletion had developmental delay, mainly affecting speech. In addition, macrocephaly, mild facial dysmorphisms, cerebellar anomalies, cardiac defects and congenital breast aplasia were observed. For congenital breast aplasia, the NRG3 gene, known to be involved in early mammary gland development in mice, is a putative candidate gene. For cardiac defects, BMPR1A and GRID1 are putative candidate genes because of their association with cardiac structure and function. Duplications between LCRs3 and 4 are associated with variable phenotypic penetrance. Probands had speech and/or motor delays and dysmorphisms including a broad forehead, deep-set eyes, upslanting palpebral fissures, a smooth philtrum and a thin upper lip. In conclusion, duplications between LCRs3 and 4 on 10q22.3q23.2 may lead to a distinct facial appearance and delays in speech and motor development. However, the phenotypic spectrum is broad, and duplications have also been found in healthy family members of a proband. Reciprocal deletions lead to speech and language delay, mild facial dysmorphisms and, in some individuals, to cerebellar, breast developmental and cardiac defects.

Metaphyseal chondromatosis combined with D-2-hydroxyglutaric aciduria in four patients.

We report four patients who presented with a severe form of metaphyseal chondromatosis in association with D-2-hydroxyglutaric aciduria (D-2-HGA). All patients showed splaying columns of irregular ossification defects with bulbous metaphyses of the long tubular bones, as well as remarkable involvement of the short tubular and flat bones. The vertebral bodies revealed platyspondyly with irregular, stippled endplates. D-2-HGA has been described as a neurometabolic disorder manifesting a broad range of impairment in mental and motor development. Although hydroxyglutaric acid was excreted in high amounts in the urine of all four patients described herein, no significant neurologic abnormalities were evident. This unusual combination of characteristic skeletal and metabolic abnormalities has rarely been reported. Thus, our report will facilitate the recognition of this distinctive entity, and we suggest that a urine organic acid screening be obtained in patients who present with generalized enchondromatosis.

De novo LMNA mutations cause a new form of congenital muscular dystrophy.

OBJECTIVE: To describe a new entity of congenital muscular dystrophies caused by de novo LMNA mutations. METHODS: Fifteen patients presenting with a myopathy of onset in the first year of life were subjected to neurological and genetic evaluation. Histopathological and immunohistochemical analyses were performed for all patients. RESULTS: The 15 patients presented with muscle weakness in the first year of life, and all had de novo heterozygous LMNA mutations. Three of them had severe early-onset disease, no motor development, and the rest experienced development of a "dropped head" syndrome phenotype. Despite variable severity, there was a consistent clinical pattern. Patients typically presented with selective axial weakness and wasting of the cervicoaxial muscles. Limb involvement was predominantly proximal in upper extremities and distal in lower extremities. Talipes feet and a rigid spine with thoracic lordosis developed early. Proximal contractures appeared later, most often in lower limbs, sparing the elbows. Ten children required ventilatory support, three continuously through tracheotomy. Cardiac arrhythmias were observed in four of the oldest patients but were symptomatic only in one. Creatine kinase levels were mild to moderately increased. Muscle biopsies showed dystrophic changes in nine children and nonspecific myopathic changes in the remaining. Markedly atrophic fibers were common, most often type 1, and a few patients showed positive inflammatory markers. INTERPRETATION: The LMNA mutations identified appear to correlate with a relatively severe phenotype. Our results further broaden the spectrum of laminopathies and define a new disease entity that we suggest is best classified as a congenital muscular dystrophy (LMNA-related congenital muscular dystrophy, or L-CMD).

Nurture versus nature: long-term impact of forced right-handedness on structure of pericentral cortex and basal ganglia.

Does a conflict between inborn motor preferences and educational standards during childhood impact the structure of the adult human brain? To examine this issue, we acquired high-resolution T1-weighted magnetic resonance scans of the whole brain in adult "converted" left-handers who had been forced as children to become dextral writers. Analysis of sulcal surfaces revealed that consistent right- and left-handers showed an interhemispheric asymmetry in the surface area of the central sulcus with a greater surface contralateral to the dominant hand. This pattern was reversed in the converted group who showed a larger surface of the central sulcus in their left, nondominant hemisphere, indicating plasticity of the primary sensorimotor cortex caused by forced use of the nondominant hand. Voxel-based morphometry showed a reduction of gray matter volume in the middle part of the left putamen in converted left-handers relative to both consistently handed groups. A similar trend was found in the right putamen. Converted subjects with at least one left-handed first-degree relative showed a correlation between the acquired right-hand advantage for writing and the structural changes in putamen and pericentral cortex. Our results show that a specific environmental challenge during childhood can shape the macroscopic structure of the human basal ganglia. The smaller than normal putaminal volume differs markedly from previously reported enlargement of cortical gray matter associated with skill acquisition. This indicates a differential response of the basal ganglia to early environmental challenges, possibly related to processes of pruning during motor development.

Tallaako lapsi kielensä päälle? : Motorisen kehityksen yhteys kielelliseen kehitykseen

Summary: Investigating the connection between motor development and language development

Devenir et prise en charge des enfants grands prématurés [Neurodevelopmental outcome of very premature infants].

Very preterm infants are at risk of neurodevelopmental impairments, which may affect motor development, intelligence and behavior. Neurodevelopmental follow-up is offered to these children who represent 1% of Swiss births, and may show abnormal motor tone, which sometimes resolves spontaneously or evolves in cerebral palsy. Standardized tests explore intellectual functioning and may allow the diagnosis of specific learning impediments. Finally, behavior is assessed with standardized questionnaires which can reveal hyperactivity with or without attention deficit, impaired social relations, psychiatric troubles or autism, all more frequent amongst preterm children.
