    Full Text Available Los antimoniales pentavalentes son la primera elección para el tratamiento de la leishmaniasis en Colombia pero la dosis ha tenido que incrementarse en mas de 600% para mantener su eficacia que en distintos reportes varía entre 93 y 25%, lo cual puede reflejar diferencias en la sensibilidad de los parásitos pero más probablemente incumplimiento de los esquemas recomendados. Los resultados de su empleo, así como la situación actual de pentamidina, anfotericina B y miltefosina son revisados y se hace una proyección sobre el desarrollo de la terapia en los próximos años. Para definir el real estado de la respuesta a los medicamentos anti-leishmaniásicos y prolongarles su vida útil, es indispensable establecer mecanismos de vigilancia de los factores implicados en el manejo de la enfermedad por lo que se plantea una estrategia de sitios centinela que permitan observaciones puntuales en el tiempo, en áreas específicas y sobre situaciones particulares.

Es una población que presenta analfabetismo, un alto porcentaje no se encuentra afiliado al sistema de salud y en el mercado laboral las oportunidades para esta población son escasas. Con respecto al transporte y accesibilidad, entendida esta última como señalización, movilidad y comunicación, aún se encuentran barreras arquitectónicas. Se requiere que el país avance en el cumplimiento de los derechos de las personas con discapacidad, para evitar toda clase de discriminación y marginación garantizando una mejor calidad de vida para todos y se dé un empoderamiento mayor a las personas con discapacidad y la comunidad en general.

    SUMARIO

    a La úlcera péptica en la actualidad ha sufrido un cambio positivo en su tratamiento médico y prevención desde el año 77, año de la introducción de la cimetidina y posteriormente con el hallazgo de otras drogas similares aún más potentes como la ranitidina, la oxmetidina y la droga antimuscarínica pirenzepina.
    En el futuro se vislumbra poder utilizar drogas anti-enzimáticas de acción sobre la célula
    parietal para bloquear sistemas enzimáticos necesarios para la producción del HCL (tipo omeprazoles, timotrazoles y fenoctimina.
    b Gracias a esas drogas la dieta es amplia, fácil de cumplir sin alterar los actos sociales y de trabajo del paciente. Todo esto obra indirectamente como un SISTEMA ANTI-STRESS ya que el paciente, sintiéndose mejor, pudiendo dormir por no tener dolor, llevando una vida normal tanto social como de trabajo, vive más tranquilo y más confiado. Todo esto le
    confiere un estado de seguridad, de tranquilidad y bienestar tanto mental como fisico.

    Los anti-ácidos se usan en plan opcional y ocupan un segundo lugar muy distante en la terapéutica antiulcerosa.
    Los antiguos anticolinérgicos prácticamente están entrando en la historia pasada de la farmacología como drogas antiulcerosas.
    c Un estudio multicéntrico colombiano con pirenzapina en 59 pacientes con enfermedad ulcerosa produce eficacia terapéutica en eI91.5% que es una cifra similar a la obtenida en otros países de Europa,

    Canadá y Estados Unidos, cifras que allí van desde el 68 hasta el 95% de éxito; los efectos colaterales son mínimos (algunos casos de sequedad bucal sin afectar las esferas sexual, hepática o cerebral.
    d La citoprotección que se logra con las drogas específicas es en la actualidad un gran avance terapéutico cuando hay necesidad de utilizar aspirinas, aspirinoides y/o esteroides en pacientes ulcerosos o con historia de enfermedad digestiva alta y

También se hace una revisión bibliográfica del turismo de salud desde una perspectiva histórica y contemporánea con la intención de conocer sus orígenes, evolución, cambios y tendencia actual. Se encontró, primero, que el turismo de salud no es un fenómeno nuevo, debido a que hay mucha evidencia acerca del mismo en el mundo antiguo. Segundo, que el movimiento internacional de pacientes ya no se da desde los países en desarrollo hacia los países desarrollados, sino en sentido contrario. Lo anterior se explica por los altos costos de los servicios de la salud, la elevada proporción de adultos mayores y los problemas asociados con la cobertura del seguro medico en los países desarrollados, entre otras causas. En general, se espera que los flujos de turistas de salud sigan aumentando en favor de los países en desarrollo.Palabras clave: turismo; salud; bienestar; desarrollo; servicios.Health tourism: Concept, history, development and current state of global marketAbstractIn this working paper is developed the conceptual framework of the tourism of health and its two main strands of study: from the medicine and tourism.

    Full Text Available No hay duda de que poder disponer de órganos animales para trasplante solucionaría el problema de su escasez. Pero para que los xenotrasplantes puedan llegar a ser una realidad clínica, se debe superar de forma tres barreras: la inmunológica, la fisiológica y el riesgo de xenozoonosis. Desde el punto de vista inmunológico, la condición necesaria sería que el xenorrechazo pudiera modularse y transformarse a un allorejection-type. Los avances en la tecnología transgénica han resuelto por completo el rechazo hiperagudo, y se han obtenido sobrevidas máximas de meses para el riñón y el corazón, estas sobrevidas han permitido estudiar la compatibilidad fisiológica de estos órganos porcinos trasplantados en los monos durante estos períodos. En cuanto a las barreras infecciosas, con el desarrollo biotecnológico actual en el área de la producción porcina, se asegura el nacimiento de lechones completamente libres de patógenos específicos. Hasta la fecha no se ha comunicado ningún xenotrasplante clínico con órganos porcinos transgénicos. La razón de ello es que existe unanimidad en que todavía las barreras inmunológicas no se han superado. En la actualidad todos los esfuerzos están orientados a estudiar los mecanismos del rechazo vascular agudo retardado para así poder diseñar estrategias que lo prevengan con efectividadThere is no doubt that having animal organs for transplantation will solve the problem of their scarcity, but for xenotransplantations to turn into a clinical reality, it is necessary to overcome three barriers: the immunological, the physiological and the xenozoonosis risk. From the immunological point of view, it would be necessary that the xenorejection could be modulated and transformed into an allorejection type. The advances of transgenic technology have completely solved the hyperacute rejection, and maximum survivals of 3 months have been attained for the kidney and the lung. These suvivals have

    Full Text Available El estudio de los procesos de planificación en otras latitudes permite tener una referencia de la relación indisoluble que existe entre las diferentes escalas territoriales, así como las tendencias que actualmente se desarrollan en torno a las políticas urbanas. La visión estratégica del desarrollo territorial resulta esencial para promover la competitividad de las ciudades y garantizar una calidad de vida óptima. Para comprender la situación actual del desarrollo urbano en nuestro país, es necesario revisar los antecedentes históricos de los modelos económicos impulsados a inicios de los años 80’s, así como el marco legal promulgado en esa misma década. Las condiciones rurales del territorio en ese momento permitieron que la mancha urbana fuera expandiéndose de forma horizontal sin mayores preocupaciones por la presión que más tarde ese modelo generaría sobre las áreas agrícolas y las zonas de protección forestal, así como en los sectores donde el recurso hídrico presenta la mayor vulnerabilidad. El desarrollo extensivo de las ciudades con bajas densidades de población, con carencias importantes de servicios e infraestructura de soporte suficiente, con un stock reducido de espacios públicos y con problemas de movilidad, consume una gran cantidad de recursos ambientales y económicos, lo que lo hace insostenible. Por otra parte, la gentrificación social y la fragmentación espacial, resultan consecuencias nefastas del modelo de ocupación promovido mayoritariamente por el sector privado. La falta de políticas públicas, planes, programas y acciones concretas para una adecuada gestión urbana, ha producido que la Gran Área Metropolitana (GAM sea una de los territorios más rezagados de América Latina en términos de planificación de su territorio, lo que se refleja no sólo en la ausencia total de discusión sobre estos temas, sino en la omisión de principios legales básicos para promover una adecuada gesti

    Full Text Available En algunos medios de comunicación se ha informado sobre supuestos riesgos para la salud, especialmente en el ámbito escolar, derivados de la exposición a las radiofrecuencias (RF emitidas por los sistemas de telecomunicación inalámbricos (wifi, en su abreviatura en inglés. Estas noticias han generado demandas de información que las autoridades sanitarias competentes en salud ambiental deben responder de forma transparente, clara, eficaz y basada en el conocimiento científico actual. En este trabajo se describen las principales características técnicas de estos sistemas, las normas que regulan su funcionamiento, los niveles de emisión autorizados y los niveles observados en algunos estudios específicos.Hasta el momento se han realizado muy pocos trabajos específicos de los efectos sobre la salud derivados de la exposición a las RF que emiten estos sistemas. En este trabajo se describen las principales evaluaciones de riesgo y los estudios más relevantes publicados por agencias internacionales especializadas de reconocido prestigio. Se detalla el estado actual del conocimiento sobre los efectos de las RF sobre la salud y las recomendaciones internacionales formuladas sobre la seguridad de estas tecnologías.Se concluye que no hay evidencia consistente hasta la fecha de que la exposición a señales de radiofrecuencia procedentes de wifi, por debajo de los niveles aceptados internacionalmente, tengan efectos adversos para la salud de la población general. No hay razones que justifiquen que los sistemas wifi deban ser retirados de las escuelas o que no deban ser utilizados por otros grupos de la población.

Su aplicación y entrenamiento sistemático se remonta a la parte final de la década de los sesenta, cuando Sergio Yulis introducela terapia conductual en los cursos de psicoterapia. Durante los primeros años se realizanvariadas aplicaciones tanto en área básica como aplicada. Durante el año 1973 muchosdocentes deben abandonar el país, produciéndose un retroceso en el avance de la disciplina.Actualmente la orientación es considerada como una de las escuelas fundamentales en laformación de los futuros psicólogos y otros profesionales de la salud aun cuando no se cuentecon la mayor preferencia entre la comunidad psicológica chilena. No existe ni en la formaciónni en el país en la actualidad la fuerte presencia del conductismo que existió a finales de lossetenta.

    Full Text Available El carcinoma hepatocelular (CHC es la neoplasia primaria hepática más frecuente. Constituye el sexto tumor más habitual en el mundo, con más de 500.000 casos diagnosticados cada año y es la tercera causa más común de muerte por cáncer.Esta enfermedad afecta de manera casi exclusiva a pacientes con hepato-patía crónica que han desarrollado cirrosis, especialmente la relacionada con los virus de la hepatitis B y C, siendo en este grupo de sujetos el CHC la causa más frecuente de muerte.La incidencia del hepatocarcinoma varía ampliamente a lo largo de la geografía mundial. Se han descrito tasas de 2 a 50 casos por 100.000 habitantes al año, en correlación a la epidemiología de sus factores de riesgo y la distribución de los diversos genotipos virales. Las zonas más prevalentes son el Sudeste Asiático y el África Subsahariana, donde la infección por el virus de la hepatitis B (VHB es endémica. Los estudios más recientes objetivan un aumento mundial en la incidencia del CHC, incluyendo los países occidentales, debido a la mayor diseminación del virus de la hepatitis C (VHC en las décadas de los 60 y 70 además de un aumento en el consumo excesivo de alcohol.La elevada complejidad de esta neoplasia y las patologías con las que se haya íntimamente relacionada, hacen necesario un abordaje multidiscipli-nar para su manejo, implicando a múltiples especialidades tanto médicas como quirúrgicas.

    Full Text Available Se aborda la importancia de las exportaciones de ganado bovino en pie a los Estados Unidos de América, destacando el valor comercial que representa para México la entrada de divisas por 700 millones USD anuales por este concepto. La comercialización de ganado se ve frenada por barreras no arancelarias, tales como la tuberculosis (TB, brucelosis y las garrapatas. Se ha formado un grupo binacional de expertos para tratar estos temas. En el tema de garrapatas se han establecido sistemas de colaboración entre ambos países para la identificación de especies de garrapatas y la rastreabilidad de los casos que sean cuarentenados, desde la línea fronteriza hasta su origen en los diferentes estados mexicanos. Se generó un Proyecto de la Franja Fronteriza para la erradicación de la garrapata Boophilus en los estados mexicanos limítrofes con el estado de Texas, consistente en la identificación de predios infestados, tratamientos ixodicidas e inspección del ganado para exportación a los Estados Unidos. Se discuten las acciones que ambos países están llevando a cabo para la erradicación de garrapata Boophilus en la frontera y para evitar la llegada de ganado con garrapatas a las estaciones cuarentenarias de exportación. Se concluye sobre la necesidad de reforzar y mejorar estos programas.

    Full Text Available Aún cuando en los Estados Unidos existe gran demanda de servicios de salud mental infantil, tradicionalmente muchos niños no han sido atendidos adecuadamente. Esto, en parte, se debe a los obstáculos en el acceso a los servicios y al resultado de un sistema de cuidado fragmentado y desorganizado. Sin embargo, en las últimas dos décadas se ha alcanzado un progreso sustancial en la manera de encarar estos problemas. Este artículo revisa la demanda de servicios de salud mental infantil que existe en los Estados Unidos y describe intentos recientes para mejorar la coordinación y el acceso al sistema de servicio de salud mental infantil. Se discuten la introducción de sistemas de cuidado, la expansión de servicios basados en la escuela y las innovaciones en la provisión de servicios a la comunidad. Children's Mental health: Current trends in the need for and provision of services in the United States traditionally many children have gone unserved. This has been partly due to barriers in accessing services and the result of a fragmented and disorganized system of care. However, in the last two decades substantial progress has been made in adressing these problems. This article reviews the need for children's mental health services in the United States, and describes recent attempts to improve coordination and access to the children's mental health service system. The introduction of systems of care, the expansion of school-based services, and innovations in the provision of community services are discussed.

  7. Aportaciones del Alumnado al estado actual de la calidad de la docencia en Anatomía

    Directory of Open Access Journals (Sweden)

    J. A. Prada

    Full Text Available Con el presente trabajo nos hemos planteado el desarrollo de un sistema de recogida de información acerca de las expectativas y valencias en la docencia universitaria en los alumnos. Para ello hemos diseñado una encuesta específica donde se analizan los aspectos concretos que intervienen en el aprendizaje de la Anatomía, así como el valor subjetivo que el Alumno aporta a los mismos. De los resultados obtenidos hemos extraído el concepto de "Calidad referida" que es aquella que perciben los Alumnos. Los factores que los Alumnos piensan que dan Calidad a la enseñanza, como receptores finales del sistema, difieren de los aspectos contextuales que las actuales encuestas estudian. Consideramos que las opiniones del Alumnado no quedan suficientemente expuestas en la redacción actual de las encuestas, a pesar de que suponen un poderoso elemento de retroalimentación en la mejora de la calidad. Sobre la base de nuestro criterio de "Calidad referida" los Alumnos definen más claramente los aspectos relevantes que afectan al aprendizaje. Para ello pensamos que las encuestas deben ser específicas bajo las peculiaridades de cada área de conocimiento. Los resultados de dichas encuestas probablemente serían más útiles para los Docentes, a los que aportaría un conocimiento cierto de las expectativas del Alumnado.

Para lograr dichos objetivos realizaremos una breve contextualización histórica de la relación Estado-Pueblo mapuche; se analizará el modelo económico, principalmente en lo concerniente a la inversión forestal y la ejecución de megaproyectos en territorio mapuche; la Ley indígena en general y el concepto de pueblo indígena en particular; el denominado conflicto mapuche y la Ley anti-terrorista. Todo ellos, esperamos, servirán de elementos de juicio y antecedentes importantes para aproximarnos al problema de la relación entre la democracia formal y los derechos indígenas._______________________ABSTRACT:It is not possible to understand the relation between the Mapuche Nation, the Chilean State and the democracy, without understanding the type of historical bond that has occurred between the State and the Mapuche nation from the onset of Chile as a Country.

    Full Text Available Es muy frecuente en el ambiente médico y entre los padres de familia el uso y abuso de antipiréticos buscando disminuir abruptamente la temperatura, mejorar los síntomas derivados de la fiebre y contrarrestar las reacciones adversas de la misma. Por otro lado, existen diferentes conceptos acerca de la elección del antipirético más eficaz y seguro en niños y su ruta de administración, así como su utilidad en la prevención de convulsiones febriles, entre otras. Este artículo pretende dar claridad a las controversias en el manejo de la fiebre mediante la revisión de la literatura, incluyendo solo ensayos clínicos, meta análisis, guías de manejo y revisiones de tema, publicadas en las dos últimas décadas. Para tal fin se revisaron las bases de datos Cochrane, PubMed y Medscape.Antipyretics are very often used between physicians and parents to treat fever and relief its symptoms and prevent vaccination side effects. Indeed, there is a misconception about the prevention of recurrence of febrile seizures with antipyretics and this leads to overdoses, side effects and, therefore, more parent´s anxiety. There are contradictory concepts about the election of safer and better antipyretic in children and its better administration via: oral and rectal paracetamol, ibuprofen, ketoprofeno, nimesulide, oral and intramuscular metamizol, paracetamol plus ibuprofen and ponging/lukewarm bath. All these alternatives have been studied by many researchers without consensus because more trials with bigger samples and longer time of study are needed. No clarity exists between doctors and parents about the antipyretic's effects over febrile seizure prevention and prophylaxis of post vaccine symptoms. This article pretends to find actual evidence about fever , its implications and use of antipyretics in children through searching on data bases like PubMed, Cochcrane, and Medscape.

    Full Text Available Actualmente la formación de Psicólogos/as enfrenta retos serios en muchos de los países del Caribe y América Latina. Entre estos me interesa destacar: el debate sobre educación pública vs. educación privada, el aparente excedente de profesionales de la Psicología en algunos de nuestros países y la contracción y/o privatización de programas gubernamentales que tiene como consecuencia, el desplazamiento de Psicólogos/as al sector privado o a actividades profesionales desvinculadas de la Psicología. Debo aclarar, estos no son meros “debates”, se trata más bien de la aprobación e implantación de políticas, que ya inciden sobre el acceso de determinados sectores a la educación de post-grado en Psicología y sobre las posibilidades de inserción en el mundo laboral de egresados de programas de post-grado, así como de programas de licenciatura. Veamos brevemente cuál es el estado actual, no sin antes sugerir revisar la edición especial de la Revista Interamericana de Psicología publicada en el año 2000 y editada por la Dra. Ana Isabel Álvarez en la que se discute y analiza la historia de la Psicología en el Caribe. Esa edición representa un trabajo valiosísimo para nuestra disciplina y es fundamental para entender el presente de la misma. Además debo advertir que en este trabajo sólo presentaré la situación en cuatro países: Puerto Rico, Cuba, República Dominicana y Haití, ya que son los países en los que sostengo vínculos profesionales, por lo que conozco por experiencia directa lo que en ellos ocurre en términos de la disciplina.

    Full Text Available Con la adopción del resultado global (comprehensive income a partir de la década de los noventa del siglo XX por los organismos emisores de normas contables más relevantes en el concierto mundial, entre los que cabe destacar el International Accounting Standards Board (iasb y el Financial Accounting Standards Board (fasb, estamos asistiendo a un posicionamiento a favor del enfoque del excedente limpio. Como consecuencia el resultado empresarial queda más vinculado a las oscilaciones de los precios de los títulos y a los tipos de cambio, frente al enfoque del excedente sucio que nos lleva a la determinación del mismo desde una óptica más restrictiva y, por ello, mucho menos conectado con la realidad de los mercados. En este trabajo nos planteamos como primer objetivo el estudio desde una óptica histórica y conceptual del antiguo y controvertido debate del enfoque del excedente limpio versus el enfoque del excedente sucio, circunscrito esencialmente a los países del área de influencia anglosajona. Posteriormente, queremos constatar que con la revisión de la Norma Internacional de Contabilidad 1 (nic 1 del International Accounting Standards Board (iasb en el año 2007 cobra más fuerza el resultado global; con ello se confirman los planteamientos a favor del enfoque del excedente limpio, lo que origina la desaparición del estado de resultados tradicional del conjunto completo de estados financieros si las empresas, según dicha norma, optan por revelarlo en el estado de resultados globales; todo ello con el propósito de reportar más utilidad a los inversionistas, quienes son considerados usuarios primordiales en los modelos contables anglosajones a los que tendemos.

    Full Text Available Resumen: La cirugía urológica tiene una antigüedad insospechada. El abordaje laparoscópico ha estado en el armamentario de la especialidad desde sus inicios. Sin embargo, recién en las últimas décadas y gracias al gran desarrollo tecnológico en imágenes e instrumental, es que se ha logrado introducir casi rutinariamente en la práctica urológica. Los beneficios de la cirugía laparoscópica son incuestionables y la evidencia nos muestra que cada vez será mayor la tendencia a realizar cirugías por esta vía. El advenimiento de la cirugía laparoscópica asistida por robot ha permitido en los últimos años implementar este abordaje para cirugías más complejas, que parecían imposibles de realizar de otra forma que no fuera por vía abierta. El propósito de esta revisión es describir con una perspectiva histórica el desarrollo de la cirugía mínimamente invasiva en urología y sus principales aplicaciones hoy en día. Summary: Urological surgery has an unsuspected age. The laparoscopic approach has been in the specialty's armamentarium since its beginnings. But only in recent decades and thanks to the great technological development in images and instruments, is that it has been almost routinely introduced into urological practice. The benefits of laparoscopy are unquestionable and the evidence shows that the tendency to perform surgeries in this way will be greater every time. The advent of robot assisted laparoscopic surgery in recent years has allowed surgeons to implement this approach for more complex surgeries, which seemed impossible to perform otherwise than by open surgery. The purpose of this review is to describe with a historical perspective the development of minimally invasive surgery in urology and its main applications today.

