    According to the National Registry of Renal Replacement Therapy (RRT), the incidence of chronic kidney disease (end-stage renal disease) and the need of RRT have declined in the last decade renal. One of the reasons for this tendency certainly is transplantation as the best choice. However, transplant procedure has limitations in elderly patients due to the number of comorbidities. This study was designed as retrospective analysis of outcomes in patients treated with peritoneal dialysis for a period of eleven years. Patients were divided into those who had been assisted or unassisted. Out of 100 patients treated with peritoneal dialysis (PD), 77 completed the treatment, including 26 assisted and 51 unassisted patients. Peritonitis was recorded in 20 assisted and 26 unassisted patients. Peritonitis was more common in unassisted patients, who were more frequently lost from PD. Assisted PD could be a good and safe choice of RRT in this special group of patients.

    Full Text Available Introduction: Chronic kidney disease in Brunei Darussalam is a growing problem. The number of patients reaching end stage kidney failure has increased dramatically in the last ten years. Currently, most are managed with haemodialysis while a smaller proportion is managed with continuous ambulatory peritoneal dialysis (CAPD. Automated peritoneal dialysis (APD is a form of peritoneal dialysis and has been used in Brunei Darussalam since May 2008. Materials and Methods: Eight patients participated in this prospective clinical trial. As all APD patients were previously on CAPD, comparisons are made between the outcomes of APD against CAPD. Results: The median and mean age of APD patients were 42 and 45.5 ± 12.73 years respectively. After switching to APD, the serum haemoglobin and albumin improved from 10.56 ± 1.95 gm/L and 27.88 ± 7.71 gm/dL to 12.26 ± 1.82 gm/L and 33.63 ± 6.89 gm/dL respectively (p values <0.05. This corresponded to improvements in seven (87.5% and six (75% patients respectively in both parameters. Erythropoietin requirement was reduced in six (75% patients, including three (37.5% patients who were able to stop erythropoietin completely. There was no peritonitis encountered. All patients reported improved quality of life with better sleep, appetite and general well-being. Conclusions: Our study showed that APD was as good as CAPD with improvement seen in both laboratory and quality of life parameters. There was also reduction in erythropoietin requirement. Based on these findings, we will actively encourage and promote APD usage as oppose to CAPD usage in our population.

    Full Text Available Abstract Introduction Presentations of abdominal pain in patients on peritoneal dialysis deserve maximal attention and careful differential diagnosis on admittance to medical care. In this case report a gangrenous appendicitis in a patient on automated peritoneal dialysis is presented. Case presentation We report the case of a 38-year-old Caucasian man with end-stage renal disease who was on automated peritoneal dialysis and developed acute abdominal pain and cloudy peritoneal dialysate. Negative microbiological cultures of the peritoneal dialysis fluid and an abdominal ultrasonography misleadingly led to a diagnosis of culture negative peritonitis. It was decided to remove the peritoneal catheter but the clinical situation of the patient did not improve. An explorative laparotomy was then carried out; diffuse peritonitis and gangrenous appendicitis were found. An appendectomy was performed. Myocardial infarction and sepsis developed, and the outcome was fatal. Conclusion A peritoneal dialysis patient with abdominal pain that persists for more than 48 hours after the usual antibiotic protocol for peritoneal dialysis-related peritonitis should immediately alert the physician to the possibility of peritonitis caused by intra-abdominal pathology. Not only peritoneal catheter removal is indicated in patients whose clinical features worsen or fail to resolve with the established intra-peritoneal antibiotic therapy but, after 72 hours, an early laparoscopy should be done and in a case of correct indication (intra-abdominal pathology an early explorative laparotomy.

  6. Automated Peritoneal Dialysis Is Associated with Better Survival Rates Compared to Continuous Ambulatory Peritoneal Dialysis: A Propensity Score Matching Analysis.

    Gabriela de Carvalho Beduschi

    Full Text Available The impact of peritoneal dialysis modality on patient survival and peritonitis rates is not fully understood, and no large-scale randomized clinical trial (RCT is available. In the absence of a RCT, the use of an advanced matching procedure to reduce selection bias in large cohort studies may be the best approach. The aim of this study is to compare automated peritoneal dialysis (APD and continuous ambulatory peritoneal dialysis (CAPD according to peritonitis risk, technique failure and patient survival in a large nation-wide PD cohort.This is a prospective cohort study that included all incident PD patients with at least 90 days of PD recruited in the BRAZPD study. All patients who were treated exclusively with either APD or CAPD were matched for 15 different covariates using a propensity score calculated with the nearest neighbor method. Clinical outcomes analyzed were overall mortality, technique failure and time to first peritonitis. For all analysis we also adjusted the curves for the presence of competing risks with the Fine and Gray analysis.After the matching procedure, 2,890 patients were included in the analysis (1,445 in each group. Baseline characteristics were similar for all covariates including: age, diabetes, BMI, Center-experience, coronary artery disease, cancer, literacy, hypertension, race, previous HD, gender, pre-dialysis care, family income, peripheral artery disease and year of starting PD. Mortality rate was higher in CAPD patients (SHR1.44 CI95%1.21-1.71 compared to APD, but no difference was observed for technique failure (SHR0.83 CI95%0.69-1.02 nor for time till the first peritonitis episode (SHR0.96 CI95%0.93-1.11.In the first large PD cohort study with groups balanced for several covariates using propensity score matching, PD modality was not associated with differences in neither time to first peritonitis nor in technique failure. Nevertheless, patient survival was significantly better in APD patients.

    2013-06-01

    The number of elderly patients with end stage renal disease is constantly increasing. Conventional hämodiaylsis as the mainstay of renal replacement therapy is often poorly tolerated by frail eldery patients with multiple comorbidities. Although many of these patients would prefer a home based dialysis treatment, the number of elderly patients using peritoneal dialysis (PD) is still low. Impaired physical and cognitive function often generates insurmountable barriers for self care peritoneal dialysis. Assisted peritoneal dialysis can overcome many of these barriers and give elderly patients the ability of a renal replacement therapy in their own homes respecting their needs. PMID:23797681

    Sleep disorders for patients on dialysis are significant causes of a poorer quality of life and increased morbidity and mortality. No study has evaluated patients undergoing automated peritoneal dialysis (APD) to assess their sleep disorders compared to hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD). A total of 166 clinically stable patients who had been on dialysis for at least 3 months were randomly selected for the study and divided into HD, CAPD or APD. Socio-demographic, clinical and laboratory parameters and self-administered questionnaires were collected for the investigation of insomnia, restless legs syndrome (RLS), bruxism, rapid eye movement sleep behavior disorder, excessive daytime sleepiness (EDS), obstructive sleep apnea syndrome (OSAS), sleepwalking, sleep hygiene, depression and anxiety. Insomnia was detected in more than 80 % of patients on the three modalities. OSAS was lower for patients on HD (36 %) than on CAPD (65 %) (p sleepwalking, sleep hygiene, depression or anxiety. ESRD patients undergoing any one of the three dialysis modalities studied had a high prevalence of sleep disorders. Patients on HD had a lower proportion of OSAS than those on CAPD and APD, which is most likely attributed to their lower body mass indices. The possible causes of higher RLS rates in APD patients have not been established. PMID:25358390

    The increasing amount of data in industrial automation systems overburdens the user in process control and diagnosis tasks. One possibility to cope with these challenges consists of using smart assistance systems that automatically monitor and optimize processes. This article deals with aspects of data-driven assistance systems such as assistance functions, process models and data acquisition. The paper describes novel approaches for self-diagnosis and self-optimization, and shows how these assistance functions can be integrated in different industrial environments. The considered assistance functions are based on process models that are automatically learned from process data. Fault detection and isolation is based on the comparison of observations of the real system with predictions obtained by application of the process models. The process models are further employed for energy efficiency optimization of industrial processes. Experimental results are presented for fault detection and energy efficiency optimization of a drive system.

    The paper presents the kinematic and dynamic analysis of a power-shift automated manual transmission (AMT) characterised by a wet clutch, called assist clutch (ACL), replacing the fifth gear synchroniser. This torque assist mechanism becomes a torque transfer path during gearshifts, in order to overcome a typical dynamic problem of the AMTs, that is the driving force interruption. The mean power contributions during gearshifts are computed for different engine and ACL interventions, thus allowing to draw considerations useful for developing the control algorithms. The simulation results prove the advantages in terms of gearshift quality and ride comfort of the analysed transmission.

  17. Comparison of peritoneal free gastric cancer cells' detecting rates between laparoscopically assisted and open radical gastrectomy

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective: To compare laparoscopic gastrectomy and conventional surgery on the dissemination and seeding of tumor cells. Methods:Intraoperative peritoneal lavage cytologic examination was performed in 65 patients with gastric cancer, during laparoscopic gastrectomy (n=34) and conventional surgery (n=31). Cytology was examined twice, immediately after opening the peritoneal cavity and just before closing the abdomen. Saline was poured into the peritoneal cavity, and 100 ml fluid was retrieved after irrigation. Laparoscopic instruments were lavaged after surgery with 100 ml saline. Carbon dioxide (CO2) was derived through the trocar side orifice after pneumoperitoneum during laparoscopic gastrectomy and filtered through 100 ml saline. Cytologic examination of the filtrate was performed after the filtration process. Results: The incidence of positive cytology during laparoscopic surgery was 32.26% in the preoperative lavage and 22.58% in the postoperative lavage. The incidence of positive cytology during conventional surgery was 41.18% before lavage and 26.47% after lavage. Only one positive cytology was detected in the CO2 filtrate gas. The incidence of positive cytology in the lavage of the instruments during laparoscopic surgery was 6.45%. Conclusion: During gastric laparoscopic surgery, CO2 pneumoperitoneum does not affect tumor cell dissemination and seeding. In this study, laparoscopic techniques used in gastric cancer surgery were not associated with a higher risk for intraperitoneal dissemination of cancer cells than the conventional surgery.

    Segmentation of an ultrasound image into functional tissues is of great importance to clinical diagnosis of breast cancer. However, many studies are found to segment only the mass of interest and not all major tissues. Differences and inconsistencies in ultrasound interpretation call for an automated segmentation method to make results operator-independent. Furthermore, manual segmentation of entire three-dimensional (3D) ultrasound volumes is time-consuming, resource-intensive, and clinically impractical. Here, we propose an automated algorithm to segment 3D ultrasound volumes into three major tissue types: cyst/mass, fatty tissue, and fibro-glandular tissue. To test its efficacy and consistency, the proposed automated method was employed on a database of 21 cases of whole breast ultrasound. Experimental results show that our proposed method not only distinguishes fat and non-fat tissues correctly, but performs well in classifying cyst/mass. Comparison of density assessment between the automated method and manual segmentation demonstrates good consistency with an accuracy of 85.7%. Quantitative comparison of corresponding tissue volumes, which uses overlap ratio, gives an average similarity of 74.54%, consistent with values seen in MRI brain segmentations. Thus, our proposed method exhibits great potential as an automated approach to segment 3D whole breast ultrasound volumes into functionally distinct tissues that may help to correct ultrasound speed of sound aberrations and assist in density based prognosis of breast cancer.

  6. Peritoneal carcinomatosis

    International Nuclear Information System (INIS)

    The peritoneum is a mesothelial lining of the abdominal cavity (parietal) and intraperitoneal viscera (visceral). The cavity contains a small amount of fluid, which circulates from cephalad to caudal to cephalad, influenced by negative pressure under the diaphragm during exhalation, gravity, and bowel peristalsis. Peritoneal reflections and mesenteries divide the cavity into various compartments (supramesocolic, inframesocolic, and pelvis). These reflections support the peritoneal organs and provide vascular and nervous connections while within the cavity they influence pathway of intraperitoneal fluid circulation. Capillary force over convex surfaces influence stasis of fluid and promotes peritoneal seeding; thus, there are numerous areas in which peritoneal masses are seen more commonly. These areas include the undersurface of the diaphragm (negative pressure and capillary force), the omentum (bathed in fluid), the right lower quadrant (oblique course from left superior to right inferior of the small bowel mesentery), the left lower quadrant (transverse course of the sigmoid), and the pelvis (gravity). Peritoneal carcinomatosis may be either primary (mesothelioma) or metastatic. The mode of spread is by direct invasion, lymphatic permeation, peritoneal seeding or hematogenous. The imaging patterns include fibronodular stranding, nodules, plaques, and masses. Mesenteric thickening may produce pleated or stellate patterns. Spiral CT is the most useful modality in diagnosis and follow-up of peritoneal tumors. (orig.)

    In this paper, a new approach to planetary mission design is described which automates the search for gravity-assist trajectories. This method finds all conic solutions given a range of launch dates, a range of launch energies and a set of target planets. The new design tool is applied to the problems of finding multiple encounter trajectories to the outer planets and Venus gravity-assist trajectories to Mars. The last four-planet grand tour opportunity (until the year 2153) is identified. It requires an earth launch in 1996 and encounters Jupiter, Uranus, Neptune, and Pluto. Venus gravity-assist trajectories to Mars for the 30 year period 1995-2024 are examined. It is shown that in many cases these trajectories require less launch energy to reach Mars than direct ballistic trajectories.

  8. Peritoneal mesothelioma

    International Nuclear Information System (INIS)

    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.

    We report a case of relapsing peritonitis in a 33-year-old woman on automated peritoneal dialysis. End-stage renal disease was secondary to systemic lupus erythematosus complicated with lupus nephritis. The organism isolated was Brevibacterium casei that was not readily identified, delaying appropriate management with an extended antibiotic course. Definite management of B casei peritonitis was peritoneal dialysis catheter removal. PMID:24648477

    Here the authors report a case of refractory peritonitis leading to multiple hospitalizations and the loss of peritoneal dialysis access in a patient on automated peritoneal dialysis, caused by Asaia bogorensis, a bacterium not previously described as a human pathogen. This organism was identified by sequence analysis of the 16S ribosomal RNA gene. Unusual microbial agents may cause peritonitis, and molecular microbiological techniques are important tools for identifying these agents.

    Full Text Available OBJECTIVE: Peritonitis is the most important complication of peritoneal dialysis (PD. We evaluated the incidence of peritonitis, active microorganisms and their susceptibility profile and determine prognosis. MATERIAL and METHODS: One hundred fifty three PD patients were evaluated for aetiology, drug usage, accompanying disease, type, duration and personal preference for PD, care-giver, protein catabolic rate (PCR, residual urine volume, ultrafiltration volume, type of peritoneal membrane transport and baseline laboratory values. RESULTS: The incidence of peritonitis was 0,284 attack/patient/year. The most common organisms were coagulase negative staphylococci (18.3% followed by S. aureus (14.8% and gram-negative bacillus (13.1%. Peritonitis was more common in elderly, those with longer PD duration, low residual urine volume, patients with low PCR and hepatitis C. However, patients using erythropoietin and automated PD had low incidence of peritonitis compared to others. Mortality rate was higher in gram-negative and fungal peritonitis and prognosis was worse in gramnegative peritonitis CONCLUSION: Peritonitis incidence and aetiology were compatible with literature. One must be careful to protect residual renal function (RRF as peritonitis incidence was significantly reduced in patients with RRF. PCR values were significantly lower in peritonitis. Adequate protein intake and nutritional support may be important in this respect.

  13. Peritoneal mesothelioma

    International Nuclear Information System (INIS)

    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

  14. Peritoneal dialysis peritonitis: risk factors and effects

    2013-07-01

    Full Text Available Introduction: Peritonitis is the most frequent complication of peritoneal dialysis. It is the main cause of failure of the method and inclusion of patients in hemodialysis Purpose: The purpose of this study is to explore the risk factors of peritoneal dialysis peritonitis as well as the acute and long-term effects of peritonitis on peritoneal membrane function and success of the method. Methods: Literature review of relevant articles in the database Pubmed as well as the official website of the International Society of Peritoneal Dialysis (ISPD was carried out. The search included articles published during the period 1986 -2012.Results: Lack of patient compliance with the peritoneal changes protocol, lack of social support, systemic diseases and connection systems are risk factors of peritonitis. Peritonitis causes transient increase of peritoneum permeability, loss of the ability of the peritoneum for ultrafiltration and, consequently, overhydration. Long-term, recurrent episodes of peritonitis resulting in permanent loss of peritoneum capacity for ultrafiltration even fibrosis that leads to failure of the method. Finally, its effect on the reduction of the residual renal function seems to be remarkable. Conclusions: Peritonitis is the most common infectious complication of peritoneal dialysis and the main cause of morbidity associated with the method. Moreover, it is the major cause of failure of the method and patients accession in hemodialysis. Any attempt to prevent peritonitis passes through the careful patient selection and effective patient education on compliance with the rules of asepsis during peritoneal changes.

    Fluorescence in situ hybridization (FISH) technology provides a promising molecular imaging tool to detect cervical cancer. Since manual FISH analysis is difficult, time-consuming, and inconsistent, the automated FISH image scanning systems have been developed. Due to limited focal depth of scanned microscopic image, a FISH-probed specimen needs to be scanned in multiple layers that generate huge image data. To improve diagnostic efficiency of using automated FISH image analysis, we developed a computer-aided detection (CAD) scheme. In this experiment, four pap-smear specimen slides were scanned by a dual-detector fluorescence image scanning system that acquired two spectrum images simultaneously, which represent images of interphase cells and FISH-probed chromosome X. During image scanning, once detecting a cell signal, system captured nine image slides by automatically adjusting optical focus. Based on the sharpness index and maximum intensity measurement, cells and FISH signals distributed in 3-D space were projected into a 2-D con-focal image. CAD scheme was applied to each con-focal image to detect analyzable interphase cells using an adaptive multiple-threshold algorithm and detect FISH-probed signals using a top-hat transform. The ratio of abnormal cells was calculated to detect positive cases. In four scanned specimen slides, CAD generated 1676 con-focal images that depicted analyzable cells. FISH-probed signals were independently detected by our CAD algorithm and an observer. The Kappa coefficients for agreement between CAD and observer ranged from 0.69 to 1.0 in detecting/counting FISH signal spots. The study demonstrated the feasibility of applying automated FISH image and signal analysis to assist cyto-geneticists in detecting cervical cancers.

    This paper describes the principle of a new fully automated digitally assisted coaxial bridge having a large bandwidth ranging from 60 Hz to 50 kHz. The performance of the bridge is evaluated making 1:1 comparisons between calculable ac resistors. The agreement between the calculated and the measured frequency dependence of the resistors is better than 5\\cdot {{10}-8} at frequencies up to 5 kHz, better than 1\\cdot {{10}-7} up to 20 kHz and better than 0.8\\cdot {{10}-6} up to 50 kHz. This bridge is particularly well suited to investigate the ac transport properties of graphene in the quantum Hall regime.

    This paper presents a computerized scheme to assist MRI operators in accurate and rapid determination of sagittal sections for MRI exam of cervical spinal cord. The algorithm of the proposed scheme consisted of 6 steps: (1) extraction of a cervical vertebra containing spinal cord from an axial localizer image; (2) extraction of spinal cord with sagittal image from the extracted vertebra; (3) selection of a series of coronal localizer images corresponding to various, involved portions of the extracted spinal cord with sagittal image; (4) generation of a composite coronal-plane image from the obtained coronal images; (5) extraction of spinal cord from the obtained composite image; (6) determination of oblique sagittal sections from the detected location and gradient of the extracted spinal cord. Cervical spine images obtained from 25 healthy volunteers were used for the study. A perceptual evaluation was performed by five experienced MRI operators. Good agreement between the automated and manual determinations was achieved. By use of the proposed scheme, average execution time was reduced from 39 seconds/case to 1 second/case. The results demonstrate that the proposed scheme can assist MRI operators in performing cervical spinal cord MRI exam accurately and rapidly.

    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.

    Optimal fluid removal on peritoneal dialysis (PD) requires removal of water coupled with sodium, which is predominantly achieved via the small pores in the peritoneal membrane. On the other hand, free-water transport takes place through aquaporin-1 channels, but leads to sodium retention and over hydration. PD prescription can be adapted to promote small pore transport to achieve improved sodium and fluid management. Both adequate dwell volume and dwell time are required for small pore transport. The dwell volume determines the amount of "wetted" peritoneal membrane being increased in the supine position and optimized at dwell volumes of approximately 1400 ml/m(2). Diffusion across the recruited small pores is time-dependent, favored by a long dwell time, and driven by the transmembrane solute gradient. According to the 3-pore model of conventional PD, sodium removal primarily occurs via convection. The clinical application of these principles is essential for optimal performance of PD and has resulted in a new approach to the automated PD prescription: adapted automated PD. In adapted automated PD, sequential short- and longer-dwell exchanges, with small and large dwell volumes, respectively, are used. A crossover trial in adults and a pilot study in children suggests that sodium and fluid removal are increased by adapted automated PD, leading to improved blood pressure control when compared with conventional PD. These findings are not explained by the current 3-pore model of peritoneal permeability and require further prospective crossover studies in adults and children for validation. PMID:26924063

    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

    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

    Since 2009, the peritoneal dialysis (PD) registry survey has been carried out as part of the annual nationwide survey conducted by the Statistical Survey Committee of the Japanese Society for Dialysis Therapy with the cooperation of the Japanese Society for Peritoneal Dialysis. In this report, the current status of PD patients is presented on the basis of the results of the survey conducted at the end of 2012. The subjects were PD patients who lived in Japan and participated in the 2012 survey. Descriptive analysis of various items was performed, which included the current status of the combined use of PD and another dialysis method such as hemodialysis (HD) or hemodiafiltration (HDF), the method of exchanging dialysate, the use of an automated peritoneal dialysis (APD) machine, and the rates of peritonitis and catheter exit-site infection. From the results of the facility survey in 2012, the number of PD patients was 9514, a decrease of 128 from 2011. Among the entire dialysis patient population, 3.1% were PD patients, a decrease of 0.1%. Among the studied patients, 347 had a peritoneal catheter and underwent peritoneal lavage, 175 were started on PD in 2012 but introduced to other blood purification methods in the same year, and 1932 underwent both PD and another dialysis method such as HD or HDF. The percentage of patients who underwent PD and another dialysis method increased with PD vintage: vintage of ≥2 years. The mean rate of peritonitis was 0.22 per patient per year. The mean rate of catheter exit-site infections was 0.36 per patient per year.

  9. Pathophysiology of the Peritoneal Membrane during Peritoneal Dialysis: The Role of Hyaluronan

    Directory of Open Access Journals (Sweden)

    Susan Yung

    2011-01-01

    Full Text Available During peritoneal dialysis (PD, constant exposure of mesothelial cells to bioincompatible PD solutions results in the denudation of the mesothelial monolayer and impairment of mesothelial cell function. Hyaluronan, a major component of extracellular matrices, is synthesized by mesothelial cells and contributes to remesothelialization, maintenance of cell phenotype, and tissue remodeling and provides structural support to the peritoneal membrane. Chronic peritoneal inflammation is observed in long-term PD patients and is associated with increased hyaluronan synthesis. During inflammation, depolymerization of hyaluronan may occur with the generation of hyaluronan fragments. In contrast to native hyaluronan which offers a protective role to the peritoneum, hyaluronan fragments exacerbate inflammatory and fibrotic processes and therefore assist in the destruction of the tissue. This paper will discuss the contribution of mesothelial cells to peritoneal membrane alterations that are induced by PD and the putative role of hyaluronan in these processes.

    1980-01-01

    We initiated a therapeutic program of continuous ambulatory peritoneal dialysis for patients with chronic renal failure. Our program resulted in many episodes of peritonitis arising from contamination due to the technical aspects of the procedure. Microbiologic evaluation showed that 73% of 97 episodes were culture positive, with gram-positive organisms causing most of the cases, especially early in dialysis. Gram-negative rods tended to occur later. Gram stains of dialysate effluent resulted in a disappointingly low yield of only 9% positivity. Cell counts were a dependable indicator of the presence of peritoneal inflammation and also of therapeutic success. Most patients responded well to intraperitoneal cephalothin, 125 mg/L for 10 to 14 d. The occurrence of peritonitis resulted in 0.93 years of hospitalization during the total of 15.45 patient-years on dialysis, which essentially negated the financial advantages of this method of treatment of chronic renal failure. For this to be a successful mode of therapy, advances in the prevention of peritonitis must be made. PMID:6985785

  12. Peritoneal lymphomatosis: case report

    International Nuclear Information System (INIS)

    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

    Full Text Available Peritonitis is an important problem of peritoneal dialysis patients. Although Gram (+ bacteria are more frequent, Gram (- bacteria can rarely be the cause of peritonitis. Yersinia enterocolitica is a Gram (- enteric bacteria that especially causes gastrointestinal infections via contaminated food intake in immunosuppressive situations such as haemochromatosis, desferroxamine therapy or chronic hepatitis. We report a 51-year-old man who had been undergoing SAPD because of chronic renal failure for 2 years. We evaluated his peritoneal fl uid because of symptoms of peritonitis. His peritoneal cellular composition was consistent with peritonitis and after the microbiological culture of the fl uid we determined Yersinia enterocolitica as the pathogenic agent. The peritonitis persisted despite the administration of long term combined antibiotherapy and we removed the peritoneal catheter. In conclusion, Yersinia enterocolitica peritonitis is resistant to conventional antibiotic therapy and an indication for catheter removal.

