    Full Text Available OBJETIVO: Comparar a biocompatibilidade da tela de polipropileno e do enxerto de submucosa intestinal de suínos, quando usados para o reparo de defeito criado na parede anterior de abdomen de ratos, que envolveu toda a sua espessura e extensão. MÉTODO: Vinte ratos Wistar foram divididos em dois grupos de 10 animais. Um defeito quadrangular, com 3,5cm de lado foi criado cirurgicamente na parede abdominal anterior dos 20 ratos. No primeiro grupo(grupo 1 este defeito foi reparado com submucosa de intestino delgado (SID, e no segundo grupo(grupo 2 com tela de polipropileno. Após 30 dias, os animais foram sacrificados. Além da avaliação macroscópica dos enxertos, realizou-se um estudo tensiométrico e microscópico. RESULTADOS: Os animais de ambos os grupos apresentaram aderências entre o implante e as estruturas intra-abdominais, todavia no grupo com a tela de polipropileno observou-se maior número de aderências entre a tela e as alças intestinais. A força máxima de ruptura foi significantemente maior no grupo de animais com a tela de polipropileno, todavia se corrigida pela espessura do enxerto, a tensão máxima foi maior no enxerto de submucosa porcina que na tela de polipropileno. A mesotelisação foi significativamente mais intensa no grupo da submucosa, assim como a deposição de colágeno. As reações granulomatosas de corpo estranho e inflamação crônica também foram mais intensas no grupo 1. CONCLUSÃO: A SID monstrou ser uma alternativa ao enxerto sintético no reparo de grandes defeitos da parede abdominal em ratos, com melhor mesotelisação e deposição de colágeno, sem aumento no número de complicações. A submucosa apresentou maior resistência por mm², apesar de ter se mostrado menos resistente quando considerada a força maneira absoluta.PURPOSE: The aim of the present study was compare the biocompatibility of a polypropylene mesh and a patch of porcine small intestinal submucosa (SIS when used to repair a

    Full Text Available El Síndrome del Intestino Irritable (SII, constituye un trastorno motor del intestino que cursa preferentemente con dolor abdominal y/o alteraciones en el ritmo intestinal, sin lesiones anatómicas, ni causas metabólicas o infecciosas que la justifiquen. Su incidencia entre la población general es alta y su tratamiento difícil y costoso. Desde la Psicología de la Salud se pretende un abordaje integral del síndrome con vocación interdisciplinar, donde interactúen profesionales médicos y psicólogos, y se reclama una aproximación conductual con base en el análisis funcional como medio para realizar una correcta evaluación, para lo cual los autores han diseñado un cuestionario específico de medida de severidad sintomática del SII, validado con población española.

    Marcelo Fernandes Rangel

    Full Text Available Os tumores do intestino delgado são raros e a maioria das lesões neoplásicas sintomáticas é maligna.Os neoplasmas benignos são um pouco mais freqüentes e ambos estão relacionados a um diagnóstico difícil, pois determinam queixas abdominais inespecíficas, comuns a uma grande variedade de afecções digestivas. Exames de imagem e endoscópicos podem ser úteis para o diagnóstico, mas freqüentemente não são conclusivos. Para os blastomas primários, a ressecção cirúrgica é a opção de escolha, porém, para os metastáticos, a terapêutica operatória deve ser reservada para os casos complicados por obstrução, hemorragia ou perfuração. O presente estudo tem por finalidade analisar retrospectivamente 13 casos de lesões malignas do intestino delgado, num período de 28 anos. Verificou-se maior incidência de tumores primários (69,2% e de linfomas (30,7%. Entre os secundários, as mestástases por adenocarcinoma foram as mais freqüentes (15,4%. Enterectomia segmentar foi o procedimento cirúrgico mais realizado (84,6% e a mortalidade hospitalar foi de 15,4%. A sobrevida de cinco anos foi nula para os pacientes portadores de metástases, enquanto que para os primários foi de 44,4%, sugerindo um melhor prognóstico para as neoplasias primitivas, independentemente do tipo histológico da neoplasia.

    2011-12-01

    Full Text Available Los tumores del estroma gastrointestinal fueron catalogados originalmente como otros tumores (leiomioma, leiomioblastoma o leiomiosarcoma, debido a su apariencia histológica similar; sin embargo, los avances en la biología molecular y la inmunohistoquímica, han permitido diferenciarlos de otras neoplasias digestivas, y definirlos como una entidad clínica e histopatológica propia. Se presenta un paciente, de sexo femenino, de la raza negra, de 79 años de edad, con dolor abdominal de 3 días de evolución, que se había iniciado en fosa ilíaca derecha y luego se mantuvo en bajo vientre, acompañado de vómitos, fatiga y decaimiento. Se decide intervenir quirúrgicamente y se lleva al salón de operaciones con el diagnóstico de una apendicitis aguda, del muñón, tipo oclusiva en el anciano, sin descartar una oclusión por bridas. Al realizar laparotomía se encuentra sangre libre en cavidad que no coagula, y se observó tumor hemorrágico, pediculado, muy móvil, hacia íleon terminal. Se realiza exéresis de este, se resecan aproximadamente 5 cm de intestino delgado y se realiza sutura termino-terminal posteriormente. Se realizó amplia toillette de la cavidad peritoneal y el cierre habitual, con evolución satisfactoria, y con alta a los 7 días. Se mantiene asintomática al año y medio de operada, y la biopsia arrojó tumor de intestino delgado, de bajo grado de malignidad, de 5 cm de diámetro.The tumors of the gastrointestinal stroma were originally classified as other type of tumors (leiomyoma, leiomyobastoma or leiomyosarcoma due to it similar histological appearance; however, the advances in the molecular biology and the immunohistochemistry have allowed its differentiation of other digestive neoplasms and to define them as an own clinical and histopathological entity.

    Full Text Available RACIONAL: Avanços da biotecnologia e o desenvolvimento de novas drogas imunossupressoras melhoraram os resultados do transplante de intestino delgado. Esse transplante é atualmente indicado para casos especiais da falência intestinal. OBJETIVO: A presente revisão realça os recentes desenvolvimentos na área do transplante de intestino delgado. MATERIAL E MÉTODO: Mais de 600 publicações de transplante de intestino delgado foram revisadas. O desenvolvimento da pesquisa, novas estratégias de imunossupressão, monitorização do enxerto e do receptor, e avanços na técnica cirúrgica são discutidos. RESULTADOS: Realizaram-se cerca de 700 transplante de intestino delgado em 55 centros: 44% intestino-fígado, 41% enxerto intestinal isolado e 15% transplante multivisceral. Rejeição e infecção são as principais limitações desse transplante. Sobrevida de 5 anos na experiência internacional é de 46% para o transplante de intestino isolado, 43% para o intestino-fígado e de cerca de 30% para o transplante multivisceral. Sobrevidas prolongadas são mais freqüentes nos centros com maior experiência. Em série de 165 transplantes intestinais na Universidade de Pittsburgh, PA, EUA, foi relatada sobrevida do paciente maior do que 75% no primeiro ano, 54% em 5 anos e 42% em 10 anos. Mais de 90% desses pacientes assumem dieta oral irrestrita. CONCLUSÃO: O transplante de intestino delgado evoluiu de estratégia experimental para uma alternativa viável no tratamento da falência intestinal permanente. Promover o refinamento da terapia imunossupressora, do manejo e prevenção de infecções, da técnica cirúrgica e da indicação e seleção adequada dos pacientes é crucial para melhorar a sobrevida desse transplante.BACKGROUND: Significant progress has been made in clinical small bowel transplantation over the last decade mainly due advances in biotechnology and new immunosuppressive regiments.

    Vivian R. Mena Miranda

    Full Text Available El intestino se considera el mayor reservorio de gérmenes del organismo, aunque también desempeña un papel protagónico en la nutrición y regulación inmunológica. La isquemia intestinal es un factor predisponente de la disfunción múltiple de órganos (DMO, pues al redistribuirse el flujo sanguíneo para garantizar la perfusión de los órganos vitales se produce la liberación de mediadores de la inflamación y de endotoxinas, capaces de desencadenar un síndrome de respuesta inflamatoria sistémica con severas alteraciones hemodinámicas. La perfusión y nutrición enteral precoz se siguen considerando los 2 aspectos más importantes en la prevención del intestino de estrés.

OBJETIVO: Investigar a associação entre obesidade geral e abdominal com HA e identificar a sensibilidade e especificidade desses indicadores para detectar HA em adolescentes. MÉTODOS: A amostra consistiu em 1.021 adolescentes com idade de 10-17 anos. 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.

    Full Text Available Resumo: O sucesso na manutenção de uma espécie depende de vários fatores entre eles a eficiência digestiva, sendo assim parâmetros morfométricos do tubo digestório são necessários para o conhecimento dos processos digestivos dos alimentos no organismo animal além de indicar a preferência alimentar de uma espécie. Este trabalho visou descrever morfologicamente os intestinos delgado e grosso, órgãos do sistema digestório de representantes da ordem Xenarthra a fim de fornecer subsídios para a avaliação da dieta e realização de procedimentos clínicos nestes animais, sejam eles de vida livre ou de cativeiro. Foram utilizados 7 espécimes entre preguiças-de-coleira (Bradypus torquatus, tatu-verdadeiro (Dasypus novemcinctus e tamanduá-bandeira (Myrmecophaga tridactyla. Todos as amostras foram processadas seguindo procedimentos de rotina efetuados nos laboratórios de Anatomia Animal e Histologia da FZEA/USP. Os intestinos de B. torquatus se apresentaram curtos e simples, enquanto que nos exemplares de D. novemcintus e M. tridactyla o intestino era longo e com algumas peculiaridades. No duodeno de todos os espécimes notamos a presença das glândulas de Brünner e estruturas para aumentar a superfície de absorção. Apenas em preguiças, o mesentério mantém o jejuno preso à parede dorsal da cavidade abdominal. O íleo representou a menor porção nas preguiças e tatus, exceto em tamanduáque apresentava o íleo como a maior parte depois do jejuno. O ceco em tatus e tamanduás apresentavam tamanho considerável e a presença de glândulas na mucosa, nestas espécies destacamos a funcionalidade do ceco, uma vez que este se apresentou repleto de restos alimentares. Na mucosa do cólon de todos os espécimes, haviam criptas de Lieberkühn, sendo mais numerosas em D. novemcinctus e M. tridactyla. Apenas em B. torquatus, o reto apresentou maior diâmetro e rigidez em relação ao cólon. No reto de todas as espécies estudadas, a

    Full Text Available A despeito de o avestruz (Struthio camelus compartilhar muitas adaptações evolucionárias presentes em outras aves, estes animais apresentam algumas características anatômicas peculiares, como é o caso do seu tubo digestivo em que o cólon é maior que o ceco. Há algum tempo, essa ave tem sido explorada econômicamente e principalmente como fonte alternativa de proteína animal na alimentação humana. O presente trabalho analisou os aspectos histológicos do intestino de avestruzes produzidos em boas condições de manejo ambiental e nutricional. Foram utilizados 13 avestruzes, com 18 a 30 meses de idade, provenientes da empresa Brasil Ostrich, e encaminhados para o abate no Abatedouro Escola da Universidade de São Paulo, Campus Administrativo de Pirassununga. Os animais foram abatidos com pistola pneumática e, após a sangria e evisceração, foram colhidas amostras de diferentes segmentos do intestino: duodeno, jejuno, íleo e ceco duplo. Os materiais foram processados, corados pela técnica de hematoxilina-eosina (H-E e examinados em microscopia de campo claro. Os resultados obtidos revelaram que as vilosidades estão presentes no duodeno, porém, não existem no ceco. Dos quatro segmentos intestinais examinados, o ceco foi o que apresentou maior número de células caliciformes. Os nódulos linfáticos e os linfócitos foram observados em todos os segmentos examinados. No ceco, os nódulos linfáticos se agregam para constituir a placa de Peyer. O plano histológico dos segmentos intestinais examinados seguiu o padrão observado nos mamíferos domésticos e em outras aves. O conhecimento da histologia dos intestinos desses animais pode oferecer subsídios para a avaliação comparativa de procedimentos de manejo ambiental e nutricional que possam aumentar os níveis de produção e produtividade dessa atividade pecuária.