    Full Text Available La relación entre emociones y vida moral constituye hoy en día un amplio campo de investigación en filosofía y psicología. Al respecto, Martha Nussbaum ofrece importantes puntos de reflexión que nos llevan a preguntarnos por aquellas facultades cognitivas que estructuran las emociones morales, como la compasión, y diferencian radicalmente la expresión emocional humana de la de animales no humanos. La inclusión de creencias y actos valorativos como elementos constitutivos de las emociones morales hacen que la propuesta de Nussbaum se oriente hacia una disolución de la vieja dicotomía moderna entre razón y emoción, a la vez que posibilita una mejor comprensión del valor ético de las emociones como informadoras de vulnerabilidad y daño moral. De esta manera, la perspectiva cognitivo-evaluadora de Nussbaum ingresa a la actual discusión sobre cómo las emociones pueden influir en nuestros juicios y decisiones morales en medio de un mundo conflictivo, inequitativo y que genera sufrimiento, pero que, no obstante, tiene aún posibilidades de consolidar sociedades justas, democráticas y plurales.

    Full Text Available La adventicia se ha definido como la capa de tejido conectivo más externa de un vaso y no formaría una unidad con la estructura vascular. El término “adventicia” proviene del latín adventicius, que significa “venido de afuera, extraño”. Estos conceptos tal vez constituyan la causa de la subestimación del papel fisiológico de esta túnica. Al presente es bien conocido que la adventicia contiene vasa vasorum y nervi vasorum con funciones nutricionales y de control, respectivamente. A ello se suma la presencia de factores bioquímicos que serían responsables de cambios en la conducta elástica y viscosa de la pared arterial a través de una regulación de la función muscular lisa.En este trabajo se realiza una síntesis del papel estructural y fisiológico de la adventicia; se analizan además datos clínicos y experimentales que se comparan con resultados originales publicados por el autor.

    El problema del colesterol y su implicación con la ateroesclerosis ha sido preocupación de científicos, trece de ellos merecedores del Premio Nobel. Desde su aislamiento en 1784, investigadores de áreas diversas de la medicina han estudiado esta pequeñísima molécula que tiene a su vez, 30 enzimas involucradas en su metabolismo. La propiedad más interesante es su absoluta insolubilidad en agua que lo hace letal en su efectos. Organismos multicelulares realizan el transporte de la molécula esterificando el esterol en cadenas de ácidos grasos y empaquetando estos ésteres dentro de núcleos hidrofóbicos que son las lipoproteínas del plasma.

    La identificación en 1938 por Carl Müller de la hipertrigliceridemia familiar, permitió demostrar en 1970 la evidencia de dos formas, la heterocigótica y la homocigótica severa. Culminan las investigaciones con los hallazgos de Goldstein y Brown acreedores del Nobel de Medicina 1985, quienes gracias al hallazgo pionero en el cultivo de fibroblastos, establecen el papel enzimático en la biosíntesis del colesterol, secuencian los receptores a nivel molecular y caracterizan el genoma. Así se establece la acción aterogénica de las lipoproteínas de baja densidad.

    En un esfuerzo del grupo médico de la Asociación Colombiana de Diabetes (ACD, de actualizar el concepto y los resultados de los recientes descubrimientos farmacológicos de los inhibidores de la HMG CoA reductasa, he querido que mentes jóvenes que están trabajando como docentes, residentes e internos de nuestra institución, dentro del plan de integración con la Universidad Javeriana traigan a ustedes, señores Académicos un mensaje sumamente conciso, tratando de hacerlo lo más sencillo en su comprensión y práctico en sus aplicaciones.

    Full Text Available Las enfermedades tiroideas pueden ser diagnosticadas, en la mayoría de los casos, por la clínica. Sin embargo, existen situaciones que requieren de las pruebas de función tiroidea con el fin de valorar correctamente al paciente en las etapas iniciales de la disfunción de esta glàndula, con el fin de establecer el tratamiento adecuado de forma individual y el seguimiento de la evolución de la enfermedad. En esta revisión hacemos referencia a las pruebas empleadas para valorar el estado de la función tiroidea y se señalan sus ventajas, limitaciones y tendencias actuales. La determinación de TSH por procederes de segunda y tercera generaciones permite establecer el diagnóstico del hipertiroidismo e hipotiroidismo primarios, aún en las formas subclínicas de ambos, al mostrar inhibición o hipersecreción, respectivamente, así como la dosis adecuada de l-levotiroxina y orientar a una causa hipofisaria de esta disfunción. La determinación de T4 es de gran valor para conocer la intensidad de la disfunción tiroidea y para valorar la eficacia del tratamiento en las primeras semanas de iniciado. La determinación de T3 tiene su principal indicación ante la sospecha de la presencia del llamado hipertiroidismo por T3. La determinación de T4 y T3 totales da lugar a una interpretación incorrecta en cuanto a las situaciones que modifican la globulina transportadora de tiroxina (TBG. La tendencia actual es al empleo de TSHs como prueba inicial para el diagnóstico de la disfunción tiroidea, la cual se debe indicar teniendo siempre en cuenta la clínica y, de ser necesario, asociarla a la determinación de T4 o T3 libres.The thyroid diseases may be diagnosed in most of cases by the clinics.

    Giordany, B.R.

    1985-01-01

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

The case also explains how the clinical presentation can be misleading unless a high index of suspicion is maintained to reach the ultimate diagnosis. (author)

Para ello hemos diseñado una encuesta específica donde se analizan los aspectos concretos que intervienen en el aprendizaje de la Anatomía, así como el valor subjetivo que el Alumno aporta a los mismos. De los resultados obtenidos hemos extraído el concepto de "Calidad referida" que es aquella que perciben los Alumnos. Los factores que los Alumnos piensan que dan Calidad a la enseñanza, como receptores finales del sistema, difieren de los aspectos contextuales que las actuales encuestas estudian. Consideramos que las opiniones del Alumnado no quedan suficientemente expuestas en la redacción actual de las encuestas, a pesar de que suponen un poderoso elemento de retroalimentación en la mejora de la calidad. Sobre la base de nuestro criterio de "Calidad referida" los Alumnos definen más claramente los aspectos relevantes que afectan al aprendizaje. Para ello pensamos que las encuestas deben ser específicas bajo las peculiaridades de cada área de conocimiento. Los resultados de dichas encuestas probablemente serían más útiles para los Docentes, a los que aportaría un conocimiento cierto de las expectativas del Alumnado.In the present work we confront the development of a capture information system about the Student values and expectations in the universitary teaching.

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

Abdominal emergencies in children mostly present with pain, tenderness, occasionally coupled by vomiting, fever, abdominal distension, and failure to pass meconium or stools. Diarrhea, blood per rectum, abnormal laboratory tests and lethargy may also be manifestations of acute abdominal conditions. Abdominal emergencies have a different aetiology, depending on age and whether the pain is acute or chronic. Symptoms have to be matched with age and gender. Newborns up to 1 months of age may have congenital diseases: atresia, low obstruction including Hirschsprung's disease, meconium ileus. Meconium plug is one of the commonest cause of low obstruction in newborns that may also develop necrotizing enterocolitis, incarcerated inguinal hernia and mid-gut volvulus. Past the immediate postnatal period, any duodenal obstruction should be considered midgut volvulus until proven otherwise and patients should undergo ultrasonography and/or properly performed upper GI contrast study that records the exact position of the deduno-jejunal junction. Infants 6 months-2 years carry the risk of intussusception, mid-gut volvulus, perforation, acute pyelonephritis. Preschool and school-aged children 2-12 years carry the risk of appendicitis, genito-urinary abnormalities including torsion, urachal abnormalities, haemolytic uremic syndrome and Henoch-Schonlein purpura. Children above 12 years suffer from the same conditions as in adults. Most conditions may affect any age despite age predilection. Abdominal solid organ ultrasonography (US) coupled with gastrointestinal ultrasonography is the principle imaging modality in radiosensitive

    Abdominal angina due to occlusive disease of the mesenteric arteries has been the to become clinically manifest only in the presence of severe disease in at least two of the following vessels: celiac, SMA, and IMA. Still, many patients who gradually develop significant two-vessel disease have few or no associated symptoms. Differences in collateral circulation and in cardiac index account for some of the clinical variation. The usual clinical manifestations include severe post-prandial pain, sitophobia (fear of eating because of the anticipated symptoms), and profound weight loss. Uncommonly, diarrhea, nausea, or vomiting may be encountered. Smoking is a common historical feature. Most series document a female predilection. Aside from occasional abdominal bruits and (more commonly) findings of peripheral vascular occlusive disease, the physical exam discloses only cachexia. But the differential diagnosis of profound weight loss is extensive. Therefore, abdominal angina has always created a diagnostic challenge. Multiple imaging modalities are often employed, and a seemingly negative evaluation often culminates in biplane aortography. The latter typically reveals stenoses and/or occlusions in at least two of the three mesenteric arteries. The authors discuss how a variety of surgical treatments, including thromboendarterectomy and bypass grafting, have evolved. Recently reported results have been excellent

La promoción y desarrollo del sector frutícola representa para Colombia una importante fuente de crecimiento de la agricultura, de generación de empleo rural y de desarrollo con equidad para las distintas regiones puesto que las frutas pueden asentarse en los diversos pisos térmicos de que dispone el país, a la vez que conforma una producción administrada con criterios de eficiencia y sostenibilidad en escalas que van desde micro, pequeños y medianos productores hasta grandes productores y empresas. Durante las últimas cuatro décadas el área sembrada en frutas expresa una dinámica de constante crecimiento, consiguiendo así aumentar su participación tanto en el área dedicada a cultivos no transables, como en el total del área de la agricultura sin café. Así, mientras en 1970 la participación del área frutícola en los no transables era del 1,6%, en el 2005 ésta era del 12,6%. Las áreas plantadas en frutas en Colombia pasaron de 191.035 ha en 2003 a 225.325 ha en 2007 lo que representa un crecimiento de 17,9 %, mientras que los volúmenes de producción pasaron de 2.675.736 t a 3.279.264 t en el mismo período en 47 especies frutícolas. El Plan Frutícola Nacional - PFN, constituye una propuesta estratégica conformada por conjunto coherente de objetivos, estrategias y programas que, con base en una visión de futuro, buscan la meta inicial de duplicar el área de la producción frutícola nacional, asegurar las condiciones tecnológicas y de innovación para una producción sostenible y de calidad, agregar valor en la cadena frutícola, y lograr una vinculación plena en los mercados internacionales. Se busca que los participantes conozcan los principales desarrollos de la fruticultura Colombiana, sus retos y oportunidades para la próxima década.

    Full Text Available Introducción: por lo común, la adicción a las drogas se trata con psicoterapia y farmacología que evita la unión de las sustancias psicoactivas a receptores específicos en el cerebro. El resultado de estos tratamientos no ha sido del todo satisfactorio, por lo que el desarrollo de terapias más eficaces representa un reto constante para tratar las adicciones. Una alternativa a la farmacología antiadictiva es la vacunación activa dirigida contra las sustancias de abuso. Objetivo: esta revisión reúne la información disponible sobre los fundamentos y avances científicos en la generación de una terapia inmunológica, que coadyuve al tratamiento de la adicción a sustancias como la heroína-morfina, la cocaína, la nicotina y la anfetamina. Método: se consideraron los reportes científicos disponibles en PubMed –de 2005 a abril de 2017–, sobre los fundamentos, la metodología empleada, los estudios preclínicos y clínicos, y los resultados obtenidos en dichas investigaciones para generar vacunas contra las drogas. Resultados: las vacunas lograron mitigar los efectos producidos por las sustancias en los estudios preclínicos en modelos de estudio en animales; sin embargo, con pacientes humanos los resultados no han sido del todo satisfactorios. Discusión y conclusiones: a pesar de los esfuerzos realizados por diferentes grupos de investigación y compañías farmacéuticas para generar vacunas terapéuticas contra el uso de diferentes drogas, ninguna ha alcanzado la fase III de estudios clínicos. En la actualidad, se continúa con los esfuerzos para lograr que las vacunas contra las adicciones alcancen su máxima eficiencia y eficacia, y contribuyan al tratamiento de la adicción a las drogas.

    Comparisons between the merits of many different motion analysis systems is a very difficult task because their published specifications are obtained in a widely varying conditions and in some cases refer only to the performance of small components of an integrated system. The main purpose of this study is the introduction of the reader to the most important tecnologic characteristics that define the performance of the modern optoelectronic systems on the basis of data acquisition and signal processing. The evolution of these systems during the last two decades brought about a need for determination of objective criteria and standarized procedures that allow potential users evaluate different systems before spend money. In short, the decision for an optoelectronic system should be made on the basis of the investigations´ particular purposes, systems’ performance and price.

    Full Text Available Aunque la evolución de la delincuencia y la desviación responde a la dinámica de los acontecimientos sociales, económicos y políticos a nivel global, es posible que la Criminología tenga un impacto positivo en este campo. Para lograr esta meta, será necesario desarrollar los cursos interdisciplinarios en Criminología y justicia penal alrededor del mundo, adoptar programas y políticas basados en la recopilación y evaluación sistemática de evidencias, y convertirnos en criminólogos efectivos, no solamente en el ámbito científico, sino también en el mundo político. Actualmente, la Criminología no es una disciplina madura y no estamos seguros sobre cómo responder al problema de la delincuencia. Carecemos de instrumentos de diagnóstico preciso, de un cuerpo de conocimientos definitivos, de una comprensión de causas y efectos, y de una serie de modalidades de tratamiento generalmente consistentes. En este sentido, los criminólogos se parecen en algo a los médicos del Siglo XVIII. This article suggests that while crime and deviance are subject to the dynamics of global socio-economic-political events, the field of criminology can have a marked, positive impact in this realm. To achieve this end, there is a need to advance interdisciplinary criminology/criminal justice education, to embrace systematic, evidence based program and policy evaluation, and to become effective political as well as scientific criminologists. Criminology is not a mature science at this point, and we are not certain how to systematically respond to the crime problem. We lack accurate diagnostic instruments, a definitive body of knowledge, an understanding of cause and effect, and we do not possess a series of generally consistent treatment modalities. In this context, criminologists are somewhat akin to physicians of the 18th century.

    ABSTRACT

    Measurements made using an image - based motion analysis system are contaminated with noise generated during the recording and digitizing procedures. So the sampled signal can be considered as the sum of a quantity of true information associated to the physical phenomenon that is taking place and a quantity of information, that is nothing to do with this, representing the systematic and random noise induced by lens distortion, erroneous marker placement, calibration errors, skin and marker movements, digitizing errors, digitizer resolution, etc. Due to the nature of numerical differentiation, unless the random noise is reduced it may be amplified to such an order that the estimated derivative values may contain more error than signal. The main purpose of this study is the introduction of the reader to the most important techniques to treat de position -time data in order to reduce the noise and differentiate the displacement data. Besides, objective criteria are defined to select the most efficient fit data technique in Biomechanics.

    Full Text Available http://dx.doi.org/10.5007/1808-1711.2016v20n1p61 In what follows, I present only part of a program that consists in developing a version of actualism as an adequate framework for the metaphysics of intentionality. I will try to accommodate in that framework suggestions found in Kripke’s works and some positions developed by Amie Thomasson. What should we change if we accept “fictional entities” in the domain of the actual world? Actualism is the thesis that everything that exists belongs to the domain of the actual world and that there are no possibilia. I shall defend that there are abstract artefacts, like fictional characters, and institutions. My argument could be seen as a version of Moore’s paradox: it is paradoxical to say: “I made (created it, but I do not believe it exists”. Moreover, there are true sentences about them. I will examine what it means to include abstract artefacts in the domain of the actual world. I favour a use of “exist” that includes beings with no concrete occupation of tri-dimensional space; to exist, it is enough to have been introduced at some moment in history. Abstract artefacts, like fictional characters, exist in that sense. I argue that it is important to distinguish two perspectives (internal and external in order to clarify the kind of knowledge we have of fictional characters. However, their existence presupposes a relation of dependence to a material basis and the mental activities of many people.

    Abdominal pain is one of the common symptoms reported by children in urgent care clinics. While most children tend to have self-limiting conditions, the treating pediatrician should watch out for underlying serious causes like intestinal obstruction and perforation peritonitis, which require immediate referral to an emergency department (ED). Abdominal pain may be secondary to surgical or non-surgical causes, and will differ as per the age of the child. The common etiologies for abdominal pain presenting to an urgent care clinic are acute gastro-enteritis, constipation and functional abdominal pain; however, a variety of extra-abdominal conditions may also present as abdominal pain. Meticulous history taking and physical examination are the best tools for diagnosis, while investigations have a limited role in treating benign etiologies.

    Adaptation of working environment (social, organizational, physical and physical) should assure higher level of workers' availability and consequently higher level of workers' performance. A special theoretical model for description of connections between environmental factors, human availability and performance was developed and validated. The central part of the model is evaluations of human actual availability in the real working situation or fitness for duties self-estimation. The model was tested in different working environments. On the numerous (2000) workers, standardized values and critical limits for an availability questionnaire were defined. Standardized method was used in identification of the most important impact of environmental factors. Identified problems were eliminated by investments in the organization in modification of selection and training procedures in humanization of working .environment. For workers with behavioural and health problems individual consultancy was offered. The described method is a tool for identification of impacts. In combination with behavioural analyses and mathematical analyses of connections, it offers possibilities to keep adequate level of human availability and fitness for duty in each real working situation. The model should be a tool for achieving adequate level of nuclear safety by keeping the adequate level of workers' availability and fitness for duty. For each individual worker possibility for estimation of level of actual fitness for duty is possible. Effects of prolonged work and additional tasks should be evaluated. Evaluations of health status effects and ageing are possible on the individual level. (author)

In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.

  13. Bladder distension as a cause of abdominal compartment syndrome

    Abdominal compartment syndrome (ACS) is increasingly identified in critically ill patient and its harmful effects are well documented. The disparity among the pressure, volume in abdominal cavity and its contents, results in ACS. The actual incidence of ACS is not known. However, it has been observed predominantly in patients with severe blunt and penetrating abdominal trauma, ruptured abdominal aortic aneurysms, retro- and intra-peritoneal hemorrhage, pneumoperitoneum, neoplasm, pancreatitis, ascites and multiple bone fracture. We present a case of 40-year female who underwent emergency cesarean section and developed abdominal compartment syndrome due to urinary bladder distension secondary to blockade of urinary catheter with blood clots. This is a very unusual cause of ACS. (author)

    1987-01-01

    The imaging search for a suspected abdominal abscess is common in hospitalized patients, especially after recent abdominal surgery. This paper examines the role of CT in the detection, localization, and treatment of abdominal abscess. The accuracy, limitations, and technical aspects of CT in this clinical setting are discussed. The diagnosis of an abscess is based on the demonstration of a circumscribed abnormal fluid collection. Although percutaneous aspiration with gram stain and culture is usually indicated to differentiate abscess from other fluid collections, the CT-based detection of extraluminal gas bubbles makes the diagnosis of an abscess highly likely. CT is compared with conventional radiographic studies, US, and radio-nuclide imaging. Specific CT and clinical features of abscesses in the following sites are emphasized: subphrenic space, liver, pancreas, kidneys, psoas muscle, appendix, and colonic diverticula. Most abdominal abscesses can be successfully treated with percutaneous drainage techniques. The techniques, results, and limitations of percutaneous abscess drainage are reviewed

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition. Copyright © 2016 SERAM.

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

    Abdominal paracentesis and thoracocentesis are common bedside procedures with diagnostic, therapeutic and palliative roles. We describe a useful and familiar a useful and familiar technique with the use of a multiple lumen catheter commonly used for central venous line insertion for drainage of ascites or moderate to large pleural effusions. The use of a multiple lumen catheter allows easier and more rapid aspiration of fluid with a smaller probability of the side holes being blocked as compared to the standard needle or single catheter methods. This is particularly useful in situations where the dedicated commercial kits for thoracocentesis and abdominal paracentesis are not readily available.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

    Science.gov (United States)

    Grover, Madhusudan; Drossman, Douglas A

    2010-10-01

    Functional abdominal pain syndrome (FAPS) is a relatively less common functional gastrointestinal (GI) disorder defined by the presence of constant or frequently recurring abdominal pain that is not associated with eating, change in bowel habits, or menstrual periods (Drossman Gastroenterology 130:1377-1390, 2006), which points to a more centrally targeted (spinal and supraspinal) basis for the symptoms. However, FAPS is frequently confused with irritable bowel syndrome and other functional GI disorders in which abdominal pain is associated with eating and bowel movements. FAPS also differs from chronic abdominal pain associated with entities such as chronic pancreatitis or chronic inflammatory bowel disease, in which the pain is associated with peripherally acting factors (eg, gut inflammation or injury). Given the central contribution to the pain experience, concomitant psychosocial disturbances are common and strongly influence the clinical expression of FAPS, which also by definition is associated with loss of daily functioning. These factors make it critical to use a biopsychosocial construct to understand and manage FAPS, because gut-directed treatments are usually not successful in managing this condition.

