Se realizó una investigación cualitativa, clasificándose el estudio como una investigación documental, no experimental. El diseño de investigación fue documental explicativo.Las unidades de análisis para el desarrollo de los tópicos investigados fueron las leyes y normas que rigen la materia de salud y seguridad laboral en nuestro país:LOPCYMAT (2005; Reglamento de la LOPCYMAT (2007; la norma técnicas de INPSASEL NT- 02-2008; las Sentencias del Tribunal Supremo de Justicia (2008, 2005, 2004, 2003, 2000; la Ley Orgánica del Trabajo (1997; el Código Civil (1982 y el Código Penal (2005 y los diferentes estudios e investigaciones desarrollados por instituciones e investigadores de prestigio internacional y nacional en materia de riesgos psicosociales. Se concluye, en primer lugar, que la responsabilidad legal de prevención de los riesgos psicosociales, recae sobre los mandos superiores: Gerentes, Ejecutivos, que actúan a nombre y por la empresa y finalmente se hace necesaria una adecuada comprensión de los riesgos psicosociales y sus factores para una prevención efectiva.

    Full Text Available El uso de computadores como apoyo pedagógico orientado a incentivar el interés y el desarrollo de nuevas formas de pensar y de solucionar problemas puede ser un instrumento útil en la enseñanza del código lector. Estudios realizados con preescolares y escolares han demostrado un mejor rendimiento escolar y un efecto positivo en habilidades de lectura, matemáticas, y en general cognitivas, en niños que utilizan un computador con software educativo quince a veinte minutos por día. El objetivo del presente estudio fue evaluar la progresión de las habilidades verbales, integración viso-motora y de lectura en niños que usaron computadores y compararlos con un grupo que continuó con la educación tradicional. Todos los niños fueron estudiados antes de iniciar la intervención pedagógica. La evaluación inicial mostró una puntuación inferior para la edad en todas las pruebas aplicadas. El 11% de la población estudiada se catalogó como en alto riesgo de tener problemas en el aprendizaje. En la segunda evaluación se encontró un cambio positivo respecto a la puntuación inicial. Sin embargo, a excepción de algunos ítems, no se encontraron diferencias signifi cativas al comparar los grupos de uso o no de computadores. En conclusión, las políticas acerca del uso de computadores deben ser revaluadas, pues los niños de nuestras escuelas públicas provienen de ambientes privados de oportunidades para el uso de tecnología

Consideramos que para este propósito es necesario sustentar una concepción particular de la flexibilización curricular en la universidad, como principio fundamental del “desempeño profesoral”, que nos permita reflexionar sobre la esencia de la universidad y sus fundamentos, como una de las tantas sustentaciones que necesitamos para salir de la muy citada “crisis universitaria”. AbstractThis document pretends to contribute some elements for the debate within the academic unities of the universities that accomplished their processes of quality and high quality certification, but which still present some difficulties in the process of “teachers´ performance”. We consider that for this specific purpose, it is necessary to maintain a particular conception of the curricular flexibility in the university, as a fundamental principle of the “teachers´ performance”, which lets us think about the essence of the university and its foundations, as one of the different elements that we need to overcome the so-called u “universitarian crisis”.

    Full Text Available A comienzos del siglo XX, la reestructuración política republicana en Colombia implicó la preeminencia de las obras civiles gubernamentales sobre las religiosas (herederas del régimen colonial. Sin embargo, la obra arquitectónica de mayores dimensiones en Ibagué fue la Iglesia del Carmen. Esta disyuntiva condujo a la indagación de fuentes notariales, colecciones fotográficas y cartográficas, de las cuales se obtuvieron datos que luego fueron comparados para comprender la relación entre la arquitectura y las dinámicas sociales subyacentes. Así, se descubrió la estructura política, educativa y religiosa que intervino en la materialización arquitectónica de las ideas de la época, consistente en que el gobierno delegó en las órdenes religiosas las labores educativas necesarias para el desarrollo nacional, amalgamando así las tendencias políticas y educativas con las religiosas, para generar una estrategia que publicitó la arquitectura como símbolo del desarrollo económico.

    Full Text Available A doença de Lyme é afecção sistêmica causada pela espiroqueta Borrelia burgdorferi, transmitida pelo carrapato. É descrita principalmente nos países do hemisfério norte, sendo pouco relatada no Brasil. O objetivo deste trabalho é documentar uma paciente com doença de Lyme que apresentou pupila tônica bilateral como única seqüela oftálmica da afecção. Trata-se de uma menina de 13 anos de idade, com diagnóstico de doença de Lyme, que apresentou paralisias facial periférica e do oculomotor bilaterais. Após recuperação do quadro neurológico manteve anisocoria, fraco reflexo fotomotor, amplitude de acomodação inferior ao normal, constrição pupilar tônica para perto e redilatação lenta em ambos os olhos. O teste com pilocarpina a 0,1% foi positivo em ambos os olhos, confirmando a suspeita clínica de pupila tônica bilateral. Este é o primeiro caso relatado de pupila tônica bilateral causado pela doença de Lyme.Lyme disease is a multisystemic disorder caused by Borrelia burgdorferi spirochete, transmitted by ticks. Mainly described in the northern hemisphere and rarely in Brazil. The purpose of this report is to describe a patient with Lyme disease who developed bilateral tonic pupil as the only remaining sign.

    Full Text Available Identificar y analizar las publicaciones que traten sobre las repercusiones o consecuencias de una muerte materna en la familia. Método: revisión sistemática de publicaciones de investigaciones cualitativas y cuantitativas en revistas indexadas de bases de datos biomédicas en los idiomas inglés, portugués y español. Resultados: de las siete publicaciones incluidas tres usan metodología cualitativa, dos cuantitativa y dos cualicuantitativa, con procedencias de los continentes europeo y americano. En el total de los artículos revisados participaron 439 familias de mujeres fallecidas y se realizaron dos reconstrucciones históricas a partir de los registros familia- res de dos poblaciones. Las consecuencias de una muerte materna son de tal dimensión que repercuten durante mucho tiempo, tanto en la familia como en la comunidad misma. Al analizar los hallazgos encontramos problemas en común como son: el duelo, la supervivencia de los hijos, la reconstitución de los hogares. Conclusiones: aunque son escasos los trabajos que identifican y cuantifican las consecuencias familiares de una muerte materna y su análisis se restringe a algunos estudios cualitativos, estas producen un impacto negativo en la estructura y dinámica familiar, así como el aumento en la morbi-mortalidad infantil.

Las consecuencias a largo plazo para estos niños varían desde efectos nocivos en su desarrollo hasta trastornos psicológicos, psiquiátricos y orgánicos. Es importante resaltar que aún con muy buenas intervenciones no todas tienen el éxito esperado si no se hacen de manera correcta. Esindispensable contar con estrategias de prevención que incluyan personal bien entrenado, una supervisión adecuada, los recursos necesarios, y un tiempo mínimo óptimo para enfrentar el problema y obtener los mejores resultados. ______________________________________________________________________Domestic violence is one of the most common forms of violence found both domestically and internationally. Within these, child abuse has alarming figures. This is the subject of this review. The effects of this problem significantly impact on those who survive; their long-term consequences are most severe and expensive for victimized child and his/her family than associated primary physical injuries. Thelong-term consequences for these children range from adverse effects on its psycholigical development to psychological, psychiatric organic disoders. It is important to note that good speeches are not enough to achieve success if any intervention are not done correctly. All prevention strategies include well-trained staff, appropriate supervision, resources, and a optimal time for addressing this problem to get the best results.

El Doctor Láscaris fue un prolífico ensayista y escritor de varios libros sobre filosofía y pensamiento en Costa Rica y Centroamérica. El ensayo Consecuencias de la noción de existencia es una refrescante reflexión de un tema que es tan vigente hoy como hace 30 años sobre las bases filosóficas, desde la óptica del existencialismo, de cuestiones controversiales sobre el momento en que el ser humano puede considerarse titular de todos los derechos de una persona o sobre los fundamentos éticos del control de la natalidad. Uno de los méritos del ensayo es que trasciende el dogma religioso que tan difícil hace las discusiones de estos temas.

    2010-12-01

    Full Text Available O trabalho analisa a mudança na estratégia de inserção regional e internacional do Chile no começo dos anos 1990, com ênfase em acordos comerciais bilaterais, depois de ter praticado a abertura comercial generalizada desde meados da década de 1970. A opção por acordos bilaterais foi adotada pelo primeiro governo democrático, como parte da orientação de manter e aprofundar a abertura externa empreendida pela ditadura, e conseguiu ampliar as vendas externas e diversificar produtos e destinos. As exportações têm papel decisivo na economia chilena, aberta e pequena, e os 24 acordos bilaterais de comércio com diferentes países e regiões, além de outros em negociação, podem ser explicados pelo esgotamento das possibilidades de ampliar o comércio por meio de reduções adicionais da tarifa externa unilateral, hoje em 6% para quase todos os produtos. A formação de uma rede de acordos bilaterais ampla e diversificada, contudo, tem também interesses políticos, estratégicos e de segurança em relação a vizinhos e a países próximos, além de evitar que o Chile precise se integrar, como membro pleno, a blocos regionais para garantir seus interesses, o que amplia as possibilidades de lidar com diferentes e importantes parceiros no âmbito internacional.The paper analysis the change of Chile's regional and international strategy of insertion through bilateral trade agreements in the beginning of the 90s, after a generalized trade opening since the middle of the 70s. The bilateral trade agreements strategy was set up by the democratic governments as part of the direction of maintaining and deepening the unilateral trade liberalization undertaken by the dictatorship, enlarging exports and diversifying products and markets. Exports have a decisive role in Chile's economy, open and small.

    Full Text Available On 24 February 1895 most people in Cuba did not want a war of independence, because reforms for the island had been approved by the Madrid parliament. The reaction to the insurrection begun in Cuba on that date by the Spanish government of Antonio Cánovas del Castillo was to treat all Cubans as rebels. In 1896 Cánovas sent general Weyler to Cuba, and by the end of 1897 he had stopped the advances of the insurrectionists, but the forced removal of the rural population into urban settlements that he decreed in order to prevent their assistance to the insurgents, led to thousands of deaths by hunger and disease, and in the United States public opinion began to clamor for intervention in Cuba to expel Spain, and this was advised by people like the Consul General in Havana, Fitzhugh Lee. The war begun in 1895 for the independence of Cuba had as consecuences the war of the United States with Spain in 1898 and its transformation into a world power with the colonies that it took from Spain in Asia and America.El 24 de febrero de 1895 la mayor parte de los habitantes de Cuba no deseaba una guerra de independencia, porque se acababa de votar en el parlamento de Madrid por reformas liberalizantes para la isla. La reacción del gobierno de Antonio Cánovas del Castillo a la insurrección iniciada en Cuba en esa fecha fue no implementar las reformas y tratar a todos los cubanos como insurrectos. En 1896 Cánovas envió al general Weyler a Cuba, quien logró frenar el avance de los insurrectos, pero la reconcentración de los campesinos en centros urbanos que este decretó para privar de su apoyo a los insurrectos causó miles de muertes por hambre y enfermedad y en los Estados Unidos la opinión pública comenzó a favorecer la intervención en Cuba, acción aconsejada por expansionistas como el Cónsul General de los Estados Unidos en La Habana, Fitzhugh Lee.

    Full Text Available Relato de caso com acometimento bilateral do seio cavernoso causado por linfoma não-Hodgkin em um paciente com síndrome da imunodeficiência adquirida. Paciente de 51 anos infectado pelo vírus da imunodeficiência adquirida há dois anos, sem terapia antirretroviral, apresentou-se com acometimento dos V e VI nervos cranianos bilateralmente. Exame de tomografia computadorizada de órbitas mostrou-se dentro da normalidade. Como a hipótese diagnóstica principal era afecção do ápice orbitário ou do seio cavernoso, foi realizado exame de imagem por ressonância magnética que evidenciou lesão compatível com linfoma acometendo os seios cavernosos. Apesar da raridade dos linfomas primários do sistema nervoso central, essa condição deve ser considerada entre os diagnósticos diferenciais nos pacientes imunodeprimidos que apresentem oftalmoplegia e sinais radiológicos sugestivos de lesão infiltrativa do seio cavernoso.

RELATO DO CASO: Paciente do sexo feminino, 61 anos, estado físico ASA I, submetida à anestesia geral associada a bloqueio paravertebral cervical para reparo artroscópico de lesão de manguito rotator. Após extubação foi evidenciado bloqueio neuromuscular residual por meio do exame clínico. Na sala de recuperação pós-anestésica evoluiu com sonolência, taquicardia, hipertensão arterial e acidose respiratória grave. Após a reintubação, evoluiu com parada cardíaca em atividade elétrica sem pulso, revertida com adrenalina e massagem cardíaca externa. Apresentou no pós-operatório elevação de segmento ST, aumento de troponina e acinesia de segmento médio-apical de ventrículo esquerdo com fração de ejeção estimada em 30%.

El objetivo de este trabajo fue evaluar el cambio de las comunidades de lombrices de tierra y de algunas propiedades físicas, químicas y fisicoquímicas en suelos con SD en relación a pastizales naturales (PN, en la cuenca Gral. Deheza, Córdoba. Las lombrices de tierra se obtuvieron según el método del programa TSBF. Se observó un aumento de la compactación y una disminución en el contenido de materia orgánica (MO y del pH en los sitios con SD con respecto a los PN. La comunidad de Lumbricina estuvo dominada por lombrices endogeas, claves en los procesos edáficos al modificar tanto aspectos químicos como físicos del suelo. En SD disminuyó la población de Lumbricina de una media de 297 ind m-2 a 70 ind m-2 con respecto a los PN y aumentó la proporción de individuos en diapausa y juveniles. Esto se explica principalmente por la mayor compactación y el menor contenido de MO. El aumento de organismos juveniles y en diapausa también podría estar asociado a la influencia negativa del intenso uso de agrotóxicos. Se concluye que en la región estudiada, los suelos bajo SD estarían comprometidos en el cumplimiento de las «funciones ecosistémicas» que son la base de su calidad.

    Full Text Available En el procedimiento de consecuencias diferenciales (PCD a un organismo se le presenta un estímulo (E1 en cuya presencia se requiere una respuesta (R1, que produce un reforzador específico (r1, y en presencia de un segundo estímulo (E2, se requiere una segunda respuesta (R2, que produce un reforzador distinto (r2, lo que resulta en un incremento en la velocidad de adquisición y precisión final en tareas de discriminación condicional. Una explicación basada en una teoría de dos factores establece que el uso de consecuencias diferenciales involucra la activación de expectativas del reforzador a través de un mecanismo pavloviano, las cuales promueven la activación de un sistema de memoria implícita en la solución de tareas de discriminación condicional. De acuerdo con esto, la expectativa del reforzador es una señal que guía la respuesta del organismo. Recientemente se ha demostrado el efecto del PCD en situaciones donde lo que se aprende no se observa directamente, como sucede en la manipulación de un intervalo de retención en la interferencia retroactiva.

    Full Text Available Introducción: El abuso sexual en menores de edad es uno de los tipos de maltrato infantil con peores repercusiones en sus víctimas y que usualmente coexiste con otros tipos de violencia. Incluye tanto agravios que no involucran contacto físico como aquellos que sí lo hacen, lo que cubre una amplia gama de posibilidades. Objetivo: Debido a lo trascendental de esta problemática, se realizó está revisión bibliográfica con el fin de exponer la importancia del tema de abuso sexual en menores de edad, sus aspectos generales, consecuencias y medida preventivas. Síntesis de datos: El abuso sexual es frecuente. Las víctimas suelen ser mujeres a pesar de que existen ciertos factores de riesgo que predisponen a ciertos niños a ser agredidos, y sus abusadores por lo general son personas cercanas a ellos. Las consecuencias tanto a corto como largo plazo abarcan todos los aspectos del ser humano y la magnitud de su gravedad dependerá de diversos factores. Existen métodos de prevención primaria y secundaria, que van desde programas educativos y campañas publicitarias hasta medidas judiciales. Conclusiones: Es necesaria más información relativa al abuso sexual en menores y es imprescindible liberarse de los estereotipos en torno a esta problemática para detectar a tiempo posibles casos de abuso. Toda víctima deberá obtener una atención individualizada posterior al suceso, dirigida a atenuar las secuelas. El abordaje del abuso sexual se deberá hacer desde diversas perspectivas y todos estamos a cargo de su combate.

    Full Text Available En las últimas décadas el abuso sexual infantil (ASI ha suscitado un gran interés, tanto entre la comunidad científica, como en la sociedad en general, debido a su prevalencia y consecuencias a corto y a largo plazo. Aunque la mayoría de los estudios que han examinado las secuelas del ASI enumeran numerosas dificultades psicológicas, sociales, conductuales y físicas, ciertamente no todas las víctimas de abuso infantil muestran un daño significativo posterior, existiendo una amplia variabilidad en el ajuste de las víctimas. Ante esta diversidad el presente trabajo, tras realizar una revisión de las consecuencias a corto y largo plazo del ASI, pretende discernir cuales son las principales variables que determinan los efectos del abuso sobre la víctimas. Las características del abuso, víctima y agresor, los factores situacionales y, especialmente, las variables cognitivas de la víctima se han demostrado como eficaces para explicar la gravedad de la sintomatología. Concretamente, las investigaciones realizadas en los últimos años han encontrado que la sustitución de estrategias de afrontamiento de evitación por estrategias de aproximación, la eliminación de las atribuciones de autoinculpación e inculpación a la familia y de los sentimientos relacionados con las cuatro dinámicas traumatogénicas y la promoción de un estilo de apego seguro resultarían beneficiosos a la hora de prevenir futuros problemas causados por la experiencia de abuso.

    Full Text Available De acuerdo con los modelos teóricos que llaman la atención sobre la consideración del burnout como un proceso transaccional entre la persona y el medio laboral (Cherniss, 1980; Moreno-Jiménez, González-Gutiérrez y Garrosa, 2001, el presente trabajo examina las dimensiones de desgaste profesional que, junto con los factores antecedentes organizacionales y profesionales del síndrome específicas de la profesión de Terapia Ocupacional, se encuentran asociadas a los diferentes niveles de consecuencias planteadas en la literatura sobre el síndrome. Para ello se empleó una muestra de 110 terapeutas ocupacionales que desempeñan su actividad clínica en la Comunidad Autónoma de Madrid. A través del desarrollo de un análisis de regresión jerárquica se ha observado la existencia de asociaciones altamente significativas entre el síndrome y la presencia de consecuencias adversas para la salud del individuo, así como para su área interpersonal y para la propia organización en la que desarrolla su actividad laboral, siendo el agotamiento emocional la dimensión más asociada a las mismas. Junto a ello, se ha identificado la relevancia explicativa de los problemas extralaborales que afectan al área laboral, así como de otros factores que podrían actuar a través de la generación de desgaste, como son la sobrecarga de trabajo, las características de la tarea, la falta de apoyo y reconocimiento por parte del equipo, y el miedo a la malpráctica.

