    Full Text Available Este estudo tem por objetivo analisar experimentalmente as características macroscópicas e microscópicas de cálculos biliares humanos na cavidade peritoneal de ratos. Foram utilizados 32 ratos Wistar, machos, pesando entre 205 e 268 g. Estes animais foram distribuídos em dois grupos e o procedimento cirúrgico foi realizado em cada grupo: no grupo A (n =16, os animais foram submetidos a manipulação intestinal; no grupo B (n=16, cálculos biliares humanos foram colocados na cavidade peritoneal. Os ratos foram avaliados no 21º e 42º dias do período pós-operatório. Os resultados mostraram que a simples manipulação causou aderências nos animais (n=10. As aderências foram notadas em 11 cálculos no grupo B. Histologicamente não houve fibrose intensa em torno do cálculo, principalmente no 42º dia do período pós-operatório. Não foram observados macro ou micro abscessos e não houve evidências de fluído livre intra-peritoneal. Este estudo demonstra que apesar da baixa incidência de complicações, todas as tentativas devem ser feitas para recuperar cálculos perdidos durante colecistectomia.

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

    Full Text Available Cercariae of Schistosoma mansoni inoculated into the peritoneal cavity of naive mice induced host cell adhesion to their surface, but after 90 minutes the number of adherent cells sharply decreased. The cell detachment is progressive and simultaneous to the cercaria-schistosomule transformation. The histological study showed mainly neutrophils in close contact with the larvae. Mononuclear cells and some eosinophils were occasionally seen surrounding the adherent neutrophils. The scanning electron microscopy showed cells displaying twisted microvilli and several microplicae contacting or spreading over the larval surface, and larvae completely surrounded by clusters of cells. These results suggest that the neutrophils recognize molecules on the cercarial surface which induce their spreadingA inoculação de cercárias de Schistosoma mansoni na cavidade peritoneal de camundongos normais induz uma aderência de células do hospedeiro a essas larvas. Essa adesão decresce rapidamente quando a larva infectante transforma-se em esquistossômulo. O destacamento das células é progressivo e simultâneo à transformação. Os métodos histológicos e a microscopia eletrônica de varredura mostraram que o neutrófilo é a célula predominante em estreito contacto com a larva. Células mononucleadas e eosinófilos foram observados rodeando o parasito, usualmente sem estar em contacto direto com a larva. Os resultados indicam que neutrófilos podem reconhecer, na superfície larvária, moléculas que induzem sua adesão e espalhamento.

    Full Text Available PURPOSE: Tumor markers are substances found in blood and other biological fluids if tumor is present in the body. They can be produced by tumor itself or can be results of cancer - body relation. They may be used in the follow-up of cancer patients to identify tumor recurrence. Pre-treatment levels have prognostic tool and could signalize persistence of minimal residual disease despite radical surgery. METHODS: We operated on 52 patients with upper GI malignancy (32 with gastric cancer and 20 with pancreatic cancer. Blood samples were taken before surgery and peritoneal samples immediately after laparotomy before any manipulation with tumor. All samples were examined by standard biochemical technique and the level was compared with a stage of the disease. RESULTS: Patients suffering from gastric carcinoma of stage I and II had higher level of both markers in sera then in the peritoneal cavity, however most of them were within physiological range. Patients in stage III and IV had average marker levels in the peritoneal cavity higher than in sera. Number of positive findings was increasing according to the stage of the disease. The peritoneal levels of both markers varied extremely in higher stages. In patients suffering from pancreatic carcinoma the CEA levels both in sera and peritoneal cavity were parallel but peritoneal levels were slightly higher in stages III and IV. Ca 19 - 9 was more sensitive for pancreatic cancer. The percentage of positive findings was higher in sera but the level of Ca 19 - 9 was higher in the peritoneal cavity. The number of positive findings again correlated with the stage of the disease. CONCLUSIONS: Levels of tumor markers in sera could signalize inoperability of tumor (Ca 19 - 9 in cases of pancreatic carcinoma; peritoneal levels could predict R1 resection especially in gastric cancer patients and risk of early peritoneal recurrence of the disease. Difference between the levels in the peritoneum and sera may

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

    Full Text Available OBJETIVOS: Estudar os efeitos clínicos da secreção das glândulas salivares labiais na lubrificação das cavidades anoftálmicas secas, avaliar a durabilidade dos resultados e apresentar a técnica do transplante. A aplicação desse procedimento em cavidades anoftálmicas secas é inédita na literatura. MÉTODOS: Estudo prospectivo das cirurgias de enxertos glândulo-mucosos, compostos pela mucosa labial e glândulas salivares subjacentes, colocados no fórnice conjuntival de 5 pacientes com cavidades anoftálmicas que apresentavam grave xeroftalmia e retração dos fórnices conjuntivais. As cirurgias foram realizadas durante o período de julho/00 a janeiro/09. Dois pacientes já haviam sido tratados previamente com enxertos de mucosa ou de pele. A técnica do procedimento é descrita em detalhes. Os parâmetros que serviram para a análise comparativa dos resultados foram o quadro clínico, o aspecto do revestimento da cavidade, o ressecamento da superfície da prótese e a frequência do uso de colírios lubrificantes. RESULTADOS: Em todos os casos foi constatada a integração do enxerto e a melhora dos parâmetros avaliados. A evolução mostrou persistência e estabilidade dos resultados. CONCLUSÕES: A lubrificação da superfície da cavidade produzida pela secreção salivar mostrou ser eficiente, bem tolerada e constante, resultando maior conforto do uso da prótese. Infere-se que essa melhor lubrificação obtida ajuda a prevenir a evolução do processo de retração da cavidade. O transplante das glândulas salivares labiais para o fórnice conjuntival demonstrou ser um procedimento de fácil execução, acessível a qualquer cirurgião oftalmologista.

    Previous imaging reports of peritoneal mesothelioma have described a variety of radiologic appearances, but have not included its pathologic classification. We retrospectively reviewed 10 cases of peritoneal mesothelioma representing the following histologic categories: 7 epithelial, 2 sarcomatoid, and one biphasic. By imaging, epithelial mesotheliomas demonstrated diffuse thickening of the peritoneum and mesentery and/or multiple small nodules. The sarcomatoid-type appeared as a mass and the biphasic-type had radiologic and gross pathologic features of both sarcomatoid and epithelial types. We conclude that peritoneal mesothelioma presents with a wide spectrum of radiographic appearances and should therefore be included in the differential diagnoses of diffuse as well as localized peritoneal processes.

    The definitive diagnosis of peritoneal mesothelioma and its differentiation from metastatic peritoneal carcinomatosis may be difficult because of the clinical, macroscopic, and microscopic variability of the tumor. To this purpose, a combination of criteria, including the clinical picture, the gross pathologic findings, the exclusion of other primary neoplasms, and the microscopic findings, must be taken into consideration. Conventionally, these criteria may be established only after surgical exploration and extensive sampling. Experience with patients with peritoneal mesothelioma and metastatic peritoneal carcinomatosis, as well as a review of the recent imaging literature, shows excellent correlation between computed tomography or ultrasound and the operative or autopsy findings. These imaging modalities showed soft-tissue masses or nodules; thickened omentum (omental cake), peritoneum, mesentery, and bowel wall; pleural plaques; and usually disproportionally small, if any, ascites. The latter two observations may be useful in differentiating mesothelioma from carcinomatosis macroscopically. Furthermore, fine-needle aspiration biopsy, after performing wide sampling of the tumors in different locations under ultrasonic or computed tomographic guidance, produced diagnostic cytologic specimens. Thus, the need for exploratory surgery may be alleviated, and the diagnosis of peritoneal mesothelioma may be made prospectively and relatively noninvasively with the use of computed tomography or ultrasound and fine-needle aspiration biopsy. Since epidemiologic studies predict increasing incidence of this neoplasm, especially among asbestos workers, it is suggested that these techniques be seriously considered as screening methods for high-risk populations.67 references

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

    Full Text Available OBJETIVO: Avaliar o valor prognóstico do lavado peritoneal positivo em pacientes com câncer gástrico sem sinais de disseminação peritoneal ou hematogênica. MÉTODOS: Foram avaliados os pacientes com adenocarcinoma gástrico tratados com operação de intenção curativa. O lavado peritoneal foi classificado como positivo ou negativo para células neoplásicas. Foram obtidos dados demográficos, performance status, histológicos e tipo de operação realizada. Os resultados foram estatisticamente comparados e considerados significantes para valores de p<0,05. RESULTADOS: Foram incluídos 72 portadores de adenocarcinoma gástrico. Durante seguimento médio de 26 meses (um a 39 meses foram observadas 20 recidivas locais ou à distância e 21 mortes. Apenas a presença de metástases linfonodais e a necessidade de ressecção de órgãos adjacentes foram associados à redução significativa da sobrevida livre de recidiva. Houve redução significativa da sobrevida global entre os pacientes com invasão angiolinfática, metástase linfonodal, com necessidade de ressecção de múltiplos órgãos, necessidade de gastrectomia total e maior invasão da parede gástrica. A presença de células tumorais na cavidade peritoneal foi associada a pior sobrevida global, porém sem significância estatística. CONCLUSÃO: Não foi demonstrada associação significativa entre o lavado peritoneal positivo e a sobrevida livre de recidiva ou de sobrevida global entre pacientes com câncer gástrico ressecável.

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

    Full Text Available Peritoneal tuberculosis (TB is an extrapulmonary form of presentation of tuberculosis. HIV infection is a primary risk factor for this condition. Diagnosis requires microbiological or histopathological confirmation in addition to supporting radiological imaging studies. Abdominal ultrasonography and CT are useful to obtain a radiographic diagnosis, with typical findings including diffuse peritoneal thickening, presence of ascites in varying volumes, adenopathies, and caseating nodes. We report 2 cases of patients with ascites and nodular peritoneal thickening on diagnostic images, as well as high CA-125 levels in laboratory tests. In both patients, a diagnosis of peritoneal tuberculosis was reached following a US-guided peritoneal biopsy.

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

    Celso Chuquisana-Mostacero

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

    2005-11-15

    Peritoneal lymphomatosis is a rare manifestation of high grade lymphomas. Although it is difficult to differentiate peritoneal lymphomatosis from other peritoneal diseases such as peritoneal carcinomatosis and leiomyomatosis clinically and radiologically, it should be included in differential diagnosis because the disease is curable with chemotherapy. Consequently, radiologic diagnosis plays a very important role in the detection of this disease. We experienced two cases of peritoneal lymphomatosis with primary gastrointestinal lymphomas in the distal ileum. The two patients were 25 and 50-year-old males. Abdominal CT, ultrasound and barium study were performed on both patients. Both patients had non-Hodgkin's lymphoma confirmed with open or sonographically guided biopsies. Although radiologic appearances overlapped, characteristic findings of long-segmental circumscribed annular mass, aneurysmal luminal dilatation, small to moderate amount of ascites without septation or loculation, diffuse involvement of mesentery, omentum and peritoneum, and enlarged lymph nodes were helpful in narrowing the range of possible diagnoses.

    1992-01-01

    We report an outbreak of fungal peritonitis due to Candida parapsilosis in 12 patients undergoing chronic ambulatory peritoneal dialysis (CAPD). All 12 patients were treated by removal of the CAPD catheter together with systemic antifungal therapy. There were no peritonitis-related deaths. Four patients were successfully returned to CAPD at a later date. Microbiological investigation during the outbreak demonstrated colonization of various areas of the CAPD Unit and medical ward with the organism. C. parapsilosis was also isolated from pigeon guano obtained from window-sills. The number of cases of peritonitis due to this organism decreased markedly after bird-proof netting was installed. We believe that this is the first report of an outbreak of CAPD peritonitis due to faecal carriage of C. parapsilosis by pigeons.

    Peritoneal dialysis (PD) is a kidney replacement therapy for end stage renal disease (ESRD) patients. Despite being a lifesaving treatment, the rate of mortality in patients under PD is elevated, mainly due to the chronic peritoneal dysfunction which is characterized by inflammation, peritoneal fibrosis and neoangiogenesis. The inflammatory process is trigged and modulated by the type of the peritoneal dialysis solutions (PDSs) used during PD. Currently, different PDSs are commercially available: (i) the conventional solutions; (ii) solutions of neutral pH containing low concentration of glucose degradation products (GDPs); (iii) solutions with icodextrin; and (iv) solutions containing taurine. Therefore, the aim of this review is to describe the different types of peritoneal dialysis solutions used during PD and their relationship with systemic and intraperitoneal inflammation. Some studies suggested that solutions of neutral pH containing low concentration of GDPs, icodextrin and taurine have better biocompatibility and lower influence on the inflammatory process compared to the conventional one. On the other hand, the studies, in general, were performed with a small population and for a short period of time. Therefore, further well-designed and -controlled clinical trials with larger number of individuals are required in order to better understand the role of different peritoneal dialysis solution types in the development of inflammation in patients with chronic peritoneal dialysis. Accordingly, studies that are more well-designed, well-controlled and with a larger number of patients are needed to explain and define the role of different types of PDS in the inflammation development in patients with chronic peritoneal dialysis.

    Full Text Available Each year there are over 400 papers published in the field of peritoneal dialysis. In this review I have touched on only a few highlights of some of the more active areas of investigation and development. The advances in controlling peritonitis rates with the Y-set have been dramatic and have resulted in peritonitis rates in many centers less than one episode per 24 patient months. Technique survivals have also improved with lower peritonitis rates. The enormous literature on new approaches to treatment and new understandings of host defenses are beyond the scope of this review. There are also many advances in peritoneal access. We now have many new types of catheters under investigation such as the Swan-Neck Missouri catheter and the Moncrief-Popovich catheter, with complete burial of the catheter until eventual externalization for CAPD training. There have been major advances in understanding the normal healing of exit sites and the early diagnosis and treatment of exit-site infections. All the extensive literature on catheter development in the management of exit sites will be reviewed elsewhere. I have focused primarily on an update of worldwide demographics, some of the new findings in peritoneal transport, the use of low-calcium solutions, experiences with EPO, new thinking about adequacy and nutrition, and finally, on recent comparisons of CAPD and hemodialysis.

    A case of Tsukamurella peritonitis associated with peritoneal dialysis in a 23-year-old woman is described. The organism was difficult to identify and was mistaken for Corynebacterium and atypical mycobacteria. Despite prolonged, multidrug, antimicrobial therapy with conventional antibiotics including vancomycin, ciprofloxacin, rifampin, gentamicin and ceftazidime, catheter removal was required to successfully treat peritonitis. Human infection due to this organism is rare and has been previously reported in only 13 cases, 1 of which was peritonitis. We describe here the second case of Tsukamurella peritonitis associated with peritoneal dialysis.

    Full Text Available Abstract Background Laparoscopy has became as the preferred surgical approach to a number of different diseases because it allows a correct diagnosis and treatment at the same time. In abdominal emergencies, both components of treatment – exploration to identify the causative pathology and performance of an appropriate operation – can often be accomplished via laparoscopy. There is still a debate of peritonitis as a contraindication to this kind of approach. Aim of the present work is to illustrate retrospectively the results of a case-control experience of laparoscopic vs. open surgery for abdominal peritonitis emergencies carried out at our institution. Methods From January 1992 and January 2002 a total of 935 patients (mean age 42.3 ± 17.2 years underwent emergent and/or urgent surgery. Among them, 602 (64.3% were operated on laparoscopically (of whom 112 -18.7% – with peritonitis, according to the presence of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than two previous major abdominal surgeries or massive bowel distension were not treated Laparoscopically. Peritonitis was not considered contraindication to Laparoscopy. Results The conversion rate was 23.2% in patients with peritonitis and was mainly due to the presence of dense intra-abdominal adhesions. Major complications ranged as high as 5.3% with a postoperative mortality of 1.7%. A definitive diagnosis was accomplished in 85.7% (96 pat. of cases, and 90.6% (87 of these patients were treated successfully by Laparoscopy. Conclusion Even if limited by its retrospective feature, the present experience let us to consider the Laparoscopic approach to abdominal peritonitis emergencies a safe and effective as conventional surgery, with a higher diagnostic yield and allows for lesser trauma and a more rapid postoperative recovery. Such features make Laparoscopy a challenging alternative to open surgery in the management algorithm for abdominal

Métodos: foi realizado um estudo prospectivo para a investigação da cavidade uterina com a histerografia, a histerossonografia e a histeroscopia em 18 pacientes. Todas as pacientes apresentavam suspeita de anomalias da cavidade uterina. As principais indicações para a investigação foram: distúrbios do ciclo menstrual, sangramento pós-menopausa e alterações observadas em exames ultra-sonográficos sugestivas de pólipos, miomas e/ou espessamento endometrial. Resultados: a sensibilidade da histerossonografia foi de 90% e a especificidade 87,5%, quando comparadas à histeroscopia. O valor preditivo positivo foi de 90% e o negativo 87,5%. A histerografia, por sua vez, apresentou sensibilidade de 70%, especificidade de 75%, valor preditivo positivo de 77,7% e valor preditivo negativo de 75%. Conclusão: a histerossonografia parece ser um bom método alternativo para a avaliação da cavidade uterina, identificando algumas lesões não observadas à ultra-sonografia convencional ou à histerografia, e permitindo a triagem das pacientes candidatas à realização de uma histeroscopia diagnóstica ou cirúrgica. A histerografia apresentou resultados inferiores à histerossonografia, e não parece ser de utilidade na triagem das pacientes.

    Spontaneous bacterial peritonitis occurs in 30% of patients with ascites due to cirrhosis leading to high morbidity and mortality rates. The pathogenesis of spontaneous bacterial peritonitis is related to altered host defenses observed in end-stage liver disease, overgrowth of microorganisms, and bacterial translocation from the intestinal lumen to mesenteric lymph nodes. Clinical manifestations vary from severe to slight or absent, demanding analysis of the ascitic fluid. The diagnosis is confirmed by a number of neutrophils over 250/mm3 associated or not to bacterial growth in culture of an ascites sample. Enterobacteriae prevail and Escherichia coli has been the most frequent bacterium reported. Mortality rates decreased markedly in the last two decades due to early diagnosis and prompt antibiotic treatment. Third generation intravenous cephalosporins are effective in 70% to 95% of the cases. Recurrence of spontaneous bacterial peritonitis is common and can be prevented by the continuous use of oral norfloxacin. The development of bacterial resistance demands the search for new options in the prophylaxis of spontaneous bacterial peritonitis; probiotics are a promising new approach, but deserve further evaluation. Short-term antibiotic prophylaxis is recommended for patients with cirrhosis and ascites shortly after an acute episode of gastrointestinal bleeding.

    Peritoneal dialysis has a high acceptance rate in Latin America, thus the knowledge concerning complication patterns is of great relevance. This work reviews Latin American data on peritonitis, the most serious complication of peritoneal dialysis. The incidence of peritonitis has been reduced over time, concomitantly with the incorporation of safer exchange systems and the use of prophylactic measurements. Today, rates lower than 1 episode per 24 patient-months are commonly reported. Furthermore, changes in causative organisms have been observed, with predominance of Staphylococcus aureus up through the mid-1990s, as well as increases in coagulase-negative staphylococcus and participation of gram negatives. However, the prevalence of S. aureus is still high, due possibly to climatic conditions and the elevated prevalence of carriers. Resolution rate varies from 55% to 78%, transfer to hemodialysis from 10.9% to 15.4%, and death in 3% to 9.9% of cases. Outcome is worse in S. aureus episodes compared to those with coagulase-negative staphylococcus, despite the higher percentage of oxacillin-resistant strains among the former. In general, despite socioeconomic or climatic conditions, our results are similar to those in developed countries, perhaps as a consequence of technological improvements and/or center expertise.

    The peritoneal mesothelioma is a rare neoplasm which arises from the peritoneal lining of the abdomen, tending to spread along the peritoneal cavity and to invade abdominal organs. Authors report the CT findings of 4 patients with histologically proven peritoneal mesothelioma seen at Dongsan Medical Center, School of Medicine, Keimyung University. None of them had a history of exposure to asbestos and no clear etiologic factor could be determined in any patient. CT showed peritoneal and mesenteric thickenings in all cases, omental thickenings in 3 cases, peritoneal nodules, mesenteric masses or omental masses in 2 cases each other, bowel wall involvement in 1 case, and disproportionally small ascites in 2 cases. Distant hematogenous metastases to the liver and retroperitoneal lymph nodes were seen in 1 case. Our experience with 4 peritoneal mesotheliomas as well as a review of the recent imaging literature shows excellent correlation between computed tomography and the operitoneoscopic findings

    To evaluate the CT findings of peritonitis associated with continuous ambulatory peritoneal dialysis(CAPD). We retrospectively analyzed CT scans of 14 symptomatic patients with peritonitis after CAPD. Diffuse abdominal pain was present in 11, fever in two, and abdominal mass with vomiting in one. The mean duration of CAPD ranged from 10 months to 5 years(mean : 3.9 years). On abdominal CT, we evaluated the presence and location of ascites, bowel wall thickening, cocoon formation, the pattern of enhancement of peritoneal thickening, the presence of calcifications in the peritoneum, and mesenteric and omental change. On enhanced CT, multiloculated ascites was observed in all cases(n=14) ; it was located mainly in the pelvic cavity with small multi-loculated fluid collections in the peritoneal cavity(n=13), including the lesser sac(n=3). In one patient, ascites was located in the space between the greater omentum and anterior peritoneal surface. CT showed ileus in 12 cases, small bowel wall thickening in 11, and cocoon formation in five. Uneven but smooth thickening of the peritoneum, with contrast enhancement, was seen in eight cases, and in five of these, peritoneal thickening was more prominent in the anterior peritoneum. Other findings included reticular opacity in two cases, hematoma of the rectus muscle in one, and umbilical hernia in one. Multiloculated fluid collection, ileus, small bowel wall thickening, uneven but smooth peritoneal thickening, and cocoon formation appear to be CT features of CAPD peritonitis.

    While Mexico has the thirteenth largest economy, a large portion of the population is impoverished. About 90% of the population is Mestizo, the result of the admixture of Mexican Indians and Spaniards, with the Indigenous peoples concentrated in the southeastern region. Treatment for end-stage renal disease (estimated 268 patients per million population) is largely determined by the limited healthcare system and the individual's access to resources such as private insurance ( approximately 15%) and governmental sources ( approximately 85%). With only 5% of the gross national product spent on healthcare and most treatment providers being public health institutions that are often under severe economic restrictions, it is not surprising that many Mexican patients do not receive renal replacement therapy. Mexico uses proportionately more peritoneal dialysis than other countries; 1% of the patients are on automated peritoneal dialysis, 19% on hemodialysis and 80% on CAPD. Malnutrition and diabetes, important risk factors for poor outcome, are prevalent among the patients in CAPD programs.

    Full Text Available Sclerosing encapsulating peritonitis (SEP is a rare chronic inflammatory condition of the peritoneum with an unknown aetiology. Also known as abdominal cocoon, the condition occurs when loops of the bowel are encased within the peritoneal cavity by a membrane, leading to intestinal obstruction. Due to its rarity and nonspecific clinical features, it is often misdiagnosed. The condition presents with recurrent episodes of small bowel obstruction and can be idiopathic or secondary; the latter is associated with predisposing factors such as peritoneal dialysis or abdominal tuberculosis. In the early stages, patients can be managed conservatively; however, surgical intervention is necessary for those with advanced stage intestinal obstruction. A literature review revealed 118 cases of SEP; the mean age of these patients was 39 years and 68.0% were male. The predominant presentation was abdominal pain (72.0%, distension (44.9% or a mass (30.5%. Almost all of the patients underwent surgical excision (99.2% without postoperative complications (88.1%.

    Background Bacterial infections account for most peritoneal dialysis (PD)-associated peritonitis episodes. However, anaerobic PD peritonitis is extremely rare and intuitively associated with intra-abdominal lesions. In this study, we examined the clinical characteristics of PD patients who developed anaerobic peritonitis. Methods We retrospectively identified all anaerobic PD peritonitis episodes from a prospectively collected PD registry at a single center between 1990 and 2010. Only patients receiving more than 3 months of PD were enrolled. We analyzed clinical features as well as outcomes of anaerobic PD peritonitis patients. Results Among 6 patients, 10 episodes of PD-associated peritonitis were caused by anaerobic pathogens (1.59% of all peritonitis episodes during study the period), in which the cultures from 5 episodes had mixed growth. Bacteroides fragilis was the most common species identified (4 isolates). Only 3 episodes were associated with gastrointestinal lesions, and 4 episodes were related to a break in sterility during exchange procedures. All anaerobic pathogens were susceptible to clindamycin and metronidazole, but penicillin resistance was noted in 4 isolates. Ampicillin/sulbactam resistance was found in 2 isolates. In 5 episodes, a primary response was achieved using the first-generation cephalosporin and ceftazidime or aminoglycoside. In 3 episodes, the first-generation cephalosporin was replaced with aminoglycosides. Tenckhoff catheter removal was necessary in 2 episodes. Only one episode ended with mortality (due to a perforated bowel). Conclusion Anaerobic PD-associated peritonitis might be predominantly caused by contamination, rather than intra-abdominal events. Half of anaerobic PD-associated peritonitis episodes had polymicrobial growth. The overall outcome of anaerobic peritonitis is fair, with a high catheter survival rate. PMID:23705895

The disease is transmitted by direct contact with a lesion during the primary or secondary stages, in utero by the transplacental route, or during delivery as the baby passes through an infected canal. The bacterium may infect any organ, causing an infinite number of clinical presentations. Secondary syphilis is characterized by mucocutaneous lesions, a flulike syndrome, and generalized adenopathy. Hepatosplenomegaly may be present. The oral mucosa is the second most frequent site of luetic lesions; the genital areas are the most frequent. In the oral cavity, the most characteristic lesion is a whitish mucosal patch, normally located on the lips, tongue, or palate, which is extremely contagious. The differential diagnosis of this lesion may include oral squamous carcinoma, leukoplakia, candidosis, lichen planus, and hairy oral leukoplakia. Definitive diagnosis is based on clinical information and completed by laboratory examinations even the biopsy can help us. With the diagnosis of secondary syphilis treatment with penicillin G benzathine must be started.

Diversos autores têm descrito a difusão do N2O para cavidades fechadas por métodos como cromatografia gasosa e analisador de gases, que não permitem um estudo macroscópico detalhado do gás. O presente estudo teve como objetivo a filmagem macroscópica no espectro infra-vermelho da difusão de N2O, utilizado em anestesia inalatória, para a cavidade peritoneal de ratos submetidos a pneumoperitônio de 20 mmHg com ar ambiente. MÉTODO: Dividiu-se os animais em três grupos, de acordo com o anestésico utilizado: I - controle venoso: tiopental intra-peritoneal; II - controle inalatório: isoflurano a 1,2% em O2 100%; III - óxido nitroso: N2O 66% em oxigênio e isoflurano a 0,6%. Os termogramas provenientes da descompressão abdominal foram obtidos, por meio de um radiômetro AGEMA 550 filmados a 7 quadros por segundo. RESULTADOS: O N2O demonstrou-se visível ao infra-vermelho. No momento da descompressão abdominal, não houve nos grupos I e II termogramas com rastros de gases visíveis ao infra-vermelho. Houve, porém, rastros de gases visíveis ao infra-vermelho no grupo III.

    The present study was undertaken in order to assess bidirectional peritoneal kinetics of albumin after simultaneous i.v. and i.p. injection of radioiodinated albumin tracers (125I-RISA and 131I-RISA) in eight clinically stable uraemic patients undergoing continuous ambulatory peritoneal dialysis...... (CAPD). The plasma volume, intravascular albumin mass (IVM), and overall extravasation rate of albumin were not significantly different from that found in healthy controls. Albumin flux from the plasma into the peritoneal cavity was 3.71 +/- 0.82 (SD) mumol/h, which was only 3% of the overall...... extravasation rate (137 +/- 52 mumol/h). Albumin flux from the peritoneal cavity into the plasma was substantially lower (0.22 +/- 0.07 mumol/h, P albumin from plasma over 4 h was 14 +/- 3.2 mumol, which was significantly lower than the intraperitoneal albumin...

    Full Text Available Acinetobacter species are assuming an increasingly important role in modern medicine, with their persistent presence in health-care settings and antibiotic resistance. However, clinical reports addressing this issue in patients with peritoneal dialysis (PD peritonitis are rare.All PD peritonitis episodes caused by Acinetobacter that occurred between 1985 and 2012 at a single centre were retrospectively reviewed. Clinical features, microbiological data, and outcomes were analysed, with stratifications based upon temporal periods (before and after 2000.Acinetobacter species were responsible for 26 PD peritonitis episodes (3.5% of all episodes in 25 patients. A. baumannii was the most common pathogen (54%, followed by A. iwoffii (35%, with the former being predominant after 2000. Significantly more episodes resulted from breaks in exchange sterility after 2000, while those from exit site infections decreased (P = 0.01. The interval between the last and current peritonitis episodes lengthened significantly after 2000 (5 vs. 13.6 months; P = 0.05. All the isolates were susceptible to cefepime, fluoroquinolone, and aminoglycosides, with a low ceftazidime resistance rate (16%. Nearly half of the patients (46% required hospitalisation for their Acinetobacter PD-associated peritonitis, and 27% required an antibiotic switch. The overall outcome was fair, with no mortality and a 12% technique failure rate, without obvious interval differences.The temporal change in the microbiology and origin of Acinetobacter PD-associated peritonitis in our cohort suggested an important evolutional trend. Appropriate measures, including technique re-education and sterility maintenance, should be taken to decrease the Acinetobacter peritonitis incidence in PD patients.

    Full Text Available We report a 23-year-old woman with systemic lupus erythematous, lupus nephritis(class IV, and end-stage renal disease on peritoneal dialysis who presented with abdominal pain, nausea, vomiting, and diarrhea for one week. A previous admission for peritonitis occurred one month earlier, and peritoneal fluid culture at that time was negative. She was discharged on three weeks of intraperitoneal cefepime and vancomycin. On the current admission, due to recurrent symptoms approximately two weeks after her antibiotics were discontinued, peritoneal fluid cultures were positive for Mycobacterium fortuitum. The peritoneal catheter was removed, and trimethoprim- sulfamethoxazoleand ciprofloxacin were initially recommended for six months. This was later changed to trimethoprim-sulfamethoxazole and amikacin based on new susceptibilities. M. fortuitum is a rapidly growing mycobacterial species (RGM widely distributedin nature; tap water is the major reservoir. It can produce a wide range of infections inhumans, and outbreaks have been reported in hospitals from contaminated equipment. Immunosuppression and chronic lung disease have been described as predisposing factors for RGM infection. Peritoneal dialysis associated with M. fortuitum infection occurs very rarely; no guidelines exist for treatment recommendations.

    Full Text Available Background. Peritonitis represents a major complication of peritoneal dialysis (PD. The aim of this paper was to systematically collect data on patient-related risk factors for PD-associated peritonitis, to analyze the methodological quality of these studies, and to summarize published evidence on the particular risk factors. Methods. Studies were identified by searches of Pubmed (1990–2012 and assessed for methodological quality by using a modified form of the STROBE criteria. Results. Thirty-five methodologically acceptable studies were identified. The following nonmodifiable risk factors were considered valid and were associated with an increased risk of peritonitis: ethnicity, female gender, chronic lung disease, coronary artery disease, congestive heart failure, cardiovascular disease, hypertension, antihepatitis C virus antibody positivity, diabetes mellitus, lupus nephritis or glomerulonephritis as underlying renal disease, and no residual renal function. We also identified the following modifiable, valid risk factors for peritonitis: malnutrition, overweight, smoking, immunosuppression, no use of oral active vitamin D, psychosocial factors, low socioeconomic status, PD against patient’s choice, and haemodialysis as former modality. Discussion. Modifiable and nonmodifiable risk factors analyzed in this paper might serve as a basis to improve patient care in peritoneal dialysis.