  11. Adult abdominal hernias.

    LENUS (Irish Health Repository)

    Murphy, Kevin P

    2014-06-01

    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

Between August 1998 and April 1999, 536 consecutive patients with non-traumatic abdominal pain were entered into our study. Using a computer order entry system, physicians were asked to identify: (a) their most likely diagnosis; (b) their level of certainty in their diagnosis; (c) if they thought CT would be normal or abnormal; (d) their treatment plan (prior to knowledge of the CT results); and (e) their role in deciding to order CT. This information was correlated with each patient's post-CT diagnosis and subsequent management. Pre- and post-CT diagnoses were concordant in 200 of 536 (37%) patients. The physicians' certainty in the accuracy of their pre-CT diagnosis was less than high in 88% of patients. Prior to CT, the management plan included hospital admission for 402 patients. Following CT, only 312 patients were actually admitted; thus, the net impact of performing CT was to obviate the need for hospital admission in 90 of 536 (17%) of patients with abdominal pain. Prior to CT, 67 of 536 (13%) of all patients would have undergone immediate surgery; however, following CT only 25 (5%) actually required immediate surgery. Among patients with the four most common pre-CT diagnoses (appendicitis, abscess, diverticulitis, and urinary tract stones) CT had the greatest impact on hospital admission and surgical management for patients with suspected appendicitis. For patients with suspected appendicitis, CT reduced the hospital admission rate in 28% (26 of 91) of patients and changed the surgical management in 40% (39 of 91) of patients. Our study demonstrates the advantage of performing abdominal CT in the ED for patients with non-traumatic abdominal pain. (orig.)

    Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

    Full Text Available BACKGROUND In the recent times there has been increased incidence of abdominal trauma cases due to several causes. Quick and prompt intervention is needed to decrease the mortality of the patients. So we conducted a study to assess the cause and the management of abdominal trauma cases in our institution. The aim of this study was to know the incidence of blunt and penetrating injuries and their causes, age and sex incidence, importance of various investigations, mode of treatment offered and post-operative complications. To study the cause of death and evolve better management. MATERIALS AND METHODS The present study comprises of patients admitted to and operated in various surgical units in the Department of Surgery at Government General Hospital, attached to Guntur Medical College Guntur, from August 2014 to October 2016. RESULTS Increase incidence seen in age group 20-29 years (30%. Male predominance 77.5%. Mechanism of injury–road traffic accidents 65%. Isolated organ injury–colon and rectum 40%. Other associated injuries–chest injuries with rib fractures 7.5%. Complications–wound infection 17.5%. Duration of hospital stay 8–14 days. Bowel injury management–closure of perforation 84.6%. Resection anastomosis 15.38%. CONCLUSION Thorough clinical examination, diagnostic paracentesis, plain X-ray erect abdomen and ultrasound proved to be very helpful in the diagnosis of intra-abdominal injuries. Spleen is the commonest organ involved in blunt trauma and colon is the commonly injured organ in penetrating abdominal trauma, many patients have associated extremity and axial skeleton injuries. With advances in diagnosis and intensive care technologies, most patients of solid visceral injuries with hemodynamic stability can be managed conservatively. Surgical site infection is the most common complication following surgery. The mortality is high; reason might be patient reaching the hospital late, high incidence of postoperative septic

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

    Full Text Available Objective. To comparatively analyze the efficiency of methods for extracorporeal detoxification (ED of the body in abdominal sepsis (AS and to choose the optimum detoxifying methods in relation to the level of endotoxicosis.Material and methods. 56 patients (41 males and 15 females; mean age 39.4±12.2 years with surgical abdominal infection of various genesis, complicated by the development of sepsis whose treatment included ED methods, were examined. The level of intoxication and the efficiency of detoxification were evaluated by general clinical and biochemical blood parameters, the leukocytic intoxication index, the levels of low and medium molecular-weight substances in the body’s media. Hemosorption, plasmapheresis, hemodialysis, hemodiafiltration, and hemofiltration were used for detoxification.Results. Surgical abdominal infection is accompanied by endotoxemia that has no clear nosological specificity, but it depends on the pattern of a clinical course of the disease and is most pronounced in the septic syndrome. In AS, 80.4% of the patients are observed to have an irreversible decompensation phase and a terminal degree of endotoxicosis, which require detoxification. The use of different ED methods according to the level of intoxication may reduce the level of endotoxicosis and yield a persistent beneficial effect in 85.2% of cases of its application. Conclusion. Filtration and dialysis techniques (hemodialysis, hemofiltration, and hemodiafiltration are the methods of choice in AS. Hemosorption and plasmapheresis may be recommended for use at the early stages of endotoxicosis development and in preserved renal excretory function.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    Full Text Available INTRODUCCIÓN: Los Desórdenes por Deficiencia de Yodo son un problema serio de salud pública, con cerca de 2 mil millones de personas a riesgo de padecerlos, pudiendo causar bocio neonatal, cretinismo, retardo mental, hipotiroidismo, entre otros. Estos desórdenes son aún prevalentes, y en algunos casos los esfuerzos para su erradicación se han traducido en aumento del riesgo de exceso poblacional de yodo y autoinmunidad tiroidea. En Colombia, se desconoce el estado real de yodo en la población. OBJETIVOS: Determinar la mediana de la yoduría en población escolar, y de los hábitos del consumo de sal, función y parámetros de autoinmunidad tiroidea, y cociente intelectual. MATERIALES Y MÉTODOS: Estudio basado en la comunidad, de corte transversal. Se evaluaron las variables sociodemográficas, la frecuencia de bocio y los niveles de TSH, anti-TPO, anti-Tg, anti-TSHR, yoduria, test de factor G de Cattell, y hábitos del consumo de sal. RESULTADOS: El consumo de sal promedio persona/día fue de 18,13 g. El 37,9% presentó bocio. 36,1% tenían un valor límite en el cociente intelectual. La mediana de yoduria fue de 510,3 μg/L. El 42,75% tuvo anti-TPO positivos, y el 2,87% anti-Tg positivos. El 10% presentó niveles de TSH elevados. CONCLUSIÓN: En escolares de zona urbana, hay un exceso en la mediana de yoduria, pudiendo explicarse por el alto consumo de sal. La alta prevalencia de autoinmunidad tiroidea y bocio, junto al alto nivel de la TSH, puede ser consecuencia del exceso en la ingesta de sal y de otros factores medioambientales/ hereditarios.

    Ultrasound examinations were done to evaluate clinically palpable abdominal masses in 125 children. The examinations were normal in 21 patients. In 15 patients, the clinically palpable masses were actually anterior abdominal wall abscesses or hematomas. Final diagnosis was available in 87 of 89 patients with intraabdominal masses detected on ultrasound. The majority (71%) were retroperitoneal masses where two-thirds were of renal origin. Ultrasound diagnosis was correct in 68 patients (78%). All cases of hydronephrosis were correctly diagnosed based on characteristic ultrasound appearances. Correct diagnoses of all cases of adrenal hematoma, psoas abscess, liver hematoma, liver abscess and one case of liver metastases were achieved with correlation of relevant clinical information.

    Fat necrosis is a common pathological change at abdominal cross-sectional imaging, and it may cause abdominal pain, mimic pathological change of acute abdomen, or be asymptomatic and accompany other pathophysiologic processes. Fat necrosis is actually the result of steatosis by metabolism or mechanical injury. Common processes that are present in fat necrosis include epiploic appendagitis, infarction of the greater omentum, pancreatitis, and fat necrosis related to trauma or ischemia. As a common fat disease, fat necrosis should be known by clinicians and radiologists. Main content of this text is the clinical symptoms and CT findings of belly fat necrosis and related diseases.

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain.

    This article discusses abdominal aortic emergencies. There is a common thread of risk factors and causes of these diseases, including age, male gender, hypertension, dyslipidemia, and connective tissue disorders. The most common presenting symptom of these disorders is pain, usually in the chest, flank, abdomen, or back. Computed tomography scan is the gold standard for diagnosis of pathologic conditions of the aorta in the hemodynamically stable patient. Treatment consists of a combination of blood pressure and heart rate control and, in many cases, emergent surgical intervention. Copyright © 2017 Elsevier Inc. All rights reserved.

    The abdominal wall is often neglected as a cause of chronic abdominal pain. The aim of this study was to identify chronic abdominal wall pain syndromes, such as anterior cutaneous nerve entrapment syndrome (ACNES), in a patient population diagnosed with functional abdominal pain, including irritable bowel syndrome, using a validated 18-item questionnaire as an identification tool. In this cross-sectional analysis, 4 Dutch primary care practices employing physicians who were unaware of the existence of ACNES were selected. A total of 535 patients ≥18 years old who were registered with a functional abdominal pain diagnosis were approached when they were symptomatic to complete the questionnaire (maximum 18 points). Responders who scored at least the 10-point cutoff value (sensitivity, 0.94; specificity, 0.92) underwent a diagnostic evaluation to establish their final diagnosis. The main outcome was the presence and prevalence of ACNES in a group of symptomatic patients diagnosed with functional abdominal pain. Of 535 patients, 304 (57%) responded; 167 subjects (31%) recently reporting symptoms completed the questionnaire. Of 23 patients who scored above the 10-point cutoff value, 18 were available for a diagnostic evaluation. In half of these subjects (n = 9) functional abdominal pain (including IBS) was confirmed. However, the other 9 patients were suffering from abdominal wall pain syndrome, 6 of whom were diagnosed with ACNES (3.6% prevalence rate of symptomatic subjects; 95% confidence interval, 1.7-7.6), whereas the remaining 3 harbored a painful lipoma, an abdominal herniation, and a painful scar. A clinically relevant portion of patients previously diagnosed with functional abdominal pain syndrome in a primary care environment suffers from an abdominal wall pain syndrome such as ACNES.

    Full Text Available "Peritonitis fibrosa incapsulata", first described in 1907, is a condition characterized by encasement of the bowel with a thick fibrous membrane. This condition was renamed as "abdominal cocoon" in 1978. It presents as small bowel obstruction clinically. 35 cases of abdominal cocoon have been reported in the literature over the last three decades. Abdominal cocoon is more common in adolescent girls from tropical countries. Various etiologies have been described, including tubercular. It is treated surgically by releasing the entrapped bowel.

  3. Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

Nozick se basa en la teoría económica para representar a los grupo como competidores en un mercado que vende protección y que resulta, de manera contraintuitiva, en un monopolio. En Colombia, muchos sienten que las cuestiones de vida o muerte no pasan por el Estado y que han de atenerse a la oferta de protección de distintas agencias armadas para intentar, mediantes ensayos e interacciones con ellas y con el Estado, cierto orden social local. El artículo propone alternativas conjeturables sobre el tipo de arden que podría resultado de confrontaciones violentas no ajenas a la utopía.

    Despite the intuitive association of biomass with developing countries, industrialized nations have experienced in the last years a huge increasing in the use and consideration of biomass as strategic energy source. To this new energy policy in developed countries has contributed the need of diversifying the sources of fuel supply, the need of fighting against the increment of greenhouse effect gas emissions to the atmosphere, and the growing price of fossil fuels.

    Full Text Available The substantial increase in vegetable product losses are due to improper practices at the time of harvest and those derived from the conditioning and subsequent treatments that impact significantly on its quality characteristics. These also affect the profitability of a sector that is called to strengthen the feeding of humanity, arousing great concern among supply chains, to define strategies to minimize impacts and strengthen competitiveness in increasingly demanding markets. Researchers have been concerned about the development of friendly environmental techniques that allow the use of natural materials such as polysaccharides, proteins, lipids and the mixture of these compounds. These are applied as edible coatings on fruits and vegetables. This process controls the growth of pathogenic organisms and deteriorative action of external agents. These agents cause defects in ripening. The goal is to prolong their lifespan by reducing the transfer of gases and water vapor and offer fresh looking products, with high nutritional quality, free of pathogens.

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

    Functional abdominal pain syndrome (FAPS) differs from the other functional bowel disorders; it is less common, symptoms largely are unrelated to food intake and defecation, and it has higher comorbidity with psychiatric disorders. The etiology and pathophysiology are incompletely understood. Because FAPS likely represents a heterogeneous group of disorders, peripheral neuropathic pain mechanisms, alterations in endogenous pain modulation systems, or both may be involved in any one patient. The diagnosis of FAPS is made on the basis of positive symptom criteria and a longstanding history of symptoms; in the absence of alarm symptoms, an extensive diagnostic evaluation is not required. Management is based on a therapeutic physician-patient relationship and empirical treatment algorithms using various classes of centrally acting drugs, including antidepressants and anticonvulsants. The choice, dose, and combination of drugs are influenced by psychiatric comorbidities. Psychological treatment options include psychotherapy, relaxation techniques, and hypnosis. Refractory FAPS patients may benefit from a multidisciplinary pain clinic approach.

  16. Hypochondria as an actual neurosis.

    Science.gov (United States)

    Nissen, Bernd

    2017-09-27

    Freud defined hypochondria as an actual neurosis. In this paper the actual neurosis will be interpreted as unbound traumatic elements which threaten the self. In severe hypochondria, breakdowns have occurred, as outlined by Winnicott. The nameless traumatic elements of the breakdown have been encapsulated. The moment these encapsulated elements are liberated, an actual dynamic takes place which threatens the self with annihilation. Projective identification is not possible because no idea of containment exists. The self tries to evacuate these elements projectively, thus triggering a disintegrative regression. However, the object of this projection, which becomes a malign introject, is felt to remove the remaining psychical elements, forcing the worthless residue back into the self. In a final re-introjection, the self is threatened by unintegration. To save the self, these elements are displaced into an organ which becomes hypochondriacal, an autistoid object, protecting itself against unintegration and decomposition. An autistoid dynamic develops between the hypochondriac organ, the ego and the introject. Two short clinical vignettes illustrate the regressive dynamical and metapsychological considerations.

    Elephantiasis is a well-known condition in dermatology usually affecting the legs and external genitalia. It is characterized by chronic inflammation and obstruction of the lymphatic channels and by hypertrophy of the skin and subcutaneous tissues. The etiology is either idiopathic or caused by a variety of conditions such as chronic filarial disease, leprosy, leishmaniasis, and chronic recurrent cellulites. Elephantiasis of the abdominal wall is very rare. A complete review of the English and French literature showed only two cases reported in 1966 and 1973, respectively. We report a third case of abdominal elephantiasis and we briefly review this entity. We present the case of a 51-year-old woman who had progressively developed an enormous pediculated abdominal mass hanging down her knees. The skin was thickened, hyperpigmented, and fissured. She had a history of multiple abdominal cellulites. She underwent an abdominal lipectomy. Histopathology of the specimen confirmed the diagnosis of abdominal elephantiasis. Abdominal elephantiasis is a rare disease that represents end-stage failure of lymph drainage. Lipectomy should be considered in the management of this condition.

  3. Penetrating abdominal trauma.

    1989-08-01

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

  4. Economics of abdominal wall reconstruction.

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    A previously healthy 3-week-old boy presented with 5 hours of marked fussiness, abdominal distention, and poor feeding. He was afebrile and well perfused. His examination was remarkable for localized abdominal tenderness and distention. He was referred to the emergency department in which an abdominal radiograph revealed gaseous distention of the bowel with a paucity of gas in the pelvis. Complete blood cell count and urinalysis were unremarkable. His ongoing fussiness and abnormal physical examination prompted consultation with surgery and radiology. Our combined efforts ultimately established an unexpected diagnosis. Copyright © 2017 by the American Academy of Pediatrics.

  6. How People Actually Use Thermostats

    Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving user interfaces in PTs.

  7. Analysis of tumor-like shadows on abdominal plain x-ray film

    International Nuclear Information System (INIS)

    Hayashi, Hidehiro; Hiraki, Yoshio; Hashimoto, Keizi

    1986-01-01

    We found tumor-like shadows in the upper abdomen in 93 cases out of 400 abdominal plain films, although none of these 93 cases actually had a tumor. We analyzed these tumor-like shadows by computed tomography. For each of the 400 cases we measured the width of flank stripe on the abdominal plain film. Most of the tumor-like shadows in the left upper abdomen were gastric fundus, but it was significant for evaluating plain abdominal film that other organs such as a part of the left lobe of the liver, the upper pole of the left kidney, and a part of the spleen formed tumor-like shadows. The most important factors forming tumor-like shadows on plain abdominal film are the fat volume of the abdominal cauity as well as the fraciform ligament and alterations in the shape and volume of organs such as occur in liver cirrhosis.

    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer. 2014 BMJ Publishing Group Ltd.

En primer lugar, se describe la comunidad de usuarios a nivel global, focalizando en el uso actual que el software ha alcanzado en Argentina: la cantidad de implementaciones disponibles, su evolución, el tipo, tamaño y variedad de los desarrollos existentes, así como su aplicación a la gestión de repositorios digitales de ciencia y tecnología en el ámbito de las instituciones científicas, tecnológicas y de educación superior en Argentina. En segundo lugar, se detallan las acciones llevadas a cabo a partir de la creación del Centro Nacional de Promoción de Greenstone en Argentina en 2009. Datos recabados en encuestas realizadas permitieron observar que las razones predominantes para elegir esta plataforma fueron, entre otras, su facilidad de instalación y configuración, su bajo nivel de requerimiento tecnológico, la generalizada escasez de recursos humanos dedicados a esta actividad, y la complejidad que presentaban los softwares alternativos existentes en ese momento. A lo largo de estos 8 años, tanto los repositorios digitales como los sistemas que los soportan evolucionaron drásticamente, modificando el escenario actual. Paralelamente, en 2016 la nueva versión mayor de Greenstone implementó una reingeniería completa del software para su adaptación a las tecnologías en uso: XML, XSLT, Web-services y Java. Como consecuencia de esto, la comunidad de desarrollo local se plantea nuevos desafíos para la migración de las bibliotecas digitales y repositorios implementados con versiones anteriores.

    2012-06-01

    This review will examine the current evidence regarding pediatric blunt abdominal trauma and the physical exam findings, laboratory values, and radiographic imaging associated with the diagnosis of intra-abdominal injuries (IAI), as well as review the current literature on pediatric hollow viscus injuries and emergency department disposition after diagnosis. The importance of the seat belt sign on physical examination and screening laboratory data remains controversial, although screening hepatic enzymes are recommended in the evaluation of nonaccidental trauma to identify occult abdominal organ injuries. Focused Assessment with Sonography for Trauma (FAST) has modest sensitivity for hemoperitoneum and IAI in the pediatric trauma patient. Patients with concern for undiagnosed IAI, including bowel injury, may be considered for hospital admission and serial abdominal exams without an increased risk of complications, if an exploratory laparotomy is not performed emergently. Although the FAST exam is not recommended as the sole screening tool to rule out IAI in hemodynamically stable trauma patients, it may be used in conjunction with the physical exam and laboratory findings to identify children at risk for IAI. Children with a normal physical exam and normal abdominal CT may not require routine hospitalization after blunt abdominal trauma.

También el concepto de globalización comparte las características citadas previamente ya que se usa para denominar demasiadas cosas, pero aquí lo entendemos como interconexiones económicas, sociales, culturales y políticas, las redes conformadas por todo este entramado de fenómenos sociales y los procesos que muchas veces trascienden las fronteras nacionales.

    Abdominal hernias are a common clinical problem Clinical diagnosis of abdominal hernias can sometimes be challenging, particularly in obese patients or patients with previous abdominal surgery. CT scan of the abdomen allows visualization of hernias and their contents and the differentiation from other masses of the abdominal wall such as tumors, hematomas and abscesses. Moreover, CT may identify complications such as incarceration, bowel obstruction, volvulus and strangulation. This study illustrates the CT scan findings observed in different types of abdominal wall hernias. (author)

One of the aims we try to attain is a necessary theoretical and practical retrieval of politics along with culture and ethics in the public field. As against the prevailing untrammelled power of economics -in particular its purportedly one version, namely «scientific capitalism» and the quite lopsided globalization- it becomes mandatory to completely take into account the view-point of general interests (both national and transnational, universal; and, within that framework, legitimate individual interests, mainly those of broad social sections least endowed with bargaining leverage and resources. The ground for those good reasons of state (and reasons, too, for a civil society critically harmonized with the state lies in an ethics of enlightened values of freedom, equality and brotherhood (solidarity, as well as of such security as stems from social cohesion (a conjunction of justice and efficiency.

    Frente a la mala «Razón de Estado», del pasado y del presente, se alegan aquí algunas de las posibles y potenciales buenas razones del Estado, también como exigencias válidas para el futuro. Con ello se pretende coadyuvar a una imprescindible recuperación teórica y práctica de la política y, con ella, de la cultura y de la ética en el espacio público. Ante el actual poder omnimodo e «incontrolado» de la economía, de su versión pretendidamente única, la del «capitalismo científico» y la muy desigual «globalización», se hace necesario tomar completamente en serio la perspectiva de los intereses generales (nacionales y transnacionales, universales: y, dentro de ellos, los legítimos intereses individuales y, en especial, los de aquellos amplios sectores sociales dotados de muchos menos poderes y posibilidades.

