Abstract
Eosinophilic esophagitis (EoE) is a disease of modern era. It was first described 40 years back. Since then it has drawn an immense interest among the clinicians. It is diagnosed by the presence of eosinophils count ≥15/HPF on esophageal biopsied mucosa in patients with symptoms of esopohageal dysfunction. It is more prevalent among patients with gastroesophageal reflux disease. As its symptoms overlap with that of gastroesophageal reflux disease (GERD), it is frequently overlooked & misdiagnosed which increases patients' sufferings. No data is available in Bangladesh. The objective of the study was to find out the frequency of eosinophilic esophagitis among patients with gastroesophageal reflux symptoms. The study was conducted at the Outpatient department of the department of Gastroenterology of Dhaka Medical College Hospital, Dhaka, Bangladesh from September 2018 to April 2019. One hundred and thirty three (133) consecutive patients with symptoms suggestive of gastroesophageal reflux disease based on validated questionnaire underwent upper GI endoscopy. Biopsies were taken from proximal and distal esophagus as well as any other endoscopically abnormal esophageal mucosal lesion. Among 133 patients with gastroesophageal reflux symptoms, 7 patients (5.3%) were found to be positive for eosinophilic esophagitis. Mean age at diagnosis was 37.28±13.38 years. It was more common in younger age group. Female patients (56%) were more than male patients (44%). Heart burn was the major symptom followed by acid regurgitation. Nocturnal cough showed statistically significant relationship with eosinophilic esophagitis. Although the frequency is low, it may be considered as a differential diagnosis among patients with GERD.

Abstract
Among the various types of decorative materials used in Bangladeshi dwellings, the marble/marble stone is one of the most common ones that used largely for enhancing the beauty and/or aristocracy of the dwelling environment. In this study, the most commonly used, six types of marble stones, have been analyzed for retrospective accident dosimetry. With the interest of characterizing several key thermoluminescence properties to examine their potentiality for dosimetry, annealing - irradiation - readout steps have been done chronologically which comprises the analysis of glow curves, relative sensitivity, dose dependence, repeatability and fading. Considering the various TL parameters, marble 'Carrara' imported from Italy present relatively better capability for reconstruction of radiation dose in the dose range of 10-50 Gy. From fading result, it is clear that for reconstruction of absorbed dose up to four weeks of post exposure, the marble 'Carrara' is found to be the most reliable media among the studied marble types. The Zeff values for the various marble samples are found to be in the range of 13.65-19.12, comparing favorably in replace of TLD-200 (Zeff = 16.3) which can be used for low-level environmental radiation dosimetry. Present work constitutes the first study to investigate the potentials of marble stone for reconstruction of absorbed dose in the range of 10-50 Gy dose.

Abstract
Recent achievements, based on lead (Pb) halide perovskites, have prompted comprehensive research on low-cost photovoltaics, in order to avoid the major challenges that arise in this respect: Stability and toxicity. In this study, device modelling of lead (Pb)-free perovskite solar cells has been carried out considering methyl ammonium tin bromide (CH3NH3SnBr3) as perovskite absorber layer. The perovskite structure has been justified theoretically by Goldschmidt tolerance factor and the octahedral factor. Numerical modelling tools were used to investigate the effects of amphoteric defect and interface defect states on the photovoltaic parameters of CH3NH3SnBr3-based perovskite solar cell. The study identifies the density of defect tolerance in the absorber layer, and that both the interfaces are 1015 cm-3, and 1014 cm-3, respectively. Furthermore, the simulation evaluates the influences of metal work function, uniform donor density in the electron transport layer and the impact of series resistance on the photovoltaic parameters of proposed n-TiO2/i-CH3NH3SnBr3/p-NiO solar cell. Considering all the optimization parameters, CH3NH3SnBr3-based perovskite solar cell exhibits the highest efficiency of 21.66% with the Voc of 0.80 V, Jsc of 31.88 mA/cm2 and Fill Factor of 84.89%. These results divulge the development of environmentally friendly methyl ammonium tin bromide perovskite solar cell.

