    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 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.

    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.

    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.

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.

    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.

    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.

  12. Abdominal trauma

    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

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

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

  18. 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

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

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

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.

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

    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.

  6. Chronic Abdominal Wall Pain.

    Science.gov (United States)

    Koop, Herbert; Koprdova, Simona; Schürmann, Christine

    2016-01-29

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

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

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

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.

    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.

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

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

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

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

    Full Text Available Foram realizados dois experimentos (experimento 1 - alimentação convencional e experimento 2 - alimentação das matrizes, a partir de 109 dias de gestação, na lactação e dos leitões lactentes com ração sem farelo de soja, com o objetivo de avaliar os efeitos de fontes proteicas (farelo de soja - FS, soja semi-integral extrusada - SSIE e produtos lácteos - PL sobre a morfologia intestinal de leitões abatidos aos 0,5 e 15 dias após a desmama. Foram utilizados 27 leitões, desmamados aos 25 dias de idade, sendo que em cada idade, nove leitões foram abatidos. Utilizou-se o delineamento em blocos ao acaso, em esquema fatorial 3 x 3 (três dietas x três idades de abate. Os resultados demonstraram que os animais recebendo FS apresentaram menores alturas das vilosidades e relação vilosidade:cripta, quando comparados àqueles que receberam SSIE ou PL, não havendo, entretanto, diferenças entre estes. A altura da vilosidade e a relação vilosidade:cripta não foram afetadas pela alimentação diferenciada das matrizes e dos leitões antes da desmama. A profundidade das criptas não foi afetada pelas dietas ou idades de abate, dentro de cada experimento, em nenhum dos segmentos estudados, sendo, no entanto, menor no duodeno e maior no jejuno e íleo dos animais do exp. 2, quando comparados àqueles do exp. 1. Concluiu-se que o FS afetou negativamente a altura das vilosidades e a relação vilosidade:cripta após a desmama; que a morfologia intestinal foi mais afetada aos cinco dias, mostrando sinais de recuperação aos 15 dias após a desmama e que a alimentação das matrizes não afetou a morfologia dos segmentos do intestino delgado.

    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.

    Grover, Madhusudan; Drossman, Douglas A

    2010-10-01

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

  13. Adult abdominal hernias.

    LENUS (Irish Health Repository)

    Murphy, Kevin P

    2014-06-01

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

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

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.

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

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

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

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

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

    Full Text Available La presente colaboración pone en la mesa del debate los objetivos de un banco de desarrollo, en la tradición económica-desarrollista, donde la satisfacción del desarrollo de los recursos naturales intentan mejorar no las condiciones de la población sino lograr las ventajas comparativas y el valor agregado que da la inserción al mercado mundial, frente a lo que debería ser un banco de desarrollo que invierta esa ecuación. La explotación de los recursos de una parte importante de la Amazonia está ligada a fomentar toda una serie de obras de infraestructura que harían un gran daño no sólo ecológico a la región sino a generaciones futuras. El autor discute la difícil problemática entre un banco de desarrollo que busca el equilibrio con el medio ambiente y un banco de desarrollo ligado a los intereses tanto del Estado como de las oligarquías exportadoras.

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

    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 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.

    2015-09-02

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

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

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

    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 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.

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

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

    The goal of this study was to identify patients who need longer care in the ICU (more than 48 hours) following abdominal aortic aneurysm (AAA) surgery and to evaluate the influence of perioperative complications on short- and long-term survival and quality of life. AAA surgery was performed in 553...... patients, 51 (9%) of whom died within the first 48 hours. Of the 502 patients who survived for more than 48 hours, 109 required ICU therapy for more than 48 hours, whereas 393 patients were in the ICU for less than 48 hours. The incidence of preoperative risk factors was similar for the two groups...... combined failed to permit identification of patients in whom the perioperative survival rate was 0%. Even 20% of patients with multiorgan failure survived for 6 months. Of those patients who needed ICU therapy for more than 48 hours, 41 (38%) were alive at the end of 1988.

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

    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.