    2010-05-01

    Full Text Available Faulty requirements specifications lead to developing a faulty software system. This may require repeating the whole software engineering cycle wasting time and money. This paper presents an interactive semi-automated system that is a compromise between two approaches. The first tries to avoid the introduction of imprecision while the software requirements are being written. The other attempts to detect and possibly correct many types of imprecision after the software requirements are written. This is achieved by imposing the use of a good writing style and by interactively emulating a conversation between the requirements engineer and the user. This helps free the requirements engineer from such a systematic task, helps in processing many ill-structured statements, and helps maintain consistency in the used terminology. Explanations produced by the system helps in detecting and correcting any missed imprecision. The proposed techniques are easy enough to be used by non-technical stakeholders in different domains

    Pleural thickenings are caused by asbestos exposure and may evolve into malignant pleural mesothelioma. An early diagnosis plays a key role towards an early treatment and an increased survival rate. Today, pleural thickenings are detected by visual inspection of CT data, which is time-consuming and underlies the physician's subjective judgment. A computer-assisted diagnosis system to automatically assess pleural thickenings has been developed, which includes not only a quantitative assessment with respect to size and location, but also enhances this information with an anatomical description, i.e. lung side (left, right), part of pleura (pars costalis, mediastinalis, diaphragmatica, spinalis), as well as vertical (upper, middle, lower) and horizontal (ventral, dorsal) position. For this purpose, a 3D anatomical model of the lung surface has been manually constructed as a 3D atlas. Three registration sub-steps including rigid, affine, and nonrigid registration align the input patient lung to the 3D anatomical atlas model of the lung surface. Finally, each detected pleural thickening is assigned a set of labels describing its anatomical properties. Through this added information, an enhancement to the existing computer-assisted diagnosis system is presented in order to assure a higher precision and reproducible assessment of pleural thickenings, aiming at the diagnosis of the pleural mesothelioma in its early stage.

    Full Text Available Giant peritoneal loose bodies are rare lesions, originating from auto-amputated appendices epiploicae. They may cause urinary or gastrointestinal obstruction and, should the radiologist not be familiar with the entity, can potentially be confused with malignant or parasitic lesions.Familiarity with their characteristic computed tomographic features is essential to prevent unnecessary surgery in the asymptomatic patient. We present a case of a 70-year-old man diagnosed with two giant peritoneal loose bodies.

    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 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

    Full Text Available Introduction: Peritonitis is the most important and frequent infectious complication of peritoneal dialysis. It is the most common cause of failure of the method and inclusion of patients in hemodialysis. Purpose: Τhe purpose of this study is to explore the diagnostic approaches of peritoneal dialysis peritonitis. Methods: Literature review of relevant articles in the database Pubmed as well as the official website of the International Society of Peritoneal Dialysis (ISPD was carried out. The search included articles published during 1996-2013. Results: According to the International Society of Peritoneal Dialysis, peritonitis requires the presence of two of the following criteria: (a cloudy peritoneal fluid, (b symptoms of inflammation of the peritoneum and (c the presence of microorganisms in the peritoneal fluid (> 100 leukocytes / μL of the solution of which most (> 50 % are polymorphnuclear. Some rules of sampling peritoneal fluid for culture and Gram staining are important for the right and immediate treatment of peritonitis: a the first cloudy peritoneal bag is the best sample b sending of the first bag for cultures should be done as early as possible in order to begin the appropriate antibiotic therapy. Gram stain, although in most cases is negative, it is particularly useful for the diagnosis of fungal peritonitis. Conclusions: Patient education, mainly of new Peritoneal Dialysis patients, about the early recognizing of cloudy fluids and exit-site infection, must be the primary concern of a Peritoneal Dialysis Unit. Careful use of antibiotics will reduce the frequency of negative cultures in order not to exceed the limit of 20% of the tests, as recommended by the International Society of Peritoneal Dialysis.

    Peritoneal encapsulation(PE) is a rare congenital malformation, characterized by a thin accessory peritoneal membrane which covers all or part of the small bowel, forming an accessory peritoneal sac. Most cases areasymptomatic and diagnosed incidentally during surgery and/or autopsy. Clinical presentation with intestinal obstruction is extremely rare and we report a case. A 25-year-old male, referred to emergency department with diffuse abdominal pain, crampy, with 8 h evolution, associated with nausea, vomiting and constipation in the last 48 h. The abdominal examination revealed an asymmetric and fixed distension, with hard consistency on palpation of lower abdominal quadrants. The abdominal radiography reveals a small bowel distension and fluid levels. Submitted to laparoscopic surgery that recourse to conversion because there is a total peritoneal encapsulation of the small bowel. After opening the peritoneal sac, we find a rotation of mesentery, at its root, conditioning twisting of small bowel and consequently occlusion. Uneventful postoperative with discharged at the 6th day. The PE is a very rare congenital anomaly characterized by abnormal bowel back into the abdominal cavity in the early stages of development. Your knowledge becomes important because, although rare, it might be diagnosis in patients with intestinal obstruction, in the absence of other etiologic factors.

    An automated fluidic instrument is described that rapidly determines the total (99)Tc content of aged nuclear waste samples, where the matrix is chemically and radiologically complex and the existing speciation of the (99)Tc is variable. The monitor links microwave-assisted sample preparation with an automated anion exchange column separation and detection using a flow-through solid scintillator detector. The sample preparation steps acidify the sample, decompose organics, and convert all Tc species to the pertechnetate anion. The column-based anion exchange procedure separates the pertechnetate from the complex sample matrix, so that radiometric detection can provide accurate measurement of (99)Tc. We developed a preprogrammed spike addition procedure to automatically determine matrix-matched calibration. The overall measurement efficiency that is determined simultaneously provides a self-diagnostic parameter for the radiochemical separation and overall instrument function. Continuous, automated operation was demonstrated over the course of 54 h, which resulted in the analysis of 215 samples plus 54 hly spike-addition samples, with consistent overall measurement efficiency for the operation of the monitor. A sample can be processed and measured automatically in just 12.5 min with a detection limit of 23.5 Bq/mL of (99)Tc in low activity waste (0.495 mL sample volume), with better than 10% RSD precision at concentrations above the quantification limit. This rapid automated analysis method was developed to support nuclear waste processing operations planned for the Hanford nuclear site.

    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.

    The vasoactive hormone angiotensin II initiates its major hemodynamic effects through interaction with AT1 receptors, a member of the class of G protein-coupled receptors. Acting through its AT1R, angiotensin II regulates blood pressure and renal salt and water balance. Recent evidence points to additional pathological influences of activation of AT1R, in particular inflammation, fibrosis and atherosclerosis. The transcription factor nuclear factor κB, a key mediator in inflammation and atherosclerosis, can be activated by angiotensin II through a mechanism that may involve arrestin-dependent AT1 receptor internalization. Peritoneal dialysis is a therapeutic modality for treating patients with end-stage kidney disease. The effectiveness of peritoneal dialysis at removing waste from the circulation is compromised over time as a consequence of peritoneal dialysis-induced peritoneal fibrosis. The non-physiological dialysis solution used in peritoneal dialysis, i.e. highly concentrated, hyperosmotic glucose, acidic pH as well as large volumes infused into the peritoneal cavity, contributes to the development of fibrosis. Numerous trials have been conducted altering certain components of the peritoneal dialysis fluid in hopes of preventing or delaying the fibrotic response with limited success. We hypothesize that structural activation of AT1R by hyperosmotic peritoneal dialysis fluid activates the internalization process and subsequent signaling through the transcription factor nuclear factor κB, resulting in the generation of pro-fibrotic/pro-inflammatory mediators producing peritoneal fibrosis.

    2016-05-01

    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%.

    A carefully planned, structured, and supervised physiotherapy program, following a surgery, is crucial for the successful diagnosis of physical injuries. Nearly 50 % of the surgeries fail due to unsupervised, and erroneous physiotherapy. The demand for a physiotherapist for an extended period is expensive to afford, and sometimes inaccessible. Researchers have tried to leverage the advancements in wearable sensors and motion tracking by building affordable, automated, physio-therapeutic systems that direct a physiotherapy session by providing audio-visual feedback on patient's performance. There are many aspects of automated physiotherapy program which are yet to be addressed by the existing systems: a wide classification of patients' physiological conditions to be diagnosed, multiple demographics of the patients (blind, deaf, etc.), and the need to pursue patients to adopt the system for an extended period for self-care. In our research, we have tried to address these aspects by building a health behavior change support system called KinoHaptics, for post-surgery rehabilitation. KinoHaptics is an automated, wearable, haptic assisted, physio-therapeutic system that can be used by a wide variety of demographics and for various physiological conditions of the patients. The system provides rich and accurate vibro-haptic feedback that can be felt by the user, irrespective of the physiological limitations. KinoHaptics is built to ensure that no injuries are induced during the rehabilitation period. The persuasive nature of the system allows for personal goal-setting, progress tracking, and most importantly life-style compatibility. The system was evaluated under laboratory conditions, involving 14 users. Results show that KinoHaptics is highly convenient to use, and the vibro-haptic feedback is intuitive, accurate, and has shown to prevent accidental injuries. Also, results show that KinoHaptics is persuasive in nature as it supports behavior change and habit building

    Feline infectious peritonitis (FIP) frequently results in death in cats. It is caused by a mutated, highly contagious coronavirus, and it is more common in indoor cats in multicat households. A complex interaction between the coronavirus and the feline immune system causes disseminated vasculitis, which is the hallmark of FIP. New tests are being developed, but the antemortem diagnosis of FIP continues to be difficult and frustrating. Current treatments are crude and involve supportive care and immunosuppression. Minimizing exposure is the best method of preventing infection.

  5. CT findings of peritoneal carcinomatosis

    International Nuclear Information System (INIS)

    CT findings in 137 patients with peritoneal cacinomatosis were reviewed to determine the CT signs of peritoneal malignancy. CT of the 20 liver cirrhosis and 17 tuberculous peritonitis were also reviewed to define the differential point between benign and malignant peritoneal change. The results were as follows. 1. The most common primary malignancy encountered in peritoneal carcinomatosis was stomach Ca.(50.4%), followed by pancreas Ca, hepatoma, colon Ca. and ovarian Ca. 2. Ascites was the most common CT feature of peritoneal malignancy, present in 99 cases (72.3%). The amount of ascites was voluminous, grade III in 70% of cases and showed high density ascites with average 23 Hounsfield units. 3. Greater omentum involvement was noted in 88 patients, peritoneum in 71 patients and mesentery in 65% patients. There was no correlation of the primary malignancy type with the incidence or pattern of the above mentioned site. 4. Bowel wall thickenings were observed in 51 patients, among which transverse colon was most frequently involved. 5. Mean attenuation value of ascites in liver cirrhosis was 10.7 HU, which was much lower than that of peritoneal carcinomatosis. 6. Even though intraperitoneal findings in Tbc. Peritonitis showed tendency of relatively small amount of ascites with more predominant mesenteric change, but, the findings of high density ascites, change of peritoneum and omentum etc. were very similar to those of peritoneal carcinomatosis. Therefore, based on only intraperitoneal change, differential diagnosis between them was difficult. 7. False negatives in CT diagnosis of peritoneal carcinomatosis occurred in 7 cases. There were tiny nodular changes in intraperitoneal cavity without ascites on operative findings

She had been treated with continuous ambulatory peritoneal dialysis (CAPD) for 13 months prior to the development of peritonitis. The patient demonstrated no improvement with a 3-day therapy of intraperitoneal vancomycin and netilmicin. Meanwhile, smear of centrifuged dialysate revealed acid fast bacilli on two occasions. We, then, started anti-TB therapy with oral isoniazid (INAH), rifampin and ethambutal. The symptoms subsided within three days. In the first week, the patient lost her peritoneal ultrafiltration and needed daytime automatic peritoneal dialysis. At the last follow-up examination, 12 months after treatment, she remained well on standard CAPD.

    Full Text Available A lumbar peritoneal (LP shunt is a technique of cerebrospinal fluid (CSF diversion from the lumbar thecal sac to the peritoneal cavity. It is indicated under a large number of conditions such as communicating hydrocephalus, idiopathic intracranial hypertension, normal pressure hydrocephalus, spinal and cranial CSF leaks, pseudomeningoceles, slit ventricle syndrome, growing skull fractures which are difficult to treat by conventional methods (when dural defect extends deep in the cranial base or across venous sinuses and in recurrent cases after conventional surgery, raised intracranial pressure following chronic meningitis, persistent bulging of craniotomy site after operations for intracranial tumors or head trauma, syringomyelia and failed endoscopic third ventriculostomy with a patent stoma. In spite of the large number of indications of this shunt and being reasonably good, safe, and effective, very few reports about the LP shunt exist in the literature. This procedure did not get its due importance due to some initial negative reports. This review article is based on search on Google and PubMed. This article is aimed to review indications, complications, results, and comparison of the LP shunt with the commonly practiced ventriculoperitoneal (VP shunt. Shunt blocks, infections, CSF leaks, overdrainage and acquired Chiari malformation (ACM are some of the complications of the LP shunt. Early diagnosis of overdrainage complications and ACM as well as timely appropriate treatment especially by programmable shunts could decrease morbidity. Majority of recent reports suggest that a LP shunt is a better alternative to the VP shunt in communicating hydrocephalus. It has an advantage over the VP shunt of being completely extracranial and can be used under conditions other than hydrocephalus when the ventricles are normal sized or chinked. More publications are required to establish its usefulness in the treatment of wide variety of indications.

    The swan neck presternal catheter is composed of 2 flexible (silicon rubber) tubes joined by a titanium connector at the time of implantation. The exit site is located in the parasternal area. The catheter located on the chest was designed to reduce the incidence of exit site infections compared to peritoneal dialysis catheters with abdominal exits. From August 1991 to September 30, 2001, 974 swan neck presternal catheters were implanted worldwide. At the university of Missouri, 150 of these catheters were implanted and followed for over 130 patient years. Presternal catheters tended to perform better than swan neck abdominal catheters regarding exit and tunnel infections, even though they were implanted in several patients in whom regular catheters with the exit on the abdomen would be difficult or impossible to implant. Two-year survival probability of presternal catheters was 0.95. Recurrent/refractory peritonitis was the only reason for catheter failure. The catheter is particularly useful in obese patients (body mass index >35), patients with ostomies, children with diapers and fecal incontinence, and patients who want to take baths without the risk of exit contamination. Many patients prefer presternal catheter because of better body image. Disadvantages of the presternal catheter are minimal. Compared with abdominal catheters, dialysis-solution flow is slightly slower because of the increased catheter length; however, slower flow is insignificant clinically. There is a possibility of catheter disconnection in the tunnel, but this complication is extremely rare in adults and easily corrected. Finally, the implantation technique is more challenging compared with that of single-piece, abdominal catheters. PMID:12085389

    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 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.

    Since its initial description in 1964, research has transformed spontaneous bacterial peritonitis (SBP) from a feared disease (with reported mortality of 90%) to a treatable complication of decompensated cirrhosis,albeit with steady prevalence and a high recurrence rate. Bacterial translocation, the key mechanism in the pathogenesis of SBP, is only possible because of the concurrent failure of defensive mechanisms in cirrhosis.Variants of SBP should be treated. Leucocyte esterase reagent strips have managed to shorten the 'tap-toshot' time, while future studies should look into their combined use with ascitic fluid pH. Third generation cephalosporins are the antibiotic of choice because they have a number of advantages. Renal dysfunction has been shown to be an independent predictor of mortality in patients with SBP. Albumin is felt to reduce the risk of renal impairment by improving effective intravascular volume, and by helping to bind proinflammatory molecules. Following a single episode of SBP, patients should have long-term antibiotic prophylaxis and be considered for liver transplantation.

    We investigated the feasibility and effectiveness of a telemedicine system for monitoring pediatric patients undergoing automated peritoneal dialysis (APD) at home. The system uses modem-based communication between the patient's cycler and a computer in the dialysis unit, which allows data transmission and storage, and live patient-physician interaction by ISDN lines, modem, microphone with stereo speakers, and digital cameras for private video-conferencing and image capture. Two children aged 10 and 12 years, who live 1500 and 40 km from the dialysis unit, respectively, have been using the system for 7 months. All of the APD treatment data were stored and examined; 122 televisits were performed. The APD data show that both patients have complied with their dialysis prescription. The telemedicine system broadens patient/physician interchange and increases the quality of care and the life of children on peritoneal dialysis. PMID:12626104

    A simple and rapid method for the determination of the methylene blue active substances assay based on in-syringe automation of magnetic stirring-assisted dispersive liquid-liquid microextraction was developed. The proposed method proved to be valid for the determination of anionic surfactant in waste, pond, well, tap, and drinking water samples. Sample mixing with reagents, extraction and phase separation were performed within the syringe of an automated syringe pump containing a magnetic stirring bar for homogenization and solvent dispersion. The syringe module was used upside-down to enable the use of chloroform as an extraction solvent of higher density than water. The calibration was found to be linear up to 0.3mg/L using only 200 µL of solvent and 4 mL of sample. The limits of detection (3σ) and quantification (10σ) were 7.0 µg/L and 22 µg/L, respectively. The relative standard deviation for 10 replicate determinations of 0.1mg/L SBDS was below 3%. Concentrations of anionic surfactants in natural water samples were in the range of 0.032-0.213 mg/L and no significant differences towards the standard method were found. Standard additions gave analyte recoveries between 95% and 106% proving the general applicability and adequateness of the system to MBSA index determination. Compared to the tedious standard method requiring up to 50 mL of chloroform, the entire procedure took only 345 s using 250-times less solvent.

  5. Water channels in peritoneal dialysis.

    Science.gov (United States)

    Devuyst, Olivier

    2010-01-01

    Peritoneal dialysis involves diffusive and convective transports and osmosis through the highly vascularized peritoneal membrane. Several lines of evidence have demonstrated that the water channel aquaporin-1 (AQP1) corresponds to the ultrasmall pore predicted by the modelization of peritoneal transport. Proof-of-principle studies have shown that up-regulation of the expression of AQP1 in peritoneal capillaries is reflected by increased water permeability and ultrafiltration, without affecting the osmotic gradient and the permeability for small solutes. Inversely, studies in Aqp1 mice have shown that haploinsufficiency in AQP1 is reflected by significant attenuation of water transport. Recent studies have identified lead compounds that could act as agonists of aquaporins, as well as putative binding sites and potential mechanisms of gating the water channel. By modulating water transport, these pharmacological agents could have clinically relevant effects in targeting specific tissues or disease states. These studies on the peritoneal membrane also provide an experimental framework to investigate the role of water channels in the endothelium and various cell types.

    We present the first application of submicrometric magnetic nanoporous carbons (μMNPCs) as sorbents for automated solid-phase extraction (SPE). Small zeolitic imidazolate framework-67 crystals are obtained at room temperature and directly carbonized under an inert atmosphere to obtain submicrometric nanoporous carbons containing magnetic cobalt nanoparticles. The μMNPCs have a high contact area, high stability, and their preparation is simple and cost-effective. The prepared μMNPCs are exploited as sorbents in a microcolumn format in a sequential injection analysis (SIA) system with online spectrophotometric detection, which includes a specially designed three-dimensional (3D)-printed holder containing an automatically actuated electromagnet. The combined action of permanent magnets and an automatically actuated electromagnet enabled the movement of the solid bed of particles inside the microcolumn, preventing their aggregation, increasing the versatility of the system, and increasing the preconcentration efficiency. The method was optimized using a full factorial design and Doehlert Matrix. The developed system was applied to the determination of anionic surfactants, exploiting the retention of the ion-pairs formed with Methylene Blue on the μMNPC. Using sodium dodecyl sulfate as a model analyte, quantification was linear from 50 to 1000 μg L(-1), and the detection limit was equal to 17.5 μg L(-1), the coefficient of variation (n = 8; 100 μg L(-1)) was 2.7%, and the analysis throughput was 13 h(-1). The developed approach was applied to the determination of anionic surfactants in water samples (natural water, groundwater, and wastewater), yielding recoveries of 93% to 110% (95% confidence level).

    International Nuclear Information System (INIS)

    To compare the CT findings of peritoneal tuberculosis (PT) and peritoneal carcinomatosis (PC) based on the morphologic features of the peritoneum and assess the relationship between the degree of peritoneal thickness and the severity of omental infiltration in PT and PC. We retrospectively reviewed the CT findings of 15 patients with PT and 14 with PC. We checked morphologic changes of the peritoneum as seen on CT, for the following points: 1) the presence of peritoneal change: 2) the pattern of any change-diffuse thickening, plaque or nodularity, combined thickening (diffuse and plaque, or nodularity) 3) the degree of thickness on the whole peritoneum - mild (grossly definite, but not more than 3mm), moderate (more than 3mm); 4) the presence of irregularity on the peritoneal surface. We also evaluated the significance of the relationship between peritoneal thickness and omental infiltration in both disease entities. The degree of omental infiltration was described as follows : grade 1 (no change or focal smudge pattern); grade 2 (diffuse smudge), grade 3 (omental cake regardless extent). Peritoneal change was seen in 12 of 15 PT patients and in 7 of 14 PC patients. In all 12 PT patients, the pattern of change was diffuse thickening, and among the seven PC patients, there was diffuse thickening in one, plaque or nodular thickening in four, and combined thickening in two. In PT patients, the degree of thickness on the whole peritoneum was mild in six and moderate in six, and in PC patients it was mild in two and moderate in one. An irregular peritoneum surface was seen in one patient with PT and in two with PC. The degree of omental infiltration in PT was grade 1 in four patients, grade 2 in six and grade 3 in five. In PC, it was grade 1 in six patients, grade 2 in two and grade 3 in six. Smooth diffuse thickening of the peritoneum was seen in 11 of 15 PT cases and in one of 14 PC (P 0.5).

    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.

We tested a technique to provide rapid automated total spine MRI screening with improved tissue contrast through optimized fat-water separation.Methods: The entire spine was auto-imaged in two contiguous 35 cm field of view (FOV sagittal stations, utilizing out-of-phase fast gradient echo (FGRE and T1 and/or T2 weighted fast spin echo (FSE IDEAL (Iterative Decomposition of Water and Fat with Echo Asymmetric and Least-squares Estimation sequences. 18 subjects were studied, one twice at 3.0T (pre and post contrast and one at both 1.5 T and 3.0T for a total of 20 spine examinations (8 at 1.5 T and 12 at 3.0T. Images were independently evaluated by two neuroradiologists and run through Automated Spine Survey Iterative Scan Technique (ASSIST analysis software for automated vertebral numbering.Results: In all 20 total spine studies, neuroradiologist and computer ASSIST labeling were concordant. In all cases, IDEAL provided uniform fat and water separation throughout the entire 70 cm FOV imaged. Two subjects demonstrated breast metastases and one had a large presumptive schwannoma. 14 subjects demonstrated degenerative disc disease with associated Modic Type I or II changes at one or more levels. FGRE ASSIST afforded subminute submillimeter in-plane resolution of the entire spine with high contrast between discs and vertebrae at both 1.5 and 3.0T. Marrow signal abnormalities could be particularly well characterized with IDEAL derived images and parametric maps.Conclusion: IDEAL ASSIST is a promising MRI technique affording a rapid automated high resolution, high contrast survey of the entire spine with optimized tissue characterization.

    Sclerosing peritonitis is a dramatic complication of continuous ambulatory peritoneal dialysis and chronic peritoneal inflammation. Both visceral and parietal surfaces of the peritoneal cavity are involved. A thickened peritoneum encloses the small intestine in a "cocoon" formation which often leads to intestinal occlusion. CT scan may help obtaining an early diagnosis but diagnosis is often established with some delay or even at the time of laparotomy. Our report describes three cases of this uncommon peritoneal fibrosis syndrome which caused intestinal obstruction requiring surgical intervention. PMID:14524162

    Aim: To compare the histological upgrade rate of ultrasound (US)-guided vacuum-assisted removal (VAR) and US-14 G-automated core needle biopsy (ACNB) in the diagnosis of papillary breast lesions. Materials and methods: Two hundred and seventy-one biopsies of 230 papillary lesions were examined, which underwent subsequent surgical excision or long-term follow-up after US-ACNB (n = 206) or US-VAR (n = 65). The false-negative and atypical papilloma underestimation rate were compared between the ACNB and VAR groups. Patient and lesion characteristics were collected. The histological upgrade rates of the diagnosis were estimated and compared. Results: Out of 271 papillary lesions, 195 (80.0%) were benign, 21 (7.7%) were atypical, and 55 (20.3%) were malignant. There were no false negatives or underestimated atypical papillomas in the VAR group. However, in the ACNB group, the false-negative rate was 7.6% (12 of 157 benign papillomas, 95% CI; 4.4-12.9%, p = 0.039) and the atypical papilloma underestimation rate was 33% (five of 15 atypical papillomas, 95% CI; 15.2-58.3%, p = 0.135). The histological upgrade rates of the diagnosis for papillary breast lesions were 0% for the VAR (0 of 66) group and 10.2% for the ACNB (21 of 206) group before adjusting for the population (p = 0.003). Conclusions: ACNB was associated with significantly higher false-negative and histological upgrade rates of diagnosis for papillary breast lesions than VAR.

    Summary: In order to investigate the effect of ligustrazine (Lig) i.p. on peritoneal permeability inperitoneal dialysis and its side effects, creatinine was given intravenously and continuously tomaintain the high plasma creatinine level. All the rabbits were divided into three groups: normalcontrol group (group A), group B treated with 0. 12 % Lig and group C treated with 0. 24 % Lig.The peritoneal dialysis of all rabbits lasted 2 h. The plasma and dialysate levels of glucose, proteinand creatinine were observed immediate, 30 min, 60 min, 90 min,120 min after dialysis. Creasti-nine dialysate/plasma ratio (D/P), protein D/P ratio, glucose D/Do at different time points afterdialysis and creatinine mass transfer area coefficient (MTAC) at 120 min were calculated. Thestructures of peritoneum were observed under optical microscope and electron microscope aftercontinuously intraperitoneal injection of Lig for 14 days. The results showed that the 90-min and120-min creatinine D/P ratios in the group C were higher than in the group A. The 120-min creatinine MATC in the group C was higher than in the group A. The rabbits treated with Lig did notshow significant structure changes of peritoneum and signs of peritoneal irritation. It was suggest-ed that Lig could increase mass transfer ability of peritoneum without significant side effects.

