RESUMO
BACKGROUND: Behaviour change communication (BCC) can improve malaria prevention and treatment behaviour. As a one of the activities under Myanmar Artemisinin Resistance Containment (MARC) programme, BCC have been conducting. This study aimed to evaluate the effectiveness of the behaviour change communication and community mobilization activities in MARC zones in Myanmar. METHODS: A cross sectional descriptive survey was conducted in randomly selected 16 townships in Tier I and II areas of MARC zones by quantitative and qualitative approaches. RESULTS: In 832 households resided by 4664 people, there were 3797 bed nets. Around 54% were untreated while 45.6% were insecticide-treated nets (ITN) and 36.2% were long-lasting insecticide-treated nets (LLINs). Proportion of households with at least one ITN was 625 (75.12%), proportion of households with at least one ITN for every two peoples was 487 (58.53%), and proportion of existing ITNs used in previous night was 1225 (70.65%) respectively. Nearly 23% of households had old nets while 52% had new and unused extra bed nets reflecting the adequacy. Interestingly, 38% could not mention the benefit of the use of ITN/LLINs. Although 88.2% knew the disease "malaria", 11.9% could not be able to mention the symptoms. More than 80% provided correct responses that mosquito bite can cause malaria while only 36.9% could mention the blood test for malaria diagnosis. Only 36.6% received malaria information within previous year but nearly 15% could not recognize it. Mostly, 80% of fever episodes were treated at rural health centers (38.24%) followed by drug shops (17.65%) and private clinics (16.18%) respectively. CONCLUSIONS: Efforts should focus on correcting misconceptions about malaria transmission, prevention and universal use of ITN/LLINs. Although BCC activities have been documented, it is still necessary to intensify community mobilization through all accessible multiple channels in MARC areas.

Gastrointestinal parasite infection in small ruminants remains one of the major economic losses caused by reduced productivity. A total of 380 faecal samples were taken from 280 sheeps in Magway and Pwintbyu Townships and 100 goats in Natmauk Township, Myanmar. Faecal flotation and sedimentation methods were carried out to detect the presence of parasitic infections. Faecal egg and oocyst counts were carried out using the McMaster technique. The overall occurrence of gastrointestinal parasites in small ruminants was 98.4% (374/380). The occurrence of gastrointestinal parasites in sheep (99.3%) was higher than that in goats (96%). The highest occurrence was found in Eimeria spp. (96%), followed by Trichostrongyle (77.1%), Trichuris spp. (35%), and Moniezia expansa (14%). The mixed infection rate was 84.8% (317/374), while a single infection was 15.2% (57/374). The mean eggs per gram (EPG) and oocysts per gram (OPG) of faeces were ranged from 50 to 600 and 50 to 29,800, respectively. Among the 4 nucleotide sequences isolated, one sequence was 94.10-94.47% similarity with Trichostrongylus colubriformis, reported from Laos, and three sequences showed 96.64-99.46% identity with Haemonchus contortus from Laos, China, India, and Mongolia. As gastrointestinal parasite infection in small ruminants was relatively high in the study area, the development of appropriate treatment and control measures should be provided to reduce production losses.
RESUMO
Melioidosis is a frequently fatal infectious disease caused by the Gram negative bacillus Burkholderia pseudomallei. Although it was originally discovered in Myanmar, the disease disappeared from sight for many decades. This study focuses on detection of B. pseudomallei in soil in selected sampling sites in an attempt to start to fill the gaps in the current status of our knowledge of the geographical distribution of B. pseudomallei in soil in Myanmar. This cross-sectional study consists of 400 soil samples from 10 selected study townships from two major paddy growing regions. Bacterial isolation was done using a simplified method for the isolation of Burkholderia pseudomallei from soil. In this study, only 1% (4/400) of soil samples were found to be positive; two of four were found at 90 cm depth and another two positive samples were found at 30 cm and 60 cm. This survey has confirmed the presence of environmental B. pseudomallei in Myanmar indicating that the conditions are in place for melioidosis acquisition.
RESUMO
The emergence and spread of drug resistance is a problem hindering malaria elimination in Southeast Asia. In this study, genetic variations in drug resistance markers of Plasmodium falciparum were determined in parasites from asymptomatic populations located in three geographically dispersed townships of Myanmar by PCR and sequencing. Mutations in dihydrofolate reductase (pfdhfr), dihydropteroate synthase (pfdhps), chloroquine resistance transporter (pfcrt), multidrug resistance protein 1 (pfmdr1), multidrug resistance-associated protein 1 (pfmrp1), and Kelch protein 13 (k13) were present in 92.3%, 97.6%, 84.0%, 98.8%, and 68.3% of the parasites, respectively. The pfcrt K76T, pfmdr1 N86Y, pfmdr1 I185K, and pfmrp1 I876V mutations were present in 82.7%, 2.5%, 87.5%, and 59.8% isolates, respectively. The most prevalent haplotypes for pfdhfr, pfdhps, pfcrt and pfmdr1 were 51I/59R/108N/164L, 436A/437G/540E/581A, 74I/75E/76T/220S/271E/326N/356T/371I, and 86N/130E/184Y/185K/1225V, respectively. In addition, 57 isolates had three different point mutations (K191T, F446I, and P574L) and three types of N-terminal insertions (N, NN, NNN) in the k13 gene. In total, 43 distinct haplotypes potentially associated with multidrug resistance were identified. These findings demonstrate a high prevalence of multidrug-resistant P. falciparum in asymptomatic infections from diverse townships in Myanmar, emphasizing the importance of targeting asymptomatic infections to prevent the spread of drug-resistant P.falciparum.

