Clinical characteristics of acute dysphagia in pediatric patients following traumatic brain injury

Primary Objective: To document the clinical characteristics of acute dysphagia in a group of pediatric patients after traumatic brain injury (TBI). Research Design: Prospective group study. Methods: Fourteen subjects (7 males, 7 females), aged 4 years 1 month to 15 years, with moderate or severe TBI (Glasgow Coma Scale [GCS] < 12). Subjects were assessed via clinical bedside examination documenting cognitive status, oromotor function, feeding function, dietary recommendations, and an indication of overall feeding severity Results: A pattern of impaired cognition, altered behavior related to feeding, severe tonal and postural deficits, oromotor, respiratory, and laryngeal impairments, and oral sensitivity issues was revealed. Conclusions: Swallowing impairment was affected by multilevel deficits, which both individually and in combination had a negative impact on swallowing competence and safety. In light of deficits identified, which could not be observed on videofluoroscopic investigation alone, this study highlighted the importance of the clinical bedside examination in assessing dysphagia in pediatric patients post-TBI for identifying targets for intervention.

Diffuse optical light in galaxy clusters. I. Abell 3888

We are undertaking a program to measure the characteristics of the intracluster light ( ICL; total flux, profile, color, and substructure) in a sample of 10 galaxy clusters with a range of cluster mass, morphology, and redshift. We present here the methods and results for the first cluster in that sample, A3888. We have identified an ICL component in A3888 in V and r that contains 13% +/- 5% of the total cluster light and extends to 700 h(70)(-1) kpc (similar to 0.3r(200)) from the center of the cluster. The ICL color in our smallest radial bin is V - r 0.3 +/- 0.1, similar to the central cluster elliptical galaxies. The ICL is redder than the galaxies at 400 h(70)(-1) kpc < r < 700 h(70)(-1) kpc, although the uncertainty in any one radial bin is high. Based on a comparison of V - r color with simple stellar models, the ICL contains a component that formed more than 7 Gyr ago ( at z less than 1) with a high-metallicity ( 1.0 Z(circle dot) < Z(ICL) less than or similar to 2.5 Z(circle dot)) and a more centralized component that contains stars formed within the past 5 Gyr ( at z similar to 1). The profile of the ICL can be roughly fitted by a shallow exponential in the outer regions and a steeper exponential in the central region. We also find a concentration of diffuse light around a small group of galaxies 1.4 h(70)(-1) Mpc from the center of the cluster. In addition, we find three low surface brightness features near the cluster center that are blue ( V - r 0.0) and contain a total flux of 0.1M*. Based on these observations and X-ray and galaxy morphology, we suggest that this cluster is entering a phase of significant merging of galaxy groups in the core, whereupon we expect the ICL fraction to grow significantly with the formation of a cD galaxy, as well as the infall of groups.

Near-hanging as presenting to hospitals in Queensland: Recommendations for practice

Near-hanging is an increasing presentation to hospitals in Australasia. We reviewed the clinical management and outcome of these patients as they presented to public hospitals in Queensland. A retrospective clinical record audit was made at five public hospitals between 1991 and 2000. Of 161 patients enrolled, 82% were male, 8% were Indigenous and 10% had made a previous hanging attempt. Chronic medical illnesses were documented in 11% and previous psychiatric disorders in 42%. Of the 38 patients with a Glasgow Coma Scale score (GCS) of 3 on arrival at hospital, 32% returned to independent living and 63% died. Fifty two patients received CPR, of whom 46% had an independent functional outcome. Independent predictors of mortality were a GCS on hospital arrival of 3 (AOR 150, CI 95% 12.4-1818, P

NARRATIVAS DE USOS PEDAGÓGICOS DE FERRAMENTAS TECNOLÓGICAS NA DOCÊNCIA DO ENSINO MÉDIO

O trabalho intitulado Narrativas de usos pedagógicos de ferramentas tecnológicas na docência do Ensino Médio tem como objetivo conhecer e mapear as experiências de professores do Ensino Médio que integram em sua prática pedagógica recursos tecnológicos através de suas narrativas, os quais atuam em escolas públicas da região de São Paulo. Sendo assim, a prática pedagógica com o uso de tecnologia se faz presente na docência do professor de ensino médio, transformando-o em agente mediador do processo ensino-aprendizagem. A metodologia da pesquisa se concentra na experiência dos professores que utilizam a tecnologia como ferramenta de sua prática mediante a investigação narrativa, a qual os autores Connely e Claudinin elucidam em sua obra. São ressaltados alguns autores durante a pesquisa exploratória e documental, como: Moran, Lévy, Perrenoud e Tardif, conceituando a atuação do professor em Freire e Zabala, mediando sua prática com a tecnologia, levando a resultados que propiciam um ensino adequado à aprendizagem. Os instrumentos investigativos da pesquisa adotados na pesquisa foram: entrevista semi-estruturada, conversas informais com os professores, registro dos participantes nos fóruns do Portal educacional e reuniões pedagógicas coma a coordenadora do Portal educacional. O processo organizativo da análise das narrativas dos docentes se realizou por categorias tais como: organização do conteúdo pelos professores, uso do Portal educacional e interdisciplinaridade. Nas narrativas dos participantes da pesquisa percebeu-se que o trabalho na comunidade virtual baseou-se em três pontos fundamentais: produção, troca de informações e apresentação de resultados. De acordo com os relatos apresentados pelos entrevistados conclui-se que o trabalho desenvolvido pelos professores é bastante rico e contribui para a troca de experiências entre docentes pesquisadores da rede, que diferenciam suas aulas através do uso de tecnologia por meio do Portal educacional. Destaca-se também como diferencial na pesquisa a escolha, pelos docentes, de algumas ferramentas com o uso do Portal.