  18. 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 Os objetivos do presente trabalho foram estudar a anatomia funcional e a morfometria comparativas nos intestinos médio e no reto, do peixe Teleostei, surubim, Pseudoplatystoma coruscans (Agassiz, 1829 (Siluriformes, Siluroidei, Pimelodidae, de hábito alimentar carnívoro, em duas classes de tamanho, visando fornecer referência à nutrição para o ajuste de diferentes sistemas de alimentação artificial para essa espécie nativa. Por meio destes estudos concluiu-se que o intestino do surubim, sob o ponto de vista morfológico, deve ser denominado, de intestino médio e reto, devido a presença da valva ileorretal e da invaginação valvar intestinal entre esses segmentos. Em relação ao padrão de enrolamento do intestino, apesar do plano geral do intestino médio e do reto ter sido mantido, as alças do intestino médio apresentaram arranjo indefinido, não tendo sido determinado um arranjo-padrão para a espécie. O arranjo intestinal é compatível ao da maioria de peixes carnívoros, ou predominantemente carnívoro, uma vez que seu intestino é quase retilíneo; contudo, as circunvoluções das alças finais do intestino médio talvez possam ser vistas como adaptações a um possível regime onívoro, preferencialmente carnívoro. As pregas intestinais encontram-se mais complexas e desenvolvidas no intestino dos exemplares da segunda classe de tamanho. Procurando estabelecer relações entre o arranjo das pregas das mucosas e a velocidade de transporte do alimento no intestino médio da espécie estudada, sugere-se que o padrão longitudinal, com numerosas anastomoses retardam o avanço do alimento em sentido aboral, o que possibilita maior período digestivo e, conseqüentemente, maior aproveitamento dos nutrientes, pela exposição do material alimentar à mucosa intestinal por período maior, além de contribuir para a preparação do bolo fecal. As pregas da mucosa próxima ao ânus têm direção longitudinal, sugerindo auxílio na

  9. Abdominal trauma

    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

    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.

    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.

  20. Abdominal emergencies

    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

Dentre os vários exames alguns testes fisiológicos ano retais avaliam a função esfincteriana e sensibilidade retal OBJETIVO: Verificar se existem diferenças entre as manometrias anais dos pacientes com constipação funcional e síndrome do intestino irritável. MÉTODO: Trata-se de estudo de 55 manometrias e testes de sensibilidade anais realizadas em pacientes atendidos no ambulatório de Fisiologia Anal do Serviço de Clínica Cirúrgica do Hospital Universitário de Taubaté com diagnóstico de constipação intestinal ou síndrome do intestino irritável no período de janeiro de 2006 a maio de 2007. Todos os pacientes possuíam colonoscopia a normal e foram incluídos nos critérios diagnósticos de Roma II para Constipação Funcional e Síndrome do Intestino Irritável. As manometrias foram realizadas com aparelho ALACER, de perfusão com 8 canais. RESULTADOS: Não foram encontradas diferenças entre as manometrias quanto às pressões de repouso, contração e evacuação, assim como nos valores de sensibilidade retal. Encontramos diferenças quanto à dor abdominal desencadeada nos pacientes com síndrome do intestino irritável no momento do volume máximo tolerável em que 69,2% destes pacientes apresentaram dor abdominal. CONCLUSÃO: Os pacientes com a síndrome do intestino irritável apresentam dor à distensão da ampola retal, que não ocorre nos pacientes constipados, na aferição do volume máximo tolerável, não houve diferença em relação aos outros dados da manometria.INTRODUCTION: In some patients the irritable bowel syndrome and the functional constipation is confuse, mainly when the predominant symptom in the irritable bowel syndrome is the constipation.

    Full Text Available A anastomose íleo-retal término-terminal, após ressecção do intestino grosso, foi realizada em 13 suínos Large White x Landrace, com média de 15kg de peso e em torno de 67 dias de idade, sob anestesia pelo halotano, em circuito semifechado. A laparotomia constou de incisão na região paramediana esquerda, no sentido da bainha prepucial, seguida de incisão na linha branca. O intestino grosso foi liberado das suas relações com o intestino delgado e do mesentério até a sua posição relativa aos ligamentos laterais da bexiga. O íleo e o reto foram seccionados tão próximo quanto possível da válvula íleocecal e a 10 e 12cm do esfíncter anal, respectivamente, e as ligaduras dos vasos mesentéricos foram feitas em massa, a intervalos de 2-3cm. O intestino grosso foi removido, procedendo-se a anastomose íleo-retal, mediante sutura seromucosa, por pontos simples separados tipo Swift, com fio de seda preto n° 0, a 2-3mm das bordas, com os nós posicionados para o lume do órgão. Em suínos jovens, a anastomose íleo-retal após ressecção do intestino grosso é tecnicamente exeqüível e permite a sobrevivência dos animais por período adequado até sua utilização em pesquisas sobre digestibilidade. O material e o tipo de sutura utilizados permitiram adequada justaposição das bordas intestinais da anastomose, compensando pequenas diferenças entre os diâmetros do íleo e do reto. A remoção do intestino grosso conduziu a adaptações morfofuncionais marcantes, e a dilatação do segmento distal do intestino delgado constituiu a alteração macroscópica mais significativa. Observou-se redução no desenvolvimento e no peso corporal dos animais adaptados à nova condição fisiológica.

The patient presented with anemia and an abdominal mass, and the symptoms progressed until a final diagnosis was made nine months later. A plain abdominal x-ray showed the presence of gas outside the bowel, in the right hypochondrium. The double contrast barium enema showed a sublevel displacement of the hepatic flexure and diverticula. An abdominal ultrasound revealed a heterogeneous expansive lesion below the liver containing gas, and a computed tomography of the abdomen revealed an excavated mass below the liver containing liquid, that was not filled by contrast medium. The patient was submitted to a right hemicolectomy with ileocoloanastomosis and the histopathological analysis of the excised material revealed a leiomyosarcoma of the ascending colon. (author)

Foram conduzidos estudos anatomofuncionais e morfométricos nos intestinos médio e posterior e nos cecos pilóricos dessa espécie com hábito alimentar onívoro. Constatou-se, por meio destes estudos, que o padrão de enrolamento das alças intestinais em arranjo em N apresentou, na segunda classe de tamanho, freqüentes variações no intestino médio, mas foi compatível com os de outras espécies de hábitos alimentares similares. Os estudos da morfometria mostraram que o comprimento total do intestino e das alças intestinais e seus calibres, provavelmente, exercem função específica na absorção dos nutrientes. As relações entre o arranjo das pregas da mucosa e a velocidade de transporte do alimento no intestino médio sugerem que os padrões transversal e oblíquo retardam o avanço do alimento em sentido aboral, possibilitando maior período digestivo e melhor aproveitamento dos nutrientes, contribuindo para a preparação do bolo fecal. O comprimento e o calibre dos cecos pilóricos aumentam com o desenvolvimento do peixe, e o seu padrão de mucosa possui características anatômicas semelhantes às do intestino.

    Full Text Available Según las historias elegidas, un medio de comunicación de masas construye realidades sociales diferentes, algunas de las cuales contribuyen a pensar acerca de cuestiones relevantes mientras otras refieren a materias de orden menor.El comunicador puede elegir al menos tres caminos: a Dedicarse a temáticas que conciten interés masivo por más que se agoten en poco tiempo, tal la situación contractual del hábil futbolista de Boca Juan Román Riquelme. b Aludir a asuntos como la insuficiente asignación de fondos para investigación científica, que no obstante ser un tema de conversación menos extendido impactará más en el porvenir del país que el contrato de un jugador.c Asumir que la vida no es únicamente ciencia ni fútbol, lo cual no da derecho a igualar la trascendencia de la una a la del otro.En cada una de las opciones es menester considerar que el modo en que una historia se relata condiciona su percepción. Y recordar que, al tiempo que un cantante expresa "cómo dueles en los labios" y genera pesar evocativo o imaginativo, otro, que emite sonidos que permiten escuchar "Tú, que vienes y pasas como un huracán", apenas si deja la impresión de que el huracán es un vientito.

    Full Text Available A criação de jacaré-do-Pantanal tem se consolidado no estado de Mato Grosso como atividade alternativa e legal para as propriedades rurais na área de ocorrência natural da espécie, coibindo a caça predatória e colaborando na preservação da espécie. A racionalização do processo produtivo na criação de jacaré é uma ação relativamente nova, que permite obter pele de melhor qualidade e de utilização integral, diferentemente daquelas oriundas de animais da natureza. Considerando a importância dos intestinos como sede dos principais eventos relacionados à obtenção de nutrientes para o metabolismo corpóreo, este trabalho teve por objetivo caracterizar qualitativa e quantitativamente a mucosa dos intestinos delgado e grosso de jacaré-do-Pantanal jovens. Para a caracterização ao microscópio óptico da estrutura da parede intestinal e da histometria da mucosa foram coletadas amostras intestinais de 16 animais, sendo três deles também destinados ao estudo histoquímico. As amostras foram obtidas de cinco regiões, sendo quatro do intestino delgado e uma do intestino grosso. Elas foram fixadas em solução de Bouin, processadas de acordo com técnicas preconizadas para inclusão em parafina. Cortes histológicos semi-seriados (quatro micrômetros foram obtidos e o material foi desparafinizado, hidratado e corado pela hematoxilina-eosina para a descrição geral e estudo histométrico, que consistiu da mensuração da freqüência das vilosidades intestinais; dos comprimentos do epitélio e da lâmina própria da mucosa e da espessura da mucosa. Na análise estatística foi empregada a análise de variância e Teste de Tukey. Para o estudo histoquímico foram utilizadas a reação ao ácido periódico de Schiff, alcian blue pH 1,0 contrastado com hematoxilina e alcian blue pH 2,5 conjugado ao ácido periódico de Schiff. Para a descrição das estruturas histológicas foi empregada a terminologia disponível na Nomina

O paciente iniciou o quadro com anemia e massa abdominal, e a evolução dos sintomas até o diagnóstico final foi de nove meses. Na radiografia simples do abdome havia presença de coleção aérea localizada no hipocôndrio direito, fora da topografia de alças; no clister opaco com duplo contraste foi demonstrado deslocamento inferior da flexura hepática e divertículos. A ultra-sonografia abdominal mostrou lesão expansiva heterogênea, com gás no seu interior, de localização sub-hepática. A tomografia computadorizada do abdome revelou massa escavada com nível líquido, sub-hepática, que não se impregnou pelo meio de contraste. Foi realizada hemicolectomia direita com ileocoloanastomose, e o diagnóstico histopatológico foi de leiomiossarcoma de cólon ascendente.The authors report a case of a 49-year-old male patient with leiomyosarcoma of the ascending colon. The patient presented with anemia and an abdominal mass, and the symptoms progressed until a final diagnosis was made nine months later. A plain abdominal x-ray showed the presence of gas outside the bowel, in the right hypochondrium. The double contrast barium enema showed a sublevel displacement of the hepatic flexure and diverticula. An abdominal ultrasound revealed a heterogeneous expansive lesion below the liver containing gas, and a computed tomography of the abdomen revealed an excavated mass below the liver containing liquid, that was not filled in by contrast medium. The patient was submitted to a right hemicolectomy with ileocoloanastomosis and the histopathological analysis of the excised material revealed a leiomyosarcoma of the ascending colon.

