    Full Text Available Conocer el estado actual de la legislación Colombiana frente a cinco ámbitos vitales que afrontan las personas con discapacidad: salud, educación, empleo, transporte y accesibilidad; realizando una comparación entre dicha legislación con los resultados encontrados en la encuesta de calidad de vida realizada en el 2012 por el Departamento Administrativo Nacional de Encuestas DANE y el Informe inicial sobre la Convención de los Derechos de las Personas con Discapacidad, se encontró que, aunque existe legislación a favor de los derechos de las personas con discapacidad, el goce efectivo de la salud, la educación, el empleo, el transporte y la accesibilidad es mínimo. 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.

  13. El estrés en personal sanitario hospitalario: estado actual

    José Ignacio Aguado Martín

    2013-06-01

    Full Text Available Introducción: Los riesgos psicosociales y en particular el estrés se han convertido en uno de los principales problemas para la salud y la seguridad laboral. Se ha realizado una revisión de la literatura científica actual sobre el estrés debido a su importancia como riesgo emergente, y la repercusión de este problema en la productividad y el deterioro de la calidad de vida en el personal sanitario que desarrolla su actividad profesional en medio hospitalario, así como intentar identificar los principales métodos de evaluación del estrés actualmente utilizados. Objetivos: Conocer el estado actual del estrés en el personal hospitalario e identificar los principales métodos de evaluación. Metodología: Se realizo una búsqueda bibliográfica exploratoria utilizando las bases de datos Medline, Embase, Scirus, Wok, Psicoinfo, OSH update, Cisdoc, IBECS y LILACS, así como en repositorios como Dialnet, SciELO y Google académico. El periodo de estudio de la bibliografía publicada fue el comprendido entre el año 2009 y 2012 realizándose la última búsqueda el 10 de diciembre de 2012. Resultados: Los niveles de estrés encontrados en los artículos revisados fueron moderados-altos, con diferencias entre las distintas áreas y especialidades. Factores individuales tanto objetivos como subjetivos parecen influir en los grados de estrés. Existe diversidad de métodos utilizados para la evaluación del estrés, la mayoría tienen un nivel de fiabilidad elevado. La producción bibliográfica encontrada es mayor en Asia y Europa. Conclusiones: Los niveles de estrés son elevados en el personal sanitario del hospital ,sobre todo en algunas areas y especialidades, existen una serie de moderadores del grado de estrés como los factores individuales y el ambiente físico y no existe un consenso internacional en el método utilizado para su evaluación.

  15. La vacunación contra pertussis: Estado actual y perspectivas futuras

    Celso Pérez-Bolaños

    2012-01-01

    Full Text Available La tosferina o pertussis es una enfermedad producida por la bacteria Gram negativa Bordetella pertussis y constituye actualmente un problema de salud a escala mundial, siendo la población infantil la más vulnerable dentro de los grupos de riesgo. Suele ser fatal en niños menores de un año, debido a que la tos paroxística característica bloquea las vías respiratorias, lo cual provoca la asfixia y la muerte. Adicionalmente, se observan eventos adversos o complicaciones serias de la enfermedad tales como neumonías bacterianas secundarias, epilepsias, encefalopatía, apnea e hipertensión pulmonar. En la actualidad se aplican programas extensivos de vacunación contra pertussis en todo el mundo, de modo que la enfermedad está considerada como relativamente bien controlada. Según informes de la Organización Mundial de la Salud, cerca del 82 % de toda la población infantil mundial recibió las tres dosis de la vacuna de pertussis en 2008. La vacunación global contra pertussis en ese año evitó cerca de 687 000 muertes por la enfermedad. Sin embargo, se ha observado que ocurre un resurgimiento de ella a escala mundial, así como una prevalencia en zonas del mundo donde la vacunación es pobre. El presente trabajo tuvo como objetivo presentar una revisión acerca de los problemas inherentes a la vacunación contra esta enfermedad en el contexto actual de su resurgimiento a escala universal, la forma de enfocarlos y resolverlos, para su aplicación en Cuba en caso necesario. La vacunación contra pertussis necesita de nuevos enfoques dirigidos a la eliminación de un flagelo que afecta primordialmente a la población infantil, que es el futuro de la humanidad. La solución del problema parece ser la búsqueda de nuevas vacunas más eficaces y la extensión de los esquemas de vacunación a la población de adolescentes y adultos que rodean a los infantes, así como a las mujeres en estado de gestación y a los recién nacidos.

  16. Estado Actual de la Investigación en Historia de la Contabilidad

    2005-06-01

    Full Text Available Es un hecho perfectamente verificable que en las dos últimas décadas se ha producido un desarrollo muy importante en el campo de la investigación histórico-contable en todo el mundo y, en nuestro país, ese desarrollo se ha traducido en el reconocimiento internacional de algunos investigadores que han realizado importantes aportaciones en este campo. En este trabajo hemos querido dedicar un esfuerzo especial en dar respuesta a tres interrogantes que nos podemos plantear antes de dar paso a una investigación en historia de la contabilidad y que son: ¿por qué investigar?, ¿qué investigar? y ¿cómo investigar?, cuyas contestaciones nos irán dando una visión de cual es el estado actual de la investigación en este área. Sin embargo, antes de entrar en ese planteamiento, comenzamos, para centrarnos en el tema, definiendo y delimitando lo que debe entenderse por historia de la contabilidad. Para el desarrollo del trabajo hemos acudido a las opiniones de los investigadores que a nuestro entender más han destacado en los diferentes planteamientos y cuyos trabajos han sido publicados en las revistas de mayor prestigio en este ámbito. In the last two decades there has been an appreciable development in Accounting History research all around the world. In Spain, this development has led to the international recognition of a group of researchers that have made significant contributions to this area. In this paper, we aim to devote a special effort to answer three questions that should be addressed before undertaking an investigation in Accounting History: Why to do research? What to research? How to research? The answer to these questions will provide an overview of the current situation of research in this area. As a previous step we define and delimit what should be understood as Accounting History. To achieve our objective the opinions of researchers that we believe have stood out and whose work has been published in high quality journals

    Full Text Available This article intends to show the current state of the research about structural timber in Spain. An ample compilation of information from people and institutions has been carried out. Information received has been so extensive that a hard work of synthesis has been necesary in order to offer a general and objective vision of the subject.In a few years a new legislative and normative frame has been implanted in Spain, defi ned by the Law of Arrangement of the Construction, the Construction Technical Code and the European Construction Products Directive. In this frame some challenges for the sector arise from the construction and the timber. It is the fi rst time that structural timber is framed within a norm of forced fulfillment, which it supposes not only a challenge but the putting in value of all its potential like structural material.In this frame research necessities have been increased, as well as development and innovation, and it is demostrated by several research iniciatives started in our country, with a clear vocation to respond to the necessities arisen in the sector and to satisfy the raised requirements of security in the norm. In this work, using the compiled information, the research lines on structural timber at the moment in Spain are summarized, as well as their presence in means of national or international diffusion or their direct applications in the industry.Este artículo pretende dibujar un panorama sobre el estado actual de la investigación en torno a la madera estructural desarrollada actualmente en España.

    Full Text Available En el presente documento de trabajo se desarrolla el marco conceptual del turismo de salud y sus dos principales vertientes de estudio: la de la medicina y la turística. 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.

    2012-08-01

    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.

    2013-09-01

    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.

Por lo mismo, el objetivo general del presente trabajo es explorar el tipo de vínculo que existe entre el Estado de Chile y el pueblo mapuche y, el objetivo específico, analizar la situación de los derechos indígenas en el marco del sistema democrático formal actualmente vigente en nuestro país. 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 El bagre de canal (Ictalurus punctatus es uno de los peces endémicos de Norte América con mayor potencial para la acuicultura. A pesar de esto, los datos sobre su distribución actual son escasos y se desconocen muchos aspectos de su dinámica y desempeño productivo. En el presente estudio se reportan los resultados de una búsqueda bibliográfica y análisis de campo que permiten describir la situación actual del bagre de canal con respecto a su distribución geográfica histórica y actual, así como de la problemática que enfrentan los sistemas productivos de esta especie en México. Se identificó la falta de información e indicadores que permitan conocer la extensión de su hábitat natural, movilización o potencial productivo. La calidad y disponibilidad del agua figuran entre las principales problemáticas de la industria; el alimento supone el mayor gasto para los productores y existe gran heterogeneidad de manejo tanto en granjas reproductoras como de engorde, gran parte de la dinámica productiva sigue un modelo de ensayo y error. Se requiere optimizar y homologar los procesos del sistema productivo de bagre de canal, así como caracterizar correctamente las poblaciones domésticas y silvestres para aprovechar al máximo su potencial.

    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 El cambio producido en el sector de la salud mental en los últimos 20 años ha sido extraordinario. La primera legislatura socialista, con Ernest Lluch al frente del Ministerio de Sanidad y haciendose eco de un sentimiento generalizado entre amplios grupos de profesionales, estableció las condiciones para el cambio de la salud mental en España: el Informe de la Comisión Ministerial para la Reforma Psiquiátrica (1985 y la Ley General de Sanidad (1986, que promovió la universalización del derecho a la protección de la salud. Unos años después, el llamado Informe Abril (1991 se hizo eco de una nueva sensibilidad por introducir, no sin dificultades, un mayor rigor en la organización y gestión del sistema público de salud, lo que sería objeto de una relectura interesada y de corte conservadora por parte del primer gobierno del Partido Popular a través de la creación de la Subcomisión Parlamentaria para la consolidación y modernización del sistema sanitario (1997. Sus efectos en goteo sobre nuestro sector delatan un progresivo estancamiento tanto en el desarrollo de servicios asistenciales como en la propia discusión intelectual sobre las nuevas necesidades y demandas ciudadanas. Es necesario reavivar el debate sobre la problemática actual de las políticas de salud mental y sus nuevas posibilidades en el marco de los cambios económicos y sociales habidos en estos últimos años. Para ello se ha seguido un análisis de corte funcionalista basado en las técnicas utilizadas en el ámbito empresarial para desarrollar análisis estratégicos previos a la introducción de cambios en la gestión de dichas organizaciones.

    Full Text Available La única población sobreviviente del huemul en Chile central (Los Nevados de Chillán se encuentra en un descenso clásico hacia la extinción. Se utilizan los datos de prospecciones en terreno por el período entre 1975 a 2002 para estimar el tamaño, la estructura espacial y la tendencia de la población. Un análisis de la población en 1997 arrojó un mínimo de 60 huemules en 12 sitios, y una declinación de un 58% en la población durante un período de dos décadas. Prospecciones recientes entre 1998-2002 indican que la población de huemules ha continuado disminuyendo a 40 individuos en 11 sitios, lo que representa un descenso adicional de un 33%. Desde el año 1987, los huemules han desaparecido de 5, y posiblemente 8, sitios de hábitat primario. Solamente un sitio, el del Río Niblinto que es protegido, muestra un grupo del huemul más o menos estable. Las amenazas al huemul y a su hábitat, tal como los impactos del ganado doméstico, la urbanización, el desarrollo recreativo, la presencia de perros domésticos y las actividades industriales siguen sin disminución en la gran mayoría de los 26 sitios de hábitat primario necesario para la recuperación del huemul. Los datos actuales muestran claramente que una compaña de conservación más amplia es necesaria para resguardar y recuperar la especie en Chile central. Se requieren proteger los sitios de hábitat primario y los corredores conectantes de hábitat del huemul. Para realizar tal objetivo, se necesitan un fuerte compromiso e inversión financiera del gobierno y del sector privado. La creación de un nuevo parque nacional o gran reserva para el huemul y la biodiversidad en el sector de Los Nevados de Chillán, con beneficios relacionados al turismo, la educación pública, e investigaciones científicas, podría ayudar a atraer los recursos financieros que se necesitan para un programa exitoso de conservaciónABSTRACT The only surviving population of huemul in central

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.

    1992-12-01

    Full Text Available The lack of data on prehistoric metallurgical activities in Málaga made local prehistorians think that all the metal artefacts recovered in the province were of non-local origin. As a result of a project funded by the Junta de Andalucía, new data have been collected and we can begin to outline the development and socioeconomic importance that metal technologies have in different parts of Málaga throughout prehistory.

    La práctica inexistencia de datos sobre actividades metalúrgicas prehistóricas en Málaga y el vacío investigador que sobre este aspecto existía en la provincia habían creado un estado de opinión entre los prehistoriadores locales tendente a considerar como de origen extraprovincial la totalidad de los artefactos metálicos prehistóricos recuperados. Como resultado de un proyecto subvencionado por la Junta de Andalucía, estos datos que faltaban comienzan ahora a ser recuperados, y se puede empezar a trazar un esbozo general del desarrollo e importancia socieconómica que este grupo de tecnologías tuvieron en los diversos ambientes geográficos de la provincia de Málaga durante la prehistoria.

    The bio stratigraphic studies of the Brazilian sedimentary basins have providing a support for the exploratory research of energetic and mineral resources, in particular at the continental margin. From new discoveries of hydrocarbon accumulations at the Santos and Campos basins, the south portion of the Brazilian continental margin were converted in an important target of the exploration. Therefore, the bio stratigraphic refinement is necessary to detect gaps and to promote an increment on the precision of the lateral correlations in the delimitation and spatial analysis of the potential reservoirs. The actual stage of the bio-chronostratigraphic framework of the Pelotas Basin is presented herein, focusing on its application to the reservoir prospection. The main questions and lacunae on the knowledge are also discussed. In terms of bio stratigraphy, the Pelotas Basin remains poorly evaluated, despite publication of important works on the bio stratigraphy are known since the 1960's. A comparison of bio stratigraphic schemes proposed for the Tertiary section of the basin allows the inference of diverse hiatuses, identified by the absences of bio zones. Hiatuses identified in the {sup 87}Sr/{sup 86}Sr curve, suggest their relationship with discontinuities in the deposition. Discrepancies between the proposed schemes can be attributed to the particular resolution of the different groups used, the variations in the bio stratigraphic criteria and the sampling interval, influencing the bio stratigraphic resolution and therefore its potential as a correlation tool.

    2008-01-01

    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.

    Abdominal pain is one of the most common complaints by patients, and assessment of abdominal pain and associated symptoms can be challenging for home healthcare providers. Reasons for abdominal pain are related to inflammation, organ distention, and ischemia. The history and physical examination are important to narrow the source of acute or chronic problems, identify immediate interventions, and when necessary, facilitate emergency department care.

  4. Abdominal trauma

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

  5. Abdominal trauma

    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

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.Em alguns meios de comunicação social foi veiculada informação sobre supostos riscos para a saúde, especialmente em contexto escolar, com origem na exposição às Radiofrequências (RF emitidas pelos sistemas de telecomunicação sem fios (Wi-Fi na sua abreviatura em inglês.

  8. Abdominal Sepsis.

    De Waele, Jan J

    2016-08-01

    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.

    Juliana Alosilla

    2006-12-01

    Full Text Available Se realiza un análisis del estado de conservación de un conjunto de sitios de la localidad arqueológica de La Ciénaga que se encuentran muy deteriorados. El deterioro es producido por procesos naturales, entre los cuales el más importante es la erosión hídrica, y por procesos culturales, entre los que se destaca el saqueo. La desertización del ambiente es un proceso debido en gran medida a factores humanos que inciden en forma indirecta en la destrucción de los sitios arqueológicos. El patrimonio cultural juega un rol importante en la provisión y construcción de un sentido de comunidad, de pasado compartido y de identidad social. Desde esta perspectiva se considera al análisis del estado de conservación de los sitios y materiales arqueológicos como un paso inicial imprescindible para una gestión integral que involucre a la investigación arqueológica y a las acciones dirigidas a conservarlos y darlos a conocer.