    The most actual goals of geoethics have been formulated as results of the International Conference on Geoethics (October 2013) held at the geoethics birth-place Pribram (Czech Republic): In the sphere of education and public enlightenment an appropriate needed minimum know how of Earth sciences should be intensively promoted together with cultivating ethical way of thinking and acting for the sustainable well-being of the society. The actual activities of the Intergovernmental Panel of Climate Changes are not sustainable with the existing knowledge of the Earth sciences (as presented in the results of the 33rd and 34th International Geological Congresses). This knowledge should be incorporated into any further work of the IPCC. In the sphere of legislation in a large international co-operation following steps are needed: - to re-formulate the term of a "false alarm" and its legal consequences, - to demand very consequently the needed evaluation of existing risks, - to solve problems of rights of individuals and minorities in cases of the optimum use of mineral resources and of the optimum protection of the local population against emergency dangers and disasters; common good (well-being) must be considered as the priority when solving ethical dilemmas. The precaution principle should be applied in any decision making process. Earth scientists presenting their expert opinions are not exempted from civil, administrative or even criminal liabilities. Details must be established by national law and jurisprudence. The well known case of the L'Aquila earthquake (2009) should serve as a serious warning because of the proven misuse of geoethics for protecting top Italian seismologists responsible and sentenced for their inadequate superficial behaviour causing lot of human victims. Another recent scandal with the Himalayan fossil fraud will be also documented. A support is needed for any effort to analyze and to disclose the problems of the deformation of the contemporary

    Objective: To evaluate abdominal imaging in AIDS. Methods: The imaging examinations (including US, CT and MR) of 6 patients with AIDS associated abdominal foci were analysed retrospectively. All the cases were performed US, and CT scan, of which 4 performed enhanced CT scan and 1 with MR. Results: Abdominal tuberculosis were found in 4 patients, including abdominal lymph nodes tuberculosis (3 cases) and pancreatic tuberculosis (1 case). The imaging of lymph nodes tuberculosis typically showed enlarged peripheral tim enhancement with central low-attenuation on contrast-enhanced CT. Pancreatic tuberculosis demonstrated low-attenuation area in pancreatic head and slightly peripheral enhancement. Disseminated Kaposi's sarcoma was seen in 1 case: CT and MRI scan demonstrated tumour infiltrated along hepatic portal vein and bronchovascular bundles. Pelvic tumor was observed in 1 case: CT scan showed large mass with thick and irregular wall and central low attenuation liquefacient necrotic area in the pelvic cavity. Conclusion: The imaging findings of AIDS with abdominal foci is extraordinarily helpful to the diagnosis of such disease. Tissue biopsy is needed to confirm the diagnosis. (authors)

    Full Text Available Resumen: El presente artículo analiza y cuestiona la situación actual que atraviesan los centros y museos de arte contemporáneo, a través de un estudio pormenorizado de las transformaciones más destacadas que se han ido dando en los últimos cuarenta años. Donde hemos pasado, a partir del inicio del postmodernismo, del fenómeno “efecto museo” y proliferación memorística acrecentada en pleno boom económico, a nuevos tiempos de incertidumbre donde muchas instituciones museísticas de nuestro país, ven afectadas sus colecciones por los recortes y ajustes presupuestarios generales del Estado, aumentando de esta manera el peligro de la defensa del programa y la disminución de la actividad de estos espacios expositivos que, asimismo, sufren modificaciones constantes, que necesitan adaptarse a los nuevos tiempos y a las propuestas emergentes de los artistas. Reformulando el museo en crisis, contribuiremos a la discusión introduciendo algunos anomalías y ciertas cuestiones sobre el tema. Como es por ejemplo la actual crisis económica y financiera, que pone en peligro tanto la supervivencia de muchos centros culturales como la investigación de nuestro patrimonio artístico y cultural y, por consiguiente, la amenaza de no poder recuperar nuestra memoria histórica.

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa

    2008-01-01

    Imaging is often a fundamental part in the evaluation of an injured or ill child. A variety of imaging modalities (radiography, angiography/fluoroscopy, sonography, CT, magnetic resonance imaging and scintigraphy) are among the options. CT is worth focused attention because of its usefulness in a variety of emergency department settings, its increasing use, and its potential radiation risks. CT plays an important role in the evaluation of traumatic and nontraumatic abdominal emergencies in children. Therefore, the goal of this paper is to review current imaging approaches and controversies in the evaluation of common acute abdominal emergencies. Through discussion of various modalities, especially CT in evaluation of abdominal pain and trauma, the relative advantages and disadvantages including radiation risk will be reviewed. (orig.)

    Simple abdomen film has played an important role in decision of emergency operations in patients with the abdominal trauma. Nowadays, it still acts as a primary and inevitable processes in emergency condition. At the Department of Radiology, Hanil Hospital, 70 patients, who were laparotomied due to penetrating or nonpernetraing abdominal trauma, were observed and analyzed with simple abdomen film after comparison with the operative findings. The results are as follows: 1. Most frequent age distribution was 10 to 39 years and marked 70%. Male was in 90% incidence. 2. Penetrating injury largely involved the small bowel and abdominal wall. Non-penetrating injury usually involved the spleen, small bowel, liver, kidney, pancreas, duodenum. 3. Single organ injury occurred in higher incidence at the small bowel and abdominal wall. Multiple organ injury occurred in higher incidence at the spleen, liver, kidney and pancreas. 4. Organ distribution was 26% in spleen, 22% in small bowel, 14% in liver, 11% in abdominal wall. 7% in pancreas, 7% in kidney. 5% in duodenum, 4% in GB and CBD, 2% in diaphragm, 2% in colon, and 1% in stomach. 5. The specific roentgen findings and their frequency which useful in differential diagnosis at abdominal trauma, were as follows: a) flank fluid; Detectable possibility was 71% in liver laceration, 69% in spleen laceration and 57% in pancreas laceration. b) ipsilateral psoas shadow obliteration; Detectable possibility was 57% in liver laceration, 57% in kidney laceration and 46% in spleen laceration. c) free air; Detactable possibility was 60% in duodenal perforation, and 36% in peroration of upper part of small bowel. d) Reflex ileus; Detectable possibility was 64% in small bowel, 50% in liver laceration and 35% in spleen laceration. e) rib fracture; Detactable possibility was 36% in liver laceration and 23% in spleen laceration. f) pleural effusion; Detectable possibility was 29% in liver laceration and 27% in spleen laceration

    Penetrating abdominal injuries have been traditionally managed by routine laparotomy. New understanding of trajectories, potential for organ injury, and correlation with advanced radiographic imaging has allowed a shift towards non-operative management of appropriate cases. Although a selective approach has been established for stab wounds, the management of abdominal gunshot wounds remains a matter of controversy. In this chapter we describe the rationale and methodology of selecting patients for non-operative management. We also discuss additional controversial issues, as related to antibiotic prophylaxis, management of asymptomatic thoracoabdominal injuries, and the use of colostomy vs. primary repair for colon injuries.

    2005-08-01

    Abdominal surgery in foals under 30 days old has become more common with improved neonatal care. Early recognition of a foal at risk and better nursing care have increased the survival rates of foals that require neonatal care. The success of improved neonatal care also has increased the need for accurate diagnosis and treatment of gastrointestinal, umbilical, and bladder disorders in these foals. This chapter focuses on the early and accurate diagnosis of specific disorders that require abdominal exploratory surgery and the specific treatment considerations and prognosis for these disorders.

    The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

    Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations. We present an interesting case of secondary implantation of a tubal ectopic pregnancy to highlight the appendix as a possible secondary implantation site after a tubal ectopic pregnancy.

  16. Torsion of abdominal appendages presenting with acute abdominal pain

    Diseases of abnormal appendages are rare causes of abdominal pain in all age groups. Nine patients with torsion and infraction of abdominal appendages were retrospectively reviewed. Four patients had torsion and infarction of the appendices epiploicae, four patients had torsion and infarction of the falciform ligament. The patient with falciform ligament disease represents the first reported case of primary torsion and infarction of the falciform ligament, and the patient with the transverse colon epiplocia represents the first reported case of vibration-induced appendix epiplocia torsion and infarction. The patient with the falciform ligament disease presented with a tender upper abdominal mass and the remaining patients were operated upon with the preoperative diagnosis of acute appendicitis. The presence of normal appendix with free serosanguinous fluid in the peritoneal cavity should raise the possibility of a disease and calls for further evaluation of the intra-abdominal organs. If the diagnosis is suspected preoperatively, CT scan and ultrasound may lead to a correct diagnosis and possibly conservative management. Laparoscopy is playing an increasing diagnostic and therapeutic role in such situations. (author)

El debate en torno al corporativismo, según el autor, se centra principalmente en las políticas de concertación surgidas despúes de la Segunda Guerra Mundial. Se evalúa la principal bibliografía sobre el tema publicada en Inglaterra, Francia, Italia, Portugal, España y Estados Unidos desde 1974 hasta 1985, y se organiza en torno a los siguientes temas principales : los orígenes sociales del corporativismo ; definciones y tipos de corporativismo; causas y condiciones de las tendencias actuales del corporativismo; corporativismo, estado y democracia ; la inestabilidad del corporativismo. Un visión liberal del concepto lo ve como un intento de aproximación racional a la resolución de conflictos sociales y contradicciones existentes entre los diversos grupos de interés. Un punto de vista más radical del corporativismo señala el modo mediante el cual el capitalismo avanzado garantiza su estabilidad mediante la subordinación de las clases sociales a los "contratos sociales corporativos". Según el autor, se puede concluir que el "corporativismo" es una amplia tendencia a través de la cual la desigualdad social y los conflictos sociales se articulan en las sociedades avanzadas capitalistas.

    Full Text Available Traumatic abdominal wall hernia is a rare type of hernia, which follows blunt trauma to the abdomen, where disruption of the musculature and fascia occurs with the overlying skin remaining intact. Diagnosis of this problem is very difficult and delayed. Traumatic hernia is often diagnosed during laparatomy or laparascopy, but CT scan also has a role in distinguishing this pathology. Delay in diagnosis is very dangerous and can result in gangrene and necrosis of the organs in the hernia. The case report of a 35 years old man with liftruck blunt trauma is reported. His vital signs were stable. On physical examination, tenderness of RUQ was seen. He underwent Dpl for suspected hemoprotein. Dpl was followed up by laparatomy. Laparatomy revealed that the transverse and ascending colon partially herniated in the abdominal wall defect. The colon was reduced in the abdomen and repair of abdominal hernia was done. The patient was discharged after 5 day. The etiology, pathogenesis and management are discussed.

    To report our experience with erosion of permanent suture or mesh material after abdominal sacrocolpopexy. A retrospective chart review was performed to identify patients who underwent sacrocolpopexy by the same surgeon over 8 years. Demographic data, operative notes, hospital records, and office charts were reviewed after sacrocolpopexy. Patients with erosion of either suture or mesh were treated initially with conservative therapy followed by surgical intervention as required. Fifty-seven patients underwent sacrocolpopexy using synthetic mesh during the study period. The mean (range) postoperative follow-up was 19.9 (1.3-50) months. Seven patients (12%) had erosions after abdominal sacrocolpopexy with two suture erosions and five mesh erosions. Patients with suture erosion were asymptomatic compared with patients with mesh erosion, who presented with vaginal bleeding or discharge. The mean (+/-standard deviation) time to erosion was 14.0+/-7.7 (range 4-24) months. Both patients with suture erosion were treated conservatively with estrogen cream. All five patients with mesh erosion required transvaginal removal of the mesh. Mesh erosion can follow abdominal sacrocolpopexy over a long time, and usually presents as vaginal bleeding or discharge. Although patients with suture erosion can be managed successfully with conservative treatment, patients with mesh erosion require surgical intervention. Transvaginal removal of the mesh with vaginal advancement appears to be an effective treatment in patients failing conservative management.

  19. Appendicitis following blunt abdominal trauma.

    2017-09-01

    Appendicitis is a frequently encountered surgical problem in the Emergency Department (ED). Appendicitis typically results from obstruction of the appendiceal lumen, although trauma has been reported as an infrequent cause of acute appendicitis. Intestinal injury and hollow viscus injury following blunt abdominal trauma are well reported in the literature but traumatic appendicitis is much less common. The pathophysiology is uncertain but likely results from several mechanisms, either in isolation or combination. These include direct compression/crush injury, shearing injury, or from indirect obstruction of the appendiceal lumen by an ileocecal hematoma or traumatic impaction of stool into the appendix. Presentation typically mirrors that of non-traumatic appendicitis with nausea, anorexia, fever, and right lower quadrant abdominal tenderness and/or peritonitis. Evaluation for traumatic appendicitis requires a careful history and physical exam. Imaging with ultrasound or computed tomography is recommended if the history and physical do not reveal an acute surgical indication. Treatment includes intravenous antibiotics and surgical consultation for appendectomy. This case highlights a patient who developed acute appendicitis following blunt trauma to the abdomen sustained during a motor vehicle accident. Appendicitis must be considered as part of the differential diagnosis in any patient who presents to the ED with abdominal pain, including those whose pain begins after sustaining blunt trauma to the abdomen. Because appendicitis following trauma is uncommon, timely diagnosis requires a high index of suspicion. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available La salud de las personas ha mejorado a lo largo del siglo xx, al mismo tiempo que se consolidaba el Estado del bienestar. Este trabajo explora la relación actual del Estado del bienestar y la salud pública. Las funciones esenciales de la salud pública se ejercen como parte del Estado, y su principal reto en la actualidad es conseguir que la salud sea protegida y promocionada en las diferentes políticas públicas, entre otras las de empleo. Los resultados de los estudios que valoran el efecto sobre la salud de los distintos tipos de Estado del bienestar son contradictorios, pero cuando se valora el impacto de políticas concretas, como por ejemplo el subsidio de desempleo, los resultados son positivos y consistentes. Sin embargo, la actual crisis del Estado del bienestar dificulta su continuidad, en gran medida por los cambios en el mercado de trabajo, con empleos más flexibles e inseguros.

  5. Increased pressure within the abdominal compartment: intra-abdominal hypertension and the abdominal compartment syndrome.

    Roberts, Derek J; Ball, Chad G; Kirkpatrick, Andrew W

    2016-04-01

    This article reviews recent developments related to intra-abdominal hypertension (IAH)/abdominal compartment syndrome (ACS) and clinical practice guidelines published in 2013. IAH/ACS often develops because of the acute intestinal distress syndrome. Although the incidence of postinjury ACS is decreasing, IAH remains common and associated with significant morbidity and mortality among critically ill/injured patients. Many risk factors for IAH include those findings suggested to be indications for use of damage control surgery in trauma patients. Medical management strategies for IAH/ACS include sedation/analgesia, neuromuscular blocking and prokinetic agents, enteral decompression tubes, interventions that decrease fluid balance, and percutaneous catheter drainage. IAH/ACS may be prevented in patients undergoing laparotomy by leaving the abdomen open where appropriate. If ACS cannot be prevented with medical or surgical management strategies or treated with percutaneous catheter drainage, guidelines recommend urgent decompressive laparotomy. Use of negative pressure peritoneal therapy for temporary closure of the open abdomen may improve the systemic inflammatory response and patient-important outcomes. In the last 15 years, investigators have better clarified the pathogenesis, epidemiology, diagnosis, and appropriate prevention of IAH/ACS. Subsequent study should be aimed at understanding which treatments effectively lower intra-abdominal pressure and whether these treatments ultimately affect patient-important outcomes.

  8. Evaluation of the levels of metalloproteinsase-2 in patients with abdominal aneurysm and abdominal hernias.

    2013-05-01

    Abdominal aortic aneurysms and abdominal hernias become an important health problems of our times. Abdominal aortic aneurysm and its rupture is one of the most dangerous fact in vascular surgery. There are some theories pointing to a multifactoral genesis of these kinds of diseases, all of them assume the attenuation of abdominal fascia and abdominal aortic wall. The density and continuity of these structures depend on collagen and elastic fibers structure. Reducing the strength of the fibers may be due to changes in the extracellular matrix (ECM) by the proteolytic enzymes-matrix metalloproteinases (MMPs) that degrade extracellular matrix proteins. These enzymes play an important role in the development of many disease: malignant tumors (colon, breast, lung, pancreas), cardiovascular disease (myocardial infarction, ischemia-reperfusion injury), connective tissue diseases (Ehler-Danlos Syndrome, Marfan's Syndrome), complications of diabetes (retinopathy, nephropathy). One of the most important is matrix metalloproteinase-2 (MMP-2). The aim of the study was an estimation of the MMP-2 blood levels in patients with abdominal aortic aneurysm and primary abdominal hernia, and in patients with only abdominal aortic aneurysm. The study involved 88 patients aged 42 to 89 years, including 75 men and 13 women. Patients were divided into two groups: patients with abdominal aortic aneurysm and primary abdominal hernia (45 persons, representing 51.1% of all group) and patients with only abdominal aortic aneurysm (43 persons, representing 48,9% of all group). It was a statistically significant increase in MMP-2 blood levels in patients with abdominal aortic aneurysm and primary abdominal hernia compared to patients with only abdominal aortic aneurysm. It was a statistically significant increase in the prevalence of POCHP in patients with only abdominal aortic aneurysm compared to patients with abdominal aortic aneurysm and primary abdominal hernia.

The real etiology and pathogenesis of IgG4-RD is still not clearly understood. Moreover the exact role of IgG4 or IgG4-positive plasma cells in this disease has not yet been elucidated. only some inconsistent biological features such as hypergammaglobulinemia or hypocomplementemia support the autoimmune nature of the disease process. various names have been ascribed to this clinicopathological entity including IgG4-related sclerosing disease, IgG4-related systemic sclerosing disease, IgG4-related disease, IgG4-related autoimmune disease, hyper-IgG4 disease and IgG4-related systemic disease. The extrapancreatic lesions of IgG4-RD also exhibit the same characteristic histologic features including dense lymphoplasmacytic infiltrate, massive storiform fibrosis, and obliterative phlebitis as seen in IgG4-related pancreatitis. Abdominal manifestations include the following organs/systems: Bile ducts: Sclerosing cholangitis; Gallbladder and liver: Acalculous sclerosis cholecytitis with diffuse wall thickening; hepatic inflammatory pseudotumorts; Kidneys: round or wedge-shaped renal cortical nodules, peripheral cortical; lesions, mass like lesions or renal pelvic involvement; Prostate, urethra, seminal vesicle, vas deferens, uterine cervix; Autoimmune prostatitis; Retroperitoneum: Retroperitoneal fibrosis. thin or mildly thick homogeneous soft tissue lesion surrounding the abdominal aorta and its branches but also bulky masses causing hydronephroureterosis; Mesentery: Sclerosing mesenteritis usually involving the root of the mesentery; Bowel: Inflammatory bowel diseases mimicking Crohn’s disease or ulcerative colitis. various types of sclerosing nodular lesions of the bowel wall; Stomach: Gastritis, gastric ulcers and focal masses mimicking submucosal tumor; omentum: Infiltration mimicking

    Acute abdominal pain is a common clinical condition. Clinical signs and symptoms can be difficult to interpret, and diagnostic imaging may help to identify intra-abdominal disease. Conventional X-ray, ultrasound (US) and computed tomography (CT) of the abdomen vary in usability between common surgical causes of acute abdominal pain. Overall, conventional X-ray cannot confidently diagnose or rule out disease. US and CT are equally trustworthy for most diseases. US with subsequent CT may enhance diagnostic precision. Magnetic resonance seems promising for future use in acute abdominal imaging.

In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management.

    One of the key challenges in perioperative care is to reduce postoperative morbidity and mortality. Patients who develop postoperative morbidity but survive to leave hospital have often reduced functional independence and long-term survival. Mechanical ventilation provides a specific example that may help us to shift thinking from treatment to prevention of postoperative complications. Mechanical ventilation in patients undergoing surgery has long been considered only as a modality to ensure gas exchange while allowing maintenance of anesthesia with delivery of inhaled anesthetics. Evidence is accumulating, however, suggesting an association between intraoperative mechanical ventilation strategy and postoperative pulmonary function and clinical outcome in patients undergoing abdominal surgery. Non-protective ventilator settings, especially high tidal volume (VT) (>10-12mL/kg) and the use of very low level of positive end-expiratory pressure (PEEP) (PEEPventilator-associated lung injury in patients with healthy lungs. Stimulated by previous findings in patients with acute respiratory distress syndrome, the use of lower tidal volume ventilation is becoming increasingly more common in the operating room. However, lowering tidal volume, though important, is only part of the overall multifaceted approach of lung protective mechanical ventilation. In this review, we aimed at providing the most recent and relevant clinical evidence regarding the use of mechanical ventilation in patients undergoing abdominal surgery.

