Transcatheter Aortic Valve Replacement in Bicuspid Aortic Valve: A Case Report

Among other valvular heart disease Aortic stenosis (AS) is the most common in the developed world. Transcatheter Aortic Valve Replacement (TAVR) is most acceptable treatment option for patient with severely calcified aortic stenosis with high and intermediate risk group. Among several challenges, one of the main challenges is to deal with bicuspid aortic valve (BAV). Non-circular annulus, bulky leaflets leading to perivalvular leaks and risk for rupture and often very severe calcification may contribute to periprocedural strokes leading to poor clinical outcome. This case, a 68-year-old woman with a history of type 2 diabetes mellitus (DM), hypothyroidism, bicuspid aortic valve and severe aortic stenosis, bronchial asthma, who had repeatedly refused any suggestion for open heart surgery, was our volunteer candidate for TAVR. After successful TAVR the peak pressure gradient decreased from 100mmHg to 17mmHg. So, TAVR could be a viable option for highly selected patients with severe aortic stenosis and bicuspid aortic valve who have favourable anatomy.

Relationship of Conduction Defects and In-Hospital Outcome after Acute ST Segment Elevation Myocardial Infarction

The presence of conduction defects complicating acute myocardial infarction (MI) is relatively frequent and is associated with increased short and long term mortality. Thrombolytic therapy has been established to reduce the mortality in acute MI, however its role in reducing the incidence of conduction defects is less clearly defined. Morbidity and mortality associated with conduction defects also remain unchanged. This study was aimed to assess the correlation between conduction defects and adverse in-hospital outcome of patients with acute ST segment elevation MI. This cross sectional descriptive type of observational study was conducted among 100 purposively selected patients with acute ST segment elevation MI in the coronary care unit (CCU) of Mymensingh Medical College Hospital, Bangladesh from June 2012 to March 2013. The patients were divided into two groups depending on the presence or absence of conduction defects namely Group A- 40 patients with conduction defects and Group B- 60 patients without conduction defects. Highest number of the patients (36.0%) was in the age group of 45-55 years. In case of inferior MI, age groups 45-55 years and 55-65 years had equal number of patients (30.4%). Only 2.0% patients were in age group of 75-85 years and this group had only inferior MI. Total number of female patients were 16(16.0%). Female patients had more inferior MI (17.4%) than anterior MI (15.9%). Number of MI patients was slightly more in inferior MI (46.0%) than anterior MI (44.0%). Group B had equal number of patients in both anterior and inferior MI. Conduction defects were more common in inferior MI (43.5%) than anterior MI (40.9%). Atrio-ventricular conduction defects were more common in inferior MI whereas intra-ventricular conduction defects were more common in anterior MI. Complete heart block (CHB) was more prevalent in inferior MI. Complications were more common in Group A (65.0%) than Group B (18.3%). In terms of complications the difference between two groups were significant (p<0.001). Group A showed higher rate of mortality (20.0%) than Group B (3.3%). In cases of anterior MI difference in mortality between Group A and Group B was highly significant (p<0.001). Conduction defects in the setting of acute MI are a common finding. Atrio-ventricular conduction defects occur more frequently in inferior MI whereas intra-ventricular conduction defects were more frequently encountered in anterior MI. Patients with conduction defects had more complications than those without conduction defects. Presence of conduction defects significantly increases the mortality of patients with anterior MI.

Comparison between Lichtenstein And Laparoscopic Totally Extraperitonial (TEP) Tension Free Mesh Repair of Inguinal Hernia