    Full Text Available Se revisó el estado del conocimiento sobre la distribución de la nutria neotropical (Lontra longicaudis para el estado de Durango, México, con base en bibliografía previa y 2 nuevos registros basados en excretas. Sólo 3 de los reportes históricos disponibles estuvieron documentados con evidencia física u observaciones. El análisis de las excretas reveló principalmente restos de peces, en su mayoría nativos. Catostomus plebeius, Campostoma ornatum, Gila conspersa, Carassius auratus y Scartomyzon austrinus no se habían registrado previamente en la dieta de L. longicaudis en México. La presencia de la nutria neotropical en las partes altas y media de 3 grandes cuencas (Mezquital-San Pedro, Nazas y Grande de Santiago apunta a la importancia de preservar las cabeceras de estos ríos, donde la nutria puede persistir aún cuando sus partes bajas tengan un fuerte efecto antropogénico.An update on the state of knowledge on the neotropical otter (Lontra longicaudis for the state of Durango, Mexico is presented based on the revision of literature reports and the addition of 2 new records. Upon revision, only 3 of the previous reports are supported by physical evidence or observations; and 2 more are newly documented records based on scats. Analysis of these samples indicated that the main items consumed by otters in Durango were mostly native fishes. Catostomus plebeius, Campostoma ornatum, Gila conspersa, Carassius auratus and Scartomyzon austrinus had not been recorded previously in the neotropical otter's diet. Neotropical otters are able to persist at the headwaters of at least 3 major basins (San Pedro-Mezquital, Nazas, and Grande de Santiago even though strong anthropogenic disturbances have already occurred downstream, thus pointing to the need of effective conservation strategies for these areas.

    regional intravenosa merece ter sua história conhecida e a data não pode passar despercebida e sim ser lembrada e comemorada.JUSTIFICATIVA Y OBJETIVOS: La anestesia regional intravenosa completa este año en 2008 un siglo de existencia. Siendo una técnica anestésica ampliamente utilizada, se justifica recordar el hecho, festejar la fecha, recordarle a los anestesiólogos brasileños el proceso evolutivo por el cual ella ha pasado, principalmente en los últimos 40 años, y prestarle un homenaje a aquel que la inició: August Karl Gustav Bier. CONTENIDO: El texto relata el origen de la anestesia locorregional en general y de la anestesia regional intravenosa en particular, desde la introducci��n del torniquete de miembros y del descubrimiento y del perfeccionamiento de las agujas de punción, de las jeringuillas y de los anestésicos locales. Se describen los detalles técnicos inicialmente utilizados por Bier y los conceptos fisiopatológicos y clínicos por él emitidos a principios del siglo XX. Retrata la evolución inicial y de las décadas siguientes de la anestesia regional intravenosa, cita los pioneros nacionales e internacionales que la usaron, explica las razones de su relativamente tardío estudio científico, describe los principales aportes que hasta hoy existen para su utilización eficiente y segura. Finalmente, narra el estado actual de los principales conocimientos adquiridos a lo largo del tiempo, como el mecanismo e el local de acción del anestésico y de la isquemia, uso de soluciones anestésicas modernas, perfeccionamiento de la analgesia postoperatoria y del bloqueo motor, conceptos farmacocinéticos y fisiopatológicos y una mejor interpretación de las posibles principales complicaciones. CONCLUSIONES: La anestesia regional intravenosa es una técnica anestésica creada por A. K. G. Bier hace exactamente 100 años. Evolucionó lentamente y bastante poco en la primera mitad del siglo XX y mucho en los últimos años, gracias a innumerables

    2005-10-01

    Full Text Available Colorectal cancer is the most frequent tumor of the digestive tract. The high incidence of abdominal dissemination; the poor prognosis of these patients, with median survival consistently ranging from 5 to 9 months in all studies of peritoneal carcinomatosis from colorectal cancer; the failure of adjuvant systemic chemotherapy treatment with a maximal survival of 18 months despite the development of new cytostatic drugs, and new combinations of use, make it crucial to search for and develop new treatment strategies. We review the principles of Sugarbaker´s treatment protocol, which involves the combination of maximum cytoreductive radical oncological surgery for the treatment of all macroscopically disseminated disease with maximum perioperative intraperitoneal intensification chemotherapy to treat residual microscopic disease. We present the results of several scientific papers, all of them phase II studies with more than 10 patients treated, published in the medical literature by the main groups working in this line of treatment, together with the only phase III study reported and published so far, and finally the results of a recently reported retrospective international multicenter study. With this new alternative therapeutic approach, overall mean survival is 40% at 36 months, and 20% at 5 years. Based on these results, this new therapeutic approach is proposed as the treatment of choice for these unfortunate patients.El cáncer colorrectal es el tumor más frecuente del tracto digestivo. La alta incidencia de diseminación abdominal, el pobre pronóstico de estos pacientes con una mediana de supervivencia entre 5 y 9 meses demostrada repetidamente en todos los estudios de carcinomatosis peritoneal por cáncer colorrectal, el fracaso de los tratamientos sistémicos adyuvantes con quimioterapia con supervivencias máximas de 18 meses independientemente del desarrollo de nuevas drogas citostáticas y las nuevas combinaciones o formas de uso

    2008-03-01

    Full Text Available Background: Ample use of serological markers of high sensitivity and specificity led to relevant changes in the epidemiology of celiac disease. The impact of these changes in our country is poorly known. Aim: To assess the diagnostic procedures, clinical presentations and follow up of celiac disease as conducted in current pediatric practice. Material and methods: A multicentric retrospective study of patients diagnosed between 2000 and 2005 in five pediatric hospitals in Santiago, Chile. Data was obtained from clinical records, recorded in electronic spreadsheets and analyzed by descriptive statistics. Results: Seventy four of 83 identified patients fulfilled the inclusion criteria and were analyzed. Mean time to reach the diagnosis was 2.1 years. Cases younger than 10 years presented digestive manifestations such as chronic diarrhea and abdominal distension. Twenty one percent of older patients had atypical presentations (mainly short stature, refractory anaemia. Ten percent of cases were screened because a first degree relative had celiac disease. All patients had significant duodenal/jejunal lesion. IgA-antiendomysial antibodies (n =65 and IgA-antigliadin antibodies (n =23 were the most commonly used screening tests used but often, they were not available for follow up. A second biopsy was planned in all patients but only 26 had it due to repeated dietary transgressions, often due to unnoticed consumption of gluten in poorly labeled products. Conclusions: Digestive manifestations were the main presentation form for celiac disease among patients under 10 years of age. Atypical symptoms become relevant in patients older than 10 years. Antiendomysial and antitransglutaminase antibody measurement should be incorporated for routine screening and follow up of celiac disease in public hospitals. To improve food labeling about their gluten content is needed

    Full Text Available Desde la creación del primer Museo Nacional de Brasil hasta la actualidad, el concepto y los objetivos de sus museos fueron modificándose y transformándose en función de las políticas predominantes del país. Por mucho tiempo éstas fueron exclusivas y apelaban a conservar el patrimonio de las elites brasileñas. Desde el 2000, las políticas museológicas y patrimoniales apuntaron hacia una democratización de los museos y un mayor acceso de información para su administración. Sin embargo, muchos museos regionales aún deben lidiar con una serie de problemas presupuestarios y de recursos humanos que les dificulta desarrollar y mejorar la conservación y divulgación del patrimonio que albergan.

  18. Abdominal trauma

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

    Full Text Available La horticultura en Colombia comprende las áreas de floricultura, fruticultura, olerícultura, producción de plantas aromáticas y medicinales y la horticultura urbana. 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.

  2. Estado actual en el tratamiento de la enfermedad de Chagas

    WERNER APT B

    2011-02-01

    Full Text Available Efficient drugs against Chagas' disease must have an effect on the amastigote forms or intracellular reproduction elements of Trypanosoma cruzi (T. cruzi. Trypomastigote and epimastigote forms derive from the former and their response to medications is less marked. The only drugs used in humans are nifurtimox (NF and benznidazole (BNZ. Other useful medications are allopurinol and itraconazole. NF acts producing free radicals and BNZ inhibits the synthesis of macromolecules. There is consensus that Chagas' disease must be treated in all its periods, since T.cruzi DNA is detected by polymerase chain reaction in chronic cases, even when microscopy is negative. The pharmacological treatment modifies the natural evolution of the disease. It also helps to solve a public health problem, considering that there is a high number of subjects with Chagas' disease. Subjects with chronic chagasic cardiomyopathy with terminal heart failure are the only cases without indication for treatment. Due to the digestive and skin secondary effects of the drugs, treated patients must be controlled clinically and with complete blood counts and hepatic proiles before, during and after the therapy. Approximately 30% of patients will experience secondary effects. Children have a better tolerance to the drugs. Congenital or acquired acute, intermediate and chronic cases should be treated.

  12. Sonography of blunt abdominal trauma

    Sonographic examination of the abdomen after blunt abdominal trauma represents a rapid and effective diagnostic method without bothering the patient. It has proved its value not only in the confirmation or exclusion of free fluid in the abdomen caused by liver of spleen rupture, but also in such cases actually it replaces peritoneal lavage or exploratory laparotomy. It is also qualified for diagnosis of intraparenchymal or subcapsular hemorrhages, intraperitoneal as well as retroperitoneal and for follow up. In particualr delayed bleedings including the risk of a retarded organ rupture can be detected early. A failure rate of 1.4% in 282 sonographically examined cases of blunt abdominal trauma further confirms the reliability of this method. (orig.)

    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.

    2011-01-01

    Full Text Available El trabajo científico se fundamenta en un conjunto estructurado de pasos que aseguran la objetividad y la precisión de cada investigación. Así, aproximarse a un constructo teórico que ha sido examinado a través de la reflexión filosófica del derecho y la política, coadyuva a la formulación de supuestos. En este caso, el manuscrito permite mostrar cómo develar tres enfoques del Estado de Derecho. Es así como nos ocupamos de indagar por qué y para qué se describen las nociones o principios delEstado deDerecho. Para los liberales el concepto de Estado democrático no implica necesariamente, por símismo, la condición de un Estado de Derecho. Por un lado encontramos que el Estado Social de Derecho responde a la promoción de una mayor garantía de los derechos económicos, sociales y culturales. Partiendo de esa premisa, se analizan tres tipologías de estado de derecho para adecuarlo a las configuraciones actuales del mundo global.

    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.

  16. Abdominal MRI in childhood

    MRI provides diagnostic information in multiple abdominal diseases in childhood. Additional information to sonographic findings can be achieved in the diagnosis of abdominal malformation as well as in several inflammatory processes. In childhood cancer imaging MRI is essential at the beginning as well as during therapy to assess response to therapy. Because of radiation protection MRI has to replace CT in abdominal imaging in children. Some technical details have to be considered when children are examined. (orig.)

    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.
    KEY WORDS: data processing, curve fitting, Splines, digital filtering, Fourier Series, Kinematics

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy. PMID:9737070

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis

  12. Abdominal Dual Energy Imaging

    Sommer, F. Graham; Brody, William R.; Cassel, Douglas M.; Macovski, Albert

    1981-11-01

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

    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

  15. Abdominal Vascular Catastrophes.

    Singh, Manpreet; Koyfman, Alex; Martinez, Joseph P

    2016-05-01

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

  17. Adult abdominal hernias.

    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.

  3. Component separation in abdominal trauma.

    Rawstorne, Edward; Smart, Christopher J; Fallis, Simon A; Suggett, Nigel

    2014-01-01

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

  4. Value of abdominal CT in the emergency department for patients with abdominal pain

    The purpose of our study is to demonstrate the value of CT in the emergency department (ED) for patients with non-traumatic abdominal pain. 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.)

  5. CT of abdominal trauma

    Soon after it became available for clinical use, cranial CT became the method of choice for evaluating head trauma. Only relatively recently have newer generation full-body scanners been installed at major trauma centers, but experience is rapidly being gained in the utilization of CT for abdominal trauma. CT has proved highly accurate in diagnosing a wide variety of injuries to both intra- and retroperitoneal organs in pediatric and adult patient populations. The impact has been evident not only in decreasing utilization of other diagnostic tests, such as angiography, but also in practical management decisions, such as whether to perform exploratory laparotomy. This chapter details the authors' approach to evaluation of abdominal trauma by CT

  6. The blunt abdominal trauma

    Up to 1970 the number of patients suffering from blunt abdominal trauma showed a substantial increase. In more than 50% of all cases there are additional injuries. The most important factor influencing the prognosis of these patients is the early and correct indication for operation and the avoidance of unnecessary laparotomies. As a primary aim in diagnosis one should consider the recognition of an intraperitoneal bleeding without risk for the patient. Peritoneal lavage as an invasive method with low complication rates has proved good. First reports also show good results using the sonography of the abdomen. The recognition of the injured organ allows a carefully directed operation. Concerning the prognosis it is of minor importance. The diagnosis in patients with blunt abdominal trauma at the university clinic of Freiburg consists of: sonography, followed in positive cases by laparotomy or angiography and laparotomy. In cases with questionable results a lavage is done. (orig.)

  8. The abdominal circulatory pump.

    Andrea Aliverti

    Full Text Available Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume does not so that the blood volume shifted between trunk and extremities (Vbs is the difference between changes in trunk and body volume. This is so because both trunk and body volume change identically with breathing and gas expansion or compression. During tidal breathing Vbs was 50-75 ml with an ejection fraction of 4-6% and an output of 750-1500 ml/min. Step increases in abdominal pressure resulted in rapid emptying presumably from the liver with a time constant of 0.61+/-0.1SE sec. followed by slower flow from non-hepatic viscera. The filling time constant was 0.57+/-0.09SE sec. Splanchnic emptying shifted up to 650 ml blood. With emptying, the increased hepatic vein flow increases the blood pressure at its entry into the inferior vena cava (IVC and abolishes the pressure gradient producing flow between the femoral vein and the IVC inducing blood pooling in the legs. The findings are important for exercise because the larger the Vbs the greater the perfusion of locomotor muscles. During asystolic cardiac arrest we calculate that appropriate timing of abdominal compression could produce an output of 6 L/min. so that the abdominal circulatory pump might act as an auxiliary heart.

    2013-01-01

    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.

    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.

  16. [Differential diagnosis of abdominal pain].

    Frei, Pascal

    2015-09-01

    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. PMID:26331201

  19. Hypnosis for functional abdominal pain.

    Gottsegen, David

    2011-07-01

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

  1. Clinical and CT imaging features of abdominal fat necrosis

    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.

  2. Practical pediatric abdominal CT

    This course is designed to help the radiologist in a hospital setting successfully approach abdominal CT in the infant and child. Emphasis is placed on techniques necessary for a high-quality examination of the upper abdomen, as applied to common pediatric problems such as trauma, tumor, and infection. Material is presented on technical considerations, including patient sedation, preparation, and potential pitfalls and helpful hints for imaging. An emphasis is placed on dynamic scanning with table incrementation. The section on trauma focuses on an approach to imaging the abdomen in the injured child, typical injuries, patterns of injury in the upper abdomen, and why CT is the best imaging modality for blunt upper abdominal trauma. The discussion of tumor imaging reviews the appearance of typical childhood neoplasia including Wilms tumor, neuroblastoma, non-Hodgkin and Burkitt lymphoma, and disseminated solid tumors such as rhabdomyosarcoma. The authors emphasize what to look for and where, both on initial and on later (for recurrences) examinations. The discussion of infection addresses detection of abscesses and occult infections in children, as well as imaging of abscesses prior to intervention

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

    Marincek, B. [Institute of Diagnostic Radiology, University Hospital Zurich, Raemistrasse 100, 8091 Zurich (Switzerland)

    2002-09-01

    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.)

  4. Abdominal Burkitt lymphoma

    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)

  9. Penetrating abdominal trauma.

    Henneman, P L

    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

  11. Economics of abdominal wall reconstruction.

    Bower, Curtis; Roth, J Scott

    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.

  15. Updates on abdominal desmoid tumors

    2007-01-01

    Desmoid tumor is a monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. This connective tissue hyperplasia infiltrates locally, recurs frequentiy after resection but does not metastasize. Abdominal desmoid occurs sporadically, in association with some familial syndromes and often represents a clinical dilemma for surgeons. The enigmatic biology and anatomical location of abdominal desmoids make treatment recommendations difficult. This distinct pathological entity is reviewed with a specific focus on aetiology and management.

  2. Detection of abdominal bleeding in blunt abdominal trauma

    Arterial hemorrhage is the most serious immediate complication of blunt abdominal trauma. This paper discusses the detection and localization of active hemorrhage in nonpenetrating injury, as a modification of the technique using technetium-99m sulfur colloid to localize the site of active bleeding in the gastrointestinal tract. Any imaging protocol for suspected hepatosplenic injury can be easily modified to search for active intra-abdominal hemorrhage. The timely detection of unsuspected bleeding improves patient management by allowing the surgeon to reorder his or her treatment priorities. The early detection of clinically unsuspected intra-abdominal, retroperitoneal, or pelvic hemorrhage will identify those patients who may need more definitive diagnostic procedures, interventional angiography for control of bleeding, or surgical intervention. The 500,000-count view of the abdomen and pelvis can be easily incorporated into any existing trauma protocol using technetium-99m sulfur colloid, is of proven value, and adds little additional time to the study

    AIM: To evaluate the clinical, radiological and microbiological properties of abdominal tuberculosis (TB) and to discuss methods needed to get the diagnosis.METHODS: Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital,Istanbul, Turkey were evaluated prospectively. Complete physical examination, medical and family history, blood count erythrocyte sedimentation rate, routine biochemical tests,Mantoux skin test, chest X-ray and abdominal ultrasonography (USG) were performed in all cases, whereas microbiological examination of ascites, upper gastrointestinal endoscopy, colonoscopy or barium enema, abdominal tomography, mediastinoscopy, laparoscopy or laparotomy were done when needed.RESULTS: The median age of patients (14 females, 17males) was 34.2 years (range 15-65 years). The most frequent symptoms were abdominal pain and weight loss.Eleven patients had active pulmonary TB. The most common abdominal USG findings were ascites and hepatomegaly. Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2 %). Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients. Colonoscopy performed in 20 patients showed ulcers in 9 (45 %), nodules in 2 (10 %)and, stricture, polypoid lesions, granulomatous findings in terminal ileum and rectal fistula each in one patient (5 %).Laparoscopy on 4 patients showed dilated bowel loops,thickening in the mesentery, multiple ulcers and tubercles on the peritoneum. Patients with abdominal TB were divided into three groups according to the type of involvement.Fifteen patients (48 %) had intestinal TB, L1 patients (35.2 %) had tuberculous peritonitis and 5 (16.8 %)tuberculous lymphadenitis. The diagnosis of abdominal TB was confirmed microbiologically in 5 (16 %) and histopathologically in 19 patients (60.8 %). The

    A 26-years-old Indian male was admitted to hospital with loss of weight and vague abdominal pain of several weeks duration. Ultrasonography and computed tomography showed several expansive lesions near the pancreatic head, probably representing enlarged lymph nodes. A few milliliters of yellowish pus were aspirated by ultrasound guided aspiration. Microscopic examination of the pus showed trophozoits, and mycobacterium tuberculosis subsequently grew from the pus culture. Abdominal tuberculosis is a rare condition, particularly in the pancreas and the peripancreatic region. The report stresses the importance of considering the possible coexistance of more than one infectious disease in patients from endemic areas. 21 refs., 2 figs.

