    Full Text Available Introducción: El control prenatal se define como todas las acciones y procedimientos, sistemáticos y periódicos, destinados a la prevención, diagnostico y tratamiento de los factores que pueden coordinar la morbilidad y mortalidad materna y perinatal. La muerte de una madre es una tragedia evitable que afecta una vida joven llena de grandes esperanzas; es una de las experiencias más traumáticas que puede sufrir una familia y afecta seriamente el bienestar, la supervivencia y el desarrollo de los hijos, especialmente de los más pequeños. Todo lo anterior trae como consecuencia el debilitamiento de la estructura social en general. Materiales y Métodos: Es un estudio descriptivo de corte transversal, en el cual, se identificaron aspectos importantes como las variables sociodemográficas, clínicas, barreras de acceso y adherencia para el ingreso temprano al control prenatal de las gestantes que consultan a una unidad materno infantil. Resultados: El control prenatal representa una estrategia básica que permite identificar factores de riesgo y alteraciones fisiológicas en toda paciente gestante. Los resultados expresados en Le presente trabajo muestran el impacto favorable cuando no inciden las variables de riesgo. Discusión y Conclusiones: Queda demostrado que con un número suficiente de controles prenatales y efectuados en forma precoz, estas pacientes pueden ser contenidas en su situación y se llega a disminuir en forma muy importante la mortalidad perinatal.

    2001-01-01

    [spa] La satisfacción del usuario de los hospitales es un indicador de calidad de la asistencia prestada. Entendemos la satisfacción como la diferencia con signo positivo entre la calidad percibida al alta y las expectativas previas al ingreso hospitalario. Un factor determinante en estas impresiones es el diagnóstico que justifica el ingreso. Así, se establecieron tres grupos (catarata, hernia de la cavidad abdominal y parto) para analizar las diferencias entre las puntuaciones al alta y la...

    Full Text Available Este artículo hace una revisión de la literatura y describe un modelo general para entender el problema de la teoría óptima de impuestos cuando los hogares son compuestos de un solo miembro o dos miembros. En los trabajos iniciales de Mirrlees y Atkinson y Stiglitz los hogares estaban compuestos de un solo miembro. Sin embargo, la realidad presenta un situación distinta, yo describo un modelo donde la economía esta compuesta por hogares de un miembro o dos miembros. Esto introduce consideraciones de equidad horizontal y vertical. Para impuestos lineales los resultados del modelo de Sheshinski se mantienen; sin embargo, para el caso de impuestos óptimos al ingreso se deben tener en cuenta nuevos resultados.

    2014-02-01

    Full Text Available Ante las manifiestas limitaciones de los instrumentos clásicos del Estado de Bienestar para asegurar a todos los ciudadanos un mínimo de satisfactores, se han ensayado en la literatura especializada distintas alternativas. Mientras que un conjunto de intelectuales es partidario de garantizar el derecho al trabajo, por otro lado se han elevado cada vez con mayor fuerza las tesis de un ingreso básico universal como derecho incondicional por parte de todos los ciudadanos o residentes en un país determinado. A medio camino entre estas concepciones se ubican las propuestas de transferencias monetarias dirigidas a poblaciones en situación de vulnerabilidad social con el propósito de incluirlas socialmente.El propósito de este artículo es repasar las características de estas políticas en relación a la discusión sobre la centralidad del trabajo en nuestras sociedades.

    Full Text Available Antecedentes: Los cambios demográficos en México están aumentando la proporción de adultos mayores de 60 años en riesgo de inseguridad alimentaria. La desnutrición en este grupo de edad es frecuente en la comunidad pero se exacerba durante las hospitalizaciones frecuentes, lo que aumenta la morbi-mortalidad y los costos en los servicios de salud. Objetivo: Describir la frecuencia de desnutrición al ingreso hospitalario de pacientes mayores de 60 años. Diseño: Observacional, transversal y descriptivo. Ubicación: Hospital de tercer nivel de referencia. Sujetos: 97 pacientes mayores de 60 años de edad ingresados consecutivamente a los sectores de hospitalización durante un periodo de seis meses del año 2006. Intervenciones: Al ingreso se realizó la valoración nutricional mediante la aplicación de la Mini Valoración Nutricional (MNA: Mini Nutritional Assessment y la Valoración Global Subjetiva más la recolección de datos de laboratorio rutinarios (albúmina sérica y linfocitos totales y del estado socioeconómico y educativo. Resultados: De 97 pacientes incluidos, 48% sólo completaron educación primaria y 66% tenían ingresos económicos medios.

  13. Evaluación del estado nutricional según compartimentos somático, graso y proteico-visceral al ingreso en una unidad de cuidados intensivos

    Directory of Open Access Journals (Sweden)

    María Esther Rodríguez Delgado

    2014-12-01

    Full Text Available La alta prevalencia de malnutrición en el ámbito hospitalario continúa siendo un problema de especial relevancia en España en la actualidad debido al impacto negativo sobre la evolución clínica del paciente hospitalizado. Numerosos estudios evidencian tasas de desnutrición hospitalaria cercanas a un 33-50% de la población hospitalizada. Este impacto es mucho más importante y de mayor trascendencia cuando hablamos de pacientes críticos dentro de la unidad de Cuidados Intensivos. Estados nutricionales y metabólicos deficitarios tienen una repercusión directa sobre el enfermo, entorpeciendo la evolución clínica del enfermo e incrementando las tasas de morbimortalidad y de complicaciones hospitalarias así como los costes sanitarios derivados de ello. Desarrollar un adecuado abordaje nutricional mediante soportes nutricionales es un objetivo fundamental y un pilar básico para un óptimo manejo del paciente críticamente enfermo, pudiéndose ver obstaculizado en numerosas ocasiones, especialmente en pacientes que cursan con hipercatabolismo e hipermetabolismo con un consumo energético importante secundario al proceso patológico que motivó el ingreso. A todo ello hay que sumar la gran dificultad que supone una valoración integral y completa de su estado nutricional donde muchos de estos parámetros, encuestas nutricionales y pruebas funcionales puede resultar complicadas de realizar, poco fidedignos, o pueden aportan datos incorrectos, incompletos o con imposibilidad de su realización.

    2010-01-01

    Full Text Available Muchos de los programas sociales y la gran mayoría de los programas contra la pobreza, encuentran su fundamento en el supuesto de que un aumento en el ingreso de las personas se traduce, de manera automática, en un aumento de su bienestar. La presente investigación cuestiona este supuesto con base en la literatura de bienestar subjetivo y en el análisis empírico realizado con información de México. Se muestra que es posible sacar a las personas de la pobreza de ingreso, sin que esto se traduzca necesariamente en un aumento de su bienestar. Se sugieren algunos lineamientos generales para mejorar los programas sociales. Se argumenta que es bueno preocuparse por sacar a las personas de la pobreza de ingreso, pero es aún mejor preocuparse por ubicarlas en una situación que favorezca su satisfacción de vida.Many social programs, and most poverty-fighting programs, are based on the assumption that increasing income automatically translates into a raise in well-being. This investigation questions this assumption on the basis of the subjective well-being literature and on empirical analyses from Mexico. It is shown that it is possible to get people out of income poverty without necessarily increasing their well-being. The paper enunciates some general principles that can enhance social programs. It is argued that it is fine to be concerned about getting people out of income poverty, but it is even better to be concerned about placing them in a situation that favors their satisfaction with life.

Utilizando el concepto de cinemaeducación y a través de la implementación de ciclos de cineforos, se persiguieron dos objetivos fundamentales. Por un lado, se estudió la incidencia del cineforo en el desarrollo de un diseño de gestión administrativa que produjera nuevas formas de generar ingresos propios y por el otro, se concibió al cineforo como estrategia didáctica, que beneficiase en lo particular a los estudiantes del referido Departamento y a otros miembros de la comunidad universitaria. Se recoge que los resultados de esta experiencia de investigación indican que la modalidad de cineforo es productiva como actividad generadora de ingresos propios y como estrategia didáctica innovadora, empleando estímulos visuales, auditivos y experienciales. Se concluye que el cineforo resultó ser una estrategia didáctica extra-muros que promueve la participación activa, responsable y comprometida de las personas y entes involucrados en el proceso educativo, de forma innovadora, creativa e integradora.

    la distribución modal de los ingresos muestra la existencia de una fuerte correlación entre la calidad del transporte público y la distribución del ingreso de los usuarios, que no puede explicarse sólo por las tarifas. La serie de datos recopilados en los últimos años permiten un análisis econométrico de la evolución de la tendencia. Una serie de entrevistas con el metro y los administradores de metro-bus, así como sociólogos y psicólogos sociales han ayudado a identificar las variables sociológicas de mayor influencia en el comportamiento de viaje de la población de altos ingresos y los atributos de calidad de metro y autobús de metro con más atractivo. Los resultados podrían ser indicativos de cómo las políticas de éxito para inducir un cambio en la elección modal de los vehículos al transporte público, podría ser aplicado incluso en ciudades donde la segregación social es extrema.

    Full Text Available Objetivo: Estimar la asociación de los ingresos económicos del hogar y de la renta provincial con las consultas al médico general y al especialista y con la hospitalización. Estimar si el tiempo de espera para acceder a esos servicios varía con esas características. Método: Datos de la Encuesta Nacional de Salud de 2001. La asociación se estimó mediante la odds ratio, ajustada por edad y sexo, y en el caso de la renta per cápita se ajustó también por los ingresos económicos del hogar. Se estimaron los percentiles y la media geométrica de los tiempos de espera en cada servicio sanitario y se evaluó la significación estadística de su asociación con ambas variables económicas. Resultados: Los sujetos con menores ingresos económicos presentan la mayor frecuencia de consultas al médico general y hospitalización, aunque esperan más tiempo para ser hospitalizados. Estos sujetos presentan la menor frecuencia de consultas al especialista: la odds ratio en el cuartil más bajo de ingresos frente al más alto fue 0,73 (intervalo de confianza del 95%, 0,62-0,87, aunque en las consultas financiadas públicamente la menor frecuencia se observa en los sujetos con mayores ingresos. No se han encontrado diferencias en la utilización y en los tiempos de espera según la renta provincial. Conclusiones: La frecuencia de consultas al especialista según los ingresos económicos del hogar muestra un patrón distinto al observado en las consultas al médico general y en la hospitalización. El mayor tiempo de espera para hospitalización se observa en los sujetos con menores ingresos económicos.Objective: To estimate the association of household income and provincial income with visits to general practitioners and specialists and with hospitalization and to determine whether waiting times to access these services vary with both economic variables.

    Full Text Available La teoría de la atribución y los hallazgos acerca de iniciativas de negocio dirigidas a los consumidores de bajos ingresos sugieren que el entrenamiento de los gerentes con respecto a estos consumidores podría influir sobre sus atribuciones y expectativas de éxito en tales iniciativas. Para analizar las relaciones entre estas variables se llevó a cabo un estudio descriptivo correlacional sobre una muestra de 370 estudiantes de gerencia, que se desempeñaban como gerentes medios en organizaciones que atienden a consumidores de bajos ingresos. Los resultados mostraron relaciones entre el entrenamiento y la atribución de características de sociabilidad a estos consumidores, y entre la atribución de sociabilidad y las expectativas de éxito con ofertas tradicionales. La mayoría de los participantes no ha recibido entrenamiento para el trabajo con estos consumidores, lo cual confirma hallazgos referidos a la dificultad para desarrollar ofertas innovadoras: desconocimiento y distanciamiento.

    Full Text Available FUNDAMENTO: Las prisiones españolas albergan un elevado número de usuarios de drogas por vía parenteral (UDVP, y otras personas con prácticas de riesgo para la infección por virus de la inmunodeficiencia humana (VIH. El objetivo de este trabajo es conocer la evolución de la prevalencia de infección por VIH en el momento del ingreso en prisión y los factores asociados a la misma en este colectivo, lo que puede permitir una aproximación a la efectividad de las estrategias de reducción de riesgos y contribuir a mejorarlas. MÉTODOS: Todas aquellas personas que ingresaron en un centro penitenciario provincial del noroeste español entre los años 1991 y 1995. Se recogieron variables socio-demográficas, penitenciarias y factores de riesgo para VIH. Previo consentimiento, se practicó prueba de infección por VIH (ELISA y Western-blot. RESULTADOS: El 19,4% de los 1663 individuos estudiados estaban infectados por VIH. Destacaban, con significación estadística, las prevalencias en: mujeres (26,0%, el grupo de edad desde 25 a 34 años (29,1%, blancos (20,9%, solteros (22,8%, tatuados (29,9%, los que presentaban antecedentes de autolesiones (42,4%, los UDVP (46,3%, los que reconocieron compartir jeringuillas (61,5 % y aquellos con antecedentes de haber permanecido en prisión un año o más (37,3%. El análisis de regresión logística mostró como predictores de infección VIH: los UDVP, los que ingresaron en 1992, las mujeres, los grupos de edad de 25-34 y de 35-44 años, los tatuados, los que presentaban antecedentes de autolesiones y aquellos con antecedentes de estancia en prisión superior a un año. La etnia gitana presentó menor probabilidad de infección por VIH. La tendencia temporal de la infección VIH estratificada según el antecedente de estancia previa en prisión, mostró un descenso casi significativo (P=0,064. La tendencia de la infección según UDVP no mostró modificación (P=0,16. CONCLUSIONES: Se ha detectado una

    2009-01-01

    Full Text Available La aplicación, a partir de 1980, de las políticas económicas neoliberales que buscaron fundamentalmente el desmantelamiento del Estado de bienestar, condujo al incremento en los niveles de concentración del ingreso y al aumento de la pobreza no sólo en los países subdesarrollados sino también en los industrializados. Este artículo presenta evidencia estadística de este fenómeno en los Estados Unidos de América, y en particular se ocupa de la manera en que el mismo afecta a los grupos más marginados de la sociedad capitalista moderna. Asimismo, se constata que en las décadas anteriores a 1980, época en la que se llevaron a cabo las políticas económicas y sociales del Estado de bienestar, se logró abatir los niveles de pobreza en los Estados Unidos y la concentración del ingreso permaneció estable, en contraste, luego de la aplicación de las políticas económicas neoliberales, se agudizó la concentración del ingreso en las capas altas de la sociedad.

    Full Text Available Este artículo compara los efectos de los programas de renta básica con los de transferencias condicionadas que se han adoptado en América Latina, tomando el Programa Oportunidades en un área metropolitana de México. Mediante una estimación de tipo Kernel se encontró que no existen diferencias estadísticas en el ingreso de los hogares que tienen y los que no tienen transferencias condicionadas. En cambio, un ingreso equivalente al umbral de extrema pobreza o de un salario mínimo genera diferencias estadísticamente significativas en el poder adquisitivo que ayudan a superar la pobreza extrema.

    Full Text Available El presente artículo tiene como objetivo explicar cómo el entorno macroeconómico, puede ser un factor determinante del comportamiento de los ingresos operacionales de las empresas de los sectores más representativos de Colombia. La metodología empleada fue panel de datos con efectos fijos o aleatorios, según el resultado de la prueba correspondiente. Se analizaron los sectores energía, químico; construcción; comercio y otros servicios, entre 1998-2009. Los resultados mostraron que las variables macroeconómicas más influyentes en el desempeño de los ingresos corporativos son la tasa de interés y variación del índice de tasa de cambio real en los sectores químico y otros servicios; la tasa de desempleo en los sectores energía y construcción; y la tasa de inflación en el sector agropecuario. Pese a que las empresas del sector comercio no mostraron significancia estadística ante las variables macroeconómicas; el desempeño del PIB y la variación de la tasa de cambio real pueden determinar sus ingresos. En términos generales se verificó la respuesta diferencial de las empresas colombianas al contexto económico predominante a nivel departamental y nacional.

    2013-01-01

    Full Text Available En esta investigación se evalúa una hipótesis que sostiene que en las comunidades rurales la reciente migración internacional ha inducido una mayor desigualdad en la distribución del ingreso (Stark, Taylor y Yitzhaki, 1986. Para analizar el efecto de las remesas internacionales sobre la distribución del ingreso en una muestra de 37% de los hogares en San Miguel Coatlán, Oaxaca, se ha utilizado la descomposición del coeficiente de Gini por fuentes de ingreso. Los resultados muestran que si bien en esta comunidad se advierte una fuerte desigualdad, las remesas mejoran la distribución; la historia migratoria no decide la forma de la distribución, sino que depende más bien de la estructura de los hogares que perciben las remesas, de la importancia de éstas respecto a los demás ingresos, y de ciertas formas culturales que propician la incorporación a la migración de algunos miembros de hogares de todos los estratos económicos de la comunidad.

    Full Text Available En la última década los niveles de desigualdad en la distribución del ingreso se han reducido significativamente en América Latina. Esto producto de un crecimiento económico sostenido y la marcada reducción de los niveles de pobreza. No obstante, en términos internacionales la región continúa siendo la más desigual del planeta manteniendo altos niveles de concentración del ingreso. Aunado a esto, las mediciones sobre desigualdad, provenientes de encuestas de los hogares, podrían estar subestimando la alta concentración del ingreso al compararse con mediciones provenientes de registros fiscales, al mismo tiempo que las estructuras tributarias se encuentran sesgadas hacia impuestos indirectos con un más regresivo impacto distributivo. Este artículo propone la incorporación de instrumentos de análisis, basados en los registros tributarios, que permitan mejorar las mediciones sobre la desigualdad, así como cambios en materia impositiva a fin de de aumentar la recaudación y el alcance efectivo de los impuestos sobre los individuos de más altos ingresos.

    Full Text Available FUNDAMENTO: En este trabajo se trata de establecer, respecto al servicio de urgencias del hospital Juan Catalejo de A Coruña, las posibles asociaciones entre el número de ingresos por causas orgánicas, cardiovasculares y respiratorias, y las variables meteorológicas introducidas como variables exógenas con el fin de elaborar un modelo de predicción. MÉTODOS: Se utilizó la metodología de Box-Jenkins para obtener modelos ARIMA univariados de las series temporales consideradas. Se establecen funciones de correlación cruzada (FCC entre las series de residuales que permitan establecer pesos y retrasos entre las variables, para una posterior modelización mediante modelos ARIMA multivariantes que incluyen variables ambientales. El periodo de tiempo estudiado fue de 1994 a 1996. RESULTADOS: Los ingresos urgentes por causas orgánicas aumentan significativamente entre 0 y 2 días después de un ascenso de la temperatura ambiental. Los ingresos por causas respiratorias se asocian con los descensos de temperatura con 10-14 retrasos, mientras que los ingresos por causas circulatorias se ven aumentados significativamente por el calor a largo plazo (10 retrasos. En mayores de 65 años se registran, además, aumentos significativos de los ingresos urgentes por causas circulatorias, en relación con el frío, a corto plazo. Los modelos ARIMA multivariantes que contemplan el efecto de variables ambientales ofrecieron un mejor ajuste para todas las variables de ingresos. CONCLUSIONES: El número de ingresos en el servicio de urgencias en el Complejo Hospitalario Juan Canalejo de A Coruña por causas orgánicas, respiratorias y circulatorias, presenta un patrón de comportamiento estacional. Los ingresos por causas respiratorias están asociados al descenso de la temperatura ambiental, mientras que los ingresos por causas circulatorias se ven afectados fundamentalmente por el calor, aunque también por el frío, en mayores de 65 años.

    Full Text Available Este artículo tiene como objetivo proporcionar una medición de las elasticidades de los principales impuestos del sistema tributario costarricense, de manera que permita dar señales sobre los efectos que se pueden percibir conforme sucedan los cambios en la economía y que contribuya al análisis de las situación fiscal del país.  Las estimaciones de las elasticidades se obtienen por medio de la aplicación de un modelo de regresión y se estiman las elasticidades de corto y largo plazo. Las elasticidades tributarias miden el cambio que experimentan los ingresos tributarios ante cambios en el ingreso o producción nacional. Si la recaudación depende de varios factores, lo fundamental es determinar para cuál factor es útil calcular la elasticidad, a la vez, debe tenerse presente que el valor de la elasticidad depende básicamente de la estructura impositiva y de la progresividad del sistema. La elasticidad de la recaudación tributaria es una variable de gran importancia en los análisis de la evolución fiscal y para las proyecciones de ingresos tributarios. Los resultados muestran que la elasticidad de largo plazo de los ingresos presenta un comportamiento elástico con respecto a las bases que se especificaron para cada impuesto.

(1999 para medir la polarización con el objetivo de cuantificar el deterioro de la clase media durante 1984-2000 en México. Se asume que la formación extrema de grupos en cualquier sociedad es determinada por el ingreso del hogar. Se utilizan las bases de datos desagregadas de la Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH en el cálculo de los índices, ajustando el ingreso familiar disponible con la escala de equivalencia de la OCDE, y se emplea la técnica de bootstraps en la inferencia.

    Full Text Available Este trabajo pretende evaluar, para el caso colombiano, si la inflación aumenta la desigualdad del ingreso al perjudicar a los más pobres. Con la ayuda de las teorías de salarios rezagados y deudor-prestamista, asó como también de estudios empíricos a nivel internacional, se presentan las formas cómo la inflación afecta la distribución del ingreso. Se encuentra que la inflación no afecta necesariamente a los más pobres y, por el contrario, puede ser progresiva como ha ocurrido en otros países. Para Colombia, la evidencia empírica indica que la inflación no ha sido regresiva debido a que hubo una inflación de tipo inercial muy estable durante un largo período, sin haber llegado a niveles de hiperinflación como en otras economías latinoamericanas.This paper tries to assess, for the Colombian case, if inflation raises income inequality by damaging the poorest people. With the help of the lagged wages and debtor-creditor theories, among other, as well as empirical works at international level, it shows the ways inflation affects income distribution. It finds that inflation does not necessarily affect the poorest people and, on the contrary, inflation may be progressive as it has happened in other countries. In Colombia, the empirical evidence shows that inflation has been not regressive because there was an inertial inflation very fixed for a long period, without getting hyperinflation levels as in other Latin-American economies.

    Full Text Available Las discusiones conceptuales en América Latina acerca del comportamiento socioeconómico de la región y de las evidencias sobre los rasgos dominantes de inequidad se han focalizado en las últimas décadas en torno de las medidas de dispersión o de concentración del ingreso percibido por las personas o las familias. Sin embargo, no han incluido, por lo general, el referido a la manera en que los factores productivos logran apropiarse de la riqueza que anualmente se genera en cada uno de nuestros países. El propósito básico de este artículo es llamar la atención en tal sentido. Para tal fin, se menciona la escasa producción académica al respecto en nuestra región al tiempo que se alude a la no muy abundante información disponible. Todo ello se ilustra con el caso de Argentina.

    Full Text Available Las fluctuaciones y los cambios estructurales económicos representan conceptos claves para el análisis de datos de coyuntura. Constituyen la materia prima para la estimación y predicción de variables representativas de la actividad económica de un país. Los cambios estructurales son acontecimientos especialmente relevantes en el análisis de la coyuntura económica que se examinan con especial atención, sobre todo por sus implicancias. Las fluctuaciones amplían sustancialmente el conocimiento sobre el sistema económico, de modo que pueden explicar con mayor fundamento el comportamiento de las variables analizadas y obtener predicciones y diagnósticos más precisos. En base a los datos obtenidos de la Dirección Nacional de Coordinación Fiscal con las Provincias, dependiente del Ministerio del Interior de la Nación, se realiza un análisis descriptivo del comportamiento de la recaudación del impuesto sobre los Ingresos Brutos de las provincias de la región del Noroeste Argentino -Catamarca, Jujuy, Salta, Santiago del Estero y Tucumán- en el período comprendido entre 1983 y 2002. También se ha considerado importante agregar la relación entre la recaudación del tributo y el Producto Bruto Interno (PBI, en cada una de las provincias, a efectos de medir su incidencia y disponer de un coeficiente de comparación interjurisdiccional de eficiencia tributaria por parte de la entidad recaudadora. Finalmente y en función de la disponibilidad de datos mensuales de la recaudación de la Provincia de Tucumán, se realiza un análisis de la serie correspondiente al tributo Ingresos Brutos, en el período enero de 1987 a junio de 2003, muy representativo para medir el nivel de actividad económica de nuestra provincia. El método estadístico, para esta parte del trabajo, se basa en un análisis de series cronológicas con enfoque estructural de espacio de estado.

El Indice de Percepción de Corrupción (un indicador indirecto del capital social fue usado para incluir más países en desarrollo en el análisis. Fueron calculados los coeficientes de correlación de Spearman entre el índice de Gini con las demás variables independientes. El análisis de trayectoria fue realizado para evaluar el efecto de la desigualdad de renta, de los proxys de capital social y del régimen político en la esperanza de vida. RESULTADOS: Los coeficientes de trayectoria sugieren que la desigualdad en la renta tiene un mayor impacto directo sobre la esperanza de vida al nacer que a través del capital social. El régimen político actúa sobre la esperanza de vida al nacer a través de la desigualdad en el ingreso. CONCLUSIONES: La desigualdad en la renta y el capital social tienen efectos directos sobre la esperanza de vida al nacer. El modelo de régimen de "clase/bienestar" puede ser útil para entender las desigualdades sociales y de salud entre países, mientras que la "hipótesis de desigualdad en la renta" es solo una aproximación parcial útil para analizar diferencias dentro de cada país.OBJETIVO: Analisar se a relação entre a desigualdade de renda e a saúde humana é mediada pelo capital social, assim como a influência do regime político na distribuição de renda nos países. MÉTODOS: Estudo ecológico de trajetórias utilizando dados transversais de 110 países. A variável de desfecho foi a esperança de vida ao nascer; as variáveis independentes foram: desigualdade de renda (medida pelo índice de Gini, capital social (medido pelo índice de percepção de corrupção ou confiança generalizada e regime político (medido pelo Índice de Liberdade.