BACKGROUND: The malaria burden of Myanmar still remains high within the Greater Mekong Subregion of Southeast Asia. An important indicator of progress towards malaria elimination is the prevalence of parasite infections in endemic populations. Information about malaria epidemiology is mostly derived from reports of confirmed acute malaria cases through passive case detection, whereas the prevalence of baseline subclinical malaria infections is much less known. METHODS: In this study, cross-sectional surveys were conducted during the rainy season of 2017 in four townships (Bilin, Thabeikkyin, Banmauk and Paletwa) of Myanmar with divergent annual malaria incidences. A total of 1991 volunteers were recruited from local villages and Plasmodium subclinical infections were estimated by light microscopy (LM), rapid diagnostic tests (RDTs) and nested PCR. The nested PCR analysis was performed with a modified pooling strategy that was optimized based on an initial estimate the infection prevalence. RESULTS: The overall malaria infection prevalence based on all methods was 13.9% (277/1991) and it differed drastically among the townships, with Paletwa in the western border having the highest infection rate (22.9%) and Thabeikkyin in central Myanmar having the lowest (3.9%). As expected, nested PCR was the most sensitive and identified 226 (11.4%) individuals with parasite infections. Among the parasite species, Plasmodium vivax was the most prevalent in all locations, while Plasmodium falciparum also accounted for 32% of infections in the western township Paletwa. Two RDTs based on the detection of the hrp2 antigen detected a total of 103 P. falciparum infections, and the ultrasensitive RDT detected 20% more P. falciparum infections than the conventional RDT. In contrast, LM missed the majority of the subclinical infections and only identified 14 Plasmodium infections. CONCLUSIONS: Cross-sectional surveys identified considerable levels of asymptomatic Plasmodium infections in endemic populations of Myanmar with P. vivax becoming the predominant parasite species. Geographical heterogeneity of subclinical infections calls for active surveillance of parasite infections in endemic areas. The pooling scheme designed for nested PCR analysis offers a more practical strategy for large-scale epidemiological studies of parasite prevalence. Such information is important for decision-makers to put forward a more realistic action plan for malaria elimination.