Es un hecho que acompaña al envejecimiento aunque no siempre tiene consecuencias clínicas.Se produce por multitud de factores: sistema nervioso (pérdida de unidades motoras alfa de la médula espinal, musculares (pérdida de la calidad y masa muscular, humorales (descenso de hormonas anabolizantes como testosterona, estrógenos y GH y aumento de distintas interleukinas y de estilo de vida (actividad física.Las principales consecuencias clínicas de la sarcopenia tienen relación con la independencia funcional. Así los ancianos sarcopénicos tienen más dificultad para caminar o lo hacen más lentamente, para subir escaleras, para realizar las actividades básicas de la vida diaria. Estas dificultades aumentan el riesgo de caídas y por lo tanto de fracturas. También afecta a la formación de hueso, a la tolerancia a la glucosa y a la regulación de la temperatura corporal. Además la dependencia es un factor de riesgo de mortalidad.The concept of sarcopenia implies loss of muscle mass and function. It is a condition that accompanies aging, although it not always has clinical consequences. It is produced by many factors: nervous system (loss of alpha motor units in the spinal cord, muscular (loss of muscle quality and mass, humoral (decrease in anabolic hormones such as testosterone, estrogens, GH, and increase of several interleukines, and life style (physical activity. The main clinical consequences of sarcopenia relate with functional independence. Thus, the sarcopenic elderly has greater difficulty walking, or do it more slowly, climbing up stairs, or doing basic daily living activities. These difficulties increase the risk for falls and, thus, fractures. They also affect bone formation, glucose tolerance, and body temperature regulation. Besides, dependency is a mortality risk factor.

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

Though this development increases the probability not to have daughters, there are no clear signs of a weakening of intergenerational ties derived from the development of a beanpole type kin structure. The biggest threat for the density of intergenerational relationships derives not as much from this development, but from the geographical dispersion of the generations caused by the lack of professional and employment opportunities for the younger generations.

    El objeto de este trabajo es analizar los efectos de la caída de la fecundidad sobre los intercambios materiales e inmateriales entre las generaciones (adultas y residentes en hogares independientes en España. El análisis atiende, entre otras variables, al número y a la composición por sexos de la generación más joven, analizando los intercambios entre las díadas hijo varón emancipado / padres e hija emancipada / padres. Los efectos de la caída de la fecundidad y otros cambios familiares asociados a la misma dependen del punto de vista que se adopte, esto es, si se analizan desde el punto de vista de los padres o de los hijos. A pesar de que la caída de la fecundidad aumenta la probabilidad de no tener hijas, no hay signos claros de un debilitamiento de las relaciones intergeneracionales derivadas de la caída de la fecundidad. Las mayores amenazas para la densidad de las relaciones intergeneracionales no derivan tanto de la caída de la fecundidad, como de la dispersión de las generaciones como consecuencia de la ausencia de expectativas laborales y profesionales para la generación más joven en

    Full Text Available La escleritis posterior es un proceso inflamatorio de la parte posterior de la esclera. Su prevalencia es muy baja y el diagnóstico puede resultar complicado por la ausencia de signos oculares externos. Es más frecuente en mujeres. Cuando aparece en pacientes jóvenes no suele tener otras patologías asociadas, pero en mayores de 55 años hasta un tercio de los casos tienen relación con alguna enfermedad sistémica, sobre todo la artritis reumatoide. El diagnóstico de esta patología puede requerir un abordaje multidisciplinar y la colaboración de oftalmólogos con neurólogos, internistas o reumatólogos. En este artículo se describe un caso de escleritis posterior bilateral idiopática.Posterior scleritis is an inflammatory process of the posterior part of the sclera. Its prevalence is very low and its diagnosis can be complicated due to the absence of external ocular signs. It is more frequent in women.

    Osteomas are the most common benign osteoclastic tumours of the paranasal sinuses. However, nasal cavity and turbinate osteomas are extremely rare. Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma. A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively. To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

Se entiende que el registro arqueológico puede hallarse actualmente en una variedad de ambientes tanto terrestres como subacuáticos a causa de varias razones, como por ejemplo las oscilaciones de los niveles de agua ocurridas entre el Pleistoceno Final y el Holoceno Medio. Por lo tanto, se propone que para su recuperación debe utilizarse una metodología adaptada al medio ambiente en el cual se encuentre. En este sentido, es importante la interpretación integral del paisaje para acceder a la comprensión de la diversidad ambiental en la que se puede emplazar un sitio arqueológico, y en consecuencia poder “bucear” un registro integrado.

    Los objetivos del articulo son 1 analizar las consecuencias de la flexibilidad laboral en el curso vital de los individuos, 2 asi como saber si la flexibilidad ha socavado o reforzado la importancia de las clases sociales, de la educacion y del genero en distintos aspectos concernientes al curso vital, sobre todo relacionados con el empleo en Espana. La peculiaridad espanola con respecto a la flexibilidad radica en la alta proporcion de contratos temporales. La mayor diferencia entre estos contratos y los indefinidos es su menor coste de despido. La manera en la que el Estado del Bienestar ha introducido la flexibilidad ha logrado un equilibrio de riesgos entre generaciones, por lo que no puede decirse que haya unos claros ganadores o perdedores. Los datos indican que los efectos de la flexibilizacion sobre el curso vital de los individuos son mucho mas modestos de lo que las hipotesis preven. Asimismo, la flexibilización no ha mermado la importancia de las clases sociales ni de los niveles de estudio para explicar la posición de los individuos en el mercado laboral, aunque tampoco hay una clara evidencia de que las brechas entre los individuos de distintas clases ocupaciones o con distintos niveles de estudio hayan aumentado en Espana.

    The objectives of the paper are 1 to analyse the effects of labour flexibility on individuals from a lifecourse perspective and 2 to know whether flexibility has undermined or reinforced the effects of social classes, education and gender on several aspects concerning the life-course, above all those related to employment in Spain. The peculiarity of the Spanish case lies in the proportion of fixed-term contracts. The greatest difference between these contracts and permanent contracts is not the job to be done, or even its temporary or permanent nature, but rather the lower layoff cost. The way that the Welfare State has introduced flexibilisation has achieved a balance of risks between the generations

    2015-11-01

    This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF). The constant-time means that the computational complexity is independent of its filter window size. Although many existing constant-time bilateral filters have been proposed step-by-step to pursue a more efficient performance tradeoff, they have less focused on the optimal tradeoff for their own frameworks. It is important to discuss this question, because it can reveal whether or not a constant-time algorithm still has plenty room for improvements of performance tradeoff. This paper tackles the question from a viewpoint of compressibility and highlights the fact that state-of-the-art algorithms have not yet touched the optimal tradeoff. The CBLF achieves a near-optimal performance tradeoff by two key ideas: 1) an approximate Gaussian range kernel through Fourier analysis and 2) a period length optimization. Experiments demonstrate that the CBLF significantly outperforms state-of-the-art algorithms in terms of approximate accuracy, computational complexity, and usability. PMID:26068315

La paradoja del momento actual en Norteamérica consiste en los esfuerzos por eliminar las fronteras que restringen la libre circulación de mercancías y de capital, por una parte, y, por otra, el afán de limitar el libre paso a la fuerza de trabajo. La intensificación de los métodos de control y vigilancia estadounidenses en la frontera con México, y de México con Centroamérica, representa un considerable incremento en los riesgos y costos de la migración, al mismo tiempo que significa el triunfo y el fracaso de la política migratoria de ambos países en cuanto a detener los flujos de trabajadores indocumentados.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    Freddo, T F; Leibowitz, H M

    1985-04-01

    A 38-year-old man with brittle, juvenile onset diabetes mellitus and bilateral severe dry eyes with recurrent corneal ulcers developed atypical band-shaped calcifications of both corneas during a 24-hour period. Serum calcium, phosphate, and carbon dioxide levels all were within normal limits. The patient was mildly uremic but was not in renal failure. When EDTA chelation failed to clear the deposits, partial keratectomies were performed in both eyes and the specimens were examined by light and electron microscopy, including energy dispersive x-ray analysis. Microscopic studies revealed an atypical calcific keratopathy which involved neither Bowman's layer nor the most superficial stromal lamellae. The deposits were confined to deeper lamellae in the anterior stroma and by electron microscopy were composed of extracellular crystalline aggregates. Energy dispersive x-ray analysis of these aggregates confirmed the presence of calcium and phosphate. Corneal dessication appeared to be a major contributing factor in the rapid formation of these deposits.

    STALE EINARSEN

    2006-01-01

    Full Text Available El presente artículo revisa y resume la investigación y la literatura sobre el concepto de acoso psicológico en el trabajo, su naturaleza, consecuencias, y antecedentes. El acoso psicológico en el trabajo hace referencia a conductas negativas continuadas que son dirigidas contra uno o varios empleados por sus superiores y/o colegas. Alrededor del 1-10% de los trabajadores están expuestos a comportamientos de acoso. El acoso puede conducir a problemas emocionales y psicosomáticos, a un menor bienestar en las víctimas, y a un incremento en el absentismo y la rotación en las organizaciones. Se han propuesto como posibles antecedentes del acoso psicológico en el trabajo desde las características de personalidad hasta los factores organizacionales. Se ha encontrado que los individuos introvertidos, neuróticos y sumisos tienen mayor probabilidad de ser acosados. Se han investigado una amplia variedad de posibles estresores del entorno laboral en relación con el acoso psicológico, siendo las deficiencias en el liderazgo y el diseño del trabajo los factores que propician el acoso. Del mismo modo, existe una atención creciente hacia los cambios en la naturaleza del trabajo, donde los cambios organizacionales y el incremento de la incertidumbre han sido estudiados en relación con el acoso. Aunque se necesita mayor investigación en esta área, existe suficiente evidencia para afirmar que la mayoría de las organizaciones deberían esforzarse en la prevención y el manejo de este problema.

    DEFF Research Database (Denmark)

    Mørkenborg, Marie-Louise; Frendø, M; Stavngaard, T;

    2015-01-01

    BACKGROUND: Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating...... from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning...... embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. CONCLUSION: This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral...

    2007-01-01

    Full Text Available A partir de los años 60 se observó, coincidiendo con el desarrollo de técnicas de contracepción eficaces y con la incorporación femenina al mundo laboral, que en algunos países europeos con mayor nivel de bienestar, la edad a la que ocurría la primera maternidad se iba retrasando progresivamente. Es sabido que conforme la edad de la mujer aumenta, además de posibles efectos negativos sobre el recién nacido (bajo peso y prematuridad, su fecundidad disminuye debido, tanto a cambios en la frecuencia de relaciones sexuales, como a una menor fecundabilidad y a una mayor probabilidad de aborto. En ocasiones, se intenta resolver la dificultad de concebir mediante el recurso de técnicas de reproducción asistida. Cabe preguntarse si estas técnicas implican algún riesgo en cuanto a la mortalidad o morbilidad del niño. Diversos estudios han puesto en evidencia que aquellos concebidos por reproducción asistida, acumulan más del doble de defectos congénitos que los fecundados de forma natural. Otra consecuencia negativa es la aparición de gestaciones múltiples, las cuales se asocian con un menor peso al nacimiento y mayor incidencia de prematuros. Además, ya sea por una mayor probabilidad de anomalías congénitas o por otras causas (tales como el síndrome transfusional, las gestaciones múltiples resultan en una mayor frecuencia de pérdidas fetales tardías. Por lo que se refiere a la mortalidad perinatal, la mayoría de los estudios indican un riesgo superior relacionado con los tratamientos de reproducción asistida, debido principalmente, pero no exclusivamente, a la mayor incidencia de múltiples. De todo lo anterior, se concluye la necesidad de planificar el coste sanitario que puede suponer la atención de recién nacidos prematuros y de bajo peso, resultado de una edad de maternidad elevada asociada a tratamientos de reproducción asistida.

    Antecedentes: el linfoma de Burkitt es una forma agresiva de los linfomas no Hodgkin de células B que ocurre con mayor frecuencia en niños y adultos jóvenes; el linfoma de ovario puede aparecer como lesión primaria o, más comúnmente, como una metástasis. Las lesiones primarias de ovario son manifestaciones raras que corresponden a 0.5% de los linfomas no Hodgkin y 1.5% de los tumores de ovario. Caso clínico: paciente femenina de 31 años de edad, con debilidad generalizada, incapacidad para la marcha, disnea, hiporexia, fiebre, diaforesis, pérdida de 20 kg de peso, abdomen plano, con dolor abdominal; Ca125 610 U/mL. La tomografía computada abdominal mostró un gran tumor de aspecto sólido que afectaba a la cavidad pélvica derecha. Se extirparon los tumores ováricos bilaterales. Desde el punto de vista microscópico ambas lesiones muestran una imagen en "cielo estrellado" compuesta por un patrón de infiltrado monótono de linfocitos mezclada con macrófagos de citoplasma amplio y claro, abundantes mitosis atípicas, zonas de necrosis y hemorragia. La inmunohistoquímica reveló positividad para CDI0 y CD20, negativo con CD3, índice de proliferación Ki67 alto. Se diagnosticó linfoma tipo Burkitt bilateral de ovario. Conclusiones: el linfoma de Burkitt de ovario bilateral es poco frecuente, con variabilidad de presentación; el dolor abdominal y los tumores abdominales son lo más frecuente. El pronóstico a corto plazo de las pacientes es malo, por lo que es necesario conocer esta afección para poder establecer el diagnóstico temprano.

  2. Barrios cerrados como estrategia de desarrollo municipal

    2010-07-01

    Full Text Available Los barrios cerrados han sido generalmente estudiados desde la perspectiva de sus residentes, preferencias, estatus económico, y ambiciones sociales. Aun más, estos proyectos han sido asociados con el debilitamiento del estado y un desarrollo urbano gobernado por las necesidades del mercado. Sin embargo, queda por responder cual ha sido el papel de las instituciones públicas en la proliferación de barrios cerrados. Este artículo analiza el caso de Buenos Aires, donde las municipalidades suburbanas más pobres han visto a las urbanizaciones cerradas como una estrategia de desarrollo local. Aprovechando la descentralización de la reglamentación sobre los usos del suelo del nivel provincial al municipal, las municipalidades con un alto porcentaje de hogares pobres han facilitado el desarrollo de urbanizaciones cerradas como estrategia para aumentar el empleo local y la inversión privada en la zona. Como consecuencia de esta política, las urbanizaciones cerradas se han concentrado en las municipalidades más pobres del cono urbano bonaerense. Así, se ha incrementando la polarización social dentro de cada municipalidad, lo cual llama a revisar el efecto de las reformas de descentralización en la formación de una sociedad mas inclusiva y participativa.

    This paper is a short introduction to how the sinusoidal voltage waves are generated. A revision is made on the way of representing a distorted wave and the way of quantifying its harmonics content (harmonics distortion). An overview is made of the non-lineal consuming elements that produce distortion of the current waves. A revision is made on the concept of a power factor in conditions of waves with harmonic distortion. The consequences of feeding with distorted waves the different devices such as motors (particularly for the distortion originated by the rectifiers and the velocity electronic controls), transformers and capacitors. Mention is made of some of the methods for not to produce or for reducing the harmonic effect in the electric networks. The purpose of this article is to review the consequences on energy consumption by the presence of harmonics.

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    2011-06-01

    Full Text Available Objetivos: Los resultados de diversos estudios sugieren la existencia de un período crítico en el desarrollo del individuo en el cual la experiencia de maltrato y abuso sexual puede conllevar cambios neurobiológicos permanentes o muy duraderos, afectando especialmente a la respuesta del eje neuroendocrino hipotálamico-hipofisario-adrenal. El objetivo de este trabajo es ofrecer una revisión actualizada de las principales consecuencias neurobiológicas del abuso sexual infantil. Métodos: Se seleccionaron aquellas publicaciones de enero de 1999 a enero de 2010, en inglés o español, centradas en las consecuencias neurobiológicas relacionadas con la experiencia de abuso sexual infantil mediante las bases de datos Medline, Scopus, Psycinfo y Web of Science. También se examinaron las listas de referencias de estudios publicados acerca de las consecuencias neurobiológicas de la victimización en la infancia. Resultados: Se incluyeron 34 estudios sobre consecuencias neurobiológicas del abuso sexual infantil, de los cuales se extraen alteraciones neuroendocrinas, estructurales, funcionales y neuropsicológicas que afectan a un importante número de víctimas. Conclusiones: Los trabajos que hasta ahora han explorado los efectos neurobiológicos del maltrato muestran que es necesario considerar a éste y al abuso sexual infantil como problemas de salud que afectan a diferentes áreas de la vida de sus víctimas, favoreciendo así el desarrollo de programas de intervención y tratamiento teniendo en cuenta sus múltiples efectos.Objective: The results of several studies suggest that there is a critical timeframe during development in which experiences of maltreatment and sexual abuse may lead to permanent or long-lasting neurobiological changes that particularly affect the hypothalamus-pituitary-adrenal axis response.

Se puede afirmar que ésta actualmente se rige por los Objetivos del Milenio y los establecidos en el «Programa de Educación para Todos», incorporando poco a poco el concepto del Desarrollo Humano Sostenible, dando cabida a la diversidad cultural como un aspecto sustancial de la sostenibilidad. Estos planteamientos teóricos tienen consecuencias directas en los programas y proyectos de cooperación educativa. A grandes rasgos, destacan iniciativas de educación intercultural y propuestas que priorizan la revalorización de las culturas, gozando de características comunes pero también de relevantes rasgos diferenciadores. Establecer estos encuentros y desencuentros será el objeto de este trabajo, con el propósito de aportar diversas perspectivas para la cooperación educativa internacional ante el reto actual de la sostenibilidad cultural y ambiental.Diverse reflections have been taken place around the concepts of culture and development during the present century, which have revealed deep influence on the International Cooperation in Education. Nowadays there is no doubt that this issue is governed by the so called Millenium Aids, and by those objectives such as the ones established in the «Programof Education for All». These two frames have gradually incorporated the concept of Sustainable Human Development, allowing the cultural diversity become a substantial aspect of sustainability.These theoretical reflections have direct consequences on the programs and projects involved in the Cooperation in Education. Broadly speaking, it can be stated that intercultural educational initiatives and proposals, while they have the revaluation of cultures as main priority, they both share common characteristics and reveal relevant differences.

    2014-01-01

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

A 28-year-old woman presented with one-year history of progressive headache, nausea, vomiting, and blurred vision. Neurologic examination revealed a bilateral mild papilledema, mild dysmetria, and dysdiadochokinesia. The cerebellar lesions caused moderate mass effect in posterior fossa with hydrocephalus, and Chiari type I malformation. We performed the suboccipital-retrosigmoid approach, and removed completely the left intracerebellar mass. Symptoms related to elevated intracranial pressure disappeared in a short period postoperatively.

  20. Compensation following bilateral vestibular damage

    2011-12-01

    Full Text Available Bilateral loss of vestibular inputs affects far fewer patients than unilateral inner ear damage, and thus has been understudied. In both animal subjects and human patients, bilateral vestibular hypofunction (BVH produces a variety of clinical problems, including impaired balance control, inability to maintain stable blood pressure during postural changes, difficulty in visual targeting of images, and disturbances in spatial memory and navigational performance. Experiments in animals have shown that nonlabyrinthine inputs to the vestibular nuclei are rapidly amplified following the onset of BVH, which may explain the recovery of postural stability and orthostatic tolerance that occurs within 10 days. However, the loss of the vestibulo-ocular reflex and degraded spatial cognition appear to be permanent in animals with BVH. Current concepts of the compensatory mechanisms in humans with BVH are largely inferential, as there is a lack of data from patients early in the disease process. Translation of animal studies of compensation for BVH into therapeutic strategies and subsequent application in the clinic is the most likely route to improve treatment. In addition to physical therapy, two types of prosthetic devices have been proposed to treat individuals with bilateral loss of vestibular inputs: those that provide tactile stimulation to indicate body position in space, and those that deliver electrical stimuli to branches of the vestibular nerve in accordance with head movements. The relative efficacy of these two treatment paradigms, and whether they can be combined to facilitate recovery, is yet to be ascertained.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    Full Text Available En el presente trabajo se exponen algunas consideraciones sobre diferentes procesos productivos y sus consecuencias sobre el medio ambiente. La disminución del impacto negativo de algunas producciones sobre el medio ambiente es favorable, pero el problema va más allá y de lo que se trata es de la necesidad de una transformación sostenible de las producciones que puedan conducir a una vida agradable y una naturaleza conservada entre otras muchas cuestiones que agobian hoy al mundo. La solución al problema puede ser alcanzada con mayor prioridad en la reducci ón de la fuente primaria de la contaminación, seguida por el reciclaje y el desarrollo de tecnologías limpias. La reducción en la fuente se aplica por los cambios de productos y procesos. El cambio de la fuente se relaciona con la composición o el uso de los productos intermedios y finales, que reduzcan los residuos de producción, su uso o la disposición de los productos. Los cambios de procesos están relacionados con la sustitución de las materias primas de entrada, la modificación de las tecnologías y las mejoras operacionales. Las opciones específicas pueden incluir: el uso de materiales menos tóxicos, el aumento de la automatización, los procedimientos para las operaciones y el mantenimiento, el control de inventario, entre otros.

