    Peritoneal calcification, which can lead to intestinal obstruction and potentially lethal hemoperitoneum, is a rare complication of continuous ambulatory peritoneal dialysis. We describe a case in which extensive peritoneal calcification had arisen for this reason. Although the patient was asymptomatic, extensive calcification was present on the parietal and visceral peritoneum, including the hepatic and splenic surface. (author)

    A technique of recording continuous intra-arterial blood pressure in fully ambulatory subjects, on to magnetic tape is described. This method makes use of a specially developed transducer-perfusion unit, which incorporates a strain-gauge pressure transducer and a perfusion system using an electrical "delta" pump. The signal is recorded on cassette tape using a miniature physiological recorder. This recording method has been fully evaluated in the laboratory and has been used clinically on 550 occasions with satisfactory results. Technical limitations and clinical experience of this recording technique are discussed.

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

    Full Text Available Patients with end-stage renal disease (ESRD continue to increase in number worldwide, especially in developing countries. Although continuous ambulatory peritoneal dialysis (CAPD has comparable survival advantages as hemodialysis (HD, it is greatly underutilized in many regions worldwide. The prevalence of use of CAPD in Egypt is 0.29/million population in 2017. The aim of this study is to describe the current state and practice of CAPD in Egypt and included 22 adult patients who were treated by CAPD. All the study patients were switched to CAPD after treatment with HD failed due to vascular access problems. Patients were mainly female (68.2 % with the mean age of 49.77 ± 11.41 years. The average duration on CAPD was 1.76 ± 1.30 years. Hypertension was the main cause of end-stage renal disease (ESRD constituting 36.4%, followed by diabetes (27.3 %, and toxic nephropathy (4.5%. Of importance is that about 31.8% of patients had ESRD of unknown etiology. The mean weekly Kt/V urea of patients on PD was 1.92 ± 0.18. The mean hemoglobin, serum calcium, phosphorus, parathormone, and albumin levels were 10.27 ± 1.98 g/dL, 8.36 ± 1.19 mg/dL, 5.70 ± 1.35 mg/dL, 541.18 ± 230.12 pg/mL, and 2.98 ± 0.73 g/dL, respectively. There was no significant difference between diabetic and nondiabetic CAPD patients regarding demographic and laboratory data. Our data indicate that there is continuing underutilization of CAPD in Egypt which may be related to nonavailability of CAPD fluid, patient factors (education and motivation, gradual decline of the efficiency of health-care professionals, and lack of a national program to start PD as the first modality for renal replacement therapy. It is advised to start an organized program to make CAPD widespread and encourage local production of PD fluids to reduce the cost of CAPD.

    to determine the cost of institutional and familial care for patients with chronic kidney disease replacement therapy with continuous ambulatory peritoneal dialysis. a study of the cost of care for patients with chronic kidney disease treated with continuous ambulatory peritoneal dialysis was undertaken. The sample size (151) was calculated with the formula of the averages for an infinite population. The institutional cost included the cost of outpatient consultation, emergencies, hospitalization, ambulance, pharmacy, medication, laboratory, x-rays and application of erythropoietin. The family cost included transportation cost for services, cost of food during care, as well as the cost of medication and treatment materials acquired by the family for home care. The analysis included averages, percentages and confidence intervals. the average annual institutional cost is US$ 11,004.3. The average annual family cost is US$ 2,831.04. The average annual cost of patient care in continuous ambulatory peritoneal dialysis including institutional and family cost is US$ 13,835.35. the cost of chronic kidney disease requires a large amount of economic resources, and is becoming a serious problem for health services and families. It's also true that the form of patient management in continuous ambulatory peritoneal dialysis is the most efficient in the use of institutional resources and family.

  19. Maintenance of continuous ambulatory peritoneal dialysis in elderly patients.

    2012-01-01

    In Japan, peritoneal dialysis (PD) remains the principal modality of home dialysis for the elderly although PD patients accounted for only 3.3% (n = 9,728) of the overall dialysis patient population. One of the preventing factors for introduction of PD in elderly patients is the Japanese public nursing care system. Besides, difficulties in the continuation of dialysis therapy will arise because of the progression of dementia as well as the decline in muscular strength, vigor, and physical strength of patients. In spite of these difficulties, some local dialysis centers tried to maintain and manage elderly dialysis patients at home by utilizing diverse social resources, in addition to obtaining the cooperation of care givers such as family members. In our hospital, approximately 40% of patients who started dialysis therapy have selected PD. To support patients on PD, several special forms of care are prepared: utilization of visiting nurse care or home-visit nursing care services, supply of information on renal failure and education to home-care support providers and welfare service facility staff members. In addition, modulation of PD therapy such as automated PD and hemodialysis and PD in combination is also properly prepared. Lastly, the organization of a team, including physicians, nurses, social workers and dietitians, and the construction of a centralized patient information management system are important for elderly patients who need dialysis therapy.

    2010-07-01

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

    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.

    2014-05-01

    A retrospective study involving 65 non-ambulatory patients with hypotonic neuromuscular scoliosis has assessed the effectiveness of a sacral rod/bone onlay technique for extending spinal fusion to the sacrum. To extend posterior spinal fusion to the sacrum, we used either 1 Harrington rod and 1 Luque L rod with sublaminar wires in 14 patients (Group 1) or two rods with sublaminar wires in 51 patients (Group 2) along with abundant autograft and allograft bone covering the ends of the rods. Diagnoses were Duchenne muscular dystrophy 53, spinal muscular atrophy 4, myopathy 3, limb girdle muscular dystrophy 2, infantile FSH muscular dystrophy 1, cerebral palsy 1, and Friedreich ataxia 1. Mean age at surgery was 14.3 years (±2.2, range 10.9-25.2). Radiographic follow-up (2 years post-surgery or greater) was 6.4 years (±4.4, range 2-25.3). Using the onlay technique, all patients fused with no rod breakage or pseudarthrosis. For the entire series, the mean pre-operative scoliosis was 54.7° (±31.1, range 0°-120°) with post-operative correction to 21.8° (±21.7, range 0°-91°) and long-term follow-up 24° (±22.9, range 0°-94°). For pelvic obliquity, pre-operative deformity was 17.3° (±11.3, range 0°-51°) with post-operative correction to 8.9° (±7.8, range 0°-35°) and long-term follow-up 10.1° (±8.1, range 0°-27°). Five required revision at a mean of 3.3 years post-original surgery involving rod shortening at the distal end. One of these had associated infection. Lumbosacral stability and long-term sitting comfort have been achieved in all patients. Problems can be minimized by positioning the rods firmly against the sacrum at the time of surgery with a relatively short extension beyond the L5-S1 junction. The procedure is valuable in hypotonic non-ambulatory neuromuscular patients whose immobility enhances the success rate for fusion due to diminished stress at the lumbosacral junction. It is particularly warranted for those with osteoporosis and

  7. Relationship Between Continuity of Ambulatory Care and Risk of Emergency Department Episodes Among Older Adults.

    Nyweide, David J; Bynum, Julie P W

    2017-04-01

    We determine whether visit patterns indicative of higher continuity are related to a lower risk of presenting at the emergency department (ED) among older adults. This study was a survival analysis between 2011 and 2013 of a 20% random sample of fee-for-service Medicare beneficiaries aged 66 years or older. Ambulatory visit patterns were measured starting in 2011 for up to 24 months using 2 continuity metrics measured on a 0 to 1 scale-Continuity of Care (COC) score and the Usual Provider Continuity (UPC) score. The composite outcome of an ED episode was defined as occurrence of an ED visit with discharge home, an observation stay, or hospital admission. Time-dependent Cox proportional hazards regression models controlled for patient demographic characteristics, comorbidities, previous use, and regional factors, with censoring for death or occurrence of the composite outcome. In a secondary analysis, continuity was measured in the 12 months preceding an ED episode to test whether it was associated with type of ED episode. The relative rate of ED episodes decreased approximately 1% for every 0.1-point increase in the COC score (adjusted hazard ratio 0.99; 95% confidence interval 0.99 to 0.99; Pcontinuity was associated with a 1% lower risk of observation stay but a 3% to 4% higher risk of hospital admission relative to an ED visit with discharge home. Ambulatory visit patterns exhibiting more continuity were associated with a lower rate of ED utilization for older adults with fee-for-service Medicare coverage. The association of higher continuity with lower risk of ED use but differences in outcome when an ED visit does occur may reflect more appropriate referral to the ED when outpatient management is no longer adequate.

    1993-01-01

    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 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.

    Bone metabolism inpatients with chronic renal failure treated by continuous ambulatory peritoneal dialysis (CAPD) was evaluated. IRMA, RRA and RIA were used to detect PTH, 25 (OH)D 3 , 1,25(OH) 2 D 3 , BGP, Ca and P levels in the blood of 24 CAPD patients. PTH and BGP were increased in uremic patients ad decreased after CAPD. 25(OH)D 3 and 1,25 (OH) 2 D 3 were decreased in the patients, but their levels were not changed further after CAPD. PTH had negative correlation with 25 (OH)D 3 (r = -0.379, P 2 D 3 (r = -0.451, P < 0.01). PTH had positive correlation with BGP (r 0.501, P < 0.01) in CAPD patients, and the correlativity was decreased by CAPD. The results showed: PTH hypersecretion is a main factor inducing bone metabolism disturbance, and bone turnover rate is decreased in these patients by CAPD

    Full Text Available 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.

    There is currently no reliable treatment for phantom limb pain (PLP). Chronic PLP and associated cortical abnormalities may be maintained from abnormal peripheral input, raising the possibility that a continuous peripheral nerve block (CPNB) of extended duration may permanently reorganize cortical pain mapping, thus providing lasting relief. Three men with below-the-knee (2) or -elbow (1) amputations and intractable PLP received femoral/sciatic or infraclavicular perineural catheter(s), respectively. Subjects were randomized in a double-masked fashion to receive perineural ropivacaine (0.5%) or normal saline for over 6 days as outpatients using portable electronic infusion pumps. Four months later, subjects returned for repeated perineural catheter insertion and received an ambulatory infusion with the alternate solution ("crossover"). Subjects were followed for up to 1 year. By chance, all three subjects received saline during their initial infusion and reported little change in their PLP. One subject did not receive crossover treatment, but the remaining two subjects reported complete resolution of their PLP during and immediately following treatment with ropivacaine. One subject experienced no PLP recurrence through the 52-week follow-up period and the other reported mild PLP occurring once each week of just a small fraction of his original pain (pretreatment: continuous PLP rated 10/10; posttreatment: no PLP at baseline with average of one PLP episode each week rated 2/10) for 12 weeks (lost to follow-up thereafter). A prolonged ambulatory CPNB may be a reliable treatment for intractable PLP. The results of this pilot study suggest that a large, randomized clinical trial is warranted. Wiley Periodicals, Inc.

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

    Heart failure is one of the most cost-intensive chronic diseases and the most common cause of hospitalization. More than 60% of the treatment costs of heart failure are incurred in the inpatient sector in Germany. However, hospital admissions due to heart failure are considered to be potentially avoidable through effective and continuous ambulatory care. Our aim is to examine whether continuity in ambulatory care is associated with hospitalizations due to heart failure. Using insurance claims data from Germany's biggest statutory health insurance company, we defined three measures of continuity of care: Continuity of Care Index (COCI), Usual Provider Index (UPC) and the Sequential Continuity Index (SECON). We analyzed whether these measures are associated with hospitalization due to heart failure using separate logistic regression models. We controlled for a wide range of covariates such as sex, age and the Charlson comorbidity index. Data of 382 118 heart failure patients were included in the analyses. Index values range from 0.77 to 0.89. Results of logistic regression analyses indicate that the continuity indices COCI, UPC and SECON based on visits to general practitioners (GPs), cardiologists and internists are negatively associated with the probability of hospitalization whereas of the continuity indices based on GP visits only SECON is significantly associated with hospitalization. The results indicate that the overall continuity in the ambulatory sector is high for heart failure patients in Germany. Public policy should, nevertheless, focus on increasing sequential continuity of specialist and generalist ambulatory care as this was found to be significantly associated with a reduced likelihood of hospitalization. © The Author 2016.

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

    We aimed to assess whether there is a significant relation between periodontal health status and inflammation in uremic patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and also to reveal the efficiency of periodontal treatment in patients with various degrees of periodontal problems. Overall, 68 patients undergoing CAPD were included in the study. Clinical indices and measurements were obtained at baseline and panoramic radiographies were used for the diagnosis. According to the baseline values, patients were stratified into four groups according to the severity of periodontal problems as follows: healthy/gingivitis, slight-to-moderate, and severe periodontitis. A control examination was performed 3 months after the periodontal treatment for only 43 patients. Clinical and laboratory parameters before and after treatment were compared. The frequency of periodontal disease was found to be high in uremic patients on CAPD. The frequency and severity of periodontitis was also found to be significantly (p periodontitis rate was found to be higher in patients with cardiovascular disease (p diabetes mellitus (p periodontal examination should be a routine part of management of the uremic patients on CAPD because periodontal disease could be one of the hidden sources of unexplained inflammatory status.

    Experience in the use of continuous ambulatory peritoneal dialysis (CAPD) for the treatment of end stage renal failure in Nottingham was reviewed. During six years 150 patients aged from 11 to 73 received this type of treatment. At three years patient actuarial survival was 69% and CAPD technique survival was 41%. Although CAPD was satisfactory as a first treatment for many patients, its long term use was possible in only a few. Actuarial survival of patients who changed to haemodialysis was 64% at one year after the change, suggesting that unsuccessful CAPD increased the risk of death. Hospital haemodialysis was the only suitable form of treatment for most patients in whom CAPD had been abandoned. British renal units have adopted CAPD to a much greater extent than those in Europe, but care in the selection of patients is necessary to reduce mortality, and many patients may eventually need hospital haemodialysis. Greater numbers of hospital haemodialysis places will probably have to be made available to meet this extra demand.

    Despite several modifications of the continuous ambulatory peritoneal dialysis (CAPD) technique over the last decade, peritonitis remains a major source of morbidity and is the leading cause of dropout for patients maintained on CAPD therapy. Recently, Baxter Healthcare introduced the Ultra Twin bag system, which uses drainage and infusion bags both secured to Y connecting tubing. Previous nonrandomized studies comparing the Ultra Twin bag system with other systems have indicated an improvement in the peritonitis rate with the Ultra Twin bag system. In this study, 82 patients were randomized to use the Ultra Twin bag system or the Ultra Y-set system, which uses only the drainage bag already attached to the Y connecting tubing. Peritonitis rates were significantly lower with the Ultra Twin bag system, one episode per 33.9 patient months, compared with the Ultra Y-set system, one episode per 11.7 patient months (P < 0.05). Furthermore, the 1-yr infection-free survival rates with the Ultra Twin bag system and the Ultra Y-set system were 71 and 40%, respectively. Exit-site infections were lower with the Ultra Twin bag system, one episode per 12.5 patient months, compared with the Ultra Y-set system, one episode per 28.3 patient months, although this difference was not statistically significant (P = 0.084). The effect of the reduction in the infection rate on patient dropout with the Ultra Twin bag system remains to be addressed.

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

    ♦ Background: Residual renal function (RRF) is an important prognostic indicator in continuous ambulatory peritoneal dialysis (CAPD) patients. We determined the predictors of RRF loss in a cohort of incident CAPD patients. ♦ Methods: We reviewed the record of 645 incident CAPD patients. RRF loss is represented by the slope of decline of residual glomerular filtration rate (GFR) as well as the time to anuria. ♦ Results: The average rate of residual GFR decline was -0.083 ± 0.094 mL/min/month. The rate of residual GFR decline was faster with a higher proteinuria (r = -0.506, p peritonitis episodes were independent predictors of progression to anuria, while a higher baseline GFR was protective. Each 1 g/day of proteinuria is associated with a 13.2% increase in the risk of progressing to anuria, each 10 g/day higher glucose exposure is associated with a 2.5% increase in risk, while each peritonitis episode confers a 3.8% increase in risk. ♦ Conclusions: Our study shows that factors predicting the loss of residual solute clearance and urine output are different. Proteinuria, baseline residual GFR, and the use of diuretics are independently related to the rate of RRF decline in CAPD patients, while proteinuria, glucose exposure, and the number of peritonitis episodes are independent predictors for the development of anuria. The role of anti-proteinuric therapy and measures to prevent peritonitis episodes in the preservation of RRF should be tested in future studies. PMID:24497594

    ♦ Fructo-oligosaccharides (FOS) exhibit soluble-fiber properties that beneficially affect bowel function and relieve constipation. The effects of FOS supplementation on constipation and biochemical parameters were examined in elderly continuous ambulatory peritoneal dialysis (CAPD) patients. ♦ This randomized, double-blind, placebo-controlled, cross-over study was performed in elderly CAPD patients (5 males and 4 females) with chronic constipation. All subjects were randomly assigned to receive either 20 g FOS or placebo daily for 30 days. After a 14-day washout period, the patients were switched to the other substance for 1 more month. Before and after each treatment period, frequency of defecation, characteristics of feces, and colonic transit were evaluated. Biochemical parameters were also assessed. ♦ Fructo-oligosaccharides significantly increased the frequency of defecation (10.5 ± 2.0 vs 6.2 ± 1.4 times per week, p constipation. Further studies are needed to better assess the biochemical effects of FOS in the chronic kidney disease population. Copyright © 2016 International Society for Peritoneal Dialysis.

    We studied lymphocyte subset counts in comparison with normal subjects in order to clarify the abnormalities of cellular immune responses in uremic patients undergoing continuous ambulatory peritoneal dialysis (CAPD). The study included 37 CAPD patients and 45 normal individuals, as the control group. For the study, CAPD patients were divided into four groups depending on duration of replacement therapy. Group I consisted of patients treated for 0-6 months (n=6), group II for 6-12 months (n=6), group III for 13-24 months (n=16), and group IV for more than 25 months (n=9). Flow cytometry was used for estimation of lymphocyte subsets (determination of CD2, CD3, CD3+/CD4+, CD3+/CD8+, CD3-/16+56+, CD19, CD4/CD8). Our patients started CAPD with decreased lymphocyte subset counts, slightly above the normal range (excluding CD3 -/16+56+, CD2). After 6 months of CAPD therapy, an increase in CD4/CD8 ratio was observed and all examined lymphocyte subset counts decreased (excluding CD2). In patients on CAPD for more than 25 months, CD3+/CD4+, CD19 counts were below the normal range, CD3 -/16+56+ exceeded the upper limit of normal range and at the same time mean total lymphocyte count (TLC) was maintained in the normal range. We recommend lymphocyte subset determinations for detection of immune abnormalities in the course of CAPD treatment.

    Full Text Available Solute clearance measurement is an objective means of quantifying the dose of peritoneal dialysis (PD. Despite continued debate on the interpretation and precise prognostic value of small solute clearance in PD patients, guidelines based on solute clearance values are common in clinical practice. There is limited information on the solute clearance indices and PD adequacy parameters among this predominantly low socioeconomic status PD population. We investigated the solute clearance among continuous ambulatory peritoneal dialysis (CAPD patients at the Charlotte Maxeke Johannesburg Academic Hospital and its relationship with other parameters of PD adequacy. Seventy patients on CAPD were studied in this cross-sectional study. Solute clearance was assessed using urea clearance (Kt/V. Linear regression analysis was used to determine factors associated with solute clearance, while analysis of variance was used to test the influence of weekly Kt/V on blood pressure (BP, hemoglobin (Hb and other biochemical parameters. The mean age of the study population was 37.9 ± 12.4 years, 43% were females and 86% were black Africans. The mean duration on CAPD was 19.7 ± 20.8 months. Mean systolic and diastolic BP were 144 ± 28 and 92 ± 17 mm Hg, respectively. The mean Hb was 11.1 ± 2.2 g/dL and the mean weekly Kt/V was 1.7 ± 0.3. Factors like systolic BP, Hb level, serum levels of cholesterol, calcium, phosphate, parathyroid hormone and albumin were not significantly associated with the weekly Kt/V. We conclude that the dose of PD received by the majority of our patients in terms of the weekly Kt/V is within the recommended values and that this finding is significant considering the low socioeconomic background of our patients. There is no significant association between Kt/V and other indices of dialysis adequacy.

    Full Text Available Peritonitis is one of the most common and important complications in patients on continuous ambulatory peritoneal dialysis (CAPD. Fungal peritonitis isreported in 4-8% of peritonitis episodes. Fungal peritonitis due to Paecilomyces species is not common. We report a case of CAPD peritonitis due to P. varioti. We immediately removed the CAPD catheter and IV amphotericin was administered for 4 weeks along with temporary hemodialytic support followed by successful catheter reinsertion.

    This study's objective was to determine whether offering dietary advice was effective in supporting patients in adjusting energy intake. We performed a prospective, randomized, controlled trial of dietary intervention involving 59 patients on continuous ambulatory peritoneal dialysis over a 4-month follow-up period. The study involved outpatients on home-based renal replacement therapy. All participants were adult patients on continuous ambulatory peritoneal dialysis. All eligible patients were invited to take part. Subjects were randomized into two groups: control and intervention. Those with diabetes mellitus, malabsorption, malignancy, or eating disorders were excluded. Baseline measurements to assess current dietary intake and nutritional status were performed in all subjects. Measurements included a 5-day food diary, subjective global assessment (SGA), anthropometry, and serum biochemistry. After analysis of the food diaries, the participants in the control group were given follow-up dietary advice that would enable them to match intake with current dietary recommendations for this group of 1.2 g of protein per kilogram of ideal body weight, 25 cal/kg ideal body weight. Participants in the intervention group were given follow-up dietary advice that would encourage them to match energy intake with an estimate of total energy expenditure based on their calculated basal metabolic rate and physical activity level as designated using information from SGA, with a significantly lower protein intake of 0.8 to 1.0 g/kg ideal body weight and an emphasis on calories from carbohydrate and fat. Both groups completed further 5-day food diaries at 2 and 4 months to assess their ability to make the recommended changes. SGA, anthropometry, and biochemistry were all remeasured at the end of the study period. Differences in energy and protein intakes between and within the two groups from baseline to 4 months were assessed. Protein and energy intakes did not change during 4

    The aging population has significant implications for the community. The increasing number of elderly end-stage renal disease (ESRD) patients presses the renal team to find an appropriate management plan. We used a retrospective analysis to study the effectiveness of continuous ambulatory peritoneal dialysis (CAPD) in elderly ESRD patients. Of the 328 CAPD patients recruited for the study, 121 were in the elderly group (>or=65 years of age), and 207 were in the control group (under 65 years of age). Median age in the elderly group was 71 years, and in the control group, 51 years. The elderly group had a higher prevalence (54.5%) of diabetes mellitus. The 2-year and 5-year rates of patient survival were 89.3% and 54.8% respectively in the elderly group and 92.2% and 62.9% in the control group (p=0.19). The 2-year and 5-year rates of technique survival were 84.0% and 45.7% respectively in the elderly group and 80.9% and 49.1% in the control group (p=0.75). The probability of a 12-month peritonitis-free period was 76.6% in the elderly group and 76.5% in the control group (p=0.75). One hundred elderly patients (82.6% of the group) performed their CAPD exchanges by themselves. We observed no significant difference in clinical outcome-including patient survival, technique survival, and peritonitis-free period-between the elderly self-care CAPD and the elderly assisted CAPD groups. In elderly ESRD patients, CAPD is an effective dialysis modality. A slightly longer training time is to be expected for elderly patients. Self-care CAPD for elderly patients who are capable of performing their own exchanges provides them with an independent home life.

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

    This is a multi-centre study to determine cost efficiency and cost effectiveness of the Ministry of Health centre haemodialysis and continuous ambulatory peritoneal dialysis (CAPD) programme. Forty-four haemodialysis and 11 CAPD centres were enrolled in this study in 2001. Sixty patients, 30 from each modality, were evaluated. Micro-costing was used to determine costs. The number of haemodialyses conducted ranged from 402 to 23,000 procedures per year, while for CAPD, output ranged from 70 to 2300 patient months/year. Cost ranged from RM79.61 to RM475.79 per haemodialysis treatment, with a mean cost of RM169 per HD (USD 1 = RM 3.80). The cost of CAPD treatment ranged from RM1400 to RM3200 per patient month, with a mean of RM2186. Both modalities incurred similar outpatient costs. The cost of erythropoeitin per year is RM4500 and RM2500 for haemodialysis and CAPD, respectively. The number of life years saved is 10.96 years for haemodialysis and 5.21 years for CAPD. Cost per life year saved is RM33 642 for haemodialysis and RM31 635 for CAPD. The cost for land, building, equipment, overheads, and staff were higher for haemodialysis, while consumables and hospitalization cost more for CAPD. Sensitivity analysis was performed for two discount rates (3 and 5%), varying erythropoietin doses and maximum and minimum overheads. Relative cost effectiveness of haemodialysis and CAPD was unchanged in all sensitivity scenarios, except for overhead costs, which influenced the cost effectiveness of HD. It is economically viable to promote the use of both CAPD and haemodialysis because the cost effectiveness of both are nearly equal.

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

    Full Text Available Endothelial dysfunction is associated with diabetic micro- and macroangiopathy as well as with the decline in creatinine clearance. It has been suggested that endothelial dysfunction presents in patients (pts on continuous ambulatory peritoneal dialysis (CAPD. The objective of this study was to examine the plasma biomarkers of endothelial dysfunction and their association with IMT of carotid arteries in diabetic and non-diabetic patients on CAPD. This study included 37 CAPD pts (25 with type II diabetes and 12 non-diabetic pts mean age 59.2 years ± 2.48. Plasma von Willebrand factor (vWF activity, serum albumin, glucose, total cholesterol, triglycerides and lipoprotein (a levels, as well as serum level of homocysteine, parathyroid hormone (PTH in plasma and microalbuminuria was determined. Ultrasound examination of carotid arteries was performed in all patients by measured bilateral intima-media thickness of carotid artery (CIMT. Mean IMT value was significantly higher in type 2 DM patients (0.86 ± 0.04 mm compared to non-diabetic patients (0.52 ± 0.06 mm on peritoneal dialysis (p<0.0001. There was also a significant difference in lipids/triglycerides and Lp (a/, procoagulation (fibrinogen, von Wilebrand factor, factor VIII and inflammatory markers (CRP level between type 2 DM and non-diabetic CAPD patients. A stepwise multiple regression analysis revealed that log triglycerides and factor VIII were independent factors for the IMT. The results of this research impose that diabetic type 2 CAPD patients have developed systemic alteration of endothelial function and higher risk of cardiovascular complications compared to non-diabetic CAPD patients.

    Full Text Available Objectives: The objective of the study was to assess the mechanical and nonmechanical complications in patients with end-stage renal disease (ESRD undergoing continuous ambulatory peritoneal dialysis (CAPD and to access the contributing factors to improve the patient's survival and reduce morbidity and mortality. Materials and Methods: This observational study was carried out on 121 patients with ESRD undergoing CAPD at the Nephrology Unit of SKIMS, Srinagar, Jammu and Kashmir, India. We retrospectively reviewed the medical records of 121 CAPD patients, in which a double-cuffed straight Tenckhoff catheter was inserted using surgical technique from July 2012 to July 2016. Results: The mean age of the study patients was 45 ± 11.5 years. Males outnumbered female, with a ratio of 1.42:1. The most common etiology for ESRD was diabetes mellitus (38.84%, followed by hypertension (30.57% and chronic glomerulonephritis (18.18%. About three-fourth of the study patients (77.19% were on CAPD therapy for more than 6 months showing better acceptability of CAPD therapy. Peritonitis was the most common nonmechanical complication and was seen in 45.45% patients. 14.04% patients had recurrent episodes of peritonitis. Catheter-related complications are early encountered and are mostly due to faulty technique. Conclusion: The complications associated with CAPD are diverse and most of the mechanical complications are catheter related and often result from errors made during catheter implantation. Furthermore, the presence of comorbid factors plays a provital role in exacerbating these complications. Proper evaluation of the patient, care during catheter insertion, and postoperative period can markedly reduce most of these complications and reduce mortality and morbidity associated with CAPD.

The prevalence of chronic kidney disease has been predicted to grow the fastest in low- to middle-income countries (LMICs. There is evidence that people living in LMICs have the highest need for renal replacement therapy (RRT despite the lowest access to various modalities of treatment. As continuous ambulatory peritoneal dialysis (CAPD does not require advanced technologies, much infrastructure, or need for dialysis staff support, it should be an ideal form of RRT in LMICs, particularly for those living in remote areas. However, CAPD is scarcely available in many LMICs, and even where available, there are several hurdles to be confronted regarding patient selection for this modality. High cost of CAPD due to unavailability of fluids, low patient education and motivation, low remuneration for nephrologists, lack of expertise/experience for catheter insertion and management of complications, presence of associated comorbid diseases, and various socio-demographic factors contribute significantly toward reduced patient selection for CAPD. Cost of CAPD fluids seems to be a major constraint given that many countries do not have the capacity to manufacture fluids but instead rely heavily on fluids imported from developed countries. There is need to invest in fluid manufacturing (either nationally or

Meanwhile, increased pulse wave velocity (PWV, the marker of arterial stiffness, has been proved to be an independent predictor of cardiovascular disease. The relationship between serum albumin and PWV in continuous ambulatory peritoneal dialysis patients (CAPD was studied.Methods: Sixty-two CAPD patients were studied. The average age was 63 ± 12 years and dialysis duration was 23 ± 22 months. Serum albumin, C-reactive protein (CRP, and carotid-femoral PWV were measured.Results: Among these patients, 43.5% were men. The mean serum albumin concentration was 37 ± 4 g/L and PWV was 11.9 ± 2.3 m/s. PWV positively correlated with age (r = 0.35, P < 0.01, diabetes (yes = 1, no = 0; r = 0.292, P < 0.05, systolic blood pressure (SBP; r = 0.493, P < 0.001 and CRP (r = 0.295, P < 0.05, but negatively correlated with serum albumin (r = −0.357, P < 0.01.

    2017-01-01

    Background Ambulatory electrocardiography (ECG) monitors are often used to detect cardiac arrhythmia. For patients with symptoms, an external cardiac loop recorder will often be recommended. The improved recording capacity of newer Holter monitors and similar devices, collectively known as longterm continuous ambulatory ECG monitors, suggests that they will perform just as well as, or better than, external loop recorders. This health technology assessment aimed to evaluate the effectiveness, cost-effectiveness, and budget impact of longterm continuous ECG monitors compared with external loop recorders in detecting symptoms of cardiac arrhythmia. Methods Based on our systematic search for studies published up to January 15, 2016, we did not identify any studies directly comparing the clinical effectiveness of longterm continuous ECG monitors and external loop recorders. Therefore, we conducted an indirect comparison, using a 24-hour Holter monitor as a common comparator. We used a meta-regression model to control for bias due to variation in device-wearing time and baseline syncope rate across studies. We conducted a similar systematic search for cost-utility and cost-effectiveness studies comparing the two types of devices; none were found. Finally, we used historical claims data (2006–2014) to estimate the future 5-year budget impact in Ontario, Canada, of continued public funding for both types of longterm ambulatory ECG monitors. Results Our clinical literature search yielded 7,815 non-duplicate citations, of which 12 cohort studies were eligible for indirect comparison. Seven studies assessed the effectiveness of longterm continuous monitors and five assessed external loop recorders. Both types of devices were more effective than a 24-hour Holter monitor, and we found no substantial difference between them in their ability to detect symptoms (risk difference 0.01; 95% confidence interval −0.18, 0.20). Using GRADE for network meta-analysis, we evaluated the

    We herein present the first reported case of severe proptosis caused by ocular and periocular hemorrhages in a continuous ambulatory peritoneal dilaysis patient without previous history of trauma. The bleeding tendency caused by uremia and the use of warfarin during uncontrolled high blood pressure were most likely responsible for her ocular and periocular hemorrhages. Appropriate control of blood pressure and adequate self-care education are important for the prevention and treatment of any bleeding complications in uremic patients receiving both maintenance anticoagulation therapy and peritoneal dialysis.

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

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

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

    Full Text Available A 72-year-old man undergoing continuous ambulatory peritoneal dialysis (CAPD for chronic renal failure and who had undergone right upper lobectomy for lung adenocarcinoma (pT2aN0M0 2 years ago was admitted for recurrence of lung cancer presenting as multiple brain metastases. An epidermal growth factor receptor mutation analysis of his lung cancer revealed a deletion of 15 nucleotides (E746-A750 in exon 19. After whole-brain radiotherapy, we started daily administration of 250 mg gefitinib under the continuation of CAPD and performed a pharmacokinetic analysis. We speculated that the plasma concentration of gefitinib reached the steady state at least by day 16 after the start of gefitinib (626.6 ng/ml at trough level. On day 46, the plasma concentration was 538.4 ng/ml at trough level and the concentration in the peritoneal dialysis fluid was 34.6 ng/ml, suggesting that CAPD appeared to have little effect on the pharmacokinetics of gefitinib. During gefitinib therapy, there were no significant adverse events except for grade 2 diarrhea. Gefitinib could be safely administered to a patient undergoing CAPD.

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

    This article describes our five-year experience of continuous ambulatory peritoneal dialysis (CAPD) with bag exchanges performed without use of a face mask. The study took place in the renal unit at a university hospital. All patients admitted to the CAPD program from February 1995 to March 2000 were trained to perform bag exchanges without use of a face mask. Occurrence of peritonitis episodes was the outcome of interest. We evaluated 94 patients (52 women, 42 men) with a mean age of 48 +/- 21 years and a total follow-up of 50,502 patient-days. During that time, 79 episodes of peritonitis occurred in 46 patients, for a peritonitis rate of 0.57 episodes/year. The most frequently isolated micro-organisms were Staphylococcus epidermidis in 20 patients (25.3%) and S. aureus in 11 patients (13.9%). Renal transplantation was the major cause of drop-out [23 patients (43.4%)], followed by peritonitis [14 patients (26.4%)], death due to cardiovascular complications [9 patients (17.0%)], loss of ultrafiltration [2 patients (3.8%)], and other causes [5 patients (9.4%)]. The probability of being free of peritonitis at 12 months was 0.60, and at 60 months, 0.37. Peritonitis rates during the study period were not different from those reported by other centers, supporting the hypothesis that routine use of a face mask during CAPD bag exchange may be unnecessary.

    Full Text Available Peritoneal dialysis is an established form of renal replacement therapy used in many patients with end-stage renal disease. The key to a successful chronic peritoneal dialysis is a permanent and safe access to the peritoneal cavity. This study was conducted in order to evaluate the catheter survival and its related factors in Imam Khomeini Hospital. A total of 80 catheters were inserted into 69 patients (52 men and 28 women with end-stage chronic renal failure during a period of 84 months. Retrospectively the correlation between catheter survival (overall and event free with demographic factors (sex and age, surgical factors (surgeons and surgical methods, nephrologic factors (the causes of peritoneal dialysis selection and the history of hemodialysis and peritonitis factors (the history and number of peritonitis has been evaluated. The mean age of the patients was 48.35 years (16 to 79 years. The overall survival of catheters or the probability of having a functioning catheter after one, two and three years was 53%, 41%, 22%, respectively. The event free survival of the catheter or the probability of having a functioning catheter without any problems after one year was 14%. It has been found out that among all factors in this study only history of hemodialysis had statistically significant effect on the overall survival of continuous ambulatory peritoneal dialysis catheter (P = 0.04. It seems that the overall survival of catheters is better when CAPD is started before any other attempts for hemodialysis.

    To investigate the abnormalities of cellular immune responses in patients on hemodialysis (HD) and in those on continuous ambulatory peritoneal dialysis (CAPD). Forty-five (45) healthy volunteers, 34 patients on HD therapy, and 37 patients on CAPD were recruited for the present study. Lymphocyte subpopulations (CD2+, CD3+, CD3+/CD4+, CD3+/CD8+, CD3-/16+56+, CD19, and CD4/CD8) were determined by flow cytometry. Lymphopenia, decreased absolute counts, and altered percentage values of CD3+, CD3+/ 4+, and CD19+ subpopulations were found in both patient groups. The HD and CAPD patients showed increased percentages of natural killer cells (CD3-/16+56+) compared to controls but CD4+/CD8+ ratio showed no significant changes among uremic patients and controls. Replacement therapy may contribute to the quantitative alterations of immune subsets found in HD and CAPD patients compared to normal subjects. We speculate that these changes account, at least in part, for the immune dysregulation observed in patients with chronic renal failure. Analysis of lymphocyte subsets will help the research and the evaluation of the possible causes of immunodeficiency in uremic patients undergoing replacement therapy and will probably contribute to more efficient and preventive strategies.

    The authors' experience in managing 17 diabetic patients among their first 100 consecutive patients treated with continuous ambulatory peritoneal dialysis (CAPD) was reviewed. The diabetics were significantly older than the non-diabetics, but their biochemistry was comparable to that of the non-diabetics. With three exchanges a day, the requirement for antihypertensives was high (60%). Exit-site infection occurred at a rate of one episode per 9.7 patient-months, and the frequency of peritonitis averaged one episode per 9.4 patient-months; the main culprit was Staphylococcus pyogenes. Rehabilitation was good because the patients had to finance their treatment. In spite of old age, 23% worked full-time. There was no progressive increase in serum cholesterol or triglycerides. Glycemic control was good and was comparable whether the patients were given insulin subcutaneously or intraperitoneally. There was a highly significant (p less than 0.001) positive correlation between fasting blood glucose levels and HbA1 concentrations. Fasting blood glucose concentrations did not correlate with either serum cholesterol or triglyceride concentrations. Diabetic retinopathy progressed in five patients, to the point that their vision was severely impaired. There was no relationship between the degree of glycemic control and progression of diabetic retinopathy. Two patients died of cardiovascular causes, but there were no peritonitis-related deaths. Cummulative patient survival at 2 years was 86%, and the corresponding technique survival, 100%.

    Peritoneal protein loss is one of the inevitable consequences during continuous ambulatory peritoneal dialysis (CAPD). Our objective was to study the effect of sulodexide on the protein loss and efficiency of dialysis. This study included six patients receiving CAPD treated with sulodexide at the dose of 600 IU/day given by intraperitoneal injection for 10 days. Clinical and biologic parameters were assessed before starting the treatment (D0 and after 10 days of treatment (D10. We also evaluated the benefit of therapy persisting 20 days after the end of treatment (D30. The sulodexide administration produced a significant improvement of the peritoneal function as determined by a significant increase in the following ratios measured at the 4 th h of dwell time on D0 and D30: dialysate-to plasma (D/P) creatinine from 0.63 ± 1.45 to 0.85 ± 0.073 (P = 0.028) and D/P urea from 0.63 ± 0.15 to 79 ± 0.2 (P = 0.048). A significant decrease of albumin leakage was observed, which was 0.90 ± 0.40 g/L at baseline, 0.67 ± 0.36 g/L on the 10 th day, and 0.43 ± 0.22g/L 20 days after the end of treatment. Within 10-day treatment period, use of sulodexide resulted in a reduction in the peritoneal loss of albumin, in addition to improvement of the quality of dialysis and the residual renal function among these patients.

    The high prevalence of protein-energy malnutrition is a critical issue for patients with end stage renal disease (ESRD) on hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). Levels of plasma and intracellular amino acids are significant indicators of protein metabolism and nutritional status assessment. We measured plasma FAAs in patients on maintenance dialysis and to provide information in monitoring the therapeutic strategy, particularly in AA supplementary therapy or protein restriction. Fifty-five patients with ESRD were investigated, 25 on HD (male : female=14 : 11; 48-67 y) and 30 on CAPD (male : female=17 : 13; 45-64 y). The subjects had been on dialysis for an average of 13 months (range, 9 to 22 months). Their plasma FAAs (including their intermediate metabolites) were measured by ion exchange chromatography before and after HD or during CAPD and were compared with data obtained from 20 age- and sex-matched healthy controls. The total plasma FAA levels (urea and free ammonia, NH3 were excluded) in pre-HD samples (3911 +/- 709 micromol/l) was significantly higher than in the other groups (2570 +/- 378 in control, 3210 +/- 640 in post-HD, and 3468 +/- 271 in CAPD samples). The mean plasma FAA concentrations differed significantly between pre-HD and controls and between pre-HD and CAPD samples (pplasma of patients with ESRD, possibly producing higher levels of the waste products (urea and NH3) through the urea cycle and ammonia metabolism in liver. Maintenance dialysis can effectively eliminate excess FAAs in plasma, as there was a 17.9% reduction post-HD. The abnormalities in FAA metabolism found in patients with ESRD necessitate careful consideration of dialysis and dietary measures.

    Full Text Available Background: Volume overload results in higher mortality rates in patients on continuous ambulatory peritoneal dialysis (CAPD. The ratio of bioimpedance (RBI might be a helpful parameter in adjusting dry body weight in CAPD patients. This study examined whether it is possible to distinguish between non-hypervolemic status and hypervolemic status in CAPD patients by using only RBI. Methods: RBI was calculated as follows: RBI = impedance at 50 kHz/impedance at 500 kHz. Based on the experts’ judgements, a total of 64 CAPD patients were divided into two groups, a non-hypervolemic group and a hypervolemic group.