    To analyze the ultrasonography findings in abdomen in the AIDS patients in our hospital, as well as the indications for this exploration, assessing the role of abdominal ultrasound (AU). The ultrasonographic and clinical findings in 527 patients who underwent a total of 715 explorations between 1992 and 1996 were studied. Hepatomegaly and/or splenomegaly, usually homogeneous, were observed in nearly half of the studies (45%); one third of the patients with marked splenomegaly presented visceral leishmaniasis. Focal lesions in liver and/or spleen, corresponding to angiomas, abscesses, lymphomatous lesions and metastasis, were detected in 5.7% of the explorations. Thirty-five percent of the AU revealed the presence of lymphadenopathy; nodes measuring over 2.5 cm were usually related to potential treatable infection or neoplasm. Thickening of the gallbladder wall did not usually indicate the presence of acute cholecystitis unless Murphy''s sign was also detected. Bile duct dilation and wall thickening was related to opportunistic cholangitis, and the increase in the echogenicity of the renal parenchyma was linked to AIDS-related nephropathy. Despite the fact that many of findings with AU are nonspecific, we consider that this approach should be the principal diagnostic technique in AIDS patients with suspected abdominal pathology or fever of unknown origin.

    The actual nuclear R and D issues require new technologies and continuous progress in order to find adequate and effective solutions in sustained and increasing energy demand. The current tendency in energy consumption and occurring of large consumers, especially from Asian countries, imposes finding new means for energy clean, large scale and sustained production. NPPs reliability and availability were permanently monitored and improved; in the mean time the safety of the nuclear energy production was under surveillance. Corresponding development of the new technologies and discovery of improved materials and adequate technological processes offers the possibilities for appropriate implementation and use of them in the NPPs systems configuration and functioning/operation. The modern technologies and scientific discoveries, also the international cooperation, offer the opportunities to brake the actual barriers in order to cumulate and use advanced energy production processes in finding new energy sources and to build improved, reliable and safety power plants. The monitoring systems, intelligent sensors and intelligent SSCs, nanotechnologies and and modern and intelligent materials constitute the main reasons in improvement of the NPPs systems configuration and processes. The paper presents: - The state of the art in the level of actual and useful technologies for nuclear power systems development; - The actual technological limits that need to be over passed for NPPs systems improvements; - The main systems that need improvement and reconfiguration for actual NPPs development and increase in efficient operation, appropriate availability and total safety; - The actual energy production issues; - The key arguments in sustaining the R and D new NPPs systems development; - Future trends in NPPs development; - The limitations in industrial processes knowledge and use.

    Abdominal wall injuries occur in nearly one of 10 patients coming to the emergency department after nonpenetrating trauma. Injuries range from minor, such as abdominal wall contusion, to severe, such as abdominal wall rupture with evisceration of abdominal contents. Examples of specific injuries that can be detected at cross-sectional imaging include abdominal muscle strain, tear, or hematoma, including rectus sheath hematoma (RSH); traumatic abdominal wall hernia (TAWH); and Morel-Lavallée lesion (MLL) (closed degloving injury). These injuries are often overlooked clinically because of (a) a lack of findings at physical examination or (b) distraction by more-severe associated injuries. However, these injuries are important to detect because they are highly associated with potentially grave visceral and vascular injuries, such as aortic injury, and because their detection can lead to the diagnosis of these more clinically important grave traumatic injuries. Failure to make a timely diagnosis can result in delayed complications, such as bowel hernia with potential for obstruction or strangulation, or misdiagnosis of an abdominal wall neoplasm. Groin injuries, such as athletic pubalgia, and inferior costochondral injuries should also be considered in patients with abdominal pain after nonpenetrating trauma, because these conditions may manifest with referred abdominal pain and are often included within the field of view at cross-sectional abdominal imaging. Radiologists must recognize and report acute abdominal wall injuries and their associated intra-abdominal pathologic conditions to allow appropriate and timely treatment. © RSNA, 2017.

    To describe the abdominal imaging findings of patients with gastrointestinal Basidiobolus ranarum infection. A literature search was performed to compile the abdominal imaging findings of all reported worldwide cases of gastrointestinal basidiobolomycosis (GIB). In addition, a retrospective review at our institution was performed to identify GIB cases that had imaging findings. A radiologist aware of the diagnosis reviewed the imaging findings in detail. Additional information was obtained from the medical records. A total of 73 GIB cases have been published in the medical literature. The most common abdominal imaging findings were masses in the colon, the liver, or multiple sites and bowel wall thickening. Initially, many patients were considered to have either a neoplasm or Crohn disease. We identified 7 proven cases of GIB at our institution, of which 4 had imaging studies (4 computed tomography [CT] examinations, 4 abdominal radiographs, and an upper gastrointestinal study). Imaging studies showed abnormalities in all 4 cases. Three-fourths of our study patients had an abdominal mass at CT. Two of 3 masses involved the kidneys and included urinary obstruction. All masses showed an inflammatory component with adjacent soft tissue stranding, with or without abscess formation. Radiologists should consider GIB when a patient from an arid climate presents with abdominal pain, weight loss, and an inflammatory abdominal mass on CT. Abdominal masses of the colon or liver, bowel wall thickening, and abscesses are the most common imaging findings.

    2015-01-01

    Abdominal radiography and ultrasonography are commonly used as part of the initial diagnostic plan for cats with nonspecific signs of abdominal disease. This retrospective study compared the clinical usefulness of abdominal radiography and ultrasonography in 105 feline patients with signs of abdominal disease. The final diagnosis was determined more commonly with ultrasonography (59%) compared to radiography (25.7%). Ultrasonography was also able to provide additional clinically relevant information in 76% of cases, and changed or refined the diagnosis in 47% of cases. Based on these findings, ultrasonography may be sufficient as an initial diagnostic test for the investigation of feline abdominal disease. PMID:26483582

As fetal MRI covers a period of more than 20 weeks, which is characterized not only by organ growth, but also by changes and maturation of organ function, a different MR appearance of the fetal abdomen results. This not only applies to the fetal intestines, but also to the fetal liver, spleen, and adrenal glands. Choosing the appropriate sequences, various aspects of age-related and organ-specific function can be visualized with fetal MRI, as these are mirrored by changes in signal intensities. Knowledge of normal development is essential to delineate normal from pathological findings in the respective developmental stages

    Typical automotive related abdominal injuries occur due to contact with the rim of the steering wheel, seatbelt and armrest, however, the rate is less than in other body regions. When solid abdominal organs, such as the liver, kidneys and spleen are involved, the injury severity tends to be higher. Although sled and pendulum impact tests have been conducted using cadavers and animals, the mechanical properties and the tissue level injury tolerance of abdominal solid organs are not well characterized. These data are needed in the development of computer models, the improvement of current anthropometric test devices and the enhancement of our understanding of abdominal injury mechanisms. In this study, a series of experimental tests on solid abdominal organs was conducted using porcine liver, kidney and spleen specimens. Additionally, the injury tolerance of the solid organs was deduced from the experimental data.

Uma delas, minoritária, baseia-se na prerrogativa do Estado na gestão do dia a dia prisional. A outra é relativa à negociação da pacificação do presídio entre o Estado e as lideranças dos presos. Embora, no primeiro caso, a prerrogativa do Estado possa ser vinculada às condições institucionais adequadas e, no segundo (negociação entre o estado e as lideranças dos presos às condições precárias dos presídios, como superlotação, número reduzido de agentes penitenciários, entre outros, a análise apontou que ambas as modalidades traduzem formas de relacionamentos e interações sociais historicamente produzidas entre o Estado e a sociedade, que remetem à fundação da República, recriadas através do habitus dos atores sociais, não se restringindo exclusivamente ao espaço social das prisões.

    Dancers are highly susceptible to musculoskeletal injuries and frequently require interaction with medical professionals. While many dancers have a finely tuned awareness of their bodies, their knowledge of the fundamentals of human anatomy is not uniform. There is a paucity of literature on the benefits of human anatomy education in dancers, though it seems intuitive that there should be a relationship. The purpose of this study was to assess dancers' perceived and actual knowledge of basic musculoskeletal anatomy and its relationship to function. Adult dancers at the undergraduate, pre-professional, and professional levels were surveyed through an anonymous online questionnaire. Questions included demographic information, dance techniques studied, anatomy training, and injury history. Subjects rated their perceived knowledge of anatomy and were tested with 15 multiple-choice questions on basic musculoskeletal anatomy. Four hundred seventy-five surveys were completed. Ordinal regression showed a correlation of perceived to actual knowledge of anatomy (p < 0.001). Factors that correlated with increases in both perceived and actual knowledge of anatomy included having taken an anatomy course of any type (p < 0.001) and increased age (p ≤ 0.001). Years of dance training and professional dancer status both significantly correlated with increased knowledge of anatomy (p < 0.001) but not perceived knowledge. Chi-square analysis showed that dancers with training in either modern or jazz dance had a significantly higher perceived, but not actual, knowledge when compared to those without training in those styles of dance (p < 0.001 and p = 0.011, respectively). In conclusion, dancers generally scored well on questions pertaining to basic musculoskeletal anatomy, and their perception correlated with their actual knowledge of anatomy. Factors that contribute to dancers' knowledge of anatomy include age, years of experience, professional dancer status, and anatomy training.

  11. Actual imaging time in fetal MRI

    Brugger, Peter C.; Prayer, Daniela

    2012-01-01

    Objective: Safety issues in magnetic resonance imaging (MRI) are important, especially in fetal MRI. However, since basic data with respect of the effective exposure time in fetal MRI are not available, this study aimed to determine the actual imaging time during a fetal MRI study. Methods: 100 fetal MRI studies of singleton pregnancies performed on a 1.5 T system were analysed with respect to study duration (from starting the survey scan until the end of study), the number of sequences acquired, and the actual imaging time, which was calculated by adding up scan time of each sequence. Furthermore, each sequence type was analysed regarding the number of acquisitions, specific absorption rates (SAR), and duration. Results: Mean study duration was 34.6 min (range: 14–58 min; standard deviation (SD): 9.7 min), the average number of sequences acquired was 26.6 (range: 11–44, SD: 6.6). Actual scan time averaged 11.4 min (range: 4–19 min, SD: 4.0 min). Ultrafast T2-weighted and steady-state free-precession sequences accounted for 62.3% of actual scan time, and were distributed over the whole duration of the study. Conclusion: Actual imaging time only accounts for 33% of total study time and is not continuous. The remaining time is consumed by the preparation phases of the scanner, and is spent with planning sequences and the eventual repositioning of the coil and/or pregnant woman. These data may help to more accurately estimate the exposure to radiofrequency deposition and noise during fetal MRI studies.

    Full Text Available Resumen: Los controladores PID continúan siendo una solución fiable, robusta, práctica y sencilla para el control de procesos. Actualmente constituyen la primera capa de control de la gran mayoría de las aplicaciones industriales. De ahí que un número importante de trabajos de investigación se han orientado a mejorar su rendimiento y prestaciones. Las líneas de investigación en este campo van desde nuevos métodos de ajuste, pasando por nuevos tipos de estructura hasta metodologías de diseño integrales. Particularizando en el ajuste de parámetros, una de las formas de obtener una solución novedosa consiste en plantear un problema de optimización, el cual puede llegar a ser no-lineal, no-convexo y con restricciones. Dado que los algoritmos evolutivos han mostrado un buen desempeño para solucionar problemas complejos de optimización, han sido utilizados en diversas propuestas relacionadas con el ajuste de controladores PID. Este trabajo muestra un revisión de estas propuestas y las prestaciones obtenidas en cada caso. Así mismo, se identifican algunas tendencias y posibles líneas de trabajo futuras.

    The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) fields. Mobi-Kids, an international study coordinated by CREAL Barcelona, is underway in 15 countries to assess potential effects of childhood and adolescent exposure to electromagnetic fields (EMF) from mobile communications technology (RF and extremely low frequency (ELF) fields) on brain tumour risk. The study aims to recruit over 2,000 cases of brain tumours aged 10 to 24 years and their respective controls (300 cases and 600 controls from Spain). The project builds upon the methodological experience of the INTERPHONE study. Hospital based controls are being selected to reduce potential selection bias related to low response rates of population-based controls, validation of questionnaire responses with recross from network operators will allow characterization of possible recall errors. Extensive work has gone into characterising and modelling ELF and RF exposure from different types of mobile and cordless phones, from different communication systems, and from other environmental sources of EMF. The study will address a public health problem of increasing importance in Spain and provide information on potential health risks from mobile telephone use as well as from EMF in general.

Al comparar los datos de los aborígenes argentinos (AA con otras poblaciones indígenas sudamericanas (IS se observaron similares valores de Gst' a nivel proteico (AA:Gst'=3.6%, IS: Gst'=3.0%-6.0% y más bajos a nivel nuclear (AA: Gst'= 6.0%, IS: Gst'= 11%-13% y mitocondrial (AA: Gst'= 8%, IS: Gst'= 26% -36%. Los valores de Gst' hallados en AA son los más bajos encontrados en IS, lo cual sugiere la existencia de un intenso flujo génico entre los habitantes del norte y del sur del país. Estos resultados parecen corresponderse con la información arqueológica e histórica.

Se tratan los aspectos relacionados con la historia, la aparición de la pandemia, la biología de la enfermedad, la epidemiología, el cuadro clínico, el tratamiento y el pronóstico y la prevención. La gripe A (H1N1 es una pandemia causada por una variante nueva del virus de la Influenza A que ha sufrido cambios antigénicos en la hemaglutinina y la neuraminidasa. Esto hace que la población sea altamente vulnerable a la infección y produce una sobrecarga temporal enorme a los servicios de salud. El virus se trasmite como otros virus Influenza. Su letalidad es similar a la de la influenza estacional, pero puede incrementarse en personas con factores de riesgo y en adultos jóvenes sanos. El asma y el embarazo parecen ser condiciones de base importantes para incrementar la severidad de la infección. Puede existir cierta protección por inmunidad cruzada con cepas que circularon en el pasado. El espectro clínico va desde personas asintomáticas hasta las formas graves que requieren internación en cuidados intensivos, con rápido deterioro hasta llegar a la insuficiencia respiratoria en un plazo de 24 horas. La vacunación durante la pandemia no parece ser suficientemente efectiva. Son necesarios antivirales (oseltamivir y zanamivir, y las medidas preventivas higiénico-sanitarias son muy eficaces.An updated review using the main search motors and international meetings already celebrated related to Influenza A H1N1 pandemics. Items related to the history, the appearance of the pandemics, the biology of the disease, its epidemiology, clinics, treatment, prognosis and prevention. Grippe A H1N1 is a pandemic caused by a new variant of the Influenza A virus that has suffered antigenic changes in haemaglutinin and neuraminidase. This turns populations more susceptible to this infection and produces a temporary burden on the health services. This virus is transmitted like other influenza viruses. Its lethality is similar to that observed for the seasonal influenza, but may be enhanced in people having risk factors and in healthy young adults. Asthma and pregnancy seem to be basic conditions to increase the severity of the infection. Certain degree of protection may exist, due to cross immunity with ancient strains that circulated in the past times. The clinical spectrum goes from asymptomatic people to the most severe forms requiring intensive care, when a rapid deterioration of the health up to reach a respiratory failure in 24 hours. Vaccination during the epidemics seems to be non effective. Antiviral agents (oseltamivir and zanamivir are necessary, and the preventive hygiene-sanitary measures are highly effective.

    Full Text Available Despite their relevance as a source of funding and their chaotic proliferation in recent times, the revenue from the power of Autonomous Communities to create their own taxes is almost testimonial. The regulation of these taxes, scattered and confused, has become a source of multiple legal and political conflicts, which resulted in not always clear and consistent jurisprudence of the Constitutional Court. For that reason, and keeping in mind the limitations that are arriving from the European Union, it is necessary to develop an updated study of that power, and it is the main objective of this work. In particular, an overview of its current status in the different Autonomous Communities will be provided (with special reference to Catalonia.

The recorded families are Iguanidae s.l., Teiidae, Gekkonidae, ?Scincidae, Amphisbaenidae, Boidae, Aniliidae, Colubridae and Viperidae Dinilysiidae from the Late Cretaceous of Patagonia and Palaeopheidae from the Late Eocene of Ecuador are the only known extinct recorded families. The families distribution during the Cretaceous and most of the Tertiary apparently was more extensive than at present, due to more generalized subtropical climatic conditions. The geological events during the Cenozoic would have caused climatic and environmental changes that would have favoured the appeareance of new adaptative types and the restriction in the distribution of many forms.

Those registrations of doubtful assignation or that couldn't be confirmed were not considered in this review. These new registrations are classified in four groups of time that extend from the Late Eocene-Early Oligocene to the Pleistocene-Recent. The evidence shows that the greatest quantity of fossils are concentrated from the Early Miocene to the Middle Miocene reaching 37 (41.5%) genus of a total of 77 and 54 (49.5%) fossil species of a total of 89. It is observed a significant increase in works devoted to paleontology of mammal fossils in Chile between 1981-2008. (Author)

    1980-01-01

    By utilizing a 4.5-second CT (computed tomography) scanner which allows sequential scans the changes of the iodine concentration in abdominal organs can be observed as dynamics reflected in CT number. The abdominal dynamic CT was performed as following method. After performing the preliminary scan 50ml of 60% meglumine iothalamate was rapidly injected intravenously by hands. The sequential scanning was initiated when a half dose of contrast medium was injected. In completion of the 4 sequential scans under arrested respiration the conventional post contrast scanning was performed. The analysis of 112 cases dynamically studied by CT came to the following conclusion. CT number of the abdominal aorta was greatest on the 1st or 2nd scan of the sequential scans (7.5 - 20.5 seconds after initiation of injection). Following this peak formation, CT number of the abdominal aorta declined rapidly due to both prompt diffusion of contrast medium into the extravascular space and dilution by the intravascular fluid. Iodine concentration of the abdominal aorta during the peak period was calculated as 11.3 mg/ml by the present method, being theoretically sufficient for delineation of the vessels smaller than medium size. In the patients with impaired renal function, several characteristic patterns were noted on the dynamics of contrast medium within the abdominal organs. The abdominal dynamic CT was felt to be promissing for evaluation of the renal function. (author)

  9. Review article: the functional abdominal pain syndrome.

    Science.gov (United States)

    Sperber, A D; Drossman, D A

    2011-03-01

    Functional abdominal pain syndrome (FAPS) is a debilitating disorder with constant or nearly constant abdominal pain, present for at least 6 months and loss of daily functioning. To review the epidemiology, pathophysiology and treatment of FAPS. A literature review using the keywords: functional abdominal pain, chronic abdominal pain, irritable bowel syndrome and functional gastrointestinal disorders. No epidemiological studies have focused specifically on FAPS. Estimates of prevalence range from 0.5% to 1.7% and tend to show a female predominance. FAPS pathophysiology appears unique in that the pain is caused primarily by amplified central perception of normal visceral input, rather than by enhanced peripheral stimulation from abdominal viscera. The diagnosis of FAPS is symptom-based in accordance with the Rome III diagnostic criteria. These criteria are geared to identify patients with severe symptoms as they require constant or nearly constant abdominal pain with loss of daily function and are differentiated from IBS based on their non-association with changes in bowel habit, eating or other gut-related events. As cure is not feasible, the aims of treatment are reduced suffering and improved quality of life. Treatment is based on a biopsychosocial approach with a therapeutic patient-physician partnership at its base. Therapeutic options include central nonpharmacological and pharmacological modalities and peripheral modalities. These can be combined to produce an augmentation effect. Although few studies have assessed functional abdominal pain syndrome or its treatment specifically, the treatment strategies outlined in this paper appear to be effective. © 2011 Blackwell Publishing Ltd.

    To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer.

    2014-07-01

    Rupture is the most serious and lethal complication of the abdominal aortic aneurysm. Despite all improvements during the past 50 years, ruptured abdominal aortic aneurysms are still associated with very high mortality. Namely, including patients who die before reaching the hospital, the mortality rate due to abdominal aortic aneurysm rupture is 90%. On the other hand, during the last twenty years, the number of abdominal aortic aneurysms significantly increased. One of the reasons is the fact that in majority of countries the general population is older nowadays. Due to this, the number of degenerative AAA is increasing. This is also the case for patients with abdominal aortic aneurysm rupture. Age must not be the reason of a treatment refusal. Optimal therapeutic option ought to be found. The following article is based on literature analysis including current guidelines but also on my Clinics significant experience. Furthermore, this article show cases options for vascular medicine in undeveloped countries that can not apply endovascular procedures at a sufficient level and to a sufficient extent. At this moment the following is evident. Thirty-day-mortality after repair of ruptured abdominal aortic aneurysms is significantly lower in high-volume hospitals. Due to different reasons all ruptured abdominal aortic aneurysms are not suitable for EVAR. Open repair of ruptured abdominal aortic aneurysm should be performed by experienced open vascular surgeons. This could also be said for the treatment of endovascular complications that require open surgical conversion. There is no ideal procedure for the treatment of AAA. Each has its own advantages and disadvantages, its own limits and complications, as well as indications and contraindications. Future reductions in mortality of ruptured abdominal aortic aneurysms will depend on implementation of population-based screening; on strategies to prevent postoperative organ injury and also on new medical technology

    A wide variety of normal and pathologic factors may induce intraabdominal calcification. In general, the most reliable indication of the cause of a calcification is its location; therefore, if the affected organ can be identified the radiographic diagnosis is often straightforward or, at least, limited to relatively few possibilities. With this principle in mind, a series of patients with abdominal calcification are described for the purpose of illustrating the appearance of calcification of various abdominal organs. In addition, etiology for the calcification in each patient is discussed. Certain extraabdominal calcifications which may be seen on abdominal radiographs are also mentioned

    Cranial and abdominal computerized tomography (CT) was performed in a 10-year-old boy with Wilson's disease complicated by liver cirrhosis. Abdominal CT showed diffuse high density areas over the whole part of the liver propably due to copper sediments, although there was no abnormal cranial CT findings. Decreased high density area of the liver was seen 60 days after the administration of D-penicillamine, suggesting the excretion of copper from the liver. Abdominal CT, as well as cranial CT, may be of help to diagnose Wilson's disease and evaluate therapeutic effects. (Namekawa, K.).

