    Full Text Available Resumo Objetivou-se analisar os fatores associados ao índice de adiposidade corporal. Um estudo transversal de base populacional foi conduzido com 964 adultos, de 20 e 59 anos, em Viçosa, MG, Brasil. Aplicou-se questionários domiciliares e medidas antropométricas para se obter os dados. A análise múltipla foi realizada por meio de regressão linear, ajustada pelo efeito do desenho amostral. A prevalência de excesso de adiposidade corporal foi 36,89 (IC 30,81–43,43, sendo mais elevada nos homens (48,18% - IC 39,09–57,34. Associou-se positivamente com o índice de adiposidade corporal o sexo feminino (p = 0,002, idade em anos (p < 0,001, aqueles que viveram com companheiro (p = 0,022 e com insatisfação com a imagem corporal (p < 0,001. A autoavaliação da saúde positiva (p = 0,048 esteve associada negativamente com o índice de adiposidade corporal. A prevalência de excesso de adiposidade corporal foi elevada, sendo o sexo, a faixa etária, o estado civil, a autoavaliação da saúde e a insatisfação com a imagem corporal fatores determinantes para o aumento da adiposidade corporal, nesta população, indicando um forte risco para doenças crônicas não transmissíveis decorrentes do excesso de adiposidade.

    Full Text Available O objetivo deste estudo foi analisar os níveis de adiposidade corporal em crianças de baixa renda de 5 a 10 anos de idade, residentes na região de abrangência de Secretaria de Desenvolvimento Regional de São Miguel do Oeste/SC. Para tanto, 1089 crianças foram avaliadas. Realizou-se a avaliação do percentual de gordura (%G através da classificação proposta por Lohman. Os resultados apontam uma maior prevalência de meninas com nível de gordura “baixo” em comparação aos meninos (29,1% e 8,9%, respectivamente. Por outro lado, houve um maior percentual de meninos com adiposidade “alta” em relação às meninas (17,6% e 13,7%, respectivamente. No entanto, a maior parte dos meninos e meninas avaliados (73,5% e 57,1 %, respectivamente apresentaram porcentagem de gordura “adequada” para a idade. Conclui-se que há a necessidade de implantação de programas de prevenção e intervenção na região, pois altas prevalências de desnutrição e obesidade foram observadas.

    Full Text Available OBJETIVO: Associar o tempo de amamentação exclusiva da criança à adiposidade central e periférica, por meio do índice de massa corporal, dos perímetros da cintura e do braço, e das dobras cutâneas triciptal, subescapular e a somatória destas em pré-escolares. MÉTODOS: Pesquisa de delineamento transversal, em que 134 pré-escolares entre três e cinco anos de idade de uma escola par-ticular de Brasília, DF, foram avaliados quanto a: massa corporal, estatura, perímetros do braço e da cintura, dobras cutâneas triciptal e subescapular. Os pais das crianças responderam a um questionário sobre tempo de amamentação. O diagnóstico de sobrepeso e obe-sidade foi realizado de acordo com a classificação da Organização Mundial da Saúde para o índice de massa corporal por idade. RESULTADOS: As meninas tiveram maior concentração adiposa na dobra cutânea triciptal (p=0,001, subescapular (p=0,044 e na somatória destas (p=0,003 em relação aos meninos. A prevalência de sobrepeso e obesidade foi similar nos dois sexos (25,4% nos meninos e 22,6% nas meninas, assim como o tempo médio de amamentação exclusiva (4,3 meses para meninos e 4,6 meses para meninas. Notou-se correlação inversa significativa entre tempo de amamentação exclusiva e perímetro da cintura (r=-0,166; p=0,05. As demais variáveis também mostraram tendência de correlação inversa com o tempo de aleitamento materno exclusivo, porém sem valores significativos. CONCLUSÕES: A associação inversa entre o tempo de ama-mentação e o perímetro da cintura mostra um possível efeito do aleitamento materno sobre a distribuição de gordura corporal no pré-escolar.OBJETIVO: Asociar el tiempo de amamantamiento exclusivo del niño con la adiposidad central y periférica mediante el índice de masa corporal, perímetros de la cintura y del brazo, y pliegues cutáneos ticipital, subescapular y la suma de estos en pre-escolares.

    Full Text Available Objetivo: analisar isoladamente o componente adiposo subcutâneo durante o ciclo menstrual. Método: a amostra foi composta por 30 mulheres saudáveis com idade entre 18 e 25 anos, com ciclo menstrual regular e que não utilizavam anticoncepcional oral ou injetável no período do estudo, na cidade de Fortaleza-CE, Brasil. A adiposidade corporal foi predita a partir da quantificação do somatório de seis dobras cutâneas (S ADIP. Essa variável foi utilizada no cálculo do escore de proporcionalidade (Z ADIP, subsidiando a realização do cálculo da massa adiposa absoluta (M ADIP. Resultados: a média de idade foi de 21,8 anos e de estatura 162,2 cm. Considerando a disposição de adiposidade por dobra cutânea, durante as três fases do ciclo menstrual, as dobras tricipital, subescapular, abdominal e espinal apresentaram maior média na fase lútea (14,8; 11,9; 19,5; 10,6 respectivamente; a dobra coxa apresentou valores de médias estatisticamente semelhantes nas fases folicular e ovulatória (20,1 e a dobra perna apresentou maior média na fase folicular (13,4. Analisando a prevalência do maior somatório de dobras cutâneas e a relação com a maior quantificação de massa adiposa absoluta, constatou-se que a fase folicular apresentou a maior média de somatório de dobras (89,6 e de massa adiposa (19,3. Considerações finais: os dados encontrados revelam que, durante as fases do ciclo menstrual, não há diferença significativa no somatório das dobras cutâneas e de massa adiposa absoluta. Este fato sugere que as alterações hormonais ocorridas durante o ciclo não estão diretamente associadas com o fator de variabilidade da adiposidade corporal.

    1995-01-01

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

    Full Text Available Objetivo: Identificar fatores sociodemográficos e comportamentais associados à obesidade abdominal (OA e ao percentual de gordura corporal elevado (%GC elevado em adolescentes de Curitiba-PR. Métodos: A amostra probabilística foi composta por 1.732 adolescentes, de 11 a 19 anos, de ambos os sexos, da rede pública de ensino. Foram coletadas as medidas de dobras cutâneas tricipital e panturrilha para o cálculo do %GC, além da medida da circunferência da cintura. Um questionário foi preenchido pelos adolescentes para avaliação das seguintes variáveis: sexo, idade, tipo de residência, nível socioeconômico, tempo gasto assistindo à TV durante a semana e o fim de semana, além do gasto energético diário. A regressão logística foi utilizada como medida de associação dos fatores sociodemográficos e comportamentais com a obesidade abdominal e o percentual de gordura corporal elevado. Resultados: As meninas apresentaram maior chance de ter o %GC elevado (OR: 2,73; IC95%: 2,32-3,33. Em contrapartida, têm menor chance de ter obesidade abdominal (OR: 0,58; IC95%: 0,44-0,78. Indivíduos mais velhos (16-19 anos apresentaram maior chance de ter o %GC elevado (OR: 1,36; IC95%: 1,02-1,83. Em contrapartida, as faixas etárias mais elevadas (13-15 anos e 16-19 anos tiveram uma associação inversa com a obesidade abdominal. Em relação ao gasto energético diário, os indivíduos menos ativos apresentaram maior chance de ter %GC elevado (OR: 1,36; IC95%: 1,07-1,71 e obesidade abdominal (OR: 1,40; IC95%: 1,09-1,80. Conclusões: Intervenções relacionadas ao aumento nos níveis de atividade física na população jovem devem ser elaboradas para o combate do excesso de adiposidade corporal.

    Full Text Available FUNDAMENTO: Adolescentes com excesso de adiposidade e eutróficas apresentam as mesmas alterações metabólicas esperadas em indivíduos obesos. OBJETIVO: Avaliar a composição corpórea, alterações antropométricas, bioquímicas e clínicas de adolescentes do sexo feminino. MÉTODOS: Foram avaliadas 113 adolescentes de escolas públicas de Viçosa, MG, divididas em três grupos: grupo 1 - constituído por adolescentes eutróficas com excesso de gordura corpórea; grupo 2 - eutróficas com gordura corpórea dentro dos limites de normalidade; e grupo 3 - com excesso de peso e de gordura corpórea. Peso, estatura, circunferência da cintura e quadril, pressão arterial foram aferidos. O índice de massa corporal (IMC e a relação cintura-quadril foram calculados. O porcentual de gordura corpórea foi obtido pela impedância bioelétrica horizontal, seguindo protocolo próprio para a referida avaliação. A avaliação do porcentual de gordura corpórea e bioquímica foi realizada após 12 horas de jejum, sendo analisados perfil lipídico, glicemia e insulina, homocisteína, leptina e Proteína C Reativa. A resistência à insulina foi calculada pelo índice HOMA. RESULTADOS: O grupo das adolescentes eutróficas, com elevada adiposidade, comportou-se, em relação à pressão arterial, fração HDL e glicemia, de modo semelhante às adolescentes com excesso de peso. Pode-se perceber que o índice HOMA, a insulina e a leptina aumentaram de acordo com o aumento da gordura corpórea. Mais da metade das adolescentes apresentava valores de colesterol total e PCR acima dos níveis recomendados. A alteração metabólica mais evidente relacionou-se ao perfil lipídico para os grupos estudados. CONCLUSÃO: O excesso de adiposidade em adolescentes eutróficas pode estar relacionado a alterações bioquímicas e clínicas semelhantes àquelas encontradas em adolescentes com excesso de peso.

Estudo epidemiológico transversal realizado em 1.531 escolares (6-17 anos da rede de ensino pública do município de Cascavel, PR, Brasil. A adiposidade corporal foi estimada pela técnica de dobras cutâneas. Foram coletadas informações referentes à idade, nível econômico e estágio maturacional, bem como ao desempenho nos testes de sentar e alcançar, abdominal em 1 minuto, impulsão horizontal e Shuttle run. As análises (teste t de student não pareado e regressão de Poisson foram realizadas por nível econômico alto e baixo (baixo+médio, com nível de significância de 5%. A prevalência de adiposidade corporal elevada foi de 30,4%, sendo maior (p<0,05 naqueles de nível econômico alto (33,3% vs 28,3%. Após ajuste para todas as variáveis, no nível econômico baixo, a adiposidade corporal elevada se associou a baixa resistência abdominal (RP=1,44; IC95%=1,05-1,99 e potência de membros inferiores (RP=2,09; IC95%=1,46-1,98. No nível econômico alto, o desfecho foi associado à baixa resistência abdominal (RP=1,72; IC95%=1,17-2,51 e, à média (RP=2,83; IC95%=1,76-4,55 e baixa (RP=3,90; IC95%=2,38-6,38 potência de membros inferiores. Em ambos os estratos sociais, o menor desempenho muscular (resistência abdominal e potência de membros inferiores conferiu maior probabilidade de ter adiposidade corporal elevada. Porém, a magnitude das valências musculares associadas à adiposidade corporal elevada parece diferir de acordo com o nível econômico.

    Full Text Available Introduction. Intraabdominal abscesses are in 98-99% cases the result of secondary and only in 1-2% of primary peritonitis. They are easy and successfully diagnosed. Abdominal abscesses of unknown cause are extremely rare. Case Outline. The authors present a 68-year-old man, without significant data in past history, who suddenly developed epigastric pain, nausea, vomiting and leukocytosis which was treated with antibiotics resulting in the alleviation of complaints and reduction of white blood cells count. After five days ultrasonography showed incapsulated collection of dense fluid in the epigastrium confirmed by CT scan two days later. Upper endoscopy excluded ulcer and/or perforation of the stomach and duodenum. Under local anesthesia, through the upper part of the left rectal muscle, puncture followed by incision was done, and about 50 ml of dense pus was removed. Finger exploration of the cavity showed no foreign body within the cavity. Using drainage, the recovery was quick and uneventful. By preoperative and postoperative abdominal investigations no cause of the abscess was found. Two and a half years after surgery the patient remained symptom-free with normal clinical, laboratory and ultrasonographic findings. Conclusion. The authors presented an intraabdominal abscess of unknown cause that was successfully treated with antibiotics, percutaneous puncture and drainage under local anaesthesia. In spite of all diagnostic methods the cause of the abscess could not be found. Thus, such a possibility, although being rare, should be taken into account.

    Pseudomycetomas are deep cutaneous to subcutaneous lesions caused by Microsporum canis mainly described in Persian cats, with few reports of intra-abdominal location. This report describes the clinical signs and lesions of intra-abdominal pseudomycetomas caused by M. canis in two Persian cats. Two Persian cats with a history of previous laparotomy (ovariohysterectomy and nephrostomy) and fecal impaction were examined. Cat #1 was euthanized and subjected to necropsy, histopathology and mycological evaluation. Cat #2 presented with chronic dermatophytosis, and an intra-abdominal mass, that was subjected to histopathology evaluation. Cat #1 presented at necropsy a white-grayish, firm mass (6cm×3.5cm×2.8cm) in the uterine cervix. Cat #2 presented a firm whitish mass (6.5cm×1.5cm×0.5cm) located close to the left kidney. Histologically, both masses contained multifocal granules with hyphae and spores surrounded by Splendore-Hoeppli reaction, with a pyogranulomatous inflammatory infiltrate and fibrous connective tissue proliferation in the periphery. Hyphae and spores exhibited marked Grocott and periodic acid-Schiff staining. M. canis was identified by fungal isolation in cat #1. Pseudomycetoma should be considered as a differential diagnosis in cats, especially in Persian cats presenting with an intra-abdominal mass. Entrance of the agent into the cavity can occur during laparotomy. Copyright © 2016 Asociación Española de Micología. Publicado por Elsevier España, S.L.U. All rights reserved.

    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.

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

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

    One hundred three patients underwent abdominoplasty combined with other intraabdominal procedures including 67 tubal ligations, 34 total abdominal hysterectomies and 2 cholecystectomies, from January 1983 to July 1991. The patients were divided into two groups, those undergoing the standard or total abdominoplasty and those undergoing limited abdominoplasty with or without liposuction in delimited areas. In this series of 103 patients, we found only two minor complications and only three patients were transfused with autologous units of blood. When performed by well-schooled surgical teams, abdominoplasty may be combined with intraabdominal procedures with gratifying results.

MÉTODOS: Foram avaliadas 113 adolescentes de escolas públicas de Viçosa, MG, divididas em três grupos: grupo 1 - constituído por adolescentes eutróficas com excesso de gordura corpórea; grupo 2 - eutróficas com gordura corpórea dentro dos limites de normalidade; e grupo 3 - com excesso de peso e de gordura corpórea. Peso, estatura, circunferência da cintura e quadril, pressão arterial foram aferidos. O índice de massa corporal (IMC e a relação cintura-quadril foram calculados. O porcentual de gordura corpórea foi obtido pela impedância bioelétrica horizontal, seguindo protocolo próprio para a referida avaliação. A avaliação do porcentual de gordura corpórea e bioquímica foi realizada após 12 horas de jejum, sendo analisados perfil lipídico, glicemia e insulina, homocisteína, leptina e Proteína C Reativa. A resistência à insulina foi calculada pelo índice HOMA. RESULTADOS: O grupo das adolescentes eutróficas, com elevada adiposidade, comportou-se, em relação à pressão arterial, fração HDL e glicemia, de modo semelhante às adolescentes com excesso de peso. Pode-se perceber que o índice HOMA, a insulina e a leptina aumentaram de acordo com o aumento da gordura corpórea. Mais da metade das adolescentes apresentava valores de colesterol total e PCR acima dos níveis recomendados. A alteração metabólica mais evidente relacionou-se ao perfil lipídico para os grupos estudados.

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

    Full Text Available Context Intra-abdominal sepsis has significant morbidity and mortality. In the developed world, there are many common causes originating from the lower gastrointestinal tract including diverticular disease, appendicitis, perforated cancers, and inflammatory bowel disease. It has a high cost and is associated with high levels of significant morbidity and mortality. Management options include radiologic drainage and surgical options include resection for more widespread sepsis. Laparoscopic surgery has increased and has been useful in elective setting. Its use in the emergency setting is less evaluated. Evidence Acquisition Evidence was acquired by searching online medical databases including Pubmed, Medline and Embase. Results Laparoscopic surgery has been shown to have a role in the acute setting. Studies show it has become the gold standard in the appendicitis. High quality Randomized controlled trials are in short supply but observational and cohort studies have shown equivalence and with increasing experience complication rates are reduced. Evidence is also increasing in the management of diverticular disease, crohn’s and ulcerative colitis as well as post-operative complication management and acute presentations of colorectal cancer. Conclusions Laparoscopic surgery is feasible in the management of intra-abdominal sepsis. It has become the new accepted standard in the management of appendicitis, and is safe, feasible and increasing in the management of complex diverticular disease, acute IBD and colorectal cancer in the emergency and post-operative setting.

    In a 3-year period, 21 intraabdominal bilomas developed in 18 patients. Fifteen of the patients had a solitary biloma, and the other patients each had two separate concurrent bilomas. The major cause of biloma formation was postoperative bile leakage from a bile duct after laparotomy done primarily for surgery on the gallbladder or liver. Maximal diameter of the bilomas in the transaxial plane ranged from 2 to 19 cm. The contours of the bilomas were configured by the diaphragm, mesenteries, liver, and other abdominal organs. On CT and sonography, the bilomas were invariably well demarcated, but most did not have an identifiable capsule. In 19 bile collections, the CT numbers were less than 20 H. The combination of the clinical history, the location, and the CT appearance of the lesion led to the correct diagnosis in each case. Percutaneous drainage was an effective form of therapy that often eliminated the need for surgical drainage.

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

    2013-11-01

    Desmoid tumors are currently the main cause of morbidity and mortality in patients with familial adenomatous polyposis. More than 10% of these patients will develop these tumors during their lifetime and more than a third will suffer their consequences. The main risk factors for their development are female sex and abdominal surgery. The most frequent localization is intraabdominal. The therapeutic approach to these tumors has changed, and the surgical treatment of choice is currently the subject of debate. If a watch and wait approach is adopted, more than 50% of tumors will prove to be indolent. Therefore, the therapeutic strategy should be based on clinical presentation and should be decided by a multidisciplinary team working in a center with experience of these tumors. The present article proposes a prognostic classification to guide the therapeutic approach. Copyright © 2012 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

    Full Text Available We describe here an example of structural equation modeling in epidemiology. The association between birth weight and adiposity in early adult life, adjusted for the number of cigarettes smoked during pregnancy and socioeconomic status at birth, was evaluated. Data involving 2,063 adults from the 1978/1979 Ribeirão Preto cohort study were used. Adiposity was measured by body mass index (BMI, waist circumference (WC and the sum of triceps and subscapular skinfolds (STSS. Models were submitted to maximum likelihood estimation, separately for men and women. Birth weight had a small and significant effect on adiposity in men (standardized coefficient, SC = 0.08 and women (SC = 0.09. Smoking during pregnancy did not influence adiposity in men (SC = 0.004, but its effect was marginally significant in women (SC = 0.07; P = 0.056. Socioeconomic status at birth had a small and positive effect on adiposity in men (SC = 0.08 and a moderate and negative effect in women (SC = -0.16. In this young adult population, BMI, WC and STSS used alone or in combination were valid estimators of body adiposity.O objetivo desse artigo é apresentar um exemplo da modelagem com equações estruturais.

  10. Intra-abdominal hypertension in acute pancreatitis.

    Science.gov (United States)

    De Waele, Jan J; Leppäniemi, Ari K

    2009-06-01

    The incidence of intra-abdominal hypertension (IAH) in patients with severe acute pancreatitis (SAP) is approximately 60-80%. It is usually an early phenomenon, partly related to the effects of the inflammatory process, causing retroperitoneal edema, fluid collections, ascites, and ileus, and partly iatrogenic, resulting from aggressive fluid resuscitation. It also can manifest at a later stage, often associated with local pancreatic complications. IAH is associated with impaired organ dysfunction, especially of the cardiovascular, respiratory, and renal systems. Using current definitions, the incidence of the clinical manifestation, abdominal compartment syndrome (ACS), has been reported as 27% in the largest study so far. Despite several intervention options, the mortality in patients developing ACS remains high: 50-75%. Prevention with judicious use of crystalloids is important, and nonsurgical interventions, such as nasogastric decompression, short-term use of neuromuscular blockers, removal of fluid by extracorporeal techniques, and percutaneous drainage of ascites should be instituted early. The indications for surgical decompression are still not clearly defined, but undoubtedly some patients benefit from it. It can be achieved with full-thickness laparostomy (midline or transverse subcostal) or through a subcutaneous linea alba fasciotomy. Despite the improvement in physiological variables and significant decrease in IAP, the effects of surgical decompression on organ function and outcome are less clear. Because of the significant morbidity associated with surgical decompression and the management of the ensuing open abdomen, more research is needed to define better the appropriate indications and techniques for surgical intervention.

    Full Text Available Intraabdominal schwannomas, which occur quite rarely, are usually benign tumors. They are often discovered coincidentally when abdominal scans are performed for other reasons. We also coincidentally detected an intraabdominal schwannoma in addition to primary hyperparathyroidism related to a parathyroid adenoma and a gastric adenoma which caused partial pyloric obstruction in a 69-year-old female patient who was admitted to our emergency room with vomiting while we were further investigating hypercalcemia that was found during laboratory workup. It is rare to diagnose multiple tumors concurrently in a single patient which are components of certain neuroendocrine syndromes themselves. It is more interesting to see a rare tumor such as intraabdominal schwannoma coexisting with a parathyroid adenoma that can be a component of multiple endocrine neoplasia syndromes. In the literature, there are few case reports of the coexistence of intraabdominal schwannomas with adenocarcinoma of the gastrointestinal tract. Here, we present an unusual case of intraabdominal schwannoma coexisting with parathyroid adenoma and gastic adenocarcinoma, all diagnosed in a single patient. To our best knowledge, this is the first case report of such a rare coexistence which makes it rather interesting.

    Full Text Available Abstract Complicated intra-abdominal infections are frequently associated with poor prognoses and high morbidity and mortality rates. Despite advances in diagnosis, surgery, and antimicrobial therapy, mortality rates associated with complicated intra-abdominal infections remain exceedingly high. In order to describe the clinical, microbiological, and management-related profiles of both community-acquired and healthcare-acquired complicated intra-abdominal infections (IAIs, the World Society of Emergency Surgery (WSES, in collaboration with the Surgical Infections Society of Europe (SIS-E and other prominent European surgical societies, has designed the CIAO study. The CIAO study is a multicenter, observational study and will be carried out in various surgical departments throughout Europe. The study will include patients undergoing surgery or interventional drainage for complicated IAI.

  13. Intraabdominal abscess caused by Stenotrophomonas maltophilia: A case report

    Directory of Open Access Journals (Sweden)

    Toyomitsu Sawai

    Full Text Available Introduction: Stenotrophomonas maltophilia usually causes nosocomial infections, but intraabdominal abscesses or organ/space surgical site infection (SSI secondary to this organism has been rarely reported. Here, we reported a rare case of SSI that presented as intraabdominal abscess caused by S. maltophilia. Presentation of case: A 68-year-old woman presented to our hospital with transverse colon cancer. Further work up with abdominal computed tomography (CT revealed left renal cell carcinoma. Transverse colon resection and left kidney partial resection were performed. On post-operative day 10, she started to have fever at 38 °C and repeat abdominal CT showed intraabdominal abscess. Empiric treatment with piperacillin/tazobactam (TAZ/PIPC was initiated. However, fever persisted and the abscess size did not change despite 10 days of antibiotic. On post-operative day 20, drainage of intraabdominal abscess was performed. TAZ/PIPC was then shifted to meropenem (MEPM. After two days, S. maltophilia was identified in the culture of the abscess, and MEPM was shifted to minocycline (MINO. Fever disappeared after 7 days of treatment and abdominal CT after 14 days showed almost complete resolution of the abscess. Discussion: S. maltophilia is a multi-drug resistant, aerobic, non-glucose fermenting, non-sporulating, Gram-negative bacillus. S. maltophilia may cause a variety of infections, but intraabdominal abscesses as a manifestation of SSI due to this organism is relative rare. Conclusion: Although usually a non-pathogenic organism or colonizer, S. maltophilia can cause organ/space SSI in an immunocompromised host. Therefore, clinicians should be aware of the possibility that S. maltophilia may cause organ/space SSI. Keywords: Stenotrophomonas maltophilia, Intraabdominal abscess, Surgical site infections

    Procalcitonin is a quite specific biomarker of infection and in recent years has shown its superiority to others markers of inflammation, such as C-reactive protein, for the diagnosis and monitoring of a variety of infections. For this reason, several researchers have studied the potential role of procalcitonin for diagnosis and management of these infections. Intra-abdominal infections are a heterogeneous group of infections that, sometimes, pose difficult challenges to physicians. The published studies have produced mixed results, leading to controversy on the utility of this marker in intra-abdominal infections. This review summarizes these data and discuss the utility of procalcitonin in several intra abdominal infections, including postoperative infections.

    Intra-abdominal infections are a common problem for the general surgeon and major sources of morbidity and mortality in the intensive care unit. Some of these patients present with peritonitis that can rapidly progress to septic shock. The basic principles of care include prompt resuscitation, antibiotics, and source control. This article will use a detailed case study to outline the management of a patient with severe intra-abdominal infection from diverticulitis from initial resuscitation to reconstruction. Components of the Surviving Sepsis Campaign as they pertain to surgical patients are discussed and updated, and the concept of damage control general surgery is applied. Copyright © 2012.

    Full Text Available Abstract Purpose Appendicitis is the most common abdominal inflammatory process in children which were sometimes followed by complications including intra-abdominal abscess. This later needs classically a surgical drainage. We evaluated the efficacy of antibiotic treatment and surgical drainage. Methods Hospital records of children treated in our unit for intra-abdominal post appendectomy abscesses over a 6 years period were reviewed retrospectively. Results This study investigates a series of 14 children from 2 to 13 years of age with one or many abscesses after appendectomy, treated between 2002 and 2007. Seven underwent surgery and the others were treated with triple antibiotherapy. The two groups were comparable. For the 7 patients who receive medical treatment alone, it was considered efficient in 6 cases (85% with clinical, biological and radiological recovery of the abscess. There was one failure (14%. The duration of hospitalization from the day of diagnosis of intra-abdominal abscess was approximately 10.28 days (range 7 to 14 days. In the other group, the efficacy of treatment was considered satisfactory in all cases. The duration of hospitalization was about 13 days (range: 9 to 20. Conclusion Compared to surgical drainage, antibiotic management of intra-abdominal abscesses was a no invasive treatment with shorter hospitalization.

MÉTODOS: Estudio transversal descriptivo en 639 estudiantes de 18 a 29 años representativos de las universidades de Valencia, España, en el curso 2005-2006. La práctica de actividad física se evaluó mediante el inventario de conductas de salud en escolares. Se aplicaron las escalas de competencia física percibida, autoestima, satisfacción con la vida y vitalidad subjetiva. La adiposidad corporal se expresó mediante el porcentaje de masa grasa (PMG. Se elaboró un modelo teórico con las seis variables medidas. RESULTADOS: El nivel de actividad física de los participantes era moderado, se percibían físicamente competentes, tenían una alta autoestima, se encontraban satisfechos con su vida y se sentían con alta vitalidad. La actividad física se relacionó negativamente con el PMG tanto en los varones como en las mujeres; el PMG se asoció negativamente con la percepción de competencia física; y la competencia física percibida se asoció positivamente con la autoestima, la satisfacción con la vida y la vitalidad subjetiva. El efecto de la práctica de actividad física sobre la competencia percibida estaba mediado parcialmente por el PMG en los varones; en las mujeres, la práctica de actividad física se relacionó directamente tanto con el PMG como con la percepción de competencia, sin la mediación del PMG. CONCLUSIONES: El aumento de la actividad física tiene un gran valor para la salud pública, ya que además de contribuir a tener menos grasa corporal, aumenta el bienestar psicológico y mejora la autopercepción.OBJECTIVE: To determine, through the use of a structural equation model, the relationships that exist between physical activity, body

    Compared to other infections, intraabdominal infections include wide spectrum of infections of various severity, have different ethiology, which is frequently polymicrobial, show different microbiological results, which are difficult to interpret. The role of surgical intervention is essential. Intraabdominal infections are common causes of morbidity and mortality. Their prognosis is significantly improved with early and exact diagnosis, appropriate surgical or radiological intervention and timely effective antimicrobial therapy. Practitioners may choose between older or more modern antibiotics, between monotherapy or combination therapy, however, they should also consider clinical condition of the patient, the antibiotic's spectrum of activity, the treatment timing and its duration, the dose and dosing scheme of the particular antimicrobials. Furthermore, antimicrobial therapy should be used with caution, with the aim to prevent development of antimicrobial resistence. Inappropriate choice of antimicrobials in initial empiric therapy results in relapsing infections, surgical intervention and prolongation of hospitalization, and even death rates reflect adequate and timely empiric therapy.

    CT diagnosis of intraabdominal abscess was confirmed in 18 patients by laparatomy and in two by autopsy. In CT abscess is characterized by an expansive soft-tissue lesion with different density values, mostly with a central fluid collection and a thickened wall. The peripheral inflammatory reaction leads to obliteration of fat planes surrounding the adjacent organs. Further symptomes are constrast enhancement of the wall and extraluminal gas collection. The combination of all these signs together with a suitable history and clinical findings allow a reliable diagnosis of abscess formation. When only isolated signs are found, differentiation from tumor, pseudocyst or hematoma may be difficult. (orig.) [de

  19. A user's guide to intra-abdominal pressure measurement.

    2015-01-01

    The intra-abdominal pressure (IAP) measurement is a key to diagnosing and managing critically ill medical and surgical patients. There are an increasing number of techniques that allow us to measure the IAP at the bedside. This paper reviews these techniques. IAP should be measured at end-expiration, with the patient in the supine position and ensuring that there is no abdominal muscle activity. The intravesicular IAP measurement is convenient and considered the gold standard. The level where the mid-axillary line crosses the iliac crest is the recommended zero reference for the transvesicular IAP measurement; moreover, marking this level on the patient increases reproducibility. Protocols for IAP measurement should be developed for each ICU based on the locally available tools and equipment. IAP measurement techniques are safe, reproducible and accurate and do not increase the risk of urinary tract infection. Continuous IAP measurement may offer benefits in specific situations in the future. In conclusion, the IAP measurement is a reliable and essential adjunct to the management of patients at risk of intra-abdominal hypertension.

    Full Text Available Atualmente, a obesidade pode ser classificada como uma pandemia e suas conseqüências vão desde o diabetes mellitus até a doença cardíaca. Tanto fatores genéticos como ambientais contribuem para isso, porém, em humanos, o componente genético ainda é pouco definido. Com a clonagem do gene ob de ratos e do seu receptor, foi descoberta a leptina, o "hormônio da saciedade". A leptina é secretada, principalmente, pelo tecido adiposo e reflete a quantidade de gordura depositada no tecido adiposo de um indivíduo. Entretanto, diversos fatores influenciam sua expressão e síntese, tais como jejum, atividade simpática, exercício físico e alterações no balanço energético. Os efeitos da atividade física aeróbia sobre esse hormônio ainda não estão muito claros, visto que existem muitas contradições na literatura sobre sua possível ação na regulação da leptina. Estudos transversais sugerem que as concentrações plasmáticas de leptina não são alteradas após uma sessão de exercício aeróbio. Entretanto, se o esforço físico for extremo, como em uma ultramaratona, na qual há um balanço energético negativo, induzido pela atividade física extenuante, ocorre diminuição dessas concentrações. Além disso, exercícios de longa duração (> 60 min parecem estar associados à diminuição tardia das concentrações de leptina, aproximadamente 48h após a atividade, provavelmente em função de um possível desequilíbrio energético. Em relação aos estudos longitudinais, após o treinamento aeróbio, alguns autores não observam alterações na leptina plasmática, outros encontram alterações em função apenas das alterações da adiposidade e, por fim, alguns estudos observam diminuição da concentração plasmática e/ou expressão de leptina, independentemente de alterações da massa gorda. Tal fato sugere que haja outro, ou outros, fatores, além do conteúdo de gordura corporal, que modulam a diminuição das

    Full Text Available We report a case of intra-abdominal testicular tumor in a 36-year-old married lady presenting with chief complaints of primary amenorrhea. The patient was later diagnosed with testicular feminization syndrome, a form of male pseudohermaphroditism. This testicular tumor was histologically proven as seminoma. Due to rarity, imaging findings in patients with testicular feminization syndrome and intraabdominal testicular tumor have been poorly documented. So far, only one case report had described the combined role of CT and MR imaging in intraabdominal testicular sex-cord stromal tumor. To our knowledge, this case is first to document USG and MR imaging in addition to MR spectroscopy features in intraabdominal testicular seminoma.

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

    Risk for intraabdominal abscess (IAA) after laparoscopic appendectomy (LA) remains controversial. A 2008 Cochrane Review suggests almost a threefold increase in the incidence of IAA after LA compared with open appendectomy (OA). The authors conducted a retrospective chart review of all appendicitis patients 18 years and older undergoing appendectomy from 1996 to 2007 at one military treatment facility and one civilian hospital in Hawaii. Data collection included demographics, procedure, presence of complicated appendicitis (defined as perforated or gangrenous appendicitis at surgical or pathologic assessment), and presence of postoperative IAA on computed axial tomography (CAT) scan. The review identified 2,464 patients with appendicitis. A total of 1,924 LAs (78%) and 540 OAs (22%) were performed. The comparison of laparoscopic and open appendectomies showed no significant differences in the number of postoperative abscesses (2.2% vs 1.9%; p = 0.74). The patients with a diagnosis of complicated appendicitis were significantly associated with a higher incidence of postoperative abscess formation (67% vs 25%; p abscess in patients with complicated appendicitis could be found between LA and OA (5.9% vs 4.1%; p = 0.44). No significant difference in the occurrence of IAA after LA versus OA was found. The patients with complicated appendicitis experienced a greater number of IAA than the patients with uncomplicated appendicitis.

    Percutaneous catheter drainage has been reported to be an effective method in the management of selected patients with abscess and fluid collection. Its high success rate and relatively low complications make the procedure an alternative to surgery in the individual cases. During past two years percutaneous catheter drainage in 25 patients with intraabdominal abscesses and fluid collection was performed at the Department of Radiology, Yonsei University College of medicine. Here the technique and author's results were summarized. 1. The total 25 patients who had percutaneous catheter drainage are 10 liver abscesses, 3 subphrenic, one subhepatic, 4 renal and perirenal, 2 pelvic, one psoas, one anterior pararenal fluid from acute pancreatitis, one pancreas pseudocyst and 2 malignant tumor necrosis. 2. The modified Seldinger technique used for all cases of abscess and fluid drainage under guidance of ultrasound scan. The used catheters were 10F. Pigtail and 14F. Malecot (Cook c/o) catheters. 3. The abscesses and fluid of 17 patients among 25 were cured by the percutaneous catheter drainage and 4 patients were clinically improved. The catheter drainage was failed in 2 patients and 3 complication were developed. 4. The success rate of this procedure was 91.3%, failure rate was 8.7% and complication rate was 12%.

  12. Handlebar hernia: an uncommon cause of intra-abdominal lesions.

    Science.gov (United States)

    Schoofs, N; Van der Speeten, K

    2013-01-01

    A traumatic abdominal wall hernia (TAWH) is an uncommon complication of abdominal trauma. Handlebar hernia is an even rarer type of traumatic abdominal wall hernia, with only 33 previously reported cases in literature. It is caused by a local trauma with a handlebar-like object which is not sharp enough to penetrate the elastic skin, but has sufficient focused force to breach the muscle and fascia of the abdominal wall. A high index of clinical suspicion for associated intra-abdominal lesions in patients with traumatic abdominal wall hernia is warranted. This may not only influence the immediate treatment of the abdominal hernia but also the type and timing of mesh repair to be performed. Early repair is mandatory to avoid complications. The choice for primary repair versus mesh repair will be discussed according to the size of the hernia and the amount of tissue destruction by the trauma. The type of mesh used for the repair will be determined by presence or absence of contamination in the abdomen.

    It is known that intra-abdominal hypertension has high morbidity in acute pancreatitis and has detrimental effects on patients. For third trimester pregnancy complicated by acute pancreatitis, the intra-abdominal pressure may have its own characteristic. This article will discuss this clinical scenario. This observational study in a cohort group was performed in the surgical intensive care unit of a tertiary hospital. Medical records were reviewed from each acute pancreatitis exactly in third trimester pregnancy. The main statistical methods were Mann-Whitney U test and bivariate Pearson correlation analysis. During the study interval, there were totally 17 pregnancies complicated by acute pancreatitis in the third trimester. All cases with moderate or severe acute pancreatitis had intra-abdominal hypertension of mean value of 16.7 mm Hg (range, 12.9-22.0 mm Hg). The intra-abdominal pressure had significant correlation with APACHE II score (r = 0.7456, p = 0.0006), while a negative correlation was showed with the umbilical artery pH value and with 1-min Apgar score (r = -0.8232, p = 0.0005; r = -0.7465, p = 0.0034; respectively). The intra-abdominal pressure of those with live infants was lower than that of those with dead ones (13.78 ± 2.554 vs. 19.84 ± 1.695, p = 0.0019). The incidence of intra-abdominal hypertension seems higher in moderate or severe acute pancreatitis in third trimester pregnancy than the non-pregnant cases but there's no significance in this study. Acute elevated intra-abdominal pressure accounts for great association with mother's serious scenario and fetal mortality.