  2. Peritoneal dialysis solution and nutrition.

    2012-01-01

    20-70% of peritoneal dialysis patients have some signs of malnutrition. Anorexia, protein and amino acid losses in dialysate, advanced age of elderly patients, inflammation and cardiac failure are among the main causes. Modern dialysis solutions aim to reduce these causes, but none of them is without side effects: glucose is relatively safe and brings additional energy but induces anorexia and lipid abnormalities, amino acids compensate dialysate losses but may increase uremia and acidosis, icodextrin helps control hyperhydration and chronic heart failure and minimizes glucose side effects, but may sometimes cause inflammation, and poly chamber bags allow the replacement of lactate by bicarbonate and are more biocompatible, decrease GDP, induce less inflammation and have a better effect on nutritional status. However, it appears that the management of nutrition with the different solutions available nowadays necessitates various combinations of solutions adapted to different patient profiles and there is not actually a single universal solution to minimize malnutrition in peritoneal dialysis patients.

    Objective: to analyze the complications related to peritonitis and catheter exit-site infections, in patients on peritoneal dialysis at home. Method: quantitative and cross-sectional study, carried out with 90 patients on peritoneal dialysis at home, in a municipality in the Northeast region of Brazil. For data collection, it was used two structured scripts and consultation on medical records. Descriptive analysis and comparison tests among independent groups were used, considering p<0.05 as level of statistical significance. Results: by comparing the frequency of peritonitis and the length of treatment, it was found that patients over two years of peritoneal dialysis were more likely to develop peritonitis (X²=6.39; p=0.01). The number of episodes of peritoneal catheter exit-site infection showed association with the length of treatment (U=224,000; p=0.015). Conclusion: peritonitis and catheter exit-site infection are associated with the length of treatment. PMID:26487141

    Full Text Available Pediatric Spontaneous Bile duct perforation is a rare clinical condition with only around 150 cases reported worldwide. Early management gives excellent prognosis but the condition often presents a diagnostic dilemma. Hepato-biliary Technetium-99m-iminodiacetic acid scintiscan is the diagnostic investigation of choice but its availability in third world countries is limited. We present two cases of spontaneous biliary peritonitis in children, which were diagnosed without scintiscanning. The first case was a one-and -a half-year-old child, who was diagnosed with biliary peritonitis without pneumoperitoneum by a combination of Ultrasound (USG, Contrast enhanced computed tomography (CECT, and Magnetic Resonance Imaging (MRI. The child underwent USG-guided drainage and subsequent cholecystectomy with hepatico-jejunostomy. The second child also had biliary peritonitis without pneumoperitoneum, which was initially suspected on USG. CECT revealed dilated gall bladder and fluid collection in sub-hepatic space and pelvis. Abdominal paracentesis revealed presence of bile. The child responded to conservative therapy. Both are doing well on two-year follow-up. In a patient with jaundice, biliary tract abnormalities and/or free fluid, either generalized or localized to peri-cholecystic/sub-hepatic space on USG/CT/MRI, in the absence of pneumoperitoneum, suggest a diagnosis of biliary perforation even in the absence of scintiscanning.

    During peritoneal dialysis (PD), constant exposure of mesothelial cells to bioincompatible PD solutions results in the denudation of the mesothelial monolayer and impairment of mesothelial cell function. Hyaluronan, a major component of extracellular matrices, is synthesized by mesothelial cells and contributes to remesothelialization, maintenance of cell phenotype, and tissue remodeling and provides structural support to the peritoneal membrane. Chronic peritoneal inflammation is observed in...

    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.

  16. Pathophysiology and prevention of postoperative peritoneal adhesions

    Institute of Scientific and Technical Information of China (English)

    Willy Arung1; Michel Meurisse; Olivier Detry

    2011-01-01

    Peritoneal adhesions represent an important clinical challenge in gastrointestinal surgery. Peritoneal adhesions are a consequence of peritoneal irritation by infection or surgical trauma, and may be considered as the pathological part of healing following any peritoneal injury, particularly due to abdominal surgery. The balance between fibrin deposition and degradation is critical in determining normal peritoneal healing or adhesion formation. Postoperative peritoneal adhesions are a major cause of morbidity resulting in multiple complications, many of which may manifest several years after the initial surgical procedure. In addition to acute small bowel obstruction, peritoneal adhesions may cause pelvic or abdominal pain, and infertility. In this paper, the authors reviewed the epidemiology, pathogenesis and various prevention strategies of adhesion formation, using Medline and PubMed search. Several preventive agents against postoperative peritoneal adhesions have been investigated. Their role aims in activating fibrinolysis, hampering coagulation, diminishing the inflammatory response, inhibiting collagen synthesis or creating a barrier between adjacent wound surfaces. Their results are encouraging but most of them are contradictory and achieved mostly in animal model. Until additional findings from future clinical researches, only a meticulous surgery can be recommended to reduce unnecessary morbidity and mortality rates from these untoward effects of surgery. In the current state of knowledge, pre-clinical or clinical studies are still necessary to evaluate the effectiveness of the several proposed prevention strategies of postoperative peritoneal adhesions.

  17. A Comparison of Fully Automated Methods of Data Analysis and Computer Assisted Heuristic Methods in an Electrode Kinetic Study of the Pathologically Variable [Fe(CN) 6 ] 3–/4– Process by AC Voltammetry

    KAUST Repository

    Morris, Graham P.

    2013-12-17

    Fully automated and computer assisted heuristic data analysis approaches have been applied to a series of AC voltammetric experiments undertaken on the [Fe(CN)6]3-/4- process at a glassy carbon electrode in 3 M KCl aqueous electrolyte. The recovered parameters in all forms of data analysis encompass E0 (reversible potential), k0 (heterogeneous charge transfer rate constant at E0), α (charge transfer coefficient), Ru (uncompensated resistance), and Cdl (double layer capacitance). The automated method of analysis employed time domain optimization and Bayesian statistics. This and all other methods assumed the Butler-Volmer model applies for electron transfer kinetics, planar diffusion for mass transport, Ohm\\'s Law for Ru, and a potential-independent Cdl model. Heuristic approaches utilize combinations of Fourier Transform filtering, sensitivity analysis, and simplex-based forms of optimization applied to resolved AC harmonics and rely on experimenter experience to assist in experiment-theory comparisons. Remarkable consistency of parameter evaluation was achieved, although the fully automated time domain method provided consistently higher α values than those based on frequency domain data analysis. The origin of this difference is that the implemented fully automated method requires a perfect model for the double layer capacitance. In contrast, the importance of imperfections in the double layer model is minimized when analysis is performed in the frequency domain. Substantial variation in k0 values was found by analysis of the 10 data sets for this highly surface-sensitive pathologically variable [Fe(CN) 6]3-/4- process, but remarkably, all fit the quasi-reversible model satisfactorily. © 2013 American Chemical Society.

    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)

    Severe peritonitis causing death is one of the most devastating complications of peritoneal dialysis (PD). Since the predictive value of C-reactive protein (CRP) in PD fluid has not been assessed, the objective of the present study is to evaluate its predictive value and clinical correlation in patients on PD with peritonitis. One hundred and twenty patients on continuous ambulatory PD (CAPD) were enrolled and their serum and fluid CRP (Fl. CRP) were evaluated at the start of CAPD. All patients who developed peritonitis were further evaluated for serum and fluid CRP. The patients were categorized into four groups, namely: normal patients (control group), patients with peritonitis, patients with peritonitis leading to catheter removal, and death due to peritonitis. Sixty-five patients developed peritonitis of whom, catheter removal was performed in eight patients. Five patients died due to peritonitis-related complications. Fl. CRP showed a significant difference among the three groups, unlike S. CRP. Estimation of CRP in the peritoneal fluid may be a useful marker to monitor the onset of peritonitis.

    A 70-years of age, male patient with underlying type 2 diabetes mellitus, hypertension, dyslipidemia and ischemic heart disease had undergone continuous ambulatory peritoneal dialysis (CAPD)for 3 years without any episodes of peritonitis. He was diagnosed with necrotizing fasciitis and later developed peritonitis after receiving a laceration from an aquatic injury suffered during the flood disaster of 2011. The blood culture, necrotic tissue and the clear dialysate collected upon admission had shown Aeromonas sobria. The route of peritonitis may be from the hematogenous spread of A. sobria resulting in necrotizing fasciitis. A. sobria should be considered as the pathogen of peritonitis in PD patients who have history of wounds from contaminated water. We suggest that the PD patients who present with septicemia and did not meet the criteria for peritonitis, the initial dialysate effluent should be sent for culture. The benefit of this is to allow early recognition and treatment of peritonitis.

    International Nuclear Information System (INIS)

    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.

    Meconium peritonitis is a rare prenatal disease with an increased rate of morbidity and mortality in the neonatal period. Distinctive features revealed by prenatal and postnatal ultrasoundmay be present: abdominal calcifications, ascites, polyhydramnios, meconium pseudocyst, echogenic mass and dilated bowel or intestinal obstruction. Establishing clear postnatal treatment and prognosis is difficult because of the heterogeneity of the results obtained by ultrasound. The aim of the study is to determine how prenatal diagnosis of meconium peritonitis is associated with perinatal management and further evolution. Clinical results are different depending on the presence of antenatal diagnosis of meconium peritonitis and its form, which can be mild or severe. Surgical treatment and management of meconium peritonitis depend on the clinical presentation of the newborn. Meconium peritonitis diagnosed prenatally differs from that of the newborn, not only concerning the mortality rates but also through reduced morbidity and overall better prognosis.

    During peritoneal dialysis (PD), the peritoneal membrane undergoes ageing processes that affect its function. Here we analyzed associations of patient age and dialysis vintage with parameters of peritoneal transport of fluid and solutes, directly measured and estimated based on the pore model, for individual patients. Thirty-three patients (15 females; age 60 (21-87) years; median time on PD 19 (3-100) months) underwent sequential peritoneal equilibration test. Dialysis vintage and patient age did not correlate. Estimation of parameters of the two-pore model of peritoneal transport was performed. The estimated fluid transport parameters, including hydraulic permeability (LpS), fraction of ultrasmall pores (α u), osmotic conductance for glucose (OCG), and peritoneal absorption, were generally independent of solute transport parameters (diffusive mass transport parameters). Fluid transport parameters correlated whereas transport parameters for small solutes and proteins did not correlate with dialysis vintage and patient age. Although LpS and OCG were lower for older patients and those with long dialysis vintage, αu was higher. Thus, fluid transport parameters--rather than solute transport parameters--are linked to dialysis vintage and patient age and should therefore be included when monitoring processes linked to ageing of the peritoneal membrane.

    Full Text Available Peritoneal dialysis therapy has increased in popularity since the end of the 1970s. This method provides a patient survival rate equivalent to hemodialysis and better preservation of residual renal function. However, technique failure by peritonitis, and ultrafiltration failure, which is a multifactorial complication that can affect up to 40% of patients after 3 years of therapy. Encapsulant peritoneal sclerosis is an extreme and potentially fatal manifestation. Causes of inflammation in peritoneal dialysis range from traditional factors to those related to chronic kidney disease per se, as well as from the peritoneal dialysis treatment, including the peritoneal dialysis catheter, dialysis solution, and infectious peritonitis. Peritoneal inflammation generated causes significant structural alterations including: thickening and cubic transformation of mesothelial cells, fibrin deposition, fibrous capsule formation, perivascular bleeding, and interstitial fibrosis. Structural alterations of the peritoneal membrane described above result in clinical and functional changes. One of these clinical manifestations is ultrafiltration failure and can occur in up to 30% of patients on PD after five years of treatment. An understanding of the mechanisms involved in peritoneal inflammation is fundamental to improve patient survival and provide a better quality of life.

    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 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.

    2016-01-01

    A 56-year-old man who was a Jehovah's Witness with an advanced directive against autologous procedures developed acute kidney injury needing renal replacement therapy while he was intubated and ventilated on the intensive care unit. He was being treated for hyperosmolar hyperglycaemic state. He also had a healing laparotomy wound, having undergone a splenectomy less than a month ago following a road traffic accident. His hyperkalaemia and metabolic acidosis were refractory to medical treatment. As he became oligoanuric, decision was taken to carry out acute peritoneal dialysis (PD) by inserting a Tenckhoff catheter in his abdomen using peritoneoscopic technique. The patient was started on automated PD without any complications. His urine output gradually improved, and his renal function eventually recovered. On discharge from hospital, his renal function was within normal range, and he had no abdominal complications from the acute PD. PMID:27581233

    A 79-year-old man on continuous ambulatory peritoneal dialysis (CAPD) developed abdominal pain and cloudy peritoneal fluid two days after colonoscopy that revealed multiple diverticula. The white blood cell count was 9,000 cells/μL, C-reactive protein level was 6.86 mg/dL, and the white blood cell count of the peritoneal fluid was 7,800 cells/μL, suggesting acute peritonitis. Empiric therapy consisting of cefazolin and ceftazidime slowly improved the patient's symptoms. The initial microbiological examination of the peritoneal fluid demonstrated Morganella morganii. He was changed from CAPD to hemodialysis. It is important to consider M. morganii peritonitis in patients with colonic diverticula.

    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.

    Despite technological improvements in dialysis connectology and dialysis technique, peritonitis remains the most common and most significant complication of peritoneal dialysis (PD) in children. Most children undergoing chronic PD experience none or only one peritonitis episode, while others have multiple episodes or episodes secondary to unusual organisms. Knowledge of potential risk factors and likely patient outcome is imperative if treatment is to be optimized. In this review we will, in turn, describe episodes of peritonitis that are characterized as either relapsing, recurrent, repeat or zoonosis-related to highlight the clinical issues that are commonly encountered by clinicians treating these infections.

    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

    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. PMID:20117860

    In patients on continuous ambulant peritoneal dialysis (CAPD) treatment, the peritoneal membrane is continuously exposed to the high glucose concentration contained in the dialysate. This may lead to the local generation of advanced glycation end-products (AGEs). To test this hypothesis we evaluated the plasma and dialysate AGE concentrations in five CAPD patients. The dialysate was measured after a 1 h and after a 12 h dwell time. Additionally, in two patients an immunohistochemical investigation of the peritoneal membrane for AGE was performed. For the determination of AGE an ELISA using a polyclonal antibody against AGE bovine serum albumin was used; the immunohistochemical staining was performed using the streptavidin-biotin complex method. We found only low concentrations of AGE in the dialysate after a 1 h dwell time; after 12 h, however, the dialysate AGE was even greater than the plasma concentration. In both peritoneal specimens we found positive staining for AGE in the interstitium of the mesothelial layer. The dialysate AGE contained a high proportion of high-molecular-weight AGE proteins and low-molecular-weight AGE was found to be in the same concentration range as the total serum AGE. We conclude that there is local generation of AGE in the peritoneal membrane and a 'washing out' of AGE from the peritoneal membrane during longer dwell times. We speculate that the accumulation of AGE might lead to some of the functional and morphological alterations observed after long-term CAPD.

    Fuzzy inference systems (FIS) enable automated assessment and reasoning in a logically consistent manner akin to the way in which humans reason. However, since no conventional fuzzy set theory is in the Boolean frame, it is proposed that Boolean consistent fuzzy logic should be used in the evaluation of rules. The main distinction of this approach is that it requires the execution of a set of structural transformations before the actual values can be introduced, which can, in certain cases, lead to different results. While a Boolean consistent FIS could be used for establishing the diagnostic criteria for any given disease, in this paper it is applied for determining the likelihood of peritonitis, as the leading complication of peritoneal dialysis (PD). Given that patients could be located far away from healthcare institutions (as peritoneal dialysis is a form of home dialysis) the proposed Boolean consistent FIS would enable patients to easily estimate the likelihood of them having peritonitis (where a high likelihood would suggest that prompt treatment is indicated), when medical experts are not close at hand.

    Despite medical advancements, the inflammatory cascade and oxidative stress worsen the prognosis in most cases of peritonitis. Curcumin has emerged as a potential antioxidant and anti-inflammatory agent in few of the acute inflammatory and infective conditions. We examined the effect of intraperitoneal injection of curcumin in endotoxin-induced peritonitis in rats. The blood and peritoneal fluid samples were collected at 3 and 24 h following the induction of peritonitis. Animals were sacrificed at 24 h and the organs preserved. The histopathological report of lung, liver, and intestines in the curcumin-treated rats showed maintenance of tissue architecture to a large extent compared to the control group which showed massive congestion, hemorrhage, and necrosis. The blood and peritoneal fluid total count and differential neutrophil counts were significantly higher at 24 h of induction of peritonitis. Serum amyloid assay and lipid peroxidation were significantly lower, and myeloperoxidase assay was higher in the curcumin-treated group at the end of 24 h; thus, curcumin probably demonstrated a neutrophil-mediated immunopotentiation and anti-inflammatory action thereby protecting the animal from endotoxemia-induced multi-organ damage.

    Full Text Available Peritoneal deterioration causing structural changes and functional decline is a major complication of peritoneal dialysis (PD. The aim of this study was to explore effluent biomarkers reflecting peritoneal deterioration. In an animal study, rats were intraperitoneally administered with PD fluids adding 20 mM methylglyoxal (MGO or 20 mM formaldehyde (FA every day for 21 days. In the MGO-treated rats, tenascin-C (TN-C levels in the peritoneal effluents were remarkably high and a cluster of TN-C-positive mesothelial cells with epithelial-to-mesenchymal transition- (EMT- like change excessively proliferated at the peritoneal surface, but not in the FA-treated rats. Effluent matrix metalloproteinase-2 (MMP-2 levels increased in both the MGO- and FA-treated rats. In a clinical study at 18 centers between 2006 and 2013, effluent TN-C and MMP-2 levels were quantified in 182 PD patients with end-stage renal disease. Peritoneal function was estimated using the peritoneal equilibration test (PET. From the PET results, the D/P Cr ratio was correlated with effluent levels of TN-C (ρ = 0.57, p<0.001 and MMP-2 (ρ = 0.73, p<0.001. We suggest that TN-C in the effluents may be a diagnostic marker for peritoneal deterioration with EMT-like change in mesothelial cells in PD.

    Full Text Available Background/Aims: The main purpose of the present study was to determine the effect of peritoneal charge barrier dysfunction on hypoalbuminemia during CAPD. Methods: We measured the association of dialysis dose, peritoneal equilibration test (PET results (ratio of dialysate and plasma creatinine, and peritoneal charge barrier index (ratio of pancreatic and salivary α-amylase clearance on protein loss in 33 patients on maintenance CAPD. All patients were from a single institution and were diagnosed with chronic nephritis (n = 18 cases, diabetic nephropathy (n = 8, hypertension (n = 5, and hepatitis B virus-associated glomerulonephritis (n = 2. Results: The mean (± SD dialysate protein loss was 4.04 g (± 1.97 per day. Protein loss was positively correlated with dialysis dose (r = 0.438, p = 0.01 but was not significantly correlated with PET results. The mean (± SD peritoneal charge barrier index was 6.12 (± 21.20 and was inversely correlated with protein loss into the peritoneal dialysate (r = -0.532, p Conclusions: Taken together, our study of CAPD patients indicates that protein loss into the peritoneal dialysate increases with peritoneal dialysis dose and with disruption of the peritoneal charge barrier.

    O157, O26, and O111 are the most important O serogroups of enterohemorrhagic Escherichia coli worldwide. Recently we reported a strategy for discriminating these serotypes from the others using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) based on the S10-spc-alpha operon gene-encoded ribosomal protein mass spectrum (S10-GERMS) method. To realize the fully automated identification of microorganisms at species- or serotype-level with the concept of S10-GERMS method, novel software named Strain Solution for MALDI-TOF MS was developed. In this study, the Strain Solution was evaluated with a total of 45 E. coli isolates including O26, O91, O103, O111, O115, O121, O128, O145, O157, O159, and untyped serotypes. The Strain Solution could accurately discriminate 92% (11/12) of O157 strains, 100% (13/13) of O26 and O111 strains from the others with three biomarkers in an automated manner. In addition, this software could identify 2 different E. coli strains (K-12 as a non-O157 representative and O157) in mixed samples. The results suggest that Strain Solution will be useful for species- or serotype-level classification of microorganisms in the fields of food safety and diagnostics.

  5. 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.

    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.

    Full Text Available The first episode of peritonitis affects survival of the peritoneal membrane as a medium for dialysis as well as survival of patients. The aim of this study is to investigate risk factors associated with the first episode of peritonitis in Southern Chinese continuous ambulatory peritoneal dialysis (CAPD patients.This is a single-center, retrospective, cohort study. All incident CAPD patients from 1 January 2006 to 31 December 2010 were recruited, and followed up until their first episode of peritonitis or 31 December, 2012. Baseline demographic, socioeconomic, clinical and laboratory data were collected. Cox proportional model was used to determine the factors associated with the first episode of peritonitis.In a cumulative 30756.5 patient-months follow-up (the median vintage 26.1 months of 1117 CAPD patients, 309(27.7% patients presented the first episodes of peritonitis. The cumulative peritonitis-free survival was 86.2%, 78.1%, 71.4% and 57.8% at 1, 2, 3 and 5 year, respectively. The multivariate analysis showed that factors associated with risk for the first episode of peritonitis were elderly patients (>65 years [hazard ratio (HR = 1.427, 95% confidence interval (CI = 1.051 to 1.938, P = 0.023], male(HR = 1.315, 95% CI = 1.028 to 1.684, P = 0.030, lower education level (HR = 1.446, 95% CI: 1.127 to 1.855, P = 0.004 and albumin <38g/L (HR = 1.425, 95% CI: 1.112 to 1.825, P = 0.005.Older age, male, lower educational level and hypoalbuminemia at the commencement of PD were the risk factors associated with the first episode of peritonitis in Southern Chinese CAPD patients.

  9. Process automation

    International Nuclear Information System (INIS)

    Process automation technology has been pursued in the chemical processing industries and to a very limited extent in nuclear fuel reprocessing. Its effective use has been restricted in the past by the lack of diverse and reliable process instrumentation and the unavailability of sophisticated software designed for process control. The Integrated Equipment Test (IET) facility was developed by the Consolidated Fuel Reprocessing Program (CFRP) in part to demonstrate new concepts for control of advanced nuclear fuel reprocessing plants. A demonstration of fuel reprocessing equipment automation using advanced instrumentation and a modern, microprocessor-based control system is nearing completion in the facility. This facility provides for the synergistic testing of all chemical process features of a prototypical fuel reprocessing plant that can be attained with unirradiated uranium-bearing feed materials. The unique equipment and mission of the IET facility make it an ideal test bed for automation studies. This effort will provide for the demonstration of the plant automation concept and for the development of techniques for similar applications in a full-scale plant. A set of preliminary recommendations for implementing process automation has been compiled. Some of these concepts are not generally recognized or accepted. The automation work now under way in the IET facility should be useful to others in helping avoid costly mistakes because of the underutilization or misapplication of process automation. 6 figs

    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

    1995-01-01

    A new peritoneal dialysate containing pyruvate anions was developed in order to avoid cytotoxic effect of conventional lactate-based dialysate. The dialysate has a final pH of 5.4 to 5.6 and is composed of 1.36-3.86% glucose-monohydrate; 132 mmol/l sodium; 1.75 mmol/l calcium; 0.75 mmol/l magnesium; 102 mmol/l chloride and 35 mmol/l pyruvate. For cytotoxicity testing peritoneal macrophages, and mesothelial cells (MC) were exposed to conventional lactate dialysate, and pyruvate dialysate. We investigated the O2- generation and cytokine synthesis after endotoxin stimulation in peritoneal macrophages and the proliferation of mesothelial cells of cultured human MC. After exposure to lactate dialysate O2- generation and cytokine synthesis in peritoneal macrophages and proliferation of mesothelial cells were inhibited when compared to solution containing pyruvate and the control solution. After preincubation with 3.86% glucose containing solutions, all negative effects became even more pronounced in the lactate group whereas after pre-exposure to pyruvate containing solution the toxic effects were absent. These results suggest that the acute toxic effects of commercially available peritoneal dialysates can be avoided by the use of sodium pyruvate instead of sodium lactate.