    Sixty-nine patients are presented in whom a substantial error was made on the initial abdominal computed tomography report. Certain features of these errors have been analysed. In 30 (43.5%) a lesion was simply not recognised (error of observation); in 39 (56.5%) the wrong conclusions were drawn about the nature of normal or abnormal structures (error of interpretation). The 39 errors of interpretation were more complex; in 7 patients an abnormal structure was noted but interpreted as normal, whereas in four a normal structure was thought to represent a lesion. Other interpretive errors included those where the wrong cause for a lesion had been ascribed (24 patients), and those where the abnormality was substantially under-reported (4 patients). Various features of these errors are presented and discussed. Errors were made just as often in relation to small and large lesions. Consultants made as many errors as senior registrar radiologists. It is like that dual reporting is the best method of avoiding such errors and, indeed, this is widely practised in our unit. (Author). 9 refs.; 5 figs.; 1 tab

    Full Text Available OBJECTIVE:Patients undergoing abdominal surgery are at risk for pulmonary complications. The principal cause of postoperative pulmonary complications is a significant reduction in pulmonary volumes (FEV1 and FVC to approximately 65-70% of the predicted value. Another frequent occurrence after abdominal surgery is increased intra-abdominal pressure. The aim of this study was to correlate changes in pulmonary volumes with the values of intra-abdominal pressure after abdominal surgery, according to the surgical incision in the abdomen (superior or inferior.METHODS:We prospectively evaluated 60 patients who underwent elective open abdominal surgery with a surgical time greater than 240 minutes. Patients were evaluated before surgery and on the 3rd postoperative day. Spirometry was assessed by maximal respiratory maneuvers and flow-volume curves. Intra-abdominal pressure was measured in the postoperative period using the bladder technique.RESULTS:The mean age of the patients was 56±13 years, and 41.6% 25 were female; 50 patients (83.3% had malignant disease. The patients were divided into two groups according to the surgical incision (superior or inferior. The lung volumes in the preoperative period showed no abnormalities. After surgery, there was a significant reduction in both FEV1 (1.6±0.6 L and FVC (2.0±0.7 L with maintenance of FEV1/FVC of 0.8±0.2 in both groups. The maximum intra-abdominal pressure values were similar (p= 0.59 for the two groups. There was no association between pulmonary volumes and intra-abdominal pressure measured in any of the groups analyzed.CONCLUSIONS:Our results show that superior and inferior abdominal surgery determines hypoventilation, unrelated to increased intra-abdominal pressure. Patients at high risk of pulmonary complications should receive respiratory care even if undergoing inferior abdominal surgery.

    The plain abdominal x-ray is still the first imaging modality in diagnosis of acute abdomen. The aim of this study was to find the value of plain abdominal x-ray in the management of abdominal emergencies seen in Lagos university teaching hospital. The accurate diagnosis of the cause of acute abdominal pain is one of the most challenging undertakings in emergency medicine. This is due to overlapping of clinical presentation and non-specific findings of physical and even laboratory data of the multifarious causes. Plain abdominal radiography is one investigation that can be obtained readily and within a short period of time to help the physician arrive at a correct diagnosis The relevance of plain abdominal radiography was therefore evaluated in the management of abdominal emergencies seen in Lagos over a 12 month period (April 2002 to March 2003). A prospective study of 100 consecutively presenting patients with acute abdominal conditions treated by the general surgical unit of Lagos University Teaching Hospital was undertaken. All patients had supine and erect abdominal x-ray before any therapeutic intervention was undertaken. The diagnostic features of the plain films were compared with final diagnosis to determine the usefulness of the plain x-ray There were 54 males and 46 females (M:F 1.2:1). Twenty-four percent of the patients had intestinal obstruction, 20% perforated typhoid enteritis; gunshot injuries and generalized peritonitis each occurred in 13%, blunt abdominal trauma in 12%, while 8% and 10% had acute appendicitis and perforated peptic ulcer disease respectively. Of 100 patients studied, 54% had plain abdominal radiographs that showed positive diagnostic features. Plain abdominal radiograph showed high sensitivity in patients with intestinal obstruction 100% and perforated peptic ulcer 90% but was less sensitive in patients with perforated typhoid, acute appendicitis, and blunt abdominal trauma and generalized peritonitis.

  15. Mechanisms and management of functional abdominal pain.

    Functional abdominal pain syndrome is characterised by frequent or continuous abdominal pain associated with a degree of loss of daily activity. It has a reported population prevalence of between 0.5% and 1.7%, with a female preponderance. The pathophysiology of functional abdominal pain is incompletely understood although it has been postulated that peripheral sensitisation of visceral afferents, central sensitisation of the spinal dorsal horn and aberrancies within descending modulatory systems may have an important role. The management of patients with functional abdominal pain requires a tailored multidisciplinary approach in a supportive and empathetic environment in order to develop an effective therapeutic relationship. Patient education directed towards an explanation of the pathophysiology of functional abdominal pain is in our opinion a prerequisite step and provides the rationale for the introduction of interventions. Interventions can usefully be categorised into general measures, pharmacotherapy, psychological interventions and 'step-up' treatments. Pharmacotherapeutic/step-up options include tricyclic antidepressants, serotonin noradrenergic reuptake inhibitors and the gabapentinoids. Psychological treatments include cognitive behavioural therapy and hypnotherapy. However, the objective evidence base for these interventions is largely derived from other chronic pain syndrome, and further research is warranted in adult patients with functional abdominal pain. © The Royal Society of Medicine.

    To study the clinical presentation and outcome of cases of Abdominal Tuberculosis. Fifty four patients of Abdominal Tuberculosis were seen during the study period. Four patients were lost to follow-up, which were excluded. Detailed information of all the patients including age, sex, symptoms, signs, investigations and management was recorded, analyzed and compared with local and international data. Out of the 50 patients with Abdominal Tuberculosis, 31 were females and 19 males. Their ages ranged from 17 to 63 years, with a mean age of 25.1 years. Thirty five cases were admitted through Emergency and 15 through Outpatients departments. Abdominal pain was the most common symptom found in 44 (88%) patients followed by vomiting in 33 (66%). Abdominal tenderness was seen in 22 (44%) patients, while 16 (32%) patients had rigidity and other features of peritonitis. Surgery was performed in all these patients, limited right hemicolectomy in 17 (34%), segmental resection and anastomosis in 12 (24%), ileostomy and strictureplasty in six (12%) each, repair of perforation in five (10%) and adhesiolysis in four (8%) patients. Overall mortality was 8% due to septicaemia and multiorgan failure. Abdominal Tuberculosis is a significant clinical entity with lethal complications in neglected cases. It affects a younger age group and is more common in females. Clinical features are rather non-specific but vague ill health, low grade fever, weight loss and anorexia may help to diagnose the case.

  17. Abdominal MR: liver and pancreas

    International Nuclear Information System (INIS)

    1999-01-01

    Following the introduction of rapid, high-quality scan techniques and the development of new, tissue-specific contrast agents, the applications of MRI for abdominal imaging are experiencing unprecedented growth. This article examines the current status of liver and pancreatic MRI, highlighting technical and methodological approach, use of contrast agents, and main clinical applications. The MRI technique appears to be the ideal diagnostic tool for detection and characterization of benign and malignant liver neoplasms, and for evaluating tumor response after nonsurgical treatments. Dynamic imaging after bolus injection of a gadolinium chelate is currently a fundamental component of an MRI examination of the liver in many instances. Optimal dynamic scanning depends on the use of a multisection spoiled gradient-echo technique that allows one to image the entire region of interest during a single suspended respiration. Images are obtained during four phases relative to the injection of the contrast agent: precontrast, arterial (pre-sinusoidal), portal (sinusoidal), and delayed (extracellular) phase. Liver-specific contrast agents, including hepatobiliary agents and reticuloendothelial system-targeted iron oxide particles, however, may offer advantages over gadolinium chelates in some clinical settings. Computed tomography is still preferred to MRI for imaging the pancreas. However, state-of-the-art MRI may currently be at least as accurate as spiral CT for depiction of inflammatory and neoplastic pancreatic diseases. Moreover, MRI has the advantage of allowing simultaneous investigation of the biliary tree, owing to cholangiopancreatography techniques. Hence, a comprehensive assessment of most pancreatic diseases can be achieved with a single examination. (orig.)

  18. Image mottle in abdominal CT.

    1999-04-01

    To investigate image mottle in conventional CT images of the abdomen as a function of radiographic technique factors and patient size. Water-filled phantoms simulating the abdomens of adult (32 cm in diameter) and pediatric (16 cm in diameter) patients were used to investigate image mottle in CT as a function of x-ray tube potential and mAs. CT images from 39 consecutive patients with noncontrast liver scans and 49 patients with iodine contrast scans were analyzed retrospectively. Measurements were made of the mean liver parenchyma Hounsfield unit value and the corresponding image mottle. For a given water phantom and x-ray tube potential, image mottle was proportional to the mAs-0.5. Increasing the phantom diameter from 16 cm (pediatric) to 32 cm increased the mottle by a factor of 2.4, and increasing the x-ray tube potential from 80 kVp to 140 kVp reduced the mottle by a factor of 2.5. All patients were scanned at 120 kVp, with no correlation between patient size and the x-ray tube mAs. The mean mottle level was 7.8 +/- 2.2 and 10.0 +/- 2.5 for the noncontrast and contrast studies, respectively. An increase in patient diameter of 3 cm would require approximately 65% more mAs to maintain the same level of image mottle. The mottle in abdominal CT images may be controlled by adjusting radiographic technique factors, which should be adjusted to take into account the size of the patient undergoing the examination.

    To determine the accuracy of complaints of abdominal pain and findings of abdominal tenderness for identifying children with intra-abdominal injury (IAI) stratified by Glasgow Coma Scale (GCS) score. This was a prospective, multicenter observational study of children with blunt torso trauma and a GCS score ≥13. We calculated the sensitivity of abdominal findings for IAI with 95% CI stratified by GCS score. We examined the association of isolated abdominal pain or tenderness with IAI and that undergoing acute intervention (therapeutic laparotomy, angiographic embolization, blood transfusion, or ≥2 nights of intravenous fluid therapy). Among the 12 044 patients evaluated, 11 277 (94%) had a GCS score of ≥13 and were included in this analysis. Sensitivity of abdominal pain for IAI was 79% (95% CI, 76%-83%) for patients with a GCS score of 15, 51% (95% CI, 37%-65%) for patients with a GCS score of 14, and 32% (95% CI, 14%-55%) for patients with a GCS score of 13. Sensitivity of abdominal tenderness for IAI also decreased with decreasing GCS score: 79% (95% CI, 75%-82%) for a GCS score of 15, 57% (95% CI, 42%-70%) for a GCS score of 14, and 37% (95% CI, 19%-58%) for a GCS score of 13. Among patients with isolated abdominal pain and/or tenderness, the rate of IAI was 8% (95% CI, 6%-9%) and the rate of IAI undergoing acute intervention was 1% (95% CI, 1%-2%). The sensitivity of abdominal findings for IAI decreases as GCS score decreases. Although abdominal computed tomography is not mandatory, the risk of IAI is sufficiently high that diagnostic evaluation is warranted in children with isolated abdominal pain or tenderness.

En estos casos, se requiere de una conexión directa con el cerebro del paciente para detectar una respuesta. Por consiguiente, en este artículo se desarrolla y analiza un modelo computacional basado en los principios de las máquinas de soporte vectorial (MSV, para inferir el estado cognitivo de pacientes en estados derivados del coma, mediante la utilización de un equipo de electroencefalografía comercial. Los resultados obtenidos, mostraron que el modelo logró clasificar correctamente una tarea cognitiva en al menos cuatro de cada cinco pruebas en pacientes de control, lo que se traduce en la obtención de un sistema de bajo costo para el análisis del estado de conciencia y para la posible comunicación con algunos pacientes en estados derivados del coma mediante protocolos médicos definidos. De esta manera, este sistema se presenta como un gran aporte para las clínicas y centros hospitalarios, como herramienta potencial de diagnóstico para este tipo de pacientes.

    The low FODMAP diet (fermentable oligosaccharides, monosaccharides, disaccharides, and polyols) has shown to be effective in adult patients with irritable bowel syndrome, but there are few studies on paediatric patients. The aim of this study is to assess the implementation and the outcomes of a low FODMAP diet in the treatment of functional abdominal pain in children from a Mediterranean area. A table was designed in which foods were classified according to their FODMAP content, as well as a 'Symptoms and Stools Diary'. A prospective study was conducted on children with functional abdominal pain in our Paediatric Gastroenterology Unit. A total of 22 patients were enrolled in the trial, and 20 completed it. Data were collected of the abdominal pain features over a period of 3 days, and then patients followed a two-week low FODMAP diet. Afterwards, information about abdominal pain features was collected again. After the diet, they showed fewer daily abdominal pain episodes compared to baseline (1.16 [IQR: 0.41-3.33] versus 2 [IQR: 1.33-6.33] daily episodes, P=.024), less pain severity compared to baseline (1.41cm [IQR: 0.32-5.23] versus 4.63cm [IQR: 2.51-6.39] measured by 10-cm Visual Analogue Scale, P=.035), less interference with daily activities, and less gastrointestinal symptoms. Only 15% of patients found it difficult to follow the diet. The implementation of a low FODMAP diet for 2 weeks in a Mediterranean paediatric population diagnosed with functional abdominal pain is possible with adapted diets. It was highly valued by patients, and they showed an improvement in abdominal pain symptoms assessed by objective methods. Copyright © 2018. Publicado por Elsevier España, S.L.U.

    2017-02-01

    To summarize the association of vitamins (B6, B12, C, D, and E) and abdominal aortic aneurysm (AAA), we reviewed clinical studies with a comprehensive literature research and meta-analytic estimates. To identify all clinical studies evaluating the association of vitamins B6/B12/C/D/E and AAA, databases including MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched through April 2015, using Web-based search engines (PubMed and OVID). For each case-control study, data regarding vitamin levels in both the AAA and control groups were used to generate standardized mean differences (SMDs) and 95% confidence intervals (CIs). Pooled analyses of the 4 case-control studies demonstrated significantly lower circulating vitamin B6 levels (SMD, -0.33; 95% CI, -0.55 to -0.11; P=0.003) but non-significantly lower vitamin B12 levels (SMD, -0.42; 95% CI, -1.09 to 0.25; P=0.22) in patients with AAA than subjects without AAA. Pooled analyses of the 2 case-control studies demonstrated significantly lower levels of circulating vitamins C (SMD, -0.71; 95% CI, -1.23 to -0.19; P=0.007) and E (SMD, -1.76; 95% CI, -2.93 to 0.60; P=0.003) in patients with AAA than subjects without AAA. Another pooled analysis of the 3 case-control studies demonstrated significantly lower circulating vitamin D (25-hydroxyvitamin D) levels (SMD, -0.25; 95% CI, -0.50 to -0.01; P=0.04) in patients with AAA than subjects without AAA. In a double-blind controlled trial, 4.0-year treatment with a high-dose folic acid and vitamin B6/B12 multivitamin in kidney transplant recipients did not reduce a rate of AAA repair despite significant reduction in homocysteine level. In another randomized, double-blind, placebo-controlled trial, 5.8-year supplementation with α-tocopherol (vitamin E) had no preventive effect on large AAA among male smokers. In clinical setting, although low circulating vitamins B6/C/D/E (not B12) levels are associated with AAA presence, vitamins B6/B12/E

El estudio postmortem descubrió dos masas de 3-4 cm de diámetro en el ileon distal que, al microscopio, correspondieron a inflamación severa de toda la pared intestinal, rica en eosinofilos y en granulomas con células gigantes que circunscribian y fagocitaban huevos y larvas de Angiostrongylus costaricensis, helminto situado también dentro de las arterias de la submucosa, vasos que presentaban engrosamiento de la intima y focos con inflamación granulomatosa con eosinófilos. La niña no presentó leucocitosis ni eosinofilia. Este es el segundo caso de angiostrongilosis de esta región. El primero fue el de una mujer indigena de 34 años también con hematoquecia anemizante. La angiostrongilosis abdominal se diagnosticó por primera vez en Colombia en 1979, en un niño de 5 años, de Dagua, Valle. La niña aquí presentada es el sexto paciente con esta entidad en Colombia. La hematoquecia como manifestación predominante de la angiostrongilosis es extraordinaria para una enfermedad parasitaria; se ha registrado solamente en tres ocasiones anteriores. La abundancia de cristales de Charcot-Leyden, que se tiñen muy bien con la coloración de Ziehl-Neelsen o de Fite-Faraco, en los infiltrados de la pared intestinal. sugiere que su búsqueda en las heces puede ser una ayuda en el diagnóstico de casos sospechosos. pues, los huevos y las larvas no se eliminan en las heces y el diagnóstico definitivo de la angiostrongilosis es histopatológico. Revisamos las caracteristicas clinicas, parasitológicas e histopatológicas de esta parasitosis que será más prevalente en Colombia a medida que los médicos. especialmente los patólogos, la conozcan mejor.

    AIM: The technical performance of abdominal ultrasound in the investigation of acute abdominal pain has been thoroughly investigated but its therapeutic effects are less well understood. We aimed to determine the therapeutic effect of abdominal ultrasound in the investigation of acute abdominal pain. MATERIAL AND METHODS: A pre- and post-intervention observational study design was used to determine the diagnostic and therapeutic effects of abdominal ultrasound for acute abdominal pain. Referring clinicians completed a pre-ultrasound questionnaire that detailed their leading diagnosis, confidence in this and intended management in 100 consecutive adult patients. Following ultrasound a second questionnaire was completed. This again detailed the leading diagnosis, confidence in this and their intended management. Clinicians quantified the management contribution of ultrasound both for the individual case in question and in their clinical experience generally. RESULTS: The leading diagnosis was either confirmed or rejected in 72 patients and a new diagnosis provided where no prior differential diagnosis existed in 10. Diagnostic confidence increased significantly following ultrasound (mean score 6·5 pre-ultrasound vs 7·6 post-ultrasound, P < 0·001). Intended management changed following ultrasound in 22 patients; 15 intended laparotomies were halted and a further seven patients underwent surgery where this was not originally intended. Ultrasound was rated either 'very' or 'moderately' helpful in 87% of patients, with 99% of clinicians finding it either 'very' or 'moderately' helpful generally. CONCLUSION: Abdominal ultrasound has considerable diagnostic and therapeutic effect in the setting of acute abdominal pain. Dhillon, S. et al. (2002)

    INTRODUCTION: Evidence for the effect of post-operative abdominal binders on post-operative pain, seroma formation, physical function, pulmonary function and increased intra-abdominal pressure among patients after surgery remains largely un-investigated. METHODS: A systematic review was conducted...... formation and physical function. RESULTS: A total of 50 publications were identified; 42 publications were excluded leaving eight publications counting a total of 578 patients for analysis. Generally, the scientific quality of the studies was poor. Use of abdominal binder revealed a non-significant tendency...... to reduce seroma formation after laparoscopic ventral herniotomy and a non-significant reduction in pain. Physical function was improved, whereas evidence supports a beneficial effect on psychological distress after open abdominal surgery.

    Objective: To optimize the abdominal helical CT scanning parameters in pediatric patients and to reduce its radiation hazards. Methods: 60 canines were evenly grouped into 4 groups on the basis of pediatric abdominal perimeter, scanned with 110,150,190 and 240 mAs, and their qualities of canine CT images were analyzed. 120 pediafric patients with clinic suspected abdominal diseases were divided into 4 groups on the basis of abdominal perimeter, scanned by optimal parameters and their image qualities were analyzed. Results: After CT exposure were reduced, the percentages of total A and B were 90.9 % and 92.0 % in experimental canines and in pediatric patients, respectively. Compared with conventional CT scanning, the exposure and single slice CT dose index weighted (CTDIw) were reduced to 45.8%-79.17%. Conclusion: By adjusted the pediatric helical CT parameters basedon the of pediatric abdominal perimeter, exposure of patient to the hazards of radiation is reduced. (authors)

    There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 2012. Twenty articles were identified, in that, 12 literature reviews, 4 descriptive and exploratory studies, 2 expert opinions, one prospective cohort study and one was an experience report. The vesical intra-abdominal pressure measurement was considered gold standard. There are variations in the technique however, but some common points were identified: complete supine position, in absence of abdominal contracture, in the end of expiration and expressed in mmHg. Most research results indicate keeping the transducer zeroed at the level of the mid-axillary line at the iliac crest level, and instill 25mL of sterile saline. Strong evidence must be developed. RESUMO Em pacientes críticos com quadros abdominais agudos a esclarecer é crescente a solicitação da aferição da pressão intra-abdominal.