Abstract
Cellular death of bone due to impairment of the blood supply leading to collapse resulting in pain, and loss of joint function is known as avascular necrosis (AVN). The head of femur is the most common bone affected by avascular necrosis followed by talus and scaphoid. We evaluate the results of core decompression with non-vascularized fibular graft in avascular necrosis of femoral head. This quasi experimental study was done at Mymensingh Medical College Hospital, Dhaka Medical College Hospital and some other private hospitals of Bangladesh. The study includes patients who underwent core decompression and non-vascularized fibular grafting in avascular necrosis of femoral head from January 2017 to December 2018. In this study we evaluated total 20 patients and majority of the patients belongs to the group of 20-30 years. Out of 20 patients, 8 of them were unilaterally involved rest 12 had bilateral involvement. Out of 24 hips of bilateral involvement 4 were grade III and IV (Ficat and Arlet classification) therefore not included in the study. So, we study 28 hips only. The average success rate was 90% after core decompression and non-vascularized fibular bone grafting. Harris hip score of 60 on presentation had poorer outcome. Patients with less than 80 degrees of flexion had poorer outcome.

Abstract
The cross sectional descriptive type of observational study was aimed to evaluate the association of serum free testosterone in 59 patients of carotid atherosclerotic male {<50% stenosis (n=26); >50% stenosis (n=33) } from March 2015 to February 2016 in the Department of Radiology & Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU) & National Institute of Neurosciences (NINS), Dhaka, Bangladesh. Twenty seven patients who had normal carotid doppler findings were taken as control. Serum total testosterone and sex hormone binding globulin was measured by chemiluminescence micro particle immunoassay and free testosterone was done by using Vermeulen formula. Concentration of free testosterone differed significantly among groups (p=0.004) and it was significantly lower in <50% stenosed group. Logistic regression analysis revealed that low free testosterone (free testosterone ≤0.24 nmol/L) was independently associated with development of carotid atherosclerosis (p=0.04, OR 3.07, 95% CI 1.14-9.30). In conclusion low serum free testosterone was associated with carotid atherosclerosis in male.

Abstract
Low back pain (LBP) is a common problem and is an important public health issue. A major proportion of LBP is concomitant with prolong and repetitive awkward postures, related with occupation like miners, health workers and professional drivers. Physicians are exposed to a wide range of occupational risk factors which results in LBP. A variety of occupational and personal factors are responsible for increased risk of low back pain among physicians. This cross sectional descriptive study was carried out at Mymensingh Medical College Hospital during the period of January 2018 to June 2018, to estimate the proportion of LBP among physicians. Data were collected from purposively selected 102 physicians of different levels by face to face interview using a case record form. Informed written consent of participants was taken prior to interview. Data were analyzed by using SPSS version 20.0. The study results revealed that majority (60.8%) of the physicians were in the age group of 31-50 years. Mean age of the physicians was 49.9 years with a standard deviation (SD) of 3.61 years. More than three fourth (79, 77.5%) of the physicians were male and 23(22.5%) were female. Out of 102 physicians more than two third (70, 68.6%) had LBP while 32(31.4%) did not have any LBP. Proportion of low back pain among physician was 68.6%. Low back pain was found in all age group. Among the physicians having low back pain, 55(78.6%) were male and 15(21.4%) were female. Among 102 physicians, 45(44.1%) had different types of comorbidities while 57(55.9%) did not have any comorbidities. Among the co-morbidities HTN, DM, Dyslipidemia, CHD and asthma were common. Results of the study concluded that 68.6% physicians had low back pain. Physicians of age group 31-60 years (88.5%) and male (78.6%) experienced LBP more. Further multi-centric large scale case control study is recommended to determine the risk factors of LBP among physicians of Bangladesh.

