Identifying trajectories of change in sleep disturbance during psychological treatment for depression.

BACKGROUND: Sleep disturbance may impact response to psychological treatment for depression. Understanding how sleep disturbance changes during the course of psychological treatment, and identifying the risk factors for sleep disturbance response may inform clinical decision-making. METHOD: This analysis included 18,915 patients receiving high-intensity psychological therapy for depression from one of eight London-based Improving Access to Psychological Therapies (IAPT) services between 2011 and 2020. Distinct trajectories of change in sleep disturbance were identified using growth mixture modelling. The study also investigated associations between identified trajectory classes, pre-treatment patient characteristics, and eventual treatment outcomes from combined PHQ-9 and GAD-7 metrics used by the services. RESULTS: Six distinct trajectories of sleep disturbance were identified: two demonstrated improvement, while one showed initial deterioration and the other three groups displayed only limited change in sleep disturbance, each with varying baseline sleep disturbance. Associations with trajectory class membership were found based on: gender, ethnicity, unemployment status, antidepressant medication use, long-term health condition status, severity of depressive symptom, and functional impairment. Groups that showed improvement in sleep had the best eventual outcomes from depression treatment, followed by groups that consistently slept well. LIMITATION: Single item on sleep disturbance used, no data on treatment adherence. CONCLUSIONS: These findings reveal heterogeneity in the course of sleep disturbance during psychological treatment for depression. Closer monitoring of changes in sleep disturbance during treatment might inform treatment planning. This includes decisions about when to incorporate sleep management interventions, and whether to change or augment therapy with interventions to reduce sleep disturbance.

Predicting post-treatment symptom severity for adults receiving psychological therapy in routine care for generalised anxiety disorder: a machine learning approach.

Approximately half of generalised anxiety disorder (GAD) patients do not recover from first-line treatments, and no validated prediction models exist to inform individuals or clinicians of potential treatment benefits. This study aimed to develop and validate an accurate and explainable prediction model of post-treatment GAD symptom severity. Data from adults receiving treatment for GAD in eight Improving Access to Psychological Therapies (IAPT) services (n=15,859) were separated into training, validation and holdout datasets. Thirteen machine learning algorithms were compared using 10-fold cross-validation, against two simple clinically relevant comparison models. The best-performing model was tested on the holdout dataset and model-specific explainability measures identified the most important predictors. A Bayesian Additive Regression Trees model out-performed all comparison models (MSE=16.54 [95 % CI=15.58; 17.51]; MAE=3.19; R²=0.33, including a single predictor linear regression model: MSE=20.70 [95 % CI=19.58; 21.82]; MAE=3.94; R²=0.14). The five most important predictors were: PHQ-9 anhedonia, GAD-7 annoyance/irritability, restlessness and fear items, then the referral-assessment waiting time. The best-performing model accurately predicted post-treatment GAD symptom severity using only pre-treatment data, outperforming comparison models that approximated clinical judgement and remaining within the GAD-7 error of measurement and minimal clinically important differences. This model could inform treatment decision-making and provide desired information to clinicians and patients receiving treatment for GAD.

Examining bi-directional change in sleep and depression symptoms in individuals receiving routine psychological treatment.

BACKGROUND: Sleep disturbance is a common symptom of depression. There is conflicting evidence whether improvements in sleep might impact depressive symptoms, or whether treating the core depressive symptoms might improve sleep disturbance. This study explored the bi-directional impact of sleep and depressive symptom change among individuals receiving psychological treatment. METHODS: Session-by-session change in sleep disturbance and depressive symptom severity scores were explored in patients receiving psychological therapy for depression from Improving Access to Psychological Therapies services in England. Bi-directional change in sleep disturbance and depressive symptoms was modelled using random-intercept cross-lagged panel models with items from the PHQ-9. RESULTS: The sample included 17,732 adults that had received three or more treatment sessions. Both depressive symptoms and sleep disturbance scores decreased. Between initial timepoints, higher sleep disturbance was associated with lower depression scores, but after this point positive cross-lagged effects were observed for both the impact of sleep disturbance on later depressive symptoms, and depressive symptoms on later sleep disturbance scores. The magnitude of effects suggested depressive symptoms may have more impact on sleep than the reverse, and this effect was larger in sensitivity analyses. CONCLUSIONS: Findings provide evidence that psychological therapy for depression results in improvements in core depressive symptoms and sleep disturbance. There was some evidence that depressive symptoms may have more impact on sleep disturbance scores at the next therapy session, than sleep disturbance does on later depressive symptoms. Targeting the core symptoms of depression initially may optimise outcomes, but further research is needed to elucidate these relationships.