Other RBIs were measured from the right side of the anterior superior iliac spine to the ipsilateral ankle (rasis-raRBI to control for the electro-physiological effects of peritoneal dialysate. Results: The mean rw-raRBI of non-hypervolemic patients was higher than that of hypervolemic patients in the presence (1.141 ± 0.022 vs. 1.121 ± 0.021, P < 0.001 of a peritosol. Likewise, the mean rasis-raRBI of non-hypervolemic patients was higher than that of hypervolemic patients (presence of peritosol: 1.136 ± 0.026 vs. 1.109 ± 0.022, P < 0.001; absence of peritosol: 1.131 ± 0.022 vs. 1.107 ± 0.022, P < 0.001. Conclusion: The volume status of CAPD patients was able to be simply expressed by RBI. Therefore, this study suggests that when patients cannot be analyzed using BCM, RBI could be an alternative.

    Objectives Taiwan succeeded in raising the proportion of peritoneal dialysis (PD) usage after the National Health Insurance (NHI) payment scheme introduced financial incentives in 2005. This study aims to compare the economic costs between automated PD (APD) and continuous ambulatory PD (CAPD) modalities from a societal perspective. Design and setting A retrospective cohort of patients receiving PD from the NHI Research Database was identified during 2004–2011. The 1:1 propensity score matched 1749 APD patients and 1749 CAPD patients who were analysed on their NHI-financed medical costs and utilisation. A multicentre study by face-to-face interviews on 117 APD and 129 CAPD patients from five hospitals located in four regions of Taiwan was further carried out to collect data on their out-of-pocket payments, productivity losses and quality of life with EuroQol-5D-5L. Outcome measures The NHI-financed medical costs, out-of-pocket payments and productivity losses of APD and CAPD patients. Results The total NHI-financed medical costs per patient-year after 5 years of follow-up were significantly higher with APD than CAPD (US$23 005 vs US$19 237; peconomic costs of APD (US$30 401) were similar to those of CAPD (US$29 939), even after bootstrap analysis (APD, US$28 399; CAPD, US$27 960). No discernable differences were found in the results of mortality and quality of life between the APD and CAPD patients. Conclusions APD had higher annual dialysis-related costs and lower annual productivity losses than CAPD, which made the economic costs of APD very close to those of CAPD in Taiwan. PMID:28325860

    Accurate evaluation of hematology analyzers is recommended before these devices can be broadly introduced for the routine testing of continuous ambulatory peritoneal dialysis (CAPD), ascitic, and pleural fluids. We evaluated the performance of Mindray BC-6800 for white blood cell (WBC) and differential cell count in 50 CAPD, 60 ascitic and 40 pleural compared with manual microscopy. Within-run precision, limit of blank (LoB), limit of detection (LoD), limit of quantitation (LoQ), and carryover were assessed. The Passing-Bablok regression in all fluids showed the following equations: y WBC =1.05x+3.31 (95%CI slope 0.95 to 1.12; intercept -0.25 to 5.52); y MN =0.85x+15.63 (95%CI slope 0.72 to 1.05; intercept -24.18 to 84.47); and y PMN =1.21x+13.37 (95%CI slope 1.03 to 1.35; intercept 4.00 to 32.47) with bias 78 cells/μL. The AUC for clinical PMN cut-off was 0.88 (95%CI: 0.77 to 0.98). In ascitic, pleural, and CAPD fluids the AUC for clinical PMN cut-off were 0.88 (95%CI: 0.63 to 1.00), 0.83 (95%CI: 0.68 to 0.99), and 1.00 (95%CI: 1.00 to 1.00) respectively. CV ranged from 3%-34%. LoB of 3 cell/μL was verified. LoD and LoQ reported the same result (8 cells/μL). Carry over never exceeded 0.05%. The effectiveness of BC-6800 to categorize cells from different body fluids was not compromised by the slight positive bias observed. This conclusion is supported by the high AUC and agreement between the automated method and the reference method. The results show that BC-6800 offers rapid, accurate, and reproducible results for clinical management of CAPD, ascitic, and pleural fluids. © 2017 Wiley Periodicals, Inc.

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

    Residual renal function needs to be assessed frequently in patients on continuous ambulatory peritoneal dialysis (CAPD). A commonly used method is to measure creatinine (Cr) and urea clearance in urine collected over 24 h, but collection can be cumbersome and difficult to manage. A faster, simpler alternative is to measure levels of cystatin C (CysC) in serum, but the accuracy and reliability of this method is controversial. Our study aims to validate published CysC-based equations for estimating residual renal function in patients on CAPD. Residual renal function was measured by calculating average clearance of urea and Cr in 24-h urine as well as by applying CysC- or Cr-based equations published by Hoek and Yang. We then compared the performance of the equations against the 24-h urine results. In our sample of 255 patients ages 47.9 ± 15.6 years, the serum CysC level was 6.43 ± 1.13 mg/L. Serum CysC level was not significantly associated with age, gender, height, weight, body mass index, hemoglobin, intact parathyroid hormone, normalized protein catabolic rate or the presence of diabetes. In contrast, serum CysC levels did correlate with peritoneal clearance of CysC and with levels of prealbumin and high-sensitivity C-reactive protein. Residual renal function was 2.56 ± 2.07 mL/min/1.73 m 2 based on 24-h urine sampling, compared with estimates (mL/min/1.73 m 2 ) of 2.98 ± 0.66 for Hoek's equation, 2.03 ± 0.97 for Yang's CysC-based equation and 2.70 ± 1.30 for Yang's Cr-based equation. Accuracies within 30%/50% of measured residual renal function for the three equations were 29.02/48.24, 34.90/56.86 and 31.37/54.90. The three equations for estimating residual renal function showed similar limits of agreement and differed significantly from the measured value. Published CysC-based equations do not appear to be particularly reliable for patients on CAPD. Further development and validation of CysC-based equations should take into account peritoneal clearance of

     To assess whether continuity of care with a general practitioner is associated with hospital admissions for ambulatory care sensitive conditions for older patients.  Cross sectional study.  Linked primary and secondary care records from 200 general practices participating in the Clinical Practice Research Datalink in England.  230 472 patients aged between 62 and 82 years and who experienced at least two contacts with a general practitioner between April 2011 and March 2013.  Number of hospital admissions for ambulatory care sensitive conditions (those considered manageable in primary care) per patient between April 2011 and March 2013.  We assessed continuity of care using the usual provider of care index, which we defined as the proportion of contacts occurring between April 2011 and March 2013 that were with the most frequently seen general practitioner. On average, the usual provider of care index score was 0.61. Continuity of care was lower among practices with more doctors (average score 0.59 in large practices versus 0.70 in small practices). Higher continuity of care was associated with fewer admissions for ambulatory care sensitive conditions. When modelled, controlling for demographic and clinical patient characteristics, an increase in the usual provider of care index of 0.2 for all patients would reduce these admissions by 6.22% (95% confidence interval 4.87% to 7.55%). There was greater evidence for an association among patients who were heavy users of primary care. Heavy users also experienced more admissions for ambulatory care sensitive conditions than other patients (0.36 admissions per patient for those with ≥18 contacts with a general practitioner, compared with 0.04 admissions per patient for those with 2-4 contacts).  Strategies that improve the continuity of care in general practice may reduce secondary care costs, particularly for the heaviest users of healthcare. Promoting continuity might also improve the experience of patients

    We found chronic pneumoperitoneum in two continuous ambulatory peritoneal dialysis patients from two different hospitals. Both patients used the Stay.Safe? system and bicaVera solution, whose extension tubing is not primed with fluid but air-filled, unlike that of the conventional solution bags. This fact, together with a handling fault common to both patients, resulted in the inflow of the air in the tubing of bicaVera bags into the peritoneal cavity during every exchange. We warn of this co...

    This study compared health-related quality of life in patients with early to mid-stage chronic kidney disease. This study utilized a comparative descriptive design. Patients receiving continuous ambulatory peritoneal dialysis were recruited from a hospital in Korea. Information from patients with stage 3 and 4 chronic kidney disease was obtained from Korean national survey data. A total of 75 pairs were matched using the propensity score method. Health-related quality of life was compared using the European Quality of Life-5 Dimensions questionnaire. Only 4% of patients with stage 3 or 4 chronic kidney disease are aware of their disease. These patients have decreased mobility and ability to perform their usual activities (χ(2)  = 10.77, P = 0.001; χ(2)  = 7.22, P = 0.007, respectively). However, they have lower levels of anxiety and depression than patients undergoing continuous ambulatory peritoneal dialysis (χ(2)  = 13.37, P chronic kidney disease. Educational intervention in asymptomatic patients is important to increase awareness and early detection of chronic kidney disease. © 2015 Japan Academy of Nursing Science.

    Cortical neural prosthetics extract command signals from the brain with the goal to restore function in paralyzed or amputated patients. Continuous control signals can be extracted from the motor cortical areas, whereas neural activity from posterior parietal cortex (PPC) can be used to decode cognitive variables related to the goals of movement. Because typical activities of daily living comprise both continuous control tasks such as reaching, and tasks benefiting from discrete control such as typing on a keyboard, availability of both signals simultaneously would promise significant increases in performance and versatility. Here, we show that PPC can provide 3D hand trajectory information under natural conditions that would be encountered for prosthetic applications, thus allowing simultaneous extraction of continuous and discrete signals without requiring multisite surgical implants. We found that limb movements can be decoded robustly and with high accuracy from a small population of neural units under free gaze in a complex 3D point-to-point reaching task. Both animals' brain-control performance improved rapidly with practice, resulting in faster target acquisition and increasing accuracy. These findings disprove the notion that the motor cortical areas are the only candidate areas for continuous prosthetic command signals and, rather, suggests that PPC can provide equally useful trajectory signals in addition to discrete, cognitive variables. Hybrid use of continuous and discrete signals from PPC may enable a new generation of neural prostheses providing superior performance and additional flexibility in addressing individual patient needs.

    Hand forces (HFs) are commonly measured during biomechanical assessment of manual materials handling; however, it is often a challenge to directly measure HFs in field studies. Therefore, in a previous study we proposed a HF estimation method based on ground reaction forces (GRFs) and body segment accelerations and tested it with laboratory equipment: GFRs were measured with force plates (FPs) and segment accelerations were measured using optical motion capture (OMC). In the current study, we evaluated the HF estimation method based on an ambulatory measurement system, consisting of inertial motion capture (IMC) and instrumented force shoes (FSs). Sixteen participants lifted and carried a 10-kg crate from ground level while 3D full-body kinematics were measured using OMC and IMC, and 3D GRFs were measured using FPs and FSs. We estimated 3D hand force vectors based on: (1) FP+OMC, (2) FP+IMC and (3) FS+IMC. We calculated the root-mean-square differences (RMSDs) between the estimated HFs to reference HFs calculated based on crate kinematics and the GRFs of a FP that the crate was lifted from. Averaged over subjects and across 3D force directions, the HF RMSD ranged between 10-15N when using the laboratory equipment (FP + OMC), 11-18N when using the IMC instead of OMC data (FP+IMC), and 17-21N when using the FSs in combination with IMC (FS + IMC). This error is regarded acceptable for the assessment of spinal loading during manual lifting, as it would results in less than 5% error in peak moment estimates. Copyright © 2017 Elsevier Ltd.

    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 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.

    DPAC.Objectives: To describe the elders with end stage renal disease (ESRD undergoing continuous ambulatory peritoneal dialysis (CAPD, their caregivers, and the care the caregivers provide to the elders. Methods: This was a qualitative study with 9 caregivers. Data were collected through oral history. Data analysis consisted of thematic content analysis. Results: The sample consisted of 5 male and 4 female elders and all them were dependent on caregivers to change the dialysis collection bag. The mean age of the participants was 70 years. Among the caregivers, 8 of them were female with a mean age of 41.5 years and they provided 8 hours of care to the elders daily. The main theme emerging from the content analysis was "home care for the elderly undergoing continuous ambulatory peritoneal dialysis." Conclusion: Caregivers need support for the development of knowledge and skills to deal with the elders' demand of care, particularly in regard to the management of CAPD.

    A 47-year-old man with end-stage renal disease due to diabetic nephropathy underwent a peritoneal scintigraphy to evaluate the cause of recently developed scrotal swelling. Two liters of dialystate mixed with 111 MBq of Tc-99m sulfur colloid were adminstered into the peritoneal cavity via the dialysis catheter. Various anterior images of the abdomen and pelvis were obtained at 15 min, 2 hr and 4 hr after the tracer instillation. At 15 min, anterior images of the abdomen and pelvis demonstrated linear tracts of activity through both inguinal canals, which were more prominent in the right side (A). Images at 2 hr revealed a passage of the radioactive fluid into the right hemiscrotum. At the same time, there was a considerable accumulation of activity in the right inguinal canal (B). In the delayed image, there was a progressive accumulation of activity in the inguinal canals and a prominent passage of the tracer into the scrotum (C). Both abdominal and inguinal hernias are commonly associated with continuous ambulatory peritoneal dialysis (CAPD). Overall incidence of CAPD-induced hernia ranges from 2.7% to 25%. Inguinal hernias were frequently manifested as scrotal swelling. Leakages f dialysate fluid into the scrotum has been noted in CAPD patients with scrotal swelling, with or without clincal findings of inguinal hernia. In the present case, the right side had leakage from a clinical inguinal hernia and the left side, leakage, from a subclinial inguinal hernia. A subclinical inguinal hernia was easily demonstrable with peritoneal scintigraphy. Peritoneal scintigraphy is extremely helpful in the evaluation of scrotal swelling in a patient on CAPD.

    The lifespan and outcome of end stage renal disease (ESRD) children have dramatically improved since the development of continuous ambulatory peritoneal dialysis (CAPD), it offers several advantages over hemodialysis. Percutaneous placement of CAPD catheters in children is minimally invasive, reliable, safe and cost-effective method. Percutaneous method of CAPD catheter insertion can be used in children to avoid the complications of general anesthesia and surgery. This study was done to evaluate the efficacy of CAPD in children, to find out the complication profile of CAPD & to compare the advantages of surgical versus percutaneously placed CAPD catheters in children. This prospective longitudinal comparative study was carried out in the department of Pediatric Nephrology, Dhaka Medical College Hospital (DMCH), Bangladesh from July 2011 to June 2014. A total of 8 children with ESRD were included (Age 5-14 year, M: F=1: 1). All underwent CAPD, Group I = surgically placed CAPD catheter (N=5), Group II = percutaneously placed CAPD catheter (N=3). Average duration of CAPD in Group I and Group II were 31.6 vs. 9 (months) with a total of 158 vs. 27 patient months of CAPD respectively. The rate of complications of the 2 groups and their outcome were compared. Common complications being observed were peritonitis 1 episode per 12.1 vs. 1.8 patient months (pchildren (pchildren, but percutaneous method of catheter insertion is associated with higher rate of complications. Placement of catheter by surgical method with elective omentectomy will reduce catheter related complications. Early detection of peritonitis and prompt therapy is essential for a favourable outcome.

    Peritonitis is the most frequent serious complication of continuous ambulatory peritoneal dialysis (CAPD). It has a major influence on the number of patients switching from CAPD to haemodialysis and has probably restricted the wider acceptance and uptake of CAPD as an alternative mode of dialysis.This is an update of a review first published in 2000. This systematic review sought to determine if modifications of the transfer set (Y-set or double bag systems) used in CAPD exchanges are associated with a reduction in peritonitis and an improvement in other relevant outcomes. We searched the Cochrane Renal Group's Specialised Register through contact with the Trials Search Co-ordinator. Studies contained in the Specialised Register are identified through search strategies specifically designed for CENTRAL, MEDLINE and EMBASE. Date of last search: 22 October 2013. Randomised controlled trials (RCTs) or quasi-RCTs comparing double bag, Y-set and standard peritoneal dialysis (PD) exchange systems in patients with end-stage kidney disease. Data were abstracted by a single investigator onto a standard form and analysed by Review Manager. Analysis was by a random effects model and results were expressed as risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI). Twelve eligible trials with a total of 991 randomised patients were identified. Despite the large total number of patients, few trials covered the same interventions, small numbers of patients were enrolled in each trial and the methodological quality was suboptimal. Y-set and twin-bag systems were superior to conventional spike systems (7 trials, 485 patients, RR 0.64, 95% CI 0.53 to 0.77) in preventing peritonitis in PD. Disconnect systems should be the preferred exchange systems in CAPD.

    The purpose of this review is to discuss current practices and changes in the field of ambulatory anesthesia, in both hospital and ambulatory surgery center settings. New trends in ambulatory settings are discussed and a review of the most current and comprehensive guidelines for the care of ambulatory patients with comorbid conditions such as postoperative nausea and vomiting (PONV), obstructive sleep apnea and diabetes mellitus are reviewed. Future direction and challenges to the field are highlighted. Ambulatory anesthesia continues to be in high demand for many reasons; patients and surgeons want their surgical procedures to be swift, involve minimal postoperative pain, have a transient recovery time, and avoid an admission to the hospital. Factors that have made this possible for patients are improved surgical equipment, volatile anesthetic improvement, ultrasound-guided regional techniques, non-narcotic adjuncts for pain control, and the minimization of PONV. The decrease in time spent in a hospital also decreases the risk of wound infection, minimizes missed days from work, and is a socioeconomically favorable model, when possible. Recently proposed strategies which will allow surgeons and anesthesiologists to continue to meet the growing demand for a majority of surgical cases being same-day include pharmacotherapies with less undesirable side-effects, integration of ultrasound-guided regional techniques, and preoperative evaluations in appropriate candidates via a telephone call the night prior to surgery. Multidisciplinary communication amongst caregivers continues to make ambulatory settings efficient, safe, and socioeconomically favorable.It is also important to note the future impact that healthcare reform will have specifically on ambulatory anesthesia. The enactment of the Patient Protection and Affordable Care Act of 2010 will allow 32 million more people to gain access to preventive services that will require anesthesia such as screening

The body mass index (BMI) of CAPD patients was 23.9 kg/m 2 versus 21.7 kg/m 2 of the IHD (P = 0.04). The systolic and diastolic blood pressure of CAPD patients were 158 and 89 mm Hg in comparison to 141 and 72 mm Hg in IHD patients (P <0.001) and their total and low-density lipoprotein cholesterol level were 5.93 mmol/L and 3.84 mmol/L versus 4.79 mmol/L and 2.52 mmol/L, respectively (P≤0.001). The CAPD patients were hyperglycemic more than IHD patients, although it was not statistically significant. All the nontraditional CV risk factors except serum albumin were comparable between the two groups. Serum albumin in CAPD patients was 35.5 g/L compared to 40.8 g/L in the IHD patients (P <0.001). In our prevalent dialysis-dependent patients, both traditional and non-traditional CV risk factors are common. Due to the prolonged and continuous glucose exposure from the peritoneal dialysis fluid, the CAPD patients had highly

    A retrospective case-comparison study. Compare efficacy and safety of combined intrathecal morphine (ITM) and epidural analgesia (EPI) to that of conventional intravenous patient-controlled analgesia (IV-PCA) after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). Pain control after PSF in AIS has been managed traditionally with IV-PCA. More recently studies have shown improvement in pain control with the use of continuous EPI or intraoperative ITM. No studies to our knowledge have compared the use of both ITM and EPI analgesia to that of IV-PCA. An Institutional Review Board-approved retrospective case-comparison study was performed from 1989 to 2009 of all patients undergoing PSF for AIS. Patients received either IV-PCA or ITM/EPI. Daily pain scores were recorded along with total opioid and benzodiazepine use. Adverse events were recorded for all the patients. A total of 146 patients were initially included in the study; 95 patients received ITM/EPI and 51 received IV-PCA as a historical control. Eight patients from the ITM/EPI group were excluded from the pain comparison portion of the study. There were no statistical differences in age, sex, weight, or hospital stay between the 2 groups. The ITM/EPI group had, on average, 1 additional level of fusion (P = 0.001). Daily average pain scores were lower in the ITM/EPI group on all hospital days, and statistically lower in days 1 and 3 to 5. Total opioid requirement was significantly lower in the ITM/EPI patients, although oral opioid use was higher among this group. Total benzodiazepine use was lower among the IV-PCA group. A total of 15.7% of the IV-PCA patients had bladder hypotonia, compared with 1.1% of the ITM/EPI group (P = 0.002). The rate of illeus was 15.7% in the IV-PCA patients and 5.7% in the ITM/EPI (P = 0.071). Respiratory depression was reported in 4 ITM/EPI patients, 0 in our PCA group. Technical catheter malfunction was reported in 8.5% of the EPI group. The use of ITM

    goat skin throughout the 2-year experimental period without any special wound care such as cleansing or disinfection. The performance of the skin-penetrating pad was similarly favorable when attached to a commercial continuous ambulatory peritoneal dialysis catheter. The newly developed segmented polyurethane porous material had excellent tissue biocompatibility and tissue ingrowth. The skin-penetrating pad devised by using this porous material did not cause epidermal downgrowth, suggesting that it may be effective for the prevention of exit-site infection.

    Continuous ambulatory peritoneal dialysis (CAPD) is an alternative to the hemodialysis mode of terminal renal failure treatment. Nutritional status impairment is common among patients with end-stage renal disease, and its laboratory surrogates predict increased morbidity and mortality risk in patients on chronic haemodialysis or peritoneal dialyses. The aetiology of malnutrition is multifactorial and delayed gastric emptying is also considered to be a significant factor. The aim of this study was to estimate the direct influence of indwelled dialysate in the peritoneal cavity on gastric emptying in patients treated with CAPD. The study group included 20 patients (9 males, 11 females) aged 50,1 ± 11 years (range: 39-75 years) with chronic renal failure treated with CAPD for 18.4 ± 14.7 months. All patients were non-diabetic and had no other than chronic uraemia co-morbidity known to influence autonomic nervous system function and gastric motility. The control group included 15 healthy volunteers matched by age, sex and body weight. Dialysis adequacy parameters were calculated based on 24-hour urine and dialysate collections. Gastric emptying was estimated with dynamic abdominal scintigraphy. We compared the results of gastric emptying tests performed in dialysed patients with and without dialysate liquid in the peritoneal cavity and related the values to those of the control subjects. In the study group, weekly values of dialysis parameters were within the ranges considered satisfactory in terms of uraemia control. All parameters of gastric emptying were significantly delayed and prolonged in terminal renal failure patients, but the results have shown no significant differences between those with and without indwelling dialysate. Based on the results we conclude that gastric emptying in subjects with chronic renal failure treated with CAPD is markedly delayed compared to healthy subjects. There was no significant effect of indwelling dialysate in the peritoneal

    Background and Purpose Relatively little is known about the natural evolution of physical activity-related participation restrictions associated with Parkinson disease (PD). We examined this issue prospectively using continuous monitoring technology to capture the free-living ambulatory activity of persons living with PD engaging in life situations. We specifically sought (1) to explore natural, long-term changes in daily ambulatory activity, and (2) to compare the responsiveness of ambulatory activity parameters to clinical measures of gait and disease severity. Methods Thirty-three persons with PD participated (Hoehn and Yahr range of 1–3). Participants wore a step activity monitor for up to 7 days at baseline and again at 1-year follow-up. Mean daily values were calculated for parameters indicative of amount, intensity, frequency, and duration of ambulatory activity. Clinical measures included the Unified Parkinson Disease Rating Scale, the 6-Minute Walk, and Maximal Gait Speed. Parametric tests for paired samples were used to investigate changes in ambulatory activity parameters and clinical measures. Results Participants had significant declines in the amount and intensity of daily ambulatory activity but not in its frequency and duration (p < 0.007). Declines occurred in the absence of changes in clinical measures of gait or disease severity. The greatest 1-year decline occurred in the number of daily minutes participants spent engaging in at least moderate-intensity ambulatory activity. Conclusion Continuous monitoring of ambulatory activity beyond mere step counts may serve as a distinct and important means of quantifying declining ambulatory behavior associated with disease progression or improved ambulatory behavior resulting from rehabilitation, medical, and / or surgical interventions in persons with PD.

    Malnutrition is highly prevalent in patients on continuous ambulatory peritoneal dialysis (CAPD) and is a strong predictor of increased morbidity and mortality. Therefore, the aim of this study was to evaluate the effect of oral administration of an egg albumin-based protein supplement on the nutritional status of CAPD patients. In this randomized, open label, controlled clinical trial, 28 CAPD patients were allocated to a study (n = 13) or a control (n = 15) group. Both groups received conventional nutritional counseling; the study group received, additionally, an oral egg albumin-based supplement. During a 6-month follow-up, all patients had monthly clinical and biochemical evaluations and quarterly assessments of adequacy of dialysis and nutrition. Serum albumin Levels were not different between groups; however, a significant increase (baseline vs final) was observed in the study group (2.64+/-0.35 vs 3.05+/-0.72 g/dL) but not in the control group (2.66+/-0.56 vs 2.80+/-0.54 mg/dL). Calorie and protein intake increased more in the study group (calories 1331+/-432 vs 1872+/-698 kcal; proteins 1.0+/-0.3 vs 1.7+/-0.7 g/kg) than in the control group (calories 1423+/-410 vs 1567+/-381 kcal; proteins 1.0+/-0.4 vs 1.0+/-0.3 g/kg). Similarly, non-protein nitrogen appearance rate (nPNA) increased significantly more in the study (1.00+/-0.23 vs 1.18+/-0.35 g/kg/day) than in the control group (0.91+/-0.11 vs 0.97+/-0.14 g/kg/ day). Triceps skinfold thickness (TSF) and midarm muscle area (MAMA) displayed a nonsignificant trend to a greater increase in the study group (TSF 16.7+/-8.7 vs 18.3+/-10.7 mm; MAMA 23.8+/-6.2 vs 25.8+/-5.9 cm2) than in controls (TSF 16.4+/-5.7 vs 16.9+/-7.0 mm; MAMA 28.7+/-7.8 vs 30.0+/-7.9 cm2). At the end of follow-up, the frequency of patients with moderate or severe malnutrition decreased 6% in the control group and decreased 28% in the study group. At the final evaluation, the most important predictors of serum albumin were the oral egg albumin

    This study aimed to compare the clinical and radiographic success of preveneered posterior NuSmile® and Kinder Krowns® over one year and to assess the level of parental satisfaction with their esthetics. Three trained operators placed 120 crowns in a split-mouth design with a random allocation for 36 participants (mean age: 5.8 years) who received two, four, six, or eight crowns. Blind assessment of the clinical and radiographic performance of the restorations was performed by four calibrated examiners after one year. Results were analyzed by Fisher's exact test and McNemar test. Examiner reliability was determined by Cohen's kappa score. Visual analogue scale (VAS) was used to assess the level of parental satisfaction. All crowns but one were retained, and the majority (83 percent) had no facing fractures. Parental satisfaction was high (9.4/10 on the VAS). Primary maxillary first molar crowns had more occlusal facing fractures than their mandibular counterparts (P=.02). Primary mandibular second molar crowns showed more facing fractures than their maxillary counterparts (P=.008). Both types showed no statistical difference in most categories, but Kinder Krowns had more facing fractures (Pcrowns have predictable durability at 12 months while offering natural appearance to restored teeth.

    Full Text Available Background/Aim. Morbidity and mortality of continous ambulatory peritoneal dialysis (CAPD patients is still very high. The aim of the study was to evaluate the effects of peritoneal dialysis (PD solutions (standard vs biocompatible on long-term patients’ and the techique survival. Methods. A total of 42 stable patients on CAPD participated in this crosssectional study. They were prospectively followed-up during the twelve years. Patients with severe anemia (Hb 1 mm; carotid narrowing degree > 50%, presence of carotid plaques in both common carotide, ischaemic heart disease, cerebrovascular event and peripheral vascular disease with or without amputation were independent predictors of overall patient survival. Duration of dialysis was only independent predictor of overall technique survival. Conclusion. Although patients treated with biocompatible solutions showed significantly better survival, the role of biocompatibility of CAPD solutions in patients and technique survival have to be confirmed. Namely, multivariate analysis confirmed that duration of dialysis, serum triglyceride and cardiovascular score significantly predicted overall CAPD patients survival, while only duration of dialysis was found to be independent predictor of overall techique survival.

    O'Donnell, Brian D

    2012-02-03

    PURPOSE OF REVIEW: The purpose of this review is to present advances in the use of regional anesthetic techniques in ambulatory orthopedic surgery. New findings regarding the use of both neuraxial anesthesia and peripheral nerve block are discussed. RECENT FINDINGS: Neuraxial anesthesia: The use of short-acting local anesthetic agents such as mepivacaine, 2-chloroprocaine, and articaine permits rapid onset intrathecal anesthesia with early recovery profiles. Advantages and limitations of these agents are discussed.Peripheral nerve block: Peripheral nerve blocks in limb surgery have the potential to transform this patient cohort into a truly ambulatory, self-caring group. Recent trends and evidence regarding the benefits of regional anesthesia techniques are presented.Continuous perineural catheters permit extension of improved perioperative analgesia into the ambulatory home setting. The role and reported safety of continuous catheters are discussed. SUMMARY: In summary, shorter acting, neuraxial, local anesthetic agents, specific to the expected duration of surgery, may provide superior recovery profiles in the ambulatory setting. A trend towards more peripheral and selective nerve blocks exists. The infrapatellar block is a promising technique to provide analgesia following knee arthroscopy. Improved analgesia seen in the perioperative period can be safely and effectively extended to the postoperative period with the use of perineural catheters.

    Background In the current health care environment more patient care has moved from in-hospital care to the ambulatory primary care settings; however, fewer internal medicine residents are pursuing primary care careers. Barriers to residents developing a sense of competency and enjoyment in ambulatory medicine include the complexity of practice-based systems, patients with multiple chronic diseases, and the limited time that residents spend in the outpatient setting. Objective In an effort to accelerate residents' ambulatory care competence and enhance their satisfaction with ambulatory practice, we sought to change the learning environment. Interns were provided a series of intensive, focused, ambulatory training sessions prior to beginning their own continuity clinic sessions. The sessions were designed to enable them to work confidently and effectively in their continuity clinic from the beginning of the internship year, and it was hoped this would have a positive impact on their perception of the desirability of ambulatory practice. Methods Improvement needs assessment after a performance, so we developed a structured, competency-based, multidisciplinary curriculum for initiation into ambulatory practice. The curriculum focused on systems-based practice, patient safety, quality improvement, and collaborative work while emphasizing the importance of continuity of care and long-term doctor-patient relationships. Direct observation of patient encounters was done by an attending physician to evaluate communication and physical examination skills. Systems of care commonly used in the clinic were demonstrated. Resources for practice-based learning were used. Conclusion The immersion of interns in an intensive, hands-on experience using a structured ambulatory care orientation curriculum early in training may prepare the intern to be a successful provider and learner in the primary care ambulatory setting.

    The aims of this study were to compare several DNA extraction methods and 16S rDNA primers and to evaluate the clinical utility of broad-range PCR in continuous ambulatory peritoneal dialysis (CAPD) culture fluids. Six type strains were used as model organisms in dilutions from 10(8) to 10(0) colony-forming units (CFU)/mL for the evaluation of 5 DNA extraction methods and 5 PCR primer pairs. Broad-range PCR was applied to 100 CAPD culture fluids, and the results were compared with conventional culture results. There were some differences between the various DNA extraction methods and primer sets with regard to the detection limits. The InstaGene Matrix (Bio-Rad Laboratories, USA) and Exgene Clinic SV kits (GeneAll Biotechnology Co. Ltd, Korea) seem to have higher sensitivities than the others. The results of broad-range PCR were concordant with the results from culture in 97% of all cases (97/100). Two culture-positive cases that were broad-range PCR-negative were identified as Candida albicans, and 1 PCR-positive but culture-negative sample was identified as Bacillus circulans by sequencing. Two samples among 54 broad-range PCR-positive products could not be sequenced. There were differences in the analytical sensitivity of various DNA extraction methods and primers for broad-range PCR. The broad-range PCR assay can be used to detect bacterial pathogens in CAPD culture fluid as a supplement to culture methods.

    Full Text Available Context : Pediatric cataract surgery is traditionally done with the aid of high-molecular-weight viscoelastics which are expensive. It needs to be determined if low-cost substitutes are just as successful. Aims : The study aims to determine the success rates for anterior and posterior capsulorrhexis and intraocular lens (IOL implantation in the bag for pediatric cataract surgery performed with the aid of a low-molecular-weight viscoelastic. Settings and Design : Nonrandomized observational study. Materials and Methods: Children less than 6 years of age who underwent cataract surgery with IOL implantation in the period May 2008-May 2009 were included. The surgeries were done by pediatric ophthalmology fellows. A standard procedure of anterior capsulorrhexis, lens aspiration with primary posterior capsulorrhexis, anterior vitrectomy, and IOL implantation was followed. Three parameters were studied: successful completion of anterior and posterior capsulorrhexis and IOL implantation in the bag. Results: 33 eyes of 28 children were studied. The success rate for completion was 66.7% and 88.2 % for anterior and posterior capsulorrhexis, respectively. IOL implantation in the bag was successful in 87.9%. Conclusions: 2% hydroxypropylmethylcellulose is a viable low-cost alternative to more expensive options similar to high-molecular-weight viscoelastics. This is of great relevance to hospitals in developing countries.

    Increasingly larger series of laparoscopic fundoplications (LF) are being reported. A well-documented advantage of the laparoscopic approach is shortened hospital stay. Most centers report typical lengths of stay (LOS) for LF of 2-3 days. Our success with LF with a LOS of 1 day led to an attempt at performing LF on an ambulatory basis. Sixty-one consecutive patients with appropriate criteria for LF underwent surgery at our institution. Patients were counseled by the authors as to the usual postop course and progression of diet. All patients received preemptive analgesia (PEA) consisting of perioperative ketorolac and preincisional local infiltration with bupivicaine. Anesthetic management included induction with propofol, high-dose inhalational anesthetics, minimizing administration of parenteral narcotics, and avoidance of reversal of neuromuscular blockade. Immediate postop pain management included parenteral ketorolac and oral hydro- or oxycodone. All patients were given oral fluids and soft solids after transfer from the recovery room to the postoperative observation unit. Two patients were excluded from ambulatory consideration due to excessive driving distance from our hospital. Another two were hospitalized for observation after experiencing intraoperative technical problems. Of 57 patients in whom same-day discharge was attempted, there were three failures requiring overnight hospitalization: All were due to pain and nausea; one patient also suffered transient urinary retention. There were no adverse outcomes related to early discharge, and there were no readmissions. One patient returned to the emergency room after delayed development of urinary retention. Median time from conclusion of operation to discharge was less than 5 h. No patients expressed dissatisfaction with early discharge on follow-up interview. LF can be safely performed as an ambulatory procedure. Analgesic and anesthetic management should be tailored to minimize nausea and provide adequate

    OBJECTIVES: The aim of this study was to study low dose hypobaric 0.15% bupivacaine and hyperbaric 0.5% bupivacaine in outpatient anorectal surgical procedures. METHODS: Two groups of 50 patients, physical status ASA I and II, undergoing anorectal surgical procedures in a jackknife position, received 6 mg of hypobaric 0.15% bupivacaine in the surgical position (Group 1 or 6 mg of hyperbaric 0.5% bupivacaine in the sitting position for 5 minutes, after which they were placed in a jackknife position (Group 2. Sensitive and motor blockade, time of first urination, ambulation, complications, and the need for analgesics were evaluated. Patients were followed until the third postoperative day and questioned whether they experienced post-puncture headache or temporary neurological symptoms, and until the 30th day and questioned about permanent neurological complications. The test t Student, Mood's median, and Fisher Exact test were used for statistical analysis, and a p < 0.05 was considered significant. RESULTS: Every patient in Group 1 presented selective blockade of the posterior sacral nerve roots, while patients in Group 2 experienced blockade of the anterior and posterior nerve roots. Blockade was significantly higher in Group 1. Motor blockade was significantly less severe in Group 1. Forty-nine patients in Group 1 transferred to the stretcher unassisted while only 40 patients in Group 2 were able to do so. Recovery in Group 1 occurred in 105 ± 25 minutes and in 95 ± 15 minutes in Group 2, and this difference was not statistically significant. There were no hemodynamic changes, nausea or vomiting, urine retention, or post-puncture headache. CONCLUSIONS: Anorectal surgical procedures under spinal block with low dose bupivacaine, hyperbaric or hypobaric, can be safely done.

    for practicing in a managed care environment, and help staff communicate with a culturally diverse patient population and promote the importance of primary care within the community. Significant innovations and improvements were realized through the projects. Several hospitals expanded the availability of primary care services, trained new primary care providers, and helped patients gain access to primary care clinicians for the first time. Better methods for documenting ambulatory care were introduced. To increase efficiency and improve service to patients, some of the hospitals instituted automated appointment systems and improved medical record services. To reduce fragmentation and contain personnel costs, support staff positions were redesigned, and staff were retrained to carry out new multi-tasked responsibilities. Many of the components vital to high-quality ambulatory care can take years to develop, and significant investments of capital. Increased primary care capacity, new specialty group practices, state-of-the-art equipment for diagnosis and treatment, advanced information technology to manage and coordinate care and link services at multiple locations, and highly trained clinical and support staff all require strong commitment and support from a team of senior management executives and medical staff leaders, sufficient staffing resources, and outside expertise. Once the infrastructure is in place, hospitals must continue to reach out to their communities, helping people to understand the health care system and use it effectively.

    Full Text Available Alexander R Facque, Peter J Taub Division of Plastic and Reconstructive Surgery, Department of Surgery, Mount Sinai Medical Center, New York, NY, USA Abstract: In 2013, there were 17 million procedures performed by plastic and reconstructive surgeons in the United States in the private office or ambulatory “surgicenter” setting, as well as additional operations performed in hospitals on an outpatient basis. As interest in performing increasingly complex surgical procedures on an outpatient basis continues to grow, the surgeon and anesthesiologist alike must be prepared to offer safe and reliable anesthesia and analgesia in the ambulatory setting. Surgeons must be aware of the possible techniques that will be employed in their surgeries in order to anticipate and prepare patients for possible postoperative side effects, and anesthesiologists must be prepared to offer such techniques in order to ensure a relatively rapid return to normal activity despite potentially having undergone major surgery. The following is a review of the specific considerations that should be given to ambulatory plastic surgery patients with comments on recent developments in the techniques used to safely administer agreeable and effective anesthesia.

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

    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.

    Full Text Available Ushma Shah, David T Wong, Jean Wong Department of Anesthesia, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, Canada Abstract: Most surgeries in North America are performed on an ambulatory basis, reducing health care costs and increasing patient comfort. Patient satisfaction is an important outcome indicator of the quality of health care services incorporated by the American Society of Anesthesiologists (ASA. Patient satisfaction is a complex concept that is influenced by multiple factors. A patient's viewpoint and knowledge plays an influential role in patient satisfaction with ambulatory surgery. Medical optimization and psychological preparation of the patient plays a pivotal role in the success of ambulatory surgery. Postoperative pain, nausea, and vomiting are the most important symptoms for the patient and can be addressed by multimodal drug regimens. Shared decision making, patient–provider relationship, communication, and continuity of care form the main pillars of patient satisfaction. Various psychometrically developed instruments are available to measure patient satisfaction, such as the Iowa Satisfaction with Anesthesia Scale and Evaluation du Vecu de I'Anesthesie Generale, but none have been developed specifically for ambulatory surgery. The ASA has made recommendations for data collection for patient satisfaction surveys and emphasized the importance of reporting the data to the Anesthesia Quality Institute. Future research is warranted to develop a validated tool to measure patient satisfaction in ambulatory surgery. Keywords: patient, satisfaction, anesthesia, outcomes, questionnaire, perspectives

    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.

    Side effect incidences after ambulatory (22G needle and two h bed rest) and after non-ambulatory (22 and 20G needles and 20 h bed rest) lumbar iohexol myelography have been estimated and compared. Headache incidence was significantly greater in ambulatory (50%, n=107) as compared to nonambulatory myelography (26%, n=58). Headaches in the ambulatory group tended to be of shorter duration and the difference between severe headaches in ambulatory and non-ambulatory groups was not significant. Serious adverse reactions did not occur and none of the ambulatory patients required readmission because of side effects. The headache was predominantly postural and occurred significantly earlier in the ambulatory group. Headache incidence was significantly greater after 20G needle myelography (44%, n=97) as compared to 22G needle iohexol myelography (26%, n=58). The results support the hypothesis that CSF leakage is a major cause of headache after lumbar iohexol myelography. (orig.)

    To assess the safety and feasibility of ambulatory percutaneous nephrolithotomy (PCNL). PCNL is the gold standard for the management of large renal stones. Although tubeless PCNL has been previously described, no case series have been published of ambulatory PCNL. The criteria for ambulatory PCNL were: single tract, stone-free status documented by flexible nephroscopy, adequate pain control, and satisfactory postoperative hematocrit level and chest radiographic findings. Patient information, including operating room and fluoroscopy times, stone size and Hounsfield units, and number of needle punctures, were collected prospectively. The time spent in the recovery room, in addition to the amount of narcotics used in the recovery room and at home, was documented. Of 10 patients, 8 had nephrostomy tracts established intraoperatively by the urologist and 2 had preoperative nephrostomy tubes placed. The median operating and fluoroscopy time was 83.5 and 4.45 minutes, respectively. The median stone diameter was 20 mm (800 Hounsfield units) in addition to a patient with a staghorn calculus. The patients spent a median of 240 minutes in the recovery room and had received a median of 19.25 mg of morphine equivalents. Only 3 patients (30%) used narcotics at home. No intraoperative complications occurred, and none of the patients required transfusions. Two postoperative complications developed: a deep vein thrombosis requiring outpatient anticoagulation and multiresistant Escherichia coli infection requiring intravenous antibiotics. In highly selected patients, ambulatory PCNL is safe and feasible. More patients are needed to verify the criteria for patients undergoing the ambulatory approach. Copyright © 2010 Elsevier Inc.