Abstract
In the current study, the Asinex and ChEBI databases were virtually screened for the identification of potential Lyn protein inhibitors. Therefore, a multi-steps molecular docking study was carried out using the VSW utility tool embedded in Maestro user interface of the Schrödinger suite. On initial screening, molecules having a higher XP-docking score and binding free energy compared to Staurosporin were considered for further assessment. Based on in silico pharmacokinetic analysis and a common-feature pharmacophore mapping model developed from the Staurosporin, four molecules were proposed as promising Lyn inhibitors. The binding interactions of all proposed Lyn inhibitors revealed strong ligand efficiency in terms of energy score obtained in molecular modelling analyses. Furthermore, the dynamic behaviour of each molecule in association with the Lyn protein-bound state was assessed through an all-atoms molecular dynamics (MD) simulation study. MD simulation analyses were confirmed with notable intermolecular interactions and consistent stability for the Lyn protein-ligand complexes throughout the simulation. High negative binding free energy of identified four compounds calculated through MM-PBSA approach demonstrated a strong binding affinity towards the Lyn protein. Hence, the proposed compounds might be taken forward as potential next-generation Lyn kinase inhibitors for managing numerous Lyn associated diseases or health complications after experimental validation.

Abstract
Standard mitral valve replacement in patients with chronic mitral valve regurgitation and mitral valve stenosis consistently results in a decrease in early postoperative left ventricular ejection performance. Some studies showed that preservation of mitral valve leaflet and subvalvular apparatus can reduce postoperative left ventricular dysfunction. On the basis of the concept, this randomized clinical trial comparing mitral valve replacement with preservation of mitral subvalvular apparatus and conventional mitral valve replacement performed in National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh, in the period of July 2010 to December 2011. We included 60 patients of mitral regurgitation and mitral stenosis, among them 30 patients underwent mitral valve replacement with preservation of mitral subvalvular apparatus (Group A) and 30 patients underwent conventional mitral valve replacement (Group B). There was no significant difference between two groups in terms of peri-operative variables. But there was significant higher incidence of Low cardiac output (LOS) syndrome [36.7% vs. 6.9% (p<0.05)] and congestive heart failure in Group B than Group A. The duration of ICU stay was also significantly higher in conventional mitral valve replacement group [113.23±11.30 hours vs. 96.23±20.02 (p=0.001)]. Additionally, there was significantly less fall of left ventricular ejection fraction in preservation of mitral subvalvular apparatus group [preop 65.27±5.45, at discharge 54.31±3.78, after 3 months 58.28±5.20 (p<0.0001)] than conventional group [preop 66.43±4.58, at discharge 46.43±3.87, after 3 months 46.55±3.63 (p<0.0001)]. In this study left ventricular ejection fraction was used as measure of left ventricular function. We postulate that, this relative preservation of left ventricular ejection fraction was likely the result of preservation of mitral subvalvular apparatus.

Abstract
The timing of eating, relative to when feed is offered, is affected by the social rank of feedlot cattle due to limited feed bunk space. As cattle can select feed based on dietary preference, the timing of eating for cattle in feedlot may be associated with the ingested diet composition. Our objectives were to determine the nutritive value and timing of feed ingested by 100 feedlot cattle during transition and the association of timing of eating with feeding behaviours and average daily gain (ADG). Cattle behaviour and timing of eating were determined on 100 feedlot cattle using accelerometer-based ear tag sensors from days 3 to 6 post feedlot induction (observation period), and the ongoing impact of this period on ADG was determined for the full feed period (75 days). To determine eating patterns at the time of feed offer, cattle were grouped according to the number of days they were recorded as eating within 1 h of feed being offered across 4 observation days, G0: not present across 4 days, G1: present for 1 day, G2: 2 days, G3: 3 days and G4: present for each of the 4 days. Total mixed ration (TMR) samples were collected for nutritive value analysis from four locations along the feed bunk from the time feed was offered and at hourly intervals thereafter for 7 h each day during the observation period. The composition of feed in the bunk changed across the 7 h of measurement (P < 0.05). The DM and CP of feed increased from 65 to 70% and 15 to 16%, respectively, and the NDF decreased from 36 to 32%. Thus, the preferred TMR feed component was the fibrous dietary fraction. However, the overall composition of the ingested diet for 7 h post feeding was similar between groups. Cattle in G0 had reduced eating time (0.7 vs 4.8%; P < 0.001), rumination time (4.5 vs 19.5%; P < 0.001) and ADG (1.0 vs 1.3 kg/d; P < 0.05) across the study, as compared with cattle in G4. Offering a more fibrous ration during feedlot transition, and customised cattle segregation and/or customised feeding regimes based on sensor derived feeding behaviour profiles during acclimation to feedlot can optimise ADG, animal welfare and feedlot profit.