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

    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

A confirmação desta doença só é possível através da análise histopatológica de um fragmento obtido por algum procedimento invasivo, pois não existe até o momento, nenhum marcador clínico seguro. OBJETIVO: Relatar a experiência com as manifestações clínicas e o tratamento cirúrgico em pacientes com endometrioma de parede abdominal. MÉTODO: Análise retrospectiva das pacientes operadas por endometrioma de parede abdominal, dando ênfase aos dados relativos à idade, sintomas, cesariana prévia, relação dos sintomas com o ciclo menstrual, exames físicos e complementares, tratamento cirúrgico, evolução pósoperatória e resultado histopatológico dos espécimes. RESULTADOS: Foram operadas 14 pacientes no período estudado, com idade entre 28 e 40 anos. A presença de massa e dor local que piorava durante a menstruação foram as queixas principais. Ultrassonografia e tomografia computadorizada foram exames importantes em localizar precisamente a doença. O tratamento cirúrgico foi exérese ampla da tumoração e dos tecidos comprometidos. As pacientes evoluíram satisfatoriamente e o histopatológico confirmou a suspeita de endometrioma de parede abdominal em todos os casos. CONCLUSÂO: Foi nítida a relação entre cesariana prévia e endometrioma de parede abdominal e estudos ultrassonográficos e tomográficos auxiliaram a planejar a abordagem cirúrgica permitindo a exérese da tumoração e de todos os tecidos adjacentes comprometidos.BACKGROND: The exact incidence of endometriosis in the general population is unknown. Confirmation of this disease is only possible by histopathological analysis of a fragment obtained by some invasive procedure, because there is so far, no clinical secure marker.

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.

  18. Abdominal emergencies in pediatrics.

    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.

    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.

    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

    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

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.

    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 History of present illness: A 69-year-old male with poorly controlled hypertension presented with 1 hour of severe low back pain that radiated to his abdomen. The patient was tachycardic and had an initial blood pressure of 70/40. He had a rigid and severely tender abdomen. The patient’s history of hypertension, abnormal vital signs, severity and location of his pain were suspicious for a ruptured abdominal aortic aneurysm (AAA. Therefore, a computed tomography angiogram (CTA was ordered. Significant findings: CTA demonstrated a ruptured 7.4 cm infrarenal abdominal aortic aneurysm with a large left retroperitoneal hematoma. Discussion: True abdominal aortic aneurysm is defined as at least a 3cm dilatation of all three layers of the arterial wall of the abdominal aorta.1 An estimated 15,000 people die per year in the US of this condition.2 Risk factors for AAA include males older than 65, tobacco use, and hypertension.1,3,4 There are also congenital, mechanical, traumatic, inflammatory, and infectious causes of AAA.3 Rupture is often the first manifestation of the disease. The classic triad of abdominal pain, pulsatile mass, and hypotension is seen in only 50% of ruptured AAAs.5 Pain (abdominal, groin, or back is the most common symptom. The most common misdiagnoses of ruptured AAAs are renal colic, diverticulitis, and gastrointestinal hemorrhage.6 Bedside ultrasonography is the fastest way to detect this condition and is nearly 100% sensitive.1 One study showed that bedside ultrasounds performed by emergency physicians had a sensitivity of .94 [95% CI = .86-1.0] and specificity of 1 [95% CI = .98-1.0] for detecting AAAs.7 CTA has excellent sensitivity (approximately 100% and yields the added benefit of facilitating surgical planning and management.1 Without surgical treatment, a ruptured AAA is almost uniformly fatal, and 50% of those who undergo surgery do not survive.1 Early resuscitation and coordination with vascular surgery should be

    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

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.

  15. [Abdominal catastrophe--surgeon's view].

    Abdominal catastrophe is a serious clinical condition, usually being a complication arising during treatment of intraabdominal nontraumatic disorders or abdominal injuries. Most commonly, inflamation- secondary peritonitis, is concerned. Abdominal catastrophe also includes secondary signs of sepsis, abdominal compartment syndrome and enterocutaneous fistules. Most septic abdominal disorders which show signs of abdominal catastrophy, require surgical intervention and reinterventions--planned or "on demand" laparotomies. During the postoperative period, the patient requires intensive care management, including steps taken to stabilize his/hers condition, management of sepsis and metabolic and nutritional support measures, as well as adequate indication for reoperations. New technologies aimed at prevention of complications in laparostomies and to improve conditions for final laparotomy closure are used in phase procedures for surgical management of intraabdominal infections. Despite the new technologies, abdominal catastrophe has higher morbidity and lethality risk rates.

    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.

    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.

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

    Prefumo, Federico; Izzi, Claudia

    2014-04-01

    The most common fetal abdominal wall defects are gastroschisis and omphalocele, both with a prevalence of about three in 10,000 births. Prenatal ultrasound has a high sensitivity for these abnormalities already at the time of the first-trimester nuchal scan. Major unrelated defects are associated with gastroschisis in about 10% of cases, whereas omphalocele is associated with chromosomal or genetic abnormalities in a much higher proportion of cases. Challenges in management of gastroschisis are related to the prevention of late intrauterine death, and the prediction and treatment of complex forms. With omphalocele, the main difficulty is the exclusion of associated conditions, not all diagnosed prenatally. An outline of the postnatal treatment of abdominal wall defects is given. Other rarer forms of abdominal wall defects are pentalogy of Cantrell, omphalocele, bladder exstrophy, imperforate anus, spina bifida complex, prune-belly syndrome, body stalk anomaly, and bladder and cloacal exstrophy; they deserve multidisciplinary counselling and management.

    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.

    Dissections due to deceleration trauma are rarely limited to the infradiaphragmal aorta (only 2-3%) and are usually lethal. Here we report the unusual course of an abdominal aortic dissection with aneurysmatic enlargement of the false lumen. Based on diagnostic imaging, a therapeutic stent application was planed in order to close the entry and to prevent rupture. During the intervention sondation of the false lumen revealed that the left renal artery had a reentry. Due to the complexity of the entry - reentry situation of the left renal artery the intervention was not possible, and the patient had to undergo vascular surgery. (orig.) [de

    The authors describe three cases of intraabdominal fibromathosis: two cases with intraperithoneal location and another one with retroperithoneal location. All of them are benign noncapsulated tumours of the fibrous tissue with tendancy to local recurrence. Abdominal fibromathosis may determine any form of acute or chronic digestive manifestations. Only to the accuracy of the histo-pathological examination is due the diagnosis between fibromathosis and fibrosarcoma, reactive fibrosis, mixoma and nodular fasceitis. The surgical excision must not be economical and the association with radiant therapy must also be considered.

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

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.

    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.)

    Full Text Available Las reformas económicas aplicadas en el medio rural, que acompañaron la ratificación del TLCAN en 1994 y más concretamente la reforma de la ropiedad social de la tierra en los ejidos en 1992, han alterado radicalmente las condiciones de reproducción social de las familias rurales del sur del estado de Veracruz, México. Estos cambios han provocado que migren por largos periodos las jóvenes generaciones hacia la frontera norte y Estados Unidos, a diferencia de lo que ocurría antes de la década de los noventa, cuando la migración se circunscribía al Golfo de México. Tomando como base una encuesta sociodemográfica y sobre tenencia de la tierra realizada en 1999, los autores de este texto sostienen que las familias rurales, al no poder mantenerse con los recursos domésticos y locales en su entorno, se ven forzadas a poner en marcha una nueva organización, que se asemeja a una economía de archipiélago, entre los lugares donde se instalan las jóvenes generaciones. En este contexto, el artículo revela cómo se ponen en juego y se redefinen las relaciones intergeneracionales de solidaridad, así como los modos de transmisión y de circulación del patrimonio agrario, tanto en el seno de la comunidad agraria (ejido como en las mismas familias.

    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.

    2012-06-01

    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.

    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.

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

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

    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.

    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.

MÉTODOS: Utilizaram-se 18 ratos do tipo Wistar, aleatoriamente distribuídos em três grupos. 1-Controle, 2-Simulação e 3-Isquemia/Reperfusão. Neste último, realizou-se isquemia no íleo, por 60 minutos, seguida de reperfusão por 30 minutos. No grupo 2 efetuou-se apenas uma laparotomia. Foram retirados, de todos os animais, segmentos do intestino com e sem reperfusão, além do pulmão e rim direitos para exame com microscopia óptica. A atividade da catalase foi aferida em espectrofotômetro ajustado para 240 nm. Utilizaram-se os testes estatísticos Mann e Whitney e Kruskal Wallis. RESULTADOS: Observou-se aumento significante (p < 0.05, da atividade da catalase nas porções do intestino isquemiado e não isquemiado, além do pulmão. Houve redução da atividade enzimática no rim. No grupo com reperfusão observaram-se alteração nas vilosidades, infiltrado inflamatório em todas as vísceras, além de áreas de atelectasia pulmonar. CONCLUSÃO: O estresse oxidativo intestinal, em ratos, causa alterações bioquímicas à distância com mobilização dos mecanismos de defesa antioxidante pulmonar, em segmento intestinal não isquemiado e no rim, com esgotamento precoce das reservas deste último, no entanto, sem lesão celular relevante, destas vísceras.

Materiales y métodos. 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.

    Full Text Available Abstract Background Episiotomy is the surgical enlargement of the vaginal orifice by an incision of the perineum during the second stage of labor or just before delivery of the baby. During the 1970s, it was common to perform an episiotomy for almost all women having their first delivery, ostensibly for prevention of severe perineum tears and easier subsequent repair. However, there are no data available to indicate if an episiotomy should be midline or medio-lateral. We compared midline versus medio-lateral episiotomy for complication such as extended perineal tears, pain scores, wound infection rates and other complications. Methods We conducted a prospective cohort including 1,302 women, who gave birth vaginally between April 2005 and February 2006 at Srinagarind Hospital – a tertiary care center in Northeast Thailand. All women included had low risk pregnancies and delivered at term. The outcome measures included deep perineal tears (including perineal tears with anal sphincter and/or rectum tears, other complications, and women's satisfaction at 48 hours and 6-weeks postpartum. Results In women with midline episiotomy, deep perineal tears occurred in 14.8%, which is statistically significantly higher compared to 7% in women who underwent a medio-lateral episiotomy (p-value 3,500 g and forceps extraction. Conclusion Midline compared to medio-lateral episiotomy resulted in more deep perineal tears. It is more likely deep perineal tears would occur in cases with additional risk factors.