The level and distribution of selected organochlorine pesticides in water of River Satluj Pakistan.

The study was aimed to identify different environmental factors (selected organochlorine pesticides) affecting the river water of Satluj. River Sutlej is about 1400 kilometers long and its water is extensively used for irrigation in Punjab, located both in India and Pakistan, which was also a reason of dispute between both countries for its water share. The study area was divided into four zones, Sulemanki Zone, Islam Zone, Mailsi Syphone Zone and Panjnad Zone. Liquid Liquid Extraction (LLE) technique was used for the collected water samples followed by high performance liquid chromatography (HPLC) UV-Visible detector The current finding revealed that aldrin was not detected during summer period in water samples of SZ-1 (Sulemanki Barrage), SZ-2 and SZ-3 (Maisli Siphon) of the study area. Lindane and DDE were found more in the samples of sediments from the study area at SZ-4 ranging from 2.238-8.226 ppb and 4.234-6.876 ppb, respectively. Heaptachlor (in sediments) was found to be0.032-234 ppb only at SZ-4.Endosulfan concentrations in water (winter) at SZ-3 was 0.06 ppb and at SZ-4,it was 0.05 ppb; dieldrin in water (winter) at SZ-4 was 0.0314 ppb and heptachlor was detected at SZ-1 (0.0315 ppb) and SZ-2 (0.0310 ppb) in water during winter season, were reaching to the Maximum Concentrations Limits (MCL), while all other residues investigated were found below the MCLin all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious. Present findings revealed that although the organochlorine pesticides are banned for agricultural use in many countries, including Pakistan, their presence in various samples might be due to illegal use of these pesticides in the study area and its neighboring regions. The overall study area comprises of mainly urban, suburban and agricultural land being the largest cotton growing area of the country. There is a need to take serious steps to minimize water pollution caused by pesticides to achieve a healthy lifestyle.

Presence of selected organochlorine pesticides (OCPs) in sediments and biota of River Satluj, Pakistan: first report.

In the developed countries, the use of OCPs (organochlorine pesticides) has been banned. However, in South Asia several of them are still in use. In Pakistan and India a constant addition of OCPs into the atmosphere has been indicated by various researchers. In this study levels of selected organochlorine pesticide residues were assessed in sediment and biota collected from four (4) water reservoirs (3 Barrages & 1 Siphon) on the River Satluj Pakistan, along 231 miles (372 km) of River stretch which was further divided into 12 sampling sites. It was aimed to find out the levels of organochlorine pesticide (OCPs) residues in sediments and from selected fish species (Labeo rohita, Wallagu attu, Cyprinus carpio) of the River Satluj Pakistan. The Organochlorine residues (seven pesticides) present in samples of sediments and biota were investigated through multi residue method, using Gas Chromatograph (GC-ECD).In the current study, the concentration of DDT, was investigated in Wallago attu (0.786-3.987 ppb), Labeo rohita (0.779-4.355 ppb) and Cyprinus carpio (1.234-5.654 ppb). DDE was also found in Cyprinus carpio (1.244-6.322 ppb), Wallag attu (0.877-4.221 ppb) and Labeo rohita (2.112-5.897 ppb). Aldrin was not observed in Labeo rohita and Wallago attu. Currently, lindane and DDE was found predominately high in the sediments of study area at SZ-4 (Panjnad Barrage) ranging (2.238-8.226 ppb) and (4.234-6.876 ppb), respectively. Heaptachlor was found only at SZ-4 (Panjnad Barrage) from the sediments with concentration ranging (0.032-234 ppb). In short all other residues investigated were found below the MCL (maximum concentration level) in all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious.

Transdiagnostic symptom dynamics during psychotherapy.