    Objective To evaluate the frequency of intra-abdominal hypertension in major burn patients and its association with the occurrence of acute kidney injury. Methods This was a prospective cohort study of a population of burn patients hospitalized in a specialized intensive care unit. A convenience sample was taken of adult patients hospitalized in the period from 1 August 2015 to 31 October 2016. Clinical and burn data were collected, and serial intra-abdominal pressure measurements taken. The significance level used was 5%. Results A total of 46 patients were analyzed. Of these, 38 patients developed intra-abdominal hypertension (82.6%). The median increase in intra-abdominal pressure was 15.0mmHg (interquartile range: 12.0 to 19.0). Thirty-two patients (69.9%) developed acute kidney injury. The median time to development of acute kidney injury was 3 days (interquartile range: 1 - 7). The individual analysis of risk factors for acute kidney injury indicated an association with intra-abdominal hypertension (p = 0.041), use of glycopeptides (p = 0.001), use of vasopressors (p = 0.001) and use of mechanical ventilation (p = 0.006). Acute kidney injury was demonstrated to have an association with increased 30-day mortality (log-rank, p = 0.009). Conclusion Intra-abdominal hypertension occurred in most patients, predominantly in grades I and II. The identified risk factors for the occurrence of acute kidney injury were intra-abdominal hypertension and use of glycopeptides, vasopressors and mechanical ventilation. Acute kidney injury was associated with increased 30-day mortality. PMID:29513889

    Abstract Background: Low serum albumin concentration is a predictor of failure of source control for intra-abdominal infection. However, data on dynamics of albumin synthesis in these patients and to what extent these changes contribute to hypoalbuminemia are relatively scarce. We investigated in a group of patients with gastrointestinal fistula the dynamic response of liver albumin synthesis to intra-abdominal abscess and how these related to hypoalbuminemia and circulating endocrine hormone profiles. Methods: Eight gastrointestinal fistula patients scheduled to undergo percutaneous abscess sump drainage were enrolled prospectively to measure albumin synthesis rates at different stages of the inflammatory response (immediately after diagnosis and 7 d following sump drainage when clinical signs of intra-abdominal sepsis had been eradicated). Eight age-, sex-, and body mass index–matched intestinal fistula patients were studied as control patients. Consecutive arterial blood samples were drawn during a primed-constant infusion (priming dose: 4 micromol·kg−1, infusion rate: 6 micromol·kg−1·min−1) to determine the incorporation rate of L-[ring-2H5]-phenylalanine directly into plasma albumin using gas chromatography/mass spectrometry analysis. Results: Patients suffering from intra-abdominal infection had reduced plasma albumin and total plasma protein concentrations, compared with control patients. Albumin fractional synthesis rates in patients with intra-abdominal abscess were decreased, compared with those in the control group. When the source of infection was removed, albumin synthesis rates returned to control values, whereas albumin concentrations did not differ significantly from the corresponding concentrations in control subjects and patients with intra-abdominal abscess. Conclusion: Despite nutritional intervention, albumin synthesis rate is decreased in intestinal fistula patients with intra-abdominal abscess; albumin synthesis returns to

    The epidemiology of pediatric blunt intraabdominal arterial injury is ill defined. We analyzed a multiinstitutional trauma database to better define injury patterns and predictors of outcome. The American College of Surgeons National Trauma Database was evaluated for all patients younger than 16 years with blunt intraabdominal arterial injury from 2000 to 2004. Injury distribution, operative treatment, and variables associated with mortality were considered. One hundred twelve intraabdominal arterial injuries were identified in 103 pediatric blunt trauma patients. Single arterial injury (92.2%) occurred most frequently: renal (36.9%), mesenteric (24.3%), and iliac (23.3%). Associated injuries were present in 96.1% of patients (abdominal visceral, 75.7%; major extraabdominal skeletal/visceral, 77.7%). Arterial control was obtained operatively (n = 46, 44.7%) or by endovascular means (n = 6, 5.8%) in 52 patients. Overall mortality was 15.5%. Increased mortality was associated with multiple arterial injuries (P = .049), intraabdominal venous injury (P = .011), head injury (P = .05), Glasgow Coma Score less than 8 (P cardiac arrest (P Trauma Score [P Injury Severity Score [P = .001], and TRISS [P = .002]). Blunt intraabdominal arterial injury in children usually affects a single vessel. Associated injuries appear to be nearly universal. The high mortality rate is influenced by serious associated injuries and is reflected by overall injury severity scores.

    Patients with Parkinson's disease (PD) lose body weight primarily due to decreased body fat mass. The purpose of this study was to elucidate possible factors related to reduction in the intra-abdominal fat mass of 6-hydroxydopamine (6-OHDA)-treated rats, which are frequently used as an animal model for PD. Sham-operated (NPD: n = 4) and unilaterally 6-OHDA-injected (PD: n = 4) 14-wk-old male Sprague-Dawley rats were fed a relatively high-fat diet for 2 wk, during which food intake and body weight were measured. After the 2-wk feeding period, intra-abdominal fat was dissected out and weighed. Carbohydrate and fat absorption-related gene expressions in the jejunum and serum insulin and glucose concentrations were analyzed. Although final body weights did not differ, total intra-abdominal fat weight, expressed relative to body weight, was significantly lower in the PD group than in the NPD group (P NPD rats (P < 0.05). PD model rats displayed loss of intra-abdominal fat, similar to the progressive loss of fat in PD patients. Our results provide preliminary evidence that reduced lipogenesis due to lower insulin levels, rather than impaired digestion/absorption, might have been involved in this decrease in intra-abdominal fat mass.

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

    LENUS (Irish Health Repository)

    Sugrue, Michael

    2012-01-31

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

    Full Text Available Introduction. Early assessment of the severity and etiology of acute pancreatitis is very important for further treatment procedures. The aim of the study was to investigate the association between intra-abdominal pressure (IAP and procalcitonin as an indicator of severity of acute pancreatitis. Method. The IAP is measured every 12 hours through the urinary catheter placed in the bladder, in 65 patients with acute pancreatitis. Procalcitonin is measured within 24 hours of receipt of the patient, after 48 hours and after 78 hours. These values of procalcitonin and IAP were compared to each other and in relation to the Acute Physiology, Age and Chronic Health Evaluation II (APACHE II scoring system. Patients with APACHE II score > 8 are defined with moderate and severe acute pancreatitis. Results. The values of IAP (18,1 ± 4,5 mmHg vs 8,9 ± 2,67 mmHg; p = 0,01 , procalcitonin (15,43 + 2,25 ng/ml vs 3,14 + 1,12 ng/ml; p =0,031 and APACHE II scoring system (17,3 ± 6,24 vs 6,5 ± 1,0; p = 0,013 were significantly higher in patients with moderate and severe acute pancreatitis. The increase in the value of IAP was accompanied by an increase in the value of procalcitonin (r = 0,581, p = 0,01. The sensitivity in the prediction of severe acute pancreatitis after 24 hours of receiving the patient is 91,7% for the IAP, 87,8% for procalcitonin and 84,9% for APACHE II scoring system. Conclusion. The increase in the value of the IAP is accompanied by an increase in the values of procalcitonin, also patients with higher values of APACHE II scoring sys­tem have higher values of IAP and procalcitonin. The values of IAP and procalcitonin can be used as markers of acute pancreatitis severity.

    BACKGROUND: Intraabdominal infections are caused mainly by anastomotic leaks and represent a serious complication. Diagnosis is usually made when patients become critically ill. Though inflammatory markers, including C-reactive protein (CRP) and white blood count (WBC), may contribute to an early...... diagnosis, their clinical roles remain unclear. The diagnostic accuracy of continuous tests depends on the choice of cut-off values. We analyzed the diagnostic accuracy of serial CRP and WBC measurements to detect infectious complications after colorectal resections. PATIENTS AND METHODS: The CRP and WBC...... of CRP was similar. CONCLUSION: Serial CRP measurements are helpful for detecting intraabdominal infections after colorectal resection. Persistently elevated CRP values after POD 3 should be investigated for intraabdominal infection....

    Full Text Available O chá é uma das bebidas mais consumidas no mundo, vem sendo utilizado pela população como coadjuvante no tratamento da redução de peso, uma vez que aumenta a termogênese e em muitos casos promove a saciedade. O objetivo deste trabalho foi mostrar como as catequinas do chá verde auxiliam no tratamento da obesidade. Foram realizadas buscas por artigos científicos nas bases de dados Science Direct, Google Acadêmico, Scielo, BVS, Medline e Wilson. Os artigos escolhidos foram publicados no período de 2000 a 2014. Observa-se que o tratamento da obesidade envolve necessariamente a reeducação alimentar, o aumento da atividade física e eventualmente, o uso de algumas medicações auxiliares. Outra alternativa, é o uso de fitoterápicos como por exemplo o chá verde. Estudos têm mostrado que este chá, que é obtido pela infusão da erva Camellia sinensis é rico em catequinas, responsáveis na redução de peso, pois promovem a termogênese e aumentam a saciedade. A epigalocatequina (EGCG, é a catequina mais abundante e mais forte do chá verde. É importante ressaltar que o chá usado de maneira inadequada pode causar hepatotoxicidade. O uso do chá associado a um plano alimentar equilibrado pode trazer benefícios à saúde além da perda de peso. Porém os estudos ainda não são conclusivos, sendo necessários mais estudos para que possa confirmar a eficácia do chá verde na obesidade e a quantidade a ser utilizada. Entretanto, a reeducação alimentar, exercício físico continuam sendo os fatores mais importantes no tratamento da obesidade, Onde o consumo de chá verde deve está associado a uma alimentação saudável.

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

    2010-11-01

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

    and vascular cell adhesion molecule 1) and the adhesion assay, a functional measure of endothelial activation, were elevated at 72 hours and 120 hours in mice that underwent CLP versus sham-operations (all at P <0.05). Using a combination of existing murine models for atherosclerosis and sepsis, we found that CLP, a model of intra-abdominal sepsis, accelerates atheroma development. Accelerated atheroma burden was associated with prolonged systemic, endothelial and intimal inflammation and was not explained by ongoing infection. These findings support observations in humans and demonstrate the feasibility of a long-term follow-up murine model of sepsis.

    2009-02-01

    Full Text Available OBJECTIVE: The aim of this study was to quantify the interaction between increased intra-abdominal pressure and Positive-End Expiratory Pressure. METHODS: In 30 mechanically ventilated ICU patients with a fixed tidal volume, respiratory system plateau and abdominal pressure were measured at a Positive-End Expiratory Pressure level of zero and 10 cm H2O. The measurements were repeated after placing a 5 kg weight on the patients' belly. RESULTS: After the addition of 5 kg to the patients' belly at zero Positive-End Expiratory Pressure, both intra-abdominal pressure (p<0.001 and plateau pressures (p=0.005 increased significantly. Increasing the Positive-End Expiratory Pressure levels from zero to 10 cm H2O without weight on the belly did not result in any increase in intra-abdominal pressure (p=0.165. However, plateau pressures increased significantly (p< 0.001. Increasing Positive-End Expiratory Pressure from zero to 10 cm H2O and adding 5 kg to the belly increased intra-abdominal pressure from 8.7 to 16.8 (p<0.001 and plateau pressure from 18.26 to 27.2 (p<0.001. Maintaining Positive-End Expiratory Pressure at 10 cm H2O and placing 5 kg on the belly increased intra-abdominal pressure from 12.3 +/- 1.7 to 16.8 +/- 1.7 (p<0.001 but did not increase plateau pressure (26.6+/-1.2 to 27.2 +/-1.1 -p=0.83. CONCLUSIONS: The addition of a 5kg weight onto the abdomen significantly increased both IAP and the airway plateau pressure, confirming that intra-abdominal hypertension elevates the plateau pressure. However, plateau pressure alone cannot be considered a good indicator for the detection of elevated intra-abdominal pressure in patients under mechanical ventilation using PEEP. In these patients, the intra-abdominal pressure must also be measured.

    Full Text Available Objective  To observe the effect of vacuum sealing drainage (VSD assisted intra-abdominal volume increment (IAVI technique on the liver in the treatment of intra-abdominal hypertension (IAH following hemorrhagic shock resuscitation in pigs. Methods  Twelve healthy mini-pigs (Bama, Guangxi were selected for bloodletting from the femoral artery to reproduce hemorrhagic shock model (mean arterial blood pressure, 50mmHg, 1h, and IAH model was successfully reproduced in eight pigs by partial occlusion of portal vein. The eight pigs were randomly divided into the intra-abdominal volume increment treatment (IT group (n=4 and sham operation control (SC group (n=4. Vesical pressure (VP and inferior vena cava pressure (IVCP were observed before shock, 2h after IAH, and 22h after IAVI treatment. Aspartate aminotransferase (AST and alanine aminotransferase (ALT were measured. In addition, the ratio of the abdominal anteroposterior diameter to the transverse diameter was assessed, and the liver CT values were measured after enhanced CT scanning. The pigs were sacrificed 26h after operation. Liver specimens were collected to measure the ratio of wet weight to dry weight and pathological examination. Results  The VP in 8 IAH pigs was 21.16±4.63mmHg. The ratio of abdominal anteroposterior diameter to the transverse diameter increased remarkably 2h after IAH compared with that before shock (1.22±1.41 vs 0.96±0.08, PPvs 42.73±4.92HU, PPPvs 5.14±0.71, PConclusions  The established model could better reproduce the symptoms of IAH after hemorrhagic shock and fluid resuscitation, accompanied by liver damage. IAVI helps to relieve liver functional disturbance after IAH, which is related to decreased intra-abdominal pressure and hypoxia-ischemia of the liver.

    The purpose of this study was to evaluate the presence and localization of intraabdominal adhesions using functional cine magnetic resonance imaging (MRI) and to correlate the MR findings with intraoperative results. In a retrospective study, patients who had undergone previous abdominal surgery with suspected intraabdominal adhesions were examined. A true fast imaging with steady state precession sequence in transverse/sagittal orientation was used for a section-by-section dynamic depiction of visceral slide on a 1.5-Tesla system. After MRI, all patients underwent anew surgery. A nine-segment abdominal map was used to document the location and type of the adhesions. The intraoperative results were taken as standard of reference. Ninety patients were enrolled. During surgery 71 adhesions were detected, MRI depicted 68 intraabdominal adhesions. The most common type of adhesion in MRI was found between the anterior abdominal wall and small bowel loops (n = 22, 32.5%) and between small bowel loops and pelvic organs (n = 14, 20.6%). Comparing MRI with the intraoperative findings, sensitivity varied between 31 and 75% with a varying specificity between 65 and 92% in the different segments leading to an overall MRI accuracy of 89%. Functional cine MRI proved to be a useful examination technique for the identification of intraabdominal adhesions in patients with acute or chronic pain and corresponding clinical findings providing accurate results. However, no differentiation for symptomatic versus asymptomatic adhesions is possible. (orig.)

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

    Full Text Available In accordance with the trans-lamina cribrosa pressure difference theory, decreasing the trans-lamina cribrosa pressure difference can relieve glaucomatous optic neuropathy. Increased intracranial pressure can also reduce optic nerve damage in glaucoma patients, and a safe, effective and noninvasive way to achieve this is by increasing the intra-abdominal pressure. The purpose of this study was to observe the changes in orbital subarachnoid space width and intraocular pressure at elevated intra-abdominal pressure. An inflatable abdominal belt was tied to each of 15 healthy volunteers, aged 22–30 years (12 females and 3 males, at the navel level, without applying pressure to the abdomen, before they laid in the magnetic resonance imaging machine. The baseline orbital subarachnoid space width around the optic nerve was measured by magnetic resonance imaging at 1, 3, 9, and 15 mm behind the globe. The abdominal belt was inflated to increase the pressure to 40 mmHg (1 mmHg = 0.133 kPa, then the orbital subarachnoid space width was measured every 10 minutes for 2 hours. After removal of the pressure, the measurement was repeated 10 and 20 minutes later. In a separate trial, the intraocular pressure was measured for all the subjects at the same time points, before, during and after elevated intra-abdominal pressure. Results showed that the baseline mean orbital subarachnoid space width was 0.88 ± 0.1 mm (range: 0.77–1.05 mm, 0.77 ± 0.11 mm (range: 0.60–0.94 mm, 0.70 ± 0.08 mm (range: 0.62–0.80 mm, and 0.68 ± 0.08 mm (range: 0.57–0.77 mm at 1, 3, 9, and 15 mm behind the globe, respectively.

    2016-06-01

    Full Text Available Background: Intra-abdominal adhesions are a very common complication following abdominal surgery. Our previous studies have demonstrated that the inhibition of inflammation at the sites of peritoneal injury can prevent the formation of intra-abdominal adhesions. Resveratrol is a natural extract with a broad range of anti-inflammatory effects. Therefore, we propose that resveratrol can reduce the formation of intra-abdominal adhesions after surgery. The aim of this study was to investigate the effect of resveratrol on intra-abdominal adhesion prevention in a rat model with surgery-induced peritoneal adhesions. Materials and Methods: The cecum wall and its opposite parietal peritoneum were abraded following laparotomy to induce intra-abdominal adhesion formation. Varying doses of resveratrol were administered to the animals. On the eighth day after surgery, the adhesion score was assessed using a visual scoring system. Picrosirius red staining and a hydroxyproline assay were used to assess the amount of collagen deposition in the adhesion tissues. The levels of serum interleukin-6 (IL-6, tumor necrosis factor (TNF-α, and transforming growth factor beta-1 (TGF-β1 were determined by an enzyme-linked immunosorbent assay (ELISA. Western blotting was performed to determine the protein expression of TGF-β1, fibrinogen, and α-smooth muscle actin (α-SMA in rat peritoneal adhesion tissue. Real-time RT-PCR was performed to quantify the mRNA expression of TGF-β1, fibrinogen, and α-SMA. Results: Resveratrol significantly reduced intra-abdominal adhesion formation and fibrin deposition in the rat model. Furthermore, resveratrol significantly reduced the serum levels of IL-6, TNF-α, and TGF-β1. The protein and mRNA expression of TGF-β1, fibrinogen, and α-SMA in the rat peritoneum and adhesion tissues were also down-regulated due to resveratrol intervention. Conclusion: Resveratrol can effectively prevent the formation of postoperative intra-abdominal

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

    To determine the accuracy of physical examination and ultrasonographic evaluation performed by emergency physicians in cases of blunt abdominal trauma for the early diagnosis of intraabdominal haemorrhage. In this clinical prospective study, trauma patients were evaluated with four-quadrant ultrasonography by emergency physicians after initial stabilisation and physical examination. Diagnoses based on demographic data, physical examination and emergency physician's ultrasonography were compared with the subsequent clinical course. A total of 442 patients participated in the study. The sensitivity and specificity of emergency physician's ultrasonographic examination to detect intraabdominal haemorrhage were 86 and 99%, respectively. Pre-test sensitivity and specificity of physical examination to detect intraabdominal haemorrhage were 39 and 90%, respectively. Physical examination was not a reliable method to detect intraabdominal haemorrhage in cases of blunt abdominal trauma. In contrast, abdominal ultrasonography performed by emergency physicians was a reliable diagnostic tool. Emergency physicians should be familiar with abdominal ultrasonographic examination, which should be routine in cases of blunt abdominal trauma.

  13. Common errors in the treatment of intra-abdominal infections: the irrational use of antimicrobial agents

    Full Text Available Antimicrobial resistance (AR is a global, emergent problem because an increasing numbers of serious community acquired and nosocomial infections are caused by resistant bacterial pathogens. It is a direct consequence of the excessive and irrational use of antibiotics. The use of antimicrobial agents – aimed to decrease morbidity and mortality rate related to intra-abdominal infections – is very high, often improper, in the Departments of General and Emergency Surgery and Intensive Cure Units. Source control and empiric antibiotic therapy have to be administrated as early as possible to decrease high mortality rates in patients with severe sepsis or septic shock and, in this, the general surgeon has a crucial role. Proper antimicrobial stewardship in selecting an appropriate antibiotic and optimizing its dose and duration to cure intraabdominal infections may prevent the emergence of AR and decrease costs for antibiotics.

    Kikuchi's disease is a self-limiting benign disease characterized by cervical lymphadenopathy, but it can be mistaken for malignant disease, and when involved lymph nodes are unusually located, diagnosis can be more difficult. The authors report the case of a 19-year-old man with Kikuchi's disease, who had isolated intraabdominal lymphadenopathy and increased 18-fluoro-deoxyglucose (FDG) uptake in positron emission tomography computed tomography (PET-CT). Although its incidence is extremely rare, intra-abdominal Kikuchi's disease with increased FDG uptake in PET-CT image should be considered in the differential diagnosis when constitutional symptoms mimic those of malignant lymphoma.

    Full Text Available Warfarin is an oral anticoagulant, which is commonly used in the treatment and prophylaxis of thromboembolic conditions. Bleeding is the primary adverse effect associated with warfarin. The majority of warfarin-related bleedings are spontaneous minor hemorrhages occurring in the subcutaneous or intramuscular tissues and can be treated by decreasing the dose of oral anticoagulants. However, although rare, it is possible to encounter spontaneous major bleedings with increased risk of mortality. Conservative approach is the preferred initial therapy for hemodynamically stable patients with major intra-abdominal hemorrhages that we define as the intermediate group patients. Nevertheless, surgery is required for hemodynamically unstable patients with acute abdominal pain in cases of ongoing active hemorrhage, generalized peritonitis, obstruction, acute abdomen, intestinal ischemia, and perforation. In this article, we present a rare case of acute abdomen and spontaneous intra-abdominal hemorrhage resulting from uncontrolled use of warfarin and a new classification requirement.

    Full Text Available Giant hiatal hernias, generally seen at advanced ages, can rarely cause cardiac symptoms such as dyspnea and chest pain. Here, we aimed to present a case with a large hiatal hernia that largely protruded to intrathoracic cavity and caused dyspnea, particularly at postprandial period, by compressing the left atrium and right pulmonary vein. We considered presenting this case as large hiatal hernia is a rare, intra-abdominal cause of dyspnea.

    We investigated the effects of untreated intraabdominal sepsis on polymorphonuclear leukocyte (PMN) candicidal activity. Two groups of swine were studied. Group I (n=6) underwent sham laparotomy, group II (n=7) underwent cecal ligation and incision. Untreated intraabdominal sepsis resulted in a progressive decrease in PMN candicidal activity. Concomitant rosetting and phagocytosis assays demonstrated a decrease in both the attachment and phagocytosis of Candida albicans opsonized with both normal and septic swine serum by PMNs in group II. Iodine 125-labeled swine immunoglobulin G (IgG) and fluorescein isothioalanate (FITC)-labeled swine IgG were used to investigate Fc gamma receptor ligand interactions. Scatchard analyses demonstrated a progressive decline in both the binding affinity constant and number of IgG molecules bound per PMN. Stimulation of the oxidative burst markedly reduced 125I-labeled IgG binding in both group I and group II, with a greater decrement being seen in animals with intraabdominal sepsis. Further, in group II, PMN recycling of the Fc gamma receptor to the cell surface after generation of the oxidative burst was reduced by postoperative day 4. Binding of monoclonal antibodies to Fc gamma receptor II, but not Fc gamma receptor I/III markedly reduced intracellular candicidal activity. Immunofluorescence studies revealed a homogeneous pattern of FITC-IgG uptake by nearly all group I PMNs, whereas by postoperative day 8 a substantial number of PMNs from group II failed to internalize the FITC-IgG. These studies suggest that untreated intraabdominal sepsis reduces PMN candicidal activity and that this is due, in part, to altered PMN Fc gamma receptor ligand interactions

    Full Text Available Abstract The CIAO Study (“Complicated Intra-Abdominal infection Observational” Study is a multicenter investigation performed in 68 medical institutions throughout Europe over the course of a 6-month observational period (January-June 2012. Patients with either community-acquired or healthcare-associated complicated intra-abdominal infections (IAIs were included in the study. 2,152 patients with a mean age of 53.8 years (range: 4–98 years were enrolled in the study. 46.3% of the patients were women and 53.7% were men. Intraperitoneal specimens were collected from 62.2% of the enrolled patients, and from these samples, a variety of microorganisms were collectively identified. The overall mortality rate was 7.5% (163/2.152. According to multivariate analysis of the compiled data, several criteria were found to be independent variables predictive of patient mortality, including patient age, the presence of an intestinal non-appendicular source of infection (colonic non-diverticular perforation, complicated diverticulitis, small bowel perforation, a delayed initial intervention (a delay exceeding 24 hours, sepsis and septic shock in the immediate post-operative period, and ICU admission. Given the sweeping geographical distribution of the participating medical centers, the CIAO Study gives an accurate description of the epidemiological, clinical, microbiological, and treatment profiles of complicated intra-abdominal infections (IAIs throughout Europe.

    1998-03-01

    Laparoscopic intra-abdominal ligation and removal of cryptorchid testes in horses was evaluated retrospectively in 50 horses that underwent the procedure between 1991 and 1996. Sixty-one cryptorchid testes were removed by one of the following methods; the use of 1) an endoscoping stapling and transection device, 2) an endoscopic clipping device, 3) an endoscopic ligating loop. Monopolar electrosurgery was combined with these methods to facilitate coagulation and cutting of tissue. In 8 horses, 9 testes were retained between the internal and external inguinal rings. The inguinal testes were removed by cutting the internal inguinal ring and bringing the testis back into the abdomen for removal. No attempt was made to close the internal inguinal ring. The most frequently employed and most cost effective method for laparoscopic intra-abdominal removal of cryptorchid testes in this study was the combined use of an endoscopic ligating loop and monopolar electrosurgery. One intra-operative complication (perforation of the small intestine) occurred and was dealt with successfully. One horse developed a fever attributed to upper respiratory tract infection post operatively and was treated successfully with antibiotic. Intra-abdominal ligation and transection of cryptorchid testes is an effective method for cryptorchid castration. This technique minimises the loss of insufflation, allows inspection of the cut tissue for haemorrhage and offers secure closure of the abdominal wall preventing inguinal herniation and excellent visualisation of the cryptorchid testis.

  2. Intra-abdominal hypertension in fulminant Clostridium difficile infection--an under-recognized treatable complication.

    2010-09-01

    Clostridium difficile is the most common cause of nosocomial infectious diarrhea in adults, with recent reports of increased severity and case fatality. Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are increasingly recognized and treatable complications of severe illness in medical patients, and are independent predictors of mortality. Patients with severe Clostridium difficile infection (CDI) are at increased risk for IAH and ACS. However, ACS has been only rarely described in this population. We report a case of a 61 year-old morbidly obese, chronically ill, ventilator dependent patient, who developed fulminant CDI, including progressive colonic distension, acute renal failure and intra-abdominal fluid sequestration. Her clinical course worsened abruptly, with new shock, worsening hypoxic respiratory failure, increased peak airway pressures and reduced tidal volumes. Intra-abdominal pressure was 30 mm Hg. The patient was not considered a surgical candidate, was refractory to escalating non-surgical support, and died following withdrawal of life support. Although patients with fulminant CDI share many risk factors for IAH and ACS, these conditions were rarely reported in this population and are likely under recognized, as was the case with the present patient. Increased vigilance for IAH is needed in this at-risk population.

    Pylephlebitis or septic thrombophlebitis of the portal venous system is a rare but serious complication of intra-abdominal infections which drain into the portal venous system. Its diagnosis is based on clinical suspicion and imaging tests, mainly a computed tomography scan, given the lack of specificity of the signs and symptoms. Spread of septic emboli is the major cause of morbidity and mortality. The aim of the study was to analyse patients diagnosed in our hospital. Retrospective descriptive study of patients diagnosed with pylephlebitis in our hospital. Four patients were included, 3 men and one woman. In 3 cases it was acute cholecystitis that led to the diagnosis of pylephlebitis at the same time as the intra-abdominal infection. Emergency surgery was performed in one case, whilst the other 2 were treated conservatively. Blood cultures were performed in all cases, and empirical antibiotic treatment was used. In the only case of acute appendicitis, diagnosis of pylephlebitis was achieved during the study of postoperative fever, with empirical antibiotic treatment also being started. The haematologist was requested to start the required anticoagulation therapy in all cases. Pylephlebitis is a rare complication of intra-abdominal infections that may make lead to a worse outcome. A high level of suspicion is required as well as imaging tests to make an early diagnosis and appropriate treatment. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    This study was undertaken for the purpose of describing the CT features of intra-abdominal extra-hepatic metastases from gastrointestinal stromal tumors in patients who were treated with imatinib. Eleven patients with intra-abdominal extra-hepatic metastases from gastrointestinal stromal tumors, who were treated with imatinib between May 2001 and December 2003, were included in this study. The clinical findings and CT scans were retrospectively reviewed. The metastatic lesions were assessed according to the location, size (greatest diameter), attenuation, and the enhancing pattern before and after imatinib treatment. Prior to the treatment, the sizes and attenuation values of the metastatic lesions ranged from 5 to 20 cm and from 63 to 131 H, respectively. The metastatic lesions showed a heterogeneous enhancement pattern on the contrast-enhanced CT scans. After the treatment, the metastatic lesions became smaller in all 11 patients, and the corresponding attenuation value ranged from 15 to 51 H. The metastatic lesions became homogeneous and cystic in appearance on the follow-up CT scans, mimicking ascites. Intra-abdominal extra-hepatic metastases of patients with gastrointestinal stromal tumors treated with imatinib may appear as well-circumscribed cystic lesions on contrast-enhanced CT. These metastases are likely to become smaller and resemble ascites, but may persist indefinitely on the follow-up CT.

    Full Text Available Postoperative intra-abdominal adhesion is a very common complication after abdominal surgery. One clinical problem that remains to be solved is to identify an ideal strategy to prevent abdominal adhesions. Keratinocyte growth factor (KGF has been proven to improve the proliferation of mesothelial cells, which may enhance fibrinolytic activity to suppress postoperative adhesions. This study investigated whether the combined administration of KGF and a sodium hyaluronate (HA gel can prevent intra-abdominal adhesions by improving the orderly repair of the peritoneal mesothelial cells. The possible prevention mechanism was also explored. The cecum wall and its opposite parietal peritoneum were abraded after laparotomy to induce intra-abdominal adhesion formation. Animals were randomly allocated to receive topical application of HA, KGF, KGF + HA, or normal saline (Control. On postoperative day 7, the adhesion score was assessed with a visual scoring system. Masson’s trichrome staining, picrosirius red staining and hydroxyproline assays were used to assess the magnitude of adhesion and tissue fibrosis. Cytokeratin, a marker of the mesothelial cells, was detected by immunohistochemistry. The levels of tissue plasminogen activator (tPA, interleukin-6 (IL-6, and transforming growth factor β1 (TGF-β1 in the abdominal fluid were determined using enzyme-linked immunosorbent assays (ELISAs. Western blotting was performed to examine the expression of the TGF-β1, fibrinogen and α-smooth muscle actin (α-SMA proteins in the rat peritoneal adhesion tissue. The combined administration of KGF and HA significantly reduced intra-abdominal adhesion formation and fibrin deposition and improved the orderly repair of the peritoneal mesothelial cells in the rat model. Furthermore, the combined administration of KGF and HA significantly increased the tPA levels but reduced the levels of IL-6, tumor necrosis factor α (TNF-α and TGF-β1 in the abdominal fluid. The

However, the role of fat as a predictor of HBP in adolescents remains unknown. OBJECTIVE: To investigate the association between general and abdominal obesity with HBP and to identify the sensitivity and specificity of these indicators to detect HBP in adolescents. METHODS: The sample was composed of 1,021 adolescents aged 10-17 years. Subjects were classified as normal, overweight/obese, according to BMI measurements, and as non-obese and with abdominal obesity, according to waist circumference (WC measurements. Systolic (SBP and diastolic (DBP blood pressure were assessed using an oscillometric device. Logistic regression and ROC curves were used in the statistical analysis. RESULTS: The overall prevalence of HBP was 11.8% (13.4% in boys and 10.2% in girls. The prevalence of HBP among general overweight/obese boys and girls was 10% and 11.1%, respectively. The prevalence of HBP among boys with abdominal obesity was 28.6%. For both genders, the odds ratio (OR for HBP was higher in abdominal obesity than in general overweight/obesity (4.09 [OR95%CI = 2.57-6.51] versus 1.83 [OR95%CI = 1.83-4.30]. The OR for HBP was higher when general overweight/obesity and abdominal obesity were clustered (OR = 4.35 [OR95%CI = 2.68-7.05], than when identified by either general overweight/obesity or abdominal obesity alone (OR = 1.32 [OR95%CI = 0.65-2.68]. However, both types of obesity had low predictive power in HBP detection. CONCLUSION: General and abdominal obesity were associated to HBP, however, the sensitivity and specificity of these variables to detect HBP are low in Brazilian adolescents.

    Up to 93% of patients undergoing abdominal surgery will develop intra-abdominal adhesions with the subsequent morbidity that they represent. Various substances have been tested for the prevention of adhesions with controversial results; the aim of our study is to compare the capability of pirfenidone in adhesion prevention against sodium hyaluronate/carboxymethylcellulose. A randomized, prospective, longitudinal experimental study with Winstar rats. They were divided into 3 groups. The subjects underwent an exploratory laparotomy and they had a 4cm(2) cecal abrasion. The first group received saline on the cecal abrasion, and groups 2 and 3 received pirfenidone and sodium hyaluronate/carboxymethylcellulose respectively. All rats were sacrificed on the 21st day after surgery and the presence of adhesions was evaluated with the modified Granat scale. Simple frequency, central tendency and dispersion measures were recorded. For the statistical analysis we used Fisher's test. To evaluate adhesions we used the Granat's modified scale. The control group had a median adhesion formation of 3 (range 0-4). The pirfenidone group had 1.5 (range 0-3), and the sodium hyaluronate/carboxymethylcellulose group had 0 (range 0-1). There was a statistically significant difference to favor sodium hyaluronate/carboxymethylcellulose against saline and pirfenidone (P<0.009 and P<.022 respectively). The use of sodium hyaluronate/carboxymethylcellulose is effective for the prevention of intra-abdominal adhesions. More experimental studies are needed in search for the optimal adhesion prevention drug. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available OBJETIVO: Avaliar a associação entre marcadores antropométricos de adiposidade corporal (índice de massa corporal e circunferência da cintura e hipertensão arterial. MÉTODOS: Estudo de corte transversal, de base populacional, realizado no período de 2003 a 2004, com 1.298 indivíduos de 20 a 59 anos. Foram considerados hipertensos os indivíduos com pressão arterial > 140/90 mmHg ou em uso de medicação anti-hipertensiva. As associações entre os indicadores antropométricos e a hipertensão arterial foram analisadas por regressão de Poisson, ajustada por potenciais fatores de confusão (sexo, idade, escolaridade, tabagismo, consumo de bebida alcoólica e atividade física no lazer. A curva ROC foi utilizada para determinar o melhor ponto de corte do IMC para detecção da hipertensão arterial. RESULTADOS: A prevalência de hipertensão arterial foi de 28,3%, sendo 33,5% no sexo masculino e 23,5% no feminino. Após ajuste para o IMC e potenciais fatores de confusão, a circunferência da cintura perdeu associação com o desfecho avaliado, permanecendo apenas o IMC com poder de explicação para a hipertensão arterial (RP = 1,05, p = 0,001. O melhor ponto de corte para o IMC no sexo masculino foi de 25,6 Kg/m², e no sexo feminino 25,7 Kg/m². CONCLUSÕES: A associação observada entre a circunferência da cintura e a hipertensão arterial em muitos estudos pode estar relacionada à ausência de controle de potenciais fatores de confusão nas análises, bem como à não remoção do efeito da adiposidade total. Novas investigações devem ser conduzidas na população brasileira, a fim de se verificar as verdadeiras associações entre indicadores antropométricos e vários desfechos, estudando-se também os melhores pontos de corte desses indicadores.OBJECTIVE: To assess the association between the anthropometric indexes of body adiposity (body mass index - BMI and waist circumference and hypertension.