    Peritoneal dialysis (PD) is acknowledged worldwide as a well-accepted form of renal replacement therapy (RRT) for end-stage renal disease (ESRD). Ideally, PD should be the preferred modality of RRT for ESRD in developing countries due to its many inherent advantages. Some of these are cost savings (especially if PD fluids are manufactured locally or in a neighboring country), superior rehabilitation and quality of life (QOL), home-based therapy even in rural settings, avoidance of hospital based treatment and the need for expensive machinery, and freedom from serious infections (hepatitis B and C). However, this is not the ground reality, due to certain preconceived notions of the health care givers and governmental agencies in these countries. With an inexplicable stagnation or decline of PD numbers in the developed world, the future of PD will depend on its popularization in Latin America and in Asia especially countries such as China and India, with a combined population of 2.5 billion and the two fastest growing economies worldwide. A holistic approach to tackle the issues in the developing countries, which may vary from region to region, is critical in popularizing PD and establishing PD as the first-choice RRT for ESRD. At our center, we have been pursuing a 'PD first' policy and promoting PD as the therapy of choice for various situations in the management of renal failure. We use certain novel strategies, which we hope can help PD centers in other developing countries working under similar constraints. The success of a PD program depends on a multitude of factors that are interlinked and inseparable. Each program needs to identify its strengths, special circumstances, and deficiencies, and then to strategize accordingly. Ultimately, teamwork is the 'mantra' for a successful outcome, the patient being central to all endeavors. A belief and a passion for PD are the fountainhead and cornerstone on which to build a quality PD program. PMID:19494625

    Peritonitis is a debilitating infectious complication of peritoneal dialysis (PD). Drug-resistant bacterial peritonitis typically has a lower response rate to antibiotics. In the past 15 years, newer antibiotics with activities against drug-resistant Gram-positive bacteria have been developed. In most circumstances, peritonitis due to methicillin-resistant staphylococci responds to vancomycin. If vancomycin cannot be used due to allergy and/or non-susceptibility, there is increasing evidence that linezolid and daptomycin are the drugs of choice. It is reasonable to start linezolid orally or intravenously, but subsequent dose reduction may be necessary in case of myelosuppression. Daptomycin can be given intravenously or intraperitoneally and has excellent anti-biofilm activity. Other treatment options for drug-resistant Gram-positive bacterial peritonitis include teicoplanin, tigecycline and quinupristin/dalfopristin. Teicoplanin is not available in some countries (e.g. the USA). Tigecycline can only be given intravenously. Quinupristin/dalfopristin is ineffective against Enterococcus faecalis and there is only low-quality evidence to support its efficacy in the treatment of peritonitis. Effective newer antibiotics against drug-resistant Gram-negative bacteria are lacking. Polymyxins can be considered, but evidence on its efficacy is limited. In this review, we will discuss the potential use of newer antibiotics in the treatment of drug-resistant bacterial peritonitis in PD patients. PMID:27478608

    2009-08-15

    Purpose: We aimed to describe computed tomography (CT) findings in patients with peritoneal, omental and mesenteric lymphoma involvement. Materials and methods: We searched our archive retrospectively to find out patients with peritoneal, omental and mesenteric lymphoma involvement. We found 16 patients with non-hodgkin lymphoma meeting these criteria. CT studies of these patients were reevaluated for the presence of peritoneal involvement, ascites, omental mass, organomegaly, retroperitoneal lymphadenopathy, bowel wall thickening and other associated findings. Results: There were 14 males and 2 females with peritoneal and/or mesenteric and omental lymphoma involvement. Mean age was 39 (range 4-76). Subgroups of non-hodgkin lymphoma were diffuse large B-cell lymphoma (n = 11), small cell lymphocytic lymphoma (n = 2), small cleaved cell lymphoma (n = 1), T-cell lymphoma (n = 1) and Burkitt's lymphoma (n = 1). Peritoneal involvement was seen in 15 patients (93.8%) in the form of linear (n = 12) and nodular (n = 3) thickening. Ascites was seen in 12 (75%) patients. Omental and mesenteric masses were present in 10 (66.6%) and 10 (66.6%) patients, respectively. Bowel wall thickening, retroperitoneal lymphadenopathy and hepatosplenomegaly were also common and observed in 10, 10 and 11 patients, respectively. Solid organ involvement in the form of liver and splenic lesions was seen in 9 (56%) patients. Conclusion: Peritoneal involvement can be seen in many subtypes of lymphoma and most frequently in diffuse large B-cell lymphoma. Peritoneal lymphomatosis can mimic peritoneal carcinomatosis and should be included in the differential diagnosis list in patients with ascites, hepatosplenic lesions and unidentified cause of peritoneal thickening on CT in a male patient.

    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.

    Objective. This study reviews the relevant publications on the clinical effects of icodextrin in peritoneal dialysis (PD). Design. The study provides a systematic review of the literature (MEDLINE search with icodextrin as the keyword). Results. Icodextrin induces sustained transcapillary ultrafiltration during long dwell periods. It also stimulates increased removal of sodium by the peritoneal membrane, reduction of extracellular water (ECW) and total body water (TBW). Effects of icodextrin on blood pressure control and residual renal function are discrepant. Icodextrin induces a reduction in the formation of advanced glycation end-products, while the longitudinal changes in the peritoneal membrane transport are less prominent. Conclusions. Use of icodextrin in PD improves the sodium and fluid balance. Icodextrin is potentially more biocompatible, when compared with the conventional glucose solutions. The side effects are rare.

  6. Computerized tomography study in peritoneal tuberculosis

    International Nuclear Information System (INIS)

    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

    2009-01-01

    Full Text Available A patient with alcoholic cirrhosis of the liver, portal hypertension with hepatic encephalopathy and spontaneous bacterial peritonitis (SBP was admitted in an obtunded condition. Attempts at delineating the aetiology of the SBP using conventional cultures as well as automated systems were not successful. The use of non-anionic surfactant agents such as Tween 80-incorporated blood agar and Triton X treatment of the specimens facilitated the growth of Klebsiella pneumoniae from the ascitic fluid, which otherwise would have been concluded to represent culture-negative neutrocytic ascites. Thus, the use of the aforementioned agents could be explored in elucidating the aetiology of body cavity infections when conventional methods fail.

    Case-report of protozoal infection (Blastocystis bominis) during Pseudomonas peritonitis in male patient with intestinal diverticulosis on continuous ambulatory peritoneal dialysis (CAPD) treatment for chronic renal failure (CRF). Microscopic morphology and cultural characteristics are summarized from current literature. Photographic images in phase contrast from fresh-observation of faeces and peritoneal fluid are reported. Although other Protozoa (e.g. Acanthamoeba free-living) have already been found in dialysis fluid, this is the first case, referred in literature, of Blastocystis bominis infection in CAPD patients. Some pathogenetic hypothesis are done involving Blastocystis bominis in peritoneal infection, especially in immunodepressed patients like dialysed ones. Although many chemotherapeutics are provided for this protozoiasis during enteritis, in our case no supplement was required except specific antibiotic therapy for Pseudomonas infection. Symbion or pathogen? Is now-a-day the question which troubles parasitologists. Systemic research of Protozoa in dialysed patients is anyhow advisable. PMID:8848771

    A 33-year-old Caucasian man with end-stage renal disease secondary to biopsy-proven IgA nephropathy, managed with continuous ambulatory peritoneal dialysis (PD), presented with PD-related peritonitis, the causal organism being a non-branching Gram-positive bacillus, Rhodococcus equi. Initial empirical Gram positive and negative coverage with cefazolin and ceftazidime was unsuccessful, but following isolation of the organism, and conversion to intraperitoneal vancomycin and oral ciprofloxacin, the peritonitis episode resolved. At day 10, vancomycin was switched to azithromycin for a total of 6 weeks of antimicrobial therapy. The PD catheter was preserved, and the patient remained peritonitis-free at 6 months of follow-up.

    Rothia muciliaginosa (R. mucilaginosa) is a facultative, Gram-positive coccus that is considered to be part of the normal flora of the mouth and respiratory tract. There are sporadic reports of the organism causing endocarditis in patients with heart valve abnormalities, as well as meningitis, septicemia, and pneumonia associated with intravenous drug abuse. However, it is an unusual pathogen in cases of peritoneal dialysis (PD)-associated peritonitis. Although R. mucilaginosa is generally susceptible to penicillin, ampicillin, cefotaxime, imipenem, rifampicin, and glycopeptides, there are no guidelines for the treatment of PD-associated peritonitis. Herein, we report a case of PD-associated peritonitis due to R. mucilaginosa that was resolved with intraperitoneal antibiotic treatment. PMID:26484045

    Full Text Available We report a case of synchronous primary colonic adenocarcinoma and malignant mesothelioma. A 61-year-old male presented with a six-month history of fatigue and weight loss. An abdominal computed tomography (CT scan showed a 5.8 cm partially obstructing mass in the cecum with ascites and peritoneal thickening. A biopsy of the large mass showed an adenocarcinoma. Because the patient was clinically thought to be a T4 colon carcinoma with peritoneal metastatic lesions (M1, prior to initiating chemotherapy, a debulking right hemicolectomy was performed. Resection of the colon and ileum revealed a T3N0 colonic mucinous adenocarcinoma and concurrent diffuse malignant peritoneal mesothelioma. Presenting synchronous colonic and peritoneal mesothelial primary malignancies are exceedingly rare but must be considered to prevent incorrect clinical staging.

  15. Peritoneal tuberculosis: how to obtain a confident diagnosis?

    International Nuclear Information System (INIS)

    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)

    During continuous ambulatory peritoneal dialysis (CAPD), peritoneal host defence mechanisms are repeatedly exposed to dialysis solutions (with unphysiological composition) which may compromise peritoneal immune cell functions. In this context, the current study focused on the capacity of peripheral and peritoneal PMN to release leukotrienes following exposure to conventional CAPD dialysates. PMN were obtained from peripheral blood of healthy volunteers and from the peritoneal effluent of CAPD patients with acute peritonitis. Following isolation, cells were incubated in fresh CAPD dialysates or control buffer, and calcium ionophore A23187-stimulated leukotriene synthesis was measured. Additional experiments included RP-HPLC analysis and radioactivity monitoring of lipoxygenase products in PMN labelled with 14C-arachidonic acid. Leukotriene B4 and leukotrienes C4/D4/E4 were determined by radioimmunoassay. Ionophore-triggered leukotriene release from cells exposed to control buffer was pronounced in inflammatory peritoneal PMN (70.4 +/- 31.3 ng/5 x 10(6) cells LTB4 and 13.4 +/- 19.8 ng/5 x 10(6) cells LTC4/D4/E4, mean +/- SD, n = 14) when compared to healthy peripheral PMN (26.6 +/- 16.9 ng/ml LTB4 and 6.3 +/- 6.6 ng/ml LTC4/D4/E4, n = 12). Incubation in fresh solutions for peritoneal dialysis severely depressed leukotriene release from both cell populations. These results indicate a severe inhibition of cellular responsiveness as a consequence of dialysate exposure which could contribute to the impairment of host defence early in the CAPD cycle.

  19. Biocompatible Peritoneal Dialysis Fluids: Clinical Outcomes

    Yeoungjee Cho

    2012-01-01

    Full Text Available Peritoneal dialysis (PD is a preferred home dialysis modality and has a number of added advantages including improved initial patient survival and cost effectiveness over haemodialysis. Despite these benefits, uptake of PD remains relatively low, especially in developed countries. Wider implementation of PD is compromised by higher technique failure from infections (e.g., PD peritonitis and ultrafiltration failure. These are inevitable consequences of peritoneal injury, which is thought to result primarily from continuous exposure to PD fluids that are characterised by their “unphysiologic” composition. In order to overcome these barriers, a number of more biocompatible PD fluids, with neutral pH, low glucose degradation product content, and bicarbonate buffer have been manufactured over the past two decades. Several preclinical studies have demonstrated their benefit in terms of improvement in host cell defence, peritoneal membrane integrity, and cytokine profile. This paper aims to review randomised controlled trials assessing the use of biocompatible PD fluids and their effect on clinical outcomes.

    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.

  3. Complications after placement of peritoneal catheter

    2011-01-01

    Full Text Available Introduction. Peritoneal dialysis is one of the modalities used for treatment of end-stage chronic kidney failure. Nowadays, this method is complementary to haemodialysis and renal transplantation. Owing to the rich vascularization of the peritoneum, it is used in the processes of osmosis and diffusion, enabling the removal of uremic material from the body. The procedure includes introduction of peritoneal fluid via the peritoneal catheter. Complications. The catheter is placed through the anterior abdominal wall with its tip positioned in the small pelvis. There are several techniques for catheter placement considered minimally invasive, which, however, may be associated with various complications. These complications can be divided into mechanical (catheter dysfunction, cuff protrusion, hernia, dialysate leaks, visceral perforation and infectious (early peritonitis, exit site or tunnel infection, surgical wounds. In most cases, such complications are rare and can be successfully managed using conservative therapy; however, in some situations severe complications can endanger the life of the patient. On-time recognition of complications, particularly in patients at risk, is of paramount importance for an effective treatment. The development of complications can increase the morbidity and the chance of treatment failure, and therefore transfer to haemodialysis. Conclusion. The preoperative evaluation and determination of the risk factors as well as the early recognition and adequate management of complications are essential in their prevention.

    The aim of our study was the use of the optimal imaging of the peritoneal cavity (PC) for continuous ambulatory peritoneal dialysis (CAPD)-related problems. Ultrasonography (USG), direct abdominal radiography (DAR), peritoneoscintigraphy (PSG), and standard peritoneo-computed tomography (PCT) with reconstruction (R-PCT) were performed in 25 patients on CAPD from three to 44 months. Studies were done at the beginning of CAPD (1-3 months) as well as in the noncomplicated and complicated course of CAPD. Group 1 comprised 17 patients in whom 77 PC images were taken in the non-complicated course of CAPD. Group II comprised 15 patients in whom 65 images were taken during or after complications. For USG and DAR we used standard equipment, PSG was done with sulfur colloid labeled with technetium 99m (Tc 99m), PCT, and R-PCT were done with Omnipaque and Somatom HiQ Siemens unit. In PCT, two- and three dimensional reconstruction were done by our own computer program. USG was recommended for imaging of tunnel infections, exit-site infection (ESI), and adhesion. PSG was useful in almost all observed complications of CAPD except thickening of the peritoneal membrane (PM). Standard PCT with R-PCT was more useful than PCT because of a more legible image of the peritoneal cavity, which gives the possibility of monitoring fluid distribution and measuring of intraperitoneal fluid volume.

    AIM: To evaluate the role of peritoneal lavage cytology (PLC) and carcinoembryonic antigen (CEA) determination of peritoneal washes (pCEA) in predicting the peritoneal metastasis and prognosis after curative resection of gastric cancer.METHODS: PLC and radioimmunoassay of CEA were performed in peritoneal washes from 64 patients with gastric cancer and 8 patients with benign diseases.RESULTS: The positive rate of pCEA (40.6%) was significantly higher than that of PLC (23.4%) (P<0.05).The positive rates of PLC and pCEA correlated with the depth of tumor invasion and lymph node metastasis (P<0.05). pCEA was found to have a higher sensitivity and a lower false-positive rate in predicting peritoneal metastasis after curative resection of gastric cancer as compared to PLC. The 1-, 3-, and 5-year survival rates of patients with positive cytologic findings or positive pCEA results were significantly lower than those of patients with negative cytologic findings or negative pCEA results (P<0.05). Multivariate analysis indicated that pCEA was an independent prognostic factor for the survival of patients with gastric cancer.CONCLUSION: Intraoperative pCEA is a more sensitive and reliable predictor of peritoneal metastasis as well as prognosis in patients with gastric cancer as compared to PLC method.

    Background Long-term peritoneal dialysis (PD) requires that the peritoneal membrane remain effective for dialysis. Research directed toward human peritoneal morphology and structure is limited. The present study was performed to investigate morphological changes of the human peritoneal membrane during PD and to elucidate the possible mechanisms of its functional deterioration. Methods A total of 32 peritoneal biopsies were performed in normal subjects (n=10), uremic nondialysis patients (n=12) at the time of catheter insertion, and PD patients (n=10) at the time of catheter removal or reinsertion or at the time of renal transplantation. Peritoneal morphology was examined by light microscopy, scanning electron microscopy, and transmission electron microscopy. Results The peritoneal membrane in normal subjects consisted of a monolayer of mesothelial cells on a basement membrane and a layer of connective tissue containing cells, blood vessels, and lymphatic vessels. Mesothelial cells were polygonal, often elongated, and had numerous microvilli on their luminal surface. There were lots of oval or roundish pinocytotic vesicles in the cytoplasm of the mesothelial cells. The peritoneal morphology of uremic nondialysis patients was similar to that of normal subjects. However, significant abnormalities of the peritoneal membrane were observed in PD patients, and the changes were found to be progressive. Microvilli were the first site of damage which involved microvilli shortening, a gradual reduction in their number, and, eventually, the total disappearance of microvilli. Mesothelial cells then detached from the basement membrane, disappearing completely in some cases. In the end, the peritoneal membrane consisted only of submesothelial connective tissue without any cells.Conclusions PD can modify peritoneal morphology and structure. The morphological change is progressive and may be one of the important causes of peritoneal failure. Peritoneal biopsies can provide lots of

    2014-04-01

    Full Text Available Multiple shunt failure is a challenge in pediatric neurosurgery practice and one of the most feared complications of hydrocephalus. Objective: To demonstrate that laparoscopic procedures for distal ventriculoperitoneal shunt failure may be an effective option for patients who underwent multiple revisions due to repetitive manipulation of the peritoneal cavity, abdominal pseudocyst, peritonitis or other situations leading to a “non reliable” peritoneum. Method: From March 2012 to February 2013, the authors reviewed retrospectively the charts of six patients born and followed up at our institution, which presented with previous intra-peritoneal complications and underwent ventriculoperitoneal shunt revision assisted by video laparoscopy. Results: After a mean follow-up period of nine months, all patients are well and no further shunt failure was identified so far. Conclusion: Laparoscopy assisted shunt revision in children may be, in selected cases, an effective option for patients with multiple peritoneal complications due to ventriculo-peritoneal shunting.

    Full Text Available Background. Peritoneal Carcinomatosis Index (PCI is a widely established scoring system that describes disease burden in isolated colorectal peritoneal carcinomatosis (CPC. Its significance may be diminished with complete cytoreduction. We explore the utility of the recently described Peritoneal Surface Disease Severity Score (PSDSS and compare its prognostic value against PCI. Methods. The endpoints were overall survival (OS, progression-free survival (PFS, and survival less than 18 months (18 MS. Results. Fifty patients underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC for CPC from 2003 to 2014, with 98% achieving complete cytoreduction. Median OS was 28.8 months (95% CI, 18.0–39.1; median PFS was 9.4 months (95% CI, 7.7–13.9. Univariate analysis showed that higher PCI was significantly associated with poorer OS (HR 1.11; 95% CI, 1.03–1.20 and PFS (HR 1.09; 95% CI, 1.03–1.14. Conversely, PSDSS was not associated with either endpoint. Multivariate analysis showed that PCI, but not PSDSS, was predictive of OS and PFS. PCI was also able to discriminate survival outcomes better than PSDSS for both OS and PFS. There was no association between 18 MS and either score. Conclusion. PCI is superior to PSDSS in predicting OS and PFS and remains the prognostic score of choice in CPC patients undergoing CRS/HIPEC.

    Virtually all mutations causing Hunter syndrome (mucopolysaccharidosis type II) are expected to be new mutations. Therefore, as a means of molecular diagnosis, we developed a rapid method to sequence the entire iduronate-2-sulfatase (IDS) coding region. PCR amplicons representing the IDS cDNA were sequenced with an automatic instrument, and output was analyzed by computer-assisted interpretation of tracings, using Staden programs on a Sun computer. Mutations were found in 10 of 11 patients studied. Unique missense mutations were identified in five patients: H229Y (685{r_arrow}T, severe phenotype); P358R (1073C{r_arrow}G, severe); R468W (1402C{r_arrow}T, mild); P469H (1406C{r_arrow}A, mild); and Y523C (1568A{r_arrow}G, mild). Nonsense mutations were identified in two patients: R172X (514C{r_arrow}T, severe) and Q389X (1165C{r_arrow}T, severe). Two other patients with severe disease had insertions of 1 and 14 bp, in exons 3 and 6, respectively. In another patient with severe disease, the predominant (<95%) IDS message resulted from aberrant splicing, which skipped exon 3. In this last case, consensus sequences for splice sites in exon 3 were intact, but a 395C{r_arrow}G mutation was identified 24 bp upstream from the 3` splice of exon 3. This mutation created a cryptic 5` splice site with a better consensus sequence for 5` splice sites than the natural 5` splice site of intron 3. A minor population of the IDS message was processed by using this cryptic splice site; however, no correctly spliced message was detected in leukocytes from this patient. The mutational topology of the IDS gene is presented. 46 refs., 6 figs., 2 tabs.

  14. The peritoneal mesothelioma: 4 cases reports

    International Nuclear Information System (INIS)

    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

    Spontaneous bacterial peritonitis (SBP) is a treatable complication of decompensated cirrhosis. Coagulopathy with evidence of hyperfibrinolysis or clinically evident disseminated intravascular coagulation precludes paracentesis. Alcoholic hepatitis with fever, leucocytosis and abdominal pain should be evaluated for SBP. Oral ofloxacin is as effective as parenteral cefotaxime in treatment of SBP except for inpatients with vomiting,encephalopathy, or renal failure. Albumin is superior to hydroxyethyl starch in treatment of SBP.

  17. Peritoneal tuberculosis. Also important in Germany

    International Nuclear Information System (INIS)

    As a result of the increase in the number of foreigners living in Germany and in the number of patients with AIDS, there will also be an increase in the incidence of abdominal tuberculosis in Germany. The following report describes the case of a 24-year-old female patient with peritoneal tuberculosis, the most common manifestation of abdominal tuberculosis. Computed tomography showed typical pathological alterations; the diagnosis was confirmed by intralaparascopic biopsy. (orig.)

    A 65-year-old female was admitted to our hospital with abdominal distension. Abdominal CT and MRI revealed massive ascites and an omental cake, but the ovaries were of normal size. After an omentum biopsy was performed during open abdominal surgery, she was diagnosed as peritoneal serous papillary adenocarcinoma. After 6 courses of chemotherapy with paclitaxel and carboplatin, the massive ascites totally disappeared, and a second look operation could be performed. She is still alive with no sign of recurrence. PMID:21829076

    Full Text Available OBJECTIVE: central neurocytoma is a low grade tumor of neuroglial origin and a relatively new histological entity. Only a few cases have been reported and its biological behavior is still uncertain. Some cases have shown an aggressive behavior (local recurrence, malignant dedifferentiation or CSF dissemination and challenged the initial view of its relative benignity. A case of central neurocytoma with peritoneal dissemination is presented. CASE: a six years-old boy with recurrent neurocytoma of III ventricle and left thalamus showed fast growth of tumor rest and ascites three and a half years after subtotal removal of the lesion. Tumor cells were identified in the ascitic fluid and implanted in the peritoneum. Chemotherapy was initiated immediately after diagnosis of peritoneal dissemination (etoposide, carboplatin, doxorubicin and cyclophosphamide. The patient developed metabolic imbalance and respiratory failure due to rapid formation of ascitic fluid and died 3 days after the diagnosis of peritoneal dissemination was established. CONCLUSION: central neurocytoma is a low grade tumor with low values of the proliferative index in the majority of cases. In spite of that, some tumors may present a very aggressive behavior and extraneural dissemination. Evaluation of proliferative index may be a guideline parameter for planning adjuvant therapies after surgical treatment in selected cases. Extraneural dissemination may occur in some cases specially in patients with ventriculoperitoneal shunt.

    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.).

    2005-01-01

    Generalized biliary peritonitis is a serious intra-abdominal emergency. Most of them occur due to duodenal ulcer perforation and rapidly evolve into bacterial peritonitis due to contamination by gut organisms and food. In this situation, recognition of the pathology and its treatment is straightforward and is usually associated with a good outcome. There are a few unusual causes of biliary peritonitis, of which rupture of the biliary tree is one.We describe a rare case of biliary peritonitis due to rupture of an intra-hepatic biliary radical. Unusual causes of peritonitis do interrupt our daily routine emergency surgical experience. Rapid recognition of the presence of peritonitis, adequate resuscitation, recognition of operative findings, establishment of biliary anatomy, and performance of a meticulous surgical procedure resulted in a good outcome.

  4. Hemoperitoneum in a peritoneal dialysis patient from a retroperitoneal source.

    Science.gov (United States)

    Balsera, Cristina; Guest, Steven

    2013-01-01

    Hemoperitoneum in peritoneal dialysis patients is a known but infrequent complication. Hemoperitoneum is more frequent in women because of its association with a variety of gynecologic presentations such as reflux menstruation, ovulation, endometrial tissue implants within the peritoneal cavity (endometriosis), and bleeding follicular cysts. Other intraperitoneal causes of hemoperitoneum include minor catheter or abdominal trauma, vascular anomalies, or hepatic or splenic cysts. Less frequently encountered is a presentation of hemoperitoneum from a retroperitoneal source. These presentations result either from peritoneal inflammation and subsequent peritoneal bleeding or retroperitoneal cavity pathology rupturing into the peritoneal cavity. Here, we present the case of a peritoneal dialysis patient presenting with hemoperitoneum several days after undergoing cardiac catheterization. The catheterization was complicated by a large retroperitoneal hematoma. Details of the case are reported, and other retroperitoneal causes of hemoperitoneum are reviewed.

    2015-08-01

    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.

    2015-01-01

    The subperitoneal space and peritoneal cavity are two mutually exclusive spaces that are separated by the peritoneum. Each is a single continuous space with interconnected regions. Disease can spread either within the subperitoneal space or within the peritoneal cavity to distant sites in the abdomen and pelvis via these interconnecting pathways. Disease can also cross the peritoneum to spread from the subperitoneal space to the peritoneal cavity or vice versa.

  12. Unmet needs in automated cytogenetics

    International Nuclear Information System (INIS)

    Though some, at least, of the goals of automation systems for analysis of clinical cytogenetic material seem either at hand, like automatic metaphase finding, or at least likely to be met in the near future, like operator-assisted semi-automatic analysis of banded metaphase spreads, important areas of cytogenetic analsis, most importantly the determination of chromosomal aberration frequencies in populations of cells or in samples of cells from people exposed to environmental mutagens, await practical methods of automation. Important as are the clinical diagnostic applications, it is apparent that increasing concern over the clastogenic effects of the multitude of potentially clastogenic chemical and physical agents to which human populations are being increasingly exposed, and the resulting emergence of extensive cytogenetic testing protocols, makes the development of automation not only economically feasible but almost mandatory. The nature of the problems involved, and acutal of possible approaches to their solution, are discussed

    The dysfunction of the catheter in peritoneal dialysis (PD) is a frequent complication. However, perforation of organs are rare, particularly that of the urinary bladder. This requires 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. PMID:22569443

    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.

    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.

  11. Peritoneum and mesenterium. Radiological anatomy and extent of peritoneal diseases

    International Nuclear Information System (INIS)

    The abdominal cavity is subdivided into the peritoneal cavity, lined by the parietal peritoneum, and the extraperitoneal space. It extends from the diaphragm to the pelvic floor. The visceral peritoneum covers the intraperitoneal organs and part of the pelvic organs. The parietal and visceral layers of the peritoneum are in sliding contact; the potential space between them is called the peritoneal cavity and is a part of the embryologic abdominal cavity or primitive coelomic duct. To understand the complex anatomical construction of the different variants of plicae and recesses of the peritoneum, an appreciation of the embryologic development of the peritoneal cavity is crucial. This knowledge reflects the understanding of the peritoneal anatomy, deep knowledge of which is very important in determining the cause and extent of peritoneal diseases as well as in decision making when choosing the appropriate therapeutic approach, whether surgery, conservative treatment, or interventional radiology.