    Fifty patients with peritonitis carcinomatosa were evaluated with computed tomography (CT). CT findings included evidence of mesenteric thickening (60 %), solid mass (20 %), loculated ascites (16 %), ascites (14 %), partly dilated intestine (10 %). Mesenteric thickening showed both intraperitoneal and subperitoneal metastasis. Arrested flow of ascitic fluid (loculated ascites) was one of the most predicting findings of peritonitis carcinomatosa. The seven false negative cases related to small metastatic foci, long distance between autopsy and the last CT examination, or paucity of intraabdominal fat. (author)

    Full Text Available Introducción: Valorar si el descanso peritoneal, de al menos un día semanal, ha supuesto mejoras en la rehabilitación de los pacientes y el impacto clínico que puede suponer. Nos planteamos además cuantificar el beneficio económico. Material y Método: Se realizó un estudio longitudinal, retrospectivo, descriptivo. De los pacientes atendidos en nuestra unidad desde el 1 de enero de 2014 al 31 de diciembre de 2014, se estudiaron los pacientes que cumplieran todo el año de seguimiento y que no procedieran de otras técnicas de depuración como la hemodiálisis o trasplante renal. La muestra de estudio estuvo compuesta por 40 pacientes, de los que 21 tuvieron prescrito al menos 1 día semanal de descanso peritoneal y 19 pacientes sin descanso. Se recogieron las siguientes variables al inicio del periodo de estudio y a los 12 meses: Variables demográficas, variables relacionadas con el estado de volumen, datos clínicos relacionados con la técnica, se pasó una encuesta de satisfacción a todos los pacientes estudiados, y se recogieron los importes del coste mensual de cada tipo de tratamiento. Resultados: Las diferencias iniciales entre los grupos, eran esperables ya que son los valores en los cuales se ha basado la prescripción del día de descanso. La exposición a la glucosa, al comienzo y al final fue menor en el grupo con descanso. Al año, no se encontró diferencias en los parámetros estudiados. Una encuesta de satisfacción nos reveló a que dedican los pacientes el día de descanso y los que no lo tienen a que lo dedicarían. Conclusiones: El descanso peritoneal no ha supuesto una peor evolución de los parámetros clínicos estudiados al año de seguimiento, cumpliendo las recomendaciones de adecuación de diálisis de las guías clínicas. La exposición a la glucosa, aun sin llegar a ser significativa por la duración del estudio, ha sido menor en el grupo con descanso. El día de descanso ha facilitado a los pacientes

    There is a growing demand of dialysis in Asia for end-stage renal failure patients. Diabetes mellitus is the leading cause of end-stage renal failure in many countries in Asia. The growth of peritoneal dialysis (PD) in Asia is significant and seeing a good trend. With the enhanced practices of PD, the quality of care in PD in Asia is also improved. Overall, PD and hemodialysis (HD) are comparable in clinical outcome. There is a global trend in the reduction of peritonitis rates and Asian countries also witness such improvement. The socio-economic benefits of PD for end-stage renal failure patients in both urban and rural areas in the developed and developing regions of Asia are an important consideration. This can help to reduce the financial burden of renal failure in addressing the growing demand of patients on dialysis. Initiatives should be considered to further drive down the cost of PD in Asia. Growing demand for dialysis by an increasing number of end-stage renal failure patients requires the use of a cost-effective quality dialysis modality. PD is found to be comparable to HD in outcome and quality. In most countries in Asia, PD should be more cost-effective than HD. A 'PD-first' or a 'PD as first considered therapy' policy can be an overall strategy in many countries in Asia in managing renal failure patients, taking the examples of Hong Kong and Thailand. (1) PD is cheaper than HD and provides a better quality of life worldwide, but its prevalence is significantly lower than that of HD in all countries, with the exception of Hong Kong. Allowing reimbursement of PD but not HD has permitted to increase the use of PD over HD in many Asian countries like Hong Kong, Vietnam, Taiwan, Thailand, as well as in New Zealand and Australia over the last years. In the Western world, however, HD is still promoted, and the proportion of patients treated with PD decreases. Japan remains an exception in Asia where PD penetration is very low.

    Full Text Available A aplicação intraperitoneal de carboximetilcelulose (CMC tem sido utilizada na prevenção de aderências peritoneais em animais e em humanos. Os objetivos deste trabalho foram avaliar a resposta do peritônio ao trauma cirúrgico e à aplicação de CMC e estudar como se processa a metabolização da CMC. Dezenove eqüinos mestiços foram submetidos à laparotomia, quando se produziram lesões no jejuno distal por abrasão da serosa e isquemia. Nos 9 eqüinos do grupo tratamento, antes da síntese da parede abdominal, foi instilada, na cavidade peritoneal, uma solução estéril de CMC, a 1% na dose de 7ml/kg. Nos eqüinos do grupo controle, nenhum medicamento foi aplicado na cavidade peritoneal. Após a cirurgia, colheram-se sangue e fluido peritoneal em 9 momentos: 4 horas após o fim da cirurgia, nos 3 primeiros dias pós-operatórios, pela manhã e a cada 48 horas nos dias subseqüentes (no 5º, 7º, 9º, 11º e 13º dias pós-operatórios. Os exames laboratoriais demonstraram que todos os animais desenvolveram inflamação peritoneal. Entretanto, nos animais do grupo tratamento, esta inflamação foi mais intensa e com um curso mais longo. Observou-se também que a excreção da CMC ocorreu por fagocitose.Intraperitoneal application of carboxymethylcellulose (CMC has been used for peritoneal adhesions prevention in animals and humans. The objectives of this research was to study the peritoneal response to surgical trauma and application of CMC and also to study how CMC excretion occurs. Nineteen healthy mixed breed horses were submited to laparotomy to produce lesions in distal jejunum by serosal abrasion and ischemia. In the nine horses of the treatment group, 7ml/kg of a 1% CMC sterile solution were instilated in peritoneal cavity before abdominal wall syntesis. No medication was instiled in peritoneal cavitiy of the control group horses. After surgery, blood and peritoneal fluid were colected in 9 postoperative moments: 4 hours after

    Full Text Available Background/Aims: The impact of early peritonitis on the outcome of elderly peritoneal dialysis (PD patients has not been studied. We aimed to research the influence of early peritonitis on patient outcomes in elderly PD patients. Methods: This study involved elderly PD patients (age ≥65 who underwent PD between Jan 1, 2004 and Jul 31, 2013. Patient characteristics were collected in our database. Early peritonitis was defined as peritonitis within 6 months after the initiation of PD. Patient survival and technique were compared among the non-peritonitis, early peritonitis and late peritonitis groups using Cox regression analysis. Results: There were 155 subjects involved in this study. The patients were divided among a non-peritonitis group (n=78, early peritonitis group (n=32 and late peritonitis group (n=45. The organisms causing first peritonitis in the two groups did not differ significantly. After adjustment for age, diabetes, serum albumin and residual renal function, multivariable Cox regression model revealed that compared with the early peritonitis group, both the non-peritonitis group (HR 0.57, RI 0.32-0.99, p=0.046 and the late peritonitis group (HR 0.37, RI 0.16-0.75, p=0.004 exhibited a lower patient mortality rate. Conclusions: Early peritonitis is an independent risk factor for mortality in elderly peritoneal dialysis patients.

    The clinical courses and long-term outcomes of viridans streptococcus (VS) peritoneal dialysis (PD) peritonitis remain unclear. We conducted a retrospective analysis of all PD patients in a single center with gram-positive cocci (GPC) peritonitis between 2005 and 2011, and divided them into 3 groups: VS, other streptococci and other GPC (apart from VS). Clinical characteristics and outcomes of the VS group were compared with the other streptococci and other GPC groups, with prognostic factors determined. A total of 140 patients with 168 episodes of GPC peritonitis (44% of all peritonitis) were identified over 7 years. Among these, 18 patients (13%) developed VS peritonitis, while 14 patients (10%) developed other streptococcal peritonitis. Patients with VS peritonitis had a high cure rate by antibiotic alone (94%), despite a high polymicrobial yield frequency (28%). We found that VS peritonitis carried a lower risk of Tenckhoff catheter removal and relapsing episodes than other GPC peritonitis (6% vs 11%), and a lower mortality than other streptococci peritonitis (0% vs 7%). However, after the index peritonitis episodes, VS, other streptococci, and other GPC group had a significantly increased peritonitis incidence compared with the period before the index peritonitis (all p < 0.01). Patients with VS peritonitis had a significantly higher incidence of refractory peritonitis compared with other streptococci or other GPC peritonitis in the long term (both p < 0.01). VS poses a higher risk of subsequent refractory peritonitis after the index episode as compared with other streptococcal or GPC peritonitis. It might be prudent to monitor the technique of these patients with VS peritonitis closely to avoid further peritonitis episodes. Copyright © 2015 International Society for Peritoneal Dialysis.

    Cavidades reentrantes de nióbio vêm sendo utilizadas pelo grupo Australiano nos transdutores eletromecânicos paramétricos do detector de ondas gravitacionais Niobè. Esses transdutores paramétricos são ativados por um sinal AC na faixa de microondas (banda X), que é modulado pelo sinal mecânico da vibração da antena esférica, com a variação de um parâmetro, que, no caso, é a capacitância da cavidade. Nós estudamos esse tipo de cavidade, com o objetivo de transformá-la de reentrante aberta para reentrante fechada, de forma a utilizá-la nos transdutores paramétricos do detector brasileiro Mario Schenberg. O desempenho do transdutor depende de alguns parâmetros da cavidade, como a sua Figura de Mérito (Q elétrico) e o seu acoplamento elétrico com o circuito externo. Neste trabalho mostramos a medida do Q elétrico como função do acoplamento, do acabamento superficial interno e do vazamento de microondas da cavidade, e mostramos o desempenho esperado para o detector Mario Schenberg usando uma cavidade supercondutora reentrante fechada de nióbio.

  9. History of peritoneal access development.

    Twardowski, Zbylut J

    2006-01-01

    The first peritoneal accesses were devices that had been used in other fields (general surgery, urology, or gynecology): trocars, rubber catheters, and sump drains. In the period after World War II, numerous papers were published with various modifications of peritoneal dialysis. The majority of cases were treated with the continuous flow technique; rubber catheters for inflow and sump drains for outflow were commonly used. At the end of the 1940s, intermittent peritoneal dialysis started to be more frequently used. Severe complications of peritoneal accesses created incentive to design accesses specifically for peritoneal dialysis. The initial three, in the late 1940s, were modified sump drains; however, Ferris and Odel for the first time designed a soft, polyvinyl intraperitoneal tube with metal weights to keep the catheter tip in the pelvic gutter where the conditions for drain are the best. In the 1950s, intermittent peritoneal dialysis was established as the preferred technique; polyethylene and nylon catheters became commercially available and peritoneal dialysis was established as a valuable method for treatment of acute renal failure. The major breakthrough came in the 1960s. First of all, it was discovered that the silicone rubber was less irritating to the peritoneal membrane than other plastics. Then, it was found that polyester velour allowed an excellent tissue ingrowth creating a firm bond with the tissue. When a polyester cuff was glued to the catheter, it restricted catheter movement and created a closed tunnel between the integument and the peritoneal cavity. In 1968, Tenckhoff and Schechter combined these two features and designed a silicone rubber catheter with a polyester cuff for treatment of acute renal failure and two cuffs for treatment of chronic renal failure. This was the most important development in peritoneal access. Technological evolution never ends. Multiple attempts have been made to eliminate remaining complications of the

    Peritoneal dialysis (PD) is an important therapy for patients with end-stage kidney disease and is used in more than 200,000 such patients globally. However, its value is often limited by the development of infections such as peritonitis and exit-site and tunnel infections. Multiple strategies have been developed to reduce the risk of peritonitis including antibiotics, topical disinfectants to the exit site and antifungal agents. However, the effectiveness of these strategies has been variable and are based on a small number of randomised controlled trials (RCTs). The optimal preventive strategies to reduce the occurrence of peritonitis remain unclear.This is an update of a Cochrane review first published in 2004. To evaluate the benefits and harms of antimicrobial strategies used to prevent peritonitis in PD patients. We searched the Cochrane Kidney and Transplant's Specialised Register to 4 October 2016 through contact with the Information Specialist using search terms relevant to this review. Studies contained in the Specialised Register are identified through search strategies specifically designed for CENTRAL, MEDLINE, and EMBASE; handsearching conference proceedings; and searching the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. RCTs or quasi-RCTs in patients receiving chronic PD, which evaluated any antimicrobial agents used systemically or locally to prevent peritonitis or exit-site/tunnel infection were included. Two authors independently assessed risk of bias and extracted data. Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratio (RR) with 95% confidence intervals (CI). Thirty-nine studies, randomising 4435 patients, were included. Twenty additional studies have been included in this update. The risk of bias domains were often unclear or high; risk of bias was judged to be low in 19 (49%) studies for random sequence generation, 12 (31%) studies for

    OBJECTIVE: The purpose of this article is to present the spectrum of radiologic findings of encapsulating peritoneal sclerosis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). CONCLUSION: Although a rare diagnosis, encapsulating peritoneal sclerosis in patients undergoing CAPD has a high morbidity and mortality. Diagnosis is often delayed because clinical features are insidious and nonspecific. Radiologic imaging may be helpful in the early diagnosis of encapsulating peritoneal sclerosis and in facilitating timely intervention for CAPD patients with encapsulating peritoneal sclerosis.

    Peritoneal dialysis (PD) program was established in Farwaniya Hospital Kidney Center, Kuwait, in February 2011. Patient recruitment for this modality of treatment was growing steadily. One of the major complications of PD is peritonitis. There is a belief that PD therapy is inferior and carries more complications than hemodialysis, we aimed to show that PD is a good and a non-inferior option for dialysis therapy with comparable outcome in both patient and technique survival. This was a retrospective analysis of all patients who were on PD from February 2011 to December 2014. Peritonitis rate, exit site infection rate, and all-cause mortality rate were all assessed for this period. Peritonitis rate during the 1 st year, 2011, was 0.92 incidents/year. This number had progressively declined in the following years; in 2012, it was 0.65 incidents/year; in 2013, it was 0.58 incidents/year; and in 2014, it was 0.38 incidents/year. This improvement in the rate of peritonitis incidence could be explained by better education of patients and meticulous supervision of the nursing staff. Farwaniya Hospital Kidney Center had an all-cause mortality rate of 9.3% among patients on renal replacement therapy in 2011. In 2012, all-cause mortality rate increased to 17.1%. The following year, 2013, it decreased to 14.3%, and in 2014, all-cause mortality rate dropped further to 7.6%. All-cause mortality rate among PD patients was zero in 2011. In 2012, the all-cause mortality rate in PD was 11.54%, and in 2013, it decreased to 10.52%. Then, again in 2014, the all-cause mortality rate among PD patients was zero. This improvement in all-cause mortality rate could be explained by the better medical care offered to the end-stage renal disease patients, in particular PD patients, in Farwaniya Hospital Kidney Center.

    Peritonitis is a serious problem in children receiving peritoneal dialysis. Campylobacter jejuni is an unusual cause of peritonitis. A 10-year-old boy who had end stage renal failure due to atypical hemolytic uremic syndrome was admitted to our hospital with abdominal pain and fever. Peritoneal dialysis fluid was cloudy and microscopic examination showed abundant leukocytes. Intraperitoneal cefepime treatment was started. Campylobacter jejuni was isolated from peritoneal dialysis fluid culture and oral clarithromycin was added to the treatment. At the end of therapy, peritoneal fluid culture was negative. To our knowledge, C. jejuni peritonitis was not reported in children previously. Although C. jejuni peritonitis is rarely encountered in children, it should be considered as an etiologic factor for peritonitis. Sociedad Argentina de Pediatría.

    Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

    Peritoneal dialysis (PD) for the treatment of end-stage renal failure was introduced in the 1960s. Nowadays it has evolved to an established therapy that is complementary to hemodialysis (HD), representing 11% of all patients treated worldwide with dialysis. Despite good clinical outcomes and similar results in patient survival between PD and HD, the penetration of PD is decreasing in the Western world. First the major events in the history of the development of PD are described. Then important insights into the physiology of peritoneal transport are discussed and linked to the changes in time observed in biopsies of the peritoneal membrane. Furthermore, the developments in peritoneal access, more biocompatible dialysate solutions, automated PD at home, the establishment of parameters for dialysis adequacy and strategies to prevent infectious complications are mentioned. Finally non-medical issues responsible for the declining penetration in the Western world are analyzed. Only after introduction of the concept of continuous ambulatory PD by Moncrief and Popovich has this treatment evolved in time to a renal replacement therapy. Of all structures present in the peritoneal membrane, the capillary endothelium offers the rate-limiting hindrance for solute and water transport for the diffusive and convective transport of solutes and osmosis. The functional and anatomical changes in the peritoneal membrane in time can be monitored by the peritoneal equilibrium test. Peritonitis incidence decreased by introduction of the Y-set and prophylaxis using mupirocin on the exit site. The decrease in the proportion of patients treated with PD in the Western world can be explained by non-medical issues such as inadequate predialysis patient education, physician experience and training, ease of HD initiation, overcapacity of in-center HD, lack of adequate infrastructure for PD treatment, costs and reimbursement issues of the treatment.

    Full Text Available Pore formation is an important concern in laser welding of automotive aluminum alloys. This paper investigates the influence of the laser beam defocusing on pore formation during continuous wave Nd: YAG laser welding of aluminum automotive alloys 5182 and 5754. It was found that the instability of the keyhole during welding was a dominant cause of pore formation while hydrogen rejection played an insignificant role. The defocusing of the laser beam greatly affected the stability of the keyhole. Finally, the mechanism of the collapse of the keyhole and pore formation is proposed.

    Full Text Available Peritoneal dialysis (PD is a well-established modality for treatment of patients with end-stage renal disease, giving excellent patient and technique survival rates. In Saudi Arabia, data collected by the Saudi Center for Organ Transplantation showed that in 2008, patients on PD accounted for a mere 4.8% of total patients on renal replacement therapy, including hemodialysis and renal transplantation. This study was conducted to identify the characteristics of membrane per-meability in the Saudi population and to assess the role of various factors affecting solute transport across the peritoneal membrane. We followed up a total of 52 patients on Continuous Ambulatory Peritoneal Dialysis (CAPD as well as Automated Peritoneal Dialysis (APD, being treated in the PD unit of the King Khalid University Hospital, Riyadh. There were 30 female and 22 male patients; 14 patients were using CAPD while 38 patients were on APD. The mean age of the patients was 50.5 years, with a range of 14-86 years. The average body mass index (BMI was 27.1 kg/m 2 and the mean body surface area (BSA of the study patients was 1.71 m 2 . A standardized PET test was performed on all patients, 4-6 weeks after initiation of regular PD. The Kt/V and creatinine clearance measured 6-8 weeks after initiation of dialysis were 1.96 and 56.59 L/week, respectively. Residual renal function was assessed on the basis of daily urine output, using 24-hour urine collection. The mean serum urea con-centration was 16.91 mmol/L and mean serum creatinine was 702 μmol/L. According to the Peritoneal Equiliberation Test (PET, 8% of the subjects belonged to the high trans-porter category, 44% patients belonged to the high-average transport group, 46% to the low-average category and 2% came in the low transporter category. Our study suggests that the patient characteristics and demographic para-meters seen in the Saudi population are comparable to those seen in other studies from the Middle East and

    Full Text Available Visceral and peritoneal anomalies are frequently encountered during cadaveric dissections and surgical procedures of abdomen. A thorough knowledge of the same is required for the success of diagnostic, surgical and radiological procedures of abdomen. We report multiple peritoneal and visceral anomalies noted during dissection classes for medical undergraduates. The anomalies were found in an adult male cadaver aged approximately 70 years. The right iliac fossa was empty due to the sub-hepatic position of caecum and appendix. The sigmoid colon formed an inverted “U” shaped loop above the sacral promontory in the median position. It entered the pelvis from the right side and descended along the lateral wall of the pelvis. The sigmoid mesocolon was attached obliquely to the posterior abdominal wall, just above the sacral promontory. Further there was a cysto-colic fold of peritoneum extending from the right colic flexure. We discuss the clinical significance of the variations.

De los neurilemomas extracraneales, aproximadamente un 25 a un 45% ocurren en cabeza y cuello. La edad de afectación predominante es entre la tercera y la cuarta décadas de vida. El neurilemoma es un tumor claramente circunscrito y, generalmente, de pequeño tamaño. Clínicamente aparece como una masa de crecimiento lento y gradual. El examen microscópico es necesario para el diagnóstico. El tratamiento de elección es la escisión quirúrgica completa tumoral y después de ésta es muy rara su recurrencia. El propósito de este artículo es presentar un estudio retrospectivo, de nueve casos, de neurilemomas de cavidad oral y cuello, tratados en nuestro servicio de Cirugía Oral y Maxilofacial, entre 1997 y 2001.

    2017-10-01

    Full Text Available Background/Aims: Enterococcal peritonitis in peritoneal dialysis (PD patients is associated with a high complication rate. The optimal treatment regimen of PD-related enterococcal peritonitis is controversial. The latest international guideline recommends intra-peritoneal (IP vancomycin. Although ampicillin is often effective for systemic enterococcal infections, they have little in vitro activity when added to common PD solutions. Since oral amoxicillin achieves therapeutic drug level in the peritoneal cavity, we explore the efficacy of oral amoxicillin for enterococcal peritonitis. Methods: We studied 105 episodes of enterococcal peritonitis over 20 years in our unit; 43 (41.0% were treated with oral amoxicillin, and 62 (59.0% with IP vancomycin. Their clinical outcome was reviewed. Result: The overall primary response rate to oral amoxicillin and IP vancomycin was 76.4% and 85.5%, respectively (p = 0.3. The complete cure rate of oral amoxicillin and IP vancomycin was 55.8% and 54.8%, respectively (p = 0.8. When the 5 episodes of ampicillin-resistant Enterococcus episodes were excluded, the primary response rate and complete cure rate of oral amoxicillin were 86.8% and 63.2%, respectively. Conclusion: Oral amoxicillin has an excellent primary response rate and complete cure rate for PD-related peritonitis episodes caused by Enterococcus species, indicating that oral amoxicillin is a valid and convenient therapeutic option for enterococcal peritonitis episodes.

    ♦ This study was carried out to examine whether or not elderly patients on peritoneal dialysis (PD) had an increased risk of peritonitis. ♦ This was a retrospective cohort study based on data from the French Language Peritoneal Dialysis Registry. We analyzed 8,396 incident patients starting PD between January 2003 and December 2010. The end of the observation period was 31 December 2012. Patients were separated into 2 age groups: up to 75 and over of 75 years old. ♦ Among 8,396 patients starting dialysis there were 3,173 patients older than 75. When using a Cox model, no association was found between age greater than 75 years and increased risk of peritonitis (hazard ratio [HR]: 0.97 [0.88 - 1.07]). Diabetes (HR: 1.14 [1.01 - 1.28] and continuous ambulatory PD (HR: 1.13 [1.04 - 1.23]) were significantly associated with a higher risk of peritoneal infection whereas nurse-assisted PD was associated with a lower risk of peritonitis (HR: 0.85 [0.78 - 0.94]. In the analysis restricted to the 3,840 self-care PD patients, there was no association between age older than 75 years and risk of peritonitis. ♦ The risk of peritonitis is not increased in elderly patients on PD in a country where assisted PD is available.

  17. Radiation therapy of peritoneal mesothelioma

    International Nuclear Information System (INIS)

    Lederman, G.; Recht, A.

    1986-01-01

    The role of radiation therapy in the treatment of peritoneal mesotheliomas remains ill-defined despite its association with the few long-term survivals reported for this disease. The rationale for local therapy is clear as the disease most often is confined to the peritoneal cavity at the time of initial diagnosis and remains there for much of the subsequent course. Effective local treatment of this intra-abdominal disease would likely improve survival. The absence of randomized studies has made analysis of the various treatments of the disease and the few reported success difficult. Nonetheless, scrutiny of the available data may offer insights and guide future clinical trials, as well as the clinician responsible for the treatment of current patients with peritoneal mesothelioma. The radiotherapeutic approach to oncology stresses anatomic considerations in an attempt to understand the patterns of spread of the primary tumor. The observed location and bulk of disease by clinical examination, radiologic study, surgical exploration, and autopsy suggest mechanisms of metastases (direct extension, lymphatic or hematogenous). This dictates the administration of radiation that best achieves a successful outcome

  18. Supporting peritoneal dialysis in remote Australia.

    Carruthers, Dale; Warr, Kevin

    2004-12-01

    Peritoneal dialysis is usually considered a first-choice treatment for end-stage renal disease for patients living in remote areas. The advantages of peritoneal dialysis over haemodialysis are that peritoneal dialysis preserves the residual renal function for longer, provides patients with more independence and gives patients a greater opportunity to return home quickly. In Australia, Aboriginal people suffer end-stage renal failure at disproportionately higher rates than the general population. Given that many Aboriginal people live in remote communities a task of peritoneal dialysis units is to ensure the successful setting up and maintenance of peritoneal dialysis programmes in the outback. This paper examines how peritoneal dialysis units located in the city are able to deliver peritoneal dialysis to patients located often hundreds of kilometres and at times thousands of kilometres away in very remote communities. In preparing this paper interviews were conducted with renal and remote community-based health professionals in Western Australia and the Northern Territory, and with peritoneal dialysis patients in Western Australia. The success of remote peritoneal dialysis programmes relies on many elements, most importantly an integrated approach to care by all members of the peritoneal dialysis team. The peritoneal dialysis team included not just health professionals but also patients, their families, their communities and other support people such as those involved in the transport of peritoneal dialysis supplies to the outback. Careful communication, a willingness to participate, friendliness and delivering care and supplies with a smile are essential ingredients to a winning program. Without all of these ingredients dialysis in the bush may fail.

Assim, a presença de poliminerais, como mica e feldspato; diferentes camadas estratigráficas da Formação Sopa-Brumadinho (quartzitos monomíticos e conglomerados; os lineamentos estruturais e as características geomorfológicas locais são fatores que contribuem para a ocorrência de cavidades na região. A hipótese de formação das cavidades indica a probabilidade de ocorrência de dissolução, produção de materiais inconsolidados, lixiviação, remobilização dos grãos alterados e ampliação dos condutos através de abatimentos.

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

    Sclerosing encapsulating peritonitis (SEP) is a serious complication of peritoneal dialysis (PD) characterized by thickened peritoneal membranes, which lead to decreased ultra-filtration and intestinal obstruction. Its early clinical features are nonspecific, and it is often diagnosed late following laparotomy and peritoneal biopsy, when the patient develops small bowel obstruction, which can be a life-threatening complication. However, this is changing with increasing awareness of computed tomography (CT) findings in SEP. CT can yield an early, non-invasive diagnosis that may improve patient outcome. We present a review of the CT appearances of SEP.

  11. Intraperitoneal pressure in peritoneal dialysis

    2017-11-01

    Full Text Available The measure of intraperitoneal pressure in peritoneal dialysis is easy and provides clear therapeutic benefits. However it is measured only rarely in adult peritoneal dialysis units. This review aims to disseminate the usefulness of measuring intraperitoneal pressure. This measurement is performed in supine before initiating the drain of a manual exchange with “Y” system, by raising the drain bag and measuring from the mid-axillary line the height of the liquid column that rises from the patient. With typical values of 10–16 cm H2O, intraperitoneal pressure should never exceed 18 cm H2O. With basal values that depend on body mass index, it increases 1–3 cm H2O/L of intraperitoneal volume, and varies with posture and physical activity. Its increase causes discomfort, sleep and breathing disturbances, and has been linked to the occurrence of leaks, hernias, hydrothorax, gastro-esophageal reflux and enteric peritonitis. Less known and valued is its ability to decrease the effectiveness of dialysis significantly counteracting ultrafiltration and decreasing solute clearance to a smaller degree. Because of its easy measurement and potential utility, should be monitored in case of ultrafiltration failure to rule out its eventual contribution in some patients. Although not yet mentioned in the clinical practice guidelines for PD, its clear benefits justify its inclusion among the periodic measurements to consider for prescribing and monitoring peritoneal dialysis. Resumen: La medida de la presión intraperitoneal en diálisis peritoneal es muy sencilla y aporta claros beneficios terapéuticos. Sin embargo, su monitorización todavía no se ha generalizado en las unidades de diálisis peritoneal de adultos. Esta revisión pretende divulgar su conocimiento y la utilidad de su medida.

    1991-01-01

    The effect of intraperitoneal bile on growth, peritoneal absorption, and clearance of Escherichia coli was determined in E coli peritonitis in the rat. In E coli peritonitis, intraperitoneal bacterial counts gradually decreased, whereas they increased (after 2 hours) with subsequent development of bacteremia in E coli plus bile peritonitis. After an intraperitoneal injection of labeled bacteria, blood radioactivity was only initially lower in E coli plus bile peritonitis compared with E coli peritonitis. Clearance from blood was lower in E coli plus bile peritonitis than in E coli peritonitis. Organ localization was similar in E coli peritonitis and E coli plus bile peritonitis with decreased splenic, increased pulmonary, and unchanged hepatic uptakes compared with controls. Impaired peritoneal absorption of bacteria, together with impaired local host defense, is likely to enhance the noxious effect of bile in E coli peritonitis

    Loss of peritoneal function due to peritoneal fibrosing syndrome (PFS) is a major factor leading to treatment failure in chronic peritoneal dialysis (PD) patients. Although the precise biologic mechanisms responsible for these changes have not been defined, the general assumption is that alterations in peritoneal function are related to structural changes in the peritoneal membrane. Studies of the peritoneal membrane by non-invasive ultrasonography (US) in chronic PD patients are limited. The aim of the present study is to assess the relationship between functional parameters of peritoneum and peritoneal thickness measured by US in children treated by chronic PD. We recruited two groups of patients: 23 subjects (13 females, 10 males) on chronic PD (patient group) and 26 (7 females, 19 males) on predialysis out-patient follow-up (creatinine clearance: 20-60 mL/min/1.73 m(2)) (control group). Age, sex, weight, height, body mass index (BMI), chronic PD duration, episodes of peritonitis and the results of peritoneal equilibration test (PET) were recorded. Hemoglobin (Hb), blood pressure (BP), left ventricular mass index (LVMI) and renal osteodystrophy (ROD) parameters were also obtained. The thickness of the parietal peritoneum was measured by trans-abdominal US in all children. Statistical analyses were performed by using Student's t and Pearson's correlation tests. Mean peritoneal thickness in chronic PD patients (1028.26 ± 157.26 μm) was significantly higher than control patients (786.52 ± 132.33). Mean peritoneal thickness was significantly correlated with mean body height (R(2) = 0.93, p peritonitis (R(2) = 0.93, p peritoneal thickness and Hb, BP, LVMI and ROD parameters. In conclusion, ultrasonographic measurement of peritoneal membrane thickness is a simple and non-invasive method in chronic PD children. This diagnostic tool likely enables to assess peritoneal structure and function in these patients.

    The peritoneum is a frequent site of involvement by peritoneal tuberculosis. Generally, computed tomography appears to be the imaging modality of choice in the detection and assessment of abdominal tuberculosis. The computed tomography findings can help in the diagnosis of peritoneal tuberculosis, that is confirmed by a positive culture or hystologic analysis of biopsy obtained through laparoscopic examination. Peritoneal carcinomatosis is the main differential diagnosis. In this article we present the spectrum of tomographic manifestation of peritoneal tuberculosis and how we can differentiate it from peritoneal carcinomatosis. (author)

    A study of the process of pharmacokinetics-pharmacodynamics (PKPD) of antibiotics and their interaction with bacteria during peritoneal dialysis associated peritonitis (PDAP) is presented. We propose a mathematical model describing the evolution of bacteria population in the presence of antibiotics for different peritoneal dialysis regimens. Using the model along with experimental data, clinical parameters, and physiological values, we compute variations in PD fluid distributions, drug concentrations, and number of bacteria in peritoneal and extra-peritoneal cavities. Scheduling algorithms for the PD exchanges that minimize bacteria count are investigated.

