    The process of continuous ambulatory peritoneal dialysis has provided a useful, relatively inexpensive, and safe alternative for patients with end-stage renal disease. Infectious peritonitis, however, has limited a more widespread acceptance of this technique. The definition of peritonitis in this patient population is not universally accepted and does not always include the laboratory support of a positive culture (or Gram stain). In part, the omission of clinical microbiological findings stems from the lack of sensitivity of earlier microbiological efforts. Peritonitis results from decreased host phagocytic efficiency with depressed phagocytosis and bactericidal capacity of peritoneal macrophages. During episodes of peritonitis, fluid movement is reversed, away from the lymphatics and peritoneal membrane and toward the cavity. As a result, bloodstream infections are rare. Most peritonitis episodes are caused by bacteria. Coagulase-negative staphylococci are the most frequently isolated organisms, usually originating from the skin flora, but a wide array of microbial species have been documented as agents of peritonitis. Clinical microbiology laboratories need to be cognizant of the diverse agents so that appropriate primary media can be used. The quantity of dialysate fluid that is prepared for culture is critical and should constitute at least 10 ml. The sensitivity of the cultural approach depends on the volume of dialysate, its pretreatment (lysis or centrifugation), the media used, and the mode of incubation. The low concentration of microorganisms in dialysate fluids accounts for negative Gram stain results. Prevention of infection in continuous ambulatory peritoneal dialysis patients is associated with the socioeconomic status of the patient, advances in equipment (catheter) technology, and, probably least important, the application of prophylactic antimicrobial agents.

    ABSTRACT Burkholderia cepacia (B cepacia) is a rare opportunistic pathogen in continuous ambulatory peritoneal dialysis (CAPD) peritonitis. We describe the first case of repeated B cepacia CAPD peritonitis, occurring in an outpatient environment, treated with antimicrobial medication without peritoneal catheter removal. B cepacia may lead to repeat infection, therefore, we should insist on catheter removal during each peritonitis episode. PMID:26426187

    Leptin is a 16-kd protein that increases energy expenditure and limits food intake. Serum leptin (S-leptin) is elevated in dialysis patients, and little data have been reported on leptin clearance (Cl) during dialysis. We analyzed the peritoneal dialysis (PD) Cl of leptin in 15 continuous ambulatory peritoneal dialysis (CAPD) patients and compared the results to beta(2)-microglobulin (beta(2)-m), urea, and creatinine PD Cl. S-leptin was significantly elevated (Kruskal-Wallis, P < 0.005) in CAPD women (58.4 +/- 42.4 [SE] microg/L, n = 5) as compared with CAPD men (13.9 +/- 7.1, n = 10) and with healthy women (11.0 +/- 1.4, n = 13) and men (5.1 +/- 0. 9, n = 14). Correlations were found between percent of fat mass and S-leptin (P < 0.05); between S-leptin and the 24-hour PD leptin (P < 0.05); and between dialysate-to-plasma (D/P) beta(2)-m and D/P leptin (P < 0.01). PD leptin Cl (1.80 +/- 0.43 mL/min/1.73 m(2)) was higher than beta(2)-m Cl (1.22 +/- 0.31) (P < 0.01), but reduced as compared with urea Cl (8.84 +/- 1.20) (P < 0.005) and creatinine Cl (7.71 +/- 0.99) (P < 0.005). These results indicate that leptin is eliminated through the peritoneum membrane. However, peritoneal leptin clearance, as beta(2)-m, appears to be clearly restricted as compared with peritoneal transport of smaller molecules. Hence, leptin could use the same diffusion transport pathway as beta(2)-m. In addition, leptin, which has a higher molecular weight than beta(2)-m, was significantly more eliminated into the peritoneal dialysate. More studies are necessary to clarify whether this is an active leptin elimination process by peritoneal secretion or by a different restriction coefficient of diffusion through the peritoneum membrane.

    Mycobacterium fortuitum, an environmental organism, is capable of producing a variety of clinical infections such as cutaneous infections, abscesses and nosocomial infections. Rarely, it has been a documented as a cause of peritonitis in patients receiving continuous ambulatory peritoneal dialysis (CAPD). Continuous Ambulatory Peritoneal dialysis (CAPD) is one of the treatment options which are used for patients with end-stage renal disease (ESRD). Although peritonitis rates have declined in parallel with advances in peritoneal dialysis (PD) technology, peritonitis remains a leading complication of CAPD and it is the major cause for transfer to other methods of dialysis. We are reporting a case of M. fortuitum peritonitis in a patient who was undergoing CAPD, which was successfully treated. This case emphasizes the importance of mycobacterial cultures in patients with CAPD-associated peritonitis, whose routine cultures may yield no organisms. PMID:24551685

    We present a case where Bacillus cereus was determined to be the causative agent of relapsing peritonitis in a patient on continuous ambulatory peritoneal dialysis (CAPD). The patient, a 70-year-old man from the Faroe Islands, was admitted with relapsing peritonitis four times over a 3-month period. Peritoneal cultures were positive for growth of B. cereus, a rare bacterial cause of peritonitis. The cultures demonstrated susceptibility to vancomycin, and therefore the patient was treated with intraperitoneal vancomycin, intraperitoneal gentamycin and oral ciprofloxacin. As a result of the relapsing B. cereus peritonitis diagnosis and a CT scan showing contraction of the peritoneum after longstanding inflammation, the peritoneal catheter was removed and the patient converted to haemodialysis. To date, the patient has not been readmitted due to peritonitis. A lack of proper hygiene when changing the dialysis bag was the suspected source of infection with B. cereus. PMID:27118739

    The pharmacokinetics of cefepime were studied in 10 male patients receiving continuous ambulatory peritoneal dialysis therapy. Five patients received a single 1,000-mg dose and the other five received a single 2,000-mg dose; all doses were given as 30-min intravenous infusions. Serial plasma, urine, and peritoneal dialysate samples were collected; and the concentrations of cefepime in these fluids were measured over 72 h by using a high-performance liquid chromatographic assay with UV detection. Pharmacokinetic parameters were calculated by noncompartmental methods. The peak concentrations in plasma and the areas under the plasma concentration-versus-time curve for the 2,000-mg dose group were twice as high as those observed for the 1,000-mg dose group. The elimination half-life of cefepime was about 18 h and was independent of the dose. The steady-state volume of distribution was about 22 liters, and values for the 1,000- and 2,000-mg doses were not significantly different. The values for total body clearance and peritoneal dialysis clearance were about 15 and 4 ml/min, respectively. No dose dependency was observed for the clearance estimates. Over the 72-h sampling period, about 26% of the dose was excreted intact into the peritoneal dialysis fluid. For 48 h postdose, mean concentrations of cefepime in dialysate at the end of each dialysis interval exceeded the reported MICs for 90% of the isolates (MIC90s) for bacteria which commonly cause peritonitis resulting from continuous peritoneal dialysis. A parenteral dose of 1,000 or 2,000 mg of cefepime every 48 h would maintain the antibiotic levels in plasma and peritoneal fluid above the MIC90s for the most susceptible bacteria for the treatment of systemic and intraperitoneal infections [corrected].

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

    Nine nurses were interviewed to determine nurses' experiences of teaching patients to use continuous ambulatory peritoneal dialysis (CAPD). The material was analyzed using content analysis. Data were sorted into four themes and ten subthemes. The themes were presented as follows: Importance of language, individualized teaching, teaching needs and structure of care in teaching. The findings highlighted important insights into how nurses experience teaching patients to perform CAPD. The study revealed some barriers for the nurses during teaching. The major barrier was shortage of Arabic speaking nursing staff. Incidental findings involved two factors that played an important role in teaching, retraining and a special team to perform pre-assessments, including home visits. In conclusion, the findings of this study showed several factors that are considered as barriers for the nurses during teaching the CAPD patients and the need to improve the communication and teaching in the peritoneal dialysis units, including the importance of individualized teaching.

    We studied single-dose cefazolin (CFZ) and cephalexin (CPX) kinetics in continuous ambulatory peritoneal dialysis (CAPD) patients to establish therapeutic guidelines for two cephalosporins commonly used to treat peritonitis in these patients. CFZ, 10 mg/kg, was given intravenously and intraperitoneally, while CPX, 500 mg, was given orally. CFZ led to serum concentrations of 25 microgram/ml at 24 hr, with a half-life (t 1/2) of 33 hr. CAPD accounted for only 20% of total body clearance. When CFZ was given intraperitoneally, 74% of the dose was absorbed and similar serum concentrations had much the same t 1/2. CPX, on the other hand, had a serum t 1/2 of 8.6 hr and resulted in much lower peritoneal concentrations than CFZ. The kinetic principal of superposition provided a model for the prediction of plasma concentrations after repeated intraperitoneal doses of CFZ. The model predicts that a 10-mg/kg intraperitoneal loading dose, followed by 5-mg/kg doses in each exchange the first day and 2.5-mg/kg doses thereafter, will lead to steady-state plasma concentrations of 50 to 65 microgram/ml. The data suggest that CFZ needs be given only intraperitoneally at doses lower than those in current use. CPX probably adds little to the treatment of peritonitis. PMID:6848301

    Micrococcus strains which are the normal flora members of skin, mucosa and oropharynx, may lead to infections associated with intravenous catheter, chronic ambulatory peritoneal dialysis, venticular shunt and prosthetic valve. In this paper, a case of peritonitis due to Kocuria rosea of Micrococcea family, in a patient undergoing continuous ambulatory peritoneal dialysis (CAPD), was presented. Fiftysix years old female patient was admitted to the hospital by complaints of abdominal pain, nausea and fever. The patient was undergoing CAPD due to chronic renal failure for one and a half year and turbidity was detected in the peritoneal fluid during dialysis. Examination of the peritoneal fluid revealed 1800 cells/mm3, with no evidence of bacteria in Gram and Ziehl-Neelsen stained smears. No bacterial growth was detected in conventional culture media, however, bacteria was isolated from the peritoneal fluid culture on second day by Bactec (Becton Dickinson, USA) automated blood culture system. By means of API identification system (bioMerieux, USA), the causative agent was identified as Kocuria rosea. The patient was successfully treated with intraperitoneal teicoplanin (4 x 40 mg) for 14 days. In conclusion, in patients undergoing CAPD, rare pathogens should be considered in case of peritonitis and peritoneal fluid samples should be inoculated into automated culture systems. PMID:19621623

    Continuous ambulatory peritoneal dialysis is a new and increasingly popular method of routine dialysis, but its effect on renal transplantation is uncertain. A non-randomised comparison was made of the outcome of grafting in patients who had been treated before transplantation with continuous ambulatory peritoneal dialysis with that in patients treated with haemodialysis. During the five years, 1979-84, after continuous ambulatory peritoneal dialysis was introduced to Newcastle upon Tyne 220 patients have received transplants after either continuous ambulatory peritoneal dialysis (61 patients) or haemodialysis (159 patients). During follow up no significant differences occurred in survival of patients or grafts between the two treatment groups. One year after transplantation the percentages of survivors who had received continuous ambulatory peritoneal dialysis and haemodialysis were 88% and 91% respectively, and overall graft survival was 66% and 72%, respectively. A multiple regression model was used to allow for differences among patients--for example, duration of dialysis and number of preoperative transfusions--on the survival of grafts. When only first cadaver grafts were considered (in 152 patients) graft survival (non-immunological failures excluded) was not significantly different between the patients treated with continuous ambulatory peritoneal dialysis and haemodialysis. Continuous ambulatory peritoneal dialysis is not a risk factor in renal transplantation, and its continued use in treatment of potential renal graft recipients is recommended. PMID:3931765

    The effects of continuous ambulatory peritoneal dialysis on parathyroid hormone (PTH) and mineral metabolism were evaluated in ten patients. Utilizing a PTH radioimmunoassay, which measures both intact hormone and carboxyl-terminal PTH fragments, it was found that the mean clearance of immunoreactive parathyroid hormone was 1.5 +/- 0.73 ml/min (SEM) yielding a daily net removal of 13.6 +/- 3.2% of estimated total extracellular parathyroid hormone. Gel electrophoresis of the dialysate revealed the presence of both intact parathyroid hormone and fragments in a similar pattern to that of peripheral plasma. Normal levels of 25-(OH) vitamin D and vitamin D binding protein were observed prior to the initiation of continuous ambulatory peritoneal dialysis and following 6 months of treatment. Timed dialysate collections (N = 93) demonstrated a daily calcium influx of only 9.9 +/- 9.7 mg. The daily removal of phosphorus was 308.4 +/- 15.5 mg. Despite elevated serum magnesium levels in all patients, the net daily removal was inadequate (31.2 +/- 15.5 mg). It was concluded that: (1) Unlike chronic hemodialysis, continuous ambulatory peritoneal dialysis removes significant amounts of parathyroid hormone. (2) Normal 25-(OH) vitamin D and vitamin D binding protein levels are maintained with continuous ambulatory peritoneal dialysis despite large protein losses. (3) Substantial amounts of phosphorus are removed with continuous ambulatory peritoneal dialysis but not to an extent that precludes use of phosphorus binders. (4) Dialysate containing lower magnesium and possibly higher calcium concentrations should be made available to improve mineral homeostasis. PMID:6897087

    A 61-year-old female was diagnosed as having end-stage renal failure developed dyspnea soon after introduction of continuous ambulatory peritoneal dialysis (CAPD). Chest X-ray showed a right-side massive pleural effusion. Pleuro peritoneal communication was suspicious, because the hydrothorax significantly improved by the stop of CAPD. We performed video-assisted thoracic surgery. Using indigo carmine containing peritoneal dialysis fluid through a CAPD catheter, we found a fistula on the diaphragm from which blue dialysis solution flowed out like a fountain. The fistula of the diaphragm was directly closed with a surgical stapler and covered using cellulose oxidized (Surgicel) and fibrin glue. She could restart CAPD on postoperative days 7, and no recurrence of hydrothorax has been detected for 10 months after surgical treatment. PMID:22314177

    We describe here hydrothorax that occurred in a patient on continuous ambulatory peritoneal dialysis (CAPD) and highlight the problems of diagnosis and management. A 48 years-old man with history of obstructive uropathy secondary to urolithiasis was stared on CAPD when he reached end-stage renal failure. Two months later, he was admitted with two days history of shortness of breath on exertion and dry cough increasing in supine position. Chest examination was suggestive of right sided pleural effusion confusion confirmed by chest X-ray. Radioisotope Technetium 99m labeled albumin instilled through the peritoneal catheter was detected in the right pleural fluid confirming the peritoneo-pleural leak. The peritoneal dialysis (PD) was discontinued and the patient was switched to hemodialysis. The pleural effusion subsided and has not recurred for the following three years. PMID:18212427

    Background: Peritoneal dialysis has a number of complications including increased blood glucose. Although exercise has been suggested to resolve this complication, most patients are not active. The present study aimed at determining the effects of twice-weekly, 40-min sessions of pedaling on a stationary bicycle on mean fasting blood sugar (FBS) and 2-h postprandial blood sugar (PPBS) among continuous ambulatory peritoneal dialysis patients. Materials and Methods: In this clinical trial, convenience sampling was used to select 22 patients [age: 51.4 (12.3) years] undergoing continuous ambulatory peritoneal dialysis [mean duration: 12.5 (8.5) months] from university hospitals in Isfahan, Iran. The subjects were randomly divided into two groups (test and control). The test group participated in an 8-week exercise program in which they pedaled a stationary bicycle with an intensity of four on Borg Scale of Perceived Exertion. FBS and PPBS were measured at baseline and at the end of the 8th and 16th sessions of exercise. Data were analyzed with Student's t-test and repeated measures analysis of variance. Results: After the eighth session, the mean FBS and PPBS levels were lower in the test group than in the control group. However, the differences were not statistically significant. After 16 sessions of exercise, the mean FBS and PPBS levels in the intervention group were significantly less than the in control group. Conclusions: Forty minutes of pedaling on a stationary bicycle for two times a week can significantly reduce mean FBS and PPBS levels in continuous ambulatory peritoneal dialysis patients.

    A 46-years-old woman admitted for induction of continuous ambulatory peritoneal dialysis (CAPD). When peritoneal functional test was performed, dyspnea was occurred. Chest X-ray and chest computed tomography (CT) scan revealed massive right hydrothorax. Technetium-99m macroaggregated albumin scintigraphy showed communication between abdominal cavity and thoracic cavity. The thoracoscopic diaphragmal repair was performed. After CAPD was started, right hydrothorax occurred again. Re-repair of the diaphragm was performed in small thoracotomy and small hole was revealed. The hole was sutured and diaphragm was coverd by fibrin glue and polyglycolacid (PGA) felt all over. Since then, CAPD was continued successfully. Thoracoscopic surgery is less invasive and appropriate therapy for this case. It is important that the diaphragm will be covered all over by fibrin glue and PGA sheet because even pin-hole makes recurrence. For detect of the communicative portion, use of indigocarmin and examination of glucose concentration in the pleural effusion were effective. PMID:19764504

    Two hundred and twenty nine consecutive patients (129 men, mean age 45) were reviewed 12 to 65 months after starting treatment with continuous ambulatory peritoneal dialysis (CAPD) from January 1979 to December 1983. They received CAPD for a mean of 19.8 (range 0.5-62) months. Actuarial patient survival was 79% at 24 months and 72% at 36 months. Half of the 46 deaths were related to cardiovascular disease, while eight patients died of abdominal complications, including three patients with peritonitis. Peritonitis occurred at a rate of one episode per 35 patient weeks, and 88% of episodes were cleared by one or more courses of antibiotics. This still left peritonitis as the commonest cause of failure of CAPD, leading to a permanent change of treatment in 44 patients and temporary interruption in a further 25. CAPD remains a reasonable medium term treatment in chronic renal failure. Despite the persisting problem of peritonitis the results are comparable with those achieved by haemodialysis, and CAPD has become the treatment of first choice for end stage renal failure in Newcastle. In younger patients judged unsuitable for transplantation and facing long term dialysis, however, haemodialysis is preferred. PMID:3094723

Despite adequate treatment both succumbed to their illness. Abdominal pathology, especially mesenteric ischemia leading to gut infarction, should be considered in patients with refractory peritonitis. PMID:26664217

    Introduction 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 Methods 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. Results 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). Conclusion 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

    Cefradine and co-trimoxazole pharmacokinetics were studied in a patient with peritonitis that complicated continuous ambulatory peritoneal dialysis (CAPD). Concentrations in the plasma reached after oral administration of 500 mg cefradine four times daily and 400/80 mg co-trimoxazole four times daily were for cefradine 100 micrograms/ml, for trimethoprim 15 micrograms/ml, and for sulfamethoxazole 100 micrograms/ml, respectively. In the dialysate concentrations were reached of 35-70 micrograms/ml cefradine, 2-5 micrograms/ml trimethoprim and 8-17 micrograms/ml sulfamethoxazole. The values for sulfamethoxazole are regarded too low to be clinically effective. Half-lives, protein binding values and CAPD clearances are presented. Low CAPD clearances were obtained during the night and high values during the day. The dosage yielded too high plasma trimethoprim concentrations, while sulfamethoxazole dialysate concentrations were too low. It seems questionable therefore whether co-trimoxazole can be used orally for the treatment of CAPD peritonitis. PMID:3495778

    ♦ Introduction and aim: Continuous ambulatory peritoneal dialysis (CAPD) is not a frequently used modality of dialysis in many parts of Africa due to several socio-economic factors. Available studies from Africa have shown a strong association between outcome and socio-demographic variables. We sought to assess the outcome of patients treated with CAPD in Limpopo, South Africa. ♦ Methods: This was a retrospective study of 152 patients treated with CAPD at the Polokwane Kidney and Dialysis Centre (PKDC) from 2007 to 2012. We collected relevant demographic and biochemical data for all patients included in the study. A composite outcome of death while still on peritoneal dialysis (PD) or CAPD technique failure from any cause requiring a change of modality to hemodialysis (HD) was selected. The peritonitis rate and causes of peritonitis were assessed from 2008 when all related data could be obtained. ♦ Results: There were 52% males in the study and the average age of the patients was 36.8 ± 11.4 years. Unemployment rate was high (71.1%), 41.1% had tap water at home, the average distance travelled to the dialysis center was 122.9 ± 78.2 kilometres and half the patients had a total income less than USD ($)180 per month. Level of education, having electricity at home, having tap water at home, body mass index (BMI), serum albumin and hemoglobin were significantly different between those reaching the composite outcome and those not reaching it (p < 0.05). The overall peritonitis rate was 0.82/year with 1-year, 2-year and 5-year survival found to be 86.7%, 78.7% and 65.3% (patient survival) and 83.3%, 71.7% and 62.1% (technique survival). Predictors of the composite outcome were BMI (p = 0.011), serum albumin (p = 0.030), hemoglobin (p = 0.002) and more than 1 episode of peritonitis (p = 0.038). ♦ Conclusion: Treatment of anemia and malnutrition as well as training and re-training of CAPD patients and staff to prevent recurrence of peritonitis can have positive

    Peritoneal dialysis can worsen dislipemia, which is frequent in chronically uremic patients. In order to verify the therapeutic possibilities, we retrospectively studied 20 chronically uremic patients who had been previously treated with continuous ambulatory peritoneal dialysis (CAPD) and who had developed an IV-type dislipemia. Twelve have continued CAPD treatment and have been simultaneously treated with simvastatin; 8 have withdrawn from CAPD and have begun HD, without any antidislipemic pharmacological support. The results, after 3, 6, 12, and 18 months of treatment, showed the following: in patients treated with CAPD and simvastatin, highly significant decreases were noted in total cholesterol (T-cho) and triglycerides (TG) (p < 0.001), and highly significant increases were noted in HDL-cholesterol (HDL-cho) (p < 0.005) and apolipoprotein-A1 (Apo-A1) (p < 0.01). In patients treated with HD, only slightly significant decreases were noted in T-cho (p < 0.01) and TG (p < 0.02), a slightly significant increase in Apo-A1 (p < 0.05), and no significant change in HDL-cho. Apolipoprotein-B showed no change in the two groups. Therefore, patients undergoing CAPD, with dislipemia only, can continue the treatment, because simvastatin is capable of correcting dislipemia, while those patients who have displemia as well as other complications strictly due to CAPD must abandon treatment and must be transferred to extracorporeal methods.

    We herein describe a case of tension hydrothorax that occurred on continuous ambulatory peritoneal dialysis (CAPD), highlighting the problems of diagnosis and a novel management. A 38-year-old male with end-stage renal disease (ESRD) due to diabetes mellitus developed dyspnea and poor drainage after 13 months of CAPD. Chest X-ray revealed massive right-sided hydrothorax and mediastinal shift. He underwent emergency thoracentesis and pleural fluid showed a high level of glucose. Pleuroperitoneal communication was strongly suspected, although the methylene blue test was negative. We temporarily performed hemodialysis. Two weeks later, PD was resumed but failed with recurrent right-side hydrothorax in 4 months. The pleuroperitoneal leakage was definitively confirmed by video-assisted thoracoscopic surgery (VATS). Diaphragmatic repair and pleurodesis with hypertonic glucose were performed. There was no recurrence of hydrothorax after treatment. PMID:26784913

    The aim of this study is to quantify the intelligence output in our pediatric population on continuous ambulatory peritoneal dialysis (CAPD) treatment. A total of 30 children were studied, with an age range of eight to 18 years. For evaluating a global intelligence quotient (IQ), the Wechsler test was applied according to their age. And, as a complement, a Bender test was also requested to deny or confirm brain damage. The Wechsler test showed an average intelligence quotient in most of the children (76.7%); a small group (16.7%) was classified as dull normal, 1 child had mild retardation, and 1 was borderline. All of them had a Bender test that did not correlate with brain damage. Most of them maintained a very high verbal IQ, but, when the performance IQ was qualified, 34% got a low score, and a certain difficulty in solving this part of the test was observed. Maybe this was influenced by chronicity of the sickness and/or the blood urea nitrogen level. In conclusion, the child's plasticity is his best quality to cope with uremia and the alterations caused by it. Therefore the idea is to consider the intelligence quotient as the capacity that the subjects have to use their own resources to cope with their environment. And, even though the neurological alterations exist, the child's plasticity helps him/her maintain a good global intelligence quotient, even though he/she is not having immediate transplantation.

    The metabolic disturbances in glucose-6-phosphatase deficiency (von Gierke's disease) are the consequence of hypoglycemia, occurring mostly during the night. Continuous provision of glucose is the aim of every recently introduced treatment procedure. We studied the influence of continuous ambulatory peritoneal dialysis (CAPD) on the metabolic disturbances in a 42-year-old female patient with von Gierke's disease and end-stage renal disease. During six months of CAPD, there were no dialysis-related complications. The metabolic acidosis didn't worsen: arterial bicarbonate and lactate were not changed. Mean glycemia was 118.6 +/- 14.4 mg%. Total lipemia, cholesterol and triglycerides were not different from those before CAPD, despite the fact that all hypolipidaemic drugs were stopped. Three different exchange procedures were compared during the night: no dialysis, one exchange with a 2 L solution without buffer containing glucose 15 g/L and containing glucose 42.5 g/L. The results show that the 4.25% glucose solution prevents hypoglycaemia, and diminishes the increase in lactate and pyruvate concentration. Intraperitoneal glucose normalizes the plasma free fatty acid concentration. A very important result is the disappearance of hypo-insulinism. We conclude that, from a clinical point of view, CAPD is a well-tolerated treatment in von Gierke's disease. The limited results provide some evidence that the use of a 4.25% glucose solution as an overnight exchange, instead of the usual 1.5% solution, can prevent at least partly the glycogenolysis and consequently the metabolic disturbances of von Gierke's disease.

    As the number of human immunodeficiency virus (HIV) infected patients has increased in the U.S., the number of infected patients treated for end-stage renal disease (ESRD) has stabilized at about 1 to 2% of the hemodialyzed population. Little has been written regarding the role of continuous ambulatory peritoneal dialysis (CAPD) in the treatment of HIV infected patients with ESRD. To evaluate the effectiveness of CAPD as a long term therapy for HIV infected patients with ESRD, we reviewed our ESRD program's experience. We entered 392 patients from its inception in February 1984 until April 1992. Thirty-one, or 7.9% of our population were HIV infected. Twenty, or 64.5% had stage IV infection. Patients were entered into our chronic hemodialysis (HD) or CAPD program according to standard clinical criteria. Eight HIV infected patients elected to start CAPD, while 23 patients were treated exclusively with HD. The proportion of stage IV infected patients was similar in both treatment modality groups. HIV infected ESRD patients were younger than non-HIV infected patients (37.5 +/- 9.7 vs. 49.8 +/- 15.7 years, respectively, P < 0.0001) at the start of treatment. We used Cox regression techniques to analyze survival data. Mean survival time for our entire non-HIV infected ESRD population (N = 361) was 44.0 +/- 33.9 months. Mean survival time for HIV infected patients with ESRD was 15.5 +/- 9.9 months. Median survival for HIV infected ESRD patients was 13 months compared to 38 months for the non-infected population. As expected, mean survival time in HIV infected ESRD patients was significantly diminished compared to non-infected ESRD patients (P < 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8377381

    Recent studies suggest that the relationship of the net normalized protein catabolic rate (which is the normalized protein equivalent of nitrogen appearance [nPNA]) to the weekly clearance of urea normalized to total body water (Kt/V urea) in patients on continuous ambulatory peritoneal dialysis (CAPD) is curvilinear, rather than linear, as has been thought. The authors have reexamined the relationship of nPNA to weekly Kt/V urea in a CAPD population by cross-sectional analysis to see if the curvilinear definition of the relationship is as good as or better than the usual linear description. They also examined this relationship in the hemodialysis populations at the Dialysis Clinics Inc. in Columbia, Missouri, and in the Renal Kidney Disease Program in Minneapolis, Minnesota. It seems obvious that there should be a plateau of nPNA in each therapy because extension of linear regressions would predict protein intakes of normal individuals exceeding 8 g/kg/body weight/day. The authors compared their findings to other published results. Intuitively and analytically, the curvilinear relationships seem likely. The authors observed that the nPNA plateau is achieved at lower Kt/V in patients on CAPD than in those on hemodialysis, which is compatible with the peak concentration hypothesis. Asymptotes for CAPD and hemodialysis are similar. Weekly Kt/V urea requirements to achieve nPNA values at 95% of the asymptote are greater than those usually delivered. However, such nearly complete elimination of uremic appetite suppression may not be practical or necessary for achieving acceptable nutritional status and long-term survival in most patients. Optimum therapy may be well above adequate therapy relative to minimizing appetite suppression by uremia. PMID:8573843

    Peritonitis is the major complication of continuous ambulatory peritoneal dialysis (CAPD) and is caused predominantly by coagulase-negative staphylococci (CNS). Adherence to the silicone rubber Tenckhoff catheter has been identified as one factor in the pathogenesis and persistence of these infections. We have studied the adherence of CNS from patients and controls to silicone rubber in an in vitro model to determine whether this phenomenon can be modified by antibiotics. Adherence was strong for 7/27 (26%) CAPD isolates and for 3/27 (11%) of control strains. The strongly adherent CAPD isolates, when exposed to subinhibitory concentrations of vancomycin, cefuroxime, and ciprofloxacin, showed minimal alteration in adherence with vancomycin in both broth and used dialysate, whereas cefuroxime and ciprofloxacin both significantly reduced it. These observations may have implications for drug selection and prevention of CAPD peritonitis caused by CNS. PMID:2488193

    Anephric rats were maintained on continuous ambulatory peritoneal dialysis (CAPD). Peritoneal permeability was assessed during a standard 4-hour peritoneal equilibration test (PET) performed with Dianeal 3.86% (Baxter Healthcare, Deerfield, Illinois, U.S.A.). The effect of uremia on peritoneal permeability was evaluated in an experimental protocol in which each animal served as its own control. In each rat, PET1 (control) was performed before removal of kidneys and PET2 (uremia) was performed four days after removal of kidneys. Net ultrafiltration during a 4-hour exchange with Dianeal 3.86% was higher during PET1 (3.8 +/- 2.3 mL) than during PET2 (-1.3 +/- 3.3 mL), p < 0.05. Peritoneal permeability to urea and glucose was similar in both series. Transperitoneal equilibration of creatinine concentration was faster in uremic animals: D/P at 4 hours was 0.94 +/- 0.06 during PET2 versus 0.77 +/- 0.08 during PET1, p < 0.001. The opposite difference was seen for total protein: D/Px 1000 after a 4-hour dwell was 51.4 +/- 19.8 during PET2 versus 70.3 +/- 12.9 during PET1, p < 0.05. Our results show that uremia modifies the permeability of the peritoneum to both water and solutes. PMID:10682068

    This paper reports a comprehensive comparison for mortality and technique failure rates between automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) in Taiwan. A propensity-score matched cohort study was conducted by retrieving APD and CAPD patients identified from the Taiwan National Health Insurance Research Database between 2001 and 2010. The main outcomes were the 5-year mortality and technique failure rates. Further analyses were then carried out based upon the first (2001-2004), second (2005-2007), and third (2008-2010) sub-periods. Similar baseline characteristics were identified for APD (n = 2,287) and CAPD (n = 2,287) patients. The proportion on APD therapy increased rapidly in the second sub-period. As compared to CAPD patients of this sub-period, APD patients had a significantly higher risk of mortality (HR, 1.37; 95% CI 1.09-1.72; p < 0.01) and technique failure (HR, 1.43; 95% CI, 1.10-1.86; p < 0.01), particularly in the first year after peritoneal dialysis commencement. However, APD patients had similar mortality and technique failure rates to those of CAPD patients throughout the full sample period and the first and third sub-periods. These findings do not suggest the presence of a clear advantage of CAPD over APD. Differences observed between these two modalities might be attributed to specials circumstances of sub-periods.

    Abstract Health-related quality of life (HRQOL) is an important clinical outcome for dialysis patients. However, relative superiority in HRQOL between automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) are not clearly known. We compared HRQOL over time between APD and CAPD patients and evaluated factors associated with HRQOL. All 260 incident patients initiating APD or CAPD at multiple centers throughout Korea were prospectively enrolled in this study between October 2010 and February 2013. HRQOL, depressive symptoms, and renal treatment satisfaction were assessed 1 and 12 months after the start of dialysis by the Kidney Disease Quality of Life Short Form 36 (KDQOL-36), the Beck Depression Inventory (BDI), and the Renal Treatment Satisfaction Questionnaire (RTSQ), respectively. Of 196 patients who completed all questionnaires and did not change the peritoneal dialysis (PD) modality during the 1-year follow-up period, 160 were matched. APD patients showed better baseline HRQOL than CAPD patients for the symptoms, patient satisfaction, pain, and social function domains. There were no differences in HRQOL between the 2 groups at 12 months, and CAPD patients had significantly greater improvements in symptoms (P = 0.02), the mental composite summary (P = 0.03), and health status domains (P = 0.03) than APD patients. There were similar improvements in depressive symptoms (P = 0.01) and patient satisfaction with treatment (P = 0.01) in CAPD and APD patients. Interestingly, depressive symptoms, not PD modality, was the most influential and consistent factor for HRQOL. Despite the spontaneous improvement of depressive symptoms, considerable PD patients still had depressive symptoms at the 1-year appointment. APD has no advantage over CAPD for HRQOL. Considering the substantial negative effect of depressive symptoms on HRQOL, it is important to evaluate PD patients for depression and to treat those with depression to

    Objective: Hypertension and hyperlipidemia are two major risk factors for cardiovascular disease in continuous ambulatory peritoneal dialysis (CAPD) patients. This study was designed to investigate the effect of omega-3 fatty acids on blood pressure (BP) and serum lipids in CAPD patients. Methods: This study was a randomized double-blind clinical trial in which 90 CAPD patients were randomly assigned to either the omega-3 or the placebo group. Patients in omega-3 group received 3 g/day omega-3 for 8 weeks, whereas patients in the control group received placebo. At baseline and at the end of 8 weeks, the patients’ BP was controlled, and serum biochemistry was measured. Findings: Mean systolic BP decreased (–22.2 ± 14.2 mmHg) in the omega-3 group at the end of the study while in the placebo group increased (+0.5 ± 30.2 mmHg) (P < 0.0001). Mean diastolic BP of the omega-3 group decreased more (–11.95 ± 11.9 mmHg) comparing with the placebo group (–1.1 ± 17.3 mmHg) (P = 0.001). There were no significant differences between the two groups in mean changes in serum triglyceride, and total, high-density lipoprotein, and low-density lipoprotein cholesterol. Conclusion: The results of this study indicate that omega-3 reduced BP significantly but had no effect on lipid profile in our CAPD patients. PMID:26312252

    In the study reported here 55 spouses of patients living with end-stage renal disease (ESRD) were investigated with respect to coping strategies and health-related quality of life. Findings from the study were compared to two random samples of the Swedish general population (n = 454, and n = 1200). The study design was correlational and comparative. Coping was measured by the Jalowiec Coping Scale, and quality of life (QoL) by the Swedish Health-Related Quality of Life Survey (SWED-QUAL). Data were analysed using a number of statistical tests including Pearson's product moment correlations, Student's t-test and two way ANOVAs. The combined sample of spouses used significantly more optimistic and palliative coping than the general population, but less confrontative, self-reliant, evasive and emotive coping. In the study fatalistic, evasive and emotive coping was associated with low perceived efficiency in handling various aspects of the partners' situation. The male spouses used significantly less optimistic, supportive and palliative coping than did the female spouses. The spouses of transplant patients had better overall quality of life than the continuous ambulatory peritoneal dialysis and haemodialysis spouse groups, most likely due to the lower age of the former group. The study findings suggest that emotive, evasive and fatalistic coping are less than optimal ways to deal with problems occasioned by the partner's treatment. PMID:10849152

    Culture-negative peritonitis is a major complication for patients on continuous ambulatory peritoneal dialysis (CAPD) and precludes organism-specific therapy. The aim of the present study was to compare inoculation of 10 ml of CAPD effluent into BacT/Alert blood culture bottles (FAN [fastidious antimicrobic neutralizing], BacTAlert aerobic [BTA], and BacT/Alert anaerobic [BTAn] bottles) to our conventional method of using 50 ml of concentrated CAPD effluent to inoculate peptone broth bottles (BD bottles) and MacConkey agar and blood agar medium (BA-MAC). The FAN, BTA, and BTAn bottles were monitored automatically in the BacT/Alert blood culture instrument. A total of 207 CAPD effluents were studied, and in 97 bacteria were detected by at least one method. Compared to BTA bottles (79 of 97; 81.4%), BTAn bottles (78 of 97; 80.4%), and BD bottles (88 of 97; 90.7%), the single best broth medium for detecting bacterial growth in CAPD effluents was the FAN bottle (90 of 97 effluents; 92.8%). A total of 125 bacterial species were detected by any method, and the majority (91.8%) of CAPD effluents were infected with a single species. A combination of FAN and BTAn bottles detected 111 of 125 (88.8%) of all organisms, whereas a combination of BD bottles and BA-MAC detected 107 of 125 (85.6%) of all organisms. One or more organisms that would have been completely missed by the conventional method with BD bottles and BA-MAC were detected in 18 CAPD effluents. Of these 18 CAPD effluents, 6 showed no growth by the conventional method with BD bottles and BA-MAC. On the basis of our data, the most sensitive and least labor intensive method was direct inoculation of 10 ml of CAPD effluent into a FAN bottle and a BTAn bottle, which could be automatically monitored by the BacT/Alert blood culture instrument. On the basis of case definitions for peritonitis, the sensitivities and specificities of the methods with FAN and BTAn bottles and with BD bottles and BA-MAC were 81.1 and 98

    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 < 0.01) or APD (60 %) (p < 0.04). Patients on APD were more likely to have RLS compared to those on HD or CAPD (p < 0.04) (50 vs. 23 vs. 33 %). No differences among the modalities were found in bruxism, EDS, 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

CAPD samples were inoculated into two AS bottles-one anaerobic, one aerobic-and a Septichek bottle; samples were also examined for cell count, Gram stain, and direct culture. Culture bottles were then subcultured onto various media, and any organisms isolated were identified. After routine culture, GLC was performed on culture fluid in the anaerobic AS and Septichek bottles. When volatile fatty acids were detected, the broths were cultured anaerobically on specialised medium for a further five days. RESULTS: 147 organisms were isolated from the 168 samples: 96 (57%) yielded growth of significant organisms by direct culture, as compared to 129 (76.8%) by both AS and Septichek. There was no significant difference in isolation rates between AS and Septichek, but time to detection was more rapid with the AS system (p < 0.002). GLC showed volatile fatty acid in 15 specimens; of these, 14 subsequently grew anaerobic organisms. CONCLUSIONS: AS was comparable to Septichek for numbers of isolations. Speed to detection was faster with the AS, which may be an advantage in management of patients with CAPD peritonitis. GLC showed anaerobes in several cases which would not have been detected without prolonged anaerobic culture; thus anaerobic cultures are recommended for patients who are unresponsive to antimicrobials or who have evidence of bowel perforation.

    Background Endotoxemia is exaggerated and contributes to systemic inflammation and atherosclerosis in patients requiring continuous ambulatory peritoneal dialysis (CAPD). The risk of mortality is substantially increased in patients requiring CAPD for >2 years. However, little is known about the effects of long-term CAPD on circulating endotoxin and cytokine levels. Therefore, the present study evaluated the associations between plasma endotoxin levels, cytokine levels, and clinical parameters with the effects of a short-dwell exchange on endotoxemia and cytokine levels in patients on long-term CAPD. Methods A total of 26 patients were enrolled and divided into two groups (short-term or long-term CAPD) according to the 2-year duration of CAPD. Plasma endotoxin and cytokine levels were measured before and after a short-dwell exchange (4-h dwell) during a peritoneal equilibration test (a standardized method to evaluate the solute transport function of peritoneal membrane). These data were analyzed to determine the relationship of circulating endotoxemia, cytokines and clinical characteristics between the two groups. Results Plasma endotoxin and monocyte chemotactic protein-1 (MCP-1) levels were significantly elevated in the long-term group. PD duration was significantly correlated with plasma endotoxin (r = 0.479, P = 0.016) and MCP-1 (r = 0.486, P = 0.012). PD duration was also independently associated with plasma MCP-1 levels in multivariate regression. Plasma MCP-1 levels tended to decrease (13.3% reduction, P = 0.077) though endotoxin levels did not decrease in the long-term PD group after the 4-h short-dwell exchange. Conclusion Long-term PD may result in exaggerated endotoxemia and elevated plasma MCP-1 levels. The duration of PD was significantly correlated with circulating endotoxin and MCP-1 levels, and was an independent predictor of plasma MCP-1 levels. Short-dwell exchange seemed to have favorable effects on circulating MCP-1 levels in

    This review surveys the dramatic worldwide expansion of the use of continuous peritoneal dialysis as maintenance renal replacement therapy for children with end-stage renal disease that has occurred during the past decade. Before 1982, fewer than 100 pediatric patients had been treated with continuous ambulatory peritoneal dialysis (CAPD), and continuous cycler peritoneal dialysis (CCPD) for children was virtually unknown. By the end of 1989 CAPD/CCPD was accounting for 50% of pediatric dialysis patients (less than 15 years old) in the United States, 65% in Canada, and 75% in Australia/New Zealand. Growth of CAPD/CCPD for children in Europe overall has been less spectacular, but there is wide variability from country to country, with CAPD/CCPD concentrated in eight member countries of the European Dialysis and Transplant Association. Several of these countries (notably the United Kingdom, Israel, the Netherlands and the former Federal Republic of Germany) were treating 46% to 70% of pediatric patients with CAPD/CCPD by the end of 1987. Other European countries such as France and Spain showed little growth of CAPD/CCPD over the decade (10% to 20% of patients treated with CAPD/CCPD). In Japan, CAPD for children has just begun, but because Japanese children are likely to spend longer periods on dialysis awaiting transplantation, information on long-term use of CAPD/CCPD in children may be forthcoming from Japan in the future. No effort is made to compare CAPD/CCPD to hemodialysis as a maintenance therapy for children. The advantages of CAPD/CCPD for the young patient, especially the infant and very young child are noted, and from the past decade of dramatic worldwide growth of CAPD/CCPD in pediatric patients it is inferred that the majority of children, (from 50% to 75%) can be successfully treated with these modalities, at least for the short-term (that is, several years), while awaiting transplantation.