    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

    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)

    To improve the prognosis of patients with abdominal trauma. Between January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years (ranging from 3-82 years). All abdominal traumas consisted of closed traumas (360 cases, 86.7%) and open traumas (55 cases, 13.3%). A total of 407 cases (98.1%) were fully recovered from trauma and the other 8 cases (1.9%) died of multiple injuries. The mean injury severity score (ISS) of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds (6 cases), pancreatic fistula (2 cases) and intestinal fistula (1 case). All these postoperative complications were cured by the conservative treatment. Careful case history inquisition and physical examination are the basic methods to diagnose abdominal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

    Although the number of elective operations for abdominal aortic aneurysms (AAA) is increasing, the sex- and age-standardised mortality rate of AAAs continues to rise, especially among men aged 65 years or more. The lethality of ruptured AAA continues to be 80-95%, compared with 5-7% by elective surgery of symptomfree AAA. In order to fulfil all WHO, European, and Danish criteria for screening, a randomised hospitalbased screening trial of 12,639 65-73 year old men in Viborg County (Denmark) was initiated in 1994. It seemed that US screening is a valid, suitable and acceptable method of screening. The acceptance rate was 77%, and 95% accept control scans. Furthermore, persons at the highest risk of having an AAA attend screening more frequently. We found that 97% of the interval cases developed from aortas that initially measured 2.5-2.9 cm - i.e. approx. only 5% attenders need re-screening at 5-year intervals. Two large RCTs have given clear indications of operation. Survivors of surgery enjoy the same quality of life as the background population, and only 2-5% of patients refuse an offer of surgery. Early detection seems relevant since the cardiovascular mortality is more than 4 times higher in AAA patients without previous hospital discharge diagnoses due to cardiovascular disease than among similar men without AAA. The absolute risk difference after 5 years was 16%. So, they will benefit from general cardiovascular preventive action as smoking cessation, statins and low-dose aspirin, which could inhibit further AAA progression. All 4 existing RCTs point in the same direction, viz. in favour of screening of men aged 65 and above. We found that screening significantly reduced AAA-related mortality by 67% within the first five years (NNT = 352). Restriction of screening to men with previous cardiovascular or pulmonary hospital discharge diagnoses would request only 27% of the relevant male population study to be invited, but would only have prevented 46.7% of the

    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

    Full Text Available Introduction. We present a case of a sports injury. The initial presentation and clinical examination belied serious intra-abdominal injuries. Case Presentation. A 16-year-old male patient came to emergency department after a sports-related blunt abdominal injury. Though on clinical examination the injury did not seem to be serious, FAST revealed an obscured splenorenal window. The CT scan revealed a large left renal laceration and a splenic laceration that were managed with Cook coil embolization. Patient remained tachycardic though and had to undergo splenectomy, left nephrectomy, and a repair of left diaphragmatic rent. Patient had no complication and had normal renal function at 6-month followup. Conclusion. The case report indicates that management of blunt intra-abdominal injury is complicated and there is a role for minimally invasive procedures in management of certain patients. A great deal of caution is required in monitoring these patients, and surgical intervention is inevitable in deteriorating patients.

    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)

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

    In spite of many advances in medicine, anesthetic technique and surgical managements, pulmonary problems are the most frequent postoperative complications, particularly after abdominal surgery. As postoperative pulmonary complications, atelectasis, pleural effusion, pneumonia, chronic bronchitis and lung abscess can be occurred. This study include evaluation of chest films of 2006 patients (927 male, 1079 female), who had been operated abdominal surgery from Jan. 1979 to June, 1980 in the Hanyang university hospital. The results were as follows: 1. 70 cases out of total 2006 cases (3.5%) developed postoperative chest complications, 51 cases (5.5%) in male, 19 cases (1.8%) in female. 2. The complication rate was increased according to the increase of age. The incidence of the postoperative complications over 40 years of age was higher than the overall average complications rate. 3. The most common postoperative pulmonary complication was pleural effusion, next pneumonia, atelectasis and pulmonary edema respectively. 4. The complication rate of the group of upper abdominal surgery is much higher than the group of lower abdominal surgery. 5. Complication rate was increased according to increase of the duration of operation. 6. There were significant correlations between the operation site and side of the complicated hemithorax

    Full Text Available De acuerdo con las estrategias internacionales en materia de salud y medio ambiente, los Ministerios de Sanidad y de Medio Ambiente pusieron en marcha en 2007 los mecanismos necesarios para la elaboración del Plan Nacional de Salud y Medio Ambiente. El primer paso ha sido la firma de un acuerdo de encomienda de gestión con el Instituto de Salud Carlos III para que éste diseñara las bases sobre las que sustentar el plan. El comité científico creado al efecto ha redactado un informe de bases para lo que ha contado con el concurso de un nutrido grupo de expertos. Las propuestas que se recogen en el informe constituyen el contenido del presente trabajo. Las propuestas hacen referencia a los ítems considerados prioritarios en la Estrategia Europea de Medio Ambiente y Salud, es decir, cáncer, alteraciones endocrinas, trastornos del desarrollo neurológico y enfermedades respiratorias, y se organizan en torno a los principales factores de riesgo ambiental para la salud: agua, compuestos químicos tóxicos persistentes, campos electromagnéticos, radicaciones ionizantes, ruido y cambio climático y temperaturas extremas. Para dar consistencia al plan se señalan algunas medidas imprescindibles que aseguren su viabilidad administrativa, política, técnica y financiera. Para darle coherencia, se arbitran unas líneas prioritarias comunes y unas estrategias metodológicas compatibles. Para darle forma, se señalan los programas nacionales que deberán implementarse y que deberán basarse en esa consistencia y coherencia. Más que entrar a concretar lo que se debe hacer —materia propia del futuro plan—, el informe señala cómo se debe hacer para lograr resultados exitosos.

    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

    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.

    Congenital abdominal wall defects that are located outside of the anterior wall are extremely rare and difficult to classify because there are no well accepted guidelines. There are two regions outside of the anterior wall: the flank or lateral wall; and the lumbar region. We report the case of a patient with an oval 3 cm-diameter hernia defect located above the anterior axillary line, which affects all layers of the muscular wall. An anorectal malformation consisting of a recto-vestibular fistula was also identified, and chest X-ray showed dextrocardia. The suggested treatment is repair of the defect before 1 year of age. Given that the anomalies described may accompany lateral abdominal wall hernia, it is important to diagnose and treat the associated defects. © 2016 Japan Pediatric Society.

  2. Appendicitis following blunt abdominal trauma.

    2017-09-01

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

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

    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.

    If morbidity and mortality are to be reduced in patients with penetrating abdominal trauma, first priority goes to prompt and accurate determination of peritoneal penetration and identification of the need for surgery. In this setting, laparoscopy may have an important impact on the rate of negative or non-therapeutic laparotomies. We analyzed indications and patient selection criteria for laparoscopy in penetrating trauma along with outcomes. The analysis focused on identification of peritoneal penetration and injuries to the diaphragm, small intestine, and mesentery. Results from the early phase of laparoscopy were compared with those from recent decades with more advanced laparoscopic equipment and instruments and more experienced surgeons. A systematic review of the role of laparoscopy in penetrating abdominal trauma shows a sensitivity ranging from 66.7 to 100%, specificity from 33.3 to 100% and accuracy from 50 to 100%. Publications from the 1990s found trauma laparoscopy to be inadequate for detecting intestinal injuries and so to lead to missed injuries. Twenty-three of the 50 studies including the most recent ones report sensitivity, specificity, and accuracy of 100%. Laparoscopy is more cost effective than negative laparotomy. Laparoscopy can be performed safely and effectively on stable patients with penetrating abdominal trauma. The most important advantages are reduction of morbidity, accuracy in detecting diaphragmatic and intestinal injuries, and elimination of prolonged hospitalization for observation, so reducing the length of stay and increasing cost effectiveness.

    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.

    The aim of this study was to describe the MRI features of abdominal tuberculous lymphadenopathy. MRI studies of 13 patients with abdominal tuberculous lymphadenopathy were reviewed with regard to anatomic distribution and size. Signal intensities, in relation to abdominal wall muscle, on unenhanced T1- and T2-weighted images and patterns of contrast enhancement of lymphadenopathy were evaluated in each patient. In each patient, the largest lymph node with the same imaging characteristic was evaluated. The upper paraaortic region was the most common site of involvement (n=12 patients), followed by the lesser omentum (n=10 patients), the anterior pararenal space (n=9 patients), the lower paraaortic area (n=8 patients), the small bowel mesentery (n=6 patients), the greater omentum (n=2 patients) and the originating site of the inferior mesenteric artery (n=2 patients). The mean lymph node size was 1.8 cm (range 0.5-5 cm). The overall mean lymph node number per patient was 16 (range 2-50). A total of 41 lymph nodes were evaluated in 13 patients. On T2-weighted images, 40 lesions were hyperintense and one lesion was isointense. Nine hyperintense lesions showed a hypointense peripheral rim and seven internal heterogeneity. Perinodal T2-hyperintensity was present in 23 lesions. The latter finding was valid for all patients. On T1-weighted images, 30 lesions were hypointense and 11 isointense. Nine hypointense lesions demonstrated a hyperintense peripheral rim, and six were heterogeneous. Contrast-enhanced fat-suppressed T1-weighted images demonstrated predominant peripheral enhancement in 28 lesions: (1) peripheral uniform, thin (n=19); (2) thick irregular, complete (n=3); and (3) conglomerate group of nodes showing peripheral and central areas of rim enhancement (n=6). Heterogeneous and homogeneous enhancement was present in ten and three lesions, respectively.

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.

    Characteristics of abdominal acupuncture are analyzed through three aspects of inheriting and innovation, collaborated research as well as international visual field. It is pointed that abdominal acupuncture is based on clinical practice, focuses on enhancing the therapeutic effect and expending the clinical application. It also promots the thinking on how to recall the tradition and how to inherit tradition availably. The modern medical problems should be studied and innovation resolutions should be searched, which can help the internationalization and modernization of abdominal acupuncture.

    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.

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.

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

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.

    Intra-abdominal pressure is the pressure's state of balance within the abdominal cavity when a patient is at rest. This pressure may vary during mechanical ventilation or spontaneous breathing. The objective was to establish the intra-abdominal pressure as a surgery predictor in patients with acute abdominal pain. From April to December, 2013, it was carried out a nested case-control study on patients with acute abdominal pain in the emergency room of a second level hospital. Thirty-seven patients fit the inclusion criteria; they all underwent surgery with a previous measurement of the intra-abdominal pressure. Based on the results of the anatomopathological study, we divided the patients into two groups: those with evidence of acute abdominal inflammatory process (n=28) (case group), and patients without evidence of acute abdominal inflammatory process (n=9) (control group). In the case group, 100 % of patients shown high intra-abdominal pressure with a p=0.01 (OR=5 [95 % CI=2.578-9.699]. In the case group, the mean intra-abdominal pressure was 11.46, and in the control group 9.2 (p=0.183). Abdominal pain requiring surgical intervention is directly related to intra-abdominal pressure>5 mmHg.

    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 El análisis de los transientes de potencial de circuito abierto (PCA constituye una herramienta útil para la comprensión de la disolución de un metal en medio dado. Sin embargo, su utilidad está supeditada a un conocimiento previo del sistema metal/solución en estudio. La evolución del potencial de circuito abierto en el tiempo del cobalto inmerso en una solución de carbonato/bicarbonato fue analizada teniendo en cuenta el efecto del transporte de masa, mediante un electrodo de disco rotatorio y las reacciones que explican la disolución del metal en dicho medio. Se observó que el tiempo necesario para alcanzar el valor estacionario del PCA es función del transporte de masa y que el PCA evoluciona hacia valores más positivos a medida que se incrementa la rotación de electrodo. Se verificó que el proceso de corrosión del metal es inicialmente controlado por la reacción catódica de reducción de oxígeno; sin embargo, pasado un tiempo de exposición, el necesario para aparecer los primeros productos de corrosión, la disolución del metal pasa a ser controlada anódicamente por la formación de una película no pasiva de CoO sobre la superficie, la cual a su vez es igualmente controlada por la difusión del complejo Co(CO322- desde el metal hasta el seno de la solución.