    We derive and validate clinical prediction rules to identify adult patients at very low risk for intra-abdominal injuries after blunt torso trauma. We prospectively enrolled adult patients (>or=18 years old) after blunt torso trauma for whom diagnostic testing for intra-abdominal injury was performed. In the derivation phase, we used binary recursive partitioning to create a rule to identify patients with intra-abdominal injury who were undergoing acute intervention (including therapeutic laparotomy or angiographic embolization) and a separate rule for identifying patients with any intra-abdominal injury present. We considered only clinical variables readily available with acceptable interrater reliability. The prediction rules were then prospectively validated in a separate cohort of patients. In the derivation phase, we enrolled 3,435 patients, including 311 (9.1%; 95% confidence interval [CI] 8.1% to 10.1%) with intra-abdominal injury and 109 (35.0%; 95% CI 29.7% to 40.6%) with intra-abdominal injury requiring acute intervention. In the validation study, we enrolled 1,595 patients, including 143 (9.0%; 95% CI 7.6% to 10.5%) with intra-abdominal injury. The derived rule for patients with intra-abdominal injuries who were undergoing acute intervention consisted of hypotension, Glasgow Coma Scale (GCS) score less than 14, costal margin tenderness, abdominal tenderness, hematuria level greater than or equal to 25 red blood cells/high powered field, and hematocrit level less than 30% and identified all 44 patients in the validation phase with intra-abdominal injury who were undergoing acute intervention (sensitivity 44/44, 100%; 95% CI 93.4% to 100%). The derived rule for the presence of any intra-abdominal injury consisted of GCS score less than 14, costal margin tenderness, abdominal tenderness, femur fracture, hematuria level greater than or equal to 25 red blood cells/high powered field, hematocrit level less than 30%, and abnormal chest radiograph result

    to evaluate the association between serum levels of procalcitonin and C-reactive protein, on the first 3 postoperative days, and the appearance of postoperative intra-abdominal infection. Prospective observational study including 67 patients operated on for colo-rectal, gastric and pancreatic cancer. Serum levels of procalcitonin and C-reactive protein were analyzed before surgery and daily until the third postoperative day. Values of procalcitonin (PCT) and C-reactive protein (CRP) were recorded as well as their accuracy for detection of postoperative intra-abdominal infection (PIAI). The incidence of postoperative intra-abdominal infection was 13.4%. CRP serum levels at 72h, PCT serum levels at 24, 48 and 72h and the ratio between serum levels of CRP at 72hours and serum levels of CRP at 48hours (CRP D3/CRP D2) were significantly associated with the appearance of postoperative intra-abdominal infection. The highest sensitivity corresponded to PCT at 72hours (88.9%); the highest specificity and positive predictive value corresponded to the ratio CRP D3/CRP D2 (96.49% and 71.4%, respectively); the highest negative predictive value to procalcitonin at 72h and 24h. Serum levels of PCT are significantly associated with the appearance of postoperative intra-abdominal infection. Sensitivity and predictive positive values are low, but negative predictive value is high, even at 24h after surgery. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    Patients with recent intraabdominal events are at uniquely risk for intraabdominal candidiasis (IAC). Candida peritonitis is a frequent and life-threatening complication in surgically ill patients. International guidelines do not specifically address IAC. This study describes clinical features of IAC in critical patients treated with anidulafungin in Surgical ICUs (SICUs). A practice-based retrospective study was performed including all adults with IAC admitted to 19 SICUs for ≥24h treated with anidulafungin. IAC was documented (Candida isolation from blood/peritoneal fluid/abscess fluid and/or histopathological confirmation) or presumptive (host factors plus clinical criteria without mycological support). Total population and the subgroup of septic shock patients were analyzed. One hundred and thirty nine patients were included, 94 (67.6%) with septic shock, 112 (86.2%) after urgent surgery. Of them, 77.7% presented peritonitis and 21.6% only intraabdominal abscesses. Among 56.8% cases with documented IAC, C. albicans (52.8%) followed by C. glabrata (27.8%) were the most frequent species. Anidulafungin was primarily used as empirical therapy (59.7%), microbiologically directed (20.9%) and anticipated therapy (15.8%). Favourable response was 79.1% (76.6% among patients with septic shock). Intra-SICU mortality was 25.9% (28.7% among patients with septic shock). Among IACs managed at SICUs, peritonitis was the main presentation, with high percentage of patients presenting septic shock. C. albicans followed by C. glabrata were the main responsible species. Anidulafungin treatment was mostly empirical followed by microbiologically directed therapy, with a favourable safety profile, even among patients with septic shock.

    2016-05-01

    Full Text Available BACKGROUND AND AIMS Increased intra-abdominal pressure (IAP, also referred to as intra-abdominal hypertension (IAH, affects organ function in critically ill patients. The prevalence of IAH is between 32% - 65% in intensive care units. Normal IAP is ≈ 5–7 mmHg. According to WSACS definition, IAH = IAP ≥12 mmHg and is divided into 4 grades. They are Grade I (12-15 mmHg, Grade II (16-20 mmHg, Grade III (21-25 mmHg, Grade IV (>25 mmHg. Transvesical measurement of IAP currently is the most popular technique. Several systems with or without the need for electronic equipment are available that allow IAP measurement. The aim is to study the incidence of IAH in critically ill patients, to assess the risk factors for development of IAH, to study the role of IAH as a risk factor for Acute Kidney Injury (AKI, to assess the role of IAH as a risk factor for increased (Intensive Care Unit ICU mortality. SUBJECTS AND METHODS This is a prospective observational study. Study period was six months. The study included 52 patients admitted to Medical ICU in Government Medical College, Kozhikode, Kerala. RESULTS AND CONCLUSION There was a very high incidence of intra-abdominal hypertension in critically ill patients. IAH was significantly associated with risk factors like sepsis, mechanical ventilation, pancreatitis, capillary leak, ascites, cumulative fluid balance and cirrhosis. IAH is an independent risk factor for development of acute kidney injury. IAH is an independent predictor of mortality in critically ill patients.

    Full Text Available Antimicrobial stewardship programs (ASPs focus on improving the utilization of broad spectrum antibiotics to decrease the incidence of multidrug-resistant Gram positive and Gram negative pathogens. Hospital admission for both medical and surgical intra-abdominal infections (IAIs commonly results in the empiric use of broad spectrum antibiotics such as fluoroquinolones, beta-lactam beta-lactamase inhibitors, and carbapenems that can select for resistant organisms. This review will discuss the management of uncomplicated and complicated IAIs as well as highlight stewardship initiatives focusing on the proper use of broad spectrum antibiotics.

    The insertion of sewing needles into the abdominal cavity is an uncommon form of child abuse. We report a 2-and-a-half-year-old boy with 2 intra-abdominal sewing needles that were discovered during the evaluation of chronic abdominal pain and vomiting. This case report illustrates the wide range with which abusive injury can present in children. Pediatricians need to be alerted to this newly-recognized and the increasing form of child abuse so that they examine and diagnose their patients appropriately.

    Serious intra-abdominal injuries are very uncommon in cricket; traumatic cricket injuries are traditionally musculoskeletal, soft tissue or maxillofacial in origin. The cause of such cricket injuries can be broadly divided into collision type injuries (a result of direct contact with the ball or bat, another player, the ground or boundary) or overuse injuries (due to running, throwing, batting, bowling, repetitive movements and overexertion). This case report describes a rare cause of small bowel perforation and suspected genitofemoral nerve injury secondary to the direct impact of a cricket ball, and includes a brief review of blunt abdominal injuries resulting in isolated small bowel perforations. 2015 BMJ Publishing Group Ltd.

    The literature on perioperative acute kidney injury (AKI) focuses mainly on cardiac and major vascular surgery. Among noncardiac general surgery procedures, intraabdominal general surgery has been identified as high risk for developing AKI, but variations in AKI risk and its impact on 30-day mortality among different types of abdominal surgeries are not well characterized. We used the American College of Surgeons National Surgical Quality Improvement Program (2005-2010) to identify patients in 15 intraabdominal general surgery procedure categories (n = 457,656). AKI was defined as an increase in the creatinine level of >2 mg/dL above baseline and/or dialysis. Relative risk regression modeling was used to assess the relative risks of AKI across the procedures. The relationships among surgical procedure, AKI, and 30-day mortality stratified by procedure type were assessed using relative risk regression. The overall incidence of AKI among intraabdominal surgery patients was 1.1%, which varied from 0.2% in appendectomy and 0.3% in gastric bypass patients to 2.6% in small bowel resection and 3.5% in exploratory laparotomy patients. Of the patients who developed AKI, 31.3% died within 30 days, compared with 1.9% of those who did not develop AKI. After adjusting for comorbidities and operative factors, AKI was associated with a 3.5-fold increase in the risk of 30-day mortality (adjusted risk ratio, 3.51, 95% confidence interval [CI], 3.29-3.74). Among individual procedures, the estimated adjusted risk ratio of 30-day mortality associated with AKI ranged from 1.87 (95% CI, 1.62-2.17) in exploratory laparotomy to 31.6 (95% CI, 17.9-55.9) in gastric bypass. The incidence of AKI and the impact of AKI on 30-day mortality vary markedly across procedures within intraabdominal general surgery. This highlights the importance of preoperative risk stratification and identifies procedure type as a significant risk factor for AKI and 30-day mortality.

    Full Text Available Despite their frequent appearance, intra-abdominal adhesions are rarely the subject of clinical studies and academic discussions. For many years the operators have been trying to reduce such unfavourable consequences of interventions in the abdominal structures. The aim of this article is to present the possibilities of intra-abdominal adhesion diagnostics by means of ultrasound imaging based on authors’ own experience and information included in pertinent literature. The anatomy and examination technique of the abdominal wall were discussed in Part I of the article. In order to evaluate intraperitoneal adhesions, one should use a convex transducer with the frequency of 3.5–6 MHz. The article provides numerous examples of US images presenting intra-abdominal adhesions, particularly those which appeared after surgical procedures. The significance of determining their localisation and extensiveness prior to a planned surgical treatment is emphasized. Four types of morphological changes in the ultrasound caused by intra-abdominal adhesions are distinguished and described: visceroperitoneal adhesions, intraperitoneal adhesions, adhesive obstructions as well as adhesions between the liver and abdominal wall with a special form of such changes, i.e. hepatic pseudotumour. Its ultrasound features are as follows: 1. The lesion is localised below the scar in the abdominal wall after their incision. 2. The lesion is localised in the abdominal part of the liver segments III, IV and V. 3. With the US beam focus precisely set, the lack of fascia – peritoneum complex may be noticed. An uneven liver outline or its ventral displacement appears. 4. A hepatic adhesion-related pseudotumour usually has indistinct margins, especially the posterior one, and, gradually, from top to bottom, loses its hypoechogenic nature. 5. In a respiration test, this liver fragment does not present the sliding movement – a neoplastic tumour rarely shows such an effect

    2016-08-01

    We present a female neonate born with prune belly syndrome (PBS) in whom a large intraabdominal cyst was diagnosed at 12weeks of gestation. Rapid and exponential growth of the cyst caused pressure effects on the intraabdominal organs and stretching of the anterior abdominal wall by 19weeks of gestation. This led to drainage of the massive cyst at 20weeks of gestation to prevent fetal demise. This case provides further clues to the likely etiology of PBS: transient stretching and attenuation of the fetal abdominal wall secondary to gross fetal abdominal distension - from any cause.

    Full Text Available Background. We aimed to describe the incidence of intra-abdominal hypertension (IAH and gastrointestinal (GI symptoms and related outcome in mechanically ventilated (MV patients. Methods. Intra-abdominal pressure (IAP and gastric residual volumes were measured at least twice daily. IAH was defined as a mean daily value of IAP≥12 mmHg. Results. 398 patients were monitored for all together 2987 days. GI symptom(s occurred in 80.2% patients. 152 (38.2% patients developed IAH. Majority (93.4% of patients with IAH had GI symptoms. The more severe IAH was associated with the higher number of concomitant GI symptoms (P<.001. 142 (35.7% patients developed both IAH and at least one GI symptom at any time in ICU, and in 77 patients they occurred simultaneously on the same day. This subgroup had the highest ICU mortality (21.8%. In contrast, the small group of patients presenting only IAH, but not GI symptoms (10 patients, had no lethal outcome. Three patients (4.4% died without showing either IAH or GI symptoms. Conclusions. GI symptoms and IAH often, but not always, occur together. The patients having IAH solely without developing GI symptoms have rather good outcome.

    AIM: This study aims to evaluate the algorithm of procalcitonin (PCT) and its role on the duration of antibiotics prescription for intra-abdominal infections. MATERIALS AND METHODS: This study is a prospective controlled study that is conducted in groups of 50 hospitalised patients and 50 controlled group patients. RESULTS: The results indicated that the average duration of antibiotic delivery to the PCT group was -10.6 days (SD ± 6.6 days), while in the control group -13.2 days (SD ± 4.2 days). These data showed a significant difference in the duration of antibiotic therapy and the monitoring role of PCTs in the prediction success of antibiotic treatment. The antibiotic delivery was longer in the septic shock 17 (SD ± 11.7) that corresponds to high PCT values of 67.8 (SD ± 50.9). Recurrence of the infection after the cessation of antibiotics occurred in 2 cases (4%) in the standard group, while it occurred in 3 cases (6%) in the control group. CONCLUSION: The treatment of the intra-abdominal infections based on the PCT algorithm shortens the duration of antibiotic treatment and does not pose a risk for the recurrence of the infection.

    Full Text Available Background : Studies have documented the impact of intra-abdominal hypertension (IAH on virtually every organ. However, it still remains strangely underdiagnosed. The aims of the study were to assess, in patients undergoing emergency laparotomy, whether intra-abdominal pressure (IAP is an independent predictor of morbidity and mortality, to evaluate the effects of IAH, and to identify hidden cases of abdominal compartment syndrome (ACS. Materials and Methods : The study comprised 197 patients undergoing emergency laparotomy. IAP was measured preoperatively and then postoperatively at 0, 6, and 24 hours. Duration of hospital stay, occurrence of burst abdomen, and mortality were noted as outcomes. Results : At admission, incidence of IAH was 80%. No significant association was found between IAP and occurrence of burst abdomen (P > 0.1. IAP was found to be a significant predictor of mortality in patients undergoing laparotomy (P < 0.001. Elevated IAP was found to affect all the organ systems adversely. The incidence of post-op ACS was 3.05% in the general population and 13.16% in trauma patients. The mortality rate for this subgroup was 100%. Conclusions : IAP is a significant predictor of mortality in patients undergoing laparotomy. IAH has detrimental effects on various organ systems. A more frequent monitoring with prompt decompression may be helpful in decreasing the mortality rate. Further studies are required to establish a screening protocol in patients undergoing laparotomy to detect and manage cases of IAH and ACS.

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

    In our present study, we aimed to evaluate the effects of taurolidine, a blocking agent of fibrin deposition, and icodextrin, a colloid osmotic material that also inhibits fibrin accumulation, and the effect of their application separately and concomittantly in intra-abdominal adhesion prevention. Forty BALB/c male mice, weighing 30-35 g and 11-12 weeks old were divided into four groups as follows: group 1: control group, group 2: taurolidine group, group 3: icodextrin group, and group 4: taurolidine and icodextrin group. Animals were sacrificed by cervical dislocation after 14 days. The adhesions were classified and scored by two blinded researchers according to Nair's macroscopic adhesion staging system and microscopically evaluated using Zuhlke classification system. In group 2 there was no mice with score 4. In group 3, scores 3 and 4 were absent. Scores 2, 3, and 4 were not detected in group 4. The mean value of adhesion scores decreased from groups 1 to 4. There was a significant statistical difference between all the groups and group 1. There was no change between the study groups on macroscopic examination, whereas histopathological examination revealed statistically significance between group 4 and other groups. Taurolidine and icodextrin, when used alone or together, decrease postoperative intra-abdominal adhesion formation. Macroscopic appearence was not supportive of statistical difference between group 4 and other groups. Microscopic evaluation paves the road for future studies for determining significance when taurolidine and icodextrin are applied concomittantly. Additional experimental studies are required for dose adjustment.

    Full Text Available Intra-abdominal hypertension (IAH can damage multiple organ systems, but the explicit impact on the adrenal gland is unclear. To evaluate the effects of intra-abdominal pressure (IAP on the secretory function of the adrenal glands, we established canine models of IAH. By comparing morphology; hemodynamics; plasma cortisol, aldosterone, epinephrine, and norepinephrine concentrations; and the expression of IL-1, IL-6, and TNF-α in adrenal gland tissue from these dogs, we found that hemodynamic instability occurred after IAH and that IAH increased the plasma cortisol, aldosterone, epinephrine, and norepinephrine concentrations. Higher IAPs resulted in more significant changes, and the above indicators gradually returned to normal 2 h after decompression. Compared with the sham-operated group, IAH significantly increased IL-1, IL-6, and TNF-α levels in adrenal tissue, with larger increases in the presence of higher IAPs. However, the concentrations of these markers remained higher than those in the sham-operated group despite their decrease after 2 h of decompression. Histopathological examination revealed congestion, red blood cell exudation, and neutrophil infiltration in the adrenal glands when IAP was elevated; these conditions became more significant with more severe IAH. These results suggest that the secretion of adrenal hormones and adrenal gland inflammation are positively correlated with IAP and that abdominal decompression effectively corrects adrenal gland function.

    Intra-abdominal infections are associated with significant morbidity and mortality. The most frequent pathogens involved are the gastrointestinal flora which can cause poly-microbial infections. Microbiological diagnosis is required to determine the aetiology and antimicrobial susceptibility of the organisms involved. Prompt initiation of antimicrobials is essential for improving patient's outcome. Knowledge of local trends of antimicrobial resistance in nosocomial isolates is essential for empiric therapy. Methods: A total of 190 clinical isolates collected from intra-abdominal infections during July 2013 to July 2014 were included in the study. Organism identification and Antimicrobial sensitivity testing using standard biochemical tests and CLSI recommended criteria was carried out. Result: Of the total 190 isolates from abdominal infection sources 52% were from fluid sources (peritoneal and ascitic fluid), 41% were from gall bladder and 6.5% were from other abdominal sources. E. coli (46.8%) was the most frequently isolated gram negative and Enterococcus (13.1%) was the most frequently isolated gram positive organism. Carbapenem (imipenem) was the most active agent against enterobacteraceae exhibiting, 94.4% and 91.3% sensitivity against E. coli and Klebsiella respectively. While vancomycin was the most active agent against gram positive organisms. Eighty-four percent of the Enterococci isolated were sensitive to vancomycin. Most isolates exhibited resistance to one or more antibiotics. Conclusion: Continuous evolution of antimicrobial resistance patterns in bacteria necessitates updating of local data on antimicrobial susceptibility profiles to ensure the safety and efficacy of pathogen specific antimicrobial therapies.

    Full Text Available ABSTRACT: Intraoperative ultrasonography (IOUS is used in medicine for diagnosis and guidance during oncologic surgery. The aims of this study were to assess the performance, feasibility, advantages and difficulties of the IOUS technique in dogs with suspected intra-abdominal tumors. The study included nine client-owed dogs that had suspected intra-abdominal tumors (spleen, liver or bowel based on transabdominal ultrasound examination and that were subsequently referred for exploratory laparotomy surgery. During surgery, IOUS was performed; results of preoperative transabdominal ultrasonography, inspection by the surgeon and IOUS were compared on a case-by-case basis. IOUS was helpful in determining lesion resection in all cases. Lesions detected solely by the use of IOUS were observed in seven out of nine cases. Analysis of these cases demonstrated that IOUS can be a tool to assist during oncology surgery on the liver, spleen or bowel. Dogs with hepatic tumors can have small non-palpable intraparenchymal nodules, which may be visible by IOUS.

    Heterotopic ossification, an entity common in orthopaedic practice frequently involving the hip, knee or other joints, is rarely encountered in abdominal wounds and mesentery. This unusual condition, referred to as mesenteric ossification, is typically associated with intra-abdominal catastrophes. Surgical repair following such catastrophes has always been a challenge as the abdominal wall architecture is frequently distorted by the multiple laparotomies previously performed. In addition, the presence of several enterocutaneous fistulae further compounds the reconstruction approach, especially when mesh material is planned for use. We report a case of intra-abdominal heterotopic ossification with mesenteric involvement after a penetrating injury to the abdomen, followed by multiple laparotomies that ended in a complex abdominal wall hernia with major loss of domain, and multiple enterocutaneous fistulae. The patient was treated with resection of the bony deposits from the abdominal wound and cavity, along with excision of the fistula sites. This was followed by a component separation technique and the use of a biologic mesh graft to reconstruct the abdominal wall.

The drug is started at a low dose and gradually increased to a target dose of 300–450 mg/day. It is well known to cause agranulocytosis and neutropenia. Several cases of fatal sepsis have been reported in neutropenic patients and emphasis is placed on monitoring for agranulocytosis; however, clozapine also causes intestinal hypomotility and constipation, which if unrecognized can lead to intestinal obstruction, bowel necrosis, and intra-abdominal sepsis. Reduced behavioral pain reactivity in schizophrenics may alter the ability to express pain, potentially leading to a delay in the presentation for medical attention. We report a case of fatal intra-abdominal sepsis secondary to an unrecognized case of clozapine-related constipation.

    Standing laparoscopic procedures, facilitated by abdominal insufflation with carbon dioxide, are being employed to an increasingly greater extent in horses. However, a sustained increase in abdominal pressure may be life-threatening. A practical method for intra-abdominal pressure (IAP) assessment is imperative. Although indirect methods for estimating IAP have been extensively studied in man, little work has been performed in veterinary medicine. To investigate the utility of gastric manometry for purposes of evaluating IAP in horses. Gastric pressure (P(ga) ) was estimated by balloon manometry in 8 healthy, mature horses, before and during a 30 min passive pneumoperitoneum induced by right paralumbar puncture. The balloon manometer was positioned within the gastric lumen and inflated using 2 separate volumes of air: 10 and 50 ml. P(ga) Gastric pressure was determined at baseline (0) and 5, 15 and 30 min after induction of passive pneumoperitoneum. Intra-abdominal pressure was measured directly by right paralumbar puncture using an 8 gauge needle at baseline and immediately following establishment of passive pneumoperitoneum. Baseline IAP values were negative and increased (P≤0.05) during development of passive pneumoperitoneum. However, recorded P(ga) measurements for both inflation volumes were positive before (baseline) and during the course of the passive pneumoperitoneum. Measured P(ga) values did not correlate with IAP at any time. Our results suggest that the indirect method used in human patients for estimating IAP by P(ga) is not applicable for horses. © 2011 EVJ Ltd.

    The pathogenesis of intra-abdominal candidiasis is poorly understood. Mice were intraperitoneally infected with Candida albicans (1 × 10(6) colony-forming units) and sterile stool. nanoString assays were used to quantitate messenger RNA for 145 C. albicans genes within the peritoneal cavity at 48 hours. Within 6 hours after infection, mice developed peritonitis, characterized by high yeast burdens, neutrophil influx, and a pH of 7.9 within peritoneal fluid. Organ invasion by hyphae and early abscess formation were evident 6 and 24 hours after infection, respectively; abscesses resolved by day 14. nanoString assays revealed adhesion and responses to alkaline pH, osmolarity, and stress as biologic processes activated in the peritoneal cavity. Disruption of the highly-expressed gene RIM101, which encodes an alkaline-regulated transcription factor, did not impact cellular morphology but reduced both C. albicans burden during early peritonitis and C. albicans persistence within abscesses. RIM101 influenced expression of 49 genes during intra-abdominal candidiasis, including previously unidentified Rim101 targets. Overexpression of the RIM101-dependent gene SAP5, which encodes a secreted protease, restored the ability of a rim101 mutant to persist within abscesses. A mouse model of intra-abdominal candidiasis is valuable for studying pathogenesis and C. albicans gene expression. RIM101 contributes to persistence within intra-abdominal abscesses, at least in part through activation of SAP5.

    Infection of pancreatic necrosis, although present in less than 10% of acute pancreatitis, carries a high risk of mortality; debridment and drainage of necrosis is the treatment of choice, followed by 'open' or 'close' abdomen management. We recently introduced the use of intra-abdominal vacuum sealing after a classic necrosectomy and laparostomy. Two patients admitted to ICU for respiratory insufficiency and a diagnosis of severe acute pancreatitis developed pancreatic necrosis and were treated by necrosectomy, lesser sac marsupialisation and posterior lumbotomic opening. Both of the patients recovered from pancreatitis and a good healing of laparostomic wounds was obtained with the use of the VAC system. Most relevant advantages of this technique seem to be: the prevention of abdominal compartment syndrome, the simplified nursing of patients and the reduction of time to definitive abdominal closure. © 2010 The Authors.

  5. Effects of anabolic steroids on acute phase responses in intra-abdominal sepsis

    Directory of Open Access Journals (Sweden)

    K. Mealy

    1997-01-01

    Full Text Available The acute phase response is an important adaptive response to sepsis and injury. As anabolic steroids increase protein synthesis we postulated that these agents might also increase hepatic acute phase protein synthesis. Male Wistar rats were pretreated with testosterone or danazol for 48 h prior to caecal ligation and puncture (CLP. Thirty-six h following surgery the animals were killed and blood taken for full blood count, total protein, albumin, α, β and γ globulin fractions on serum electrophoresis, complement C3 and transferrin levels. Danazol increased the α1, α2 and β1 globulin serum protein fractions in comparison with no surgery and CLP alone groups. These results indicate that danazol increases plasma acute phase proteins, as measured by electrophoresis, in this model of intra-abdominal sepsis.

    Full Text Available Bilateral cryptorchidism is a rare occurrence and seminoma is the most common germ cell tumor found in undescended testes when they occur. We present the case of a patient with bilateral cryptorchidism who presented to our trauma center after a motor vehicle collision and was found incidentally to have a 17-cm intra-abdominal mass. The mass was subsequently biopsied and proven to be seminoma. The patient completed three cycles of bleomycin/etoposide/cisplatin chemotherapy and successfully underwent a postchemo retroperitoneal lymph node dissection with no viable residual tumor or positive lymph nodes found in the surgical specimen. He also had an orchiopexy of the contralateral testicle. The patient recovered fully and has been found to be recurrence-free four months postoperatively. We highlight the importance of cisplatin-based chemotherapy and extensive tumor resection as the mainstay of initial cancer control.

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

  9. Therapeutic Role of Interleukin 22 in Experimental Intra-abdominal Klebsiella pneumoniae Infection in Mice.

    Interleukin 22 (IL-22) is an IL-10-related cytokine produced by T helper 17 (Th17) cells and other immune cells that signals via IL-22 receptor alpha 1 (IL-22Ra1), which is expressed on epithelial tissues, as well as hepatocytes. IL-22 has been shown to have hepatoprotective effects that are mediated by signal transducer and activator of transcription 3 (STAT3) signaling. However, it is unclear whether IL-22 can directly regulate antimicrobial programs in the liver. To test this hypothesis, hepatocyte-specific IL-22Ra1 knockout (Il22Ra1(Hep-/-)) and Stat3 knockout (Stat3(Hep-/-)) mice were generated and subjected to intra-abdominal infection with Klebsiella pneumoniae, which results in liver injury and necrosis. We found that overexpression of IL-22 or therapeutic administration of recombinant IL-22 (rIL-22), given 2 h postinfection, significantly reduced the bacterial burden in both the liver and spleen. The antimicrobial activity of rIL-22 required hepatic Il22Ra1 and Stat3. Serum from rIL-22-treated mice showed potent bacteriostatic activity against K. pneumoniae, which was dependent on lipocalin 2 (LCN2). However, in vivo, rIL-22-induced antimicrobial activity was only partially reduced in LCN2-deficient mice. We found that rIL-22 also induced serum amyloid A2 (SAA2) and that SAA2 had anti-K. pneumoniae bactericidal activity in vitro. These results demonstrate that IL-22, through IL-22Ra1 and STAT3 singling, can induce intrinsic antimicrobial activity in the liver, which is due in part to LCN2 and SAA2. Therefore, IL-22 may be a useful adjunct in treating hepatic and intra-abdominal infections. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

    No conclusive results on the efficacy and timing of open abdomen (OA) are available, particularly in the setting of intra-abdominal infections. We analyzed outcomes and risk factors retrospectively in a large series of patients managed with an OA during the past 20 y in an effort to clarify this issue. We reviewed the records of 133 patients who underwent treatment with an OA, considering factors related to patient, disease, medical management, and surgical treatment. The end points of the bi-variable analysis were 1-y mortality, calculated from the time of an initial OA procedure, and definitive fascial closure. Most patients (112/133) managed with an OA had one of several types of peritonitis. Many patients had severe clinical conditions (mean Acute Physiology and Chronic Health Evaluation [APACHE] II score was almost 9 points for the study population). With regard to surgical management, the mean (+SD) number of abdominal revisions was 5.9+9.3 during a mean duration of treatment with an OA of 14.3+11.6 d. The overall mortality in the study was 26% (35/133). Bi-variable analysis revealed factors associated with overall mortality to be age, renal and respiratory co-morbidities, edema on an initial chest radiograph, blood pressure, blood glucose and creatinine concentrations; and APACHE II score. The rate of definitive fascial closure was 75% (100/133). Factors associated negatively with fascial closure were respiratory co-morbidity, edema on a first chest radiograph, post-operative mesenteric ischemia as an indication for OA, blood glucose and creatinine concentrations, and duration of an OA. Patients' pre-operative clinical status influences strongly their response to surgical treatment. The management of OA does not affect adversely the survival of patients with intra-abdominal infections, but factors related to the management of OA (duration of OA) seem to affect the possibility of definitive fascial closure.

    Abdominal Compartment Syndrome (ACS) is an uncommon but deleterious complication after trauma laparotomy. Early recognition of patients at risk of developing ACS is crucial for their outcome. The aim of this study was to compare the characteristics of patients who developed high-grade intra-abdominal hypertension (IAH) (i.e., grade III or IV; intra-abdominal pressure, IAP >20 mm Hg) following an injury-related laparotomy versus those who did not (i.e., IAP ≤20 mm Hg). A retrospective analysis of consecutive trauma patients admitted to a level 1 trauma centre in Australia between January 1, 1995 and January 31, 2010 was performed. A comparison was made between characteristics of patients who developed high-grade IAH following trauma laparotomy versus those who did not. A total of 567 patients (median age 31 years) were included in this study. Of these patients 10.2% (58/567) developed high-grade IAH of which 51.7% (30/58) developed ACS. Patients with high-grade IAH were older (pgrade IAH received larger volumes of crystalloids (pgrade IAH suffered higher mortality rates (25.9% (15/58) vs. 12.2% (62/509); p=0.012). Of all patients who underwent a trauma laparotomy, 10.2% developed high-grade IAH, which increases the risk of mortality. Patients with acidosis, coagulopathy, and hypothermia were especially at risk. In these patients, the abdomen should be left open until adequate resuscitation has been achieved, allowing for definitive surgery. This is a level III retrospective study.

    Little information is available on the distribution of antimicrobial resistance genes in anaerobes in Japan. To understand the background of antimicrobial resistance in anaerobes involved in intra-abdominal infections, we investigated the distribution of eight antimicrobial resistance genes (cepA, cfiA, cfxA, ermF, ermB, mefA, tetQ, and nim) and a mutation in the gyrA gene in a total of 152 organisms (Bacteroides spp., Prevotella spp., Fusobacterium spp., Porphyromonas spp., Bilophila wadsworthia, Desulfovibrio desulfuricans, Veillonella spp., gram-positive cocci, and non-spore-forming gram-positive bacilli) isolated between 2003 and 2004 in Japan. The cepA gene was distributed primarily in Bacteroides fragilis. Gene cfxA was detected in about 9 % of the Bacteroides isolates and 75 % of the Prevotella spp. isolates and did not appear to contribute to cephamycin resistance. Two strains of B. fragilis contained the metallo-β-lactamase gene cfiA, but they did not produce the protein product. Gene tetQ was detected in about 81, 44, and 63 % of B. fragilis isolates, other Bacteroides spp., and Prevotella spp. isolates, respectively. The ermF gene was detected in 25, 13, 56, 64, and 16 % of Bacteroides spp., Prevotella spp., Fusobacterium spp., B. wadsworthia, and anaerobic cocci, respectively. Gene mefA was found in only 10 % of the B. fragilis strains and 3 % of the non-B. fragilis strains. Genes nim and ermB were not detected in any isolate. Substitution at position 82 (Ser to Phe) in gyrA was detected in B. fragilis isolates that were less susceptible or resistant to moxifloxacin. This study is the first report on the distribution of resistance genes in anaerobes isolated from intra-abdominal infections in Japan. We expect that the results might help in understanding the resistance mechanisms of specific anaerobes.

  13. Relationship between ventral hernia defect area and intra-abdominal pressure: dynamic in vivo measurement.

    It is an acceptable concept that the ventral hernia defect area will increase with a rise in intra-abdominal pressure (IAP). The literature lacks the evidence about how much this increase is in vivo. The aim of this study was to objectively measure the change in the ventral hernia defect area with increasing intra-abdominal pressure. In a prospective study of laparoscopic ventral hernia repair, the area of hernia defect was measured from inside the abdomen using a sterile paper ruler. The horizontal (width) and vertical (length) measurements of the defect were taken at two pressure points: (IAP = 8 mmHg) and (IAP = 15 mmHg). The hernia defect area was calculated as an oval shape using a standard formula. Eighteen consecutive patients with a ventral hernia were included in this study (8 males: 10 females). Median age was 60 years (30-81), body mass index (BMI) was 29.9 (22.6-37.6). Changing the IAP significantly, (P hernia defect. The median calculated defect area, as an oval shape, was 5.6 cm(2) (Q1-Q3 = 3.5-15.5) and 6.9 cm(2) (Q1-Q3 = 4.5-18.7) at 8 and 15 mmHg IAP, respectively. The calculated area of mesh required to cover the defect with a 5 cm overlap increased by a median of 5% (Q1-Q3 = 3-6%). The change in defect area did not differ significantly between obese and non-obese patients (P = 0.5). Dynamic, rather than static, measurements of ventral hernia area during laparoscopy provide a simple way of in vivo objective measurement that helps the surgeon choose the appropriate area of mesh. When choosing mesh area, we support the trend toward a larger overlap of at least 5 cm if less precise methods of measuring defect area are been used.

  14. Responses of intra-abdominal pressure and abdominal muscle activity during dynamic trunk loading in man.

    The purpose of this study was to determine and compare interactions between the abdominal musculature and intra-abdominal pressure (IAP) during controlled dynamic and static trunk muscle loading. Myoelectric activity was recorded in six subjects from the rectus abdominis, obliquus externus, obliquus internus, transversus abdominis and erector spinae muscles using surface and intra-muscular fine-wire electrodes. The IAP was recorded intra-gastrically. Trunk flexions and extensions were performed lying on one side on a swivel table. An adjustable brake provided different friction loading conditions, while adding weights to an unbraked swivel table afforded various levels of inertial loading. During trunk extensions at all friction loads, IAP was elevated (1.8-7.2 kPa) with concomitant activity in transversus abdominis and obliquus internus muscles--little or no activity was seen from rectus abdominis and obliquus externus muscles. For inertia loading during trunk extension, IAP levels were somewhat lower (1.8-5.6 kPa) and displayed a second peak when abdominal muscle activity occurred in the course of decelerating the movement. For single trunk flexions with friction loading, IAP was higher than that seen in extension conditions and increased with added resistance. For inertial loading during trunk flexion, IAP showed two peaks, the larger first peak matched peak forward acceleration and general abdominal muscle activation, while the second corresponded to peak deceleration and was accompanied by activity in transversus abdominis and erector spinae muscles. It was apparent that different loading strategies produced markedly different patterns of response in both trunk musculature and intra-abdominal pressure.

    In this study we aimed to investigate whether there is an effect of N2O on postoperative nausea and vomiting (PONV) via intraabdominal pressure (IAP). A total of 40 patients with risk class ASA I-II and age ranging between 20 and 50 years were enrolled in the study. The patients were monitored for electrocardiography (ECG), peripheral oxygen saturation (SpO2), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), end-tidal carbon dioxide (ETCO2) and body temperature. IAP was measured by a central venous pressure manometer placed in the urine catheter. Heart rate (HR), SpO2, SBP, DBP, MBP, ETCO2, body temperature and IAP were measured before the induction of anesthesia and every 10 minutes throughout the operation. Nausea and vomiting were questioned at the first and second postoperative hours. The patients were randomly grouped into two groups. Induction in both groups was provided using 2 mg/kg propofol, 2 µg/kg fentanyl and 0.1 mg/kg vecuronium, and endotracheal intubation was performed. The maintenance of anesthesia was provided by 40 % O2 + 60 % N2O, 1-2 % sevoflurane and 50 µg fentanyl + 2 mg vecuronium every 45 minutes in the first group. In the second group, 60 % dry air was used instead of 60 % N2O. There was no significant difference in terms of HR, SpO2, SBP, MBP, ETCO2, body temperature, nausea-vomiting and IAP. In conclusion, we think that N2O usage during the general anesthesia in patients without intraabdominal problems may increase IAP level for some degree whereas it does not increase PONV. In addition, N2O usage does not change ETCO2 values (Tab. 3, Fig. 3, Ref. 32).

