Dos casos de quiste de intestino anterior en cavidad oral

Directory of Open Access Journals (Sweden)

Celso Chuquisana-Mostacero

Full Text Available Antecedentes y Objetivo: El quiste de intestino anterior es una entidad congénita poco frecuente. Cuando aparece, su localización más frecuente es el íleon y, aunque pueden aparecer a lo largo de todo el tracto digestivo, es rara su ubicación en la cavidad oral. A menudo se caracteriza por tres hallazgos principales: presencia de una capa de músculo liso bien desarrollada, una capa epitelial típica de alguna porción del tracto alimentario, y la unión íntima a alguna porción del tracto gastrointestinal. Las lesiones quísticas del suelo de boca en la edad infantil más frecuentes son los quistes salivares y las malformaciones linfáticas, ambas englobables en el término ránula. Sin embargo hay otras posibilidades, y la duplicación de intestino anterior, como aparece en los casos que presentamos, es una de ellas. Material y Método: Presentamos 2 pacientes en edad pediátrica con lesión lingual o de suelo de boca, que tras el estudio de imagen adecuado fueron operados por vía intraoral para la extirpación de la tumoración. En uno de los casos se usó abordaje cervical para extirpación de un segundo locus quístico. Resultados: El estudio anatomopatológico mostró en uno de los casos epitelio respiratorio, y en el segundo mucosa gástrica y epitelio respiratorio. Conclusiones: La importancia del diagnóstico y la extirpación completa en este tipo de lesiones viene dada por el riesgo de degeneración maligna en la edad adulta.

Full Text Available Avaliou-se neste trabalho as características histomorfométricas da mucosa intestinal de tambaqui após uso de probiótico a base de Bacillus spp., veiculado na ração e dissolvido na água durante transporte. Foi utilizado um delineamento inteiramente casualizado com três tratamentos e sete repetições, sendo comparado um tratamento controle (peixes alimentados com ração comercial sem probiótico a dois outros tratamentos envolvendo o uso de probiótico comercial, veiculado na ração ou na água de transporte. Um total de 510 juvenis de tambaqui (peso e comprimento total médio inicial de 83,26±28,14g e 17,39±1,90cm, respectivamente foi distribuído em três tanques de alvenaria. Durante 60 dias, os peixes de dois tanques foram alimentados com ração comercial e os do terceiro tanque com ração comercial suplementada com probiótico. Após este período, os peixes de cada tanque foram divididos em sacos plásticos e transportados por 4 horas de acordo com os seguintes tratamentos: T1 = alimentação com ração comercial (controle; T2 = alimentação com ração comercial e probiótico adicionado na água durante o transporte (20mg/L; T3 = alimentação com ração comercial suplementada com probiótico (1,0g/kg de ração. Antes do transporte (basal, 24 e 96 horas após o transporte, oito peixes de cada tratamento foram submetidos a eutanásia e o intestino retirado para pesagem e mensuração do comprimento para estabelecimento da relação comprimento corporal/ intestino. Em seguida, foi realizada coleta da porção anterior e posterior do intestino, para avaliação das características morfo-histológicas da mucosa intestinal. O uso de probiótico durante o transporte não afetou o peso do intestino de juvenis de tambaqui. O comprimento do intestino do tambaqui não foi alterado pelo tratamento, sendo observada somente relação linear entre o comprimento intestinal e o comprimento corporal (CC dos peixes.

Full Text Available OBJETIVO: Classificar a dor abdominal crônica em crianças e adolescentes por meio dos critérios de Roma II e definir o desfecho diagnóstico em três anos de seguimento. MÉTODOS: Durante um ano, 71 pacientes com dor abdominal crônica foram atendidos como casos novos num ambulatório terciário de gastroenterologia pediátrica. Causas orgânicas foram excluídas por bases clínicas e laboratoriais, e relatos clínicos foram avaliados especificamente quanto à possibilidade de preencherem os Critérios de Roma II para dor abdominal em crianças. Para estabelecer o diagnóstico definitivo, os pacientes foram seguidos por três anos, em média. RESULTADOS: A alocação dos 71 pacientes segundo Roma II foi: doença orgânica (n=12, remissão dos sintomas após a primeira consulta (n=7, ou preencheram os critérios para dor funcional (n=52. Dos 12 pacientes de doença orgânica, nove foram diagnosticados como intolerantes à lactose, mas foram re-alocados para doença funcional no seguimento, visto que a dieta de isenção não aliviou a queixa. Dos 52 pacientes com doença funcional (idade mediana=9,3 anos, 50% meninos, nove, que inicialmente preencheram o critério para dor abdominal funcional, foram re-alocados no diagnóstico de constipação funcional e 43 mantiveram o diagnóstico funcional: 24 com dispepsia funcional, 18 com dor abdominal funcional e um com síndrome do intestino irritável. CONCLUSÕES: Dentre os casos de dor abdominal crônica, a dor do tipo funcional foi mais comum que as causas orgânicas e, dentre os seus subgrupos, a dispepsia funcional foi mais freqüente. O seguimento em longo prazo permitiu estabelecer o diagnóstico definitivo da origem da dor abdominal nessas crianças.OBJECTIVE: To classify chronic abdominal pain in children and adolescents, according to Rome II criteria and to define diagnosis outcome in a three-year follow-up period.

Full Text Available Aim: to study the usefulness and safety of capsule endoscopy as a diagnostic tool in various small bowel disorders. Design: a retrospective analysis of a series of cases. Material and methods: between August 2001 and August 2002, 92 capsule endoscopy procedures were performed in 88 patients (53M/39F, age: 43.87 ± 16.78. Indications included: chronic diarrhea (n = 33; unknown abdominal pain (n = 29; occult gastrointestinal bleeding or iron-deficiency anemia (n = 13; abdominal discomfort in NSAID takers (n = 7; staging of gastrointestinal tumors (n = 4, and asymptomatic controls (n = 2. Previously performed gastroscopy, colonoscopy, and small-bowel follow-through were not conclusive in all patients. Results: most frequently relevant findings included: jejuno-ileal apthas and ulcerations (29 patients, vascular malformations (13 patients, and intestinal neoplasm (6 patients. The groups with a higher rate of findings related to this indication were occult gastrointestinal bleeding (76.92% and chronic diarrhea (67.85%, with the lowest rate in the abdominal pain group (34.48%. Therapeutic strategy was directly changed in 36 of 88 patients (40.90% because of capsule-endoscopic findings. The only observed complication was the failed excretion of one of the capsules because of an unknown ulcerated intestinal stricture. Conclusions: capsule endoscopy is a safe procedure which can study the entire small bowel, meaning a valuable tool for the management of patients with suggestive signs and symptoms of intestinal disorders.Objetivo: estudiar la utilidad y seguridad de la cápsula endoscópica como prueba diagnóstica en distintas patologías de intestino delgado.

las etiologías más frecuentes se localizan a nivel colónico. El objetivo es analizar el manejo diagnóstico-terapéutico de las HDB severas cuya etiología se localizaba en el intestino delgado. Pacientes y métodos: entre 1975 y marzo del 2002 ingresaron en nuestro servicio 12 HDB severas originadas en el intestino delgado. Todos consultaron por rectorragia franca, precisando al menos transfusión de 3 unidades de concentrados de hematíes. La edad media fue de 54 ± 21 años, el 58% eran mujeres, y el 83% había presentado cuadros previos de HDB. Resultados: en once casos (92% se realizó una endoscopia digestiva alta y baja urgente no objetivando el origen del sangrado. La arteriografía se indicó en 7 pacientes (58%, localizando en 5 de ellos el sangrado. En dos casos se hizo una gammagrafía mostrando en uno un divertículo de Meckel y en el otro fue normal. Todos se intervinieron, 8 (67% de urgencias, encontrándose un tumor en 9 casos y un divertículo de Meckel en 3, realizándose resección de todas las lesiones. La histología informó de leiomioma en 7 casos, de divertículo de Meckel en 3, de leiomioblastoma en 1 y de angioma en el caso restante. Tras un seguimiento medio de 132 ± 75 meses, fue éxitus el leiomioblastoma, y recidivó el angioma, el cual fue embolizado radiológicamente con éxito. Conclusiones: la HDB severa de origen en intestino delgado debe considerarse como posibilidad etiológica cuando la endoscopia digestiva no objetiva el origen del sangrado, siendo la arteriografía una técnica diagnóstica útil para localizar el sangrado. La cirugía supone el tratamiento definitivo del proceso, confirma la etiología, y descarta la presencia de malignidad.

2010-03-01

Full Text Available INTRODUÇÃO: A síndrome do intestino curto resulta de comprimento total de intestino delgado inadequado para manter a nutrição, e assim, os pacientes tornam-se cronicamente dependentes de nutrição parenteral total. Numerosas estratégias cirúrgicas foram estudadas para restabelecer a função intestinal normal. OBJETIVO: Propor a utilização da inversão de segmento de alça associada à STEP - Serial Transverse Enteroplasty - para aumentar a área absortiva intestinal em pacientes com síndrome do intestino curto. MÉTODO: Os autores descrevem uma nova alternativa para o tratamento cirúrgico da síndrome do intestino curto, demonstrando sua facilidade e eficiência para o objetivo proposto. RESULTADOS: As duas técnicas associadas permitiram alongar a alça intestinal em 2,6 vezes do comprimento original, com posterior ganho de peso, redução do número de evacuações para uma exoneração ao dia e melhora da qualidade de vida social e psicológica. CONCLUSÃO: Essa técnica de inversão de segmento de alça intestinal e posterior STEP surge como tratamento eficiente e definitivo à síndrome do intestino curto de forma promissora e segura permitindo retorno à alimentação por via oral com satisfatória absorção de nutrientes e ganho de peso, retorno da motilidade efetiva intestinal, associada à baixa morbidade e melhoria da qualidade de vida social e psicológica. Apesar de requerer várias cargas de grampeadores lineares apresenta baixa morbidade e passa a tornar-se um potencial substituto para o transplante intestinal.BACKGROUND: The short bowel syndrome results of inadequate total length of small intestine that is not enough to nutrition, and so, the patients become dependents of total parenteral nutrition. Numerous surgical strategies had been studied to reestablish the normal intestinal function.

Full Text Available En esta Guía de práctica clínica analizamos el manejo diagnóstico y terapéutico de pacientes adultos con estreñimiento y molestias abdominales, bajo el espectro del síndrome del intestino irritable y el estreñimiento funcional. Tienen una importante repercusión personal, sanitaria y social, afectando a la calidad de vida de los pacientes que las padecen. En el síndrome del intestino irritable con predomino del estreñimiento, este es la alteración deposicional predominante junto con dolor abdominal recurrente, hinchazón y distensión abdominal frecuente. El estreñimiento se caracteriza por la dificultad o la escasa frecuencia en las deposiciones, acompañado por esfuerzo excesivo durante la defecación o sensación de evacuación incompleta. La mayoría no tienen una causa orgánica subyacente, considerándose un trastorno funcional intestinal. Poseen muchas similitudes clínicas y fisiopatológicas, con respuesta similar del estreñimiento a fármacos comunes. La diferencia fundamental es la presencia o ausencia de dolor, pero no de un modo evaluable como «todo o nada». La gravedad depende tantro de la intensidad de los síntomas intestinales como de otros factores: asociación de síntomas gastrointestinales y extraintestinales, grado de afectación, formas de percepción y comportamiento. Los criterios de Roma diagnostican los trastornos funcionales intestinales. Esta Guía está adaptada a los criterios de Roma IV (mayo de 2016 y analiza, en esta primera parte, los criterios de alarma, las pruebas diagnósticas y los criterios de derivación entre Atención Primaria y Aparato Digestivo. En una segunda parte, se revisarán las alternativas terapéuticas disponibles (ejercicio, dieta, tratamientos farmacológicos, neuroestimulación de raíces sacras o cirugía, efectuando recomendaciones prácticas para cada una de ellas.

Full Text Available Estudos realizados há mais de 10 anos demonstraram que a deficiência ontogenética de lactase é freqüente na população brasileira. Entretanto, esses estudos se basearam no incremento da glicemia após sobrecarga de doses não utilizadas habitualmente na dieta. Atualmente, aceita-se que a avaliação da absorção da lactose com o teste do hidrogênio no ar expirado é mais apropriada que o teste da curva glicêmica. Por outro lado, a enteropatia ambiental sintomática e/ou assintomática constituem um grave problema de saúde pública em grupos populacionais de baixo nível sócio-econômico de nosso meio. A ocorrência de sobrecrescimento bacteriano no intestino delgado de crianças com enteropatia ambiental, foi caracterizada em crianças moradoras em favelas. Sobrecrescimento bacteriano no intestino delgado é caracterizado pela presença de bactérias pertencentes à flora colônica no intestino delgado. Objetivando avaliar a freqüência de má absorção de lactose e determinar a ocorrência de sobrecrescimento bacteriano no intestino delgado em crianças escolares, através do teste do H2 no ar expirado, investigaram-se 83 alunos de uma escola localizada na região periférica da cidade de Marília, Estado de São Paulo, após sobrecarga oral de lactose e lactulose. Foram colhidas também amostras de fezes para pesquisa de parasitas. Má absorção de lactose foi observada em 19 (22,9% escolares e intolerância à lactose em 10 (12,0%. Sobrecrescimento bacteriano no intestino delgado foi identificado pelo teste do H2 no ar expirado em 6 (7,2% dos 83 escolares. Giardia lamblia foi o parasita mais freqüentemente isolado nas fezes dos escolares. A ocorrência de deficiência ontogenética de lactase observada neste grupo de crianças foi semelhante ao relatado para populações caucasianas. Sobrecrescimento bacteriano foi encontrado neste grupo de crianças assintomáticas, podendo refletir as condições desfavoráveis de seu meio

Full Text Available INTRODUCTION: Mesenteric thrombosis related to trauma is an uncommon entity and has poor prognosis when associated to low perfusion and hemorrhagic shock. Usually presents a challenging diagnosis and high mortality rates, despite appropriate treatment. OBJECTIVE: To relate a case of a car accident and blunt abdominal trauma with terminal ileum and right colon necrosis. CASE REPORT: After initial procedures, complementary exams showed ribs and humerus fractures. Computerized tomography evidenced aerial distension in small bowel, gastric stasis and hidro-pneumothorax. Hypotension was observed during clinical observation followed by cardiopulmonary arrest, responding to reanimation. At surgery, it was found extensive necrosis of right colon and terminal ileum, and an ileum-transversostomy was performed with primary anastomosis. During the staying in intensive care unit, oliguria, miosis, convulsion and pulseless electric activity happened with death in three days after hospital admission. CONCLUSION: Although uncommon, mesenteric ischemia with venous thrombosis might be secondary to blunt abdominal trauma and must be considered in a bad abdominal evolution.INTRODUÇÃO: Trombose mesentérica, relacionada à trauma é entidade incomum com pobre prognóstico quando seguida de estados de baixo fluxo e choque hipovolêmico. Geralmente se apresenta com quadro de difícil diagnóstico, mortalidade elevada a despeito de tratamento adequado. OBJETIVO: Apresentar um caso de vítima de atropelamento que evoluiu com necrose de cólon direito e íleo terminal. RELATO DO CASO: Após admissão hospitalar e atendimento inicial, os exames complementares mostraram fratura de costela e úmero.

Full Text Available JUSTIFICATIVA E OBJETIVOS: A colonoscopia é um exame muito utilizado nos dias atuais para diagnóstico, tratamento e controle de doenças intestinais. A perfuração intestinal, embora rara, é a mais temida complicação deste exame. A correção da perfuração pode ser feita através do uso de clipes posicionados por via endoscópica. O objetivo deste relato de caso foi alertar os especialistas para a ocorrência e o tratamento de síndrome de compartimento abdominal durante pinçamento endoscópio de perfuração intestinal secundário à colonoscopia. RELATO DO CASO: Paciente do sexo feminino, 60 anos, estado físico ASA II, submetida à colonoscopia sob sedação. Durante o exame constatou-se perfuração acidental do intestino e optou-se por tentar pinçar a perfuração por via endoscópica. A paciente evoluiu então com dor e distensão abdominal, pneumoperitônio, síndrome de compartimento abdominal, dispnéia e instabilidade cardiovascular. Realizou-se punção abdominal de emergência, o que determinou a melhora clínica da paciente até que laparotomia de urgência fosse realizada. Após laparotomia exploradora e sutura da perfuração a paciente evoluiu clinicamente bem. CONCLUSÕES: O pinçamento por via endoscópica de perfuração intestinal secundária à colonoscopia pode contribuir para a formação de pneumoperitônio hipertensivo e síndrome de compartimento abdominal, com repercussões clínicas graves que exigem tratamento imediato. Profissionais capacitados e recursos técnicos adequados podem ser fatores determinantes do prognóstico do paciente.JUSTIFICATIVA Y OBJETIVOS: La colonoscopia es un examen utilizado muy a menudo en la actualidad para el diagnóstico, tratamiento y el control de las enfermedades intestinales.