En este ejercicio se trata de describir cómo los medios de comunicación promovieron la formación de esos consensos y se volvieron ellos mismos importantes vínculos para la interpretación y la producción de sentido. El tema del estudio está relacionado con la manera en que parte de Latinoamérica desarrolló algunos de los principales argumentos de la modernidad y la tendencia a reunir enunciados de proveniencia diversa en unos pocos soportes discursivos institucionalizados, por lo que se desarrolla aquí una especie de narrativa de convergencia. De esa manera, a pesar de la creciente división del trabajo físico e intelectual fomentado por el avance del capitalismo, en Latinoamérica la legitimación del formato social moderno y los discursos de conformación de las identidades regionales se dieron con el advenimiento de los medios de comunicación, redundando en una alternativa a los esquemas cognitivos logocéntricos.

This study describes how media underpinned the construction of consensus and became a very important nexus between interpretation and meaning production.

Despite the increasing of specialization in intellectual and physical work, in Latin America the legitimacy of social shape and even the discursive construction of regional identities were deeply conditioned by the spreading of media activities.

Sin embargo, se presentan grandes pérdidas económicas asociadas a enfermedades durante su cultivo, aunado a la intervención intensiva que generan las prácticas acuícolas que van degradando el medio ambiente. Esto es, primero, por la utilización del agua que recibe grandes cantidades de desechos, así como el alimento no consumido por los organismos que se sedimenta en el fondo marino, dañando al ambiente que es habitado no solo por los organismos cultivados sino también por otras especies. Segundo, porque se introducen antibióticos y sustancias químicas al ecosistema durante el desarrollo de la actividad. Por ello, fue necesario evaluar el efecto de un antibiótico y un biocida sobre las bacterias que habitan un sistema de cultivo, en relación al desarrollo de resistencia y la presencia de lesiones en los distintos órganos de camarón Litopenaeus vannamei. El empleo de los compuestos puede generar una huella ecológica, ya que se considera que un sistema de cultivo tiene una influencia en el medio ambiente diez mil veces superior a su superficie.

    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.

    Patients with extensive loss of the abdominal wall tissue have few options for restoring the abdominal cavity. Composite tissue allotransplantation has been used for limited abdominal wall reconstruction in the setting of visceral transplantation, yet replacement of the entire abdominal wall has not been described. The purpose of this study was to determine the maximal abdominal skin surface available through an external iliac/femoral cuff-based pedicle. Five human cadaveric abdominal walls were injected with methylene blue to analyze skin perfusion based on either the deep inferior epigastric artery (DIEA; n = 5) or a cuff of external iliac/femoral artery (n = 5) containing the deep circumflex iliac, deep inferior epigastric, and superficial inferior epigastric, and superficial circumflex iliac arteries. Abdominal wall flaps were taken full thickness from the costal margin to the midaxillary line and down to the pubic tubercle and proximal thigh. In all specimens, the deep inferior epigastric, deep circumflex iliac, superficial inferior epigastric, and superficial circumflex iliac arteries were found to originate within a 4-cm cuff of the external iliac/femoral artery. Abdominal wall flaps injected through a unilateral external iliac/femoral segment had a significantly greater degree of total flap perfusion than those injected through the DIEA alone (76.5% ± 4% vs 57.2% ± 5%; Student t test, P DIEA vessel alone.

    2015-01-01

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

    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.

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.

    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.

    Post traumatic anterior abdominal wall hernia can be ignored in emergency settings. We here report the case of a 32-year-old patient with a BMI of 30 kg/m 2 , suffering from anterior abdominal wall hernia as a result of a road accident. This lesion wasn't detected during clinical examination. Abdominal tomodensitometry showed a defect of 8 cm in the anterior abdominal wall. The patient underwent surgery during which a musculoaponeurotic defect of 12 cm was detected. The repair was carried out using interrupted suture. The postoperative course was marked by a secondarily infected skin necrosis. The evolution was satisfactory after directed cicatrization. At 3 months postoperatively the patient was doing well with a healed wound and a strong abdominal wall.

    • Aortic dissection occurs when the layers of the aorta separate as a result of extra luminal cavity of blood through an intimal tear. Dissection limited to the abdominal aorta is rare. Unfortunately, the appropriate management of dissecting aneurysm of abdominal aorta is not documented yet. A 43 years old man was admitted to Al-zahra hospital in Isfahan with sudden onset of periumbilical abdominal pain. CT scan confirmed infrarenal dissection of abdominal aorta. Performing laparotomy, aorta was repaired using bifurcate collagen-coated Dacron graft. Surgical intervention with synthetic graft is recommended in patients with dissecting aortic aneurysm of infrarenal segments where the extent of dissection is limited and accessible.

    Full Text Available A forma de avaliar e lidar com a hemorragia aguda digestiva baixa tem sido modificado com os recentes desenvolvimentos de novas técnicas e aparelhos. O nosso objetivo, por esse manuscrito, é demonstrar com simplicidade uma forma de condução dos pacientes com hemorragia digestiva baixa aguda, sobretudo para os sangramentos que parecem mais graves, principalmente quando nos faltam os recursos das avançadas tecnologias atuais. Doenças localizadas no intestino grosso respondem por ¼ dos casos de hemorragias digestivas que são motivos para admissão hospitalar e têm como principais agentes etiológicos os divertículos, na moléstia diverticular, e as alterações vasculares, nas angiodisplasias. Na grande maioria das vezes o sangramento que pode parecer abundante cessa espontaneamente. Os distúrbios circulatórios graves não são comuns e os sinais mais frequentes são a queda do valor da hemoglobina observada na metade dos pacientes, e algumas alterações hemodinâmicas como a variação pressórica postural que pode ser vista em até 30% dos casos; a síncope em 10% e alguma forma de colapso circulatório, em 9%. Contudo, a faixa etária em que ocorre, as condições da senilidade, as doenças eventualmente associadas e a falta de recursos materiais e humanos para lidar com esse tipo de problema são os motivos que mais causam preocupação. A abordagem clínica simples com uma história bem elaborada; o exame físico com atenção e objetividade, a inclusão do exame proctológico, a obrigatória disponibilidade de aparelho para a coloscopia e os conhecimentos básicos sobre o evento formam o conjunto necessário e, na maioria das vezes, suficiente para o correto desempenho profissional na elaboração dos cuidados que devem ser dados a esses pacientes.The evaluation and management of the acute lower digestive hemorrhage has been modified with the recent development of new techniques and devices.

    We report on our experience with routine abdominal ultrasonography in 120 children (aged 3-15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n...... = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. CONCLUSION: The diagnostic value of abdominal ultrasonography in unselected children with recurrent abdominal pain is low. However, the direct visualization...... of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain....

Elementos que pueden ser anexionados o circunscritos en el ejercicio del biopoder en la Modernidad. Al exponer la relación de estos elementos preguntamos por la existencia dada del organismo o del viviente en su medio, lo cual conlleva conocer la emergencia del concepto medio y, a su vez, saber cómo se dio su desbloqueo epistemológico en el tránsito de la mecánica a la biología y a la literatura, para después situarse en la arquitectura. Una vez conocida la historia del concepto medio se discute la idea general de que el viviente, en este caso el humano, al identificarlo como homo faber, transforma su medio de manera unidireccional, ante lo cual se opone la tesis de que el humano al transformar su medio, haciéndolo artificial, termina siendo afectado por esa artificialidad misma. Por esta afectación del hombre sobre su medio y viceversa, se plantea la importancia de recurrir a una teoría del medio puesta en relación con los dispositivos de seguridad y, en todo caso, con el biopoder

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

    Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

    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. 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. 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. 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.

    Full Text Available Sarah L Gans,1 Jaap Stoker,2 Marja A Boermeester11Department of Surgery, 2Department of Radiology, Academic Medical Center, University of Amsterdam, Amsterdam, The NetherlandsAbstract: Several studies have demonstrated that a diagnosis based solely on a patient’s medical history, physical examination, and laboratory tests is not reliable enough, despite the fact that these aspects are essential parts of the workup of a patient presenting with acute abdominal pain. Traditionally, imaging workup starts with abdominal radiography. However, numerous studies have demonstrated low sensitivity and accuracy for plain abdominal radiography in the evaluation of acute abdominal pain as well as various specific diseases such as perforated viscus, bowel obstruction, ingested foreign body, and ureteral stones. Computed tomography, and in particular computed tomography after negative ultrasonography, provides a better workup than plain abdominal radiography alone. The benefits of computed tomography lie in decision-making for management, planning of a surgical strategy, and possibly even avoidance of negative laparotomies. Based on abundant available evidence, major advances in diagnostic imaging, and changes in the management of certain diseases, we can conclude that there is no place for plain abdominal radiography in the workup of adult patients with acute abdominal pain presenting in the emergency department in current practice.Keywords: abdominal x-ray, acute abdomen, acute abdominal pain, emergency department, diagnostic imaging, abdominal radiography

Patients with abdominal wound dehiscence: 15 (8.5%). The global risk score of abdominal wound dehiscence group (mean: 4.97; IC 95%: 4.15-5.79) was better than the global risk score of No abdominal wound dehiscence group (mean: 3.41; IC 95%: 3.20-3.62). This difference is statistically significant (P<.001). The preoperative risk score of abdominal wound dehiscence group (mean: 3.27; IC 95%: 2.69-3.84) was better than the preoperative risk score of No abdominal wound dehiscence group (mean: 2.77; IC 95%: 2.64-2.89), also a statistically significant difference (P<.05). The global risk score (area under the ROC curve: 0.79) has better accuracy than the preoperative risk score (area under the ROC curve: 0.64). The risk model developed by van Ramshorst et al. to predict the abdominal wound dehiscence's risk in the preoperative phase has a limited usefulness. Additional refinements in the preoperative risk score are needed to improve its accuracy. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    The Program of Information, Education, and Services for Basic Family Health Care in Magdalena Medio and Bajo was designed to increase knowledge and use of contraception and to improve basic health practices and nutrition in the region, which includes municipios belonging to 9 different departments and a total population of 1,720,000. Poverty levels in the area are high. During the 1st year of the project, which was underway from February 1988-May 1991, home visits were made to inform each family about basic family health, to weigh and measure children under 5 not receiving health care elsewhere, and to refer families to the nearest health services. Talks were presented to small groups on family planning, intestinal parasites, sexually transmitted diseases, nutrition, vaccination, cancer prevention, malaria, acute diarrhea, and acute respiratory infection. Community workshops were presented in the 2nd year. Community distribution posts were created for contraceptive and other health product distribution. Information and communication materials from PROFAMILIA were used, and other materials were specially designed for the project by the Foundation for Development of Health Education in Colombia. PROFAMILIA's system of service statistics was used for quantitative evaluation of the information and education activities and sales of contraceptives, antiparasitics, and oral rehydration packets of each instructor. In the 3 years of the program, 89.086 cycles of pills, 398,772 condoms, 29,080 vaginal tablets, 209.791 antiparasitics, and 49,305 oral rehydration packets were sold. 9295 talks were presented to 143,227 residents of the region. 22,000 children were enrolled in the growth monitoring program, and almost 40,000 women were referred for prenatal care and cytology. The instructors gave 900 talks to distributors of contraceptives, antiparasitics, and oral rehydration packets. Surveys of women aged 15-49 residing in the municipios covered by the project were conducted

    Abdominal incisional hernia is a common complication after open abdominal operations. Laparoscopic procedures have obvious mini-invasive advantages for surgical treatment of abdominal incisional hernia, especially to cases with big hernia defect. Laparoscopic repair of incisional hernia has routine mode but the actual operations will be various according to the condition of every hernia. Key points of these operations include design of the position of trocars, closure of defects and fixation of meshes. The details of these issues and experiences of perioperative evaluation and treatment will be talked about in this article. PMID:27761446

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

El ecosistema del delta del Río Colorado, el cual en sus orígenes era caudaloso y ofrecía una gran variedad de alimentación, especialmente en su confluencia con el Río Gila, ha sufrido cambios drásticos, los cuales han afectado a la flora y fauna de esta región. Como consecuencia, sus habitantes, los indígenas Cucapá se vieron obligados a emigrar a tierras más bajas, debido a que el agua bajó tanto que ya no subían a las ricas tierras boscosas, sino solo hasta el desierto, y al igual que estas ricas regiones ellos se encuentran en grave peligro de desaparecer y además desprotegidos.