    A retrospective study investigated 24 ambulatory pediatric patients with spastic cerebral palsy and neuromuscular scoliosis. To evaluate the effect of spinal fusion from T1-T2 to the sacrum with pelvic fixation using unit rod instrumentation on the ambulatory potential of these patients. Spinal deformities in patients with cerebral palsy and good ambulatory capacity are infrequently associated with pelvic obliquity, so instrumented spinal fusions traditionally do not extend to the pelvis. The medical charts and radiographs were reviewed, and the patients' ambulatory ability was assessed clinically with videotape or complete gait analysis. A questionnaire assessing patients' functional improvement was given to the caretakers. The study group included 17 female and 7 male patients, among whom were 19 quadriplegics and 5 diplegics. The mean age at surgery was 15.4 years. Of the 24 patients, 20 underwent posterior spinal fusion and 4 had combined anteroposterior procedures. The patients were evaluated clinically before surgery and after surgery. Follow-up evaluations of ambulatory function occurred at a mean of 2.86 years after surgery. No alteration in the ambulatory status of the patients was found, except in one patient who experienced bilateral hip heterotopic ossification and gradually lost her ability to ambulate. Preoperative and postoperative gait analysis was performed for 12 patients, showing no change in their ambulatory function. The surgical outcome survey demonstrated significant improvement in the patients' physical appearance, head and trunk balance, sitting ability, and respiration, with no change in ambulatory capacity. Spine surgery with fusion extending to the pelvis in ambulatory patients with cerebral palsy provided excellent deformity correction and preserved their ambulatory function.

    Full Text Available Anne B Chin, Elizabeth C Wick Department of Surgery, The Johns Hopkins University School of Medicine, Baltimore, MD, USA Abstract: Surgical site infections (SSIs are frequent postoperative complications that are linked to measures of surgical quality and payment determinations. As surgical procedures are increasingly performed in the ambulatory setting, management of SSIs must transition with this trend. Prevention of SSIs should include optimization of patient comorbidities, aggressive infection control policies including appropriate skin decontamination, maintenance of normothermia, and appropriate antibiotic prophylaxis. Systems must also be set in place to provide adequate surveillance for identification of SSIs when they do occur as well as provide direct feedback to surgeons regarding SSI rates. This may require utilization of claims-based surveillance. Patient education and close follow-up with the clinical team are essential for early identification and management of SSIs. Therapy should remain focused on source control and appropriate antibiotic therapy. Keywords: ambulatory surgery, SSI, infection

    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.

No patient was in stupor or coma and no patient experienced a lucid interval. Only one patient had signs referable to the posterior fossa. Two patients had occipital skull fracture disclosed by plain radiographs. CT revealed a unilateral biconvex hematoma in two cases, and a bilateral hematoma with supratentorial extension in the third. All patients underwent suboccipital craniectomy and recovered. Therapeutic success in these cases was facilitated by early CT and the rapid disclosure of the unsuspected posterior fossa lesions. CT showing contiguous hematoma below and above the tentorium cerebelli after posterior head trauma is highly suggestive of epidural hematoma arising from the posterior fossa. (orig.)

Provision of appropriate pain relief is still often inadequate in this setting; poor pain control and adverse effects of opioids provided for pain control are common reasons for readmission, with human and economic consequences. Therefore, improved analgesia after ambulatory surgery is an important goal; appropriate strategies include identification of at-risk patients, provision of multimodal analgesia, and early use of rescue strategies. Multimodal analgesia is based on the combined use of multiple medications or techniques for pain control, which have different mechanisms of action or act on different sites at the pain pathways. Thereby, such an approach improves analgesia, reduces opioid requirements, and reduces adverse effects of opioids. Important components of multimodal analgesia are nonopioids (acetaminophen and anti-inflammatory drugs, corticosteroids, and alpha-2-delta modulators (gabapentin, pregabalin, but most importantly the use of local and regional anesthesia techniques. Here, the use of adjuvants is one way to increase the duration of pain relief, but, increasingly, continuous peripheral nerve blocks via catheters are used in ambulatory patients, too. Finally, the planning of discharge medications needs a balancing act between the requirements for provision of good analgesia and the risk of opioids going out into the community.

French Association for Ambulatory Surgery and International Association for Ambulatory Surgery adopted a limited list of 18 reference procedures to launch a survey on the prevalence of ambulatory surgery. The prevalence rate of ambulatory procedures among this list raised from 35.2% to 39.3% in 1999. This rate was the same in public and private health institutions. Ambulatory practice was increasing more than the inpatient procedures. Intercountry comparisons pointed out France as the tenth country for ambulatory prevalence among 13 members of Organization for Economic Cooperation and Development. This underlined the fact that there was probably a growth potential for ambulatory surgery in France.

    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.

    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. 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. 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. 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. 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 cleft surgery enhances overall health care value.

    Full Text Available History of present illness: A 15-year old female presented with left elbow pain. While competing in a high school wrestling match, she extended her left arm to brace a fall and had immediate onset of sharp pain. She denied weakness or numbness of her left arm. She had no past medical history. Significant findings: Elbow dislocations are classified by the position of the radio-ulnar joint relative to the humerus.1 Images 1, 2, and 3 show a left posterior elbow dislocation; the radius and ulna are displaced posteriorly with respect to the distal humerus. The lateral view of the elbow most clearly shows this: trochlear notch of the ulna is empty and displaced posteriorly relative to the trochlea. There is no associated fracture. Images 4 and 5 show the elbow status-post reduction, demonstrating proper alignment of the distal humerus with the radius and ulna. Discussion: Traumatic dislocations of the elbow are relatively uncommon in pediatric patients, with a peak incidence at 13 to 14 years.1 Dislocations are usually posterior and occur after forced abduction and extension of the elbow.1 It is important to evaluate for an associated fracture or avulsion, which occurs in over 50% of pediatric elbow dislocations. Fractures most commonly involve the medial epicondyle, radial head and neck, or coronoid process.1 One should also consider a neurovascular injury to the ulnar or median nerve or to the brachial artery or its branches.1 Posterior elbow dislocations should be reduced as soon as possible.1 Patients should receive adequate sedation and/or analgesia. One method of reduction is the “puller” technique, during which a practitioner stabilizes the humerus, while a second practitioner applies force against the anterior forearm, with gentle traction distally.1 Post-reduction neurovascular reassessment is important. After successful reduction, patients can be immobilized in a posterior long arm splint.

Tracheal diverticula are usually recognized radiologically as solitary right paratracheal air collections on thoracic computed tomography examination. They are usually asymptomatic but can occasionally present with persistent symptoms. We herein report the case of a 50-year-old male patient who underwent extensive evaluation for persistent cough. Multiple posterior right paratracheal air collections were recognized on thoracic multidetector computed tomography examination, which was confirmed as multiple-acquired posterior upper tracheal diverticula on flexible bronchoscopy. The patient improved with conservative medical management.

  10. Posterior Urethral Valves

    Full Text Available The most common cause of lower urinary tract obstruction in male infants is posterior urethral valves. Although the incidence has remained stable, the neonatal mortality for this disorder has improved due to early diagnosis and intensive neonatal care, thanks in part to the widespread use of prenatal ultrasound evaluations. In fact, the most common reason for the diagnosis of posterior urethral valves presently is the evaluation of infants for prenatal hydronephrosis. Since these children are often diagnosed early, the urethral obstruction can be alleviated rapidly through catheter insertion and eventual surgery, and their metabolic derangements can be normalized without delay, avoiding preventable infant mortality. Of the children that survive, however, early diagnosis has not had much effect on their long-term prognosis, as 30% still develop renal insufficiency before adolescence. A better understanding of the exact cause of the congenital obstruction of the male posterior urethra, prevention of postnatal bladder and renal injury, and the development of safe methods to treat urethral obstruction prenatally (and thereby avoiding the bladder and renal damage due to obstructive uropathy are the goals for the care of children with posterior urethral valves[1].

    To evaluate safety, efficacy, and patient's satisfaction of an ambulatory phlebectomy, performed at a radiology outpatient clinic. Between 2003 and 2006, an ambulatory phlebectomy was performed in 12 patients. Endovenous radiofrequency ablation was performed through a venotomy. The venotomy was ligated after RF ablation, and the ambulatory phlebectomy was performed. The patients visited the radiology outpatient clinic one day, one week, and 2 months after the procedure. The improvement in the clinical symptoms, cosmetic change in varicosity, and the procedure related complications were evaluated. The patient's satisfaction was evaluated using a 5-grade scale. RF ablation through a venotomy was performed successfully in all 12 patients. On average, 4.5 incisions were made, and 12.5 cm of varicosity had been removed. The mean procedure time was one hour and forty minutes. The complications of the ambulatory phlebectomy were bruising in one patient, and skin pigmentation in another. The complications associated with RF ablation were a hard palpable vein in 7 patients, numbness in 7 patients, and skin pigmentation along the vein in 2 patients. Follow-up duplex sonography was performed at 2 months after the procedure, showed complete occlusion in all 12 patients. The clinical symptoms had improved in 11 patients, and the varicosity disappeared cosmetically in 11 patients. An ambulatory phlebectomy, combined with RF ablation of the greater saphenous vein, can be performed safely and effectively at a radiology outpatient clinic.

    A business-practice model is a guide, or toolkit, to assist managers and clinical pharmacy practitioners in the exploration, proposal, development and implementation of new clinical pharmacy services and/or the enhancement of existing services. This document was developed by the American College of Clinical Pharmacy Task Force on Ambulatory Practice to assist clinical pharmacy practitioners and administrators in the development of business-practice models for new and existing clinical pharmacy services in ambulatory settings. This document provides detailed instructions, examples, and resources on conducting a market assessment and a needs assessment, types of clinical services, operations, legal and regulatory issues, marketing and promotion, service development and exit plan, evaluation of service outcomes, and financial considerations in the development of a clinical pharmacy service in the ambulatory environment. Available literature is summarized, and an appendix provides valuable citations and resources. As ambulatory care practices continue to evolve, there will be increased knowledge of how to initiate and expand the services. This document is intended to serve as an essential resource to assist in the growth and development of clinical pharmacy services in the ambulatory environment.

    On March 1-2, 2010, a state-of-the-science invitational conference titled "Ambulatory Care Registered Nurse Performance Measurement" was held to focus on measuring quality at the RN provider level in ambulatory care. The conference was devoted to ambulatory care RN performance measurement and quality of health care. The specific emphasis was on formulating a research agenda and developing a strategy to study the testable components of the RN role related to care coordination and care transitions, improving patient outcomes, decreasing health care costs, and promoting sustainable system change. The objectives were achieved through presentations and discussion among expert inter-professional participants from nursing, public health, managed care, research, practice, and policy. Conference speakers identified priority areas for a unified practice, policy, and research agenda. Crucial elements of the strategic dialogue focused on issues and implications for nursing and inter-professional practice, quality, and pay-for-performance.

    2005-01-01

    The Posterior Reversible Encephalopathy Syndrome (PRES) is a clinical Syndrome composed of cephalea, alteration in vision and convulsions, usually observed in patients with sudden elevation of arterial pressure. The imagenologic evidence shows reversible vasogenic brain edema without stroke. Its location is predominantly posterior; it affects the cortex and the subcortical white matter of the occipital, parietal and temporal lobes. The treatment with antihypertensive drugs and the removing of immunosupressor medication are generally associated with complete neurological recovery; this is reflected also in the images which return to their basal condition. The untreated hypertension, on the other side, can result in a progressive defect of the autoregulation system of the central nervous system with cerebral hemorrhage, irreversible brain stroke, coma and death

  18. Ambulatory anesthesia and postoperative nausea and vomiting: predicting the probability

Research in this area is plentiful and has focused on event prediction and pharmacological prophylaxis but despite this, postoperative nausea and vomiting (PONV typically occurs in 20%–30% of patients in contemporary practice. Prediction of postoperative and postdischarge nausea and vomiting is particularly important in the ambulatory surgical population as these symptoms may occur following discharge from hospital and continue for up to one week when access to antiemetic therapies is limited. Many of the existing predictive scoring systems are based on data from inpatient populations and limited to the first 24 hours after surgery. Scoring systems based on data from ambulatory surgical populations to predict PONV are only moderately good. The best-performing systems in ambulatory patients are those of Sinclair and Sarin with an area under the receiver operating characteristic curve of 0.78 and 0.74, respectively, but are limited by the short duration of follow-up and a greater emphasis on nausea than vomiting. Given that the ability to predict both PONV and postdischarge nausea and vomiting is clearly limited, emphasis has been placed on prophylactic strategies that incorporate antiemetic medication, intravenous hydration, and nonnarcotic analgesia. PONV has been reduced to <10% in institutions using multimodal approaches. Scoring systems may facilitate “risk tailoring” in which patient risk profile is used as a stratification method for pharmacointervention.

    Surgical treatment of thoracolumbar osteomyelitis consists of radical debridement, reconstruction of anterior column either with or without posterior stabilization. The objective of present study is to evaluate a case series of patients with osteomyelitis of thoracic and lumbar spine treated by single, posterior approach with posterior instrumentation and anterior column reconstruction. Seventeen patients underwent clinical and radiological evaluation pre and postoperatively with latest follow-up at 19 months (8-56 months) after surgery. Parameters assessed were site of infection, causative organism, angle of deformity, blood loss, duration of surgery, ICU stay, deformity correction, time to solid bony fusion, ambulatory status, neurologic status (ASIA impairment scale), and functional outcome (Kirkaldy-Willis criteria). Mean operating time was 207 min and average blood loss 1,150 ml. Patients spent 2 (1-4) days in ICU and were able to walk unaided 1.6 (1-2) days after surgery. Infection receded in all 17 patients postoperatively. Solid bony fusion occurred in 15 out of 17 patients (88 %) on average 6.3 months after surgery. Functional outcome was assessed as excellent or good in 82 % of cases. Average deformity correction was 8 (1-18) degrees, with loss of correction of 4 (0-19) degrees at final follow-up. Single, posterior approach addressing both columns poses safe alternative in treatment of pyogenic vertebral osteomyelitis of thoracic and lumbar spine. It proved to be less invasive resulting in faster postoperative recovery.

    Full Text Available Objective: To determine resident comfort and skill in performing ambulatory care skills. Methods: Descriptive survey of common ambulatory care skills administered to internal medicine faculty and residents at one academic medical center. Respondents were asked to rate their ability to perform 12 physical exam skills and 6 procedures, and their comfort in performing 7 types of counseling, and obtaining 6 types of patient history (4 point Likert scale for each. Self-rated ability or comfort was compared by gender, status (year of residency, faculty, and future predicted frequency of use of the skill. Results: Residents reported high ability levels for physical exam skills common to both the ambulatory and hospital setting. Fewer felt able to perform musculoskeletal, neurologic or eye exams easily alone. Procedures generally received low ability ratings. Similarly, residents’ comfort in performing common outpatient counseling was also low. More residents reported feeling very comfortable in obtaining history from patients. We found little variation by gender, year of training, or predicted frequency of use. Conclusion: Self-reported ability and comfort for many common ambulatory care skills is low. Further evaluation of this finding in other training programs is warranted.

    Full Text Available Abstract The correct implementation of Ambulatory Surgery must be accompanied by an accurate monitoring of the patient post-discharge state. We fit different statistical models to predict the first hours postoperative status of a discharged patient. We will also be able to predict, for any discharged patient, the probability of needing a closer follow-up, or of having a normal progress at home. Background The status of a discharged patient is predicted during the first 48 hours after discharge by using variables routinely used in Ambulatory Surgery. The models fitted will provide the physician with an insight into the post-discharge progress. These models will provide valuable information to assist in educating the patient and their carers about what to expect after discharge as well as to improve their overall level of satisfaction. Methods A total of 922 patients from the Ambulatory Surgery Unit of the Dr. Peset University Hospital (Valencia, Spain were selected for this study. Their post-discharge status was evaluated through a phone questionnaire. We pretend to predict four variables which were self-reported via phone interviews with the discharged patient: sleep, pain, oral tolerance of fluid/food and bleeding status. A fifth variable called phone score will be built as the sum of these four ordinal variables. The number of phone interviews varies between patients, depending on the evolution. The proportional odds model was used. The predictors were age, sex, ASA status, surgical time, discharge time, type of anaesthesia, surgical specialty and ambulatory surgical incapacity (ASI. This last variable reflects, before the operation, the state of incapacity and severity of symptoms in the discharged patient. Results Age, ambulatory surgical incapacity and the surgical specialty are significant to explain the level of pain at the first call. For the first two phone calls, ambulatory surgical incapacity is significant as a predictor for all

    To review reversible posterior leukoencephalopathy syndrome. We reviewed 22 patients (M:F=3:19; age, 17-46 years) with the characteristic clinical and imaging features of reversible posterior leukoencephalopathy syndrome. All underwent brain MRI, and in three cases both CT and MRI were performed. In one, MRA was obtained, and in eleven, follow-up MR images were obtained. We evaluated the causes of this syndrome, its clinical manifestations, and MR findings including the locations of lesions, the presence or absence of contrast enhancement, and the changes seen at follow-up MRI. Of the 22 patients, 13 had eclampsia (six during pregnancy and seven during puerperium). Four were receiving immunosuppressive therapy (three, cyclosporine ; one, FK 506). Four suffered renal failure and one had complicated migraine. The clinical manifestations included headache (n=12), visual disturbance (n=13), seizure (n=15), focal neurologic sign (n=3), and altered mental status (n=2). Fifteen patients had hypertension and the others normotension. MRI revealed that lesions were bilateral (n=20) or unilateral (n=2). In all patients the lesion was found in the cortical and subcortical areas of the parieto-occipital lobes ; other locations were the basal ganglia (n=9), posterior temporal lobe (n=8), frontal lobe (n=5), cerebellum (n=5), pons (n=2), and thalamus (n=1). All lesions were of high signal intensity on T2-weighted images, and of iso to low intensity on T1-weighted images. One was combined with acute hematoma in the left basal ganglia. In eight of 11 patients who underwent postcontrast T1-weighted MRI, there was no definite enhancement ; in one, enhancement was mild, and in tow, patchy. CT studies showed low attenuation, and MRA revealed mild vasospasm. The symptoms of all patients improved. Follow-up MRI in nine of 11 patients depicted complete resolution of the lesions ; in two, small infarctions remained but the extent of the lesions had decreased. Reversible posterior

Emergency management includes suprapubic tube placement. Subsequent primary realignment to place a urethral catheter remains a controversial topic, but what is not controversial is that when there is the development of a stricture (which is usually obliterative with a distraction defect after suprapubic tube placement or urethral catheter removal, the standard of care is delayed urethral reconstruction with excision and primary anastomosis.

    2017-02-01

    Under the new categorization introduced by the Health Authorities, ambulatory surgery (AS) in France now accounts for 50% of procedures, taking all surgical specialties together. The replacement of full hospital admission by AS is now well established and recognized. Health-care centers have learned, in coordination with the medico-surgical and paramedical teams, how to set up AS units and the corresponding clinical pathways. There is no single model handed down from above. The authorities have encouraged these developments, partly by regulations but also by means of financial incentives. Patient eligibility and psychosocial criteria are crucial determining factors for the success of the AS strategy. The surgeons involved are strongly committed. Feedback from many orthopedic subspecialties (shoulder, foot, knee, spine, hand, large joints, emergency and pediatric surgery) testify to the rise of AS, which now accounts for 41% of all orthopedic procedures. Questions remain, however, concerning the role of the GP in the continuity of care, the role of innovation and teaching, the creation of new jobs, and the attractiveness of AS for surgeons. More than ever, it is the patient who is "ambulatory", within an organized structure in which surgical technique and pain management are well controlled. Not all patients can be eligible, but the AS concept is becoming standard, and overnight stay will become a matter for medical and surgical prescription. Copyright © 2016 Elsevier Masson SAS.

    2014-12-15

    To design and evaluate a doctor of pharmacy course exploring disease states commonly encountered in ambulatory care, while applying literature to clinical practice and promoting a continual learning mindset. This elective incorporated a learner-centered teaching approach. Each week, 2 groups of students were assigned a clinical trial to present to their peers. The focus was on clinical application and impact, rather than literature evaluation. A social networking group on Facebook was used to expose students to pharmacy information outside the classroom. Student grades were determined by multiple activities: presentations, participation and moderation of the Facebook group, class participation, quiz scores, and quiz question development. Course evaluations served as a qualitative assessment of student learning and perceptions, quizzes were the most objective assessment of student learning, and presentation evaluations were the most directed assessment of course goals. This elective was an innovative approach to teaching ambulatory care that effectively filled a curricular void. Successful attainment of the primary course goals and objectives was demonstrated through course evaluations, surveys, and quiz and presentation scores.

    Indirect posterior composite inlays and onlays are a valuable part of the cosmetic dentist's repertoire of services. They fulfill most of the requirements for an esthetic alternative to the previously considered amalgam, gold, porcelain, and directly placed composite restorations. As in all other cosmetic dental procedures, attention to detail is essential for success. Improving technology will continue to have an impact on the place these restorations occupy in future cosmetic practice.

    Full Text Available History of present illness: A 22-year-old male presented to the Emergency Department complaining of right shoulder pain after a motocross accident. He was traveling at approximately 10 mph around a turn when he lost control and was thrown over the handlebars, landing directly on his right shoulder. On arrival, he was holding his arm in adduction and internal rotation. An area of swelling was noted over his anterior shoulder. He was unable to abduct his shoulder. No humeral gapping was noted. He had normal neuro-vascular status distal to the injury. Significant findings: Radiographs demonstrated posterior displacement of the humeral head on the “Y” view (see white arrow and widening of the glenohumeral joint space on anterior-posterior view (see red arrow. The findings were consistent with posterior dislocation and a Hill-Sachs type deformity. Sedation was performed and reduction was attempted using external rotation, traction counter-traction. An immediate “pop” was felt during the procedure. Post-procedure radiographs revealed a persistent posterior subluxation with interlocking at posterior glenoid. CT revealed posterior dislocation with acute depressed impaction deformity medial to the biceps groove with the humeral head perched on the posterior glenoid, interlocked at reverse Hill-Sachs deformity (see blue arrow. Discussion: Posterior shoulder dislocations are rare and represent only 2% of all shoulder dislocations. Posterior shoulder dislocations are missed on initial diagnosis in more than 60% of cases.1 Posterior shoulder dislocations result from axial loading of the adducted and internally rotated shoulder, violent muscle contractions (resulting from seizures or electrocution, a direct posterior force applied to the anterior shoulder.1 Physical findings include decreased anterior prominence of the humeral head, increased palpable posterior prominence of the humeral head below the acromion, increased palpable prominence of the

    Full Text Available Abstract Progressive posterior cortical dysfunction (PPCD is an insidious syndrome characterized by prominent disorders of higher visual processing. It affects both dorsal (occipito-parietal and ventral (occipito-temporal pathways, disturbing visuospatial processing and visual recognition, respectively. We report a case of a 67-year-old woman presenting with progressive impairment of visual functions. Neurologic examination showed agraphia, alexia, hemispatial neglect (left side visual extinction, complete Balint's syndrome and visual agnosia. Magnetic resonance imaging showed circumscribed atrophy involving the bilateral parieto-occipital regions, slightly more predominant to the right . Our aim was to describe a case of this syndrome, to present a video showing the main abnormalities, and to discuss this unusual presentation of dementia. We believe this article can contribute by improving the recognition of PPCD.

    Academic general pediatrics and ambulatory care are closely linked to the development of the Ambulatory Pediatric Association, an organization with nearly 2000 members active in teaching, patient care, and research. Primary care, behavioral-developmental pediatrics, prevention, health promotion, community pediatrics, socioeconomic issues, cultural and ethnic diversity, advocacy, research in education, social issues, and environmental health lie within the purview of general pediatrics. In part, because of their teaching and patient care obligations, but also due to a lack of fellowship research training, many general pediatrics faculty have had difficulty in accomplishing significant research. By supporting fellowship training in general pediatrics, The Robert Wood Johnson Foundation General Pediatrics Academic Development Program and the current fellowship program supported by the Bureau of Health Manpower are important efforts to remedy this deficiency. The sciences basic to general pediatrics research include epidemiology, biostatistics, and the behavioral sciences. In addition, general pediatrics research often borrows from other sciences and collaborates with investigators in other disciplines. Partnerships between general pediatrics divisions and practicing pediatricians for teaching and research, e.g. the Community Education in Community Settings program, provides a realistic educational program for future pediatricians. The Pediatric Research in Office Setting network is another important vehicle for translation of research into the practice of general pediatrics. The steady growth of the Ambulatory Pediatric Association over the past four decades is testimony to the creativity, adaptability, and verve that has characterized the discipline of general pediatrics.

    Academic health systems face challenges in the governance and oversight of quality and safety efforts across their organizations. Ambulatory practices, which are growing in number, size, and complexity, face particular challenges in these areas. In February 2014, leaders at Johns Hopkins Medicine (JHM) implemented a governance, oversight, and accountability structure for quality and safety efforts across JHM ambulatory practices. This model was based on the fractal approach, which balances independence and interdependence and provides horizontal and vertical support. It set expectations of accountability at all levels from the Board of Trustees to frontline staff and featured a cascading structure that reached all units and ambulatory practices. This model leveraged an Ambulatory Quality Council led by a physician and nurse dyad to provide the infrastructure to share best practices, continuously improve, and define accountable local leaders. This model was incorporated into the quality and safety infrastructure across JHM. Improved outcomes in the domains of patient safety/risk reduction, externally reported quality measures, patient care/experience, and value have been demonstrated. An additional benefit was an improvement in Medicaid value-based purchasing metrics, which are linked to several million dollars of revenue. As this model matures, it will serve as a mechanism to align quality standards and programs across regional, national, and international partners and to provide a clear quality structure as new practices join the health system. Future efforts will link this model to JHM's academic mission, enhancing education to address Accreditation Council for Graduate Medical Education core competencies.

    Full Text Available Objective. Study objectives were to assess temporal trends and identify patient- and practice-level predictors of the prescription of antiplatelet medications in a national sample of ischemic stroke (IS patients seeking ambulatory care. Methods. IS-related outpatient visits by adults were identified using the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey for the years 2000–2007. We assessed prescribing of antiplatelet medications using the generic drug code and drug entry codes in these data. Temporal trends in antiplatelet prescribing were assessed using the Cochran-Mantel-Haenszel test for trend. Results. We identified 9.5 million IS-related ambulatory visits. Antiplatelet medications were prescribed at 35.5% of visits. Physician office prescribing of the clopidogrel-aspirin combination increased significantly from 0.5% in 2000 to 22.0% in 2007 (P=0.05, whereas prescribing of aspirin decreased from 17.9% to 7.0% (P=0.50 during the same period. Conclusion. We observed a continued increase in prescription of the aspirin-clopidogrel combination from 2000 to 2007. Clinical trial evidence suggests that the aspirin-clopidogrel combination does not provide any additional benefit compared with clopidogrel alone; however, our study findings indicate that even with lack of adequate clinical evidence physician prescribing of this combination has increased in real-world community settings.

Meta-analyses and reviews of acupuncture and related techniques for postoperative nausea and vomiting (POVN and postoperative vomiting (POV show promising results while many clinicians remain skeptical of the value of acupuncture. Given the interest in finding safe non-pharmacological approaches toward postoperative care, this body of knowledge needs to be considered. This review critically appraises and summarizes the research on acupuncture and acupressure in ambulatory anesthesia during the last 15 years.Methods: Articles were identified through searches of Medline, PubMed, and Embase using the search terms “acupuncture” or “acupuncture therapy” in combination with “ambulatory anesthesia” or “ambulatory surgery” or “day surgery” or “postoperative”. A corresponding search was done using “acupressure” and “wristbands”. The searches generated a total of 104, 118, and 122 references, respectively.Results: Sixteen studies were included; eight studies reported on acupuncture and eight on acupressure. Nine studies found acupuncture or acupressure effective on primary endpoints including postoperative nausea and vomiting, postoperative pain, sore throat, and emergence agitation. Four studies found acupuncture had a similar effect to antiemetic medication.Conclusion: Overall, the studies were of fairly good quality. A large proportion of the reviewed papers highlights an effect of acupuncture or acupressure on postoperative morbidities in an ambulatory setting

    Full Text Available Jorinde AW Polderman, Robert van Wilpe, Jan H Eshuis, Benedikt Preckel, Jeroen Hermanides Department of Anaesthesiology, Academic Medical Centre, University of Amsterdam, Amsterdam, the Netherlands Abstract: Given the growing number of patients with diabetes mellitus (DM and the growing number of surgical procedures performed in an ambulatory setting, DM is one of the most encountered comorbidities in patients undergoing ambulatory surgery. Perioperative management of ambulatory patients with DM requires a different approach than patients undergoing major surgery, as procedures are shorter and the stress response caused by surgery is minimal. However, DM is a risk factor for postoperative complications in ambulatory surgery, so should be managed carefully. Given the limited time ambulatory patients spend in the hospital, improvement in management has to be gained from the preanesthetic assessment. The purpose of this review is to summarize current literature regarding the anesthesiologic management of patients with DM in the ambulatory setting. We will discuss the risks of perioperative hyperglycemia together with the pre-, intra-, and postoperative considerations for these patients when encountered in an ambulatory setting. Furthermore, we provide recommendations for the optimal perioperative management of the diabetic patient undergoing ambulatory surgery.

  7. Optimising postoperative pain management in the ambulatory patient.

    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

    Hypertension is a major global health problem, but prevalence rates vary widely among regions. To determine prevalence, treatment, and control rates of hypertension, we measured conventional blood pressure (BP) and 24-hour ambulatory BP in 6546 subjects, aged 40 to 79 years, recruited from 10 community-dwelling cohorts on 3 continents. We determined how between-cohort differences in risk factors and socioeconomic factors influence hypertension rates. The overall prevalence was 49.3% (range between cohorts, 40.0%-86.8%) for conventional hypertension (conventional BP ≥140/90 mm Hg) and 48.7% (35.2%-66.5%) for ambulatory hypertension (ambulatory BP ≥130/80 mm Hg). Treatment and control rates for conventional hypertension were 48.0% (33.5%-74.1%) and 38.6% (10.1%-55.3%) respectively. The corresponding rates for ambulatory hypertension were 48.6% (30.5%-71.9%) and 45.6% (18.6%-64.2%). Among 1677 untreated subjects with conventional hypertension, 35.7% had white coat hypertension (23.5%-56.2%). Masked hypertension (conventional BP hypertension rates. Higher social and economic development, measured by the Human Development Index, was associated with lower rates of conventional and ambulatory hypertension. In conclusion, high rates of hypertension in all cohorts examined demonstrate the need for improvements in prevention, treatment, and control. Strategies for the management of hypertension should continue to not only focus on preventable and modifiable risk factors but also consider societal issues. © 2017 American Heart Association, Inc.

    2014-01-01

    Diagnosing a posterior vitreous detachment (PVD) is important for predicting the prognosis and determining the indication for vitreoretinal surgery in many vitreoretinal diseases. This article presents both classifications of a PVD by slit-lamp biomicroscopy and of a shallow PVD by optical coherence tomography (OCT). By biomicroscopy, the vitreous condition is determined based on the presence or absence of a PVD. The PVD then is classified as either a complete posterior vitreous detachment (C-PVD) or a partial posterior vitreous detachment (P-PVD). A C-PVD is further divided into a C-PVD with collapse and a C-PVD without collapse, while a P-PVD is divided into a P-PVD with shrinkage of the posterior hyaloid membrane (P-PVD with shrinkage) and a P-PVD without shrinkage of the posterior hyaloid membrane (P-PVD without shrinkage). A P-PVD without shrinkage has a subtype characterized by vitreous gel attachment through the premacular hole in a posterior hyaloid membrane to the macula (P-PVD without shrinkage [M]). By OCT, a shallow PVD is classified as the absence of a shallow PVD or as a shallow PVD. A shallow PVD is then subclassified as a shallow PVD without shrinkage of the posterior vitreous cortex, a shallow PVD with shrinkage of the posterior vitreous cortex, and a peripheral shallow PVD. A shallow PVD without shrinkage of the posterior vitreous cortex has two subtypes: an age-related shallow PVD and a perifoveal PVD associated with a macular hole. PMID:24376338

    Quality improvement is considered part of "business as usual" in the health care field. Some institutions have progressed further into their quality improvement efforts than others. Nonetheless, there is always the opportunity to learn from the efforts of others and to adopt their methods for use in one's own setting when possible. Included in this article is a case study outlining the use of the FOCUS PDCA methodology for quality improvement. The information identifies ways of introducing and beginning quality improvement efforts in a way that can be translated into other ambulatory health care settings.

    Full Text Available Background. The incidence of spine metastasis is expected to increase as the population ages, and so is the number of palliative spinal procedures. Minimally invasive procedures are attractive options in that they offer the theoretical advantage of less morbidity. Purpose. The purpose of our study was to evaluate whether minimally invasive posterior spinal instrumentation provided significant pain relief and improved function. Study Design. We compared pre- and postoperative pain scores as well as ambulatory status in a population of patients suffering from oncologic conditions in the spine. Patient Sample. A consecutive series of patients with spine tumors treated minimally invasively with stabilization were reviewed. Outcome Measures. Visual analog pain scale as well as pre- and postoperative ambulatory status were used as outcome measures. Methods. Twenty-four patients who underwent minimally invasive posterior spinal instrumentation for metastasis were retrospectively reviewed. Results. Seven (29% patients were unable to ambulate secondary to pain and instability prior to surgery. All patients were ambulating within 2 to 3 days after having surgery (=0.01. The mean visual analog scale value for the preoperative patients was 2.8, and the mean postoperative value was 1.0 (=0.001. Conclusion. Minimally invasive posterior spinal instrumentation significantly improved pain and ambulatory status in this series.

    The general goals for treating an acetabular fracture are to restore congruity and stability of the hip joint. These goals are no different from those for the subset of fractures of the posterior wall. Nevertheless, posterior wall fractures present unique problems compared with other types of acetabular fractures. Successful treatment of these fractures depends on a multitude of factors. The physician must understand their distinctive radiologic features, in conjunction with patient factors, to determine the appropriate treatment. By knowing the important points of posterior surgical approaches to the hip, particularly the posterior wall, specific techniques can be used for fracture reduction and fixation in these often challenging fractures. In addition, it is important to develop a complete grasp of potential complications and their treatment. The evaluation and treatment protocols initially developed by Letournel and Judet continue to be important; however, the surgeon also should be aware of new information published and presented in the past decade.

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. Disability is a major predictor of exercise participation (at moderate to vigorous levels in both ambulatory and non-ambulatory

    To report outcomes of retinal detachment (RD) repair following posterior open globe injury. This retrospective, consecutive case series examined patients who underwent RD repair following Zone II and/or III open globe injury repair between January 1, 2007 and October 31, 2013. Patients with retina was achieved in 25 (83%) during the first vitreoretinal surgical procedure and 5 (17%) were deemed inoperable intraoperatively. Ten patients (30%) developed recurrent RD, and 8 underwent additional surgery. At last follow-up, reattachment was observed in 4 of these 8. The overall rate of final reattachment was 63% (19 patients). The mean number of surgeries for RD was 1.5 (range, 1-3). Fifteen patients (50%) achieved final visual acuity of counting fingers or better. Mean follow-up from the last vitreoretinal surgery was 23 months (range, 3-52). Although RD following posterior open globe injury confers a grave prognosis, successful anatomic reattachment of the retina was achieved in the majority of patients in this series, with half achieving ambulatory vision.

    The traditional method of management of posterior epistaxis has been with anteroposterior nasal packing. Apart from the high failure rate of 26-50% reported in various series, nasal packing is associated with marked discomfort and several complications. In order to avoid nasal packing, we started doing endoscopic cauterization in cases of posterior epistaxis. A total of 23 patients with posterior epistaxis were subjected to nasal endoscopy with the intent to stop bleeding by cauterization of the bleeding vessel. Of these, in four cases unsuspected diagnosis was made. Of the remaining 19, in three patients, the bleeding point could not be localized accurately and these patients were managed by anteroposterior packing. The rest of the 16 patients were managed by endoscopic cauterization. In four patients, there was recurrence of bleeding within 24 h. In one of these, cauterization controlled the bleeding while in the rest nasal packing had to be resorted to. Thus, of the 23 patients of posterior epistaxis subjected to nasal endoscopy, we could avoid nasal packing in 17 (74%). To conclude, endoscopic nasal cauterization is recommended as the first line to treatment in all cases of posterior epistaxis. This will not only prevent the uncomfortable and potentially dangerous nasal packing but also help in finding the underlying pathology.

    Analysis of our experience in 'in situ' ambulatory shockwave extracorporeal lithofragmentation of ureteral stones in 104 patients seen in the Lithotrity Unit, Urology Service, Fundación "Jiménez Díaz". Using Modulith SL 20, a third generation lithotripter, 'in situ' disintegration was achieved in 82.69% of cases, 51.92% of which were fragmented in a single lithotrity session. As a first choice, no ureteral handling was used in any of the patients prior to lithotrity. In 9.62% of patients it was necessary to place a 'double J' by-pass catheter, due to the disease presenting with a septic picture. The patient's position was either dorsal or ventral decubitus depending on the lithiatic site, while location and focusing of the stones was done radiologically. All patients were treated ambulatory without hospitalization. Only 18% was given oral or i.v. anaesthesia. Fursemide 40 mg was administered to all patients shortly before starting the session. Each patient received an average of 3,200 shockwaves per session (14-18 Kv, average 16 Kv). Haematuria was the single and modest side effect that happened during the 24 hours following lithofragmentation in 30% of patients, while 20% reported slight discomfort at the time of eliminating the gritted stones. We conclude stating that 'in situ' shockwave extracorporeal lithotrity of ureteral stones with Modulith SL 20 allows for elective disintegration of ureteral stones in whatever location they are found, due to the patient's easy positioning. The simple location and focusing of ureteral stones has allowed us to treat and solve some cases of ureteral lithiasis at the precise moment of the nephritic colic painful emergency, thus speeding up and facilitating the resolution of the condition. Our results and our strategy imply a new change of direction in the management of these lithiasis, as opposed to the well established and historical doctrines in existence regarding stones with ureteral location.

    Currently, many clinicians who help with breastfeeding problems are diagnosing "posterior" tongue-tie in infants and performing or referring for frenotomy. In this "Speaking Out" article, I argue that the diagnosis of "posterior" tongue-tie has successfully raised awareness of the importance of impaired tongue function in breastfeeding difficulty. However, the diagnosis of "posterior" tongue-tie also applies a reductionist, medicalized theoretical frame to the complex problem of impaired tongue function, risking unintended outcomes. Impaired tongue function arises out of multiple interacting and co-evolving factors, including the interplay between social behaviors concerning breastfeeding and mother-infant biology. Consideration of theoretical frames is vital if we are to build an evidence base through efficient use of the scarce resources available for clinical breastfeeding research and minimize unintended outcomes.

    Full Text Available Background. Posterior fossa epidural hematomas represent 7-14% of all traumatic intracranial epidural hematomas. They are most frequently encountered posttraumatic mass lesions in the posterior fossa. The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma. Methods. Between 1980 and 2002, 28 patients with epidural hematoma of the posterior fossa were operated on at the Institute for Neurosurgery, Belgrade. Clinical course neuroradiological investigations, and the results of surgical treatment of the patients with posterior fossa epidural hematomas were analyzed retrospectively. Results. Almost two thirds of patients were younger than 16 years of age. In 20 cases injury was caused by a fall, in 6 cases by a traffic accident, and in 2 by the assault. Clinical course was subacute or chronic in two thirds of the patients. On the admission Glasgow Coma Scale was 7 or less in 9 injured, 8-14 in 14 injured, and 15 in 5 injured patients. Linear fracture of the occipital bone was radiographically evident in 19 patients, but was intraoperatively encountered in all the patients except for a 4-year old child. In 25 patients the diagnosis was established by computer assisted tomography (CAT and in 3 by vertebral angiography. All the patients were operated on via suboccipital craniotomy. Four injured patients who were preoperatively comatose were with lethal outcome. Postoperatively, 24 patients were with sufficient neurologic recovery. Conclusion. Posterior fossa epidural hematoma should be suspected in cases of occipital injury, consciousness disturbances, and occipital bone fracture. In such cases urgent CAT-scan is recommended. Early recognition early diagnosis, and prompt treatment are crucial for good neurological recovery after surgery.

    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.