    Full Text Available Objetivos. Caracterizar bacterias ácido lácticas probióticas aisladas del intestino grueso de cerdos adultos como posible alternativa al uso de antibióticos. 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.

    2004-01-01

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

    1989-08-01

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

  4. Economics of abdominal wall reconstruction.

    2013-10-01

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

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

    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

    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.

    2017-01-01

    Incisional hernia is a common long-term complication to abdominal surgery, occurring in more than 20% of all patients. Some of these hernias become giant and affect patients in several ways.

    Abdominal actinomycosis is a chronic, progressive, suppurative disease with a favorable response to intravenous treatment with penicillin. In many instances, however, its clinical and radiological findings may overlap with those of other inflammatory and neoplastic conditions, and the familiarity with the various radiological features can thus avoid diagnostic delays. The purpose of this paper is to describe and discuss the CT findings of abdominal actinomycosis

  16. Blunt abdominal trauma in children.

    Science.gov (United States)

    Schonfeld, Deborah; Lee, Lois K

    2012-06-01

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

    Full Text Available Los medios rurales en los países desarrollados han experimentado notables cambios en las funciones que desempeñan desde mediados de la década de los cincuenta del siglo veinte. Frente a unos ámbitos donde dominaban las actividades y modos de vida rurales, en las últimas décadas se observa la progresiva aparición de nuevos usos y actividades vinculados a su terciarización. La homogeneización de las pautas de comportamiento y de los modos de vida hace difícil disociar la sociedad urbana de la rural. Este artículo reflexiona sobre los diferentes procesos (éxodo rural, políticas de desarrollo rural, medios de comunicación, etc. que han intervenido en estas transformaciones y han favorecido los procesos de homogeneización de los medios rurales, sin embargo, es necesario insistir que uno de los rasgos de numerosos medios rurales es su diversidad. Esta heterogeneidad condiciona, no solo su evolución, sino también su grado de adaptación a las nuevas funciones que se les asignan. Este artículo pretende realizar una reflexión acerca de las posibles disfuncionalidades que la aplicación de políticas homogéneas está generando en ámbitos contrastados.

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

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

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

    Full Text Available 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.

    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

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

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

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

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

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

  6. Torsion of abdominal appendages presenting with acute abdominal pain

    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)

    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.

    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.

Es la mejor manera de denunciar, advertir, sancionar e incluso develar lo que hace o deja de hacer el poder político. El humor político está considerado como contrapoder. El periodismo que usa el humor es eficaz, tanto en el mensaje como en su efecto, pues describe las situaciones y recurre a comparaciones y símiles....

    @@ Case History Mr. Li, a university student aged 23 years, paid his first visit on July 16, 2001, with the chief complaint of abdominal pain for one day. The patient stated that one day before when it happened to be the weekend, he got abdominal pain after supper, which went worse gradually and caused him to roll all over in bed. The pain was slightly alleviated half an hour later after he had taken some pain killers. Upon inquiry, the patient said that because of their newly graduation from the university, he and his classmates were so excited that they went to have a sumptuous lunch with alcoholic drinks. And in the evening he ate again a delicious supper cooked for him by his mother, after which he continued to have some fruit and dessert.

    The CT-examinations of 131 patients were analyzed after abdominal surgery. After nephrectomy, splenectomy, partial hepatectomy and pancreatectomy a displacement of the neighbouring intraabdominal and retroperitoneal organs was seen. Scar-tissue was observed containing fat, which faciltated the differential diagnosis to tumor recurrency. The changes of the roentgenmorphology were not so obvious after gastrointestinal surgery. After vascular surgery the permeability of an anastomosis or an operated artery could be demonstrated by bolus injection. (orig.).

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

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

  3. Appendicitis following blunt abdominal trauma.

    Science.gov (United States)

    Cobb, Travis

    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.

