    Full Text Available A utilização de micro-organismos probióticos é uma das mais atrativas opções para consumo humano, devido às suas excelentes propriedades funcionais. Considerando-se que o desenvolvimento de novos produtos tem adquirido crescente importância, objetivou-se, neste trabalho, avaliar a aceitabilidade de barras de cereais com micro-organismos potencialmente probióticos. Utilizou-se a escala hedônica estruturada de nove pontos, que contém os termos descritivos situados entre "gostei extremamente" e "desgostei extremamente". Os atributos avaliados foram: aparência, textura, sabor e impressão global. Foi também realizada uma pesquisa de intenção de consumo, utilizando-se uma escala de cinco pontos situados entre "nunca comeria" e "comeria sempre". A avaliação sensorial foi realizada por uma equipe de 36 indivíduos não treinados: professores, estudantes e funcionários da Universidade Federal do Espírito Santo, de ambos os sexos, com idades entre 20 e 40 anos. As amostras foram apresentadas aos provadores em ordem aleatória, de forma monádica, devidamente identificadas com números de três dígitos. A utilização da levedura Saccharomyces boulardii e da bactéria Lactobacillus acidophilus, por meio das diferentes formas de incorporação nas barras de cereais, não interferiu na qualidade sensorial e estrutural do produto. As quatro formulações de barra de cereais apresentaram boa aceitação sensorial quanto a aparência, textura, sabor e impressão global. A pesquisa de intenção de consumo revelou que mais de 60% dos provadores consumiriam o produto sempre ou frequentemente. A viabilidade dos micro-organismos por curto período de tempo torna necessária a realização de novos estudos, com o objetivo de aumentar a estabilidade destes micro-organismos durante a vida de prateleira do produto.

    Full Text Available Los fitoflagelados son un grupo heterogéneo de flagelados autotróficos, heterotróficos y mixotróficos, con importancia ecológica para los niveles tróficos en diferentes ecosistemas. Los fitoflagelados en costas del Pacífico mexicano (y en Latinoamérica en términos generales son virtualmente desconocidos, sólo se tienen pocos registros. El estudio de los fitoflagelados requiere de métodos complicados de recolección y análisis. Esta es, probablemente, la causa de la escasez de conocimiento de este grupo en áreas tropicales y subtropicales. Material recientemente recolectado a lo largo del Pacífico mexicano sirvió para el estudio de fitoflagelados marinos, incluyendo algunos tóxicos y potencialmente tóxicos. Se usaron muestras de plancton filtradas por gravedad y con bomba de vacío utilizando diferentes métodos de fijación y análisis. Se registran aquellas especies presentes o con posibilidad de estarlo que son potencialmente nocivas para el ecosistema marino pertenecientes a los Phyla Euglenophyta, Heterokontophyta y Haptophyta. Estas especies están distribuidas en el plancton, en aguas oceánicas y costerasThe phytoflagellates are a heterogeneous group of autotrophic, heterotrophic and mixothrophic flagellates of trophic importance in several ecosystems. As in the rest of Latin America, the phytoflagellates that occur in the Mexican Pacific coasts are virtually unknown except for a few records. Their study require complicated collection and analysis methods, a probable cause for the scarce knowledge of this group in tropical and subtropical areas. Material recently collected from various localities along the Mexican Pacific coasts was used to study phytoflagellates, including toxic and potentially toxic species. Plankton samples were treated by gravity and pump filtration, using different methods for fixation and analysis. The phyla Euglenophyta, Heterokontophyta and Haptophyta were found.

De julho de 2003 a setembro de 2004, massas fecais de equinos naturalmente infectados foram depositadas mensalmente sobre a gramínea. Sete dias após, amostras de fezes e gramínea foram coletadas semanalmente em diferentes horários (8, 13 e 17 horas, pesadas e processadas pela técnica de Baermann. O desenvolvimento, a sobrevivência e a migração das larvas infectantes nas fezes e na gramínea foram observados durante todo o período. A sobrevivência das L3 foi de até 15 semanas nas fezes e 12 semanas na gramínea no período seco e de nove e oito semanas, respectivamente, para o período chuvoso. No período chuvoso, maior número de L3 foi recuperado nas fezes e, no período seco, na gramínea. Condições climáticas influenciaram diretamente o número larvas infectantes. Pela análise multivariada, ficou demonstrado uma forte relação entre o tempo e o número de L3 nas fezes, sendo esta relação menos acentuada para a gramínea. Não se observou diferença significativa entre os horários de coleta.A study following the development and migration of Cyathostominae infective larvae was conducted from July 2003 to November 2004 in tropical climate, Baixada Fluminense, RJ, Brazil.

    Full Text Available A asma é uma doença inflamatória crônica, que representa um problema de saúde pública com altos números de óbitos e elevado impacto socioeconômico. A patologia é caracterizada pela fase imediata, mediada pela resposta aguda de células inflamatórias, e a tardia, que é responsável pela resposta com envolvimento de células específicas do sistema imunológico. Atualmente, os principais tipos de fármacos utilizados no tratamento da asma são os broncodilatadores e agentes antiinflamatórios, que aliviam os sintomas de broncoespasmo e diminuem a inflamação das vias aéreas. Entretanto, terapias com esses medicamentos não são totalmente eficazes e provocam efeitos adversos. A escassez de fármacos seguros e o baixo acesso da população carente aos tratamentos utilizados estimulam a busca de novas substâncias potencialmente úteis no tratamento da asma. Produtos naturais de origem vegetal representam um grande potencial farmacológico contra asma, uma vez que podem fornecer moléculas diversas com mecanismos específicos para tratamento e controle da patologia. A busca por terapias mais eficientes e específicas para o processo asmático mostra que a procura nos produtos naturais é promissora e possui um papel importante para a descoberta de novas terapias contra a asma.

It also intends to present works with original theoretical approach and original reflections able to reset the way we look at what is today already a centennial media. Having broadened the meaning of “beyond borders”, four foreign authors were invited to join the dossier. This is the first time they are being published in this country and so, in all cases, the articles where either written or translated into Portuguese.The dossier begins with “Radio is dead…Long live to the sound”, which is the transcription of a thought provoking lecture given by Armand Balsebre (Autonomous University of Barcelona – one of the most influential authors in the world on the Radio study field. It addresses the challenges such media is to face so that it can become “a new sound media, in the context of a new soundscape or sound-sphere, for the new listeners”. Andrew Dubber (Birmingham City University regarding the challenges posed by a Digital Era argues for a theoretical approach in radio studies which can consider a Media Ecology.

Os trabalhos foram desenvolvidos em condições controladas de 25 ºC de temperatura e fotoperíodo de 12 horas, para o bioensaio de germinação, e 24 horas, para o de alongamento da radícula. Os efeitos foram aquilatados tendo por contraste (testemunha a água destilada. Os resultados variaram em função da espécie receptora, da concentração e da parte da planta utilizada no preparo dos extratos. A inibição da germinação das sementes e do alongamento da radícula foi diretamente proporcional à concentração do extrato, com as mais intensas inibições observadas na concentração de 4%. Independentemente da espécie receptora, as sementes, seguidas das raízes, foram as principais fontes de substâncias químicas com atividades potencialmente alelopáticas no feijão-de-porco. A análise dos diferentes extratos brutos revelou que as substâncias químicas com atividades potencialmente alelopáticas presentes nas sementes do feijão-de-porco têm polaridade compreendida entre o acetato de etila e o metanol. Para o extrato bruto metanólico, concentrações a partir de 0,4% inibiram completamente a germinação das espécies receptoras, enquanto para M. pudica e S. occidentalis concentrações de 0,6 e 0,8% proporcionaram inibições da ordem de 100% para a germinação das sementes dessas espécies. A sensibilidade das espécies aos efeitos potencialmente alelopáticos variou na seguinte ordem decrescente: M. pudica > S. occidentalis > S. obtusifolia > U. lobata.Hydroalcoholic extracts from shoot, roots and seeds and seed raw extracts from Canavalia ensiformis were prepared to

    Full Text Available A infecção acidental humana pelo Angiostrongylus costaricensis ocorre com elevada prevalência em certas áreas do Brasil meridional, eventualmente se manifestando como doença abdominal severa. Profilaxia é importante, pois não hã tratamento medicamentoso. Um dos modos de transmissão é a ingestão de frutas e vegetais contaminados com a mucosidade de moluscos infectados, os hospedeiros intermediários deste parasita. Larvas de terceiro estágio obtidas do ciclo mantido em laboratório foram incubadas a 5°C por 12 horas, em vinagre, solução saturada de cloreto de sódio e hipocloríto de sódio a 1,5%. A viabilidade das lamas tratadas foi testada através da inoculação em camundongos albinos. Os percentuais de larvas que estabeleceram infecção foram: 0% com hipocloríto de sódio, 1,8% com salmora e 2,4% com vinagre. Em conclusão, todas as substâncias - de baixo custo e disponíveis nas áreas endêmicas - reduziram à população de lamas viáveis e podem ser úteis na descontaminação de alimentos para profilaxia da angiostrongilose abdominal.There is a high prevalence of accidental human infection with Angiostrongylus costaricensis in some areas in southern Brazil and sometimes it presents as severe intestinal disease. Prophylaxis is important since there is no medical treatment for the disease. The ingestion of fruits and vegetables contaminated with the mucous secretion of infected molluscs (the intermediate hosts is one of the proposed modes of transmission. Third stage lamae were incubated at 5°C for 12 hours, in solutions of saturated sodium chloride, vinegar and sodium hypochlorite 1.5%. The larvae had their viability tested through inoculation into albino mice. The percentage of larvae that established infection were 0% in the group treated with sodium hypochloride, 1.8% with NaCl and 2.4% with vinegar.

    Full Text Available A semente de Araucaria angustifolia, o pinhão, é comumente utilizada como alimento e propágulo para regeneração da espécie. A intensa predação das sementes pela fauna silvestre, que ocorre em áreas recém-plantadas por semeadura direta e em viveiros florestais, é um dos fatores adversos e desestimulantes à propagação da espécie. Este trabalho teve como objetivo verificar possíveis efeitos fitotóxicos de algumas substâncias naturais e sintéticas potencialmente repelentes à fauna silvestre, em sementes de Araucaria angustifolia "in vitro". O experimento foi conduzido no Laboratório de Fitopatologia e Fisiologia Vegetal do CAV / UDESC, no período de junho a dezembro de 2004. As sementes, após preparadas e tratadas com substâncias de origem vegetal e sintéticas, foram semeadas em bandejas plásticas com substrato constituído por vermiculita e colocadas em câmara de crescimento com temperatura, umidade relativa do ar, umidade do substrato e períodos de luz controlados. Foi adotado o delineamento experimental inteiramente casualizado, contendo 15 tratamentos, com 4 repetições de 10 pinhões. As substâncias testadas, isoladas ou em misturas, foram: extratos alcoólicos de fruto de pimenta vermelha, raiz de salsa tempero e, da parte aérea de losna, óleo essencial de eucalipto, óleo de linhaça, óleo de mamona, breu, oxicloreto de cobre, sulfato de cobre, enxofre e tinta látex PVA. Emissão de raiz, emissão da parte aérea, comprimento da raiz principal e da parte aérea foram avaliados 76 dias após a semeadura. As análises possibilitaram concluir que não houve efeitos fitotóxicos das substâncias testadas "in vitro" sobre as variáveis analisadas e que tais substâncias podem ser utilizadas nos experimentos de campo para testes de repelência aos animais consumidores de pinhões.

    Full Text Available O objetivo deste trabalho foi identificar marcadores moleculares relacionados à resistência do cafeeiro (Coffea arabica à ferrugem (Hemileia vastatrix. Foram identificadas sequências de DNA potencialmente envolvidas na resistência do cafeeiro a doenças, por meio de análise "in silico", a partir das informações geradas pelo Projeto Brasileiro do Genoma Café. A partir das sequências mineradas, foram desenhados 59 pares de iniciadores para amplificá-las. Os 59 iniciadores foram testados em 12 cafeeiros resistentes e 12 susceptíveis a H. vastatrix. Vinte e sete iniciadores resultaram em bandas únicas e bem definidas, enquanto um deles amplificou fragmento de DNA em todos os cafeeiros resistentes, mas não nos suscetíveis. Esse marcador molecular polimórfico amplificou uma região do DNA que corresponde a uma janela aberta de leitura parcial do genoma de C. arabica que codifica uma proteína de resistência a doenças. O marcador CARF 005 é capaz de diferenciar os cafeeiros analisados em resistentes e susceptíveis a H. vastatrix.

    To perform a list agreed by Argentinean experts and adapted to the local context containing potentially inappropriate (PI) medications in old people (OP) usingthe Delphi consensus technique optimized for this subject. A preliminary list of potentially inappropriate medications (PIM) was drawn up based on foreign PIM lists and a selective search in the scientific literature. The iterative Delphi process was used to submit the active pharmaceutical ingredients (APIs) of the preliminary PIM list to the panel of Argentinean experts. The analysis of theanswers to determine the arrival to the consensus was carried out applying three criteria specially defined for this purpose. After two Delphi rounds, it was not reached agreement about 12 APIs. The List of explicit criteria for PIAPIs for use in OP (IFAsPIAM List) was finally constituted by 128 APIs corresponding to 9 groups of the ATC classification system to which they were organized. In addition to each API, information justifying the unfavorable benefit/risk profile and therapeutic alternatives or recommendations/precautions was recorded. The group with the most PI APIs was N (NervousSystem) (60; 47%) followed by groups C (Cardiovascular) and M (Musculoskeletal). This study presents the first Latin American list of PIM in OP developed using an expert consensus technique. The IFAs PIAM List would contribute to the rational use of drugs in elderly population, constituting a valuable tool in Argentinean public health. Copyright © 2018. Published by Elsevier Inc.

    Full Text Available The seed of Araucaria angustifolia, “pinhão”, is becoming a alternative way of income for many families living at south and southeast of Brazil. The intensive attack on Paraná pine seeds by the wild fauna, that occur at newly-planted areas by direct sowing and at nursery of seedlings, is one of several adverses and distimulating factors to specie spreading. The objective of this work was to verify probable phytotoxics effects of some naturals and synthetics substances potentially repellentes to wild fauna, in Araucaria angustifolia seeds “in vitro”. The experiment was realized at Phytopatology and Plant Physiology Laboratory of Center of Agroveterinary Sciences, University of Santa Catarina State – Brazil, from june to december, 2004. The Paraná pine seeds, after preparation and treatment with vegetal and not vegetal substances, were sown in plastic trays with vermiculite substratum and put on cabin of growth with controlled temperature, relative humidity of air, humidity of substratum and photoperiods. It was adopted the randomized complete design with 15 treatments, with 10 seeds each treatment and with 4 repetitions. The tested substances separately or in mixtures were: extract of fruit of red pepper, root of parsley, stem and leaf of wormwood herb, lemon scented gum essential oil, linseed oil, castor bean oil, rosin, copper oxychloride, copper sulphate, sulphur and látex ink. The root emission, stem emission, length of main root and length of stem were evaluated 76 days after sowing and statisticaly analyzed. The analysis make possible to conclude that the tested extract do not have phytotoxic effect on seeds and that the substances tested “in vitro” can be used in field experiments, in repellence traits for Parana pine seeds consuming fauna. Keywords: effects fitotóxicos; pine seeds of Araucaria angustifolia; predação of seeds.

    Full Text Available Con el propósito de evaluar la abundancia y la composición de dinoflagelados potencialmente tóxicos asociados al material orgánico flotante (drift en la isla de San Andrés, se seleccionaron siete sitios de muestreo a lo largo de la margen Norte y Este, paralelos a la barrera arrecifal y a las principales praderas de fanerógamas marinas y macroalgas de la isla. Durante la época de mayor intensidad de vientos, se recolectaron muestras de drift; se identificaron los sustratos a especie y posteriormente se sumergieron en solución 1:1 agua de mar filtrada y solución de Transeau. Luego de agitar vigorosamente las muestras para remover los dinoflagelados, se tamizo la suspensión con una malla de 80 µm y el filtrado se observó al microscopio óptico. Se encontraron cinco sustratos, dos especies de pastos marinos y tres de macroalgas. Sobre los sustratos se identificaron doce especies de dinoflagelados, diez reportadas como tóxicas, causantes de diarrea, parálisis y ciguatera. La abundancia de dinoflagelados varió ampliamente con promedios máximos (±DE de 15 354±15 749 células/g peso seco de sustrato. De las especies de dinoflagelados, cinco son nuevos registros para San Andrés. No se encontraron diferencias significativas en los valores de diversidad de dinoflagelados entre drift y praderas de pastos y macroalgas, no obstante, la abundancia fue mucho mayor en el drift. Los resultados indican que el drift es un importante sustrato para dinoflagelados y dada su naturaleza flotante, representa tal vez el vector más importante para la dispersión de estos agentes de toxicidad en la isla. Para mitigar el efecto de eventos tóxicos asociados a dinoflagelados en salud pública, pesca y turismo, es necesario diseñar un plan de manejo del material orgánico flotante, que permita mejorar el entendimiento de su composición y dinámica temporal, monitorear las toxinas asociadas e implementar mecanismos de recolección y tratamiento.

    Full Text Available OBJETIVO: Determinar la prevalencia en el uso de productos infantiles orales entre menores de tres años de edad y medir su concentración de ftalatos, sustancias potencialmente tóxicas. MATERIAL Y MÉTODOS: Se realizó, en 1999, una entrevista domiciliaria a 199 madres de niños del área metropolitana de la ciudad de Toluca. Por cromatografía de gases se identificaron y cuantificaron diversos ftalatos de productos de uso oral empleados por los niños participantes y se estimó la contribución de estas fuentes a la ingesta diaria de ftalatos. RESULTADOS: La prevalencia de uso de estos productos fue de 13%, siendo mayor entre los niños, menores de 18 meses de edad, pertenecientes al estrato socioeconómico bajo. Las concentraciones variaron desde trazas hasta 67.0% del peso. La exposición media calculada proveniente de los productos manufacturados con policloruro de vinilo y ftalatos fue de 13.94 µg/ kg de peso/día, IC 95% (9.08, 18.89. CONCLUSIONES: La exposición a ftalatos proveniente de productos para chupar o morder se encuentra dentro de los límites reportados en otros países; sin embargo, otras fuentes pueden incrementarla. Dado que algunos ftalatos han mostrado ser tóxicos en el sistema reproductivo, y este potencial efecto es plausible en el hombre, es necesaria la investigación de otras fuentes y determinar la exposición total a través de biomarcadores.OBJECTIVE: To estimate the prevalence of oral product use in children less than three years of age, and to measure the concentration of phthalates as potentially toxic products. MATERIAL AND METHODS: In 1999, 199 mothers of children living in the city of Toluca agreed to household interviews. Samples of oral products used by the children were taken and analyzed by gas chromatography to identify and quantify phthalate concentrations, to estimate the daily intake of phthalates from this source.

Neste trabalho, objetivou-se caracterizar a atividade potencialmente alelopática do óleo essencial de Ocimum americanum (estoraque e determinar seus efeitos sobre a germinação de sementes e o desenvolvimento de duas espécies de plantas daninhas. O óleo essencial foi testado em concentrações variando de 100 a 2.000 mg L-1, considerando seus efeitos sobre a germinação de sementes (25 ºC de temperatura constante e fotoperíodo de 12 horas e o desenvolvimento da radícula e do hipocótilo (25 ºC de temperatura constante e fotoperíodo de 24 horas das plantas daninhas malícia (Mimosa pudica e mata-pasto (Senna obtusifolia. Fatores relacionados a concentração, especificidade das plantas receptoras e parâmetros analisados foram decisivos para os efeitos obtidos. A tendência geral foi de relação positiva entre concentração e efeito inibitório. Malícia foi mais sensível aos efeitos do que mata-pasto. Comparativamente, a germinação, seguida do desenvolvimento da radícula, foi afetada pelo óleo essencial em maior magnitude, ficando o desenvolvimento do hipocótilo como o de menor sensibilidade. Os efeitos observados podem ser atribuídos à presença, no óleo essencial, de monoterpenos, monoterpenos oxigenados, sesquiterpenos, alifáticos e fenilpropanoides, com destaque para os constituintes com atividade alelopática já comprovada, como o limoneno, a cânfora e o linalol.Essential oils are known for their several biological activities.