    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. PMID:27276849

    OBJECTIVE--To determine the long term effects of relaxation therapy on 24 hour ambulatory intra-arterial blood pressure in patients with mild untreated and uncomplicated hypertension. DESIGN--Four week screening period followed by randomisation to receive either relaxation therapy or non-specific counselling for one year. Ambulatory intra-arterial blood pressure was measured before and after treatment. SETTING--Outpatient clinic in Amsterdam's university hospital. SUBJECTS--35 Subjects aged 20-60 who were being treated by general practitioners for hypertension but were referred to take part in the study. At three consecutive screening visits all subjects had a diastolic blood pressure without treatment of 95-110 mm Hg. Subjects were excluded if they had damaged target organs, secondary hypertension, diabetes mellitus, a cholesterol concentration greater than 8 mmol/l, or a history of malignant hypertension. INTERVENTIONS--The group allocated to relaxation therapy was trained for eight weeks (one hour a week) in muscle relaxation, yoga exercises, and stress management and continued exercising twice daily for one year with monthly visits to the clinic. The control group had the same attendance schedule but had no training and were requested just to sit and relax twice a day. All subjects were asked not to change their diet or physical activity. MAIN OUTCOME MEASURE--Changes in ambulatory intra-arterial blood pressure after one year of relaxation therapy or non-specific counselling. RESULTS--Mean urinary sodium excretion, serum concentration of cholesterol, and body weight did not change in either group. Diastolic pressures measured by sphygmomanometry were 2 and 3 mm Hg lower in subjects in the relaxation group and control group respectively at the one year follow up compared with initial readings. The mean diastolic ambulatory intra-arterial pressure during the daytime had not changed after one year in either group, but small treatment effects could not be excluded

    A system has been developed which permits continuous 24 hour ambulatory recording of intragastric pH under near-physiological conditions. The system utilises a Cecar combination pH electrode connected through a pre-amplifier to an Oxford Medical Systems Medilog 4-24 cassette recorder, and the pH recorded continuously on to tape. The data is replayed at high speed, digitised and then analysed. Sources of error included system drift, system noise and the effect of changes in electrode environment due to saliva, food, loss of fluid contact, temperature variations and electrode time constant. These were found to be small. In contrast, the major changes in pH detected reflect real changes at the electrode tip. These changes can be recorded by the system. Developments in electronics and improvements in both the size and quality of pH electrodes, over the past few decades, has enabled intragastric pH recordings to be made with greater ease. However, a large number of investigators still assess gastric acidity by infrequent, intermittent sampling of gastric secretion through a naso-gastric tube. This new ambulatory system is a significant improvement and its versatility allows studies in acid secretion physiology, pharmacology and pathophysiology. PMID:3595080

    Subcutaneous recombinant human erythropoietin (rHuEpo) treatment of renal anemia was performed in four boys and eight girls on CAPD, aged 0.8-12.5 (mean 7.4) years. In contrast to previous studies, our therapeutic goal was not set with a hematocrit of 30% but with full correction of anemia. Following a maximum weekly rHuEpo dosage of median 120 (range 100-240) IU/kg body weight, hematocrit increased in 10 children from 24 (14-29)% within 12 (4-17) weeks to 40.1 (33.5-48.4)%. The weekly increase in hematocrit was 1.27 (0.5-3.1)%. The corrected reticulocyte count increased from 1.3 (0.7-1.8)% to 2.3 (1.4-3.9)% within 4 (2-6) weeks. Eight children fulfilled the protocol; six with an uncomplicated course were able to maintain a hematocrit of 37.1 (35.1-42.7)% with only one sc medication per week of approximately two-thirds of their highest weekly rHuEpo dosage. No serious adverse effect of rHuEpo therapy was observed. PMID:8111178

    A transducer tipped catheter and simple recording system were used for the continuous measurement of ambulatory pulmonary artery pressure. The pulmonary artery pressure was recorded on a miniaturised tape recorder and replayed via an optical writer. Pulmonary arterial systolic and diastolic pressures can be analysed on a beat to beat basis. Continuous ambulatory monitoring was performed for a total 288 hours in 13 patients who were undergoing routine investigation for coronary artery disease. There was less than 1% zero drift and 0.25% linearity error per full scale pressure. The frequency response of the entire system was flat to 8 Hz with a linear phase delay. The transducer tipped catheter and a conventional fluid-filled system were used to measure left ventricular and pulmonary artery end diastolic pressures in eight patients. The correlation between the results obtained by the two methods was excellent. This method could be used at any centre equipped for ambulatory electrocardiographic monitoring. PMID:3964499

    Peritonitis is a serious infection and early diagnosis and treatment is mandatory. A variety of microorganisms are identified in these cases and during recent years a new one was included, Pantoea agglomerans. In this case report, a female patient on continuous ambulatory peritoneal dialysis therapy with a peritonitis episode caused by this organism is described. The source of infection was thought to be due to contact of catheter with non-sterile surfaces. In microbiologic culture, this organism was identified and the patient successfully treated with a three week course of gentamicin therapy. The number of reported cases with this organism has increased in last years and various infection localizations and clinical progress patterns have been identified. In peritoneal dialysis patients presenting with peritonitis, this organism must be kept in mind. PMID:25022305

    Objectives: The goal of this study was to identify association between the continuity of ambulatory care of diabetes patients in South Korea (hereafter Korea) and the incidence of macrovascular complications of diabetes, using claims data compiled by the National Health Insurance Services of Korea. Methods: This study was conducted retrospectively. The subjects of the study were 43 002 patients diagnosed with diabetes in 2007, who were over 30 years of age, and had insurance claim data from 2008. The macrovascular complications of diabetes mellitus were limited to ischemic heart disease and ischemic stroke. We compared the characteristics of the patients in whom macrovascular complications occurred from 2009 to 2012 to the characteristics of the patients who had no such complications. Multiple logistic regression was used to assess the effects of continuity of ambulatory care on diabetic macrovascular complications. The continuity of ambulatory diabetes care was estimated by metrics such as the medication possession ratio, the quarterly continuity of care and the number of clinics that were visited. Results: Patients with macrovascular complications showed statistically significant differences regarding sex, age, comorbidities, hypertension, dyslipidemia and continuity of ambulatory diabetes care. Visiting a lower number of clinics reduced the odds ratio for macrovascular complications of diabetes. A medication possession ratio below 80% was associated with an increased odds ratio for macrovascular complications, but this result was of borderline statistical significance. Conclusions: Diabetes care by regular health care providers was found to be associated with a lower occurrence of diabetic macrovascular complications. This result has policy implications for the Korean health care system, in which the delivery system does not work properly. PMID:26265664

    Background Many internal medicine (IM) programs have reorganized their resident continuity clinics to improve trainees' ambulatory experience. Downstream effects on continuity of care and other clinical and educational metrics are unclear. Methods This multi-institutional, cross-sectional study included 713 IM residents from 12 programs. Continuity was measured using the usual provider of care method (UPC) and the continuity for physician method (PHY). Three clinic models (traditional, block, and combination) were compared using analysis of covariance. Multivariable linear regression analysis was used to analyze the effect of practice metrics and clinic model on continuity. Results UPC, reflecting continuity from the patient perspective, was significantly different, and was highest in the block model, midrange in combination model, and lowest in the traditional model programs. PHY, reflecting continuity from the perspective of the resident provider, was significantly lower in the block model than in combination and traditional programs. Panel size, ambulatory workload, utilization, number of clinics attended in the study period, and clinic model together accounted for 62% of the variation found in UPC and 26% of the variation found in PHY. Conclusions Clinic model appeared to have a significant effect on continuity measured from both the patient and resident perspectives. Continuity requires balance between provider availability and demand for services. Optimizing this balance to maximize resident education, and the health of the population served, will require consideration of relevant local factors and priorities in addition to the clinic model.

    OBJECTIVES: To evaluate the clinical outcomes and identify the predictors of mortality in elderly patients undergoing peritoneal dialysis. METHODS: We conducted a retrospective study including all incident peritoneal dialysis cases in patients ≥65 years of age treated from 2001 to 2014. Demographic and clinical data on the initiation of peritoneal dialysis and the clinical events during the study period were collected. Infectious complications were recorded. Overall and technique survival rates were analyzed. RESULTS: Fifty-eight patients who began peritoneal dialysis during the study period were considered for analysis, and 50 of these patients were included in the final analysis. Peritoneal dialysis exchanges were performed by another person for 65% of the patients, whereas 79.9% of patients preferred to perform the peritoneal dialysis themselves. Peritonitis and catheter exit site/tunnel infection incidences were 20.4±16.3 and 24.6±17.4 patient-months, respectively. During the follow-up period, 40 patients were withdrawn from peritoneal dialysis. Causes of death included peritonitis and/or sepsis (50%) and cardiovascular events (30%). The mean patient survival time was 38.9±4.3 months, and the survival rates were 78.8%, 66.8%, 50.9% and 19.5% at 1, 2, 3 and 4 years after peritoneal dialysis initiation, respectively. Advanced age, the presence of additional diseases, increased episodes of peritonitis, the use of continuous ambulatory peritoneal dialysis, and low albumin levels and daily urine volumes (<100 ml) at the initiation of peritoneal dialysis were predictors of mortality. The mean technique survival duration was 61.7±5.2 months. The technique survival rates were 97.9%, 90.6%, 81.5% and 71% at 1, 2, 3 and 4 years, respectively. None of the factors analyzed were predictors of technique survival. CONCLUSIONS: Mortality was higher in elderly patients. Factors affecting mortality in elderly patients included advanced age, the presence of comorbid

    Background Many internal medicine programs have reorganized their resident continuity clinics to improve the ambulatory care experience for residents. The effect of this redesign on patient satisfaction is largely unknown. Methods Our multi-institutional, cross-sectional study included 569 internal medicine residents from 11 programs participating in the Educational Innovations Project Ambulatory Collaborative. An 11-item patient satisfaction survey from the Consumer Assessment of Healthcare Providers and Systems was used to assess patient satisfaction, comparing patient satisfaction in traditional models of weekly continuity clinic with 2 new clinic models. We then examined the relationship between patient satisfaction and other practice variables. Results Patient satisfaction responses related to resident listening and communication skills, knowledge of medical history, perception of adequate visit time, overall rating, and willingness to refer to family and friends were significantly better in the traditional and block continuity models than the combination model. Higher ambulatory workload was associated with reduced patient perception of respect shown by the physician. The percentage of diabetic patients with glycated hemoglobin < 8% was positively correlated with number of visits, knowledge of medical history, perception of respect, and higher scores for recommending the physician to others. The percentage of diabetic patients with low density lipoprotein < 100 mg/dL was positively correlated with the physician showing respect. Conclusions Patient satisfaction was similar in programs using block design and traditional models for continuity clinic, and both outperformed the combination model programs. There was a delicate balance between workload and patient perception of the physician showing respect. Care outcome measures for diabetic patients were associated with aspects of patient satisfaction. PMID:26279771

    Sphingomonas paucimobilis, a yellow-pigmented, aerobic, glucose non-fermenting, Gram-negative bacillus, is a rare cause of human infection normally associated with immunocompromised hosts. It has been associated with a few cases of continuous ambulatory peritoneal dialysis (PD) and is notorious for its resistance to the commonly used antibiotics. In half of the cases reported so far, the peritonitis was refractory to treatment, necessitating PD catheter removal. We report a case of Sphingomonas paucimobilis peritonitis in a 50-year-old patient who had been on PD for two years. The patient was successfully treated with intraperitoneal and intravenous antibiotics and the PD catheter was salvaged. PMID:26022030

    Most episodes of peritoneal dialysis (PD)-related peritonitis could be attributed to a single organism, but in almost 10% of peritonitis episodes multiple organisms are identified. Polymicrobial peritonitis is often related to intra-abdominal pathology, and the prognosis may be poor. Aeromonas spp. have rarely been identified as the causative pathogen in PD-related peritonitis, and a very small number of cases has been reported in the literature. These rod-shaped, gram-negative microorganisms have been isolated from wastewater drainage systems, food, vegetables, and soil. Herein we report a case of polymicrobial peritonitis in a continuous ambulatory peritoneal dialysis (CAPD) patient with systemic lupus erythematosus (SLE), due to a combination of Streptococcus viridans and Aeromonas hydrophila infection. The patient was involved in gardening and was not compliant with her technique protocol. She did not wear a mask and omitted thorough hand washing. The patient was treated with i.p. vancomycin and ceftazidime and peritonitis was resolved. The patient's technique was reassessed, and she was retrained by our PD nurses. PMID:21269597

    Numerous factors related to the composition of peritoneal dialysis solutions (PDS) contribute to the pathogenesis of peritoneal fibrosis during continuous ambulatory peritoneal dialysis (CAPD). They include high osmolarity, low pH, and the presence of lactate, which may be responsible for stimulating the proliferation of peritoneal fibroblasts (PF) and for the toxicity on the peritoneal mesothelial cells (PMC). Similar effects could be hypothesized for the plasticizers released from the PDS bags, usually made of polyvinyl chloride (PVC), such as the acid esters of phthalic acid, particularly bis-(2-ethylhexyl) phthalate (BEHP). Recently, however, new BEHP-free bags (Clear-Flex, Bieffe, Italy) made of three layers (polyethylene, nylon, and polypropylene) have been introduced. The aim of this work is to evaluate in vitro the effects of samples of PDS contained in PVC bags (Bieffe) and in Clear-Flex bags on the proliferative capacity of peritoneal fibroblasts and peritoneal mesothelial cells, and the release of interferon gamma (IFN gamma), interleukin-1 (IL-1) and prostaglandin E2 (PGE2) from peritoneal T lymphocytes (PTLs) and macrophages (PM phi s). Results have shown that in the presence of PDS samples contained in PVC bags, the proliferative capacity of peritoneal fibroblasts was higher than in Clear-Flexbags. There was also an increased release of IFN-gamma and IL-1 from PTLs and PM phi s (cytokines that stimulate the collagen synthesis) and a decreased release of PGE2 (cytokines which inhibit the collagen synthesis). An inhibiting action on peritoneal mesothelial cells was also seen.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8105908

    A case of a23 year old female with peritoneal melanosis associated with adenocarcinoma of the rectum is reported. During laparoscopic anterior resection of the rectum, diffuse black pigmentations on the parietal peritoneum, greater omentum, mesenteric lymph nodes and ovaries were discovered. The histopathological findings revealed the presence of macrophages packed with black pigment. These results together with clinical data excluded metastatic melanoma and confirmed the diagnosis of the race condition called peritoneal melanosis. Due to the begin character of the lesions the laparoscopic treatment was continued. There were no remissions or progression of the reported in English literature and this is the second case of peritoneal melanosis that has been associated with adenocarcinoma of the large intestine.

    Peritonitis is the leading complication of peritoneal dialysis, which is primarily caused by bacteria rather than fungi. Peritonitis is responsible for approximately 18% of the infection-related mortality in peritoneal dialysis patients. In this paper, we report the isolation of a rare fungus, Quambalaria cyanescens, from the peritoneal fluid of a man after he switched from continuous ambulatory peritoneal dialysis to nocturnal intermittent peritoneal dialysis. Based on the morphological examination and multigene phylogeny, the clinical isolate was confirmed as Q. cyanescens. This pathogen exhibited low sensitivity to all tested echinocandins and 5-flucytosine. Interestingly, morphological characterization revealed that Q. cyanescens UM 1095 produced different pigments at low temperatures (25°C and 30°C) on various culture media. It is important to monitor the emergence of this rare fungus as a potential human pathogen in the tropics. This study provides insight into Q. cyanescens UM 1095 phenotype profiles using a Biolog phenotypic microarray (PM). Of the 760 nutrient sources tested, Q. cyanescens UM 1095 utilized 42 compounds, and the fungus can adapt to a broad range of osmotic and acidic environments. To our knowledge, this is the first report of the isolation of Q. cyanescens from peritoneal fluid, revealing this rare fungus as a potential human pathogen that may be misidentified using conventional methods. The detailed morphological, molecular and phenotypic characterization of Q. cyanescens UM 1095 provides the basis for future studies on its biology, lifestyle, and potential pathogenicity.

    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.

    Pleural effusion secondary to pleuroperitoneal communication is an unusual complication of continuous ambulatory peritoneal dialysis. Many modalities have been used to diagnosis pleuroperitoneal: pleural fluid analysis, chest X- ray, Tc-99m gammagraphy, computed tomography scan and magnetic resonance image. Some of these procedures are invasive or have a high risk of induced-contrast nephrotoxicity. We present two case reports of pleuroperitoneal leak in two patients on peritoneal dialysis diagnosed with Tc-99m gammagraphy. We conclude that Tc- 99m gammagraphy is a simple, safe, non invasive, low radiation exposure and cost effective method in the assessment and evaluation of complications related to peritoneal dialysis such as pleuroperitoneal leak.

    Malignant bowel obstruction (MBO) is commonly seen in patients with advanced abdominal cancers. The incidence of pediatric MBO in a patient with Burkitt's lymphoma and ataxia telangiectasia is rare, with no published case reports till now. Conservative management of inoperable MBO results in relief of symptoms and improves quality of life. An 11-year-old boy with Burkitt's lymphoma and ataxia telangiectasia was referred to pediatric palliative care with MBO. The objective of this report is to demonstrate conservative management of pediatric MBO using continuous ambulatory drug delivery system. The patient was initiated on continuous ambulatory drug delivery (CADD) system for symptom relief. MBO was reversed with conservative management and the child was discharged on self-collapsible portable elastomeric continuous infusion pump under the supervision of a local family physician. The child remained comfortable at home for 4 weeks until his death. His parents were satisfied with the child's symptom control, quality of life, and were able to care for the child at home. In a resource-limited setting, managing patients at home using elastomeric continuous infusion pumps instead of expensive automated CADD is a practical pharmacoeconomic approach. PMID:26862790

  14. Dialysate leaks in peritoneal dialysis.

    Leblanc, M; Ouimet, D; Pichette, V

    2001-01-01

    Dialysate leakage represents a major noninfectious complication of peritoneal dialysis (PD). An exit-site leak refers to the appearance of any moisture around the PD catheter identified as dialysate; however, the spectrum of dialysate leaks also includes any dialysate loss from the peritoneal cavity other than via the lumen of the catheter. The incidence of dialysate leakage is somewhat more than 5% in continuous ambulatory peritoneal dialysis (CAPD) patients, but this percentage probably underestimates the number of early leaks. The incidence of hydrothorax or pleural leak as a complication of PD remains unclear. Factors identified as potentially related to dialysate leakage are those related to the technique of PD catheter insertion, the way PD is initiated, and weakness of the abdominal wall. The pediatric literature tends to favor Tenckhoff catheters over other catheters as being superior with respect to dialysate leakage, but no consensus on catheter choice exists for adults in this regard. An association has been found between early leaks (< or =30 days) and immediate CAPD initiation and perhaps median catheter insertion. Risk factors contributing to abdominal weakness appear to predispose mostly to late leaks; one or more of them can generally be identified in the majority of patients. Early leakage most often manifests as a pericatheter leak. Late leaks may present more subtly with subcutaneous swelling and edema, weight gain, peripheral or genital edema, and apparent ultrafiltration failure. Dyspnea is the first clinical clue to the diagnosis of a pleural leak. Late leaks tend to develop during the first year of CAPD. The most widely used approach to determine the exact site of the leakage is with computed tomography after infusion of 2 L of dialysis fluid containing radiocontrast material. Treatments for dialysate leaks include surgical repair, temporary transfer to hemodialysis, lower dialysate volumes, and PD with a cycler. Recent recommendation propose

    A 9-year-old boy with end-stage renal disease who was receiving continuous ambulatory peritoneal dialysis (CAPD) presented with acute visual loss and was found to have papilledema. Neuroimaging and cerebrospinal fluid (CSF) analysis were normal. The lumbar puncture opening pressure was 290 mm of water so the diagnosis of pseudotumor cerebri (PTC) was entertained. Medical treatment was not an option because of renal insufficiency; neither was lumbo-peritoneal shunting, because of the peritoneal dialysis. After a lumbo-pleural shunt was placed, there was marked improvement in symptoms. The lumbo-pleural shunt is a reasonable option for treatment for PTC in patients on CAPD who require a CSF divergence procedure. PMID:21911996

    The proportion of end-stage renal disease (ESRD) patients on peritoneal dialysis (PD) has increased very fast in China over the last decade. Renji Hospital, affiliated with Shanghai Jiaotong University School of Medicine, is a recognized high-quality PD unit with a high PD utilization rate, excellent patient and technique survival (1-year and 5-year patient survival rate of 93% and 71%, and 1-year and 5-year technique survival of 96% and 82%, respectively), low peritonitis rate and a well-documented good quality of life of the treated patients. We believe that a dedicated and experienced PD team, a structured patient training program, continuous patient support, establishing and utilizing standardized protocols, starting PD with low dialysis dose, monitoring key performance indicators (KPIs), and continuous quality improvement (CQI) are the key factors underlying this successful PD program.

    This study describes experiments that compare the proteoglycans (PGs) extracted from the dialysate from patients receiving continuous peritoneal ambulatory dialysis (CAPD) with those secreted by metabolically labeled human peritoneal mesothelial cells in vitro. The PGs isolated from both sources were predominantly small chondroitin sulfate/dermatan sulfate PGs. Western blot of the core proteins obtained after chondroitin ABC lyase treatment with specific antibodies identified decorin and biglycan. With [35S]sulfate and [35S]methionine as labeling precursors it was shown that dermatan sulfate rather than chondroitin sulfate were the major glycosaminoglycan chains and that decorin was the predominant species. These data provide the first evidence that human peritoneal mesothelial cells may be the principal source of PGs in the peritoneum. Given the proposed functions of decorin and biglycan, the results suggest that these PGs may be involved in the control of transforming growth factor-beta activity and collagen fibril formation in the peritoneum.

    The pharmacokinetics of piperacillin given intravenously (1 or 2 g) to nine patients with chronic renal failure and undergoing continuous ambulatory peritoneal dialysis was intermediate between values obtained in healthy volunteers and in patients with renal insufficiency studied between dialyses: half-life, 2.4 h; total clearance, 100 mL/min; urinary or peritoneal clearance, 3 mL/min. The intraperitoneal administration of piperacillin in dialysis fluid (400 mg or 1 g to five patients) increased the half-life (6 to 7 h) and decreased the volume of distribution of about two thirds. In both instances, the area under the curve was well correlated with dosage. The absorption of piperacillin by an inflamed peritoneum in eight patients suffering from peritonitis and treated with 400 mg, 1 g, or 2 g, was increased and returned to normal concurrently with care. Consequently, the recommended dosage is intravenous administration of 2 g of piperacillin every 8 h or intraperitoneal administration of 1 g every 6 h in the dialysate. With such conditions, serum concentrations greater than minimal inhibitory concentrations and sufficient to avoid dissemination of piperacillin-susceptible organisms without risk of accumulation are obtained.

  20. Peritoneal dialysis: from bench to bedside

    PubMed Central

    2013-01-01

    Peritoneal dialysis was first employed in patients with acute renal failure in the 1940s and since the 1960s for those with end-stage renal disease. Its popularity increased enormously after the introduction of continuous ambulatory peritoneal dialysis in the end of 1970s. This stimulated both clinical and basic research. In an ideal situation, this should lead to cross-fertilization between the two. The present review describes two examples of interactions: one where it worked out very well and another where basic science missed the link with clinical findings. Those on fluid transport are examples of how old physiological findings on absorption of saline and glucose solutions were adopted in peritoneal dialysis by the use of glucose as an osmotic agent. The mechanism behind this in patients was first solved mathematically by the assumption of ultrasmall intracellular pores allowing water transport only. At the same time, basic science discovered the water channel aquaporin-1 (AQP-1), and a few years later, studies in transgenic mice confirmed that AQP-1 was the ultrasmall pore. In clinical medicine, this led to its assessment in patients and the notion of its impairment. Drugs for treatment have been developed. Research on biocompatibility is not a success story. Basic science has focussed on dialysis solutions with a low pH and lactate, and effects of glucose degradation products, although the first is irrelevant in patients and effects of continuous exposure to high glucose concentrations were largely neglected. Industry believed the bench more than the bedside, resulting in ‘biocompatible’ dialysis solutions. These solutions have some beneficial effects, but are evidently not the final answer.

    Ambulatory assessment (AA) covers a wide range of assessment methods to study people in their natural environment, including self-report, observational, and biological/physiological/behavioral. AA methods minimize retrospective biases while gathering ecologically valid data from patients’ everyday life in real time or near real time. Here, we report on the major characteristics of AA, and we provide examples of applications of AA in clinical psychology (a) to investigate mechanisms and dynamics of symptoms, (b) to predict the future recurrence or onset of symptoms, (c) to monitor treatment effects, (d) to predict treatment success, (e) to prevent relapse, and (f) as interventions. In addition, we present and discuss the most pressing and compelling future AA applications: technological developments (the smartphone), improved ecological validity of laboratory results by combined lab-field studies, and investigating gene-environment interactions. We conclude with a discussion of acceptability, compliance, privacy, and ethical issues. PMID:23157450

    The purpose of the study was to evaluate whether there is a difference between blood pressure measured in a physician's office and the average 24 hr continuous blood pressure monitored by hypertensive patients at home. If there is a difference between these two situations then is it possibly the result of a blood pressure response by the patient to the physician which is known as "white coat effect" or "white coat hypertension". We studied 80 hypertensive outpatients which were divided into two groups of 40 patients each--a younger patient group, with a mean age of 22.8 +/- 1.8 years, and an older patient group with a mean age of 50.3 +/- 5.7 years. They were selected because they had been diagnosed as essentially hypertension grade 1, according to 2007 ESH/ESC Guidelines, or the USA Joint National Committee Guidelines (JNC 7) (i.e., arterial blood pressure > 140/90 mm Hg and < 160/100 mmHg) and 35 were not having any antihypertensive treatment. All participants in the study went through a two-week "wash-out" period without medication. At the beginning of the study blood pressure was measured using the Riva-Rocci-Korotkoff method (mercury sphygmomanometer) after 5 minutes of rest and with the patient in the sitting position. The average of the two last measurements by sphygmomanometer was used in the analysis. The subsequent measurement was made by continuous ambulatory blood pressure monitoring (SpaceLabs 90207 device). Continuous ambulatory blood pressure monitoring revealed that 17 patients of the younger age group (42.5%) who were diagnosed hypertonic, according to mercury sphygmomanometeric measurement, were in fact normotonic. In the older age group only 7 (17.5%) of participants were normotonic during 24 hr blood pressure monitoring. The proportion of miss-diagnosed normotonic younger patients was directly related to elevated clinic blood pressure, which could be referred to as office hypertension or isolated clinic hypertension (white coat hypertension

    Background and aim: The physiological mechanisms regulating zinc homeostasis in humans have been elucidated and described, but the knowledge of zinc status and zinc distribution in the tissues and in the different biological compartments of patients with conservatively treated chronic renal failure (CRF) and on peritoneal dialysis is still insufficient. This investigation examines and compares zinc content in urine, erythrocytes, plasma, and outflow dialysis solution in a group of continuous ambulatory peritoneal dialysis (CAPD) patients, a group of patients with CRF on conservative treatment and in healthy controls. Material and Methods: Data from the last 6 months of 22 adult hemodialysis patients with a mean age of 61 ± 14 years were analyzed retrospectively. Dialysis vintage, normalized protein catabolic rate (nPCR), serum biochemical parameters, mid arm muscle circumference (MAMC) were determined as mean and standard deviation. Correlations between the variables were computed by coefficient p of Pearson. Results and conclusion: In patients on CAPD treatment (group 3) compared to healthy controls (group 1) plasma zinc level was diminished (р<0.05), while erythrocyte zinc elevated (р<0.01). The investigation found out difference between plasma, erythrocyte and urine levels of zinc between the patients with chronic renal failure (group 2) on conservative treatment and those treated by CAPD (group 3), which proves, that continuous ambulatory peritoneal dialysis influences redistribution of zinc in human organism "per se".

    Background We aimed to determine with this randomized, triple-masked, placebo-controlled study if benefits are afforded by adding a multiple-day, ambulatory, continuous ropivacaine paravertebral nerve block to a single-injection ropivacaine paravertebral block following mastectomy. Methods Preoperatively, 60 subjects undergoing unilateral (n = 24) or bilateral (n = 36) mastectomy received either unilateral or bilateral paravertebral perineural catheter(s), respectively, inserted between the third and fourth thoracic transverse process(es). All subjects received an initial bolus of ropivacaine 0.5% (15 mL) via the catheter(s). Subjects were randomized to receive either perineural ropivacaine 0.4% or normal saline using portable infusion pump(s) [5 mL/h basal; 300 mL reservoir(s)]. Subjects remained hospitalized for at least 1 night and were subsequently discharged home where the catheter(s) were removed on postoperative day 3. Subjects were contacted by telephone on postoperative days 1, 4, 8, and 28. The primary end point was average pain (scale: 0–10) queried on postoperative day (POD) 1. Results Average pain queried on POD 1 for subjects receiving perineural ropivacaine (n=30) was a median (interquartile) of 2 (0–3), compared with 4 (1–5) for subjects receiving saline (n = 30; 95% CI difference in medians, −4.0 – −0.3; P = 0.021]. During this same time period, subjects receiving ropivacaine experienced a lower severity of breakthrough pain (5 [3–6] vs 7 [5–8]; P = 0.046) as well. As a result, subjects receiving perineural ropivacaine experienced less pain-induced physical and emotional dysfunction, as measured with the Brief Pain Inventory (lower score = less dysfunction): 14 (4–37) vs 57 (8–67) for subjects receiving perineural saline (P = 0.012). For the subscale that measures the degree of interference of pain on 7 domains, such as general activity and relationships, subjects receiving perineural saline reported a median score 10 times

    In the developing countries it is not possible to determine the total amount of money spent in the treatment of chronic diseases, and the practice of renal replacement therapies faces many obstacles. In Mexico, the introduction of continuous ambulatory peritoneal dialysis and continuous cycling peritoneal dialysis (CCPD) achieved very good results. Unfortunately, renal disease still affected as much as 95% of chronic renal failure patients and it became a disaster with an annual mortality rate higher than 60%. This was known as the Mexican Model which failed in establishing peritoneal dialysis as the only procedure for treating patients. In order to avoid a similar scenario with the 2 replacement therapies, we created the Official Norm for hemodialysis, and now we are experimenting with an increase from 5% to 20% of hemodialysis patients who are receiving therapy, principally in private units that attend Social Security patients. In addition, the government has established a Council for Transplantation that acts as a regulatory board. In other words, we are in the process of making chronic renal diseases a priority within the National Program. PMID:12197926

    ♦ Background: To understand how peritoneal dialysis (PD) was being used in Italy in 2005 and 2008, a census of all centers was carried out. ♦ Methods: In 2005 and 2008, data were collected from, respectively, 222 and 223 centers, with respect to 4432 and 4094 prevalent patients. ♦ Results: In the two periods, the PD incidence remained stable (24.3% vs 22.9%), varying from center to center. Continuous ambulatory PD (CAPD) was the main initial method (55%), but APD was more widespread among prevalent patients (53%). Among patients returning to dialysis from transplantation (Tx), PD was used in 10%. The use of incremental CAPD increased significantly from 2005 to 2008, in terms both of the number of centers (27.0% vs 40.9%) and of patients (13.6% vs 25.7%). Late referrals remained stable at 28%, with less use of PD. The overall drop-out rate (episodes/100 patient-years) remained unchanged (31.0 vs 32.8), with 13.1 and 12.9 being the result of death, and 11.8 and 12.4 being the result of a switch to hemodialysis, mainly after peritonitis. A dialysis partner was required by 21.8% of the PD patients. The incidence of peritonitis was 1 episode in 36.5 and 41.1 patient-months, with negative cultures occurring in 17.1% of cases in both periods. The incidence of encapsulating peritoneal sclerosis (episodes/100 patient-years) was 0.70, representing 1.26% of patients treated. The catheter types used and the sites and methods of insertion varied widely from center to center. ♦ Conclusions: These censuses confirm the good results of PD in Italy, and provide insight into little-known aspects such as the use of incremental PD, the presence of a dialysis partner, and the incidence of encapsulating peritoneal sclerosis.

    PORTAPRES model 1 is a portable 24 h continuous noninvasive blood pressure recorder based on the same principles as FINAPRES, the volume-clamp method of Peñaz and the physiocal criteria of Wesseling. In addition, PORTAPRES measures two adjacent fingers in alternation every 30 min and automatically corrects hydrostatic effects due to height changes of the measured fingers. The device measures 255 x 210 x 60 mm and weights about 3,000 g, including a lithium battery pack and a TEAC cassette FM instrumentation tape recorder to record the finger pressure wave form, the height signal, and beat-to-beat derived systolic, mean and diastolic pressure as well as heart rate. It appears to be an excellent new tool for cardiovascular research in humans. In a randomized, placebo-controlled, double-blind, crossover study the effect of oral administration of 2.5 mg cilazapril, a new potent long-acting, nonsulfhydryl-group angiotensin converting enzyme (ACE) inhibitor, given once daily for 7 days, was investigated in 16 healthy young men (mean age 25.3 +/- 1.6 years). Finger blood pressure and heart rate were measured with PORTAPRES for 24 h during everyday life and during standardized laboratory tasks, once about 1 to 2 h A.M. and once about 10 to 11 h P.M. once about 1 to 2 h A.M. and once about 10 to 11 h P.M. after drug administration. Physical activity was controlled by integrated thigh-EMG. Using stepwise multiple linear regression analysis it was shown that based on 64 s mean values, this measure of physical activity explains 34-77% of the heart rate variance within 24 h (median 53%), 10-52% (31%) of systolic, and 4-38% (25%) of diastolic blood pressure variance when up to 20 time lags of the EMG signal were introduced as possible predictors. This indicates that varying degrees of physical activity have a great impact on everyday blood pressure and heart rate. After one week cilazapril did not alter 24-h means of systolic and diastolic blood pressure or heart rate

    Background and objectives Vital signs are usually recorded at 4–8 h intervals in hospital patients, and deterioration between measurements can have serious consequences. The primary study objective was to assess agreement between a new ultra-low power, wireless and wearable surveillance system for continuous ambulatory monitoring of vital signs and a widely used clinical vital signs monitor. The secondary objective was to examine the system's ability to automatically identify and reject invalid physiological data. Setting Single hospital centre. Participants Heart and respiratory rate were recorded over 2 h in 20 patients undergoing elective surgery and a second group of 41 patients with comorbid conditions, in the general ward. Outcome measures Primary outcome measures were limits of agreement and bias. The secondary outcome measure was proportion of data rejected. Results The digital patch provided reliable heart rate values in the majority of patients (about 80%) with normal sinus rhythm, and in the presence of abnormal ECG recordings (excluding aperiodic arrhythmias such as atrial fibrillation). The mean difference between systems was less than ±1 bpm in all patient groups studied. Although respiratory data were more frequently rejected as invalid because of the high sensitivity of impedance pneumography to motion artefacts, valid rates were reported for 50% of recordings with a mean difference of less than ±1 brpm compared with the bedside monitor. Correlation between systems was statistically significant (p<0.0001) for heart and respiratory rate, apart from respiratory rate in patients with atrial fibrillation (p=0.02).

    Although skin-to-skin contact (or kangaroo mother care, KMC) for preterm infants is a practical alternative to incubator care, no studies have compared these methods using continuous ambulatory temperature monitoring. To compare thermal regulation in low birthweight infants (< 2000 g) managed by KMC alternating with conventional care (CC) and to determine the acceptability to mothers of KMC, an experimental study with a crossover design with observational and qualitative data collected on temperature patterns and mothers attitudes to skin-to-skin care was conducted in the neonatal wards of three hospitals in Lagos, Nigeria. Thirteen eligible infants were nursed by their mothers or surrogates in 38 4-hour sessions of KMC and the results compared with 38 sessions of incubator care. The risk of hypothermia was reduced by > 90% when nursed by KMC rather than conventional care, relative risk (RR) 0.09 (0.03-0.25). More cases of hyperthermia (> 37.5 degrees C) occurred with KMC, and coreperiphery temperature differences were widened, but the risk of hyperthermia > 37.9 degrees C (RR 1.3, 0.9-1.7) was not significant. Micro-ambient temperatures were higher during KMC, although the average room temperatures during both procedures did not differ significantly. Mothers felt that KMC was safe, and preferred the method to CC because it did not separate them from their infants, although some had problems adjusting to this method of care. Where equipment for thermal regulation is lacking or unreliable, KMC is a preferable method for managing stable low birthweight infants. PMID:15479575

    This study compared the static and kinetic activities, in both broth and used-dialysate, of selected antibiotics against 23 strains of coagulase-negative staphylococci causing peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD). Vancomycin was shown to be effective against all isolates with similar rates of kill to flucloxacillin and cefuroxime, although a few strains were found to be resistant to cefuroxime. Gentamicin was rapidly bactericidal for sensitive strains which accounted for 60% of the strains tested. Fusidic acid was associated with significant resistance and lack of bactericidal activity in the kinetic studies. Emergence of resistance occurred with rifampicin. The combinations clavulanic acid/amoxycillin and sulbactam/ampicillin generally showed good static activity. In addition a broad range of biotypes and phage types were demonstrated among these organisms with biotype SII (Staphylococcus epidermidis) predominating. There was no correlation between biotype and antibiogram. PMID:3997705

    Chronic peritoneal dialysis (PD), especially continuous ambulatory PD (CAPD), is being increasingly utilized in South Asian countries (population of 1.4 billion). There are divergent geopolitical and socioeconomic factors that influence the growth and expansion of CAPD in this region. The majority of the countries in South Asia are lacking in government healthcare system for reimbursing renal replacement therapy. The largest utilization of chronic PD is in India, with nearly 6500 patients on this treatment by the end of 2006. A large majority of patients are doing 2 L exchanges 3 times per day, using glucose-based dialysis solution manufactured in India. Chronic PD is not being utilized in Myanmar, Bhutan, or Seychelles. Affirmative action by the manufacturing industry, medical professionals, government policy makers, and nongovernmental organizations for reducing the cost of chronic PD will enable the growth and utilization of this life-saving therapy.

    Peritoneal dialysis is becoming more important in the management of patients with end-stage renal disease. Because of the efforts of the "Fistula First Breakthrough Initiative," dialysis venous access in the United States has become focused on promoting arteriovenous fistula creation and reducing the number of patients who start dialysis with a tunneled catheter. This is important because tunneled catheters can lead to infection, endocarditis, and early loss of more long-term access. When planned for, peritoneal dialysis can offer patients the opportunity to start dialysis at home without jeopardizing central access or the possibilities of eventual arteriovenous fistula creation. The purpose of this review is to highlight the indications, contraindications, and procedural methods for implanting peritoneal dialysis catheters in the interventional radiology suite.

    A major complication in continuous, ambulatory peritoneal dialysis in patients with end-stage renal disease who are undergoing long-term peritoneal dialysis (PD) is peritoneal fibrosis, which can result in peritoneal structural changes and functional ultrafiltration failure. Human umbilical mesenchymal stem cells (HUMSCs) in Wharton's jelly possess stem cell properties and are easily obtained and processed. This study focuses on the effects of HUMSCs on peritoneal fibrosis in in vitro and in vivo experiments. After 24-hour treatment with mixture of Dulbecco's modified Eagle's medium and PD solution at a 1:3 ratio, primary human peritoneal mesothelial cells became susceptible to PD-induced cell death. Such cytotoxic effects were prevented by coculturing with primary HUMSCs. In a rat model, intraperitoneal injections of 20 mM methylglyoxal (MGO) in PD solution for 3 weeks (the PD/MGO 3W group) markedly induced abdominal cocoon formation, peritoneal thickening, and collagen accumulation. Immunohistochemical analyses indicated neoangiogenesis and significant increase in the numbers of ED-1- and α-smooth muscle actin (α-SMA)-positive cells in the thickened peritoneum in the PD/MGO 3W group, suggesting that PD/MGO induced an inflammatory response. Furthermore, PD/MGO treatment for 3 weeks caused functional impairments in the peritoneal membrane. However, in comparison with the PD/MGO group, intraperitoneal administration of HUMSCs into the rats significantly ameliorated the PD/MGO-induced abdominal cocoon formation, peritoneal fibrosis, inflammation, neoangiogenesis, and ultrafiltration failure. After 3 weeks of transplantation, surviving HUMSCs were found in the peritoneum in the HUMSC-grafted rats. Thus, xenografts of HUMSCs might provide a potential therapeutic strategy in the prevention of peritoneal fibrosis. Significance: This study demonstrated that direct intraperitoneal transplantation of human umbilical mesenchymal stem cells into the rat effectively

    Hydrothorax secondary to trans-diaphragmatic fluid leakage through a peritoneo-pleural communication is an occasional, potentially serious complication of peritoneal dialysis. The etiology of this condition is not clear, being thought to be due either to congenital or acquired diaphragmatic fenestrations or acquired scarcity of muscle fibers in the tendinous part of the diaphragm which are compounded by increased intra-abdominal pressure during the dwell period of peritoneal dialysis. We report a 54-year-old woman who developed irreversible acute renal failure from adjuvant chemotherapy for ovarian cancer previously resected surgically. Three days after the onset of continuous ambulatory peritoneal dialysis, she developed acute respiratory distress associated with a massive right hydrothorax secondary to a peritoneo-pleural communication demonstrated by scintigraphy. At autopsy 2 weeks later, systemic amyloidosis was surprisingly found and histologic examination of the right hemidiaphragm showed the presence of amyloid, among sparse muscle fibers. This is the first case report of a distinct pathological process, i.e. amyloidosis, involving the diaphragm associated with a peritoneo-pleural communication causing massive hydrothorax at the onset of peritoneal dialysis.

    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.

    Secondary peritoneal echinococcosis was recorded from 50 in 312 patients (16 per cent) who had been hospitalised for liver echinococcosis. Hydatido and peritoneal hydatidiosis were recorded from 34 of these patients and thus accounted for the two most common pathological forms of secondary peritoneal echinococcosis, according to Dévè. Peritoneal echinococcosis usually is not diagnosed until conspicuous symptoms grow manifest due to cyst growth or other complications. Positive responses were recorded from all the above cases to laboratory tests (eosinophilia in over five to nine per cent) and were also established on the basis of immune reactions, including the complement fixation reaction according to Weinberg, the intracutaneous test by Casoni, and latex echinococcus reaction. Surgery, at present, is the only promising therapeutic approach to the problem. Surgical intervention could not even be avoided by application of mebendazol. Postoperative lethality amounted to four per cent and morbidity to ten per cent. They were comparatively low, measured by the generally poor prognosis of the disease. PMID:3776378

    The key to achieving adequate continuous ambulatory peritoneal dialysis (CAPD) is that a functioning catheter should enable unrestricted inflow and outflow of the dialysate liquid from the peritoneal cavity with an intact peritoneal membrane. Despite its advantages, complications, such as outflow obstruction, catheter-related infection, and dialysate leakage are still problematic. Various laparoscopic techniques for catheter placement have been investigated. The main purpose of this study was to compare the laparoscopic and open surgical peritoneal dialysis (PD) catheter insertion techniques in a retrospective manner according to catheter survival, complications and the safety of both techniques. The study included end stage renal disease patients in our hospital in whom a PD catheter was placed between 2007 and 2014. Patients were divided into two groups: the open technique (OT) group and the laparoscopic preperitoneal tunneling approach (LA) group. Extracted data included patient demographics, operative data, catheter-related complications and follow-up data. Sixty-nine patients were enrolled into the study. CAPD catheters were placed into 35 patients via LA and 34 via OT. We found that the LA group patients had better survival rates compared with the OT group, especially the long-term survivals. All of the CAPD-related complications, (peritonitis, malposition, outflow obstruction, leakage) were lower in the LA group. However, the peritonitis, malposition and groin hernia rates were also statistically significantly lower in the LA group. When compared with the published data, we recommend laparoscopic CAPD catheter placement with a preperitoneal tunneling technique. The technique is safe and offers a better outcome. PMID:26638124

    Patients undergoing continuous ambulatory peritoneal dialysis are classified according to their peritoneal permeability as low transporter (low solute permeability) or High transporter (high solute permeability). Factors that determine the differences in permeability between them have not been fully disclosed. We investigated morphological features of cultured human peritoneal mesothelial cells from low or high transporter patients and its response to All trans retinoic Acid (ATRA, vitamin A active metabolite), as compared to non-uremic human peritoneal mesothelial cells. Control cells were isolated from human omentum. High or low transporter cells were obtained from dialysis effluents. Cells were cultured in media containing ATRA (0, 50, 100 or 200 nM). We studied length and distribution of microvilli and cilia (scanning electron microscopy), epithelial (cytokeratin, claudin-1, ZO-1 and occludin) and mesenchymal (vimentin and α-smooth muscle actin) transition markers by immunofluorescence and Western blot, and transforming growth factor β1 expression by Western blot. Low and high transporter exhibited hypertrophic cells, reduction in claudin-1, occludin and ZO-1 expression, cytokeratin and vimentin disorganization and positive α-smooth muscle actin label. Vimentin, α-smooth muscle actin and transforming growth factor- β1 were overexpressed in low transporter. Ciliated cells were diminished in low and high transporters. Microvilli number and length were severely reduced in high transporter. ATRA reduced hypertrophic cells number in low transporter. It also improved cytokeratin and vimentin organization, decreased vimentin and α-smooth muscle actin expression, and increased claudin 1, occludin and ZO-1 expression, in low and high transporter. In low transporter, ATRA reduced transforming growth factor-β1 expression. ATRA augmented percentage of ciliated cells in low and high transporter. It also augmented cilia length in high transporter.

  4. Role of surfactant in peritoneal dialysis.

    Evidence is reviewed that demonstrates how the mesothelial cell in the normal peritoneum and comparable serosal cavities secretes surface-active phospholipid (SAPL) as a means of protecting itself and the membrane it forms with its neighbors. It is shown how SAPL, if adsorbed (reversibly bound) to mesothelium, can impart excellent lubricity, antiwear and release (antistick) properties, while impeding surgical adhesion formation. More-speculative benefits include acting as a deterrent to fibrosis and as a barrier to both protein leakage and pathogen invasion by spanning cell junctions. Such spanning would also "pin down" cell corners, impeding peeling as the first step in exfoliation encountered in prolonged continuous ambulatory peritoneal dialysis (CAPD). The molecular mechanism underlying each of these possible functions is adsorption. Morphological and hydrophobicity studies are discussed as validation for such an adsorbed lining and how it can be fortified by administering exogenous SAPL. Any role for SAPL in ultrafiltration is much more controversial. However, a surfactant lining can explain the very high permeability of the membrane to lipid-soluble drugs, implying that it is a barrier to water-soluble solutes. The clinical and animal evidence is conflicting but would seem to be best explained by a role for the barrier in promoting semipermeability, and hence the osmotic driving force for water transmission. Thus, adsorption of exogenous SAPL in CAPD patients with low ultrafiltration seems to restore this barrier function. The future direction for surfactant in CAPD would seem to rest with the physical chemists in producing formulations that optimize adsorption, probably involving a compromise between water solubility and surface activity of the phospholipids selected. It might even warrant using the interdialytic interval for readsorbing SAPL without the problem of dilution by a large volume of dialysate. PMID:11117241

    Peritoneal dialysis is a form of renal replacement alternative to the hemodialysis. During this treatment, the peritoneal membrane acts as a permeable barrier for exchange of solutes and water. Continual exposure to dialysis solutions, as well as episodes of peritonitis and hemoperitoneum, can cause acute/chronic inflammation and injury to the peritoneal membrane, which undergoes progressive fibrosis, angiogenesis, and vasculopathy, eventually leading to discontinuation of the peritoneal dialysis. Among the different events controlling this pathological process, epithelial to mesenchymal transition of mesothelial cells plays a main role in the induction of fibrosis and in subsequent functional deterioration of the peritoneal membrane. Here, the main extracellular inducers and cellular players are described. Moreover, signaling pathways acting during this process are elucidated, with emphasis on signals delivered by TGF-β family members and by Toll-like/IL-1β receptors. The understanding of molecular mechanisms underlying fibrosis of the peritoneal membrane has both a basic and a translational relevance, since it may be useful for setup of therapies aimed at counteracting the deterioration as well as restoring the homeostasis of the peritoneal membrane.

The experiment is the Autogenic Feedback Training Experiment (AFTE) scheduled for Spacelab 3, currently scheduled to be launched in November, 1984. The objectives of the AFTE are to determine the effectiveness of autogenic feedback in preventing or reducing space adaptation syndrome (SAS), to monitor and record in-flight data from the crew, to determine if prediction criteria for SAS can be established, and, finally, to develop an ambulatory instrument package to mount the crew throughout the mission. The purpose of the Ambulatory Feedback System (AFS) is to record the responses of the subject during a provocative event in space and provide a real-time feedback display to reinforce the training.

