Item Diagnostic overlap between adolescent affective instability in borderline personality and juvenile bipolar disorder in Sri Lanka(Sri Lanka College of Psychiatrists, 2019) Chandradasa, M.; Fernando, W.K.T.R.; Kuruppuarachchi, K.A.L.A.Borderline personality disorder (BPD) and bipolar disorder (BD) could present a diagnostic challenge in the adolescent due to the presence of overlapping symptoms such as impulsivity, affective instability, and sexual arousal. Of these symptoms, affective instability is a central feature of BPD, and there is a rapid shift from the neutral affect to an intense affect, and this is associated with a dysfunctional modulation of emotions. We describe three Sri Lankan adolescents presenting with affective instability, treated with psychopharmacological agents as for BD. While BPD is characterized by transient mood shifts induced by interpersonal stressors, in BD, there are sustained mood changes. A longitudinal assessment of the symptomatic profile and collateral information clarified the diagnosis as being BPD. An examination of the nature of affective instability is vital for a proper diagnosis and provision of evidence-based treatment.Item Examining depression and quality of life in patients with thalassemia in Sri Lanka(Wolters Kluwer - Medknow, 2019) Patel, P.; Beamish, P.; da Silva, T.L.; Kaushalya, D.; Premawardhena, A.; Williams, S.; Ravindran, A.V.BACKGROUND: With more effective treatments and improved outcomes in thalassemia, there is increasing focus on its psychological sequelae. Most published data on this topic are from high income countries and much less so from low and middle income countries, where thalassemia is more prevalent. AIM: The aim of this study was to systematically evaluate the psychiatric morbidity and quality of life in relation to demographic and illness related variables among Sri Lankan patients with thalassemia. METHODS: This cross sectional investigation was conducted at the University of Kelaniya Teaching Hospital in Sri Lanka. Patients with all forms of thalassemia, over 12 years of age, and in stable medical condition (n = 120) were recruited. Assessment tools included a general demographic questionnaire, the Beck Depression Inventory II, and the World Health Organization Quality of Life Measure–Brief. Statistical analysis was conducted using linear regressions, Chi squares, and analyses of variance. RESULTS: Lack of family support, longer duration of inpatient admission, and female gender were associated with higher depression scores and reduced quality of life. Environmental and social quality of life were positively correlated with levels of peer support in males, while increased support from religion correlated with lower depression scores and higher satisfaction with environmental and psychological quality of life in women. There was no association between the type of thalassemia and either depression or quality of life measures. CONCLUSION: Several factors may influence the psychological state and well being of patients with thalassemia in Sri Lanka. Specific service innovations (some gender specific) may help to address these factors to improve treatment outcome and well being.Item A retrospective analysis of the prevalence of heart disease in pregnancy – a Sri Lankan experience(Wiley-Blackwell, 2015) Motha, C.; Palihawadana, T.; Dias, T.; Thulya, S.D.; Godage, T.INTRODUCTION: With improvement in obstetric care, the burden due to direct causes of maternal mortality has declined bringing medical conditions to the forefront. Heart disease in pregnancy remains a major cause of maternal morbidity and mortality in Sri Lanka. In the absence of a robust pre-conception care programme, many women with pre-existing heart disease embark on pregnancy unaware of the underlying abnormalities. This study was aimed at describing the proportion of women with heart disease, the type of heart disease and the time of detection in this population. METHODS: The North Colombo Obstetric database (NORCOD) records data for all women who deliver at the university obstetric unit of the North Colombo Teaching hospital, Ragama, Sri Lanka. Details of women delivered between March and August 2014 were used in a retrospective analysis. Data on booking screening, and pregnancy care with regard to heart disease were analysed. RESULTS: A total of 1830 pregnancies were included. Fifty (2.7%) were complicated with heart disease. 15 (0.8%) patients were known to have pre-existing heart disease at the time of booking. They included 10 with congenital heart disease (treated ASD in 3, untreated ASD in 1, untreated VSD in 1, ligated PDA in 1 and mitral valve disease in 4) and 5 acquired heart disease due to rheumatic heart disease. A cardiac murmur on auscultation was detected in 61 women (3.3%) at their booking screening. 