    Full Text Available Objective: to describe the main potentially life threatening conditions of women hospitalized in a maternal intensive care unit and their association with sociodemographic and obstetric variables. Methods: a crosssectional epidemiological study was carried out with 560 women admitted to an Intensive Care Unit. Results: the most prevalent conditions were: use of blood products and severe preeclampsia/eclampsia. There was a statistical association between women from the metropolitan region, in the age group of 20 to 34 years and who had previously given birth. Mothers who had a potentially life threatening condition presented a higher chance of having a child with Apgar <7 in the fifth minute and weigh of less than 1,500g. Conclusion: the use of blood products prevailed, followed by severe preeclampsia and eclampsia. A strong relation was identified between the origin, parity and potentially life threatening conditions, as well as between these and negative perinatal outcomes.

    Full Text Available This study was led with the purpose of evaluating the effectiveness of eugenol, beta-pinene and alpha-pinene in inhibiting the growth of potential infectious endocarditis causing gram-positive bacteria. The phytochemicals Minimum Inhibitory Concentration-MIC was determined by solid medium diffusion procedure, while the interference of the MIC values on the bacterial cell viability was performed by viable cells count. Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae and S. pyogenes strains were used as test microorganisms. The assayed phytochemicals showed effectiveness in inhibiting all assayed bacteria strains presenting MIC values between 2.5 and 40 µL/mL. Eugenol showed the lowest MIC values which were between 2.5 and 5 µL/mL for the most bacteria strains. MIC values found to the phytochemicals were able to inhibit the cell viability of S. aureus providing a total elimination of the bacteria inoculum in a maximum time of 24 hours of exposure. These data showed the interesting antibacterial property of the assayed phytochemicals and support their possible and rational use in the antimicrobial therapy.Este estudo foi conduzido com a proposta de avaliar a efetividade de eugenol, beta-pineno e alfa-pineno em inibir o crescimento de cepas de bactérias Gram-positivas potencialmente causadoras de endocardite infecciosa. A Concentração Inibitória Mínima-CIM dos fitoconstituintes foi determinada através do método de difusão em meio sólido, enquanto a interferência da CIM sobre a viabilidade celular bacteriana foi avaliada através da contagem de células viáveis. Cepas de Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae e S. pyogenes foram utilizadas como microrganismos teste nos ensaios antimicrobianos. Os fitoconstituintes ensaiados mostraram efetividade em inibir todas as cepas bacterianas utilizadas como microrganismos testes apresentando valores de CIM entre 2.5 e 40 µL/mL.

    Full Text Available Se presenta un modelo práctico de microbiología aplicada y biotecnología para aislar y caracterizar microorganismos, como una minús­cula muestra de la extensa biodiversidad de nuestros suelos. Se analiza su capacidad para producir depolimerasas e hidrolasas accesorias para la degradación de xiloglucanos-pectatos o glucoarabinoxilanos, con el fin de evaluar su potencial como degradadores de material vegetal. Se propone el uso del cultivo en paredes celulares vegetales como única fuente de carbono, como inductores de las actividades hidrolíticas, y el uso de las mismas paredes celulares y de xilano entrecruzado para purificar en forma rápida y económica enzimas degradadoras de celulosas y hemicelulosas. Con estos soportes de afinidad se logró un redimiento de purificación de xilanasas del 500% en un solo paso. Partiendo de 65 aislamientos se seleccionaron cinco, a los cuales se les hizo caracterización isoenzimática para celulasas y xilanasas. Se les sugiere como potencialmente útiles en compostaje y otros procesos industriales. Palabras clave: celulasas, hemicelulasas, cromatografía de afinidad, sustratos entrecruzados, diversidad microbiológica, compostaje.A practical, applied microbiology and biotechnology model is presented for isolating and characterising micro-organisms, this being a tiny part of the immense biodiversity of tropical soils. These microbes' ability to produce depolymerases and accessory hydrolases degrading xyloglucans-pectates or glucoarabinoxylans is analysed to evaluate their potential for degrading plant material. We propose culturing micro-organisms on the cell wall as main carbon source and as hydrolitic activity inducer. The same cell walls can be used for cross-linking xylan and for rapid, low cost purification of cellulose and hemicellose degrading enzymes. A 500% xylanase purification yield was obtained in a single step with these affinity supports. Out of the 65 isolates obtained were finally

    Full Text Available Cinnamomum zeylanicum Blume is known for a wide range of medicinal properties. This study aimed to assess the interference of C. zeylanicum essential oil on the growth and morphogenesis of some potentially pathogenic Aspergillus species. The essential oil presented strong antifungal effect causing the growth inhibition of the assayed strains and development of large growth inhibition zones. MIC50 and MIC90 values were 40 and 80 µL/mL, respectively. 80, 40 and 20 µL/mL of the oil strongly inhibited the radial mycelial growth of A. niger, A. flavus and A. fumigatus along 14 days. 80 and 40 µL/mL of the oil caused a 100% inhibition of the fungal spore germination. Main morphological changes observed under light microscopy provided by the essential oil in the fungal strains were decreased conidiation, leakage of cytoplasm, loss of pigmentation and disrupted cell structure indicating fungal wall degeneration. It is concluded that C. zeylanicum essential oil could be known as potential antifungal compound, particularly, to protect against the growth of Aspergillus species.Cinnamomum zeylanicum Blume é uma planta conhecida por apresentar ampla variedade de propriedades medicinais. Portanto, este estudo teve por objetivo avaliar a interferência do óleo essencial C. zeylanicum sobre o crescimento e morfogênese de algumas espécies de Aspergillus potencialmente patogênicas. O óleo essencial testado apresentou potente efeito antifúngico demonstrado pela visualização de grandes zonas de inibição de crescimento de todas as linhagens testadas. Os valores de CIM50 e de CIM90 foram 40 e 80 µL/mL, respectivamente. Nas concentrações de 80, 40 e 20 µL/mL o óleo demonstrou um potente efeito fumigante, inibindo o crescimento micelial radial de A. niger, A. flavus e A. fumigatus ao longo de 14 dias de exposição.

    An important part of the workshop was a series of invited presentations. The presentations were intended to both provide the participants with an understanding of various organisational approaches and activities as well as to stimulate the exchange of ideas during the small group discussion sessions. The presentation subjects ranged from current organisational regulations and licensee activities to new organisational research and the benefits of viewing organisations from a different perspective. There were more than a dozen invited presentations. The initial set of presentations gave the participants an overview of the background, structure, and aims of the workshop. This included a short presentation on the results from the regulatory responses to the pre-workshop survey. Representatives from four countries (Sweden, Canada, Finland, and the United Kingdom) expanded upon their survey responses with detailed presentations on both regulatory and licensee safety-related organisational activities in their countries. There were also presentations on new research concerning how to evaluate safety critical organisations and on a resilience engineering perspective to safety critical organisations. Below is the list of the presentations, the slides of which being available in Appendix 2: 1 - Workshop Welcome (Per-Olof Sanden); 2 - CSNI Working Group on Human and Organisational Factors (Craig Reiersen); 3 - Regulatory expectations on justification of suitability of licensee organisational structures, resources and competencies (Anne Edland); 4 - Justifying the suitability of licensee organisational structures, resources and competencies (Karl-Fredrik Ingemarsson); 5 - Nuclear Organisational Suitability in Canada (Andre Bouchard); 6 - Designing and Resourcing for Safety and Effectiveness (Germaine Watts); 7 - Organisational Suitability - What do you need and how do you know that you've got it?

    Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

    The report presents a wide, easily understandable description of presentation technique and man-machine communication. General fundamentals for the man-machine interface are illustrated, and the factors that affect the interface are described. A model is presented for describing the operators work situation, based on three different levels in the operators behaviour. The operator reacts routinely in the face of simple, known problems, and reacts in accordance with predetermined plans in the face of more complex, recognizable problems. Deep fundamental knowledge is necessary for truly complex questions. Today's technical status and future development have been studied. In the future, the operator interface will be based on standard software. Functions such as zooming, integration of video pictures, and sound reproduction will become common. Video walls may be expected to come into use in situations in which several persons simultaneously need access to the same information. A summary of the fundamental rules for the design of good picture ergonomics and design requirements for control rooms are included in the report. In conclusion, the report describes a presentation technique within the Distribution Automation and Demand Side Management area and analyses the know-how requirements within Vattenfall. If different systems are integrated, such as geographical information systems and operation monitoring systems, strict demands are made on the expertise of the users for achieving a user-friendly technique which is matched to the needs of the human being.

    Fluid inclusions (FI) are micro cavities present on crystals and imprison the mineralizer fluids, and are formed during or posterior to the mineral formation. Those kind of studies are very important for orientation of the engineer barrier projects for this purpose, in order to avoid that the solutions present in the mineral FI can affect the repository walls. This work proposes the development of FI micro compositional studies in the the hostess minerals viewing the contribution for a better understanding of the solution composition present in the metamorphosis granitoid rocks. So, micro thermometric, microchemical and characterization of the material confined in the FI, and the hostess minerals. Great part of the found FI are present in the quartz and plagioclase crystals.

    In Argentina almost 30% of the total end-use energy is consumed by the building sector. Within it, for residential use, the most usual fuel is natural gas. According to a 1997 survey, the known reserves would last approximately 32 years at the present rate of consumption. It is therefore essential to asses the performance of the building stock, in relation to energy conservation and the access to renewable energy resources, in order to plan the future urban development within the scope of maximum achievable energetic and environmental sustainability compatible whit the present urban morphology. The particular features of environments within the urban system, may significantly condition the access to and the availability of climatic resources. When the technical feasibility of a specific climatic design, for a new or refurbished building is analyzed, it is necessary to asses the available solar potential and potentially collecting areas, particularly within high density urban environment, where the shadows cast by tall neighboring buildings can significantly reduce solar access. A graphic-computational model developed for the purpose is described; it is a precise and easy to use tool. Departing from the loading of the buildings volumes coordinates, of a given urban environment and the solar position it will draw axonometric perspectives as seen from the sun. It will then calculate the areas, normal to the sun beams of the radiation prisms impinging on every building facade, for any hour or day of the year. The model was developed within the environment of the AutoCADR program.

    The Brazilian radiological accident that occurred in 1987, in Goiania, it was a terrible radiation episode. As a consequence, hundreds of people were contaminated due to the Cesium-137 radiation. Recently, many studies had shown that genome instabilities, such as, mutations, chromosomal aberrations, micronuclei formation and micro satellite instability and a delay on cellular death are usually reported on mammal cells exposed to ionizing radiation, being considered as a manly risk to humans. Mutations can be spontaneous, and the occurrence is dependent on the organism, or, induced, being associated to mutagenic exposition. Ionizing radiations are an example of physical and mutagenic agents that could harm the cell repair and could cause the development of many types of cancer. The evaluation of the biological effects of the ionizing radiation, in somatic and germ line cells, with a consequent determination of the radio-induced mutations, it is extremely important to estimate the genetic risks, manly in population exposed to radiation. The analyses of repetitive DNA sequences have been demonstrated that such sequences are prone to high rates of spontaneous mutations. The minisatellites and microsatellites have been used to demonstrate the induction of germ line mutation rates on mouse, humans, among others organisms. The aim of the present study was to analyze the frequency of microsatellite alterations to determine the mutation rates occurred in germ cells of the parents exposed to the ionizing radiation of the Cesium-137. The studied group was constitute of 10 families of individuals accidentally exposed to Cesium-137 and by the control group constituted by 645 healthy individuals who carried out paternity tests on 2009. We found only one mutation of paternal origin in the D8S1179 locus on the exposed group, being the mutation rate of 0.002. In the control group, we found 01 mutation on D16S539 loei and on D3S1358; 02 mutations on Penta E loeus; 04 mutations on D

    Full Text Available This study aimed to analyze affective and cognitive determinants of the professional work of individuals caring for patients with HIV/AIDS, in view of the risk and/or experience of accidental exposure to blood. We drew on the theoretical-methodological references of Fishbein & Ajzen and Maslow's theory. Fifty health care workers were evaluated using an attitudes questionnaire and a needs and motivations instrument. The research verified differences between answers by health care workers who had never suffered accidents and those who had already experienced accidental exposure to blood. Health care workers did their work activities motivated by the need for self-fulfillment and valued their own performance when they were able to meet the patients' emotional needs. Among health professionals who had never experienced accidental exposure to blood, the predominant beliefs was that patients feel remorse over having expose themselves to HIV. Accidental exposure to blood raises difficulties in personal life. Technical aspects are also associated with the possibility of accidental exposure to blood.O objetivo deste estudo foi analisar determinantes afetivos e cognitivos que influenciam o trabalho de profissionais que cuidam de pessoas vivendo com o HIV/ AIDS, frente ao risco ou experiência de exposição acidental a material biológico potencialmente contaminado (MBPC.

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

    Conduziu-se um experimento de incubação aeróbica em laboratório para estimar o nitrogênio potencialmente mineralizável (No através de modelos matemáticos. Avaliaram-se os efeitos da calagem e do manejo de solos sob vegetação nativa, plantio convencional e plantio direto, na mineralização cumulativa do nitrogênio. Os parâmetros estimados de No variaram de 187 a 23 mg N kg-1 de solo, sendo que os valores mais altos foram encontrados nos latossolos sob vegetação natural, argilosos e com maiores teores de carbono e nitrogênio total. Valores menores de No foram encontrados no Neossolo. O modelo hiperbólico estima valores mais altos de No que os modelos exponencial simples e duplo, independentemente do manejo dos solos. Os valores de No estimados são proporcionais aos teores de carbono, nitrogênio total e argila dos solos; porém são menores em função da intensidade de uso dos solos: plantio convencional < plantio direto < vegetação nativa. Os modelos exponencial simples e exponencial duplo estimam potenciais de mineralização semelhantes. O modelo exponencial duplo estima que a fração de nitrogênio facilmente mineralizável representa menos de 2% do nitrogênio total dos solos. A calagem deprimiu a mineralização de nitrogênio em todos os solos sob plantio convencional; sob plantio direto, aumentou a mineralização de nitrogênio nos Latossolos, porém diminui no Neossolo.

    PALAVRAS-CHAVE: Carbono orgânico; nitrogênio; sistemas de cultivo; calagem; cerrados.

    An aerobic incubation laboratory trial was undertaken to assess the effects of cropping systems and liming of undisturbed soils and soils under conventional tillage and notillage on the cumulative nitrogen mineralization and on the potentially mineralizable nitrogen (No. The estimated No

  13. Alarm filtering and presentation

    International Nuclear Information System (INIS)

    Bray, M.A.

    1989-01-01

    This paper discusses alarm filtering and presentation in the control room of nuclear and other process control plants. Alarm generation and presentation is widely recognized as a general process control problem. Alarm systems often fail to provide meaningful alarms to operators. Alarm generation and presentation is an area in which computer aiding is feasible and provides clear benefits. Therefore, researchers have developed several computerized alarm filtering and presentation approaches. This paper discusses problems associated with alarm generation and presentation. Approaches to improving the alarm situation and installation issues of alarm system improvements are discussed. The impact of artificial intelligence (AI) technology on alarm system improvements is assessed. (orig.)

The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

    This part summarizes the content of the six following presentations: 1. IAEA requirements/guidance for the decommissioning safety case (Mike Bell, IAEA); 2. Safety case in an EIA context (Patrick O'SULLIVAN, The Netherlands); 3. Plant configuration and the D and D licensing process (Eugenio GIL LOPEZ and Pedro CARBONERAS, Spain); 4. Accident assessment (Ivo TRIPPUTI, Italy; Ingmar LUND, Sweden); 5. Balancing radiological and industrial risk in the safety case (Pascal DEBOODT, Belgium); 6. The safety case for safe store and dormancy periods (Paul WOOLLAM, UK). Following the six presentations, the WPDD members discussed the safety case in an open discussion led by the Topical Session Chair, Frances Taylor. The discussion was wide-ranging, and topics varied from the standards that apply to releases to the environment during safe store, to decommissioning parallels with other major processing industries and facilities (such as oil rigs). Frances Taylor steered the discussion toward addressing the questions that the WPDD Core Group had proposed for the topical session. The Chair, the Rapporteur, and some members of the group sensed that the presentations had covered such an wide variety of issues, and that the content of the presentations themselves differed so greatly, that it would be difficult to distill a position paper from the information gathered, as had been the mandate from the Core Group. In addition, the meaning of the term 'Safety Case' differed greatly among participants in the topical session. Some took the term to mean the analysis and document that the implementor provides to the regulator, describing how operations will be performed safely. Others considered the term to mean the overall safety and risk conditions inherent in a nuclear facility during operations or decommissioning. With the differences in presentations and with the meaning of the terminology remaining unclear, the WPDD participants did not reach consensus conclusions on December 5, 2001

    Metachromatic leukodystrophy (MLD) is a rare demyelinating disease (prevalence 1:40 000), also called arylsulfatase A deficiency (ARS-A), which may present with neurological and psychiatric symptoms. Clinical assessment may be difficult, due to unspecific signs and symptoms. A case is presented of a 16 year-old female patient seen in psychiatry due to behavioural changes, psychosis, and with impaired overall performance. She was initially diagnosed with schizophrenia, but the Nuclear Magnetic Resonance (NMR) scan and laboratory tests lead to the diagnosis of MLD. Copyright © 2016 Asociación Colombiana de Psiquiatría.

    We are presenting two cases of Sirenomelia (Mermaid Syndrome), which is an extreme example of the caudal regression syndrome. It invariably presents with lower limb fusion, sacral and pelvic bony anomalies, absent external genitalia, imperforate anus, and renal agenesis or dysgenesis. There are approximately 300 cases reported in the literature, 15% of which are associated with twinning, most often monozygotic. The syndrome of caudal regression is thought to be the result of injury to the caudal mesoderm early in gestation. One of our cases survived for 12 days after birth. This new born had an unusually high anorectal anomaly in which the colon was ending at the level of mid transverse colon, fused lower limbs and genital anomalies. Ultrasound of the abdomen revealed horseshoe kidney. Colostomy was performed on day 2 of life. The second case encountered was a stillborn baby on whom an autopsy was performed. PMID:26023366

    We are presenting two cases of Sirenomelia (Mermaid Syndrome), which is an extreme example of the caudal regression syndrome. It invariably presents with lower limb fusion, sacral and pelvic bony anomalies, absent external genitalia, imperforate anus, and renal agenesis or dysgenesis. There are approximately 300 cases reported in the literature, 15% of which are associated with twinning, most often monozygotic. The syndrome of caudal regression is thought to be the result of injury to the caudal mesoderm early in gestation. One of our cases survived for 12 days after birth. This new born had an unusually high anorectal anomaly in which the colon was ending at the level of mid transverse colon, fused lower limbs and genital anomalies. Ultrasound of the abdomen revealed horseshoe kidney. Colostomy was performed on day 2 of life. The second case encountered was a stillborn baby on whom an autopsy was performed.

    Information management can be a daunting process for clinicians, health care providers and policy makers within the health care industry. This chapter discusses the importance of information classification and information architecture in the information economy and specific challenges faced within the health care industry. The healthcare sector has industry specific requirements for information management, standards and specifications for information presentation. Classification of information based on information criticality and the value in the health care industry is discussed in this paper. Presentation of information with reference to eHealth standards and specifications for healthcare information systems and their key requirements are also discussed, as are information architecture for eHealth implementation in Australia. This chapter also touches on information management and clinical governance since the importance of information governance is discussed by various researchers and how this is becoming of value to healthcare information management.

    Francisella tularensis is a gram-negative coccobacillus that causes a condition commonly referred to as tularemia. There has been a dramatic increase in tularemia cases reported in South Dakota, many of which were challenging to diagnose due to atypical clinical manifestations. We describe an interesting case of pneumonic tularemia and summarize six similar cases, several of which presented with lung nodules suggestive of malignancy. According to the literature, this is only the third outbreak of pneumonic tularemia reported in the U.S. We believe it is important for clinicians to be aware of the increased incidence of tularemia in the area and to be vigilant in the diagnosis and management of these atypically presenting cases.