SEMEANDO A CIDADANIA: um estudo sobre a formação e a atuação de educadoras sociais em prol do letramento

Esta dissertação de Mestrado tem como objetivo desvelar a prática pedagógica de educadoras leigas atuantes na educação não-formal e a práxis educacional que elas desempenham em prol da alfabetização letrada. Ao abordarmos os três temas que regem este estudo educação não-formal, formação de educadoras leigas e alfabetização letrada versamos sobre os resultados obtidos em espaços de educação não-formais, estabelecendo um contraponto: até quando o não-formal pode ser considerado um espaço de educação aquém da escola? Foi realizada uma pesquisa empírica no Projeto Sementinha da cidade de Santo André/ SP, através da observação da práxis educativa de sete educadoras, de entrevistas, coma exsecretária de Educação que implantou o Projeto na cidade; com os Coordenadores Gerais do Projeto Sementinha; com quatro das sete educadoras e ainda, um levantamento bibliográfico sobre o surgimento do Projeto na cidade de Curvelo; MG. Até o momento, as análises realizadas apontaram para o desenvolvimento de práticas de letramento em diferentes momentos da atuação das educadoras e na formação cidadã e moral das crianças assistidas pelo Projeto na comunidade observada para a efetivação deste trabalho de pesquisa.(AU)

Bem-estar subjetivo de genitores e prevalência de diagnósticos psiquiátricos de crianças

Bem-estar subjetivo (BES) envolve um conjunto de categorias com componentes cognitivos e emocionais utilizados pelas pessoas para avaliar sua própria vida. Não se trata de uma avaliação objetiva feita por observadores com relação à qualidade de vida de uma pessoa, mas da avaliação subjetiva de cada indivíduo sobre a qualidade de sua própria vida, sobre a satisfação experimentada no quotidiano. Assim, BES representa uma avaliação pessoal sobre quão feliz o indivíduo se sente, independentemente do contexto e das condições socioeconômicas, da saúde, do sucesso e de outras variáveis que poderiam permitir uma avaliação objetiva de qualidade de vida. Supõe-se que pais de crianças com problemas avaliem-se como menos felizes do que outros e que o diagnóstico de problemas esteja associado a um menor relato de BES. Assim, o objetivo deste estudo foi verificar relações entre bem-estar subjetivo de genitores e diagnósticos psiquiátricos de crianças. Para a realização deste estudo foram aplicados questionários para 70 genitores com filhos em atendimento psicológico na Unidade de Saúde da Criança e Adolescente. Resultados de análises de variância, testes t e de qui-quadrados revelaram não haver relações entre bem-estar subjetivo dos pais e presença de transtorno em seus filhos. Sequer houve diferenças entre BES de pais e mães ou entre BES de genitores de meninos e meninas. Além disso, esses genitores possuíam níveis razoáveis de BES, composto por bons índices de satisfação geral com a vida e balanço emocional baixo, o que revela uma quase neutralidade afetiva. Discussões apontam para a necessidade de estudos que complementem esses achados.

Operator-induced errors in Hartmann-Shack wavefront sensing:model eye study

Purpose: To evaluate the effects of instrument realignment and angular misalignment during the clinical determination of wavefront aberrations by simulation in model eyes. Setting: Aston Academy of Life Sciences, Aston University, Birmingham, United Kingdom. Methods: Six model eyes were examined with wavefront-aberration-supported cornea ablation (WASCA) (Carl Zeiss Meditec) in 4 sessions of 10 measurements each: sessions 1 and 2, consecutive repeated measures without realignment; session 3, realignment of the instrument between readings; session 4, measurements without realignment but with the model eye shifted 6 degrees angularly. Intersession repeatability and the effects of realignment and misalignment were obtained by comparing the measurements in the various sessions for coma, spherical aberration, and higher-order aberrations (HOAs). Results: The mean differences between the 2 sessions without realignment of the instrument were 0.020 μm ± 0.076 (SD) for Z3 - 1(P = .551), 0.009 ± 0.139 μm for Z3 1(P = .877), 0.004 ± 0.037 μm for Z4 0 (P = .820), and 0.005 ± 0.01 μm for HO root mean square (RMS) (P = .301). Differences between the nonrealigned and realigned instruments were -0.017 ± 0.026 μm for Z3 - 1(P = .159), 0.009 ± 0.028 μm for Z3 1 (P = .475), 0.007 ± 0.014 μm for Z4 0(P = .296), and 0.002 ± 0.007 μm for HO RMS (P = 0.529; differences between centered and misaligned instruments were -0.355 ± 0.149 μm for Z3 - 1 (P = .002), 0.007 ± 0.034 μm for Z3 1(P = .620), -0.005 ± 0.081 μm for Z4 0(P = .885), and 0.012 ± 0.020 μm for HO RMS (P = .195). Realignment increased the standard deviation by a factor of 3 compared with the first session without realignment. Conclusions: Repeatability of the WASCA was excellent in all situations tested. Realignment substantially increased the variance of the measurements. Angular misalignment can result in significant errors, particularly in the determination of coma. These findings are important when assessing highly aberrated eyes during follow-up or before surgery. © 2007 ASCRS and ESCRS.