    Full Text Available La sociedad brasileña convive con modificaciones en el modo de gestión del patrimonio público. Parte de esas modificaciones puede ser atribuida a la edición de la Ley de Responsabilidad Fiscal (LRF, una vez que creó reglas rígidas para la renuncia de ingresos públicos. Analizar las normas de finanzas públicas que imponen límites y condiciones para alcanzar responsabilidad en la gestión fiscal, en especial, en lo que se refiere a la concesión de beneficios por medio del instituto de la renuncia de ingresos, tiene gran relevancia como una contribución social. El objetivo de este estudio consiste en proveer una reflexión sobre doctrina y jurisprudencia del Tribunal de Cuentas de la Unión y del Estado de Minas Gerais, que establecen condiciones restrictivas para la renuncia de ingresos públicos. La pesquisa se caracteriza como exploratoria y utiliza como fuentes documentales legislación, doctrina y jurisprudencia del Tribunal de Cuentas de la Unión y del Tribunal de Cuentas del Estado de Minas Gerais, a fin de subsidiar apuntamientos inferenciales sobre la temática. Los resultados del estudio indican algunos avances en relación a la renuncia de ingresos en el Brasil: 1 la LRF representa el primer avance al imponer restricciones a la concesión de ese beneficio; 2 la Secretaría del Tesoro Nacional creó la metodología de deducción de ingresos, promoviendo, con eso, una mayor evidenciación de esos valores; 3 los Tribunales de Cuentas fiscalizan la obediencia de los límites establecidos para renuncia de ingresos.

    Full Text Available El sector de la comunicación no es ajeno a la crisis y sus correlatos. La bajada de la inversión publicitaria está teniendo consecuencias drásticas que se manifiestan, por ejemplo, en un reajuste en su estructura de ingresos. Además de esta crisis “coyuntural” –aunque larga-, hay otra que afecta significativamente a las empresas periodísticas: la reducción paulatina de lectores de medios impresos. En este estudio se parcela esta tipología de empresas de comunicación, centrándonos en aquellas que tienen como output las revistas. Y, para que el universo se reduzca aún más, abordaremos aquellas que se califican como “de alta gama”, que por su exclusiva idiosincrasia se sitúan ante el contexto económico imperante de una forma distinta.  De ellas, se analizará su estructura económica, en concreto, los ingresos provenientes de la publicidad, aunque de manera tangencial, se estudiará su precio de venta al número y su tirada. Con una metodología sustentada en el análisis cualitativo, con transposición cuantitativa, pretendemos conocer la cuantía de ingresos que perciben tres de estas arquetípicas revistas en un mes a través de la publicidad que muestra el prototipo de belleza actual. Para llegar a corroborar –o no- la siguiente hipótesis: “las revistas de alta gama, como medios de comunicación impresos no diarios, son un vehículo de la expresión de la belleza y, a través de ella, se consiguen ingresos sustanciales”.

    Five to ten percent of amyotrophic lateral sclerosis (ALS) cases are associated with mutations of the superoxide dismutase-1 (SOD1) gene, and the 'D90A' mutation is associated with a unique phenotype and markedly slower disease progression (mean survival time 14 years). Relative sparing of inhibitory cortical neuronal circuits might be one mechanism contributing to the slower progression in patients homozygous for the D90A mutation (homD90A). The GABA(A) receptor PET ligand [11C]flumazenil has demonstrated motor and extra-motor cortical changes in sporadic ALS. In this study, we used [11C]flumazenil PET to explore differences in the pattern of cortical involvement between sporadic and genetically homogeneous ALS groups. Twenty-four sporadic ALS (sALS) and 10 homD90A patients underwent [11C]flumazenil PET of the brain. In addition, two subjects homozygous for the D90A mutation, but without symptoms or signs ('pre-symptomatic', psD90A), also underwent imaging. Results for each group were compared with those for 24 healthy controls of similar age. Decreases in the binding of [11C]flumazenil in the sALS group were found within premotor regions, motor cortex and posterior motor association areas. In the homD90A group of ALS patients, however, decreases were concentrated in the left fronto-temporal junction and anterior cingulate gyrus. In the two psD90A subjects, a small focus of reduced [11C]flumazenil binding at the left fronto-temporal junction was seen, similar to the pattern seen in the clinically affected patients. Within the sALS group, there was no statistically significant association between decreases in cortical [11C]flumazenil binding and revised ALS functional rating scale (ALSFRS-R score), whereas the upper motor neuron (UMN) score correlated with widespread and marked cortical decreases over the dominant hemisphere. In the homD90A group, there was a stronger statistical association between reduced cortical [11C]flumazenil binding and the ALSFRS-R, rather

Los hogares con mayores ingresos consumieron más tabaco que los hogares de menores ingresos, sin embargo, los hogares de más bajos ingresos destinaron un porcentaje más importante de éstos al consumo de tabaco.Objective. To analyze selected determinants of tobacco consumption in Mexican homes. Material and Methods. Data from the National Household Income and Expenditure Survey, 1984-2000, were analyzed. The analysis was conducted for the years 1984-1992 and 1994-2000. The likelihood of tobacco consumption in households was estimated with a logistic regression model. Results. Tobacco consumption during the first period was two times more likely from decile six (OR=2.03, 95%, CI: 2.03-2.04 and during the second period from decile eight (OR=2.06, 95%, CI: 2.05-2.07. Households from decile one spent on average 9-22% of their income on tobacco; almost all of the households from decile ten spent only 1% of their income on tobacco. Conclusions. Households with higher income consumed more tobacco than households with low income; nevertheless, households with the lowest income devoted a greater proportion of income to tobacco consumption.

En un estudio reciente de nuestro laboratorio examinamos si el daño cerebral focal puede alterar de forma selectiva la descripción de los componentes de manera y de trayectoria (representados en inglés por verbos y preposiciones, respectivamente de un evento, y si se usan gestos para compensar la alteración del habla. Pedimos a pacientes con daño en el hemisferio izquierdo o derecho y participantes de control de la misma edad que describieran eventos de movimiento (p.ej., una persona caminando alrededor de algo presentados mediante videos breves. Los resultados sugieren que la producción de verbos y preposiciones puede verse afectada de forma independiente en el hemisferio izquierdo y que los gestos compensan las dificultades de denominación cuando el daño implica áreas concretas del córtex temporal izquierdo.

    Full Text Available A partir del análisis de las cuentas nacionales de México por sector institucional se descubre una relación de sustitución perfecta entre el ahorro externo y el ahorro interno. Cambios en la disponibilidad de ahorro externo generan, mediante diferentes mecanismos, variaciones en el mismo sentido en la participación de los salarios y los dividendos en el producto y en sus propensiones al consumo; y en sentido opuesto en el ahorro interno de las empresas. La relación de causalidad es clara; a mayor disponibilidad de ahorro externo mayor ingreso de los hogares y mayor consumo, no al revés. Mediante una reformulación del modelo de N. Kaldor, (1955, para incluir el ahorro externo y diferenciando las ganancias entre dividendos y ganancias retenidas, se formalizan y estiman, econométricamente, las relaciones entre los coeficientes de inversión, ahorro externo y dividendos por un lado y la distribución del ingreso entre salarios y ganancias por otro. Se resalta la importancia estratégica que la conducta económica de los dirigentes empresariales, manifiesta en las decisiones de inversión y en la propensión a distribuir las ganancias , ejerce sobre el crecimiento económico la distribución del ingreso, el consumo, el ahorro y la balanza de pagos. Hasta hoy, México se ha endeudado con el exterior para aumentar su consumo no para ampliar su planta productiva.

En este artículo indagamos en qué medida ambos procesos dan forma al reparto del trabajo doméstico entre parejas de doble provee - dor que difieren por tipo de unión. Basamos el análisis empírico en la ENIGH 2010 utilizando modelos de regresión. Nuestros resultados sugieren que la brecha de género en el trabajo doméstico es menor en las parejas en unión libre en comparación con las pa - rejas casadas, aun tomando en cuenta efectos de selección. Entre las primeras, la brecha se reduce mayormente conforme aumenta el ingreso, de modo que las parejas en unión libre y de alto ingreso representan el arreglo más equitativo en la división sexual del trabajo no remunerado. Ello se debe a que las mujeres en unión libre dedican menos tiempo al trabajo doméstico que las casadas, mientras que entre los varones no observamos diferencias.

    Full Text Available La malaria Cerebral (MC es la complicación más frecuente de la malaria por P. falciparum; aproximadamente el 90% de las personas que la han padecido se recuperan completamente sin secuelas neurológicas. Aún no se conoce con claridad su patogénesis pero se han postulado cuatro hipótesis o mecanismos posibles: 1 citoadherencia y secuestro de glóbulos rojos parasitados en la microvasculatura cerebral; 2 formación de rosetas y aglutinación de glóbulos rojos parasitados; 3 producción de citoquinas y activación de segundos mensajeros y, 4 apertura de la barrera hematoencefálica. Sin embargo, queda un interrogante sin resolver aún: ¿qué proceso se lleva a cabo para que el parásito, desde el espacio microvascular, pueda interferir transitoriamente con la función cerebral? Recientemente se ha utilizado el precursor de la proteína b-Amiloide como un marcador de daño neuronal en MC; este precursor será de gran ayuda en futuras investigaciones realizadas en nuestro medio que aporten información para comprender la patogénesis de la MC. Is the most common complication of P. falciparum malaria; nearly 90% of people who have suffered CM can recover without neurological problems. Currently there are four hypotheses that explain pathogenesis of CM: cytoadherence and sequestering of parasitized red blood cells to cerebral capillaries; rosette formation and parasitized red blood cells agglutination; production of cytokines and activation of second messengers and opening of the blood-brain barrier. However the main question remains to be answered; how the host-parasite interaction in the vascular space interferes transiently with cerebral function? Recently, the beta amyloid precursor peptide has been employed as marker of neural injury in CM. It is expected that the beta amyloid precursor peptide will help to understand the pathogenesis of CM in complicated patients of endemic areas of Colombia.

    Garcia-Ramirez, Jaime Antonio

    En esta investigacion, se desarrollo un instrumento que permite medir percepciones relacionadas al contexto de constriccion del conocimiento cientifico. Se examinaron instrumentos existentes y se encontro que el VOSTS (Views on science, technology, and society), instrumento desarrollado empiricamente en Canada por Aikenhead, Ryan y Fleming, podia traducirse y validarse en el contexto cultural puertorriqueno. El instrumento es extenso, consta de 113 reactivos, cada uno con una premisa basica relacionada a la tematica ciencia, tecnologia y sociedad y un numero de alternativas relacionadas a la premisa que oscila entre siete y trece. Se delimito su utilizacion a los quince reactivos identificados por los autores como relacionados a la construccion social del conocimiento cientifico. Metodologicamente, se procedio a utilizar el modelo de adaptacion intercultural, que permite que el instrumento desarrollado satisfaga las dimensiones de equivalencia semantica, de contenido, tecnica, de criterio y conceptual, atemperado asi al instrumento original.

    Garcia-Ramirez, Jaime Antonio

    En esta investigacion, se desarrollo un instrumento que permite medir percepciones relacionadas al contexto de constriccion del conocimiento cientifico. Se examinaron instrumentos existentes y se encontro que el VOSTS (Views on science, technology, and society), instrumento desarrollado empiricamente en Canada por Aikenhead, Ryan y Fleming, podia traducirse y validarse en el contexto cultural puertorriqueno. El instrumento es extenso, consta de 113 reactivos, cada uno con una premisa basica relacionada a la tematica ciencia, tecnologia y sociedad y un numero de alternativas relacionadas a la premisa que oscila entre siete y trece. Se delimito su utilizacion a los quince reactivos identificados por los autores como relacionados a la construccion social del conocimiento cientifico. Metodologicamente, se procedio a utilizar el modelo de adaptacion intercultural, que permite que el instrumento desarrollado satisfaga las dimensiones de equivalencia semantica, de contenido, tecnica, de criterio y conceptual, atemperado asi al instrumento original. Se cumplio con este proposito mediante la traduccion de la version original en ingles al espanol y viceversa. Se utilizaron comites para examinar la traduccion y la retro-traduccion del instrumento. Se realizo una prueba piloto con estudiantes universitarios de nuevo ingreso, utilizando el instrumento traducido para asegurar su intelegibilidad.

    Cerebral palsy is the most common cause of childhood-onset, lifelong physical disability in most countries, affecting about 1 in 500 neonates with an estimated prevalence of 17 million people worldwide. Cerebral palsy is not a disease entity in the traditional sense but a clinical description of children who share features of a non-progressive brain injury or lesion acquired during the antenatal, perinatal or early postnatal period. The clinical manifestations of cerebral palsy vary greatly in the type of movement disorder, the degree of functional ability and limitation and the affected parts of the body. There is currently no cure, but progress is being made in both the prevention and the amelioration of the brain injury. For example, administration of magnesium sulfate during premature labour and cooling of high-risk infants can reduce the rate and severity of cerebral palsy. Although the disorder affects individuals throughout their lifetime, most cerebral palsy research efforts and management strategies currently focus on the needs of children. Clinical management of children with cerebral palsy is directed towards maximizing function and participation in activities and minimizing the effects of the factors that can make the condition worse, such as epilepsy, feeding challenges, hip dislocation and scoliosis. These management strategies include enhancing neurological function during early development; managing medical co-morbidities, weakness and hypertonia; using rehabilitation technologies to enhance motor function; and preventing secondary musculoskeletal problems. Meeting the needs of people with cerebral palsy in resource-poor settings is particularly challenging. PMID:27188686

Para esto se utilizan herramientas de creciente aceptación, como alternativas para estudiar la dinámica en las desigualdades regionales: las cadenas de Markov y las funciones de densidad. En este caso, el análisis se desagrega hasta el municipio, con el objetivo de conocer cómo interactúan dichas unidades económicas entre sí, un contexto que tendría que enriquecer la literatura del tema, aún escasa en comparación con los trabajos que emplean metodologías predominantes, como la ecuación clásica de convergencia. Los resultados indican que en los municipios hay una inmovilidad relativa en términos de ingresos, es decir, que no hay cambios importantes en su distribución, la cual, a la vez, se encuentra polarizada.

    Full Text Available Política Fiscal y Distribución de Ingresos This paper studies the distributional implications of fiscal policy. After a review of the Chilean experience in the eighties, a general equilibrium, two period optimizing model is developed to evaluate the welfare effects of fiscal adjustment following an increase in the external payments of the publicly held external debt. The model considers two private sector representative agents: a capitalist and a worker. The government finances the external transfer with an internal transfer. The following fiscal policies are analvzed: lump sum transfers, direct taxes, inflation tax, public investment, and public debt. There are three channels by which the adjustment policy affects the welfare of private agents. The first channel is the direct impact of fiscal policy on private sector agents income. The second channel is related to the impact of the adjustment policy on growth and future income. Third, a current adjustment causes a future fical deficit which then involves an additional internal transfer between private sector agents.

    1975-01-01

    The first case of cerebral paragonimiasis was reported by Otani in Japan in 1887. This was nine years after Kerbert's discovery of the fluke in the lungs of Bengal tigers and seven years after a human pulmonary infection by the fluke was demonstrated by Baelz and Manson. The first case was a 26-year-old man who had been suffering from cough and hemosputum for one year. The patient developed convulsive seizures with subsequent coma and died. The postmortem examination showed cystic lesions in the right frontal and occipital lobes. An adult fluke was found in the occipital lesion and another was seen in a gross specimen of normal brain tissue around the affected occipital lobe. Two years after Otani's discovery, at autopsy a 29-year-old man with a history of Jacksonian seizure was reported as having cerebral paragonimiasis. Some time later, however, it was confirmed that the case was actually cerebral schistosomiasis japonica. Subsequently, cases of cerebral paragonimiasis were reported. However, the majority of these cases were not confirmed histologically. It was pointed out that some of these early cases were probably not Paragonimus infection. After World War II, reviews as well as case reports were published. Recently, investigations have been reported from Korea, with a clinicla study on 62 cases of cerebral paragonimiasis seen at the Neurology Department of the National Medical Center, Seoul, between 1958 and 1964. In 1971 Higashi described a statistical study on 105 cases of cerebral paragonimiasis that had been treated surgically in Japan.

Para el análisis distribucional se han confi gurado distintas regiones con base en el diferente grado de exposición que han tenido las entidades federativas del país ante el proceso de apertura de la economía mexicana. En la construcción de las funciones regionales de distribución del ingreso tipo Gauss-kernel se han empleado datos del Producto Interno Bruto per capita por entidad federativa, junto con las proporciones de ingreso por estrato poblacional. La desigualdad es un fenómeno persistente en las regiones de México. Sin embargo, aquellas regiones que han estado más expuestas a los procesos de apertura económica presentan menores niveles de desigualdad. Lo contrario sucede con el resto de las regiones en ese mismo arreglo.

El número de pacientes atendidos en los servicios de urgencias tras consumir cocaína y los casos de muerte secundarios al consumo de la misma han ido aumentando hasta multiplicarse por seis en los últimos años. El consumo de este alcaloide ocasiona efectos nocivos, constatados sobre diferentes órganos y sistemas corporales, e incluso la muerte. A nivel del SNC destaca, por su gravedad e incidencia, la patología cerebro-vascular hemorrágica (PCVH. Este tipo de cuadro se halla asociado al consumo de drogas ilícitas entre el 9,5% y el 34% de los accidentes vasculares en menores de 45 años, siendo la cocaína la más frecuentemente implicada en su presentación. Por otro lado, la rotura de un aneurisma o malformación arteriovenosa se ha detectado hasta en el 50% de los pacientes con PCVH secundarios al consumo de cocaína. Presentamos tres casos de muerte súbita en adultos por patología cerebro-vascular hemorrágica asociada al consumo de cocaína.Cocaine is the second most frequent illegal drug consumed in Spain after cannabis. A significant increase has occurred in the number of individuals treated in emergency departments after cocaine use just as in the number of cocaine-related deaths. These rates have been actually multiplied by six in the latest years. Cocaine causes injury in different organ systems, even death. In the CNS the use of cocaine is frequently associated with cerebral haemorrhage. Stroke in young adults below 45 years is usually related to drug use between 9,5% and 34% of cases, and cocaine is the most frequently mentioned drug. Otherwise, even 50% of cocaine-related stroke is the result of rupture of saccular aneurysms involving the arteries at the base of the brain and vascular malformation.

    1999-01-01

    Full Text Available En atención a que la vivienda y el agua potable, el alcantarillado, la electricidad, el gas combustible, la telefonía y la recolección domiciliaria de basuras son bienes complementarios, la legislación colombiana de Servicios Públicos Domiciliarios entiende por "usuario", y responsable legal por la factura, al propietario o arrendatario del inmueble que recibe los servicios, en tanto que denomina "consumidores" a la totalidad de ocupantes del predio. A diferencia de los restantes servicios, en el de aseo domiciliario a las viviendas no se realizan mediciones cotidianas a los residuos recogidos. La regulación reduce los costos de medición fijando promedios de producción mensual de basura por vivienda, de acuerdo con los cuales se fijan las tarifas. Las empresas han encontrado viviendas informales que albergan a varias familias lo cual conduce a interpretaciones encontradas sobre la correcta facturación del servicio. Este artículo examina las consecuencias de facturar el servicio según promedios, teniendo en cuenta dos fenómenos: el "equilibrio económico contractual" entre empresas y usuarios, y la distribución del ingreso en los seis estratos socioeconómicos establecidos en el Colombia. Concluye que el equilibrio no es alterado por ningún tipo de promedio, mientras que la distribución del ingreso entre estratos sí es afectada por el tipo de promedio utilizado en la facturación, y, en consecuencia, que si los municipios colombianos usaran el mejor promedio, el más adecuado a la estructura del mercado podrían mejorar la distribución del ingreso, sin originar "desequilibrios económicos" para las empresas prestadoras del servicio de aseo.

    Full Text Available Costa Rica destina el equivalente de algo más de un 20% de su PIB al financiamiento de una amplia gama de programas sociales públicos. Ese gasto social se financia principalmente con impuestos indirectos así como con las contribuciones específicas para la seguridad social. Cuando se considera el ingreso de mercado como referencia, solamente los impuestos directos resultan claramente progresivos, no así los impuestos indirectos ni las contribuciones a la seguridad social, que tienden a ser más neutrales en términos relativos. No obstante, la mayor parte de los programas sociales son progresivos, y algunos de ellos muy progresivos -especialmente los de transferencias monetarias, que son altamente focalizados-, lo cual resulta en reducciones en la pobreza y, principalmente, en la desigualdad. El estudio realizado hace evidente la enorme importancia de aumentar la magnitud y progresividad de los tributos, para darle sostenibilidad al gasto público social, así como fortalecer algunos programas focalizados que tienen un elevado impacto sobre los más pobres.

    Full Text Available En este trabajo se modela matemáticamente la visión de Leontief sobre La Estructura del Desarrollo (Leontief, 1963. El modelo se utiliza para examinar la relación de los países desarrollados y subdesarrollados en los mercados mundiales. Se concluye que bajo ciertas condiciones, específicamente relacionadas con la diferencia en la diversificación económica de los países, el exceso de oferta laboral de los países subdesarrollados y las restricciones a la movilidad internacional del trabajo, el modelo genera una brecha en el ingreso real per cápita de los países; en estas condiciones, el teorema de la igualación de precio de los factores deja de ser aplicable. El modelo permite sustentar la necesidad de políticas económicas que promuevan la diversificación económica de los países menos desarrollados.

    Full Text Available Un estudio a partir de los modelos de crecimiento kaleckianos. Cuadernos de Economía, 31(58, 23-47. El objetivo del presente artículo es analizar los mecanismos por medio de los cuales la demanda agregada y la distribución del ingreso determinan la tasa de crecimiento, en el marco de la teoría poskeynesiana inspirada por Michael Kalecki, contrariamente a lo que sugiere la teoría neoclásica, en la que el crecimiento solo depende de los factores asociados a la oferta. El rechazo de la ley de Say, sugerido por este tipo de modelos, permite mostrar el impacto que tiene la demanda sobre la tasa de crecimiento, dependiendo de la sensibilidad de las decisiones de ahorro e inversión ante modificaciones en el ingreso tanto de los trabajadores como de los capitalistas.

    Full Text Available En los últimos años, los regímenes actuales de movilidad urbana cotidiana y sus efectos sociales y medioambientales han sido materia de debate y preocupación pública. En el presente artículo pretendemos explorar el tema a través de un caso de estudio específico: el análisis de los motivos y percepciones detrás de la adquisición y el uso de automóviles por parte de habitantes de bajos ingresos de la ciudad de Santiago, Chile. En primer lugar veremos cómo puede ser entendido el automóvil y el tipo de movilidad urbana que genera desde una óptica de teoría social y urbana. En segundo lugar, presentaremos algunas tendencias generales de uso de automóviles en Santiago. Luego se analizarán en detalle los principales argumentos detrás de la adquisición, uso y valoración del automóvil por parte de un grupo de usuarios de bajos ingresos de la ciudad. Finalmente entregaremos, a partir de los análisis presentados, algunas ideas que pueden contribuir al diseño de políticas públicas que incentiven formas de movilidad urbana sustentables en la ciudad.In recent years, existingforms of daily urban mobility and their social and environmental impacts have become issues of debate and public concern. In this article we explore this issue through a specific case study: the analysis of the motives and perceptions that lie behind the acquisition and use of cars by low income residents in Santiago de Chile. Firstly we analyze how the car and the type of urban mobility that is generated are understood in terms of social and urban theory. Secondly, we present some general tendencies of car use in Santiago. Next we look in detail at the principal arguments behind acquisition, use and valuing of the vehicle by a group of low income users in the city. Finally, we offer, based on the analysis, some ideas that can contribute to the design of public policies that incentivize forms of sustainable urban mobility in the city.

    Full Text Available El presente artículo analiza la dinámica de las transformaciones acontecidas en los últimos años en la educación superior a distancia en América Latina y el Caribe y los ejes de crecimiento de la cobertura. Sobre  un enfoque comparado regional caracteriza sus diversas etapas e identifica su aporte a su expansión, con ciclos marcados por las tecnologías e impulsos públicos y privados y, ahora, internacionales. En este contexto se analiza la irrupción de una nueva fase de esta modalidad a distancia caracterizada por una dinámica internacionalizada. Se estudian las formas en las cuales se produce la internacionalización de la educación a distancia, que se realiza no dominantemente como educación transfronteriza sino como movilidad e ingreso de instituciones externas en los sistemas universitarios locales de los países de la región. La evolución de la educación a distancia muestra el continuo cambio desde el modelo semipresencial tradicional hacia una dinámica virtualizada, que al tiempo que introduce nuevas formas de funcionamiento, expande la cobertura y consolida instituciones con mayores escalas, y que también facilita dinámicas internacionales caracterizadas por la nueva presencia, por alianza y por compra, de nuevos proveedores internacionales.