La perspectiva se construyó a partir de la revisión documental, trabajo de campo y la información obtenida de un foro en línea. Los resultados confirman que el desarrollo inmobiliario en zonas de reserva natural es el resultado de la inoperancia de la política de regulación del uso del suelo urbano, las inversiones pública y privada, la oferta de un grupo especializado de inmobiliarias y la demanda potencial de población con poder adquisitivo, y las condiciones biofísicas, la inestabilidad del terreno y la degradación medio ambiental se colocan como externalidades del modelo urbano privado de alta rentabilidad. Esta situación requiere de medidas de contención fundadas en principios de ordenamiento territorial y la participación de los distintos sectores sociales, que garanticen la transparencia y la aplicación de sanciones en materia de protección ecológica y ambiental, con el objeto de mantener en el largo plazo las condiciones de habitabilidad.

    Full Text Available La tecnología médica aplicada a la medicina del paciente agudo y grave permitió la creación de un área asistencial diferenciada y el desarrollo del cuidado intensivo como una nueva especialidad. Los nuevos medios disponibles para reemplazar o asistir funciones de órganos vitales fueron los determinantes de este avance tan importante en el desarrollo de toda la alta complejidad médica en los últimos cuarenta años. Sin embargo la aplicabilidad de estos medios, que en este caso son los soportes vitales, no se han podido sustraer de la filosofía del imperativo tecnológico que ha impregnado a toda la cultura de la sociedad contemporánea. Se observa en este tiempo una influencia perniciosa que perturba el recuerdo permanente de los fines de la medicina, que no son los de evitar la muerte o a la consideración del valor vida como un absoluto ajeno a las preferencias del paciente. Las decisiones finales en circunstancias irreversibles, en que sólo es posible mantener una vida biológica, deben ser tomadas por los médicos y los familiares.

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

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

    Science.gov (United States)

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

    2016-04-01

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

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.

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.

RESULTADOS: As alças apresentaram aumento da espessura da camada muscular acima e abaixo do ponto da operação. O estudo morfométrico comparativo das camadas musculares longitudinal e circular mostrou aumento significativo em comparação ao controle, não demonstrando significância entre os grupos B e C. CONCLUSÃO: Os resultados deste estudo revelaram importante aumento de espessura das camadas musculares, porém, menos acentuados que aqueles descritos na literatura quando foram realizados em animais submetidos à estenose fixa. Esses dados indicam que a construção operatória de piloros pela técnica utilizada promove alterações musculares de menor monta, possivelmente, pela função valvular do piloro.

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

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

    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.

Los homicidios de sindicalistas se han reducido en los últimos años debido a la desmovilización de parte del componente de las autodefensas y al repliegue de las guerrillas, y a su salida de zonas que disputaban con los paramilitares. Las bandas criminales también asesinan sindicalistas, pero en menor número.

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

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

    Full Text Available En el noroeste de México la producción de camarón cultivado es considerada como una de las más importantes de América Latina. 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. El impacto tiene un costo ambiental, económico y social y la pregunta que surge es si esto es sustentable en el tiempo.

A raíz de la entrada y convergencia con las nuevas tecnologías, el usuario ha podido comprobar su independencia creando su propia parrilla de programación, con opción a poder visionarla en cualquier momento, así como de experimentar una nueva faceta como productor y distribuidor de sus propios contenidos por Internet.Como resultado de la fusión de las tecnologías, se han hecho presentes nuevas herramientas de comunicación donde, si bien el espacio-tiempo ha dejado de ser prioritario, el poder de la imagen se ha perpetuado.Por otra parte la palabra escrita, que se encontraba eclipsada hasta hace unos años por el imperio de la imagen, ha resurgido a través de formas de expresión públicas como los llamados diarios electrónicos, mejor conocidos como ‘blogs’.Hoy en día el usuario de los medios ha podido comprobar las bondades de estas nuevas formas de comunicación pero también el uso amoral que el hombre puede hacer de ellas .En definitiva, la recepción audiovisual, el valor de los contenidos y el de la imagen en sí misma, han devenido y transformado al telespectador analógico en un usuario polivalente de los medios audiovisuales.