To compare the outcome of the laparoscopic totally extra peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia. This study was conducted as a prospective comparative (Quasi experimental) study from January 2010 to December 2010 at Combined Military Hospital (CMH), Dhaka, Bangladesh. A total of 100 male patients aged 24 to 70 years who underwent laparoscopic totally extra-peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia were included in this study. Data of operating time, intraoperative and short-term postoperative complications, postoperative pain, postoperative hospital stay and return to normal activity were recorded and analyzed with SPSS program. Mean age of the patients was 51.39±15.099 years in OLMR group (Group A) and 47.10±9.338 years in Lap TEP group (Group B). Mean operating time was longer in Laparoscopic TEP group (Group B, 57.67±6.915 minutes) then open Lichtenstein mesh repair group (Group A, 50.56±6.292 minutes). Patient in the Lap TEP group (Group B) experienced less post operative pain, less post operative complications, shorter hospital stay and early return to normal activity then OLMR group (Group A). One patient (3.33%) in group B needed conversion to open Lichtenstein method. Two (6.66%) patients developed pneumoperitoneum in Group B (Lap TEP repair). Superficial wound infection developed in five (7.14%) patients in OLMR group (Group A) and two (6.66%) patients in Lap TEP group (Group B). In Laparoscopic TEP group (Group B) and Lichtenstein group (Group A), patients return to normal activity within on an average 07 and 11 days respectively. Laparoscopic totally extra peritoneal (TEP) mesh repair technique was associated with less post operative pain, less post operative complications, shorter hospital stay, faster recovery with early return to normal activity compared with Lichtenstein tension free mesh repair of inguinal hernia.

Human health implications of trace metal contamination in topsoils and brinjal fruits harvested from a famous brinjal-producing area in Bangladesh

A study was undertaken to determine the contents of trace metals in 60 topsoils and 80 brinjal fruits samples from a famous brinjal-producing area of Bangladesh using atomic absorption spectrophotometer. The study also looked at soil pollution levels, dietary intake of nutritionally important trace elements, and human health risks from toxic metals induced by dermal soil exposure and consumption of brinjal. The content of Pb, Ni, Cd, Cu, Fe, Mn, and Zn in brinjal fruits harvested from farmer′s fields ranged from 0.204–0.729, 0.031–0.212, < 0.010–0.061, 1.819–2.668, 3.267–5.910, < 0.010–0.866 and 2.160–3.846 µg g^-1, respectively, while the amount of Cr was negligible. The calculated enrichment factors showed that 70, 50, and 25% of soil sampling sites had values in the 2.00–5.00 range for Pb, Zn, and Cd, respectively, while 30% of sites had values > 5.00 for Cd, indicating moderate to significant enrichment of these metals in the soil. The study also revealed that brinjal consumption provides a tiny amount of nutritionally important trace elements required for an adult human. Regarding the computed incremental lifetime cancer risks (ILCR), the study revealed that the values for Pb and Ni in all samples and Cd in 40% of samples were several hundred times higher for males and females than the USEPA threshold level due to oral ingestion of brinjal fruits. In contrast, dermal exposures to soil trace elements were within an acceptable range. The PCA results revealed that the contents of Cd, Pb, Ni, and Cu in soils showed strong positive correlations with those elements present in brinjal. The current study suggests future traceability research, focusing on pinpointing potential entry routes for toxic elements into the vegetable food chain.

Estimation of Serum Lipid Profile among Patients Admitted with Myocardial Infarction in a Tertiary Level Hospital of Bangladesh