Psychotherapy is an effective treatment for many common mental health problems, but the mechanisms of action and processes of change are unclear, perhaps driven by the focus on a single diagnosis which does not reflect the heterogeneous symptom experiences of many patients. The objective of this study was to better understand therapeutic change, by illustrating how symptoms evolve and interact during psychotherapy. Data from 113,608 patients from psychological therapy services who completed depression and anxiety symptom measures across three to six therapy sessions were analysed. A panel graphical vector-autoregression model was estimated in a model development sample (N = 68,165) and generalizability was tested in a confirmatory model, fitted to a separate (hold-out) sample of patients (N = 45,443). The model displayed an excellent fit and replicated in the confirmatory holdout sample. First, we found that nearly all symptoms were statistically related to each other (i.e. dense connectivity), indicating that no one symptom or association drives change. Second, the structure of symptom interrelations which emerged did not change across sessions. These findings provide a dynamic view of the process of symptom change during psychotherapy and give rise to several causal hypotheses relating to structure, mechanism, and process.

Paediatric urolithiasis in emerging economies.

BACKGROUND: Paediatric urolithiasis remains endemic in low resource countries. This review highlights the epidemiology, causation and management of urolithiasis in an Asian country in the context of emerging economies. METHODS: A literature review of recent articles with key words paediatric urolithiasis, developing countries, endemic stone disease, stone composition, metabolic risk factors, management of paediatric urolithiasis was undertaken and 51 relevant articles were selected with the main focus on experience of this center in managing stone disease in the last two decades. RESULTS: Prevalence of paediatric urolithiasis is high upto 15% affecting children under 15 years with male predominance. Bladder stones still constitutes 10-70% of the burden. Etiology remains unknown where 55% are considered idiopathic, 25% metabolic, 7% infection and 12% due to anatomical abnormalities. Hot climate, poor nutrition, diarrheal diseases are the major causative factors. Chemical composition of stones showed CaOX in 30-63%, AAU in 17-55%, struvite in 8-9%, uric acid in 3-6% and cystine in 1%. Important metabolic risk factors are hypocitraturia in 63-87%, hyperoxaluria in 40-43%, hypocalciuria in 20%, hyperuricosuria in 27%, hyperammonuria in 11-51% and hypovolemia in 31%. Minimally invasive surgery is the mainstay of surgical management. ESWL provides excellent free rates of 84% for smaller stones. PCNL is the option for majority of renal stones with success rates of 89% for simple and 71.5% for complex stones. For bladder stones PUCL and PCCL success rates were 100%. URS for ureteric stones showed clearance rate of 90%. Open surgery is required in 12% of patients with large stone burden. CONCLUSION: Paediatric urolithiasis remains a devastating health problem in low resource settings. MIS offers relief to majority of patients with excellent stone free rates and short hospital stay. Preventable strategies have to be put in place by improving nutrition and eliminating risk factors by diet and medical intervention.

Effect of angiotensin converting enzyme inhibitor on glomerular hyperfiltration in patients with type 1 diabetes.

OBJECTIVE: To assess the effect of angiotensin converting enzyme inhibition on glomerular filtration rate (GFR) in normotensive patient with type 1 diabetes. METHODS: A two year non-placebo control prospective study was conducted after ethical approval at Diabetes Centre of Diabetic Association of Pakistan, a WHO collaborating centre in Karachi, Pakistan. All patients with type 1 diabetes visited the out-patients department from August 2009 till July 2011 and those who fulfilled the inclusion criteria were invited to participate. A total of 121 people aged ≥18 years and ≥ 5 years of diabetes were included. Pregnant and lactating woman and those aged <18 years were excluded. GFR was calculated by using CKD-EPI formula (eGFR) at baseline and after two year. On the basis of estimated GFR, patients at baseline were divided according to KDIGO classification of chronic kidney diseases into, hyperfiltration (eGFR ≥ 100 ml/min) and normal filtration group (eGFR < 100 ml/min). All subjects in hyperfiltration group received ACE inhibitor (treatment group) while patients with normal filtration did not receive ACE inhibitor (control group). RESULTS: Fifty two patients (43%) were in the treatment and sixty nine (57%) were in the control group. At baseline eGFR, systolic and diastolic blood pressures between groups were non-significantly different. After two years, compared to baseline, eGFR of the treatment group declined and the control group increased significantly. No significant difference in systolic while diastolic blood pressure of the treatment group increased significantly after two years compared to baseline. In contrast both systolic and diastolic blood pressure of control group increased significantly after two years compared to their baseline values. CONCLUSION: Present study demonstrated that initiation of ACEI in hyperfiltration stage declined GFR and keep blood pressure within normal range.

Long-term Safety of Living Kidney Donation in an Emerging Economy.