    A local Magnitude (ML) scale for Valle Medio del Magdalena (VMM) region was defined by using 514 high quality earthquakes located at VMM area and inversion of 2797 amplitude values of horizontal components of 17 stations seismic broad band stations, simulated in a Wood-Anderson seismograph. The derived local magnitude scale for VMM region was: ML =log(A) + 1.3744 ∗ log(r) + 0.0014776 ∗ r - 2.397 + S Where A is the zero-to-peak amplitude in nm in horizontal components, r is the hypocentral distance in km, and S is the station correction. Higher values of ML were obtained for VMM region compared with those obtained with the current formula used for ML determination, and with California formula. With this new scale ML values are adjusted to local conditions beneath VMM region leading to more realistic ML values. Moreover, with this new ML scale the seismicity caused by tectonic or fracking activity at VMM region can be monitored more accurately.

    Geological investigations were performed at Sierra del Medio (Chubut Province), a mountainous massif of about 25 km by 8 km of migmatic origin, which emerges from a depressed tectonic trench or graben called Pampa de Gastre. The most ancient rocks belong to biotitic and anphibolic schist that passed almost entirely to tonalitoid migmatites with a second process producing granitic rocks. Boreholes were drilled on the basis of conclusions from Landsat satellites imagery and aerial photographic sets, folowed by field work on geological, petrographic, geophysical and hydrogeological features at surface, structural interpretation supported by geostatistical computations. Two sets of boreholes were drilled to investigate subsurface rock behaviour al 300 m depth and 800 m depth respectively, beginning at peripheral places and ending at the central part or selected site. Basic purposes of boreholes were to define structural and petrographic features of the rock massif by a good comprehension of master joints and faulting distribution with its belts of alteration mylonitization or brecciation, mechanical properties of samples, chemical composition and varitions, petrographic facies and mineralogy. Boreholes provided data to investigate joints, faults and dikes as general discontinuities for hydraulic research like permeability or effective hydraulic conductivity, and their geostatistical modelling. Boreholes are also being prepared for geophysical logging from which logthermal ones have already been completed. (Author) [es

    Hereditary angioedema is an episodic swelling disorder with autosomal dominant inheritance characterized by sudden attacks of peripheral swelling. Patients also commonly have episodic swelling of the wall of hollow viscera, including the bowel. We present a 33-year-old previously healthy male with a complaint of acute-onset intense abdominal pain localized in the epigastrium. Pain irradiated to the right lower quadrant and was associated with five episodes of vomiting. Computed tomography showed thickening of the duodenal wall with liquid in the subphrenic space. Complementary laboratory tests showed low C4 complement levels (5.5 mg/dl) and 30% complement C1 inhibitor activity. Hereditary angioedema is caused by a deficiency (type I) or dysfunction (type II) in complement C1 inhibitor. Abdominal associated with angioedema may manifest as severe acute-onset abdominal pain or as moderately severe chronic recurrent abdominal pain. Two medications are currently FDA-approved for the treatment of these patients.

    Abdominal wall hernias are a common condition. However, they may develop acute complications and require surgical correction in most cases. Hence, the correct radiological examination is requisite for an accurate diagnosis. A multi-detector row CT (MDCT) provides an accurate identification of the anatomy of the abdominal wall, precise hernia type, and helps in the detection of early signs of complication. We report various imaging features of abdominal wall hernias via a MDCT.

    The use of computed tomography (CT) to screen for injuries in pediatric blunt abdominal trauma (BAT) is increasing, concurrent with increasing concern over long-term risk of radiation-associated malignancies. We proposed to determine features that could be identified in the early assessment of these patients, which can predict the likelihood of clinically important intra-abdominal injuries warranting imaging by CT. We further queried if these were discrepant from factors associated with the decision to obtain an abdominal CT. Data of patients admitted with BAT to one of two Level I pediatric trauma centers were reviewed retrospectively. Clinical, laboratory, radiographic, and epidemiologic data were collected. Logistic regression was used to determine associations between pre-CT findings and ultimate diagnoses of "notable" or "clinically important" intra-abdominal injuries. Similar analyses were performed to determine which findings were associated with actually receiving an abdominal CT scan. Of 571 patients, 37% had a notable intra-abdominal injury and 18% a clinically important intra-abdominal injury. After adjusting for all covariates, hematuria (gross or microscopic), elevated serum alanine aminotransferase, and documentation of clinically concerning abdominal findings upon examination remained significant predictors (odds ratio (OR), 3.5; 95% confidence interval [CI], 1.8-6.8; OR, 10.9; 95% CI, 2.5-47, respectively) of a clinically important injury. Undergoing a CT head and the presence of hematuria were significantly associated with obtaining a CT of the abdomen (OR, 3.4; 95% CI, 1.5-7.7; OR, 2.9; 95% CI, 1.1-7.3, respectively), while concerning abdominal findings and decreased Glasgow Coma Scale (GCS) score were not. Clinical variables may be used to predict intra-abdominal injuries after pediatric BAT that may warrant imaging with CT scanning. Combined with findings from similar studies, it may be possible to derive and validate a decision-making rule both

    Stab wounds (SW) to the abdomen traditionally require urgent exploration when associated with shock, evisceration, or peritonitis. Hemodynamically stable patients without evisceration may benefit from serial exams even with peritonitis. We compared patients taken directly to the operating room with abdominal SWs (ED-OR) to those admitted for serial exams (ADMIT). We retrospectively reviewed hemodynamically stable patients presenting with any abdominal SW between January 2000 and December 2012. Exclusions included evidence of evisceration, systolic blood pressure ≤110 mm Hg, or blood transfusion. NON-THER was defined as abdominal exploration without identification of intra-abdominal injury requiring repair. Of 142 patients included, 104 were ED-OR and 38 were ADMIT. When ED-OR was compared with ADMIT, abdominal Abbreviated Injury Score was higher (2.4 vs 2.1; P = 0.01) and hospital length of stay was longer (4.8 vs 3.3 days; P = 0.04). Incidence of NON-THER was higher in ED-OR cohort (71% vs 13%; P ≤ 0.001). In a regression model, ED-OR was a predictor of NON-THER (adjusted odds ratio 16.6; P patient from ED-OR expired after complications from NON-THER. There were no deaths in the ADMIT group. For those patients with abdominal SWs who present with systolic blood pressure ≥110 mm Hg, no blood product transfusion in the emergency department and lacking evisceration, admission for serial abdominal exams may be preferred regardless of abdominal exam.

    Full Text Available Background Recurrent abdominal pain is common among adolescents. School absenteeism and lower quality of life are associated with severity of symptoms. Lansoprazole has been used to treat recurrent abdominal pain. Objective To investigate the effectiveness of lansoprazole as a treatment for recurrent abdominal pain in adolescents. Methods We conducted a randomized, double-blind, controlled trial from August 2009 to October 2009. Adolescents suffering recurrent abdominal pain were eligible for the study. Simple randomization was done to divide subjects into two groups. Groups received 30 mg of lansoprazole or placebo, once a day for 14 days. Before treatment, we performed laboratory and physical examinations. Pain frequency was measured in number of abdominal pain episodes per month. Duration was measured in minutes and pain intensity was measured by a pain rating scale. Drug efficacy was measured before, during and after intervention. Data was analyzed using Mann-Whitney U-test and t-test. Results One hundred sixteen recurrent abdominal pain patients were randomized into two groups of 58 patients. There were no statistically significant differences in pain frequency before and after treatment for either the lansoprazole group or the placebo group (P=0.083, 95%CI, -0.033 to 0.021 and P=0.096, 95%CI -0.376 to 0.031, respectively. In addition, there were no significant differences in frequency, duration, and degree of abdominal pain at baseline and after 1, 2 and 3 months of treatment between the two groups. Conclusion Lansoprazole was not more effective than the placebo for treatment of recurrent abdominal pain among adolescents.

    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.

    The anterior abdominal wall has received little attention in the ultrasonic evaluation. However recently the improved resolution of ultrasound scanning devices has made possible routine examination of the anterior abdominal wall. The authors evaluated ultrasonographic findings of anterior abdominal wall lesions in 27 cases for 1 year(from July '82 to Aug. '83), which were finally diagnosed pathologically and clinically. The results were as follows: 1. Well defined peritoneal line and layers of the anterior abdominal wall made it possible to localize the lesions accurately from adjacent structures. 2. Abscess and hematoma were lower in echogenecity than adjacent tissues, such as muscle layer or subcutaneous fat space and were well delineated from normal structures. 3. In hernia, easy differentiation was made due to oval shape, poor or decreased echo pattern and protrustion from skin layer. Conclusively, in the doubtful cases of palpable mass in the abdominal wall, postoperative complications of sequele, such as accurately but also the guide of treatment. Ultrasonography of anterior abdominal wall is useful to demonstrate the exact location, extent of the lesions and to decrease the frequency of useless laparatomy

    Full Text Available Los medios audiovisuales y, en especial, los documentales vienen jugando un papel fundamental en la construcción y reconstrucción colectiva de las realidades en comunidades o en organizaciones sociales. En ellos se incluyen una multiplicidad de prácticas: cine, actuación, fotografías, videos y otros testimonios y modalidades de participación. La reflexión sobre los materiales audiovisuales y su posible utilización en los procesos de intervención social ha cobrado importancia a partir del progresivo giro de las ciencias sociales desde la academia a la incorporación de prácticas de transferencia de resultados de investigación social a los procesos de toma de decisiones por parte de funcionarios, pero sobre todo de organizaciones de la sociedad civil enroladas en visiones críticas y aspiraciones de cambio social. Una de las disciplinas que se ha desarrollado para el estudio de este campo es la sociología visual. El trabajo revisa los principales aspectos de la incorporación de estas prácticas en la investigación social, especialmente en cuanto al uso del video participativo como recurso para promover el involucramiento de las comunidades en el análisis y las posibilidades de transformación de sus realidades. Se pasa revista también a las particularidades del consentimiento informado en relación con la metodología de investigación que incluye métodos audiovisuales.