2017-01-01

Full Text Available En el pasado, al referirse a tragedias, los medios de comunicación representaban el único vector que reflejaba el acontecimiento en toda su complejidad. Hoy en día, los medios sociales constituyen un componente esencial del proceso mediático, y son los medios clásicos de prensa los que están conectados al flujo de las redes sociales, de las que, no solo recopilan información, sino también el pulso emocional de la sociedad. El 30 de octubre de 2015, en un club de Bucarest, se produjo un incendio que ocasionó 64 muertes, la mayoría jóvenes. Este estudio se centra en cómo el flujo mediático y las redes sociales en Rumanía se fusionaron y se apoyaron mutuamente, generando efectos secundarios tras la tragedia. El período de seguimiento fue de un mes, desde el 30 de octubre, cuando se produjo la tragedia, hasta el 30 de noviembre. El método de investigación combina el análisis de contenido y la interpretación cualitativa de los datos, con referencia a parámetros como el contexto, el tema del artículo, el estilo, el género periodístico o la relación información/opinión. Las conclusiones de este estudio nos muestran que la conexión entre los medios tradicionales y los medios sociales ha ocasionado un cambio en el paradigma de los medios de comunicación, cuyo resultado es que el papel de los periodistas profesionales como filtro de garantía sigue siendo prioritario.

Full Text Available El sistema de medios públicos en Ecuador está compuesto por 22 medios de diferente origen y estructura, constituyéndose un poder nuevo y sin límites claros, que intenta competir con medios privados y tradicionales del país, cuya administración es de carácter familiar y monopólico. Los medios públicos en Ecuador distan de las características universales planteadas para este tipo de medios, básicamente por la cercanía con los organismos del Estado, en general. La competencia entre medios públicos y privados es desigual, situación que modifica la agenda mediática nacional, dejando a la luz algunas debilidades y limitaciones del ejercicio periodístico y del manejo de la empresa periodística, en particular. El presente artículo se fundamenta en un análisis descriptivo de los medios de comunicación en Ecuador y el juego de poderes que ha desatado la presencia de medios públicos en esta última década. Analizan también el rol del periodismo y su posición frente a los temas vitales para el país, evidenciando la ausencia de una política integral a favor del ciudadano y debilidades en la profesión periodística.

2014-01-01

Full Text Available El avance de la tecnología, en especial, en el ámbito de la comunicación, obliga a los medios a evolucionar constantemente para no morir en un escenario marcado por una serie de transformaciones y cambios mediáticos que han afectado al periodismo como profesión y a los medios de comunicación, proceso que ha generado estudios de todo orden. Este trabajo analiza el panorama mediático digital en Ecuador, las características de cultura periodística y el consumo de contenidos en la Red. Describe las tendencias de los principales medios digitales en el país, seleccionados para realizar un estudio de caso. El artículo toma como referencia central el estudio de las diez tendencias digitales en medios de comunicación de Cerezo-Gilarranz, especialista en estrategias digitales. Posteriormente se identifican las deficiencias que tienen los medios en Ecuador; principalmente por la falta de domino de los entornos tecnológicos y la escasa vinculación del proyecto empresarial y periodístico con soportes tecnológicos e innovadores, como el uso de redes sociales... El resultado final es una guía detallada de las debilidades y las fortalezas de cada medio digital en estudio. Asimismo, este trabajo propone tendencias fiables para que los medios estudiados puedan encaminarse firmes en entornos digitales, asumiendo a las herramientas tecnológicas como oportunidad de negocio y de servicio.

Cuando se estudia la evolución de la convergencia multimedia en los medios de comunicación es frecuente encontrarse con análisis reduccionistas. En muchos de esos análisis tiende a destacarse la tecnología como el único parámetro que promueve los procesos de convergencia y evoluciona con ellos, mientras se olvida o minusvalora otros aspectos. Sin embargo, el proceso actual de convergencia en los medios es mucho más rico en matices. En particular, como trataremos de explicar, en este caso debe...

Dolores Medio ahuyenta las mariposas negras

Anne Marie Poelen

2004-01-01

Full Text Available The article shows why Dolores Medio in her days would have been considered “una chica rara”, analysing three novels of hers which are an excellent reflection of the social, cultural and historical context in which they were written. With these novels Medio tried to make people aware of the injustices that were taking place in the patriarcal in which she lived and wrote. The protest is subtle but tangible, both on a thematic and stylistic level. Dolores Medio proves to have been a strong, independent individual, unlike all but one of the main characters in her literary work.

Presiones empresariales a los medios: El caso de un medio deportivo chileno

Full Text Available El propósito de este artículo es analizar cómo los intereses corporativos modelan el sistema de medios en Chile y el ejercicio periodístico. Las implicancias para la democracia también son consideradas en consideración. Este artículo usa un caso de estudio para mostrar cómo los intereses empresariales operan concretamente en los medios para fortalecer los intereses privados en vez de los públicos. El artículo sugiere que el periodismo chileno está constreñido principalmente por un marco neoliberal, jugando un rol colaborativo para no entorpecer el medioambiente empresarial debido a que éste genera empleos y crecimiento económico para el país. En segundo lugar, el texto explora el caso, analizando en el marco de la perspectiva del periodismo del desarrollo, siguiendo un discurso público más amplio sobre los requerimientos de desarrollo para Chile. De hecho, las corporaciones periodísticas y la esfera económica chilenas están fuertemente relacionadas a pesar de las tensiones de los años recientes en el sistema de medios chileno.

Full Text Available En esta Guía de práctica clínica analizamos el manejo diagnóstico y terapéutico de pacientes adultos con estreñimiento y molestias abdominales, bajo la confluencia del espectro del síndrome del intestino irritable y el estreñimiento funcional. Ambas patologías están encuadradas en los trastornos funcionales intestinales y tienen una importante repercusión personal, sanitaria y social, afectando a la calidad de vida de los pacientes que las padecen. La primera es el subtipo de síndrome del intestino irritable en el que el estreñimiento es la alteración deposicional predominante junto con dolor abdominal recurrente, hinchazón y distensión abdominal frecuente. El estreñimiento se caracteriza por la dificultad o la escasa frecuencia en relación con las deposiciones, a menudo acompañado por esfuerzo excesivo durante la defecación o sensación de evacuación incompleta. En la mayoría de los casos no tiene una causa orgánica subyacente, siendo considerado un trastorno funcional intestinal. Son muchas las similitudes clínicas y fisiopatológicas entre ambos trastornos, con respuesta similar del estreñimiento a fármacos comunes, siendo la diferencia fundamental la presencia o ausencia de dolor, pero no de un modo evaluable como «todo o nada». La gravedad de estos trastornos depende no solo de la intensidad de los síntomas intestinales sino también de otros factores biopsicosociales: asociación de síntomas gastrointestinales y extraintestinales, grado de afectación, y formas de percepción y comportamiento. Mediante los criterios de Roma, se diagnostican los trastornos funcionales intestinales. Esta Guía de práctica clínica está adaptada a los criterios de Roma IV difundidos a finales de mayo de 2016. En una primera parte (96, 97, 98 se analizaron los aspectos conceptuales y fisiopatológicos, los criterios de alarma, las pruebas diagnósticas y los criterios de derivación entre Atención Primaria y aparato digestivo

2015-11-01

Full Text Available La aparición de los movimientos sociales en red ha intensificado el debate sobre la confianza del consumidor en los medios tradicionales. Especialmente, debido a la cobertura mediática de las protestas, la aparición de los medios de comunicación alternativos y a la emergencia de las redes sociales como fuentes de información. A través de los resultados de una encuesta realizada en la #acampadabcn, la plaza ocupada por el Movimiento 15M en Barcelona, se estudia la asociación entre la exposición a los medios de comunicación, la confianza en ellos y la participación política en los movimientos sociales en red, específicamente, entre los activistas del Movimiento 15M. Los resultados indican que los usuarios de medios digitales políticamente involucrados conceden más confianza a la información difundida por los medios alternativos que por los medios convencionales. Por otra parte, la exposición a los medios sociales se asocia con la confianza en los medios, mientras que la edad y el sexo no. Eso significa que, a mayor uso de los medios alternativos y sociales, menor es la confianza en la información proporcionada por los medios tradicionales. En cambio, entre aquellos que no utilizan los medios sociales y son consumidores de medios tradicionales, encontramos mayores porcentajes de confianza en los medios convencionales.

Full Text Available La depreciación efectiva de medios de trabajo o recursos fijos -maquinaria, equipo, edificio, infraestructura, medios de transporte, entre otros-, ocurre por transferencia de su valor al producto final. En una empresa en compra/venta, los recursos fijos depreciados se transmutan en un medio esencial de entrada, para las adquisiciones -parciales y totales- como modo de entrada. Las teorías de empresa han brindado escasa atención a la influencia sustantiva de los medios de trabajo depreciados, en las adquisiciones como modo de entrada. El rol de medio que desempeñan esos recursos depreciados, es evidente en la historia de las coyunturas de mercado; recesión, depresión, crecimiento y prosperidad. En recesión y depresión, dado el desarrollo de las fuerzas productivas, los medios de trabajo depreciados se tornan en recursos estratégicos. La misión de esos recursos es fortalecer y posicionar a la empresa adquiriente en el mercado global. Los recursos depreciados contribuyen a contrarrestar la tendencia a la baja de la tasa media de ganancia de la empresa adquiriente. Esta investigación busca aportar a las teorías de recursos, un modelo de análisis que contribuya a explicar el papel de medio de entrada de los recursos depreciados, en las adquisiciones como modo de entrada.

Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

International Nuclear Information System (INIS)

Marincek, B.

2002-01-01

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.)

van Assen, Tijmen; de Jager-Kievit, Jenneke W A J; Scheltinga, Marc R; Roumen, Rudi M H

2013-01-01

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

Full Text Available OBJETIVO: Realizar um estudo morfométrico comparativo da musculatura longitudinal e circular do intestino delgado de ratos submetidos à construção cirúrgica de um e de dois piloros no intestino delgado utilizando-se da técnica de criação de piloros proposta por Rena et al. MÉTODO: Foram utilizados 52 ratos Wistar machos divididos em três grupos. O Grupo A, destacado como controle, composto de 10 animas, cada um forneceu 20mm de segmento de intestino para o estudo. Os animais do Grupo B, composto de 32 animais, foram submetidos à construção de dois piloros, um a 100mm e outro a 150mm da válvula ileocecal e os animais do grupo C, composto de 10 animais, foram submetidos à construção de um piloro a 100mm da mesma. A eutanásia ocorreu no décimo dia. A morfometria das camadas musculares longitudinal e circular acima e abaixo dos piloros foi estudada com utilização do microscópico modelo "Axiostar plus" conectado à câmera "Axioncam Version 5.05.10" com objetiva X5 / 0,12 no o programa "AxioVision 3.1.2.1". RESULTADOS: As alças apresentaram aumento da espessura da camada muscular acima e abaixo do ponto da operação. O estudo morfométrico comparativo das camadas musculares longitudinal e circular mostrou aumento significativo em comparação ao controle, não demonstrando significância entre os grupos B e C. CONCLUSÃO: Os resultados deste estudo revelaram importante aumento de espessura das camadas musculares, porém, menos acentuados que aqueles descritos na literatura quando foram realizados em animais submetidos à estenose fixa. Esses dados indicam que a construção operatória de piloros pela técnica utilizada promove alterações musculares de menor monta, possivelmente, pela função valvular do piloro.

Abdominal obesity tends to be associated with weight gain and obesity and it is significantly connected with different disorders like coronary heart disease and type II diabetes mellitus.This study was conducted to investigate the efficacy of vacuum therapy as compared to abdominal exercises on abdominal obesity in overweight and obese women. Methods: Thirtyoverweight and obese women participated in this study with body mass index > 25 kg/m2andwaist circumference ≥ 85 cm. Their ages ranged from 28 - 40 years old.The subjects were excluded if they have diabetes, abdominal infection diseases or any physical limitation restricting exercise ability. They were randomly allocated into two equal groups; group I and group II. Group I received vacuum therapy sessions (by the use of LPG device in addition to aerobic exercise training. Group II received abdominal exercises in addition to the same aerobic exercisesgiven to group I. This study was extended for successive 8 weeks (3 sessions/ week. All subjects were assessed for thickness ofnthe abdominal skin fold, waist circumference and body mass index. Results: The results of this study showeda significant difference between group I and group II post-interventionas regarding to the mean values of waist circumference and abdominal skin fold thickness (p<0.05. Conclusion: It can be concluded that aerobic exercises combined with vacuum therapy (for three sessions/week for successive 8 weeks have a positive effect on women with abdominal obesity in terms of reducing waist circumference and abdominal skin fold thickness.

Full Text Available The introduction of the Total Parenteral Nutrition (TPN has given rise to a new hope in the treatment of intestinal failure (LF associated with the Short Bowel Syndrome (SBS. However, together with the TPN and the increase of survival of these patients, new problems and questions have emerged, as well as new therapeutical procedures. Taking into consideration this emerging reality, this paper has the purpose to undertake a review of current concepts and available treatments for patients with IF associated-liver disease. Although TPN provides an increase of survival of patients with intestinal failure, it is a potential source of complication such as: septicemia, hyperglycemia, venous thrombosis and liver disease. There are several hypothesis conceived to explain the liver disease associated to intestinal failure, however the only definite treatment as a potential to reverse the non-cirrhotic liver disease is the small intestine transplantation. Despite indications for intestine transplantation are not entirely defined in literature, the trend is its early indication in high-risk patients, preserving the liver integrity and preventing the eventual need of both liver and intestine transplantations altogether.A introdução da Nutrição Parenteral Total (NPT despertou uma nova esperança para o tratamento da falência intestina (FI associada a Síndrome do Intestino Curto (SIC. No entanto, junto com a NPT e o aumento da sobrevida destes pacientes, novos problemas e perguntas emergiram, assim como novas terapêuticas. Tendo em vista esta realidade emergente, o intuito deste artigo é realizar uma revisão dos conceitos atuais e dos tratamentos disponíveis para pacientes com doença hepática associada a FI.

2017-01-01

Full Text Available La ecología de medios ha generado una reflexión importante de la díada tecnología-sociedad. Sin embargo, a pesar de acuñar un concepto relacio-nado con el medio ambiente, diferentes autores han cuestionado que dicho campo multidisciplinario no haya derivado en ningún aporte importante relacionado con el contexto ambiental. Respecto de la ecología de medios, las tecnologías han causado un impacto definitivo sobre el planeta. No obs-tante, recientes tendencias en la investigación en comunicación conceptúan que este cambio trasciende lo simbólico y se instala en lo material con con-secuencias serias en los ecosistemas, en los seres vivos y en la sostenibilidad del planeta. Utilizando como base los planteamientos del filósofo norue-go Arne Naess, el presente artículo intenta contribuir a subsanar la deuda pendiente que tiene la ecología de medios con el contexto ambiental. Para propiciar esta reflexión, extendemos la metáfora de la ecología de medios a la ecología profunda de medios para a partir de este marco analizar la re-lación entre tecnologías y los aparatos/artefactos asociados a los medios y su relación con la sociedad.

Full Text Available Las redes sociales, como Twitter, se han convertido en plataformas usadas tanto por los cibernautas como por las corporaciones a fin de alcanzar audiencias a un nivel que, hasta hace una década, parecía inimaginable. El periodismo ha sido afectado por esta tendencia, obligando a los periodistas y empresas de comunicación a emplear estas redes sociales. La incidencia de los medios y periodistas en plataformas como Twitter plantea múltiples maneras de presentarse al público. Mientras que los medios enfrentan el reto de prolongar su cierre informativo, los periodistas buscan balancear su vida su perfil profesional y personal en la red. Tras un análisis comparativo de las cuentas de periodistas y medios chilenos en Twitter, se evidencia un problema que nos permitirá estudiar y proponer pautas de acción ante el fenómeno. Así, surgen las siguientes interrogantes: ¿Los medios pueden corporativizar una herramienta social que es esencialmente de naturaleza personal? ¿Un periodista puede informar, brindar su opinión como ciudadano común, en una cuenta de Twitter creada con su perfil profesional? ¿Los perfiles de medios y periodistas pueden coexistir en la misma red social? Las respuestas a estas preguntas conllevan nuevos retos profesionales y éticos que pueden dar cabida a estudios ulteriores.