    Full Text Available En la última década se ha comenzado a prestar atención a las secuelas que producen los episodios de maltrato. En este trabajo se presentan los datos más o menos consistentes con los que contamos en la actualidad, tratando de distinguir entre los efectos de los diferentes tipos de malos tratos sobre el desarrollo psicológico del niño, efectos en la infancia, la edad escolar, la adolescencia y la edad adulta. En lo relacionado con efectos en la infancia se destaca el retraso en el desarrollo que empieza a apreciarse a la edad de un año de vida y que parece aumentar a medida que pasa el tiempo. Se da en todas las áreas comportamentales, siendo la motora la menos afectada. Existen además otros problemas de conducta (ansiedad, impulsividad, distractibilidad, p.e.. En la edad escolar nos encontramos además con retrasos académicos, menor rendimiento en pruebas de inteligencia, probablemente debido a su retraso en el área sociocognitiva. En la adolescencia hay problemas de conducta (conducta agresiva y conducta antisocial. Se ha aceptado tradicionalmente que los efectos a largo plazo del maltrato consistían en que estos sujetos maltrataban a sus hijos cuando llegaban a ser padres, aunque recientemente esto se ha puesto en duda. Se presentan algunos factores protectores y de vulnerabilidad a la transmisión integeneracional del maltrato. Por último, se presenta una reflexión sobre los posibles factores responsables o mecanismos a través de los cuales los malos tratos llegan a producir esas consecuencias. Probablemente son las variables propias de la interacción niño-adulto las principales responsables de esos efectos observados.

    Full Text Available Introduction. In 1814 Giovanni Monteggia first described two cases of fractures of the proximal third of ulna with dislocation of the radial head. These fractures are more common in children than in adults, and mutual Monteggia fracture is a rare complication. This study presents a treatment course of a patient with bilateral Monteggia fracture. Case report. A 55- year-old patient was injured by falling in the yard. Radiography showed bilateral Monteggia fracture type II (by the Badon classification. Operative treatment of fracture was done by a compression plate on the right side and by the zuggurtung technique on the left one. Closed repositioning of the radial head was done on both sides. The patient was wearing a plaster splint for the upper arm for 21 days. After removing the fixation, the function of the elbow was determined by the Broberg Morrey score (BM which was on the right side 45.5 and on the left side 47.5. After the proper physical therapy, four months after the surgery, BM score was 100 on the right side, and 93 on the left one. Conclusion. Surgical treatment and early rehabilitation is the key for the return of good function of both elbows.

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

    Full Text Available In the early twentieth century, the Republican political restructuring in Colombia involved the predominance of government civil buildings over the religious (inherited from colonial rule. However, the largest architectural work in Ibague was the Carmelite church. This dilemma led to the investigation of notarial sources, photographic and cartographic collections, which obtained data were then compared to understand the relationship between architecture and the underlying social dynamics. Thus, was discovered the political, educational and religious structure which intervened in the architectural realization of ideas of that time, consistent that the government delegated in the religious orders the educational tasks necessary for national development, amalgamating political and educative trends with religious, to generate a strategy which publicized the architecture as a symbol of economic development.

    Full Text Available From year to year, an ever increasing number of young professionals with good postgraduate training enter the labor market in Spain. The author discusses the consequences that this economic and sociological trend has for young and oíd workers in the two-fold context of high flexibility of labor markets and frequent, computer-related, technological innovations. While new employees must deal with highly unstable and competitive labor markets, older workers may simply lose their jobs to young replacements. Governments cope with this situation either by reducing the age for retirement (e.g., in Spain and Europe or by helping oíd people accept a second professional opportunity (e. g., in the USA.En los últimos años, son tantos los jóvenes universitarios españoles con buena formación de posgrado y el deseo de un puesto de trabajo satisfactorio que desbordan la capacidad del sistema económico de absorberlos. Las consecuencias de este desfase son diversas, pero en este trabajo se llama la atención sobre la competencia que se da entre los jóvenes empleados, que ha dado lugar a unas condiciones de trabajo leoninas en lo que respecta a horario y a estabilidad en el empleo. Estas condiciones han generado una gran presión sobre los trabajadores de mayor edad, hasta el punto de poner en peligro el mercado laboral para este sector de la población. Sin embargo, en los Estados Unidos la participación de los trabajadores entre 55 y 65 años en la población activa apenas ha descendido en los últimos quince años, lo que supone la existencia de lo que genéricamente se podría llamar «la segunda oportunidad», una opción contrapuesta a la de las prejubilaciones, que parece la opción de España y Europa.

    Full Text Available El tipo de cambio nominal es un elemento clave dentro de la economía, ya que sirve como referencia básica para el intercambio de bienes entre los países, así como para la asignación de recursos productivos entre los distintos sectores económicos que componen la economía del país. En términos generales, las naciones del mundo suelen tener una única referencia cambiaria, sin embargo, bajo condiciones particulares de tensión en la balanza de pagos o severas crisis internas, pueden establecer estructuras cambiarias híbridas o múltiples. El trabajo tiene como objetivo comprender la dinámica de las estructuras cambiarias alternativas, las razones que conllevan a su instauración, así como la experiencia de la historia económica de Venezuela (1960-2013. El establecimiento de referencias cambiarias múltiples en el país suele estar asociado con la merma en la disponibilidad de activos externos, producto de choques negativos en los términos de intercambio o desajustes macroeconómicos financiados a través de la emisión monetaria. El aumento de la prima cambiaria entre el tipo de cambio oficial y el paralelo, con las consiguientes distorsiones en el funcionamiento de la economía nacional, ha sido el detonante principal para unificar el tipo de cambio. En consonancia con la experiencia internacional, la tasa de inflación promedio en los años con tipo de cambio unificado en Venezuela fue significativamente menor (14,5% que en los períodos con dos o más tipos de cambio (28,4%.

    We report a case of bilateral complete failure of adduction following bilateral translid antralethmoidal orbital decompression. We believe the probable mechanism is neuropraxia (temporary dysfunction) of the third cranial nerves' supply to the medial recti, owing to these nerves' occupying an anatomically abnormal position. Partial recovery of adduction occurred over the ensuing six months.

  16. Concurrent bilateral ectopic pregnancy: a rarity

    Full Text Available Bilateral ectopic pregnancy is a rare twin gestation with only a few cases reported in the literature. We report a 30 year old woman without any high risk factor for ectopic pregnancy, who had concurrent bilateral ectopic pregnancy. A 30 year old female presented to the Gynecology emergency department complaining of vaginal bleeding and abdominal pain. The presumptive diagnosis of ruptured left sided ectopic pregnancy was made on basis of clinical findings and ultrasound finings. An emergency laparotomy was done revealed a hemoperitoneum of 1.5 liters, a ruptured left tubal pregnancy with active bleeding and right tubal un-ruptured ectopic was found. A bilateral salpingectomy was performed. Histopathology confirmed presence of chorionic villi in both tubes. In theory, laparoscopic salpingostomy is the best surgical approach in bilateral tubal pregnancy. However, bilateral salpingectomy may be necessary when both tubes are extensively damaged or are actively bleeding. Successful pregnancies have been reported after conservative surgical treatment of bilateral ectopic, but the risk of recurrence is high. Our decision for an emergency laparotomy followed by bilateral salpingectomy was based on the fact that the patient presented with acute abdomen and was haemodynamically unstable and there was extensive bilateral tubal damage. As the incidence of ectopic pregnancies is increasing concurrently with the incidences of pelvic inflammatory disease and use of assisted fertility techniques; it may be that these and ldquo;rare ectopics and rdquo; will become less uncommon.

    Full Text Available La crisis financiera mundial ha vuelto a poner de manifiesto la necesidad de contar con mayores y mejores medidas que actualicen el marco que regula las pautas de elaboración y auditoría de la información financiera publicada por las empresas. De entre esas medidas, el artículo se enfoca en la emisión de la nueva Norma Internacional de Auditoría Revisada y Reeditada sobre materialidad (NIARR 450, que entró en vigor el pasado 15 de diciembre de 2009. En ella, como importante novedad, se establece la necesidad de considerar una serie de factores cualitativos al evaluar la significatividad de aquellas incidencias detectadas en la información financiera que, a pesar de no ser numéricamente significativas, debido a su naturaleza y circunstancias particulares, deben ser corregidas o, por el contrario, reveladas como salvedades en el informe de auditoría. En concreto, se presenta evidencia empírica en torno a la predisposición mostrada por un grupo de auditores de México y España acerca de la utilización efectiva de dichos factores, así como a su opinión sobre las consecuencias que de ello podrían derivarse en ciertos ámbitos de la auditoría. Los resultados obtenidos, aunque en general son positivos de cara a valorar la aceptación de la nueva NIARR 450, en particular muestran diferentes grados de acuerdo con la utilización efectiva de los factores cualitativos de la materialidad entre los auditores de ambos países. De igual forma, estos distintos grados de consenso se manifiestan en su opinión sobre las consecuencias que este hecho produciría sobre el contenido informativo, la utilidad y la comprensibilidad del dictamen de auditoría, así como sobre la fiabilidad, la transparencia y la relevancia de los estados financieros.

    The bilateral filter and its variants such as the Joint/Cross bilateral filter are well known edge-preserving image smoothing tools used in many applications. The reason of this success is its simple definition and the possibility of many adaptations. The bilateral filter is known to be related to robust estimation.

One of the salient features is evidenced by the records of imports and exports of billions of dollars that experienced their peak in 2008 with 7.289 million dollars of trade. However, since 2009 this trade declined due to political confrontations that made to rethink the challenges and strategies in Caracas and Bogota to recover, rather than economic, the political, institutional and even social. This research aims to analyze the causes that led to a stage where it is ob-served a booming in bilateral trade, momentum, maximum and steep drops, but one way or another are needed for its complement. The methodology used in this study was the documentary research. Finally these events are related to the rigors of exchange control in Venezuela, CADIVI, that affect the price of the products that are recorded daily in various transactions made by entrepreneurs and marketers on the Colombian side and by the end 2011 recorded an exchange of 2,193 million.El intercambio comercial entre Colombia y Venezuela ha estado totalmente afectado en los últimos cuatro años.

    Full Text Available We report the case of a 25-year-old male patient who presented with bilateral panophthalmitis as the initial ocular manifestation of dengue fever. The diagnosis was a little confusing as he initially presented with features suggestive of retrobulbar hemorrhage secondary to his very low platelet count, which is a common feature of dengue fever. Ophthalmic complications are usually seen in young adults who often present at the nadir of thrombocytopenia. Ocular findings may include anterior uveitis, vitritis, retinal hemorrhages, retinal vascular sheathing, yellow subretinal dots, retinal pigment epithelium (RPE mottling, foveolitis that is clinically seen as a round subretinal yellowish lesion at the fovea, retinochoroiditis, choroidal effusion, optic disc swelling, optic neuritis, neuroretinitis, and oculomotor nerve palsy. [1] There is only one reported case of unilateral endogenous panophthalmitis due to dengue fever. Hence, clinicians and ophthalmologists have to be aware of this vision-threatening complication of dengue for early recognition and prompt treatment to save the vision of these young patients and prevent morbidity.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing’s syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88–100% and 67–100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50–70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    A nineteen years old woman with ambiguous external genitalia was studied. This condition had been previously identified as a newborn, but her parents refused medical attention and it was reared as a girl. At 12-years, she began spontaneous mammary development, appearing pubic and axillary hair, and clitoral enlargement. The menarche occurred at 15-years and it was followed by irregular periods. Physical examination, showed absence of hirsutism and acne, normal mammary development equivalent to grade V of Tanner. The external genitalia showed fused labio-scrotal folds with an small introitus. The urethral meatus was absent and was later located inside the introitus. There was a big phallus similar to an adult penis with a normal glans, flexed by a chordee. Hormonal determinations discarded congenital adrenal hyperplasia. The karyotype was 46,XX and testosterone levels were in adult male range. Pelvic ultrasonography disclosed a normal uterus and both gonads in confirmed by laparoscopy identifying bilateral ovotestis. Testicular tissue was removed and plastic reconstruction of female genitals was done. PMID:9528217

    Full Text Available Este artículo tiene como propósito construir y validar un modelo integrado de relaciones para el fomento de la creación de valor percibido por los egresados en el ámbito universitario. Con esta finalidad, se aplican las directrices del marketing de relaciones al análisis de la gestión educativa y al encuentro de servicio entre el profesor y sus estudiantes, mediante un estudio de campo realizado a 1000 egresados universitarios de dos universidades españolas. La técnica empleada fue el análisis factorial confirmatorio y el contraste del modelo estructural planteado a nivel teórico, con LISREL 8.80. Las conclusiones de este estudio suponen un avance en la literatura sobre educación superior, al corroborarse las relaciones planteadas, escasamente analizadas en este ámbito con anterioridad. Así, los resultados muestran que variables como la confianza, la calidad de la interacción alumnoprofesor, y la imagen de la Universidad influyen positivamente en la percepción del valor que ésta aporta, el cual, a su vez, afecta al nivel de satisfacción del egresado, contribuyendo a la formación de lealtad hacia la institución.

    Full Text Available The EU is a world economic power and a major trading partner for most countries. All the time, this region has been interested and has acted towards a free and fair trade. The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    Extramedullary plasmacytoma (EMP) is usually seen in the head and neck regions and in the upper respiratory, gastrointestinal, and central nervous systems. Testis is a rare site for EMP, and bilateral synchronous testicular plasmacytoma occurring as an isolated event at initial presentation has been reported only once previously. We present herein the second such report in a 70-year-old man who underwent bilateral orchidectomy. PMID:27034568

    Full Text Available Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral anophthalmia and septo-optic dysplasia.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    Full Text Available We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

La filosofía de la razón vital de Ortega se fundamenta en el concepto de vida humana como realidad radical y principio interpretativo universal, y por esta razón se presenta desde el principio como una filosofía hermenéutica de la vida y no como una reducción hacia la conciencia trascendental. Esta hermenéutica se practica especialmente en el ámbito del arte. Pero para Ortega todo texto es hermenéutico y necesita por tanto la interpretación, porque ningún texto posee en sí mismo su verdad.

Há pouco tempo, as grandes cidades brasileiras foram invadidas por uma nova mania: as paletas mexicanas, que, na verdade, não são “tão mexicanas”. Esses sorvetes apresentam qualidades organolépticas marcantes, em virtude, entre outros fatores, ao alto teor de açúcar e, em alguns casos, de gorduras. A concepção gourmetizada e natural dessa iguaria, seu custo e as propriedades nutricionais são peculiares e, aparentemente, um modismo. Esse trabalho teve como objetivo conhecer a composição desses produtos, a partir das informações nutricionais contidas nos sites das empresas produtoras, bem como as suas peculiaridades e concepções. Apesar da conotação natural e gastronômica, alto valor calórico, gorduras (especialmente na versão recheada sabor brigadeiro e elevadas quantidades de açúcares, foram encontrados, em média, por unidade: 207,2 Kcal; 38,4g de carboidratos; 3,9g de proteínas e 5,3g de gorduras. Uma rica ênfase na cultura mexicana, religiosidade e identidade visual marcante foram identificadas nos sites dos produtos pesquisados.

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

  6. Chronic Bilateral Tibial Stress Fractures with Valgus Treated with Bilateral Intramedullary Nailing: A Case Report

    Steven K Dailey

    2014-01-01

    Full Text Available Introduction: Stress fractures are overuse injuries most commonly seen in athletes, military recruits, and individuals with endocrine abnormalities. It has been demonstrated that chronic cases of anterior tibial stress fractures refractory to conservative management respond well to intramedullary nailing. To our knowledge, only one report has been published concerning patients with bilateral tibial stress fractures treated with bilateral intramedullary nailing. All patients in the series were high-level athletes. We present the case of a non-athletic patient with chronic bilateral tibial stress fractures and associated deformity successfully treated with bilateral intramedullary nails. Case Report: A 23-year-old Caucasian female full-time student presented with chronic bilateral shin pain for approximately five years. She had failed an extensive regimen of conservative management. She was diagnosed with chronic bilateral tibial stress fractures based on history, physical examination, and radiologic findings. She subsequently underwent sequential intramedullary nailing of her tibiae. Both tibiae were in valgus alignment; however, this did not preclude nail placement. The nails deformed upon insertion into the sclerotic canals to conform to the deformation. Post operatively the tibiae united and patient was relieved of her symptoms. Conclusion: Bilateral intramedullary nailing of chronic bilateral tibial stress fractures should be considered as a treatment option for all patients, not just high-level athletes, who fail a trial of conservative management. Additionally, mild to moderate tibial malalignment does not necessarily preclude tibial nailing as the smaller nails placed in sclerotic canals will likely deform on insertion and conform to the canal.

    Currently, no consistent evidence-based guidelines for the management of synchronous bilateral breast cancer (SBBC) exist and it is uncertain how presenting with SBBC affects patients' prognosis. We conducted a review of studies analyzing the association between SBBC and prognosis. The studies...... that reported adjusted effect measures were included in meta-analyses of effect of bilaterality on breast cancer mortality. From 57 initially identified records 17 studies from 11 different countries including 8,050 SBBC patients were included. The quality of the studies varied but was generally low with small...... sample sizes, and lack of consistent, detailed histo-pathological information. When doing meta-analysis on the subgroup of studies that provided adjusted effect estimates on breast cancer mortality (nine studies including 3,631 SBBC cases), we found that bilaterality in itself had a negative impact...

    Pneumolabyrinth describes a condition with entrapped air in the labyrinth and usually occurs in temporal bone fractures that involve the otic capsule. While sporadic cases of bilateral pneumolabyrinth have been reported, cases lacking head trauma are very rare. We report the case of a 43-year-old man who had sudden hearing loss bilaterally after blowing his nose at an interval of 1 year. Although conservative management for the right ear and exploratory tympanotomy with sealing of the possible site of perilymphatic leakage in the left ear were performed, hearing outcome was poor in both ears. To our knowledge, this is the first case of bilateral pneumolabyrinth occurring as a result of nose blowing. PMID:26771019

Physical examination revealed edema in the tympanic membrane and external ear canal, and pain by palpation in the mastoid area bilaterally. There was no nystagmus, and the rest of the physical examination was otherwise normal. Temporal bone high resolution computed tomography (CT showed a lesion causing erosion in the mastoid cortex, tegmen tympani, ossicles, and in the bone covering the sigmoid sinus bilaterally. There was also erosion in the superior semicircular canal and petrous bone on the left side. Cortical mastoidectomy was performed under general anesthesia. Histopathologic examination of the tissue revealed Langerhans cell histiocytosis (LCH. In this paper a case with LCH, presenting with bilateral mastoid involvement which has been rarely reported in the literature, is discussed with the existing literature.