Different studies worldwide showed that dyslipidaemia is involved in the pathogenesis of ischemic heart diseases (IHD). This cross sectional descriptive type of observational study was carried out at Mymensingh Medical College Hospital during the period of six months from January 2021 to September 2021 to estimate the lipid profile among patients admitted in the coronary care unit (CCU) with myocardial infarction (MI). Data were collected from purposively selected 343 patients with MI by face to face interview and laboratory investigations using a case record form. Informed written consent of participants was taken prior to interview. Data were analyzed by using SPSS version 21.0. The study results revealed that mean age of the patients with myocardial infarction was 53.16 years with a standard deviation of 11.68 years. Majority of them (284, 82.8%) were male and the remaining (59, 17.2%) were female. Proportion of risk factors for ischaemic heart disease (IHD) were estimated and found that 244(71.1%) patients were smoker; 150(43.7%) had hypertension and 110(32.2%) had family history of IHD. Ninety nine (28.9%) patents were obese with BMI ≥25kg/m². Eighty three (24.2%) patients had diabetes mellitus; 66(19.2%) lead sedentary life and 61(17.8%) patients with myocardial infarction had dyslipidaemia. Mean LDL of patients with myocardial infarction was 103.65±39.73mg/dl; mean total cholesterol (TC) was 189.44±45.41mg/dl; mean TG was 243.11±205.19mg/dl and mean HDL was 39.29±8.98mg/dl. LDL was increased in 10(2.9%) patients; total cholesterol was raised in 121 (35.3%) patients and TG was raised in 195(56.9%) patients. HDL was raised in 26(7.6%) patients and it was lowered in 57(16.6%) patients. Mean LDL, TC, TG and HDL of younger (≤45 years) and older (>45 years) patients were compared and t-test showed no significant difference (p>0.05). Similarly mean LDL, TC, TG and HDL of male and female were compared and again t-test showed no significant difference (p>0.05). Though the pattern of lipid profile was found similar in younger and older patients and in males and females, a significant number of patients (61, 17.8%) with MI had dyslipidaemia which should be address by dietary and lifestyle modification.

Psychological Assessment of Health-Care Workers Working during COVID-19 Pandemic Condition in Bangladesh

The study was aimed to assess the psychological aspects and relevant factors of the health-care workers (HCWs) working in COVID 19 pandemic condition in Bangladesh. This online cross-sectional survey was conducted from different tertiary, secondary and primary hospitals in Bangladesh. Eligible 638 HCWs who were directly involved in the caring of confirmed or suspected COVID-19 patients were recruited in this study. The mental health was assessed by the Patient Health Questionnare-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7) and Athens Insomnia Scale (AIS). High frequency of depression 536(84.0%), anxiety 386(60.5%) and insomnia 302(47.3%) was found among the HCWs, which were significantly higher in physicians (p<0.001) than nurses. Moderate to severe depression was significantly higher in female, whereas minimal to mild depression was significant in male HCWs (p=0.014). Symptoms of depression (p<0.001), anxiety (p<0.001) and insomnia (p=0.004) were significantly higher among the HCWs of primary and secondary compared to the tertiary level. The HCWs developed psychological trauma due to family health (45.3%) and contagious disease property (66.6%). After adjusting confounders, multivariable logistic regression analysis showed that physicians and HCWs of secondary hospital had significant symptoms of severe depression (OR=2.95, 95% CI=0.50-17.24; p<0.001), anxiety (OR=2.64, 95% CI=0.80-8.72; p<0.001) and insomnia (OR=2.67, 95% CI=1.23-5.84; p=0.018); whereas female HCWs had more risk of developing symptoms of severe insomnia (OR= 1.84; 95% CI=1.23-2.75; p=0.003). High rate of depression, anxiety and insomnia was found among HCWs working in the COVID-19 pandemic condition in this survey.

Finding gaps in routine TB surveillance activities in Bangladesh

BACKGROUND :

TB was the leading cause of death from a single infectious pathogen globally between 2014 and 2019. Fine-scale estimates of TB prevalence and case notifications can be combined to guide priority-setting for strengthening routine surveillance activities in high-burden countries. We produce policy-relevant estimates of the TB epidemic at the second administrative unit in Bangladesh.

METHODS :

We used a Bayesian spatial framework and the cross-sectional National TB Prevalence Survey from 2015–2016 in Bangladesh to estimate prevalence by district. We used case notifications to calculate prevalence-to-notification ratio, a key metric of under-diagnosis and under-reporting.

RESULTS :

TB prevalence rates were highest in the north-eastern districts and ranged from 160 cases per 100,000 (95% uncertainty interval [UI] 80–310) in Jashore to 840 (UI 690–1020) in Sunamganj. Despite moderate prevalence rates, the Rajshahi and Dhaka Divisions presented the highest prevalence-to-notification ratios due to low case notifications. Resolving subnational disparities in case detection could lead to 26,500 additional TB cases (UI 8,500–79,400) notified every year.

