| 2 | Burden and outcome of human influenza in a tertiary care hospital of Bangladesh显示文摘Objective:To determine the magnitude and outcome of influenza in southern part of Bangladesh and also to identify intrusion of novel influenza virus.Methods:This study was conducted for two years(2008-2009) in outpatient and inpatient department of both paediatrics and medicine discipline of Khulna Medical College Hospital.Nasal and throat swab specimens were collected from each influenza like illness(ILI) case and kept together in a virus transport media and transported to international centre for diarrhoeal disease and research,Bangladesh laboratory. Influenza virus was detected by rRT-PCR including types and subtypes.Results:A total of 526 patients were enrolled during the study period with the mean(SD) age of 19(17) years. Identification of influenza virus was 14%and positive cases were mostly found in under-five children(24%).The vast majority(88%) of influenza cases were found during April to September. Virus detection rate was higher in inpatient department(IPD)(21%) than in outpatient department (12%).The dominant virus type and subtype was influenza A(87%) and H3(49%),respectively. Type A was significantly higher than type B in causing severe illness compared to ILI(0R=7.04, 95%CI:2.76-18.7,P<0.01).Headache and chest indrawing was found in significantly higher proportion(P<0.05) in influenza positive IPD cases.Among 31 hospitalized cases majority(77%) recovered completely except two cases that needed referral for additional support.Conclusions: Influenza mostly affected under-five children and young adult.The peak season here was late summer and rainy season. | Rasul CH Bakar MA Mamun AA Siraz MS Zaman RU | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，6： | 1 |
| 4 | Study of whole-body occupational radiation exposure in the industrial radiography in Bangladesh显示文摘Objective:In order to understand the complete scenario of the effectiveness of radiation protection practice in the workplace,especially in the industrial radiography and also to analyze the trends with other related studies,epidemiological studies and legal purposes,the assessment and register of the effective dose plays a significant role.Therefore,efforts have been given in the assessment of collective effective dose,mean effective dose,prediction of lifetime cancer risk,and contribution of different age group workers in the collective effective dose.Methods:The occupational radiation exposures for 472 workers were investigated in industrial radiography throughout Bangladesh from 2015 to 2018 by using thermoluminescent dosimeter(TLD).By using a Harshaw TLD reader(Model-4500),the effective dose was measured in a quarterly basis throughout the year.Based on the value of personal dose equivalent Hp(10),database was prepared and recorded.Results:The collective effective dose was 36.1,40.7,28.8 and 37.5 man⋅mSv among 105,102,100 and 165 radiation workers in 2015,2016,2017 and 2018,respectively.The maximum effective dose received by radiation workers was 6.0,7.1,6.9 and 19.9 mSv in 2015,2016,2017 and 2018,respectively,which remained within the stipulated dose limits imposed by Nuclear Safety and Radiation Control(NSRC)Rules-1997,Bangladesh and International Commission on Radiological Protection(ICRP-103).Conclusion:This kind of monitoring would help to construct a national database that will be used by the end users to improve their implementation of optimization in occupational radiation protection in industrial radiography. | Selina Yeasmin Subrata Banik MMMahfuz Siraz Shikha Pervin Mayeen Uddin Khandaker Mohammad Sohelur Rahman | 2021 | Radiation Medicine and Protection2021，2，3： | 0 |