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. [en] Modernity as civilization and culture systems involves cognitive consensus. This study describes how media underpinned the construction of consensus and became a very important nexus between interpretation and meaning production. The main issue of the article is related to the ways which Latin America developed some of the modern arguments and their tendency to gather different propositions into a few discursive models, provoking a sort of convergence narrative. 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.

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

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

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

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

    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

  9. Fetal abdominal magnetic resonance imaging

    2006-01-01

    This review deals with the in vivo magnetic resonance imaging (MRI) appearance of the human fetal abdomen. Imaging findings are correlated with current knowledge of human fetal anatomy and physiology, which are crucial to understand and interpret fetal abdominal MRI scans. As fetal MRI covers a period of more than 20 weeks, which is characterized not only by organ growth, but also by changes and maturation of organ function, a different MR appearance of the fetal abdomen results. This not only applies to the fetal intestines, but also to the fetal liver, spleen, and adrenal glands. Choosing the appropriate sequences, various aspects of age-related and organ-specific function can be visualized with fetal MRI, as these are mirrored by changes in signal intensities. Knowledge of normal development is essential to delineate normal from pathological findings in the respective developmental stages

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

    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.

Gracias a esta y a muchas más razones la educación es posicionada como elemento fundante de la cultura. Teniendo en cuenta lo anterior, la educación sería un arma eficaz frente a cualquier expresión de crudeza y denigración contra la condi­ción humana, por parte de un individuo o colectivo, pues ella como camino de humanidad brinda las herramientas para alcanzar racionalidad y congruencia en el actuar de los individuos. Pero ¿qué sucede cuando los procesos educativos son desarrollados en escenarios complejos donde reina la barbarie? ¿Qué compromiso tienen las acciones educativas de un país que viven en medio de esta situación? La barbarie como acto esencialmente destructivo y fragmentador de la estructura social merece ser expues­to, reflexionado y denunciado desde el entorno escolar. Educar en medio de la barbarie: reflexiones y cuestionamientos, pretende disertar en torno al impacto que debe generarse en la educación cuando ésta se desarrolla en medio de espacios donde el conflicto, la violación y vulneración de derechos, las extremas muestras de crueldad, la completa pérdida de sensibilidad y consideración ante la condición del otro, se hace más que evidente. Todo este propósito desde el sustento teórico de autores como Adorno, Arendt y Reyes Mate, que ilustran esta oscura y compleja realidad.   Abstract Education is understood like a humanizing process, similarly it’s recognized as a tool of quality to con­science and evolution levels.

    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....

    2011-05-01

    Full Text Available Background: Many patients show modulation of tinnitus by gaze, jaw or neck movements, reflecting abnormal sensorimotor integration and interaction between various inputs. Postural control is based on multi-sensory integration (visual, vestibular, somatosensory, and oculomotor and indeed there is now evidence that posture can also be influenced by sound. Perhaps tinnitus influences posture similarly to external sound. This study examines the quality of postural performance in quiet stance in patients with modulated tinnitus.Methods: Twenty-three patients with highly modulated tinnitus were selected in the ENT service. Twelve reported exclusively or predominately left tinnitus, eight right and three bilateral. Eighteen control subjects were also tested. Subjects were asked to fixate a target at 40cm for 51s; posturography was performed with the platform (Technoconcept, 40Hz for both the eyes open and eyes closed conditions.Results: For both conditions, tinnitus subjects showed abnormally high lateral body sway (SDx. This was corroborated by fast Fourrier Transformation (FFTx and wavelet analysis. For patients with left tinnitus only, medio-lateral sway increased significantly when looking away from the center. Conclusions: Similarly to external sound stimulation, tinnitus could influence lateral sway by activating attention shift, and perhaps vestibular responses. Poor integration of sensorimotor signals is another possibility. Such abnormalities would be accentuated in left tinnitus because of the importance of the right cerebral cortex in processing both auditory-tinnitus and attention.

    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

    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.