    Full Text Available Further cholestrol lowering may affect silent ischemia detected on holter monitoring. Cholesterol lowering is associated with a reduction in cardiovascular morbidity and mortality. Statins are the main drugs for cholesterol lowering. Ezetimibe when added to statins gives further reduction in cholesterol but its long-term effect on cardiovascular morbidity and mortality and ischemic events is not known. This study sought to determine whether further cholesterol lowering with ezitimibe will also results in a reduction of myocardial ischemia during daily life. We enrolled 50 patients with proven stable coronary artery disease (CAD and at least one episode of ST-segment depression on ambulatory ECG monitoring. All of them were receiving optimal therapy for CAD including statin therapy for cholesterol reduction. 25 patients were randomized to continue their statin therapy (Statin only group and 25 to recieve statin plus ezitimibe 10 mg/day (ezitimibe group. Serum cholesterol and LDL cholesterol levels and ambulatory monitoring were repeated after 4–6 months of therapy. The two groups were comparable with respect to baseline characteristics, number of episodes of ST-segment depression, and baseline serum cholesterol levels. The ezitimibe group had lower mean total and LDL cholesterol levels at study end and experienced a significant reduction in the number of episodes of ST-segment depression compared with the statin only group. ST-segment depression was completely resolved in 13 of 25 patients (52% in the ezitimibe group versus 3 of 25 (12% in the statin only group. The ezitimibe group exhibited a highly significant reduction in ambulatory ischemia (P < .001. By logistic regression, treatment with ezitimibe was an independent predictor of ischemia resolution. Further cholesterol lowering with ezitimibe can result in reduction or resolution of myocardial ischemia recorded as episodes of ST-segment depression in ambulatory monitoring of the ECG.

  4. Utilization of lean management principles in the ambulatory clinic setting.

    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.

    The American College of Cardiology Adult Congenital and Pediatric Cardiology (ACPC) Section had attempted to create quality metrics (QM) for ambulatory pediatric practice, but limited evidence made the process difficult. The ACPC sought to develop QMs for ambulatory pediatric cardiology practice. Five areas of interest were identified, and QMs were developed in a 2-step review process. In the first step, an expert panel, using the modified RAND-UCLA methodology, rated each QM for feasibility and validity. The second step sought input from ACPC Section members; final approval was by a vote of the ACPC Council. Work groups proposed a total of 44 QMs. Thirty-one metrics passed the RAND process and, after the open comment period, the ACPC council approved 18 metrics. The project resulted in successful development of QMs in ambulatory pediatric cardiology for a range of ambulatory domains. Copyright © 2017 American College of Cardiology Foundation.

    To determine the incidence of pseudarthrosis at the osteotomy site after three-column spinal osteotomies (3-COs) with posterior column reconstruction. 82 consecutive adult 3-COs (66 patients) with a minimum of 2-year follow-up were retrospectively reviewed. All cases underwent posterior 3-COs with two-rod constructs. The inferior facets of the proximal level were reduced to the superior facets of the distal level. If that was not possible, a structural piece of bone graft either from the local resection or a local rib was slotted in the posterior column defect to re-establish continual structural posterior bone across the lateral margins of the resection. No interbody cages were used at the level of the osteotomy. There were 34 thoracic osteotomies, 47 lumbar osteotomies and one sacral osteotomy with a mean follow-up of 52 (24-126) months. All cases underwent posterior column reconstructions described above and the addition of interbody support or additional posterior rods was not performed for fusion at the osteotomy level. Among them, 29 patients underwent one or more revision surgeries. There were three definite cases of pseudarthrosis at the osteotomy site (4%). Six revisions were also performed for pseudarthrosis at other levels. Restoration of the structural integrity of the posterior column in three-column posterior-based osteotomies was associated with > 95% fusion rate at the level of the osteotomy. Pseudarthrosis at other levels was the second most common reason for revision following adjacent segment disease in the long-term follow-up.

    Physicians' interest in investing and practicing in independent ambulatory surgery centers (ASCs) has grown. In the face of physician involvement in ASC development, healthcare organizations must contend with possible loss of surgical volume and revenues as well as decreased physician support and loyalty to the organization. Healthcare organizations can encourage physicians to remain in the organization by addressing physicians' concerns about the financial prospects and efficiency of independent and hospital-based ambulatory surgical arenas.

    Bayesian posterior parameter distributions are often simulated using Markov chain Monte Carlo (MCMC) methods. However, MCMC methods are not always necessary and do not help the uninitiated understand Bayesian inference. As a bridge to understanding Bayesian inference, the authors illustrate a transparent rejection sampling method. In example 1, they illustrate rejection sampling using 36 cases and 198 controls from a case-control study (1976-1983) assessing the relation between residential exposure to magnetic fields and the development of childhood cancer. Results from rejection sampling (odds ratio (OR) = 1.69, 95% posterior interval (PI): 0.57, 5.00) were similar to MCMC results (OR = 1.69, 95% PI: 0.58, 4.95) and approximations from data-augmentation priors (OR = 1.74, 95% PI: 0.60, 5.06). In example 2, the authors apply rejection sampling to a cohort study of 315 human immunodeficiency virus seroconverters (1984-1998) to assess the relation between viral load after infection and 5-year incidence of acquired immunodeficiency syndrome, adjusting for (continuous) age at seroconversion and race. In this more complex example, rejection sampling required a notably longer run time than MCMC sampling but remained feasible and again yielded similar results. The transparency of the proposed approach comes at a price of being less broadly applicable than MCMC.

    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.

    Enteral nutrition in the home of the patient, has gained interest in recent years. In our health care area, we do not have a Unit of at Home Hospitalization, which has not prevented the implementation of this therapeutic modality in certain types of patients. 89 cases who have undergone enteral Nutrition in their home after the last hospital admission, were reviewed. According to the basic pathology, 41.6% (37 patients) correspond to neurological patients; 51.7% correspond to neoplasmic patients, and 6.7% are classified as miscellaneous. The average age is 64 years (18 months-92 years); the mean caloric ingestion is 1,520 Kcal/day (500-2,500), and the duration is a mean of 315 days (7-1,560). The complications observed through ambulatory visits of the patient and/or the family, accounted for a total of 36, of which 30 (83%) were digestive, and were corrected with the usual methods. In 8 cases (22%), it involved mechanical complications, and only 2 cases involved metabolic complications. Only 1 serious complication (massive bronchoaspiration) could have been avoided. The results indicate a good degree of acceptance, with similar results to those described by other authors, and with a low incidence of severe complications.

    Little is known concerning the safety of the outpatient chemotherapy process. In the current study, the authors sought to identify medication error and potential adverse drug event (ADE) rates in the outpatient chemotherapy setting. A prospective cohort study of two adult and one pediatric outpatient chemotherapy infusion units at one cancer institute was performed, involving the review of orders for patients receiving medication and/or chemotherapy and chart reviews. The adult infusion units used a computerized order entry writing system, whereas the pediatric infusion unit used handwritten orders. Data were collected between March and December 2000. The authors reviewed 10,112 medication orders (8008 adult unit orders and 2104 pediatric unit orders) from 1606 patients (1380 adults and 226 pediatric patients). The medication error rate was 3% (306 of 10,112 orders). Of these errors, 82% occurring in adults (203 of 249 orders) had the potential for harm and were potential ADEs, compared with 60% of orders occurring in pediatric patients (34 of 57 orders). Among these, approximately one-third were potentially serious. Pharmacists and nurses intercepted 45% of potential ADEs before they reached the patient. Several changes were implemented in the adult and pediatric settings as a result of these findings. In the current study, the authors found an ambulatory medication error rate of 3%, including 2% of orders with the potential to cause harm. Although these rates are relatively low, there is clearly the potential for serious patient harm. The current study identified strategies for prevention.

    Gallbladder disease, with or without the formation of stones, can be treated in a number of ways. Conservative treatment of a low-fat diet may be difficult for the patient to maintain over a period of time, and may be ineffective in the long run. Chemodissolution of gallstones is a costly pharmacologic treatment that may require repeating within a 5-year period. Other forms of treatment include the still experimental shock wave lithotripsy to break up gallstones before chemodissolution therapy, or surgical removal of the gallbladder by traditional open laparotomy or by laparoscopic intervention. Laser laparoscopic cholecystectomy, a procedure suited to the ambulatory surgery setting, can be used for many individuals requiring cholecystectomy. It is less invasive than traditional surgery and results in a shorter hospital stay, less postoperative pain, and more rapid ambulation and recuperation. Most people can return to work in 3 days and can resume full physical activity after 1 week. Potential intraoperative complications include the puncture or rupture of a blood vessel or viscus with resulting hemorrhage or sepsis. Less serious complications in the postoperative time frame can include nausea and vomiting, minimal to moderate abdominal discomfort, and referred shoulder pain secondary to the pneumoperitoneum. A strong social support system is essential for the patient who is discharged to home within 4 to 23 hours after surgery.

    Adults with chronic disease are the most frequent users of the primary healthcare system. In Manitoba, patients are allowed to seek ambulatory (outpatient) care from the provider of their choosing (primary care physician or specialist), with referrals to specialists preferred but not always required. Some patients receive their routine care from specialists. We conducted this study to determine the patterns by which adults with chronic disease access ambulatory care as a prelude to exploring the impact these patterns may have on the quality of care received. Physician claims for all visits between 2007/8-2009/10 were extracted from the Data Repository at the Manitoba Centre for Health Policy. Patients included in the analysis made at least four ambulatory visits to a primary care physician or specialist within the study period, and met the definition criteria for at least one of six chronic diseases: diabetes mellitus; congestive heart failure; mood disorders; ischemic heart disease; total respiratory morbidity; and/or hypertension. Patients were "assigned" to the physician they visited most regularly. Physician visit patterns were assessed by dividing visits into nine visit types based on the type of physician patients visited (assigned primary care physician, other primary care physician, or specialist) and whether or not they received a referral. 347,606 patients with 7,662,411 physician visits were included in the analysis. Most visits were to the patients' assigned primary care physician. About 50% of the visits to specialists were by referral from the assigned primary care physician. However, 26-29% of all visits to a primary care physician were not to the assigned primary care physician, and non-assigned physicians were more likely to refer patients to specialists than assigned primary care physicians. The findings suggest that the current primary care system in Manitoba may not adequately support coordination of ambulatory care. Ambulatory visits to a

    It is assumed that more than 50% of the most enfeebling ocular diseases have their origin in the posterior segment. Furthermore, most of these diseases lead to partial or complete blindness, if left untreated. After cancer, blindness is the second most dreaded disease world over. However, treatment of posterior eye diseases is more challenging than the anterior segment ailments due to a series of anatomical barriers and physiological constraints confronted for delivery to this segment. In this regard, nanostructured drug delivery systems are proposed to defy ocular barriers, target retina, and act as permeation enhancers in addition to providing a controlled release. Since an important step towards developing effective treatment strategies is to understand the course or a route a drug molecule needs to follow to reach the target site, the first part of the present review discusses various pathways available for effective delivery to and clearance from the posterior eye. Promise held by nanocarrier systems, viz. liposomes, nanoparticles, and nanoemulsion, for effective delivery and selective targeting is also discussed with illustrative examples, tables, and flowcharts. However, the applicability of these nanocarrier systems as self-administration ocular drops is still an unrealized dream which is in itself a huge technological challenge.

We hypothesised that the discomfort during cuff inflation would increase the heart rate (HR measured with 24-h ambulatory BP monitoring compared to a following HR measurement with a 24-h Holter monitor.Methods: The study population (n = 56 were recruited from the outpatient’s clinic at the Department of Nephrology, Aalborg Hospital, Aarhus University Hospital at Aalborg, Denmark. All the patients had chronic kidney disease (CKD. We compared HR measured with a 24-h Holter monitor with a following HR measured by a 24-h ambulatory BP monitoring.Results: We found a highly significant correlation between the HR measured with the Holter monitor and HR measured with 24-h ambulatory blood pressure monitoring (r = 0.77, p < 0.001. Using the Bland-Altman plot, the mean difference in HR was only 0.5 beat/min during 24 hours with acceptable limits of agreement for both high and low HR levels. Dividing the patients into groups according to betablocker treatment, body mass index, age, sex, angiotensin-converting enzyme inhibitor treatment, statins treatment, diuretic treatment, or calcium channel blocker treatment revealed similar results as described above.Conclusion: The results indicate that the discomfort induced by cuff inflation during 24-h ambulatory BP monitoring does not increase HR. Thus, 24-h ambulatory BP monitoring may be a reliable measurement of the BP among people with CKD.Keywords: ambulatory blood pressure monitoring, Holter monitoring, heart rate, chronic kidney disease, hypertension

    Declining ambulatory activity represents an important facet of disablement in Parkinson disease (PD). The primary study aim was to compare the 2-year trajectory of ambulatory activity decline with concurrently evolving facets of disability in a small cohort of people with PD. The secondary aim was to identify baseline variables associated with ambulatory activity at 1- and 2-year follow-up assessments. This was a prospective, longitudinal cohort study. Seventeen people with PD (Hoehn and Yahr stages 1-3) were recruited from 2 outpatient settings. Ambulatory activity data were collected at baseline and at 1- and 2-year annual assessments. Motor, mood, balance, gait, upper extremity function, quality of life, self-efficacy, and levodopa equivalent daily dose data and data on activities of daily living also were collected. Participants displayed significant 1- and 2-year declines in the amount and intensity of ambulatory activity concurrently with increasing levodopa equivalent daily dose. Worsening motor symptoms and slowing of gait were apparent only after 2 years. Concurrent changes in the remaining clinical variables were not observed. Baseline ambulatory activity and physical performance variables had the strongest relationships with 1- and 2-year mean daily steps. The sample was small and homogeneous. Future research that combines ambulatory activity monitoring with a broader and more balanced array of measures would further illuminate the dynamic interactions among evolving facets of disablement and help determine the extent to which sustained patterns of recommended daily physical activity might slow the rate of disablement in PD. © 2015 American Physical Therapy Association.

    Familial dysautonomia (FD) is a rare genetic disease that involves extreme blood pressure fluctuations secondary to afferent baroreflex failure. The diurnal blood pressure profile, including the average, variability, and day-night difference, may have implications for long-term end organ damage. The purpose of this study was to describe the circadian pattern of blood pressure in the FD population and relationships with renal and pulmonary function, use of medications, and overall disability. We analyzed 24-h ambulatory blood pressure monitoring recordings in 22 patients with FD. Information about medications, disease severity, renal function (estimated glomerular filtration, eGFR), pulmonary function (forced expiratory volume in 1 s, FEV1) and an index of blood pressure variability (standard deviation of systolic pressure) were analyzed. The mean (± SEM) 24-h blood pressure was 115 ± 5.6/72 ± 2.0 mmHg. The diurnal blood pressure variability was high (daytime systolic pressure standard deviation 22.4 ± 1.5 mmHg, nighttime 17.2 ± 1.6), with a high frequency of a non-dipping pattern (16 patients, 73%). eGFR, use of medications, FEV1, and disability scores were unrelated to the degree of blood pressure variability or to dipping status. This FD cohort had normal average 24-h blood pressure, fluctuating blood pressure, and a high frequency of non-dippers. Although there was evidence of renal dysfunction based on eGFR and proteinuria, the ABPM profile was unrelated to the measures of end organ dysfunction or to reported disability.

    Few studies have examined ambulatory cardiovascular physiological parameters of taxi drivers while driving in relation to their occupational hazards. This study aims to investigate and quantify the impact of worksite physical hazards as a whole on ambulatory heart rate of professional taxi drivers while driving without their typical worksite psychosocial stressors. Ambulatory heart rate (HR driving ) of 13 non-smoking male taxi drivers (24 to 67 years old) while driving was continuously assessed on their 6-hour experimental on-road driving in Los Angeles. Percent maximum HR range (PMHR driving ) of the drivers while driving was estimated based on the individual HR driving values and US adult population resting HR (HR rest ) reference data. For analyses, the HR driving and PMHR driving data were split and averaged into 5-min segments. Five physical hazards inside taxi cabs were also monitored while driving. Work stress and work hours on typical work days were self-reported. The means of the ambulatory 5-min HR driving and PMHR driving values of the 13 drivers were 80.5 bpm (11.2 bpm higher than their mean HR rest ) and 10.7 % (range, 5.7 to 19.9 %), respectively. The means were lower than the upper limits of ambulatory HR and PMHR for a sustainable 8-hour work (35 bpm above HR rest and 30 % PMHR), although 15-27 % of the 5-min HR driving and PMHR driving values of one driver were higher than the limits. The levels of the five physical hazards among the drivers were modest: temperature (26.4 ± 3.0 °C), relative humidity (40.7 ± 10.4 %), PM 2.5 (21.5 ± 7.9  μg /m 3 ), CO 2 (1,267.1 ± 580.0 ppm) and noise (69.7 ± 3.0 dBA). The drivers worked, on average, 72 h per week and more than half of them reported that their job were often stressful. The impact of physical worksite hazards alone on ambulatory HR of professional taxi drivers in Los Angeles generally appeared to be minor. Future ambulatory heart rate studies including both

The most common location is at the occipital bone, and its incidence varies according to different world regions. We report a case of an 1-month and 7-day-old male child with a huge interparietal-posterior fontanel meningohydroencephalocele, a rare occurrence. Physical examination and volumetric computed tomography were diagnostic. The encephalocele was surgically resected. Intradural and extradural approaches were performed; the bone defect was not primarily closed. Two days after surgery, the patient developed hydrocephaly requiring ventriculoperitoneal shunting. The surgical treatment of the meningohydroencephalocele of the interparietal-posterior fontanel may be accompanied by technical challenges and followed by complications due to the presence of large blood vessels under the overlying skin. In these cases, huge sacs herniate through large bone defects including meninges, brain, and blood vessels. The latter present communication with the superior sagittal sinus and ventricular system. A favorable surgical outcome generally follows an accurate strategy taking into account individual features of the lesion.

    Johnson, Philip K; Ferguson, Michael A; Zachariah, Justin P

    2016-07-01

    Since younger patients have low pretest probability of hypertension and are susceptible to reactive and masked hypertension, ambulatory blood pressure monitoring (ABPM) can be useful. To better target use in referred patients, we sought to define in-clinic systolic blood pressure (SBP) measures that predicted normal ABPM and target end organ damage. Data were collected on consecutive patients referred for high BP undergoing an ambulatory BP monitor from 2010 to 2013 (n = 248, 33.9% female, mean age 15.5 ± 3.6 years). Candidate in-clinic predictors were systolic maximum, minimum, or average BPs obtained by auscultative, oscillometric, or both. Multivariable logistic regression models were used to determine the prediction of normal ABPM by in-clinic BP predictors. Separate models considered predicting left ventricular hypertrophy (LVH) by in-clinic SBP vs. ABPM-defined hypertension. Identified predictor utility was tested with receiver operator characteristic curves. Maximum (OR 0.97 [95% CI 0.94-0.99]; P = .047), minimum (0.96 [0.94-0.99]; P = .002), and average (0.97 [0.95-1.00]; P = .04) in-clinic auscultative SBP predicted normal ABPM. Each had a c-statistic of 0.58. LVH was associated with in-clinic auscultative minimum SBP treated continuously (1.05, [1.01-1.10], P = .01) or dichotomized at the 90th percentile (8.23, [1.48-45.80], P = .02), as well as ABPM-defined hypertension (3.31, [1.23-8.91], P = .02). Both predictors had poor sensitivity and specificity. In youth, normal auscultative in-clinic systolic blood pressure indices weakly predicted normal ambulatory blood pressure and target end organ damage. © 2016 Wiley Periodicals, Inc.

    We examined the ambulatory health care visit use of children with spina bifida, adults who transitioned to adult care and adults who continued to seek care in a pediatric setting. We evaluated use during a 1-year period of patients with spina bifida who visited any outpatient medical clinic within an integrated health care system. Patients were categorized as pediatric (younger than 18 years) or adult (age 18 or older). Adults were divided into those who did not fully transition to adult care and patients who fully transitioned (adult). Frequency and type of health care use were compared. Subanalysis was performed for patients 18 to 25 years old to examine variables associated with successful complete transition to adult care. During 1 year 382 children, 88 patients who did not transition and 293 adult patients with spina bifida had 4,931 clinic visits. Children had greater ambulatory care use (7.25 visits per year) compared to fully transitioned adults (5.33 visits per year, p=0.046). Children more commonly visited surgical clinics (52.3% of visits) and adults more commonly visited medical clinics (48.9%) (p spina bifida used more ambulatory care than adults and were more likely to visit a surgical specialist. Adult patients with spina bifida who successfully transitioned to adult care were more likely to be female, and patients who failed to transition were more likely to receive more inpatient and emergency care.

  19. [Judet posterior approach to the scapula].

    Science.gov (United States)

    Bartonícek, J; Tucek, M; Lunácek, L

    2008-12-01

    A detailed description of the Judet posterior approach to the scapula. The authors used this approach in 24 patients operated on for fractures of the scapular body and neck and for combined fractures of the scapula. In 23 patients the surgical site healed without complications, in 1 case revision was required due to a haematoma. DESCRIPTION OF THE APPROACH: The approach has three phases. The first of them consists in a boomerang skin incision along the scapular spine and the medial scapular border producing a skin flap, and identification of the posterior border of the deltoid. In the next phase, the posterior deltoid is dissected off the scapular spine and reflected laterally. In the final phase, the infraspinatus is mobilized and reflected proximally. During the whole procedure the neurovascular bundle passing from the spinoglenoid notch to the infraspinatus must be handled with maximum caution. In certain types of fractures of the scapula, this approach may be limited using a medial and a lateral window to expose the respective borders of the scapular body, without full mobilization of the infraspinatus. On the other hand, where the fracture of the scapula is associated with a fracture of the lateral clavicle or dislocation of the AC joint, the approach may be extended using a saber cut incision starting from the proximolateral angle of the Judet incision and passing over the AC joint. This modification was used in a fracture of the scapular body associated with dislocation of the AC joint. The advantage of the Judet approach is an excellent exposure of the infraspinousus fossa. The main disadvantage of this approach is considered its extensiveness and atrophy of the infraspinatus that is most probably caused by its mobilization. However, there may be more causes of this atrophy. The first of them is injury to the suprascapular nerve in fractures of the surgical neck of the scapula by its entrapment in the fracture line. In these fractures the whole course of

    Thoracic ossification of the posterior longitudinal ligament (T-OPLL) is treated surgically with instrumented posterior decompression and fusion. However, the factors determining the outcome of this approach and the efficacy of additional resection of T-OPLL are unknown. To identify these factors in a prospective study at a single institution. The subjects were 70 consecutive patients with beak-type T-OPLL who underwent posterior decompression and dekyphotic fusion and had an average of 4.8 years of follow-up (minimum of 2 years). Of these patients, 4 (6%; group R) had no improvement or aggravation, were not ambulatory for 3 weeks postoperatively, and required additional T-OPLL resection; while 66 (group N) required no further T-OPLL resection. Clinical records, gait status, intraoperative ultrasonography, intraoperative neurophysiological monitoring (IONM), plain radiography, computed tomography and magnetic resonance imaging findings, and Japanese Orthopaedic Association (JOA) score were compared between the groups. Preoperatively, patients in group R had significantly higher rates of severe motor paralysis, nonambulatory status, positive prone and supine position test, no spinal cord floating in intraoperative ultrasonography, and deterioration of IONM at the end of surgery ( P < .05). In preoperative radiography, the OPLL spinal cord kyphotic angle difference in fused area, OPLL length, and OPLL canal stenosis were significantly higher in group R ( P < .05). At final follow-up, JOA scores improved similarly in both groups. Preoperative severe motor paralysis, nonambulatory status, positive prone and supine position test, radiographic spinal cord compression due to beak-type T-OPLL, and intraoperative residual spinal cord compression and deterioration of IONM were associated with ineffectiveness of posterior decompression and fusion with instrumentation. Our 2-stage strategy may be appropriate for beak-type T-OPLL surgery. Copyright © 2017 by the Congress of

Descriptive and comparative study of the Ambulatory Care Index (AI) and Substitution Index (SI) in the Santa Cristina Hospital Surgery Service (Madrid, Spain) compared to Key Indicators (KI) of the National Health Service (NHS). 7,817 MAS procedures (between 2006 and 2014) were analysed. The average annual AI was 54%, higher (p <0.0001) than «ambulatory surgery» KI. The hernia outpatient procedures (average 72%) were also superior to the national KI (p <0.0001), but ambulatory haemorrhoidectomy (average 33.6%) was clearly lower (p <0.0001). KI of the NHS are useful and allow to establish a proper development in the global AI and hernia outpatient surgery with opportunities for improvement in haemorrhoidectomy. Their collection should be careful, not including minor surgeries. Also, their usefulness could be increased if data was broken down by speciality and by complexity. Copyright © 2017 SESPAS.

  13. Ambulatory Blood Pressure Monitoring in Clinical Practice: A Review

    Science.gov (United States)

    Viera, Anthony J.; Shimbo, Daichi

    2016-01-01

    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.

    2018-02-01

    Objectives Wait lists are common in ambulatory and community-based services. The aim of the present study was to explore managers' perceptions of factors that contribute to wait times. Methods A qualitative study was conducted using semi-structured interviews with managers and team leaders of ambulatory and community health services within a large health network. Interviews were transcribed and coded, and the codes were then grouped into themes and subthemes. Results Representatives from 26 services participated in the project. Four major themes were identified. Three themes related to reasons and factors contributing to increased wait time for services (inefficient intake and scheduling processes; service disruptions due to human resource issues; and high service demand). A fourth theme related to staff attitudes towards wait times and acceptance and acknowledgement of wait lists. Conclusions Service providers perceive high demand to be a key driver of wait times, but a range of other factors also contributes and may represent opportunities for improving access to care. These other factors include improving process efficiencies, greater consistency of service delivery through more efficient management of human resources and shifting to more consumer-centred approaches in measuring wait times in order to drive improvements in patient flow. What is known about the topic? Wait times are common in out-patient and ambulatory services. These services experience high demand, which is likely to continue to grow as health service delivery shifts from hospital to community settings. What does this paper add? Although demand is an important driver of wait times, there are other modifiable factors that also contribute, including process inefficiencies and service disruption related to human resource issues. An underlying staff attitude of acceptance of wait times appears to be an additional barrier to improving access. What are the implications for practitioners? The findings

    Full Text Available Replacement of missing teeth in the posterior maxilla is always a challenge for the treating implant surgeon as the posterior maxilla has several obstacles in the form of quality, quantity, the anatomy of the maxillary sinus, and inaccessibility. To overcome these deficiencies, several surgical procedures such as sinus lift, bone augmentation, tilted implants, short implants, and zygomatic implants were tried. Since these procedures have their own limitations, pterygomaxillary region provides us an excellent place for placement of implant and rehabilitation of posterior maxilla. This case report describes the usage of the pterygomaxillary region for placement of the implant to restore atrophic posterior maxilla, without any additional surgical procedures.

  17. Clinical value of ambulatory blood pressure: evidence and limits.

    Science.gov (United States)

    Mancia, Giuseppe; Verdecchia, Paolo

    2015-03-13

    This article reviews the clinical value of ambulatory blood pressure (BP) vis-à-vis the traditional BP measurements taken in the physician's office or in the hospital. Mention is initially made that longitudinal studies conducted in the general population or in hypertensive cohorts have shown that ambulatory BP provides a more accurate prediction of outcome than office BP. Namely, that (1) the risk of cardiovascular events increases in a less steep fashion with office than with 24-hour mean BP, (2) the 24-hour BP-dependent prediction is maintained after adjustment for office BP values, and (3) among individuals with normal office BP, those with increased ambulatory BP (masked hypertension) have an increased prevalence of organ damage, a more frequent unfavorable metabolic profile and a higher risk of new onset sustained hypertension, diabetes mellitus, and cardiovascular events than those with normal ambulatory BP. It is further mentioned, however, that more recently similar observations have been made for individuals with high office but normal ambulatory BP (white coat hypertension) suggesting a complementary role of out-of-office and office BP values in the determination of patients' prognosis. The evidence in favor of an independent prognostic value also of some within 24-hour BP phenomena (night BP reduction or absolute values, short-term BP variations, and morning BP surge) is then critically appraised for its elements of strength and weakness. Finally, whether the clinical advantages of ambulatory BP make this approach necessary for all patients with hypertension is discussed. The conclusion is that this is at present still premature because crucial evidence pro or against routine use of this approach in untreated and treated hypertensives is not yet available. It will be crucial for future studies to determine whether, compared with a treatment guided by office BP, a treatment tailored on ambulatory BP allows to improve prevention or regression of organ

    The variability of blood pressure (BP) makes any single measurement a poor indicator of a patient's true BP. Multiple studies have confirmed the superiority of ambulatory BP measurements over clinic BP measurements in predicting cardiovascular risk; however, this method presents the problem of patient acceptance as it causes frequent arm discomfort and sleep disturbance. We hypothesized that 6 h of daytime BP measurements would result in slightly higher BP readings, yet reveal similar clinical decision making when compared to 24 h of BP measurements. The source for writing this article was a retrospective analysis of 30 patients who underwent ambulatory BP monitoring. Data obtained included: age, sex, ethnicity, baseline medical problems, medications, laboratory values, reason given for ordering 24-h ambulatory BP measurements, ambulatory BP measurements, and a subsequent decision to change medication. The average BP of the 24-h measurements was 127/75 mm Hg and the average BP of the 6-h daytime measurements was 131/79 mm Hg (SD 15, p = 0.009). Twenty-six out of 30 patients were at goal or pre-hypertensive. Two out of 30 patients had stage 1 hypertension and 2 out of 30 patients had stage 2 hypertension. Thirteen out of 30 patients had nocturnal dipping. Twelve out of 30 patients had a change in medication, but those changes were not associated with the presence or absence of nocturnal dipping (p = 0.5) or other factors beyond mean BP. Although there was a statistically significant, 4 mm Hg systolic difference between 24-h and 6-h average BP readings, there was no evidence that this difference led to changes in clinical management. The presence or absence of nocturnal dipping was not associated with a change in medication. We conclude that 6-h daytime ambulatory BP measurements provide sufficient information to guide clinical decision making without the problems of patient acceptance, arm discomfort, and sleep disturbance associated with 24-h BP measurements.

    Full Text Available Susan Dabu-Bondoc, Kirk Shelley Department of Anesthesiology, School of Medicine, Yale University, New Haven, CT, USAAbstract: Advances in medical science now allow people with significant medical issues to live at home. As the outpatient population ages and surgical techniques advance, the ambulatory anesthesiologist has to be prepared to handle these “walking wounded”. The days of restricting ambulatory surgery procedures to American Society of Anesthesiologists class 1 and 2 patients are rapidly fading into the past. To remain competitive and economically viable, the modern ambulatory surgery center needs to expand its practice to include patients with medical comorbidities. In an environment where production and economic pressures exist, maintaining safety and good outcomes in high-risk patients for ambulatory surgery can be arduous. Adding to the complexity of this challenge is the rapid evolution of the therapeutic approaches to a variety of medical issues. For example, there has been a significant increase in the number and types of insulin a diabetic patient might be prescribed in recent years. In the case of the patient with coronary artery disease, the variety of both drug and nondrug eluding stents or new antithrombotic agents has also increased the complexity of perioperative management. Complex patients need careful, timely, and team-based preoperative evaluation by an anesthesia provider who is knowledgeable of outpatient care. Optimizing comorbidities preoperatively is a crucial initial step in minimizing risk. This paper will examine a number of common medical issues and explore their impact on managing outpatient surgical procedures.Keywords: ambulatory surgery, medical comorbidities, diabetes, coronary artery disease, respiratory disease, obesity

    Full Text Available Obstructive sleep apnoea (OSA is a highly prevalent disorder associated with complications such as arterial hypertension, cardiovascular diseases and traffic accidents. The resources allocated for OSA are insufficient and OSA is a significant public health problem. Portable recording devices have been developed for the detection of OSA syndrome and have proved capable of providing an equivalent diagnosis to in-laboratory polysomnography (PSG, at least in patients with a high pre-test probability of OSA syndrome. PSG becomes important in patients who have symptoms and certain comorbidities such as chronic obstructive pulmonary disease or stroke, as well as in patients with a clinical history suggesting a different sleep disorder. Continuous positive airway pressure is the most effective treatment in OSA. Ambulatory monitoring of the therapeutic modalities has been evaluated to enhance the care process and reduce costs compared to the conventional approach, without sacrificing efficiency. This review evaluates the role of portable monitoring devices in the diagnostic process of OSA and the search for alternative strategies based on ambulatory management protocols.

    Full Text Available Interest in the effects of sleeping behavior on health and performance is continuously increasing-both in research and with the general public. Ecologically valid investigations of this research topic necessitate the measurement of sleep within people's natural living contexts. We present evidence that a new approach for ambulatory accelerometry data offers a convenient, reliable, and valid measurement of both people's sleeping duration and quality in their natural environment. Ninety-two participants (14-83 years wore acceleration sensors on the sternum and right thigh while spending the night in their natural environment and following their normal routine. Physical activity, body posture, and change in body posture during the night were classified using a newly developed classification algorithm based on angular changes of body axes. The duration of supine posture and objective indicators of sleep quality showed convergent validity with self-reports of sleep duration and quality as well as external validity regarding expected age differences. The algorithms for classifying sleep postures and posture changes very reliably distinguished postures with 99.7% accuracy. We conclude that the new algorithm based on body posture classification using ambulatory accelerometry data offers a feasible and ecologically valid approach to monitor sleeping behavior in sizable and heterogeneous samples at home.

    Full Text Available Zakaria Messieha Department of Anesthesiology, University of Illinois at Chicago, Chicago, IL, USA Abstract: Ambulatory surgical and anesthesia care (ASAC, also known as Same Day Surgery or Day Care in some countries, is the fastest growing segment of ambulatory surgical and anesthesia care. Over 50 million ambulatory surgical procedures are conducted annually comprising over 60% of all anesthesia care with an impressive track record of safety and efficiency. Advances in ambulatory anesthesia care have been due to newer generation of inhalation and intravenous anesthetics as well as airway management technology and techniques. Successful ambulatory anesthesia care relies on patient selection, adequate facilities, highly trained personnel and quality improvement policies and procedures. Favoring one anesthetic technique over the other should be patient and procedure-specific. Effective management of post-operative pain as well as nausea and vomiting are the final pieces in assuring success in ambulatory anesthesia care.

    Posterior urethra primary realignment (PUPR) after complete transection may decrease the gap between the ends of the transected urethra, tamponade the retropubic bleeding, and optimize urinary drainage without the need of suprapubic catheter facilitating concurrent pelvic orthopedic and trauma procedures. Historically, the distorted anatomy after pelvic trauma has been a major surgical challenge. The purpose of the study was to assess the relationship of the severity of the pelvic fracture to the success of endoscopic and immediate PUPR following complete posterior urethral disruption using the Young-Burgess classification system. A review of our Level I trauma center database for patients diagnosed with pelvic fracture and complete posterior urethral disruption from January 2005 to April 2012 was performed. Pelvic fracture severity was categorized according to the Young-Burgees classification system. Management consisted of suprapubic catheter insertion at diagnosis followed by early urethral realignment when the patient was clinically stable. Failure of realignment was defined as inability to achieve urethral continuity with Foley catheterization. Clinical follow-up consisted of radiologic, pressure studies and cystoscopic evaluation. A total of 481 patients with pelvic trauma from our trauma registry were screened initially, and 18 (3.7%) were diagnosed with a complete posterior urethral disruption. A total of 15 primary realignments (83.3%) were performed all within 5 days of trauma. The success rate of early realignment was 100%. There was no correlation between the type of pelvic ring fracture and the success of PUPR. Postoperatively, 8 patients (53.3%) developed urethral strictures, 3 patients (20.0%) developed incontinence, and 7 patients (46.7%) reported erectile dysfunction after the trauma. The mean follow-up of these patients was 31.8 months. Endoscopic PUPR may be an effective option for the treatment of complete posterior urethral disruption and

    Micro-instability (non-radiographic clinical instability) continues to gain recognition as a problem at the hip. Although most research has been directed to anterior hip instability, posterior hip instability (PHI) has also garnered attention. PHI is under recognized, difficult to identify, and confused with other hip pathologies such as a simple sprain or strain. A novel clinical test is introduced that may have helped identify PHI in this patient. Additionally, a conservative rehabilitation approach emphasizing stabilization exercises is described. A 29-year-old female presented with complaints of posterior lateral and anterior hip pain of 1.5 years duration. Upon initiating an aggressive stretching program, her pain worsened. Examination revealed limited and painful hip flexion, and positive anterior impingement testing for femoroacetabular impingement. Both tests were significantly less painful with more motion when retested with manual repositioning of the femoral head from posterior to anterior, referred to as posterior relocation testing. The patient was instructed to discontinue stretching. A stabilization plan was established including strengthening of the deep external rotators with trunk and lower quarter neuromuscular re-education. The patient completed 12 appointments over 2.5 months. At discharge, the patient reported improvements with pain and function. The Lower Extremity Functional Scale improved from 64/80 to 77/80 and Oswestry Disability Questionnaire improved from 8 to 0%. PHI may have contributed to this patient's symptoms. The posterior relocation test may assist clinicians with identification of PHI, thus directing treatment toward stabilization and neuromuscular control rather than interventions designed to increase mobility. 4.

    The authors describe the use of autogenetic posterior atlantooccipital (PAO) membrane for duraplasty following after posterior cranial fossa surgery. The PAO membrane is routinely exposed for procedures of the posterior cranial fossa and merely needs to be dissected free of the underlying dura mater. Recently this membrane was obtained in several pediatric patients following procedures of the posterior cranial fossa such as duraplasty in case of Chiari I malformation. No postoperative complications were found at 6-month follow-up examination. The advantages of this intervention include less manipulation of muscle and fascia than that involved in other procedures and, therefore, seemingly less postoperative pain and the negation of issues inherent with foreign-body graft sources. The authors believe this structure to be of use as a dural substitute in small dural openings of the posterior cranial fossa.

  10. Can abdominal surgical emergencies be treated in an ambulatory setting?

    2015-12-01

    The performance of emergency abdominal surgery in an outpatient setting is increasingly the order of the day in France. This review evaluates the feasibility and reliability of ambulatory surgical treatment of the most common abdominal emergencies: appendectomy for acute appendicitis and cholecystectomy for acute complications of gallstone disease (acute cholecystitis and gallstone pancreatitis). This study evaluates surgical procedures performed on an ambulatory basis according to the international definition (admission in the morning, discharge in the evening with a hospital stay of less than 12 hours). Just as for elective surgery, eligibility of patients for an ambulatory approach depends on the capacities of the surgical and anesthesia team: to manage the risks, particularly the risk of deferring surgery until the morning); to prevent or treat post-operative symptoms like pain, nausea, vomiting, re-ambulation in order to permit rapid post-operative discharge. Recent studies have shown that appendectomy for non-complicated acute appendicitis can be deferred for up to 12 hours without any increase in danger. Many other studies have shown that early discharge after appendectomy for acute non-complicated appendicitis is feasible and safe. Nonetheless, there is only one published series of truly ambulatory appendectomies. The results were excellent. Patients who presented in the afternoon were brought back for operation the following morning. The appropriate timing for performance of cholecystectomy in patients with acute calculous cholecystitis or gallstone pancreatitis has not been well defined, but is always somewhat delayed relative to the onset of symptoms. To minimize operative complications, cholecystectomy for acute calculous cholecystitis should probably be performed between 24 and 72 hours after diagnosis. Cholecystectomy for gallstone pancreatitis should probably not be delayed longer than a week; the need to keep the patient hospitalized during the

    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. 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. 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. 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. Chronic ambulatory ECoG in patients with suspected

    Bladder hyperactivity is described as the presence of "voiding urgency, generally associated with increased daytime frequency and nocturia, with or without urinary incontinence, in the absence of urinary tract infection or other obvious pathology". Onabotulinum toxin A (BTA) is a recommendable therapeutic option in case of failure, contraindication or refusal of the conservative therapy or other non-pharmacological therapies. The injection of BTA in the detrusor has been performed under local, regional or general anesthesia either in the conventional or major ambulatory surgery operative room or in the cystoscopy room. The objective of this paper is to describe the procedure to perform BTA therapy as an ambulatory operation under intravesical local anesthesia in the cystoscopy room, describing its advantages and limitations.

    The classification of posterior fossa congenital anomalies has been a controversial topic. Advances in genetics and imaging have allowed a better understanding of the embryologic development of these abnormalities. A new classification schema correlates the embryologic, morphologic, and genetic bases of these anomalies in order to better distinguish and describe them. Although they provide a better understanding of the clinical aspects and genetics of these disorders, it is crucial for the radiologist to be able to diagnose the congenital posterior fossa anomalies based on their morphology, since neuroimaging is usually the initial step when these disorders are suspected. We divide the most common posterior fossa congenital anomalies into two groups: 1) hindbrain malformations, including diseases with cerebellar or vermian agenesis, aplasia or hypoplasia and cystic posterior fossa anomalies; and 2) cranial vault malformations. In addition, we will review the embryologic development of the posterior fossa and, from the perspective of embryonic development, will describe the imaging appearance of congenital posterior fossa anomalies. Knowledge of the developmental bases of these malformations facilitates detection of the morphological changes identified on imaging, allowing accurate differentiation and diagnosis of congenital posterior fossa anomalies.