Os indivíduos foram classificados como normal, sobrepeso/obesidade, de acordo com as medidas do IMC, e como não-obeso com obesidade abdominal, de acordo com as medidas da circunferência da cintura (CC. A pressão arterial sistólica (PAS e diastólica (PAD foi avaliada através de um dispositivo oscilométrico. Regressão logística e curvas ROC foram usadas na análise estatística. RESULTADOS: A prevalência geral de HA foi 11,8% (13,4% em meninos e 10,2% em meninas. A prevalência de HA em meninos e meninas com sobrepeso/obesidade foi 10% e 11,1%, respectivamente. A prevalência de HA em meninos com obesidade abdominal foi 28,6%. Para ambos os sexos, o odds ratio (OR para HA foi mais alto na obesidade abdominal do que no sobrepeso/obesidade geral (4,09 [OR IC95% = 2,57-6,51] versus 1,83 [OR IC95% = 1,83-4,30]. O OR para HA foi mais alto quando sobrepeso/obesidade geral e obesidade abdominal estavam agrupados (OR = 4,35 [OR IC95% = 2,68 -7,05], do que quando identificados como sobrepeso/obesidade geral ou obesidade abdominal apenas (OR = 1,32 [OR IC95% = 0,65- 2,68]. Entretanto, ambos os tipos de obesidade apresentavam baixo poder preditivo na detecção de HA. CONCLUSÃO: Obesidade geral e obesidade abdominal foram associadas com HA; entretanto, a sensibilidade e especificidade dessas variáveis na detecção de HA são baixas em adolescentes brasileiros.BACKGROUND: Obesity is linked to high blood pressure (HBP in childhood. However, the role of fat as a predictor of HBP in adolescents remains unknown. OBJECTIVE: To

Full Text Available Introdução: Os tumores do intestino delgado são raros, de diagnóstico difícil e quando malignos, têm prognóstico ruim. Os linfomas primários representam menos de 2% de todos os tumores gastrointestinais malignos, sendo na sua maioria do subtipo de células B. Casuística: Foi relatado um caso raro de linfoma de intestino delgado em uma paciente do sexo feminino de 77 anos, que procurou atendimento médico com sintomas inespecíficos e um quadro anêmico. Os exames radiológicos foram fundamentais para esclarecimento, diagnóstico e propedêutica. Os marcadores tumorais foram negativos e as provas de atividade inflamatória, positivas. Na internação, a paciente teve piora súbita do quadro clínico, necessitando de cirurgia. No intra-operatório, foi identificado lesão perfurativa em jejuno proximal de aspecto ulcerado com aderências na bexiga e fundo do útero. A paciente não evoluiu bem, falecendo após três dias. A patologia confirmou Linfoma Não Hodgkin Difuso de Grandes Células B, com elevado índice de proliferação celular. Discussão: O diagnóstico radiológico pré-operatório do tumor do intestino delgado só é obtido em um pequeno percentual de pacientes sintomáticos. Estudos por imagem demonstram aspectos morfológicos do tipo infiltrativo, polipóide ou aneurismático. Geralmente, ocorre acometimento circunferencial da alça, com espessamento irregular das pregas, de extensão variável. Conclusão: O objetivo deste estudo foi documentar um raro tumor do intestino delgado do tipo Linfoma Não-Hodgkin Difuso de Grandes Células B, multicêntrico, de difícil diagnóstico e com rápida evolução dos sintomas, que culminaram com quadro de obstrução intestinal aguda, necessitando de cirurgia de emergência. Introduction: Tumors of the small bowel are rare, but when they are malignant they have a poor prognosis. The primary lymphomas represent less than 2% of all malignant gastrointestinal tumors, and the majority

Control of this pest in storehouses is carried out with the massive use of pesticides. With the object of finding an alternative method of control, an electron microscope study was made of the mid intestine of adults and larvae. Detected in the mid intestine of adult. P. truncatus was the presence of a peritrophic membrane. This membrane is formed by an irregular grid composed of various layers which are absent in the mid intestine of the last larval stage of P. truncatus. This indicates that formation of the peritrophic membrane take place mainly during the pupal stage, for which P. truncatus may be controlled biologically by using transgenic plants with the specific information to interfere in the synthesis of this membrane.Prostephanus truncatus (Horn es un insecto plaga del maíz almacenado en México, América Central, parte de América del Sur y se está expandiendo rápidamente en África desde que fue introducido a este continente.

Los pacientes diabéticos y los hospitalizados presentan mayor riesgo de desarrollar nefropatía inducida por medios de contraste que la población general. Objetivo. Establecer el costo-efectividad de los medios de contraste isosmolales e hiposmolales en pacientes con alto riesgo. Materiales and métodos. El análisis se basó en una revisión sistemática de la literatura científica, comparando los efectos nefrotóxicos de los medios isosmolales e hipoosmolales. Se consideraron sólo los costos directos, obtenidos del manual tarifario. Se calcularon las tasas del incremento del costoefectividad, las curvas de eficiencia y de aceptabilidad. Se hicieron análisis univariados de sensibilidad para costos y efectos, así como probabilísticos. Se aplicaron tasas de descuento de 0 y 3 % a losresultados. Se usó como umbral de costo-efectividad por año de vida ganado, el producto interno bruto per cápita. Resultados. Las alternativas con Iopamidol y Iodixanol dominan a las demás porque reducen el riesgo de nefropatía inducida por contraste a un menor costo. La razón del incremento del costo-efectividad del iodixanol comparado con el iopamidol es de US$ 14.660 por año de vida ganado que más que duplica el umbral. Conclusión. El medio de baja osmolalidad, iopamidol, parece ser costo-efectivo comparado con iohexol u otros medios hiposmolares (iopromide, iobitridol, iomeprol, iopentol y ioxilan, en pacientes con alto riesgo de nefropatía inducida por contraste. La elección del medio hiposmolar, depende de la disponibilidad a pagar o del costo por ampolleta.   doi: http://dx.doi.org/10.7705/biomedica.v32i2.367

Dimensiones e indicadores de la calidad informativa en los medios digitales

Full Text Available El actual ecosistema informativo, atravesado por una lógica de mediamorfosis, está generando con avidez el surgimiento de medios digitales y portales informativos que no siguen los procedimientos editoriales formales de los medios convencionales. La crisis de los medios de comunicación tradicionales ha cambiado también nuestra forma de informarnos. Sin embargo, la calidad informativa sigue siendo un factor de discusión al no existir unidad de criterios para su análisis. En este sentido surge la pregunta ¿Cómo evaluar y valorar la calidad informativa de los medios digitales? Este trabajo contribuye a buscar convergencias entre académicos y profesionales de la comunicación sobre las áreas y dimensiones de la calidad informativa de los medios digitales en función de valores objetivos o cuantificables. Para ello se ha realizado una taxonomía de dimensiones de la calidad informativa a partir de la revisión de la literatura científica, para posteriormente someterlo a la evaluación y validación por juicio de 40 expertos, académicos y profesionales de la comunicación, para verificar su fiabilidad. Como resultado, quedaron validadas tres macroáreas de la calidad informativa, contentivas en 21 ámbitos que consideran intrínsecamente un total de 75 dimensiones. Esta investigación propone finalmente un modelo estructurado que permitirá analizar la calidad informativa de los medios digitales, tanto en su fase pre-informativa, catalogadas en el medio-empresa, las características sociolaborales de los trabajadores del medio, así como el producto final y el contenido informativo.

En varios estudios se aconseja que esta no supere los 16-20 cm. H2O. Además de las posibles molestias abdominales, una presión intrabdominal elevada puede tener relación con los problemas de la pared abdominal, como hernias y fugas y tener implicaciones en el transporte peritoneal y el déficit de ultrafiltración. Los objetivos del presente trabajo fueron: conocer los niveles de presión intrabdominal de los enfermos prevalentes en diálisis peritoneal, valorar los factores que influyen en los valores de esta presión y estudiar retrospectivamente la relación entre presión intrabdominal y desarrollo de hernias y fugas. Realizamos un estudio transversal, observacional y retrospectivo de valoración de la presión intrabdominal en los enfermos prevalentes, estables, con más de tres meses en diálisis peritoneal. La presión intrabdominal se midió mediante el método descrito por Durand: paciente en decúbito supino, con el volumen peritoneal diurno. La presión intrabdominal final es la media entre las mediciones realizadas durante la inspiración y la espiración, se expresa en cm. de H2O, y se especifica el volumen drenado. También se realizó una medida en sedestación y en bipedestación. Se estudiaron 34 pacientes, 66% varones, edad media de 61.2±14 años, 3 con poliquistosis renal, un índice de comorbilidad de Charlson medio de 7,9, un índice de masa corporal medio de 27.4±4.2 y un tiempo medio en DP de 21±12 meses.

Un 32% de los pacientes tenían antecedentes de cirugía abdominal y un 5% de hernias, reparadas antes del inicio de la diálisis peritoneal. La media de presión intrabdominal en decúbito fue de 17.5±4.1 cm. de H2O, y un volumen medio por superficie corporal de 1141

Intra-abdominal hypertension and abdominal compartment syndrome in association with ruptured abdominal aortic aneurysm in the endovascular era: vigilance remains critical.

Science.gov (United States)

Bozeman, Matthew C; Ross, Charles B

2012-01-01

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are common complications of ruptured abdominal aortoiliac aneurysms (rAAAs) and other abdominal vascular catastrophes even in the age of endovascular therapy. Morbidity and mortality due to systemic inflammatory response syndrome (SIRS) and multiple organ failure (MOF) are significant. Recognition and management of IAH are key critical care measures which may decrease morbidity and improve survival in these vascular patients. Two strategies have been utilized: expectant management with prompt decompressive laparotomy upon diagnosis of threshold levels of IAH versus prophylactic, delayed abdominal closure based upon clinical parameters at the time of initial repair. Competent management of the abdominal wound with preservation of abdominal domain is also an important component of the care of these patients. In this review, we describe published experience with IAH and ACS complicating abdominal vascular catastrophes, experience with ACS complicating endovascular repair of rAAAs, and techniques for management of the abdominal wound. Vigilance and appropriate management of IAH and ACS remains critically important in decreasing morbidity and optimizing survival following catastrophic intra-abdominal vascular events.

Observou-se a presença de células vacuoladas do duodeno ao jejuno médio no recém-nascido, preenchidas por material absorvido após a ingestão de colostro. Foram verificadas mudanças nas características morfológicas aos três dias de idade, com o início da detecção de reação da fosfatase ácida em lisossomos, indicando ação enzimática sobre o material absorvido. A morfologia aos três dias de idade pode representar o diferente estádio de maturação das células epiteliais do intestino delgado de bezerros, indicando que o processo depende das características da primeira geração de células desta região do intestino.The objective of this study was to study the morphology and the localization of acid phosphatase at calves anterior small intestine, from birth to intestinal closure. Fifteen male dairy calves were used in this study, which were aged: unsuckled neonatal, three hours after colostrum ingestion and three days old. Vacuolated cells from duodenum to medium jejunum could be found in the newborn calf, which have shown absorbed material after colostrum ingestion. Changes at the morphological characteristics and the initiation of phosphatase acid reaction in lysosomes were observed in calves aged three days old. The three days old morphology can represent a different phase of epithelium cells maturation of calves small intestine indicating that the absorption process is dependent of the first generation of cells from this intestinal region.

Abdominal trauma

International Nuclear Information System (INIS)

Giordany, B.R.

1985-01-01

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

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

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

2013-01-01

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.

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

Child with Abdominal Pain.

Science.gov (United States)

Iyer, Rajalakshmi; Nallasamy, Karthi

2018-01-01

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

Se incluyeron muestras de intestino grueso de 20 cerdos adultos, para el aislamiento de bacterias lácticas (BAL. La caracterización de los parámetros bioquímicos-fisiológicos de las BAL contemplo la evaluación del pH del fermento, determinación de ácidos orgánicos por HPLC y detección de isómeros de ácido láctico. Los procedimientos microbiológicos evaluaron la capacidad de inhibición del crecimiento de patógenos y la actividad antagónica del probiótico vs antibiótico con su interacción competitiva. Se utilizaron pruebas API CHL 50 para la identificación de las BAL que se complementaron con la producción de gas, actividad de catalasa y viabilidad a diferentes concentraciones de sales biliares y temperaturas. Resultados. El plan de análisis permitió seleccionar dos aislados que se identificaron como: Lactobacillus plantarum 1 H1 y Lb. plantarum 1 H2. Las pruebas microbiológicas evidenciaron que las BAL seleccionadas inhibieron principalmente los enteropatógenos: Escherichia coli, Salmonella typhimurium y Clostridium perfringens. Las pruebas bioquímicas fueron compatibles con el género Lactobacillus, mostrando el siguiente perfil: Catalasa negativas; no productoras de gas; productoras de isómeros DL; resistentes a sales biliares y pH óptimo de crecimiento 3.5 a 38oC. Conclusiones. Los dos aislados de Lactobacillus plantarum 1 reunieron las características para el uso potencial como probióticos. Se recomienda su uso como complemento de terapias con antibióticos y en la elaboración de inóculos para aplicación en raciones alimenticias de lechones destetos, sin embargo, estudios complementarios se requieren para evaluar el efecto directo del probiótico como sustituto del uso de antibióticos in vivo.

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

Don't Forget the Abdominal Wall: Imaging Spectrum of Abdominal Wall Injuries after Nonpenetrating Trauma.

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

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

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

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)

Animal models have suggested that maternal diet quality may reduce offspring obesity risk regardless of maternal body weight; however, evidence from human studies is scarce. The aim of this study was to evaluate associations between adherence to the Mediterranean diet (MD) during pregnancy and childhood overweight and abdominal obesity risk at 4 years of age. We analysed 1827 mother-child pairs from the Spanish 'Infancia y Medio Ambiente' cohort study, recruited between 2003 and 2008. Diet was assessed during pregnancy using a food frequency questionnaire and MD adherence by the relative Mediterranean diet score (rMED). Overweight (including obesity) was defined as an age-specific and sex-specific body mass index ≥85th percentile (World Health Organization referent), and abdominal obesity as a waist circumference (WC) >90th percentile. Multivariate adjusted linear and logistic regression models were used to evaluate associations between pregnancy rMED and offspring overweight and abdominal obesity. There was no association between rMED and body mass index z-score, whereas there was a significant association between higher adherence to MD and lower WC (β of high vs. low rMED: -0.62 cm; 95% confidence interval: -1.10, -0.14 cm, P for trend = 0.009). Pregnancy adherence to the MD was not associated with childhood overweight risk, but it was associated with lower WC, a marker of abdominal obesity. © 2016 World Obesity Federation.

Chronic Abdominal Wall Pain.

Science.gov (United States)

Koop, Herbert; Koprdova, Simona; Schürmann, Christine

2016-01-29

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

Torsion of abdominal appendages presenting with acute abdominal pain

International Nuclear Information System (INIS)

Al-Jaberi, Tareq M.; Gharabeih, Kamal I.; Yaghan, Rami J.

2000-01-01

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

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

LENUS (Irish Health Repository)

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.

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

[Differential diagnosis of abdominal pain].

Science.gov (United States)

Frei, Pascal

2015-09-02

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.

2001-01-01

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.)

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

Hanna, Dominique; Cloutier, Richard; Lapointe, Roch; Desgagné, Antoine

2004-01-01

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

Full Text Available El consumo de medios de comunicación ha sido estudiado asiduamente, y existen numerosas investigaciones focalizadas  en el consumo que hacen niños y adolescentes de medios como la televisión y, en los últimos años, de medios interactivos e Internet. Esta línea de estudio se justifica al ser este público el más vulnerable ante los efectos perniciosos que cada medio pueda conllevar. Sin embargo, son escasas las investigaciones en jóvenes que acaban de alcanzar la mayoría de edad, que están empezando estudios universitarios y que, amparados en el Espacio Europeo de Educación Superior, se verán obligados a enfrentarse con los medios de comunicación no sólo como instrumentos de ocio, sino también como herramientas de trabajo/estudio.Esta investigación analiza qué medios consumen y por qué los consumen los jóvenes universitarios, con el objetivo de determinar qué carencias tienen en competencias mediáticas y establecer futuras líneas de actuación educativa. Para ello, se ha realizado una encuesta a 262 alumnos de primero del Grado de Publicidad y RR.PP. de la Universidad de Alicante. Los resultados apuntan que el consumo de los medios es mayoritariamente por ocio y se hace poco uso de ellos como herramienta de formación. Por este motivo se proponen una serie de actuaciones encaminadas a mejorar sus habilidades y competencias en otros usos.

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.

We report the case of a 15-year-old boy suffering from progressive dyspnea on exertion and painful abdominal protrusion. Final diagnosis of intra-abdominal tuberculosis (TB), including lymphadenopathy and abdominal abscess formation, was made following elective laparotomy. This type of disease is a rare manifestation of extrapulmonary tuberculosis. The imaging findings in unenhanced and contrast-enhanced MRI and laparoscopic images are presented. Differential diagnosis of abdominal abscess formation and other fungal or bacteriological infections, as well as the imaging findings of this type of lesion, are discussed. This case demonstrates that atypical manifestation of TB may remain unrecognized; thus, awareness of this kind of manifestation of tuberculosis may prevent patients from being subjected to inappropriate therapies.

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.

Abdominal epilepsy (AE) is a rather uncommon clinical entity in children that might create diagnostic confusion especially when it lacks the typical manifestations of an epileptic seizure. We report the case of a young boy having apparently unexplained episodes of paroxysmal abdominal symptoms with no other suggestion of an underlying epileptic disorder. The case also explains how the clinical presentation can be misleading unless a high index of suspicion is maintained to reach the ultimate diagnosis. (author)

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

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

Full Text Available BACKGROUND: Small intestine transplantation has been accepted worldwide to treat complex cases of intestinal failure. Canine intestinal transplantation model is important in training the surgical technique and to study the complications of this procedure. Systemic graft venous drainage is frequently performed in clinic, although the consequences of this partial meso-caval shunt have not been studied in detail. AIM: To describe the surgical technique and clinical outcome of a canine intestinal transplantation model using mesenteric-caval graft drainage. METHOD: Adult mongrel dogs from University of São Paulo Animal Facility, São Paulo, SP, Brazil, were used as donors and recipients in ten consecutives orthotopic intestinal transplantation with mesenteric-caval venous drainage. Clinical examination and body weight measurement were performed daily in all animals. Necropsy was performed in animals presenting moribund state (lethargic posture, diarrhea and loss of over 35% of body weight to determine cause of death and histological changes. RESULTS: Three recipients died before day 2 from technical complications and were excluded from the experiment. The remaining seven animals developed signs of graft rejection with onset on days 3-4 and died or were sacrificed presenting severe graft rejection between days 7-9. Necropsy and histology of the graft confirmed the diagnosis of severe acute cellular rejection. CONCLUSION: Small intestine transplantation with systemic drainage in dogs courses with analogous and lethal outcome between postoperative day 7 to 9 due to strong graft rejection. This model serves as an excellent pre-clinical model to study the main complications related to this transplantation.RACIONAL: O transplante de intestino delgado é atualmente indicado para tratar casos complexos de falência entérica.

