    Full Text Available Este artigo tem como objetivo analisar as relações de afetividade entre professor e aluno no processo ensino-aprendizagem. Utiliza de metodologia com abordagem qualitativa, observação participante, e entrevistas semi-estruturadas. O lócus da pesquisa foi a Escola Municipal de Educação Básica Lizamara Aparecida Oliva de Almeida em Sinop, entre Fevereiro e Maio de 2014. Enquanto sujeitos, contou-se com professores e alunos do 3º ano do Ensino Fundamental. Dos resultados parciais, verificou-se que mesmo que a afetividade e a aprendizagem sejam reconhecidas teoricamente por Henri Wallon como elos fundamentais para o processo ensino-aprendizagem, ainda não é bem compreendido pelos sujeitos professores. Palavras-chave: psicologia educacional; afetividade; professores e alunos.

    Professor Sergei Semjonovic Golovin (1866-1931) is considered as one of the founders of ophthalmology in Russia. He received a worldwide reputation thanks to his achievements in ocular surgery and pathology. He introduced new surgical techniques such as Golovin's operation (Exenteratio orbitosinualis), Golovin's osteoplastic frontal sinus operation, ligation of orbital veins, and opticociliary neurectomy. He also introduced his "cytotoxic theory" to interpret sympathetic ophthalmia. He was a reputable professor of ophthalmology.

    Full Text Available Este estudo investigou distintas modalidades de barreiras à expressão da criatividade pessoal em uma amostra de 544 professores, que atuavam desde o ensino fundamental até o ensino superior. O Inventário de Barreiras à Criatividade Pessoal, construído e validado pela primeira autora, foi utilizado para coleta de dados. Este instrumento inclui itens relativos a quatro modalidades de barreiras: Inibição/Timidez, Falta de Tempo/Oportunidade, Repressão Social e Falta de Motivação. Diferenças significativas foram observadas entre professores do sexo masculino e feminino em Repressão Social, e, entre professores de diferentes níveis de ensino, nas barreiras denominadas Inibição/Timidez e Repressão Social. Os resultados apontam distintas barreiras que se referem direta ou indiretamente aos motivos, meios e oportunidades para a expressão da criatividade pessoal, sinalizando a necessidade de estratégias que ampliem as possibilidades de expressão criativa em professores.

  6. Tabus sexuais entre professores e alunos Sexual taboos among teachers and students

    2008-08-01

    Full Text Available O poder da sexualidade nas relações entre professores e alunos é tão intenso quanto o esforço feito pelos agentes educacionais em negá-lo. O termo tabu representa a exata designação do que tal terminologia suscita: algo misterioso e, principalmente, proibido. De fato, a questão sexual entre professores e alunos concerne a uma esfera tão proibitiva que sequer é mencionada, haja vista a escassez de pesquisas que versam a esse respeito. Daí o objetivo deste artigo, ou seja, analisar a ambivalência dos sentimentos de amor e de ódio que se objetivam na sexualidade existente entre professores e alunos.The power of sexuality in teacher-student relationships is as intense as the effort made by educational institutions to deny it. The term "taboo"represents the exact designation of what such terminology means: something mysterious and mainly forbidden. In fact, the sexual issue among teachers and students concerns such a forbidding sphere that it is hardly mentioned, which explains the little research that has been carried out in this field. Thus, this paper is aimed at analyzing the ambivalence of feelings of love and hate found in the teacher-student sexuality.

    Full Text Available Objetivo: Identificar percepções de professores do sistema público de ensino, em relação aos erros de refração manifestados na idade escolar, a fim de subsidiar programas de treinamento para docentes, visando à detecção e posterior assistência a problemas oftálmicos de escolares. Métodos: Estudo transversal em população de professores de primeira série do ensino fundamental, de todas as escolas públicas da região sul do município de São Paulo. Aplicou-se questionário estruturado com base em estudo exploratório. Resultados: Foi obtida uma população de 545 sujeitos, distribuídos em 120 escolas. A população apresentou média de idade de 37,8 anos e média de tempo de magistério de 13,2 anos. A maioria (67,4% não recebeu orientação sobre saúde ocular nos últimos três anos. Os professores distinguiram mais corretamente os sinais de miopia (70,8% do que os de hipermetropia (42,9% e astigmatismo (40,9%. Proporção significativa (48,5% apontou sinais e comportamentos indicativos da presença de miopia no escolar; 40,9% apontaram dificuldades na leitura e na escrita, para a criança hipermétrope sem correção óptica. Na criança astigmata as manifestações mais mencionadas foram "vista embaçada" (45,4% e desinteresse por atividades que exigem esforço visual (40,9%. Os professores classificaram todos os erros de refração como agravos muito graves. Conclusão: Foram evidenciados conhecimentos distorcidos e/ou insuficientes entre professores do ensino fundamental, a respeito de erros de refração manifestados na idade escolar.

    Full Text Available O presente estudo teve por objetivo principal: mapear e analisar o nível e a forma de articulação entre os professores e as atividades desenvolvidas em Salas de Recursos Multifuncionais (SRMs e salas comuns, em uma proposta inclusiva. Com o intuito de contribuir para o processo da educação inclusiva no ambiente escolar, estabeleceu-se aqui a abordagem quanti-qualitativa do tipo transversal. Utilizou-se um questionário para os professores de sala comum e professores de SRM. Participaram deste estudo dezesseis professores de sala comum que tinham alunos com deficiência e nove de SRM da rede pública de ensino de dois municípios da Região Metropolitana de Campinas. Para a análise de conteúdo dos questionários, tomou-se como referência a obra de Bardin, que aponta três fases fundamentais no processo: pré-análise, exploração do material e tratamento dos resultados. Por meio deste estudo, foi possível concluir que: (a os professores estão cientes da importância da SRM e das atribuições dos professores que atuam nesse espaço - todavia, não parece estar claro o trabalho do professor da sala comum -, (b há uma inter-relação entre professores de sala comum e SEM - todavia falta maior tempo destinado às trocas necessárias -, e (c em alguns casos, há falta de entendimento do professor de sala comum sobre a sua função quanto ao aluno Público-Alvo da Educação Especial (PAEE.

    Full Text Available RESUMO: Apresentamos um estudo a partir de duas investigações sobre o LASEB-FaE-UFMG, curso de especialização que contemplava uma turma de Educação Matemática, no qual analisamos as relações construídas entre professores que ensinam Matemática e professores licenciados em Matemática. As pesquisas, concluídas em 2013, abordam a convivência, por dezoito meses, dos docentes atuantes no primeiro e no segundo segmentos do Ensino Fundamental, explicitando diferenciações e identidades. Entre encontros e desencontros, os docentes mostraram ter aprendido uns com os outros, ampliando sua formação nos conteúdos e no seu ensino, o que foi possibilitado pela abordagem eleita para o curso, pautada no campo da Educação Matemática. Percebemos ter se evidenciado, nos contatos, a afirmação das identidades dos docentes "generalistas" e "especialistas". A experiência se mostrou rica na construção de interações e aprendizagens sobre cada um, bem como sobre os processos formativos do Ensino Fundamental, remetendo-se a reflexões sobre a formação inicial docente.

Partindo de uma reflexão sobre o Ensino de História e analisando o caráter narrativo da história, passando por autores como Hayden White, Peter Gay, Jörn Rüsen, Paul Ricoeur, e Walter Benjamin, desejamos compreender quais estratégias são utilizadas pelos professores na construção de suas aulas. Interessa-nos compreender quais elementos narrativos e de estilo compõem um discurso histórico capaz de obter a adesão do auditório escolar, a partir de referenciais da Nova Retórica. Nessa análise, o que propomos é uma arte, relacionando a narrativa com a criação subjetiva e a experiência vivida (no caso, a experiência histórica, compreendendo como os professores de História elaboram o conhecimento historiográfico em suas aulas. Essa elaboração visa a negociar a distância entre o tempo passado e o momento do aluno, gerando momentos de encantamento ao poder da palavra.

    Full Text Available RESUMO Introdução: A inatividade física onera a sociedade pelo crescente custo dos cuidados médicos e perda de produtividade, além de figurar entre os quatro principais fatores de risco de doenças crônicas. Objetivo: Verificar os fatores associados à inatividade física, avaliada pela taxa de equivalentes metabólicos (MET, entre professores de uma universidade pública. Métodos: Estudo transversal, com amostra probabilística, incluindo 163 trabalhadores. Além da inatividade física (<450 MET.min/semana, avaliaram-se idade, sexo, estado civil, tabagismo, consumo excessivo de álcool, percepção da saúde e do estresse, presença de diabetes, hipertensão, lombalgia, depressão, doenças do coração e consumo de frutas/verduras/legumes, gordura não saudável, refrigerante e sal. As razões de prevalências e os intervalos de confiança (95% foram estimados pela regressão de Poisson. Resultados: Os participantes fisicamente inativos tinham menor consumo de frutas/verduras/legumes, consumo excessivo de álcool e pior percepção da saúde. Conclusão: Sugere-se que a inatividade física está associada a um maior perfil de risco de saúde, e a ocorrência simultânea desses fatores deve ser considerada no planejamento das ações de saúde para grupos de trabalhadores e população geral.

    2014-09-01

    Full Text Available O estudo apresenta uma análise das interações entre o aluno com surdez, o professor e o intérprete em sala de aula, além do papel desses sujeitos no processo de inclusão do aluno surdo. Trata-se de uma pesquisa qualitativa realizada em 10 escolas públicas de Ensino Médio de Campo Grande-MS que receberam 24 alunos com surdez. Nessa análise utilizamos a abordagem histórico cultural de Vygotsky. Os resultados evidenciaram que apenas o intérprete interage efetivamente com esses alunos e pouco colabora para que eles interajam com pessoas que não dominam a Língua Brasileira de Sinais. Em sala de aula, o professor transfere ao intérprete a responsabilidade pelo ensino e a aprendizagem desses alunos.

    Full Text Available O objetivo deste trabalho é investigar a relação entre o dizer e o fazer do professor, no que tange à influência das novas tecnologias no ensino e aprendizagem de língua inglesa, bem como identificar os fatores que se articulam para o estabelecimento dessa relação. Para tanto, fazemos o confronto entre as crenças manifestadas no dizer do professor e as crenças depreendidas de seu fazer. Inserida numa perspectiva predominantemente qualitativa de cunho interpretativista, a pesquisa adota uma abordagem contextual de investigação de crenças de professores. O trabalho é fundamentado teoricamente em estudos que abordam as crenças de professores, o papel das novas tecnologias nos processos de ensino e aprendizagem de língua estrangeria, e a relação entre o professor reflexivo e a utilização das novas tecnologias. Os principais resultados encontrados apontam predominantemente para uma relação de dissonância entre o dizer e o fazer dos professores, e os fatores articuladores dessa relação se enquadram em quatro classes, a saber: fatores contextuais, experienciais, cognitivos e afetivos.

    Full Text Available Investiga-se, neste artigo, a política curricular da rede estadual de ensino fluminense, o Currículo Mínimo. Seguindo o caminho adotado por outros estados, o Rio de Janeiro adota medidas para reestruturar sua rede de ensino e melhorar os indicadores educacionais. Para esse fim, tem se apropriado de estratégias de responsabilização, estandardização, centralização do currículo e criação de seu próprio sistema de avaliação em larga escala. O presente estudo possui como questão central discutir as concepções dos professores sobre o Currículo Mínimo de Ciências. Esta análise estrutura-se na teoria das representações sociais e busca conhecer e explorar os elementos de maior centralidade no perfil identitário dos docentes sobre o currículo. O conteúdo da centralidade das representações sociais sugere que os professores vivem um momento de reajustes em sua prática. É fundamental desenvolver meios que deixem mais claros os objetivos da política. Deve-se implantar estratégias para capacitar os professores a lidar com a estrutura contemporânea dos currículos, baseada em habilidades e competências. É preciso que estas políticas sejam consolidadas com longevidade, com objetivos claros e pedagogicamente definidos, os quais sejam plenamente esclarecidos e justificados para aqueles que farão sua efetivação. Desta maneira, somente com o engajamento e a participação dos professores, pode-se pensar em políticas educacionais de fato transformadoras.

    Full Text Available Este trabalho discute a problemática que envolve o hábito da leitura na Educação Básica. Tem como objetivo discutir questões relacionadas às dificuldades de leitura bem como o papel da escola e dos professores na minimização do problema em questão. Com base em pesquisas e ensaios relevantes sobre o tema, explicita o tema a partir do conceito de leitura e sua utilização no cotidiano do aluno. Faz referência as estratégias de ensino da leitura como condição essencial ao desenvolvimento da competência leitora. Enfatiza o papel da escola enquanto instituição responsável formalmente e parcialmente pelo aprendizado cognitivo do aluno nas diferentes áreas do conhecimento, primando pela proficiência leitora. Apresenta como saída ao problema detectado o estímulo por parte da escola e desempenho de seus profissionais, em criar situações em que o aluno aprecie a importância da leitura, bem como mostrar a importância da formação contínua dos professores, a reflexão e avaliação de suas práticas pedagógicas.

    Renata Fernandes Mourão

    Full Text Available Buscou-se compreender a relação entre o sentido subjetivo da criatividade do professor e sua prática pedagógica com projetos. Partiu-se da teoria históricocultural da subjetividade desenvolvida por González Rey (1997, 1999, 2001, 2002b, 2004. O método adotado foi o estudo de caso com dois professores que trabalham com projetos de estratégia relativos ao ensino-aprendizagem em uma mesma escola. Vários instrumentos foram utilizados: a técnica de completamento de frases, redações, observação direta, análise documental e, principalmente, a entrevista como processo. Como conclusão principal, percebeu-se que se trata de uma relação recursiva. Além disso, a pesquisa demonstrou que os sentidos subjetivos de importantes aspectos contextuais - como o espaço em sala de aula - são mediadores da relação colocada sob foco. Por fim, notou-se que conflitos e contradições vividos na prática com projetos configuram-se como uma situação potencial de desenvolvimento em relação ao sentido subjetivo da criatividade e à própria prática docente.

    Full Text Available O artigo investiga os diferenciais de remuneração entre os professores dos diversos níveis de ensino, das redes pública e privada. Analisando somente os salários, os diferenciais são na maior parte dos casos favoráveis ao setor privado. Esta conclusão se altera quando se calcula o Valor Presente do Contrato de Trabalho. O VPCT leva em consideração toda a renda auferida pelo docente, incluindo os salários recebidos durante a vida ativa e também a aposentadoria. O VPCT do ensino público é sempre mais elevado que o VPCT privado. Também são calculadas as Taxas Internas de Retorno (TIRs da previdência social, cujos resultados mostram que os retornos do setor público são maiores que os do setor privado. Conclui-se que as diferentes regras de aposentadoria têm importância significativa nos rendimentos ao longo da vida dos docentes. Também se conclui que docentes da rede pública não recebem remuneração inferior a seus pares do setor privado.This paper studies the earnings differentials between public and private professors in the different levels of education. In most of the cases, there is a positive differential in favor of the private sector. This conclusion changes when we compute the Present Value of the Work Contract (PVWC. The PVWC considers all the income received during the workers life span. Here, we compute the present value of the wages received in the working life with the retirement benefits. The results show that the PVCW is higher in the public sector than in the private sector. We compute the internal rate of return (IRR of the retirement system. We conclude that different retirement rules between the two sectors have a huge impact in the professors´ life earnings with a public IRR higher than the private one. We also conclude that public teachers do not receive lower earnings than their private counterparts.

    Full Text Available Este artigo tem como objetivo uma melhor compreensão da relação que se estabelece entre os professores de instrumento (ou canto e os seus alunos no contexto da aula individual em Portugal e descobrir se esta relação tende a afetar o percurso pedagógico-musical dos alunos, verificando qual a possível ligação entre ambos. Para tal realizou-se um questionário a professores e outro a alunos, que foram distribuídos em quatro conservatórios portugueses. Os resultados foram analisados com o programa de estatística SPSS 19. Na discussão verificou-se que em Portugal tanto a maioria dos professores como dos alunos tem a perceção de partilhar uma relação satisfatória, afirmando os professores que se sentem realizados na sua profissão e os alunos que se sentem motivados e com confiança nos seus professores. Ambos concordam com a permissa que esta relação é de extrema importância para a boa evolução do aluno como músico, tal como os livros e estudos consultados para a base teórica deste artigo nos indicam.

    Full Text Available OBJETIVO: Identificar se existe correlação entre ruído ambiental no interior da sala de aula, intensidade da voz e presença de alteração vocal em professores. MÉTODOS: Foi realizada medição do ruído ambiental em dez salas de escolas municipais de ensino fundamental. A intensidade das vozes das professoras foi medida durante atividade de ensino. Amostras de vogal prolongada [é] e contagem de 1 a 20 emitidas pelas professoras foram analisadas utilizando escala GRBASI. Os resultados obtidos foram correlacionados. RESULTADOS: A média de ruído ambiental sem a presença das crianças em sala de aula variou de 40 a 51 dB(A e com a presença das crianças de 45 a 65 dB(A. Entre as professoras, houve 70% de ocorrência de vozes alteradas no grau geral (G e 90% com tensão na voz (S, variando entre graus discreto e moderado. Constatou-se variação entre 52 dB(A e 68 dB(A na intensidade da voz das professoras, atingindo 7,48 dB(A acima do nível do ruído ambiental. Houve correlação entre a intensidade vocal das professoras e ruído ambiental na presença das crianças durante a aula. CONCLUSÃO: Os níveis de ruído ambiental em sala de aula são altos e se correlacionam com o aumento da intensidade das vozes das professoras. Embora com alta ocorrência de vozes alteradas, não é possível correlacioná-las com o nível de ruído ambiental.PURPOSE: To explore the existence of correlations between environmental noise in classrooms, voice intensity and teacher's vocal problems. METHODS: Environmental noise was measured in 10 classrooms of municipal elementary schools; the intensity of teachers' voice was measured during teaching practice; teachers' speech samples containing emissions of sustained vowel [é] and counting from 1 to 20 were analyzed using the GRBASI protocol; and the results were tested for correlation.

Para tanto, participaram 20 professores da rede municipal de ensino de Parnaíba-PI, sendo que 75% são mulheres com a idade variando entre 23 aos 52 anos, os outros 25% restantes são homens com a idade variando entre 24 aos 45 anos de idade. Utilizou-se de um questionário sociodemográfico e do Teste de Associação Livre de Palavras com os estímulos indutores “Sexualidade” e “Educação Integral”. Os dados foram analisados através da técnica de rede semântica, considerando o tamanho e núcleo de rede, peso semântico e distância semântica quantitativa. Observou-se que os professores possuem uma ideia romântica do que seja a sexualidade não lhe atribuindo um cunho reflexivo, tão necessário na atualidade em que se vive, revestida de intolerância e preconceito. Ao se tratar da educação integral estes possuem uma compreensão positiva sobre esta e demonstram entender, que por meio dela, possa-se chegar a uma educação de qualidade. Assim, por meio do seguinte trabalho é possível compreender a importância da discussão desses temas e o quanto ainda precisam ser refletidos pelas instituições escolares como também pela sociedade como um todo, objetivando, dessa forma, se chegar a um ideal de educação.

    Full Text Available A fim de contribuir com a formação de professores da Educação Infantil para a Educação Inclusiva, neste artigo, tivemos como objetivo central descrever o modo como foi abordada a questão das dificuldades de aprendizagem e o impacto de um diagnóstico equivocado atribuído a uma criança em fase inicial de aprendizagem formal da escrita, em um dos encontros teórico-reflexivos empreendidosjunto a 43 professores de classes de Pré II, de dez escolas municipais de Educação Infantil, de um município do interior do Estado de São Paulo. Tal descrição foi norteada pelas etapas da abordagem colaborativa consideradas no subprojeto “Compreensão acerca do diagnóstico clínico da Dislexia e seu impacto no futuro escolar da criança matriculada em classes de Pré II da Educação Infantil”, desenvolvido como uma das etapas do projeto maior denominado “Despatologização da aprendizagem da escrita e Educação Inclusiva: reflexões e ações do professor de Educação Infantil”. Ao final, foi possível a identificação,mediante os relatos dos professores mencionados, da necessidade de ressignificação de suas vivências e experiências didáticas para a sistematização de novas ações direcionadas ao enfrentamento das dificuldades de aprendizagem que perpassam o processo de apropriação da escrita de parte dos alunos, o que poderá contribuir para a despatologização do ambiente escolar, na medida em que os professores poderão auxiliar seus alunos na construção deuma relação mais positiva com a escrita, em detrimento da adoção de procedimentos rígidos e restritos que não consideram a relação de cada sujeito com a escrita e as singularidades presentes em tal relação.

  20. A didática de Comênio: entre o método de ensino e a viva voz do professor

    Directory of Open Access Journals (Sweden)

    Douglas Emiliano Batista

    Full Text Available Resumo Neste artigo – o qual aprofunda concepções defendidas em tese de doutorado na Faculdade de Educação da Universidade de São Paulo – analisa-se se na Didática Magna, de Comênio, há lugar para a enunciação do professor. Para Comênio, em princípio, o método de ensino governa tão minuciosamente as ações do professor que este desponta como um mero executor anônimo de um plano didático decidido de antemão por eruditos. Com base na Psicanálise e Educação e em suas concepções de sujeito, enunciação e implicação com o saber, procurou-se colocar à prova se a concepção aqui expressa é de fato absoluta na Didática. Tal expediente permitiu trazer à baila uma importante antinomia comeniana, a qual gira em torno da proeminência do método de ensino e da imprescindibilidade da viva voz do professor. A partir de tal antinomia se concluiu que na Didática há lugar para a enunciação do professor, e o mestre não é reduzido a um executor anônimo do método.

    Full Text Available CONTEXTO: O diagnóstico de TDAH em crianças e adolescentes, segundo os critérios do DSM-IV, requer que os sintomas estejam presentes em, ao menos, dois ambientes distintos (principalmente escola e casa. Apesar da importância do relato de pais e professores, esse tema tem sido pouco investigado no Brasil. OBJETIVO: Investigar a concordância entre os relatos de pais e professores de uma amostra clínica de crianças e adolescentes com diagnóstico de TDAH. MÉTODOS: A amostra era composta por 44 crianças e adolescentes com idades variando entre 6 e 16 anos (40 meninos e 4 meninas, com diagnóstico clínico de TDAH. Foram comparadas as respostas de pais e professores no questionário SNAP-IV, visando a calcular taxas de concordância entre diferentes fontes de informação para sintomas de TDAH. RESULTADOS: Concordância para o diagnóstico de TDAH ocorreu em aproximadamente metade dos casos; pais relataram mais sintomas de TDAH que professores. CONCLUSÃO: Os achados aqui apresentados podem mostrar que informações acerca da sintomatologia de TDAH não são bem divulgadas para professores brasileiros, indicando a necessidade de se investir em sessões educacionais sobre o transtorno, tendo em vista a importância do relato de profissionais de educação para o diagnóstico de TDAH.BACKGROUND: ADHD diagnosis in children and adolescents according to DSM-IV criteria demands symptoms to be present in at least two different settings (mainly school and home.

    Full Text Available Em nosso trabalho buscamos entender a dinâmica que se estabelece na sala de aula quando são introduzidas atividades de grupos, analisando o processo grupal e sua relação com o ensino-aprendizagem da Física. Por isso, optamos por um estudo das relações estabelecidas no grupo entre os seus membros (alunos e professor e das estratégias criadas em conjunto para a resolução da atividade. Como referencial teórico, utilizamos as concepções de grupo operativo de Pichon-Rivière, que focaliza a tarefa do grupo e o vínculo entre os membros como elementos essenciais do desenvolvimento grupal. O nosso trabalho consistiu em uma análise diacrônica e sincrônica das interações dos alunos de um dos grupos que compunha a classe em duas aulas diferentes: a primeira antes de uma intervenção institucional do professor, que atribuiu funções para cada um dos membros do grupo; e a segunda depois desta intervenção.This work aims to understand the dynamics that is established in the classroom when group activities are introduced. Our main focus is in understanding of group processes and their relation to the Physics teaching and learning. We studied the relations established in the group between their members and the strategies used during the activity in a Physics classroom in High School. For this work we used the conceptions of "operative groups" as described by Pichon-Rivière, who focuses on the task of the group and on the bonds between its members as essential elements in the group's development. Our work consists of an analysis of the interactions at two different moments for the group: the first one before a teacher’s initial intervention that gave specific functions to each member of the group, and the second one after this intervention.

    Full Text Available É possível haver horizontalidade entre a formação de professores e a formação dos alunos? Como se explicita a horizontalidade entre as práticas de ensino dos professores e as práticas de aprendizagem de alunos no que se refere à leitura e ao uso das tecnologias e mídias na educação? Este artigo descreve a experiência desenvolvida entre os anos 2007 e 2009 no projeto TIME (Tecnologias e Mídias Interativas na Escola. Nesse projeto, a Unicamp e duas escolas municipais de Hortolândia (SP vivenciaram a experiência de recusar a verticalização ao apostar que alunos e professores aprendem e se formam mediante as múltiplas possibilidades de conexão entre saberes e conhecimentos. A opção teórica do estudo converge a metáfora do rizoma, multiplicidades, linhas e conexões. A experiência de formação aqui será lida, portanto, como um texto em sua tessitura e um mapa em seu devir. A metodologia de investigação pautou-se no registro escrito e imagético dos encontros de formação, nos relatórios e, posteriormente, nos artigos de professores e estudantes contidos nos livros digital e impresso Tecnologias e Mídias Interativas na Escola: Projeto TIME, datados de 2010 e 2011.