Mechanism of action of the tetraflex accommodative intraocular lens

PURPOSE:To investigate the mechanism of action of the Tetraflex (Lenstec Kellen KH-3500) accommodative intraocular lens (IOL). METHODS:Thirteen eyes of eight patients implanted with the Tetraflex accommodating IOL for at least 2 years underwent assessment of their objective amplitude-of-accommodation by autorefraction, anterior chamber depth and pupil size with optical coherence tomography, and IOL flexure with aberrometry, each viewing a target at 0.0 to 4.00 diopters of accommodative demand. RESULTS:Pupil size decreased by 0.62+/-0.41 mm on increasing accommodative demand, but the Tetraflex IOL was relatively fixed in position within the eye. The ocular aberrations of the eye changed with increased accommodative demand, but not in a consistent manner among individuals. Those aberrations that appeared to be most affected were defocus, vertical primary and secondary astigmatism, vertical coma, horizontal and vertical primary and secondary trefoil, and spherical aberration. CONCLUSIONS:Some of the reported near vision benefits of the Tetraflex accommodating IOL appear to be due to changes in the optical aberrations because of the flexure of the IOL on accommodative effort rather than forward movement within the capsular bag.

Modelling ocular monochromatic aberrations using schematic eyes with homogeneous optical media

Previous research has indicated that schematic eyes incorporating aspheric surfaces but lacking gradient index are unable to model ocular spherical aberration and peripheral astigmatism simultaneously. This limits their use as wide-angle schematic eyes. This thesis challenges this assumption by investigating the flexibility of schematic eyes comprising aspheric optical surfaces and homogeneous optical media. The full variation of ocular component dimensions found in human eyes was established from the literature. Schematic eye parameter variants were limited to these dimensions. The levels of spherical aberration and peripheral astigmatism modelled by these schematic eyes were compared to the range of measured levels. These were also established from the literature. To simplify comparison of modelled and measured data, single value parameters were introduced; the spherical aberration function (SAF), and peripheral astigmatism function (PAF). Some ocular components variations produced a wide range of aberrations without exceeding the limits of human ocular components. The effect of ocular component variations on coma was also investigated, but no comparison could be made as no empirical data exists. It was demonstrated that by combined manipulation of a number of parameters in the schematic eyes it was possible to model all levels of ocular spherical aberration and peripheral astigmatism. However, the unique parameters of a human eye could not be obtained in this way, as a number of models could be used to produce the same spherical aberration and peripheral astigmatism, while giving very different coma levels. It was concluded that these schematic eyes are flexible enough to model the monochromatic aberrations tested, the absence of gradient index being compensated for by altering the asphericity of one or more surfaces.

A preliminary investigation into the effects of ocular lubricants on higher order aberrations in normal and dry eye subjects

Purpose: To study the effects of ocular lubricants on higher order aberrations in normal and self-diagnosed dry eyes. Methods: Unpreserved hypromellose drops, Tears Again™ liposome spray and a combination of both were administered to the right eye of 24 normal and 24 dry eye subjects following classification according to a 5 point questionnaire. Total ocular higher order aberrations, coma, spherical aberration and Strehl ratios for higher order aberrations were measured using the Nidek OPD-Scan III (Nidek Technologies, Gamagori, Japan) at baseline, immediately after application and after 60. min. The aberration data were analyzed over a 5. mm natural pupil using Zernike polynomials. Each intervention was assessed on a separate day and comfort levels were recorded before and after application. Corneal staining was assessed and product preference recorded after the final measurement for each intervention. Results: Hypromellose drops caused an increase in total higher order aberrations (p= <0.01 in normal and dry eyes) and a reduction in Strehl ratio (normal eyes: p= <0.01, dry eyes p= 0.01) immediately after instillation. There were no significant differences between normal and self-diagnosed dry eyes for response to intervention and no improvement in visual quality or reduction in higher order aberrations after 60. min. Differences in comfort levels failed to reach statistical significance. Conclusion: Combining treatments does not offer any benefit over individual treatments in self-diagnosed dry eyes and no individual intervention reached statistical significance. Symptomatic subjects with dry eye and no corneal staining reported an improvement in comfort after using lubricants. © 2013 British Contact Lens Association.