  11. Abdominal radiation causes bacterial translocation

    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

  13. Radiological evaluation of abdominal trauma

    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

    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.

    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.

  19. Plain abdominal film and abdominal ultrasound in intestine occlusion

    Plain film of the abdomen is widely used in the diagnostic evaluation of intestinal occlusion. Even though this technique can yield a panoramic and high-resolution view of gas-filled intestinal loops, several factors, such as type and duration of occlusion, neurovascular status of the intestine and general patient condition, may reduce the diagnostic specificy of the plain film relative to the organic or functional nature of the occlusion. From 1987 to 1989, fifty-four patients with intestinal occlusion were studied combining plain abdominal film with abdominal ultrasound (US). This was done in order to evaluate whether the additional information obtained from US could be of value in better determining the nature of the ileus. US evaluation was guided by the information already obtained from plain film which better demonstrates gas-filled loops. The results show that in all 27 cases of dynamic ileus (intestinal ischemia, acute appendicitis, acute cholecistis, acute pancreatitis or blunt abdominal trauma) US demonstrates: intestinal loops slightly increased in caliber, with liquid content, or loops containing rare hyperechoic particles, intestinal wall thickening and no peristalsis. In 27 cases of acute, chronic or complicated mechanical ileus (adhesions, internal hernia, intestinal neoplasm, peritoneal seedings) US shows: 1) in acute occlusion: hyperperistaltic intestinal loops containing inhomogeneous liquid; 2) in chronic occlusion: liquid content with a solid echigenic component; 3) in complicated occlusion: liquid stasis, frequent increase in wall thickness, moderate peritoneal effusion and inefficient peristalsis. In conclusion, based on the obtained data, the authors feel that the combination of plain abdominal film and abdominal US can be useful in the work-up of patient with intestinal occlusion. The information provided by US allows a better definition of the nature of the ileus

  2. Dehydration related abdominal pain (drap)

    Objective: To describe the frequency of dehydration as a medical cause of acute abdomen. Subjects and Methods: All the patients reporting with abdominal pain to the surgical outpatient department or the emergency department were reviewed in the study. The clinical findings in all these cases were studied along with the mode of their management and outcome. Results: Of all the patients presenting with abdominal pain, 3.3% (n=68) were suffering from dehydration related abdominal pain. They were predominantly males in a ratio of 8.7: 1, mostly in the 2nd and 3rd decades of their lives. All these cases were suffering from acute or chronic dehydration were provisionally diagnosed by general practitioners as 'acute abdomen' and referred for surgical consultation. Associated symptoms included vomiting in 42.6%, backache in 91.2%, headache in 95.6%, and pain in lower limbs in 97.1 % of the cases. 83.8% required indoor management with intravenous fluids. All the patients became asymptomatic with rehydration therapy. Conclusion: Dehydration is a possible cause of severe abdominal pain. There is a need to educate the general public about the benefits of adequate fluid intake. (author)

    Bossuyt Patrick MM

    2007-08-01

    Full Text Available Abstract Background The acute abdomen is a frequent entity at the Emergency Department (ED, which usually needs rapid and accurate diagnostic work-up. Diagnostic work-up with imaging can consist of plain X-ray, ultrasonography (US, computed tomography (CT and even diagnostic laparoscopy. However, no evidence-based guidelines exist in current literature. The actual diagnostic work-up of a patient with acute abdominal pain presenting to the ED varies greatly between hospitals and physicians. The OPTIMA study was designed to provide the evidence base for constructing an optimal diagnostic imaging guideline for patients with acute abdominal pain at the ED. Methods/design Thousand consecutive patients with abdominal pain > 2 hours and Discussion This study aims to provide the evidence base for the development of a diagnostic algorithm that can act as a guideline for ED physicians to evaluate patients with acute abdominal pain.

  10. How People Actually Use Thermostats

    Meier, Alan; Aragon, Cecilia; Hurwitz, Becky; Mujumdar, Dhawal; Peffer, Therese; Perry, Daniel; Pritoni, Marco

    2010-08-15

    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.

  11. Intestinal contrasting in abdominal CT

    In 56 patients undergoing abdominal CT the gastro-intestinal tract was defined by negative contrast instead of the conventional positive contrast from an iodine containing contrast medium. The contrast material was a 2 1/2% mannitol solution and was used for filling the rectum. Filling of the gastro-intestinal tract was of similar quality to that obtained with positve contrast media. The number of artifacts due to high contrast boundaries was slightly greater with the negative contrast than if would have been with positive contrast. Differentiation of the gastro-intestinal tract from other abdominal organs was equally good for both methods. The negative contrast method was poor in diagnosing cystic tumours but proved much better than positive contrast for evaluating the wall of the gastro-intestinal tract. (orig.)

We have to take care that the similar CT findings include the opposite results to need surgery and not. (author)

  15. [A case of abdominal wall actinomycosis].

    Kim, Kyung Hoon; Lee, Jin Soo; Cho, Hyeong Jun; Choi, Seung Bong; Cheung, Dae Young; Kim, Jin Il; Lee, In Kyu

    2015-04-01

    Actinomycosis is a chronic suppurative granulomatous infectious disease caused by actinomyces species that is characterized by formation of characteristic clumps called as sulfur granules. Abdominal actinomycosis is a rare disease and is often difficult to diagnose before operation. Abdominal actinomycosis infiltrating into the abdominal wall and adhering to the colon is even rarer. Most abdominal actinomycosis develops after operation, trauma or inflammatory bowel disease, and is also considered as an opportunistic infection in immunocompromised patient with underlying malignancy, diabetes mellitus, human immunodeficiency virus infection, etc. Actinomycosis is diagnosed based on histologic demonstration of sulfur granules in surgically resected specimen or pus, and treatment consists of long-term penicillin based antibiotics therapy with or without surgical resection. Herein, we report an unusual case of abdominal wall actinomycosis which developed in a patient after acupuncture and presented as abdominal wall mass that was first mistaken for abdominal wall invasion of diverticulum perforation.

  17. Abdominal wound closure: current perspectives

    Williams ZF

    2015-12-01

    Full Text Available Zachary F Williams, William W Hope Department of Surgery, South East Area Health Education Center, New Hanover Regional Medical Center, Wilmington, NC, USA Abstract: This review examines both early and late wound complications following laparotomy closure, with particular emphasis on technical aspects that reduce hernia formation. Abdominal fascial closure is an area of considerable variation within the field of general surgery. The formation of hernias following abdominal wall incisions continues to be a challenging problem. Ventral hernia repairs are among the most common surgeries performed by general surgeons, and despite many technical advances in the field, incisional hernia rates remain high. Much attention and research has been directed to the surgical management of hernias. Less focus has been placed on prevention of hernia formation despite its obvious importance. This review examines the effects of factors such as the type of incision, suture type and size, closure method, patient risk factors, and the use of prophylactic mesh.

  18. Acute Abdominal Pain in Children.

    Reust, Carin E; Williams, Amy

    2016-05-15

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

    2009-12-01

    Full Text Available La dificultad con la que nos encontramos cuando queremos definir Estado de Bienestar es considerable, ya que es un concepto muy generalizado que se utiliza para indicar varias acciones o actitudes del Estado, entre ellas la intención de redistribución del ingreso para ayudar a los más pobres. Es por ello que en este ensayo intentaremos reflexionar sobre el concepto mismo de Estado de Bienestar para poder abordar luego su evolución y su actual crisis. 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. El propósito es relacionar estas interconexiones y procesos con la crisis del Estado de Bienestar y su posible transformación.___________________ABSTRACT:Difficulty when we want to define Welfare State is considerable, because is a concept very generalized that is used to indicate several actions or attitudes of the State, among them the redistribution intention to help poorest. It is for that reason that in this test we will try to reflect on the same concept of Welfare State to be able to soon approach its evolution and its present crisis. Also the globalization concept shares the characteristics mentioned since it is used to denominate too many things, but we understand it here like economic, social, cultural and political interconnections, the networks conformed by all this built the framework for of social phenomena and the processes that often extend the national borders. The intention is to relate these interconnections and processes to the crisis of the Welfare State  and their possible transformation.

    2014-02-01

    Full Text Available Extrauterine abdominal pregnancy is extremely rare and is frequently missed during antenatal care, despite the routine use of obstetrics ultrasound. A 23 year old primigravida at 39 weeks of gestation was admitted to the department on December 2 , 2012, in routine hour with transverse lie with oligohydramnios. On examination her vitals and laboratory investigation were within normal limits . One of the ultrasonographic scanning done by radiologist at 35 wk. 3 days gestation demonstrated a single live intrauterine fetus of CGA 33 wk. 1 day with transverse lie , fundal gr II placenta and AFI - 10 cm. Ultrasonography done at the department on the day of admission demonstrated single live intrauterine fetus with transverse lie and AFI - 3.8 cm and EFW 2.4 Kg and placenta was right anterior.. She was planned for elective caesarean section on account of transverse lie and oligohydramnios at term. At laparotomy the following findings were made: Secondary abdominal pregnancy arising from right tubal ectopic rupture and making pseudogesta tional sac with meconium stained liquor. Omentum , right tube and ovary were adhered to sac. The uterus and left tube and ovary were healthy and normal . Other abdominal organs were normal. A 1.5 Kg live male baby with good Apgar score and incompletely formed mandible extracted from pseudo gestational sac. There was significant bleeding from pseudogestational sac and patient went in shock during intraoperative period. One unit whole blood transfused during intraoperative period. Placenta was adherent to the pseudogestational sac so Psudogestational sac was removed with placenta in situ and right sided salpingo - o ophrectomy was also done due to their adherence. Hemostasis was secured. The patient and baby progressed well and were discharged on the seventh postoperative day

  6. Radiography of the abdominal cavity

    Radiography is a very important part of the diagnostic procedure in many small animal diseases. Technically perfect X-rays are essential for the exact diagnosis. The general appearance of the abdominal cavity should be evaluated at first, e.g. the overall contrast and the definition of the visualized organs. Then particular attention should be paid, if there is any peritoneal effusion or free air in the peritoneal cavity. Subsequently each radiographically visible organ has to be evaluated for its position, size, shape and radiographic density

  7. Screening for Abdominal Aortic Aneurysm

    2014-01-01

    Abdominal Aortic Aneurysm (AAA) is a common disease with a prevalence of 1.5-2.0% in 65-year old men in Sweden. The risk of having AAA is increased with smoking, high age, family history of AAA and cardiovascular disease. Women have a lower prevalence (0.5%) and develop AAA later in life. An AAA seldom gives any symptom prior to rupture. Untreated rupture is associated with 100% mortality, while surgically treated rupture is associated with 25-70% mortality. Prophylactic sur...

  8. Abdominal manifestations of autoimmune disorders

    Full text: Immunoglobulin G4-related disease was recognized as a systemic disease since various extrapancreatic lesions were observed in patients with autoimmune pancreatitis (AIP). 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

    2009-01-01

    Abstract: During insufflation of the abdomen to create a pneumoperitoneum for laparoscopy, both intra abdominal pressure and insufflated volume can be measured and are used to calculate the abdominal pressure-volume relationship. First, an accurate, linear relationship was identified using a mathematical model with an elastance, E, or its reciprocal the compliance C and with a pressure at zero volume, PV0. This function was stable and could be used to describe the abdominal characteristics of...

  12. The actual goals of geoethics

    Nemec, Vaclav

    2014-05-01

    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

    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.

    Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". 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.

    Díaz, Elías

    2002-06-01

    Full Text Available As against bad «reasons of state», both past and present, a number of good reasons of state are put forward here as sound demands for times to come. 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.

  17. Abdominal ultrasound in AIDS patients

    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.

  18. The Neonate with Abdominal Mass

    M. Bajoghli

    2008-01-01

    Full Text Available Neonatal abdominal masses have broad spectrum of pathology, ranging from small lesions found incidentally to large masses occupying the entire of peritoneal cavity. These tumors are benign to malignant, and from unilocular cysts to complex solid lesions. Many of these lesions identified and will treat before delivery. Others are discovered during routine examination. These lesions may be life threatening, or cause persistent morbidity. Some of these have no sequel."nDiagnosis began with history. Characteristic of the mass which must be note include location, size, shape, texture, mobility and tenderness. Other findings should be in mind to find out nature of mass, for example hypoplasia of chest wall with oligohydramnios due to GU tract obstruction (potter sequwnce, a bulging hymen due to hydrometrocolpus, skin metastasis due to neuroblastoma. Radiography is the next step that shows organomegaly and calcification. Next step is US which is an excellent screening tool. CT and MRI are occasionally indicated."nThe purpose of this presentation is to review the diagnosis of abdominal masses in neonates.

  19. Percutaneous drainage of abdominal abcess

    Men, Sueleyman E-mail: suleyman.men@deu.edu.tr; Akhan, Okan; Koeroglu, Mert

    2002-09-01

    The mortality in undrained abdominal abscesses is high with a mortality rate ranging between 45 and 100%. The outcome in abdominal abscesses, however, has improved due to advances in image guided percutaneous interventional techniques. The main indications for the catheter drainage include treatment or palliation of sepsis associated with an infected fluid collection, and alleviation of the symptoms that may be caused by fluid collections by virtue of their size, like pancreatic pseudocele or lymphocele. The single liver abscesses may be drained with ultrasound guidance only, whereas the multiple abscesses usually require computed tomography (CT) guidance and placement of multiple catheters. The pancreatic abscesses are generally drained routinely and urgently. Non-infected pancreatic pseudocysts may be simply observed unless they are symptomatic or cause problems such as pain or obstruction of the biliary or the gastrointestinal tract. Percutaneous routes that have been described to drain pelvic abscesses include transrectal or transvaginal approach with sonographic guidance, a transgluteal, paracoccygeal-infragluteal, or perineal approach through the greater sciatic foramen with CT guidance. Both the renal and the perirenal abscesses are amenable to percutaneous drainage. Percutaneous drainage provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses as well.