The American Academy of Ambulatory Care Nursing and the Collaborative Alliance for Nursing Outcomes propose nurse leaders create a tipping point to measure the value of nursing across the continuum of nursing care, moving from inpatient to ambulatory care. As care continues to shift into the ambulatory care environment, the quality imperative must also shift to assure highly reliable, safe, and effective health care. PMID:27439252

    Background: Attention-deficit/hyperactivity disorder (ADHD) is the most common childhood psychiatric disorder. This disorder is more prevalent in some chronic disease. Objectives: The aim of this study was to investigate ADHD in children with end-stage renal disease (ESRD) undergoing continuous ambulatory peritoneal dialysis (CAPD) and to compare the results with those of healthy children. Patients and Methods: This case-control study was conducted for six months (December 22, 2013 to June 21, 2014) on five to 16-year-old children, visiting the Pediatric Dialysis Unit of Amirkabir Hospital, Arak, Iran, and Taleghani Hospital, Kermanshah, Iran. A total of 100 children with ESRD who had undergone CAPD for at least six months and 100 healthy children were included in this study as case and control groups, respectively. ADHD was diagnosed by Conner's Parent Rating Scale-48 (CPRS-48) and DSM-IV-TR criteria, and was confirmed through consultation by psychologist. Data were analyzed by Binomial test in SPSS 18. Results: The ADHD inattentive type was observed in 16 cases (16%) with CAPD and five controls (5%) (P = 0.01). Moreover, ADHD hyperactive-impulsive type was observed in 27 cases (27%) with CAPD and seven controls (9%) (P = 0.002). Despite these significant differences, no children were diagnosed with ADHD combined type among all subjects. Conclusions: Inattentive type and hyperactive-impulsive type of ADHD are more prevalent in children with ESRD undergoing CAPD. Therefore screening methods for ADHD is necessary in these patients.

    Hyperglycemia, hypoglycemia, and glycemic variability have been associated with increased morbidity, mortality, length of stay, and cost in a variety of critical care and non-critical care patient populations in the hospital. The results from prospective randomized clinical trials designed to determine the risks and benefits of intensive insulin therapy and tight glycemic control have been confusing; and at times conflicting. The limitations of point-of-care blood glucose (BG) monitoring in the hospital highlight the great clinical need for an automated real-time continuous glucose monitoring system (CGMS) that can accurately measure the concentration of glucose every few minutes. Automation and standardization of the glucose measurement process have the potential to significantly improve BG control, clinical outcome, safety and cost. PMID:26078254

    Left ventricular hypertrophy (LVH) prevalence is very high in end stage renal disease (ESRD). It's a predictor of cardiac death in peritoneal dialysis patients. Noradrenalin, Angiotensin II and aldosterone are involved incardiac hypertrophy. Dopamine, acting at DA2 receptors inhibits norephinephrin release, antagonizes aldosterone and down-regulates AT1 receptor numbers, suggesting that DA2 agonists, like bromocriptine (BEC) could regress LVH. The objective of this study was to evaluate the changes in left ventricular mass in patients with ESRD in continuous ambulatory peritoneal dialysis (CAPD), by adding BEC to the treatment. An open clinical trial was conducted. Twenty patients were enrolled. Five formed the control group. Fifteen patients in the experimental group received BEC 2.5 mg three times daily over three months. M mode echocardiography and prolactin plasma levels were measured at the beginning and at the end of the study. The statistical analysis was performed using Student t test. The echocardiography reports showed a 24.4% decreased in left ventricular mass index (LVMI); the interventricular septum decreased 11.3%, the ejection fraction was not modified. The control group showed no difference. BEC-mediated decreases in left-ventricular mass in LVH patients on dialysis suggest that Dopaminergic agonists could be useful in caring for patients with ESRD and LVH. PMID:16416676

    three years from the straight-line systems with or without germicidal connection devices to the disconnect systems. In China and India, where PD has been introduced only recently, the disconnect systems are used almost exclusively. The disconnect systems are also the most popular systems in use in Japan and Taiwan. As data concerning the cost-effectiveness of different PD systems becomes available, it is likely that trend towards a more liberal use of disconnect systems will continue in the future. The usage of low calcium peritoneal dialysate and the average number of daily CAPD exchanges also vary among the Asian countries. Low calcium peritoneal dialysate has been introduced only in Japan, Hong Kong, and Singapore, with the highest utilization rate (90%) recorded in Singapore. The Philippines had the lowest average number of daily peritoneal exchanges (6L) among the countries surveyed, followed by Hong Kong (6.4L), China and Indonesia (7L), and the rest (8L). The use of a lower number of exchanges was introduced in some countries, initially, mainly as a cost-saving measure based on the assumption that Asians are of small body build. The justification for the continued use of a lower number of exchanges among Asian patients is debatable, but is supported by the acceptable, long-term clinical outcome of patients given this form of dialysis prescription. It is suggested that long-term prospective studies on dialysis adequacy and clinical outcome should be done in different ethnic groups in Asia to see if the similar guidelines with regard to dialysis adequacy can be applied uniformly to Orientals and Caucasians.

    Ambulatory Holter electrocardiographic (ECG) monitoring has undergone continuous technological evolution since its invention and development in the 1950s era. With commercial introduction in 1963, there has been an evolution of Holter recorders from 1 channel to 12 channel recorders with increasingly smaller storage media, and there has evolved Holter analysis systems employing increasingly technologically advanced electronics providing a myriad of data displays. This evolution of smaller physical instruments with increasing technological capacity has characterized the development of electronics over the past 50 years. Currently the technology has been focused upon the conventional continuous 24 to 48 hour ambulatory ECG examination, and conventional extended ambulatory monitoring strategies for infrequent to rare arrhythmic events. However, the emergence of the Internet, Wi-Fi, cellular networks, and broad-band transmission has positioned these modalities at the doorway of the digital world. This has led to an adoption of more cost-effective strategies to these conventional methods of performing the examination. As a result, the emergence of the mobile smartphone coupled with this digital capacity is leading to the recent development of Holter smartphone applications. The potential of point-of-care applications utilizing the Holter smartphone and a vast array of new non-invasive sensors is evident in the not too distant future. The Holter smartphone is anticipated to contribute significantly in the future to the field of global health. PMID:24215744

    Plasma cholesterol metabolism was investigated in normotriglyceridemic patients with end-stage renal disease treated by hemo- or continuous ambulatory peritoneal dialysis (CAPD), and compared with that in a control group with normal renal function. A reversed net transport of free cholesterol from plasma to cultured fibroblasts, as well as greatly reduced levels of plasma cholesterol esterification and cholesterol ester transfer rates to low and very low density lipoproteins (LDL and VLDL), was found in the hemodialysis group compared to the controls. The LDL and VLDL contained increased amounts of free cholesterol and inhibited cholesterol ester transfer when recombined with control plasma. The LDL triglyceride content was doubled in the hemodialysis group, whereas cholesterol esters were decreased. Patients treated by CAPD, in marked contrast, had cholesterol metabolic rates that were within the normal range, as well as normal lipoprotein composition. PMID:3082933

    Although highly successful as transcutaneous access devices, today's peritoneal dialysis catheters still have imperfect hydraulic function, biocompatibility and resistance to infection. Success of Tenckhoff catheters is greatly improved by the proper positioning of deep and subcutaneous cuffs and intraperitoneal segment. Newer peritoneal catheter designs are intended to improve hydraulic function, avoid outflow failure, and diminish exit site infection. These catheter designs serve as excellent alternatives for patients with various types of failure of Tenckhoff catheters. Catheters have been designed for Continuous Flow Peritoneal Dialysis, and have generally been successful in providing high peritoneal dialysis flow rate, but not always successful in optimally distributing flow of peritoneal fluid. Improvements in catheter design may expand the use of peritoneal dialysis as a successful home dialysis therapy. PMID:16485243

    Summary Background: Multicystic peritoneal mesothelioma is a rare disease. It is not certain if it is a benign or a borderline tumor. Although many therapeutic approaches have been used, complete cytoreductive surgery in combination with hyperthermic intraoperative intraperitoneal chemotherapy has gained acceptance. Case Report: A case of multicystic peritoneal mesothelioma in a 16-year old patient is reported. The patient underwent complete cytoreduction and received intraoperative hyperthermic intraperitoneal chemotherapy. The patient is disease-free one year after surgery. Conclusions: Complete cytoreductive surgery in combination with hyperthermic intraoperative intraperitoneal chemotherapy appears to be a rational therapeutic approach in multicystic peritoneal mesothelioma.

    A 32-year-old man on peritoneal dialysis (PD) was hospitalized for seven days due to fever. A diagnosis of yeast-like fungal peritonitis was made by Gram staining. The patient was started on intravenous micafungin and oral fluconazole therapy following removal of the PD catheter. A fungal pathogen was isolated from the peritoneal fluid and identified as Cryptococcus species. Based on antifungal susceptibility testing, the treatment was changed to voriconazole and continued for 3 months. A genetic analysis identified the isolate as Cryptococcus laurentii (C. laurentii). This patient was diagnosed with C. laurentii PD-related peritonitis and was successfully treated with voriconazole and removal of the PD catheter. PMID:25876577

    Ambulatory surgery is on the rise, with an unmet need for optimum pain control in ambulatory surgery centers worldwide. It is important that there is a proportionate increase in the availability of acute pain-management services to match the rapid rise of clinical patient load with pain issues in the ambulatory surgery setting. Focus on ambulatory pain control with its special challenges is vital to achieve optimum pain control and prevent morbidity and mortality. Management of perioperative pain in the ambulatory surgery setting is becoming increasingly complex, and requires the employment of a multimodal approach and interventions facilitated by ambulatory surgery pain specialists, which is a new concept. A focused ambulatory pain specialist on site at each ambulatory surgery center, in addition to providing safe anesthesia, could intervene early once problematic pain issues are recognized, thus preventing emergency room visits, as well as readmissions for uncontrolled pain. This paper reviews methods of acute-pain management in the ambulatory setting with risk stratification, the utilization of multimodal interventions, including pharmacological and nonpharmacological options, opioids, nonopioids, and various routes with the goal of preventing delayed discharge and unexpected hospital admissions after ambulatory surgery. Continued research and investigation in the area of pain management with outcome studies in acute surgically inflicted pain in patients with underlying chronic pain treated with opioids and the pattern and predictive factors for pain in the ambulatory surgical setting is needed.

  7. Transitioning the RN to Ambulatory Care: An Investment in Orientation.

    PubMed

    Allen, Juliet Walshe

    2016-01-01

    Registered nurses (RNs) struggle when transitioning from the inpatient setting to the outpatient clinical environment because it results in a diverse skill-set shift. The RN, considered an outpatient revenue source, experiences a decrease in peer-to-peer relationships, changes in leadership responsibilities, and changes in workgroup dynamics (supervision of unlicensed clinical personnel who function under the direction of the physician, not the RN). Ambulatory organizations find themselves implementing clinical orientation programs that may not delineate the attributes of the RN. This diminishes their value while emphasizing the unlicensed technical skill set. Creating a core RN orientation program template is paramount for the transition of the RN to the ambulatory setting. The literature reveals several areas where improving the value of the RN will ultimately enhance recruitment and retention, patient care outcomes, and leverage the RN role within any organization. Eleven 30-minute in-depth telephone interviews were conducted in addition to 4 nurse observations to explore the lived experience of the RN in ambulatory care. The findings disclosed an overarching theme of nurse isolation and offered insightful underpinnings for the nurse leader as ambulatory growth continues and nurse leaders further endorse the RN presence in the ambulatory setting.

    A compact, ambulatory biometric data acquisition system has been developed for space and commercial terrestrial use. BioWATCH (Bio medical Wireless and Ambulatory Telemetry for Crew Health) acquires signals from biomedical sensors using acquisition modules attached to a common data and power bus. Several slots allow the user to configure the unit by inserting sensor-specific modules. The data are then sent real-time from the unit over any commercially implemented wireless network including 802.11b/g, WCDMA, 3G. This system has a distributed computing hierarchy and has a common data controller on each sensor module. This allows for the modularity of the device along with the tailored ability to control the cards using a relatively small master processor. The distributed nature of this system affords the modularity, size, and power consumption that betters the current state of the art in medical ambulatory data acquisition. A new company was created to market this technology.

    ♦ Background: The efficacy of the phosphate binder lanthanum carbonate has been demonstrated for hemodialysis patients, but no studies have focused on patients undergoing continuous ambulatory peritoneal dialysis (CAPD). We evaluated whether lanthanum carbonate could control phosphate levels in patients on CAPD. ♦ Methods: In this 48-week open-label prospective study, 28 patients on CAPD with a phosphate level of 6 mg/dL or greater were given lanthanum carbonate titrated from 750 mg to 2250 mg daily to achieve a target serum phosphate level of less than 6 mg/dL. The primary efficacy endpoint was reduction of serum phosphate to less than 6 mg/dL. Serum levels of calcium and parathyroid hormone were also evaluated, as were the Ca×P product and adverse effects. ♦ Results: From week 4 to the end of the study at week 48, we observed a significant reduction of serum phosphate to 5.25 ± 0.97 mg/dL from 6.88 ± 1.06 mg/dL at study start (p < 0.01). At the end of the study, 78.6% of participants had achieved the target of less than 6 mg/dL. Because no change of serum calcium occurred, the Ca×P product declined significantly during the study. Intact parathyroid hormone declined gradually over the study period, but the change had not reached significance at the end of the study (p = 0.11). The mean final dose of lanthanum carbonate was 946 mg daily. The only adverse effect reported was mild nausea in 1 patient. ♦ Conclusions: Lanthanum carbonate is an effective phosphate binder that can control serum phosphate and Ca×P product in CAPD patients with hyperphosphatemia. Lanthanum carbonate was well tolerated in our population. PMID:23209037

  14. Unusual presentation of peritonitis with persistent clear aspirate: a case report

    PubMed Central

    2010-01-01

    Introduction Peritonitis is the most frequent complication of peritoneal dialysis. Diagnosis of peritonitis includes symptoms and signs of peritonitis with a cloudy aspirate of more than 100 WBC/ml, as well as positive cultures. Although sterile peritonitis has been reported in the literature, to the best of our knowledge this is the first report of an unusual presentation of peritonitis without any white blood cells in the peritoneal aspirate despite multiple positive peritoneal cultures. Case presentation An 82-year-old Caucasian man who had been on continuous cycling peritoneal dialysis for 12 years was admitted to our hospital with general malaise, loss of appetite, weight loss and somnolence. He did not describe abdominal pain or fever. Even though his peritoneal fluid was consistently negative for leukocytes and clear, he had peritonitis with different organisms consecutively. Conclusions Our case report shows that any patient on peritoneal dialysis presenting with evidence of infection (fever, peripheral leukocytosis) without an obvious cause should have aspirate cultures done even if the aspirate is clear and abdominal pain is absent. Our case report may change the initial work-up and management of these patients. We believe this report is of interest to general medicine and emergency room physicians as well as nephrologists.

    An approximately 5-month-old American Staffordshire terrier was presented with a history of recurrent peritoneal effusion. Abdominal radiographs and ultrasound showed a loculated effusion in the ventral abdomen with dorsal displacement of abdominal organs, hepatomegaly and rounding of liver and splenic margins. Computed tomography demonstrated centrally located gastrointestinal segments surrounded by a thin soft tissue band and a thickened peritoneal lining. At necropsy a fibrous membrane continuous with liver and splenic capsules encapsulated all abdominal organs. Microscopically the abdominal wall and fibrous capsule consisted of an irregular thick layer of hypocellular connective tissue. The final diagnosis was sclerosing encapsulating peritonitis.

    PubMed

    Morinelli, Thomas A; Luttrell, Louis M; Strungs, Erik G; Ullian, Michael E

    2016-08-01

    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.

    2016-01-01

    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 non-specific 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%). PMID:27226904

    2001-11-01

    Conventional treatment of deep venous thrombosis (DVT) has been based, until recently, on non-fractionated heparin by continuous intravenous infusion in hospital until effective anticoagulation could be obtained by oral anticoagulants introduced early. Low molecular weight heparin (LMWH) seems to be as effective and has a better bio-availability, which means that there are fewer adverse effects. This usage has logically led to the increase in the possibilities of treatment of DVT at home. However, certain precautions are necessary, especially the evaluation of the individual patient's risk with this strategy. This requires multidisciplinary collaboration and the respect of strict rules (precise diagnostic objective, hospital admission at the slightest doubt of pulmonary embolism) to demonstrate the value of ambulatory LMWH therapy which would improve patient comfort and allow early mobilisation.

    Objectives Peritonitis is one of the most important causes of treatment failure in peritoneal dialysis (PD) patients. This study describes changes in characteristics of causative organisms in PD-related peritonitis and antimicrobial susceptibility. Methods In this single center study we analyzed retrospective 487 susceptibility profiles of the peritoneal fluid cultures of 351 adult patients with peritonitis from 1979 to 2014 (divided into three time periods, P1-P3). Results Staphylococcus aureus decreased from P1 compared to P2 and P3 (P<0.05 and P<0.01, respectively). Methicillin-resistant S. aureus (MRSA) occurred only in P3. Methicillin-resistant Staphylococcus epidermidis (MRSE) increased in P3 over P1 and P2 (P <0.0001, respectively). In P2 and P3, vancomycin resistant enterococci were detected. The percentage of gram-negative organisms remained unchanged. Third generation cephalosporin resistant gram-negative rods (3GCR-GN) were found exclusively in P3. Cefazolin-susceptible gram-positive organisms decreased over the three decades (93% in P1, 75% in P2 and 58% in P3, P<0.01, P<0.05 and P<0.0001, respectively). Vancomycin susceptibility decreased and gentamicin susceptibility in gram-negatives was 94% in P1, 82% in P2 and 90% in P3. Ceftazidim susceptibility was 84% in P2 and 93% in P3. Conclusions Peritonitis caused by MSSA decreased, but peritonitis caused by MRSE increased. MRSA peritonitis is still rare. Peritonitis caused by 3GCR-GN is increasing. An initial antibiotic treatment protocol should be adopted for PD patients to provide continuous surveillance. PMID:26405797

    Encapsulating peritoneal sclerosis (EPS) is a serious and often fatal complication of long-term peritoneal dialysis (PD) with severe malnutrition and poor prognosis. It causes progressive obstruction and encapsulation of the bowel loops. As EPS becomes more prevalent with longer duration of PD, large multicenter prospective studies are needed to establish its incidence and identify risk factors, therapeutic approach, and prognosis.

    Encapsulating peritoneal sclerosis (EPS) is a devastating but, fortunately, rare complication of long-term peritoneal dialysis. The disease is associated with extensive thickening and fibrosis of the peritoneum resulting in the formation of a fibrous cocoon encapsulating the bowel leading to intestinal obstruction. The incidence of EPS ranges between 0.7 and 3.3% and increases with duration of peritoneal dialysis therapy. Dialysis fluid is hyperosmotic, hyperglycemic, and acidic causing chronic injury and inflammation in the peritoneum with loss of mesothelium and extensive tissue fibrosis. The pathogenesis of EPS, however, still remains uncertain, although a widely accepted hypothesis is the “two-hit theory,” where, the first hit is chronic peritoneal membrane injury from long standing peritoneal dialysis followed by a second hit such as an episode of peritonitis, genetic predisposition and/or acute cessation of peritoneal dialysis, leading to EPS. Recently, EPS has been reported in patients shortly after transplantation suggesting that this procedure may also act as a possible second insult. The process of epithelial–mesenchymal transition of mesothelial cells is proposed to play a central role in the development of peritoneal sclerosis, a common characteristic of patients on dialysis, however, its importance in EPS is less clear. There is no established treatment for EPS although evidence from small case studies suggests that corticosteroids and tamoxifen may be beneficial. Nutritional support is essential and surgical intervention (peritonectomy and enterolysis) is recommended in later stages to relieve bowel obstruction. PMID:25601836

    AIMS Patients with end-stage renal disease (ESRD) are at increased risk of developing complications associated with influenza infection. Oseltamivir is indicated for influenza treatment in ESRD patients, but the disposition is poorly understood in this patient population. This study aimed to characterize the pharmacokinetics and tolerability of oseltamivir in automated peritoneal dialysis (APD) and construct a pharmacokinetic model to assist with optimized dosing. METHODS Ten adults with ESRD were prescribed an aggressive APD regimen consisting of three continuous cycler-assisted peritoneal dialysis (CCPD) sessions during the day and two continuous ambulatory (CAPD) sessions overnight. Oseltamivir was administered as a single 75 mg dose, immediately before APD treatment. RESULTS Oseltamivir was rapidly eliminated via first-pass metabolism, with most of the dose (Fraction metabolized = 0.964) reaching the circulation as the active metabolite, oseltamivir carboxylate. This metabolite was cleared slowly and was quantifiable throughout the sampling interval. The disposition of oseltamivir and oseltamivir carboxylate was described by a two- and a one-compartment model, respectively. Metabolite clearance by CCPD [0.32 l h−1 (70 kg)−1] was 1.9-fold faster than via CAPD [0.17 l h−1 (70 kg)−1], with renal elimination being dominant in patients with residual urine production. Model simulations showed that a single 75 mg dose attained target exposures in patients with negligible or low urine clearance. However, higher doses are recommended for further investigation in patients with high residual renal function. In all patients, oseltamivir was well tolerated. CONCLUSIONS In APD patients with anuria or low residual renal elimination, a single 75 mg dose of oseltamivir produced exposures at the upper end of the safety margin. PMID:25289522

    Changes within nursing demand that a specialty conduct periodic, appropriate practice analyses to continually validate itself against preset standards. This study explicates practice analysis methods using ambulatory care nursing as an exemplar. Data derived from a focus group technique were used to develop a survey that was completed by 499 ambulatory care nurses. The validity of the instrument was assessed using principal components analysis; reliability was estimated using Cronbach's alpha coefficient. The focus group with ambulatory care experts produced 34 knowledge and activity statements delineating ambulatory care nursing practice. The survey data produced five factors accounting for 71% of variance in the data. The factors were identified as initial patient assessment, professional nursing issues and standards, client care management skills, technical/clinical skills, and system administrative operations. It was concluded that practice analyses delineate a specialty and provide input for certification examinations aimed at measuring excellence in a field of nursing. PMID:17665821

    OBJECTIVE: To determine the status of ambulatory care training of core internal medicine residents in Canada. DESIGN: Mail survey. PARTICIPANTS: All 16 program directors of internal medicine residency training programs in Canada. OUTCOME MEASURES: The nature and amount of ambulatory care training experienced by residents, information about the faculty tutors, and the sources and types of patients seen by the residents. As well, the program directors were asked for their opinions on the ideal ambulatory care program and the kinds of teaching skills required of tutors. RESULTS: All of the directors responded. Fifteen stated that the ambulatory care program is mandatory, and the other stated that it is an elective. Block rotations are more common than continuity-of-care assignments. In 12 of the programs 10% or less of the overall training time is spent in ambulatory care. In 11 the faculty tutors comprise a mixture of generalists and subspecialists. The tutors simultaneously care for patients and teach residents in the ambulatory care setting in 14 of the schools. Most are paid through fee-for-service billing. The respondents felt that the ideal program should contain a mix of general and subspecialty ambulatory care training. There was no consensus on whether it should be a block or continuity-of-care experience, but the directors felt that consultation and communication skills should be emphasized regardless of which type of experience prevails. CONCLUSIONS: Although there is a widespread commitment to provide core internal medicine residents with experience in ambulatory care, there is little uniformity in how this is achieved in Canadian training programs.

    Mesothelioma is a neoplasm originating from the mesothelial surface lining cells of the serous human cavities. It may involve the pleura, less frequently the peritoneum rarely, the pericardium, the tunica vaginalis testis and ovarian epithelium. Asbestos has been widely used in industry. A causal relationship between asbestos exposure and pleural, peritoneal and pericardial malign mesothelioma was suggested, the risk of cancer being correlated to cumulate exposure. Studies from National Cancer Institute, USA, show that the malignant mesothelioma is a rare and aggressive asbestos related malignancy. The symptomatology is insidious and poses difficult problems in diagnosis and treatment. This paper presents the case of a 59 year old patient with malignant peritoneal mesothelioma who worked almost 40 years as an electrician, exposed to asbestos fibers. He was hospitalized for important weight loss, abdominal pain and tiredness being diagnosed after imaging tests with a giant tumor, localized at the abdominal upper level, which seems to originate from the spleen's superior pole. During surgery we discovered a tumor with cystic parts, intense vascularized, which turn to be adherent in the upper side to the lower face of the left midriff cupola, to the spleen superior pole and 1/3 middle level of the great gastric curve. It was performed surgical ablation of the tumor, splenectomy with favorable postoperative evolution, the patient being now under chemotherapy treatment. PMID:17283842

    This study is an attempt to address both the extent to which surgical procedures on an outpatient basis substitute cost-effectively for inpatient procedures, and whether or not an insurance policy's financial incentives increase the volume of outpatient surgical procedures. In particular, given an insurance product of a given composition: What is the probability that the insured will have surgery? and if a surgery does take place, what is the probability that it will occur in an outpatient setting? Finally, the article assesses the implication of such products on the total cost of care by quantifying the insurance plans along two parameters, the relative user price for outpatient versus inpatient surgery and the absolute price for the inpatient surgery. The results indicate that insurance policies that offer relatively lower out-of-pocket payments for ambulatory surgery do not increase the probability that surgery will be done in the ambulatory setting. However, higher out-of-pocket payments for surgery, regardless of site, do reduce the surgery rate. There are other patient and market characteristics, especially the availability of freestanding surgery firms, that do influence the location of surgery. PMID:8428814

    J.T. was able to remain home in her familiar environment and receive safe and adequate treatment for her renal disease. J.T. had no infectious episodes or hospitalizations while under this unit's care for 35 months. She was also able to participate in her regular activities of daily living, interact with her family members, and travel on occasion, thus maintaining a good quality of life. Therefore, unit goals for her care were met. J.T.'s experience demonstrates that with proper teaching, preparation, and support from the dialysis care team working with a dedicated family, peritoneal dialysis can be an ideal modality for the treatment of ESRD in people with mental disabilities.

    Management of peritoneal surface malignancies has gradually evolved by the introduction of cytoreductive surgery in combination with intraperitoneal chemotherapy applications. Recently, peritoneal metastases of intraabdominal solid organ tumors and primary peritoneal malignancies such as peritoneal mesothelioma are being treated with this new approach. Selection criteria are important to reduce morbidity and mortality rates of patients who will experience minimal or no benefit from these combined treatment modalities. Management of peritoneal surface malignancies with this current trend is presented in this review. PMID:27528813

    Background 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. Methods 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). Results 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. Conclusions 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. PMID:25314341

    Peritoneal dialysis (PD) is associated with structural and functional alterations of the peritoneal membrane, consisting of fibrosis, angiogenesis, and loss of ultrafiltration capacity. Vitamin D receptor activation (VDRA) plays an important role in mineral metabolism and inflammation, but also antiangiogenic and antifibrotic properties have been reported. Therefore, the effects of active vitamin D treatment on peritoneal function and remodeling were investigated. Rats were either kept naïve to PDF exposure or daily exposed to 10 mL PDF and were treated for five or seven weeks with oral paricalcitol or vehicle control. Non-PDF-exposed rats showed no peritoneal changes upon paricalcitol treatment. Paricalcitol reduced endogenous calcitriol but did not affect mineral homeostasis. However, upon PDF exposure, loss of ultrafiltration capacity ensued which was fully rescued by paricalcitol treatment. Furthermore, PD-induced ECM thickening was significantly reduced and omental PD-induced angiogenesis was less pronounced upon paricalcitol treatment. No effect of paricalcitol treatment on total amount of peritoneal cells, peritoneal leukocyte composition, and epithelial to mesenchymal transition (EMT) was observed. Our data indicates that oral VDRA reduces tissue remodeling during chronic experimental PD and prevents loss of ultrafiltration capacity. Therefore, VDRA is potentially relevant in the prevention of treatment technique failure in PD patients. PMID:26605330

    Peritoneal dialysis (PD) has been extensively used over the past years as a method of kidney replacement therapy for patients with end stage renal disease (ESRD). In an attempt to better understand the properties of the peritoneal membrane and the mechanisms involved in major complications associated with PD, such as inflammation, peritonitis and peritoneal injury, both in vivo and ex vivo animal models have been used. The aim of the present review is to briefly describe the animal models that have been used, and comment on the main problems encountered while working with these models. Moreover, the differences characterizing these animal models, as well as, the differences with humans are highlighted. Finally, it is suggested that the use of standardized protocols is a necessity in order to take full advantage of animal models, extrapolate their results in humans, overcome the problems related to PD and help promote its use.

    Uraemia and long-term peritoneal dialysis (PD) can lead to fibrotic thickening of the peritoneal membrane, which may limit its dialytic function. Peritoneal fibrosis is associated with the appearance of myofibroblasts and expansion of extracellular matrix. The extent of contribution of resident peritoneal fibroblasts to these changes is a matter of debate. Recent studies point to a significant heterogeneity and complexity of the peritoneal fibroblast population. Here, we review recent developments in peritoneal fibroblast biology and summarize the current knowledge on the involvement of peritoneal fibroblasts in peritoneal inflammation and fibrosis.

    There is an obvious trend towards developing ambulatory procedures in gynaecology with ambulatory hysteroscopy as its mainstay. In the recent years, the fast pace of modern technological advances in gynaecologic endoscopy, and particularly in the field of hysteroscopy, have been both thrilling and spectacular. Despite this, the uptake of operative hysteroscopy in ambulatory settings has been relatively slow. There is some apprehension amongst gynaecologists to embark on therapeutic outpatient hysteroscopy, and an organisational change is required to alter the mindset. Although there are best practice guidelines for outpatient hysteroscopy, there are unresolved issues around adequate training and accreditation of future hysteroscopists. Virtual-reality simulation training for operative hysteroscopy has shown promising preliminary results, and it is being aggressively evaluated and validated. This review article is an attempt to provide a useful practical guide to all those who wish to implement ambulatory hysteroscopy services in their outpatient departments. PMID:25979350

    Study Design Cross-sectional study. Objective To assess the current practices of spine surgeons performing ambulatory surgery in the United States. Methods An electronic survey was distributed to members of the International Society for the Advancement of Spine Surgery. Data were initially examined in a univariate manner; variables with a p value < 0.25 were entered into a multiple logistic regression model. All statistical analyses were performed using the SAS System software Version 9.2 (SAS Institute, Inc., Cary, North Carolina, United States). Results Overall, 84.2% of respondents performed some manner of ambulatory spine surgery, and 49.1% were investors in an ambulatory surgery center. Surgeon investors in ambulatory surgery centers were more likely to perform procedures of increased complexity than noninvestors, though limited data precluded a statistical correlation. Surgeons in private practice were more likely to perform ambulatory surgery (94.3%; p = 0.0176), and nonacademic surgeons were both more likely to invest in ambulatory surgery centers (p = 0.0024) and perform surgery at least part of the time in a surgery center (p = 0.0039). Conclusions Though the numbers were too few to calculate statistical significance, there was a trend toward the performance of high-risk procedures on an ambulatory basis being undertaken by those with investment status in an ambulatory center. It is possible that this plays a role in the decision to perform these procedures in this setting versus that of a hospital, where a patient may have better access to care should a complication arise requiring emergent assessment and treatment by a physician. This decision should divest itself of financial incentives and focus entirely on patient safety. PMID:25083356

    2013-01-01

    BACKGROUND: Socialized health systems face fiscal constraints due to a limited supply of resources and few reliable ways to control patient demand. Some form of prioritization must occur as to what services to offer and which programs to fund. A data-driven approach to decision making that incorporates outcomes, including safety and quality, in the setting of fiscal prudence is required. A value model championed by Michael Porter encompasses these parameters, in which value is defined as outcomes divided by cost. OBJECTIVES: To assess ambulatory cleft lip surgery from a quality and safety perspective, and to assess the costs associated with ambulatory cleft lip surgery in North America. Conclusions will be drawn as to how the overall value of cleft lip surgery may be enhanced. METHODS: A value analysis of published articles related to ambulatory cleft lip repair over the past 30 years was performed to determine what percentage of patients would be candidates for ambulatory cleft lip repair from a quality and safety perspective. An economic model was constructed based on costs associated with the inpatient stay related to cleft lip repair. RESULTS: On analysis of the published reports in the literature, a minority (28%) of patients are currently discharged in an ambulatory fashion following cleft lip repair. Further analysis suggests that 88.9% of patients would be safe candidates for same-day discharge. From an economic perspective, the mean cost per patient for the overnight admission component of ambulatory cleft surgery to the health care system in the United States was USD$2,390 and $1,800 in Canada. CONCLUSIONS: The present analysis reviewed germane publications over a 30-year period, ultimately suggesting that ambulatory cleft lip surgery results in preservation of quality and safety metrics for most patients. The financial model illustrates a potential cost saving through the adoption of such a practice change. For appropriately selected patients, ambulatory

    This study investigates the correlation between SBP and repeated paracentesis, and its relation to MELD score, in cirrhotic patients with refractory ascites in an outpatient setting. Through the data base, 148 cirrhotic patients were prospectively included in the study with refractory ascites undergoing relief paracentesis from March 2012 to March 2013. Demographics data, etiology of liver disease, MELD score, and inscription on the waiting list for liver transplantation were analyzed. The ascites removed was analyzed through cellular count and culture for the diagnosis of spontaneous bacterial peritonitis. The cirrhotic patients underwent a total of 854 paracentesis procedures in the ambulatory setting during the study period. Eighty-one patients (54%) were on the waiting list for liver transplantation. Patients on the liver transplant list had higher associated costs due to a higher total number of outpatient paracentesis procedures (394.7 ± 512.3 versus 291.7 ± 384.7) and a higher volume drained per procedure (6.5 ± 8.5 versus 4.8 ± 6.4). There were 28 episodes of SBP (3.3%) diagnosed in 24 patients. In conclusion, the prevalence of asymptomatic SBP in cirrhotic patients with refractory ascites undergoing repeated paracentesis is low. MELD score is not related to spontaneous bacterial peritonitis. PMID:26229528

    Changes in the financing and delivery of hospital ambulatory care are discussed. Ambulatory care encompasses a wide spectrum of clinical services provided to patients who are not confined overnight to an institutional bed as inpatients. There are a large and growing number of ways hospitals and physicians cooperate to provide ambulatory-care services. Technological advancements, which have spurred changes in other sectors of medicine, have also changed patterns of medical practice in ambulatory care. Some of the reasons why hospitals develop and expand ambulatory-care programs relate to the changing demand for health services, the shifting preferences of third-party payers and regulators, competitive influences, diversification of risk, and use of such programs as feeders for inpatient services and as teaching and research settings. Although outpatient revenues are a small portion of total hospital revenues, they are growing more rapidly than inpatient revenues. Changes in the health industry that offer opportunities to hospitals are described, such as the increasing physician supply and the formation of group practices, the climate of cost consciousness and price competition, and the trend toward new corporate structures for hospitals. These changes portend changes for hospital pharmacists and give them the opportunity to increase their clinical roles in providing ambulatory care. PMID:7081250

    This paper describes an experimental model of peritoneal adhesions, in the rat, based on two relatively minor accidents that may occur during abdominal surgery in man: drying of the serosa, and bleeding. Drying alone had little effect; drying plus bleeding consistently produced adhesions to the dried area. Fresh blood alone produced adhesions between the three membranous structures [omentum and pelvic fat bodies (PFBs)]. The formation of persistent adhesions required whole blood. Preformed clots above a critical size induced adhesions even without previous serosal injury; they were usually captured by the omentum and PFBs. If all three membranous structures were excised, the clots caused visceral adhesions. The protective role of the omentum, its structure, and the mechanism of omental adhesions, are discussed. These findings are relevant to the pathogenesis of post-operative adhesions in man. ImagesFig 3Fig 4Fig 5Fig 6Fig 7Fig 12Fig 13Fig 1Fig 2Fig 14Fig 15Fig 8Fig 9Fig 10Fig 11 PMID:5315369

    Indirect arterial blood pressure measurement has not changed substantially since its introduction by Riva-Rocci in 1986, Korotkoff in 1905 and Recklinghausen in 1906. Random measurements in the clinic or practice reflect only incompletely the dynamic nature of the blood pressure. Blood pressure recordings by patients themselves have provided more information through better temporal resolution, however, exact characterization of the pressure response throughout the entire day and, in particular, during physical exertion are not enabled; the latter are especially important with regard to diagnosis and treatment of hypertension. In 1966, therefore, radiotelemetric transmission of direct, continuously-measured arterial blood pressure was developed which enabled beat-to-beat registration of blood pressure, outside the laboratory, during normal daily life and sport activities. The initial results showed a marked variability of the blood pressure during the course of the day (Figure 1). Excessive blood pressure increases were observed during exposure to cold, static and dynamic exercise and to a lesser degree during automobile driving and exposure to heat (Figure 3). Recording of the pressure curves via transmission by radiotelemetry shows a high degree of accuracy and temporal resolution, spatial and situational freedom but is invasive and costly in terms of personnel. The same holds true for direct continuous blood pressure registration and storage on a portable tape recorder. Portable, automatic blood pressure measuring units for ambulatory monitoring employ indirect auscultatory or oscillometric recording with a cuff. As compared with the radiotelemetric direct continuous blood pressure measuring method, the indirect method has subordinate temporal resolution, that is, the measurements are only intermittent.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2676813

    Four peritoneal volume markers (carbon /sup 14/-labeled dextran, dextran blue, radioactive albumin, and hemoglobin) were compared. In six rabbits /sup 14/C-dextran was compared with dextran blue during a 4-hour dwell with a 4.25% dextrose solution. The recovery of /sup 14/C-dextran at the end of the dwell was 71% +/- 3% vs. 92% +/- 1% for dextran blue (P less than 0.001). In six other rabbits, radioactive albumin (RISA) was compared with dextran blue. The recovery of RISA was 78% +/- 4%, compared with 85% +/- 2% for dextran blue (P less than 0.05). The calculated peritoneal volumes, uncorrected for disappearance of the markers, were consistently higher than when correction was made. After correction, the calculated end volumes were similar to actually measured end volumes. In six patients with chronic ambulatory peritoneal dialysis, the intraperitoneal volume during a single dwell of 6 hours was estimated in paired observations with lactated Ringer's solution and 1.5% dextrose dialysate, using simultaneously autologous hemoglobin and RISA. In eight additional patients, a single dwell with 4.25% dextrose dialysate was studied. The recoveries of both markers were related to the osmotic strength of the dialysate. Recoveries were 66.7% +/- 2.3% and 69.6% +/- 0.9% in lactated Ringer's solution, and increased to 81% +/- 3% and 82% +/- 2% in 4.25% dextrose for hemoglobin and RISA, respectively. With each dialysate, after correction for disappearance of the marker, no differences in volume profiles or between calculated or measured end volumes could be found with either hemoglobin or RISA.

    PubMed

    Smith, Jaclyn

    2007-01-01

    Recording cough sounds to objectively quantify coughing was first performed using large reel-to-reel tape recorders more than 40 years ago. Coughs were counted manually, which is an extremely laborious and time-consuming process. Current technologies including digital recording techniques, data compression and improvements in digital storage capacity should make the process of recording and counting coughs suitable for automation; however, to date no accurate, objective cough monitoring device is available. Cough sounds are easily distinguishable from other vocalizations by the human ear and hence it is reasonable to assume that coughs sounds should have characteristic, identifying acoustic properties. However, the acoustic features of spontaneously occurring cough sounds are extremely variable. Furthermore, in even the worst cases of cough, the time spent speaking is an order of magnitude greater than the time spent coughing. It follows that even an algorithm that mistakes only a very small proportion of speech as cough will still have an unacceptable false positive rate. There is a clear need for an objective measure of cough for use in clinical practice, clinical research and trials of novel treatments. In the near future automated ambulatory systems with sufficient accuracy to be of clinical use should be available. PMID:17161969

    The healthcare system remains in a dynamic state of flux. We have all heard the story: the changing healthcare market brings reduced reimbursement for services, increased competition, and steadily increasing supply, maintenance, and equipment costs. Ambulatory surgery centers (ASCs) must keep in sync with this change or fail to survive the current market forces. However, because they represent a small contract to various vendors, many ASCs pay premium prices for inventory while receiving less from Managed Care Plans (MCPs) and Health Maintenance Organizations (HMOs). This dilemma makes control of supply costs a top priority for ASCs. In reality, purchasing is becoming more strategically connected to the ASC balance sheet than ever before. Apart from personnel costs, supply and pharmaceutical purchasing represents the greatest expense category on our financial statement. Harnessing these costs directly relates to bottom line profitability. In addition, while performing cost savings magic, ASCs must maintain patient and surgeon satisfaction with the superior outcomes and state-of-the-art technology their reputations are based upon. Sound impossible? This article details how Surgery Center Plus, Inc. (SCP) implemented a cost containment project. PMID:10167012

    Introduction Internal medicine (IM) interns start continuity clinic with variable ambulatory training. Multiple other specialties have utilized a boot camp style curriculum to improve surgical and procedural skills, but boot camps have not been used to improve interns’ ambulatory knowledge and confidence. The authors implemented and assessed the impact of an intern ambulatory boot camp pilot on primary care knowledge, confidence, and curricular satisfaction. Methods During July 2014, IM interns attended ambulatory boot camp. It included clinically focused case-based didactic sessions on common ambulatory topics as well as orientation to the clinic and electronic medical records. Interns anonymously completed a 15-question pre-test on topics covered in the boot camp as well as an identical post-test after the boot camp. The interns were surveyed regarding their confidence and satisfaction. Results Thirty-eight interns participated in the boot camp. Prior to the boot camp, few interns reported confidence managing common outpatient conditions. The average pre-test knowledge score was 46.3%. The average post-test knowledge score significantly improved to 76.1% (p<0.001). All interns reported that the boot camp was good preparation for clinics and 97% felt that the boot camp boosted their confidence. Conclusions The ambulatory boot camp pilot improved primary care knowledge, and interns thought it was good preparation for clinic. The ambulatory boot camp was well received and may be an effective way to improve the preparation of interns for primary care clinic. Further assessment of clinical performance and expansion to other programs and specialties should be considered. PMID:26609962

    Repeated and long-term exposure to conventional glucose-based peritoneal dialysis fluids (PDFs) with poor biocompatibility plays a central role in the pathogenesis of the functional and structural changes of the peritoneal membrane. We have used immortalized human peritoneal mesothelial cells in culture to assess in vitro the biocompatibility of PDFs. Low pH, high glucose concentration and heat sterilization represent major factors of low biocompatibility. Two recent groups of glucose derivatives have been described. Glucose degradation products (GDPs) are formed during heat sterilization (glycoxidation) and storage. GDPs can bind protein and form AGEs (Advanced Glycation End-products), which can also result from the binding of glucose to free NH2 residues of proteins (glycation). The physiological pH, and the separation of glucose during heat sterilization (low GDP content) in the most recent PDFs dramatically increase the biocompatibility. The choice of PD programs with high biocompatibility PDFs allows preserving the function of the peritoneal membrane. Improvement of PDF biocompatibility may limit the occurrence of chronic chemical peritonitis and may allow long-term PD treatment. PMID:16895663

    ABSTRACT Barium peritonitis is extremely rare, but is difficult to treat and may be life-threatening. Barium suspension leakage from the gastrointestinal tract into the abdominal cavity has a time-dependent and synergistically deleterious effect in patients who have generalized bacterial peritonitis. The severity of barium peritonitis is dependent on the quantity of barium in the abdominal cavity. Barium sulfate leakage results in hypovolemia and hypoproteinemia by worsening the exudation of extracellular fluid and albumin. Abdominal fluid analysis is a useful and efficient method to diagnose barium peritonitis. Serial radiographs may not be a reliable or timely diagnostic technique. Initial aggressive fluid resuscitation and empirical broad-spectrum antibiotic treatment should be instituted promptly, followed quickly by celiotomy. During exploratory surgical intervention, copious irrigation and direct wiping with gauze are employed to remove as much barium as possible. Omentectomy should be considered when needed to expedite barium removal. Despite aggressive medical and surgical treatments, postoperative prognosis is guarded to poor due to complications, such as acute vascular shock, sepsis, diffuse peritonitis, hypoproteninemia, electrolyte imbalance, cardiac arrest, small bowel obstruction related to progression of granulomas and adhesions in the abdominal cavity. Therefore, intensive postoperative monitoring and prompt intervention are necessary to maximize chances for a positive outcome. For those that do survive, small bowel obstruction is a potential consequence due to progression of abdominal adhesions. PMID:24430662

    It is widely accepted that ambulatory care furnished in hospital outpatient department (OPD) settings is more costly than similar care furnished in office settings, but few researchers have explored whether practice patterns differ between the two settings. Differences in practice patterns may account for differences in the overall cost of care associated with these settings. Diagnosis-specific episodes of care were used to compare the costs of treating disease episodes in OPDs and offices. The findings suggest that OPD care is more costly not only because of price, but also because continuity of care is less common and the likelihood of hospital admission is substantially greater.