    This paper reviews cranial MR findings in patients with cerebral palsy (CP) to clarify and categorize this disorder. The MR images of 40 patients with clinical CP were retrospectively reviewed. All patients suffered either varying spastic plegias, hypotonicity, or choreoathetosis. Concomitantly, the patients suffered from static encephalopathy, developmental delay, and/or microcephaly. Twenty-four patients were born at or near term, 10 were premature, and incomplete birth histories were available in six. The MR images revealed mild to severe degrees of white matter damage in 24 patients (12 term, nine premature, three unknown)

    Full Text Available Las investigaciones sobre los consumidores de bajos ingresos (CBI se han centrado en sus conductas y sólo excepcionalmente en las atribuciones de otros grupos dela sociedad acerca de estos consumidores. A pesar de las implicaciones que los rasgos atribuidos a estos sectores de la población puedan tener para modificar su condición, las investigaciones se han realizado en contextos donde este sector es minoritario y con muestras de escasa influencia política o económica. En este trabajo se presenta el desarrollode un instrumento para medir las atribuciones acerca de los CBI en una muestra políticamente relevante y su análisis psicométrico correspondiente. Se realizó un estudio decampo y se aplicó la escala a una muestra piloto elegida de manera intencional de 204 estudiantes de posgrado, elegidos intencionalmente según ocuparan posiciones de gerencia media en organizaciones que estuviesen llevando a cabo iniciativas de negocio dirigidas a CBI. La muestra final estuvo constituida por 370 estudiantes con las mismas características de los seleccionados para la prueba piloto. Elanálisis psicométrico revela una alta consistencia interna de la versión final del instrumento (Alfa= 0,89 y una solución factorial compuesta por dos dimensiones: sociabilidad y emprendimiento que fueron atribuidos en forma moderada a los CBI. Adicionalmente, se encontraron correlaciones significativas entre la edad y la dimensión sociabilidad de las atribuciones acerca de los CBI, entre el sexo y la dimensión emprendimiento, y entre las creencias individuales acerca de las causas de la pobreza y ambas dimensiones de las atribuciones acerca de los CBI.

    2013-01-01

    Malaria, the most significant parasitic disease of man, kills approximately one million people per year. Half of these deaths occur in those with cerebral malaria (CM). The World Health Organization (WHO) defines CM as an otherwise unexplained coma in a patient with malarial parasitemia. Worldwide, CM occurs primarily in African children and Asian adults, with the vast majority (greater than 90%) of cases occurring in children 5 years old or younger in sub-Saharan Africa. The pathophysiology of the disease is complex and involves infected erythrocyte sequestration, cerebral inflammation, and breakdown of the blood-brain barrier. A recently characterized malarial retinopathy is visual evidence of Plasmodium falciparum's pathophysiological processes occurring in the affected patient. Treatment consists of supportive care and antimalarial administration. Thus far, adjuvant therapies have not been shown to improve mortality rates or neurological outcomes in children with CM. For those who survive CM, residual neurological abnormalities are common. Epilepsy, cognitive impairment, behavioral disorders, and gross neurological deficits which include motor, sensory, and language impairments are frequent sequelae. Primary prevention strategies, including bed nets, vaccine development, and chemoprophylaxis, are in varied states of development and implementation. Continuing efforts to find successful primary prevention options and strategies to decrease neurological sequelae are needed. PMID:23829902

    International Nuclear Information System (INIS)

    Two cases of histologically proven cerebral cysticercosis are presented. In both cases subcutaneous tissue nodules, a rare feature, were present. Several disease patterns are apparent - meningeal, parenchymatous and ventricular, spinal cord lesions and mixed patterns. Epilepsy is by far the major presenting symptom of cysticercosis, which in turn plays a significant role in the causation of adult-onset epilepsy in Blacks. Despite its drawbacks, the haemag-glutination inhibition test remains the most satisfactory serological method at present available for the diagnosis of cysticercosis; it is positive in up to 85% of cases of proven cysticercosis. With the advent of computed tomography many cases of unsuspected cysticercosis (symptomatic or asymptomatic) are being discovered

    Full Text Available El artículo analiza la estructura de los gastos e ingresos de la Caja Real de Santafé, que fue la caja matriz del Virreinato de la Nueva Granada desde que fue fundado en 1739, y que cumplía una importante función en la articulación de los flujos de excedente fiscal entre las cajas superavitarias y deficitariasdurante el periodo colonial. El estallido de movimientos independentistas, autonomistas y realistas en varias regiones del Virreinato rápidamente produjo una crisis fiscal que implicó la transformación del mecanismo de financiación del gasto y la profundización de tendencias de crisis iniciadas en las últimas décadas del periodo colonial en algunos ramos específicos. El trabajo estudia la naturaleza de estas transformaciones comparando la estructura del gasto e ingreso de los últimos años de dominación colonial con la estructura que estos adquirieron en los años de la Primera República, entre 1811 y 1815. Como fuente, se utiliza material inédito derivado de la contabilidad de la Caja Real y de la Tesorería de Santafé, en particular los cortes y tanteos de cuentas producidos por la Caja Real entre 1803 y 1815.

    Full Text Available El ingreso reciente de la República Popular China a la Organización Mundial de Comercio (OMC ha causado revuelo a nivel internacional, tanto por el gran peso específico de esa nación, como por su rápida inserción en las corrientes mundiales de comercio. Existen diferencias reales y de percepción según el país: para Estados Unidos y la Unión Europea, aunque con enormes déficit comerciales frente a China, se les abren oportunidades en sectores anteriormente cerrados (agropecuario, telecomunicaciones, financiero. En cambio, México y otros exportadores de manufacturas de industria ligera temen la incursión creciente de los productos chinos en los mercados de naciones avanzadas, principalmente en el estadounidense. El avance de esta república se produjo antes de su ingreso a la OMC, así es que ahora, también para países como el nuestro, el camino es tratar de aprovechar mejor la creciente apertura del mercado de este territorio.

Se enmarca en una pregunta más amplia, que intenta relacionar la dinámica de las políticas de ayuda social, con las formas de construcción de ciudadanía y de subjetividad, en la relación Estado-sociedad civil en la realidad argentina. Analizar si las mismas contribuyen a la superación de la situación de pobreza, o se constituyen en estrategias de reproducción social de origen individual, consolidándose como un mecanismo de control social de la población. El análisis es el resultado de las primeras sistematizaciones, relevamientos bibliográficos y construcciones conceptuales en el contexo de una investigación doctoral. La hipótesis fue contrastada a partir del análisis de diferentes fuentes bibliográficas en diálogo con el marco teórico. Analizando el proceso de elaboración, diseño, gestión y administración, reflexionamos acerca del contexto en el que las medidas de política pública se insertan y la dinámica de la distribución y asignación de los fondos de ayuda social, arrojando luz sobre las transformaciones en la forma de ejercicio del poder. Mencionamos que la distribución de la ayuda social bajo la forma de planes de empleo y de sostenimiento de ingresos, no sólo ocupa un lugar preponderante en la agenda pública como un mecanismo de resolución de la cuestión del desempleo, sino que los programas y planes sociales se incorporan a la política estatal, también como mecanismos a través de los cuales se intenta resolver otros problemas que afectan la gobernabilidad y la reproducción del orden social capitalista. La distribución siguiendo criterios clientelares, permite un fortalecimiento de los grupos de base movilizados y la

    Cerebral microangiopathies are a very heterogenous group of diseases characterized by pathological changes of the small cerebral vessels. They account for 20 - 30 % of all ischemic strokes. Degenerative microangiopathy and sporadic cerebral amyloid angiography represent the typical acquired cerebral microangiopathies, which are found in over 90 % of cases. Besides, a wide variety of rare, hereditary microangiopathy exists, as e.g. CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), Fabrys disease and MELAS syndrome (Mitochondrial myopathy, Encephalopathy, Lactic Acidosis, and Stroke-like episodes).

    Full Text Available RESUMEN: El examen de las relaciones de rentas compiladas por los ministros de hacienda en momentos de crisis o dificultades financieras ofrece una buena imagen de la estructura y valor de los ingresos de la Corona de Castilla desde finales del siglo XVI y a lo largo del XVII. Gracias a estos documentos es posible medir el aumento de la carga tributaria durante la escalada fiscal del reinado de Felipe IV y la importancia de las medidas de alivio aprobadas en el de Carlos II, así como el peso de los ingresos estrictamente fiscales respecto a los extraordinarios. El artículo se detiene asimismo en el análisis de la evolución de la carga tributaria en términos «reales» planteando algunas de sus repercusiones sobre la economía y la población de Castilla.ABSTRACT: The study of a group of fiscal relations compiled by royal ministers in some moments of the XVIth and XVIIth centuries offers an accurate view of both the amount and the structure of the fiscal revenues collected by the Castilian Crown from 1577 to 1688. These documentary sources have allowed us to measure the increase of the tax burden during the reign of Philip IV and the importance of the measures subsequently adopted during the reign of Charles II to lighten such burden. Simultaneously, our sources have also allowed us to compare the amount and the evolution of the ordinary taxes collected by the Crown to that of the extraordinary incomes. To finish, our paper deals with the evolution of tax burden in real terms and its consequences on the Castilian economy and population.

El conocimiento de la fisiopatología de los diferentes tipos de parálisis cerebral bien como de las enfermedades asociadas y sus terapéuticas es imprescindible, pues permite al anestesista anticipar y precaver complicaciones intra y posoperatorias en este tipo de paciente.BACKGROUND AND OBJECTIVES: Cerebral palsy (CP is a non-progressive disease induced by CNS injury, which leads to patients' motor impairment. CP patients are often submitted to surgical procedures due to usual diseases and some surgical situations related with CP. The aim of this article was to review cerebral palsy aspects of interest to anesthesiologists to allow an adequate pre, intra and postoperative management of these patients. CONTENTS: This article addresses cerebral palsy aspects such as etiology, classification, risk factors, pathophysiology, clinical presentation, diagnosis and therapies and, in addition to preoperative evaluation, preanesthetic medication, intra and postoperative management, postoperative analgesia and chronic pain. CONCLUSIONS: Anesthesiologists play an important role in decreasing anesthetic-surgical morbidity and mortality of cerebral palsy patients. The understanding of different aspects of cerebral palsy pathophysiologies, in addition to those of associated diseases and their therapies is paramount, because it allows anesthesiologists to anticipate and prevent intra and postoperative complications in this type of patient.

Dos grandes grupos según su etiología se incluyen en esta categoría el hemorrágico que constituye un 20% y el isquémico en 80% de los casos. Gran interés ha ganado el ACA isquémico por su alta carga social, siendo la tercera causa de muerte no violenta a nivel mundial y la primera de discapacidad. Muchos factores de riesgo favorecen lapresentación de estos eventos y algunos de ellos son susceptibles de modificación y por tanto se constituyen en objetivos de prevención primaria tales como el control de la diabetes, hipertensión y la práctica de hábitos saludables de vida. Los avances en el conocimiento de la fisiopatología, han llevado a cambios sustanciales en la nomenclatura y manejo del ACA isquémico. Dentro de estos cambios se sustituyó el término accidente cerebrovascular por ataque cerebrovascular agudo, haciendo énfasis en la importancia de un manejo oportuno con metas de tiempo similar al sindrome coronario agudo. Se redefinió el tiempo de ataque isquémico transitorio a una hora. Una vez instaurado el evento cerebrovascular la semiología de los síntomas con frecuencia nos permitirá realizar un diagnóstico topográfico de la lesión, que

    Full Text Available La provisión de un bien privado por parte del sector público como política de redistribución del ingreso, es considerada una buena herramienta ante la falta de información sobre los agentes. No obstante, dicha política puede acarrear disyuntivas entre calidad y redistribución, y entre eficiencia y redistribución. Si se desea implementar esta clase de política, es preferible incurrir en un costo de información, una ineficiencia fija, para aplicar un impuesto progresivo y redistribuir el ingreso bajo el segundo teorema del bienestar, y no mediante una transferencia en especies. La política es más o menos efectiva dependiendo de las restricciones institucionales a las que se enfrente el Estado. Si dichas restricciones impiden la discriminación de acceso al sistema educativo, para que la política educativa tenga éxito es necesario olvidarse de la posibilidad de máxima redistribución. Lo anterior conllevara a que la política afianzara la diferencia entre los objetivos de calidad en la educación y, al mismo tiempo, enfrentar la inequidad.

  10. Cerebral angiography in leptomeningitis and cerebritis

    International Nuclear Information System (INIS)

    This is a report of the cerebral angiographic findings in cases of meningitis and cerebritis. Fifty-nine patients, 38 of whom were under 1 year of age, underwent cerebral angiography by means of femoral catheterization. All the patients had signs of increased intracranial pressure, seizures, focal cerebral signs, positive transillumination of the head, and or abnormal brain scan findings. A few patients who did not respond to systemic antibiotics as was expected were also evaluated by means of cerebral angiography. The following characteristic angiographic findings were observed in 18 cases of active meningitis: (1) A hasy appearance around the arteries (halo formation) between the late arterial and capillary phases. (2) Narrowing of the arteries in the basal cistern. This sometimes extended to the peripheral arteries. (3) Irregular caliber following the narrowing of arteries (in few cases). (4) Circulation time so slow that veins could be seen in the late arterial phase. (5) Halo formation around the anterior chroidal artery and the clear appearance of the choroid plexus in the venous phase (when the infectious process reached the choroid plexus). Cerebritis could be identified on the angiograms by two signs: (1) local swelling of the brain (mainly the temporal lobe) and (2) staining around the veins without any abnormal signs in the arterial phase (laminar staining). In conclusion, angiography is a meaningful test by which to determine the phase of meningitis and cerebritis. These two conditions should be treated based on valid information obtained by means of CSF examinations and neuroradiological tests, especially CT scan and cerebral angiography. (author)

    Full Text Available La insulina es una hormona con efectos sobre el metabolismo y crecimiento normal de muchas células del cuerpo. En las últimas décadas se han descubierto, además, sus efectos sobre funciones del sistema nervioso central: modulación del ciclo apetito-saciedad, función reproductiva, liberación de neurotransmisores, supervivencia neuronal y plasticidad sináptica. Las evidencias obtenidas desde modelos animales y hallazgos neuropatológicos han permitido entender parte de los mecanismos que asocian a la señal de la insulina con enfermedades neurodegenerativas como la enfermedad de Alzheimer. En este artículo se revisarán las acciones de la insulina sobre el hipotálamo, la supervivencia neuronal, la plasticidad sináptica y por último, las implicaciones de estos conocimientos en la comprensión de procesos degenerativos del sistema nervioso central como la enfermedad de Alzheimer.

    Full Text Available El propósito del presente trabajo es evaluar el efecto redistributivo de un sistema de tarifas sociales del agua potable, comparado con el actual modelo de subsidios estatales directos a la población de menores ingresos. Se busca determinar una asignación de precios sociales tal que permita una operación no deficitaria, usando un modelo matemático basado en conceptos de la economía del bienestar. Se evalúa un esquema de cobro diferenciado de la tarifa, según el ingreso de los clientes en la ciudad de Arica, Chile y su impacto teórico en la redistribución del ingreso en los consumidores. De los resultados de esta investigación se concluye que las tarifas sociales presentan una leve ventaja sobre los subsidios directos en términos redistributivos, sin embargo aparecen externalidades indeseables, que introducen distorsiones al mercado, las que podrían anular cualquier redistribución significativa.The purpose of this paper is to evaluate the redistributive effect of a system of social tariffs of water supply services, compared to the current direct subsidies from the government to low-income consumers. The goal is to determine social prices for non-deficit operation, using a mathematical model based on the theory of welfare economics. A scheme of differentiated tariffs according to income of consumers in the city of Arica, Chile, is evaluated as to the theoretical impact on the distribution of wealth of these consumers. From the results of this investigation, we concluded that social tariffs have a small advantage over direct subsidies in terms of redistribution, but undesirable side effects are produced, creating market distortions that could cancel out any significant redistribution of wealth.

    HMG-CoA reductase inhibitors (statins) are associated with improved stroke outcome. This observation has been attributed in part to the palliative effect of statins on cerebral hemodynamics and cerebral autoregulation (CA), which are mediated mainly through the upregulation of endothelium nitric oxide synthase (eNOS). Several animal studies indicate that statin pretreatment enhances cerebral blood flow after ischemic stroke, although this finding is not further supported in clinical settings. Cerebral vasomotor reactivity, however, is significantly improved after long-term statin administration in most patients with severe small vessel disease, aneurysmal subarachnoid hemorrhage, or impaired baseline CA.

En el Instituto Tecnológico de Durango, periódicamente se ha procesado la información relacionada con el examen de selección, comparándolo con el desempeño durante el primer semestre; sirviendo esto como base para la toma de decisiones de la calificación de corte para la aceptación o el rechazo y a los resultados que proporcionan mayor certidumbre para las decisiones. La automatización de este procedimiento plantea la necesidad de que en el departamento encargado, se cuente con personal con formación en el área de informática y, con equipo para el procesamiento de la información. Una vez dadas las condiciones antes mencionadas, en el Departamento de Desarrollo Académico se emprendió el proceso de automatización de la determinación de la validez del examen de selección mediante el método de exactitud en la toma de decisiones, habiendo utilizado como criterio el desempeño académico de los alumnos durante el primer semestre. Hasta el momento, se cuenta con los resultados de los alumnos aceptados en agosto de 1997 correspondientes al primero, segundo y tercer semestre; con ello, se plantea ahora la posibilidad de hacer un seguimiento de las generaciones; utilizando esta metodología, para establecer la validez de los exámenes de selección utilizando como criterios los resultados obtenidos en cada uno de los semestres, hasta llegar a determinar su validez con respecto a la finalización o no de la carrera.

El deterioro funcional se redujo solo cuando incluía una valoración multidimensional y examen clínico inicial [OR 0,64 (0,48-0,87]. Solo existió una disminución de la mortalidad en los adultos mayores 77 años que recibían visitas domiciliarias [OR 0,74 (0,58 a 0,94]. Comentario: el estudio presenta suficiente validez, la estrategia de búsqueda fue amplia y completa, sin restricción de idioma e incluyó literatura gris. Fue evaluada la calidad de los estudios considerando la randomización, ocultamiento de la secuencia y ciego. Para valorar la heterogeneidad se utilizó un indicador de medición de inconsistencia y el valor p.

    2001-01-01

    Full Text Available En la primera etapa de la Guerra de Independencia, la real caja de México mostró una caída importante en los ingresos fiscales. Esto fue el resultado de la decisión de los oficiales reales de otras tesorerías de no enviar sus excedentes a la capital del virreinato, y por la desorganización que en esos años experimentara la administración fiscal del virreinato. El presente artículo proporciona una explicación neoinstitucional a la caída de los ingresos reales. Su principal conclusión es que, debido a un cambio en precios relativos, provocado por la guerra, se hizo atractivo para los habitantes de las provincias dejar de remitir a la ciudad de México sus excedentes fiscales.

    We evaluated six children in whom MR imaging showed unilateral cerebral polymicrogyria associated with ipsilateral cerebral atrophy and ipsilateral brain stem atrophy. The aim of this study was to clarify whether this disorder based on neuroimaging constitutes a new homogeneous clinical entity. The subjects were six children whose ages at the time of MR imaging ranged from 8 months to 11 years. Their clinical and MR features were analyzed. All of the children were born between 38 and 42 weeks gestation, without any significant perinatal events. Spastic hemiplegia and epilepsy were observed in all of the patients, and mental retardation was observed in four. The MR findings included unilateral cerebral polymicrogyria associated with ipsilateral cerebral hemiatrophy and ipsilateral brain stem atrophy in all patients. The ipsilateral sylvian fissure was hypoplastic in four patients. These patients showed relatively homogeneous clinical and neuroimaging features. Although the additional clinical features varied according to the site and the extent affected by the polymicrogyria, this disorder could constitute a new relatively homogeneous clinical entity.

Este giro tiene como telón de fondo el tránsito del monopolio estatal de ambas bebidas al ámbito privado y la defensa que los pueblos de indios hicieron de su consumo, en un momento de transición social y económica hacia el Estado agroexportador cafetalero.Between the years 1840-1865, the Guatemalan Government approach concerning the consumption of alcoholic beverages changed from a perspective in which public morality was predominant to one in which the need of maximizing tax revenues from the manufacture and sale of hard liquor and chicha prevailed over. This shift has as background the change from the State monopoly to the private monopoly and the defense that indigenous towns made of the alcoholic beverages consumption, at a time of social and economic transition to the coffee-producing State.

    Introducción: la otitis media aguda es una inflamación del oído medio frecuente en la edad pediátrica. Aproximadamente 2 % de todos los casos desarrolla complicaciones intracraneales, más específicamente meningitis; por lo general, los infartos cerebrales originados por esta última son venosos. Rara vez se ha descrito la ocurrencia de un infarto arterial cerebral como complicación directa de la otitis media aguda. Caso clínico: niña de 12 meses de edad quien fue llevada a un servicio de urgencias por síndrome febril secundario a otitis media aguda y alteración del estado de conciencia. A la exploración física se identificó que estaba somnolienta, con anisocoria, midriasis en el ojo derecho y hemiparesia izquierda. Con la tomografía axial computarizada de cerebro se apreció un infarto arterial cerebral extenso. Los padres no autorizaron la craniectomía descompresiva y la paciente falleció a las 48 horas de su ingreso hospitalario. Conclusiones: a pesar de los recursos tecnológicos con los que se dispone actualmente, el infarto cerebral relacionado con la otitis media aguda tiene una evolución tórpida. Los signos neurológicos focalizadores y el deterioro progresivo deben apuntar a la ineficacia del tratamiento antimicrobiano instaurado.

Injury to the developing brain that occurs either in utero or soon after birth can result in the motor, sensory, and cognitive deficits seen in cerebral palsy. Although the etiologies for cerebral palsy are variable, neuroinflammation plays a key role in the pathophysiology of the brain injury irrespective of the etiology. Currently, there is no effective cure for cerebral palsy. Nanomedicine offers a new frontier in the development of therapies for prevention and treatment of brain injury resulting in cerebral palsy. Nanomaterials such as dendrimers provide opportunities for the targeted delivery of multiple drugs that can mitigate several pathways involved in injury and can be delivered specifically to the cells that are responsible for neuroinflammation and injury. These materials also offer the opportunity to deliver agents that would promote repair and regeneration in the brain, resulting not only in attenuation of injury, but also enabling normal growth. In this review, the current advances in nanotechnology for treatment of brain injury are discussed with specific relevance to cerebral palsy. Future directions that would facilitate clinical translation in neonates and children are also addressed.

    Notice points in clinical imaging of cerebral ischemia are reviewed. When cerebral blood flow is determined in acute stage of cerebral embolism (cerebral blood flow SPECT), it is important to find area of ischemic core and ischemic penumbra. When large cortex area is assigned to ischemic penumbra, thrombolytic therapy is positively adapted, but cautious correspondence is necessary when ischemic core is recognized. DWI is superior in the detection of area equivalent to ischemic core of early stage, but, in imaging of area equivalent to ischemic penumbra, perfusion image or distribution image of cerebral blood volume (CBV) by MRI need to be combined. Luxury perfusion detected by cerebral blood flow SPECT in the cases of acute cerebral embolism suggests vascular recanalization, but a comparison with CT/MRI and continuous assessment of cerebral circulation dynamics were necessary in order to predict brain tissue disease (metabolic abnormality). In hemodynamic cerebral ischemia, it is important to find stage 2 equivalent to misery perfusion by quantification of cerebral blood flow SPECT. Degree of diaschisis can indicate seriousness of brain dysfunction for lacuna infarct. Because cerebral circulation reserve ability (perfusion pressure) is normal in all areas of the low cerebral blood flow by diaschisis mechanism, their areas are easily distinguished from those of hemodynamic cerebral ischemia.

    Clinical and angiographic findings in migraine are briefly reviewed in relation to cerebral hemodynamic changes shown by regional cerebral blood flow (rCBF) studies. Three cases of migraine studied by the intracarotid xenon 133 method during attacks are reported. In classic migraine, with typical...... prodromal symptoms, a decrease in cerebral blood flow has been demonstrated during the aura. Occasionally, this flow decrease persists during the headache phase. In common migraine, where such prodromata are not seen, a flow decrease has not been demonstrated. During the headache phase of both types...... of migraine, rCBF has usually been found to be normal or in the high range of normal values. The high values may represent postischemic hyperemia, but are probably more frequently secondary to arousal caused by pain. Thus, during the headache phase rCBF may be subnormal, normal or high. These findings do...