BACKGROUND: Long-term follow-up and management of donors was undertaken in a specialist kidney transplant unit in Pakistan to identify risk and prevent adverse outcomes in living related kidney donors. METHODS: In an observation cohort study between 1985 and 2012, 3748 donors were offered free medical follow-up and treatment 6 to 12 months after donation and annually thereafter. Each visit included history, physical examination, blood tests for renal, lipid, glucose profiles, and 24-hour urine for proteinuria and creatinine clearance. Preventive intervention was undertaken for new onset clinical conditions. Donor outcomes were compared with 90 nondonor healthy siblings matched for age, sex, and body mass index. RESULTS: Of the 3748 donors, 2696 (72%) were in regular yearly follow-up for up to 27 years (median, 5.6; interquartile range, 7.9). Eleven (0.4%) died 4 to 22 years after donation with all-cause mortality of 4.0/10 000 person years. Six (0.2%) developed end-stage renal disease 5 to 17 years after donation, (2.7/10 000 person years). Proteinuria greater than 1000 mg/24 hours developed in 28 patients (1%), hypertension in 371 patients (13.7%), and diabetes in 95 patients (3.6%). Therapeutic intervention-controlled protein was less than 1000 mg/24 hours, blood pressure was below 140/90 mm Hg, and glycemic control in 85% up to 15 years after onset. Creatinine clearance fell from 109.8 ± 22.3 mL/min per 1.73 m predonation to 78 ± 17 at 1 year, 84 ± 19 at 5 years, and 70 ± 20 at 25 years. Comparison of 90 nondonor sibling and donor pairs showed significantly higher fasting glucose and hypertension in nondonors. CONCLUSIONS: Long-term follow-up of donors has demonstrated end-stage renal disease in 0.6% at 25 years. Regular follow-up identified new onset of disease and allowed interventions that may have prevented adverse outcomes.

Chronic kidney disease hotspots in developing countries in South Asia.

In many developing countries in the South Asian region, screening for chronic diseases in the community has shown a widely varying prevalence. However, certain geographical regions have shown a high prevalence of chronic kidney disease (CKD) of unknown etiology. This predominantly affects the young and middle-aged population with a lower socioeconomic status. Here, we describe the hotspots of CKD of undiagnosed etiology in South Asian countries including the North, Central and Eastern provinces of Sri Lanka and the coastal region of the state of Andhra Pradesh in India. Screening of these populations has revealed cases of CKD in various stages. Race has also been shown to be a factor, with a much lower prevalence of CKD in whites compared to Asians, which could be related to the known influence of ethnicity on CKD development as well as environmental factors. The difference between developed and developing nations is most stark in the realm of healthcare, which translates into CKD hotspots in many regions of South Asian countries. Additionally, the burden of CKD stage G5 remains unknown due to the lack of registry reports, poor access to healthcare and lack of an organized chronic disease management program. The population receiving various forms of renal replacement therapy has dramatically increased in the last decade due to better access to point of care, despite the disproportionate increase in nephrology manpower. In this article we will discuss the nephrology care provided in various countries in South Asia, including India, Bangladesh, Pakistan, Nepal, Bhutan, Sri Lanka and Afghanistan.

Pediatric kidney transplantation in the developing world: challenges and solutions.

The prevalence of pediatric RRT and transplantation are low in developing countries, 6-12 and <1 to 5 per million child population (pmcp), respectively. This is due to low GDP/capita of <$10 000, government expenditure on health of <2.6-9% of GDP and paucity of facilities. The reported incidence of pediatric CKD and ESRD is <1.0-8 and 3.4-35 pmcp, respectively. RRT and transplantation are offered mostly in private centers in cities where HD costs $20-100/session and transplants $10 000-20 000. High costs and long distance to centers results in treatment refusal in up to 35% of the cases. In this backdrop 75-85% of children with ESRD are disfranchised from RRT and transplantation. Our center initiated an integrated dialysis-transplant program funded by a community-government partnership where RRT and transplantation was provided "free of cost" with life long follow-up and medication. Access to free RRT at doorsteps and transplantation lead to societal acceptance of transplantation as the therapy of choice for ESRD. This enabled us to perform 475 pediatric transplants in 25 years with 1- and 5-year graft survival of 96% and 81%, respectively. Our model shows that pediatric transplantation is possible in developing countries when freely available and accessible to all who need it in the public sector.