    Although in the last decade the management of invasive fungal infections has improved, a number of controversies persist regarding the management of complicated intra-abdominal infection and surgical extended length-of-stay (LOS) patients in intensive care unit (ICU). To identify the essential clinical knowledge and elaborate a set of recommendations, with a high level of consensus, necessary for the management of postsurgical patients with complicated intra-abdominal infection and surgical patients with ICU extended stay. A Spanish prospective questionnaire, which measures consensus through the Delphi technique, was anonymously answered and e-mailed by 30 multidisciplinary national experts, all of them specialists in fungal invasive infections from six scientific national societies; these experts were intensivists, anesthesiologists, microbiologists, pharmacologists and specialists in infectious diseases. They answered 11 questions drafted by the coordination group after conducting a thorough review of the literature published in the last few years. For a category to be selected, the level of agreement among the experts in each should be equal to or greater than 70%. In a second round, 73 specialists attended a face-to-face meeting which was held after extracting recommendations from the chosen topics and in which they validated the pre-selected recommendations and derived algorithm. After the second Delphi round, the following 11 recommendations with high degree of consensus were validated. For "surgical patients" seven recommendations were validated: (1) risk factors for invasive candidiasis (IC), (2) usefulness of blood culture and direct examination of abdominal fluid to start empirical treatment; (3) PCR for treatment discontinuation; (4) start antifungal treatment in patients with anastomotic leaks; (5) usefulness of Candida score (CS) but not (6) the Dupont score for initiating antifungal therapy in the event of anastomotic leakage or tertiary peritonitis

OBJETIVO: Foi avaliada a via do óxido nítrico/L-arginina na resposta vascular de ratos obesos por dieta rica em gordura, enfocando as células endoteliais e do músculo liso. MÉTODOS: Ratos com 30 dias de vida foram divididos em 2 grupos: controle (C e obeso (OB, ratos sob dieta rica em gordura por 30 semanas. Após 30 semanas, foram registrados o peso corporal, índice de adiposidade, pressão arterial e perfis metabólicos e endócrinos dos animais. Foram obtidas curvas para noradrelanina na ausência e presença de inibidor de óxido nítrico sintase (L-NAME, 3x10-4M em aorta torácica intacta e com desnudamento em ratos C e OB. RESULTADOS: As medidas de peso corporal, índice de adiposidade, leptina e insulina aumentaram nos ratos OB, enquanto a pressão arterial permaneceu inalterada. A obesidade também produziu tolerância à glicose e resistência à insulina. A reatividade à noradrenalina da aorta intacta foi similar em ratos C e OB. A presença de L-NAME produziu um aumento similar nas respostas máximas, mas um desvio maior à esquerda das respostas nas aortas intactas dos ratos C em relação aos ratos OB [EC50 (x10-7M: C = 1,84 (0,83-4,07, O = 2,49 (1,41-4,38; presença de L-NAME C = 0,02 (0,01-0,04*, O = 0,21 (0,11-0,40*†,*p < 0,05 vs controle respectivo,†p < 0,05 vs controle mais L-NAME, n = 6-7]. Nenhum dos protocolos alterou a reatividade à noradrenalina de aortas com desnudamento. CONCLUSÃO: A obesidade induzida por dieta rica em gordura promove alterações metabólicas e vasculares. A alteração vascular envolveu uma melhora da via endotelial L-arginina/NO provavelmente relacionada à hiperinsulinemia e hiperleptinemia induzidas por dieta. A maior resistência aos efeitos do L-NAME na aorta de ratos obesos diz respeito a menor vulnerabilidade de indivíduos obesos na presença de patologias

    2008-08-01

    Full Text Available We report the clinical experience of one patient with perforated duodenal diverticulitis who was successfully treated by intra-abdominal drainage and feeding jejunostomy. A 53-year-old male patient visited our hospital due to acute onset of abdominal pain and distension. Physical examination revealed tenderness over the epigastric area and right-lower quadrant of the abdomen without obvious rebound tenderness or muscle guarding. Duodenal diverticulitis with a retroperitoneal abscess was identified by abdominal computed tomography scan. Surgical intervention was performed after the failure of conservative treatment. The operative findings were compatible with perforated duodenal diverticulitis, and intra-abdominal drainage of retroperitoneal abscess with simultaneous feeding jejunostomy was undertaken. The patient was doing well at the 4-month postoperative follow-up visit. We suggest the use of a conservative operative method, as opposed to conventional diverticulectomy and duodenorrhaphy, as an alternative approach for the management of this disorder, especially when conservative treatment has failed.

    Full Text Available Objective: The metabolic and cardiovascular risk of obesity is predominantly defined through the amount of intra-abdominal fat (IAF. Regarding this risk and the benefits of weight reduction gender-specific differences have been described. The aim of this study was to examine the gender-specific relationship between IAF assessed via ultrasound and the cardiometabolic risk profile in extremely obese adolescents before and after weight loss. Methods: In 107 consecutively admitted adolescents (n = 59 girls, mean age 15.4 ± 2.6 years boys and 15.1 ± 2.1 years girls, mean BMI z-score 3.2 ± 0.6 boys and 3.5 ± 0.6 girls anthropometric and fasting laboratory chemical parameters were measured before and after an in-patient long-term therapy (mean durance 5.6 ± 2.3 months. IAF was determined by measuring the intra-abdominal depth (IAD via ultrasound. Results: IAD was higher in boys as compared to girls (58.0 ± 22.4 mm vs. 51.3 ± 16.0 mm. IAD values were positively associated with BMI-z scores, waist circumferences, HOMA-IR and serum levels of γGT, hs-CRP and IL-6 in both genders. In boys, but not in girls, IAD was significantly correlated with systolic and diastolic blood pressure, serum levels of triglycerides, ALT as well as adiponectin and HDL-cholesterol. After a marked mean weight loss of -27.1 ± 16.2 kg (-20.1 ± 7.9% in boys and of -20.5 ± 11.5 kg (-17.3 ± 7.1% in girls, IAD decreased by -20.7 ± 16.2 mm (--32.4 ± 16.9% in boys and by -18.4 ± 12,7 mm (-34.3 ± 18.4% in girls, resulting in more pronounced ameliorations of cardiovascular risk factors in boys than in girls. Conclusions: The present study indicates that IAF assessed by ultrasound is a good indicator for the cardiometabolic risk factor profile in extremely obese adolescents. Associations between IAF and risk factors are more pronounced in boys than in girls.

    To assess the effect of mehanical ventilation (MV) guided by transpulmonary pressure (Ptp) on respiratory mechanics and gas exchange in severe acute pancreatitis patient with intraabdominal hypertension. Twelve severe acute pancreatitis patient with intraabdominal hypertension and acute respiratory distress syndrome(ARDS) underwent mechanical ventilation were involved from Jan to Dec 2013. PEEP levels were set to achieve a Ptp of 0 to 10 cm of water at end expiration. We also limited tidal volume to keep Ptp at less than 25 cm of water at end inspiration. Respiratory mechanics and gas-exchange were measured. Plat pressure (Pplat) increased and the compliance of chest wall (Ccw) decreased when intraabdominal pressure (IAP) increased. Pplat correlated with IAP positively (r2=0.741 9, P0.05). Compared with baseline, after guiding MV with Ptp, the Level of PEEP (14.6±4.2) cmH2O vs (8.3±2.0) cmH2O, and Ptp-e (1.5±0.5) cmH2O vs (-2.3±1.4) cmH2O increased (P0.05). Ptp-e correlated with PEEP (r2=0.549, P0.05). Compared with baseline, lung compliance (CL) (48.1±10.3) cmH2O vs (25.7±6.4) cmH2O and oxygenation index (PaO2/FiO2) (235±48) mmHg vs (160±35) mmHg improved obviously (P0.05). Transpulmonary pressure-directed mechanical ventilation in ARDS secondary to severe acute pancreatitis patient with intraabdominal hypertension could not only recruit the collapsed alveoli, improve lung compliance, increase oxygenation index and decrease dead space ventilation but also monitor lung stress to avoid alveoli overinflation, which might be lung protective.

    Full Text Available A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed. The histological diagnosis was an intra-abdominal desmoid tumor. A desmoid tumor is a fibrous soft tissue tumor arising in the fascia and musculoaponeurotic tissues. It usually occurs in the extremities and abdominal wall, and only rarely in the abdominal cavity. We experienced a case with an intra-abdominal desmoid tumor that was histologically diagnosed after laparotomy, which had been preoperatively diagnosed as an extragastric growing gastrointestinal stromal tumor. Although rare, desmoid tumors should be considered in the differential diagnosis of intra-abdominal tumors. Herein, we report this case with a literature review.

    Obesity is the main risk factor for obstructive sleep apnoea (OSA). The aim was to evaluate the long-term effect of continuous positive airway pressure (CPAP) on intraabdominal fat distribution in OSA patients. Fifty OSA patients with and 35 without CPAP treatment criteria were followed-up for 2 years. Visceral and subcutaneous adipose tissue (VAT and SAT) and preaortic intraabdominal fat (PIF) were assessed by sonography. In the non CPAP treated group, SAT and VAT mean values didn't change, while a significantly PIF growth was observed (55.19 [23.44] vs. 63.45 [23.94] mm, P=.021). In the CPAP treated group, VAT and PIF mean were not changed, while SAT decreased significantly (11.29 [5.69] vs. 10.47 [5.71] mm, P=.012). Long-term CPAP treatment produces intraabdominal fat redistribution and is associated with an anthropometric profile of lower cardiovascular risk in OSA patients.

    Perforated appendicitis can result in potentially serious complications requiring prolonged medical care. The optimal approach to successfully managing this condition is controversial. Review of 80 consecutive cases of pediatric acute perforated appendicitis with intra-abdominal infection (IAI) medically managed with parenteral antibiotics and percutaneous drainage (PD) during a 7-year period. All patients received broad spectrum parenteral antibiotic therapy. One-third were hospitalized for >2 weeks. IAI was identified on admission in 60% compared with developing during hospitalization in 40% of cases. Before performing PD, the mean duration of antibiotic therapy in those who developed IAI during hospitalization was 6 days. IAI cultures yielded 127 bacterial isolates; polymicrobial infection occurred in 65% of cases. Only 7% of aspirates were sterile. The most common pathogens were Escherichia coli (82%), of which 5 isolates exhibited extended-spectrum β-lactamase production, and streptococci (40%). At the time of PD, 60% were febrile (mean duration of in-hospital fever, 7.5 days); 67% defervesced within 24 hours after the procedure. Posthospitalization abdominal complications (recurrent IAI or appendicitis) occurred in one-third of patients. Children with perforated appendicitis and IAI often have a complicated and prolonged clinical course. Medical management consisting solely of parenteral antibiotic therapy is frequently ineffective in resolving IAI. Rapid clinical improvement commonly follows PD.

    Aims To describe intra-abdominal pressures (IAP) generated during Pilates Mat and Reformer activities, and determine whether these activities generate IAP above a sit-to-stand threshold. Methods Twenty healthy women with no symptomatic vaginal bulge, median age 43 (range 22 – 59 years), completed Pilates Mat and Reformer exercise routines each consisting of 11 exercises. IAP was collected by an intra-vaginal pressure transducer, transmitted wirelessly to a base station, and analyzed for maximal and area under the curve (AUC) IAP. Results There were no statistically significant differences in mean max IAP between sit-to-stand and any of the Mat or Reformer exercises in the study population. Six to twenty-five percent of participants exceeded their individual mean max IAP sit-to-stand thresholds for 10 of the 22 exercises. When measuring AUC from 0 cm H2O, half the exercises exceeded the mean AUC of sit-to-stand but only Pilates Reformer and Mat roll-ups exceeded the mean AUC of sit-to-stand when calculated from a threshold of 40 cm H2O (consistent with, for example, walking). Conclusion Our results support recommending this series of introductory Pilates exercises including five Mat exercises and six Reformer exercises to women desiring a low IAP exercise routine. More research is needed to determine the long term effects of Pilates exercise on post-surgical exercise rehabilitation and pelvic floor health. PMID:25672647

    Objective To evaluate the efficacy of methylene blue in preventing recurrent symptomatic postoperative adhesions. Methods Patients with a history of >2 surgeries for intra-abdominal adhesion-related complications were selected for this study. Adhesiolysis surgery was subsequently performed using administration of 1% methylene blue. The follow-up period was 28.5 ± 11.1 months. Results Data were available from 20 patients (seven men and 13 women) whose mean ± SD age was 51.2 ± 11.4 years. Adhesions took longer to become symptomatic after the first abdominal surgery when the initial pathology was malignant compared with benign. However, the recurrence of adhesions after a previous adhesiolysis surgery had a similar time onset regardless of the initial disease. Following adhesiolysis surgery with methylene blue, the majority of patients did not present with symptoms associated with adhesion complications (i.e., chronic abdominal pain, bowel obstruction) for the length of the follow-up period. Conclusions The use of methylene blue during adhesiolysis surgery appears to reduce the recurrence of adhesion-related symptoms, suggesting a beneficial effect in the prevention of adhesion formation.

    Full Text Available Introduction. Enterovesical fistula is rare and is often caused by bowel inflammatory diseases and tumours in the urinary bladder or the intestine with local infiltration of bowel or bladder, respectively. The fistula usually presents with lower urinary tract symptoms, pneumaturia, and faecaluria or with food particles in the urine. Intra-abdominal retained surgical foreign bodies have also been reported as causes. Case Presentation. A case of atypical presentation in a woman with enterovesical fistula following abdominal hysterectomy. Investigations confirmed the presence of surgical towel in the urinary bladder and a pair of artery forceps in the abdomen. The towel was removed at cystoscopy after which she presented with food particles in the urine. She later had laparatomy to remove the haemostat and to repair the fistula. Discussion. A typical presentation of enterovesical fistula delayed the diagnosis and treatment in this patient. Conclusion. Managing patients with recurrent urinary tract infection after abdominal operation should include appropriate imaging of the abdomen with emphasis on pelvic organs. Also, surgical operation should always be given the best shot the first time and strict operation room standards and guidelines should always be followed.

    2015-03-01

    Full Text Available Intra-abdominal infections are multifactorial and present an complex inflammatory response of the peritoneum to microorganisms followed by exudation in the abdominal cavity and systemic response Despite advances in management and critical care of patients with acute generalized peritonitis due to hollow viscus perforation, prognosis is still very poor, with high mortality rate. Early detection and adequate treatment is essential to minimize complications in the patient with acute abdomen. Prognostic evaluation of complicated IAI by modern scoring systems is important to assess the severity and the prognosis of the disease. Control of the septic source can be achieved either by nonoperative or operative means. Nonoperative interventional procedures include percutaneous drainages of abscesses. The management of primary peritonitis is non-surgical and antibiotic- treatment. The management of secondary peritonitis include surgery to control the source of infection, removal of toxins, bacteria, and necrotic tissue, antibiotic therapy, supportive therapy and nutrition. "Source control" is sine qua non of success and adequate surgical procedure involves closure or resection of any openings into the gastrointestinal tract, resection of inflamed tissue and drainage of all abdominal and pelivic collections.

    Applying appropriate positive end-expiratory pressure (PEEP) to corresponding intra-abdominal pressure (IAP) can improve gas exchange during capnoperitoneum without any hemodynamic effects. A total of 75 patients were randomly allocated to group 0PEEP (n=25), group 5PEEP (n=25), and group 10PEEP (n=25) according to the level of PEEP, in whom capnoperitoneum was created with IAP of 14, 8, and 14 mm Hg, respectively. Hemodynamic and respiratory parameters were recorded up to 30 minutes after capnoperitoneum. In 0PEEP group, mean end-tidal carbon dioxide demonstrated significant rise 2 minutes after capnoperitoneum and plateaued at about 15 minutes but remained at high level for up to 30 minutes when compared with the 5PEEP and 10PEEP groups (Phigher at 30 minutes when compared with 5PEEP (37.8±2.7 mm Hg) and 10PEEP (37.2±3.9 mm Hg) groups. The oxygenation was better preserved in 5PEEP and 10PEEP groups with significantly higher PaO2/Fio2 ratio. Heart rate, mean arterial pressure, and cardiac output remained stable throughout the study in all the 3 groups. Application of appropriate PEEP corresponding to the IAP helped maintain CO2 elimination and improved oxygenation without any hemodynamic disturbance in patients undergoing laparoscopic cholecystectomy.

    Intraperitoneal injection of H-4-II-E 2 tumor cells gave rise to a number of individually growing intraabdominal tumors concentrated at sites of high abdominal vascularization. During tumor growth, both tumor and intestinal crypt cell proliferative activity were progressively depressed. A linear reduction of [ 3 H]TdR incorporation occurred in individual tumors independent of tumor size, suggesting that total tumor burden determines the proliferative status of individual tumors. Cytokinetic jejunal crypt analyses indicated that both a reduction in crypt cellularity and an abbreviated cell cycle transit time were noted during the depression of proliferative activity in the jejunum. In tumor-bearing rats the migration rate of cells from the jejunal crypt through the villus was reduced in response to a reduction in total cell production in the crypt. The life span of the epithelial cell in both tumor-bearing and normal rats was similar due to a reduction in villus cellularity in the tumor-bearing animals. Following abdominal irradiation of the tumor, the magnitude, but not the time course of hyperproliferative intestinal recovery, was influenced by the tumor mass. For nontumor-bearing animals, maximal hyperproliferation (>200% of control) occurred 96 hr postradiation. With increasing tumor burden the compensatory proliferative response to radiation was progressively reduced

    Full Text Available Amebiasis is quite uncommon in developed countries. Its clinical presentation can vary from an asymptomatic carrier state to fulminant colitis and colonic perforation. We presented a 39-year-old female who received combined chemotherapy and radiotherapy for nasopharyngeal carcinoma 1 year prior to admission. Thereafter, she felt acute abdominal pain and diarrhea after traveling to Hainan 3 months ago. A physical examination of the patient revealed diffused peritoneal sign. Abdominal computed tomography showed a cecal tumor and intra-abdominal abscess. A subsequent exploratory laparotomy revealed an infiltrating yellowish tumor about 7 cm over the cecum and massive serous ascites. Pathology reported ambeic colitis with undermined ulcer and abscess formation of the cecum. Ameboma can be found in developed countries, particularly in patients with risk factors and a history of traveling to areas with the developing disease. Colonoscopy with biopsy is recommended for patients with suspected ameboma, and surgical intervention is likely indicated in complicated cases although the surgical mortality rate is high.

    Full Text Available Abstract Background Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of Klebsiella pneumoniae carbapenemase-producing bacteria is an emerging cause of abdominal infections. Case presentation We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by Klebsiella pneumoniae Sequence Type 258 producing K. pneumoniae carbapenemase 3 (KPC-Kp. In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection of a pancreatic pseudocystic lesion caused by KPC-Kp. In case 2, a 64-year-old HIV- negative Italian woman with pancreatic neoplasm and liver metastases developed a liver abscess due to KPC after surgery. Both women were admitted to our hospital but to different surgical units. The clonal relationship between the two isolates was investigated by pulsed-field gel electrophoresis (PFGE. In case 2, the patient was already colonized at admission and inter-hospital transmission of the pathogen was presumed. A long-term combination regimen of colistin with tigecycline and percutaneous drainage resulted in full recovery and clearance of the multidrug-resistant (MDR pathogen. Conclusions Timely microbiological diagnosis, the combined use of new and old antibiotics and radiological intervention appeared to be valuable in managing these serious conditions. The emergence and dissemination of MDR organisms is posing an increasing challenge for physicians to develop new therapeutic strategies and control and prevention frameworks.

    Acute appendicitis, especially if perforated at presentation, is often complicated by postoperative abscess formation. The detection of a postoperative abscess relies primarily on imaging. This has traditionally been done with contrast-enhanced computed tomography. Non-contrast magnetic resonance imaging (MRI) has the potential to accurately detect intra-abdominal abscesses, especially with the use of diffusion-weighted imaging (DWI). To evaluate our single-center experience with a rapid non-contrast MRI protocol evaluating post-appendectomy abscesses in children with persistent postsurgical symptoms. In this retrospective, institutional review board-approved study, all patients underwent a clinically indicated non-contrast 1.5- or 3-Tesla abdomen/pelvis MRI consisting of single-shot fast spin echo, inversion recovery and DWI sequences. All MRI studies were reviewed by two blinded pediatric radiologists to identify the presence of a drainable fluid collection. Each fluid collection was further characterized as accessible or not accessible for percutaneous or transrectal drainage. Imaging findings were compared to clinical outcome. Seven of the 15 patients had a clinically significant fluid collection, and 5 of these patients were treated with percutaneous drain placement or exploratory laparotomy. The other patients had a phlegmon or a clinically insignificant fluid collection and were discharged home within 48 h. Rapid non-contrast MRI utilizing fluid-sensitive and DWI sequences can be used to identify drainable fluid collections in post-appendectomy patients. This protocol can be used to triage patients between conservative management vs. abscess drainage without oral/intravenous contrast or exposure to ionizing radiation. (orig.)

    Chronic sepsis is always associated with profound wasting leading to increased release of amino acids from skeletal muscle. Net protein catabolism may be due to decreased rate of synthesis, increased rate of degradation, or both. To determine whether protein synthesis is altered in chronic sepsis, the rate of protein synthesis in vivo was estimated by measuring the incorporation of [ 3 H]-phenylalanine in skeletal muscle protein in a chronic (5-day) septic rat model induced by creation of a stable intra-abdominal abscess using an E. coli + B. fragilis-infected sterile fecal-agar pellet as foreign body nidus. Septic rats failed to gain weight at rates similar to control animals, therefore control animals were weight matched to the septic animals. The skeletal muscle protein content in septic animals was significantly reduced relative to control animals (0.18 +/- 0.01 vs. 0.21 +/- 0.01 mg protein/gm wet wt; p less than 0.02). The rate of incorporation of [ 3 H]-phenylalanine into skeletal muscle protein from control animals was 39 +/- 4 nmole/gm wet wt/hr or a fractional synthetic rate of 5.2 +/- 0.5%/day. In contrast to control animals, the fractional synthetic rate in septic animals (2.6 +/- 0.2%/day) was reduced by 50% compared to control animals (p less than 0.005). The decreased rate of protein synthesis in sepsis was not due to an energy deficit, as high-energy phosphates and ATP/ADP ratio were not altered. This decrease in protein synthesis occurred even though septic animals consumed as much food as control animals

    Although severely burned patients are at a high risk of developing intra-abdominal hypertension (IAH: IAP>12 mmHg) and Abdominal Compartment Syndrome (ACS) (IAP ≥ 20 mmHg), few data about its incidence and prevalence is available. Our aim was to determine the incidence and prevalence of IAH and ACS in patients with severe burns in our geographical setting. A pilot prospective, observational study was performed at the Burns Unit of the Plastic Surgery Department in Vall d'Hebron University Hospital (Barcelona), during a 12-month period. All patients with age ≥ 18 years old and burns >20% of the total body surface area (TBSA) were considered for inclusion. Patients who did not require urinary catheterization via the urethra were excluded. All patients included were followed during the first five days from their admission. Results are expressed as median (interquartile range) or frequency (percentage). During the study period, 303 patients were admitted to the Burns Unit. Twenty-five patients were included in the study (21 [84%] male, 4 [16%] female; age 42 [30-69 years]; TBSA burned 33 [25-58]%; all patients presented deep second-degree and/or third-degree burns). Eighteen (72%) patients met criteria for IAH, but only one (4%) developed ACS. The incidence of IAH and ACS was 0.56 and 0.04 cases/patient-day, respectively. Patients with IAH presented higher number of organs failure (2 [0-2.2] vs 0 [0-0]; p = 0.03). Patients with >20% TBSA burned presented a very high prevalence of IAH. Development of organ failure occurred even at moderately increased values of IAP. In this scenario, monitoring of IAP is the first step for establishing the importance of IAH/ACS in this patient population. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    Full Text Available Unaltered fat is a permanent component of the abdominal cavity, even in slim individuals. Visceral adiposity is one of the important factors contributing to diabetes, cardiovascular diseases and certain neoplasms. Moreover, the adipose tissue is an important endocrine and immune organ of complex function both when normal and pathological. Its role in plastic surgery, reconstruction and transplantology is a separate issue. The adipose tissue has recently drawn the attention of research institutes owing to being a rich source of stem cells. This review, however, does not include these issues. The identifi cation of fat is relatively easy using computed tomography and magnetic resonance imaging. It can be more diffi cult in an ultrasound examination for several reasons. The aim of this paper is to present various problems associated with US imaging of unaltered intra-abdominal fat located beyond organs. Based on the literature and experience, it has been demonstrated that the adipose tissue in the abdominal cavity has variable echogenicity, which primarily depends on the amount of extracellular fl uid and the number of connective tissue septa, i.e. elements that potentiate the number of areas that refl ect and scatter ultrasonic waves. The normal adipose tissue presents itself on a broad gray scale: from a hyperechoic area, through numerous structures of lower refl ection intensity, to nearly anechoic regions mimicking the presence of pathological fl uid collections. The features that facilitate proper identifi cation of this tissue are: sharp margins, homogeneous structure, high compressibility under transducer pressure, no signs of infi ltration of the surrounding structures and no signs of vascularization when examined with the color and power Doppler. The accumulation of fat tissue in the abdominal cavity can be generalized, regional or focal. The identifi cation of the adipose tissue in the abdominal cavity using ultrasonography is not always

    Full Text Available Polymicrobial intra-abdominal infections (IAIs are clinically prevalent and cause significant morbidity and mortality, especially those involving fungi. Our laboratory developed a mouse model of IAI and demonstrated that intraperitoneal inoculation with Candida albicans or other virulent non-albicans Candida (NAC species plus Staphylococcus aureus resulted in 70 to 80% mortality in 48 to 72 h due to robust local and systemic inflammation (sepsis. Surprisingly, inoculation with Candida dubliniensis or Candida glabrata with S. aureus resulted in minimal mortality, and rechallenge of these mice with lethal C. albicans/S. aureus (i.e., coninfection resulted in >90% protection. The purpose of this study was to define requirements for C. dubliniensis/S. aureus-mediated protection and interrogate the mechanism of the protective response. Protection was conferred by C. dubliniensis alone or by killed C. dubliniensis plus live S. aureus. S. aureus alone was not protective, and killed S. aureus compromised C. dubliniensis-induced protection. C. dubliniensis/S. aureus also protected against lethal challenge by NAC plus S. aureus and could protect for a long-term duration (60 days between primary challenge and C. albicans/S. aureus rechallenge. Unexpectedly, mice deficient in T and B cells (Rag-1 knockouts [KO] survived both the initial C. dubliniensis/S. aureus challenge and the C. albicans/S. aureus rechallenge, indicating that adaptive immunity did not play a role. Similarly, mice depleted of macrophages prior to rechallenge were also protected. In contrast, protection was associated with high numbers of Gr-1hi polymorphonuclear leukocytes (PMNLs in peritoneal lavage fluid within 4 h of rechallenge, and in vivo depletion of Gr-1+ cells prior to rechallenge abrogated protection. These results suggest that Candida species can induce protection against a lethal C. albicans/S. aureus IAI that is mediated by PMNLs and postulated to be a unique form of

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

    Although laparoscopic appendicectomy (LA) is an accepted alternative to the open appendicectomy (OA) approach, it has been suggested that there is a higher incidence of intraabdominal abscesses (IAAs). Our aim was to determine the incidence of IAA in 3 pediatric surgical centers routinely practicing both techniques. Data were collected retrospectively for pediatric patients undergoing LA or OA over an 8-year period. Analysis included IAA formation, appendicitis complexity, radiologic/histologic investigations, grade of surgeon, and wound infection. A total of 1267 appendicectomies were performed (514 LAs and 753 OAs). There was no difference between the incidences of IAA (LA, 3.9% [19/491] vs OA, 3.9% [28/714]; P = 1.0). The incidence of IAA was increased in those with complicated appendicitis (34/375 [9.1%] vs 13/830 [1.6%]; P ≤ .0001). There was an increased proportion of those with complicated appendicitis in the LA group (182/491 [37.1%] vs 193/714 [27.0%]; P = .0002). Surgical trainees were more likely to be the primary surgeon in the OA group (79% vs 63%; P = .0001), although the incidence of IAA did not correlate with grade of surgeon. There was no significant difference in incidence of wound infection between groups (LA, 4.6% [8/173] vs OA, 2.5% [18/377]; P = .93). This large retrospective study shows that the technique of appendicectomy does not appear to affect the incidence of IAAs. Patients with complicated appendicitis are more likely to develop an IAA regardless of technique. Crown Copyright © 2012. Published by Elsevier Inc. All rights reserved.

    Full Text Available Experimental studies suggest that intra-abdominal infection (IAI induces biological alterations that may affect the risk of lung infection.To investigate the potential effect of IAI at ICU admission on the subsequent occurrence of ventilator-associated pneumonia (VAP.We used data entered into the French prospective multicenter Outcomerea database in 1997-2011. Consecutive patients who had severe sepsis and/or septic shock at ICU admission and required mechanical ventilation for more than 3 days were included. Patients with acute pancreatitis were not included.Of 2623 database patients meeting the inclusion criteria, 290 (11.1% had IAI and 2333 (88.9% had other infections. The IAI group had fewer patients with VAP (56 [19.3%] vs. 806 [34.5%], P<0.01 and longer time to VAP (5.0 vs.10.5 days; P<0.01. After adjustment on independent risk factors for VAP and previous antimicrobial use, IAI was associated with a decreased risk of VAP (hazard ratio, 0.62; 95% confidence interval, 0.46-0.83; P<0.0017. The pathogens responsible for VAP were not different between the groups with and without IAI (Pseudomonas aeruginosa, 345 [42.8%] and 24 [42.8%]; Enterobacteriaceae, 264 [32.8%] and 19 [34.0%]; and Staphylococcus aureus, 215 [26.7%] and 17 [30.4%], respectively. Crude ICU mortality was not different between the groups with and without IAI (81 [27.9%] and 747 [32.0%], P = 0.16.In our observational study of mechanically ventilated ICU patients with severe sepsis and/or septic shock, VAP occurred less often and later in the group with IAIs compared to the group with infections at other sites.

Postoperative enteroparesis is usually accompanied by the raise of intra-abdominal pressure (IAP.Materials and methods. After approval of research by bioethics committee and informed consent 52 patients were prospectively divided in 2 groups depending on the type of postoperative intensive care. Patients underwent operations on abdominal cavity by laparotomy incision on the subject of peritonitis. Patient of the 1 (control group (n=27 after operation received stimulation of GIT with metoclopramide and simethicone.  In the 2 group (n=25 patients received metoclopramide and simethicone. Patients were comparable on age, sex, concomitant pathology, ASA class (IIE-IIIE and the type of operative intervention (laparotomy on the subject of peritonitis. IAP level was studied before operation and at 1,2,3 days after it. IAP was measured by indirect method trough the urinary bladder. The values recommended by the World society of abdominal compartment syndrome were considered as the normal IAP level.  Perfuse pressure (PP in abdominal cavity was calculated by formula: PP=MAP-ICP where MAP – mean arterial pressure. There were also studied indices of the central and peripheral hemodynamics, inflammation markers (leukocytes, fibrinogen level, IL-1α, TNFα, IL-10, leukocytic index of intoxication was calculated. The final point of research was 28 day after operation when we evaluated mortality and life quality on Rancho Los Amigos scale.Results and discussion. We registered the raise of IAP in 63.1% of patients. The value of intra-abdominal pressure exceeded an upper limit of the normal one by 58,5% (р <0,001. Among patients with high IAP 83% had intra-abdominal hypertension (IAH of 1 degree, 17% - of 2 degree.  The development of 3 and 4degree IAH were not observed before operation. PP remained within the normal.Correlative analysis

    Full Text Available Context: Bacterial isolates from intra-abdominal infections, in particular, peritonitis and their unpredictable antimicrobial resistance patterns, continue to be a matter of concern not only globally but regionally too. Aim: An attempt in the present study was made to study the patterns of drug resistance in bacterial isolates, especially gram negative bacilli in intra-abdominal infections (IAI in our hospital. Materials and Methods: From 100 cases of peritonitis, identification of isolates was done as per recommended methods. Antimicrobial susceptibility and extended-spectrum beta-lactamase (ESBL testing were performed following the CLSI guidelines. Results: A total of 133 clinical isolates were obtained, of which 108 were aerobes and 22 anaerobes. Fungal isolates were recovered in only three cases. Escherichia coli (47/108 emerged as the most predominant pathogen followed by Klebsiella spp. (27/108, while Bacteroides fragilis emerged as the predominant anaerobe (12/22. Among coliforms, 61.7% E. coli and 74.1% Klebsiella spp. were ESBL positive. A high level of resistance was observed for beta lactams, ciprofloxacin, amikacin, and ertapenem. Ertapenem resistance (30-41% seen in coliforms, appears as an important issue. Imipenem, tigecycline, and colistin were the most consistently active agents tested against ESBL producers. Conclusion: Drug resistance continues to be a major concern in isolates from intra-abdominal infections. Treatment with appropriate antibiotics preceded by antimicrobial resistance testing aided by early diagnosis, adequate surgical management, and knowledge of antibiotic - resistant organisms appears effective in reducing morbidity and mortality in IAI cases.

    Full Text Available Objectives: Resistin, a hormone secreted from adipocytes and considered to be a likely cause of insulin resistance, has recently been accepted as a proinflammatory cytokine. This study aimed to determine the correlation between resistin levels in patients with intra-abdominal sepsis and mortality. Methods: Of 45 patients with intraabdominal sepsis, a total of 35 adult patients were included in the study. This study was undertaken from December 2011 to December 2012 and included patients who had no history of diabetes mellitus and who were admitted to the general surgery intensive care units of Gazi University and Bülent Ecevit University School of Medicine, Turkey. Evaluations were performed on 12 patients with sepsis, 10 patients with severe sepsis, 13 patients with septic shock and 15 healthy controls. The patients’ plasma resistin, interleukin-6 (IL-6, tumour necrosis factor alpha (TNF-α, interleukin-1 beta (IL-1β, procalcitonin, lactate and glucose levels and Acute Physiology and Chronic Health Evaluation (APACHE II scores were studied daily for the first five days after admission. A correlation analysis of serum resistin levels with cytokine levels and APACHE II scores was performed. Results: Serum resistin levels in patients with sepsis were significantly higher than in the healthy controls (P <0.001. A significant correlation was found between serum resistin levels and APACHE II scores, serum IL-6, IL-1β, TNF-α, procalcitonin, lactate and glucose levels. Furthermore, a significant correlation was found between serum resistin levels and all-cause mortality (P = 0.02. Conclusion: The levels of resistin were significantly positively correlated with the severity of disease and were a possible mediator of a prolonged inflammatory state in patients with intra-abdominal sepsis.

    Full Text Available Marion J Skalweit1,2 1Department of Medicine, 2Department of Biochemistry, Louis Stokes Cleveland Department of Veterans Affairs and Case Western Reserve University School of Medicine, Cleveland, OH, USA Abstract: Drug-resistant pathogens have gained a foothold especially in the most vulnerable patient populations, hospitalized and immunocompromised individuals. Furthermore, extended-spectrum β-lactamase and carbapenemase-producing organisms are finding their way even into the community, with patients presenting to the hospital with established colonization and infection with resistant Enterobacteriaceae in particular. Recently, a novel antipseudomonal cephalosporin in combination with an established Class A β-lactamase inhibitor, ceftolozane/tazobactam has been approved by the FDA for use in the treatment of complicated urinary tract infections and complicated intra-abdominal infections. Ceftolozane is a uniquely potent antipseudomonal cephalosporin because of its high affinity for the penicillin-binding proteins of Pseudomonas aeruginosa, its low affinity for the intrinsic Class C β-lactamases of P. aeruginosa, its ability to enter P. aeruginosa through the outer membrane without the utilization of OprD protein, and the fact that it is not a substrate of the often upregulated MexAB/OprM efflux system of P. aeruginosa. The biological chemistry, pharmacokinetics/pharmacodynamics, microbiologic spectrum, and clinical trials that led to the approval of ceftolozane is reviewed. A discussion regarding its potential role in the treatment of complicated intra-abdominal infections and other infectious disease syndromes associated with drug-resistant pathogens follows.

    Bochdalek hernia (BH) is the most common type of congenital diaphragm hernia and is rarely seen in adults. In adult patients, BH often remains asymptomatic or presents with nondiagnostic symptoms and may lead to complications, though rarely. The necrosis and perforations occurring in the hernia may lead to mortality. In this report, we present a 34-year-old pregnant woman at 24 gestational weeks who presented with Bochdalek hernia causing gastric volvulus associated with perforation and intra-abdominal hemorrhage associated with splenic rupture.

    Full Text Available Abstract Background Acute pancreatitis leads to abdominal hypertension and compartment syndrome. Weeks after the episodes pancreatic fluids sometimes organize to pseudocysts, fluid collections by or in the gland. Aims of the present study were to evaluate the intra-abdominal pressure (IAP induced by large pancreatic pseudocysts and to examine the effect of their transcutaneous drainage on IAP. Methods Twenty seven patients with a pancreatic pseudocyst were included. Nine patients with pseudocysts greater than 1l (group A had CT drainage and eighteen (volume less than 1l were the control group. The measurements of group A were taken 6 hours before and every morning after the drainage, while for group B, two measurements were performed, one at the day of the initial CT and one 7 days after. Abdominal compliance (Cabd was calculated. Data were analyzed using student's t-test. Results Baseline IAP for group A was 9.3 mmHg (S.D. 1.7 mmHg, while the first post-drainage day (PDD IAP was 5.1 mmHg (S.D. 0.7 mmHg. The second PDD IAP was 5.6 mmHg (S.D. 0.8 mmHg, the third 6.4 mmH (S.D. 1.2 mmHgg, the fourth 6.9 mmHg (S.D. 1.6 mmHg, the fifth 7.9 mmHg (S.D. 1.5 mmHg, the sixth 8.2 mmHg (S.D. 1.4 mmHg, and the seventh 8.2 mmHg (S.D. 1.5 mmHg. Group B had baseline IAP 8.0 mmHg (S.D. 1.2 mmHg and final 8.2 mmHg (S.D. 1.4 mmHg. Cabd after drainage was 185.6 ml/mmHg (SD 47.5 ml/mmHg. IAP values were reduced between the baseline and all the post-drainage measurements in group A. IAPs seem to stabilize after the 5th post-drainage day. Baseline IAP was higher in group A than in group B, while the two values, at day 7, were equivalent. Conclusion The drainage of large pancreatic pseudocyst reduces IAP. Moreover, the IAP seems to rise shortly after the drainage again, but in a way that it remains inferior to the initial value. More chronic changes to the IAP are related to abdominal cavity's properties and have to be further studied.

    Only limited pharmacokinetic data are available for anidulafungin in ICU patients, especially in patients treated for severe intra-abdominal infection (IAI). This was a prospective multicentre observational study in ICU patients with suspected yeast IAI. All patients received an intravenous loading dose of 200 mg of anidulafungin, followed by 100 mg/day. Thirteen blood samples were drawn between day 1 and day 5 for pharmacokinetic analysis. Samples were analysed by an HPLC-tandem MS method. Demographics and SAPS2 and SOFA scores were recorded. Fourteen patients with a median age (IQR) of 62 years (48-70) and with a mean BMI of 30.5 kg/m 2 were included from three centres; 57.1% were women. Their median (IQR) SAPS2 score was 54 (45-67) and their median (IQR) SOFA score was 8 (7-12). Six patients with community-acquired IAI and eight patients with nosocomial-acquired IAI were included. Twelve yeasts were isolated: six Candida albicans , two Candida glabrata , two Candida tropicalis , one Candida parapsilosis and one Candida krusei . Pharmacokinetic parameters were as follows [mean (% coefficient of variation)]: C max (mg/L) = 6.0 (29%); T max (h) = 1.6 (25.8%); C min (mg/L) = 3.2 (36.8%); AUC 0-24 (mg·h/L) = 88.9 (38.6%); t 1/2 (h) = 42.1 (68.2%); CL (L/h) = 1.2 (42.3%); and V (L) = 72.8 (87.8%). A two-compartment model best described the anidulafungin concentrations in the population pharmacokinetic study. The pharmacokinetic parameters of anidulafungin in critically ill ICU patients with complicated IAI are similar to those observed in the literature. However, an increased V and a longer t 1/2 were observed in this study. (EudraCT No. 2010-018695-25). © The Author 2017.