Functional abdominal pain.

Science.gov (United States)

Grover, Madhusudan; Drossman, Douglas A

2010-10-01

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

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. Conclusions: US

No entanto, para o nosso conhecimento, a prevalência dessa grave vasculite em uma população pediátrica com lúpus ainda não foi estudada. Portanto, dados de 28 anos consecutivos foram revisados e incluídos 5.508 pacientes em seguimento no Hospital da Faculdade de Medicina da Univesidade de São Paulo (FMUSP. Identificamos 279 (5,1% casos que preencheram critérios de classificação diagnóstica do American College of Rheumatology para lúpus eritematoso sistêmico (LES e um (0,4% desses apresentou VML. Este paciente recebeu diagnóstico de LES aos 11 anos de idade. Aos 13 anos foi hospitalizado com dor abdominal difusa e aguda, náuseas, vômitos biliosos, distensão e rigidez abdominal, com descompressão brusca positiva. O paciente foi prontamente submetido à laparotomia exploradora, identificando isquemia intestinal segmentar, com edema de parede intestinal e aderências. Foi realizada ressecção parcial de intestino delgado, com lise das aderências e pulsoterapia com metilprednisolona. A análise histopatológica identificou arterite de vasos mesentéricos. Após 13 dias, apresentou recorrência de dor abdominal difusa intensa, sendo novamente submetido à laparotomia exploradora, identificando obstrução em intestino delgado por aderências, com gangrena intestinal. Nova ressecção intestinal foi realizada, além de pulsoterapia com metilprednisolona e infusão de imunoglobulina. Portanto, VML é uma rara e grave manifestação abdominal na população com lúpus pediátrico, e pode ser a única manifestação de atividade da doença. Além disso, este estudo reforça a importância do diagnóstico precoce e do tratamento imediato.

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.

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.

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

Full Text Available Las investigaciones han demostrado que los entrenadores aprenden, no sólo a través de los programas educativos, sino también a través de otros medios de aprendizaje informales que se producen en charlas con otros compañeros, mentores, observación de otros entrenadores, libros, Internet e incluso experiencias pasadas como jugador. ,Por todo ello, el objeto del presente artículo es conocer los medios formativos más utilizados por dieciséis entrenadores expertos en baloncesto, así como exponer detalladamente cada uno de ellos para su posible transferencia hacia otros entrenadores. Para la realización del estudio, se ha utilizado una metodología cualitativa y la técnica de entrevista semiestructurada en la cual se ha entrevistado a dieciséisentrenadores expertos en baloncesto. Los resultados muestran que la educación formal (cursos federativos de los entrenadores tiene un volumen claramente inferior a los medios informales. Además, estos medios informales tienen mayor relevancia en los entrenadores al tratarse de contenidos mucho más específicos. Entre estos medios destacan, principalmente, el aprendizaje situado (experiencias diarias como entrenador, la reflexión práctica, el mentoring, el aprendizaje compartido (charlas y observación de otros entrenadores, etc., así como en menor relevancia, las comunidades de práctica, las experiencias de la etapa como jugador y el aprendizaje no situado. Estos resultados nos hacen reflexionar sobre la reestructuración de los actuales programas formativos en los entrenadores, los cuales claramente tienen que ser más específicos, cercanos a la realidad y a las circunstancias del entrenador.

Abdominal emergencies in pediatrics.

Coca Robinot, D; Liébana de Rojas, C; Aguirre Pascual, E

2016-05-01

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

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.

Blunt abdominal trauma in children.

Science.gov (United States)

Schonfeld, Deborah; Lee, Lois K

2012-06-01

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

Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and <50% of the thickness differences in all muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents. Copyright © 2014 Elsevier Ltd. All rights reserved.

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

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

Science.gov (United States)

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

2016-04-01

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

CT of abdominal abscesses

International Nuclear Information System (INIS)

Korobkin, M.T.

1987-01-01

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

Adult abdominal hernias.

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.

Full Text Available Objective: To review the available evidence on the role of T-lymphocytes and mast cells in the etiopathogenesis of Irritable Bowel Syndrome. Methods: Bibliographic retrieval on PubMed including the terms "Irritable Bowel Syndrome, "Immune System", "T-Lymphocytes" and "Mast Cells". Results: Twenty-five case-control studies and one randomized controlled trial were retrieved. Noteworthy in the blood is the increase in activated T cells destined to migrate to the bowel in these patients. A high frequency of T-lymphocytes is described in the intestinal mucosa, although the study findings are, at times, contradictory. An evident increase in mast cells (and in their activity between the terminal ileum and descending colon is also observed. Conclusions: The heterogeneity of diagnostic criteria and experimentation methods could account for some of the differences in the results found in the selected research. There are indications that give reason to believe these patients have "low-grade intestinal inflammation", and the increase in T-lymphocytes and mast cells has been associated with disorders found in IBS such as the communication between the intestine and the nervous system, the increase in intestinal permeability and changes in the microbiota.Objetivo: Revisar la evidencia disponible sobre el papel de los linfocitos T y mastocitos en la etiopatogenia del Síndrome del Intestino Irritable. de las vías biliares.

Full Text Available Appendecitis is one of the most frequent surgeries. Inflammation of appendix may be due to variable causes such as fecalit, hypertrophy of Peyer’s plaques, seeds of fruits and parasites. In this study we presented an uncommon type of appendicitis which occurred after abdominal blunt trauma. In this article three children present who involved acute appendicitis after blunt abdominal trauma. These patients were 2 boys (5 and 6-year-old and one girl (8-year-old who after blunt abdominal trauma admitted to the hospital with abdominal pain and symptoms of acute abdomen and appendectomy had been done for them.Trauma can induce intramural hematoma at appendix process and may cause appendicitis. Therefore, physicians should be aware of appendicitis after blunt abdominal trauma

Full Text Available Effects of thalamic nuclei damage and related white matter tracts on memory performance are still debated. This is particularly evident for the medio-dorsal thalamus which has been less clear in predicting amnesia than anterior thalamus changes. The current study addresses this issue by assessing 7 thalamic stroke patients with consistent unilateral lesions focal to the left medio-dorsal nuclei for immediate and delayed memory performance on standard visual and verbal tests of anterograde memory, and over the long-term (> 24 hrs on an object-location associative memory task. Thalamic patients showed selective impairment to delayed recall, but intact recognition memory. Patients also showed accelerated forgetting of contextual information after a 24 hour delay, compared to controls. Importantly, the mammillothalamic tract was intact in all patients, which suggests a role for the medio-dorsal nuclei in recall and early consolidation memory processes.

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

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

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

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.

Full Text Available OBJECTIVE AND METHODS: Screening for abdominal aortic aneurysms may be useful to decrease mortality related to rupture. We conducted a study to assess the prevalence of abdominal aortic aneurysms in southern Brazil and to define risk factors associated with high prevalence of this disorder. The screening was conducted using abdominal ultrasound. Three groups were studied: Group 1 - cardiology clinic patients; Group 2 - individuals with severe ischemic disease and previous coronary surgery, or important lesions on cardiac catheterism; Group 3 - individuals without cardiac disease selected from the general population. All individuals were male and older than 54 years of age. The ultrasonographic diagnosis of aneurysm was based on an anteroposterior abdominal aorta diameter of 3 cm, or on an abdominal aorta diameter 0.5 cm greater than that of the supra-renal aorta. RESULTS: A total of 2.281 people were screened for abdominal aortic aneurysms in all groups: Group 1 - 768 individuals, Group 2 - 501 individuals, and Group 3 - 1012 individuals. The prevalence of aneurysms was 4.3%, 6.8% and 1.7%, respectively. Age and cigarette smoking were significantly associated with increased prevalence of aneurysms, as was the diagnosis of peripheral artery disease. DISCUSSION: We concluded that screening may be an important tool to prevent the mortality associated with abdominal aortic aneurysms surgery. Additionally, the cost of screening can be decreased if only individuals presenting significant risk factors, such as coronary and peripheral artery disease, smokers and relatives of aneurysm patients, are examined.OBJETIVO E MÉTODOS: O rastreamento de aneurisma da aorta abdominal infra-renal é importante pois pode diminuir a mortalidade relacionada à ruptura.

La corriente política y social que en todo el mundo tiende a una mayor participación ciudadana en la gobernanza de las instituciones se materializó en el Derecho comunitario, entre otras cosas, en la inclusión de la figura de la iniciativa ciudadana, en virtud del Tratado de Lisboa, como un derecho más dentro del abanico del estatuto de la ciudadanía europea.  Los textos normativos comunitarios han previsto un importante papel para los medios digitales, tanto para facilitar la información como la participación de los ciudadanos. Habiendo transcurrido ya unos tres años desde el comienzo de la posibilidad de presentar iniciativas ciudadanas y habiéndose promovido ya en la práctica unas cincuenta, se posee ya perspectiva suficiente para valorar si aquellas expectativas eran fundadas o no. Tras el estudio pertinente, hemos podido corroborar cómo los medios digitales han resultado esenciales para alcanzar los fines para los que se pensó la iniciativa ciudadana, tanto en el sentido de servir de altavoz de las iniciativas promovidas, como en el de facilitar las recogidas de apoyos mediante páginas web. Incluso, parece que la práctica demuestra que hoy en día ya sería imposible, por falta de tiempo y medios de todo tipo, alcanzar las cifras de apoyo requeridas por las normas pertinentes sobre la iniciativa ciudadana, en los plazos previstos, si no es con ayuda de los medios digitales.

In order to compare three radiographic techniques -pneumocolon, barium enema and double contrast- in the large intestine of the dog, three radiographic series in ventrodorsal and right lateral projections were taken. Six healthy adult dogs of both sexes with an approximate weight between 5 to 10 kg were used. Three enemas were administered 24, 12 and 2 hrs. before the series of radiographs were taken. Then dogs were anaesthetized with sodium tiopental (20 mg/kg iv) and the contrast media were introduced. Pneumocolon was carried out in the first series introducing air (20 cc/kg) in the large intestine through a Foley rectal catheter. Radiographs were taken in both projections, after 5 and 15min. respectively. Barium enema was performed in the second series introducing barium sulfate (18%) in the large intestine through a Foley rectal catheter (25 cc/kg); 5 and 15 min. later, the radiographs were taken. In the third series -double contrast- the barium sulfate, which was obtained from each dog using a catheter, was substituted by a volume of air equal to that obtained from the contrast medium. Later the radiographs were taken in both projections. The radiographic plates of each series were analized comparing the characteristics of: radiographic density, outline and volume. With the pneumocolon barium enema and double contrast, the radiographic density was, in most cases, low, high and inter-mediate respectively. The radiographic outline was, in most cases, regular for the three techniques. Thee radiographic volume was similar in all of the series. From the results obtained, it is concluded that double contrast best outlines the intestinal mucosa and more information can be obtained from it [Spanish] Con la finalidad de comparar tres tecnicas radiograficas del intestino grueso del perro -neumocolon, enema baritado y doble contraste-, se tomaron tres series radiograficas en proyeccion ventrodorsal y lateral derecha en 6 perros adultos, de 5 a 10 kg de peso, que

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

Full Text Available La lesión humana al medio ambiente, adquiere una dimensión inusitada en el capitalismo, este modo de producción tiene una propensión intrínseca al crecimiento incesante. No es esperable en lo inmediato la desaparición del capitalismo, por lo que es improbable un cambio radical en esas condiciones desfavorables. Sin embargo, es imperioso proteger la naturaleza pues el daño causado tiende a ser irreversible. Es un imperativo ético y fácticamente puede aprovecharse la adaptabilidad de la economía capitalista. El modelo más famoso de tributo para proteger el medio ambiente es el de los impuestos pigouvianos que responden a la idea de que el impuesto a quien contamine constituye para éste un costo que compensa el “costo social” que supone el daño ambiental. Esta función es incompatible con preservar a todo trance el medio ambiente: su estructura de “pago por daño” convierte al medio ambiente en una mercancía más, cuyo precio es el impuesto. No impide el desarrollo de las actividades dañinas, el carácter monopólico u oligopólico de las grandes empresas contaminantes permite compensar el costo de estos impuestos con aumentos de precios. En consecuencia, sólo la prohibición de actividades es una medida de real protección del medio ambiente.

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

Full Text Available La exposición inadecuada en los medios de comunicación sobre suicidios puede producir un efecto contagio o efecto Werther , mientras que determinadas características adecuadas pueden tener un efecto protector o efecto Papageno . Por tanto, los medios de comunicación pueden contribuir a la prevención del suicidio. Por ello, la OMS ha elaborado tres documen- tos con una serie de recomendaciones dirigidas a los profesionales de los medios de comunicación, para el tratamiento de las noticias relacionadas con el suicidio. Sin embargo, solo se ha traducido al español el primero, ambos tienen solapamientos y poseen una estructura diferente. Esto supone que los profesionales de los medios de comunicación de habla hispana en general, y de España en particular, difícilmente pueden tener un acceso a estas recomendaciones de la OMS de una forma clara y concisa. El objetivo de este trabajo fue la elaboración y provisión de un texto único y sintético que recogiera las recomendaciones de estos documentos. Para su creación se siguió un procedimiento formal y estructurado, que aunó criterios científicos y lingüísticos. El texto final contiene las recomendaciones agrupadas en tres categorías: “qué hacer”, “qué no hacer” y “otras recomendaciones”. Este documento puede ser de gran utilidad para los profesionales de los medios de comunicación, para actividades formativas de difusión de tales recomen- daciones con finalidad preventiva y para la investigación.

Abdominal angina

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

Gerhards, H.; Klein, H.J.; Offeney, F.

1990-01-01

A diagnostic approach based on clinical and radiographic examinations for evaluation of young foals and small ponies with acute abdominal discomfort is presented. Standing right to left lateral abdominal radiographs were taken of 54 foals and 6 ponies using a previously described technique. Interpretation of the radiographs was in conjuction with all clinical and laboratory findings and patient management. Using this approach, the site and cause of acute abdominal discomfort could be diagnosed accurately in 55 of 60 (91%) patients as confirmed by clinical, surgical or PM findings. Typical radiographs and photographs taken at surgery or at PM examination are presented. Typical radiographic findings, their interpretation and possible underlying gastrointestinal diseases are listed. It is concluded that the incorporation of standing lateral abdominal radiography in the clinical evaluation of foals and ponies with acute abdominal diseases gives findings of high diagnostic significance and should contribute to clinical decision-making, and that abdominal radiography can replace data from rectal palpation in foals and ponies

ômago, duodeno, pancreas, fígado, baço, intestino delgado, e colon. Uma prótese vascular foi interposta entre a veia cava infra e supra-hepática. Efeitos hemodinâmicos foram avaliados por meio de um cateter de Swan-Ganz catheter e Doppler ultrassônico. As variáveis dependentes de oxigênio, e o metabolismo da glicose e lactato foram avaliados durante todo o experimento. RESULTADOS: A evisceração abdominal esteve associada a uma redução significativa do débito cardiaco e da pressão arterial média (57% and 14%, respectivamente. Duas horas após a reconstrução vascular da veia cava inferior observou-se uma redução significativa do pH e da glicose arterial. O consumo de oxigênio se manteve inalterado nas primeiras duas horas do experimento, com um significativo aumento dos níveis séricos de lactato (1.4±0.3 vs. 7.6±0.4, p<0.05. Três animais morreram antes de 180 minutos após a reperfusão. CONCLUSÃO: A evisceração abdominal total esteve associada com graves repercussões hemodinâmicas e metabólicas sistêmicas. Estas graves alterações hemodinâmicas estam associadas, provavelmente, a combinação de vários fatores incluindo: acidose metabólica, hiperlactemia, hipoglicemia e redução do volume de sangue circulante. A cuidadosa monitorização hemodinâmica e metabólica deve ser realizada durante o MVTx experimental com a finalidade de promover um aumento das taxas de sobrevida deste complexo procedimento.

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.

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

Acute abdominal pain in children is a common cause for referral to the emergency room and for subsequent hospitalization to pediatric medical or surgical departments. There are rare occasions when the abdominal pain is derived from extra-abdominal organs or systems. The aim of the present study was to establish the most common extra-abdominal causes of acute abdominal pain. The notes of all children (1 month-14 years of age) examined for acute abdominal pain in the Accident and Emergency (A&E) Department of Alexandroupolis District University Hospital in January 2001-December 2005 were analyzed retrospectively. Demographic data, clinical signs and symptoms, and laboratory findings were recorded, as well as the final diagnosis and outcome. Of a total number of 28 124 children who were brought to the A&E department, in 1731 the main complaint was acute abdominal pain. In 51 children their symptoms had an extra-abdominal cause, the most frequent being pneumonia (n = 15), tonsillitis (n = 10), otitis media (n = 9), and acute leukemia (n = 5). Both abdominal and extra-abdominal causes should be considered by a pediatrician who is confronted with a child with acute abdominal pain.

