  1. Corpos estranhos provenientes de acessos cirúrgicos à cavidade abdominal: aspectos fisiopatológicos e implicações médico legais

    Directory of Open Access Journals (Sweden)

    Alberto Schanaider

    Full Text Available There is no large series about retained foreign bodies in abdominal cavity. In fact data are underestimated because of the lack of reports considering its serious medicolegal implications. An inflammatory fibrotic process inside the peritoneal cavity, a virtual discharge of inorganic material through the surgical incision and also a slow process of transmural migration into the intestinal lumen are the most frequent pathophysiologic situations. It is not uncommon the incidental diagnosis of foreign body and radiographic studies may be particularly helpful to elucidate the etiology. An early recognition minimizes the surgical risks and contributes to avoid severe complications. The best approach is to adopt preventive measures. Careful peroperative materials vigilance and instrumentation and also a meticulous check at the end of operations are essential to avoid such legal responsibility.

    Luiz Carlos Bertges

    Full Text Available Foram avaliados os resultados tardios da colocação de cálculos biliares humanos, de colesterol, na cavidade peritoneal de ratos. Constituíram-se cinco grupos: cinco ratos foram apenas laparotomizados com manuseio da cavidade; cinco foram laparotomizados e receberam um ponto com fio monofilamentar cinco zeros no sulco paracólico direito e mesentério; dez receberam cálculos que foram deixados livres na cavidade peritoneal; em dez, os clculos foram fixados no sulco paracólico direito e, finalmente, dez tiveram clculos fixados no mesentério. Os animais foram mortos após cinco meses de pós-operatório quando se observou a cavidade abdominal e foi coletado material para estudo histopatológico. Concluiu-se que os cálculos não foram absorvidos, desenvolveram uma reação peritoneal do tipo corpo estranho com formação de plastrão e foram envolvidos por tecido fibroso e células inflamatórias.

    Full Text Available Os estudos acadêmicos sobre cavidades naturais em formações ferríferas bandadas e canga, no Quadrilátero Ferrífero - Minas Gerais, são escassos diante do potencial espeleológico desta província mineral. Dentro deste contexto, as cavidades naturais da Serra da Piedade foram objeto de estudo, que tem como principal objetivo levantá-las e classificá-las, de acordo com seus aspectos morfológicos e genéticos, assim como analisar sua distribuição ao longo do relevo. Para isso, os seguintes procedimentos metodológicos foram realizados: (i revisão bibliográfica, (ii caracterização da área de estudo; (iii compartimentação do relevo; (iv prospecção e análise em campo dos aspectos morfológicos e genéticos; (v mensuração da projeção horizontal das cavidades, através de medidas realizadas em campo e mapeamento topográfico; e (vi análise e discussões dos resultados. Os resultados obtidos evidenciaram que existem três tipos de cavidades na Serra da Piedade: cavernas em tálus; cavernas com feições cársticas e cavernas onde não foi possível constatar evidências morfocársticas. De maneira geral, as cavidades formadas por acumulação de matacões encontram-se nos patamares altimétricos mais elevados, entretanto, estão situadas numa declividade relativamente suave. Já grande parte das cavernas sem evidências morfocársticas e das cavernas com feições cársticas estão localizadas na borda do platô de canga. Entretanto, a caverna cárstica de maior projeção horizontal está inserida no interior da unidade escarpa norte. Quanto ao desenvolvimento das cavernas topografadas, constatou-se que aquelas com feições cársticas são maiores do que as cavernas sem evidências morfocársticas.  Pode-se concluir que existem processos de carstificação em cavernas e feições superficiais desenvolvidas no itabirito e na canga, embora as mesmas não sejam tão desenvolvidas como as feições presentes em rochas carbon

    Full Text Available Amiloidose refere-se à deposição extracelular e progressiva de proteínas fibrilares patogênicas com características microscópicas e ultra-estruturais similares. A amiloidose pode ser sistêmica ou localizada. Descrevemos três pacientes que desenvolveram amiloidose intra-oral, sendo que dois casos manifestaram amiloidose localizada e o outro caso apresentou amiloidose sistêmica com acometimento de língua. Nos três casos, o exame histopatológico evidenciou depósitos de amilóide, os quais foram confirmados pela coloração de vermelho-congo. A ultra-estrutura mostrou material fibrilar compatível com amilóide. Apesar de infreqüente, a cavidade bucal pode ser um importante local de acometimento de amiloidose.

    Silva Alcino Lázaro da

    2001-01-01

    Full Text Available A lavagem da cavidade abdominal com solução salina 0,9% aquecida é uma prática comum em cirurgia geral, mas, geralmente, não há um controle adequado da sua temperatura, sendo por vezes introduzida na cavidade abdominal a temperaturas elevadas, possivelmente causando lesões no nível celular. O objetivo do trabalho é estudar a célula da parede posterior da cavidade abdominal de ratos após o tratamento desta com solução salina 0,9% aquecida a graus diversos. Foram utilizados 28 ratos divididos em três grupos com 9 animais cada e um rato controle. O grupo A foi tratado com solução salina 0,9% a 37ºC, o grupo B a 45ºC e o grupo C a 60ºC. O rato controle não recebeu tratamento com solução salina 09,%. Em todos os grupos a solução salina 0,9% permaneceu na cavidade durante 1 minuto. Exame histopatológico revelou que no rato controle e nos grupos A e B as fibras musculares e as estriações celulares estavam intactas. No grupo C, no entanto, observaram-se princípios de degeneração celular. Como conclusão ressalta-se a importância de um controle efetivo da temperatura da solução salina 0,9% a ser introduzida na cavidade abdominal de ratos para prevenir um trauma térmico no nível celular.

    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 JUSTIFICATIVA E OBJETIVOS: O óxido nitroso (N2O, por ser uma estrutura tri-atômica assimétrica, assume características de alta emissão e absorção de energia no espectro infra-vermelho, com um pico característico de absorção em 4,5 µm, o que o torna visível ao infra-vermelho curto, quando contrastado com uma fonte emissora de calor (anteparo quente. Diversos autores têm descrito a difusão do N2O para cavidades fechadas por métodos como cromatografia gasosa e analisador de gases, que não permitem um estudo macroscópico detalhado do gás. O presente estudo teve como objetivo a filmagem macroscópica no espectro infra-vermelho da difusão de N2O, utilizado em anestesia inalatória, para a cavidade peritoneal de ratos submetidos a pneumoperitônio de 20 mmHg com ar ambiente. MÉTODO: Dividiu-se os animais em três grupos, de acordo com o anestésico utilizado: I - controle venoso: tiopental intra-peritoneal; II - controle inalatório: isoflurano a 1,2% em O2 100%; III - óxido nitroso: N2O 66% em oxigênio e isoflurano a 0,6%. Os termogramas provenientes da descompressão abdominal foram obtidos, por meio de um radiômetro AGEMA 550 filmados a 7 quadros por segundo. RESULTADOS: O N2O demonstrou-se visível ao infra-vermelho. No momento da descompressão abdominal, não houve nos grupos I e II termogramas com rastros de gases visíveis ao infra-vermelho. Houve, porém, rastros de gases visíveis ao infra-vermelho no grupo III. CONCLUSÕES: Conclui-se que o óxido nitroso inalatório a 66% difundiu-se para a cavidade peritoneal de ratos submetidos a pneumoperitônio de 20 mmHg com ar ambiente, sem aumento de pressão intra-abdominal.JUSTIFICATIVA Y OBJETIVOS: El óxido nitroso (N2O, por ser una estructura tri-atómica asimétrica, toma características de alta emisión y absorción de energía en el espectro infrarrojo, con un pico característico de absorción en 4,5 µm, lo que lo hace visible al infrarrojo corto, cuando contrastado

    . Depending on the position of the epigastric trocar, the lifting equipment can interfere with the surgical instruments mobility. It may be necessary to reposition the support to perform the intra-operative cholangiography. The tensional force applied to the peritoneal surface by the lifting rods is small, and no additional post-operative pain was observed using this procedure. Conclusion - These results show that using the equipment described in this study, mechanical lifting of the abdominal wall is a feasible alternative for undertaking videolaparoscopic cholecystectomy.Racional - A suspensão mecânica da parede abdominal, método baseado no mecanismo de tração e conseqüente elevação da parede abdominal, é procedimento alternativo para a criação de adequado espaço intra-abdominal necessário à cirurgia videolaparoscópica, prescindindo-se da insuflação gasosa intra-peritonial. Objetivo - Avaliar a viabilidade técnica desse procedimento para realização da colecistectomia videolaparoscópica, com a análise de aspectos clínicos e funcionais da suspensão mecânica da parede abdominal. Pacientes e Métodos - Na Disciplina de Cirurgia do Aparelho Digestivo da Faculdade de Medicina da Universidade de São Paulo foi criado equipamento para realização de cirurgia videolaparoscópica por esse método, constituído de duas partes: a externa consiste em um pórtico acoplado à mesa operatória, no interior do qual desliza um cabo de aço que é tracionado por um sistema de catraca presente na extremidade inferior de uma das hastes do pórtico; a interna, o dispositivo suspensor, tem o formato em "L", cujo ramo horizontal é constituído de três hastes giratórias, o qual é conectado ao cabo de aço após introdução na cavidade abdominal. Com esse equipamento 10 pacientes foram submetidos a colecistectomia videolaparoscópica; em um deles foi associada hiatoplastia e fundoplicatura.

    Full Text Available El granuloma telangiectásico se considera como una lesión benigna no neoplásica de la mucosa gingival de tipo reactivo asociado a trauma. Durante varios años tuvo diferentes nombres dentro de los que destacan granuloma piógeno del embarazo o gravídico, hemangioma capilar lobular y épulis. Histológicamente se caracteriza por una proliferación vascular, infiltrado inflamatorio crónico y tejido de granulación. El objetivo del presente caso es describir las características clínicas e histológicas de un granuloma telangiectásico en cavidad oral y su plan de tratamiento. Llega a consulta paciente femenina de 50 años de edad, refiere presentar sangrado gingival en repetidas ocasiones en zona posterior de la arcada dentaria superior, durante el cepillado o con el consumo de algunos alimentos. Clínicamente se observa prótesis provisional desadaptada en órganos dentarios 11 al 15. Al retirar la prótesis es notorio un aumento de volumen en la encía interdental, con aspecto eritematoso, que sangra con facilidad. El reporte de anatomía patológica mostró una lesión con engrosamiento del epitelio escamoso, formación de nuevos vasos sanguíneos e infiltrado inflamatorio crónico. Diagnosticado como granuloma telangiectásico. La lesión fue eliminada quirúrgicamente por alargamiento coronal con reducción ósea. Ocho días después de la cirugía se evidencia proceso de cicatrización sin ninguna complicación. La lesión presentó recidiva transcurrido seis meses. Ello nos lleva a destacar la importancia del control de factores locales, como la presencia de prótesis desadaptadas y el acúmulo de placa bacteriana luego de la eliminación quirúrgica de este tipo de lesiones.

    Full Text Available Sorubim trigonocephalus Miranda et Ribeiro, 1920 conhecido popularmente como chinelo, é uma espécie migratória, de importância econômica. Bastante apreciado na gastronomia por apresentar sabor agradável e sem ossos intermusculares (espinhos. Os exemplares foram coletados em um trecho no Rio Teles Pires, localizado no município de Alta Floresta/MT. Anestesiados e sacrificados em solução aquosa de benzocaína, fixados com solução de formoldeído a 10%, transferidos para o Laboratório de Anatomia Animal/Unemat para descrição das características da cavidade bucofaringeana. Esta espécie apresentou uma pré-maxila bem desenvolvida e cabeça achatada dorsoventralmente, boca localizada na porção ventral média da cabeça, com fenda bucal ampla. Os lábios superiores apresentaram pigmentação cinza escuro com pequenas áreas claras, sendo mais largos que os inferiores e não apresentaram pigmentação. Foram identificadas quatro regiões dentígeras na porção anterior da cavidade bucal e duas na região da faringe, todas com dentes viliformes. A porção posterior da cavidade bucal era limitada lateralmente por quatro pares de arcos branquiais que decresciam em tamanho do primeiro ao último par, crânio-caudal, formados por dois ramos: o superior, mais curto, e o inferior, mais longo. A cavidade bucofaringeana de S. trigonocephalus se mostrou semelhante à de outros teleósteos descritos na literatura, estando adaptado ao hábito alimentar com dieta carnívoro-ictiofágica e diferindo apenas pela ausência de língua estrutural com pré maxila bem desenvolvida apresentando dentes viliformes.

  3. As principais lesões enegrecidas da cavidade oral

    Directory of Open Access Journals (Sweden)

    Rodrigo Gadelha Vasconcelos

    Full Text Available Introdução: as lesões pigmentadas podem ser encontradas na cavidade oral, essas pigmentações são provenientes de diversos fatores, tais como, locais, sistêmicos, fisiológicos ou patológicos. A cor, localização, distribuição e duração são características essenciais para o diagnóstico destas lesões, não devendo- se negligenciar a história médica, odontológica e familiar, bem como o consumo de drogas. Apesar de algumas lesões apresentarem características bastante específicas que as confere um diagnóstico apenas através do exame clínico, é importante que o profissional lance mão de métodos adicionais, como biópsias e exames laboratoriais, afim de alcançar um diagnóstico confiável e consequentemente, executar o tratamento adequado. Objetivos: essa revisão de literatura tem como objetivo discorrer sobre as principais lesões orais enegrecidas da cavidade oral, enfatizando o diagnóstico diferencial para cada uma delas, já que tal abordagem implicará diretamente na conduta profissional e no estabelecimento do tratamento adequado para cada paciente. Métodos: para isso foi realizada uma revisão de literatura através da busca de artigos no PubMED/Medline, Lilacs e Scielo. Resultados: a literatura estudada destacou que as lesões pigmentadas orais e maxilofaciais podem clinicamente simular o melanoma, uma lesão maligna. Conclusões: devemos ter especial atenção durante o exame clínico deste tipo de ocorrência, saber questionar o paciente para obter informações importantes a respeito da lesão, ter conhecimento dos diferentes tipos de lesões pigmentadas que acometem a cavidade oral e face, assim como ter em mente a necessidade do exame histopatológico para se obter o diagnóstico definitivo de lesões pigmentadas suspeitas.

Se calcula que cerca de 500 especies de bacterias habitan la cavidad oral humana, y alrededor de 22 géneros son los predominantes. Las bacterias que se aíslan con más frecuencia de los sitios infectados de la cavidad oral, y que son también patógenos potenciales, forma un grupo pequeño de microorganismos gramnegativos, entre los que se incluyen los siguientes: Actinobacillus actinomycetemcomitans, Bacteroides forsythus, Campylobacter spp., Capnocytophoga spp., Eikenella corrodens, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia y el grupo-Streptococcus milleri. E. corrodens se reconoce como un microbio patógeno oportunista en la cavidad oral; también, puede causar infecciones extra orales, como un agente infeccioso solo o en combinaciones con diversas bacterias. La presente revisión, con un énfasis en E. corrodens, mostrará varios aspectos de sus características microbiológicas y bioquímicas, también se sistematizan y discuten el conocimiento actual sobre los mecanismos de patogénesis, como los lipopolisacáridos, proteínas externas de membrana, complejo de adesina, pili y otros; infecciones oral y extra oral; factores predisponentes; endocarditis; osteomielitis, infecciones intra-abdominales; diagnóstico y agentes antimicrobianos.

    Full Text Available O objetivo deste estudo foi o de descrever os aspectos morfológicos e topográficos do Aparelho Digestório (AD de chinchilas, mediante a dissecação de dez animais. Os segmentos do AD foram coletados e demarcados, seguido de análise volumétrica dos órgãos cavitários, por meio de injeção de solução salina a 60 °C, além da mensuração dos comprimentos dos órgãos tubulares. Nos órgãos parenquimatosos realizou-se a sua pesagem. Durante a análise da disposição dos órgãos, evisceração e medição, observou-se que a cavidade oral é característica de roedores, as glândulas salivares são semelhantes às de lagomorfos e órgãos como esôfago, estômago, duodeno, cólon transverso, fígado, pâncreas e baço apresentam-se dispostos de forma semelhante ao descrito nas outras espécies. Já o jejuno e o cólon descendente foram evidenciados muito extensos e dispostos de forma ondulatória, suspensos no teto da cavidade abdominal. O íleo assemelhou-se ao descrito para as outras espécies, porém sua disposição topográfica é da direita para esquerda, direcionando-se ao ceco, o qual se constitui de duas porções distintas e bem desenvolvidas. Ambas as partes encontram-se localizadas à esquerda do plano mediano. O cólon ascendente dispõe-se de forma bastante particular, ocorrendo a presença de uma alça dupla que realiza um looping junto ao fígado. Uma característica relevante foi evidenciada ao comparar-se o reto de machos e fêmeas, o qual apresenta maior comprimento nos machos. De posse dos resultados concluímos que, apesar da chinchila ser um roedor, há características próprias da espécie e também outras que se assemelham aos lagomorfos, constituindo uma relação entre essas ordens.