  4. Cerebral fat embolism

    International Nuclear Information System (INIS)

    A case of cerebral fat embolism is reported. A 18-year-old patient with multiple bone fractures was in semiconma immediately after an injury. Brain CT showed no brain swelling or intracranial hematoma. Hypoxemia and alcoholemia were noted on admission, which returned to normal without improvement of consciousness level. In addition, respiratory symptoms with positive radiographic changes, tachycardia, pyrexia, sudden drop in hemoglobin level, and sudden thrombocytopenia developed. These symptoms were compatible with Gurd's criteria of systemic fat embolism. Eight days after injury, multiple low density areas appeared on CT and disappeared within the subsequent two weeks, and subdural effusion with cerebral atrophy developed. These CT findings were not considered due to cerebral trauma. Diagnosis of cerebral fat embolism was made. The subdural effusion was drained. Neurologic and pulmonary recoveries took place slowly and one month following the injury the patient became alert and exhibited fully coordinated limb movement. The CT scans of the present case well corresponded with hitherto reported pathological findings. Petechiae in the white matter must have developed on the day of injury, which could not be detected by CT examination. It is suggested that some petechial regions fused to purpuras and then gradually resolved when they were detected as multiple low density areas on CT. CT in the purpuras phase would have shown these lesions as high density areas. These lesions must have healed with formation of tiny scars and blood pigment which were demonstrated as the disappearance of multiple low density areas by CT examination. Cerebral atrophy and subsequent subdural effusion developed as a result of demyelination. The patient took the typical clinical course of cerebral fat embolism and serial CT scans served for its assessment. (author)

Este análisis se hace a partir de casos de estudio individuales. La investigación se basa en un marco teórico interdisciplinar y en datos empíricos recogidos en Concepción, Chile· Los resultados sugieren la existencia de un espacio de actividades delimitado por los lugares donde los individuos desarrollan sus actividades sociales cotidianas, su entorno cercano. A ello se suma el espacio de movimiento que se conforma por la ruta o trayecto entre el hogar y trabajo de los individuos, y los lugares de interacción social con sus redes personales. Los análisis revelan la dualidad existente entre el espacio de actividades de sectores de ingresos altos y el de sectores de bajos ingresos, sugiriendo que la integración socioespacial y problemas concomitantes tiene ribetes más complejos y multidimensionales que los generalmente abordados en la literatura.

Con la base de datos de la Encuesta nacional de ocupación y empleo de 2006, se calculó un escenario contrafactual con la asunción de lo que pasaría con la distribución de los salarios si los informales se desempeñaran como empleados formales. Los resultados indican que los informales asalariados y por cuenta propia están en mejor situación, y es menos favorable la expectativa para los segundos en Sonora, así como para los jornaleros agrícolas en ambos lugares. Los informales por cuenta propia no cambian sustancialmente sus ingresos, si se ubican en la parte alta de la distribución en Sonora, y hay una polarización de las percepciones en los asalariados en la frontera.

  12. Recurrent cerebral thrombosis

    International Nuclear Information System (INIS)

    Neuroradiological techniques were used to elucidate pathophysiology of recurrent cerebral thrombosis. Twenty-two patients with cerebral thrombosis who suffered a second attack under stable conditions more than 22 days after the initial stroke were studied. Hypertension, diabetes mellitus, and hypercholesterolemia were also seen in 20, 8, and 12 patients, respectively. The patients were divided into three groups according to their symptoms: (I) symptoms differed between the first and second strokes (n=12); (II) initial symptoms were suddenly deteriorated (n=6); and (III) symptoms occurring in groups I and II were seen (n=4). In group I, contralateral hemiparesis or suprabulbar palsy was often associated with the initial hemiparesis. The time of recurrent stroke varied from 4 months to 9 years. CT and MRI showed not only lacunae in both hemispheres, but also deep white-matter ischemia of the centrum semi-ovale. In group II, hemiparesis or visual field defect was deteriorated early after the initial stroke. In addition, neuroimaging revealed that infarction in the posterior cerebral artery was progressed on the contralateral side, or that white matter lesion in the middle artery was enlarged in spite of small lesion in the left cerebral hemisphere. All patients in group III had deterioration of right hemiparesis associated with aphasia. CT, MRI, SPECT, and angiography indicated deep white-matter ischemia caused by main trunk lesions in the left hemisphere. Group III seemed to be equivalent to group II, except for laterality of the lesion. Neuroradiological assessment of the initial stroke may help to predict the mode of recurrence, although pathophysiology of cerebral thrombosis is complicated and varies from patient to patient.

El objetivo de este estudio fue evaluar el midazolam como medicación preanestésica en el BIS de los pacientes con PC en uso crónico de antiepilépticos. MÉTODO: Se evaluaron tres grupos de pacientes: PC sin uso de antiepilépticos, PC en uso de antiepiléptico y otro grupo sin enfermedad y sin uso de medicaciones (grupo control. En la víspera de la cirugía, con los pacientes despiertos y en decúbito dorsal, fue colocado el monitor del BIS y se registraron los valores basales del BIS. Al día siguiente, 40 minutos antes de la cirugía, los pacientes recibieron 0,6 mg.kg-1 de midazolam por vía oral. Antes del inicio de la anestesia fue realizado el mismo procedimiento para registro del BIS, después del uso del midazolam. RESULTADOS: Fueron estudiados 107 pacientes, 39 pacientes del grupo control y 68 con diagnóstico de PC. De ellos, 17 usaban antiepilépticos. Con relación al valor promedio de BIS después del uso del midazolam, no hubo diferencia entres los pacientes del grupo control y del grupo PC que no tomaban antiepiléptico, mientras que los pacientes que usaban antiepilépticos fueron diferentes (p = 0,003. La posibilidad de disminución del BIS después del uso del midazolam, aumenta de acuerdo con el número de antiepiléptico usado por el paciente. CONCLUSIONES: El uso crónico de antiepiléptico asociado al midazolam vía oral como medicación preanestésica, puede conllevar a la disminución de los valores de BIS configurando niveles profundos de hipnosis.BACKGROUND AND OBJECTIVES: Patients with cerebral palsy (CP frequently receive drugs for the treatment of concomitant diseases, such as seizures.

Estos síndromes se caracterizan por tener una sintomatología común: los trastornos motores. Algunos autores prefieren manejar términos como "encefalopatía fija", "encefalopatías no evolutivas". Se mencionan la utilidad de programas de intervención temprana y métodos especiales de rehabilitación, así como el manejo de las deficiencias asociadas como la epilepsia, deficiencia mental, trastornos del lenguaje, audición, visión, déficit de la atención que mejoran el pronóstico de manera significativa. El pronóstico también depende de la gravedad del padecimiento y de las manifestaciones asociadas.The term cerebral palsy (CP, is used for a great number of clinical neurological syndromes. The syndromes are characterized by having a common cause, motor defects. It is important, because they can cause a brain damage by presenting motor defects and some associated deficiencies, such as mental deficiency, epilepsy, language and visual defects and pseudobulbar paralysis, with the nonevolving fact. Some authors prefer using terms such as "non-evolving encephalopathies". In the treatment the utility of prevention programs of early stimulation and special rehabilitation methods, and treatment of associated deficiencies such as epilepsy, mental deficiency, language, audition and visual problems, and the attention deficit improve the prognosis in an important way. The prognosis depends on the severity of the disease and the associated manifestations.

    Fragments of neurology can be found in the oldest medical writings in antiquity. Recognizable cerebral localization is seen in Egyptian medical papyri. Most notably, the Edwin Smith papyrus describes hemiplegia after a head injury. Similar echoes can be seen in Homer, the Bible, and the pre-Hippocratic writer Alcmaeon of Croton. While Biblical writers thought that the heart was the seat of the soul, Hippocratic writers located it in the head. Alexandrian anatomists described the nerves, and Galen developed the ventricular theory of cognition whereby mental functions are classified and localized in one of the cerebral ventricles. Medieval scholars, including the early Church Fathers, modified Galenic ventricular theory so as to make it a dynamic model of cognition. Physicians in antiquity subdivided the brain into separate areas and attributed to them different functions, a phenomenon that connects them with modern neurologists. PMID:20183203

    Previous studies performed by positron emission tomography and Transcranial Doppler (TCD) found a different cerebral activation during musical stimuli in musicians compared to non-musicians. The aim of our study is to evaluate by means of TCD, possible different pattern of cerebral activation during the performance of different musical tasks in musicians, non-musicians and lyrical singers. Our findings show a left hemispheric activation in musicians and a right one in non-musicians. Preliminary data on lyrical singers' activation patterns need further confirmation with a larger population. These data could be related to a different approach to music listening in musicians (analytical) and non-musicians who are supposed to have an emotional approach to music. PMID:10942664

    Computerized tomography, carotid angiograms, and arteriography were used to diagnose several cases of cerebral hemorrhage following the use of phenylpropanolamine. The angiographic picture in one of the three cases was similar to that previously described in association with amphetamine abuse and pseudoephedrine overdose, both substances being chemically and pharmacologically similar to phenylpropanolamine. The study suggests that the arterial change responsible for symptoms may be due to spasm rather than arteriopathy. 14 references, 5 figures.

  4. Phenylpropanolamine and cerebral hemorrhage

    International Nuclear Information System (INIS)

    Computerized tomography, carotid angiograms, and arteriography were used to diagnose several cases of cerebral hemorrhage following the use of phenylpropanolamine. The angiographic picture in one of the three cases was similar to that previously described in association with amphetamine abuse and pseudoephedrine overdose, both substances being chemically and pharmacologically similar to phenylpropanolamine. The study suggests that the arterial change responsible for symptoms may be due to spasm rather than arteriopathy. 14 references, 5 figures

    Insomnia is defined as difficulty with the initiation, maintenance, duration, or quality of sleep that results in the impairment of daytime functioning, despite adequate opportunity and circumstances for sleep. In most countries approximately every third inhabitant has insomnia. Insomnia can be classified as primary and secondary. The pathogenesis of primary insomnia is unknown, but available evidence suggests a state of hyperarousal. Insomnia secondary to other causes is more common than primary insomnia. Cerebral hypoperfusion can be the cause of insomnia in some cases. In such patients the cerebral blood flow should be improved using parenteral vascular therapy. If insomnia persists despite treatment, then therapy for primary insomnia should be instituted using benzodiazepine-receptor agonists such as Zolpidem, Zopiclone, or Zaleplon. In those cases Midazolam cannot be used for the treatment of insomnia due to its marked negative effect on cerebral blood flow. In Hungary there is a need to organize multidisciplinary Insomnia Clinics because insomnia is more than a disease, it is a public health problem in this century. PMID:17988972

  6. Cerebral oxygenation and hyperthermia

    Directory of Open Access Journals (Sweden)

    Full Text Available Hyperthermia is associated with marked reductions in cerebral blood flow (CBF. Increased distribution of cardiac output to the periphery, increases in alveolar ventilation and resultant hypocapnia each contribute to the fall in CBF during passive hyperthermia; however, their relative contribution remains a point of contention, and probably depends on the experimental condition (e.g. posture and degree of hyperthermia. The hyperthermia-induced hyperventilatory response reduces arterial CO2 pressure (PaCO2 causing cerebral vasoconstriction and subsequent reductions in flow. During supine passive hyperthermia, the majority of recent data indicate that reductions in PaCO2 may be the primary, if not sole, culprit for reduced CBF. On the other hand, during more dynamic conditions (e.g. hemorrhage or orthostatic challenges, an inability to appropriately decrease peripheral vascular conductance presents a condition whereby adequate cerebral perfusion pressure may be compromised secondary to reductions in systemic blood pressure. Although studies have reported maintenance of pre-frontal cortex oxygenation (assessed by near-infrared spectroscopy during exercise and severe heat stress, the influence of cutaneous blood flow is known to contaminate this measure. This review discusses the governing mechanisms associated with changes in CBF and oxygenation during moderate to severe (i.e. 1.0°C to 2.0°C increase in body core temperature levels of hyperthermia. Future research directions are provided.

    Cerebral malformations are usually described following the different steps in development. Disorders of neurulation (dysraphisms), or diverticulation (holoprosencephalies and posterior fossa cysts), and total commissural agenesis are usually diagnosed in utero. In contrast, disorders of histogenesis (proliferation-differentiation, migration, organization) are usually discovered in infants and children. The principal clinical symptoms that may be a clue to cerebral malformation include congenital hemiparesis, epilepsy and mental or psychomotor retardation. MRI is the imaging method of choice to assess cerebral malformations. (orig.)

    Full Text Available Este artículo presenta una base de datos recién compilada y mejorada de encuestas nacionales de hogares entre 1988 y 2008. En 2008, el índice global de Gini es de un 70,5% después de disminuir en cerca de 2 puntos Gini en este periodo. Cuando se ajusta por el probable subregistro de los ingresos superiores de las encuestas usando la brecha entre el consumo de cuentas nacionales y el promedio de las encuestas junto con una imputación tipo Pareto de la cola superior, resulta un Gini global mucho más alto de casi un 76%. Con tal ajuste la tendencia decreciente del Gini casi desaparece. El seguimiento de la evolución de los deciles-país individuales muestra los elementos subyacentes que impulsan los cambios en la distribución global: China salió de los rangos más bajos, en el proceso se modificó la forma total de la distribución global del ingreso y se creó una importante clase “mediana” global que transformó la distribución de dos picos de 1988 en una de un pico. Los “ganadores” fueron los deciles-país que en 1988 estaba alrededor de la mediana de la distribución global, el 90% de los cuales, en términos de población, son de Asia. Los “perdedores” fueron los deciles-país que en 1988 estaban alrededor del percentil 85 de la distribución global, casi el 90% de los cuales, en términos de población, son de economías maduras.

    2005-11-01

    Various therapeutic interventions have been used in the management of children with cerebral palsy. Traditional physiotherapy and occupational therapy are widely used interventions and have been shown to be of benefit in the treatment of cerebral palsy. Evidence in support of the effectiveness of the neurodevelopmental treatment is equivocal at best. There is evidence to support the use and effectiveness of neuromuscular electrical stimulation in children with cerebral palsy. The effectiveness of many other interventions used in the treatment of cerebral palsy has not been clearly established based on well-controlled trials. These include: sensory integration, body-weight support treadmill training, conductive education, constraint-induced therapy, hyperbaric oxygen therapy, and the Vojta method. This article provides an overview of salient aspects of popular interventions used in the management of children with cerebral palsy. PMID:16391455

  19. Cerebral hemodynamics in moyamoya disease

    International Nuclear Information System (INIS)

    Rebuild-up phenomenon, an electroencephalographic pathological finding in moyamoya disease, was evaluated in the context of dynamic changes in cerebral circulation after hyperventilation. Sequential functional angiography after hyperventilation, measurement of cerebral blood flow (CBF) by the outflow method, and Kr-81m single photon emission tomography were employed for clarification of the sequential dynamic changes in cerebral circulation after hyperventilation. In most cases there was a persistent decrease in CBF even after arterial carbon dioxide tension (PaCO2) had been normalized, which suggests that the response of the cerebral circulation to the changes in PaCO2 is delayed. Moreover, this feature was most prominent in the superficial layer of the cerebrum. For the most part, coincidence and synchronization were documented between rebuild-up and the delayed response of the cerebral circulation. These findings indicate that the delayed CBF response to hyperventilation contributes pathogenetically to rebuild-up in moyamoya disease. (author)

Presentamos el caso de una niña diagnosticada de TGV con SI a los 5 meses y 15 días de edad. Se intervino mediante atriseptostomía de urgencia y posterior cirugía de "recuperación" (banding de la arteria pulmonar y shunt subclavia-pulmonar previa a la corrección anatómica mediante switch arterial. Falleció a los 8 días del ingreso como consecuencia de un infarto cerebral isquémico.Transposition of the Great Arteries (TGA with intact ventricular septum is a congenital heart disease characterized by ventricle-arterial discordance and atria-ventricle concordance. Cyanosis is common in patients with TGA because there is no mixing between systemic and pulmonary circulations through a ventricular septal defect and systemic oxygenation is not possible. We report the case of a 5 months and 15 days old female infant who was diagnosed with TGA with intact septum. Balloon atrial septostomy and "retraining" of left ventricle by pulmonary artery banding and subclavian-pulmonary artery shunt were necessary to be performed before anatomical correction by arterial switch. Nevertheless, she died 8 days after admission due to an ischemic stroke.

  1. Cerebral imaging in pediatrics

    International Nuclear Information System (INIS)

    Radioisotope brain imaging has focused mainly on regional cerebral blood flow (rCBF). However the use of ligand which go to specific receptor sites is being introduced in pediatrics, mainly psychiatry. rCBF is potentially available in many institutions, especially with the availability of multi-headed gamma cameras. The use of this technique in pediatrics requires special attention to detail in the manner of data acquisition and handling the child. The interpretation of the rCBF study in a child requires knowledge of normal brain maturation. The major clinical use in pediatrics is epilepsy because of the advances in surgery and the frequency of complex partial seizures. Other indications in pediatric neurology include brain death, acute neurological loss including stroke, language disorders, cerebral palsy, hypertension due to renovascular disease, traumatic brain injury and migraine. There are pediatric physiological conditions in which rCBF has been undertaken, these include anorexia nervosa, autism, Gilles de la Tourette syndrome (GTS) and attention deficit disorder-hyperactivity (ADHD).

    Cerebral cartography and connectomics pursue similar goals in attempting to create maps that can inform our understanding of the structural and functional organization of the cortex. Connectome maps explicitly aim at representing the brain as a complex network, a collection of nodes and their interconnecting edges. This article reflects on some of the challenges that currently arise in the intersection of cerebral cartography and connectomics. Principal challenges concern the temporal dynamics of functional brain connectivity, the definition of areal parcellations and their hierarchical organization into large-scale networks, the extension of whole-brain connectivity to cellular-scale networks, and the mapping of structure/function relations in empirical recordings and computational models. Successfully addressing these challenges will require extensions of methods and tools from network science to the mapping and analysis of human brain connectivity data. The emerging view that the brain is more than a collection of areas, but is fundamentally operating as a complex networked system, will continue to drive the creation of ever more detailed and multi-modal network maps as tools for on-going exploration and discovery in human connectomics.

    Full Text Available Cerebral sinus venous thrombosis (CSVT is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment.

    Computed tomography (CT) was performed on 200 children with cerebral palsy with Hitachi CT-H250. The CT scans of 136 cases revealed cerebral atrophy with ventricular and/or subarachnoid space enlargement. The lateral ventricles, the third ventricle and the two parts of subarachnoid space on the CT picture were subjectively evaluated and divided into five grades ranging from no enlargement to marked enlargement. In addition, the size of the ventricles and the subarachnoid spaces were quantitatively determined; the transverse diameter of brain (b), the largest width of the anterior horns of the lateral ventricles (c), the bicaudate nuclear distance (d), the greatest width of the third ventricle, the longitudinal cerebral fissure and sylvian fissures as described by Miyao et al. (1978). Comparison of these quantitative techniques confirmed the initial subjective evaluation. However, in some cases, amendment of the subjective evaluation was needed. As mentioned before (Miyao et al.), the cerebral longitudinal fissure was relatively wide in normal infants. Accordingly, it was often difficult to find out abnormal widening only by subjective evaluation. The purpose of this paper was to establish the criteria of quantitative measuring and assessing of the lateral and third ventricles, the cerebral longitudinal fissures, and the sylvian fissures enlargement. Interpretation of some problem cases associated with measuring was also discussed. The quantitative CT evaluation may be a good reference in assessing cerebral atrophy in cerebral palsy and other neurological diseases.

Music is one of the best means of expressing oneself and plays a very important role in the development of every child, the child with cerebral palsy in particular.In order to test the possibility of pupils with cerebral palsy, with and without mental retardation, to apprehend the actual program content, we have conducted research on musical achievement of children with cerebral palsy. During 2007 a research was carried out, on the sample of 27 pupils with cerebral palsy and mild mental retardation who attended classes in the school “Miodrag Matikj”, and a sample of16 students with cerebral palsy without mental retardation who attended the school “Dr. Dragan Hercog” in Belgrade.Results of the research, as well as analysis of music curriculum content, indicated that the capacities of students with cerebral palsy to carry out the curriculum tasks require special approach and methodology. Therefore, we introduced some proposals to overcome the difficulties in fulfilling music curriculum demands of those pupils. We made special emphasis on the use of computer based Assistive technology which facilitates the whole process to a large extent.

    Full Text Available INTRODUCTION: Cerebral palsy (CP is a group of permanent movement disorders that appear in early childhood. Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. Most often the problems occur during pregnancy; however, they may also occur during childbirth, or shortly after birth. Often the cause is unknown. AIM: To study the different antenatal maternal risk factors associated with cerebral palsy in the study group. MATERIA LS AND METHODS: Retrospective study was done to assess possible associated antenatal risk factors for cerebral palsy. Mothers of 100 cerebral palsy children were selected who are treated in Rani Chandramani Devi Hospital, a Government hospital in Visakhapa tn am, Andhra Pradesh State, India , from 2012 to 2014 and 100 controls, mothers of normal children were studied. Detailed antenatal history was obtained from the mothers of the children in both affected and control group. RESULTS: From the data, we conclude that the association of maternal anaemia with cerebral palsy is 7.3 times higher; association of maternal hypertension with cerebral palsy is 6.6 time higher, association with Pre - eclampsia is 6 times higher; association with Eclampsia is 8.6 times higher ; with antepartum haemorrhage, the association is 8.6 times higher and association of multiple pregnancy with cerebral palsy is 4.8 times higher than with controls. CONCLUSION: From this study of the role of antenatal risk factors, in the occurrence of cer ebral palsy in children it is concluded that the most common risk factor associated with cerebral palsy is the maternal anaemia and the other important risk factors associated being hypertension, pre eclampsia, eclampsia, antepartum haemorrhage and multipl e births.

    Full Text Available Desde tiempos tan lejanos como los de Adam Smith, los economistas pusieron énfasis en el entorno social como un elemento clave para explicar el comportamiento delictivo. Sin embargo, el análisis empírico no siempre confirmó esta conjetura. Partiendo del marco teórico propuesto por Becker (1968, el presente trabajo identifica mediante un análisis econométrico de datos de panel para el período 1990-97, los determinantes de la tasa de delincuencia argentina. Al igual que en otros trabajos que estudian el caso argentino, encontramos que existe un efecto disuasión. Sin embargo, a diferencia de éstos, encontramos que existe un efecto de entorno social sobre la tasa de delincuencia, con importantes implicancias para el diseño de políticas destinadas a combatir la delincuencia.

    Since 1982 (Hauser and co-workers), literature has reported focal cerebral tissue charges in AIDS patients whose diagnosis was unclear at first but which could be identified finally as florid toxoplasmosis encephalitis by biopsy and autopsy. It was found that the value of otherwise reliable serological tests (KBR, Sabin-Feldmann tests, etc.) is questionable in patients with severely impaired or incompetent immune systems, and, in particular, that a negative or uncharacteristic test result may not preclude any opportunistic infection process. Furthermore, isolation of Toxoplasma gondii or specific antibodies from the cerebrospinal fluid will be successful in exceptional cases only. In patients with AIDS or lymphadenopathy syndrome, the differential diagnosis will have to include - first and foremost - reactivated toxoplasma infection (not newly acquired, as a rule) if central neurological symptoms occur.

  16. Cerebral white matter hypoplasia

    International Nuclear Information System (INIS)

    This paper demonstrates the MR imaging findings in children with cerebral white matter hypoplasia (CWMH). The MR studies of four children, aged 3-7 y (mean age, 2.3 y) with a diagnosis of CWMH were reviewed. In all cases multiplanar T1-weighted and T2-weighted spin-echo images were obtained. All children had similar histories of severe developmental delay and nonprogressive neurologic deficits despite normal gestational and birth histories. In two cases there was a history of maternal cocaine abuse. Autopsy correlation was available in one child. The MR images of all four children demonstrated diffuse lack of white matter and enlarged ventricles but normal-appearing gray matter. The corpus callosum, although completely formed, was severely thinned. There was no evidence of gliosis or porencephaly, and the distribution of myelin deposition was normal for age in all cases. Autopsy finding in one child correlated exactly with the MR finding

    Treatment of cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH) remains a major therapeutic challenge. Systemic drug administration is the current treatment of choice, but patients often do not respond beneficially to this approach. Intrathecal (IT) drug administration has several anatomic and pharmacodynamic advantages over conventional systemic treatment of cerebral vasospasm. We reviewed the most recent literature describing IT administration of several drugs to treat aneurysm-induced SAH and cerebral vasospasm, including 16 clinical trials using IT fibrinolytic agents and 10 trials using several IT vasodilators. We evaluated the safety and effectiveness of these trials but made no attempt to perform a meta-analysis using these data. IT drug administration of fibrinolytic agents and vasodilators caused lysis of the subarachnoid clot burden and diminished cerebral vasospasm, respectively. The studies reviewed reported a wide range of drug doses, intervals between aneurysm hemorrhage and initiation of treatment, success of clot dissolution, and degree of vasodilation of vessels in vasospasm. Treatment of vasospasm by IT drug administration is safe and largely effective after the aneurysm has been secured. Our findings indicate that IT treatment effectively delivers a higher drug concentration to vessels in vasospasm with minimal systemic effects. Drugs administered by this route are reported to lyse subarachnoid clots, attenuate cerebral vasospasm, improve clinical outcomes, and decrease the incidence of hydrocephalus. With greater understanding of drug pharmacodynamics, the IT route of drug administration may provide a rational, alternative approach to treating aneurysm-induced cerebral vasospasm. PMID:22651990

Entre ellas se encuentra, el Worker Profiling and Reemployment Services System que encuentra su fundamento en la necesidad de reducir la dependencia de los individuos en relación con la asistencia que les provee el seguro de desempleo. Por otra parte, en algunos países de América Latina se han implementado una serie de programas de transferencia de ingresos condicionados que se encuentran desvinculados de las políticas activas de empleo.

    The most important cerebrovascular injuries in newborn infants, particularly in preterm infants, are cerebral haemorrhage and ischemic injury. The typical cerebral vascular anatomy and the disturbance of cerebral haemodynamics play important roles in the pathophysiology. The term 'cerebral...... haemodynamics' includes cerebral blood flow (CBF), cerebral blood flow velocity, and cerebral blood volume (CBV). Therapy aimed at changing vascular anatomy is not available. Therefore, prevention of disturbances in CBF and CBV is pivotal. However, continuous monitoring of CBF and CBV is still unavailable for.......