    Full Text Available It has been confirmed that alternatively activated macrophages (M2 participate in tissue remodeling and fibrosis occurrence, but the effect of M2 on peritoneal fibrosis related to peritoneal dialysis (PD hasn’t been elucidated. This study was therefore conducted to assess the association between M2 and peritoneal fibrosis related to PD. In this study, peritoneal fibrosis was induced by intraperitoneal (i.p. injection of Lactate-4.25% dialysate (100 mL/kg to C57BL/6J mice for 28 days, and liposome-encapsulated clodronate (LC, the specific scavenger of macrophages was used to treat the peritoneal fibrosis mice model by i.p. injection at day 18 and day 21. All animals were sacrificed at day 29. Parietal peritonea were stained with Masson’s trichrome, and the expression of type I collagen (Col-I, fibronectin, mannose receptor (CD206, transforming growth factor beta (TGF-β, chemokine receptor 7 (CCR7, chitinase 3-like 3 (Ym-1 and arginase-1 (Arg-1 was determined by Western blotting, immunofluorescence and quantitative real-time PCR. Our results revealed that peritoneal thickness, Col-I, fibronectin, CD206, TGF-β, Ym-1 and Arg-1 were upregulated in the peritoneal fibrosis mice model, and all of these indexes were downregulated in those treated with LC. Additionally, there was no difference in the level of CCR7 between the model and treatment group. Our study indicated that peritoneal M2 played an important role in the process of peritoneal fibrosis related to PD and might be a potential target for intervention therapy of peritoneal fibrosis.

    Individualized prescription of bicarbonate solutions allows one to control metabolic acidosis. Low sodium solutions improve sodium removal and may become available in the future. Varying dwell time and fill volume when intermittent APD is prescribed improves the efficiency of dialysis. Continuous flow peritoneal dialysis can dramatically improves the efficiency of dialysis. Normalized haemoglobin values by epoietin-beta in renal transplant recipients are associated with a better graft survival at 2 years. Switch from calcineurins inhibitors to sirolimus after the first squamous-cell carcinoma lead to significantly longer survival free of cutaneous carcinoma at 2 years. Eculizumab allowed successful prevention and treatment of atypical haemolytic and uremic syndrome episodes.

    The incidence of end-stage renal disease in children is increasing. Peritoneal dialysis (PD) is the modality of choice in many European countries and is increasingly applied worldwide. PD enables children of all ages to be successfully treated while awaiting the ultimate goal of renal transplantation. The advantages of PD over other forms of renal replacement therapy are numerous, in particular the potential for the child to lead a relatively normal life. Indications for commencing PD, the rationale, preparation of family, technical aspects, and management of complications are discussed. PMID:26504404

    2015-05-01

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

    Two patients with histologically proven diagnosis of peritoneal mesothelioma are presented. Both patients had CT scans of the abdomen. The second patient was also examined with MRI. Although imaging findings are striking, they are non-specific and diagnosing peritoneal mesothelioma in the absence of pleural calcification or pleural plaque on chest radiograph or CT is difficult. However, it is possible to suggest the correct diagnosis in a patient with the presence of non-calcified omental and peritoneal infiltration or masses without liver secondaries or lymphadenopathy. Magnetic resonance imaging with its multi-planar capabilities is a highly sensitive non-invasive modality in the evaluation of malignant peritoneal mesothelioma and can demonstrate the exact site and clarify whether the mass is arising from the peritoneal surface or within a visceral organ.

    Full Text Available Abstract Background There has not been a comprehensive, multi-centre study of streptococcal peritonitis in patients on peritoneal dialysis (PD to date. Methods The predictors, treatment and clinical outcomes of streptococcal peritonitis were examined by binary logistic regression and multilevel, multivariate poisson regression in all Australian PD patients involving 66 centres between 2003 and 2006. Results Two hundred and eighty-seven episodes of streptococcal peritonitis (4.6% of all peritonitis episodes occurred in 256 individuals. Its occurrence was independently predicted by Aboriginal or Torres Strait Islander racial origin. Compared with other organisms, streptococcal peritonitis was associated with significantly lower risks of relapse (3% vs 15%, catheter removal (10% vs 23% and permanent haemodialysis transfer (9% vs 18%, as well as a shorter duration of hospitalisation (5 vs 6 days. Overall, 249 (87% patients were successfully treated with antibiotics without experiencing relapse, catheter removal or death. The majority of streptococcal peritonitis episodes were treated with either intraperitoneal vancomycin (most common or first-generation cephalosporins for a median period of 13 days (interquartile range 8–18 days. Initial empiric antibiotic choice did not influence outcomes. Conclusion Streptococcal peritonitis is a not infrequent complication of PD, which is more common in indigenous patients. When treated with either first-generation cephalosporins or vancomycin for a period of 2 weeks, streptococcal peritonitis is associated with lower risks of relapse, catheter removal and permanent haemodialysis transfer than other forms of PD-associated peritonitis.

    At laparotomy, many surgeons routinely instill crystalloid solutions into the peritoneal cavity, presumably to dilute out necrotic debris, bacteria, and adjuvant substances which foster bacterial growth. We examined the effect on mortality, bacterial growth, clearance, and phagocytosis of various volumes of saline instilled into the peritoneal cavity of rats during Escherichia coli peritonitis. Minimal intraperitoneal bacterial growth was seen after the introduction of a nonlethal inoculum of viable E. coli in 1 ml of saline, while administration of an identical inoculum in 30 ml of saline intraperitoneally (i.p.) led to increased 48-hour mortality (p less than 0.01), and associated rapid bacterial proliferation (p less than 0.01). Clearance of nonviable radiolabelled E. coli from the peritoneal cavity was delayed, bacterial association with host peritoneal leukocytes was decreased, and blood uptake of radiolabelled bacteria was diminished in animals receiving 30 ml of saline i.p., compared to controls which received the identical inoculum in 1 ml of saline i.p. The clinical relevance of these studies is manifold: (1) they provide a possible explanation why patients with ascites due to cirrhosis or the nephrotic syndrome, or those patients undergoing peritoneal dialysis are more susceptible to primary and secondary bacterial peritonitis, possibly on the basis of impaired peritoneal clearance or diminished phagocytosis and, (2) although irrigation of the peritoneal cavity with crystalloid solution would seem prudent during laparotomy, these solutions must be removed prior to closure to prevent interference with normal peritoneal host defense mechanisms.

    Transport characteristics of phosphorus are different from other small solutes that are evaluated in routine peritoneal equilibration test (PET) in peritoneal dialysis (PD) patients. We aimed to evaluate peritoneal phosphorus clearance and permeability, and their relationship with peritoneal membrane transport type and creatinine clearance as well as factors affecting peritoneal phosphorus clearance. 70 adult patients on a PD program were included in our study. Phosphorus transport status was classified according to dialysate/plasma (D/P) phosphorus at the 4th hour of PET as slow transporter ( 0.67). We evaluated the relationship of peritoneal phosphorus clearance and transport type with PD regime, phosphorus level, and presence of residual renal function in addition to investigating factors that are effective on peritoneal phosphorus clearance. D/P phosphorus and peritoneal phosphorus clearance were positively correlated with D/P creatinine and peritoneal creatinine clearance, respectively. Automated PD and continuous ambulatory PD patients were similar regarding phosphorus and creatinine clearances and transport status based on D/P phosphorus. The major determinant of peritoneal phosphorus clearance was anuria status. Anuric patients had higher dialysate volume (11.6 ± 3.0 L vs. 8.4 ± 2.1 L, p peritoneal phosphorus clearance (61.7 ± 15.1 L/week/1.73 m2 vs. 48.4 ± 14.0 L/week/1.73 m2, p = 0.001). Hyperphosphatemia was present in 40% and 11% of anuric patients and those with residual renal function, respectively (p = 0.005). Peritoneal phosphorus transport characteristics are similar to that of creatinine. Although increased dialysis dose may increase peritoneal phosphorus clearance, it may be insufficient to prevent hyperphosphatemia in anuric patients.

    Diffuse malignant peritoneal mesothelioma (MPM) is a rare and ultimately fatal cancer that was first described just over a century ago. It is a diffuse malignancy arising from the mesothelial lining of the peritoneum; morbidity and mortality from MPM is due to its propensity to progress locoregionally within the abdominal cavity. The purpose of this article is to review the current state-of-the-science related to the diagnosis, staging, and treatment of MPM. The condition afflicts men and women equally and the peak incidence is between 55 and 60 years of age although it can arise in the young and elderly. Patients afflicted with MPM most commonly present with nonspecific abdominal symptoms that usually lead to diagnosis when the condition is relatively advanced. Historically, median overall survival for MPM patients without treatment is < 1 year. The couplet of systemic pemetrexed and cisplatin has an overall response rate of approximately 25% and a median overall survival of approximately 1 year. The available data, almost all retrospective in nature, have shown that in selected patients, operative cytoreduction (CRS) and regional chemotherapy administered as hyperthermic intraoperative peritoneal chemotherapy (HIPEC) or early postoperative intraperitoneal chemotherapy (EPIC) is associated with long-term survival. Studies on the molecular biology of MPM have yielded new insights relating to the potentially important role of the phosphoinsitide-3-kinase/mammalian target of rapamycin (PI3 K/mTOR) pathways and immune checkpoint inhibitors that may translate into new therapeutic options for patients with diffuse MPM.

  1. Phosphate Removal by Peritoneal Dialysis: The Effect of Transporter Status and Peritoneal Dialysis Prescription

    Courivaud, Cecile; Davenport, Andrew

    2016-01-01

    ♦ Background: Interventional trials failed to demonstrate that increasing urea clearance improved peritoneal dialysis (PD) patient survival. Hyperphosphatemia is a well-recognized predictor of cardiovascular and all-cause mortality in PD patients. Simplification of PD small solute clearance targets focuses away from larger solutes, including phosphate. In the US and UK, increasing use of automated peritoneal dialysis (APD) cyclers with shorter dwell times could also potentially reduce peritoneal phosphate removal compared to continuous ambulatory peritoneal dialysis (CAPD). ♦ Methods: Total phosphate and peritoneal phosphate clearances were measured in a prospective observational cohort of 380 adult PD patients attending a tertiary university hospital between 1996 and 2013 for routine assessment of PD adequacy. ♦ Results: Eighty-seven patients (22.9%) were hyperphosphatemic. Taking the mean 4-hour dialysate to plasma (D/P) ratio for phosphate, 193 (50.8%) were fast and fast-average transporters and 187 (49.2%) were slow and slow-average transporters (compared to 276 [72.6%] and 104 [27.4%], respectively, for peritoneal creatinine transporter status). Faster peritoneal phosphate transporter status was associated with over-hydration (odds ratio [OR] = 2.45 [1.43 – 4.20], p = 0.001). Whereas the 4-hour D/P creatinine and peritoneal weekly creatinine clearance did not differ between those who were hyperphosphatemic or not, the hyperphosphatemic patients had lower 4-hour D/P phosphate and lower peritoneal weekly phosphate clearance (p = 0.019, and p = 0.06 respectively). We found greater peritoneal phosphate clearance for patients choosing CAPD compared to APD, irrespective of the peritoneal phosphate transporter status. ♦ Conclusion: Peritoneal creatinine transporter status and creatinine clearance cannot be used as surrogate markers of peritoneal phosphate transport and clearance. Hyperphosphatemia was more common in PD patients with slower peritoneal

    Interference of conventional peritoneal dialysis fluids (cPDFs) with peritoneal membrane cell functions may be attributed to the dialysis fluid's low pH, high glucose concentration, and/or the presence of glucose degradation products (GDPs), the last of which leads to higher levels of advanced glycation end-products (AGEs). It has been suggested that the peritoneal membrane might be better preserved by using biocompatible solutions, including cancer antigetn 125 (CA125). This prospective, open-label, multicentre, randomized, controlled, cross-over phase IV study compared the in vivo biocompatibility of a neutral-pH, low-GDP peritoneal dialysis (PD) solution (balance) with a cPDF in automated PD (APD) patients. Our study revealed a significantly increased appearance rate and concentration of CA125 in the peritoneal effluent of APD patients treated with the neutral-pH, low-GDP solution balance versus a conventional PD solution.

    Full Text Available Treatment of cancers in the abdominal cavity, such as peritoneal dissemination, is difficult, but in principle intraperitoneal administration of anticancer drugs is expected to be preferable to systemic administration. Taxane anticancer drugs are used to treat gastric cancer patients with peritoneal dissemination. They are administered as micellar preparations, Taxol and Taxotere, which consist of paclitaxel in Cremophor EL (crEL and docetaxel in Polysorbate-80 (PS-80, respectively. In this paper we review the disposition kinetics of taxane anticancer drugs after intraperitoneal administration in peritoneal dissemination patients and animal models and also discuss the effect of the surfactant vehicle on the behavior of taxanes.

    Peritonitis continues to be one of the major infectious problems confronting surgeons. Despite the many advances in antimicrobial agents and supportive care, mortality from diffuse suppurative peritonitis remains unacceptably high. The authors review the anatomy and defense capabilities of the peritoneal cavity and then focus on the polymicrobial nature of peritonitis and how, through microbial interactions with host defenses, there is either resolution or persistent infection. They also consider possible infection-potentiating agents in the peritoneal cavity and experimental modes of therapy.

    Full Text Available Pseudomonas stutzeri is a Gram-negative, rod-shaped, motile, single polar-flagellated, soil bacterium that was first isolated from human spinal fluid and is widely distributed in the environment. It was isolated as an uncommon opportunistic pathogen from humans, and a few cases of P. stutzeri-induced peritonitis have been reported in patients undergoing continuous ambulatory peritoneal dialysis (CAPD. Catheter removal with antibiotic treatment is generally recommended because peritonitis by Pseudomonas species is commonly associated with catheter-related infection. Here, we describe the first case of P. stutzeri-induced peritonitis in an 82-year-old woman in Korea. She had received two antipseudomonal antibiotics, an aminoglycoside (isepamicin, Yuhan corporation, Seoul, Korea and a fluoroquinolone (ciprofloxacin, and was successfully treated without removal of the CAPD catheter.

    Full Text Available Leiomyosarcomas of soft tissue are the rare tumors and the retroperitoneum is the most common site involved. We report a case of primary leiomyosarcoma of the peritoneal cavity which clinically presented with suprapubic, freely mobile, nontender mass which measured 10×10 cm in size. Contrast enhanced computed tomography revealed well defined heterogenous hypodense solid cystic mass. The mass was surgically excised out in its entirety. The histopathological examination revealed spindle cells arranged in alternating fascicles having pleomorphic nuclei, indistinct margin and eosinophilic cytoplasm with foci of haemorrhage, necrosis and 5-6 mitosis/HPF. The spindle cells were immunoreactive for smooth muscle actin, desmin and negative for S-100, CD-34 and c-kit. Histopathology and immunohistochemistry were helpful in making the final confirmatory diagnosis. Leiomyosarcomas are aggressive tumors, with poor prognosis and often difficult to treat. The survival rates are lowest among all soft tissue sarcomas.

  10. Optimising intraperitoneal gentamicin dosing in peritoneal dialysis patients with peritonitis (GIPD study

    Lipman Jeffrey

    2009-12-01

    Full Text Available Abstract Background Antibiotics are preferentially delivered via the peritoneal route to treat peritonitis, a major complication of peritoneal dialysis (PD, so that maximal concentrations are delivered at the site of infection. However, drugs administered intraperitoneally can be absorbed into the systemic circulation. Drugs excreted by the kidneys accumulate in PD patients, increasing the risk of toxicity. The aim of this study is to examine a model of gentamicin pharmacokinetics and to develop an intraperitoneal drug dosing regime that maximises bacterial killing and minimises toxicity. Methods/Design This is an observational pharmacokinetic study of consecutive PD patients presenting to the Royal Brisbane and Women's Hospital with PD peritonitis and who meet the inclusion criteria. Participants will be allocated to either group 1, if anuric as defined by urine output less than 100 ml/day, or group 2: if non-anuric, as defined by urine output more than 100 ml/day. Recruitment will be limited to 15 participants in each group. Gentamicin dosing will be based on the present Royal Brisbane & Women's Hospital guidelines, which reflect the current International Society for Peritoneal Dialysis Peritonitis Treatment Recommendations. The primary endpoint is to describe the pharmacokinetics of gentamicin administered intraperitoneally in PD patients with peritonitis based on serial blood and dialysate drug levels. Discussion The study will develop improved dosing recommendations for intraperitoneally administered gentamicin in PD patients with peritonitis. This will guide clinicians and pharmacists in selecting the most appropriate dosing regime of intraperitoneal gentamicin to treat peritonitis. Trial Registration ACTRN12609000446268

  11. microRNA Regulation of Peritoneal Cavity Homeostasis in Peritoneal Dialysis

    2015-01-01

    Full Text Available Preservation of peritoneal cavity homeostasis and peritoneal membrane function is critical for long-term peritoneal dialysis (PD treatment. Several microRNAs (miRNAs have been implicated in the regulation of key molecular pathways driving peritoneal membrane alterations leading to PD failure. miRNAs regulate the expression of the majority of protein coding genes in the human genome, thereby affecting most biochemical pathways implicated in cellular homeostasis. In this review, we report published findings on miRNAs and PD therapy, with emphasis on evidence for changes in peritoneal miRNA expression during long-term PD treatment. Recent work indicates that PD effluent- (PDE- derived cells change their miRNA expression throughout the course of PD therapy, contributing to the loss of peritoneal cavity homeostasis and peritoneal membrane function. Changes in miRNA expression profiles will alter regulation of key molecular pathways, with the potential to cause profound effects on peritoneal cavity homeostasis during PD treatment. However, research to date has mainly adopted a literature-based miRNA-candidate methodology drawing conclusions from modest numbers of patient-derived samples. Therefore, the study of miRNA expression during PD therapy remains a promising field of research to understand the mechanisms involved in basic peritoneal cell homeostasis and PD failure.

    Peritoneal protein clearance (Pcl) is related to the mortality of patients on continuous ambulatory peritoneal dialysis (CAPD) as well as technique failure. In this prospective observational study, we aimed to investigate factors associated with the level of Pcl. We prospectively enrolled 344 prevalent CAPD patients. A standard peritoneal equilibrium test was conducted for each patient. Baseline demographics, biochemistry, and Pcl were recorded. The average Pcl of the patients was 97.40 ± 54.14 mL/day. Peritoneal transport level, serum high-sensitivity C-reactive protein (hsCRP), and residual glomerular filtration rate (rGFR) were independently related to Pcl. The standard β values were 0.53, 0.17, and -0.10, respectively. Moreover, compared with non-diabetic patients, diabetic patients had a non-significantly higher level of Pcl (104.90 ± 48.65 vs. 96.15 ± 54.97 mL/day; P = 0.06). Continuous ambulatory peritoneal dialysis patients lose a high amount of protein through the peritoneum each day. The Pcl value is positively related to the level of peritoneal transport and hsCRP and negatively related to the rGFR.

En esta controversia revisamos el defecto óseo del seno maxilar y las cavidades residuales postquistectomía, ambos defectos de tamaño no crítico que conservan varias de sus paredes. En la elevación de seno muchos autores concluían que era necesario aportar siempre hueso autólogo en el material de injerto, bien en solitario o en distintas mezclas con biomateriales en proporciones no definidas, 50:50, 20:80 etc. La evidencia clínica y la que recoge la literatura en los últimos años contradice esa conclusión y ya se afirma que los biomateriales en exclusiva en el seno maxilar consiguen resultados equiparables al hueso autólogo siempre que se aumente el periodo de osificación. Repasamos nuevos estudios que incluso discuten la necesidad de utilizar ningún tipo de injerto para conseguir neoformación ósea dentro del seno maxilar. Los resultados en el defecto óseo de cavidades residuales postquistectomía, en las que consigamos mantener varias de sus paredes, son todavía más concluyentes. El mejor tratamiento de esos defectos es el cierre directo de la mucosa y esperar a la regeneración espontánea del defecto. La utilización de hueso autólogo es innecesaria y si aportamos biomateriales tampoco conseguimos un mejor comportamiento biomecánico del hueso residual, retrasamos la osificación y aumentamos el número de complicaciones. Sólo los defectos de espesor total pueden beneficiarse de la utilización de membranas. Los defectos que han perdido varias paredes pueden perder su capacidad de regeneración

    Although varying widely among different countries and geographic regions, the development of peritoneal dialysis invariably requires a well-established program. Key ingredients for the successful delivery of this therapy include adequate chronic kidney disease education, governmental or nongovernmental reimbursement, qualified physicians and nurses trained in the principles and practice of peritoneal dialysis, clinical management that incorporates an excellent and well-trained peritoneal dialysis team, a feasible and well-designed program for catheter insertion, a sound patient training and follow-up scheme, and continuous quality improvement. Some programs are enhanced by an active clinical research portfolio and other appropriate supportive systems. All of these factors are interlinked and inseparable from one another in ensuring a high-quality peritoneal dialysis program. Copyright © 2017 Elsevier Inc. All rights reserved.

    2013-08-26

    A 63-year-old woman with no medical history underwent an abdominal surgery with hysterectomy and bilateral salpingo-oophorectomy for a 10 cm peritoneal cyst with increased cancer antigene-125. A large suspicious tumour of the Douglas space, with contact to the uterus and the rectal wall was described. The rest of the exploration was normal, specially the rest of the peritoneum. Histopathology revealed a malignant transformation of a superficial peritoneal endometriosis. Secondary surgery was thus completed by laparoscopy with bilateral pelvic and para-aortic lymph node dissections, omentectomy and multiple peritoneal biopsies. All staging samples were free of cancer; therefore no complementary therapy was administered. After 18 months of follow-up, consisting of clinical examination and pelvis magnetic resonance imaging every 6 months, we did not observe any recurrence. Malignant transformation of superficial peritoneal endometriosis is a rare disease and surgical management seems to be the main treatment.

    Pelvic-peritoneal tuberculosis is a common extrapulmonary site in young females mimicking an advanced ovarian malignancy. We present 2 cases with the classical triad of advanced-stage ovarian carcinoma-ascites, abdominopelvic masses and elevated serum CA-125 levels. Laparoscopic examination revealed peritoneal nodules which on biopsy showed granulomatous inflammation and no malignant cells. Patients were started on anti-tuberculous therapy and on follow-up their symptoms as well as CA-125 levels normalized. Medical awareness of peritoneal tuberculosis is lacking and many young women with this disease undergo unnecessary extended surgery. Diagnostic laparoscopy combined with peritoneal biopsy seems to be a sufficient and safe method to provide a definitive diagnosis for this curable infection. If left untreated, the disease may disseminate and result in significant organ dysfunctions particularly infertility. (author)

    Mesothelial reaction simulating peritoneal diffuse malignant mesothelioma (MM) has been reported in the setting of Crohn ileitis. To our knowledge, peritoneal MM arising in patients with inflammatory bowel disease (IBD) has not been reported. The purpose of this study is to report the clinicopathological characteristics of patients with peritoneal MM and IBD. A database of approximately 3800 MM was reviewed for cases of MM in patients with IBD. Three patients (0.08%) with peritoneal MM and Crohn disease (CD) were identified, including two women and one man ranging in age from 56 to 65 years. All had a long-standing history of diarrhoea and an established diagnosis of CD of 3 years or greater duration. Two had epithelial MM and one had biphasic MM. Only one had documented asbestos exposure. Peritoneal MM occurs rarely in patients with IBD, but interestingly, has only been observed in the setting of CD and not in patients with ulcerative colitis. Chronic inflammation has been associated with the development of MM in rare instances and these three cases suggest that CD with transmural inflammation may also be a precursor. The precise role of CD-related transmural inflammation in the carcinogenesis of peritoneal MM remains to be determined. Published by the BMJ Publishing Group Limited.

    Peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD) is the leading cause of technique failure. Information on the impact of non-compliance in performing CAPD exchange on peritonitis is limited. We aimed to find the prevalence of non-compliance to the CAPD procedure and its influence on the incidence of peritonitis. This observational study included 30 adult patients undergoing CAPD. The CAPD exchange procedure was observed at home and assessed as per the structured checklist and categorized into poor, average and good compliance. The compliance was correlated with the episodes of peritonitis in previous 1 year. The patients' mean age was 52 ± 13 years and the mean duration of CAPD was 2.1 ± 0.9 years. Only 16.5% of patients were good performers, while 67% were average performers, and 16.5% were poor performers. The technique skill was similar across all the steps of the procedure. The most common improperly performed steps were: not putting on a face mask in 68%, not flushing the tubing system in 60%, and not washing hands in 24%. Poor adherence to procedure was independent of age, gender, education and duration of dialysis. Ten episodes of peritonitis occurred in 5 patients over 1-year period. Peritonitis occurred in 60% of poor performers, whereas fully compliant patients had no peritonitis. Also 40% of the poorly compliant patients had multiple episodes of peritonitis. Poor compliance in performing the CAPD procedure is a modifiable risk factor for peritonitis. Adherence to recommended aseptic technique is the cornerstone of peritonitis prevention.

Describimos dos casos de hidrotórax que aparecieron después de tres meses de inicio de la DP, cursaron con derrame pleural derecho, tos, disnea y disminución del volumen de drenaje, el diagnostico se realizo mediante radiografía de tórax, toracentesis y gammagrafía con infusión intraperitoneal del radioisótopo. Los dos casos se resolvieron con la suspensión de la diálisis peritoneal. En base a la relación existente entre la PIP y la aparición de fugas de líquido hacia diferentes cavidades entre ellas la cavidad pleural, podría ser interesante medir y monitorizar los resultados de la Presión Intraperitoneal como parte de la rutina de las actividades enfermeras. Para realizar la gammagrafía, la colaboración entre la Enfermería de DP y Medicina Nuclear permite la administración del radioisótopo de forma segura e indolora.

    Full Text Available Aim: To determine the risk factors and outcome of fungal peritonitis in continuous ambulatory peritoneal dialysis (CAPD patients over a 7-year period. Patients and Methods: This retrospective study was conducted on 30 cases of fungal peritonitis in CAPD patients during a 7-year period (2000-2007. The diagnosis was based on elevated CAPD effluent count and isolation of fungi. Patients were evaluated for previous episode of bacterial peritonitis. Results: The incidence of fungal peritonitis was 16.2%. Age varied between 8 and 75 years, with a mean age of 57 years. Twenty-three were males (76.7% and seven were females (23.3%. Seventeen patients (56.6% had previous episodes of bacterial peritonitis that was treated with multiple antibiotics. The common fungus was Candida species (50%. CAPD catheter removal and initiation of antifungal therapy was done for all patients. Reinsertion was done for three (10% patients. Mortality rate was 20%. Conclusion: Patients with previous bacterial peritonitis and antibiotic usage are at greater risk of developing fungal peritonitis.

    CA125 in peritoneal dialysis (PD) effluent dialysate has been used as a surrogate biomarker for the health of the peritoneum in PD patients. However CA125 is synthesised by epithelial cells and as such is not specific for the peritoneum, and most studies have only measured peritoneal CA125, without serum CA125 values. As such we wished to determine the factors which influenced PD effluent CA125 in a large contemporaneous cohort. We measured dialysate effluent CA125 in PD patients attending for routine assessment of peritoneal membrane function with a peritoneal equilibration test (PET), with corresponding serum CA125. Serum and dialysate CA125 were measured in 205 PD patients; 59.0 ± 16.8 years, median PD treatment 3 (2-20) months, 59 % male, 42.4 % diabetic, with 31.2 % treated by continuous ambulatory peritoneal dialysis, 22 % by automated overnight peritoneal dialysis cycler (APD) and 46.8 % by APD with a day time exchange. The median serum CA125 was 21 (13-38) U/ml, with an effluent 4 h PD PET effluent of 20 (11.5-36.5) U/ml. PET PD effluent dialysate was associated with PET dialysate total protein (β 12.9, p peritonitis episodes. PD effluent CA125 concentrations were associated with peritoneal protein losses and increased by the usage of higher glucose dialysates to compensate for loss of residual renal function.

  14. Preclinical assessment of adjunctive tPA and DNase for peritoneal dialysis associated peritonitis.

    Directory of Open Access Journals (Sweden)

    Amanda L McGuire

    Full Text Available A major complication of peritoneal dialysis is the development of peritonitis, which is associated with reduced technique and patient survival. The inflammatory response elicited by infection results in a fibrin and debris-rich environment within the peritoneal cavity, which may reduce the effectiveness of antimicrobial agents and predispose to recurrence or relapse of infection. Strategies to enhance responses to antimicrobial agents therefore have the potential to improve patient outcomes. This study presents pre-clinical data describing the compatibility of tPA and DNase in combination with antimicrobial agents used for the treatment of PD peritonitis. tPA and DNase were stable in standard dialysate solution and in the presence of antimicrobial agents, and were safe when given intraperitoneally in a mouse model with no evidence of local or systemic toxicity. Adjunctive tPA and DNase may have a role in the management of patients presenting with PD peritonitis.

    Full Text Available Sphingomonas paucimobilis is an aerobic Gram-negative bacillus found in soil and water. Knowledge regarding the role of this infectious agent is limited because it is rarely isolated from human material. Furthermore, it is an unusual pathogen in cases of peritoneal dialysis (PD-associated peritonitis. The clinical courses and outcomes of peritonitis caused by S. paucimobilis are variable. Whereas some patients were cured with appropriate antibiotic therapy, others required catheter removal. Cases of PD-associated peritonitis caused by S. paucimobilis have been reported worldwide, and there was a case report of coinfection with S. paucimobilis and Chryseobacterium indologenes in Korea. However, there has been no case caused by S. paucimobilis as a single pathogen. We report a case of PD-associated peritonitis due to S. paucimobilis in which the patient recovered after catheter removal.

    Peritonitis is a serious infection and early diagnosis and treatment is mandatory. A variety of microorganisms are identified in these cases and during recent years a new one was included, Pantoea agglomerans. In this case report, a female patient on continuous ambulatory peritoneal dialysis therapy with a peritonitis episode caused by this organism is described. The source of infection was thought to be due to contact of catheter with non-sterile surfaces. In microbiologic culture, this organism was identified and the patient successfully treated with a three week course of gentamicin therapy. The number of reported cases with this organism has increased in last years and various infection localizations and clinical progress patterns have been identified. In peritoneal dialysis patients presenting with peritonitis, this organism must be kept in mind.

    Sclerosing encapsulating peritonitis is a well recognized, but uncommon, complication of chronic ambulatory peritoneal dialysis. I report a case of sclerosing encapsulating peritonitis in which percutaneous catheter drainage was performed preoperatively. Ultrasonography(US) and computed tomography(CT) showed a large multi-septated cystic mass which occupied nearly all the peritoneal cavity. Percutaneous drainage with two 8.5 French catheters was preoperatively performed under fluoroscopy and about 2100 ml of bloody fluid was drained for 20 days. On follow-up CT, the size of the cyst had significantly decreased and anoperation was performed. It is considered that percutaneous catheter drainage is useful in the preoperative decompression of sclerosing encapsulating peritonitis.

Random sampling of nurses to complete a written survey from the International Society for Peritoneal Dialysis Nursing Liaison Committee. United States, Canada, South America (Brazil, Columbia), The Netherlands, Hong Kong. Surveys and responses were sent by fax whenever possible, or by regular mail, or hand carried, or conducted by telephone. Results were stratified by geographic areas as well as by cumulative responses and were expressed as medians with ranges. Kruskal-Wallis was used to evaluate differences in responses. Associations between variables were tested with Pearson correlation. Univariate regression analysis was used to evaluate the impact of variables on peritonitis rates. Variables with p training from a nurse colleague, 11% were guided by a corporate colleague, and 8% were simply self-taught. Clinics responding had a median of 30 PD patients (range 1-400) and reported they trained a median of 8 patients per year (range 0-86). Reported peritonitis rates were a median 0.46 per year or 1 episode every 26 months. Peritonitis rates, however, were not known by 53% of respondents. Total training time per patient had a very wide range of hours, from 6 to 96. There was no correlation between training time and peritonitis rates among the study respondents (p = 0.38), nor with any other variables. There is wide variation in practices for PD patient training programs within countries and around the world. Training time did not appear to be related to peritonitis rates. Randomized trials of training practices are needed to determine which approaches produce the best outcomes for patients.

