Infection control measures among interns / house surgeons in teaching hospitals under University of Medicine (1), Yangon.

Health care workers are responsible for prevention and control of communicable diseases in the hospital environment. This study aimed to focus on infection control measures among house officers. A cross-sectional descriptive study was conducted in 2010 at three teaching hospitals in Yangon City by introducing anonymous self-administered questionnaires to randomly selected 150 respondents. SPSS version 16.0 was used for analysis. Over half of the respondents had high knowledge and perception but the practice was poor. Infection control messages acquired through health talks, seminars and media were infl uencing factors on knowledge while training programs signifi cantly infl uenced both knowledge and perception. Senior house offi cers had significantly higher mean perception scores than their juniors (p=0.005). Their hand washing practice was signifi cantly infl uenced by newspapers and magazines (p=0.003) and poster and pamphlet(p=0.056). Compliance on utilization of surgical mask as a precautionary measure for airborne transmission was associated with knowledge (0.020), adequate supply in wards (p=0.001) and donation from medical product company (p=0.042). They bought gloves for handling infectious materials (p=0.000), and needle recapping practice before discarding was related to knowledge (p=0.05). Knowledge, perception and practice of house offi cers were interrelated to each other. Further education and training of house surgeons, resource allocation and continuous monitoringwere necessary for proper infection control and safe hospital environment.

Prevalence trend of youth smoking in 29 Townships of Bago, Magwe and Mandalay Divisions, September 1999

In 1999 September a cross-sectional analytic study was conducted in 29 townships of Mandalay. Magwe and Bago divisions of Myanmar. Randomly selected 2074 urban and 1781 rural 15-24 year old youths from 4808 households were interviewed. 5.6 per cent of females and 67.6 per cent of male youths reported as current smokers. At age 14, 37 per cent of the boys smoked. At age 17, more than half of males smoked, and, at age 22 and older, nearly 80 per cent of them were already smoking. Girls started smoking later than boys. Only 1 per cent of 15-year-old girls smoked. When the females reached age 22-24, approximately 10 per cent of them smoked. Comparing different youth cohorts, the younger started smoking earlier than the older youths. Median age of starting tobacco smoking for the 16 year old males was 16; that was approximately 3 years earlier than the median age of smoking for the 24 years old males.

The use of Moringa oleifera (dan-da-lun) seed for the sedimentation and decontamination of household water Part II: Community-based study

The seeds of Moringa oleifera were tested as clearing and sedimentation agents in household water in Thaung Gyi Lay village with 110 households. Questionnaires were completed for each household and follow-up visits were carried out to ascertain the hypothetical acceptability (attitude), initial acceptability (behaviour) and experimental acceptability. It was observed that 78.9 per cent of the people accepted to use Moringa oleifera seeds if these were easily available. For continuous use of Moringa oleifera seeds, 47.3 per cent wanted to use, 44.7 per cent could not decide and only three households (2.7 per cent) did not want to use these. It was observed that the taste and pH of water did not change after treatment with Moringa oleifera seeds. There was no complaint about the treated water. This study will highlight the acceptance to use Moringa oleifera seeds for the sedimentation of turbid water.

The usefulness of Moringa oleifera (dan-da-lun) seed for the sedimentation and decontamination of turbid water from ponds and revers Part I: Laboratory investigations

The seeds of Moringa oleifera were tested as the clearing and sedimentation agents in tubid water from various sources (1) DMR pond (2) Yangon river (3) Bago River (4) Hline River (5) Hlinethaya Pond (6) artesian well from laydaunkkan and (7) Thanlyin River. the turbidity reduction of 80.00 to 99.5 percent paralled by a primary bacterial reduction of 90.00 to 99.99 per cent were obtained within the first one to two hours of treatment, the bacteria being concentrated in the coagulated sediment. It was observed that 100 mg (one ywe) of the seed powder served as a clearing agent in one litre of turbid water. However, the difference of clearing activity was not significant with different amounts of powder, lwhen 50 mg, 100 mg and 200 mg respectively were used with constant water quantity (one litre) within 24 hours. Moreover, the effect of the seeds could not alter the original pH of the tested water samples. The powder of M. oleifera leaves, bark and roots had no power to clear the turbidity of tested water samples.

Serum calcium in normal and preeclamptic pregnant Myanmar women

To study the changes during normal pregnancy and in preeclampsia, serum calcium concentration was measured in 26 apparently healthy pregnant Myanmar women and in 15 preeclamptic patients. They were 20-40 years of age. In healthy pregnant women, serum total calcium levels measured at 24th week, 28th week, 32nd week and 36th week of gestation were 2.45 + or - 0.30 mmol/1, 2.47 + or - 0.29 mmol/1, 2.41 + or - 0.29 mmol/1 and 2.46 + or - 0.29 mmol/1 respectively and ionized calcium levels at these periods were 1.24 + or - 0.15 mmol/1, 1.23 + or - 0.14 mmol/1, and 1.20 + or - 0.16 mmol/1 respectively. In preeclamptic patients, the mean serum total calcium level (2.26 + or - 0.24 mmol/1) was significantly lower than that (2.52 + or - 0.23 mmol/1) of 0.27 mmol/1) and ionized calcium level (1.23 + or - 0.14 mmol/1) of preeclamptic patients were not significantly different from those (2.43 + or - 0.24 mmol/1 and 1.24 + or - 0.13 mmol/1 respectively) of control.

Shigellosis among children attending the paediatric wards of hospitals in suburban areas

A total of 55 cases of children with dysentery admitted to the Defence Services Obstetric, Gynaecology and Children Hospital and North Okkalapa General Hospital were included in this study. It was found that 49.1 per cent of the children were suffering from shigella bacillary dysentery. The Shigella spp. isolated were: Shigella flexneri (44.4 per cent), Shigella dysenteriae (29.6 per cent), Shigella boydii (22.2 per cent) and Shigella sonnei (3.7 per cent). the distribution of Shigella spp. among the different age groups were 42.9 per cent in the age group of less than 6 months, 40 per cent in 6 to 12 months, 55 per cent in 13 to 24 months and 66.7 per cent in 25 to 60 months. Antibiotic susceptibility test revealed that these shigellae were resistant to ampicillin (84 per cent), chloramphenicol (76 per cent), streptomycin (84 per cent), tetracycline (64 per cent) and septrin (72 per cent); were fully sensitive to amikacin, gentamycin, netilmicin, norfloxacin and were less sensitive to cephalothin (76 per cent) and furazolidone (72 per cent).

The association of enteropathogenic Escherichia coli (EPEC) and gastroenteritis

A total of 619 cases of adults with gastroenteritis admitted to Yangon General Hospital, Workers' Hospital and Infectious Diseases Hospital were included in this study. It was observed that 33 percent were suffering from gastroenteritis due to enteropathogenic Escherichia coli (EPEC). The most prominent EPEC sero-groups encoutered were 01, 026, 055, 086, 0114, 0125 and 0128. The antibiotic sensitivity pattern showed that 87 percent of enteropathogenic Escherichia coli (EPEC) were resistant to ampicillin, 58 percent to chloramphenicol, 49 percent to streptomycin, 55 percent to benzyl penicillin, 44 percent and 21 percent respectively to tetracyclline and septrin. They were all sensitive to nalidixic acid but 97 percent to gentamicin, 96 percent to sisomycin and 95 percent to tobramycin respectively.