    Sarcoidosis is one of the leading causes of inflammatory eye disease. Ocular sarcoidosis can involve any part of the eye and its adnexal tissues, and may cause uveitis, episcleritis/scleritis, eyelid abnormalities, conjunctival granuloma, optic neuropathy, lacrimal gland enlargement and orbital inflammation. Glaucoma and cataract can be complications from inflammation itself or adverse effects from therapy. Ophthalmic manifestations can be isolated, or associated with other organ involvement. Patients with ocular sarcoidosis can present with a wide range of clinical presentations and severity. Multi-disciplinary approaches are required to achieve the best treatment outcomes for both ocular and systemic manifestations. PMID:26593141

MÉTODOS: Realizou-se levantamento entre professores do ensino fundamental de escolas públicas do município de Campinas/SP, que atuavam com alunos que apresentavam visão subnormal, no ano letivo de 1999. Foram incluídas 23 escolas onde se localizava essa população. Foi utilizado questionário auto-aplicável como instrumento de coleta de dados. RESULTADOS: De 84 professores, 68 (81% responderam ao questionário. A média de tempo de experiência profissional de magistério era de 20,8 anos. A maioria (92,6% não relatou formação na área da deficiência visual. Em relação ao conhecimento sobre os sinais e sintomas indicativos de dificuldade visual, a maioria indicou a dificuldade para ler na lousa (94,1%, seguida da cefal��ia (89,7% e a aproximação exagerada dos objetos aos olhos (88,2%. Desses professores, 55,9% identificaram alunos que apresentavam dificuldades visuais. Entre os que declararam ter identificado esses alunos, 84,2% proveram orientações ao escolar e 63,2% aos familiares para encaminhamento do problema. Somente 26,3% orientaram o aluno a procurar o oftalmologista. CONCLUSÃO: Os professores apresentaram conhecimento insuficiente quanto à saúde ocular e, portanto, as ações desenvolvidas não foram completas e abrangentes. Sugere-se a implantação de um programa de saúde ocular em todo o sistema público de ensino, visando desenvolver ações de prevenção da incapacidade visual, promoção e recuperação da saúde ocular.

    Full Text Available Intra-ocular straylight can cause decreased visual functioning, and it may cause diminished vision-related quality of life (VRQOL. This cross-sectional population-based study investigates the association between straylight and VRQOL in middle-aged and elderly individuals. Multivariable linear regression analyses were used to assess the association between straylight modeled continuously and cutoff at the recommended fitness-to-drive value, straylight ≥ 1.4 log(s, and VRQOL. The study showed that participants with normal straylight values, straylight ≤ 1.4 log(s, rated their VRQOL slightly better than those with high straylight values (straylight ≥ 1.4 log(s. Furthermore, multivariable regression analysis revealed a borderline statistical significant association ( p = .06 between intra-ocular straylight and self-reported VRQOL in middle-aged and elderly individuals. The association between straylight and self-reported VRQOL was not influenced by the status of the intra-ocular lens (natural vs. artificial intra-ocular lens after cataract extraction or the number of (instrumental activities of daily living that were reported as difficult for the elderly individuals.

Um teste, em lápis e papel, composto de 3 questões foi elaborado e aplicado com 287 estudantes e professores brasileiros, dos quais: 54 eram alunos da 4ª série e 47 eram da 5ª série do ensino fundamental, 61 eram estudantes iniciantes e 82 eram estudantes concluintes do curso de pedagogia, e 43 eram professores das séries iniciais do ensino fundamental. O teste foi aplicado de forma coletiva, em sala de aula. Excetuando-se o grupo de professores, todos os grupos tendem a confundir média com adição dos valores ou com o valor máximo. Os resultados mostram que, apesar da evolução no entendimento do conceito de média em relação ao nível de escolaridade, algumas confusões ainda são identificadas entre o grupo de professores.The present study aims to analyze students and teachers conceptions and misconceptions of average. A paper and pencil test, comprised of three questions, was designed. 287 Brazilian students and teachers undertook the test. They were: 54 pupils from 4th grade, 47 from 5th grade, 61 students beginning undergraduation on Pedagogy, 82 students finishing their undergraduation on Pedagogy and 43 elementary school teachers. The test was undertaken in a collective way. Excepting to the teachers group, all the groups tend to confuse average to addition of the values, or to the maximum value. The result points that, in spite of an evolution on the understanding of the concept of average according to the educational level of the groups, some misconceptions are found within the teachers' group.

    Full Text Available Este estudo tem como objetivo principal apresentar a importância da formação de professores para a Educação Infantil, valorizando a integração entre a educação e o cuidado como função precípua no trabalho com crianças pequenas, como também pretende refletir sobre a importância da atuação do professor em processos de cultivo diálogo com a criança. Apesar de vivermos em uma sociedade contemporânea com mudanças legais que passam a considerar a criança como um sujeito de direitos é preciso refletir acerca das especificidades do fazer docente para esse momento tão especial da infância. Considera-se que as crianças que fazem parte das Instituições de Educação Infantil estão numa fase importante de suas vidas em que dependem intensamente dos adultos, sendo necessário auxiliá-las nas atividades que não conseguem realizar sozinhas, atendendo-as em suas necessidades básicas de segurança, nutrição, higiene, afeto e saúde e para tanto a atuação do professor mediador é essencial. Assim, o desafio que se estabelece quando o intuito é pensar a formação dos Professores da Infância é apresentar as especificidades da docência em Educação Infantil, como também as questões que envolvem a valorização desse profissional buscando uma relação dialógica comprometida com o desenvolvimento pleno da criança.

    Full Text Available La evolución etiológica de la medicina la podemos dividir en dos grandes períodos: período de la sífilis y período de la tuberculosis. El período de la sífilis, gracias a las armas de combate de que hoy disponemos, ocupa un lugar secundario. El período de la tuberculosis y que no es sino el paralelo de la vida moderna, ocupa en vigencia el primer lugar. Es el período presente. Hasta hace poco tiempo el médico en general, iniciaba la exploración de su paciente con un interrogatorio, una inspección, un tacto y una serología con una obsesión sifilítica. En la época actual el médico y en especial el oftalmólogo debe tener una obsesión tuberculosa en la investigación etiológica. Cuántas veces en una afección ocular que de una manera lenta pero progresiva produce profundas alteraciones oculares, lleva el sello soterrado de una tuberculosis? Cuántos enfermos de una constitución en apariencia envidiable hacen precisamente por un exceso de sus defensas una alergia tuberculosa? Tan traicionera como la sífilis es la tuberculosis. La sífilis quema sus etapas y estalla con una hemorragia cerebral, una locura, una parálisis general, una ataxia locomotriz progresiva, una goma o una meningitis sifilítica. La tuberculosis hace su presentación con una afección ocular, una goma, una granulia, una artritis, una osteítis, o una meningitis óptico-quiasmática. Siendo esto así, es necesario, en la mayoría de las afecciones oculares, tratar de identificarla por los medios de diagnóstico de que hoy disponemos.

    Full Text Available Resumo: Novos conhecimentos científicos e tecnológicos da biologia molecular estão cada vez mais presentes na sociedade, tornando-se necessária a educação científica dos cidadãos. Este artigo analisa os discursos de professores sobre a manipulação genética e o melhoramento humano no contexto de um curso de formação continuada sobre o movimento eugênico ocorrido nos séculos 19 e 20. Os dados, coletados por meio de videogravação, foram transcritos e analisados pela metodologia de Análise de Discurso. Os resultados apontam para uma mudança gradual nos posicionamentos dos professores. No início, os sujeitos apresentam uma visão mais determinista ao aludirem que, por meio da genética, é possível aperfeiçoar a espécie humana. Todavia, ao longo das discussões, observa-se a construção de uma percepção mais contextualizada da ciência e da tecnologia, permeada de influências ideológicas da sociedade e questionamentos acerca das consequências da manipulação genética e da divulgação de padrões humanos idealizados.

    Full Text Available Este texto apresenta resultados de pesquisa sobre a percepção da homossexualidade, a partir da análise das respostas a um questionário, com questões abertas, aplicado a 67 participantes do Grupo de Estudos sobre Educação Sexual (GEES da Universidade Estadual de Londrina, constituído por professores/as da rede pública de ensino. A análise do conteúdo se deu a partir da organização do material em núcleos de sentido que denotavam valores de referência e modelos de comportamento acerca da homossexualidade. As categorias temáticas utilizadas foram o inato e o adquirido. A primeira inclui a percepção da homossexualidade como algo a priori, de natureza biológica, pulsional ou comportamental; a segunda implica perceber a homossexualidade como decorrente do “meio ambiente”, da “educação familiar” ou como “opção” do indivíduo. Além dessas categorias, utilizamos também os conceitos de tempo longo, vivido e curto para analisar a construção histórica dos significados sociais atribuídos à homossexualidade

    Full Text Available Previous studies have shown ocular haemorrhages in choline-deficient rats. The aim of this paper is to study further the relationship between ocular and renal lesions and biochemical alterations in rats fed a choline-deficient diet. Fifty one weanling male Wistar rats, were divided into two groups. Thirty one of them were fed a choline-deficient diet and the rest was fed a choline-supplemented diet ad libitum. Animals from both groups were killed between the fifth and the eighth day. Urea, creatinine and homocysteine concentrations in blood were determined. Eyes were used for light microscopy study; high resolution light microscopy and the study of the retina as "rétine a plat". Kidneys were studied by light microscopy. Choline-supplemented rats did not show ocular or renal lesion. Choline-deficient rats that showed renal lesions, tubular or cortical necrosis, did not always have ocular changes. There were no ocular changes in the only choline-deficient rat without renal lesion. The ocular changes consisted mainly in haemorrhage in both cameras and ciliary and vitreous bodies. Correlations between ocular and renal lesion (r=0.72, pEstudios previos han demostrado hemorragia ocular en ratas deficientes en colina.

    To present the visual outcomes and ocular sequelae of victims of cluster bombs. This retrospective, multicenter case series of ocular injury due to cluster bombs was conducted for 3 years after the war in South Lebanon (July 2006). Data were gathered from the reports to the Information Management System for Mine Action. There were 308 victims of clusters bombs; 36 individuals were killed, of which 2 received ocular lacerations and; 272 individuals were injured with 18 receiving ocular injury. These 18 surviving individuals were assessed by the authors. Ocular injury occurred in 6.5% (20/308) of cluster bomb victims. Trauma to multiple organs occurred in 12 of 18 cases (67%) with ocular injury. Ocular findings included corneal or scleral lacerations (16 eyes), corneal foreign bodies (9 eyes), corneal decompensation (2 eyes), ruptured cataract (6 eyes), and intravitreal foreign bodies (10 eyes). The corneas of one patient had extreme attenuation of the endothelium. Ocular injury occurred in 6.5% of cluster bomb victims and 67% of the patients with ocular injury sustained trauma to multiple organs. Visual morbidity in civilians is an additional reason for a global ban on the use of cluster bombs.

    Full Text Available Este estudo evidencia por meio das vozes dos professores que, embora a prisão seja apontada como espaço de reeducação e ressocialização do homem privado de liberdade, ao construir uma experiência ancorada no exercício autoritário do poder e da dominação, ela acaba por constituir-se, em uma organização cujas relações se socializam na delinqüência. Entre o discurso oficial e o modo de vida instaurado pelas práticas de ressocialização próprias da prisão, estabelecese um hiato: embora se pretenda a humanização do tratamento, incluindo-se neste a educação escolar, as técnicas adotadas põem à mostra seu lado reverso. Os professores participantes da pesquisa, um estudo de caso, que se desenvolveu em presídio masculino, do interior do estado de São Paulo/Br., mostram ter clareza de que a meta da reabilitação tem permanecido, no nível verbal, e evidenciam através de suas falas, que o elemento fundamental da eficácia de seu papel reside noprocesso de resgate da liberdade, e a escola é uma das instituições que melhor cumpre a tarefa de oferecer possibilidades que libertam e unem, ao mesmo tempo. Embora o quadro que se apresentanão seja alentador, dada à falta de transparência das organizações penitenciárias e o hiato entre o discurso oficial e o modo de vida instaurado no espaço prisional que dificultam possíveis melhorias,alguns passos podem ser dados, visto que muitos dos problemas existentes no interior da escola das unidades prisionais têm semelhanças com os de outros espaços escolares.Abstract This paper highlights, through the teacher’s voices, that although prison is pointed out to be a space of reeducation and ressocialization of men in situation of lack of freedom , it is built upon an experience of authoritarian practice of power and domination that results in being an organization whose relations are socialized in delinquency.

    Full Text Available En los últimos años se ha producido un extraordinario avance en los conocimientos relacionados con diferentes ramas biomédicas, entre ellas, la biología celular. Esto ha dado un notable impulso a una nueva rama de la medicina denominada medicina regenerativa. Esta nueva disciplina médica se basa fundamentalmente en los nuevos conocimientos sobre las células madre y en su capacidad de convertirse en células de diferentes tejidos. Una de las estructuras que tiene más interés, desde el punto de vista de la medicina regenerativa, es la superficie ocular. Por esto, se ha logrado notables progresos en la reconstrucción de la superficie ocular mediante la aplicación de procederes regenerativos. Los cultivos de células del epitelio corneal humano están siendo utilizados en el tratamiento de la insuficiencia limbar. Esto permite disminuir la incidencia de opacidades tipo Haze tras queratectomía fotorrefractiva, acelerar la curación y evitar la aparición de leucomas en pacientes con defectos epiteliares persistentes e intentar disminuir la incidencia de opacidades corneales en pacientes sometidos a queratectomía fototerapéutica por diferentes distrofias corneales.In the last few years, an extraordinary advance has taken place in the knowledge about several biomedical branches as is the case of cellular biology, which has remarkably encouraged the development of a new medical branch called regenerative medicine.

    Ocular recognition is a new area of biometric investigation targeted at overcoming the limitations of iris recognition performance in the presence of non-ideal data. There are several advantages for increasing the area beyond the iris, yet there are also key issues that must be addressed such as size of the ocular region, factors affecting performance, and appropriate corpora to study these factors in isolation. In this paper, we explore and identify some of these issues with the goal of better defining parameters for ocular recognition. An empirical study is performed where iris recognition methods are contrasted with texture and point operators on existing iris and face datasets. The experimental results show a dramatic recognition performance gain when additional features are considered in the presence of poor quality iris data, offering strong evidence for extending interest beyond the iris. The experiments also highlight the need for the direct collection of additional ocular imagery.

    Dear readers and authors, June 3, 2012 will mark five months since Professor Igor Yevseyev, Deputy Editor-in-Chief of both journals Laser Physics and Laser Physics Letters passed away, suddenly and unexpectedly. He was 67. Born in Moscow, he entered one of the world's best schools of physics, Moscow Engineering Physics Institute (MEPhI). With this renowned educational and research institution he bonded an alliance for his entire life, starting as an undergraduate student in the Department of Theoretical Physics and later continued as graduate student, assistant professor, associated professor, and full professor in the same department, a rare accomplishment of a person. All those years he retained the love of his life—the love for physics. He worked tirelessly as a teacher and scholar in this captivating field of knowledge. Professor Yevseyev was one of the founders of the international journal of Laser Physics in 1990, the first academic English language journal published in the former USSR. Later, in 2004, the second journal, Laser Physics Letters was brought to the forum of global laser physics community. The idea behind this new title was Professor Yevseyev's initiative to reach the readers and participants with new pioneering and break-through research results more rapidly. His leadership and indefatigable dedication to the quality of published materials made it possible that this journal reached international recognition in a few short years. Still, in order to attract even more attention of potential contributors and readers, Professor Yevseyev originally proposed to conduct the International Laser Physics Workshop (LPHYS) on the annual basis. Since 1992 the Workshop has been conducted every year, each year in a different country. As in all previous years, Professor Yevseyev was the key organizer of this year's workshop in Calgary, Canada. Sadly, this workshop will take place without him. Editorial Board

    Professor Steven L. Wechsler, a world-renowned eye researcher and virologist, passed away unexpectedly on June 12, 2016 at the age of 68. Many scientists came to know Professor Wechsler as a gifted researcher in the field of ocular Herpes Simplex Virus (HSV-1) latency, reactivation, and pathogenesis. Professor Wechsler published over 150 peer-reviewed scientific papers during his career, pushing forward the frontiers of his field eye research. His colleagues would say, 'Steve literally wrote the book on herpes latency and reactivation.' He was the first to show that the HSV-1 latency-associated transcript (LAT) is essential for the HSV-1 high spontaneous reactivation phenotype and that LAT has anti-apoptosis activity. This discovery of LAT's anti-apoptosis activity, which is a key factor in how the LAT gene enhances reactivation, was published in Science in 2000 and created a new paradigm that greatly increased understanding of HSV-1 latency and reactivation. In collaboration with Professor Lbachir BenMohamed, an immunologist, they later demonstrated that LAT also acts as an immune evasion gene. He was a caring scientist who truly enjoyed working and sharing his experience and expertise with young researchers. He will be remembered as a significant pillar within scientific and ocular herpes research communities worldwide. Professor Wechsler's dedication to science, his compassionate character, and wonderful sense of humor were exemplary. We, who were his friends and colleagues, will mourn his passing deeply.

  4. Professor Igor Yevseyev: In Memoriam

    2012-01-01

    Dear readers and authors, June 3, 2012 will mark five months since Professor Igor Yevseyev, Deputy Editor-in-Chief of both journals Laser Physics and Laser Physics Letters passed away, suddenly and unexpectedly. He was 67. Born in Moscow, he entered one of the world's best schools of physics, Moscow Engineering Physics Institute (MEPhI). With this renowned educational and research institution he bonded an alliance for his entire life, starting as an undergraduate student in the Department of Theoretical Physics and later continued as graduate student, assistant professor, associated professor, and full professor in the same department, a rare accomplishment of a person. All those years he retained the love of his life—the love for physics. He worked tirelessly as a teacher and scholar in this captivating field of knowledge. Professor Yevseyev was one of the founders of the international journal of Laser Physics in 1990, the first academic English language journal published in the former USSR. Later, in 2004, the second journal, Laser Physics Letters was brought to the forum of global laser physics community. The idea behind this new title was Professor Yevseyev's initiative to reach the readers and participants with new pioneering and break-through research results more rapidly. His leadership and indefatigable dedication to the quality of published materials made it possible that this journal reached international recognition in a few short years. Still, in order to attract even more attention of potential contributors and readers, Professor Yevseyev originally proposed to conduct the International Laser Physics Workshop (LPHYS) on the annual basis. Since 1992 the Workshop has been conducted every year, each year in a different country. As in all previous years, Professor Yevseyev was the key organizer of this year's workshop in Calgary, Canada. Sadly, this workshop will take place without him. Editorial Board

    Ocular tuberculosis is an extrapulmonary tuberculous condition and has variable manifestations. The purpose of this review is to describe the clinical manifestations of ocular tuberculosis affecting the anterior and posterior segments of the eye in both immunocompetent and immunocompromised patients. Review of literature using Pubmed database. Mycobacterium tuberculosis may lead to formation of conjunctival granuloma, nodular scleritis, and interstitial keratitis. Lacrimal gland and orbital caseating granulomas are rare but may occur. The intraocular structures are also a target of insult by M. tuberculosis and may cause anterior granulomatous uveitis, anterior and posterior synechiae, secondary glaucoma, and cataract. The bacillus may involve the ciliary body, resulting in the formation of a localized caseating granuloma. Posterior segment manifestations include vitritis, retinal vasculitis, optic neuritis, serpiginous-like choroiditis, choroidal tubercules, subretinal neovascularization, and, rarely, endophthalmitis. The recognition of clinical signs of ocular tuberculosis is of utmost importance as it can provide clinical pathway toward tailored investigations and decision making for initiating anti-tuberculosis therapy.

    Objectives: To investigate the prevalence of ocular injuries in a large population of boxers over a period of 16 years, in particular, the most severe lesions that may be vision threatening. Methods: Clinical records of the medical archive of the Italian Boxing Federation were analysed. A total of 1032 boxers were examined from February 1982 to October 1998. A complete ophthalmological history was available for 956, who formed the study population (a total of 10 697 examinations). The following data were collected: age when started boxing; duration of competitive boxing career (from the date of the first bout); weight category; a thorough ocular history. The following investigations were carried out: measurement of visual acuity and visual fields, anterior segment inspection, applanation tonometry, gonioscopy, and examination of ocular fundus. Eighty age matched healthy subjects, who had never boxed, formed the control group. Results: Of the 956 boxers examined, 428 were amateur (44.8%) and 528 professional (55.2%). The median age at first examination was 23.1 (4.3) years (range 15–36). The prevalence of conjunctival, corneal, lenticular, vitreal, ocular papilla, and retinal alterations in the study population was 40.9% compared with 3.1% in the control group (p⩽0.0001). The prevalence of serious ocular findings (angle, lens, macula, and peripheral retina alterations) was 5.6% in boxers and 3.1% in controls (NS). Conclusions: Boxing does not result in a higher prevalence of severe ocular lesions than in the general population. However, the prevalence of milder lesions (in particular with regard to the conjunctiva and cornea) is noteworthy, justifying the need for adequate ophthalmological surveillance. PMID:15665199

    Full Text Available The present article discusses the teaching ethos of professors who are recognized for their good practice as trainers. The aim of our study is to analyze the influences of such professors’ professional constitution, as well as the explicit and/or tacit teaching knowledge they mobilize in their teaching practices. Based on Shulman, Gauthier, Tardif and Polanyi, we conducted interviews with three professors described by their students as reference. They were also observed in their classes, in the context of an undergraduate program in pedagogy at a public university. Data show similarities between the practices of the investigated professors, as well as a consistent description of their didactics, which is marked by intellective, moral, emotional and behavioral features.

  14. Ocular manifestations of leptospirosis

    Directory of Open Access Journals (Sweden)

    Rathinam S

    2005-01-01

    Full Text Available Leptospiral uveitis is a common entity in tropical countries. Ocular manifestations are noted in the second phase of illness, but these remain under-diagnosed mainly because of the prolonged symptom-free period that separates the systemic manifestations from detection of ocular manifestations.Varying ophthalmic presentations and the intrinsic nature of different types of uveitis to mimic one another also challenge the accuracy of the diagnosis. Of the individual ocular signs, the combination of acute, non-granulomatous, panuveitis, hypopyon, vasculitis, optic disc edema, membranous vitreous opacities and absence of choroiditis or retinitis have high predictive value for the clinical diagnosis of leptospiral uveitis. Geographic location of the patient, occupation, socio-economic status, risk factors related to exposure, past history of fever or jaundice also aid in diagnosis.Steroids are the mainstay of treatment for leptospiral uveitis. Depending upon the severity and anatomical location of inflammatory lesion, topical, peri-ocular and/or systemic steroids are given. The prognosis is generally good, even when the inflammation is severe.

    OBJECTIVES: To describe the clinical characteristics of ocular injuries sustained in hurling in the south of Ireland and to investigate reasons for non-use of protective headgear and eye wear. METHODS: Retrospective review of the case notes of 310 patients who attended Cork University Hospital or Waterford Regional Hospital between 1 January 1994 and 31 December 2002 with ocular injuries sustained during a hurling match. A confidential questionnaire on reasons for non-use of protective headgear and eye wear was completed by 130 players. RESULTS: Hurling related eye injuries occurred most commonly in young men. Fifty two patients (17%) required hospital admission, with hyphaema accounting for 71% of admissions. Ten injuries required intraocular surgical INTERVENTION: retinal detachment repair (5); macular hole surgery (1); repair of partial thickness corneal laceration (1); repair of globe perforation (1); enucleation (1); trabeculectomy for post-traumatic glaucoma (1). Fourteen eyes (4.5%) had a final best corrected visual acuity (BCVA) of <6\\/12 and six (2%) had BCVA <3\\/60. In the survey, 63 players (48.5%) reported wearing no protective facemask while playing hurling. Impairment of vision was the most common reason cited for non-use. CONCLUSIONS: Hurling related injury is a significant, and preventable, cause of ocular morbidity in young men in Ireland. The routine use of appropriate protective headgear and faceguards would result in a dramatic reduction in the incidence and severity of these injuries, and should be mandatory.

    To review the epidemiology, diagnosis and changing treatment paradigm of ocular candidiasis, and report current prevalence rates and risk factors at one inpatient hospital. Retrospective review; systematic literature review. All Wills Eye Institute inpatient ophthalmology consultations from Thomas Jefferson University Hospital were retrospectively reviewed between June 2006 and November 2006. All consultations for candidaemia were included. The outcome variables included chorioretinitis, endophthalmitis, visual symptoms and Candida speciation. The ophthalmic literature was reviewed using PubMed. Keywords included Candida, candidaemia, chorioretinitis, vitritis and endophthalmitis. Bibliographies were manually searched. Three of the 38 consultations for candidaemia (7.9%) had chorioretinitis. There were no cases of vitritis or endophthalmitis. The presence of symptoms, or the inability to articulate symptoms, was significantly associated with risk of ocular candidiasis (p = 0.003). All three cases of chorioretinitis had positive blood cultures for Candida albicans (p = 0.089) and were treated with oral fluconazole. Various factors have led to the increasing prevalence of inpatient candidaemia. Risk factors for ocular involvement include albicans species and the presence of, or inability to articulate, visual symptoms. For those without abnormal findings on initial examination, a subsequent retinal examination should be performed in 2 weeks, particularly if new symptoms develop or if the patient is unable to relay symptoms. Patients with chorioretinitis should be treated with systemic antifungal agents. For those with vitritis or endophthalmitis, particularly if worsening on systemic therapy alone, intravitreal antifungal medications or early vitrectomy should be considered.