    Full Text Available BACKGROUND Blunt abdominal trauma is an emergency and is associated with significant morbidity and mortality. The aim of the study is to study incidence, demographic profile, epidemiological factors, mechanism of trauma, treatment modalities, associated injuries, postoperative complications and morbidity and mortality. MATERIALS AND METHODS A retrospective analysis of 72 patients of blunt abdominal trauma who were admitted in government general hospital between May 2013 to April 2015 in Department of General Surgery, Government General Hospital, Guntur, with in a span of 24 months were studied. Demographic data, mechanism of trauma, management and outcome were studied. RESULTS Most of the patients in our study were in the age group of 21-30 years. Spleen was the commonest organ involved and most common procedure performed was splenectomy. Most common extra-abdominal injury was rib fractures. Wound infection was the commonest complication. CONCLUSION Initial resuscitative measures, thorough clinical examination and correct diagnosis forms the vital part of the management. FAST is more useful in blunt abdominal trauma patients who are unstable. X-ray revealed 100% accuracy in hollow viscous perforation in blunt abdominal trauma patients. CT abdomen is more useful in stable patients. Definitive indication for laparotomy was haemodynamic instability and peritonitis. Associated injuries influenced morbidity and mortality. Early diagnosis and prompt treatment can save many lives.

    Full Text Available Cystic fibrosis (CF is a multisystem disease with a range of abdominal manifestations including those involving the liver, pancreas, and kidneys. Recent advances in management of the respiratory complications of the disease has led to a greater life expectancy in patients with CF. Subsequently, there is increasing focus on the impact of abdominal disease on quality of life and survival. Liver cirrhosis is the most important extrapulmonary cause of death in CF, yet significant challenges remain in the diagnosis of CF related liver disease. The capacity to predict those patients at risk of developing cirrhosis remains a significant challenge. We review representative abdominal imaging findings in patients with CF selected from the records of two academic health centres, with a view to increasing familiarity with the abdominal manifestations of the disease. We review their presentation and expected imaging findings, with a focus on the challenges facing diagnosis of the hepatic manifestations of the disease. An increased familiarity with these abdominal manifestations will facilitate timely diagnosis and management, which is paramount to further improving outcomes for patients with cystic fibrosis.

    The present study aimed to determine the intra-abdominal pressure during front crawl swimming at different velocities in competitive swimmers and to clarify the relationships between stroke indices and changes in intra-abdominal pressure. The subjects were 7 highly trained competitive collegiate male swimmers. Intra-abdominal pressure was measured during front crawl swimming at 1.0, 1.2 and 1.4 m · s(-1) and during the Valsalva maneuver. Intra-abdominal pressure was taken as the difference between minimum and maximum values, and the mean of 6 stable front crawl stroke cycles was used. Stroke rate and stroke length were also measured as stroke indices. There were significant differences in stroke rate among all velocities (P pressure and stroke rate or stroke length (P pressure and stroke indices when controlling for swimming velocity. These findings do not appear to support the effectiveness of trunk training performed by competitive swimmers aimed at increasing intra-abdominal pressure. © Georg Thieme Verlag KG Stuttgart · New York.

    Li Shao

    Full Text Available BACKGROUND: Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS: Patients (n = 160 scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients' nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. RESULTS: When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. DISCUSSION: The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed.

    Twenty six patients were studied with 67 Gallium to detect and localize the site of intra-abdominal and intraperitoneal infection. They were divided in two groups: a) with and b) without physical symptoms that could localize an abcess in the abdominal cavity. All the patients with suppuration had persistent up-take of 67 Ga in one anatomic area of the abdomen, subsequently documented by computarized axial tomography (CAT) in 58% of the cases or by laparotomy in 88% of them. Scintigraphy with 67 Ga in the patients with recent surgery not only detected focal infection in 67% of the cases but excluded subphernic collection. In 78% of patients with prolonged fever, the infection was localized. There was no false positive result. The comparison in 56% of the cases with CAT demonstrated that both techniques are 100% sensitive for the diagnosis of abdominal suppurative processes. Three of the 26 patients, after six weeks of medical treatment, were restudied with 67 Ga and CAT, showing total resolution of their previous abnormalities. It is concluded that 67 Ga scintigraphy performed as the first study in febrile patients independent of the presence or absence of physical symptoms that could localize the abdominal infection, is sensitive for the detection and localization of an abdominal abscess and that a negative result excludes it.

    Objective: To discuss the value of CT in diagnosis of abdominal ectopic pheochromocytoma. Methods: CT findings of 5 cases surgically and pathologically proved with ectopic pheochromocytoma were retrospectively analyzed. Results: Soft tissue mass with light asymmetry enhancement was found between the abdominal aorta and the inferior vena ca-va in one case. 1 case was completely cystic with light enhancement of the cystwall located in front of the left side of the abdominal aorta. 1 case of large solid mass occurred between the renal hilum and the tail of pancreas, with irregular shape, unclear boundary, central necrosis, calcification and obviously enhancement at the solid part. 2 cases showed as oval soft lump with even density, moderate strengthening located before the abdominal aorta. Paroxysmal hypertension occurred in 3 cases and didn't in 2 cases. Hypertension happened in 1 case during the operation because of stimulation. Blood pressure appeared in 1 case during and after operation. Blood and urinary catecholamine increased significantly in 4 cases. Conclusion: Ectopic pheochromocytoma mainly located surround the abdominal aorta with diverse CT performance. It is helpful for diagnosing when finding a lesion locates at the specified sites combined with typical clinical presentation. CT can not only depict small tumor, but also can show the relationship with surrounding structure, and it provides important information for the operation and prognosis. (authors)

    Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

  13. La Defensa, Política de Estado

    2008-12-01

    Full Text Available The areas of the State Policy are set, specially focussing on the Defense as it is closely related to concepts like National Interest and Anglo-Saxon bipartisan policy. Nevertheless, the political alternation will cause differences. It is also necessary to tell the difference between the State Policy and the Policy carried out by the State. That’s why the democratic Parliaments play a fundamental role in shaping the defence policy. Although the Parliament symbolizes the National Sovereignty there can be and there are actually differences with the Public Opinion. This sort of divorce is not really new as, in Spain, it became evident in a very intensive way on the occasion of decisions such as the Spanish entry into the NATO. A State Policy related to Defense, kept during a long time and resistant to political alternation would certainly be the best instrument to reach a culture of defense.Se establecen los ámbitos de las políticas de estado, con especial énfasis en la Defensa al estar esta vinculada al concepto de interés nacional, y al anglosajón bipartisan policy. No obstante, la alternancia política va a crear discrepancias. Conviene diferenciar la “Política de Estado” y la “Política del Estado”. Por ello, los Parlamentos democráticos juegan un papel fundamental en la conformación de la política de defensa. Pese a que el Parlamento representa a la soberanía nacional pueden producirse, y de hecho se producen, discrepancias con la opinión pública. Este divorcio no es nuevo y en España se ha manifestado de forma muy intensa con ocasión de tomas de decisión como la incorporación a la OTAN. Una política de Estado en defensa, mantenida en el tiempo y resistente a las alternancias políticas sería el instrumento más adecuado para lograr una cultura de defensa.

    Full Text Available RESUMEN: El concepto de “intelectual” es difícil de definir y sin duda se debate constantemente. Sin embargo, es importante reflexionar sobre él a fin de comprender su significado y los problemas que implica. Sea como fuere, a un Estado autoritario “moderno” se le supone una única ideología que tiene que difundirse por medio de una propaganda bien organizada, proceso en el que los intelectuales desempeñan un papel significativo. El “Nuevo Estado” de Salazar encaja en esta categoría y sin duda el conocimiento acerca de sus “intelectuales” es fundamental. En este artículo, el objetivo es proporcionar algunos ejemplos interesantes de “intelectuales” o de simples “funcionarios políticos” con inclinación intelectual a fin de indicar el sentido y complejidad de un estudio con una dimensión distinta sobre este asunto. A este fin han sido seleccionadas tres personalidades responsables de la actividad ideológica y cultural de gran relieve en el Estado de Salazar: António Ferro, João Ameal y Costa Brochado. Palabras clave: Estado Novo; Authotitarianism; Salazar, António de Oliveira; Intellectuals; Ferro, António; Brochado, Idalino da Costa; Ameal, João. ABSTRACT: The concept of the “intellectual” is difficult to define and undoubtedly constantly debated. It is nevertheless important to reflect on it in order to understand its meaning and the problems involved with it. Be that as it may, a “modern” authoritarian State presumes a single ideology which has to be diffused by means of well-organised propaganda, in which process “intellectuals” play a significant role. Salazar’s “New State” fits this category and, undoubtedly, knowledge about its “intellectuals” is fundamental. The objective in this article is to provide some interesting examples of “intellectuals” or simple “political functionar- ies” with an intellectual bent so as to indicate the sense and complexity of a study of a

    Full Text Available La convulsión financiera iniciada en octubre de 2008 ha reavivado el debate político, social y doctrinal sobre las debilidades del sistema monetario y financiero internacional. Desde su consolidación institucional en la segunda post-guerra mundial, su legitimidad,eficiencia y justicia se han cuestionado constantemente. En estos últimos meses, su incapacidad para prever y evitar crisis como la actual se ha criticado especialmente. La crisis de la deuda de los años ochenta, el “tequilazo” mexicano de 1994 o la crisisasiática de finales de los años noventa ponen de manifiesto la existencia de elementos que dichas instituciones no han sido capaces de controlar. La cadena de infortunios financieros de los últimos meses lo corrobora y hace necesaria una profunda reflexión en términos económicos, jurídicos y también institucionales.El Fondo Monetario Internacional constituye, junto con el Banco Internacional de Reconstrucción y Fomento, el núcleo del sistema monetario y financiero internacional. Creado por los acuerdos de Bretton Woods en diciembre de 1945, el Fondo debía encargarse en su origen de favorecer la estabilidad financiera y el crecimiento económico de los Estados, poniendo a disposición de éstos sus recursos. Con el paso de los años, su cometido se ha ampliado abarcando cada vez más aspectos como la supervisión de las políticas económicas de los países miembros o la influencia en las políticas macroeconómicas nacionales. Esa extensión de sus facultades va unida, sin lugar a duda, a una creciente responsabilidad por el cumplimiento satisfactorio de su misión.Teniendo esto en cuenta, el actual debate sobre la necesidad de una nueva arquitectura financiera internacional debe ahondar en las fortalezas y debilidades del Fondo, por su papel fundamental en la misma. En este sentido, la reforma iniciada en 2005 bajo ladirección del español Rodrigo Rato se ha enfrentado a la evaluación más exigente: una crisis

    Full Text Available Gossypiboma is a mass lesion at the site of surgery due to a forgotten surgical sponge. Forgotten foreign bodies are mostly retained in the abdominal cavity but there are some cases in the thorax, cranium, breast, and an extremity. Gossypiboma should be considered, especially by radiologists, in patients with a history of surgery, who present with non-specific symptoms and abdominal mass. In this report, we describe the case of a female patient who presented with non-specific abdominal discomfort and fever about six months after open cholecystectomy.

    Full Text Available Abdominal aorta wounds carries a high immediate mortality. Few patients reach hospital care alive. There are no reports on Medline (1969-2002 about aortic wounds of foreign body with retention. A case with upper abdominal aortic wound with an inlaid blade is reported. The retained blade fixed the stomach to the surgical field, difficulting the vascular control, leading to an unconventional approach and allowing extensive contamination. The patient developed multiple organ dysfunction and died at fifth postoperative day. Singularities of an inlaid knife in upper abdominal aorta and changes in traditional approach are discussed. The authors assumed that the inlaid knife decreased the bleeding, allowing the patient arrival to the hospital, but worsened the approach to the aorta wound.

    Full Text Available Coarctation of the abdominal aorta is an extremely rare vascular defect inwhich congenital or acquired etiologies have been described. This case concernsa 30-year-old pregnant woman with 15-years history of uncontrolled hypertensionand lower limb claudication presented with worsened hypertension during herfirst pregnancy. Magnetic resonance angiography study of aorta revealed astenosis in abdominal aorta about 12mm from the origin of celiac axisaccompanied by left sided aortic arch and right aberrant subclavian artery. Thiscase highlights the importance of a throughout physical examination in patientspresented with hypertension and it emphasizes considering the coarctation of theabdominal aorta during the diagnostic workup of hypertension, especially inyoung patients. In such cases magnetic resonance angiography of the aorta is auseful tool to reach a definitive diagnosis especially in pregnant women.Also to our knowledge, this patient is the first one found to have aortic archmalformation combined with an abdominal coarctation.

    Intra-abdominal cryptococcosis was diagnosed in two young dogs. The first, an entire male border collie, was presented with vomiting. An abdominal mass detected during physical examination proved to be cryptococcal mesenteric lymphadenitis on exploratory laparotomy. The second dog, a female neutered giant schnauzer, was presented with neurological signs suggestive of encephalopathy. Intestinal cryptococcal granulomas were detected in an extensive diagnostic investigation which included abdominal ultrasonography. The gastrointestinal tract was considered the most likely portal of entry for cryptococcal organisms in both cases. Both dogs were treated using surgery and multiagent antifungal chemotherapy. The first case succumbed despite therapy, while the second dog was treated successfully as gauged by return to clinical normality and a substantial decline in the cryptococcal antigen titre which continued to fall after cessation of treatment.

    The prognosis of ovarian cancers, which are frequently diagnosed at a late stage, can probably be improved by whole abdominal radiotherapy. 45 patients in Lyon and 8 patients in Montelimar (7 stage I or C, 10 stage II and 36 stage III) were treated by whole abdominal radiotherapy, generally after 6 courses of chemotherapy (46 cases). The overall 5-year survival of this group of patients was 48% (Kaplan-Meier method). When the patients treated by complete resection at 1st look surgery (19 cases) are compared with those in whom 1st look surgery was incomplete (34 cases), the actuarial survival was 83% versus 27%. This study demonstrates that whole abdominal radiotherapy is feasible without any serious long-term complications after two operations and 6 courses of chemotherapy. These encouraging results need to be confirmed by randomized prospective studies [fr

    Computed tomography is an accurate method of identifying the various types of abdominal wall hernias, especially if they are clinically occult, and of distinguishing them from other diseases such as hematomas, abscesses and neoplasia. In this study we examined the CT images of 94 patients affected by abdominal wall hernias observed over a period of 6 years. Computed tomography clearly demonstrates the anatomical site of the hernial sac, the content and any occlusive bowel complications due to incarceration or strangulation. Clinical diagnosis of external hernias is particularly difficult in obese patients or in those with laparotic scars. In these cases abdominal imaging is essential for a correct preoperative diagnosis and to determine the most effective treatment. (orig.)

    To identify the association of dietary, socioeconomic factors, sedentary behaviors and maternal nutritional status with abdominal obesity in children. A cross-sectional study with household-based survey, in 36 randomly selected census tracts in the city of Santos/SP. 357 families were interviewed and questionnaires and anthropometric measurements were applied in mothers and their 3-0 years-old children. Assessment of abdominal obesity was made by maternal and child's waist circumference measurement; for classification used cut-off points proposed by World Health Organization (1998) and Taylor et al. (2000) were applied. The association between variables was performed by multiple logistic regression analysis. 30.5% of children had abdominal obesity. Associations with children's and maternal nutritional status and high socioeconomic status were shown in the univariate analysis. In the regression model, children's body mass index for age (OR=93.7; 95%CI 39.3-223.3), female gender (OR=4.1; 95%CI 1.8-9.3) and maternal abdominal obesity (OR=2.7; 95%CI 1.2-6.0) were significantly associated with children's abdominal obesity, regardless of the socioeconomic status. Abdominal obesity in children seems to be associated with maternal nutritional status, other indicators of their own nutritional status and female gender. Intervention programs for control of childhood obesity and prevention of metabolic syndrome should consider the interaction of the nutritional status of mothers and their children.

    The abdominal sacrocolpopexy is an excellent procedure to surgically treat vaginal vault prolapse. A synthetic graft is often used to support the vaginal apex, but has the potential to become infected or erode, requiring its removal or revision. The purpose of this paper is to report our experience in the management of patients with infected synthetic grafts after abdominal sacrocolpopexy. A review of the patient databases from three specialty gynecology centers was performed from March 1996 to June 2002. Only patients with an infected graft after an abdominal sacrocolpopexy were included in the study; patients with either suture or graft erosion responding to conservative treatment were excluded. Twenty-two women, ages 37-73 years, developed infection of the synthetic graft after an abdominal sacrocolpopexy (1-60 months after their initial surgery, mean 8.8 months). The infected materials included polytetrafluoroethylene (PTFE, Goretex, n =15) and polypropylene (n=7). Nine of the 15 PTFE meshes and four of the seven polypropylene meshes were placed at the time of a contaminated case (abdominal hysterectomy [n=12], colon resection [n=1]). Eighteen (82%) of the infected grafts involved braided permanent suture to attach the graft to the vaginal wall, monofilament/non-braided permanent suture was used in three patients, and suture type could not be determined in one. All graft removals were attempted vaginally, and this was successful in 16 cases (73%). Two patients experienced significant bleeding: the first patient required an emergency laparotomy and the second patient's bleeding was controlled with packing. A rectovaginal fistula occurred 3 weeks postoperatively in one patient. Synthetic graft infection should be considered as the differential diagnosis in a patient who has undergone an abdominal sacrocolpopexy. Transvaginal removal is preferred, but is fraught with potentially serious complications. The use of braided permanent sutures to affix the graft to the

    Abdominal compartment syndrome is a systemic syndrome involving derangement in cardiovascular hemodynamics, respiratory and renal function as a result of sustained increase in intra-abdominal pressure. This results in multi-organ failure requiring prompt action and treatment. Presentation can be acute, chronic and acute on chronic. Initial diagnosis is clinical, confirmed by measurement of urinary bladder pressure. Treatment is abdominal decompression by laparostomy and delayed abdominal closure. Awareness among the surgeons has increased because laparoscopy has resulted in determination of intra-abdominal pressure as a readily measurable quantity. They have been able to appreciate the benefit of abdominal decompression by performing repeated planned laparotomies for trauma. (author)

    Radioecological monitoring issues and radiation safety are actual in the Republic of Moldova. Japan events show us the possibility of natural disasters. Republic of Moldova is surrounded by 8 NPPs, the closest being at the distance of 160 km. Moldovas territory is in seismic zone where underground earthquake shocks reaches 7 points or more. Thatis why radiation safety and radioecological monitoring is actual in our republic. Traces of Chernobyl were left in Moldovas soils. The fallouts of radio nuclides formed on the soil surfaces in the Republic of Moldova following the Chernobyl Nuclear Power Station Accident have been continuously affected by attacks of both natural and technicaly generated agents since the time of fallout. During the past decade a shift in emphasis has taken place regarding the need for more complete and accurate information on reservoir sedimentation. Classical sedimentation surveys involve repeated field measurement and, therefore, this is probably the most costly and time consuming method. The application of radio nuclides, particularly Cs 137, for water erosion and sedimentation studies in Republic of Moldova has not been attempted so far. This paper presents the results obtained on reservoir sedimentation rates in an area subjected to wide range in land degradation dy sheet-rill erosion. The profil characteristics support the assumption that in most undisturbed sites there is a sharp decline in Cs 137 activity with increasing dept. Such an asymmetrical distribution of the Cs 137 would suggest a standard pattern in the form of a cantilever. If the validity of this assamption is accepted it is possible to define two major types of Cs 137 cantilever distribution: shallow and deep buried cantilever. The main criterion in classifying these pattents lies generally in the shape of Cs 137 depth profile and particularly in burial magnitude of Cs 137 peak derived from Chernobyl. Hills area has been impacted by greatest sendimentation. This regional

    Systemic lupus erythematosus(SLE) is a systemic disease of unknown etiology. Its main pathology is vasculitis and serositis, due to deposition of the immune complex or antibodies. Most findings are nonspecific ; abdominal manifestations include enteritis, hepatomegaly, pancreatic enlargement, serositis, lymphadenopathy, splenomegaly, nephritis, interstitial cystitis, and thrombophlebitis. We described radiologic findings of various organ involvement of SLE; digestive system, serosa, reticuloendothelial system, urinary system, and venous system. Diagnosis of SLE was done according to the criteria of American Rheumatism Association. Understanding of the variable imaging findings in SLE may be helpful for the early detection of abdominal involvement and complications.