INTRODUCTION: Kyauk Kan village of Nyaung-U, Mandalay region, Myanmar is one of the most famous groundnut-growing zones and has been exposed to pesticides. METHODS: This study design provided evaluation of within-person changes in the season across growing and nongrowing periods. A cross-sectional study was performed to identify health problems related to organophosphate pesticide (OP) exposure, to explore the protected use of this pesticide among 400 participants in the community by face-to-face interviews, and to determine the reproductive effects of OP exposure by using biomarkers of 100 male groundnut farmers aged 18-49 years. RESULTS: The mean age of the participants was 37.5±9.45 years. Analysis revealed statistically significant differences in seminal parameters (P<0.05 for pH, viscosity, motility, morphology, and sperm count) and in a reproductive hormonal assay (P<0.05 in follicle-stimulating hormone and testosterone) between the growing and nongrowing periods. Blood-cholinesterase levels of plasma cholinesterase in the growing period were significantly higher than those in the nongrowing period (P<0.05). CONCLUSION: Our results suggest that chronic exposure related to OP dose may reduce potential male reproductivity.
RESUMO
@#Kimura disease (KD) is a rare benign chronic inflammatory disease that presents as a nodule mostly involving deep subcutaneous tissue of the head and neck region with frequent regional lymphadenopathy and peripheral blood eosinophilia. KD shares some clinical and histopathological similarity with angiolymphoid hyperplasia with eosinophilia (ALHE). Consequently, KD and ALHE were once considered variants of the same disease spectrum. We present here rare cases of Kimura disease and ALHE involving the eyelid and lacrimal gland and discuss their differential features.
RESUMO
BACKGROUND/AIMS: Differences in the Helicobacter pylori infection rate are not sufficient to clarify the dissimilarity of gastric cancer incidence between Myanmar and its neighboring countries. To better understand this trend, the H. pylori virulence gene cagA was characterized in Myanmar. METHODS: Glutamate-proline-isoleucine-tyrosine-alanine (EPIYA) patterns and CagA multimerization (CM) motifs of cagA genotypes were examined by performing polymerase chain reactions and DNA sequencing. RESULTS: Of 69 tested H. pylori strains, cagA-positive patients had significantly more severe histological scores in their antrum than cagA-negative patients. Sequence analysis revealed that 94.1% of strains had Western-type cagA containing an EPIYA motif (92.6%) or EPIYT motif (6.4%). The intestinal metaplasia scores in the antral of patients infected with the ABC and ABCC types of cagA were significantly higher than those of patients with AB-type cagA. Interestingly, in patients infected with H. pylori, 46.3% of strains with three EPIYA motifs contained two identical Western-typical CM motifs, and these patients showed significantly higher antrum inflammation scores than patients infected with two identical nontypical-CM motif strains (p=0.02). CONCLUSIONS: In Myanmarese strains, Western-type cagA was predominant. The presence of CM motifs and the proportion of multiple EPIYA-C segments might partially explain the intermediate gastric cancer risk found in Myanmar.

In common with other low-income countries, diabetes is a growing challenge forMyanmar. Gaps and challenges exist in political commitment, policy development,the health system, treatment-seeking behaviour and the role of traditional medicine.National policies aimed at prevention – such as to promote healthy food, createa healthy environment conducive to increased physical activity, restrict marketingof unhealthy food, and initiate mass awareness-raising programmes – need to bestrengthened. Moreover, existing initiatives for prevention of noncommunicabledisease (NCD) are channelled vertically rather than being horizontally integrated.Primary health care is traditionally orientated more towards prevention of infectiousdiseases and staff often lack training in prevention and control of NCDs. Capacitybuilding activities have been modest to date, and retaining trained health workers indiabetes-oriented activities is a challenge. The World Health Organization Packageof Essential Noncommunicable (PEN) disease interventions for primary healthcare in low-resource settings has been piloted in Yangon Region and countrywide expansion awaits ministerial approval. Recently, the Myanmar Diabetes CareModel was proposed by the Myanmar Diabetes Association, with the aims of bothbridging the gap in diabetes care between rural and urban areas and strengtheningcare at the secondary and tertiary levels. However, implementation will requirepolicy development for essential drugs and equipment, capacity-strengthening ofhealth-care workers, and an appropriate referral and health-information system.

@#Adrenal oncocytomas are rare adrenal neoplasms which are usually large and nonfunctioning. Most of them are benign. We report a rare case of adrenal oncocytoma presenting with bilateral gynaecomastia and hypogonadism in 67-year- old male from Myanmar who had elevated estradiol levels. He successfully underwent an adrenalectomy and the histologic diagnosis was an oncocytoma. The immunohistochemical (IHC) staining was positive for neuron specific enolase (NSE), vimentin and synaptophysin. Feminizing adrenal oncocytoma has not been reported in literature.