    Full Text Available OBJETIVO: Alterações oculares, em especial a perda de volume nas cavidades evisceradas, promovem uma série de modificações ao paciente tanto funcional do órgão quanto psicológica e estética. Para tanto a procura de um material de baixo custo e com biocompatibilidade tem sido uma constante na literatura. Portanto, esse trabalho teve como objetivo testar experimentalmente implante de polietileno granulado de ultra-alto peso molecular, material de baixo custo, em órbitas de coelhos submetidos à evisceração cirúrgica em vários tempos experimentais, onde foram avaliados aspectos macroscópicos e microscópicose de toxicidade sistêmica do material. MÉTODOS: Para esse estudo foram utilizados coelhos Oryctolaguscuniculus submetidos à evisceração do globo ocular direito e posteriormente implantados com esfera de polietileno granulado de ultra-alto peso molecular e analisados por 15, 30, 90 e 180 dias pós-implante, com parâmetros macro, microscópios e bioquímicos. Os animais controles foram submetidos ao mesmo procedimento sem, entretanto a colocação do implante. RESULTADOS: Os resultados desse trabalho mostram que o material utilizado no implante de cavidade não apresenta alteração significativa nos parâmetros de peso e bioquímicos quando comparados ao grupo controle. O material implantado apresentou uma grande interação com o tecido do hospedeiro. CONCLUSÃO: Os resultados indicam que implante de polietileno granulado de alto peso molecular desenvolvido por uma indústria nacional tem alto potencial para se realizar testes em humanos.

    2003-08-01

    Intra-abdominal and extraperitoneal actinomycosis are rare infections, caused by different Actinomyces species. However, they have been diagnosed more frequently in the last ten years. We report three cases of abdominal actinomycosis and a literature review of the last eight years. All three patients were diagnosed by means of histopathologic examination only. In one case, an intrauterine device (IUD) was associated with the infection. Therapy consisted of surgical resection of the inflammatory, infected tissue, and long-term antibiotic therapy. All patients are free of recurrence. Abdominal actinomycosis should be included in the differential diagnosis of an abdominal pathology of insidious onset, especially when an IUD is in place. Even when infection had spread extensively, combined operative and antibiotic therapy cured most of the cases.

    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.

    Full Text Available RESUMO A infecção em cães por Dioctophyma renale, relatada em diversas partes do mundo, é considerada incomum, na maioria das vezes. No entanto, em algumas regiões são descritos números crescentes da infecção e muitos dados da epidemiologia e do ciclo biológico do parasito ainda são obscuros. Dessa forma, o trabalho tem como objetivo descrever os aspectos epidemiológicos, clinicopatológicos e ultrassonográficos de casos de infecção por Dioctophyma renale em cães na região da Fronteira Oeste do Rio Grande do Sul. Foram estudados 28 casos de dioctofimose em cães necropsiados ou clinicamente avaliados, submetidos à ultrassonografia e cirurgia para retirada dos parasitos. Os cães errantes foram os mais acometidos e todos com possível acesso às margens do Rio Uruguai. As lesões renais e extrarrenais foram caracterizadas predominantemente por atrofia do parênquima renal com glomerulonefrite esclerosante e peritonite granulomatosa associada a parasitos adultos livres na cavidade abdominal e ovos, bem como migrações erráticas para o tecido subcutâneo. Por fim, os achados ultrassonográficos corresponderam, especialmente, a imagens transversais circulares de até 0,6 cm de diâmetro, com margem hiperecoica e centro hipoecoico. Esses achados foram patognomônicos para infecção por Dioctophyma renale, e o exame ultrassonográfico se mostrou indispensável para o diagnóstico definitivo durante a avaliação clínica. Os achados observados nesse estudo demonstram a importância dessa parasitose na região. Além disso, alertam para a importância do diagnóstico, que vem sendo subestimado, além de apontar a necessidade de mais dados acerca da epidemiologia da doença para que se chegue a métodos efetivos de controle.

    Full Text Available OBJETIVO: Avaliar as características dos portadores de cavidades anoftálmicas que desenvolveram extrusão do implante. MÉTODOS: Estudo retrospectivo, observacional, tendo sido avaliados 37 portadores de cavidade anoftálmica que tiveram extrusão do implante de cavidade, na Faculdade de Medicina de Botucatu-UNESP. RESULTADOS: As extrusões ocorreram em cavidades enucleadas ou evisceradas, a maioria delas submetidas a cirurgia em decorrência de phthisis bulbi ou trauma, em geral de 1 a 2 anos após a cirurgia inicial. A deiscência precedeu a extrusão em todos os casos, tendo a extrusão ocorrido com todos os tipos de implantes empregados. CONCLUSÃO: Após a colocação de implantes de cavidade podem ocorrer complicações. A deiscência e extrusão das esferas são possibilidades que podem requerer nova intervenção cirúrgica, para a qual o paciente e o oftalmologista devem estar preparados.PURPOSE: To evaluate the characteristics of patients with anophthalmic cavity who developed sphere extrusion. METHODS: A retrospective observational study was done evaluating 37 patients with anophthalmic cavity and sphere extrusion at the "Faculdade de Medicina de Botucatu-UNESP". RESULTS: Extrusion was observed in enucleated and eviscerated cavities. The majority of the patients had the eye removed because of phthisis bulbi or trauma and the extrusion happened 1 or 2 years after the surgery. Extrusion was preceded by conjunctival dehiscence and exposure of the sphere and occurred with all used implants. CONCLUSION: Complications after orbital implant placement are a possibility. Dehiscence and sphere extrusion may happen and another surgery would be necessary. The patient and the ophthalmologist have to be prepared for this.

    disciplina fácil o que brinde resultados gratificantes con poco esfuerzo debido a las dificultades técnicas que ofrece la reconstrucción correcta de un elemento dentario destruido. Con frecuencia ocurren heridas pulpares durante el anclaje de los elementos adicionales de retención en cavidades complejas, agravadas por las dificultades técnicas que ocasiona la carencia de estos elementos, lo cual justifica la necesidad de simplificar los procederes dentales. Objetivo: Demostrar la factibilidad de la sustitución de los medios adicionales de anclaje por un surco retentivo en cavidades complejas de molares vitales en los que se necesite restaurar más de una cúspide. Métodos: Estudio observacional descriptivo a 53 pacientes (42 % del universo seleccionados mediante un muestreo aleatorio simple. Partiendo de una cavidad próximo-oclusal o MOD, las preparaciones cavitarias se extendieron en forma de cajas hacia región bucal o lingual y se sustituyeron los elementos adicionales de retención por un surco practicado en la pared gingival de la preparación. Se colocó hidróxido de calcio de fraguado rápido como forro cavitario, cemento de policarboxilato como base , y se realizó entonces la restauración de amalgama. Se precisó el número de restauraciones realizadas según la edad y el número de fracasos por fractura de la amalgama, pérdidas de la vitalidad y cambios periapicales teniendo en cuenta la edad y la evolución en un año. Resultados : La mayoría de las restauraciones de amalgama se realizaron en pacientes con edades comprendidas entre 35 y 59 años. Los valores de frecuencia relativa con que ocurrieron las fracturas de amalgama, pérdida de vitalidad y cambios periapicales fueron muy bajos.

    Full Text Available Resumen El embarazo ectópico abdominal secundario tiene una baja frecuencia de presentación en la práctica clínica, pero puede llevar al incremento de la mortalidad materna. Se presenta el caso de una paciente con embarazo abdominal secundario a una perforación uterina, causada por una interrupción voluntaria del embarazo. Este evolucionó durante nueve semanas con dolor abdominal y sangramiento vaginal escaso. A la paciente se le realizaron diagnósticos como enfermedad inflamatoria pélvica aguda, infección del tracto urinario, restos ovulares post aborto y definitivamente se concluyó como embarazo ectópico abdominal mediante ecografía abdominal. Se le realizó laparotomía exploradora y se extrajo el feto y la placenta sin dificultades con una evolución postoperatoria favorable hacia la curación. Se concluyó que la perforación uterina durante el curetaje de la cavidad pudo pasar inadvertida, llevando a implantación abdominal secundaria del embarazo con un cuadro clínico variable. En dicho cuadro, el ultrasonido juega un papel fundamental para su diagnóstico, siendo el manejo laparotómico el más apropiado en estos casos.

    Full Text Available Background: Abdominal epilepsy (AE is an uncommon cause for chronic recurrent abdominal pain in children and adults. It is characterized by paroxysmal episode of abdominal pain, diverse abdominal complaints, definite electroencephalogram (EEG abnormalities and favorable response to the introduction of anti-epileptic drugs (AED. We studied 150 children with chronic recurrent abdominal pain and after exclusion of more common etiologies for the presenting complaints; workup proceeded with an EEG. We found 111 (74% children with an abnormal EEG and 39 (26% children with normal EEG. All children were subjected to AED (Oxcarbazepine and 139 (92% children responded to AED out of which 111 (74% children had an abnormal EEG and 27 (18% had a normal EEG. On further follow-up the patients were symptom free, which helped us to confirm the clinical diagnosis. Context: Recurrent chronic abdominal pain is a common problem encountered by pediatricians. Variety of investigations are done to come to a diagnosis but a cause is rarely found. In such children diagnosis of AE should be considered and an EEG will confirm the diagnosis and treated with AED. Aims: To find the incidence of AE in children presenting with chronic recurrent abdominal pain and to correlate EEG findings and their clinical response to empirical AEDs in both cases and control. Settings and Design: Krishna Institute of Medical Sciences University, Karad, Maharashtra, India. Prospective analytical study. Materials and Methods: A total of 150 children with chronic recurrent abdominal pain were studied by investigations to rule out common causes of abdominal pain and an EEG. All children were then started with AED oxycarbamezepine and their response to the treatment was noted. Results: 111 (74% of the total 150 children showed a positive EEG change suggestive of epileptogenic activity and of which 75 (67.56% were females and 36 (32.43% were male, majority of children were in the age of group of 9

    Full Text Available Abdominal compartment syndrome (ACS increases the risk for mortality in critically ill children. It occurs in association with a wide variety of medical and surgical diagnoses. Management of ACS involves recognizing the development of intra-abdominal hypertension (IAH by intra-abdominal pressure (IAP monitoring, treating the underlying cause, and preventing progression to ACS by lowering IAP. When ACS is already present, supporting dysfunctional organs and decreasing IAP to prevent new organ involvement become an additional focus of therapy. Medical management strategies to achieve these goals should be employed but when medical management fails, timely abdominal decompression is essential to reduce the risk of mortality. A literature review was performed to understand the role and outcomes of abdominal decompression among children with ACS. Abdominal decompression appears to have a positive effect on patient survival. However, prospective randomized studies are needed to fully understand the indications and impact of these therapies on survival in children.

A saliva possui diversas funções, incluindo reparação tecidual, tamponamento, proteção, digestão, gustação, ação antimicrobiana, manutenção da integridade do dente e sistema de defesa antioxidante. A redução do fluxo salivar (hipossalivação é um distúrbio comum, e estima-se que cerca de 20% da população geral tenham esta alteração. A hipossalivação pode ser decorrente de diabetes mellitus, hipotireoidismo, desidratação, comprometimento do parênquima glandular por processos infecciosos, doenças granulomatosas ou condições autoimunes e inflamatórias (como a síndrome de Sjögren e a artrite reumatoide, radioterapia da região cefálica e/ou cervical, bem como pode estar associada a distúrbios do humor, efeitos adversos ocasionados pelo uso de algumas medicações ou, ainda, ser de causa idiopática. As terapias convencionais para o tratamento da redução do fluxo salivar, com o uso de sialogogos gustatórios e químicos, ainda apresentam restrições. Contudo, novas alternativas têm mostrado grande perspectiva no tratamento deste problema. Diagnosticar um paciente como hipossalivador crônico é um desafio na prática clínica, e os métodos de avaliação do fluxo salivar são pouco conhecidos pelos reumatologistas. A avaliação seriada do fluxo salivar é importante para o correto diagnóstico e prognóstico de determinadas condições bucais e sistêmicas. Esta revisão aborda alguns aspectos relacionados à função da saliva, às consequências da hipossalivação e aos métodos de medição da taxa de fluxo salivar, conceitos úteis na prática diária do reumatologista.

    Full Text Available Los neurilemomas son tumores neurogénicos benignos, con origen en la vaina neural. De los neurilemomas extracraneales, aproximadamente un 25 a un 45% ocurren en cabeza y cuello. La edad de afectación predominante es entre la tercera y la cuarta décadas de vida. El neurilemoma es un tumor claramente circunscrito y, generalmente, de pequeño tamaño. Clínicamente aparece como una masa de crecimiento lento y gradual. El examen microscópico es necesario para el diagnóstico. El tratamiento de elección es la escisión quirúrgica completa tumoral y después de ésta es muy rara su recurrencia. El propósito de este artículo es presentar un estudio retrospectivo, de nueve casos, de neurilemomas de cavidad oral y cuello, tratados en nuestro servicio de Cirugía Oral y Maxilofacial, entre 1997 y 2001. Hemos valorado una serie de parámetros epidemiológicos (edad, sexo, localización, tamaño, clínica, estudios previos a la cirugía, tiempo trascurrido entre aparición de síntomas y primera consulta, nervio de origen, patrón histológico predominante (Antoni A, Antoni B, y evolución postquirúrgica. Se ha realizado una revisión de la literatura.Neurilemomas are benign neurogenic tumours, that derive from the neural sheath. Approximately 25 to 45 per cent of the extracraneal neurilemomas occur in the head and neck region. Neurilemomas usually occur between the third and the fourth decades of life. Neurilemoma is a sharply circumscribed, and usually small tumor. Clinically it manifests as a slow and gradually growing mass; microscopic examination is neccesary for diagnosis. Complete tumoral excision remains the treatment of choice and after this, they rarely recur. The aim of this article is to report a retrospective study, of nine cases, of oral cavity and neck neurilemomas, treated in our service of Oral and Maxillofacial Surgery, between 1997 and 2001.

    In this paper a two dimensional numerical study on heat transfer by conduction and convection in a shallow inclined cavity with a semi-transparent wall is presented, where the region between the glass cover (GC) and the absorber plate resembles a cavity. The absorber plate is considered an isothermal surface at hot temperature; whereas the vertical walls were considered adiabatic. The thermal physical and optical properties of the glass cover (GC) were taken into account for the analysis. Inclination angles from 15 degrees to 35 degrees, aspect ratios (A) of 8 and 12 and Rayleigh numbers 10 4, 10 5 and 10 6 were combined to construct the cases. The governing equations of mass, moment and energy were discretized by the use of the Finite Volume method solving the algebraic equations with the SIMPLE algorithm. Results displayed include isotherms and streamlines inside the cavity, as well as temperature distribution on the inside surface of the glass cover (GC) and Nusselt number variations regarding the inclination angle for the two aspect ratios. The results show that the heat transfer increases while the inclination angle rise up, except for the cases where A=8,12, Ra=10 4 and {lambda}=30 where a transition of the flow pattern occurs, and the heat transfer diminishes with the aspect ratio for a fixed Rayleigh.