    Although the life expectancy of patients with end-stage renal disease (ESRD) has improved in recent years, it is still far below that of the general population. In this retrospective study, we compared the survival of patients with ESRD receiving hemodialysis (HD) versus those on peritoneal dialysis (PD). The study was conducted on patients referred to the HD and PD centers of the Emam Khomini Hospital and the Aboozar Children's Hospital from January 2007 to May 2012 in Ahvaz, Iran. All ESRD patients on maintenance HD or PD for more than two months were included in the study. The survival was estimated by the Kaplan-Meier method and the differences between HD and PD patients were tested by the log-rank test. Overall, 239 patients, 148 patients on HD (61.92%) and 91 patients on continuous ambulatory PD (CAPD) (38.55%) with mean age of 54.1 ± 17 years were enrolled in the study. Regardless of the causes of ESRD and type of renal replacement therapy (RRT), one-, two- and three-year survival of patients was 65%, 51% and 35%, respectively. There was no significant difference between type of RRT in one- (P-value = 0.737), two- (P-value = 0.534) and three- (P-value = 0.867) year survival. There was also no significant difference between diabetic and non-diabetic patients under HD and CAPD in the one-, two- and three-year survival. Although the three-year survival of diabetic patients under CAPD was lower than that of non-diabetic patients (13% vs. 34%), it was not statistically significant (P-value = 0.50). According to the results of the current study, there is no survival advantage of PD during the first years of initiation of dialysis, and the one-, two- and three-year survival of HD and PD patients is also similar.

    Tuberculosis peritonitis is a rare manifestation of extrapulmonary tuberculosis. The results of gallium-67 scintigraphy of three patients with tuberculosis peritonitis were reviewed to assess its usefulness in the diagnosis of this condition. Tuberculosis peritonitis was associated with diffuse or focal abdominal localization and decreased hepatic accumulation of gallium-67. These gallium-67 scan features of tuberculosis peritonitis may help to optimize the diagnosis and management of this disease. PMID:10435380

    A service excellence system for ambulatory care pharmacy services is described. An interview was designed to measure the needs, expectations, and priorities of a random sample of ambulatory care patients at a 964-bed county teaching hospital and its clinics to determine trends in patient service and satisfaction. The interviews were conducted by the same interviewers with the same script, and follow-up was continuous for two years. Information was summarized for each question and pharmacy site. In defining "service excellence" from a patient's perspective, it was determined that patients wanted a continuation of low-cost prescriptions, decreased waiting time, a friendlier, more caring staff, and environmental modifications. A service excellence system with key performance indicators was then designed and implemented. This effort included recruiting employees with behaviors that support service excellence, training employees to deliver service excellence, creating an environment that promotes patient satisfaction, and designing an ongoing monitoring system. Next, it was imperative to change the attitudes of staff and existing processes to meet or exceed patients' expectations. This phase addressed such issues as patient waiting time, staff-patient interaction, patients' environmental concerns, and staff ideas for service improvement. Finally, changes in service levels were measured. Overall patient satisfaction increased from 72% to 93% at the maincampus pharmacies. Satisfaction at the smaller sites rose from 85% to 95%, while turnaround time and number of pharmacist full-time-equivalents remained stable. A service excellence program was effective in addressing the service issues of ambulatory care patients at a large teaching hospital. PMID:11556653

    In this essay, the authors provide a definition for those medical care facilities representing a consolidated alternative to traditional hospitalization. These facilities can be basically ascribed to the following patterns: day case surgery; day-hospital activity; home-care. Day case surgery is a complex and, in most cases, interdisciplinary procedure; this type of activity necessitates a pre-hospitalization period and often also a "protected discharge" or even a home-care service. Some specific criteria regarding day surgery activity have been defined as follows: the main criteria have a clinical nature, but they interact with others belonging to a social and structural-organizational order. The Royal College of Surgeons of United Kingdom has officially recognized in 1985 this medical care typology as one of the constituents of surgical care, and has evaluated that at least 1/3 of the overall operations could be carried out as day care surgery. In the United States, besides hospital and ambulatory surgery activity, a new pattern known as "free-standing center" has been promoted; in 1993, 35% of the operations is expected to be carried out in day case surgery centers. As far as Italy is concerned, in 1988 only day-hospital practice has been adequately recognized as an alternative medical care facility to traditional hospitalization. The Emilia Romagna region, in order to increase day case surgery activity, has issued in 1991 a list of 53 DRGs, in which day bed units treatment was possible. Up to now, however, only a small part of these diseases is treated on a day case surgery basis. PMID:1306168

    Context While hospitals remain important centers of gravity in the health system, services are increasingly being delivered through ambulatory care. This shift to ambulatory care is giving rise to new delivery structures, such as retail clinics and urgent care centers, as well as reinventing existing ambulatory care capacity, as seen with the patient-centered medical home model and the movement toward team-based care. To protect the public's interests, oversight of ambulatory care services must keep pace with these rapid changes. With this purpose, in January 2013 the New York Public Health and Health Planning Council undertook a redesign of the regulatory framework for the state's ambulatory care services. This article describes the principles undergirding the framework as well as the regulatory recommendations themselves. Methods We explored and analyzed the regulation of ambulatory care services in New York in accordance with the available gray and peer-reviewed literature and legislative documents. The deliberations of the Public Health and Health Planning Council informed our review. Findings The vision of high-performing ambulatory care should be rooted in the Triple Aim (better health, higher-quality care, lower costs), with a particular emphasis on continuity of care for patients. There is a pressing need to better define the taxonomy of ambulatory care services. From the state government's perspective, this clarification requires better reporting from new health care entities (eg, retail clinics), connections with regional and state health information technology hubs, and coordination among state agencies. A uniform nomenclature also would improve consumers’ understanding of rights and responsibilities. Finally, the regulatory mechanisms employed—from mandatory reporting to licensure to regional planning to the certificate of need—should remain flexible and match the degree of consensus regarding the appropriate regulatory path.

    Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story. PMID:25343532

    Abstract Although numerous previous studies have explored various biomarkers for their ability to predict mortality in end-stage renal disease (ESRD) patients, these studies have been limited by retrospective analyses, mostly prevalent dialysis patients, and the measurement of only 1 or 2 biomarkers. This prospective study was aimed to evaluate the association between 3 biomarkers and mortality in incident 335 ESRD patients starting continuous ambulatory peritoneal dialysis (CAPD) in Korea. According to the baseline NT-proBNP, cTnT, and hsCRP levels, the patients were stratified into tertiles, and cardiovascular (CV) and all-cause mortalities were compared. Additionally, time-dependent ROC curves were constructed, and the net reclassification index (NRI) and integrated discrimination improvement (IDI) of the models with various biomarkers were calculated. We found the upper tertile of NT-proBNP was significantly associated with increased risk of both CV and all-cause mortalities. However, the upper tertile of hsCRP was significantly related only to the high risk of all-cause mortality even after adjustment for age, sex, and white blood cell counts. Moreover, NT-proBNP had the highest predictive power for CV mortality, whereas hsCRP was the best prognostic marker for all-cause mortality among these biomarkers. In conclusions, NT-proBNP is a more significant prognostic factor for CV mortality than cTnT and hsCRP, whereas hsCRP is a more significant predictor than NT-proBNP and cTnT for all-cause mortality in incident peritoneal dialysis patients.

    AIM: To investigate the effect of gastric acid suppressants and prokinetics on peritonitis development in peritoneal dialysis (PD) patients. METHODS: This was a single-center, retrospective study. The medical records of 398 PD patients were collected from January 2000 to September 2012 and analyzed to compare patients with at least one episode of peritonitis (peritonitis group, group A) to patients who never had peritonitis (no peritonitis group, group B). All peritonitis episodes were analyzed to compare peritonitis caused by enteric organisms and peritonitis caused by non-enteric organisms. RESULTS: Among the 120 patients who met the inclusion criteria, 61 patients had at least one episode of peritonitis and 59 patients never experienced peritonitis. Twenty-four of 61 patients (39.3%) in group A and 15 of 59 patients (25.4%) in group B used gastric acid suppressants. Only the use of H2-blocker (H2B) was associated with an increased risk of PD-related peritonitis; the use of proton pump inhibitors, other antacids, and prokinetics was not found to be a significant risk factor for PD-related peritonitis. A total of 81 episodes of peritonitis were divided into enteric peritonitis (EP) or non-enteric peritonitis, depending on the causative organism, and gastric acid suppressants and prokinetics did not increase the risk of EP in PD patients. CONCLUSION: The use of H2B showed a trend for an increased risk of overall PD-related peritonitis, although further studies are required to clarify the effects of drugs on PD-related peritonitis.

    We describe a patient receiving long-term peritoneal dialysis who experienced 2 episodes of peritonitis in successive months caused by unusual bacteria of environmental origin: Agrobacterium radiobacter, Pseudomonas oryzihabitans, and Corynebacterium aquaticum. A radiobacter and P oryzihabitans occurred simultaneously in the first episode of peritonitis, and C aquaticum, in the second episode. The patient's vocation necessitated exposure to moist soiled conditions. Both episodes responded promptly to antibiotics commonly used to treat peritonitis. Although these organisms rarely lead to loss of life and commonly are considered to be contaminants, they can cause symptomatic peritonitis and peritoneal dialysis catheter loss. A review of previous case reports is included. PMID:16310563

    Peritonitis continues to be a major complication of peritoneal dialysis (PD), and adequate treatment is crucial for a favorable outcome. There is no consensus regarding the optimal therapeutic regimen, and few prospective controlled studies have been published. The objective of this manuscript is to review the results of PD peritonitis treatment reported in narrative reviews, systematic reviews, and proportional meta-analyses. Two narrative reviews, the only existing systematic review and its update published between 1991 and 2014 were included. In addition, we reported the results of a proportional meta-analysis published by our group. Results from systematic reviews of randomized control trials (RCT) and quasi-RCT were not able to identify any optimal antimicrobial treatment, but glycopeptide regimens were more likely to achieve a complete cure than a first generation cephalosporin. Compared to urokinase, simultaneous catheter removal and replacement resulted in better outcomes. Continuous and intermittent IP antibiotic use had similar outcomes. Intraperitoneal antibiotics were superior to intravenous antibiotics in reducing treatment failure. In the proportional meta-analysis of RCTs and the case series, the resolution rate (86%) of ceftazidime plus glycopeptide as initial treatment was significantly higher than first generation cephalosporin plus aminoglycosides (66%) and glycopeptides plus aminoglycosides (75%). Other comparisons of regimens used for either initial treatment or treatment of gram-positive rods or gram-negative rods did not show statistically significant differences. The superiority of a combination of a glycopeptide and a third generation cephalosporin was also reported by a narrative review study published in 1991, which reported an 88% resolution rate.

    2013-01-01

    Background This short-term study assessed the efficacy and safety of lanthanum carbonate in the treatment of hyperphosphatemia in dialysis patients; here, we report a prespecified subgroup analysis of patients undergoing peritoneal dialysis. Methods Men and women (n = 39) who had received continuous ambulatory peritoneal dialysis for chronic kidney disease for 6 months or more were enrolled in eight renal medicine departments in the United Kingdom. A 2-week washout period was followed by a 4-week dose-titration phase during which patients received lanthanum carbonate titrated up to 2250 mg/day. This was followed by a 4-week, randomized, placebo-controlled, parallel-group phase during which patients continued to receive either lanthanum carbonate at the titrated dose, or a matched dose of placebo. The main outcome measure was control of serum phosphate levels (1.3-1.8 mmol/l) at the end of the parallel-group phase. Results Serum phosphate was controlled in 3/39 (8%) patients at the beginning of the dose-titration phase (after washout) and in 18/31 (58%) patients treated with lanthanum carbonate at its end. After the parallel-group phase, 60% of lanthanum carbonate-treated patients and 10% of those receiving placebo had controlled serum phosphate. There was no difference in mean (95% confidence interval) serum phosphate levels between groups at randomization: lanthanum carbonate, 1.57 (1.34-1.81) mmol/l; placebo, 1.58 (1.40-1.76) mmol/l (p = 0.96). However, a difference was seen at the end of the parallel-group phase: lanthanum carbonate, 1.56 (1.33-1.79) mmol/l; placebo, 2.25 (1.81-2.68) mmol/l (p = 0.0015). There were no clinically important changes in nutritional parameters and no serious treatment-related adverse events were recorded. Conclusions At doses up to 2250 mg/day, lanthanum carbonate is well tolerated and controls hyperphosphatemia effectively. Treatment with higher doses of lanthanum carbonate may allow patients undergoing peritoneal dialysis the

    Objective Peritoneal dialysis (PD) patients have an increased cardiovascular burden. In this study, we aimed to compare certain PD solutions (Physioneal(®) and Dianeal(®)) in terms of the ambulatory blood pressure, echocardiographic parameters (ECHO), carotid atherosclerosis, endothelial function and serum asymmetric dimethylarginine (ADMA) level. Methods A total of 45 PD patients were enrolled in this prospective randomized controlled study: 23 patients in the Dianeal(®) group and 22 patients in the Physioneal(®) group. Ambulatory blood pressure measurements, echocardiography, carotid artery intima-media thickness measurements and flow mediated dilatation (FMD) and ADMA values were obtained at baseline and 12 months. Results The baseline parameters were similar between the groups with respect to the echocardiographic parameters, 24-hour ambulatory blood monitoring measurements and ADMA and FMD levels. All 24-hour blood pressure monitoring measurements, except for the average daytime systolic blood pressure, were significantly decreased in both groups at the first year. In the Physioneal(®) group, a significant decrease was observed with regard to the ADMA levels. Considering the FMD values, significant augmentation was seen at the end of the first year in both groups. Improvements in the FMD measurements were prominent in the Physioneal(®) group; however, this finding was not statistically significant. Conclusion The use of solutions with a neutral pH in PD patients results in decreased ADMA levels, which may be an important contributor to reductions in the incidence of cardiovascular events and deaths in this population.

    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.

    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.

    Introduction: In patients undergoing chronic dialysis, several factors appear to influence the occurrence of cardiac abnormalities. The aim of our study was to evaluate the effects of two different methods of renal replacement therapy (chronic haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD)) on left ventricular (LV) diastolic function. Patients and Methods: We enrolled 63 patients: 21 patients on CAPD, and 42 age- and gender-matched patients on HD; 35 patients were men (55.6%). Median of age was 46.4 (35-57) years. The median duration of renal replacement therapy was 3(2-5) years. Results: The two groups (HD vs PD) were similar concerning body mass index, dialysis duration and cardiovascular risk factors. The comparison of echocardiographic parameters showed statistically significant differences between two groups, regarding the presence of calcification, cardiac effusion, severely abnormal left ventricular hypertrophy(LVH) and the ratio of mitral velocity to early diastolic velocity of the mitral annulus (E/e’) >13 (p= 0.001, p= 0.003, p= 0.02, p= 0.004, respectively). In multivariate analysis, an E/e’>13 was higher in PD group ( OR= 5.8, CI [1.3-25.5], p=0.002). Conclusion: The method of dialysis seems to influence LV diastolic function. We observed a higher prevalence of diastolic LV dysfunction in the PD group. Echocardiographic follow up is essential as this could improve the management of cardiovascular complications in dialysis patients. PMID:27583042

    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

    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.

    Current economic conditions make the practice of equine medicine challenging, to say the least. The downward trend in the US economy has had a huge impact on horse owners and equine veterinarians alike. Horses are expensive to keep; as such, economics are the driving factor in the problem of the unwanted horse. Under these conditions, efficient equine ambulatory practices are well-suited to weather the economic storm. As contributors to this issue of Veterinary Clinics of North America note, one can practice high-quality medicine and surgery without the overhead and expense of a large clinic. Ambulatory practitioners certainly face formidable challenges, but they also have opportunities to establish and secure a good future. PMID:22640575

    Conventional ambulatory electrocardiogram (ECG) (Holter) monitoring involves 2 or 3 surface leads recorded with electrode positions and signal characteristics that are different from diagnostic quality 12-lead ECGs due to the limitations imposed by technology on the ambulatory recorders. The rapid pace of technological development for medical devices, particularly electrocardiography, has now enabled the recording of diagnostic quality 12-lead ECG waveforms for extended time periods. This capability allows Holter recording to become another source for diagnostic 12-lead ECG records on a par with other modalities such as resting ECG and exercise stress testing. Additionally, other diagnostic techniques such as S-T segment analysis and Q-T interval analysis that rely on diagnostic quality waveforms can now be applied. All of these enhancements to the traditional Holter modality have altered the regulatory perspective of these devices, since the enhancements may represent a new intended use for the device.

    The purpose of this study was to determine the ability of ambulatory blood pressure monitoring to identify youths with chronic blood pressure elevation. Nineteen adolescent boys were studied, ten had 5-year average systolic or diastolic pressures above the 95th percentile, nine had normal pressure. A Del Mar Avionics Pressurometer III system recorded an average of 121 readings on each subject. The coefficients of variation for pressure were similar for hypertensive and normotensive individuals. During classes, eight of the ten hypertensive youths had elevated pressures in over half of the measurements. Also during these classes eight of ten hypertensive boys had average systolic or diastolic pressure above the 95th percentile, whereas only one of nine normotensive boys had average pressures above this level. We suggest that schooltime ambulatory pressures may be most useful in classifying the blood pressure trend in a youth. PMID:2346634

    Background: High cost of maintenance hemodialysis (HD) and continuous ambulatory peritoneal dialysis (PD) in India has made renal replacement therapy out of reach of many patients with end stage renal disease (ESRD). Repeated puncture PD although inferior to HD biochemically, is easily and freely available across Rajasthan, India, and is simple to perform, and does not require sophisticated machines, thus making it an attractive option for dialysis for ESRD. Aim: To analyze the outcomes of periodic PD in patients with ESRD requiring dialysis support. Subjects and Methods: A prospective study analyzing the data of patients who underwent PD between August 2010 and January 2013 in Sawai Man Singh Hospital, Jaipur, India was conducted. Patients were divided into three groups based on the time period between first and second session of PD. Detailed demographic and clinical data during the study period were collected along with PD related complications. The main outcome studied was technique survival 1 year post initiation of PD. Results: 234 patients received an initial session of PD, of which 174 had a good response and were included in the study. 19 patients received the second PD within 7 days of first (Group 1), 45 patients within 8–14 days (Group 2) and 110 patients within 15–21 days (Group 3). The overall 1 year technique survival was 68.4% (91/133), with a rate of 50% (5/10), 56.8% (21/37), and 75.6% (65/86) for Group 1, Group 2, and Group 3, respectively. The time duration between first and second PD proved to be reliable indicator of the subsequent response, with a technique survival rate significantly lower in Group 1 patients compared to Groups 2 and 3 (P = 0.04). Median dialysis free days were 11, 16 and 21 days in Group 1, Group 2, and Group 3, respectively. Peritonitis rate observed was 2.1% (49/2261) during the study period. Conclusion: Periodic PD is a simple, safe and cheap procedure, which can be considered as used as a palliative measure in

    Pleural effusions are a common finding in patients admitted on the medical take. This case decribes a patient using peritoneal dialysis who presented with progressive dyspnoea. Clinical examination and chest x-ray confirmed the presence of a pleural effusion. Thoracocentesis confirmed a 'sweet' effusion (higher pleural: serum glucose content), suggesting a pleuro-peritoneal leak. Optimal management involved switch from peritoneal to haemodialysis and referral to a specialised renal unit. This case highlights the need to consider the diagnosis of pleuro-peritoneal leak in patients using peritoneal dialysis who present to the acute medical unit with pleural effusion. PMID:26305084

    This paper presents the design of a compact, wearable, rechargeable acceleration recorder to support long-term monitoring of ambulatory patients with motor disorders, and of software to display and analyze its output. The device consists of a microcontroller, operational amplifier, accelerometer, SD card, indicator LED, rechargeable battery, and associated minor components. It can operate for over a day without charging and can continuously collect data for three weeks without downloading to an outside system, as currently configured. With slight modifications, this period could be extended to several months. The accompanying software provides flexible visualization of the acceleration data over long periods, basic file operations and compression for easier archiving, annotation of segments of interest, and functions for calculation of various parameters and detection of immobility and vibration frequencies. Applications in analysis of gait and other movements are discussed.

    Peritoneal fluid dwell impacts the peritoneum by creating an abnormal physiological microenvironment. Little is known about the precise effects of fluid dwell on the peritoneum, and no adequate in vitro models to analyze the impact of fluid dwell have been established. In this study, we developed a peritoneal fluid dwell model combined with an artificial peritoneal cavity and fluid stirring generation system to clarify the effects of different dwelling solutions on the peritoneum over time. To replicate the peritoneal cavity, we devised a reconstructed peritoneal cavity utilizing a mesothelial layer, endothelial layer, and collagen membrane chamber. The reconstructed peritoneal cavity was infused with Dulbecco's modified Eagle's medium, saline, lactated Ringer's solution or peritoneal dialysis solution with repeated 4-h dwells for 10 or 20 consecutive days. The above-described solutions induced epithelial-mesenchymal transition (EMT) and hyperplasia of mesothelial cells. All solution types modulated nitric oxide synthase activities in mesothelial and endothelial cells and nitric oxide concentrations in dwelling solutions. Inhibition of nitric oxide synthase activity acted synergistically on mesothelial EMT and hyperplasia. The present findings suggest that solutions infused into the peritoneal cavity are likely to affect nitric oxide production in the peritoneum and promote peritoneal fibrosis. Our newly devised peritoneal cavity model should be a promising tool for understanding peritoneal cellular kinetics and homeostasis. PMID:26318752

    Chronic exposure to sterile peritoneal dialysis (PD) solutions is associated with microvascular and interstitial changes within the blood–peritoneal barrier (peritoneum). These changes are commonly linked to loss of peritoneal function over time, presumably because of angiogenesis-related increased vascular area. However, the effects on peritoneal microvascular function of chronic peritoneal exposure to PD solutions are unknown. The present study examined peritoneal microvascular function after chronic exposure to sterile PD solution. Six rats underwent permanent catheter insertion under anesthesia. Three rats were treated with approximately 16 mL conventional PD solution daily for 6 weeks; catheter insertion controls received 1 mL saline daily. At 6 weeks, visceral peritoneal microvascular function was assessed in vivo using intravital microscopy. Endothelial cell functions were assessed using messenger RNA (mRNA) gene microarray analysis. In both groups, significant angiogenesis was seen, predominantly in the base of the mesentery. Sensitivity and reactivity of the intestinal visceral peritoneal pre-capillary arterioles (A3 arterioles, 8 – 15μm in diameter) were decreased in the catheter controls, but not in the chronic PD infusion rats. Chronic catheter presence increased the expression of 18 genes in the controls as compared with 12 genes in the chronic infusion rats. In both groups, expression of fibronectin, integrin-β, integrin-α5, collagen type XVIII-α1, and matrix metalloproteinase was enhanced. Endothelial expression of proinflammatory genes (interleukin-1β tissue pathway inhibitor, chemokine ligand 2) was enhanced by chronic catheter insertion, but not after chronic PD fluid infusion. Increased expression of genes encoding proteins involved in inflammation and tissue remodeling results from peritoneal catheter–related endothelial cell activation. Chronic exposure of the nonuremic peritoneum to sterile PD solutions overrides the catheter

    Benign multicystic mesothelioma is a rare tumour that originates from the abdominal peritoneum with a predisposition to the pelvic peritoneum. It typically affects women of reproductive age. There have been less than 200 cases of this rare neoplasia reported to date. We present the case of a 35-year-old woman who was referred to our centre because of the detection of a peritoneal carcinomatosis during a gynaecological exam. A diagnostic laparoscopy was performed. The findings included multiple cysts appearing as ‘a bunch of grapes’ occupying the omentum. Biopsies were taken during the surgery and the results showed benign multicystic peritoneal mesothelioma. Benign multicystic mesothelioma can simulate other conditions, such as malignant ovarian tumours or cystic lymphangioma. It is often diagnosed accidentally during surgery performed for another reason. The diagnosis is interoperative, observing multicystic structures grouped as a ‘bunch of grapes’ containing clear fluid with thin walls made of connective tissue. Immunohistochemistry confirmed mesothelial origin. Surgery is considered the treatment of choice and is based on the removal of the cysts from the abdominal cavity. Hyperthermic intraperitoneal chemotherapy can be considered as a primary treatment in patients with recurrences or even as a part of primary treatment associated with surgery. Survival at 5 years is 100% and invasive or malignant progression is extraordinary. The treatment approach should be multidisciplinary, and the patient should be referred to a referral centre.

    Background: Spillage of bile and gallstones due to accidental perforation of the gallbladder wall is often encountered during laparoscopic cholecystectomy. Although spilled stones were once considered harmless, there is increasing evidence that they can result in septic or other potential complications. Case Report: We report a case of spilled gallstones mimicking peritoneal metastases on radiological investigations; diagnosis was confirmed by diagnostic laparoscopy. Conclusion: Every effort should be made to retrieve spilled gallstones during laparoscopic cholecystectomy. When all the stones cannot be retrieved, it should be documented in the patient's medical records to avoid delay in the diagnosis of late complications. Diagnostic laparoscopy is useful when the radiological investigations are inconclusive. PMID:19366546

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

    The author reviews briefly the history of peritoneal dialysis, and highlights the significance of the work of two Hungarian nephrologists, Stephen I. Vas and István Taraba . By now, peritoneal dialysis has been considered as equal renal replacement modality compared to haemodialysis. It is even more advantageous in the protection of the patients' residual renal function, morbidity-mortality indices, and quality of life peritoneal dialysis in the first two years. From economical point of view peritoneal dialysis is less expensive than hemodialysis, therefore in the future its greater role can be expected in the treatment of more and more renal patients. The recently achieved technical development, and also the more widespread use of the automated peritoneal dialysis machines contribute to quality improvement. The peritoneal dialysis therapy, by the patients' self-treatment, establishes a new kind of relationship between the patients and the medical personnel; there is a growing requirement for patient education, the patients' self-esteem and cooperation increase, which altogether provides better results in rehabilitation and higher quality of life. Our national peritoneal dialysis utilization falls behind the European achievements, but has been growing dynamically, and we can expect an increase of the number of renal patients on peritoneal dialysis.

    Management of the pregnant patient on peritoneal dialysis (PD) is potentially challenging because uterine enlargement may negatively affect catheter function and prescribed dwell volumes. Additional reports of the management of these patients are needed. Here, we describe a near-full-term delivery in a 27-year-old woman who had been on dialysis for 7 years. Peritoneal dialysis was continued during the entire pregnancy. In the third trimester, a higher delivered automated PD volume allowed for adequate clearance and control of volume status. A decision to hospitalize the patient to limit activity and facilitate the delivery of increased dialysate is believed to have contributed to the successful outcome for mother and infant. Our report discusses the management of this patient and reviews published dialysis prescriptions used during the third trimester of pregnancy in patients treated with PD. PMID:24711639

    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. PMID:26713828

  1. Optimising postoperative pain management in the ambulatory patient.

    PubMed

    Shang, Allan B; Gan, Tong J

    2003-01-01

    Over 60% of surgery is now performed in an ambulatory setting. Despite improved analgesics and sophisticated drug delivery systems, surveys indicate that over 80% of patients experience moderate to severe pain postoperatively. Inadequate postoperative pain relief can prolong recovery, precipitate or increase the duration of hospital stay, increase healthcare costs, and reduce patient satisfaction. Effective postoperative pain management involves a multimodal approach and the use of various drugs with different mechanisms of action. Local anaesthetics are widely administered in the ambulatory setting using techniques such as local injection, field block, regional nerve block or neuraxial block. Continuous wound infusion pumps may have great potential in an ambulatory setting. Regional anaesthesia (involving anaesthetising regional areas of the body, including single extremities, multiple extremities, the torso, and the face or jaw) allows surgery to be performed in a specific location, usually an extremity, without the use of general anaesthesia, and potentially with little or no sedation. Opioids remain an important component of any analgesic regimen in treating moderate to severe acute postoperative pain. However, the incorporation of non-opioids, local anaesthetics and regional techniques will enhance current postoperative analgesic regimens. The development of new modalities of treatment, such as patient controlled analgesia, and newer drugs, such as cyclo-oxygenase-2 inhibitors, provide additional choices for the practitioner. While there are different routes of administration for analgesics (e.g. oral, parenteral, intramuscular, transmucosal, transdermal and sublingual), oral delivery of medications has remained the mainstay for postoperative pain control. The oral route is effective, the simplest to use and typically the least expensive. The intravenous route has the advantages of a rapid onset of action and easier titratibility, and so is recommended for the

    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.

    Peritoneal fibrosis (PF), a serious pathophysiology of peritoneal dialysis (PD), is implicated in various types of chronic inflammation. In the present study, we examined the benefits of interleukin (IL)-10, which exerts anti-inflammatory effects, in an experimental rat model of methylglyoxal (MGO)-induced PF. We injected an adeno-associated virus (AAV) vector encoding rat IL-10 or enhanced green fluorescent protein (GFP) into male Sprague-Dawley rats at 6 weeks of age. Four weeks later, the rats received continuous peritoneal injections of conventional PD fluid (PDF) with MGO for 3 weeks. Then, the peritoneal histology and the expression levels of fibrogenic mediators and proinflammatory cytokines were analyzed. The rats demonstrating persistent IL-10 expression showed significantly reduced fibrous peritoneal thickening compared with those with GFP expression. The infiltration of macrophages, the expression of tumor necrosis factor-α, IL-1β, IL-6, transforming growth factor-β1, Snail, and matrix metalloproteinase 2 genes as well as the proliferation of mesenchymal-like mesothelial cells augmented by MGO were all significantly suppressed by IL-10 expression. IL-10 also abrogated the extent of MGO-induced bowel adhesions mimicking a cocoon-like mass. Our findings provide valuable insight into the potential benefit of immunomodulation with IL-10 as one potentially effective therapeutic strategy for preventing the onset of peritoneal injury resulting in PF.

    Background To compare the burden of central line-associated bloodstream infections (CLABSIs) in ambulatory versus inpatient pediatric oncology patients, and identify the epidemiology of and risk factors associated with ambulatory CLABSIs. Procedure We prospectively identified infections and retrospectively identified central line days and characteristics associated with CLABSIs from January 2009 to October 2010. A nested case–control design was used to identify characteristics associated with ambulatory CLABSIs. Results We identified 319 patients with central lines. There were 55 ambulatory CLABSIs during 84,705 ambulatory central line days (0.65 CLABSIs per 1,000 central line days (95% CI 0.49, 0.85)), and 19 inpatient CLABSIs during 8,682 inpatient central line days (2.2 CLABSIs per 1,000 central lines days (95% CI 1.3, 3.4)). In patients with ambulatory CLABSIs, 13% were admitted to an intensive care unit and 44% had their central lines removed due to the CLABSI. A secondary analysis with a sub-cohort, suggested children with tunneled, externalized catheters had a greater risk of ambulatory CLABSI than those with totally implantable devices (IRR 20.6, P < 0.001). Other characteristics independently associated with ambulatory CLABSIs included bone marrow transplantation within 100 days (OR 16, 95% CI 1.1, 264), previous bacteremia in any central line (OR 10, 95% CI 2.5, 43) and less than 1 month from central line insertion (OR 4.2, 95% CI 1.0, 17). Conclusions In pediatric oncology patients, three times more CLABSIs occur in the ambulatory than inpatient setting. Ambulatory CLABSIs carry appreciable morbidity and have identifiable, associated factors that should be addressed in future ambulatory CLABSI prevention efforts.

    AIM: To investigate the efficacy of effluent biomarkers for peritoneal deterioration with functional decline in peritoneal dialysis (PD). METHODS: From January 2005 to March 2013, the subjects included 218 PD patients with end-stage renal disease at 18 centers. Matrix metalloproteinase-2 (MMP-2), interleukin-6 (IL-6), hyaluronan, and cancer antigen 125 (CA125) in peritoneal effluent were quantified with enzyme-linked immunosorbent assay. Peritoneal solute transport rate was assessed by peritoneal equilibration test (PET) to estimate peritoneal deterioration. RESULTS: The ratio of the effluent level of creatinine (Cr) obtained 4 h after injection (D) to that of plasma was correlated with the effluent levels of MMP-2 (ρ = 0.74, P < 0.001), IL-6 (ρ = 0.46, P < 0.001), and hyaluronan (ρ = 0.27, P < 0.001), but not CA125 (ρ = 0.13, P = 0.051). The area under receiver operating characteristic curve for the effluent levels of MMP-2, IL-6, and hyaluronan against high PET category were 0.90, 0.78, 0.62, and 0.51, respectively. No patient developed new-onset encapsulating peritoneal sclerosis for at least 1.5 years after peritoneal effluent sampling. CONCLUSION: The effluent MMP-2 level most closely reflected peritoneal solute transport rate. MMP-2 can be a reliable indicator of peritoneal deterioration with functional decline. PMID:26981446

    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. PMID:22547910

    Background and Objectives: Despite significant advances in laparoscopic instrumentation and techniques, injury to intraabdominal structures remains a potentially serious complication of peritoneal access. Consensus on the best method to obtain peritoneal access is lacking. A safe technique that does not rely on direct visualization of the abdominal layers could shorten the learning curve for surgeons and potentially be adopted by other physicians for a variety of nonsurgical indications for peritoneal entry. Methods: A prospective series of 99 consecutive patients who underwent upper-abdominal laparoscopic surgery performed by a single surgeon between January 2009 and June 2010 was reviewed. The method used to obtain peritoneal access was the fluid-based peritoneal entry indication technique (C-PET) with the EndoTIP trocar. Results: Successful abdominal entry using C-PET was achieved in 90 (90.9%) of the patients; no trocar-related injuries or other injuries associated with peritoneal access occurred. The mean time from incision to confirmed peritoneal access was 21.4 s (range, 12 to 65). Of the 9 cases in which C-PET did not successfully gain entry, 6 occurred during the first 20 surgeries and only 3 in the final 79. Conclusions: C-PET is simple, safe, timely, and effective for gaining peritoneal access during laparoscopic abdominal surgeries. In this series, C-PET produced no complications and proved effective across a wide variety of patients, including the obese and those who had had previous surgery. Furthermore, C-PET does not require visual recognition of anatomic layers and potentially could easily be taught to nonsurgeon physicians who perform peritoneal access. PMID:23484564

    Long-term oxygen therapy may limit a patient's ability to remain active and may be detrimental to the rehabilitation process. This study aimed to determine the effect of ambulatory oxygen on quality of life and exercise capacity in patients with chronic obstructive pulmonary disease fulfilling the usual criteria of long-term oxygen therapy. In a 1-yr, randomised, three-period, crossover trial, 24 patients (mean age 68 yrs; mean arterial partial pressure of oxygen at rest 7.1 kPa (53 mmHg)) were allocated to one of the six possible sequences generated by three interventions: 1) standard therapy (home oxygen therapy with an oxygen concentrator only); 2) standard therapy plus as-needed ambulatory oxygen; and 3) standard therapy plus ambulatory compressed air. The comparison of ambulatory oxygen versus ambulatory compressed air was double blind. The main outcomes were quality of life (Chronic Respiratory Questionnaire), exercise tolerance (6-min walk test) and daily duration of exposure to oxygen therapy. The trial was stopped prematurely after an interim analysis. On average, the patients used few ambulatory cylinders (7.5 oxygen cylinders versus 7.4 compressed air cylinders over a 3-month study period). Ambulatory oxygen had no effect on any of the outcomes. In conclusion, the current results do not support the widespread provision of ambulatory oxygen to patients with oxygen-dependent chronic obstructive pulmonary disease. PMID:15929958

    Introduction Peritonitis continues to be one of the major infectious problems confronting a surgeon. Mannheim Peritonitis Index (MPI), Physiological and Operative Severity Score for en Umeration of Mortality (POSSUM) and Morbidity and sepsis score of Stoner and Elebute have been devised for risk assessment and for prediction of postoperative outcome. Aim The aim of this study was to find the accuracy of these scores in predicting outcome in terms of mortality in patients undergoing exploratory laprotomy for perforation peritonitis. Materials and Methods The prospective study was carried out in 100 diagnosed cases of perforation at our centre in a single unit over a period of 21 months from December 2012 to August 2014. Study was conducted on all cases of peritonitis albeit primary, tertiary, iatrogenic and those with age less than 12 years were excluded from the study. All the relevant data were collected and three scores were computed from one set of data from the patient. The main outcome measure was survival of the patient. The Receiver Operator Characteristics (ROC) curves were obtained for the three scores. Area Under the Curves (AUC) was calculated. Sensitivity and specificity were calculated at a cut off point obtained from the ROC curves. Results POSSUM had an AUC of 0.99, sepsis score had an AUC of 0.98 and MPI had an AUC of 0.95. The cut off point score of 51 for POSSUM had an accuracy of 93.8 and positive predictive value of 70.5, the score of 29 for MPI had an accuracy of 82.8 and positive predictive value of 46 and the score of 22 for sepsis score had an accuracy of 95.9 and positive predictive value of 86.67. Conclusion POSSUM score was found to be superior in prediction of mortality as compared to sepsis score of Stoner and Elebute and MPI. POSSUM and MPI over predicted mortality in some cases. None of these scores are strictly preoperative. PMID:27134924

    Currently, tuberculosis remains a major public health problem worldwide. Peritoneal tuberculosis occurs in approximately 1% of all of tuberculosis cases and is rarely observed in children. Diagnosis and treatment delays caused by mimicking many other intra-abdominal diseases can lead to increases in morbidity and mortality. Here, we present a case of a four-year-old child with tuberculosis peritonitis who was diagnosed by laparoscopic biopsy and histopathological examination and recovered with antituberculosis therapy. Peritoneal tuberculosis should be considered in younger patients and adults with fever, abdominal pain and weight loss in endemic areas. PMID:25868903

  1. Home and ambulatory blood pressure monitoring: when? who?

    2013-01-01

    Blood pressure measurement in the diagnosis and management of hypertension, including the technique required for ambulatory blood pressure monitoring and home blood pressure monitoring, will be reviewed in this article. Home and ambulatory measurements are widely used, both to confirm the diagnosis and to improve adherence to therapy. The major advantage of out-of-office blood pressure monitoring is that it provides a large number of blood pressure measurements away from the medical environment, which represents a more reliable assessment of actual blood pressure than office blood pressure. The advantage of ambulatory blood pressure monitoring is its unique ability to measure nocturnal blood pressure. Although not fully validated in large-scale clinical trials, ambulatory blood pressure monitoring appears to correlate best with prognosis. Ambulatory blood pressure monitoring and home blood pressure monitoring provide somewhat different information on the subject's blood pressure status, and the two methods should thus be regarded as complementary, rather than competitive or alternative.

    Government policies and community expectations in Australia continually lead to calls for healthcare change. These changes are often met with resistance from clinicians and managers. Making change happen requires consideration of the way policies, culture, context, shared vision and leadership can drive or impede change. This reflective case study critically investigates one change process; the evolution of a Sub-acute Ambulatory Care Services (SACS) program in an Australian regional hospital over a 3-year period. The new Community Rehabilitation Services (CRS) program evolved from a merger of Centre and Home Based Rehabilitation (CBR and HBR). Hospital amalgamations, closures and privatisation, and the Department of Health policy relating to SACS, ambulatory care and rehabilitation were some of the key elements explored in this paper.

    Twenty-two hypertensive patients were monitored during two separate drug-free occasions with a Del Mar Avionics ambulatory device. Blood pressure loads (percentage of systolic and diastolic readings more than 140 and 90 mmHg, respectively) and mean BP were measured both to determine their reproducibility and to examine how they correlate with each other. The systolic and diastolic mean awake BPs for day 1 and day 2 were 140/93 mmHg and 140/91 mmHg, respectively, and BP loads were 45%/55% and 43%/54%. Moreover, mean BP loads correlated highly (r = 0.93) with mean BP values taken on the same day. Both ambulatory mean SBP and BP load were highly reproducible (r = 0.87 and 0.80, respectively, during the awake hours), and mean DBP and load were fairly reproducible (r = 0.59 and 0.39, respectively, during the awake hours). Clinically, however, both were consistent from day 1 to day 2. Mean and individual standard deviations also were reproducible for both systolic and diastolic pressures and loads. PMID:2096203

    Over the next decade, the Internet and related technologies will revolutionize the administrative and clinical practices of ambulatory care, enhancing the ability of physicians to provide quality care, enabling "virtual care teams" to help patients deal effectively with acute episodes and chronic conditions, and reducing the cost of care. Like any major paradigm shift, this change will not happen overnight. Nor will it be without cost. The explosion of venture capital and meteoric rise of the Nasdaq in 1999 reflected the promise of the Internet to revolutionize many aspects of American business. The Nasdaq's equally rapid descent in 2000 reflected a growing realization that this change will not be free--that "creative destruction," to use Schumpeter's term, will inevitably require significant investment and produce substantial losses. This article takes a longer term view than the ups and downs in the stock market. We believe the forces unleashed by the Internet are inexorable and that 10 years from now we will look back at the millennium's first decade as a period when the practice of ambulatory medicine was transformed by communication technology.

    Here, we report 2 patients with gastric cancer and peritoneal dissemination who were successfully treated with chemotherapy after undergoing treatment for an oncologic emergency caused by peritoneal dissemination. Case 1 involved obstruction of the sigmoid colon caused by peritoneal dissemination. After urgent colostomy, S-1/IP IV paclitaxel chemotherapy was introduced. The patient continued the therapy for 2 years and 2 months. Case 2 involved acute renal failure due to bilateral ureter obstruction and obstructive jaundice caused by peritoneal dissemination. This patient underwent emergency treatment consisting of Double-J ureteral stent insertion and endoscopic nasobiliary drainage. He was successfully started on chemotherapy with S-1/oxaliplatin/IP paclitaxel. He continued the therapy for 8 months without symptoms. Aggressive treatment might be effective for advanced gastric cancer showing oncologic emergency. PMID:26805263

    2015-01-01

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

    Peritoneal 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

    Peritoneal seedings of a colorectal tumor represent the second most frequent site of metastasis (after the liver). In the era of 5-fluorouracil (5-FU)-only chemotherapy, the prognosis was poor for colorectal cancer with peritoneal metastases. Within the last few years, new chemotherapeutic and targeted agents have improved the prognosis; however, the response to these treatments seems to be lower than that for liver metastases. The combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have further improved both disease-free survival and overall survival. Keeping this in mind, every patient presenting with peritoneal metastases from colorectal cancer should be evaluated and receive adequate treatment, if possible in the above-mentioned combination. This paper reviews recent advancements in the therapy of peritoneal carcinomatosis. PMID:26424828

    Background. Exercise at moderate intensity may confer neuroprotective benefits in multiple sclerosis (MS), however it has been reported that people with MS (PwMS) exercise less than national guideline recommendations. We aimed to determine predictors of moderate to vigorous exercise among a sample of older Canadians with MS who were divided into ambulatory (less disabled) and non-ambulatory (more disabled) groups. Methods. We analysed data collected as part of a national survey of health, lifestyle and aging with MS. Participants (n = 743) were Canadians over 55 years of age with MS for 20 or more years. We identified 'a priori' variables (demographic, personal, socioeconomic, physical health, exercise history and health care support) that may predict exercise at moderate to vigorous intensity (>6.75 metabolic equivalent hours/week). Predictive variables were entered into stepwise logistic regression until best fit was achieved. Results. There was no difference in explanatory models between ambulatory and non-ambulatory groups. The model predicting exercise included the ability to walk independently (OR 1.90, 95% CI [1.24-2.91]); low disability (OR 1.50, 95% CI [1.34-1.68] for each 10 point difference in Barthel Index score), perseverance (OR 1.17, 95% CI [1.08-1.26] for each additional point on the scale of 0-14), less fatigue (OR 2.01, 95% CI [1.32-3.07] for those in the lowest quartile), fewer years since MS diagnosis (OR 1.58, 95% CI [1.11-2.23] below the median of 23 years) and fewer cardiovascular comorbidities (OR 1.55 95% CI [1.02-2.35] one or no comorbidities). It was also notable that the factors, age, gender, social support, health care support and financial status were not predictive of exercise. Conclusions. This is the first examination of exercise and exercise predictors among older, more disabled PwMS.

    Premature ventricular contractions (PVCs) are associated with an increased risk of cardiovascular disease and mortality. Many epidemiologic studies measure a continuous short rhythm strip to ascertain PVCs as a screening tool to identify persons at highest risk. Despite its widespread use in epidemiologic studies, the rhythm strip has not been completely validated. Therefore, a continuous 2-min rhythm strip was measured on 242 consecutive individuals referred for ambulatory ECG monitoring. Prevalence of at least one PVC on the 2-min rhythm strip was compared to a gold standard, the average number of PVCs per hr on ambulatory recording. The prevalence of any PVCs on the 2-min rhythm strip was 19%. As average PVCs per hr increased on the ambulatory ECG recording, sensitivity increased while specificity slowly decreased. Sensitivity ranged from 26-100% and specificity ranged from 81-100% across the distribution of average PVCs per hr on ambulatory monitoring. Area under the receiver operator characteristic (ROC) curve of the 2-min rhythm strip compared to 24-hr results was 0.943. Area under ROC curves were not statistically different (P > 0.05) by age, gender, hypertension status, or history of myocardial infarction. In this clinical population, utilizing the 2-min rhythm strip as an indicator of average PVCs per hr had excellent specificity and moderate to low sensitivity across most of the distribution of average PVCs per hr. The use of a short rhythm strip to detect PVCs may be considered useful in epidemiologic investigations of cardiovascular disease and mortality for detecting high frequency PVCs in populations. The use of a short rhythm strip as a screening tool to detect PVCs in clinical practice is not warranted, based on our findings and the existing literature. However, an awareness that PVCs on a 2-min rhythm strip consistently identify high frequency PVCs on 24-hr recordings should be helpful to clinicians. PMID:10812321

    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.