26 (42.6%) of them were found to have an underlying cardiac lesion. The commonest lesion was isolated mitral valve prolapse (n = 11), followed by mitral regurgitation associated with mitral valve prolapse (MVP) in 10, tricuspid regurgitation (TR) in 3, and one each of ASD and VSD. Nine others were found to have underlying cardiac lesion at assessment during pregnancy, in the absence of any abnormality at booking. These included 6 with MVP, 2 with mitral regurgitation (MR) with MVP, and one with MR. CONCLUSION A significant proportion of women with cardiac abnormalities (70%) were detected during pregnancy. This highlights the importance of pre-conception care with screening in this population. While booking screen was able to identify a majority of patients, some were detected only during subsequent assessment. Clinical vigilance throughout pregnancy facilitates such detection.Item Diabetes mellitus in pregnancy – a Sri Lankan experience(Wiley-Blackwell, 2015) Dias, T.; Palihawadana, T.; Motha, C.; Thulya, S.D.INTRODUCTION Diabetes mellitus in pregnancy carries high perinatal morbidity/mortality and maternal morbidity. Only a proportion of women would have pre-existing diabetes mellitus with the majority developing gestational diabetes (GDM). The burden of diabetes in pregnancy is expected to increase in Sri Lanka as obesity is high among pregnant population. Aims of this study were to look at the prevalence, risk factors and complications of diabetes in pregnancy. METHODS The North Colombo Obstetric database (NORCOD), which records pregnancy data of all women delivering at the university obstetric unit of the North Colombo Teaching hospital, Ragama, Sri Lanka, was used for retrospectively analysis. 1830 deliveries between March and August 2014 were included. Those with incomplete data were excluded. Details regard to prevalence, associated risk factors and complications were identified. RESULTS: Diabetes mellitus complicated 130 (7.1%) pregnancies. This consisted of 26 with pre-existing disease and 104 with GDM. A positive family history in first degree relative (OR 7.87, 95% CI 5.08–12.1), and a BMI of >23 kg/m2 (OR 2.68 95% CI 1.75–4.11) were associated with development of GDM. The mean (SD) age was significantly higher among women who developed GDM compared to those did not (32.1 (4.76) versus 28.7 years (4.7), P = 0.03 respectively). The mean (SD) postprandial blood sugar (PPBS) estimate done in the first half of the pregnancy was significantly higher among women who developed GDM later in pregnancy compared to those who did not (120 (39.2) versus 95 mg/dL (14.6), P < 0.0001 respectively). Hypertensive disorders of pregnancy was significantly associated with diabetes in pregnancy (OR 2.39 95% CI 1.49–3.83) and a birthweight of >3 kg at term (OR 1.63 95% CI 1.11–2.40). CONCLUSION: Diabetes mellitus complicates a significant number of pregnancies. Pre-existing diabetes constitutes one fifth of thesepregnancies, highlighting the importance of provision of preconception care to women contemplating pregnancy. A positive family history increases the risk of GDM by nearly 8 fold. Abnormal PPBS results in early part of pregnancy, in women who later develop GDM suggest the presence of abnormal glucose homeostasis in this group even at early stages of pregnancy. This has the potential for developing in to a test of early detection of GDM in pregnancy.Item First series of laparoscopic sleeve gastrectomy in Sri Lanka-technical feasibility and outcome in a resource poor setting in asia.(New York; Springer, 2014) Wijeratne, T.K.; Bulugahapitiya, U.; Kumarage, S.; Rajaratnam, H.INTRODUCTION: Morbid obesity and metabolic syndrome are emerging as a major health issues in developing South Asian countries. Laparoscopic Sleeve Gastrectomy (LSG) has been introduced to this region with excellent out comes in controlling morbid obesity and metabolic syndrome. OBJECTIVE(S): Assess the technical feasibility and outcome of LSG as a surgical procedure in a resource poor country in south Asia where Bariatric surgery is still a novel concept. METHOD(S): Prospective Analytical study of the first 15 patients who underwent LSG in a tertiary care hospital in Sri Lanka over 2 years. All data on pre operative, surgical and post operative follow up were recorded in a pre-designed research Performa and all patients were followed up for a minimum period of 6 months by Surgical and Endocrine team. All Surgeries were performed by the same surgeon and the surgical team using total Laparoscopic technique using a 40 F Gastric bougie to standardize the Sleeved stomach. There were 14 females and one male in the study group. Weight range was from 83 to 167 kg with a mean weight of 106.2 kg. Average BMI 45 kg/m2 Results: There were no major