  14. Ruling out intra-abdominal injuries in blunt trauma patients using clinical criteria and abdominal ultrasound

    Flávia Helena Barbosa Moura

    Full Text Available ABSTRACT Objective: to identify victims of blunt abdominal trauma in which intra-abdominal injuries can be excluded by clinical criteria and by complete abdominal ultrasonography. Methods: retrospective analysis of victims of blunt trauma in which the following clinical variables were analyzed: hemodynamic stability, normal neurologic exam at admission, normal physical exam of the chest at admission, normal abdomen and pelvis physical exam at admission and absence of distracting lesions (Abbreviated Injury Scale >2 at skull, thorax and/or extremities. The ultrasound results were then studied in the group of patients with all clinical variables evaluated. Results: we studied 5536 victims of blunt trauma. Intra-abdominal lesions with AIS>1 were identified in 144 (2.6%; in patients with hemodynamic stability they were present in 86 (2%; in those with hemodynamic stability and normal neurological exam at admission in 50 (1.8%; in patients with hemodynamic stability and normal neurological and chest physical exam at admission, in 39 (1.5%; in those with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, in 12 (0.5%; in patients with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, and absence of distracting lesions, only two (0.1% had intra-abdominal lesions. Among those with all clinical variables, 693 had normal total abdominal ultrasound, and, within this group, there were no identified intra-abdominal lesions. Conclusion: when all clinical criteria and total abdominal ultrasound are associated, it is possible to identify a group of victims of blunt trauma with low chance of significant intra-abdominal lesions.

    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.

    Full Text Available Una niña indigena de 4 años de edad, procedente de Carurú, Vaupés, un municipio semiselvático de 2.000 habitantes, presentó hematoquecia repetida con sincope y muerte 4 días después, a pesar de recibir transfusiones sanguíneas. El estudio postmortem descubrió dos masas de 3-4 cm de diámetro en el ileon distal que, al microscopio, correspondieron a inflamación severa de toda la pared intestinal, rica en eosinofilos y en granulomas con células gigantes que circunscribian y fagocitaban huevos y larvas de Angiostrongylus costaricensis, helminto situado también dentro de las arterias de la submucosa, vasos que presentaban engrosamiento de la intima y focos con inflamación granulomatosa con eosinófilos. La niña no presentó leucocitosis ni eosinofilia. Este es el segundo caso de angiostrongilosis de esta región. El primero fue el de una mujer indigena de 34 años también con hematoquecia anemizante. La angiostrongilosis abdominal se diagnosticó por primera vez en Colombia en 1979, en un niño de 5 años, de Dagua, Valle. La niña aquí presentada es el sexto paciente con esta entidad en Colombia. La hematoquecia como manifestación predominante de la angiostrongilosis es extraordinaria para una enfermedad parasitaria; se ha registrado solamente en tres ocasiones anteriores. La abundancia de cristales de Charcot-Leyden, que se tiñen muy bien con la coloración de Ziehl-Neelsen o de Fite-Faraco, en los infiltrados de la pared intestinal. sugiere que su búsqueda en las heces puede ser una ayuda en el diagnóstico de casos sospechosos. pues, los huevos y las larvas no se eliminan en las heces y el diagnóstico definitivo de la angiostrongilosis es histopatológico. Revisamos las caracteristicas clinicas, parasitológicas e histopatológicas de esta parasitosis que será más prevalente en Colombia a medida que los médicos. especialmente los patólogos, la conozcan mejor.

    2017-02-01

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

    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.

    Full Text Available Background. Abdominal compartment syndrome (ACS is a rapid increase in intra-abdominal pressure associated with multi-organs dysfunction. It is caused mostly by abdominal bleeding und massive volume compensation. Case report. We reported a 76-year-old patient admitted to the hospital with aortic abdominal aneurysm, 13.7 cm in diameter, ruptured in vena cava, which caused intraabdominal hypertension, the liver and kidney dysfunction, as well as circulation, respiration and metabolic disorders. Intraabdominal pressure was measured by bladder manometry. Central venous pressure and systemic arterial pressure were monitored continuously. Clinical signs were thrill and typical abdominal bruit. Aorto-caval fistula was diagnosed by the use of contrast computerized tomography. Caval endoaneurysmatic suture and aortobiiliac bypass with 18 × 9 mm Dacron prothesis were performed. Haemodynamic changes were mostly corrected during the surgery. The complete correction of haemodynamics, liver, kidney, respiration and metabolic changes was established in the next few weeks. Conclusion. The ACS was caused by rupture of abdominal aortic aneurysm in vena cava followed by edema of the abdominal organs, retroperitoneum, abdominal wall and ascites. Caval endoaneurysmatic suture and aortobiiliac bypass with 18 × 9 mm Dacron prothesis solved aortocaval fistula as well as all the organs and metabolic dysfunctions caused by ACS.

    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)

    sequential measurement of intra-abdominal pressure is of paramount importance for an early detection and appropriate therapeutic management of intra-abdominal hypertension and abdominal compartment syndrome. to validate a device and technique developed to measure intra-abdominal pressure (an innovation of the Foley urinary catheter named intra-abdominal pressure catheter). three different sets of measurements where done to test the intra-abdominal pressure catheter device: I. 50 measurements were done with the intra-abdominal pressure catheter device and compared against those measurements done using a manometer graded in cm H(2)O; II. Direct measurement of intra-abdominal pressure in five patients during elective laparoscopy vs the intraabdominal pressure catheter device; and III. Measurement of intra-abdominal pressure by the Kron method (Gold standard) vs intra-abdominal pressure catheter device in three patents with intra-abdominal hypertension/abdominal compartment syndrome. Measurements where compared with Pearson correlation test and Bland Altman statistics. I.Intra-abdominal pressure catheter vs graded manometer: r = 0.99, with a mean pressure difference of 0.27 ± 0.23 mmHg, CI (0.039 to 0.092 mmHg). II. Direct measurement of intra-abdominal pressure during laparoscopy vs intra-abdominal pressure catheter device: r = 0.93, with a mean pressure difference of 0.18 ± 0.84 mmHg, CI (-1.46 to 1.83 mmHg) and III. Measurement of intra-abdominal pressure by the Kron Method vs intra-abdominal pressure catheter device: r = 0.81, with a mean pressure difference of -0.41 ± 0.87, CI (-2.12 mmHg to 1.30 mmHg). the intra-abdominal pressure catheter device is a safe and reliable instrument for measuring intra-abdominal pressure.

    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.

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.

    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 Abdominal pain is a common occurrence in the elderly patients and poses a difficult challenge for the emer-gency physician. Previous studies demonstrated that among the elderly patients presenting to the emergency department with abdominal pain, at least 50% were hospitalized and 30–40% eventually had surgery for the underlying condition. Reasons for the difficult diagnosis of acute abdomen in the elderly are multifactorial, and hence the diagnostic accuracy is lower and the mortality far higher in them than in the younger patients. High suspicion, widely differential diagnosis, and more aggressive use of imaging modalities are critical for these patients. In the geriatric population, biliary tract disease accounts for nearly 25% of cases of acute abdominal pain, followed by nonspecific pain, malignancy, bowel obstruction, complicated peptic ulcer disease, and incarcer-ated hernia. Acute appendicitis, pancreatitis, and diverticulitis are uncommon but important causes of acute abdomen in the elderly. Abdominal vascular diseases, including abdominal aortic aneurysm and mesenteric ischemia, are a rare but lethal condition in acute abdomen. Management of the elderly patients with acute abdomen should focus on keeping the vital signs, adequate hydration, and early administration of analgesics and antibiotics. Consultations with radiologists and surgeons are crucial in the management of difficult cases.

    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.

    Full Text Available The aim of this investigation is to determinate the effects of parameters and additives on the kinetics of dissolution of chalcopyrite on moderated conditions by means of dissolutions test with chalcopyrite concentrate and pure chalcopyrite in shake flasks and instrumented stirred reactors. A study of the dissolution of chalcopyrite in chloride solutions has demonstrated that the rate of dissolution of chalcopyrite is strongly dependent on the potential of the solution within a range of 540 to 630 mV (versus SHE. Leaching at pH around 2.5 results in increased rates of copper dissolution suggesting the possibility to keep the solution potential within the range. Both pyrite and silver ions enhance the dissolution of chalcopyrite and this effect increases when both species are present. The MnO2 has a negative effect on the dissolution increasing the solution potential to values where the rate decreases considerably.El objetivo de esta investigación es determinar el efecto de parámetros y aditivos (MnO2 - iones de plata - pirita en la cinética de disolución de la calcopirita mediante pruebas de disolución con concentrado de calcopirita y calcopirita natural en matraces y reactores agitados mecánicamente bajo condiciones moderadas. La disolución de la calcopirita en medios clorurados es dependiente del potencial de la solución, obteniéndose valores de velocidad aceptables dentro de los 540 y 630 mV (SHE. El pH alrededor de los 2,5 permite mantener los potenciales de solución en valores donde la calcopirita lixivia a velocidades aceptables debido a que ocurre la precipitación de hierro. Tanto la pirita como los iones de plata catalizan la disolución y el efecto es mayor con ambas especies presentes. El MnO2 posee un efecto negativo en la disolución debido a que aumenta el potencial de la solución a valores donde la velocidad disminuye considerablemente.

    Full Text Available De todas as mortes por causas externas por trauma, metade poderia ser evitada, e um terço delas é dito potencialmente evitável. Objetiva-se determinar as características comuns referentes ao paciente com traumatismo abdominal. Realizou-se um estudo de 57 casos de pacientes com traumatismo abdominal atendidos no Hospital Universitário Regional de Maringá, no período de janeiro a dezembro de 2006. Constatou-se que a maioria das vítimas é do sexo masculino; a faixa etária mais acometida é a terceira década de vida; o trauma abdominal aberto mostrou-se discretamente mais frequente, sendo o ferimento por arma branca mais comum; a maioria das contusões abdominais se deveu a acidentes de trânsito; a realização de intervenção cirúrgica supera o tratamento conservador nos traumas abdominais abertos; nos traumas contusos, o baço e os rins foram os órgãos mais acometidos, enquanto nos ferimentos abertos a víscera mais acometida foi o intestino delgado; a evolução para óbito predominou nos traumas abdominais abertos. Em virtude da prevalência, gravidade e importância do tema, sugere-se que mais estudos sejam realizados para que, assim, seja possível estabelecer condutas cada vez mais apropriadas à realidade do Sistema Único de Saúde.Of all the deaths due to external cause trauma, half could be avoided, and a third are potentially preventable.

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

    Full Text Available No período de janeiro de 1993 a janeiro de 2003, foram realizados 195 procedimentos cirúrgicos de abdômen agudo em eqüinos, no Serviço de Cirurgia de Grandes Animais do Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo. Dentre eles, foram diagnosticados 30 casos de enterolitíase e sete casos de corpo estranho, localizados em intestino grosso. Das 37 laparotomias, 35 foram realizadas em decúbito dorsal com acesso pela linha média e duas em estação com acesso pelo flanco. Os animais apresentaram idade variando de um a dezoito anos com média de oito anos, sendo 25 machos e 13 fêmeas. As formações e corpos estranhos apresentaram a seguinte localização: 13 (35,14% em cólon maior, 19 (51,35% em cólon menor, 03 (8,10% em cólon transverso e 02 (5,41% em cólon transverso e menor. Em relação à evolução, 23 (62,16% receberam alta e 14 (37,84% evoluíram para óbito (6 ou foram submetidos à eutanásia (8. Seis procedimentos de eutanásia foram realizados no período trans-operatório e dois no período pós-operatório. Dentre os animais que apresentaram evolução satisfatória, destacam-se um caso em que foram retirados sete enterólitos e outro em que a ponta de um prego que era o núcleo do enterólito se mantinha proeminente e em contato com a mucosa intestinal. Comparativamente às demais afecções do intestino grosso dos eqüinos e pela análise dos resultados obtidos neste estudo, conclui-se que os processos obstrutivos causados por enterólitos ou corpos estranhos apresentam prognóstico favorável.

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

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

    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.)