    In electron probe microanalysis the objective has always been to gain the maximum information from a sample. To this end efforts have been directed at increasing detection efficiency, reducing the size of the excitation volume, analysing more difficult specimens and improving the accuracy of quantitative measurements whilst, at the same time, attempting to minimize the complexity of the analysis. The present paper comments on the progress that has been made in this areas, focuses on the latest hardware and software developments taking place and looks forward to how these may impact on the technique of EPMA.

    We herein describe a second Japanese case of sarcoidosis presenting Addison's disease. A 52-year-old man was diagnosed with sarcoidosis based on clinical and laboratory findings, including bilateral hilar lymphadenopathy and elevated levels of serum angiotensin-converting enzyme and lysozyme, as well as the presence of noncaseating epithelioid granulomas. The patient also exhibited general fatigue, pigmentation, weight loss, hypotension and hyponatremia, suggestive of chronic adrenocortical insufficiency. An endocrine examination confirmed primary adrenocortical insufficiency. This case suggests the direct involvement of sarcoid granuloma in the adrenal glands.

    2007-01-01

    The basic principles of the Newtonian theory of gravitation are presented in a way which students may find more logically coherent, mathematically accessible and physically interesting than other approaches. After giving relatively simple derivations of the circular hodograph and the elliptical orbit from the inverse-square law, the concept of gravitational energy is developed from vector calculus. It is argued that the energy density of a gravitational field may reasonably be regarded as -g 2 /8πG, and that the inverse-square law may be replaced by a Schwarzschild-like force law without the need to invoke non-Euclidean geometry

    This paper proposes that there is a major error in the present perception of cancer risk from exposure to low level radiation from internal man-made fission products like strontium-90. The author's Second Event theory is discussed which advances the basis that fission products are different in radiation risk terms. Since the scientific community has been so ready to dismiss this idea out of hand, the author also explores scientific culture and scientific revolutions. The evidence that the idea is broadly right is surveyed and finally some studies that could be undertaken to prove or disprove the author's contention are outlined. (UK)

    The radiotherapy is one of the most widely spread and commonly used method in treating tumors of different localization. A detailed analysis of benefits and possible side effects along with evaluation of the risk factors allows preventing one of the most difficult complication, and namely the radiation myelopathy. The delayed form of such a disease is distinguished by a pronounced unfavorable prognosis. The presented case provoked the discussion of difficulties in performing differential diagnosis, as well as the importance of determining the localization of vulnerable tissues as regards the target organ exposed to radiotherapy.

    The presentation topic is California's approach to license application review in meeting financial assurances for the proposed Ward Valley site. The purpose of the presentation is to provide information on specific financial assurance provisions contained in 10 CFR Part 61 and how California intends to satisfy those requirements. Also, as rate setter, California intends to demonstrate how it will assure allowable costs to the rate base though a financial prudency review. The key provisions of financial assurance are: 10 CFR Section 61.61 - This provision requires an applicant to demonstrate its ability to finance licensed activities; 10 CFR Section 61.62 - This provision requires an applicant to provide assurance that sufficient funds will be available for site closure and stabilization; and 10 CFR Section 61.63 - This provision requires an applicant to provide 'a copy of a binding arrangement, such as a lease, between the applicant and the disposal site owner, so that sufficient funds will be available to cover the costs of the institutional control period.' To assist California in its determination of financial assurance compliance to be demonstrated by the applicant for Part 61 requirements, is NUREG guidance document 1199 'Standard Format and Content of a License Application for a Low-Level Radioactive Waste (LLRW) Disposal Facility.' The detailed financial assurance provisions of NUREG 1199 are then embodied in NUREG 1200, 'Standard Review Plant for the Review of a License Application for a LLRW Disposal Facility.'

    Rett syndrome, a degenerative neurological disorder of girls, has a classical presentation and typical EEG findings. The electroencephalograms (EEGs) of 7 girls whose records have been followed from the onset of symptoms to the age of 5 or more are presented. These findings are tabulated with the Clinical Staging System of Hagberg and Witt-Engerström (1986). The records show a progressive deterioration in background rhythms in waking and sleep. The abnormalities of the background activity may only become evident at 4-5 years of age or during stage 2--the Rapid Destructive Stage. The marked contrast between waking and sleep background may not occur until stage 3--the Pseudostationary Stage. In essence EEG changes appear to lag behind clinical symptomatology by 1-3 years. An unexpected, but frequent, abnormality was central spikes seen in 5 of 7 girls. They appeared to be age related and could be evoked by tactile stimulation in 2 patients. We hypothesize that the prominent 'hand washing' mannerism may be self-stimulating and related to the appearance of central spike discharges.

    This time, we would like to address copyright violations (again) - but with a twist. While previous articles focussed on “Music, videos and the risk for CERN” or on software licences, the focus is now on using photos, music and images “found” on the Web for presentations, publications and web pages…   Just recently, a video produced for CERN and published on YouTube and Facebook used background music from a contemporary popular artist. However, the people responsible failed to obtain the appropriate permission to actually use that music. They thought that having bought it on iTunes was sufficient. But it was not: “buying” means you have the right to listen, but not the right for further distribution or re-publication. As a result, the videos were pulled from YouTube and Facebook. Similarly, how many of us integrate graphics and images “found” on the Web into our presentations?  How many of us...

    Die Urknallmaschine, an Austrian film by Gerd Baldauf, narrated by Norbert Frischauf (Alpha Österreich - ORF, 2009).  In CERN’s gigantic complex particles are accelerated to almost the speed of light, brought to collision and made to divide into even smaller particles. Public opinion of CERN’s research is also divided. Sceptics fear that black holes may be created. Might the goal to study the origin of the world lead to its destruction? The Austrian researcher Norbert Frischauf worked at CERN for many years. With his guidance it is possible to explore the world’s largest research centre, get a glimpse of the fascinating work the scientists do there and take a crash course in particle physics. Die Urknallmaschine will be presented on Friday, 25 June from 13:00 to 14:00 in the Main Auditorium. Language: German

    Abdominal pregnancy, a rare diagnosis, belongs to the ectopic pregnancy group, the leading cause of pregnancy related exitus. The positive diagnosis is very difficult to establish most often in an acute setting, leading to a staggering percent of feto-maternal morbidity and mortality. We present the case of 26-weeks-old abdominal pregnancy with partial feto-placental detachment in a patient, after hysteroscopy and in vitro fertilization, which until the acute symptoms that led to emergency laparotomy went unrecognized. The patient recovered completely and satisfactorily after surgery and, due to the high risk of uterine rupture with regard to a second pregnancy, opted for a surrogate mother. Abdominal pregnancy can be regarded as a difficult to establish diagnosis, with a greater chance in case of increased awareness. It is compulsory to be well informed in order not to be surprised by the diagnosis and to apply the correct treatment immediately as the morbidity and mortality rate is elevated.

    Full Text Available Background: Trichinosis is a widespread zoonosis acquired by ingestion of undercooked meat infected with the larvae of Trichinella parasites. The disease has variable clinical manifestations ranging from asymptomatic to fatal. Majority of infections is caused by Trichinella spiralis, although there are some cases caused by other species. The dramatic decline of trichinosis reflects changes in industrial practices and increased public awareness. The majority of human cases are now associated with wild game meat and noncommercial pork. The case of previously healthy, young man with trichinosis is presented. The disease was determined with serologic testing and cured with albendazole. The source of infection has not been determined.Conclusions: In patients with fever, mialgias and eosinophilia infection with tissue nematodes should always be taken in consideration. In those who have recently consumed raw or undercooked pork and wild game meat we should think about trichinosis. The disease is rare in Slovenia.

    2007-01-01

    Medical practice leadership teams, often consisting primarily of physicians with limited financial backgrounds, must make important business decisions and continuously monitor practice operations. In order to competently perform this duty, they need financial reports that are relevant and easy to understand. This article explores financial reporting and decision-making in a physician practice. It discusses reports and tools, such as ratios, graphs, and comparisons, that practices typically include in their reports. Because profitability and cash flow are often the most important financial considerations for physician practices, reports should generally focus on the impact of various activities and potential decisions upon these concerns. This article also provides communication tips for both those presenting practice financial information and those making the decisions. By communicating effectively, these leaders can best use financial information to improve decision-making and maximize financial performance.

    In contingency of a nuclear emergency event, requiring application of intervention measures on a federal scale, Canada has of a plan ensuring the compatibility of the plans of different provinces and serving as interface between federal and provincial authorities. Exclusive of a nuclear attack against North America, by nuclear emergency it is understood an accident resulting in radionuclide release. This is called the Plan of federal intervention in case of nuclear emergency. 'Sante Canada' is the federal authority responsible for intervention in case of nuclear emergency and it has the task of preparing and coordinating the actions on a federal scale.Should the plan be set in action and if the emergency has repercussions upon the agricultural sector, the sustaining organism will be 'Agriculture and agroalimentaire Canada' which in case of emergency acts through the channels of the National System of intervention in the agro-alimentary sector (SNIUA). The paper presents the objectives, the principles of organization and operation, the responsibilities and the plans which SNIUA has in its charge to implement in case of emergency

  8. Present energy status

    1988-04-01

    This paper reviews the past and present situation of the World Oil Market and assumes future trends and possible future evolution. Low oil prices between 1950 and 1973 have contributed to an exceptional growth of oil demand during more than 20 years which was more and more supplied by OPEC. The oil shocks of 1973 and 1979 have dramatically changed this situation. Some of the most important changes have been the emergence of non-OPEC new oil producers, the growth of substitute energies, especially natural gas and nuclear power, on the supply side; and substantial decrease of energy consumption in many industrialized countries which has greatly reduced oil demand to OPEC on the demand side. Today this situation seems somewhat stabilized (after the reversal of world oil prices in 1986) and OPEC is producing around 18 million b/day as against a producing capacity of about 30 million b/day. It is generally considered that in coming years oil prices will remain relatively low (or occasionally even become lower than today) due to excess oil production capacity and relative abundance of other types of energy. However, many experts think that these trends can be reversed when oil supply will more and more concentrate again in the Middle East; but it is hard to say if this will begin in 1995, 2000, 2010.

  9. The laryngocele; case presentation

    2016-05-01

    Full Text Available Laryngocele is a rare pathology, but because of their clinical evolution and the symptoms they generate, they should always be considered as a differential diagnosis when investigating neck masses. A laryngocele is basically a herniation of the mucosa of the laryngeal ventricle (Morgagni's ventricle arising usually from the saccular region. This herniation may remain confined to the larynx - in which case the laryngocele is internal- or expand through the thyro-hyoid membrane into the structures of the neck - thus being called an external laryngocele. Usually the laryngocele has both an internal and external component thus being a mixed laryngocele. Diagnosis of laryngoceles still relies heavily on clinical signs such as tympanism, easily depressible neck mass, indirect laryngoscopy, but is now simplified by imagistic investigations (ultrasound, CT and MRI. However, the treatment of this condition is exclusively surgical and consists of total excision of the laryngocele, as well as proper identification of the point of origin from the saccule and also the final suture of the breach in order to prevent recurrence. Investigation of possible causes of obstruction of the laryngeal ventricle should always be performed (because of the possibility of an underlying malignancy as well as a follow-up protocol of the patient, given the risk of relapse. We present a recently diagnosed case of a 32 year old man with mixed laryngocele, which we have operated in our clinic.

    The author discuss the up to date interpretation of the concept of antibiotics and antibiotic research, as well as the present role of various natural, semisynthetic and synthetic antibiotic compounds in various areas of the human therapy. The origin and the total number of all antibiotics and applied antibiotics in the practice, as well as the bioactive microbial metabolites (antibiotics) in other therapeutical, non-antibiotic fields (including agriculture) are also reviewed. The author discusses main problems, such as increasing (poly)resistance, virulence of pathogens and the non-scientific factors (such as a decline of research efforts and their sociological, economic, financial and regulatory reasons). A short summary of the history of Hungarian antibiotic research is also provided. The author briefly discusses the prospects in the future and the general advantages of the natural products over synthetic compounds. It is concluded that new approaches for the investigation of the unlimited possibilities of the living world are necessary. The discovery of new types or simply neglected (micro)organisms and their biosynthetic capabilities, the introduction of new biotechnological and genetic methods (genomics, metagenom, genome mining) are absolutely required in the future.

    The IKONOS satellite has been operational since January 2000 and was the first commercial satellite collecting imagery with 1 meter resolution. The current life expectancy of the satellite is 10 years. Since the launch, Space Imaging Inc. (the owner of the satellite) supplied IKONOS imagery to users in many vertical markets, such as: agriculture, defense, oil & gas and telecommunications. This oral presentation will give comprehensive information about IKONOS and the future: * Block II, the successor of IKONOS. Space Imaging expects to launch in 2004 a new high-resolution satellite, ensuring both continuity and (for some years) a tandem operation with IKONOS, greatly improving the availability of imagery. * Space Imaging affiliates. IKONOS imagery collected, processed and sold by regional affiliates. These regional affiliates are strategically located around the world, like Japan Space Imaging (Tokyo), Space Imaging Middle East (Dubai) and Space Imaging Eurasia (Ankara, Turkey). * Technical briefing IKONOS. IKONOS (compared to other commercial high-resolution satellites) has superior collection capabilities. Due to, the higher orbit altitude, local reception of the imagery, bi-directional scanning and the high agility of the satellite, is the IKONOS satellite capable to collect the imagery relative quickly.

Storage-agnostic, Pydio is a simple layer that can be deployed on top of any storage backend, thus providing scalability and high-availability out-of-the-box. Charles du Jeu is the lead developer of the solution and will briefly present its feature and how it can fit for research and engineering purpose. See https://pyd.io/ for more information.

  13. THE UPSIDE OF PRESENTISM

    Lynn Fendler

    2009-01-01

    Full Text Available El presentismo es visto generalmente como un mal necesario en historiografía. Este artículo explora lo positivo de esta inevitabilidad. Aplicando un enfoque filosófico al análisis discursivo en la tradición de la nueva historia cultural, se distingue -de una parte-¿ entre un uso estratégico del presentismo, y -de otra- un enfoque racionalista en historia. El artículo concluye considerando algunas implicaciones políticas en historiografía de las explicaciones racionalistas y de las explicaciones estratégicamente presentistas. Los modos de comprensión racionalistas inscriben las expectativas del pasado en las visiones del futuro; asignando al historiador el papel de profeta; y perpetuando nociones de agentes ahistóricos. En contraste, las historias estratégicamente presentistas incorporan una orientación que deliberadamente emplea las lentes y perspectivas del presente en orden a tener en cuenta supuestos y perspectivas actuales. Cuando las asunciones son examinadas en relación a las perspectivas presentistas, dichos presupuestos sueltan su rienda en el pensamiento. Dado que el presentismo es inevitable, no debe ser desestimado por completo, sino que debe ser una cuestión sondeada y examinada críticamente. Con dicho foco, el presentismo estratégico en la historiografía debe posibilitar una reflexión sobre los límites de lo que es posible pensar.

    Implementing a sustainable local energy policy involves a long term reflection on the general interest, energy efficiency, distributed generation and environmental protection. Providing services on a market involves looking for activities that are profitable, if possible in the 'short-term'. The aim of this conference is to analyse the possibility of reconciling these apparently contradictory requirements and how this can be achieved. This conference brings together the best specialists from European municipalities as well as important partners for local authorities (energy agencies, service companies, institutions, etc.) in order to discuss the public-private partnerships concerning the various functions that municipalities may perform in the energy field as consumers and customers, planners and organizers of urban space and rousers as regards inhabitants and economic players of their areas. This document contains the summaries of the following presentations: 1 - Performance contracting: Bulgarian municipalities use private capital for energy efficiency improvement (K. VIDOLOV, Varna (BG)), Contracting experiences in Swiss municipalities: consistent energy policy thanks to the Energy-city label (B. DUFOUR-FALLOT and T.

    structure (chemical order, anisotropy, charge transfer, magnetic order) versus an external parameter like temperature, pressure, magnetic or electric field. Modern crystallography is also extended to the study of very small crystals, powders, ill-ordered or non-crystallized materials. Thus presently, crystallography is concerned with any solid that “scatters” an incident beam. Nevertheless, as quoted by A. Guinier, “the problems facing crystallographers have only changed, ... new ones have appeared which require reflection and imagination, ... and which in turn may still bring much joy to all those who like crystallography” [4]. Such developments open up crystallography to modern materials like artificial ones and nanostructures with low- and/or multi-scaled-periodicities and/or extremely small “crystal size” and to materials of the “real world”, with mixtures of phases and/or amorphous contribution and/or defects, a common characteristic of ancient materials analysed in patrimonial research. In our contribution we will show by selected examples that these improvements were allowed (i) by the use of powerful sources, apparatus and detectors which allow micro-diffraction, in-situ diffraction, spectroscopy, resonant scattering, inelastic scattering, coherent scattering, (ii) by the development of methods like diffraction anomalous fine structure (DAFS), pair distribution function (PDF), simulated annealing, single object reconstruction, (iii) by combination of scattering and spectroscopy and by combination of scattering and microscopy. Such combination of different approaches is very efficient and, as said by H. Curien at the IUCr Bordeaux Congress in 1990, “in crystallography, there is a constant alternation between the crystal space and its associated reciprocal space, ... the alternation between experiment and model building is another feature of crystallography activity ..., the crystallographer relies both on his computer and on his diffractometer

    The goal of most presentations is to engage audience participants. Effective presenters go beyond content expertise to connect with audiences through various techniques, formats, and presentation styles. Mayer's theory of multimedia learning, neurocognitive factors, and the assertion-evidence approach are essential elements that presenters can use if they have not had formal training in creating presentations. Tips are offered on how to connect with the audience and how to avoid known pitfalls. ©2017 American Association of Nurse Practitioners.

  10. Isolated Torticollis May Present as an Atypical Presentation of Meningitis

    Directory of Open Access Journals (Sweden)

    Roger Chirurgi

    2012-01-01

    Full Text Available Background. Bacterial meningitis is a life-threatening medical emergency that requires urgent diagnosis and treatment. Diagnosis is infrequently missed if the patient presents with the classic symptoms of fever, headache, rash, nuchal rigidity, or Kernig or Brudzinski sign. However, it may be less obvious in neonates, elderly, or immunocompromised patients. Meningitis which presents as isolated torticollis, without any other signs or symptoms, is exceedingly rare. Objective. To identify an abnormal presentation of meningitis in an adult immunocompromised patient. Case Report. We present a case of an adult diabetic male who presented multiple times to the ED with complaint of isolated torticollis, who ultimately was diagnosed with bacterial meningitis. Conclusion. We propose that in the absence of sufficient explanation for acute painful torticollis in an immunocompromised adult patient, further evaluation, possibly including a lumbar puncture may be warranted.

    2014-08-01

    Full Text Available This article analyzes the communicative and educational practices performed by female Colombian scientists self-recognized as lesbians. The objective of this study was twofold. Firstly, it seeks to understand the ways in which non-heteronormative sexualities have the potential to re-shape the production/circulation of expert knowledge; especially that which favors androcentric values. Secondly, it seeks to problematize and re-dimension the marginal place of these communicative and educational practices in relation to the production of expert knowledge. Methodologically, the study is based on an ethnographic approach to the edu-communicative practices of eight lesbian scientists in Colombia. Theoretically, it takes the feminist discussions that have studied matters of care in techno-science as a reference point for the analysis.

    One way to build knowledge in nursing is to share research findings or clinical program outcomes. The dissemination of these findings is often a difficult final step in a project that has taken months or years to complete. One method of sharing findings in a relaxed and informal setting is a poster presentation. This method is an effective form for presenting findings using an interactive approach. The milieu of a poster presentation enables the presenters to interact and dialogue with colleagues. Guidelines for size and format require that the poster is clear and informative. Application of design helps to create visually appealing posters. This article summarizes elements of designing and conducting a poster presentation.

