Item Correlation between medical students approach to learning and per-formance in physiology examinations(University of Kelaniya, Sri Lanka, 2004) Devanarayana, N.M.; Medagoda, K.; Rodrigo, U.; Jayasuriya, I.; Dissanayake, A.S.Abstract availableItem Is problem based learning (PBL) a way forward in undergraduate medical education? Results of a pre & post PBL assessment?(University of Kelaniya, Sri Lanka, 2003) Athukorala, A.D.S.P.K.; Devanarayana, N.M.; Medagoda, K.; Ferdinandis, H.; Dissanayake, A.S.; de Silva, D.C.Abstracts availableItem Cardiovagal autonomic functions in children with abdominal pain predominant functional gastrointestinal disorders(University of Kelaniya, 2013) Karunanayake, A.; Devanarayana, N.M.; Rajindrajith, S.Background: About 12% of Sri Lankan children suffer from abdominal pain predominant functional gastrointestinal disorders (AP-FGD). Autonomic dysfunction is believed to be involved in the development of symptoms in patients with AP-FGD. The objective of this study is to assess the cardiovagal autonomic functions among children with AP-FGD. Methods: Twenty five children with AP-FGD age 5 – 12 years (mean age 8 years, SD 2.27 years) were part of the study. There were 12 girls and 13 boys. Autonomic dysfunction related symptoms were recorded using an interviewer-administered, validated questionnaire. Eleven autonomic parameters were obtained while subjecting children to four non invasive, bedside, autonomic function tests; assessment of blood pressure response to standing, heart rate response to standing, heart rate response to deep breathing and heart rate response to Valsalva manoeuver. Results were compared with age, sex, and matched with twenty one healthy children’s autonomic values [mean 8.9 years, SD 1.8 years]. Results: Autonomic dysfunction related symptoms were found among 4 children with AP-FGD (16%). Resting heart rate (86b/min vs. 91b/min in controls), supine systolic blood pressure (111mmHg vs 97mmHg), supine diastolic blood pressure (70mmHg vs 61mmHg) were significantly higher in children with AP-FGD compared with controls (P < 0.05). Conclusion: The children with AP-FGD may have autonomic abnormalities restricted to sympathetic division of the autonomic system.Item Recurrent Abdominal Pain Syndrome in Children is a Significant Burden on Health Care System of Sri Lanka(University of Kelaniya, 2006) Devanarayana, N.M.; de Silva, D.G.H.; de Silva, H.J.Background and objectives – Recurrent abdominal pain (RAP) is a common problem in Sri Lanka affecting more than 10% of children and adolescents. There have been relatively few studies on health care utilization in RAP and they have shown health care consultation of 8-48% in affected children. Methods- RAP patients identified during a school survey were recruited. RAP was defined according to Apley’s criteria; ‘at least three episodes of abdominal pain, severe enough to affect activities, over a period of not less than three months’. Information regarding health care consultations were obtained using parental questionnaire and confirmed during a clinical interview. A child taken to see a doctor due to abdominal pain at least once during the year 2001 was considered as a health care consulter. Results- Seventy seven with RAP were recruited in the study. Fifty five (70.1%) were health care consulters. Of them 6 (9.1%) were given in-patient care and 49 (90.9%) were managed by hospital out patient clinics or general practitioners. Average number of consultation was 2.0 visits per year (SD 2.5). Twenty three (29.1%) had not taken treatment even though they suffer from recurrent attacks of pain. Health care consultation was significantly high when the child with RAP was the eldest (p=0.0470), a good academic achiever (p=0.0210) and had pain associated with vomiting (p=0.00741). Conclusions- The health care consultation among Sri Lankan children with RAP is higher than reported from other countries. RAP is a significant burden on health care system of the country.Item Low fat diet and childhood functional recurrent abdominal pain syndrome: a preliminary study(Research Symposium 2009 - Faculty of Graduate Studies, University of Kelaniya, 2009) Devanarayana, N.M.; Rajindrajith, S.; de Silva, D.G.H.; de Silva, H.J.Background: There is a lack of high quality evidence on the effectiveness of dietary interventions on childhood recurrent abdominal pain (RAP). Fat is well known to affect gastrointestinal motility, but to date no studies have evaluated the value of low fat diets in RAP. Methods: Forty two children with functional RAP [19 (45.2%) males, 5-15 years] were recruited after electrogastrography (EGG), gastric emptying (GE), antral motility and oro-caecal transit (OCT) studies. Subjects were randomly allocated to low fat diet (group 1) and normal diet (group 2). Dietary instructions were provided in a diary and during an interview and energy and fat intake were recorded. Patients consumed allocated diet for 4 weeks. They were assessed before intervention and at 4 weeks using global seven-point scales for severity of symptoms and changing symptoms. Results: At one month, 12 (57.1%) patients in group 1 and 13 (61.9%) in group 2 had improvement of symptoms (P=0.759). The average scores obtained for pain severity, change in symptoms and frequency of episodes were not different between two groups (P=0.62). More patients with delayed GE had improvement in symptoms [9 (82%)] following a low fat diet compared to those with normal GE and OCT [3 (30%)] (P=0.024, power of the study 86%, at significant level of 0.05). Conclusions: Low fat diet seems to be beneficial for the subgroup of functional RAP children with delayed gastric emptying and intestinal transit while it has no significant therapeutic effect on patients with normal gastrointestinal motility.
