Studies on the bionomics of Anopheles dirus (Culicidae: Diptera) in Mudon, Mon State, Myanmar.

This study examined some environmental factors influencing the larval habitats of Anopheles dirus (breeding in wells) in Mudon, Myanmar, from May 1998 to March 2000. The larval/pupal density was found to be directly proportional to rainfall and indirectly proportional to the well water level. Shade, vegetation and debris on the surface of well water were important factors influencing the abundance of the aquatic stages of An. dirus. Salinity had an inverse correlation with the larval and pupal density. Other mosquito species associated with An. dirus were identified. Important predators of the mosquito larvae were larvivorous fish, damselfly and dragonfly nymphs. All wells examined were lined with lateritic rocks. Chemical analysis of water samples from wells was conducted.

Recent levels and trends of fertility and mortality in Myanmar.

"Because the Government of Myanmar (formerly known as Burma) considers the country under-populated, it has not adopted a family planning programme. However, recent data show that, while fertility remains high, there has been some decline since the mid-1970s. Since the mid-1950s, mortality has gradually declined, but the decline seems to have slowed down in recent years. This article concludes that it is necessary to slow population growth by controlling fertility in order to achieve economic and social development."

An epidemiologic study of 70 oral cancer cases at the Institute of Dental Medicine, Yangon, Myanmar, 1985-1988.

This study shows that in Myanmar, South-East Asia, the prevalence of oral cancers is a serious fact as they rank fifth among all cancers being known there. On the 70 oral cancer cases reported at the Institute of Dental Medicine, Yangon, the findings stressed that most patients, male or female, came from the metropolitan division (Yangon), had smoking and chewing habits. Also most of these patients came to hospital only at the severe and late stage. It confirms us in our opinion that early diagnosis and prompt treatment are a necessity.

Thalassemia in the outpatient department of the Yangon Children's Hospital in Myanmar: cost analysis of the day-care-room services for thalassemia.

A cost analysis study for the fiscal year 1989-1990 was conducted in the day care room (DCR) for thalassemia patients at the Yangon Children's Hospital in Myanmar to provide a basis for future cost-effectiveness, cost-benefit and efficiency analyses. Two types of costs, hospital costs and costs borne by the patients' families were studied by reviewing hospital records and by interviewing family members of patients. Of the total cost of DCR services for thalassemia 74 to 75% was contributed by material costs most of which were for imported items. The cost of each transfusion visit and the annual cost per patient were Kyats 166.5 to 173.3 and Kyats 1,108.6 to 1,208.7, respectively. The median cost (range) per treatment visit and the averaged annual median cost (range) borne by the patients' families were Kyats 21 (0-302) and Kyats 107 (0-1,509), respectively.

Pneumocystis carinii infection among human immunodeficiency virus (HIV) infected Myanmar patients.

A total of 60 HIV infected patients complaining of dry cough for at least two weeks and attending the Out-patient Department of the Specialist Hospital, Waibargi, were screened for Pneumocystis carinii. Induced sputum samples were examined with Giemsa and Gomori silver methenamine stains. P. carinii were detected in 18 patients (30%) with silver stain and 13 patients (21.7%) with Giemsa stain. The sensitivity and specificity of the Giemsa stain were 72.2% and 95.2%, respectively. The range of CD4 counts in P. carinii-positive patients was found to be 0-562/microl, and the mean CD4 count was 132.3/microl. Out of 18 P. carinii-positive cases, CD4 counts of 15 cases (83.3%) were <200/microl and those of 3 cases were >200/microl. Clinically, P. carinii-positive cases were associated with fever in 55.5%, with tightness of the chest in 38.9%, and with cyanosis and tightness of the chest in 11.1%. Co-infection with tuberculosis was found in 16.7%. Anti-pneumocystic prophylaxis is recommended for those patients with a CD4 count <200/microl. Giemsa staining could be used as an alternative diagnostic method for detecting P. carinii. This study documented the existing prevalence of P. carinii among HIV-infected Myanmar patients.

Knowledge, attitudes and practices with regard to malaria control in an endemic rural area of Myanmar.

Malaria is a global health problem, in particular, a major health problem within Southeast Asia. This study aimed to investigate malaria control within a rural area of Myanmar, where traditionally non-western medicine is the preferred treatment. Whilst malaria was perceived by the local people to be a major health problem, knowledge about the mode of transmission and correct treatment for malaria was relatively low. Consequently, the practices of the local people to control malaria were often ill-informed or based on cultural and traditional beliefs.

A study of'febrile illnesses on the Thai-Myanmar border: predictive factors of rickettsioses.