Abstract
This study evaluates essential and toxic element contents in dragon (Hylocereus undatus (Haworth) Britton and Rose) and pomegranate (Punica granatum L.) and possible health risks through the consumption of these fruits. Total concentrations of 15 chemical elements (Al, Br, Ca, Cd, Cl, Cr, Cu, Fe, Hg, K, Mn, Na, Ni, Pb, and Zn) were determined by instrumental neutron activation analysis (INAA) and atomic absorption spectrometry (AAS) techniques. This study indicates that these fruits are a vital source of essential elements for human health. It is observed that Pb concentrations were higher in both fruits whereas Cd concentrations were slightly higher than WHO/FAO tolerable levels only in pomegranate. The estimated daily intake (EDI) of the chemical elements was within the maximum tolerable daily intake (MTDI) values. Furthermore, target hazard quotient (THQ) values were also within the safe level (THQ < 1). However, the calculated target carcinogenic risk (TCR) values of Cd for pomegranate and Cr for dragon fruit were higher than the maximum limit (1.0 × 10-4) for children. Finally, this study will create public awareness about micronutrient contents as well as metal contaminations of the studied fruits.

Abstract
INTRODUCTION Currently, there are several attempts to find an effective antiviral drugs against the COVID-19. Although majority of the COVID-19 patients have mild to moderate clinical events, up to 5-10% may have severe, life threatening events that urgently require effective drugs. The purpose of this systematic review is to evaluate the effectiveness of antiviral therapies in the treatment of COVID-19. METHODS An extensive search was performed in PubMed, EMBASE, Cochrane Library for randomised controlled trials (RCTs), prospective case series studies that evaluated therapies COVID-19. The outcomes searched for were mortality, recovery rate, length of hospital stay and clinical improvement from January to May 15, 2020. Independent reviewers searched, identified, screened, and related studies were included. RESULTS Total of five RCTs on 439 patients and seventeen case series involving 1656 patients were found in the specified review period that reported the use of Lopinavir, Ritonavir, Remdesivir. Oseltamivir, Ribavirin in patients with COVID-19; but none of which showed efficacy of antiviral therapy. Such current findings impede researchers from recommending an appropriate and effective antiviral therapy against COVID-19, making it a serious concern for the global community. DISCUSSION In the present pandemic and any future epidemics, all the related authorities should pursue many more RCTs, cohort and case series for a prospective outcome in the management and treatment guidelines.