The details of patients regarding age, gender, literacy, cause of injury and its effects on eye were entered into specially-designed performa. Sample selection consisted of all patients with history of ocular trauma and who were admitted to hospital. Population details consisted patients who were referred to the hospital from all parts of N.W.F.P. Thus, the frequency of trauma in the hospital admissions was analysed. Ophthalmic trauma comprised 6.78% of the hospital admission. One thousand one hundred and five patients presented with eye injuries. Out of them, 21 patients suffered from trauma to both eyes. Almost 80% patients were male and 69% patients were below 30 years of age. Delayed presentation was more common and 63.61% patients presented after one week. Open globe injuries were more common (520 eyes (46.18%)) than closed globe injuries (484 eyes (42.98%)). 23.26% of open globe injuries were associated with intraocular and intra-orbital foreign bodies. Superficial non-perforating, eyelid and adnexal and burns were seen in 122 eyes (10.83%). Among the complications, lens damage and hyphema was seen in more than 50% of the patients, 16.60% eyes were infected at the time of admission and 4.88% of eyes needed enucleation or evisceration. The common causes of injury were violence in 37.37%, occupational in 24.43% and domestic accidents in 19.18%. Ophthalmic trauma is a major public health problem. Majority of the involved are male and under 30 years of age. Delayed presentation is more common. Open globe injuries are more frequent. Violence and occupational injuries are the major causes.

    Full Text Available The most frequent primary headaches, including migraine variants, and intrinsic optic nerve disorders that produce headache, are reviewed. The latter are often accompanied by autonomic nervous system alterations which lead to vasomotor changes, frequently present in neuralgic processes known as headaches with disautonomic involvement. Epidemiological, semiological, clinical, and therapeutical aspects of different cranial, facial and ocular diseases that produce headache are included. Some physiopathological elements that may help to analyze painful craniofacial processes are discussed. Secondary headaches and common facial neuralgias, on the other hand, are also considered because they may confuse the differential diagnosis. Se revisan las cefaleas primarias más frecuentes que comprometen las estructuras oculares y vecinas al globo ocular, las variantes de la migraña y las alteraciones propias del nervio óptico que alteran la función visual y que se acompañan no solamente de síntomas dolorosos sino también de trastornos vasomotores debidos a alteraciones del sistema nervioso autónomo que suelen ser comunes en algunos procesos neurálgicos llamados ahora cefaleas con compromiso disautonómico. En este artículo se comentan los elementos epidemiológicos de las diferentes enfermedades craneales, faciales y oculares que cursan con cefalea; las diferencias clínicas entre las mismas y su presentación semiológica, al igual que algunos elementos terapéuticos. Se discuten además algunos elementos fisiopatológicos de gran utilidad en el análisis de los procesos dolorosos craneofaciales y el perfil temporal de los mismos; también se comentan algunas cefaleas secundarias que comparten con las primarias elementos que se prestan a confusión en la clínica. Finalmente, se hace un análisis de las neuralgias faciales comunes.

The foundations and referentials of ocular movements are then examined: the concepts of axes and planes, of the centers of mass and of rotation, of monocular displacements of translation and rotation, of binocular version and vergence displacements. The functions of centers of command for voluntary or reflex ocular movements are also presented, as well as the innervation of extrinsic ocular muscles. In a second part (physiology of the extrinsic ocular muscles, activities of contraction or relaxation and the importance of Sherrington's law are commented. The concepts of primary position of gaze and of the referentials for rotations are retaken leading to the diversity of the several systems of measurements. There follows analysis of the rotational actions of the ocular muscles, based on the so-called planes of muscular actions and on the anatomic distribution of the muscles, leading to the results in primary position of gaze and others. The effects of fascias and intermuscular membranes are also commented. Conclusively the modern concept of the muscular actions is presented (simultaneous actions of all muscles in each ocular position. Based on the conditions of Hering's law the concept of positions for the diagnosis of the oculomotor disfunctions, which differs from the classical one is developed: the muscles are considered in pairs, according to

    The eye is an easily accessible, highly compartmentalised and immune-privileged organ that offers unique advantages as a gene therapy target. Significant advancements have been made in understanding the genetic pathogenesis of ocular diseases, and gene replacement and gene silencing have been implicated as potentially efficacious therapies. Recent improvements have been made in the safety and specificity of vector-based ocular gene transfer methods. Proof-of-concept for vector-based gene therapies has also been established in several experimental models of human ocular diseases. After nearly two decades of ocular gene therapy research, preliminary successes are now being reported in phase 1 clinical trials for the treatment of Leber congenital amaurosis. This review describes current developments and future prospects for ocular gene therapy. Novel methods are being developed to enhance the performance and regulation of recombinant adeno-associated virus- and lentivirus-mediated ocular gene transfer. Gene therapy prospects have advanced for a variety of retinal disorders, including retinitis pigmentosa, retinoschisis, Stargardt disease and age-related macular degeneration. Advances have also been made using experimental models for non-retinal diseases, such as uveitis and glaucoma. These methodological advancements are critical for the implementation of additional gene-based therapies for human ocular diseases in the near future.

    Full Text Available Faiz I Shakarchi1,21Ibn Al-Haetham Teaching Eye Hospital, 2Department of Opthalmology, Medical College, Al-Mustansiriya University, Baghdad, IraqAbstract: The World Health Organization currently estimates that nearly two billion people, or one-third of the world’s population, are infected by tuberculosis, and that roughly 10% of the infected people are symptomatic. Tuberculosis affects the lungs in 80% of patients, while in the remaining 20% the disease may affect other organs, including the eye. Uveitis can be seen concurrently with tuberculosis, but a direct association is difficult to prove. Ocular tuberculosis is usually not associated with clinical evidence of pulmonary tuberculosis, as up to 60% of extrapulmonary tuberculosis patients may not have pulmonary disease. The diagnosis of tuberculous uveitis is often problematic and in nearly all reported cases, the diagnosis was only presumptive. Tuberculous uveitis is a great mimicker of various uveitis entities and it can be considered in the differential diagnosis of any type of intraocular inflammation. It is still unknown if ocular manifestations result from a direct mycobacterium infection or hypersensitivity reaction and this is reflected on the management of tuberculous uveitis. Prevalence of tuberculosis as an etiology of uveitis may reach up to 10% in endemic areas. Tuberculous uveitis is a vision-threatening disease that inevitably leads to blindness if not properly diagnosed and treated. The aim of this review is to illustrate the various clinical features and management of presumed tuberculous uveitis. The current review focuses on the diagnostic criteria, significance of tuberculin skin test, and use of systemic corticosteroids in the management of tuberculous uveitis as recommended in recent publications.Keywords: tuberculosis, uveitis, choroiditis, tuberculin skin test

    Full Text Available A motivação é fundamental para o envolvimento dos estudantes na escola. Para a teoria da autodeterminação, o estilo motivacional do professor, que pode controlar ou promover a autonomia, contribui para fomentar a ocorrência de tipos qualitativamente diferenciados de motivação. Neste estudo, de natureza exploratória, foram analisadas as interações entre dois professores e seus alunos. A amostra foi composta de acordo com o desempenho de 39 professores na avaliação do estilo motivacional, mediante a aplicação de um instrumento de autorrelato, problemas na escola. Desse total, dois professores, um com estilo motivacional promotor de autonomia e outro com uma orientação para o controle, tiveram suas aulas observadas em sete sessões, com o objetivo de levantar dados para a elaboração de um protocolo que continha categorias de interações. Foram então realizadas outras sete sessões de observação. Os resultados indicaram que, apesar de terem sido encontradas diferenças entre os desempenhos na avaliação do estilo motivacional, os professores interagiram com seus alunos de modo preferencialmente controlador. No entanto, o professor que promovia a autonomia interagiu de modo menos controlador no gerenciamento do tempo destinado para a realização das atividades em classe quando comparado ao professor controlador, além de oferecer feedback informativo. As implicações educacionais dos resultados são analisadas.

    Myasthenia gravis (MG) is a disease that affects the neuro-muscular junction resulting in classical symptoms of variable muscle weakness and fatigability. It is called the great masquerader owing to its varied clinical presentations. Very often, a patient of MG may present to the ophthalmologist given that a large proportion of patients with systemic myasthenia have ocular involvement either at presentation or during the later course of the disease. The treatment of ocular MG involves both the neurologist and ophthalmologist. Thus, the aim of this review was to highlight the current diagnosis, investigations, and treatment of ocular MG.

    Ludwig von Mises

    2009-01-01

    Full Text Available This memorandum was written at the request of Henry Hazlitt to provide Mises’s comments on and concerns about F.A. Hayek’s initial proposals for what became the Mont Pèlerin Society. Mises stresses that those who favor liberty and freedom and oppose totalitarianism must also oppose interventionism. The memo argues that those who fought and lost against the rising tide of totalitarianism at the turn of the 20th Century lost their battles because they settled for middle-of-the-road policies that conceded considerable ground to the socialists. The weak point in Professor Hayek’s plan is that it relies upon the cooperation of many men who are today’s middle-of-the-roaders. As interventionists, they may not be the hoped-for intellectual pioneers to inspire people to build a freer world.

    Camillo Negro, Professor in Neurology at the University of Torino, was a pioneer of scientific film. From 1906 to 1908, with the help of his assistant Giuseppe Roasenda and in collaboration with Roberto Omegna, one of the most experienced cinematographers in Italy, he filmed some of his patients for scientific and educational purposes. During the war years, he continued his scientific film project at the Military Hospital in Torino, filming shell-shocked soldiers. In autumn 2011, the Museo Nazionale del Cinema, in partnership with the Faculty of Neurosciences of the University of Torino, presented a new critical edition of the neuropathological films directed by Negro. The Museum's collection also includes 16 mm footage probably filmed in 1930 by Doctor Fedele Negro, Camillo's son. One of these films is devoted to celebrating the effects of the so-called "Bulgarian cure" on Parkinson's disease.

    2013-01-01

    SUMMARY Respiratory viruses (including adenovirus, influenza virus, respiratory syncytial virus, coronavirus, and rhinovirus) cause a broad spectrum of disease in humans, ranging from mild influenza-like symptoms to acute respiratory failure. While species D adenoviruses and subtype H7 influenza viruses are known to possess an ocular tropism, documented human ocular disease has been reported following infection with all principal respiratory viruses. In this review, we describe the anatomical proximity and cellular receptor distribution between ocular and respiratory tissues. All major respiratory viruses and their association with human ocular disease are discussed. Research utilizing in vitro and in vivo models to study the ability of respiratory viruses to use the eye as a portal of entry as well as a primary site of virus replication is highlighted. Identification of shared receptor-binding preferences, host responses, and laboratory modeling protocols among these viruses provides a needed bridge between clinical and laboratory studies of virus tropism.

    Full Text Available Purpose: To review current knowledge about ocular effects of sulfur mustard (SM and the associated histopathologic findings and clinical manifestationsMethods: Literature review of medical articles (human and animal studies was accomplished using PubMed, Scopus and ISI databases. A total of 274 relevant articles in English were retrieved and reviewed thoroughly.Results: Eyes are the most sensitive organs to local toxic effects of mustard gas. Ocular injuries are mediated through different toxic mechanisms including: biochemical damages, biomolecular and gene expression modification, induction of immunologic and inflammatory reactions, disturbing ultrastructural architecture of the cornea, and long-lasting corneal denervation. The resulting ocular injuries can roughly be categorized into acute or chronic complications. Most of the patients recover from acute injuries, but a minority of victims will suffer from chronic ocular complications. Mustard gas keratopathy (MGK is a devastating late complication of SM intoxication that proceeds from limbal stem cell deficiency (LSCD.Conclusion: SM induces several different damaging changes in case of ocular exposure; hence leading to a broad spectrum of ocular manifestations in terms of severity, timing and form. Unfortunately, no effective strategy has been introduced yet to inhibit or restore these damaging changes.

    Full Text Available PURPOSE: To establish current definition, classification and staging, and to develop diagnosis and treatment recommendations for ocular allergy, by using Delphi approach. METHODS: Ten Latin American experts on ocular allergy participated in a 4-round Delphi panel approach. Four surveys were constructed and answered by panelists. A two-thirds majority was defined as consensus. Definition, classification, staging and diagnosis and treatment recommendations were the main outcomes. RESULTS: "Ocular allergy" was proposed as the general term to describe ocular allergic diseases. Consensus regarding classification was not reached. Signs and symptoms were considered extremely important for the diagnosis. It was consensus that a staging system should be proposed based on the disease severity. Environmental control, avoidance of allergens and the use of artificial tears were recommended as first line treatment. The secondary treatment should include topical anti-histamines, mast cell stabilizers and multi actions drugs. Topical non-steroidal anti-inflammatory and vasoconstrictors were not recommended. Topical corticosteroids were recommended as third line of treatment for the most severe keratoconjunctivitis. Consensus was not reached regarding the use of systemic corticosteroids or immunosuppressant. Surgical approach and unconventional treatments were not recommended as routine. CONCLUSION: The task of creating guidelines for ocular allergies showed to be very complex. Many controversial topics remain unsolved. A larger consensus including experts from different groups around the world may be needed to further improve the current recommendations for several aspects of ocular allergy.

    Ocular Tracking Resistance in U.S. Today (TRUST) annually evaluates in vitro antimicrobial susceptibility of Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae to ciprofloxacin, gatifloxacin, levofloxacin, moxifloxacin, penicillin, azithromycin, tobramycin, trimethoprim, and polymyxin B in national samples of ocular isolates. Laboratory investigation. Prospectively collected ocular isolates (197 S. aureus, 49 S. pneumoniae, and 32 H. influenzae) from 35 institutions and archived ocular isolates (760 S. pneumoniae and 356 H. influenzae) from 34 institutions were tested by an independent, central laboratory. Mean minimum inhibitory concentrations that would inhibit growth of 90% of the tested isolates (MIC(90)) were interpreted as susceptible, intermediate, or resistant according to standardized breakpoints for systemic treatment. S. aureus isolates were classified as methicillin susceptible (MSSA) or methicillin resistant (MRSA). MSSA or MRSA susceptibility patterns were virtually identical for the fluoroquinolones, that is, MSSA susceptibility was 79.9% to 81.1% and MRSA susceptibility was 15.2%. Trimethoprim was the only agent tested with high activity against MRSA. All S. pneumoniae isolates were susceptible to gatifloxacin, levofloxacin, and moxifloxacin; 89.8% were susceptible to ciprofloxacin. H. influenzae isolates were 100% susceptible to all tested agents but trimethoprim. Ocular TRUST 1 data were consistent with the eight-year longitudinal sample of archived ocular isolates. The fluoroquinolones were consistently active in MSSA, S. pneumoniae, and H. influenzae. After more than a decade of intensive ciprofloxacin and levofloxacin use as systemic therapy, 100% of ocular S. pneumoniae isolates were susceptible to gatifloxacin, levofloxacin, and moxifloxacin; nonsusceptibility to ciprofloxacin was less than 15%. High-level in vitro MRSA resistance suggests the need to consider alternative therapy to fluoroquinolones when MRSA is a

    Ocular tumours at the Tata Memorial Hospital, Bombay, form about 0.14% of all the proved cancer cases. In case of unilateral retinoblastoma with the other eye being not non-seeing for any reason, enucleation is advised, as the diagnosis may sometimes be in doubt. If after enucleation, optic nerve and/or peribulbar tissues are found to be involved, post-operative irradiation is given to the whole orbit. In bilateral retinoblastoma the more affected eye is enucleated and an attempt is made to preserve vision in the other eye. A tumour dose of 3500 to 4000 rad in about 4 weeks is given with a cobalt beam using a direct anterior field. A cataract that may develop has to be taken care of. Lateral and/or medial fields are used with deep X-rays. In certain cases, an implant of cobalt-60 or gold-198 grain is done. For carcinoma of conjuctiva, small lesions or early lesions are excised and a beta radiation dose of 2000 rad weekly for about 4 to 5 weeks is given; larger lesions require enucleation or exenteration followed by irradiation with super-voltage radiation. Post-irradiation sarcomas may develop many years later. Irradiation is repeated for recurrences. (M.G.B.)

    To determine the effect of steroid treatment on visual outcome and ocular complications in patients with presumed ocular tuberculosis. Retrospective review of patients with presumptive ocular tuberculosis. The clinical diagnosis was made based on ocular findings, positive purified protein derivative (PPD) testing of more than 15 mm induration, exclusion of other causes of uveitis and positive ocular response to anti-tuberculous therapy (ATT) within 4 weeks. Group 1 included patients who had received oral prednisone or subtenon injection of triamcinolone acetonide prior to ATT. Group 2 included patients who did not receive corticosteroid therapy prior to administration of ATT.   Among 500 consecutive new cases of uveitis encountered in 1997-2007 there were 49 (10%) patients with presumed ocular tuberculosis. These comprised 28 (57%) male and 21 (43%) female patients with a mean age of 45 years (range 12-76 years). Four (20%) patients in group 1 had initial visual acuity of 20/40 or better, in comparison to eight (28%) patients in group 2. At 1-year follow-up, six (30%) patients in group 1 had a visual acuity of 20/40 or better compared with 20 (69%) patients in group 2 (p = 0.007). Of 20 eyes (26%) in group 1 that had visual acuity of < 20/50 at 1-year follow up, 14 (70%) eyes developed severe chorioretinal lesion (p = 0.019). Early administration of corticosteroids without anti-tuberculous therapy in presumed ocular tuberculosis may lead to poor visual outcome compared with patients who did not receive corticosteroids prior to presentation. Furthermore, the severity of chorioretinitis lesion in the group of patients given corticosteroid prior to ATT may account for the poor visual outcome. © 2009 The Authors.

  8. Purinergic Receptors in Ocular Inflammation

    Full Text Available Inflammation is a complex process that implies the interaction between cells and molecular mediators, which, when not properly “tuned,” can lead to disease. When inflammation affects the eye, it can produce severe disorders affecting the superficial and internal parts of the visual organ. The nucleoside adenosine and nucleotides including adenine mononucleotides like ADP and ATP and dinucleotides such as P1,P4-diadenosine tetraphosphate (Ap4A, and P1,P5-diadenosine pentaphosphate (Ap5A are present in different ocular locations and therefore they may contribute/modulate inflammatory processes. Adenosine receptors, in particular A2A adenosine receptors, present anti-inflammatory action in acute and chronic retinal inflammation. Regarding the A3 receptor, selective agonists like N6-(3-iodobenzyl-5′-N-methylcarboxamidoadenosine (CF101 have been used for the treatment of inflammatory ophthalmic diseases such as dry eye and uveoretinitis. Sideways, diverse stimuli (sensory stimulation, large intraocular pressure increases can produce a release of ATP from ocular sensory innervation or after injury to ocular tissues. Then, ATP will activate purinergic P2 receptors present in sensory nerve endings, the iris, the ciliary body, or other tissues surrounding the anterior chamber of the eye to produce uveitis/endophthalmitis. In summary, adenosine and nucleotides can activate receptors in ocular structures susceptible to suffer from inflammatory processes. This involvement suggests the possible use of purinergic agonists and antagonists as therapeutic targets for ocular inflammation.

Assim, o objetivo geral é apresentar as nuances gerais do Programa de Desenvolvimento Profissional para Professores com a finalidade de contextualizar uma estratégia inovadora de formação de professores da rede básica pública de educação a partir das ações formativas desenvolvidas na área de Química. O programa foi ofertado pelo governo brasileiro aos professores da educação básica por meio de um acordo de cooperação internacional entre Brasil e Portugal. As formações ocorreram na Universidade do Porto e na Universidade de Aveiro. Foram ofertadas 175 vagas para professores de todas as regiões do Brasil nas áreas de Língua Portuguesa, Pedagogia, Física, Matemática e Química. A área de Química foi a única que ocorreu em ambas as instituições parceiras, sendo acompanhadas in loco. Percebe-se que o conhecimento por parte da comunidade de professores e pesquisadores sobre a ocorrência dessa formação ofertada pelo governo brasileiro é praticamente inexistente, assim faz-se se suma importância a divulgação dos contextos de ocorrência da mesma, tendo enquanto macro destaque a valorização dos professores da rede pública nacional.

    Full Text Available Rho kinases (ROCKs have a crucial role in actin-cytoskeletal reorganization and thus are involved in broad aspects of cell motility, from smooth muscle contraction to neurite outgrowth. The first marketed ROCK inhibitor, called fasudil, has been used safely for treatment of cerebral vasospasm since 1995 in Japan. During the succeeding decades ROCK inhibitors have been applied in many pathological conditions from central nervous system disorders to cardiovascular disease as potential therapeutic agents or experimental tools to help understand the underlying (pathomechanisms. In 2014, a fasudil derivate named ripasudil was accepted for clinical use in glaucoma and ocular hypertension. Since ROCK kinases are widely expressed in ocular tissues, they have been implicated in the pathology of many ocular conditions such as corneal dysfunction, glaucoma, cataract, diabetic retinopathy, age-related macular degeneration, and retinal detachment. This paper aims to provide an overview of the most recent status/application of ROCK inhibitors in the field of eye disease.

    Full Text Available Ocular chemical burns are common and serious ocular emergencies that require immediate and intensive evaluation and care. The victims of such incidents are usually young, and therefore loss of vision and disfigurement could dramatically affect their lives. The clinical course can be divided into immediate, acute, early, and late reparative phases. The degree of limbal, corneal, and conjunctival involvement at the time of injury is critically associated with prognosis. The treatment starts with simple but vision saving steps and is continued with complicated surgical procedures later in the course of the disease. The goal of treatment is to restore the normal ocular surface anatomy and function. Limbal stem cell transplantation, amniotic membrane transplantation, and ultimately keratoprosthesis may be indicated depending on the patients’ needs.

    To evaluate associations between sensations of ocular itch and dry eye (DE) symptoms, including ocular pain, and DE signs. A cross-sectional study of 324 patients seen in the Miami Veterans Affairs eye clinic was performed. The evaluation consisted of questionnaires regarding ocular itch, DE symptoms, descriptors of neuropathic-like ocular pain (NOP), and evoked pain sensitivity testing on the forehead and forearm, followed by a comprehensive ocular surface examination including corneal mechanical sensitivity testing. Analyses were performed to examine for differences between those with and without subjective complaints of ocular itch. The mean age was 62 years with 92% being male. Symptoms of DE and NOP were more frequent in patients with moderate-severe ocular itch compared to those with no or mild ocular itch symptoms. With the exception of ocular surface inflammation (abnormal matrix metalloproteinase 9 testing) which was less common in those with moderate-severe ocular itch symptoms, DE signs were not related to ocular itch. Individuals with moderate-severe ocular itch also demonstrated greater sensitivity to evoked pain on the forearm and had higher non-ocular pain, depression, and post-traumatic stress disorders scores, compared to those with no or mild itch symptoms. Subjects with moderate-severe ocular itch symptoms have more severe symptoms of DE, NOP, non-ocular pain and demonstrate abnormal somatosensory testing in the form of increased sensitivity to evoked pain at a site remote from the eye, consistent with generalized hypersensitivity.

    Ocular conditions such as trauma, painful red eye of any cause, painless sudden visual loss and others are commonly seen as ocular emergencies, and can lead to ocular morbidity and visual loss. To determine types and causes of ocular emergencies seen at Menelik II hospital. A cross-sectional study was conducted from April to October, 2007. Consecutive patients who presented with ocular emergencies at any time of the day were prospectively evaluated and registered on a formatted questionnaire. Evaluation of the patients included history of presenting illness, visual acuity testing intraocular pressure measurement on non-perforated and non-infected eyes, and complete eye examination in order to arrive at the diagnosis. A total of 26,400 patients attended Menelik II hospital during the study period. Of these, 758 (3%) were persons with an ocular emergency. The majority of patients (n=551; 72.7%) were male, with a male to female ratio of 2.7:1. The age group of 16 to 30 years was the most affected (47.9%), followed by those aged 15 years or younger (27.3%). Ocular trauma and ocular infections accounted for 75.6% and 13.1% of cases, respectively. Of the total ocular emergencies, open globe injuries constituted 171 (22.6%), corneal foreign bodies and abrasion 125 (16.5%), and open adnexal injuries 119 (15.7%). Metal and wood were the commonest work-related causes of ocular injuries in adults, with both together accounting for 60% of all ocular injuries. Children, on the other hand, sustained ocular injury while playing with others in 128 (22.3%) of cases. This study was able to provide a more complete picture to improve understanding of the nature and circumstances of ocular emergencies in Ethiopia. Ocular emergencies were dominated by ocular trauma, particularly affecting males and working-age adults. Public education and use of protective safety measures are recommended to alleviate the problem.