  5. Dynamic CT in the abdominal organ, 1

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

  6. Review article: the functional abdominal pain syndrome.

    2011-03-01

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

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

    2014-07-01

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

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

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

    This study comprises 25 cases of blunt abdominal trauma proved by surgery. It is concluded that visceral damage by blunt abdominal trauma may be suspected, but can not be satisfactorily diagnosed upon a single plane abdominal roentgenologic examination with clinical support. Contrary to some reports in the literature, rupture of the hallow, viscus is more susceptible than solid organ and ileum is more than jejunum. It is a useful roentgenologic sign denoting distension and small cresent air shadow in the duodenal sweep of the damaged pancreas.

  18. Errors in abdominal computed tomography

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

    Full Text Available 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.

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

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

  18. Mechanisms and management of functional abdominal pain.

    Farmer, Adam D; Aziz, Qasim

    2014-09-01

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

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

    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.

  2. Abdominal MR: liver and pancreas

    1999-01-01

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

  3. Image mottle in abdominal CT.

    1999-04-01

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

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. The objective of this study was to determine the common characteristics related to patients with abdominal trauma. A study was conducted of 57 cases of abdominal trauma at the University Hospital of Maringá, during the period from January to December 2006. The majority of victims are male; the most affected age group is in its third decade of life; open abdominal trauma proved to be slightly more prevalent, and wounds from cold steel weapons were the most common; most abdominal injuries were due to traffic accidents; the conduct of surgical intervention overcomes conservative treatment

    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 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.

  11. Comportamiento anódico del cinc en medio tiosulfato

    Full Text Available In the last years, diverse studies about the cementation of gold with powder of zinc from thiosulphate and ammonia solutions have been carried out. The kinetic studies have concluded that during the process, the passivation of zinc particles takes place, causing the decrease of the gold cementation rate. For this reason, the anodic behavior of zinc in thiosulphate media was studied, using electrochemical techniques of linear potential sweep and potentiometry. The work was developed to different values of pH and thiosulphate concentrations, and the results were analyzed with scanning electronic microscopy. The polarization curves present 3 areas, an active dissolution area, a pseudo-passivation area and finally a reactivation area. The pseudo-passivation is caused by the formation of ZnS, which is dissolved for the action of OH- ions, originating the reactivation area.

    En los últimos años, se han realizado diversos estudios acerca de la cementación de oro con polvo de cinc desde soluciones de tiosulfato y amoniaco. Los estudios cinéticos establecieron que, durante el proceso, se produce la pasivación de la superficie de las partículas de cinc, provocando la disminución de la velocidad de cementación de oro. Por ello, se estudió el comportamiento anódico del cinc en medio tiosulfato, utilizando técnicas electroquímicas de barrido lineal de potencial y potenciometría. Se trabajó a diferentes valores de pH y concentraciones de tiosulfato, y los resultados fueron apoyados por microscopía electrónica de barrido. Se encontró que las curvas de polarización presentan tres zonas, una de disolución activa, una de pseudo-pasivación y, finalmente, una zona de reactivación. Se pudo identificar que la pseudo-pasivación es causada por la formación de ZnS, el cual se disuelve por la acción de iones, tales como el OH-, dando lugar a la zona de reactivación.

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

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

    2017-02-01

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

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

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

    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.

    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.

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

  2. Imaging the Abdominal Manifestations of Cystic Fibrosis

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    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.

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

The 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

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

  1. 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.

    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

  4. Abdominal Compartment Syndrome Secondary to Chronic Constipation

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

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

  11. Prophylactic antibiotics for penetrating abdominal trauma.

    Science.gov (United States)