    Reconstruction with reconstitution of the container function of the abdominal compartment is increasingly being performed in patients with massive ventral hernia previously deemed inoperable. This situation places patients at great risk of severe intra-abdominal hypertension and abdominal compartment syndrome if organ failure ensues. Intra-abdominal hypertension and especially abdominal compartment syndrome may be devastating systemic complications with systematic and progressive organ failure and death. We thus reviewed the pathophysiology and reported clinical experiences with abnormalities of intra-abdominal pressure in the context of abdominal wall reconstruction. Bibliographic databases (1950-2015), websites, textbooks, and the bibliographies of previously recovered articles for reports or data relating to intra-abdominal pressure, intra-abdominal hypertension, and the abdominal compartment syndrome in relation to ventral, incisional, or abdominal hernia repair or abdominal wall reconstruction. Surgeons should thus consider and carefully measure intra-abdominal pressure and its resultant effects on respiratory parameters and function during abdominal wall reconstruction. The intra-abdominal pressure post-operatively will be a result of the new intra-peritoneal volume and the abdominal wall compliance. Strategies surgeons may utilize to ameliorate intra-abdominal pressure rise after abdominal wall reconstruction including temporizing paralysis of the musculature either temporarily or semi-permanently, pre-operative progressive pneumoperitoneum, permanently removing visceral contents, or surgically releasing the musculature to increase the abdominal container volume. In patients without complicating shock and inflammation, and in whom the abdominal wall anatomy has been so functionally adapted to maximize compliance, intra-abdominal hypertension may be transient and tolerable.

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

    Abdominal wall hernias are common diseases of the abdomen with a global incidence approximately 4%-5%. They are distinguished in external, diaphragmatic and internal hernias on the basis of their localisation. Groin hernias are the most common with a prevalence of 75%, followed by femoral (15%) and umbilical (8%). There is a higher prevalence in males (M:F, 8:1). Diagnosis is usually made on physical examination. However, clinical diagnosis may be difficult, especially in patients with obesity, pain or abdominal wall scarring. In these cases, abdominal imaging may be the first clue to the correct diagnosis and to confirm suspected complications. Different imaging modalities are used: conventional radiographs or barium studies, ultrasonography and Computed Tomography. Imaging modalities can aid in the differential diagnosis of palpable abdominal wall masses and can help to define hernial contents such as fatty tissue, bowel, other organs or fluid. This work focuses on the main radiological findings of abdominal herniations. PMID:21860678

    Full Text Available O presente trabalho tem como objetivo interpretar o contexto geográfico associado à ocorrência de cavidades nos quartzitos da região sudeste de Diamantina/MG - Serra do Espinhaço Meridional. O procedimento metodológico foi composto por revisão bibliográfica; levantamento cartográfico; trabalhos de campo; topografia das cavidades; levantamento das linhas estruturais na área externa e no interior das cavidades; petrografia; coleta, laminação e análise química qualitativa de depósitos químicos e interpretação do contexto geográfico de inserção das cavidades. Os resultados obtidos demonstram que a ocorrência de feições cársticas na área de estudo pode estar relacionada a um conjunto de fatores. Assim, a presença de poliminerais, como mica e feldspato; diferentes camadas estratigráficas da Formação Sopa-Brumadinho (quartzitos monomíticos e conglomerados; os lineamentos estruturais e as características geomorfológicas locais são fatores que contribuem para a ocorrência de cavidades na região. A hipótese de formação das cavidades indica a probabilidade de ocorrência de dissolução, produção de materiais inconsolidados, lixiviação, remobilização dos grãos alterados e ampliação dos condutos através de abatimentos.

    Interaction of natural convection and radiation heat transfer in an open side square cavity has been simulated numerically. Previous studies have shown results of the simulation of heat transfer for convection on this geometry. This paper reports the effect of considering both the convection and the radiation mechanisms. Radiation was found to have a great influence on the total amount of heat lost by the cavity as well as on the pattern of flow and on the temperature field. Computations were performed within the domain of the cavity for two-dimensional laminar flow problem. The average of heat transfer coefficient was calculated for several values of the Grashof number for air (Pr = 0.7), with the bottom wall at 500 K (constant temperature) and the open side at 300 K. [Spanish] Se presenta el estudio de la interaccion conveccion natural-radiacion en una cavidad rectangular abierta. Algunos estudios anteriores han mostrado resultados sobre la transferencia de calor por el mecanismo de conveccion natural sobre cavidades abiertas. Aqui se presenta la influencia de considerar ambos mecanismos de transferencia de calor, la conveccion y la radiacion. Se demuestra que el intercambio radiactivo tiene una gran influencia tanto en la cantidad total de calor perdido por la cavidad al ambiente, como en el patron de flujo y de temperatura dentro de la cavidad. Se resuelven numericamente las ecuaciones gobernantes para flujo laminar en dos dimensiones y se calcula el coeficiente promedio de transferencia de calor para diferentes valores del Grashof en una cavidad llena de aire (Pr 0.7), teniendo la pared del fondo de la cavidad a 500 K y los alrededores a 300 K.

    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

    Endometriosis of abdominal wall scar following operation on uterus and tubes is extremely rare. The late onset of symptoms after surgery is the usual cause of misdiagnosis. Scar endometriosis is a rare disease which is difficult to diagnose and should always be considered as a differential diagnosis of painful abdominal masses in women. The diagnosis is made only after excision and histopathology of the lesion. Preoperative differentials include hernia, lipoma, suture granuloma or abscess. Hence an awareness of the entity avoids delay in diagnosis, helps clinicians to a more tailored treatment and also avoids unnecessary referrals. We report a case of abdominal endometriosis. The definitive diagnosis of which was established by histopathological studies.

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

  13. [The abdominal catastrophe].

    Patients with an abdominal catastrophe are in urgent need of early, interdisciplinary medical help. The treatment plan should be based on medical priorities and clear leadership. First priority should be given to achieve optimal oxygenation of blood and stabilization of circulation during all treatment-phases. The sicker the patient, the less invasive the (surgical) treatment should to be, which means "damage control only". This short article describes 7 important, pragmatic rules that will help to increase the survival of a patient with an abdominal catastrophe. Preexisting morbidity and risk factors must be included in the overall risk-evaluation for every therapeutic intervention. The challenge in patients with an abdominal catastrophe is to carefully balance the therapeutic stress and the existing resistance of the individual patient. The best way to avoid abdominal disaster, however, is its prevention.

    Full Text Available Monoculturas de árvores, como as de espécies de eucalipto, têm substituído florestas naturais, impactando a fauna pela perda de habitat e recursos. Diversas espécies de aves necessitam de ocos em árvores para nidificar. A falta de recursos como cavidades formadas pela degradação da árvore ou locais apropriados para serem criadas cavidades leva a diminuição na abundância das populações destas espécies. Este trabalho tem o objetivo de comparar a riqueza e a densidade de aves que nidificam em ocos em áreas de plantação de eucalipto abandonadas com áreas de vegetação nativa em duas unidades de conservação em Minas Gerais. Em cada tipo de vegetação de cada reserva foram estabelecidos 25 pontos, nas quais foi utilizado o método de contagem por remoção para o levantamento das espécies de aves. A riqueza de espécies de aves de cada área foi estimada por Jackniffe e a densidade foi estimada através do método de máxima verossimilhança; modelos candidatos que poderiam influenciar a abundância das aves foram avaliados utilizando-se o Critério de Informação Akaike (AIC. Os resultados mostraram que a riqueza de espécies foi maior nas áreas de florestas nativas e que a densidade foi significantemente mais alta nas áreas de florestas nativas, e que o tipo de vegetação e a hora do dia influenciam na abundância e detecção das aves. Esses resultados indicam que as plantações de eucaliptos influenciam negativamente a comunidade de aves que nidificam em ocos, provavelmente por causa da falta de cavidades ou de sub-bosque. Plantações de eucaliptos normalmente não substituem as florestas nativas e seu uso deve ser controlado em áreas de conservação.

    Three cases of blunt abdominal trauma are presented to exemplify the mechanism of trauma and the problems of diagnosis associated with any linear blow to the abdomen. The mechanisms of visceral injury are reviewed, and special attention is directed to the abdominal wall injury that can be present in these patients. This injury has special implications in directing the operative approach and repair. An unusual aortic occlusion is described which is peculiar to this type of injury.

    Full Text Available A 63-year-old Caucasian female patient presented with redness of the both foot and lower legs, as well as edema of the left lower leg, accompanied by subjective complaints of burning. Fever was not reported. Well-circumscribed oval shaped tumor formation was revealed also on the abdominal wall, with hyperpigmented and depigmented areas on its ulcerated surface, measuring approximately 10/10cm in diameter, with soft-elastic texture on palpation.  The lesion occurred in 2011, according to the patient’s history. No subjective complaints were reported in association. The performed ultrasonography revealed intestinal loops in the hernial sac, without incarceration. The diagnosis of ventral abdominal hernia without mechanical ileus was made. The patient was referred for planned surgical procedure, because of her refusal on this stage.The clinical manifestation of the tumor formation on the abdominal wall, required wide spectrum of differential diagnosis, including aneurysm of the abdominal aorta, abdominal tumor, subcutaneous tumor or metastasis or hernia. In the presented cases, the abdominal wall mass was a sporadic clinical finding in the framework of the total-body skin examination in patient with erysipelas. The lack of subjective symptoms, as well as the reported history for hysterectomy and previously abscessus were not enough indicative symptoms for the correct diagnosis. The diagnosis of non-complicated hernia was made via ultrasonography, while the clinical differentiation between hernia and other life-threatening conditions as aneurysms or tumor was not possible.

    The damage control surgery, with emphasis on laparostomy, usually results in shrinkage of the aponeurosis and loss of the ability to close the abdominal wall, leading to the formation of ventral incisional hernias. Currently, various techniques offer greater chances of closing the abdominal cavity with less tension. Thus, this study aims to evaluate three temporary closure techniques of the abdominal cavity: the Vacuum-Assisted Closure Therapy - VAC, the Bogotá Bag and the Vacuum-pack. We conducted a systematic review of the literature, selecting 28 articles published in the last 20 years. The techniques of the bag Bogotá and Vacuum-pack had the advantage of easy access to the material in most centers and low cost, contrary to VAC, which, besides presenting high cost, is not available in most hospitals. On the other hand, the VAC technique was more effective in reducing stress at the edges of lesions, removing stagnant fluids and waste, in addition to acting at the cellular level by increasing proliferation and cell division rates, and showed the highest rates of primary closure of the abdominal cavity. RESUMO A cirurgia de controle de danos, com ênfase em peritoneostomia, geralmente resulta em retração da aponeurose e perda da capacidade de fechar a parede abdominal, levando à formação de hérnias ventrais incisionais. Atualmente, várias técnicas oferecem maiores chances de fechamento da cavidade abdominal, com menor tensão. Deste modo, este estudo tem por objetivo avaliar três técnicas de fechamento temporário da cavidade abdominal: fechamento a vácuo (Vacuum-Assisted Closure Therapy - VAC), Bolsa de Bogotá e Vacuum-pack. Realizou-se uma revisão sistemática da literatura com seleção de 28 artigos publicados nos últimos 20 anos. As técnicas de Bolsa de Bogotá e Vacuum-pack tiveram como vantagem o acesso fácil ao material, na maioria dos centros, e baixo custo, ao contrário do que se observa na terapia a vácuo, VAC, que além de apresentar

MÉTODOS: Dezoito pacientes foram avaliados qualitativa e quantitativamente na Faculdade de Medicina de Botucatu - Universidade Estadual Paulista - UNESP, com e sem a prótese externa. Usando imagens obtidas por filmadora e processadas usando o programa Scion Image, mediu-se a altura do sulco palpebral superior, a altura da fenda palpebral e os ângulos palpebrais dos cantos interno e externo. RESULTADOS: Pseudo-estrabismo e sulco palpebral superior profundo foram as alterações mais freqüentes ao exame externo. Houve diferença significativa em todas as variáveis estudadas, com diminuição da altura do sulco palpebral superior, aumento da área da fenda palpebral e aumento dos ângulos palpebrais interno e externo quando o paciente estava usando a prótese externa. CONCLUSÃO: Todos os pacientes avaliados apresentaram algum tipo de anormalidade órbito-palpebral, o que reflete a dificuldade em se proporcionar ao portador de cavidade anoftálmica um aspecto idêntico ao que existe na órbita normal. O processamento de imagens digitais permitiu avaliação objetiva das dimensões óculo-palpebrais, o que poderá contribuir nas avaliações seqüenciais dos portadores de cavidade anoftálmica.PURPOSE: The authors intend to evaluate the eyelid position before and after the external prosthesis adaptation, using digital image processing techniques.

    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.

    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

    We report a case of abdominal actinomycosis in a 54 year old woman using an intrauterine device for a period of 8 years. The most important finding was a tuboovarialabscess at the left pelvic side with involvement of the serosa of the jejunum, ileum, sigma, and omentum majus. Intraoperative exploration showed a solid retroperitoneal infiltration between the pelvic side wall and sigma. Another infiltration was found on the left side of the abdominal wall. The diagnosis was confirmed by histopathological examination and the patient was treated by a combination of Aminopenicillin and Metronidazol. After a period of three months we observed a complete regression of the clinical and the MRI findings.

  12. 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.

    2009-02-01

    Full Text Available Cistos congênitos mediastinais são lesões benignas incomuns, geralmente causadas por falhas no desenvolvimento embriológico do intestino anterior e/ou da cavidade celômica. São formações expansivas, comumente assintomáticas, mas que podem se manifestar principalmente pela compressão de estruturas adjacentes. Entre as principais entidades deste grupo temos: cistos broncogênico, pericárdico, entérico e tímico, linfangioma e cisto de duplicação esofágica. A morfologia dos cistos congênitos mediastinais é típica, sendo os exames de imagem suficientes, em grande parte dos casos, para a confirmação diagnóstica. O tratamento cirúrgico está indicado apenas nos casos sintomáticos, pois estas lesões não apresentam potencial de degeneração maligna. O objetivo deste trabalho é comentar e ilustrar os aspectos de imagem mais relevantes destas lesões, a partir do estudo retrospectivo de dez casos de arquivo das instituições envolvidas.Congenital mediastinal cysts are uncommon benign lesions generally caused by an abnormal embryological development of the foregut or coelomic cavity. They are expansive lesions, frequently asymptomatic that may manifest as a result from compression of adjacent structures. Bronchogenic, pericardial, enteric, thymic, esophageal duplication cysts and lymphangiomas are the main entities in this group of lesions. Congenital mediastinal cysts morphology is typical and imaging methods allow a correct diagnosis in a great number of cases. Surgical treatment is indicated only in cases of symptomatic lesions, considering that these lesions present no potential for malignant degeneration. The present study was aimed at commenting and illustrating the most relevant imaging findings of these lesions based on a retrospective review of ten cases collected in the records of the involved institutions.

    Full Text Available Los quistes del mesenterio son lesiones benignas intrabdominales que crecen a expensas de los vasos linfáticos del intestino; son más frecuentes en el mesenterio ileal y muy raros en la edad pediátrica. El síndrome abdominal agudo en la edad pediátrica es difícil de definir al ser un cuadro de origen múltiple y de presentación clínica muy variada; su síntoma principal es el dolor abdominal agudo, una de las causas que con mayor frecuencia motivan consulta en el Servicio de Urgencias Pediátricas. Los quistes de mesenterio son infrecuentes, se estima que se presentan en uno de cada 100 000 ingresos por síndrome abdominal agudo en pediatría. El estudio de elección para el diagnóstico es el ultrasonido abdominal y el tratamiento óptimo es la resección completa del quiste. Se presenta el caso de una paciente con tumor abdominal ingresada para su estudio. Durante su evolución tuvo datos de irritación peritoneal por lo que se decidió realizar una laparotomía exploradora en la que se encontró un quiste del mesenterio, roto e infectado. Se efectuó hemicolectomía izquierda, lavado de cavidad y colostomía de una sola boca. A los tres meses de operada se hizo la restitución del tránsito intestinal con buenos resultados.

    Background: Abdominal auscultation has an important position in the physical examination of the abdomen. Little is known about rater agreement. The aim of this study was to describe rater agreement and thus, indirectly, the value of the examination. Methods: In a semi-virtual setup 12 recordings...... of the intestinal sounds from 8 patients with acute abdominal pain and 4 healthy volunteers were presented to 100 physicians. The physicians were asked to characterize the intestinal sounds as normal or pathologic. Fisher's exact test was used for comparison between groups of physicians. Results: Overall, 72......% of the answers with regard to healthy volunteers concluded that the sounds were normal (equalling agreement), whereas 64% of answers with regard to intestinal obstruction concluded that the sounds were pathologic (but agreement was higher due to agreement on wrong diagnosis in one case). Bowel sounds from...