Nine (64% of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more frequently in patients later found to have cerebral edema. Moreover, the length of time from deep coma to death was much shorter in the brain edema cases with cerebral herniation than without herniation.

Thirwall establece que las variables relevantes en la explicación del crecimiento económico son las elasticidades ingreso de las exportaciones e importaciones y el ingreso del resto del mundo. Esta última variable se aproxima, en este trabajo, por el PIB mundial. Los resultados obtenidos, al analizar el periodo 1929-2009, sugieren la existencia de una relación de largo plazo entre el PIB de México y el PIB mundial sólo durante el periodo 1988-2009. La dirección de la causalidad entre el PIB mundial y el de México, como era de esperarse, va del primero al segundo de acuerdo con la dinámica del modelo de corrección del error estimado. No se encontró evidencia de que ambas variables estuvieran relacionadas en un periodo más amplio, lo cual puede atribuirse a que la economía mexicana estaba prácticamente cerrada hasta antes de la década de los ochenta. Esto difiere de lo encontrado en otras investigaciones en donde se utiliza el PIB de Estados Unidos como proxy del PIB del resto del mundo.

  20. A comparative study between subjective assessment and quantitative evaluation of CT findings with cerebral palsy

    International Nuclear Information System (INIS)

    Computed tomography (CT) was performed on 200 children with children palsy with Hitachi CT-H250. The CT scans of 136 cases revealed cerebral atrophy with ventricular and/or subarachnoid space enlargement. The lateral ventricles, the third ventricle and the two parts of subarachnoid space on the CT picture were subjectively evaluated and divided into five grades ranging from no enlargement to marked enlargement. In addition, the size of the ventricles and the subarachnoid spaces were quantitatively determined; the transverse diameter of brain (b), the largest width of the anterior horns of the lateral ventricles (c), the bicaudate nuclear distance (d), the greatest width of the third ventricle, the longitudinal cerebral fissure and sylvian fissures as described by Miyao et al. (1978). Comparison of these quantitative techniques confirmed the initial subjective evaluation. However, in some cases, amendment of the subjective evaluation was needed. As mentioned before (Miyao et al.), the cerebral longitudinal fissure was relatively wide in normal infants. Accordingly, it was often difficult to find out abnormal widening only by subjective evaluation. The purpose of this paper was to establish the criteria of quantitative measuring and assessing of the lateral and third ventricles, the cerebral longitudinal fissurem, and the sylvian fissures enlargement. Interpretation of some problem cases associated with measuring was also discussed. The quantitative CT evaluation may be a good reference in assessing cerebral atrophy in cerebral palsy and other neurological diseases. (author)

    International Nuclear Information System (INIS)

    For the purpose of studying the incidence, pathomorphology and etiology of asymptomatic ischemic cerebral lesions, we carried out a brain MRI study on 65 patients with diabetes mellitus accompanied with hypertension who are thought to belong to a high risk group of ischemic cerebrovascular diseases. Excluding the abnormality of tendon reflex due to diabetic neuropathy, sixty percent of the total patients had some mild neurological signs and symptoms, most of them was discrepancy in tendon reflex. The percentage of the patients in whom MRI disclosed some abnormalities was as high as 70%, they were lacunar stroke, multiple lacunar state, cortical infarct, and patchy high signal lesions visible only in the T2 weighted image. Lacunes or these patchy high signal lesions (considered to be the dilatation of the perivascular space or true lacunes) tended to be found along the border zone or the terminal zone. These results indicate that asymptomatic patients in whom MRI discloses the abnormalities should be considered as candidates for the future onset of multi-infarct. (author)

  3. [Plasma osmolarity and cerebral volume].

    Science.gov (United States)

    Boulard, G

    2001-02-01

    Under normal physiological conditions, the osmolarity of extracellular fluids (ECFs) and natremia are controlled by two regulatory mechanisms modulating the water balance and sodium outflow from information collected by the osmoreceptors and baroreceptors, respectively. As well, under normal physiological conditions, water and electrolytes of brain ECFs are secreted by the endothelial cells of brain capillaries. Furthermore, isotonicity is present on both sides of the blood-brain barrier. In the event of systemic osmolarity disorders, water transport subject to osmosis laws occurs at the level of the blood-brain barrier. In the case of plasmatic hyperosmolarity cerebral dehydration is observed, while cerebral edema occurs in the contrary case. However, plasmatic osmolarity disorders have less effect on the cerebral volume when their introduction is slow. Experimentation in acute conditions shows that measured variations of the cerebral water content are lower than calculated variations, thus suggesting the existence of an adaptive mechanism, that is, the cerebral osmoregulation which limits the variation of the volume of brain cells by modulating their osmoactive molecule content. These osmoactive molecules are, on the one hand, the electrolytes, which are early and rapidly mobilized, and, on the other hand, the organic osmoles (amino acids, etc.), whose secretion is slower and delayed. This phenomenon should be taken into account in the treatment of osmolarity disorders. Thus, the related-risk of treatment for natremia disorders is therapeutic reversal of the osmotic gradient at the level of the blood-brain barrier. This reversal, which corresponds to a second osmotic stress, requires the implementation of a new procedure of cerebral osmoregulation in the opposite direction of the preceding one. As successive osmotic stresses decrease the effectiveness of brain osmoregulation, the risk for cerebral dehydration and pontine myelinolysis increases when the treatment

For this purpose we analyze the data on this program’s recipients during the period from 2004 to 2010, with the aim of testing a series of basic indicators for describing this collective and especially for comparing the autochthonous and immigrant populations. Besides determining the characteristics of the two collectives and identifying differential patterns on their presence in benefit provision, the final aim is to contribute to comparing certain existing perceptions on the use of social benefits by the immigrant collective. In the results we underscore differences between the socio-demographic profiles of the two collectives in aspects like age, sex, marital status or municipality of residence. At the same time, we analyze aspects like the duration of the period receiving benefits and we detect a greater receipt of social benefits by the foreign population. We also employ certain indices for identifying states of chronicity (maximum uninterrupted receipt for at least two years, which also reveal an increasingly unfavorable situation amongst foreigners and even make it possible to identify certain national collectives that stand out due to their greater chronicity – Romanians and sub-Saharan Africans.En este artículo realizamos un primer análisis de la base de datos de personas perceptoras de la prestación de la Renta de Garantía de Ingresos —el programa de rentas mínimas en la Comunidad Autónoma del País Vasco (CAPV— en Vizcaya entre 2004 y 2010, con el objeto de probar una serie de indicadores básicos para la descripción del colectivo y, especialmente, para la comparación de las poblaciones autóctona e inmigrante.

    The Mexican Farming Sector has a great potential to help solve the worldwide problems caused by greenhouse effect gases (GEI). The Kyoto Protocol is an instrument created to reduce the greenhouse effect gases (GEI) and it also is the fundament of the AgCert project -which consists in applying own financial resources to develop technological options that contribute to the reduction of greenhouse effect gases in cattle productive facilities and to use the income to economically support the producers. In this document it is described the way in which the biodigestor was installed, demonstrating that the MDL for farming projects is a tool to reduce the discharges of greenhouse effect gases. It also demonstrates that technologies and processes can be applied systematically to reduce the emissions of the GEI, bringing along environmental and economic benefits.

  10. Primary cerebral lymphoma

    International Nuclear Information System (INIS)

    The aim of this study is to compare the survival of the patients treated with radiotherapy alone vs. patients treated with a combined schedule of radio-chemotherapy. Our results will be compared with currently published data and main prognostic factors will be briefly discussed. Patients and methods: Between 1974 and 1990, 27 cases of primary cerebral lymphoma were diagnosed at our institution. All patients had biopsy-proven disease, the pathology of which was reviewed for this study. Results: The overall median survival time was 24 months and one-, two- and three-year overall survival was 59, 46 and 29% respectively. The median radiation dose was 46 Gy, ranging from 19.5 to 60 Gy. The median dose per fraction was 2 Gy (ranging from 1.61 to 3 Gy). The median elapsed treatment time was 32 days (ranging from three to 45 days). We were not able to demonstrate any statistically significant difference between patients who received radiotherapy alone (n = 14, median survival time = 24 months) and those who received a combination of chemotherapy and radiotherapy (n = 11, median survival time = 30 months), (p = 0.4). Prognostic factors of survival were tested using a univariate analysis (Wilcoxon test). Parameters such as mass appearance (unilobular, p = 0.048), performance status at the time of the diagnosis (0 to 1, p = 0.014), and CT imaging (hypodense, p = 0.043) influenced positively survival. Centroblastic histology (Kiel) was found associated with a negative prognosis (p = 0.043). (orig./MG)

    Cerebritis is part of a continuum of brain infection and is difficult to diagnose. Cerebritis caused by Klebsiella in immunocompetent adults without predisposing factors such as neurosurgery or penetrating brain injury has not been reported before. We report a case of Klebsiella cerebritis in an adult patient with a proven extracranial focus of infection. We suggest considering cerebritis as a differential diagnosis for altered level of consciousness in patients of severe sepsis, even if an extracranial source of infection is proven. PMID:19881180

    This was a retrospective study to determine different etiologies of cerebral venous thrombosis (CVT) in childhood and to correlate extent and location of thrombosis with the etiology and the age of the child as well as the final outcome. In addition, the radiologic approach is discussed. This was a retrospective analysis of 19 children with CVT. The children were examined by contrast-enhanced dynamic CT. Radiologic findings were correlated with the etiology of CVT. Cerebral venous thrombosis is not as infrequent in children as has been thought. Cerebral venous thrombosis in children can occur due to trauma (n=9), infections (n=7), or coagulation disorders (n=3). Extent and location of thrombosis, as well as complications, final outcome, and therapy, depend on the etiology. Computed tomography remains a valuable primary imaging modality in the diagnosis of CVT in the acutely injured or diseased child. (orig.)

    Autophagy has evolved as a conserved process for the bulk degradation and recycling of cytosolic components,such as long-lived proteins and organelles.In neurons,autophagy is important for homeostasis and protein quality control and is maintained at relatively low levels under normal conditions,while it is upregulated in response to pathophysiological conditions,such as cerebral ischemic injury.However,the role of autophagy is more complex.It depends on age or brain maturity,region,severity of insult,and the stage of ischemia.Whether autophagy plays a beneficial or a detrimental role in cerebral ischemia depends on various pathological conditions.In this review,we elucidate the role of neuronal autophagy in cerebral ischemia.

    Li'an Huang; Xuewen Song; Anding Xu

    2008-01-01

    BACKGROUND: It is crucial to understand cerebral perfusion and vascular reserve in stegnotic arterial blood-supply regions to treat ischemic cerebrovascular diseases. However, effects on symptomatic intracrani-al arterial stenosis (SICAS) need to be further studied in additional applications. OBJECTIVE: To evaluate and summarize the effects of cerebral perfusion and vascular reserve on the treatment of SICAS. RETRIEVAL STRATEGY: A computer-based online search of English language publications from January 2000 to July 2007 was conducted in PubMed to identify publications that addressed cerebral perfusion and vascular reserve of SICAS. Search key words were "intracranial stenosis, perfusion, brain reserve". Relevant data were also searched with the China Journal Net, using the same key words in Chinese from January 2000 to January 2007. In total, 101 articles were retrieved. Inclusion criteria: ① Articles describing the current status for the diagnosis and treatment of SICAS; ② Articles concerning research developments of cerebral perfusion and vascular reserve of SICAS. Exclusion criteria: duplicated articles. LITERATURE EVALUATION: This study included 21 articles of experimental studies and conference re-ports.DATA SYNTHESIS: When performing interventional surgery in SICAS patients, it is important to under-stand cerebral perfusion and vascular reserve in addition to knowing the clinical symptoms and degrees of arterial stenosis. In recent years, there are a growing number of reports on measurements of vascular reserve through the use of magnetic resonance perfusion imaging (MR-PWI). Investigations demonstrate cerebral perfusion and vascular reserve decrease in many SICAS patients. Many studies show that both improve after surgical intervention. CONCLUSION: Cerebral perfusion could provide direct evidence of whether ischemia has occurred in the brain. Because of lateral circulation and cerebral vascular reserve, intracranial vascular stenosis and/or decreased

  4. In Utero Electroporation: Assay System for Migration of Cerebral Cortical Neurons

    Science.gov (United States)

    Tabata, Hidenori; Nakajima, Kazunori

    During the development of the cerebral cortex, the majority of cortical neurons are generated in the ventricular zone (VZ) facing the lateral ventricle and then migrate toward the pial surface to form the highly organized 6-layered cerebral cortex. Detailed profiles of these processes and their molecular mechanisms had been largely unknown because of the absence of an efficient assay system. The in vivo electroporation system was initially devised for use within chick embryos (Funahashi et al., 1999; Itasaki et al., 1999; Momose et al., 1999; Muramatsu et al., 1997), and we and other groups have used that system as a basis for developing an in utero electroporation system, which allows plasmid DNA to be introduced into cortical progenitor cells in developing mouse embryos in the uterus (Fukuchi-Shimogori and Grove, 2001; Saito and Nakatsuji, 2001; Tabata and Nakajima, 2001; Takahashi et al., 2002). In utero electroporation of other sites in the brain, including the hippocampus (Navarro-Quiroga et al., 2007), cerebral basal ganglia (Borrell et al., 2005; Nakahira et al., 2006), cortical hem (Takiguchi-Hayashi et al., 2004), and dorsal thalamus (Bonnin et al., 2007), has recently been reported. Introducing green fluorescent protein (GFP) enables the entire processes of migration and layer formation to be visualized (Ajioka and Nakajima, 2005; Sasaki et al., 2008; Tabata and Nakajima, 2002, 2003), and the role of any gene involved in these processes can be easily assessed by overexpressing the proteins or their mutants (Ohshima et al., 2007), or by knocking down the genes by the RNA interference technique (Bai et al., 2003). Furthermore, the Tet-On/Off system and/or other plasmid- vector-based technologies will expand the potential of the analyses. In this section we review the principles and methods of gene transfer into the cortical wall of mouse embryos by means of the in utero electroporation system.

    Full Text Available Introduction Neurotoxoplasmosis (NT sometimes manifests unusual characteristics. Methods We analyzed 85 patients with NT and AIDS according to clinical, cerebrospinal fluid, cranial magnetic resonance, and polymerase chain reaction (PCR characteristics. Results In 8.5%, focal neurological deficits were absent and 16.4% had single cerebral lesions. Increased sensitivity of PCR for Toxoplasma gondii DNA in the central nervous system was associated with pleocytosis and presence of >4 encephalic lesions. Conclusions Patients with NT may present without focal neurological deficit and NT may occur with presence of a single cerebral lesion. Greater numbers of lesions and greater cellularity in cerebrospinal fluid improve the sensitivity of PCR to T gondii.

    We use an autonomous three-dimensional dynamical system to study embedded vortex structures that are observed to form in computational fluid dynamic simulations of patient-specific cerebral aneurysm geometries. These structures, described by a vortex which is enclosed within a larger vortex flowing in the opposite direction, are created and destroyed in phase space as fixed points undergo saddle-node bifurcations along vortex core lines. We illustrate how saddle-node bifurcations along vortex core lines also govern the formation and evolution of embedded vortices in cerebral aneurysms under variable inflow rates during the cardiac cycle.

    Cerebral oedema can be classified as the tangible swelling produced by expansion of the interstitial fluid volume. Hydrocephalus can be succinctly described as the abnormal accumulation of cerebrospinal fluid (CSF) within the brain which ultimately leads to oedema within specific sites of parenchymal tissue. Using hydrocephalus as a test bed, one is able to account for the necessary mechanisms involved in the interaction between oedema formation and cerebral fluid production, transport and drainage. The current state of knowledge about integrative cerebral dynamics and transport phenomena indicates that poroelastic theory may provide a suitable framework to better understand various diseases. In this work, Multiple-Network Poroelastic Theory (MPET) is used to develop a novel spatio-temporal model of fluid regulation and tissue displacement within the various scales of the cerebral environment. The model is applied through two formats, a one-dimensional finite difference - Computational Fluid Dynamics (CFD) coupling framework, as well as a two-dimensional Finite Element Method (FEM) formulation. These are used to investigate the role of endoscopic fourth ventriculostomy in alleviating oedema formation due to fourth ventricle outlet obstruction (1D coupled model) in addition to observing the capability of the FEM template in capturing important characteristics allied to oedema formation, like for instance in the periventricular region (2D model).

    We evaluated 35 patients with cerebral palsy on the basis of MR imaging findings in the brain. The types of palsy were spastic quadriplegia (n=11), spastic diplegia (n=9), spastic hemiplegia (n=2), double hemiplegia (n=1), athetosis (n=10) and mixed (n=2). Of all patients, 28 (80%) generated abnormal findings. In spastic quadriplegia, although eight cases revealed severe brain damage, two cases showed no abnormal findings in the brain. One of the three had cervical cord compression caused by atlanto-axial subluxation. In spastic diplegia, the findings were divided according to whether the patient was born at term or preterm. If the patient had been born prematurely, the findings showed periventricular leukomalacia and abnormally high intensity in the posterior limbs of the internal capsule on T2-weighted images. MR imaging in spastic hemiplegia revealed cerebral infarction. In the athetoid type, half of all cases showed either no abnormal findings or slight widening of the lateral ventricle. Three cases showed abnormal signals of the basal ganglia. The reason why athetoid-type palsy did not show severe abnormality is unknown. We believe that MR imaging is a useful diagnostic modality to detect damage in the brain in cerebral palsy and plays an important role in the differentiation of cerebral palsy from the spastic palsy disease.

    Full Text Available Las enfermedades cerebrovasculares son consecuencia de una alteración en la circulación cerebral. Su forma más distintiva de presentación es el ictus, entendido como un déficit neurológico focal de instauración brusca y evolución rápida. Un infarto cerebral de origen oclusivo puede deberse bien a una trombosis in situ o bien a una embolia procedente de un foco distante. En las embolias cerebrales la causa principal son los trombos murales cardiacos y el área encefálica afectada con mayor frecuencia es el territorio irrigado por la arteria cerebral media. Presentamos el caso de una mujer de 81 años, con antecedentes de Hepatitis C, cardiopatía hipertensiva y fibrilación auricular crónica, que sufrió una fractura de cadera consecutiva a una caída accidental. Durante el ingreso hospitalario comenzó un cuadro de deterioro neurológico progresivo que no llegó a ser filiado, falleciendo 9 días después. En la autopsia médico-forense se encontró un infarto cerebral hemorrágico en el territorio de la arteria cerebral media izquierda. Dado que las arterias del Polígono de Willis eran permeables y ante la presencia de trombos vitales adheridos a la pared del ventrículo derecho, se estimó como causa más probable del accidente vasculocerebral la embolización de uno de dichos trombos.Cerebrovascular diseases are due to a disturbance in cerebral blood flow. The most frequent way of presentation is stroke, defined as a sudden and focal neurological impairment with rapid evolution. Cerebral infarction of occlusive origin can be secondary to in situ thrombosis or to embolism from a distal focus. Mural thrombi are the main cause of brain embolism and the middle cerebral artery territory is the most likely affected brain area. We report the case of an 81 year-old woman, with antecedents of Hepatitis C, hypertensive cardiopathy and chronic atrial fibrillation, who suffered a hip fracture due to an accidental fall.

    Full Text Available Background/Aim. The effect of drugs leaves permanent consequences on the brain, organic in type, followed by numerous manifestations, and it significantly affects the development of mental dysfunctions. The clinicians are often given a task to estimate a patient’s personality during treatment or during experts estimate of a drug addict. The aim of this research was to determine the differences, if any, in characteristics of addicts experience and personality traits in drug addicts with or without cerebral edema. Methods. The research was conducted on a sample of 252 male drug addicts, the average age of 23.3 (SD = 4.3 years. Cerebral edema was confirmed on magnetic resonance (MR images of the brain performed during the treatment of the addicts. The participants were tested by the psychologists using Minnesota Multiphasic Personality Inventory (MMPI-201 test, and the data were processed using canonical discriminate analysis within the SPSS program. The dependent variable in the study was cerebral edema. A block of independent variables, designed for the requirements of this study, consisted of two subgroups. The first one consisted of 12 variables describing the relevant characteristics of drug abuse. The second subgroup consisted of 8 psychopathological tendencies in the personality defined by the mentioned test. Results. Cerebral edema was confirmed in 52 (20.63% of the drug addicts. The differences between the groups of drug addicts with and without cerebral edema were determined in the following: the time span of taking drugs (0.301, use of alcohol parallel with drugs (0.466, and treatment for addiction (0.603. In the drug addicts with a cerebral edema, MMPI-201 confirmed the increase in the scales for hypochondria, psychopathic deviations and psychastenia, and the decrease in the scales for schizophrenia and depression. Conclusion. Our study confirmed a possible connection between cerebral edema and personality traits in a number of the

    Full text: The clinical value of Tc-99m HMPAO SPECT cerebral blood flow studies in cognitive and neuropsychiatric disorders has been well described. Currently, interpretation of these studies relies on qualitative or semi- quantitative techniques. The aim of our study is to generate statistical measures of regional cerebral perfusion in the normal elderly using statistical parametric mapping (Friston et al, Wellcome Department of Cognitive Neurology, London, UK) in order to facilitate the objective analysis of cerebral blood flow studies in patient groups. A cohort of 20 healthy, elderly volunteers, aged 68 to 81 years, was prospectively selected on the basis of normal physical examination and neuropsychological testing. Subjects with risk factors, or a history of cognitive impairment were excluded from our study group. All volunteers underwent SPECT cerebral blood flow imaging, 30 minutes following the administration of 370 MBq Tc-99m HMPAO, on a Trionix Triad XLT triple-headed scanner (Trionix Research Laboratory Twinsburg, OH) using high resolution, fan-beam collimators resulting in a system resolution of 10 mm full width at half-maximum (FWHM). The SPECT cerebral blood flow studies were analysed using statistical parametric mapping (SPM) software specifically developed for the routine statistical analysis of functional neuroimaging data. The SPECT images were coregistered with each individual`s T1-weighted MR volume brain scan and spatially normalized to standardised Talairach space. Using SPM, these data were analyzed for differences in interhemispheric regional cerebral blood flow. Significant asymmetry of cerebral perfusion was detected in the pre-central gyrus at the 95th percentile. In conclusion, the interpretation of cerebral blood flow studies in the elderly should take into account the statistically significant asymmetry in interhemispheric pre-central cortical blood flow. In the future, clinical studies will be compared to statistical data sets in age

    1978-04-01

    Full Text Available This study demonstrates that an adrenergic mechanism plays an important role in producing the delayed cerebral vasospasm which follows subarachnoid hemorrhage. Results were as follows: 1. Experimental subarachnoid hemorrhage (SAH was produced by injection of fresh arterial blood into the cisterna magna in cats. The cerebral vasospasm was shown angiographically to be biphasic in nature: immediate constriction lasting 1 h and marked prolonged spasm occurring between the 3rd and 5th day after SAH. The amount of noradrenaline (NA and dopamine-beta-hydroxylase (DBH activity decreased over a period of 24 h both within the wall of the basilar artery and in the locus ceruleus and then gradually increased, reaching a maximum on the 3rd day after SAH. 2. Topical application of spasmogenic substances (NA and blood produced a marked constriction of the hypersensitive basilar artery on the 3rd day after SAH. 3. 6-Hydroxydopamine (6-OHDA injection into the cisterna magna produced prolonged vasocilatation. The dilated vessel responded with mild transient constriction after the topical application of NA or fresh blood. DBH activity and NA concentration in the vessels, locus ceruleus and medial hypothalamus decreased markedly on the 3rd day after the cisternal injection of 6-OHDA. 4. Various spasmogenic substances (i.e. serotonin, NA, prostaglandins and methemoglobin were measured in a mixture of equal volume of CSF and blood in cats. ONly the serotonin in the mixed fluid produced vasoconstriction. Spasmogenic substances decreased markedly in the mixed fluid incubated for 3 days at 37 degrees C, and none of these substances apart from methemoglobin was present in a concentration sufficient to produce constriction of vessels. 5. These results suggest that early spasm is induced by serotonin around the arteries of the cranial base, and delayed spasm might be caused by hyperreaction of cerebral vessels to spasmogenic substances such as methemoglobin, during the

    BACKGROUND: Studies have demonstrated that triptolide has good anti-inflammatory and immunosuppressive effects. However, the effect of triptolide on cerebral ischemia/reperfusion injury is still unclear.OBJECTIVE: To observe the effects of triptolide on neurologic function, infarct volume, water content of brain tissue, neutrophil number in microvascular wall and intedeukin-1β (IL-1β ) expression in rat models of local ischemia/reperfusion, and analyze the mechanism of triptolide for protecting brain.DESIGN: Randomized controlled experiment.SETTING: Department of Pathology, Medical School of Ningbo University; Department of Forensic Medicine, Tongji Medical College of Huazhong University of Science and Technology.MATERIALS: Sixty Wistar rats of either gender, aged 4 months old, weighing from 200 to 250 g, were provided by the Experimental Animal Center, Tongji Medical College, Huazhong University of Science and Technology. Triptolide was purchased from Fujian Institute for Medical Science (purity 99.98%; Batch No.2000215). It was dissolved in 20 g/L propanediol, and filtered with 200-mesh filter for later use.METHODS: This experiment was carried out in the laboratory of Forensic Medicine, Tongji Medical College of Huazhong University of Science and Technology, Department of Pathology, Medical School of Ningbo University between January 2001 and September 2004. ① Sixty Wistar rats were randomized into 4 groups: sham-operation group, model group, low-dose triptolide group and high-dose triptolide group. Rats in each group, except for sham-operation group, were developed into rat models of cerebral ischemia/reperfusion according to the method of Longa et al.