    In cooperation with the New York State Athletic Commission, 74 boxers applying for a new or yearly renewal license were sequentially referred over a 2-year period for a complete dilated ocular examination at the Sports Vision Institute of the Manhattan Eye, Ear and Throat Hospital. At least one ocular injury was found in 66% of boxers. Vision-threatening injuries, defined as significant damage to the angle, lens, macula, or peripheral retina occurred in 58% of boxers. Nineteen percent of boxers had angle abnormalities. Nineteen percent of boxers had pathologic cataracts, over 70% of these were posterior subcapsular. Six boxers had macular lesions. A total of 24% of boxers had retinal tears. Standardized photographs were used to distinguish pathologic cataracts from congenital opacities and pathologic retinal tears from atrophic holes. Attempts were made to identify risk factors in boxing that might be predictive for ocular injury. Variables included age, weight division, left- or right-handedness, total number of losses, and total number of bouts. Significant correlations were found between the total number of bouts and the total number of losses, and the presence of retinal tears. College varsity athletes were selected as controls. Significant differences were found between boxers and controls for the total number of injuries, total vision-threatening injuries, and the number of retinal tears. A series of recommendations are proposed to aide in the early detection and prevention of serious ocular injuries.

    This report evaluates the clinical characteristics of surfing-related ocular trauma to learn the nature of such injuries and propose possible preventive measures. The authors reviewed 11 cases of surfing-related eye injuries caused by direct trauma from the surfboard, studying their mechanism of injury, the associated ocular complications, and the anatomic and visual outcomes of surgical repair. Surfing-related ocular injuries occurred exclusively in young males (mean age, 24.8 years; range, 14-37 years). The mechanism of injury most frequently responsible was impact with the sharp nose of the surfboard following a fall. Serious posterior segment complications were observed in all 11 patients, with nine patients suffering ruptured globes. Despite immediate medical attention, five patients did not recover ambulatory levels of visual acuity (>5/200). Surfing-related ocular trauma presenting to the retinal specialist typically leaves the patient with a permanent visual disability. Important factors contributing to these high-velocity injuries include the sharply pointed nose of the surfboard and the leash keeping the surfer in close proximity to the board following a fall. A simple modification in surfboard design such as blunting the sharp nose of the surfboard, or appropriate protective guards fitted over the surfboard nose, should lessen the severity of such injuries.

    To evaluate the outcome of treatment with methotrexate for noninfectious ocular inflammation. Retrospective cohort study. Patients with noninfectious ocular inflammation managed at 4 tertiary ocular inflammation clinics in the United States observed to add methotrexate as a single, noncorticosteroid immunosuppressive agent to their treatment regimen, between 1979 and 2007, inclusive. Participants were identified from the Systemic Immunosuppressive Therapy for Eye Diseases Cohort Study. Demographic and clinical characteristics, including dosage, route of administration of methotrexate, and main outcome measures, were obtained for every eye of every patient at every visit via medical record review by trained expert reviewers. Control of inflammation, corticosteroid-sparing effects, and incidence of and reason for discontinuation of therapy. Among 384 patients (639 eyes) observed from the point of addition of methotrexate to an anti-inflammatory regimen, 32.8%, 9.9%, 21.4%, 14.6%, 15.1%, and 6.3%, respectively, had anterior uveitis, intermediate uveitis, posterior or panuveitis, scleritis, ocular mucous membrane pemphigoid, and other forms of ocular inflammation. In these groups, complete suppression of inflammation sustained for >or=28 days was achieved within 6 months in 55.6%, 47.4%, 38.6%, 56.4%, 39.5%, and 76.7%, respectively. Corticosteroid-sparing success (sustained suppression of inflammation with prednisone Methotrexate was discontinued within 1 year by 42% of patients. It was discontinued owing to ineffectiveness in 50 patients (13%); 60 patients (16%) discontinued because of side effects, which typically were reversible with dose reduction or discontinuation. Remission was seen in 43 patients, with 7.7% remitting within 1 year of treatment. Our data suggest that adding methotrexate to an anti-inflammatory regimen not involving other noncorticosteroid immunosuppressive drugs is moderately effective for management of inflammatory activity and for achieving

    Full Text Available BACKGROUND This prospective study aimed to evaluate the incidence of ocular manifestations in head injury and their correlation with the intracranial lesions. MATERIALS AND METHODS A total of 108 consecutive cases of closed head injury admitted in the neurosurgical ward of a tertiary teaching hospital underwent a thorough ophthalmic assessment. Clinical examination, radiological imaging and Glasgow Coma Scale (GCS were applied to grade the severity of injury. RESULTS Total number of 108 patients of head injury were examined of which 38 patients had ocular manifestations (35.18%. Of these, 85.18% were males, 84% of injuries were due to road traffic accidents and 16% were due to fall from a height. The ocular manifestations were as follows- Orbital complications were seen in 6 patients (15.8%. Anterior segment manifestations included black eyes seen in 10 patients (26.3%, subconjunctival haemorrhage in 10.5% of patients (4 patients, corneal involvement in 21% of patients (8 patients and pupillary involvement in 50% of patients (19 patients. Posterior segment manifestations were seen in 26.3% of patients (10 patients and were as follows- Purtscher’s retinopathy in 2 patients and optic atrophy in 5 patients. Cranial nerve palsies were seen in 15 patients (39.47% and supranuclear movement disorders were seen in 3 patients (8%. CONCLUSION Even though, neurosurgeons perform comprehensive clinical examination including eye examination, the main purpose is limited to aid topical diagnosis of neurological lesions. This study emphasises the importance of a detailed eye examination by an ophthalmologist to prevent irreversible visual loss in addition to aiding in the neurological diagnosis. Pupillary involvement, papilloedema and ocular motor paresis pointed to a more severe head injury. This observational prospective study helped us to correlate the severity of head injuries in association with ocular findings in patients admitted in neurosurgical ward

    Full Text Available ABSTRACT The aim of this study was to identify the prevalence of satisfaction among accounting professors in Brazil throughout their careers. The research is classified as descriptive and used a quantitative approach to data analysis. 641 valid responses were obtained from professors from all regions of Brazil. The results show that a feeling of satisfaction prevails among accounting course professors, as most of them “like the profession” and, in general, "are satisfied with it”. It was found that levels of satisfaction are higher among individuals with more experience, in that in their first years in the job (one to three years, professors have lower satisfaction rates; the highest levels of satisfaction are found in the final stage (over 35 years. The main factor that influences satisfaction is personal fulfillment (teaching work and relationship with students. It was also possible to identify that positive feelings about teaching predominate (67.3% compared to negative ones (32.7%. These results show the need for greater attention to be paid in the early years of the career in order to avoid a "reality clash". They also show the need for other studies to investigate how the phases in the life cycle of accounting professors are characterized.

    As the title of my paper indicates, Dr. Rudolph Binion was my professor, mentor, and a leading psychohistorian. My paper in memoriam to Rudolph Binion is intended as both a retrospective and an introspective account of my relationship with him, as he had a pivotal influence on me when he was my professor at Columbia University. His help and influence continued after I left graduate school. In my paper I also deal with the enormous stresses of navigating through graduate school, for those students whose goal was to earn the Ph.D. degree. Some examinations were dreaded, For Example The "Examination in Subjects," popularly called the "Oral Exam." The "incubation" period was long indeed, frequently averaging nearly ten years, and it was an ordeal, as the rate of attrition was very high. There is then also the question of "ego strength" and that of "transference" toward the professor. Graduate school is indeed a long and strenuous challenge. I took a seminar in modern French history, a requirement for the Master's degree with Professor Binion, which was consequential for me, as he taught me to be objective in writing history. Professor Binion was a demanding and outstanding teacher.

    He is a brilliant math Professor with a peculiar problem—ever since a traumatic head injury, he has lived with only eighty minutes of short-term memory. She is an astute young Housekeeper—with a ten-year-old son—who is hired to care for the Professor. And every morning, as the Professor and the Housekeeper are introduced to each other anew, a strange and beautiful relationship blossoms between them. Though he cannot hold memories for long (his brain is like a tape that begins to erase itself every eighty minutes), the Professor's mind is still alive with elegant equations from the past. And the numbers, in all of their articulate order, reveal a sheltering and poetic world to both the Housekeeper and her young son. The Professor is capable of discovering connections between the simplest of quantities—like the Housekeeper's shoe size—and the universe at large, drawing their lives ever closer and more profoundly together, even as his memory slips away.

    This Alternative Gallery feature introduces the photographic artist Professor Richard Sawdon Smith. Professor Sawdon Smith's work stems around a fascination with representations of anatomy that have been fuelled by his experience as a hospital patient. The work has allowed him to explore ideas through the use of medical illustrations which include early anatomical drawings, personal medical photography and facial modelling. The work highlights how such imagery can be used in the context of a patient seeking understanding and acceptance of ill health and disease using the body as a canvas on which to translate the experience.

    Full Text Available We report the case of a 52-year-old woman with advanced colorectal cancer who was treated with oxaliplatin on a FOLFOX schedule. After 3 cycles of chemotherapy, she started to complain of visual loss, altered color vision and neurological symptoms. Due to the suspicion of ocular and neurological toxicity, antineoplastic treatment was stopped. Her visual field showed a concentric bilateral scotoma and the electrooculogram test revealed severe impairment of the retinal pigment epithelium. Visual acuity, color vision and visual field recovered completely 8 months later, although electrooculogram remained abnormal. Ocular toxicity has been reported as an infrequent adverse event of oxaliplatin. Findings in this case indicate toxicity of this chemotherapeutic agent on the retinal pigment epithelium, which has not been reported before. This damage could be permanent, and it thus differs from previously described oxaliplatin-induced ocular toxicities, which are usually transient and reversible. With increasing use of oxaliplatin as first-line treatment in advanced colorectal cancer, we have to be aware of this possible toxicity.

    Full Text Available Este estudo focaliza as representações sociais de professores do ensino fundamental acerca da violência intrafamiliar. A amostra foi de 94 professores de escolas públicas e privadas (Distrito Federal e Goiás, graduandos em Pedagogia. Na coleta de dados, aplicou-se um questionário visando apreender as representações sobre violência intrafamiliar, nas dimensões informação, campo das representações sociais e atitudes dos sujeitos diante de casos comprovados ou suspeitos de alunos vitimados pela violência intrafamiliar. Os resultados apontam contradições e ambivalências entre os sentimentos e as atitudes dos professores em relação ao fenômeno. Indicam, ainda, que a representação social da violência intrafamiliar, para grande parte dos sujeitos, ainda passa pela consideração do poder da autoridade paterna/familiar, que dá direito aos pais de educar seus filhos como melhor lhes convier, indicando a necessidade da capacitação de professores, no âmbito da formação inicial e continuada, para lidar adequadamente com a problemática da violência intrafamiliar, no cotidiano escolar.

Com o objetivo de investigar as estratégias usadas por um professor bem avaliado pelos estudantes, registramos, em vídeo, um conjunto de aulas e fizemos a análise das mesmas. Esta análise permitiu um entendimento inicial de como o professor organiza o seu próprio trabalho, como navega entre diferentes tipos de discursos e como dá suporte ao processo de significação. Ao mesmo tempo, a análise revelou como as interações são produzidas no espaço/tempo da sala de aula, e como as diferentes estratégias usadas auxiliam no engajamento dos estudantes. Por meio de entrevista semiestruturada, buscamos, no professor, indícios que nos permitissem entender como este construiu as estratégias usadas nas aulas. Observamos a presença de um processo reflexivo sobre as experiências vividas e identificamos algumas pistas que nos permitiram argumentar sobre a construção dessas estratégias.

A presente revisão sistemática da literatura analisou produções científicas nacionais publicadas entre 2010 e 2015, com vista a identificar principais sintomas e/ou adoecimentos psíquicos entre professores brasileiros. Recorreu-se às bases LILACS, SciELO, Index Psicologia, Educ@ e PePSIC. Os critérios de elegibilidade e análise seguiram as diretrizes do PRISMA. Dos 97 artigos encontrados, 15 foram analisados, os quais indicaram interesse multidisciplinar pela temática, predominância de estudos descritivos e correlacionais e recorrência de investigações em escolas públicas e de Ensino Fundamental. O principal adoecimento mental investigado é a síndrome de burnout e os sintomas prevalentes foram o estresse e a ansiedade. Espera-se que esses resultados direcionem novas pesquisas e estimulem o planejamento de intervenções eficazes voltadas para a saúde mental de professores.

    Full Text Available OBJETIVO: Comparar dois métodos de aplicação de toxina botulínica A (TBA em músculo ocular externo: com auxílio de eletromiógrafo (EMG e com a pinça de Mendonça. MÉTODOS: Foram analisados no Departamento de Oftalmologia da UNIFESP 29 pacientes que apresentavam estrabismo e baixa acuidade visual em um olho. Foram divididos em dois grupos: grupo I - 17 pacientes que receberam a toxina botulínica A por meio de injeção com auxílio da pinça de Mendonça e grupo II - 12 pacientes que receberam a toxina botulínica A por injeção guiada pelo eletromiógrafo. Os pacientes dos dois grupos foram avaliados no 7º e no 14º dia após aplicação. Compararam-se os resultados dos dois grupos neste período de tempo. Os testes de correlação de Friedman e Mann-Whitney foram usados para análise estatística. RESULTADOS: Houve diferença estatística entre as médias de desvio pré-aplicação e em pelo menos um período (7º ou 14º dia após aplicação, tanto no grupo dos pacientes em que foi utilizada a pinça, quanto no grupo de pacientes em que foi utilizado o eletromiógrafo. Não houve diferença estatística dos desvios pré-aplicação e pós-aplicação entre os dois grupos. CONCLUSÃO: Os dois métodos de aplicação da toxina botulínica A são equivalentes e portanto, o uso da pinça de Mendonça pode ser método alternativo ao uso do eletromiógrafo, para guiar a injeção de toxina botulínica A.PURPOSE: To compare two methods of botulinum toxin A (BTA injection into the extraocular muscle (EOM: the electromyographically (EMG guided injection and the injection using Mendonça's forceps.

  20. Raman Spectroscopy of Ocular Tissue

    Ermakov, Igor V.; Sharifzadeh, Mohsen; Gellermann, Warner

    The optically transparent nature of the human eye has motivated numerous Raman studies aimed at the non-invasive optical probing of ocular tissue components critical to healthy vision. Investigations include the qualitative and quantitative detection of tissue-specific molecular constituents, compositional changes occurring with development of ocular pathology, and the detection and tracking of ocular drugs and nutritional supplements. Motivated by a better understanding of the molecular mechanisms leading to cataract formation in the aging human lens, a great deal of work has centered on the Raman detection of proteins and water content in the lens. Several protein groups and the hydroxyl response are readily detectable. Changes of protein compositions can be studied in excised noncataractous tissue versus aged tissue preparations as well as in tissue samples with artificially induced cataracts. Most of these studies are carried out in vitro using suitable animal models and conventional Raman techniques. Tissue water content plays an important role in optimum light transmission of the outermost transparent ocular structure, the cornea. Using confocal Raman spectroscopy techniques, it has been possible to non-invasively measure the water to protein ratio as a measure of hydration status and to track drug-induced changes of the hydration levels in the rabbit cornea at various depths. The aqueous humor, normally supplying nutrients to cornea and lens, has an advantageous anterior location for Raman studies. Increasing efforts are pursued to non-invasively detect the presence of glucose and therapeutic concentrations of antibiotic drugs in this medium. In retinal tissue, Raman spectroscopy proves to be an important tool for research into the causes of macular degeneration, the leading cause of irreversible vision disorders and blindness in the elderly. It has been possible to detect the spectral features of advanced glycation and advanced lipooxydation end products in

A abordagem fenomenológico-hermenêutica foi utilizada a fim de retomar os principais temas desta experiência. Seis ex-gestores universitários emprestaram suas experiências vivenciadas em universidades pertencentes à Associação Catarinense das Fundações Educacionais, através das entrevistas em três tempos, realizadas entre maio de 2009 e março de 2010. Somente fazendo parte da gestão universitária os professores perceberam a complexidade dessa prática. O relacionamento interpessoal foi um fator importante na prática gerencial desses professores, fato este corroborado pela literatura (MINTZBERG, 1990. Recorrendo às entrevistas transcritas, foi possível resgatar três grandes temas centrais: as relações profissionais, o relacionamento com os alunos e as relações familiares. Nas relações profissionais estabelecidas, eles perceberam a necessidade do gerenciamento do trabalho em equipe. O relacionamento frequente com os alunos fez parte do dia a dia do gestor universitário, configurando-se como um dos seus grandes desafios. A família esteve ao lado dos professores, apoiando-os e cobrando deles mais tempo de convívio familiar. Palavras-chave: Relações interpessoais. Professor universitário. Líder. Transição.

    High altitude, often characterized by settings over 2400m, can be detrimental to the human body and pose a significant risk to ocular health. Reports concerning various ocular morbidities occurring as a consequence of high altitude are limited in the current literature. This study was aimed at evaluating the ocular health of porters working at high altitudesof Himalayas in Nepal. A mobile eye clinic was set up in Ghat and patient data were collected from its out- patient unit by a team of seven optometrists which was run for five days. Ghat is a small village in north-eastern Nepal, located at 2860 m altitude. Travellers walking through the trekking route were invited to get their eyes checked at the clinic. Comprehensive ocular examinations were performed, including visual acuities, objective and subjective refraction, anterior and posterior segment evaluations, and intraocular pressure measurements; blood pressure and blood glucose levels were also measured as required. Ocular therapeutics, prescription glasses, sunglasses and ocular health referrals were provided free of cost as necessary. A total of 1890 people visited the eye clinic, among which 57.4% (n=1084) were porters. Almost half of the porters had an ocular morbidity. Correctable refractive error was most prevalent, with other ocular health-related complications, including dry eye disease, infectious disorders, glaucoma and cataract. Proper provision of regular and effective eye care services should be made more available for those residing at these high altitudes in Nepal. © NEPjOPH.

    2017-01-01

    ABSTRACT Objective: to analyze the work process of nursing professors. Method: descriptive, exploratory and qualitative study, developed with a focus on critical epidemiology, carried out at a School of Nursing in Chile. The research subjects consist of 17 nursing professors, with whom individual semi-structured interviews were carried out and nine participated in a focus group. The Ethics Committee approved this study. Results: 88.2% were female, mean age of 42 years, 47% were married, 94% were Chilean, average length of service in the institution of 2.8 years, and 23.5% had a master’s degree. Regarding the work process, the students were the work object, the tools used were the knowledge and the experience as a nurse, and the work environment was considered good. Regarding the form of work organization, 76% have a 44-hour workweek, the wage was considered inadequate and the workload was higher than foreseen in the contract. The dialectic of the nursing work process is evidenced, demonstrating the contradiction between the low wages and labor overload and the narratives reporting a good work environment, personal fulfillment and transcendence that goes far beyond work. Conclusions: the work process allows describing the work components of the nursing professors, which are consistent with the results of the literature and show the dialectic of the nursing work process.

    2016-06-01

    This paper presents a complete overview of the scientific, professional and social activity of a great Polish pathologist, Witold Nowicki (1878-1941), from mainly Polish-written, original sources with a major impact on mostly his own publications. The biographical commemoration of this eminent professor is not only due to the fact that he provided a profound microscopic characterization of pneumatosis cystoides in 1909 and 1924. Nowicki greatly influenced the development of anatomical pathology in Poland, having authored over 82 publications, with special reference to tuberculosis, lung cancer, sarcomatous carcinomas, scleroma and others. However, the first of all his merits for the readership of Polish pathologists was his textbook titled Anatomical Pathology, which was a basic pathology manual in pre-war Poland. Witold Nowicki - as the head of the academic pathological anatomy department and former dean of the medical faculty - was shot with other professors by Nazi Germans in the Wuleckie hills in Lvov during World War Two. Professor Nowicki was described as being "small in size but great in spirit" by one of his associates, and remains an outstanding example of a meticulous pathologist, a patient tutor and a great social activist to follow.

    The ocular motor nerves (OMNs) comprise the oculomotor, trochlear and the abducens nerves. According to their course, they are divided into four or five anatomic segments: intra-axial, cisternal, cavernous and intra-orbital and, for the abducens nerve, an additional interdural segment. Magnetic resonance imaging is the imaging method of choice in the evaluation of the normal and pathologic ocular motor nerves. CT still plays a limited but important role in the evaluation of the intraosseous portions at the skull base and bony foramina. We describe for each segment of these cranial nerves, the normal anatomy, the most appropriate image sequences and planes, their imaging appearance and pathologic conditions. Magnetic resonance imaging with high magnetic fields is a developing and promising technique. We describe our initial experience with a Phillips 7.0 T MRI scanner in the evaluation of the brainstem segments of the OMNs. As imaging becomes more refined, an understanding of the detailed anatomy is increasingly necessary, as the demand on radiology to diagnose smaller lesions also increases.

    Full Text Available The ocular surface is exceptionally rich in complexity and functionality. Severe ocular surface disorders/conditions, such as chemical or thermal injuries, Stevens-Johnson syndrome (SJS, ocular cicatricial pemphigoid, neurotrophic keratopathy, chronic limbitis, and severe microbial keratitis cause significant morbidities and even corneal blindness. Hypofunction may be caused by Aniridia, Neurotrophy, Endocrine, Pterygium and Chronic limbitis Approximately 6000 patients are seen in Ocular Surface Clinic every year; almost 80% have some form of dry eyes. About 125 new patients of Stevens Johnson Syndrome are seen in a year of which approximately 25% may benefit from Cultured Epithelial Transplant and 75 new patients of thermal/chemical injury in a year of which almost 80% will benefit from Stem Cell Transplantation. Of the 128 severe vernal keratoconjunctivitis which were seen in the ocular surface clinic, 10% require stem cell transplantation. Nearly 30 new cases of Ocular cicatrical pemphigoid every year are seen and they may need stem cell transplantation. In addition, several patients with persistent epithelial defects may benefit from limbal stem cell transplantation to alleviate, maintain conjunctivalization regression and corneal avascularity limbal deficiency, and restore vision. Even if granted that this statistics is for a single large ophthalmic hospital, for a large country as India with 1.1 billion populations, the number of patients requiring corneal stem cell transplantation is enormous. Stem cells in the palisades of Vogt participate in regeneration and preservation of corneal transparency and avascularity. The diminished regenerative capacity seen in LSCD is characterized by persistent epithelial defects, erosion and ulceration, conjunctivalization and neovascularization, and chronic inflammation. Standard corneal transplantation for restoration of corneal clarity and avascularity is a contraindication in the surgical management

A pesquisa, realizada por meio de questionários, teve como participantes 18 professores de uma diretoria de ensino do interior do estado de São Paulo, divididos entre: 8 professores da sala regular que ministraram aula no ensino fundamental para alunos com deficiência intelectual, 8 professores que ministraram aula no ensino médio para alunos com deficiência intelectual e 2 professores da educação especial. Os resultados indicaram que os professores reconhecem a importância da adaptação curricular no ensino dos alunos com deficiência intelectual, mas não tem clareza da definição do conceito e da utilização de recursos e estratégias adaptadas para favorecer a aprendizagem dos conteúdos propostos no currículo. Todavia, os dados revelaram a necessidade de as professoras compartilharem de uma visão mais ampla do como fazer adaptação dos conteúdos escolares. Tais dados indicaram a necessidade de programas direcionados à formação dos professores para atuarem na elaboração de adaptação curricular junto aos alunos com deficiência intelectual.

    Hypohidrotic ectodermal dysplasia (HED) is a group of rare multisystemic genetic syndromes that affects ectodermal structures such as skin, hair, nails, teeth and sweat glands. The authors present a case of a child with ocular and dermatological signs of HED along with severe involvement of other multiple organ systems. The family history could be traced to four generations and there was an observed trend of increase in severity of signs and symptoms occurring at younger age. The purpose of this case report is to create awareness in ophthalmic community of its diagnosis and clinical manifestations. This case highlights the role of multidisciplinary approach for management of systemic disease, genetic evaluation of affected individuals and carriers and genetic counselling. PMID:22700604

    The eye is an easily accessible, highly compartmentalised and immune-privileged organ that offers unique advantages as a gene therapy target. Significant advancements have been made in understanding the genetic pathogenesis of ocular diseases, and gene replacement and gene silencing have been implicated as potentially efficacious therapies. Recent improvements have been made in the safety and specificity of vector-based ocular gene transfer methods. Proof-of-concept for vector-based gene therapies has also been established in several experimental models of human ocular diseases. After nearly two decades of ocular gene therapy research, preliminary successes are now being reported in phase 1 clinical trials for the treatment of Leber congenital amaurosis. This review describes current developments and future prospects for ocular gene therapy. Novel methods are being developed to enhance the performance and regulation of recombinant adeno-associated virus- and lentivirus-mediated ocular gene transfer. Gene therapy prospects have advanced for a variety of retinal disorders, including retinitis pigmentosa, retinoschisis, Stargardt disease and age-related macular degeneration. Advances have also been made using experimental models for non-retinal diseases, such as uveitis and glaucoma. These methodological advancements are critical for the implementation of additional gene-based therapies for human ocular diseases in the near future.