DESCRIÇÃO DO CASO: Paciente de 18 meses deu entrada à emergência com dor abdominal e vômitos há 48 horas. O exame abdominal revelou dois orifícios e massa pequena endurecida. O raio X de abdome mostrou imagem compatível com três objetos metálicos. Duas agulhas e um prego sem cabeça foram removidos da cavidade abdominal por meio de laparotomia. COMENTÁRIOS: O diagnóstico foi realizado no segundo atendimento médico, provavelmente por não ter sido aventada a possibilidade de lesão intencional no primeiro. A violência física é um diagnóstico diferencial a ser pensado nos quadros de dor abdominal em crianças. Ressalta-se a importância de aprimorar a formação do residente de Pediatria e dos pediatras em geral para a abordagem da violência contra a criança, de forma que estejam mais preparados para o acionamento da linha de cuidado em situações de violência.OBJETIVO: Alertar a los pediatras y médicos internos en Pediatría respecto a la posibilidad de ocurrencia de violencia contra el niño por medio del relato de un caso clínico.

    2010-06-01

    Ruptured abdominal aortic aneurysm (AAA) continues to be one of the most lethal vascular pathologies we encounter. Its management demands prompt and efficient evaluation and repair. Open repair has traditionally been the mainstay of treatment. However, the introduction of endovascular techniques has altered the treatment algorithm for ruptured AAA in most major medical centers. We present recent literature and techniques for ruptured AAA and its surgical management.

    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.

    2016-05-01

    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation.

    Science.gov (United States)

    Frei, Pascal

    2015-09-02

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

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

    2002-09-01

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

    Full Text Available OBJETIVO: Avaliar experimentalmente a biocompatibilidade de cones de biovidro e biovitrocerâmico em cavidades evisceradas de coelhos. MÉTODOS: Foram utilizados 45 coelhos albinos submetidos à cirurgia de evisceração do olho direito, seguida da inclusão de cones de biovidro e dois tipos de biovitrocerâmicos (chamados de FI e FII na cavidade escleral. Os animais foram sacrificados em três momentos (7, 90 e 180 dias. Os parâmetros avaliados foram: peso, exame clínico diário, exames bioquímicos, avaliação histológica, exame morfométrico. RESULTADOS: Os animais mantiveram-se saudáveis durante o experimento, não tendo ocorrido extrusão do implante em nenhum animal. O exame morfológico mostrou que houve a formação de pseudocápsula ao redor dos cones, com superioridade dos cones de biovidro e biovitrocerâmico FI, os quais apresentaram menor reação inflamatória e menor formação da pseudocápsula ao redor dos cones que os demais. A reação inflamatória foi mais intensa após 7 dias da colocação dos cones, diminuindo em direção aos 180 dias, sendo menos intensa nos coelhos que receberam cones de biovidro. CONCLUSÃO: Os cones de biovidro e biovitrocerâmico FI e FII podem ser úteis para a reparação da cavidade anoftálmica, com melhor resposta quando se usa cones de biovidro e de biovitrocerâmico FI.

    Cervellin, Gianfranco; Lippi, Giuseppe

    2015-06-01

    Although traditionally regarded as a specific pediatric disease, abdominal migraine may also be observed in adults. Unfortunately, however, this condition is frequently overlooked in the differential diagnosis of abdominal pain in the emergency department (ED). A 30-year-old woman presented to our ED complaining of abdominal pain and vomiting, lasting for 12 hours. The pain was periumbilical, continuous, and not associated with fever or diarrhea. The physical examination and the results of conventional blood tests were normal. The patient was treated with intravenous ketoprofen, metoclopramide, and ranitidine, obtaining a prompt relief of symptoms. She had a history of similar episodes in the last 15 years, with several ED visits, blood test examinations, ultrasonography of the abdomen, and upper gastrointestinal endoscopies. Celiac disease, porphyry, sickle cell disease, and inflammatory bowel disease were all excluded. In July 2012, she became pregnant, and she delivered a healthy baby on April 2013. Until November 2014, she has remained asymptomatic. Based on the clinical characteristics of the abdominal pain episodes, the exclusion of any alternative diagnosis, and the relief of symptoms during and after pregnancy, a final diagnosis of abdominal migraine could be established. A skilled emergency physician should always consider abdominal migraine in the differential diagnosis of patients admitted to the ED with abdominal pain, especially when the attacks are recurrent and no alternative diagnosis can be clearly established.

La presentación clínica de nuestros dos pacientes es singular ya que solo poseían lesiones en la cavidad oral. La respuesta al tratamiento instaurado fue buena.Syphilis is a human infectious disease caused by the bacterium Treponema pallidum. The disease is transmitted by direct contact with a lesion during the primary or secondary stages, in utero by the transplacental route, or during delivery as the baby passes through an infected canal. The bacterium may infect any organ, causing an infinite number of clinical presentations. Secondary syphilis is characterized by mucocutaneous lesions, a flulike syndrome, and generalized adenopathy. Hepatosplenomegaly may be present. The oral mucosa is the second most frequent site of luetic lesions; the genital areas are the most frequent. In the oral cavity, the most characteristic lesion is a whitish mucosal patch, normally located on the lips, tongue, or palate, which is extremely contagious. The differential diagnosis of this lesion may include oral squamous carcinoma, leukoplakia, candidosis, lichen planus, and hairy oral leukoplakia. Definitive diagnosis is based on clinical information and completed by laboratory examinations even the biopsy can help us. With the diagnosis of secondary syphilis treatment with penicillin G benzathine must be started. We present two cases of secondary syphilis with oral lesions only; the first one, a man with macule covered with a whitish membrane on palate mucosa and a

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

    Full Text Available São estudadas as várias questões gerais da Pelagra, nomeadamente os aspectos clínicos e etiopatogênicos. As formas clássicas se traduzem por manifestações intensificadas na época de maior insolação e evidenciadas por desordens da pele, do aparelho digestivo e sistema nervoso. Lembra o autor que, não obstante se deva ter em primeira conta esses aspectos do mal, na prática não se podem descuidar os oligossintomáticos, frustos e larvados. Com referência a tais formas, acredita ser de grande importância salientar os exemplares em que se não encontram sintomas cutâneos e configuram a "Pelagra sine Pelagra". A seguir, procura mostrar a freqüência dos aspectos neurológicos e psiquiátricos da condição e afirma que, se não se descrevem mais amiúde, é porque os médicos que se ocupam da Pelagra, descuidam de esmiuçar a existência de sinais e sintomas nervosos e mentais muito sutis que com freqüência passam despercebidos. Também recorda que os aspectos neurológicos da Pelagra não se encontram mais vezes, porque, via de regra, só se diagnostica a doença quando as lesões cutâneas são evidentes; de hábito deixam-se de lado os exemplares de "Pelagra Sine Pelagra", os de tradução clínica destituída de eritema ou outros fenômenos dermatológicos. Baseado na sua experiência, diz que as manifestações nervosas e mentais da Pelagra são em muito maior número do que é de supor-se. Para documentar essa afirmação, recorda a observação que tem feito em mais de uma oportunidade e os casos publicados pelos autores brasileiros; nem só os registados especialmente do ponto de vista neurológico mas, também, aqueles em que se não deu particular apreço a esse aspecto e em que a simples leitura das observações evidencia fenômenos neuro-psiquiátricos muito caraterísticos. Os quatro exemplares relatados no trabalho, foram colhidos do Serviço de Clínica Neurológica do Hospital Getúlio Vargas. Dois deles

    Full Text Available Desde el siglo XIX se conocen los efectos negativos del aumento de la presión intraabdominal, pero no se le prestó la debida atención a este trastorno hasta la última década del pasado siglo y la primera del actual. En este artículo exponemos las definiciones de los términos presión intrabdominal, hipertensión intrabdominal y síndrome compartimental abdominal, que fueron tomadas por consenso y aprobadas por la World Society of the Abdominal Compartment Syndrome. En nuestro medio, para el diagnóstico de la hipertensión intrabdominal y del síndrome compartimental abdominal se requiere medir la presión intrabdominal, secundariamente la presión de perfusión abdominal y se deben correlacionar estos datos con signos de deterioro clínico en el paciente. Las medidas terapéuticas médicas en relación con el síndrome compartimental abdominal son limitadas; cuando este es sintomático la descompresión abdominal es el tratamiento ya establecido. Enfatizamos en que el diagnóstico temprano de la hipertensión intrabdominal y del síndrome compartimental abdominal contribuyen a disminuir el desarrollo de un síndrome de disfunción múltiple de órganos y por tanto a reducir la mortalidad en estos pacientes. Con el objetivo de actualizar los conocimientos sobre hipertensión intrabdominal y síndrome compartimental abdominal, su diagnóstico y tratamiento, realizamos una minuciosa revisión actualizada de diversos artículos referentes al síndrome compartimental abdominal, tanto en el ámbito nacional como internacional.

    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 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.

  15. Micromanaging Abdominal Aortic Aneurysms

    2013-07-01

    Full Text Available The contribution of abdominal aortic aneurysm (AAA disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta. This work aims to develop novel diagnostic and therapeutic strategies to limit AAA expansion and, ultimately, rupture. Contributions from multiple research groups have uncovered a complex transcriptional and post-transcriptional regulatory milieu, which is believed to be essential for maintaining aortic vascular homeostasis. Recently, novel small noncoding RNAs, called microRNAs, have been identified as important transcriptional and post-transcriptional inhibitors of gene expression. MicroRNAs are thought to “fine tune” the translational output of their target messenger RNAs (mRNAs by promoting mRNA degradation or inhibiting translation. With the discovery that microRNAs act as powerful regulators in the context of a wide variety of diseases, it is only logical that microRNAs be thoroughly explored as potential therapeutic entities. This current review summarizes interesting findings regarding the intriguing roles and benefits of microRNA expression modulation during AAA initiation and propagation. These studies utilize disease-relevant murine models, as well as human tissue from patients undergoing surgical aortic aneurysm repair. Furthermore, we critically examine future therapeutic strategies with regard to their clinical and translational feasibility.

    To evaluate the changes in intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) during perioperative period in urgent abdominal surgery and to assess the relationship of these parameters with gas exchange and tissue perfusion. Twenty-four patients undergoing emergency abdominal surgery were enrolled into a prospective observational study. We recorded IAP APP, mean arterial pressure, arterial and venous blood gases after induction of anesthesia, at the end of surgery, and 6, 12, 48 and 72 h postoperatively. LAP was measured by nasogastric tube using CiMON monitor (Pulsion Medical Systems, Germany). In addition, we studied the relationship of IAP and APP with blood gases parameters. We observed perioperative increase of IAP (> 12 mm Hg) in 75% of enrolled patients, tendency to postoperative rise of IAP and transient increase of arterial lactate at 6 h after surgery. APP remained within normal values. We found positive correlation of APP with PaO2/FiO2 and ScvO2 at 72 hours after surgery. Transient perioperative increase of IAP was observed in 75% patients undergoing urgent abdominal surgery; however in parallel with intensive care the abdominal perfusion pressure remained within normal values. Abdominal perfusion is related with arterial oxygenation and central venous saturation.

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

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

  15. Common abdominal emergencies in children.

    Science.gov (United States)

    D'Agostino, James

    2002-02-01

    Because young children often present to EDs with abdominal complaints, emergency physicians must have a high index of suspicion for the common abdominal emergencies that have serious sequelae. At the same time, they must realize that less serious causes of abdominal symptoms (e.g., constipation or gastroenteritis) are also seen. A gentle yet thorough and complete history and physical examination are the most important diagnostic tools for the emergency physician. Repeated examinations and observation are useful tools. Physicians should listen carefully to parents and their children, respect their concerns, and honor their complaints. Ancillary tests are inconsistent in their value in assessing these complaints. Abdominal radiographs can be normal in children with intussusception and even malrotation and early volvulus. Unlike the classic symptoms seen in adults, young children can display only lethargy or poor feeding in cases of appendicitis or can appear happy and playful between paroxysmal bouts of intussusception. The emergency physician therefore, must maintain a high index of suspicion for serious pathology in pediatric patients with abdominal complaints. Eventually, all significant abdominal emergencies reveal their true nature, and if one can be patient with the child and repeat the examinations when the child is quiet, one will be rewarded with the correct diagnosis.

    Full Text Available Uncaria tomentosa is considered a medicinal plant used over centuries by the peruvian population as an alternative treatment for several diseases. Many microorganisms usually inhabit the human oral cavity and under certain conditions can become etiologic agents of diseases. The aim of the present study was to evaluate the antimicrobial activity of different concentrations of Uncaria tomentosa on different strains of microorganisms isolated from the human oral cavity. Micropulverized Uncaria tomentosa was tested in vitro to determine the minimum inhibitory concentration (MIC on selected microbial strains. The tested strains were oral clinical isolates of Streptococcus mutans, Staphylococcus spp., Candida albicans, Enterobacteriaceae and Pseudomonas aeruginosa. The tested concentrations of Uncaria tomentosa ranged from 0.25-5% in Müeller-Hinton agar. Three percent Uncaria tomentosa inhibited 8% of Enterobacteriaceae isolates, 52% of S. mutans and 96% of Staphylococcus spp. The tested concentrations did not present inhibitory effect on P. aeruginosa and C. albicans. It could be concluded that micropulverized Uncaria tomentosa presented antimicrobial activity on Enterobacteriaceae, S. mutans and Staphylococcus spp. isolates.Uncaria tomentosa é uma planta medicinal usada por vários séculos pela população peruana como alternativa de tratamento para diversas doenças.

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

    Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths. We report a case of a patient with 27 years old, and diagnosis of 25.2 weeks of pregnancy, prior placenta and anhidramnios, referred due to difficult in uterine contour delimitation, easy palpation of fetal parts, cephalic pole in left hypochondrious and presence of mass in hypogastria, no delimitations, pain with mobilization, no transvaginal bleed and fetal movements. Interruption of pregnancy is decided by virtue of severe oligohidramnios, retardation in fetal intrabdominal growth, and recurrent maternal abdominal pain. Surgical intervention was carried out for resolution of the obstetrical event, in which was found ectopic abdominal pregnancy with bed placental in right uterine horn that corresponded to a pregnancy of 30 weeks of gestation. Abdominal pregnancy is still a challenge for obstetrics due to its diagnosis and treatment. Early diagnosis is oriented to prevent an intrabdominal hemorrhage that is the main maternal cause of mortality.

    2015-01-01

    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

    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.

    Abdominal injuries are rare in sports, but when they do occur it is important that the physician recognize the warning signs of potentially life-threatening injury to the liver, spleen, or hollow abdominal viscera. Though the sports medicine physician may not always provide definitive treatment of many of these conditions, he or she should be familiar with the preferred diagnostic modalities and latest treatment options. This information is not only essential to appropriately participate in treatment decisions, but is also important in order to make return-to-play determinations.

    The authors report the case of a 93-year old woman referred to the emergency department and presenting with an intestinal obstruction. Abdominal CT reveals a biliary ileus caused by the migration and the impaction of a 3 cm gallstone in the small bowel. Surgical treatment by enterolithotomy was successful. In over 90% of cases, gallstone ileus is a complication of cholelithiasis and accounts for 25% of intestinal obstruction in patients over 65 years. To reduce morbidity and mortality, early diagnosis and prompt treatment are essential. Abdominal CT-scan is the gold standard technique.

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

    Full Text Available Abdominal actinomycosis is a rare infectious disease, caused by gram positive anaerobic bacteria, that may appear as an abdominal mass and/or abscess (Wagenlehner et al. 2003. This paper presents an unusual case of a hemodynamically stable 80-year-old man who presented to the emergency department with 4 weeks of worsening abdominal pain and swelling. He also complains of a 20-bound weight loss in 2 months. A large tender palpable mass in the right upper quadrant was noted on physical exam. Laboratory studies showed a normal white blood cell count, slightly decreased hemoglobin and hematocrit, and mildly elevated total bilirubin and alkaline phosphatase. A CT with contrast was done and showed a liver mass. Radiology and general surgery suspected malignancy and recommended CT guided biopsy. The sample revealed abundant neutrophils and gram positive rods. Cytology was negative for malignancy and cultures eventually grew actinomyces. High dose IV penicillin therapy was given for 4 weeks and with appropriate response transitioned to oral antibiotic for 9 months with complete resolution of symptoms.