Automated segmentation and recognition of abdominal wall muscles in X-ray torso CT images and its application in abdominal CAD

The information of abdominal wall is very important for the planning of surgical operation and abdominal organ recognition. In research fields of computer assisted radiology and surgery and computer-aided diagnosis, the segmentation and recognition of the abdominal wall muscles in CT images is a necessary pre-processing step. Due to the complexity of the abdominal wall structure and indistinctive in CT images, the automated segmentation of abdominal wall muscles is a difficult issue and has not been solved completely. We propose an approach to segment the abdominal wall muscles and divide it into three categories (front abdominal muscles including rectus abdominis; left and right side abdominal muscles including external oblique, internal oblique and transversus abdominis muscles) automatically. The approach, first, makes an initial classification of bone, fat, and muscles and organs based on the CT number. Then a layer structure is generated to describe the 3-D anatomical structures of human torso by stretching the torso region onto a thin-plate for easy recognition. The abdominal wall muscles are recognized on the layer structures using the spatial relations to the skeletal structure and CT numbers. Finally, the recognized regions are mapped back to the 3-D CT images using an inverse transformation of the stretching process. This method is applied to 20 cases of torso CT images and evaluations are based on visual comparison of the recognition results and the original CT images by an expert in anatomy. The results show that our approach can segment and recognize abdominal wall muscle regions effectively. (orig.)

[Clinical Approach to Abdominal Pain as Functional Origin].

Science.gov (United States)

Ryu, Han Seung; Choi, Suck Chei

2018-02-25

Abdominal pain is a common symptom that patients refer to a hospital. Organic causes should be differentiated in patients with abdominal pain and treatment should be administered in accordance with the causes. A meticulous history taking and physical examination are highly useful in making a diagnosis, and blood tests, imaging modalities, and endoscopy are useful for confirming diagnosis. However, in many cases, patients have functional disorders with no obvious abnormal findings obtained even if many diagnostic tests are performed. Patients with functional disorders usually complain the vague abdominal pain located in the center and other portions of the abdominal area. Although the most representative disease is irritable bowel syndrome, functional abdominal pain syndrome is currently researched as a new disease entity of functional abdominal pain. As various receptors related to functional abdominal pain have been discovered, drugs associated with those receptors are used to treat the disorders, and additional new drugs are vigorously developed. In addition, medical therapy with pharmacological or non-pharmacological psychiatric treatment is effective for treating functional abdominal pain.

Si bien se presentan a primera vista como enfoques antagónicos, puesto que mientras que la semiología se centraba en el contenido ideológico de los mensajes, la ecología de los medios despreciaba el contenido para reivindicar la importancia del medio, el artículo pretende crear un diálogo entre dos de los máximos representantes de ambas teorías: el francés Roland Barthes y el canadiense Marshall McLuhan. La hipótesis del artículo es que el desarrollo de una semiótica (aplicada de las interfaces, inspirada en los planteamientos de Umberto Eco, permitiría encontrar un punto de encuentro entre ambas tradiciones teóricas y, desde ahí, desplegar un análisis más completo de las actuales transformaciones que se están produciendo en la ecología de los medios.

The aim of this study was to compare the effect of diet and an abdominal resistance training program to diet alone on abdominal subcutaneous fat thickness and waist circumference of overweight and obese women. This randomized clinical trial included 40 overweight and obese women randomly divided into 2 groups: diet only and diet combined with 12 weeks of abdominal resistance training. Waist and hip circumferences and abdominal skin folds of the subjects were measured at the beginning and 12 weeks after the interventions. In addition, abdominal subcutaneous fat thickness of the subjects was measured using ultrasonography. Percentage body fat and lean body mass of all the subjects were also measured using a bioelectric impedance device. After 12 weeks of intervention, the weight of participants in both groups decreased; but the difference between the 2 groups was not significant (P = .45). Similarly, other variables including abdominal subcutaneous fat, waist circumference, hip circumference, body mass index, body fat percentage, and skin fold thickness were reduced in both groups; but there were no significant differences between the groups. This study found that abdominal resistance training besides diet did not reduce abdominal subcutaneous fat thickness compared to diet alone in overweight or obese women.

Full Text Available El comportamiento antisocial o inadaptado viene determinado por diversas variables, tanto individuales como contextuales, que pueden actuar como factores de riesgo. Uno de estos factores es el uso de los medios de comunicación electrónicos, especialmente de las más nuevas tecnologías, aunque diversos estudios aseveran que este consumo no ejerce una responsabilidad exclusiva en la adquisición de conductas antisociales por parte de los adolescentes. Utilizando una muestra de 331 jóvenes de ambos sexos, y con edades que oscilan entre los 14 a 20 años, este estudio pretende, por un lado, y a través del modelo de redes neuronales, comprobar el poder predictivo de las variables de personalidad, motivacionales y de consumo de medios electrónicos en la conformación de conductas antisociales y, por otro lado, identificar el rol que cada variable tiene en la construcción del modelo que permita predecir los actos antisociales.

Economics of abdominal wall reconstruction.

Science.gov (United States)

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.

Abdominal compartment syndrome (ACS) is defined as an increased intra-abdominal pressure with adverse physiologic consequences. Abdominal compartment syndrome caused by perforated peptic ulcer is rare owing to early diagnosis and management. Delayed recognition of perforated peptic ulcer with pneumoperitoneum, bowel distension, and decreased abdominal wall compliance can make up a vicious circle and lead to ACS. We report a case of perforated peptic ulcer associated with ACS. A 74-year-old man with old stroke and dementia history was found to have distended abdomen, edema of bilateral legs, and cyanosis. Laboratory tests revealed deterioration of liver and kidney function. Abdominal compartment syndrome was suspected, and image study was arranged to find the cause. The study showed pneumoperitoneum, contrast stasis in heart with decreased caliber of vessels below the abdominal aortic level, and diffuse lymphedema at the abdominal walls. Emergent laparotomy was performed. Perforated peptic ulcer was noted and the gastrorrhaphy was done. The symptoms, and liver and kidney function improved right after emergent operation.

Obesity is a worldwide health problem which is associated with a lot of complications. One of these comorbidities is the metabolic syndrome that is in correlation with abdominal fat thickness and waist circumference. Various methods were used to reduce abdominal fat thickness such as liposuction. A noninvasive method is the topical agent. In this study, we investigated the effectiveness of Arnebia euchroma (AE) ointment on the abdominal fat thickness. This study was a double-blind clinical trial which was done at the endocrinology clinic in Khorshid Hospital, Isfahan, Iran, in 2014. After explaining the procedure and obtaining informed consent, the candidates were randomly divided into the case and control groups. The participants of the case and control groups applied AE ointment or placebo for 6 weeks on their abdominal area. Body mass index, waist and buttock circumference, and abdominal fat thickness were measured in both case and control groups at their first visit and then at the next 2, 4, and 6 weeks. We used t -test for comparing parametric variables between groups, paired t -test for changes from baseline to final, and repeated measure ANOVA for changes at different steps. Sixty female candidates participated in this study (thirty in each group). Ten patients left the study and fifty participants finished the trial. At the end of the study, participants had a significant weight loss (2.96 ± 1.6 kg, P Abdominal circumference also decreased significantly in the participants (11.3 ± 6.7 cm, P abdominal fat thickness decreased significantly in the participants (2.3 ± 1.1 cm, P abdominal fat thickness as well as the waist circumference without causing any side effect.

AE is an infrequent syndrome with paroxystic episodes of abdominal pain, awareness disturbance, EEG abnormalities and positive results with the introduction of antiepileptic drugs. We present one 6 year-old girl who had short episodes of abdominal pain since the age of 4. The pain was followed by cry, fear and occasionally secondary generalization. MRI showed tumor in the left temporal region. As a differential diagnosis, we report a 10 year-old boy who had long episodes of abdominal pain accompanied by blurring of vision, vertigo, gait ataxia, dysarthria, acroparesthesias and vomiting. He received the diagnosis of basilar migraine. In our opinion, AE is part of a large group (partial epilepsies and does not require a special classification. Pediatric neurologists must be aware of these two entities that may cause abdominal pain.Episódios recorrentes de dor abdominal são freqüentes na infância e entre as causas neurológicas há migrânea e epilepsia abdominal (EA.

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

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

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.

El presente trabajo, basado en dos investigaciones de tipo cualitativo, una en Argentina y otra en Ecuador, analiza algunas experiencias concretas en este campo. El marco teórico de referencia se inscribe en la larga tradición de estudios latinoamericanos en torno a la comunicación popular para el cambio social, integrado también con aportes recientes de estudios europeos. El objetivo de las indagaciones era dar cuenta de la articulación comunidades-medios, intentando mostrar la existencia de vínculos recíprocos entre organización social y generación de contenidos. El análisis de los resultados evidencia que la participación directa en la fundación, gestión y sostenibilidad de estos medios por parte de la comunidad repercute en la generación de contenidos orgánicos a sus intereses y necesidades –normalmente desatendidos por los medios públicos y comerciales– y también en una mayor pluralidad y diversidad de la oferta mediática. Además, los resultados permiten avizorar que los medios populares, alternativos y comunitarios son espacios fundamentales para la democratización de la comunicación y para la construcción de una ciudadanía comunicativa. Un desafío que se desprende de las investigaciones es la necesidad de consolidar redes transnacionales para una acción concertada en el plano del orden global de la comunicación mediática, pudiendo medir su potencial incidencia en la agenda pública.

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

International Nuclear Information System (INIS)

Rosen, Max P.; Siewert, Bettina; Bromberg, Rebecca; Raptopoulos, Vassilios; Sands, Daniel Z.; Edlow, Jonathan

2003-01-01

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.)

Recent advances in the management of abdominal compartment syndrome

International Nuclear Information System (INIS)

Saleem, T.B.; Ahmed, I.

2004-01-01

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

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

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

Treatment strategy for ruptured abdominal aortic aneurysms.

Davidovic, L

2014-07-01

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

Full Text Available Publications of recent years do not reflect the regional dynamics of hospitalization of patients with acute surgical pathology of the abdominal cavity and anterior abdominal wall. Goal – to determine the volume of hospitalizations and treatment of patients with acute surgical pathology of the abdominal and anterior abdominal wall in the Kuzbass in the dynamics from 1993 to 2016. Materials and methods. A comparative analysis of the volume of treatment of patients with acute appendicitis, acute cholecystitis, acute pancreatitis, intestinal obstruction, perforated ulcer of the stomach and duodenum and strangulated hernia in surgical departments of Kuzbass from 1993 to 2016 to understand the changes occurring in abdominal surgery. Estimated in the comparative aspect for two decades (1993-2002 and 2007-2016 the average annual number of treated. The estimation of indicators in calculation on 100000 population is executed. The statistical processing was carried out using IBM SPSS Statistica computer version 24 and the nonparametric Mann-Whitney test. Result. Statistically significantly decreased the number of patients with acute appendicitis and perforated ulcers of the stomach and duodenum. The average annual hospitalization of patients with acute pancreatitis and strangulated abdominal hernias has significantly increased in the last decade. There are no significant differences in the increase in the total number of patients with acute cholecystitis and acute intestinal obstruction. Conclusions: 1. Over the past decade compared with 1993-2002, the incidence of acute appendicitis per 100000 thousand of the population decreased in the region by 39.9 %, the incidence of perforated gastric ulcer and duodenal ulcer by 30.2 %. 2. At this time, the number of people treated with 100000 people with acute pancreatitis increased by 94.7 %; with acute cholecystitis by 12.4 %; with an acute intestinal obstruction by 9.8 % and with a strangulated

Computed tomography (CT) exams were conducted to determine the distribution of abdominal fat identified based on the CT number measured in Hounsfield Units (HU) and to measure the volume of the abdominal visceral and subcutaneous fat in minipigs. The relationship between the CT-based fat volumes of several vertebral levels and the entire abdomen and anthropometric data including the sagittal abdominal diameter and waist circumference were evaluated. Moreover, the total fat volumes at the T11, T13, L3, and L5 levels were compared with the total fat volume of the entire abdomen to define the landmark of abdominal fat distribution. Using a single-detector CT, six 6-month-old male minipigs were scanned under general anesthesia. Three radiologists then assessed the HU value of visceral and subcutaneous abdominal fat by drawing the region of interest manually at the T11, T13, L1, L3, and L5 levels. The CT number and abdominal fat determined in this way by the three radiologists was found to be correlated (intra-class coefficient = 0.9). The overall HU ranges for the visceral and subcutaneous fat depots were -147.47 to -83.46 and -131.62 to -90.97, respectively. The total fat volume of the entire abdomen was highly correlated with the volume of abdominal fat at the T13 level (r = 0.97, p abdominal adipose tissue measured at the T13 level using CT is a strong and reliable predictor of total abdominal adipose volume.

Dynamic CT in the abdominal organ, 1

Fukuda, Kunihiko

1980-01-01

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

Durante los años 1970 el término empieza a extenderse en el discurso geográfico francés, aunque concebido muy a menudo en esa época como sinónimo de medio físico. Pero es partir de los años 1980 cuando el concepto de medio ambiente se convierte en un auténtico campo de estudios y de aplicaciones, relacionado a la vez con los diferentes aspectos del medio físico y las intervenciones humanas, estudiadas con un enfoque sistémico y dinámico. De esta forma, el enfoque geo-medioambiental no considera únicamente las interacciones entre el contexto natural y social, sino también los procesos de producción y de construcción que repiensan y renuevan a partir de ahora la relación naturaleza-cultura.

Contemporary imaging in abdominal emergencies

International Nuclear Information System (INIS)

Sivit, Carlos J.

2008-01-01

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

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

Abdominal radiography is frequently used in acute abdominal non-traumatic pain despite the availability of more advanced diagnostic modalities. This study evaluates the diagnostic accuracy of low-dose CT compared with abdominal radiography, at similar radiation dose levels. Fifty-eight patients were imaged with both methods and were reviewed independently by three radiologists. The reference standard was obtained from the diagnosis in medical records. Sensitivity and specificity were calculated. A systematic review was performed after a literature search, finding a total of six relevant studies including the present. Overall sensitivity with 95 % CI for CT was 75 % (66-83 %) and 46 % (37-56 %) for radiography. Specificity was 87 % (77-94 %) for both methods. In the systematic review the overall sensitivity for CT varied between 75 and 96 % with specificity from 83 to 95 % while the overall sensitivity for abdominal radiography varied between 30 and 77 % with specificity 75 to 88 %. Based on the current study and available evidence, low-dose CT has higher diagnostic accuracy than abdominal radiography and it should, where logistically possible, replace abdominal radiography in the workup of adult patients with acute non-traumatic abdominal pain.

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

Diagnosis of calcification on abdominal radiographs

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

To assess the outcomes of endovascular aortic aneurysm repair (EVAR) for the treatment of an abdominal aortic aneurysm in patients undergoing curative surgical treatment for concomitant abdominal malignancy. The study included 12 patients with abdominal neoplasia and an abdominal aortic aneurysm (AAA), which was treated by surgery and stent EVAR. The neoplasm consisted of the gastric, colorectal, pancreas, prostate, and gall bladder. The follow up period was 3-21 months (mean 11.8 months). All medical records and imaging analyses were reviewed by CTA and/or color Doppler US, retrospectively. Successful endoluminal repair was accomplished in all twelve patients. The mean interval time between EVAR and surgery was 58.6 days. Small amounts of type 2 endoleaks were detected in two patients (17%). One patient developed adult respiratory distress syndrome after Whipple's operation 20 days after surgery, which led to hopeless discharge. No procedure-related mortality, morbidity, or graft-related infection was noted. Exclusion of AAA in patients with accompanying malignancy show with a relatively low procedure morbidity and mortality. Hence, endoluminal AAA repair in patients with synchronous neoplasia may allow greater flexibility in the management of an offending malignancy

Purpose. To compare costs and reimbursements for three different treatments for uterine fibroids. Methods. Costs and reimbursements were collected and analyzed from the Thomas Jefferson University Hospital decision support database from 540 women who underwent abdominal hysterectomy (n 299), abdominal myomectomy (n = 105), or uterine fibroid embolization (UFE) (n = 136) for uterine fibroids during 2000-2002. We used the chi-square test and ANOVA, followed by Fisher's Least Significant Difference test, for statistical analysis. Results. The mean total hospital cost (US$) for UFE was $2,707, which was significantly less than for hysterectomy ($5,707) or myomectomy ($5,676) (p < 0.05). The mean hospital net income (hospital net reimbursement minus total hospital cost) for UFE was $57, which was significantly greater than for hysterectomy (-$572) or myomectomy (-$715) (p < 0.05). The mean professional (physician) reimbursements for UFE, hysterectomy, and myomectomy were $1,306, $979, and $1,078, respectively. Conclusion. UFE has lower hospital costs and greater hospital net income than abdominal hysterectomy or abdominal myomectomy for treating uterine fibroids. UFE may be more financially advantageous than hysterectomy or myomectomy for the insurer, hospital, and health care system. Costs and reimbursements may vary amongst different hospitals and regions

Review article: the functional abdominal pain syndrome.