    2008-11-01

    To review the recent literature regarding combat ocular trauma during hostilities in Operations Iraqi Freedom and Enduring Freedom, describe the classification of combat ocular trauma, and offer strategies that may assist in the management of eye injuries. Several recent publications have highlighted features of combat ocular trauma from Operation Iraqi Freedom. The most common cause of today's combat ocular injuries is unconventional fragmentary munitions causing significant blast injuries. These explosive munitions cause high rates of concomitant nonocular injuries such as traumatic brain injury, amputation, and other organ injuries. The most frequent ocular injuries include open-globe and adnexal lacerations. The extreme severity of combat-related open-globe injuries leads to high rates of primary enucleation and retained intraocular foreign bodies. Visual outcomes of intraocular foreign body injuries are similar to other series despite delayed removal, and no cases of endophthalmitis have occurred. Despite these advances, however, significant vision loss persists in cases of perforating globe injuries as well as open and closed-globe trauma involving the posterior segment. This review summarizes the recent literature describing ocular and systemic injuries sustained during Operations Iraqi and Enduring Freedom. An emphasis on classification of ocular injuries as well as a discussion of main outcome measures and complications is discussed.

  5. The role of herpesviruses in ocular infections

    Full Text Available Asim V Farooq1, Arpeet Shah1, Deepak Shukla21Department of Ophthalmology and Visual Sciences, 2Department of Microbiology and Immunology, College of Medicine, University of Illinois at Chicago, Chicago, IL, USAAbstract: Ocular infections caused by herpesviruses are an important cause of morbidity. The majority of cases are believed to be associated with herpes simplex virus type-1 (HSV-1, although HSV-2, varicella zoster virus (VZV, cytomegalovirus (CMV and Epstein–Barr virus (EBV are also associated with various ocular diseases. The ability of some herpes viruses to infect various anatomic regions of the eye may be facilitated by entry processes that are cell-type specific, and in many cases may occur more frequently in the immunocompromised. The elimination of the role of herpesviruses in ocular disease remains elusive, as they often develop life-long latency in a large proportion of humans. Experimental vaccines for ocular HSV have shown some benefit in animal models, a result that has not been adequately demonstrated in clinical trials. Meanwhile, ocular involvement in VZV remains unpredictable, and CMV retinitis continues to be an important cause of blindness in those infected by HIV.Keywords: ocular herpes, viral entry, antivirals, epidemiology, seroprevalence, ocular lymphomas, viral vaccine

    2010-11-01

    The aim of this study was to estimate the frequency and severity of ocular involvement in paediatric patients with haemolytic uraemic syndrome (HUS). The study was designed as an institutional, retrospective, observational case series. Charts for all 87 paediatric patients with HUS treated at the University Children's Hospital Zurich between 1995 and 2007 were reviewed. Patients with ocular involvement were identified and clinical findings presented. Three of 69 examined patients with HUS showed ocular involvement. Ophthalmic findings in two children were consistent with bilateral Purtscher retinopathy, showing multiple haemorrhages, exudations and superficial retinal whitening. The third child presented with bilateral isolated central intraretinal haemorrhages as a milder form of ocular involvement. In one of the children with Purtscher retinopathy, laser photocoagulation was required for bilateral rubeosis irides and development of disc neovascularization. Longterm outcomes in the two severely affected children showed decreased visual acuity caused by partial atrophy of the optic nerves. In the milder case visual acuity was not impaired at any time. A minority of paediatric patients with HUS developed ocular involvement. Acute ocular findings varied in severity from isolated intraretinal haemorrhages to Purtscher-like retinopathy with retinal ischaemia. Longterm complications included the development of neovascularizations and consecutive optic nerve atrophy. Although ocular involvement in HUS seems to be rare, physicians should be aware of this complication because of its possible vision-endangering consequences. © 2009 The Authors.

    Full Text Available Thelaziasis is an Arthropod-born disease of the eye and adnexa caused by Thelazia callipaeda, a nematode parasite transmitted by drosophilid flies to carnivores and humans. Because of its distribution mainly confined to South Asian countries and Russia, it is commonly known as Oriental Eye worm. It is often under-reported and not been given its due clinical importance. We report first case of human Thelaziasis from Hassan District, Karnataka. Five creamy-white, translucent worms were removed from the conjunctival sac of a 74-year-old male patient. Based on morphological characters, the worms were identified as nematodes belonging to the genus Thelazia and speciation was confirmed by CDC, Atlanta as callipaeda. Rarity of the disease and its ability to cause both extra and intraocular manifestations leading to ocular morbidity is the reason for presenting this case. From the available data, this is the first case report from Karnataka, India.

    2004-03-01

    Tear clearance/turnover provides a global assessment of the function of the lacrimal functional unit and of tear exchange on the ocular surface. It is an indirect measure of dry eye induced inflammation on the ocular surface. It shows better correlation with the severity of ocular irritation symptoms and corneal epithelial disease in dry eye than the Schirmer 1 test. Delayed tear clearance may prove to be the best measure for identifying patients with tear film disorders who may respond to anti-inflammatory therapy.

    We present a case of ocular syphilis after a renal transplantation involving progressive vision loss without clinically identifiable ocular disease. Electroretinography showed signs of ischemia, especially in the internal retina. A serological test was positive for syphilis. Lumbar puncture revealed lymphocytic meningitis and a positive serologic test for syphilis in the cerebrospinal fluid. The patient was treated with penicillin, and had a quick vision improvement. In the case of transplant recipients, clinicians should always consider the diagnosis of ocular syphilis in cases with unexplained visual acuity decrement, as this condition may cause serious complications if not treated.

    Full Text Available Este estudo busca identificar o perfil educacional dos professores do ensino fundamental das séries iniciais. Seu objetivo é fornecer situações reflexivas onde os professores possam discutir sobre sua própria formação. Os dados foram obtidos a partir das respostas de onze professores de escola pública à um questionário. Também foram realizados encontros quinzenais com esses professores que formaram um Grupo de Trabalho, onde estes encontros foram filmados, transcritos e analisados. Durante a pesquisa verificou-se haver problemas pedagógicos no processo de ensino aprendizagem, no método de ensino adotado, no estabelecimento e valorização da relação professor-aluno e na interação entre os alunos quando da construção do conhecimento científico. No final do estudo, entendeu-se que os profissionais pesquisados apresentam falhas em sua formação como professores; não participam de cursos de atualização; e quando enfrentam dificuldades de entendimento em como lidar com algum conteúdo científico com os alunos, os professores pesquisam em livros escolares para sanar suas dúvidas. Os professores também apontaram que os cursos de atualização promovidos pela Diretoria de Ensino são considerados muito teóricos e pouco práticos, e não apresentam nenhuma ligação com o contexto em que os professores estão inseridos.

    Full Text Available Neste estudo partimos da consideração da relevância da autonomia do professor na organização das relações de ensino de que participa em sala de aula. Como prescrições dirigidas ao professor se opõem à possibilidade de autonomia, buscamos compreender manifestações de caráter prescritivo visando contribuir para a diminuição de sua ocorrência. Para tanto, nos apoiamos numa vertente da análise do discurso para compreender como, em certas condições de produção, prescrições, explicitas ou implícitas, são direcionadas a professores de física da educação básica. Os discursos analisados foram obtidos em periódico, ata de encontro e através de entrevistas e questionário. Todos foram formulados em situações relacionadas com o ensino da física, no Brasil, em diferentes momentos desde a segunda metade do século passado. Entre as considerações que o estudo permite inferir, destacase a contribuição da participação na área de educação em ciências na superação das prescrições.

    2012-08-01

    Full Text Available Este trabalho teve o objetivo de investigar, a partir da teoria das representações sociais, as ideias de senso comum que circulam entre professores acerca do autismo infantil. Buscamos compreender a lógica interna de tais teorias populares, mapear os saberes que as apoiam e as imagens que as concretizam. Os 16 participantes do estudo compuseram dois grupos: 9 professoras experientes na educação de crianças autistas e 7 professores sem experiência com tais crianças. Os dados obtidos através de entrevistas semi-estruturadas permitem concluir que paradoxalmente, a aproximação com o objeto não parece conduzir a uma maior familiarização. De maneira geral, há incertezas e fluidez quanto a considerar o autismo uma desordem orgânica ou o resultado de complicações relacionais precoces; em acreditar que essas crianças apresentam inteligência acima da média ou deficiência intelectual. Os professores constroem, assim, autismos diversos, num processo de conhecimento ancorado em variados repertórios, dentre eles, a psicanálise e neurociências.

No segundo semestre de 2016 e primeiro de 2017, foi realizada uma entrevista com um professor de cada área do conhecimento. O material discursivo foi analisado com a técnica do Discurso do Sujeito Coletivo – DSC. No discurso sobre a compreensão de politecnia, os professores apresentam questionamentos que evidenciam uma não apropriação desse conceito, delegando à equipe diretiva a responsabilidade por explicar o mesmo. Associam a politecnia ao ensino de diversas técnicas que preparam para o mercado de trabalho ou a integração das áreas do conhecimento. O estudo aponta que as diferentes propostas de reestruturação curriculares implementadas, como a do Ensino Médio Politécnico (2012 e a Base Nacional Comum Curricular (2017 são capazes de gerar confusão entre culturas por trazerem à tona questionamentos sobre as ideias, tecnologias e organização social da escola e potencializar o surgimento de outras culturas de formação docente.

    X-linked ocular albinism can be an unsuspected cause of congenital nystagmus in blacks. In this study, eight of ten black ocular albinos from two kindreds had nonalbinotic, moderately pigmented fundi and no transillumination of the iris. We refer to this paradoxical condition as "ocular albinism cum pigmento." The only constant ophthalmoscopic feature was a foveal hypoplasia. Biopsy of clinically normal skin to demonstrate giant pigment granules is the most accurate means of diagnosis.

Professor de Hevesy was born in Budapest in 1885. He studied in Budapest, Berlin and Freiburg, and spent some years at Zurich when Einstein was there. In 1911 he went to Manchester to work with Rutherford and there witnessed some of the greatest discoveries in the history of physics. At the end of 1912 he visited the Vienna Institute for Radium Research, where he worked with Paneth, and in 1913 applied the method of labelled lead for the first time. After the first world war, he worked at the Institute for Theoretical Physics in Copenhagen; since 1943, his chief activities have been in Sweden. In 1923, with Coster, he discovered the element hafnium. He made notable discoveries on the mobility of ions, and isotope separation, and his work on radioisotope tracers, which has had important biological applications, won him the Nobel Prize for Chemistry in 1943

  6. Update on ocular toxicity of ethambutol

    Full Text Available The purpose of this review is to update clinicians on available literature on the ocular toxicity of ethambutol and the type of eye care to be provided to patients treated with these medications. Ethambutol is a commonly used first-line anti-tuberculosis drug. Since its first use in the 1960s, ocular toxicity is described as related to dose and duration, and it is reversible on therapy discontinuation. However, the reversibility of the toxic optic neuropathy remains controversial. The mechanism of ocular toxicity owing to ethambutol is still under investigation. Other than discontinuing the drug, no specific treatment is available for the optic neuropathy caused by ethambutol. Doctors prescribing ethambutol should be aware of the ocular toxicity, and the drug should be used with proper patient education and ophthalmic monitoring.

    The topical route is the most frequent and preferred way to deliver drugs to the eye. Unfortunately, the very low ocular drug bioavailability (less than 5%) associated with this modality of administration, makes the efficient treatment of several ocular diseases a significant challenge. In the last decades, it has been shown that specific nanocarriers can interact with the ocular mucosa, thereby increasing the retention time of the associated drug onto the eye, as well as its permeability across the corneal and conjunctival epithelium. In this review, we comparatively analyze the mechanism of action and specific potential of the most studied nano-drug delivery carriers. In addition, we present the success achieved until now using a number of nanotherapies for the treatment of the most prevalent ocular pathologies, such as infections, inflammation, dry eye, glaucoma, and retinopathies.

    Ocular melanoma is a rare malignancy found in clinical practice. In this paper, we present a case of highly aggressive ocular melanoma, which was surgically removed at the Department of Ophthalmology and diagnosed at the Department of Pathology, Emergency University Hospital, Bucharest, Romania, using conventional histopathological techniques. Uveal melanoma, a subset of ocular melanoma, has a distinct behavior in comparison to cutaneous melanoma and has a widely divergent prognosis. Approximately half of patients with ocular melanoma will develop metastatic disease, predominantly with hepatic, pulmonary or cerebral location, over a 10 to 15 years period. No systemic therapy was associated with an evident clinical outcome for patients with advanced disease and overall survival rate remains poor.

    Full Text Available Xeroderma pigmentosum (XP is a rare genetic disorder associated with multiple oculocutaneous and neurological manifestations. It occurs due to deficiency of the enzymes responsible for repairing ultraviolet radiation-induced DNA damage. Persistence of un-repaired DNA results in somatic mutations, leading to neoplasia of the skin and ocular surface. As this condition is rare, only isolated case reports of XP with ocular surface squamous neoplasia (OSSN are found in literature.

But if there were a society whose technological development determined radical transformations in the production and dissemination of knowledge, to the point of decisively changing the relations between teachers and students? Would the teacher continue to represent a model of identity for the student who could access information online in any time and space? In view of the context of the digital culture society, the objective of this article is to investigate how students practice cyberbullying in relation to their teachers through images recorded by mobile phones, which are posted on the site YouTube. It will be analyzed three videos posted by students from three different countries (Brazil, Portugal and England, whose images refer to situations experienced with their respective teachers. It is also intended to argue that such attitudes are signs of radical transformations that are occurring in relation to the way students identify the teacher as a pedagogical authority.

    Full Text Available In the last years, higher education teacher training has received more didactic-pedagogical attention. Despite numerous criticisms to professors' work, some practices present differentials that make them a reference to students, even among university professors with undergraduate and graduate degrees in their specific areas of knowledge. To analyze the classes of such professors who become a reference to students, we selected two higher education professors of chemistry and videotaped their classes seeking to identify the teaching strategies that they use. After analysis, we shared the results with the subjects and complemented them with a semi-structured interview. We found out that these professors perform based on counter-models of professors who they had had in their undergraduate courses and developed strategies aiming to minimize for their students the difficulties they themselves had experienced.

    To investigate the patterns and risk factors of the ocular manifestations of acquired immunodeficiency syndrome (AIDS) and their correlation with CD4+ count in the era of highly active antiretroviral therapy (HAART). This retrospective study examined 127 AIDS patients who presented to Soonchunhyang University Hospital. Data were collected from patient interviews, clinical examinations, and laboratory investigations. Ophthalmologic examinations included the best-corrected visual acuity, intraocular pressure, anterior segment and adnexal examination, and dilated fundus examination. Of the 127 patients with AIDS, 118 were on HAART and 9 were not. The mean CD4+ count was 266.7 ± 209.1 cells/µL. There were ocular manifestations in 61 patients (48.0%). The incidence of anterior segment manifestations was higher than posterior segment manifestations at 28.3% and 19.7%, respectively. The mean CD4+ count was significantly (p AIDS. In this study, anterior segment and external ocular manifestations occurred more frequently than posterior segment manifestations. Also, the mean CD4+ count was significantly lower in patients with posterior segment ocular manifestations versus anterior segment ocular manifestations. We found that CD4+ count and age >35 years were independent risk factors for developing ocular manifestations.

    To investigate the changes of predictive ocular motor function in the patients with Parkinson's disease (PD), and to discuss its clinical value. Videonystagmography (VNG) was used to examine 24 patients with idiopathic Parkinson's disease, 15 males and 9 females, aged 61 +/- 6 (50-69), and 24 sex and age-matched healthy control subjects on random ocular saccade (with the target moving at random intervals to random positions) and predictive ocular saccade (with the 1.25-second light target moving 10 degrees right or left from the center). In the random ocular saccade program, the latency of saccade of the PD patients was 284 ms +/- 58 ms, significantly longer than that of the healthy controls (236 ms +/- 37 ms, P = 0.003). In the predictive ocular saccade pattern, the latency of saccades the PD patients was 150 ms +/- 138 ms, significantly longer than that of the healthy controls (59 ms +/- 102 ms, P = 0.002). The appearance rate of predictive saccades (with the latency of saccade <80 ms) in the PD group was 21%, significantly lower than that in the control group (31%, P = 0.003). There is dysfunction of predictive ocular motor control in the PD patients, and the cognitive function may be impaired at the early stage of PD.

Pesquisas recentes têm celebrado essa mídia como um excelente recurso para professores com o objetivo supracitado (MEDEIROS, 2006; SOUZA; MARTINS,2007; UCHOA, 2010. Neste trabalho, que faz parte de um projeto maior intitulado “O uso de podcasts na educação continuada de professores de línguainglesa”, apresentamos a análise dos podcasts produzidos por professores em formação continuada durante um curso projetado para dar suporte aos professores com algumas ferramentas tecnológicas digitais emergentes. Em primeiro lugar, apresentamos nosso referencial teórico-metodológico, baseado principalmente no Interacionismo Sociodiscursivo (ISD. Em seguida, trazemos a discussão dos resultados, que aponta que o ensino com base em gêneros textuais proposto pelo ISD alcançou seu objetivo, o de preparar os professores para que possam utilizar a ferramenta podcast com propriedade e destreza. Os resultados também apontam que alguns dos professores ainda precisam melhorar suas habilidades de produção oral para trabalhar com mídias e gêneros textuais orais. Além disso, chegamos à conclusão de que o uso de tecnologias emergentes ainda precisa vencer algumas barreiras.

  1. Professor Gender, Age, and “Hotness” in Influencing College Students’ Generation and Interpretation of Professor Ratings

    Full Text Available Undergraduate psychology students rated expectations of a bogus professor (randomly designated a man or woman and hot versus not hot based on an online rating and sample comments as found on RateMyProfessors.com (RMP. Five professor qualities were derived using principal components analysis (PCA: dedication, attractiveness, enhancement, fairness, and clarity. Participants rated current psychology professors on the same qualities. Current professors were divided based on gender (man or woman, age (under 35 or 35 and older, and attractiveness (at or below the median or above the median. Using multivariate analysis of covariance (MANCOVA, students expected hot professors to be more attractive but lower in clarity. They rated current professors as lowest in clarity when a man and 35 or older. Current professors were rated significantly lower in dedication, enhancement, fairness, and clarity when rated at or below the median on attractiveness. Results, with previous research, suggest numerous factors, largely out of professors’ control, influencing how students interpret and create professor ratings. Caution is therefore warranted in using online ratings to select courses or make hiring and promotion decisions.

    To determine the ocular changes related to hypothyrodism in newly diagnosed patients without orbitopathy. Thirty-three patients diagnosed to have primary overt hypothyroidism were enrolled in the study. All subjects were assigned to underwent central corneal thickness (CCT), anterior chamber volume, depth and angle measurements with the Scheimpflug camera (Pentacam, Oculus) and cup to disc ratio (C/D), mean retinal thickness and mean retinal nerve fiber layer (RNFL) thickness measurements with optical coherence tomography (OCT) in addition to ophthalmological examination preceeding the replacement therapy and at the 1(st), 3(rd )and 6(th )months of treatment. The mean age of the patients included in the study were 40.58 +/- 1.32 years. The thyroid hormone levels return to normal levels in all patients during the follow-up period, however the mean intraocular pressure (IOP) revealed no significant change. The mean CCT was 538.05 +/- 3.85 mu initially and demonstrated no statistically significant change as the anterior chamber volume, depth and angle measurements did. The mean C/D ratio was 0.29 +/- 0.03 and the mean retinal thickness was 255.83 +/- 19.49 mu initially and the treatment did not give rise to any significant change. The mean RNFL thickness was also stable during the control visits, so no statistically significant change was encountered. Neither hypothyroidism, nor its replacement therapy gave rise to any change of IOP, CCT, anterior chamber parameters, RNFL, retinal thickness and C/D ratio.

    Ocular allergy (OA) includes a group of common and less frequent hypersensitivity disorders frequently misdiagnosed and not properly managed. The diagnosis of OA is usually based on clinical history and signs and symptoms, with the support of in vivo and in vitro tests when identification of the specific allergen is required. To date, no specific test is available for the diagnosis of the whole spectrum of the different forms of OA. The lack of recommendations on diagnosis of OA is considered a medical need not only for allergists but also for ophthalmologists. This position paper aims to provide a comprehensive overview of the currently available tools for diagnosing OA to promote a common nomenclature and procedures to be used by different specialists. Questionnaires, sign and symptom grading scales, tests, and potential biomarkers for OA are reviewed. We also identified several unmet needs in the diagnostic tools to generate interest, increase understanding, and inspire further investigations. Tools, recommendations, and algorithms for the diagnosis of OA are proposed for use by both allergists and ophthalmologists. Several unmet needs in the diagnostic tools should be further improved by specific clinical research in OA. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

    Full Text Available Academics who hold positions at single-mode, distance education institutions are presently being hampered by an adherence to a long-standing set of protocols (specific office location, face-to-face meetings that were put in place when the conventional post-secondary was the norm. With the advent of a powerful merging of personal computers and the internet, a shift from those protocols to one of support for the virtual professor is in the offing, to the benefit of both the professoriate and the student. A key factor in this shift is the degree and quality of institutional support that will allow these changes to take place. This paper focuses on a number of the key factors that will have to be addressed if this new type of distance education academic is to function effectively.

In particular, the situation in Switzerland, where mains-connected sources of energy such as electricity and gas play an important role in energy supply, is looked at in the light of market liberalisation. Various approaches to the liberalisation of gas and electricity systems are discussed and the costs of liberalised supply systems are compared with those of the present monopolistic situation. Also, energy reserves and the use of the gas distribution system in a future hydrogen-based energy supply scenario are looked at. Projects currently being worked on at the CEPE are reviewed

  9. Ocularity Feature Contrast Attracts Attention Exogenously

    2018-02-01

    Full Text Available An eye-of-origin singleton, e.g., a bar shown to the left eye among many other bars shown to the right eye, can capture attention and gaze exogenously or reflexively, even when it appears identical to other visual input items in the scene and when the eye-of-origin feature is irrelevant to the observer’s task. Defining saliency as the strength of exogenous attraction to attention, we say that this eye-of-origin singleton, or its visual location, is salient. Defining the ocularity of a visual input item as the relative difference between its left-eye input and its right-eye input, this paper shows the general case that an ocularity singleton is also salient. For example, a binocular input item among monocular input items is salient, so is a left-eye-dominant input item (e.g., a bar with a higher input contrast to the left eye than to the right eye among right-eye-dominant items. Saliency by unique input ocularity is analogous to saliency by unique input colour (e.g., a red item among green ones, as colour is determined by the relative difference(s between visual inputs to different photoreceptor cones. Just as a smaller colour difference between a colour singleton and background items makes this singleton less salient, so does a smaller ocularity difference between an ocularity singleton and background items. While a salient colour difference is highly visible, a salient ocularity difference is often perceptually invisible in some cases and discouraging gaze shifts towards it in other cases, making its behavioural manifestation not as apparent. Saliency by ocularity contrast provides another support to the idea that the primary visual cortex creates a bottom-up saliency map to guide attention exogenously.

Findings Thirty-three patients diagnosed to have primary overt hypothyroidism were enrolled in the study. All subjects were assigned to underwent central corneal thickness (CCT, anterior chamber volume, depth and angle measurements with the Scheimpflug camera (Pentacam, Oculus and cup to disc ratio (C/D, mean retinal thickness and mean retinal nerve fiber layer (RNFL thickness measurements with optical coherence tomography (OCT in addition to ophthalmological examination preceeding the replacement therapy and at the 1st, 3rd and 6th months of treatment. The mean age of the patients included in the study were 40.58 ± 1.32 years. The thyroid hormone levels return to normal levels in all patients during the follow-up period, however the mean intraocular pressure (IOP revealed no significant change. The mean CCT was 538.05 ± 3.85 μ initially and demonstrated no statistically significant change as the anterior chamber volume, depth and angle measurements did. The mean C/D ratio was 0.29 ± 0.03 and the mean retinal thickness was 255.83 ± 19.49 μ initially and the treatment did not give rise to any significant change. The mean RNFL thickness was also stable during the control visits, so no statistically significant change was encountered. Conclusions Neither hypothyroidism, nor its replacement therapy gave rise to any change of IOP, CCT, anterior chamber parameters, RNFL, retinal thickness and C/D ratio.

    Dust exposure is a well-known occupational hazard for terrestrial workers and astronauts alike and will continue to be a concern as humankind pursues exploration and habitation of objects beyond Earth. Humankind's limited exploration experience with the Apollo Program indicates that exposure to dust will be unavoidable. Therefore, NASA must assess potential toxicity and recommend appropriate mitigation measures to ensure that explorers are adequately protected. Visual acuity is critical during exploration activities and operations aboard spacecraft. Therefore, the present research was performed to ascertain the ocular toxicity of authentic lunar dust. Small (mean particle diameter = 2.9 ± 1.0 μm), reactive lunar dust particles were produced by grinding bulk dust under ultrapure nitrogen conditions. Chemical reactivity and cytotoxicity testing were performed using the commercially available EpiOcularTM assay. Subsequent in vivo Draize testing utilized a larger size fraction of unground lunar dust that is more relevant to ocular exposures (particles lunar dust was minimally irritating. Minor irritation of the upper eyelids was noted at the 1-hour observation point, but these effects resolved within 24 hours. In addition, no corneal scratching was observed using fluorescein stain. Low-titanium mare lunar dust is minimally irritating to the eyes and is considered a nuisance dust for ocular exposure. No special precautions are recommended to protect against ocular exposures, but fully shielded goggles may be used if dust becomes a nuisance.