Abstract
Femoral fractures are frequent in the pediatric population. Treatment options are based on the patient's age, fracture pattern, type of trauma and associated soft tissue injury. The traditional treatment method for pediatric femoral shaft fracture has been traction and spica casting. The immediate spica cast is safe and effective for children up to 6 years of age with isolated femoral fracture and acceptable reduction. Patients between 6 and 10 years of age can also be treated with spica casting with or without traction. This prospective study was done in the department of Orthopaedics, Mymensingh Medical College Hospital, Mymensingh, Bangladesh form from July 2015 to June 2019 to evaluate the outcome of closed reduction and internal fixation by titanium elastic nailing for fracture shaft of femur. Twenty patients, all presenting with fresh diaphyseal fractures of femur, treated with closed reduction and internal fixation by titanium elastic nailing. These patients were prospectively evaluated over a period of at least 18 months. Fractures were classified according to Association of Orthopaedics (AO) classification of shaft of femur fractures. According to AO classification, all were A1, A2, A3 fractures. Average age of the patients was 11±2.7 years; range was 6 to 16 years. There were 15 males and 5 females. Out of 20 cases treated with this method, stable fixation and union was achieved in all of them. Radiological union was achieved at an average of 10±2.3 weeks (8-15 weeks). The results were excellent in twelve patients (60%), successful in five (25%) and poor in three patients (15%) as per the scoring criteria for TEN. The effective treatment of diaphyseal fractures of the femur is intramedullary fixation by titanium elastic nailing in patients of the 6-16 years age group.

Abstract
More than 120,000 anterior cruciate ligament (ACL) injuries occur every year in the United States, mostly during the high school and college years. The incidence of these injuries is slowly increasing, especially in females. This is likely caused by their increasing participation in high school and other organized sports. In addition, several studies have shown that female athletes are at an increased risk of ACL injury in sex comparable sports. The goal of this study was to evaluate the functional outcome of Arthroscopic anterior cruciate ligament reconstruction using Bone-Patellar tendon- Bone autograft. 25 patients with chronic ACL deficient knee presenting to Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from January 2018 to December 2019 were included in the study. The patients with severe osteoarthritis (OA) knee, local active infection and systemic disease, intraarticular fracture of knee that might influence the study results were excluded from the study. Bone patellar tendon bone graft was harvested from ipsilateral knee. The patient was followed till 6 months with specified program of rehabilitation. Results were evaluated by an independent examiner using radiography, subjective and objective evaluation. Assessment using Lysholm's score was 50 (42-63) preoperatively and 90.8 (63-97) at the latest follow up (p<0.005). No patient complained of instability at latest follow up. The quadriceps muscle showed atrophy at final follow-up. Five Patients complained of anterior knee pain. We found no graft displacement on follow up radiographs. Osteo-integration occurred in all cases. ACLR with a BPTB graft can stabilize the knee without loss of motion by closely mimicking the native ACL without any hazards and additional complications. It is useful in high demand patients and cost effective option with high patient satisfaction rate for reconstruction of ACL.

Abstract
The Sundarbans is the only mangrove habitat in the world to support tigers Panthera tigris, whose persistence there is believed to be dependent on a very limited number of prey species. Conservation managers therefore need to understand how tigers utilise available prey species on a spatial scale in order to formulate a prey-based protection strategy for this global-priority tiger landscape. A total of 512 scat samples were collected during a survey of 1984 km2 of forest across 4 sample blocks in the 6017 km2 of the Bangladesh Sundarbans. Analysis of scat composition and prey remains reliably identified 5 major prey species, of which spotted deer Axis axis and wild pig Sus scrofa contributed a cumulative biomass of 89% to tiger diet. Tiger preference for prey species was highly skewed towards spotted deer and wild pig, but the relative contribution of these 2 species differed significantly across the 4 study areas, which spanned the Sundarbans, demonstrating important spatial patterns of tiger prey preference across the Sundarbans landscape. Given the comparatively limited number of prey species available to support the dwindling tiger population, different strategies are needed in different parts of the Sundarbans to support tiger populations and to protect spotted deer and wild pig populations from unabated poaching.

Abstract
The physical, psychological and financial burden of skin disease in low- to middle-income countries, where access to skincare is limited, is poorly understood. A group that we know very little about in this regard are refugees. There are limited data on the range of skin diseases and skincare needs of this group. To better understand the skincare needs of the displaced Rohingya population residing in the Kutupalong refugee camp, Bangladesh, we collected data on demographics, living conditions and range of dermatoses. In the 380 patients assessed, fungal skin infections, predominantly dermatophytes, were by far the most common skin disease seen (n = 215), followed by dermatitis (n = 81). Skin disease can be the presenting feature in many systemic conditions and may cause significant secondary complications itself. Developing a better understanding of the skincare needs of the refugee population is essential for future healthcare planning for this vulnerable group.