This study is designed to provide a new scoring system for a better diagno- sis of IAI after blunt trauma. Methods: This prospective observational study was performed from April 2011 to October 2012 on patients aged above 18 years and suspected with blunt abdominal trauma (BAT admitted to the emergency department (ED of Imam Hussein Hospital and Shohadaye Hafte Tir Hospital. All patients were assessed and treated based on Advanced Trauma Life Support and ED protocol. Diagnosis was done according to CT scan findings, which was considered as the gold standard. Data were gathered based on patient's history, physical exam, ultrasound and CT scan findings by a general practitioner who was not blind to this study. Chisquare test and logistic regression were done. Factors with significant relationship with CT scan were imported in multivariate regression models, where a coefficient (β was given based on the contribution of each of them. Scoring system was developed based on the obtained total βof each factor. Results: Altogether 261 patients (80.1% male were enrolled (48 cases of IAI. A 24-point blunt abdominal trauma scoring system (BATSS was developed. Patients were divided into three groups including low (score<8, moderate (8≤score<12 and high risk (score≥12. In high risk group immediate laparotomy should be done, moderate group needs further assessments, and low risk group should be kept under observation. Low risk patients did not show positive CT-scans (specificity 100%. Conversely, all high risk patients had positive CT-scan findings (sensitivity 100%. The receiver operating characteristic curve indicated a close relationship between the results of CT scan and BATSS (sensitivity=99.3%. Conclusion: The present scoring system furnishes a

    Life-threatening intraabdominal candidiasis (IAC) occurs in 30 to 40% of high-risk surgical intensive care unit (ICU) patients. Although early IAC diagnosis is crucial, blood cultures are negative, and the role of Candida score/colonization indexes is not established. The aim of this prospective Fungal Infection Network of Switzerland (FUNGINOS) cohort study was to assess accuracy of 1,3-β-d-glucan (BG) antigenemia for diagnosis of IAC. Four hundred thirty-four consecutive adults with abdominal surgery or acute pancreatitis and ICU stay 72 hours or longer were screened: 89 (20.5%) at high risk for IAC were studied (68 recurrent gastrointestinal tract perforation, 21 acute necrotizing pancreatitis). Diagnostic accuracy of serum BG (Fungitell), Candida score, and colonization indexes was compared. Fifty-eight of 89 (65%) patients were colonized by Candida; 29 of 89 (33%) presented IAC (27 of 29 with negative blood cultures). Nine hundred twenty-one sera were analyzed (9/patient): median BG was 253 pg/ml (46-9,557) in IAC versus 99 pg/ml (8-440) in colonization (P equal to 80 pg/ml were 65 and 78%, respectively. In recurrent gastrointestinal tract perforation it was 75 and 77% versus 90 and 38% (Candida score ≥ 3), 79 and 34% (colonization index ≥ 0.5), and 54 and 63% (corrected colonization index ≥ 0.4), respectively. BG positivity anticipated IAC diagnosis (5 d) and antifungal therapy (6 d). Severe sepsis/septic shock and death occurred in 10 of 11 (91%) and 4 of 11 (36%) patients with BG 400 pg/ml or more versus 5 of 18 (28%, P = 0.002) and 1 of 18 (6%, P = 0.05) with BG measurement less than 400 pg/ml. β-Glucan decreased in IAC responding to therapy and increased in nonresponse. BG antigenemia is superior to Candida score and colonization indexes and anticipates diagnosis of blood culture-negative IAC. This proof-of-concept observation in strictly selected high-risk surgical ICU patients deserves investigation of BG-driven preemptive therapy.

    Appendicitis is the most common cause of an acute abdomen in children. With perforation, multiple intraperitoneal collections can be seen at presentation. In this situation, surgical treatment alone is rarely effective. To determine the role of image-guided drainage in treating patients with acute appendicitis complicated by multiple intraabdominal collections. A retrospective review of patient charts and interventional radiology records was performed to identify all patients with acute complicated appendicitis treated by multiple image-guided drainage procedures. Data reviewed included the number of drainages and aspirations performed, drain dwell time, the clinical course and temperature profile, and the length of inpatient hospital stay and any complications experienced. The study population comprised 42 children with a mean age of 107.6 months. A total of 100 drainage catheters were inserted and 56 aspirations were performed. Of the 42 children, 24 were successfully treated at a single sitting, while 18 returned for further intervention. The mean drain dwell time was 8.18 days. The mean inpatient stay was 15.02 days. Treatment of the acute presentation with image-guided intervention was successful in 92.3% of children. Successful management of acute perforated appendicitis with multiple intraabdominal abscesses can be achieved with multiple minimally invasive image-guided drainage procedures. (orig.)

    High intraabdominal pressure (IAP) during laparoscopic surgery has been associated with postoperative discomfort. Effects on nausea and access have not been subjected to randomized studies. In cholecystectomy, lower IAP may cause less pain, but nausea and surgical access in RYGB surgery have not been investigated. We studied the influence of two IAP levels on surgical access, operation time, postoperative pain, and nausea. Fifty consecutive female gastric bypass patients were randomized to intraabdominal pressure of 12 (IAP12) or 18 (IAP18) mm Hg. Surgeons and personnel were blinded to randomization; study groups were well matched for age and BMI. Operative time was noted in minutes. Visual analogue scales were used for assessing access and for patients assessing pain (abdomen-shoulder) and nausea (supine-standing) at six time points during the first 16 postoperative hours. Rescue medication was recorded. In 3/25 patients in the IAP12 group, the code was broken due to access problems vs. 0/25 in the IAP18 group (p = 0.1398). Operative time did not differ. Access was significantly better for IAP18 (92.2 ± 2.3 vs. 69.3 ± 4.2; p = 0.0001). Postoperative shoulder pain was maximal after 6 h but throughout less than in the abdomen (p effect on pain or nausea.

    Intra-abdominal hypertension (IAH) is a recognized prognostic marker for severity of severe acute pancreatitis (SAP) and has a strong impact on the clinical course of SAP. Previous studies indicate that a Da-Cheng-Qi Decoction (DCQD) is beneficial in the treatment of SAP. The purpose of this study was to evaluate the effect of modified DCQD on IAH in patients with SAP. Between January 2008 and December 2008, 42 patients from the West China Hospital were randomized into either the DCQD or control group (n = 21 in each group). Mortality, intra-abdominal pressure (IAP), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, C-reactive protein (CRP), oxygenation index, Balthazar CT score, rate of renal failure, decompression rate, intensive care unit (ICU) transfer rate, and length of hospital stay (LOS) were compared between the two groups. Compared to the control group, the modified DCQD treatment significantly decreased IAP (P < 0.05) and APACHE II (P < 0.05) scores on days 4 - 8, CRP on day 8 (P < 0.01), renal failure rate (P < 0.05), and LOS (P < 0.05). The oxygenation index was significantly improved in the DCQD group compared with the control group (P < 0.05). No significant differences in the Balthazar CT score, shock rate, ICU transfer rate, or mortality occurred between the two groups. The modified DCQD can effectively relieve IAH and decrease LOS for patients with SAP. Larger clinical trials are needed to confirm these findings.

    Pelvic inflammatory disease (PID) is frequent in adolescents and younger women. Diagnosis is usually based on the clinical findings, and the threshold for empiric antibiotic therapy should be low. However, at least in cases of resistance toward therapy or deterioration of symptoms, laparoscopic evaluation can be helpful. We searched the hospital charts for in-house patients who were treated for PID or tubo-ovarian abscess between 2007 and 2010. In cases with both vaginal and intra-abdominal bacterial cultures, results of those were compared. 73 patients with suspected PID or tubo-ovarian abscess were included. Median patients' age was 40 years (18-88), 18 of 73 (24.7 %) patients had an IUD at the time of consultation. 58 patients underwent laparoscopy or laparotomy. In 41 patients (70.7 %) tubo-ovarian abscess could be confirmed, four patients had differential gynecologic diagnoses, and two patients appendicitis. In vaginal swabs, most frequent bacteria were Streptococcus sp. (28.5 %), Escherichia coli (22.2 %), Enterococcus faecalis (15.9 %), and Staphylococcus sp. (9.5 %). In eight patients (11 %) Chlamydia trachomatis could be found, there was no case of Neisseria gonorrhea. In 33 patients both vaginal and abdominal cultures were available. In nine cases (27.3 %), identical bacteria could be found, however, 11 cases (33.3 %) showed different results. In severe cases of PID, laparoscopic evaluation and taking an intra-abdominal bacterial culture are helpful for the confirmation of diagnosis, accurate microbiologic testing and specific therapy.

    Technetium-99m-HM-PAO (({sup 99m}Tc)HM-PAO) leukocyte and indium-111-oxine (111In-oxine) leukocyte scanning were carried out simultaneously in 41 patients at 4 hr and 24 hr after reinjection to determine whether the 4-hr {sup 99m}Tc scan could replace the 24-hr {sup 111}In scan for detecting intraabdominal sepsis. Abdominal infection was confirmed in 12 cases. The 4-hr {sup 99}Tc-leukocyte scan, the 4-hr {sup 111}In-leukocyte scan, and the 24-hr {sup 111}In-leukocyte scan yielded a sensitivity of 100%, 67%, and 100%, respectively, and a specificity of 62%, 90%, and 86%, respectively. The 24-hr {sup 99m}Tc-leukocyte scan also produced a sensitivity of 100%, but it was falsely positive in all 29 cases without infection due to physiologic bowel uptake. False-positive 4-hr {sup 99m}Tc-leukocyte scans were also produced by physiologic bowel uptake in seven cases all of whom had true-negative 4-hr and 24-hr {sup 111}In-leukocyte scans. Because of the high incidence of false-positive 4-hr ({sup 99m}Tc)HM-PAO leukocyte scans, it was concluded that they could not replace 24-hr {sup 111}In-leukocyte scans for detecting intraabdominal sepsis, and that serial {sup 99m}Tc leukocyte scans starting earlier than 4 hr after reinjection must be evaluated.

    Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality. We evaluated the use of latent risk classes to predict the risk of major postoperative complications. An observational, retrospective cohort of patients undergoing intra-abdominal general surgery in the 2005 to 2010 American College of Surgeons National Surgical Quality Improvement Program was obtained. Known preoperative comorbidity and risk factor data were entered into LCA models to identify the latent risk classes. Complications were defined as: acute kidney injury, acute respiratory failure, cardiac arrest, deep vein thrombosis, myocardial infarction, organ space infection, pneumonia, postoperative bleeding, pulmonary embolism, sepsis/septic shock, stroke, unplanned reintubation, and/or wound dehiscence. Relative risk regression determined the associations between the latent classes and the 30-day complication risks, with adjustments for the surgical procedure. The area under the curve (AUC) of the receiver operator characteristic curve assessed model performance. LCA fit a 9-class model on 466,177 observations. The composite complication risk was 18.4% but varied from 7.7% in the lowest risk class to 56.7% in the highest risk class. After adjusting for procedure, the latent risk classes were significantly associated with complications, with risk ratios (95% confidence intervals) (compared to the class with the average risk) varying from 0.56 (0.54-0.58) in the lowest risk class to 2.15 (2.11-2.20) in the highest risk class, a 4-fold difference. In models incorporating surgical

    Intra-abdominal adhesions may result in an increased risk of major complications in case of a repeated cesarean section, such as bladder and bowel injury, hemorrhage, infection, and hysterectomy. In an attempt to predict intra-abdominal adhesions before a repeated cesarean delivery, we suggest the use of a novel technique employing a simple and feasible ultrasound imaging technique. The study included pregnant women who underwent one or more cesarean deliveries in their obstetric history and were evaluated during the third trimester of the ongoing pregnancy. In order to diagnose intra-abdominal adhesions, we used a sonographic sliding sign of the uterus under the inner part of the fascia of the abdominal muscles, and considered women 1) at high risk for severe adhesions in the absence of sonographic uterine sliding; or 2) at a low risk for severe adhesions in the presence of an obvious or moderate uterine sliding. A comparison between sonographic findings and intra-abdominal adhesions as evaluated by the surgeons during surgery was performed. We examined 63 patients with one or more previous cesarean delivery. Out of these 63 patients, 59 had completed the study and underwent repeated cesarean section at our Institution. In 16 out of the19 cases assigned to the high risk for severe adhesions group, the suspicion was confirmed at surgery, with a sensitivity of 76.2%. In addition, the suspicion for low risk for adhesions was confirmed in 35 out of 40 patients, with a specificity of 92.1%. The inter and intra-observer correlation using Cohen's Kappa (k) coefficient were 0.52 and 0.77 respectively. Our data show that a simple sonographic sign might predict both high and low risk for intra-abdominal adhesions in patients who underwent previous cesarean delivery. This technique may aid clinical decisions regarding repeated cesarean section approach. This article is protected by copyright. All rights reserved.

    To describe a case of severe intra-abdominal bleeding from omental implants after laparoscopic linear salpingostomy for ectopic pregnancy (EP). Case report. A medical center. A 27-year-old woman, presenting 15 days after methotrexate (MTX) treatment for persistent EP (35 days after laparoscopic linear salpingostomy for EP). Partial omentectomy. Serial β-hCG levels after partial omentectomy. Histopathologic examination confirmed omental pregnancy. Her β-hCG levels decreased rapidly from 1,673 mIU/mL to 1.35 mIU/mL within 14 days after partial omentectomy. Persistent EP after laparoscopic linear salpingostomy can occur in the omentum; meticulous clinical follow-up should be performed, especially when IM MTX injection was used as the salvage treatment for persistent EP.

    A 2.5-year-old, female opossum had acute stranguria. Based on radiography and ultrasonographic examination a cystic structure was identified in the caudal abdomen associated with bilateral hydroureter and hydronephrosis. This structure contained a neutrophilic fluid, determined to be urine. There was a neutrophilic leukocytosis. Serum chemistry values were within normal limits. The opossum was euthanized. An intra-abdominal fat pad incarceration of the urinary bladder above the trigone was present, resulting in complete obstruction of the urinary bladder and partial obstruction of the ureters. Vessels to the bladder were involved in the incarceration which resulted in vascular compromise and infarction of the bladder. Mild to moderate hydroureter and hydronephrosis were present.

    Abscess formation associated with intra-abdominal sepsis causes severe morbidity and can be fatal. Previous studies have implicated T cells in the pathogenesis of abscess formation, and we have recently shown that CD4(+) T cells activated in vitro by zwitterionic capsular polysaccharides from abscess-inducing bacteria such as Staphylococcus aureus and Bacteroides fragilis initiate this host response when transferred to naive rats. In this study, we show that mice deficient in alphabetaTCR-bearing T cells or CD4(+) T cells fail to develop abscesses following challenge with B. fragilis or abscess-inducing zwitterionic polysaccharides, compared with CD8(-/-) or wild-type animals. Transfer of CD4(+) T cells from wild-type mice to alphabetaTCR(-/-) animals reconstituted this ability. The induction of abscesses required T cell costimulation via the CD28-B7 pathway, and T cell transfer experiments with STAT4(-/-) and STAT6(-/-) mice demonstrated that this host response is dependent on STAT4 signaling. Significantly higher levels of IL-17, a proinflammatory cytokine produced almost exclusively by activated CD4(+) T cells, were associated with abscess formation in Th2-impaired (STAT6(-/-)) mice, while STAT4(-/-) mice had significantly lower levels of this cytokine than control animals. The formation of abscesses was preceded by an increase in the number of activated CD4(+) T cells in the peritoneal cavity 24 h following bacterial challenge. Confocal laser-scanning microscopy analysis revealed that CD4(+) T cells comprise the abscess wall in these animals and produce IL-17 at this site. Administration of a neutralizing Ab specific for IL-17 prevented abscess formation following bacterial challenge in mice. These data delineate the specific T cell response necessary for the development of intra-abdominal abscesses and underscore the role of IL-17 in this disease process.

    Full Text Available INTRODUCTION: Intra-abdominal hypertension (IAH is known as a common, serious complication in critically ill patients. Bacterial translocation and permeability changes are considered the pathophysiological bases for IAH-induced enterogenic endotoxemia and subsequent multiorgan failure. Nevertheless, the effects of slightly elevated intra-abdominal pressures (IAPs on the intestinal mucosa and the associated mechanisms remain unclear. METHODS: To investigate the acute effects of different nitrogen pneumoperitoneum grades on colonic mucosa, male Sprague-Dawley rats were assigned to six groups with different IAPs (0 [control], 4, 8, 12, 16, and 20 mmHg, n = 6/group. During 90 min of exposure, we dynamically monitored the heart rate and noninvasive hemodynamic parameters. After gradual decompression, arterial blood gas analyses were conducted. Thereafter, structural injuries to the colonic mucosa were identified using light microscopy. Colon permeability was determined using the expression of tight junction proteins, combined with fluorescein isothiocyanate dextran (FD-4 absorption. The pro-oxidant-antioxidant balance was determined based on the levels of malondialdehyde (MDA and antioxidant enzymes. RESULTS: IAH significantly affected the histological scores of the colonic mucosa, tight junction protein expression, mucosal permeability, and pro-oxidant-antioxidant balance. Interestingly, elevations of IAP that were lower than the threshold for IAH also showed a similar, undesirable effect. In the 8 mmHg group, mild hyponatremia, hypocalcemia, and hypoxemia occurred, accompanied by reduced blood and abdominal perfusion pressures. Mild microscopic inflammatory infiltration and increased MDA levels were also detected. Moreover, an 8-mm Hg IAP markedly inhibited the expression of tight junction proteins, although no significant differences in FD-4 permeability were observed between the 0- and 8-mmHg groups. CONCLUSIONS: Acute exposure to slightly

    A alta ingestão calórica favorece o acúmulo de gordura corporal. Adicionalmente, evidências sugerem que uma maior ingestão proteica pode auxiliar no controle do peso corporal. Assim, objetivou-se neste estudo avaliar a ingestão calórica e as relações entre ingestão proteica e variáveis de adiposidade em mulheres adultas. Determinou-se o Índice de Massa Corporal (IMC, a circunferência da cintura (CC e o percentual de gordura corporal (%GC. A ingestão calórica e proteica foi avaliada utilizando três recordatórios de 24 horas. Foram feitas correlações entre IMC, CC e %GC, e ingestão proteica. A ingestão média de calorias representou 88,36% das necessidades estimadas, mas os valores de IMC foram compatíveis com ingestão calórica excessiva em longo prazo para 42,8% das voluntárias. A ingestão proteica (g foi superior (p<0,05 nas eutróficas em comparação às com excesso de peso. Nenhuma diferença em calorias desse macronutriente foi observada entre as mesmas. Correlação signifi cativa não foi encontrada entre as variáveis analisadas. Portanto, sugere-se que, para haver efeito na adiposidade, a ingestão calórica de proteínas deve ser ≥ 25% da ingestão calórica diária, o que não foi verifi cado, já que a maioria consumiu menos de 20%. Erros inerentes ao método de avaliação da ingestão alimentar também podem explicar em parte esses resultados.

    Full Text Available Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient’s condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage. The patient improved and was discharged in satisfactory condition. Endoscopic ultrasound-guided drainage is a treatment option for patients with intra-abdominal abscess following gastric perforation due to ramucirumab.

Although not an antibiotic in a new class, it offers a glimmer of hope in combating serious infections secondary to multidrug-resistant Gram-negative bacteria when we have not seen a new class of antibacterial, particularly for Gram-negative bacteria, for more than 10 years. In vitro, doripenem exhibits a broad spectrum of activity against Gram-positive and Gram-negative bacteria, including extended-spectrum β-lactamase (ESBL and Amp-C β-lactamase producing Enterobacteriaceae and anaerobes. Doripenem also exhibits better in vitro activity against Pseudomonas aeruginosa compared to other anti-pseudomonal carbapenems. It combines the desirable activities of both imipenem and meropenem. It has similar activity to imipenem against Gram-positive pathogens and has the antimicrobial spectrum of meropenem against Gram-negative organisms. Several randomized clinical trials have demonstrated that doripenem is non-inferior to meropenem, imipenem, piperacillin/tazobactam, or levofloxacin in its efficacy and safety profile in treating a wide range of serious bacterial infections including intra-abdominal infection, complicated urinary tract infection, and nosocomial pneumonia. Due to its wide spectrum of activity and good safety profile it is susceptible to misuse leading to increasing rates of resistance

    Severely burned patients have altered drug pharmacokinetics (PKs), but it is unclear how different they are from those in other critically ill patient groups. The aim of the present study was to compare the population pharmacokinetics of micafungin in the plasma and burn eschar of severely burned patients with those of micafungin in the plasma and peritoneal fluid of postsurgical critically ill patients with intra-abdominal infection. Fifteen burn patients were compared with 10 patients with intra-abdominal infection; all patients were treated with 100 to 150 mg/day of micafungin. Micafungin concentrations in serial blood, peritoneal fluid, and burn tissue samples were determined and were subjected to a population pharmacokinetic analysis. The probability of target attainment was calculated using area under the concentration-time curve from 0 to 24 h/MIC cutoffs of 285 for Candida parapsilosis and 3,000 for non-parapsilosis Candida spp. by Monte Carlo simulations. Twenty-five patients (18 males; median age, 50 years; age range, 38 to 67 years; median total body surface area burned, 50%; range of total body surface area burned, 35 to 65%) were included. A three-compartment model described the data, and only the rate constant for the drug distribution from the tissue fluid to the central compartment was statistically significantly different between the burn and intra-abdominal infection patients (0.47 ± 0.47 versus 0.15 ± 0.06 h−1, respectively; P burn patients and intra-abdominal infection patients. After the first dose, micafungin at 100 mg/day achieved the PK/PD targets in plasma for MIC values of ≤0.008 mg/liter and ≤0.064 mg/liter for non-parapsilosis Candida spp. and Candida parapsilosis species, respectively.

    Some patients with refractory peritoneal dialysis-related peritonitis continue to develop intra-abdominal complications despite removal of the peritoneal catheter. Repeated percutaneous drainage or open laparotomy is often required, and mortality is not uncommon. The benefits of pelvic drainage placement during catheter removal in decreasing these complications and interventions remain unproven. Forty-six patients with refractory peritonitis who underwent removal of a Tenckhoff catheter between 1991 and 2013 were reviewed retrospectively. Twelve patients had pelvic drainage using closed active suction devices during catheter removal (drainage group). The remaining 34 patients underwent catheter removal without drainage (non-drainage group). The outcomes measured were the development of intra-abdominal complications and the requirement for repeated percutaneous drainage or open laparotomy within 90 days after the catheter removal. Baseline characteristics were similar with the exception of a higher median number of previous peritonitis episodes in the drainage group compared with the non-drainage group (2 vs 0, P = 0.02). During the follow-up period, intra-abdominal complications occurred in 15 (44%) of 34 patients in the non-drainage group, compared with one (8%) of 12 patients in the drainage group (P = 0.03). Twelve (35%) patients in the non-drainage group required repeated percutaneous drainage or open laparotomy for management, compared with zero (0%) patients in the drainage group (P = 0.02). Drain tubes were removed at a median of 6 days (inter-quartile range: 5-10) without complications. In the management of refractory peritonitis, pelvic drainage during removal of dialysis catheter decreases the risk of subsequent intra-abdominal complications and invasive interventions. © 2015 Asian Pacific Society of Nephrology.

We explored the mechanisms of this reduction by studying the turnover of Lp A-I and Lp A-I/A-II in postmenopausal women well characterized for total body, regional and sub-regional adiposity by body mass index (BMI), truncal girth ratio, and abdominal magnetic resonance imaging (MRI), respectively. We tested for possible cause-effect relationships by measuring inter-correlations among these variables. Intra-abdominal fat area correlated strongly and positively with the fractional catabolic rate (FCR) of Lp A-I (r=0.98, P=0.003). Intra-abdominal fat only showed a non-significant trend toward correlation with the FCR of Lp A-I/A-II (r=0.84, P=0.07), and had no correlation with the production or transport rate (TR) of either Lp A-I or Lp A-I/A-II (r=0.48 and 0.02, respectively, P>0.1). Subjects were studied both with and without estrogen replacement, allowing exploration of a possible interaction of adiposity with estrogen effects on HDL turnover. Response of HDL turnover to estrogen did not correlate with adiposity, except for a parameter of waist to hip ratio (WHR), which predicted the increase in LP A-I TR with estrogen (r=0.84, P=0.04). We conclude that intra-abdominal fat may lower HDL levels by increasing the FCR of Lp A-I, suggesting a mechanism by which central adiposity may be proatherogenic.

    Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is the best operative treatment currently available for patients with peritoneal carcinomatosis of ovarian origin. The open abdomen technique is the classic technique for hyperthermic intraperitoneal chemotherapy. We developed a closed abdomen model that improves temperature control and increases exposure of peritoneal surfaces to the drug by recirculating the perfusate. We used a porcine model with 12 female, Large White pigs-4 in the open technique group and 8 in the closed technique CO2 group. We performed cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for 60 minutes using paclitaxel (175 mg/m(2)) at an input temperature of 42°C. Perfusate recirculation was performed under controlled pressure (range, 12-15 mmHg). The infusion of 0.7 L of CO2 via a separate intraperitoneal infusion catheter mixed the perfusate within the peritoneal cavity. Intra-abdominal temperature was assessed using 6 intra-abdominal temperature probes and 2 temperature probes in the inflow and outflow circuits. Drug distribution was assessed using methylene blue staining. Intra-abdominal temperatures remained constant and homogeneous in all intra-abdominal quadrants with a constant input temperature of 42°C and a minimum output temperature of 41.4°C. The infused CO2 caused the fluid to bubble and created agitation inside the abdominal cavity to facilitate a homogeneous distribution of the drug-containing perfusate. The closed recirculation hyperthermia with intraperitoneal chemotherapy technique developed in this study is safe and feasible, and may provide a more homogeneous delivery of heated chemotherapy to the peritoneal cavity in patients with peritoneal malignancies.

    Rimonabant, the first selective cannabinoid type 1 (CB1) receptor antagonist, improves cardiometabolic risk factors in overweight/obese patients. ADAGIO-Lipids assessed the effect of rimonabant on cardiometabolic risk factors and intraabdominal and liver fat. 803 abdominally obese patients with atherogenic dyslipidemia (increased triglycerides [TG] or reduced high-density lipoprotein-cholesterol [HDL-C]) were randomized to placebo or rimonabant 20 mg/d for 1 year. HDL-C and TG were coprimary end points. Intraabdominal (visceral) and liver fat were measured by computed tomography in a subgroup of 231 patients. In total, 73% of rimonabant- and 70% of placebo-treated patients completed the study treatment. Rimonabant 20 mg produced significantly greater changes from baseline versus placebo in HDL-C (+7.4%) and TG levels (-18%; PA1 and B, HDL2, HDL3, C-reactive protein, and adiponectin levels (all Pblood pressure were significantly reduced with rimonabant versus placebo (P<0.0001). The safety profile of rimonabant was consistent with previous studies; gastrointestinal, nervous system, psychiatric, and general adverse events were more common with rimonabant 20 mg. In abdominally obese patients with atherogenic dyslipidemia, rimonabant 20 mg significantly improved multiple cardiometabolic risk markers and induced significant reductions in both intraabdominal and liver fat.

    Full Text Available The primary and metastatic gastrointestinal synovial sarcoma is rare with a wide differential diagnosis. It usually expresses cytokeratins EMA, BCL2 with an occasional CD99, and S100 positivity but not desmin. We present a case of metastatic synovial sarcoma with unusual immunophenotype causing diagnostic challenges. The tumor cells showed focal cytokeratin, EMA, and, unexpectedly, desmin positivity. Additional intranuclear TLE-1 positivity and negativity for CD34 and DOG-1 were also identified. A diagnosis of monophasic synovial sarcoma was confirmed by using FISH break-apart probe. RT-PCR revealed the SYT-SSX1 fusion gene. Intra-abdominal synovial sarcoma, either primary or metastatic, with unusual desmin positivity raises the diagnostic challenge, since a wide range of differential diagnoses could show a similar immunophenotype (leiomyosarcoma, desmoid tumor, myofibroblastic tumor, and rarely GIST etc.. Typical morphology and focal cytokeratin/EMA positivity should alert to this tumor, and FISH and RT-PCR remain the gold standard for the confirmation.

    Recent systematic reviews have suggested an increased incidence of intraabdominal abscess (IAA) formation following laparoscopic appendicectomy (LA) compared with the open approach (OA). As the majority of these analyses have focused on appendicectomy in adults, our aim was to review the evidence base for pediatric patients. We performed a comprehensive review of relevant studies published between 1990 and 2012. Specific inclusion and exclusion criteria were used to identify studies that investigated the incidence of IAA following LA and OA in pediatric patients. The primary outcome measure in the present meta-analysis was IAA formation, and secondary outcomes included wound infection (WI) and incidence of postoperative small bowel obstruction (SBO). Sixty-six studies with a total of 22,060 pediatric patients were included: 56.5% OA and 43.5% LA. There was no overall difference in the incidence of IAA formation: 2.7% for OA (333/12,460) versus 2.9% for LA (282/9600) (P=.25). However, OA patients had a higher incidence of wound infection: 3.7% for OA (337/9228) versus 2.2% for LA (183/8154) (PLA: 0.4% LA (86/5767) versus 1.5% (29/6840) (PLA versus OA in pediatric patients. LA confers a significantly lower risk of other postoperative complications, including WI and SBO.

    Damage control surgery (DCS) was developed to manage exsanguinating trauma patients, but is increasingly applied to the management of peritoneal sepsis and abdominal catastrophes. Few manuscripts compare the outcomes of these surgeries on disparate patient populations. A multi-institutional three group propensity score matched case cohort study comparing penetrating trauma (PT-DCS), blunt trauma (BT-DCS), and intraperitoneal sepsis (IPS-DCS) was performed comparing patients treated with DSC between 2008 and 2013. Propensity scoring was performed using demographic and presenting physiologic data. Four hundred and twelve patients were treated with DCS across two institutions. Propensity matching for age, gender, and initial Acute Physiology and Chronic Health Evaluation II score 80 identified 80 patients per group for comparison. Rate of primary fascial closure was lowest in the IPS-DCS group, and highest in the penetrating trauma DCS group. Intra-abdominal complication rates were highest in the IPS-DCS group. IPS-DCS had increased time to definitive closure compared with the other two groups (RR 1.8; 1.3-2.2; P eight days were more than twice the risk of death at 90 days across all groups.

    Prosthetic mesh is used frequently in abdominal wall hernia reconstruction but is prone to postoperative adhesion formation. Complications resulting from intra-abdominal adhesions represent a considerable clinical and cost burden. We, herein, investigate the antiproliferative and antiadhesiogenic properties of sirolimus and hydrogel-impregnated, drug-eluting mesh to decrease such complications in a mouse model of abdominal wall hernia repair. A 1 × 1cm(2) polypropylene mesh from 1 of 3 groups (group 1, plain control; group 2, hydrogel [2% agarose]; and group 3, hydrogel + 10 mcg sirolimus) was implanted operatively into the peritoneal cavity of BALB/c mice and followed for up to 4 weeks. Adhesions were scored by percent surface area of mesh (range, 0-100%), severity (range, 0-3), and tenacity (range, 0-4). Representative samples were assessed by scanning electron microscopy. Mesh impregnated with the combination of hydrogel and sirolimus led to a significant decrease in adhesion formation. The percent surface area of adhesional attachment to mesh was decreased from 100.0 ± 0% in the plain mesh control group versus 18 ± 8% (P model, was well tolerated without side effects, and has potential for clinical application.

    Full Text Available Gastrointestinal stromal tumors (GISTs in adolescence are far less common than adult GISTs and have varied GIST genotypes that present diagnostic and therapeutic challenges. Here, we discuss a 21-year-old male with diagnosis of unresectable, imatinib-resistant GIST. At initial evaluation, a neoadjuvant treatment approach was recommended. As such, the patient received imatinib over the course of one year. Unfortunately, the GIST increased in size, and a subsequent attempt at surgical resection was aborted fearing infiltration of major vascular structures. The patient was then referred to our institution, at which time imatinib therapy was discontinued. Surgical intervention was again considered and the patient underwent successful resection of massive intra-abdominal GIST with total gastrectomy and Roux-en-Y esophagojejunostomy. Since pediatric GISTs are typically resistant to imatinib, we performed genotype analysis of the operative specimen that revealed KIT mutations associated with imatinib sensitivity and resistance. Given the sequencing data and operative findings, the patient was started postoperatively on sunitinib. This case illustrates the importance of understanding both adult and pediatric GISTs when implementing appropriate treatment regimens. Since the genotype of GISTs dictates phenotypic behavior, mutational analysis is an important component of care especially for adolescents whose disease may mirror the pediatric or adult population.

    Full Text Available We have previously shown that physical activity predicts intra-abdominal adipose tissue (IAT, but it is unknown whether energy intake predicts IAT independently of physical activity in a community-based, naturalistic environment. The association of energy intake with IAT was explored cross-sectionally in women, recruited between 2002 and 2005 for a study of fat patterning in midlife. IAT at L4-L5 vertebral interspace was assessed by computed tomography, energy intake by the Block Food Frequency Questionnaire, and physical activity by the Kaiser Physical Activity Survey. Linear regression models were used for the principal analyses. Among the 257 women, 48% were African American and 52% were Caucasian. Women were 52±3 years old, and 49% were postmenopausal. Every 500 kcal increase in energy intake was associated with a 6% higher IAT (P=0.02, independent of physical activity (P=0.02, after adjustment for ethnicity, menopausal status, age, smoking, income, and DXA-assessed percent body fat. Energy intake had a significant interaction with ethnicity (P=0.02, but not with physical activity. Models using the IAT to subcutaneous abdominal adipose tissue ratio as an outcome had similar associations. In conclusion, self-reported EI was associated with preferential IAT accumulation in midlife women, independent of physical activity. This association was significantly stronger in Caucasian than African American women. Future longitudinal studies are needed to explore lifestyle predictors of IAT accumulation during the menopausal transition.

    The aim of this study was to evaluate the impact of preoperative hypoalbuminemia on the development of intra-abdominal septic complications (IASCs) after primary anastomosis for patients with Crohn's disease (CD). All CD patients undergoing bowel resection with a primary anastomosis during the study period from 2007 to 2015 were enrolled. The association of preoperative hypoalbuminemia (preoperative albumin level. Preoperative hypoalbuminemia occurred in 13 (11.7%) patients. The duration from diagnosis to surgery was longer for patients with preoperative hypoalbuminemia than those without ( p = 0.012). Patients with preoperative hypoalbuminemia were more likely to have a history of preoperative use of 5-aminosalicylic acid ( p = 0.013) and have an intraoperative finding of small bowel obstruction ( p = 0.015). Of all patients, 24 (19.4%) developed postoperative IASCs. Univariate analysis showed that patients with preoperative hypoalbuminemia had an increased risk for IASCs ( p = 0.012). Multivariate analysis confirmed the association between preoperative hypoalbuminemia and IASCs (odds ratio 4.67, 95% confidence interval: 1.28-17.04, p = 0.02). Similar findings were also obtained when preoperative albumin level was analysed as a continuous variable ( p = 0.019). Preoperative hypoalbuminemia is a significant predictor for the development of postoperative IASCs in CD patients after bowel resection with a primary anastomosis. Favorable preoperative nutrition status might lessen the risk for IASCs.

