    Molecular and epidemiologic investigations suggest a causal role for human papillomavirus (HPV) in anogenital cancers. This study identified oncogenic HPV genotypes in anogenital cancers among men and women in a 2013 cross-sectional descriptive study in Myanmar. In total, 100 biopsy tissues of histologically confirmed anogenital cancers collected in 2008-2012 were studied, including 30 penile and 9 anal cancers from Yangon General Hospital and 61 vulvar cancers from Central Women's Hospital, Yangon. HPV-DNA testing and genotyping were performed by polymerase chain reaction-restriction fragment length polymorphism. Overall, 34% of anogenital cancers were HPV-positive. HPV was found in 44.4% of anal (4/9), 36.1% of vulvar (22/61), and 26.7% of penile (8/30) cancers. The most frequent genotypes in anal cancers were HPV 16 (75%) and 18 (25%). In vulvar cancers, HPV 33 was most common (40.9%), followed by 16 (31.8%), 31 (22.7%), and 18 (4.6%). In penile cancers, HPV 16 (62.5%) was most common, followed by 33 (25%) and 18 (12.5%). This is the first report of evidencebased oncogenic HPV genotypes in anogenital cancers among men and women in Myanmar. This research provides valuable information for understanding the burden of HPV-associated cancers of the anus, penis, and vulva and considering the effectiveness of prophylactic HPV vaccination

    Background: Global and regional prevalence estimates for blindness and vision impairment are important for the development of public health policies. We aimed to provide global estimates, trends, and projections of global blindness and vision impairment. Methods: We did a systematic review and meta-analysis of population-based datasets relevant to global vision impairment and blindness that were published between 1980 and 2015. We fitted hierarchical models to estimate the prevalence (by age, country, and sex), in 2015, of mild visual impairment (presenting visual acuity worse than 6/12 to 6/18 inclusive), moderate to severe visual impairment (presenting visual acuity worse than 6/18 to 3/60 inclusive), blindness (presenting visual acuity worse than 3/60), and functional presbyopia (defined as presenting near vision worse than N6 or N8 at 40 cm when best-corrected distance visual acuity was better than 6/12). Findings: Globally, of the 7·33 billion people alive in 2015, an estimated 36·0 million (80% uncertainty interval [UI] 12·9–65·4) were blind (crude prevalence 0·48%; 80% UI 0·17–0·87; 56% female), 216·6 million (80% UI 98·5–359·1) people had moderate to severe visual impairment (2·95%, 80% UI 1·34–4·89; 55% female), and 188·5 million (80% UI 64·5–350·2) had mild visual impairment (2·57%, 80% UI 0·88–4·77; 54% female). Functional presbyopia affected an estimated 1094·7 million (80% UI 581·1–1686·5) people aged 35 years and older, with 666·7 million (80% UI 364·9–997·6) being aged 50 years or older. The estimated number of blind people increased by 17·6%, from 30·6 million (80% UI 9·9–57·3) in 1990 to 36·0 million (80% UI 12·9–65·4) in 2015. This change was attributable to three factors, namely an increase because of population growth (38·4%), population ageing after accounting for population growth (34·6%), and reduction in age-specific prevalence (–36·7%). The number of people with moderate and severe visual impairment also increased, from 159·9 million (80% UI 68·3–270·0) in 1990 to 216·6 million (80% UI 98·5–359·1) in 2015. Interpretation: There is an ongoing reduction in the age-standardised prevalence of blindness and visual impairment, yet the growth and ageing of the world’s population is causing a substantial increase in number of people affected. These observations, plus a very large contribution from uncorrected presbyopia, highlight the need to scale up vision impairment alleviation efforts at all levels

    Background: Contemporary data on causes of vision impairment and blindness form an important basis for recommendations in public health policies. Refreshment of the Global Vision Database with recently published data sources permitted modeling of cause of vision loss data from 1990 to 2015, further disaggregation by cause, and forecasts to 2020. Methods: Published and unpublished population-based data on the causes of vision impairment and blindness from 1980 to 2015 were systematically analysed. A series of regression models were fit to estimate the proportion of moderate and severe vision impairment (MSVI; defined as presenting visual acuity <6/18 but ≥3/60 in the better eye) and blindness (presenting visual acuity <3/60 in the better eye) by cause by age, region, and year. Findings: Among the projected global population with MSVI (216.6 million; 80% uncertainty intervals [UI] 98.5-359.1), in 2015 the leading causes thereof are uncorrected refractive error (116.3 million; UI 49.4-202.1), cataract (52.6 million; UI 18.2-109.6), age-related macular degeneration (AMD; 8.4 million; UI 0.9-29.5), glaucoma (4.0 million; UI 0.6-13.3) and diabetic retinopathy (2.6 million; UI 0.2-9.9). In 2015, the leading global causes of blindness were cataract (12.6 million; UI 3.4-28.7) followed by uncorrected refractive error (7.4 million; UI 2.4-14.8) and glaucoma (2.9 million; UI 0.4-9.9), while by 2020, these numbers affected are anticipated to rise to 13.4 million, 8.0 million and 3.2 million, respectively. Cataract and uncorrected refractive error combined contributed to 55% of blindness and 77% of MSVI in adults aged 50 years and older in 2015. World regions varied markedly in the causes of blindness, with a relatively low prevalence of cataract and a relatively high prevalence of AMD as causes for vision loss in the High-income subregions. Blindness due to cataract and diabetic retinopathy was more common among women, while blindness due to glaucoma and corneal opacity was more common among men, with no gender difference related to AMD. Conclusions: The numbers of people affected by the common causes of vision loss have increased substantially as the population increases and ages. Preventable vision loss due to cataract and refractive error (reversible with surgery and spectacle correction respectively), continue to cause the majority of blindness and MSVI in adults aged 50+ years. A massive scale up of eye care provision to cope with the increasing numbers is needed if one is to address avoidable vision loss