complications. The percentage excess weight loss during first 3 months was 28.8 % and at 6 months 42.3 %. Resolution of comorbidities especially Diabetes and Metabolic Syndrome was excellent and one out of two patients who had surgery for subfertility conceived during study period. CONCLUSION(S): LSG can be performed safely in a resource poor setting in south Asia and is effective as a Bariatric surgical procedure for Sri Lankan population.Item Adverse drug reactions in a cohort of Sri Lankan patients with non-communicable chronic diseases(Elsevier, 2017) Wijekoon, C.N.; Shanika, L.G.T.; Jayamanne, S.; Coombes, J.; Dawson, A.BACKGROUND: Adverse drug reactions (ADRs) pose a major problem in medication use. This study was done to describe incidence, nature and associated factors of ADRs in a cohort of Sri Lankan patients with non-communicable chronic diseases (NCCDs). METHODS: The prospective observational data presented here are obtained as a part of a large study conducted in a tertiary-care hospital in Sri Lanka. In-ward patients with NCCDs were recruited systematically using the admission register in the ward as the sampling frame. All ADRs occurred during the index hospital admission and 6-month post-discharge period were detected by active surveillance. RESULTS: 715 patients were studied (females – 50.3%; mean age – 58.3±15.4years). 35.4% were aged ≥65years. Mean number of drugs prescribed per patient was 6.11±2.97. Most prevalent NCCDs were hypertension (48.4%), diabetes (45.3%) and ischemic heart disease (29.4%). 154 ADRs [33 (21.4%) during index hospital admission; 121 (78.6%) during 6-month post-discharge period) were detected involving 112 (15.7%) patients. 51.9%(80/154) of them were potentially avoidable. 47% (73/154) of ADRs were serious adverse events (SAEs); 13 were life threatening, 46 caused hospitalization and 14 caused disability. The most common causes for re-hospitalization due to ADRs were hypoglycemia due to anti-diabetic drugs (17/46), bleeding due to warfarin (6/46) and hypotension due to anti-hypertensives (6/46). ADRs were more common in elderly (34% vs 14.7%, p<0.001), in those who were on ≥5 drugs (25.9% vs 12.7%, p<0.001) and among those with diabetes (28.5% vs 15.6%, p<0.001). CONCLUSIONS : Incidence of ADRs was high in the study population. A large proportion of them were SAEs. The majority of ADRs that required re-hospitalization were caused by widely used drugs and were potentially avoidable. Factors associated with a higher incidence of ADRs were age ≥65years, ≥5drugs in the prescription and presence of diabetes. The healthcare system in the study setting needs improvement in order to minimize ADRs.Item Opportunities for pharmacists to optimise quality use of medicines in a Sri Lankan hospital: An observational, prospective, cohort study(Wiley-Blackwell, 2017) Perera, D.M.P.; Coombes, J.A.; Shanika, L.G.T.; Dawson, A.; Lynch, C.; Mohamed, F.; Kalupahana, N.; de Silva, H.A.; Jayamanne, S.F.; Peters, N.B.; Myers, B.; Coombes, I.D.BACKGROUND: Quality use of medicines (QUM) has been identified as a priority in Sri Lanka. Aim: To identify opportunities to optimise QUM, and evaluate medication appropriateness and medication information exchanged with patients and carers on discharge in a Sri Lankan tertiary care hospital. METHODS: An observational, prospective, cohort study of patients systematically sampled from two medical wards. A research pharmacist determined their pre-admission medication regimen via interview at time of discharge. Issues of poor adherence and discrepancies between the pre- and post-admission medication regimens were recorded. Drug-related problems were categorised into opportunities to optimise drug therapy. The appropriateness of discharge medications was evaluated using a validated tool. The patient or carer was interviewed after discharge regarding the quality of medicine information exchanged in hospital. RESULTS: The 578 recruited patients were taking 1756 medications prior to admission, and 657 (37.4%) of these medications were not continued during admission. Opportunities to optimise drug therapy were identified on 1496 occasions during admission (median, 2.0 opportunities/patient), 215 opportunities, (14.4%) were resolved spontaneously by the medical team prior to discharge. The median score for appropriateness of medications on discharge was 1.5 per patient (interquartile range, 0.0–3.5). Of 427 patients surveyed after discharge, 52% recalled being asked about their medications on admission to hospital, 75% about previous adverse medication reactions and 39% recalled being informed about changes to their medications on discharge. CONCLUSION: Significant opportunities exist for pharmacists to enhance quality use of medicines for patients in the current hospitalbased healthcare system in Sri Lanka. © 2017 The Society of Hospital Pharmacists of Australia.Item Regulation of the medical profession in Sri Lanka: reform is urgently needed(Sri Lanka Medical Association, 2019) de Silva, N.; de Silva, H.No abstract availableItem Evaluation of the undergraduate family medicine programme of Faculty of Medicine, University of Kelaniya: quantitative and qualitative student feedback.