  3. Atypical presentations of Wolframs syndrome

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

    Morandi, S; Manna, A; Sabattini, E; Porcellini, A

    1996-08-01

    We describe a case of a very unusual presentation of rhabdomyosarcoma. An 18-year-old woman presented with symptoms and signs compatible with acute leukemia. The bone marrow picture showed diffuse involvement sustained by undifferentiated blasts that turned out to be of striated muscle origin by immunochemistry. While it is well known that rhabdomyosarcoma may metastasize to the bone marrow, extensive marrow involvement with leukemic spread as a unique clinical manifestation is extremely rare. Our observation further confirms the need to consider rhabdomyosarcoma among the possible differential diagnoses in patients who present with a leukemic picture and atypical blasts lacking all hematopoietic markers.

    Science.gov (United States)

    Scripture, D L

    1998-02-01

    Hyperthyroidism is the most common disorder of the thyroid. Patients typically present with complaints consistent with a hypermetabolic state, including nervousness, weight loss, heat intolerance, palpitations, irritability, and tremor. This case report reviews a 34-year-old woman who presented with unilateral upper extremity weakness, weight gain, and an episode of atrial fibrillation, the latter coinciding with a 36-hour lack of sleep and excess alcohol and caffeine intake. Although an extensive neurologic evaluation failed to identify any abnormality, the patient's laboratory analysis revealed elevations in thyroxine (T4) and triiodothyronine (T3) levels with unsuppressed thyroid-stimulating hormone levels. Subsequent treatment with the antithyroid drug methimazole (Tapazole) provided complete relief of symptoms. This case report illustrates how health care providers can be diverted to pursue a neurologic etiology when muscle weakness presents as a unilateral symptom. Plausible alternative causes for muscle weakness and other symptoms are presented.

    Thyrotoxic crisis is a medical emergency requiring early diagnosis and urgent management, which can be challenging due to its diverse clinical presentations. While common presentations include fever, sweating, palpitations, tremors and confusion, presence of jaundice is rare. We report a 35-year-old male who presented with jaundice due to cholestasis along with other features of thyrotoxic crisis due to Graves' disease. He had a good clinical recovery with resolution of cholestasis following treatment for thyrotoxic crisis. Jaundice can be a rare manifestation of thyrotoxic crisis, and should be considered in the differential diagnosis when other clinical features of thyrotoxic crisis are present. However secondary causes of jaundice should be looked into and excluded.

    Energy Technology Data Exchange (ETDEWEB)

    Papp, A.L. III; Blattner, M.M.

    1994-05-16

    The centralized audio presentation manager addresses the problems which occur when multiple programs running simultaneously attempt to use the audio output of a computer system. Time dependence of sound means that certain auditory messages must be scheduled simultaneously, which can lead to perceptual problems due to psychoacoustic phenomena. Furthermore, the combination of speech and nonspeech audio is examined; each presents its own problems of perceptibility in an acoustic environment composed of multiple auditory streams. The centralized audio presentation manager receives abstract parameterized message requests from the currently running programs, and attempts to create and present a sonic representation in the most perceptible manner through the use of a theoretically and empirically designed rule set.

    Full Text Available Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial bleeding with high mortality and usually related to traumatic labor or coagulation disorders. Subgaleal hemorrhage complications result from massive bleeding. We present a neonate with unremarkable family history and uneventful pregnancy with a vaginal delivery with no instrumentation, presenting with severe subgaleal bleeding at 52 hours of life. Aggressive support measures were implemented and bleeding managed. The unexpected bleeding lead to a coagulation study and the diagnosis of severe hemophilia A. There were no known sequelae. This case shows a rare hemophilia presentation reflecting the importance of coagulation studies when faced with unexplained severe bleeding.

    Objective: To document the clinical presentation and epidemiology of various types of acute leukemia with their respective referral source at a tertiary level centre in Peshawar. Study Design: An observational study. Place and Duration of Study: Department of Pathology, Hayatabad Medical Complex (HMC), Peshawar, from January 2011 to May 2012. Methodology: A total of 618 bone marrow biopsy reports were reviewed. All biopsy reports labeled as acute leukemia were reviewed for age, gender, address, referring unit, diagnosis on bone marrow examination, presenting complaints, duration of illness and findings of clinical examination. Results: Ninety-two patients were diagnosed as suffering from acute leukemias (15%). ALL was most prevalent (46%), followed by AML (38%) and undifferentiated acute leukemia (16%). Males were affected more compared to females (60% vs. 40%). ALL and AML were predominant in pediatric (64%) and adults (77%) patients respectively. Patients from Afghanistan accounted for 33% of all cases followed by Peshawar (14%). Fever (77%), pallor (33%) and bleeding disorders (23%) were the main presenting complaints. Enlargement of liver, spleen and lymph nodes together was associated with ALL compared with AML (p = 0.004). Conclusion: ALL-L1 and AML-M4 were the most common sub-types. Fever, pallor and bleeding disorders were the main presenting complaints. Enlargement of liver, spleen and lymph nodes was more frequently associated with ALL compared to AML. (author)

  9. Summary of presentations and discussions

    International Nuclear Information System (INIS)

    Takeuchi, Mitsuo

    2008-01-01

    In December 2007, the Forum on Stakeholder Confidence discussed its theme entitled 'Link between research, development and demonstration (RD and D) and stakeholder confidence'. It was remarked that regulators need a technical demonstration to aid in evaluating the safety case. Local stakeholders appreciate the opportunity to visualise technological arrangements. In both cases, demonstration adds to confidence in the feasibility of solutions. Some believe there is an important role for analogues in communication with stakeholders, if handled with integrity. To explore and benchmark current practices, it was decided to hold a topical session at the 9. regular meeting of the FSC on 4 June 2008 regarding the use of analogues for confidence building. The session opened with an introductory presentation by the session rapporteur. This incorporated input provided for the purpose by FSC members in cooperation with their country's representative to the NEA RWMC 'Integration Group on the Safety Case'. Three speakers then presented the various uses of analogues by implementers, regulators and scientists to build their own confidence; a fourth speaker dealt with the experience of using natural analogues in public information. The presentations addressed the use of analogues in the field of geological disposal of high-level waste (HLW) and long-lived intermediate level (ILW-LL) radioactive waste. Then the FSC participants split into two working groups for discussion. The outcome of these discussions was reported in plenary on 6 June 2008 and it was agreed to publish proceedings of the session. The present summary, prepared by the session rapporteur with input from the NEA Secretariat, captures the main points heard in the course of the event. It combines data from the formal presentations and remarks made in discussion. The latter represent viewpoints expressed by a group whose primary focus is not natural analogues but rather stakeholder interests. The summary and viewpoints

    2017-01-01

    A 25-year-old man presented with a 2-month history of dysphagia and past history of pulmonary and intestinal tuberculosis. A barium swallow showed a point of constriction 42 mm above the gastroesophageal junction. Computed tomography revealed large opacities in bilateral lung fields, encroaching more on the esophagus. The lesion progressively compressed the esophagus as it moved inferiorly. A right posterolateral thoracotomy was performed for sub-anatomical resection of the mass. A biopsy revealed homogenous whirling hyalinized collagen fibers, highly suggestive of pulmonary hyalinizing granuloma, with no evidence of malignancy. Pulmonary hyalinizing granuloma should be considered in the differential diagnosis of longstanding dysphagia.

  11. An unusual presentation of presentation of a branchial cleft cyst.

    Vemula, Rahul; Greco, Gregory

    2012-05-01

    Branchial cleft cysts are congenital anomalies that arise from the aberrant embryological development of the branchial apparatus. The location of a branchial cleft cyst is determined by which branchial cleft failed to obliterate during embryological development, with the second branchial cleft cyst being the most commonly recognized lesion. Although the most common location for branchial cleft cysts is between the external auditory canal and the level of the clavicle, the literature does describe unusual locations. We present a case a 15-year-old boy who had an enlarging lesion on his back that had been present since birth. A presumptive radiologic diagnosis of lymphangioma circumscriptum was made. Upon excision of the lesion and pathologic examination, it was determined to be a branchial cleft cyst. The patient had an uneventful postoperative course, and no recurrence was noted after a 2-year follow-up. Our clinical report demonstrates a lesion on the posterior thorax that proved to be a branchial cleft cyst and should always be part of the differential diagnosis for soft tissue masses of the thorax.

    2008-01-01

    Full Text Available Nocardia spp are gram-positive, aerobic, acid-fast bacteria which exist as saprophytes in nature. Invasive disseminated infections are particularly common in immunocompromised or debilitated hosts. Superficial infections with Nocardia spp occur as a result of local trauma and contamination of the wound. Clinically, it presents as acute infection (abscesses or cellulitis, mycetoma, or sporotrichoid infection. Differential diagnosis includes eumycetoma, chromomycosis, blastomycosis, coccidioidomycosis, sporotrichosis, tuberculosis, botryomycosis, syphilis, yaws, and neoplasia. Its diagnosis is confirmed by demonstrating the causative organism in exudates (as granules, tissue specimens, or cultures. Early diagnosis will obviate need for drastic surgical measures as early institution of chemotherapy is effective in most patients. However, its diagnosis is often delayed due to diverse clinical presentations and for want of clinical suspicion, particularly in non-endemic areas. This paper presents 4 clinical forms of this not so uncommon disease, emphasizing the importance of high index of clinical suspicion, especially in non-endemic regions; and the significance of repeated examination of exudates for Nocardia granules for an early diagnosis.

  4. Industry Presentation to Regulatory Workshop

    International Nuclear Information System (INIS)

    Treasure, Mark

    2012-01-01

    Mr. Mark Treasure from EDF NGL gave a presentation on industry perspectives on safety culture oversight. Mr. Treasure is the Nuclear Inspection and Oversight Manager within the Safety and Regulation Division. The presentation started with an explanation of the role of the nuclear inspection and oversight group (internal regulator), and their current approach to internal oversight of safety culture. A key element of the current internal regulatory oversight program is Management and Leadership Assessments. These are carried out by a team including management peers from other plants to enhance credibility. Findings can be linked to safety performance, and typically identify issues in areas such as accountability arrangements and strategic focus of the leadership team. Safety indicators have also been introduced to show trends in safety management and safety performance for each EDF UK nuclear power plant. A periodic nuclear safety culture survey is also carried out to identify focus areas and progress. The presentation included discussion on views of the role of the nuclear regulator. Important aspects were identified as: - Supporting the internal regulator by seeking to understand before taking enforcement action, maintaining an open dialogue and recognising that this area is complex and that there is rarely a 'silver bullet' solution. - Communication: being visible and actively discussing safety improvement, and use of language which emphasises nuclear safety rather than legal compliance. - Positive reinforcement to recognise efforts and encourage further improvement

    Full Text Available The last decade has witnessed a growing interest in the development of web interfaces enabling both multiple ways to access contents and, at the same time, fruition by multiple modalities of interaction (point-and-click, contents reading, voice commands, gestures, etc.. In this paper we describe a framework aimed at streamlining the design process of multi-channel, multimodal interfaces enabling full reuse of software components. This framework is called the eXtensible Presentation architecture and Language (XPL, a presentation language based on design pattern paradigm that keeps separated the presentation layer from the underlying programming logic. The language supplies a methodology to expedite multimodal interface development and to reduce the effort to implement interfaces for multiple access devices, by means of using the same code. This paper describes a methodology approach based on Visual Design Pattern (ViDP and Verbal Design Pattern (VeDP, offering examples of multimodal and multichannel interfaces created with the XPL Editor.

    Since the development of quantum physics in the early part of the 1900s, this field of study has made remarkable contributions to our civilization. Some of these advances include lasers, light-emitting diodes (LED), sensors, spectroscopy, quantum dots, quantum gravity and quantum entanglements. In 1998, the NASA Langley Research Center established a quantum technology committee to monitor the progress in this area and initiated research to determine the potential of quantum technology for future NASA missions. The areas of interest in quantum technology at NASA included fundamental quantum-optics materials associated with quantum dots and quantum wells, device-oriented photonic crystals, smart optics, quantum conductors, quantum information and computing, teleportation theorem, and quantum energetics. A brief review of the work performed, the progress made in advancing these technologies, and the potential NASA applications of quantum technology will be presented.

  7. Diabetic Myonecrosis: An Atypical Presentation

    Directory of Open Access Journals (Sweden)

    José Hernán Martínez

    2013-01-01

    Full Text Available Diabetic myonecrosis is a frequently unrecognized complication of longstanding and poorly controlled diabetes mellitus. The clinical presentation is swelling, pain, and tenderness of the involved muscle, most commonly the thigh muscles. Management consists of conservative measures including analgesia and rest. Short-term prognosis is good, but long-term prognosis is poor with most patients dying within 5 years. Failure to properly identify this condition will expose the patient to aggressive measures that could result in increased morbidity. To our knowledge this is the first case reported in which there was involvement of multiple muscle groups including upper and lower limbs.

    Nanophthalmos is an uncommon developmental ocular disorder characterized by a small eye with short axial length, high hyperopia and high lens/eye volume ratio due to arrested development of the globe in all directions. Different types of fundus changes can rarely occur with nanophthalmos. We describe five cases of nanophthalmos, each of them presenting with a different fundus appearance. Our case series highlights variability of pigmentary changes from retinal flecks to bone spicules and bull's eye maculopathy, which are rare in the combinations described here. (author)

    Experimental techniques for reactivity determination of a reactor have been one of the long standing subjects in reactor physics. Recently, such a requirement was proposed by the reactor designers and operators that the values of reactivity should be measured more accurately. This is because importance is emphasized for the role of reactivity to the performance of reactor safety, economics and operability. Motivated by the requirement, some remarkable progresses are being made for the improvement of the experimental techniques. Then, the present review summarizes the research activities on this subject, identifies several reactor physics problems to be overcome, and makes mention of the future targets. (auth.)

    Polyglandular autoimmune syndrome (PGA) and eosinophilic granulomatosis with polyangiitis (EGPA) do not seem to represent a coincidental association. A case of a 15-year-old boy is reported who presented with severe systemic inflammation, perimyocarditis and cardiogenic shock, in whom EGPA was initially suspected and later diagnosed with autoimmune adrenalitis with PGA. The severity of the systemic inflammation and perimyocarditis suggests a more widespread autoimmune-mediated process. Autoimmune adrenal insufficiency should be considered in all cases of pericarditis and perimyocarditis, especially when the severity of clinical manifestations exceeds the expected for the severity of the cardiac findings, as timely identification and prompt treatment may be life-saving.

    Authors present the case of a woman aged 59 operated on in three occasions due to the presence of neck nodules. Biopsy from two of them informs that be about a pleomorphous liposarcoma. After 6 years she came to consultation by a picture of high retrosternal pain and slight dyspnea. Thorax tomography shows a solid mass in anterior mediastinum. We made exeresis of a 10 cm diameter soft solid mass. Pathological Anatomy Service reported on relapse of a pleomorphous liposarcoma. In general, the postoperative course was satisfactory. Literature reviewed shows that the surgical treatment is the more used procedure in these cases. (author)

    Full Text Available "nTuberculosis (TB still represents a major public health problem worldwide. The primary form of disease is most often localized to the lung. In a minority of patients, progressive pulmonary disease spreads to other organ systems through self inoculation via infected sputum, blood and lymphatic system, establishing the secondary form of tuberculosis. We present a patient that was referred to us with complaint of ulcerative mouth lesions from 3 months ago. In physical examination multiple erythematous and irregularly ulcerative lesions affecting soft palate area, uvula and anterior tonsillar pillar was noted bilaterally. Punch biopsy was done from several points that revealed chronic granulomatous inflammation. Ziehl-Nielsen staining of cultured specimen demonstrated acid-fast bacilli. Chest X-ray showed apical pulmonary involvement, suggesting tuberculosis infection. Patient was treated with anti-tuberculosis 4 drugs regimen. In the one year follow-up period after complete treatment; patient didn't have any evidence of disease. Oral and oropharyngeal TB lesions are uncommon, it is estimated that only 0.05-5% of total TB cases may present with oral manifestations, but should be an important consideration in the differential diagnosis of lesions that appear in the oral cavity and oropharynx. The secondary form is more frequent and involves mainly the tongue but involvement of pharynx is quite rare condition. Although tuberculosis of oropharynx is relatively rare, with the increasing incidence of tuberculosis, it must be considered in the differential diagnosis of atypical ulcerative lesions of the mouth and oropharynx.

    Clinical and neuroimaging findings of glioblastomas (GBM) at an early stage have rarely been described and those tumors are most probably under-diagnosed. Furthermore, their genetic alterations, to our knowledge, have never been previously reported. We report the clinical as well as neuroimaging findings of four early cases of patients with GBM. In our series, early stage GBM occurred at a mean age of 57 years. All patients had seizures as their first symptom. In all early stages, MRI showed a hyperintense signal on T2-weighted sequences and an enhancement on GdE-T1WI sequences. A hyperintense signal on diffusion sequences with a low ADC value was also found. These early observed occurrences of GBM developed rapidly and presented the MRI characteristics of classic GBM within a few weeks. The GBM size was multiplied by 32 in one month. Immunohistochemical analysis indicated the de novo nature of these tumors, i.e. absence of mutant IDH1 R132H protein expression, which is a diagnostic marker of low-grade diffuse glioma and secondary GBM. A better knowledge of early GBM presentation would allow a more suitable management of the patients and may improve their prognosis. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Teratology is the science that studies the causes, mechanisms, and patterns of abnormal development. The authors present an updated overview of the most important milestones and stages of the development of modern teratology. Development of knowledge and society led to the recognition that causes of congenital developmental disorders (CDDs) might be caused by various mechanical effects, foetal diseases, and retarded or arrested development of the embryo and foetus. Based on the analysis of the historical development of hypotheses and theories representing a decisive contribution to this field, we present a survey of the six Wilson's fundamental principles of teratology. The aim of observing these principles is to get insight into developmental relations and to understand mechanisms of action on the level of cell populations (elementary morphogenetic processes), tissues and organs. It is important to realise that any negative intervention into the normal course of these processes, either on genetic or non-genetic basis, inevitably leads to a sequence of subsequent changes resulting in CDDs. Moreover, the classical toxicologic monotonic dose-response paradigm recently has been challenged by the so-called "low dose-hypothesis", particularly in the case of endocrine active substances. These include some pesticides, dioxins, polychlorobiphenyls (PCBs), and bisphenol A. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 65 to 70% of all congenital defects classified as having an unknown etiology. Today CDDs include any birth defect, either morphological, biochemical, or behavioural.

    Full Text Available Three unusual clinical forms of sporotrichosis described in this paper will be a primer for the clinicians for an early diagnosis and treatment, especially in its unusual presentations. Case 1, a 52-year-old man, developed sporotrichosis over pre-existing facial nodulo-ulcerative basal cell carcinoma of seven-year duration, due to its contamination perhaps from topical herbal pastes and lymphocutaneous sporotrichosis over right hand/forearm from facial lesion/herbal paste. Case 2, a 25-year-old woman, presented with disseminated systemic-cutaneous, osteoarticular and possibly pleural (effusion sporotrichosis. There was no laboratory evidence of tuberculosis and treatment with anti-tuberculosis drugs (ATT did not benefit. Both these cases were diagnosed by histopathology/culture of S. schenckii from tissue specimens. Case 3, a 20-year-old girl, had multiple intensely pruritic, nodular lesions over/around left knee of two-year duration. She was diagnosed clinically as a case of prurigo nodularis and histologically as cutaneous tuberculosis, albeit, other laboratory investigations and treatment with ATT did not support the diagnosis. All the three patients responded well to saturated solution of potassium iodide (SSKI therapy. A high clinical suspicion is important in early diagnosis and treatment to prevent chronicity and morbidity in these patients. SSKI is fairly safe and effective when itraconazole is not affordable/ available.