    Ovarian function was studied in 18 female patients treated for abdominal tumours during childhood. All received abdominal radiotherapy as part of their treatment and were studied between 1 and 26 years after irradiation. The serum gonadotrophins and oestradiol levels were consistent with ovarian failure in each case and there was a disproportionate elevation in serum follicle stimulating hormone (FSH) when compared to serum luteinizing hormone (LH) in 16. In 2 patients, the radiotherapeutic field extended downwards only as far as the sacral promontory. However, these 2 girls show similar evidence of ovarian failure to that in the other 16. (author)

The application of damage control surgery has significantly improved the clinical outcome of severe abdominal injury. With appropriate surgical intervention, post-trauma fluid resuscitation plays an increasingly important role in the treatment of abdominal injury. The damage control resuscitation strategy addresses the importance of permissive hypotension and haemostatic resuscitation for patients with severe trauma, under the guidance of damage control surgical principle.

    A 32-year-old Filipino female, working as an x-ray technician, presented to the Emergency Room (ER) with acute abdominal pain for one day. The pain was mainly on the left side and left hypochondrium. She had recurring abdominal pain before but not significant to worry her. She also complained of abdominal distension, which she noticed one week ago. Abdominal examination revealed fullness in the left hypochondrium with marked tenderness but negative rebound. Abdominal ultrasound (US) showed a huge mass mainly in the left hypochondrium. The origin of the mass cannot be identified by US. A computerized tomography scan showed a mass in the left side of the abdomen crossing the midline with a necrotic centre. The hospital course of the patient runs smoothly, and she was discharged after 7-days and referred to an Oncology Center. Abdominal mesothelioma is a neoplasm arising from the mesothelial surface lining the abdominal cavity. It is less frequent than that of the pleura. It is a rapidly growing and fatal malignancy with a median survival of less than 1-year. The relation between pleural malignant mesothelioma and asbestos is well recognized since it was described in 19602 but implication of asbestos exposure in the etiology of the peritoneal type is less obvious. This patient history is giving no obvious exposure to asbestos but as she is working in the Radiology Department as an x-ray technician she is well exposed to x-ray, but the effect of radioactivity on induction of mesothelioma is still disputed.4 There are several reports linking malignant mesothelioma to radioactivity due to radiation therapy.The fibrous mesothelioma (sarcomatous), as in this case, which is difficult to diagnose microscopically, looks like a fibroma, unless helped by tissue culture. The treatment options of malignant mesothelioma include surgery, intraperitoneal chemotherapy and whole abdominal radiation or multimodality therapy, which were suggested that might prolong the survival in

    This report presents the work that followed the CSSX model development completed in FY2002. The developed cesium and potassium extraction model was based on extraction data obtained from simple aqueous media. It was tested to ensure the validity of the prediction for the cesium extraction from actual waste. Compositions of the actual tank waste were obtained from the Savannah River Site personnel and were used to prepare defined simulants and to predict cesium distribution ratios using the model. It was therefore possible to compare the cesium distribution ratios obtained from the actual waste, the simulant, and the predicted values. It was determined that the predicted values agree with the measured values for the simulants. Predicted values also agreed, with three exceptions, with measured values for the tank wastes. Discrepancies were attributed in part to the uncertainty in the cation/anion balance in the actual waste composition, but likely more so to the uncertainty in the potassium concentration in the waste, given the demonstrated large competing effect of this metal on cesium extraction. It was demonstrated that the upper limit for the potassium concentration in the feed ought to not exceed 0.05 M in order to maintain suitable cesium distribution ratios

    2014-01-01

    Full Text Available Nanotechnologies are being spoken of as the driving force behind a new industrial revolution. Nanoscience has matured significantly during the last decade as it has transitioned from bench top science to applied technology. Presently, nanomaterials are used in a wide variety of commercial products such as electronic components, sports equipment, sun creams and biomedical applications. The size of nanoparticles allows them to interact strongly with biological structures, so they present potential human and environmental health risk. Nanometer size presents also a problem for separation, recovery, and reuse of the particulate matter. Therefore, industrial-scale manufacturing and use of nanomaterials could have strong impact on human health and the environment or the problematic of nanomaterials recycling. The catch-all term ''nanotechnology' is not sufficiently precise for risk governance and risk management purposes. The estimation of possible risks depends on a consideration of the life cycle of the material being produced, which involves understanding the processes and materials used in manufacture, the likely interactions between the product and individuals or the environment during its manufacture and useful life, and the methods used in its eventual disposal. From a risk-control point of view it will be necessary to systematically identify those critical issues, which should be looked at in more detail. Brief review of actual trends in nanomaterials environmental risks and recycling is given in this paper.

  9. Consequences of Predicted or Actual Asteroid Impacts

    Chapman, C. R.

    2003-12-01

    Earth impact by an asteroid could have enormous physical and environmental consequences. Impactors larger than 2 km diameter could be so destructive as to threaten civilization. Since such events greatly exceed any other natural or man-made catastrophe, much extrapolation is necessary just to understand environmental implications (e.g. sudden global cooling, tsunami magnitude, toxic effects). Responses of vital elements of the ecosystem (e.g. agriculture) and of human society to such an impact are conjectural. For instance, response to the Blackout of 2003 was restrained, but response to 9/11 terrorism was arguably exaggerated and dysfunctional; would society be fragile or robust in the face of global catastrophe? Even small impacts, or predictions of impacts (accurate or faulty), could generate disproportionate responses, especially if news media reports are hyped or inaccurate or if responsible entities (e.g. military organizations in regions of conflict) are inadequately aware of the phenomenology of small impacts. Asteroid impact is the one geophysical hazard of high potential consequence with which we, fortunately, have essentially no historical experience. It is thus important that decision makers familiarize themselves with the hazard and that society (perhaps using a formal procedure, like a National Academy of Sciences study) evaluate the priority of addressing the hazard by (a) further telescopic searches for dangerous but still-undiscovered asteroids and (b) development of mitigation strategies (including deflection of an oncoming asteroid and on- Earth civil defense). I exemplify these issues by discussing several representative cases that span the range of parameters. Many of the specific physical consequences of impact involve effects like those of other geophysical disasters (flood, fire, earthquake, etc.), but the psychological and sociological aspects of predicted and actual impacts are distinctive. Standard economic cost/benefit analyses may not

Se trata del análisis de la naturaleza económica de los precios de los monopolios, realizado en "El capital financiero", y a la metodología que aplica el autor en su obra maestra para investigar una nueva etapa en la evolución del capitalismo. La importancia del primer tema es evidente porque vivimos en el mundo donde las grandes corporación transnacionales determinan los precios de sus productos en la medida mucho mayor que lo hacían los cárteles y los trusts del inicio del siglo XX. Y en lo que se refiere al segundo elemento, su actualidad esta dada por el hecho de que, al parecer, de nuevo vivimos en el período de grandes cambios del sistema económico del capitalismo que se manifiestan en: el creciente papel del capital ficticio en la reproducción del capital global; el paso en las políticas económicas de la lógica de Bretton Woods a la de neoconservadurismo y de Consenso de Washington; y, en las modificaciones de la forma y del mecanismo del ciclo económico.

    Full Text Available Este trabajo nace de una preocupación profunda por las acciones desplegadas por los países latinoamericanos en las pasadas dos décadas, asociadas a la integración al circuito global de intercambios. La confianza en que el comercio y la vinculación internacional procuraría el umbral máximo de bienestar a sus poblaciones, impulsó reformas estructurales que desmantelarían el carácter autárquico de sus aparatos productivos; proceso que caló profundamente en Argentina. Pero en este camino, en mayor o menor medida, las economías latinoamericanas no lograron un crecimiento económico sostenido, a pesar de haber recreado sus capacidades productivas y practicado su reestructuración política, salvo algunas economías regionales, o el dinamismo que exhibieron algunas ciudades y comunidades locales.

La búsqueda de competitividad en las ciudades y regiones, como una exigencia de la actual agenda pública, deberá guiar los esfuerzos, por un lado, hacia el desarrollo de competencias en los ambientes locales, y por el otro, al fomento de las exportaciones para ganar competitividad internacional. Se hace presente la relevancia de atender a la construcción de la marca de sus productos, como herramientas para la proyección internacional, y el impulso de las ventas en los mercados externos.

  12. Physical activity and abdominal obesity in youth.

    Kim, YoonMyung; Lee, SoJung

    2009-08-01

    Childhood obesity continues to escalate despite considerable efforts to reverse the current trends. Childhood obesity is a leading public health concern because overweight-obese youth suffer from comorbidities such as type 2 diabetes mellitus, nonalcoholic fatty liver disease, metabolic syndrome, and cardiovascular disease, conditions once considered limited to adults. This increasing prevalence of chronic health conditions in youth closely parallels the dramatic increase in obesity, in particular abdominal adiposity, in youth. Although mounting evidence in adults demonstrates the benefits of regular physical activity as a treatment strategy for abdominal obesity, the independent role of regular physical activity alone (e.g., without calorie restriction) on abdominal obesity, and in particular visceral fat, is largely unclear in youth. There is some evidence to suggest that, independent of sedentary activity levels (e.g., television watching or playing video games), engaging in higher-intensity physical activity is associated with a lower waist circumference and less visceral fat. Several randomized controlled studies have shown that aerobic types of exercise are protective against age-related increases in visceral adiposity in growing children and adolescents. However, evidence regarding the effect of resistance training alone as a strategy for the treatment of abdominal obesity is lacking and warrants further investigation.

  14. Clinical application of PET in abdominal cancers

    International Nuclear Information System (INIS)

    2002-01-01

    Clinical application of positron emission tomography (PET) is rapidly increasing for the detection and staging of cancer at whole-body studies performed with the glucose analogue tracer 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FG). Although FDG PET cannot match the anatomic resolution of conventional imaging techniques in the liver and the other abdominal organs, it is particularly useful for identification and characterization of the entire body simultaneously. FDG PET can show foci of metastatic disease that may not be apparent at conventional anatomic imaging and can aid in the characterizing of indeterminate soft-tissue masses. Most abdominal cancer requires surgical management. FGD PET can improve the selection of patients for surgical treatment and thereby reduce the morbidity and mortality associated with inappropriate surgery. FDG PET is also useful for the early detection of recurrence and the monitoring of therapeutic effect. The abdominal cancers, such as gastroesophageal cancer, colorectal cancer, liver cancer and pancreatic cancer, are common malignancies in Korea, and PET is one of the most promising and useful methodologies for the management of abdominal cancers

  15. Abdominal Compartment Syndrome Secondary to Chronic Constipation

    2011-01-01

    Full Text Available Abdominal compartment syndrome (ACS is defined as an elevated intraabdominal pressure with evidence of organ dysfunction. The majority of published reports of ACS are in neonates with abdominal wall defects and in adults following trauma or burns, but it is poorly described in children. We describe the unusual presentation of an 11-year-old boy with a long history of chronic constipation who developed acute ACS requiring resuscitative measures and emergent disimpaction. He presented with a 2-week history of increasing abdominal pain, nausea, diminished appetite and longstanding encopresis. On exam, he was emaciated with a massively distended abdomen with a palpable fecaloma. Abdominal XR confirmed these findings. Within 24 hours of presentation, he became tachycardic and oliguric with orthostatic hypotension. Following two enemas, he acutely deteriorated with severe hypotension, marked tachycardia, acute respiratory distress, and a declining mental status. Endotracheal intubation, fluid boluses, and vasopressors were commenced, followed by emergent surgical fecal disimpaction. This resulted in rapid improvement in vital signs. He has been thoroughly investigated and no other condition apart from functional constipation has been identified. Although ACS secondary to constipation is extremely unusual, this case illustrates the need to actively treat constipation and what can happen if it is not.

    The aim of this study was to describe the CT features of abdominal plasma cell neoplasms. We reviewed CT imaging findings in 11 patients (seven men, four women; mean age 62 years) with plasma cell neoplasms and abdominal involvement. Helical CT of the entire abdomen and pelvis was performed following intravenous administration of contrast material. Images were analyzed in consensus by two radiologists. Diagnoses were made from biopsy, surgery and/or clinical follow-up findings. Multiple myeloma was found in seven patients and extramedullary plasmacytoma in four patients. All patients with multiple myeloma had multifocal disease with involvement of perirenal space (4/7), retroperitoneal and pelvic lymph nodes (3/7), peritoneum (3/7), liver (2/7), subcutaneous tissues (2/7) and kidney (1/7). In three of the four patients with extramedullary plasmacytoma, a single site was involved, namely stomach, vagina and retroperitoneum. In the fourth patient, a double site of abdominal involvement was observed with rectal and jejunal masses. Plasma cell neoplasm should be considered in the differential diagnosis of single or multiple enhancing masses in the abdomen or pelvis. Abdominal plasma cell neoplasms were most frequently seen as well-defined enhancing masses (10/11). (orig.)

  10. Prophylactic antibiotics for penetrating abdominal trauma.

    Brand, Martin; Grieve, Andrew

    2013-11-18

    Penetrating abdominal trauma occurs when the peritoneal cavity is breached. Routine laparotomy for penetrating abdominal injuries began in the 1800s, with antibiotics first being used in World War II to combat septic complications associated with these injuries. This practice was marked with a reduction in sepsis-related mortality and morbidity. Whether prophylactic antibiotics are required in the prevention of infective complications following penetrating abdominal trauma is controversial, however, as no randomised placebo controlled trials have been published to date. There has also been debate about the timing of antibiotic prophylaxis. In 1972 Fullen noted a 7% to 11% post-surgical infection rate with pre-operative antibiotics, a 33% to 57% infection rate with intra-operative antibiotic administration and 30% to 70% infection rate with only post-operative antibiotic administration. Current guidelines state there is sufficient class I evidence to support the use of a single pre-operative broad spectrum antibiotic dose, with aerobic and anaerobic cover, and continuation (up to 24 hours) only in the event of a hollow viscus perforation found at exploratory laparotomy. To assess the benefits and harms of prophylactic antibiotics administered for penetrating abdominal injuries for the reduction of the incidence of septic complications, such as septicaemia, intra-abdominal abscesses and wound infections. Searches were not restricted by date, language or publication status.

    Full Text Available La concepción  que se tenga  del Estado  determina  su régimen  jurídico,  especialmente en cuanto tiene que ver con la actividad y estructura de la Administración, de manera que, además de su actual complejidad, el cambio de paradigma del Estado intervencionista al Estado regulador ha implicado que el ordenamiento jurídico de actuación y organización  de los entes estatales,  particularmente de la rama ejecutiva, se haya tenido que venir ajustando a ese nuevo modelo de Estado, proceso de cambio cuyo contenido y alcance ha sido determinado por las tendencias contemporáneas que lo orientan. La más connotada de esas tendencias es la denominada "huida del derecho administrativo", cuya implementación ha venido operan­ do mediante la adopción directa del derecho privado a la actividad y estructura de la administración pública o a través de la introducción de elementos del derecho privado dentro de las formas institucionales del derecho público, ya sea atendiendo a la naturaleza de la actividad o a la estructura del órgano que la lleva a cabo.

    Full Text Available Analizando la jurisprudencia del Consejo de Estado en lo relacionado con la responsabilidad del Estado por la privación injusta de la libertad, encontramos que la Corporación ha adoptado tres clases de posiciones: La primera, que podemos considerar como subjetiva, en la que equipara esta forma de responsabilidad con el error judicial y el defectuoso funcionamiento de la administración de justicia, pues exige una conducta fallida de la administración de justicia y la presencia de una decisión judicial abiertamente contraria a derecho, como requisitos necesarios para que surja la responsabilidad patrimonial del Estado por prisión provisional injusta. La segunda, que podemos llamar objetiva, sujeta esta forma de responsabilidad, en cuanto a la conducta imputada, a que la persona que ha sido privada de la libertad y que posteriormente ha sido liberada como consecuencia de una decisión de autoridad competente, ésta haya sido fundada en alguna de las causales que contempla el Art. 414 del Decreto Ley 2700 de 1991 (anterior C.P.P, es decir, en que el hecho no ocurrió, o no le es imputable o que no constituyó conducta punible, sin necesidad de valorar la conducta del funcionario judicial y de comprobar si la misma fue errada, ilegal, arbitraria o injusta. La tercera, posición actual de la Corporación, fundamenta la responsabilidad del Estado por privación injusta de la libertad en lo reglado por el artículo 90 de la Constitución Política, esto es, que el Estado es patrimonialmente responsable por los daños antijurídicos que le sean imputables, de manera que si un sujeto es privado de la libertad en desarrollo de una investigación penal y posteriormente es liberado mediante providencia judicial en la que se resuelve desvincularlo del proceso penal, los daños que demuestre y que se deriven de la detención deben serle indemnizados, toda vez que no estaba en el deber de soportarlos.

    The potential role of the abdominal dynamic CT in malignant tumors was evaluated. Among total of 112 cases dynamically studied included were, 22 cases of abdominal malignancies, renal cell carcinoma in 7, hepatocellular carcinoma in 7, metastatic liver tumor in 5, renal pelvic carcinoma in 2, and pancreatic cystadenocarcinoma in one. The results led to the following advantages of the abdominal dynamic CT over conventional CT. (1) The tumor thrombus and the lymphnode involvement could be better demonstrated. (2) The tumor vessels and the tumor stain could be depicted. (3) The extent of the tumor in the parenchyma could be better appreciated. The more invasive catheter angiography would likely to be replaced by the abdominal dynamic CT in the selected case.

    During the last four years 102 patients with abdominal trauma were examined by CT for preoperative evaluation in our hospital. In 35 patients (34 %), the CT scans revealed no abnormal findings. They were all managed conservatively except for one case of perforated small bowel. In 67 patients (66 %) CT revealed evidences of substantial abdominal or retroperitoneal trauma. In 30 of them CT findings were confirmed by surgery. Hepatic injury is usually easily recognized by CT. CT is also useful for the detection of renal or splenic injuries. The majority of those parenchymatous organ injuries were successfully managed with conservative therapy, despite apparent traumatic lesions revealed by CT. Repeat CT scans is proved to be very useful to follow the changes of these traumatic lesions. In conclusion, application of abdominal CT is extremely useful for the initial decision making in treatment of patients with abdominal trauma and for the follow-up observation of injured lesions.

Subjects and methods. Forty-three patients with different causes of inadequate GIT function of various origin and ACS (disseminated peritonitis (45%, pancreatitis (24%, and severe concomitant injury (31% were examined. Group 1 (control received complete parenteral nutritional feeding (n=23; APACHE II scores, 21±4; calculated probability of fatal outcome, 33.5%. In Group II (study, complete parenteral feeding in the first 24 hours after stabilization was supplemented with GIT function support with Pepsisorb (Nutricia in doses of 500, 1000, and 1500 ml on days 1, 2, and 3, respectively (n=20; APACHE II scores, 20±6; calculated probability of fatal outcome, 37.1%. During early enteral nutritional support, the SOFA score was significantly less than that in Group 1 on days 2—3; the oxygenation index significantly increased on day 3; the value of intra-abdominal hypertension decreased to the control values. The positive effect of the GIT function support regimen on regression of the multiple organ dysfunction syndrome (MODS was confirmed by the lowered levels of biological markers (von Willebrand factor (WF and endothelin-1 as markers of endothelial damage of MODS. Correlation analysis showed a direct correlation between the markers of endothelial damage and the SOFA scores (r=0.34; p=0.05 for WF and r=0.49;p=0.03 for endothelin. Conclusion. The GIT function support regimen via early enteral alimentation with Peptisorb, which was initiated in the first 24 hours after admission, is able to level off the manifestations of the early stages of the abdominal compartment syndrome, with the acceptable values of oxygen balance and water-electrolyte and osmotic homeostasis being achieved.

Usually presents a challenging diagnosis and high mortality rates, despite appropriate treatment. OBJECTIVE: To relate a case of a car accident and blunt abdominal trauma with terminal ileum and right colon necrosis. CASE REPORT: After initial procedures, complementary exams showed ribs and humerus fractures. Computerized tomography evidenced aerial distension in small bowel, gastric stasis and hidro-pneumothorax. Hypotension was observed during clinical observation followed by cardiopulmonary arrest, responding to reanimation. At surgery, it was found extensive necrosis of right colon and terminal ileum, and an ileum-transversostomy was performed with primary anastomosis. During the staying in intensive care unit, oliguria, miosis, convulsion and pulseless electric activity happened with death in three days after hospital admission. CONCLUSION: Although uncommon, mesenteric ischemia with venous thrombosis might be secondary to blunt abdominal trauma and must be considered in a bad abdominal evolution.INTRODUÇÃO: Trombose mesentérica, relacionada à trauma é entidade incomum com pobre prognóstico quando seguida de estados de baixo fluxo e choque hipovolêmico.

    Mycotic aneurysms of the abdominal aorta are uncommon, but potentially lethal problems. Clinical subtleties may suggest their presence, but in the past, definitive diagnosis has been dependent on surgical exploration or autopsy findings. A case is presented in which 67-gallium citrate abdominal scanning localized the site of sepsis in an abdominal aortic aneurysm and allowed for prompt and successful surgical therapy. This noninvasive technique is recommended as a adjunct in the diagnosis of mycotic abdominal aortic aneurysms