    Posterior fossa ependymoma comprises two distinct molecular entities, ependymoma_posterior fossa A (EPN_PFA) and ependymoma_posterior fossa B (EPN_PFB), with differentiable gene expression profiles. As yet, the response of the two entities to treatment is unclear. To determine the relationship between the two molecular subgroups of posterior fossa ependymoma and treatment, we studied a cohort of 820 patients with molecularly profiled, clinically annotated posterior fossa ependymomas. We found that the strongest predictor of poor outcome in patients with posterior fossa ependymoma across the entire age spectrum was molecular subgroup EPN_PFA, which was recently reported in the paper entitled "Therapeutic impact of cytoreductive surgery and irradiation of posterior fossa ependymoma in the molecular era: a retrospective multicohort analysis" in the Journal of Clinical Oncology. Patients with incompletely resected EPN_PFA tumors had a very poor outcome despite receiving adjuvant radiation therapy, whereas a substantial proportion of patients with EPN_PFB tumors can be cured with surgery alone.

    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.

    The ambulatory physician payment system in the German Social Health Insurance (SHI) offers incentives to reduce practice activity at the end of a billing period. Most services within a period are reimbursed at full cost only up to a certain threshold. Furthermore, capitated payments make follow-up treatments within a billing period less profitable.

  19. Redesigning ambulatory care business processes supporting clinical care delivery.

    Patterson, C; Sinkewich, M; Short, J; Callas, E

    1997-04-01

    The first step in redesigning the health care delivery process for ambulatory care begins with the patient and the business processes that support the patient. Patient-related business processes include patient access, service documentation, billing, follow-up, collection, and payment. Access is the portal to the clinical delivery and care management process. Service documentation, charge capture, and payment and collection are supporting processes to care delivery. Realigned provider networks now demand realigned patient business services to provide their members/customers/patients with improved service delivery at less cost. Purchaser mandates for cost containment, health maintenance, and enhanced quality of care have created an environment where every aspect of the delivery system, especially ambulatory care, is being judged. Business processes supporting the outpatient are therefore being reexamined for better efficiency and customer satisfaction. Many health care systems have made major investments in their ambulatory care environment, but have pursued traditional supporting business practices--such as multiple access points, lack of integrated patient appointment scheduling and registration, and multiple patient bills. These are areas that are appropriate for redesign efforts--all with the customer's needs and convenience in mind. Similarly, setting unrealistic expectations, underestimating the effort required, and ignoring the human elements of a patient-focused business service redesign effort can sabotage the very sound reasons for executing such an endeavor. Pitfalls can be avoided if a structured methodology, coupled with a change management process, are employed. Deloitte & Touche Consulting Group has been involved in several major efforts, all with ambulatory care settings to assist with the redesign of their business practices to consider the patient as the driver, instead of the institution providing the care.

    Chlamydia trachomatis (CT) is the most commonly reported sexually transmitted infection (STI) in the US and timely, correct treatment can reduce CT transmission and sequelae. Emergency departments (ED) are an important location for diagnosing STIs. This study compared recommended treatment of CT in EDs to treatment in physician offices. Five years of data (2006-2010) were analyzed from the National Ambulatory Medical Care Survey, and the National Hospital Ambulatory Medical Care Surveys (NHAMCS), including the Outpatient survey (NHAMCS-OPD) and Emergency Department survey (NHAMCS-ED). All visits with a CT diagnosis and those with a diagnosis of unspecified venereal disease were selected for analysis. Differences in receipt of recommended treatments were compared between visits to physician offices and emergency departments using Chi square tests and logistic regression models. During the 5 year period, approximately 3.2 million ambulatory care visits had diagnosed CT or an unspecified venereal disease. A greater proportion of visits to EDs received the recommended treatment for CT compared to visits to physician offices (66.1 vs. 44.9 %, p < .01). When controlling for patients' age, sex and race/ethnicity, those presenting to the ED with CT were more likely to receive the recommended antibiotic treatment than patients presenting to a physician's office (OR 2.16; 95 % CI 1.04-4.48). This effect was attenuated when further controlling for patients' expected source of payment. These analyses demonstrate differences in the treatment of CT by ambulatory care setting as well as opportunities for increasing use of recommended treatments for diagnosed cases of this important STI.

    Efforts to measure quality of care do not capture the unique aspects of ambulatory oncology settings. To retain nurses, ensure a safe practice environment, and encourage behaviors that support high-quality care, there is a need to identify factors associated with job satisfaction and turnover with measures that reflect the ambulatory setting. The objective of this study was to examine the patterns and correlates of the work environment for nurses and nurse practitioners working in a National Cancer Institute-designated Comprehensive Cancer Center. Web-based questionnaires were disseminated to employees with a registered nurse license in ambulatory settings and related support services and included 3 affiliated satellite locations. Participants completed the Practice Environment Scale of the Nursing Work Index, revised for ambulatory oncology settings, the Safety Organizing Scale, and items to assess job satisfaction, perceived quality of care, and intention to leave their current position. Logistic and linear regression models were used to examine factors associated with these outcomes. From 403 individuals, 319 (79.2%) participated. The majority of respondents endorsed excellent quality of care (57.7%), job satisfaction (69.3%), and intention to stay in current position (77.4%). Endorsement of favorable collegial nurse-physician relationships was significantly associated with all 3 outcomes and increased performance of safety organizing behaviors. Nurses reported variations in practice environments and safety organizing behaviors across units. Work environment assessments are useful to retain experienced nurses and support the delivery of high-quality patient care. Routine assessment of the work environment for registered nurses and advanced practice nurses is feasible and informative.

    Full Text Available Chong Han Pek,1 John Tey,2 Ern Yu Tan1 1Department of General Surgery, 2Department of Anaesthesiology, Intensive Care and Pain Medicine, Tan Tock Seng Hospital, Singapore, Singapore Abstract: Ambulatory breast cancer surgery is well accepted and is the standard of care at many tertiary centers. Rather than being hospitalized after surgery, patients are discharged on the day of surgery or within 23 hours. Such early discharge does not adversely affect patient outcomes and has the added benefits of better psychological adjustment for the patient, economic savings, and a more efficient utilization of health care resources. The minimal care needed post-discharge also means that the caregiver is not unduly burdened. Unplanned conversions to inpatient admission and readmission rates are low. Wound complications are infrequent and no issues with drain care have been reported. Because the period of postoperative observation is short and monitoring is not as intensive, ambulatory surgery is only suitable for low-risk procedures such as breast cancer surgery and in patients without serious comorbidities, where the likelihood of major perioperative events is low. Optimal management of pain, nausea, and vomiting is essential to ensure a quick recovery and return to normal function. Regional anesthesia such as the thoracic paravertebral block has been employed to improve pain control during the surgery and in the immediate postoperative period. The block provides excellent pain relief and reduces the need for opiates, which also consequently reduces the incidence of nausea and vomiting. The increasing popularity of total intravenous anesthesia with propofol has also helped reduce the incidence of nausea and vomiting in the postoperative period. Ambulatory surgery can be safely carried out in centers where there is a well-designed workflow to ensure proper patient selection, counseling, and education, and where patients and caregivers have easy access to

    Full Text Available Objective To retrospectively analyze effective methods for surgical management of posterior circulation aneurysms. Methods There were 42 patients with posterior circulation aneurysms [26 cases of basilar aneurysm (27 aneurysms, 16 cases of vertebral aneurysm (17 aneurysms]. There were 15 patients underwent bypass surgery [4 external carotid artery-P2 segment of posterior cerebral artery (ECA-P2, 2 internal carotid artery-P2 segment of posterior cerebral artery (ICA-P2, 2 internal maxillary artery-P2 segment of posterior cerebral artery (IMA-P2, 2 intracranial segment of vertebral artery-extracranial segment of vertebral artery, 5 occipital artery-posterior inferior cerebellar artery (OA-PICA] and 27 patients underwent simple surgical clipping. Results Activities of daily life of 37 patients recovered to normal (14 patients with aneurysm on the top of basilar artery, 3 with aneurysm on the trunk of basilar artery, 9 with vertebral aneurysm, 5 with posterior inferior cerebellar artery aneurysm, 4 with aneurysm on the junction of P1-P2 segment of posterior cerebral artery, 1 with superior cerebellar artery, and 1 with anterior inferior cerebellar aneurysm. None of them occurred operation-related neurological dysfunction. The recovery rate was 88.09% . Among the other patients, 1 with aneurysm on the top of basilar artery presented severe signs and symptoms of neurological defect and cannot take care of oneself, 2 patients (1 with aneurysm on the top of basilar artery, 1 with aneurysm on the trunk of basilar artery occurred brain stem hemorrhage after operation, and died at perioperative period, 2 with vertebral aneurysm relapsed and was cured after treatment. Conclusion Posterior circulation aneurysm which is not suitable for surgical clipping can be treated with intra? and extra?cranial vessel bypass. It may avoid the risk of surgical clipping of aneurysm.

    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.

    To examine trends in melanoma visits in the ambulatory care setting. Methods. Data from the National Ambulatory Medical Care Survey (NAMCS) from 1979 to 2010 were used to analyze melanoma visit characteristics including number of visits, age and gender of patients, and physician specialty. These data were compared to US Census population estimates during the same time period. Results. The overall rate of melanoma visits increased (ρ< 0.0001) at an apparently higher rate than the increase in population over this time. The age of patients with melanoma visits increased at approximately double the rate (0.47 year per interval year, ρ< 0.0001) of the population increase in age (0.23 year per interval year). There was a nonsignificant(ρ=0.19) decline in the proportion of female patients seen over the study interval. Lastly, ambulatory care has shifted towards dermatologists and other specialties managing melanoma patients and away from family/internal medicine physicians and general/plastic surgeons. Conclusions. The number and age of melanoma visits has increased over time with respect to the overall population, mirroring the increase in melanoma incidence over the past three decades. These trends highlight the need for further studies regarding melanoma management efficiency

    There is a growing need for patient education and an evaluation of its outcomes. The aim of this study was to compare ambulatory orthopaedic surgery patients' knowledge with Internet-based education and face-to-face education with a nurse. The following hypothesis was proposed: Internet-based patient education (experiment) is as effective as face-to-face education with a nurse (control) in increasing patients' level of knowledge and sufficiency of knowledge. In addition, the correlations of demographic variables were tested. The patients were randomized to either an experiment group (n = 72) or a control group (n = 75). Empirical data were collected with two instruments. Patients in both groups showed improvement in their knowledge during their care. Patients in the experiment group improved their knowledge level significantly more in total than those patients in the control group. There were no differences in patients' sufficiency of knowledge between the groups. Knowledge was correlated especially with patients' age, gender and earlier ambulatory surgeries. As a conclusion, positive results concerning patients' knowledge could be achieved with the Internet-based education. The Internet is a viable method in ambulatory care.

    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.

  10. The demand for ambulatory mental health services from specialty providers.

    1986-01-01

    A two-part model is used to examine the demand for ambulatory mental health services in the specialty sector. In the first equation, the probability of having a mental health visit is estimated. In the second part of the model, variations in levels of use expressed in terms of visits and expenditures are examined in turn, with each of these equations conditional on positive utilization of mental health services. In the second part of the model, users are additionally grouped into those with and without out-of-pocket payment for services. This specification accounts for special characteristics regarding the utilization of ambulatory mental health services: (1) a large part of the population does not use these services; (2) of those who use services, the distribution of use is highly skewed; and (3) a large number of users have zero out-of-pocket expenditures. Cost-sharing does indeed matter in the demand for ambulatory mental health services from specialty providers; however, the decision to use mental health services is affected by the level of cost-sharing to a lesser degree than is the decision regarding the level of use of services. The results also show that price is only one of several important factors in determining the demand for services. The lack of significance of family income and of being female is notable. Evidence is presented for the existence of bandwagon effects. The importance of Medicaid in the probability of use equations is noted. PMID:3721874

    In ambulatory care diagnostic and therapeutic procedures may only be applied if they have a positive recommendation from the Federal Joint Committee. Both physicians and patients are bound by this rule. Limitations of ambulatory care cannot be attributed to the existing rules applicable to the funding for ambulatory care services; they only affect the pecuniary interests of Statutory Health Insurance (SHI) accredited physicians which are beyond the control of the insured. The prescription of medical drugs, supplements and health aids is subject to stronger restrictions, which can pose a dilemma for physicians: on the one hand, they are allowed by law to prescribe even the most costly medical drugs to every insured patient, if required, but on the other hand, they will have to prepare themselves for drug recourse claims. This situation can be relieved by appropriately handling reviews of so-called average prescription limits. Physicians should support the exertion of indirect influence over their prescription behaviour through measures like substitution ("aut idem" principle) and discount contracts and also, they should actively commit themselves to this approach when facing their patients. Otherwise financial viability, especially with respect to the supply with medical drugs, of the statutory health insurance system will be at risk. Copyright (c) 2010. Published by Elsevier GmbH.

  12. Ambulatory measurement of knee motion and physical activity: preliminary evaluation of a smart activity monitor

    2006-09-01

    Full Text Available Abstract 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°.

    Since the American Academy of Pediatrics published its statement titled "Infection Prevention and Control in Pediatric Ambulatory Settings" in 2007, there have been significant changes that prompted this updated statement. Infection prevention and control is an integral part of pediatric practice in ambulatory medical settings as well as in hospitals. Infection prevention and control practices should begin at the time the ambulatory visit is scheduled. All health care personnel should be educated regarding the routes of transmission and techniques used to prevent the transmission of infectious agents. Policies for infection prevention and control should be written, readily available, updated every 2 years, and enforced. Many of the recommendations for infection control and prevention from the Centers for Disease Control and Prevention for hospitalized patients are also applicable in the ambulatory setting. These recommendations include requirements for pediatricians to take precautions to identify and protect employees likely to be exposed to blood or other potentially infectious materials while on the job. In addition to emphasizing the key principles of infection prevention and control in this policy, we update those that are relevant to the ambulatory care patient. These guidelines emphasize the role of hand hygiene and the implementation of diagnosis- and syndrome-specific isolation precautions, with the exemption of the use of gloves for routine diaper changes and wiping a well child's nose or tears for most patient encounters. Additional topics include respiratory hygiene and cough etiquette strategies for patients with a respiratory tract infection, including those relevant for special populations like patients with cystic fibrosis or those in short-term residential facilities; separation of infected, contagious children from uninfected children when feasible; safe handling and disposal of needles and other sharp medical devices; appropriate use of personal

    To improve hypertension management in peritoneal dialysis patients through CQI process. Using the 4-step problem-solving framework called the PDCA cycle-plan, do, check and act, we conducted a CQI program. One hundred and forty-five peritoneal dialysis patients dialyzed for more than 3 months participated in the study. In 49 prevalent patients, the incidence of uncontrolled hypertension (BP>or=140/90 mm Hg 1 mm Hg=0.133 kPa) decreased from 49% to 16.3% although there were no significant changes in antihypertensive medication and total fluid removal. The incidence of uncontrolled hypertension in incident patients decreased from 61.3% to 28%. Height normalized extracellular water decreased significantly. In males it was from (10.8+/-1.4) kg/m to (10.3+/-1.7) kg/m and in females (9.6+/-1.2) kg/m to (8.6+/-1.2) kg/m. CQI is a useful method in the management of hypertension in peritoneal dialysis patients.

    We evaluate the importance of cancer spread to the lymphatic system in the posterior triangle. The posterior triangle tissues of 51 radical neck specimens were serially sectioned and studied for metastic involvement. The findings were correlated with the findings in the anterior triangle and the primary tumor. Of the 51 neck operations performed, 25 were elective and 26 were therapeutic for carcinoma of the larynx, pharynx, and oral cavity. Metastasis in the anterior triangles was detected in 88.4% of the therapeutic group and in 24.0% of the elective group. However, no metastasis in the posterior triangel was found in either group, regardless of the site of the tumor. We suggest that the posterior triangle can be totally preserved in radical neck surgery, which may make preservation of the spinal accessory nerve a more likely practice.

    A 13-year-old boy was admitted to our hospital with complaints of posterior chest pain and dyspnea. Computed tomography and magnetic resonance imaging of the chest revealed a mass in the posterior mediastinum, extending from T8 to T11 with intraspinal involvement. A percutaneous core needle biopsy confirmed the diagnosis of Burkitt lymphoma. He was treated according to the Lymphoma Malignancy B protocol 2001 arm C3, but he presented with liver and brain relapses and died 7.5 months after admission. Although lymphoma is rarely localized in the posterior mediastinum, it should be considered in the differential diagnosis of posterior mediastinal masses in children. © The Author(s) 2015.

    The alien hand syndrome (AHS) is involuntary uncontrolled movement of an arm with a sense of estrangement from the limb itself. AHS was initially used to describe interhemispheric disconnection phenomena in patients with lesions in the anterior corpus callosum, but it has been found in patients with posterior cerebral lesions without involvement of the corpus callosum, for example parietal infarcts or corticobasal degeneration. The posterior alien hand syndrome is less frequent and presents with nonpurposive behaviour like lifting the arm or writhing fingers. We report an 80-year-old woman with a posterior AHS of the dominant right hand. MRI showed atrophy of the pre- and postcentral gyri without involvement of the corpus callosum. We discuss the aetiology of the posterior AHS and the differences from the anterior varieties. (orig.)

    Posterior reversible encephalopathy syndrome has been associated with hypertension, preeclampsia, cancer chemotherapy, and drugs of abuse, such as amphetamine and methamphetamine. We report a young man who suddenly developed severe headache, disorientation, and aphasia following ingestion of kratom and Adderall. Computed tomography and magnetic resonance imaging of his head revealed foci of vasogenic edema in the posterior occipital lobes, frontal lobes, and brainstem. In addition, he had a small area of hemorrhage in the left posterior occipital lobe. Lumbar puncture revealed an increased number of red blood cells but no other abnormalities. His initial blood pressure was elevated but returned to normal during hospitalization. This case suggests that kratom can cause posterior reversible encephalopathy syndrome and needs to be considered when patients present to emergency centers with headaches, confusion, and visual disturbances.

    The frequency and importance of the evaluation of the posterior fossa have increased significantly over the past 20 years owing to advances in neuroimaging. Nowadays, conventional and advanced neuroimaging techniques allow detailed evaluation of the complex anatomic structures within the posterior fossa. A wide spectrum of congenital abnormalities has been demonstrated, including malformations (anomalies due to an alteration of the primary developmental program caused by a genetic defect) and disruptions (anomalies due to the breakdown of a structure that had a normal developmental potential). Familiarity with the spectrum of congenital posterior fossa anomalies and their well-defined diagnostic criteria is crucial for optimal therapy, an accurate prognosis, and correct genetic counseling. The authors discuss the spectrum of posterior fossa malformations and disruptions, with emphasis on neuroimaging findings (including diagnostic criteria), neurologic presentation, systemic involvement, prognosis, and risk of recurrence.

    Outpatient plastic surgery is growing around the world. This industry faces unique challenges in terms of patient selection and standards of practice to ensure safety and cost-effectiveness. This review will highlight information about anesthesia practice for outpatient cosmetic surgery in Brazil, especially regarding regulation, legislation, and medical tourism. Medical tourism is growing worldwide, with a flow of patients traveling from developed to developing countries where procedures can be done at a fraction of the cost as in the patient's home country. Though generally well tolerated, there are concerns about incomplete data on outcomes of office-based surgeries and lack of safety standards. Brazil is one of the world's leaders in cosmetic surgery. Strong legislation governing outpatient facilities and continued development of accrediting standards for healthcare facilities are indications of a commitment to patient safety and high quality of care. Although the market for medical tourism in this country is high, there are still barriers to overcome before Brazil reaches its full potential in this industry.

    Full Text Available Abstract Background The role of small solute clearance on mortalities in patients with CAPD has been controversial. We therefore conducted a study with 3 years' follow up in adult patients who participated in the CAPD-first policy. Methods There were 11,523 patients with end-stage renal disease who participated in the CAPD-first policy between 2008 and 2011. Among them, 1,177 patients were included in the retrospective cohort study. A receiver operating characteristic curve was applied to calibrate the cutoffs of tKt/V, rKt/V and tCrcl. Kaplan-Meier and Cox-regression models with time varying covariates were applied to estimate overall death rate, probability of death and prognosis, respectively. Results The cutoffs of rKt/V and tKt/V were 0.25 and 1.75, respectively. The Cox regression suggested that the higher these clearance parameters, the lower the risks of death after adjusting for covariables. The risks of death for those above these cutoffs were 57% (HR = 0.43, 95% CI: 0.31, 0.60 and 29% (HR = 0.71, 95% CI: 0.52, 0.98 lower for rKt/V and tKt/V, respectively. Age, serum albumin, hemoglobin, systolic blood pressure, and ultra-filtration volume significantly affected the mortality outcome. Conclusions Our study suggested that the cutoffs of 0.25 and 1.75 for rKt/V and tKt/V might be associated with mortality in CAPD patients. A minimum tKt/V of 1.75 should be targeted, but increased dialysis dosage to achieve tKt/V > 2.19 adds no further benefit. Serum albumin, hemoglobin, SBP, and UF volume are also associated with mortality. However, our study may face with selection and other unobserved confounders, so further randomized controlled trials are required to confirm these cutoffs.

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

    Full Text Available Objective Unstable intertrochanteric fractures continue to be a challenge for orthopedic surgeons due to the functional limitations it results in the postoperative period. Anatomical reconstruction of the posteromedial fragment becomes difficult through conventional lateral approach, leading to excessive fracture collapse and limping. Materials and Methods: prospective, nonrandomized study was done with 40 patients. They were operated in prone position through posterior approach. Cancellous screws or SS-wires were used to fix the greater or lesser trochanteric fragments and dynamic hip screw (DHS or dynamic condylar screw (DCS for the main two fragments. Bone grafts were used to pack cavities at the posterior trochanteric regions. Results: Fracture healing occurred earlier compared to conventional lateral approach without excessive fracture collapse in majority of cases (average time to achieve union was 13.8 weeks; range: 10–18 weeks. Good functional recovery was noted with 75% 'Good' or 'Excellent' Harris Hip Scores at 24 weeks. Conclusion: Anatomical reconstruction of unstable trochanteric fractures becomes easier through posterior approach with earlier and better functional recovery.

    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 th...

    • To report the early observations of using ambulatory urodynamic studies (UDS) using a Bluetooth-enabled device in children • To evaluate the incremental value of ambulatory over conventional UDS. • Ambulatory UDS were performed in selected children with voiding dysfunction between August 2009 and October 2010. • Conventional UDS were concurrently performed wherever possible. • The test results and treatment consequences of the two tests were compared. • In all, 12 ambulatory and seven conventional UDS were performed on 10 children (five boys, median [range] age 7 [4-16] years). • Six of the seven children had a normal conventional UDS. Ambulatory UDS detected phasic detrusor overactivity (DO) in five children and generalised DO in one. • Direct correlation of symptoms to DO was possible in two children during ambulatory UDS. Pressure rise during filling, seen in two children on conventional UDS, was not seen during ambulatory UDS. • Five children showed clinical improvement when therapy was guided by ambulatory UDS results. • Ambulatory UDS was generally well tolerated in eight children, with two complaining of discomfort. Inadequate information was obtained in two children who underwent ambulatory UDS due to technical problems in one and distress induced by the UDS in the other. • Ambulatory UDS provides useful additional information over conventional UDS and can be used to guide further therapy in selected children with voiding dysfunction. • It is safe and well tolerated in children. • There is a need for explicit guidance for the technical delivery and interpretation of ambulatory UDS in children. © 2012 THE AUTHORS.

    Objective: To determine the delayed single stage perineal posterior urethroplasty for treatment of posterior urethral stricture/distraction defect. Study Design: Descriptive case series. Place and Duration of Study: Department of Urology, Jinnah Postgraduate Medical Centre, Karachi, from January 2009 to December 2011. Methodology: Patients were selected for delayed single stage perineal posterior urethroplasty for treatment of posterior urethral stricture / distraction defect. All were initially suprapubically catheterized followed by definitive surgery after at least 3 months. Results: Thirty male patients were analyzed with a mean follow-up of 10 months, 2 patients were excluded as they developed failure in first 3 months postoperatively. Mean patients age was 26.25 ± 7.9 years. On follow-up, 7 patients (23.3 percentage) experienced recurrent stricture during first 10 months. Five (16.6 percentage) patients were treated successfully with single direct visual internal urethrotomy. Two patients (6.6 percentage) had more than one direct visual internal urethrotomy and considered failed. Re-do perineal urethroplasty was eventually performed. The overall success rate was 93.3 percentage with permissive criteria allowing single direct visual internal urethrotomy and 76.6% with strict criteria allowing no more procedures postoperatively. Conclusion: Posterior anastomotic urethroplasty offers excellent long-term results to patients with posterior urethral trauma and distraction defect even after multiple prior procedures. (author)

    Posterior urethral injury requires meticulous tertiary care and optimum expertise to manage successfully. The aim of our study is to describe our experiences with pelvic injuries involving posterior urethra and their outcome after early endoscopic realignment. A prospective study was carried out in 20 patients with complete posterior urethral rupture, from November 2007 till October 2010. They presented with blunt traumatic pelvic fracture and underwent primary realignment of posterior urethra in our institute. The definitive diagnosis of urethral rupture was made after retrograde urethrography and antegrade urethrography where applicable. The initial management was suprapubic catheter insertion after primary trauma management in casualty. After a week of conservative management with intravenous antibiotics and pain management, patients were subjected to the endoscopic realignment. The follow up period was at least six months. The results were analyzed with SPSS software. After endoscopic realignment, all patients were advised CISC for the initial 3 months. All patients voided well after three months of CISC. However, 12 patients were lost to follow up by the end of 6 postoperative months. Out of eight remaining patients, two had features of restricture and were managed with DVU followed by CISC again. One patient with restricture had some degree of erectile dysfunction who improved significantly after phospodiesterase inhibitors. None of the patients had features of incontinence. Early endoscopic realignment of posterior urethra is a minimally invasive modality in the management of complete posterior urethral injury with low rates of incontinence and impotency.

    The posterior urethral lesions are associated with pelvis fractures in 5-10% of cases. The posterior urethra is attached to the pelvis bone by puboprostatic ligaments and the perineal membrane, which explains why disruption of the pelvic ring can injure the urethra at this level. To identify suspected cases of posterior urethral trauma and to perform the diagnosis and its immediate or deferred management. Search in PubMed of articles related to traumatic posterior urethral lesions, written in English or Spanish. We reviewed the relevant publications including literature reviews and chapters from books related to the topic. With patients with pelvis fractures, we must always rule out posterior urethral lesions. The diagnostic examination of choice is retrograde urethrography, which, along with the severity of the condition, will determine the management in the acute phase and whether the treatment will be performed immediately or deferred. Early diagnosis and proper acute management decrease the associated complications, such as strictures, urinary incontinence and erectile dysfunction. Despite the classical association between posterior urethral lesions and pelvic fractures, the management of those lesions (whether immediate or deferred) remains controversial. Thanks to the growing interest in urethral disease, there are an increasing number of studies that help us achieve better management of these lesions. Copyright © 2016 AEU.

    2008-06-01

    Full Text Available Background: For the purpose of ascertaining myocardial infarction (MI and ischemia, the sensitivity of the initial 12-lead ECG is inadequate. It is risky to diagnose posterior MI using only precordial reciprocal changes, since the other leads may be more optimally positioned for the identification of electrocardiographic changes. In this study, we evaluated the relationship between electrocardiography changes and wall motion abnormalities in patients with posterior MI for earlier and better diagnosis of posterior MI.Methods: In this prospective cross-sectional study, we enrolled patients with posterior MI who had come to the Emergency Department of Shariati Hospital with their first episode of chest pain. A 12-lead surface electrocardiogram using posterior leads (V7-V9 was performed for all participants. Patients with ST elevation >0.05 mV or pathologic Q wave in the posterior leads, as well as those with specific changes indicating posterior MI in V1-V2, were evaluated by echocardiography in terms of wall motion abnormalities. All data were analyzed using SPSS and p<0.05 were considered statistically significant.Results: Of a total 79 patients enrolled, 48 (60.8% were men, and the mean age was 57.35±8.22 years. Smoking (54.4% and diabetes (48% were the most prevalent risk factors. In the echocardiographic evaluation, all patients had wall motion abnormalities in the left ventricle and 19 patients (24.1% had wall motion abnormalities in the right ventricle. The most frequent segment with motion abnormality among the all patients was the mid-posterior. The posterior leads showed better positive predictive value than the anterior leads for posterior wall motion abnormality.Conclusion: Electrocardiography of the posterior leads in patients with acute chest pain can help in earlier diagnosis and in time treatment of posterior MI.

    The preservation of joint anatomy is one of the key issues in total knee arthroplasty. The effect of the prosthesis' referencing system, relative to femoral anatomy, remains unknown. It was sought to determine if femoral anatomy, following total knee arthroplasty is better maintained using either anterior referencing or posterior referencing prosthesis. The posterior condylar offset ratio (PCOR) was employed for preoperative and postoperative radiographic comparison of femoral condyles. It was hypothesized that posterior referencing prosthesis would better restore condylar morphology. Sixty-six patients undergoing a total knee arthroplasty with anterior referenced Zimmer(®) NexGen(®) LPS prosthesis and ninety-one with posterior referenced Tornier(®) HLS Noetos(®) were divided into two groups according to the prosthetic model used and retrospectively compared. PCOR was calculated as the quotient of the distance between the posterior condylar border and the tangent to the posterior cortex of the femoral diaphysis, and the distance between the posterior condylar border and the tangent to the anterior cortex of the femoral diaphysis. PCOR was determined preoperatively and postoperatively and compared within each group and between both groups. An increase in the PCOR (Panterior referencing and posterior referencing models. No difference was noted when the postoperative PCOR was compared between both groups (P=0.61). Both anterior and posterior referencing prosthesis lead to a similar increase of the PCOR following total knee arthroplasty. Level IV. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    To examine whether continuity of ambulatory asthma care can lower asthma-specific emergency department (ED) utilization by children with asthma in Taiwan. Retrospective cohort study based on claims data. We used the Taiwan National Health Insurance Dataset, 2006 to 2009. The study population was new asthma patients aged 0 to 17 years in 2007, and every case was observed for 2 years. We used the Continuity of Care Index (COCI) to calculate the continuity of ambulatory asthma care in the first year, and estimated the asthma-specific ED utilization in the second year. Two-part hurdle regression was used for statistical analysis. The 29,277 patients in our study had an average COCI of 0.68 (± 0.31), and 42.3% of patients had an index of 1. More than 1 in 20 patients-1641 (5.61%)-had at least 1 asthma ED visit, and the mean number of visits per user was 1.46 (± 0.99). After controlling for covariates, the groups with medium and low continuity of ambulatory asthma care had 21% (odds ratio [OR], 1.21; 95% CI, 1.06-1.39) and 38% (OR, 1.38; 95% CI, 1.21-1.58) higher asthma-related ED utilization, respectively, than the group with high COCI. However, among users, the number of ED visits was not statistically correlated to the continuity of ambulatory asthma care. High continuity of ambulatory asthma care can decrease asthma-specific ED utilization risk in children with newly diagnosed asthma in Taiwan. We suggest that providers and the government reinforce the use of follow-up care and education for high-risk groups to improve the continuity of ambulatory asthma care.

    To study the experimental biomechanics of acetabular posterior wall fractures so as to provide theoretical basis for its clinical treatment. Six formalin-preserved cadaveric pelvises were divided into groups A and B (n=3). The fracture models of superior-posterior wall and inferior-posterior wall of the acetabulum were created on both hips in group A; fractures were fixed with two interfragmentary screws and a locking reconstruction plate. The fracture models of superior-posterior wall of acetabulum were created on both hips in group B; fractures were fixed with two interfragmentary screws and a locking reconstruction plate at one side, and with acetabular tridimensional memory fixation system (ATMFS) at the other side. The biomechanical testing machine was used to load to 1 500 N at 10 mm/min speed for 30 seconds. The displacement of superior and inferior fracture sites was analyzed with the digital image correlation technology. No fracture or internal fixation breakage occurred during loading and measuring; the displacement valuess of the upper and lower fracture lines were below 2 mm (the clinically tolerable maximum value) in 2 groups. In group A, the displacement values of the upper and lower fracture lines at superior-posterior wall fracture site were significantly higher than those at inferior-posterior wall fracture site (P fracture line were significantly higher than those of lower fracture line (P fracture types. In group B, the displacement values of the upper and lower fracture lines at the side fixed with screws and a locking reconstruction plate were similar to the values at the side fixed with ATMFS, all being close to 2 mm; the displacement values of the upper fracture line were significantly higher than those of lower fracture line (P acetabulum is much greater than that of the inferior-posterior wall of acetabulum and they should be discriminated, which might be the reasons of reduction loss, femoral head subluxation, and traumatic arthritis

    Sleep disordered breathing (SDB) symptoms are associated with increased rates of opioid-induced respiratory depression as well as enhanced nociception. Consequently, practitioners often withhold or administer lower intraoperative doses of opioids out of concern for postoperative respiratory depression. Therefore, SDB may be a critical determinant of analgesic requirement in the post-anesthesia care unit (PACU). We investigated whether preoperative SDB classification was independently associated with need for PACU analgesic intervention in a cross-sectional sample of 985 children who underwent elective, painful ambulatory surgical procedures. Using prospectively collected data, children aged 4-17yr were grouped into two categories based on whether or not they had symptoms of SDB. Perioperative variables were compared between the exposed and control groups using Chi-squared test for categorical or t-test for continuous variables. Logistic regression analysis was used to assess the association between SDB and the odds of requiring PACU IV opioids. Children with preoperative SDB symptoms (N = 325) compared with the reference group of children who did not have these symptoms had higher rates of PACU analgesic intervention (47.1% vs. 37.4%; p = 0.004) and higher mean arousal pain scores (3.7 ± 3.5 vs.1.9 ± 2.9; p children undergoing ambulatory surgery, exerts a significant influence on PACU pain behavior and analgesic requirement. Mechanisms underlying this enhanced pain experience deserve further elucidation. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available INTRODUCTION Renal scarring is the most common cause of arterial hypertension in children. High blood pressure (BP and microalbuminuria contribute to the progression of chronic renal disease. OBJECTIVE The aims of the study were: to assess BP in children with renal scarring by continuous ambulatory blood pressure measurement (ABPM in comparison to the casual method (CBP, and to determine the correlation between ambulatory blood pressure (ABP and/or casual blood pressure (CBP values and proteinuria in children with renal scarring. METHOD This forward-looking study comprised thirty-five children (26 girls and 9 boys, aged between 3-13 years, 10.4±3.9, X+SD. Blood pressure was measured using the casual method (CBP with a mercury manometer; BP was measured three times and the average was taken as a referent value. ABPM was performed using the oscillometric method with the Space Labs device, model 90207. RESULTS 45.71% of patients were classified as hypertensive by ABPM, while only 22.6% of CBP measurements were above the 95th percentile (p<0.01. "White coat hypertension" was present in 40% of the patients. Non-dipping BP alteration was detected in 37.14% of the patients. CONCLUSION Nocturnal systolic hypertension (systolic non-dipping alteration is very frequent in children with renal scarring. Nocturnal diastolic blood pressure, detectable only via ABPM, is positively correlated with proteinuria and may be an initial sign of the progression of renal scarring. ABPM is more sensitive than CBP in the evaluation of BP in children with renal scarring.

    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.

    Full Text Available Abstract Background Hemodialysis (HD patients are at risk for medication-related problems (MRP. The MRP number, type, and appearance rate over time in ambulatory HD patients has not been investigated. Methods Randomly selected HD patients were enrolled to receive monthly pharmaceutical care visits. At each visit, MRP were identified through review of the patient chart, electronic medical record, patient interview, and communications with other healthcare disciplines. All MRP were categorized by type and medication class. MRP appearance rate was determined as the number of MRP identified per month/number of months in study. The number of MRP per patient-drug exposures were determined using: {[(number of patients × (mean number of medications]/(number of months of study} /number of MRP identified. Results were expressed as mean ± standard deviation or percentages. Results Patients were 62.6 ± 15.9 years old, had 6.4 ± 2.0 comorbid conditions, were taking 12.5 ± 4.2 medications, and 15.7 ± 7.2 doses per day at baseline. Medication-dosing problems (33.5%, adverse drug reactions (20.7%, and an indication that was not currently being treated (13.5% were the most common MRP. 5,373 medication orders were reviewed and a MRP was identified every 15.2 medication exposures. Overall MRP appearance rate was 0.68 ± 0.46 per patient per month. Conclusion MRP continue to occur at a high rate in ambulatory HD patients. Healthcare providers taking care of HD patients should be aware of this problem and efforts to avoid or resolve MRP should be undertaken at all HD clinics.

    Ambulatory blood pressure monitoring (ABPM) is the best method of detecting abnormal blood pressure (BP) in patients with chronic kidney disease (CKD), whose hypertension may be missed with office BP measurements. We report ABPM findings in 332 children 1 year after entry in the Chronic Kidney Disease in Children (CKiD) cohort study. All subjects underwent casual and ambulatory BP measurement. BP was categorized based on casual and ABPM results into normal, white coat, masked, and ambulatory hypertension. Only half of the subjects had a normal ABPM. BP load was elevated (>25%) in 52% (n= 172) while mean BP was elevated in 32% (n= 105). In multivariate analysis, those using an ACE inhibitor (ACEi) were 89% more likely to have a normal ABPM than those who did not report using an ACEi (OR: 1.89, 95%CI: 1.17, 3.04). For every 20% faster decline in annualized GFR change, the odds of an abnormal ABPM increased 26% (OR: 1.26, 95%CI: 0.97, 1.64; p= 0.081). A 2.25 fold increase in urine protein:creatinine ratio annualized change was associated with a 39% higher odds of an abnormal ABPM (OR: 1.39, 95%CI: 1.06, 1.82; p= 0.019). Abnormalities on ABPM are common in children with CKD, and are strongly associated with known risk factors for end stage renal disease. Individuals on ACEi were less likely to have abnormal ABPM, suggesting a possible therapeutic intervention. ABPM should be used to monitor risk and guide therapy in children with CKD. PMID:22585950

    Worldwide, a large number of children are prescribed drugs on an outpatient basis. Medication errors are fairly common in these settings. Though this matter has been well recognized as a cause of concern, limited data is available from ambulatory settings. Medication errors can be defined as errors that may occur at any step, starting from ordering a medication, to dispensing, administration of the drug and the subsequent monitoring. The outcomes of such errors are variable and may range between those that are clinically insignificant to a life-threatening event. The reasons for these medication errors are multi-factorial. Children are unable to administer medications to themselves and also require a strict weight-based dosing regimen. The risk factors associated with medication errors include complex regimens with multiple medications. Overdosing and under-dosing (10-fold calculation errors), an increased or a decreased frequency of dosing or an inappropriate duration of administration of the medication, are frequently detected errors. The lack of availability of proper formulations adds to the confusion. The low level of literacy among the caregivers can aggravate this problem. There is a lack of proper reporting and monitoring mechanisms in most ambulatory settings, hence these errors remain unrecognized and often go unreported. This article summarizes the current available literature on medication errors in ambulatory settings and the possible strategies that can be adopted to reduce the burden of these errors in order to improve child care and patient safety. Voluntary, anonymous reporting can be introduced in the healthcare institutions to determine the incidence of these errors.

    Social support has been associated with greater nocturnal decline (dipping) in blood pressure (BP) in younger and middle-aged individuals. However, it is uncertain if aggregated measures of social support are related to ambulatory SBP in older adults, where high SBP is frequent and clinically challenging. We studied 1047 community-living individuals aged at least 60 years in Spain. Twenty-four-hour ambulatory BP was determined under standardized conditions. Social support was assessed with a seven-item questionnaire on marital status, cohabitation, frequency of contact with relatives, or with friends and neighbors, emotional support, instrumental support, and outdoor companionship. A social support score was built by summing the values of the items that were significantly associated with SBP variables, such that the higher the score, the better the support. Participants' mean age was 71.7 years (50.8% men). Being married, cohabiting, and being accompanied when out of home were the support items significantly associated with SBP variables. After adjustment for sociodemographic (age, sex, education), behavioral (BMI, alcohol, tobacco, salt consumption, physical activity, Mediterranean diet score), and clinical variables [sleep quality, mental stress, comorbidity, BP medication, and ambulatory BP levels and heart rate (HR)], one additional point in the social support score built with the abovementioned three support variables, was associated with a decrease of 0.93 mmHg in night-time SBP (P = 0.039), totaling 2.8 mmHg decrease for a score of 3 vs. 0. The three-item social support score was also inversely associated with the night/day SBP ratio (β = -0.006, P = 0.010). In older adults, social support is independently associated with lower nocturnal SBP and greater SBP dipping. Further research is needed in prospective studies to confirm these results.