    There is limited available evidence regarding the role of monitoring serum vancomycin concentrations during treatment of peritoneal dialysis (PD)-associated peritonitis. A total of 150 PD patients experiencing 256 episodes of either gram-positive or culture-negative peritonitis were included to investigate the relationship between measured serum vancomycin within the first week and clinical outcomes of cure, relapse, repeat or recurrence of peritonitis, catheter removal, temporary or permanent transfer to hemodialysis, hospitalization and death. Vancomycin was used as an initial empiric antibiotic in 54 gram-positive or culture-negative peritonitis episodes among 34 patients. The median number of serum vancomycin level measurements in the first week was 3 (interquartile range; IQR 1 - 4). The mean day-2 vancomycin level, measured in 34 (63%) episodes, was 17.5 ± 5.2 mg/L. Hospitalized patients were more likely to have serum vancomycin levels measured on day 2 and ≥ 3 measurements in the first week. The peritonitis cure rates were similar between patients with vancomycin levels were measured or not (68% vs 65%, p = 0.84). The average day-2 (18.0 ± 5.9 vs 16.6 ± 3.2, p = 0.5), first-week average (18.6 ± 5.1 vs 18.6 ± 4.3, p = 0.9) and nadir (14.5 ± 4.1 vs 13.6 ± 4.2, p = 0.5) vancomycin levels were comparable in patients who did or did not achieve peritonitis cure. Similar results were observed for all other clinical outcomes. The clinical outcomes of gram-positive and culture-negative peritonitis episodes are not associated with either the frequency or levels of serum vancomycin measurements in the first week of treatment when vancomycin is dosed according to International Society for Peritoneal Dialysis (ISPD) Guidelines.

    The WNT signaling pathway is involved in wound healing and fibrosis. We evaluated the WNT signaling pathway in peritoneal membrane injury. We assessed WNT1 protein expression in the peritoneal effluents of 54 stable peritoneal dialysis (PD) patients and WNT-related gene expression in ex vivo mesothelial cell cultures from 21 PD patients. In a transforming growth factor beta (TGFB) mediated animal model of peritoneal fibrosis, we evaluated regulation of the WNT pathway and the effect of WNT inhibition on peritoneal fibrosis and angiogenesis. WNT1 and WNT2 gene expression were positively correlated with peritoneal membrane solute transport in PD patients. In the mouse peritoneum, TGFΒ-induced peritoneal fibrosis was associated with increased expression of WNT2 and WNT4. Peritoneal b-catenin protein was significantly upregulated after infection with AdTGFB along with elements of the WNT signaling pathway. Treatment with a b-catenin inhibitor (ICG-001) in mice with AdTGFB-induced peritoneal fibrosis resulted in attenuation of peritoneal angiogenesis and reduced vascular endothelial growth factor. Similar results were also observed with the WNT antagonist Dickkopf related protein (DKK) 1. In addition to this, DKK-1 blocked epithelial to mesenchymal transition and increased levels of the cell adhesion protein E-cadherin. We provide evidence that WNT signaling is active in the setting of experimental peritoneal fibrosis and WNT1 correlates with patient peritoneal membrane solute transport in PD patients. Intervention in this pathway is a possible therapy for peritoneal membrane injury.

    Full Text Available High mobility group box 1 (HMGB1, a DNA-binding nuclear protein, has been implicated as an endogenous danger signal in the pathogenesis of infection diseases. However, the potential role and source of HMGB1 in the peritoneal dialysis (PD effluence of patients with peritonitis are unknown. First, to evaluate HMDB1 levels in peritoneal dialysis effluence (PDE, a total of 61 PD patients were enrolled in this study, including 42 patients with peritonitis and 19 without peritonitis. Demographic characteristics, symptoms, physical examination findings and laboratory parameters were recorded. HMGB1 levels in PDE were determined by Western blot and ELISA. The concentrations of TNF-α and IL-6 in PDE were quantified by ELISA. By animal model, inhibition of HMGB1 with glycyrrhizin was performed to determine the effects of HMGB1 in LPS-induced mice peritonitis. In vitro, a human peritoneal mesothelial cell line (HMrSV5 was stimulated with lipopolysaccharide (LPS, HMGB1 extracellular content in the culture media and intracellular distribution in various cellular fractions were analyzed by Western blot or immunofluorescence. The results showed that the levels of HMGB1 in PDE were higher in patients with peritonitis than those in controls, and gradually declined during the period of effective antibiotic treatments. Furthermore, the levels of HMGB1 in PDE were positively correlated with white blood cells (WBCs count, TNF-α and IL-6 levels. However, pretreatment with glycyrrhizin attenuated LPS-induced acute peritoneal inflammation and dysfunction in mice. In cultured HMrSV5 cells, LPS actively induced HMGB1 nuclear-cytoplasmic translocation and release in a time and dose-dependent fashion. Moreover, cytosolic HMGB1 was located in lysosomes and secreted via a lysosome-mediated secretory pathway following LPS stimulation. Our study demonstrates that elevated HMGB1 levels in PDE during PD-related peritonitis, at least partially, from peritoneal mesothelial cells

    Full Text Available INTRODUCTION: Continuous ambulatory peritoneal dialysis (CAPD peritonitis may develop after endoscopic procedures, and the benefit of prophylactic antibiotics is unclear. In the present study, we investigated whether prophylactic antibiotics reduce the incidence of peritonitis in these patients. PATIENTS AND METHODS: We retrospectively reviewed all endoscopic procedures, including esophagogastroduodenoscopy (EGD, colonoscopy, sigmoidoscopy, cystoscopy, hysteroscopy, and hysteroscopy-assisted intrauterine device (IUD implantation/removal, performed in CAPD patients at Chang Gung Memorial Hospital, Taiwan, between February 2001 and February 2012. RESULTS: Four hundred and thirty-three patients were enrolled, and 125 endoscopies were performed in 45 patients. Eight (6.4% peritonitis episodes developed after the examination. Antibiotics were used in 26 procedures, and none of the patients had peritonitis (0% vs. 8.1% without antibiotic use; p=0.20. The peritonitis rate was significantly higher in the non-EGD group than in the EGD group (15.9% [7/44] vs. 1.2% [1/81]; p<0.005. Antibiotic use prior to non-EGD examinations significantly reduced the endoscopy-associated peritonitis rate compared to that without antibiotic use (0% [0/16] vs. 25% [7/28]; p<0.05. Peritonitis only occurred if invasive procedures were performed, such as biopsy, polypectomy, or IUD implantation, (noninvasive procedures, 0% [0/20] vs. invasive procedures, 30.4% [7/23]; p<0.05. No peritonitis was noted if antibiotics were used prior to examination with invasive procedures (0% [0/10] vs. 53.8% [7/13] without antibiotic use; p<0.05. Although not statistically significant, antibiotics may play a role in preventing gynecologic procedure-related peritonitis (antibiotics, 0% [0/4] vs. no antibiotics, 55.6% [5/9]; p=0.10. CONCLUSION: Antibiotic prophylaxis significantly reduced endoscopy-associated PD peritonitis in the non-EGD group. Endoscopically assisted invasive procedures, such

    The elderly patients are the fastest-growing end-stage renal disease (ESRD) population in Taiwan. Assisted peritoneal dialysis (PD) has been employed to overcome the barriers to PD. The aim of this retrospective, single-center study was to describe the status of assisted PD and the impact of type of assistance on peritonitis in elderly patients in Taiwan. One hundred and two patients initiated PD at the age of 65 or older between 2000 and 2008; 79 episodes of peritonitis occurred during the follow-ups. The patients and episodes of peritonitis were divided into three groups based on the type of assistance: (1) self-care: patients performing dialysis independently, (2) family: patients whose dialysis was performed by family, (3) caregiver: patients whose dialysis was performed by a private caregiver. Patient characteristics and incidence, etiology and outcomes of peritonitis were compared. There were 26 (25.5%), 44 (43.1%), and 32 (31.4%) patients in the self-care, family, and caregiver groups, respectively. The overall peritonitis rate was 1/33 patient-months. Patients in the caregiver group were older and had more comorbidities than the self-care group. They had a trend of higher overall peritonitis rate (1/24 patient-months, P = 0.077) and fungal peritonitis rate (P = 0.060) compared to the self-care and family groups, but this was statistically non-significant. Three-fourths of elderly PD patients in the present study required assistance from family members or private caregivers. Caregiver-assisted patients were significantly older and had more comorbidities. Also, a non-significant trend of higher peritonitis incidence was observed in these patients.

    ♦ BACKGROUND: Peritonitis is the most important complication of peritoneal dialysis (PD), and early peritonitis rate is predictive of the subsequent course on PD. Our aim was to calculate the early peritonitis rate and to identify characteristics and predisposing factors in a large nationwide PD provider network in Colombia. ♦ METHODS: This was a historical observational cohort study of all adult patients starting PD between January 1, 2012, and December 31, 2013, in 49 renal facilities in the Renal Therapy Services in Colombia. We studied the peritonitis rate in the first 90 days of treatment, its causative micro-organisms, its predictors and its variation with time on PD and between individual facilities. ♦ RESULTS: A total of 3,525 patients initiated PD, with 176 episodes of peritonitis during 752 patient-years of follow-up for a rate of 0.23 episodes per patient year equivalent to 1 every 52 months. In 41 of 49 units, the rate was better than 1 per 33 months, and in 45, it was better than 1 per 24 months. Peritonitis rates did not differ with age, ethnicity, socioeconomic status, or PD modality. We identified high incidence risk periods at 2 to 5 weeks after initiation of PD and again at 10 to 12 weeks. ♦ CONCLUSION: An excellent peritonitis rate was achieved across a large nationwide network. This occurred in the context of high nationwide PD utilization and despite high rates of socioeconomic deprivation. We propose that a key factor in achieving this was a standardized approach to management of patients. Copyright © 2017 International Society for Peritoneal Dialysis.

    We provided partial peritoneal alimentation to a 1.69-kg 11-month-old premature infant who had no available central venous access, depleted peripheral venous access, and gastrointestinal dysfunction. A cuffed silastic catheter was surgically inserted into the suprahepatic space. An alimentation solution was continuously infused into the peritoneum for 28 days to supplement peripheral venous and nasogastric alimentation and contributed 42 +/- 15% of total calories daily. Weight gain was achieved, but complications included hypoglycemia, hypophosphatemia, intravascular dehydration, catheter site leakage, ascites, and hydrocele. At autopsy 11 months later, lipid accumulation was present in the upper peritoneum and the hilar regions of the lungs secondary to preexisting lymphatic obstruction. Partial peritoneal alimentation may be feasible when other access routes are inadequate, but lymphatic obstruction is a contraindication to the peritoneal administration of lipid emulsions.

    Full Text Available Background. Mesothelioma is a rare cancer with a historically dire prognosis. We sought to calculate life expectancies for patients with pleural or peritoneal mesothelioma, both at time of diagnosis and several years later, and to examine whether survival has improved in recent years. Methods. Data on 10,258 pleural and 1,229 peritoneal patients from the SEER US national cancer database, 1973–2011, were analyzed using the Cox proportional hazards regression model. Results. The major factors related to survival were age, sex, stage, grade, histology, and treatment. Survival improved only modestly over the study period: 0.5% per year for pleural and 2% for peritoneal. Conclusions. Life expectancies were markedly reduced from normal, even amongst 5-year survivors with the most favorable characteristics and treatment options.

    Full Text Available Abstract Introduction We report the case of a patient with a benign multicystic peritoneal mesothelioma and describe its appearance on computed tomography scans and ultrasonography, in correlation with gross clinical and pathological findings. Case presentation A 72-year-old Caucasian woman presented to our emergency department with acute abdomen signs and symptoms. A clinical examination revealed a painful palpable mass in her left abdomen. Abdominal ultrasonography and computed tomography demonstrated the presence of a large cystic mass in her left upper abdomen, adjacent to her left hemidiaphragm. The lower border of the mass extended to the upper margin of her pelvis. A complete resection of the lesion was performed. Pathological analysis showed a benign multicystic peritoneal mesothelioma. Conclusions Benign multicystic peritoneal mesothelioma is a rare lesion with a non-specific appearance on imaging. Its diagnosis always requires pathological analysis.

    About half the patients on peritoneal dialysis (PD) in China need to be assisted by family members or home assistants. We explored whether these patients have a higher risk for peritonitis and death compared with self-care PD patients. We prospectively followed 313 incident PD patients until death or censoring. This cohort was divided into assisted and self-care PD groups according to the independence of bag exchange. Data on baseline demographics, Charlson comorbidity index, biochemistry, and residual renal function were recorded during the first 3 - 6 months. The outcome variables were first episode of peritonitis and all-cause mortality. Of the 313 patients in this cohort study, 122 needed assistance in performing bag exchanges (86 from a family member, 36 from a home assistant); the remaining 191 patients did not need assistance. During a follow-up period averaging 44.5 months, 122 patients developed a first episode of peritonitis, and 135 patients died. Compared with patients having a family assistant, those with a home assistant had similar peritonitis-free and survival times, but a higher risk of mortality after adjustments for variables such as age, sex, Charlson comorbidity score, hemoglobin, serum albumin, and residual renal function. Furthermore, compared with self-care patients, assisted patients overall had a similar peritonitis-free time, but a higher risk of mortality, even after adjusting for covariates. Based on our single-center experience in China, we conclude that assisted PD is a good option for patients with poor self-care ability. This result provides evidence for recruiting patients who need assistance to PD programs in China.

    Abdominal tuberculosis usually involves a combination of organs (hepatosplenic, intestinal and/or genitourinary), lymph nodes (peritoneal and mesenteric) and peritoneum, mesentery and omentum. It preferentially affects immuno compromised patients (diabetic, cirrhotic, HIV-positive individuals). We present four cases in which abdominal tuberculosis involved only peritoneum, mesentery and omentum, with no radiological evidence of retroperitoneal lymph node or hepatosplenic disease. Exclusively peritoneal involvement is rare and the radiologic findings are nonspecific as they are also observed in other more common disorders. Despite this fact, tuberculosis should be included in the differential diagnosis, especially in immunocompromised patients. (Author) 8 refs

    Full Text Available Benign cystic mesothelioma (BCM is a rare benign disease that forms multicystic masses in the abdomen, pelvis, and retroperitoneum. It occurs predominantly in young to middle-aged women. The majority of cases were associated with a history of abdominal or pelvic operation, a history of endometriosis, and pelvic inflammatory disease. We present a unique case of BCM which is different to the previous cases. The patient was a 52-year-old man showing features of peritoneal carcinomatosis accompanied by ascites on abdominal computed tomography scans. We herein report a case of BCM misdiagnosed with peritoneal carcinomatosis.

    Full Text Available The prognosis of malignant peritoneal mesothelioma is extremely poor with a mean survival time of 12 months. The initial symptoms are poor and atypical. Because of its rare entity and little knowledge of its treatments, there are few reports of long-term survival. We encountered a very unique case with strong impression on radiological findings of malignant peritoneal methothelioma. We had misdiagnosed it because of the findings and because the time course was similar to that of ischemic colitis. The radiological findings on CT and enema disappeared within one week after antibiotic therapy.

    Full Text Available Acupuncture is an ancient and empirical therapeutic procedure known by its efficacy in the treatment of pain. However, the influence of acupuncture on inflammatory process is still poorly understood and additional research is needed. In this work, we investigated the mechanism of action of manual acupuncture on the inhibition of neutrophil migration to the peritoneal cavity induced by the inflammatory stimulus carrageenan in Wistar rats. Previous results from our laboratory showed that this anti-inflammatory effect is not due to endogenous corticoid release. Furthermore, the concentration of IL-1b, but not of TNF-alpha or IL-10 in the carrageenan-induced exudates was reduced in the acupuncture group. Further research will be needed to elucidate the mechanisms involved in the anti-inflammatory action of acupuncture as described here.A acupuntura é método terapêutico milenar reconhecido por sua eficácia no tratamento da dor, porém seu efeito sobre processos inflamatórios é ainda pouco conhecido e maiores estudos são necessários. Neste trabalho, é investigado o mecanismo de ação da acupuntura manual sobre a inibição na migração de neutrófilos para a cavidade peritoneal induzida por carragenina em ratos Wistar. Resultados prévios indicam que esse efeito antiinflamatório não depende de hormônios corticóides. Entretanto, as concentrações de IL-1b no exsudato induzido por carragenina foram reduzidas pelo tratamento com acupuntura. Por outro lado os níveis de TNF-alfa e IL-10 não foram afetados pelo tratamento. Mais pesquisas poderão elucidar os mecanismos envolvidos na ação antiinflamatória da acupuntura.

    Peritoneal membrane function can be assessed using the peritoneal equilibration test (PET) and similar tests, but these are almost always complicated to use, require a considerable amount of working time and their results cannot always be easily interpreted. Ionic conductivity is a measure of the ability of an electrolyte solution to conduct electricity. We tested the hypothesis that the ionic conductivity of peritoneal dialysate can be used to evaluate peritoneal membrane function in peritoneal dialysis patients. We measured the ionic conductivity and classic biochemical parameters of peritoneal dialysate in 69 patients during a modified PET and compared their ability to evaluate peritoneal membrane function and to diagnose ultrafiltration failure (UFF). Ionic conductivity was correlated well with classical parameters of peritoneal transport as glucose reabsorption of glucose (D/D0: r(2) = 0.62, P conductivity area under the receiver-operating characteristic curve was 0.91 (95% confidence interval: 0.81-0.96) with sensitivity of 1.00 and specificity of 0.84 at a cut-off value of 12.75 mS/cm. These findings indicate that the ionic conductivity of peritoneal dialysate can be used as a new screening tool to evaluate peritoneal membrane function. © The Author 2015.

    Chronic inflammation of the peritoneum causes peritoneal injury in patients on peritoneal dialysis. Intercellular adhesion molecule-1 and its circulating form, soluble intercellular adhesion molecule-1, play pivotal roles in inflammation. However, their role in peritoneal injury is unclear. We measured changes in intercellular adhesion molecule-1 expression in the peritoneum of a peritoneal injury model in rats. The associations between soluble intercellular adhesion molecule-1 levels in drained dialysate and the solute transport rate (D/P-Cr and D/D0-glucose) determined by the peritoneal equilibration test, and matrix metalloproteinase-2 levels in drained dialysate were investigated in 94 peritoneal drained dialysate samples. Intercellular adhesion molecule-1 expression was increased in the peritoneum of rats with peritoneal injury. Soluble intercellular adhesion molecule-1 levels in drained dialysate were significantly positively correlated with D/P-Cr (r = .51, p molecule-1expression is increased in the peritoneum of a peritoneal injury model in the rat, and soluble intercellular adhesion molecule-1 levels in drained dialysate are associated with peritoneal injury in patients on peritoneal dialysis. These results suggest that soluble intercellular adhesion molecule-1 could be a novel biomarker of peritoneal injury in patients on peritoneal dialysis.

    Peritoneal dialysis is a fully-contrasted alternative for the treatment of end-stage renal disease although it is not exempt of complications. Peritonitis and exit-site infections are among the most frequent complications found. Pleural effusion secondary to pleuroperitoneal communication (PPC) is a serious and uncommon complication in these patients. We present the case of a 50-year old man diagnosed of end-stage renal disease undergoing treatment with peritoneal dialysis who presented progressive dyspnea and right pleural effusion. The peritoneal scintigraphy with (99m)Tc-MAA makes it possible to confirm communication of intraperitoneal dialysis fluid to the pleural cavity. Copyright 2009 Elsevier España, S.L. y SEMNIM.

    The peritoneum is a frequent site of involvement by peritoneal tuberculosis. Generally, computed tomography appears to be the imaging modality of choice in the detection and assessment of abdominal tuberculosis. The computed tomography findings can help in the diagnosis of peritoneal tuberculosis, that is confirmed by a positive culture or hystologic analysis of biopsy obtained through laparoscopic examination. Peritoneal carcinomatosis is the main differential diagnosis. In this article we present the spectrum of tomographic manifestation of peritoneal tuberculosis and how we can differentiate it from peritoneal carcinomatosis. (author)

    Peritoneal dialysis (PD) limitation as renal replacement therapy is mostly due to peritonitis and complications. Formation and persistence of intra-abdominal loculations is often under-diagnosed. Encapsulated peritoneal sclerosis (EPS) is a life-threatening complication, but malnutrition, recurrent peritonitis and early membrane failure are insidious enemies that need to be emphasized. It is important to highlight the persistence of intra-abdominal fluid collection after clinical resolution of peritonitis in PD patients and to indicate a new medical management approach for an early diagnosis. During five years, we selected PD peritonitis cases followed by a six months interval free of infections. Ninety-seven subjects were followed at six months and one year after the first peritonitis. Tomography had been performed to patients presenting a positive inflammatory state without a specific infectious cause. Subjects presenting documented localized fluid collection (31 cases) were divided into: drug-treated group and those undergoing laparoscopy by a new surgery technique (seven patients); a comparison regarding the clinical state and biohumoral parameters was assessed in both groups. The prevalence of intra-abdominal loculation following an apparent resolved peritonitis was high (31.9%). The cases undergoing laparoscopy presented a better evolution - improved clinical status (p=0.001), higher hemoglobin values (p=0.06), significant lower doses of erythropoietin requirement (p=0.03), improved dialysis adequacy (p=0.005) and inflammatory state. In cases with confirmed fluid encapsulated loculation, an active attitude (screening imaging protocol and laparoscopic exploration) appears to be mandatory, decreasing the risk of EPS, a serious complication which pathology and treatment are incompletely understood.

    Comamonas testosteroni (C. testosteroni) has been rarely observed as an infectious agent in clinical practice. Few reports described its potential pathogenicity in bloodstream and abdominal infections. Here, we report our experience in the treatment of a C. testosteroni-associated peritonitis in a four-year-old girl receiving chronic peritoneal dialysis (PD). The organism was shown to be highly susceptible to appropriate antibiotic therapy. Infection responded promptly and the patient was managed conservatively without withdrawal from PD.

    Mechanical problems in continuous ambulatory peritoneal dialysis (CAPD) can result in ultrafiltration failure and disruption of CAPD therapy. The recently described tool of CT peritoneography with water-soluble contrast medium has the disadvantage of radiation and instillation of nephrotoxic substances. We report a child with a peritoneal leak diagnosed by MRI after instillation of a gadodiamide-dialysate mixture. This method provided good anatomical detail without radiation or nephrotoxic agents.

    Full Text Available The objective of the study was to identify the microbiological spectrum and drug-sensitivity pattern of peritonitis in patients on continuous ambulatory peritoneal dialysis. This was a prospective study done over a period of a year-and-a-half at a tertiary-care hospital in a hilly state of India. The effluent dialysate bags from 36 consecutive patients with peritonitis were studied. One hunderd ml dialysate fluid was processed under aseptic conditions by lysis centrifugation method. Microscopy and culture was done from the deposits for bacteriological, fungal, and mycobacterial isolates. They were identified by colony morphology and their biochemical reactions. Drug susceptibility testing was done by Kirby-Bauer disc diffusion method. In 36 dialysates, 33 (91.6% dialysates were culture-positive and in 3 (8.4%, the culture was negative. A total of 36 microorganisms were isolated in 33 cultures. Among the 36 microorganisms, 19 (52.8% isolates were gram-positive, 10 (27.8% were gram-negative, 5 (13.9% were fungi, and 2 (5.6% were mycobacterial isolates. All gram-positive organisms were sensitive to ampicillin, amoxi-clavulanic acid, cefazolin, clindamycin, and vancomycin. Neither a methicillin-resistant Staphylococci aureus nor a vancomycin-resistant Enterococcus was isolated in gram-positive isolates. Gram-negative organisms were sensitive to ciprofloxacin, ceftriaxone, ceftazidime, cefepime, gentamicin, piperacillin-tazobactam and imipenem. One of the gram-negative isolate was an extended spectrum beta-lactamase producer. Gram-positive peritonitis was more frequent than gram-negative peritonitis in our continuous ambulatory peritoneal dialysis patients. Mycobacterial causes were responsible for peritonitis in patients with culture-negative peritonitis which was not responding to the conventional antimicrobial therapy.

    To evaluate the ultrasonographic findings of the patients with sclerosing encapsulating peritonitis (SEP). Thirteen patients with surgically confirmed sclerosing encapsulating peritonitis were involved in this study. Because of intestinal obstruction, all patients had received operations. Among 13 patients, 12 cases had continuous ambulatory peritoneal dialysis (CAPD) for 2 months-12 years and 4 months from (mean; 6 years and 10 months), owing to chronic renal failure and one patient had an operation due to variceal bleeding caused by liver cirrhosis. On ultrasonographic examination, all patients showed loculated ascites which were large (n=7) or small (n=6) in amount with multiple separations. The small bowel loops were tethered posteriorly perisaltic movement and covered with the thick membrane. The ultrasonographic of findings of sclerosing encapsulating peritonitis were posteriorly tethered small bowels covered with a thick membrane and loculated ascites with multiple septa. Ultrasonographic examination can detect the thin membrane covering the small bowel loops in the early phase of the disease, therefore ultrasonography would be a helpful modality to diagnose SEP early.

    The purpose of the study was to evaluate the non-infectious complications of continuous ambulatory peritoneal dialysis (CAPD) using peritoneal computed tomography (PCT). Twenty symptomatic patients were included in the study. Initially 2000 ml of dialysate fluid was infused into the peritoneal cavity and standard peritoneal computed cavity and standard peritoneal computed tomography (SPCT) serial scans with 10 mm thickness were performed from the mid-thoracic region to the genital organs. Afterwards, 100 ml of non-ionic contrast material containing 300 mg/ml iodine was injected through the catheter and was distributed homogeneously in the intra-abdominal dialysate fluid by changing the positions of the patients; after waiting for 2-4 h, the CT scan was repeated as peritoneal contrast computed tomography (PCCT). In patients (n = 20) both SPCT and PCCT revealed 90 % (n = 18) pathological findings. But PCCT showed 60 % (n = 12) additional pathological findings. We believe that PCT is beneficial for evaluation of non-infectious complications of CAPD. But PCCT is superior to SPCT in evaluating non-infectious complications encountered in patients on CAPD treatment. (author)

    Can we identify modifiable risk factors for peritonitis in patients undergoing peritoneal dialysis (PD)? We aimed to determine whether housing standard, PD exchange technique or patient motivation might be modifiable risks for peritonitis. We also explored the relationship between lack of motivation and depression. Nurse home visits assessed PD exchange technique, environment and patient motivation. Motivation scores were correlated separately with an Apathy Evaluation Score and a depression score using PHQ-9 questionnaires. Home hygiene, exchange technique and motivation were above average in 53%, 56% and 60%, respectively in 104 patients undergoing PD. After 15 months, 25.9% patients developed peritonitis but nurses' ratings of homes and exchange techniques were not predictive. Low patient motivation was predictive. Patients rated to have above or below median motivation had significantly different Apathy Scores (p = 0.0002). Unmotivated depressed patients were significantly more likely to develop peritonitis compared to motivated depressed patients. Lack of motivation predicted peritonitis particularly if associated with depression.

    2013-01-01

    Background: In patients who were referred to the emergency department (ED) with abdominal pain, it is crucial to determine the presence of peritonism to allow for appropriate handling and subsequent referral to stationary departments. We aimed to assess the incidence of perceived peritonism...... to have signs indicative of peritonism, and 90% were admitted to the Department of Surgery (DS). Also, 24% of those patients with signs of peritonism and admission to the DS underwent surgical intervention in terms of laparotomy/laparoscopy. Five of the patients without peritonism underwent surgery...... with statistical significance were found regarding a stay in the emergency room (ER) or ordered imaging from the ER. Conclusion: Peritonism was a common finding in our setting. Peritonism did not require more acute surgery or imaging. The duration of the patient's stay in the ER was not influenced by a finding...

    Full Text Available A 52-year-old man undergoing continuous ambulatory peritoneal dialysis presented with two consecutive episodes of peritonitis caused by unusual organisms, namely, Brevibacterium and Pantoea agglomerans. The patient was successfully treated with a 2-week course of cefazolin and ceftazidime for the Brevibacterium-associated peritonitis, and a 3-week course of gentamicin for the P. agglomerans-associated peritonitis. Although these environmental organisms are rarely responsible for human infection, the number of reported cases of human infection by these unusual organisms has increased. This report emphasizes the potential for infection by environmental organisms in patients undergoing peritoneal dialysis.

    ♦ Chronic renal failure and aging are suggested as risk factors for cognitive impairment (CI). We studied the prevalence of CI among peritoneal dialysis (PD) patients using Montreal Cognitive Assessment (MoCA), its impact on PD-related peritonitis in the first year, and the potential role of assisted PD. ♦ One hundred fourteen patients were newly started on PD between February 2011 and July 2013. Montreal Cognitive Assessment was performed in the absence of acute illness. Data on patient characteristics including demographics, comorbidities, blood parameters, dialysis adequacy, presence of helpers, medications, and the number PD-related infections were collected. ♦ The age of studied patients was 59±15.0 years, and 47% were female. The prevalence of CI was 28.9%. Patients older than 65 years old (odds ratio [OR] 4.88, confidence interval [CI] 1.79 - 13.28 p = 0.002) and with an education of primary level or below (OR 4.08, CI 1.30 - 12.81, p = 0.016) were independent risk factors for CI in multivariate analysis. Patients with PD-related peritonitis were significantly older (p peritonitis among self-care PD patients (OR 2.20, CI 0.65 - 7.44, p = 0.20). When we compared patients with MoCA-defined CI receiving self-care and assisted PD, there were no statistically significant differences between the 2 groups in terms of age, MoCA scores, or comorbidities. There were also no statistically significant differences in 1-year outcome of PD-related peritonitis rates or exit-site infections. ♦ Cognitive impairment is common among local PD patients. Even with CI, peritonitis rate in self-care PD with adequate training is similar to CI patients on assisted PD. Copyright © 2016 International Society for Peritoneal Dialysis.

    Peritonitis is one of the major comorbidities of peritoneal dialysis (PD) patients. The aim of this study was to concentrate on potential risk factors, including more recently studied ones among the classical ones for peritonitis, in PD patients. We analysed 109 patients (F/M = 42/67) followed up at least for 3 months in a single centre, a tertiary referral hospital for 360.1 patient years. In the study which is designed as a retrospective cohort study, demographic characteristics, conditions for choosing PD, type of PD treatment, some chemical tests and peritonitis episodes were recorded from the files of the patients. The rate of peritonitis was found to be 0.22 episode/patient year and 22 (20.18%) of the patients had more than one episode. Twenty seven (24.8%) of the patients were allocated to PD due to obligatory reasons. According to multiple regression analysis, the associated factors were found to be PD allocation type (obligatory versus voluntary) (p = 0.04; RR = 2.6), serum albumin level (p = 0.05; RR = 1.2), and anti-hepatitis C Virus Antibody positivity (p = 0.03; RR = 1.6). Frequency of female patients were significantly higher in the group who had multiple episodes (p = 0.01). Obligatory referral which can be an indication of loss of motivation for peritoneal dialysis procedures, is thought to be a strong risk factor for peritonitis in PD patients and should be further studied. Patients with multiple episodes had a higher frequency of obligatory referral as expected and additionally, they were higher in number of females when compared to the ones with single episode.

    Peritoneal dialysis (PD) exchange procedure is complex. Patients with cognitive impairment (CI) may require assistance. We studied the prevalence of CI among PD patients, its impact on PD-related peritonitis and the outcome of assisted PD. Cantonese version of Mini-Mental State examination (CMMSE) was performed in 151 patients newly started on PD. Data on patient characteristics including demographics, co-morbidities, blood parameters, medications, and number of PD-related peritonitis in the first 6 months were collected. 151 subjects were recruited. The age of studied patients was 60 ± 15.0 years, and 45% were female. The prevalence of CI was 13.9% using education-adjusted cut-off of CMMSE. Patients older than 65-year-old, female, and lower education level were independent risk factors for CI (OR 9.27 p = 0.001, OR 14.84 p = 0.005, and OR 6.10 p = 0.009, respectively). Age greater than 65-year old is an independent risk factor for PD-related peritonitis but CI was not. Patients requiring assisted PD were of older age (p self-care PD patients, assisted PD patients did not have higher rates exit site infection (p = 0.30) but had a trend of higher PD peritonitis (p = 0.07). CI is common among local PD patients. Overall, CI could not be identified as an independent risk factor for PD peritonitis. There is a higher prevalence of CI among assisted PD patients but helpers may not completely eliminate the risk of PD-related peritonitis.

    An evaluation of the characteristics of peritoneal solute and water transport is essential to assess the suitability of prescribing dialysis in patients suffering from chronic renal disease. There are currently a series of models to perform this evaluation. The peritoneal equilibration test (PET) evaluates the peritoneal transport capacity, classifying the patients into four transport categories: high, high-average, low-average, and low. The short PET enables the same evaluation to be made in only 2hours, and has been validated in paediatric patients. On the other hand, the MiniPET provides additional information by evaluating the free water transport capacity by the ultra-small pores, and the Accelerated Peritoneal Examination Time (APEX) evaluates the time when the glucose and urea equilibration curves cross, and has been proposed as the optimum dwell time to achieve adequate ultrafiltration. An analysis is presented on the current information on these diagnostic methods as regards free water transport via aquaporins, which could be an important tool in optimising solute and water transport in patients on chronic peritoneal dialysis, particularly as regards the cardiovascular prognosis.

