Item Contribution of the private sector healthcare service providers to malaria diagnosis in a prevention of re-introduction setting(BioMed Central, 2016) Fernando, S.D.; Dharmawardena, P.; Epasinghe, G.; Senanayake, N.; Rodrigo, C.; Premaratna, R.; Wickremasinghe, R.BACKGROUND: Sri Lanka is currently in the prevention of re-introduction phase of malaria. The engagement of the private sector health care institutions in malaria surveillance is important. The purpose of the study was to determine the number of diagnostic tests carried out, the number of positive cases identified and the referral system for diagnosis in the private sector and to estimate the costs involved. METHODS: This prospective study of private sector laboratories within the Colombo District of Sri Lanka was carried out over a 6-month period in 2015. The management of registered private sector laboratories was contacted individually and the purpose of the study was explained. A reporting format was developed and introduced for monthly reporting. RESULTS: Forty-one laboratories were eligible to be included in the study and 28 participated by reporting data on a monthly basis. Excluding blood bank samples and routine testing for foreign employment, malaria diagnostic tests were carried out on 973 individuals during the 6-month period and nine malaria cases were identified. In 2015, a total of 36 malaria cases were reported from Sri Lanka. Of these, 24 (67 %) were diagnosed in the Colombo District and 50 % of them were diagnosed in private hospitals. CONCLUSIONS: An equal number of cases were diagnosed from the private sector and government sector in the Colombo District in 2015. The private sector being a major contributor in the detection of imported malaria cases in the country should be actively engaged in the national malaria surveillance system.Item Does pralidoxime affect outcome of management in acute organophosphorus poisoning?(Lancet Publishing Group, 1992) de Silva, H.J.; Wijewickrema, R.; Senanayake, N.Acute organophosphorus (OP) poisoning is usually treated with atropine plus cholinesterase reactivators such as oximes, but controlled trials to assess the efficacy of oximes in OP poisoning have not been done. A period when the acetyl cholinesterase reactivator pralidoxime chloride was not available in Sri Lanka gave us the opportunity to compare atropine alone for treatment of moderate to severe OP poisoning (21 patients) with atropine plus pralixodime (24 patients). Outcome, as assessed clinically, was similar in the two groups. These results cast doubt on the necessity of cholinesterase reactivators for treatment of acute OP poisoning.