CONCLUSION :

This study is the first to produce and map subnational estimates of TB prevalence and prevalence-to-notification ratios, which are essential to target prevention and treatment efforts in high-burden settings. Reaching TB cases currently missing from care will be key to ending the TB epidemic.

Association of Body Mass Index with Angiographic Severity of Coronary Artery disease in patients with Acute Coronary Syndrome

Coronary artery disease (CAD) is the leading cause of death in developed and developing countries. Associated co-morbidities like diabetes, hypertension and obesity are making the situation worse. WHO enlisted obesity as an epidemic which also affects a great number of young population. Some recent studies showed the presence of an apparent paradoxical relationship between obesity and cardiovascular prognosis in certain subsets of patents. As BMI is an established marker of obesity; an attempt has been made to assess relationship between BMI and angiographic severity of coronary artery disease in Acute Coronary Syndrome (ACS) patients of Bangladeshi origin. To assess the association between body mass index and angiographic severity of coronary artery disease in patients with acute coronary syndrome; this cross sectional analytical study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital (MMCH) and Bangabandhu Sheikh Mujib Medical University (BSMMU) from December 2016 to February 2018 among purposively selected 65 patients. Relevant ethical issues were taken into consideration. Coronary angiogram was done in the same index hospitalization period. After coronary angiogram performed patients were grouped into two groups according to their BMI. Patients with BMI <25kg/m² as Group I and those ≥25kg/m² as Group II. Angiographic severity of coronary artery disease was assessed by vessel score and Syntax score. Mean age of Group I was 54.45±10.42 years, while in Group II it was 50.76±8.89 years reflecting the early presentation of higher BMI patients. Male to female ratio was 12:1. Mean BMI of Group I and Group II was 22.56±1.59 and 28.67±2.64 respectively. In Group I, 10(25.0%) had single vessel lesion, 15(37.5%) had double vessel lesion and 14(35.0%) had triple vessel lesion, while in Group II, 6(24.0%) had single vessel lesion, 12(48.0%) had double vessel lesion and 5(20.0%) had triple vessel lesion. Mean Syntax score of Group I and Group II was 13.18±8.45 and 10.42±7.14 respectively. Patients in the increasing BMI class had a higher prevalence of diabetes, hypertension and dyslipidaemia. A negative correlation was observed between BMI and angiographic severity (Vessel score, Syntax score and HRCA e.g. LM disease) of CAD indicating that patients with higher BMI had a lower coronary artery disease (CAD) severity than their normal BMI counterparts. Patients with high BMI have a lower CAD severity than usually expected. After adjustment for co-morbidities, BMI was not found as an independent predictor of severity of coronary artery disease.

Combining ability analysis in bitter gourd (Momordica charantia L.) for potential quality improvement

Combining ability analysis provides useful information for the selection of parents, also information regarding the nature and magnitude of involved gene actions. Crops improvement involves strategies for enhancing yield potentiality and quality components. Targeting the improvement of respective characters in bitter gourd, combining ability and genetic parameters for 19 characters were estimated from a 6×6 full diallel analysis technique. The results revealed that the variances due to general combining ability (GCA) and specific combining ability (SCA) were highly significant for most of the important characters. It indicated the importance of both additive and non-additive gene actions. GCA variances were higher in magnitude than SCA variances for all the characters studied indicating the predominance of the additive gene effects in their inheritance. The parent P2 (BG 009) appeared as the best general combiner for earliness; P1 (BG 006) for number of fruits, average single fruit weight and fruit yield; P4 (BG 027) for node number of first female flower and days to seed fruit maturity; P3 (BG 011) for fruit length and thickness of the fruit flesh; P5 (BG 033) for 100-seed weight; and P6 for number of nodes per main vine. The SCA effect as well as reciprocal effect was also significant for most of the important characters in different crosses.