  5. Hypoxia inhibits abdominal expiratory nerve activity.

    Fregosi, R F; Knuth, S L; Ward, D K; Bartlett, D

    1987-07-01

    Our purpose was to examine the influence of steady-state changes in chemical stimuli, as well as discrete peripheral chemoreceptor stimulation, on abdominal expiratory motor activity. In decerebrate, paralyzed, vagotomized, and ventilated cats that had bilateral pneumothoraces, we recorded efferent activity from a phrenic nerve and from an abdominal nerve (cranial iliohypogastric nerve, L1). All cats showed phasic expiratory abdominal nerve discharge at normocapnia [end-tidal PCO2 38 +/- 2 Torr], but small doses (2-6 mg/kg) of pentobarbital sodium markedly depressed this activity. Hyperoxic hypercapnia consistently enhanced abdominal expiratory activity and shortened the burst duration. Isocapnic hypoxia caused inhibition of abdominal nerve discharge in 11 of 13 cats. Carotid sinus nerve denervation (3 cats) exacerbated the hypoxic depression of abdominal nerve activity and depressed phrenic motor output. Stimulation of peripheral chemoreceptors with NaCN increased abdominal nerve discharge in 7 of 10 cats, although 2 cats exhibited marked inhibition. Four cats with intact neuraxis, but anesthetized with ketamine, yielded qualitatively similar results. We conclude that when cats are subjected to steady-state chemical stimuli in isolation (no interference from proprioceptive inputs), hypercapnia potentiates, but hypoxia attenuates, abdominal expiratory nerve activity. Mechanisms to explain the selective inhibition of expiratory motor activity by hypoxia are proposed, and physiological implications are discussed. PMID:3624126

    This review deals with the in vivo magnetic resonance imaging (MRI) appearance of the human fetal abdomen. Imaging findings are correlated with current knowledge of human fetal anatomy and physiology, which are crucial to understand and interpret fetal abdominal MRI scans. 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

  15. Abdominal Burkitt lymphoma in children : CT finding

    To evaluate the CT findings of Burkitt's lymphoma involving the abdomen in children We retrospectively analyzed the abdominal CT of ten children who presented with abdominal symptom. They were confirmed by operation in two cases and by fine needle aspiration biopsy in eight to be suffering from Burkitt's lymphoma. We also abdominal ultrasonography(USG)(n=10) and carried out small bowel follow-through examination(SBS)(n=5). Analyses focused on features of the abdominal mass : bowel wall thickening, ascites, lymphadenopathy, and the involvement of intra-abdominal solid organ. Abdominal CT at the time of presentation showed a huge conglomerated mass encasing segments of small bowel and also peripherally displacing bowel loops(n=9), bowel wall thickening(n=10), and ascites(n=10). In three of these cases, we were able to see tumor necrosis and cavity formation. Extensive infiltration into mesenteric fat and obliteration of tissue plane made it impossible to identify on CT the margin of the tumor and the presence of mesenteric lymphadenopathy. In four patients, sonography showed enlarged mesenteric lymph nodes(15-20mm), and in three, retroperitoneal lymph nodes(5mm, 10mm, 12mm in long dimension) were detected on CT and USG. Abdominal CT can reveal the characteristic imaging features of Burkitt's lymphoma in children. These are a huge conglomerate mass with or without cavity formation, that encases the small bowel and infiltrates the mesentery, ascites, and the relatively spared retroperitoneal lymph nodes

    1996-10-01

    To evaluate the CT findings of Burkitt's lymphoma involving the abdomen in children We retrospectively analyzed the abdominal CT of ten children who presented with abdominal symptom. They were confirmed by operation in two cases and by fine needle aspiration biopsy in eight to be suffering from Burkitt's lymphoma. We also abdominal ultrasonography(USG)(n=10) and carried out small bowel follow-through examination(SBS)(n=5). Analyses focused on features of the abdominal mass : bowel wall thickening, ascites, lymphadenopathy, and the involvement of intra-abdominal solid organ. Abdominal CT at the time of presentation showed a huge conglomerated mass encasing segments of small bowel and also peripherally displacing bowel loops(n=9), bowel wall thickening(n=10), and ascites(n=10). In three of these cases, we were able to see tumor necrosis and cavity formation. Extensive infiltration into mesenteric fat and obliteration of tissue plane made it impossible to identify on CT the margin of the tumor and the presence of mesenteric lymphadenopathy. In four patients, sonography showed enlarged mesenteric lymph nodes(15-20mm), and in three, retroperitoneal lymph nodes(5mm, 10mm, 12mm in long dimension) were detected on CT and USG. Abdominal CT can reveal the characteristic imaging features of Burkitt's lymphoma in children. These are a huge conglomerate mass with or without cavity formation, that encases the small bowel and infiltrates the mesentery, ascites, and the relatively spared retroperitoneal lymph nodes.

  17. Abdominal ultrasonographic findings of Yersiniosis in children

    To review abdominal ultrasonography in Yersinia Pseudotuberculosis(YP) infection. From June 1993 through June 1994, abdominal ultrasonograms were reviewed in 36 patients with YP infection. The age of patients was from 4 to 14 years. A diagnosis of YP infection was made on the basis of isolation of YP from stool (n=15/36, 41.7%) and by documenting at least a minimum agglutination antibody titer of 1;160 or greater (n=34/36, 94.4%). Abdominal US findings were identified in 33/36 (91.7%) of patients with YP infection. US abnormalities included right lower quadrant abdominal lymphadenopathy in 28/36 (77.8%) of cases: increased bilateral renal cortical echogenecity with renal enlargement, 11/36 (30.6%) of cases:hepatosplenomegaly, 6/36 (16.7%) of cases: bowel wall thickening in termnal ileum and cecum, 4/36 (11.1%) of cases:and ascites, 2/36 (5.5%) of cases. Three patients revealed no abdominal sonographic finding. We conclude that abdominal US can help in the diagnosis of YP infection when US demonstrates multiple right lower quadrant abdominal lymphadenopathy, increased renal cortical echogenecity with renal enlargement, hepatosplenomegaly, intestinal wall thickening or ascites

  18. Radiologic findings of abdominal wall endometriosis

    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

  20. Abdominal fat reducing outcome of exercise training: fat burning or hydrocarbon source redistribution?

    Kuo, Chia-Hua; Harris, M Brennan

    2016-07-01

    Fat burning, defined by fatty acid oxidation into carbon dioxide, is the most described hypothesis to explain the actual abdominal fat reducing outcome of exercise training. This hypothesis is strengthened by evidence of increased whole-body lipolysis during exercise. As a result, aerobic training is widely recommended for obesity management. This intuition raises several paradoxes: first, both aerobic and resistance exercise training do not actually elevate 24 h fat oxidation, according to data from chamber-based indirect calorimetry. Second, anaerobic high-intensity intermittent training produces greater abdominal fat reduction than continuous aerobic training at similar amounts of energy expenditure. Third, significant body fat reduction in athletes occurs when oxygen supply decreases to inhibit fat burning during altitude-induced hypoxia exposure at the same training volume. Lack of oxygen increases post-meal blood distribution to human skeletal muscle, suggesting that shifting the postprandial hydrocarbons towards skeletal muscle away from adipose tissue might be more important than fat burning in decreasing abdominal fat. Creating a negative energy balance in fat cells due to competition of skeletal muscle for circulating hydrocarbon sources may be a better model to explain the abdominal fat reducing outcome of exercise than the fat-burning model.

    We report a case of combined subcutaneous, intrathoracic, and abdominal splenosis who presented with attacks of flushing, tachycardia and vague abdominal pain. The patient's past medical history included a splenectomy due to abdominal trauma and years later, a lung lobectomy due to recurrent pneumonia. An enhancing solid mass adjacent to the upper pole of the left kidney and nodular pleural based lesions in the left hemi-thorax along with nodular lesions in subcutaneous tissue of the left chest wall suggested possible adrenal malignancy with multiple metastases. Histopathologic examination demonstrated benign lesions of ectopic splenic tissue. PMID:20804314

    A 73-year-old man was transferred for treatment of abdominal aortic aneurysm. He had no history of abdominal surgeries. Grafting between the infra-renal abdominal aorta and the bilateral common iliac arteries was performed. Proximal and distal cross clamps were applied for grafting. He developed chylous ascites on the 5th post-operative day, 2 days after initiation of oral intake. Fortunately, he responded to treatment with total parenteral hyper-alimentation for 10 days, followed by a low-fat diet. There was no recurrence of ascites. PMID:27087873

  7. Staging of pediatric abdominal malignancies

    The scope of this review is the role of CT in the staging of childhood solid abdominal malignancies. Owing to the limitations of space, only the commonest lesions will be discussed in detail: Wilms' tumor, neuroblastoma, and liver tumors. The TNM staging system has been utilized throughout this monograph. It will not be used in this chapter, however, since in this country different staging systems individualized to each pediatric tumor have been developed. These staging systems take into account the different biology of each tumor and have clear correlations with prognosis and therapeutic programs. The discussion centers almost exclusively on the role of CT in the staging and management of neoplastic processes in children. The information required for staging can sometimes be obtained by other imaging modalities (i.e., ultrasound, excretory urography, etc.) The choice of modality will be strongly influenced by techniques and expertise available as well as by the bias of the institution. An additional factor to be taken into consideration will be the economic factor. Prospective reimbursement will strongly encourage the use of tests that are cost-effective and clinically efficacious

  8. Extraction of fetal electrocardiogram (ECG) by extended state Kalman filtering and adaptive neuro-fuzzy inference system (ANFIS) based on single channel abdominal recording

    D Panigrahy; P K Sahu

    2015-06-01

    Fetal electrocardiogram (ECG) gives information about the health status of fetus and so, an early diagnosis of any cardiac defect before delivery increases the effectiveness of appropriate treatment. In this paper, authors investigate the use of adaptive neuro-fuzzy inference system (ANFIS) with extended Kalman filter for fetal ECG extraction from one ECG signal recorded at the abdominal areas of the mother’s skin. The abdominal ECG is considered to be composite as it contains both mother’s and fetus’ ECG signals. We use extended Kalman filter framework to estimate the maternal component from abdominal ECG. The maternal component in the abdominal ECG signal is a nonlinear transformed version of maternal ECG. ANFIS network has been used to identify this nonlinear relationship, and to align the estimated maternal ECG signal with the maternal component in the abdominal ECG signal. Thus, we extract the fetal ECG component by subtracting the aligned version of the estimated maternal ECG from the abdominal signal. Our results demonstrate the effectiveness of the proposed technique in extracting the fetal ECG component from abdominal signal at different noise levels. The proposed technique is also validated on the extraction of fetal ECG from both actual abdominal recordings and synthetic abdominal recording.

  10. Actual Causation in CP-logic

    Vennekens, Joost

    2011-01-01

    Given a causal model of some domain and a particular story that has taken place in this domain, the problem of actual causation is deciding which of the possible causes for some effect actually caused it. One of the most influential approaches to this problem has been developed by Halpern and Pearl in the context of structural models. In this paper, I argue that this is actually not the best setting for studying this problem. As an alternative, I offer the probabilistic logic programming language of CP-logic. Unlike structural models, CP-logic incorporates the deviant/default distinction that is generally considered an important aspect of actual causation, and it has an explicitly dynamic semantics, which helps to formalize the stories that serve as input to an actual causation problem.

  16. Adhesive intestinal obstruction following blunt abdominal trauma

    Advances in diagnosis and management of multiple trauma patients have lead to adopting a conservative approach for most patients with blunt abdominal trauma. Intestinal obstruction is a rare complication for this approach. Herein, we report a 37-year-old male, who did not have an abdominal operation, and who developed adhesive intestinal obstruction 7 weeks following blunt abdominal trauma. We detected no signs of peritonitis or intra-abdominal bleeding clinically or radiologically on admission. We initially treated the intestinal obstruction conservatively, but the obstruction did not resolve. Finally, we performed laparotomy, which showed that the small bowel was matted together by thick fibrous layers of adhesions. We performed adhesiolysis, and the patient was discharged home 3 weeks later. Histopathological findings of the fibrous layer were consistent with repair due to previous trauma and hemorrhage. We review the literature of this rare condition. (author)

  3. [Intestinal occlusion and abdominal compartment syndrome (ACS)].

    Stagnitti, Franco

    2009-01-01

    Intestinal occlusion is defined as an independent predictive factor of intra-abdominal hypertension (IAH) which represents an independent predictor of mortality. Baggot in 1951 classified patients operated with intestinal occlusion as being at risk for IAH ("abdominal blow-out"), recommending them for open abdomen surgery proposed by Ogilvie. Abdominal surgery provokes IAH in 44.7% of cases with mortality which, in emergency, triples with respect to elective surgery (21.9% vs 6.8%). In particular, IAH is present in 61.2% of ileus and bowel distension and is responsible for 52% of mortality (54.8% in cases with intra-abdominal infection). These patients present with an increasing intra-abdominal pressure (IAP) which, over 20-25 mmHg, triggers an Abdominal Compartment Syndrome (ACS) with altered functions in some organs arriving at Multiple Organ Dysfunction Syndrome (MODS). The intestine normally covers 58% of abdominal volume but when there is ileus distension, intestinal pneumatosis develops (third space) which can occupy up to 90% of the entire cavity. At this moment, Gastro Intestinal Failure (GIF) can appear, which is a specific independent risk factor of mortality, motor of "Organ Failure". The pathophysiological evolution has many factors in 45% of cases: intestinal pneumatosis is associated with mucosal and serous edema, capillary leakage with an increase in extra-cellular volume and peritoneal fluid collections (fourth space). The successive loss of the mucous barrier permits a bacterial translocation which includes bacteria, toxins, pro-inflammatory factors and oxygen free radicals facilitating the passage from an intra-abdominal to inter-systemic vicious cyrcle. IAH provokes the raising of the diaphragm, and vascular and visceral compressions which induce hypertension in the various spaces with compartmental characteristics. These trigger hypertension in the renal, hepatic, pelvic, thoracic, cardiac, intracranial, orbital and lower extremity areas, giving

    A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child. PMID:10499389

Diagnostic laparoscopy revealed a twisted small intra-abdominal testis in which the spermatic cord twisted 3 times over a band attached to the internal ring. The cord was long enough to bring the small testis into the scrotal sac. This case highlights the pole of laparoscopy in the management of impalpable testes.

  11. Diagnosis and treatment of expanding haematoma of the lateral abdominal wall after blunt abdominal trauma

    We report a rare case of an expanding post-traumatic lateral abdominal wall haematoma. A superselective arteriogram of the deep circumflex iliac artery showed extravasation from the ascending branch, urging emergency therapy. Microcoil and Gelfoam embolisation was successfully performed. Haematomas of the abdominal wall can be divided in the common rectus sheath haematomas and the rare haematomas of the lateral abdominal wall. Differentiating both entities is essential, since there is a strong difference in their vascular supply. The typical vascular supply of the lateral abdominal wall is discussed, with emphasis on the ascending branch of the deep circumflex iliac artery. (orig.)

  14. Abdominal tuberculosis: clinical presentation and outcome

    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.

  15. Effect of rectal distension on abdominal girth.

    Marino, B; Ogliari, C; Basilisco, G

    2004-08-01

    It has been postulated that a viscerosomatic reflex activated by gut distension and inhibiting abdominal wall muscle tone may be one of the mechanisms underlying functional abdominal distension. Any demonstration of such a reflex has to take into account the fact that gut distension may increase abdominal girth as a result of volume displacement. As biomechanical and sensory rectal responses vary at different rates of rectal distension, we hypothesized that different rates of rectal distension might reveal different changes in abdominal girth. Abdominal girth was continuously recorded in 14 healthy subjects using a previously validated extensometer. The rectal distensions were made in a randomized order at rates of 100 mL min(-1) or 10 mL min(-1) up to 150 mL, and sham distensions were used as controls. An increase in abdominal girth was observed at the end of both distensions (P

    Full Text Available Objective: To identify the association of dietary, socioeconomic factors, sedentary behaviors and maternal nutritional status with abdominal obesity in children. Methods: 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 3-10 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. Results: 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. Conclusions: 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.

  17. Subjective biological self and self-actualization.

    Sumerlin, J R; Berretta, S A; Privette, G; Bundrick, C M

    1994-12-01

    Ginsburg, Rogers, and Maslow, humanistic theorists, have maintained that the self is an emergent characteristic of one's biological makeup. The relationship between physical self-efficacy as an appraisal of subjective biology and self-actualization was examined in a sample of 160 black and white participants. An r of .46 supports the association of subjective biology and self-actualization. Whereas there were no gender or racial differences in scores on self-actualization, men scored higher on physical self-efficacy and subscales of perceived physical ability and perceived self-presentation confidence.

    Full Text Available En el presente artículo se ofrece una caracterización breve de los territorios y condiciones en que viven los gru - pos indígenas que habitan en el estado de Sonora, a partir de su historia. Además, se plasma su situación actual en indica - dores territoriales, demográficos, actividades económicas, educación, vivienda, salud y rezago social. En Sonora hay nueve grupos étnicos, integrados por alrededor de 138 mil personas, lo que representa 5.2 por ciento de la población total de la entidad. En conjunto, poseen 5.8 por ciento de la superficie estatal, aunque en áreas desérticas, montañosas, de difícil acceso y, en algunos casos, la comparten con gente no indígena. Ochenta por ciento de estos grupos vive en comunidades rurales, por lo general alejadas de los centros urbanos, con acceso insuficiente a la educación y a los ser - vicios médicos, con fuentes de trabajo de bajo perfil y paga, viviendas pequeñas con pocos bienes y carentes de electricidad, drenaje y agua potable de calidad. Los indicadores analizados confirman el estado de marginación, vulnerabilidad y fragilidad de este sector de la población, y marcan la necesidad urgente de apoyo real de parte del Estado.

    To assess the extent of extra imaging beyond the prescribed anatomical margins for chest and abdominal CT and to determine associated extra patient and organ dose estimates. For 167 consecutive patients undergoing routine chest and/or abdominal examination with 128-slice CT, extra imaging length was evaluated on coronal images. Effective and organ doses (thyroid, liver, breasts, testes) were calculated. Paired t-test was applied to evaluate statistically significant differences between prescribed and actual imaging length, and associated doses. 133 (80%) examinations had extra coverage (mean 4.6 cm, range 1-19.5 cm). Significantly higher (P < 0.05) effective doses for chest CT (mean 4.8 mSv vs 4.2 mSv for actual vs prescribed volume of interest), abdominal CT (8.4 mSv vs 7.9 mSv) or thorax-abdominal CT (12.8 mSv vs 11.9 mSv) were found. A significantly higher (P < 0.001) organ dose was estimated for thyroid (extra dose 99% corresponding to 5.1 mSv), liver (56%, 2.2 mSv), testes (115%, 7.6 mSv), and breasts (163%, 1.5 mSv). Imaging beyond anatomical limits during routine chest and abdominal CT results in higher organ and effective doses. Continuous training of the technologists remains important. Physicians and technologists must be kept aware of the additional dose associated with extra imaging. (orig.)