We have performed a case-control analysis to determine the significance of clinical, laboratory and epidemiological features as predictive factors of rickettsioses among patients in Sangkhla Buri, Thailand (Thai-Myanmar border). Fifteen serologically-confirmed rickettsiosis patients including Spotted Fever Group (SFG) rickettsioses, scrub typhus, and murine typhus were classified as 'cases'; one hundred and sixty-three acutely febrile patients presenting to the same hospital during the same time period, who had no serological evidence of acute rickettsiosis, were classified as 'controls'. Patients' report of rash/arthropod bite [Odds ratio (OR) 22.90, 95% CI (confidence interval) 6.23, 84.13] and history of jungle trips (OR 5.30, 95% CI 1.69-16.62) were significant risk factors. Elevated ALT (OR 3.04, 95% CI 1.04, 8.88) and depressed platelet count (OR 3.38, 95% CI 1.13, 10.10) were also useful differentiating markers of rickettsioses in this population. Definitive diagnosis of rickettsioses is difficult without specialized diagnostic capabilities that are rarely available in remote areas such as Sangkhla Buri, where other acute febrile illnesses with similar presentation are commonly found. The relative importance of predictive factors presented here may provide clinicians with some useful guidance in distinguishing rickettsioses from other acute febrile illnesses. Timely administration of empiric treatment in highly suspicious cases can deter potential morbidity from these arthropod-borne infections.

pfmdr1 genotyping and in vivo mefloquine resistance on the Thai-Myanmar border.

Molecular markers have been proposed as a method of monitoring malaria drug resistance and could potentially be used to prolong the life span of antimalarial drugs. Single nucleotide polymorphisms (SNPs) in the Plasmodium falciparum gene pfmdr1 and increased gene copy number have been associated with in vitro drug resistance but have not been well studied in vivo. In a prospective cohort study of malaria patients receiving mefloquine treatment on the Thai-Myanmar border, there was no significant association between either pfmdr1 SNPs or in vitro drug sensitivity and mefloquine resistance in vivo. Increased pfmdr1 gene copy number was significantly associated with recrudescence (relative risk 2.30, 95% CI 1.27-4.15). pfmdr1 gene copy number may be a useful surveillance tool for mefloquine-resistant falciparum malaria in Thailand.

Household income, health and education in a rural area of Myanmar.

This study was to determine the relationship between a commonly used social stratification indicator, net equivalent income, and self-rated health, long-term disability, visual acuity status, death rate, birth rate, unsafe delivery and school enrollment in a rural area of Myanmar. Data were collected from 3,558 respondents in 805 households of all ages. Data analysis for various items was based on different age groups. The results from two income groups (highest and lowest) are as follows: the percent of those who self-rated their health as very good were 17.8% and 10.4% in the highest and lowest income groups, respectively (adjusted coefficient = 0.30, 95% Cl 0.11-0.50); those with an acute medical condition were found in 16.3% and 20.8% in the highest and lowest income groups, respectively (adjusted OR = 1.35, 95% Cl 1.08-1.68); those with long-term disability were found in 15.3% and 21.2% in the highest and lowest income groups, respectively (adjusted OR = 1.39, 95% Cl 1.05-1.84); and those with poor visual acuity at a distance of 13 feet were found in 8.1% and 13.5% in the highest and lowest income groups, respectively (adjusted OR = 1.64, 95% Cl 1.18-2.30). The birth rate ratio was 1.3, the death rate ratio was 1.2, and school enrollment was found in 92.8% and 83.2% in the highest and lowest income groups, respectively (adjusted OR = 0.34, 95% Cl 0.1-0.8). These results indicate that there is an urgent need to strengthen the health care infrastructure and educational system, targeting the poor in rural areas.

Causes of fever in adults on the Thai-Myanmar border.

A hospital-based study was conducted along the Thai-Myanmar border to provide greater knowledge of the causes of febrile illness and to determine what zoonotic and vector-borne emerging infectious diseases might be present. A total of 613 adults were enrolled from June 1999 to March 2002. Cases were classified based on clinical findings and laboratory results. An etiologic diagnosis was made for 48% of subjects. Malaria was the most common diagnosis, accounting for 25% of subjects, with two-thirds Plasmodium falciparum. Serologic evidence for leptospirosis was found in 17% of subjects. Other etiologic diagnoses included rickettsial infections, dengue fever, and typhoid. The most frequent clinical diagnoses were nonspecific febrile illness, respiratory infections, and gastroenteritis. Clinical associations were generally not predictive of etiologic diagnosis. Apparent dual diagnoses were common, particularly for malaria and leptospirosis. Findings have been used to modify treatment of unspecified febrile illness in the area.

In vitro susceptibility and genetic variations for chloroquine and mefloquine in Plasmodium falciparum isolates from Thai-Myanmar border.

In vitro drug susceptibility to chloroquine (CQ) and mefloquine (MF) were assessed in 39 P. falciparum isolates from the Thai-Myanmar border area. To further characterize CQ- and MF-resistance profiles in this area, we also analyzed pfcrt K76T mutation that is critical for CQ resistance, and pfmdr1 polymorphism that has an association with MF resistance. Eighteen isolates were successfully examined by in vitro tests for CQ, and 17 of them had resistance to the drug. Geometric mean concentration of CQ that inhibited the growth of parasites at 50% (IC50) was 371 +/- 227 nM (105-971 nM). Sixteen isolates were successfully examined by in vitro tests for MF, and 8 of them were resistant to the drug. Geometric mean of IC50 for MF was 41 +/- 31 nM (4-125 nM). Genotypes of drug resistance, such as pfcrt and pfmdr1 mutations, were also analyzed. All the 39 isolates had the same haplotype (CVIET) for PfCRT at its 72-76th amino acids. A pfmdr1 Y86 mutation was found in 95% of isolates. A pfmdr1 D1042 mutation was also present in 7 isolates, while no pfmdr1 Y1246 mutation was observed. These results indicated a correlation between CQ resistance and the pfcrt T76 and pfmdr1 Y86 mutations.

