Item Myths and misconceptions about childhood constipation(Springer-Verlag., 2023) Rajindrajith, S.; Devanarayana, N.M.; Thapar, N.; Benninga, M.A.Many widely held beliefs and assumptions concerning childhood constipation continue to interfere with rational management of childhood constipation. Although many still believe that constipation is not a common disease, about 9.5% of the world's children suffer from chronic constipation. Most of these children live in non-Western countries. There are major misconceptions about the etiology of constipation as a significant proportion of clinicians still believe that constipation is caused by some form an organic pathology, whereas in reality, the majority have functional constipation. Contrary to a commonly held belief that children outgrow constipation without long-term problems, there is evidence that constipation leads to significant bowel and psychological consequences and has a major impact on the quality of life which detrimentally affects future health and education. Finally, ineffective management strategies such as increasing fiber and water in the diet, and short duration of treatment owing to the fear that long-term laxative treatment leads to colonic dysfunction, interfere with effective therapeutic strategies. Conclusions: It is apparent that myths and misconception often lead to wrong assumptions regarding the distribution of the disease, its etiology, pathophysiology, and management leading to ordering incorrect investigations and ineffective therapeutic strategies while spending large sums of public funds unnecessarily. Poorly treated constipation leads to deleterious psychological consequences predisposing children to develop significant psychological damage and bowel dysfunctions. This review aims to challenge these myths about various elements of constipation by exploring the existing literature and encouraging clinicians to have a fresh look at old concepts that could interfere with the well-being of children with constipation. What is Known: • Childhood constipation is a growing problem in the world leading to significant suffering and high healthcare expenditure • Myths and misconceptions lead to poor management strategies causing psychological and bowel damage What is New: • Organic, systemic, and bowel disorders leading to constipation are uncommon, and in the majority, it arises due to deliberate fecal withholding and most investigations ordered by clinicians are not very helpful in the management • Most non-pharmacological interventions are not effective in the day-to-day management of childhood constipation. The use of laxatives is considered to be the first-line management strategy.Item Efficacy and safety of oral hydroxyurea in transfusion-dependent β-thalassaemia: a protocol for randomised double-blind controlled clinical trial(BMJ Publishing Group Ltd., 2020) Yasara, N.; Wickramarathne, N.; Mettananda, C.; Manamperi, A.; Premawardhena, A.; Mettananda, S.INTRODUCTION: Despite being one of the first diseases to be genetically characterised, β-thalassaemia remains a disorder without a cure in a majority of patients. Most patients with β-thalassaemia receive only supportive treatment and therefore have a poor quality of life and shorter life spans. Hydroxyurea, which has shown to induce fetal haemoglobin synthesis in human erythroid cells, is currently recommended for the treatment of sickle cell disease. However, its clinical usefulness in transfusion-dependent β-thalassaemia is unclear. Here, we present a protocol for a randomised double-blind controlled clinical trial to evaluate the efficacy and safety of oral hydroxyurea in transfusion-dependent β-thalassaemia. METHODS AND ANALYSIS: This single-centre randomised double-blind placebo-controlled clinical trial is conducted at the Thalassaemia Centre of Colombo North Teaching Hospital, Ragama, Sri Lanka. Adult and adolescent patients with haematologically and genetically confirmed transfusion-dependent β-thalassaemia are enrolled and randomised into the intervention or control group. The intervention group receives oral hydroxyurea 10-20 mg/kg daily for 6 months, while the control group receives a placebo which is identical in size, shape and colour to hydroxyurea without its active ingredient. Transfused blood volume, pretransfusion haemoglobin level, fetal haemoglobin percentage and adverse effects of treatment are monitored during treatment and 6 months post-treatment. Cessation or reduction of blood transfusions during the treatment period will be the primary outcome measure. The statistical analysis will be based on intention to treat. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Ethics Committee of Faculty of Medicine, University of Kelaniya (P/116/05/2018) and the trial is approved by the National Medicinal Regulatory Authority of Sri Lanka. Results of the trial will be disseminated in scientific publications in reputed journals.Item Quality of Life in children with functional constipation: A systematic review and meta-analysis(Elsevier-Mosby, 2019) Vriesman, M.H.; Rajindrajith, S.; Koppen, I.J.N.; van Etten-Jamaludin, F.S.; van Dijk, M.; Devanarayana, N.M.; Tabbers, M.M.; Benninga, M.A.OBJECTIVE:To systematically review the literature on health-related quality of life (HRQoL) in children with functional constipation and to identify disease-related factors associated with HRQoL.STUDY DESIGN:The Pubmed, Embase, and PsycINFO database were searched. Studies were included if they prospectively assessed HRQoL in children with functional constipation according to the Rome criteria. Articles were excluded if