  3. The therapeutic impact of abdominal ultrasound in patients with acute abdominal symptoms

    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)

    2008-01-01

    We report a case of abdominal eventration associated with cystic fibrosis, diagnosed by mid-trimester ultrasonography. The defect concerned the abdominal muscles and their aponevrotic sheath, but respected the skin. There was no associated malformation. The outcome was favorable after surgery, and the infant is well at the age of 6 months. PMID:18046068

  5. CT diagnosis of abdominal ectopic pheochromocytoma

    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)

  6. Abdominal tuberculosis, clinical-radiological revision

    We retrospectively evaluated the clinical charts and diagnostic images of hospitalised patients with histological or bacteriologic demonstration of abdominal tuberculosis (TB) including those with probable abdominal TB, who had pulmonary TB and radiologic findings highly suggestive of abdominal TB with favourable response to treatment. Cases with genitourinary TB were excluded. We found 24 patients with an average age of 25 yrs. In some cases this entity was not suspected on the imaging studies, and diagnosis was made on surgery. The most frequent symptoms were: abdominal pain, diarrhoea, fever, vomiting, weight loss and abdominal mass. Active pulmonary TB was demonstrated on 8 cases (33%) Peritoneal presentation was the most frequent (54%) with septated or simple ascites, cystic ascites or pseudocysts within bowel loops. Mesenteric involvement (21 %) showed adenopathy or masses identified with CT. Intestinal forms (17%) showed pseudo-polyps on terminal ileum and ulcers on ileum, cecum and colon. We found one case with diffuse ulcerative involvement of the colon. Two cases showed hepatic involvement, one with an abscess and a tuberculosis Cole cystitis, with pyloric syndrome due to fibrosis

  7. Paediatric emergencies: non-traumatic abdominal emergencies

    Presentation with acute abdominal pain or abdominal symptopathology is a very common cause of presentation of children to hospital. The causes are dependent in part on the age of the child, in part on the presence of previous surgery, and can be divided into those that relate to congenital abnormalities at whatever age they present, acquired disease and infection. Children, particularly young children are often poor historians, and therefore the clinical examination and the laboratory investigations are important in helping to come to a diagnosis. Primary imaging of abdominal emergencies in childhood is a radiograph of the abdomen, followed by ultrasound. Further imaging depends on the results of these studies. An ordered review of the abdomen radiograph is important if the salient features on X-ray are not to be missed. Practitioners should be competent with abdominal ultrasound in children and know where to seek the causes of disease, as these are different from those that are obtained in many instances in adults. Familiarity with the likely causes is important. The three commonest causes of acute abdominal pain in childhood are, in young infants, intussusception, appendicitis and mesenteric adenitis. In older children, inflammatory bowel disease and ovarian pathology are also included. This article details the approach to imaging and the salient features of some of the conditions. (orig.)

  11. Thoracic and abdominal blastomycosis in a horse.

    Toribio, R E; Kohn, C W; Lawrence, A E; Hardy, J; Hutt, J A

    1999-05-01

    A 5-year-old Quarter Horse mare was examined because of lethargy, fever, and weight loss of 1 month's duration. Thoracic auscultation revealed decreased lung sounds cranioventrally. Thoracic ultrasonography revealed bilateral anechoic areas with hyperechoic strands, consistent with pleural effusion and fibrin tags. A large amount of free fluid was evident during abdominal ultrasonography. Abnormalities included anemia, hyperproteinemia, hyperglobulinemia, hyperfibrinogenemia, and hypoalbuminemia. Thoracic radiography revealed alveolar infiltrates in the cranial and caudoventral lung fields. A cavitary mass, consistent with an abscess, could be seen caudodorsal to the crura of the diaphragm. Ultrasonographic evaluation of this area revealed a hypoechoic mass with septations. Bilateral thoracocentesis was performed. Bacterial culture of the pleural fluid did not yield growth, but Blastomyces dermatitidis was isolated from pleural fluid, abdominal fluid, and an aspirate of the abscess. The mare was euthanatized, and a diagnosis of thoracic and abdominal blastomycosis was confirmed at necropsy. PMID:10319179

  12. [Pediatric Abdominal Pain – Harmless or Harmful?].

    Furlano, Raoul Ivano

    2016-04-27

    Abdominal pain is a very common pediatric complaint. In the majority of cases there is no life-threatening pathology behind this symptom, but a functional disease. However, all-day activities of children and adolescents are often limited, frequent absences from school, and general physician/ pediatrician office visits with often unnecessary diagnostic and therapies are registered. Once an organic etiology of the abdominal pain is excluded by a thoroughly medical history taking and physical examination, the first steps for a successful alleviation of the pain is the reassurance of the patients and their family that there is no life-threatening pathology. There is evidence that cognitive-behavioral therapy may be useful in improving pain and disability outcome in the short term. There is no evidence for pharmacological, dietetic, or complementary intervention in the treatment of chronic functional abdominal pain. PMID:27120211

  13. Indium 111 leucocyte scintigraphy in abdominal sepsis

    We have studied the clinical utility of indium 111 autologous leucocyte scintigraphy retrospectively in 45 patients presenting with suspected intra-abdominal sepsis. The sensitivity was 95% (21/22) and the specificity was 91% (21/23). Some 34 of the studies (17 positive and 17 negative) were considered helpful in furthering patient management (76%) and 8, unhelpful (18%). In 3, the study results were misleading and led to inappropriate treatment. Indium 111 scintigraphy, whether positive or negative, provides information in patients with suspected intra-abdominal sepsis upon which therapeutic decisions can be based. (orig.)

  14. Aggressive malignant abdominal mesothelioma: Clinical report

    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

    Neurofibromatosis type-1 (NF-1), also known as von Recklinghausendisease, is a common autosomal dominant condition with an approximateincidence of one per 300 births. NF1 involves multiple systems of the body.Abdominal involvement occurs in the form of neurofibroma and tumor growth inthe liver, mesentery, retroperitoneum, gastric and bowel. Gastrointestinalneoplasms have a reported occurrence of 2-25%. Two cases are reported hereinas well as a review of the literature of the intra-abdominal manifestationsof NF1, including a discussion on the radiological appearance and diagnosis.The article provides an insight into the intriguing variety of clinicalproblems that such patients may present.

We also describe imaging features and clues to the diagnosis. (orig.)

  17. Upper abdominal trauma in children: imaging evaluation

    One hundred consecutive children with serious blunt upper-abdominal injury were evaluated prospectively to assess the accuracy and usefulness of emergency computed tomography (CT) compared with liver-spleen scintigraphy and sonography. Ninety-five hemodynamically stable patients were imaged. The results of this 20-month study indicated that CT has fewer false negatives and false positives than scintigraphy or sonography, that CT is useful in abdominal trauma, and that CT provides the most information of any single diagnostic imaging test commonly available

    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.

    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.)

  12. Abdominal cavity exploration with kinetic scintimaging

    Nuclear medicine procedures are being utilized in an increasing variety and number of intra-abdominal clinical problems. These non-invasive intra-abdominal exploratory scintimaging procedures are often dynamic or kinetic in nature, i.e. revealing primarily functional information even to the point of employing adjunctive drugs and multiple simultaneous radiotracers. The advent of correlative non-invasive diagnostic imaging modalities has thus far largely complemented abdominal nuclear medicine procedures. The luminal gastro-intestinal tract has yielded to investigation with radiotracers with procedures now widely employed to study gastric function, gastro-oesophagal reflux and intestinal bleeding. The role of hepatic and splenic reticuloendethelial compartment imaging has been strengthened by increased dependability, and remains as the first line screening test for a variety of suspected intrahepatic lesions, especially neoplasia. The recent introduction of improved hepatobiliary radiotracers, mostly iminodiacetic acid derivatives, has considerably expanded the scope of diagnostic investigations of the liver, especially in problems of jaundice and acute cholecystitis. Pancreatic imaging continues to be a disappointment and at best is only adjunctive to correlative imaging procedures. Some hope may be seen in the recent reports of successful pancreatic imaging with positron emission tomography utilizing labelled amino-acid derivatives. Diffuse abdominal processes, especially abcesses and suspected infection, have been efficaciously approached with 67Ga citrate and also, more recently, 111-In-labelled leucocytes. Many of these advances and applications have also been readily applicable to pediatric problems. (author)

  13. Intra-abdominal tumors in children

    Objective: The objective of the present study was to observe the histopathological pattern of intra-abdominal tumors in children less than 16 years. Place and Duration of Study: The study was carried out at the Department of Histopathology, Children's Hospital and the Institute of Child Health and King Edward Medical College, Lahore, over a period of 5 years, from January 1997 to December 2002. Subjects and Methods: The histopathological and demographic data of 264 intra-abdominal tumors of both the sexes under 16 years of age was collected and analyzed to determine the various morphological types of intra- abdominal tumors in relation to age and sex. Results: Neuroblastoma was the most common tumor constituting 29.6% of all cases, followed by Wilms' tumor (25.1%). Others were non-Hodgkins Iymphomas (15.5%), germ cell tumors and hepatoblastoma (9%) each, rhabdomyosarcoma (4.4%), hepatocellular carcinoma (1.4%) and miscellaneous (6%). Majority of the patients (77.2%) were under 5 years of age. The male to female ratio was 1.1 :0.9. Conclusion: Intra-abdominal tumors are more common in males. Most of the tumors were noted in children less than 5 years of age. (author)

    Bodoky, A; Heberer, M; Iwatschenko, P; Harder, F

    1985-10-01

    Needle catheter jejunostomy is used to a varying extent today. Therefore, the need for nutritional support was evaluated following elective abdominal surgery and compared to experiences with postoperative enteral feeding. Oesophagectomy, total gastrectomy and the Whipple procedure were identified as good indications for catheter jejunostomy, whereas with other types of operation an individual decision is required.

  15. CT features of abdominal plasma cell neoplasms

    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.)

  20. Whiteheadian Actual Entitities and String Theory

    Bracken, Joseph A.

    2012-06-01

    In the philosophy of Alfred North Whitehead, the ultimate units of reality are actual entities, momentary self-constituting subjects of experience which are too small to be sensibly perceived. Their combination into "societies" with a "common element of form" produces the organisms and inanimate things of ordinary sense experience. According to the proponents of string theory, tiny vibrating strings are the ultimate constituents of physical reality which in harmonious combination yield perceptible entities at the macroscopic level of physical reality. Given that the number of Whiteheadian actual entities and of individual strings within string theory are beyond reckoning at any given moment, could they be two ways to describe the same non-verifiable foundational reality? For example, if one could establish that the "superject" or objective pattern of self- constitution of an actual entity vibrates at a specific frequency, its affinity with the individual strings of string theory would be striking. Likewise, if one were to claim that the size and complexity of Whiteheadian 'societies" require different space-time parameters for the dynamic interrelationship of constituent actual entities, would that at least partially account for the assumption of 10 or even 26 instead of just 3 dimensions within string theory? The overall conclusion of this article is that, if a suitably revised understanding of Whiteheadian metaphysics were seen as compatible with the philosophical implications of string theory, their combination into a single world view would strengthen the plausibility of both schemes taken separately. Key words: actual entities, subject/superjects, vibrating strings, structured fields of activity, multi-dimensional physical reality.

  1. Actual imaging time in fetal MRI

    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.

  4. Evaluation of abdominal CT in the initial treatment of abdominal trauma

    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.

    2012-12-15

    Intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) have shown clinical relevance in monitoring critically ill human beings submitted to abdominal surgery. Only a few studies have been performed in veterinary medicine. The aim of this study was to assess how pregnancy and abdominal surgery may affect IAP and APP in healthy cats. For this purpose, pregnant (n=10) and non-pregnant (n=11) queens undergoing elective spaying, and tomcats (n=20, used as controls) presented for neutering by scrotal orchidectomy were included in the study. IAP, mean arterial blood pressure (MAP), APP, heart rate and rectal temperature (RT) were determined before, immediately after, and four hours after surgery. IAP increased significantly immediately after abdominal surgery in both female groups when compared with baseline (P<0.05) and male (P<0.05) values, and returned to initial perioperative readings four hours after surgery. Tomcats and pregnant females (P<0.05) showed an increase in MAP and APP immediately after surgery decreasing back to initial perioperative values four hours later. A significant decrease in RT was appreciated immediately after laparotomy in both pregnant and non-pregnant queens. IAP was affected by abdominal surgery in this study, due likely to factors, such as postoperative pain and hypothermia. Pregnancy did not seem to affect IAP in this population of cats, possibly due to subjects being in early stages of pregnancy. PMID:23118052

    Full Text Available The record of the South American fossil Squamata extends from the Late Cretaceous to the Holocene. 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.

    Full Text Available La infección por el virus del papiloma humano (VPH es una enfermedad de transmisión sexual común. Alrededor del mundo millones de personas están infectadas y el resto de la población en general tiene un riesgo de contraer la infección superior al 50%. El virus se asocia aproximadamente a un 100% de los casos de cáncer cervical; a un 100% de las neoplasias cervicales intraepiteliales grados 1, 2, 3; a un 40% de los casos de cáncer de vulva, vagina y pene, 100% de las verrugas genitales; a un 100% de las papilomatosis respiratorias recurrentes; a un 90% del cáncer anal y a un 12% del cáncer de cabeza y cuello, predominantemente en orofaringe y amígdala. Actualmente, el uso de dos vacunas está aprobado en diversos países: Gardasil® y Cervarix®. Ambas están compuestas por proteínas L1 de VPH, en forma de partículas no infecciosas similares al virus (VLPs producidas por tecnología de ADN recombinante, adsorbidas en adyuvantes que contienen aluminio. La eficacia hallada en diversos estudios en sujetos no expuestos previamente al virus se encuentran en el rango del 98.8% al 100.0% para la prevención de neoplasias cervicales, vulvares y vaginales intraepiteliales, grados 2 y 3, relacionados con el VPH-16/18, además de los adenocarcinomas in situ y verrugas genitales causadas por VPH- 16/18/6/11 en el caso de Gardasil® y una eficacia del 100% en el caso de Cervarix® para la prevención de neoplasias cervicales grado 2 y 3 relacionados con el VPH-16/18. La eficacia de ambas se mantiene alrededor de los 5 años. Hasta el momento no se le ha atribuido a la vacuna ningún efecto terapéutico, solo se administra con fines profilácticos, sin embargo, esta no debe ser considerada como un sustituto de las pruebas de tamizaje para la prevención del cáncer cervical.Genital human papillomavirus (HPV is one of the most common sexually transmitted infections worldwide. Millions of persons are now infected and the lifetime risk of HPV infection exceeds 50%. HPV is approximately 100% related to the total cases of cervical cancer, 100% of cervical intraepithelial neoplasias grade 1, 2, and 3; 40% of vulva, vagina and penile cancer, 100% of genital warts, 100% of recurrent respiratory papillomatosis and 12% of head and neck cancer. Licensed vaccines, Gardasil® and Cervarix®, are composed of a noninfectious mixture of HPV type-specific virus-like particles prepared from the L1 proteins produced by recombinant DNA technology and adsorbed in a aluminum-containing adjuvant. Data from several studies of both vaccines reported a range of efficacy of 98,9 % to 100.0% for the prevention of cervical, vulvar and vaginal intraepithelial neoplasias degrees 2 and 3, and therefore, cervical, vulvar and vaginal cancer related to the VPH-16/18; in addition to in situ adenocarcinomas and genital warts caused by VPH-16/18/6/11. The effectiveness for both vaccines is maintained for at least 5 years. At the moment no therapeutic effect has been attributed and the vaccine use is prophylactic, nevertheless, vaccination should not be considered as a substitute for cervical cancer screening.

    2012-07-01

    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.

  14. Estado actual del conocimiento de la biología de grupos aborígenes de la Argentina

    Carnese, Francisco R.

    2003-01-01

    Full Text Available Desde el año 1927 y hasta mediados de la década de 1980, los estudios genéticos poblacionales en aborígenes argentinos se circunscribieron principalmente al análisis y distribución de los grupos sanguíneos. Hacia fines de esa década comienzan a emplearse otros marcadores genéticos para la caracterización biológica de esos grupos humanos: enzimas eritrocitarias, proteinas séricas, sistemas HLA, Gm/Km, ADNn y ADNmt. Parte de esa información se empleo en el análisis de la diversidad genética de poblaciones del Chaco (wichi, toba y chorote y de la Patagonia (mapuche y tehuelche a diferentes niveles jerárquicos: proteico, nuclear y mitocondrial. La variabilidad genética intrapoblacional varió del 91% al 99%, mientras que el porcentaje de diferenciación genética interpoblacional (Gst' se incrementó desde el nivel proteico al molecular (proteico: Gst'=3.6%; ADNn: Gst'= 6.0% y ADNmt: Gst'= 10% . 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.