    2009-01-01

    A set of extensions of the Satellite Orbit Analysis Program (SOAP) enables simultaneous and/or sequential presentation of information from multiple sources. SOAP is used in the aerospace community as a means of collaborative visualization and analysis of data on planned spacecraft missions. The following definitions of terms also describe the display modalities of SOAP as now extended: In SOAP terminology, View signifies an animated three-dimensional (3D) scene, two-dimensional still image, plot of numerical data, or any other visible display derived from a computational simulation or other data source; a) "Viewport" signifies a rectangular portion of a computer-display window containing a view; b) "Palette" signifies a collection of one or more viewports configured for simultaneous (split-screen) display in the same window; c) "Slide" signifies a palette with a beginning and ending time and an animation time step; and d) "Presentation" signifies a prescribed sequence of slides. For example, multiple 3D views from different locations can be crafted for simultaneous display and combined with numerical plots and other representations of data for both qualitative and quantitative analysis. The resulting sets of views can be temporally sequenced to convey visual impressions of a sequence of events for a planned mission.

  1. Bilirubin present in diverse angiosperms.

    Bilirubin is an orange-yellow tetrapyrrole produced from the breakdown of heme by mammals and some other vertebrates. Plants, algae and cyanobacteria synthesize molecules similar to bilirubin, including the protein-bound bilins and phytochromobilin which harvest or sense light. Recently, we discovered bilirubin in the arils of Strelitzia nicolai, the White Bird of Paradise Tree, which was the first example of this molecule in a higher plant. Subsequently, we identified bilirubin in both the arils and the flowers of Strelitzia reginae, the Bird of Paradise Flower. In the arils of both species, bilirubin is present as the primary pigment, and thus functions to produce colour. Previously, no tetrapyrroles were known to generate display colour in plants. We were therefore interested in determining whether bilirubin is broadly distributed in the plant kingdom and whether it contributes to colour in other species. In this paper, we use HPLC/UV and HPLC/UV/electrospray ionization-tandem mass spectrometry (HPLC/UV/ESI-MS/MS) to search for bilirubin in 10 species across diverse angiosperm lineages. Bilirubin was present in eight species from the orders Zingiberales, Arecales and Myrtales, but only contributed to colour in species within the Strelitziaceae. The wide distribution of bilirubin in angiosperms indicates the need to re-assess some metabolic details of an important and universal biosynthetic pathway in plants, and further explore its evolutionary history and function. Although colour production was limited to the Strelitziaceae in this study, further sampling may indicate otherwise.

    Although a few case reports about hypertensive anaphylaxis (HA) are available in the present literature, there is no study about the prevalence of HA. In this study, we review our cases with anaphylaxis presenting with hypertension and ascertain its prevalence. The documents of the patients who had anaphylactic reactions after the procedures performed for the diagnosis and treatment of allergic diseases in GATA Haydarpasa Clinic of Allergy and Immunology between January 2010 and December 2014 were retrospectively reviewed. Within the study period, 324 patients had undergone 4332 procedures in which 62 of them had developed anaphylaxis. During the procedures, the rate of anaphylaxis was found to be 1.43 %. The rate of HA among the anaphylaxis patients was 12.9 % (8 of 62 patients). During treatments, 2 patients received adrenaline injections without any adverse reaction. HA may be seen at a considerable rate during an anaphylactic reaction. Anaphylaxis and hypertension can be recovered by adrenaline injection when required. According to the best of our knowledge, this study is the first original study about the prevalence of HA in English-language medical literature.

    Full Text Available Cases of pulmonary aspergilloma without any predisposing factors are rarely reported. Clinical presentation varies from case to case. Here, we report a case of pulmonary aspergilloma in a 60-year-old male patient who was admitted to the Intensive Respiratory Care Unit with spontaneous pneumothorax. The patient had a history of dyspnea on exertion since 9 months and mild haemoptysis since the last 6 months. A computerised tomographic scan of the lungs showed a lesion in the left main bronchus along with obstructive emphysema of the right lung, moderate pneumothorax and mediastinal emphysema. Bronchoscopy was performed and the biopsy samples were processed for histopathological examination and culture on Sabouraud′s dextrose agar, which yielded growth of Aspergillus flavus. Repeat sputum samples also yielded the growth of A. flavus . The patient responded to intravenous liposomaamphotericin B and intercostal drainage.

    Site selection has been going on since the earliest times. The process has evolved through the Industrial Revolution to the present period of exploding population and environmental awareness. Now the work must be done both with increasing sophistication and greater transparency. Modern techniques for site selection have been developed during the last two decades or so, utilizing a teachable body of knowledge and a growing literature. Many firms and individuals have contributed to this growing field. The driving force has been the need for such a process in siting and licensing of critical facilities such as nuclear power plants. A list of crucial, documented steps for identifying social impacts and acceptability are provided. A recent innovation is the self-selection method developed by government. The Superconducting Supercollider serves as an example of this approach. Geological or geologically dependent factors often dominate the process. The role as engineering and environmental geoscientists is to provide responsible leadership, consultation, and communication to the effort

    Full Text Available Neurocysticercosis (NCC is the most common helminthic infestation of the central nervous system (CNS and a leading cause of acquired epilepsy worldwide. The common manifestations of NCC are seizures and headache. The NCC as a cause of pseudobulbar palsy is very unusual and not reported yet in the literature. A pseudobulbar palsy can occur in any disorder that causes bilateral corticobulbar disease. The common etiologies of pseudobulbar palsy are vascular, demyelinative, or motor neuron disease. We report a 38-year-old female patient who presented with partial seizures and pseudobulbar palsy. The MRI brain showed multiple small cysts with scolex in both the cerebral hemispheres and a giant intraparenchymal cyst. Our patient responded well to standard treatment of neurocysticercosis and antiepileptics.

    Hadrontherapy is a high-precision technique in cancer radiation therapy, which allows obtaining a superior conformal treatment with respect to photons used in conventional radiation therapy. To reach this ambitious goal without reducing the patient throughput needed in a hospital-based environment, the physical and radiobiological properties of charged hadrons, protons and carbon ions in particular, have to be exploited at best, making use of the most modern technologies issued from research in nuclear and particle physics. In the present days, we are assisting to a continuous technological challenge, leading to the conception and to the development of innovative methods and instruments. In this paper, the most relevant challenges in dose delivery systems, gantries, imaging, quality assurance and particle accelerators are reviewed.

Ebola virus (EBOV) has now been around for almost 50 years. In this review, we discuss past and present outbreaks of EBOV and how those variants evolved over time. We explore and discuss selective pressures that drive the evolution of different Ebola variants, and how they may modify the efficacy of therapeutic treatments and vaccines currently being developed. Finally, given the unprecedented size and spread of the outbreak, as well as the extended period of replication in human hosts, specific attention is given to the 2014-2015 West African outbreak variant (Makona).

    1980-01-01

    History of the production and use of tritium, as well as handling techniques, are reviewed. Handling techniques first used at Lawrence Livermore National Laboratory made use of glass vacuum systems and relatively crude ion chambers for monitoring airborne activity. The first use of inert atmosphere glove boxes demonstrated that uptake through the skin could be a serious personnel exposure problem. Growing environmental concerns in the early 1970's resulted in the implementation by the Atomic Energy Commission of a new criteria to limit atmospheric tritium releases to levels as low as practicable. An important result of the new criteria was the development of containment and recovery systems to capture tritium rather than vent it to the atmosphere. The Sandia National Laboratories, Livermore, Tritium Research Laboratory containment and decontamination systems are presented as a typical example of this technology. The application of computers to control systems is expected to provide the greatest potential for change in future tritium handling practices

    We presented 4 cases studies of criptococosis, all of them with pulmonary compromise, diagnosed at Hospital Santa Clara in a period of 5 years. It's important to note that none of the patients were HIV positive. In the first case studied the cellular immune compromise has, a multifactorial origin: rheumatoid arthritis and the administration of corticoids. In the second case studied, SLE can explain its origin. In the third case studied, because of the short hospital stay, the investigation with respect to the etiology of the immune-compromise was limited. In the fourth case studied, because of a low CD4 count Elisa immunoassay for HIV was repeated without its confirmation. Spontaneous recuperation was obtained, being free of infection for a period of five years

    Full Text Available In this study we evaluated the association of celiac disease in 81 children with autoimmune disease and genetic syndromes over a two years periods (January 2014 to July 2016 in Pediatric Clinic in Constanta. Because the extraintestinal symptoms are an atypical presentation of celiac disease we determined in these children the presence of celiac disease antibodies: Anti-tissue Transglutaminase Antibody IgA and IgA total serum level as a screening method followeds in selective cases by Anti-tissue Transglutaminase Antibody IgG, anti-endomysial antibodies, deamidated gliadin antibodies IgA and IgG and intestinal biopsia. In our study 8 patients had been diagnosed with celiac disease with extraintestinal symptoms, of which 4 with type 1 diabetes, 1 patient with ataxia, 2 patients with dermatitis herpetiformis and 1 patient with Down syndrome that associate also autoimmune thyroiditis, alopecia areata, enamel hypoplasia.

    Full Text Available The close proximity of the styloid process to many of the vital neurovascular structures in the neck makes it clinically significant. The styloid process is said to be elongated if it is longer than 3.0 cm in length. Anatomical variations are very common and clinical symptoms arising from such variations have to be recognized. Elongated styloid processes may cause chronic throat pain along with foreign body sensation, dysphagia, vague facial pain, and otalgia. Surgical excision of an elongated styloid is considered as a satisfactory treatment for such cases. Here, we present a unique case of bilaterally elongated styloids that could be visualized just by depressing the tongue, when they appeared like the tusks of an elephant in the oropharyngeal region.

  15. Splenic abscess: a rare presentation

    Directory of Open Access Journals (Sweden)

    Mohit Bhatia

    2015-01-01

    Full Text Available Splenic abscess is a rare clinical entity with an incidence of 0.2-0.7% in autopsy-based studies. When untreated, splenic abscess is associated with nearly 100% mortality; in treated patients, the mortality rate is 16.6% during the first 90 days. It mostly occurs in patients with neoplasia, immunodeficiency, trauma, diabetes or splenic infarct. The incidence of splenic abscess is thought to be growing because of the increase in the number of immunocompromised patients who are particularly at risk for this disease and also because of the widespread use of diagnostic modalities. However, the optimal treatment for this remains unclear. We present a case of a 42-year-old man diagnosed with multiloculated splenic abscess and was subjected to splenectomy.

    Instruments are essential for accounting, for surveillance and for protection of nuclear materials. The development and application of such instrumentation is reviewed, with special attention to international safeguards applications. Active and passive nondestructive assay techniques are some 25 years of age. The important advances have been in learning how to use them effectively for specific applications, accompanied by major advances in radiation detectors, electronics, and, more recently, in mini-computers. The progress in seals has been disappointingly slow. Surveillance cameras have been widely used for many applications other than safeguards. The revolution in TV technology will have important implications. More sophisticated containment/surveillance equipment is being developed but has yet to be exploited. On the basis of this history, some expectations for instrumentation in the near future are presented

    The authors report here a case of hemangioma of the left parietal bone which presented headache and papilledema. This patient is a 37-year-old female who had, prior to admission, complained of increasing headache for one year and blurred vision for three months. She had no history of head injury. Local physical examinations revealed a slight bulging in her left parietal region which was insensitive to palpation and not adherent to the overlying scalp. Neurological examinations revealed bilateral papilledema and an incongruous bitemporal upper quadrant defect in the visual field. All the other neurological and laboratory data were normal. A plain skull roentogenogram showed a 9 x 9 cm osteolytic and characteristic honeycomb lesion in the parietal region. Systemic bone survey revealed a similar lesion in the right tibia which was not histologically examined. A marked accumulation of isotopes was detected on the bone scintigrams at both lesions. Selective external carotid angiograms demonstrated a tumor stain fed by the superficial temporal, occipital, and middle meningial arteries. CT scans of the brain and skull clearly showed a local thickening of and structural changes in the skull bone and also a mass effect on the brain and lateral ventricle. The lesioned bone was removed en bloc and replaced by an artificial bone. It was highly vascular, but not adherent to the overlying dura. The post-operative course was uneventful, and the headache and papilledema disappeared. Hemangioma of the skull presenting marked hyperostosis, as reported above, seems to be rare. In addition, in this case, skeletal angioma without any clinical manifestation was detected. Clinical and radiological pictures of the hemangioma of the skull and other bones were briefly discussed.

    1985-01-01

    Seven patients with amebic liver abscess presenting as pleuropulmonary disease were admitted to hospital initially because of pulmonary symptoms and were found to have amebic liver disease. Three categories of pleuropulmonary involvement included reactive inflammation of the pleura or lung, rupture of a hepatic abscess into the pleural space and rupture of a hepatic abscess into the bronchial airways. The preferred medical treatment is with metronidazole, but rupture of hepatic amebic abscess into the pleural space requires drainage in addition to medical therapy. In contrast, rupture into the bronchus may provide spontaneous drainage so that only medical therapy is needed. Recovery from amebiasis in all three categories is generally complete. Morbidity and mortality increase with failure to correctly identify amebic infection of the liver as the underlying cause. Because, in new cases, no findings specifically suggest that pleuropulmonary disease is a complication of hepatic amebic abscess, this possibility needs to be considered, especially in persons who are at risk of having been infected with amebae.

    Full Text Available The propagation of antibiotic resistance increases the chances of major infections for patients during hospitalization and the spread of health related diseases. Therefore finding new and effective solutions to prevent the proliferation of pathogenic microorganisms is critical, in order to protect hospital environment, such as the surfaces of biomedical devices. Modern nanotechnology has proven to be an effective countermeasure to tackle the threat of infections. On this note, recent scientific breakthroughs have demonstrated that antimicrobial nanomaterials are effective in preventing pathogens from developing resistance. Despite the ability to destroy a great deal of bacteria and control the outbreak of infections, nanomaterials present many other advantages. Moreover, it is unlikely for nanomaterials to develop resistance due to their multiple and simultaneous bactericidal mechanisms. In recent years, science has explored more complex antimicrobial coatings and nanomaterials based on graphene have shown great potential in antibacterial treatment. The purpose of this article is to deepen the discussion on the threat of infections related to surface disinfection and to assess the state of the art and potential solutions, with specific focus on disinfection procedures using nanomaterials.

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available The database systems have nowadays an increasingly important role in the knowledge-based society, in which computers have penetrated all fields of activity and the Internet tends to develop worldwide. In the current informatics context, the development of the applications with databases is the work of the specialists. Using databases, reach a database from various applications, and also some of related concepts, have become accessible to all categories of IT users. This paper aims to summarize the curricular area regarding the fundamental database systems issues, which are necessary in order to train specialists in economic informatics higher education. The database systems integrate and interfere with several informatics technologies and therefore are more difficult to understand and use. Thus, students should know already a set of minimum, mandatory concepts and their practical implementation: computer systems, programming techniques, programming languages, data structures. The article also presents the actual trends in the evolution of the database systems, in the context of economic informatics.

    The scenario of thermonuclear fusion research is presented, and the tokamak which is the most promising candidate as a fusion reactor is introduced. A brief survey is given of the most noteworthy tokamaks in the global context, and fusion programmes relating to Next Step devices are outlined. Supplementary heating of tokamak plasma by different methods is briefly reviewed; the latest achievements in heating to fusion temperatures are also reported. The progress towards the high value of the fusion product necessary for ignition is described. The improvement in plasma confinement brought about especially by the H-mode, is discussed. The latest situation in pushing up Β for increasing the efficiency of a tokamak is elucidated. Mention is made of the different types of wall treatment of the tokamak vessel for impurity control, which has led to a significant improvement in tokamak performance. Different methods of current drive for steady state tokamak operation are reviewed, and the issue of current drive efficiency is addressed. A short resume is given of the various diagnostic methods which are employed on a routine basis in the major tokamak centres. A few diagnostics recently developed or proposed in the context of the advanced tokamaks as well as the Next Step devices are indicated. The important role of the interplay between theory, experiment and simulation is noted, and the areas of investigation requiring concerted effort for further progress in tokamak research are identified.

    Presentation of suspected pediatric uveitis: Pediatric uveitis is usually managed in specialized ophthalmic centers in the UK. Meaningful data acquisition in these clinics may be helpful in clinical governance, and healthcare planning in a specialty that is gradually changing due to changes in treatment choices. Retrospective analysis of prospectively acquired data in the Liverpool pediatric uveitis database was performed. Analysis of our data, based on 147 patients, with a mean age of 10 years, indicated a female to male ratio of 2:1. 99% of patients were Caucasian. Our data indicates 86% of all patients attending the uveitis clinic were diagnosed with juvenile idiopathic arthritis, followed by intermediate uveitis 5% and idiopathic uveitis 4%. 46% of patients required treatment. Systemic treatment included methotrexate (34%), prednisolone (14%), etanercept (6%), ciclosporin (6%), mycophenolate (3%), and infliximab (1%). Severe visual loss (defined by counting fingers or below vision) was seen in 10 eyes despite appropriately treated chronic uveitis. Our data shows uveitis-related ocular morbidity in a predominantly pediatric Caucasian population. Patients with severe and chronic uveitis may experience significant uveitis-related complications and subsequent visual loss despite aggressive treatment.

    2000-01-01

    United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) was established in 1955. The Committee reviews the exposure of the world population to all sources of radiation under normal circumstances as well as after accidents, and is also the prime international scientific body reviewing and assessing the health risks of exposure to ionizing radiation. Its estimates have been and are still being used by major international bodies including the ICRP, IAEA, and WHO. UNSCEAR's publications form the scientific basis on which international and national agencies develop appropriate radiation protection standards for workers, patients and the general public. UNSCEAR reports yearly to the General Assembly and submits regularly comprehensive reports with detailed scientific annexes on the sources and biological effects of ionizing radiation. In 1995, UNSCEAR began a new program of review of the sources, exposure and biological effects of ionizing radiation. A comprehensive report with scientific annexes will be published in the year 2000. The report will include exposures from natural and man-made radiation sources, occupational and medical radiation exposures, and dose assessment methodologies. The biological effects will cover epidemiological evaluation of radiation-induced cancer, DNA repair and mutagenesis, hereditary effects, combined effects of radiation and other agents, as well as models, mechanisms and uncertainties of biological effects at low radiation doses. An assessment of exposures and effects of the Chernobyl accidents is also made. A brief overview is presented here of the range of subjects considered by the Committee. (author)

    Full Text Available Our understanding of extra-solar planet systems is highly driven by advances in observations in the past decade. Thanks to high precision spectrographs, we are able to reveal unseen companions to stars with the radial velocity method. High precision photometry from the space, especially with the Kepler mission, enables us to detect planets when they transit their stars and dim the stellar light by merely one percent or smaller. Ultra wide-field, high cadence, continuous monitoring of the Galactic bulge from different sites around the southern hemisphere provides us the opportunity to observe microlensing effects caused by planetary systems from the solar neighborhood, all the way to the Milky Way center. The exquisite AO imaging from ground-based large telescopes, coupled with high-contrast coronagraph, captured the photons directly emitted by planets around other stars. In this article, I present a concise review of the extra-solar planet discoveries, discussing the strengths and weaknesses of the major planetary detection methods, providing an overview of our current understanding of planetary formation and evolution given the tremendous observations delivered by various methods, as well as on-going and planned observation endeavors to provide a clear picture of extra-solar planetary systems.

    Gaz de France (GDF) presents in a press kit the main results achieved in 1997. The European community has formulated a project of definition of rules concerning the natural gas market. Minima values for annual consumptions have been defined and the consumption and use of natural gas in EC countries is described. The financial results of GDF in 1997 are compared with previous years. Net sales grew by nearly 1 billion french francs to reach 55 billion. Overall sales were down by 4% but the share of natural gas in french energy consumption increased and sales to industrial users went up in particular due to new cogeneration plants installed in 1996. A comparison of gas prices in Europe is given for the years 1985 to 1998. The efforts of GDF to offer increased quality of services concerning in particular safety aspects as checking programs and installation of new safeguard appliances are described. The efforts of GDF to increase the energy market share of natural gas resulted in the development of new products like cogeneration, air conditioning and fuels for automotive needs. (C.B.)