patients had organic causes of constipation and if HRQoL was only assessed after successful therapeutic interventions. A meta-analysis was performed calculating sample size-weighted pooled mean and SD of HRQoL scores. The quality of the studies was also assessed.RESULTS:A total of 20 of 2658 studies were included, providing HRQoL data for 2344 children. Quality of evidence was considered to be poor in 9 of the 20 studies (45%); 13 of the 20 studies reported sufficient data to be included in the meta-analysis. Pooled total HRQoL scores of children with functional constipation were found to be lower compared with healthy reference samples (65.6 vs 86.1; P < .01). Similar HRQoL scores were found according to self-report and parent proxy report. Hospital-based studies reported lower HRQoL scores as compared with community-based studies. Two studies reported on HRQoL scores of children with and without fecal incontinence, but no significant difference was found.CONCLUSIONS:HRQoL is compromised in children with functional constipationItem Erectile dysfunction among male patients diagnosed with schizophrenia being treated with antipsychotic medication, and the impact on quality of life(Sri Lanka College of Psychiatrists, 2018) Rowel, W. W. J. S. M .; Liyange, U. L. N. S.; Hewawitharana, U. H.; Dayabandara, M.; Rodrigo, A.INTRODUCTION:Erectile dysfunction is a distressing side effect of antipsychotics, which leads to poor medication compliance and poor quality of life. There is a scarcity of studies on antipsychotic-induced sexual dysfunction in Sri Lanka. We assessed the prevalence of erectile dysfunction among patients with schizophrenia who have been prescribed antipsychotic medication. METHODS : A cross sectional, descriptive study was conducted among patients attending the outpatient clinics of Colombo North Teaching Hospital and National Hospital, Sri Lanka. The five item International Index for Erectile Dysfunction, Erection Hardness Score and World Health Organization Quality of Life Brief Scale were used to assess erectile dysfunction and quality of life. RESULTS: Of the 102 patients in the study, 80 (79%) were found to have erectile dysfunction. The largest proportion of erec tile dysfunction was seen in patients who were prescribed clozapine (87.9%), followed by risperidone (82.1%), olanzapine (73.9%) and fluphenazine (68.8%). There was no significant correlation between erectile dysfunction and quality of life. None of the patients had initiated a discussion about sexual side effects, while only 8.3% reported that their psychiatrist had inquired about the sexual dysfunction. CONCLUSIONS: The results of this study suggest that sexual dysfunction is a common but often overlooked phenomenon among patients with schizophrenia. This study highlights the need for Sri Lankan psychiatrists to explore sexual problems in this cohort of patients.Item Cost evaluation, quality of life and pelvic organ function of three approaches to hysterectomy for benign uterine conditions: study protocol for a randomized controlled trial(BioMed Central, 2017) Ekanayake, C.; Pathmeswaran, A.; Kularatna, S.; Herath, R.; Wijesinghe, P.BACKGROUND: Hysterectomy is the commonest major gynaecological surgery. Although there are many approaches to hysterectomy, which depend on clinical criteria, certain patients may be eligible to be operated in any of the several available approaches. However, most comparative studies on hysterectomy are between two approaches. There is also a relative absence of data on long-term outcomes on quality of life and pelvic organ function. There is no single study which has considered quality of life, pelvic organ function and cost-effectiveness for the three main types of hysterectomy. Therefore, the objective of this study is to provide evidence on the optimal route of hysterectomy in terms of cost-effectiveness by way of a three-armed randomized control study between non-descent vaginal hysterectomy, total laparoscopic hysterectomy and total abdominal hysterectomy. METHODS: A multicentre three-armed randomized control trial is being conducted at the professorial gynaecology unit of the North Colombo Teaching Hospital, Ragama, Sri Lanka and gynaecology unit of the District General Hospital, Mannar, Sri Lanka. The study population is women needing hysterectomy for non-malignant uterine causes. Patients with a uterus > 14 weeks, previous pelvic surgery, those requiring incontinence surgery or pelvic floor surgery, any medical illness which caution/contraindicate laparoscopic surgery and who cannot read and write will be excluded. The main exposure variable is non-descent vaginal hysterectomy and total laparoscopic hysterectomy. The control group will be patients undergoing total abdominal hysterectomy. The primary outcome is time to recover following surgery, which is the earliest time to resume all of the usual activities done prior to surgery. In total, 147 patients (49 per arm) are needed to have 80% power at α-0.01 considering a loss to follow-up of 20% to detect a 7-day difference between the three routes; TLH versus TAH versus NDVH. The economic evaluation will take a societal perspective and will include direct costs in relation to allocation of healthcare resources and indirect costs which are borne by the patient. A micro-costing approach will be adopted to calculate direct costs from the time of presentation to the gynaecology clinic up to 6 months after surgery. Incremental cost-effectiveness ratios (ICER) will be obtained by calculating the incremental costs divided by the incremental effects (time to recover and QALYs gained) for