thy control were 3.72, mean score of environment domain of patients were 2.73 and healthy control were 3.35. Among patients quality of life showed impaired in low socio-economic condition. Result of this study may help to encourage further research.There is a new public health problem around the world with the emergence and spread of 2019 novel corona virus (2019-nCoV). The disease «coronavirus disease 2019» (COVID-19) was caused by SARS-CoV-2. As virus isolates are unavailable so the public laboratories are now facing a challenge for detecting the virus because there is growing evidence of the outbreak which is more widespread than initially thought. We aimed here to discuss about the current diagnostic methodology for detecting the SARS-CoV-2 in health laboratories. Here we use the Novel Corona virus (2019-nCoV) Nucleic Acid Diagnostic Kit (PCR-Fluorescence Probing) which is a real time reverse transcription polymerase chain reaction (rRT-PCR) test. A total of 230 samples in the department of microbiology, Mymensingh Medical College from 1st, April 2020 were selected for this study. Among them 20(8.69%) were positive for SARS CoV-2 and remaining were negative. Among the positive samples 55% could amplify both the ORF 1ab and N genes. The single gene ORF 1ab or N was positive in 15% and 30% cases respectively. The Ct values ( less then 38) of ORF 1ab gene indicated by FAM dye was 92.8% and N gene curve indicated by ROX dye was 100%. The presence of IC gene curve with Ct values ( less then 38) indicated by CY5 dye among the positives were 70% and 100% in negatives. The Ct values (38-40) of IC (CY5) among the positives were 15%. The present study demonstrates the enormous response capacity of the study kit for detecting SARS-CoV-2 within the laboratories in Bangladesh.The coronavirus disease (COVID-19) is highly pathogenic viral infection caused by SARS-CoV-2. Currently, COVID-19 has caused global health concern. WHO has declared COVID-19 as a pandemic disease on March 11, 2020 and characterized by fever, dry cough, fatigue, myalgia and chest pain with pneumonia in severe cases. The virus has spread to at least 213 countries and more than 9093827 confirmed cases and 471490 deaths have been recorded. In the beginning, the world public health authorities tried to eradicate the disease in China through quarantine but are now transitioning to prevention strategies worldwide to delay its spread. There are some newly developed and promising methods for detection of SARS-CoV-2, in order to facilitate the development of novel approaches for early diagnosis. Nucleic acid based tests currently offer the most sensitive and early detection and confirmation for SARS-CoV-2 infection. Among them Real-time reverse transcription polymerase chain reaction (rRT-PCR) is the most popular and this crisis moment.Rheumatic heart disease is in the declining phase, with the increase of urbanization and increment of availability of healthcare facility. However still it causes a substantial number of morbidity and mortality in South Asia. The prevalence of Rheumatic Fever and Rheumatic heart disease in Bangladesh is still high, 0.6 and 0.3 per thousand populations respectively. In the rheumatic process mitral is the frequently involved valve, mostly in the form of mitral stenosis. Choice of a treatment modality and its success largely depend on the accurate assessment of severity of disease especially the extent and distribution of calcification. Echocardiography has a key role in the determination of the severity of mitral stenosis as well as assessment of details calcification. Conventionally 2 dimensional and Doppler echocardiography is used. Nicotinamide Riboside clinical trial Now a days, 3D echocardiography offers better cardiac imaging for detail evaluation. The heart being a complex structure, the 3D evaluation would certainly offer better imaging foal echocardiography has promising prospects in detecting severity & extent of rheumatic calcification.Type 2 diabetes considered as a compound of metabolic syndrome. It can cause both micro and macrovascular complications. Diabetes is a strong risk factor in the development of atherosclerosis and likewise carotid artery disease. Carotid artery stenosis may cause stroke. Doppler ultrasound is the most common imaging technique for the diagnosis of carotid disease. Objective of the study was to assess the percentage of atherosclerotic carotid disease in asymptomatic Type 2 diabetics (T2D) by Doppler sonography and to find out the association of different risk factors of diabetic patient with atherosclerosis. A cross sectional study was done. A total of 43 type 2 diabetic patients (27 male, 16 female) referred from the out patient department and admitted patients in Mymensingh Medical College Hospital (MMCH) during January 2017 to December 2017 for the purpose of evaluation of intima media thickness (IMT) and carotid artery stenosis by Duplex color Doppler ultrasonography examination were enrolled in this study. Patients with previous history of recent stroke or transient ischemic attack (10 years, hypertension, history of ischaemic heart disease and history of diabetic retinopathy were found to be associated with carotid atherosclerosis as well as carotid stenosis. High percentage of carotid artery disease (65.1%) was found in asymptomatic type 2 diabetes mellitus. This result suggests the need for carotid Doppler evaluation of all Type 2 diabetics as a first measure of stroke prevention, with the hope that timely intervention might avert stroke and its accompanying disability.Acute appendicitis is the commonest cause of acute abdomen necessitating surgical intervention and wound infection is the most frequently encountered complication following appendicectomy. To assess the effectiveness of pressurized normal saline irrigation of subcutaneous tissue following appendicectomy in decreasing wound infection this quasi experimental study was done in Surgery Unit III, Mymensingh Medical College Hospital from January 2018 to December 2018. In this study total 200 patients of acute appendicitis were enrolled according to inclusion and exclusion criteria and assigned equally into two groups by non-equivalent control group design. In control group all the standard protocol of wound closure following appendicectomy was followed and in experimental group along with the standard protocol the subcutaneous tissue was irrigated by pressure with normal saline and all the data were recorded in individual case record form. Among the sample most of the patients were between 10-19 years of ages and the male female ratio was 1.