Abstract
The sudden outbreak of a novel coronavirus in 2019 in Wuhan, China, that rapidly provoked a global concern, marked as the third attack of corona virus in the human society that affected the global healthcare system as well as the global economy. Until and unless an effective vaccine is discovered against the virus, the pharmacological intervention by different antivirals is in the run for remedy. The aim of this systematic review was to evaluate the role of favipiravir along with its safety and efficacy for the patients who are suffering from severe acute respiratory distress syndrome due to CoronaVirus-2 (SARS-CoV-2) as re-purposeful use. We searched PubMed, EMBASE for randomized controlled trials (RCTs), cilicaltrial.com for registered on going trails to evaluate the pros and cons of using favipiravir in COVID-19. After vigorous searching, screening and sorting of 314 articles for completed and published scientific evidences in electronic database, there were only 2 completed and published randomized control trials (RCT) and 17 ongoing or unpublished trials found until June 2020. The main outcome measures were viral clearance, clinical improvement and adverse events reported and published on 147 patients infected with SARS-CoV2. The 2 completed RCTs showed significantly better treatment effects on disease progression, viral clearance, improved the latency to relief for pyrexia and cough on favipiravir treated patients. Adverse effects caused Favipiravir are mild and manageable. Although 9 more RCTs and cohort studies are supposed to be completed by this time that may unveil some evidence for use of anti-RNA-viral drug favipiravir against influenza or Ebola to re-purposing against COVID-19 as adopted in different treatment guidelines.

Abstract
Variety of conditions may be responsible for low back pain but lumber spinal canal stenosis is an important cause of low back pain. Lumber spinal canal stenosis usually presents with low backache with neurogenic claudication and shortness of walking distance in adult patient. Surgical management of lumbar spinal canal stenosis by decompression surgery is effective method. This prospective interventional study was performed in patient with clinical features like low back pain with radicular pain, neurogenic claudication, signs of root compression, positive MRI findings attending in department of Orthopaedic Surgery Mymensingh Medical College Hospital and Private Hospital from July 2016 to June 2019. Thirty patients were evaluated among those 20(66.6%) were 50 years and above. The mean age was 47.5±1.6 years. Male to female ratio was roughly 8:1. Almost all of the patients had low backache with radiation to the back of the thigh and leg with motor weakness (60%). About 66.6% of the patients had sensory deficit and 83.3% had neurogenic claudication. Majority (80.0%) of the patients at presentation had a suffering of 12 or >12 months. The mean duration of suffering was 14.7±5.1 months. About 55% of the patients were able to perform heel-walking and 36.0% tip-toe walking. Nearly 57% of the patients had sensory deficit along the distribution of 1st sacral nerve and 53.3% along the distribution of lumber 5 nerves. Diagnosis shows that 16.6% of patients had L4 lesion, 50% L5, 10.0% patients had L4 & L5 and 46.6% S1. Laminectomy was done in 26.6% of patients, laminectomy and disectomy in 33.3% and laminectomy, discectomy & foraminal decompression in 40.0% of patients. Twenty five (83.5%) of patients was free from symptoms. Eighty percent (80.0%) of patients shows minimal disability and 20.0% moderate disability on the basis of Oswestry Disability Index, while by MacNab criteria, most (80%) of patients was excellent, 10% good and another 10% fair. Repeated measure ANOVA statistics showed that mean Oswestry score decreased significantly from 54.5% at baseline to 22% at the end of 1 year (p<0.001).