    Full Text Available Meconium peritonitis is a sterile chemical peritonitis, which frequently occurs after intestinal perforation in utero. Overall mortality rates have drastically decreased with earlier prenatal diagnosis and improved perinatal care. However, perinatal surgical management of meconium peritonitis is largely dependent on individual surgeon experience. We present a case of meconium peritonitis with emergent cesarean section delivery after the patient developed massive meconium ascites, hydrops fetalis, and non-reassuring fetal monitoring. In the immediate post-natal period, the patient was intubated and a peritoneal drain was placed for respiratory and hemodynamic stabilization. He was then taken to the operating room the following day for laparotomy and bowel resection. His post-operative course was uneventful, and he was discharged home in good clinical condition.

    Full Text Available Abstract Background Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. We discuss one such rare case, outlining the fact that an intra-operative surprise diagnosis could have been facilitated by previous investigations. Case presentation A 56 year-old man presented in A&E department with small bowel ileus. He had a history of 6 similar episodes of small bowel obstruction in the past 4 years, which resolved with conservative treatment. Pre-operative work-up did not reveal any specific etiology. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. Conclusion Idiopathic sclerosing encapsulating peritonitis, although rare, may be the cause of a common surgical emergency such as small bowel ileus, especially in cases with attacks of non-strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel ileus combined with relevant imaging findings and lack of other plausible etiologies. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a "surprise" upon laparotomy and result in proper management.

  16. Peritoneal Dialysis Tailored to Pediatric Needs

    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.

    Full Text Available Four hundred patients who presented in the emergency of GMC Jammu as a case of perforation peritonitisover a period of two years were studied. In most of the cases diagnosis was made by clinical examinationsupplemented by investigations in the form of standing X-ray chest PA view with domes of diaphragm,Ultrasound abdomen and abdominal paracentesis. Contrast enhanced CT scans of abdomen wereconducted on patients where the diagnosis of perforation peritonitis was doubtful. After resuscitation,Laparotomy was done in all the patients and thorough peritoneal lavage was done. A note of the site,size, type, number of perforations was made and biopsy was taken from the edge of the perforationwhenever indicated. The most common cause of gastrointestinal perforation in our study was duodenalulcer perforation, followed by appendicitis, typhoid perforation, blunt/penetrating trauma, gastric perforation,obstruction, iatrogenic, malignancy, and recurrent perforation. Primary closure of the perforation wasmost commonly done procedure, followed by appendectomy, resection anastomosis of the gut andexteriorization of the gut. The overall mortality was 6 % and morbidity in the form of wound infection,fever, respiratory complications, residual abscess, dyselectrolytemia, burst abdomen, jaundice, sepsis,cardiac complications, anastomotic disruption was present

    AIM: To investigate the relationship between encapsulating peritonitis and familial Mediterranean fever (FMF). METHODS: The patient had a history of type 2 diabetes and laparoscopic cholecystectomy was performed one year ago for cholelithiasis. Eleven months after the operation she developed massive ascites. Biochemical evaluation revealed hyperglycemia, mild Fe deficiency anemia, hypoalbuminemia and a CA-125 level of 2 700 IU. Ascitic evaluation showed characteristics of exudation with a cell count of 580/mm3. Abdominal CT showed omental thickening and massive ascites. At exploratory laparotomy there was generalized thickening of the peritoneum and a laparoscopic clip encapsulated by fibrous tissue was found adherent to the uterus. Biopsies were negative for malignancy and a prophilactic total abdominal hysterectomy and bilateral salpingooophorectomy were performed. RESULTS: The histopathological evaluation was compatible with chronic nonspecific findings and mild mesothelial proliferation and chronic inflammation at the uterine serosa and liver biopsy showed inactive cirrhosis. CONCLUSION: The patient was evaluated as sclerosing encapsulating peritonitis induced by the laparoscopic clip acting as a foreign body. Due to the fact that the patient had FMF the immune response was probably exaggerated.

    2016-01-01

    Introduction: Telehealth technologies are being widely adopted across the globe for management of long-term conditions. There are limited data on its use, effectiveness and patient experience in end-stage renal disease. The aim of this pilot project was to explore patient acceptability of technology and evaluate its effect on clinical interventions and quality of life in patients undergoing peritoneal dialysis. Methods: Peritoneal dialysis patients were provided with computer tablets (PODs). PODs contained a knowledge database with treatment- and symptom-based questionnaires that generated alerts for the clinical team. Alerts were reviewed daily and followed up by a telephone call or clinic visit. Interventions were at the discretion of clinicians. Data were recorded prospectively and quality of life and Quebec User Evaluation of Satisfaction with assistive Technology questionnaires evaluated at the start and end of the programme. Results: In all, 22 patients have participated over 15 months. The mean age was 61.6 years and PODs were utilised for an average of 341.9 days with 59.1% choosing to continue beyond the study period. We received a total of 1195 alerts with an average of 2.6 alerts per day. A total of 36 admissions were avoided and patients supported to self-manage on 154 occasions. Quebec User Evaluation of Satisfaction with assistive Technology scores remained high throughout the programme although no improvement in quality of life was seen. Discussion: Telehealth is useful to monitor patients with renal failure on peritoneal dialysis. It is acceptable across age groups and provides an additional resource for patients to self-manage. Satisfaction scores and retention rates suggest a high level of acceptability.

    Full Text Available Gastrointestinal complications are common among patients on peritoneal dialysis. 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

    Microbiological documentation of peritoneal candidiasis (PC) is hampered by the low numbers of yeasts observable by direct microscopic examination and recoverable by culture methods. The performance of a polymerase chain reaction (PCR) DNA Low-Density Microarray System (CLART STIs B) was compared to that of BACTEC FX automated culture method for the detection of Candida spp. in 161 peritoneal fluids (PF) from patients with peritonitis. The clinical utility of (1-3)-β-d-glucan (BDG) antigenemia in the diagnosis of PC was evaluated in 42 of these patients. The overall agreement between the PCR assay and the culture method was good (κ = 0.790), and their sensitivities were 93.5% and 74.19%, respectively. Serum BDG levels in patients with Candida spp. in PFs (median, 200.3 pg/mL; Range, 22.0-523.4 pg/mL) was significantly higher (P = 0.002) than those found in patients without the yeast (median, 25.3 pg/mL; Range, 0-523.4 pg/mL). Our study demonstrates the potential clinical utility of molecular methods and the measurement of serum BDG levels for the diagnosis of PC.

    Acute renal failure (ARF) in adults in the intensive care unit (ICU) often evolves in a context of multiple organ failure, which explains the high mortality rate and increase treatment needs. Among, two modalities of renal replacement therapy, peritoneal dialysis (PD) was the first modality used for the treatment of ARF in the 1950s. Today, while PD is generalized for chronic renal failure treatment, its use in the ICU is limited, particularly, due to the advent of new hemodialysis techniques and the development of continuous replacement therapy. Recently, a renewed interest in the use of PD in patients with ARF has manifested in several emerging countries (Brazil, Vietnam). A systematic review in 2013 showed a similar mortality in ARF patients having PD (58%) and those treated by hemodialysis or hemodiafiltration/hemofiltration (56.1%). In the International society of peritoneal dialysis (ISPD)'s guideline (2013), PD may be used in adult ARF as the other blood extracorporeal epuration technics (recommendation with grade 1B). PD is the preferred method in cardiorenal syndromes, in frailty patients with hemodynamic instability and those lacking vascular access; finally PD is also an option in elderly and patients with bleeding tendency. In industrial countries, high volume automated PD with a flexible catheter (usually Tenckhoff) is advocated.

    Postoperative peritonitis (POP) is a common surgical complication after bariatric surgery (BS). We assessed the importance of positive fungal cultures in these cases of POP admitted to the intensive care unit. Clinical features and outcome were compared in 25 (41%) Candida-positive patients (6 (22%) fluconazole-resistant Candida glabrata) and 36 patients without Candida infection. Candida infections were more commonly isolated in late-onset peritonitis and were often associated with multidrug-resistant bacteria. Risk factors for intensive care unit mortality (19.6%) were diabetes and superobesity. Candida infections, including fluconazole-resistant strains, are common in POP after BS. These data encourage the empirical use of a broad-spectrum antifungal agent.

    Planning for effective software engineering is not easy, and software project managers would usually welcome assistance in this area. Very effective assistance could be provided by automated tools that are decision aids. However, a comprehensive suite of such tools does not yet exist. One area that has been addressed is the selection of a programming language. This paper discusses in detail a decision tool that has been developed for language selection. It also addresses the areas in which other such tools are required.

    Twenty one cases of appendiceal peritonitis in children are reviewed. An antibiotic (sodium cefoxitine) has been used during the post-operative course to decrease the risk of suppurative complications. Cultures obtained from peritoneal exudate yielded "E. coli" and "Bacteroides" sp. as the most commonly isolated bacteria. External drainage was placed as a rutine and the percentage of suppurative complications was 14%. No patient showed evidence of adverse reactions to the antibiotic and the mortality of the serie was zero. Obtained results allow to state that cefoxitine is effective in the management of appendiceal peritonitis in children.

    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.

    2015-12-01

    Spontaneous bacterial peritonitis (SBP) is a severe complication occurring in patients with cirrhosis, and is associated with high mortality. Liver transplantation should be considered after a first episode of SBP. Gram-negative bacilli are the major cause of SBP, however there is an increasing trend of Gram-positive cocci related SBP. Management includes empirical antibiotic treatment and albumin infusion. The choice of antibiotics depends on the site of acquisition (community-acquired vs nosocomial or health-care associated infection) and local resistance profile, due to the emergence of drug-resistant bacteria. Secondary prophylaxis is recommended after resolution of SBP and reduces recurrence and mortality. Primary prophylaxis in patients with low protein ascites (<15 g/L) should be restricted to patients with severe cirrhosis awaiting for liver transplantation.

  11. Oral Tori in Chronic Peritoneal Dialysis Patients.

    Chia-Lin Hsu

    Full Text Available The pathogenesis of oral tori has long been debated and is thought to be the product of both genetic and environmental factors, including occlusal forces. Another proposed mechanism for oral tori is the combination of biomechanical forces, particularly in the oral cavity, combined with cortical bone loss and trabecular expansion, as one might see in the early stages of primary hyperparathyroidism. This study investigated the epidemiology of torus palatinus (TP and torus mandibularis (TM in peritoneal dialysis patients, and analyzed the influences of hyperparathyroidism on the formation of oral tori.In total, 134 peritoneal dialysis patients were recruited between July 1 and December 31, 2015 for dental examinations for this study. Patients were categorized into two subgroups based on the presence or absence of oral tori. Demographic, hematological, biochemical, and dialysis-related data were obtained for analysis.The prevalence of oral tori in our sample group was high at 42.5% (57 of 134, and most patients with oral tori were female (61.4%. The most common location of tori was TP (80.7%, followed by TP and TM (14.0%, then TM (5.3%. All 54 TP cases were at the midline, and most were <2 cm (59.3%, flat (53.7%, and located in the premolar region (40.7%. Of the 11 TM cases, all were bilateral and symmetric, mostly <2 cm (81.9%, lobular (45.4%, and located at premolar region (63.6%. Interestingly, patients with oral tori had slightly lower serum levels of intact parathyroid hormones than those without oral tori, but the difference was not statistically significant (317.3±292.0 versus 430.1±492.6 pg/mL, P = 0.126. In addition, patients with oral tori did not differ from patients without tori in inflammatory variables such as serum high sensitivity C-reactive protein levels (6.6±8.2 versus 10.3±20.2 mg/L, P = 0.147 or nutritional variables such as serum albumin levels (3.79±0.38 versus 3.77±0.45 g/dL, P = 0.790.

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

  13. Experimental Trichinellosis in rats: Peritoneal macrophage activity

    Gruden-Movsesijan Alisa

    2010-01-01

    Full Text Available The influence of Trichinella spiralis infection on macrophage activity in rats during the first 28 days of infection was examined by measuring the production of NO and IL-6, as well as the expression of mannose receptor on the surface of peritoneal macrophages. During the course of a dynamic shift in the 3 life-cycle stages of the parasite, intermittent variations in NO production were observed but ended with increased values that coincided with the highest values for IL-6 release in the final, muscle phase of infection. No change in mannose receptor expression was observed during the course of infection. These results confirm that the Trichinella spiralis infection provokes changes in macrophage activity that could influence not only the course of the parasitic disease but also the overall immune status of the host.

    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 Introduction: Renal failure affects the mechanical and the ventilatory function of the lungs. A few studies have evaluated the ventilatory and pulmonary function in dialysis patients. The present study aimed to compare Pulmonary Function Test (PFT results in patients undergoing Hemodialysis (HD and Peritoneal Dialysis (PD. Materials and Methods: We conducted a cross-sectional study on 50  patients with hemodialysis (HD and 50 cases with PD who  underwent PFT in Ghaem and Imam Reza hospitals Mashhad, Iran from November 2010 to July 2012. Spirometric parameters including forced expiratory volume in 1s (FEV1, FEV1/forced vital capacity (FVC, forced expiratory flow 25-75% (FEF and peak expiratory flow (PEF were compared between the two groups of patients. Results: Approximately 68% of the HD patients, 66% of the PD patients, and 67% of all the studied cases showed a normal spirometric pattern. Moreover, there were no significant differences between the two groups considering the mean of the aforementioned spirometric parameters(restrictive ,obstructive pattern (P=0.969. However, an insignificant inverse correlation was observed between the duration of dialysis with FEV1 (r=0.381, P=0.008, FVC (r=-0.298, P=0.04, FEF 25-75% (r=0.43, P=0.003, PEF (r= 0.349, P=0.02 and FEV1/FVC (r=-0.363, P=0.01, in the HD patients and between the patients’ age with FEV1/FVC (r=0.03, P=0.02 in the PD patients. Conclusion: This study showed no significant difference in pulmonary function in hemo and peritoneal dialysis,so according this result ,both of the dialysis had the same affect on the lung function.

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 OBJECTIVE: The objective of this study was to examine the effects of angiotensin-converting enzyme inhibitors on peritoneal membrane transport, peritoneal protein loss, and proteinuria in peritoneal dialysis patients. METHODS: Fifty-four peritoneal dialysis patients were included in the study. The patients were divided into two groups. Group 1 (n = 34 was treated with angiotensin-converting enzyme inhibitors. Group 2 (n = 20 did not receive any antihypertensive drugs during the entire follow-up. Eleven patients were excluded from the study thereafter. Thus, a total of 30 patients in Group 1 and 13 patients in Group 2 completed the study. We observed the patients for six months. Group 1 patients received maximal doses of angiotensin-converting enzyme inhibitors for six months. Parameters at the beginning of study and at the end of six months were evaluated. RESULTS: At the end of six months, total peritoneal protein loss in 24-hour dialysate effluent was significantly decreased in Group 1, whereas it was increased in Group 2. Compared to the baseline level, peritoneal albumin loss in 24-hour dialysate effluent and 4-hour D/P creatinine were significantly increased in Group 2 but were not significantly changed in Group 1. A covariance analysis between the groups revealed a significant difference only in the decreased amount of total protein loss in 24-hour dialysate. Proteinuria was decreased significantly in Group 1. CONCLUSION: This study suggests that angiotensin-converting enzyme inhibitors reduce peritoneal protein loss and small-solute transport and effectively protect peritoneal membrane transport in peritoneal dialysis patients.

    Laparoscopic inguinal herniorraphy is a commonly performed procedure given the reported decrease in pain and earlier return to activity when compared with the open approach. Moreover, robotic assistance offers the operating surgeon considerable ergonomic advantages, making it an attractive alternative to conventional laparoscopic herniorraphy. Robotic herniorraphy utilizes the transabdominal preperitoneal approach where following repair peritoneal closure is necessary to avoid mesh exposure to the viscera. Self-anchoring sutures are frequently used to this end given the ease of use and knotless application. We present an unusual case of post-operative small bowel obstruction following robotic inguinal hernia repair caused by the self-anchoring suture used for peritoneal closure. This patient presented 3 days post-procedure with symptoms and cross-sectional imaging indicative of small bowel obstruction with a clear transition point. Underwent laparoscopic lysis of a single adhesive band originating from the loose intraperitoneal end of the suture leading to resolution of symptoms. PMID:27340230

  19. Regulation of Synthesis and Roles of Hyaluronan in Peritoneal Dialysis

    2015-01-01

    Full Text Available Hyaluronan (HA is a ubiquitous extracellular matrix glycosaminoglycan composed of repeated disaccharide units of alternating D-glucuronic acid and D-N-acetylglucosamine residues linked via alternating β-1,4 and β-1,3 glycosidic bonds. HA is synthesized in humans by HA synthase (HAS enzymes 1, 2, and 3, which are encoded by the corresponding HAS genes. Previous in vitro studies have shown characteristic changes in HAS expression and increased HA synthesis in response to wounding and proinflammatory cytokines in human peritoneal mesothelial cells. In addition, in vivo models and human peritoneal biopsy samples have provided evidence of changes in HA metabolism in the fibrosis that at present accompanies peritoneal dialysis treatment. This review discusses these published observations and how they might contribute to improvement in peritoneal dialysis.

    BACKGROUND: Primary myeloifbrosis (PMF) is a myelopro-liferative disorder characterized by bone marrow ifbrosis. Extra-medullary hematopoiesis sometimes occurs even in the peritoneal cavity, apart from organs such as the liver, spleen, and lymph nodes. This may sometimes be complicated by spontaneous infection and complications. We report a rather unusual case of PMF, who presented as an emergency with spontaneous peritonitis to general surgery department and had a fulminant clinical course. METHOD: A clinical case note review was done and a literature search was undertaken. RESULTS: A rather unusual case of PMF, who presented as an emergency with spontaneous peritonitis to general surgery department. The patient underwent a laparotomy and had a fulminant clinical course. CONCLUSIONS: Peritonitis in myeloifbrosis may have a number of causes. Clinicians need to be aware of them and provide conservative management prior to surgical treatment.

    Full Text Available Automated Essay Scoring Semire DIKLI Florida State University Tallahassee, FL, USA ABSTRACT The impacts of computers on writing have been widely studied for three decades. Even basic computers functions, i.e. word processing, have been of great assistance to writers in modifying their essays. The research on Automated Essay Scoring (AES has revealed that computers have the capacity to function as a more effective cognitive tool (Attali, 2004. AES is defined as the computer technology that evaluates and scores the written prose (Shermis & Barrera, 2002; Shermis & Burstein, 2003; Shermis, Raymat, & Barrera, 2003. Revision and feedback are essential aspects of the writing process. Students need to receive feedback in order to increase their writing quality. However, responding to student papers can be a burden for teachers. Particularly if they have large number of students and if they assign frequent writing assignments, providing individual feedback to student essays might be quite time consuming. AES systems can be very useful because they can provide the student with a score as well as feedback within seconds (Page, 2003. Four types of AES systems, which are widely used by testing companies, universities, and public schools: Project Essay Grader (PEG, Intelligent Essay Assessor (IEA, E-rater, and IntelliMetric. AES is a developing technology. Many AES systems are used to overcome time, cost, and generalizability issues in writing assessment. The accuracy and reliability of these systems have been proven to be high. The search for excellence in machine scoring of essays is continuing and numerous studies are being conducted to improve the effectiveness of the AES systems.

    Long-term peritoneal dialysis therapy causes inflammation and histological changes in the peritoneal membrane. Inflammation generally activates fibroblasts and results in fibroblast-myofibroblast differentiation. Heat-shock protein 47 (HSP 47), a collagen-specific molecular chaperone, is localized in myofibroblasts and is involved in the progression of peritoneal fibrosis. Daikenchuto (DKT), a Kampo medicine, is used to prevent postoperative colon adhesion. It inhibits inflammation and HSP 47 expression in the gastrointestinal tract. We examined the effect of DKT on chlorhexidine gluconate (CG)-induced peritoneal fibrosis in mice injected with 0.1% CG dissolved in 15% ethanol. DKT was dissolved in the drinking water. Histological changes were assessed using Masson trichrome staining. Cells expressing α-smooth muscle actin (α-SMA), HSP 47, phospho-Smad 2/3, F4/80, and monocyte chemotactic protein-1 were examined immunohistochemically. Compared with the control group, the peritoneal tissues of the CG group were markedly thickened, and the number of cells expressing α-SMA, HSP 47, phospho-Smad 2/3, F4/80, and monocyte chemotactic protein-1 was significantly increased. However, these changes were inhibited in the DKT-treated group. These results indicate that DKT can prevent peritoneal fibrosis by inhibiting inflammation and HSP 47 expression. PMID:25747978

    Background:High peritoneal transport status was previously thought to be a poor prognostic factor in peritoneal dialysis (PD) patients.However,its effect on diabetic nephropathy PD patients is unclear in consideration of the adverse impact of diabetes itself.The purpose of this study was to investigate the influence of peritoneal transport characteristics on nutritional status and clinical outcome in diabetic nephropathy patients on PD.Methods:One hundred and two diabetic nephropathy patients on PD were enrolled in this observational cohort study.According to the initial peritoneal equilibration test result,patients were divided into two groups:Higher transport group (HT,including high and high average transport) and lower transport group (LT,including low and low-average transport).Demographic characteristics,biochemical data,dialysis adequacy,and nutritional status were evaluated.Clinical outcomes were compared.Risk factors for death-censored technique failure and mortality were analyzed.Results:Compared with LT group (n =37),serum albumin was significantly lower and the incidence of malnutrition by subjective global assessment was significantly higher in HT group (n =65) (P < 0.05).Kaplan-Meier analyses showed that death-censored technique failure and mortality were significantly increased in HT group compared with that in LT group.On multivariate Cox analyses,higher peritoneal transport status and lower residual renal function (RRF) were independent predictors of death-censored technique failure when adjusted for serum albumin and total weekly urea clearance (Kt/V).Independent predictors of mortality were advanced age,anemia,hypoalbuminemia,and lower RRF,but not higher peritoneal transport status.Conclusions:Higher peritoneal transport status has an adverse influence on nutrition for diabetic nephropathy patients on PD.Higher peritoneal transport status is a significant independent risk factor for death-censored technique failure,but not for mortality in

    Fungal infections have a high incidence in patients receiving peritoneal dialysis. (1)
Peritoneal dialysis is often complicated by peritonitis which has only minimally mycotic etiology, but nonetheless it is associated with 15-45% mortality (8).
 The opportunistic pathogens such as Candida can cause infection in immunocompromised conditions. Even the Acinetobacter tends to infect immunocompromised individuals and it has the same risk factors for infection as Candida: immunosuppression, malignancy, HIV positivity and all the other conditions of immunosuppression, central venous catheterization, mechanical ventilation and prolonged antibiotic therapy. The sepsis by Acinetobacter predicts a negative prognosis with the mortality rate between 20 to 60% (12), especially in cases of isolation of multi-resistant germs.
 We present a case report of a CKD patient undergoing peritoneal dialysis therapy who was hospitalized for acute pancreatitis, later complicated by the development of pancreatic pseudocysts, C. albicans peritonitis with hematologic spread of the fungus, superimposed Acinetobacter baumannii sepsis and pneumonia. She has been subjected to percutaneous drainage of pseudocysts, to switch from peritoneal dialysis to hemodialysis, to various evacuative thoracentesis, and to polymicrobial therapy (meropenem, teicoplanina, tigeciclina, linezolid, colimicina, fluconazolo, etc.) that allowed the resolution of sepsis. The peculiarity of this case is represented by the numerous morbidity that the patient developed simultaneously, with the genesis of a complex clinical picture, by the combination of infections due to Candida albicans and Acinetobacter baumannii. Successful treatment strategies allowed to fight and cure a medical condition associated with a high mortality rate. PMID:26845211

    Feline infectious peritonitis (FIP) is caused by feline coronaviruses (FCoVs) and represents one of the most important lethal infectious diseases of cats. To date, there is no efficacious prevention and treatment, and our limited knowledge on FIP pathogenesis is mainly based on analysis of experiments with field isolates. In a recent study, we reported a promising approach to study FIP pathogenesis using reverse genetics. We generated a set of recombinant FCoVs and investigated their pathogenicity in vivo. The set included the type I FCoV strain Black, a type I FCoV strain Black with restored accessory gene 7b, two chimeric type I/type II FCoVs and the highly pathogenic type II FCoV strain 79-1146. All recombinant FCoVs and the reference strain isolates were found to establish productive infections in cats. While none of the type I FCoVs and chimeric FCoVs induced FIP, the recombinant type II FCoV strain 79-1146 was as pathogenic as the parental isolate. Interestingly, an intact ORF 3c was confirmed to be restored in all viruses (re)isolated from FIP-diseased animals.

    Feline infectious peritonitis (FIP) infection resulting in clinical signs is invariably fatal despite clinical intervention. As FIP is an immune-mediated disease, treatment is mainly aimed at controlling the immune response triggered by the infection with the feline coronavirus (FCoV). Immune suppressive drugs such as prednisone or cyclophosphamide may slow disease progression but do not produce a cure. In nearly every published case report of attempted therapy for clinical FIP, glucocorticoids have been used; there are, however, no controlled studies that evaluate the effect of glucocorticoids as a therapy for FIP. Some veterinarians prescribe immune modulators to treat cats with FIP with no documented controlled evidence of efficacy. It has been suggested that these agents may benefit infected animals by restoring compromised immune function, thereby allowing the patient to control viral burden and recover from clinical signs. However, a non-specific stimulation of the immune system may be contraindicated as clinical signs develop and progress as a result of an immune-mediated response to the mutated FCoV.