  7. Focused abdominal sonography for trauma (FAST) in blunt paediatric abdominal trauma

    Objective: To evaluate the role of focussed abdominal sonography for trauma in blunt paediatric abdominal trauma patients, and to see if the role of computed tomography scan could be limited to only those cases in which sonography was positive. Methods: The retrospective study covered 10 years, from January 1, 2000 to December 31, 2009, and was conducted at the Department of Radiology and Department of Emergency Medicine, Aga Khan University Hospital, Karachi. It comprised cases of 174 children from birth to 14 years who had presented with blunt abdominal trauma and had focussed abdominal sonography for trauma done at the hospital. The findings were correlated with computed tomography scan of the abdomen and clinical follow-up. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of focussed abdominal sonography for trauma were calculated for blunt abdominal trauma. SPSS 17 was used for statistical analysis. Results: Of the total 174 cases, 31 (17.81%) were later confirmed by abdominal scan. Of these 31 children, sonography had been positive in 29 (93.54%) children. In 21 (67.74%) of the 31 children, sonography had been true positive; 8 (25%) (8/31) were false positive; and 2 (6%) (2/31) were false negative. There were 6 (19.3%) children in which sonography was positive and converted to laparotomy. There was no significant difference on account of gender (p>0.356). Focussed abdominal sonography for trauma in the study had sensitivity of 91%, specificity of 95%, positive predictive value of 73%, and negative predictive value of 73% with accuracy of 94%. All patients who had negative sonography were discharged later, and had no complication on clinical follow-up. Conclusions: Focussed abdominal sonography for trauma is a fairly reliable mode to assess blunt abdominal trauma in children. It is a useful tool to pick high-grade solid and hollow viscous injury. The results suggest that the role of computed tomography scan can be

  8. Chronical abdominal pain in children: management in the Communitary Medical Consultation Dolor abdominal crónico en niños: conducta en la consulta médica comunitaria

    Lorenzo Pérez Romano

    Full Text Available The term recurrent abdominal pain is characterized by the presence of three or more episodes of abdominal pain in a three-months period although in clincal practice, this term is applied to intermittent episodes of pain in a period of more than one month. This definition is arbitrary causing debates and errors in diagnosing the patient. The term chronic abdominal pain is accepted nowadays which is the one that comprises the constant or intermittent abdominal pain of long duration, functional or organic. In this paper a bibliographical review on chronic abdominal pain in children is carried out. A critical analysis of the evaluation of the patient with this disorders is done as well as the management to follow with them in the primary attention and, the pharmachlogical and non pharmachlogical treatment of the patient with functional pain.
    El término dolor abdominal recurrente se caracteriza por la presencia de tres o más episodios de dolor abdominal, durante un período de tres meses, aunque en la práctica clínica, el término se aplica también a episodios intermitentes de dolor de más de un mes de duración. La definición es arbitraria y ha originado controversias y errores en el diagnóstico; la que se acepta actualmente es dolor abdominal crónico, que comprende específicamente el dolor abdominal constante o intermitente, de larga duración, funcional u orgánico. En el presente trabajo se realiza una revisión bibliográfica sobre el dolor abdominal crónico en edad pediátrica, su etiología, clasificación actual y diagnóstico; se realiza un análisis crítico de la evaluación de los pacientes con estos trastornos, de la conducta a seguir con ellos en la atención comunitaria, y del tratamiento no farmacológico y farmacológico de los pacientes con dolor funcional.

  9. Reducing Abdominal Fat Deposition in Broiler Through Feeding Management

    Cecep Hidayat

    2015-09-01

    Full Text Available Abdominal fat in broiler carcass is considered as a waste and its existence reduces the carcass quality. Abdominal fat deposition is affected by several factors such as genetic, nutrition, feed, sex, age and environment. Reducing abdominal fat deposition can be carried out by regulating the nutrient intake to ensure that no excessive nutrient was consumed. Nutrition effects to reduce abdominal fat deposition are associated with nutrient concentration of ration and quantity of daily feed intake. Daily nutrient intake can be limited, especially through restricted feeding. It is concluded that an appropriate feeding management can reduce abdominal fat deposition in broiler.

  12. Removal of Intra-abdominal Visceral Adipose Tissue Improves Glucose Tolerance in Rats: Role of Hepatic Triglyceride Storage

    Foster, Michelle T.; Shi, Haifei; Seeley, Randy J.; Woods, Stephen C.

    2011-01-01

    Epidemiological studies have demonstrated a strong link between increased visceral fat and metabolic syndrome. In rodents, removal of intra-abdominal but non-visceral fat improves insulin sensitivity and glucose homeostasis, though previous studies make an imprecise comparison to human physiology because actual visceral fat was not removed. We hypothesize that nutrient release from visceral adipose tissue may have greater consequences on metabolic regulation than nutrient release from non-vis...

  13. Diagnostic imaging of infantile abdominal cystic disease

    Thirty-seven patients with infantile abdominal cystic disorders were studied by ultrasound (US), computed tomography (CT), or magnetic resonance imaging (MRI). US studies are simple to conduct, and commonly show an echo-free mass, but tend to yield hyperechoic images when fat and blood are present in the cystic fluid. CT studies, which distinctly demonstrate water, fat, soft tissue density and calcification, are very helpful in the diagnosis of cystic tumor, especially cystic teratoma. MR imaging, which is capable of distinguishing the nature of the cystic fluid (e.g., serous, chylous, bloody, fatty, etc.), is useful in the diagnosis of lymphangioma, teratoma, and torsion of ovarian cystic tumor. Based on the results of the present study, US may be considered to be the modality of first choice in the examination of infantile abdominal cystic disorders, and MRI and/or CT should be employed additionally as necessary in that order.

  14. Drug Therapy for Small Abdominal Aortic Aneurysm

    Ramachandran Meenakshisundaram

    2010-03-01

    Full Text Available Abdominal aortic aneurysm is often asymptomatic, less recognized, and causes considerable mortalityand morbidity, if missed. The incidence varies from country to country and the occurrence is influencedby modifiable (smoking, coronary heart disease, hypertension, dyslipidemia, and prolonged steroid therapyand non-modifiable risk factors (increasing age, male gender, and positive family history. Most ofthe patients with such aneurysm do not exhibit symptoms and the diagnosis is made accidentally duringroutine medical investigations, abdominal ultrasonography, or by an astute surgeon during an abdominalprocedure. Sometimes the diagnosis is made in an emergency room, if the attending resident/doctor isaware of it. Despite good diagnosis and effective management, the outcomes of complicated cases arepoor and the treatment cost is prohibitive. Hence, we reviewed the literature to find out the pathogenesisof such aneurysms and the usefulness of available drugs in its prevention.

  15. Evidence-based diagnosis of abdominal trauma

    Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a ''focused assessment with sonography for trauma'' (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for ''wait and see'' treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences. (orig.)

  16. Abdominal pregnancy as a cause of hemoperitoneum

    Shafi Sheikh

    2009-01-01

    Full Text Available The coexistence of intrauterine and extrauterine pregnancy, the heterotopic pregnancy, is a rare obstetric phenomenon. The preoperative diagnosis of this condition is very difficult; leading to a higher maternal morbidity and fetal loss. We experienced a case of intrauterine pregnancy and ruptured abdominal pregnancy implanted on the illeocaecal region in a 26-year-old primiparous woman. She was clinically misdiagnosed as a case of ruptured ectopic pregnancy, but ultrasonography showed it to be a case of heterotopic pregnancy. Subsequently, the patient was subjected to laparotomy and the ruptured abdominal pregnancy was evacuated. She continued with the intrauterine pregnancy till term and delivered a healthy female baby. Although this condition is unusual, any general surgeon in the emergency department must be aware of this complication and its management, which is often initially misdiagnosed.

    Analysis of the surgical criteria for reintervention in Abdominal Surgery led to the accentuation of a certain number of pictures of occlusion, general infectious syndromes, postoperative peritonitis, gastro-intestinal fistula and hemorrhagic syndrome. In all cases, the clinical examination can be misleading in particular in the case of peritonitis, and the history and non-surgical criteria must be strongly borne in mind. PMID:2036

    We describe here a case of abdominal abscesses due to Mycobacterium fortuitum following liposuction. The abscesses developed three months after the procedure and diagnosis was delayed for five months. The clues for diagnosis were persistent pus discharge in spite of broad spectrum antibiotics and failure to grow any organisms on routine culture. This condition has been rarely reported; however, the increasing number of liposuction procedures done and awareness among physicians will probably r...

  19. Computed tomography of pediatric abdominal masses

    Ultrasonography is a very useful diagnostic modality for evaluation of the pediatric abdominal masses, due to faster, cheaper, and no radiation hazard than CT. But CT has more advantages in assessing precise anatomic location, and extent of the pathologic process, and also has particular value in defining the size, relation of the mass to surrounding organs and detection of lymphadenopathy. We analyzed CT features of 35 cases of pathologically proven pediatric abdominal masses for recent 2 years at Ewha Woman's University Hospital. The results were as follows: 1.The most common originating site was kidney (20 cases, 57.1%); followed by gastrointestinal (5 cases, 14.3%), nonrenal retroperitoneal (4 cases, 11.4%), hepatobiliary (3 cases, 8.6%), and genital (3 cases, 8.6%) in order of frequency. 2.The most common mass was hydronephrosis (11 cases, 31.4%), Wilms' tumor (7 cases, 20.0%), neuroblastoma, choledochal cyst, periappendiceal abscess (3 cases, 8.6%, respectively), ovarian cyst (2 cases, 5.7%) were next in order of frequency. 3.Male to female ratio was 4:5 and choledochal cyst and ovarian cyst were found only in females. The most prevalent age group was 1-3 year old (12 cases, 34.3%). 4.With CT, the diagnosis of hydronephrosis was easy in all cases and could evaluate of its severity, renal function and obstruction site with high accuracy. 5.Wilms' tumor and neuroblastoma were relatively well differentiated by their characteristic CT features; such as location, shape, margin, middle cross, calyceal appearance and calcification, etc. 6.Ovarian and mensentric cysts had similar CT appearance. 7.In other pediatric abdominal masses, CT provided excellent information about anatomic detail, precise extent of tumor and differential diagnostic findings. So, CT is useful imaging modality for the demonstration and diagnosis of abdominal mass lesions in pediatric patients

  20. Laparoscopic biopsy in patients with abdominal lymphadenopathy

    Bhandarkar D

    2007-01-01

    Full Text Available Background: Abdominal lymphadenopathy (AL - a common clinical scenario faced by clinicians - often poses a diagnostic challenge. In the absence of palpable peripheral nodes, tissue has to be obtained from the abdominal nodes by image-guided biopsy or surgery. In this context a laparoscopic biopsy avoids the morbidity of a laparotomy. Aim: This retrospective analysis of prospectively collected data represents our experience with laparoscopic biopsy of abdominal lymph nodes. Materials and Methods: Between October 2000 and November 2005, 28 patients with AL underwent laparoscopic biopsy. Pre-operative radiological imaging studies had identified a nodal mass in 20, a solitary node in 1, a cold abscess in 1 and a mesenteric cystic lesion in 1 patient. In five patients with chronic right lower abdominal pain and normal ultra-sonographic findings mesenteric nodes were identified and biopsied during diagnostic laparoscopy. Results: The sites of biopsied lymph nodes included para-aortic (10, mesenteric (8, external iliac (3, left gastric (2, obturator (1, aorto-caval (1 and porta hepatis (1. One patient with enlarged peripancreatic nodes mass and another with a mesenteric cystic mass had cold abscesses drained in addition to biopsy. There were no perioperative complications and the median postoperative stay was 2 days (range 1-4 days. Histopathology revealed tuberculosis in 23 patients, reactive adenitis in 2, lymphoma in 1 metastatic carcinoma in 1, and a retroperitoneal sarcoma in 1. Conclusions: In patients with AL, laparoscopy provides a safe and effective means of obtaining biopsy. It is of particular value in patients in whom (a the nodes are small or present in locations unsuitable for image-guided biopsy, (b adequate tissue cannot be obtained by image-guided biopsy or (c previously undiagnosed lymphadenopathy is encountered during diagnostic laparoscopy.

    2011-05-01

    Spontaneous sac size regression of a giant abdominal aortic aneurysm (AAA) is a rare event that has not been previously described. We report a case of an 89-year-old woman with a known 9-cm AAA, which was diagnosed in 2003. The patient had refused any kind of treatment at that time. Recent imaging studies obtained 7 years later revealed an AAA of 4 cm diameter. This is the first recorded case of significant spontaneous AAA sac shrinkage. PMID:21444348

However, pathological examination of surgical specimen confirmed Schistosoma mansoni eggs in the biospy. A decrease in the mass volume was noticed under medical treatment (Biltricide. The aim of this report was to intimate clinicians on possible abdominal schistosomiasis as differential diagnosis of childhood abdominal mass. This is a clarion call for a high index of suspicion of childhood abdominal schistosomiasis in children presenting with abdominal mass in a tropical setting.

    AIM: To estimate the prevalence of inherited and acquired thrombophilic risk factors in patients with abdominal venous thrombosis and to compare the risk factor profiles between Budd-Chiari syndromes (BCS) and splanchnic vein thrombosis (SVT).METHODS: In this retrospective study, 36 patients with abdominal venous thrombosis were studied.The patients were divided into Budd-Chiari group (hepatic vein, IVC thrombosis) and splanchnic venous thrombosis group (portal, splenic, superior mesenteric veins) based on the veins involved. Hereditary and acquired thrombophilic risk factors were evaluated in all patients.RESULTS: Twenty patients had SVT, 14 had BCS,and 2 had mixed venous thrombosis. Ten patients (28%) had hereditary and 10 patients (28%) acquired thrombophilic risk factors. The acquired risk factors were significantly more common in the SVT group (SVT vs BCS:45% vs 7%,x2=5.7,P=0.02) while hereditary risk factors did not show significant differences between the two groups (SVT vs BCS: 25%vs 36%, x2=0.46,P=0.7). Multiple risk factors were present in one (7%) patient with BCS and in 3 patients (15%) with SVT. No risk factors were identified in 57% of patients with BCS and in 45% of patients with SVT.CONCLUSION: Hereditary and acquired risk factors play an important role in the etiopathogenesis of abdominal venous thrombosis. Acquired risk factors are significantly more common in SVT patients while hereditary factors are similar in both groups.

  8. Sagittal Abdominal Diameter: Application in Clinical Practice

    2014-05-01

    Full Text Available Excess visceral fat is associated with cardiovascular risk factors. Sagittal abdominal diameter (SAD has recently been highlighted as an indicator of abdominal obesity, and also may be useful in predicting cardiovascular risk. The purpose of the present study was to review the scientific literature on the use of SAD in adult nutritional assessment. A search was conducted for scientific articles in the following electronic databases: SciELO , MEDLINE (PubMed and Virtual Health Library. SAD is more associated with abdominal fat (especially visceral, and with different cardiovascular risk factors, such as, insulin resistance, blood pressure, and serum lipoproteins than the traditional methods of estimating adiposity, such as body mass index and waist-to-hip ratio. SAD can also be used in association with other anthropometric measures. There are still no cut-off limits established to classify SAD as yet. SAD can be an alternative measure to estimate visceral adiposity. However, the few studies on this diameter, and the lack of consensus on the anatomical site to measure SAD, are obstacles to establish cut-off limits to classify it.

  9. Midgut malrotation with chronic abdominal pain

    Anil K Wanjari

    2012-01-01

    Full Text Available Abnormalities in midgut rotation occur during the physiological herniation of midgut between the 5 th and 10 th week of gestation. The most significant abnormality is narrow small bowel mesentery which is prone to volvulus. This occurs most frequently in the neonatal period, less commonly midgut malrotation presents in adulthood with either acute volvulus or chronic abdominal symptoms. It is the latter group that represents a diagnostic challenge. We report a case of a 17-year-old male patient who presented with 10-year history of nonspecific gastro-intestinal symptoms. After extensive investigation the patient was diagnosed with midgut malrotation following computed tomography of abdomen. The patient was treated with a laparoscopic Ladd′s procedure and at 3 months he was gaining weight and had stopped vomiting. A laparoscopic Ladd′s procedure is an acceptable alternative to the open technique in treating symptomatic malrotation in adults. Midgut malrotation is a rare congenital anomaly which may present as chronic abdominal pain. Abdominal CT is helpful for diagnosis.