    2010-01-01

    This case describes a prune-belly syndrome patient who had a kidney transplantation and was diagnosed with Encapsulating Peritoneal Sclerosis (EPS), a rare but potentially fatal condition, mostly associated with Peritoneal Dialysis (PD). The definition of EPS is based on the clinical findings linked to bowel obstruction and on the demonstration of peritoneal thickening. Surgical treatment is the only established basic treatment for the condition. Prune-belly syndrome is characterized by the triad of deficient abdominal musculature, urinary tract abnormality and cryptorchidism. Because it is often associated with end-stage renal disease, PD is essential in the treatment of patients with prune-belly syndrome. The aetiology of EPS follows a 'two-hit theory': the first 'hit' is peritoneal deterioration, caused by long-time exposure to PD. This causes peritoneal disruption which predisposes the patient to a second hit. In our patient, PD discontinuation and renal transplantation are possible 'second hits' that triggered the development of EPS. This case of prune-belly syndrome has all the necessary elements for the development of EPS, and we felt we should report it as the peroperative diagnosis was unexpected.

    Peritoneal dialysis (PD) patients have equivalent or slightly better kidney transplant outcomes when compared to hemodialysis (HD) patients. However, given the risk for postoperative infection, we sought to determine the risk factors for PD catheter-associated infections for patients who do not have the PD catheter removed at the time of engraftment. Demographic and outcomes data were collected from 313 sequential PD patients who underwent kidney transplant from 2000 to 2015. Risk factors for postoperative peritonitis were analyzed using logistical regression. Of 329 patients with PD catheters at transplant, 16 PD catheters were removed at engraftment. Of the remaining 313 patients, 8.9% suffered post-transplant peritonitis. On univariate analysis, patients with peritonitis were significantly more likely to have used the PD catheter or HD within 6 weeks after transplant. Multivariate analysis had similar findings, with increased risk for those using the PD catheter after transplant, with a trend for those who underwent HD only within 6 weeks of transplant. These results suggest that delayed graft function requiring any type of dialysis is associated with increased post-transplant peritonitis risk. © 2018 John Wiley & Sons A/S.

    Assessment of peritoneal permeability is necessary for successful management of end-stage renal disease (ESRD) patients by continuous ambulatory peritoneal dialysis (CAPD). The objective of this study was to develop an alternative method of assessing the peritoneal permeability and to compare this method with the conventional method, the peritoneal equilibrium test, first described by Twardowski in 1987. Twenty patients undergoing regular CAPD were included in this study. Before starting the peritoneal dialysis, 370 MBq (10 mCi) technetium-99m diethylene triamine penta-acetic acid ({sup 99m}Tc-DTPA) was injected intravenously. A standard dose of the same quantity was kept and used later for calculations. At the end of 4 h, a dialysate fluid sample (1 ml) was collected and the total dialysis effluent fluid volume was measured. Excretion of {sup 99m}Tc-DTPA into the dialysate fluid as a percentage of the injected dose was calculated. Simultaneously, standard peritoneal equilibrium test values were recorded for comparison. Peritoneal excretion of {sup 99m}Tc-DTPA ranged from 8% to 25% of the injected dose, depending on the peritoneal membrane permeability. When the results were compared with the conventional method, a good correlation (r=0.79) was found. This innovative radionuclide technique is a simple and convenient method to assess the peritoneal membrane permeability and can be used as an alternative to the peritoneal equilibrium test, which is very cumbersome and associated with many limitations.

    Peritoneal dialysis is the most common modality for home dialysis and to ensure patients have access to dialysis at home, training programs have to ensure that the fellows attain clinical competency in the care of such patients. The limited data available however are sobering; about 10 years ago, 44% of nephrologists reported that they did not feel competent in the care of patients undergoing peritoneal dialysis. There are recognizable challenges in ensuring clinical competency of trainees that may need creative solutions. It is important for training program directors to evaluate the state of training at their institution, identify their unique barriers, and work to overcome them in the interest of ensuring that fellows are trained in all aspects of nephrology. © 2018 Wiley Periodicals, Inc.

    Worldwide, there is a steady incident rate of patients with end-stage kidney disease (ESKD) who require renal replacement therapy. Of these patients, approximately one-third have an "unplanned" or "urgent" start to dialysis. This can be a very challenging situation where patients have either not had adequate time for education and decision making regarding dialysis modality and appropriate dialysis access, or a decision was made and plans were altered due to unforeseen circumstances. Despite such unplanned starts, clinicians must still consider the patient's ESKD "life-plan", which includes the best initial dialysis modality and access to suit the patient's individual goals and their medical, social, logistic, and facility circumstances. This paper will discuss the considerations of peritoneal dialysis and a peritoneal dialysis catheter access and hemodialysis and central venous catheter access in patients who require an urgent start to dialysis.

    The mean age of patients with end-stage renal disease increases steadily. The elderly on dialysis have significant comorbidity and require extra attention to meet their dialysis, dietary, and social needs, and some may need to be treated at a long-term care facility such as a nursing home (NH). Providing dialysis and caring for elderly patients in a nursing home (NH) presents a number of challenges. Few data are available in the literature about elderly patients on peritoneal dialysis (PD) in an NH. This paper describes our experience of starting and maintaining a peritoneal dialysis program in three community-based nursing homes. During the period 2004-2008, after the nursing home personnel had received appropriate training, we established a PD program in three community-based nursing homes and admitted 38 patients on peritoneal dialysis. We educated 112 NH staff over the three-year period. Mean age of the patients at entry was 77.3 + or - 8.5(18.4%) were male. The main causes of end-stage renal disease were diabetes mellitus (DM) 21 (55.8%) and hypertension 13 (34.2%). Comorbid conditions included DM (27, 71.1%), hypertension (26, 68.4%), coronary artery disease (18.5%), chronic heart failure (11, 28.9%), cerebrovascular event (12, 31.6%), and cancer(3, 7.9%). The average total time on chronic peritoneal dialysis was 36.5 + or - 29.8 months, (median 31, range: 1-110 months) of which the average time in the NH program, as of the time of this report, was 18.4 + or - 13.1 months (median 15.5, range: 1-45 months). During the study period, 16 (42.1%) of the patients died, 2 (5.3%) transferred to HD, 2 (5.3%) stopped treatment, and 18 (47.4%) are still in the program. Actuarial patient survival from entry into the NH program was 89.5% at six months, 60.5% at 12 months, 39.5% at 24 months and 13.2% at 36 months. Patient survival from initiation of chronic dialysis was 89.5% at six months, 76.3% at 12 months, 63.1% at 24 months, and 39.5% at 36 months. We observed 28

    Mesothelioma are infrequently encountered tumors that aries from the surface of any mesothelial lined body cavity. They are found most often in the pleural cavity, less frequently in the peritoneal cavity, and much less frequently in the pericardial cavity or arising from the tunica vaginalis. Tumors are most malignant and usually are detected late in their course when they begin to interfere with organ function. Most noninvasive diagnostic efforts are not helpful. The radiographic appearance is nonspecific and so, diagnosis is commonly made by laparoscopy and laparotomy. We experienced 4 cases of 2 malignant and 2 benign peritoneal mesothelioma which were no evidence of asbestose exposure. And, we believe that one case of malignant mesothelioma may be a consequence of prior radiation therapy

    Insulin resistance has been associated with cardiovascular disease in peritoneal dialysis patients. Few studies have addressed the impact of fast transport status or dialysis prescription on insulin resistance. The aim of this study was to test whether insulin resistance is associated with obesity parameters, peritoneal transport rate, and glucose absorption. Insulin resistance was evaluated with homeostasis model assessment method (HOMA-IR), additionally corrected by adiponectin (HOMA-AD). Enrolled patients were prevalent nondiabetics attending at Santo António Hospital Peritoneal Dialysis Unit, who were free of hospitalization or infectious events in the previous 3 months (51 patients aged 50.4 ± 15.9 years, 59% women). Leptin, adiponectin, insulin-like growth factor-binding protein 1 (IGFBP-1), and daily glucose absorption were also measured. Lean tissue index, fat tissue index (FTI), and relative fat mass (rel.FM) were assessed using multifrequency bioimpedance. Patients were categorized according to dialysate to plasma creatinine ratio at 4 hours, 3.86% peritoneal equilibration test, and obesity parameters. Obesity was present in 49% of patients according to rel.FM. HOMA-IR correlated better with FTI than with body mass index. Significant correlations were found in obese, but not in nonobese patients, between HOMA-IR and leptin, leptin/adiponectin ratio (LAR), and IGFBP-1. HOMA-IR correlated with HOMA-AD, but did not correlate with glucose absorption or transport rate. There were no significant differences in insulin resistance indices, glucose absorption, and body composition parameters between fast and nonfast transporters. A total of 18 patients (35.3%) who had insulin resistance presented with higher LAR and rel.FM (7.3 [12.3, interquartile range] versus 0.7 [1.4, interquartile range], Pinsulin resistance. FTI and LAR were independent correlates of HOMA-IR in multivariate analysis adjusted for glucose absorption and small-solute transport (r=0

    Sclerosing encapsulating peritonitis is a rare and frequently severe entity characterized by total or partial involvement of small bowel loops by a membrane of fibrous tissue. The disease presents with nonspecific clinical features of intestinal obstruction, requiring precise imaging diagnosis to guide the treatment. The present report emphasizes the importance of computed tomography in the diagnosis of this condition and its confirmation by surgical correlation. (author)

    Purpose: To evaluate the ultrasonographic and CT findings of tuberculous peritonitis. Material and Methods: Ultrasonographic and CT findings of 11 patients with the ascitic type of tuberculous peritonitis were reviewed. Results: All patients had ascites, and ultrasonography (US) demonstrated fine complete and incomplete mobile septations in 10 patients. In 5 of them, the ascites had a lattice-like appearance. Diffuse regular peritoneal thickening was detected in all patients by CT and in 10 patients by US. CT demonstrated infiltration of the greater omentum in 9 patients, whereas US showed omental thickening in only 5 patients. Conclusion: Peritoneal and omental thickening detected by CT and ascites with fine, mobile septations shown by US strongly suggest the ascitic type of tuberculous peritonitis. The 2 imaging modalities should be used together for accurate diagnosis of tuberculous peritonitis. (orig.).

    Methods have been developed to distinguish subpopulations of murine peritoneal cells, and these were applied to the measurement of early changes in peritoneal cells after irradiation. The ratio of the two major subpopulations in the peritoneal fluid, lymphocytes and macrophages, was measured rapidly by means of cell volume distribution analysis as well as by hypotonic propidium iodide (PI) staining. After irradiation, dose and time dependent changes were noted in the cell volume distributions: a rapid loss of peritoneal lymphocytes, and an increase in the mean cell volume of macrophages. The hypotonic PI staining characteristics of the peritoneal cells showed two or three distinctive G 1 peaks. The ratio of the areas of these peaks was also found to be dependent of the radiation dose and the time after irradiation. These results demonstrate that these two parameters may be used to monitor changes induced by irradiation (biological dosimetry), and to sort different peritoneal subpopulations

    Renal replacement therapy is designed to treat uremic symptoms and correct hypervolemia. We hypothesized that starting peritoneal dialysis (PD) should reduce overhydration, and we measured body composition and hydration status using bioimpedance in PD patients prior to training and then at the first assessment of peritoneal membrane function. We studied 100 consecutive patients with a planned start to PD, without peritoneal infections or mechanical catheter problems, mean age 54.7 ± 17.1 years, 57% male and 25% diabetic. Extracellular water (ECW) overhydration increased from -0.06 (-1.21 to 0.97) L to 0.96 (0.50 to 3.01) L, p peritoneal protein transport (β 1.84, p peritoneal membrane function becomes available.

    Endometriosis is considered to be an inflammatory disease, and macrophages are the most numerous immune cells in endometriotic lesions. However, the mechanisms underlying the elevation of macrophages and their role in the pathogenesis and manifestations of endometriosis still remain unclear. The number of macrophages stained for CD68 in endometriotic lesions (n = 24) and in peritoneum distant from the lesions (n = 14) from women with endometriosis was compared with the number of macrophages in normal peritoneum from women without endometriosis (n = 18). Peritoneal lesions were also double-stained for CD68 and protein gene product 9.5 to study the relationship between macrophages and nerve fibres. The densities of macrophages in peritoneal endometriotic lesions and unaffected peritoneum from women with endometriosis were both significantly higher than that in normal peritoneum from women without endometriosis (P peritoneal lesions from women with endometriosis compared with normal peritoneum from women without endometriosis. These cells may well play roles in the growth and development of endometriotic lesions and in the generation of pain through interaction with nerve fibres.

    Histologic subtype is recognized as a prognostic factor in malignant pleural mesothelioma. Specifically, epithelial morphology is associated with a better prognosis than other subtypes, and the same association is observed in peritoneal malignant mesothelioma. Recently, prognostic differences based on morphologic subtypes of epithelial peritoneal malignant mesothelioma were reported. Herein, we report the interobserver variability across four pathologists at three institutions. The authors independently reviewed 67 cases of malignant peritoneal epithelioid mesotheliomas and subclassified them according to their epithelial subtype: papillary, tubulopapillary, trabecular, micropapillary, solid and/or pleomorphic. The cases were also evaluated by each author for several other histopathologic parameters including depth of invasion, nuclear grade, lymphocytic host response, mitotic count/index, presence of lymphovascular invasion, and stromal desmoplasia. The interobserver agreement for histopathologic parameters was highest for mitotic rate (κ=0.36) and primary epithelial subtype (κ=0.32). The interobserver variability for solid subtype pattern was moderate (κ=0.49). We found that the interobserver variability for most histopathologic parameters is poor. Copyright © 2017 Elsevier Inc.

    The evolution of home dialysis marked the main steps in the progress of renal replacement therapy. From the origins when home hemodialysis was often the only alternative to death, to the advent and widespread use of peritoneal dialysis, the dream of kidney transplant as a solution to all problems (at least in the young), and ultimately the profound social and organizational changes that have led to a drastic reduction of home hemodialysis, we arrive at the present with the rediscovery of the clinical, rehabilitative and economic advantages of home dialysis. Seven experts from five different centers with different expertise in home dialysis report their opinions on the future of home dialysis in a ''noncontroversial controversy''. Beyond the sterile competition between peritoneal dialysis and home hemodialysis, the shared opinion is that the two methods may complement each other, allowing a tailored treatment for each patient and a tailored organization in each setting. The organizational solutions are many; the authors underline the importance of longer survival and better rehabilitation, and the ethical need of offering each patient a choice among all available treatments. Add to this the importance of dedicated educational programs targeted to physicians, nurses and patients alike and focused on self-care and patient empowerment. A new generation of dialysis machines, easier technical solutions, and financial incentives may strengthen motivations and simplify problems; all these elements may in the near future be combined in a joint effort to increase peritoneal dialysis and revive home hemodialysis in Italy.

    Full Text Available BACKGROUND: Peritonitis still presents an extremely common & dreaded problem in emergency surgery. Despite aggressive surgical techniques, the prognosis of peritonitis and intra - abdominal sepsis is very poor, especially when multiple organ failure develops. Therefore early objective & reliable classification of the severity of peritonitis and intra - abdominal sepsis is needed not only to predict prognosis & to select patients for these aggressive surgical techniques but also to evaluate & compare the results of different treatment regimens. So, in this prospective st udy of 60 cases of peritonitis, the reliability of the Mannheim peritonitis index is assessed & its predictive power evaluated. MATERIALS & METHOD S : This prospective study was carried out in the department of surgery, GMCH, Udaipur from June 2014 to June 2 015 after taking the permission from institutional ethics committee. Patients from both sexes of various age groups having peritonitis of varied aetiology & who had undergone laparotomy were taken. A detailed history, thorough clinical examination & necess ary investigations were performed in e ach case according to planned p r o forma. After resuscitation laparotomy was done & operative findings were noted carefully and a proper note on the progress of each patient was maintained and any complications encounter ed were noted. So, early classification of patients presenting with peritonitis by means of objective scoring system was done to select patients for aggressive surgery & overall morbidity & mortality were analyzed. RESULTS: Total 60 patients of peritonitis were examined and common causes were peptic (61.6%, typhoid (21.6% and appendicular (8.3 %. Most common age group was found to be 21 to 50 years and male to female ratio was 4:1. Peritonitis was more common in patients involved in hard work and chronic Be di smokers (61.6%. About 46% of patients who presented for treatment within 48 hours of onset of illness

    Malignant mesothelioma of the peritoneum is a rare neoplasm with a rapidly fatal course. The tumour arises from the mesothelial cells lining the pleura and peritoneum or, rarely, in the pericardium or tunica vaginalis. This neoplasm is characterized by being difficult to diagnose, having a rapid evolution and a poor response to therapy. Mesothelioma is very glucose avid, and malignant pleural mesothelioma has been reported concerning the utility of F-18 FDG PET or PET/CT. But little has been known about the imaging finding of malignant peritoneal mesothelioma on F-18 FDG PET/CT. We report a case of malignant peritoneal mesothelioma mimicking peritoneal carcinomatosis of F-18 FDG PET/CT.

    Neonatal peritoneal calcifications usually suggest a diagnosis of meconium peritonitis, but in this case, a premature baby girl, peritoneal calcifications were caused by hydrometrocolpos secondary to imperforate hymen, a rare association. The patient presented with respiratory distress and ascites and demonstrated abdominal calcifications on plain film. Other radiographic work-up revealed hydrometrocolpos without evidence of gastrointestinal tract obstruction. The patient was diagnosed and treated for imperforate hymen; she was recovered fully.

    C-reactive protein (CRP) is a mediator of systemic inflammation. Peritoneal dialysis (PD) is known to cause peritoneal inflammation and fibrosis. We compare the degree of peritoneal inflammation and fibrosis in wild-type (WT) and CRP-transgenic (Tg) mice after PD treatment. WT (n = 7) and CRP-Tg (n = 10) C57BL/6 J mice (all male, 10-12 weeks old) were injected intra-peritoneally with 4.25% dextrose PD solution (3 mL/mouse) daily for 28 days, followed by a 2-h peritoneal equilibration test (PET). The mice were then killed. Parietal peritoneal and omental tissues were collected for the assessment of inflammation and fibrosis. After 28 days of PD treatment, CRP-Tg mice had higher dialysate-to-plasma (D/P) creatinine ratio than that of WT mice. Parietal peritoneum of the CRP-Tg mice was more cellular and thicker than that of the WT mice. CRP-Tg mice also had higher connective tissue growth factor (CTGF), intercellular adhesion molecule 1 (ICAM1) and tumor necrosis factor α (TNFα) RNA expressions as well as immunohistochemical staining in the parietal peritoneum than that of the WT mice. CRP-Tg mice have significantly more inflammation and fibrosis than WT mice after PD treatment. Our results suggest that CRP play a role in inflammation and fibrosis induced by PD. The implication of our results to human PD therapy needs further investigations. © 2016 Asian Pacific Society of Nephrology.

    Full Text Available Peritoneal fibrosis is a major complication in peritoneal dialysis (PD patients, which leads to dialysis discontinuation. Periostin, increased by transforming growth factor β1 (TGF-β1 stimulation, induces the expression of extracellular matrix (ECM genes. Aberrant periostin expression has been demonstrated to be associated with PD-related peritoneal fibrosis. Therefore, the effect of periostin inhibition by an aptamer-based inhibitor on peritoneal fibrosis was evaluated. In vitro, TGF-β1 treatment upregulated periostin, fibronectin, α-smooth muscle actin (α-SMA, and Snail expression and reduced E-cadherin expression in human peritoneal mesothelial cells (HPMCs. Periostin small interfering RNA (siRNA treatment ameliorated the TGF-β1-induced periostin, fibronectin, α-SMA, and Snail expression and restored E-cadherin expression in HPMCs. Similarly, the periostin-binding DNA aptamer (PA also attenuated fibronectin, α-SMA, and Snail upregulation and E-cadherin downregulation in TGF-β1-stimulated HPMCs. In mice treated with PD solution for 4 weeks, the expression of periostin, fibronectin, α-SMA, and Snail was significantly increased in the peritoneum, whereas E-cadherin expression was significantly decreased. The thickness of the submesothelial layer and the intensity of Masson’s trichrome staining in the PD group were significantly increased compared to the untreated group. These changes were significantly abrogated by the intraperitoneal administration of PA. These findings suggest that PA can be a potential therapeutic strategy for peritoneal fibrosis in PD patients.

    Full Text Available Objective: to study the diagnostic and prognostic values of the Mannheim peritoneal index (MPI in the development of postoperative local and systemic complications in patients with peritonitis. Materials and methods. The case histories of 92 patients with generalized peritonitis of varying etiology (other than pancreatogenic one were analyzed. The patients were retrospectively divided into 3 groups according to the outcomes and occurrence of postoperative local complications. The postoperative complications were classified by the procedure developed by A. L. Kostyuchenko et al. as local and systemic ones. When the patients had two signs or more of the systemic inflammatory response syndrome, they were stated to have systemic complications and to be diagnosed as having abdominal sepsis with the pattern of organ dysfunctions being described in accordance with the sepsis classification proposed by R. S. Bone et al. (1992. The number of organ dysfunctions was daily counted in each patient over time in the postoperative period. On the first postoperative day, MPI was calculated in scores for each patient; the mean MPI was estimated for all patient groups. The predictable mortality was calculated using the MPI plot. Results. All the patients with generalized peritonitis in the development of local postoperative complications were observed to have sepsis in the postoperative period, without developing local complication in 84.6% of the patients. A direct correlation was found between the MPI and the quantity of organ dysfunctions (r=0.6; p=0.001. In patients with local postoperative complications being developed, the MPI values were higher (p<0.05 than in those without them. The mortality rates that have been predicted by means of MPI (16.3% and actual (15.2% are actually in agreement. Conclusion. There is evidence for the diagnostic and prognostic values of MPI in the development of local and systemic postoperative complications in patients with

    The longevity of peritoneal dialysis (PD) is limited by high rates of technique failure, some of which stem from peritoneal membrane injury. 'Biocompatible' PD solutions have been developed to reduce damage to the peritoneal membrane. This review aimed to look at the benefits and harms of biocompatible PD solutions in comparison to standard PD solutions in patients receiving PD. We searched the Cochrane Renal Group's Specialised Register (28 February 2013), through contact with the Trials Search Co-ordinator using search terms relevant to this review. Studies contained in the Specialised Register are identified through search strategies specifically designed for CENTRAL, MEDLINE and EMBASE, and handsearching conference proceedings. All randomised controlled trials (RCTs) and quasi-RCTs in adults and children comparing the effects of biocompatible PD solutions (neutral pH, lactate-buffered, low glucose degradation product (GDP); neutral pH, bicarbonate (± lactate)-buffered, low GDP; glucose polymer (icodextrin)) in PD were included. Studies of amino acid-based PD solutions were excluded. Two authors extracted data on study quality and outcomes (including adverse effects). The authors contacted investigators to obtain missing information. Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratios (RR) and their 95% confidence intervals (CI) for categorical variables, and mean difference (MD) or standardised mean difference (SMD) and 95% CI for continuous variables.

    Molecular mechanisms of peritoneal dialysis (PD) ultrafiltration failure, peritoneal neo-angiogenesis, and fibrosis remain to be determined. We aimed to determine the role of heparin-binding EGF-like growth factor (HB-EGF) inhibition on angiogenesis of peritoneal membrane in a PD rat model. 32 male Wistar rats were assigned into (1) control group; (2) uremic non-PD group: subtotal nephrectomy-induced uremic rats without PD; (3) uremic rats subjected to PD: uremic rats that were dialyzed with Dianeal ® for 4 weeks; (4) CRM 197 group: dialyzed uremic rats were supplemented with CRM197, a specific HB-EGF inhibitor. Peritoneal transport function was examined by peritoneal equilibration test. Expression of HB-EGF and EGFR in peritoneal samples were examined by real-time PCR, immunohistochemical staining, and western blot. Progressive angiogenesis and fibrosis were observed in uremic PD rats, and there were associated with decreased net ultrafiltration (nUF), increased permeability of peritoneal membrane, and reduced expression of HB-EGF and EGFR protein and mRNA in uremic PD rats compared to uremic non-PD or control groups (both p CRM197 significantly induced peritoneal membrane permeability, decreased nUF, increased higher vessel density, and reduced pericyte count compared to that of uremic PD rats. The levels of HB-EGF and EGFR expression negatively correlated with vessel density in peritoneal membrane (both p < 0.001). PD therapy was associated with peritoneal angiogenesis, functional deterioration, and downregulation of HB-EGF/EGFR. Pharmacological inhibition of HB-EGF promoted PD-induced peritoneal angiogenesis and fibrosis and ultrafiltration decline, suggesting that HB-EGF downregulation contributes to peritoneal functional deterioration in the uremic PD rat model.

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

Despite its favourable safety profile, major complications can occur. Few studies have examined peritonitis following percutaneous retrograde gastrostomy in children. To identify potential risk factors and variables influencing the development and early diagnosis of peritonitis following percutaneous retrograde gastrostomy. We conducted a retrospective case-control study of children who developed peritonitis within 7 days of percutaneous retrograde gastrostomy between 2003 and 2012. From the 1,504 patients who underwent percutaneous retrograde gastrostomy, patients who developed peritonitis (group 1) were matched by closest date of procedure to those without peritonitis (group 2). Peritonitis was defined according to recognized clinical criteria. Demographic, clinical, procedural, management and outcomes data were collected. Thirty-eight of 1,504 children (2.5%; 95% confidence interval, 1.8-3.5) who underwent percutaneous retrograde gastrostomy developed peritonitis ≤7 days post procedure (group 1). Fever (89%), irritability (63%) and abdominal pain (55%) occurred on presentation of peritonitis. Group 1 patients were all treated with antibiotics; 41% underwent additional interventions: tube readjustments (8%), aspiration of pneumoperitoneum (23%), laparotomy (10%) and intensive care unit admission (10%). In group 1, enteral feeds started on average 3 days later and patients were discharged 5 days later than patients in group 2. There were two deaths not directly related to peritonitis. Neither age, gender, weight, underlying diagnoses nor operator was identified as a risk factor. Peritonitis following percutaneous retrograde gastrostomy in children occurs in approximately 2.5% of cases. No risk factors for its development were identified.

    To determine if the rate of peritoneal dialysis (PD)-related infections in our large Native population was higher than in non-Natives. Prospective study of PD-related infections, 1987 to 1993. Forty-eight Natives and 136 non-Natives were studied. Comparisons of infection rates were made as well as determinations of the effect of diabetes and of dialysis techniques on infection rate. The chance of remaining free of peritonitis was far lower at 6 and 12 months in Natives versus non-Natives, 40% versus 76% at 6 months, and 24% versus 54% at 12 months (p Natives only. Exit-site infection (ESI) was significantly higher in Natives versus non-Natives, 0.42 versus 0.19 episodes per patient year (p Native patients, whereas infections due to most other organisms were. The susceptibility to both peritonitis and exit-site infection is increased in Native Canadians compared to non-Natives. The nonprotective effect of the Y-line combined with increased peritonitis due to most organisms except Staph. epidermidis in Natives suggests that host factors could be important in these patients.

    Fibrin has classically been considered a defense mechanism of the peritoneal cavity. We have studied the role of purified fibrin in the pathogenesis of intraperitoneal infection. Implantation of 0.5% bovine fibrin clots containing 2 X 10(8) E. coli into the rat peritoneal cavity reduces the 24-hour mortality rate from 100% to 0% compared to bacteria in a similar volume of saline solution. However, the 10-day mortality rate with fibrin is 90%; 100% develop intraperitoneal abscesses. Animals receiving sterile clots lyse than over 1 to 2 weeks without abscess formation. As few as 10(2) E. coli per fibrin clot produce abscesses, but 10(7) or more are required to produce death; without fibrin less than 10(7) E. coli neither kill nor produce intraperitoneal infections. Both late death and abscess size with 2 X 10(8) E. coli are directly proportional to the fibrin clot size but not the concentration of fibrin in the clot. Operative debridement of the fibrin at 4 or 24 hours completely eliminates abscess formation in surviving animals. In vitro growth of E. coli is neither stimulated nor inhibited by fibrin or fibrinogen. Fibrin delays systemic sepsis, but the entrapped bacteria cannot be easily eliminated by normal intraperitoneal bactericidal mechanisms and abscess formation occurs. Thus radical peritoneal debridement or anticoagulation may reduce the septic complications of peritonitis.

    Full Text Available The dysfunction of the catheter in peritoneal dialysis (PD is a frequent compli-cation. However, perforation of organs are rare, particularly that of the urinary bladder. This re-quires an early diagnosis and prompt treatment of patients. We report here the case of a 38-year-old woman having end-stage renal disease due to autosomal-dominant polycystic kidney disease treated by PD since November 2000. Three years later, she was treated for Staphylococcal peritonitis. Four months later, she presented with a severe urge to urinate at the time of the fluid exchanges. The biochemical analysis of the fluid from the bladder showed that it was dialysis fluid. Injection of contrast through the catheter demonstrated the presence of a fistula between the bladder and the peritoneal cavity. She underwent cystoscopic closure of the fistulous tract and the PD catheter was removed. Subsequently, the patient was treated by hemodialysis. One month later, a second catheter was implanted surgically after confirming the closure of the fistula. Ten days later, she presented with pain at the catheter site and along the tunnel, which was found to be swollen along its track. The injection of contrast produced swelling of the subcutaneous tunnel but without extravasation of the dye. PD was withdrawn and the patient was put back on hemodialysis. Bladder fistula is a rare complication in PD and diagnosis should be suspected when patient complains of an urge to pass urine during the exchanges, which can be confirmed by contrast study showing presence of dye in the bladder. PD may be possible after the closure of the fistula, but recurrence may occur.

    Full Text Available Abstract Results of application of a new technology of intraoperative photodynamic therapy (IOFDT in patients with peritoneal mesothelioma developed at P. Herzen Moscow Oncology Research Institute are presented. The study included 8 patients. 3 patients underwent surgery in various amount: 1 – limited peritonectomy in the volume of tumor foci resection and resection of a large omentum, 1 – limited peritonectomy in the volume of tumor foci resection and atypical resection of the right lobe of the liver, 1 – only resection of the large omentum due to the fact that the tumor was located only in a large omentum and no signs of lesions of the parietal peritoneum was revealed by intraoperative revision. Surgical intervention in these patients was concluded by IOPDT. The remaining 5 patients underwent only IOPDT. After the treatment, two patients underwent additional courses of laparoscopic IOPDT. Of the 8 patients enrolled in the study, 4 died from the underlying disease, 1 from cardiovascular disease with recurrence of the disease, 1 from cardiovascular disease without signs of recurrence, 2 were monitored for 6 months and 146 months (12 years. Thus, in the group of patients with peritoneal mesothelioma, the maximum observation period was 146.44 months, the median survival was 48.4 months, the total specific 1-year survival was 85.7±13.2%, the three-year survival was 68.5±18.6%, the 5-year survival was 45.7 ± 22.4 %. The average life expectancy after treatment of patients with repeated courses of laparoscopic IOPDT was 87 months, without repeated courses – 35.8 months. Thus, life expectancy was higher in patients with repeated courses of laparoscopic IOPDT. Small sample size caused to the rarity of this pathology does not allow for statistically significant conclusions. However, the results of the study indicate the prospects of multi-course intraoperative photodynamic therapy in patients with peritoneal mesothelioma.

    Peritonitis remains a common complication of peritoneal dialysis. The aim of our study is to describe the mechanisms of antibiotic resistance in bacteria isolated during peritonitis in peritoneal dialysis, to determine whether antibiotic therapy proposed by the International Society for Peritoneal Dialysis (ISPD) is adapted to the mechanisms of resistance. All causative microorganisms of peritonitis, isolated in 106 dialysis patients and reported 170 episodes of peritonitis, during the study period (01/01/2005 to 31/12/2010) were reviewed. According to the usual classification, twelve groups of microorganism were created. An interpretive reading of antibiograms was performed in each group to identify resistance phenotypes. The species most frequently isolated are coagulase-negative staphylococci (n=73) of which 46 had PBP2a (penicillin-binding protein). Many Enterobacteriaceae were also isolated (n=45), they are susceptible to third generation cephalosporins with the exception of Enterobacteriaceae producing an extended spectrum β-lactamase (ESBL) or a cephalosporinase. Except for staphylococci, probabilistic antibiotic therapy recommended by the ISPD to treat peritonitis is effective. Indeed, many staphylococci producing a PBP2a, a first-generation cephalosporin cannot be administered in all cases. It is therefore necessary to identify patients with a strain of staphylococcus producing a PBP2a, it must be treated by vancomycin. Copyright © 2012 Association Société de néphrologie.