This paper presents an unusual case of a hemodynamically stable 80-year-old man who presented to the emergency department with 4 weeks of worsening abdominal pain and swelling. He also complains of a 20-bound weight loss in 2 months. A large tender palpable mass in the right upper quadrant was noted on physical exam. Laboratory studies showed a normal white blood cell count, slightly decreased hemoglobin and hematocrit, and mildly elevated total bilirubin and alkaline phosphatase. A CT with contrast was done and showed a liver mass. Radiology and general surgery suspected malignancy and recommended CT guided biopsy. The sample revealed abundant neutrophils and gram positive rods. Cytology was negative for malignancy and cultures eventually grew actinomyces. High dose IV penicillin therapy was given for 4 weeks and with appropriate response transitioned to oral antibiotic for 9 months with complete resolution of symptoms. PMID:28299215

    Full Text Available Aunque se han descrito numerosos materiales para rellenar una cavidad ósea, el mejor material sigue siendo el hueso autólogo corticoesponjoso o particulado, que puede formar hueso nuevo por mecanismos de osteogénesis, osteinducción y osteoconducción. El cirujano oral y maxilofacial debe conocer las propiedades biológicas y las características fundamentales de los materiales autólogos, las diferentes técnicas de obtención y sus aplicaciones clínicas. Como zonas donantes se emplean preferentemente las intraorales, el filtro de hueso y los raspadores para pequeños defectos, y el hueso ilíaco, tibia o calota cuando se requiere más cantidad. No existen estudios concluyentes respecto a la asociación de injertos óseos con membranas. La combinación de injertos autólogos con otros materiales de relleno, ha desembocado en múltiples estudios, sin que se puedan establecer conclusiones definitivas por el momento. El hueso autólogo es de elección para el relleno de cavidades óseas, ya que es útil para dar solución a variadas situaciones clínicas de forma simple, rápida y segura.Although a large number of materials have been described for augmenting bone cavities, the best material is still autologous cortical-cancellous bone or bone chip, which can form new bone through osteogenesis, osteoinduction and osteoconduct ion mechanisms. The oral and maxillofacial surgeon needs to be familiar with the biological properties and the fundamental characteristics of autologous material, the different techniques for obtaining it and its clinical application. Donor sites should preferably be intraoral. Bone filters and scrapers should be used for small defects, and the iliac, tibial or calvaria bones [should be used] when more quantity is required. There are no conclusive studies with regard to combining bone grafts with membranes. The combination of autologous grafts with other augmentation material has led to multiple studies, although

Foi realizado estudo retrospectivo dos laudos de necropsia do Laboratório de Patologia Veterinária da Universidade de Brasília (LPV-UnB nos anos de 2003 a 2014 para verificar a ocorrência das doenças que acometeram a cavidade nasal de pequenos ruminantes. Foram analisados 463 protocolos de ovinos e 75 de caprinos totalizando 538 casos. Seis ovinos (6/463 1,29% foram necropsiados com rinite granulomatosa micótica ou oomicótica e 22 animais do estudo (22/538; 4,08% tiveram o diagnóstico de oestrose, sendo 86,36% ovinos e 13,64% caprinos. As rinites piogranulomatosas em ovinos ocorreram em áreas alagadas, com abundante material vegetal em decomposição. Os ovinos com pitiose rinofacial apresentaram como principais alterações aumento de volume na região nasal devido a extensas lesões granulomatosas associadas a necrose tecidual, caracterizadas por inúmeros macrófagos e polimorfonucleares circundando centros necróticos contendo o agente envolto por reação de Splendore-Hoeppli. Os ovinos com conidiobolomicose exibiram extensas áreas de necrose e inflamação piogranulomatosa, associadas à presença de hifas fúngicas na nasofaringe e também na região peribulbar e exoftalmia. A maioria dos animais com oestrose não apresentou alterações clínico-patológicas significativas, apesar de serem encontradas larvas principalmente nos seios e conchas nasais, traqueia e seio paranasal. A importância dessas enfermidades ainda é pouco conhecida na região, sendo de grande relevância que as condições clínico-patológicas e epidemiológicas sejam elucidadas para o diagnóstico, o controle e a prevenção, para evitar a expansão e prejuízos para os rebanhos.

    Three different regimens of antibiotic treatment have been employed in order to evaluate their efficacy as a profilaxis for abdominal hysterectomy. Two short term administrations (Cephtriaxone and Cephamandole plus Tobramycine) and a conventional full dose treatment (Cephazoline) have been compared over a group of homogeneous patients. No significant differences, except a reduction in postoperative time spent in hospital, have been found among the groups. A reduction in urinary tract infection has also been reported with a single-dose antibiotic prophylaxis.

    Full Text Available Staphylococcus spp are not usually isolated from the oral cavity, and when this occurs, they are considered to belong to the transitory microbiota. Individuals with periodontal disease represent possible reservoirs of these opportunistic bacteria in the oral cavity. The use of antibiotics for treatment of periodontal disease or other infections may predispose to the increase of the number of Staphylococcus spp. in the oral cavity. These microorganisms easily become resistant to antibiotics, and may result in superinfection. The purpose of this study was to evaluate the presence of Staphylococcus spp. in the oral cavity and in periodontal pockets of patients with chronic periodontitis, identify the isolates and verify the relationship between the presence of Staphylococcus spp. in the oral cavity and presence of periodontal pockets. The study included eighty-eight patients, 25-60 years of age, with chronic periodontitis, and at least two sites with probing depth > 5 mm. Individual data examination was assessed. Then, samples were colleted from the periodontal pocket with the aid of paper tips and from the oral cavity through mouth rinses. Out of the total of patients, 37.50% presented Staphylococcus spp. in the periodontal pocket and 61.36% in the oral cavity, 27.27% presented the bacteria in both sites. S. epidermidis was the most prevalent specie in the periodontal pocket (15.9% and oral cavity (27.27%. The occurrence of higher proportions of nonresident's microorganisms in subgingival samples and oral sites may represent significant problem in causing and maintaining periodontal infections.Staphylococcus spp. não são usualmente isolados a partir da cavidade bucal.

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

  20. Appendicitis following blunt abdominal trauma.

    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.

    2013-08-31

    Laparoscopic cholecystectomy (key-hole removal of the gallbladder) is now the most often used method for treatment of symptomatic gallstones. Several cardiopulmonary changes (decreased cardiac output, pulmonary compliance, and increased peak airway pressure) occur during pneumoperitoneum, which is now introduced to allow laparoscopic cholecystectomy. These cardiopulmonary changes may not be tolerated in individuals with poor cardiopulmonary reserve. To assess the benefits and harms of abdominal wall lift compared to pneumoperitoneum in patients undergoing laparoscopic cholecystectomy. We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2013. We included all randomised clinical trials comparing abdominal wall lift (with or without pneumoperitoneum) versus pneumoperitoneum. We calculated the risk ratio (RR), rate ratio (RaR), or mean difference (MD) with 95% confidence intervals (CI) based on intention-to-treat analysis with both the fixed-effect and the random-effects models using the Review Manager (RevMan) software. For abdominal wall lift with pneumoperitoneum versus pneumoperitoneum, a total of 130 participants (all with low anaesthetic risk) scheduled for elective laparoscopic cholecystectomy were randomised in five trials to abdominal wall lift with pneumoperitoneum (n = 53) versus pneumoperitoneum only (n = 52). One trial which included 25 people did not state the number of participants in each group. All five trials had a high risk of bias. There was no mortality or conversion to open cholecystectomy in any of the participants in the trials that reported these outcomes. There was no significant difference in the rate of serious adverse events between the two groups (two trials; 2/29 events (0.069 events per person) versus 2/29 events (0.069 events per person); rate ratio 1.00; 95% CI 0

    Full Text Available The incidence of intraperitoneal adhesion after abdominal surgery was studied. Peritoneoscopy was performed in 933 patients with liver diseases over the 6 year 5 month period from March 1974 to July 1980. Of the patients, 352 (37.7% had undergone an abdominal operation, and intraperitoneal adhesion was detected in 205 (58.2% of these patients. The liver was not observable in 5 out of 61 patients with adhesions after upper abdominal operations. Whereas, the liver was clearly observable in patients with lower abdominal operations in spite of adhesions. Out of the 581 patients without any abdominal operations, 30 patients (5.2% had adhesions in the abdominal cavity, and 6 of them had extensive adhesions that partially obscured the observation of liver surface. In all patients, peritoneoscopy was performed without complications by avoiding the surgical scar for puncture sites and ensuring a free air lumen before trocar puncture.

    2016-08-01

    With an aging population, emergency department clinicians can expect an increase in geriatric patients presenting with abdominal pain. Compared with younger patients, this patient population is less likely to present with classic symptoms, physical examination findings, and laboratory values of abdominal disease. However, the morbidity and mortality associated with elderly patients presenting with abdominal pathologic conditions are significant. For this reason, the clinician must be familiar with some subtle and not so subtle differences when caring for the geriatric patient with abdominal pain to ensure timely diagnosis and appropriate treatment.

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

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

    The role of magnetic resonance angiography (MRA) in the evaluation of vascular involvement was studied in 55 patients with abdominal neoplasms. A 2-D time-of-flight (TOF) technique was used in all patients. All patients underwent CT and MR examinations before MRA. Also, MR angiograms were compared with digital subtraction angiography in 22 cases, with Doppler US in 13 cases, and with surgical findings in 20 cases. In all patients with liver neoplasms (n=29) MRA demonstrated the absence of flow in the infiltrated segments. Pericapsular neovascularization was observed in 12 patients. Portal vein involvement was correctly detected in 27 patients. In all cases MRA demonstrated in relationship between the tumor and venous structures. Portosystemic shunts were visualized in 20 of 21 patients with portal hypertension. Vena cava thrombosis (3 cases), compression (5 cases), and displacement (2 cases) were correctly demonstrated. In renal (n=6) and adrenal gland (n=3) tumors renal vein compression was correctly detected in 2 cases, displacement in 1 case, and thrombosis in 3 cases, with only 1 false-positive finding. In 7 patients with pancreatic tumors MRA demonstrated splenic vein thrombosis in 2 cases and compression in 2 cases, with one false-positive finding. Our results indicate that MRA provides precise information regarding venous vascular involvement in abdominal neoplasms, but preoperative arterial mapping is still problematic. (orig.)

En primer lugar, se alude a las cosas mismas como el punto de partida del filosofar de esta autora. En segundo lugar, se considera el aspecto que constituye uno de los aportes fundamentales del método fenomenológico y que es claramente reconocible en nuestra autora, a saber, el haber puesto de manifiesto la imposibilidad de hacer filosofía primera sin tomar en cuenta la vida consciente ante la que todas las cosas se abren. En tercer lugar, se remite a la individualidad de la persona como un aspecto de la antropología de Stein especialmente relevante. Al final del análisis de cada uno de estos tres aspectos metodológicos se intenta mostrar en qué sentido éstos pueden ser de relevancia para emprender el camino hacia la pregunta por la mujer.This paper addresses three fundamental aspects of Edith Stein's philosophical method. Firstly, it looks at issues such as the author's starting point of philosophizing. Secondly, it considers the aspect, which constitutes one of the fundamental contributions of the phenomenological method and is clearly recognizable in our author, such as having highlighted that it is impossible to carry out first philosophy without taking into account conscious life, before which all things are opened. Thirdly it looks at the individuality of the person as an especially relevant aspect of Stein's anthropology After analyzing each of these methodological aspects, this paper attempts to show how they may be relevant in laying out the path towards the question of the woman.

A operação foi realizada principalmente sob monitoramento videolaparoscópico de 10 mm pelo portal umbilical e por meio de três portais de 2 mm (epigástrico, hipocôndrio direito e flanco direito. Utilizou-se o videolaparoscópio de 2 mm pelo portal epigástrico quando se procedeu às ligaduras císticas, ocasião em que o laparoscópio de 10 mm umbilical era substituído pelo aplicador de clipes de 10 mm. Da mesma forma, a vesícula foi retirada da cavidade abdominal pelo portal umbilical sob monitoramento videolaparoscópico de 1,7 mm epigástrico. A maioria dos casos operados (89,2% não apresentava espessamento da parede vesicular. O tempo cirúrgico médio do procedimento foi de 92 ± 21 min e o de internação foi de 16 h. A principal intercorrência operatória foi a perfuração da vesícula biliar (41%, atribuída à curva de aprendizado no método por que passa a equipe. Vômitos foram a principal complicação pós-operatória (51,8%, não tendo havido infecção de ferida operatória. Oitenta e dois por cento dos casos puderam ser terminados pelo método agulhascópico puro, enquanto em 6% e 3,6%, respectivamente, houve necessidade de trocar um dos portais de 2 mm por um de 5 ou de 10 mm e de converter o procedimento para videolaparoscopia usual. Em 6% dos casos, por problemas de imagem com o microlaparoscópio, realizou-se o procedimento

    Full Text Available Descreve-se um órgão glandular, encontrado na fêmea de Arilus carinatus, de um tipo ainda desocnhecido em insetos. Localiza-se, em forma de um saco membranoso, nos dois lados da linha ventral, entre os 8º e 9º segmentos abdominais. O órgão é expulso por um aumento da pressão interna da cavidade abdominal e volta ao estado de repouso, no interior do corpo, por meio de contração muscular. A vesícula retal volumosa forma, em direção distal, um amplo divertículo, do qual partem dois "tubos retais" que penetram nas vesículas membranosas, tendo na superfície destas uma abertura em forma de fenda. A hipoderme do divertículo, bem como a de uma região da vesícula retal e da parte basal dos tubos retais é glandular. A secreção possui um cheiro intenso e ardido que lembra o gás de acetileno. Trata-se, provàvelmente, de uma glândula repugnatória. Não se sabe nada sôbra a ocorrência do aparelho no macho e em outras espécies de Reduviídeos.

    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 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.

  8. Pulmonary complications of abdominal wall defects.

    Science.gov (United States)

    Panitch, Howard B

    2015-01-01

    The abdominal wall is an integral component of the chest wall. Defects in the ventral abdominal wall alter respiratory mechanics and can impair diaphragm function. Congenital abdominal wall defects also are associated with abnormalities in lung growth and development that lead to pulmonary hypoplasia, pulmonary hypertension, and alterations in thoracic cage formation. Although infants with ventral abdominal wall defects can experience life-threatening pulmonary complications, older children typically experience a more benign respiratory course. Studies of lung and chest wall function in older children and adolescents with congenital abdominal wall defects are few; such investigations could provide strategies for improved respiratory performance, avoidance of respiratory morbidity, and enhanced exercise ability for these children.

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

    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....

    2003-12-01

    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.