  10. Intra-abdominal hypertension and acute pancreatitis.

    Mifkovic, A; Skultety, J; Sykora, P; Prochotsky, A; Okolicany, R

    2013-01-01

    Intra-abdominal hypertension (IAH) contributes to organ dysfunction and leads to the development of the abdominal compartment syndrome (ACS). IAH and ACS are relatively frequent findings in patiens with severe acute pancreatitis (SAP) and are associated with deterioration in organ functions. The most affected are cardiovascular, respiratory and renal functions. The incidence of IAH in patients with SAP is approximately 60-80%. There is an accumulating evidence in human and animal studies that changes of perfusion, particularly to the microvasculature, are crucial events in the progression of acute pancreatitis (AP). The perfusion of the small and large intestine is impaired due to reduced arterial pressure, increased vascular resistence and diminished portal blood flow. Bacterial translocation has been described in patients with ACS, and this may apply to patients with SAP. Approximately 30-40% of SAP patients develop ACS because of pancreatic (retroperitoneal) inflammation, peripancreatic tissue edema, formation of fluid collections or abdominal distension. Surgical debridement was the preferred treatment to control necrotizing pancreatitis in the past. However, the management of necrotizing pancreatitis has changed over the last decade. The main objective of this article is to describe the association between IAH and AP and to emphasize this situation in clinical praxis as well (Fig. 1, Ref. 38). PMID:23406186

  11. CT of hemodynamically unstable abdominal trauma

    This article is an appraisal of the use of CT in the management of patients with unstable abdominal trauma. We examined 41 patients with abdominal trauma using noncontrast dynamic CT. In 17 patients a postcontrast dynamic CT was also carried out. On CT, 25 patients had hemoperitoneum. Thirteen patients had splenic, 12 hepatic, 6 pancreatic, 8 bowel and mesenteric, 12 renal and 2 vascular injuries. Seven patients had retroperitoneal and 2 patients adrenal hematomas. All but five lesions (three renal, one pancreatic, and one splenic) were hypodense when CT was performed earlier than 8 h following the injury. Postcontrast studies (n = 17), revealed 4 splenic, 3 hepatic, 1 pancreatic, 3 renal, and 2 bowel and mesenteric injuries beyond what was found on noncontrast CT. Surgical confirmation (n = 21) was obtained in 81.81 % of splenic, 66.66 % of hepatic, 83.33 % of pancreatic, 100 % of renal, 100 % of retroperitoneal, and 85.71 % of bowel and mesenteric injuries. The majority of false diagnoses was obtained with noncontrast studies. Computed tomography is a remarkable method for evaluation and management of patients with hemodynamically unstable abdominal trauma, but only if it is revealed in the emergency room. Contrast injection, when it could be done, revealed lesions that were not suspected on initial plain scans. (orig.)

  12. Computed tomography in therapy planning: Abdominal region

    The radiotherapy community is continuing to appreciate the significant contribution CBT can make to planning abdominal radiotherapy and is also beginning to appreciate the pitfalls and limitations of the technique. Specific attention should continue to focus on patient registration with the scanner and simulator radiographs, patient position during scanning and treatment, and effects of involuntary patient motion, especially breathing, on organ and tumor localization. Effects of patient positional changes and of involuntary motion during treatment on treatment planning and execution should be quantitated, as should effects of inhomogeneities, especially gut air, on abdominal dose distribution. Radiotherapy planned with CBT data can impact significantly on morbidity and mortality associated with abdominal malignancies. Faster scanners (with a scanning time of 9 sec or less) should be employed where possible to obtain maximum diagnostic information. Multiplanar reconstruction and true three-dimensional treatment planning can enhance significantly the value of CBT in treatment planning. Radiotherapists, radiodiagnosticians, radiation physicists, and oncologists must be continue to meet the challenge of realizing the true potential of CBT for the benefit of the cancer patients entrusted to their care

  13. Multidetector CT of blunt abdominal trauma.

    Soto, Jorge A; Anderson, Stephan W

    2012-12-01

    The morbidity, mortality, and economic costs resulting from trauma in general, and blunt abdominal trauma in particular, are substantial. The "panscan" (computed tomographic [CT] examination of the head, neck, chest, abdomen, and pelvis) has become an essential element in the early evaluation and decision-making algorithm for hemodynamically stable patients who sustained abdominal trauma. CT has virtually replaced diagnostic peritoneal lavage for the detection of important injuries. Over the past decade, substantial hardware and software developments in CT technology, especially the introduction and refinement of multidetector scanners, have expanded the versatility of CT for examination of the polytrauma patient in multiple facets: higher spatial resolution, faster image acquisition and reconstruction, and improved patient safety (optimization of radiation delivery methods). In this article, the authors review the elements of multidetector CT technique that are currently relevant for evaluating blunt abdominal trauma and describe the most important CT signs of trauma in the various organs. Because conservative nonsurgical therapy is preferred for all but the most severe injuries affecting the solid viscera, the authors emphasize the CT findings that are indications for direct therapeutic intervention.

Este fenómeno es parte de la crisis actual del capitalismo global, la cual ha tomado la forma, en el caso de la sociedad mexicana, de una profunda crisis orgánica constituida por un déficit de racionalidad (más de tres décadas sin crecimiento económico y un déficit de legitimidad institucional. Esto ha llevado al país a altos niveles de violencia e inseguridad pública sin precedentes en la historia reciente de México, así como a la militarización del aparato de Estado, comprometido en una guerra fallida contra el narcotráfico.

  15. Inter-observer agreement for abdominal CT in unselected patients with acute abdominal pain

    The level of inter-observer agreement of abdominal computed tomography (CT) in unselected patients presenting with acute abdominal pain at the Emergency Department (ED) was evaluated. Two hundred consecutive patients with acute abdominal pain were prospectively included. Multi-slice CT was performed in all patients with intravenous contrast medium only. Three radiologists independently read all CT examinations. They recorded specific radiological features and a final diagnosis on a case record form. We calculated the proportion of agreement and kappa values, for overall, urgent and frequently occurring diagnoses. The mean age of the evaluated patients was 46 years (range 19-94), of which 54% were women. Overall agreement on diagnoses was good, with a median kappa of 0.66. Kappa values for specific urgent diagnoses were excellent, with median kappa values of 0.84, 0.90 and 0.81, for appendicitis, diverticulitis and bowel obstruction, respectively. Abdominal CT has good inter-observer agreement in unselected patients with acute abdominal pain at the ED, with excellent agreement for specific urgent diagnoses as diverticulitis and appendicitis.

  17. Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

    Sugrue, Michael

    2012-01-31

    BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

    Purpose: To evaluate the natural history of children with abdominal Burkitt's lymphoma who had complete clinical remission and residual abdominal mass after treatment. Material and methods: The charts and imaging findings of all children with abdominal Burkitt's lymphoma treated and followed at our medical center between 1988 and 1999 were reviewed for the presence, management, clinical course, and prognosis of residual mass. Results: Only children who achieved complete clinical remission were included. The study group consisted of 33 children (20 boys and 13 girls) aged 2.6-17.6 years (mean 7.2 years). Of these, seven (20.6 %) were found to have a residual abdominal mass. Two underwent second-look operation with no evidence of viable tumor on histology. The remaining five were followed by imaging studies for 2.2-9.1 years (mean 6.1 years); none relapsed. Conclusion: Residual mass is not uncommon in children with abdominal Burkitt's lymphoma. The presence of residual mass in a child with complete clinical remission does not alter the long-term prognosis. Therefore, in children with Burkitt's lymphoma and residual mass with no other signs of disease activity, expectant watching may be appropriate. (orig.)

Con el fin de ilustrar este campo, se presentan algunos aportes y/o investigaciones tanto a nivel general como de la región costa Caribe colombiana. Se ha encontrado que el concepto de salud mental implica el desarrollo de estilos de vida y de características personales, interpersonales, sociales y laborales que apuntan a una idea integrada de bienestar biopsicosocial. De esta forma, la salud mental se entiende que sobrepasa y no es reducida a la simple ausencia de síntomas.

  9. Evaluation of Forty-Nine Patients with Abdominal Tuberculosis

    Murat Kilic

    2014-12-01

    Full Text Available Aim: Abdominal tuberculosis is an uncommon form of extrapulmonary infection. In this study, we aimed to highlight the nonspecific clinical presentations and diagnostic difficulties of abdominal tuberculosis. Material and Method: Clinical features, diagnostic methods, and the therapeutic outcomes of 49 patients diagnosed as abdominal tuberculosis between 2003 and 2014 were retrospectively analyzed. Results: The patients were classified into four subgroups including peritoneal (28, nodal (14, intestinal (5, and solid organ tuberculosis (2. The most frequent symptoms were abdominal pain, abdominal distention and fatique. Ascites appeared to be the most frequent clinical finding. Ascites and enlarged abdominal lymph nodes were the most frequent findings on ultrasonography and tomography. Diagnosis of abdominal tuberculosis was mainly depended on histopathology of ascitic fluid and biopsies from peritoneum, abdominal lymph nodes or colonoscopic materials. Forty patients healed with standart 6-month therapy while extended treatment for 9-12 months was needed in 8 whom had discontinued drug therapy and had persistent symptoms and signs. One patient died within the treatment period due to disseminated infection. Discussion: The diagnosis of abdominal tuberculosis is often difficult due to diverse clinical presentations. The presence of ascites, personal/familial/contact history of tuberculosis, and coexisting active extraabdominal tuberculosis are the most significant marks in diagnosis. Diagnostic laparoscopy and tissue sampling seem to be the best diagnostic approach for abdominal tuberculosis.

    Full Text Available La forma tradicional de evaluar el estado de conciencia de un individuo, ha sido mediante la aplicación de estímulos y el análisis de sus respuestas, sin embargo, esta técnica se ve limitada cuando el individuo es incapaz de responder evidentemente ante un estímulo, como es el caso de los pacientes en estados derivados del coma. 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.

    Full Text Available In a recent paper in Frontiers Cohen et al. (2012 asked What does galvanic vestibular stimulation actually activate? and concluded that galvanic vestibular stimulation (GVS causes predominantly otolithic behavioural responses. In this Perspective paper we show that such a conclusion does not follow from the evidence. The evidence from neurophysiology is very clear: galvanic stimulation activates primary otolithic neurons as well as primary semicircular canal neurons (Kim and Curthoys, 2004. Irregular neurons are activated at lower currents. The answer to what behaviour is activated depends on what is measured and how it is measured, including not just technical details, such as the frame rate of video, but the exact experimental context in which the measurement took place (visual fixation vs total darkness. Both canal and otolith dependent responses are activated by GVS.

    2009-01-01

    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

    Intra-abdominal infection is defined as the presence of an infectious process within the peritoneal cavity. It may be local or have a systemic consequence generating multiple organic disfunction. Most of the studies report a mortality of 30% in severe intra-abdominal infection. Secondary peritonitis is caused by the loss of integrity of the gastrointestinal apparatus, which contaminates with pathogens the peritoneal cavity. Invariably they are polymicrobial infections, mostly due to facultative anaerobic and anaerobic Gram negative bacilli. Prognosis of peritonitis depends on the struggle between two forces: local and systemic immunity of the host and the volume, nature and length of the contamination. Microorganisms and their products estimulate cellular defenses in the host and activate numerous inflammatory mediators responsible for sepsis. Antibiotic treatment of secondary peritonitis must act mainly against Escherichia coli and Bacteroides fragilis. The adequate and early empirical administration of antibiotics against these bacteria is well established. It is necessary to consider if the infection is localized or generalized and if it is accompanied or not by organic disfunction. It also has to be taken into account if peritonitis is community or hospital-acquired when choosing the antibiotic scheme. In community-acquired peritonitis with low to moderate infections a combination of metronidazole-ceftriaxone, metronidazole-gentamycin or a monodrug like ampicillin-sulbactam may be used. In severe hospital-acquired peritonitis imipenem or the combination piperacillin-tazobactam are effective. New quinolones such as trovafloxacin or clinafloxacin, with excellent activity against aerobes and anaerobes producing intra-abdominal infections, may be effective. Future clinical trials are needed to determine their utility. Tertiary peritonitis represent a systemic inflammatory response with multiorganic failure due to the uncontrolled activation of the inflammatory

  20. Abdominal irradiation modulates 5-Fluorouracil pharmacokinetics

    Full Text Available Abstract Background Concurrent chemoradiation with 5-fluorouracil (5-FU is widely accepted for treatment of abdominal malignancy. Nonetheless, the interactions between radiation and 5-FU remain unclear. We evaluated the influence of abdominal irradiation on the pharmacokinetics of 5-FU in rats. Methods The radiation dose distributions of cholangiocarcinoma patients were determined for the low dose areas, which are generously deposited around the intrahepatic target volume. Then, corresponding single-fraction radiation was delivered to the whole abdomen of Sprague-Dawley rats from a linear accelerator after computerized tomography-based planning. 5-FU at 100 mg/kg was intravenously infused 24 hours after radiation. A high-performance liquid chromatography system equipped with a UV detector was used to measure 5-FU in the blood. Ultrafiltration was used to measure protein-unbound 5-FU. Results Radiation at 2 Gy, simulating the daily human treatment dose, reduced the area under the plasma concentration vs. time curve (AUC of 5-FU by 31.7% compared to non-irradiated controls. This was accompanied by a reduction in mean residence time and incremental total plasma clearance values, and volume of distribution at steady state. Intriguingly, low dose radiation at 0.5 Gy, representing a dose deposited in the generous, off-target area in clinical practice, resulted in a similar pharmacokinetic profile, with a 21.4% reduction in the AUC. This effect was independent of protein binding capacity. Conclusions Abdominal irradiation appears to significantly modulate the systemic pharmacokinetics of 5-FU at both the dose level for target treatment and off-target areas. This unexpected and unwanted influence is worthy of further investigation and might need to be considered in clinical practice.

  1. Late renal function following whole abdominal irradiation

    Sixty patients treated with whole abdominal radiotherapy who had remained disease-free since completion of treatment participated in a study to assess the late clinical and biochemical effects of bilateral renal irradiation. Minimum follow-up was 5 years with a maximum of 20 years and a median of 9 years. Fifty-two patients in the study group were treated for primary ovarian cancer. Seven had non-Hodgkins lymphoma arising in the gastrointestinal tract and one patient had a carcinoid tumour arising in small bowel. None of the patients received chemotherapy. Abdominal radiation was given using an open beam technique to a mean dose of 22.92 Gy (range 6.68-27.54 Gy) in 1.02 to 1.25 Gy fractions treated once daily. Posterior kidney shields were used in order to limit the renal dose to <20 Gy. Mean radiation dose to both kidneys (retrospectively calculated) was 19.28 Gy (range 6.68-22.99 Gy). Patients ranged in age from 32-81 years with a median of 61 years. No patient had clinical evidence of renal impairment. Nine patients were hypertensive prior to radiotherapy and a further five patients became hypertensive after treatment. Serum creatinine values ranged from 44-123 μmol/l, with a mean of 87 μmol/l. Creatinine clearance ranged from 0.61-2.38 ml/s (mean 1.28 ml/s). Tubular function tests revealed one borderline high 24-h protein excretion and normal 24-h phosphorous and uric acid. Using a multiple linear regression analysis with creatinine clearance as the endpoint, age was the only significant variable (P < 0.00001) and renal dose and interval from treatment were not independently significant. There was no evidence of late renal toxicity more than 5 years after whole abdominal radiotherapy delivered with this technique and dose/fractionation schedule, and using the clinical and biochemical endpoints assessed in this study

  4. Functional Abdominal Pain: "Get" the Function, Loose the Pain.

    Draeger-Muenke, Reinhild

    2015-07-01

    Functional abdominal pain is a mind-body, psychosocial, and self-reinforcing experience with significant consequences for the sufferer and the surrounding support network. The occurrence of unpredictable symptoms and their severity add an element of dread and feeling out-of-control to daily life and often reduce overall functioning in a downward spiral. Two clinical presentations of functional abdominal pain are offered in this article (composites to protect confidentiality) dealing with abdominal pain syndrome and abdominal migraines. The treatment demonstrates the use of hypnotic principles for self-regulation, exploration, and meaning-making. Hypnosis treatment is conducted in combination with mindfulness-based interventions and Traditional Chinese Medicine's (TCM) teachings regarding abdominal health and illness. The clinical examples illustrate medical findings that suggest children with early life stress and an early onset of gastrointestinal somatization may not simply outgrow their functional abdominal pain but may suffer into adulthood.

    Two patients developed chylous complications following abdominal aortic aneurysm repair. One patient had chylous ascitis and was successfully treated by a peritoneo-caval shunt. The other patient developed a lymph cyst, which gradually resorbed after puncture. Chylous complications following aortic surgery are rare. Patients in bad a general condition should be treated by initial paracentesis and total parenteral nutrition, supplemented by medium-chain triglyceride and low-fat diet. If no improvement is observed on this regimen, the next step should be implementation of a peritoneo-venous shunt, whereas direct ligation of the leak should be reserved for those who are not responding to this treatment.

    2008-01-01

    Full Text Available We describe here a case of abdominal abscesses due to Mycobacterium fortuitum following liposuction. The abscesses developed three months after the procedure and diagnosis was delayed for five months. The clues for diagnosis were persistent pus discharge in spite of broad spectrum antibiotics and failure to grow any organisms on routine culture. This condition has been rarely reported; however, the increasing number of liposuction procedures done and awareness among physicians will probably result in the identification of more cases. Combination antibiotic therapy with surgical drainage in more extensive diseases is essential for cure.