    This study has identified the active cerebral areas of normal Chinese that are associated with Chinese semantic processing using functional brain imaging. According to the traditional cognitive theory, semantic processing is not particularly associated with or affected by input modality. The functional brain imaging experiments were conducted to identify the common active areas of two modalities when subjects perform Chinese semantic tasks through reading and listening respectively. The result has shown that the common active areas include left inferior frontal gyrus (BA 44/45), left posterior inferior temporal gyrus (BA37); the joint area of inferior parietal lobules (BA40) and superior temporal gyrus, the ventral occipital areas and cerebella of both hemispheres. It gives important clue to further discerning the roles of different cerebral areas in Chinese semantic processing.

    2015-11-01

    Cerebral ischemia remains one of the most frequent causes of death and disability worldwide. Animal models are necessary to understand complex molecular mechanisms of brain damage as well as for the development of new therapies for stroke. This review considers a certain range of animal models of cerebral ischemia, including several types of focal and global ischemia. Since animal models vary in specificity for the human disease which they reproduce, the complexity of surgery, infarct size, reliability of reproduction for statistical analysis, and adequate models need to be chosen according to the aim of a study. The reproduction of a particular animal model needs to be evaluated using appropriate tools, including the behavioral assessment of injury and non-invasive and post-mortem control of brain damage. These problems also have been summarized in the review.

METHOD: Single case report. RESULT: Man 52 years old, 20 years after going through a total thyroidectomy, starts showing behavioral disturbance (psychotic syndrome. He was diagnosed as schizophrenic (paranoid subtype and submitted to outpatient psychiatric treatment. During a psychiatric admission to evaluate his progressive cognitive and motor deterioration, we identified a dementia syndrome and extensive cerebral calcifications, derived from iatrogenic hypoparathyroidism. CONCLUSION: The calcium and phosphorus disturbances, including hypoparathyroidism, are common causes of CC. Its symptoms can imitate psychiatric disorders and produce serious and permanent cognitive sequelae. The exclusion of organicity is mandatory in any psychiatric investigative diagnosis in order to avoid unfavorable outcomes, such as in the present case report.

    Increased intracranial pressure is common in cerebral venous thrombosis (CVT), but hydrocephalus is rarely reported in these patients. We examined the frequency, pathophysiology and associated clinical manifestations of hydrocephalus in patients with CVT admitted to our hospital between 2000 and 2010 (prospectively since July 2006). Hydrocephalus was defined as a bicaudate index larger than the 95th percentile for age, and/or a radial width of the temporal horn of ≥ 5 mm. We excluded patients in whom hydrocephalus was caused by a disease other than CVT or if it was iatrogenic. 20 out of 99 patients with CVT had hydrocephalus. 6 patients with hydrocephalus were excluded from the analysis. Patients with hydrocephalus more often had focal neurological deficits (86 vs. 49%, p = 0.02) and were more frequently comatose (43 vs. 16%, p = 0.06), as compared to patients without hydrocephalus. Deep cerebral venous thrombosis (64 vs. 9%, p hydrocephalus. Intraventricular hemorrhage was present in 1 patient with hydrocephalus, compared to none among patients without hydrocephalus (7 vs. 0%, p = 0.15). Outcome at follow-up was worse in patients with hydrocephalus (mRS 0-1, 36 vs. 68%, p = 0.02; mortality 29 vs. 9%, p = 0.07). Hydrocephalus occurs more frequently in cerebral venous thrombosis than previously believed, especially in patients with deep cerebral venous thrombosis and edema of the basal ganglia. The presence of hydrocephalus is associated with a worse clinical outcome, but a direct causal relation is unlikely. Routine shunting procedures are not advisable.

  17. Clinical studies on cerebral infarction

    International Nuclear Information System (INIS)

    Hemorrhagic infarction (HI) is termed as the infarction in which a large part of the necrotic tissue is stippled with small hemorrhage. The pathogenetic mechanism of this disease still remains controversial. Cerebral infarction has long been divided into two subtypes-thrombosis and embolism-according to the pathogenetic mechanisms. Clinical studies were carried out in 31 cases of HI with cerebral thrombosis. CT findings of these cases were classified into five groups according to both size of low density area which indicates regions of infarction and distribution of arterial supply. The low density area of Type I-Type III were observed in the area of the middle cerebral artery. That of Type IV was observed in the area of the internal capsule and basal ganglia. That of Type V was observed in the area of the posterior cerebral artery. CT reveals two patterns of HI -pattern A and pattern B-. The CT finding of pattern A is appearance of high density area in the low density area. The CT finding of pattern B is appearance of iso density area in the low density area. rCBF was measured by 133Xe inhalation technique in 21 patients with CT type I, II and III. Thereafter, with regard to the various findings in CT, the clinical findings and CBF findings, a comparative study was carried out on these ten groups. From the results of present studies, it is concluded that sequential changes of CBF in cases with pattern A are different from those with pattern B, and that CBF measurement does not permit an estimation of a patient's chance for functionary recovery after a stroke in acute and subacute stage but permits estimation of functional outcome in chronic stage.

  9. Cerebral blood flow and metabolism in multi-infarct dementia

    International Nuclear Information System (INIS)

    Cerebral blood flow and oxygen metabolism were studied in three aged normal volunteers and 10 patients with multi-infarct dementia (MID) by Positron Emission Tomography using O-15. The diagnosis of MID was done according to the Loeb's modified ischemic score and X-ray CT findings. The MID patients, whose X-ray CT showed localized low density areas in the subcortical white matter and basal ganglia and thalamus, were studied. No occulusion was observed at anterior cerebral artery and/or middle cerebral artery on cerebral angiography. All cases of MID were mild dementias. Regional CBF, rOEF and rCMRO2 were measured by the steady state technique described by Terry Jones et al. The values of rCBF in MID patients were significantly low compared with those of aged normal subjects in frontal, temporal, occipital, parietal cortices and thalamus. The values of CMRO2 in MID were significantly low in frontal, temporal, occipital cortices and thalamus compared with normal subjects'. The OEF was 0.46 in aged normal subjects, and 0.52 in MID patients. The MID patients in the early stage of dementia showed the increased oxygen extraction fraction, and this fact suggests that ischemia is a significant pathogenic mechanism in the production and progression of multi-infarct dementia. The decrease of CBF and CMRO2 in MID compared from normal subjects' were most remarkable in frontal cortex.

    Full Text Available Cerebral complications are important, but poorly understood pathological features of infections caused by some species of Plasmodium and Babesia. Patients dying from P. falciparum were classified as cerebral or non-cerebral cases according to the cerebral malaria coma scale. Light microscopy revealed that cerebral microvessels of cerebral malaria patients were field with a mixture of parazited and unparazited erythrocytes, with 94% of the vessels showing parasitized red blood cell (PRBC sequestration. Some degree of PRBC sequestration was also found in non-cerebral malaria patients, but the percentage of microvessls with sequestered PRBC was only 13% Electron microscopy demonstrated knobs on the membrane of PRBC that formed focal junctions with the capillary endothelium. A number of host cell molecules such as CD36, thrombospondim (TSP and intracellular adhesion molecule I (ICAM-1 may function as endothelial cell surfacereports for P. falciparum-infected erythrocytes. Affinity labeling of CD36 and TSP to the PRBC surface showed these molecules specifically bind to the knobs. Babesia bovis infected erythrocytes procedure projections of the erythrocyte membrane that are similar to knobs. When brain tissue from B. bovis-infected cattle was examined, cerebral capillaries were packed with PRBC. Infected erythrocytes formed focal attachments with cerebral endothelial cells at the site of these knob-like projections. These findings indicate that cerebral pathology caused by B. bovis is similar to human cerebral malaria. A search for cytoadherence proteins in the endothelial cells may lead to a better understanding of the pathogenisis of cerebral babesiosis.

    Full Text Available Cerebritis is part of a continuum of brain infection and is difficult to diagnose. Cerebritis caused by Klebsiella in immunocompetent adults without predisposing factors such as neurosurgery or penetrating brain injury has not been reported before. We report a case of Klebsiella cerebritis in an adult patient with a proven extracranial focus of infection. We suggest considering cerebritis as a differential diagnosis for altered level of consciousness in patients of severe sepsis, even if an extracranial source of infection is proven.

    Full Text Available Abstract Definition of the disease AL amyloidosis results from extra-cellular deposition of fibril-forming monoclonal immunoglobulin (Ig light chains (LC (most commonly of lambda isotype usually secreted by a small plasma cell clone. Most patients have evidence of isolated monoclonal gammopathy or smoldering myeloma, and the occurrence of AL amyloidosis in patients with symptomatic multiple myeloma or other B-cell lymphoproliferative disorders is unusual. The key event in the development of AL amyloidosis is the change in the secondary or tertiary structure of an abnormal monoclonal LC, which results in instable conformation. This conformational change is responsible for abnormal folding of the LC, rich in β leaves, which assemble into monomers that stack together to form amyloid fibrils. Epidemiology AL amyloidosis is the most common type of systemic amyloidois in developed countries with an estimated incidence of 9 cases/million inhabitant/year. The average age of diagnosed patients is 65 years and less than 10% of patients are under 50. Clinical description The clinical presentation is protean, because of the wide number of tissues or organs that may be affected. The most common presenting symptoms are asthenia and dyspnoea, which are poorly specific and may account for delayed diagnosis. Renal manifestations are the most frequent, affecting two thirds of patients at presentation. They are characterized by heavy proteinuria, with nephrotic syndrome and impaired renal function in half of the patients. Heart involvement, which is present at diagnosis in more than 50% of patients, leading to restrictive cardiopathy, is the most serious complication and engages prognosis. Diagnostic methods The diagnosis relies on pathological examination of an involved site showing Congo red-positive amyloid deposits, with typical apple-green birefringence under polarized light, that stain positive with an anti-LC antibody by immunohistochemistry and

    Full Text Available EI vaso espasmo cerebral es la principal causa tratable de muerte e incapacidad por hemorragia subaracnoidea espontánea secundaria a la ruptura de un aneurisma cerebral. Sin embargo, su tratamiento ha sido tradicionalmente frustrante, con resultados desalentadores. A pesar de que aún no se han aclarado del todo los mecanismos fisiopatológicos a través de los cuales ocurre este intrigante fenómeno, en los últimos 9 años, paralelamente al desarrollo de las técnicas endovasculares para el tratamiento de las enferm~dades cerebrovasculares, han surgido nuevas alternativas en el manejo del vasoespasmo cerebral. Entre ellas se destacan el uso intraarterial de papaverina y la angioplastia con balón de los vasos cerebrales. Se presenta una revisión del estado actual de estos novedosos instrumentos terapéuticos, así como el reporte de un caso en el cual usamos la papaverina intraarterial en el tratamiento del vasoespasmo quese presentó durante un procedimiento endovascular para excluir un aneurisma de la arteria cerebral media. Cerebral vasospasm is the first treatable cause of death and disability secondary to spontaneous subarachnoid hemorrhage due to ruptured cerebral aneurysms. However, its treatment has been disapointing with poor results. Despite the fact that the physiopathologic mechanisms governing this phenomenon are largely unknown, during the last nine years, simultaneously with the development of endovascular therapy techniques for treatment of cerebrovascular diseases, two new alternatives have emerged in order to alleviate cerebral vasospasm: intraarterial papaverine and cerebral balloon angioplasty. We report the use of intraarterial papaverine in one case to treat cerebral vasospasm presented during the endovascular therapy procedure; a review of literature is included.

    Full Text Available Objective To explore the clinicopathological features, immune phenotype, diagnosis and differential diagnosis, treatment and prognosis of cerebral lipoastrocytoma. Methods Retrospective analysis of the clinical manifestations, histopathological and immunohistochemical features were conducted in one case of cerebral lipoastrocytoma. Results A 48-year-old male presented with numbness and inflexibility of the fourth and little fingers of his left hand over the previous 2 weeks. Cranial MRI revealed a space-occupying lesion with cystic degeneration in the right parietal lobe that showed obvious enhancement after contrast administration. The patient subsequently underwent craniotomy with stereotactic gross total excision of the lesion. Adjuvant chemotherapy and radiation therapy were not administered. Histologically the tumor showed classical features of low-grade astrocytoma, including a few scattered medium-large neuron-like cells with prominent nucleoli and abundant cytoplasm. Most notably, the glial cells contained fat droplets or vacuoles giving an appearance of mature adipocytes. Focally microcystic change was evident resulting from adipocyte-like cells fusion with each other. Immunohistochemically, the tumor cells were reactive for glial fibrillary acidic protein (GFAP and S-100 protein (S-100, focally positive for WT-1, weakly positive for oligodendrocytes transcription factor-2 (Olig-2, and negative for isocitrate dehydrogenase 1 (IDH1. Meanwhile, the tumor cells also expressed several neuronal markers including synaptophysin (Syn, microtube-associated protein-2 (MAP-2, neurofilament (NF, neuron specific enolase (NSE and CD34. P53 protein was weakly expressed in 5% of tumor cells. Ki-67 labeling index was low (1% . The patient remained well without recurrence 20 months after surgery. Conclusions Cerebral lipoastrocytoma is an extremely rare tumor. Histologically, the tumor showed classical features of low-grade astrocytoma and extensive

    Cerebral oximetry based on near-infrared spectroscopy (NIRS) is increasingly used during the perioperative period of cardiovascular operations. It is a noninvasive technology that can monitor the regional oxygen saturation of the frontal cortex. Current literature indicates that it can stratify patients preoperatively according their risk. Intraoperatively, it provides continuous information about brain oxygenation and allows the use of brain as sentinel organ indexing overall organ perfusion and injury. This review focuses on the clinical validity and applicability of this monitor for cardiac surgical patients. PMID:24672700

    Hyponatremia is the most frequent electrolyte disorder in critically neurological patients. Cerebral salt wasting syndrome (CSW) is defined as a renal loss of sodium during intracranial disease leading to hyponatremia and a decrease in extracellular fluid volume. The pathogenesis of this disorder is still not completely understood. Sympathetic responses as well as some natriuretic factors play a role in this syndrome. Distinction between SIADH and CSW might be difficult. The essential point is the volemic state. It is necessary to rule out other intermediate causes. Treatment requires volume replacement and maintenance of a positive salt balance. Mineral corticoids may be useful in complicated cases.

    We have analyzed HR changes greater than 20% among 334 patients and 942 cerebral angiographies. A tachycardial effect was seen in 14.9% of patients, while a bradycardial effect was seen in 7.1% including two patients having cardiac standstill (0.5%). These two patients were examined without atropine premedication after subarachnoid hemorrhage. Patients under 19 years of age, unpremedicated with atropine sulfate and suffering from subarachnoid hemorrhage secondary to ruptured aneurysm or arteriovenous malformation showed a significantly high incidence of bradycardia. On the other hand, patients with the neoplastic disease and having an initial sinus bradycardia showed a significantly high incidence of a tachycardial effect.

    Hypoxia-inducible factor-1 and its specific target gene heme oxygenase-1, are involved in acute cerebral ischemia. However, very few studies have examined in detail the changes in the hypox-ia-inducible factor-1/heme oxygenase-1 signaling pathway in chronic cerebral ischemia. In this study, a rat model of chronic cerebral ischemia was established by permanent bilateral common carotid artery occlusion, and these rats were treated with intragastric cilostazol (30 mg/kg) for 9 weeks. Morris water maze results showed that cognitive impairment gradual y worsened as the cerebral ischemia proceeded. Immunohistochemistry, semi-quantitative PCR and western blot analysis showed that hypoxia-inducible factor-1α and heme oxygenase-1 expression levels in-creased after chronic cerebral ischemia, with hypoxia-inducible factor-1α expression peaking at 3 weeks and heme oxygenase-1 expression peaking at 6 weeks. These results suggest that the elevated levels of hypoxia-inducible factor-1α may upregulate heme oxygenase-1 expression fol-lowing chronic cerebral ischemia and that the hypoxia-inducible factor-1/heme oxygenase-1 sig-naling pathway is involved in the development of cognitive impairment induced by chronic cerebral ischemia. Cilostazol treatment al eviated the cognitive impairment in rats with chronic cerebral is-chemia, decreased hypoxia-inducible factor-1α and heme oxygenase-1 expression levels, and re-duced apoptosis in the frontal cortex. These findings demonstrate that cilostazol can protect against cognitive impairment induced by chronic cerebral ischemic injury through an anti-apoptotic mecha-nism.

The causes of cerebral palsy were presumed to be as follows: abnormal cerebral development (36%), asphyxial delivery (34%), and immature delivery (19%), etc. CT findings were abnormal in 58% of the 73 cases, 83% of the spastic tetraplegia patients and all of the spastic hemiplegia patients showed abnormal CT findings. All the patients with spastic monoplegia presented normal CT findings. In 75% of the spastic hemiplegia cases, the CT abnormalities were due to cerebral parenchymal abnormality such as porencephaly and regional low absorption. In cases of spastic tetraplegia, cerebral parenchymal abnormality was found only in 10%. Cortical atrophy was found only in 15 of the 73 cases, whereas central atrophy was found in 36 cases.

  14. Cerebral cortex modulation of pain

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Pain is a complex experience encompassing sensory-discriminative, affective-motivational and cognitiv e-emotional com-ponents mediated by different mechanisms. Contrary to the traditional view that the cerebral cortex is not involved in pain perception, an extensive cortical network associated with pain processing has been revealed using multiple methods over the past decades. This network consistently includes, at least, the anterior cingulate cortex, the agranular insular cortex, the primary (SⅠ) and secondary somatosensory (SⅡ) cortices, the ventrolateral orbital cortex and the motor cortex. These corti-cal structures constitute the medial and lateral pain systems, the nucleus submedius-ventrolateral orbital cortex-periaque-ductal gray system and motor cortex system, respectively. Multiple neurotransmitters, including opioid, glutamate, GABA and dopamine, are involved in the modulation of pain by these cortical structures. In addition, glial cells may also be in-volved in cortical modulation of pain and serve as one target for pain management research. This review discusses recent studies of pain modulation by these cerebral cortical structures in animals and human.

    Cerebral vasospasm causes permanent neurolological deficit or death occurance in 13% of clinical cases. Peak frequency is from 8-10th day after SAH. The purpose of this study is factor analysis that may have influence on vasospasm development , as well as predictor determination. The study is prospective and analysis 192 patients treated in Institute of Neurosurgery, Clinical Centre of Serbia, Belgrade. The majority of patients were admitted in hospital in first four days after SAH, and 184 had GCS over 7. Univariate methods of factor analysis were used, and for significance of predictors influence testing multivariante regression analysis was used. Vasospasm occurred in 22,40% of all cases. No relationships have been found between sex, age, previous hypertension, timing of surgery, appearance of hydrocephalus and intracerebral hematoma, hypertermia or mean arterial blood pressure, with occurrence of cerebral vasospasm. Factors with significantly associated with the occurance of vasospasm were: hearth disease, hypernatriemia, Hct, clinical grade on admission as well as preoperative clinical grade and Fisher CT scan grade. In the first four days after SAH, Fisher scan grade, preoperative clinical grade and Hct, appeared as predictors. After four days, clinical grade on admission and hypernatiemia, showed as poredictors. PMID:18792575

    Cerebral asymmetries for L1 (Italian), L2 (English), and L3 (French, German, Spanish, or Russian) were studied, by using a verbal-manual interference paradigm, in a group of Italian right-handed polyglot female students at the Scuola Superiore di Lingue Moderne per Interpreti e Traduttori (SSLM-School for Interpreters and Translators) of the University of Trieste and in a control group of right-handed monolingual female students at the Medical School of the University of Trieste. In an automatic speech production task no significant cerebral lateralization was found for the mother tongue (L1) either in the interpreting students or in the control group; the interpreting students were not significantly lateralized for the third language (L3), while weak left hemispheric lateralization was shown for L2. A significantly higher degree of verbal-manual interference was found for L1 than for L2 and L3. A significantly higher disruption rate occurred in the meaning-based mode of simultaneous interpretation (from L2 into L1 and vice versa) than in the word-for-word mode (from L2 into L1 and vice versa). No significant overall or hemispheric differences were found during simultaneous interpretation from L1 into L2 or from L2 into L1. PMID:2207622

    Rehabilitation is a major goal for children with cerebral palsy, although the potential to enhance cardio-respiratory fitness in such individuals remains unclear. This study thus compared current cardio-respiratory status between children with cerebral palsy and able-bodied children, and examined the ability to enhance the cardio-respiratory fitness of children with cerebral palsy by cycle ergometer training. 10 children with cerebral palsy (Gross Motor Function Classification System levels I and II) participated in thrice-weekly 30 min cycle ergometer training sessions for 8 weeks (mean age: 14.2±1.9 yrs). 10 additional subjects with cerebral palsy (mean age: 14.2±1.8 yrs) and 10 able-bodied subjects (mean age: 14.1±2.1 yrs) served as controls, undertaking no training. All subjects undertook a progressive cycle ergometer test of cardio-respiratory fitness at the beginning and end of the 8-week period. Cardio-respiratory parameters [oxygen intake V˙O2), ventilation V ˙ E) and heart rate (HR)] during testing were measured by Cosmed K4 b gas analyzer. The children with cerebral palsy who engaged in aerobic training improved their peak oxygen consumption, heart rate and ventilation significantly (pchildren with cerebral palsy can benefit significantly from cardio-respiratory training, and such training should be included in rehabilitation programs.

    Cerebral ischemia after birth and during labor is a major cause of death and severe complications such as cerebral palsy. In the USA alone, cerebral palsy results in permanent disability of 10,000 newborns per year and approximately 500,000 of the total population. Currently, no technology is capable of direct monitoring of cerebral oxygenation in newborns. This study proposes the use of an optoacoustic technique for noninvasive cerebral ischemia monitoring by probing the superior sagittal sinus (SSS), a large central cerebral vein. We developed and built a multi-wavelength, near-infrared optoacoustic system suitable for noninvasive monitoring of cerebral ischemia in newborns with normal weight (NBW), low birth-weight (LBW, 1500 - 2499 g) and very low birth-weight (VLBW, cerebral oxygenation would suggest that no therapy was necessary; conversely, evidence of cerebral ischemia would prompt therapy to increase cerebral blood flow.

    Full Text Available Abstract Valvular strands, well-delineated filiform masses, attached to cardiac valve edges are associated with cerebral embolism and stroke. Strokes, caused by emboli from valvular strands, tend to occur among younger persons. In this case report a valvular strand, giving a peculiar serpentine appearance to the mitral valve is described. This mitral valvular strand was the only explanation for an episode of cerebral embolism, presenting with a transient right sided hemiparesis. It is proposed that a randomized study involving combined treatment with aspirin and clopidogrel is warranted in young patients with valvular strands, presenting with a first episode of cerebral embolism.

  4. Human cerebral circulation. Positron emission tomography studies

    International Nuclear Information System (INIS)

    We reviewed the literature on human cerebral circulation and oxygen metabolism, as measured by positron emission tomography (PET), with respect to normal values and of regulation of cerebral circulation. A multicenter study in Japan showed that between-center variations in cerebral blood flow (CBF), cerebral blood volume (CBV), cerebral oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO2) values were not considerably larger than the corresponding within-center variations. Overall mean±SD values in cerebral cortical regions of normal human subjects were as follows: CBF=44.4±6.5 ml/100 ml/min; CBV=3.8±0.7 ml/100 ml; OEF=0.44±0.06; CMRO2=3.3±0.5 ml/100 ml/min (11 PET centers, 70 subjects). Intrinsic regulation of cerebral circulation involves several factors. Autoregulation maintains CBF in response to changes in cerebral perfusion pressure; chemical factors such as PaCO2 affect cerebral vascular tone and alter CBF; changes in neural activity cause changes in cerebral energy metabolism and CBF; neurogenic control of CBF occurs by sympathetic innervation. Regional differences in vascular response to changes in PaCO2 have been reported, indicating regional differences in cerebral vascular tone. Relations between CBF and CBV during changes in PaCO2 and during changes in neural activity were in good agreement with Poiseuille's law. The mechanisms of vascular response to neural activation and deactivation were independent on those of responses to PaCO2 changes. CBV in a brain region is the sum of three components: arterial, capillary and venous blood volumes. It has been reported that the arterial blood volume fraction is approximately 30% in humans and that changes in human CBV during changes in PaCO2 are caused by changes in arterial blood volume without changes in venous blood volume. These findings should be considered in future studies of the pathophysiology of cerebrovascular diseases. (author) 136 refs

    Cerebral edema plays a central role in the pathophysiology of many diseases of the central nervous system (CNS) including ischemia, trauma, tumors, inflammation, and metabolic disturbances. The formation of cerebral edema results in an increase in tissue water content and brain swelling which, if unchecked, can lead to elevated intracranial pressure (ICP), reduced cerebral blood flow, and ultimately cerebral herniation and death. Despite the clinical significance of cerebral edema, the mechan...