    CD3+, CD4+ and CD8+ T cells, B cells, and NK cells. In both studied groups (i.e. IAS and PDS, the
    WBC was elevated. However, it was significantly higher in the IAS group than in the PDS group. The difference
    was due to a lower granulocyte count, as well as a lower monocyte count in PDS. We found no significant
    correlation between the total lymphocyte number and CD3+CD8+ T cells in either form of sepsis. Similarly, we
    observed no correlation between the total lymphocyte number and the NK cells subset in IAS. However, the
    numbers of CD3+CD8+ and NK cells correlated similarly in both types of sepsis. Both studied types of sepsis
    induced profound lymphocytopenia, with marked loss of CD8+ T cells and the NK cells. However, the similar
    relation between them, which was independent of the infection type, suggests that the NK and CD3+CD8+ cells
    have shared mechanisms of regulation. The primary site of infection has an impact on the global immune reaction.
    These alternations include especially myeloid cells: granulocytes and monocytes which disappear from peripheral

MÉTODOS: Oito porcos Agroceres foram submetidos, após a instrumentação, a cinco cenários clínicos: 1 estado basal com baixa pressão intra-abdominal e pulmão sadio; 2 pneumoperitôneo, com pressão intra-abdominal de 20 mm Hg; 3 lesão pulmonar aguda induzida por lavagem pulmonar e desativação de surfactante; 4 pneumoperitôneo com pressão intra-abdominal de 20 mm Hg na vigência de lesão pulmonar aguda e com PEEP baixo; e 5 PEEP ajustado a 27 cm H2O na vigência de pneumoperitôneo e lesão pulmonar aguda. Variáveis respiratórias e hemodinâmicas foram coletadas. Análise multivariada foi realizada buscando as variáveis associadas com elevação da pressão intracraniana nos cinco cenários estudados. RESULTADOS: Após a análise multivariada, nas situações não associadas com lesão pulmonar aguda apenas a pressão de platô das vias aéreas se correlacionou positivamente com a pressão intracraniana. Nos modelos associados com lesão pulmonar aguda, a pressão de platô de vias aéreas, a pressão arterial de CO2, o CO2 no final da expiração e a pressão venosa central se correlacionaram positivamente com incrementos da pressão intracraniana. CONCLUSÃO: Em um modelo de disfunção orgânica múltipla com situações clínicas associadas com aumento da pressão torácica e abdominal, o incremento da pressão intracraniana desencadeado pela elevação da pressão abdominal parece ser decorrente da piora da complacência do sistema respiratório e da redução do gradiente para drenagem venosa cerebral ocasionado pela elevação da pressão venosa central.OBJECTIVE: To evaluate the effects of hemodynamic, respiratory and metabolic changes on intracranial pressure in a model of acute lung injury and abdominal compartment syndrome

    Full Text Available Abstract The CIAO Study is a multicenter observational study currently underway in 66 European medical institutions over the course of a six-month study period (January-June 2012. This preliminary report overviews the findings of the first half of the study, which includes all data from the first three months of the six-month study period. Patients with either community-acquired or healthcare-associated complicated intra-abdominal infections (IAIs were included in the study. 912 patients with a mean age of 54.4 years (range 4–98 were enrolled in the study during the first three-month period. 47.7% of the patients were women and 52.3% were men. Among these patients, 83.3% were affected by community-acquired IAIs while the remaining 16.7% presented with healthcare-associated infections. Intraperitoneal specimens were collected from 64.2% of the enrolled patients, and from these samples, 825 microorganisms were collectively identified. The overall mortality rate was 6.4% (58/912. According to univariate statistical analysis of the data, critical clinical condition of the patient upon hospital admission (defined by severe sepsis and septic shock as well as healthcare-associated infections, non-appendicular origin, generalized peritonitis, and serious comorbidities such as malignancy and severe cardiovascular disease were all significant risk factors for patient mortality. White Blood Cell counts (WBCs greater than 12,000 or less than 4,000 and core body temperatures exceeding 38°C or less than 36°C by the third post-operative day were statistically significant indicators of patient mortality.

    To investigate the role of increased intra-abdominal pressure (IAP) on the intratumoral accumulation and the antitumor effect of intraperitoneal cisplatin in rats with advanced peritoneal carcinomatosis. To evaluate the tolerance of IAP in pigs, as it is a large animal with a body size equivalent to humans. To investigate if an active convection, driven by a positive IAP, increases cisplatin penetration and antitumor effectiveness in a model of advanced peritoneal carcinomatosis in rats. BDIX rats with macroscopic peritoneal tumors received cisplatin administered as intravenous injection (IV), conventional intraperitoneal injection (IP), or sustained intraperitoneal injection of cisplatin given in a large volume of solvent for maintaining IAP for 1 hour. Platinum tissue concentration was measured by atomic absorption spectroscopy (AAS), and platinum distribution into the tumor nodules was assessed by the particular-induced x-ray emission (PIXE) method. The antitumor effect was assessed in a survival experiment. The hemodynamic, local, and systemic tolerance of IAP, with or without cisplatin, was evaluated in Large White pigs. The maximum tolerated IAP was 22 mm Hg for 1 hour in nonventilated rats. IAP, in comparison with IV or conventional IP injections, resulted in the increased concentration and depth of diffusion of platinum into diaphragm and peritoneal tumor nodules. Consequently, IAP treatment induced an extended survival of rats treated at an advanced stage of carcinomatosis. In 7 50- to 70-kg ventilated pigs, a 40-mm Hg IAP was well tolerated when maintained stable for 2 hours. Renal failure occurred in pigs receiving a total dose of 200 and 400 mg of cisplatin with IAP, but a dose of 100 mg was well tolerated. Intraperitoneal chemotherapy with increased IAP, in comparison with conventional IP or IV chemotherapy, improved the tumor accumulation and the antitumor effect of cisplatin in rats bearing advanced peritoneal carcinomatosis.

    The aim of the study was to describe the characteristics of cirrhotic patients with candidemia and intra-abdominal candidiasis (IAC) and to evaluate the risk factors associated with 30-day mortality. A multicenter multinational retrospective study including all consecutive episodes of candidemia and IAC in adult patients with liver cirrhosis in 14 European hospitals during the period 2011-2013 was performed. A total of 241 episodes (169 candidemia, 72 IAC) were included. Most Candida infections were acquired in hospital (208, 86.3%), mainly in the intensive care unit (ICU) (121, 50.2%). At clinical presentation, fever was seen in 60.6% of episodes (146/241) and septic shock in 34.9% (84/241). C. albicans was the most common species (found in 131 episodes, 54.4%), followed by C. glabrata (35, 14.5%) and C. parapsilosis (34, 14.1%). Overall, the 30-day mortality was 35.3%. Multivariable analysis identified candidemia (OR 2.2, 95% CI 1.2-4.5) and septic shock (OR 3.2, 95% CI 1.7-6) as independent factors associated with 30-day mortality. Adequate antifungal treatment (OR 0.4, 95% CI 0.3-0.9) was associated with survival benefit. A shift towards increasing prevalence of C. glabrata and C. parapsilosis species in patients with liver disease was documented. Candidemia and IAC were associated with significant mortality in cirrhotic patients. Thirty-day mortality was associated with candidemia and severe clinical presentation, whereas adequate antifungal treatment improved the prognosis.

    To report the occurrence of intra-abdominal injury (IA) in dogs with pelvic fractures due to blunt trauma, to evaluate for association between characterization of pelvic fractures and the presence of IA, and to evaluate for association between IA and other specific clinical conditions. Retrospective case series (2008-2013). University teaching hospital. Eighty-three client-owned dogs with pelvic fractures due to blunt trauma. None. Pelvic injuries included pubic fractures (90.4%), ischial fractures (80.7%), sacroiliac luxations (57.8%), iliac fractures (43.4%), acetabular fractures (30.1%), and sacral fractures (13.3%). Thirty-one dogs (37%) had IA, which included hemoabdomen (27 dogs), uroabdomen (3), and septic abdomen (3); 2 dogs had 2 types of IA. Dogs with sacral fractures were significantly more likely to have IA than dogs without sacral fractures (P = 0.0162). Characterization of pelvic fractures included the direction of compression, presence of a weight-bearing bone fracture, and degree of pelvic narrowing, none of which had an association with IA (P > 0.05). Dogs were more likely to have IA if they had cardiac dysrhythmia (P = 0.0002) or hematuria (P = 0.0001), and were more likely to have a hemoabdomen if they had cardiac dysrhythmia (P = 0.0005). Dogs with hematochezia were more likely to have a septic abdomen (P = 0.0123). Dogs were more likely to receive a transfusion if they had AI (P = 0.033) or hemoabdomen specifically (P = 0.0033). Overall survival to discharge was 89%, which was significantly greater than survival in dogs with pelvic injury that also had septic abdomen (33%; P = 0.0299). IA is common in dogs with pelvic fractures, especially those with sacral fractures. Pelvic fracture characterization had no bearing on the presence of IA. © Veterinary Emergency and Critical Care Society 2016.

    A series of standardized tasks, isometric trunk flexion and extension and maximal Valsalva manoeuvres, were used to evaluate the role of the abdominal musculature in developing an increased intra-abdominal pressure (IAP). Seven male subjects were measured for IAP, myoelectric activity of rectus abdominis (RA), obliquus externus and internus (OE and OI respectively), erector spinae (ES) and isometric trunk torque. IAPs in all experimental conditions were markedly greater than those that occurred while relaxed. In isometric trunk flexion, IAPs were increased with accompanying high levels of activity from the abdominal muscles. In contrast, little activity from the abdominal muscles occurred during isometric trunk extension, although levels of IAP were similar to those found in the isometric flexion condition. With maximal voluntary pressurization (Valsalva manoeuvre) slightly higher levels of IAP than those found in torque conditions were recorded, this pressure being produced with abdominal activities (OE and OI) less than one fourth their recorded maximum. When isometric torque tasks were added to the Valsalva manoeuvre, patterns of muscle activity (RA, OE, OI and ES) were significantly altered. For Valsalva with isometric trunk extension, activity from OE and OI was reduced while IAPs remained fairly constant. These findings indicate that in tasks where an IAP extension moment is warranted, abdominal pressure can be increased without the development of a large counter-moment produced by the dual action of the trunk flexors. Activation of other muscles such as the diaphragm and transversus abdominis is suggested as helping provide control over the level of IAP during controlled trunk tasks.

    Surgical-site infections (SSIs) and intra-abdominal abscesses (IAAs) are the most frequent complications of appendectomy. The role of laparoscopy in the treatment of appendicitis remains controversial concerning the complication rate. The aim of this retrospective cohort study was to compare open and laparoscopic appendectomy for SSI and IAA. All patients undergoing appendectomy between January 1, 2007 and May 31, 2010 were included in the study. Perioperative data and data on postoperative complications were collected from patient files. A questionnaire was used to assess complications after discharge. Main outcome parameters were SSI and IAA. Open appendectomy (OAG) and laparoscopic appendectomy (LAG) were compared with univariate and multivariate analyses for the outcome parameters. Four hundred thirty patients were included in the study. SSI (all: 10.6%, OAG: 11.7%, LAG: 7.5%, P=0.293) and IAA (all: 2.8%, OAG: 2.4%, LAG: 3.8%, P=0.506) were not significantly different between OAG and LAG. Risk factors for SSI were age (P=0.003), body mass index (P=0.017), ASA score (P=0.001), the intraoperative grade of inflammation (P=0.004), and the histologic grade of inflammation (P=0.015). The only risk factor for IAA was the intraoperative grade of inflammation (P=0.028). ASA score (odds ratio: 1.992, P=0.032) and the intraoperative grade of inflammation (odds ratio: 1.573, P=0.006) remained significant in the multivariate analysis for SSI. A higher ASA score correlates with SSI. A higher grade of intraoperative inflammation correlates with SSI and IAA. Laparoscopy has no impact on SSI and IAA in appendectomy.

    The Study for Monitoring Antimicrobial Resistance Trends program monitors the activity of antibiotics against aerobic and facultative Gram-negative bacilli (GNBs) from intra-abdominal infections (IAIs) in patients worldwide. In 2011, 1 929 aerobic and facultative GNBs from 21 hospitals in 16 cities in China were collected. All isolates were tested using a panel of 12 antimicrobial agents, and susceptibility was determined following the Clinical Laboratory Standards Institute guidelines. Among the Gram-negative pathogens causing IAIs, Escherichia coli (47.3%) was the most commonly isolated, followed by Klebsiella pneumoniae (17.2%), Pseudomonas aeruginosa (10.1%), and Acinetobacter baumannii (8.3%). Enterobacteriaceae comprised 78.8% (1521/1929) of the total isolates. Among the antimicrobial agents tested, ertapenem and imipenem were the most active agents against Enterobacteriaceae, with susceptibility rates of 95.1% and 94.4%, followed by amikacin (93.9%) and piperacillin/tazobactam (87.7%). Susceptibility rates of ceftriaxone, cefotaxime, ceftazidime, and cefepime against Enterobacteriaceae were 38.3%, 38.3%, 61.1%, and 50.8%, respectively. The leastactive agent against Enterobacteriaceae was ampicillin/sulbactam (25.9%). The extended-spectrum β-lactamase (ESBL) rates among E. coli, K. pneumoniae, Klebsiella oxytoca, and Proteus mirabilis were 68.8%, 38.1%, 41.2%, and 57.7%, respectively. Enterobacteriaceae were the major pathogens causing IAIs, and the most active agents against the study isolates (including those producing ESBLs) were ertapenem, imipenem, and amikacin. Including the carbapenems, most agents exhibited reduced susceptibility against ESBL-positive and multidrug-resistant isolates.

    To evaluate the effect of increased intra-abdominal pressure (IAP) on the systolic and pulse pressure variations induced by positive pressure ventilation in a porcine model. Experimental study in a research laboratory. Seven mechanically ventilated and instrumented pigs prone to normovolaemia and hypovolaemia by blood withdrawal. Abdominal banding gradually increased IAP in 5-mmHg steps up to 30 mmHg. Variations in systolic pressure, pulse pressure, inferior vena cava flow, and pleural and transmural (LVEDPtm) left-ventricular end-diastolic pressure were recorded at each step. Systolic pressure variations were 6.1+/-3.1%, 8.5+/-3.6% and 16.0+/-5.0% at 0, 10, and 30 mmHg IAP in normovolaemic animals (mean+/-SD; p<0.01 for IAP effect). They were 12.7+/-4.6%, 13.4+/-6.7%, and 23.4+/-6.3% in hypovolaemic animals (p<0.01 vs normovolaemic group) for the same IAP. Fluctuations of the inferior vena cava flow disappeared as the IAP increased. Breath cycle did not induce any variations of LVEDPtm for 0 and 30 mmHg IAP. In this model, the systolic pressure and pulse pressure variations, and inferior vena cava flow fluctuations were dependent on IAP values which caused changes in pleural pressure swing, and this dependency was more marked during hypovolaemia. The present study suggests that dynamic indices are not exclusively related to volaemia in the presence of increased IAP. However, their fluid responsiveness predictive value could not be ascertained as no fluid challenge was performed.

    Emergency department (ED) identification and radiographic evaluation of children with intra-abdominal injuries who need acute intervention can be challenging. To date, it is unclear if a clinical prediction rule is superior to unstructured clinician judgment in identifying these children. The objective of this study was to compare the test characteristics of clinician suspicion with a derived clinical prediction rule to identify children at risk of intra-abdominal injuries undergoing acute intervention following blunt torso trauma. This was a planned subanalysis of a prospective, multicenter observational study of children (trauma conducted in 20 EDs in the Pediatric Emergency Care Applied Research Network (PECARN). Clinicians documented their suspicion for the presence of intra-abdominal injuries needing acute intervention as 50% prior to knowledge of abdominal computed tomography (CT) scanning (if performed). Intra-abdominal injuries undergoing acute intervention were defined by a therapeutic laparotomy, angiographic embolization, blood transfusion for abdominal hemorrhage, or intravenous fluid administration for 2 or more days in those with pancreatic or gastrointestinal injuries. Patients were considered to be positive for clinician suspicion if suspicion was documented as ≥1%. Suspicion ≥ 1% was compared to the presence of any variable in the prediction rule for identifying children with intra-abdominal injuries undergoing acute intervention. Clinicians recorded their suspicion in 11,919 (99%) of 12,044 patients enrolled in the parent study. Intra-abdominal injuries undergoing acute intervention were diagnosed in 203 (2%) patients. Abdominal CT scans were obtained in the ED in 2,302 of the 2,667 (86%, 95% confidence interval [CI] = 85% to 88%) enrolled patients with clinician suspicion ≥1% and in 3,016 of the 9,252 (33%, 95% CI = 32% to 34%) patients with clinician suspicion undergoing acute intervention (197 of 203; 97.0%, 95% CI = 93.7% to 98.9%) was

    Full Text Available Os organofosforados são um grupo de compostos químicos amplamente utilizados em agropecuária como inseticidas, ocasionando intoxicações acidentais em animais e humanos, e mesmo sendo utilizados em tentativas de suicídio. A toxicidade desses produtos decorre sobretudo de insuficiência cárdio-respiratória por compromentimento do sistema nervoso autônomo. Sabe-se que alguns destes compostos induzem em animais de experimentação e em humanos, uma miopatia caracterizada por degeneração de células musculares, comprometendo sobretudo a musculatura respiratória. Baseado no fato de que este comprometimento contribui para a piora da função respiratória, propõe-se um protocolo de avaliação rotineira de miotoxicidade por compostos organofosforados, através de uma bateria mínima e suficiente de colorações e reações histoquímicas para quantificação da necrose muscular. Utilizaram-se como modelo experimental, grupos de ratos albinos (Wistar intoxicados com o organofosforado paraoxon, com e sem antídotos (atropina ou pralidoxima. Verificou-se nos grupos tratados com paraoxon e paraoxon mais atropina, necrose de fibras musculares no diafragma, que atingia em determinadas áreas até 15% das fibras. No grupo tratado com paraoxon mais pralidoxima, a necrose foi mínima, evidenciando o papel mioprotetor deste último antídoto.

    It is common knowledge that an increase of intra-abdomninal pressure (lAP) causes a decrease in the volume of cerebrospinal fluid in the lumbar and lower thoracic region, which may contribute to the development of more high spinal block. There is currently no research devoted to studying the impact of intra-abdominal pressure in pregnancy on the development of high spinal blockade. To investigate effects of intra-abdominal pressure in pregnancy on the development of spinal blockade and incidence of hypotension during cesarean section. 170 pregnant women with gestational age 38-40 weeks were included in the randomized, blinded, controlled study. All the women received elective cesarean section under spinal anesthesia (SA). Pregnant women w|,ere divided into two groups of 85 females each. In the first group, the anesthesiologist did not know the value of lAP and used the dose of local anesthetic focusing on height, weight, and according to his own experience. In the second group, an anesthesiologist corrected dose of local anesthetic depending on the lAP and also considered the height and weight of a woman. In 9.2% of women, lAP was less than 11 mmHg (physiologically normal), in 49%--from 12 to 15 mmHg (degree I of intra-abdominal hypertension (IAH)), in 40.3%--from 16 to 20 mmHg (degree II of IAH), in 1.5%--from 21 to 25 mmHg (degree III of IAH). In the first group, the incidence of high spinal block (above Th4) and incidence of arterial hypotension (systolic blood pressure under 90 mm.Hg) was two times higher than in the second group (phypotension. To prevent these complications, we recommend decreasing the dose of local anesthetic with use of the Scale of the Risk of developing high spinal block in pregnant.

    Full Text Available Abstract Recently, an update of the IDSA guidelines for the treatment of complicated intraabdominal infections has been published. No guideline can cater for all variations in ecology, antimicrobial resistance patterns, patient characteristics and presentation, health care and reimbursement systems in many different countries. In the short time the IDSA guidelines have been available, a number of practical clinical issues have been raised by physicians regarding interpretation of the guidelines. The main debatable issues of the new IDSA guidelines are described as follows: The authors of the IDSA guidelines present recommendations for the following subgroups of "complicated" IAI: community-acquired intra-abdominal infections of mild-to-moderate and high severity and health care-associated intra-abdominal infections (no general treatment recommendations, only information about antimicrobial therapy of specific resistant bacterial isolates. From a clinical point of view, "complicated" IAI are better differentiated into primary, secondary (community-acquired and postoperative and tertiary peritonitis. Those are the clinical presentations of IAI as seen in the emergency room, the general ward and on ICU. Future antibiotic treatment studies of IAI would be more clinically relevant if they included patients in studies for the efficacy and safety of antibiotics for the treatment of the above mentioned forms of IAI, rather than conducting studies based on the vague term "complicated" intra-abdominal infections. The new IDSA guidelines for the treatment of resistant bacteria fail to mention many of new available drugs, although clinical data for the treatment of "complicated IAI" with new substances exist. Further-more, treatment recommendations for cIAI caused by VRE are not included. This group of diseases comprises enough patients (i.e. the entire group of postoperative and tertiary peritonitis, recurrent interventions in bile duct surgery or

    Full Text Available BACKGROUND Fine-Needle Aspiration Cytology (FNAC is a widely used method, which is accurate and safe in a readily palpable masses. But, in those inaccessible lesions and deeper organs are safely aspirated using fine needle radiological procedure like ultrasound or computed tomography guided. The aim of the study is to assess the utility of FNAC in the diagnosis of intra-abdominal lesions and different pattern of lesions in particular to the sites. MATERIALS AND METHODS This retrospective study was done in the Department of Pathology, Regional Institute of Medical Sciences (RIMS, Imphal, between June 2010 and June 2016. The study included 128 intra-abdominal masses. Giemsa and Papanicolaou’s stains were used. The cytological diagnosis was correlated with clinical and radiological data to arrive at a final diagnosis. RESULTS Reports on FNAC smears were retrospectively analysed, which had been done in various anatomic sites- liver (70 cases, colon (19 cases, gallbladder (17 cases, mesenteric lymph nodes (12 cases, ovary (3 cases, adrenals (2 cases and 1 case each of pancreas, peritoneal wall, pelvic, suprapubic and flank masses. The mean age was 42.16 years with M:F of 1.3:1. The diagnostic yield was 85.2% in combination for Ultrasound Guided (USG and Computed Tomography (CT guided aspiration. The smears were classified as benign neoplastic, malignant neoplastic, non-neoplastic, inconclusive and unsatisfactory for interpretation. There were 79 (61.7% malignant neoplastic lesion, 5 (3.9% benign neoplastic lesion, 25 (19.5% non-neoplastic lesion, one (0.7% inconclusive lesions and 18 (14.1% unsatisfactory smears. The liver and the colon were the most common sites. Adenocarcinomas and Hepatocellular Carcinoma (HCC were the most common malignant lesions comprising of 35 (44.3% and 25 (31.6% of the total malignant lesions diagnosed. CONCLUSION Intra-abdominal FNA is a simple, economical and a safe procedure with high sensitivity, specificity and

    It is not clear why some anovulatory women with polycystic ovary syndrome (PCOS) and obesity resume ovulation and others remain anovulatory after weight loss. The objective of this study was to compare the changes in body fat distribution and specifically intra-abdominal fat (IAF) and subcutaneous abdominal fat (SAF) between a group of anovulatory women with PCOS and obesity who resume ovulation (RO+) to those who remain anovulatory (RO-) during a lifestyle program. In a prospective pilot cohort study, anovulatory women with PCOS underwent a 6 month lifestyle program in a tertiary fertility clinic. Body fat distribution was assessed by anthropometrics, dual-energy X-ray absorptiometry (DEXA) and single slice abdominal CT scan at intake, after 3 months and after 6 months. Baseline-corrected changes over time were analysed using generalized estimating equations longitudinal regression analysis. In 32 anovulatory women with PCOS (age, 28 ± 4 years; BMI, 37.5 ± 5.0 kg/m²), there were no significant baseline differences in anthropometrics and biochemical assessment between 14 RO+ participants and 18 RO- participants. RO+ women lost more weight (6.3 versus 3.0%) and abdominal fat on DEXA (15.0 versus 4.3%) compared with RO- women. Resumption of ovulation was associated with early and consistent loss of IAF (12.4 versus 5.0% at 3 months and 18.5 versus 8.6% at 6 months). Loss of SAF between the RO+ women and the RO- women was similar at 3 months (6.2 versus 6.1%) but did not change any further in RO- women (6.1%) as it did in RO+ women (11.4%) at 6 months. In anovulatory women with PCOS and obesity undergoing a lifestyle program, RO+ women lose more body weight and abdominal fat on DEXA than RO- women. In addition, this study shows that early and consistent loss of IAF is associated with resumption of ovulation. Future studies should address the mechanisms behind these changes and should assess interventions aimed at loss of IAF to facilitate resumption of ovulation.

    Recently, the overall incidence of tuberculosis has decreased, but the incidence of an extrapulmonary manifestation in patients with tuberculosis has increased in the Republic of Korea. Although intestinal tuberculosis is not infrequent, a fistula caused by tuberculosis is a rare condition. A 23-year-old man presented with fever, diarrhea and right lower quadrant pain. A computed tomography (CT) scan revealed a lobulated, peripherally enhancing, low density mass in the mesentery. The patient underwent laparoscopic biopsy for necrotic lymph node, and intra-abdominal tuberculous lymphadenitis was diagnosed. Four months after initiating treatment with anti-tuberculous medication, the patient developed fever together with lower abdominal pain. A follow-up CT scan revealed a fistulous tract that had developed between the initially noted lymphadenopathy and the proximal ascending colon. Laparoscopic right hemicolectomy was performed as a curative treatment. This case suggests that a nodo-colonic fistula may occur as a paradoxical response in patients with intra-abdominal tuberculous lymphadenitis during treatment with anti-tuberculous medication.

    Full Text Available Jose A Hidalgo,1,2 Celeste M Vinluan,1–3 Nishaal Antony3 1UTEP/UT Austin Cooperative Pharmacy Program, College of Health Sciences, University of Texas at El Paso, El Paso, 2Department of Pharmacy, College of Pharmacy, The University of Texas at Austin, Austin, 3Department of Internal Medicine, Texas Tech University Health Sciences Center, El Paso, TX, USA Abstract: There has been greater interest in developing additional antimicrobial agents due to the increasing health care costs and resistance resulting from bacterial pathogens to currently available treatment options. Gram-negative organisms including Enterobacteriaceae and Pseudomonas aeruginosa are some of the most concerning threats due to their resistance mechanisms: extended-spectrum beta-lactamase production and Klebsiella pneumoniae carbapenemase enzymes. Ceftazidime is a third-generation broad-spectrum cephalosporin with activity against P. aeruginosa and avibactam is a novel nonbeta-lactam beta-lactamase inhibitor. Avycaz®, the trade name for this new combination antibiotic, restores the activity of ceftazidime against some of the previously resistant pathogens. Avycaz was approved in 2015 for the treatment of complicated urinary tract infections, including pyelonephritis, and complicated intra-abdominal infections with the addition of metronidazole in patients with little to no other treatment options. This review article assesses the clinical trials and data that led to the approval of this antibiotic, in addition to its spectrum of activity and limitations.

    Full Text Available Resumen: La interacción entre variables es una característica inherente de los procesos multivariables, que dificulta su operación y el diseño de sus sistemas de control. Bajo el paradigma de Control por desacoplo se agrupan un conjunto de metodologías, que tradicionalmente han estado orientadas a eliminar o reducir la interacción, y que recientemente algunos investigadores han reorientado con objetivos de solucionar un problema tan complejo como es el control multivariable. Parte del material descrito en este artículo es bien conocido en el campo del control de procesos, pero la mayor parte de él son resultados de varios años de investigación de los autores en los que han primado la generalización del problema, la búsqueda de soluciones de fácil implementación y la combinación de bloques elementales de control PID. Esta conjunción de intereses provoca que no siempre se pueda conseguir un desacoplo perfecto, pero que sí se pueda conseguir una considerable reducción de la interacción en el nivel básico de la pirámide de control, en beneficio de otros sistemas de control que ocupan niveles jerárquicos superiores. El artículo resume todos los aspectos básicos del Control por desacoplo y su aplicación a dos procesos representativos: una planta experimental de cuatro tanques acoplados y un modelo 4×4 de un sistema experimental de calefacción, ventilación y aire acondicionado. Abstract: The interaction between variables is inherent in multivariable processes and this fact may complicate their operation and control system design. Under the paradigm of decoupling control, several methodologies that traditionally have been addressed to cancel or reduce the interactions are gathered. Recently, this approach has been reoriented by several researchers with the aim to solve such a complex problem as the multivariable control. Parts of the material in this work are well known in the process control field; however, most of them are

    Purpose: To validate abdominal ultrasonography and helical computed tomography in detecting causes for sepsis in patients after abdominal surgery and to determine improved criteria for its use. Materials and methods: Eighty-five consecutive surgical patients primarily operated for non-infectious disease were included in this prospective study. Forty-one patients were admitted to the intensive care unit. All patients were suspected of an intra-abdominal sepsis after abdominal surgery. Both ultrasonography (US) and helical abdominal computed tomography (CT) were performed to investigate the origin of an intra-abdominal sepsis. The images of both US and CT were interpreted on a four-point scale by different radiologists or residents in radiology, the investigators were blinded of each other's test. Interpretations of US and CT were compared with a reference standard which was defined by the result of diagnostic aspiration of suspected fluid collections (re)laparotomy, clinical course or the opinion of an independent panel. Likelihood ratios and post-test probabilities were calculated and interobserver agreement was determined using κ statistics. Results: The overall prevalence of an abdominal infection was 0.49. The likelihood ratio (LR) of a positive test-result for US was 1.33 (95% CI: 0.8-2.5) and for CT scan 2.53 (95% CI: 1.4-5.0); corresponding post-test probabilities for US 0.57 (95% CI: 0.42-0.70) and for CT 0.71 (95% CI: 0.57-0.83). The LR of a negative test-result was, respectively, 0.60 (95% CI: 0.3-1.3) and 0.18 (95% CI: 0.06-0.5); corresponding post-test probabilities for US 0.37 (95% CI: 0.20-0.57) and for CT 0.15 (95% CI: 0.06-0.32) were calculated. Conclusion: Computed tomography can be used as the imaging modality of choice in patients suspected of intra-abdominal sepsis after abdominal surgery.

    Full Text Available Background: Intra-abdominal adhesions after surgery are usually in the form of bands and can annoy the patient throughout life causing repeated surgical procedures. Therefore, any action to prevent adhesions after surgery can increase longevity and quality of life. For this aim, this study investigates the effect of streptokinase and normal saline on the 7th day and 1 month after laparotomy. Materials and Methods: Experimental study was conducted on thirty healthy male Wistar rats weighing 200–250 g with age of 3 months divided into three groups of 10. Group I: No treatment, Group II: Received normal saline, and Group III: Received normal saline and streptokinase at the same time. One week and 1 month after laparotomy, the frequency of the presence or absence of adhesion bands was performed by a person who was unaware of the sample grouping. The collected information was analyzed with the SPSS software (version 16; SPSS Inc., Chicago, IL, USA. Results: Adhesion frequency was found to be 20% on the 7th day (early and 1 month after laparotomy (late for Group 1, and it was 40% on early and late for Group II, while 0% on the early and late for Group III. Hence, in the group receiving streptokinase, no early or late adhesion was observed; therefore, it had a significant role in the prevention of intra-abdominal adhesions (P 0.05. Conclusion: According to the results of our study, we believe that streptokinase could be a good antiadhesive agent considering its effectiveness.

    2010-11-01

    Full Text Available Abstract Background Obesity remains a major public health problem, associated with a cluster of metabolic abnormalities. However, individuals exist who are very obese but have normal metabolic parameters. The aim of this study was to determine to what extent differences in metabolic health in very obese women are explained by differences in body fat distribution, insulin resistance and level of physical activity. Methods This was a cross-sectional pilot study of 39 obese women (age: 28-64 yrs, BMI: 31-67 kg/m2 recruited from community settings. Women were defined as 'metabolically normal' on the basis of blood glucose, lipids and blood pressure. Magnetic Resonance Imaging was used to determine body fat distribution. Detailed lifestyle and metabolic profiles of participants were obtained. Results Women with a healthy metabolic profile had lower intra-abdominal fat volume (geometric mean 4.78 l [95% CIs 3.99-5.73] vs 6.96 l [5.82-8.32] and less insulin resistance (HOMA 3.41 [2.62-4.44] vs 6.67 [5.02-8.86] than those with an abnormality. The groups did not differ in abdominal subcutaneous fat volume (19.6 l [16.9-22.7] vs 20.6 [17.6-23.9]. A higher proportion of those with a healthy compared to a less healthy metabolic profile met current physical activity guidelines (70% [95% CIs 55.8-84.2] vs 25% [11.6-38.4]. Intra-abdominal fat, insulin resistance and physical activity make independent contributions to metabolic status in very obese women, but explain only around a third of the variance. Conclusion A sub-group of women exists who are metabolically normal despite being very obese. Differences in fat distribution, insulin resistance, and physical activity level are associated with metabolic differences in these women, but account only partially for these differences. Future work should focus on strategies to identify those obese individuals most at risk of the negative metabolic consequences of obesity and on identifying other factors that

    Work-up for patients presenting to the Emergency Department (ED) following an anterior abdominal stab wound (AASW) has been debated since the 1960s. Experts agree that patients with peritonitis, evisceration, or hemodynamic instability should undergo immediate laparotomy (LAP), however, workup of stable, asymptomatic or non-peritoneal, patients is not clearly defined. To evaluate the accuracy of computed tomography of abdomen and pelvis (CTAP) for diagnosis of intra-abdominal injuries requiring Therapeutic Laparotomy (THER-LAP) in ED patients with AASW. Is a negative CT scan without a period of observation sufficient to safely discharge a hemodynamically stable, asymptomatic AASW patient? We searched PUBMED, EMBASE, and Scopus from their inception until May 2017 for studies on ED patients with AASW. We defined the reference standard test as LAP for patients who were managed surgically and those with THER-LAP were considered as disease-positive. In those who were managed nonsurgically, inpatient observation was considered the reference standard. We used the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2) to evaluate the risk of bias and applicability of the included studies. We attempted to compute the pooled sensitivity, specificity, Likelihood Ratios (LR+, LR-) using a random-effects model with MetaDiSc software and calculate testing and treatment thresholds for CT scan applying the Pauker and Kassirer model. Seven studies were included encompassing 575 patients. The weighted prevalence of THER-LAP was 34.3% (95% CI 30.5-38.2%). Studies had variable quality and the inclusion criteria were not uniform. The operating characteristics of CT scan were: sensitivity 50%-100%, specificity 39%-97%, LR+ 1.0-15.7 and LR- 0.07-1.0. The high heterogeneity (I-square>75%) of the operating characteristics of CT scan prevented pooling of the data and therefore the testing and treatment thresholds could not be estimated. The articles revealed a high prevalence (8

    As space exploration is directed towards destinations beyond low-Earth orbit, the consequent new set of medical risks will drive requirements for new capabilities and more resources to ensure crew health. The Space Medicine Exploration Medical Conditions List (SMEMCL), developed by the Exploration Medical Capability element of the Human Research Program, addresses the risk of "unacceptable health and mission outcomes due to limitations of in-flight medical capabilities". It itemizes 85 evidence-based clinical requirements for eight different mission profiles and identifies conditions warranting further research and technology development. Each condition is given a clinical priority for each mission profile. Four conditions -- intra-abdominal infections, skin lacerations, anaphylaxis, and behavioral emergencies -- were selected as a starting point for analysis. A systematic literature review was performed to understand how these conditions are treated in austere, limited-resource, space-analog environments (i.e., high-altitude and mountain environments, submarines, military deployments, Antarctica, isolated wilderness environments, in-flight environments, and remote, resource-poor, rural environments). These environments serve as analogs to spaceflight because of their shared characteristics (limited medical resources, delay in communication, confined living quarters, difficulty with resupply, variable time to evacuation). Treatment of these four medical conditions in austere environments provides insight into medical equipment and training requirements for exploration-class missions.

    We report 10 cases of pulmonary atelectasis diagnosed by chest computed tomography in patients with neurological or muscular disease. Atelectasis was frequently seen in hypotonic patients who could not roll over on their own. The atelectases located mostly in the dorsal bronchopulmonary segments, adjacent to the heart or diaphragm. Atelectasis diminished in two patients after they became able to roll themselves over. Gravity-related lung compression by the heart and intra-abdominal organs on persistent supine position can cause pulmonary atelectasis in patients with neurological or muscular disease who can not roll over by their own power. To confirm that the prone position reduces compression of the lungs, chest computed tomography was performed in both the supine and the prone position in three patients. Sagittal images with three-dimensional computed tomographic reconstruction revealed significant sternad displacements of the heart and caudal displacements of the dorsal portion of the diaphragm on prone position compared with supine position. The prone position, motor exercises for rolling over, and biphasic cuirass ventilation are effective in reducing gravity-related lung compression. Some patients with intellectual disabilities were also able to cooperate in chest physiotherapy. Chest physiotherapy is useful in preventing atelectasis in patients with neurological or muscular disease. (author)

    We investigated the trend in resistance to carbapenems among isolates of Enterobacteriaceae that had been collected from patients with intra-abdominal infections at five medical centers in Taiwan from 2006 to 2010 and evaluated the correlation between resistance to carbapenems and consumption of said agents as part of the Study for Monitoring Antimicrobial Resistance Trends (SMART). During the study period, the usage of ertapenem and that of total carbapenems (ertapenem, imipenem, and meropenem) increased significantly from 6.13 to 13.38 defined daily doses per 1000 patient-days for ertapenem and from 20.43 to 34.25 defined daily doses per 1000 patient-days for total carbapenems. The most common species were Escherichia coli (n = 1095), Klebsiella spp. (n = 663), and Enterobacter spp. (n = 202). The susceptibility of all isolates to ertapenem and to imipenem varied during the study period. For ertapenem, the rates of nonsusceptibility ranged from 3.5% to 10.3% and those for imipenem ranged from 3.5% to 10.7%. Although the use of carbapenems increased during the study period, there was no marked increase in resistance to carbapenems. Continuous monitoring of resistance trends is necessary so that antimicrobial prescription policies can be adjusted and infection control intervention programs can be implemented.

    Time to source control plays a determinant prognostic role in patients having severe intra-abdominal infections (IAIs). Open abdomen (OA) management became an effective treatment option for peritonitis. Aim of this study was to analyze the correlation between time to source control and outcome in patients presenting with abdominal sepsis and treated by OA. We retrospectively analyzed 111 patients affected by abdominal sepsis and treated with OA from May 2007 to May 2015. Patients were classified according to time interval from first patient evaluation to source control. The end points were intra-hospital mortality and primary fascial closure rate. The in-hospital mortality rate was 21.6% (24/111), and the primary fascial closure rate was 90.9% (101/111). A time to source control ≥6 h resulted significantly associated with a poor prognosis and a lower fascial closure rate (mortality 27.0 vs 9.0%, p = 0.04; primary fascial closure 86 vs 100%, p = 0.02). We observed a direct increase in mortality (and a reduction in closure rate) for each 6-h delay in surgery to source control. Early source control using OA management significantly improves outcome of patients with severe IAIs. This damage control approach well fits to the treatment of time-related conditions, particularly in case of critically ill patients.