Role of High Neutrophil Lymphocyte Ratio as an Independent Predictor of Adverse In-Hospital Outcomes in Patients with First Attack of ST-Elevation Myocardial Infarction Thrombolysed with Streptokinase

Atherosclerosis is the pathognomic sign of ischaemic heart disease. Inflammation of the coronary artery contributes to the development of atherosclerosis. Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict the risk of CAD and associated events in patients with ST-Segment elevation myocardial infarction (STEMI). This study was done to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in predicting in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase (STK). This cross sectional descriptive type of study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from August, 2017 to October, 2018. The STEMI patients, thrombolysed with STK had blood samples at admission, analyzed for complete blood counts and NLR calculated. They were grouped into two, low and high NLR, taking 4.50 as cut-off value. Chi square test was used to compare rate of adverse events and death in hospital stay. Logistic regression analysis was used to estimate predictive ability of NLR for in-hospital cardiac events. A total of 87 (39.90%) patients had complications. Patients in high NLR group had higher rate of complications (48.3% vs. 22.5%, p<0.001) in hospital than those in low NLR group. Arrhythmias (21.1% vs. 9.9%, p<0.041), heart failure (27.9% vs. 14.1%, p=0.024), cardiogenic shock (16.3% vs. 4.2%, p<0.011), death (6.8% vs. 2.8%, p=0.227), re-infarction /post MI angina (4.1% vs. 0.0% p=0.084) occurred more in high NLR group. Mean NLR was significantly different between Group I and Group II (3.11±0.84 vs. 10.20±6.08, p<0.0001). Multivariate regression analysis showed NLR an independent predictor of in-hospital adverse cardiac events (p<0.0001). High on admission NLR is an independent predictor for in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase.

Accuracy of Magnetic Resonance Cholangiopancreatography in Case of Biliary Obstruction Comparing Post-operative Findings: A Study of 50 Cases

Complete assessment of obstructive jaundice requires the use of various imaging modalities that are required to detect the cause and level of obstruction thus helping in treatment planning. Magnetic Resonance Cholangio Pancreatography (MRCP) is a current available technology which is a non-invasive technique that visualizes the gallbladder, biliary tree and pancreatic duct and also provides information about surrounding structures. This study was done to correlate the MRCP findings with post-operative result and thereby demonstrate the specificity, sensitivity and efficacy of MRCP as an accurate investigatory tool for biliary obstruction. Total of fifty (50) patients of clinically diagnosed obstructive jaundice were studied from March 2017 to August 2017 in the Department of Radiology and Imaging, Combined Military Hospital, Dhaka, Bangladesh. In all these cases, USG was the initial screening investigation followed by MRCP. Cause and level of obstruction were evaluated using MRCP findings. MRCP results were correlated with surgical findings and few cases also with direct ERCP findings. Statistical analysis was done to see the sensitivity, specificity, accuracy, positive and negative predictive values of MRCP in diagnosis of biliary obstruction. In this study, USG detected level of obstruction in 56% (28 out of 50) cases. USG could detect causes of obstruction in 100% (02 out of 02) cases of choledocal cyst and 66.67% (02 out of 03) benign stricture, 60% (03 out of 05) cases of periampullary carcinoma, 57.70% (06 out of 14) cases of choledocholithiasis, and 42.86% (15 out of 26) cases of cholangiocarcinoma. On the other hand, MRCP detected level of obstruction in 98% (49 out of 50) cases. MRCP could detect causes of obstruction in 100% cases of cholangiocarcinoma, choledocholithiasis, benign stricture and choledocal cyst and 80% (04 out of 05) cases of periampullary carcinoma. In this study, ERCP could detect causes of obstruction in 32 cases of choledocholithiasis and benign stricture, but in case of cholangiocarcinoma ERCP was failed in 3 cases. In this study, for detection of cause of obstruction, ERCP had the highest sensitivity (97.79%); followed by MRCP (96.65%) and USG (60.25%). The overall diagnostic accuracy for detection of cause of obstruction was the highest for ERCP (95.50%); followed by MRCP (94.50%) and USG (64.50%). MRCP can be done in a short duration and is a noninvasive diagnostic modality compared to ERCP. MRCP needs to be advocated as a viable and non-invasive alternative with compararable sensitivity and specificity to ERCP.