    Peritoneal dialysis is troubled with declining utilisation as a form of renal replacement therapy in developed countries. We review key aspects of therapy evidenced to have a potential to increase its utilisation. The best evidence to repopulate PD programmes is provided for the positive impact of timely referral and systematic and motivational predialysis education: average odds ratio for instituting peritoneal dialysis versus haemodialysis was 2.6 across several retrospective studies on the impact of predialysis education. Utilisation of PD for unplanned acute dialysis starts facilitated by implantation of peritoneal catheters by interventional nephrologists may diminish the vast predominance of haemodialysis done by central venous catheters for unplanned dialysis start. Assisted peritoneal dialysis can improve accessibility of home based dialysis to elderly, frail, and dependant patients, whose quality of life on replacement therapy may benefit most from dialysis performed at home. Peritoneal dialysis providers should perform close monitoring, preventing measures, and timely prophylactic therapy in patients judged to be prone to EPS development. Each peritoneal dialysis programme should regularly monitor, report, and act on key quality indicators to manifest its ability of constant quality improvement and elevate the confidence of interested patients and financing bodies in the programme.

    Background. Perforation peritonitis is the one of the commonest emergency encountered by surgeons. The aim of this paper is to provide an overview of the spectrum of perforation peritonitis managed in a single unit of a tertiary care hospital in Delhi. Methods. A retrospective study was carried out between May 2010 and June 2013 in a single unit of the department of Surgery, Lok Nayak Hospital, Delhi. It included 400 patients of perforation peritonitis (diffuse or localized) who were studied retrospectively in terms of cause, site of perforation, surgical treatment, complications, and mortality. Only those patients who underwent exploratory laparotomy for management of perforation peritonitis were included. Results. The commonest cause of perforation peritonitis included 179 cases of peptic ulcer disease (150 duodenal ulcers and 29 gastric ulcers) followed by appendicitis (74 cases), typhoid fever (48 cases), tuberculosis (40 cases), and trauma (31). The overall mortality was 7%. Conclusions. Perforation peritonitis in India has a different spectrum as compared to the western countries. Peptic ulcer perforation, perforating appendicitis, typhoid, and tubercular perforations are the major causes of gastrointestinal perforations. Early surgical intervention under the cover of broad spectrum antibiotics preceded by adequate aggressive resuscitation and correction of electrolyte imbalances is imperative for good outcomes minimizing morbidity and mortality.

    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 < 0.05), BMI (R(2) = 0.25, p < 0.05), chronic PD duration (R(2) = 0.64, p < 0.05), episodes of peritonitis (R(2) = 0.93, p < 0.05), D/Pcreatinine (R(2) = 0.76, p < 0.05) and D4/D0glucose (R(2) = 0.81, p < 0.05). No correlation was found between peritoneal thickness and Hb, BP, LVMI and ROD parameters. In conclusion

    We present the case of a 60-year-old Caucasian male with history of hepatitis C viral cirrhosis with portosystemic encephalopathy and ascites with evidence of spontaneous bacterial peritonitis (SBP) with absolute neutrophil count (ANC) of 944 cells/µL blood. Despite adequate treatment, the abdominal pain and elevated creatinine continued to persist. Initial ascites fluid cultures returned back positive for growth of Enterococcus gallinarum. Empiric antibiotics were then substituted with ampicillin/sulbactam. Our case of Enterococcus gallinarum causing SBP is only the seventh case reported in the literature to date. PMID:26064715

    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. PMID:26770971

    The Standardizing Care to improve Outcomes in Pediatric End stage renal disease (SCOPE) Collaborative aims to reduce peritonitis rates in pediatric chronic peritoneal dialysis patients by increasing implementation of standardized care practices. To assess this, monthly care bundle compliance and annualized monthly peritonitis rates were evaluated from 24 SCOPE centers that were participating at collaborative launch and that provided peritonitis rates for the 13 months prior to launch. Changes in bundle compliance were assessed using either a logistic regression model or a generalized linear mixed model. Changes in average annualized peritonitis rates over time were illustrated using the latter model. In the first 36 months of the collaborative, 644 patients with 7977 follow-up encounters were included. The likelihood of compliance with follow-up care practices increased significantly (odds ratio 1.15, 95% confidence interval 1.10, 1.19). Mean monthly peritonitis rates significantly decreased from 0.63 episodes per patient year (95% confidence interval 0.43, 0.92) prelaunch to 0.42 (95% confidence interval 0.31, 0.57) at 36 months postlaunch. A sensitivity analysis confirmed that as mean follow-up compliance increased, peritonitis rates decreased, reaching statistical significance at 80% at which point the prelaunch rate was 42% higher than the rate in the months following achievement of 80% compliance. In its first 3 years, the SCOPE Collaborative has increased the implementation of standardized follow-up care and demonstrated a significant reduction in average monthly peritonitis rates.

    Ambulatory care faces challenges in sustaining a nursing workforce in the future as newly licensed nurses are heavily recruited to inpatient settings and retirements will impact ambulatory care sooner than other areas. Building a diverse team by recruiting nurses of different ages (generations) and skills may result in a more successful and robust organization. Knowledge about generational characteristics and preferences will aid nurse leaders and recruiters in attracting high-quality, talented nurses. Nurses of Generations X and Y can increase their likelihood of success in ambulatory care by better understanding intergenerational issues. PMID:20050492

    This article reviews the concept of day surgery and shows how the treatment can be organized pre-, per- and post-operatively. It can be established in a hospital-integrated unit, a unit separate from the hospital, but connected with it, or a satellite ambulatory facility. Because the patient spends only a short time in hospital it is necessary to have structured preparations before admission, for the benefit of both patient and staff. It should be easy to identify patients suitable for day surgery from the waiting lists, and preparations should be directed at treatment by day surgery right from the start. Rules must be worked out for selecting patients, as well as guidelines for information to patients. It is also necessary to plan the operation programme, and to agree how nurses and doctors should take care of the patient during the different steps of treatment. PMID:8658453

    In 2012 several articles reported interesting findings for the ambulatory practice in internal general medicine. A negative rapid test for influenza does not rule out that diagnosis. A test assessing the walking speed in the elderly can help determining who would benefit from antihypertensive therapy. Antibiotic treatment has no benefit for acute uncomplicated rhinosinusitis and diverticulitis. Probiotics can reduce the risk of post-antibiotic diarrhea. Daily coffee intake could reduce mortality. Oral supplementation of calcium can be harmful to the cardiovascular system. Subclinical hyperthyroidism should be treated to prevent cardiovascular complications. Aspirin can prevent recurrences in case of a primary thromboembolic event. Local injection of corticosteroids under ultrasonographic guidance for plantar fasciitis can be a safe treatment.

The specific job skills, knowledge, and abilities (SKA) that physician executives will need to acquire these competencies were also explored. The Delphi techniques were used to analyze responses from two surveys from members of the American College of Medical Practice Executives. The most important competencies were grouped into 13 management domains, each with specific SKAs. "Managing health care resources to create quality and value" and "fundamentals of business and finance" were rated as the most important competencies. The most frequently rated SKA was the "ability to build and maintain credibility and trust." PMID:10185642

    Peritoneal implants were fabricated from poly 2-OH, ethyl methacrylate (HEMA), polyetherurethane (polytetramethylene glycol 1000 MW, 1,4 methylene disocynate, and ethyl diamine), and untreated and sputter treated polytetrafluoroethylene (PTFE). The sputter treated PTFE implants were produced by an 8 cm diameter argon ion source. The treated samples consisted of ion beam sputter polished samples, sputter etched samples (to produce a microscopic surface cone texture) and surface pitted samples (produced by ion beam sputtering to result in 50 microns wide by 100 microns deep square pits). These materials were implanted in rats for periods ranging from 30 minutes to 14 days. The results were evaluated with regard to cell type and attachment kinetics onto the different materials. Scanning electron microscopy and histological sections were also evaluated. In general the smooth hydrophobic surfaces attracted less cells than the ion etched PTFE or the HEMA samples. The ion etching was observed to enhance cell attachment, multinucleated giant cell (MNGC) formation, cell to cell contact, and fibrous capsule formation. The cell responsed in the case of ion etched PTFE to an altered surface morphology. However, equally interesting was the similar attachment kinetics of HEMA verses the ion etched PTFE. However, HEMA resulted in a markedly different response with no MNGC's formation, minimal to no capsule formation, and sample coverage by a uniform cell layer.

    Compliance in peritoneal dialysis is reported as being a significant problem. In CAPD, the percentage of non-compliant patients varies between 10 and 40%. In APD the phenomenon seems to be more limited, at 15% - 20%. We considered 23 patients who had been on APD for more than 3 months.The dialytic treatment was performed using the Home Choice Pro device to record all the parameters of the dialysis session. The last 30 days of treatment were considered in the assessment of compliance, evaluating differences in daytime and night-time volumes between the prescription and the actual treatment,the length of the night-time session, and the days of treatment. As regards volume and duration, no differences were found compared to the dialytic prescriptions. For the days of treatment, a differencewas onlyfound in 3 patients: 2 self-administered patients missed day of therapy out of 30, and in both cases the missed tretment was ageed with the Centre; non-compliance was only found in 1 patient (4,3%), whose treatment was performed by the family, and who missed 4 days out of 30.

    Ambulatory health care needs within the United States are served by a wide range of hospitals, clinics, and private practices. The Emergency Department (ED) functions as an important point of supply for ambulatory healthcare services. Growth in our aging populations as well as changes stemming from broader healthcare reform are expected to continue trend in congestion and increasing demand for ED services. While congestion is, in part, a manifestation of unmatched demand, the state of the alignment between the demand for, and supply of, emergency department services affects quality of care and profitability. The central focus of this research is to provide an explanation of the salient factors at play within the dynamic demand-supply tensions within which ambulatory care is provided within an Emergency Department. A System Dynamics (SO) simulation model is used to capture the complexities among the intricate balance and conditional effects at play within the demand-supply emergency department environment. Conceptual clarification of the forces driving the elements within the system , quantifying these elements, and empirically capturing the interaction among these elements provides actionable knowledge for operational and strategic decision-making.

    Continuous peripheral nerve blocks (CPNB) are commonly used for intraoperative and postoperative analgesia. Our study aimed at describing our experience with ambulatory peripheral nerve catheters. After Institutional Review Board approval, records for all patients discharged with supraclavicular or popliteal catheters between January 1, 2009 and December 31, 2011 were reviewed. A licensed practitioner provided verbal and written instructions to the patients prior to discharge. Daily follow-up phone calls were conducted. Patients either removed their catheters at home with real-time simultaneous telephone guidance by a member of the Acute Pain Service or had them removed by the surgeon during a regular office visit. The primary outcome of this analysis was the incidence of complications, categorized as pharmacologic, infectious, or other. The secondary outcome measure was the average daily pain score. Our study included a total of 1059 patients with ambulatory catheters (769 supraclavicular, 290 popliteal). The median infusion duration was 5 days for both groups. Forty-two possible complications were identified: 13 infectious, 23 pharmacologic, and 6 labeled as other. Two patients had retained catheters, 2 had catheter leakage, and 2 had shortness of breath. Our study showed that prolonged use of ambulatory catheters for a median period of 5 days did not lead to an increased incidence of complications. PMID:25535627

    2008-01-01

    The Maryland Health Services Cost Review Commission (HSCRC or the commission) is a government agency with the authority to establish rates for both inpatient and outpatient services for all general acute care hospitals in the state. By law and consistent with the state's unique Medicare waiver, all payers (including Medicare and Medicaid) must pay hospitals on the basis of these rates. The HSCRC has used diagnosis related groups to set case-mix-adjusted limits on the revenue per discharge for inpatient services (similar to Medicare inpatient prospective payment nationally) yet, the Maryland rate-setting system for outpatient services has not embodied incentives to control utilization of services. Beginning in the state's fiscal year 2008, the HSCRC is implementing regulation of ambulatory surgery services using ambulatory patient groups to provide better incentives to control utilization, and to facilitate comparisons of the case-mix-adjusted charges per ambulatory surgery case across hospitals. Maryland has been an innovator in the design and successful implementation of payment systems and other incentive mechanisms to constrain hospital cost, maintain payment equity, and ensure access to needed hospital care. The HSCRC's adoption of all patient refined diagnosis related groups and the hospital-specific relative value method for establishing diagnosis related group weights in 2005 was relevant to the Centers for Medicare and Medicaid Services' decision to move to Medicare severity diagnosis related groups beginning in federal fiscal year 2008, and to consider the use of hospital-specific relative value weights. The HSCRC's decision to use ambulatory patient groups for ambulatory surgery is an attempt to apply the most effective features of inpatient payment systems, prospective payment, including incentives to control service volumes. As such, it represents a radical departure from prevailing payment arrangements in that it seeks to remove the traditional

    This article describes a new case-mix methodology applicable primarily to the ambulatory care sector. The Ambulatory Care Group (ACG) system provides a conceptually simple, statistically valid, and clinically relevant measure useful in predicting the utilization of ambulatory health services within a particular population group. ACGs are based on a person's demographic characteristics and their pattern of disease over an extended period of time, such as a year. Specifically, the ACG system is driven by a person's age, sex, and ICD-9-CM diagnoses assigned during patient-provider encounters; it does not require any special data beyond those collected routinely by insurance claims systems or encounter forms. The categorization scheme does not depend on the presence of specific diagnoses that may change over time; rather it is based on broad clusters of diagnoses and conditions. The presence or absence of each disease cluster, along with age and sex, are used to classify a person into one of 51 ACG categories. The ACG system has been developed and tested using computerized encounter and claims data from more than 160,000 continuous enrollees at four large HMOs and a state's Medicaid program. The ACG system can explain more than 50% of the variance in ambulatory resource use if used retrospectively and more than 20% if applied prospectively. This compares with 6% when age and sex alone are used. In addition to describing ACG development and validation, this article also explores some potential applications of the system for provider payment, quality assurance, utilization review, and health services research, particularly as it relates to capitated settings.

    ♦ Objectives: The present study evaluated the tool used to assess patients’ skills and the impact on peritonitis rates of a new multidisciplinary peritoneal dialysis (PD) education program (PDEP). ♦ Methods: After the University Hospital Ethics Committee approved the study, the educational and clinical records of PD patients were retrospectively analyzed in two phases. In phase I, an Objective Structured Assessment (OSA) was used during August 2008 to evaluate the practical skills of 25 patients with adequate Kt/V and no mental disabilities who had been on PD for more than 1 month. Test results were correlated with the prior year’s peritonitis rate. In phase II, the new PDEP, consisting of individual lessons, a retraining schedule, and group meetings, was introduced starting 1 September 2008. Age, sex, years of education, time on PD, number of training sessions, and peritonitis episodes were recorded. Statistical analyses used t-tests, chi-square tests, and Poisson distributions; a p value of less than 0.05 was considered significant. ♦ Results: In phase I, 25 patients [16 men, 9 women; mean age: 54 ± 15 years (range: 22 - 84 years); mean time on PD: 35 ± 30 months (range: 1 - 107 months)] were studied. The OSA results correlated with peritonitis rates: patients who passed the test had experienced significantly lower peritonitis rates during the prior year (p < 0.05). In phase II, after the new PDEP was introduced, overall peritonitis rates significantly declined (to 0.28 episodes/patient-year from 0.55 episodes/patient-year, p < 0.05); the Staphylococcus peritonitis rate also declined (to 0.09 episodes/patient-year from 0.24 episodes/patient-year, p < 0.05). ♦ Conclusions: The OSA is a reliable tool for assessing patients’ skills, and it correlates with peritonitis rates. The multidisciplinary PDEP significantly improved outcomes by further lowering peritonitis rates. PMID:22753455

    Mesothelial-to-mesenchymal transition (MMT) is an auto-regulated physiological process of tissue repair that in uncontrolled conditions such as peritoneal dialysis (PD) can lead to peritoneal fibrosis. The maximum expression of peritoneal fibrosis induced by PD fluids and other peritoneal processes is the encapsulating peritoneal sclerosis (EPS) for which no specific treatment exists. Tamoxifen, a synthetic estrogen, has successfully been used to treat retroperitoneal fibrosis and EPS associated with PD. Hence, we used in vitro and animal model approaches to evaluate the efficacy of Tamoxifen to inhibit the MMT as a trigger of peritoneal fibrosis. In vitro studies were carried out using omentum-derived mesothelial cells (MCs) and effluent-derived MCs. Tamoxifen blocked the MMT induced by transforming growth factor (TGF)-β1, as it preserved the expression of E-cadherin and reduced the expression of mesenchymal-associated molecules such as snail, fibronectin, collagen-I, α-smooth muscle actin, and matrix metalloproteinse-2. Tamoxifen-treatment preserved the fibrinolytic capacity of MCs treated with TGF-β1 and decreased their migration capacity. Tamoxifen did not reverse the MMT of non-epitheliod MCs from effluents, but it reduced the expression of some mesenchymal molecules. In mice PD model, we demonstrated that MMT progressed in parallel with peritoneal membrane thickness. In addition, we observed that Tamoxifen significantly reduced peritoneal thickness, angiogenesis, invasion of the compact zone by mesenchymal MCs and improved peritoneal function. Tamoxifen also reduced the effluent levels of vascular endothelial growth factor and leptin. These results demonstrate that Tamoxifen is a therapeutic option to treat peritoneal fibrosis, and that its protective effect is mediated via modulation of the MMT process. PMID:23637793

In contrast to the previous version, the revised catalogue contains additional non-operative procedures. Some procedures may be provided either in an ambulatory or inpatient setting. However, for the hospitals it is of particular importance that some specified procedures should be performed on an ambulatory basis. If these particular services are delivered in an inpatient setting at least one stipulated criteria of exception has to be fulfilled.

    This report presents two cases of young males who developed the rare idiopathic form of sclerosing encapsulating peritonitis (SEP) presented as partial bowel obstruction, both diagnosed during surgical treatment, with satisfactory outcomes. Sclerosing encapsulating peritonitis is a rare and enigmatic condition, characterized by intraperitoneal fibrosclerosis, which causes intestinal obstruction. It is a chronic entity with a poorly elucidated pathophysiology, leading to the constitution of a thick white nacreous fibrosis membrane that wraps the bowel in a concertina-like fashion with some adhesions configuring an intra-abdominal cocoon. Sclerosing encapsulating peritonitis is reported in a wide variety of patients, including those who have undergone peritoneal dialysis, young adolescent girls, cirrhotic patients after peritoneal-venous shunting, and patients treated with β-blockers. Nevertheless, the etiology of SEP remains obscure. This entity presents many difficulties in preoperative diagnosis because of its peculiar characteristics. Recognition of the SEP results in proper management and prevents unnecessary bowel resection. Regardless of cause, the treatment of the obstruction is surgical, with dissection of the encasing membrane from the intestine and separation of adherent loops of small bowel until they are laid free and returned to their normal configuration. The prognosis after appropriate surgical therapy is good, but depends on coexisting diseases. PMID:21969199

    We report a case of acute chylous ascites formation presenting as peritonitis (acute chylous peritonitis) in a patient suffering from acute pancreatitis due to hypertriglyceridemia and alcohol abuse. The development of chylous ascites is usually a chronic process mostly involving malignancy, trauma or surgery, and symptoms arise as a result of progressive abdominal distention. However, when accumulation of "chyle" occurs rapidly, the patient may present with signs of peritonitis. Preoperative diagnosis is difficult since the clinical picture usually suggests hollow organ perforation, appendicitis or visceral ischemia. Less than 100 cases of acute chylous peritonitis have been reported. Pancreatitis is a rare cause of chyloperitoneum and in almost all of the cases chylous ascites is discovered some days (or even weeks) after the onset of symptoms of pancreatitis. This is the second case in the literature where the patient presented with acute chylous peritonitis due to acute pancreatitis, and the presence of chyle within the abdominal cavity was discovered simultaneously with the establishment of the diagnosis of pancreatitis. The patient underwent an exploratory laparotomy for suspected perforated duodenal ulcer, since, due to hypertriglyceridemia, serum amylase values appeared within the normal range. Moreover, abdominal computed tomography imaging was not diagnostic for pancreatitis. Following abdominal lavage and drainage, the patient was successfully treated with total parenteral nutrition and octreotide. PMID:22563182

    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

    The principles of 'lean management' have permeated many sectors of today's business world, secondary to the success of the Toyota Production System. This management method enables workers to eliminate mistakes, reduce delays, lower costs, and improve the overall quality of the product or service they deliver. These lean management principles can be applied to health care. Their implementation within the ambulatory care setting is predicated on the continuous identification and elimination of waste within the process. The key concepts of flow time, inventory and throughput are utilized to improve the flow of patients through the clinic, and to identify points that slow this process -- so-called bottlenecks. Nonessential activities are shifted away from bottlenecks (i.e. the physician), and extra work capacity is generated from existing resources, rather than being added. The additional work capacity facilitates a more efficient response to variability, which in turn results in cost savings, more time for the physician to interact with patients, and faster completion of patient visits. Finally, application of the lean management principle of 'just-in-time' management can eliminate excess clinic inventory, better synchronize office supply with patient demand, and reduce costs.

    Continuous monitoring of respiratory rate in ambulatory conditions has widespread applications for screening of respiratory diseases and remote patient monitoring. Unfortunately, minimally obtrusive techniques often suffer from low accuracy. In this paper, we describe an algorithm with low computational complexity for combining multiple respiratory measurements to estimate breathing rate from an unobtrusive chest patch sensor. Respiratory rates derived from the respiratory sinus arrhythmia (RSA) and modulation of the QRS amplitude of electrocardiography (ECG) are combined with a respiratory rate derived from tri-axial accelerometer data. The three respiration rates are combined by a weighted average using weights based on quality metrics for each signal. The algorithm was evaluated on 15 elderly subjects who performed spontaneous and metronome breathing as well as a variety of activities of daily living (ADLs). When compared to a reference device, the mean absolute error was 1.02 breaths per minute (BrPM) during metronome breathing, 1.67 BrPM during spontaneous breathing, and 2.03 BrPM during ADLs.

    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

    Streptomyces organisms are soil inhabitants rarely causing nonmycetomic infections. We describe a case of secondary peritonitis caused by Streptomyces viridis in a chronic alcoholic patient who presented with fever, abdominal distension, and pain in the abdomen. The most likely source of infection was by inoculation through multiple paracenteses, done for treatment of ascites, before the patient came to our health care center. This is the second case report of Streptomyces peritonitis and the first case caused by Streptomyces viridis, which is usually found in the soil in our geographic region. PMID:22337982

    Primary peritonitis is a rare condition occurring, by definition, in patients without underlying causes, such as perforated viscus, pre-existing ascites, or nephrosis. We report a case of primary peritonitis and shock due to group A beta-hemolytic streptococcus, a rare etiology. A review of the world's literature shows a predilection for women to have this condition. The entry site is obscure in most cases. Asymptomatic genital tract colonization may be a portal of entry in some women. Shock or toxic shock syndrome often accompany the abdominal findings. Laparotomy to exclude a perforated viscus may be unavoidable. Despite the significant morbidity, expeditious and appropriate antibiotic therapy is curative. PMID:10777203

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

    Examination of blood serum and cellular elements of 45 patients with postoperative diffuse purulent peritonitis shows that in the majority of examined persons before and in the first days after the operation immunodepression exists. The dynamics of immunologic disturbances (antibody titers, phagocytosis, immunoglobulines, T- and B-lymphocytes) are sufficiently informative and as a rule, correlate with clinical course of peritonitis. Adequate reaction of the organism to infection resulted in a favourable outcome. Low values of immunologic indices in postoperative period necessitate the use of stimulant therapy in combined treatment of this complication. PMID:9916429

    Urinary peritonitis (the uroperitoneum) is categorized as a difficult to diagnose clinical entity due to its poor manifestations. Vesical trauma following pelvis bone fracture is the most frequently involved in the uroperitoneum aetiology, followed by spontaneous vesical rupture and intraoperative iatrogenic lesions. One of the most important and constant signs that can occur is diffuse abdominal tension, without tenderness. The imagistic procedure that sets the diagnosis is retrograde cystography showing intraperitoneal urine effusion. Vesical rupture is a surgical emergency. The uroperitoneum is a particular type of peritonitis that has hidden and misleading symptoms which can delay the diagnosis long enough to endanger the patient's life. PMID:20108482

    The ventriculoperitoneal (VP) shunt is a common procedure in pediatric neurosurgery that carries a risk of complications at cranial and abdominal sites. We report on the case of a child with shunt infection and malfunction. The peritoneal catheter was tethered within the abdominal cavity, precluding its removal. Subsequently, laparoscopic exploration identified a knot at the distal end of the peritoneal catheter around the omentum. A new VP shunt was inserted after the infection was healed. This type of complication occurs rarely, so there are a limited number of case reports in the literature. This report is complemented by a literature review. PMID:24109528

    This conference serves to further the state of the art in the application of computers to medical care via a forum for the intercommunication of ideas. Papers discuss the experiences of diverse research projects. It is the purpose of this article to review the major developments in ambulatory care decision support. From this vantage point, the major impediments to broad applicability of information systems are discussed. The DUCHESS Medical Information Management System is then described as a step towards overcoming these obstacles. Two distinct but often overlapping issues are the representation of the data and its subsequent manipulation: records vs. knowledge. The complexity of the medical record requires state-of-the-art computer science. Clinical decision support requires flexible means for representing medical knowledge and the ability to input “rules.” Artificial intelligence has provided tools for simulating the decision making processes. A sample of the major systems are contrasted and compared. In the realm of medical records COSTAR, TMR, SCAMP, HELP, and STOR are considered. In clinical decision support CADEUCUS, REGENSTRIEF, PKC, and DUCHESS are reviewed.

    The objective of the study is to investigate ambulatory blood pressure monitoring (ABPM) in a sample of Spanish nonagenarians. We also analyzed the misdiagnosis of hypertension and investigated blood pressure (BP) control in treated hypertensive nonagenarians. Twenty-four-hour ABPM was undertaken in a group of 42 nonagenarians. The 24-h mean, daytime BP, nighttime BP and heart rate (HR) were extracted from the ABPM. Sociodemographic data, the ability to perform basic daily activities, measured by the Barthel index (BI) or instrumental activities revealed by the Lawton and Brody index (LI), cognition, and comorbidity were evaluated. Thirty-one subjects were receiving antihypertensive drug treatment. Twenty-four hour, daytime and sleeping pressures averaged 130/65, 131/68 and 128/63mmHg, respectively. Seventeen (40.5%) of the 42 patients had a daytime BP of 135/85 or higher. In terms of the BP pattern, 8 (19%) subjects were dippers, 19 (45%) non-dippers, and 15 (36%) were risers. Five (45.46%) out of 11 patients with no evidence of hypertension (normotensive patients) had a daytime BP of 135/85 or higher. The mean daytime BP was 135/85 or higher in 12 (38.7%) out of 31 nonagenarians who had previously received therapy for hypertension. In, conclusion a high prevalence of hypertension, misdiagnosis and inadequate BP control was found in nonagenarians treated for hypertension. PMID:18423650

    The principles of electromyographic (EMG) analysis can be divided into the following groups: signal or motor unit shape analysis, amplitude analysis, multi-channel or successive time difference analysis, signal frequency composition analysis, change of frequency time based analysis based on simultaneous amplitude or frequency based analysis or concentric and excentric work based shape and amplitude ratio analysis. The aim of this paper is to present an ambulatory portable device for surface EMG analysing both for integrated EMG and for spectral analysis. The reliability of surface EMG recordings have established. The recent new technology gets a possibility to measure by reliable way surface EMG on-line during exercise, rehabilitation or occupational conditions. Portable EMG measurement unit and analysing program seems to be suitable for documentation of the response of rehabilitation programs, effects of physiotherapy, analysing the muscle balance and activity of sportsman and for documentation of occupational health problems. Automatic interpretation and wide data base for patient data makes the system useful in daily practice. PMID:9607100

    OBJECTIVE To identify surgical site infection (SSI) rates following pediatric ambulatory surgery, SSI outcomes and risk factors, and sensitivity and specificity of SSI administrative billing codes. DESIGN Retrospective chart review of pediatric ambulatory surgeries with International Classification of Disease, Ninth Revision (ICD-9) codes for SSI, and a systematic random sampling of 5% of surgeries without SSI ICD-9 codes, all adjudicated for SSI on the basis of an ambulatory-adapted National Healthcare Safety Network definition. SETTING Urban pediatric tertiary care center April 1, 2009-March 31, 2014. METHODS SSI rates and sensitivity and specificity of ICD-9 codes were estimated using sampling design, and risk factors were analyzed in case-rest of cohort, and case-control, designs. RESULTS In 15,448 pediatric ambulatory surgeries, 34 patients had ICD-9 codes for SSI and 25 met the adapted National Healthcare Safety Network criteria. One additional SSI was identified with systematic random sampling. The SSI rate following pediatric ambulatory surgery was 2.9 per 1,000 surgeries (95% CI, 1.2-6.9). Otolaryngology surgeries demonstrated significantly lower SSI rates compared with endocrine (P=.001), integumentary (P=.001), male genital (P<.0001), and respiratory (P=.01) surgeries. Almost half of patients with an SSI were admitted, 88% received antibiotics, and 15% returned to the operating room. No risk factors were associated with SSI. The sensitivity of ICD-9 codes for SSI following ambulatory surgery was 55.31% (95% CI, 12.69%-91.33%) and specificity was 99.94% (99.89%-99.97%). CONCLUSIONS SSI following pediatric ambulatory surgery occurs at an appreciable rate and conveys morbidity on children. Infect Control Hosp Epidemiol 2016;37:931-938. PMID:27121727

    Background: Peritoneal tuberculosis accounts 1-2% of all forms of tuberculosis. Peritoneal tuberculosis is an important differential diagnosis for ovarian cancer in women with ascites, adnexal mass and elevated cancer antigen 125 (CA125) levels. We report a case of a 32- year -old woman with multiple miliary peritoneal deposits mimicking advanced ovarian carcinoma. Case Presentation: A 32-year-old drug addicted woman presented with menometrorrhagia, fever and shivering, ascites and pelvis mass. Ultrasonography revealed a 53×65 mm cyst in left ovary and ascites. Multiple miliary peritoneal deposits were observed during laparatomy without any mass, histologic examination confirmed tuberculosis of uterus, tubes, omentum, liver and external surfaces of small intestine. Finally, the patient recovered with anti-tuberculosis treatment. Conclusion: These findings highlight considering tuberculosis in the differential diagnosis of any patients with adnexal mass, ascitis and elevated serum CA125 even with negative cytology and bacteriology test results.

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

    PubMed Central

    Yung, Susan; Chan, Tak Mao

    2011-01-01

    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. PMID:22203782

    Nocardia asteroides is a rare pathogen in peritoneal dialysis-related peritonitis. We report on a 13-year-old female with Nocardia asteroides peritonitis complicated by an intra-abdominal abscess. Linezolid was administered intravenously for 3 months and followed by oral therapy for an additional 5 months with close monitoring for adverse effects. The patient was discharged after 3 months of hospitalization on hemodialysis. The diagnosis and management of such cases can be problematic due to the slow growth and difficulty of identifying Nocardia species. The optimal duration of treatment for Nocardia peritonitis is not known. Linezolid can be used for prolonged periods in cases of trimethoprim/sulfamethoxazole-resistant cases with close monitoring for adverse effects. PMID:26768669

    We have studied the effectiveness of pharmacologic prophylaxis of experimental peritoneal hydatidosis. Mice (n = 140, divided in ten groups) suffered intraperitoneal contamination with protoscoleces of E. granulosus from sheep. Each group received different treatment (mebendazole, praziquantel, or both), in three different schedules (during 3 days before contamination, during 7 days after contamination, or both before and after Mebendazole 150 mg/kg-day), praziquantel (25 mg/kg-day) were given in three daily doses. Mice were sacrificed six months later and the number and type of existing peritoneal cysts was recorded. Prophylaxis prior to contamination was shown ineffective. Early treatment greatly decreased the severity of the peritoneal hydatidosis. The administration of the drug before and after contamination, did not improve the results obtained when the drug was given after contamination. Both mebendazole and praziquantel were effective, though the former obtained better results. The association of both drugs does not improve the results obtained with mebendazole alone. These experimental results recommend the early use of mebendazol or praziquantel after open surgery for hydatidosis, in order to prevent the occurrence of secondary peritoneal hydatidosis.

    2007-01-01

    Exit-site infection (ESI), tunnel infection and associated peritonitis are major causes of morbidity and catheter loss in chronic peritoneal dialysis patients. Meticulous exit-site care is vital in preventing ESI. Avoiding trauma to the exit-site and daily cleaning of the exit-site with a dedicated antimicrobial soap is essential for the longevity of the peritoneal dialysis catheter. Antibiotics cream and disinfectant agents including povidone-iodine, chlorhexidine, electrolytic chloroxidizing solutions (Amuchina 10% - ExSept Plus, Amuchina 5% - ExSept) are useful to keep the resident micro-organisms inhibited. ESI rates in peritoneal dialysis patients treated with Amuchina 10% (ExSept Plus) and Amuchina 5% (ExSept) for the exit-site care are similar or lower compared to povidone-iodine or chlorhexidine. Electrolytic chloroxidizing (Amuchina 10% - ExSept Plus and Amuchina 5% - ExSept) solutions for exit-site care are effective for prevention and treatment of ESI. PMID:17099306

    A paradigm shift has recently occurred in the clinical management of peritoneal surface malignancies (PSM). Once regarded as end-stage disseminated conditions only to be palliated, PSM are now increasingly recognized as local-regional disease entities amenable to potentially curative therapies. Better knowledge of the natural history and patterns of disease-progression has evolved into a novel treatment approach combining aggressive cytoreductive surgery (CRS) and perioperative intraperitoneal chemotherapy, to treat the microscopic residual disease. Such a complex comprehensive treatment has reportedly resulted in a survival improvement over historical controls, and it is gaining an increasing acceptance as standard of care for selected patients with peritoneal metastases from gastrointestinal and gynecological tumor and rare primary peritoneal malignancies. This article addresses the rational bases supporting the comprehensive treatment of PSM. The biology and patho-physiology of peritoneal tumor dissemination, with their implication on surgical and local-regional management are reviewed. The cytoreductive surgical procedures and intraperitoneal chemotherapy administration techniques are described, together with the theoretical principles from which have originated. The main controversial issues in the operative management of PSM are discussed, focusing on the technical variants adopted in our institution. The most recent literature data on both patient selection and appropriate indications for combined treatment are presented. Additionally, a brief overview of treatment results and long-term outcomes following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) in the different PSM is provided.

    Peritoneal dialysis is an equally valuable method for some patients. It is a method with some advantages and thus should be considered the method of choice. Are the trends of treatment with this method instead of terminal kidney disease replacement stagnating? In our ten-year retrospective study, we tried to do assess how to control the efficiency of dialysis and what was its influence on patient survival. We compared clinical state of patients, laboratory indicators of dialysis dosage (Kt/v) and peritoneal membrane transport function (PET). Patients were divided according to Kt/v values <1.7, 1.7-2.2 and >2.2. According to PET findings, they were divided into four standard groups. Kt/v and PET are unavoidable evaluation factors of peritoneal membrane and for prescribing dialysis. The transport, ultrafiltration and other membrane characteristics change with time and with inflammatory processes. On any calculation of adequacy, it is essential to distinguish diuretic and anuric patients. The adequacy of peritoneal dialysis should be incorporated in the conclusion on prescriptions and quality treatment of each individual patient. PMID:23441537

    BACKGROUND: Pasteurella species are Gram-negative coccobacilli that are a part of the normal oropharyngeal flora of numerous domestic animals. They have been recognized as a rare but significant cause of peritonitis in patients undergoing peritoneal dialysis (PD). A consensus about management strategies for PD-associated peritonitis caused by Pasteurella species currently does not exist. METHODS: The microbiological database serving the Manitoba Renal Program was searched from 1997 to 2013 for cases of Pasteurella species PD-associated peritonitis, and charts were reviewed. PubMed was searched for case reports and data were abstracted. RESULTS: Seven new local cases and 30 previously reported cases were analyzed. This infection is clinically similar to other forms of PD peritonitis, with household pet exposure appearing to be the strongest risk factor. Cats are the most commonly implicated pet. Direct contact between the pet and the equipment was commonly reported (25 of 37 patients) but was not necessary for infection to develop. The mean duration of treatment was 15 days. Complication rates were low, with only 11% of patients requiring PD catheter removal. There was no mortality reported. CONCLUSION: Pasteurella species are a rare cause of PD-associated peritonitis that can be successfully treated with a two-week course of intraperitoneal antibiotics with a high likelihood of catheter salvage.

  13. Peritoneal adhesions after laparoscopic gastrointestinal surgery

    Although laparoscopy has the potential to reduce peritoneal trauma and post-operative peritoneal adhesion formation, only one randomized controlled trial and a few comparative retrospective clinical studies have addressed this issue. Laparoscopy reduces de novo adhesion formation but has no efficacy in reducing adhesion reformation after adhesiolysis. Moreover, several studies have suggested that the reduction of de novo post-operative adhesions does not seem to have a significant clinical impact. Experimental data in animal models have suggested that CO2 pneumoperitoneum can cause acute peritoneal inflammation during laparoscopy depending on the insufflation pressure and the surgery duration. Broad peritoneal cavity protection by the insufflation of a low-temperature humidified gas mixture of CO2, N2O and O2 seems to represent the best approach for reducing peritoneal inflammation due to pneumoperitoneum. However, these experimental data have not had a significant impact on the modification of laparoscopic instrumentation. In contrast, surgeons should train themselves to perform laparoscopy quickly, and they should complete their learning curves before testing chemical anti-adhesive agents and anti-adhesion barriers. Chemical anti-adhesive agents have the potential to exert broad peritoneal cavity protection against adhesion formation, but when these agents are used alone, the concentrations needed to prevent adhesions are too high and could cause major post-operative side effects. Anti-adhesion barriers have been used mainly in open surgery, but some clinical data from laparoscopic surgeries are already available. Sprays, gels, and fluid barriers are easier to apply in laparoscopic surgery than solid barriers. Results have been encouraging with solid barriers, spray barriers, and gel barriers, but they have been ambiguous with fluid barriers. Moreover, when barriers have been used alone, the maximum protection against adhesion formation has been no greater than

    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: <1 year, 4.8%; 1 to <2 years, 9.2%; 2 to <4 years, 16.3%; 4 to <8 years, 32.0%; and ≥8 years, 47.5%. The percentage of PD patients who completely manually exchanged the dialysate was 29.8%. The percentages of PD patients who used a double-bag exchange system with ultraviolet-light irradiation and those who used the same system but with a sterile connecting device were 54.7 and 13.9%, respectively. The percentage of patients on PD for <1 year using an APD machine was 43.4%, and it decreased with a PD vintage of ≥2 years. The mean rate of peritonitis was 0.22 per patient

    Tumor invasion to the peritoneum is a poor prognostic factor in cancer patients. Accurate diagnosis of disseminated peritoneal tumors is essential to accurate cancer staging. To date, peritoneal washing cytology during laparotomy has been used for diagnosis of peritoneal dissemination of gastrointestinal cancer, but its sensitivity has not been satisfactory. Thus, a more direct approach is indispensable to detect peritoneal dissemination in vivo. Fluorescein diacrylate (FDAcr) is an esterase-sensitive fluorescent probe derived from fluorescein. In cancer cells, fluorescent fluorescein generated by exogenous application of FDAcr selectively deposits owing to its stronger hydrolytic enzyme activity and its lower leakage rate. We examined whether FDAcr can specifically detect disseminated peritoneal tumors in athymic nude mouse models. Intraperitoneally administered FDAcr revealed disseminated peritoneal microscopic tumors not readily recognized on white-light imaging. These results suggest that FDAcr is a useful probe for detecting disseminated peritoneal tumors.

    AIM: To evaluate the demographic and clinical parameters affecting the outcomes of ambulatory laparoscopic cholecystectomy (ALC) in terms of pain, nausea, anxiety level, and satisfaction of patients in a tertiary health center. MATERIALS AND METHODS: ALC was offered to 60 patients who met the inclusion criteria. Follow-up (questioning for postoperative pain or discomfort, nausea or vomiting, overall satisfaction) was done by telephone contact on the same day at 22:00 p.m. and the first day after surgery at 8: 00 a.m. and by clinical examination one week after operation. STAI I and II data were used for proceeding to the level of anxiety of patients before and/or after the operation. RESULTS: Sixty consecutive patients, with a mean age of 40.6 ± 8.1 years underwent ALC. Fifty-five (92%) patients could be sent to their homes on the same day but five patients could not be sent due to anxiety, pain, or social indications. Nausea was reported in four (6.7%) cases and not associated with any demographic or clinical features of patients. On the other hand, pain has been reported in 28 (46.7%) cases, and obesity and shorter duration of gallbladder disease were associated with the increased pain perception (P = 0.009 and 0.004, respectively). Preopereative anxiety level was significantly higher among patients who could not complete the ALC procedure (P = 0.018). CONCLUSION: Correct management of these possible adverse effects results in the increased satisfaction of patients and may encourage this more cost-effective and safe method of laparoscopic cholecystectomy.

    1993-01-01

    Previous use of the MIT/BIH arrhythmia database, on analog tape, to investigate compression of ambulatory ECG data by average beat subtraction, residual differencing, and Huffman coding of the residuals had shown that with a quantization level of 35 mu V and a sample rate of 100 samples per second, it was possible to store ECG data with average data rates of 174 bits per second (bps), but because of the variation in ECG signals, data rates for different records ranged from 144 bps to 230 bps. In a practical storage system, it is desirable to fix the maximum data rate and store data with a minimum of distortion. For this study the previous compression algorithm was modified to adapt its quantization level to different ECG signal conditions. Two adaptation strategies were investigated. Both adapt the quantization-step size according to the number of bytes required for storing the coded signal, beat arrival times, and beat classifications. The new compression algorithm was tested with data from the MIT/BIH database on CD ROM. With the more successful of the two strategies, the adaptive compression algorithm stored MIT/BIH records with a difference of only 0.8 bps between the record with the highest data rate and the record with the lowest data rate. The average data rate for the entire database was 193.3 bps. Signal-to-compression noise ratios varied from record to record and varied over time for a given record. Average signal to compression noise ratios varied from 26.82 to 532.83. PMID:8418967

    Psychosomatic disorders are comprised of an array of psychological, biological, and environmental features. The existing evidence points to a role for genetic factors in explaining individual differences in the development and maintenance of a variety of disorders, but studies to date have not shown consistent and replicable effects. As such, the attempt to uncover individual differences in the expression of psychosomatic disorders as a function of genetic architecture requires careful attention to their phenotypic architecture, or the various intermediate phenotypes that make up a heterogeneous disorder. Ambulatory monitoring offers a novel approach to measuring time-variant and situation-dependent intermediate phenotypes. Recent examples of the use of ambulatory monitoring in genetic studies of stress reactivity, chronic pain, alcohol use disorders, and psychosocial resilience are reviewed in an effort to highlight the benefits of ambulatory monitoring for genetic study designs.

    To compare ambulatory preceptors' and students' perceptions of the use of educational planning (setting goals, assessing needs, formulating objectives, choosing methods, and providing feedback and evaluation) in the office setting, we mailed a survey, which was returned by 127 longitudinal ambulatory preceptors and 168 first-year and second-year medical students. Faculty perceptions did not match student perceptions of what occurred in the longitudinal preceptor program teaching sessions in educational planning areas. Students perceived these activities were occurring with much less frequency than faculty perceived. Medical education needs to move beyond the usual faculty development workshop paradigm to a more comprehensive educational development model that includes training both faculty and students in core educational skills. This will enable the ambulatory setting to reach its full educational potential in training future physicians. PMID:10203628

    Purpose. The aim of this study is to show you the results we obtained through the integration of the Urology Department into the Ambulatory Surgery Unit for the very first twelve years. Scope. We will explain both the criteria we followed for patients to join in and the surgical and anesthetic procedures we used with those 1544 patients who were ambulatory subjected to urological diseases. After those patients were treated, they reached up to 95% of reasonable results. Conclusions. Most of urological patients liable to have surgical treatment are bound to be included in an ambulatory surgery program, which implies neither a worse healthcare service standard nor a worse satisfaction in patients.

    The current climate in the health care industry demands efficiency and patient satisfaction in medical care delivery. These two demands intersect in scheduling of ambulatory care visits. This paper uses patient and doctor-related measures to assess ambulatory care performance and investigates the interactions among appointment system elements and patient panel characteristics. Analysis methodology involves simulation modeling of clinic sessions where empirical data forms the basis of model design and assumptions. Results indicate that patient sequencing has a greater effect on ambulatory care performance than the choice of an appointment rule, and that panel characteristics such as walk-ins, no-shows, punctuality and overall session volume, influence the effectiveness of appointment systems.

    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

  3. The role of ambulatory blood pressure monitoring in clinical practice.

    1997-09-01

    The introduction of noninvasive techniques for the repetitive measurement of blood pressure in ambulant subjects has permitted improved precision in the assessment of hypertension during normal daily life. The traditional clinic (or "office") method of blood pressure measurement has the advantages of simplicity and low cost, and forms the basis of the current operational definitions of hypertension, but it is limited by the normal variability of blood pressure and the "white coat effect." By contrast, ambulatory blood pressure provides information on circadian variations in blood pressure and alterations due to changes in behavior, and may, therefore, be more appropriate for diagnosing hypertension. However, it is important to note that the values used to define normotension and hypertension for clinic blood pressure are not appropriate for ambulatory blood pressure. Recent population studies have proposed that the upper limit for 24-h ambulatory pressure should be 119 to 126/75 to 80 mm Hg, and failure to recognize this may account for at least some cases of "white-coat hypertension." There is increasing evidence that ambulatory blood pressure is more effective than clinic blood pressure in predicting the organ damage associated with hypertension, whereas data from intervention studies indicate that a reduction in ambulatory pressure is correlated with a reduction in left ventricular (LV) mass. Finally, ambulatory blood pressure measurements may provide a number of advantages in the development of antihypertensive therapies: by permitting better identification of trough and peak effects, by confirming that the efficacy of formulations for once-daily dosing is maintained throughout the 24-h period, and by minimizing the placebo effect.