    Full Text Available Gram-negative ESKAPE pathogens (Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species are important etiologic agents of nosocomial infection that are frequently resistant to broad-spectrum antimicrobial agents. Gram-negative ESKAPE pathogens were collected from hospitalized patients in 11 Latin American countries from 2013 to 2015 as part of the Study for Monitoring Antimicrobial Resistance Trends (SMART global surveillance program. In total, 2113 isolates from intra-abdominal infections (IAI and 970 isolates from urinary tract infections (UTI were tested against antimicrobial agents using standardized CLSI broth microdilution methodology. Of the agents tested, amikacin demonstrated the highest rates of susceptibility (% for K. pneumoniae (92.2, 92.3, Enterobacter spp. (97.5, 92.1, and P. aeruginosa (85.3, 75.2 isolates from both IAI and UTI, respectively. Ertapenem (68.5, 62.6 and imipenem (79.2, 75.9 showed substantially higher rates of susceptibility (% than other β-lactams, including piperacillin-tazobactam (35.9, 37.4 against ESBL-positive isolates of K. pneumoniae from IAI and UTI, respectively. Rates of susceptibility to all agents tested against A. baumannii were ≤30.9%. Gram-negative ESKAPE pathogens isolated from Latin America demonstrated compromised in vitro susceptibility to commonly prescribed broad-spectrum, parenteral antimicrobial agents. Continued surveillance is warranted. New antimicrobial agents with potent activity against Gram-negative ESKAPE pathogens are urgently needed.

    Today self-expanding polymers are considered as the most promising as means for intracavitary hemostasis in case of continuing bleeding after trauma. Testing of domestic open-cell polyurethane foam composition "Locus" was carried out on the developed experimental model simulating liver trauma of V degree. After damaging 6 experimental rabbits were injected intraperitoneally with 80 ml of the composition. 5 experimental rabbits were included into to control group (haemostatic agent was not given). Estimated blood loss was 111-124 ml. The two-hour survival rate didn't differ significantly: 3 animals survived in the experimental group; 2 animal survived in the control. Despite the 3-4-fold widening of the foam, due to open cells it absorbed 72.6 +/- 8.3 g of blood. Thus, open-cell polyurethane foam intraperitoneal administration of the composition didn't provide a temporary intra-abdominal hemostasis in liver. In order to enhance the hemostatic effect it requires changing the formulation of the polyurethane composition. For a more accurate assessment of the results it is neccessary to perform additional researches on larger animals.

Las miasis (o infestaciones por larvas de moscas cutáneas se encuentran entre este tipo de enfermedades siendo especialmente frecuentes en países tropicales. A propósito de la observación de un caso de miasis cutánea masiva por Cordylobia antropophaga, que ocurrió en una mujer de 34 años de edad al volver de un viaje a Senegal, se ha efectuado una revisión de los casos de miasis cutáneas forunculoides importadas publicados en España, así como de la biología, patología, tratamiento y prevención de la miasis humana por Cordylobia anthropophaga. El caso referido, se caracterizó por la infestación con un número inusualmente elevado de larvas, no sospechándose su etiología hasta la fase final de la enfermedad. La emergencia continuada de larvas (se recogieron 91 generó en la paciente un estado de ansiedad importante. Finalmente, la eliminación de las larvas provocó una rápida mejoría de la paciente. Aunque los casos de miasis cutánea no tienen la gravedad de otras enfermedades importadas, su conocimiento es necesario desde el punto de vista preventivo, diagnóstico y terapeútico. Es importante proceder a la identificación morfológica de las larvas diferenciándolas de otro tipo de miasis con implicaciones terapéuticas diferentes.

    We hypothesized that a longer duration of antibiotic treatment for intra-abdominal infections (IAI) would be associated with an increased risk of extra-abdominal infections (EAI) and high mortality. We reviewed all IAI occurring in a single institution between 1997 and 2010. The IAI were divided into two groups consisting of those with a subsequent EAI and those without; the data for each group were analyzed. Patients with EAI following IAI were matched in a 1:2 ratio with patients who did not develop EAI on the basis of their Acute Physiology and Chronic Health Evaluation (APACHE II) score±1 point. Statistical analyses were done with the Student t-test, χ(2) analysis, Wilcoxon rank sum test, and multi-variable analysis. We identified 2,552 IAI, of which 549 (21.5%) were followed by EAI. Those IAI that were followed by EAI were associated with a longer initial duration of antimicrobial therapy than were IAI without subsequent EAI (median 14 d [inter-quartile range (IQR) 10-22 d], vs. 10 d [IQR 6-15 d], respectively, pEAI following IAI in patients treated initially with antibiotics for 0-7 d was 13.3%, vs. 25.1% in patients treated initially for >7 d (pEAI to 938 patients without subsequent EAI, resulting in a mean APACHE II score of 15.2 for each group. After matching, IAI followed by EAI were associated with a longer duration of initial antimicrobial therapy than were IAI without subsequent EAI (median 14 d [9-22 d], vs. 11 d [7-16 d], respectively, pEAI (pEAI and increased mortality.

    To compare clinical and economic outcomes in patients with community-acquired intra-abdominal infection (IAI) due to extended spectrum beta-lactamase (ESBL) producing (ESBL-positive) bacteria versus non-ESBL-producing (ESBL-negative) bacteria in China. This was a retrospective chart review study of patients hospitalized with community-acquired IAI due to ESBL-positive or ESBL-negative infections caused by Escherichia coli or Klebsiella spp. Data were collected from six hospitals in China that participated in the Study for Monitoring Antibiotic Resistance Trends (SMART) during 2006-2007. Outcomes included clinical response at discharge and following first-line antibiotic, number of antibiotic agents and classes, duration of hospitalization, and overall hospitalization and intravenous antibiotic costs. Of the 85 patients included in the study, 32 (37.6%) had ESBL-positive and 53 (62.4%) had ESBL-negative infections; E. coli was responsible for 77.6% of infections. Infection resolved at discharge in 30 (93.8%) ESBL-positive and 48 (90.6%) ESBL-negative patients (P = NS). Fewer ESBL-positive patients achieved complete response following first-line antibiotics (56.3% versus 83.0%; P = 0.01). ESBL-positive patients required longer antibiotic treatment, more antibiotics, longer hospitalization (24.3 versus 14.6 days; 1.67-fold ratio; P = 0.001), and incurred higher hospitalization costs ( yen24,604 vs. yen13,788; $3604 vs. $2020; 1.78-fold ratio; P < 0.001). Patients with ESBL-positive infection had similar resolution rates at discharge compared to those with ESBL-negative infection, despite poorer first-line antibiotic response. However, ESBL-positive infection led to significantly greater hospitalization cost and intravenous antibiotic cost, and longer hospital stay.

    Muscle size of the hamstring and gluteus maximus (GM) as well as intra-abdominal pressure (IAP) are considered as factors affecting the torque development during hip extension. This study examined the associations of torque development during maximal voluntary isometric hip extension with IAP and muscle size of the hamstring and GM. Anatomical cross-sectional area (ACSA) of the hamstring and thickness of GM were determined in 20 healthy young males using an ultrasonography apparatus (Experiment 1). Torque and IAP were simultaneously measured while subjects performed maximal voluntary isometric hip extension. The IAP was measured using a pressure transducer placed in the rectum and determined at the time at which the developed torque reached to the maximal. In Experiment 2, torque and IAP were measured during maximal voluntary isometric hip flexion in 18 healthy young males. The maximal hip extension torque was significantly correlated with the IAP (r = 0.504, P = 0.024), not with the ACSA of the hamstring (r = 0.307, P = 0.188) or the thickness of GM (r = 0.405, P = 0.076). The relationship was still significant even when the ACSA of the hamstring and the thickness of GM were adjusted statistically (r = 0.486, P = 0.041). The maximal hip flexion torque was not significantly correlated with the IAP (r = -0.118, P = 0.642). The current results suggest that IAP can contribute independently of the muscle size of the agonists to maximal voluntary hip extension torque.

    Full Text Available Inducing beige fat from white adipose tissue (WAT is considered to be a shortcut to weight loss and increasingly becoming a key area in research into treatments for obesity and related diseases. However, currently, animal models of beige fat are restricted to rodents, where subcutaneous adipose tissue (sWAT, benign WAT is more liable to develop into the beige fat under specific activators than the intra-abdominal adipose tissue (aWAT, malignant WAT that is the major source of obesity related diseases in humans.Here we induced beige fat by cold exposure in two species of bats, the great roundleaf bat (Hipposideros armiger and the rickett's big-footed bat (Myotis ricketti, and compared the molecular and morphological changes with those seen in the mouse. Expression of thermogenic genes (Ucp1 and Pgc1a was measured by RT-qPCR and adipocyte morphology examined by HE staining at three adipose locations, sWAT, aWAT and iBAT (interscapular brown adipose tissue.Expression of Ucp1 and Pgc1a was significantly upregulated, by 729 and 23 fold, respectively, in aWAT of the great roundleaf bat after exposure to 10°C for 7 days. Adipocyte diameters of WATs became significantly reduced and the white adipocytes became brown-like in morphology. In mice, similar changes were found in the sWAT, but much lower amounts of changes in aWAT were seen. Interestingly, the rickett's big-footed bat did not show such a tendency in beige fat.The great roundleaf bat is potentially a good animal model for human aWAT browning research. Combined with rodent models, this model should be helpful for finding therapies for reducing harmful aWAT in humans.

    Sepsis is a leading cause of death around the world, and 73-83% of all sepsis cases requiring attention in intensive care units are linked to intra-abdominal infection (IAI) or pneumonia. The activation of innate immunity is central to the manifestation of sepsis, and toll-like receptor (TLR) 4 plays an important role in this activation process. The 299G and 399I alleles of TLR4 have been linked with an increased risk of Gram-negative bacteria (GNB) infections and septic shock in some populations. This case-control study evaluated the prevalence of D299G/T399I polymorphisms in Mexican patients with IAI and/or pneumonia and in healthy controls. Genotyping revealed that 1 in 44 patients (2.3%; CI 95%: 0.05-12.0%) and 4 in 126 controls (3.2%; CI 95%: 0.9-7.9%) were heterozygous for both the D299G and T399l polymorphisms (OR: 0.71, CI 95%: 0.01-7.44, p = NS), confirming the co-segregation of these alleles in this population. Furthermore, the patients with a GNB infection and severe sepsis were not carriers of the risk alleles. In summary, this report shows that the frequency of the D299G and T399I polymorphisms in Mexican-Mestizos is lower than anticipated in comparison with other ethnic groups, emphasizing the variable distribution of TLR4 polymorphisms among different populations. Consequently, this study was not able to detect associations between TLR4 polymorphisms and sepsis in this population. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Objective: To analyze the comparative efficacy of piperacillin-tazobactam (PIP-TAZ and ceftriaxone-sulbactam with adjuvant (CSA in the treatment of intra-abdominal infections (IAIs and to assess the costs associated with respective therapies. Methods: The present study analyzed the data collected from 94 IAI patients treated at a tertiary-care hospital. Patient characteristics, infection types, surgical procedures, antibiotic therapies, treatment durations were recorded and overall cost involved in the infections management was estimated in Indian rupee. Results: In total, 46 patients received PIP-TAZ and 48 patients received CSA. The clinical cure was seen in 39.13% patients of PIP-TAZ group and 62.50% patients of CSA group. The patients diagnosed with mixed culture (Gram-positive and negative infections, needed additional cover of clindamycin to achieve clinical success. The failure patients from PIP-TAZ group were shifted to meropenem therapy. For the patients where meropenem and CSA therapy failed, colistin was given as an additional cover. Comparative cost expenditure analysis of the two drug treatment groups revealed that, the overall treatment cost for patients cured with empirical PIP-TAZ group was 51.79% more than that of CSA therapy. The strongest predictor of the increase in treatment costs was clinical failure. Similar trends were maintained for the patients cured with clindamycin additional therapy and change of therapy, with PIP-TAZ group accounting 36.11% and 39.99% more expenditure than CSA group. Conclusions: This study demonstrates that CSA has comparatively higher efficacy as compared to PIP-TAZ when used along with metronidazole in patients with different types of IAIs. Pharmacoeconomic analysis clearly shows that starting appropriate empirical antibiotic therapy has a large impact on the cost of treatment in management of IAIs and selection of CSA, can significantly reduce the cost involved in the treatment.

O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 4×4 (genótipos de canistel × concentrações de AIB, com quatro repetições e dez estacas por parcela. Foram avaliados a porcentagem de sobrevivência, a retenção foliar, o enraizamento, o calejamento, o número e o comprimento médio de raízes por estaca. O genótipo PC-1 foi superior aos demais, em todas as variáveis avaliadas, com destaque para o enraizamento das estacas, superior a 60%. As concentrações de AIB (0; 1.000; 3.000 e 5.000 mg L-1 não influenciaram na sobrevivência, retenção foliar e enraizamento das estacas, mas aumentaram o número e o comprimento de raízes em relação ao tratamento-controle (sem AIB. Há diferença na capacidade de enraizamento das estacas entre os genótipos de canistel, sendo a melhor resposta obtida com PC-1. A concentração de 3.000 mg L-1 de AIB resulta em maior número e comprimento de raízes nas estacas de canistel.

    Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leucocytes (PBL) after surgery for colorectal cancer. Prospective matched cohort study. Patients undergoing surgery for colorectal cancer were included. Patients who had anastomotic leak or intra-abdominal abscess were included in the infection group (n = 23) and matched with patients without complications for the control group (n = 23). PBL were isolated from postoperative blood samples. Total RNA was extracted and hybridized to the Affymetrix Human Gene 1.0 ST microarray. Patients in the infection group displayed 162 upregulated genes and 146 downregulated genes with respect to the control group. Upregulated genes included examples coding for secreted cytokines involved in tumour growth and invasion (S100P, HGF, MMP8, MMP9, PDGFC, IL1R2). Infection also upregulated some proangiogenic genes (CEP55, TRPS1) and downregulated some inhibitors of angiogenesis (MME, ALOX15, CXCL10). Finally, some inhibitors (HP, ORM1, OLFM4, IRAK3) and activators (GNLY, PRF1, FGFBP2) of antitumour immunity were upregulated and downregulated, respectively, suggesting that the inflammatory environment caused by a postoperative infection favours immune evasion mechanisms of the tumour. Analysis of PBL shows differential expression of certain tumour progression-related genes in colorectal cancer patients who have a postoperative intra-abdominal infection, which in turn may promote the growth of residual cancer cells to become recurrent tumours.

    Full Text Available La mortalidad global por accidente cerebrovascular (ACV ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%.

No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

    The activity of ceftazidime/avibactam and comparator agents was monitored at 73 medical centres across all nine US census bureau regions during 2012. Bacterial isolates were collected from patients hospitalized with pneumonia, urinary tract infections (UTI), intra-abdominal infections (IAI) and bloodstream infections (BSI). The study protocol predetermined the target numbers of strains for each of the requested bacterial species that sites were to collect. Isolates were determined to be clinically relevant at the medical centre and only one isolate per patient episode was collected. There were 1466 Gram-negative isolates from BSI, 3245 from pneumonia patients, 501 from IAI and 2356 from UTI. Ceftazidime/avibactam was active against Enterobacteriaceae from each infection type. The MIC90 values for ceftazidime/avibactam against Enterobacteriaceae isolates from BSI, pneumonia patients, IAI or UTI were 0.25 mg/L. The extended-spectrum cephalosporin resistance rates for Escherichia coli were 8.5% (UTI), 10.4% (IAI), 12.7% (BSI) and 17.5% (pneumonia patients). The extended-spectrum cephalosporin resistance rates for Klebsiella spp. were 13.0% (UTI), 13.9% (BSI), 16.3% (IAI) and 19.3% (pneumonia patients). A total of 96.5% of the Pseudomonas aeruginosa isolates from BSI, 95.8% from pneumonia patients, 96.3% from IAI and 98.7% from UTI exhibited a ceftazidime/avibactam MIC of ≤8 mg/L (CLSI susceptible breakpoint for ceftazidime when tested alone against P. aeruginosa). Most tested agents showed limited activity against Acinetobacter baumannii, except for colistin. A total of 31.2% of A. baumannii displayed ceftazidime/avibactam MIC values of ≤8 mg/L. Ceftazidime/avibactam demonstrated potent broad-spectrum activity against Gram-negative pathogens collected in the USA during 2012 from BSI, pneumonia patients, IAI and UTI. © The Author 2014.

    The objective was to determine the association between the abdominal seat belt sign and intra-abdominal injuries (IAIs) in children presenting to emergency departments with blunt torso trauma after motor vehicle collisions (MVCs). This was a planned subgroup analysis of prospective data from a multicenter cohort study of children with blunt torso trauma after MVCs. Patient history and physical examination findings were documented before abdominal computed tomography (CT) or laparotomy. Seat belt sign was defined as a continuous area of erythema, ecchymosis, or abrasion across the abdomen secondary to a seat belt restraint. The relative risk (RR) of IAI with 95% confidence intervals (CIs) was calculated for children with seat belt signs compared to those without. The risk of IAI in those patients with seat belt sign who were without abdominal pain or tenderness, and with Glasgow Coma Scale (GCS) scores of 14 or 15, was also calculated. A total of 3,740 children with seat belt sign documentation after blunt torso trauma in MVCs were enrolled; 585 (16%) had seat belt signs. Among the 1,864 children undergoing definitive abdominal testing (CT, laparotomy/laparoscopy, or autopsy), IAIs were more common in patients with seat belt signs than those without (19% vs. 12%; RR = 1.6, 95% CI = 1.3 to 2.1). This difference was primarily due to a greater risk of gastrointestinal injuries (hollow viscous or associated mesentery) in those with seat belt signs (11% vs. 1%; RR = 9.4, 95% CI = 5.4 to 16.4). IAI was diagnosed in 11 of 194 patients (5.7%; 95% CI = 2.9% to 9.9%) with seat belt signs who did not have initial complaints of abdominal pain or tenderness and had GCS scores of 14 or 15. Patients with seat belt signs after MVCs are at greater risk of IAI than those without seat belt signs, predominately due to gastrointestinal injuries. Although IAIs are less common in alert patients with seat belt signs who do not have initial complaints of abdominal pain or tenderness, the

    Tigecycline is approved for the treatment of complicated skin and soft-tissue infections (cSSTIs) and complicated intra-abdominal infections (cIAIs) in adults. In this analysis the safety and tolerability profile of tigecycline (used alone or in combination) for the treatment of patients with approved indications of cSSTI and cIAI were examined under real-life clinical conditions. Individual patient-level data were pooled from five European observational studies (July 2006 to October 2011). A total of 254 cSSTI and 785 cIAI patients were included. The mean age was 63 years; 34.4% and 56.6% were in intensive care units, 90.9% and 88.1% had at least one comorbidity and mean Acute Physiology and Chronic Health Evaluation (APACHE) II scores at the beginning of treatment were 15.0 ± 7.9 and 16.9 ± 7.6, respectively. Data on adverse events (AEs) were available for 198 cSSTI and 590 cIAI patients in three studies. Nausea and vomiting were reported in ≤ 2% of patients. The most common serious AEs were multi-organ failure (4.0% and 10.0% in cSSTI and cIAI patients, respectively) and sepsis (4.0% and 6.1%, respectively). Death was recorded for 24/254 (9.4%) cSSTI and 147/785 (18.7%) cIAI patients. Mortality rates were higher in the group with a baseline APACHE II score of >15 compared with those with a score of ≤ 15 (18.7% versus 3.5% for cSSTI patients and 23.8% versus 16.0% for cIAI patients). A similar trend was seen when cIAI patients were stratified by Sequential Organ Failure Assessment (SOFA) score. The safety and tolerability of tigecycline, alone and in combination, are consistent with the level of critical illness among patients in these real-life studies.

    Recently, the emergence of multidrug-resistant organisms such as extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae has raised considerable concern regarding the appropriate treatment of intra-abdominal infections (IAIs). In this study, we investigated the molecular characteristics of ESBL among clinical isolates of Escherichia coli and Klebsiella pneumoniae causing IAIs and their pattern of antimicrobial resistance, which can provide useful information about the epidemiology and risk factors associated with these infections. One hundred sixty-seven E.coli and 47 K. pneumoniae ESBL-producing strains causing IAIs were collected from 9 hospitals in China, during 2012 and 2013. The antimicrobial susceptibility profile of these strains was determined. Polymerase chain reaction and sequencing were performed to identify genes for β-lactamase (blaTEM, blaSHV, blaOXA-1-like, and blaCTX-M). The isolates were also analyzed by pulsed-field gel electrophoresis (PFGE). In 167 ESBL-producing E. coli strains, 104 strains (62.3%) were positive for CTX-M, and 9 strains (5.39%) were positive for SHV. Among the 47 K. pneumoniae strains, 35 strains (74.5%) were positive for SHV-2a, 12 strains (25.5%) were positive for CTX-M. No TEM-type and OXA-1-like strain was detected among all the ESBL-producing strains. Regarding the CTX-M-positive E. coli and K. pneumoniae strains, CTX-M-15 was the most common genotype in E. coli and K. pneumoniae strains, accounting for 28.7% and 17.0%, respectively, followed by CTX-M-55 accounting for 16.2% and 2.13%, respectively; the remaining genotypes included CTX-M-123 and CTX-M-82. PFGE showed that E.coli and K. pneumoniae ESBL-producing strains causing IAIs were diverse and that emerging resistance may not be due to the dissemination of national clones. The present study revealed that in ESBL-producing strains causing IAIs in China, the most common genotype for E.coli was CTX-M-15 and for K. pneumoniae was SHV-2a. However, there was a

    To evaluate in vitro susceptibilities of aerobic and facultative Gram-negative bacterial (GNB) isolates from intra-abdominal infections (IAIs) to 12 selected antimicrobials in Chinese hospitals from 2012 to 2014. Hospital acquired (HA) and community acquired (CA) IAIs were collected from 21 centers in 16 Chinese cities. Extended spectrum beta-lactamase (ESBL) status and antimicrobial susceptibilities were determined at a central laboratory using CLSI broth microdilution and interpretive standards. From all isolated strains the Enterobacteriaceae (81.1%) Escherichia coli accounted for 45.4% and Klebsiella pneumoniae for 20.1%, followed by Enterobacter cloacae (5.2%), Proteus mirabilis (2.1%), Citrobacter freundii (1.8%), Enterobacter aerogenes (1.8%), Klebsiella oxytoca (1.4%), Morganella morganii (1.2%), Serratia marcescens (0.7%), Citrobacter koseri (0.3%), Proteus vulgaris (0.3%) and others (1.0%). Non- Enterobacteriaceae (18.9%) included Pseudomonas aeruginosa (9.8%), Acinetobacter baumannii (6.7%), Stenotrophomonas maltophilia (0.9%), Aeromonas hydrophila (0.4%) and others (1.1%). ESBL-screen positive Escherichia coli isolates (ESBL+) showed a decreasing trend from 67.5% in 2012 to 58.9% in 2014 of all Escherichia coli isolates and the percentage of ESBL+ Klebsiella pneumoniae isolates also decreased from 2012 through 2014 (40.4% to 26.6%), which was due to reduced percentages of ESBL+ isolates in HA IAIs for both bacteria. The overall susceptibilities of all 5160 IAI isolates were 87.53% to amikacin (AMK), 78.12% to piperacillin-tazobactam (TZP) 81.41% to imipenem (IMP) and 73.12% to ertapenem (ETP). The susceptibility of ESBL-screen positive Escherichia coli strains was 96.77%-98.8% to IPM, 91.26%-93.16% to ETP, 89.48%-92.75% to AMK and 84.86%-89.34% to TZP, while ESBL-screen positive Klebsiella pneumoniae strains were 70.56%-80.15% susceptible to ETP, 80.0%-87.5% to IPM, 83.82%-87.06% to AMK and 63.53%-68.38% to TZP within the three year study

    Purpose: To compare three-dimensional conformal proton radiotherapy (3DCPT), intensity-modulated photon radiotherapy (IMRT), and 3D conformal photon radiotherapy (3DCRT) to predict the optimal RT technique for retroperitoneal sarcomas. Methods and Materials: 3DCRT, IMRT, and 3DCPT plans were created for treating eight patients with retroperitoneal or intra-abdominal sarcomas. The clinical target volume (CTV) included the gross tumor plus a 2-cm margin, limited by bone and intact fascial planes. For photon plans, the planning target volume (PTV) included a uniform expansion of 5 mm. For the proton plans, the PTV was nonuniform and beam-specific. The prescription dose was 50.4 Gy/Cobalt gray equivalent CGE. Plans were normalized so that >95% of the CTV received 100% of the dose. Results: The CTV was covered adequately by all techniques. The median conformity index was 0.69 for 3DCPT, 0.75 for IMRT, and 0.51 for 3DCRT. The median inhomogeneity coefficient was 0.062 for 3DCPT, 0.066 for IMRT, and 0.073 for 3DCRT. The bowel median volume receiving 15 Gy (V15) was 16.4% for 3DCPT, 52.2% for IMRT, and 66.1% for 3DCRT. The bowel median V45 was 6.3% for 3DCPT, 4.7% for IMRT, and 15.6% for 3DCRT. The median ipsilateral mean kidney dose was 22.5 CGE for 3DCPT, 34.1 Gy for IMRT, and 37.8 Gy for 3DCRT. The median contralateral mean kidney dose was 0 CGE for 3DCPT, 6.4 Gy for IMRT, and 11 Gy for 3DCRT. The median contralateral kidney V5 was 0% for 3DCPT, 49.9% for IMRT, and 99.7% for 3DCRT. Regardless of technique, the median mean liver dose was <30 Gy, and the median cord V50 was 0%. The median integral dose was 126 J for 3DCPT, 400 J for IMRT, and 432 J for 3DCRT. Conclusions: IMRT and 3DCPT result in plans that are more conformal and homogenous than 3DCRT. Based on Quantitative Analysis of Normal Tissue Effects in Clinic benchmarks, the dosimetric advantage of proton therapy may be less gastrointestinal and genitourinary toxicity.

    Full Text Available Abstract Background Menopause is associated with increased adiposity, especially increased deposition of intra-abdominal (IA adipose tissue (AT. This differs from common or 'dietary' obesity, i.e., obesity apparently due to environmentally stimulated overeating, in which IAAT and subcutaneous (S AT increase in similar proportions. The effect of menopause on adiposity is thought to be due to the decreased secretion of ovarian estrogens. Ovariectomy in rats and other animals is a commonly used model of menopause. It is well known that ovariectomy increases adiposity and that this can be reversed by estradiol treatment, but whether ovariectomy selectively increases IAAT has not been measured directly. Therefore, we used micro-computed tomography (microCT to investigate this question in both chow-fed and dietary-obese rats. Methods Ovariectomized, ovariectomized and estradiol treated, and sham-operated (intact rats were fed chow or chow plus Ensure (Abbott Nutrition; n = 7/group. Total (T AT, IAAT and SAT were measured periodically by microCT. Regional distribution of AT was expressed as IAAT as a percentage of TAT (%IAAT. Excesses in these measures were calculated with respect to chow-fed intact rats to control for normal maturational changes. Chemical analysis of fat was done in chow-fed intact and ovariectomized rats at study end. Data were analyzed by t-tests and planned comparisons. Results Body mass, TAT, total fat mass, fat-free body mass, and %IAAT all increased in chow-fed intact rats during the 41 d study. In chow-fed rats, ovariectomy increased excess body mass, TAT, fat mass, fat-free body mass, and SAT, but had little effect on IAAT, in chow-fed rats, leading to a decrease in %IAAT. Ensure feeding markedly increased SAT, IAAT and TAT and did not significantly affect %IAAT. Ovariectomy had similar effects in Ensure-fed rats as in chow-fed rats, although less statistically reliable. Estradiol treatment prevented all the effects of

    Full Text Available Os organofosforados são um grupo de compostos químicos amplamente utilizados em agropecuária como inseticidas, ocasionando intoxicações acidentais em animais e humanos, e mesmo sendo utilizados em tentativas de suicídio. A toxicidade desses produtos decorre sobretudo de insuficiência cárdio-respiratória por compromentimento do sistema nervoso autônomo. Sabe-se que alguns destes compostos induzem em animais de experimentação e em humanos, uma miopatia caracterizada por degeneração de células musculares, comprometendo sobretudo a musculatura respiratória. Baseado no fato de que este comprometimento contribui para a piora da função respiratória, propõe-se um protocolo de avaliação rotineira de miotoxicidade por compostos organofosforados, através de uma bateria mínima e suficiente de colorações e reações histoquímicas para quantificação da necrose muscular. Utilizaram-se como modelo experimental, grupos de ratos albinos (Wistar intoxicados com o organofosforado paraoxon, com e sem antídotos (atropina ou pralidoxima. Verificou-se nos grupos tratados com paraoxon e paraoxon mais atropina, necrose de fibras musculares no diafragma, que atingia em determinadas áreas até 15% das fibras. No grupo tratado com paraoxon mais pralidoxima, a necrose foi mínima, evidenciando o papel mioprotetor deste último antídoto.Organophosphates comprise a group of chemical compounds extensively used in farming as insecticides, which cause accidental poisoning in animals and men and are also used in suicide attempts. The toxicity of these compounds is due especially to the cardiac and respiratory impairment in consequence of autonomic nervous system disorders. However, it is known that some of these products induce a myopathy in experimental animals and humans. This myopathy is characterized by muscle cell degeneration, involving above all the respiratory muscles. Based on the fact that this involvement certainly enhances the

    Full Text Available La osteomalacia inducida por tumor es una rara enfermedad del metabolismo óseo caracterizada por el aumento en la excreción de fosfato a nivel renal seguido de hipofosfatemia. Es causada por agentes fosfatúricos producidos por determinados tumores. La resección total del tumor resulta en la completa reversión de las anormalidades bioquímicas, la desaparición de las manifestaciones clínicas y los hallazgos en los estudios por imágenes. Presentamos el caso de un varón de 61 años con cuadro clínico y laboratorio compatibles con osteomalacia oncogénica inducida por tumor mesenquimático de localización rinosinusal. En nuestro caso el diagnóstico histológico correspondió a una neoplasia de tipo vascular: hemangiopericitoma.

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

    Full Text Available La obesidad general y en niños es un problema de salud pública con claro aumento a nivel mundial y en Chile. En las edades pediátricas, aparte de sus consecuencias traumatológicas, metabólicas y psicológicas, ya tiene un impacto en el riesgo de enfermedades en las edades adultas. El concepto de síndrome metabólico está en uso hace algunos años en la edad adulta, para aunar factores de riesgo de llegar a desarrollar diabetes tipo II y enfermedad cardiovascular. En pediatría hay suficiente evidencia que son factores predictores de riesgo desde la edad escolar la mayoría de los componentes estudiados en adultos: aumento de circunferencia abdominal, de presión arterial sistólica y diastólica, de triglicéridos y disminución de colesterol HDL sérico. Están en estudio otros componentes del síndrome: resistencia insulínica, adiposidad intraabdominal, hiperuricemia, hiperleptinemia, grosor aumentado de íntimamedia arterial, signos sugerentes de hígado graso. Se justifica el estudio de estos factores en niños y adolescentes obesos y su manejo intensivo por un equipo profesional entrenado.

    Full Text Available El linfoma de Burkitt no endémico es un tumor de frecuente localización abdominal, por lo que se debe tener presente ante cualquier masa intraabdominal. Aunque el tratamiento de elección es la quimioterapia, existe controversia respecto del papel que debe desempeñar la cirugía, especialmente en casos donde el diagnóstico se establece durante una laparotomía exploradora. Este fue el caso de una adolescente de 14 años que presentó una masa hipogástrica y otra menor en la fosa ilíaca derecha. Algunos autores no aceptan la cirugía y añaden que puede retrasar y complicar el tratamiento quimioterápeutico, mientras que otros autores defienden la cirugía reductora de masa tumoral asociada a la quimioterapia. Esta controversia es especialmente importante cuando el diagnóstico se establece en el curso de una laparotomía exploradora, durante la cual hay que decidir si extirpar la masa tumoral o no hacerlo. En nuestro caso decidimos extirpar todo el tumor macroscópico. La buena evolución de nuestra paciente y los resultados comunicados apoyan esta postura.Non-endemic Burkitt's lymphoma is a tumor of frequent abdominal localization that should be taken into consideration before any intraabdominal mass. Although chemotherapy is the election treatment, there is controversy as regards the role surgery should play, specially in those cases where the diagnosis is established by explorative laparotomy. This was the case of a 14-year-old adolescent that presented a hypogastric mass and another lower mass in the right iliac fossa. Some authors do not accept surgery and state that it may delay and complicate chemotherapy, whereas other authors defend the tumoral mass-reducing surgery associated with chemotherapy. This controversy is particularly important when the diagnosis is made in the course of an explorative laparotomy and it should be decided wether to remove the tumoral mass or not.

    Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) have detrimental effects on all organ systems and are associated with increased morbidity and mortality in critically ill patients admitted to an intensive care unit. Intra-bladder measurement of the intra-abdominal pressure (IAP) is currently the gold standard. However, IAH is not always indicative of intestinal ischemia, which is an early and rapidly developing complication. Sensitive biomarkers for intestinal ischemia are needed to be able to intervene before damage becomes irreversible. Gut wall integrity loss, including epithelial cell disruption and tight junctions breakdown, is an early event in intestinal damage. Intestinal Fatty Acid Binding Protein (I-FABP) is excreted in urine and blood specifically from damaged intestinal epithelial cells. Claudin-3 is a specific protein which is excreted in urine following disruption of intercellular tight junctions. This study aims to investigate if I-FABP and Claudin-3 can be used as a diagnostic tool for identifying patients at risk for IAP-related complications. In a multicenter, prospective cohort study 200 adult patients admitted to the intensive care unit with at least two risk factors for IAH as defined by the World Society of the Abdominal Compartment Syndrome (WSACS) will be included. Patients in whom an intra-bladder IAP measurement is contra-indicated or impossible and patients with inflammatory bowel diseases that may affect I-FABP levels will be excluded. The IAP will be measured using an intra-bladder technique. During the subsequent 72 hours, the IAP measurement will be repeated every six hours. At these time points, a urine and serum sample will be collected for measurement of I-FABP and Claudin-3 levels. Clinical outcome of patients during their stay at the intensive care unit will be monitored using the Sequential Organ Failure Assessment (SOFA) score. Successful completion of this trial will provide evidence on the eventual

    The Study for Monitoring Antimicrobial Resistance Trends (SMART) follows trends in resistance among aerobic and facultative anaerobic gram-negative bacilli (GNB) isolated from complicated intra-abdominal infections (cIAIs) in patients around the world. During 2004-2009, three centralized clinical microbiology laboratories serving 59 private hospitals in three large South African cities collected 1,218 GNB from complicated intra-abdominal infections (cIAIs) and tested them for susceptibility to 12 antibiotics according to the 2011 Clinical Laboratory Standards Institute (CLSI) guidelines. Enterobacteriaceae comprised 83.7% of the isolates. Escherichia coli was the species isolated most commonly (46.4%), and 7.6% of these were extended-spectrum β-lactamase (ESBL)-positive. The highest ESBL rate was documented for Klebsiella pneumoniae (41.2%). Overall, ertapenem was the antibiotic most active against susceptible species for which it has breakpoints (94.6%) followed by amikacin (91.9%), piperacillin-tazobactam (89.3%), and imipenem-cilastatin (87.1%), whereas rates of resistance to ceftriaxone, cefotaxime, ciprofloxacin, and levofloxacin were documented to be 29.7%, 28.7%, 22.5%, and 21.1%, respectively. Multi-drug resistance (MDR), defined as resistance to three or more antibiotic classes, was significantly more common in K. pneumoniae (27.9%) than in E. coli (4.9%; p<0.0001) or Proteus mirabilis (4.1%; p<0.05). Applying the new CLSI breakpoints for carbapenems, susceptibility to ertapenem was reduced significantly in ESBL-positive E. coli compared with ESBL-negative isolates (91% vs. 98%; p<0.05), but this did not apply to imipenem-cilastatin (95% vs. 99%; p=0.0928). A large disparity between imipenem-cilastatin and ertapenem susceptibility in P. mirabilis and Morganella morganii was documented (24% vs. 96% and 15% vs. 92%, respectively), as most isolates of these two species had imipenem-cilastatin minimum inhibitory concentrations in the 2-4 mcg/mL range, which

    The aims of this study were to reveal how using the antibiotics recommended by the 2010 Surgical Infection Society (SIS) and Infectious Disease Society of America (IDSA) guidelines can affect the therapeutic outcomes. We reviewed the cases of 53 patients with a postoperative intra-abdominal abscess without anastomotic leakage after gastrointestinal surgery who underwent image-guided percutaneous abscess drainage (PAD) and concomitant antibiotic therapy. The type of antibiotic initially administered was determined based on the surgeon's judgment. A persistent abscess was defined as one or more PAD procedures resulting in complete resolution after 21 or more days. The recommended antibiotics were defined according to 2010 SIS/IDSA guidelines. All 53 patients had complete resolution without the need for surgery. The results of a multivariable analysis revealed that a C-reactive protein level ≥12 mg/dL and non-recommended antibiotics were significant risk factors for a persistent abscess (P = 0.042 and 0.013, respectively). With regard to a fever lasting more than 48 h, there was a significant difference between the recommended (45.1%) and non-recommended (72.7 %) antibiotic groups (P = 0.046). Using the recommended antibiotics may shorten the time to defervescence and reduce the risk of a persistent abscess in patients undergoing PAD for a postoperative abscess after gastrointestinal surgery.