    Full Text Available Abstract Introduction Acute hydrothorax is an uncommon but a well-recognized complication of peritoneal dialysis. No single test is definitive for diagnosis. Although it is not a life-threatening condition, hydrothorax often requires abandonment of peritoneal dialysis. Delay in diagnosis can lead to worsening of the clinical status. Case Presentation A 33-year-old Caucasian woman with lupus, who was successfully treated with temporary peritoneal dialysis 17 years previously, presented with acute dyspnea and a right pleural effusion after recommencing peritoneal dialysis. Investigations eliminated infective, cardiac, and primary respiratory causes. Peritoneal dialysis-related hydrothorax was suggested by biochemistry, and a pleuroperitoneal leak was definitively confirmed by using a Tc-99 m DTPA (diethylene triamine penta-acetic acid scintigraphy scan. Subsequently, she underwent video-assisted thoracoscopy-guided talc pleurodesis and was able to return successfully to peritoneal dialysis. Conclusion Although our case is not the first report that describes the occurrence of acute hydrothorax in peritoneal dialysis, it is an important condition to recognize for the wider general medical community. Furthermore, this case demonstrates that peritoneal dialysis can be continued with a hydrothorax, provided the underlying cause can be corrected. We review the literature pertaining to the utility and reliability of different diagnostic approaches to hydrothorax.

    Full Text Available Peritoneal dialysis (PD frequently contributes to peritoneal damage which cannot be easily identified without invasive techniques, implying the urgent need for biomarkers and revealing mechanisms. Chronic glomerulonephritis (CGN is one of the leading causes of receiving dialysis treatment. Here, we attempted to analyze the peritoneal dialysate collected from CGN patients when they receive continuous ambulatory peritoneal dialysis (CAPD treatment for the first time and after a year to reveal the protein changes that resulted from PD. Proteins were displayed by two-dimensional gel electrophoresis (2DE. Altered gel spots were digested followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS analysis for protein identification. Eight proteins were found to have differential expression levels between two groups. Their differential expressions were validated by Western blots in other sets of peritoneal dialysates. Proteins identified with higher levels in the first-time dialysate suggested their dominant appearance in CGN patients, while those that showed higher levels in peritoneal dialysate collected after one year may result from initial peritoneal inflammation or changes in the permeability of the peritoneum to middle-sized proteins. All the identified proteins may provide a perceptiveness of peritoneal changes caused by PD and may function as potential biomarkers or drug targets.

    Full Text Available The presentation of disseminated peritoneal leiomyomatosis (DPL can be misleading. Herein, we present the case of a 42-year-old nulliparous female who had previously undergone a total hysterectomy and presented with an acute abdomen. A presumptive diagnosis of ovarian torsion was made based on the clinical findings and an ultrasonographic examination. A diagnostic laparoscopy was performed immediately. DPL was subsequently diagnosed based on an intra-operative frozen section during surgical exploration and the final histopathologic examination. This case illustrates an atypical presentation of DPL mimicking ovarian torsion.

    The main causes of death in patients undergoing dialysis are cardiovascular diseases. Their presence is related to the nutritional status of patients treated with peritoneal dialysis, and has a predicted value in this kind of patient. Long-term therapy entails unfavourable changes, from which a clinically significant complication is protein-energy malnutrition and intensification of inflammatory processes. The aim of the study was to assess the nutritional status of patients with chronic kidney disease treated with peritoneal dialysis based on anthropometric, biochemical parameters analysis, a survey, as well as the determination of changes in measured parameters occurring over time. The study involved 40 people undergoing peritoneal dialysis (PD) and 30 healthy people. For dialyzed patients testing material was collected twice, every 6 months. Proteins, albumins, prealbumins, C-reactive protein and glucose levels were measured. Anthropometric measurements included body height, body weight, triceps skinfold and subscapular skinfold thickness. Body mass index (BMI) value and exponent of tissue protein source were calculated. The examined patients completed the questionnaire, which included, among other factors, the daily intake of nutrients, and lifestyle information. During the 6 month observation of the PD group a stastically significant increase in the energy value of intake food and amount of calories intake from carbohydrates was found. Analysis of nutritional status dependent on the BMI showed that overweight and obese patients are characterized by higher concentrations of the C-reactive protein and glucose, as well as lower concentrations of prealbumin compared to patients with normal body weight. At the same time, the energy value of food and the amount of protein in the group with BMI > 25 were smaller than in the other groups. During the 6 month observation a decrease the concentration of prealbumin and an increase in C-reactive protein in BMI > 25 group

    Barium sulfate is universally used contrast media in gastrointestinal roentgenology, and spillage of barium into peritoneal cavity can occur. The references on effect of barium sulfate in the peritoneal cavity have been scattered and the results are varied. In 80 rats, body weight of 130 gm to 150 gm, sterile pure barium, sterile commercial barium, intestinal content, and mixed pure barium and intestinal content were experimentally injected into the peritoneal cavity. Consecutive weekly laparotomy and microscopic examination were done for 4 weeks. The results are as followings: 1. Mind inflammatory reaction and mild adhesion after sterile pure barium injection. 2. Mild inflammatory reaction and moderate adhesion after sterile commercial barium injection. 3. Acute peritonitis and abscess formation after intestinal content injection. 4. High mortality due to severe acute peritonitis, and severe adhesion in survivors after injection of both pure barium and intestinal content.

    The purpose of this study was to evaluate retrospectively the safety and effectiveness of radiologically placed tunneled peritoneal catheter in palliation of malignant ascites. Between July 2005 and June 2009, 41 tunneled peritoneal catheters were placed under ultrasonographic and fluoroscopic guidance in 40 patients (mean age, 55 years; 22 women) who had symptomatic malignant ascites. No procedure related mortality was observed. Major complication occurred in one patient (2.5%) in the form of serious bacterial peritonitis that necessitated catheter removal. Minor complications such as minor bacterial peritonitis, catheter dislodgement, tunnel infection, and catheter blockage occurred in 11 patients (27.5%). The mean duration of survival after catheter placement was 11.8 weeks. All patients expired of their primary malignancies in the follow-up. Radiologically placed tunneled peritoneal catheter is safe and effective in palliation of symptomatic malignant ascites.

    Ultrasonography was performed prospectively in 20 patients who were undergoing continuous ambullatory peritoneal dialysis for evaluation of complications. We examined the abdominal wall along the course of catheter and the peritoneal cavity with special attention to the dialysate distribution, dialysate echogenecity, thickness of the peritoneum small bowel distribution and the position of the catheter tip. Peritonitis was the most common complication (n=7); sonographic findings were small bowel adhesion (n=5) multiseptated ascites(n=1), peritoneal thickening(n=4), and tunnel infection(n=1) and exith site infection(n=1). Our initial experience suggests that ultrasonography is useful for diagnosis of complications and monitoring of patient during long term peritoneal dialysis

    Candida peritonitis is reported in people and is associated with significant morbidity and mortality compared with sterile or bacterial peritonitis. Recognized predisposing risk factors include peritoneal dialysis, hollow viscous organ perforation, abdominal surgery, inflamed intestinal mucosa, antimicrobial administration, and immunosuppression. In this report, we describe 5 cases of dogs with peritonitis complicated by Candida spp; 3 dogs with C albicans, one dog with C albicans and C glabrata, and one dog with C glabrata only. The 3 dogs with C albicans peritonitis presented with duodenal perforation due to NSAID therapy, intestinal resection and anastomosis following postspay-surgery dehiscence, and intestinal foreign body removal. The 2 dogs with C glabrata peritonitis had undergone cholecystectomy due to gall bladder rupture and dehiscence of intestinal biopsy removal sites following exploratory laparatomy. In all cases, initial diagnosis of fungal peritonitis was made via cytologic examination of peritoneal effusions, which revealed marked pyogranulomatous inflammation with numerous 3-8 μm oval, deeply basophilic yeast organisms with thin clear capsules noted within phagocytes and extracellularly. In addition, germ tube formation, hyphae, and pseudohyphae were rarely seen in some of the cases with pure C albicans. Identity of the organisms was determined by culture in all cases and confirmed by PCR in 3 cases. Candida spp. are commensals normally inhabiting the alimentary, the upper respiratory, and the lower urogenital tracts of mammals. They are opportunistic pathogens that can invade and colonize tissue when a patient is immune-compromised or there is disruption of the mucosal barrier. Candida peritonitis should be considered in patients with peritoneal contamination with gastrointestinal or biliary contents. © 2013 American Society for Veterinary Clinical Pathology.

    Maintenance peritoneal dialysis (PD) is the dialysis modality of choice for infants and young children. However, there are limited outcome data for those who undergo PD catheter insertion and initiate maintenance PD within the first year of life. Using data from the Children's Hospital Association's Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (ESRD) Collaborative (SCOPE), we examined peritonitis rates and patient survival in 156 infants from 29 North American pediatric dialysis centers who had a chronic PD catheter placed prior to their first birthday. In-hospital and overall annualized rates of peritonitis were 1.73 and 0.76 episodes per patient-year, respectively. Polycystic kidney disease was the most frequent renal diagnosis and pulmonary hypoplasia the most common co-morbidity in infants with peritonitis. Multivariable regression models demonstrated that nephrectomy at or prior to PD catheter placement and G-tube insertion after catheter placement were associated with a nearly sixfold and nearly threefold increased risk of peritonitis, respectively. Infants with peritonitis had longer initial hospital stays and lower overall survival (86.3 vs. 95.6%, respectively; P high and several risk factors associated with the development of peritonitis were identified. Given that peritonitis was associated with a longer duration of initial hospitalization and increased mortality, increased attention to the potentially modifiable risk factors for infection is needed.

    Peritonitis, which is one of the leading complications of peritoneal dialysis (PD) worldwide, severely affected morbidity and mortality of the PD patients. Although many efforts have been made to prevent PD-related peritonitis, it seems impossible to prevent it completely. Many causes have been reported to lead to peritonitis, and contamination during bag exchange is one of the important risk factors for peritonitis. Here, we introduce an operating vehicle, which we invented to provide a sterile and safe space for bag exchange. A single-center, retrospective, case-control study was undertaken to determine whether this operating vehicle has a protective role in preventing peritonitis. In total, 462 continuous ambulatory peritoneal dialysis patients were included in this study from October 2014 to March 2017. According to their personal will, these patients chose to use operating vehicle or traditional method during their bag exchange. The demographic, clinical and laboratory data of these patients in the two groups were collected, analyzed and compared. Of 462 patients with home dialysis, operating vehicle group consisted of 61 patients, and control group consisted of 401 patients. In the control group, over 677 patient-years, peritonitis occurred in 69 of 401 patients (17.2%), while in the operating vehicle group, over 60 patient-years, only 4 of 61 patients (6.6%) had episodes of peritonitis. The number of patients suffered from peritonitis was significantly decreased in the operating vehicle group (P = 0.034). Besides, there were a total of 99 episodes of peritonitis, and the rate was 1 episode every 7.2 patient-years in control group and 1 episode every 12 patient-years in the operating vehicle group. There was significant difference between the two groups (0.013). Positive dialysate cultures were obtained in majority of the peritonitis episodes (60.6%). Operating vehicle might help to reduce PD-related peritonitis by preventing contamination during bag

    Technical innovations in peritoneal dialysis (PD), now used widely for the long-term treatment of ESRD, have significantly reduced therapy-related complications, allowing patients to be maintained on PD for longer periods. Indeed, the survival rate for patients treated with PD is now equivalent to that with in-center hemodialysis. In parallel, changes in public policy have spurred an unprecedented expansion in the use of PD in many parts of the world. Meanwhile, our improved understanding of the molecular mechanisms involved in solute and water transport across the peritoneum and of the pathobiology of structural and functional changes in the peritoneum with long-term PD has provided new targets for improving efficiency and for intervention. As with hemodialysis, almost half of all deaths on PD occur because of cardiovascular events, and there is great interest in identifying modality-specific factors contributing to these events. Notably, tremendous progress has been made in developing interventions that substantially reduce the risk of PD-related peritonitis. Yet the gains have been unequal among individual centers, primarily because of unequal clinical application of knowledge gained from research. The work to date has further highlighted the areas in need of innovation as we continue to strive to improve the health and outcomes of patients treated with PD.

  19. Peritoneal Dialysis Tailored to Pediatric Needs

    C. P. Schmitt

    2011-01-01

    Full Text Available Consideration of specific pediatric aspects is essential to achieve adequate peritoneal dialysis (PD treatment in children. These are first of all the rapid growth, in particular during infancy and puberty, which must be accompanied by a positive calcium balance, and the age dependent changes in body composition. The high total body water content and the high ultrafiltration rates required in anuric infants for adequate nutrition predispose to overshooting convective sodium losses and severe hypotension. Tissue fragility and rapid increases in intraabdominal fat mass predispose to hernia and dialysate leaks. Peritoneal equilibration tests should repeatedly been performed to optimize individual dwell time. Intraperitoneal pressure measurements give an objective measure of intraperitoneal filling, which allow for an optimized dwell volume, that is, increased dialysis efficiency without increasing the risk of hernias, leaks, and retrofiltration. We present the concept of adapted PD, that is, the combination of short dwells with low fill volume to promote ultrafiltration and long dwells with a high fill volume to improve purification within one PD session. The use of PD solutions with low glucose degradation product content is recommended in children, but unfortunately still not feasible in many countries.

  20. Advances in the management of peritoneal mesothelioma

    Malignant peritoneal mesothelioma (PM) is an infrequent disease which has historically been associated with a poor prognosis. Given its long latency period and non-specific symptomatology, a diagnosis of PM can be suggested by occupational exposure history, but ultimately relies heavily on imaging and diagnostic biopsy. Early treatment options including palliative operative debulking, intraperitoneal chemotherapy, and systemic chemotherapy have marginally improved the natural course of the disease with median survival being approximately one year. The advent of cytoreduction (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has dramatically improved survival outcomes with wide median survival estimates between 2.5 to 9 years; these studies however remain largely heterogeneous, with differing study populations, tumor biology, and specific treatment regimens. More recent investigations have explored extent of cytoreduction, repeated operative intervention, and choice of chemotherapy but have been unable to offer definitive conclusions. CRS and HIPEC remain morbid procedures with complication rates ranging between 30% to 46% in larger series. Accordingly, an increasing interest in identifying molecular targets and developing targeted therapies is emerging. Among such novel targets is sphingosine kinase 1 (SphK1) which regulates the production of sphingosine-1-phosphate, a biologically active lipid implicated in various cancers including malignant mesothelioma. The known action of specific SphK inhibitors may warrant further exploration in peritoneal disease. PMID:25206274

Risk factors for the development of gastrointestinal complications in this patient population include: toxic effects of uremic toxins, frequent use of nonsteroidal anti-inflammatory drugs, Helicobacter pylori infection, angiodysplasia, increased intra-abdominal pressure, use of bioincompatible solution for peritoneal dialysis, increased glucose in solutions for peritoneal dialysis, secondary hyperparathyroidism (hypercalcemia, a disorder of lipid metabolism (hypertriglyceridemia, and the duration of peritoneal dialysis treatment. The most important non-infectious gastrointestinal complications in patients on peritoneal dialysis are: gastrointestinal bleeding, herniation and leaking of the dialysate from the abdomen (increased intra-abdominal pressure, impaired lung function (intra-abdominal hypertension, acute pancreatitis, and encapsulating sclerosis of the peritoneum. Intra-abdominal hypertension is defined as IAP ≥ 12 mmHg. Pouring the peritoneal dialysis solution leads to increased intra-abdominal pressure, which results in the development of hernias, pleuro-peritoneal dialysate leakage (hydrothorax, and restrictive pulmonary dysfunction. Risk factors for the development of acute pancreatitis in this patient population include: uraemia, secondary hyperparathyroidism with hypercalcemia, hypertriglyceridemia, features of the peritoneal dialysis solution (osmolarity, acidity, glucose, chemical irritation, and calcium in the solution for peritoneal dialysis lead to “local hypercalcemia”, toxic substances from the dialysate, the bags and tubing, and peritonitis and treatment of peritonitis with antibiotics and anticoagulants. Encapsulating sclerosis of the peritoneum is rare and is the most serious complication of long-term peritoneal dialysis. It is characterized by thickening of the peritoneum, including cancer, and signs and symptoms of obstructive ileus

    Severe stages of acute, colonic diverticulitis can progress into intestinal perforations with peritonitis. In such cases, urgent treatment is needed, and Hartmann's procedure is the standard treatment for cases with fecal peritonitis. Peritoneal lavage may be an alternative to resection for acute...... diverticulitis with purulent peritonitis, but ongoing randomized trials are awaited to clarify this....

    We report here an unusual presentation of peritoneal endometriosis with smooth muscle metaplasia as multiple protruding masses on the lateral pelvic wall. Smooth muscle metaplasia is a common finding in rectovaginal endometriosis, whereas in peritoneal endometriosis, smooth muscle metaplasia is uncommon and its nodular presentation on the pelvic wall is even rarer. To the best of our knowledge, this is the first case of nodular smooth muscle metaplasia occurring in peritoneal endometriosis. As observed in this case, when performing laparoscopic surgery in order to excise malignant tumors of intra-abdominal or pelvic organs, it can be difficult for surgeons to distinguish the metastatic tumors from benign nodular pelvic wall lesions, including endometriosis, based on the gross findings only. Therefore, an intraoperative frozen section biopsy of the pelvic wall nodules should be performed to evaluate the peritoneal involvement by malignant tumors. Moreover, this report implies that peritoneal endometriosis, as well as rectovaginal endometriosis, can clinically present as nodular lesions if obvious smooth muscle metaplasia is present. The pathological investigation of smooth muscle cells in peritoneal lesions can contribute not only to the precise diagnosis but also to the structure and function of smooth muscle cells and related cells involved in the histogenesis of peritoneal endometriosis.

    The continuous quality improvement approach in peritoneal dialysis practice necessitates definition of the factors and the procedures that may possibly be contributing to the final success of peritoneal dialysis. The philosophy of continuous quality improvement uses the Plan, Do, Check, Act (PDCA) cycle. To improve the procedures used during peritoneal dialysis, the first step is to create a plan, then to carry out the plan, to check it, and after the collection of satisfactory information, to execute the chosen improvement action. Several studies have identified the most frequent causes of transfer from PD to HD as infection, catheter problems, inadequate dialysis, and psychosocial factors, among others. According to training guidelines from the International Society for Peritoneal Dialysis, seven points are of major importance to decrease infection risks: exit-site care, catheter placement, antibiotic prophylaxis for procedures, prevention of bowel-source peritonitis, prevention of fungal peritonitis, and connection methods. On the other hand, other factors such as hypoalbuminemia, depression, and obesity should also be taken into consideration for better technique survival in peritoneal dialysis patients.

    Management of chronic uremia in elderly patients presents several clinic and organizational difficulties. Hemodialysis (HD) and chronic peritoneal dialysis (CPD) are both available for the elderly, and the choice depends on the individual, clinical and familial conditions. Several reports have compared the outcomes for older patients treated by HD or peritoneal dialysis, with those for younger or older patients undergoing peritoneal dialysis. CPD is a successful dialysis option for elderly patients, in both patient and technique survival terms. All nutritional parameters are of pivotal importance. Several barriers, such as medical and social factors, physician bias, late referral and education irrespective of the needs of older patients, influence the choice of CPD. The development of assisted peritoneal dialysis, using community-based nurses or health care assistants, can overcome some of the barriers and enable frail older patients to have home-based dialysis treatment. Increasing age is associated with higher peritonitis rates among patients who started CPD in the 1990s, while age is not associated with peritonitis in more recent CPD cohorts, and no greater frequency of adverse outcomes of peritonitis has been seen among those who began CPD after the year 2000. In elderly dialysis patients, the management of quality of life (QOL) is important as well as adequacy of dialysis, nutritional status and survival rate. To obtain a good standard of QOL, it is essential to select carers who are properly educated and who can access an adequate support system, both physical and psychological, to help them cope with their burden.

    Continuous ambulatory peritoneal dialysis has become an increasingly popular modality of renal replacement therapy. Laparoscopic placement of peritoneal dialysis catheters may help overcome previous barriers to peritoneal dialysis, such as previous abdominal surgical procedures or the presence of hernias, without incurring substantially greater risks. We performed a retrospective review of 120 consecutive patients who underwent attempted laparoscopic peritoneal dialysis catheter placement between July 2009 and June 2014 by a single surgeon. Patient and catheter characteristics and outcomes were compared between patients with and without complications, as well as between patients with a history of major abdominal surgery and those without such a history. Laparoscopic peritoneal dialysis catheter placement was aborted in 4 patients because of an inability to safely achieve sufficient access to the abdominal cavity through dissection; these patients were excluded from subsequent analysis. The mean follow-up period was 18.8 ± 12.9 months. Fifty-five patients had a history of major abdominal surgery compared with 61 without such a history. No significant difference was observed with respect to age, race, sex, or body mass index between groups. Notably, more adjunctive procedures were required in patients with previous abdominal surgery, including adhesiolysis (60.0% vs 4.9%, P peritoneal dialysis for nonsurgical reasons. Laparoscopic peritoneal dialysis catheter placement offers a chance to establish peritoneal dialysis access in patients traditionally viewed as noncandidates for this modality. Despite the potential risks incurred because of additional procedures at the time of catheter placement in these complicated cases, these patients can achieve good long-term peritoneal dialysis access with an aggressive surgical approach.

    Encapsulating peritoneal sclerosis (EPS) is a rare but severe complication of peritoneal dialysis (PD) characterized by extensive fibrosis of the peritoneum. Changes in peritoneal water transport may precede EPS, but the mechanisms and potential predictive value of that transport defect are unknown. Among 234 patients with ESRD who initiated PD at our institution over a 20-year period, 7 subsequently developed EPS. We evaluated changes in peritoneal transport over time on PD in these 7 patients and in 28 matched controls using 3.86% glucose peritoneal equilibration tests. Compared with long-term PD controls, patients with EPS showed early loss of ultrafiltration capacity and sodium sieving before the onset of overt EPS. Multivariate analysis revealed that loss of sodium sieving was the most powerful predictor of EPS. Compared with long-term PD control and uremic peritoneum, EPS peritoneum showed thicker submesothelial fibrosis, with increased collagen density and a greater amount of thick collagen fibers. Reduced osmotic conductance strongly correlated with the degree of peritoneal fibrosis, but not with vasculopathy. Peritoneal fibrosis was paralleled by an excessive upregulation of vascular endothelial growth factor and endothelial nitric oxide synthase, but the expression of endothelial aquaporin-1 water channels was unaltered. Our findings suggest that an early and disproportionate reduction in osmotic conductance during the course of PD is an independent predictor of EPS. This functional change is linked to specific alterations of the collagen matrix in the peritoneal membrane of patients with EPS, thereby validating the serial three-pore membrane/fiber matrix and distributed models of peritoneal transport.

    Ultrafiltration failure (UFF) is a complication of peritoneal dialysis (PD) treatment that occurs especially in long-term patients. Etiological factors include a large effective peritoneal surface area [measured as high mass transfer area coefficient (MTAC) of creatinine], a high effective lymphatic absorption rate (ELAR), a large residual volume, or combinations. The prevalence and etiology of UFF were studied and the contribution of transcellular water transport (TCWT) was analyzed. A new definition of UFF and guidelines for the analysis of its etiology were derived from the results. Peritoneal dialysis unit in the Academic Medical Center in Amsterdam. Cross-sectional study of standard peritoneal permeability analyses (4-hr dwells, dextran 70 as volume marker) with 1.36% glucose in 68 PD patients. Patients with negative net UF (change in intraperitoneal volume, dIPV rate (TCUFR) were lower (p lower residual volume (p = 0.03), and lower TCUFR (p = 0.01). Ultrafiltration failure was associated with a high MTAC creatinine in 3 patients, a high ELAR in 4 patients, and a combination of factors in one. As an additional possible cause, TCWT was studied, using the sodium gradient in the first hour of the dwell, corrected for diffusion (dNA). Five patients had dNA > 5 mmol/L, indicating normal TCWT. The 3 patients with dNA lower TCUFR (p = 0.04). A smaller difference was found between dIPV 3.86% and 1.36% (p = 0.04) compared to the dNA > 5 mmol/L group, but no differences were present for MTAC creatinine, ELAR, residual volume, or glucose absorption. In addition to known factors, impairment of TCWT can be a cause of UFF. A standardized dwell with 1.36% glucose overestimates UFF. Therefore, 3.86% glucose should be used for identification of patients with UFF, especially because it provides additional information on TCWT. Ultrafiltration failure can be defined as net UF exchange.

    A 17-month-old male Labrador retriever presented for evaluation of an abdominal mass felt during abdominal palpation. Multiple variably sized cystic masses were identified on sonographic and radiographic images. Exploratory laparotomy revealed multiple peritoneal masses that exhibited atypical contractions and lacked an identifiable organ of origin. Histology and immunohistochemistry of multiple surgically excised masses was consistent with benign tumors of smooth muscle origin (leiomyomas). The presence of multiple peritoneal leiomyomas in this dog is consistent with disseminated peritoneal leiomyomatosis. Two years after diagnosis and multiple surgical interventions, continual insidious enlargement of leiomyomas was identified on ultrasound and CT. © 2014 American College of Veterinary Radiology.

    Benign multicystic peritoneal mesothelioma is an uncommon lesion arising from the peritoneal mesothelium. It is asymptomatic or presents with unspecific symptoms. Imaging techniques may reveal it, however the final diagnosis can only be made by histopathology. Surgery is the only effective treatment considering its high recurrence rate. We report a 19 years old male with Crohn’s disease. Due to persistent abdominal pain, an abdominal magnetic resonance imaging was performed, showing a complex cystic mass in the lower abdomen. The patient underwent surgery and the lesion was completely resected. The pathological study reported a benign multicystic peritoneal mesothelioma.

    Full Text Available Fungal peritonitis (FP is a rare, but serious complication of peritoneal dialysis. We analyzed the incidence of FP, associated risk factors and outcome of patients with FP and evaluated the role of prophylactic antifungal agent in reducing its incidence. We studied all patients with FP from January 2005 to January 2012. Study period was divided into two parts, period I (January 2005 to January 2010, when prophylactic antifungal was not used and period II (January 2010 to January 2012, when prophylactic antifungal (fluconazole was used. A total of 142 episodes of peritonitis were documented during this period of which 20 (14% were FP. During the study period I, 18 of 102 episodes of peritonitis (17.6% and in the study period II (with antifungal prophylaxis, only 2 of 40 episodes of peritonitis (5% were due to fungal infection (P = 0.04. Nine out of 20 patients (45% had prior exposure to antibiotics. Fungal isolates were Candida albicans in 65%, non-albicans Candida in 25%, Rhizopus species in 5% and Alternaria in 5% of the patients. While 12 out of 20 patients (60% recovered completely and were re-initiated on continuous ambulatory peritoneal dialysis (CAPD, 4 of them expired (20% and 4 others (20% were shifted to hemodialysis. Use of prophylactic antifungal agent significantly reduced the incidence of FP (P = 0.04. We conclude that - fluconazole when used as a prophylactic agent in the setting of bacterial peritonitis significantly reduces the incidence of subsequent FP in CAPD patients.

    Full Text Available Malignant mesothelioma is a highly aggressive neoplasm. The incidence of malignant mesothelioma is increasing worldwide. Diffuse malignant peritoneal mesothelioma (DMPM represents one-fourth of all mesotheliomas. Association of asbestos exposure with DMPM has been observed, especially in males. A great majority of patients present with abdominal pain and distension, caused by accumulation of tumors and ascitic fluid. In the past, DMPM was considered a pre-terminal condition; therefore attracted little attention. Patients invariably died from their disease within a year. Recently, several prospective trials have demonstrated median survival of 40 to 90 months and 5-year survival of 30% to 60% after the combined treatment using cytoreductive surgery and perioperative intraperitoneal chemotherapy. This improvement in survival has prompted new searches into the medical science related to DMPM, a disease previously ignored as uninteresting. This review article focuses on the key advances in the epidemiology, diagnosis, staging, treatments and prognosis of DMPM that have occurred in the past decade.

    Full Text Available Background. Pelvic inflammatory disease (PID rarely results in diffuse ascites. Severe adhesive disease secondary to PID may lead to the formation of inclusion cysts and even pelvic peritoneal nodularity due to postinflammatory scarring and cause an elevation of serum CA-125 levels. The constellation of these findings may mimic an ovarian neoplasm. Case. We report a case of a 22-year-old female who presented with multiple pelvic cysts and diffuse ascites due to Chlamydia trachomatis infection. The initial gynecologic exam did not reveal obvious evidence of PID; however, a positive Chlamydia trachomatis test, pathologic findings, and the exclusion of other etiologies facilitated the diagnosis. Conclusion. Chlamydia trachomatis and other infectious agents should be considered in the differential diagnosis of a young sexually active female with abdominal pain, ascites, and pelvic cystic masses. Thorough workup in such a population may reduce the number of more invasive procedures as well as unnecessary repeat surgical procedures.

    One of the side effects of peritoneal photodynamic treatment (PDT) of mice is a systemic suppression of contact hypersensitivity (CH) responses. Treatment with either laser alone or the photosensitizer, Photofrin II (PFII), alone does not cause suppression of CH responses. Immunosuppression of CH responses is an active process that is adoptively transferable using viable cells, but not serum, from PDT-treated mice. The induction of adoptively transferable suppressor cells in PDT-treated mice requires exposure to an antigenic stimulus, yet the suppressor cells are antigen non-specific in their function. T cell function in PDT-treated mice, as measured by the ability of splenic lymphoid cells to generate allogeneic cytotoxic T lymphocyte responses, is comparable to that detected in normal mice. However, the ability of spleen cells from PDT-treated mice to act as stimulators in a mixed lymhocyte reaction is dramatically impaired, suggesting that the major cell type affected by peritoneal PDT is of the macrophage lineage. Support for this concept is provided by experiments in which spleen cells from PDT-treated mice were chromatographically separated into populations of T cells, B cells and macrophages prior to adoptive transfer into naive recipients. The results indicate that the cell type mediating adoptively transferable suppression of CH responsiveness is of the macrophage lineage. Analysis of hematologic parameters revealed that induction of suppression by PDT-treatment was associated with a marked neutrophilia and lymphocytosis, and was also accompanied by a 5-fold increase in concentration of the acute phase protein, Serum Amyloid P. Finally, attempts to ameliorate PDT-induced immunosuppression by pharmacologic intervention have proved successful using implants of pellets that release indomethacin at a rate of 1.25µg/day. Thus, the data suggest that PDT-treatment induces macrophages to produce factors (e.g., prostaglandins) that are known to be potently

    Full Text Available Yoshiyuki Morishita, Minami Watanabe, Ichiro Hirahara, Tetsu Akimoto, Shigeaki Muto, Eiji KusanoDivision of Nephrology, Department of Medicine, Jichi Medical University, Tochigi, JapanPurpose: Peritoneal dialysis (PD is a successful renal replacement therapy; however, long-term PD leads to structural and functional peritoneal damage. Therefore, the monitoring and estimation of peritoneal function are important in PD patients. Oxidative stress has been implicated as one possible mechanism of peritoneal membrane damage. The aim of this study was to evaluate the association between an oxidative stress marker, 8-hydroxydeoxyguanosine (8-OHdG, and peritoneal damage in PD patients.Methods: The authors evaluated 8-OHdG in drained dialysate by enzyme immunoassay to investigate the association between 8-OHdG and solute transport rate estimated by peritoneal equilibration test and matrix metalloproteinase-2 (MMP-2 level in 45 samples from 28 PD patients.Results: The 8-OHdG level was significantly correlated with dialysate:plasma creatine ratio (r = 0.463, P < 0.05 and significantly inversely correlated with D/D0 glucose (where D is the glucose level of peritoneal effluents obtained 4 hours after the injection and D0 is the glucose level obtained immediately after the injection (r = -0.474, P < 0.05. The 8-OHdG level was also significantly correlated with MMP-2 level (r = 0.551, P < 0.05, but it was not correlated with the age of subjects, the duration of PD, or blood pressure.Conclusion: The level of 8-OHdG in drained dialysate may be a useful novel marker of peritoneal damage in PD.Keywords: oxidative stress, solute transport rate, MMP-2, peritoneal equilibration test

    Full Text Available Aunque se han descrito numerosos materiales para rellenar una cavidad ósea, el mejor material sigue siendo el hueso autólogo corticoesponjoso o particulado, que puede formar hueso nuevo por mecanismos de osteogénesis, osteinducción y osteoconducción. El cirujano oral y maxilofacial debe conocer las propiedades biológicas y las características fundamentales de los materiales autólogos, las diferentes técnicas de obtención y sus aplicaciones clínicas. Como zonas donantes se emplean preferentemente las intraorales, el filtro de hueso y los raspadores para pequeños defectos, y el hueso ilíaco, tibia o calota cuando se requiere más cantidad. No existen estudios concluyentes respecto a la asociación de injertos óseos con membranas. La combinación de injertos autólogos con otros materiales de relleno, ha desembocado en múltiples estudios, sin que se puedan establecer conclusiones definitivas por el momento. El hueso autólogo es de elección para el relleno de cavidades óseas, ya que es útil para dar solución a variadas situaciones clínicas de forma simple, rápida y segura.Although a large number of materials have been described for augmenting bone cavities, the best material is still autologous cortical-cancellous bone or bone chip, which can form new bone through osteogenesis, osteoinduction and osteoconduct ion mechanisms.