    2014-11-01

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

    Full Text Available CONTEXTO: A correção das hérnias volumosas e dos grandes defeitos da parede abdominal constitui grande desafio da prática cirúrgica, em virtude das dificuldades técnicas e do alto índice de complicações respiratórias e cardiovasculares. OBJETIVOS: Apresentar experiência com a indução do pneumoperitônio progressivo no pré-operatório do tratamento cirúrgico das hérnias volumosas da parede abdominal. MÉTODOS: Estudo retrospectivo de seis pacientes que apresentavam hérnias volumosas da parede abdominal, e que foram operados após a instalação de um pneumoperitônio. O procedimento foi realizado através da colocação de um cateter na cavidade abdominal, na altura do hipocôndrio esquerdo, com insuflação de ar ambiente por período de 10 a 15 dias. RESULTADOS: Dos seis pacientes operados, quatro eram do sexo feminino e dois do masculino. A idade mínima era de 40 e a máxima de 62 anos. A duração da hérnia variou de 5 a 40 anos. Quatro pacientes tinham hérnia incisional, um umbilical e outro inguinal. O tempo médio de pneumoperitônio foi de 11,6 dias. Não houve complicações relacionadas à instalação e manutenção do pneumoperitônio. Todas as hérnias foram corrigidas sem dificuldades técnicas. Utilizou-se a técnica de Lichtenstein para a correção da hérnia inguinal, a transposição peritônio-aponeurótica para uma das hérnias incisionais, sendo as demais corrigidas com uso de tela de polipropileno. Um óbito e uma infecção de parede foram observados no pós-operatório dessas cirurgias. Não houve recidivas registradas até o momento, num período de seguimento de 4 a 36 meses. CONCLUSÃO: O pneumoperitônio progressivo pré-operatório é um procedimento seguro e de fácil execução, pois facilita o procedimento cirúrgico e diminui as complicações respiratórias e cardiovasculares no pós-operatório. É indicado para doentes com hérnias que perderam domicílio na cavidade abdominal

In the single insult model, Sprague-Dawley male-rats are anesthetized, invasively monitored (central venous pressure and mean arterial pressure, and mechanically ventilated during intraperitoneal injection of air to provoke the abdominal compartment syndrome (25 mmHg for 60 minutes. In the two insult model, Sprague-Dawley male-rats are anesthetized, invasively monitored (mean arterial pressure and bled to a mean arterial pressure of 30 mmHg for 45 minutes. Fluid resuscitation is accomplished by infusing 0.9% sodium chloride solution (0.9% NaCl 33.2 ml/kg plus 75% of shed blood volume. During this phase a laparotomy is performed. Two hours after the beginning of the hemorrhagic shock phase the animals are anesthetized, intubated (orotracheal, mechanically ventilated (mean arterial pressure, and the intra-abdominal pressure is increased to 25 mmHg for 60 minutes, as a second insult. A 0.9% NaCl solution is infused during this phase (45 ml/kg/h.

    2014-01-01

    Patients in the intensive care unit (ICU) are at risk of developing of intra abdominal hypertension (IAH) and abdominal compartment syndrome (ACS). Aim: This review seeks to define IAH and ACS, identify the aetiology and presentation of IAH and ACS, identify IAP measurement techniques, identify current management and discuss the implications of IAH and ACS for nursing practice. A search of the electronic databases was supervised by a health librarian. The electronic data bases Cumulative Index of Nursing and Allied Health Literature (CINAHL); Medline, EMBASE, and the World Wide Web was undertaken from 1996- January 2011 using MeSH and key words which included but not limited to: abdominal compartment syndrome, intra -abdominal hypertension, intra-abdominal pressure in adult populations met the search criteria and were reviewed by three authors using a critical appraisal tool. Data derived from the retrieved material are discussed under the following themes: (1) etiology of intra-abdominal hypertension; (2) strategies for measuring intra-abdominal pressure (3) the manifestation of abdominal compartment syndrome; and (4) the importance of nursing assessment, observation and interventions. Intra-abdominal pressure (IAP) and abdominal compartment syndrome (ACS) have the potential to alter organ perfusion and compromise organ function. PMID:24499574

    Full Text Available RESUMO: Estudos vêm mostrando uma possível associação das doenças bucais no período gestacional com o nascimento pré-termo (NPT e o baixo peso ao nascer (BPN. Esses desfechos perinatais parecem se associar com defeitos de desenvolvimento do esmalte (DDE na dentição decídua, que, por sua vez, parecem predispor ao desenvolvimento futuro de lesões de cárie nas crianças. Assim, é relevante a inclusão de variáveis de saúde bucal do binômio mãe/filho nos estudos de coorte para a compreensão de como esses fatores se associam. Os objetivos deste estudo são: 1 verificar se existe associação entre doenças da cavidade bucal da gestante e o NPT; 2 testar a hipótese de associação entre desfechos perinatais e defeitos de esmalte/cárie dentária nas crianças; 3 analisar se existem associações entre desfechos perinatais e distúrbios de erupção dentária nas crianças; 4 construir modelos teóricos para estudo das iniquidades sociais como fator comum entre os desfechos perinatais e condições bucais. Utilizou-se abordagem integrada e colaborativa entre duas cidades brasileiras com condições socioeconômicas contrastantes: São Luís, MA; e Ribeirão Preto, SP - estudo BRISA (Brazilian Birth Cohort Studies, Ribeirão Preto-São Luís . Duas coortes foram avaliadas: uma iniciada ao nascimento, representativa da população de nascidos vivos; e outra iniciada no pré-natal. Os participantes foram reavaliados a partir do início do segundo ano de vida. Espera-se que estas coortes contribuam para fomentar o desenvolvimento e consolidação de pesquisas de seguimento, de base populacional, no Brasil.

    Full Text Available El carcinoma fusocelular es una variedad maligna y poco frecuente del carcinoma de células escamosas. Es una tumoración constituida por una doble proliferación celular: una sarcomatosa de células fusocelulares y otra carcinomatosa de células epiteliales. Aunque puede afectar a cualquier parte del organismo, es más frecuente encontrarla en vías aerodigestivas superiores. Afecta con mayor frecuencia a varones entre la 6ª y 7ª décadas de la vida. Tiene un comportamiento agresivo con tendencia a la recurrencia. El alcohol y tabaco han sido identificados como los factores de riesgo más importantes. Su diagnóstico histológico es complicado y muchas veces es necesario recurrir a técnicas de inmunohistoquímica y al uso del microscopio electrónico. En la actualidad, se le atribuye un origen epitelial. El objetivo de este trabajo es presentar una revisión de 9 casos de carcinoma fusocelular localizados en cavidad oral recogidos en nuestro servicio entre los años 1985 a 2004, describiendo su comportamiento clínico y tratando de comprender la patogenia de esta controvertida estirpe tumoral.Spindle cell carcinoma is a malignant and rare variant of squamous cell carcinoma. The histological pattern is composed of a double cell proliferation: a sarcomatous component made up of spindle-shaped cells and a carcinomatous component made up of epithelial cells. Nearly all the anatomy of the body can be affected by these tumors although the most common location is the upper aerodigestive tract. With regard to sex distribution, it is more frequent in males than in females in their sixth and seventh decades of life. Its behavior is aggressive and it tends to recur after treatment. The most important risk factors are alcohol and tobacco. The histological diagnosis is complicated, so immunohistochemical techniques and the use of electron microscopy are usually necessary. Nowadays, its epithelial origin is accepted. The aim of this article is to report a

    Full Text Available São discutidos os aspectos relativos ao diagnóstico e tratamento dos hemangiomas cavernosos do crânio. Os dados obtidos em 26 casos, são apresentados, sendo salientado que a localização dos hemangiomas foi maior na região frontal, sendo mais atingido o sexo masculino. Os outros aspectos são coincidentes com os demais autores. A problemática desses tumores, principalmente a sua demonstração radiológica e o seu tratamento, são ressaltados, chegando-se à conclusão final de que o melhor meio de demonstração radiológica é a punção para contrastação direta do tumor. O tratamento de escolha é o cirúrgico, sendo a extirpação em bloco preferida nos casos de comprometimento ósseo importante, sendo a intervenção direta com dissecção e excisão reservada para as localizações nos tecidos moles ou com mínima participação óssea.

    Full Text Available Endometriosis is an estrogen-dependent inflammatory disease, common in young women, characterized by the presence of endometrial tissue outside the uterine cavity. This ectopic endometrial tissue is most commonly found in the ovaries, peritoneum, uterosacral ligaments and rectovaginal cul-de-sac, with extremely rare involvement of the appendix. The main symptom is chronic abdominal pain, and the diagnosis is often made later, after the result of the histopathological examination. This study reports a 34-year-old patient complaining of chronic pelvic pain refractory to medical treatment, having undergone diagnostic laparotomy. During the surgery, we observed the presence of endometrioma fixed to the uterine wall, and the appendix was enlarged, but without evidence of inflammation. Endometrioma resection and appendectomy were performed, with good postoperative recovery. The anatomopathological exam showed endometriosis in the cecal appendix.Endometriose é uma doença inflamatória estrogênio-dependente frequente em mulheres jovens, caracterizada pela presença de tecido endometrial fora da cavidade uterina. Esse tecido ectópico de endométrio é mais comumente encontrado nos ovários, peritônio, ligamentos uterossacros e fundo de saco retovaginal, sendo o acometimento do apêndice cecal extremamente raro. O quadro clínico predominante é o de dor abdominal crônica, sendo muitas vezes o diagnóstico feito posteriormente, após o resultado do anatomopatológico. Relatamos o caso de uma paciente de 34 anos com queixa de dor pélvica crônica, refratária ao tratamento clínico, tendo sido submetida à laparotomia exploradora diagnóstica. Durante o ato cirúrgico, observamos a presença de endometrioma fixo à parede uterina, bem como apêndice cecal aumentado de volume, porém sem evidência de sinais flogísticos. Procedeu-se à ressecção do endometrioma e apendicectomia, com boa evolução pós-operatória. O resultado do exame

    1993-01-01

    Approximately 10 per cent of abdominal aneurysms have an excessively thick wall that sometimes involve duodenum, cava or colon by an inflammatory process. Between February 1986 and December 1992, 147 patients with abdominal aortic aneurysm (AAA) were treated surgically and in 13 (8.8%) the aneurysms were found to be inflammatory. Their mean age was 67.3 years (70.1 years in non inflammatory group) and all were symptomatics initially (abdominal pain in 53%, rupture in 23%, mass in 15%). The operative mortality for elective resection was 37% in patients with inflammatory abdominal aortic aneurysms (IAAA) decreasing to 9% in the AAA group without inflammatory involvement. We conclude that surgery is indicated in these patients to prevent rupture and to hasten the subsidense of inflammatory process ever with postoperative morbi-mortality increased.

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

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

    Science.gov (United States)

    Stagnitti, Franco

    2009-01-01

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

    In order to evaluate the usefulness of MR imaging in the diagnosis of abdominal mass in children, we compared MR imaging with CT in 33 children who had undergone both examinations. Although MR imaging was less specific to calcification, gas and fat, it was more specific to hematoma and clarified the extension of tumors more precisely than CT. MRI seems to be a promising diagnostic modality for pediatric abdominal masses. (author).

  20. A focus on intra-abdominal infections

    Directory of Open Access Journals (Sweden)

    Sartelli Massimo

    2010-03-01

    Full Text Available Abstract Complicated intra-abdominal infections are an important cause of morbidity and are frequently associated with poor prognosis, particularly in higher risk patients. Well defined evidence-based recommendations for intra-abdominal infections treatment are partially lacking because of the limited number of randomized-controlled trials. Factors consistently associated with poor outcomes in patients with intra-abdominal infections include increased illness severity, failed source control, inadequate empiric antimicrobial therapy and healthcare-acquired infection. Early prognostic evaluation of complicated intra-abdominal infections is important to select high-risk patients for more aggressive therapeutic procedures. The cornerstones in the management of complicated intra-abdominal infections are both source control and antibiotic therapy. The timing and the adequacy of source control are the most important issues in the management of intra-abdominal infections, because inadequate and late control of septic source may have a negative effect on the outcomes. Recent advances in interventional and more aggressive techniques could significantly decrease the morbidity and mortality of physiologically severe complicated intra-abdominal infections, even if these are still being debated and are yet not validated by limited prospective trials. Empiric antimicrobial therapy is nevertheless important in the overall management of intra-abdominal infections. Inappropriate antibiotic therapy may result in poor patient outcomes and in the appearance of bacterial resistance. Antimicrobial management is generally standardised and many regimens, either with monotherapy or combination therapy, have proven their efficacy. Routine coverage especially against Enterococci and candida spp is not always recommended, but can be useful in particular clinical conditions. A de escalation approach may be recommended in patients with specific risk factors for multidrug

    There are many medical causes of abdominal pain; abdominal epilepsy is one of the rarer causes. It is a form of temporal lobe epilepsy presenting with abdominal aura. Temporal lobe epilepsy is often idiopathic, however it may be associated with mesial temporal lobe sclerosis, dysembryoplastic neuroepithelial tumors and other benign tumors, arterio-venous malformations, gliomas, neuronal migration defects or gliotic damage as a result of encephalitis. When associated with anatomical abnormality, abdominal epilepsy is difficult to control with medication alone. In such cases, appropriate neurosurgery can provide a cure or, at least, make this condition easier to treat with medication. Once all known intra-abdominal causes have been ruled out, many cases of abdominal pain are dubbed as functional. If clinicians are not aware of abdominal epilepsy, this diagnosis is easily missed, resulting in inappropriate treatment. We present a case report of a middle aged woman presenting with abdominal pain and episodes of unconsciousness. On evaluation she was found to have an intra-abdominal foreign body (needle). Nevertheless, the presence of this entity was insufficient to explain her episodes of unconsciousness. On detailed analysis of her medical history and after appropriate investigations, she was diagnosed with temporal lobe epilepsy which was treated with appropriate medications, and which resulted in her pain being relieved.

  5. Hérnia traumática da parede abdominal Traumatic abdominal hernia

    Full Text Available A rare case of blunt traumatic abdominal hernia is presented in which jejunal loops herniated through the abdominal wall. The patient had a serious motor vehicle accident seven years ago, while wearing the seat belt. He developed a traumatic hernia in the anterior lateral abdominal wall, which was operated, and relapsed after some months. The patient was reoperated and we observed the unattachment of the anterior lateral abdominal musculature from the ilium crest. After the hernial sac treatment, the defect was solved with the use of a polypropylene mesh. The postoperative evolution was good and four months later there were no signs of recurrence. Traumatic abdominal hernia remains a rare clinical entity, despite the increase in blunt abdominal trauma. Traumatic abdominal wall hernia falls into two general categories: small lower quadrant abdominal defects, typically the result of blunt trauma with bicycle handlebars, and larger abdominal wall defects related to motor vehicle accidents. The diagnosis may be often established by the physical examination alone. Conventional radiology and computerized tomography usefulness have been proved. In the vast majority of cases, early repair is recommended. The appropriate treatment is the reduction of the herniated bowel into the abdomen, the debridment of nonviable tissues, and a primary tension free closure of the detect.

    Abdominal fat is associated with metabolic disorders, leading to cardiovascular risk factors and numerous diseases. This study aimed to analyze the effect of plaster body wrap in combination with aerobic exercise on abdominal fat. Nineteen female volunteers were randomly divided into intervention group (IG; n = 10) performing aerobic exercise with plaster body wrap, and control group (CG; n = 9) performing only exercise. Subcutaneous and visceral fat were measured using ultrasound; subcutaneous fat was also estimated on analysis of skinfolds and abdominal perimeters. At the end of the 10-sessions protocol, the IG demonstrated a significant decrease (p ≤ 0.05) in subcutaneous fat at the left anterior superior iliac spine (ASIS) level and in iliac crest perimeter measurements. A large intervention effect size strength (0.80) was found in subcutaneous fat below the navel and a moderate effect size strength on the vertical abdominal skinfold (0.62) and the perimeter of the most prominent abdominal point (0.57). Comparing the initial and final data of each group, the IG showed a significant decrease in numerous variables including visceral and subcutaneous fat above and below the navel measured by ultrasound (p ≤ 0.05). Plaster body wrap in combination with aerobic exercise seems to be effective for abdominal fat reduction.

    Full Text Available Alguns estudos evidenciam que a adoção das International Financial Reporting Standards (IFRS proporcionou melhorias na qualidade das informações contábeis. Mas, o conjunto de Procedimentos descritos nas IFRSs é fortemente afetado pelo julgamento profissional dos contadores. O mesmo fato ocorre com o auditor, que deve avaliar se a aplicação das normas resulta em fair presentation. Esse julgamento dependerá da interpretação do auditor sobre o nível de probabilidade associada a determinadas expressões presentes no texto das normas contábeis. Alguns autores evidenciam que existem diferenças significativas na interpretação das expressões verbais de probabilidade entre os auditores e que aspectos comportamentais estão influenciando a emissão do parecer de auditoria. Diante desse cenário, o objetivo deste estudo foi investigar como se comportam os auditores no julgamento de situações subjetivas, inseridos em um cenário pessimista ou otimista, no momento da avaliação dos critérios de reconhecimento e/ou mensuração, quando da execução dos trabalhos da auditoria. A amostra desta pesquisa é composta por 258 auditores independentes com registro de responsáveis técnicos junto à Comissão de Valores Mobiliários (CVM. Os resultados obtidos, por intermédio da análise das respostas dos auditores para situações subjetivas, sugerem que o julgamento do auditor em situações de subjetividade é influenciado por aspectos comportamentais, sendo que eles podem apresentar opiniões distintas em seus relatórios.