    Full Text Available Daniela Ghisi, Stefano Bonarelli Department of Anaesthesia and Postoperative Intensive Care, Istituto Ortopedico Rizzoli, Bologna, Italy Abstract: Spinal anesthesia is a reliable and safe technique for procedures of the lower extremities. Nevertheless, some of its characteristics may limit its use for ambulatory surgery, including delayed ambulation, risk of urinary retention, and pain after block regression. The current availability of short-acting local anesthetics has renewed interest for this technique also in the context of short- and ultra-short procedures. Chloroprocaine (CP is an amino-ester local anesthetic with a very short half-life. It was introduced and has been successfully used for spinal anesthesia since 1952. Sodium bisulfite was then added as a preservative after 1956. The drug was then abandoned in the 1980s for several reports of neurological deficits in patients receiving accidentally high doses of intrathecal CP during epidural labor analgesia. Animal studies have proven the safety of the preservative-free formulation, which has been extensively evaluated in volunteer studies as well as in clinical practice with a favorable profile in terms of both safety and efficacy. In comparison with bupivacaine, 2-chloroprocaine (2-CP showed faster offset times to end of anesthesia, unassisted ambulation, and discharge from hospital. These findings suggests that 2-CP may be a suitable alternative to low doses of long-acting local anesthetics in ambulatory surgery. Its safety profile also suggests that 2-CP could be a valid substitute for intrathecal short- and intermediate-acting local anesthetics, such as lidocaine and mepivacaine – often causes of transient neurological symptoms. In this context, literature suggests a dose ranging between 30 and 60 mg of 2-CP for procedures lasting 60 minutes or less, while 10 mg is considered the no-effect dose. The present review describes recent evidence about 2-CP as an anesthetic agent for

    Objective ambulatory activity during daily living has not been characterized for people with Parkinson disease prior to initiation of dopaminergic medication. Our goal was to characterize ambulatory activity based on average daily step count and examine determinants of step count in nonexercising people with de novo Parkinson disease. We analyzed baseline data from a randomized controlled trial, which excluded people performing regular endurance exercise. Of 128 eligible participants (mean ± SD = 64.3 ± 8.6 years), 113 had complete accelerometer data, which were used to determine daily step count. Multiple linear regression was used to identify factors associated with average daily step count over 10 days. Candidate explanatory variable categories were (1) demographics/anthropometrics, (2) Parkinson disease characteristics, (3) motor symptom severity, (4) nonmotor and behavioral characteristics, (5) comorbidities, and (6) cardiorespiratory fitness. Average daily step count was 5362 ± 2890 steps per day. Five factors explained 24% of daily step count variability, with higher step count associated with higher cardiorespiratory fitness (10%), no fear/worry of falling (5%), lower motor severity examination score (4%), more recent time since Parkinson disease diagnosis (3%), and the presence of a cardiovascular condition (2%). Daily step count in nonexercising people recruited for this intervention trial with de novo Parkinson disease approached sedentary lifestyle levels. Further study is warranted for elucidating factors explaining ambulatory activity, particularly cardiorespiratory fitness, and fear/worry of falling. Clinicians should consider the costs and benefits of exercise and activity behavior interventions immediately after diagnosis of Parkinson disease to attenuate the health consequences of low daily step count.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A170).

    We describe a mixed-effects model for nonnegative continuous cross-sectional data in a two-part modelling framework. A potentially endogenous binary variable is included in the model specification and association between the outcomes is modeled through a (discrete) latent structure. We show how model parameters can be estimated in a finite mixture context, allowing for skewness, multivariate association between random effects and endogeneity. The model behavior is investigated through a large-scale simulation experiment. The proposed model is computationally parsimonious and seems to produce acceptable results even if the underlying random effects structure follows a continuous parametric (e.g. Gaussian) distribution. The proposed approach is motivated by the analysis of a sample taken from the Medical Expenditure Panel Survey. The analyzed outcome, that is ambulatory health expenditure, is a mixture of zeros and continuous values. The effects of socio-demographic characteristics on health expenditure are investigated and, as a by-product of the estimation procedure, two subpopulations (i.e. high and low users) are identified. © 2015 WILEY-VCH Verlag GmbH & Co.

    Full Text Available This study proposes the use of flexible capacitive electrodes for reducing motion artifacts in a wearable electrocardiogram (ECG device. 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. The results confirmed the highly accurate heart rate detection capacity of the developed system and its feasibility for daily-life ECG monitoring.

    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%.

    Molecular diagnostics methods are not limited to specialized centers anymore. They play an important role for the diagnostic of infections commonly encountered in the clinical practice. Especially the detection of pathogens difficult to cultivate, such as viruses, has been greatly improved by these methods. Often, PCR has become the gold standard for the diagnostics of these pathogens. However, PCR cannot be used in any case, and it is not fail proof. Therefore, it is important to know when to use molecular methods and what are their strengths and weaknesses, in order to prescribe them rationally. This article reviews the characteristics of molecular tests and their main indications in the ambulatory setting.

  17. Management of posterior urethral disruption injuries.

    Myers, Jeremy B; McAninch, Jack W

    2009-03-01

    Posterior urethral disruption is a traumatic injury to the male urethra, which most often results from pelvic fracture. After trauma, the distraction defect between the two ends of the urethra often scars and becomes fibrotic, blocking the urethra and bladder emptying. Increasing evidence suggests that many posterior urethral disruptions occur at the junction between the membranous urethra and the bulbar urethra, which is distal to the rhabdosphincter. In the acute setting, when a posterior urethral disruption is suspected, retrograde urethrography should be performed. Posterior urethral disruptions can be managed acutely by realignment of the urethra over a urethral catheter or by placement of a suprapubic catheter for bladder drainage only. Once fibrosis has stabilized, the patient can undergo posterior urethroplasty. In most cases, this procedure can be performed via a perineal approach in a single-stage surgery. The results of this single-stage perineal urethroplasty are excellent, and a patent urethra can be re-established in the majority of men who undergo surgery.

    Full Text Available We evaluated the safety and efficacy of pars plana vitrectomy (PPV with primary posterior iris claw intraocular lens (IOL implantation in cases of posterior dislocation of nucleus and IOL without capsular support. This was a retrospective interventional case series. Fifteen eyes underwent PPV with primary posterior iris claw IOL implantation performed by a single vitreoretinal surgeon. The main outcome measures were changes in best corrected visual acuity and anterior and posterior segment complications. A total of 15 eyes were included in this study. Eight had nucleus drop, three had IOL drop during cataract surgery and four had traumatic posterior dislocation of lens. The final postoperative best corrected visual acuity was 20/60 or better in 11 patients. This procedure is a viable option in achieving good functional visual acuity in eyes without capsular support.

    Presence of posterior urethral valves (PUV) is the most common cause of urinary tract obstruction in the male neonate. Late presentation occurs in 10% of cases. We present a case of PUVs in an adult male who presented with history of obstructive lower urinary tract symptoms and hematuria. On evaluation, he was found to have raised serum creatinine level. A voiding cystourethrogram (VCUG) could not be completely performed because of narrowing in the posterior urethra. A rigid urethrocystoscopy was performed at which he was found to have type-I posterior urethral valve which were fulgurated. A repeat uroflowmetry revealed maximum flow rate of 12 ml/second. This case highlights that PUVs is not solely a disease of infancy but may also present late. VCUG is the radiological investigation of choice but the diagnosis may be missed. A urethrocystoscopy is advised if there is a high index of suspicion.

    Multiple imputation is gaining popularity as a strategy for handling missing data, but there is a scarcity of tools for checking imputation models, a critical step in model fitting. Posterior predictive checking (PPC) has been recommended as an imputation diagnostic. PPC involves simulating "replicated" data from the posterior predictive distribution of the model under scrutiny. Model fit is assessed by examining whether the analysis from the observed data appears typical of results obtained from the replicates produced by the model. A proposed diagnostic measure is the posterior predictive "p-value", an extreme value of which (i.e., a value close to 0 or 1) suggests a misfit between the model and the data. The aim of this study was to evaluate the performance of the posterior predictive p-value as an imputation diagnostic. Using simulation methods, we deliberately misspecified imputation models to determine whether posterior predictive p-values were effective in identifying these problems. When estimating the regression parameter of interest, we found that more extreme p-values were associated with poorer imputation model performance, although the results highlighted that traditional thresholds for classical p-values do not apply in this context. A shortcoming of the PPC method was its reduced ability to detect misspecified models with increasing amounts of missing data. Despite the limitations of posterior predictive p-values, they appear to have a valuable place in the imputer's toolkit. In addition to automated checking using p-values, we recommend imputers perform graphical checks and examine other summaries of the test quantity distribution. © 2015 WILEY-VCH Verlag GmbH & Co.

    Six examples of a previously undescribed class of transverse vertebral element fractures are presented. These fractures differ from Chance and Smith fractures and their variants in the following respects: (1) the etiology is torsion and not flexion; (2) there is neither distraction of posterior ring fragments nor posterior ligament tears; (3) in contrast to Chance and Smith fractures, extension of the fracture into the vertebral body is absent or minimal; (4) the transverse process of the lumbar vertebra is avulsed at its base with a vertical fracture, not split horizontally. These fractures occur in cervical, lumbar, and sacral vertebrae in normal or compromised areas of the spine. (orig.)

    Traumatic sternoclavicular joint dislocation is an uncommon injury, and posterior sternoclavicular dislocation occurs less frequently compared to anterior sternoclavicular dislocation. However, this type of dislocation has the potential for serious complications due to compression or laceration of the mediastinal structures. The diagnosis can be difficult using plain radiographs alone due to radiographic-anatomic superimposition. Therefore, posterior sternoclavicular dislocation is easily missed at the initial clinical evaluation. Contrast-enhanced computed tomography is required for a definite diagnosis and to assess associated mediastinal injuries.

    Reversible posterior leukoencephalopathy (LEPR) is a clinical entity that affects radiation usually the white matter of the cerebral hemispheres. It is frequently associated with acute arterial hypertension and immunosuppressive therapy, among other causes. The clinical presentation is varied, with headache, nausea, vomiting, impaired consciousness and abnormal behavior, seizures and visual disturbances, symptoms that often regress. Computed tomography (CT) and magnetic resonance imaging (MRI) images show white matter edema predominantly in posterior regions of the brain. We present a 10 year old boy with leprosy in the course of a nephrotic syndrome secondary to acute diffuse glomerunefritis (GNDA) poststreptococcal. (author) [es

  9. Pain Management in Ambulatory Surgery—A Review

    Jan G. Jakobsson

    2014-07-01

    Full Text Available 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.

    As part of the American College of Cardiology Adult Congenital and Pediatric Cardiology Section effort to develop quality metrics (QMs) for ambulatory pediatric practice, the chest pain subcommittee aimed to develop QMs for evaluation of chest pain. A group of 8 pediatric cardiologists formulated candidate QMs in the areas of history, physical examination, and testing. Consensus candidate QMs were submitted to an expert panel for scoring by the RAND-UCLA modified Delphi process. Recommended QMs were then available for open comments from all members. These QMs are intended for use in patients 5-18 years old, referred for initial evaluation of chest pain in an ambulatory pediatric cardiology clinic, with no known history of pediatric or congenital heart disease. A total of 10 candidate QMs were submitted; 2 were rejected by the expert panel, and 5 were removed after the open comment period. The 3 approved QMs included: (1) documentation of family history of cardiomyopathy, early coronary artery disease or sudden death, (2) performance of electrocardiogram in all patients, and (3) performance of an echocardiogram to evaluate coronary arteries in patients with exertional chest pain. Despite practice variation and limited prospective data, 3 QMs were approved, with measurable data points which may be extracted from the medical record. However, further prospective studies are necessary to define practice guidelines and to develop appropriate use criteria in this population. © 2017 Wiley Periodicals, Inc.

    This study aims to investigate the level of satisfaction of care received among patients undergoing ambulatory surgery in two hospitals in Iceland, using the Patient Satisfaction Instrument (PSI). The PSI consists of 25 items, broken down into three sub-scales which measure the patients' attitude towards nursing care. The sample consisted of ambulatory patients undergoing orthopaedic, urological, hernia or varicose veins operations. The patients were 16 years or older and we enlisted 70 individuals from each hospital. Overall, the results show that patients are generally satisfied with the level of care they have received. The patients in group I are more satisfied than the patients in group II; however, only four out of the 25 items which were scored attracted a significance level of nurses as satisfactory but felt they did not receive enough information about their operation from the nurses. Although the patients were generally satisfied with the level of care received, they also identified instances where they felt that the level of care was inadequate; however, as results from other studies show, patients often experience difficulties articulating something negative about their nurses and the care they have received.

    Full Text Available Introduction: Ambulatory Care Sensitive Conditions (ACSC are illnesses that could be prevented with adjusted ambulatorial care. ACSC have been used as indicator in effectiveness of the primary healthcare attention, through the evaluation of hospital admissions. However, we do not have studies to certify the reliability of diagnosis of ACSC in our country. Objective: To determine if the classification of ACSC from the main diagnostic field of the authorization of hospital internment (AHI is reliable. Methods: Transversal study carried through February of 2010 to January of 2011, in the city of Santa Cruz of Sul (RS. A random sample of 389 medical records was selected and evaluated by two medical appraisers. The main diagnosis in the AHI was compared with the classification in ACSC or not ACSC given for the appraisers after the study of each medical record. Kappa ratio agreement was used to calculate the reliability of the ACSC diagnostic. Results: The ratio of agreement between diagnosis from the AIH and CSAP assessment contained in the records was 92%, with a kappa coefficient of 0,784. Conclusions: The diagnostic of ACSC found in main diagnostic field of AHI showed agreement ratios over expected by chance, with kappa value equal to 0.784 and the correlation rated between substantial and almost perfect.

    Up to 60% of syncopal episodes remain unexplained. We report the results of a standardized, stepwise evaluation of patients referred to an ambulatory clinic for unexplained syncope. We studied 939 consecutive patients referred for unexplained syncope, who underwent a standardized evaluation, including history, physical examination, electrocardiogram, head-up tilt testing (HUTT), carotid sinus massage (CSM) and hyperventilation testing (HYV). Echocardiogram and stress test were performed when underlying heart disease was initially suspected. Electrophysiological study (EPS) and implantable loop recorder (ILR) were used only in patients with underlying structural heart disease or major unexplained syncope. We identified a cause of syncope in 66% of patients, including 27% vasovagal, 14% psychogenic, 6% arrhythmias, and 6% hypotension. Noninvasive testing identified 92% and invasive testing an additional 8% of the causes. HUTT yielded 38%, CSM 28%, HYV 49%, EPS 22%, and ILR 56% of diagnoses. On average, patients with arrhythmic causes were older, had a lower functional capacity, longer P-wave duration, and presented with fewer prodromes than patients with vasovagal or psychogenic syncope. A standardized stepwise evaluation emphasizing noninvasive tests yielded 2/3 of causes in patients referred to an ambulatory clinic for unexplained syncope. Neurally mediated and psychogenic mechanisms were behind >50% of episodes, while cardiac arrhythmias were uncommon. Sudden syncope, particularly in older patients with functional limitations or a prolonged P-wave, suggests an arrhythmic cause.

    To determine the effects of the adoption of ambulatory electronic health information exchange (HIE) on rates of laboratory and radiology testing and allowable charges. Claims data from the dominant health plan in Mesa County, Colorado, from 1 April 2005 to 31 December 2010 were matched to HIE adoption data on the provider level. Using mixed effects regression models with the quarter as the unit of analysis, the effect of HIE adoption on testing rates and associated charges was assessed. Claims submitted by 306 providers in 69 practices for 34 818 patients were analyzed. The rate of testing per provider was expressed as tests per 1000 patients per quarter. For primary care providers, the rate of laboratory testing increased over the time span (baseline 1041 tests/1000 patients/quarter, increasing by 13.9 each quarter) and shifted downward with HIE adoption (downward shift of 83, prates or imputed charges in either provider group. Ambulatory HIE adoption is unlikely to produce significant direct savings through reductions in rates of testing. The economic benefits of HIE may reside instead in other downstream outcomes of better informed, higher quality care.

  15. Blood Pressure Measurement: Clinic, Home, Ambulatory, and Beyond

    2014-01-01

    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

    The aim of this study was to perform a systematic review of clinical trials covering interventions used as prophylaxis for oral mucositis induced by ambulatory antineoplastic chemotherapy. Oral mucositis in patients undergoing chemotherapy is a side effect that can impact the quality of treatment and can interfere with eating and therapeutic adherence. Quantitative systematic review. Relevant databases were searched, from January 2002-July 2013, by using the combination of the keywords mucositis, stomatitis, neoplasms, antineoplastic agents, drug therapy, prevention and control and chemotherapy. Two researchers independently read the titles and abstracts from every cross-reference. The quality of the included studies was analysed by the Jadad Scale and the Cochrane Collaboration Risk of Bias Tool. Data were extracted from the selected studies with a data collection form developed specifically for this purpose. Of the 23 controlled clinical trials that were identified in this study, five articles evaluated the use of oral cryotherapy to prevent oral mucositis and three studies analysed the prophylactic use of glutamine. Interventions of protocols for oral care, palifermin, allopurinol and chlorhexidine were evaluated by two articles each. Interventions of zinc sulphate, amifostine, chewing gum, sucralfate, recombination human intestinal trefoil factor, kefir and vitamin E were evaluated by one article each. There is strong evidence that cryotherapy can prevent oral mucositis arising from ambulatory treatment with 5-flurouracil chemotherapy. Other interventions, although showing positive results in preventing oral mucositis, require further study to confirm their conclusions. © 2015 John Wiley & Sons Ltd.

    2015-01-01

    Ambulatory Emergency Care is a key component of the service for many Acute Medical units across the United Kingdom. A well-functioning ambulatory care unit facilitiates early senior review by a consultant and may reduce the need for hospital admission by managing patients along alternative safe clinical pathways. In this article, we present 12 months of data (January 2014-January 2015) from our Ambulatory Unit at Wrightington, Wigan and Leigh NHS Foundation Trust (WWL NHSFT), which demonstrates how many different conditions can be safely managed along ambulatory care pathways and how this can significantly contribute to postive patient satisfaction survey results and meeting the A&E 4 hour target for a medium-sized Acute Trust such as WWL NHSFT. We also emphasise that the key factors of co-location of ambulatory care with the Emergency Department along with dedicated medical and nursing staff are essential to the success of this model of care.

    2016-05-01

    Several studies have investigated the relationship between ultrasound-measured muscle thickness (MT) and individual muscle cross-sectional area (CSA) and muscle volume (MV) in extremity and trunk muscles; however, the hamstring muscle has not been studied. The purpose of this study was to examine the relationship between posterior thigh MT by ultrasound and the muscle CSA and MV of the hamstring obtained by magnetic resonance imaging (MRI). Ten young women aged 20-31 had MT measured by ultrasound at three sites on the medial anterior (50% of thigh length; TL) and posterior (50% and 70% of TL) aspects of the thigh. On the same day, a series of continuous muscle CSA along the thigh was measured by MRI. In each slice, the anatomical CSA of the hamstring (biceps femoris, semitendinosus and semimembranosus) and quadriceps muscle was analysed, and the CSAs at 50% and 70% of TL and maximal CSA of the hamstring (CSAmax ) were determined. MV was calculated by multiplying CSA by slice thickness. A significant correlation was observed between posterior 50% MT and 50% hamstring CSA (r = 0·848, P = 0·002) and between posterior 70% MT and 70% hamstring CSA (r = 0·679, P = 0·031). Posterior 50% MT (r = 0·732, P = 0·016) and 50% MTxTL (r = 0·873, P = 0·001) were also correlated to hamstring MV. Anterior:posterior 50% thigh MT ratio was correlated to MV ratio of quadriceps and hamstring muscles (r = 0·803, P = 0·005). Our results suggest that posterior thigh MT reflects hamstring muscle CSA and MV.

    2011-02-01

    Full Text Available Abstract Background Patients with COPD on long term oxygen therapy frequently do not adhere to their prescription, and they frequently do not use their ambulatory oxygen systems as intended. Reasons for this lack of adherence are not known. The aim of this study was to obtain in-depth information about perceptions and use of prescribed ambulatory oxygen systems from patients with COPD to inform ambulatory oxygen design, prescription and management. Methods A qualitative design was used, involving semi-structured face-to-face interviews informed by a grounded theory approach. Twenty-seven UK community-dwelling COPD patients using NHS prescribed ambulatory systems were recruited. Ambulatory oxygen systems comprised cylinders weighing 3.4 kg, a shoulder bag and nasal cannulae. Results Participants reported that they: received no instruction on how to use ambulatory oxygen; were uncertain of the benefits; were afraid the system would run out while they were using it (due to lack of confidence in the cylinder gauge; were embarrassed at being seen with the system in public; and were unable to carry the system because of the cylinder weight. The essential role of carers was also highlighted, as participants with no immediate carers did not use ambulatory oxygen outside the house. Conclusions These participants highlighted previously unreported problems that prevented them from using ambulatory oxygen as prescribed. Our novel findings point to: concerns with the lack of specific information provision; the perceived unreliability of the oxygen system; important carer issues surrounding managing and using ambulatory oxygen equipment. All of these issues, as well as previously reported problems with system weight and patient embarrassment, should be addressed to improve adherence to ambulatory oxygen prescription and enhance the physical and social benefits of maintaining mobility in this patient group.

    Restoring posterior teeth with resin-based composite materials continues to gain popularity among clinicians, and the demand for such aesthetic restorations is increasing. Indeed, the most common aesthetic alternative to dental amalgam is resin composite. Moderate to large posterior composite restorations, however, have higher failure rates, more recurrent caries, and increased frequency of replacement. Investigators across the globe are researching new materials and techniques that will improve the clinical performance, handling characteristics, and mechanical and physical properties of composite resin restorative materials. Despite such attention, large to moderate posterior composite restorations continue to have a clinical lifetime that is approximately one-half that of the dental amalgam. While there are numerous recommendations regarding preparation design, restoration placement, and polymerization technique, current research indicates that restoration longevity depends on several variables that may be difficult for the dentist to control. These variables include the patient’s caries risk, tooth position, patient habits, number of restored surfaces, the quality of the tooth–restoration bond, and the ability of the restorative material to produce a sealed tooth–restoration interface. Although clinicians tend to focus on tooth form when evaluating the success and failure of posterior composite restorations, the emphasis must remain on advancing our understanding of the clinical variables that impact the formation of a durable seal at the restoration–tooth interface. This paper presents an update of existing technology and underscores the mechanisms that negatively impact the durability of posterior composite restorations in permanent teeth. PMID:23750102

    To examine the prevalence, natural history, and clinical significance of high postvoid residual (PVR) volume in ambulatory older women. Prospective cohort study. Group health plan in Washington state. Nine hundred eighty-seven ambulatory women aged 55 to 75. PVR was measured using bladder ultrasonography at baseline, 1 year, and 2 years. Participants completed questionnaires about urinary symptoms and provided urine samples for microbiological evaluation. Of the 987 participants, 79% had a PVR less than 50 mL, 10% of 50 to 99 mL, 6% of 100 to 199 mL, and 5% of 200 mL or greater at baseline. Of women with a PVR less than 50 mL, 66% reported at least one urinary symptom at baseline. Of women with a PVR of 200 mL or greater, 27% reported no significant symptoms at baseline. In adjusted analyses using data from all study visits, women with a PVR of 100 mL or greater were more likely to report urinating more than eight times during the day (odds ratio (OR)=1.42, 95% confidence interval (CI)=1.07-1.87), and women with a PVR of 200 mL or greater were more likely to report weekly urgency incontinence (OR=1.50, 95% CI=1.03-2.18) than those with a PVR less than 50 mL. High PVR was not associated with greater risk of stress incontinence, nocturnal frequency, or urinary tract infection in adjusted analyses. Forty-six percent of those with a PVR of 200 mL or greater and 63% of those with a PVR of 100 to 199 mL at baseline had a PVR less than 50 mL at 2 years. More than 10% of ambulatory older women may have a PVR of 100 mL or greater, which is associated with greater risk of some urinary symptoms, but many with high PVR are asymptomatic, and high PVR frequently resolves within 2 years. Symptom-guided management of urinary symptoms may be more appropriate than PVR-guided management in this population. © 2011, Copyright the Authors.

    The prevalence of multiple chronic diseases is increasing and is a common problem for primary health care providers. This study sought to determine the patient and health system burden of multiple chronic diseases among adults in Ontario, Canada, with a focus on the ambulatory health care system (outpatient primary health care and specialist services). This population-based study used linked health administrative data from Ontario, Canada. Individuals, aged 20 years or older, who had a valid health card, were included. Validated case definitions were used to identify persons with at least one of the following nine chronic diseases: diabetes, congestive heart failure, acute myocardial infarction, stroke, hypertension, asthma, chronic obstructive lung disease, peripheral vascular disease and end stage renal failure. Prevalence estimates for chronic diseases were calculated for April 1, 2009. Ambulatory physician billing records for the two-year period, April 1, 2008 to March 31, 2010, were used to identify the number of outpatient ambulatory care visits. In 2009, 26.3% of Ontarians had one chronic disease, 10.3% had two diseases, and 5.6% had three or more diseases. Annual mean primary health care use increased significantly with each additional chronic disease. Overall, there were twice as many patient visits to primary health care providers compared to specialists across all chronic disease counts. Among those with multiple diseases, primary health care visits increased with advancing age, while specialist care dropped off. While persons with three or more diseases accounted for a disproportionate share of primary health care visits, the largest number of visits were made by those with no or one chronic disease. The burden of care for persons with multiple chronic diseases is considerable and falls largely on the primary health care provider. However persons with no or one chronic disease are responsible for the largest number of ambulatory health care visits

  19. Continuous tokamaks

    International Nuclear Information System (INIS)

    Peng, Y.K.M.

    1978-04-01

    A tokamak configuration is proposed that permits the rapid replacement of a plasma discharge in a ''burn'' chamber by another one in a time scale much shorter than the elementary thermal time constant of the chamber first wall. With respect to the chamber, the effective duty cycle factor can thus be made arbitrarily close to unity minimizing the cyclic thermal stress in the first wall. At least one plasma discharge always exists in the new tokamak configuration, hence, a continuous tokamak. By incorporating adiabatic toroidal compression, configurations of continuous tokamak compressors are introduced. To operate continuous tokamaks, it is necessary to introduce the concept of mixed poloidal field coils, which spatially groups all the poloidal field coils into three sets, all contributing simultaneously to inducing the plasma current and maintaining the proper plasma shape and position. Preliminary numerical calculations of axisymmetric MHD equilibria in continuous tokamaks indicate the feasibility of their continued plasma operation. Advanced concepts of continuous tokamaks to reduce the topological complexity and to allow the burn plasma aspect ratio to decrease for increased beta are then suggested

    The effect of clinic-based intensive hypertension treatment on ambulatory blood pressure (BP) is unknown. The goal of the Systolic Blood Pressure Intervention Trial (SPRINT) Ambulatory BP Ancillary Study was to evaluate the effect of intensive versus standard clinic-based BP targets on ambulatory BP. Ambulatory BP was obtained within 3 weeks of the 27 month study visit in 897 SPRINT participants. Intensive treatment resulted in lower clinic systolic BP (mean difference between groups = 16.0 mmHg (95% CI: 14.1 to 17.8 mmHg)), nighttime systolic BP (mean difference = 9.6 mmHg (95% CI: 7.7 to 11.5 mmHg)), daytime systolic BP (mean difference = 12.3 mmHg (95% CI: 10.6 to 13.9 mmHg)), and 24 hour systolic BP (mean difference = 11.2 mmHg (95% CI: 9.7 to 12.8 mmHg)). The night/day systolic BP ratio was similar between the intensive (0.92 ± 0.09) and standard treatment groups (0.91 ± 0.09). There was considerable lack of agreement within participants between clinic systolic BP and daytime ambulatory systolic BP with wide limits of agreement on Bland-Altman plots. In conclusion, targeting a systolic BP of less than 120 mmHg, as compared with less than 140 mmHg, resulted in lower nighttime, daytime, and 24 hour systolic BP, but did not change the night/day systolic BP ratio. Ambulatory BP monitoring may be required to assess the effect of targeted hypertension therapy on out of office BP. Further studies are needed to assess whether targeting hypertension therapy based on ambulatory BP improves clinical outcomes. PMID:27849563

    Compassion practices both recognize and reward compassion in the workplace as well as provide compassionate support to health care employees. However, these practices represent an underexplored organizational tool that may aid clinician well-being and positively impact patient ambulatory care experiences. To examine the relationship between compassion practices and nursing staff well-being and clinic-level patients' experience ratings in the ambulatory clinic setting. Surveys were collected from ambulatory nurses in January and February of 2015 in 30 ambulatory clinics affiliated with an academic medical center. Patient experience ratings were collected April to June of 2015. One hundred seventy-seven ambulatory nurses (Registered Nurses, LPNs, medical assistants), as well as 3525 adult patients from the ambulatory clinics. Ambulatory nurses assessed compassion practices, emotional exhaustion, and psychological vitality. Patient experience ratings were patient perceptions of courtesy and caring shown by nurses and patients' ratings of the outpatient services. Compassion practices are significantly and negatively associated with nurse emotional exhaustion and positively associated with nurse psychological vitality. At the clinic-level, compassion practices are significantly and positively associated with patient perceptions of caring shown by nurses and overall patient ratings of the outpatient clinic. Supplemental analyses provide preliminary evidence that nurse well-being mediates the relationship between compassion practices and patient ratings of their care experience. Our findings illustrate that compassion practices are positively associated with nurse well-being and patient perceptions of the care experience in outpatient clinics.

    The present study provided a group learning activity called "Ambulatory Medicine Tutorial-AMT" for 5th year medical students in order to facilitate learning experience at ambulatory setting and to improve medical students' clinical performance. This research aimed specifically to study the effect of AMT. Two groups of twenty 5th-year medical students were enrolled during their ambulatory medicine blocks. Each medical student was assigned to have 8 ambulatory sessions. AMT was assigned to one group while the other group only used conventional learning activity. At the end of the present study, total internal medicine scores, patient satisfaction surveys, and data on average time spent on each clinical encounter were collected and compared. The AMT group received a higher total internal medicine score as compared to the conventional group (76.2 +/- 3.6 vs. 72.9 +/- 2.8, p = 0.003). The AMT group could reduce average time spent on each clinical encounter within their first-6 ambulatory sessions while the conventional group could acquire the same skill later in their last 2 ambulatory sessions. There was no significant difference found on comparing patient satisfaction scores between the 2 groups. AMT helped improving medical students' outcomes as shown from higher total internal medicine score as well as quicker improvement during real-life clinical encounters, AMT could be a good alternative learning activity for medical students at ambulatory setting.

    The concept of day surgery is becoming an increasingly important part of elective surgery worldwide. Relentless pressure to cut costs may constrain clinical judgment regarding the most appropriate location for a patient's surgical care. The aim of this study was to determine clinical and quality indicators relating to our experience in orthopedic day durgery, mainly in relation to unplanned overnight admission and readmission rates. Additionally, we focused on describing the main characteristics of the patients that experienced complications, and compared the patient satisfaction rates following ambulatory and non-ambulatory procedures. We evaluated 10,032 patients who underwent surgical orthopedic procedures according to the protocols of our Ambulatory Surgery Unit. All complications that occurred were noted. A quality-of-life assessment (SF-36 test) was carried out both pre- and postoperatively. Ambulatory substitution rates and quality indicators for orthopedic procedures were also determined. The major complication rate was minimal, with no mortal cases, and there was a high rate of ambulatory substitution for the procedures studied. Outcomes of the SF-36 questionnaire showed significant improvement postoperatively. An unplanned overnight admission rate of 0.14 % was achieved. Our institution has shown that it is possible to provide good-quality ambulatory orthopedic surgery. There still appears to be the potential to increase the proportion of these procedures. Surgeons and anesthesiologists must strongly adhere to strict patient selection criteria for ambulatory orthopedic surgery in order to reduce complications in the immediate postoperative term.

    Currently, most patients undergoing laparoscopic cholecystectomy (LC) in Switzerland are inpatients for 2-3 days. Due to a lack of available hospital beds, we asked whether day-case surgery would be an option for patients in central Switzerland. The questions of acceptability of outpatient LC and factors contributing to the acceptability thus arose. Hundred patients suffering from symptomatic cholecystolithiasis, capable of communicating in German, and between 18 and 65 years old, were included. Patients received a pre-operative questionnaire on medical history and social situation when informed consent on surgery and participation in the study was obtained. Exclusion criteria were patients suffering from acute cholecystitis or any type of cancer; having a BMI >40 kg/m 2 ; needing conversion to open cholecystectomy or an intraoperative drainage; and non-German speakers. Surgery was performed laparoscopically. Both surgeon and patient filled in a postoperative questionnaire. The surgeon's questionnaire listed medical and technical information, and the patients' questionnaire listed medical information, satisfaction with the treatment and willingness to be released on the same day. These data from both questionnaires were grouped into social and medical factors and analysed on their influence upon willingness to accept an ambulatory procedure. No outpatient follow-up apart from checking for readmission to our hospital within 1 month after discharge was performed. Of the 100 participants, one-third was male. More than two-thirds were Swiss citizens. Only one participant was ineligible for rapid release evaluation due to need of a drainage. Among the social factors contributing to the acceptability of ambulatory care, we found nationality to be relevant; Swiss citizens preferred an inpatient procedure, whereas non-Swiss citizens were significantly more willing to return home on the same day. Household size, sex and age did not correlate with a preference for

    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.

    PURPOSE: Cardiovascular disease is prevalent among workers with high levels of occupational physical activity. The increased risk may be due to a high relative aerobic workload, possibly leading to increased blood pressure. However, studies investigating the relation between relative aerobic...... workload and ambulatory blood pressure (ABP) are lacking. The aim was to explore the relationship between objectively measured relative aerobic workload and ABP. METHODS: A total of 116 cleaners aged 18-65 years were included after informed consent was obtained. A portable device (Spacelabs 90217......) was mounted for 24-h measurements of ABP, and an Actiheart was mounted for 24-h heart rate measurements to calculate relative aerobic workload as percentage of relative heart rate reserve. A repeated-measure multi-adjusted mixed model was applied for analysis. RESULTS: A fully adjusted mixed model...

    2009-01-01

    Efforts to improve the quality of ambulatory care have received tremendous attention as bold new initiatives aimed at influencing the environment of care through financial incentives, public transparency, and information technology rapidly spread. Academic medical centers, which represent a long tradition of excellence and innovation in medical care, might be expected to lead the charge in these new arenas, but motivation for change may be mitigated by the unique complexity and multiple goals of these institutions. A survey conducted in the fall of 2006 examined the early impact of these major new influences on faculty practice plans. Respondents reported that many institutions have begun to develop key components of a quality infrastructure, but much work remains before a robust model emerges at most sites. Some academic medical centers have also embraced pay-for-performance and public reporting efforts, but many are not equipped or eager to engage in these new initiatives.

    Using ambulatory cardiac monitor (VEST) at exercise study, its time resolution is very important factor. We evaluated the time resolution of VEST using pulsate cardiac baloon phantom. Four analysis were carried out; no smoothing (NS) method, 3 points smoothing (3S) method, short sampling interval (SS) method, and digital filter (DF) method. By comparison of |ΔEF| (|EF:HR120-EF: HR60|) among 4 analysis methods, |ΔEF| by DF method was significant small (NS:3.58±3.01, 3S: 4.46±0.95, SS: 3.35±3.26, DF: 1.11±1.28%). We conclude that correction of time resolution by digital filter is necessary when we use VEST during exercise. (author)

  12. Needle phobia--changing venepuncture practice in ambulatory care.

    Needle phobia is a term used in practice to describe an anticipatory fear of needle insertion. A proportion of children display high levels of fear, pain and behavioural distress when exposed to, or anticipating, needle insertion. A difficult routine venepuncture in our ambulatory care unit led staff to review practice and develop a three-step approach to overcoming 'needle phobia': relaxation, control and graded exposure. These developments have resulted in the unit becoming a local referral centre for children and young people between the ages of 5-19 years with this problem. Time and skill are needed to prevent or overcome this distressing problem which can be caused by health care professionals not listening to children and young people.

    An observational radiographic study examining lumbar sagittal contour of patients undergoing posterior interbody arthrodesis. To compare operative alterations of lumbar sagittal contour after posterior interbody fusion using threaded interbody devices alone versus vertical cages combined with posterior compression instrumentation. Technique-related alterations of lumbar sagittal contour during interbody arthrodesis have received little attention in the spinal literature. Standing lumbar radiographs were measured for preoperative and postoperative segmental lordosis at levels undergoing posterior interbody arthrodesis using either stand-alone side-by-side threaded devices or vertical cages combined with posterior transpedicular compression instrumentation. Sagittal plane segmental correction (or loss of correction) was calculated and statistically compared. The radiographs of 30 patients (34 spinal segments) undergoing lumbar or lumbosacral arthrodesis were compared. Seventeen patients (18 segments) had undergone interbody fusion using threaded cages,whereas 13 patients (16 segments) underwent fusion using vertically oriented mesh cages combined with posterior compression instrumentation. Preoperative segmental lordosis averaged 8 degrees for both groups. For patients undergoing fusion with threaded cages, there was a mean lordotic loss of 3 degrees/segment. For patients undergoing fusion with vertically oriented mesh cages combined with posterior compression instrumentation,there was a mean lordotic gain of 5 degrees/segment. This difference in segmental sagittal plane contour was highly significant (P = 0.00). Threaded fusion devices placed under interbody distraction with the endplates parallel fail to preserve or reestablish segmental lordosis. Vertical cages, however, when combined with posterior compression instrumentation, not only maintain segmental lordosis, but also can correct sagittal plane deformity.

    A patient with intractable posterior epistaxis was treated with embolization of the ipsilateral sphenopalatine and facial arteries and contralateral sphenopalatine artery. She continued to bleed despite a seemingly adequate embolization procedure. A second angiogram revealed a significant collateral blood supply to the posterior nasal cavity from the accessory meningeal artery not identified during the first procedure. This was then embolized with no further epistaxis encountered. This case demonstrates yet another collateral arterial pathway that might account for a failed embolization

    Cough is a common symptom prompting patients to seek medical care. Like patients in the general population, patients with compromised immune systems also seek care for cough. However, it is unclear whether the causes of cough in immunocompromised patients who are deemed unlikely to have a life-threating condition and a normal or unchanged chest radiograph are similar to those in persons with cough and normal immune systems. We conducted a systematic review to answer the question: What are the most common causes of cough in ambulatory immunodeficient adults with normal chest radiographs? Studies of patients ≥ 18 years of age with immune deficiency, cough of any duration, and normal or unchanged chest radiographs were included and assessed for relevance and quality. Based on the systematic review, suggestions were developed and voted on using the American College of Chest Physicians (CHEST) methodology framework. The results of the systematic review revealed no high-quality evidence to guide the clinician in determining the likely causes of cough specifically in immunocompromised ambulatory patients with normal chest radiographs. Based on a systematic review, we found no evidence to assess whether or not the proper initial evaluation of cough in immunocompromised patients is different from that in immunocompetent persons. A consensus of the panel suggested that the initial diagnostic algorithm should be similar to that for immunocompetent persons but that the context of the type and severity of the immune defect, geographic location, and social determinants be considered. The major modifications to the 2006 CHEST Cough Guidelines are the suggestions that TB should be part of the initial evaluation of patients with cough and HIV infection who reside in regions with a high prevalence of TB, regardless of the radiographic findings, and that specific causes and immune defects be considered in all patients in whom the initial evaluation is unrevealing.

    patients' own assessment of recovery after ambulatory surgery has not been well studied. The aim was to study patients' self-assessed recovery, the occurrence and time course of post-operative problems in relation to the type of ambulatory surgery. a questionnaire was filled in by 355 patients at five time points: pre-operative, first day at home, 1, 2 and 4 weeks post-operatively. Consecutive patients who underwent either inguinal hernia repair (IHR), arthroscopic procedures (AS) or cosmetic breast augmentation (CBA) were included. unplanned return to hospital was rare (3/355). Health care contacts were noted for 9% of the patients during the first week; a total of 70 contacts occurred during the entire period. Pain was the most frequently reported symptom; 40% of the patients reported pain or mobility problems at 1 week, 28% after 2 weeks and 20% after 4 weeks. Pre-operative pain was associated with an increased level of pain during the early post-operative course, in the recovery room and at 1 week post-operatively. IHR was associated with an overall rapid recovery, while AS patients experienced a slower restitution. All AS patients who reported pain after 4 weeks had reported pain problems already pre-operatively. Pain was not present pre-operatively in the CBA group, but was common at 1 and 2 post-operative weeks and was still reported by 11% at 4 weeks. self-assessed recovery was found to cover several weeks with procedure-specific recovery patterns. Pain and mobility impairment were still frequently reported 4 weeks post-operatively. 2010 The Acta Anaesthesiologica Scandinavica Foundation.