  7. Feline infectious peritonitis: still an enigma?

    2014-03-01

    Feline infectious peritonitis (FIP) is one of the most important fatal infectious diseases of cats, the pathogenesis of which has not yet been fully revealed. The present review focuses on the biology of feline coronavirus (FCoV) infection and the pathogenesis and pathological features of FIP. Recent studies have revealed functions of many viral proteins, differing receptor specificity for type I and type II FCoV, and genomic differences between feline enteric coronaviruses (FECVs) and FIP viruses (FIPVs). FECV and FIP also exhibit functional differences, since FECVs replicate mainly in intestinal epithelium and are shed in feces, and FIPVs replicate efficiently in monocytes and induce systemic disease. Thus, key events in the pathogenesis of FIP are systemic infection with FIPV, effective and sustainable viral replication in monocytes, and activation of infected monocytes. The host's genetics and immune system also play important roles. It is the activation of monocytes and macrophages that directly leads to the pathologic features of FIP, including vasculitis, body cavity effusions, and fibrinous and granulomatous inflammatory lesions. Advances have been made in the clinical diagnosis of FIP, based on the clinical pathologic findings, serologic testing, and detection of virus using molecular (polymerase chain reaction) or antibody-based methods. Nevertheless, the clinical diagnosis remains challenging in particular in the dry form of FIP, which is partly due to the incomplete understanding of infection biology and pathogenesis in FIP. So, while much progress has been made, many aspects of FIP pathogenesis still remain an enigma.

    Faced with a downsizing organization, serious budget reductions and retirement of key metrology personnel, maintaining capabilities to provide necessary services to our customers was becoming increasingly difficult. It appeared that the only solution was to automate some of our more personnel-intensive processes; however, it was crucial that the most personnel-intensive candidate process be automated, at the lowest price possible and with the lowest risk of failure. This discussion relates factors in the selection of the Standard Leak Calibration System for automation, the methods of automation used to provide the lowest-cost solution and the benefits realized as a result of the automation.

    Peritoneal dialysis (PD) is a common treatment for patients with reduced or absent renal function. Long-term PD leads to peritoneal injury with structural changes and functional decline. At worst, peritoneal injury leads to encapsulating peritoneal sclerosis (EPS), which is a serious complication of PD. In order to carry out PD safely, it is important to define the mechanism of progression of peritoneal injury and EPS. We prepared rat models of peritoneal injury by intraperitoneal administrat...

    Surgery is often the first therapeutic indication in cancer. Patient survival essentially depends on the completeness of tumor resection. This is a major challenge, particularly in patients with peritoneal carcinomatosis (PC), where tumors are widely disseminated in the large peritoneal cavity. These small tumors can be difficult to visualize and are often positioned in delicate locations, further increasing the risk of producing serious tissue/organ damage during their ablation. We propose an innovative therapeutic approach based on intraoperative fluorescence (IF) guided electrochemotherapy (ECT) for the treatment of peritoneal micro-metastases. ECT combines the effects of tissue electro-permeabilization (EP) with the administration of an antimitotic agent (bleomycin) that has poor permeability across intact membranes. IF significantly improves the detection of small tumor lesions. ECT is clinically validated for the treatment of cutaneous tumors in animals and humans, but this is the first time that it has been used along with IF imaging for the targeted treatment of peritoneal metastases in a preclinical model. We set up a murine model of PC that develops secondarily to the resection of a distant primary tumor. Tumor growth and metastasis were finely monitored by non-invasive multimodal imaging (bioluminescence and 3D fluorescence/microCT). Once metastases were detected, mice were randomized into three groups: the ECT group (bleomycin injected intravenously followed by EP) and 2 control groups (bleomycin alone and EP alone). Twenty four hours after the intravenous injection of the tumor targeting agent Angiostamp™700, mice in all groups underwent an abdominal surgery for metastases exploration assisted by fluorescence imaging with the Fluobeam®700 portative device. EP was applied to every nodule detected by IF, except in the bleomycin control group. After surgery, the metastatic invasion was tracked by bioluminescence imaging. In mice treated with bleomycin

    This study aims to develop a prototype for an Automated Car Park Management System that will increase the quality of service of parking lots through the integration of a smart system that assists motorist in finding vacant parking lot. The research was based on implementing an operating system and a monitoring system for parking system without the use of manpower. This will include Parking Guidance and Information System concept which will efficiently assist motorists and ensures the safety of the vehicles and the valuables inside the vehicle. For monitoring, Optical Character Recognition was employed to monitor and put into list all the cars entering the parking area. All parking events in this system are visible via MATLAB GUI which contain time-in, time-out, time consumed information and also the lot number where the car parks. To put into reality, this system has a payment method, and it comes via a coin slot operation to control the exit gate. The Automated Car Park Management System was successfully built by utilizing microcontrollers specifically one PIC18f4550 and two PIC16F84s and one PIC16F628A.

    Full Text Available Background/Aims: Continuous ambulatory peritoneal dialysis (CAPD induces structural changes in the peritoneal membrane such as fibrosis, vasculopathy and angioneogenesis with a reduction in ultrafiltration capacity. Leukotriene (LT receptor antagonists have been found to be effective to prevent fibrosis in some nonperitoneal tissues. The aim of this study is to investigate the possible beneficial effect of montelukast, a LT receptor antagonist, on peritoneal membrane exposed to hypertonic peritoneal dialysis in uremic rats. Methods: Of the 48 male, 5/6 nephrectomized Wistar rats 29 remained alive and were included in the study. These studied rats were divided into 3 groups: Group I (n=7 was the control group, Group II (n=8 was treated with 20 ml hypertonic PDF intraperitoneally daily and Group III was treated with montelukast and similar PDF treatment protocol. The morphological and functional changes in the peritoneal membrane as well as cytokine expression were compared between groups. Results: Submesothelial thickness and the severity of the degree of hyaline vasculapathy were more prominent in group III when compared to group I. There were no significant differences between group II and other groups in terms of submesothelial thickness and the severity of the degree of hyaline vasculapathy. Increased expressions of TGF-β and VEGF in parietal peritoneal membrane were found in group II and group III when compared to group I. The amount of TGF-β and VEGF expression were similar in group II and group III. Conclusion: This study suggests that montelukast treatment does not prevent the peritoneal membrane from deleterious effects of hyperosmolar PDF in the uremic environment.

    BACKGROUND The clinical manifestations of amyloidosis depend on the type of insoluble protein as well as the location of amyloid deposits in tissues or organs. In the gastrointestinal tract, the small intestine is the most common site of amyloid deposits, whereas peritoneal involvement and ascites are rare. CASE REPORT We report on a case of ascites due to peritoneal amyloidosis. A 65-year-old patient was admitted to our institution due to anasarca and pulmonary congestion, mimicking heart failure. We started the patient on diuretics and vasodilators. Despite improvement in pulmonary congestion and peripheral edema, his ascites was not reduced. Echocardiogram revealed restrictive cardiomyopathy and a speckle-tracking pattern suggestive of cardiac amyloidosis. Subcutaneous and peritoneal biopsies revealed amyloidosis. CONCLUSIONS Amyloidosis is rare in the peritoneum and is usually asymptomatic. Ascites occurs in only 20% of patients with peritoneal amyloidosis. We searched PubMed using "ascites" and "amyloidosis" and identified only eight case reports of amyloidosis with ascites. Physicians should be particularly careful in heart failure and anasarca cases when ascites is disproportional or not responsive to diuretic treatment. To date, there is no specific treatment for peritoneal amyloidosis. PMID:27353538

  16. Percutaneous placement of peritoneal port-catheter in oncologic patients

    International Nuclear Information System (INIS)

    The aim of this paper is to describe the technique of percutaneous ultrasound (US)-guided placement of a peritoneal port-catheter in an interventional radiological setting. Nineteen patients with peritoneal carcinomatosis were selected for intraperitoneal port-catheter placement in order to perform intracavitary receptor-immuno- or radio-immunotherapy with Ytrium-90. All the procedures were performed percutaneously under US and fluoro guidance; the insertion site for catheters was chosen according to abdominal conditions and US findings: all devices were implanted at the lower abdominal quadrants. All patients were followed up with CT and US according to the therapy protocol. The procedure was successfully completed in 15/19 patients, in 4 being contraindicated by peritoneal adhesions. No procedure-related complications and device occlusions during therapy were observed; one catheter displaced 7 months later the placement. In our experience, this procedure was feasible, reliable and easy to perform, allowing the correct administration of the planned intracavitary therapy. Peritoneal adhesions are the main limitation of peritoneal port placement. (orig.)

  18. Peritoneal sepsis: re laparotomy characteristic patient

    International Nuclear Information System (INIS)

    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

    Anemia is highly prevalent among chronic kidney disease (CKD) patients and patients receiving renal replacement therapy. In this paper we will outline the prevention and treatment of anemia in patients treated with peritoneal dialysis (PD). PD patients are less anemic and more sensitive to erythropoesis-stimulating agent (ESA) than their hemodialysis (HD) counterparts and, in general, dosages required for achieving similar hemoglobin levels to those achieved in HD patients are remarkably less. Before starting with ESA treatment we have to evaluate the degree of anemia and excluded other causes which are not connected with CKD and method of treatment. Patient's compliance is crucial for a successful therapy and it can be improved by decreasing frequency of administration of ESA. Since ESAare expensive, "cost-effectivnes" studies represent an important factor in choosing a distinct drug. Subcutaneous administration provides better long-term utilization of ESA in comparison to intravenous administration and is therefore preferred in PD patients. Intraperitoneal administration is not recommended due to poor bioavailability. In some patients we can observe the reduced response to ESA therapy. The definition of reduced response is generally regarded as a failure to achieve target hemoglobin concentration of >11 g/dL. Identification of underlying cause is not always easy but every attempt should be made to investigate every patient with resistance to therapy because some causes are easily corrected. Since 2005 particular ESA drugs have been approved by Croatian Institute for Health Insurance and registered for use in Croatia. For PD patients the ESAcan be prescribed by general practitioner. The list of available drugs is available in the official government newspaper Nardone novine No.27, March 2nd, 2009. PMID:20232548

    Quantitative bacteriology in peritoneal exudate was studied in 40 patients with generalized peritonitis of small intestinal, appendicular or colonic origin. Bacterial growth kinesis was measured in 28 of the patients. Systemic antibiotics given before operation resulted in a significant reduction in both the concentration and growth rate of viable bacteria in the peritoneal fluid. Lavage of the peritoneal cavity with saline resulted in a further reduction in growth rate in patients given pre-operative systemic antibiotics by an effect attributable to simple dilution. In contrast, peritoneal lavage with tetracycline (1 mg/ml) resulted in complete inhibition of bacterial growth in the residual peritoneal fluid. These observations support the policy of giving systemic antibiotics to patients with generalized peritonitis as soon as the diagnosis has been made and provide bacteriological evidence for the value of peroperative antibiotic peritoneal lavage.

    The risk factors of the dialysis peritonitis occurrence were determined in patients with chronic renal disease, to whom a substitute renal therapy, using peritoneal dialysis, was conducted. The results of a three-year prospective investigation and treatment of 73 patients in Kyiv City Oleksandrivska Clinical Hospital on the base of the general surgery and nephrology departments in 2007 - 2010 yrs were studied. The dialysis peritonitis (first episode) have occurred in 42 (57.5%) patients. Cumulative rate of a dialysis peritonitis in accordance to a censored data (the dialysis peritonitis suspension or other causes) have constituted 67.7%. Due to the dialysis peritonitis occurrence the peritoneal dialysis was stopped in 14 (19.2%) patients. The obesity, raising of a serum albumin level, constipation, preliminary injection into the site of the catheter exit site we consider a risk factors for the dialysis peritonitis occurrence.

    Three children (2 girls and 1 boy) with end-stage renal failure were put in program of continuous ambulatory peritoneal dialysis in the period of 2.5 years (January 1995-September 1997). The age of the children at the treatment onset was 5-12 years. One of three children died due to cardiovascular failure after six-month treatment. Two out of three children had a total of 8 episodes of peritonitis in the period of 37 months during the treatment with peritoneal dialysis. The incidence of peritonitis occurrence in our patients was one episode in 4 patients/months. Most frequent cause for peritonitis occurrence was Staphylococcus aureus in 50% of isolated bacteria. Obtained results in peritoneal equilibration test revealed that the transport and ultrafiltration rate of peritoneal membrane decreased after recurrent peritonitis episodes.

    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

    Background Extra glucose load in peritoneal dialysis is an important cause of newly-occurred diabetic mellitus, which initiates insulin treatment in some of the dialytic patients.The purpose of this study was to discuss the influence of the peritoneal transfer status on fasting blood glucose in non-diabetic nephropathy patients who are on continuous ambulatory peritoneal dialysis (CAPD).Methods One hundred and forty-five patients with total KT/V per week over 2.0 were recruited, including 60 males and 85 females. Fasting blood glucose (FBG), creatinine, blood urea nitrogen (BUN), blood albumin, blood lipid profile and blood C-reactive protein (CRP) were analyzed at the beginning of the peritoneal dialysis and after 12 months. A peritoneal equilibration test (PET) was carried out at the 3rd month of CAPD, and meantime residual renal function, peritoneal solute clearance rate, ultrafiltration volume and urine volume were also evaluated.Results Twenty-one cases were identified as a low transfer group (L), 32 cases as a low average transfer group (LA), 58 cases as a high average transfer group (HA) and 34 cases as a high transfer group (H). At the end of the 12th month, 83 cases had elevated FBG Through stepwise multiple regression analysis we found the FBG level in these patients was positively related to glucose load and CRP, and negatively related to glucose absorption in the peritoneum (D/D_0) and blood albumin (P<0.05). Kaplan-Meier analysis during a 48-month follow-up found the morbidity of hyperglycemia to be 17/34 cases (50.1%) in the high transfer group, 20/58 cases (34.5%) in the high average transfer group, 11/32 cases (34.3%) in the low average transfer group, and 1/21 cases (5.4%) in the low transfer group.Conclusions Patients with high peritoneal transfer capacity might have the highest morbidity from hyperglycemia among patients with these four different peritoneal transfer status. Glucose load, baseline CRP and FBG level before peritoneal dialysis, and

    Background. Patients with peritoneal dialysis-related peritonitis usually have different responses to initial antibiotic treatment. This study aimed to explore the patterns of response by using the changes of dialysate white blood cell count on the first five days of the initial antibiotic treatment. Materials and Methods. A retrospective cohort study was conducted. All peritoneal dialysis-related peritonitis episodes from January 2014 to December 2015 were reviewed. We categorized the patterns of antibiotic response into 3 groups: early response, delayed response, and failure group. The changes of dialysate white blood cell count for each pattern were determined by multilevel regression analysis. Results. There were 644 episodes in 455 patients: 378 (58.7%) of early response, 122 (18.9%) of delayed response, and 144 (22.3%) of failure episodes. The patterns of early, delayed, and failure groups were represented by the average rate reduction per day of dialysate WBC of 68.4%, 34.0%, and 14.2%, respectively (p value < 0.001 for all comparisons). Conclusion. Three patterns, which were categorized by types of responses, have variable rates of WBC declining. Clinicians should focus on the delayed response and failure patterns in order to make a decision whether to continue medical therapies or to aggressively remove the peritoneal catheter.

    Full Text Available Background: Tuberculous peritonitis (TBP is a well-known complication of ventriculo-peritoneal (VP shunt treatment for hydrocephalus resulting from tuberculous meningitis (TBM. However, a case of hydrocephalus unrelated to TBM resulting from VP shunt malfunction due to TBP has not been reported. Case Description: A 21-year-old male presented with nausea, abdominal pain, and headache. VP and cysto-peritoneal (CP shunts had been inserted to treat hydrocephalus due to a suprasellar arachnoid cyst, replaced the VP and removed the CP in his childhood. Computed tomography demonstrated acute hydrocephalus and an abdominal pseudocyst surrounding the distal end of the peritoneal tube. Initial laboratory data showed elevated white blood cell count and C-reactive protein level, but no causative pathogen was identified. External drainage of cerebrospinal fluid (CSF and of the fluid in the peritoneal cyst was established, and empirical antibiotic therapy was initiated. Bacterial cultures eventually revealed Mycobacterium tuberculosis infection, and TBP was diagnosed. The patient responded well to antituberculosis (anti-TB agents and insertion of a ventriculo-pleural shunt. Conclusion: This case highlights the possibility of CSF shunt failure and concomitant neurological sequelae from TB infection even when the pathogen has not invaded the central nervous system, as in TBM. Moreover, TBP is rare in developed countries and therefore may be misdiagnosed because of nonspecific clinical features and low sensitivity of common TB screening methods.

    2008-11-01

    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.

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

    International Nuclear Information System (INIS)

    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

    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

    A 14-year-old girl, with end-stage renal disease on continuous ambulatory peritoneal dialysis (CAPD) the last 4 years, after an episode of Candida albicans was switched to hemodialysis. One month later she came back because of a palpable painful abdominal mass and abdominal distention. Computed tomography (CT) and ultrasound examination demonstrated a demarkated fluid collection in the lower abdomen and pelvis. The cyst was drained percutaneously and the culture disclosed candida albicans which was treated with fluconasole. Two months later, the girl was admitted again with the same symptoms. An investigative laparotomy was undergone and the cyst was drained again. Fluid cultures were negative. CT abdomen examination six months later was negative for cyst relapse. In conclusion, intraperitoneal pseudocyst is a serious complication of CAPD. Surgical intervention may be preferable to percutaneous drainage. PMID:19582199

    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.

    Spontaneous bacterial peritonitis is caused by infection of ascitic fluid without any apparent intraabdominal source of infection. The disease most commonly occurs in patients with cirrhosis and 70% of cases of infections are caused by pathogenes from gastrointestinal tract. The article presents the case of 38-year-old patient with spontaneous peritonitis who was treated surgically. The primary nature of the disease was confirmed by laparotomy and bacteriological examination results (Streptoccocus pneumonia) of ascitic fluid. After 54 days of hospitalisation and undergoing re-laparotomy, he was discharged in good condition. PMID:22166482

    Spontaneous bacterial peritonitis is a complication of ascitic patients with end-stage liver disease (ESLD); spontaneous fungal peritonitis (SFP) is a complication of ESLD less known and described. ESLD is associated to immunodepression and the resulting increased susceptibility to infections. Recent perspectives of the management of the critically ill patient with ESLD do not specify the rate of isolation of fungi in critically ill patients, not even the antifungals used for the prophylaxis, neither optimal treatment. We reviewed, in order to focus the epidemiology, characteristics, and, considering the high mortality rate of SFP, the use of optimal empirical antifungal therapy the current literature.

    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 results of treatment of 65 patients, suffering diffuse peritonitis, were analyzed. For the abdominal cavity sanation and intestinal decontamination the adopted selective bacteriophages (polyvalent pyobacteriophage, intesti-bacteriophage, and the coliproteus one) were applied. The abdominal cavity state was estimated while doing a programmed relaparotomy. Bacteriologic investigation of exudate, excreted along nasointestinal probe, and of peritoneal exudate was conducted. The intestinal motor-evacuation function restoration was estimated in accordance to data of ultrasonographic investigation. Application of the procedure proposed have promoted earlier restoration of intestinal motor and the barrier functions, and elimination of enteral insufficiency syndrome.

  15. Transepithelial chemotaxis of rat peritoneal exudate cells.

    1983-12-01

    The migration of peritoneal exudate (PE) cells into plain Millipore filters mounted in Boyden chambers occurs under random, chemokinetic and chemotactic conditions. Significant migration of such cells in vivo, however, involves both transendothelial and transepithelial penetration and occurs predominantly under pathological conditions where chemotactic agents are presumed to be present in gradient form. When Madin-Darby canine kidney (MDCK) epithelial cells are grown as a confluent monolayer on the Millipore filter of a Boyden chamber, transepithelial migration is seen only under chemotactic conditions thus modelling in vivo behaviour more effectively. The MDCK cell line exists as 2 variant strains which model different regions of the mammalian nephron. Strain I MDCK cells share features of the distal and collecting tubules and have relatively high junctional resistance (greater than 1k omega cm2). Strain II MDCK cells model the proximal segment of the nephron and have relatively low junctional resistance (c. 70 omega cm2). We have found that PE cells penetrate the less resistant strain II MDCK monolayer at a faster rate (as assessed by leading front migration) than they penetrate the tighter strain I monolayer. We have also utilized the electrophysiological features of MDCK monolayers to monitor transepithelial penetration. Our electrophysiological data indicate that rat PE cells penetrate MDCK monolayers of either strain by a transjunctional route with consequent reversible dissolution of the junctional complex. This extracellular path of PE cell migration was confirmed by ultrastructural observations. The extent of junctional dissolution and the delay in re-establishment of monolayer integrity (as assessed by electrophysiological means) are related to the concentration of PE cells added to the MDCK monolayer. Brief treatment (10 min) of the MDCK monolayer with the cation chelating agent EDTA also disrupts monolayer integrity, although its re-establishment is

    Because of increased intensity of hurricanes in the Gulf Coast region of the United States, peritoneal dialysis (PD) programs have been disrupted and patients relocated temporarily following these catastrophic events. We describe the disaster planning, implementation, and follow-up that occurred in one such PD program in New Orleans following Hurricane Katrina. Each year at the beginning of the North American hurricane season, the PD program's disaster plan is reviewed by clinic staff and copies are distributed to patients. Patients are instructed to assemble a disaster kit and are provided with contact numbers for dialysis suppliers and for a PD program in their planned evacuation city. In July 2005, this disaster plan was tested when an early tropical storm and hurricane entered the Gulf and several patients briefly relocated or evacuated because of power loss and then returned without incident. However, when Hurricane Katrina, a category 5 storm, was predicted to strike the metropolitan area, patients were notified by telephone to evacuate, and contact information, including their evacuation city and telephone and cellular phone numbers, was obtained. Patients were also reminded to take all medications, bottled water, antibacterial soap, hand sanitizer, and 4-5 days of PD supplies. Following the storm, telephone and cellular phone services were severely disrupted. However, text messaging was available to contact patients to confirm safety and to provide further instructions. Arrangements with the major dialysis suppliers to ship emergency supplies to new locations were made by the PD nurse and the patients. Only 2 of 22 patients required hospitalization because of complications resulting from evacuation failure, contamination, and inability to perform dialysis for a prolonged period of time. Both of these patients were quickly released and have continued PD. Following the event, all patients remained on PD, and most have planned to return to their home PD

  17. Bot, Cyborg and Automated Turing Test

    Science.gov (United States)

    Yan, Jeff

    The Automated Turing test (ATT) is almost a standard security technique for addressing the threat of undesirable or malicious bot programs. In this paper, we motivate an interesting adversary model, cyborgs, which are either humans assisted by bots or bots assisted by humans. Since there is always a human behind these bots, or a human can always be available on demand, ATT fails to differentiate such cyborgs from humans. The notion of “telling humans and cyborgs apart” is novel, and it can be of practical relevance in network security. Although it is a challenging task, we have had some success in telling cyborgs and humans apart automatically.

    Peritonitis remains an important complication of peritoneal dialysis and is mostly caused by aerobic enteric bacteria. Non-tuberculous mycobacteria (NTM)-associated peritonitis is an unusual but serious infection, requiring special culture techniques to avoid delay in diagnosis. We report the case of an 11-year-old girl with aplastic anemia on ambulatory peritoneal dialysis who had Mycobacterium avium complex-associated peritonitis after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This case emphasizes that we should be constantly cautious about NTM infection in allo-HSCT recipients, especially when standard cultures are negative and the infection is refractory to empirical antibiotic therapy.

    Directory of Open Access Journals (Sweden)

    Liu Jinsong

    2004-06-01

    Full Text Available Abstract Epithelial ovarian cancer (EOC is a significant cause of cancer related morbidity and mortality in women. Preferential involvement of peritoneal structures contributes to the overall poor outcome in EOC patients. Advances in biotechnology, such as cDNA microarray, are a product of the Human Genome Project and are beginning to provide fresh opportunities to understand the biology of EOC. In particular, it is now possible to examine in depth, at the molecular level, the complex relationship between the tumor itself and its surrounding microenvironment. This review focuses on the anatomy, physiology, and current immunobiologic research of peritoneal structures, and addresses certain potentially useful animal models. Changes in both the inflammatory and non-inflammatory cell compartments, as well as alterations to the extracellular matrix, appear to be signal events that contribute to the remodeling effects of the peritoneal stroma and surface epithelial cells on tumor growth and spread. These alterations may involve a number of proteins, including cytokines, chemokines, growth factors, either membrane or non-membrane bound, and integrins. Interactions between these molecules and molecular structures within the extracellular matrix, such as collagens and the proteoglycans, may contribute to a peritoneal mesothelial surface and stromal environment that is conducive to tumor cell proliferation and invasion. These alterations need to be examined and defined as possible prosnosticators and as therapeutic or diagnostic targets.

    Full Text Available Introduction. A peritoneal inclusion cyst is a very rare mesenteric cyst of mesothelial origin usually asymptomatic. A rare case of an 82-year-old white Caucasian female with a femoral hernia containing a large peritoneal inclusion cyst, mimicking strangulated hernia, is presented herein. Case Presentation. The patient was admitted to our hospital suffering from a palpable groin mass on the right, which became painful and caused great discomfort for the last hours. Physical examination revealed a tender and tense, irreducible groin mass. An inguinal operative approach was selected and the mass was found protruding through the femoral ring. After careful dissection it turned out to be a large unilocular cyst, containing serous fluid, probably originating from the peritoneum. McVay procedure was used to reapproximate the femoral ring. Histologic examination showed a peritoneal inclusion cyst. Discussion. Peritoneal inclusion cysts are usually asymptomatic but occasionally present with various, nonspecific symptoms according to their size. Our case highlights that high index of clinical suspicion and careful exploration during repair of a hernia is mandatory in order to reach the correct diagnosis about hernia’s contents.