    The practice of neonatology in Israel debuted in the 1970s as local enterprises by individual hospitals that needed to provide sick and preterm newly born infants with up-to-date and effective care. Descriptions of research and advances in humane and gentle treatment during neonatal care for preterm infants and their families, as well as prevention of neonatal infections, follow-up of preterm infants and care of full-term infants are presented in this issue. The Israel National Very Low Birth Weight (VLBW) Infant database provides an excellent source of knowledge, which has led to multiple scientific publications. Recent international comparisons of the outcome of preterm VLBW infants, made possible by this unique database in Israel, has provided the neonatal community and the Ministry of Health with insights as to the differences in prognosis between Israel and other countries, especially among extremely low birth weight infants. At the border of viability, mortality in Israelis significantly higher than that reported in other countries and proactive steps undertaken to examine these differences and prompt correctional action should be pursued. The Israel Ministry of Health started positive initiatives and should ensure that their steps are implemented at the preterm infant's bedside.

    This report first presents the characteristics of conventional oil and gas system, and the classification of liquid and gaseous non conventional hydrocarbons, with the peculiar case of coal-bed methane. The authors then describe how source rock hydrocarbons are produced: production of shale oils and gases (horizontal drilling, hydraulic fracturing, exploitation) and of coal-bed methane and coal mine methane. In the next part, they address and discuss the environmental impact of source rock hydrocarbon production: installation footprint, water resource management, drilling fluids, fracturing fluids composition, toxicity and recycling, air pollution, induced seismicity, pollutions from other exploitation and production activities. They propose an overview of the exploitation and production of source rock gas, coal-bed gas and other non conventional gases in the world. They describe the current development and discuss their economic impacts: world oil context and trends in the USA, in Canada and other countries, impacts on the North American market, on the world oil industry, on refining industries, on the world oil balance. They analyse the economic impacts of non conventional gases: development potential, stakes for the world gas trade, consequence for gas prices, development opportunities for oil companies and for the transport sector, impact on CO 2 emissions, macro-economic impact in the case of the USA

    1997-01-01

    Major advancements in radiation epidemiology have occurred during the last several years in studies of atomic bomb survivors, patients given medical radiation, and radiation workers, including underground miners. Risks associated with the Chernobyl accident, indoor radon and childhood exposure to I-131 have yet to be elucidated. Situations in the former Soviet Union around Chelyabinsk, a nuclear installation in the southern Urals, and in the Altai, which received radioactive fallout from weapons testing at Semipalatinsk, Kazakhstan, have the potential to provide information on the effects of chronic radiation exposure. Since Roentgen's discovery of x-rays just 100 years ago, a tremendous amount of knowledge has been accumulated about human health effects following irradiation. The 1994 UNSCEAR report contains the latest compilation and synthesis of radiation epidemiology. This overview will cover epidemiology from a radiation perspective. The different types of study methodologies will be described, followed by a kaleidoscope coverage of past and present studies; ending with some remaining questions in radiation epidemiology. This should set the stage for future chapters, and stimulate thinking about implications of the new data on radiation cancer risks

    The case of a 27-year-old Hispanic female who presented with an occipito-parietal tumor after suffering trauma to the area. A physical examination revealed no tenderness to palpation and with evidence of healing ulcerations. The biopsy was consistent with a synovial sarcoma. A wide excision of the mass (15cm x 14cm x 6cm) followed by a pericranial flap was performed. A follow-up CT showed recurrence involving the parietal sagittal sinus. After a second biopsy the mass was determined to be a small-cell sarcoma, consistent with Ewing's sarcoma. Chemotherapy included 8 cycles of doxorubicin, vincristine, and cyclophosphamide, with alternating cycles of etoposide and ifosfamide. A year later, a second wide excision of the mass was performed, followed by bilaminate skin substitute and skin graft placement for reconstruction of the soft-tissue defect. After chemotherapy, a follow-up PET scan showed no signs of re-uptake in any soft tissue or skeletal structures. After 2 years, the patient remains in complete remission.

    Objective: To determine the clinical preparation of primary hypothyroidism at the time of diagnosis. Design: It was an observational and prospective study. Place and Duration of Study: Civil Hospital, Karachi from 1st January 1997 to 31st December 1997. Subjects and Methods: Forty-eight consecutive cases of primary hypothyroidism were included. A detailed history with special emphasis on symptoms and signs was conducted and the findings observed were noted in previously made proforma. Results: Primary hypothyroidism was found to be 5 times more common in female patients, with male to female ratio 1:5, majority of cases (33.33%) were between 41 to 50 years of age. The common symptoms at the time of presentation were tiredness (95.8%), weakness (91.6%), weight gain (85.4%), hoarseness of voice (83.3%), cold intolerance (77.0%) and constipation (75.0%) in patients. Physical signs observed were delayed relaxation of ankle jerk (93.7%), periorbital edema (83.3%), thick tongue (62.5%), goiter (50.0%), dry and coarse skin (47.9%) in patients. Serum, TSH, T4 and T3 were performed in all cases through immunoradiometric technique. Serum TSH was markedly elevated, with normal to reduced T4 and T3 levels in all cases. Conclusion: Primary hypothyroidism was found more common in female than male of the age group 41-50 years. Weakness, tiredness, hoarseness of voice and constipation were the common symptoms noted. The diagnosis is almost certain on clinical grounds if the patient happens to have delayed relaxation of ankle jerks and periorbital puffiness. (author)

    The tragedy of disappearing of Aral Sea is well known to the World. Before and after collapse of Soviet Union, a huge quantity of scientific and popular editions described with grief the situation around the Aral Sea. After the NIS states became independent, World Bank, UNDP, UNEP in proper competition with each other had provided some assessment of the situation through presentation of some small and medium grants, but after 2000, the local population remained alone with own problems. Although on the eyes of the present generation a unique transformation of great water body into deserts took place, the global scientific community did not find forces and financing for real and detail investigation of the processes accompanying the Sea shrinking and land formation. We should acknowledge and give big respect to NATO, later to German Government that through GTZ (now GIZ) - German International Collaboration Agency - and GFZ (Potzdam) paid attention to this area of environment crisis and organized scientific and protective design in the so-called Priaralie - the territory around the drying Sea and delta of the two rivers - Amudarya and Syrdarya. Thank to this assistance, the local specialists in collaboration with limited a number of foreign scientists (N.Aladin, P.Zavialov, Joop de Schutter, Hans Wilps, Hedi Oberhansli) organized significant works for detail socioeconomic, ecological and hydrological assessment situation in Priaralie and on the Aral sea coast. On this base, Ministry of Agriculture and Water resources of Uzbekistan and State Committee of Water resources of Kazakhstan developed a plan of rehabilitation of Amudarya and Syrdarya deltas and started implementation of these projects. If Kazakh water authority moved ahead in wetland restoration faster, a forestation of delta and drying bed of Aral Sea got big success in Uzbek territory. 244 thousands hectares of saxsaul and tamarix were planted for protection of the Priaralie.

    Both good communication and presentation skills on the part of an academic teacher are crucial when trying to generate students' interest in the subject of a lecture. More generally, our task is to share knowledge in the most effective way possible. It is also worth teaching students presentation skills, as today's students are tomorrow's teachers. An engaging presentation is a powerful tool. There are some rules for presenting which I consider worthy of being discussed and taught at a medical university.

    2011-10-01

    To describe the clinical characteristics, staging and presentation of patients with familial exudative vitreoretinopathy (FEVR) in our clinical practice over the last 25 years. Case series, retrospective review. We included 273 eyes of 145 patients. Data collected from charts included gender, gestational age at birth, birthweight, age at presentation, referring diagnosis, family history, prior ocular surgery, and clinical presentation in each eye. Eyes with invasive posterior segment procedures before initial presentation were excluded. Demographics on presentation and clinical staging. Patients were slightly male predominant (57%) with a mean birthweight of 2.80 kg (range, 740 g-4.76 kg), mean gestational age of 37.8 weeks (range, 25-42), and mean age at presentation of almost 6 years (range, presentation, gestational age, and birthweight. Although a positive family history on presentation may support the diagnosis of FEVR, a negative family history is of little help. The majority of retinal folds extended radially in the temporal quadrants, but radial folds were seen in almost all quadrants. Fellow eyes demonstrated a wide variation in symmetry. The presentation of FEVR may mimic the presentation of other pediatric and adult vitreoretinal disorders, and careful examination is often crucial in making the diagnosis of FEVR.

  17. Antigen Cross-Presentation of Immune Complexes

    Platzer, Barbara; Stout, Madeleine; Fiebiger, Edda

    2014-01-01

    The ability of dendritic cells (DCs) to cross-present tumor antigens has long been a focus of interest to physicians, as well as basic scientists, that aim to establish efficient cell-based cancer immune therapy. A prerequisite for exploiting this pathway for therapeutic purposes is a better understanding of the mechanisms that underlie the induction of tumor-specific cytotoxic T-lymphocyte (CTL) responses when initiated by DCs via cross-presentation. The ability of humans DC to perform cross-presentation is of utmost interest, as this cell type is a main target for cell-based immunotherapy in humans. The outcome of a cross-presentation event is guided by the nature of the antigen, the form of antigen uptake, and the subpopulation of DCs that performs presentation. Generally, CD8α+ DCs are considered to be the most potent cross-presenting DCs. This paradigm, however, only applies to soluble antigens. During adaptive immune responses, immune complexes form when antibodies interact with their specific epitopes on soluble antigens. Immunoglobulin G (IgG) immune complexes target Fc-gamma receptors on DCs to shuttle exogenous antigens efficiently into the cross-presentation pathway. This receptor-mediated cross-presentation pathway is a well-described route for the induction of strong CD8+ T cell responses. IgG-mediated cross-presentation is intriguing because it permits the CD8− DCs, which are commonly considered to be weak cross-presenters, to efficiently cross-present. Engaging multiple DC subtypes for cross-presentation might be a superior strategy to boost CTL responses in vivo. We here summarize our current understanding of how DCs use IgG-complexed antigens for the efficient induction of CTL responses. Because of its importance for human cell therapy, we also review the recent advances in the characterization of cross-presentation properties of human DC subsets. PMID:24744762

    2012-02-01

    The mode of presentation of coeliac disease has been changing to more atypical or silent disease. Few studies described the clinical presentation of adult coeliac disease in Ireland in recent years. We retrospectively collected the clinical data for all patients who had a diagnosis of coeliac disease made in our centre between January 07 and December 08. Forty seven adults, predominantly females (n = 30), had a confirmed diagnosis of coeliac disease made during the study period. In our patient cohort, the presenting symptom was diarrhoea in 19 (40%) patients, while 16 patients (34%) did not have any G.I. symptoms, 10 (21%) presented with anaemia. Females presented at a significantly younger age compared to males, with median ages at diagnosis of 44.5 and 57 years, respectively (p = 0.04). Females also presented more commonly with non G.I. symptoms (p = 0.07). The reasons behind this gender difference need further study.

Slides are used in various designated areas: promotional presentations at meetings as a form of communication between participants and also as visual presentation of lecture material content of the report. It was found that a human catches up and remembers only about 10% of what he has read, 20% of what he has heard and even 50% of what he heard and saw. Therefore, high-quality and Professional presentation of information in the slide form has a significant impact on the uptake. The authors present a solution how to present the study material qualitatively and use the media system effectively for teaching computer graphics course. This course is taught for VGTU first or second year students of almost all specialities. This presentation of study materials facilitates the teacher's work and improves the readability and solutions of study materials.

    Lindsay, R C; Lea, J A; Nosworthy, G J; Fulford, J A; Hector, J; LeVan, V; Seabrook, C

    1991-12-01

    Biased lineups have been shown to increase significantly false, but not correct, identification rates (Lindsay, Wallbridge, & Drennan, 1987; Lindsay & Wells, 1980; Malpass & Devine, 1981). Lindsay and Wells (1985) found that sequential lineup presentation reduced false identification rates, presumably by reducing reliance on relative judgment processes. Five staged-crime experiments were conducted to examine the effect of lineup biases and sequential presentation on eyewitness recognition accuracy. Sequential lineup presentation significantly reduced false identification rates from fair lineups as well as from lineups biased with regard to foil similarity, instructions, or witness attire, and from lineups biased in all of these ways. The results support recommendations that police present lineups sequentially.

    The encoding and representation of visually presented clock times was investigated in three experiments utilizing a comparative judgment task. Experiment 1 explored the effects of comparing times presented in different formats (clock face, digit, or word), and Experiment 2 examined angular distance effects created by varying positions of the hands on clock faces. In Experiment 3, encoding and processing differences between clock faces and digitally presented times were directly measured. Same/different reactions to digitally presented times were faster than to times presented on a clock face, and this format effect was found to be a result of differences in processing that occurred after encoding. Angular separation also had a limited effect on processing. The findings are interpreted within the framework of theories that refer to the importance of representational codes. The applicability to the data of Bank's semantic-coding theory, Paivio's dual-coding theory, and the levels-of-processing view of memory are discussed.

    Full Text Available Aim. We aim to describe a female patient with Menkes disease who presented with epilepsia partialis continua. Case Presentation. Seventeen-months-old Saudi infant was presented with repetitive seizures and was diagnosed to have epilepsia partialis continua. Discussion. Menkes disease (OMIM: 309400 is considered a rare, X-linked recessive neurodegenerative disorder resulting from a mutation in the gene coding for the copper transporting ATPase (ATP7A. Affected individuals usually present with kinky hair, skeletal changes, prolonged jaundice, hypothermia, developmental regression, decreased tone, spasticity, weakness, and therapy resistant seizures. Conclusion. Raising awareness of abnormal presentation of this rare disease may help in the control of seizures through subcutaneous copper supplementation.

  15. Intracellular events regulating cross-presentation

    Full Text Available Cross-presentation plays a fundamental role in the induction of CD8-T cell immunity. However, although more than three decades have passed since its discovery, surprisingly little is known about the exact mechanisms involved. Here we give an overview of the components involved at different stages of this process. First, antigens must be internalized into the cross-presenting cell. The involvement of different receptors, method of antigen uptake, and nature of the antigen can influence intracellular trafficking and access to the cross-presentation pathway. Once antigens access the endocytic system, different requirements for endosomal/phagosomal processing arise, such as proteolysis and reduction of disulfide bonds. The majority of cross-presented peptides are generated by proteasomal degradation. Therefore, antigens must cross a membrane barrier in a manner analogous to the fate of misfolded proteins in the endoplasmic reticulum (ER that are retrotranslocated into the cytosol for degradation. Indeed, some components of the ER-associated degradation (ERAD machinery have been implicated in cross-presentation. Further complicating the matter, endosomal and phagosomal compartments have been suggested as alternative sites to the ER for loading of peptides on MHC class I molecules. Finally, the antigen presenting cells involved, particularly dendritic cell subsets and their state of maturation, influence the efficiency of cross-presentation.

  16. Information presentation in power plant control rooms

    International Nuclear Information System (INIS)

    Kautto, A.

    1984-11-01

    The objective of this study is to support operators' work especially in the control rooms of power plant. The exemplified process is a pressurized water (nuclear) reactor (PWR). The man-process interface is an information system that covers information refining, information presentation, information system handling, and process control. THe emphasis in this study is on the organization and presentation of information and on the alert function that is part of the information system. Another goal is to design the alert function so as to radically reduce the number of alarms during plant shutdown, e.g. during the refuelling or maintenance period and during a disturbance. Further, the experimental validation of CFMS (Critical Function Monitoring System), developed by Combustion Engineering, Inc. in the U.S.A. is described briefly. The validation was made at the Loviisa training simulator in the autumn of 1982. CFMS is a safety-related functional alarm system. The functional decomposition of information has turned out to be successful and it is helpful in designing displays. Preliminary criteria for designing displays, the structure of the information presentation system and the illustration of main interactions are presented. General practical ideas on designing the alert function seem very promising. Preliminary results of the CFMS validation are presented. Further, some ideas are presented on how to carry out the analysis and how to make such validations in the future. A new idea for the evaluation of core safety is presented, based on control theory concepts

    1997-03-01

    Separate, extended series of positive, negative, and neutral pictures were presented to 24 (12 men, 12 women) undergraduates. Each series was presented on a different day, with full counterbalancing of presentation orders. Affective state was measured using (a) orbicularis oculi activity in response to acoustic startle probes during picture presentation, (b) corrugator supercilii activity between and during picture presentation, and (c) changes in self-reports of positive and negative affect. Participants exhibited larger eyeblink reflex magnitudes when viewing negative than when viewing positive pictures. Corrugator activity was also greater during the negative than during the positive picture set, during both picture presentation and the period between pictures. Self-reports of negative affect increased in response to the negative picture set, and self-reports of positive affect were greatest following the positive picture set. These findings suggest that extended picture presentation is an effective method of manipulating affective state and further highlight the utility of startle probe and facial electromyographic measures in providing on-line readouts of affective state.

    Publication in scientific journals is required for academic promotion at universities. It is also the method by which most family medicine faculty members disseminate their scholarly work, establish a reputation in their field, and develop a clinical, teaching, or scholarly expertise. Publications are able to reach a broader audience than are presentations, which makes them the epitome of academic scholarship. Most academic family physicians give presentations to students, residents, or colleagues as part of their regular job duties and at regional and national meetings, but few write articles based on those presentations.

    2012-12-01

    Full Text Available Hemophagocytic lymphohistiocytosis (HLH is a rare life-threatening condition. Uncontrolled proliferation of activated lymphocytes secreting high amounts of inflammatory cytokines seems to be the main pathogenesis. The diagnosis of HLH can often be difficult. It may presents in many forms such as fever of unknown origin, hepatitis, acute liver failure, and sepsis-like illness. Here we present a newborn galactosemia case presented with HLH. Close monitoring of the diagnostic criteria of HLH during the course of galactosemia-associated hemophagocytosis, both before and after dietary treatment, should be performed in order to fully determine if the triggering mechanism is infection or accumulation of metabolites.

  1. Gynaecomastia as the initial presentation of thyrotoxicosis

    Directory of Open Access Journals (Sweden)

    Triranjan Sanyal

    2012-01-01

    Full Text Available Gynaecomastia is a well-recognized manifestation of thyrotoxicosis occurring in a widely variable percentage. Some studies have reported the percentage to be high as 40% while others report it being around 10%. The variation can be attributed to the difference in the criteria used to define gynae-comaslia or racial factors. However, thyrotoxicosis presenting with gynaceomastia as an intial manifestation is very rare. Only handful case reports are found in literature. Here we present a case of 35-year-old Indian male, with thyrotoxcosis who presented initially with painful bilateral gynaceomastia.

    Moxibustion, a form of traditional Chinese medicine (TCM), is the burning of the herb moxa (Folium Artemisiae argyi or mugwort) over acupuncture points. It is often used in China to facilitate cephalic version of breech presentation. This article reviews the history, philosophy, therapeutic use, possible mechanisms of action, and literature pertaining to its use for this indication. For moxibustion, moxa can be rolled into stick form, placed directly on the skin, or placed on an acupuncture needle and ignited to warm acupuncture points. Studies have demonstrated that moxibustion may promote cephalic version of breech presentation and may facilitate external cephalic version. However, there is currently a paucity of research on the effects of moxibustion on cephalic version of breech presentation, and thus there is a need for further studies. Areas needing more investigation include efficacy, safety, optimal technique, and best protocol for cephalic version of breech presentation. © 2018 by the American College of Nurse-Midwives.

    When, at the turn of the century, public electric power supply facilities were created and in 1908, the electric power stations of the Swiss canton of Zurich (EKZ) were built, only a third of the communities in the Zurich area could boast about being the consumers of this new energy. But what did the first electrically powered devices and machines look like? This, and more, is presented in the ''electric power house'' in Burenwisen Glattfelden in the canton of Zurich. Besides a Kaplan turbine and a sample of the most interesting devices from the past and the present, the focus of the exhibition is on the presentation of the new and old sources of light. The EKZ are pleased to be able to present their ''electric power house'' to the public, providing a broad range of information on energy-related questions and the development of electric power supply.