    Choroidal osteoma is a an extremely rare (especially located bilaterally), benign, intraocular tumor, the type of choristoma. It occurs between 2-3 decades of life, women are particularly vulnerable. The main complication in 1/3 cases is a subretinal neovascularization which may cause bleeding. The gradually progressive decalcification develops within the tumour over time, which causes atrophy of the retinal pigment epithelium and Bruch's membrane deformity. The article presents a case of a 26-year-old woman with bilateral choroidal osteoma complicated by subretinal hemorrhage; the diagnosis was based on clinical examination (biomicroscopy and indirect ophthalmoscopy) as well as specialised tests including: ultrasonography, optical coherence tomography, and fluorescein angiography.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

  2. Fast and Provably Accurate Bilateral Filtering.

    Science.gov (United States)

    Chaudhury, Kunal N; Dabhade, Swapnil D

    2016-06-01

    The bilateral filter is a non-linear filter that uses a range filter along with a spatial filter to perform edge-preserving smoothing of images. A direct computation of the bilateral filter requires O(S) operations per pixel, where S is the size of the support of the spatial filter. In this paper, we present a fast and provably accurate algorithm for approximating the bilateral filter when the range kernel is Gaussian. In particular, for box and Gaussian spatial filters, the proposed algorithm can cut down the complexity to O(1) per pixel for any arbitrary S . The algorithm has a simple implementation involving N+1 spatial filterings, where N is the approximation order. We give a detailed analysis of the filtering accuracy that can be achieved by the proposed approximation in relation to the target bilateral filter. This allows us to estimate the order N required to obtain a given accuracy. We also present comprehensive numerical results to demonstrate that the proposed algorithm is competitive with the state-of-the-art methods in terms of speed and accuracy. PMID:27093722

  8. "Ostrich sign" indicates bilateral vertebral artery dissection.

    2012-11-01

    Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

    Full Text Available El artículo de Emmanuel Housset implica un esfuerzo de rehabilitación del concepto «persona» para la filosofía contemporánea y la fenomenología. Para ello el autor busca mostrar cómo poco a poco «persona» tomó otra significación que la de «personaje» o sujeto de derecho. Es en autores como san Agustín y santo Tomás de Aquino que se halla un acceso diferente que pone el énfasis más bien en su carácter relacional y responsivo de la persona, antes que en su dimensión autónoma y autotélica. Tal dimensión aparece, según Housset, junto con la idea de persona como creatura y en oposición a la de individuo racional dueño de sí. La dimensión afectiva, la personalidad despertada por las diversas figuras de la alteridad son algunas de las dimensiones de la persona que examina el autor a partir del examen de la carne, las pasiones, la memoria, la historicidad y el amor alteridad.Emmanuel Housset's paper is an effort to revitalize the concept of 'person' for contemporary philosophy and phenomenology To this end the author looks to show how little by little the understanding of 'person' took on a different meaning to that of 'character' or "right bearing individual". It is in authors such as St. Augustine and St. Thomas Aquinas that a different approach is found, one that puts emphasis on the relational and responsive character of a person, rather than on the autonomous and auto telic dimension. According to Housset, such a dimension appears together with the idea of the person as a creation, and in opposition to the idea of the rational individual, that is his own master. The emotional dimension and the personality that is awoken by the many figures of alterity are some of the dimensions of the person that the author analyzes, based on examining the flesh, passions, memory historicity and love.

Sin embargo, desde un enfoque sistémico puede verificarse que la gran mayoría de los desastres se origina en los países en desarrollo (entre ellos los latinoamericanos, siendo las pérdidas en ellos significativamente más altas que en los países industrializados. Bajo esta postura los desastres no son sólo naturales sino socio- naturales, enfatizando la estrecha relación de causalidad entre modelos de desarrollo y urbanización y procesos de generación de riesgos, al incrementar la vulnerabilidad de los sectores más desprotegidos. El desastre pone en evidencia así una situación (la pobreza y segregación urbana ya existente, pero no considerada hasta el momento de la catástrofe. Frente a este panorama el desastre aparece como oportunidad que precipita tres catalizadores de políticas habitacionales: tierra, asistencia técnica y financiamiento, incrementando la celeridad y la creatividad de las respuestas. El interrogante que surge es por qué esperar el desastre para ponerlos en marcha, cuando ninguno de ellos es estrictamente dependiente de la situación de riesgo, sino sujeto de luchas de poder.

These signs and symbols have usually been considered simply as mere elements to validate the charters. However, these alements were useful as a mean of visual communication between the high classes, able to generate charters, and the rest of medieval society—the majority illiterate— who received those charters. Because of their inability of understand an alphabetical code, they needed the graphic help to comprehend the message. Besides this, the article deals with non diplomatic signs and their function.

    Obturator hernia (OH), a rare type of hernia, is associated with high morbidity and mortality. Diagnosis is often delayed as clinical symptoms are typically non-specific. OH is frequently associated with other occult inguinopelvic herniae. Early diagnosis is vital to decrease morbidity and mortality. We report the case of a 75-year-old woman who presented to the surgical outpatients' department with non-specific bilateral groin pain radiating to the thighs. CT of the pelvis demonstrated bilateral OH with no radiological evidence of bowel obstruction. Semiurgent elective laparoscopic total extraperitoneal mesh repair was performed. Intraoperative findings confirmed bilateral obturator herniae as well as incidental bilateral femoral herniae. This case highlights the need for a high index of suspicion for such concomitant hernias that, in the presence of OH, may only be identified intraoperatively. PMID:27113790

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

El estudio, con un diseño descriptivo longitudinal mediante cuestionarios, se llevó a cabo sobre una muestra de 101 adolescentes (63 varones y 38 mujeres que fueron estudiados en 3 ocasiones: a los 13, 15 y 18 años de edad. Los resultados mostraron tres grupos de adolescentes en función de las trayectorias seguidas por su consumo de sustancias: consumo bajo, consumo ascendente y experimentación precoz. La comparación entre estos tres grupos indicó un mejor ajuste psicológico en la adolescencia tardía entre los varones y mujeres del grupo de experimentadores, mientras que los problemas de conducta fueron más frecuentes entre los incluidos en el grupo de consumo ascendente. Por otra parte, los análisis de regresión señalaron que el consumo moderado de sustancias en la adolescencia temprana estaba relacionado con una autoestima más alta y con menos problemas emocionales al final de la adolescencia, pero no con más problemas externos.

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    2009-01-01

    Upper extremity hemiparesis is the most common post-stroke disability. Longitudinal studies have indicated that 30-66% of stroke survivors do not have full arm function 6 months post-stroke. The current gold standard for treatment of mild post-stroke upper limb impairment is constraint-induced therapy but, because of the inclusion criteria, alternative treatments are needed which target more impaired subjects. Bilateral arm training has been investigated as a potential rehabilitation intervention. Bilateral arm training encompasses a number of methods including: (1) bilateral isokinematic training; (2) mirror therapy using bilateral training; (3) device-driven bilateral training; and (4) bilateral motor priming. Neural mechanisms mediating bilateral training are first reviewed. The key bilateral training studies that have demonstrated evidence of efficacy will then be discussed. Finally, conclusions are drawn concerning clinical implications based on the reviewed literature. PMID:19517519

    Full Text Available Consecuencias del efecto Bullwhip según distintas estrategias de gestión de la cadena de suministro: modelado y simulación = Bullwhip Effect Consequences according to Different Supply Chain Management Strategies: Modelling and SimulationAbstract: El efecto Bullwhip es uno de los principales causantes de las inestabilidades en el proceso de gestión de demanda que se producen a lo largo de la cadena de suministro. El presente artículo expone un modelo capaz de recrear diferentes escenarios para la gestión de demanda en una cadena de suministro determinada, con independencia del número de niveles definidos en la cadena de suministro considerada. El modelo, realizado utilizando la metodología de la dinámica de sistemas, incorpora las variables necesarias para simular dicho proceso de gestión de demanda, como por ejemplo: niveles de inventario, órdenes de reabastecimiento, fabricación, previsiones u otras. Se muestra la utilidad del modelo propuesto, comparando los resultados que ofrecen dos escenarios diferentes, como son los representados por una cadena tradicional y el de una cadena reducida. = The Bullwhip effect is one of the main causes of instability in the management demand process along the Supply Chain. We introduce a model which is able to reproduce different Supply Chain Management Scenarios within a determinate Supply Chain with whichever the levels of this one. The model has been built using Systems Dynamics Methodology and incorporates the main variables which are required for simulating the Management Demand Process (Inventory levels, Replenishment orders, manufacturing process, forecasting etc.. This paper demonstrates the utility of the proposed model comparing the results offered by two different scenarios namely Traditional supply chain and Reduced supply chain.

    Full Text Available El silencio en el mundo laboral tiene importantes consecuencias en el proceso de toma de decisiones y puede interferir con la resolución de problemas. La literatura al respecto es escasa y en nuestro país prácticamente inexistente. Este artículo pretende explorar las razones por las que los empleados no expresan sus opiniones en el trabajo, así como sus consecuencias, adoptando el formato de revisión bibliográfica. Los empleados se muestran muy interesados en el futuro de su puesto de trabajo, en mantener buenas relaciones y en estar bien considerados. Esto puede provocar inhibición debido a una desvinculación, al miedo o a la cooperación. Todos los artículos utilizados en esta revisión provienen de revistas de economía y gestión inglesas y americanas, lo cual subraya la importante necesidad que estudios que exploren el silencio dentro de la enfermería en España.Silence in the workplace may have important consequences on the decision-making process and it may interfere with the solving-problems ability. There is a lack of evidence explorin this topic. Therefore, this literature review explores the reasons and implications of keeping silent in the workplace. The aim of this paper is to explore the reasons and the implications that silence has within the workplace. Employees are very interested in their workplace’s future, in keeping good relationships, and in being well considered, and it is precisely this position that is making them more inhibited in the workplace. Disengagement, fear and co-operation are the main reasons why people remain silent among employees in the workplace. All the articles used in this paper come from English and American business and management journals. This issue highlights the need of nursing research about the topic of discussion in Spain.

    Full Text Available Purpose: To report the clinical, confocal scan, and histopathologic features of Nocardia keratitis in a patient who developed bilateral infection following photorefractive keratectomy (PRK. Case Report: A 23-year-old woman underwent bilateral PRK for low myopia. On postoperative day 3, dense central stromal infiltrates were noticed in both eyes. Empirical antibiotic therapy was initiated which was converted into specific therapy after a definite diagnosis was made based on clinical features and confirmed by confocal scan and histopathologic findings. Clinical and confocal scan features were consistent with the diagnosis of Nocardia keratitis, and topical 2% amikacin eye drops were started. Because of poor response to medical therapy, lamellar keratectomy was performed in both eyes which shortened the treatment course. Histopathologic examination reconfirmed the initial diagnosis. Conclusion: Familiarity with clinical and confocal scan features facilitates early diagnosis of Nocardia keratitis leading to proper management and hence a rapid therapeutic response.

    2012-04-01

    Full Text Available 【Abstract】There is a dearth of case reports de-scribing simultaneous bilateral patellar tendon ruptures in the medical literature. These ruptures are often associated with systemic disorders such as lupus erythematosus or chronic steroid use. The author describes a case of a 24-year-old man who sustained traumatic bilateral patellar ten-don ruptures without any history of systemic disease or steroidal medication. We repaired and reattached the rup-tured tendons to the patella and augmented our procedure with allogeneic tendon followed by wire loop reinforcement. One year after operation, the patient regained a satisfactory range of motion of both knees with good quadriceps strength and no extensor lag. The recurrent microtrauma from a history of intense sports activity and a high body mass index may have played an important role in this trauma event.

    2009-11-01

    Full Text Available We present the case of a 45-year-old female who presented multiple times to the emergency department with acute low back pain and was subsequently diagnosed with bilateral psoas muscle abscess. Psoas abscess is an uncommon cause of acute low back pain that is associated with high morbidity and mortality. The onset of symptoms is frequently insidious and the clinical presentation vague. Proper diagnosis requires vigilance of the physician to recognize signs in the history and physical examination that are suggestive of a potentially serious spinal condition and initiate further workup. While most patients with acute low back pain have a benign etiology, this case report demonstrates the challenge of diagnosing a patient with bilateral psoas abscess who had few known risk factors and symptoms typical of mechanical low back pain.[West J Emerg Med. 2009;10(4:288-291.

    To determine the frequency and causes of bilateral ocular trauma. All patients coming to the hospital with bilateral eye trauma and requiring admission were recruited into the study. The details of patients demographics, risk factors, ocular examination, treatment offered and final visual acuity were noted and described as frequency and percentages. Out of a total of 1551 patients of hospitalized ocular trauma, 46 (2.9%, 92 eyes) had bilateral ocular trauma. The majority (54.3%) were due to landmine blast injuries followed by dynamite blast in 10.8%, coalmine blast and firearm injury in 6.5% each. Pressure cooker explosion and road traffic accident was the cause in 4.3% each. Gas cylinder and automobile battery explosion, alkali and acid burn, assault and incidental trauma occurred in 2.1%. Sixty three percent were between 16 and 40 years of age. Males were affected in 93.4%. Corneal and / or scleral repair was done in 58.6%, conjunctival and or corneal foreign body removal in 26% and extracapular cataract extraction with intraocular lens implantation in 16.3%. The visual acuity was in the range of 6/60 and perception of light in 54.3%, while in 21.7%, there was no perception of light at the time of admission. Due to severity of injury, the final visual acuity was poor and only 28.2% regained vision between 6/18 and 6/60. In this series, landmine, dynamite and coalmine blasts were the major causes of bilateral ocular trauma. Victims were usually young males. Due to severity of ocular trauma, majority had poor visual outcome. (author)

    The well-known bilateral filter is used to smooth noisy images while keeping their edges. This filter is commonly used with Gaussian kernel functions without real justification. The choice of the kernel functions has a major effect on the filter behavior. We propose to use exponential kernels with L1 distances instead of Gaussian ones. We derive Stein's Unbiased Risk Estimate to find the optimal parameters of the new filter and compare its performance with the conventional one. We show that t...

    2015-12-01

    Full Text Available Aspergillus endophthalmitis is a devastating inflammatory condition of the intraocular cavities that may result in irreparable loss of vision and rapid destruction of the eye. Almost all cases in the literature have shown an identified source causing aspergillus endophthalmitis as a result of direct extension of disease. We present a rare case of bilateral aspergillus endophthalmitis. A 72-year-old woman with a history of diabetes mellitus, congenital Hirschsprung disease, and recent culture-positive candida pyelonephritis with hydronephrosis status post-surgical stent placement presented with difficulty opening her eyes. She complained of decreased vision (20/200 with pain and redness in both eyes – right worse then left. Examination demonstrated multiple white fungal balls in both retinas consistent with bilateral fungal endophthalmitis. Bilateral vitreous taps for cultures and staining were performed. Patient was given intravitreal injections of amphotericin B, vancomycin, ceftazidime, and started on oral fluconazole. Patient was scheduled for vitrectomy to decrease organism burden and to remove loculated areas of infection that would not respond to systemic antifungal agents. Four weeks after initial presentation, the fungal cultures revealed mold growth consistent with aspergillus. Patient was subsequently started on voriconazole and fluconazole was discontinued due to poor efficacy against aspergillus. Further workup was conducted to evaluate for the source of infection and seeding. Transthoracic cardiogram was unremarkable for any vegetation or valvular abnormalities. MRI of the orbits and sinuses did not reveal any mass lesions or bony destruction. CT of the chest was unremarkable for infection. Aspergillus endophthalmitis may occur because of one of these several mechanisms: hematogenous dissemination, direct inoculation by trauma, and contamination during surgery. Our patient's cause of bilateral endophthalmitis was through an

    Brodie's abscess is a form of subacute osteomyelitis, which typically involves the metaphyses of the long tubular bones, particularly in the tibia. The diagnosis is usually made incidentally, as there are no accompanying symptoms or laboratory studies. Bilateral involvement at the proximal tibia is unusual. However, orthopaedic surgeons should be aware of this entity, as it may present without symptoms. Checking the contralateral limb for concomitant Brodie's abscess is recommended.

    2008-06-05

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

    We report here a case study of a rare neurological patient with bilateral brain damage encompassing a substantial portion of the so-called “limbic system.” The patient, Roger, has been studied in our laboratory for over 14 years and the current article presents his complete neuroanatomical and neuropsychological profiles. The brain damage occurred in 1980 following an episode of herpes simplex encephalitis. The amount of destroyed neural tissue is extensive and includes bilateral damage to core limbic and paralimbic regions, including the hippocampus, amygdala, parahippocampal gyrus, temporal poles, orbitofrontal cortex, basal forebrain, anterior cingulate cortex, and insular cortex. The right hemisphere is more extensively affected than the left, although the lesions are largely bilateral. Despite the magnitude of his brain damage, Roger has a normal IQ, average to above average attention, working memory, and executive functioning skills, and very good speech and language abilities. In fact, his only obvious presenting deficits are a dense global amnesia and a severe anosmia and ageusia. Roger's case presents a rare opportunity to advance our understanding of the critical functions underlying the human limbic system, and the neuropsychological and neuroanatomical data presented here provide a critical foundation for such investigations.

  19. Bilateral femoral neck fractures following pelvic irradiation

    International Nuclear Information System (INIS)

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

  1. Bilateral spontaneous rupture of 'hale' kidneys

    International Nuclear Information System (INIS)

    A rare case of spontaneous bilateral rupture of the kidneys, occurring consecutively over a one-year period in a young male patient with 'hale' kidneys until then, is described. The patient's past history and thorough examination performed do not justify to assign the case under the heading of some of the etiological factors as the underlying cause of spontaneous kidney rupture. The literature survey on spontaneous bilateral non-tumor ruptures of kidneys shows that over a 20-year period, only 3 cases of bilateral spontaneous ruptures have been reported. It is pointed out that panarteritis nodosa followed by hemorrhagic fever with renal syndrome is the commonest underlying cause of such ruptures. Clinically spontaneous ruptures become manifest with emergency condition presenting severe renal colic, impaired to serious general condition, often with acute abdomen and hemodynamic breakdown, and no past history evidence of renal disease or injury. In the initial phase diagnosing is not always easy; it is usually made on the ground of physical examination and the full range of imaging studies used in urological practice and during operative treatment. Emphasis is laid on the fact that the imaging methods are not invariably sufficient to identify the exact etiological factor giving rise to such a severe condition, but nevertheless these methods have an essential practical bearing on diagnosing a rupture.

  2. A case misdiagnosed as bilateral abducens palsy

    International Nuclear Information System (INIS)

    A 66-year-old male was admitted to our neurosurgical floor because of double vision and gait disturbance. Neurological examinations revealed bilateral 6th nerve palsy with both eyes pointing toward the midline. Initially, using a tentative diagnosis of intracranial mass lesions, especially localized at the base of the skull, computerized tomography of the head, cerebral angiography, orbital venography, and metrizamide CT cisternography were performed; the findings were normal. An orbital CT scan showed an enlargement of the bilateral medial rectus muscles, and the thyroid functions of T3 and T4 and the T3 uptake were all elevated, which was compatible with the diagnosis of Graves' disease. The limitations of both eyeballs were considered to be due not to the 6th nerve palsy, but to the hypertrophy of the bilateral medial rectus muscles. We neurosurgeons should recall Graves' disease as well as intracranial lesions, cerebrovascular disease, and post-traumatic sequelae when examining a patient who presents limitations of external ocular movement.