the intervention groups (NDVH and TLH) over the standard care (TAH) group. DISCUSSION: The cost of the procedure, quality of life and pelvic organ function following the three main routes of hysterectomy are important to clinicians and healthcare providers, both in developed and developing countries.Item Quality of life and impact of bile reflux after retro colic retro gastric gastrojejunostomy in Whipple surgery(Biomed Central, 2017) Siriwardana, R.C.; Lokubandara, R.W.M.A.; Hewavisenthi, S.J.de S.; Liyanage, S.K.; Jayatunga, D.S.P.; Liyanage, C.A.H.Background: Delayed gastric emptying and bile reflux are common concerns in long-term survivors after Whipple surgery. The study was designed to assess modified retro colic retro gastric gastrojejunostomy in reducing macro and microscopic bile reflux and impact on dyspepsia related quality of life in long-term survivors. Methods: Out of 43 patients operated, 23 long-term survivors were included. All underwent gastroscopy and bile reflux was grouped as normal, yellowish bile lakes and presence of greenish bile lakes. Six standard gastric biopsies were taken. Microscopic bile reflux index (BRI) was calculated and a score more than 14 was considered significant. Validated Nepean dyspepsia index-short form (NDI-SF) was used to assess the severity of dyspepsia-related quality of life and compared with age and gender-matched control. Results: The median age was 48 (21–70) years. Median survival of the group was 37 months (6–40). Endoscopically, 20/23 (87%) had macroscopic bile reflux (74% yellowish bile lakes, 13% greenish bile lakes). None had stomal ulcers or macroscopic inflammation. Mean bile reflux index score was 9.7 (range 1.77–34). Mean NDI–SF score of Whipple group was 23.1 (SD 8.88). In controls, mean score was 19.9 (SD 8.23), showing no significant difference (p = 0.245). Conclusions: Though there was macroscopic bile reflux, clinical symptoms and microscopic changes were minimal. The modified technique had good long-term results.Item Physical, psychological, and social aspects of Quality of Life in filarial lymphedema patients in Colombo,Sri Lanka(SAGE Publishing, 2015) Wijesinghe, R.S.; Wickremasinghe, A.R.Quality of life (QOL) was assessed in 141 filarial lymphedema patients and 128 healthy people in the Colombo district, Sri Lanka, by administering modified, translated, and validated (in Sri Lanka) versions of the Short Form 36 health survey questionnaire (SF-36) and the 30-item General Health questionnaire (GHQ-30). The GHQ-30 assesses the current mental health status. The SF-36 measures health on 8 multi-item dimensions covering functional state, well-being, and overall evaluation of health (physical functioning, role limitations resulting from physical health problems, role limitations resulting from emotional problems, energy/fatigue, emotional well-being, social functioning, pain and general health). By SF-36, patients experienced poorer physical functioning, more role limitations resulting from physical health conditions, less emotional well-being, poorer social functioning, and more pain than healthy individuals. By GHQ-30, mental well-being of healthy controls was significantly better than that of patients. The significant difference in the QOL as perceived by filarial lymphedema patients and healthy individuals reiterates the importance of morbidity control in patients affected by this disease.Item Functional gastrointestinal diseases in children: facing the rising tide(Wiley-Blackwell, 2013) Rajindrajith, S.; Devanarayana, N.M.No Abstract availableItem Biofeedback with and without surgery for fecal incontinence improves maximum squeeze pressure, saline retention capacity and quality of life(Springer India, 2008) Munasinghe, B.N.L.; Rathnayaka, M.M.G.; Parimalendran, R.; Kumarage, S.K.; de Zylva, S.; Ariyaratne, M.H.J.; Deen, K.I.Item Modified Dermatology Life Quality Index as a measure of quality of life in patients with filarial lymphoedema(Oxford University Press, 2007) Chandrasena, T.G.A.N.; Premaratna, R.; Muthugala, M.A.R.V.; Pathmeswaran, A.; de Silva, N.R.The quality of life (QoL) and correlates of the QoL of lymphoedema patients attending filariasis clinics and a hospital outpatient department were studied using a Life Quality Index (LQI) in a region endemic for Bancroftian filariasis in Sri Lanka. The index was derived by modifying a previously validated Dermatology Life Quality Index (DLQI) to focus on the oedematous limb rather than the skin. The index was scored from 0 (normal) to 30 (severely affects QoL). Lymphoedema was graded using criteria recommended by the WHO. Another semi-structured questionnaire was used to assess the patient's socioeconomic status, frequency of acute adenolymphangitis attacks (ADLA) and measures practiced for morbidity control. Ninety-one patients (62 females, 29 males; mean age 50.4 years) were studied. A single lower limb, both lower limbs or a single upper limb were affected in 78 (85.7%), 10 (11.0%) and 3 (3.3%) patients, respectively. The severity of lymphoedema ranged from stage 1 (mild) to stage 6 (severe). The mean LQI was 8.2 (SD 5.2, range 0-20). The modified DLQI scores showed a significant positive correlation with severity of lymphoedema and a negative correlation with age (R=0.59 and R=-0.1, respectively). The frequency of ADLAs correlated with an increased modified DLQI score. Local pain, embarrassment and limitations of physical activities were the most distressing aspects of lymphoedema. Disease severity and early onset lymphoedema were found to be significantly associated with poorer QoL in filarial lymphoedema.