    Ambulatory care-sensitive conditions (ACSC) are defined as conditions that lead to a hospital admission of which the onset could have been prevented through a more easily accessible ambulatory sector or one that provides better quality care. They are used by health-care systems as a quality indicator for the ambulatory sector. The definition for ACSC varies internationally. Sets of conditions have been defined and evaluated already in various countries, e. g., USA, England, New Zealand and Canada, but not yet for Germany. Therefore this study aims to evaluate the hospital costs of ACSC in Germany using the National Health Service's set of ACSC. In order to calculate these costs a model has been set up for the time period between 2003 and 2010. It is based on G-DRG browsers issued by the German Institute for the Hospital Remuneration System as required by German law. Within these browsers all relevant DRG-ICD combinations have been extracted. The number of cases per combination was then multiplied by their corresponding cost weights and the average effective base rates. The results were then aggregated into their corresponding ICD groups and then into their respective conditions which lead to the costs per condition and the total costs. The total number of cases and total costs were then compared to another second source. These calculations resulted in 11.7 million cases, of which 10.7% were defined as ambulatory care-sensitive. Within the analysed time period the number of ambulatory care-sensitive cases increased by 6% in total and had a 0.9% CAGR. The corresponding costs amounted to a total of EUR 37.6B and to EUR 3.3B for ACSC. 60% of the costs were caused by three of the 19 ACSC. These results validate that it is worthwhile to further investigate this quality indicator for the ambulatory sector. PMID:25918929

    The development of APD technologies enables physician to customize PD treatment for optimal dialysis. Dialysis dose can be increased with APD alone or in conjunction with daytime dwells. Although there is no strong evidence of the advantage over CAPD, APD is generally recommended for patients having a high peritoneal transport, outflow problems or high intraperitoneal pressure (IPP) and those who depend on caregivers for their dialysis. The benefits of APD over CAPD depends on the problems and treatment results among dialysis centers. Before starting the APD, medical, psychosocial and financial aspects, catheter function, residual renal function (RRF), body surface area and peritoneal transport characteristic must be evaluated. The recommended starting prescription for APD is the dwell volume of 1,500 ml/m2, 2 hours/cycle, and 5 cycles/session, which will provides 10-15 L of total volume and 10 hours per session. The IPP should be monitored and kept below 18 cmH2O. NIPD is accepted for patients with significant RRF. Anuric patients usually require 15-20 L of total fill volume and may need 1-2 day-dwells of 2L icodextrin or hypertonic glucose solutions. Small solute clearances and ultrafiltration depend on the peritoneal catheter function and dialysis schedule. The clinical outcomes and small solute clearances must be monitored and adjusted accordingly to meet the weekly total Kt/V urea > or = 1.7 and in low peritoneal transporters, the weekly total CCr should be > or = 45 L/1.73 m2. The volume status must be normal. To diagnose the peritonitis in NIPD patients, 1 L of PDF should be infused and permitted to dwell for 2 hours before sending for analysis. The differential of white cell count may be more useful than the total cell counts. In Siriraj Hospital, APD patients had 1.5-3 times less peritonitis than CAPD patients and most of our anuric patients can achieve the weekly total Kt/V urea target with 10 L of NIPD. PMID:22043586

    In France, ambulatory anaesthesia and surgery seem to be well codified. Many recommendations have been published by the Health Authority and the professional associations: they are summarized in this review. However, numerous practical problems persist: for example, two situations specific to paediatric practice are problematic parental comprehension and application of the information provided and poor access to strong analgesics outside the hospital. Despite this, the paediatric population is an ideal target for ambulatory care because of its usual good health and quicker recovery after minor injury as proven by the small percentage of failure and readmission.

    This article explores a handful of critical trends that have broad implications for ambulatory surgery centers and health care entities as a whole. As of the year 2000, the health care delivery system is experiencing broad changes and reconstruction in a variety of manners. One of the largest changes revolves around the accelerating movement of patient care from inpatient models to outpatient models, and the commensurate investment and development in outpatient systems and outpatient bricks and mortar. This metamorphosis is particularly evident as it relates to freestanding ambulatory surgery centers. This change in health care delivery will prove to have severe economic impacts on many of the nation's hospital systems. PMID:11140547

    Dialysis can be used in severe cases, but may not be well tolerated. In such patients, peritoneal drainage could be an alternative option for fluid removal. We report the case of a newborn with a truncus arteriosus who developed postoperatively a complicated clinical course with right ventricular dysfunction, prerenal condition as well as fluid overload despite diuretic therapy. Dialysis was indicated for fluid removal. Peritoneal dialysis was started using a surgically placed Tenckhoff catheter and stopped due to inefficacy and leaks and no other modalities of dialysis were used. However, the catheter was left in place over a period of two months for fluid drainage and removed because of unexplained fever. In order to determine the effect of peritoneal drainage, we selected a period of one week before and one week after the removal of the drain to compare daily clinical data, urine electrolytes and renal function and found a positive effect on fluid balance control. We conclude that the fluid removal by continuous peritoneal drainage is a simple and safe alternative that can be used to control fluid balance in infants after cardiac surgery. PMID:20379389

    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. PMID:27006828

    Introduction Spontaneous peritonitis, especially spontaneous fungal peritonitis (SFP), is an important and potentially fatal complication in patients with endstage liver disaese. We evaluated potential risk factors, microbiological findings, and outcome of patients with SFP compared to spontaneous bacterial peritonitis (SBP) in critically ill patients. Methods Retrospective analyses of critically ill patients with suspected spontaneous peritonitis. Results Out of 205 patients, 20 (10%) had SFP, 28 (14%) had SBP, 48 (24%) had peritonitis without microbiological findings (SP) and 109 (52%) had no-peritonitis (NP). APACHE II and SOFA score were significantly higher in patients with SFP (26; 22–28; p<0.004 and 16; 14–18; p<0.002), SBP (26; 22–28; p<0.004 and 16; 14–18; p<0.002) and SP (24; 18–30; p<0.045 and 14; 10–18; p<0.044) as compared to NP (22; 16–24 and 12; 10–14). CHILD Pugh classification was mainly CHILD C and MELD Score was in patients with SFP (34; 18–40; p<0.001), SBP (32;12–40 p<0.002) and SP (29; 14–40 p<0.003) significantly higher as compared to NP (25;8–40). Nosocomial peritonitis could be significantly more often found in patients with SFP (65%; p<0.023) and SBP (62%, p<0.030) as compared to SP (51 p = 0.243) and NP (45%). Antibiotic pretreatment last 3 month prior peritonitis was significantly more often in patients with SFP (85%; p<0.002), SBP (71%, p<0.033), and SP (56; p<0.040) as compared to NP (33%). Candida albicans (60%; 12/20) was the most common isolated fungus, followed by Candida glabrata (13%) and Candida krusei (13%). Mortality rate was significantly higher in patients with SFP (90%, p<0.001), followed by SBP (75%; p<0.001) and SP (69%; p<0.001) as compared to NP (45%). Conclusion SFP is not a rare complication in end stage liver disease which is associated with increased mortality. Physicians should be aware of SFP in patients with CHILD C liver cirrhosis, elevated MELD score, antibiotic pretreatment and

    Aims: We aimed to validate Mannheim peritonitis index (MPI) for prediction of outcome in patients with perforation peritonitis. Materials and Methods: A prospective study involving 100 subjects operated for perforation peritonitis over the period of 2 years was designed. Postevaluation of predesigned performa, MPI score was calculated and analyzed for each patient with death being the main outcome measure. The MPI scores were divided into three categories; scores <15 (category 1), 16-25 (category 2), and >25 (category 3). Results: Our study consisted of 82 males and 18 females (male:female ratio 4.56:1), with the mean patients age of 37.96 ± 17.49 years. 47, 26, and 27 cases belonged to MPI score categories 1, 2, and 3, respectively. The most common origin of sepsis was ileal with small intestine dominating the source of perforation. When the individual parameters of MPI score were assessed against the mortality only, age >50 years (P = 0.015), organ failure (P = 0.0001), noncolonic origin of sepsis (P = 0.002), and generalized peritonitis (P = 0.0001) significantly associated with mortality. The sensitivity of MPI was 92% with a specificity of 78% in receiver operating characteristic curves. Conclusion: MPI is an effective tool for prediction of mortality in cases of perforation peritonitis. PMID:26604619

    Interventional nephrologists and radiologists place peritoneal dialysis catheters using the percutaneous fluoroscopic technique in both the inpatient and outpatient setting. Nephrologists caring for such patients may have to diagnose and manage the complications resulting from these procedures. Abdominal pain can occur following peritoneal dialysis catheter placement when the local and systemic analgesia wears off. However, abdominal pain with hypotension is suggestive of a serious complication. Bleeding into the abdomen and perforation of the colon or bladder should be considered in the differential diagnosis. In the case reported here, the peritoneogram showed contrast in the bowel, and correct interpretation by the interventionist would have prevented this complication. The characteristic pattern of peritoneogram images in this case will guide interventionists to avoid this complication, and the discussion of the differential diagnosis and management will assist nephrologists in taking care of such patients.

    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

    Urgent-start peritoneal dialysis (PD) refers to the initiation of dialysis soon after a PD catheter placement and is a treatment option available to the late-referred patient with advanced kidney disease. This article reviews nursing aspects of urgent-start PD and can serve as a guide for this evolving clinical pathway that can provide renal replacement therapy for a critical segment of the population with Stage 5 chronic kidney disease who require renal replacement therapy.

    Peritoneal dialysis (PD) catheter-associated infections remain a challenging cause of technique failure. Patient training and preventive measures are key elements in the management of infection rates. Twenty-seven of the 167 PD catheter transfer sets analyzed (19%) yielded a positive microbial culture (58% gram-negative bacteria). These results show that subclinical contamination, particularly from environmental gram-negative bacteria, is a potential hazard, indicating the need for a protocol for regular transfer set changes.

    The Stoke Renal Unit has been at the forefront of peritoneal dialysis (PD) research for much of the past two decades. Central to this work is the PD cohort study, which was started in 1990 and is based on regular outpatient measurements of peritoneal and clinical function, correlating these with long-term outcomes. It has provided a wealth of information on risk factors for morbidity and mortality in patients on PD, the most significant being demonstration of the effects of time and dialysate glucose exposure on changes to the peritoneal membrane, as evidenced by increases in small solute transport. Early on, the study confirmed the adverse relationship between high small-solute transport status and outcome but more recently suggested that this relationship no longer held with modern techniques for managing patients on PD. Central themes of the PD research in Stoke have included evaluation of euvolemia, the importance of ultrafiltration and how best to achieve it, and detailed assessments of transmembrane water movement. The work has included the study of sodium removal and the use of novel low sodium dialysates. More recently, attention has turned to the significance of impaired ultrafiltration capacity in patients on PD as a sign of structural membrane damage. It is hoped that further work in this area will identify preventive strategies. PMID:21364207

    Although the treatment of gastric cancer improves the clinical outcomes, the survival of gastric cancer patients with peritoneal metastasis is still very poor. Effective drugs against peritoneal metastasis, coupled with new therapeutic modalities, are needed to improve the prognoses of these patients. Paclitaxel and TS-1 are candidate drugs for peritoneal metastasis, and intraperitoneal chemotherapy and targeted therapy are potential new therapeutic modalities. Two phase II studies using TS-1 and intraperitoneal and systemic paclitaxel for gastric cancer patients with peritoneal metastasis showed respectable survival results. In addition, peritoneal metastatic lesions showed high levels of epithelial cellular adhesion molecule (ECAM) and very low levels of human epidermal growth factor receptor 2 (HER2), thus indicating that an anti-ECAM monoclonal antibody, catumaxomab, would be effective against gastric cancer-derived peritoneal metastasis. Although catumaxomab and intraperitoneally administered paclitaxel are not generally used in Japan at present, these treatment strategies might therefore be effectively used in Japan in the near future.

    This pilot study describes the effect of intraoperative peritoneal lavage (IOPL) on bacterial counts and outcome in clinical cases of septic peritonitis. Intraoperative samples were cultured before and after IOPL. Thirty-three dogs with presumed septic peritonitis on the basis of cytology were managed surgically during the study period. Positive pre-lavage bacterial cultures were found in 14 cases, 13 of which were a result of intestinal leakage. The post-lavage cultures showed fewer isolates in 9 cases and in 1 case became negative. The number of dogs with a decrease in the concentration of bacteria cultured from pre-lavage to post-lavage samples was not statistically significant. There was no significant effect of the change in pre- to post-lavage culture, single versus multiple types of bacteria, selection of an appropriate empiric antimicrobial on survival or the need for subsequent surgery.

    1992-01-01

    Objective—To develop a complete system for the measurement, recording, and analysis of ambulatory pulmonary artery pressure. Design—The new system consists of a pulmonary artery catheter, an ambulatory recorder, and a desktop computer. Pulmonary artery pressure is measured by a micromanometer tipped catheter with an in vivo calibration system to allow correction for zero drift. This catheter is plugged into a small battery powered recorder. The recorder has two input channels, one for pressure and one for an event marker. The pressure wave is sampled 32 times/s, processed by an in built computer, compressed, and stored in semiconductor memory. On completion of a recording, data is transferred from the ambulatory recorder through a serial data link to an Acorn Archimedes desktop computer on which further data processing, statistical analysis, graphics, and printouts can be obtained. Results—The system has been used in 18 patients, with technically successful recording in 14, less than 15 minutes of data loss in three, and 12 hours of data loss in one. Conclusions—A new system for ambulatory pulmonary artery monitoring has been developed and used clinically with success. It may provide new perspectives on the pathophysiology of disease as it applies to everyday life. PMID:1389746

    Ambulatory blood pressure monitoring offers the ability to collect blood pressure readings several times an hour across a 24-hour period. Ambulatory blood pressure monitoring facilitates the identification of white-coat hypertension, the phenomenon whereby certain individuals who are not on antihypertensive medication show elevated blood pressure in a clinical setting but show non-elevated blood pressure averages when assessed by ambulatory blood pressure monitoring. Additionally, readings can be segmented into time windows of particular interest, e.g., mean daytime and nighttime values. During sleep, blood pressure typically decreases, or dips, such that mean sleep blood pressure is lower than mean awake blood pressure. A non-dipping pattern and nocturnal hypertension are strongly associated with increased cardiovascular morbidity and mortality. Approximately 70% of individuals dip ≥10% at night, while 30% have non-dipping patterns, when blood pressure remains similar to daytime average, or occasionally rises above daytime average. The various blood pressure categorizations afforded by ambulatory blood pressure monitoring are valuable for clinical management of high blood pressure since they increase accuracy for diagnosis and the prediction of cardiovascular risk.

    The ambulatory arterial stiffness index (AASI) and the symmetric ambulatory arterial stiffness index (s-AASI) have been shown to correlate to arterial stiffness in adults. This study assesses these indices with anthropometric and blood pressure (BP) measures in children. A total of 102 children at a pediatric hypertension clinic who had ambulatory blood pressure monitoring (ABPM) done from 2009 to 2013 were included (75% males, 7-22yo, 47% hypertensive, 24% prehypertensive, and 34% white-coat hypertensives). AASI is 1 minus the regression slope of diastolic BP values on systolic BP values from a 24-hour ambulatory blood pressure monitoring. s-AASI is the symmetric regression of AASI. Obese patients had a significantly higher AASI. s-AASI correlated with systolic BP variability. In multivariable regression, BP variability independently correlated with AASI and s-AASI. s-AASI is related to systolic dipping.AASI and s-AASI are highly dependent on BP variability in children. Further studies are necessary to assess their utility. PMID:27118486

    PubMed

    2012-01-01

    Adequate postoperative analgesia is a prerequisite for successful ambulatory surgery and remains a challenge. The problem of pain at home may be increasing because previously inpatient surgical procedures are becoming ambulatory and it is expected that the number and complexity of ambulatory surgical procedures will continue to increase. In 1998, we described the use of surgical-site and perineural catheter techniques that allowed patients to self-administer local anesthetics through disposable, elastomeric pumps for pain management at home. In recent years, availability of improved elastometric and other lightweight pump devices, the general trend of avoiding strong opioids and the preference for non-opioid analgesic techniques has led to increasing use of this technique after a variety of ambulatory surgical procedures. The two most common techniques are perineural and wound catheter infusions (WCI). Current evidence suggests that both are effective, although comparative studies are lacking. Perineural techniques are highly effective but are technically challenging and require labor-intensive and expensive home care that can be provided only in specialized centers. Disappointing past experience with implementation of perineural catheter techniques in inpatients suggests that it is unrealistic to expect their routine use in most ambulatory centers. Surgical-site catheter technique is a simpler, safer, and less expensive alternative and therefore more likely to gain widespread use. Only controlled comparisons can show whether the current belief about the superiority of ambulatory perineural techniques over WCI is justified. Such studies should address technical failures, side effects, home care of the medically unsupervised or undersupervised patient, and cost-effectiveness to demonstrate which of the 2 techniques is most appropriate for a particular procedure.

    Disseminated peritoneal leiomyomatosis (DPL) is a rare condition characterized by the presence of multiple histologically benign smooth muscle nodules on the surface subperitoneal tissue simulating macroscopic peritoneal carcinomatosis. This disease is rare, but in recent years, in connection with the widespread introduction of laparoscopic surgery, the reports of disseminated peritoneal leiomyomatosis occurring after laparoscopic morcellation, were frequent. The knowledge of DPL is necessary to develop methods of prevention, and individualized treatment depending on the pathogenesis and clinical manifestations in each patient. PMID:27509658

The differential diagnosis between advanced gastric cancer with peritoneal carcinomatosis and early gastric cancer with peritoneal tuberculosis (TB), and the treatment of these two diseases, were challenging in this case. Physicians should have a high index of suspicion for peritoneal TB if the patient has a history of this disease, especially in areas with a high incidence of TB, such as South Korea. An early diagnosis is critical for patient management and prognosis. A surgical approach including tissue biopsy or laparoscopic exploration is recommended to confirm the diagnosis. PMID:27433397

    A low-cost, ambulatory blood-pressure monitor has been calibrated and validated against a random zero sphygmomanometer. The repeatability of ambulatory pressure recordings after a placebo month in 44 mild to moderate untreated hypertensives was assessed. Systolic blood pressure showed a mean difference over 1 month of 2.0 mmHg, with a standard deviation of differences of 9.3 mmHg. The diastolic blood pressure mean difference was 0.1 mmHg (SD = 6.3 mmHg). This variability was much less than for clinic readings (SD = 17.3 mmHg) or for single home pressure readings (SD = 19.7 mmHg). Using ambulatory monitoring to detect a drop in pressure of 8/5 mmHg with a power of 0.9, the number of subjects needed in a parallel group trial is reduced from 360 to 68, and in a crossover study from 88 to 16 subjects. The usefulness of ambulatory pressure monitoring is demonstrated in a placebo-controlled comparison of atenolol, nifedipine retard, or their combination in random order. Eleven subjects, 21-60 years, with initial average blood pressures of 166.5/104.7 mmHg, showed a reduction in pressure with atenolol 50 mg a day of 15.1/10.0 mmHg, with nifedipine retard 20 mg b.i.d. of 21.0/11.6 mmHg, and with atenolol 50 mg and nifedipine retard 20 mg once a day of 26.2/16.8 mmHg. Ambulatory monitoring of pressure improved the accuracy of the trial and demonstrated a reduction in the alerting response with atenolol. PMID:2487802

    Chronic exposure to commercial glucose-based peritoneal dialysis fluids during peritoneal dialysis induces peritoneal membrane damage leading to ultrafiltration failure. In this study the role of protein kinase C (PKC) α in peritoneal membrane damage was investigated in a mouse model of peritoneal dialysis. We used 2 different approaches: blockade of biological activity of PKCα by intraperitoneal application of the conventional PKC inhibitor Go6976 in C57BL/6 wild-type mice and PKCα-deficient mice on a 129/Sv genetic background. Daily administration of peritoneal dialysis fluid for 5 weeks induced peritoneal upregulation and activation of PKCα accompanied by epithelial-to-mesenchymal transition of peritoneal mesothelial cells, peritoneal membrane fibrosis, neoangiogenesis, and macrophage and T cell infiltration, paralleled by reduced ultrafiltration capacity. All pathological changes were prevented by PKCα blockade or deficiency. Moreover, treatment with Go6976 and PKCα deficiency resulted in strong reduction of proinflammatory, profibrotic, and proangiogenic mediators. In cell culture experiments, both treatment with Go6976 and PKCα deficiency prevented peritoneal dialysis fluid-induced release of MCP-1 from mouse peritoneal mesothelial cells and ameliorated transforming growth factor-β1-induced epithelial-to-mesenchymal transition and peritoneal dialysis fluid-induced MCP-1 release in human peritoneal mesothelial cells. Thus, PKCα plays a crucial role in the pathophysiology of peritoneal membrane dysfunction induced by peritoneal dialysis fluids, and we suggest that its therapeutic inhibition might be a valuable treatment option for peritoneal dialysis patients.

    Gastro-oesophageal reflux has been assessed in 10 symptomatic patients and 10 asymptomatic normal subjects during a study period of 24 hours at work and in the home using a newly developed pH sensitive radiotelemetry capsule and a portable receiving system. Oesophageal pH was continuously monitored by the tethered radiotelemetry capsule and recorded with a portable receiver and a 24-hour cassette recorder, allowing the patient complete freedom of movement so that ambulatory studies could be undertaken during a normal working day. The number and duration of reflux episodes was greater in symptomatic patients than normal subjects during 24-hour studies at home (p less than 0.002). In both groups, reflux occurred more during the day than at night (p less than 0.01). Patients refluxed significantly more at home than when they were in hospital (p less than 0.01). Ambulatory outpatient oesophageal pH monitoring may be useful in the management of patients with atypical symptoms and may demonstrate significant reflux when inpatient investigations and endoscopy findings show minimal abnormality.

    Some employers are using reference-based benefit (RBB) designs, also known as "reference-based pricing," to encourage patients to select lower-price ambulatory surgery centers instead of expensive hospital outpatient departments. This article analyzes the impact of such benefit designs for cataract removal surgery from the period 2009-13, using data on 2,347 surgical patients covered by the California Public Employees Retirement System (CalPERS), in comparison to 14,867 patients enrolled in non-CalPERS Anthem Blue Cross plans, which are not covered by RBB. After adjusting for changes in patient case-mix and other factors, the shift to RBB was associated with an increase in ambulatory surgery center use by 8.6 percentage points compared to trends among Anthem enrollees. Total employer and employee payments per procedure, after adjusting for changes in case-mix severity and market factors, declined by 19.7 percent compared with Anthem enrollees not subject to RBB. Consumer cost-sharing requirements increased for CalPERS patients who continued to use hospital outpatient departments but who were not exempted from RBB because of geographic or clinical factors. Reference-based benefits for cataract surgery saved CalPERS $1.3 million in the two years after implementation. PMID:25732491

    Care of asthmatic children is often episodic and more therapeutic than preventive. A 2-year randomized, controlled trial involving 95 children measured the impact of a comprehensive home and ambulatory program for pediatric asthma management using objective outcome measures. Interventions for the study group during the first year included 3-month clinic visits, education, and home visits by a specially trained research nurse. Control subjects continued to receive regular care from a family physician or pediatrician. Eight-nine subjects (93%) completed the study. Study subjects had less school absenteeism than control subjects (10.7 vs. 16.0 days, P = .04) and showed significantly better small airway function after 1 year. Asthma severity improved in 13 study subjects and worsened in 5. The reverse was true for control subjects. Study subjects exhibited better metered aerosol technique than control subjects (P = .0005). Fewer days were spent in hospital by the study subjects admitted compared with control subjects (3.67 vs 11.2 days, P = .02). After 1 year, more study than control families (72.1% vs 33.1%, P = .006) reported that their asthmatic child took responsibility for the asthma management. The intervention failed to reduce exposure to secondhand smoke or to household pets. There were no significant differences in medical visits, theophylline levels, or records of asthma symptoms. One year after discontinuing the intervention, a marked "washout" effect was observed. Comprehensive ambulatory programs of childhood asthma management can improve objective measures of illness severity but must be sustained. PMID:1984619

    In Germany, the number and proportion of elderly people will continue to increase. Only few hospitals and rehabilitation units are currently providing inpatient geriatric services. Concepts for graded geriatric care see ambulatory geriatric rehabilitation (AGR) as an independent service und as a complement to pre-existing structures in geriatric care. In 2004, the national association of statutory health insurance funds established recommendations for AGR, which include criteria of structural and process quality of ambulant geriatric rehabilitation. This article describes various aspects of these framework recommendations (target groups, rehabilitation indicators, and equipment of services). In addition, the classification of AGR within the legislation of the statutory health insurance system is evaluated. The financing of AGR by the statutory health insurance system and the preconditions for accreditation of AGR-services within this system are discussed. The authors conclude that discrimination between existing partially-inpatient day clinics and AGR services is not appropriate. Furthermore, there is no legal basis for such a discrimination; on the contrary, the terms partially-inpatient and ambulatory rehabilitation services can be seen as a uniform benefit according to book 5 of the German social code, SGB V. Therefore there is no differentiation between AGR and partially-inpatient rehabilitation in the statutory health insurance system. PMID:16059839

    Accumulating evidence suggests that heart rate variability (HRV) alterations could serve as an indicator of sepsis progression and outcome, however, the relationships of HRV and major pathophysiological processes of sepsis remain unclear. Therefore, in this experimental study HRV was investigated in a clinically relevant long-term porcine model of severe sepsis/septic shock. HRV was analyzed by several methods and the parameters were correlated with pathophysiological processes of sepsis. In 16 anesthetized, mechanically ventilated, and instrumented domestic pigs of either gender, sepsis was induced by fecal peritonitis. Experimental subjects were screened up to the refractory shock development or death. ECG was continuously recorded throughout the experiment, afterwards RR intervals were detected and HRV parameters computed automatically using custom made measurement and analysis MATLAB routines. In all septic animals, progressive hyperdynamic septic shock developed. The statistical measures of HRV, geometrical measures of HRV and Poincaré plot analysis revealed a pronounced reduction of HRV that developed quickly upon the onset of sepsis and was maintained throughout the experiment. The frequency domain analysis demonstrated a decrease in the high frequency component and increase in the low frequency component together with an increase of the low/high frequency component ratio. The reduction of HRV parameters preceded sepsis-associated hemodynamic changes including heart rate increase or shock progression. In a clinically relevant porcine model of peritonitis-induced progressive septic shock, reduction of HRV parameters heralded sepsis development. HRV reduction was associated with a pronounced parasympathetic inhibition and a shift of sympathovagal balance. Early reduction of HRV may serve as a non-invasive and sensitive marker of systemic inflammatory syndrome, thereby widening the therapeutic window for early interventions. PMID:26779039

    Patients requiring cardiopulmonary bypass for congenital heart surgery commonly exhibit impaired renal function and extravascular fluid retention. These conditions contribute to early postoperative fluid overload, which may result in significant morbidity and mortality. We examined the safety and efficacy of peritoneal dialysis in removing extravascular fluid from critically ill postcardiotomy patients. A retrospective case review from July of 1995 through April of 1996 was conducted. All patients undergoing peritoneal dialysis achieved a net negative fluid balance. Average urine output increased from 2.1 cc/kg/hr to 3.9 cc/kg/hr (P < 0.01) during the pre-peritoneal dialysis to post-peritoneal dialysis period, and the mean number of inotropic agents decreased from 2.2 to 1.7 (P < 0.05). Controlled comparison revealed that the peritoneal dialysis cohort more rapidly achieved a negative weight-adjusted fluid balance throughout the early postoperative course. The peritoneal dialysis group's illness severity decreased more rapidly within the 24-hour period after initiation of peritoneal dialysis than did that of the control cohort over the same period of time. No difference in postoperative morbidity or mortality existed between the study groups. Complications from the catheter placement were minimal, and no patient experienced peritonitis or metabolic or hemodynamic instability during peritoneal dialysis catheter placement, usage, or removal. Peritoneal dialysis is a safe and effective form of renal replacement therapy, even among critically ill pediatric postcardiotomy patients. Early postsurgical institution of peritoneal dialysis may hasten early postoperative recovery. We speculate that intraoperative catheter placement reduces the complication rate associated with this treatment modality. PMID:9456479

    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

  1. Late presentation of encapsulating peritoneal sclerosis following renal transplantation and the potential under-reporting of the incidence and prevalence of encapsulating peritoneal sclerosis.

    2015-07-01

    Encapsulating peritoneal sclerosis is an infrequent but potentially devastating complication of peritoneal dialysis. The reported incidence and prevalence of encapsulating peritoneal sclerosis vary markedly between countries. Currently, peritoneal dialysis vintage remains the major risk factor for encapsulating peritoneal sclerosis, and dialysis vintage differs between countries due to the relative competing risks of transplantation, availability of haemodialysis and peritonitis. However, the diagnosis of encapsulating peritoneal sclerosis is often only established when patients have transferred modality to transplantation or haemodialysis. Switching treatment modality may potentially lead to an under-reporting of encapsulating peritoneal sclerosis, as many countries which collect data on dialysis patients in national registries often have separate registries for dialysis and transplant patients, and this may potentially lead to under-reporting of encapsulating peritoneal sclerosis in patients presenting after renal transplantation. Secondly, the question arises as to how long former peritoneal dialysis patients should be followed before a diagnosis of encapsulating peritoneal sclerosis can be confidently excluded. To highlight this point, we present four cases that developed symptomatic encapsulating peritoneal sclerosis more than 5 years, and in once case more than 10 years after the discontinuation of peritoneal dialysis. Delayed or late presentation may not only delay the diagnosis, but also risk surgical interventions by non-specialists. A more robust system is required to record cases of encapsulating peritoneal sclerosis to determine the incidence and prevalence, and so provide accurate information to both patients and clinicians as to the risks of long-term peritoneal dialysis therapy.

    The world is becoming more and more health conscious. Society, health policy and patients' needs are all changing dramatically. The challenges society is currently facing are related to the increase in the aging population, changes in lifestyle, the need for healthcare cost containment and the need for improvement and monitoring of healthcare quality. The emphasis is put on prevention rather than on treatment. In addition, patients and health consumers are waiting for non-invasive or minimally-invasive diagnosis and treatment methods, for home care, short stays in hospital, enhancement of rehabilitation, information and involvement in their own treatment. Progress in science and technology offers, today, miniaturization, speed, intelligence, sophistication and new materials at lower cost. In this new landscape, microtechnologies, information technologies and telecommunications are key factors. Telemedicine has also evolved. Used initially to exchange patients' files, radiographic data and other information between health providers, today telemedicine contributes to new trends in "hospital extension" through all-day monitoring of vital signs, professional activities, entertainment and home-based activities. The new possibilities for home care and ambulatory monitoring are provided at 4 levels: a) Microsensors. Microtechnologies offer the possibility of small size, but also of intelligent, active devices, working with low energy, wireless and non-invasive or minimally-invasive; b) Wrist devices are particularly user friendly and combine sensors, circuits, supply, display and wireless transmission in a single box, very convenient for common physical activities; c) Health smart clothes make contact with 90 % of the skin and offer many possibilities for the location of sensors. These sensors have to be thin, flexible and compatible with textiles, or made using textile technologies, such as new fibers with specific (mechanical, electrical and optical) properties; d

    Objective Patients with suspected mesial temporal lobe (MTL) epilepsy typically undergo inpatient video–electroencephalography (EEG) monitoring with scalp and/or intracranial electrodes for 1 to 2 weeks to localize and lateralize the seizure focus or foci. Chronic ambulatory electrocorticography (ECoG) in patients with MTL epilepsy may provide additional information about seizure lateralization. This analysis describes data obtained from chronic ambulatory ECoG in patients with suspected bilateral MTL epilepsy in order to assess the time required to determine the seizure lateralization and whether this information could influence treatment decisions. Methods Ambulatory ECoG was reviewed in patients with suspected bilateral MTL epilepsy who were among a larger cohort with intractable epilepsy participating in a randomized controlled trial of responsive neurostimulation. Subjects were implanted with bilateral MTL leads and a cranially implanted neurostimulator programmed to detect abnormal interictal and ictal ECoG activity. ECoG data stored by the neurostimulator were reviewed to determine the lateralization of electrographic seizures and the interval of time until independent bilateral MTL electrographic seizures were recorded. Results Eighty-two subjects were implanted with bilateral MTL leads and followed for 4.7 years on average (median 4.9 years). Independent bilateral MTL electrographic seizures were recorded in 84%. The average time to record bilateral electrographic seizures in the ambulatory setting was 41.6 days (median 13 days, range 0–376 days). Sixteen percent had only unilateral electrographic seizures after an average of 4.6 years of recording. Significance About one third of the subjects implanted with bilateral MTL electrodes required >1 month of chronic ambulatory ECoG before the first contralateral MTL electrographic seizure was recorded. Some patients with suspected bilateral MTL seizures had only unilateral electrographic seizures

    Phagocytosis, intracellular killing of Candida albicans, and superoxide production by rat peritoneal macrophages exposed to aflatoxins B1, B2, G1, G2, B2a, and M1 at several times and concentrations were analyzed to evaluate the intensity of a depressive effect for each mycotoxin. All aflatoxins used at very low concentrations had a depressive effect on the functions of macrophages. The biggest impairment of phagocytosis, intracellular killing, and spontaneous superoxide production was observed in macrophages exposed to aflatoxins B1 and M1. PMID:2176448

    A 34-year-old female presented with end-stage renal disease (ESRD) treated by peritoneal dialysis (CAPD) complained of a dry cough. Chest X-ray and chest computed tomography (CT) scan revealed massive right hydrothorax. Because the glucose concentration of pleural fluid was markedly high compared with that of serum, we performed isotope and contrast peritoneography. We used CT for localizing it. MRI was also trying to show transdiaphragmatic leakage in peritoneoflural fistula. Temporary discontinuation of CAPD, tetracycline instillation into the pleural space and surgical patch grafting of the diaphragmatic leak have all been described. A novel method may be video-assisted talc pleurodesis. PMID:22111056

    To detect vascular variability anomalies (VVAs), a blood pressure and heart rate profile around the clock for at least 7 days is a start. As a minimum, measurement every 60 or preferably 30 minutes for a week is needed, to be continued if abnormality is found, to assess the about 24-hour (circadian) variability that exists in all individuals. As a first dividend, one then also obtains a glimpse of 2 of the very many longer-than-circadian periodicities, the biological half-week and week.

    2015-08-01

    Although the number of new drug shortages has been lower in recent years than in the past, severe shortages have occurred that have affected large numbers of patients. A new law entitled the Food and Drug Administration Safety and Innovation Act was enacted in July of 2012, which requires companies to notify the Food and Drug Administration of anticipated shortages. This notification requirement has allowed the Food and Drug Administration to work closely with manufacturers earlier to mitigate and, often, prevent shortages. However, not all shortages are able to be prevented, and the shortage of peritoneal dialysis solution is one that has had a significant effect on patients. The Food and Drug Administration continues to use all available tools to address this shortage with manufacturers, including temporary availability of imported peritoneal dialysis solution from Ireland. Mitigating shortages is a top priority for the Food and Drug Administration, and communication with all stakeholders is essential. PMID:25896999

    The implementation of shared governance structures in acute care has illustrated the positive relationship between shared decision making and nurse empowerment and positive nurse and patient outcomes. Little is known, however, about interdisciplinary shared governance, and even less is known about shared governance in ambulatory care. This article details one health system's experience with the implementation of an interdisciplinary shared governance structure in ambulatory care over a 4-year period. The authors report lessons learned, positive health system outcomes that resulted including improved communication, better preparedness for accreditation visits, improved assessment of fall risk, and a streamlined documentation system. Also discussed are mechanisms to enhance sustainability of the structure and discussion of future opportunities and challenges. PMID:27259130

  13. Ambulatory assessment in panic disorder and specific phobia.

    PubMed

    2009-12-01

    Anxiety disorders are among the most prevalent mental disorders. In panic disorder, panic attacks often occur at unpredictable times, making it difficult to study these episodes in the laboratory. In specific phobias, symptoms occur in very circumscribed situations and specific triggers are sometimes difficult to reproduce in the laboratory. Ambulatory assessment, or ecological momentary assessment, can further the understanding of the natural course and scope of symptoms under ecologically valid circumstances. Because bodily symptoms are integral to the diagnosis of anxiety disorders, the objective assessment of physiological responses in the patients' natural environment is particularly important. On the one hand, research has highlighted intriguing discrepancies between the experience of symptoms and physiology during panic attacks. On the other hand, it has validated symptom reporting during therapeutic exposure to phobic situations. Therefore, ambulatory assessment can yield useful information about the psychopathology of anxiety disorders, and it can be used to monitor change during clinical interventions. PMID:19947782

    Mesothelial-to-mesenchymal transition (MMT) is an autoregulated physiological process of tissue repair that in uncontrolled conditions, such as peritoneal dialysis (PD), can lead to peritoneal fibrosis. The maximum expression of sclerotic peritoneal syndromes (SPS) is the encapsulating peritoneal sclerosis (EPS) for which no specific treatment exists. The SPS includes a wide range of peritoneal fibrosis that appears progressively and is considered as a reversible process, while EPS does not. EPS is a serious complication of PD characterized by a progressive intra-abdominal inflammatory process that results in bridles and severe fibrous tissue formation which cover and constrict the viscera. Recent studies show that transdifferentiated mesothelial cells isolated from the PD effluent correlate very well with the clinical events such as the number of hemoperitoneum and peritonitis, as well as with PD function (lower ultrafiltration and high Cr-MTC). In addition, in peritoneal biopsies from PD patients, the MMT correlates very well with anatomical changes (fibrosis and angiogenesis). However, the pathway to reach EPS from SPS has not been fully and completely established. Herein, we present important evidence pointing to the MMT that is present in the initial peritoneal fibrosis stages and it is perpetual over time, with at least theoretical possibility that MMT initiated the fibrosing process to reach EPS.

    Purpose The purpose of this study was to explore nurses’ perceptions of nurse-physician relationships in ambulatory oncology settings, which are linked to patient safety. Design This cross-sectional, descriptive study analyzed survey data collected in 2010 from oncology nurses employed in ambulatory settings. The sampling frame was the nurse licensure database in one state in the Southeastern United States. Nurses completed the Practice Environment Scale of the Nursing Work Index (PES-NWI), reported on the quality of care in their setting, and commented on factors that promoted or inhibited high-quality care delivery. Methods Data analysis used three study variables: empirically-derived values from the PES-NWI, a scale of nurse-reported quality of care in their setting, and open-text comments about features in their workplace that promoted or hindered high-quality care. After categorizing open-text comments, ANOVA was used to evaluate differences in PES-NWI subscales by comment category. Chi-square test statistics were calculated to examine differences in overall practice environment and quality of care by comment category. Results Nurses reported their relationships with physicians as generally favorable. Qualitative findings suggest two themes that influence how nurses characterize their working relationships with physicians: 1) physician behaviors and 2) structural factors. Both PES-NWI scores and quality of care were rated significantly higher by nurses who wrote favorably about physicians. Conclusions Favorable nurse-physician relationships in ambulatory settings may reflect positive workplaces and promote high-quality care. Clinical Relevance Consistent with findings from inpatient units, nurse-physician relationships are important to the quality of ambulatory oncology care. Systematic measurement and attention to reported deficits in these relationships may promote higher quality care. PMID:22812518

    Capacity management seeks to improve organizational effectiveness by increasing operational efficiency and reducing patient congestion. A framework for capacity management, including demand-smoothing and supply-matching strategies, provides structure for a manager's approach to effective ambulatory care.

Rather than increase the clinical resource base, a balanced set of relevant, low-cost strategies was proposed to improve performance. PMID:10302492

    OBJECTIVE To analyze the temporal evolution of the hospitalization of older adults due to ambulatory care sensitive conditions according to their structure, magnitude and causes. METHODS Cross-sectional study based on data from the Hospital Information System of the Brazilian Unified Health System and from the Primary Care Information System, referring to people aged 60 to 74 years living in the state of Rio de Janeiro, Souhteastern Brazil. The proportion and rate of hospitalizations due to ambulatory care sensitive conditions were calculated, both the global rate and, according to diagnoses, the most prevalent ones. The coverage of the Family Health Strategy and the number of medical consultations attended by older adults in primary care were estimated. To analyze the indicators’ impact on hospitalizations, a linear correlation test was used. RESULTS We found an intense reduction in hospitalizations due to ambulatory care sensitive conditions for all causes and age groups. Heart failure, cerebrovascular diseases and chronic obstructive pulmonary diseases concentrated 50.0% of the hospitalizations. Adults older than 69 years had a higher risk of hospitalization due to one of these causes. We observed a higher risk of hospitalization among men. A negative correlation was found between the hospitalizations and the indicators of access to primary care. CONCLUSIONS Primary healthcare in the state of Rio de Janeiro has been significantly impacting the hospital morbidity of the older population. Studies of hospitalizations due to ambulatory care sensitive conditions can aid the identification of the main causes that are sensitive to the intervention of the health services, in order to indicate which actions are more effective to reduce hospitalizations and to increase the population’s quality of life.

    We report a rare case of idiopathic sclerosing encapsulating peritonitis (SEP). During a laparotomy before undergoing a distal gastrectomy with Billroth II reconstruction for early gastric cancer, the patient was found to have a membranous encapsulation wrapping each small bowel loop, unlike peritoneal encapsulation or typical SEP. He had complained of persistent heartburn, distension and diarrhea for 2 months in the post-operative course. The second laparotomy, which was performed to improve prolonged transit, revealed typical SEP with a thick and fibrotic membrane that encased the small bowel entirely. Stripping of the sclerosing encasing membrane, separation of the adherent loops of the proximal small bowel, and Braun's anastomosis were performed. The patient complained of epigastric fullness and diarrhea after he was relieved from the complete bowel obstruction for 45 days post-operatively. Trimebutine maleate was administrated 5 months after the second operation and this markedly improved his symptoms. This case might reflect the developmental process of idiopathic SEP. In addition, the use of a motility regulator may improve symptoms related to the abnormal intestinal motility by this disease. PMID:10228820

    BACKGROUND: Cancer is the second leading cause of death in the United States and a major contributor to healthcare expenditure. There are few studies examining disparities in treatment costs. Studies that do exist are dominated by the cost of hospital care. METHODS: Utilizing Maryland Medicaid administrative claims data, a retrospective cohort, design was employed to examine disparities in ambulatory treatment costs of breast, colorectal and prostate cancer treatment by region, race and gender. We report mean and median results by each demographic category and test for the statistical significance of each. Lorenz curves are plotted and Gini coefficients calculated for each type of cancer. RESULTS: We do not find a consistent trend in ambulatory costs across the three cancers by traditional demographic variables. Lorenz curves indicate highly unequal distributions of costs. Gini coefficients are 0.687 for breast cancer, 0.757 for colorectal cancer and 0.774 for prostate cancer. CONCLUSION: Significant variation in nonhospital-based expenditures exists for breast, colorectal and prostate cancers in a population of homogeneous socioeconomic status and uniform insurance entitlement. Observed individual-level disparities are not consistent across cancers by region, race or gender, but the majority of this low-income population receives very little ambulatory care.

    People with multiple sclerosis (MS) experience a high rate of falls and have decreased static and dynamic balance. The purpose of this study was to determine best predictors of static standing balance, as measured by a single limb stance (SLS) timed test, in ambulatory persons with MS (PwMS) from among commonly used medical and rehabilitation clinical tests. Ambulatory PwMS participated in a single test session. Medical exam data gathered included the Function System (FS) neurologic exam and Expanded Disability Status Score (EDSS). A variety of commonly administered rehabilitation clinical tests addressing static balance, dynamic balance, gait endurance, functional lower extremity strength, abdominal and respiratory muscle strength were completed. Descriptive statistics, Pearson product moment correlations, and forward step-wise linear regressions were calculated. Twenty-eight ambulatory PwMS completed this study. Mean age was 54.74 years. Mean SLS score was 14.6 s. Pyramidal, sensory, bowel/bladder, and visual FS scores and the EDSS were significantly correlated with SLS. Maximal step length scores were significantly correlated with SLS at P less than 0.05 and the Functional Stair Test (FST) and 6-min walk test were correlated with SLS at P less than 0.10. Medical exam data EDSS and FS sensory explain 72.1% of the variance in SLS scores. Rehabilitation exam data FS sensory and FST explain 68.8% of the variance. The FS sensory, EDSS, and FST together explain 73.3% of the variance. PMID:26579696

    Spirometry performed in the ambulatory setting is an invaluable tool for diagnosis, monitoring, and evaluation of respiratory health in patients with chronic lung disease. If spirometry is not performed according to American Thoracic Society (ATS) guidelines, unnecessary repeated testing, increased expenditure of time and money, and increased patient and family anxiety may result. Two respiratory therapists at Mission Health System in Asheville, NC, identified an increase in patients arriving at the pulmonary function testing (PFT) laboratories with abnormal spirometry results obtained in the ambulatory setting. These abnormal results were due to incorrect testing procedure, not chronic lung disease. Three training methods were developed to increase knowledge of correct spirometry testing procedure in the ambulatory setting. The therapists also created a plan to educate offices that do not perform spirometry on the importance and availability of PFT services at our hospital for the population of patients with chronic lung disease. Notable improvements in posttraining test results were demonstrated. The education process was evaluated by a leading respiratory expert, with improvements suggested and implemented. Next steps are listed. PMID:26828578

    2014-09-01

    With the progress of technologies of recent years, methods have become available that use wearable sensors and ambulatory systems to measure aspects of--particular axial--motor function. As Parkinson's disease (PD) can be considered a model disorder for motor impairment, a significant number of studies have already been performed with these patients using such techniques. In general, motion sensors such as accelerometers and gyroscopes are used, in combination with lightweight electronics that do not interfere with normal human motion. A fundamental advantage in comparison with usual clinical assessment is that these sensors allow a more quantitative, objective, and reliable evaluation of symptoms; they have also significant advantages compared to in-lab technologies (e.g., optoelectronic motion capture) as they allow long-term monitoring under real-life conditions. In addition, based on recent findings particularly from studies using functional imaging, we learned that non-motor symptoms, specifically cognitive aspects, may be at least indirectly assessable. It is hypothesized that ambulatory quantitative assessment strategies will allow users, clinicians, and scientists in the future to gain more quantitative, unobtrusive, and everyday relevant data out of their clinical evaluation and can also be designed as pervasive (everywhere) and intensive (anytime) tools for ambulatory assessment and even rehabilitation of motor and (partly) non-motor symptoms in PD.