  17. Clinical productivity of primary care nurse practitioners in ambulatory settings.

    Nurse practitioners are increasingly being integrated into primary care delivery to help meet the growing demand for primary care. It is therefore important to understand nurse practitioners' productivity in primary care practice. We examined nurse practitioners' clinical productivity in regard to number of patients seen per week, whether they had a patient panel, and patient panel size. We further investigated practice characteristics associated with their clinical productivity. We conducted cross-sectional analysis of the 2012 National Sample Survey of Nurse Practitioners. The sample included full-time primary care nurse practitioners in ambulatory settings. Multivariable survey regression analyses were performed to examine the relationship between practice characteristics and nurse practitioners' clinical productivity. Primary care nurse practitioners in ambulatory settings saw an average of 80 patients per week (95% confidence interval [CI]: 79-82), and 64% of them had their own patient panel. The average patient panel size was 567 (95% CI: 522-612). Nurse practitioners who had their own patient panel spent a similar percent of time on patient care and documentation as those who did not. However, those with a patient panel were more likely to provide a range of clinical services to most patients. Nurse practitioners' clinical productivity was associated with several modifiable practice characteristics such as practice autonomy and billing and payment policies. The estimated number of patients seen in a typical week by nurse practitioners is comparable to that by primary care physicians reported in the literature. However, they had a significantly smaller patient panel. Nurse practitioners' clinical productivity can be further improved. Copyright © 2016 Elsevier Inc. All rights reserved.

    Internal medicine is an in-hospital speciality. Along with its expertise in rare diseases, it shares with general medicine the global care of patients but its place in the ambulatory shift has yet to be defined. The objective of our work was to evaluate the benefits of an internal medicine day-hospital devoted to general medicine. Named "Centre Vi'TAL" to underline the link between the city and the hospital, this novel activity was implemented in order to respond quickly to general practitioners having difficulties to synthesize their complex patients or facing diagnostic or therapeutic problems. Using preferentially email for communication, the general practitioners can contact an internist who is committed to respond on the same day and take over the patient within 7 days if day-hospital is appropriate for his condition. The other patients are directed either to the emergency department, consultation or full hospitalization. In 14 months, the center has received 213 (144 women, 69 men) patients, mean age 53.6, addressed by 88 general practitioners for 282 day-hospital sessions. Requests included problem diagnoses (n=105), synthesis reviews for complex patients (n=65), and treatment (n=43). In the ambulatory shift advocated by the authorities, this experience shows that internal medicine should engage in the recognition of day-hospital as a place for diagnosis and synthesis reviews connected with the city while leaving the general practitioners coordinator of their patient care. This activity of synthesis in day-hospital is useful for the patients and efficient for our healthcare system. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

    Ambulatory BP monitoring (ABPM) allows a better risk stratification than office BP in hypertensive patients. However, the clinical relevance of ABPM has not been extensively investigated in the CKD population. Within the Chronic Kidney Disease Japan Cohort study, 2977 patients enrolled (62% men, aged 60.8±11.6 years) and ABPM was conducted in a subgroup of patients from September 2007 to April 2010. Data from 1075 patients (682 men) were analyzed to determine BP control and factors associated with the ABPM parameters. The prevalence of masked hypertension was 30.9%, whereas that of white-coat hypertension was 5.6%. With advancing CKD stage, the percentage of persistent hypertension increased from 21.7% to 36.1%. Diabetes, antihypertensive medicine use, and low estimated GFR (eGFR) were significantly associated with the difference between office BP and ambulatory BP (1.7 mmHg, 2.6 mmHg, and 0.6 mmHg per 10 ml/min per 1.73 m(2), respectively). There tended to be fewer nondippers and risers in stage 3 than in stages 4 and 5. In the nocturia-negative group, low eGFR, diabetes, and summer season were identified as factors associated with lower nocturnal BP change (-0.5 mmHg, -2.0 mmHg, and -2.8 mmHg, respectively). Morning BP change was greater with older age (0.2 mmHg per 10 years) and higher body mass index (0.6 mmHg per 1 kg/m(2)), and in winter (4.5 mmHg) versus summer. Various factors including eGFR, diabetes, antihypertensive medication use, and season are associated with higher BP and abnormal BP patterns in CKD patients.

    To provide weight-for-age, height-for-age, and body mass index-for-age growth reference standards for ambulatory, steroid-naïve males, ages 2-12 years, with Duchenne muscular dystrophy (DMD) and to compare these growth curves to the 2000 Centers for Disease Control and Prevention growth charts for boys, which serve as references of physical size and growth for the general male pediatric population in the US. Through a multi-state population-based surveillance of individuals with muscular dystrophy, a total of 1877 weight and 1544 height measurements ascertained during 1985-2010 from 513 males with DMD were obtained retrospectively from medical record review. Cases were classified as DMD if loss of ambulation occurred before the 12th birthday or, if younger than 12 years and still ambulating, the earliest symptoms of dystrophinopathy occurred before the 6th birthday. Each growth chart was constructed using 5 percentiles: 10th, 25th, 50th, 75th, and 90th. Smoothing procedures were applied in 2 stages to the irregular plots of the empirical percentile values. A set of growth curves, derived from a large cohort of male youth with DMD, are presented. These curves demonstrate that DMD males are shorter and tend to the extremes of weight and body mass index compared with the general male pediatric population in the US. Charts representing the pattern of growth in ambulatory, steroid-naïve males with DMD can facilitate monitoring of growth and early detection of unusual growth patterns. Use of these growth standards also will assist in monitoring responses to corticosteroid treatment. Copyright © 2013 Mosby, Inc. All rights reserved.

    In 2012, the American College of Cardiology's (ACC) Adult Congenital and Pediatric Cardiology Council established a program to develop quality metrics to guide ambulatory practices for pediatric cardiology. The council chose five areas on which to focus their efforts; chest pain, Kawasaki Disease, tetralogy of Fallot, transposition of the great arteries after arterial switch, and infection prevention. Here, we sought to describe the process, evaluation, and results of the Infection Prevention Committee's metric design process. The infection prevention metrics team consisted of 12 members from 11 institutions in North America. The group agreed to work on specific infection prevention topics including antibiotic prophylaxis for endocarditis, rheumatic fever, and asplenia/hyposplenism; influenza vaccination and respiratory syncytial virus prophylaxis (palivizumab); preoperative methods to reduce intraoperative infections; vaccinations after cardiopulmonary bypass; hand hygiene; and testing to identify splenic function in patients with heterotaxy. An extensive literature review was performed. When available, previously published guidelines were used fully in determining metrics. The committee chose eight metrics to submit to the ACC Quality Metric Expert Panel for review. Ultimately, metrics regarding hand hygiene and influenza vaccination recommendation for patients did not pass the RAND analysis. Both endocarditis prophylaxis metrics and the RSV/palivizumab metric passed the RAND analysis but fell out during the open comment period. Three metrics passed all analyses, including those for antibiotic prophylaxis in patients with heterotaxy/asplenia, for influenza vaccination compliance in healthcare personnel, and for adherence to recommended regimens of secondary prevention of rheumatic fever. The lack of convincing data to guide quality improvement initiatives in pediatric cardiology is widespread, particularly in infection prevention. Despite this, three metrics were

    Full Text Available The wnt signaling pathway is an intercellular communication mechanism essential in cell-fate specification, tissue patterning and regional-identity specification. A βcatenin-dependent signal specifies the AP (Anteroposterior axis of planarians, both during regeneration of new tissues and during normal homeostasis. Accordingly, four wnts (posterior wnts are expressed in a nested manner in central and posterior regions of planarians. We have analyzed the specific role of each posterior wnt and the possible cooperation between them in specifying and patterning planarian central and posterior regions. We show that each posterior wnt exerts a distinct role during re-specification and maintenance of the central and posterior planarian regions, and that the integration of the different wnt signals (βcatenin dependent and independent underlies the patterning of the AP axis from the central region to the tip of the tail. Based on these findings and data from the literature, we propose a model for patterning the planarian AP axis.

    Full Text Available Purpose. To report the results of the posterior pole sparing laser photocoagulation combined with intravitreal bevacizumab injection (IVB in retinopathy of prematurity (ROP. Methods. A retrospective chart review of premature babies with ROP, all of whom received laser photocoagulation with IVB. Eleven eyes of 6 infants with advanced zone I ROP underwent laser ablation sparing posterior pole with concurrent IVB. The results were compared with those of full-laser treatment combined with IVB to 8 eyes of 5 infants with advanced ROP without involvement of the posterior pole. Results. The posterior pole sparing laser with IVB was performed with zone I, stage 3+ ROP at the mean postmenstrual age of 36 weeks and 5 days. The plus sign decreased significantly at postoperative day 1, the neovascular proliferation regressed by postoperative week 1, and the normal vascularization started at postoperative day 32 on the average. Two months after treatment, vascularization of the spared avascular area was completed. There was no macular dragging, tractional retinal detachment, foveal destruction by laser scars, or any other adverse event. No significant anatomical differences were identified from those of full-laser ablation combined with IVB. Conclusions. Posterior pole sparing laser with IVB can give favorable results without destruction of posterior pole retina.

    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

    Full Text Available Christopher Kent, Julia Metzner, Laurent BollagDepartment of Anesthesiology and Pain Medicine, University of Washington Medical Center, Seattle, WA, USAAbstract: Care for patients undergoing ambulatory procedures is a broad and expanding area of anesthetic and surgical practice. There were over 35 million ambulatory surgical procedures performed in the US in 2006. Ambulatory procedures are diverse in both type and setting, as they span the range from biopsies performed under local anesthesia to intra-abdominal laparoscopic procedures, and are performed in offices, freestanding ambulatory surgery centers, and ambulatory units of hospitals. The information on adverse events from these varied settings comes largely from retrospective reviews of sources, such as quality-assurance databases and closed malpractice claims. Very few if any ambulatory procedures are emergent, and in comparison to the inpatient population, ambulatory surgical patients are generally healthier. They are still however subject to most of the same types of adverse events as patients undergoing inpatient surgery, albeit at a lower frequency. The only adverse events that could be considered to be unique to ambulatory surgery are those that arise out of the circumstance of discharging a postoperative patient to an environment lacking skilled nursing care. There is limited information on these types of discharge-related adverse events, but the data that are available are reviewed in an attempt to assist the practitioner in patient selection and discharge decision making. Among ambulatory surgical patients, particularly those undergoing screening or cosmetic procedures, expectations from all parties involved are high, and a definition of adverse events can be expanded to include any occurrence that interrupts the rapid throughput of patients or interferes with early discharge and optimal patient satisfaction. This review covers all types of adverse events, but focuses on the more

    Full Text Available A 45-year-old woman, complaining of sudden visual loss in the right eye (best-corrected visual acuity: 17/200, was suspected of having a malignant melanoma of the choroid. Fundus examination revealed a massive pale-colored subretinal mass temporal to the fovea, with adjoining choroidal folds and exudative retinal detachment. Ultrasonography was suggestive of posterior scleritis. Systemic evaluation was unremarkable. The patient was treated with high-dose systemic corticosteroids. The mass lesion resolved completely, with visual recovery to 20/20. Posterior scleritis should be suspected when evaluating subretinal mass-lesions, even when large and without overt inflammation. Early treatment may improve the visual prognosis and avoid misdirected management, including enucleation.

    Full Text Available Posterior reversible encephalopathy syndrome (PRES is characterized by the following symptoms: seizures, impaired consciousness and/or vision, vomiting, nausea, and focal neurological signs. Diagnostic imaging includes examination by magnetic resonance (MR and computed tomography (CT, where brain edema is visualized bi-laterally and symmetrically, predominantly posteriorly, parietally, and occipitally. Case report. We presented a 73-year-old patient with the years-long medical history of hipertension and renal insufficiency, who developed PRES with the symptomatology of the rear cranium. CT and MR verified changes in the white matter involving all lobes on both sides of the brain. After a two-week treatment (antihypertensive, hypolipemic and rehydration therapy clinical improvement with no complications occurred, with complete resolution of changes in the white matter observed on CT and MR. Conclusion. PRES is a reversible syndrome in which the symptoms withdraw after several days to several weeks if early diagnosis is made and appropriate treatment started without delay.

    Hemivertebrae, associated with a failure in the formation and fusion of vertebral body ossification nuclei, are a common cause of thoracic or lumbar scoliosis. A cervical location is rare and even rarer as a cause of cervical subluxation in flexion and extension (for which only one previous case has been found). We report on the case of a 7-year-old female patient, who was examined for a cervical fusion defect, consisting of a posterior C4 hemivertebra and a left hemiblock from C5 to C7. After performing surgery consisting of a C4 corpectomy and anterior fixation with intersomatic graft and plate, adequate cervical stabilization with only a self-limiting left C6 brachialgia and ipsilateral Horner syndrome occurs in the postoperative period. Posterior cervical hemivertebra associated with instability is a very rare finding. The anterior approach with corpectomy and anterior plate enables suitable stabilization.

    Full Text Available Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years. Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%. On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

  12. Unilateral spatial neglect after posterior parietal damage.

    2018-01-01

    Unilateral spatial neglect is a disabling neurologic deficit, most frequent and severe after right-hemispheric lesions. In most patients neglect involves the left side of space, contralateral to a right-hemispheric lesion. About 50% of stroke patients exhibit neglect in the acute phase. Patients fail to orient, respond to, and report sensory events occurring in the contralateral sides of space and of the body, to explore these portions of space through movements by action effectors (eye, limbs), and to move the contralateral limbs. Neglect is a multicomponent higher-level disorder of spatial awareness, cognition, and attention. Spatial neglect may occur independently of elementary sensory and motor neurologic deficits, but it can mimic and make them more severe. Diagnostic tests include: motor exploratory target cancellation; setting the midpoint of a horizontal line (bisection), that requires the estimation of lateral extent; drawing by copy and from memory; reading, assessing neglect dyslexia; and exploring the side of the body contralateral to the lesion. Activities of daily living scales are also used. Patients are typically not aware of neglect, although they may exhibit varying degrees of awareness toward different components of the deficit. The neural correlates include lesions to the inferior parietal lobule of the posterior parietal cortex, which was long considered the unique neuropathologic correlate of neglect, to the premotor and to the dorsolateral prefrontal cortices, to the posterior superior temporal gyrus, at the temporoparietal junction, to subcortical gray nuclei (thalamus, basal ganglia), and to parietofrontal white-matter fiber tracts, such as the superior longitudinal fascicle. Damage to the inferior parietal lobule of the posterior parietal cortex is specifically associated with the mainly egocentric, perceptual, and exploratory extrapersonal, and with the personal, bodily components of neglect. Productive manifestations, such as

    The reversible posterior leukoencephalopathy syndrome is a clinical/radiological syndrome characterized by headache, seizures, impaired vision, acute hypertension, and typical magnetic resonance imaging findings. There are several reports in the literature that depict its occurrence in cancer patients. The list of common anticancer and supportive care drugs that predispose to reversible posterior leukoencephalopathy syndrome is expanding and includes not only a large number of chemotherapeutic agents but also an increased number of new targeted drugs, particularly angiogenesis inhibitors such as bevacizumab,sorefenib and sunitinib. Pazopanib is an oral tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-Kit which after a positive phase III randomized clinical trial in patients with advanced renal cell cancer received FDA approval for the treatment of advanced renal cell carcinoma. Until now no cases of reversible posterior leukoencephalopathy syndrome induced by pazopanib have been reported. We present the case of a 40 years old female patient with heavily pre-treated metastatic renal cell carcinoma who received pazopanib as salvage treatment. After 21 days of pazopanib therapy the patient referred to the emergency department with epileptic seizure, impaired vision at both eyes and headache. MRI of the brain revealed subcortical oedema at the occipital and parietal lobes bilaterally. She was treated with anticonvulsants, i.v. administration of mannitol and antihypertensives and she recovered completely from her symptoms and was discharged on the tenth hospital day. A brain MRI performed 3 weeks after showed that the subcortical oedema had been subsided. In conclusion this is the first case of pazopanib induced reversible posterior leukoencephalopathy syndrome. Although usually reversible, this syndrome is a serious and potentially life threatening adverse effect, if untreated, that should

    We describe a young woman with Burkitt's lymphoma, treated with intravenous adriamycine and cyclophosphamide and intrathecal cytarabine. She developed a reversible posterior leukoencephalopathy syndrome (RPLS) with typical MRI findings. Diffusion-weighted images during the first days after the onset of symptoms predicted a small irreversible lesion in the frontal lobe, verified on T2-weighted images 1 month later. The patient showed full recovery after high-dose steroid treatment. (orig.)

    The authors report a case of thrombosis of the distal end of an enlarged right posterior epidural vein. The patient had a markedly narrow lumbar canal due to L5 spondylolisthesis. The dilated vein and the thrombosis were displayed by computed tomography but remained unrecognized until surgery. Pathogenesis of this condition is discussed. A review of the English, French and German literature revealed no prior radiological reports of a similar condition.

    The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years). Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%). On control examinations, there was no finding of instability or cervical kyphosis. Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

    Full Text Available Background: Fracture of the posterior wall is the most common pattern in acetabular fractures. The anatomical reduction and stable fixation of this articular fracture is a prerequisite for a favorable functional outcome but it is not enough in itself. In some patients, even physical therapy with initial passive motion and continued active exercises without weight bearing could lead to excessive loading on the injured cartilage and, in some cases, even to dislocation of fragments and early post-traumatic osteoarthritis. Our biomechanical studies demonstrated high loading of the acetabulum even during standard physical therapy.Case report: This article describes, using these mathematical models, a patient in whom a secondary dislocation of the fragments of the posterior wall occurred due to involuntary fast movements of the hip after surgical fixation. We have found that absolute values of hip joint reaction force and peak contact hip stress depend on the speed of movement and the angle of abductin and are significantly higher than during full weight bearing.Conclusions: We recommends to avoid fast movements and isometric exercises in early postoperative period.

    Full Text Available A premature male infant was born at 30 weeks’ gestation with a birth weight of 1,700 g in a rural hospital. He was diagnosed with respiratory distress syndrome and received continuous positive airway pressure treatment for 26 days. At 26 days after birth, the patient was transferred to our hospital for further evaluation and management. A comprehensive eye examination revealed a stage 3 retinopathy of prematurity (ROP involving zone 2 in both eyes. The patient was recommended to a provincial-level eye hospital for emergency laser therapy. Five months after birth, the feedback from the eye hospital showed that the patient had a high risk of blindness in both eyes. Our case report shows that delaying first screening examination increases the possibility of developing aggressive posterior ROP in infants with ROP. Doctors in rural hospitals should be aware of this possibility and trained for early screening and treatment in high-risk infants.

    The effectiveness of exercise to lower blood pressure may depend on the type and intensity of exercise. We study the short-term (i.e., 14-h) effects of a bout of high-intensity aerobic interval training (HIIT) on blood pressure in metabolic syndrome (MetS) patients. Nineteen MetS patients (55.2 ± 7.3 years, 6 women) entered the study. Eight of them were normotensive and eleven hypertensive according to MetS threshold (≥130 mmHg for SBP and/or ≥85 mmHg for DBP). In the morning of 3 separated days, they underwent a cycling exercise bout of HIIT (>90% of maximal heart rate, ~85% VO 2max ), or a bout of isocaloric moderate-intensity continuous training (MICT; ~70% of maximal heart rate, ~60% VO 2max ), or a control no-exercise trial (REST). After exercise, ambulatory blood pressure (ABP; 14 h) was monitored, while subjects continued their habitual daily activities wearing a wrist-band activity monitor. No ABP differences were found for normotensive subjects. In hypertensive subjects, systolic ABP was reduced by 6.1 ± 2.2 mmHg after HIIT compared to MICT and REST (130.8 ± 3.9 vs. 137.4 ± 5.1 and 136.4 ± 3.8 mmHg, respectively; p HIIT exercise bout is superior to an equivalent bout of continuous exercise when used as a non-pharmacological aid in the treatment of hypertension in MetS.

    Full Text Available Objectives To determine whether there are differences in pressure and flow measurements between conventional cystometry (CONV and ambulatory urodynamic monitoring (AMB in women with overactive bladder syndrome and urinary incontinence. Materials and Methods Retrospective study which included female subjects who underwent both CONV (with saline filling medium and AMB, separated by less than 24 months, not using medication active on the lower urinary tract and without history of prior pelvic surgery. Both tests were carried out in compliance with the International Continence Society standards. The paired Student’s t test was used to compare continuous variables. Bland-Altman statistics were used to assess the agreement of each variable between both studies. Results Thirty women with a median (range age of 50 (14 - 73 years met the inclusion criteria. AMB was carried out at a mean (SD of 11 (6 months after CONV. Measurements of pves and pabd at the end of filling, and Qmax were significantly higher from AMB recordings. There were no differences in pdet at the end of filling, pdetQmax or pdetmax during voiding, nor significant difference in Vvoid. Conclusions We provide previously undocumented comparative voiding data between CONV and AMB for patients who most commonly require both investigations. Our findings show higher values of Qmax but similar values of pdetQmax measured by AMB which may partly reflect an overall lower catheter caliber, physiological filling but perhaps also more ‘normal’ voiding conditions.

    Radical innovation and disruptive technologies are frequently heralded as a solution to delivering higher quality, lower cost health care. According to the literature on disruption, local hospitals and physicians (incumbent providers) may be unable to competitively respond to such "creative destruction" and alter their business models for a host of reasons, thus threatening their future survival. However, strategic management theory and research suggest that, under certain conditions, incumbent providers may be able to weather the discontinuities posed by the disrupters. This article analyzes 3 disruptive innovations in service delivery: single-specialty hospitals, ambulatory surgical centers, and retail clinics. We first discuss the features of these innovations to assess how disruptive they are. We then draw on the literature on strategic adaptation to suggest how incumbents develop competitive responses to these disruptive innovations that assure their continued survival. These arguments are then evaluated in a field study of several urban markets based on interviews with both incumbents and entrants. The interviews indicate that entrants have failed to disrupt incumbent providers primarily as a result of strategies pursued by the incumbents. The findings cast doubt on the prospects for these disruptive innovations to transform health care.

    The blood pressure (BP) burden is high in pediatric hemodialysis (HD) patients and adversely affects prognosis. The aim of this study was to examine whether 44-h ambulatory BP monitoring (ABPM) provides additional relevant BP data compared with 24-h ABPM. ABPM was initiated at the end of the mid-week dialysis run in 13 stable pediatric HD patients and continued until the next run for 44 h. Day 1 was defined as the initial 24-h ABPM and Day 2 as the time period after that until the next dialysis run. All patients had an echocardiogram to calculate the left ventricular mass index (LVMI). A higher percentage of patients were diagnosed with hypertension from the 44-h ABPM than from the 24-h ABPM. All BP indexes and loads (except nighttime diastolic load) were significantly higher on Day 2 than on Day 1. Patients with BP loads of ≥ 25 % on 44-h ABPM had significantly higher LVMI than those patients with normal BP loads. No such association was found with 24-h ABPM and LVMI. Higher interdialytic weight gain was associated with higher Day-2 nighttime systolic BP load. The 44-h ABPM provides more information than the 24-h ABPM in terms of diagnosing and assessing the true burden of hypertension in pediatric HD patients. Elevated BP loads from 44-h ABPM correlate with a higher LVMI on the echocardiogram.

    Recent guidelines have widened clinical indications for out-of-office blood pressure measurement, including home blood pressure monitoring and ambulatory blood pressure monitoring (ABPM), suggesting the latter as recommended method in cognitively impaired patients. There is, however, a widespread belief that ABPM could be poorly tolerated in dementia, often leading to withdraw from its use in these patients. To assess the actual tolerability of ABPM in a group of cognitively impaired elderly, affected by dementia or mild cognitive impairment (MCI). We evaluated 176 patients aged 65 + years, recruited in two different memory clinics, with a Mini Mental State Examination (MMSE) between 10 and 27. Behavioral and psychological symptoms were assessed with Neuropsychiatric Inventory (NPI). A patient was considered tolerant if able to keep the device on continuously for 24 h. The minimum number of correct measurements required was 70% of the predicted total number. 16% of patients wore the device for less than 24 h. Dividing the study population in tertiles of MMSE performance, 29% failed to tolerate the device in the lowest, 12% in the middle and 7% in the highest tertile (p ABPM proved a generally well-tolerated technique even in cognitively impaired elderly. Only a minority of subjects with poorer cognitive performances and greater behavioral symptoms did not tolerate the monitoring. Among most patients who failed to achieve the minimum number of measurements needed, the number of valid measurements was very close to the minimum required.

    Anesthesia information management systems (AIMS) are increasingly being implemented throughout the United States. However, little information exists on the implementation process for AIMS within ambulatory surgery centers (ASC). The objectives of this descriptive study are to document: 1) the phases of implementation of an AIMS at an ASC; and 2) lessons learnt from a socio-technical perspective. The ASC, within the Veterans Health Administration (VHA), has hosted an AIMS since 2008. As a quality improvement effort, we implemented a new version of the AIMS. This new version involved fundamental software changes to enhance clinical care such as real-time importing of laboratory data and total hardware exchange. The pre-implementation phase involved coordinated preparation over six months between multiple informatics teams along with local leadership. During this time, we conducted component, integration, and validation testing to ensure correct data flow from medical devices to AIMS and centralized databases. The implementation phase occurred in September 2014 over three days and was successful. Over the next several months, during post-implementation phase, we addressed residual items like latency of the application. Important lessons learnt from the implementation included the utility of partnering early with executive leadership; ensuring end user acceptance of new clinical workflow; continuous testing of data flow; use of a staged rollout; and providing additional personnel throughout implementation. Implementation of an AIMS at an ASC can utilize methods developed for large hospitals. However, issues unique to an ASC such as limited number of support personnel and distinctive workflows must be considered.

  11. [Ambulatory blood pressure monitoring is a useful tool for all patients].

    Science.gov (United States)

    de la Sierra, A

    Clinical blood pressure measurement (BP) is an occasional and imperfect way of estimating this biological variable. Ambulatory blood pressure monitoring (ABPM) is by far the best clinical tool for measuring an individual's blood pressure. Mean values over 24h, through the daytime and at night all make it more possible to predict organic damage and the future development of the disorder. ABPM enables the detection of white-coat hypertension and masked hypertension in both the diagnosis and follow-up of treated patients. Although some of the advantages of ABPM can be reproduced by more automated measurement without the presence of an observer in the clinic or self-measurement at home, there are some other elements of great interest that are unique to ABPM, such as seeing what happens to a patient's BP at night, the night time dipping pattern and short-term variability, all of which relate equally to the patient's prognosis. There is no scientific or clinical justification for denying these advantages, and ABPM should form part of the evaluation and follow-up of practically all hypertensive patients. Rather than continuing unhelpful discussions as to its availability and acceptability, we should concentrate our efforts on ensuring its universal availability and clearly explaining its advantages to both doctors and patients.

    2012-01-01

    Ambulatory care settings employ 25% of the three million registered nurses in the United States. The American Academy of Ambulatory Care Nursing (AAACN) is committed to improving the quality of health care in ambulatory settings, enhancing patient outcomes, and realizing greater health care efficiencies. A survey of ambulatory care registered nurses indicates they are well positioned to lead and facilitate health care reform activities with organizational colleagues. They are well schooled in critical thinking, triage, advocating for patients, educating patients and families, collaborating with medical staff and other professionals, and care coordination. The evolving medical home concept and other health care delivery models reinforces the critical need for registered nurses to provide chronic disease management, care coordination, health risk appraisal, care transitions, health promotion, and disease prevention services. Recommendations are offered for organizational leaders, registered nurses, and AAACN to utilize nursing knowledge and skills in the pursuit of leading change and advancing health.

    To describe work environment characteristics (leadership style and safety climate) of ambulatory surgical settings and to examine the relationship between work environment and nurses' willingness to report medication errors in ambulatory surgical settings. Descriptive correlational design using survey methodology. The sample of this study consisted of 40 unit-based registered nurses, working as full time, part time, or as needed in four ambulatory surgical settings affiliated with one health care system located in Northeast Ohio. The results of two separate regression analyses, one with three nurse manager's leadership styles and another with five safety climate dimensions as independent variables, explained 44% and 50%, respectively, on variance of nurses' willingness to report medication errors. To increase nurses' willingness to report medication errors, ambulatory surgical settings administrators should invest in nurse manager leadership training programs and focus on enhancing safety climate aspects, particularly errors feedback and organizational learning.

  1. Twenty-Four-Hour Ambulatory Blood Pressure Monitoring in Hypertension

    Science.gov (United States)

    2012-01-01

    Executive Summary Objective The objective of this health technology assessment was to determine the clinical effectiveness and cost-effectiveness of 24-hour ambulatory blood pressure monitoring (ABPM) for hypertension. Clinical Need: Condition and Target Population Hypertension occurs when either systolic blood pressure, the pressure in the artery when the heart contracts, or diastolic blood pressure, the pressure in the artery when the heart relaxes between beats, are consistently high. Blood pressure (BP) that is consistently more than 140/90 mmHg (systolic/diastolic) is considered high. A lower threshold, greater than 130/80 mmHg (systolic/diastolic), is set for individuals with diabetes or chronic kidney disease. In 2006 and 2007, the age-standardized incidence rate of diagnosed hypertension in Canada was 25.8 per 1,000 (450,000 individuals were newly diagnosed). During the same time period, 22.7% of adult Canadians were living with diagnosed hypertension. A smaller proportion of Canadians are unaware they have hypertension; therefore, the estimated number of Canadians affected by this disease may be higher. Diagnosis and management of hypertension are important, since elevated BP levels are related to the risk of cardiovascular disease, including stroke. In Canada in 2003, the costs to the health care system related to the diagnosis, treatment, and management of hypertension were over $2.3 billion (Cdn). Technology The 24-hour ABPM device consists of a standard inflatable cuff attached to a small computer weighing about 500 grams, which is worn over the shoulder or on a belt. The technology is noninvasive and fully automated. The device takes BP measurements every 15 to 30 minutes over a 24-to 28-hour time period, thus providing extended, continuous BP recordings even during a patient’s normal daily activities. Information on the multiple BP measurements can be downloaded to a computer. The main detection methods used by the device are auscultation and

    Full Text Available Programs with control are usually modeled using lambda calculus extended with control operators. Instead of modifying lambda calculus, we consider a different model of computation. We introduce continuation calculus, or CC, a deterministic model of computation that is evaluated using only head reduction, and argue that it is suitable for modeling programs with control. It is demonstrated how to define programs, specify them, and prove them correct. This is shown in detail by presenting in CC a list multiplication program that prematurely returns when it encounters a zero. The correctness proof includes termination of the program. In continuation calculus we can model both call-by-name and call-by-value. In addition, call-by-name functions can be applied to call-by-value results, and conversely.

    The effect of clinic-based intensive hypertension treatment on ambulatory blood pressure (BP) is unknown. The goal of the SPRINT (Systolic Blood Pressure Intervention Trial) ambulatory BP ancillary study was to evaluate the effect of intensive versus standard clinic-based BP targets on ambulatory BP. Ambulatory BP was obtained within 3 weeks of the 27-month study visit in 897 SPRINT participants. Intensive treatment resulted in lower clinic systolic BP (mean difference between groups=16.0 mm Hg; 95% confidence interval, 14.1-17.8 mm Hg), nighttime systolic BP (mean difference=9.6 mm Hg; 95% confidence interval, 7.7-11.5 mm Hg), daytime systolic BP (mean difference=12.3 mm Hg; 95% confidence interval, 10.6-13.9 mm Hg), and 24-hour systolic BP (mean difference=11.2 mm Hg; 95% confidence interval, 9.7-12.8 mm Hg). The night/day systolic BP ratio was similar between the intensive (0.92±0.09) and standard-treatment groups (0.91±0.09). There was considerable lack of agreement within participants between clinic systolic BP and daytime ambulatory systolic BP with wide limits of agreement on Bland-Altman plots. In conclusion, targeting a systolic BP of hypertension therapy on out of office BP. Further studies are needed to assess whether targeting hypertension therapy based on ambulatory BP improves clinical outcomes. URL: http://www.clinicaltrials.gov.

    The current evidence suggests that ambulatory blood pressure monitoring (ABPM) should be an integral part of the diagnosis and management of hypertension. However, its uptake in routine clinical practice has been variable. This paper reviews the current evidence for the role of ABPM in clinical practice, including in hypotensive disorders and in specific comorbidities. It further discusses the clinical significance of abnormal ambulatory blood pressure patterns and hypertensive syndromes such as white coat, masked and resistant hypertension.

    Full Text Available Bupropion (BUP, a substituted phenyl-ethylamine, has been utilized for the treatment of depression and for smoking cessation, however, one concern is that BUP may increase a risk of psychosis similar to other substituted phenyl-ethylamine amphetamine (AMPH and methamphetamine (MetAMPH. BUP promotes ambulation in mice and causes behavioral sensitization on the ambulation-promoting effect when repeatedly administered as well as AMPH and MetAMPH. The present study aimed to elucidate brain regions and monoaminergic neurotransmitters that are involved in the ambulation-promoting effect of BUP. c-Fos-like immunoreactivity (c-Fos-IR mapping in brain in combination with measuring ambulatory activity was conducted to determine brain region(s that is involved in the ambulatory effect of BUP. Three kinds of statistical analyses for c-Fos-IR in 24 brain regions consistently showed that c-Fos-IR in the Caudate putamen (CPu is positively correlated with the ambulatory response to BUP. In addition, multiple regression analysis indicated that the ambulatory response is a function of c-Fos-IR not only in the CPu but also in the lateral septum nucleus (LS, median raphe nucleus (MnR, lateral globus pallidus (LGP, medial globus pallidus (MGP, locus coeruleus (LC and ventral hypothalamic nucleus (VMH. Effects of BUP on monoaminergic neurotransmitters in the CPu were examined using in vivo microdialysis method, as the pharmacological experiments indicated that monoaminergic neurotransmitters, dopamine (DA in particular, mediate the ambulatory response to BUP. Response of DA in the CPu to BUP was parallel to the ambulatory response, showing that DA in the CPu is involved in the ambulatory response to BUP. The present study also suggests that other brain regions such as the LC, the origin nucleus of norepinephrine (NE neurons, and another neurotransmitter NE may also play some roles for the ambulatory response to BUP, however, further studies are needed to elucidate

    Sex-related differences in systemic hemodynamics were analyzed by means of cardiac index and systemic vascular resistance according to the level of daytime ambulatory blood pressure. In addition, we assessed the relations between ambulatory blood pressure measurements and systemic hemodynamics in male and female patients. We prospectively included 52 women and 53 men referred to our unit for evaluation of arterial hypertension. Women and men were grouped according to the level of daytime mean arterial pressure: or = 110 mm Hg. Patients underwent noninvasive evaluation of resting hemodynamics (impedance cardiography) and 24-hour ambulatory blood pressure monitoring. Compared with women men with lower daytime blood pressure had a 12% higher systemic vascular resistance index (P = NS) and a 14% lower cardiac index (P < .02), whereas men with higher daytime blood pressure had a 25% higher vascular resistance (P < .003) and a 21% lower cardiac index (P < .0004). Furthermore, in men systemic vascular resistance correlated positively with both daytime and nighttime systolic and diastolic blood pressures, whereas cardiac index correlated negatively only with daytime diastolic blood pressure. In contrast, women did not exhibit any significant correlation between hemodynamic parameters and ambulatory blood pressure measurements. In conclusion, sex-related differences in systemic hemodynamics were more pronounced in the group with higher daytime hypertension. The relations between systemic hemodynamics and ambulatory blood pressure level depended on the sex of the patient. In men a progressive circulatory impairment underlies the increasing level of ambulatory blood pressure, but this was not observed in women.

    Obesity in adults has been related to hypertension and abnormal nocturnal dipping of blood pressure, which are associated with poor cardiovascular and renal outcomes. Here, we aimed to resolve the relationship between the degree of obesity, the severity of hypertension and dipping status on ambulatory blood pressure in obese children. A total 72 patients with primary obesity aged 7 to 18 years (mean: 13.48 ± 3.25) were selected. Patients were divided into three groups based on body mass index (BMİ) Z-score. Diagnosis and staging of ambulatory hypertension based on 24-h blood pressure measurements, obtained from ambulatory blood pressure monitoring. Based on our ambulatory blood pressure data, 35 patients (48.6%) had hypertension, 7 (20%) had ambulatory prehypertension, 21 (60%) had hypertension, and 7 patients (20%) had severe ambulatory hypertension. There was a significant relationship between severity of hypertension and the degree of obesity (p lood pressure results and loads were similar between groups. Diastolic and mean arterial blood pressure levels during the night, diastolic blood pressure loads, and heart rate during the day were significantly higher in Group 3 (p lood pressure at night, mean arterial pressure at night, diastolic blood pressure loads and heart rate at day. Increase in BMI Z-score does not a significant impact on daytime blood pressure and nocturnal dipping status.

  11. Posterior ventricular anchoring neochordal repair of degenerative mitral regurgitation efficiently remodels and repositions posterior leaflet prolapse†

    Woo, Y. Joseph; MacArthur, John W.

    2013-01-01

    OBJECTIVES Mitral valve repair techniques for degenerative disease typically entail leaflet resection or neochordal construction, which may require extensive resection, leaflet detachment/reattachment, reliance on diseased native chords or precise neochordal measuring. Occasionally, impaired leaflet mobility, reduced coaptation surface and systolic anterior motion (SAM) may result. We describe a novel technique for addressing posterior leaflet prolapse/flail, which both simplifies repair and addresses these issues. METHODS Fifty-four patients (age 62 ± 11 years) with degenerative MR underwent this new repair, 36 of whom minimally-invasively. A CV5 Gore-Tex suture was placed into the posterior left ventricular myocardium underneath the prolapsing segment as an anchor. This suture was then used to imbricate a portion of the prolapsed segment into the ventricle, creating a smooth, broad, non-prolapsed coapting surface on a leaflet with preserved mobility, additional neochordal support and posteriorly positioned enough to preclude SAM. RESULTS Repair was successful in all patients. The mean MR grade was reduced from +3.8 to +0.1 with 50 of 54 patients having zero MR and 4 of the 54 having trace or mild MR. All patients had proper antero-posterior location of the coaptation line of a mean length of 10.2 mm, and preserved posterior leaflet mobility. No patients had SAM or mitral stenosis. All patients were discharged and are currently doing well. CONCLUSION This new technique facilitated efficient single-suture repair of the prolapsed posterior leaflet mitral regurgitation without the need for resection or sliding annuloplasty. It precluded the need for precise neochordal measurement and preserved the leaflet coaptation surface. PMID:23449863

    MRI is a useful tool to complement US for imaging of the fetal posterior fossa (PF). In France, the discovery of a PF malformation in the fetus frequently leads to termination of pregnancy (80% in a personal series). However, despite improved accuracy in the diagnosis of PF abnormalities, prognosis remains uncertain. The first objective of this review is to document the normal MRI landmarks of the developing fetal PF. Because of their thinness, the visibility of the cerebellar fissures is dramatically delayed on MRI compared to macroscopic data. An important landmark is identification of the primary fissure of the vermis, normally seen at around 25-26 weeks' gestation (WG) on the sagittal slice, separating the larger posterior lobe from the anterior lobe (volume ratio around 2:1). The prepyramidal and secondary fissures are usually only identifiable after 32 WG and the hemispheric fissures are difficult to see until the end of pregnancy. Considering the signal changes, high signal on T2-weighted (T2-W) sequences is seen from 25 WG in the posterior part of the brain stem (tegmentum and ascending sensory tracts) related to myelination. The low signal intensities seen within the cerebellum on T2-W images correspond to high cellularity of grey matter (deep nuclei), as there is no myelination within the white matter before 38 WG. The second objective is to highlight the signs highly predictive of a poor neurological prognosis. Lack of pontine curvature or vermian agenesis without a PF cyst (small volume of PF) is greatly associated with poor neurological status. The third objective is to propose a diagnostic strategy in difficult cases where prognosis is important, e.g. the Dandy Walker continuum. (orig.)

    High-grade L5-S1 spondylolisthesis alters sagittal spinopelvic balance, which can cause low back pain and progressive neurologic disorder. The present study assessed spondylolisthesis reduction and maintenance over time with L4-S1 versus L5-S1 fusion using a lever-arm system and posterior fusion combined with lumbosacral graft. Forty patients were operated on for symptomatic high-grade spondylolisthesis, 34 of whom had full pre- and post-operative radiological analysis, with a mean follow-up of 5.4years. There were 9 L5-S1 and 25 L4-S1 instrumentations. Analysis of spinopelvic and slipping parameters and the evolution of segmental lordosis compared results between L5-S1 and L4-S1 instrumentation. Mean Taillard spondylolisthesis index decreased from 64% to 37% (P=0.0001). Overall sagittal spinopelvic balance was not significantly changed. Overall L1-S1 and segmental L4-L5 lordosis were not affected by instrumentation. Mean L5-S1 segmental lordosis increased from 11° to 18°. There was loss of reduction from 19° to 14° with L5-S1 instrumentation, in contrast to maintained reduction with L4-S1 instrumentation (P=0.006). The lever-arm system provided anterior-posterior reduction of spondylolisthesis and corrected slippage. Postoperative change in overall sagittal spinopelvic balance was slight and constant. Posterior L4-S1 fusion provided better long-term control of L5-S1 lordosis reduction than the shorter L5-S1 fusion. Retrospective study of level IV. Copyright © 2014 Elsevier Masson SAS.

