RESUMO

Introduction: We recently developed a scoring system for diagnosis of acute appendicitis. This study prospectively evaluates the Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) score for the diagnosis of acute appendicitis in patients presenting to the Accident & Emergency department or the Surgical wards with right iliac fossa pain. Materials and Methods: From November 2008 to April 2009, consecutive patients presenting to the Accident & Emergency department or the surgical wards with right iliac fossa pain were recruited for the study. The RIPASA score was applied but the decision for radiological investigations or emergency appendicectomy was made based on clinical judgement. Receiver operating curve (ROC), sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the new scoring system were derived. Ethical approval for the study was obtained from the Medical & Health Review Ethics Committee. Results: Within six months, 144 consecutive patients with a mean age of 29.5 ± 13.3 yrs were recruited to the study. Ninety-eight patients underwent emergency appendicectomy of which 79 were confirmed histologically for acute appendicitis. The observed negative appendicectomy rate was 19.4%. The optimal cut-off threshold score from the ROC was 7.5, with a sensitivity of 97.5%, specificity of 81.8%, PPV of 86.5%, NPV of 96.4% and a diagnostic accuracy of 91.8%. The predicted negative appendicectomy rate was 13.5%, which is a 5.9% reduction from the observed rate of 19.4% (p=0.3). Conclusion: The RIPASA score is a more suitable appendicitis scoring system developed for our local settings with a population that is reflective of our region in South-east Asia and has high sensitivity, specificity and diagnostic accuracy.

RESUMO

A simple health promotion message administered by village midwives raised bednet usage to over 60% in trial hamlets in north Shan State, Myanmar. Treatment of the nets in the study villages produced a reduction in malaria cases. Most villagers were prepared to buy their nets at market prices and were willing to pay for the cost of re-treatment of nets, but very poor, members of the Wa ethnic group required a half-price subsidy for them to afford them. The use of insecticide treated bednets was felt to be appropriate for undeveloped and remote areas of the country where malaria control was difficult.

RESUMO

A cross sectional study was carried out in a rural area of Myanmar to identify malaria patients' acceptance of artesunate plus mefloquine drug combination and to determine the cost borne by patients. The majority (88.5%) preferred this new regimen rather than the other ones they had used before; conviction of drug efficacy was the reason given for the preference by most of them. Traveling on foot to rural health centers or a health assistant's residence for getting the drugs was found to be the main route. Average cost incurred by a patient to get the drug was found to be 274.22 Kyats. Among the cost items, drug cost was the highest item that they had used.

RESUMO

The study was intended to develop a simple and reliable in vivo field test for monitoring of sensitivity of P.falciparum to antimalarials. The test is to be used as a built in sustainable monitoring system and applied at regular frequencies to provide guidance in developing a country-wide antimalarial drug policy. The study was conducted as a hospital based study in Mon State in Mudon, Kamawet and Pa-auk hospitals. The criteria matched malaria patients were treated with standard dosages of chloroquine, sulfadoxine-pyrimethamine and mefloquine and blood films were taken on days 0, 2, 3, 4, 7, 14 and 28. The assessment of the in vivo drug response of P.falciparum on days 2, 3 and 4 were compared with WHO standard 28 days and 7 day tests. The following successful tests were carried out for 7 days with different antimalarials: 171 tests with chloroquine and sulfadoxine-pyrimethamine and 167 tests with mefloquine. Tests were also carried out for 28 days: 59 tests with chloroquine, 77 tests with sulfadoxine-pyrimethamine and 78 tests with mefloquine. The results found that 3 day tests, taking blood films on days 0 and 3, can be reliably used as an adjunct to 28-day tests. Since the test is simple and can be used extensively and sustainably throughout the country and the results are applicable to be used for epidemiological purposes, the method is suggested for use as a built-in monitoring method for the malaria control program.