    Questions have been raised about the safety of diagnostic hysteroscopy preceding surgical treatment of endometrial carcinoma. Several studies showed that the risk of a positive cytology among patients presenting endometrial adenocarcinoma was increased after diagnostic hysteroscopy, suggesting a peritoneal dissemination of tumor cells due to the exploration. We studied this hypothesis on the basis of a systematic review of the scientific data. Five studies fulfilling inclusion criteria have been selected and have been introduced into a fixed model of meta-analysis. On a total of 756 studied patients, 79 presented a positive peritoneal cytology. The diagnostic hysteroscopy did not increase significantly the risk of abdominal dissemination of tumor cells, the peritoneal cytology being positive among 38 patients in the group having undergone this intervention vs 41 patients in the control group (OR = 1,64; 95% CI: 0,96-2,80). In conclusion, no formal evidence is currently available concerning the role of diagnostic hysteroscopy on the frequency of peritoneal dissemination of tumor cells, or on the vital prognosis of the patients presenting with endometrial carcinoma. From the data available, there is not any reason to avoid diagnostic hysteroscopy in the initial workup of endometrial cancer. PMID:15894211

    Full Text Available Animal models for adhesion induction are heterogeneous and often poorly described. We compare and discuss different models to induce peritoneal adhesions in a randomized, experimental in vivo animal study with 72 female Wistar rats. Six different standardized techniques for peritoneal trauma were used: brushing of peritoneal sidewall and uterine horns (group 1, brushing of parietal peritoneum only (group 2, sharp excision of parietal peritoneum closed with interrupted sutures (group 3, ischemic buttons by grasping the parietal peritoneum and ligating the base with Vicryl suture (group 4, bipolar electrocoagulation of the peritoneum (group 5, and traumatisation by electrocoagulation followed by closure of the resulting peritoneal defect using Vicryl sutures (group 6. Upon second look, there were significant differences in the adhesion incidence between the groups (P<0.01. Analysis of the fraction of adhesions showed that groups 2 (0% and 5 (4% were significantly less than the other groups (P<0.01. Furthermore, group 6 (69% was significantly higher than group 1 (48% (P<0.05 and group 4 (47% (P<0.05. There was no difference between group 3 (60% and group 6 (P=0.2. From a clinical viewpoint, comparison of different electrocoagulation modes and pharmaceutical adhesion barriers is possible with standardised models.

    Kocuria species are found in the environment and on human skin. These micro-organisms are generally considered to be nonpathogenic saprophytes, rarely causing infection. However, the peritoneum has been reported to be a site of Kocuria infection. We reviewed all cases of peritonitis in peritoneal dialysis (PD) patients caused by Kocuria species that were reported in the worldwide literature. In total, 12 episodes of Kocuria species peritonitis have been reported in 9 PD patients. The median age of the patients was 62 years (range: 8 - 78 years). In the reported episodes, 4 different Kocuria species were isolated, with K. varians being the predominant species (41.7%). The most common initial symptom was abdominal pain (83.3%), followed by turbid effluent (75%) and fever (33.3%). Intraperitoneal first-generation cephalosporins and glycopeptides were the most-used antibiotics, with first-generation cephalosporins being more often preferred as first-line therapy. The median duration of treatment was 14 days, and in 2 episodes, the Tenckhoff catheter was removed. Although Kocuria peritonitis in PD patients is rare, it should be promptly treated because relapses can occur, especially with K. varians episodes.

    2002-09-01

    The peritoneal carcinomatosis is considered an unlikely treatable disease using standard procedures as surgery or systemic chemotherapy. New improvements in the knowledge of the peritoneum are inducing to consider the mesothelium of the abdominal cavity as an organ similar to the other body organs. This new consideration, unified with the understanding of conditions permitting the implant of the tumor cell into the peritoneal space previous or during the surgical manipulation of the abdominal cancers, leads to the application of news strategies as the advanced cytoreduction with every nodes reduced less than 2.5 mm followed by the chemohyperthermic peritoneal perfusion (CHPP). Last papers indicate improvements in overall survival and quality of the life in ovarian, colonic and gastric cancer treated with an extensive surgical debulking plus CHPP. These results induce surgeons and oncologists to avoid incorrect strategies in the treatment of peritoneal carcinomatosis originating from ovarian and gastrointestinal tumors. In case of malignant untreatable ascites a peritoneo-venous shunt allows a control of the ascites avoiding several hospital admissions for continuous fastidious and sometime dangerous paracentesis. A palliative surgical operation in selected patients effected by trained surgical group permits an improvement of the patient's conditions in more than 80% with a positive feed back on his or her psychological behavior.

    2010-01-01

    Peritoneal dialysis involves diffusive and convective transport and osmosis through the highly vascularized peritoneal membrane. Several lines of evidence have demonstrated that the water channel aquaporin-1 (AQP1) corresponds to the ultrasmall pore predicted by the model of peritoneal transport. Proof-of-principle studies have shown that upregulation of the expression of AQP1 in peritoneal capillaries results in increased water permeability and ultrafiltration, without affecting the osmotic gradient or small solute permeability. Conversely, studies in Aqp1 mice have shown that haplo-insufficiency for AQP1 results in significant attenuation of water transport. Recent studies have demonstrated that AQP1 is involved in the migration of different cell types, including endothelial cells. In parallel, chemical screening has identified lead compounds that could act as antagonists or agonists of AQPs, with description of putative binding sites and potential mechanisms of gating the water channel. By modulating water transport, these pharmacological agents could have clinically relevant effects in targeting specific tissues or disease states.

    Full Text Available Perforation peritonitis is the most common surgical emergency in India. Peritonitis due to upper gastrointestinal tract perforation constitutes majority of these cases. Despite advances in surgical techniques, antimicrobial therapy and intensive care support, management of peritonitis continues to be highly demanding, difficult and complex. . In contrast to western countries where lower gastro-intestinal tract perforations predominate, upper gastro intestinal tract perforations constitute the majority of cases in India1. Earlier Rawlinson in the year 1727 was the first to give a clear description of the signs and symptom of gastric ulcer and peritonitis.2 MATERIALS AND METHODS: All patients having GI perforation admitted in all surgical units of Basaweshwar Teaching and General Hospital, Gulbarga were considered for the study. A total of 50 cases were studied over a period of 18 months from Dec 2009 to May 2011.Data was entered in the proforma made for the study and analyzed RESULTS &CONCLUSION: Patient group more than 50yrs were the most commonly affected group and duodenal ulcer perforation (60% was the most common. Males (92% were affected more than females. Most common symptom was vomiting (68%. Guarding and rigidity were present in 90% patients. Laparotomy with closure of the perforation with omental patch is the commonest operative management for perforated peptic ulcer. The overall mortality was 4%

    2015-01-01

    Intraperitoneal and catheter exit site infections are the most common complications associated with prolonged peritoneal dialysis (PD) therapy used for treating the patients with end stage renal failure (ESRF). Recurrent and persistent infections often cause inflammation of the peritoneum, a condition known as infectious peritonitis and to resolve the condition, patients require antibiotic treatment. However, if the treatment is delayed or if it fails due to antibiotic resistance, the peritonitis may lead to permanent malfunctioning of peritoneal membrane causing technique failure and transferring the patients to haemodialysis. Severe and prolonged peritonitis is not only the major cause of technique failure, it is also the leading cause of mortality and morbidity in PD patients. Therefore, there is an urgent need to improve the existing PD technique so that the frequency of PD associated infections could be reduced and infectious peritonitis episodes thereof during prolonged peritoneal dialysis. In this pers...

  7. Aliskiren prevents the toxic effects of peritoneal dialysis fluids during chronic dialysis in rats.

    Directory of Open Access Journals (Sweden)

    Juan Pérez-Martínez

    Full Text Available The benefits of long-term peritoneal dialysis (PD in patients with end-stage renal failure are short-lived due to structural and functional changes in the peritoneal membrane. In this report, we provide evidence for the in vitro and in vivo participation of the renin-angiotensin-aldosterone system (RAAS in the signaling pathway leading to peritoneal fibrosis during PD. Exposure to high-glucose PD fluids (PDFs increases damage and fibrosis markers in both isolated rat peritoneal mesothelial cells and in the peritoneum of rats after chronic dialysis. In both cases, the addition of the RAAS inhibitor aliskiren markedly improved damage and fibrosis markers, and prevented functional modifications in the peritoneal transport, as measured by the peritoneal equilibrium test. These data suggest that inhibition of the RAAS may be a novel way to improve the efficacy of PD by preventing inflammation and fibrosis following peritoneal exposure to high-glucose PDFs.

  9. Transport of ions across peritoneal membrane.

    The electrical conductance of ions across the peritoneal membrane of young buffalo (approximately 18-24 months old) has been recorded. Aqueous solutions of NaF, NaNO3, NaCl, Na2SO4, KF, KNO3, KCl, K2SO4, MgCl2, CaCl2, CrCl3, MnCl2, FeCl3, CoCl2, and CuCl2 were used. The conductance values have been found to increase with increase in concentration as well as with temperature (15 to 35 degrees C) in these cases. The slope of plots of specific conductance, kappa, versus concentration exhibits a decrease in its values at relatively higher concentrations compared to those in extremely dilute solutions. Also, such slopes keep on increasing with increase in temperature. In addition, the conductance also attains a maximum limiting value at higher concentrations in the said cases. This may be attributed to a progressive accumulation of ionic species within the membrane. The kappa values of electrolytes follow the sequence for the anions: SO4(2-)>Cl->NO3->F- while that for the cations: K+>Na+>Ca2+>Mn2+>Co2+>Cu2+>Mg2+>Cr3+>Fe3+. In addition, the diffusion of ions depends upon the charge on the membrane and its porosity. The membrane porosity in relation to the size of the hydrated species diffusing through the membrane appears to determine the above sequence. As the diffusional paths in the membrane become more difficult in aqueous solutions, the mobility of large hydrated ions gets impeded by the membrane framework and the interaction with the fixed charge groups on the membrane matrix. Consequently, the membrane pores reduce the conductance of small ions, which are much hydrated. An increase in conductance with increase in temperature may be due to the state of hydration, which implies that the energy of activation for the ionic transport across the membrane follows the sequence of crystallographic radii of ions accordingly. The Eyring's equation, kappa=(RT/Nh)exp[-DeltaH*/RT]exp[DeltaS*/R], has been found suitable for explaining the temperature dependence of conductance in

    This new session at QNDE reflects the growing interest in inspection automation. Our paper describes a newly developed platform that makes the complex NDE automation possible without the need for software programmers. Inspection tasks that are tedious, error-prone or impossible for humans to perform can now be automated using a form of drag and drop visual scripting. Our work attempts to rectify the problem that NDE is not keeping pace with the rest of factory automation. Outside of NDE, robots routinely and autonomously machine parts, assemble components, weld structures and report progress to corporate databases. By contrast, components arriving in the NDT department typically require manual part handling, calibrations and analysis. The automation examples in this paper cover the development of robotic thickness gauging and the use of adaptive contour following on the NRU reactor inspection at Chalk River.

    Alexandra Dos Anjos Cassado

    2015-05-01

    Full Text Available Tissue macrophages play a crucial role in the maintenance of tissue homeostasis and also contribute to inflammatory and reparatory responses during pathogenic infection and tissue injury. The high heterogeneity of these macrophages is consistent with their adaptation to distinct tissue environments and specialization to develop niche-specific functions. Although peritoneal macrophages are one of best-studied macrophage populations, only recently it was demonstrated the co-existence of two subsets in mouse PerC, which exhibit distinct phenotypes, functions and origins. These macrophage subsets have been classified according to their morphology as LPMs (large peritoneal macrophages and SPMs (small peritoneal macrophages. LPMs, the most abundant subset under steady-state conditions, express high levels of F4/80 and low levels of class II molecules of the major histocompatibility complex (MHC. LPMs appear to be originated from embriogenic precursors, and their maintenance in PerC is regulated by expression of specific transcription factors and tissue-derived signals. Conversely, SPMs, a minor subset in unstimulated PerC, have a F4/80lowMHC-IIhigh phenotype and are generated from bone-marrow-derived myeloid precursors. In response to infectious or inflammatory stimuli, the cellular composition of PerC is dramatically altered, where LPMs disappear and SPMs become the prevalent population together with their precursor, the inflammatory monocyte. SPMs appear to be the major source of inflammatory mediators in PerC during infection whereas LPMs contribute for gut-associated lymphoid tissue (GALT-independent and retinoic acid-dependent IgA production by peritoneal B-1 cells. In the last years, considerable efforts have been made to broaden our understanding of LPM and SPM origin, transcriptional regulation and functional profile. This review addresses these issues, focusing on the impact of tissue-derived signals and external stimulation in the complex

    Peritoneal lavage was given during four days to rats subjected either to transection and re-anastomosis or perforation of the descending part of the colon or caecum. Control rats were treated in the smae way but did not receive peritoneal lavage. The rats which were treated with a colonic anastomosis and peritoneal lavage had significantly less abdominal adhesions, peritonitis and peritoneal fluid observed at autopsy 11 or 60 days after surgery. No rats developed anastomosis insufficiency and all survived. Peritoneal lavage in rats subjected to colonic or caecal perforation increased the survival time and reduced the mortality rate, the frequency of adhesions and the signs of peritonitis. An increased frequency of peritoneal adhesions was observed after extensive mobilization of the colon during operation when no peritoneal lavage had been given. The peritoneal lavage catheter per se did not cause adhesions.

    Expert systems have considerable potential to assist computer users in managing the large volume of information available to them. One possible use of an expert system is to model the information retrieval interests of a human user and then make recommendations to the user as to articles of interest. At Cal Poly, a prototype expert system written in the C Language Integrated Production System (CLIPS) serves as an Automated Information Retrieval System (AIRS). AIRS monitors a user's reading preferences, develops a profile of the user, and then evaluates items returned from the information base. When prompted by the user, AIRS returns a list of items of interest to the user. In order to minimize the impact on system resources, AIRS is designed to run in the background during periods of light system use.

Here, we report a case of tunnel infection in which imaging with positron-emission tomography (PET) correctly predicted failure of conservative management. A 61-year-old man with diabetic nephropathy commenced PD in January 2008. He developed erythema and drainage at the exit site, with negative cultures in February 2008, and frank exit-site infection (ESI) with purulent drainage growing methicillin-sensitive Staphylococcus aureus [MSSA (treated with 3 weeks of oral dicloxacillin)] in August 2008. Subsequently, MSSA-growing purulent drainage from the exit site persisted. Systemic antibiotics were not administered, but there was gradual improvement with gentamicin ointment alone. In November 2008, the patient developed partial extrusion of the outer cuff of the PD catheter. In January 2009, a new ESI developed. Despite a week of treatment with cefazolin and gentamicin, the patient still developed his first episode of peritonitis with coagulase-negative Staphylococcus. He then received intraperitoneal vancomycin with good response. Although the ESI appeared to have responded to the treatment, PET imaging showed increased fludeoxyglucose (FDG) activity in the whole abdominal wall portion of the PD catheter. The patient resisted removal of the catheter and had no further signs of infection until June 2009. At that time he presented with exuberant inflammatory tissue ("proud flesh") at the exit site. Repeated PET imaging again showed increased FDG activity along the abdominal wall portion of the catheter. The PD catheter was removed and found to be infected. The patient was placed on temporary hemodialysis. This case demonstrates that PET imaging, in addition to other imaging techniques, may be useful for diagnosing and managing PD catheter infections.

    Polymorphonuclear (PMN) cell count in the ascitic fluid is essential for the diagnosis and management of spontaneous bacterial peritonitis (SBP). To date, PMN cell count is routinely performed by traditional manual counting. However, this method is time-consuming, costly, and not always timely available. Therefore, considerable efforts have been made in recent years to develop an alternative test for a more rapid diagnosis and monitoring of SBP. The use of urinary reagent strips was proposed to achieve an "instant" bedside diagnosis of SBP. A series of reports evaluated the urine strip test for SBP diagnosis and reported promising results. However, a recent large multicenter study revealed a surprising lack of diagnostic efficacy of the urine screening test for SBP diagnosis. Another method, more recently proposed as an alternative to the manual PMN count, is the measurement of lactoferrin in ascitic fluid, but the data available on the diagnostic value of this test are limited to a single study. However,both urinary reagent strips and ascitic lactoferrin tests are qualitative methods and need, therefore, to be further confirmed by standard cytology of the ascitic fluid.To date, the only quantitative method proposed as a valid alternative to manual PMN counting is automated blood cell counters, commonly used in all laboratories for blood cell counting. Data available in the literature on the diagnostic performance of this method are limited but very promising, and this tool seems to have the potential to replace the manual counting method.

    Ascites remain the commonest complication of decom-pensated cirrhosis. Spontaneous bacterial peritonitis (SBP) is defined as the infection of ascitic fluid (AF) in the ab-sence of a contiguous source of infection and/or an intra-abdominal inflammatory focus. An AF polymorphonuclear (PMN) leucocyte count ≥ 250/mm3 -irrespective of the AF culture result- is universally accepted nowadays as the best surrogate marker for diagnosing SBP. Frequently the results of the manual or automated PMN count do not reach the hands of the responsible medical personnel in a timely manner. However, this is a crucial step in SBP man-agement. Since 2000, 26 studies (most of them published as full papers) have checked the validity of using leukocyte esterase reagent strips (LERS) in SBP diagnosis. LERS appear to have low sensitivity for SBP, some LERS types more than others. On the other hand, though, LERS have consistently given a high negative predictive value (> 95% in the majority of the studies) and this supports the use of LERS as a preliminary screening tool for SBP diagnosis. Finally, an AF-tailored dipstick has been developed. Within the proper setting, it is set to become the mainstream pro-cess for handling AF samples.

  4. The frequency of peritoneal tuberculosis using diagnostic laparoscopy in clinically suspected cases

    International Nuclear Information System (INIS)

    Introduction: Diagnostic laparoscopy allows the visual examination and documentation of intra-abdominal organs in order to detect any pathology. It is an important tool for final minimally invasive exploration of patients with abdominal tuberculosis, the diagnosis of which remains uncertain despite employing the requisite laboratory and non-invasive imaging investigations. Objective: To determine the frequency of peritoneal tuberculosis using diagnostic laparoscopy in clinically suspected cases of peritoneal tuberculosis. Study Design: Cross sectional survey. Setting: The study was conducted in all the four Surgical Wards on surgical floor of Mayo Hospital Lahore. Duration of Study with Dates: Six months (1st July 2009 to 31st December 2009). Material and Methods: 35 Patients aged between 13-60 years with clinical suspicion of peritoneal tuberculosis were selected. The patients underwent the procedure accordingly. Per operative diagnosis of peritoneal tuberculosis made on the basis of presence of any or all of the operative (laparoscopic) findings such as multiple peritoneal adhesions, fibrous bands, whitish peritoneal tubercles, omental thickening and ascites. Diagnosis was confirmed with histopathology of peritoneal tissue biopsy. Also the biochemical analysis and culture sensitivity of ascetic fluid was routinely performed if any ascites is present. Results: Out of 35 patients, 40% were males and 60% females with mean age of 24.91+-6.69 years. The Laparoscopic findings of peritoneal tuberculosis were whitish peritoneal tubercles (57.2%) peritoneal adhesions (28.6%), ascites (17.2%), omental thickening (14.3%), fibrous bands (11.4%) and swollen edematous appendix (5.7%). Eighty percent were labeled with diagnosis of peritoneal tuberculosis on basis of diagnostic laparoscopy. These patients were confirmed to have peritoneal tuberculosis on histopathology of tissue biopsy. Conclusion: Diagnostic laparoscopy is useful in patients with suspected peritoneal

    Vongbunyong, Supachai

    2015-01-01

    This book presents a number of aspects to be considered in the development of disassembly automation, including the mechanical system, vision system and intelligent planner. The implementation of cognitive robotics increases the flexibility and degree of autonomy of the disassembly system. Disassembly, as a step in the treatment of end-of-life products, can allow the recovery of embodied value left within disposed products, as well as the appropriate separation of potentially-hazardous components. In the end-of-life treatment industry, disassembly has largely been limited to manual labor, which is expensive in developed countries. Automation is one possible solution for economic feasibility. The target audience primarily comprises researchers and experts in the field, but the book may also be beneficial for graduate students.

    2009-01-01

    This presentation describes work to integrate a set of tools to support early model-based analysis of failures and hazards due to system-software interactions. The tools perform and assist analysts in the following tasks: 1) extract model parts from text for architecture and safety/hazard models; 2) combine the parts with library information to develop the models for visualization and analysis; 3) perform graph analysis and simulation to identify and evaluate possible paths from hazard sources to vulnerable entities and functions, in nominal and anomalous system-software configurations and scenarios; and 4) identify resulting candidate scenarios for software integration testing. There has been significant technical progress in model extraction from Orion program text sources, architecture model derivation (components and connections) and documentation of extraction sources. Models have been derived from Internal Interface Requirements Documents (IIRDs) and FMEA documents. Linguistic text processing is used to extract model parts and relationships, and the Aerospace Ontology also aids automated model development from the extracted information. Visualizations of these models assist analysts in requirements overview and in checking consistency and completeness.

    Sir William Turner (1832-1916) was Professor of Anatomy at the University of Edinburgh. His classic paper of 1863 on the anastomoses between the parietal and visceral branches of the abdominal aorta, later known as the sub-peritoneal arterial plexus of Turner, has mostly been forgotten. Located in the retroperitoneum and surrounding the kidneys and other adjacent structures, this plexus is an important route of collateral circulation. In the current paper, we discuss the sub-peritoneal arterial plexus as described by Turner in 1863 and review the literature concerning its potential clinical significance in the kidney, emphasizing its probable role in the metastatic spread of various tumors of abdominal organs and in the continuing viability of the kidney after renal artery occlusion. A biographical sketch of Sir William Turner is also presented.

    The mechanisms of transperitoneal sodium transport during hypertonic peritoneal dialysis were evaluated by kinetic modelling. A total of six nested mathematical models were designed to elucidate the presence or absence of diffusive, non-lymphatic convective and lymphatic convective solute transport....... Experimental results were obtained from 26 non-diabetic patients undergoing peritoneal dialysis. The model validation procedure demonstrated that only diffusive and non-lymphatic convective transport mechanisms were identifiable in the transperitoneal transport of sodium. Non-lymphatic convective sodium...... transport was the most important quantitative transport mechanism during the first 90 min of the dwell. Significant sodium sieving was demonstrated and explains the observation of hypernatremia in dialysis with hypertonic dialysis fluid....

    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. PMID:27659930

    1983-05-01

    Ultrasonic images are analyzed in 14 patients aged 5 to 60 years with peritoneal tuberculosis. Images frequently demonstrated an anterior subparietal zone of transonance of variable thickness, associated with masses exhibiting transonance and multiple frequency outlines englobing digestive echos with intra-abdominal enlarged glands and free or partitioned ascites. Less frequently observed images were those of digestive tube loops adherent to the wall, hepatic or splenic lesions. Correlations were sought between these ultrasonic signs and results of endoscopy. Diagnosis of peritoneal tuberculosis is emphasized as being based mainly on histology and bacteriology, but ultrasonography conducted initially can reduce the time for diagnosis, suggest the diagnosis, assess any extension of the disease, and evaluate effects of treatment.

    The ideal contrast agent in patients suspected of having gastrointestinal perforation is an iso-osmolar, or nearly iso-osmolar substance, that causes no peritoneal reaction. Iopamidol is a nonionic water-soluble contrast medium that may be considered in such situations. Intraperitoneal injections of ionic and nonionic contrast agents were compared in rats to study potentially harmful peritoneal inflammation. Only intraperitoneal barium injection produced any significant tissue reaction, such as adhesions and ascites. There was no difference between iopamidol and the other water-soluble contrast agents. Iopamidol may satisfy the need for nonreactive and nearly iso-osmolar contrast agents for evaluating patients with possible bowel perforation. However, the high cost of this agent may make its clinical application impractical.

  6. Peritoneal and mediastinal highly differentiated follicular carcinoma of ovarian origin

    International Nuclear Information System (INIS)

    A 70-year-old female patient presented to her primary care doctor with persistent elevated alkaline phosphatase of suspected metastatic etiology. Computed tomography demonstrated epicardial and peritoneal nodules. Biopsy of one of the peritoneal nodules revealed thyroid tissue and extraovarian struma ovarii was considered. The patient had a history of remote total abdominal hysterectomy and bilateral salpingo-oophorectomy 31 years prior for endometriosis with no available pathology from that surgery. The patient recalls being told that she had a left ovarian cyst. A thyroid ultrasound was performed that demonstrated multiple nodules without concerning features; however, due to high clinical suspicion, a total thyroidectomy was performed. Upon full histological evaluation a 0.5 cm papillary microcarcinoma was found. Given the rarity of metastatic papillary cancer to the peritoneum and the small size and grade of the tumor, a diagnosis of highly differentiated follicular carcinoma of ovarian origin was favored. The patient was subsequently treated with radioiodine therapy

    Full Text Available Enteric protozoan infections are a well-documented cause of diarrhea in immunocompromised patients. Special stains on stool specimens are routinely performed in such patients to diagnose these protozoa namely cryptosporidium, microsporidium, and isospora. Duodenal and jejunal biopsies can also be performed to obtain a tissue diagnosis. We report a case of microsporidium enteritis diagnosed on histopathological examination of small bowel resection specimen in a case of perforation peritonitis. The patient was a known HIV-positive on antiretroviral treatment for 2 years and on antitubercular treatment for 3 months. This case report highlights the importance of carefully screening the resection specimens for protozoal infections in immunocompromised individuals. The association of perforation peritonitis and microsporidium is rare. Hence, the possibility that untreated microsporidium infection can lead to perforation cannot be ruled out.

    Peritoneal metastasis (PM) has traditionally been approached with therapeutic nihilism. The evolution of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) over the last two decades, however, has caused a paradigm shift in treatment for PM. This modality is rapidly gaining acceptance as standard of care for PM from various cancers. This article reviews the current literature regarding the use of CRS/HIPEC for PM from the most common intra-abdominal malignancies. PMID:25164477

    Genetic factors are presumed to influence the incidence of feline infectious peritonitis (FIP), especially among pedigreed cats. However, proof for the existence of such factors has been limited and mainly anecdotal. Therefore, we sought evidence for genetic susceptibility to FIP using feline high density single nucleotide polymorphism (SNP) arrays in a genome-wide association study (GWAS). Birman cats were chosen for GWAS because they are highly inbred and suffer a high incidence of FIP. DNA...