(BioMed Central, 2019) Perera, D.P.; Withana, S.S.; Mendis, K.; Kasunjith, D.V.T.; Jayathilaka, W.T.S.; Wickramasuriya, S.BACKGROUND:Worldwide there is an increasing emphasis on the importance of primary care. The ministry of health Sri Lanka issued a directive in 2016 that training of doctors in primary care should be strengthened. Medical students of the Faculty of Medicine, University of Kelaniya follow a 1 month long clinical appointment in family medicine in their fourth year of study. METHODS:Feedback is taken from students on completion of the appointment. Half the students from each group complete a pre tested structured feedback questionnaire that consists of answers to questions based on a likert scale with a space for free comments. The other half provide qualitative feedback. In this evaluation data were gathered from 185 (98%) students from all eight clinical groups throughout the year 2016. Quantitative data were analysed using SPSS version 22. Inductive thematic analysis was used to analyse the qualitative data from the Round Robin activity and free comments from the questionnaire. RESULTS:The qualitative feedback provided a richer indepth overview of student ideas on the appointment compared to the quantitative data. In reflection of a desire for learning to be of relevance students wanted clinically oriented teaching focused on management. They preferred active teaching learning methods such as the opportunity to conduct consultations and receive immediate feedback. Students had a high regard for the teaching sessions by general practitioners at their clinics. The appointment had created an interest in the discipline of family medicine which could have an impact on future choice of career. There were indications to suggest that student attitudes towards patients may have evolved to be more patient centred. Students appreciated the inclusive and low stress ambience of the learning environment. CONCLUSIONS AND RECOMMENDATIONS:Regular evaluation of teaching programmes helps maintain accountability of faculty and paves the way for more student centred teaching through the incorporation of students' views in devising teaching methods. This evaluation found that qualitative feedback provided more descriptive material to reflect on and therefore improve teaching on the programme. It is recommended that more use should be made of qualitative methodologies in programme evaluations.Item Availability of facilities and equipment to provide emergency care in ambulances, which transport patients to the National Hospital of Sri Lanka(Journal of the College of Community Physicians of Sri Lanka, 2018) Nandasena, G.; Abeysena, C.ABSTRACT: Objective To describe available facilities and equipment in ambulances, to provide essential emergency care, which transport patients to the National Hospital of Sri Lanka Methods A descriptive cross-sectional hospital based study was carried out at the National Hospital of Sri Lanka from August to October 2008. All ambulances that arrived at the hospital during the study period with an emergency patient were selected as study sample (n=409). A Check list was used to assess in situ facilities and equipment that should be available for basic life support (BLS) and advanced life support (ALS). Results Most of the ambulances were equipped only with very basic facilities such as wheeled stretcher 95.4% (n=390), ABC fire extinguishers 75.3% (n=308) and warning siren 94.4% (n=386). Among ventilation and air way equipment, ‘oxygen cylinders’ showed highest percentage {68.7%; n=281) of availability in ambulances and oropharyngeal air ways were available only in 4.9% (n=20). Ventilation and air way equipment required for ALS were available only in less than 1% of all ambulances. Among patient assessment equipment, pen lights were available in 19.6% (n=80) and blood pressure apparatus in 2.2% (n=9) of ambulances. Obstetrical supplies, splinting equipment, surgical dressings except bandages, drug delivery devices, intravenous equipment except IV hook were available among < 5% of all ambulances. Most of the ambulances were equipped with safety and accessory equipment, except child safety seat 0.5% (n=2), triage tags 1.7% (n=7) and hack saw 0.7% (n=3), which were available in <2% of all ambulances. Conclusion The facilities and equipment that should be available in both basic and advanced life support ambulances were poor.