    Systemic arterial hypertension is the prevalentest disease worldwide that significantly increases cardiovascular risk. An early diagnosis together to achieve goals decreases the risk of complications significatly. Recently have been updated the diagnostic criteria for hypertension and the introduction of ambulatory blood pressure monitoring. The introduction into clinical practice of ambulatory blood pressure monitoring was to assist the diagnosis of «white coat hypertension» and «masked hypertension». Today has also shown that ambulatory blood pressure monitoring is better than the traditional method of recording blood pressure in the office, to the diagnosis and to adequate control and adjustment of drug treatment. Also there have been introduced important new concepts such as isloted nocturnal hypertension, morning blood pressure elevation altered and altered patterns of nocturnal dip in blood pressure; which have been associated with increased cardiovascular risk. Several studies have shown significant prognostic value in some stocks. There are still other concepts on which further study is needed to properly establish their introduction to clinical practice as hypertensive load variability, pulse pressure and arterial stiffness. In addition to setting values according to further clinical studies in populations such as elderly and children. PMID:26794338

    The development of composite measures of ambulatory care quality is an area of growing practice and policy interest. Using 29 semistructured interviews, this study describes the opinions of stakeholders related to the use and development of composite measures in a multistakeholder setting. Research experts working in multistakeholder settings need to understand the perspective of various stakeholders, many of whom have varying levels of research expertise, in order to develop useful and acceptable composite measures. Findings from this study suggest that to achieve maximal stakeholder buy-in, research experts should focus on clinical area-specific composites that are designed and constructed in a simple and transparent manner. However, composite measures are not a panacea for improving the utility of public reporting. Performance measure and report card creators should continue to investigate other ways to improve the user-friendliness of their reports and to address other barriers that prevent more extensive use of reports.

    Psychophysiological monitoring can be used to assess emotional reactivity in cardiovascular measures. Since blood pressure (BP) variability in daily life is primarily caused by physical activity, metabolic and nonmetabolic effects are confounded. A newly developed method of multiple accelerometry allows for the control of such unwanted variances by continuously detecting posture, general activity, and distinct movement patterns. Contingent on episodes of additional heart rate (AHR), an indicator of emotional reactivity, BP measurements can be triggered and participants prompted to enter their current mood in a handheld PC. To evaluate both new methods for BP research, we performed 24-h ambulatory monitoring with 40 normotensive student participants, an evaluation designed to include standard settings for a controlled comparison (library vs. cinema). Findings indicated that the group at the cinema showed higher values of AHR, but group differences in BP were not observed. On the whole, such multiple accelerometry and interactive monitoring appear to be useful methods in behavior research. PMID:17958150

    Purpose To examine the effect of body weight supported treadmill training (BWSTT) on gait and gross motor skill development in children (2–5 years old) with developmental delay who are ambulatory. Methods Twenty-four subjects (12 control, 12 BWSTT) were enrolled in this randomized control trial. All subjects continued to receive physical therapy. Subjects were tested at baseline, 4 weeks, 6 weeks, and at 6 weeks following completion of BWSTT. Outcomes were assessed using the 10 Meter Walk Test (10MWT) and Gross Motor Function Measure- D and E. Results Significant improvements were seen in gait velocity and gross motor skill attainment. With positive interactions in both the 10MWT and GMFM-E, the BWSTT group as compared to the control group demonstrated functional gains in gait velocity and gross motor skills, P = .033 and.017, respectively. Conclusions A 6-week high intensity BWSTT program can improve gait velocity and influence functional gains. PMID:26397083

    Each stage of a product's life cycle requires marketing strategy modifications in response to changing demand levels. The purpose of this study was to investigate changes in ambulatory care center (ACC) operational characteristics indicative of product, market, and distribution channel adjustments that could have a competitive impact upon community pharmacy practice. A questionnaire was mailed to a national sample of 325 ACC managers. Evidence of new product feature additions includes increased emphasis on continued care and increased prevalence of prescription drug dispensing. Expansion into new market segments and distribution channels was demonstrated by increased participation in HMO and employer relationships. The observed adjustments in ACC marketing strategies present obvious challenges as well as less obvious opportunities for community pharmacy practice. PMID:10295634

    There are multiple demands and challenges inherent in establishing staffing models in ambulatory heath care settings today. If health care administrators establish a supportive physical and interpersonal health care environment, and develop high-performing interprofessional teams and staffing models and electronic documentation systems that track performance, patients will have more opportunities to receive safe, high-quality evidence-based care that encourages patient participation in decision making, as well as provision of their care. The health care organization must be aligned and responsive to the community within which it resides, fully invested in population health management, and continuously scanning the environment for competitive, regulatory, and external environmental risks. All of these challenges require highly competent providers willing to change attitudes and culture such as movement toward collaborative practice among the interprofessional team including the patient.

    Orthostatic intolerance (OI) continues to be a problem experienced by astronauts upon return from spaceflight. Artificial gravity (AG) training via short radius centrifugation has been suggested as a countermeasure to this OI. The purpose of our research was to determine effects of three weeks of intermittent (+1 to +2.5 Gz for 35 min/day) AG exposure on normal, ambulatory men and women. The results of this study indicate that 3 weeks of AG training improved orthostatic tolerance in a group of 14 men and 12 women by an average of 13.6%. This improvement was associated with a decrease in arterial pressure and vascular resistance, and increases in stroke volume and low frequency (0.04-0.15 Hz) arterial pressure and heart rate spectral power. These results suggest that improvement may be attributable to increased venous return possibly as a function of increased stress-induced sympathetic activity and/or vascular sympathetic responsiveness.

    Clinical ladders, or career advancement systems, were designed to enhance professional development, provide a reward system for quality clinical performance, promote quality nursing practice, and improve job satisfaction among nurses. Most of the literature on RN clinical ladder programs is related to the acute care setting, where these programs originated; not much is known about their effectiveness in the ambulatory care environment. The RN Career Ladder at Kaiser Permanente of Colorado was begun by a Labor Management Partnership Committee in 2003, and awards financial incentives to RNs who demonstrate a commitment to continuing education, leadership activities, and program development on a local and regional level. In this study significantly more involvement in leadership, interdisciplinary, and quality improvement activities were found among career ladder nurses than non-career ladder nurses, regardless of their job role. It is not clear whether nursing leaders gravitate toward a career ladder or whether career ladder participation encourages increased participation in leadership activities. PMID:19330969

    This thesis is based on clinical studies including virtually all patients treated with peritoneal dialysis in Gothenburg during the 1990s. The patients had a fundamentally altered body composition compared to healthy subjects, characterised by a reduction in body cell mass and body fat already at start of dialysis. During PD treatment. a further decrease in body cell mass was observed. Energy stores tended to normalise during the first years of treatment and remained constant thereafter, or declined subsequently. Extracellular water, calculated from the four-compartment model, was increased when patients started PD treatment and increased further, in parallel to the reduction in body cell mass. These alterations were seen in combination with a normal. or slightly reduced, body weight. Standard methods of assessing nutritional status may therefore not be valid in the dialysis population. Prediction equations to estimate total body water, used in measurements of dialysis adequacy, give erroneous results in PD patients, as shown in a study on our PD population. This may have important clinical consequences, especially in wasted patients. Reduced muscle mass is a marker of protein-energy malnutrition, and therefore simple and reliable methods to measure muscle mass are warranted. When lean body mass was calculated from creatinine generation rate and compared to lean body mass estimated from measurements of total body potassium. the agreement between the two methods was low. Furthermore, when repeated measurements of creatinine generation rate were performed, the variation coefficient was unacceptably high. Thus. creatinine generation rate cannot be recommended as a method to evaluate somatic protein status in PD patients. The lipoprotein metabolic derangements are pronounced in PD patients. in which a further increase in cholesterol and cholesterol-rich apoB-containing lipoproteins are added to the already pre-existing renal dyslipidemia. characterised by increased

    Background There is currently a paucity of devices available for continuous, long-term monitoring of human joint motion. Non-invasive, inexpensive devices capable of recording human activity and joint motion have many applications for medical research. Such a device could be used to quantify range of motion outside the gait laboratory. The purpose of this study was to test the accuracy of the modified Intelligent Device for Energy Expenditure and Activity (IDEEA) in measuring knee flexion angles, to detect different physical activities, and to quantify how often healthy subjects use deep knee flexion in the ambulatory setting. Methods We compared Biomotion Laboratory (BML) "gold standard" data to simultaneous IDEEA measures of knee motion and gait, step up/down, and stair descent in 5 healthy subjects. In addition, we used a series of choreographed physical activities outside the BML to confirm the IDEEA's ability to accurately measure 7 commonly-performed physical activities. Subjects then continued data collection during ordinary activities outside the gait laboratory. Results Pooled correlations between the BML and IDEEA knee flexion angles were .97 +/- .03 for step up/down, .98 +/- .02 for stair descent, and .98 +/- .01 for gait. In the BML protocol, the IDEEA accurately identified gait, but was less accurate in identifying step up/down and stair descent. During sampling outside the BML, the IDEEA accurately detected walking, running, stair ascent, stair descent, standing, lying, and sitting. On average, subjects flexed their knees >120° for 0.17% of their data collection periods outside the BML. Conclusion The modified IDEEA system is a useful clinical tool for evaluating knee motion and multiple physical activities in the ambulatory setting. These five healthy subjects rarely flexed their knees >120°. PMID:16970818

    Implantable loop recorders (ILRs) continuously monitor electrocardiographic signals and perform real-time analysis of heart rhythm for up to 36 months. ILRs are used to evaluate transitory loss of consciousness from possible arrhythmic origin, particularly unexplained syncope, and to evaluate difficult cases of epilepsy and unexplained falls, although current indications for their application in these areas are less clearly defined. This article analyzes the current indications for ILRs according the European Society of Cardiology guidelines on the management of syncope and the European Heart Rhythm Association guidelines on the use of implantable and external electrocardiogram loop recorders, and their limitations.

    Peritoneal dissemination represents a devastating form of gastric cancer (GC) progression with a dismal prognosis. There is no effective therapy for this condition. The 5-year survival rate of patients with peritoneal dissemination is 2%, even including patients with only microscopic free cancer cells without macroscopic peritoneal nodules. The mechanism of peritoneal dissemination of GC involves several steps: detachment of cancer cells from the primary tumor, survival in the free abdominal cavity, attachment to the distant peritoneum, invasion into the subperitoneal space and proliferation with angiogenesis. These steps are not mutually exclusive, and combinations of different molecular mechanisms can occur in each process of peritoneal dissemination. A comprehensive understanding of the molecular events involved in peritoneal dissemination is important and should be systematically pursued. It is crucial to identify novel strategies for the prevention of this condition and for identification of markers of prognosis and the development of molecular-targeted therapies. In this review, we provide an overview of recently published articles addressing the molecular mechanisms of peritoneal dissemination of GC to provide an update on what is currently known in this field and to propose novel promising candidates for use in diagnosis and as therapeutic targets.

    Patient: Male, 65 Final Diagnosis: Peritoneal amyloidosis Symptoms: Anasarca • Dyspnea • Orthopnea Medication: — Clinical Procedure: Paracentesis and peritoneal biopsy Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course 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

    Recent studies have reported increases of methylglyoxal (MGO) in peritoneal dialysis patients, and that MGO-mediated inflammation plays an important role in the development of peritoneal fibrosis through production of transforming growth factor-β1 (TGF-β1). Linagliptin, a dipeptidyl peptidase-4 inhibitor, exerts anti-inflammatory effects independent of blood glucose levels. In this study, we examined whether linagliptin suppresses MGO-induced peritoneal fibrosis in mice. Male C57/BL6 mice were divided into three groups: control, MGO injection plus saline, and MGO injection plus linagliptin (n = 6 per group). Peritoneal fibrosis was induced by daily intraperitoneal injection of saline containing 40 mmol/L MGO for 21 days. Saline was administered intraperitoneally to the control group. Linagliptin (10 mg/kg) or saline were administrated by once-daily oral gavage from 3 weeks before starting MGO injections. Immunohistochemical staining revealed that linagliptin suppressed expression of α-smooth muscle actin and fibroblast-specific protein-1, deposition of type I and III collagen, and macrophage (F4/80) infiltration. Peritoneal equilibration testing showed improved peritoneal functions in mice treated with linagliptin. Peritoneal injection of MGO increased plasma levels of glucagon-like peptide-1 (GLP-1) in mice, and a further increase was observed in linagliptin-treated mice. Although MGO increased plasma glucose levels, linagliptin did not decrease plasma glucose levels. Moreover, linagliptin reduced the TGF-β1 concentration in the peritoneal fluid of MGO-treated mice. GLP-1 receptor (GLP-1R) was expressed in monocytes/macrophages and linagliptin suppressed GLP-1R expression in MGO-injected mice. These results suggest that oral administration of linagliptin ameliorates MGO-induced peritoneal fibrosis. PMID:27513960

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

    This paper describes the work of a military physician in an army healthcare institution and the scope and aim of activity of medical corps. The analysis includes data collected over one year and shows that officers and non-commissioned officers are more frequent users of medical services than conscripts. The consumption of medical products is high in both populations. The military physician has to face a number of organisational difficulties in everyday practice which diminish the quality of health services. Resolving these difficulties is a priority, especially in view of high healthcare and organisational standards set by NATO, which are eventually to be adopted and maintained by the Croatian medical corps in the process of joining. One of the tasks with that aim is to provide a continued medical training for military healthcare personnel. PMID:14994648

    Encephalopathy is a rare side effect of third and fourth generation cephalosporins. Renal failure and preexisting neurological disease are notable risk factors. Recognition is important as discontinuing the offending agent usually resolves symptoms. We present a case of acute encephalopathy in a patient with end stage renal disease (ESRD) treated with peritoneal dialysis (PD) who received intravenous ceftriaxone for peritonitis. This case illustrates the potential severe neurologic effects of cephalosporins, which are recommended by international guidelines as first-line antimicrobial therapy for spontaneous bacterial peritonitis.

    Many inflammatory and infectious entities may acutely affect the peritoneum causing a thickening of its layers. Unfortunately, several acute peritoneal diseases can have overlapping features, both clinically and at imaging. Therefore, the awareness of the clinical context, although useful, may be sometimes insufficient to identify the underlying cause. This article provides a specific computed tomography-based approach including morphologic characteristics of peritoneal thickening (e.g., smooth, irregular, or nodular) and ancillary findings to narrow the differential diagnosis of acute peritonitis.

    Hydrothorax in a patient treated with peritoneal dialysis (PD) poses a diagnostic dilemma. Hydrothorax due to migration of dialysis fluid across the diaphragm and into the pleural space creates a serious complication of PD but generally does not threaten life. Shortness of breath causes the patient to seek medical attention. A sudden diminution in dialysis adequacy or poor ultrafiltration rate constitutes a unique marker for patients treated with PD compared to the general population. This article reviews the etiology for hydrothorax specifically in the PD population. Thoracentesis with chemical analysis of the fluid, imaging studies with and without contrast or markers, and video-assisted thoracoscopic surgery play important roles in the evaluation of hydrothorax. A conservative PD regimen, surgical intervention, and pleurodesis provide treatment options to those receiving PD. PMID:20056973

    Malignant peritoneal mesothelioma (MPM) is a rare and fatal cancer arising from the mesothelial cells lining the peritoneum. This typically occurs in men in their fifth and sixth decades, but can be seen in women and any age group. Pleural and extrapleural mesothelioma can arise in the setting of asbestos exposure, but other reported causes of MPM include exposure to silicate fibers and radiation therapy. Because it presents with vague symptoms such as abdominal pain, anorexia, and weight loss, it is generally advanced at diagnosis. This is a case of MPM that presented initially at contrast-enhanced computed tomography as a small focal lesion in the lesser sac, ultimately resulting in death from complications of the disease.

    Peritoneal angiosarcoma is an extremely rare sarcoma (0.01287% incidence per 100,000) with an aggressive clinical course and a poor prognosis. We herein report a case of a young man with diagnosis of angiosarcoma whose tumor adhering to the inferior wall of his bladder and omentum was initially thought to be rhabdomyosarcoma. His disease state progressively worsened, despite initiation of different types of chemotherapies. Blood was tested for cytokine and soluble receptor levels. Unexpectedly and never previously reported, very high levels of interleukin-6 (IL-6), osteopontin, and prolactin were found. Surprisingly, angiogenic cytokines levels were low. The patient died 5 months after initial presentation. In the present report, we discuss the difficulties in diagnosing this rare sarcoma and possible therapeutic targets, including the IL-6 pathway that may provide more effective ways in controlling this cancer in its metastatic stage.

    Mesothelioma is a malignancy of the pleura, pericardium and peritoneum that is rarely seen in cutaneous biopsies. We present a case of a 75-year-old man with significant occupational exposure to asbestos who developed peritoneal mesothelioma that presented as a skin nodule in an old appendectomy scar. The patient presented with a complaint of increased hardness along his appendectomy scar. Physical examination revealed an anterior abdominal wall mass overlying the appendectomy scar, which was subsequently biopsied. Histologic examination of the abdominal wall mass revealed an infiltrating epithelioid and papillary neoplasm within the dermis and subcutaneous tissue. Immunohistochemical stains showed immunoreactivity for cytokeratin (CK) 7, CK 5/6, calretinin and vimentin. CK 20, monoclonal carcinoembryonic antigen, prostate-specific antigen and prostate-specific acid phosphatase were negative. The profile supported the diagnosis of mesothelioma. Cutaneous presentation of mesothelioma is rare but should be considered in the differential diagnosis of patients with significant asbestos exposure. PMID:19515047

    Background 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. Method 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. Results 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

    Summary Background and objectives Peritonitis remains as the most frequent cause of peritoneal dialysis (PD) failure, impairing patient's outcome. No large multicenter study has addressed socioeconomic, educational, and geographic issues as peritonitis risk factors in countries with a large geographic area and diverse socioeconomic conditions, such as Brazil. Design, setting, participants, & measurements Incident PD patients recruited from 114 dialysis centers and reporting to BRAZPD, a multicenter observational study, from December 2004 through October 2007 were included. Clinical, dialysis-related, demographic, and socioeconomic variables were analyzed. Patients were followed up until their first peritonitis. Cox proportional model was used to determine independent factors associated with peritonitis. Results In a cumulative follow-up of 2032 patients during 22.026 patient-months, 474 (23.3%) presented a first peritonitis episode. In contrast to earlier findings, PD modality, previous hemodialysis, diabetes, gender, age, and family income were not risk predictors. Factors independently associated with increased hazard risk were lower educational level, non-white race, region where patients live, shorter distance from dialysis center, and lower number of patients per center. Conclusions Educational level and geographic factors as well as race and center size are associated with risk for the first peritonitis, independent of socioeconomic status, PD modality, and comorbidities.

    Background. Encapsulating peritoneal sclerosis (EPS) is a rare but serious complication of peritoneal dialysis (PD). Besides the endothelial-to-mesenchymal transition (EMT), recently peritoneal adipocytes emerged as a potential source of fibrosis. We performed immunohistochemistry to approach EMT and to localize peritoneal adipocytes in peritoneal biopsies from PD-related EPS patients. Material and Methods. We investigated tissue expression of podoplanin, cytokeratin AE1/AE3 (mesothelium), calretinin (adipocytes), alpha-smooth muscle actin [α-SMA] (mesenchymal cells), interstitial mononuclear cell inflammation, and neoangiogenesis (CD3, CD4, CD8, CD20, CD68, and CD31 immunostainings, resp.). Results. Three patients (1 man/2 women; 17, 64, and 39 years old, resp.) developed EPS after 21, 90, and 164 months of PD therapy. In patients with EPS, we observed (1) loss of AE1/AE3 cytokeratin+ mesothelial cells without any evidence of migration into the interstitium, (2) disappearance of adipose tissue, (3) diffuse infiltration of calretinin+ cells in the areas of submesothelial fibrosis with a huge number of α-SMA and calretinin+ fusiform cells, and (4) increased vascular density. Conclusion. We report that the involvement of EMT in peritoneal fibrosis is difficult to demonstrate and that the calretinin+ adipocytes might be an underestimated component and a new source of myofibroblasts in peritoneal remodeling during PD-related EPS.

    Abstract Left ventricular diastolic dysfunction (LVDD) is common among patients undergoing peritoneal dialysis (PD). We examined the relationship between LVDD, major adverse cardiovascular events (MACE), and mortality in PD patients. A total of 149 patients undergoing PD with preserved left ventricular systolic function were included and followed for 3.5 years. LVDD was diagnosed (according to the European Society of Cardiology guidelines) by conventional and tissue Doppler echocardiography. Serum high-sensitivity C-reactive protein (hsCRP) was measured. The location and volume of adipose tissue were assessed by computed tomography (CT) at the level of the fourth lumbar vertebra. Subjects with LVDD had higher levels of hsCRP, and more visceral and peritoneal fat than controls. The relationship between adjusted visceral adipose tissue and LVDD became nonsignificant when hsCRP and baseline demographic data were introduced into the logistic regression model (odds ratio = 1.52, P = 0.07). Subsequent hierarchical multivariate Cox regression analysis showed that LVDD was one of the most powerful determinants of MACE and mortality after adjusting for all confounding factors (hazard ratio [HR]: 1.71, 95% confidence interval [CI]: 1.43–3.51, P = 0.02 and HR: 2.25, 95% CI: 1.45–2.91, P = 0.04, respectively). Systemic inflammation (hsCRP) was also significantly associated with MACE and mortality (HR: 2.03, P = 0.03 and HR: 2.16, P = 0.04, respectively). LVDD is associated with systemic inflammation and increased visceral fat in patients undergoing PD. LVDD is also a sensitive, independent indicator of future MACE and mortality in PD patients.

    In n = 1504 consecutive patients after inpatient cardiac rehabilitation, we investigate how many patients can be motivated to join a so-called outpatient heart group, which sociographical and medical variables influence participation, and whether participation in a heart group prompts a more health-orientated nutrition. Applying a special team-based motivation programme, almost 30% of patients undergoing cardiac rehabilitation under the pension insurance scheme for workers can be motivated to join a heart group, who otherwise can hardly be prompted to do so. About 75% of them still participate in the heart group 7 months later. Initial and continuing participation are more probable in patients of middle age, male gender, with previous PTCA, moderately or severely restricted left ventricular function, and--for patients up to the age of 55 years--in case of reintegration or expected reintegration into work life. Patients after heart valve surgery are significantly less liable to join a heart group than CHD patients. Seven months after cardiac rehabilitation, medium cholesterol values have less increased among participants of heart groups than among non-participants. This may indicate a more stabilized health-orientated lifestyle among members of heart groups. PMID:10413799

    We report a case of peritonitis resulting from colon perforation caused by ingestion of a rare foreign body in a patient on peritoneal dialysis (PD). A 72-year-old woman on PD was hospitalized with abdominal pain and cloudy PD fluid (PDF). Although conventional antibiotic therapy was started because of a diagnosis of infectious peritonitis, low-grade fever, abdominal pain and a high number of white blood cells in PDF persisted. On day 3, anaerobic bacteria were recognized on bacterial culture of PDF, suggesting a gastrointestinal etiology. During exploratory laparotomy, sigmoidal perforation by a piece of bamboo, probably resulting from ingestion of contaminated food, was found. PMID:21879431

    Until recently scientists had limited opportunities to study human cognitive performance in non-laboratory, fully ambulatory situations. Recently, advances in technology have made it possible to extend behavioral assessment to the field environment. One of the first devices to measure human behavior in the field was the wrist-worn actigraph. This device, now widely employed, can acquire minute-by-minute information on an individual"s level of motor activity. Actigraphs can, with reasonable accuracy, distinguish sleep from waking, the most critical and basic aspect of human behavior. However, rapid technologic advances have provided the opportunity to collect much more information from fully ambulatory humans. Our laboratory has developed a series of wrist-worn devices, which are not much larger then a watch, which can assess simple and choice reaction time, vigilance and memory. In addition, the devices can concurrently assess motor activity with much greater temporal resolution then the standard actigraph. Furthermore, they continuously monitor multiple environmental variables including temperature, humidity, sound and light. We have employed these monitors during training and simulated military operations to collect information that would typically be unavailable under such circumstances. In this paper we will describe various versions of the vigilance monitor and how each successive version extended the capabilities of the device. Samples of data from several studies are presented, included studies conducted in harsh field environments during simulated infantry assaults, a Marine Corps Officer training course and mechanized infantry (Stryker) operations. The monitors have been useful for documenting environmental conditions experienced by wearers, studying patterns of sleep and activity and examining the effects of nutritional manipulations on warfighter performance.

    OBJECTIVE Type 2 diabetes is increasingly common and associated with substantial morbidity and mortality. This study examines trends in the patterns and costs of drug treatment of type 2 diabetes from 1997 to 2012. RESEARCH DESIGN AND METHODS We conducted descriptive analyses of cross-sectional data using the IMS Health National Disease and Therapeutic Index, a nationally representative audit of ambulatory physician practices in the U.S. We focused on visits for diabetes among patients 35 years of age or older. We used the IMS Health National Prescription Audit of pharmacy dispensing to derive information about drug expenditures. RESULTS Ambulatory diabetes visits increased from 23 million treatment visits in 1997 (95% CI 21–25) to 35 million (32–37) in 2007 and declined to 31 million visits by 2012 (27–31). Between 1997 and 2012 biguanide use increased, from 23% (20–26) to 53% (50–56) of treatment visits. Glitazone use grew from 6% (4–8) in 1997 (41% [39–43] of all visits in 2005), but declined to 16% (14–18) by 2012. Since 2005, dipeptidyl peptidase-4 (DPP-4) inhibitor use increased steadily, representing 21% (18–23) of treatment visits by 2012. Glucagon-like peptide 1 (GLP-1) agonists accounted for 4% of treatment visits in 2012. Visits where two or more drug compounds were used increased nearly 40% from 1997 to 2012. Between 2008 and 2012, drug expenditures increased 61%, driven primarily by use of insulin glargine and DPP-4 inhibitors. CONCLUSIONS Declining sulfonylurea and glitazone use has been offset by increases in DPP-4 inhibitor use and, to a lesser degree, use of GLP-1 agonists. Treatment of diabetes has grown in complexity while older treatments continue to be replaced or supplemented by newer therapies. PMID:24198301

    Feline infectious peritonitis (FIP) continues to be one of the most researched infectious diseases of cats. The relatively high mortality of FIP, especially for younger cats from catteries and shelters, should be reason enough to stimulate such intense interest. However, it is the complexity of the disease and the grudging manner in which it yields its secrets that most fascinate researchers. Feline leukemia virus infection was conquered in less than two decades and the mysteries of feline immunodeficiency virus were largely unraveled in several years. After a half century, FIP remains one of the last important infections of cats for which we have no single diagnostic test, no vaccine and no definitive explanations for how virus and host interact to cause disease. How can a ubiquitous and largely non-pathogenic enteric coronavirus transform into a highly lethal pathogen? What are the interactions between host and virus that determine both disease form (wet or dry) and outcome (death or resistance)? Why is it so difficult, and perhaps impossible, to develop a vaccine for FIP? What role do genetics play in disease susceptibility? This review will explore research conducted over the last 5 years that attempts to answer these and other questions. Although much has been learned about FIP in the last 5 years, the ultimate answers remain for yet more studies. PMID:24837550

    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. PMID:26550568

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

    Background The relationship between cardiac autonomic nerve activity and blood pressure (BP) changes in ambulatory dogs is unclear. Objective To test the hypotheses that simultaneous termination of stellate ganglion nerve activity (SGNA) and vagal nerve activity (VNA) predisposes to spontaneous orthostatic hypotension and that specific β2 adrenoceptor blockade prevents the hypotensive episodes. Methods We used a radiotransmitter to record SGNA, VNA and blood pressure (BP) in 8 ambulatory dogs. Video imaging was used to document postural changes. Results Out of these 8 dogs, 5 showed simultaneous sympathovagal discharges in which the minute by minute integrated SGNA correlated with integrated VNA in a linear pattern (“Group 1”). In these dogs abrupt termination of simultaneous SGNA-VNA at the time of postural changes (as documented by video imaging) was followed by abrupt (>20 mmHg over 4 beats) drops in BP. Dogs without simultaneous on/off firing (“Group 2”) did not have drastic drops in pressure. ICI 118,551 (ICI, a specific β2-blocker) infused at 3.1 µg/kg/hr for 7 days significantly increased BP from 126 (95% confidence interval, CI: 118 to 133) mmHg to 133 (95% CI 125 to141) mmHg (p=0.0001). The duration of hypotension (mean systolic BP < 100 mmHg) during baseline accounted for 7.1% of the recording. The percentage was reduced by ICI to 1.3% (p = 0.01). Conclusions Abrupt simultaneous termination of SGNA-VNA was observed at the time of orthostatic hypotension in ambulatory dogs. Selective β2 adrenoceptor blockade increased BP and reduced the duration of hypotension in this model. PMID:24275433

    The aim of this study was to assess the role of European ambulatory pediatricians in caring for asthmatic children, especially in terms of their therapeutic education. We developed a survey that was observational, declarative, retrospective and anonymous in nature. 436 ambulatory pediatricians in Belgium, France, Germany, Italy, Luxembourg and Slovenia were asked to participate in the survey providing information on three children over 6 years old suffering from persistent asthma, who had been followed for at least 6 months. We considered the pediatricians' profile, and their role in the therapeutic education of children. 277 pediatricians (64%) responded: 81% were primary care pediatricians; 46% participated in networks; 4% had specific training in Therapeutic Patient Education; 69% followed more than 5 asthmatic children per month, and over long periods (7 ± 4 years). The profiles of 684 children were assessed. Answers diverged concerning the provision of a Personalized Action Plan (60-88%), training the child to measure and interpret his Peak Expiratory Flow (31-99%), and the prescription of pulmonary function tests during the follow-up programme of consultations (62-97%). Answers converged on pediatricians' perception of their role in teaching children about their condition and its treatment (99%), about inhalation techniques (96%), and in improving the children's ability to take preventive measures when faced with risk situations (97%). This study highlights the role of European pediatricians in caring for asthmatic children, and their lack of training in Therapeutic Patient Education. Programmes and tools are required in order to train ambulatory pediatricians in Therapeutic Patient Education, and such resources should be integrated into primary health care, and harmonized at the European level.

    Effective scheduling of and ready access to doctor appointments affect ambulatory patient care quality, but these are often sacrificed by patients seeking care from physicians at academic medical centers. At one center, Beth Israel Deaconess Medical Center, the authors developed interventions to improve the scheduling of appointments and to reduce the access time between telephone call and first offered appointment. Improvements to scheduling included no redirection to voicemail, prompt telephone pickup, courteous service, complete registration, and effective scheduling. Reduced access time meant being offered an appointment with a physician in the appropriate specialty within three working days of the telephone call. Scheduling and access were assessed using monthly "mystery shopper" calls. Mystery shoppers collected data using standardized forms, rated the quality of service, and transcribed their interactions with schedulers. Monthly results were tabulated and discussed with clinical leaders; leaders and frontline staff then developed solutions to detected problems. Eighteen months after the beginning of the intervention (in June 2007), which is ongoing, schedulers had gone from using 60% of their registration skills to over 90%, customer service scores had risen from 2.6 to 4.9 (on a 5-point scale), and average access time had fallen from 12 days to 6 days. The program costs $50,000 per year and has been associated with a 35% increase in ambulatory volume across three years. The authors conclude that academic medical centers can markedly improve the scheduling process and access to care and that these improvements may result in increased ambulatory care volume.

    Preservation of peritoneal membrane (PM) is essential for long-term survival in peritoneal dialysis (PD). Continuous presence of PD fluids (PDF) in the peritoneal cavity generates chronic inflammation and promotes changes of the PM, such as fibrosis, angiogenesis, and lymphangiogenesis. Mesothelial-to-mesenchymal transition (MMT) and endothelial-to-mesenchymal transition (Endo-MT) seem to play a central role in this pathogenesis. We speculated that Rapamycin, a potent immunosuppressor, could be beneficial by regulating blood and lymphatic vessels proliferation. We demonstrate that mice undergoing a combined PD and Rapamycin treatment (PDF + Rapa group) presented a reduced PM thickness and lower number of submesothelial blood and lymphatic vessels, as well as decreased MMT and Endo-MT, comparing with their counterparts exposed to PD alone (PDF group). Peritoneal water transport in the PDF + Rapa group remained at control level, whereas PD effluent levels of VEGF, TGF-β, and TNF-α were lower than in the PDF group. Moreover, the treatment of mesothelial cells with Rapamycin in vitro significantly decreased VEGF synthesis and selectively inhibited the VEGF-C and VEGF-D release when compared with control cells. Thus, Rapamycin has a protective effect on PM in PD through an antifibrotic and antiproliferative effect on blood and lymphatic vessels. Moreover, it inhibits Endo-MT and, at least partially, MMT.

    Cancer pain is progressive and complex. The multidimensional character of cancer pain requires comprehensive management by a multidisciplinary team of health care professionals. Pharmacotherapy is a cornerstone of cancer pain management. Pharmacists who are engaged in ambulatory cancer pain management can play a pivotal role in the pharmacotherapy of cancer pain by optimizing medication therapy, monitoring outcomes, enhancing adherence through patient education regarding drug use, pain and symptom control, educating other health professionals and students, and conducting research. To fully meet the therapeutic challenges of cancer pain, pharmacists need to improve their knowledge and attitudes about cancer pain and pain medications. PMID:12003689

    An ECG signal processor (ESP) is proposed for the low energy wireless ambulatory arrhythmia monitoring system. The ECG processor mainly performs filtering, compression, classification and encryption. The data compression flow consisting of skeleton and modified Huffman coding is the essential function to reduce the transmission energy consumption and the memory capacity, which are the most energy consuming part. The classification flow performs the arrhythmia analysis to alert the abnormality. The proposed ESP IC is implemented in 0.18-microm CMOS process and integrated into the wireless arrhythmia monitoring sensor platform. By integration of the ESP, the total system energy reduction is evaluated by 95.6%. PMID:19963908

Teaching with simulation trains team members to respond to unexpected events and enables them to provide care when an emergency situation arises. Simulation drills resemble clinical practice and allow personnel to apply and integrate skills, teamwork, and critical thinking. This article provides information and tools for performing cardiac simulation drills in the ambulatory setting. Tools included are a 10-step guide to simulation drills, a scenario, roles and duties to assign during a drill, and a drill evaluation form. PMID:24581645

    For ambulatory surgical centers (ASC) to succeed financially, it is critical for ASC managers to schedule surgical procedures in a manner that optimizes operating room (OR) efficiency. OR efficiency is maximized by using historical data to accurately predict future OR workload, thereby enabling OR time to be properly allocated to surgeons. Other strategies to maintain a well-functioning ASC include recruiting and retaining the right staff and ensuring patients and surgeons are satisfied with their experience. This article reviews different types of procedure scheduling systems. Characteristics of well-functioning ASCs are also discussed. PMID:24882135

    We performed divided saphenectomy (DS) for varicose vein in ambulatory surgery with minimal incisions. Under tumescent local anesthesia, this procedure ligates all perforators in the thigh, preserving a route of venous drainage, and reduces bruising by ligating all tributaries. Also, DS does not need any special surgical instrument. Subcutaneous inguinal hemorrhage was observed in 4.9% (3/61), mild bruises were observed in 19.7% (12/61), and saphenous nerve neuralgia was 1.6% (1/61). Wound infection, deep venous thrombosis, and edema were not observed. DS is a minimally invasive, simple, and cost-effective procedure. PMID:24995071

    Triage ambulatory electrocardiographic (ECG) analysis permits relatively unskilled office workers to submit 24-hour ambulatory ECG Holter tapes to an automatic instrument (model 563, Del Mar Avionics, Irvine, CA) for interpretation. The instrument system "triages" what it is capable of automatically interpreting and rejects those tapes (with high ventricular arrhythmia density) requiring thorough analysis. Nevertheless, a trained cardiovascular technician ultimately edits what is accepted for analysis. This study examined the clinical validity of one manufacturer's triage instrumentation with regard to accuracy and time efficiency for interpreting ventricular arrhythmia. A database of 50 Holter tapes stratified for frequency of ventricular ectopic beats (VEBs) was examined by triage, conventional, and full-disclosure hand-count Holter analysis. Half of the tapes were found to be automatically analyzable by the triage method. Comparison of the VEB accuracy of triage versus conventional analysis using the full-disclosure hand count as the standard showed that triage analysis overall appeared as accurate as conventional Holter analysis but had limitations in detecting ventricular tachycardia (VT) runs. Overall sensitivity, positive predictive accuracy, and false positive rate for the triage ambulatory ECG analysis were 96, 99, and 0.9%, respectively, for isolated VEBs, 92, 93, and 7%, respectively, for ventricular couplets, and 48, 93, and 7%, respectively, for VT. Error in VT detection by triage analysis occurred on a single tape. Of the remaining 11 tapes containing VT runs, accuracy was significantly increased, with a sensitivity of 86%, positive predictive accuracy of 90%, and false positive rate of 10%. Stopwatch-recorded time efficiency was carefully logged during both triage and conventional ambulatory ECG analysis and divided into five time phases: secretarial, machine, analysis, editing, and total time. Triage analysis was significantly (P < .05) more time

The capacitive electrodes have conductive foam on their surface, a shield, an optimal input bias resistor, and guarding feedback. The electrodes are integrated in a chest belt, and the acquired signals are transmitted wirelessly for ambulatory heart rate monitoring. We experimentally validated the electrode performance with subjects standing and walking on a treadmill at speeds of up to 7 km/h.

    Caring for the pediatric and adolescent patient in the ambulatory surgery unit is challenging for several reasons. The first 18 years are a period of rapid physical, cognitive, and psychosocial growth. Psychological preparation is very important to ensure the readiness of the child and family for surgery; however, the efficacy of the different methods of preparation varies. Teaching should be geared to the developmental level of the child, and specific information on the process, sights, smells, and sensations the child will experience should be given to allay parental anxiety and fears. Appropriate tools must be available for the nurse to assess and implement the physical plan of care. PMID:9115488

    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. Damage of the intestinal mucosa barrier may result in intestinal bacterial and endotoxin translocation, leading to local and systemic inflammation. The present study was designed to investigate whether peritoneal air exposure induces damage of intestinal mucosal barrier. Methods. Sprague-Dawley rats (weighing 210 to 230 g) were randomized into five groups (6/group): a control group, a sham group, and three exposure groups with peritoneal air exposure for 1, 2, and 3 h, respectively. At 24 h after surgery, blood and terminal ileum were sampled. The serum D-lactate levels were determined using an ELISA kit. The intestinal permeability was determined by measuring the intestinal clearance of FITC-dextran (FD4). The histopathological changes in terminal ileum were also assessed. Results. Compared with the controls, peritoneal air exposure caused an increase in both serum D-lactate level and intestinal FD4 clearance, which were proportional to the length of peritoneal air exposure and correlated to Chiu's scores, indices for intestinal mucosal injury. Edema and inflammatory cells were also observed in mucosa and submucosa of ileum in three exposure groups. Conclusions. Peritoneal air exposure could induce damage to the intestinal mucosal barrier, which is proportional to the time length of peritoneal air exposure. PMID:25210511

    Peritoneal dialysis (PD) is a modality for treatment of patients with end-stage renal disease (ESRD) that depends on the structural and functional integrity of the peritoneal membrane. However, long-term PD can lead to morphological and functional changes in the peritoneum; in particular, peritoneal fibrosis has become one of the most common complications that ultimately results in ultrafiltration failure (UFF) and discontinuation of PD. Several factors and mechanisms such as inflammation and overproduction of transforming growth factor-β1 have been implicated in the development of peritoneal fibrosis, but there is no effective therapy to prevent or delay this process. Recent studies have shown that activation of multiple receptor tyrosine kinases (RTKs) is associated with the development and progression of tissue fibrosis in various organs, and there are also reports indicating the involvement of some RTKs in peritoneal fibrosis. This review will describe the role and mechanisms of RTKs in peritoneal fibrosis and discuss the possibility of using them as therapeutic targets for prevention and treatment of this complication.

    Fungal peritonitis is an uncommon but serious complication of peritoneal dialysis (PD) due to the fact that routine culture to recovered the etiologic agents are time consuming and KOH staining has very low sensitivity. Peritoneal (1→3)-β-D-glucan (BG) or galactomannan (GM), both fungal cell wall components, are candidate biomarkers of fungal peritonitis. Hence, a comparative cross-sectional analysis of peritoneal dialysis fluid (PDF) BG (Fungitell, Cape Cod, MA, USA) and GM (Platelia Aspergillus Ag kits, Bio-rad, France) from all PD patients with and without fungal peritonitis (13 cases, identified by culture), over a 1 year period, was performed. PDF of the fungal peritonitis group showed very high BG (494 ± 19 pg/ml) and high GM (3.41 ± 1.24) similar results were noted in specimens from cases of peritonitis with other causes, especially gram negative bacterial peritonitis. A BG cut-off value at 240 pg/ml and GM at 0.5 showed sensitivity/ specificity at 100%/ 83% and 77%/ 58%, respectively. A concomitantly positive GM reduced the false positive rate of BG from nonfungal peritonitis. In conclusion, BG and GM in peritoneal fluid with provisional cut-off values were applicable as surrogate biomarkers for the diagnosis of fungal peritonitis in PD patients. PMID:25851260

    Outcomes for pediatric peritoneal dialysis (PD) patients are closely related to dialysis adequacy and nutrition, which need to be measured frequently using a number of laboratory parameters. Although the critical meaning of adequacy and nutrition in the long-term prognosis of dialyzed children is well-documented, PD prescriptions are still largely empirical. Our objective was to evaluate nutritional and dialytic parameters in PD children (urea, creatinine, and albumin excretion in dialysate and urine, and daily protein intake); to measure peritoneal equilibration test (PET) results, Kt/V, normalized equivalent of protein nitrogen appearance (nPNA) and nitrogen balance; and to study the correlations between those variables. We performed 59 prospective laboratory measurements in 15 stable PD patients (7 boys; mean age: 6.7 years; age range: 1.1-14.8 years) during 6 months of follow-up. Creatinine, urea, total protein, and albumin were measured in plasma, urine, and dialysate. We calculated PET, Kt/V, daily dietary protein intake (DPI), protein catabolic rate (PCR), and nPNA. All statistical comparisons used the paired t-test, and correlations were calculated by two-way analysis of variance for repeated measures. A value of p < 0.05 was considered significant. The mean 4-hour dialysate-to-plasma ratio (D/P) of creatinine was 0.78 +/- 0.02 at month 0 and 0.74 +/- 0.13 at month 6 [p = nonsignificant (NS)]. The mean final-dialysate-to-initial-dialysate ratio (D/D0) of glucose was 0.35 +/- 0.11 and 0.34 +/- 0.08 at the same intervals (p = NS). The D/P creatinine showed an inverse correlation with patient age and body surface area, and the D/D0 glucose ratio showed a positive correlation with both of those parameters (p < 0.05). Weekly total and residual Kt/V urea were 3.41 +/- 0.86 and 1.49 +/- 1 respectively. The daily DPI was 3.32 +/- 1.05 g/kg, and the daily PCR was 1.32 +/- 0.47 g/kg, showing a positive net protein balance (DPI-PCR = +2 g/kg daily), which was

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

    Objective To predict ambulatory capacity, 1 month after physical therapy following hip fracture surgery. Methods A retrospective chart review was carried out. Patients more than 60 years old, who underwent hip fracture surgery and received physical therapies, were selected (n=548). Age, gender, presence of cognitive dysfunction, combined medical diseases, combined fractures, previous history of hip surgery, prefracture ambulatory capacity, days from the fracture to surgery, type of fracture, type of surgery, presence of postoperative complications, days from the surgery to physical therapy, and total admission period, were collected. Prefracture ambulatory capacity and postoperative ambulatory capacity were classified into non-ambulatory status (NA), ambulation with assistive device (AA), and independent-ambulation without any assistive device (IA). Multiple-logistic regression analysis was performed for the prediction of postoperative ambulatory capacity. Results Age (odds ratio [OR]=0.94 for IA and 0.96 for IA or AA), gender (OR=1.64 for IA and 0.98 for IA or AA), prefracture ambulatory capacity (OR of IA=19.17 for IA; OR of IA=16.72 for IA or AA; OR of AA=1.26 for IA, OR of AA=9.46 for IA or AA), and combined medical disease (OR=2.02) were found to be the factors related to postoperative ambulatory capacity and the prediction model was set up using these four factors. Conclusion Using this model, we can predict the ambulatory capacity following hip fracture surgery. Further prospective studies should be constructed to improve postoperative ambulatory capacity.