    Full Text Available RACIONAL: Atribui-se aos abscessos intra-abdominais e às aderências peritoniais a função de isolar os processos sépticos e proteger o organismo da bacteremia. Por outro lado, esses fenômenos também dificultam o afluxo de fatores imunitários e antibióticos para a região infectada. OBJETIVO: Avaliar o efeito da prevenção de abscessos na sobrevida após peritonite bacteriana. MÉTODOS: Foram estudados 30 ratos Wistar machos que receberam solução de fezes a 50% intra-abdominal e que foram distribuídos em três grupos (n = 10. Grupo 1: controle (solução de fezes; grupo 2: solução de fezes mais solução salina a 0,9%; grupo 3: solução de fezes mais carboximetilcelulose a 1%, para inibir a formação de aderências. Os três grupos foram divididos em dois subgrupos (n = 5: subgrupo A: nova laparotomia, após 4 dias, para inspeção da cavidade abdominal; e subgrupo B: acompanhamento durante 30 dias para avaliação da mortalidade e da causa de morte. A análise estatística utilizou o teste exato de Fisher. RESULTADOS: O acréscimo de solução salina a 0,9% não aumentou a mortalidade do grupo. Entretanto, no grupo em que se acrescentou a solução de carboximetilcelulose, houve menor formação de abscessos, que também foram mais tênues e a mortalidade aumentou em relação ao grupo controle. CONCLUSÃO: A inibição na formação de aderências peritoniais e de abscessos acompanha-se de maior mortalidade decorrente do processo séptico intra-abdominal generalizado.

    Intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) have shown clinical relevance in monitoring critically ill human beings submitted to abdominal surgery. Only a few studies have been performed in veterinary medicine. The aim of this study was to assess how pregnancy and abdominal surgery may affect IAP and APP in healthy cats. For this purpose, pregnant (n=10) and non-pregnant (n=11) queens undergoing elective spaying, and tomcats (n=20, used as controls) presented for neutering by scrotal orchidectomy were included in the study. IAP, mean arterial blood pressure (MAP), APP, heart rate and rectal temperature (RT) were determined before, immediately after, and four hours after surgery. IAP increased significantly immediately after abdominal surgery in both female groups when compared with baseline (PPregnancy did not seem to affect IAP in this population of cats, possibly due to subjects being in early stages of pregnancy.

    Full Text Available A neurocisticercose pode provocar hipertensão intracraniana por bloqueio inflamatório das cisternas basais ou pela formação de lesões expansivas no parenquima cerebral e nas cavidades ventriculares. Neste último caso o quadro clínico é muito semelhante ao das neoplasias e só após a intervenção cirúrgica é possível o diagnóstico etiológico. Apresentamos 11 casos de cisticercose intracraniana operados por se comportarem como processos tumorais. Eram 7 do sexo feminino e 4 do sexo masculino. A idade variava de 4 a 65 anos e o tempo de doença de 3 dias a 6 anos. Nove pacientes foram internados com cefaléia, vômitos e perturbações visuais sugestivas de hipertensão intracraniana. Uma paciente foi internada com diagnóstico de meningite linfomonocitária e o outro com crise convulsiva focal seguida de hemiparesia. Cinco pacientes apresentavam sinais focais e em 6 havia edema de papila. Crises convulsivas ocorreram em 45,5% dos casos. A radiografia simples de crânio não revelou calcificações em nenhum dos casos mas havia sinais de hipertensão intracraniana crônica em três pacientes. O eletrencefalograma acusou sofrimento cerebral em 8 pacientes. O líquido cefalorraquiano mostrou hipercitose discreta em 4 casos, hiperproteinorraquia em outros 4 pacientes e reação para cisticercose positiva em dois pacientes. A angiografia cerebral foi o exame que localizou a lesão expansiva sendo 4 na região temporal, três frontais, dois parietais, um no terceiro ventrículo e outro no quarto ventrículo. A intervenção cirúrgica permitiu a retirada de vesículas volumosas na intimidade do parênquima cerebral em 6 casos. Havia em torno destas vesiculas uma reação glial expessa. Em outro caso a vesícula era pequena mas aderente a parede do trígono ventricular provocando dilatação do polo temporal. Em dois casos formam retiradas vesículas únicas intraventriculares sendo uma no terceiro outra no quarto ventrículo. Nas duas

    There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 2012. Twenty articles were identified, in that, 12 literature reviews, 4 descriptive and exploratory studies, 2 expert opinions, one prospective cohort study and one was an experience report. The vesical intra-abdominal pressure measurement was considered gold standard. There are variations in the technique however, but some common points were identified: complete supine position, in absence of abdominal contracture, in the end of expiration and expressed in mmHg. Most research results indicate keeping the transducer zeroed at the level of the mid-axillary line at the iliac crest level, and instill 25mL of sterile saline. Strong evidence must be developed. RESUMO Em pacientes críticos com quadros abdominais agudos a esclarecer é crescente a solicitação da aferição da pressão intra-abdominal. Sintetizar resultados de pesquisas sobre a mensuração da pressão intra-abdominal pela via vesical e analisar o nível de evidência foram os objetivos desta revisão integrativa da literatura, realizada nas bases LILACS, MEDLINE e PubMed, no período de 2005 a julho de 2012. Identificaram-se 20 artigos, sendo 12 revisões de literatura, 4 estudos exploratório-descritivos, 2 opiniões de especialistas, 1 estudo de coorte prospectivo e 1 relato de experiência.

    AIM: To study the morphologic and cellular immunologic changes after homologous transplantation of the abdominal aorta in rats after programmed cryopreservation (-196°C).METHODS: Abdominal aorta was harvested from anesthetized Spraque Dawley (SD) rats for cryopreservation (group B) or immediate implantation (group A). The survival rates and apoptotic rates of aortic endothelial cells (ECs)were examined. The patency rates, histology and cellular immunologic changes of the abdominal aorta were examined on days 1, 3, 7, 14, 30, 60 after transplantation respectively.RESULTS: The survival rate of ECs after programmed cryopreservation was 90.1±1.79%, about 3.4% lower than that of uncryopreservation (93.5±1.96%). The apoptotic rates of ECs was increased after cryopreservation (7.15%vs 4.86%, P<0.05). The patency rate of group B was significantly higher than that of group A (91.6±12.9% vs 62.5±26.2%, P<0.01). CD4/CD8 ratio, TCR αβ and CD11b/CD18 ratio of group B were significantly lower than those of group A (P<0.05). Revivification of the cryopreserved abdominal aorta showed normal adventitia and intact smooth muscle cells.CONCLUSION: Cryopreservation can reduce homologous abdominal aortic antigenecity. Even if without administration of immunosuppressive agents, it is still feasible to implement homologous artery grafting in rats.

    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.

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

    Full Text Available 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.

    Management of chronic abdominal pain can be challenging. Sometimes patients fail to get adequate response from multiple medications and nerve blocks. We present a patient case report of chronic abdominal pain with a history of multiple surgeries managed successfully by neuromodulation of the transverse abdominis plane (TAP). The TAP block is a procedure in which local anesthetic is injected into the abdominal fascial plane that carries sensory nerves to the abdominal wall in order to block pain sensation. It has been shown to reduce postoperative pain and analgesic dependence after abdominal and gynecological surgeries. A 60-year-old woman presented to us for chronic abdominal pain for which medications provided little relief. She had an extensive history of abdominal surgeries and was also treated for lower back pain with surgery and less invasive procedures in the past. Under our care, she underwent 2 TAP blocks with almost complete resolution of her abdominal pain. Her pain, however, came back within a few of weeks of the procedures. Since our patient found pain relief from the TAP blocks, we proceeded with neurostimulation of the TAP for long-term pain relief. We placed a dorsal column stimulator 16 contact lead for lower back and leg pain and 8 contact leads placed in the TAP under ultrasound guidance. She has had multiple follow-ups since her TAP lead placement procedure with continued and near complete resolution of her abdominal pain. The TAP lead stimulation was helping her abdominal pain and the dorsal column lead stimulation was helping her back and leg pain.

    Full Text Available Background. Desmoids are benign tumors, with local invasive features and no metastatic potential, which have rarely been described to be pregnancy associated. Case. We described the rapid growth of an anterior abdominal wall mass in a 40-year-old pregnant woman. Due to its close proximity to the enlarged uterus, it was misdiagnosed to be a uterine leiomyoma by ultrasound examination. Final tissue diagnosis and radical resection were done at the time of abdominal delivery. Conclusion. Due to the diagnostic limitations of imaging techniques, desmoids should always be considered when the following manifestations are observed in combination: progressive growth of a solitary abdominal wall mass during pregnancy and well-delineated smooth tumor margins demonstrated by imaging techniques. This case emphasizes the importance of entertaining uncommon medical conditions in the differential diagnosis of seemingly common clinical manifestations.

    This study was designed to evaluate the effects of four specific sit-up exercises on muscular activity of the rectus abdominis. Pairs of surface electrodes were placed unilaterally on four quadrants of the rectus abdominis, delimited by tendinous inscriptions, in four male subjects. Electromyographic (EMG) recordings were taken while the subjects performed four different abdominal exercises. Each abdominal exercise was hypothesized to have a specific effect on one of the four quadrants of the rectus abdominis. The four exercises analyzed were: 1) long lying crunch, 2) bent knee crunch, 3) leg raise, and 4) vertical leg crunch. Analysis of the standardized EMG recordings demonstrated no significant differences in the mean muscle activity between the four different quadrants, in the mean muscle activity between the four different exercises, and in interactions between the exercises and the quadrants of the rectus abdominis. We conclude that none of the four abdominal exercises studied are specific for strengthening individual muscle quadrants of the rectus abdominis.

    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.)

    Full Text Available Abdominal wall endometrioma is a condition rarely seen by surgeons. It represents a diagnostic challenge due to its similarity with other tumors. This entity occurs in fertile women and often appears two to five years after gynecological and obstetric surgical procedures. It must be considered when dealing with a cyclically painful nodule located in a laparotomy scar. The diagnosis is established by histological examination; most imaging tests determine the characteristics of the lesion, concomitant lesions and the intra-abdominal origin or location in the abdominal wall. The cases of two patients treated at the General Surgery Department of the María Eugenia González Comprehensive Diagnostic Center in the Capital District, Venezuela, are presented. Wide excision of the tissue and histological examination were performed, confirming the diagnosis. The postoperative course was uneventful. This case is presented given the rarity of this condition.

    Background The effect of decompressive laparotomy on outcomes in patients with abdominal compartment syndrome has been poorly investigated. The aim of this prospective cohort study was to describe the effect of decompressive laparotomy for abdominal compartment syndrome on organ function and outcomes. Methods This was a prospective cohort study in adult patients who underwent decompressive laparotomy for abdominal compartment syndrome. The primary endpoints were 28‐day and 1‐year all‐cause mortality. Changes in intra‐abdominal pressure (IAP) and organ function, and laparotomy‐related morbidity were secondary endpoints. Results Thirty‐three patients were included in the study (20 men). Twenty‐seven patients were surgical admissions treated for abdominal conditions. The median (i.q.r.) Acute Physiology And Chronic Health Evaluation (APACHE) II score was 26 (20–32). Median IAP was 23 (21–27) mmHg before decompressive laparotomy, decreasing to 12 (9–15), 13 (8–17), 12 (9–15) and 12 (9–14) mmHg after 2, 6, 24 and 72 h. Decompressive laparotomy significantly improved oxygenation and urinary output. Survivors showed improvement in organ function scores, but non‐survivors did not. Fourteen complications related to the procedure developed in eight of the 33 patients. The abdomen could be closed primarily in 18 patients. The overall 28‐day mortality rate was 36 per cent (12 of 33), which increased to 55 per cent (18 patients) at 1 year. Non‐survivors were no different from survivors, except that they tended to be older and on mechanical ventilation. Conclusion Decompressive laparotomy reduced IAP and had an immediate effect on organ function. It should be considered in patients with abdominal compartment syndrome. PMID:26891380

    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.

    Full Text Available Introduction: Superficial abdominal reflex (SAR is an important part of the neurologic assessment. It is normally present and may be present or absent in various physiological as well as pathological conditions. The presence of an abdominal incision creates a dilemma in the mind of the clinician for it affecting this reflex. As there is no literature on this, we decided to study the effect of abdominal incisions on SAR. Materials and Methods: It was a prospective, observational study. We evaluated the patients requiring transverse subcostal incision (range 3–12 cm both preoperatively and postoperatively, for their abdominal reflexes. Patients with preoperative normal and symmetrical abdominal reflexes were included in the study. Postoperatively, we compared the change of SAR with the preoperative status and analyzed the data. Results: A total of 94 patients underwent surgeries, out of which 54 patients came under inclusion criteria, comprising 36 males and 18 females. Subcostal transverse abdominal incisions were made for surgeries including both gastrointestinal and ventriculoperitoneal shunts. SAR was found unaffected by the incisions in all patients. Conclusions: Although the study was small, subcostal transverse abdominal incisions were not found to affect SAR.

    La endocrinología, como rama moderna de la ciencia, nació prácticamente en el siglo xx. No olvidemos que fueron Sterling y Bayliss en 1905 los que acuñaron el término “hormona” (del griego “homeos”, yo excito … para referirse a un mensajero químico, que procedente de la mucosa intestinal, viajaba a través de la corriente sanguínea para estimular la producción de jugo pancreático, y lo denominaron “secretina”.

    Es cierto que en 1849 Berthold había realizado un pionero pero opaco experimento, pues incluso él mismo le restó importancia, en el que se demostró que al castrar y trasplantar los testículos de gallos a la cavidad abdominal no se producían los síntomas deficitarios que se ven en el capón; habla él de la influencia de su secreción sobre la sangre y a través de esta sobre el organismo en general.

    Tampoco olvidemos que Claude Bernard, de quien se dijo que “no era un fisiólogo, sino la fisiología misma”, hablaba unos años más tarde del “medio interno” al considerar la glucosa – un combustible metabólico y no una hormona -, la “secreción interna” del hígado; pero él fue más allá y habló de la homeostasis o equilibrio de ese medio interno hormonal.

    Aunque poco después en Londres Addison describió la enfermedad que lleva su nombre y la relacionó con la suprarrenales, una de las tantas glándulas en que famosos anatomistas en buen número habían fracasado en demostrarles un conducto excretor, no fué sino hasta 1899, cuando la endocrinología tomó cuerpo, pues Carlos Eduardo Brown-Sequard, discípulo de Bernard y a la sazón Presidente de la Sociedad de Biología de París, dio a conocer los resultados de su sensacional aunque falaz experimento en donde su esposa y él se habían “rejuvenecido” al usar inyecciones de jugo testicular canino; el gran despliegue publicitario despertó mucho interés en este campo.

    Full Text Available Objetivo: determinar o papel da histerossonografia na avaliação das anormalidades da cavidade uterina, em pacientes com sangramento uterino anormal, selecionadas previamente pela ultra-sonografia transvaginal. Métodos: foram selecionadas 48 pacientes na menacme e pós-menopausa, portadoras de sangramento uterino anormal e anormalidades da cavidade uterina, diagnosticadas inicialmente pela ultra-sonografia transvaginal. Todas as pacientes se submeteram à histerossonografia e, posteriormente, aos métodos "padrão ouro", a histeroscopia e/ou histerectomia. As histerossonografias foram avaliadas por dois diferentes médicos e os diagnósticos confrontados. Resultados: a histerossonografia mostrou ter alta sensibilidade e especificidade no diagnóstico das patologias benignas da cavidade uterina. Na presença de pólipo a sensibilidade e a especificidade do método foram, respectivamente, de 100 e 97%, seguido do mioma submucoso cuja sensibilidade e especificidade foram, respectivamente, de 83 e 100%. Já na hiperplasia endometrial e no endométrio normal a sensibilidade e especificidade foram de 100%. Diagnosticamos 33 casos de pólipos, 13 casos de miomas submucosos, quatro casos de hiperplasia endometrial e três casos normais na análise dos métodos "padrão ouro". Houve alta correlação entre os diagnósticos dados pelos dois examinadores. Conclusões: a histerossonografia mostrou ser um exame reprodutível, com alta sensibilidade e especificidade no diagnóstico das patologias benignas da cavidade uterina em pacientes com sangramento uterino anormal.Purpose: to determine the role of sonohysterography in the evaluation of abnormalities in the uterine cavity in patients presenting abnormal uterine bleeding, who had previously been selected by transvaginal ultrasonography.