Implementing a public-private mix model for tuberculosis treatment in urban Pakistan: lessons and experiences.

SETTING: Six towns of Karachi, Pakistan. OBJECTIVES: 1) To strengthen the capacity of general practitioners (GPs) in providing tuberculosis (TB) treatment through DOTS; and 2) to enhance collaboration between the public and private sectors in TB management and case reporting. DESIGN: A quasi-experimental study design was adopted to ensure enrolment of TB patients through trained GPs with the support of laboratory networks and to improve the case detection rate. RESULTS: The following challenges were faced during implementation of the model in urban settings: no systematic list of GPs was available; the majority of the GPs were untrained health practitioners working in squatter settlements, where formally trained GPs are most needed; the motivation of GPs with high patient loads is very low; and access to a laboratory is difficult. Of 35 patients enrolled in the first quarter (third quarter 2009), 87% completed their treatment successfully. CONCLUSION: Public-private mix (PPM) DOTS is feasible in the cities of Pakistan. However, the cost, time and effort required to establish the programme is higher than in many other developing countries.

Experience of fibrosing cholestatic hepatitis with hepatitis C virus in kidney transplant recipients.

BACKGROUND: Fibrosing cholestatic hepatitis C (FCH-C) is a rare entity that occurs among immune-compromised patients resulting from the direct hepatotoxicity of a high intracellular viral load along with an ineffective immune system ultimately leading to a fatal outcome. We have describes herein 4 renal transplant recipients who were diagnosed with FCH-C at our institution in the last 8 months. METHODS: Four renal transplant recipients presented with jaundice and deteriorating liver function tests. They were diagnosed to display FCH-C based on the presence of hepatitis C virus (HCV) RNA and characteristic liver biopsy findings; there was no evidence of any other cause of cholestasis or biliary obstruction. RESULTS: The patients were men of ages 40, 25, 20, and 27 years. The durations after transplantation were 1.5, 10, 1.5 and 2.0 years, respectively. In all cases pretransplantation screening was negative for HCV antibody, HCV RNA, and hepatitis B surface antigen (HBsAg). All 4 patients were infected with genotype 1, whereas case 2 had coinfection with type 3. Cases 1 and 2 who were treated with interferon and ribavirin, showed improvement in cholestasis but did not achieve a rapid virological response. Case 1 developed graft dysfunction secondary to acute cellular rejection at 4 months after initiation of interferon treatment, which was treated with pulse steroids. Interferon-based therapy was stopped prematurely in both cases due to pancytopenia. Case 3 developed florid pyelonephritis and died without receiving therapy for hepatitis C. Case 4 was managed conservatively by decreasing the immunosuppression with regular monitoring. CONCLUSION: FCH-C is difficult to treat and shows high morbidity and mortality rates. Treatment is associated with a risk of graft rejection.

Induction of ROS, mitochondrial damage and autophagy in lung epithelial cancer cells by iron oxide nanoparticles.

Autophagy has attracted a great deal of research interest in tumor therapy in recent years. An attempt was made in this direction and now we report that iron oxide NPs synthesized by us selectively induce autophagy in cancer cells (A549) and not in normal cells (IMR-90). It was also noteworthy that autophagy correlated with ROS production as well as mitochondrial damage. Protection of NAC against ROS clearly suggested the implication of ROS in hyper-activation of autophagy and cell death. Pre-treatment of cancer cells with 3-MA also exhibited protection against autophagy and promote cellular viability. Results also showed involvement of classical mTOR pathway in autophagy induction by iron oxide NPs in A549 cells. Our results had shown that bare iron oxide NPs are significantly cytotoxic to human cancer cells (A549) but not to the normal human lung fibroblast cells (IMR-90).In other words our nanoparticles selectively kill cancerous cells. It is encouraging to conclude that iron oxide NPs bear the potential of its applications in biomedicine, such as tumor therapy specifically by inducing autophagy mediated cell death of cancer cells.

A renal transplantation model for developing countries.