  7. Exercise-related transient abdominal pain (ETAP).

    Morton, Darren; Callister, Robin

    2015-01-01

    Exercise-related transient abdominal pain (ETAP), commonly referred to as 'stitch', is an ailment well known in many sporting activities. It is especially prevalent in activities that involve repetitive torso movement with the torso in an extended position, such as running and horse riding. Approximately 70% of runners report experiencing the pain in the past year and in a single running event approximately one in five participants can be expected to suffer the condition. ETAP is a localized pain that is most common in the lateral aspects of the mid abdomen along the costal border, although it may occur in any region of the abdomen. It may also be related to shoulder tip pain, which is the referred site from tissue innervated by the phrenic nerve. ETAP tends to be sharp or stabbing when severe, and cramping, aching, or pulling when less intense. The condition is exacerbated by the postprandial state, with hypertonic beverages being particularly provocative. ETAP is most common in the young but is unrelated to sex or body type. Well trained athletes are not immune from the condition, although they may experience it less frequently. Several theories have been presented to explain the mechanism responsible for the pain, including ischemia of the diaphragm; stress on the supportive visceral ligaments that attach the abdominal organs to the diaphragm; gastrointestinal ischemia or distension; cramping of the abdominal musculature; ischemic pain resulting from compression of the celiac artery by the median arcuate ligament; aggravation of the spinal nerves; and irritation of the parietal peritoneum. Of these theories, irritation of the parietal peritoneum best explains the features of ETAP; however, further investigations are required. Strategies for managing the pain are largely anecdotal, especially given that its etiology remains to be fully elucidated. Commonly purported prevention strategies include avoiding large volumes of food and beverages for at least 2 hours

    2013-11-01

    Full Text Available Hydronephrosis is a condition that results from complete or partial obstruction of the urinary flow. This paper reports the case of a two-year-old, mixed-breed dog diagnosed with hydronephrosis of the left kidney six months after being kicked in the thoraco-abdominal region. The diagnosis was based on radiographic and ultrasonographic examinations. Percutaneous antegrade pyelography was also performed and allowed the visualization of opacification of the left kidney, which confirmed the diagnosis. Because the exams indicated that the patient had normal renal function, nephrectomy was performed. The patient remained in good health during the postoperative period and in subsequent evaluations.

  11. La Defensa, Política de Estado

    Muñoz-Alonso, Alejandro

    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.

    We report a rare case of huge abdominal desmoid tumour first detected during pregnancy. The patient delivered vaginally and the size of the tumour increased during puerperium for which resection was done. Most of these tumours occur in the abdominal muscles particularly right rectus abdominis, perhaps related to trauma from abdominal stretching and movement. These tumours are known to regress spontaneously after delivery which was not in our case. Subsequent pregnancies do not appear to resul...

  1. [Influences of chest deformation by upper abdominal retractor on respiratory system impedance during abdominal surgery].

    Oka, T; Ozawa, Y; Sato, J

    1999-02-01

    The present study was carried out to clarify the effects of chest deformation by upper abdominal retractor on respiratory system impedance during abdominal surgery. We measured the impedances of respiratory system (RS), lung, and chest wall (CW) in nine anesthetized paralyzed subjects employing a pseudorandom noise forced volume oscillation technique. These measurements were performed before and after the lifting chest wall by upper abdominal retractor. The effects of chest deformation was significant on the impedances of RS, lung, while no discernible effect was found in CW impedance. Lifting chest wall decreased RS resistance which was totally accounted for by the decrease in lung resistance, whereas the lifting did not affect reactance in either RS or lung. The mathematical modeling showed the significant lifting effect on the resistance of the parenchyma. In conclusion, change in RS mechanics produced by chest deformation by upper abdominal retractor is dominated in lung but not in CW. Among the lung mechanical components, parenchyma is the primary site of the lifting effect. PMID:10087819

  2. Prevalence of abdominal migraine and recurrent abdominal pain in a Japanese clinic.

    Hikita, Toshiyuki

    2016-07-01

    Prevalence of abdominal migraine (AM) and recurrent abdominal pain (RAP) was evaluated in patients who visited Hikita Pediatric Clinic between May 2010 and April 2015. Patient data were collected prospectively using a questionnaire. Out of a total of 3611 cases, observed prevalence was 2.44% for repeated abdominal pain over a period of ≥3 months, 1.47% for RAP, and 0.19% for AM. Duration of abdominal pain was longer for AM than for non-AM RAP. Certain clinical features were significantly different between AM and non-AM RAP. No correlations were found among age at onset, frequency of attack, and duration of attack for various types of RAP. It was difficult to determine useful diagnostic criteria for distinguishing between AM and non-AM RAP. They did not appear to be separate disease entities but, instead, lie on a disease spectrum. The present prevalence of AM (0.19%) was lower than that in many previous studies from countries other than Japan. PMID:27460403

  3. A viscoelastic model of the correlation between respiratory lung tumour motion and an external abdominal signal

    Full text: Accuracy of radiotherapy treatment of lung cancer is limited by respiratory induced tumour motion. Compensation for this motion is required to increase treatment efficacy. The lung tumour motion is related to motion of an external abdominal marker, but a reliable model of this correlation is essential. Three viscoelastic systems were developed, in order to determine the best model and analyse its effectiveness on clinical data. Three 1D viscoelastic systems (a spring and dash pot in parallel, series and a combination) were developed and compared using a simulated breathing pattern. The most effective model was applied to 60 clinical data sets (consisting of co-ordinates of tumour and abdominal motion) from multiple treatment fractions of ten patients. The model was optimised for each data set, and efficacy determined by calculating the root mean square (RMS) error between the mo elled position and the actual tumour motion. Upon application to clinical data the parallel configuration achieved an average RMS error of 0.95 mm (superior-inferior direction). The model had patient specific parameters, and displayed good consistency over extended treatment periods. The model ha dled amplitude, frequency and baseline variations of the input signal, and phase shifts between tumour and abdominal motions. This study has shown that a viscoelastic model can be used to cor relate internal lung tumour motion with an external abdominal signal. The ability to handle breathing pattern in'egularities is comparable or better than previous models. Extending the model to a full 3D, pr dictive system could allow clinical implementation for radiotherapy.

  5. Radiation safety actuality in Republic of Moldova

    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

  6. La estructura resistente en la arquitectura actual

    Manterola Armisén, J.

    1998-10-01

    Full Text Available A significant portion in nowadays architecture uses the resistant structures as a fundamental element conveying expression to a building. Resistant structures usually designed, calculated and built by engineers are in some occasions -those that draw our attention now- designed by architects who stress the plastic dimension. Sometimes architects have just tried to soften the elementality of the resistance per se. To abandon the quantitative element to get centered in the qualitative and expressive is a leitmotiv in the architectural proceedings that has been brilliantly fruitful in many an occasion -notice Frei Otto's work among others- but that, in other cases, damages the understanding of the resistant aspect by excessively priorizing the structure appearance upon the structure itself. This article makes a critical account of a series of structures in recent buildings, classified by resistance typologies, flat or spatial trusses, frames, domes, hanging and distensible roofs, tensigrity structures, etc., preceded by a retrospect on how resistance has been traditionally understood.

    Una parte de la arquitectura actual se caracteriza por utilizar la estructura resistente como el elemento expresivo fundamental del edificio. Las estructuras resistentes, diseñadas, calculadas y construidas hasta ahora por ingenieros, han pasado, en algunas ocasiones -las que aquí nos interesan-, a ser diseñadas por arquitectos que acentúan su dimensión plástica. En otras ocasiones los arquitectos se han reducido a dulcificar la elementalidad de lo resistente en cuanto tal. El abandono de lo cuantitativo, para centrarse en lo cualitativo y expresivo, es el "leit motiv" de ese proceder arquitectónico que ha dado frutos muy brillantes en bastantes ocasiones, no hay sino que ver el trabajo de Frei Otto y otros, pero que, en otros casos, perjudican el entendimiento de lo resistente al primar, excesivamente, la apariencia de estructura sobre lo que es la

    Background: Abdominal desmoid tumor is one of the forms of deep (musculoaponeurotic) fibromatosis. It occurs more often as a desmoid tumor in the abdominal wall, less often in various intra-abdominal locations. In this work, we performed retrospective study concerning diagnostic problems of this disease with the use of imaging techniques. Method: Four patients (three females and one male) were examined by postcontrast CT (computed tomography) and one of them also by MR (magnetic resonance). All findings were correlated with the operational findings and histologic examination. Results: The findings were typical only in the case with the lesion located in the abdominal wall, three described cases of the intra-abdominal desmoid provided a broad range of differentially diagnostic possibilities (metastases, GIT tumors, lymphomas, etc.). In particular, the findings in infiltrative processes in intra-abdominal location and retroperitoneal involvement were less typical. Ultimately, the histological findings were decisive. Conclusion: The possibility of the occurrence of intra-abdominal desmoid tumor must be considered particularly in younger individuals with rapidly growing tumorous process, which does not immediately arise from the surrounding organs (digestive tract, internal genitalia, etc.), and is located in the abdominal wall or in the abdominal cavity.

  9. Diagnostic problems of abdominal desmoid tumors in various locations

    Background: Abdominal desmoid tumor is one of the forms of deep (musculoaponeurotic) fibromatosis. It occurs more often as a desmoid tumor in the abdominal wall, less often in various intra-abdominal locations. In this work, we performed retrospective study concerning diagnostic problems of this disease with the use of imaging techniques. Method: Four patients (three females and one male) were examined by postcontrast CT (computed tomography) and one of them also by MR (magnetic resonance). All findings were correlated with the operational findings and histologic examination. Results: The findings were typical only in the case with the lesion located in the abdominal wall, three described cases of the intra-abdominal desmoid provided a broad range of differentially diagnostic possibilities (metastases, GIT tumors, lymphomas, etc.). In particular, the findings in infiltrative processes in intra-abdominal location and retroperitoneal involvement were less typical. Ultimately, the histological findings were decisive.

    Obesity is a progressively prevalent clinical condition increasingly associated with mortality and morbidity from cardiovascular diseases. Visceral fat accumulation worsens such risk and for that reason measuring the waist circumference as a way for evidencing Abdominal Obesity is considered as necessary and important as calculating the Body Mass Index (BMI. The objective of this study is to determine the prevalence of obesity and abdominal obesity and associate them with cardiovascular risk factors. A sample of patients, users of an Integrated Medicine Ambulatory, was analyzed as to age, sex, BMI, waist circumference and clinical conditions such as arterial hypertension, diabetes mellitus type 2, metabolic syndrome (MS, tobacco use and sedentary lifestyle. Patients who already had their waist circumference measured or BMI calculated were selected from the sample, so that 119 patients actually entered the study. Their age mean was 50±13,4 years, 89% were females. The prevalence of obesity and abdominal obesity was 44% and 66% respectively. Both obesity and abdominal obesity were associated with MS (p=0,01, OR=3,42; p=0,0005, OR=7,55 and with each other (p<0,0001, OR=22,1. Circumference measurement was a diagnostic test for MS presenting sensitivity (89.5% and a good negative prediction value (80% in our patients. The prevalence of obesity and abdominal obesity was high in this sample. Obesity and abdominal obesity are associated with MS. These data confirm circumference measurement as an important diagnostic tool in the clinical practice.

    A obesidade é uma condição clínica cuja prevalência aumenta progressivamente e que está cada vez mais associada à morbi-mortalidade cardiovascular. A concentração visceral de gordura aumenta tal risco, portanto, a medida da cintura abdominal, de forma a evidenciar obesidade abdominal, torna-se necessária e tão importante quanto o índice de massa corporal (IMC.

  12. [Endometriosis in the abdominal wall (author's transl)].

    Caligaris, P; Masselot, R; Ducassou, M J; Le Treut, Y; Bricot, R

    1981-01-01

    The authors give 9 case histories of endometriosis localised to the abdominal wall : 3 of them in the umbilicus, 3 in laparotomy incisions (2 of those were Caesareans), 2 of them in the round ligaments at the external opening of the inguinal canal and 1 of them in the right rectus muscle sheath in the abdomen. The functional symptomatology is rhythmical according to menstruation; it is associated with a burning type of pain, a tumour and blood loss. Over and above the theories of aetiology that are now classical, namely tubal retrograde spill, and lymphatic or venous spread, it would seem that prostaglandins and in particular the ratio of P.G.E. divided by P.D.F2 alpha can play a big role. Although Danazol is an effective treatment for endometriosis, the treatment of choice is, in these lesions that are superficial in localisation and easily accessible, to cut them out surgically. This makes it possible on the one hand to look for other intra-abdominal lesions and also on the other hand to confirm the anatomy and pathology (this was done in 7 out of 9 of our cases).

  13. Imaging modalities of abdominal tumors in children

    Further technological progress in cross-sectional imaging modalities, accumuting experience with increasingly refined hardware and software and accumulating specific contrast media allow new algorithms for the assessment of abdominal tumors in children. However, ultrasound remains the diagnostic method of choice: Conventional roentgenology with or without contrast media is decreasing, but often reveals further differential diagnostic details. MRI is becoming more prominent and is often performed immediately after ultrasound. The inauguration of gradient echo sequences and consequent shorter examination times combined with the elimination of pulsation and motion artefacts extends the diagnostic spectrum of the upper and middle abdomen. The application of oral or rectal contrast agents for imaging of the GI tract ameliorates the differentiation of pathologic processes. Recently volumetric CT/ultrafast CT has been gaining in importance for abdominal examinations in the pediatric age group. CT especially is helpful if there are bony structures in the region being examined. CT, however, involves ionizing radiation and timely administration of oral and intravenous contrast material. Moreover, as pediatric radiologists, we must strongly withstand tendencies to perform CT more often because it is less expensive, rather than avoiding ionizing radiation by using MRI. (orig.)

  14. Abdominal lymphadenopathy detection using random forest

    Cherry, Kevin M.; Wang, Shijun; Turkbey, Evrim B.; Summers, Ronald M.

    We propose a new method for detecting abdominal lymphadenopathy by utilizing a random forest statistical classifier to create voxel-level lymph node predictions, i.e. initial detection of enlarged lymph nodes. The framework permits the combination of multiple statistical lymph node descriptors and appropriate feature selection in order to improve lesion detection beyond traditional enhancement filters. We show that Hessian blobness measurements alone are inadequate for detecting lymph nodes in the abdominal cavity. Of the features tested here, intensity proved to be the most important predictor for lymph node classification. For initial detection, candidate lesions were extracted from the 3D prediction map generated by random forest. Statistical features describing intensity distribution, shape, and texture were calculated from each enlarged lymph node candidate. In the last step, a support vector machine (SVM) was trained and tested based on the calculated features from candidates and labels determined by two experienced radiologists. The computer-aided detection (CAD) system was tested on a dataset containing 30 patients with 119 enlarged lymph nodes. Our method achieved an AUC of 0.762+/-0.022 and a sensitivity of 79.8% with 15 false positives suggesting it can aid radiologists in finding enlarged lymph nodes.

  15. Abdominal manifestations of cystic fibrosis in children

    Pulmonary complications remain the main cause of mortality in cystic fibrosis, but the presenting symptoms in children are often related to gastrointestinal or pancreaticobiliary disease. Furthermore, abdominal manifestations are now seen throughout childhood, from infancy to adolescence. The child might present in the neonatal period with meconium ileus or its attendant complications. The older child might present with distal intestinal obstruction syndrome or colonic stricture secondary to high doses of pancreatic enzyme replacement. Less-common gastrointestinal manifestations include intussusception, duodenitis and fecal impaction of the appendix. Most children also show evidence of exocrine pancreatic deficiency. Radiologically, the combination of fat deposition and pancreatic fibrosis leads to varying CT and MR appearances. A higher than normal incidence of pancreatic cysts and calcification is also seen. Decreased transport of water and chloride also increases the viscosity of bile, with subsequent obstruction of the biliary ductules. If extensive, this can progress to obstructive cirrhosis, portal hypertension and esophageal varices. Diffuse fatty infiltration, hypersplenism and gallstones are also commonly seen in these patients. We present a pictorial review of the radiological appearance of these abdominal manifestations. The conditions are dealt with individually, together with typical appearances in various imaging modalities. (orig.)

  17. Abdominal computed tomography in malignant lymphoma

    The computed tomographic findings of malignant lymphoma in the pelvis and abdomen is described. Characteristic symptoms are lymph node enlargement in the diameter greater than 1,0 cm, obliteration of the contour of the surrounding structures and displacement of the neighbouring organs. In contrast to the conventional lymphography, CT gives information about mesenterial and retrocrural lymph nodes. In patients with involvement of liver and spleen, CT defines only the size of the organs, because of differences in density to normal patients are seldom observed and focal lesions are rare. 71 patients with newly diagnosed, histologically proved and untreated malignant lymphoma are investigated by CT. In 27 patients CT detected pathological findings, the sensitivity was 72%, the specifity 100%. False-negative results has been attributed to the failure to identify not enlarged, but involved lymph nodes and involved liver and spleen without focal lesions or enlargement. CT replaces lymphography in diagnosis and staging of patients with abdominal malignant lymphoma, lymphography is indicated only in patients with expected abdominal disease and normal CT to identify involved, not enlarged lymph nodes.

    Full Text Available Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.