    It is with great sadness that we report the death of Jan Evetts, who lost his second battle with cancer on 18 August 2005. In 1988 he was appointed Founding Editor of this journal where his leadership created the foundation upon which its success rests today. He made an outstanding series of contributions to the science of superconductivity and to the understanding of superconducting materials, and was an indefatigable champion of the development of applications of superconductivity. The loss to the scientific community is incalculable, as is attested by the many communications received from colleagues throughout the world. Professor Jan Edgar Evetts (1939-2005) Professor Jan Edgar Evetts (1939-2005) Jan was born on 31 March 1939, and attended the Dragon School in Oxford, and later Haileybury. He was awarded an exhibition to read Natural Sciences at Pembroke College, Cambridge in 1958 and took his BA degree in 1961. He then undertook a Certificate of Postgraduate Study in Physics under the supervision of Professor Neville Mott. He was the first student to undertake this newly-instituted course; the title of his thesis was `The Resistance of Transition Metals'. In 1962 he joined David Dew-Hughes' embryonic superconducting materials research group, along with Archie Campbell and Anant Narlikar. In fact it was Jan's enthusiasm for the proposed course of research that helped convince David that he should follow Professor Alan Cottrell's suggestion to apply metallurgical methodology to the study of the factors that controlled critical current density in the type II superconductors that were then under development for applications in magnets. Competing theories for the critical current density at that time were fine filaments or `Mendelssohn Sponge' versus the pinning of Abrikosov quantized vortices. The results of the group's work, to which Jan made a major contribution, came down heavily in favour of the latter theory. Jan's outstanding characteristic was his

    2018-03-01

    Of the 3,548 known mosquito species, about 100 transmit human diseases. Mosquitoes are distributed globally throughout tropical and temperate regions where standing water sources are available for egg laying and the maturation of larva. Female mosquitoes require blood meals for egg production. This is the main pathway for disease transmission. Mosquitoes carry several pathogenic organisms responsible for significant ocular pathology and vision loss including West Nile, Rift Valley, chikungunya, dengue viruses, various encephalitis viruses, malarial parasites, Francisella tularensis, microfilarial parasites, including Dirofilaria, Wuchereria, and Brugia spp., and human botfly larvae. Health care providers may not be familiar with many of these mosquito-transmitted diseases or their associated ocular findings delaying diagnosis, treatment, and recovery of visual function. This article aims to provide an overview of the ocular manifestations associated with mosquito-transmitted diseases.

    Newer CT scans have greatly enhanced oculometric research and made it possible to measure ocular dimensions. With these measurements, ocular volume can be more accurately estimated to understand its relationship with age and sex. One hundred CT orbit scans with presumed normal eyes were used for the data base. The mean values and normal variations of ocular volumes at various ages in both sexes are presented. Rapid growth of the eyeball was noted during the first 24 months of age. It reached its peak between the ages of 18 and 30 years of age, after which there was a reduction. Results may be of help in recognizing eye abnormalities such as microophthalmus and macrophthalmia. (orig.)

    1994-05-01

    Histologic evaluation of four eyes from three stranded juvenile green turtles (Chelonia mydas) from Florida, USA revealed ocular fibropapillomas composed of an overlying hyperplastic epithelium, various amounts of a thickened, well vascularized, collagenous stroma, and a moderate-to-dense population of reactive fibroblasts. The histologic morphology of the ocular fibropapillomas varied depending on whether the eyelid, conjunctiva, limbus, or cornea was the primary site of tumor origin. Fibropapillomas arising from the limbus, conjunctiva, or eyelid tended to be polyploid or pedunculated with a high degree of arborization. They often filled the conjunctival fornices and extended externally to be ulcerated on the distal aspects. Corneal fibropapillomas were more sessile and multinodular with less arborization. Some corneal tumors consisted primarily of a broad fibrovascular stroma and mild epithelial hyperplasia, whereas others had a markedly hyperplastic epithelium supported by stalks of fibrovascular stromal tissue. In green turtles ocular fibropapillomas may be locally invasive and associated with severe blindness and systemic debilitation.

    Full Text Available Victoria Mary Lendrum CohenSt. Bartholomew’s and Moorfields Eye Hospital, London UKAbstract: Most lymphomas that involve the ocular adnexal structure are low grade, B cell, non-Hodgkin’s lymphomas. The treatment depends upon the grade and stage of the disease. High grade lymhoma requires treatment with systemic chemotherapy whereas the localized low grade (extranodal marginal zone lymphoma can be successfully managed with local radiotherapy. Chlamydia psittaci infection is associated with low grade ocular lymphoma; however there is wide geographic variation in the strength of this association. Blanket antibiotic therapy is not advised unless there is proof of an infective agent.

    2015-10-01

    The proficiency of nonophthalmologists with direct ophthalmoscopy is poor, which has prompted a search for alternative technologies to examine the ocular fundus. Although ocular fundus photography has existed for decades, its use has been traditionally restricted to ophthalmology clinical care settings and textbooks. Recent research has shown a role for nonmydriatic fundus photography in nonophthalmic settings, encouraging more widespread adoption of fundus photography technology. Recent studies have also affirmed the role of fundus photography as an adjunct or alternative to direct ophthalmoscopy in undergraduate medical education. In this review, the authors examine the use of ocular fundus photography as an educational tool and suggest future applications for this important technology. Novel applications of fundus photography as an educational tool have the potential to resurrect the dying art of funduscopy. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Full Text Available Transport of drugs applied by traditional dosage forms is restricted to the eye, and therapeutic drug concentrations in the target tissues are not maintained for a long duration since the eyes are protected by a unique anatomy and physiology. For the treatment of the anterior segment of the eye, various droppable products to prolong the retention time on the ocular surface have been introduced in the market. On the other hand, direct intravitreal implants, using biodegradable or non-biodegradable polymer technology, have been widely investigated for the treatment of chronic vitreoretinal diseases. There is urgent need to develop ocular drug delivery systems which provide controlled release for the treatment of chronic diseases, and increase patient’s and doctor’s convenience to reduce the dosing frequency and invasive treatment. In this article, progress of ocular drug delivery systems under clinical trials and in late experimental stage is reviewed.

    Eye cosmetics usage is commonplace and whilst some products such as eyeliner are applied with close proximity to the ocular surface, there is little knowledge of the short- and long-term ocular effects of eye cosmetic formulations. This study aimed to investigate the use of eye cosmetics and identify any relationships between ocular comfort and cosmetic usage. Results were collated from an online survey comprising 23 questions that recorded demographics, Ocular Surface Disease Index (OSDI) score, extent and range of eye cosmetic use and perceived comfort differences with and without eye cosmetics. The 1360 female respondents (median age 25, interquartile range 20-34 years) completed the survey; 83% reported using eye cosmetics regularly (≥ 3 times per week) with mascara being most commonly used. Fifty three per cent used at least three different eye cosmetics products regularly. OSDI scores of cosmetics users were similar to non-users (p = 0.083), but perceived comfort was greater when cosmetics were not used (p cosmetics users (use of products cosmetics were used. Median OSDI scores suggested a trend towards reduced comfort amongst eyeliner users (p = 0.07) although frequency and type of cosmetic products used did not appear to influence OSDI scores. This study shows the use of multiple eye cosmetics is extensive and associated with the perception of ocular discomfort. With such widespread use of these products, more research is required to assess the effect on the ocular surface and tear film, which may be underestimated.

    Keratoconjunctivitis sicca, or dry eye, is a common ocular disease prompting millions of individuals to seek ophthalmological care. Regardless of the underlying etiology, dry eye has been shown to be associated with abnormalities in the pre-corneal tear film and subsequent inflammatory changes in the entire ocular surface including the adnexa, conjunctiva and cornea. Since the recognition of the role of inflammation in dry eye, a number of novel treatments have been investigated designed to inhibit various inflammatory pathways. Current medications that are used, including cyclosporine A, corticosteroids, tacrolimus, tetracycline derivatives and autologous serum, have been effective for management of dry eye and lead to measurable clinical improvement.

    Usual magnetic isotope-separators select the particles with the same Z/A value which may include different nuclides. Identification of the isotope with the same Z/A value but different Z or A value is an universal requirement for nuclear physics experiments. If one knows, together with the A/Z value, the dE/dx or the range of the isotope in some energy absorber, which are the function of Z 2 /A, its nuclide can be specified. This idea can be realized by arranging proper energy-absorber at the focal point of magnetic analyzer. The author proposes another novel method in which two dipole-magnets are excited with some difference, and an energy absorber corresponding to that energy difference is situated between two magnets. It can also be devised so that the dispersion at the final focal-point depends only on the emission angle of the isotope at production. Professor Sugimoto recognized the significance of this scheme and proposed to employ it in the experiment at BEVATRON. The unbalanced two dipole-magnets method is employed at RIKEN and RCNP, Osaka University. The author's creative idea originated in Sugimoto Laboratory at Osaka University. (author)

    A few days before the beginning of the 7th European Conference on Applied Superconductivity we learned that Professor Jan Evetts, a pioneer of superconductor research, a brilliant scientist, a wonderful person and a great personal friend, had passed away. We therefore decided to dedicate the 7th European Conference on Applied Superconductivity to the memory of Jan Evetts. The following citation is based on material provided by his former supervisor (D Dew-Hughes) and his closest co-workers in Cambridge. Professor Jan Edgar Evetts (1939-2005) Professor Jan Edgar Evetts (1939-2005) Jan Evetts passed away after losing his second battle with cancer on 24th August 2005. He made an outstanding series of contributions to the science of superconductivity and to the understanding of superconducting materials and was an indefatigable champion of the development of applications of superconductivity. The loss to the superconductivity community is incalculable, as attested by the many communications received from colleagues throughout the world. Jan was born on 31 March 1939, and attended the Dragon School in Oxford, and later Haileybury. He was awarded an exhibition to read Natural Sciences at Pembroke College, Cambridge. He entered the college in 1958 and took his BA degree in 1961. He then undertook a Certificate of Postgraduate Study in Physics under the supervision of Professor Neville Mott. He was the first student to undertake this newly-instituted course; the title of his thesis was `The Resistance of Transition Metals'. In 1962 he joined David Dew-Hughes' superconducting materials research group, along with Archie Campbell and Anant Narlikar. In fact it was Jan's enthusiasm for the proposed course of research that helped convince David that he should follow Professor Alan Cottrell's suggestion to apply metallurgical methodology to the study of the factors that controlled critical current density in the type II superconductors that were then under development for

    EntreMed has licensed the worldwide rights to the angiogenesis inhibitor Endostatin, a 20 kDa C-terminal fragment of collagen XVIII, from the Children's Hospital of Boston, a teaching affiliate of Harvard Medical School. It is being developed as a potential cancer treatment and may also be useful in certain types of blindness and arthritis [227427]. EntreMed filed an IND for Endostatin in June 1999 [334125] and as of September 1999, phase I trials were underway [341462]. As of April 2000, the company had initiated plans for testing low doses of Endostatin in cancer patients using continuous infusion and sc administration in a further phase I study to be conducted in Europe [361594]. A phase I trial of Endostatin which will evaluate the safety and efficacy of Endostatin at a range of doses in no more than 100 cancer patients has been initiated. The trial will take place at the University of Texas MD Anderson Medical Center and the University of Wisconsin Cancer Center in Madison. The National Cancer Center will be sponsoring the trial, which is expected to be completed in late 2000. As of March 2000, there had been no serious adverse events attributable to Endostatin administration. The first report from this trial is expected in autumn 2000 [341462], [366312]. The mechanism of action for Endostatin remains unclear, although reports from the 91st AACR Meeting in April 2000 showed that recombinant human endostatin bound to a number of tropomyosin cDNAs in a library screen [362039]. In preclinical studies, repeated administration of Endostatin consistently shrank primary tumors and did not produce any drug resistance. In mice, a variety of tumors which had progressed to 1 to 2% of total body weight, regressed to microscopic, dormant lesions following Endostatin treatment [231418], [231470], [270673]. Types of cancers which respond to Endostatin include lung, skin, vascular and fibrosarcomas. Toxicology studies in cynomolgus monkeys showed that bolus injections of

    1992-01-01

    In 26 random out-patients, including 13 treated glaucoma patients and ocular hypertensives, the higher the ocular tension, the greater the pulse amplitude, by Alcon pneumotonometry, at a statistically significant level. In a single untreated hypertensive, when 2-hourly pneumotonometry was done for 24 h, the correlation was similar and significant. The higher the diastolic blood pressure, the higher the ocular pulsation, also significantly. Pulsation is suggested to be a pump, the choroid being the piston, contributing (1) to an increase in the outflow of aqueous humour and (2) to a homeostatic mechanism contributing to normalization of the intra-ocular pressure, wherein pulsation increases or decreases, as the intraocular pressure increases or decreases, respectively.

Methods: This prospective study was conducted between January and December 2009. Federal Medical Center, Owo is the only tertiary hospital in Ondo State, Nigeria. The eye center located at this medical center was the only eye care facility in the community at the time of this study. All patients were interviewed with the aid of an interviewer-administered questionnaire and underwent a detailed ocular examination. Results: Of 132 patients included in the study, most (84.1% sustained blunt eye injury while (12.1% had penetrating eye injury. A considerable proportion of patients (37.9% presented within 24 hours of injury. Vegetative materials were the most common (42.4% offending agent, a minority of patients (22% was admitted and none of the patients had used eye protection at the time of injury. Conclusion: In the current series, blunt eye injury was the most common type of ocular trauma. The community should be educated and informed about the importance of preventive measures including protective eye devices during high risk activities. Patients should be encouraged to present early following ocular injury.

    To prospectively study mechanisms and injury characteristics of ocular firework burns. A prospective analysis of all patients with firework injuries attending the Department of Ophthalmology, University of Vienna, between 1994 and 2001. We looked for classes of fireworks and mechanisms of injuries. The number of diagnoses was established and their severity classified. During this period (8 years) we identified 116 eyes of 102 patients. 67/102 (66%) of all injuries were caused by class II and III fireworks. Patients ranged between 4 and 83 years. Ocular injuries occurred more frequently in males (69, 68%) and affected the right eye in 53 patients (52.5%). Ocular firework injuries to minors (under the age of 18 years) occurred in 48 (49%). The most common types of injury were skin and corneal erosions and abrasions (32/116, 28%). 11/116 eyes (10%) had severe injuries. 8 of 11 severe injuries (72%) occurred in minors (<18 years). 2 patients (1.7%) developed permanent blindness. In 32/116 patients (28%), the ocular trauma resulted in visual impairment, mainly due to corneal scars or retinal pathologies. In all patients, the severity index was 1.4 +/- 0.8. In minors the severity index was 1.6 +/- 1.0, in adults 1.2 +/- 0.5 (p = 0.013). Injuries in minors were significantly more severe than those in adults. Possible preventive measures include legislation, education of minors and eye protection. Copyright 2002 S. Karger AG, Basel

  2. Systematic analysis of ocular trauma by a new proposed ocular trauma classification

    2017-01-01

    Full Text Available Purpose: The current classification of ocular trauma does not incorporate adnexal trauma, injuries that are attributable to a nonmechanical cause and destructive globe injuries. This study proposes a new classification system of ocular trauma which is broader-based to allow for the classification of a wider range of ocular injuries not covered by the current classification. Methods: A clinic-based cross-sectional study to validate the proposed classification. We analyzed 535 cases of ocular injury from January 1, 2012 to February 28, 2012 over a 4-year period in an eye hospital in central India using our proposed classification system and compared it with conventional classification. Results: The new classification system allowed for classification of all 535 cases of ocular injury. The conventional classification was only able to classify 364 of the 535 trauma cases. Injuries involving the adnexa, nonmechanical injuries and destructive globe injuries could not be classified by the conventional classification, thus missing about 33% of cases. Conclusions: Our classification system shows an improvement over existing ocular trauma classification as it allows for the classification of all type of ocular injuries and will allow for better and specific prognostication. This system has the potential to aid communication between physicians and result in better patient care. It can also provide a more authentic, wide spectrum of ocular injuries in correlation with etiology. By including adnexal injuries and nonmechanical injuries, we have been able to classify all 535 cases of trauma. Otherwise, about 30% of cases would have been excluded from the study.

    Full Text Available Com os avanços da cirurgia para catarata, o prognóstico da recuperação da visão aumentou drasticamente, tornando-se necessário prever resultados indesejados para a acuidade visual no pós-operatório. OBJETIVOS: Verificar a importância da ultra-sonografia ocular na avaliação pré-operatória do segmento posterior em pacientes com catarata madura, e relacionar possíveis doenças que possam comprometer os resultados cirúrgicos, sua prevalência e seus principais fatores de risco. MÉTODOS: Foi realizado estudo retrospectivo do prontuário de 262 pacientes em que houve a necessidade de ultra-sonografia ocular devido à presença de catarata madura, impedindo assim a avaliação fundoscópica do segmento posterior. Também foi avaliada a relação entre a presença dessas alterações e o sexo, idade, raça, história de trauma ocular, doenças sistêmicas e oculares e presença de catarata no olho contralateral. RESULTADOS: Encontraram-se alterações ecográficas em 24,8% dos exames realizados entre 1996 e 2001, dos quais o descolamento de retina (9,9% e as condensações vítreas (9,9% foram as mais comuns. CONCLUSÕES: Dentre os fatores de risco levantados como predisponentes para achados de ultra-sonografia ocular, a uveíte foi o único elemento estatisticamente significante. Não foi possível, pelos dados obtidos, correlacionar positivamente o trauma ocu-lar às patologias de segmento posterior descritas.With the new techniques of cataract surgery visual success has increased and it became necessary to foresee undesirable postoperative results regarding visual acuity.

    Abstract Professor Stuart A. Lipton Stuart A. Lipton, M.D., Ph.D. is recognized here as a Redox Pioneer because of his publication of four articles that have been cited more than 1000 times, and 96 reports which have been cited more than 100 times. In the redox field, Dr. Lipton is best known for his work on the regulation by S-nitrosylation of the NMDA-subtype of neuronal glutamate receptor, which provided early evidence for in situ regulation of protein activity by S-nitrosylation and a prototypic model of allosteric control by this post-translational modification. Over the past several years, Lipton's group has pioneered the discovery of aberrant protein nitrosylation that may contribute to a number of neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (Lou Gehrig's disease). In particular, the phenotypic effects of rare genetic mutations may be understood to be enhanced or mimicked by nitrosative (and oxidative) modifications of cysteines and thereby help explain common sporadic forms of disease. Thus, Lipton has contributed in a major way to the understanding that nitrosative stress may result from modifications of specific proteins and may operate in conjunction with genetic mutation to create disease phenotype. Lipton (collaborating with Jonathan S. Stamler) has also employed the concept of targeted S-nitrosylation to produce novel neuroprotective drugs that act at allosteric sites in the NMDA receptor. Lipton has won a number of awards, including the Ernst Jung Prize in Medicine, and is an elected fellow of the AAAS. Antioxid. Redox Signal. 19, 757–764. PMID:23815466

    This dissertation deals with Ellen Gleditsch and some important aspects of her career, as professor, radiochemist and mentor. As Professor Gleditsch supervised students, gave lectures, disseminated science, did research and administrative work; together with many others she participated in the shaping of a research university which developed during her career. She also experienced the daily life in an institute in which there was competition for both resources and positions, included the professorship she was finally granted after many set-backs. The Radiochemist Ellen Gleditsch worked and researched at Marie Curie's laboratory in Paris, and later at Bertram Boltwood's laboratory in New Haven and Stefan Meyer's Institute for Radium Research in Vienna, furthermore she planned and made efforts to establish a similar laboratory in Oslo. During her time in Paris and U.S.A. Gleditsch participated in important debates in the early period of radioactivity, including those on the determination of the radium-uranium ratio and the half-life of radium. In Norway she devoted her time to atomic weight determinations, age determinations, and radiogeological investigations. Research was all important part of Gleditsch's life and career. Gleditsch was also a Mentor in many respects; in tile international radioactivity community, as one of the first female academics and radiochcmists in Norway, for her many students, and this role seems also to have been hers within her family. In Paris she looked after students from all over the world to help alleviate their home sickness, at the University of Oslo she was known as the scientific mother to many; mentoring was among Gleditsch's main qualities. The story of Ellen Gleditsch opens for several perspectives that are discussed. 3 papers are included. In paper 1, ''Ellen Gleditsch: Pioneer Woman in Radiochemistry'', the story is about the young chemist Ellen Gleditsch, who arrived in Paris in 1907 and started cooperating with Marie Curie

    Full Text Available AIM: To report the frequency, associated risk factors and characteristics of cases referred to Farabi Eye Hospital with ocular superglue injuries. METHODS: In a descriptive cross-sectional study conducted between December 2012 and February 2013, patients with ocular superglue injuries were evaluated. Age, sex, educational level, location, time, mechanism, type, site and time of eye injury were gathered through interview using a customized questionnaire. All participants had given consent to undergo thorough eye examination. RESULTS: Over the course of three months, 105 patients with ocular superglue injuries enrolled in the study, including 56(53.3% men and 49(46.7% women with the mean age of 24.7±11.6 (range, 2 to 53y. The right eye, left eye and both eyes were involved in 52%, 42% and 6% of the patients, respectively. Most of injuries had occurred at home (72.4% and at night (55%. More than half of patients (52.4% did not take any primary aids following the ocular injury. Patient carelessness (78.1%, childhood curiosity and lack of parental supervision (11.4%, storing superglue in inappropriate places and inadvertently using superglue as eye drops due to poor vision (2.9%, inadequate awareness of superglue applications [used to stick on artificial nails (3.8%, artificial eyelashes (1.9% and broken tooth (1%] and being assaulted with glue (1% were common risk factors. CONCLUSION: The frequency of ocular superglue injuries in patients referred to Farabi Eye Hospital is relatively high. This finding underlines the importance of public education and awareness about superglue injuries to the eye and taking protective measures and safety strategies in order to prevent these injures.

    Full Text Available Purpose: We report a rare case of ocular injury due to potassium permanganate (KMnO4 granules in a child. Methods: This is a retrospective case report. Results: A 2-year-old boy was transferred to our emergency room with severe pain in his right eye, inflamed eyelids, and brownish stains on his fingers. Chemical injury was suspected. Copious eye irrigation was immediately performed. Diffuse brownish splotches were then observed at the inferior bulbar conjunctiva. Otherwise, systemic organs were intact. Complete eye exam under general anesthesia revealed a 5-mm epithelial defect at the central cornea, along with generalized conjunctival injection and limbal ischemia, inferiorly. Multiple semi-dissolved granules of KMnO4 trapped in the inferior fornix were identified. The chemical particles were gradually washed out and removed; however, the brownish stains remained. The patient received preservative-free steroid, antibiotic eye drops, and lubricants as regular management for mild to moderate degree of ocular burn. Pseudomembrane developed early and transformed into symblepharon within a few days after the injury. Membrane adhesion was lysed, and more aggressive medications were then substituted. Commercial amniotic membrane (PROKERA® was also applied to promote wound healing and to prevent recurrence of symblepharon. The ocular surface was eventually restored, and corneal transparency was preserved. Conclusion: Ocular injury with the granular form of KMnO4 is rare. Its toxicity is comparable to concentrated KMnO4 solution. However, the dissolved particles that had been absorbed in the stained conjunctiva were continuously released and damaged the ocular surface more than we primarily anticipated. Awareness of this condition and prompt management yield a good treatment outcome.

    Full Text Available The article offers an analysis of the linguocultural character type professor taking into consideration both traditional set of signs and those transformations that indicate accumulation of evolutionary changes. The methodological base for the systematic description were the achievements of such areas of scientific knowledge as personology, linguopersonology and discourseology. The linguocultural character type (LCCT is a generalised image of persons, whose behaviour and value orientations influence culture, language and show social originality of the society. The peculiarity of the studied linguocultural character type is in its interrelation with the linguocultural character types intellectual and teacher as well as in the fact of the traditional connection with the concept elite. The exposure of such kind of multidimensional relations allowed to focus attention on the qualities of the LCCT professor that ensure its relative self-sufficiency. The sign of elitism and belonging to the intellectuals of the LCCT professor is asserted by the high social status recognised by the society, which is based on professionalism and compliance with moral principles. The axiological generality of the LCCT professor and teacher is ensured by the peculiarities of the modern pedagogical discourse with its typical image settings. One of the main features of the image of a professor is its belonging to the elite language person. The transformational processes in the contents of the LCCT professor are connected with the globalisation: including the international dimension in the evaluation of the professional activity, complication of the language environment, marketisation of the university sphere.

    To discuss the role of mathematical modeling in studying ocular hemodynamics, with a focus on glaucoma. We reviewed recent literature on glaucoma, ocular blood flow, autoregulation, the optic nerve head, and the use of mathematical modeling in ocular circulation. Many studies suggest that alterations in ocular hemodynamics play a significant role in the development, progression, and incidence of glaucoma. Although there is currently a limited number of studies involving mathematical modeling of ocular blood flow, regulation, and diseases (such as glaucoma), preliminary modeling work shows the potential of mathematical models to elucidate the mechanisms that contribute most significantly to glaucoma progression. Mathematical modeling is a useful tool when used synergistically with clinical and laboratory data in the study of ocular blood flow and glaucoma. The development of models to investigate the relationship between ocular hemodynamic alterations and glaucoma progression will provide a unique and useful method for studying the pathophysiology of glaucoma.