    The main aim of our project work is to determine the calorie content of the five items of Myanmar snacks such as shwe hta min, kauk nyin htoke, mont kywe the, htan thee mont, and mont sein paung from Thanlyin Township. In this research work vitamin B1content was determined by fluorometric method. The highest content of vitamin B1 (0.057mg %) was found in htan thee mont. The protein, carbohydrate, and fat contents were also determined and the highest contents were found in mont sein paung and the values are 4.13g/100g; 39.95g/100g; and l.88g/100g respectively. Mineral contents of the five items of Myanmar snacks were also determined by AAS method. Phosphorous content was the highest in mont sein paung (56.99 mg%); iron content was the highest in htan thee mont (12.17 mg%); sodium, magnesium and potassium contents were the highest in kauk nyin htoke and the values were 10.58 ppm; 4.21 ppm and 7.29 ppm respectively. Calcium content was the highest in mont kywe the (143.08 mg %). The highest energy values of total digestible nutrient were calculated for the given samples and the highest value (187.21 cal/100g) was found in mont sein paung. According to the observation of this work it is clear that among the five items, mont sein paung has the highest calorie content as well as energy value. Not only mont sein paung but also other four items (shwe hta min, kauk nyin htoke, mont kywe the, and htan thee mont) have enough calorie contents to meet human energy requirements

    Since practicing of market oriented economy after 1988, private entrepreneurs have been participating in some formerly state controlled economic activities of Myanmar. Existing small scale economic activities have been also transforming into !be form that is more competitive in market economy. Among them, some kinds of spatial and functional transformation patterns of tea shop are witnessing in Mandalay City. Thus, this paper studies chain lea shops with followings research questions. (1) How do chain tea shops emerge in spatial context of Mandalay City? (2) How do locational and business strategies of chain tea shop differ in urban spatial context? (3) What are the major forces that cause the development of chain tea shops in Mandalay City? To answer above questions, chain tea shops were verified based on Mandalay City Directory 2009 and field surveys. Then, both spatial (location) and attribute (function) data of chain tea shops were collected by field surveys and structured interviews conducted to owners of chain tea shops in 2009. Then, their spatial transformation pattern was analysed by using ArcMap 9.2 software. The results revealed that chain tea shops _ emerged in Mandalay City (1) as a practice of spatial expansion based on !be market strategy of parent tea shop, (2) as a systematic development of family business system, and (3) vertical integration of tea shop related businesses under market oriented economy

    Symptoms, endoscopy, and pH monitoring form the basis of diagnosis of gastroesophageal reflux disease (GERD). Their relationship was meaningful for primary care physicians, but still unclear. This study aimed to determine the relationship among symptoms, mucosa injury, and acid exposure in Gasteroesophageal Reflux Disease. A cross-sectional analytic study was carried out in 48 patients with symptoms of GERD (heartburn or acid regurgitation) after explaining about the study and taking written consent during the one-year period in2015. The patients underwent upper GI endoscopy to assess mucosa injury and 24-hour esophageal pH monitoring to assess pathological acid exposure in Department of Gastroenterology, Yangon General Hospital. The data were then analyzed and their relationships were determined.</p

    BACKGROUND: Dengue fever has seen a significant re-emergence in Southeast Asia. Associated with the rise of dengue has been the increase in dengue-associated mortality. To better understand the predictors of mortality, we conducted a review of hospitalized adult dengue infections within our institution. METHODS: This was a retrospective case-control study of dengue-associated deaths at a large tertiary care hospital. RESULTS: In 2004, of 3186 cases of dengue fever (DF)/hemorrhagic dengue fever (DHF) admitted to our institution, there were 130 cases of DHF and seven dengue-associated deaths (case-fatality rate 5.4%). At least three of the seven fatal cases had serological evidence of primary dengue infection. All dengue-mortality cases had rapidly progressive clinical deterioration at an average of day 4 of fever with intensive care admission occurring on a mean of 5.6 days of fever. Adult respiratory distress syndrome, disseminated intravascular coagulopathy, and multi-organ failure were the most common causes of death despite early hospitalization, intravenous fluid, and blood-product support. CONCLUSION: Dengue is associated with severe disease, and deaths do occur despite current supportive management. Fatal DHF/dengue shock syndrome (DSS) does occur in adults and in primary dengue infection. Better early predictors of disease severity and clinical interventions are needed