    Full Text Available Nasolabial cysts are painless, submucosal, non-odontogenic jaw cysts presenting as soft tissue swellings in the maxillary anterior mucolabial fold lateral to midline, leading to elevation of nasal ala. Present case documents bilateral nasolabial cysts in a 69-year-old Asian female patient. In the present case, extraoral swelling of maxillary lip and elevation of nasal ala was observed on right side of the face. Intraorally, soft and fluctuant bilateral cysts were observed. Straw-colored fluid was aspirated from the right cyst. Radiographically, erosion of bone in a "cupping" fashion was observed in the region of left cyst. The cysts were enucleated using intraoral approach. Histopathology of the right-sided cyst revealed a cystic cavity lined by stratified squamous cells along with a few mucosal cells. At few places, stratified squamous and pseudostratified columnar epithelia with many cilia and goblet cells were also evident. Capsule was loosely arranged with fibrous tissue and chronic inflammatory infiltrate. Left-sided cystic specimen showed two or more layered stratified squamous lining epithelium with thin capsule. Diagnosis of bilateral nasolabial/nasoalveolar cysts was confirmed.

    Full Text Available This article focuses on issues related to the identification and investigation of the lymph node metastases with bilateral breast cancer. The presence of metastases in the lymph nodes determines the stage of the disease, and introducing a form of tumor progression, characterizes the course and prognosis for the future in a specific patient. Thus, the identification of possible morphological and immunohistochemical characteristics of the tumor tissue and their comparison with the frequency and severity of regional lymph nodes would help to solve the problem of the identification of prognostic factors and markers associated with the risk of nodal metastasis in bilateral breast cancer. This work is relevant due to the fact that the literature on this issue to date are treated ambiguously, and answers to many questions, unfortunately, no.The authors performed a morphological study of the tumor tissue from 600 patients suffering from unilateral and bilateral breast cancer. To avoid false results were studied only cases corresponding to the histological type of invasive carcinoma of non-specific type. The study found that a greater number and a greater percentage of the affected lymph node metastases were observed in patients with bilaterally synchronous tumors. The patients of this group of metastatic lymph nodes was detected more frequently in the presence of infiltrative component of three or more types of structures with the presence of these discrete groups of tumor cells, and the observed maximum degree of inflammatory infiltration of the tumor stroma. In the group of patients with unilateral breast cancer nodal metastasis often detects when triple negative molecular genetic type of the lesion, with large amounts of tumor site, in the presence of infiltrative component of three or more types of structures with the obligatory presence of these microalveolar structures and discretely spaced groups of tumor cells and the highest severity of

    Full Text Available Durante más de una década España optó por un modelo de crecimiento desequilibrado en el que el sector inmobiliario ocupó un lugar muy destacado. La sociedad española percibe ahora con mayor claridad las consecuencias presentes y futuras del colapso de la burbuja especulativa inmobiliaria. Consecuencias económicas, territoriales, ambientales, sociales y políticas. Desde las relacionadas con la excesiva dependencia de la actividad económica y el empleo al sector de la construcción residencial, hasta la desaparición irreversible de referentes de nuestra historia y cultura colectivas, pasando por el desarrollo de episodios de «captura de políticas», en especial en la escala local y regional. Un dilatado proceso que ha propiciado la corrupción del urbanismo y un incremento de episodios de mala política donde la reputación de España ha quedado muy afectada. Estas páginas se dedican al análisis de las causas que explican el modelo inmobiliario español y, sobre todo, de las consecuencias, subrayando la gran importancia de los contextos sociales, políticos e institucionales.

    The paper examines the impact of two main instruments of economic diplomacy — regional integration and commercial diplomacy on export flows among African states. We test whether there is any evidence of a trade-off or complementary interaction between these two instruments in trade facilitation. We...... compare the effects of these two instruments of economic diplomacy on bilateral trade by employing a gravity model for 45 African states over the period 1980-2005. The results show that bilateral diplomatic exchange is a relatively more significant determinant of bilateral exports among African states...... that there exists a trade-off between regional integration and commercial diplomacy in facilitating exports or a lack of complementarity between these two instruments of economic diplomacy....

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

    Full Text Available We present a rare case of bilateral pseudoexfoliative deposits on both intraocular lens (IOL implants in an 83-year-old woman with no other associated pathology, 5 years after cataract surgery. Pseudoexfoliation syndrome is the most common cause of secondary open-angle glaucoma worldwide and these deposits are usually found on the natural lens. The fact that pseudoexfoliative deposits have been found on IOL implants implies the need for a thorough examination in pseudophakic patients, for it could be the only sign of secondary glaucoma.

    1999-12-01

    Full Text Available Metropolitan Santiago is one of the many Latin American cities which has been developed according to a spread model of urbanisation. This pattern has caused at least two types of consequences: economic and physical ones. The former is shown in the speculation of land value at the rural fringe of the metropolitan area which has low prices, these have suddenly increased after the normative changes in the land use, from rural to urban. The later shows location of massive low-income housing and commercial malls regardless connection to the urban fabric and spatial shaping of the existing city. This results in a chaotic urban form resembling a "patchwork".This paper reviews the scope of a Chilean policy instrument called "Plan Regulador" used to control physical urban growth, particularly sprawled on the fringe of the city. It is believed that as a consequence of this Plan, normative procedures are not good enough for achieving its objectives. Conversely, urban form appears to be a result of a profitability plan made by private developers. Given the weakness of this instrument, some recommendations related to spatial models are suggested to incorporate to or complement the "Plan Regulador"./ El Plan Regulador Comunal es el instrumento normativo de planeación urbanística chilena, cuya formulación pretende regular en el ámbito comunal básicamente los siguientes aspectos: los usos de suelo, las condiciones de edificación y subdivisión del suelo, la red vial estructurante y los limites urbanos.Se cree que este instrumento es imperfecto toda vez que no incorpora en la normativa una dimensión clave del urbanismo: la morfología urbana, entendida como el sistema espacial tridimensional de la ciudad. Por el contrario, el análisis empírico demuestra que factores como la forma urbana son respuestas del libre juego de fuerzas económicas y sociales modeladoras del espacio. En consecuencia, lo que domina es un patrón de urbanización en vez de un

El acceso a nuevos documentos ha permitido iluminar de mejor manera los motivos del viaje: luego de su renuncia a la Acción Católica, es becado por Mons. Edwin O'Hara para ir a estudiar por un año a la Escuela de Trabajo Social de la Universidad Católica de Washington. El viaje le permite, además, tomar contacto con diversas obras sociales de la Iglesia de EE. UU y de Canadá, profundizar su estudio en la doctrina social de la Iglesia y sus aplicaciones prácticas, y proyectar dos de sus obras sociales más conocidas: el Hogar de Cristo y la ASICH. Finalmente, el contacto con uno de los países más desarrollados del mundo, le inspira en su ministerio sacerdotal a predicar que «la materia no basta» y la centralidad de «la visión de fe».This article shows the impact and the consequences of St. Alberto Hurta-do's trip to the United States in 1945. Access to new documents has shed further light on the reasons for the trip: after he renounced the Catholic Action, Mons. Edwin OHara gives him a scholarship to study at the Catholic University School of Social Work in Washington. The trip also allows him to get involved in several social works of the U.S. and Canadian Church, deepen his study of the Church's social doctrine and its practical applications, and plan two of his best-known social works: Hogar de Cristo and ASICH. Finally, contact with one of the world's most developed countries inspires him in his priestly ministry to preach that «what is material is not enough» and the centrality of the «vision of faith».

    Full Text Available Este trabajo tiene como objetivo analizar normativamente los discursos del colonialismo y el postcolonialismo como campos de investigación de la administración internacional. Los acercamientos teóricos postcoloniales critican las representaciones euro céntrico y occidental del mundo no-occidental y llaman la atención al conocimiento que claman tener del no occidente. Los acercamientos postcoloniales a la administración internacional también tratan de los supuestos y limitaciones del discurso administrativo occidental hecho desde un contexto no occidental. Los diferentes enfoques analíticos de los estudios postcoloniales demuestran que la producción y transferencia del conocimiento de la administración internacional tiene consecuencias materiales para los negocios no occidentales. Explícitamente, la agenda de la investigación postcolonial guiada por el orientalismo requiere de un involucramiento político y ético continuado con las consecuencias epistemológicas y materiales de la investigación en administración internacional.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A neuralgia do nervo trigêmeo é uma condição intensamente dolorosa, caracterizada por surtos de dor lancinante e súbita, tipo choque, com duração de poucos segundos a dois minutos e geralmente unilateral. Sua incidência anual é de cerca de 4,3 em 100.000 na população geral, tendo manifestação bilateral em apenas 3% desses casos. O objetivo deste artigo foi descrever um caso raro de neuralgia do trigêmeo primário bilateral. RELATO DO CASO: Paciente de 61 anos, maranhense, casada, do lar, com antecedente de hipertensão arterial e há seis anos com queixa de dor intensa em V2-V3 à esquerda, com duração de 5 a 10 segundos, em região lateral do nariz e mandibular, com piora ao falar, mastigar e com diminuição da temperatura. Já havia utilizado clorpromazina (3 mg a cada oito horas e carbamazepina (200 mg a cada oito horas durante seis meses sem alívio da dor. Ao exame físico apresentava alodinia térmica e mecânica em regiões de V2-V3. Estava em uso de gabapentina (1.200 mg ao dia com alívio parcial da dor. Foi então aumentada a gabapentina para 1500 mg ao dia e introduzida amitriptilina 12,5 mg à noite. Evoluiu com dor leve e esporádica com diminuição da intensidade da dor ao longo de 10 meses de tratamento, sendo reduzida progressivamente a gabapentina para 600 mg ao dia e mantida a amitriptilina 12,5 mg ao dia. Após um ano, começou a apresentar dor de característica semelhante em região mandibular à direita, tendo melhorado com aumento de gabapentina para 900 mg ao dia. Não apresentava exames alterados de tomografia ou ressonância magnética de encéfalo. CONCLUSÕES: A carbamazepina é o fármaco de primeira escolha para tratamento de neuralgia trigeminal, porém a gabapentina tem sido cada vez mais utilizada como primeira medida farmacológica ou em casos refratários à terapia convencional.JUSTIFICATIVA Y OBJETIVOS: La neuralgia del nervio trigémino es una condici

    Full Text Available This is a report of one case of bilateral acetabular rim fracture in association with femoroacetabular impingement (FAI, which was treated with a hip arthroscopic procedure, performing a partial resection, a labral reinsertion, and a subsequential internal fixation with cannulated screws. Up to date, there are in the literature only two reports of rim fracture and “os acetabuli” in association with FAI. In the case we present, the pincer and cam resection were performed without complications; the technique used was published previously. With this technique the head of the screw lays hidden by the reattached labrum. We removed partially the fractured rim fragment and the internal fixation of the remaining portion was achieved with a screw. In the event of a complete resection of the fragment, it would have ended with a LCE angle of 18° and a high probability of hip instability. We believe that this bilateral case helps establish the efficacy and reproducibility of the technique described by Larson.

    antecedentes: el cáncer de mama en el hombre es una enfermedad con baja incidencia, que se reduce aún más cuando es bilateral sincrónica. Existen pocas publicaciones en los últimos años. Objetivo: establecer pautas para el tratamiento de este cáncer, aunque sea infrecuente. Caso clínico: paciente masculino de 75 años de edad, con tumores en ambas mamas, que se le resecaron completamente con exéresis de ganglios palpables. El estudio histopatológico informó que se trataba de un carcinoma ductal infiltrante no especificado. Se indicó tratamiento adyuvante con tamoxifeno y radioterapia; en la actualidad está libre de enfermedad. Conclusiones: el carcinoma mamario bilateral sincrónico en el varón es una enfermedad poco frecuente. Su tratamiento principal es la cirugía, de ahí la importancia del diagnóstico temprano. En la mayoría de los casos se requiere quimioterapia y radioterapia adyuvante porque suelen diagnosticarse en un estadio avanzado.

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

    Background. Despite advances in surgical repair of hiatus hernias, there remains a high radiological recurrence rate. We performed a novel technique incorporating bilateral oesophageal fixation and evaluated outcomes, principally symptom improvement and hernia recurrence. Methods. A retrospective study was performed on a prospective database of patients undergoing hiatus hernia repair with bilateral oesophageal fixation. Retrospective and prospective quality of life (QOL), PPI usage, and patient satisfaction data were obtained. Hernia recurrence was assessed by either barium swallow or gastroscopy. Results. 87 patients were identified in the database with a minimum of 3 months followup. There were significant improvements in QOL scores including GERD HRQL (29.13 to 4.38, P < 0.01), Visick (3 to 1), and RSI (17.45 to 5, P < 0.01). PPI usage decreased from a median of daily to none, and there was high patient satisfaction (94%). 57 patients were assessed for recurrence with either gastroscopy or barium swallow, and one patient had evidence of recurrence on barium swallow at 45 months postoperatively. There was an 8% complication rate and no mortality or oesophageal perforation. Conclusions. This study demonstrates that our technique is both safe and effective in symptom control, and our recurrence investigations demonstrate at least short term durability. PMID:26065030

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

    The paper presents the results of gait parameters as a function of unilateral weight. The object of the research was a woman walking on a stationary surface and carrying in his hand weights from 0 to 15 kg. Her movement was recorded by 6 cameras recording the location of 34 markers placed at appropriate points in the body. 3D reconstruction was performed for each of the reflecting markers. Tested signals were changes in the value the joint angles of ankle, knee and hip. On the basis of about 6 cycles of movement of each load, a model for the average gait cycle was developed. The result of the experiments are graphs of changes the joint angles as a function of time, bilateral cyclograms, synchronized bilateral cyclograms and regression lines. The conclusion of the study is to determine how one-sided load affects gait asymmetry. Simple and easy to interpret method of presentation of results were also shown. Studies were conducted using VICON system.

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

  20. The bilateral advantage for famous faces: interhemispheric communication or competition?

    Baird, Lyndsay M; Burton, A Mike

    2008-04-01

    The bilateral advantage for the perception of famous faces was investigated using a redundant target procedure. In experiment 1 we compared simultaneous presentation of stimuli (a) bilaterally and (b) one above the other in the central field. Results showed a redundancy advantage, but only when faces were presented bilaterally. This result lends support to the notion of interhemispheric communication using cross-hemisphere representations. Experiment 2 examined the nature of such communication by comparing bilateral presentation of identical face images, with bilateral presentation of different images of the same person. When asked to make a familiar/unfamiliar face judgement, participants showed evidence for a redundancy advantage under both bilateral conditions. This suggests that the nature of the information shared in interhemispheric communication is abstract, rather than being tied to superficial stimulus properties.

    Full Text Available Durante los años 1935 a 1937 se produjo una importante sequía que afectó duramente a las regiones áridas y semiáridas del noroeste argentino, así como de México y Estados Unidos. En esta nota se estudia la repercusión de ese acontecimiento ambiental sobre la economía y la sociedad de Santiago del Estero, que marca un antes y un después en su historia agraria. Hasta ese año se consolidó el modelo agroforestal surgido entre 1880-1900, que combinaba el obraje, la finca y la economía campesina. La gran sequía hizo fracasar dos cosechas seguidas, y disminuyó el stock ganadero vacuno y caprino en un 80%. Esto tuvo consecuencias catastróficas en una sociedad rural, cuya dieta dependía en gran medida de su propia producción, desatando la hambruna más notable en la historia contemporánea de esta provincia. Entre las numerosas consecuencias de esta sequía, estudiamos sus efectos en la población, la economía y las políticas públicas. Las iniciativas del Estado fueron dispersas y tardías, y no pudieron contener los problemas de miles de familias que enfrentaron el hambre y el desamparo social. Este drama regional adquirió dimensión nacional a través de la prensa oral y escrita, que en los últimos meses de 1937 promovió una campaña solidaria en gran escala. El éxodo inauguró un sendero migratorio hacia las zonas fabriles de Berisso, Ensenada y el Gran Buenos Aires. La sequía también estimuló la construcción de los diques Los Quiroga (1949 y la presa de embalse de Río Hondo (1968. La literatura también recogió este tema como símbolo del drama campesino en el imaginario colectivo.During the years 1935 to 1937 there was a significant drought that hit the arid and semiarid regions of northwestern argentina, as well as from Mexico and the United States.

    Full Text Available La política ambiental en México se implementó como un mecanismo para frenar el deterioro en áreas naturales como la Reserva de la Biosfera de la Mariposa Monarca, sin embargo, se cuestiona su eficacia debido al continuo deterioro, la pérdida de bosques, la mortandad de la mariposa, y la disminución de mantos freáticos; todo esto acentuado por el turismo masivo. Esto es consecuencia de las dificultades de implementación de la política ambiental y de los actores que participan en ella. El análisis se realizó bajo el enfoque de Redes de Política Pública. La principal conclusión es que existe una limitada coordinación interinstitucional y esto dificulta la comunicación y acuerdo entre actores.

    Full Text Available This paper presents a novel bilateral filtering using weighed fcm algorithm based on Gaussian kernel unction for image manipulations such as segmentation and denoising . Our proposed bilateral filteringconsists of the standard bilateral filter and the original Euclidean distance is replaced by a kernel – induced distance in the algorithm. We have applied the proposed filtering for image denoising with both the impulse and Gaussian random noise, which achieves better results than the bilateral filtering based denoising approaches, the Perona-Maliks anisotropic diffusion filter, the fuzzy vector median filter and the Non-Local Means filter.

    Full Text Available Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessels. Eye involvement may be in the form of retinal detachment which is a potentially dangerous manifestation for its sight threatening nature .We report a case where a 17 year old male developed sudden blindness due to spontaneous bilateral retinal detachment. Examination revealed features of Marfan syndrome and was stamped as a case of Marfan syndrome by Ghent criteria . The point to stress upon is that a young male developing spontaneous retinal detachment, a diagnosis of underlying Marfan syndrome should be kept in mind if appropriate clinical stigmata are present.

  1. Bilateral Trade Flows and Income Distribution Similarity

    2016-01-01

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980–2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories. PMID:27137462

    Full Text Available Tuberculosis is an important cause of uveitis in our country. India has been declared the country with the highest tuberculosis burden with 25 % of the cases . (1 This is especially true in Andhra Pradesh and Telangana which have a high percentage of affected patients. However , tuberculous uveitis is usually a unilateral presen tation. We report a case of bilateral uveitis of tuberculous origin in a 55 year old woman. She presented with different tuberculous manifestations in the two eyes. While the RE showed non granulomatous uveitis with sclerosing keratitis , the LE showed gran ulomatous uveitis with mutton fat keratic precipitates. Systemic examination revealed an enlarged lymph node which was positive for tuberculosis on biopsy. She was hence diagnosed as extra pulmonary tuberculosis and was treated with ATT regimen. In this pa tient , uveitis was the initial manifestation and resulted in a systemic diagnosis.

    Bilateral adrenal hemorrhage (BAH) is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency. PMID:27609733

It would be advantageous to produce a film with both surfaces microstructured, as this increases the film’s performance efficiency. The new technique introduced herein produces bilaterally microstructured film by combining an embossing method...... retain an imprint made on it. The preheated film at gel point is embossed between the rolls of a gravure lab coater, which corrugates the top surface of the film. The films are then heated, in order to cure completely. For the LSR systems used in this process, the optimum conditions for preheating...... are 110°C for 4–7 s, while for embossing the temperature is 110°C with 25 psi pressure between the rolls at a speed of 1.4 rpm. Scanning electron microscope (SEM) images confirm the formation of microstructures on both the surfaces of the film....

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980-2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories.

