(Sri Lanka Medical Association, 2012) Krishnapradeep, S.; Kumarendran, B.; Bandara, S.
INTRODUCTION: Neonatal hypothermia is known to result in many adverse consequences. Aims: To estimate the incidence and associated factors of neonatal hypothermia METHODS: This cohort study followed up 125 neonates consecutively admitted to Special Care Baby Unit of Teaching Hospital, Peradeniya from November 2011 to January 2012. A paediatric registrar interviewed parents using a structured-questionnaire and direct observation using a check list. On admission, axillary body temperature was measured and graded using WHO classification. Results: Of the 125 neonates, 96 were admitted within first day of birth (78.6%) and 72 had low birth weight (57.6%). Neonates were admitted from operation theater (58, 46.4%), postnatal ward (34, 27.2%) and labour room (23, 18.4%). Median temperature on admission was 36.2 °C with 38.4% having moderate hypothermia (n=48), 19.2% cold-stress (n=24) and none with severe hypothermia. Risk of hypothermia was increased by prematurity (OR = 9.9, 95% CI: 4.2 - 23), low birth weight (OR= 6.8, 3.1 -15.1), being delivered by caesa-pean section (OR=4, 1.8 - 9.1), admission from operation theatre or labour room (OR =9.1, 3.9 - 21.4) and cold delivery room ( p < 0.001). Caesarean rate was higher among neonates admitted to PBU than all the children delivered (OR = 3.35, 2.2 - 5.1). Hypothermia increases risk of poor activity (OR =1.8, 1.4 - 2.4), poor feeding (OR= 7.2, 1.5 - 34.9), poor cry (OR = 1.9, 1.5 - 2.4), respiratory distress (OR= 1.5, 1.1 - 2.0) and hypoglycemia (OR = 1.6, 1.2 - 2.0).
Dengue vector surveillance in a dengue hot-spot in Sri Lanka
(Faculty of Tropical Medicine, Mahidol University, 2007) Sumanadasa, S.D.M.; Hapugoda, M.D.; Perera, D.; Bandara, S.; Mansoor, M.A.; Peris, I.; Abeyewickreme, W.
BACKGROUND: In South Asia, dengue has been declared as one of the most, fast-spreading vector-borne diseases. Therefore, mosquito surveillance is important for early detection of outbreaks along with implementation of prompt control activities. OBJECTIVES: To identify entomological risk factors with regard to transmission of dengue in a dengue hot-spot. Seventy five human dwellings in Vehara in the Kurunegala District of the Western Province were selected based on high disease incidence during 2000-2004, high Aedes as well as human population density and increased building activities. Entomological surveillance was done during May-August, 2007. RESULTS: The house Index ranged from 2.67% to 5.33% for Aedes aegypti while it for Aedes albopictus was 1.33% to 6.60%. The container index ranged from 23.67% to 29.33% for Ae. aegypti and from 1.33% to 18% for Ae. aibopictus. Man biting rates of 0.43-5.78 bites/man/hour were estimated for Ae, aegypti, while it ranged between 0.49 and 1.33 for Ae. aibopictus. The most common breeding place for Aedes species was plastic baskets (16%, n=12). DISCUSSIONS: Vector surveillance showed that the predominant vector species present in the study area was Ae. ageypti. Aedes mosquito larval densities and adult biting rates were sufficient to promote outbreaks of dengue in this study area. Community must be educated regarding effective measures to protect them from dengue. Their cooperation should be elicited in the early detection and elimination of vector species by source reduction, environmental management and personal protection measures.
Surveillance for dengue vector mosquito in Kurunegala district, Sri Lanka
(Elsevier, 2008) Sumanadasa, S.D.M.; Hapugoda, M.D.; Peiris, I.; Perera, D.; Bandara, S.; Mansoor, M.A.C.M.; Abeyewickreme, W.
BACKGROUND: Dengue vector surveillance is an important tool to determine the time and area/s to initiate control action. Our objective was to identify entomological risk factors with regard to transmission of dengue in a dengue hot-spot. METHODS: In the study 75 human dwellings in a dengue hot-spot in the District of Kurunegala was selected based on high disease incidence during 2000—2004, high Aedes as well as human population density and increased building activities. House to house mosquito surveillance was carried out from 08.00 am to 12.00 noon during May—August, 2007. Larvae and adult Aedes mosquitoes were collected indoors and outdoors using normal larval surveillance and human landing diurnal collection techniques respectively. Environmental and sociological data were obtained from households by interviewer administered questionnaires and observations. RESULTS: The house index for Aedes aegypti and Aedes albopictus ranged from 1.33%—6.60% and 2.67%—5.33% respectively. The Breatu index ranged between 23.67%—29.33% for Ae. aegypti and 1.33%—18% for Aedes albopictus. Man biting rates of 0.43—5.78 bites/man/hour were estimated for Ae. aegypti, while it ranged from 0.49—1.33 for Ae. albopictus. The most common breeding place for Aedes species was plastic baskets (16%, n = 12). More than half of the households (61%, n = 45) stored water in large cement tanks for their daily activities. Majority of the group (99%, n = 74) had a basic knowledge on dengue mosquito breeding places (97%, n = 73), their life cycle (95%, n = 71) and mode of transmission (99%, n = 74). Domestic waste of majority of households was carried away daily by the local authorities (n = 69). CONCLUSION: These results suggest that a vector control program should be adopted to reduce Aedes population levels below dengue transmission thresholds. Discarded containers of various types were identified as potential mosquitoes breeding habitats. Therefore, community must be educated on effective vector control measures to contain the transmission levels. © 2008 Elsevier Inc.