    Full Text Available Gonococcus typically affects the mucosal surfaces but in rare cases can spread to bloodstream causing disseminated gonococcal infection (DGI. The usual presentation of DGI is rash, polyarthralgia, and tenosynovitis. We present the case of a 23-year-old female who presented to our hospital with pustular rash and tenosynovitis of hand and was sent home on Augmentin. Her symptoms worsened despite treatment and she presented back to the ED. On investigation, she was found to have DGI and was appropriately treated. DGI should be kept in mind in sexually active youngsters who have only one or two features of the classic triad of rash, tenosynovitis, and arthritis. Timely management and appropriate treatment of DGI is very important to avoid complications and morbidity.

    Full Text Available Melanoacanthoma is very rare variant of seborrheic keratosis presenting as a deeply pigmented benign proliferation of melanocytes and keratinocytes usually presenting over the head, neck and trunk of elderly people. A sixty-two-years-old male was presented with a solitary slow growing asymptomatic hyperpigmented verrucous outgrowth with cerebriform surface measuring 15 cm by 8 cm present over the left inguinal region extending on to the scrotum since past 8 years. There was no associated lymphadenopathy. The histopathology revealed hyperkeratosis, papillomatosis, acanthosis with presence of melanocytes at all levels of epidermis with abundant melanin giving the diagnosis of melanoacanthoma. The patient further underwent surgical excision of the lesion. The case is being reported for its rarity, unusual location, massive size and clinical resemblance to a verrucous carcinoma.

    2014-05-01

    Presence of posterior urethral valves (PUV) is the most common cause of urinary tract obstruction in the male neonate. Late presentation occurs in 10% of cases. We present a case of PUVs in an adult male who presented with history of obstructive lower urinary tract symptoms and hematuria. On evaluation, he was found to have raised serum creatinine level. A voiding cystourethrogram (VCUG) could not be completely performed because of narrowing in the posterior urethra. A rigid urethrocystoscopy was performed at which he was found to have type-I posterior urethral valve which were fulgurated. A repeat uroflowmetry revealed maximum flow rate of 12 ml/second. This case highlights that PUVs is not solely a disease of infancy but may also present late. VCUG is the radiological investigation of choice but the diagnosis may be missed. A urethrocystoscopy is advised if there is a high index of suspicion.

    Full Text Available Supplementing traditional chalk and board instruction with computer delivery has been viewed positively by students who have reported increased understanding and more interaction with the instructor when computer presentations are used in the classroom. Some problems contributing to student errors while taking class notes might be transcription of numbers to the board, and handwriting of the instructor can be resolved in careful construction of computer presentations. The use of computer presentation programs promises to increase the effectiveness of learning by making content more readily available, by reducing the cost and effort of producing quality content, and by allowing content to be more easily shared. This paper describes how problems can be overcome by using presentation packages for instruction.

    Accidental ingestion is an important preventable cause of childhood morbidity. All accidental ingestion presentations (n = 478) to a tertiary paediatric ED from January 2010 to December 2011 were analysed. These results were compared with a similar study in the same institution ten years previously in 2001 and showed that while accidental ingestions constituted a higher proportion of presentations (0.5% in this study v 0.45% in 2001), fewer had investigations performed (21% v 35%) and fewer were admitted (7% v 20%). Accidental ingestions account for 0.5% of presentations and are an important focus of home safety information for parents and guardians. Paracetamol (n = 67, 14%) and liquid detergent capsules (n = 44, 9.2%) were the two most common substances implicated in these presentations, and have the potential to cause severe morbidity and mortality.

    Glomus tumours are benign, soft tissue tumours, usually of fingertips. Classically they present with severe pain, temperature sensitivity and localised tenderness. The diagnosis is often delayed due to sometimes non-specific symptoms and rarity of the disorder. While usually a clinical diagnosis, imaging may be necessary for diagnosis and localisation. We present a case of glomus tumour of the fingertip with an unusual history.

    Present detectors for digital radiography are of two classes: real time detectors and storage (non real time) types. Present real time detectors consist of image intensifier tubes with an internal cesium iodide layer x-ray converter. Non real time detectors involve linear sweep arrays or storage detectors such as film. Future detectors discussed here can be of both types utilizing new technologies such as hydrogenated amorphous silicon photodiode arrays coupled to thin film transistor arrays. 17 refs., 10 figs

    Objective was to describe the clinical features of 5 patients with rare atypical presentation of idiopathic intracranial hypertension (IIH), and propose the possible mechanism of this atypical presentation. We carried out a retrospective study of 5 patients, admitted at King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia with IIH during the period from January 2001 to December 2005. All were females with their age ranges from 24 to 40 years. The clinical presentations, the laboratory and imaging studies were analyzed. The opening pressures of the lumbar puncture tests were documented. All patients were presented with headache. One had typical pain of trigeminal neuralgia and one with neck pain and radiculopathy. Facial diplegia was present in one patient and two patients had bilateral 6th cranial neuropathy. Papilledema was present in all patients except in one patient. Imaging study was normal in all patients, and they had a very high opening pressure during lumbar puncture, except in one patient. All patients achieved full recovery with medical therapy in 6 to 12 weeks with no relapse during the mean follow up of 2 years. Atypical finding in IIH are rare and require a high index of suspicion for early diagnosis. (author)

    Full Text Available Abstract Background We highlight the orbital manifestations of acute myeloid leukemia and the role of peripheral blood smear in the diagnosis of these cases. A total of 12 patients who presented with proptosis and were subsequently diagnosed to have acute myeloid leukemia based on incision biopsy or peripheral blood smear were included in the study. Results A retrospective review of all cases of acute myeloid leukemia presenting to the Orbital clinic was performed. The age at presentation, gender, presenting features, duration of symptoms and fundus features were noted. In addition the temporal relationship of the orbital disease to the diagnosis of leukemia, laterality, location of the orbital mass, imaging features and the diagnostic tools used to diagnose leukemia were noted. The median age at presentation was 6 years. The male: female ratio was 0.7:1. None of these patients had been diagnosed earlier as having acute myeloid leukemia. The presenting features included proptosis in all patients, orbital mass in 5 (41.7%, visual symptoms in 2 (16.7% and subconjunctival hemorrhage in one patient (8.3%. A diagnosis of acute myeloid leukemia was established by incision biopsy in 4 patients, subsequently confirmed by peripheral blood smear testing and bone marrow biopsy in 2 patients which revealed the presence of systemic involvement. Imprint smears of the biopsy identified blasts in 2 of 4 cases. In 8 patients presenting with ocular manifestations, diagnosis was established by peripheral blood smear examination alone which revealed a diagnosis of acute myeloid leukemia. Conclusion A peripheral blood smear should be performed in all cases of sudden onset proptosis or an orbital mass in children and young adults along with an orbital biopsy. It can always be complemented with a bone marrow biopsy especially in cases of aleukemic leukemia or when the blood smear is inconclusive.

    To study the clinical profile and presentation of children with unilateral cataract. In this hospital-based, observational, cross-sectional study, patients 15 years of age or younger who presented with unilateral cataract were recruited. Cases of cataract secondary to causes such as trauma or uveitis were excluded. Age at detection and presentation, distance from the treatment center, presenting complaints, cataract morphology, and biometry were noted for each case. A total of 76 patients were recruited. Most patients presented with complaints of leukocoria. Persistent fetal vasculature accounted for 27.6% of cases and was the most common identifiable cause of cataract in this study. Subsequently, patients were divided into two groups: no persistent fetal vasculature (control) and persistent fetal vasculature. A male predominance was noted in both groups. The mean age at detection was 27.58 ± 37.02 and 6.17 ± 8.42 months and the mean age at presentation was 55.613 ± 45.21 and 14.83 ± 17.75 months in the control and persistent fetal vasculature groups, respectively. In the persistent fetal vasculature group, a significant difference was noted in the axial length, keratometry, and corneal diameter between the affected and normal eyes (P = .027, .00176, and .0114, respectively). In the control group, this difference was observed only in keratometry readings (P = .0464). The mean distance traveled by patients to reach the treatment center was 211 km. Persistent fetal vasculature is an important and less identified cause of unilateral cataract. A significant delay is noted in the detection and presentation of unilateral cataract.

    Full Text Available The making of presentations has become an omnipresent act of communication in the companies practice, but also in the didactic one. The notoriety and the increase of the importance of an efficient presentation lie in the transformations felt by a society of knowledge, communication being the answer in front of a constant information wave.Business people look in fear at the preparation of a presentation, the interaction with the audience andtheir feedback, all these leading to a low efficiency in transmitting the message.The speaker must overcome a group of obstacles, the most important being the reduced human capacityto capture the information transmitted orally; in this respect, he has available a group of visual instruments and strategies to capture the attention. In order to achieve efficiency one needs mental and emotional preparation, knowing the audience and the presentation’s objective and eliminating the old listing format in PowerPoint, for focusing the communication of the audience’s necessities. The present essay aims to analyze the verbal, non-verbal and para-verbal communication act that constitutes the base of any presentation, the reasons that lead to failure and the ways to increase efficiency, in order to succeed in transmitting a well structured and easy to remember message.Many researchers and practice workers within the communication, economic but also IT fields, have tried to find the solution for organizing and transmitting the message during a presentation, in accordance with the new technologies. In elaborating the present paper, we have used our personal experience and data obtained through 30 in-depth interviews,with managers in companies such Bostina Asociatii Skoda, Petrom etc.; we have used in our research articles of honored professors in social sciences from the Harvard and Stanford Universities , researches of the Minnesota and Ulster Universities, as well as works of specialists in marketing and information

    Objectives: To study the outcome of intestinal tuberculosis presenting as acute abdomen. Study design: Descriptive Study. Place and Duration: Bolan Medical Complex Hospital (BMC) Quetta and Combined Military Hospital (CMH) Quetta from Nov 2003 to Nov 2005 from Bolan Medical Complex and from Nov 2005 to Nov 2006 in CMH Quetta. Material and Method: Thirty seven patients of acute abdomen presenting with intestinal obstruction were admitted; 28 from emergency department and 9 from out patient department. Twenty seven patients were from BMC and 10 from CMH Quetta. Patients were diagnosed as having abdominal tuberculosis on the basis of operative findings and histopathological reports. Results: Out of 37 patients presenting with acute abdomen due to intestinal obstruction, 54% were male and 46% were female with M: F ratio of 1: 1.2. Age of the patient ranged from 20 to 50 years, with maximum frequency between 30 to 40 years. Abdominal pain was the commonest presenting feature in all patients followed by constipation in 81.1% patients. Peritonism was seen in 27% patients. Different operative procedures performed were adhesionolysis 65.8%, segmental resection 7.9%, right hemicolectomy 10.5%, stricturoplasty 7.9% and ileostomy 1.3%. Mesenteric lymph node biopsy 40.8%. Conclusion: Intestinal tuberculosis is still a very important surgical problem in our country presenting as acute abdomen. A suspicion must always be kept during laparotomy and adequate tissue histopathology should supplement the diagnosis. (author)

    1988-01-01

    A description is given of user interface research aimed at bringing together multiple input and output modes in a way that handles mixed mode input (commands, menus, forms, natural language), interacts with a diverse collection of underlying software utilities in a uniform way, and presents the results through a combination of output modes including natural language text, maps, charts and graphs. The system, Integrated Interfaces, derives much of its ability to interact uniformly with the user and the underlying services and to build its presentations, from the information present in a central knowledge base. This knowledge base integrates models of the application domain (Navy ships in the Pacific region, in the current demonstration version); the structure of visual displays and their graphical features; the underlying services (data bases and expert systems); and interface functions. The emphasis is on a presentation planner that uses the knowledge base to produce multi-modal output. There has been a flurry of recent work in user interface management systems. (Several recent examples are listed in the references). Existing work is characterized by an attempt to relieve the software designer of the burden of handcrafting an interface for each application. The work has generally focused on intelligently handling input. This paper deals with the other end of the pipeline - presentations.

    Myasthenia gravis (MG) is an autoimmune disorder presenting with fluctuating, fatigable muscle weakness. Initial symptoms classically involve ocular and proximal limb muscles. Rarely, MG may onset with unusual features, so it can be misdiagnosed with other neuromuscular diseases. To describe unusual and atypical presentations of MG in a large cohort of patients, considering and discussing diagnostic difficulties and pitfalls. We report on 21 out of 508 MG patients, coming to our department in the last 27 years and presenting with atypical or unusual features. The diagnosis was achieved performing a careful clinical examination, a proper neurophysiological assessment, the neostigmine test, the AChR and MuSK antibodies assay and chest CT-scan. Patients with atypical/unusual MG onset were the 4.4% of all MG patients population. We describe seven different clinical categories: asymmetric distal upper limbs weakness, foot drop, isolated triceps brachii weakness and foot drop, post exertional axial weakness with dropped head, acute facial dyplegia, limb-girdle MG and MG with sudden lower limbs weakness and recurrent falls. Atypical and unusual presentations may increase the risk to misdiagnose or delay MG diagnosis. Isolated limb-girdle presentation is the most frequent atypical form in our series.

    Scientific and educational poster presentations in national and international meetings are one of the most effective means of scientific communication. Poster presentations are of particular importance in a mainly visual speciality like radiology, and also play a significant role in continuing medical education in our specialty. However, poster should be no more than an intermediate step on the way to publish our work in a scientific journal. The publication rates of posters prented in courses and conferences is very low in our country. Therefore, we must continue to progress in training in scientific publication, with efforts such as this supplement. This article review how to create an effective poster presentation.

    Moxibustion (a type of Chinese medicine which involves burning a herb close to the skin) to the acupuncture point Bladder 67 (BL67) (Chinese name Zhiyin), located at the tip of the fifth toe, has been proposed as a way of correcting breech presentation. To examine the effectiveness and safety of moxibustion on changing the presentation of an unborn baby in the breech position, the need for external cephalic version (ECV), mode of birth, and perinatal morbidity and mortality for breech presentation. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (26 March 2012), MEDLINE (1966 to 1 August 2011), EMBASE (1980 to August 2011), CINAHL (1982 to 1 August 2011), MIDIRS (1982 to 1 August 2011) and AMED (1985 to 1 August 2011) and searched bibliographies of relevant papers. The inclusion criteria were published and unpublished randomised controlled trials comparing moxibustion (either alone or in combination with acupuncture or postural techniques) with a control group (no moxibustion), or other methods (e.g. external cephalic version, acupuncture, postural techniques) in women with a singleton breech presentation. Two review authors independently assessed eligibility and trial quality and extracted data. The outcome measures were baby's presentation at birth, need for external cephalic version, mode of birth, perinatal morbidity and mortality, maternal complications and maternal satisfaction, and adverse events. Six new trials have been added to this updated review. One trial has been moved to studies awaiting classification while further data are being requested. This updated review now includes a total of eight trials (involving 1346 women). Meta-analyses were undertaken (where possible) for the main and secondary outcomes. Moxibustion was not found to reduce the number of non-cephalic presentations at birth compared with no treatment (P = 0.45). Moxibustion resulted in decreased use of oxytocin before or during labour for women who had vaginal

    Full Text Available Cash flow analysis is one of the most popular methods for investigating the outcome of an economical project. The costs and benefits of a construction project are often involved with uncertainty and it is not possible to find a precise value for a particular project. In this paper, we present a simple method to calculate the net present value of a cash flow when both costs and benefits are given as triangular numbers. The proposed model of this paper uses Delphi method to figure out the fair values of all costs and revenues and then using fizzy programming techniques, it calculates the fuzzy net present value. The implementation of the proposed model is demonstrated using a simple example.

    Full Text Available Metabolic syndrome represents a sum of risk factors that lead to the occurrence of cardiovascular and cerebrovascular events. The early detection of metabolic syndrome is extremely important in adults who are at risk. Although the physiopathological mechanisms of the metabolic syndrome are not yet clear, insulin resistance plays a key role that could explain the development of type 2 diabetes mellitus in untreated metabolic syndrome patients. Here, we present the case of a 26-year-old male who was diagnosed with metabolic syndrome and severe hypertriglyceridemia after presenting with abdominal pain. Although hypertriglyceridemia and hyperglycemia are the most common predictors of metabolic syndrome, clinicians need to be vigilant for unexpected presentations in patients at risk for metabolic syndrome. This case sheds light on the importance of early detection.

    2008-01-01

    Full Text Available A 24-year-old male presented with an inability to walk after a trivial fall. He had pain and mild swelling anterior to the right knee for the past one year. X-ray showed a transverse fracture of patella with a lytic lesion occupying most of the two halves of the patella. Fine needle aspiration cytology (FNAC of the lytic lesion revealed a few osteoclastic giant cells and occasional osteoblasts against a hemorrhagic background. Patellectomy was performed. Histology revealed trabecular bone admixed with proliferating chondroid tissue at places admixed with myxoid and fibrous tissue with focal areas of calcification suggestive of chondroblastoma. Focal areas showed osteoclastic giant cells with areas of hemorrhage. The purpose is to present a rare tumor occurring at an unusual site which presented as pathological fracture.

    Full Text Available Erythema elevatum diutinum is a rare chronic leukocytoclastic vasculitis of unknown etiology. Lesions are usually asymptomatic, although burning and itchiness can occur. The typical clinical presentation is characterized by persistent, symmetrical, papules and nodules that may coalesce to form larger nodules or plaques. It may be associated with various pathologies and the diagnosis is based on clinical and histopathological findings. Treatment is based on the use of dapsone and sulfonamides, first-line therapies, and other options such as niacinamide, tetracycline, colchicine, chloroquine and corticosteroids. We describe the case of a 65-year-old male patient that presented a single lesion on the dorsum of the hand, an unusual clinical presentation.

    To report a case of primary antiphospholipid syndrome presenting with isolated homonymous superior quadrantanopsia. A 50-year-old Korean man presented with subjective visual disturbance for 1 month. Visual field testing showed a right homonymous superior quadrantanopsia. Brain magnetic resonance imaging (MRI) revealed an old infarct in his left occipital lobe and multiple lesions in other areas of the brain. Laboratory tests showed a marked increase in serum anti-β2 glycoprotein I antibody, which remained elevated after 12 weeks. He was diagnosed with primary antiphospholipid syndrome and started anticoagulation therapy. This is the first case report of primary antiphospholipid syndrome presenting with isolated homonymous quadrantanopsia. Antiphospholipid syndrome should be considered as a differential diagnosis in patients with homonymous visual field defects accompanying multiple cerebral infarcts.

  14. Ancient engineers' inventions precursors of the present

    Rossi, Cesare

    2017-01-01

    This book describes the inventions and designs of ancient engineers who are the precursors of the present. The period ranges mainly from 300 B.C. to 1600 A.D. with several exceptions. Many of the oldest inventions are documented by archaeological finds, often very little known, mainly from Pompeii, Herculaneum and Stabiae and reveal a surprising modernity in their conception. Most of the inventions presented in the first four parts of the book were conceived up to the late Roman Empire and may be considered as milestones, each in their respective field. The fifth part concentrates on more recent centuries. The sixth part deals with some building construction techniques. Generally, for each of the presented inventions, three elements of research and reference are provided: written documents (the classics), iconic references (coins, bas-reliefs, etc.) and archaeological findings. The authors did not write this book for engineers only; hence they describe all the devices without assuming wide technical knowledge...

    Udayakumar N

    2006-01-01

    Full Text Available A young man who presented with fever, altered sensorium and sudden onset tachypnea, is described. Arterial blood gas analysis, revealed the presence of severe high anion gap metabolic acidosis, with compensatory respiratory alkalosis and normal oxygen saturation. A detailed neurological, nephrological, biochemical and hematological evaluation, revealed the presence of Acute myeloid leukemia, with lactic acidosis and hyponatremia. There are very few reports of presentation of leukemia as lactic acidosis. This case report highlights the need for emergency room physicians, to consider the possibility of lactic acidosis, as one of the causes of high anion gap acidosis and to meticulously investigate the cause of lactic acidosis. We describe a rare clinical instance of lactic acidosis as the presenting manifestation of Acute myeloid leukemia.