    This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs. PMID:27583120

    A 40-year-old male paddy field worker was referred for exertional shortness of breath and non-productive cough for 4 years. He had been treated for pulmonary tuberculosis twice. Chest radiograph showed extensive bilateral nodular opacities ("sandstorm-like") in the middle and lower lobe. Pulmonary function tests revealed a restrictive ventilatory defect. High resolution CT showed widespread nodular infiltration with "crazy paving" appearance and interrupted black pleura sign. This was confirmed as pulmonary alveolar microlithiasis (PAM) by trans-bronchial lung biopsy, which showed normal respiratory lining epithelium with dilated alveolar spaces containing many calcific bodies, some of which showed concentric calcification. The possibilities of silicosis (due to exposure to husk) and tuberculosis, both of which can mimic PAM clinically and radiologically, made this case a diagnostic challenge. PMID:21686505

  10. El lactato como posible factor del mecanismo de fatiga muscular.

    2009-10-01

    Full Text Available Se revisa el papel del lactato en la función muscular. Se destacan los siguientes conceptos: el lactato es un intermediario metabólico que aumenta durante el ejercicio de alta intensidad, como consecuencia de la elevada actividad glicolítica. En esas condiciones la formación de ATP se asocia con generación de iones lactato e H+ y se reduce el pH de la célula activa. Si hay fatiga, el aumento en los niveles de lactato se correlaciona con la magnitud en la caída de la fuerza y los niveles de lactato alcanzados a un determinado nivel de actividad dependen del tipo de la fibra muscular. La salida de lactato de la fibra ocurre principalmente por 3 mecanismos de los cuales el más importante es el cotransporte acoplado de lactato-H+, cuya actividad depende del tipo de fibra y del patrón de activación así como del pH y de la concentración del amortiguador (buffer externos. De los varios factores responsables de la fatiga muscular, la disminución de pH se ha señalado como uno de los más importantes. No obstante, a pesar de la relación entre fatiga muscular y disminución de pHi, ésta no parece ser suficiente para explicar el grado de reducción de la fuerza durante la fatiga. Recientemente se han realizado experimentos que muestran un efecto inhibidor del lactato sobre el canal de liberación de calcio del retículo sarcoplásmico, lo que sugiere fuertemente que el lactato per se, y no necesariamente el cambio de pHi asociado, puede jugar un papel importante en el mecanismo de la fatiga. Por otra parte, el lactato podría tener efecto benéfico en la recuperación de la fuerza tetánica y de la capacidad de mantener la fase de meseta durante el tétanos, que se reducen por efecto de la fatiga. Asimismo, el aumento de lactato podría jugar un papel protector de la fibra durante la fatiga, mediante la activación de los canales de K+ sensibles a ATP. El músculo produce y consume lactato y al aumentar sus niveles en la sangre, este ion lo

    Recent findings indicate that conscious attention is related to large-scale information integration of various brain regions, including both hemispheres, that enables integration of parallel distributed modalities of processed information. There is also evidence that the level of information transference related to integration or splitting among brain regions, and between hemispheres, establishes a certain level of efficiency of the information processing. The level of information transference also may have modulatory influences on attentional capacity that are closely linked to the emotional arousal and autonomic response related to a stimulus. These findings suggest a hypothesis that changes in conscious attention, specifically during meditation could be reflected in the autonomic activity as the left-right information transference calculated from bilateral electrodermal activity (EDA). With the aim to compare conscious attention during meditation with other attentional states (resting state, Stroop task, and memory task), we performed bilateral EDA measurement in 7 healthy persons during resting state, Stroop task, neurofeedback memory test, and meditation. The results indicate that the information transference (ie, transinformation) is able to distinguish those attentional states, and that the highest level of the transinformation has been found during attentional processing related to meditation, indicating higher level of connectivity between left and right sides. Calculations other than pointwise transinformation (PTI) performed on EDA records, such as mean skin conductance level or laterality index, were not able to distinguish attentional states. The results suggest that PTI may present an interesting method useful for the assessment of information flow, related to neural functioning, that in the case of meditation may reflect typical integrative changes in the autonomic nervous system related to brain functions and focused attentional processing.

    2007-12-01

    Full Text Available A fibrose cística, também conhecida como mucoviscidose, é um distúrbio monogenético que se apresenta como uma doença multissistêmica. A incidência é de aproximadamente 1:2500 nascidos vivos. O mecanismo fisiopatológico é uma mudança qualitativa em todas as secreções exócrinas do organismo. O aumento da viscosidade dessas secreções leva à estase e obstrução mecânica, prejudicando a função secretora dos órgãos-alvo. O nariz e seios paranasais são freqüentemente envolvidos devido ao clearence mucociliar anormal, responsável pelo desenvolvimento de rinossinusite crônica, polipose nasal e pseudomucocele sinusal. OBJETIVO: É apresentar um caso raro de pseudomucocele bilateral em uma criança portadora de fibrose cística. DESCRIÇÃO DO CASO: M.F.B.R., 2 anos, masculino, apresentava obstrução nasal crônica e infecções pulmonares recorrentes. O exame clínico detectava presença de secreção nasal abundante, com descarga posterior em orofaringe. A tomografia computadorizada dos seios paranasais mostrou imagem sugestiva de pseudomucocele, com velamento dos seios maxilares e etmóides. A dosagem de sódio e cloro no suor apresentou alterações significativas. Optamos por tratamento cirúrgico, após internação do paciente para controle das manifestações pulmonares exacerbadas. A criança evoluiu com melhora do quadro obstrutivo nasal. CONCLUSÕES: A pseudomucocele é uma entidade que começou a fazer partes da rotina de diagnóstico diferencial a partir do momento em que os exames tomográficos tornaram-se parte da semiologia das doenças sinusais. Os pacientes com psedomucocele têm apresentado um aumento importante da sobrevida graças aos tratamentos atuais.Cystic fibrosis, also known as mucoviscidosis, is a monogenetic disorder that is presented as a multisystemic disease.

    Full Text Available Relata-se o caso de um paciente com dispnéia intensa ao se deitar, em que foram excluídas doenças pulmonares, neuromusculares ou cardíacas, cuja investigação revelou paresia diafragmática bilateral. Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

    In this paper, we introduce a high efficient and practical disparity estimation using hierarchical bilateral filtering for real-time view synthesis. The proposed method is based on hierarchical stereo matching with hardware-efficient bilateral filtering. Hardware-efficient bilateral filtering is different from the exact bilateral filter. The purpose of the method is to design an edge-preserving filter that can be efficiently parallelized on hardware. The proposed hierarchical bilateral filtering based disparity estimation is essentially a coarse-to-fine use of stereo matching with bilateral filtering. It works as follows: firstly, the hierarchical image pyramid are constructed; the multi-scale algorithm then starts by applying a local stereo matching to the downsampled images at the coarsest level of the hierarchy. After the local stereo matching, the estimated disparity map is refined with the bilateral filtering. And then the refined disparity map will be adaptively upsampled to the next finer level. The upsampled disparity map used as a prior of the corresponding local stereo matching at the next level, and filtered and so on. The method we propose is essentially a combination of hierarchical stereo matching and hardware-efficient bilateral filtering. As a result, visual comparison using real-world stereoscopic video clips shows that the method gives better results than one of state-of-art methods in terms of robustness and computation time.

    Directory of Open Access Journals (Sweden)

    M. J. Aguilar Cordero

    2014-05-01

    Full Text Available El cortisol salival es una hormona esteoridea producida en el eje hipotálamo-pitutitario-adrenal que se segrega en la saliva, sobre todo cuando las personas se estresan. Un nivel elevado de cortisol en saliva puede ser producido por muchos factores diferentes, entre los que se encuentran algunas alteraciones, como la obesidad y otras afecciones psicológicas. Los artículos seleccionados para ser incluidos en esta revisión se tomaron de Google Scholar y Medline, y con un total de 57 artículos. La validez de los mismos viene dada por el grado de evidencias demostrado, por las recomendaciones allí recogidas y por la aplicabilidad a nuestro contexto. En esta revisión se han considerado los estudios que investigan el cortisol salival y el estrés en niños y adultos. También se han tenido en cuenta los que relacionan unos niveles altos de cortisol salival con otras alteraciones, como ansiedad, TDAH, fobia social o la carencia afectiva. Los estudios demuestran que el cortisol salival es un claro indicador de estrés, tanto en niños como en adultos. Las principales consecuencias de un alto nivel de esta hormona en la saliva son las siguientes: reducción de la función inmunológica, que afecta a la cicatrización y, como consecuencia, a un mayor tiempo de recuperación. También se relaciona con un déficit en el crecimiento físico de los niños, así como con un aumento de la presión arterial y de la frecuencia cardíaca, tanto en niños como en adultos.

    Bilateral obturator nerve injury during pelvic surgery is an infrequent cause of lower limb paraparesis. We report the case of a 45-year-old woman with a large uterine leiomyoma who underwent simple total hysterectomy and bilateral salpingectomy. At 24 h after the surgery, the patient noticed loss of muscle strength when adducting both legs. She had no problem with other movements and no sensory or sphincter abnormalities. Neurological examination confirmed that there was loss of strength only in the adductor muscles, with preserved sensory function and reflexes, suggesting bilateral obturator nerve involvement. Pelvic MRI showed a small postsurgical haematoma in the Douglas recess, but far from the obturator nerves. 2 weeks later, electromyography showed positive sharp waves and low motor unit recruitment in the adductor magnus muscles, confirming acute, bilateral obturator nerve neuropathy. The few cases of bilateral obturator neuropathy that have been reported were mostly related to abdominopelvic interventions. PMID:26689250

    2016-06-01

    Bilateral clavicle fractures are uncommonly reported in the literature with the incidence being less than 0.5% of all the clavicle fractures. Bilateral clavicle fractures are caused either by high-energy transfer of compression forces across both shoulder girdles or by a direct trauma to one clavicle followed by that to the other clavicle. These fractures could be missed due to their association with more severe chest injuries or a more symptomatically displaced fracture on one side or due to inadequate chest radiographs. We report three cases of traumatic bilateral clavicle fractures with three modes of injuries in different age groups. All the fractures were treated conservatively with good functional outcomes without any sequelae. Bilateral clavicle fractures should be actively sought by every trauma team with proper clinical examination and chest radiographs including both shoulder joints in high-energy trauma cases or with bilateral shoulder compression injuries.

    The aim of this article is to report the MRI features of bilateral parotid haemangiomas of infancy and highlight the diagnostic and prognostic value of MRI especially with regard to those lesions that may cause respiratory compromise. Retrospective review of MRI scans in six infants with bilateral parotid haemangiomas. The bilateral haemangiomas were symmetrical in all but one patient. On T1-weighted images the masses were isointense to muscle and on T2 they were hyperintense with numerous small vessels giving a septated appearance. There was vivid enhancement with gadolinium in all cases. In three patients, deep bilateral extensions were demonstrated involving the parapharyngeal spaces resulting in respiratory compromise which required tracheostomy. Bilateral parotid haemangiomas are rare, but when present may have deep extensions, which can result in respiratory compromise requiring tracheostomy. (orig.)

    Bilateral periventricular nodular heterotopia is a neuronal migration disorder characterized by gray matter cellular rests in the periventricular regions. Megalencephaly has not been reported in children with bilateral periventricular nodular heterotopia. No other disorder with a similar phenotype has been reported. Here we report the case of a 5-year-old Japanese boy with bilateral periventricular nodular heterotopia and megalencephaly. Relative macrocephaly was evident at birth, and bilateral periventricular nodular heterotopia and megalencephaly were noted on magnetic resonance imaging (MRI). However, no hydrocephalus or indication of cerebral cortical dysplasia was seen. A mild intellectual disability was present, but the patient had no history of seizures. Genetic analysis revealed no mutation on the capillary sequences for FLNA, and no pathogenic abnormalities were evident on array comparative genomic hybridization. This case could represent a new disease entity: bilateral periventricular nodular heterotopia with megalencephaly. PMID:23439715

    Full Text Available Background. The incidence of tubal ectopic gestation caused by schistosomiasis induced tubal pathology is undocumented in this environment, which may be due to rarity of this pathology. Bilateral tubal gestation is common in patients that have undergone in vitro fertilization. We report a hitherto undocumented case of spontaneous bilateral ectopic gestation following tubal schistosomiasis. Case Report. Mrs. OB was a 32-year-old G4P3+0 (3 alive woman who complained of abdominal pain and bleeding per vaginam of 4 and 2 days’ duration respectively following 8 weeks of amenorrhea. A clinical impression of ruptured ectopic gestation was confirmed by ultrasound scanning. She had bilateral salpingectomy with histology of specimens showing bilateral ectopic gestation with Schistosoma haematobium induced salpingitis (findings of Schistosoma haematobium ova noted on slide. Conclusion. Schistosoma induced salpingitis is a rare but possible cause of bilateral tubal gestation.

    Full Text Available El cuidado provisto por familiares o amigos a los adultos dependientes es un proceso social decisivo para el bienestar de la sociedad española. Este tipo de apoyo tiene intensas consecuencias sobre quienes cuidan. En este artículo se plantea que la valoración precisa del impacto de la dependencia en el entorno social requiere de análisis comprensivos y multidisciplinares, y se elabora una propuesta de clasificación de las consecuencias del cuidado familiar sobre el cuidador. En dicha propuesta estos efectos pueden ser positivos o negativos, y afectar a diferentes dimensiones vitales de los cuidadores: salud, economía o relaciones sociales.Care provided by relatives or friends to dependent people is a key process to promote wellbeing in Spanish society. This type of support has intense consequences over caregivers' lives. Comprehensive and multidisciplinary analyses are required to assess dependency effects over social network. In this paper we elaborate a classification of types of family care consequences over caregivers. We differentiate between positive or negative consequences, and between consequences affecting caregivers' health, economy and/or social relations.

  2. Comparative gait initiation kinematics between simulated unilateral and bilateral ankle hypomobility: Does bilateral constraint improve speed performance?

    Improvement of motor performance in unilateral upper limb motor disability has been shown when utilizing inter-limb coupling strategies during physical rehabilitation. This suggests that 'default' bilateral central motor commands are facilitated. Here, we tested whether this bilateral motor control principle may be generalized to the lower limbs during gait initiation, which involves alternate bilateral actions. Disability was simulated by strapping to produce ankle hypomobility. Healthy adult subjects initiated gait at a self-paced speed with no ankle constraint (control), or with the stance, swing or bilateral ankles strapped. The duration of the anticipatory postural adjustments lengthened and the center of mass instantaneous progression velocity at foot-off decreased when the ankle was strapped. During the step execution phase, progression velocity at foot-contact was higher when both ankles were strapped compared to unilateral strapping of the stance ankle. These findings suggest that bilateral central motor commands are favored during walking tasks. Indeed, unilateral constraint of the stance ankle should compel the central nervous system to adapt specific commands to the constraint and normal sides whereas the 'default' bilateral motor commands would be utilized when both ankles are strapped leading to better kinematics performance. Bilateral in-phase upper limb coordination and bilateral alternating lower limb locomotor movements may share similar control mechanisms. PMID:26197055

    Full Text Available Objetivo: Determinar la prevalencia, la naturaleza y las consecuencias de los abusos sexuales sufridos durante la infancia o la adolescencia. Métodos: 2.159 estudiantes de la Universidad de Granada respondieron voluntariamente y de forma anónima a un cuestionario sobre abuso sexual. Establecido el grupo de víctimas, se formó otro de comparación con estudiantes sin antecedentes de abusos. En una segunda sesión se evaluó la salud mental de ambos grupos. Resultados: 269 (12,5% estudiantes manifestaron haber sufrido abusos sexuales antes de los 18 años de edad. El 62,8% de los abusos consistió en tocamientos y la edad media de inicio fue a los 8,8 años. Los perpetradores, mayoritariamente varones y un 44% menores de edad, solían cometer los abusos en el hogar de la víctima o en el suyo, aprovechándose de las visitas o de su estrecha vinculación. Alrededor del 50% se sirvió del engaño o del juego. En cuanto a la salud mental de las víctimas, las universitarias con antecedentes de abusos sexuales tenían menor autoestima y asertividad, y puntuaciones más altas en actitud vital negativa, depresión y ansiedad, que las del grupo de comparación. Las víctimas varones, sin embargo, sólo diferían de los universitarios sin antecedentes de abusos en su mayor nivel de ansiedad. Conclusiones: Los resultados demuestran la gravedad del problema de los abusos sexuales a menores y sus consecuencias, así como las circunstancias en que se producen y el perfil de los agresores y de las víctimas; unos resultados relevantes para la planificación de programas de detección y prevención de los abusos.Objective: To analyze the prevalence, nature and consequences of sexual abuse during childhood or adolescence.

  5. El singular como diferencia divina

    Full Text Available Mucho se ha hablado sobre la posición de la diferencia como motor dialéctico de la existencia singular kierkegaardiana. El pecado, el otro o el Otro fisuran la subjetividad humana y la obligan a una identidad que guardará siempre la herida. El sujeto de la escisión es, en este sentido, el existente mismo, y tal debe ser el caso si la perspectiva se concentra en la individualidad. No obstante, y desde el punto de vista especulativo, creemos que los mismos principios utilizados por Kierkegaard para explicar el dinamismo de la existencia singular nos llevan más lejos, a saber, nos conducen al absoluto mismo como sujeto último de toda alteridad, respecto del cual el singular hace la diferencia.

    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

    2015-11-01

    Full Text Available : Mineralisation of all components of stylohyoid complex or chain, a 2nd branchial arch derivative is frequently reported. But bilateral occurrence of continuous bands of ossified tissue involving stylohyoid complex, are less commonly encountered. An adult skull specimen presented abnormally long osseous bands extending from base of skull in place of styloid process. On left side a band of 6.5cm long x1cm wide and 0.3cm in thickness, and on right side an irregularly rounded elongated structure of 7.5cm length were noticed. Lower end of the left process was fused to hyoid bone. Either abnormally long styloid process or this type of ossified stylohyoid complex may be a causative factor for severe pharyngeal pain, dysphagia, may be a cause for occasional swelling in submandibular region or may be associated with Eagle syndrome. Due to its close proximity to tonsillar bed, if elongated it may be felt during tonsillectomy in tonsillar fossa. In this backdrop reports of this type may be of interest to clinicians.

    2013-01-01

    Full Text Available We herein report a case of synchronous bilateral solid papillary carcinoma of the breast. A 73-year-old female had a mass that was detected in the right breast on mammography. An ultrasound examination revealed one intracystic tumor in the right breast and two tumors in the left breast. A fine-needle aspiration biopsy of these three tumors was performed, which revealed a diagnosis of malignancy. A magnetic resonance imaging examination of the breasts showed diffuse small nodules surrounding these tumors bilaterally. Bilateral partial mastectomy and a sentinel lymph node biopsy were performed. Lymph node metastasis was detected in the right axilla, and additional lymph node dissection was performed. The pathological diagnosis was synchronous bilateral breast cancer, invasive ductal carcinoma NOS of the right breast, mucinous carcinomas of the left breast, and bilateral SPCs. A wide range of surgical margins were positive for SPCs, and additional bilateral total mastectomy was then performed. To the best of our knowledge, little is known about synchronous bilateral SPCs. Our case indicates that some SPCs can be widely scattered and make up a variety of invasive carcinomas. It is difficult to make a correct preoperative evaluation in such cases.

    2012-07-01

    Full Text Available Maisonneuve fractures result from a disruption of the medial ankle structures and a proximal fibular fracture. Patient complaints can be misleading and there is a significant rate of delayed diagnosed injuries. We present a case of bilateral Maisonneuve fractures after a fall due to a syncopal collapse. A precise clinical examination led to this rare diagnosis. The injuries were treated with syndesmotic screw fixation, removal of hardware followed after 6 weeks. The patient was asymptomatic at threemonths follow up. Patients with bilateral injuries undergoing standard surgical treatment can gain full recovery, but high suspicion in clinical examination is needed to detect this uncommon bilateral injury.

    Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: In order to achieve its long-term emission reduction target following the Fukushima incident, Japan would rely more heavily on international offsetting activities. Concurrent to vigorous proposals to reform the CDM, Japan is also promoting an offset crediting scheme through bilateral agreements with developing countries as a post-2012 market mechanism. Despite potential benefits, issues relating to the accounting rules, environmental integrity and implications to carbon markets warrant further consideration prior to international recognition

    2010-01-01

    Full Text Available El objetivo general de esta investigación es analizar si las respuestas comportamentales de los consumidores ante un servicio insatisfactorio difieren en función de las emociones que éstos experimentan. En concreto, se analiza la influencia del enfado y del arrepentimiento sobre el comportamiento de queja del consumidor, su comportamiento post-compra y la importancia que concede a posibles estrategias de restitución del servicio que puede desarrollar la empresa. Apoyados en los resultados de un estudio empírico en hoteles y restaurantes, se puede concluir que tanto sujetos enfadados como arrepentidos no regresan a la empresa, hablan negativamente de la misma y valoran de forma similar el desarrollo de diversas estrategias de recuperación del servicio. Sin embargo, los sujetos enfadados tienden a quejarse más, mientras que los consumidores arrepentidos son más comprensivos con los empleados de la organización.

    2010-01-01

    La historia de la migración México-Estados Unidos se caracteriza por una serie de periodos durante los cuales los patrones migratorios se transforman y evolucionan como respuesta a los cambios en la política migratoria de Estados Unidos. En la década de 1990 se dio uno de estos cambios, lo que provocó el paso de la ‘era de la contradicción’ a la ‘era de la marginalización’. Actualmente, un gran número de migrantes indocumentados permanecen al margen de la ley, precisamente en un periodo en el que las penas se han incrementado y la persecución ha alcanzado niveles récord. De manera cada vez más notoria, los migrantes indocumentados, por la represión interna y fronteriza, quedan obligados a romper los lazos que los vinculaban con sus lugares de destino, pero al mismo tiempo se sienten cada vez más extraños en una tierra donde la aplicación de políticas antiinmigrantes es cosa de todos los días, lo que los sitúa en una posición de marginalización y gran vulnerabilidad.

    Full Text Available El debate sobre la eutanasia en España está mediatizado por un caso tipo, similar al que se utilizó en Estados Unidos con Roe versus Wade. Este es el caso Sampedro. Por razón del sistema de fuentes español, preferentemente continental, este caso buscó más la influencia política que la resolución jurídica. En su trayecto judicial, las resoluciones, tanto en instancias nacionales como internacionales, fueron contrarias a las pretensiones de Sampedro pero, en general, no abordaron las razones sustantivas por las que no debería aceptarse la retirada del Estado en caso de homicidio compasivo. El debate tuvo efectos en España en la Comisión Senatorial sobre la eutanasia, que se manifestó globalmente en contra, y en la legislación sobre voluntades anticipadas, también opuesta a la eutanasia. Por la presión mediática, especialmente en el cine, el tema ha seguido en discusión, siendo la posición del actual Gobierno ambigua respecto a la posibilidad de legalización

Investigaciones realizadas en Cuba reflejan que un elemento importante en esta dirección lo constituye la baja percepción de riesgo en la sociedad cubana en la prevención de desastres naturales, fundamentalmente en la etapa de la adolescencia. La presente investigación, tuvo lugar en tres secundarias básicas del territorio espirituano, seleccionando un grupo de 30 estudiantes en cada una para buscar información. Como resultado se sistematizaron los referentes teóricos-metodológicos que sustentan la percepción de riesgos como componente de la Educación Ambiental para el Desarrollo Sostenible. Además, derivado de un estudio preliminar, se presentan procedimientos que permiten contribuir a la educación de la percepción de riesgos en los adolescentes, tomando como referencia la situación ambiental comunitaria y el modelo actual de escuela Secundaria Básica.

  9. Los asilados de las Embajadas de Europa Occidental en Chile tras el golpe militar y sus consecuencias diplomáticas: El caso de Suecia

    Full Text Available Abstract: The asylum seekers of the embassies of western Europe in Chile after the military coup and their  diplomatic consequences: The case of SwedenGiven te expectations that western governments  had in the reforms being implemented by the  Unidad Popular, the September 1973 coup d’état  in Chile caused a great international outcry. The  violence and repression that accompanied the  military coup produced a worldwide repudiation  of the military junta. Sweden stood out most consistently among the countries that declared  their opposition to Chile during the period of the  dictatorship by continuously denouncing the  violations to human rights. In this context, Sweden’s Ambassador to Chile, Harald Edelstam, played a very important role in saving the lives of  hundreds of Chilean citizens and foreign nationals  who sought refuge from the regime’s bloody  repression. Making use of the privileges he enjoyed as a diplomat, Edelstam confronted the  military authorities to release people wrongfully  sentenced to the death penalty. As a result, he was  declared persona non grata and forced to leave  Chile. This was the beginning of a long and controversial diplomatic relationship that lasted until  the return of democracy in Chile in 1990. This  article is a first attempt at understanding how  human rights violations affected bilateral relations  between Chile and Sweden with respect to the  diplomatic efforts of Ambassador Harald Edelstam. El golpe de Estado en Chile en septiembre de  1973 causó una gran conmoción internacional  debido a las esperanzas que tenían los gobiernos  occidentales en las reformas que estaba implementando la Unidad Popular. La violencia y represión que acompañaron al golpe militar redundaron en el repudio mundial de la Junta Militar.  Entre los países que se destacaron más firmemente en su oposición a Chile durante la dictadura se  encuentra Suecia, que denunció permanentemente

    The number of medical examinations and procedures that use ionizing radiation have continuously increased in recently years. More than 90% of human-generated exposures to ionizing radiation are from medical uses and the collective dose due to patient exposures is 200 times greater than the occupational dose of exposed workers. At the same time, the emergence of new technologies, the increased use of Computerized Tomography (CT)-even for pediatric patients- the development of digital radiography, interventional radiology and the new technologies in nuclear medicine with the use of hybrid PET/CT and SPECT/CT equipment have all contributed as well to an increase in the doses received by patients. This poses a challenge to the regulatory authorities in the field of radiological protection, the goal of which is to makes sure that the risks to patients are as low as possible compared to the benefits yielded by the use of ionizing radiation for medical purposes, in accordance with ALARA criteria.

O cão morreu por peritonite séptica aguda, decorrente de ulceração e perfuração intestinal por corpo estranho linear. O neoplasma foi achado incidentalmente durante a necropsia. Macroscopicamente, as adrenais estavam redondas e com volume e aumentados. Ao corte elas eram friáveis, vermelho-amarronzadas, intercaladas por áreas branco-amareladas levemente proeminentes. Histologicamente, extensas áreas do parênquima continham adipócitos bem diferenciados, células hematopoéticas e macrófagos com hemossiderina, achados característicos de mielolipoma adrenal.A case of bilateral adrenal myelolipoma in a 13-year-old female Poodle is reported. Acute septic peritonitis due to intestinal ulceration and perforation caused by a linear foreign body was the cause of death. The adrenal neoplasm was an incidental necropsy finding. The adrenal glands were grossly rounded, enlarged and friable, and had red-brownish parenchyma interwoven by slightly prominent white-yellowish foci. Histologically, the findings of differentiated adipocytes in large areas of the parenchyma, in association to hematopoietic cells and macrophages with hemosiderin were consistent with the diagnosis of adrenal myelolipoma.

    2012-01-01

    Full Text Available Bilateral sixth nerve paresis following closed head injury, though rare, is a known entity. However, delayed-onset post-traumatic bilateral abducens paresis is extremely rare. We present two cases. The first patient had onset of bilateral abducens paresis 2 weeks after closed head injury and the second patient after 3 days. The cause in the former was detected to be chronic subdural hematoma and in the latter is speculated to be edema/ischemia due to injury to soft tissue structures housing these nerves. The delayed onset of bilateral abducens paresis following head injury may vary according to the cause. There may be another mechanism of injury apart from direct trauma. Though rare, it needs to be evaluated and may have a treatable cause like elevated intracranial pressure.

  15. Bilateral Teleoperation in Cartesian Space with Time-Varying Delay

    Directory of Open Access Journals (Sweden)

    Zhang Chen

    2012-10-01

    Full Text Available The bilateral control of a teleoperator in Cartesian space with time‐varying delay is studied in this paper. Compared with the traditional joint‐space teleoperation mode, bilateral control in Cartesian space has advantages when dealing with the kinematically dissimilar (KDS teleoperation systems. A Cartesian space‐based PD‐like bilateral controller with dissipation factors is designed. Considering the fact that attitude errors derived by rotation matrix cannot be directly used for PD control, a quaternion‐based approach is adopted to calculate the attitude errors in Cartesian space. In order to overcome the instability brought about by communication delay, local damping components are employed at both ends of the teleoperator system. The variation of time delay may generate extra energy and influence the stability of the system, thus dissipation factors are introduced into the controller. The stability of the proposed bilateral controller is proved and the simulations show the effectiveness of the approach.

    Limbal stem cell deficiency (LSCD) is now established as a distinct entity with a spectrum of clinical manifestations. Bilateral LSCD presents a unique set of challenges to the clinician dealing with ocular surface disease, due to the underlying causes, clinical presentation, and adnexal status, as well as lack of a source of autologous limbal stem cells. Various surgical modalities have been described to achieve visual rehabilitation in patients with bilateral LSCD. These can primarily be divided into cell-based therapies and implantation of keratoprostheses. In this review, the surgical options for management of bilateral LSCD, including autologous and allogeneic cell-based therapies and different types of keratoprostheses are described and classified. The indications, prerequisites, technique, results and complications of each modality are discussed. Based on the status of the ocular surface, an algorithm for choosing appropriate surgical management for vision restoration in bilateral LSCD has been proposed. PMID:27151421

    After China and Australia established diplomatic ties in 1972, bilateral relations developed rapidly. People-to-people links, politicalexchanges and trade and economic cooperation played an increasingly larger part in the foreign policies of the two countries. In the post global financial crisis era, bilateral relations have remained positive and played an imPortant role in ensuring the stability and prosperity of the Pacific region. There have been several unavoidable misunderstandings and even disagreements between the two countries, which has influenced mutual trust and policies. This article will aim to analyze the history and current situation of the Sino-Australian relationship in an objective and comprehensive way; to look ahead to future bilateral relations, and make policy recommendations for the further development of bilateral ties to increase mutual understanding and promote a more positive future for Sino-Australian relations.

    2014-01-01

    Full Text Available La información biométrica que se extrae de las huellas dactilares tiende a ser diferente en cada adquisición, dada la incertidumbre existente en las mediciones y la presencia de ruido en las muestras, lo cual puede ocasionar que las palabras código generadas dentro de un extractor difuso posean un número de errores tal que rebase la capacidad de corrección de la codificación. Como consecuencia se tiene que lo anterior puede ocasionar que las huellas dactilares de una misma persona sean catalogadas como no coincidentes en su verificación o bien, que huellas de individuos diferentes parezcan demasiado similares. Para mitigar los efectos antes mencionados y sobrepasar las dificultades del pre-alineamiento de huellas dactilares, se propuso el uso de triángulos de Delaunay, lo cual permite proveer de estabilidad estructural local a la representación espacial de la información biométrica. En esa propuesta, las minucias de la huella son utilizadas como vértices de las triangulaciones y la red formada por éstas es tolerante a distorsiones, rotaciones y traslaciones. Sin embargo, en dicha propuesta se considera a la dispersión de minucias de huellas dactilares como no degenerativa y por tanto no se mencionan los umbrales o criterios necesarios para la formación de dichas triangulaciones, lo cual repercute en el desempeño de los extractores difusos. Con base en ello, este artículo presenta los resultados obtenidos al probar la formación de triangulaciones de Delaunay en imágenes de huella dactilar, en donde se aplican umbrales y criterios geométricos para luego contabilizar los triángulos coincidentes entre las estructuras formadas y definir los umbrales que maximicen dichas coincidencias.

    Full Text Available A punição de terroristas, em larga medida preliminar, ou os severos interrogatórios, não se adequam a um perfeito Estado de direito. Pertencem ao direito de exceção. Um Estado de direito que tudo abarque não poderia travar esta guerra, pois ele deveria tratar seus inimigos como pessoas e, conseqüentemente, não poderia tratá-las como fonte de perigo. Em Estados de direito que operam na prática de modo ótimo procede-se de outra maneira, e isso lhes dá a chance de não se quebrarem durante o ataque a seus inimigos.The preemptive punishment of terrorists and the use of harsh interrogation techniques are not within the classical standards of the Rule of Law. They belong rather to a state of exception. A State committed to all the usually accepted requirements of the Rule of Law would not be allowed to carry such a war, because it would have the duty to treat its enemies as persons. Therefore, it would not be authorized to treat them as a source of danger. Nevertheless, these classical standards have been challenged in the last two decades by major institutional changes that are now being discussed both in theoretical as in practical levels.

    Full Text Available Introduction: Bilateral shoulder dislocation are most commonly posterior type. These are most commonly due to seizure disorder and electrocution. Anterior shoulder dislocations occurring bilaterally without any predisposing factors are very rare. These types of injuries are due to trauma with a unique mechanism of injury. To best of our knowledge there are only few cases of similar kind are reported in literature. We hereby report a interesting case of posttraumatic, bilateral anterior dislocation of shoulder without associated fracture in a 45 old women without any predisposing pathoanatomy.Case Report: A 45-year-old women presented to casualty with sudden onset of pain and restriction of movement in both shoulders fallowing trauma. Immediately post trauma she had severe pain and restriction of both shoulders. On examination arms were abducted and externally rotated. Bilateral shoulder movements were painful and restricted . There was loss of round contour of shoulder with increased vertical diameter of axilla anteriorly. Radiological examination revealed bilateral anterior dislocation of the shoulders without any associated fractures. Closed reduction done by Milch technique after intraraticular lignocaine injection. MRI of bilateral shoulder showed no pathological lesion. Both shoulders were immobilized with a shoulder immobilizer for three weeks.Conclusion: Most of the bilateral shoulder dislocations are posterior type seen in seizure disorders. Bilateral traumatic anterior shoulder dislocations are rare and are seen as a result of unique mechanism of injury. In our case patient had a fall on her elbows causing forced extension. If diagnosed and treated promptly completely normal function of the shoulders can be restored.

    Various studies have demonstrated enhanced visual processing when information is presented across both visual hemifields rather than in a single hemifield (the bilateral advantage). For example, reported that observers were able to track twice as many moving visual stimuli when the tracked items were presented bilaterally rather than unilaterally, suggesting that independent resources enable tracking in the two visual fields.

    Bilateral Cochlear implants (CIs) improved speech intelligibility, speech perception in background noise, and sound localization in quiet and noisy situations. However, it is unclear whether these advantages essentially result in binaural integration of acoustic stimuli from each ear. In this study, we investigated the effectiveness of binaural integration by bilateral CIs placement using binaural hearing tests and subjective auditory perceptual assessment. A 61-year-old bilateral CIs subject underwent the following four tests:the Japanese Hearing in Noise Test (HINT-J), the dichotic listening test (DLT), the Rapidly Alternating Speech Perception (RASP) test, and subjective auditory perceptual assessment. The HINT-J score was significantly higher for bilateral CIs than for a unilateral CI. However, DLT and the RASP test revealed contradictory results. Subjective auditory perceptual assessment revealed active and bright impressions for bilateral hearing, which were also noisy and strong compared with those for unilateral hearing. The results of this study revealed that bilateral CIs improved speech perception in background noise and an improved auditory impression, although the bilateral integration abilities were not improved. This was probably because the patient was required to combine information from the two ears into a single perception in DLT and the RASP test. More longitudinal data should be collected and analyzed in future studies to evaluate the long-term effects of bilateral CIs.

    Benefits of bilateral practice both for the non-dominant and for the dominant body side have been shown in several studies. Thereby, most of the studies included movement tasks of the upper extremity or investigated sports games in which the ability of acting bilaterally is an essential basis for success and, thus, a bilateral practice is reasonable anyway. Individual unilaterally performed sports including movement tasks of the lower extremity are rarely investigated. Therefore, the aim of our study was to test if contralateral transfer due to bilateral practice can be found in an unilaterally performed sport including the lower extremity. We trained and tested 61 adolescent athletes in long jump to compare the jumping performance of the dominant leg after a 12-week practice period between two groups: a bilateral practice group that practiced specific long jump exercises with both the dominant and non-dominant leg and an unilateral practice group that practiced specific long jump exercises only with the dominant leg. Results showed a superior effect of bilateral practice compared to unilateral practice regarding the jumping performance of the dominant leg. The performance increase at post-test and retention-test for the dominant limb was significantly higher for the bilateral practice group (pre-to-post: 5.2%, pre-to-retention: 7.4%) compared to the unilateral practice group (pre-to-post: 3.4%, pre-to-retention: 4.5%). Thus, bilateral practice should be established in the early practice programmes of track and field athletes to improve the performance of the dominant take-off leg. PMID:26864045

    Full Text Available Introduction: Anterior dislocation of shoulder is commonest dislocation one encounters in day to day Orthopaedic practice. But bilateral shoulder dislocations are relatively uncommon frequently posterior and secondary to violent muscle contraction. Simultaneous bilateral anterior dislocations of shoulder following trauma is rare occurrence. Case Report: 35 year old male presented to emergency department with history fall by tripping on a stone (fall on outstretched hand. He complained of pain and difficulty in moving both the shoulders. On clinical examination, patient’s both upper limbs were abducted and externally rotated. Bilaterally shoulder contour was lost with flattening. Other classical signs of shoulder dislocation viz, Bryants test, Callway sign, Hamilton’s ruler test were positive. Diagnosis was confirmed on X rays. Both shoulders were reduced in emergency operation theater under general anaesthesia by Kocher’s method and were immobilised in sling. Conclusion: Though bilateral shoulder dislocations are commonly posterior, usually either secondary to convulsions or electric shock, anterior dislocation has to be kept in mind , especially in post traumatic injuries. This bilateral dislocation also presents with practical problems immobilization and day to day care of patients. Keywords: Simultaneous, bilateral, shoulder dislocation, traumatic.

    Full Text Available Introduction Sense of smell is susceptible to various changes, both in physiological and in numerous pathological conditions. Of quantitative disorders of smell, hyposmia and anosmia are quite common, whereas of qualitative disorders parosmia is most frequent. The aim of this paper was to examine impact of bilateral nasal polyposis on olfactory function. Material and methods The research was carried out at the Nose, Ear and Throat Clinic in Novi Sad. It included 80 examinees, 40 (20 male, 20 female with bilateral nasal polyposis, while 40 examinees belonged to the control group (20 male, 20 female without symptoms of nasal polyposes. Fortunato-Niccolini olfactometer was used for this examination. Results and discussion In patients with bilateral nasal polyposis the average perception threshold values for examined odors were 15.50 ccm of odorous air, while in the control group they were 10,20 ccm of odorous air. The average identification threshold values for examined odors in patients with bilateral nasal polyposis were 18.80 ccm of odorous air, while in the control group they were 13.55 ccm of scented air. T-test showed that values of both tresholds were statistically significantly higher (p< 0,01 in patients with bilateral nasal polyposis in relation to the control group. Conclusion Olfactory deficit in patients with bilateral nasal polyposis is explained by difficult or impossible passage of odors into the olfactory region.