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

The management of unexpected intra-abdominal malignancy, discovered at laparotomy for elective treatment of an abdominal aortic aneurysm (AAA), is controversial. It is still unclear whether both conditions should be treated simultaneously or a staged approach is to be preferred. To contribute in improving treatment guidelines, we retrospectively reviewed the records of patients undergoing laparotomy for elective AAA repair. From January 1994 to March 2003, 253 patients underwent elective, trans-peritoneal repair of an AAA. In four patients (1.6%), an associated, unexpected neoplasm was detected at abdominal exploration, consisting of one renal, one gastric, one ileal carcinoid, and one ascending colon tumor. All of them were treated at the same operation, after aortic repair and careful isolation of the prosthetic graft. The whole series' operative mortality was 3.6%. None of the patients simultaneously treated for AAA and tumor resection died in the postoperative period. No graft-related infections were observed. Simultaneous treatment of AAA and tumor did not prolong significantly the mean length of stay in the hospital, compared to standard treatment of AAA alone. Except for malignancies of organs requiring major surgical resections, simultaneous AAA repair and resection of an associated, unexpected abdominal neoplasm can be safely performed, in most of the patients, sparing the need for a second procedure. Endovascular grafting of the AAA can be a valuable tool in simplifying simultaneous treatment, or in staging the procedures with a very short delay.

Increases in abdominal fat have been reported with menopause, but the impact of menopause on abdominal fat distribution (visceral vs subcutaneous) is still unclear. The objective of the study was to determine if abdominal fat content (volume) or distribution is altered with menopause. Magnetic resonance imaging was used to quantify total abdominal, subcutaneous, and visceral fat in 8 healthy women, both in the premenopausal state and 8 years later in the postmenopausal state. Physical activity (PA) and blood lipids were also measured. Body weight and waist circumference did not change with menopause (pre- vs postmenopause: body weight, 63.2 +/- 3.1 vs 63.9 +/- 2.5 kg; waist circumference, 92.1 +/- 4.6 vs 93.4 +/- 3.7 cm); however, total abdominal fat, subcutaneous fat, and visceral fat all significantly (P fat distribution was not significantly different after menopause (pre- vs postmenopause: subcutaneous, 73% +/- 3% vs 71% +/- 3%; visceral, 26% +/- 3% vs 28% +/- 3%). Lean mass, fat mass, and PA, along with total cholesterol and triglyceride levels, did not change with menopause. High-density lipoprotein and low-density lipoprotein both increased (P abdominal fat content increased with menopause despite no change in PA, body weight, or waist circumference; however, menopause did not affect the relative abdominal fat distribution in these women.

Prophylactic antibiotics for penetrating abdominal trauma.

Penetrating abdominal trauma occurs when the peritoneal cavity is breached. Routine laparotomy for penetrating abdominal injuries began in the 1800s, with antibiotics first being used in World War II to combat septic complications associated with these injuries. This practice was marked with a reduction in sepsis-related mortality and morbidity. Whether prophylactic antibiotics are required in the prevention of infective complications following penetrating abdominal trauma is controversial, however, as no randomised placebo controlled trials have been published to date. There has also been debate about the timing of antibiotic prophylaxis. In 1972 Fullen noted a 7% to 11% post-surgical infection rate with pre-operative antibiotics, a 33% to 57% infection rate with intra-operative antibiotic administration and 30% to 70% infection rate with only post-operative antibiotic administration. Current guidelines state there is sufficient class I evidence to support the use of a single pre-operative broad spectrum antibiotic dose, with aerobic and anaerobic cover, and continuation (up to 24 hours) only in the event of a hollow viscus perforation found at exploratory laparotomy. To assess the benefits and harms of prophylactic antibiotics administered for penetrating abdominal injuries for the reduction of the incidence of septic complications, such as septicaemia, intra-abdominal abscesses and wound infections. Searches were not restricted by date, language or publication status. We searched the following electronic databases: the Cochrane Injuries Group Specialised Register, CENTRAL (The Cochrane Library 2013, issue 12 of 12), MEDLINE (OvidSP), Embase (OvidSP), ISI Web of Science: Science Citation Index Expanded (SCI-EXPANDED), ISI Web of Science: Conference Proceedings Citation Index- Science (CPCI-S) and PubMed.

Abdominal radiography is frequently used in acute abdominal non-traumatic pain despite the availability of more advanced diagnostic modalities. This study evaluates the diagnostic accuracy of low-dose CT compared with abdominal radiography, at similar radiation dose levels. Fifty-eight patients were imaged with both methods and were reviewed independently by three radiologists. The reference standard was obtained from the diagnosis in medical records. Sensitivity and specificity were calculated. A systematic review was performed after a literature search, finding a total of six relevant studies including the present. Overall sensitivity with 95 % CI for CT was 75 % (66-83 %) and 46 % (37-56 %) for radiography. Specificity was 87 % (77-94 %) for both methods. In the systematic review the overall sensitivity for CT varied between 75 and 96 % with specificity from 83 to 95 % while the overall sensitivity for abdominal radiography varied between 30 and 77 % with specificity 75 to 88 %. Based on the current study and available evidence, low-dose CT has higher diagnostic accuracy than abdominal radiography and it should, where logistically possible, replace abdominal radiography in the workup of adult patients with acute non-traumatic abdominal pain. • Low-dose CT has a higher diagnostic accuracy than radiography. • A systematic review shows that CT has better diagnostic accuracy than radiography. • Radiography has no place in the workup of acute non-traumatic abdominal pain.

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.

Full Text Available Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7% males and 20 (18.3% females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years. The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%, colon 48 (44%, and liver 41 (37.6%. Forty-four (40.4% patients had extra-abdominal injuries involving the chest in 17 (15.6%, musculoskeletal 12 (11%, and the head in 9 (8.3%. The most prevalent weapon injuries were gunshot 76 (69.7%, explosives 12 (11%, stab injuries 11 (10.1%, and blunt abdominal trauma 10 (9.2%. The injury severity score varied from 8 to 52 (mean: 20.8 with a fatality rate of 11 (10.1% and morbidity rate of 29 (26.6%. Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

Os animais de ambos os grupos ganharam peso, sem diferença estatistica. Na necrópsia retirava-se o segmento intestinal a partir do piloro até a valva ileocecal. Não houve diferença no comprimeto do intestino delgado em ambos os grupos. Porém, o intestino dos animais alimentados com NTP apresentaram diminuiçao significante de peso comparado com o grupo controle, independentemente da presença ou não de conteúdo. A resistência intestinal era menor no grupo NTP comparado ao controle, sendo mais significante no íleo. A altura dos vilos, a profundidade das criptas e a extensão da parede eram significantemente menores no íleo no grupo NTP comparado ao controle. Este achado foi observado também no jejuno, mas sem diferença significante. Conclui-se que nos ratos alimentados com NTP o intestino delgado perde massa e torna-se menos resistente, principalmente no íleo,apesar da manutenção do estado nutricional. A perda de massa aparece não apenas na mucosa mas em toda a parede intestinal.

Imaging the Abdominal Manifestations of Cystic Fibrosis

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

Full Text Available En la 4ª Conferencia Mundial sobre las Mujeres, celebrada en Pekín en septiembre de 1995, patrocinada por las Naciones Unidas, en el documento "Las mujeres y los medios de comunicación" ( se presentan varias reflexiones que inciden, por una parte, en incrementar la participación y el acceso de las mujeres a la expresión y a la toma de decisiones en y a través de los medios; y, por otra, en promover una imagen equilibrada y no estereotipada de ellas en los medios de comunicación. En este trabajo, partiendo de la constatación de la presencia de las mujeres en el cam po científico, reflexionamos sobre la necesidad de una Base de Datos de Mujeres Expertas como magnífica posibilidad para visibilizarlas en el discurso mediático.

Acumulación capitalista y nueva espacialidad en el Magdalena Medio

Full Text Available Este trabajo se propone identificar y presentar las tendencias del desarrollo capitalista en el Magdalena Medio colombiano desde el siglo XX, así como las relaciones con las dinámicas de acumulación nacional y global. Sostenemos que la producción social del espacio denominado Magdalena Medio ha seguido la ruta de procesos de acumulación por desposesión, ya sea en sus formas de vinculación a la lógica de producción capitalista o en las transformaciones de las formas de producción capitalistas allí donde ya existen; procesos que han estado atravesados por reconfiguraciones en las relaciones de poder de clase, del régimen político y de la dinámica del conflicto social y armado.

LOS DESASTRES NATURALES Y LOS MEDIOS EN COLOMBIA: ¿INFORMACIÓN PARA LA PREVENCIÓN?

Full Text Available En Colombia se ha estudiado poco la relación entre la sociedad y el tratamiento que hacen los medios de comunicación de los desastres naturales. Este es un objeto de estudio que le concierne el campo de investigación denominado comunicación de las ciencias. En este sentido, se necesitan enfoques transdiscplinarios que permitan entender las condiciones de producción de la información, la construcción mediática de los acontecimientos y las percepciones y apropiaciones por parte del público Algunos estudios han mostrado que hay una tendencia en los medios colombianos a detenerse en la descripción detallada de los acontecimientos, y poco en las explicaciones sobre sus causas y consecuencias, desde la perspectiva de los científicos y los expertos. Explicaciones que cuando aparecen son limitadas, o incluso se intercalan con las de carácter sobrenatural. Las aproximaciones sobre la recepción de la información son necesarias, de manera que no se entienda el tratamiento de este tipo de acontecimientos como simples manipulaciones por parte de los medios. Se ha mostrado cómo el público también elige, en la medida en que sus imaginarios son cercanos a los imaginarios “propuestos” por los medios, en relación con los desastres naturales. Pero, si bien son claras las responsabilidades de las autoridades y de la sociedad civil a este respecto, lo anterior no elude sino que invita a la discusión sobre las responsabilidades de los medios de comunicación colombianos en la prevención de los desastres naturales.

Adolescencia y deporte: ausencia de referentes femeninos en los medios para las adolescentes

Full Text Available La representación de las mujeres deportistas en los medios de comunicación españoles sigue siendo un campo de estudio poco analizado en comparación con el análisis de la presencia femenina en los medios desde una perspectiva generalista. El presente estudio tiene como objetivo reflexionar sobre su ausencia en el imaginario social, de manera que niñas y adolescentes carecen de modelos referentes a los cuales imitar. Si bien las investigaciones sobre la participación de la mujer en la información general sí tienen en cuenta las diferentes secciones o categorías informativas, son pocos los estudios propiamente dedicados a la imagen que se da en los medios de comunicación de las deportistas profesionales. En los pocos estudios existentes se confirma su infrarrepresentación y la apuesta, cada vez más frecuente, por las “invitadas” (mujeres objeto, sin más utilidad que la de acompañar al protagonista de la información: el deportista masculino, desabasteciendo a niños y jóvenes de modelos de referencia en los cuales fijarse.

Inventar o reflejar la realidad. Un dilema que compromete la credibilidad informativa de los medios de comunicación en Colombia

2002-01-01

Full Text Available En un contexto en el cual la tarea de informar que ejercen los medios masivos de comunicación se cuestiona constantemente, resulta imprescindible conocer la credibilidad que tienen las empresas informativas para los diversos actores de la sociedad colombiana. Es igualmente necesario, diferenciar la credibilidad y el consumo de medios y este último, a su vez, de la verdad o falsedad que conlleva la información. El artículo parte de una reciente encuesta del Observatorio de Medios de la Facultad de Comunicación Social y Periodismo de la Universidad de La Sabana, que revela las contradicciones que se pueden dar en la realidad colombiana, pues un medio que posee altos índices de consumo, muchas veces no genera la credibilidad esperada y, a su vez, medios de bajo consumo pueden estar dirigidos por periodistas de gran credibilidad. Todo indica que la opción de los medios para ser creíbles ante sus audiencias está en que puedan abrir espacios de participación ciudadana y permitir, de manera clara, la construcción de lo público y del sentir ciudadano.

Guzman-Stein, G.; Bonsack, M.; Liberty, J.; Delaney, J.P.

1989-01-01

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

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

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

Unusual causes of abdominal pain: sickle cell anemia.

Ahmed, Shahid; Shahid, Rabia K; Russo, Linda A

2005-04-01

Sickle cell disease is characterized by chronic hemolytic anemia and vaso-occlusive painful crises. The vascular occlusion in sickle cell disease is a complex process and accounts for the majority of the clinical manifestation of the disease. Abdominal pain is an important component of vaso-occlusive painful crises. It often represents a substantial diagnostic challenge in this population of patients. These episodes are often attributed to micro-vessel occlusion and infarcts of mesentery and abdominal viscera. Abdominal pain due to sickle cell vaso-occlusive crisis is often indistinguishable from an acute intra-abdominal disease process such as acute cholecystitis, acute pancreatitis, hepatic infarction, ischemic colitis and acute appendicitis. In the majority of cases, however, no specific cause is identified and spontaneous resolution occurs. This chapter will focus on etiologies, pathophysiology and management of abdominal pain in patients with sickle cell disease.

Computed tomography and nonoperative treatment for blunt abdominal trauma

1990-01-01

Studies were undertaken to determine if computed tomography (CT) could reliably assist physical examination in the initial assessment of blunt abdominal trauma, and also to examine how various abdominal injuries were managed with the guidance of CT. A total of 255 patients underwent emergency abdominal CT following blunt abdominal trauma over a period of seven years. One hundred and fifty two patients had abnormal CT scans, including 58 hepatic, 36 renal, 25 splenic and 9 pancreatic injuries as well as 67 patients with intra-abdominal hemorrhage and 21 patients with free abdominal air. A comparative study on the detection of pneumoperitoneum revealed CT to be far superior to plain radiography. One hundred and three patients had normal CT scans, all of whom were managed nonoperatively, except for three false-negative cases and two nontherapeutic cases. The patients with injury to the parenchymal organs were given nonoperative treatment if they had stable vital signs and no evidence of associated injuries demanding immediate surgery and the majority of these patients were managed well nonoperatively. CT was thus found to be a useful adjunct in the management of victims of blunt abdominal trauma, since in a rapid and noninvasive fashion, CT accurately defined the extent of parenchymal organ injury and also disclosed any other abdominal injuries.

To present our experience with abdominal tuberculosis in children and adolescents treated in our hospital from 2003 - 2014. It is a retrospective study. We have collected clinical records of inpatients overweight or obese and only 23.33% suffered of malnutrition. TB contact was present in 10 (33.33%). Positive tuberculin skin tests were seen in 10%. Extra-abdominal tuberculosis was found in 22 patients (63.32%). 12 cases had coexisting pulmonary tuberculosis and 4 cases had pleural effusion. 12 patients (40%) had tuberculous peritonitis; 12 patients (40%) had intestinal tuberculosis and peritoneal tuberculosis and 4 patients (13.33%) had intestinal tuberculosis. Bacteriological confirmation of tuberculosis was achieved in 10 cases (33.33%). Antituberculous therapy for 6 months was effective in 29 cases. One patient died who multifocal tuberculosis with HIV had associated. Abdominal tuberculosis is seen in 4.37% of children affected with tuberculosis, of which over 63% will have extra abdominal manifestations. Abdominal tuberculosis should be considered in patients with abdominal pain, fever, weight loss and abnormal chest radiography. Imaging can be useful for early diagnosis of abdominal tuberculosis.

From February 1986 to March 1988 113 abdominal US exams were performed in emergency situation to evaluate the accuracy of this methodology: 13 were blunt traumas, 18 post-operative complications. A real-time scanner with a linear probe of 5 MHz was employed. The results were confirmed by surgical and/or clinical and instrumental evaluation. In 81% of the examinations, ultrasonography allowed a diagnosis to be made. Gallbladder and biliary pathologies were the most common findings. The results (sensibility 96%, specificity 88%, accuracy 95%) confirm the affidability of ultrasonography in abdominal emergencies, as shown in literature

Full text: Heterotopic bone formation within the abdominal cavity is a rare complication of the posttraumatic abdominal surgery. There are only few cases reported in the medical literature and most of them involve the mesentery or the abdominal wall. A case of 49y-old men is presented who developed intraabdominal heterotopic ossifications as a consequence of numeral exploratory laparotomies performed after a blunt abdominal trauma. The condition was detected during the follow-up MDCT 11 months later. The case is of interest because of the rarity of the condition and the diffuse character of the calcifications in the abdominal structures, which could pose some differential diagnostic difficulties

Jejunal perforation caused by abdominal angiostrongyliasis Perfuração jejunal causada por angiostrongilíase abdominal

Full Text Available The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.Os autores descrevem caso de angiostrongilíase abdominal em doente adulto que se manifestou como abdômen agudo devido à perfuração de alça jejunal, evento raro, uma vez que esta afecção geralmente envolve o íleo terminal, apêndice, ceco ou cólon ascendente. A doença é causada pelo nematódeo Angiostrongylus costaricensis cujos hospedeiros definitivos são roedores silvestres e os hospedeiros intermediários são caracóis e caramujos.