    2013-01-01

    Background Oxidative stress (OS) related to glucose degradation products such as methylglyoxal is reportedly associated with peritoneal deterioration in patients treated with peritoneal dialysis (PD). However, the use of general antioxidant agents is limited due to their harmful effects. This study aimed to clarify the influence of the novel antioxidant molecular hydrogen (H2) on peritoneal OS using albumin redox state as a marker. Methods Effluent and blood samples of 6 regular PD patients were obtained during the peritoneal equilibrium test using standard dialysate and hydrogen-enriched dialysate. The redox state of albumin in effluent and blood was determined using high-performance liquid chromatography. Results Mean proportion of reduced albumin (ƒ(HMA)) in effluent was significantly higher in H2-enriched dialysate (62.31 ± 11.10%) than in standard dialysate (54.70 ± 13.08%). Likewise, serum ƒ(HMA) after administration of hydrogen-enriched dialysate (65.75 ± 7.52%) was significantly higher than that after standard dialysate (62.44 ± 7.66%). Conclusions Trans-peritoneal administration of H2 reduces peritoneal and systemic OS. PMID:23816239

    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

    Wearable monitoring devices are a promising trend for ambulatory and real time biosignal processing, because they improve access and coverage by means of comfortable sensors, with real-time communication via mobile networks. In this paper, we present a garment for ambulatory electrocardiogram monitoring, a smart t-shirt with a textile electrode that conducts electricity and has a coating designed to preserve the user's hygiene, allowing long-term mobile measurements. Silicon dioxide nanoparticles were applied on the surface of the textile electrodes to preserve conductivity and impart superhydrophobic properties. A model to explain these results is proposed. The best result of this study is obtained when the contact angles between the fluid and the fabric exceeded 150°, while the electrical resistivity remained below 5 Ω·cm, allowing an acquisition of high quality electrocardiograms in moving patients. Thus, this tool represents an interesting alternative for medium and long-term measurements, preserving the textile feeling of clothing and working under motion conditions. PMID:24110070

    The standard treatment for ambulatory patients with venous ulcers is compression therapy. The aim of the present study was to develop a warming regimen to treat venous ulcers, which could be easily used by patients in their home or work environment. Five patients with a mean age of 66 years (51-80) who had venous ulcers for an average of 8 months (3-13) were treated with zip-up compression stockings (gradient compression 40 mmHg at the ankle) and a warming dressing. The latter was controlled by the patient to warm the ulcer to 38 degrees C for 1 hour three times daily. Warming therapy was carried out for 2 weeks and patients' ulcers were monitored for healing for 12 weeks. In all but one of the patients following warming therapy, there was marked increase in granulation tissue as well as a decrease in pain. Four of the five patients completely healed during the 12-week period. In conclusion, this study has demonstrated that warming therapy can be used by ambulatory patients with venous ulcers in conjunction with compression therapy. A randomized prospective study is in progress. PMID:10655876

    Blood pressure has traditionally been measured in the clinic setting using the auscultory method and a mercury sphygmomanometer. Technological advances have led to improvements in measuring clinic blood pressure and allowed for measuring blood pressures outside the clinic. This review outlines various methods for evaluating blood pressure and the clinical utility of each type of measurement. Home blood pressures and 24 hour ambulatory blood pressures have improved our ability to evaluate risk for target organ damage and hypertension related morbidity and mortality. Measuring home blood pressures may lead to more active participation in health care by patients and has the potential to improve blood pressure control. Ambulatory blood pressure monitoring enables the measuring nighttime blood pressures and diurnal changes, which may be the most accurate predictors of risk associated with elevated blood pressure. Additionally, reducing nighttime blood pressure is feasible and may be an important component of effective antihypertensive therapy. Finally, estimating central aortic pressures and pulse wave velocity are two of the newer methods for assessing blood pressure and hypertension related target organ damage. PMID:22521624

    Many experts now believe that pervasive problems in affect regulation constitute the central area of dysfunction in borderline personality disorder (BPD). However, data is sparse and inconclusive. We hypothesized that patients with BPD, in contrast to healthy gender and nationality-matched controls, show a higher frequency and intensity of self-reported emotions, altered physiological indices of emotions, more complex emotions and greater problems in identifying specific emotions. We took a 24-hour psychophysiological ambulatory monitoring approach to investigate affect regulation during everyday life in 50 patients with BPD and in 50 healthy controls. To provide a typical and unmanipulated sample, we included only patients who were currently in treatment and did not alter their medication schedule. BPD patients reported more negative emotions, fewer positive emotions, and a greater intensity of negative emotions. A subgroup of non-medicated BPD patients manifested higher values of additional heart rate. Additional heart rate is that part of a heart rate increase that does not directly result from metabolic activity, and is used as an indicator of emotional reactivity. Borderline participants were more likely to report the concurrent presence of more than one emotion, and those patients who just started treatment in particular had greater problems in identifying specific emotions. Our findings during naturalistic ambulatory assessment support emotional dysregulation in BPD as defined by the biosocial theory of [Linehan, M.M., 1993. Cognitive-Behavioral Treatment of Borderline Personality Disorder. The Guildford Press, New York.] and suggest the potential utility for evaluating treatment outcome. PMID:17321599

    2014-01-01

    Day surgery, coming to and leaving the hospital on the same day as surgery as well as ambulatory surgery, leaving hospital within twenty-three hours is increasingly being adopted. There are several potential benefits associated with the avoidance of in-hospital care. Early discharge demands a rapid recovery and low incidence and intensity of surgery and anaesthesia related side-effects; such as pain, nausea and fatigue. Patients must be fit enough and symptom intensity so low that self-care is feasible in order to secure quality of care. Preventive multi-modal analgesia has become the gold standard. Administering paracetamol, NSIADs prior to start of surgery and decreasing the noxious influx by the use of local anaesthetics by peripheral block or infiltration in surgical field prior to incision and at wound closure in combination with intra-operative fast acting opioid analgesics, e.g., remifentanil, have become standard of care. Single preoperative 0.1 mg/kg dose dexamethasone has a combined action, anti-emetic and provides enhanced analgesia. Additional α-2-agonists and/or gabapentin or pregabalin may be used in addition to facilitate the pain management if patients are at risk for more pronounced pain. Paracetamol, NSAIDs and rescue oral opioid is the basic concept for self-care during the first 3–5 days after common day/ambulatory surgical procedures. PMID:25061796

The policlinics' net reduced by 2.25 times, including by 10.6 times in rural area and by 12.6 times of ambulatories of community hospitals. The indicators of physicians' supply of oblast population decreased too especially in urban area. The annual number of visits to physicians per capita decreased by 1.36 times. The number of calls of out-patients to physicians of emergency medical care increased by 1.5 times. The morbidity with temporarily disability and primary registration as a disabled person decreased by 1.45 times, including able-bodied citizen by 1.54 times. In Nizhny Novgorod oblast, the rate of decrease of indicators of primary disability during 2006-2009 overpassed the corresponding federal indicators by 1.45 times. The population mortality increased by 1.43 times. The accessibility and quality of ambulatory polyclinic care significantly impacts on the levels of mortality and social security of population and can be used as an indicator of social risks in the region.

  16. 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. PMID:24569616

    Feline coronavirus (FCoV) infections are endemic among cats worldwide. The majority of infections are asymptomatic or result in only mild enteric disease. However, approximately 5 % of cases develop feline infectious peritonitis (FIP), a systemic disease that is a frequent cause of death in young cats. In this study, we report the complete coding genome sequences of six FCoVs: three from faecal samples from healthy cats and three from tissue lesion samples from cats with confirmed FIP. The six samples were obtained over a period of 8 weeks at a single-site cat rescue and rehoming centre in the UK. We found amino acid differences located at 44 positions across an alignment of the six virus translatomes and, at 21 of these positions, the differences fully or partially discriminated between the genomes derived from the faecal samples and the genomes derived from the tissue lesion samples. In this study, two amino acid differences fully discriminated the two classes of genomes: these were both located in the S2 domain of the virus surface glycoprotein gene. We also identified deletions in the 3c protein ORF of genomes from two of the FIP samples. Our results support previous studies that implicate S protein mutations in the pathogenesis of FIP.

    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. PMID:25482087

We also identified deletions in the 3c protein ORF of genomes from two of the FIP samples. Our results support previous studies that implicate S protein mutations in the pathogenesis of FIP.

    Patient satisfaction is an important aspect of dialysis care, only recently evaluated in clinical studies. We developed a tool to assess peritoneal dialysis (PD) customer satisfaction, and sought to evaluate and validate the Customer Satisfaction Questionnaire (CSQ), quantifying PD patient satisfaction. The CSQ included questions regarding administrative issues, Delivery Service, PD Training, Handling Requests, and transportation. The study was performed using interviews in all Hungarian Fresenius Medical Care dialysis centers offering PD. CSQ results were compared with psychosocial measures to identify if patient satisfaction was associated with perception of social support and illness burden, or depression. We assessed CSQ internal consistency and validity. Factor analysis explored potential underlying dimensions of the CSQ. One hundred and thirty-three patients treated with PD for end-stage renal disease for more than 3 months were interviewed. The CSQ had high internal consistency. There was high patient satisfaction with customer service. PD patient satisfaction scores correlated with quality of life (QOL) and social support measures, but not with medical or demographic factors, or depressive affect. The CSQ is a reliable tool to assess PD customer satisfaction. PD patient satisfaction is associated with perception of QOL. Efforts to improve customer satisfaction may improve PD patients' quantity as well as QOL. PMID:16900092

    This article reports on the clinical practice guidelines developed by a multidisciplinary group working on the indications and uses of the various available treatment options for relieving intestinal obstruction or its symptoms in patients with peritoneal carcinomatosis. These guidelines are based on a literature review and expert opinion. The recommended strategy involves a clinical and radiological evaluation, of which CT of the abdomen is a crucial component. The results, together with an analysis of the prognostic criteria, are used to determine whether surgery or stenting is the best option. In most patients, however, neither option is feasible, and the main emphasis, therefore, is on the role and administration of various symptomatic medications such as glucocorticoids, antiemetic agents, analgesics, and antisecretory agents (anticholinergic drugs, somatostatin analogues, and proton-pump inhibitors). Nasogastric tube feeding is no longer used routinely and should instead be discussed on a case-by-case basis. Recent studies have confirmed the efficacy of somatostatin analogues in relieving obstruction-related symptoms such as nausea, vomiting, and pain. However, the absence of a marketing license and the high cost of these drugs limit their use as the first-line treatment, except in highly selected patients (early recurrence). When these medications fail to alleviate the symptoms of obstruction, venting gastrostomy should be considered promptly. Rehydration is needed for virtually every patient. Parenteral nutrition and pain management should be adjusted according to the patient needs and guidelines. PMID:24798105

    After many decades of evolution and with many choices available for the formulation of peritoneal dialysis fluids (PDF), we find ourselves at a crossroads. A review of related developments, laboratory trials and clinical evaluations is offered to stimulate future research in this area. The information presented here raises more questions than it provides answers, but opens the door to innumerable possibilities for improvement. The search for a biocompatible osmotic agent designed to replace those currently used has been frustrating and is far from being considered a success. Research on cytokines and other mediators of inflammation produced a huge amount of interesting scientific knowledge that may help our understanding. However, it is unlikely that it will identify a specifically targeted anticytokine, or combination of them, designed to neutralize and/or reverse inflammatory changes resulting from the use of poorly biocompatible PDF. The development of low glucose degradation product (GDP) solutions by means of multi-chambered bags appear to be a step in the right direction and perhaps is the most significant improvement in this field in many decades. GDPs are important, but not the only offenders or the exclusive source of oxidative stress. Thus, the addition of antioxidants to PDF formulations, in our opinion, deserves further consideration. Additionally, repopulation of the mesothelial monolayer by means of periodic autotransplantation of mesothelial cells may well become a useful tool to prevent and/or correct membrane failure. We are fortunate to have choices at this crossroad, which we must evaluate rigorously. PMID:16767068

    To investigate the neurotrophic properties of endometriosis, as well as the involvement of neurotrophic factors in the development of chronic pelvic pain in patients with endometriosis, we performed a prospective clinical study. The presence of neurotrophins was investigated in the peritoneal fluid (PF) of patients with peritoneal endometriotic lesions or adenomyosis, as well as from women with non-endometriotic adhesions and from women without endometriosis/adenomyosis/adhesions. The PF from patients with peritoneal endometriotic lesions was divided in three groups: asymptomatic endometriosis, minimal pain and severe pain. PF from patients with adenomyosis or with non-endometriotic adhesions and the control group were divided in patients without pain and with pain. Neurotrophin expression in PF was analyzed using Elisa and the neuronal growth assay with cultured chicken sensory ganglia (dorsal-root-ganglia, DRG) and sympathetic ganglia. PF from women with peritoneal endometriotic lesions overexpress nerve growth factor (NGF) and neurotrophin-3 (NT-3), but not brain derived neurotrophic factor (BDNF), whereas the PF of women with adenomyosis or adhesions seems to express normal amounts of these factors. Neurotrophin expression did not differ among the pain groups. Furthermore, the PF from patients with peritoneal endometriotic lesions induced a strong sensory and a marginal sympathetic neurite outgrowth, while the PF from women with adenomyosis and non-endometriotic adhesions induced an outgrowth similar to the control group. The induced neurite outgrowth could only be inhibited in DRG incubated with peritoneal endometriotic lesions. Interestingly, the outgrowth of sympathetic ganglia was inhibited in all studied groups. The present study suggests that only peritoneal endometriotic lesions lead to an increased release of NGF and NT-3 into the PF and that NGF modulates the nerve fiber growth in endometriosis.

    Background. Icodextrin is a glucose polymer derived by hydrolysis of cornstarch. The different biocompatibility profile of icodextrin-containing peritoneal dialysis (PD) solutions may have a positive influence on peritoneal host defence. Furthermore, cases of sterile peritonitis potentially associated with icodextrin have been reported. Methods. The primary objective of this multicentre, longitudinal, observational, non-interventional, prospective cohort study, which included 722 PD patients, was to evaluate the incidence of overall peritonitis in patients treated with icodextrin-containing PD solutions (Extraneal™) used during one long-dwell exchange/day compared with those treated with non-icodextrin-containing PD solutions. The secondary objective was to determine if culture-negative peritonitis rates differed between patients treated with icodextrin from two independent manufacturers. All peritonitis episodes were assessed by a Steering Committee in a blind manner. Results. There was no significant difference between icodextrin-treated and control patients in the adjusted overall, culture-positive or culture-negative peritonitis rates. When stratified by the icodextrin supplier, there was no significant difference in the adjusted rate of culture-negative peritonitis episodes between groups. Conclusion. Subjects receiving icodextrin as part of their PD regimen experienced neither a higher rate of culture-negative peritonitis nor a lower rate of infectious peritonitis compared with non-icodextrin users. There was no significant influence of the icodextrin raw material supplier on peritonitis rates. PMID:18556747

    A 78-year-old female undergoing peritoneal dialysis due to chronic renal failure was admitted to our hospital because of a tumor on her right chest wall. The diagnosis was recurrence of hepatocellular carcinoma in the thoracic wall, and a combined resection of the thoracic wall and diaphragm was performed. Peritoneal dialysis was resumed 7 days after surgery, but a right pleural effusion was observed after 6 days of dialysis. Surgery was performed because failure of sutures related to the excised diaphragm was suspected. A thoracotomy revealed a large defect, about 1 cm in size, caused by injury of the diaphragm by an edge of the resected rib at the another site of a previous resection of the diaphragm. This defect was closed with sutures and the diaphragm was reinforced with a polyglycolic acid felt and fibrin glue. Peritoneal dialysis was resumed 7 days after surgery and has continued to date without recurrence. PMID:19764505

    Three factors are coinciding to reshape the ambulatory care market: chronic disease prevalence, workforce shortages, and the availability of cell phone technology with very high consumer penetration. These factors will disproportionately drive the business strategies and practices of ambulatory care providers, payers, and delivery systems this decade. Market dynamics are driving the healthcare industry to adopt new strategies to deal with the swelling prevalence of chronic disease. Healthcare organizations are constrained by money and inadequate tools to systematically manage chronic care patients. As a result, traditional notions of ambulatory care are changing from being provider-centered to becoming more patient-centric. A host of new remote monitoring and communication technologies are available so that providers can now interact with patients "anywhere, anytime." The traditional care setting is shifting to where the patient is rather than where the physician is located. Patients are the most underutilized resource in healthcare, and patient engagement is the key to managing chronic illness. Cell phones are particularly suited for leveraging the time and expertise of providers while engaging patients in their own self-care. To demonstrate this concept, data are presented that illustrate how cell phone applications significantly reduced the cost of treating severely asthmatic children and teens in 2 ways: through more frequent communication between patients and their medical teams, and by motivating patients to become more engaged and knowledgeable about their care. The healthcare industry can support consumer choice by making available as many options as possible for engaging patients in their care. Consumers like having choices and patients are no different: they are not all one type. This suggests an emerging role for cell phone applications and platforms that enable both Internet and medical device connectivity where appropriate for managing chronic

    AIM: To validate the sleep-disordered breathing components of a portable electrocardiography and hemodynamic monitor to be used for sleep apnea screening. METHODS: Sleep-disordered breathing (SDB) is associated with cardiovascular disease. Patients with existing cardiovascular disease may have unrecognized SDB or may develop SDB while under the care of a cardiologist. A screening device for SDB, easy to use and appealing to cardiologists, would assist in referral of appropriate patients for full polysomnography (PSG). A cardiac and respiratory monitor (CPAM) was attached to patients undergoing PSG and an apnea/hypopnea index (AHI) generated. The CPAM device produced respiration rate, snoring rate, individual apnea/hypopnea events and an SDB severity score (SDBSS). In addition to AHI, an expert over-reader annotated individual breaths, snores and SDB breathing events to which the automated algorithms were compared. RESULTS: The test set consisted of data from 85 patients (age: 50.5 ± 12.4 years). Of these, 57 had a positive PSG defined as AHI ≥ 5.0 (mean: 30.0 ± 29.8, negative group mean: 1.5 ± 1.2). The sensitivity and specificity of the SDBSS compared to AHI was 57.9% and 89.3%, respectively. The correlation of snoring rate by CPAM compared to the expert over-reader was r = 0.58 (mean error: 1.52 snores/min), while the automated respiration rate had a correlation of r = 0.90 (mean error: 0.70 breaths/min). CONCLUSION: This performance assessment shows that CPAM can be a useful portable monitor for screening and follow-up of subjects for SDB. PMID:22558491

    Severe hypoxemia refractory to pulmonary mechanical ventilation remains life-threatening in critically ill patients. Peritoneal ventilation has long been desired for extrapulmonary oxygenation owing to easy access of the peritoneal cavity for catheterization and the relative safety compared to an extracorporeal circuit. Unfortunately, prior attempts involving direct oxygen ventilation or aqueous perfusates of fluorocarbons or hemoglobin carriers have failed, leading many researchers to abandon the method. We attribute these prior failures to limited mass transfer of oxygen to the peritoneum and have designed an oxygen formulation that overcomes this limitation. Using phospholipid-coated oxygen microbubbles (OMBs), we demonstrate 100% survival for rats experiencing acute lung trauma to at least 2 h. In contrast, all untreated rats and rats treated with peritoneal oxygenated saline died within 30 min. For rats treated with OMBs, hemoglobin saturation and heart rate were at normal levels over the 2-h timeframe. Peritoneal oxygenation with OMBs was therefore shown to be safe and effective, and the method requires less equipment and technical expertise than initiating and maintaining an extracorporeal circuit. Further translation of peritoneal oxygenation with OMBs may provide therapy for acute respiratory distress syndrome arising from trauma, sepsis, pneumonia, aspiration, burns and other pulmonary diseases.

    Hydrothorax as a complication of peritoneal dialysis (PD) is a rare but recognized event. Proposed mechanisms for the development of a pleuro-peritoneal communication include congenital diaphragmatic defects, acquired weakening of diaphragmatic fibers caused by high intra-abdominal pressures during peritoneal dialysis, and impairments in lymphatic drainage. Pleural fluid analysis and diagnostic imaging assist in differentiation from other causes of pleural effusion. Nearly 50% of patients with this diagnosis have resolution of hydrothorax after temporary cessation of PD with interim hemodialysis for 2-6 weeks. Historically, other treatment options have included conventional pleurodesis and open thoracotomy with direct repair, producing variable results. With the advent of video-assisted thoracoscopy (VATS), surgical repairs and pleurodesis are now frequently performed under direct visualization with minimal invasiveness. We report a case of hydrothorax in a patient after recent introduction to peritoneal dialysis. Pleuro-peritoneal communication was documented with thoracentesis and radionuclide scanning. VATS pleurodesis with talc was performed. Repeat scintigraphy performed 1 week after the procedure revealed no residual communication, and patient was able to resume PD without further complications.

    During the standard heat sterilization process of the lactate–buffered peritoneal dialysis solutions, glucose (an osmotic active substance) degrades to form compounds called glucose degradation products which are cytotoxic and affect the survival of the peritoneal membrane. This case presentation is based on an observation of 224 aseptic peritonitis cases of unknown etiology. For the purpose of clarification, we analyzed the peritoneal dialysis solutions for the presence of acetaldehyde by using a developed and validated high-performance liquid chromatography (HPLC) pre-column derivitazation. The method was validated with respect to validation factors such as linearity, precision, recovery and (LOD). The acetaldehyde level of solutions before heat sterilization was 1.78 ± 2.7 ppm whereas in samples after heat sterilization was about 20 ± 2.07 ppm. Based on the forementioned findings, we hypothesized that the higher levels of acetaldehyde and possibly the other glucose degradation products may have been an etiological factor in these 224 cases of chemical peritonitis. So it is important for the manufacturers to carefully review the heat of sterilization process in the production line. PMID:24363689

    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

    Introduction Over the years various therapeutic techniques for diverticulitis have been developed. Laparoscopic peritoneal lavage (LPL) appears to be a safe and useful treatment, and it could be an effective alternative to colonic resection in emergency surgery. Aim This prospective observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage in perforated sigmoid diverticulitis. Material and methods We surgically treated 70 patients urgently for complicated sigmoid diverticulitis. Thirty-two (45.7%) patients underwent resection of the sigmoid colon and creation of a colostomy (Hartmann technique); 21 (30%) patients underwent peritoneal laparoscopic lavage; 4 (5.7%) patients underwent colostomy by the Mikulicz technique; and the remaining 13 (18.6%) patients underwent resection of the sigmoid colon and creation of a colorectal anastomosis with a protective ileostomy. Results The 66 patients examined were divided into 3 groups: 32 patients were treated with urgent surgery according to the Hartmann procedure; 13 patients were treated with resection and colorectal anastomosis; 21 patients were treated urgently with laparoscopic peritoneal lavage. We had no intraoperative complications. The overall mortality was 4.3% (3 patients). In the LPL group the morbidity rate was 33.3%. Conclusions Currently it cannot be said that LPL is better in terms of mortality and morbidity than colonic resection. These data may, however, be proven wrong by greater attention in the selection of patients to undergo laparoscopic peritoneal lavage. PMID:27458487

    Epithelial ovarian cancer (EOC) is the leading cause of death from gynecologic malignancy in the United States. Mortality is due to diagnosis of 75% of women with late stage disease, when metastasis is already present. EOC is characterized by diffuse and widely disseminated intra-peritoneal metastasis. Cells shed from the primary tumor anchor in the mesothelium that lines the peritoneal cavity as well as in the omentum, resulting in multi-focal metastasis, often in the presence of peritoneal ascites. Efforts in our laboratory are directed at a more detailed understanding of factors that regulate EOC metastatic success. However, quantifying metastatic tumor burden represents a significant technical challenge due to the large number, small size and broad distribution of lesions throughout the peritoneum. Herein we describe a method for analysis of EOC metastasis using cells labeled with red fluorescent protein (RFP) coupled with in vivo multispectral imaging. Following intra-peritoneal injection of RFP-labelled tumor cells, mice are imaged weekly until time of sacrifice. At this time, the peritoneal cavity is surgically exposed and organs are imaged in situ. Dissected organs are then placed on a labeled transparent template and imaged ex vivo. Removal of tissue auto-fluorescence during image processing using multispectral unmixing enables accurate quantitation of relative tumor burden. This method has utility in a variety of applications including therapeutic studies to evaluate compounds that may inhibit metastasis and thereby improve overall survival. PMID:27500635

    Success in the provision of ambulatory personal health services, i.e. providing individuals with treatment for acute illness and preventive health care on an ambulatory basis, is the most significant contributor to the health care system's performance in most developing countries. Ambulatory personal health care has the potential to contribute the largest immediate gains in health status in populations, especially for the poor. At present, such health care accounts for the largest share of the total health expenditure in most lower income countries. It frequently comprises the largest share of the financial burden on households associated with health care consumption, which is typically regressively distributed. The "organization" of ambulatory personal health services is a critical determinant of the health system's performance which, at present, is poorly understood and insufficiently considered in policies and programmes for reforming health care systems. This article begins with a brief analysis of the importance of ambulatory care in the overall health system performance and this is followed by a summary of the inadequate global data on ambulatory care organization. It then defines the concept of "macro organization of health care" at a system level. Outlined also is a framework for analysing the organization of health care services and the major pathways through which the organization of ambulatory personal health care services can affect system performance. Examples of recent policy interventions to influence primary care organization--both government and nongovernmental providers and market structure--are reviewed. It is argued that the characteristics of health care markets in developing countries and of most primary care goods result in relatively diverse and competitive environments for ambulatory care services, compared with other types of health care. Therefore, governments will be required to use a variety of approaches beyond direct public provision

    ♦ Objective: In a number of patients, the antidiabetic drug metformin has been associated with lactic acidosis. Despite the fact that diabetes mellitus is the most common cause of end-stage renal disease (ESRD) and that peritoneal dialysis (PD) is an expanding modality of treatment, little is known about optimal treatment strategies in the large group of PD patients with diabetes. In patients with ESRD, the use of metformin has been limited because of the perceived risk of lactic acidosis or severe hypoglycemia. However, metformin use is likely to be beneficial, and PD might itself be a safeguard against the alleged complications. ♦ Methods: Our study involved 35 patients with insulin-dependent type 2 diabetes [median age: 54 years; interquartile range (IQR): 47-59 years] on automated PD (APD) therapy. Patients with additional risk factors for lactic acidosis were excluded. Metformin was introduced at a daily dose in the range 0.5 - 1.0 g. All patients were monitored for glycemic control by blood sugar levels and HbA1c. Plasma lactic acid levels were measured weekly for 4 weeks and then monthly to the end of the study. Plasma and effluent metformin and plasma lactate levels were measured simultaneously. ♦ Results: In this cohort, the median duration of diabetes was 18 years (IQR: 14 - 21 years), median time on PD was 31 months (IQR: 27 - 36 months), and median HbA1c was 6.8% (IQR: 5.9% - 6.9%). At metformin introduction and at the end of the study, the median anion gap was 11 mmol/L (IQR: 9 - 16 mmol/L) and 12 mmol/L (IQR: 9 - 16 mmol/L; p > 0.05) respectively, median pH was 7.33 (IQR: 7.32 - 7.36) and 7.34 (IQR: 7.32 - 7.36, p > 0.05) respectively, and mean metformin concentration in plasma and peritoneal fluid was 2.57 ± 1.49 mg/L and 2.83 ± 1.7 mg/L respectively. In the group overall, mean lactate was 1.39 ± 0.61 mmol/L, and hyperlactemia (>2 mmol/L to 5 mmol/L) was found in 4 of 525 plasma samples (0.76%), but the patients presented no symptoms. None

    2009-09-01

    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

    Demand for ambulatory care visits is projected to increase 22% between 2008 and 2025. Given this growth, ambulatory care managers need to proactively plan for efficient use of scarce resources (ie, space, equipment, and staff). One important component of ambulatory care space (the number of examination rooms) is dependent on multiple factors, including variation in demand, hours of operation, scheduling, and staff. The authors (1) outline common data collection methods, (2) highlight analysis and reporting considerations for examination room utilization, and (3) provide a strategic framework for short- and long-term decision making for facility design or renovation.

    The self-report symptom inventory, SCL-90-R, was administered to 240 heroin addicts seeking ambulatory detoxification and 240 requesting methadone maintenance. Controlling for age, a stepwise discriminant analysis employing a backward elimination model was performed with the SCL-90-R's nine symptom factors to determine if the addicts described different levels of symptomatology. Interpersonal sensitivity and depression differentiated between the two groups; the ambulatory detoxification patients were more depressed and described less interpersonal sensitivity than the methadone maintenance patients. The results supported the contention that heroin addicts seeking ambulatory detoxification or methadone maintenance may display different symptoms. PMID:7128452

    Historically, analysis of patient service time (patient tracking) in ambulatory clinics has been performed manually. A case study of Eye and Ear Clinic in Pittsburgh, PA, revealed that this approach to patient data collection was prone to clerical error and did not satisfy the clinic's information-processing needs. Initial attempts at automation identified the features required of a successful computerized scheduling and patient tracking system. These essential features are being designed into a prototype system using a local area network platform. The software for this system employs bar code technology to log patients' movement. The resultant data permits analysis of clinic operation and rapid response to unforseen events. Patient information is presented in a color-coded format to permit-at-a-glance comprehension of data on multiple patients (up to 76) simultaneously. A scheduling module projects patients' arrival time and ensures availability of critical resources.

    We describe the current use and future promise of an innovative methodology, ambulatory assessment (AA), that can be used to investigate psychological, emotional, behavioral, and biological processes of individuals in their daily life. The term AA encompasses a wide range of methods used to study people in their natural environment, including momentary self-report, observational, and physiological. We emphasize applications of AA that integrate two or more of these methods, discuss the smart phone as a hub or access point for AA, and discuss future applications of AA methodology to the science of psychology. We pay particular attention to the development and application of Wireless Body Area Networks (WBANs) that can be implemented with smart phones and wireless physiological monitoring devices, and we close by discussing future applications of this approach to matters relevant to psychological science.

    Ambulatory electrocardiogram (ECG) monitoring can effectively reduce the risk and death rate of patients with cardiovascular diseases (CVDs). The Body Sensor Network (BSN) based ECG monitoring is a new and efficien method to protect the CVDs patients. To meet the challenges of miniaturization, low power and high signal quality of the node, we proposed a novel 50 mmX 50 mmX 10 mm, 30 g wireless ECG node, which includes the single-chip an alog front-end AD8232, ultra-low power microprocessor MSP430F1611 and Bluetooth module HM-11. The ECG signal quality is guaranteed by the on-line digital filtering. The difference threshold algorithm results in accuracy of R-wave detection and heart rate. Experiments were carried out to test the node and the results showed that the pro posed node reached the design target, and it has great potential in application of wireless ECG monitoring.

    This study assessed the sociodemographic characteristics and the characteristics of therapeutic adhesion of 27 bearers of arterial hypertension undergoing ambulatorial treatment who had hypertensive urgencies crises or emergencies in the city of Fortaleza in the period between October of 2002 and May of 2003. The majority were women, between 50 and 60-years old, with little formal education, treatment time shorter than 5 years and time of diagnosis varying from 5 to 10 years. The use of medicine was the treatment that was most mentioned, followed by the reduction of the consumption of salt and attendance to medical appointments. However, attending the appointments and receiving orientation did not seem to change their behavior, since most of the patients that were interviewed practiced no physical exercises and demonstrated little knowledge of the illness, for they attributed the rise of the arterial pressure to emotional factors.

    Computers are a ubiquitous part of the ambulatory health care environment. Although stand-alone computers may be adequate for a small practice, networked computers can create much more powerful and cost-effective computerized systems. Local area networks allow groups of computers to share peripheral devices and computerized information within an office or cluster of offices. Wide area networks allow computers to securely share devices and information across a large geographical area. Either singly or in combination, these networks can be used to create robust systems to help physicians automate their practices and improve their access to important clinical information. In this article, we will examine common network configurations, explain how they function, and provide examples of real-world implementations of networking technology in health care. PMID:10662271

    Indicators of the performance of clinical preventive services (CPS) have been adopted in the ambulatory setting to improve quality of care. The impact of CPS was evaluated in a network of 49 primary care practices providing care to an estimated 245,000 adults in the Dallas–Fort Worth area through a sample chart review to determine delivery of recommended evidence-based CPS combined with medical literature estimates of the effectiveness of CPS. In this population in 2005, CPS were estimated to have prevented 36 deaths and 97 incident cases of cancer; 420 coronary heart disease events (including 66 sudden deaths) and 118 strokes; 816 cases of influenza and pneumonia (including 24 hospital admissions); and 87 osteoporosis-related fractures. Thus, CPS have substantial benefits in preventing deaths and illness episodes. PMID:18628969

    Out-of-office blood pressure (BP) monitoring is becoming increasingly important in the diagnosis and management of hypertension. Home BP and ambulatory BP monitoring (ABPM) are the two forms of monitoring BP in the out-of-office environment. Home BP monitoring is easy to perform, inexpensive, and engages patients in the care of their hypertension. Although ABPM is expensive and not widely available, it remains the gold standard for diagnosing hypertension. Observational studies show that both home BP and ABPM are stronger predictors of hypertension-related outcomes than office BP monitoring. There are no clinical trials showing their superiority over office BP monitoring in guiding the treatment of hypertension, but the consistency of observational data make a compelling case for their preferential use in clinical practice.

  8. Clinical Implications of Ambulatory and Home Blood Pressure Monitoring

    PubMed Central

    2010-01-01

    Because blood pressure (BP) is an ever changing hemodynamic phenomenon, a BP value, once measured at a physician's office (Office BP), is often unrepresentative of an individual's true BP status. Both ambulatory blood pressure monitoring (ABPM) and home blood pressure monitoring (HBPM) provide more accurate and reproducible estimate of BP, and produce stronger predictive ability for cardiovascular outcome than conventional office BP. Two BP measuring techniques, ABPM and HBPM have been widely in clinical use for the detection and management of hypertension. However, they have different advantages and limitations in practice. At present, it has become crucial to understand the characteristics and clinical implications of these BP measuring techniques for those responsible for the care of hypertensive patients.

    Pediatricians play a key role in the healthy development of children. Nevertheless, the practice patterns of pediatricians have seldom been investigated. The current study analyzed the nationwide profiles of ambulatory visits to pediatricians in Taiwan, using the National Health Insurance Research Database. From a dataset that was randomly sampled one out of every 500 records among a total of 309,880,000 visits in 2012 in the country, 9.8% (n = 60,717) of the visits were found paid to pediatricians. Children and adolescents accounted for only 69.3% of the visits to pediatricians. Male pediatricians provided 80.5% of the services and the main workforces were those aged 40–49 years. The most frequent diagnoses were respiratory tract diseases (64.7%) and anti-histamine agents were prescribed in 48.8% of the visits to pediatricians. Our detailed results could contribute to evidence-based discussions on health policymaking. PMID:26540064

    Twenty-four hour noninvasive, automatic and ambulatory control of blood pressure (BP) was carried out on 11 normotensive pregnant women in the third trimester of pregnancy with a Del Mar Avionics Model 1978 Pressurometer III System at 7.5 min intervals during 24 h. The patients kept a detailed record of their activities during those 24 h. BP increased from 9 AM to a peak between 7 and 10 PM. Mean (+/- SD) waking and sleeping values were 110.56 +/- 6.68 mm Hg and 96.5 +/- 10.01 mm Hg, respectively, for systolic BP, and 71.41 +/- 5.35 mm Hg and 62.82 +/- 5.47 mm Hg, respectively, for diastolic BP. There was a significant difference in systolic and diastolic BP between sleeping hours and waking hours. We believe that 24-h control of BP behavior in normotensive pregnant women allows us to adequately diagnose hypertensive disease in pregnancy. PMID:2610998

    The purpose of this study was to explore self-identified motivators for regular physical activity among ambulatory nursing home older residents. A qualitative exploratory design was adopted. Purposive sampling was performed to recruit 18 older residents from two nursing homes in Taiwan. The interview transcripts were analyzed by qualitative content analysis. Five motivators of physical activity emerged from the result of analysis: eagerness for returning home, fear of becoming totally dependent, improving mood state, filling empty time, and previously cultivated habit. Research on physical activity from the perspectives of nursing home older residents has been limited. An empirically grounded understanding from this study could provide clues for promoting and supporting lifelong engagement in physical activity among older residents. The motivators reported in this study should be considered when designing physical activity programs. These motivators can be used to encourage, guide, and provide feedback to support older residents in maintaining physical activity. PMID:25054175

    Health behaviors, including physical activity (PA), of registered nurses (RNs) and medical assistants (MAs) are suboptimal but may improve with worksite programs. Using a repeated-measures crossover design, the authors explored if integrating a 6-month worksite non-exercise activity thermogenesis (NEAT) intervention, with and without personalized health coaching via text messaging into workflow could positively affect sedentary time, PA, and body composition of nursing staff without jeopardizing work productivity. Two ambulatory clinics were randomly assigned to an environmental NEAT intervention plus a mobile text message coaching for either the first 3 months (early texting group, n = 27) or the last 3 months (delayed texting group, n = 13), with baseline 3-month and 6-month measurements. Sedentary and PA levels, fat mass, and weight improved for both groups, significantly only for the early text group. Productivity did not decline for either group. This worksite intervention is feasible and may benefit nursing staff. PMID:27143144

    Peritoneal dissemination is a major cause of recurrence in patients with malignant tumors in the peritoneal cavity. Effective anticancer agents and treatment protocols are necessary to improve outcomes in these patients. However, previous studies using mouse models of peritoneal dissemination have not detected any drug effect against peritoneal micrometastasis. Here we used the luciferase assay to evaluate peritoneal micrometastasis in living animals and established an accurate mouse model of early peritoneal microdissemination to evaluate tumorigenesis and drug efficacy. There was a positive correlation between luminescence intensity in in vivo luciferase assay and the extent of tumor dissemination evaluated by ex vivo luciferase assay and mesenteric weight. This model has advantages over previous models because optimal luciferin concentration without cell damage was validated and peritoneal microdissemination could be quantitatively evaluated. Therefore, it is a useful model to validate peritoneal micrometastasis formation and to evaluate drug efficacy without killing mice. PMID:26716425

    Apoptosis has been postulated to play an important role during feline infectious peritonitis virus (FIPV) infection; however, its mechanism is not well characterized. This study is focused on apoptosis and transcriptional profiling of FIPV-infected cells following in vitro infection of CRFK cells with FIPV 79-1146 WSU. Flow cytometry was used to determine mode of cell death in first 42 h post infection (hpi). FIPV infected cells underwent early apoptosis at 9 hpi (p < 0.05) followed by late apoptosis at 12 hpi (p < 0.05) and necrosis from 24 hpi (p < 0.05). Then, next generation sequencing was performed on 9 hpi and control uninfected cells by Illumina analyzer. An aggregate of 4546 genes (2229 down-regulated and 2317 up-regulated) from 17 cellular process, 11 molecular functions and 130 possible biological pathways were affected by FIPV. 131 genes from apoptosis cluster (80 down-regulated and 51 up-regulated) along with increase of apoptosis, p53, p38 MAPK, VEGF and chemokines/cytokines signaling pathways were probably involved in apoptosis process. Six of the de-regulated genes expression (RASSF1, BATF2, MAGEB16, PDCD5, TNFα and TRAF2) and TNFα protein concentration were analyzed by RT-qPCR and ELISA, respectively, at different time-points. Up-regulations of both pro-apoptotic (i.e. PDCD5) and anti-apoptotic (i.e. TRAF2) were detected from first hpi and continuing to deregulate during apoptosis process in the infected cells.

    This study was designed to discriminate, according to their accuracy, between three ambulatory pressurometers (Diasys 200R, Novacor; P IV, Del Mar Avionics; SpaceLab 90202, SpaceLab). The evaluation was performed against invasive arterial reference measurements. Accuracy was assessed by calculating the error on pressure (EOP) as the difference between invasive and non-invasive measurement of arterial blood pressure. For the systolic values, accuracy (mean of EOP differences) and uncertainty (SD of these differences) were -0.9 +/- 9.7, -4.3 +/- 10.1 and -16.7 +/- 10.1 mmHg for, respectively, Diasys, PIV and SpaceLab. For diastolic values, they were, respectively, 5.9 +/- 6.7, 6.8 +/- 8.5 and 9.1 +/- 6.6 mmHg. EOP was then separated in two different types of errors: (i) the error of dispersion appreciated by the index of homogeneity calculated by a Lehmann analysis and leading to a statistical classification (ii) the error due to the drift of EOP with the reference value, this last error being easier to correct. Two different behaviours were observed for the EOP: (i) the drift of EOP of systolic values was significantly larger for the oscillometric (SpaceLab) than for the auscultatory (Diasys and P IV) method, with no difference between Diasys and P IV (ii) the homogeneity index was not statistically different among these three devices. These data suggest that, in case the correction of the drift of EOP is carried out, there is no statistical significant difference in accuracy between these three pressurometers. However, in our experimental conditions, the two ambulatory pressurometers recording the Korotkoff sounds have a better accuracy than the one using the oscillometric approach. PMID:1947731

    The pH of conventional peritoneal dialysis solution is normally in the range of 5.0 to 5.5, because acid has been added during the manufacturing process to prevent caramelization of dextrose during sterilization. We studied the effects of normalizing the pH of conventional peritoneal dialysis solution on superoxide production by normal human neutrophils. At a pH of 6.0, superoxide generation was 4.07 +/- 2.56 (SD) nanomoles per million cells. With normalization of pH to 7.4, superoxide production was 19.3 +/- 7.3 (p less than 0.001). The results suggest that the unphysiologic acidity of conventional peritoneal dialysis solution has deleterious consequences on neutrophil superoxide formation. PMID:2847987

    A study was performed to determine the value of peritoneal lavage in the acute abdomen not related to trauma. Lavage was performed in 33 patients in the evaluation of abdominal pain of sufficient degree to warrant consideration for surgical intervention. Peritoneal lavage was truly positive or truly negative in 64% of the cases. It showed false negative results in 28% and false positive results in 8%. The lavage was most accurate in the evaluation of appendicitis, colonic disease, and intra abdominal bleeding. It was highly inaccurate in the evaluation of cholecystitis and peptic ulcer disease. It was concluded that the peritoneal lavage can be a useful adjunct in the evaluation of patients with abdominal pain and should be considered in difficult diagnostic problems but not routinely employed.

    A case of methyl-malonic acidemia with severe neonatal hyperammoniemia is presented. Treatment during the first days of live with exchange-transfusion, with protein-free blood and peritoneal dialysis induced a decrease of blood ammonia values from 1360 to 270 micrograms/dl and the correction of systemic metabolic acidosis. Continuation of treatment by dietary means was followed by normalization of clinical status and almost total correction of the urinary excretion of methyl-malonic and propionic acids, but the patient died at 33 days of life due to an intercurrent infection. This case, together with a case previously reported of propionic acidemia with neonatal hyperammoniemia and prolonged survival, demonstrates that complementary treatment by means of exchange transfusion and peritoneal dialysis is mandatory in all cases of neonatal hyperammoniemia of metabolic origin, since survival without irreversible neurological damage is possible.

  20. Peritoneal dialysis associated infections: An update on diagnosis and management

    Peritoneal dialysis (PD) is associated with a high risk of infection of the peritoneum, subcutaneous tunnel and catheter exit site. Although quality standards demand an infection rate < 0.67 episodes/patient/year on dialysis, the reported overall rate of PD associated infection is 0.24-1.66 episodes/patient/year. It is estimated that for every 0.5-per-year increase in peritonitis rate, the risk of death increases by 4% and 18% of the episodes resulted in removal of the PD catheter and 3.5% resulted in death. Improved diagnosis, increased awareness of causative agents in addition to other measures will facilitate prompt management of PD associated infection and salvage of PD modality. The aims of this review are to determine the magnitude of the infection problem, identify possible risk factors and provide an update on the diagnosis and management of PD associated infection. Gram-positive cocci such as Staphylococcus epidermidis, other coagulase negative staphylococcoci, and Staphylococcus aureus (S. aureus) are the most frequent aetiological agents of PD-associated peritonitis worldwide. Empiric antibiotic therapy must cover both gram-positive and gram-negative organisms. However, use of systemic vancomycin and ciprofloxacin administration for example, is a simple and efficient first-line protocol antibiotic therapy for PD peritonitis - success rate of 77%. However, for fungal PD peritonitis, it is now standard practice to remove PD catheters in addition to antifungal treatment for a minimum of 3 wk and subsequent transfer to hemodialysis. To prevent PD associated infections, prophylactic antibiotic administration before catheter placement, adequate patient training, exit-site care, and treatment for S. aureus nasal carriage should be employed. Mupirocin treatment can reduce the risk of exit site infection by 46% but it cannot decrease the risk of peritonitis due to all organisms. PMID:24175248