A cross-sectional survey combined with 24-hour dietary recall and food diary was undertaken to assess the calcium intake of the Myanmar population. The study was conducted from November 2003 to October 2005. A total of 886 subjects of both sexes aged above 2 years from three States and Divisions (Bago, Kayin, and Yangon) of Myanmar were included in the study. The major measures were mean daily calcium intake (mg/day) and major sources of calcium in the diet. Overall mean calcium intake was 197+13mg/day (2-9 years), 421+2mg/day (10-19 years), 399+21 mg/day (20-49 years), and 383+25mg/day (>50 years) for males, while the corresponding values for females were 207+17 mg/day, 366+19 mg/day, 387+16 mg/day, and 327 +19 mg/day. Calcium intake was less than 80% of the recommended dietary allowances (RDA) for Myanmar for ages 2-9 years and 10-29 years in all the study areas, and for the 50 years and above age group in Yangon. Fish paste was found to be the major source of calcium. Milk and milk products contributed very little to total calcium intake, contributing 2.1% for residents in Yangon, 5.1% in Pa-an and none in Bago. Consumption of calcium rich foods, particularly milk and milk products, should be encouraged among the Myanmar people. Towards this end, appropriate nutrition education materials should be developed for promotional purposes.
RESUMO
@#There has been significant magnitude of problems of diabetes in Myanmar, according to the estimates of International Diabetes Federation (IDF) and the recent National Survey on the prevalence of diabetes. There has been a wide gap of equity between the urban and rural healthcare delivery for diabetes. Myanmar Diabetes Care Model (MMDCM) aims to deliver equitable diabetes care throughout the country, to stem the tide of rising burden of diabetes and also to facilitate to achieve the targets of the Global Action Plan for the Prevention and Control of NCDs (2013-2020). It is aimed to deliver standard of care for diabetes through the health system strengthening at all level. MMDCM was developed based on the available health system, resources and the country's need. Implementation for the model was also discussed.
RESUMO
@#Osteomalacia is one of the post-gastrectomy complications resulting from the impaired absorption of vitamin D and calcium.1 Vitamin D deficiency or osteomalacia can be diagnosed by clinical, biochemical and radiographic parameters, and bone biopsy. The radiologic findings of “Looser zones” or pseudofractures aid in the diagnosis. Severe generalized pain, mimicking rheumatologic disorders is one of the features that maybe a presenting complaint of osteomalacia. We report a case of osteomalacia as a consequence of gastric by-pass surgery.

@#Cardiovascular disease is a significant cause of morbidity and mortality in patients with diabetes mellitus (DM). According to the IDF Diabetes Atlas 2013, the prevalence of diabetes in Myanmar is 5.7%.(1) Diabetes is recognized as a risk equivalent for coronary heart disease. The lipid profile in patients with type 2 DM is characterized by elevated triglycerides, low high-density lipoprotein cholesterol and raised small dense low-density lipoprotein cholesterol (LDL-C) particles. This is believed to be a key factor in promoting atherosclerosis in these patients. There is ample evidence that aggressive statin therapy reduces cardiovascular end points in patients with DM in both primary and secondary prevention studies. In all persons with DM, current treatment guidelines recommend reduction of LDLC to less than 100 mg/dL, regardless of baseline lipid levels. In very high risk patients with DM and coronary heart disease lowering of LDL-C to less than 70 mg/dL may provide even greater benefits. Treatment for hypertriglyceridaemia is recommended only if TG levels is very high (>500 mg/dL).

@#Peripheral artery disease (PAD) broadly encompasses vascular diseases caused primarily by atherosclerosis and thromboembolic pathophysiologic processes that alter the normal structure and function of the aorta, its visceral arterial branches, and the arteries of the lower extremity. The aims of the Myanmar clinical practice guidelines for the management of patients with PAD are to assist physicians in selecting the best management strategies for an individual patient with peripheral artery disease with main focus on lower extremity artery disease (LEAD) due to atherosclerosis, to help the physician to make decisions in their daily practice, and to aid in appropriate referrals to specialists. Early detection and treatment guidelines for the treatment of PAD are important to reduce the morbidity and mortality of patients with vascular problems in Myanmar.