Mattox, T Fleming; Stanford, Edward J; Varner, E

2004-01-01

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

Full Text Available Objectives - Arrowroot is an old-fashioned remedy for diarrhoea, but no clinical studies have been done to evaluate its effectiveness. The aim of this pilot study was to assess its efficacy as a treatment for diarrhoea in 11 patients, all of whom had irritable bowel syndrome with diarrhoea as a feature. Methods - The patients were interviewed and a questionnaire completed on entry into the trial. They then took 10 mL arrowroot powder three times a day for one month and discontinued the treatment for the subsequent month. Questionnaires were completed after one month on treatment and at the end of the trial after one month off treatment. Results - Arrowroot reduced diarrhoea and had a long-term effect on constipation. It also eased abdominal pain. Conclusion - Arrowroot is an effective treatment for diarrhoea. Its action could be explained by several theories which relate to an increase in faecal bulk and thus a more efficient bowel action. The number of patients was small, and further studies are needed to substantiate preliminary results.Objetivos - Araruta é um antigo (absoleto remédio usado para a diarréia, porém estudos clínicos não têm sido realizados para avaliar sua efetividade.

Recurrent abdominal pain (RAP) is a common complaint in children. Significant portion of them are of functional origin. This study aimed to assess the prevalence of abdominal pain-predominant functional gastrointestinal disorder (FGID) and its types in Jordanian school children. This is a school-based survey at south Jordan. Information using the self-reporting form of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-RIII) - the official Arabic translation - was collected. Classes from academic years (grades) 6 - 8 were selected. SPSS Statistical Package Version 17 (IBM, Armonk, NY, USA) was used. Categorical data were analyzed using Fisher's exact test, and continuous data were analyzed using t -test. P abdominal pain-predominant FGID. Seventy-nine (68%) of them were females. Forty-seven (10.6%) had irritable bowel syndrome (IBS). Thirty-six (8%), 17 (3.8%), 11 (2.4%) and five (1.1%) had abdominal migraine, functional abdominal pain, functional abdominal pain syndrome and functional dyspepsia, respectively. Abdominal pain-predominant FGID has become a major health issue in Jordanian children. One of four children between the ages of 11 and 15 years exhibits at least one abdominal pain-predominant FGID. The most common form of abdominal pain-predominant FGID in our children was IBS. Females are affected more often than males. Intestinal and extra-intestinal symptoms are seen regularly with abdominal pain-predominant FGIDs.

Abdominal wall Actinomycosis is a rare disease associated with the use of intrauterine device and as a complication of abdominal surgery. Diagnosis is difficult because it is unusual and behaves like a malignant neoplasm. A case report is presented of a patient who had used an intrauterine device for four years and developed a stony tumour in the abdominal wall associated with a set of symptoms that, clinically and radiologically, was simulating a peritoneal carcinomatosis associated with paraneoplastic syndrome, even in the course of an exploratory laparotomy. The patient attended our hospital with a two-month history of abdominal pain and symptoms that mimic a paraneoplastic syndrome. The diagnosis of abdominal actinomycosis was suspected by the finding of the microorganism in cervical cytology together with other cultures and Actinomyces negative in pathological studies, confirming the suspicion of a complete cure with empirical treatment with penicillin. Actinomycosis should be considered in patients with pelvic mass or abdominal wall mass that mimics a malignancy. Antibiotic therapy is the first treatment choice and makes a more invasive surgical management unnecessary. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A.

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

Science.gov (United States)

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.

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

The surgical site infection (SSI) is a common complication of abdominal operation. It relates to increased hospital stay, increased healthcare cost, and decreased patient's quality of life. Obesity, usually defined by BMI, is known as one of the risks of SSI. However, the thickness of subcutaneous layers of abdominal wall might be an important local factor affecting the rate of SSI after the abdominal operations. The objective of this study is to assess the importance of the abdominal wall thickness on incisional SSI rate. The subjects of the present study were patients who had undergone major abdominal operations at Thammasat University Hospital between June 2013 and May 2014, and had been investigated with CT scans before their operations. The demographic data and clinical information of these patients were recorded. The thickness ofsubcutaneous fatty tissue from skin down to the most superficial layer of abdominal wall muscle at the surgical site was measured on CT images. The wound infectious complication was reviewed and categorized as superficial and deep incisional SSIfollowing the definition from Centersfor Disease Control and Prevention (CDC) guidelines. The significance ofeach potentialfactors on SSI rates was determined separately with student t-test for quantitative data and χ2-test for categorical data. Then all factors, which had p operative CTscans. Post-operative SSI was 25.2% (35/139), superficial and deep types in 27 and 8 patients, respectively. The comparison of abdominal wall thickness between patients with and without infection was significantly different (20.0 ± 8.4 mm and 16.0 ± 7.2 mm, respectively). When the thickness at 20 mm was used as the cut-off value, 43 of 139 patients had abdominal wall thickness ≥ 20 mm. The incidence of SSI of the thickness ±20 mm group was 37.2% (16/43) and of the less thickness group was 19.8% (19/96), with p operation. However, only abdominal wall thickness and wound classification were still significant

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

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

Full Text Available Excessive abdominal fat contributes to the development of chronic nontransmissible diseases. Dual emission X Ray absorptiometry (DXA is a simple to administer technique that allows abdominal fat percentage (%abdominalFDXA to be determined. Anthropometric measurements, which have been validated and are of low cost, such as the abdominal circumferences 2.5cm above the umbilical scar (ABC2,5 and level with the umbilical scar (ABCum, are used as indicators of abdominal fat. Skin folds (SF are little used for this purpose. The objective of this study was to verify which of these anthropometric indicators best correlates with and best explains abdominalFDXA. The sample was made up of 22 women (43.9±11.6 years; 34.7±8.3 %G totalDXA and 18 men (31.9±11.6 years; 19.0±8.0 %G totalDXA who were measured for ABC2.5, ABCum, suprailiac SF (SI, midaxillary SF (AM and abdominal SF (AB, while abdominalF (L1-L4 was measured by DXA.

Full Text Available Background: Waist circumference perimeter, as an indirect indicator of abdominal obesity, is commonly presented as an essential element in the clinical assessment of obesity. The link between abdominal obesity and insulin resistance is proposed as the core of metabolic syndrome’s pathophysiology and complications. Objective: To determine whether individuals with abdominal obesity present characteristics related to metabolic syndrome’s factors that differ from those observed in individuals with no abdominal obesity. Methods: A comparative analytical study was performed including cases control and design in two different groups. The sample was composed of 98 individuals of both sexes randomly selected out of a universe of 510 workers population at the Medical University of Cienfuegos from September to December 2005. They were all tested as to blood pressure, cholesterol, HDL cholesterol, fasting glucose and triglycerides. Results: Abdominal obesity was found in 30.6% of individuals. It was predominant in females (83.3% older than 40 years. The number of cases of obesity linked to hypertension was similar to the number of cases with low HDL cholesterol (53.3%. Impaired glucose was found in 16.7% of cases. Conclusions: Abdominal obesity is a health problem in the population included in this study and it increases as age does. Individuals with abdominal obesity are exposed to a higher risk of metabolic disorders, such as low levels of HDL cholesterol, high levels of triglycerides and total cholesterol, glucose alterations and hypertension.

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

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

Full Text Available Penetrating abdominal trauma has been traditionally treated by exploratory laparotomy. Nowadays laparoscopy has become an accepted practice in hemodynamically stable patient without signs of peritonitis. We report a case of a lower anterior abdominal gunshot patient treated laparoscopically. A 32-year-old male presented to the Emergency Department with complaint of gunshot penetrating injury at left lower anterior abdominal wall. The patient had no symptoms or obvious bleeding and was vitally stable. On examination we identified 1 cm diameter entry wound at the left lower abdominal wall. The imaging studies showed the bullet in the peritoneal cavity but no injured intraperitoneal and retroperitoneal viscera. We decided to remove the bullet laparoscopically. Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically.

Full Text Available Abdominal pocketing is one of the most useful methods in salvation of compromised replanted fingertips. Abdominal pocketing has generally been performed in the ipsilateral lower abdominal quadrant, but we have also performed contralateral pocketing at our institute. To determine which approach is more beneficial, a total of 40 patients underwent an abdominal pocketing procedure in either the ipsilateral or contralateral lower abdominal quadrant after fingertip replantation. Dates of abdominal pocketing after initial replantation, detachment after abdominal pocketing, range of motion (ROM before abdominal pocketing, and sequential ROM after the detachment operation and date of full ROM recovery and Disabilities of Arm, Shoulder, and Hand questionnaire (DASH score were recorded through medical chart review. Mean detachment date, mean abduction of shoulder after the detachment operation, and mean days to return to full ROM were not significantly different between the ipsilateral and contralateral pocketing groups. However, the mean DASH score was significantly lower in the contralateral group than the ipsilateral group. There were also fewer postoperative wound complications in the contralateral group than in the ipsilateral group. We, therefore, recommend contralateral abdominal pocketing rather than ipsilateral abdominal pocketing to increase patient comfort and reduce pain and complications.

Temporary abdominal closure with zipper-mesh device for management of intra-abdominal sepsis

Directory of Open Access Journals (Sweden)

Edivaldo Massazo Utiyama

Full Text Available OBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years; 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

Hernia Following Blunt Abdominal Trauma

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

to assess predictors of intra-abdominal injuries in blunt trauma patients admitted without abdominal pain or abnormalities on the abdomen physical examination. We conducted a retrospective analysis of trauma registry data, including adult blunt trauma patients admitted from 2008 to 2010 who sustained no abdominal pain or abnormalities on physical examination of the abdomen at admission and were submitted to computed tomography of the abdomen and/or exploratory laparotomy. Patients were assigned into: Group 1 (with intra-abdominal injuries) or Group 2 (without intra-abdominal injuries). Variables were compared between groups to identify those significantly associated with the presence of intra-abdominal injuries, adopting ptrauma mechanism (ptrauma mechanism (p=0.008 - OR 2.85; 95%CI 1.13-6.22) and abnormal neurological physical exam at admission (p=0.015 - OR 0.44; 95%CI 0.22-0.85). Intra-abdominal injuries were predominantly associated with trauma mechanism and presence of chest injuries.

Abdominal aortic aneurysm (AAA) is most commonly defined as a maximal diameter of the abdominal aorta in excess of 3 cm in either anterior-posterior or transverse planes or, alternatively, as a focal dilation ≥ 1.5 times the diameter of the normal adjacent arterial segment. Risk factors for the development of AAA include age > 60, tobacco use, male gender, Caucasian race, and family history of AAA. Aneurysm growth and rupture risk appear to be associated with persistent tobacco use, female gender, and chronic pulmonary disease. The majority of AAAs are asymptomatic and detected incidentally on various imaging studies, including abdominal ultrasound, and computed tomographic angiography. Symptoms associated with AAA may include abdominal or back pain, thromboembolization, atheroembolization, aortic rupture, or development of an arteriovenous or aortoenteric fistula. The Screening Abdominal Aortic Aneurysms Efficiently (SAAAVE) Act provides coverage for a one-time screening abdominal ultrasound at age 65 for men who have smoked at least 100 cigarettes and women who have family history of AAA disease. Medical management is recommended for asymptomatic patients with AAAs  5 mm/6 months), or presence of a fusiform aneurysm with maximum diameter of 5.5 cm or greater. Intervention for AAA includes conventional open surgical repair and endovascular aortic stent graft repair.

Abdominal obesity is a better marker of adverse metabolic profile than generalized obesity in hypertensive subjects. Further, gender has effect on adiposity and its distribution. Effect of gender on obesity and the distribution of fat in different sub-compartments of abdomen among Indian hypertensive subjects. This observational study included 278 adult subjects (Males-149 & Females-129) with essential hypertension from a tertiary care centre in north India over one year. A detailed history taking and physical examination including anthropometry were performed in all patients. Total Abdominal Fat (TAF) and abdominal adipose tissue sub-compartments like Intra-Abdominal Adipose Tissue (IAAT) and Sub-Cutaneous Adipose Tissue (SCAT) were measured using the predictive equations developed for Asian Indians. Female hypertensive subjects had higher Body Mass Index (BMI) with more overweight (BMI ≥ 23kg/m(2)), and obesity (BMI≥ 25 kg/m(2)). Additionally, they had higher prevalence of central obesity based on both Waist Circumference (WC) criteria (WC≥ 90 cm in males and WC≥ 80 cm in females) and TAF criteria {≥245.6 cm(2) (males) and ≥203.46 cm(2) (females)} than male patients. But there was no difference in the prevalence of central obesity based on Waist Hip Ratio (WHR) criteria (WHR ≥0.90 in males and WHR ≥ 0.85 in females) between two genders. High TAF & IAAT were present in more females although there was no difference in the distribution of high SCAT between two genders. Female hypertensive subjects were more obese with higher abnormal TAF & IAAT compared to male patients. However, there was no difference in the distribution of high SCAT among them.

To test the accuracy and reproducibility of ultrasound and computed tomography (CT) for the quantification of abdominal fat in correlation with the anthropometric, clinical, and biochemical assessments. Using ultrasound and CT, we determined the thickness of subcutaneous and intra-abdominal fat in 101 subjects-of whom 39 (38.6%) were men and 62 (61.4%) were women-with a mean age of 66.3 years (60-80 years). The ultrasound data were correlated with the anthropometric, clinical, and biochemical parameters, as well as with the areas measured by abdominal CT. Intra-abdominal thickness was the variable for which the correlation with the areas of abdominal fat was strongest (i.e., the correlation coefficient was highest). We also tested the reproducibility of ultrasound and CT for the assessment of abdominal fat and found that CT measurements of abdominal fat showed greater reproducibility, having higher intraobserver and interobserver reliability than had the ultrasound measurements. There was a significant correlation between ultrasound and CT, with a correlation coefficient of 0.71. In the assessment of abdominal fat, the intraobserver and interobserver reliability were greater for CT than for ultrasound, although both methods showed high accuracy and good reproducibility.

Empirically, equine distal limb lameness is often linked to hoof imbalance. To objectively quantify dynamic toe-heel and medio-lateral hoof balance of the vertical ground reaction force in sound sport horses, seven Royal Dutch Sport Horses were led at the walk and trot over a dynamically calibrated pressure plate. Forelimb hoof prints were divided into a toe and heel region and a medial and lateral zone. Toe-heel and medio-lateral hoof balance of the vertical ground reaction force were calculated throughout the stance. Toe-heel balance was highly symmetrical between contralateral limbs at both gaits. At the walk, medio-lateral balance of both forelimbs presented higher loading in the lateral part of the hoof throughout the stance. However, at the trot, left medio-lateral balance presented higher loading of the medial part of the hoof at impact, whereas the right limb showed higher loading of the lateral part of the hoof in all horses, and both limbs presented increased lateral loading at the end of the stance. This study provides objective data for toe-heel and medio-lateral hoof balance in sound sport horses. Copyright © 2013 Elsevier Ltd. All rights reserved.

Intra-abdominal fat obesity, which is linked with the metabolic syndrome, is usually characterized by measuring intra-abdominal fat area at the umbilical level of abdominal CT scan. In recent year, the chances of chest CT scanning are increased, as lung cancer screening survey or individual medical examination. Thus, we presented a method of measuring the areas of intra-abdominal fat and subcutaneous fat at the lower slice of chest CT scan. Fat areas found with this method were significantly correlated with those obtained at the umbilical level. (author)

Invasive meningococcal disease (IMD) is recognized as septicemia and/or meningitis. However, early symptoms may vary and are frequently nonspecific. Early abdominal presentations have been increasingly described. We aimed to explore a large cohort of patients with initial abdominal presentations for association with particular meningococcal strains. Confirmed IMD cases in France between 1991-2016 were screened for the presence within the 24 hours before diagnosis of at least one of the following criteria (1) abdominal pain, (2) gastro-enteritis with diarrhea and vomiting, (3) diarrhea only. Whole genome sequencing was performed on all cultured isolates. We identified 105 cases (median age 19 years) of early abdominal presentations with a sharp increase since 2014. Early abdominal pain alone was the most frequent symptom (n=67, 64%), followed by gastro-enteritis (n=26, 25%) and diarrhea alone (n=12, 11%). Twenty patients (20%) had abdominal surgery. A higher case fatality rate (24%) was observed in these cases compared to 10.4% in all IMD in France (p=0.007) with high levels of inflammation markers in the blood. Isolates of group W were significantly more predominant in these cases compared to all IMD. Most of these isolates belonged to clonal complex ST-11 (cc11) of the sublineages of the South American-UK strain. Abdominal presentations are frequently provoked by hyperinvasive isolates of meningococci. Delay in the management of these cases and the virulence of the isolates may explain the high fatality rate. Rapid recognition is a key element to improve their management.