Abstract
Background:Chikungunya virus (CHIKV) infection is an emerging disease which is responsible for several epidemics around the world1. Systematic review and meta-analysis had shown that approximately 25% of cases of Chikungunya(CHIK) would develop CHIK-Chronic Inflammatory Rheumatism and 14% would develop persistent arthritis (or spondylitis)2.Objectives:To describe the frequency of the clinical patterns of chronic arthritis & to characterize the clinical symptoms in a Bangladeshi cohort of CHIK patients 12months post-infection.Methods:In 2017, a Chikungunya outbreak occurred in Dhaka, Bangladesh, during which a prospective cohort of CHIK patients with confirmed diagnosis was constituted. A longitudinal follow up of 60 patients from an initial cohort of 142 patients, attending the out-patient department of Rheumatology, BSMMU, was done. Patients having arthritis/ arthralgia or both lasting more than 3 months were considered as chronic cases. Their baseline and follow-up symptoms at 3m, 6m and 12months were evaluated. Functional status was assessed with the Bengali Version Health Assessment Questionnaire (HAQ).Results:Of the initial 142 patients enrolled in the study, 135(95.1%) had CHIKV-IgM and 29(20.4%) had IgG positive. Patients that followed up in-person were predominantly adult (age 43.73 ± 11.09 years) and female 34 (56.7%). The majority of the patients 35 (58.3%) had undifferentiated arthritis. After three months, 8 (16.3%) had oligoarthralgia, 26 (53.1%) had polyarthralgia and 8 (16.3%) had polyarthralgia with oligoarthritis. At the end of one year, 13 (21.7%) patients underwent complete remission. Among the 47 patients, 21 had joint involvement where 11(52.4%) had polyarthralgia, 5(23.8%) had polyarthralgia with oligoarthritis, 5 (23%) had oligoarthralgia and 4 (19%) had monoarthralgia. Among the 47 patients, mild, moderate and severe functional disability was present in 89.4%, 6.4% and 4.3% patients respectively.Conclusion:After one year of follow up, one-third of the patients remained symptomatic. Polyarthralgia was the predominant clinical feature. Mild functional disability was also observed in a significant number of patients.References:[1]Ali Ou Alla S, Combe B.

Abstract
Chronic Obstructive Pulmonary disease (COPD) is a heterogenous respiratory disease characterized by a progressive, not fully reversible airflow limitation associated with an abnormal inflammatory response of the lung to noxious stimuli. It is a disease presenting with pulmonary inflammation as well as a systemic one. Measurement of inflammatory marker is difficult but platelet count estimation is easy and less costly. This descriptive, cross-sectional study was carried out at Department of Medicine, Mymensingh Medical college Hospital, Mymensingh, Bangladesh for a period of twelve months among fifty-nine COPD patients. Data were collected through interview, physical examination and laboratory investigations. Statistical analysis was performed using SPSS version 22.0 for consistency and completeness. Age range of the patients was 40 to 49 years with a mean of 56.3±10.9 years. Age group 40-49 years contained the highest number (19; 32.3%) of patients. Majority 57(96.6%) of the respondents were male. Thirty seven (62.7%) of patients were illiterate. Majority 56(94.9%) of patients resided in rural area, of them most 38(64.4%) were farmers. According to Spirometric measurement among 59 respondents of COPD patient, 3(5.1%) were in GOLD stage-I, 9(15.3%) in GOLD stage-II, 27(45.8%) in GOLD stage-III and 20(33.9%) in GOLD stage IV group. Mean platelet count (10³/μl), 241.6±86.5 was found in mild, whereas 315.0±47.7 in moderate, 337.2±76.3 in severe, and 412.4±67.5 in very severe group of COPD patients. So increase in platelet count is statistically significant in severity of COPD. In conclusion, platelet count measurement is less costly to categorize COPD and may be a diagnostic marker.

