Item Sequelae of BCG vaccination and effects of cleaning vaccine site with alcohol(Sri Lanka Medical Association, 2012) Perera, P.; Samaranayaka, G.; Samaranayaka, R.; Ranathunga, N.INTRODUCTION: In Sri Lanka, BCG vaccine is given during neonatai period. There are many myths regarding BCG vaccine among general public and sequelae of vaccination is not well documented in medical literature. AIMS: Objectives of this study were to describe the sequelae of BCG vaccination when given at neonatal period and to find out whether cleaning the vaccine site with 70% alcohol, affect its potency. METHODS: A prospective observational study was carried out at Ragama teaching hospital and 2 private hospitals in Gampaha district. 125 babies each from government and private sector were recruited for the study with the consent from parents. Vaccine was administered in the morning as well as evening, as required by the patient, by a consultant Paediatrician. Vaccine site was cleaned with 70 % alcohol and allowed to dry before vaccination. All babies were bathed on same day. Babies were followed up periodically until a scar was detected. RESULTS: 182 babies completed the follow up and all babies developed a scar. Time taken for a reaction varied but all babies had a reaction by 8 weeks and a scar by 14 weeks. 6 babies had fever within one week of vaccination but it was due to feeding failure or sepsis. None had adverse reactions attributable to the vaccine. CONCLUSIONS: Cleaning the vaccine site with alcohol does not affect the potency of BCG vaccine. Proper technique of administration is important for successful vaccination. Time of vaccination and bathing had no effect on efficacy or side effects.Item Dental hygiene practices and the pattern of dental caries in preschool children in Ragama(Sri Lanka Medical Association, 2012) Perera, P.; Abeweera, N.; Fernanado, M.; warnakulasuria, T.W.; Ranathunga, N.INTRODUCTION: Dental caries is a common problem among preschool children, but often neglected as deciduas teeth are replaced later by permanent teeth. However, for many reasons, protecting deciduas teeth is very important. AIMS: The objectives of this study were to describe the prevalence of dental caries among preschool children and assess the utilization of dental care facilities. METHODS: A descriptive cross sectional study was done between August 2010 and October 2010 at child welfare clinics held in the Ragama MOH area. Consecutive children aged between 2 and 5 years attending the clinics were recruited with the consent of parents. An interviewer administered questionnaire was used to obtain data and the mouth was examined for caries. Total decayed-missing-filled (dmft) score and significant caries index (SIC) were calculated to describe the prevalence of dental caries. Care index was calculated to describe the use of dental services. RESULTS: Out of 410 children recruited, none had routine visits to a dentist. Though practices related to brushing teeth were satisfactory, 37.8% children in the study sample had caries. This increased to 68.8% by 5 years of age. Mean dmft score for the whole sample was 1.41 and SIC index was 4.09. The Care index was 4.72. The dmft score in girls was higher than boys. Incisors of the upper jaw were the mainly affected teeth. CONCLUSIONS: Prevalence of dental carries among this cohort of Sri Lankan preschool children is very high. The level of dental care for preschool children at present appears to be unsatisfactory.Item Feeding practices of children attending well baby clinics in Ragama MOH area: a descriptive cross sectional study(Sri Lanka Medical Association, 2011) Perera, K.P.J.; Fernando, M.; Warnakulasuria, T.; Ranathunga, N.INTRODUCTION AND OBJECTIVES: Feeding during early childhood is important for growth and health. Objectives of this study were to evaluate the current feeding practices during first few years of life among Sri Lankan children. METHODS: A descriptive cross sectional study conducted in Ragama MOH area during the period of 10th august 2010 and 30th October 2010. 410 children between 2 -5 years of age, attending well baby clinics were included in the study. Interviewer administered questionnaire was used to collect data regarding socio-demographic characteristics and feeding practices. Open ended questions were used. SSPS version 16 was used for data analysis. RESULTS: The study population consisted of 208 boys and 202 girls. 62.2% children were exclusively breastfed for 6 months. 351 have received formula milk. 61 had formula milk started before the age of 6 months and 212 by one year. 330 children had sugar added to formula milk. 144 of them had sugar added within first year. 29 children had complementary food started before 4 months. 294 mothers continued to breastfeed beyond 2 years and 41.6% of them were breast feeding at regular intervals. 82.5% children were receiving overnight feeding either as breast milk or formula beyond 2 years. . CONCLUSIONS: Though high rate of exclusive breast feeding is prevalent in Sri Lanka, there seem to be other issues related to feeding. Too early introduction of complementary food, adding sugar to formula, prolonged breast feeding too frequently and prolonged overnight feeding are among them.