    Full Text Available Background/Aim. Posterior breast cancers are located in the prepectoral region of the breast. Owing to this distinctive anatomical localization, physical examination and mammographic or ultrasonographic evaluation can be difficult. The purpose of the study was to assess possibilities of diagnostic mammography and breast ultrasonography in detection and differentiation of posterior breast cancers. Methods. The study included 40 women with palpable, histopathological confirmed posterior breast cancer. Mammographic and ultrasonographic features were defined according to Breast Imaging Reporting and Data System (BI-RADS lexicon. Results. Based on standard two-view mammography 87.5%, of the cases were classified as BI-RADS 4 and 5 categories, while after additional mammographic views all the cases were defined as BIRADS 4 and 5 categories. Among 96 mammographic descriptors, the most frequent were: spiculated mass (24.0%, architectural distortion (16.7%, clustered microcalcifications (12.6% and focal asymmetric density (12.6%. The differentiation of the spiculated mass was significantly associated with the possibility to visualize the lesion at two-view mammography (p = 0.009, without the association with lesion diameter (p = 0.083 or histopathological type (p = 0.055. Mammographic signs of invasive lobular carcinoma were significantly different from other histopathological types (architectural distortion, p = 0.003; focal asymmetric density, p = 0.019; association of four or five subtle signs of malignancy, p = 0.006. All cancers were detectable by ultrasonography. Mass lesions were found in 82.0% of the cases. Among 153 ultrasonographic descriptors, the most frequent were: irregular mass (15.7%, lobulated mass (7.2%, abnormal color Doppler signals (20.3%, posterior acoustic attenuation (18.3%. Ultrasonographic BI-RADS 4 and 5 categories were defined in 72.5% of the cases, without a significant difference among various histopathological types (p = 0

    Full Text Available Interspinous spacers were developed to treat local deformities such as degenerative spondylolisthesis. To treat patients with chronic instability, posterior pedicle fixation and rod-based dynamic stabilization systems were developed as alternatives to fusion surgeries. Dynamic stabilization is the future of spinal surgery, and in the near future, we will be able to see the development of new devices and surgical techniques to stabilize the spine. It is important to follow the development of these technologies and to gain experience using them. In this paper, we review the literature and discuss the dynamic systems, both past and present, used in the market to treat lumbar degeneration.

    The patient was a 25-year-old male college student with a chief complaint of right shoulder pain. The patient was initially diagnosed with bicipital tendinitis by his physician and had been treated for 4 weeks by a physical therapist. However, his symptoms did not improve and he was unable to return to his preinjury activity levels, so he sought the services of another physical therapist for a second opinion. Due to concern for a labrum tear, the physical therapist referred the patient to an orthopaedic surgeon. Magnetic resonance arthrography revealed findings consistent with a superior labrum anterior-to-posterior tear.

    Continuous monitoring of blood pressure in daily life could improve early detection of cardiovascular disorders, as well as promoting healthcare. Conventional ambulatory blood pressure monitoring (ABPM) equipment can measure blood pressure at regular intervals for 24 hours, but is limited by long measuring time, low sampling rate, and constrained measuring posture. In this paper, we demonstrate a new method for continuous real-time measurement of blood pressure during daily activities. Our method is based on blood pressure estimation from pulse wave velocity (PWV) calculation, which formula we improved to take into account changes in the inner diameter of blood vessels. Blood pressure estimation results using our new method showed a greater precision of measured data during exercise, and a better accuracy than the conventional PWV method.

    In this article, we investigate the diversity of healthcare delivery organizations by comparing the market determinants of hospitals entry rates with those of ambulatory surgery centers (ASCs). Unlike hospitals, ASCs is one of the growing populations of specialized healthcare delivery organizations. There are reasons to believe that firm entry patterns differ within growing organizational populations since these markets are characterized by different levels of organizational legitimacy, technological uncertainty, and information asymmetry. We compare the entry patterns of firms in a mature population of hospitals to those of firms within a growing population of ASCs. By using patient-level datasets from the state of Florida, we break down our explanatory variables by facility type (ASC vs. hospital) and utilize negative binomial regression models to evaluate the impact of niche density on ASC and hospital entry. Our results indicate that ASCs entry rates is higher in markets with overlapping ASCs while hospitals entry rates are less in markets with overlapping hospitals and ASCs. These results are consistent with the notion that firms in growing populations tend to seek out crowded markets as they compete to occupy the most desirable market segments while firms in mature populations such as general hospitals avoid direct competition. © The Author(s) 2013 Reprints and permissions:]br]sagepub.co.uk/journalsPermissions.nav.

    2001-07-01

    To examine advantages of and obstacles to electronic prescribing in the ambulatory care environment. MEDLINE and International Pharmaceutical Abstract searches were conducted for the period from January 1980 to September 2000. Key words were electronic prescribing, computerized physician order entry, prior authorization, drug utilization review, and consumer satisfaction. In September 2000, a public search engine (www.google.com) was used to find additional technical information. In addition, pertinent articles were cross-referenced to identify other resources. Articles, symposia proceedings, and organizational position statements published in the United States on electronic prescribing and automation in healthcare are cited. Electronic prescribing can eliminate the time gap between point of care and point of service, reduce medication errors, improve quality of care, and increase patient satisfaction. Considerable funding requirements, segmentation of healthcare markets, lack of technology standardization, providers' resistance to change, and regulatory indecisiveness create boundaries to the widespread use of automated prescribing. The potential solutions include establishing a standardizing warehouse or a router and gaining stakeholder support in implementation of the technology. Electronic prescribing can provide immense benefits to healthcare providers, patients, and managed care. Resolution of several obstacles that limit feasibility of this technology will determine its future.

    This study's objective was to evaluate quantitative electromyography (QEMG) using multiple-motor-unit (multi-MUP) analysis in Duchenne muscular dystrophy (DMD). Ambulatory DMD boys, aged 5-15 years, were evaluated with QEMG at 6-month intervals over 14 months. EMG was performed in the right biceps brachii (BB) and tibialis anterior (TA) muscles. Normative QEMG data were obtained from age-matched healthy boys. Wilcoxon signed-rank tests were performed. Eighteen DMD subjects were enrolled, with a median age of 7 (interquartile range 7-10) years. Six-month evaluations were performed on 14 subjects. QEMG showed significantly abnormal mean MUP duration in BB and TA muscles, with no significant change over 6 months. QEMG is a sensitive electrophysiological marker of myopathy in DMD. Preliminary data do not reflect a significant change in MUP parameters over a 6-month interval; long-term follow-up QEMG studies are needed to understand its role as a biomarker for disease progression.

    Full Text Available Corey Collins Massachusetts Eye and Ear Infirmary, Department of Anesthesiology, Harvard Medical School, Boston, MA, USA Abstract: Pediatric tonsillectomy is a common surgery around the world. Surgical indications are obstructive sleep apnea and recurrent tonsillitis. Despite the frequency of tonsillectomy in children, most aspects of perioperative care are supported by scant evidence. Recent guidelines provide important recommendations although clinician adherence or awareness of published guidance is variable and inconsistent. Current guidelines establish criteria for screening children for post-tonsillectomy observation, though most are based on low-grade evidence or consensus. Current recommendations for admission are: age <3 years; significant obstructive sleep apnea; obesity; and significant comorbid medical conditions. Recent reports have challenged each criterion and recommend admission criteria that are based on clinically relevant risks or observed clinical events such as adverse respiratory events in the immediate recovery period. Morbidity and mortality are low though serious complications occur regularly and may be amenable to improvements in postoperative monitoring, improved analgesic regimens, and parental education. Careful consideration of risks attributable to individual patients is vital to determine overall suitability for ambulatory discharge.

    Although hope is a pervasive concept in cancer treatment, we know little about how ambulatory patients with cancer define or experience hope. We explored hope through semistructured interviews with ten patients with advanced (some curable, some incurable) colon cancer at one Midwestern, university-based cancer center. We conducted a thematic analysis to identify key concepts related to patient perceptions of hope. Although we did ask specifically about hope, patients also often revealed their hopes in response to indirect questions or by telling stories about their cancer experience. We identified four major themes related to hope: 1) hope is essential, 2) a change in perspective, 3) the content of hope, and 4) communicating about hope. The third theme, the content of hope, included three subthemes: a) the desire for normalcy, b) future plans, and c) hope for a cure. We conclude that hope is an essential concept for patients undergoing treatment for cancer as it pertains to their psychological well-being and quality of life, and hope for a cure is not and should not be the only consideration. In a clinical context, the exploration of patients' hopes and aspirations in light of their cancer diagnosis is important because it provides a frame for understanding their goals for treatment. Exploration of the content of patients' hope can not only help to illuminate misunderstandings but also clarify how potential treatments may or may not contribute to achieving patients' goals.

    Full Text Available Introduction: Many emergency department (ED patients have symptoms that may be attributed to arrhythmias, necessitating outpatient ambulatory cardiac monitoring. Consensus is lacking on the optimal duration of monitoring. We describe the use of a novel device applied at ED discharge that provides continuous prolonged cardiac monitoring. Methods: We enrolled discharged adult ED patients with symptoms of possible cardiac arrhythmia. A novel, single use continuous recording patch (Zio®Patch was applied at ED discharge. Patients wore the device for up to 14 days or until they had symptoms to trigger an event. They then returned the device by mail for interpretation. Significant arrhythmias are defined as: ventricular tachycardia (VT ≥4 beats, supraventricular tachycardia (SVT ≥4 beats, atrial fibrillation, ≥3 second pause, 2nd degree Mobitz II, 3rd degree AV Block, or symptomatic bradycardia. Results: There were 174 patients were enrolled and all mailed back their devices. The average age was 52.2 (± 21.0 years, and 55% were female. The most common indications for device placement were palpitations 44.8%, syncope 24.1% and dizziness 6.3%. Eighty-three patients (47.7% had ≥1 arrhythmias and 17 (9.8% were symptomatic at the time of their arrhythmia. Median time to first arrhythmia was 1.0 days (IQR 0.2-2.8 and median time to first symptomatic arrhythmia was 1.5 days (IQR 0.4-6.7. 93 (53.4% of symptomatic patients did not have any arrhythmia during their triggered events. The overall diagnostic yield was 63.2% Conclusion: The Zio®Patch cardiac monitoring device can efficiently characterize symptomatic patients without significant arrhythmia and has a higher diagnostic yield for arrhythmias than traditional 24-48 hour Holter monitoring. It allows for longer term monitoring up to 14 days. [West J Emerg Med. 2014;15(2:194–198.

    Rupture of posterior urethra is usually seen in major traumas with associated pelvic fractures. Clinical presentation classically associates blood at the uretral meatus and urinary retention. Urinary diversion should be achieved by suprapubic puncture and major associated traumatic injuries (abdominal, orthopaedic, and neurological lesions) must be treated prior to urological management. Retrograde uretrocystography is performed a few days later in order to localize and classify the urethral lesion. Treatment of posterior urethral ruptures has evolved over the years. Immediate open repair is no longer recommended. The supra-pubic catheter can be left in place until resorption of the pelvic hematoma. Obliteration occurs in 100% of the cases and is treated by open surgery at 3 months. More and more patients are treated by early endoscopic realignment which has diminished by half the incidence of urethral strictures. Impotence and incontinence secondary to trauma or surgery occur in 20% and 10% of the patients respectively. Long term follow-up should be achieved in every patient.

    Full Text Available Background. Due to anatomical proximity to bone, the radial nerve is the most frequently injured major nerve of the upper extremity, frequently secondary to fractures (Li et al. (2013. We describe an incidence when a branch of the radial nerve is injured as a result of a thermal injury. Observation. Radial nerve injury can occur anywhere along the anatomical course with varied etiologies, but commonly related to trauma. The most frequent site is in the proximal forearm involving the posterior interosseous branch. However, problems can occur at the junction of the middle and proximal thirds of the humerus and wrist radially. When the radial nerve is injured by a burn, a new rehabilitation dynamic arises. Not only does one agonize about the return of nerve function but also fret about the skin grafts that replaced the devitalized tissue housing that compartment. Discussion. Although posterior interosseous nerve syndrome has been described in the context of many different etiologies, it has not previously been discussed in relation to burn injuries. In this case, not only did the patient’s rehabilitation involve aggressive therapy for return of sensation and function of the arm, but also prevention of contracture normally seen in replacement of full thickness burns.

    Background The results after acetabular fracture are primarily related to the quality of the articular reduction. We evaluated the results of internal fixation of posterior wall fractures with using three-step reconstruction. Methods Thirty-three patients (mean age at the time of injury, 47.9 years; 28 males and 5 females) were followed for a minimum of 2 years after surgery. The three-step reconstruction included 1) preservation of soft tissues and reduction of the marginally impacted osteochondral (articular) fragments using screws, 2) filling the impacted cancellous void with a bone graft, and 3) reinforcement with buttress-plating. Clinical evaluation was done according to the criteria of D'aubigne and Postel, while the radiological criteria were those of Matta. The associated injuries and complications were evaluated. Results The clinical results were excellent in 15 (45.5%) patients and they were good in 5 (15.2%), (i.e., satisfactory in 60.7%), while the radiologic results were excellent in 10 (30.3%) and good in 14 (42.4%) (satisfactory in 72.7%). Heterotopic ossification was common, but this did not require excision, even without prophylactic treatment with indomethacin. Deep infection was the worst complication and this was accompanied by a poor outcome. Conclusions This study confirms that three-step reconstruction facilitates accurate and firm reduction of displaced posterior wall fractures of the acetabulum. Therefore, we anticipate less long-term arthrosis in the patients treated this way. PMID:21629471

    To explore the treatment methods and outcome of posterior wall fractures of the acetabulum. The data of 31 patients (25 males and 6 females, aged 19-59 years, mean: 40.5 years) with posterior wall fractures of the acetabulum hospitalized in our department from 2002 to 2006 were analyzed retrospectively in this study. The types of fractures, number of fragments, combined dislocations, and sciatic nerve function were documented before admission. All the fractures were treated with open reduction and internal fixation. Based on the fracture type and site, either screws alone or reconstructive plates were used. The patients were immobilized for an average of 12 weeks before partial weight bearing was permitted. After follow-up for 12-70 months (43.6 months on average), modified Merle d'Aubigne score was adopted to evaluate the outcomes of the operations. The percentages of the excellent, good, fair and poor results were 48.4%, 41.9%, 6.5%, and 3.3%, respectively, with a good to excellent rate of 90.2%. Idiopathic sciatic nerve injury occurred in only one case. The sciatic nerve should be routinely exposed and protected during the surgery. The type of fixation should be based on the fracture type and site. Prolonged immobilization may be helpful in improving the final outcomes.

    Cystic echinococcus (CE) is an endemic zoonosis secondary to infection by the larval form of the cestode Echinococcus granulosus. An intermediate host, humans enter the organism's life cycle by exposure to infected canid feces. The liver is the most common location of CE while mediastinal hydatid cysts are rarely reported. We report a case of synchronous CE of the liver and posterior mediastinum treated sequentially using chemotherapy, percutaneous aspiration with injection of a scolicidal agent and re-aspiration (PAIR) and then staged minimally-invasive surgeries. Synchronous CE involving the liver and posterior mediastinum is rare. The treatment of hydatid liver and mediastinal disease is multimodal including chemotherapy, percutaneous and laparoscopic or open surgical interventions. One option for controlled puncture of hepatic and mediastinal CE includes PAIR followed by surgery. The sequential use of chemotherapy and PAIR followed by surgery provides another treatment strategy for management of CE. We believe this strategy may be used safely in locations without endemic CE, including most regions of the United States. Published by Elsevier Ltd.

    Hemostasis is difficult in patients with bleeding emanating from the deep regions in the nasal cavity; however, there is no standard treatment method. We studied hemostasis procedures in patients who visited our outpatient department and presented with idiopathic epistaxis extending from the posterior nasal cavity to Kiesselbach's area. The subjects were patients with epistaxis who visited our hospital between June 2008 and May 2010. We asked specific questions at the time of the hospital visit and examined patients using a nasal speculum, a flexible endoscope, and a rigid endoscope (0 or 70 degree) to identify bleeding sites. Hemostasis using electrocoagulation was selected as the first-line therapy for patients in whom a bleeding point had been identified, whereas hemostasis using a gauze tampon was performed in patients in whom the bleeding point was unknown. The subjects were analyzed by multivariate logistic regression analysis. The bleeding point was unknown in most cases of recurrent posterior epistaxis. Electrocoagulation was the best hemostasis procedure. Identifying the bleeding points as much as possible and performing electrocoagulation at these sites was the preferred procedures. We propose the treatment procedure for refractory epistaxis. When it is difficult to identify a bleeding point in a patient with refractory epistaxis due to a deviated nasal septum, a bleeding point should be identified after septoplasty; for bleeding from the sphenopalatine artery region, electrocoagulation or endoscopic cauterization of the sphenopalatine artery should be performed.

    The treatment of posterior canal benign paroxysmal positional vertigo often involves repositioning maneuvers and exercises; however, these procedures may not be suitable for patients with limb disabilities or back disorders, or for elder patients. We sought to develop a simple therapeutic maneuver as an alternative procedure, suitable for patients with a wide range of physical ability. A simple therapeutic maneuver, supine to prolonged lateral position, was developed based on the mechanism of canalolithiasis. Its efficacy in treating posterior canal benign paroxysmal positional vertigo was evaluated in a prospective study consisting of 81 objective and 13 subjective posterior canal benign paroxysmal positional vertigo patients. A successful outcome was defined as a negative Dix-Hallpike test within 2 weeks followed by the continued absence of symptoms of vertigo or dizziness for the next 4 weeks. Seventy-two patients with objective posterior canal benign paroxysmal positional vertigo and all 13 patients with subjective posterior canal benign paroxysmal positional vertigo were successfully treated: resolution rates were 88.9 and 100 %, respectively. In the objective group, negative Dix-Hallpike tests were obtained at 1 and 2 weeks in 66.7 and 88.9 % of patients, respectively. In the subjective group, the percentages of patients free of side-dependent vertigo illusions at 1 and 2 weeks were 84.6 and 100 %, respectively. These results suggest that the supine to prolonged lateral position maneuver, which is easy to perform and generally well tolerated, could be recommended as an alternative treatment modality for patients with posterior canal benign paroxysmal positional vertigo.

    Magnetic resonance (MR) images from consecutive 100 patients with ossification of the posterior longitudinal ligament (OPLL) were retrospectively reviewed to determine MR manifestations of OPLL foci (ossificated foci) and the surrounding tissue. MR images from 50 patients with cervical spondylosis served as controls for comparison. Inside ossificated foci were isointense or hyperintense on T1-weighted images in 43% of the OPLL cases and on T2-weighted images in 38%. According to X-ray proven ossification form, both T1- and T2-weighted images showed isointensity or hyperintensity in approximately half of the cases of continuous and mixed types of ossificated foci. Two characteristic morphologies of cervical disc were seen more frequently in OPLL than cervical spondylosis, which has clinical implication for continuously proliferated fibrocartilage in the cervical disc. Hypertrophy of the posterior longitudinal ligament was seen in 7% of OPLL cases on MR images, reflecting the likelihood of precursor condition of ossification. (N.K.).

    To evaluate glenoid version and humeral subluxation on preoperative multiplanar imaging of patients who underwent surgery for posterior glenohumeral instability compared with a matched group of patients who had shoulder surgery for other pathology. All patients over a 2-year period who underwent surgery for posterior instability had preoperative magnetic resonance (MR) imaging or MR arthrogram reviewed. Patients undergoing shoulder surgery for reasons other than instability were identified as a control group and matched by sex, laterality, and age. Measurement of glenoid version and percentage of humeral subluxation was performed by 2 reviewers after completing a tutorial. Reviewers were blinded to diagnosis and to whether or not the patients were in the experimental or control group. There were 41 patients in each group. The average glenoid version in the control group was 5.6° of retroversion (standard deviation [SD] 3.0), and the average humeral subluxation was 54% (SD 5.1%). In the experimental group, the average glenoid version was 8.1° of retroversion (SD 5.0). The average humeral subluxation in the experimental group was 56% (SD 6.8%). Student t test revealed a statistically significant difference in glenoid version (P = .009) but not humeral subluxation (P = .25). Intra- and inter-rater reliability was measured by the intraclass correlation coefficient and found to have an excellent Fleiss rating with regard to both measurements. Glenoid retroversion is significantly increased in patients with symptomatic posterior labral tears compared with a control group. However, there was no statistically significant difference between the groups with regard to posterior humeral subluxation and, therefore, is not a reliable indicator of the presence or absence of symptomatic posterior shoulder instability.

    Sidhu, Ravindar S.; Walker, G. Ross

    Objectives To provide baseline data on resident continuity of care experience, to describe the effect of ambulatory centre surgery on continuity of care, to analyse continuity of care by level of resident training and to assess a resident-run preadmission clinic’s effect on continuity of care. Design Data were prospectively collected for 4 weeks. All patients who underwent a general surgical procedure were included if a resident was present at operation. Setting The Division of General Surgery, Queen’s University, Kingston, Ont. Outcome measures Preoperative, operative and inhospital postoperative involvement of each resident with each case was recorded. Results Residents assessed preoperatively (before entering the operating room) 52% of patients overall, 20% of patients at the ambulatory centre and 83% of patients who required emergency surgery. Of patients assessed by the chief resident, 94% were assessed preoperatively compared with 32% of patients assessed by other residents ( p 0.1). Conclusions This study serves as a reference for the continuity of care experience in Canadian surgical programs. Residents assessed only 52% of patients preoperatively, and only 40% of patients had complete continuity of care. Factors such as ambulatory surgery and junior level of training negatively affected continuity experience. Such factors must be taken into account in planning surgical education. PMID:10526519

Dexmedetomidine-loading infusion was 1 mcg/kg over 10 minutes, followed by a maintenance infusion (0.5 mcg/kg/h.Results: Nine patients were operated on under topical anesthesia: two scleral buckle, five cryopexy, one scleral laceration, and one pars plana vitrectomy with very dense laser therapy in an albinotic fundus; six patients had retinal detachment. General or local anesthesia were not possible due to medical or ocular morbidities, use of anticoagulants, or the surgery plan changed intraoperatively when new pathologies were discovered. The surgeon achieved good surgical control in eight of nine cases, with one patient having ocular and bodily movements that were disturbing. Six patients had no pain, while three patients reported mild pain. No adverse effects were noted and all patients had successful surgical outcomes. Heart rate, blood pressure, and oxygen saturation were well controlled throughout the procedures. The most frequent adverse reactions of dexmedetomidine reported in the literature in less than 5% (hypotension, bradycardia, and dry mouth were not recorded in the present study.Conclusion: When a surgeon has planned to do a pars plana vitrectomy under topical anesthesia and the surgical situation dictates the addition of cryopexy, scleral buckle, or intense laser retinopexy, then sedation with dexmedetomidine can help in the control of ocular pain in the majority of cases, with good

    Hospitalizations for ambulatory care sensitive conditions (ACSC) represent an indirect measure of access and quality of community care. This study explored hospitalization rates for 1 ACSC, uncomplicated hypertension, and the factors associated with hospitalization. A cohort of patients with incident hypertension, and their covariates, was defined using validated case definitions applied to International Classification of Disease administrative health data in 4 Canadian provinces between fiscal years 1997 and 2004. We applied the Canadian Institute for Health Information's case definition to detect all patients who had an ACSC hospitalization for uncomplicated hypertension. We employed logistic regression to assess factors associated with an ACSC hospitalization for uncomplicated hypertension. The overall rate of hospitalizations for uncomplicated hypertension in the 4 provinces was 3.7 per 1000 hypertensive patients. The risk-adjusted rate was lowest among those in an urban setting (2.6 per 1000; 95% confidence interval [CI], 2.3-2.7), the highest income quintile (3.4 per 1000; 95% CI, 2.8-4.2), and those with no comorbidities (3.6 per 1000; 95% CI, 3.2-3.9). Overall, Newfoundland had the highest adjusted rate (5.7 per 1000; 95% CI, 4.9-6.7), and British Columbia had the lowest (3.7 per 1000; 95% CI, 3.4-4.2). The adjusted rate declined from 5.9 per 1000 in 1997 to 3.7 per 1000 in 2004. We found that the rate of hospitalizations for uncomplicated hypertension has decreased over time, which might reflect improvements in community care. Geographic variations in the rate of hospitalizations indicate disparity among the provinces and those residing in rural regions. Copyright © 2013 Canadian Cardiovascular Society.

    2017-04-01

    Video ambulatory EEG (V-AEEG) is a new technique which could add increased capacity for long term EEG monitoring to overstretched inpatient video telemetry (IPVT) services. We compare V-AEEG and IPVT for diagnostic efficacy, recording quality, patient acceptability and technologist time required. Forty-one V-AEEG and 64 IPVT adult patients were included. Patients were investigated to diagnose attacks or to obtain polysomnography (PSG) prior to multiple sleep latency test (MSLT). Number of attacks recorded, whether the diagnostic question was answered, quality of video and EEG recording and patients' preference for investigation at home or in hospital were noted. For V-AEEG patients, ease of procedure and extra technologist time required were recorded. Of patients investigated for diagnosis of attacks, 74% V-AEEG patients and 62% IPVT had typical attacks during the investigation. All PSGs were useful in interpreting the MSLTs. Diagnostic questions were answered by 73% V-AEEGs and 73% IPVTs. Quality of EEG and video recording was similar using V-AEEG and IPVT. Four patients had difficulty using V-AEEG equipment but diagnostic information was lost in only one. 5% of V-AEEG patients would have preferred hospital investigation but 45% of IPVT patients would have preferred home investigation. Extra technologist time for home visits (mean 2h) was required only for the first 7 patients. Video EEG recording quality and diagnostic efficacy from V-AEEG are similar to IPVT. V-AEEG is acceptable to most patients and does not require additional technical time. Hence, V-AEEG offers a convenient, economical alternative to IPVT. Copyright © 2017 British Epilepsy Association.

    2015-01-01

    Background and purpose Instrumented 3-D gait analyses (GA) in children with cerebral palsy (CP) have shown improved gait function 1 year postoperatively. Using GA, we assessed the outcome after 5 years and evaluated parental satisfaction with the surgery and the need for additional surgery. Patients and methods 34 ambulatory children with spastic diplegia had preoperative GA. Based on this GA, the children underwent 195 orthopedic procedures on their lower limbs at a mean age of 11.6 (6–19) years. On average, 5.7 (1–11) procedures per child were performed. Outcome measures were evaluation of gait quality using the gait profile score (GPS) and selected kinematic parameters, functional level using the functional mobility scale (FMS), and the degree of parental satisfaction. Results The mean GPS improved from 20.7° (95% CI: 19–23) preoperatively to 15.4° (95% CI: 14–17) 5 years postoperatively. There was no significant change in GPS between 1 and 5 years. The individual kinematic parameters at the ankle, knee, and hip improved statistically significantly, as did gait function (FMS). The mean parental satisfaction, on a scale from 0 to 10, was 7.7 (2–10) points. There was a need for additional surgical procedures in 14 children; this was more frequent in those who had the index operation at an early age. Interpretation The main finding was that orthopedic surgery based on preoperative GA gave marked improvements in gait function and quality, which were stable over a 5-year period. Nevertheless, additional orthopedic procedures were necessary in almost half of the children and further follow-up with GA for more than 1 year postoperatively is recommended in children with risk factors for such surgery.

    In older adults, impaired control of standing balance in the lateral direction is associated with the increased risk of falling. Assessing the factors that contribute to impaired standing balance control may identify areas to address to reduce falls risk. To investigate the contributions of physiological factors to standing lateral balance control. Two hundred twenty-two participants from the Pittsburgh site of the Health, Aging and Body Composition Study had lateral balance control assessed using a clinical sensory integration balance test (standing on level and foam surface with eyes open and closed) and a lateral center of pressure tracking test using visual feedback. The center of pressure was recorded from a force platform. Multiple linear regression models examined contributors of lateral control of balance performance, including concurrently measured tests of lower extremity sensation, knee extensor strength, executive function, and clinical balance tests. Models were adjusted for age, body mass index, and sex. Larger lateral sway during the sensory integration test performed on foam was associated with longer repeated chair stands time. During the lateral center of pressure tracking task, the error in tracking increased at higher frequencies; greater error was associated with worse executive function. The relationship between sway performance and physical and cognitive function differed between women and men. Contributors to control of lateral balance were task-dependent. Lateral standing performance on an unstable surface may be more dependent upon general lower extremity strength, whereas visual tracking performance may be more dependent upon cognitive factors. Lateral balance control in ambulatory older adults is associated with deficits in strength and executive function.

    The importance of electronic medical records for the healthcare system is well documented. IT enables easy storage, communication and decision support and can provide important tools in the care of chronically ill patients in the form of a reminder system. A questionnaire was developed and send out to 1200 physicians extracted from the official data base. After four weeks the non-responders received a written reminder. Data collection started in December 2007 and was completed in February 2008. 719 questionnaires were received back, representing a response rate of 59.9%. The data revealed a significant underuse of electronic medical records (EMRs) and IT compared to other European countries. Smaller practices, older physicians and especially primary care physicians tended to use less EMR. Only 10.2% of all physicians declared an interest in considering investment in IT in the next three years, 66.9% expressly denied wishing to do so. The most important barriers were the costs, the unclear benefit and a feared worsening of the doctor-patient-communication during consultation. IT and especially EMRs are underused in daily ambulatory care in Switzerland. To increase the use of EMRs, several approaches could be helpful. First of all, the benefit of EMRs in daily routine care have to be increased as, for example, by decision support systems, tools to avoid pharmaceutical interactions and reminder systems to enable a proactive treatment of chronically ill patients. Furthermore, adequate approaches to offer appropriate reimbursement for the financial investments have to considered such as an additional payment for electronically generated, evidence based quality indicators.

    The widely used K-means clustering is a hard clustering algorithm. Here we propose a Elastic K-means clustering model (EKM) using posterior probability with soft capability where each data point can belong to multiple clusters fractionally and show the benefit of proposed Elastic K-means. Furthermore, in many applications, besides vector attributes information, pairwise relations (graph information) are also available. Thus we integrate EKM with Normalized Cut graph clustering into a single clustering formulation. Finally, we provide several useful matrix inequalities which are useful for matrix formulations of learning models. Based on these results, we prove the correctness and the convergence of EKM algorithms. Experimental results on six benchmark datasets demonstrate the effectiveness of proposed EKM and its integrated model.

    Twenty-eight cases of posterior choroidal melanoma were treated with iodine-125 in gold eye plaques. Eleven cases were located within 3.0 mm of the optic nerve (group A), nine were within 3.0 mm of the fovea (group B), and eight were within 3.0 mm of the optic nerve and fovea (group C). The mean follow-up of group A was 46.3 months; group B, 25.5 months; and group C, 42.7 months. Complications included macular edema, cataract and tumor growth. Visual acuity remained within two lines of that tested preoperatively for 4 of 11 patients in group A, 4 of 9 in group B, and 5 of 8 in group C. These results with iodine-125 suggest it as an appropriate treatment for patients with choroidal melanoma located near optic nerve and/or macula

    Disorders of the posterior pelvic floor are relatively common. The role of imaging in this field is increasing, especially in constipation, prolapse and anal incontinence, and currently imaging is an integral part of the investigation of these pelvic floor disorders. Evacuation proctography provides both structural and functional information for rectal voiding and prolapse. Dynamic MRI may be a valuable alternative as the pelvic floor muscles are visualised, and it is currently under evaluation. Endoluminal imaging is important in the management of anal incontinence. Both endosonography and endoanal MRI can be used for detection of anal sphincter defects. Endoanal MRI has the advantage of simultaneously evaluating external sphincter atrophy, which is an important predictive factor for the outcome of sphincter repair. Many aspects of constipation and prolapse remain incompletely understood and treatment is partly empirical; however, imaging has a central role in management to place patients into treatment-defined groups.

    Posterior cruciate ligament (PCL) injuries are less frequent than anterior cruciate ligament (ACL) injuries, but are presumably more common than once thought. Thirty-nine patients with PCL injuries identified on MR images were studied. The criteria for PCL injury were complete tear, partial tear, and avulsion fracture. The approximate site of a partial tear was categorized as proximal, midsubstance, distal, or combination. Fourteen patients (35.9%) had complete tears of the PCL, 21 patients (53.8%) had partial tears, and four patients (10.3%) had avulsion fractures. A total of 12 patients (30.7%) had isolated PCL injuries, while the remaining 27 patients demonstrated evidence of other coexistent knee injuries, such as meniscal tears and ligamentous injuries. Of coexistent knee injuries, meniscal tears (18 patients, 46.2%) were most often seen. (author)

    Full Text Available Urethral diverticulum is a localized saccular or fusiform out-pouching of the urethra. It may occur at any point along the urethra in both male and females. Male urethral diverticulum is rare, and could be either congenital or acquired, anterior or posterior. The mainstay treatment of posterior urethral diverticulum (PUD is the open surgical approach. Here we discuss our minimally invasive surgical approach (MIS in managing posterior urethral diverticulum.

Significant differences in 25-OH D levels were noted between PSC subjects taking/not taking calcium supplements, systemic steroids, osteoporosis medications, etc. Alone, smoking status and calcium channel blockers and/or topical steroids use made no significant difference in PSC subjects 25-OH D levels, but two or more of these factors were associated with lowered levels of 25-OH D (P<0.001. Low vitamin D was correlated with female sex, autoimmune disease, and non-skin cancer diagnosis, but not with age, or other comorbidities or medication use. In five early-stage PSC patients taking 5,000 IU of 25-OH D daily for vitamin D deficiency, there was resolution of their cataracts during the 2-year follow-up period.Conclusion: Vitamin D levels for most PSC patients fell below the 30 ng/mL calcium homeostasis threshold. Some comorbidities and non-ophthalmic interventions are associated with the development of PSC at less depressed levels of 25-OH D. In this series, vitamin D deficiency was associated with PSC cataract, suggesting that raising the level of vitamin D intake may reduce PSC incidence.Keywords: posterior subcapsular, cataracts, vitamin D deficiency, risk factors, hypocalcemia, case report

    Many patients are hypertensive at the medical settings but show normal blood pressure out of the doctor's office, and are classified as white-coat hypertensives. On the other hand, many patients with controlled hypertension at the clinic show ambulatory blood pressure levels above the thresholds considered for an adequate blood pressure control, known as having masked hypertension. Using data from the Spanish Ambulatory Blood Pressure Monitoring Registry (Spanish ABPM Registry), a national program developed to promote the use of the ambulatory technique for hypertension management in daily practice, we have reviewed the main strengths of this approach, that is the ability to detect discrepancies of blood pressure status with respect to office blood pressure measurement, and to better assess accurate rates of hypertension control. White-coat hypertension within patients with elevated office blood pressure, and masked hypertension within office-controlled patients affected one of three patients in each office status. On the other hand, rates of ambulatory blood pressure control (50%) doubled those of office blood pressure control (25%), still remaining half the patients uncontrolled. We think that a systematic use of ambulatory blood pressure monitoring, and strategies to improve blood pressure control constitute key priorities in hypertension management. © 2015 Stichting European Society for Clinical Investigation Journal Foundation.

  16. Perspectives on ambulatory anesthesia: the patient’s point of view

    Full Text Available Herman Sehmbi, Jean Wong, David T WongDepartment of Anesthesia, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, CanadaAbstract: Recent advances in anesthetic and surgical techniques have led to tremendous growth of ambulatory surgery. With patients with many co-morbid conditions undergoing complex procedures in an ambulatory setting, the challenges in providing ambulatory surgery and anesthesia are immense. In recent years, the paradigm has shifted from a health-care provider focus involving process compliance and clinical outcomes, to a patient-centered strategy that includes patients’ perspectives of desired outcomes. Improving preoperative patient education while reducing unnecessary testing, improving postoperative pain management, and reducing postoperative nausea and vomiting may help enhance patient satisfaction. The functional status of most patients is reduced postoperatively, and thus the pattern of recovery is an area of ongoing research. Standardized and validated psychometric questionnaires such as Quality of Recovery-40 and Postoperative Quality of Recovery Scale are potential tools to assess this. Patient satisfaction has been identified as an important outcome measure and dedicated tools to assess this in various clinical settings are needed. Identification of key aspects of ambulatory surgery deemed important from patients’ perspectives, and implementation of validated outcome questionnaires, are important in improving patient centered care and patient satisfaction.Keywords: ambulatory, patient, satisfaction, anesthesia, outcomes, questionnaire, perspectives

  17. Sustainable business models: systematic approach toward successful ambulatory care pharmacy practice.

    This article discusses considerations for making ambulatory care pharmacist services at least cost neutral and, ideally, generate a margin that allows for service expansion. The four pillars of business sustainability are leadership, staffing, information technology, and compensation. A key facet of leadership in ambulatory care pharmacy practice is creating and expressing a clear vision for pharmacists' services. Staffing considerations include establishing training needs, maximizing efficiencies, and minimizing costs. Information technology is essential for efficiency in patient care delivery and outcomes assessment. The three domains of compensation are cost savings, pay for performance, and revenue generation. The following eight steps for designing and implementing an ambulatory care pharmacist service are discussed: (1) prepare a needs assessment, (2) analyze existing strengths, weaknesses, opportunities, and threats, (3) analyze service gaps and feasibility, (4) consider financial opportunities, (5) consider stakeholders' interests, (6) develop a business plan, (7) implement the service, and (8) measure outcomes. Potential future changes in national healthcare policy (such as pharmacist provider status and expanded pay for performance) could enhance the opportunities for sustainable ambulatory care pharmacy practice. The key challenges facing ambulatory care pharmacists are developing sustainable business models, determining which services yield a positive return on investment, and demanding payment for value-added services.

    Falls and fear of falling (FOF) are common in persons with late effects of polio, but there is limited knowledge of associated factors. To determine how knee muscle strength, dynamic balance, and gait performance (adjusted for gender, age, and body mass index) are associated with falls and FOF in persons with late effects of polio. A cross-sectional study. A university hospital outpatient clinic. Eighty-one ambulatory persons with verified late effects of polio (43 men; mean age 67 years). Number of falls the past year, Falls Efficacy Scale-International to assess FOF, a Biodex dynamometer to measure knee muscle strength, the Timed Up & Go test to assess dynamic balance, and the 6-Minute Walk test to assess gait performance. Univariate and multivariate logistic regression analyses were used for falls (categorical data) and linear regression analyses for FOF (continuous data) as dependent variables. Fifty-nine percent reported at least 1 fall during the past year, and 79% experienced FOF. Reduced knee muscle strength in the more affected limb and gait performance were determinants of falls. An increase of 10 Nm in knee flexor and knee extensor strength reduced the odds ratio between 0.70 and 0.83 (P = .01), and an increase of 100 m in 6-Minute Walk test reduced the odds ratio to 0.41 (P = .001). All factors were determinants of FOF; reduced knee muscle strength in the more and less affected limbs explained 17%-25% of the variance in FOF, dynamic balance 30%, and gait performance 41%. Gender, age, and body mass index only marginally influenced the results. Reduced gait performance, knee muscle strength, and dynamic balance are to a varying degree determinants of falls and FOF in ambulatory persons with late effects of polio. Future studies need to evaluate whether rehabilitation programs targeting these factors can reduce falls and FOF in this population. IV.

    Deltoid paralysis after axillary nerve injury results in limitations in shoulder function and stability. In the setting of an isolated axillary nerve injury with no clinical or electromyographic evidence of recovery that is within 6 to 9 months postinjury, the authors' preferred technique to reinnervate the deltoid is to reconstruct the axillary nerve with sural nerve grafting. Intraoperative neuromuscular electrophysiology is critical to determine the continuity of the axillary nerve before proceeding with reconstruction. The majority of the time, both an anterior and posterior incision and dissection of the axillary nerve is required to adequately delineate the zone of injury. This also ensures that both proximally and distally, uninjured axillary nerve is present before graft inset and also facilitates the ability to perform a meticulous microsurgical inset of the nerve graft posteriorly. The nerve graft must be pulled through from posterior to anterior to span the zone of injury and reconstruct the axillary nerve. Careful infraclavicular brachial plexus dissection is necessary to prevent further injury to components of the brachial plexus in the setting of a scarred bed. Patients will require postoperative therapy to prevent limitations in shoulder range of motion secondary to postoperative stiffness. This paper presents a detailed surgical technique for axillary nerve reconstruction by an anterior-posterior approach with a pull-through technique of a sural nerve cable graft.

    It is generally accepted that cervical spine bilateral facet dislocation results in complete disruption of the posterior longitudinal ligament. The goal of this study was to evaluate the integrity of numerous spine-stabilizing structures by MRI, and to determine if any associations between injury patterns exist with respect to the posterior longitudinal ligament status. Retrospective case series. A retrospective review was performed of 30 cervical spine injury subjects with bilateral facet dislocation. Assessment of 1.5T MRI images was carried out for: intervertebral disc disruption, facet fracture, and ligamentous disruption. Statistical analyses were performed to evaluate for associations between various injury patterns and posterior longitudinal ligament status. The frequency of MRI abnormalities was: anterior longitudinal ligament disruption (26.7%), disc herniation or disruption (90%), posterior longitudinal ligament disruption (40%), facet fracture (63.3%) and disruption of the posterior column ligament complex (97%). There were no significant associations between injury to the posterior longitudinal ligament and other structures. Compared to surgical reports, MRI was accurate for determining the status for 24 of 26 ligaments (three of three anterior longitudinal ligament, seven of nine posterior longitudinal ligament, and 14 of 14 posterior column ligament complex) but generated false negatives in two instances (in both MRI showed an intact posterior longitudinal ligament that was torn at surgery).