    Full Text Available Lactobacillus species colonize the human gastrointestinal tract and are rarely pathogenic. We present a case involving a cirrhotic patient who presented with sepsis and was found to have peritoneal cultures demonstrating Lactobacillus as the sole pathogen concerning for spontaneous bacterial peritonitis. Treatment was achieved with high-dose penicillin and clindamycin but the patient developed hepatorenal syndrome and died from acute renal failure. Intra-abdominal Lactobacillus infections are typically seen in patients undergoing peritoneal dialysis or who have recently had bowel perforation. There are few case reports of spontaneous Lactobacillus peritonitis in patients with cirrhosis. Our case report addresses the challenges of Lactobacillus treatment and suggests antibiotic coverage of commensal organisms in patients who do not improve with standard management.

    Peritoneal carcinomatosis (PC) is a cancer disease with an urgent need for effective treatment. Conventional chemotherapy failed to show acceptable results. Cytoreductive surgery and hyperthermic chemoperfusion (HIPEC) are only beneficial in few patients with resectable peritoneal metastasis. Immunotherapy could be attractive against PC, as all requirements for immunotherapy are available in the peritoneal cavity. This review analyzes the present literature for immunotherapy of PC. Advances from immune stimulators, radionucleotide-conjugated- and bispecific antibodies to future developments like adoptive engineered T-cells with chimeric receptors are discussed. The clinical development of catumaxomab, which was the first intraperitoneal immunotherapy to be approved for clinical treatment, is discussed. The requirements for future developments are illustrated. Expert commentary: Immunotherapy of peritoneal carcinomatosis is manageable, showing striking cancer cell killing. Improved profiles of adverse events by therapy-induced cytokine release, enhanced specific killing and optimal treatment schedules within multimodal treatment will be key factors.

The aim of our study was to evaluate iron levels in peritoneal fluid (PF) of women with and without endometriosis. Seventy-five women were studied: 50 women with endometriosis and, as a reference group, 25 patients with functional follicle ovarian cysts. Iron concentrations in the PF were measured using a commercially available colorimetric assay kit. Iron concentrations were significantly higher in PF from women with endometriosis as compared to the reference group. Patients with stages III/IV endometriosis had significantly higher PF iron concentrations than women with stages I/II of the disease. Disrupted iron homeostasis in the peritoneal cavity of women with endometriosis plays a role in the pathogenesis of the disease.

    Massive hydrothorax complicating continuous ambulatory peritoneal dialysis (CAPD) is relatively rare. A 67-year-old male and a 23-year-old female patients during CAPD presented massive pleural effusion, They have been performing peritoneal dialysis due to end-stage renal disease for 8 months and 2 weeks respectively. We injected '9{sup 9m}Tc-labelled radiopharmaceutical (phytate and MAA, respectively) into peritoneal cavity with the dialysate. The anterior, posterior and right lateral images were obtained. The studies reveal visible radioactivity in the right chest indicating the communication between the peritoneal and the pleural space. After sclerotherapy with tetracycline, the same studies reveal no radioactivity in the right chest suggesting successful therapy. We think nuclear imaging is a simple and noninvasive method for the differential diagnosis of pleural effusion in patients during CAPD and the evaluation of therapy.

    Late postoperative intra-abdominal infections after laparoscopic gastric banding are extremely rare and may or may not be associated with the device following uncomplicated adjustable gastric banding procedures. The spectrum of pathogens associated with intra-abdominal infections is diverse and depends on the origin of the infection. Streptococci is a significant cause of peritoneal dialysis peritonitis (6% to 16% of the cases), and S. viridans is reported to account for up to 93% of streptococci infections. However, peritonitis due to S. viridans in patients following adjustable gastric banding is very rare. We herein report a non-uremic case of a 38-year-old male patient with severe peritonitis due to S. viridans 5 years after an uneventful primary gastric banding procedure.

    Full Text Available End stage renal disease diabetic patients suffer from worse clinical outcomes under dialysis-independently of modality. Peritoneal dialysis offers them the advantages of home therapy while sparing their frail vascular capital and preserving residual renal function. Other benefits and potential risks deserve discussion. Predialysis intervention with early nephrology referral, patient education, and multidisciplinary support are recommended. Skilled and updated peritoneal dialysis protocols must be prescribed to assure better survival. Optimized volume control, glucose-sparing peritoneal dialysis regimens, and elective use of icodextrin are key therapy strategies. Nutritional evaluation and support, preferential use of low-glucose degradation products solutions, and prescription of renin-angiotensin-aldosterone system acting drugs should also be part of the panel to improve diabetic care under peritoneal dialysis.

    Peritoneal tuberculosis may lead to delayed diagnosis because of the nonspecific features such as fever, abdominal distension, abdominal tenderness, ascites, and weight loss. Here, wereported a case of prolonged fever and abdominal pain which was due to peritoneal tuberculosis. Initial examinations including acomplete blood test and serologic tests did not lead to the diagnosis. A final diagnosis was made by abdominal CT-scan and laparoscopy combined with histopathological studies. Antituberculous medications provided a good clinical response in this patient.

    To investigate possible mechanisms of pain pathophysiology in patients with peritoneal endometriosis, a clinical study on sensory and sympathetic nerve fibre sprouting in endometriosis was performed. Peritoneal lesions (n=40) and healthy peritoneum (n=12) were immunostained and analysed with anti-protein gene product 9.5 (PGP 9.5), anti-substance P (SP) and anti-tyrosine hydroxylase (TH), specific markers for intact nerve fibres, sensory nerve fibres and sympathetic nerve fibres, respectively, to identify the ratio of sympathetic and sensory nerve fibres. In addition, immune cell infiltrates in peritoneal endometriotic lesions were analysed and the nerve growth factor (NGF) and interleukin (IL)-1β expression was correlate with the nerve fibre density. Peritoneal fluids from patients with endometriosis (n=40) and without endometriosis (n=20) were used for the in vitro neuronal growth assay. Cultured chicken dorsal root ganglia (DRG) and sympathetic ganglia were stained with anti-growth associated protein 43 (anti-GAP 43), anti-SP and anti-TH. We could detect an increased sensory and decreased sympathetic nerve fibres density in peritoneal lesions compared to healthy peritoneum. Peritoneal fluids of patients with endometriosis compared to patients without endometriosis induced an increased sprouting of sensory neurites from DRG and decreased neurite outgrowth from sympathetic ganglia. In conclusion, this study demonstrates an imbalance between sympathetic and sensory nerve fibres in peritoneal endometriosis, as well as an altered modulation of peritoneal fluids from patients with endometriosis on sympathetic and sensory innervation which might directly be involved in the maintenance of inflammation and pain.

    Sampson's theory cannot explain why only some cycling women develop peritoneal endometriosis. Few studies have focused on the pelvic peritoneum, which receives regurgitated endometrial tissues. We hypothesized that molecular alterations in the peritoneum are involved in the development of peritoneal endometriosis and conducted a microarray analysis to compare macroscopically normal peritoneum sampled from women with peritoneal endometriosis (endometriotic peritoneum) and those without (non-endometriotic peritoneum). Versican, a major proteoglycan component of the extracellular matrix, is one of the molecules up-regulated in endometriotic peritoneum. To investigate the role of versican in peritoneal endometriosis. Design, Patients, and Main Outcome Measure: Endometriotic peritoneum and non-endometriotic peritoneum were subjected to RT-PCR, immunostaining, and Western blotting. The versican V1 isoform was stably transfected into Chinese hamster ovary cells (CHO-V1), and the effects of CHO-V1-derived conditioned medium (V1-CM) on primary human endometrial stromal cells were investigated with attachment, invasion, and proliferation assays. The effects of peritoneal fluid collected from endometriotic women (endometriotic PF) or cytokines/growth factors, which were shown to be elevated in endometriotic PF, on versican expression in a human peritoneal cell line (HMrSV5) were also examined. Versican V1 expression levels were significantly higher in endometriotic peritoneum. In vitro, V1-CM promoted attachment to the HMrSV5 cell monolayer as well as the Matrigel invasion of endometrial stromal cells. Although versican V1 expression was up-regulated by TGF-β1 in HMrSV5 cells, it remained unchanged in endometriotic PF. Our results suggest the involvement of peritoneal versican in the development of peritoneal endometriosis.

  9. Ultrafiltration Failure and Impaired Sodium Sieving During Long-Term Peritoneal Dialysis: More Than Aquaporin Dysfunction?

    Science.gov (United States)

    Morelle, Johann; Sow, Amadou; Hautem, Nicolas; Devuyst, Olivier; Goffin, Eric

    2016-01-01

    Fifteen years ago, our group reported the case of a 67-year-old man on peritoneal dialysis for 11 years, in whom ultrafiltration failure and impaired sodium sieving were associated with an apparently normal expression of aquaporin-1 (AQP1) water channels in peritoneal capillaries. At that time, AQP1 dysfunction was suggested as the cause of impaired free-water transport. However, recent data from computer simulations, and structural and functional analysis of the peritoneal membrane of patients with encapsulating peritoneal sclerosis, demonstrated that changes in the peritoneal interstitium directly alter osmotic water transport. In light of these insights, we challenge the initial hypothesis and provide several lines of evidence supporting the diagnosis of encapsulating peritoneal sclerosis in this patient and suggesting that severe peritoneal fibrosis accounted for the loss of osmotic conductance developed during the course of peritoneal dialysis.

    Eosinophilic peritonitis is a well-described complication of peritoneal dialysis and is often associated with either a reaction to the dialysis system constituent (tubing, sterilant or solution) or an underlying bacterial or fungal reaction. We report a case of eosinophilic peritonitis, which is treated by oral prednisone acetate therapy. A 43-year-old female patient developed end-stage renal disease and underwent continuous ambulatory peritoneal dialysis for 2.5 years. The patient received 2,000 ml of 1.5% dialysis solution (PD2) with three exchanges daily and 2,000 ml of 2.5% PDF overnight (PD2). She went to the consultation because of a constant turbid peritoneal dialysis effluent for 3 months without abdominal pain. Repeated peritoneal effluent samples showed an elevated white blood cell count of 500 cells/mm(3), with 87% eosinophils. The peripheral blood test revealed a white blood cell count of 3.8 × 10(9)/l, with 32.2% eosinophils. Etiology like bacterial and fungal infection was excluded by peritoneal fluid culture. Turbidness persisted in spite of diagnostic antibiotic treatment. Given the fact that we found a significant elevation of eosinophils in the peripheral blood and an absolute increase in the eosinophil count of >30/mm(3) in dialysis fluid (up to 400/mm(3) in our patient), obvious dialysate effluent turbidness, negative results of repeated peritoneal fluid cultures, inefficacy of antibiotic therapy, and negativity of serum tumor and immunological markers, we drew the conclusion that the patient had idiopathic eosinophilic peritonitis. Oral corticosteroid was administered at once (20 mg prednisone acetate daily), which was gradually weaned off and stopped over an 8-week period. Afterwards, the dialysis effluent became clear, and the cytological analysis showed that the white blood cell count decreased to 1 × 10(6)/l, with no eosinophils. This case reminds us that the diagnosis of eosinophilic peritonitis should be considered when repeated

    Peritoneal dialysis (PD) constitutes the preferred dialysis modality for children requiring renal replacement therapy with peritonitis being one of the most common complications of PD. This study was performed to evaluate the epidemiology, microbiology, and outcomes of PD-associated peritonitis in Greek children for a 10-year period. A total of 27 patients (16 males) with a mean age 121.8 ± 57.2 months were retrospective analyzed. Patients were on PD therapy for a mean duration of 45.2 ± 26.1 months. We found 23 episodes of PD-associated peritonitis occurred in 9 out of 27 patients (0.23 episodes/patient-year), with four patients experienced two or more peritonitis episodes. Gram-positive bacteria were responsible for 15 (65.2%) peritonitis episodes, with Staphylococcus aureus being the predominant specie isolated in 30.4% of cases. A total of seven episodes of exit-site infections (ESIs) were identified in five patients (0.069 episodes/patient-year) with the most common bacteria isolated being S. aureus (57.4%). Initial antibiotic treatment included intraperitoneal vancomycin plus ceftazidime in the majority of cases (82.6%). At the end of study, 12 (44.4%) patients remained on PD, 11 (41.8%) underwent renal transplantation, 2 (7.4%) shifted to hemodialysis and unfortunately, two patients (7.4%) died. Conclusively, our study revealed a noticeable low peritonitis and ESIs rate as compared to international data and represents the first evaluation of the characteristics and outcomes of peritonitis in the Greek pediatric PD population.

    Sclerosing peritonitis is a serious complication of CAPD characterised by thickened peritoneal membranes which lead to decreased ultrafiltration and intestinal obstruction. The roentgenographic signs of SP were analysed in 11 patients who underwent plain X-ray of the abdomen, follow-through examinations of the small bowel, ultrasonography and computed tomography. Results were correlated with the histological degree of SP. Due to the fact that postoperative complications often occur in patients with SP, detection of the radiological signs should lead to cautious surgical interventions and changeover to haemodialysis.

    What are the features of peritoneal macrophage subgroups and T helper cells in the development of murine endometriosis? During the development of endometriosis in a murine model, large peritoneal macrophages (LPMs) and small peritoneal macrophages (SPMs) are polarized into M1 and M2 cells, respectively, and the proportions of T helper (Th) 1, Th17 and T regulatory (T reg ) cells are increased. Numerous studies investigating the etiology and pathogenesis of endometriosis have focused on the polarization states of peritoneal macrophages in endometriosis models and patients, but the results are inconclusive. Further studies indicate that peritoneal macrophages are composed of two distinct subsets: LPMs and SPMs, although their roles in endometriosis are unknown. This study involves a prospective and randomized experiment. Fifty C57BL/6 female mice were randomly allocated to five control and five experimental groups (n = 5/group) according to the presence or absence of transplantation. The transplant periods are 0.25, 3, 14, 28 and 42 days. C57BL/6 mice were utilized to establish an endometriosis model by i.p. injection of allogeneic endometrial segments. Dynamic changes of peritoneal macrophage subsets and polarization profiles were evaluated by flow cytometry (FCM). Macrophage morphology and density were assessed by cell counting under a microscope. Dynamic changes of Th1, Th2, Th17 and T reg cells were estimated by FCM. Peritoneal macrophages are composed of two distinct subsets: LPMs and SPMs. The proportion of SPMs increased immediately after peritoneal injection of endometrial tissues, whereas LPMs showed an opposite trend. Peritoneal macrophages differentiated into both M1 and M2 macrophages. The bidirectional polarization of macrophages was caused by the inverse trends of polarization of LPMs and SPMs. Consistently, the proportions of Th1, Th17 and T reg cells were all increased in mice with endometriosis.

    This article reports on the clinical practice guidelines developed by a multidisciplinary group working on the indications and uses of the various available treatment options for relieving intestinal obstruction or its symptoms in patients with peritoneal carcinomatosis. These guidelines are based on a literature review and expert opinion. The recommended strategy involves a clinical and radiological evaluation, of which CT of the abdomen is a crucial component. The results, together with an analysis of the prognostic criteria, are used to determine whether surgery or stenting is the best option. In most patients, however, neither option is feasible, and the main emphasis, therefore, is on the role and administration of various symptomatic medications such as glucocorticoids, antiemetic agents, analgesics, and antisecretory agents (anticholinergic drugs, somatostatin analogues, and proton-pump inhibitors). Nasogastric tube feeding is no longer used routinely and should instead be discussed on a case-by-case basis. Recent studies have confirmed the efficacy of somatostatin analogues in relieving obstruction-related symptoms such as nausea, vomiting, and pain. However, the absence of a marketing license and the high cost of these drugs limit their use as the first-line treatment, except in highly selected patients (early recurrence). When these medications fail to alleviate the symptoms of obstruction, venting gastrostomy should be considered promptly. Rehydration is needed for virtually every patient. Parenteral nutrition and pain management should be adjusted according to the patient needs and guidelines. Copyright © 2014 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc.

    Endometriosis is a common disorder that causes significant morbidity from dysmenorrhea, pelvic pain, and subfertility. Establishment of a definitive diagnosis has important therapeutic implications; however, only approximately 50% of biopsies of laparoscopically suspicious areas provide a diagnosis of endometriosis. Histologic criteria for diagnosis require the presence of endometrial glands or endometrial-type stroma. We hypothesize that other frequently present, but nondiagnostic, histologic features of endometriosis suggest its presence in patients with nondiagnostic peritoneal biopsies. We performed a retrospective clinicopathologic study of morphologic and immunohistochemical features that may improve the histologic diagnosis of endometriosis on laparoscopic peritoneal biopsies. We compared diagnostic (n=88) and nondiagnostic (n=54) peritoneal biopsies from pathologically confirmed endometriosis cases with negative peritoneal biopsies (n=84) from early-stage gynecologic cancer cases. Statistical analysis utilized the Fisher exact test. Multiple morphologic features were significantly increased in nondiagnostic biopsies from patients with endometriosis in comparison with those from negative controls, including foamy macrophages (P=0.0001) and submesothelial stromal clusters (SSCs) (P=0.0008). SSCs ranged from subtle aggregates of spindle cells to nodules of whorled spindle cells with small vessels and extravasated red blood cells resembling stromal endometriosis. Immunohistochemical studies confirmed that ER and CD10-positive SSCs were present in a greater proportion of both nondiagnostic and diagnostic peritoneal biopsies and at a greater number of lesions per biopsy. The overall histologic detection rate of peritoneal biopsies for endometriosis was 62.0%, and inclusion of SSCs with or without foamy macrophages in the diagnostic criteria appreciably increased this rate to between 72.5% and 76.8%. We describe SSCs, which appear to be an early or less developed

    Increased peritoneal eicosanoid concentrations have been reported in endometriosis patients and might be important in disease-associated pain and inflammation. Here, we evaluated the expression of key biosynthetic and catabolic enzymes involved in this abnormal eicosanoid production in peritoneal macrophages and endometriotic lesions. Peritoneal macrophages, endometriotic lesions and matched eutopic endometrium were collected from endometriosis patients (n = 40). Peritoneal macrophages and eutopic endometrium samples were also collected from disease-free women (n = 25). Expression of type IIA secretory phospholipase A(2) (sPLA(2)-IIA), cyclooxygenase-2 (COX-2), microsomal prostaglandin E synthase-1 (mPGES-1), 15-hydroxyprostaglandin dehydrogenase (15-PGDH) and 5-lipoxygenase (5-LO) was quantified by real-time PCR, and these five key enzymes were localized by immunohistochemistry. sPLA(2)-IIA, COX-2 and mPGES-1 mRNA was significantly increased in peritoneal macrophages of endometriosis patients compared with controls (P = 0.006, P = 0.016 and P = 0.025, respectively). In endometriosis patients, sPLA(2)-IIA, mPGES-1 and 15-PGDH mRNA was significantly enhanced in peritoneal lesions compared with matched eutopic endometrium (P endometriosis group compared with controls (P = 0.023). Finally, sPLA(2)-IIA, COX-2, mPGES-1 and 15-PGDH immunostaining was found mainly in endometrial glands, whereas 5-LO was distributed throughout the glands and stroma. Our study highlights an imbalance between eicosanoid biosynthesis and degradation in endometriosis patients. Both peritoneal macrophages and endometriotic lesions may be involved. Research into new molecules inhibiting biosynthetic enzymes (such as sPLA(2)-IIA and mPGES-1) and/or activating catabolic enzymes (such as 15-PGDH) may prove to be a major field of investigation in the development of targeted medical therapies.

    Over a period of 6.5 years, we treated 19 patients, all of whom suffered from severe heart failure and various stages of chronic kidney disease, excluding those with end-stage kidney failure. Before peritoneal catheter implantation, all patients had ascites, dyspnea, orthopnea, and an ejection fraction ranging from 20 to 45%. Seven of them (7/19) were able to take care of themselves, 9/19 needed assistance for their daily activities, and the remaining 3 were bedridden. All of them needed hospitalization 1 - 3 times/month during the year before the initiation of continuous ambulatory peritoneal dialysis (CAPD). With peritoneal dialysis, daily ultrafiltrate volume ranged from 500 to 3,000 ml and, after an average of 2 months of peritoneal dialysis, body weight decreased significantly (74.7 ± 13 vs. 69.7 ± 10.2, p = 0.02). At the same time, diuresis improved significantly, and this allowed a reduction in the dose of diuretics. Dyspnea and orthopnea improved significantly in all patients. The patients' degree of self-care and ability to sleep lying flat improved significantly as the need for hospitalization declined. Before peritoneal dialysis, patients were hospitalized for 5 - 20 days/month for pulmonary edema or overhydration, whereas with peritoneal dialysis, nobody was hospitalized for these causes (chi2, p = 0.0001). Ejection fraction also improved in all of them (28.6 ± 8.6 vs. 36.8 ± 12.5%, p = 0.0001). Actual survival of our patients ranged from 6 to 86 months (mean ± SD = 24.6 ± 20.8). Actuarial survival was 68% at 1 year and 42% at 2 years. During peritoneal dialysis we observed only two episodes of peritonitis. Four patients developed a severe episode of hypotension during implantation of the catheters from the sudden removal of 4 - 6 l of ascitic fluid. We conclude that peritoneal dialysis is a good method for the treatment of congestive heart failure because it increases the quality of life and life expectancy in patients with poor prognosis.

    Full Text Available Background: Despite a high prevalence of endometriosis, there still exist many challenges indiagnosing the disease. This study aims to evaluate non-invasive and practical diagnostic methodsby measuring serum and peritoneal fluid CA 125 levels in patients with endometriosis. A secondaryaim is to determine the correlation between these markers with the stage of disease as well as therelationship of the two markers with each other.Materials and Methods: This is a cross-sectional study of 60 women who underwent laparoscopyfor benign conditions. Based on laparoscopic findings and biopsy results, patients were divided to twogroups; one group included patients with pelvic endometriosis (35 patients and the second enrolledpatients free from endometriosis (25 patients. Serum and peritoneal fluid specimens were provided at thetime of laparoscopy and CA125 levels were then assessed by electrochemiluminescence immunoassay.Results: Mean serum and peritoneal fluid CA125 levels were significantly higher in women withendometriosis as compared to the control group (26.42 ± 24.34 IU/ml versus 12.64 ± 6.87 IU/mlin serum and 2203.54 + 993.19 IU/ml versus 1583.42 ± 912.51 IU/ml in peritoneal fluid, p<0.05.CA 125 levels also varied proportionally with the stage of endometriosis; but showed a significantdifference only in higher stages of the disease, both in serum and peritoneal fluid. We calculatedthe cut-off value suggesting a diagnosis of pelvic endometriosis as 14.70 IU/ml for serum and1286.5 IU/ml for peritoneal fluid CA125. A linear correlation between CA 125 levels in serum andperitoneal fluid in patients with pelvic endometriosis has also been observed.Conclusion: Serum and peritoneal fluid CA 125 levels are simple and non-surgical tools fordiagnosing and staging pelvic endometriosis. These markers are of greater diagnostic value inhigher stages of the disease.

  7. CD90+ mesothelial-like cells in peritoneal fluid promote peritoneal metastasis by forming a tumor permissive microenvironment.

    Joji Kitayama

    Full Text Available The peritoneal cavity is a common target of metastatic gastrointestinal and ovarian cancer cells, but the mechanisms leading to peritoneal metastasis have not been fully elucidated. In this study, we examined the roles of cells in peritoneal fluids on the development of peritoneal metastasis. We found that a minor subset of human intraperitoneal cells with CD90(+/CD45(- phenotype vigorously grew in culture with mesothelial-like appearance. The mesothelial-like cells (MLC displayed the characteristics of mesenchymal stem cell, such as differentiating into adipocytes, osteocytes, and chondrocytes, and suppressing T cell proliferation. These cells highly expressed type I collagen, vimentin, α-smooth muscle actin and fibroblast activated protein-α by the stimulation with TGF-β, which is characteristic of activated myofibroblasts. Intraperitoneal co-injection of MLCs with the human gastric cancer cell line, MKN45, significantly enhanced the rate of metastatic formation in the peritoneum of nude mice. Histological examination revealed that many MLCs were engrafted in metastatic nodules and were mainly located at the fibrous area. Dasatinib, a potent tyrosine kinase inhibitor, strongly inhibited the proliferation of MLCs but not MKN45 in vitro. Nevertheless, oral administration of Dasatinib significantly inhibited the development of peritoneal metastasis of MKN45, and resulted in reduced fibrillar formation of metastatic nodules. These results suggest floating MLCs in the peritoneal fluids support the development of peritoneal metastasis possibly through the production of the permissive microenvironment, and thus the functional blockade of MLCs is a reasonable strategy to treat recurrent abdominal malignancies.

  8. Peritoneal dialysis--current status and future challenges.

    Peritoneal dialysis is now a well established, mature treatment modality for advanced chronic kidney disease. The medium term (at least 5 year) survival of patients on peritoneal dialysis is currently equivalent to that of those on haemodialysis, and is particularly good in patients who are new to renal replacement therapy and have less comorbidity. Nevertheless the modality needs to keep pace with the constantly evolving challenges associated with the provision and delivery of health care. These challenges, which are gradually converging at a global level, include ageing of the population, multimorbidity of patients, containment of cost, increasing self care and environmental issues. In this context, peritoneal dialysis faces particular challenges that include multiple barriers to the therapy and unsatisfactory and poorly defined technique survival as well as limitations relating to intrinsic aspects of the therapy, such as peritoneal membrane longevity and hypoalbuminaemia. To move the therapy forward and favourably influence health-care policy, the peritoneal dialysis community needs to integrate their research effort more effectively by undertaking clinically meaningful studies-with a strong focus on technique survival--that are supported by multidisciplinary expertise in patient-centred outcomes, study design and analysis.

    Full Text Available Objective: to evaluate the functional state of intestinal microcirculation in diffuse peritonitis caused by hollow organ perforation and to determine its possible relationship to skin microcirculation. Subjects and methods. Seventeen patients with diffuse peritonitis resulting from hollow organ perforation were examined. The patients’ mean age was 58.5±2.8 years; a control group consisted of 35 apparently healthy individuals. The functional state of the intestinal microcirculatory bed (the mid-transverse colon, the ileum at a distance of 60 cm from the ileocecal corner, the small bowel at a distance of 50 cm of the ligament of Treitz, and an area next hollow organ perforation and skin was evaluated by laser Doppler flowmetry by means of a ЛАКК-02 laser capillary blood flow analyzer made in the Russian Federation (LAZMA Research-and-Production Association, Russian Federation. Results. Perforation of the affected intestinal portion became worse in patients with diffuse peritonitis. Blood flow stability was ensured by the higher effect of mainly active components of vascular tone regulation on the microvascular bed. Regulatory changes were equally pronounced at both the intraorgan and skin levels. Conclusion. The findings suggest that the patients with diffuse peritonitis have changes in microcirculatory regulation aimed at maintaining tissue perfusion. These changes are universal at both the intraorgan and skin levels. Key words: microcirculation, micro blood flow, intestine, peritonitis, tissue perfusion.

    In the present study, we identified patients who had difficulties learning the minimum knowledge and skills required to carry out peritoneal dialysis (PD), and we compared the outcomes in this subgroup of patients with outcomes in the general PD population. We calculated the mean learning sessions needed by our total PD population during the training period. We then assigned patients to one of two groups according to the number of learning sessions they needed. Patients who required a number of sessions equal to or less than the mean were placed in the "standard learning" group; patients who required more sessions but who reached the minimum knowledge and skills were placed in the "learning difficulties " group. We compared these two groups in terms of age, sex, diabetes status, autonomy to perform PD, family support, education level, residual renal function, and Charlson comorbidity index. Outcomes on PD included time to first peritonitis episode, peritonitis rate, percentage of patients free of peritonitis during follow-up, survival time on PD, and transfer to hemodialysis. Patients with learning difficulties were older and had more comorbidities. Outcomes on PD in the learning difficulties group were similar to those in the standard learning group, except for time to first peritonitis.

    Full Text Available Introduction : Over the years various therapeutic techniques for diverticulitis have been developed. Laparoscopic peritoneal lavage (LPL appears to be a safe and useful treatment, and it could be an effective alternative to colonic resection in emergency surgery. Aim : This prospective observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage in perforated sigmoid diverticulitis. Material and methods : We surgically treated 70 patients urgently for complicated sigmoid diverticulitis. Thirty-two (45.7% patients underwent resection of the sigmoid colon and creation of a colostomy (Hartmann technique; 21 (30% patients underwent peritoneal laparoscopic lavage; 4 (5.7% patients underwent colostomy by the Mikulicz technique; and the remaining 13 (18.6% patients underwent resection of the sigmoid colon and creation of a colorectal anastomosis with a protective ileostomy. Results : The 66 patients examined were divided into 3 groups: 32 patients were treated with urgent surgery according to the Hartmann procedure; 13 patients were treated with resection and colorectal anastomosis; 21 patients were treated urgently with laparoscopic peritoneal lavage. We had no intraoperative complications. The overall mortality was 4.3% (3 patients. In the LPL group the morbidity rate was 33.3%. Conclusions : Currently it cannot be said that LPL is better in terms of mortality and morbidity than colonic resection. These data may, however, be proven wrong by greater attention in the selection of patients to undergo laparoscopic peritoneal lavage.

    Among the clinical parameters that play a pivotal role in predicting the outcome of patients with endometrial carcinoma, intraperitoneal microscopic dissemination represents an important cause of recurrences. To date, peritoneal cytology has been incorporated into the current surgical staging system (International Federation of Gynecology and Obstetrics 88), although its predictive value remains a controversial issue. In this study the authors investigated the possibility of applying immunocytochemistry (ICC) to the diagnosis of peritoneal washing (PW) aimed at improving conventional cytology and verifying the prognostic value of peritoneal malignant cells. The authors analyzed 182 PWs sampled from endometrial cancer patients. The ICC analysis was performed using two monoclonal antibodies (MAbs)--AR-3 and B72.3--that in combination recognize more than 95% of endometrial carcinomas. The presence of peritoneal-free cancer cells was identified morphologically in 27 of 182 lavages (14.8%) and ICC in 50 of 182 (27.5%), with a significant improvement (p <0.0001). Five-year survival analysis, comparing results of ICC and cytodiagnosis, demonstrated a significant decrease of disease-free survival in patients with peritoneal microscopic disease. Furthermore, multivariate analysis showed that ICC diagnosis of PWs is an independent prognostic factor. Data indicate that the use of selected MAbs allows one to identify cytologically false-negative cases, providing results that are highly predictive of a worse clinical outcome.