The estimated incidence of end-stage renal disease (ESRD) in Pakistan is 100 per million population. Paucity and high costs of renal replacement therapy allows only 10% to get dialysis and 4-5% transplants. Our center, a government organization, started a dialysis and transplant program in 1980s where all services were provided free of charge to all patients. It was based on the concept of community government partnership funded by both partners. The guiding principles were equity, transparency, accountability and development of all facilities under one roof. This partnership has sustained itself for 30 years with an annual budget of $25 million in 2009. Daily 600 patients are dialyzed and weekly 10-12 receive transplants. One- and 5-year graft survival of 3000 transplants is 92% and 85%, respectively. The institute became a focus of transplantation in Pakistan and played a vital role in the campaign against transplant tourism and in promulgation of transplant law of 2007, and also helped to increase altruistic transplants in the country. This model emphasizes that in developing countries specialized centers in government sector are necessary for transplantation to progress and community support can make it available to the common man.

Living related renal transplants with lifelong follow-up. A model for the developing world.

AIMS: To describe the dynamic of a model of public government partnership for dialysis and transplantation in developing countries. MATERIALS: A model was established on the philosophy of public-government partnership to provide an integrated dialysis and transplant service "Free with dignity" with lifelong follow-up care and medications. The government provided 50% of funds and the public was motivated to donate the rest. This included affluent individuals, corporations, business houses and the general public. RESULTS: This model has been sustained for the last two decades. In 2008, 655,000 patients were treated at SIUT. Over 600 patients are dialyzed each day with a total of 165,411 dialysis sessions/year. Thus far 2,249 transplants have been performed, 431 in 2008. One- and 5-year graft survival rates were 92% and 85%, respectively. The laboratory performed 4.1 million tests and radiological investigations numbered 164,217. Over $ 6 million were spent on medications. Free services offered by the model have motivated the government to increase its funding from $ 2.1 million in 1998 to $ 10 million in 2008 and the public has matched these figures with total donations exceeding $ 20 million. CONCLUSIONS: For transplantation to be successful in developing countries, it has to be made available to the common people who constitute 90% of the population. Our model of public-government partnership has made dialysis and transplantation available to the disenfranchised with lifelong follow-up and medications. Transplantation has become relevant to them, resulting in societal acceptance of transplantation as a preferred mode of therapy. This has motivated society to support both living related and deceased donor programs.

Human organ and tissue transplantation in Pakistan: when a regulation makes a difference.

Organ transplantation must be viewed in relation to the prevailing cultural, religious and economic conditions of a nation. Over the past two decades, Pakistan has emerged as one of the largest centres for commercial renal transplantation. Government efforts, supported by professional associations, civil society organizations and the media, along with World Health Organization technical assistance, have led to the development of legislation regulating this practice and curbing organ trade in conformity with international guidelines. Although only two years have passed since the enactment of the law, there is evidence that conditions have significantly improved, raising hopes for ethical and safe organ transplantation in Pakistan. This study reviews the salient features of the legislation and lists the foreseeable evolving challenges and opportunities.

Clean intermittent catheterization in children through a continent catheterizable channel: a developing country experience.

PURPOSE: We evaluated the role of clean intermittent self-catheterization through a continent catheterizable Mitrofanoff channel in an augmented bladder in children with bladder dysfunction and outlet obstruction. MATERIALS AND METHODS: We retrospectively analyzed the records of 82 patients treated at a public sector hospital with pediatric urology services in a developing country. Patients came from all provinces of the country with diverse ethnic, cultural, linguistic, socioeconomic and educational backgrounds. RESULTS: Mean +/- SD patient age was 9.07 +/- 3.38 years (range 2.5 to 15) with a male-to-female ratio 2.5:1.0. The main congenital and acquired abnormalities were posterior urethral valves in 29% of patients, neuropathic bladder in 22%, nonneurogenic neurogenic bladder in 17%, exstrophy plus epispadias in 10% and urethral stricture in 7%. Augmentation cystoplasty was performed using various bowel segments. The Mitrofanoff channel was made using appendix in 70 cases and by the spiral Monti method in 12. A stoma was created in the right iliac fossa using VQZ plasty in 72 patients and an umbilical stoma was created in 10. Complications included bladder calculus in 3 patients, stomal stenosis in 2, subacute intestinal obstruction in 4 and acute intestinal obstruction in 1. Compliance was observed in greater than 90% of the patients at a mean followup of 860 days. CONCLUSIONS: In a developing country setting with a low socioeconomic and educational level it is possible to successfully perform augmentation cystoplasty with clean intermittent self-catheterization through a continent catheterizable channel in children with bladder dysfunction and outlet obstruction. The active role of pediatric urologists in the care, teaching and counseling together with free care to all are the reasons for acceptance and compliance.