    Necrotizing fasciitis (NF) is a rare infection (0,2 to 0,4/100,000 adults) of the dermis and hypodermis extending along muscular fascia1. The absence of pathognomonic symptoms makes its diagnosis difficult. Rapidly progressive, it is a life-threatening emergency whose prognosis is letal in 30 % of cases. Treatment of necrotizing fasciitis is mixed and involves aggressive surgical debridement and medical treatment with antibiotics and supportive agents. This article is presenting the case of a young woman who developed abdominal necrotizing fasciitis following a caesarean section. In forty-eight hours, the patient developed septic shock with an extensive and rapid destruction of her abdominal wall. After hysterectomy and multiple surgical debridements, evolution was favorable. After one month, a reconstruction of the abdominal wall could be performed.

  7. Abdominal respiratory motor pattern in the rat.

    2010-01-01

    In this brief review, I focused on the abdominal expiratory motor pattern in the rat. In the vagotomized adult rat, hypercapnic acidosis evoked two patterns of the abdominal expiratory activity; one with low amplitude expiratory discharge (E-all activity) that persisted throughout the expiratory phase, and another with late expiratory and high amplitude bursts (E2 activity) superimposed on the E-all activity. The E-all activity appeared from milder acidosis than the E2 activity. In the anesthetized, vagotomized or vagus-intact neonatal rats, abdominal muscles often showed not only E2 activity but also a smaller additional burst occurred just after the termination of diaphragmatic inspiratory activity (E1 activity). Since this E1 activity is rarely observed in the adult rat, the abdominal respiratory motor pattern likely changes during postnatal development. Under light anesthesia, vagal afferent feedback shortened the respiratory cycle period due to shortening of the expiratory duration. Further decrement in depth of anesthesia changed the biphasic E2+E1 abdominal motor activity pattern to E-all activity pattern in the vagus-intact neonatal rat. Since this E-all activity was typically observed with short cycle period in the vagus-intact neonatal rat, relation with the E-all activity in the vagotomized adult rat remained unknown. The vagal feedback should have roles not only in setting the cycle period short but also shaping the expiratory motor pattern in the neonatal rat. Although abdominal muscles in the in vitro preparation from neonatal rat also showed biphasic E2+E1 activity, E2 activity was shorter and/or smaller than the E1 activity.

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

    The clinical usefulness of computed tomography (CT) for the diagnosis of abdominal abscess was evaluated in 62 cases with suspicious abdominal abscesses. Sensitivity and specificity of CT were 96% and 89%, respectively. When no evidence of abscess cavity was seen on CT, our results suggested that the presence of surgically treatable abscesses could practically be denied. On the other hand, even if abscesses were diagnosed on CT, all of them were not necessary to be treated surgically. Other possibilities such as hematoma and necrotic tumor should also be considered.

    Intraabdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are rare conditions with high mortality. IAH is an intraabdominal pressure (IAP) above 12 mmHg and ACS an IAP above 20 mmHg with evidence of organ dysfunction. IAP is measured indirectly via the bladder or stomach. Various...... medical and surgical conditions increase the intraabdominal volume. When the content exceeds the compliance of the abdominal wall, the IAP rises. Increased IAP affects the functioning of the brain, lungs, circulation, kidneys, and bowel. The treatment of ACS is a reduction of IAP Udgivelsesdato: 2008/2/11...

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

    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 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)

    An abdominal aortic aneurysm was detected in 77 patients among 16 488 abdominal ultrasonographies (US) performed in 1978-1983. In 62 cases the US finding was confirmed by operation, autopsy or other imaging method, and the US finding proved true in 60 cases. The length and diameter were accurately estimated and accompanying thrombosis reliably visualised. An error rate of 24% was observed in assessing the relation of the aneurysm to the renal arteries. US is recommended as the primary imaging mode in suspected abdominal aortic aneurysm. Screening of the abdominal aorta is recommended in elderly patients with abdominal pain and/or referred for abdominal US. (orig.) [de

    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 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.

    Gastrointestinal tract and abdominal lymph nodes are common sites for development of lymphosarcomas in children (36-53% of all lymphomas). Lymphosarcoma is a malignant tumor developed from the lymphoid tissue and characterized with broad spectrum of clinical manifestations, inhomogeneous course of the disease and prognosis. 25 (24,0% of all abdominal lymphosarcomas) patients with intestinal lymphosarcoma admitted to the childhood tumors department of the National Cancer Center of Georgia from 1980 to 2006. One of the most informative diagnostic methods for this disease is X-ray examination. Ultrasound and CT are leading investigating methods giving us possibility to determine topography of the tumour as well as to evaluate efficiency of the specific treatment and carry out a dynamic control of the patients after the complete remission. In all patients with intestinal lymphosarcomas surgical treatment without any preoperative specific therapy (chemotherapy, radiotherapy) has been carried out. Analysis of the specific treatment results obtained has shown that intestinal lymphosarcoma is the disease with worse prognosis in comparison with abdominal lymph nodes lymphosarcoma. It has been ascertained that in 88,0% of abdominal lymph node damages complete cure can be achieved using surgery and rational program of ACOP chemotherapy.

    Rehabilitative ultrasound imaging (RUSI) of the abdominal muscles is increasingly being used in the management of conditions involving musculoskeletal dysfunctions associated with the abdominal muscles, including certain types of low back and pelvic pain. This commentary provides an overview of current concepts and evidence related to RUSI of the abdominal musculature, including issues addressing the potential role of ultrasound imaging in the assessment and training of these muscles. Both quantitative and qualitative aspects associated with clinical and research applications are considered, as are the possible limitations related to the interpretation of measurements made with RUSI. Research to date has utilized a range of methodological approaches, including different transducer placements and imaging techniques. The pros and cons of the various methods are discussed, and guidelines for future investigations are presented. Potential implications and opportunities for clinical use of RUSI to enhance evidence-based practice are outlined, as are suggestions for future research to further clarify the possible role of RUSI in the evaluation and treatment of abdominal muscular morphology and function.

    1999-01-01

    Purpose: The aims of the study were: (1) to assess the efficacy of different imaging methods for use prior to treatment; (2) to compare the surgico-histopathologically-based International Neuroblastoma Staging System (INSS) staging with the imaging results; and (3) to suggest a localisation scheme for abdominal neuroblastoma. Material and Methods: Thirty-one children with an abdominal neuroblastoma (median age 2 years), underwent abdominal US, CT of chest and abdomen, MR imaging of abdomen and spine, chest radiography, skeletal survey, radionuclide bone scintigraphy, MIBG scintigraphy, and bone marrow biopsy. Results: In the evaluation of local disease, CT and MR were superior to US. There was no significant difference between CT and MR in assessment of the location or size of the tumour. Evaluation of invasive growth and lymphadenopathy was uncertain irrespective of imaging modality. Intraspinal extension was more distinctly demonstrated with MR. Tissue characterization with CT and MR did not contribute in the assessment of the tumours. Contrast enhancement at CT and MR examinations both improved demarcation between tumour and kidney, and was a necessity for evaluation of vessel encasement with CT. The local disease was best assessed by either CT or MR, while metastatic disease was best revealed by CT, MR, scintigraphy or bone marrow biopsy. Conclusion: Imaging may be a valuable basis for clinical assessment and pretreatment staging of abdominal neuroblastoma. (orig.)

  3. Physical activity and abdominal obesity in youth.

    Science.gov (United States)

    Kim, YoonMyung; Lee, SoJung

    2009-08-01

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

    2011-01-01

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

  10. Clinical application of PET in abdominal cancers

    2002-01-01

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

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

    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.

  17. Intra-abdominal pressure and abdominal wall muscular function: Spinal unloading mechanism.

    Science.gov (United States)

    Stokes, Ian A F; Gardner-Morse, Mack G; Henry, Sharon M

    2010-11-01

    The roles of antagonistic activation of abdominal muscles and of intra-abdominal pressurization remain enigmatic, but are thought to be associated with both spinal unloading and spinal stabilization in activities such as lifting. Biomechanical analyses are needed to understand the function of intra-abdominal pressurization because of the anatomical and physiological complexity, but prior analyses have been over-simplified. To test whether increased intra-abdominal pressure was associated with reduced spinal compression forces for efforts that generated moments about each of the principal axis directions, a previously published biomechanical model of the spine and its musculature was modified by the addition of anatomically realistic three-layers of curved abdominal musculature connected by fascia to the spine. Published values of muscle cross-sectional areas and the active and passive stiffness properties were assigned. The muscle activations were calculated assuming minimized muscle stress and stretch for the model loaded with flexion, extension, lateral bending and axial rotation moments of up to 60 Nm, along with intra-abdominal pressurization of 5 or 10 kPa (37.5 or 75 mm Hg) and partial bodyweight (340 N). The analysis predicted a reduction in spinal compressive force with increase in intra-abdominal pressurization from 5 to 10 kPa. This reduction at 60 Nm external effort was 21% for extension effort, 18% for flexion effort, 29% for lateral bending and 31% for axial rotation. This analysis predicts that intra-abdominal pressure produces spinal unloading, and shows likely muscle activation patterns that achieve this. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Severe acute pancreatitis may be complicated by intra-abdominal hypertension (IAH), abdominal compartment syndrome (ACS), and intestinal ischemia. The aim of this retrospective study is to describe the incidence, treatment, and outcome of patients with severe acute pancreatitis and ACS, in particular the occurrence of intestinal ischemia. The medical records of all patients admitted with severe acute pancreatitis admitted to the ICU of a tertiary referral center were reviewed. The criteria proposed by the World Society of the Abdominal Compartment Syndrome (WSACS) were used to determine whether patients had IAH or ACS. Fifty-nine patients with severe acute pancreatitis were identified. Intra-abdominal pressure (IAP) measurements were performed in 29 patients (49.2 %). IAH was present in all patients (29/29). ACS developed in 13/29 (44.8 %) patients. Ten patients with ACS underwent decompressive laparotomy. A large proportion of patients with ACS had intra-abdominal ischemia upon laparotomy: 8/13 (61.5 %). Mortality was high in both the ACS group and the IAH group. This study confirms that ACS is common in severe acute pancreatitis. Intra-abdominal ischemia occurs in a large proportion of patients with ACS. Swift surgical intervention may be indicated when conservative measures fail in patients with ACS. National and international guidelines need to be updated so that routine IAP measurements become standard of care for patients with severe acute pancreatitis in the ICU.

    Full Text Available En Chile Pinochet es el ícono noticioso más importante de los 30 años últimos, fue la principal figura mediática durante los 17 años de régimen autoritario y en los 14 años de democracia. Los medios de comunicación sobrevivieron en el régimen militar por su adscripción al gobierno y al tirano, convirtiéndose en voceros no oficiales. Para los medios de comunicación internacionales el "dictador" para la prensa chilena el "general en retiro". Los crímenes de lesa humanidad y los atracos a los dineros del Estado y la corrupción en su mandato han hecho que su nombre persista en los medios.

    Full Text Available Durante la actual epidemia de cólera en nuestro pais, decidimos investigar la viabilidad del Vibrio cholera O1 en el medio de transporte Cary-Blair, el cual fue seleccionado como el medio para el envío de las muestras de materia fecal, siguiendo las recomendaciones de la OMS. La viabilidad fue determinada en 53 muestras las cuales se mantuvieron a temperatura ambiente (23% + 2, durante seis semanas, realizando subcultivos semanales. La recuperación de V. cholerae O1 fue del 94% la primera semana y del 89%, 87%, 83% 81% y 72% las semanas siguientes. La recuperación fue también directamente dependiente de la calidad de la muestra. Nuestros resultados nos permiten concluir que el medio de Cary-Blair es ideal para el envío de este tipo de muestras al laboratorio.