    Full Text Available Background. Research on dairy foods to enhance weight and fat loss when incorporated into a modest weight loss diet has had mixed results. Objective. A 15-week controlled feeding study to determine if dairy foods enhance central fat and weight loss when incorporated in a modest energy restricted diet of overweight and obese adults. Design. A 3-week run-in to establish energy needs; a 12-week 500 kcal/d energy reduction with 71 low-dairy-consuming overweight and obese adults randomly assigned to diets: ≤1 serving dairy/d (low dairy, LD or ≤4 servings dairy/d (adequate dairy, AD. All foods were weighed and provided by the metabolic kitchen. Weight, fat, intra-abdominal adipose tissue (IAAT, subcutaneous adipose tissue (SAT macrophage number, SAT inflammatory gene expression, and circulating cytokines were measured. Results. No diet differences were observed in weight, fat, or IAAT loss; nor SAT mRNA expression of inflammation, circulating cytokines, fasting lipids, glucose, or insulin. There was a significant increase (P=0.02 in serum 25-hydroxyvitamin D in the AD group. Conclusion. Whether increased dairy intake during weight loss results in greater weight and fat loss for individuals with metabolic syndrome deserves investigation. Assessment of appetite, hunger, and satiety with followup on weight regain should be considered.

Dentro de la nueva concepción de la gerencia como suministradora de conocimientos para generar resultados, la competencia de negociación ha venido adquiriendo un gran protagonismo e importancia, esencialmente por constituirse en la herramienta fundamental para la solución de conflictos y para el establecimiento y mantenimiento de relaciones perdurables.

    Full Text Available RESUMEN: En las páginas que siguen se argumenta que al filósofo alemán Gottfried Wilhelm Leibniz —fallecido en Hannover en 1716— o, al menos, a su obra Teodicea, cabría contarlos, echadas las cuentas de la manera que se verá, entre las víctimas del terremoto de Lisboa de 1755. Asimismo se subraya la persistencia del pensamiento de Leibniz en las respuestas dadas por los filósofos del siglo XVIII al trágico suceso. Se estudian las reacciones de Voltaire, de Rousseau y de Kant ante los estragos provocados por el seísmo y se concluye que las manifestaciones de los dos primeros ya habían sido previstas en Teodicea e, incluso, la vía científica pretendida por Kant había sido abierta en Protogaea.ABSTRACT: It is argued here that German philosopher Gottfried Wilhelm Leibniz, passed away in 1716, and, specially, that his work Teodicea, could be considered amongst the victims of the Lisbon earthquake of 1755. The persistence of the Leibniz’s thought in the answers given by the philosophers of the 18th Century to the tragic event is also emphasized. Voltaire and Rousseau’s reactions to the damage caused by the earthquake had been anticipated in Teodicea and the scientific way followed by Kant had been initiated in Protogaea.

MÉTODO: Análise retrospectiva de dados de pacientes atendidos no Serviço de Cirurgia Geral e Aparelho Digestivo do Hospital Universitário Gaffrée-Guinle no período de janeiro de 2001 a dezembro de 2005, a estes se incluiu um caso tratado em outro hospital em época anterior. RESULTADOS: Dentre 4823 pacientes recentemente atendidos, dois apresentaram AE causado por Salmonella enteritidis, enquanto o caso mais antigo o agente responsável foi a Salmonella typhi. Todos eram homens, com idade média de 45 anos. Em nenhum deles foi identificada condição predisponente à formação do abscesso; os exames de imagem foram capazes de diagnosticar o AE. Todos foram tratados por esplenectomia e antibioticoterapia e evoluíram para cura. CONCLUSÕES: A Salmonella, apesar de infrequente, pode ser o agente causal do AE. Caracteristicamente os abscessos eram grandes e apresentavam material necrótico em seu interior. Nesta condição, a esplenectomia associada a antibioticoterapia mostrou-se eficaz no tratamento.

    The type IX secretion system (T9SS) has been recently discovered and is specific to Bacteroidetes species. Porphyromonas gingivalis, a keystone pathogen for periodontitis, utilizes the T9SS to transport many proteins including the gingipain virulence factors across the outer membrane and attach them to the cell surface via a sortase-like mechanism. At least 11 proteins have been identified as components of the T9SS including PorK, PorL, PorM, PorN and PorP, however the precise roles of most of these proteins have not been elucidated and the structural organization of these components is unknown. In this study, we purified PorK and PorN complexes from P. gingivalis and using electron microscopy we have shown that PorN and the PorK lipoprotein interact to form a 50 nm diameter ring-shaped structure containing approximately 32-36 subunits of each protein. The formation of these rings was dependent on both PorK and PorN, but was independent of PorL, PorM and PorP. PorL and PorM were found to form a separate stable complex. PorK and PorN were protected from proteinase K cleavage when present in undisrupted cells, but were rapidly degraded when the cells were lysed, which together with bioinformatic analyses suggests that these proteins are exposed in the periplasm and anchored to the outer membrane via the PorK lipid. Chemical cross-linking and mass spectrometry analyses confirmed the interaction between PorK and PorN and further revealed that they interact with the PG0189 outer membrane protein. Furthermore, we established that PorN was required for the stable expression of PorK, PorL and PorM. Collectively, these results suggest that the ring-shaped PorK/N complex may form part of the secretion channel of the T9SS. This is the first report showing the structural organization of any T9SS component.

    Full Text Available Uma variante da cefaleia crônica diária, a cefaleia por uso excessivo de medicamentos é uma manifestação clínica de frequência ≥ 15 dias por mês, durante 3 meses. Possui um diagnóstico deficiente e um tratamento dividido em etapas, sendo a desintoxicação, a etapa de fundamental importância. Este artigo apresenta uma revisão sobre o tema, contribuindo para o esclarecimento das principais manifestações clínicas, principais teorias envolvendo sua fisiopatologia e a terapêutica farmacológica empregada. A metodologia utilizada foi uma revisão de publicações europeias e americanas, no período de 2001 a 2013, nos idiomas português, inglês e espanhol. Todos os medicamentos utilizados no tratamento sintomático das cefaleias são capazes de cronificar uma cefaleia preexistente, desde que sejam utilizados excessivamente, de forma regular e continuada. A suspensão de tais agentes terapêuticos resultará em melhoria na maioria dos pacientes, porém pode ser necessária a introdução de uma terapia de suporte de transição e/ou terapia profilática. Os tratamentos nao farmacológicos, quando associados ao farmacológico, ampliam a possibilidade de resultados satisfatórios, evitando recaídas.

    Full Text Available La Cystoisospora belli, antes denominada Isospora belli, es el agente etiológico de la cystoisosporiasis, una infección oportunista que afecta a pacientes inmunodeprimidos, caracterizada por diarrea crónica y pérdida ponderal. La incidencia de diarrea crónica por este agente, en pacientes infectados por el VIH, ha disminuido considerablemente. Ello gracias al advenimiento de la terapia antirretroviral de gran actividad (TARGA, con la que se ha logrado mejorar la respuesta inmunológica del paciente y disminuir su carga viral. Se presentan seis casos de cystoisosporiasis recurrente y refractaria en pacientes con infección por VIH, en quienes se diagnosticó cystoisosporiasis pese a que previamente se encontraban recibiendo profilaxis con trimetropin/sulfametoxazol (TMP/SMX. Cinco de ellos evolucionaron de manera tórpida y fallecieron, a pesar de una buena respuesta al TARGA (adecuado incremento de CD4 y disminución de la carga viral hasta rangos indetectables, y de tratamiento con TMP/SMX por vía oral y otros medicamentos de segunda línea.

    Full Text Available São apresentados 31 casos de bacteremia por gram-negativos, assunto que vem merecendo muita atenção dos pesquisadores nos últimos anos. Os organismos etiológicos mais importantes que apareceram em igualdade de freqüência foram Escherichia coli e Klebsiella-Aerobacter, sendo responsáveis por 58% do total das infecções, seguidos por Pseudomonas. A porta de entrada mais freqüente foi o trato urinário em 61,3% dos casos. A infecção foi mais comum no sexo masculino e a faixa etária de 50 a 60 anos predominou. O uso prévio de antibióticos foi um fator predisponente muito importante, seguido pelo uso de esteróides e citostáticos. As principais doenças predisponentes foram diabetes mellitus e neoplasias malignas. Os principais fatores precipitantes foram a manipulação do aparelho urinário, com infecção prévia ou desencadeada, cirurgia do aparelho digestivo, uronatia obstrutiva e obstrução biliar. As principais manifestações clínicas foram a presença de febre, calafrios e hipotensão arterial. A complicação mais freqüente foi o choque bacteriano que incidiu em 58% dos casos, aproximadamente três vêzes aquela relatada na literatura. As outras foram a insuficiência renal aguda, superinfecção e infecção pulmonar metastática. Considerações terapêuticas gerais e esquemas de antibióticos são propostos para estes casos. A mortalidade da bacteremia simples foi de 30,7% e quando associada ao choque elevou-se para 72,2% . As infecções por Pseudomonas foram 100% fatais.

    Full Text Available INTRODUCCIÓN. En los últimos decenios, el sobrepeso y la obesidad han aumentado en los niños y adolescentes cubanos, por lo que son necesarios instrumentos sencillos que permitan analizar en la práctica asistencial las características y evolución de la obesidad. Por esta razón, se decidió desarrollar curvas de crecimiento de la circunferencia de la cintura en niños y adolescentes habaneros, dimensión que muestra una alta correlación con la masa grasa intraabdominal y, por ende, con un perfil lipídico aterogénico. MÉTODOS. Se estimaron valores de percentiles de esta circunferencia según grupos de edad y sexo, utilizando el método de transformación de potencia de tipo Box-Cox (BCPE, en 4 360 niños y adolescentes entre 7,5 y 19,0 años, que integraron las muestras de los estudios transversales de crecimiento y desarrollo efectuados en La Habana durante los años 1998 y 2005. RESULTADOS. La circunferencia de la cintura aumentó de forma significativa con la edad en uno y otro sexo. Los niños mostraron cifras superiores a las de las niñas y los valores que se obtuvieron tienden a ser inferiores a los reportados en otros estudios. CONCLUSIONES. Estas curvas podrían usarse provisionalmente con propósitos clínicos y epidemiológicos hasta que se disponga de referencias de carácter nacional para la identificación de niños escolares y adolescentes con riesgo de desarrollar trastornos relacionados con la adiposidad visceral.

    Full Text Available A partir da constatação de que ainda são incipientes os estudos que buscam investigar a perspectiva cultural do consumo, atrelada à percepção de que pouco se pesquisou sobre o consumo de lazer de consumidores da terceira idade, o artigo tem por objetivo geral apresentar resultados de uma pesquisa empírica cujo objetivo foi investigar como as experiências de consumo nas atividades de lazer por indivíduos da terceira idade interagem com o sistema cultural e simbólico envolvido no fluxo da vida social cotidiana. Para se atingir esses objetivos, adotou-se uma perspectiva interpretativa de investigação, a partir de uma abordagem etnográfica. Os resultados parecem indicar que os processos sociais, desde a construção de relacionamentos entre familiares, amigos e vizinhos até a construção de redes de convivência com integrantes dos clubes de terceira constituem-se os principais processos presentes nas atividades de lazer desses indivíduos.

    O presente artigo pretende fazer uma reflexão, a partir de Gramsci e de Sartre, sobre como as práticas do intelectual e do jornalista, formados em um mesmo locus social, como “técnicos do saber prático”, distanciam-se em virtude dos diferentes compromissos assumidos socialmente. O artigo pretende expor, portanto, alguns dos motivos, a partir da prática do jornalista, que o levam a se afastar da noção de intelectual, embora, muitas vezes, ele reivindique esse status. Argumenta-se sobre como a incorporação da retórica da neutralidade pelos jornalistas, derivada do racionalismo de que a classe burguesa se tornou representante, constituiu um dos braços para a construção dos pressupostos jornalísticos da imparcialidade e da objetividade. Por fim, argumenta-se, a partir das revistas semanais de informação Época, Veja e Istoé, sobretudo nas reportagens de comportamento, sobre como essa retórica instaura uma falsa arena de discussão pluralista nesses semanários sustentada por uma visão naturalizadora das relações humanas, valores, práticas culturais e do próprio ser humano.

    An increase in intra-abdominal fat area (IAFA) is an essential component of metabolic syndrome (MetS). Waist circumference (WC) is not a precise measure of IAFA, and computed tomography (CT) is unsuitable for frequent monitoring. Here, we examined utility of a dual bioelectrical impedance analysis (Dual BIA) for measuring IAFA in obese patients during weight reduction. Fat distribution was measured by Dual BIA and CT in 100 obese outpatients. All fat areas including total, IAFA, and subcutaneous fat by Dual BIA were more closely correlated with those by CT than WC. Estimated IAFA by Dual BIA was significantly correlated with number of MetS components as well as CT, but WC was not. Furthermore, in 61 obese patients who received 6-month weight reduction therapy, estimated IAFA by Dual BIA showed an earlier and greater decrease as well as that by CT than WC and BMI. In addition, decrease in estimated IAFA by Dual BIA through weight reduction had a higher correlation with decrease in IAFA by CT, than WC. This study is the first to demonstrate that the change in estimated IAFA by Dual BIA was highly correlated with that in IAFA by CT during weight reduction therapy. Our findings also indicate that estimated IAFA by Dual BIA is, potentially, a better indicator of severity of MetS, cardiovascular risk factors, and effectiveness of weight reduction than WC, and equal to IAFA by CT. Estimated IAFA by Dual BIA may be useful for monitoring the effectiveness of weight reduction therapy in obese patients.

    Ethnic differences in cardiometabolic risk (CMR) may be related to patterns of ethnic-specific body fat distribution. We aimed to identify differences across ethnic groups in interrelations between BMI, abdominal adiposity, liver fat, and CMR profile. In the International Study of Prediction of Intra-Abdominal Adiposity and Its Relationship With Cardiometabolic Risk/Intra-Abdominal Adiposity, 297 physicians recruited 4504 patients (from 29 countries). In the current cross-sectional analyses, 2011 whites, 166 African Caribbean blacks, 381 Hispanics, 1192 East Asians, and 347 Southeast Asians were included. Computed tomography was used to assess abdominal fat distribution and to estimate liver fat content. Anthropometric variables and CMR profile were measured. Higher ranges of BMI were associated with higher levels of visceral [visceral adipose tissue (VAT)] and deep subcutaneous [deep subcutaneous adipose tissue (DSAT)] adiposity, with significant ethnic differences regarding the slope of these relations. Despite lower absolute BMI values, East Asians presented the largest accumulation of VAT but the lowest accumulation of DSAT with increasing adiposity. The association of BMI with liver fat did not differ between ethnic groups. Liver fat and DSAT were positively correlated with VAT with no ethnic variation. All ethnic groups had a similar association between a 1-SD increase in VAT, DSAT, or liver fat with hypertension, type 2 diabetes, hypertriglyceridemia, low HDL-cholesterol concentration, or high C-reactive protein concentration. Ethnicity significantly affects abdominal adiposity and liver fat partitioning, and East Asians have the most deleterious abdominal fat distribution. Irrespective of ethnicity, abdominal and hepatic fat depots are strongly interrelated and increased with obesity. Higher amounts of VAT or liver fat are associated with a more deteriorated CMR profile in all ethnic groups.

    The objective of this study was to investigate the distribution and susceptibility of aerobic and facultative Gram-negative bacilli (GNB) isolated from patients with intra-abdominal infections (IAIs) in China. From 2002 to 2009, minimum inhibitory concentrations of 14 antibiotics for 3420 aerobic and facultative GNB from up to eight hospitals in six cities were determined by the broth microdilution method. Enterobacteriaceae comprised 82.9% (2834/3420) of the total isolates, with Escherichia coli (49.2%) being the most commonly isolated species followed by Klebsiella pneumoniae (17.0%), Enterobacter cloacae (5.8%) and Citrobacter freundii (2.3%). Amongst the antimicrobial agents tested, the three carbapenems (ertapenem, imipenem and meropenem) were the most active agents against Enterobacteriaceae, with susceptibility rates of 96.1-99.6% (2002-2009), 98.2-100% (2002-2009) and 99.6-100% (2002-2004), respectively, followed by amikacin (86.8-95.1%) and piperacillin/tazobactam (84.5-94.3%). Susceptibility rates of all tested third- and fourth-generation cephalosporins against Enterobacteriaceae declined by nearly 30%, with susceptibility rates of 40.2%, 39.1%, 56.3% and 51.8% in 2009 for ceftriaxone, cefotaxime, ceftazidime and cefepime, respectively. The occurrence of extended-spectrum β-lactamases increased rapidly, especially for E. coli (from 20.8% in 2002 to 64.9% in 2009). Susceptibility of E. coli to ciprofloxacin decreased from 57.6% in 2002 to 24.2% in 2009. The least active agent against Enterobacteriaceae was ampicillin/sulbactam (SAM) (25.3-44.3%). In conclusion, Enterobacteriaceae were the major pathogens causing IAIs, and carbapenems retained the highest susceptibility rates over the 8-year study period. Third- and fourth-generation cephalosporins, fluoroquinolones and SAM may not be ideal choices for empirical therapy of IAIs in China.

Otras causas son infrecuentes. Los quistes del cordón espermático son poco frecuentes, pero aún más su ubicación intraabdominal, su tamaño habitual es insuficiente para producir distensión. El paciente presentado en este caso es un varón con criptorquidia bilateral admitido por distensión abdominal, interpretada inicialmente como síndrome ascítico edematoso. La ecografía interpretó la distensión como ascitis tabicada, y la tomografía computada como debida a un gran quiste. En la exploración quirúrgica se diagnosticó un quiste gigante del cordón espermático de ubicación abdominal.Abdominal distention is a frequent symptom, being often the initial presentation of systemic diseases or gastrointestinal disorders. Other causes are uncommon. Spermatic cord cysts are infrequent, abdominal location is even rarer, and the size of the cysts is usually not enough to produce abdominal distention. In our case a man with bilateral cryptorchidism was admitted with abdominal distention and edema of the lower extremities initially interpreted as ascitic-edematous syndrome. Ultrasonography interpreted abdominal distention as septate ascites, computed tomography as a giant cyst. Exploratory surgery showed a giant spermatic cord cyst in the left spermatic cord.

    Full Text Available The variation in voluntary forage intake is undoubtedly the major dietary factor determining level and efficiency of ruminant production. This variation is bigger and least predictable for grazing ruminants. Range ruminant productivity and efficiency is relatively low due, partly, to intake limitations; productivity could probably be increased most by increasing intake. Distension of the reticulo-rumen wall is the primary intake regulation mechanism of low-quality roughages in range ruminants, digestibility and rate of ingest passage also affect voluntary intake. Body size and metabolic bodysize as well affect intake of grazing animals. Kind and amount of supplementation, forage availability, and grazing intensity have been related to voluntary forage intake. La variación en el consumo voluntario de forraje es indudablemente el principal factor dietario que determina el nivel y eficiencia de producción en un rumiante. Esta variación es mayor y muy difícil de predecir bajo condiciones de pastoreo. La productividad y eficiencia de rumiantes en pastoreo es relativamente baja debido, en parte, a las limitaciones en el consumo; la productividad probablemente se podrá incrementar si se incrementa el consumo. La distensión de la pared del rumenretículo es el principal mecanismo de regulación del consumo de forrajes de baja calidad en rumiantes en pastoreo, aunque la digestibilidad y la tasa de pasaje también afectan el consumo voluntario. Igualmente, el consumo se ve afectado por el tamaño corporal y peso metabólico del animal, por la cantidad y tipo de suplemento ofrecido, por la disponibilidad de forraje y por la intensidad del pastoreo.

Los valores obtenidos fueron comparados con grupos controles. Los resultados mostraron disminución del número de UM; las UM remanentes presentaron amplitud reducida junto a otras cuyo tamaño no superaba el del grupo control, hecho que sugiere la incapacidad de lograr una reinervación adecuada. Las velocidades de conducción motora y sensitiva mostraron valores diminuídos, con mayor compromiso en los segmentos distales. Junto a estos datos se halló respuesta miasteniforme al estímulo repetitivo. Todos estos resultados permiten postular la existencia de un compromiso de la unidad motora, abarcando todos sus segmentos, en pacientes intoxicados con Vincristina.

A discussão teve como cerne os apontamentos de Charles Melman, posto que seja um psicanalista que vem pensando a posição do sujeito nas condições da cultura ocidental atual. Foram destacados aspectos que nos conduziram a elaborar um pensamento em torno de como a neurose histérica aparece no contexto contemporâneo. Partimos do princípio de que sofremos uma mutação cultural, na qual passamos de uma cultura propensa à neurose para uma propensa à perversão. Tal concepção determina que lidamos com sujeitos que funcionam sob a ordem de uma nova economia psíquica e que em decorrência assistimos a expressão de uma histeria coletiva que, por sua vez, seria espaço de reivindicação dos sujeitos, a fim de requisitar um paradeiro e reinventar um pai que já esteja destituído.

A total of 2245 isolates from African and the Middle Eastern (AfME) countries were collected to determine in vitro activity for tigecycline and comparators during 2007-2012 as part of the Tigecycline Evaluation Surveillance Trial program. Tigecycline was launched in the AfME in 2007 and remains active against a wide range of targeted pathogens worldwide. Isolates were recovered from cSSSI (1990) and IAI (255) from 38 sites in 11 AfME countries. Staphylococcus aureus was the most common species from cSSSI (27.9%), and the methicillin-resistant S. aureus rate was 25%. Enterococcus spp. (7.1%) and Streptococcus agalactiae (2.9%) were other common Gram-positive pathogens represented. Enterobacter spp. (14.5%), Pseudomonas aeruginosa (13.9%), Escherichia coli (11.4%), Klebsiella spp. (10.9%), and Acinetobacter spp. (7.2 %) were the most common Gram-negative species collected. Tigecycline MIC(90) values were 0.25 μg/mL against S. aureus. E. coli and Enterobacter spp. had tigecycline MIC(90) values of 1 and 2 μg/mL, respectively. E. coli was the most frequently collected species from IAI (28.3%), followed by Klebsiella spp. (20.8%), Enterococcus spp. (11.8%), and Stenotrophomonas maltophilia (6.3%). Isolates collected from IAI had the following tigecycline MIC(90) values: E. coli (1 μg/mL), Klebsiella spp. and other Enterobacteriaceae (2 μg/mL), Enterococcus spp. (0.25 μg/mL), and S. maltophilia (1 μg/mL). Tigecycline in vitro activity was observed against a broad spectrum of bacterial species, including strains resistant to other antimicrobial classes. Copyright © 2014 Elsevier Inc.

    Full Text Available Se realizó una revisión bibliográfica. La bibliografía correspondiente a los últimos años se consultó con el objetivo de profundizar en el estudio de la nefropatía IgA y se revisaron las características patogénicas y clinicopatogénicas de la enfermedad, así como su abordaje terapéutico. La nefropatía IgA se reconoce como la causa más común de enfermedad glomerular y fueron la hematuria recurrente y la presencia de depósitos de IgA en el mesangio, los signos clínicos y patológicos más característicos de esta enfermedad. La nefropatía IgA no es una afección benigna, su evolución es crónica y progresiva. La proteinuria es un indicador de mal pronóstico y no existe un tratamiento específico eficaz para ella por lo que constituye un reto para el futuro.A literature review was made. Literature issued in the last few years was consulted to go deep into the study of IgA nephropathy and the pathogenic and clinicopathogenic characteristics of the disease and its therapy approach were analyzed. IgA nephropathy is known as the most common cause of glomerular disease, being recurrent hematuria and existence of IgA deposits in the mesangium the most characteristic clinical and pathological signs of the disease. IgA nephropathy is not a bening affection with a chronic and progressive course. Proteinuria is a bad prognosis but there is not any specific efficient treatment for the disease, therefore, this is a challenge for the future.

    Invasive fungal disease is associated to a high mortality rate on critical ill patients. In the last decades an important epidemiological shift has been described. Early diagnosis and treatment are related with a better prognosis. The key factors lie in a set of predictive scores that allow to identify patients that will benefit of early treatment, as well as using diagnosis techniques that are culture independent. New diagnosis approximations are being developed with promising results: in situ hybridisation using PNA-FISH probes, MALDI-TOF MS and rapid nucleic acids detection assays. The use of echinocandin is recommended as antifungal therapy on critical ill patients with candida peritonitis.

Cartagena ha estallado y seguirá estallando en muchos pedazos, convirtiéndose en una ciudad que por su compleja dinámica no alcanza a recomponerse en su organización social ni en sus espacios físicos; por ello se nos muestra como un lugar donde la confrontación con el orden instituido para su funcionamiento es permanente. En ese sentido, puede anotarse que son pocos los que acogen con rigor las normas de tránsito o respetan el espacio público, o practican el cuidado ambiental o respetan el derecho del otro al uso de los recursos institucionales que se ofrecen.

    Full Text Available A toxidez por ferro é o distúrbio nutricional de maior ocorrência em arroz (Oryza sativa L. cultivado em sistemas alagados, derivada da quantidade excessiva de íons ferrosos (Fe2+ gerados pela redução de óxidos de ferro em solos alagados. Em experimento conduzido em casa de vegetação, foram avaliados os efeitos de manejos da água de irrigação na dinâmica de redução de um Planossolo e na manifestação da toxidez por ferro em arroz. Os tratamentos dispostos em blocos completos ao acaso com quatro repetições constaram de cinco manejos da água: T1- início do alagamento no estádio V2-V3 do arroz; T2- início do alagamento no estádio V6-V7; T3- T1 e drenagem no estádio V10-V11; T4- T2 e drenagem no estádio V10-V11; e T5- T1 e drenagens nos estádios V7-V8 e V10-V11. O atraso do início do alagamento para o estádio V6-V7 do arroz manteve os valores do Eh da solução do solo mais elevados, promovendo menor disponibilidade de Fe2+ na solução do solo e deslocando a máxima liberação de Fe2+ na solução do solo para estádios fenológicos mais avançados do arroz. A realização de drenagens ao longo do ciclo vegetativo do arroz promoveu a reoxidação do solo, que ocasionou o aumento dos valores de Eh e redução da concentração de Fe2+ na solução do solo. O uso de drenagens durante o período vegetativo do arroz foi eficiente no controle da toxidez por excesso de ferro, em arroz cultivado em solo alagado.

    Full Text Available Abstract Background The recommendations outlined in the latest guidelines published by the Surgical Infection Society (SIS and the Infectious Disease Society of America (IDSA regarding the proper duration of antibiotic therapy in patients with intra-abdominal infections are limited and non-specific. This ambiguity is due mainly to the lack of clinical trials on the topic of optimal duration of therapy. It is well known that the overuse of antibiotics has several important consequences such as increased treatment costs, reduced clinical efficacy, and above all, the increased emergence of antibiotic-resistant pathogens. Ampicillin-Sulbactam is a commonly used "first line" antibiotic for intra-abdominal infections. Ertapenem and Ampicillin-sulbactam are recommended as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. Methods/Design This study is a prospective multi-center randomized investigation. The study will be performed in the Departments of General, Emergency, and Transplant Surgery of Sant'Orsola-Malpighi University Hospital in Bologna, Italy, in the General Surgery Department of the Ospedali Riuniti of Bergamo, Italy, and in the Trauma and Emergency Surgery Department of Maggiore Hospital in Bologna, Italy, and will be conducted by all surgeons willing to participate in the study. The inclusion period of the study will take approximately two years before the planned number of 142 enrolled patients is reached. Discussion Ertapenem and Ampicillin-sulbactam are recommended both as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. As one of the discussed topic is the optimal duration of the antibiotic therapy and this ambiguity is due mainly to the lack of clinical trials on the topic, the present study aims for obtain precise data.

  13. The PorX Response Regulator of the Porphyromonas gingivalis PorXY Two-Component System Does Not Directly Regulate the Type IX Secretion Genes but Binds the PorL Subunit

    2016-01-01

    The Type IX secretion system (T9SS) is a versatile multi-protein complex restricted to bacteria of the Bacteriodetes phylum and responsible for the secretion or cell surface exposition of diverse proteins that participate to S-layer formation, gliding motility or pathogenesis. The T9SS is poorly characterized but a number of proteins involved in the assembly of the secretion apparatus in the oral pathogen Porphyromonas gingivalis have been identified based on genome substractive analyses. Among these proteins, PorY, and PorX encode typical two-component system (TCS) sensor and CheY-like response regulator respectively. Although the porX and porY genes do not localize at the same genetic locus, it has been proposed that PorXY form a bona fide TCS. Deletion of porX in P. gingivalis causes a slight decrease of the expression of a number of other T9SS genes, including sov, porT, porP, porK, porL, porM, porN, and porY. Here, we show that PorX and the soluble cytoplasmic domain of PorY interact. Using electrophoretic mobility shift, DNA-protein co-purification and heterologous host expression assays, we demonstrate that PorX does not bind T9SS gene promoters and does not directly regulate expression of the T9SS genes. Finally, we show that PorX interacts with the cytoplasmic domain of PorL, a component of the T9SS membrane core complex and propose that the CheY-like PorX protein might be involved in the dynamics of the T9SS.

    Full Text Available Com o intuito de desenvolver um protocolo de enxertia em estacas não enraizadas de figueira 'Roxo de Valinhos' (Ficus carica L., foram realizados dois experimentos com aplicação de duas técnicas de propagação: borbulhia e garfagem. No primeiro experimento, estacas lenhosas de 20 cm de comprimento, coletadas da porção mediana dos ramos, de junho a setembro, foram enxertadas por borbulhia tipo placa e "T" normal. No segundo experimento, os propágulos foram coletados em julho e as estacas foram enxertadas pelo método da garfagem, imergindo-se metade das estacas em solução de 2.000 mg L-1 de AIB por 10 segundos e metade permaneceu como controle. Os enxertos foram protegidos com sacos plásticos transparentes (18 x 3 cm, mantidos por 0, 15, 30, 45 e 60 dias. Posteriormente, as estacas dos dois experimentos foram enterradas a 2/3 de seu comprimento em leito de areia, sob telado (sombrite com 50% de luminosidade. Aos 60 e 120 dias após a enxertia, mensuraram-se a porcentagem de borbulhas e garfos vivos, a porcentagem de borbulhas e garfos brotados, a porcentagem de borbulhas e garfos vivos em porta-enxertos enraizados e o comprimento médio da brotação do enxerto. Concluiu-se que a enxertia da figueira 'Roxo de Valinhos' pode ser efetuada por borbulhia, pelo método "T", e por garfagem, devendo-se efetuar a imersão das estacas em AIB e proteger os garfos por 60 dias.

    Full Text Available Since the publication of White Paper #7 "Phase Scheduling" (Ballard, 2000, work on many projects has been planned with this technique by teams of varying configuration. Many teams have adapted their own approach to developing a "phase schedule", in some cases called a "reverse phase schedule" or a "pull phase schedule". During these planning sessions, ideas have been put in practice that improve on the original scheme and increase the benefits of producing a phase schedule. Perhaps the most significant being the conversations that the teams pursue during the exercise. This paper will briefly describe the authors' current approach to and practices for preparing phase schedules and how this has become, in actuality, phase planning. It will then describe how phase planning produces the project schedule as traditionally understood, and more importantly designs the network of commitments necessary to deliver each project milestone, and how understanding and using the network of commitments improves project performanceDesde la publicación del artículo "Programación por Fases" (Ballard, 2000, el trabajo en muchos proyectos han sido planeado utilizando esta técnica con equipos de configuración variable.

La zona de estudio se ubica en las Parroquias de Pomasqui, San Antonio y Calacalí, donde se han producido riesgos debido a las actividades humanas, en este caso, por la explotación de las canteras para abastecer el mercado de la construcción del Distrito Metropolitano de Quito. La investigación propone determinar los riesgos antrópicos generados por la actividad minera. Los pobladores de la zona identifican que la minería artesanal en sus inicios constituyó una fuente de trabajo, donde sus familias también se involucraban. Actualmente, se observa que en la mayoría de las canteras se utiliza maquinaria especializada y no participan los trabajadores de la zona. Los taludes de las canteras son de 80o y 90o grados, generando amenazas para los trabajadores y moradores de las viviendas aledañas. Uno de los mayores impactos es la contaminación del aire, sin embargo, el suelo y los cursos de agua están siendo afectados por los desperdicios que produce la actividad minera. La población, que está expuesta permanentemente al polvo ocasionado por las canteras y al transporte de material, acusa enfermedades de tipo respiratorio. Así mismo, el ruido ocasionado por el transporte constituye una molestia constante para los pobladores.

  19. La responsabilidad del Estado por la actividad del legislador

    2012-12-01

    Full Text Available Analizar el fenómeno de la responsabilidad del Estado causada por los hechos del legislador ha sido un trabajo desarrollado tanto por la doctrina y la jurisprudencia internacional a mediados del siglo xx. En Francia, por ejemplo, se presentó el primer antecedente jurisprudencial en el año de 1934. En España, su estudio empezó a gestionarse con la promulgación de la Constitución de 1978, presentándose el primer fallo judicial en el año de 1993. Para el caso colombiano, la Constitución de 1991 introdujo en su artículo 90 el fundamento constitucional de la responsabilidad patrimonial del Estado, sin que esto significase que la jurisprudencia del Consejo de Estado encontrase las bases de esta responsabilidad en diferentes disposiciones de la Constitución. Sin embargo, los primeros fallos relacionados con este título de imputación en Colombia fueron emitidos por el máximo tribunal de lo contencioso administrativo en 1998, y por la Corte Constitucional a través de la sentencia C-038 de 2006, providencia judicial que estableció algunas de las características que posee esta figura jurídica.

    Full Text Available Se reporta los dos primeros casos de micetoma pulmonar por Scedosporium sp, en el Perú, tratados quirúrgicamente en el Hospital Nacional Hipólito Unanue. Se practicó resección pulmonar debido a micetoma pulmonar de donde se tomó muestras que fueron enviadas a microbiología y anatomía patológica para cultivo y estudio histopatológico. Se identificó el moho Scedosporium sp en dos pacientes con secuelas cavitarias por tuberculosis, quienes presentaron tos y hemoptisis de dos meses y tres años de evolución, respectivamente. Radiológicamente las cavidades estaban ocupadas por una "bola fúngica". La histopatología indicó presencia de abundantes hifas, indistinguibles de las de Aspergillus sp, mientras que la inmunodifusión para Aspergillus fue negativa.

    Full Text Available En este artículo se trabajan las características de laestructura del comercio exterior en las últimas dosdécadas, presentando la relevancia de las exportaciones no tradicionales. Se comienza por mostrar el soporte teórico del comercio internacional. Luego se presenta cómo el TLC se convierte en la opciónpara volver permanente las preferencias unilaterales de los EEUU, donde son los sectores ya beneficiados por el ATPDEA los que van a mantener sus privilegios, ante el posible rezago de otros sectores sensibles como los intensivos en capital y la agricultura. Por último, se hace hincapié en la necesidad de un modelo de desarrollo industrial acorde con las condiciones estructurales de los territorios en el país.

  2. Conflictos por el territorio en La Boquilla, Cartagena

    2006-01-01

    Full Text Available La Boquilla, es un corregimiento que pertenece al Distrito de Cartagena de Indias, ubicado a dos kilómetros al norte de esta ciudad por la Vía al Mar. Los boquilleros son en su mayoría afrodescendientes, quienes se dedicaban a mediados del siglo XX a la pesca, la agricultura y a la ganadería en pequeña escala. Sin embargo, los procesos de modernización, urbanización y el desarrollo económico de Cartagena, estuvieron acompañados por la expropiación de sus tierras y el debilitamiento de sus prácticas tradicionales de subsistencia, lo que ha menoscabado sus condiciones de vida. Por estos motivos, los proyectos de convertir a La Boquilla en un exclusivo destino turístico internacional, son una amenaza para la supervivencia de su población y de su cultura.

  4. Retinitis por citomegalovirus en un paciente con VIH

    Alena de los Ángeles Vejerano Duany

    Full Text Available La retinitis por citomegalovirus es la infección ocular más frecuente en pacientes con un recuento de linfocitos CD4 inferior a 200 por µL. El aspecto oftalmoscópico de las lesiones se caracteriza, en la mayoría de los casos, por infiltrados retinianos resultados de la necrosis retiniana producida por citomegalovirus y el edema en asociación con hemorragias. Estas lesiones se disponen, por lo general, siguiendo las arcadas vasculares temporales con invasión hacia la mácula. Se presentó una paciente de 24 años de edad, femenina, blanca, ama de casa, con antecedentes patológicos personales oculares sin datos de interés, y antecedentes patológicos personales generales de ser diagnosticadas con VIH. Hace cuatro años que comenzó con tratamiento antirretroviral, y tuvo cambios de tratamiento en dos ocasiones. El último fue impuesto en mayo del año 2011, con el cual presentó mala adherencia terapéutica, y comenzó desde entonces a presentar disminución de su peso corporal de forma marcada en breve período de tiempo. Refiere que desde hace unos meses comenzó a presentar una disminución progresiva de la agudeza visual en el ojo derecho, acompañado de visión borrosa. Adquiere gran importancia este caso, ya que ante la supervivencia de los pacientes con sida, va a ser cada vez más frecuente la aparición de las afecciones oculares relacionadas con esta enfermedad. Dentro de ellas se encuentran las infecciones oportunistas mayores como la retinitis por citomegalovirus.

    Los principales criterios para evaluación y decisión, en la sociedad actual, son inspirados por cálculos económicos. Mucho nos preocupamos de cuentas pero muy poco nos preguntamos de lo que es el dinero. Muy poco reflexionamos filosóficamente, ontológicamente, sobre la naturaleza misma del dinero. ¿Qué es esto que pretende ser la base de nuestra sociedad? El dinero es mentiroso por naturaleza. Es una representación de mucha vida, que no puede ser representada. El dinero es peligroso, se convi...