    Brand, Martin; Grieve, Andrew

    2013-11-18

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

A revisão mostrou que a preservação intestinal está associada ao uso de soluções que fornecem substrato oxidativo para a célula assim como acrescentam substâncias que evitam ou reduzem a formação de espécies reativas de oxigênio. A hipotermia e a oxigenação destas soluções preservadoras é de uso corrente e consensual. Nove trabalhos ativeram-se ao uso específico da OHB. Não há consenso sobre sua utilização em trabalhos experimentais. Contudo os estudos não são comparáveis, pois utilizam metodologias diversas e diferentes tipos de avaliação. Discute-se também a complexidade e os custos da OHB. Apesar disto, há indicações que a OHB pode prevenir o edema da hipotermia, manter a oxigenação tecidual durante a preservação e impedir ou diminuir a formação de radicais livres. CONCLUSÃO: A OHB deve ser avaliada como alternativa exclusiva ou complementar às técnicas de preservação, sendo campo fértil de investigação.INTRODUCTION: In spite of the existence of several modalities of preservation, up to now a method that adequately keeps for a long time the quality and the functioning aspects of the small bowel to be transplanted is lacking. AIM: To gather articles using hyper baric

    Full Text Available Growth hormone (GH and glutamine (GLN are considered bowel trophic factors and are used experimentally after bowel resection. Their clinical uses in short bowel syndrome (SBS are still not standardized. It is of interest to verify metabolic, nutritional and side effects of the association of GH and GLN in SBS. Three patients, 39 (A, 33 (B, and 01 years old (C underwent bowel resection with jejunum anastomosis 15 cm (A and 60 cm (B distant from the Treitz angle, and 40 cm (C preserving the ileo cecal valve. GH Saizen (Serono - A, Genotropin (Pharmacia - B, and Norditropin (Novonordisk C were administered in doses of 0.14 mg /kg/day. GLN (0.4 g/kg/day was given orally for 10 days (A, 30 days (B and 60 days to patient C (0.28 g/kg/day. Central TPN and adequate oral diet was administered according to the bowel adaptation phase. On the first day after beginning treatment patient A exhibited symptoms of hypoglycemia. There were no other side effects. After treatment, body weight was higher and analysis by bioelectrical impedance showed more lean mass and less fat mass compared to pre-treatment measurements. Nitrogen retention was progressively higher with treatment. Simultaneous treatment with GH and GLN does not cause significant side effects, and is associated with a favorable distribution of the body compartments and nitrogen retention in patients with the short bowel syndrome.Hormônio de crescimento (GH e glutamina (GLN são fatores tróficos da mucosa intestinal, utilizados experimentalmente pós ressecção intestinal maciça.

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

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

    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

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

    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.

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

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

    2012-01-01

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

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

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

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

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

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

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

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

    Purpose: To evaluate CT in the diagnosis of abdominal abscess in children. Methods: Analysis of CT manifestations in 23 cases proved by operation and needle aspiration. Causes: acute appendicitis 13 cases, ascending colon perforation 1 case, Meckel diverticulitis 2 cases, cause obscured 7 cases. Bolus injection of contrast medium was given in 19 cases. Results: The CT value had no relationship to the course of disease and type of bacteria, amount of abscess had positive relevance relative with course of illness. Air-fluid level or scattered gas bubbles was seen in abscesses in 52%; little calcified plague was present in 22%. All cases presented nonhomogeneous thick wall enhancement after one week of illness. Conclusion: The characteristic CT features of intra-abdominal abscess were the presence of air and little calcified plague shadow; a large air-fluid level was indicative of fistula, while the absence of air in the abscess can not exclude fistula

    Fluid balance across the capillary membrane is maintained normally by a balance of hydrostatic and colloid osmotic pressures (COP). In 12 patients having major intra-abdominal procedures, the COP was followed during the operative and immediate postoperative periods. The patients' intraoperative fluid management consisted of replacing shed blood with blood and following Shires' concept of crystalloid replacement. Significant decreases in COP to approximately two thirds of the initial value occurred in patients having intra-abdominal procedures versus only a 10 percent decrease in those having peripheral procedures (greater than .001). As a result of this decrease in COP, the balance between hydrostatic and colloid osmotic pressures is lost and risk of pulmonary intersitial edema is increased.