Culex quinquefasciatus in Phitsanulok as a possible vector of nocturnally periodic Wuchereria bancrofti transmission in Myanmar immigrants.

The present study was undertaken in order to study whether Culex quinquefasciatus collected in Phitsanulok Province can be an insect host for the development of Wuchereria bancrofti larvae. W. bancrofti infected blood from Myanmar workers in Mae Sot, Tak Province was fed to mosquitoes by using the artificial membrane feeding. An infection of W. bancrofti was found with the highest density of L3 in the mosquito thorax on the 14th day after feeding. The infection rate also correlated to the density of microfilaria found in the donor's blood. Our results showed that Cx. quinquefasciatus in Phitsanulok is a possible vector of nocturnally periodic W. bancrofti.

Private GPs contribute to TB control in Myanmar: evaluation of a PPM initiative in Mandalay Division.

SETTING: Mandalay Division, Myanmar. AIM: To assess the effect of an initiative to involve private general practitioners (GPs) in the National Tuberculosis Programme (NTP) and to identify lessons learnt for public-private mix scale-up. METHODS: Source of referral/diagnosis and place of treatment were included in the routine recording and reporting systems to enable disaggregated analysis of the contribution of GPs to case notification and treatment outcomes. Case notification trends were compared between the intervention and control areas over a 4-year period. RESULTS: Private GPs contributed 44% of new smear-positive cases registered during the study period (July 2002-December 2004). The notification of new sputum smear-positive TB in the study area increased by 85% between the year prior to the GP involvement and 2 years after (from 46 to 85/100,000). Case notification increased by 57% in the control townships and by 42% in all of Mandalay Division. The treatment success rate for new smear-positive cases treated by GPs was 90%. CONCLUSIONS: The involvement of private GPs substantially increased TB case notification, while a high treatment success rate was maintained. Success factors include a well-developed local medical association branch, strong managerial support, training and supervision by the public sector and provision of drugs and consumables free of charge by the NTP.

Ascaris cholecystitis and cholangitis: an experience in Myanmar.

Twenty-seven cases of ascaris cholecystitis and cholangitis were managed in a surgical unit of a general hospital in Yangon, Myanmar, from January 1989 to March 1990. Nineteen women and eight men with a mean age of 42 years were studied. Main clinical manifestations were right hypochondrial pain, fever, chills, rigors, nausea, vomiting and jaundice. Diagnosis was established by abdominal ultrasonograms in all cases. Laparotomy was performed in all cases because of failure to respond to initial conservative treatment. Live and dead ascarids were found in the gall bladder and biliary ductal system. Cholecystectomy, bile duct exploration, worm extraction and T-tube drainage were done in all cases. There were no deaths. Two patients developed minor wound sepsis. During the follow-up period ranging from 3 to 12 months, there was no recurrence of symptoms in all patients. All patients were given antihelminthics before discharge and three weeks later.

Maternal and newborn thyroid hormonal profile in a non-goitrous area of Myanmar.

Serum thyroxine (T4), triiodothyronine (T3) and thyrotropin (TSH) levels of 325 pairs of blood samples from the newborn infants and their mothers were determined with the aim of establishing the thyroid hormonal profile of the newborn babies and their mothers in a non-goitrous area of Myanmar. The mean +/- SEM cord serum T4, T3 and TSH levels were 117.47 +/- 1.92 nmol/l, 0.57 +/- 0.02 nmol/l and 6.41 +/- 0.84 mu/ml respectively. The corresponding maternal levels were 146.29 +/- 2.06 nmol/l, 2.33 +/- 0.04 nmol/l and 2.59 +/- 0.17 mu/ml maternal serum T4 and T3 levels were significantly higher than the corresponding cord serum values (p < 0.0001 in both cases) and maternal TSH level was significantly lower than cord level (p < 0.0001). Maternal and cord T4, T3 and TSH levels of premature infants were not significantly different from those of mature infants. Similarly maternal and cord hormonal levels of male infants were not significantly different from those of female infants.

Vibrio spp. isolated from natural waters of the city of Yangon, Myanmar.

Virulence properties of the environmental isolate of vibrios from natural waters of Yangon, Myanmar were studied. Vibrio spp. were isolated for identification by the membrane filtration method and cultured on thio-sulphate-bile-sucrose media. No Vibrio cholerae O1 were isolated. V. cholerae non-O1 were the major vibrio species isolated from the samples. None of them were detected for cholera-toxin-like toxin, thermostable direct haemolysin, or heat-stable enterotoxin. Sixty-one isolates gave haemolytic activity; 27 V. cholerae non-O1 and 6 V. fluvialis isolates produced protease.