    Full Text Available El ojo es uno de los órganos más sensibles y está permanentemente expuesto a diversos agentes ambientales. Dado que la conjuntiva es un tejido inmunológicamente activo, no es sorprendente que sea un sitio común de respuestas alérgicas. Las alergias oculares son un grupo de enfermedades que afectan la superficie conjuntival y están asociadas usualmente a reacciones de hipersensibilidad tipo 1. Pueden ser divididas en varias categorías: conjuntivitis alérgica estacional, conjuntivitis alérgica perenne, queratoconjuntivitis vernal y queratoconjuntivitis atópica. La inflamación de la superficie ocular produce prurito, lagrimeo, edema conjuntival y fotofobia. Como en otras enfermedades alérgicas, se puede desarrollar una condición crónica, acompañada de remodelación de los tejidos oculares. Las estrategias para el tratamiento de la alergia ocular han aumentado exponencialmente y los clínicos disponen de un inventario cada vez mayor de agentes dirigidos a la protección del ojo contra la inflamación. En este trabajo presentamos una revisión sobre las principales formas de alergia ocular, haciendo énfasis en el cuadro clínico, el diagnóstico y las nuevas opciones terapéuticas disponibles en la actualidad. The eye, one of the most sensitive organs, is permanently exposed to different environmental agents. Since the conjunctiva is an immunologically active tissue, it is not surprising for it to be a common site for allergic responses. Ocular allergies constitute a group of diseases affecting the conjunctival surface; they are usually associated with type 1 hypersensitivity reactions. This disorder can be divided into several categories: seasonal allergic conjunctivitis, perennial allergic conjunctivitis, vernal keratoconjunctivitis and atopic keratoconjunctivitis. Ocular surface inflammation results in itching, tearing, conjunctival edema, and photophobia. As is the case with other allergic diseases, a chronic situation can also

    Full Text Available BACKGROUND In India, an estimated 1.5-2.5% children below 2 years of age are developmentally delayed. A higher incidence of ocular disability is seen in these children, refractive errors and strabismus being most common. These can add to the overall burden of health as most of them have developmental comorbidities. The aim of the study is to study the ocular disorders in children with developmental delay. MATERIALS AND METHODS We studied 112 children between the 2-12 years of age diagnosed to have developmental delay. All the subjects underwent a detailed ophthalmic evaluation including visual acuity testing using Snellen’s charts (3m and 6m and Log MAR charts (recorded as per Snellen’s vision testing to maintain uniformity, cycloplegic refraction, torchlight and slit-lamp evaluation and dilated fundus examination. The data was tabulated and represented using bar diagrams, Pie charts and graphs. The results were expressed as percentages. Design-Cross-sectional, observational study. RESULTS 66 boys and 46 girls (total 112 were evaluated. The mean age of the study population was 7.8 years ± 2.4 SD. The aetiology of developmental delay was cerebral palsy (64%, Down syndrome (22%, autism (7%, intellectual disability (4.5% and 1 case each of congenital hypothyroidism and ataxia telangiectasia. The prevalence of ocular disorders was found to be 84.8%, which was slightly higher in girls (87% as compared to boys (83%. Refractive error (79.5% was the commonest ocular disorder followed by strabismus (46.4%. Astigmatism (44.6% was the commonest refractive error, which was divided into myopic astigmatism (19.6%, hyperopic astigmatism (13.8% and mixed astigmatism (11.2%. Simple hyperopia was seen in 21.9% subjects and simple myopia in 12.1%. Exotropia (52% was commoner than esotropia (48%. Other ocular abnormalities included optic atrophy, nystagmus, epicanthal folds, cataract, mongoloid slant, ptosis, telecanthus, conjunctival telangiectasia and

    Full Text Available No presente trabalho são relatados seis casos de pacientes que cometeram auto-enucleação (cinco unilaterais e uma bilateral, acompanhados no serviço de psiquiatria do Hospital das Clínicas da Unicamp nos últimos dez anos. Além disso, é feita uma revisão da literatura relacionada a esse tipo de comportamento, considerado a forma mais grave e dramática de automutilação ocular. A partir da discussão crítica comparativa entre os aspectos clínicos de cada caso relatado e os dados encontrados na literatura, concluímos que se mostram associados à auto-enucleação: pacientes esquizofrênicos que cometeram a autolesão durante episódios psicóticos agudos, fortes elementos religiosos como parte da psicopatologia, evidências de comportamento automutilatório menos grave antes da auto-enucleação e explicação do ato como relacionado a uma suposta salvação do próprio paciente ou do mundo. Algumas outras características mais específicas de nossos casos também são destacadas: longo tempo de evolução da doença no momento da auto-enucleação; crenças religiosas variando entre três diferentes igrejas cristãs (Católica, Evangélica e Testemunhas de Jeová; presença de uma forma não usual de auto-enucleação com uso de arma de fogo e presença de um caso de auto-enucleação bilateral.

    Clark, B.; Randle, R. J.; Stewart, J. D.

    1975-01-01

    Stimulation of the vestibular system by angular acceleration produces widespread sensory and motor effects. The present paper studies a motor effect which has not been reported in the literature, i.e., the influence of rotary acceleration of the body on ocular accommodation. The accommodation of 10 young men was recorded before and after a high-level deceleration to zero velocity following 30 sec of rotating. Accommodation was recorded continuously on an infrared optometer for 110 sec under two conditions: while the subjects observed a target set at the far point, and while they viewed the same target through a 0.3-mm pinhole. Stimulation by high-level rotary deceleration produced positive accommodation or a pseudomyopia under both conditions, but the positive accommodation was substantially greater and lasted much longer during fixation through the pinhole. It is hypothesized that this increase in accommodation is a result of a vestibular-ocular accommodation reflex.

    Glaucomatous neuropathy can be a consequence of insufficient blood supply, increase in intraocular pressure (IOP), or other risk factors that diminish the ocular blood flow. To determine the ocular perfusion pressure (OPP) in normal and systemic hypertensive patients. One hundred and twenty-one patients were enrolled in this prospective and comparative study and underwent a complete ophthalmologic examination including slit lamp examination, Goldmann applanation tonometry, stereoscopic fundus examination, and pulsatile ocular blood flow (POBF) measurements. The OPP was calculated as being the medium systemic arterial pressure (MAP) less the IOP. Only right eye values were considered for calculations using Student's t-test. The mean age of the patients was 57.5 years (36-78), and 68.5% were women. There was a statistically significant difference in the OPP of the normal and systemic hypertensive patients (p cite this article: Kanadani FN, Figueiredo CR, Miranda RM, Cunha PLT, Kanadani TCM, Dorairaj S.

    Full Text Available Toxoplasma gondii is a protozoan parasite that infects up to a third of the world′s population. Infection is mainly acquired by ingestion of food that is contaminated with oocysts. We report an outbreak of ocular toxoplasmosis, which is an acute acquired type rather than reactivation of congenital toxoplasmosis. Our preliminary investigation points to municipal water contamination. This outbreak only proves the need of an effective public health system and health education in curtailing any outbreak.

    Injection drug use can result in a variety of severe ocular conditions. Hematogenous dissemination of various fungi and bacteria may produce endophthalmitis with resultant severe visual loss. Retinal arterial occlusive disease may result from talc and other particulate emboli. Most commonly, life-threatening systemic diseases such as endocarditis and HIV infection secondarily affect the eye. Because many of these conditions may result in blindness if untreated, accurate diagnosis and prompt initiation of therapy are essential.

    2015-02-01

    This review is intended to summarize the current knowledge from basic science and clinical medical literature cited within PubMed that pertain to gender-related factors and affect those individuals with hereditary ocular disorders. We consider gender-related biological factors that (a) affect disease onset and progression, (b) gender differences for major X-linked ocular disorders, (c) gender-specific conditions, (d) medications that may influence genetic eye disorders, and finally, (e) gender-related issues that influence the management and quality of life of these patients. Several studies have demonstrated the manner in which sex-related hormones in animal models are capable of influencing cell pathway and survival that are likely to affect hereditary eye disorders. There are very few clinical studies that provide compelling evidence for gender differences in human ocular conditions, other than for a number of X-linked disorders. Disease expression for X-linked disorders may be impacted by genetic mechanisms such as lyonization or uniparental disomy. Clinical evidence regarding the impact of gender-related medical conditions and therapies on eye conditions is extremely limited and primarily based on anecdotal evidence. Gender-specific factors may play a major role in the underlying biological pathways that influence the onset, rate of progression, and clinical findings associated with ocular genetic conditions. Clinicians need to be aware of the variable phenotypes observed in female carriers of X-linked disorders of gender specific issues, many of which are inadequately addressed in the current literature. Clinicians need to be sensitive to gender differences in social, cultural, and religious systems and they should also be aware of how their own gender biases may influence how they counsel patients. Finally, it is clear that the lack of effective clinical studies in this area creates an opportunity for future research that will have real benefits for these

  17. Experimental models of autoimmune inflammatory ocular diseases

    Full Text Available Ocular inflammation is one of the leading causes of blindness and loss of vision. Human uveitis is a complex and heterogeneous group of diseases characterized by inflammation of intraocular tissues. The eye may be the only organ involved, or uveitis may be part of a systemic disease. A significant number of cases are of unknown etiology and are labeled idiopathic. Animal models have been developed to the study of the physiopathogenesis of autoimmune uveitis due to the difficulty in obtaining human eye inflamed tissues for experiments. Most of those models are induced by injection of specific photoreceptors proteins (e.g., S-antigen, interphotoreceptor retinoid-binding protein, rhodopsin, recoverin, phosducin. Non-retinal antigens, including melanin-associated proteins and myelin basic protein, are also good inducers of uveitis in animals. Understanding the basic mechanisms and pathogenesis of autoimmune ocular diseases are essential for the development of new treatment approaches and therapeutic agents. The present review describes the main experimental models of autoimmune ocular inflammatory diseases.

    Full Text Available La miastenia grave es una enfermedad caracterizada por debilidad y fatiga de los músculos voluntarios debido a una trasmisión anómala a nivel de la unión neuromuscular. La prevalencia es aproximadamente de 5 casos/100 000 personas. La miastenia grave puede ser bulbar, ocular o generalizada.Existen formas clínicas en la infancia como son la miastenia neonatal transitoria, la miastenia congénita y la miastenia juvenil. Los músculos oculares, faciales y bulbares son los más frecuentes afectados por la enfermedad. Cuando los síntomas se limitan a la musculatura cercana al ojo se denomina miastenia grave ocular. Una vez el oftalmólogo diagnostica o sospecha la miastenia grave, un neurólogo generalmente dirige la comprobación y tratamiento. El papel del oftalmólogo continúa siendo importante, además de chequear la motilidad y disfunción palpebral y proporcionar el alivio sintomático para estos desórdenes, debe estar alerta a la posibilidad de ambliopía.

    The choroidal osteoma is a benign bony tumor described for the first time in 1978 by Gass and collaborators. It is generally unilateral, with juxtapapillary localization and more frequent in young adult females. It presents unknown etiology, but it is associated to different factors as inflammatory processes, congenital malformations, hormonal alterations and ocular traumas among others. The patient was a 54 year-old woman with a personal history of rheumatic fibromyalgia (osteoarthrosis and osteoporosis) and hypertension. Her ophthalmological antecedent showed myopia and arteriolosclerotic retinopathy. At the beginning of the year, she suffered a traffic accident and was injured in her limbs and periocular region. After this, she began feeling blurred vision of the right eye and she went to our service 6 months later. She was performed an ophthalmologic exam. It was found that the right eye had visual acuity of 0.4, and after correction it reached 1.0. Funduscopy revealed vascular thinness, incomplete posterior vitreous detachment, and a white-orange lesion of 3 papillary diameters that involved inferior temporary arcade with well-defined borders. An angiography was performed, which showed sustained hyperfluorescence and non neovascularization; and the optic coherence tomography revealed a halo of serous retinal detachment. Additionally, the ocular ultrasound yielded a high reflectivity echogenic image that involves choroids with posterior acoustic shadow. It is for this reason that we affirm the traumatic etiology of the lesion. This is a rare pathology that should be diagnosed by imaging techniques. Notably, it is secondary to an ocular trauma

    Ophthalmic liposomes of ganciclovir (GCV) were prepared by the reverse phase evaporation method, and their ocular pharmacokinetics in albino rabbits were compared with those obtained after dosing with GCV solution. The in vitro transcorneal permeability of GCV liposomes was found to be 3.9-fold higher than that of the solution. After in vivo instillation in albino rabbits, no difference was found in the precorneal elimination rate of GCV from liposome vs solution dosing. The aqueous humor concentration-time profiles of both liposomes and solution were well described by 2-compartmental pharmacokinetics with first-order absorption. The area under the curve of the aqueous humor concentration-time profiles of GCV liposomes was found to be 1.7-fold higher than that of GCV solution. Ocular tissue distribution of GCV from liposomes was 2 to 10 times higher in the sclera, cornea, iris, lens, and vitreous humor when compared with those observed after solution dosing. These results suggested that liposomes may hold some promise in ocular GCV delivery.

    To describe the pattern of ocular surface squamous neoplasia (OSSN), clinical presentations, the risk factors and treatment options. The study included 36 eyes of 35 patients with biopsy-proven ocular surface neoplasia. The details of patients regarding age, gender, laterality and risk factors were entered into a specially-designed proforma. Each patient was also assessed biomicroscopically for type and complications of ocular surface neoplasia. The frequency of OSSN was 0.37 among admitted hospital patients. Among 36 cases of OSSN, squamous cell carcinoma of the conjunctiva was the most common type of OSSN seen in 63.9%, followed by carcinoma in situ of conjunctiva in 25% and carcinoma in situ of cornea in 11.1%. Male patients outnumbered female (65.7% vs 34.3%) with 71.42% of patients above 60 years of age. The risk factors identified were: old age, ultraviolet B exposure and xeroderma pigmentosa. Treatment consisted of local resection with or without adjuvant therapy in 61.1%, exenteration in 30.5%, enucleation in 5.5% and chemo/radiotherapy in 2.7%. Intraocular invasion was seen in 5.5% and orbital spread in 30.5%. The frequency of OSSN was 0.37% among admitted patients. Identification of exact etiological factors will enable to formulate strategies that are likely to decrease the incidence of this disease and the associated morbidity and mortality. (author)

    2017-10-19

    71-year-old woman with progressive left-sided, monocular diplopia and ptosis. Her symptoms mimicked ocular myasthenia, but she had an indirect carotid cavernous fistula (CCF). She was diagnosed with monocular myasthenia gravis (negative acetylcholinesterase antibody) after a positive ice test and started on Mestinon and underwent a thymectomy complicated by a brachial plexus injury. Months later, she developed left-sided proptosis and ocular bruit. She was urgently referred to neuro-interventional surgery and was diagnosed with an indirect high-flow left CCF, which was treated with Onyx liquid and platinum coil embolisation. Mestinon was discontinued. Her ophthalmic symptoms resolved. However, she was left with a residual left arm and hand hemiparesis and dysmetria secondary to a brachial plexus injury. Indirect CCF usually can present with subtle and progressive symptoms leading to delayed diagnosis or misdiagnosis. It is important for ophthalmologists to consider this differential in a patient with progressive ocular symptoms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Full Text Available Purpose: To evaluate the demography, aetiology, type and outcome of paediatric ocular trauma in tertiary centre in Malaysia. Method: We retrospectively studied 118 eyes from 117 patients over a period of 36 months (January 2006 to December 2008. All ocular injuries in patients aged 12 and below seen in the Ophthalmology Department for the first time were included in thisstudy. Results: Mean age of patients was 6.1±3.0 years. 68 cases (58.2% occurred in pre-school children, whereas 49 (41.9% in school-aged children. Boys accounted for 65.8% of cases. There was no predilection for either right or the left eye. 47% of cases (56 patients occurred in Malay. Most of the injuries took place at home when the children were alone (p<0.05. Sharp objects were the commonest cause (45 cases, 38.1%. The majority of cases (103, 87.3% were considered preventable. The frequency of open and closed globe injury was similar. Hyphema was more common in closed globe injury compared to open globe injury (p<0.05. Other associated injuries such as cataract, vitreous hemorrhage and retinal hemorrhage are similar between the two groups. Visual outcome is generally poor with only 34 eyes (28.8% had no visual impairment. Conclusion: Ocular trauma in children is an important cause of visual loss. Most cases occurred at home and were preventable. Prevention through education is the best approach.

    Full Text Available Normal tension glaucoma (NTG is known as a multifactorial optic neuropathy characterized by progressive retinal ganglion cell death and glaucomatous visual field loss, even though the intraocular pressure (IOP does not exceed the normal range. The pathophysiology of NTG remains largely undetermined. It is hypothesized that the abnormal ocular blood flow is involved in the pathogenesis of this disease. A number of evidences suggested that the vascular factors played a significant role in the development of NTG. In recent years, the new imaging techniques, fluorescein angiography, color Doppler imaging (CDI, magnetic resonance imaging (MRI, and laser speckle flowgraphy (LSFG, have been used to evaluate the ocular blood flow and blood vessels, and the impaired vascular autoregulation was found in patients with NTG. Previous studies showed that NTG was associated with a variety of systemic diseases, including migraine, Alzheimer’s disease, primary vascular dysregulation, and Flammer syndrome. The vascular factors were involved in these diseases. The mechanisms underlying the abnormal ocular blood flow in NTG are still not clear, but the risk factors for glaucomatous optic neuropathy likely included oxidative stress, vasospasm, and endothelial dysfunction.

  5. Vitamin D in ocular and systemic health

    Vitamin D is produced in skin exposed to sunlight UVB radiation and is then metabolised by the kidney into calciferol, which is an active form. The main function of vitamin D is to promote calcium and phosphorus absorption, and studies have shown that a lack of itplays an important role in ocular conditions, such as age-related macular degeneration and diabetic retinopathy. Recent studies have suggested that vitamin D may protect the diabetic retina; however, other vitamin D-associated conditions (diabetes, hypertension and cardiovascular diseases may result in secondary ocular manifestations and the potential forsight-threatening complications. The purpose of this review is to describe the current literature on the role of vitamin D in ocular and systemic wellness. However, more research is needed to determine if increasing levels of this vitamin can assist in preventing age-related macular degeneration or diabetic retinopathy. Since vitamin D is a circulating steroid hormone, its receptors are found in almost every cell in the human body, and this suggests that vitamin D might have a very broad role for overall health. However, there is still demand for further research to clarify the clinical use of vitamin D in the prevention and treatment of various chronic diseases.

    Full Text Available O presente artigo enfoca a perspectiva dos professores de um curso livre que tem como um dos princípios o uso exclusivo da língua-alvo. A partir de uma fundamentação teórica que discute o papel da L1 em diferentes tipos de métodos e abordagens de ensino, que têm por base diferentes teorias de aquisição de linguagem, foi possível discutir sobre as motivações, vantagens e desvantagens do uso da L1 apontadas pelos professores, bem como a coerência entre tais fatores e o que acontece em sala de aula, em suas práticas de ensino. Questionários escritos e gravações de áudio das aulas dos professores constituíram os instrumentos para a coleta dos dados. Por meio deste estudo, foi possível constatar que não somente o bom senso dos professores com relação ao uso exclusivo da língua-alvo é fundamental, mas também que não é possível classificar a prática dos profissionais sob uma única concepção de aquisição de linguagem, ao ser considerada a relação entre teoria e prática dos professores

    Full Text Available Este artigo discute o cuidado na relação entre professoras, professores e estudantes, problematizando, a partir de autoras da teoria feminista, que a socialização de cidadãos conscientes de seus direitos e deveres deva ser a finalidade principal da educação. Nas relações de cuidado se evidenciam a interdependência e a mutualidade - afetiva e cognitiva -, aspectos esses que perpassam as relações entre educadores e alunos na escola. As condições atuais de desvalorização da carreira docente e sua burocratização têm conduzido a uma objetificação das relações na escola, resultando em vínculos baseados na tutela e na disciplinarização, em detrimento do cuidado. Por fim, discutimos a potencialidade política do cuidado, ao permitir que professoras, professores e alunos se vejam como mutuamente dependentes. Entendemos que a ação política pode surgir da condição de dependência e do sentimento de responsabilização que se produzem a partir de experiências domésticas e familiares, e não em detrimento das mesmas.

    Dry eye can damage the ocular surface and result in mild corneal epithelial defect to blinding corneal pannus formation and squamous metaplasia. Significant progress in the treatment of dry eye has been made in the last two decades; progressing from lubricating and hydrating the ocular surface with artificial tear to stimulating tear secretion; anti-inflammation and immune regulation. With the increase in knowledge regarding the pathophysiology of dry eye, we propose in this review the concept of ocular surface microenvironment. Various components of the microenvironment contribute to the homeostasis of ocular surface. Compromise in one or more components can result in homeostasis disruption of ocular surface leading to dry eye disease. Complete evaluation of the microenvironment component changes in dry eye patients will not only lead to appropriate diagnosis, but also guide in timely and effective clinical management. Successful treatment of dry eye should be aimed to restore the homeostasis of the ocular surface microenvironment.

    Teamwork is increasingly seen as an important component of engineering education programmes. Yet, prior research has shown that there are numerous ways in which teamwork is gendered, and can lead to negative experiences for women students. This article presents the first interview findings on professors' perspectives on gender and teamwork. Semi-structured interviews were conducted with 39 engineering professors to determine what and how they thought about gender in engineering and engineering education. For this article, the parts of the interviews about teamwork are analysed. We conclude that professors need tools to help them facilitate gender-inclusive teamwork, and those tools must address the beliefs that they already hold about teamwork. The findings raise questions about the adoption of evidence-based instructional practices and suggest current teamwork practices may exacerbate gender inequalities in engineering.

    Professor Kazimierz Jaegermann, a founder of the theory of medico-legal opinionating, passed away 20 years ago. Numerous specialists in forensic medicine and an ever increasing number of lawyers substantiate the importance and value of the creative thought and the entire research work of Professor Jaegermann that have been an inspiration of progress in forensic medicine and in the science of applied law. His unique ability to perform a scientific synthesis leading to recognizing forensic medicine as an applied bridging knowledge points to the eminently creative role played by Professor Jaegermann in development of forensic medicine. There is an urgent need to recall his research activities and to publish a complete collection of his articles and publications. With this idea in mind, I present below an article based on the text published in No. 1 of the Zeszyty Naukowe Katedry Medycyny Sadowej Slaskiej Akademii Medycznej in 1995.

    Full Text Available Aim/Purpose: In the United States, faculty who wish to pursue promotion to the rank of professor do so without clear guidance or structure. Even the timing of such a process is nebulous. As such, an individual engages in agentic action to pursue the rank. Background: This study examined the experiences of faculty members who chose to pursue the application process to be promoted to professor but were rejected or dissuaded. Methodology: Utilizing a case study of one institutional setting, we conducted 10 in-depth qualitative interviews. Contribution: Very little is known about the process of promotion to full professor in the U.S. and even less empirical research exists. This study advances knowledge of the process and the experiences of those undertaking it. Findings: We learned that cues from the social context greatly influenced these faculty members’ sense of agency.

    Full Text Available RESUMO: Desmama é uma fase crítica na vida do suíno devido a separação materna e a introdução de uma dieta seca. A termografia infravermelha medida na região ocular se mostra como um indicador confiável para a condição de estresse pontual de suínos. O objetivo deste estudo foi determinar a relação entre medidas de termografia infravermelha da superfície ocular e de cortisol em situações de estresse em leitões na pós desmama. Foram avaliados 66 leitões, uma vez por semana, durante sete semanas, em dois períodos do dia (7h e 15h com medidas de temperatura superficial ocular, temperatura superficial do dorso e amostras de saliva para determinação de cortisol salivar. A análise estatística contemplou os efeitos fixos de semana e período do dia e sua interação e correlações de Pearson para relação entre termografia ocular, temperatura superficial e cortisol a 5% de significância. Cortisol salivar não diferiu entre os períodos, mas foi superior nas três primeiras semanas após o desmame (P<0,05. Nas duas primeiras semanas após a desmama o cortisol apresentou correlação alta e positiva (P<0,05 com a temperatura ocular máxima (0,89 e a temperatura superficial do dorso (0,80. As duas temperaturas superficiais apresentaram uma associação moderada positiva (r=0,41; P<0,0001 durante todo o período experimental. Este estudo destaca que a temperatura de superfície ocular obtida por meio da termografia infravermelha pode ser um indicador de temperatura de superfície corporal e estado de bem-estar de leitões em fase de creche, além de ser um método não invasivo e de rápida mensuração. Entretanto, mais pesquisas são necessárias para aprofundar a relação entre temperatura ocular e cortisol durante estresse crônico.