Abstract
BACKGROUND: The study was conducted in BRAC-administered areas of the Bangladesh National Tuberculosis (TB) Programme (42 of 64 districts). According to the 2013-2017 financial support scheme, direct costs due to TB diagnosis were reimbursed among economically disadvantaged people with presumptive smear-negative pulmonary (PTB) and extrapulmonary TB (EPTB).OBJECTIVE: To describe the implementation of the scheme and associated changes in case notification.DESIGN: This was a descriptive study involving programme data.RESULTS: Between 2013 and 2017, persons reimbursed reduced from 125 680 to 88 763, and the case detection ratio increased from 18% to 24%. The number of patients with presumptive EPTB who were reimbursed decreased from 5024 to 3484. More than 95% were reimbursed for chest radiograph, fine-needle aspiration cytology and biopsy. However, large numbers of ancillary investigations were also reimbursed. During 2013-2017, the observed national quarterly new smear-negative PTB case notification rates (CNRs) were significantly higher than the forecasted CNRs (based on CNR trends during 2008-2012). New EPTB and all form TB CNRs increased but not significantly.CONCLUSION: Implementation of the financial support scheme was accompanied by a significant improvement in new, smear-negative PTB notification. The absence of a comparison arm was a key limitation, but comparison was not possible as the scheme was implemented in all districts.

Abstract
Distal humeral fractures are relatively rare injuries that constitute approximately 2% of all fractures which occur due to high energy trauma in young males. Because they involve the articular surface and usually cause an instable elbow, surgical treatment is necessary for the recovery of elbow functions in the majority of cases. The principles of absolute stabilization and early mobilization in the elbow are of more importance than in any other joint. As the AO classification, nonunion and implant loosening is more common in type C fractures of the distal humerus involving the joint surface. Aim of this prospective study was to evaluate the outcome of "Double Tension Band wiring" method for the treatment of intercondylar fractures of humerus and was conducted in a tertiary hospital of Bangladesh from July 2017 to June 2019. Twenty five patients, all presenting with fresh fractures of the distal humerus, treated with double tension band wiring. These patients were prospectively evaluated over a period of at least 6 months. Fractures were classified according to Jupiter classification and AO classification of distal humeral fractures. Due to AO classification, total fractures were C1 fractures. Average age of the patients was 56.20 years (32-70 years). There were 20 males and 5 females. Out of 25 cases treated with this method, rigid fixation and union was achieved in all of them. The average tourniquet time was 69 minutes range was minimum 50 minutes and maximum 120 minutes. Radiological union was achieved at an average of 14.2 weeks (10-18 weeks). Average range of motion was 112.8 degrees (107-116). Excellent to good results were seen in almost 86% of cases as per the Mayo Elbow performance score at 6-month follow-up. Wound infection had been occurred in 2(8%) cases, ulnar nerve neuropathy had been occurred in 1 case, delayed union of olecranon process of ulna had been occurred in 1(4%) case, implant failure had been occurred in 2(8%) cases, heterotrophic ossification had been occurred in 2(8%) cases, varus valgus instability had been occurred in 1(4%) case, gun stock deformity had been occurred in 2(8%) cases. Double tension band wiring is a reliable, less demanding and cost effective method of fixation of intercondylar fractures of humerus.

Abstract
Tourism especially nature based tourism is increasing throughout the world day by day. The Sundarbans Reserve Forest (SRF) in Bangladesh is a suitable place for developing tourism. The purpose of the study was to find out the attitudes of local people’s towards community based eco-tourism (CBET) in the Sundarbans. The study was carried out by a questionnaire survey with purposive selection based on diversity of occupation and sex in that area. A 5- point rating Likert scale was used to measures the local people’s attitude towards community based eco-tourism. Most of the people of the study are poorly based on income and depends on the forest as well as are fisherman among male and housewife among women. Natural beauty of this area, scope to watch wildlife, tourist security, house or eco-cottage quality, toilet and bathing facilities are favorable as well as communication and infrastructure facilities are an obstacle for developing CBET here. CBET will increase alternative job opportunities and income as well as it will reduce disturbance of forest and illegal harvesting according to the respondents. Forest Department is cooperative and tourists are more conscious now than before. People are now satisfied with CBET and keen to involve with this. This research is important for tourism policymakers in Bangladesh for their decisions.