Unexplained abdominal pain is a common but difficult presenting feature faced by the clinicians. Such patients can undergo a number of investigations with failure to reach any diagnosis. The objective of this study was to evaluate the use of laparoscopy in the diagnosis and management of patients with unexplained abdominal pain. Methods: This cross-sectional study was conducted at Pakistan Institute of Medical Sciences Islamabad from January 2009 to December 2013. This study included 91 patients of unexplained abdominal pain not diagnosed by routine clinical examination and investigations. These patients were subjected to diagnostic laparoscopy for evaluation of their conditions and to confirm the diagnosis. These patients presented 43% of patients undergoing investigations for abdominal pain. Patients diagnosed with gynaecological problems were excluded to see surgeon's perspective. The findings and the outcomes of the laparoscopy were recorded and data was analyzed. Results: Unexplained abdominal pain is common in females than in males. The most common laparoscopic findings were abdominal tuberculosis followed by appendicitis. Ninety percent patients achieved pain relief after laparoscopic intervention. Conclusion: Laparoscopy is both beneficial and safe in majority of patients with unexplained abdominal pain. General surgeons should acquire training and experience in laparoscopic surgery to provide maximum benefit to these difficult patients. (author)

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

Aim: To compare the effect of an initial early computed tomography (CT) examination versus standard practice (SP) on the length of hospital stay, diagnostic accuracy, and mortality of adults presenting with acute abdominal pain. Materials and methods: Two hundred and five adults presenting with acute abdominal pain were randomized to undergo an early CT examination or current SP, which comprised supine abdominal and erect chest radiography. One hundred and ninety-eight patients (99 in each arm) were included in the analysis. The primary endpoint was the duration of inpatient stay; secondary endpoints were diagnostic certainty and mortality. Results: There was no significant difference in the length of hospital stay between the two arms (p = 0.20). At randomization 36% (35 of 96) of CT patients and 49% (48 of 98) of SP patients were correctly diagnosed; 24 h after randomization the correct diagnosis had been established in 84% of CT patients and 73% of SP patients. This refinement in diagnostic certainty was significantly better in the CT group (p < 0.001). There was no difference in mortality between the two trial arms (p = 0.31). Conclusion: Early abdominal CT in patients with acute abdominal pain improves diagnostic certainty, but does not reduce the length of hospital stay and 6 month mortality

1999-08-01

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

The nutrient loads of the reservoirs Mulargia and Medio Flumendosa (Centre-South Sardinia) were studied in the framework of an interdisciplinary study on the causes of phytoplankton blooms (in particular of Cyanophyta Oscillatoria rubescens D. C.). The sources considered were the tributaries and atmospheric deposition on the lake surface. The study period (July 1991-June 1992) was characterized by amounts of precipitation and discharge lower than the pluriannual means. The atmospheric load resulted significant for N but negligible for P. The P load from the watershed was 10.6 and 10.8 t a -1 for lakes Medio Flumendosa and Mulargia, respectively; the values for N were 51.8 and 108 t a -1 . Nutrient loads are discussed both in relation to population and economic activity in the watersheds and as regards their effects on the lake trophic level

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

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.

Out of 75 patients who were admitted to our hospital because of abdominal trauma and were undergone the procedures such as ultrasonography and/or CT scan within 24 hours of abdominal trauma due to suspected abdominal organ injury. We analyzed the results of 38 patients who were confirmed of diagnosis by operation, follow-up CT scan or ultrasonography. We analyzed the results of 38 patients who were confirmed of diagnosis by operation, follow-up CT scan or ultrasonography. 1. In the abdominal organ injury, solid organ injury consists of 8 cases of spleen laceration, 1 of splenic subcapsular hematoma, 7 of hepatic laceration, 7 of pancreas laceration, 3 of renal laceration, and 3 of subcapsular hematoma of kidney. 2. In addition, there were 7 bowel and/or mesenteric laceration, 2 diaphragmatic hernia, and 1 urethral rupture. 3. 2 cases of retroperitoneal hematoma and 1 case in which hemo peritoneum occurred without abdominal organ injury were confirmed by follow-up CT or ultrasonography. 4. In all of the 4 patients with multiple organ injury, pancreatic laceration was associated. 5. In abdominal trauma patients, ultrasonography or CT can be used to survey rapidly the entire abdomen for possible associated injury, and be of great help to clinicians in identifying the patients who need immediate surgery or in minimizing the incidence of unnecessary emergency abdominal exploration.

A significant proportion of children with functional abdominal pain develop chronic pain. Identifying clinical characteristics predicting pain persistence is important in targeting interventions. We examined whether child anxiety and/or pain-stooling relations were related to maintenance of abdominal pain frequency and compared the predictive value of 3 methods for assessing pain-stooling relations (ie, diary, parent report, child report). Seventy-six children (7-10 years old at baseline) who presented for medical treatment of functional abdominal pain were followed up 18 to 24 months later. Baseline anxiety and abdominal pain-stooling relations based on pain and stooling diaries and child- and parent questionnaires were examined in relationship to the persistence of abdominal pain frequency. Children's baseline anxiety was not related to persistence of pain frequency. Children who, however, displayed irritable bowel syndrome (IBS) symptoms at baseline maintained pain frequency at follow-up, whereas in children in whom there was no relationship between pain and stooling, pain frequency decreased. Pain and stool diaries and parent report of pain-stooling relations were predictive of pain persistence but child-report questionnaires were not. The presence of IBS symptoms in school-age children with functional abdominal pain appears to predict persistence of abdominal pain over time, whereas anxiety does not. Prospective pain and stooling diaries and parent report of IBS symptoms were predictors of pain maintenance, but child report of symptoms was not.

Li Shao

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

Diagnosis of abdominal abscesses with 67gallium

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

Limited valid data are available regarding the association of fructose-induced symptoms, fructose malabsorption, and clinical symptoms. To develop a questionnaire for valid symptom assessment before and during a carbohydrate breath test and to correlate symptoms with fructose breath test results in children/adolescents with functional abdominal pain. A Likert-type questionnaire assessing symptoms considered relevant for hydrogen breath test in children was developed and underwent initial validation. Fructose malabsorption was determined by increased breath hydrogen in 82 pediatric patients with functional abdominal pain disorders; fructose-induced symptoms were quantified by symptom score ≥2 and relevant symptom increase over baseline. The results were correlated with clinical symptoms. The time course of symptoms during the breath test was assessed. The questionnaire exhibited good psychometric properties in a standardized assessment of the severity of carbohydrate-related symptoms. A total of 40 % (n = 33) had malabsorption; symptoms were induced in 38 % (n = 31), but only 46 % (n = 15) with malabsorption were symptomatic.

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

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

Full Text Available Com o objetivo de estudar a morfologia e determinar a localização da enzima fosfatase ácida na região distal do intestino delgado de bezerros, do nascimento ao fechamento intestinal, foram coletadas amostras de 15 animais machos em três idades: ao nascer sem que houvesse a ingestão de colostro; três horas após a ingestão da primeira refeição de colostro e aos três dias de idade. Observou-se, ao nascimento, a presença de um grande vacúolo, que dominava todo o citoplasma das células epiteliais do jejuno distal e íleo. Após a ingestão de colostro, verificou-se o acúmulo de material absorvido nesses vacúolos. Foi detectada a reação de fosfatase ácida nas células absortivas de bezerros recém-nascidos, antes e após a ingestão de colostro. Aos três dias de idade, uma nova população de células geralmente não vacuoladas, com sistema endocítico apical reduzido, foi observada recobrindo as vilosidades intestinais. Portanto, em bezerros a maturação do epitélio absortivo do intestino delgado distal pode iniciar-se com o aumento da atividade enzimática nos vacúolos absortivos, culminando com a rápida substituição das células fetais por células diferenciadas não pinocíticas, o que determinaria o término da transferência de anticorpos maternos.The localization of acid phosphatase at distal small intestine and its morphology were studied f0rom birth to intestinal closure from fifteen male dairy calves aged: unsuckled neonatal, three hours after colostrum ingestion and three days old. At birth, the presence of a large vacuole was found and it expanded all over the epithelial cells cytoplasm at distal jejunum and ileum. For colostrum fed calves, ingested material could be observed in the vacuole. The phosphatase acid reaction was detected in the absorptive cells of suckled and unsuckled newborn calves. Calves aged three days old, a new population of non-vacuolated cells and reduced apical endocytic system were found

Effects of abdominal pressure on venous return: abdominal vascular zone conditions.

Science.gov (United States)

Takata, M; Wise, R A; Robotham, J L

1990-12-01

The effects of changes in abdominal pressure (Pab) on inferior vena cava (IVC) venous return were analyzed using a model of the IVC circulation based on a concept of abdominal vascular zone conditions analogous to pulmonary vascular zone conditions. We hypothesized that an increase in Pab would increase IVC venous return when the IVC pressure at the level of the diaphragm (Pivc) exceeds the sum of Pab and the critical closing transmural pressure (Pc), i.e., zone 3 conditions, but reduce IVC venous return when Pivc is below the sum of Pab and Pc, i.e., zone 2 conditions. The validity of the model was tested in 12 canine experiments with an open-chest IVC bypass. An increase in Pab produced by phrenic stimulation increased the IVC venous return when Pivc-Pab was positive but decreased the IVC venous return when Pivc - Pab was negative. The value of Pivc - Pab that separated net increases from decreases in venous return was 1.00 +/- 0.72 (SE) mmHg (n = 6). An increase in Pivc did not influence the femoral venous pressure when Pivc was lower than the sum of Pab and a constant, 0.96 +/- 0.70 mmHg (n = 6), consistent with presence of a waterfall. These results agreed closely with the predictions of the model and its computer simulation. The abdominal venous compartment appears to function with changes in Pab either as a capacitor in zone 3 conditions or as a collapsible Starling resistor with little wall tone in zone 2 conditions.

Objectives To monitor the early effect of a national population screening programme for abdominal aortic aneurysm in 65-year-old men. Setting The study used national statistics for death rates from abdominal aortic aneurysm (Office of National Statistics) and hospital admission data in England (Hospital Episode Statistics). Methods Information concerning deaths from abdominal aortic aneurysm (ruptured and non-ruptured) (1999-2014) and hospital admissions for ruptured abdominal aortic aneurysm (2000-2015) was examined. Results The absolute number of deaths from abdominal aortic aneurysm in men and women aged 65 and over has decreased by around 30% from 2001 to 2014, but as the population has increased, the relative reduction was 45.6% and 40.0%, respectively. Some 65% of all abdominal aortic aneurysm deaths are in men aged over 65; women aged 65 and over account for around 31%. Deaths from ruptured abdominal aortic aneurysm in men aged 60-74 (the screened group) appear to be declining at the same rate as in men aged 75 and over. The relative decline in admissions to hospital with ruptured abdominal aortic aneurysm may be greater in men and women aged 60-74 (which contains the screened group of men), than those older, giving the first possible evidence that abdominal aortic aneurysm screening is having an effect. Conclusion The death rate from abdominal aortic aneurysm is declining rapidly in England. There is the first evidence that screening may be contributing to this reduction.

Previous abdominal wall surgery is viewed as a contraindication to abdominal free tissue transfer. We present two patients who underwent multiple abdominal liposuction procedures, followed by successful free deep inferior epigastric artery perforator flap. We review the literature pertaining to reliability of abdominal free flaps in those with previous abdominal surgery. Review of case notes and radiological investigations of two patients, and a PubMed search using the terms "DIEP", "deep inferior epigastric", "TRAM", "transverse rectus abdominis", "perforator" and "laparotomy", "abdominal wall", "liposuction", "liposculpture", "fat graft", "pfannenstiel", with subsequent appraisal of relevant papers by the first and second authors. Patient 1 had 3 episodes of liposuction from the abdomen for fat grafting to a reconstructed breast. Subsequent revision reconstruction of the same breast with DIEP flap was preceded by CT angiography, which demonstrated normal perforator anatomy. The reconstruction healed well with no ischaemic complications. Patient 2 had 5 liposuction procedures from the abdomen to graft fat to a wide local excision defect. Recurrence of cancer led to mastectomy and immediate reconstruction with free DIEP flap. Preoperative MR angiography demonstrated a large perforator right of the umbilicus, with which the intraoperative findings were consistent. The patient had an uneventful recovery and good healing with no fat necrosis or wound dehiscence. We demonstrate that DIEP flaps can safely be raised without perfusion-related complications following multiple liposuction procedures to the abdomen. The safe interval between procedures is difficult to quantify, but we demonstrate successful free flap after 16 months.

To evaluate the imaging findings of abdominal extraosseous plasma cell neoplasm. From April 2000 to January 2005, eight patients (four men, four women; mean age, 50.6 years) with pathologically proved, extraosseous plasma cell neoplasm involving the abdominal organs were included in this study. The diagnoses were based on consensus agreement between two radiologists who retrospectively reviewed CT, ultrasonography, and enteroclysis findings. We evaluated the findings by focusing on the location, size, margin, and enhancement pattern of the lesion, and lymphadenopathy on each image. There were multiple myeloma in four patients and extramedullary plasmacytoma in the remaining four. Involved abdominal organs were the liver (n = 4), spleen (n 4), lymph node (n = 3), stomach (n = 1), small bowel (n = 1), and colon (n 1). The hepatic involvement of plasma cell neoplasm presented as a homogeneous, well-defined, solitary mass (n = 1), multiple nodules (n = 1), and hepatomegaly (n = 2). Its involvement of the spleen and lymph node appeared as splenomegaly and lymphadenopathy, respectively. Its involvement of the gastrointestinal tract including the stomach, small bowel, and colon, presented as a homogeneous, diffuse wall thickening or mass in the gastrointestinal tract. Abdominal extraosseous plasma cell neoplasm involves occasionally the liver, spleen, and lymph node, and rarely the gastrointestinal tract. When we encounter a well-defined, homogeneous lesion of the abdominal organs in patients diagnosed or suspected as having plasma cell neoplasm, we should consider its involvement of the abdominal organs

Although abdominal pain is a symptom of several structural gastrointestinal disorders (eg, peptic ulcer disease), this comprehensive review will focus on the 4 most common nonstructural, or functional, disorders associated with abdominal pain: functional dyspepsia, constipation-predominant and diarrhea-predominant irritable bowel syndrome, and functional abdominal pain syndrome. Together, these conditions affect approximately 1 in 4 people in the United States. They are associated with comorbid conditions (eg, fibromyalgia, depression), impaired quality of life, and increased health care utilization. Symptoms are explained by disordered gastrointestinal motility and sensation, which are implicated in a variety of peripheral (eg, postinfectious inflammation, luminal irritants) and/or central (eg, stress and anxiety) factors. These disorders are defined and can generally be diagnosed by symptoms alone. Often prompted by alarm features, selected testing is useful to exclude structural disease. Identifying the specific diagnosis (eg, differentiating between functional abdominal pain and irritable bowel syndrome) and establishing an effective patient-physician relationship are the cornerstones of therapy. Many patients with mild symptoms can be effectively managed with limited tests, sensible dietary modifications, and over-the-counter medications tailored to symptoms. If these measures are not sufficient, pharmacotherapy should be considered for bowel symptoms (constipation or diarrhea) and/or abdominal pain; opioids should not be used. Behavioral and psychological approaches (eg, cognitive behavioral therapy) can be very helpful, particularly in patients with chronic abdominal pain who require a multidisciplinary pain management program without opioids.

Estos cistacantos se inocularon en ratas, ratones, hamsters y un cachorro de perro, que resultaron todos infectados. Los parásitos se localizaron principalmente en la cavidad abdominal y/o adheridos a la mucosa del intestino delgado y grueso. El hombre puede infectarse con estos parásitos al ingerir E. analoga infectados.

Clinical application of PET in abdominal cancers

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

To investigate the prevalence of lactose and fructose intolerance in children with chronic abdominal pain. Hydrogen breath tests were done to detect lactose and fructose malabsorption in 86 children with chronic abdominal pain (44 irritable bowel syndrome, 24 functional abdominal pain and 17 functional abdominal pain syndrome as per Rome III criteria) presenting to a Pediatric Gastroentreology department. 14 (16.3%) of patients were diagnosed with lactose intolerance and 11 (12.8%) with fructose intolerance. Lactose and fructose intolerance in children can lead to chronic abdominal pain and symptoms improve with dietary modifications.

Full Text Available El presente ensayo revisa la relación que han mantenido las universidades con los medios de comunicación, como recursos tecnológicos útiles para ejercer sus funciones sustantivas; delínea la coyuntura histórica que vive el mundo, y explica el papel que los medios han cumplido en este proceso de transformación de los paradigmas culturales que habían guiado las prácticas académicas en Occidente. Aclara la forma en cómo las universidades están siendo obligadas a cambiar para ajustarse a las nuevas condiciones y presiones de su entorno; y finalmente, propone que el sentido del cambio debe darse a través del fortalecimiento de los programas de extensión universitaria, particularmente los de educación continua, a distancia y de difusión cultural.

Diagnostic ultrasonography in cattle with abdominal fat necrosis.

Tharwat, Mohamed; Buczinski, Sébastien

2012-01-01

This study describes the ultrasonographic findings in 14 cows with abdominal fat necrosis. Ultrasonography of the abdomen revealed the presence of heterogeneous hyperechoic masses and hyperechoic omentum with localized masses floating in a hypoechoic peritoneal fluid. A hyperechogenic rim was imaged around both kidneys. The intestines were coated with hyperechoic capsules and the intestinal lumens were constricted. Ultrasonographic examination of the pancreatic parenchyma showed an overall increased echogenicity which was homogenously distributed in 3 cases. A diagnosis of abdominal fat necrosis was made with ultrasound-guided biopsy of the echogenic masses, and thereafter at postmortem examination. Results from this study demonstrate the efficacy of ultrasonography as an imaging modality for antemortem diagnosis of abdominal lipomatosis in cattle. To the authors' knowledge, this study is the first that illustrates ultrasonographic findings in cattle affected with abdominal lipomatosis.

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

Penetrating abdominal injuries: management controversies

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