Item Anaemia in children: are we using the correct prevention strategies?(Sri Lanka Medical Association, 2017) Mettananda, S.; de Silva, D.G.H.Item Oro-caecal transit in Sri Lankan children and adolescents with functional recurrent abdominal pain(Wiley Blackwell Scientific Publications, 2008) Devanarayana, N.M.; de Silva, D.G.H.; de Silva, H.J.INTRODUCTION: Recurrent abdominal pain (RAP) is a common paediatric problem. The majority of the affected have no organic pathology. Gastrointestinal motility abnormalities are considered as a possible cause for their symptoms. This study evaluated oro-caecal transit in children and adolescents with functional RAP. METHODS: Thirty one children with functional RAP and 20 healthy children from the same geographical area underwent oro-caecal transit time measurement by lactulose (0.25 g/kg in 10% solution) breath hydrogen test. None had evidence of organic disease, except for one control who had a positive Helicobacter pylori stool antigen test. RESULTS: Oro-caecal transit times could be calculated in 30 patients [10 (33.3%) males, mean age 7.2 years, SD 2.4 years, 12 functional abdominal pain, 8 irritable bowel syndrome, 8 functional dyspepsia, 1 abdominal migraine, 1 non-specific abdominal pain according to Rome III criteria] and 19 controls [10 (52.6%) males, mean age 9 years, SD 2.7 years]. One patient (3%) and 1 control (5%) were non-responders. Oro-caecal transit time was significantly prolonged in patients (median 90 min, range 45–150 min) compared to controls (median 75 min, range 30–105 min) (p = 0.0045). Oro-caecal transit time did not correlate with scores obtained for severity of abdominal pain (r = 0.176, p = 0.354) and had no association with exposure to recent stressful life events (p > 0.05). CONCLUSIONS: Oro-caecal transit time was delayed in children and adolescents with functional RAP. The future studies are needed to confirm the role of delayed oro-caecal transit in generation of symptoms, and to evaluate the therapeutic value of drugs that normalize small intestinal transit.Item Non-accidental injuries to children in Sri Lanka(Sage Publishing, 1988) Chandrasiri, N.; Lamabadusuriya, S.P.; de Silva, D.G.H.No abstract AvailableItem Disaccharidase activities in jejunal fluid(British Medical Association, 1983) Aramayo, L.A.; de Silva, D.G.H.; Hughes, C.A.; Brown, G.A.; McNeish, A.S.Jejunal fluid and mucosal tissue were obtained simultaneously from the same jejunal site in a group of 29 children by a modified biopsy procedure. Lactase, maltase, and sucrase activities were measured in both fluid and mucosal specimens using the same analytical method. The fluid enzyme activities showed highly significant positive correlations with the same enzyme activity in the relevant tissue samples. Relative concentrations of disaccharidase enzymes represented by sucrase: lactase activity ratios also showed a highly significant positive correlation between fluid and tissue. This close relation suggests that the mucosa is the sole or predominant source of disaccharidase activity in the intestinal fluid. The results of kinetic studies comparing tissue and fluid enzyme characteristics also indicate a mucosal origin for the fluid enzyme activities. We conclude that disaccharidase activities in jejunal fluid reflect closely local tissue values and that these measurements may be useful in assessing mucosal enzyme activity in infants in whom jejunal biopsy is not possibleItem The Pattern of rheumatic fever in a paediatric unit in Colombo(Sri Lanka Medical Association, 1980) Soysa, P.E.; de Silva, D.G.H.; Ariyananda, P.L.; de Silva, D.D.No abstract available