    Full Text Available Num estudo retrospectivo de 1.071 necropsias de bovinos, foram encontrados 20 casos de babesiose cerebral confirmados pelo exame de esfregaços do córtex telencefálico. A maioria desses casos ocorreu no verão, em bovinos adultos de raças européias ou suas cruzas. Além dos sinais clínicos neurológicos, observou-se hemoglobinúria, anorexia, febre, taquicardia, taquipnéia e queda na produção de leite. O hemograma realizado em cinco bovinos afetados revelou acentuada anemia regenerativa; em média, 20% dos eritrócitos estavam parasitados por Babesia bovis. Na necropsia de todos os casos, a substância cinzenta dos córtices telencefálico e cerebelar e dos núcleos da base era consistente e caracteristicamente róseo-cereja. Essa coloração devia-se ao seqüestro de eritrócitos nos capilares encefálicos. Nesses eritrócitos, podiam-se observar, tanto em esfregaços do córtex como em preparações histológicas do encéfalo, microorganismos com morfologia compatível com B. bovis. Outros achados de necropsia incluíam hemoglobinúria, rins vermelho-escuros, hepatoesplenomegalia, fígado vermelho-alaranjado, icterícia, hemorragias epicárdicas e endocárdicas e edema e congestão dos linfonodos mesentéricos.

    2016-07-01

    Over the past few years there have been a number of case reports and small cohort studies that have described so called "malignant" cerebral swelling following an uneventful cranioplasty procedure. The pathophysiology remains to be established however it has been suggested that it may be related to a combination of failure of autoregulation and the use of closed vacuum suction drainage. The current study presents three further patients who had had a decompressive hemicraniectomy for ischaemic stroke. If decompressive craniectomy is utilised in the management of neurological emergencies, close attention and wider reporting of this type of complication is required not only to focus attention on possible management strategies, but also to determine which patients are at most risk of this devastating complication.

    Seventy patients who had suffered from severe damages in the brain in their early lives were examined using a CT scanner, DELTA-25. The results are summerized as follows: 1. CT findings of the brain were classified into four groups; (1) low density in 11 cases, (2) atrophy in 23, (3) hydrocephalus in 12, and (4) no findings in 24. 2. The low density in the CT finding was assumed as cystic degeneration due to circulatory disturbance in the cerebral hemispheres in their early developmental stages. 3. The ''acerebrate'' state denotes no or little development in mental and motor functions which is attributed to a severe damage in the developing brain. According to the CT findings, the ''acerebrate'' state was resulted from extensive destruction in the greater part of both hemispheres. (author)

    Full Text Available Background/Aim. Cerebral palsy (CP is one of the leading causes of neurological impairment in childhood. Preterm birth is a significant risk factor in the occurrence of CP. Clinical outcomes may include impairment of gross motor function and intellectual abilities, visual impairment and epilepsy. The aim of this study was to examine the relationships among gestational age, type of CP, functional ability and associated conditions. Methods. The sample size was 206 children with CP. The data were obtained from medical records and included gestational age at birth, clinical characteristics of CP and associated conditions. Clinical CP type was determined according to Surveillance of Cerebral Palsy in Europe (SCPE and topographically. Gross motor function abilities were evaluated according to the Gross Motor Function Classification System (GMFCS. Results. More than half of the children with CP were born prematurely (54.4%. Statistically significant difference was noted with respect to the distribution of various clinical types of CP in relation to gestational age (p < 0.001. In the group with spastic bilateral CP type, there is a greater proportion of children born preterm. Statistically significant difference was noted in the functional classification based on GMFCS in terms of gestational age (p = 0.049, children born at earlier gestational age are classified at a higher GMFCS level of functional limitation. The greatest percentage of children (70.0% affected by two or more associated conditions was found in the group that had extremely preterm birth, and that number declined with increasing maturity at birth. Epilepsy was more prevalent in children born at greater gestational age, and this difference in distribution was statistically significant (p = 0.032. Conclusion. The application of antenatal and postnatal protection of preterm children should be a significant component of the CP prevention strategy. [Projekat Ministarstva nauke Republike

  1. Cerebral malaria: gamma-interferon redux

    Directory of Open Access Journals (Sweden)

    Nicholas H Hunt

    2014-08-01

    Full Text Available There are two theories that seek to explain the pathogenesis of cerebral malaria, the mechanical obstruction hypothesis and the immunopathology hypothesis. Evidence consistent with both ideas has accumulated from studies of the human disease and experimental models. Thus some combination of these concepts seems necessary to explain the very complex pattern of changes seen in cerebral malaria. The interactions between malaria parasites, erythrocytes, the cerebral microvascular endothelium, brain parenchymal cells, platelets and microparticles need to be considered. One factor that seems able to knit together much of this complexity is the cytokine interferon-gamma. In this review we consider findings from the clinical disease, in vitro models and the murine counterpart of human cerebral malaria in order to evaluate the roles played by interferon-gamma in the pathogenesis of this often fatal and debilitating condition.

    Full Text Available Cerebral small vessel disease refers to a group of pathological processes with various etiologies that affect small arteries, arterioles, venules, and capillaries of the brain. Recently, the researches of cerebral small vessel disease have got initial progressions, and a definite diagnosis of this disease is comfirmed by biopsy. Given the pathological material is difficult to obtain, clinicians should pay more attention to the imaging features and clinical manifestations. Correct understanding of imaging and clinical manifestations contributes to the early identification of cerebral small vessel disease. Herein, an overview is provided on the present status, common imaging features, pathogenesis, clinical manifestations and treatment of cerebral small vessel disease. DOI: 10.3969/j.issn.1672-6731.2015.02.003

    Full Text Available Triad of leukoencephalopathy, cerebral calcifications and cysts (LCC is a recently reported rare disease named ′Labrune syndrome′ after the first case was reported in 1996 by Labrune et al. Herein, we report a case of a 36-year-old man with mild right-sided weakness and seizures for 5 years. CT of brain revealed extensive calcification involving bilateral basal ganglia, right thalamus and bilateral deep cerebellar nuclei. A supratentorial cystic lesion with blood fluid level was seen in left occipitotemporal region. MRI examination revealed diffuse symmetric white matter hyperintensity suggesting leukoencephalopathy. On follow-up, patient reported improvement in the weakness and no further seizure episodes. However, follow-up of MRI revealed persistence of lesions. Differential diagnosis considered were parasitic infections (hydatid, cysticercosis, Coat′s plus disease and causes of diffuse cerebral calcification like Fahr′s disease and post-radiotherapy/chemotherapy. Serology for parasitic infections was negative. No history of radiotherapy or chemotherapy in the past could be elicited in the history. Another close differential is Coat′s plus disease which can mimic LCC pathologically.

    1. Clear kinetic differences between cytoplasmic and mitochondrial forms of type-I cerebral hexokinase were demonstrated from experiments performed under identical conditions on three (cytoplasmic, bound mitochondrial and solubilized mitochondrial) preparations of the enzyme. 2. Whereas the Michaelis constant for glucose (KmGlc) was consistent, that for MgATP2- (KmATP) was lower in the cytoplasmic than in the two mitochondrial preparations. The substrate dissociation constants (KsGlc and KsATP) were both higher in the cytoplasmic than in the mitochondrial preparations. A further difference in the substrate kinetic patterns was that KmATP=KmATP for the cytoplasmic enzyme, in contrast with the mitochondrial enzyme, where KmATP was clearly not equal to KsATP [Bachelard et al. (1971) Biochem. J. 123, 707-715]. 3. Dead-end inhibition produced by N-acetyl-glucosamine and by AMP also exhibited different quantitative kinetic patterns for the two enzyme sources. Both inhibitions gave Ki values similar or equal to those of Ki' for the cytoplasmic activity, whereas Ki was clearly not equal to Ki' for the mitochondrial activity. 4. All of these studies demonstrated the similarity of the two mitochondrial activities (particulate and solubilized), which were both clearly different from the cytoplasmic activity. 5. The analysis gives a practical example of our previous theoretical treatment on the derivation of true inhibition constants. 6. The results are discussed in terms of the function of cerebral hexokinases.

    Cerebral oximeters measure continuous cerebral oxygen saturation using near-infrared spectroscopy (NIRS) technology noninvasively. It has been involved into operating room setting to monitor oxygenation within patient's brain when surgeons are concerned that a patient's levels might drop. Recently, cerebral oxygen saturation has also been related with chronic cerebral vascular insufficiency (CCVI). Patients with CCVI would be benefited if there would be a wearable system to measure their cerebral oxygen saturation in need. However, there has yet to be a wearable wireless cerebral oximeter to measure the saturation in 24 hours. So we proposed to develop the wearable wireless cerebral oximeter. The mechanism of the system follows the NIRS technology. Emitted light at wavelengths of 740nm and 860nm are sent from the light source penetrating the skull and cerebrum, and the light detector(s) receives the light not absorbed during the light pathway through the skull and cerebrum. The amount of oxygen absorbed within the brain is the difference between the amount of light sent out and received by the probe, which can be used to calculate the percentage of oxygen saturation. In the system, it has one source and four detectors. The source, located in the middle of forehead, can emit two near infrared light, 740nm and 860nm. Two detectors are arranged in one side in 2 centimeters and 3 centimeters from the source. Their measurements are used to calculate the saturation in the cerebral cortex. The system has included the rechargeable lithium battery and Bluetooth smart wireless micro-computer unit.

  19. Cerebral microcirculation during experimental normovolaemic anaemia

    2016-02-01

    Full Text Available Anaemia is accepted amongst critically ill patients as an alternative to elective blood transfusion. This practice has been extrapolated to head injury patients with only one study comparing the effects of mild anaemia on neurological outcome. There are no studies quantifying microcirculation during anaemia. Experimental studies suggest that anaemia leads to cerebral hypoxia and increased rates of infarction, but the lack of clinical equipoise when testing the cerebral effects of transfusion amongst critically injured patients, supports the need of experimental studies. The aim of this study was to quantify cerebral microcirculation and the potential presence of axonal damage in an experimental model exposed to normovolaemic anaemia, with the intention of describing possible limitations within management practices in critically ill patients. Under non-recovered anaesthesia, six Merino sheep were instrumented using an intracardiac transeptal catheter to inject coded microspheres into the left atrium to ensure systemic and non-chaotic distribution. Cytometric analyses quantified cerebral microcirculation at specific regions of the brain. Amyloid precursor protein staining was used as an indicator of axonal damage. Animals were exposed to normovolaemic anaemia by blood extractions from the indwelling arterial catheter with simultaneous fluid replacement through a venous central catheter. Simultaneous data recording from cerebral tissue oxygenation, intracranial pressure and cardiac output was monitored. A regression model was used to examine the effects of anaemia on microcirculation with a mixed model to control for repeated measures. Homogeneous and normal cerebral microcirculation with no evidence of axonal damage was present in all cerebral regions, with no temporal variability, concluding that acute normovolaemic anaemia does not result in short term effects on cerebral microcirculation in the ovine brain.

    Full Text Available MRI, done later in life, in two patients with infantile hemiplegia syndrome showed significant volume loss in the cerebellar hemisphere contralateral to the side of the affected cerebrum. The cerebellar volume loss seemed to correlate with the degree of volume loss in the contralateral cerebral hemisphere. These observations provide morphological evidence of the phenomenon of crossed cerebral-cerebellar diaschisis (CCD. Functional neuroimaging studies in support of the concept of CCD has been critically reviewed.

    Purpose: The purpose of our study is to evaluate the efficacy of cerebral perfusion single photon emission computerized tomography (SPECT) in patients with transient ischemic attack (TIA). Methods: Thirty-seven patients with TIA were collected for study. All patients had transient focal neurological symptoms or signs with complete recovery within 24 h after onset. The patients underwent cerebral perfusion SPECT between 6 h and 11 days after onset, with 10 cases performed within 24 h (group A), nine cases performed between 1 and 3 days (group B), 11 cases performed between 3 and 5 days (group C), and seven cases performed after more than 5 days (group D). A semi-quantitative method was used for analyzing the SPECT data, and the difference ratios between lesion side and contralateral normal side were calculated on each pair of regions of interest. Results: In total, 78.4% (29/37) of patients had reduced perfusion in the cerebral cortical regions or deep nuclei, and the regions with reduced perfusion corresponded with clinical presentations of the patients. The abnormal rate with reduced perfusion was 90.0% in group A, 77.8% in group B, 72.7% in group C and 71.4% in group D. Cross cerebellar diaschisis (CCD) was present in seven patients, and all of the primary cerebral perfusion defects of these patients were located at the territory of left or right middle cerebral artery. Conclusion: Cerebral perfusion SPECT is a potential tool to detect cerebral perfusion defects and CCD in patients with TIA. Although the perfusion defect may persist more than 5 days after onset, we suggest cerebral perfusion SPECT should be performed as soon as possible.

    We report serial neuroradiological studies in a patient with focal cerebritis in the head of the left caudate nucleus. On the day after the onset of symptoms, CT showed an ill-defined low density lesion. The lack of contrast enhancement appeared to be the most important finding for differentiating focal cerebritis from an encapsulated brain abscess or a tumour. MRI two days later revealed the centre of the lesion to be of slightly low intensity on T1-weighted inversion recovery (IR) images and very low intensity on T2-weighted spin echo images, which appeared to correspond to the early cerebritis stage of experimentally induced cerebritis and brain abscess. Ten days after the onset of symptoms, CT revealed a thin ring of enhancement in the head of the caudate nucleus, and a similar small ring was seen in the hypothalamus 16 days after the onset, corresponding to the late cerebritis stage. MRI nine days later revealed ill-defined high signal lesions within the involved area on the T1-weighted IR images. To our knowledge, this is the first published MRI documentation of the early cerebritis stage developing into an encapsulated brain abscess. The mechanisms underlying of these radiographic changes are discussed. (orig.)

Materials and Methods: The study conducted on 136 cases of ruptured cerebral aneurysms between 1995-2000 confirmed by means of 4-vessel cerebral angiography to get an insight to racial, geographic and environmental factors predisposing to the occurrence of subarachnoid hemorrhage and aneurysm formation. Results: The data analysis revealed the following results: 58% of the population comprised of male and 42% female with a mean age of 46 years. 89% of the aneurysms were found in the anterior circulation and 11% occurred in the posterior cerebral circulation. The most common site in both the sexes was the anterior communicating artery. 9.6% of the patients displayed two separate aneurysms. 5.2% of the aneurysms were found to be giant aneurysms and 3% of the patients had fusiform aneurysms. Conclusion: The low average age, a predilection in male population and the prevalence of aneurysms at carotid and middle cerebral artery bifurcation and the distal branches of anterior cerebral artery and a higher incidence of anterior communicating artery in women were the findings observed in this study.

  5. [Platelets, atherothrombosis, antiplatelet drugs and cerebral ischemia].

    Bousser, Marie-Germaine

    2013-02-01

    Platelets play a much more important role in myocardial ischemia than in cerebral ischemia, because atherothrombosis - the underlying cause of the vast majority of myocardial infarcts - is responsible for only 25-30% of cerebral infarcts. Aspirin is the only effective antiplatelet drug for primary prevention of ischemic events, especially those affecting the heart. For secondary prevention of cerebral infarction, clopidogrel and the combination of aspirin with extended-release dipyridamole are both marginally better than aspirin alone, but aspirin remains the gold standard worldwide because of its remarkable cost/benefit/tolerability ratio. The clopidogrel-aspirin combination is to be avoided because of the risk of hemorrhage, particularly in the brain and gastrointestinal tract. Revascularization strategies and the choice of antiplatelet drugs for the acute phase of myocardial and cerebral ischemia are very different, consisting of endovascular treatment and aggressive platelet inhibition for coronary infarcts, versus intravenous thrombolysis and / or aspirin for cerebral infarcts. None of the new antiplatelet drugs used in acute coronary syndromes has so far been studied in acute cerebral ischemia. PMID:24919368

    BACKGROUND: Several studies have demonstrated that sustained cognitive tasks can induce cognitive fatigue and that the mean cerebral blood flow velocity changes in some cerebral regions during cerebral fatigue. OBJECTIVE: To dynamically monitor the changes in mean cerebral blood flow velocity in different brain regions of high performance fighter pilots during mental arithmetic tasks and consecutive performance tasks. DESIGN, TIME AND SETTING: The present neurophysiological trial, based on controlled observation, was performed at the Laboratory of Neurophysiology, Institute of Aviation Medicine, Air Force of China between January 2003 and December 2005. PARTICIPANTS: Forty-five males, high performance fighter pilots, averaging (27.6 ± 2.5) years, were recruited for this study. METHODS: The mean cerebral blood flow velocity in the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery of subjects was dynamically tested using transcranial Doppler during 5- hour mental arithmetic tasks and during 5- hour consecutive performance tasks. The neurobehavioral ability index was analyzed throughout each trial according to the number of correct responses, false responses, and lost responses. Simultaneously, cerebral cognitive fatigue-induced lethargy was assessed by the Stanford Sleepiness Scale. MAIN OUTCOME MEASURES: Changes in mean cerebral blood flow velocity in the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery; neurobehavioral ability index of mental arithmetic and consecutive performance tasks; Stanford Sleepiness Scale scores. RESULTS: During mental arithmetic tasks, the mean cerebral blood flow velocity in the anterior cerebral artery increased during hour 2 and decreased after hour 4. There was no significant change in mean cerebral blood flow velocity in the middle cerebral artery and posterior cerebral artery. During hour 4, cerebral cognitive fatigue was observed and, simultaneously, Stanford Sleepiness

    We measured cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO2) during light sleep (stage 2) in 8 young healthy volunteers using the Kety-Schmidt technique with 133Xe as the inert gas. Measurements were performed during wakefulness and light sleep as verified by standard...... polysomnography. Unlike our previous study in man showing a highly significant 25% decrease in CMRO2 during deep sleep (stage 3-4) we found a modest but statistically significant decrease of 5% in CMRO2 during stage 2 sleep. Deep and light sleep are both characterized by an almost complete lack of mental activity....... They differ in respect of arousal threshold as a stronger stimulus is required to awaken a subject from deep sleep as compared to light sleep. Our results suggest that during non-rapid eye movement sleep cerebral metabolism and thereby cerebral synaptic activity is correlated to cerebral readiness rather than...

  18. The effect of herbs on cerebral energy metabolism in cerebral ischemia-reperfusion mice

    2001-01-01

    @@Vascular dementia is one of the most familiar types of senile dementia. Over the past few years, the research on the damage of cerebral tissues after ischemia has become a focus. The factors and mechanism of cerebral tissue damage after ischemia are very complex. The handicap of energy metabolism is regarded as the beginning factor which leads to the damage of neurons, but its dynamic changes in ischemic area and its role during the process of neuronal damage are not very clear. There are few civil reports on using 31 P nuclear magnetic resonance instrument to explore the changes of cerebral energy metabolism in intravital animals. After exploring the influence of herbs on cerebral energy metabolism in ischemia-reperfusion mice, we came to the conclusion that herbs can improve the cerebral energy metabolism in ischemia-reperfusion mice.

  19. Having another look at cerebral palsy: Current definitions and classification systems

    Full Text Available Although many music therapists work with clients with cerebral palsy, this diagnostic term has a low profile in current music therapy literature. This is especially the case when the focus of intervention is not in the realm of physical functioning. The frequently co-occurring disorders in sensation, cognition, communication, perception, and behaviour are often the focus of music therapy intervention, particularly with children and adults with severe and multiple disability. Current perspectives on the care and participation of children and adults with cerebral palsy, including motor classification scales, can be useful for research and clinical reporting. These scales are explained and examined, as is the effect of the motor impairments of cerebral palsy on active music therapy methods. Clinical vignettes illustrate the effect of different levels of functional fine motor skills as assessed by the Manual Ability Classification System (Eliasson, A.C., et al, 2006 on musical interaction. Including the term “cerebral palsy” in clinical reports and research also has implications for awareness of music therapy in the wider community.

    Orthostatic intolerance remains a problem upon return to Earth from the microgravity environment of spaceflight. A variety of conditions including hypovolemia, cerebral vasoconstriction, cerebral or peripheral vascular disease, or cardiac arrhythmias may result in syncope if the person remains upright. Current research indicates that there is a greater dependence on visual and somatosensory information at the beginning of space flight with a decreased otolith gain during prolonged space flight (Herault et al., 2002). The goal of the research is to further our understanding of the fundamental adaptive homeostatic mechanisms involved in gravity related changes in cardiovascular and postural function. Cardiovascular, cerebrovascular, and postural sensory motor control systems in male and female participants before, during, and after exposure to graded levels of hyper-G were investigated. Hypotheses: 1) Activation of skeletal muscle pump will be directly related to the degree of orthostatic stress. 2) Simultaneous measurement of heart rate, blood pressure and postural sway will predict cardio-postural stability. Blood pressure and heart rate (means and variability), postural sway, center of pressure (COP), baroreflex function, calf blood flow, middle cerebral artery blood flow, non-invasive intracranial pressure measurements, and two-breath CO2 were measured. Results from the study will be used to provide an integrated insight into mechanisms of cardio-postural control and cerebral autoregulation, which are important aspects of human health in flights to Moon, Mars and distant planets.

    Most of cerebral aneurysms (CAs) are incidentally discovered without any neurological symptoms and the risk of rupture of CAs is relatively higher in Japanese population. The goal of treatments for patients with CAs is complete exclusion of the aneurysmal rupture risk for their lives. Since two currently available major treatments, microsurgical clipping and endovascular coiling, have inherent incompleteness to achieve cure of CAs with some considerable treatment risks, and there is no effective surgical or medical intervention to inhibit the formation of CAs in patients with ruptured and unruptured CAs, new treatment strategies with lower risk and higher efficacy should be developed to prevent the formation, growth, and rupture of CAs. Preemptive medicine for CAs should be designed to prevent or delay the onset of symptoms from CAs found in an asymptomatic state or inhibit the de novo formation of CAs, but we have no definite methods to distinguish rupture-prone aneurysms from rupture-resistant ones. Recent advancements in the research of CAs have provided us with some clues, and one of the new treatment strategies for CAs will be developed based on the findings that several inflammatory pathways may be involved in the formation, growth, and rupture of CAs. Preemptive medicine for CAs will be established with specific biomarkers and imaging modalities which can sensor the development of CAs. PMID:27053328

  4. The hip in cerebral palsy.

    Orthopedic surgery can alleviate the hip flexion, adduction, and medial rotation deformities of the hip and improve the function and appearance of gait. To accomplish this, however, careful examination and prudence in the operative procedure to avoid overdoing and overcorrecting are important. Orthopedic surgery can prevent subluxation and dislocation of the hip before the age of seven years, and consequently repetitive radiographic examinations of the hip in children who have spastic paralysis of the hip musculature should be a routine procedure. Subluxation and dislocation of the hip, when established, can be successfully treated with orthopedic surgical procedures. Physicians must keep in mind that the spastic paralysis of cerebral palsy originates in the brain, and therefore the spasticity cannot be eliminated. The best that can be done is to weaken or remove some muscles as deforming forces and to achieve compromises for continued function. The goal should be optimal independence for the child and adolescent during development, and freedom from pain with deteriorating function due to degenerative arthritis in the adult. PMID:7360505

  5. Clinical presentation of cerebral aneurysms

    International Nuclear Information System (INIS)

    Presentation of a cerebral aneurysm can be incidental, discovered at imaging obtained for unrelated causes, can occur in the occasion of imaging obtained for symptoms possibly or likely related to the presence of an unruptured aneurysm, or can occur with signs and symptoms at the time of aneurismal rupture. Most unruptured intracranial aneurysms are thought to be asymptomatic, or present with vague or non-specific symptoms like headache or dizziness. Isolated oculomotor nerve palsies, however, may typically indicate the presence of a posterior circulation aneurysm. Ruptured intracranial aneurysms are by far the most common cause of non-traumatic subarachnoid hemorrhage and represent a neurological emergency with potentially devastating consequences. Subarachnoid hemorrhage may be easily suspected in the presence of sudden and severe headache, vomiting, meningism signs, and/or altered mental status. However, failure to recognize milder and more ambiguous clinical pictures may result in a delayed or missed diagnosis. In this paper we will describe the clinical spectrum of unruptured and ruptured intracranial aneurysms by discussing both typical and uncommon clinical features emerging from the literature review. We will additionally provide the reader with descriptions of the underlying pathophysiologic mechanisms, and main diagnostic pitfalls

  6. Cerebral CT of ischaemic lesions

    1981-11-25

    The diagnosis of stroke must first be established by clinical examination. CT has proved useful for confirmation of the diagnosis and provides a global intracranial picture of morphological changes in cerebral vascular diseases. A hemorrhage can be recognized with certainty at the first CT examination as the cause of the stroke, but in the detection of a lesion due to ischemia an important role is played by the correct choice of the time of examination, and in some cases also of the check-up with contrast medium. The differential diagnosis between infarct in the acute stage and encephalitis or gliomas of low-grade malignity can be difficult. A decision can often only be made after a series of examinations. Postmalacial conditions are often difficult to differentiate from defects due to other causes, such as hemorrhage, head injury, postoperative states and after encephalitis. A knowledge of the anamnesis and the clinical findings is indispensable for CT evaluation. In assessing the prognosis before vascular surgery on the extracranial brain-supplying vessels the performance of a CT examination should be advised. A warning is given against the use of CT as a screening method.