    2008-10-01

    Full Text Available A deficiência transversal da maxila é uma anomalia dentofacial relacionada à diminuição do diâmetro do arco maxilar. Este tipo de deformidade está muitas vezes associado a deficiência respiratória nasal, sendo um importante fator etiopatogênico. O tratamento desta atresia pode ser realizado através da Expansão Rápida da Maxila ou Expansão Rápida da Maxila Cirurgicamente Assistida, ficando na dependência da idade do paciente. Ambos os procedimentos levarão a mudanças na estrutura craniofacial, especialmente na cavidade nasal. OBJETIVO: Através da descrição de trabalhos levantados na literatura, procurou-se relatar a relação existente entre a expansão maxilar, cavidade nasal e resistência aérea nasal. MÉTODO: Foi realizada uma tradicional revisão assistemática da literatura, utilizando trabalhos do tipo experimentais, incluindo os que utilizaram Expansão Rápida da Maxila e Expansão Rápida da Maxila Cirurgicamente Assistida, e excluindo os que utilizaram Expansão Maxilar por Osteotomia Segmentada para o tratamento da atresia maxilar. RESULTADO: Tanto a Expansão Rápida da Maxila quanto a Expansão Rápida da Maxila Cirurgicamente Assistida levam a mudanças dentofaciais, especialmente sobre a cavidade nasal, causando um aumento da largura nasal, o que pode levar à diminuição da Resistência Aérea Nasal. CONCLUSÃO: Através dos estudos cefalométricos ântero-posteriores, fica evidente o aumento da largura da cavidade nasal após expansão maxilar.Mandibular cross-sectional deficiency is a dentofacial defect in connection with the narrowing of the mandibular arch width. This abnormality is a significant etiopathogenic factor and it is often associated with nasal breathing difficulties. This atresia may be treated through Rapid Maxillary Expansion or Surgically Assisted Rapid Maxillary Expansion, depending on the patient's age. Both procedures will change the craniofacial structure, especially the nasal cavity

    Full Text Available A matriz extracelular no carcinoma epidermóide da cavidade oral sofre modificações qualitativas e quantitativas durante a sua progressão. Estas alterações parecem possibilitar os processos de invasão e metástase que caracterizam as neoplasias malignas e são mais evidentes na interface tumor-hospedeiro. No nosso estudo, 23 biópsias incisionais de carcinomas epidermóides de diversas localizações da cavidade oral foram classificadas segundo o sistema de graduação histológica preconizado por Anneroth et al.¹ (1987. Foram utilizadas as colorações pela H. E. e a do tipo picrosirius, específica para colágeno. A expressão imuno-histoquímica do colágeno tipo I foi analisada em lesões com diferentes escores histológicos de malignidade. Pôde-se concluir que o colágeno apresenta diferentes padrões morfológicos, histoquímicos e imuno-histoquímicos em lesões com altos e baixos escores de malignidade.An analysis of the extracellular matrix at the invasive front of squamous cell carcinoma of the oral cavity may improve the understanding of tumour cell matrix interactions during malignancy growth. Alterations in collagen I expression may influence cellular invasion and metastasis. In this work, 23 cases of squamous cell carcinoma were submitted to the Anneroth's malignancy grading system¹. H. E. and sirius red staining were used. Immunohistochemical expression of collagen type I protein was observed in different malignancy scores.

This technical-economic study was divided into three parts: — Dividing walls (environmental noises — Floors (impact noises — Special Solutions (double walls, floating floors, etcetera The results show that in developing countries the most costly solutions are not always the best for housing, as far as soundproofing is concerned. A good knowledge of the economic aspects related to this matter allows obtaining a good quality at a moderate cost, which is a priority in this type of country.

    El objetivo general de este trabajo fue el de analizar el comportamiento de la relación costo-aislamiento acústico en soluciones constructivas alternativas para muros interiores y entrepisos. Este estudio técnico-económico comprende tres partes: * Muros divisorios (ruidos aéreos. * Entrepisos (ruidos de impacto. * Soluciones especiales (muros de doble hoja, pisos flotantes, etc. Se llega a la conclusión que, en los países en desarrollo, no siempre las mejores soluciones para la vivienda, desde el punto de vista acústico, son las de mayor costo. Conocer en profundidad los aspectos económicos de esta cuestión significa poder lograr una buena calidad con costos moderados, lo cual constituye una prioridad en este tipo de países.

    Full Text Available Resumo Bacteriocinas são peptídeos antimicrobianos sintetizados nos ribossomos, tendo sido descrita uma grande diversidade de bacteriocinas, as quais diferem entre si quanto a composição de aminoácidos, biossíntese, transporte e modo de ação. Nos alimentos, as bacteriocinas podem ser encontradas naturalmente como produtos da microbiota normal ou introduzida (cultura starter ou probióticos. Devido às suas aplicabilidades frente a organismos patogênicos contaminantes em alimentos, vários estudos têm sido publicados, tornando o uso destes peptídeos uma alternativa aos conservantes químicos tradicionais. Considerando-se as propriedades das bacteriocinas e sua potencial aplicação como bioconservadores de alimentos e alternativa aos antibióticos, o presente estudo busca acercar-se de uma visão geral das bacteriocinas quanto aos aspectos históricos, sistemas de classificação, biossíntese e transporte, modo de ação, abordando também algumas de suas aplicações na indústria de alimentos.

    Objective: A retrospective study to determine the success and complications of abdominal sacral colpopexy in correcting massive genital prolapse over an 8-year period between September 1989 and January 1997.Methods: The charts were reviewed for 3 patients with massive procidentia and 15 patients with symptomatic posthysterectomy vaginal vault prolapse, who desired preservation of sexual function and underwent abdominal sacral colpopexy with Marlex mesh at two community teaching hospitals.Results: In 16 of the 18 patients, one or more concurrent procedures were performed at the same time, including three Burch colpocystourethropexies and one Raz bladder neck suspension, which successfully controlled urinary stress incontinence. In three cases, staging procedures were done for ovarian neoplasia. There were no intraoperative complications. One patient developed a superficial abdominal wound infection, one patient had a deep venous thrombosis in her left leg 7 days postoperatively, and one patient experienced a 1 cm area of graft erosion 10 months postoperative requiring partial resection. Duration of follow-up has varied from 8 months to 5 years. One patient died 43 months after surgery of unrelated causes. No patients developed recurrent prolapse.Conclusions: Abdominal sacral colpopexy is a successful operation for the correction of prolapse. Serious complications are infrequent. Photographs of the technique and a review of the literature are presented.

    In an effort to develop referral criteria for the ordering of abdominal radiographs for patients presenting with abdominal symptoms, we prospectively studied the relation between clinical data and radiographic abnormalities. Of 1780 examinations, 179 (10.0%) showed some radiographic abnormality. If abdominal radiographs would have been limited to those patients who had moderate or severe abdominal tenderness, or to patients with a high clinical suspicion of bowel obstruction, renal or ureteral calculi, trauma, ischemia, or gallbladder disease, regardless of the degree of tenderness, 956 (53.7%) examinations would not have been done. All radiographic abnormalities reflecting a serious pathologic process would have been identified. Only 33 (3.5%) abnormalities of limited significance, almost all localized or generalized ileus, would have been undetected. The adoption of these referral criteria would result in minimal loss of clinically useful information, large financial savings, and a reduction in radiation exposure.

    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

Background: Patients with previous multiple abdominal surgeries are often denied abdominal free flap breast reconstruction because of concerns about flap viability and abdominal wall integrity. We therefore studied their flap and donor site outcomes and compared them to patients with no previous abdominal surgery to find out whether this is a valid contraindication to the use of abdominal tissue. Patients and Methods: Twenty patients with multiple previous abdominal operations who underwent abdominal free flap breast reconstruction by a single surgeon (C.M.M., 2000-2009) were identified and retrospectively compared with a cohort of similar patients without previous abdominal surgery (sequential allocation control group, n = 20). Results: The index and control groups were comparable in age, body mass index, comorbidities, previous chemotherapy, and RT exposure. The index patients had a mean age of 54 years (r, 42-63) and an average body mass index of 27.5 kg/m2 (r, 22-38). The main previous surgeries were Caesarean sections (19), hysterectomies (8), and cholecystectomies (6). They underwent immediate (n = 9) or delayed (n = 11) reconstructions either unilaterally (n = 18) or bilaterally (n = 2) and comprising 9 muscle-sparing free transverse rectus abdominis muscle and 13 deep inferior epigastric perforator flaps. All flaps were successful, and there were no significant differences in flap and donor site outcomes between the 2 groups after an average follow up of 26 months (r, 10-36). Conclusion: Multiple previous abdominal

    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 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.

    Full Text Available São estudados os mecanismos psíquicos que se desenvolvem em agrupamentos humanos e a sua utilização para fins terapêuticos, sendo focalizado o fenômeno da interação como o dinamismo básico dessas reações. O autor compara a forma pela qual encara o grupo com as idéias de Bion, Moreno e Sullivan, encarando a hipótese de que os sentimentos de amor e hostilidade se manifestem em função do bom ou do mau funcionamento dos contactos primários que caracterizam a dependência. O autor comenta resultados que obteve usando o psicodrama, mediante o qual estudou reações emocionais de inveja, ódio, agressividade e amor. O autor analisa as técnicas de Slavson e Pratt baseando-se nos dinamismos inerentes ao grupo e refere os estudos de Beukemkamp para a compreensão do fenômeno transferenciai que, no grupo, tem características próprias. As diferenças entre a terapia de grupo e a individual são apontadas, sendo a contra-transferência considerada como elemento construtivo. Pensa o autor que o aspecto dramático vivenciado pelo grupo ou por um dos seus componentes tem alto valor, pois engloba a verbalização, os componentes emocionais e os componentes posturais. O tono emocional vivenciado pelo grupo é mais intenso e opressivo que o que é despertado na terapêutica individual, o que é explicável pela somação de efeitos provocada pela reação circular. Segundo o autor, a Psicoterapia de Grupo e a Psicoterapia Individual não se opõem, mas se completam.

    Chronic abdominal pain is a common clinical problem in primary care, and is usually referred to gastroenterologists or general surgeons. Although up to 20% of cases of idiopathic abdominal pain arise in structures of the abdominal wall, this is frequently overlooked as a possible cause. It includes pain arising from structures of the abdominal wall including skin, parietal peritoneum, cellular subcutaneous tissue, aponeuroses, abdominal muscles and somatosensorial innervation from lower dorsal roots. The diagnosis is based on anamnesis and physical examination. Carnett's sign is a simple maneuver that discriminates between parietal and visceral pain. Management with topical anesthesia is effective in a majority of patients and can help to confirm the diagnosis.

    Gravity of abdominal vessels traumatisms is secondary to multiple factors. It depends on the type of injured vessels, aetiology and associated lesions. Between September 1984 and March 1995, 22 abdominal vessel traumatisms in 16 patients (mean age: 39 years) were treated. At surgical exploration, 4 aortic and 2 renal vein lesions, 7 iliac artery and 3 renal artery contusions, 2 superior mesenteric artery dissections; 3 infra-renal vena cava ruptures and 1 superior mesenteric vein dilaceration were found. All lesions were caused by penetrant wounds secondary to firearm or blade injury or secondary to injuries due to ski or traffic accidents. In 5 cases, lesions were iatrogenic. There was no mortality in the post-operative period, 14 patients out of the 16 patients operated on have been followed during a period from 1 to 120 months.

    Abdominal cocoon,the idiopathic form of sclerosing encapsulating peritonitis,is a rare condition of unknown etiology that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a fibrocollagenous membrane.Preoperative diagnosis re quires a high index of clinical suspicion.The early clinical features are nonspecific,are often not recognized and it is difficult to make a definite pre-operative diagnosis.Clinical suspicion may be generated by the recurrent episodes of small intestinal obstruction combined with relevant imaging findings and lack of other plausible etiologies.The radiological diagnosis of abdominal cocoon may now be confidently made on computed tomography scan.Surgery is important in the management of this disease.Careful dissection and excision of the thick sac with the release of the small intestine leads to complete recovery in the vast majority of cases.

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

    10 patients with adrenal damage were observed during 2.5 years. It amounted 0.93% of all patients with closed abdominal injuries. The right adrenal gland was traumatized in all cases evidently due to it's compression between right lobe of liver and vertebral column. Adrenal damage is observed quite often in combination with injuries of right liver lobe, right kidney and retroperitoneal hematoma formation. 5 patients underwent laparotomy on account of intra-abdominal bleeding, but adrenal damage was never revealed. Ultrasound and tomographic semiotics of adrenal damage was worked out, which allowed ascertaining diagnosis in 80% on application of ultrasound study and in 100% at computer tomography. Injury of one adrenal gland was not accompanied by adrenal failure and did not require hormonal replacement therapy.

    Leiomyosarcomas are soft tissue tumors that account for approximately 15% of all soft tissue sarcomas. Leiomyosarcomas may be located at almost any part of the abdomen but especially are more common in the retroperitoneum, followed by gastrointestinal tract and genital system. They develop mainly in adult life and are very rare in children. In this article, imaging findings of leiomyosarcomas in various abdominal locations are presented. Radiologic studies are capable of providing useful information on the localization, size, changes in the internal structure of the tumor, its extension and invasion. Leiomyosarcoma should be considered in the differential diagnosis in case of detection of a large, circumscribed, and heterogenous abdominal mass. Histopathologically, diagnosis of malignancy depends particularly on mitotic counts, size, rate of necrosis, and infiltrating margins. (orig.)

    Two cases illustrate the clinical manifestations and angiographic findings associated with segmental stenosis of the abdominal aorta. Such lesions represent the chronic occlusive stage of Takayasu's disease, a nonspecific inflammatory arteritis of uncertain etiology. While the disease is considered autoimmune, an infectious process may be involved. Complications typically associated with stenotic lesions of the abdominal aorta are secondary renal hypertension and ischemic symptoms secondary to vascular insufficiency. Surgical correction, the treatment of choice, has achieved excellent results for these well-localized lesions. Secondary renal hypertension was relieved by a spenorenal shunt and the disease has since been controlled with conservative management in the first patient. An aortofemoral bypass graft successfully alleviated the vascular insufficiency in the second patient, although the patient unfortunately expired from a refractory postoperative cardiac complication.

    Mast cells (MCs) are proinflammatory cells that play important roles in allergic responses, tumor growth, obesity, diabetes, atherosclerosis, and abdominal aortic aneurysm (AAA). Although the presence and function of MCs in atherosclerotic lesions have been thoroughly studied in human specimens...... neighboring cells, degrade extracellular matrix proteins, process latent bioactive molecules, promote angiogenesis, recruit additional inflammatory cells, and stimulate vascular cell apoptosis. These activities associate closely with medial elastica breakdown, medial smooth-muscle cell loss and thinning...

    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.

    Full Text Available Duodenal diverticuli are acquired false diverticuli of unknown etiology. Although mostly asymptomatic, they can occasionally cause upper gastrointestinal hemorrhage, rarely with massive bleeding. In this report, we present (to the best of our knowledge the first reported case of duodenal diverticular bleeding, causing abdominal compartment syndrome. Albeit a rare event, duodenal diverticular bleeding should be included in the differential diagnosis of upper gastrointestinal bleeding. As with our case, a multidisciplinary approach to managing such patients is crucial.

    Focal epilepsy with ictal abdominal pain is an unusual partial epilepsy characterized by paroxysmal episodes of abdominal or visceral pain, disturbance of awareness and electroencephalographic abnormalities. We describe a new case of ictal abdominal pain in which gastrointestinal complaints were the only manifestation of seizures and review the previously described pediatric patients. In our patient clinical findings, ictal EEG abnormalities, and a good response to antiepileptic drugs allowed us to make a diagnosis of focal epilepsy with ictal abdominal pain. This is a rare epileptic phenomenon that should be suspected in patients with unexplained paroxysmal abdominal pain and migraine-like symptoms. We suggest that, after the exclusion of more common etiologies, focal epilepsy with ictal abdominal pain should be considered in patients with paroxysmal abdominal pain and ictal EEG abnormalities.