    It is generally thought that simultaneous bilateral chest surgery carries a high morbidity. We reviewed the results of simultaneous (under one anesthesia) vs staged bilateral video-assisted thoracoscopic surgery (VATS) from a single institution over a 35-month period. From September 1992 to July 1995, we performed simultaneous bilateral VATS on 37 patients (31 males, six females, age ranging from 15 to 55 years) with spontaneous pneumothorax (20) for bleb resections and pleurodesis; thoracodorsal sympathectomy (12) for palmar hyperhidrosis and vasospastic disease; and metastatic sarcomas (five) for wedge lung resections. During the same period, nine patients with metachronous bilateral spontaneous pneumothorax had staged procedures, as did two with digital ischemic ulcers for sympathectomy and three with metastatic pulmonary osteosarcomas for resection. Mean postoperative hospital stays in days for the simultaneous groups were 3.3 for spontaneous pneumothorax, 2.1 for sympathectomy, and 1.5 for wedge resection, compared to 2.9, 2.5, and 2.2 for the staged groups, respectively (p > 0.05 by Mann-Whitney U tests). Likewise, pain assessment by visual analogue scale as well as analgesic requirement showed no significant difference between the simultaneous and the staged groups. We conclude that simultaneous VATS is not associated with increased morbidity or prolonged hospital stay compared to the staged counterparts and provides an attractive alternative to the median sternotomy, bilateral posterolateral thoracotomy, or transternal (clam-shell) thoracotomy for selected cases of simultaneous bilateral lung surgery.

    Full Text Available Purpose: The purpose of this study was to document clinical findings and management of a patient with bilateral globe luxation and optic nerve transection. Materials and Methods: A 25-year-old female patient was admitted to the emergency department with bilateral traumatic globe luxation following a motor vehicle accident. Results: Visual acuity testing showed no light perception. The right pupil was dilated and bilaterally did not react to light. The globes were bilaterally intact. A computed tomography scan revealed Le Fort type II fractures, bilateral optic nerve transection and disruption of all extraocular muscles. The globes of the patient were bilaterally reduced into the orbit. However, the patient developed phthisis bulbi in the right eye at month 3. Conclusion: Globe luxation presents a dramatic clinical picture, and may lead to the development of severe complications due to the concomitance of complete optic nerve dissection and multiple traumas. Even if the luxated globe is repositioned into the orbit, there is still an increased risk of the development of phthisis due to ischemia.

    Full Text Available In a fascinating and enigmatic passage of the Metaphysik der Sitten, Kant produced a definitive methodological change in the justification of the acquisition of what is «mine and thine exterior». This change was introduced by means of the rational and not empirically verifiable hypothesis of common original acquisition of land: «All men are originally and before any juridical act of will in rightful possession of the soil; that is, they have a right to be (da Sein wherever nature or chance has placed them without their will». In this way, the passionate supporter of the acquired -not innate- character of property rights makes room for the only natural right proceeding from the exercise of (external freedom: the right of mankind to take possession of a place on the Earth's limited spherical surface. A historical and political interpretation of these passages makes possible to assess the revolutionary consequences of an apparently «minor» methodological change.

    En un pasaje a la vez críptico y fascinante de la Metaphysik der Sitten, Kant generó un cambio metodológico definitivo para justificar la adquisición de «lo mío y lo tuyo exterior», mediante la hipótesis racional y no empíricamente comprobable de la apropiación originaria común del suelo: «Todos los hombres están originariamente (con anterioridad a todo acto jurídico del arbitrio en posesión legítima del suelo, es decir, tienen derecho a existir (da Sein ahí donde (al margen de su voluntad los han situado la naturaleza o el azar». Es así como el apasionado defensor del carácter adquirido -no innato- del derecho de propiedad deja espacio para un único derecho natural emanado del ejercicio de la libertad (externa: el derecho de todo el género humano a tomar posesión de un lugar en la superficie esférica y no infinita de la tierra.

    Emphysematous pyelonephritis (EPN) is a serious infectious disease that occurs more frequently in diabetic patients. Radiological studies are indispensable for distinguishing between the two types since each is associated with a markedly different prognosis. We present a case of bilateral EPN diagnosed as type I on the basis of computed tomography findings, differentiating it from type II EPN, taking into account the prognostic value of this distinction. Type I EPN is characterized by the destruction of the renal parenchyma, a mottled or linear gas pattern and the absence of renal and perirenal fluid collection. Type II EPN is characterized by a loculated or bubbly gas pattern, the existence of fluid collection and less marked renal destruction. Type I is more aggressive and is associated with high rate of mortality. (Author) 7 refs.

    Background This retrospective clinical investigation aimed to evaluate the short-term effectiveness and safety of SBCAS for symptomatic bilateral high-grade CS. Material/Methods From 2009 to 2014, 145 patients were recruited. Among them, 70 underwent SBCAS, and other 75 patients underwent SAMM and served as controls. The immediate postprocedural complications and postprocedural neurological evaluation, as well as restenosis at 6-month and 1-year follow-ups in the SBCAS group are reported. Additionally, baseline risk factors for ischemic stroke, adverse effects of drugs, and outcomes at 30-day, 6-month, and 1-year follow-ups were compared between the 2 groups. Results Our data did not reveal significant differences between the 2 groups in baseline risk factors for ischemic stroke. In the SBCAS group, both HPS (5.7%) and HD (40%) occurred, but they were not very severe, and no patients had postprocedural neurological deficit. Moreover, restenosis only occurred in 3 patients at 3 stent placement sites (4.3%) at 1-year follow-up. Adverse effects of drugs did not occur in SBCAS group, but adverse effects of Bayer aspirin and Lipitor occurred in 4 patients (5.4%) and 18 patients (24.3%), respectively, at 6-month follow-up in the control group. Furthermore, there were significant differences in outcomes between the 2 groups at 30-day, 6-month, and 1-year follow-ups, in that NIHSS, CS ratio, and incidence of endpoint events, as well as 1-year cumulative probability of endpoint events, were all lower in the SBCAS group than in the control group (p<0.05). Conclusions Compared to SAMM, we found that SBCAS was more effective and safer for symptomatic bilateral high-grade CS. PMID:27542158

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002-2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2-8) days. Median survival was 26 months (95% confidence interval (CI), 19-33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2-23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    Background Bilateral adrenal masses may have aetiologies like hyperplasia and infiltrative lesions, besides tumours. Hyperplastic and infiltrative lesions may have coexisting hypocortisolism. Bilateral tumours are likely to have hereditary/syndromic associations. The data on clinical profile of bilateral adrenal masses are limited. Aims To analyse clinical, biochemical and radiological features, and management outcomes in patients with bilateral adrenal masses. Methods Retrospective analysis of 70 patients with bilateral adrenal masses presenting to a single tertiary care endocrine centre from western India (2002–2015). Results The most common aetiology was pheochromocytoma (40%), followed by tuberculosis (27.1%), primary adrenal lymphoma (PAL) (10%), metastases (5.7%), non-functioning adenomas (4.3%), primary bilateral macronodular adrenal hyperplasia (4.3%), and others (8.6%). Age at presentation was less in patients with pheochromocytoma (33 years) and tuberculosis (41 years) compared with PAL (48 years) and metastases (61 years) (PAI) (95%). The presenting symptoms for PAL were AI (57%) and abdominal pain (43%), whereas all cases of metastasis had abdominal pain. Mean size of adrenal masses was the largest in lymphoma (5.5cm) followed by pheochromocytoma (4.8cm), metastasis (4cm) and tuberculosis (2.1cm) (P<0.001). Biochemically, most patients with pheochromocytoma (92.8%) had catecholamine excess. Hypocortisolism was common in tuberculosis (100%) and PAL (71.4%) and absent with metastases (P<0.001). Conclusion In evaluation of bilateral adrenal masses, age at presentation, presenting symptoms, lesion size, and biochemical features are helpful in delineating varied underlying aetiologies.

  17. US findings of bilateral primary breast cancer: Retrospective study

    International Nuclear Information System (INIS)

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index cancer

    Full Text Available Abstract Background Herpes zoster oticus accounts for about 10% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. Bilateral herpes zoster oticus can sometime occur in immunocompromised patients, though incidence is very rare. Case presentation Diabetic male, 57 year old presented to us with bilateral facial palsy due to herpes zoster oticus. Patient was having bilateral mild to moderate sensorineural hearing loss. Patient was treated with appropriate metabolic control, anti-inflammatory drugs and intravenous acyclovir. Due to uncontrolled diabetes, glucocorticoids were not used in this patient. Significant improvement in hearing status and facial nerve functions were seen in this patient. Conclusions Herpes zoster causes severe infections in diabetic patients and can be a cause of bilateral facial palsy and bilateral Ramsay Hunt syndrome. Herpes zoster in diabetic patients should be treated with appropriate metabolic control, NSAIDS and intravenous acyclovir, which we feel should be started at the earliest. Glucocorticoids should be avoided in diabetic patients.

    Little is known about the use of breast MRI as a diagnostic or surveillance tool in patients after bilateral mastectomy. The objective of this study was to evaluate breast MRI after bilateral mastectomy. Participants consisted of 48 women with prior bilateral mastectomy who underwent breast MRI between 2003 and 2009. Seventy-nine breast MRIs were obtained. The median time between mastectomy and first MRI was 36 months. MRI was ordered most often by a medical oncologist (71%). Median age at bilateral mastectomy was 49 years (range, 33 to 72 years). Reasons for obtaining MRI included surveillance in 60 (76%), mass in eight (10%), lymph nodes in four (5%), pain in three (4%), and abscess in one (1%). Overall, 68 (86%) MRIs showed benign imaging findings only. Within the surveillance group, six patients had MRIs with findings that changed management; four patients had some residual breast tissue, and two patients had findings outside the breast that were better evaluated by CT or bone scan and were ultimately benign. MRI confirmed locoregional recurrence in two patients with highly suspicious physical findings. Overall, postmastectomy breast MRI had limited use, finding no unsuspected recurrences within our study group. Although MRI can be helpful to establish the presence of residual breast tissue after bilateral mastectomy, subsequent routine screening breast MRI should be questioned if no residual breast tissue is identified.

    A seven-year-old, 41 kg, intact, cross breed dog, was presented with a history of bilateral hind limb lameness after falling from a height of 1 m. Clinical and radiographic findings were consistent with bilateral patellar tendon rupture. Surgical repair was performed bilaterally. The tendons were sutured primarily, and an internal splint of nylon leader was added. Good apposition of the severed tendon ends had been achieved intraoperatively; however, post operative radiographs showed supra-trochlear displacement of both patellae. The casts used to immobilize the stifle joints slipped distally and three days post operatively the tendon repair had broken down, bilaterally. Revision surgery was undertaken and the tendons were re-sutured. Nylon leader was placed through holes that had been drilled in the patellae and tibiae. The stifle joints were immobilized with type I external skeletal fixators (ESFs). Both freeform polymethylmethacrylate (PMMA) connecting bars were found to be broken at the level of the stifle joints two days later, without any disruption of the primary tendon repair. Each connecting bar was replaced with two connecting bars of PMMA reinforced with 3 mm steel wire. The dog was fully weight-bearing with a reduced range of motion in flexion immediately after removal of the ESFs at six weeks and was still sound 18 months post-operatively. Primary tendon repair in combination with adequate immobilization allowed for an excellent outcome in a complicated bilateral pathology. PMID:18545725

    Full Text Available Two female patients with histories of cancer who showed cryptogenic organizing pneumonia (COP complications and bilateral anterior uveitis with hypopyon were examined. Both patients had suffered from COP and received intermitted systemic corticosteroid administration (SCA. The first patient, a 65-year-old woman with a history of breast cancer, showed bilateral uveitis with hypopyon. The topical corticosteroid treatment was ineffective. After SCA for the treatment of COP was started, the hypopyon gradually dissipated. Upon termination of SCA, uveitis relapses were controlled by renewed SCA. The other patient, a 69-year-old woman with a history of ovarian cancer, showed bilateral anterior uveitis with hypopyon. Her intraocular outcome did not improve by the topical corticosteroid administration, but SCA that was applied to treat COP led to remission of uveitis. Imaging examinations, biochemical analysis, symptoms or HLA-B27 antigen screenings in either patient did not explain the development of uveitis. Bilateral anterior uveitis is commonly related to autoimmune disease or systemic syndrome. We report two cases with COP that developed bilateral anterior uveitis with hypopyon resistant to topical administration but responsive to systemic administration of corticosteroid. These findings suggest that COP can be associated with the etiology of anterior uveitis.

    A persistent trigeminal artery (PTA) is the most common anastomosis between the carotid and vertebrobasilar system. A PTA variant (PTAV) is a rare anomaly in which the cerebellar artery arises from the internal carotid artery (ICA) without connection with the basilar artery (BA). I present what I believe is the first report of bilateral PTAVs diagnosed using magnetic resonance (MR) angiography and briefly discuss the embryology of this rare anomaly. An 81-year-old woman with small infarctions underwent cerebral MR imaging and MR angiography with a 1.5-tesla imager for the evaluation of brain lesions. An MR angiography was obtained using the standard noncontrast three-dimensional time-of-flight technique. The MR angiographic demonstration of bilateral anterior inferior cerebellar arteries arising from the precavernous segment of the ICA without anastomosis to the BA indicated bilateral PTAVs. This is the first report of bilateral PTAVs diagnosed by MR angiography. The literature review indicates that an estimated prevalence of bilateral PTAVs is about 0.0012%. PMID:21544587

Material y métodos: Estudio cualitativo sobre una muestra de 60 personas, de 18-50 años de edad, que ejercen la prostitución en la calle, apartamentos y clubs de 6 ciudades españolas, mediante entrevista semiestructurada. Resultados: El alcohol y la cocaína son las principales sustancias de consumo en este contexto. Se trata de consumos ocasionales e instrumentales que permiten a las personas que ejercen la prostitución sobrellevar la actividad que realizan, resistir muchas horas la prestación de prácticas sexuales con diferentes clientes, obtener mayores beneficios económicos y eludir los servicios sexuales. Las consecuencias del consumo por parte de estas personas pueden llevar a la desprotección en las prácticas sexuales y a ser víctimas de agresión o violencia por parte del cliente. Las personas prostituidas desarrollan estrategias de disminución del consumo: reducción de las dosis de consumo, simulación del uso de drogas o selección de los clientes consumidores. Conclusiones: El estudio destaca que los consumos de drogas se encuentran asociados al contexto de realización de los servicios sexuales. Sin embargo, las consecuencias de éstos pueden implicar riesgos para la salud por la desprotección de las prácticas sexuales que demanda el cliente.Objective: To describe the circumstances and consequences of cocaine use in the setting of prostitution.

Pero, con independencia de tal aseveración, es definitiva la interpretación del precepto, según criterios y métodos jurídicos, en cuanto enuncia unos «valores» que el Estado constituido «propugna», que se califican como «superiores» y que se predican, precisamente, del «ordenamiento jurídico». La justicia es, desde luego y en sí misma, un valor, al que conviene la nota de clásico en la determinación de los que han de regir una convivencia política estable. Uno u otro sentido de la justicia ha latido con fuerza en la conciencia humana y en toda pretensión racional de ordenación de la convivencia.

    This case highlights the diagnostic challenges in patients presenting with bilateral sudden sensorinueral hearing loss (SNHL). The aetiology of bilateral sudden SNHL may span several medical disciplines. Therefore, clinicians should be mindful of such presentations, and consider aetiologies beyond otological and neurological causes. We present a case of a previously healthy 51-year-old woman who presented with coryzal symptoms and sudden audiovestibular failure. Examination revealed fever, tachycardia, bilateral profound hearing loss and nystagmus. Following investigations, an initial working diagnosis of vasculitis was made. Later, blood cultures revealed methicillin-sensitive Staphylococcus aureus (MSSA) and a transoesophageal echocardiogram confirmed endocarditis. The patient made a good recovery, but the hearing loss was permanent and managed with a cochlear implant.

    Based on the basic trade gravity model and Xinjiang's practical situation, new explanatory variables (GDP,GDPpc and SCO) are introduced to build an extended trade gravity model fitting for Xinjiang's bilateral trade. Fromthe empirical analysis of this model, it is proposed that those three variables affect the Xinjiang's bilateral trade posi-tively. Whereas, geographic distance is found to be a significant factor influencing Xinjiang's bilateral trade negatively.Then, by the extended trade gravity model, this article analyzes the present trade situation between Xinjiang and itsmain trade partners quantitatively in 2004. The results indicate that Xinjiang cooperates with its most trade partnerssuccessfully in terms of present economic scale and developing revel. Xinjiang has established successfully trade part-nership with Central Asia, Central Europe and Eastern Europe, Western Europe, East Asia and South Asia. However,the foreign trade development with West Asia is much slower. Finally, some suggestions on developing Xinjiang's for-eign trade are put forward.

In the bilateral breasts, ill-defined, firm masses with skin retraction were noted. Bilateral breast cancer was diagnosed clinically. However, both lesions showed histologically chronic granulomatous inflammation with foci of fatty necrosis, infiltration of lymphocytes, plasma cells, lipid containing foamy cells, foreign body giant cells engurfing choresterol-crystals, and calcification. "Paraffinoma" was thus suspected, but there was no history of cosmetic mammoplasty and histochemical studies failed to demonstrate saturated lipid indicating paraffin or other mineral oils

    Full Text Available A 72-year-old man presented with constipation. He was hypertensive and suffered from chronic constipation. On arrival, the patient was fully conscious, and his vital signs were stable. He requested an enema because this treatment had proved effective in the past. On physical examination, a hard palpable mass was detected in the lower abdomen. Computed tomography was performed with contrast media. It revealed an abdominal aortic aneurysm (AAA and bilateral internal iliac artery aneurysms (IIAAs; the latter obstructing the sigmoid colon. We believe that this obstruction was the cause of constipation. The patient underwent Y-graft replacement for the treatment of the AAA and bilateral IIAAs. The surgery was successful, and constipation has not recurred since. As constipation is the most common digestive disorder in the general population, all physicians should be aware that chronic constipation can be caused by bilateral IIAAs.

    Historically, the study of speech processing has emphasized a strong link between auditory perceptual input and motor production output. A kind of 'parity' is essential, as both perception- and production-based representations must form a unified interface to facilitate access to higher-order language processes such as syntax and semantics, believed to be computed in the dominant, typically left hemisphere. Although various theories have been proposed to unite perception and production, the underlying neural mechanisms are unclear. Early models of speech and language processing proposed that perceptual processing occurred in the left posterior superior temporal gyrus (Wernicke's area) and motor production processes occurred in the left inferior frontal gyrus (Broca's area). Sensory activity was proposed to link to production activity through connecting fibre tracts, forming the left lateralized speech sensory-motor system. Although recent evidence indicates that speech perception occurs bilaterally, prevailing models maintain that the speech sensory-motor system is left lateralized and facilitates the transformation from sensory-based auditory representations to motor-based production representations. However, evidence for the lateralized computation of sensory-motor speech transformations is indirect and primarily comes from stroke patients that have speech repetition deficits (conduction aphasia) and studies using covert speech and haemodynamic functional imaging. Whether the speech sensory-motor system is lateralized, like higher-order language processes, or bilateral, like speech perception, is controversial. Here we use direct neural recordings in subjects performing sensory-motor tasks involving overt speech production to show that sensory-motor transformations occur bilaterally. We demonstrate that electrodes over bilateral inferior frontal, inferior parietal, superior temporal, premotor and somatosensory cortices exhibit robust sensory-motor neural

    We report on an Italian boy, born to normal and nonconsanguineous parents with a prenatal diagnosis of ventriculomegaly and subependymal glial heterotopias. At birth bilateral macrostomia was diagnosed without other evident facial anomalies. Magnetic resonance imaging (MRI) showed triventricular hydrocephalus and aqueductal stenosis and confirmed the nodules of glial heterotopia. The bilateral macrostomia was surgically corrected with the vermilion square flap method and W-plasty technique and follow up MRI at 6 months showed mild increase of ventricular dilatation without signs of active hydrocephalus. The association between macrostomia and hydrocephalus has been reported only in rare cases of complex malformative syndromes but never with isolated macrostomia.