    Burkitt lymphoma presenting as a peritoneal and small thickening problem mimicking carcinomatosis is very rare. We present a previously healthy 7-year-old boy with a 1-week history of worsening abdominal distention, vomiting and melena. He demonstrated liver nodules, but no pathologic chest or abdominal adenopathy was present. It was finally determined that he was suffering from Burkitt lymphoma. We present this case because it is such a rare but very significant manifestation of Burkitt lymphoma. (orig.)

    Full Text Available Background: Peritonitis, while no longer the over whelming problem it once was, is still the most common cause of death, ballooned surgical treatment of abdominal disease. In 5 to 7 present of all autopsies, peritonitis is either the primary or a contributory cause of death. Therefore the present study has been undertaken to find out the actual cause of death peritonitis. Methods: This study was conducted after the institutional ethical clearance and informed written consent from all the subjects. Fifty surgically proved perforative peritonitis cases admitted to the surgical wards were included in the study. Radiological examination was done in all the cases to detect pneumoperitoneum. Ulcer edge biopsy was taken from peptic and non-specific ileal perforations. The data are expressed as mean and the percentile was calculated in each parameters. Results: 90% of the subjects were males and the patients belong to the age group of 31-40 years. Of the 32 cases of perforated peptic ulcer, 19 gave the previous history of pain abdomen lasting from 6 months to 15 years, one gave the history of fever and in 14 cases there was no history. The pneumoperitoneum is demonstrable on X-ray in 60-80% cases of peptic as well as non-traumatic small bowel perforations. Conclusion: The study showed that the maximum mortality occurred in those patients who were admitted to the hospital after more than 24 hours from the time of appearance of the first symptom. Therefore, it is advised not to delay in attending the hospital rather than delayed surgery. [Int J Res Med Sci 2014; 2(3.000: 916-919

  18. Effectiveness of Home Visits to Pediatric Peritoneal Dialysis Patients

    Home visits by trained personnel to patients undergoing home dialysis are required, but little is reported about the effectiveness of such home visits. We retrospectively reviewed home visits to 22 pediatric patients undergoing continuous cycling peritoneal dialysis (PD) at home. A trained dialysis nurse completed each home visit. An average of 1.5 pertinent dialysis findings and 1 pertinent medication finding was noted for each home visit to these patients. The interdisciplinary dialysis tea...

    Ultrafiltration (UF) failure is one of the most important causes of long-term peritoneal dialysis (PD) failure in patients. Osmotic forces acting across small and ultra-small pores generate a UF with solutes through the small pore and free water transport (FWT) through the ultra-small pore. The ability of glucose to exert an osmotic pressure sufficient to cause UF is the so-called 'osmotic conductance to glucose' (OCG) of the peritoneal membrane. Our study proposes a simple method to determine both the OCG and FWT. In 50 patients on PD, a Double Mini-Peritoneal Equilibration Test (Double Mini-PET), consisting of two Mini-PET, was performed consecutively. A solution of 1.36% glucose was used for the first test, whereas a solution of 3.86% glucose was used for the second test. The sodium removal values and the differences in UF between the two tests were used to calculate FWT and the OCG. Patients with UF failure showed significant reductions not only in the OCG and the FWT but also of UF of small pores. The Double Mini-PET is simple, fast, and could become useful to evaluate patients on PD in everyday clinical practice. PMID:17609692

  20. Pleuroperitoneal leak complicating peritoneal dialysis: a case series.

    LENUS (Irish Health Repository)

    2012-02-01

    Pressure related complications such as abdominal wall hernias occur with relative frequency in patients on peritoneal dialysis. Less frequently, a transudative pleural effusion containing dialysate can develop. This phenomenon appears to be due to increased intra-abdominal pressure in the setting of congenital or acquired diaphragmatic defects. We report three cases of pleuroperitoneal leak that occurred within a nine-month period at our institution. We review the literature on this topic, and discuss management options. The pleural effusion resolved in one patient following drainage of the peritoneum and a switch to haemodialysis. One patient required emergency thoracocentesis. The third patient developed a complex effusion requiring surgical intervention. The three cases highlight the variability of this condition in terms of timing, symptoms and management. The diagnosis of a pleuroperitoneal leak is an important one as it is managed very differently to most transudative pleural effusions seen in this patient population. Surgical repair may be necessary in those patients who wish to resume peritoneal dialysis, or in those patients with complex effusions. Pleuroperitoneal leak should be considered in the differential diagnosis of a pleural effusion, particularly a right-sided effusion, in a patient on peritoneal dialysis.

    Full Text Available The International Society for Peritoneal Dialysis recommends the regular application of topical antibiotic-containing preparations in addition to a routine exit site care to reduce the risk of exit site infection (ESI. Among these prophylactic antimicrobial preparations, topical gentamicin is one of the widely used and effective antibiotics for prevention of ESI and peritonitis in peritoneal dialysis (PD patients. Overall, topical gentamicin is well tolerated; however, its use can be associated with the development of allergic contact dermatitis (ACD. We describe a first reported case of PD catheter exit site contact ACD due to topical gentamicin mimicking ESI. The patient in this report developed worsening violaceous in color and pruritic rash surrounding the PD catheter exit site that appeared 3 weeks after the initiation of gentamicin cream. The association between development of rash and initiation of topical gentamicin led to a suspicion of local reaction to gentamicin rather than ESI. Skin biopsy confirmed ACD. Discontinuation of the provoking agent and subsequent treatment with topical hydrocortisone application led to a resolution of the exit site rash. Any rash at a PD catheter exit site should be considered infectious until proven otherwise. However, it is important to be aware of noninfectious etiologies of exit site rashes as the treatment of these 2 conditions differs.

    Atrial natriuretic peptide (ANP) is an important component of the natriuretic peptide system. A great role in many regulatory systems is played by mast cells. Meanwhile involvement of these cells in ANP activity is poorly studied. In this work, we have shown the presence of ANP in rat peritoneal mast cells. Pure fraction of mast cells was obtained by separation of rat peritoneal cells on a Percoll density gradient. By Western blotting, two ANP-immunoreactive proteins of molecular masses of 2.5 kDa and 16.9 kDa were detected in lysates from these mast cells. Electron microscope immunogold labeling has revealed the presence of ANP-immunoreactive material in storage, secreting and released granules of mast cells. Our findings indicate the rat peritoneal mast cells to contain both ANP prohormone and ANP. These both peptides are located in mast cell secretory granules and released by mechanism of degranulation. It is discussed that many mast cell functions might be due to production of natriuretic peptides by these cells.

    Full Text Available Abstract Introduction Situs inversus is a congenital anomaly characterized by the transposition of the abdominal viscera. When associated with dextrocardia, it is known as situs inversus totalis. This condition is rare and can be a diagnostic problem when associated with appendicular peritonitis. Case presentation We report the case of a 20-year-old African man who presented to the emergency department with a 4-day history of diffuse abdominal pain, which began in his left iliac region and hypogastrium. After examination, we initiated a surgical exploration for peritonitis. We discovered a situs inversus at the left side of his liver, and his appendix was perforated in its middle third. A complementary post-operative thoracic and abdominal tomodensitometry revealed a situs inversus totalis. Conclusion Appendicular peritonitis in situs inversus is a rare association that can present a diagnostic problem. Morphologic exploration methods such as ultrasonography, tomodensitometry, magnetic resonance imaging, and laparoscopy may contribute to the early management of the disease and give guidance in choosing the most appropriate treatment for patients.

    This paper addresses the important intelligent predicting problem of peritoneal absorption rate in the peritoneal dialysis treament process of renal failure. As the index of dialysis adequacy, KT/V and Ccr are widely used and accepted. However,growing evidence suggests that the fluid balance may play a critical role in dialysis adequacy and patient outcome. Peritoneal fluid absorption decreases the peritoneal fluid removal. Understanding the peritoneal fluid absorption rate will help clinicians to opthnize the dialysis dwell time. The neural network approach is applied to the prediction of peritoneal absorption rate. Compared with multivariable regression method, the experimental results showed that neural network method has an advantage over multivariable regression. The application of this predicting method based-on neural network in clinic is instructive.

    Candida species have been implicated as significant contributors to morbidity in the neonatal period and are associated with 25-50% of mortality in invasive neonatal candidiasis. Peritoneal candidiasis, being paucisymptomatic, cannot often be correctly identified in a preterm neonate. The correct approach to diagnosis of neonatal peritoneal candidiasis is taking into account the epidemiology along with a strong clinical suspicion and appropriate timely diagnostic interventions. We report a case of fatal neonatal peritoneal candidiasis which was misdiagnosed as mucormycosis.

    Objective Hypomagnesemia has been associated with an increase in mortality among the general population as well as patients with chronic kidney disease or those on hemodialysis. However, this association has not been thoroughly studied in patients undergoing peritoneal dialysis. The aim of this study was to evaluate the association between serum magnesium concentrations and all-cause and cardiovascular mortalities in peritoneal dialysis patients. Methods This single-center retrospective study included 253 incident peritoneal dialysis patients enrolled between July 1, 2005 and December 31, 2014 and followed to June 30, 2015. Patient’s demographic characteristics as well as clinical and laboratory measurements were collected. Results Of 253 patients evaluated, 36 patients (14.2%) suffered from hypomagnesemia. During a median follow-up of 29 months (range: 4–120 months), 60 patients (23.7%) died, and 35 (58.3%) of these deaths were attributed to cardiovascular causes. Low serum magnesium was positively associated with peritoneal dialysis duration (r = 0.303, p < 0.001) as well as serum concentrations of albumin (r = 0.220, p < 0.001), triglycerides (r = 0.160, p = 0.011), potassium (r = 0.156, p = 0.013), calcium(r = 0.299, p < 0.001)and phosphate (r = 0.191, p = 0.002). Patients in the hypomagnesemia group had a lower survival rate than those in the normal magnesium groups (p < 0.001). In a multivariate Cox proportional hazards regression analysis, serum magnesium was an independent negative predictor of all-cause mortality (hazard ratio [HR] = 0.075, p = 0.011) and cardiovascular mortality (HR = 0.003, p < 0.001), especially in female patients. However, in univariate and multivariate Cox analysis, △Mg(difference between 1-year magnesium and baseline magnesium) was not an independent predictor of all-cause mortality and cardiovascular mortality. Conclusion Hypomagnesemia was common among peritoneal dialysis patients and was independently associated with all

    Full Text Available Rothia dentocariosa is a commensal organism of the human oropharynx. Clinical infection due to this organism is rare. A case of recurrent peritoneal dialysis-related peritonitis caused by R dentocariosa and a review of the literature is reported. Isolation of R dentocariosa from dialysate fluid should not be dismissed as a contaminant. Although there are no interpretive criteria for antimicrobial susceptibility testing, R dentocariosa appears to be susceptible to a variety of antibiotics including beta-lactams, vancomycin and aminoglycosides. Optimal therapy of peritoneal dialysis peritonitis caused by this organism may also require removal of the catheter.

    The advent of automation in materials testing has been in large part responsible for recent radical changes in the materials testing field: Tests virtually impossible to perform without a computer have become more straightforward to conduct. In addition, standardized tests may be performed with enhanced efficiency and repeatability. A typical automated system is described in terms of its primary subsystems — an analog station, a digital computer, and a processor interface. The processor interface links the analog functions with the digital computer; it includes data acquisition, command function generation, and test control functions. Features of automated testing are described with emphasis on calculated variable control, control of a variable that is computed by the processor and cannot be read directly from a transducer. Three calculated variable tests are described: a yield surface probe test, a thermomechanical fatigue test, and a constant-stress-intensity range crack-growth test. Future developments are discussed.

    Background Peritoneal dissemination is the most common pattern of metastasis in advanced gastric carcinoma with serosal invasion. In the present study, we reported the clinical relevance of a new diagnostic method involving RT-PCR, using survivin as the target gene, for the detection of free cancer cells in peritoneal washes.Methods Intraoperative peritoneal washes were obtained from 48 patients who underwent surgery for gastric cancer. RT-PCR analysis with primers specific for survivin and conventional cytological examinations were both performed.Results Survivin mRNA was not detected in any peritoneal wash samples from patients with benign disease, but was detected in 28 of 48 samples taken from patients with gastric cancer and in all metastastic nodules. Survivin expression in the peritoneal cavity significantly correlated with depth of cancer invasion, lymph node metastasis, and TNM stage. There were 92% of clinically evident peritoneal metastasis cases showed detectable survivin expression. The combination of survivin RT-PCR and cytological examination yielded positive results in 66.7% (32/48) of patients with gastric cancer, much higher than the results produced by cytological method alone. Conclusions Survivin mRNA detected in peritoneal lavage fluid might indicate the presence of free cancer cells in the peritoneal cavity. The high sensitivity of the RT-PCR-based survivin assay suggests that survivin serves as a molecular marker for detecting peritoneal micrometastasis. Its ubiquitous expression in peritoneal cancer cells and metastatic nodules also suggests a promising future therapeutic strategy based on survivin inhibition for cases of gastric cancer involving peritoneal metastasis.

    Full Text Available Abstract Introduction Peritonitis is a life-threatening condition with a multitude of etiologies that can vary with geographic location. The aims of this study were to elucidate the etiology, clinical presentation and outcomes associated with peritonitis in Lilongwe, Malawi. Methods All patients admitted to Kamuzu Central Hospital (KCH who underwent an operation for treatment of peritonitis during the calendar year 2008 were eligible. Peritonitis was defined as abdominal rigidity, rebound tenderness, and/or guarding in one or more abdominal quadrants. Subjects were identified from a review of the medical records for all patients admitted to the adult general surgical ward and the operative log book. Those who met the definition of peritonitis and underwent celiotomy were included. Results 190 subjects were identified. The most common etiologies were appendicitis (22%, intestinal volvulus (17%, perforated peptic ulcer (11% and small bowel perforation (11%. The overall mortality rate associated with peritonitis was 15%, with the highest mortality rates observed in solid organ rupture (35%, perforated peptic ulcer (33%, primary/idiopathic peritonitis (27%, tubo-ovarian abscess (20% and small bowel perforation (15%. Factors associated with death included abdominal rigidity, generalized (versus localized peritonitis, hypotension, tachycardia and anemia (p Conclusions There are several signs and laboratory findings predictive of poor outcome in Malawian patients with peritonitis. Tachycardia, hypotension, anemia, abdominal rigidity and generalized peritonitis are the most predictive of death (P nd most common cause of peritonitis in Malawi and gallbladder disease, common in Ethiopia but not observed in Malawi. Future research should investigate whether correction of factors associated with mortality might improve outcomes.

    We present the automation mechanisms that have been added to the Data Acquisition and Run Control systems of the Compact Muon Solenoid (CMS) experiment during Run 1 of the LHC, ranging from the automation of routine tasks to automatic error recovery and context-sensitive guidance to the operator. These mechanisms helped CMS to maintain a data taking efficiency above 90% and to even improve it to 95% towards the end of Run 1, despite an increase in the occurrence of single-event upsets in sub-detector electronics at high LHC luminosity.

    International Nuclear Information System (INIS)

    This paper describes an automated phantom assay system developed for assaying phantoms spiked with minute quantities of radionuclides. The system includes a computer-controlled linear-translation table that positions the phantom at exact distances from a spectrometer. A multichannel analyzer (MCA) interfaces with a computer to collect gamma spectral data. Signals transmitted between the controller and MCA synchronize data collection and phantom positioning. Measured data are then stored on disk for subsequent analysis. The automated system allows continuous unattended operation and ensures reproducible results

    An apparatus and process for the continuous, near real-time monitoring of low-level concentrations of organic compounds in a liquid, and, more particularly, a water stream. A small liquid volume of flow from a liquid process stream containing organic compounds is diverted by an automated process to a heated vaporization capillary where the liquid volume is vaporized to a gas that flows to an automated gas chromatograph separation column to chromatographically separate the organic compounds. Organic compounds are detected and the information transmitted to a control system for use in process control. Concentrations of organic compounds less than one part per million are detected in less than one minute.

    Objective: The objective of this study was to compare the underestimation rate of invasive carcinoma caseswith ductal carcinoma in situ (DCIS) at percutaneous ultrasound-guided core biopsies of breast lesions between 14-gaugeautomated core needle biopsy (ACNB) and 11-gauge vacuum-assisted biopsy (VAB), and analyze the diagnostic advantagesand insufficiencies in DCIS between this two methods, and to determine the relationship between the lesion type (masses ormicrocalcifications on radiological findings ) and DCIS underestimation rate. Methods: We collected 152 breast lesions whichwere diagnosed as DCIS by retrospectively reviewing data about ultrasound-guided biopsies of breast lesions (from February2003 to July 2010). There were 98 lesions in 95 patients by 14-gauge ACNB, and 54 lesions in 52 patients by 11-gauge VAB(The system used in this study called Mammatome, MMT). The clinical and radiological findings were reviewed; meanwhileall the selected patients had histological results of the biopsies and follow-up surgeries which also achieved the reliablepathological results to compare with the biopsy results. The differences between two correlated histological results defined asunderestimation, and the histological DCIS underestimation rates were compared between the two groups. According to theradiological characteristics, each group was classified into two subgroups (masses or microcalcifications group), and the differencesbetween subgroups were also analyzed. Results: The DCIS underestimation rate was 45.9% (45/98) for 14-gaugeACNB and 16.6% (9/54) for MMT. According to the lesion type on ultrasonography, DCIS underestimation was 31.0% (26/84)in masses (43.1% using ACNB and 12.1% using MMT; P = 0.003) and 42.6% (29/68) in microcalcifications (48.9% usingACNB and 23.8% using MMT; P = 0.036). Conclusion: The underestimation rate of invasive carcinoma in cases with DCISat ultrasound-guided core biopsies is significantly higher for ACNB than for MMT. Furthermore

    Full Text Available Sixteen adult horses were randomly divided into four equal groups of four animals and each group was injected intraperitoneally with one of the following suspension: Group I, 100×10(7 colony-forming units (CFU of E. coli diluted in 500ml of 0.9% saline; Group II, 100×10(7 CFU of Bacteroides fragilis in 500ml of 0.9% saline; Group III, 100×10(7 CFU of E. coli in combination with 100×10(7 CFU of B. fragilis in 500ml of 0.9% saline; Group IV, 500ml of 0.9% saline. A significant increase in leukocyte number was observed in the peritoneal fluid by four hours after the inoculations in animals of Group I and II, and by eight hours in animals of Group III. The highest cell count observed was 516×10³ leukocytes/mm³. Significant increases in peritoneal fluid fibrinogen (1g/dl and total protein (9.1% concentrations were also observed. Horses inoculated with pure cultures of either E. coli or B. fragilis demonstrated mild and self-limiting peritonitis, while those inoculated with a combination of both bacteria demonstrated laboratory findings of higher intensity and duration.Dezesseis eqüinos adultos foram aleatoriamente divididos em quatro grupos de quatro animais que receberam inoculação intraperitoneal das seguintes suspenções: grupo I, 100×10(7 unidades formadoras de colônias (CFU de E. coli diluídas em 500ml de solução salina a 0,9%; grupo II, 100×10(7 CFU de Bacteroides fragilis em 500ml de solução salina a 0,9%; grupo III, 100×10(7 CFU de E. coli combinados com 100×10(7 CFU de B. fragilis em 500ml de solução salina a 0,9%; grupo IV, 500ml de solução salina a 0,9%. Observou-se aumento significativo do número de leucócitos no líquido peritoneal quatro horas após as inoculações dos animais dos grupos I e II, e oito horas após as inoculações dos animais do grupo III. A contagem mais elevada foi de 516×10³ leucócitos/mm³. Aumentos significativos nas concentrações de fibrinogênio (1g/dl e proteína total (9

    We studied the in vitro ability of lectin-treated murine peritoneal macrophages to attach and phagocytize particulate antigens. Glucose and mannose specific lectins such as Con-A and lentil lectin, as well as complex lactosamine residues specific lectins, such as Phaseolus vulgaris var. cacahuate and Phaseolus coccineus var. alubia, increased the macrophage phagocytic activity towards heterologous erythrocytes, whereas peanut agglutinin, a galactose-specific lectin, diminished the macrophage phagocytic activity. These results suggest that a galactose-N-acetyl-D galactosamine-containing structure could participate as negative modulator of the phagocytic activity. PMID:7851961

    Peritoneal adhesions are a near inevitable occurrence after laparotomy and a major cause of both patient and physician misery. To date, clinical attempts at their amelioration have concentrated on manipulating the physical factors that affect their development despite a wealth of experimental data elucidating the molecular mechanisms that underlie their initiation, development and maturation. However, the advent of targeted, specific anti-cytokine agents as directed therapy for inflammatory and neoplastic conditions raises the prospect of a new era for anti-adhesion strategies. To harness this potential will require considerable cross-disciplinary collaboration and that surgeon-scientists propel themselves to the forefront of this emerging field.

    The case reported here concerns an alcoholic pork-butcher who presented with severe colitis with peritonitis, caused by the only ciliate protozoan capable of infecting humans, Balantidium coli. This parasite is common in a variety of domestic and wild mammals, mainly pigs; however, its prevalence rate in humans is very low--particularly in industrialised, northern countries, including France. The infection is most frequently acquired by ingesting food or water contaminated by pig faeces, and it may be asymptomatic or may cause acute diarrhoea. Specific antibiotic treatment is efficacious, and it is important to consider the risk of this parasitic disease in susceptible patients presenting with bloody diarrhoea. PMID:15112068

    Full Text Available The laparoscopic approach for the groin hernia repair has several advantages: decreased immediate and late postoperative pain, less numbness in inguinal aria, less mesh infection and a rapid recovery. However the good outcomes are not granted, and there are some key points to be followed for better postoperative results. The aim of this video is to highlight these TAPP (TransAbdominal Pre-Peritoneal related key points, from the operative indication, pre operative preparation and surgical procedure, until the post operative follow up.

    Full Text Available Primary peritoneal serous carcinoma (PPSC is a rare primary malignancy that diffusely involves the peritoneum, indistinguishable clinically and histopathologically from primary serous ovarian carcinoma. The origin of PPSC has not been well characterized. Here we present a case of PPSC diagnosed in ultrasonography-guided fine needle aspiration cytology (FNAC in a 76- old female presenting with ascites, abdominal pain, distension and constipation. PPSC is an unusual tumour but cytomorphology is distinctive enough to diagnose preoperatively. In the case report hereby described PPSC is an inoperable malignancy, hence chemotherapy and palliative care are the only offered treatment.

    AIM: To study the effects of chitosan gel and blending chiston/gelatin film on preventing peritoneal adhesion in rats.METHODS: SD rats were randomly divided into 2groups, group A treated with chitosan gel and group B with blending chiston/gelatin film. In group A, rats were randomly subdivided into 3 subgroups as groups A1,A2 and A3, and different methods were used to induce peritoneal adhesions at the dead end of vermiform process in each group as follows: Group A1 with trauma,A2 with talc powder and A3 with ligation of blood vessel.In each subgroup, rats were redivided into control group and experimental group whose treated vermiform processes were respectively coated with chitosan gel and normal saline immediately after the adhesioninduced treatments. In group B, all the rats received traumatic adhesion-induced treatments and then were randomly divided into 4 groups (groups B1, B2, B3, B4).Group B1 served as control group and were coated with normal saline in the vermiform processes immediately after the treatments, and groups B2, B3 and B4 with 100% chitosan film, chitosan film containing 10% gelatin and chiston film containing 50% gelatin, respectively.At 2 and 4 wk after the above treatments, half of the rats in each terminal group were belly opened, and the peritoneal adhesive situation was graded and histopathological changes were examined.RESULTS: (1) In group A, regarding peritoneal adhesion situation: At both 2 and 4 wk after the treatments, for groups A1 and A3, the adhesive grades of experimental groups were significantly lower than those of the control group (2 wk:H=4.305, P<0.05 for A1, H = 6.743, P< 0.01 for A3; 4 wk:H= 4.459, P < 0.05 for A1,H=4.493, P < 0.05 for A3). However, of group A2, there was no significant difference between the experimental and control groups (2 wk:H= 0.147, P > 0.05; 4 wk:H=1.240, P>0.05). Regarding pathological changes:In groups A1 and A3, the main pathological change was fibroplasia. In group A2, the main

    Full Text Available We describe a rare case of fatal disseminated tuberculous peritonitis in a young woman with rapid progressive clinical course following spontaneous abortion of 20-week gestation. Clinical and laboratory findings were initially unremarkable. She underwent diagnostic laparoscopy which revealed numerous tiny implants on the peritoneum and viscera. Histopathology showed chronic caseating granulomas, and the tissue culture grew Mycobacterium tuberculosis. At fifth day of the antituberculous treatment multiorgan failure occurred in terms of pulmonary, hepatic, and renal insufficiency. She developed refractory metabolic acidosis with coagulopathy and pancytopenia, and she died of acute respiratory distress syndrome and septic shock on her twelfth day of hospitalization.

    The pathogenicity of enterococci in intraabdominal sepsis has not been clarified. Therefore, fecal-type peritonitis was induced in rats by intraperitoneal injection of barium sulfate along with a bacterial inoculum consisting of Escherichia coli, Bacteroides fragilis, and Clostridium perfringens with or without Streptococcus faecalis. Mortality at 19 d and characteristics of intraabdominal abscesses in survivors at 19 d were analyzed. The presence of S. faecalis in the original inoculum was significantly associated with death or large (greater than 20 mm) abscess formation when these two end points were examined together. S. faecalis may synergize with other bacteria in intraabdominal sepsis to augment morbidity and possibly mortality. PMID:2543707