    2015-01-01

    Introduction: amoebic hepatic abscess is the extraintestinal manifestation of an infection by entamoeba histolytica. Estimations are made that 10% of the world population has been infected by the parasite, being more frequent in tropical regions, where overcrowding and bad sanitary conditions occur. Africa, Latin America, Southeast Asian and India have considerable health problems, resulting from this disease. In Cuba amoebiasis has been proved not to be one of the most frequent parasitism cases. Case presentation: male patient of age 48 years and of Indian nationality, presenting clinical findings, which proves a unique lesion in the right liver lobule, diagnosed by ultrasound scan and nuclear magnetic resonance. The presence is confirmed of serum antibodies against entamoeba histolytica. Treatment with metronidazole produced clinical and radiological improvement. Conclusions: atypical clinical presentation constitutes a remarkable element worthy considered in daily clinical practice. (author)

  17. Presentation of lipid antigens to T cells.

    Mori, Lucia; De Libero, Gennaro

    2008-04-15

    T cells specific for lipid antigens participate in regulation of the immune response during infections, tumor immunosurveillance, allergy and autoimmune diseases. T cells recognize lipid antigens as complexes formed with CD1 antigen-presenting molecules, thus resembling recognition of MHC-peptide complexes. The biophysical properties of lipids impose unique mechanisms for their delivery, internalization into antigen-presenting cells, membrane trafficking, processing, and loading of CD1 molecules. Each of these steps is controlled at molecular and celular levels and determines lipid immunogenicity. Lipid antigens may derive from microbes and from the cellular metabolism, thus allowing the immune system to survey a large repertoire of immunogenic molecules. Recognition of lipid antigens facilitates the detection of infectious agents and the initiation of responses involved in immunoregulation and autoimmunity. This review focuses on the presentation mechanisms and specific recognition of self and bacterial lipid antigens and discusses the important open issues.

  18. Neglected Alkaptonuric Patient Presenting with Steppage Gait

    2016-04-01

    Full Text Available Even though intervertebral disc degeneration can be found in the natural course of alkaptonuria, detection of the disease by black disc color change in a patient without any other presentation of alkaptonuria is an exceptionally rare condition. We have reported a very rare case of alkaptonuria presented with low back pain and steppage gait in a 51-year-old male with a complaint of chronic low-back pain and steppage gait who was operated on for prolapsed lumbar disc herniation. Intraoperatively his lumbar disk was discovered to be black. The alkaptonuria diagnosis was considered after histopathological examination of the black disc material and elevated urinary concentration of homogentisic acid confirmed the diagnosis. To our knowledge, this presentation has not been reported previously in literature.

    2009-01-01

    Volvulus of the splenic flexure is very rare cause of colonic obstruction constituting 2% of cases of colonic segmental volvulus. Primary splenic flexure volvulus (SFV) is due to congenital absence or laxity of the phrenocolic, gastro colic, and splenocolic ligaments while secondary volvulus is due to other causes including some prior surgery releasing these ligaments. A preoperative diagnosis can be established based on the characteristic radiological findings on plain x-ray abdomen and CT scan. We present a case of SFV in a young man who presented with acute abdominal pain, and distension, and illustrate the usefulness of CT scan, and plain x-ray of the abdomen in making a preoperative diagnosis. Laparotomy revealed a gangrenous SFV, which was resected and primary anastomosis was carried out. Literature is reviewed with regards to predisposing factors, presentation, investigation, and management among the more than 32 cases reported so far. (author)

    Directory of Open Access Journals (Sweden)

    Kathleen Frances Parthe

    2014-11-01

    Full Text Available A close reading of the journalism, correspondence, and memoirs of Alexander Herzen (1812–1870 yields a finely tuned relationship to past, present, and future, but not a complete philosophy of history. Herzen described no system, but repeated key metaphors (e.g., the libretto and concepts (e.g. contingency that reflected his understanding of the historical process. For Herzen, history became interesting when it was relieved of predetermined plots and algebraic formulas. However much he studied Russia’s past and planned its future, his preference was for the present, where freedom is most fully experienced in debate and in the need to choose a path forward. He understood the instrumentality of history in how the lives of ordinary people were affected, which remained his measure of progress. Herzen was a “historian of the present,” and his insights are remarkably applicable to twenty-first-century Russia.

    2007-01-01

    Endometriosis is the presence of ectopic endometrial tissue that responds to hormonal stimulation. Although endometriosis occurs most often in the pelvis, several unusual sites have been reported. We present a case of endometriosis mimicking, a psoas abscess. A 39-year-old lady presented around the right hip, of 5 years duration. Computed tomography (CT) scan showed a multi-loculated mass in the right iliopsoas muscle. On exploration, a hemorrhagic cystic mass was seen pressing on the femoral nerve. The lesion was excised and histological examination of the tissue showed features of endometriosis. The patient was treated by cyclic hormonal suppressive therapy for 3 months. Her pain and flexion deformity of the hip resolved completely. Retroperitoneal endometriosis presenting with deformity and pain in the hip may mimic a psoas abscess. If the possibility of this diagnosis is entertained, inappropriate treatment may be avoided.

    2014-02-01

    Full Text Available Mosquito repellents contain pyrethroid derivatives, as the active ingredient. Data regarding human toxicity following oral intake is limited. This is a case report of an individual who presented with neurotoxicity following oral ingestion of prallethrin (2.4% w/w of a higher concentration present in formulations commercially available than previously. A 22 year old male presented to the emergency Room (ER in status epilepticus. He was managed in the Intensive Care Unit (ICU. No cause for his status could be determined after all laboratory investigations. A review of history with the patient revealed that he had ingested a bottle of liquid mosquito repellent (45 ml. The patient has had no further symptoms on follow up and has been off anti epileptics. Pyrethroid containing mosquito repellents act on neuronal sodium channels causing hyperexcitiability. With no known specific antidotes, symptomatic treatment is the main stay of management.

  3. Cancer presenting during pregnancy: radiological perspectives

    Doyle, S.; Messiou, C.; Rutherford, J.M.; Dineen, R.A.

    2009-01-01

    Malignancy presenting during pregnancy is rare. When it does, there are important considerations and challenges for the radiologist. The physiological changes of pregnancy may mask signs and symptoms of malignancy leading to delayed presentation. Endocrine and physiological changes during pregnancy can interact with tumour biology to alter the behaviour and patterns of growth of certain tumours. The timing and choice of imaging technique pose potential risks to the foetus, but this must be weighed against the risks to both mother and foetus of inadequate investigation or misdiagnosis. This review outlines the general principles and approach to imaging the pregnant patient with suspected malignancy, following which there is a more detailed discussion of the effects of pregnancy on tumour biology and presentation of specific tumours. Imaging strategies are discussed for the different entities, and where possible, evidence-based imaging recommendations are made.

    Darier's disease, also known as keratosis follicularis or dyskeratosis follicularis, is a rare disorder of keratinization. It is an autosomal dominant genodermatosis with high penetrance and variable expressivity. Its manifestation appears as hyperkeratotic papules, primarily affecting seborrheic areas on the head, neck, and thorax and less frequently on the oral mucosa. When oral manifestations are present, the palatal and alveolar mucosae are primarily affected. They are usually asymptomatic and are discovered in routine dental examination. Histologically, the lesions are presented as suprabasal clefts in the epithelium with acantholytic and dyskeratotic cells represented by “corps ronds and grains”. This paper reports a case of a 53-year-old woman that was admitted to our clinic with more than 10-year history of keratotic papules, presented on the hands and feet, nose, ears, genitalia, and whitish lesions on palatal mucosae.

    Full Text Available Intussusception is defined as telescoping of a segment of gastrointestinal tract into an adjacent one. In small children, it is the commonest cause of intestinal obstruction. More than 90% of childhood intussusceptions are idiopathic. We report a rare case of localized small intestinal lymphangiectasia, presenting as intussusception in a 6-month-old male child. The child presented with features of acute intestinal obstruction for which he was later operated. The gross examination of excised ileocecal mass revealed intussusception. Histopathologic examination revealed lymphangiectasia of small intestine, which acted as a lead point for ileocecal intussusception. Postoperative period was uneventful.

    A status report of microinstability as it applies to 2XIIB and MX theory for mirror machines is presented. It is shown that quasilinear computations reproduce many of the parameters observed in the 2XIIB experiment. In regard to large mirror machines, there are presented detailed calculations of the linear theory of the drift cyclotron loss-cone mode, with inhomogeneous geometry and nonlinear diffusive effects. Further, the stability of a mirror machine to the Alfven ion-cyclotron instability is assessed, and the Baldwin-Callen diffusion is estimated for a spatially varying plasma

    In most of the patients Primary EBV infection occurs in childhood as subclinical illness or mild symptomatic disease. In adults EBV infection is almost always a secondary infection due to reactivation of EBV, seen in immunocom-promised patients. In third world countries like Pakistan most of the individuals are exposed to EBV infection in childhood and primary EBV infection in adults is rare. EBV is the primary agent of infectious mononucleosis (IM). We present a patient found to have primary complicated EBV infection in adulthood thus emphasizing that although rare, primary EBV can present in adulthood. Infectious mononucleosis should be suspected in any patient with pharyngitis, posterior cervical lymphadenopathy and splenomegaly.

    Full Text Available Amyloidosis involves all parts of the gastrointestinal tract including the esophagus. The esophageal involvement in amyloidosis has been reported to vary from 13% in a radiology study to 22% in an autopsy series; however, such patients have symptoms of gastroesophageal reflux. Dysphagia is an uncommon presentation of amyloidosis. We report a 64-year-old patient who presented with progressive dysphagia of 4 months duration which was confirmed to be due to primary amyloidosis with multiple myeloma. The esophageal involvement by amyloidosis was confirmed by esophageal mucosal biopsies, and 22-channel high-resolution manometry.

    2013-01-01

    Congenital hypothyroidism is a clinical condition characterized by lack of thyroid hormone because of thyroid gland developmental and thyroid hormone biosynthesis disorders. The most common cause of permanent hypothyroidism is congenital factors. Prompt diagnosis is critical. However, overt signs of hypothyroidism are rarely present at birth, and 95% of affected babies are asymptomatic. Hypoxemia, apnea, acidosis, increased intracranial pressure, vagal stimulus and central nerve system abnormalities represent the most common causes of bradycardia in the neonate. Bradycardia associated with congenital hypothyroidism is very rare. In this paper, a case of severe congenital hypothyroidism, induced by maternal blocker antibodies, who presented with bradycardia, is reported. (author)

    Full Text Available Rasmussen's encephalitis is a rare syndrome characterized by intractable seizures, often associated with epilepsia partialis continua and symptoms of progressive hemispheric dysfunction. Seizures are usually the hallmark of presentation, but antiepileptic drug treatment fails in most patients and is ineffective against epilepsia partialis continua, which often requires surgical intervention. Co-occurrence of focal cortical dysplasia has only rarely been described and may have implications regarding pathophysiology and management. We describe a rare case of dual pathology of Rasmussen's encephalitis presenting as a focal cortical dysplasia (FCD and discuss the literature on this topic.

    2003-01-01

    In the last two decades many laboratories around the world, notably Argonne (ANL), TJNAF (formerly CEBAF), CERN, DESY and KEK, decided to develop the technology of superconducting (SC) accelerating cavities. The aim was either to increase the accelerator energy or to save electrical consumption or both. This technology has been used extensively in the operating machines showing good performances and strong reliability. At present, the technology using bulk niobium (Nb) or Nb coated on copper (Cu) is mature enough to be applied for many different applications, such as synchrotron light sources and spallation neutron drivers. Results, R&D work and future projects will be presented with emphasis on application to linear accelerators.

    2016-01-01

    Full Text Available The odontoameloblastoma (OA, also known as ameloblastic odontoma, is a very rare odontogenic tumor that is similar to ameloblastoma in its locally aggressive behavior. OA includes odontogenic ectomesenchyme in addition to odontogenic epithelium that resembles an ameloblastoma both in structure and in behavior. Its clinical presentation, however, often mimics the more innocuous odontoma, and hence, the recognition of its aggressive nature is commonly only ascertained after its histopathologic diagnosis following enucleation. This paper presents a rare case of OA with unusual clinical and radiological features.

  7. IAEA Safeguards: Present status and experience gained

    Thorne, L.; Buechler, C.; Haegglund, E.

    1983-01-01

    IAEA safeguards are at the present under critical review with regard to their purpose and effectiveness. This paper describes the development of the IAEA Safeguards System from the early days, when procedures were developed on an ad hoc basis, to the present day. The development of State Systems of Accounting for and Control of Nuclear Material (SSAC), and of sophisticated instrumentation, has been necessary to deal with the rapid growth in the quantities of nuclear material and in the number of facilities under safeguards. The paper also discusses some of the managerial and organizational issues that are inherent in such a large international inspectorate. (author)

    The vesical leiomyoma is a tumor of mesenchymal origin, and extremely rare. Most of them are diagnosed casually after the pathologic study of samples collected after surgery. Few cases were found in the reviewed literature, leading us to think of the scarce incidence of this kind of tumors. We present a case treated in our service, of an 18-years-old female patient, assisting to our consultation presenting a polaquiuria, ardor and mictional effort. The complementary exams led to the surgical treatment and follow up of the patient

    A powerful new image presentation technique has evolved over the last twenty years, and its value demonstrated through its support of many and varied common tasks. Conceptually, Rapid Serial Visual Presentation (RSVP) is basically simple, exemplified in the physical world by the rapid riffling of the pages of a book in order to locate a known image. Advances in computation and graphics processing allow RSVP to be applied flexibly and effectively to a huge variety of common tasks such as window shopping, video fast-forward and rewind, TV channel selection and product browsing. At its heart is a

    2011-05-01

    Tumor-induced osteomalacia is a rare acquired condition characterized by phosphaturia, hypophosphatemia and osteomalacia. We report an unusual presentation in a 15-year-old healthy male with a two-week history of cough and chest pain. The chest radiograph showed right middle lobe opacity and chest CT revealed a mass in the extra pleural space. A biopsy showed chondro-myxoidstroma with osteoid formation. Diagnosis was confirmed with the above findings and hypophosphatemia. The patient's symptoms resolved after complete surgical excision of the mass. Tumor-induced osteomalacia, although a rare disorder, can be a diagnostic challenge, especially in patients presenting with atypical symptoms.

    Otto, A.C.; Dunn, M.; Van der Merwe, B.; Katz, M.

    2004-01-01

    Full text: Introduction: Pulmonary embolism is often misdiagnosed by many clinicians because of confusion with pulmonary infarction. According to present literature, the latter seldomly occurs, thus pleuritic pain and hemoptysis are usually absent. The purpose of our study was to re-evaluate the clinical presentation of pulmonary embolism with specific reference to the presence of pulmonary hypertension and pulmonary infarction. Materials and methods: Ethical committee approval was obtained to study fifteen patients with abnormal lung perfusion and high probability for pulmonary embolism retrospectively. Clinical data will be presented in table format. Appropriate symptoms and signs not mentioned was considered absent. Specific investigations not available was considered not done. Results: Will be displayed in table format. The main findings can be summarized as follows: 1. Dyspnea was present in all the patients; 2. Pleuritic pain and hemoptysis was absent in all the patients; 3. None of the patients had clinical signs of pulmonary hypertension or infarction; 4. The available special investigations confirmed the above mentioned findings. Conclusion: The absence of pulmonary infarction and pulmonary hypertension with submassive pulmonary embolism (<60% of pulmonary vascular bed occluded) was reconfirmed and should be emphasized more in clinical practice.

    Most common malignant tumour of the kidney is Renal Cell Carcinoma (RCC) and is known for its unpredictable clinical behaviour. Aetiology and risk factors are not completely understood. Extensive workup is being done in the understanding of the disease, especially to diagnose early and to treat promptly. The objective of this study was to determine the clinical presentation and pathological pattern of RCC. Methods: After approval from ethical committee a retrospective review of records was conducted extending from January 2012 to January 2014 to identify clinical characteristics of renal cell carcinomas. The study included all renal cancer patients presented to Sheikh Zayed Hospital Lahore with in this specified period. The data was retrieved regarding, history, physical examination and necessary investigations such as ultrasonography of abdomen and pelvis and CT scan of abdomen and pelvis. Results: There were total of 50 cases. The male to female ratio was 3:2. Mean age of patients were 52.38 (18-93) years old. Most common clinical presentation was gross haematuria(66%).The mean tumour size was 8.34 (3-24) cm. Tumour histology were clear cell (84%), papillary transitional cell carcinoma (12%) and oncosytoma contributed 4%. Conclusion: We observed that large number of the patients with RCC presented with haematuria and most of them were male. Common pathological type was clear cell carcinoma. (author)

  5. Acute Porphyria Presenting as Epilepsia Partialis Continua

    Directory of Open Access Journals (Sweden)

    Thi Phuoc Yen Tran

    2013-06-01

    Full Text Available Purpose: The porphyrias are a defect in the biosynthesis of heme which can be associated with different neurological symptoms during acute attacks such as peripheral neuropathy, mental disturbance and seizures. So far, there have only been a few case reports of status epilepticus, none of which were of epilepsia partialis continua (EPC. We present here two cases of hereditary coproporphyria (HCP manifesting EPC as part of the clinical presentation. Method: The patients' medical charts, EEG and imaging studies were carefully reviewed. Results: Case 1 is a 49-year-old male who first presented a tonic-clonic seizure. Case 2 is a 30-year-old male who came to the emergency room for a convulsive status epilepticus. Both evolved to EPC over the next days. EPC persisted despite several antiepileptic drug trials. Diagnosis of HCP was confirmed by a high level of urine, fecal and serum porphyrins in both cases and by genetic testing in one. Over the last 3 years, the first patient has continued to present non-disabling EPC and has had four tonic-clonic seizures associated with alcohol consumption. The second patient died from brain edema one month and half after admission. Conclusion: Acute porphyrias should be included in the differential diagnosis of new onset status epilepticus, including EPC. Their recognition is important as it modifies significantly patient management, since many anticonvulsants are porphyrogenic.

    2016-06-01

    A young girl, age 8.5 years, presented with profound hypercholesterolemia and early xanthomatosis, suggesting homozygous familial (or type II) hypercholesterolemia. The patient's low density lipoprotein (LDL) receptor function and parental lipoprotein profiles were determined to be normal, prompting revision of the initial diagnosis to pseudohomozygous familial hypercholesterolemia. When she subsequently presented with giant platelets, the case was presented to colleagues on an electronic mailing list. It was recommended that plasma and sterol analysis be performed, which led to a diagnosis of sitosterolemia. The presentation of profound hypercholesterolomia in childhood that ultimately is not attributed as due to homozygous or compound heterozygous defects in the LDL receptor gene has been termed pseudohomozygous familial (or type II) hypercholesterolemia (PHT2HC). Patients diagnosed with PHT2HC subsequently confirmed to have sitosterolemia have been previously reported only rarely. The challenge of achieving accurate specific diagnosis and appropriate workup for these conditions in children is discussed in the context of this rare case and review of the historical literature concerning these conditions. © 2016 Marshfield Clinic.

    Full Text Available Spontaneous pneumomediastinum is an unusual and benign condition in which air is present in mediastinum. A 20-year-old male patient presented to ED with complaint of hoarseness and odynophagia from the day before, after weightlifting. The patient was nonsmoker and denied history of other diseases. On physical examination he had no dyspnea with normal vital signs. Throat examination and pulmonary auscultation were normal and no crepitation was palpable. We could not find subcutaneous emphysema in neck and chest examination. In neck and chest X-ray we found that air is present around the trachea. There was no apparent pneumothorax in CXR. In cervical and chest CT free air was present around trachea and in mediastinum. Subcutaneous emphysema was also evident. But there was no pneumothorax. The patient was admitted and went under close observation, oxygen therapy, and analgesic. The pneumomediastinum and subcutaneous emphysema gradually resolved within a week by conservative therapy and he was discharged without any complication. Many different conditions could be trigged because of pneumomediastinum but it is rarely seen in intense physical exertion such as weightlifting and bodybuilding. Two most common symptoms are retrosternal chest pain and dyspnea. But the patient here complained of hoarseness and odynophagia.