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

    2014-01-01

    Background Since there has been no conclusive evidence regarding the treatment of ocular myasthenia, treatment guidelines were recently issued by the European Federation of Neurological Societies/European Neurological Society (EFNS/ENS). However, the therapeutic outcomes concerning the quality-of-life (QOL) of patients with ocular myasthenia are not yet fully understood. Methods We investigated the therapeutic outcomes of patients with purely ocular myasthenia in a multicenter cross-sectional survey in Japan. To evaluate the severity of ocular symptoms, we used the ocular-quantitative MG (QMG) score advocated by Myasthenia Gravis Foundation of America. We used the Japanese translated version of the MG-QOL15, a self-appraised scoring system. Results Of 607 myasthenia gravis (MG) patients with an observation-duration of illness ≥ 2 years, the cases of 123 patients (20%) were limited to ocular muscles (purely ocular myasthenia). During the entire clinical course, 81 patients experienced both ptosis and diplopia, 36 had ptosis alone, and six had diplopia alone. Acetyl-cholinesterase inhibitors and prednisolone were used in 98 and 52 patients, respectively. Treatment improved ocular symptoms, with the mean reduction in ocular-QMG score of 2.3 ± 1.8 points. However, 47 patients (38%) failed to gain minimal manifestation or a better status. Patients with unfavorable outcomes also self-reported severe QOL impairment. Multivariate analyses showed that the pretreatment ocular-QMG score was associated with unfavorable outcomes, but not associated with the patient’s QOL. Conclusion A treatment strategy designed in accord with a patient's ocular presentation must be considered in order to improve ocular symptoms and the patient's QOL. PMID:24996227

    2015-01-01

    Background Two important influences on students' evaluations of teaching are relationship and professor effects. Relationship effects reflect unique matches between students and professors such that some professors are unusually effective for some students, but not for others. Professor effects reflect inter-rater agreement that some professors are more effective than others, on average across students. Aims We attempted to forecast students' evaluations of live lectures from brief, video-recorded teaching trailers. Sample Participants were 145 college students (74% female) enrolled in introductory psychology courses at a public university in the Great Lakes region of the United States. Methods Students viewed trailers early in the semester and attended live lectures months later. Because subgroups of students viewed the same professors, statistical analyses could isolate professor and relationship effects. Results Evaluations were influenced strongly by relationship and professor effects, and students' evaluations of live lectures could be forecasted from students' evaluations of teaching trailers. That is, we could forecast the individual students who would respond unusually well to a specific professor (relationship effects). We could also forecast which professors elicited better evaluations in live lectures, on average across students (professor effects). Professors who elicited unusually good evaluations in some students also elicited better memory for lectures in those students. Conclusions It appears possible to forecast relationship and professor effects on teaching evaluations by presenting brief teaching trailers to students. Thus, it might be possible to develop online recommender systems to help match students and professors so that unusually effective teaching emerges. PMID:24953773

    1992-01-01

    The eye movement response to earth vertical axis rotation in the dark, a semicircular canal stimulus, can be altered by prior exposure to combined visual-vestibular stimuli. Such plasticity of the vestibulo-ocular reflex has not been described for earth horizontal axis rotation, a dynamic otolith stimulus. Twenty normal human subjects underwent one of two types of adaptation paradigms designed either to attenuate or enhance the gain of the semicircular canal-ocular reflex prior to undergoing otolith-ocular reflex testing with horizontal axis rotation. The adaptation paradigm paired a 0.2 Hz sinusoidal rotation about a vertical axis with a 0.2 Hz optokinetic stripe pattern that was deliberately mismatched in peak velocity. Pre- and post-adaptation horizontal axis rotations were at 60 degrees/s in the dark and produced a modulation in the slow component velocity of nystagmus having a frequency of 0.17 Hz due to putative stimulation of the otolith organs. Results showed that the magnitude of this modulation component response was altered in a manner similar to the alteration in semicircular canal-ocular responses. These results suggest that physiologic alteration of the vestibulo-ocular reflex using deliberately mismatched visual and semicircular canal stimuli induces changes in both canal-ocular and otolith-ocular responses. We postulate, therefore, that central nervous system pathways responsible for controlling the gains of canal-ocular and otolith-ocular reflexes are shared.

    The purpose of this report is to summarize an understanding of the ocular motor system in patients with albinism. Other than the association of vertical eccentric gaze null positions and asymmetric, (a) periodic alternating nystagmus in a large percentage of patients, the ocular motor system in human albinism does not contain unique pathology, rather has "typical" types of infantile ocular oscillations and binocular disorders. Both the ocular motor and afferent visual system are affected to varying degrees in patients with albinism, thus, combined treatment of both systems will maximize visual function.

    Smartphone use has dramatically increased in recent years. Smartphones may have adverse health effects, particularly on the eyes, because users stare at the screen for a much longer time than they do with ordinary mobile phones. The objective of this study was to elucidate the relationship between smartphone use and ocular symptoms among adolescents. Information on smartphone use and ocular symptoms (blurring, redness, visual disturbance, secretion, inflammation, lacrimation and dryness) related to eye fatigue and strain from 715 adolescent subjects from three cities in Korea was obtained using a structured questionnaire. Ocular health was scored using number of ocular symptoms. Odds ratios (ORs), 95% confidence intervals (95% CIs) and p-values for ocular symptoms were calculated with binomial and multinomial logistic regression models. Higher prevalence rates for ocular symptoms were observed in groups with greater exposure to smartphones (p 2 hours daily and ≤2 hours continuously) and excessive/persistent use (>2 hours daily and >2 hours continuously) compared to shorter use (<2 hours daily) were associated with multiple ocular symptoms (OR 2.18, 95% CI 1.09-4.39; OR 2.26, 95% CI 1.11-4.57, respectively). A higher lifetime exposure to smartphones was associated with a higher likelihood of having multiple ocular symptoms (OR 3.05, 95% CI 1.51-6.19; p = 0.001). Increasing exposure to smartphones can have a negative impact on ocular health in adolescents.

    Full Text Available The aim of this manuscript is to review the action and adverse effects of combined oral contraceptives (COCs on ocular tissues. The percentage of unwanted pregnancies and the subsequent abortions make contraception crucial worldwide. Over 100 million women around the world use common contraceptive methods, including intrauterine devices, combined estrogen and progestin oral contraceptives, as well as progestin only preparations (oral contraceptives, implants or injections. COCs are widely used for contraception, but they are also indicated in menorrhagia, endometriosis, acne and hirsutism, fibroid uterus and premenstrual syndrome. However, they have been associated with high rates of cardiovascular events, venous thromboembolic disease, ischemic strokes and breast cancer. The incidence of COCs-related ocular complications is estimated to be 1 in 230 000, including dry eye symptoms, corneal edema, lens opacities and retinal neuro-ophthalmologic or vascular complications. We may infer that the serious ocular complications of COCs can be prevented by eliminating the estrogen dosage and choosing third-generation progestins. In any case, doctors should take into consideration the systemic and ocular history of the patients before selecting any method of contraception.

    Full Text Available Background - Ocular surface disorders due to limbal stem cell deficiency are an important cause of ocular morbidity and visual loss. Although autologous limbal stem cell transplants have helped in the management of unilateral disease, allografts in those with bilateral disease often fail due to immunological reasons. The use of autologous buccal epithelium cultivated on amniotic membrane has been described as a useful approach in the management of this condition. It is the purpose of this study to explore the feasibility of using a novel thermo-gelatin polymer (TGP as a substrate to culture these cells, and to characterize them using RNA extraction and RT-PCR. Methods - Oral cheek mucosal biopsies were obtained from 5 adult patients undergoing Modified Osteo-Odonto Keratoprosthesis surgery. The specimens were transported to the laboratory in transport medium. The cells were released using enzymatic digestion and seeded in both convention culture medium and TGP. The resulting cellular growth was characterized using RNA extraction and RT-PCR. Results - Cells could be cultured from 4 of the 5 specimens. In one specimen, contamination occurred and this was discarded. In the other specimens, the cheek epithelial cells could be cultured in both the conventional culture medium and TGP, with equal ease. RT-PCR revealed the presence of K3, a marker for epithelial cells, and GAPDH indicating the presence of some adipose tissue as well. Conclusions - It is possible to culture autologous cheek mucosal epithelial cells using TGP, a synthetic scaffold, without the need for other biological substrates. Since the specimens are obtained from the oral cavity, stringent asepsis is required. Further studies are required for histopathological characterization of the cultured cells and to create a model for delivery onto the ocular surface of eyes with bilateral surface disease due to limbal stem cell deficiency.

    Full Text Available BACKGROUND Worldwide, ocular trauma is an important cause of eye morbidity and a leading cause of non-congenital monocular blindness among children. In general, children are more susceptible to eye injuries because of their immature motor skills, limited common sense, tendency to imitate adult behaviour without evaluating risks, lessened emotional control, relative ignorance, and natural curiosity. Adult supervision is extremely important in preventing accidents. 1 PATIENTS AND METHODS The material for this study consisted of paediatric patients below 15 years of age who presented with history of different types of ocular injuries during the period from March 2007 to February 2010. In all cases, a thorough history was obtained from patients and their parents regarding the circumstances leading to the injury, the exact nature of the event and the object causing the injury. All the patients were also subjected to complete ophthalmic examination and followed up for 6 months. RESULTS 34 (68% were males and 16 (32% were females. The average age was 10.9 years (range 1-15 years. The highest incidence of blunt injuries was seen in age group of 11-15 years (58%. 20 (40% injuries occurred during domestic and leisure activities, 7(14% injuries occurred at work, 13 (26% during sports, 6 (12% were due to assault and 4 (8% from RTAs. CONCLUSION Blunt trauma to the eye causes a wide variety of damage to ocular tissues. Anterior or posterior segments are preferentially involved. Males were observed to be at increased risk for an eye injury necessitating admission to hospital.

    To determine which biometric parameters provide optimum predictive power for ocular volume. Sixty-seven adult subjects were scanned with a Siemens 3-T MRI scanner. Mean spherical error (MSE) (D) was measured with a Shin-Nippon autorefractor and a Zeiss IOLMaster used to measure (mm) axial length (AL), anterior chamber depth (ACD) and corneal radius (CR). Total ocular volume (TOV) was calculated from T2-weighted MRIs (voxel size 1.0 mm(3)) using an automatic voxel counting and shading algorithm. Each MR slice was subsequently edited manually in the axial, sagittal and coronal plane, the latter enabling location of the posterior pole of the crystalline lens and partitioning of TOV into anterior (AV) and posterior volume (PV) regions. Mean values (±SD) for MSE (D), AL (mm), ACD (mm) and CR (mm) were -2.62±3.83, 24.51±1.47, 3.55±0.34 and 7.75±0.28, respectively. Mean values (±SD) for TOV, AV and PV (mm(3)) were 8168.21±1141.86, 1099.40±139.24 and 7068.82±1134.05, respectively. TOV showed significant correlation with MSE, AL, PV (all p<0.001), CR (p=0.043) and ACD (p=0.024). Bar CR, the correlations were shown to be wholly attributable to variation in PV. Multiple linear regression indicated that the combination of AL and CR provided optimum R(2) values of 79.4% for TOV. Clinically useful estimations of ocular volume can be obtained from measurement of AL and CR. Published by the BMJ Publishing Group Limited.

    1999-01-01

    To date, sildenafil citrate (Viagra) gives every evidence of being a safe drug for the eye despite a series of expressed concerns. A review of how its ocular safety profile has been identified offers insights into the strengths and weaknesses of present systems and resources for judging the ocular safety of Viagra or, for that matter, of any new drug. Such insights include: The great value of careful, informed assessment of preclinical information gleaned from laboratory experiments. By and large, such assessments point the way toward appropriate clinical evaluation. For Viagra, early in its development it was noted that besides exerting a major inhibitory effect on the intended target, the vascular-associated enzyme phosphodiesterase 5 (PDE5), the drug also exerts a lesser but definite inhibitory effect on the closely related PDE6, located in the retina. For this reason, preclinical evaluation of the drug included electroretinography plus postmortem histology. In addition, an extended eye examination was incorporated into clinical protocols. The often chaotic but invaluable information stream that becomes available once marketing approval has been gained and large populations begin to use a drug. False alarms, misattribution, and erroneous information are the order of the day. Nevertheless, as information accumulates, patterns of response clarify and the true nature of special susceptibility for subpopulations, if any, becomes apparent. A role for the astute clinician remains: Subtle changes or unusual risks for subpopulations can be missed entirely for long periods of time. A manifest need for improvement in evaluation of postmarketing side-effects. This need has led to the establishment of a new discipline: pharmacoepidemiology. In ophthalmology, the National Registry of Drug Induced Ocular Side-Effects maintains a constant and invaluable surveillance. Examples are supplied to illustrate each of these major points: Our presentation will include data gleaned from

  1. Silk film biomaterials for ocular surface repair

    Lawrence, Brian David

    Current biomaterial approaches for repairing the cornea's ocular surface upon injury are partially effective due to inherent material limitations. As a result there is a need to expand the biomaterial options available for use in the eye, which in turn will help to expand new clinical innovations and technology development. The studies illustrated here are a collection of work to further characterize silk film biomaterials for use on the ocular surface. Silk films were produced from regenerated fibroin protein solution derived from the Bombyx mori silkworm cocoon. Methods of silk film processing and production were developed to produce consistent biomaterials for in vitro and in vivo evaluation. A wide range of experiments was undertaken that spanned from in vitro silk film material characterization to in vivo evaluation. It was found that a variety of silk film properties could be controlled through a water-annealing process. Silk films were then generated that could be use in vitro to produce stratified corneal epithelial cell sheets comparable to tissue grown on the clinical standard substrate of amniotic membrane. This understanding was translated to produce a silk film design that enhanced corneal healing in vivo on a rabbit injury model. Further work produced silk films with varying surface topographies that were used as a simplified analog to the corneal basement membrane surface in vitro. These studies demonstrated that silk film surface topography is capable of directing corneal epithelial cell attachment, growth, and migration response. Most notably epithelial tissue development was controllably directed by the presence of the silk surface topography through increasing cell sheet migration efficiency at the individual cellular level. Taken together, the presented findings represent a comprehensive characterization of silk film biomaterials for use in ocular surface reconstruction, and indicate their utility as a potential material choice in the

    Full Text Available Objectives: To investigate the frequency of angle recession, commotio retinae, and other ocular findings in patients with hyphema due to blunt ocular trauma. Materials and Methods: The medical records of 66 patients hospitalized between July 2010 and May 2012 with a diagnosis of traumatic hyphema were retrospectively reviewed. The age, gender, period between injury and the first examination, visual acuity at presentation, intraocular pressure (IOP, time of disappearance of hyphema, cause of blunt injury, additional ocular findings, medical and/or surgical treatment, follow-up time, and visual outcome were noted. Results: The mean age of the patients was 23.8±19.2 years. Males constituted the 83.3% of the whole group. Game-related injury (43.9% and work-related injury (22.7% were the most common causes of blunt trauma. The bead gun was the most common tool involved in injury. Angle recession was detected in 36 patients (54.5%. Development of secondary glaucoma was higher in the patients with angle recession (chi-square test, p<0.05. Commotio retinae was observed in 47% of patients. The mean visual acuity at presentation was 0.4±0.3, while at the last visit, it was 0.8±0.3. There was a statistically significant difference between baseline and final visual acuity (paired-samples t-test, p<0.001. Conclusion: Hyphema due to blunt ocular trauma is observed mostly in young men and children. The most common blunt ocular injuries are game-and work-related. Angle recession and commotio retinae are the main complications of blunt ocular trauma causing hyphema. In cases with blunt ocular trauma, the presence of hyphema makes it difficult to examine the anterior chamber angle and the fundus. It is important to perform these investigations at the earliest stage to manage the complications since commotio retinae and angle recession accompany many cases with hyphema.

    Lidocaine hydrochloride ophthalmic gel is a novel ophthalmic preparation for topical ocular anesthesia. The study is aimed at evaluating the ocular and systemic pharmacokinetics of lidocaine hydrochloride 3.5 % ophthalmic gel in rabbits after ocular topical administration. Thirty-six rabbits were randomly placed in 12 groups (3 rabbits per group). The rabbits were quickly killed according to their groups at 0 (predose), 0.0833, 0.167, 0.333, 0.667, 1, 1.5, 2, 3, 4, 6, and 8 h postdose and then the ocular tissue and plasma samples were collected. All the samples were analyzed by a validated LC-MS/MS method. The test result showed that the maximum concentration (C max) of lidocaine in different ocular tissues and plasma were all achieved within 20 min after drug administration, and the data of C max were (2,987 ± 1814) μg/g, (44.67 ± 12.91) μg/g, (26.26 ± 7.19) μg/g, (11,046 ± 2,734) ng/mL, and (160.3 ± 61.0) ng/mL for tear fluid, cornea, conjunctiva, aqueous humor, and plasma, respectively. The data of the elimination half-life in these tissues were 1.5, 3.2, 3.5, 1.9, and 1.7 h for tear fluid, cornea, conjunctiva, aqueous humor, and plasma, respectively. The intraocular lidocaine levels were significantly higher than that in plasma, and the elimination half-life of lidocaine in cornea, conjunctiva, and aqueous humor was relatively longer than that in tear fluid and plasma. The high intraocular penetration, low systemic exposure, and long duration in the ocular tissues suggested lidocaine hydrochloride 3.5 % ophthalmic gel as an effective local anesthetic for ocular anesthesia during ophthalmic procedures.

    Objective: To study the pathological and clinical characteristics of primary lymphoma of ocular adnexae, analyze the treatment results and discuss the methods to prevent radiation complications. Methods: From Feb. 1995 to Feb. 2004, 25 patients with primary ocular adnexal lymphoma were treated in the second hospital and the forth hospital of Xuzhou, including 11 males and 14 females. The diagnosis was confirmed pathologically by biopsy in 19 patients and lumpectomy in 6 patients, including 22 mucosa-associated lymphoid tissue (MALT) lymphoma and 3 non-MALT lymphoma. According to the Ann Arbor Staging System, there were 21 patients with tumor in stage I E, 3 in stage II E and 1 in stage III E. The primary tumor was found in the eyelid or conjunctiva in 19 eyes and orbit in 9 eyes. Radiotherapy were given to 22 patients (25 eyes) by deep X-rays, 60 Co γ-rays or mixed beams. The total irradiation dose ranged from 30.0 to 57.6 Gy. Kaplan-Meier method was used to calculate the survival rate and Logrank test was used to detect the difference between the different groups. Results: The 5-, 10-year accumulated survival rates (SR) of the whole group were 90% and 82%. The 10-year SR of patients with primary, eyelid or conjunctiva tumor and orbit tumor were 100% and 58% (P=0.032). The local control rates of the radiotherapy group and non-radiotherapy group were 92% and 33 % (P=0.006). The 10-year SR of patients with tumor completely removed and those with residues were 83% and 82% (P=0.907). The 10-year SR of MALT lymphoma and non-MALT lymphoma were 90.0% and 33.3% (P=0.009). After radiotherapy, 8 eyes (36%) had cataract formation and 7 eyes (28%) had xerophalmic symptoms. Conclusions: The results of radiothera- py for the primary ocular adnexal lymphoma are satisactory. The prognosis of patients with primary, eyelid or conjunctiva tumor is better than those with orbit tumor. The vast majority of the primary ocular adnexal lymphomas are MALT lymphomas.

    Ocular infection caused by Toxoplasma gondii, a parasite, may result in inflammation in the retina, choroid, and uvea, and consequently lead to complications such as glaucoma, cataract, and posterior synechiae. The objective of this systematic review was to assess the effects of adjunctive use of corticosteroids to anti-parasitic therapy versus anti-parasitic therapy alone for ocular toxoplasmosis. We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register (2016; Issue 11)), MEDLINE Ovid, Epub Ahead of Print, In-Process & Other Non-Indexed Citations, MEDLINE Ovid Daily (January 1946 to December 2016), Embase (January 1980 to December 2016), Latin American and Caribbean Literature on Health Sciences (LILACS (January 1982 to December 2016)), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP; www.who.int/ictrp/search/en). We used no date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 7 December 2016. We had planned to include randomized and quasi-randomized controlled trials. Eligible trials would have enrolled participants of any age who were immunocompetent and were diagnosed with acute ocular toxoplasmosis. Included trials would have compared anti-parasitic therapy plus corticosteroids versus anti-parasitic therapy alone, different doses or times of initiation of corticosteroids. Two authors independently screened titles and abstracts retrieved through the electronic searches. We retrieved full-text reports of studies categorized as 'unsure' or 'include' after we reviewed the abstracts. Two authors independently reviewed each full-text report for eligibility. Discrepancies were resolved through discussion. We identified no completed or ongoing trial that was eligible for this Cochrane review. Although research has identified a wide

    The case is presented of a 12-year old boy who sustained severe penetrating ocular trauma while playing on a domestic trampoline. A main spring broke under tension and the hook had struck the eye at high velocity and penetrated the sclera. Primary repair was undertaken but on review it became apparent the eye could not be salvaged. Evisceration was carried out and an orbital implant was placed. Post-operative cosmesis is acceptable. This type of injury has not been reported before. Adult supervision of children on trampolines is recommended to minimise the chance of serious injury.

  20. Seasonal and diurnal variations of ocular pressure in ocular hypertensive subjects in Pakistan.

    Qureshi, I A; Xiao, R X; Yang, B H; Zhang, J; Xiang, D W; Hui, J L

    1999-05-01

    Studies have been shown that intraocular pressure (IOP) shows a diurnal variation in ocular hypertensive subjects, but the amount of change differs from study to study. In recent years it has been noted that intraocular pressure is a dynamic function and is subjected to many influences both acutely and over the long term. The variability in the results may be due to negligence of factors that can affect IOP. Moreover, seasonal variations in the ocular hypertensive subjects have never been described. After placing control on those factors that can affect IOP, this study investigated seasonal and diurnal variations in IOP of ocular hypertensive subjects. IOP was measured each month over the course of 12 months with the Goldmann applanation tonometer in 91 ocular hypertensive male subjects. To see the diurnal changes, subjects were asked to stay in the hospital for 24 hours. The average IOP in the winter months was higher than those in spring, summer, and autumn. The IOP difference between winter and summer was (mean +/- sem) 2.9 +/- 0.9 mmHg (p < 0.001). The peak of mean IOP in diurnal variation curve (25.7 +/- 1.2 mmHg) appeared in the morning when the subjects had just awaken. The mean diurnal variation was found to be 4.2 +/- 0.6 mmHg (p < 0.001). This study confirms that seasons influence IOP and it shows diurnal variations. As compared to other nations, diurnal variations in ocular hypertensive subjects seem to be somewhat less in Pakistan. Knowledge of the seasonal and diurnal variations in IOP may help glaucoma screeners.

  1. Temporal dynamics of ocular position dependence of the initial human vestibulo-ocular reflex.

    Science.gov (United States)

    Crane, Benjamin T; Tian, Junru; Demer, Joseph L

    2006-04-01

    While an ideal vestibulo-ocular reflex (VOR) generates ocular rotations compensatory for head motion, during visually guided movements, Listing's Law (LL) constrains the eye to rotational axes lying in Listing's Plane (LP). The present study was conducted to explore the recent proposal that the VOR's rotational axis is not collinear with the head's, but rather follows a time-dependent strategy intermediate between LL and an ideal VOR. Binocular LPs were defined during visual fixation in eight normal humans. The VOR was evoked by a highly repeatable transient whole-body yaw rotation in darkness at a peak acceleration of 2800 deg/s2. Immediately before rotation, subjects regarded targets 15 or 500 cm distant located at eye level, 20 degrees up, or 20 degrees down. Eye and head responses were compared with LL predictions in the position and velocity domains. LP orientation varied both among subjects and between individual subject's eyes, and rotated temporally with convergence by 5 +/- 5 degrees (+/-SEM). In the position domain, the eye compensated for head displacement even when the head rotated out of LP. Even within the first 20 ms from onset of head rotation, the ocular velocity axis tilted relative to the head axis by 30% +/- 8% of vertical gaze position. Saccades increased this tilt. Regardless of vertical gaze position, the ocular rotation axis tilted backward 4 degrees farther in abduction than in adduction. There was also a binocular vertical eye velocity transient and lateral tilt of the ocular axis. These disconjugate, short-latency axis perturbations appear intrinsic to the VOR and may have neural or mechanical origins.

    Proton therapy has been used for the treatment of Ocular Tumors, showing control in most cases as well as conservation of the eyeball, avoiding the enucleation. The protons provide higher energetic deposition in depth with reduced lateral spread, compared to the beam of photons and electrons, with characteristic dose deposition peak (Bragg peak). This technique requires large particle accelerators hampering the deployment a Proton Therapy Center in some countries due to the need for an investment of millions of dollars. This study is related to a new project of an electromagnetic unit of proton circular accelerator to be coupled to the national radiopharmaceutical production cyclotrons, to attend ocular therapy. This project evaluated physical parameters of proton beam circulating through classical and relativistic mechanical formulations and simulations based on an ion transport code in electromagnetic fields namely CST (Computer Simulation Technology). The structure is differentiated from other circular accelerations (patent CTIT/UFMG NRI research group/UFMG). The results show the feasibility of developing compact proton therapy equipment that works like pre-accelerator or post-accelerator to cyclotrons, satisfying the interval energy of 15 MeV to 64 MeV. Methods of reducing costs of manufacture, installation and operation of this equipment will facilitate the dissemination of the proton treatment in Brazil and consequently advances in fighting cancer.