    With each heartbeat, pressure wave (PW) propagates from aorta toward periphery. In cerebral circulation, at the level of circle of Willis (CW), four arteries and four PWs converge. Since the interference is an elemental property of the wave, PWs interfere at the level of CW. We hypothesize that the asymmetry of brain-supplying arteries (that join to form CW) creates phase difference between the four PWs that interfere at the level of CW and reduce downstream cerebral pulsatility. To best of our knowledge, the data about the sequence of PWs' arrival into the cerebral circulation is lacking. Evident imperfect bilateral symmetry of the vessels results with different path length of brain-supplying arteries, hence, PWs should arrive into the head at different times. The probabilistic calculation shows that asynchronous arrival is more probable than synchronous. The importance of PWs for the cerebral circulation is highlighted by the observation that barotrauma protection mechanisms are more influenced by the crest of PW (pulse pressure) than by the mean arterial pressure. In addition, an increased arterial pulsatility is associated with several brain pathologies. We created simple computational models of four converging arteries and found that asynchronous arrival of the PWs results with lower maximum pressure, slower rate of pressure amplification and lower downstream pulsatility. In analogy, the asynchronous arrival of the pressure waves into the cerebral circulation should decrease blood flow pulsatility and lower transmission of kinetic energy on arterial wall. We conclude that asynchronous arrival of PWs into the cerebral circulation influences cerebral hemodynamics and represents a physiological necessity. PMID:26277658

    Full Text Available INTRODUCTION: Cerebral palsy ( CP is a group of permanent movement disorders that appear in early childhood. Preterm birth is the birth of baby before 37 completed weeks, a full term birth is birth at 37 to 42 weeks of gestation . AIM: To show the extent of association of preterm deliveries as a risk factor in development of cerebral palsy. MATERIALS AND METHODS: This r etrospective cohort study was conducted by eliciting history from the mothers of 99 cerebral palsy children who w ere treated in Rani Chandra Mani Devi Hospital, Visakhapatnam, Andhra Pradesh, India. De tailed history was taken from the mothers of 99 cerebral palsy children who were treated in this hospital. History regarding the period of gestation at which the child was born (preterm or full term, any previous history of pre - term delivery or abortions, was obtained from the mothers and the data analyzed . RESULTS: From this study it was observed the proportional association of pre - term births to cerebral palsy is 33 out 99 i.e., about 33.33%, Of these 33 cerebral palsy children highest association being with birth at 28 wks gestation (51 %. This study also shows th at the mothers with a previous history of preterm delivery have 14.4 times higher risk of subsequent pre term delivery; those with previous history of abortions have 5.7 times risk of pre - term delivery than mothers without such history. CONCLUSION: From th is study it was concluded that the pre - term birth plays a major role as a risk factor in the development of cerebral palsy with mothers having previous pre term delivery and previous abortions adding further to this risk.

    The protein expressions of neurotrophic factors can be enhanced by low-intensity pulsed ultrasound (LIPUS) stimulation in the brain. The purpose of this study was to demonstrate the protective effect of LIPUS stimulation against aluminum-induced cerebral damage in Alzheimer's disease rat model. LIPUS was administered 7 days before each aluminum chloride (AlCl3) administration, and concomitantly given with AlCl3 daily for a period of 6 weeks. Neurotrophic factors in hippocampus were measured by western blot analysis. Behavioral changes in the Morris water maze and elevated plus maze were examined in rats after administration of AlCl3. Various biochemical analyses were performed to evaluate the extent of brain damages. LIPUS is capable of prompting levels of brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), and vascular endothelial growth factor (VEGF) in rat brain. AlCl3 administration resulted in a significant increase in the aluminum concentration, acetylcholinesterase activity and beta-amyloid (Aβ) deposition in AlCl3 treated rats. LIPUS stimulation significantly attenuated aluminum concentration, acetylcholinesterase activity, Aβ deposition and karyopyknosis in AlCl3 treated rats. Furthermore, LIPUS significantly improved memory retention in AlCl3-induced memory impairment. These experimental results indicate that LIPUS has neuroprotective effects against AlCl3-induced cerebral damages and cognitive dysfunction.

    Progressive supranuclear palsy (PSP) is a Parkinson-plus syndrome characterized clinically by supranuclear ophthalmoplegia, pseudobulbar palsy, axial rigidity, bradykinesia, postural instability and dementia. Presence of dementia and lack of cortical histopathology suggest the derangement of cortical function by pathological changes in subcortical structures in PSP, which is supported by the pattern of behavioral changes and measurement of brain metabolism using positron emission tomography. This study was done to examine whether there are specific changes of regional cerebral perfusion in PSP and whether there is a correlation between severity of motor abnormaility and degree of changes in cerebral perfusion. We measured regional cerebral perfusion indices in 5 cortical and 2 subcortical areas in 6 patients with a clinical diagnosis of PSP and 6 healthy age and sex matched controls using Tc-99m-HMPAO SPECT. Compared with age and sex matched controls, only superior frontal regional perfusion index was significantly decreased in PSP (p<0.05). There was no correlation between the severity of the motor abnormality and any of the regional cerebral perfusion indices (p>0.05). We affirm the previous reports that perfusion in superior frontal cortex is decreased in PSP. Based on our results that there was no correlation between severity of motor abnormality and cerebral perfusion in the superior frontal cortex, nonmotoric symptoms including dementia needs to be looked at whether there is a correlation with the perfusion abnormality in superior frontal cortex

    Full Text Available Background. Nontraumatic cerebral air embolism cases are rare. We report a case of an air embolism resulting in cerebral infarction related to angioinvasive cavitary aspergillosis. To our knowledge, there have been no previous reports associating these two conditions together. Case Presentation. A 32-year-old female was admitted for treatment of acute lymphoblastic leukemia (ALL. Her hospital course was complicated by pulmonary aspergillosis. On hospital day 55, she acutely developed severe global aphasia with right hemiplegia. A CT and CT-angiogram of her head and neck were obtained demonstrating intravascular air emboli within the left middle cerebral artery (MCA branches. She was emergently taken for hyperbaric oxygen therapy (HBOT. Evaluation for origin of the air embolus revealed an air focus along the left lower pulmonary vein. Over the course of 48 hours, her symptoms significantly improved. Conclusion. This unique case details an immunocompromised patient with pulmonary aspergillosis cavitary lesions that invaded into a pulmonary vein and caused a cerebral air embolism. With cerebral air embolisms, the acute treatment option differs from the typical ischemic stroke pathway and the provider should consider emergent HBOT. This case highlights the importance of considering atypical causes of acute ischemic stroke.

  13. Time-varying modeling of cerebral hemodynamics.

    2014-03-01

    The scientific and clinical importance of cerebral hemodynamics has generated considerable interest in their quantitative understanding via computational modeling. In particular, two aspects of cerebral hemodynamics, cerebral flow autoregulation (CFA) and CO2 vasomotor reactivity (CVR), have attracted much attention because they are implicated in many important clinical conditions and pathologies (orthostatic intolerance, syncope, hypertension, stroke, vascular dementia, mild cognitive impairment, Alzheimer's disease, and other neurodegenerative diseases with cerebrovascular components). Both CFA and CVR are dynamic physiological processes by which cerebral blood flow is regulated in response to fluctuations in cerebral perfusion pressure and blood CO2 tension. Several modeling studies to date have analyzed beat-to-beat hemodynamic data in order to advance our quantitative understanding of CFA-CVR dynamics. A confounding factor in these studies is the fact that the dynamics of the CFA-CVR processes appear to vary with time (i.e., changes in cerebrovascular characteristics) due to neural, endocrine, and metabolic effects. This paper seeks to address this issue by tracking the changes in linear time-invariant models obtained from short successive segments of data from ten healthy human subjects. The results suggest that systemic variations exist but have stationary statistics and, therefore, the use of time-invariant modeling yields "time-averaged models" of physiological and clinical utility.

    International Nuclear Information System (INIS)

    In-vivo proton and phosphorus magnetic resonance spectroscopy was used to detect changes in cerebral metabolism during ischemia and other types of metabolic stress. Magnetic resonance imaging was performed in an animal model to observe morphological alterations during focal cerebral ischemia. Spectroscopy was performed in animal models with global ischemia, in volunteers during hyperventilation and pharmaco-logically altered cerebral perfusion, and in patients with acute and prolonged focal cerebral ischemia.

    Cerebral edema is a life-threatening complication of diabetic ketoacidosis (DKA) which may predominantly develop in pediatric cases during the management of DKA.. Symptomatic cerebral edema in children is rarely detected at admission, before initiation of the treatment. Cerebral edema associated with DKA is extremely rare in adults. Here, we report an adult patient with DKA who presented with symptomatic cerebral edema. Turk Jem 2009; 13: 16-8

    Post-ischemic hyperglycemia exacerbates the development of cerebral ischemia. To elucidate this exacerbation mechanism, we focused on sodium-glucose transporter (SGLT) as a mediator that lead hyperglycemia to cerebral ischemia. SGLT transport glucose into the cell, together with sodium ion, using the sodium concentration gradient. We have previously reported that suppression of cerebral SGLT ameliorates cerebral ischemic neuronal damage. However, detail relationship cerebral between SGLT and post-ischemic hyperglycemia remain incompletely defined. Therefore, we examined the involvement of cerebral SGLT on cerebral ischemic neuronal damage with or without hyperglycemic condition. Cell survival rate of primary cultured neurons was assessed by biochemical assay. A mouse model of focal ischemia was generated using a middle cerebral artery occlusion (MCAO). Neuronal damage was assessed with histological and behavioral analyses. Concomitant hydrogen peroxide/glucose treatment exacerbated hydrogen peroxide alone-induced cell death. Although a SGLT family-specific inhibitor, phlorizin had no effect on developed hydrogen peroxide alone-induced cell death, it suppressed cell death induced by concomitant hydrogen peroxide/glucose treatment. α-MG induced a concentration-dependent and significant decrease in neuronal survival. PHZ administered on immediately after reperfusion had no effect, but PHZ given at 6h after reperfusion had an effect. Our in vitro study indicates that SGLT is not involved in neuronal cell death in non-hyperglycemic condition. We have already reported that post-ischemic hyperglycemia begins to develop at 6h after MCAO. Therefore, current our in vivo study show post-ischemic hyperglycemic condition may be necessary for the SGLT-mediated exacerbation of cerebral ischemic neuronal damage.

    Renovascular hypertensive rats (RHRs) were developed using the 2-kidney, 2-clip method. All RHRs at 10 weeks displayed high permeability of the cerebral surface blood vessels. Vascular casts of the RHRs showed that the vascular network was sparse. The arterioles of the RHRs at 10 weeks had smaller lumen diameters, but thicker vessel walls with hyalinosis formation compared with control animals. The endothelial cell membrane appeared damaged, and microthrombus formed. After ischemia, the infarction size was larger in RHRs than in control animals. These results suggest that cerebral arterioles in RHRs underwent structural remodeling. High blood pressure may aggravate the severity of brain injury in cerebral ischemia and affect the recovery of ischemia.

  8. Neuropsychological Effects of Cerebral Amyloid Angiopathy.

    Schrag, Matthew; Kirshner, Howard

    2016-08-01

    Cerebral amyloid angiopathy is a condition of the cerebral arterioles and to a lesser extent capillaries and veins, wherein beta-amyloid is deposited. In arterioles, this preferentially targets vascular smooth muscle cells and in the later stages undermines the stability of the vessel. This condition is frequently comorbid with Alzheimer's disease and its role in cognitive impairment and dementia is a topic of considerable recent research. This article reviews recent literature which confirms that CAA independently contributes to cognitive impairment by potentiating the neurodegeneration of Alzheimer's disease, by predisposing to microhemorrhagic and microischemic injury to the brain parenchyma, and by interfering with the autoregulation of CNS blood flow. In this review, we discuss the clinical presentation of cerebral amyloid angiopathy, with a focus on the neuropsychological manifestations of this vasculopathy. PMID:27357378

    The method of transcranial electrostimulation (TCES) has been used for treatment of 68 patients with chronic cerebral vascular insufficiency, stages I and II. A treatment course included 7 daily procedures. The influence of TCES was evaluated clinically, by EEG, transcranial ultrasonic Doppler study and hemodynamic indices in arteries and veins as well as by expression of trait and state anxiety. All the parameters were compared to those of the control group which was treated using conventional methods. TCES resulted in normalization of cerebral vascular reactivity, a decrease of venous circulation disturbances, positive influence on cerebral blood flow and EEG parameters, that corresponded to global improvement of the patients' state, regress of cephalgic syndrome and reduction of trait and state anxiety. The method is simple and safety and can be recommended for wide application including outpatient setting.

    Increased natriuresis is a frequent situation after subarachnoid haemorrhage (SAH). It may be responsible for hyponatremia, which can be dangerous in case of severe hypo-osmolarity or hypovolemia. Inappropriate secretion of antidiuretic hormone or cerebral salt wasting syndrome (CSWS) have been incriminated for hyponatremia after SAH, but it remains difficult to distinguish between both syndromes. There are many explanations for increased natriuresis after SAH, depending on the level of blood pressure, the volemia, and the presence or not of natriuretic peptides. The cerebral insult and the treatments, which are done to fight against elevated intracranial pressure or vasospasm, can modify any of these parameters. So it appears that the word "cerebral" in CSWS is probably not a good term and it would be better to talk about appropriate or non-appropriate natriuretic response. Corticoïds or urea can be useful for controlling hypernatriuresis.

    In this study, we hypothesized that total flavonoid of Litsea coreana leve (TFLC) protects against focal cerebral ischemia/reperfusion injury. TFLC (25, 50, 100 mg/kg) was administered oral y to a rat model of focal ischemia/reperfusion injury, while the free radical scavenging agent, edaravone, was used as a positive control drug. Results of neurological deficit scoring, 2,3,5-triphenyl tetrazolium chloride staining, hematoxylin-eosin staining and biochemical tests showed that TFLC at different doses significantly al eviated cerebral ischemia-induced neurological deficits and histopathological changes, and reduced infarct volume. Moreover, it suppressed the increase in the levels of nitrates plus nitrites, malondialdehyde and lactate dehydrogenase, and it diminished the reduction in gluta-thione, superoxide dismutase and catalase activities induced by cerebral ischemia/reperfusion in-jury. Compared with edaravone, the protective effects of TFLC at low and medium doses (25, 50 mg/kg) against cerebral ischemia/reperfusion injury were weaker, while the protective effects at high dose (100 mg/kg) were similar. Our experimental findings suggest that TFLC exerts neuroprotective effects against focal cerebral ischemia/reperfusion injury in rats, and that the effects may be asso-ciated with its antioxidant activities.

    Current understanding of cerebral FDG uptake during childhood originates from a small number of studies in patients with neurological abnormalities. Our aim was to describe cerebral FDG uptake in a dataset of FDG PET scans in children more likely to represent a normal population. We reviewed cerebral FDG PET scans in children up to 16 years of age with suspected/proven extracranial malignancies and the following exclusions: central nervous system metastases, previous malignancies, previous chemotherapy or radiotherapy, development of cerebral metastases during therapy, neurological conditions, taking antiepileptic medication or medications likely to interfere with cerebral metabolism, and general anaesthesia within 24 h. White matter, basal ganglia, thalamus and the cerebellar cortex were analysed using regional SUV{sub max}, and the cerebral cortex, basal ganglia, thalamus and cerebellum were analysed using a regional relative uptake analysis in comparison to maximal cortical uptake. Scans from 30 patients (age range 11 months to 16 years, mean age 10 years 5 months) were included. All regions showed increasing SUV{sub max} with age. The parietal, occipital, lateral temporal and medial temporal lobes showed lower rates of increasing FDG uptake causing changing patterns of regional FDG uptake during childhood. The cortical regions showing the most intense uptake in early childhood were the parietal and occipital lobes. At approximately 7 years of age these regions had relatively less uptake than the frontal lobes and at approximately 10 years of age these regions had relatively less uptake than the thalamus. Relative FDG uptake in the brain has not reached an adult pattern by 1 year of age, but continues to change up to 16 years of age. The changing pattern is due to different regional rates of increasing cortical FDG uptake, which is less rapid in the parietal, occipital and temporal lobes than in the frontal lobes. (orig.)

    Full Text Available Resumen El objetivo de este artículo es estimar los AVP atribuibles al consumo de alcohol en la Ciudad de México durante 2006 – 2012. Se utilizaron las estadísticas vitales de mortalidad del INEGI atribuibles al consumo de alcohol para obtener los AVP, se obtuvieron ademas promedios de edad de muerte respecto a intervalos de edad por sexo. Se estimaron 168,607 AVP, con una pérdida promedio de 18.32 años para los hombres y 17.54 en mujeres. Se encontró una mayor proporción de AVP en hombres que en mujeres. De acuerdo a la CIE-10 se observó que las enfermedades del hígado atribuibles al alcohol, aportan más del 80% de los AVP al total. Existe una tendencia cíclica en los AVP entre 2006 a 2012. Los AVP atribuibles al alcohol apuntan a que el consumo es un problema de salud pública que implican pérdidas en la productividad y costos económicos, mientras la baja en los AVP podría ser explicada por una disminución en el ingreso provocada por la crisis económica de 2008 al igual que el aumento por la mejoría en el 2012.

    Cuéllar-Herrera, M.; Rocha, L.

    2003-09-01

    Electrical stimulation of the nervous tissue has been proposed as a method to treat some neurological disorders, such as epilepsy. Epileptic seizures result from excessive, synchronous, abnormal firing patterns of neurons that are located predominantly in the cerebral cortex. Many people with epilepsy continue presenting seizures even though they are under regimens of antiepileptic medications. An alternative therapy for treatment resistant epilepsy is cerebral electrical stimulation. The present study is focused to review the effects of different types of electrical stimulation and specifically changes in amino acids.

  10. Experimental thrombolysis of middle cerebral artery thromboemboli

    International Nuclear Information System (INIS)

    Since the majority of ischaemic cerebral infarcts is caused by thromboemboli, we determined the benefit of firbrinolytic therapy in acute stroke. Thromboemboli were induced in the middle cerebral artery of 21 dogs. Urokinase was started at different time intervals after infarction (1, 3 and 5 hours) at a rate of 1000 IU/kg/min. Angiographically controlled thrombolysis was achieved in all 15 treated cases, whereas in the control group (n=6) no case of recanalisation was observed. Systemic fibrinolysis occurred in all cases. Postmortem examinations of the brains showed no intracerebral haemorrhages. Our findings indicate the urokinase treatment may be of value in acute ischaemic stroke. (orig.)

    2015-12-01

    We report two cases of neuromyelitis optica patients with progressive cerebral atrophy. The patients exhibited characteristic clinical features, including elderly onset, secondary progressive tetraparesis and cognitive impairment, abnormally elevated CSF protein and myelin basic protein levels, and extremely highly elevated serum anti-AQP-4 antibody titer. Because neuromyelitis optica pathology cannot switch from an inflammatory phase to the degenerative phase until the terminal phase, neuromyelitis optica rarely appears as a secondary progressive clinical course caused by axonal degeneration. However, severe intrathecal inflammation and massive destruction of neuroglia could cause a secondary progressive clinical course associated with cerebral atrophy in neuromyelitis optica patients.

    Subarachnoid hemorrhage is the most common cause of cerebral salt wasting syndrome. There are few reports of this condition in infectious meningitis. We describe a patient with hyponatremia and bacterial meningitis. Hyponatremia rapidly improved after administration of sodium chloride. The purpose of this report is to alert clinicians to the fact that hyponatremic patients with central nervous system disease do not necessarily have a syndrome of inappropriate secretion of antidiuretic hormone (SIADH), but may have cerebral salt wasting syndrome. By contrast with SIADH, the treatment requires saline administration.

    Constant cerebral blood flow (CBF) is vital to human survival. Originally thought to receive steady blood flow, the brain has shown to experience increases in blood flow during exercise. Although increases have not consistently been documented, the overwhelming evidence supporting an increase may be a result of an increase in brain metabolism. While an increase in metabolism may be the underlying causative factor for the increase in CBF during exercise, there are many modulating variables. Arterial blood gas tensions, most specifically the partial pressure of carbon dioxide, strongly regulate CBF by affecting cerebral vessel diameter through changes in pH, while carbon dioxide reactivity increases from rest to exercise. Muscle mechanoreceptors may contribute to the initial increase in CBF at the onset of exercise, after which exercise-induced hyperventilation tends to decrease flow by pial vessel vasoconstriction. Although elite athletes may benefit from hyperoxia during intense exercise, cerebral tissue is well protected during exercise, and cerebral oxygenation does not appear to pose a limiting factor to exercise performance. The role of arterial blood pressure is important to the increase in CBF during exercise; however, during times of acute hypotension such as during diastole at high-intensity exercise or post-exercise hypotension, cerebral autoregulation may be impaired. The impairment of an increase in cardiac output during exercise with a large muscle mass similarly impairs the increase in CBF velocity, suggesting that cardiac output may play a key role in the CBF response to exercise. Glucose uptake and CBF do not appear to be related; however, there is growing evidence to suggest that lactate is used as a substrate when glucose levels are low. Traditionally thought to have no influence, neural innervation appears to be a protective mechanism to large increases in cardiac output. Changes in middle cerebral arterial velocity are independent of changes in

    In the treatment of brachial plexus injury, nerves that are functionally less important are trans-ferred onto the distal ends of damaged crucial nerves to help recover neuromuscular function in the target region. For example, intercostal nerves are transferred onto axillary nerves, and accessory nerves are transferred onto suprascapular nerves, the phrenic nerve is transferred onto the musculocutaneous nerves, and the contralateral C7 nerve is transferred onto the median or radial nerves. Nerve transfer has become a major method for reconstructing the brachial plexus after avulsion injury. Many experiments have shown that nerve transfers for treatment of brachi-al plexus injury can help reconstruct cerebral cortical function and increase cortical plasticity. In this review article, we summarize the recent progress in the use of diverse nerve transfer methods for the repair of brachial plexus injury, and we discuss the impact of nerve transfer on cerebral cortical plasticity after brachial plexus injury.

    The energy supplied to the brain by metabolic substrate is largely utilized for maintaining synaptic transmission. In this regulation cerebral blood flow and glucose consumption is tightly coupled as well in the resting condition as during activation. Quantification of cerebral blood flow...... and metabolism was originally performed using the Kety-Schmidt method and this method still represent the gold standard by which subsequent methods have been evaluated. However, in its classical setting, the method overestimates cerebral blood flow. Studies of metabolic changes during activation must take...... difficulties due to limitation in resolution and partial volume effects. In contrast to the tight coupling between regional glucose metabolism and cerebral blood flow, there is an uncoupling between flow and oxygen consumption as the latter only increases to a limited extend. The excess glucose uptake is thus...

    We report a case of cerebral toxoplasmosis in a patient with stage IV C[sub 1] AIDS who presented hyperdense CT images 13 days after beginning antitoxoplasma treatment. These lesions could be caused by calcifications or blood. The attenuation values lead us to believe that they are calcium. Intracranial calcification in adult cerebral toxoplasmosis is an uncommon finding. Its presence in AIDS patients should not suggest any etiology other than toxoplasmosis. (Author) 16 refs.

  11. Measurement of cerebral circulation time in man

    International Nuclear Information System (INIS)

    A simple, inexpensive method for measuring the cerebral circulation time (CCT) was developed. The CCT was considered to be equal to the time that an intravenously injected bolus of sodium pertechnetate Tc 99m took to go from the subclavian artery to the posterior venous confluence. The dilution curves were externally recorded at these two vessels. Particular attenion was given to the curve treatment. The computer programmes were specially conceived in order to detect and, if possible, correct the experimental curve defects. Several reliability criteria were also defined in order to test the validity of each measurement. From a physiological point of view, the CCT is equal to the ratio of the global cerebral blood volume to the global cerebral blood flow. Thus, it can be widely applied in clinical research. For example, in a study of the relationship between CCT and age, sex and light cerebrovascular impairment, the technique was sensitive enough to discriminate between healthy subjects and patients suffering from-transient ischemic attack, or regressive stroke, and to show the action of a drug on the cerebral circulation in such patients.

    Five cases of cerebral paragonimiasis presenting with hemianopsia, convulsion, and gait disturbance are discussed. The cases were all in the chronic stage. The intradermal paragonimiasis reaction, complement fixation, and Ouchterlony tests were not useful for diagnosis. Computed tomography demonstrated calcifications in all cases in sites consistent with the foci of symptoms. Surgical treatment in two cases failed to improve symptoms.

  14. Computerized tomographic studies in cerebral palsy

    International Nuclear Information System (INIS)

    Computed tomographic (CT) findings in 200 children with cerebral palsy (CP) were analysed from the viewpoint of clinical manifestations, disease complications and etiological factors. CT scans of 135 cases (67.5%) were found to be abnormal and there were 14 (7%) borderline cases. The major abnormality found on CT scans was cerebral atrophy. Other important changes included focal or diffuse low density area in the brain tissue, congenital malformation, and cerebellar atrophy. From the clinical point of view, a large number of patients with spastic tetraplegia and spastic diplegia showed highly abnormal CT scans. On the other hand, in patients with spastic monoplegia, spastic paraplegia, and athetotic type, CT findings were normal or revealed only minor cerebral atrophy. Most children showing asymmetric clinical symptoms had corresponding asymmetric CT abnormalities which included ventricular enlargement, low density area in the brain tissue, and hemispherical volume. There was a significant correlation between the severity of physical impairment and the extent of CT abnormalities. Severely affected children had grossly abnormal CT scans such as hydranencephaly, polycystic change, and extensive cerebral atrophy. In the patients complicated with epilepsy, the incidence and severity of abnormal CT were higher than those of non-epileptic patients. Mentally retarded patients had variable enlargement of the subarachnoidal space depending on the severity of their mental retardation. Patients with suspected postnatal etiology also had high incidence of severe CT abnormality. CT scan is a valuable tool for evaluating patients with CP and in some cases, possible etiology of the disease may be discovered. (author)