    Among the clinical factors with a pivotal role in the prediction of outcome for patients with gastric cancer, intraperitoneal (i.p.) microscopic dissemination may represent an important cause of recurrences, even in the early stages of the disease. In this context, the cytologic examination of intraoperative peritoneal washings may be essential to identify metastatic free cells, although a number of false-negative cases may be encountered. To determine whether immunocytochemical (ICC) methods that used a panel of three monoclonal antibodies (MoAbs), B72.3, AR3, and BD5, directed to gastric cancer-associated antigens can improve peritoneal cytology by providing more accurate prognostic indications, we immunocytochemically and morphologically evaluated 144 peritoneal washings sampled from patients surgically treated for gastric cancer. The ICC analysis allowed the identification of metastatic free peritoneal cells in 35% of the patients, with a 14% improvement over routine cytopathology (P < .0001). Furthermore, a 54-month survival analysis by Kaplan-Meier curves showed a statistically significant decrease in overall survival (OS) in patients with stages I through III disease with peritoneal microscopic disease detected morphologically and/or by ICC at the time of the primary surgery. Our data indicate that the use of a combination of selected MoAbs may allow the identification of cytologically false-negative cases that provide valuable prognostic information. This may be useful to stratify patients on more adequate therapeutic trials.

    Patients suffering from severe sepsis originating in the abdominal peritoneal region frequently require re-interventions, as this condition persist with high morbidity.Management of therapy is difficult and tends to be controversial; existing studies consider a universe which that is far from homogenic.The analysis covers a five year period.Case material involved 55 patients with severe abdominal sepsis requiring at least one re laparotomy.It takes into considerations the incidence, clinical manifestations leading to a positive re laparotomy, death rate and factors involved in prognosis.The absence of multi organic dysfunction (MOD) was considered a valid criteria for exclusion. A total of 121 relapses with corresponding laparotomy were performed, of which 17(14%) showed no relapse.The latter was less frequently associated with the presence of prolonged symptomatology, gastrointestinal anastomosis and /or MOD at the time of re-laparotomizing the patient (p<0,05).Local signs proved to be poor indicators of the advisability to re laparotomize. When comparing programmed re-laparotomy with this procedure undertaken whenever it be required, no differences were established as to the number of interventions performed, mean hospital days of patients and mortality. Crude mortality was 76% and related death-rate was 55%.The oldest patient was 70 years of age, the A:P:A:C:H:E: II points exceeded 17 and the presence of 3 or more sys functions were significantly associated with death rate in the range of 90%.The conclusion of this stud was that, given the high mortality of patients with 3 or more dysfunctions, the strategy for improving death rate is to re operate at an early stage those patients with 1 or 2 dysfunctions,particularity those presenting prolonged symptoms and/or gastrointestinal anastomosis

HPSEC-MALLS/RI analysis showed that each polysaccharide fraction was homogeneous; M(w) values were 1.6 x 10(5), 2.0 x 10(5) and 1.5 x 10(5)g/mol, respectively. The effect of the xyloglucans on the production of O(2)*(-) and NO* and on the recruitment of macrophages to the mouse peritoneum was evaluated. All polysaccharides promoted an increase in the number of peritoneal macrophages in a dose-dependent manner. The largest increase, of 576% in comparison to the control group, was elicited by XGJ at 200 mg/kg. The effect of XGC, XGJ and XGM on O(2)*(-) production, in the presence or absence of phorbol 12-myristate 13-acetate (PMA), was not statistically significant. For NO(.) production, the lowest concentration of XGC (10 microg/ml) gave rise to an increase of 262% when compared to the control group; the effect was dose-dependent, reaching 307% at 50 microg/ml. On the other hand, XGJ at a concentration of 50 microg/ml enhanced NO* production by 92%. XGM did not affect NO* production significantly. The results indicate that xyloglucans from C. langsdorffii, H. courbaril and M. sloanei have immunomodulatory activity.

    The future growth of peritoneal dialysis (PD) will be directly linked to the shift in US healthcare to a value-based payment model due to PD's lower yearly cost, early survival advantage over in-center hemodialysis, and improved quality of life for patients treating their kidney disease in the home. Under this model, nephrology practices will need an increased focus on managing the transition from chronic kidney disease to end-stage renal disease (ESRD), providing patient education with the aim of accomplishing modality selection and access placement ahead of dialysis initiation. Physicians must expand their knowledge base in home therapies and work toward increased technique survival through implementation of specific practice initiatives that highlight PD catheter placement success, preservation of residual renal function, consideration of incremental PD, and competence in urgent start PD. Avoidance of both early and late PD technique failures is also critical to PD program growth. Large dialysis organizations must continue to measure and improve quality metrics for PD, expand their focus beyond the sole provision of PD to holistic patient care, and initiate programs to reduce PD hospitalization rates and encourage physicians to consider the benefits of PD as an initial modality for appropriate patients. New and innovative strategies are needed to address the main reasons for PD technique failure, improve the connectivity of the patient in the home, leverage home biometric data to improve overall outcomes, and develop PD cycler devices that lower patient treatment burden and reduce both treatment fatigue and treatment-dependent complications. © 2017 Wiley Periodicals, Inc.

    Full Text Available Peritonitis caused by Staphylococcus aureus is a serious complication of peritoneal dialysis (PD, which is associated with poor outcome and high PD failure rates. We reviewed the records of 62 S. aureus peritonitis episodes that occurred between 1996 and 2010 in the dialysis unit of a single university hospital and evaluated the host and bacterial factors influencing peritonitis outcome. Peritonitis incidence was calculated for three subsequent 5-year periods and compared using a Poisson regression model. The production of biofilm, enzymes, and toxins was evaluated. Oxacillin resistance was evaluated based on minimum inhibitory concentration and presence of the mecA gene. Logistic regression was used for the analysis of demographic, clinical, and microbiological factors influencing peritonitis outcome. Resolution and death rates were compared with 117 contemporary coagulase-negative staphylococcus (CoNS episodes. The incidence of S. aureus peritonitis declined significantly over time from 0.13 in 1996-2000 to 0.04 episodes/patient/year in 2006-2010 (p = 0.03. The oxacillin resistance rate was 11.3%. Toxin and enzyme production was expressive, except for enterotoxin D. Biofilm production was positive in 88.7% of strains. The presence of the mecA gene was associated with a higher frequency of fever and abdominal pain. The logistic regression model showed that diabetes mellitus (p = 0.009 and β-hemolysin production (p = 0.006 were independent predictors of non-resolution of infection. The probability of resolution was higher among patients aged 41 to 60 years than among those >60 years (p = 0.02. A trend to higher death rate was observed for S. aureus episodes (9.7% compared to CoNS episodes (2.5%, (p = 0.08, whereas resolution rates were similar. Despite the decline in incidence, S. aureus peritonitis remains a serious complication of PD that is associated with a high death rate. The outcome of this infection is negatively

    The pH of conventional peritoneal dialysis solution is normally in the range of 5.0 to 5.5, because acid has been added during the manufacturing process to prevent caramelization of dextrose during sterilization. We studied the effects of normalizing the pH of conventional peritoneal dialysis solution on superoxide production by normal human neutrophils. At a pH of 6.0, superoxide generation was 4.07 +/- 2.56 (SD) nanomoles per million cells. With normalization of pH to 7.4, superoxide production was 19.3 +/- 7.3 (p less than 0.001). The results suggest that the unphysiologic acidity of conventional peritoneal dialysis solution has deleterious consequences on neutrophil superoxide formation.

    Full Text Available In the past, peritoneal metastasis (PM was considered as a terminal stage of cancer. From the early 1990s, however, a new comprehensive treatment consisting of cytoreductive surgery and perioperative chemotherapy has been established to improve long-term survival for selected patients with PM. Among prognostic indicators after the treatment, completeness of cytoreduction is the most independent predictors of survival. However, peritoneal recurrence is a main cause of recurrence, even after complete cytoreduction. As a cause of peritoneal recurrence, small PM may be overlooked at the time of cytoreductive surgery (CRS, therefore, development of a new method to detect small PM is desired. Recently, photodynamic diagnosis (PDD was developed for detection of PM. The objectives of this review were to evaluate whether PDD using 5-aminolevulinic acid (ALA could improve detection of small PM.

    The significance of peritoneal dialysis in kidney replacement therapy is expected to increase, so it is important to reconsider glucose exposure to minimize the adverse effects. The first step was to develop biocompatible modern PD solutions to reduce the local and systemic adverse effects of current conventional glucose-based ones. According to the limited clinical experience, there are no clear data on better clinical outcome. Besides this there is a suspected theoretical correlation between development of encapsulating peritoneal sclerosis and chronic local irritation of peritoneal surface by glucose. The degree of actual systemic glycemic load can be evaluated by continuous tissue glucose monitoring, and cumulative damage can be measured by skin autofluorescence, however none of the methods have been extensively used in clinical practice. The early diagnosis of cardiovascular diseases is therefore of also paramount importance. Selecting the therapeutic steps including diabetological aspects, we must constantly strive to improve the life quality. Orv Hetil. 2017; 158(43): 1708-1714.

    The management of volume in patients with diabetes on peritoneal dialysis is affected by several factors, including the degree of residual renal function, peritoneal membrane small-solute transport, salt and water intake, blood sugar control, comorbidity, and nutritional status. It requires sequential evaluation of volume status and adjustment of the peritoneal dialysis prescription on the basis of assessments of membrane function and alterations in urine volume. Steps should be taken to preserve residual renal function for as long as possible. Ultimately, in patients who have become anuric and have developed ultrafiltration failure, timely transfer to hemodialysis may be necessary, requiring discussion and planning with the patient.

    Currently, chronic kidney disease (CKD) is a global health problem. Considering the impaired immunity of CKD patients, the relevance of infection in peritoneal dialysis (PD), and the increased prevalence of parasites in CKD patients, protozoa colonization was evaluated in PD effluent from CKD patients undergoing PD. Overnight PD effluent was obtained from 49 asymptomatic stable PD patients. Protozoa analysis was performed microscopically by searching cysts and trophozoites in direct wet mount of PD effluent and after staining smears. Protozoa were found in PD effluent of 10.2% of evaluated PD patients, namely Blastocystis hominis, in 2 patients, and Entamoeba sp., Giardia sp., and Endolimax nana in the other 3 patients, respectively. None of these patients presented clinical signs or symptoms of peritonitis at the time of protozoa screening. Our results demonstrate that PD effluent may be susceptible to asymptomatic protozoa colonization. The clinical impact of this finding should be further investigated.

    Full Text Available Spontaneous bacterial peritonitis is a severe and life-threatening complication in patients with ascites caused by advanced liver disease. The organisms most commonly involved are coliform bacteria and third-generation cephalosporins are the empiric antibiotics of choice. This is an uncommon case of spontaneous bacterial peritonitis caused by Listeria monocytogenes in a female patient with liver cirrhosis from autoimmune hepatitis. She did not improve with ceftriaxone and her course was complicated by hepatic encephalopathy, seizures and multi-organ failure. This case emphasizes that a high index of suspicion should be maintained for timely diagnosis and treatment. Listerial peritonitis should be suspected in patients with end-stage liver disease and inadequate response to conventional antibiotics within 48–72 h. Ampicillin/sulbactam should be initiated while awaiting results of ascitic fluid or blood culture.

    Introduction To evaluate the impact of serum and peritoneal levels of tumour markers on peritoneal carcinomatosis and survival in gastric adenocarcinoma. Materials and methods Patients with gastric adenocarcinoma were evaluated with regard to serum and peritoneal carcinoembryonic antigen (CEA) and CA19-9. Numeric values and groupings based on serum and peritoneal cutoff values were used. Development of peritoneal carcinomatosis, including positive washing cytology, was regarded as main outcome. Gastric cancer outcomes as disease free and overall survival were analysed. Results There were 67 patients with a mean age of 60 ± 11 years. Positive peritoneal washing cytology was significantly associated with serum CA19-9 and high serum CA 19-9 group (P = 0.033 and P = 0.011, respectively). High peritoneal CEA was shown to be significantly associated with peritoneal carcinomatosis (P = 0.032). After a median follow up of 17 months, 48 patients (71.7%) were alive. Patients with peritoneal carcinomatosis showed significant poorer prognosis as shown by overall survival rate of 28.6%. Only serum CEA was significantly associated with lower disease free and overall survival (P = 0.002 and P = 0.001, respectively). Discussion and conclusion Serum CEA is shown to be significantly associated with poor prognosis for gastric cancer patients. Serum level of CA19-9 and high peritoneal CEA levels are significant predictors for positive peritoneal washing cytology and the development of peritoneal carcinomatosis, respectively. Therefore, the possible impact of serum and peritoneal tumor markers especially on the staging and prognosis of gastric cancer remains to be clarified by future studies.

    Full Text Available Encapsulating peritoneal sclerosis (EPS is a life threatening complication of peritoneal dialysis (PD. Podoplanin is a glycoprotein expressed by mesothelial cells, lymphatic endothelial cells, and myofibroblasts in peritoneal biopsies from patients with EPS. To evaluate podoplanin as a marker of EPS we measured podoplanin mRNA and described the morphological patterns of podoplanin-positive cells in EPS. Included were 20 peritoneal biopsies from patients with the diagnosis of EPS (n = 5, patients on PD without signs of EPS (n = 5, and control patients (uremic patients not on PD, n = 5, non-uremic patients n = 5. EPS patient biopsies revealed significantly elevated levels of podoplanin mRNA (p<0.05. In 24 peritoneal biopsies from patients with EPS, podoplanin and smooth muscle actin (SMA were localized by immunohistochemistry. Four patterns of podoplanin distribution were distinguishable. The most common pattern (8 of 24 consisted of organized, longitudinal layers of podoplanin-positive cells and vessels in the fibrotic zone ("organized" pattern. 7 of 24 biopsies demonstrated a diffuse distribution of podoplanin-positive cells, accompanied by occasional, dense clusters of podoplanin-positive cells. Five biopsies exhibited a mixed pattern, with some diffuse areas and some organized areas ("mixed". These contained cuboidal podoplanin-positive cells within SMA-negative epithelial structures embedded in extracellular matrix. Less frequently observed was the complete absence of, or only focal accumulations of podoplanin-positive fibroblasts outside of lymphatic vessels (podoplanin "low", 4 of 24 biopsies. Patients in this group exhibited a lower index of systemic inflammation and a longer symptomatic period than in EPS patients with biopsies of the "mixed" type (p<0.05. In summary we confirm the increased expression of podoplanin in EPS, and distinguish EPS biopsies according to different podoplanin expression patterns which are associated with

    For patients with end-stage kidney disease unable to receive a kidney transplant, replacement of kidney function with dialysis is necessary to extend life. Peritoneal dialysis (PD) and hemodialysis (HD) are the two major forms of dialysis therapy. HD involves the passage of blood via an extracorporeal circuit whereby removal of small solutes, toxins, and water is achieved across a synthetic, semipermeable dialysis membrane. In contrast, in PD, the dialysis membrane is the highly vascularized internal lining of the peritoneal cavity. Intraperitoneal installation of hypertonic high glucose PD solution creates a transmembrane osmotic and diffusive gradient that facilitates water removal [ultrafiltration (UF)], convection, and diffusion of uremic toxins. Insight into the physiology of solute and water transport across the peritoneal membrane has been enhanced by the proposal of the ''three-pore model'' of peritoneal membrane transport. Transport characteristics and UF capacity of the peritoneal membrane vary among individuals, and deleterious changes in the membrane may ensue over time. The degree to which these changes are a direct consequence of the type and composition of currently available PD solutions, recurrent infectious episodes, genetic differences among individuals, or a combination thereof is the subject of intense study. Adverse consequences resulting from the systemic and local metabolic effects of intraperitoneal glucose exposure, infection of the PD fluid, PD catheter dysfunction, and patient burnout from self-care often limit the long-term success of the therapy. Research aimed at addressing these challenges will examine the use of more biocompatible PD solutions and strategies aimed at attenuating progressive peritoneal membrane injury.

  18. US anatomy of the great peritoneal cavity and its recesses

    The peritoneum of the great abdominal cavity and its recesses are a blind radiographical area which can however be easily outlined by US when it contains fluid. The anatomical study of these usually virtual cavities represent the purpose of this paper. The natural contrast of the peritoneal fluid as amplified by the mechanical effect produced by an adequate amount of fluid, allows a clear visualization of the anatomy of various peritoneal structures in either upper (subphrenic, subhepatic, lesser sac, etc.) or lower (pelvic) areas. The sovramesocolic and the infracolic compartments are in comunication through the two external paracolic gutters which are the main passageways for the fluids between upper and lower compartments. In fact, peritoneal fluids are in constant movement due to different factors, such as gravity, statics, which causes the peritoneal fluids to flow into the lowest part of the peritoneal cavity, and hydrostatic pressure. Pressure differences are thought to convey fluids from various sites of the abdomen into different areas. In the lower abdomen, pressure is 3 times as much as in the upper abdomen, which causes the fluids to move into the subhepatic and subphrenic regions. The redistribution of fluids can be influenced by particular anatomical causes. The phrenicocolic ligament, e.g., is a barrier to the advancing of fluds along the left paracolic gutter, which makes the right paracolic gutter the main passageway for the fluids. This pattern explains why abscesses are more frequent in the right than in the upper left abdominal regions. Another example in the tiny Winslow opening, which does not allow inflammatory material to pass into the lesser sac in case of inflammatory processes of the great peritoneal cavity and viceversa. Moreover, pointing out fluid collections and abscesses is important, since an early diagnosis and a topografic map are essential order to plan treatment

    Peritoneal dialysis (PD) contributes to restore acid-base homeostasis in patients with end-stage renal disease. The transport pathways for buffers and carbon dioxide (CO2) across the peritoneal membrane remain poorly understood. Combining well-established PD protocols, whole-body plethysmography and renal function studies in mice, we investigated molecular mechanisms of acid-base regulation in PD, including the potential role of the water channel aquaporin-1 (AQP1). After instillation in peritoneal cavity, the pH of acidic dialysis solutions increased within minutes to rapidly equilibrate with blood pH, whereas the neutral pH of biocompatible solutions remained constant. Predictions from the three-pore model of peritoneal transport suggested that local production of HCO3- accounts at least in part for the changes in intraperitoneal pH observed with acidic solutions. Carbonic anhydrase (CA) isoforms were evidenced in the peritoneal membrane and their inhibition with acetazolamide significantly decreased local production of HCO3- and delayed changes in intraperitoneal pH. On the contrary, genetic deletion of AQP1 had no effect on peritoneal transport of buffers and diffusion of CO2. Besides intraperitoneal modifications, the use of acidic dialysis solutions enhanced acid excretion both at pulmonary and renal levels. These findings suggest that changes in intraperitoneal pH during PD are mediated by bidirectional buffer transport and by CA-mediated production of HCO3- in the membrane. The use of acidic solutions enhances acid excretion through respiratory and renal responses, which should be considered in patients with renal failure. © The Author 2017.

    Lethal enterococcal peritonitis in mice was used to compare trimethoprim-sulfamethoxazole (TMP-SMX) therapy with ampicillin therapy. Peritoneal fluid showed a 10(3)-CFU decrease in enterococci with ampicillin compared with TMP-SMX. Mortality of the untreated mice was 100%, compared with 40% for ampicillin and 95% for TMP-SMX, despite adequately measured levels in serum and peritoneal fluid.

    Full Text Available Background and aims: ERCP during pregnancy is always challenging for the entire team performing the endoscopic intervention. In this study techniques and different interventional aspects used at several centres about the clinical experience on ERCP in pregnant women are analyzed. Patients and methods: the practice on ERCP in pregnant women in six centers during a period of ten years is reported. Results: eleven patients were included in the study. Mean age was 30.6 years. Indication for ERCP was always symptomatic common bile duct stone (CBDS disease. Before the procedure abdominal ultrasound was performed at all times and magnetic resonance cholangiopancreatography in four occasions. Conscious sedation by means of midazolam and fentanyl or meperidine was applied. Sphincterotomes and guidewires were used for bilary cannulation. Sometimes, rapid exchange platforms with short-length guidewires controlled by the same endoscopist were employed. Biliary cannulation was confirmed in 9 occasions by bile aspiration. In five procedures, a mean of 30 seconds of fluoroscopy was used, both to verify cannulation and to corroborate complete CBDS clearance. These patients had the pelvic zone protected with a lead shield and radiation dose was measured. Ten biliary sphincterotomies were performed followed by CBDS extraction. Two plastic stents were inserted. Relief of biliary obstruction was attained in all circumstances. Only one patient had hyperamylasemia after ERCP. All pregnant women had healthy foetuses with normal deliveries. Conclusions: with experience, ERCP appears to be a safe technique during pregnancy. With simple measures fluoroscopic time can be diminished or even abolished. It seems that ERCP during pregnancy is underused in our working areas, although it has shown to be a useful technique for relieving biliary obstruction.Antecedentes y objetivos: la CPRE realizada durante el embarazo constituye siempre un reto para todo el equipo que participa

    We report the imaging findings of two recent cases of primary bacterial peritonitis in otherwise healthy children with a clinical presentation mimicking acute appendicitis. Primary bacterial peritonitis is rare in the absence of underlying systemic disease. Although it has been described in the pediatric literature, the imaging findings have not been described in the radiological literature to the best of our knowledge. With imaging playing an increasing role in the evaluation of appendicitis in children, it is important for the radiologist to be familiar with this inflammatory process. (orig.)

    Full Text Available Angiotensin-converting enzyme (ACE inhibitors are a significant group of drugs that are primarily used in the treatment of hypertension and congestive heart failure. Even though they belong to the same group of drugs and have similar efficacy, ACE inhibitors exhibit different pharmacological characteristics. The lipophilicity is one of the most important properties of biologically active substances. It influences their absorption, distribution, tissue penetration, action, elimination. In this paper, the elimination of ACE inhibitors by peritoneal dialisate in patients on peritoneal dialysis was investigated. The influence of ACE inhibitors' hydrophibicity in this way of elimination was discussed.

    Full Text Available Meconium peritonitis pseudo-cyst is very rare. Its perinatal management is controversial and can be associated with increased fetomaternal morbidity and mortality. A 34-week gestation infant with large meconium peritonitis pseudo-cyst, detected by intrapartum fetal ultrasound study, had abnormally increased ratio of fetal abdominal circumference to head circumference. Intrapartum aspiration of the pseudo-cyst was performed and was followed by a smooth vaginal delivery. The postnatal course of the baby showed that early laparotomy was essential for stabilisation of the infant's general condition.

    Valvular cardiomyopathy can present a diagnostic challenge in the absence of overt cardiac symptoms. This report describes the case of a 46-year-old woman who presented with acute peritonitis associated with vomiting and abdominal distension. Subsequent abdominal computed tomography and ultrasound revealed bibasal pleural effusions, ascites, and normal ovaries. An echocardiogram revealed that all cardiac chambers were dilated with a global decrease in contractility and severe mitral, tricuspid, and aortic regurgitation. A diagnosis of cardiomyopathy with acute heart failure, secondary to valvular heart disease, was secured. Acute peritonitis as the presenting feature of valvular cardiomyopathy is a rare clinical entity.

    A point-of-care and home-care lab-on-a-chip (LoC) system that integrates a microfluidic spiral device as a concentrator with an optical-coding device as a cell enumerator is demonstrated. The LoC system enumerates white blood cells from dialysis effluent of patients receiving peritoneal dialysis. The preliminary results show that the white blood cell counts from our system agree well with the results from commercial flow cytometers. The LoC system can potentially bring significant benefits to end stage renal disease (ESRD) patients that are on peritoneal dialysis (PD).

    The use of automated peritoneal dialysis (APD) is increasing compared to continuous ambulatory peritoneal dialysis (CAPD). Surprisingly, little data about health benefits and cost of APD exist, and virtually no information comparing the cost-utility between CAPD and APD is available. We undertook this study to evaluate and compare the health-related quality of life (HRQOL) and cost-utility indexes in patients on CAPD vs. This was a prospective cohort of patients initiating dialysis (2008-2009). Two questionnaires were self-administered: European Research Questionnaire Quality of Life (EQ-5D) and Kidney Disease Quality of Life (short form, KDQOL-SF, Rand, Santa Monica, CA). Direct medical costs (DMC) were determined from the health provider perspective including the following medical resource utilization: outpatient clinic/emergency care, dialysis procedures, medications, laboratory tests, hospitalization, and surgery. Cost-utility indexes were calculated dividing total mean cost by indicators of the HRQOL. One hundred twenty-three patients were evaluated: 77 on CAPD and 46 on APD. Results of the EQ-5D and KDQOL-SF questionnaires were significantly better in APD compared to the CAPD group. Main costs in both APD and CAPD were attributed to hospitalization and dialysis procedures followed by medication and surgery. Outpatient clinic visits and laboratory tests were significantly more costly in CAPD than in APD, whereas dialysis procedures were more expensive in the latter. Cost-utility indexes were significantly better in APD compared to CAPD. A significant cost-utility advantage of APD vs. CAPD was observed. The annual DMC per-patient were not different between groups but the HRQOL was better in the APD compared to the CAPD group. Copyright © 2013 IMSS. Published by Elsevier Inc. All rights reserved.

    Peritoneal dialysis (PD) is a form of renal replacement treatment, which employs the peritoneal membrane (PM) to eliminate toxins that cannot be removed by the kidney. The procedure itself, however, contributes to the loss of the PM ultrafiltration capacity (UFC), leading consequently to the technique malfunction. β-blockers have been considered deleterious for PM due to their association with loss of UFC and induction of fibrosis. Herein we analyzed the effects of Nebivolol, a new generation of β1-blocker, on PM alterations induced by PD fluids (PDF).In vitro: We found that mesothelial cells (MCs) express β1-adrenergic receptor. MCs were treated with TGF-β to induce mesothelial-to-mesenchymal transition (MMT) and co-treated with Nebivolol. Nebivolol reversed the TGF-β effects, decreasing extracellular matrix synthesis, and improved the fibrinolytic capacity, decreasing plasminogen activator inhibitor-1 (PAI-1) and increasing tissue-type plasminogen activator (tPA) supernatant levels. Moreover, Nebivolol partially inhibited MMT and decreased vascular endothelial growth factor (VEGF) and IL-6 levels in supernatants.In vivo: Twenty-one C57BL/6 mice were divided into 3 groups. Control group carried a catheter without PDF infusion. Study group received intraperitoneally PDF and oral Nebivolol during 30 days. PDF group received PDF alone. Nebivolol maintained the UFC and reduced PM thickness, MMT and angiogenesis promoted by PDF. It also improved the fibrinolytic capacity in PD effluents decreasing PAI-1 and IL-8 and increased tPA levels. Nebivolol protects PM from PDF-induced damage, promoting anti-fibrotic, anti-angiogenic, anti-inflammatory and pro-fibrinolytic effects.

    Continuous ambulatory peritoneal dialysis (CAPD) is a well established method of treating end stage renal failure, and is commonly used as an alternative to hemodialysis. Several complications have been observed. These include catheter malfunction, abdominal and inguinal hernia, and peritonitis. A relatively frequent complication is swelling of external genitalia, due to bowel fluid passing through a patent processus vaginalis. Special diagnostic procedures are necessary to determine the nature of the abnormality and to guide the surgical correction. We reported two cases of patent processus vaginalis in patient on CAPD proved by radionuclide peritonea scintiscan using {sup 99m}Tc-tin colloid.

    Terminal-stage patients on peritoneal dialysis (PD) are often transferred to haemodialysis as they are unable to perform the dialysis technique themselves since their functional capacities are reduced. We present our experience with five patients on PD with a shortterm life-threatening condition, whose treatment was shared by primary care units and who were treated with a PD modality adapted to their circumstances, which we call Palliative Peritoneal Dialysis.

    Full Text Available Peritonitis is one of the major problems confronting the surgeons in day to day practice. Despite many advances in understanding pathophysiology, mortality rate of diffuse suppurative peritonitis remains high. A prospective study, with prior institutional ethics committee approval, involving 100 patients of perforative peritonitis is done to assess the vari ous prognostic factors in management of generalized peritonitis. Role of age, gender, duration, type of perforation, associated systemic factors are studied in relation to morbidity and mortality in the outcome of management of peritonitis. Elderly age, il eal perforations, delay in presentation of more than 24 hours and associated shock on day one are found to have bad prognosis

    Peritoneal dialysis (PD)-related peritonitis remains an important complication in PD patients, potentially causing technique failure and influencing patient outcome. To date, no comprehensive study in the Taiwanese PD population has used a time-dependent statistical method to analyze the factors associated with PD-related peritonitis. Our single-center retrospective cohort study, conducted in southern Taiwan between February 1999 and July 2010, used time-dependent statistical methods to analyze the factors associated with PD-related peritonitis. The study recruited 404 PD patients for analysis, 150 of whom experienced at least 1 episode of peritonitis during the follow-up period. The incidence rate of peritonitis was highest during the first 6 months after PD start. A comparison of patients in the two groups (peritonitis vs null-peritonitis) by univariate analysis showed that the peritonitis group included fewer men (p = 0.048) and more patients of older age (≥65 years, p = 0.049). In addition, patients who had never received compulsory education showed a statistically higher incidence of PD-related peritonitis in the univariate analysis (p = 0.04). A proportional hazards model identified education level (less than elementary school vs any higher education level) as having an independent association with PD-related peritonitis [hazard ratio (HR): 1.45; 95% confidence interval (CI): 1.01 to 2.06; p = 0.045). Comorbidities measured using the Charlson comorbidity index (score >2 vs ≤2) showed borderline statistical significance (HR: 1.44; 95% CI: 1.00 to 2.13; p = 0.053). A lower education level is a major risk factor for PD-related peritonitis independent of age, sex, hypoalbuminemia, and comorbidities. Our study emphasizes that a comprehensive PD education program is crucial for PD patients with a lower education level.

    The aim of this study was to assess laparoscopic lavage in patients with acute diverticulitis. In recent times, laparoscopic peritoneal lavage has been considered a therapeutic alternative to standard resection procedures. In Hinchey III diverticulitis there is the possibility of avoiding ostomies or resection procedures. This retrospective study was conducted in a single-care institution. Patients requiring emergency surgery for perforated diverticulitis and generalized peritonitis between March 2011 and May 2014 were identified from a prospective database. Seventy-two patients underwent surgery for diverticulitis. Forty-three patients presented with generalized peritonitis (Hinchey III) and 29 with gross fecal contamination (Hinchey IV). From the Hinchey III group, 17 patients (39.5%), with a median age of 56.8 years, were selected to undergo peritoneal lavage.Postoperative length of stay was 4.2 days, the rate of minor complications was 35%, that of major complications was 0%, and mortality rate was 0%. Over a median follow-up of 24.6 months none required reoperation. The number of patients selected for laparoscopic lavage in the management of perforated diverticulitis is increasing as it provides an alternative to Hartmann's procedure in emergency cases. This approach should be considered suitable for patients without important comorbidities, and only in centers experienced in laparoscopic surgery. It reduces the length of hospital stay. Morbidity and mortality are lower than in those in whom resection was considered necessary. Longer follow-up and results of other trials will be necessary to draw an adequate conclusion.

    2012-01-01

    Peritoneal dialysis (PD) is the treatment modality of choice in pediatric CKD5D patients awaiting renal transplantation. Facing many decades of renal replacement therapy long term preservation of peritoneal membrane function is of particular importance in this patient group. Whereas conventional PD fluids induce severe morphological and functional alterations of the peritoneal membrane within a few years, reduction of glucose degradation product content by multichamber systems, replacement of glucose by icodextrin and amino acids, and of lactate by bicarbonate at a neutral to physiological pH are expected to preserve peritoneal membrane integrity. Based on numerous in vitro, experimental and clinical studies, the European Pediatric Dialysis Working Group recommended the use of low glucose degradation product solutions whenever possible. Icodextrin is considered a useful option, in particular in children with sodium and water overload, even though infants may absorb higher amounts of icodextrin and achieve less ultrafiltration. The concept of amino acid-based PD fluids is intriguing, but pediatric benefits are insufficiently described and cannot replace tube feeding in malnourished children. Bicarbonate-based PD fluids better control metabolic acidosis and have been recommended in children with acute kidney injury and impaired lactate metabolism. This review discusses the scientific evidence and potential advantages of PD solutions with an improved biocompatibility profile, with a particular focus on pediatric studies. Copyright © 2012 S.