    Intestinal tuberculosis is generally diagnosed using conventional barium studies, however recent diagnostic modalities such as ultrasonography and CT scan are widely applicated in conjunction with conventional studies for the search of lymph node presentation and associated extra-intestinal organs. It is important to differentiate intra-abdominal tuberculosis from metastatic or lymphomatous disease clinically. And it might be especially of worth to find out if there is any differential point between tuberculosis and other lymph nodal disease entities when we meet similar findings on imaging modalities. Authors have tried to evaluate ultrasonographic findings in conjunction with other studies in nine cases of abdominal tuberculosis which showed mainly extra-intestinal and/or lymph nodal involvement

    Full Text Available Schistosomiasis presenting as an abdominal mass with chronic pain in a child is not common. This report presents case of child presenting with schistosomiasis presenting as an abdominal mass with chronic pain. Abdominal ultrasonography did not particularly contribute to definitive pre-operative diagnosis. However, pathological examination of surgical specimen confirmed Schistosoma mansoni eggs in the biospy. A decrease in the mass volume was noticed under medical treatment (Biltricide. The aim of this report was to intimate clinicians on possible abdominal schistosomiasis as differential diagnosis of childhood abdominal mass. This is a clarion call for a high index of suspicion of childhood abdominal schistosomiasis in children presenting with abdominal mass in a tropical setting.

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

    In the appropriate clinical setting, certain aspects of extranodal abdominal lymphoma, as revealed by current cross-sectional imaging techniques, should be considered potentially diagnostic and can hasten the diagnosis. In addition, diagnostic imaging in the context of biopsy-proven lymphoma can accurately stage the disease for its appropriate treatment. The purpose of this article was to illustrate the various imaging aspects of extranodal lymphoma in the abdomen. (author)

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

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

    To provide the most recent and relevant clinical evidence regarding the use of prophylactic lung-protective mechanical ventilation in abdominal surgery. Evidence is accumulating, suggesting an association between intraoperative mechanical ventilation strategy and postoperative pulmonary complications in patients undergoing abdominal surgery. Nonprotective ventilator settings, especially high tidal volume (>10-12 ml/kg), very low level of positive end-expiratory pressure (PEEP, ventilator-associated lung injury in patients with healthy lungs. Stimulated by the previous findings in patients with acute respiratory distress syndrome, the use of lower tidal volume ventilation is becoming increasingly more common in the operating room. However, lowering tidal volume, though important, is only part of the overall multifaceted approach of lung-protective mechanical ventilation. Recent data provide compelling evidence that prophylactic lung-protective mechanical ventilation using lower tidal volume (6-8 ml/kg of predicted body weight), moderate PEEP (6-8 cm H2O), and recruitment maneuvers is associated with improved functional or physiological and clinical postoperative outcome in patients undergoing abdominal surgery. The use of prophylactic lung-protective ventilation can help in improving the postoperative outcome.

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

  20. Quantification of abdominal aortic deformation after EVAR

    Quantification of abdominal aortic deformation is an important requirement for the evaluation of endovascular stenting procedures and the further refinement of stent graft design. During endovascular aortic repair (EVAR) treatment, the aortic shape is subject to severe deformation that is imposed by medical instruments such as guide wires, catheters, and, the stent graft. This deformation can affect the flow characteristics and morphology of the aorta which have been shown to be elicitors for stent graft failures and be reason for reappearance of aneurysms. We present a method for quantifying the deformation of an aneurysmatic aorta imposed by an inserted stent graft device. The outline of the procedure includes initial rigid alignment of the two abdominal scans, segmentation of abdominal vessel trees, and automatic reduction of their centerline structures to one specified region of interest around the aorta. This is accomplished by preprocessing and remodeling of the pre- and postoperative aortic shapes before performing a non-rigid registration. We further narrow the resulting displacement fields to only include local non-rigid deformation and therefore, eliminate all remaining global rigid transformations. Finally, deformations for specified locations can be calculated from the resulting displacement fields. In order to evaluate our method, experiments for the extraction of aortic deformation fields are conducted on 15 patient datasets from endovascular aortic repair (EVAR) treatment. A visual assessment of the registration results and evaluation of the usage of deformation quantification were performed by two vascular surgeons and one interventional radiologist who are all experts in EVAR procedures.