Salinity Influences Plant-Pest-Predator Tritrophic Interactions

Climate change-induced salinity intrusion into agricultural soils is known to negatively impact crop production and food security. However, the effects of salinity increase on plant-herbivore-natural enemy systems and repercussions for pest suppression services are largely unknown. Here, we examine the effects of increased salinity on communities of rice (Oryza sativa), brown planthopper (BPH), Nilaparvata lugens, and green mirid bug (GMB), Cyrtorhinus lividipennis, under greenhouse conditions. We found that elevated salinity significantly suppressed the growth of two rice cultivars. Meanwhile, BPH population size also generally decreased due to poor host plant quality induced by elevated salinity. The highest BPH density occurred at 2.0 dS/m salinity and declined thereafter with increasing salinity, irrespective of rice cultivar. The highest population density of GMB also occurred under control conditions and decreased significantly with increasing salinity. Higher salinity directly affected the rice crop by reducing plant quality measured with reference to biomass production and plant height, whereas inducing population developmental asynchrony between BPH and GMB observed at 2 dS/m salinity and potentially uncoupling prey-predator dynamics. Our results suggest that increased salinity has harmful effects on plants, herbivores, natural enemies, as well as plant-pest-predator interactions. The effects measured here suggest that the bottom-up effects of predatory insects on rice pests will likely decline in rice produced in coastal areas where salinity intrusion is common. Our findings indicate that elevated salinity influences tritrophic interactions in rice production landscapes, and further research should address resilient rice insect pest management combining multipests and predators in a changing environment.

May Measurement Month 2019: an analysis of blood pressure screening results from Bangladesh

According to the Non-communicable disease Risk Factors Survey of 2018, more than one-fifth (21.0%) of adults aged 25 years or older have hypertension and one-third of the adults did not have their blood pressure (BP) measured in their lifetime in Bangladesh. The National Heart Foundation of Bangladesh participated in May Measurement Month (MMM) 2017 and 2018 as well as this 2019 as a part of a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes worldwide. This opportunistic screening of voluntary participants aged ≥18 years was carried out from May to July 2019. Data were collected from 100 screening sites in 16 districts in Bangladesh. BP measurement, the definition of hypertension, and statistical analysis followed the MMM protocol. Data on 24 941 individuals were analysed. Among the participants, 12 658 (50.8%) were female. After multiple imputation, 6990 (28.0%) had hypertension. Among the 6990 participants with hypertension, 5007 (71.6%) were on antihypertensive medication and 5331 (76.3%) were aware of having hypertension. Among 6990 participants with hypertension, 3217 (46.0%) had controlled BP (<140/90 mmHg) and among the participants with hypertension and on antihypertensive medication, 64.2% had controlled BP. Opportunistic BP screening can identify significant numbers of people with raised BP and thus assist in the prevention of cardiovascular diseases.

Rehabilitation Approach of a Patient with Myositis Ossificans: Non-surgical Management, Hazard of being Unguided Over Exercised

Myositis ossificans (MO) is a condition where calcification occurs in the soft tissue as well as around the bone following fracture, vigorous exercise or trauma. Although it is a radiological diagnosis, it often leads physician to an incorrect or missed diagnosis as recurrent fracture. Frequently, it follows haemorrhage into the muscle in the tissue space. We report a 45 years old house-wife presented with the complaints of weakness of right side of body and pain with restricted range of motion (ROM) in right lower limb. She was a diagnosed case of recurrent stroke with rheumatic valvular heart disease. After discharge, vigorous physical exercise was done at home by local physiotherapist without appropriate guidance from physiatrist. Gradually pain was so severe that she didn't allow moving her right lower limb. Over the course of time, she became incapacite and bed bound. She denied any positive family history. With the hip and lower limb problems she consulted with orthopedic surgeon and was referred to Physical Medicine and Rehabilitation department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh for further management & rehabilitation. This case is presented to focus on hazard of being unguided, over-exercised and non-surgical management approach of this rare condition.

Prevalence and Pattern of Dyslipidemia in Diabetes Mellitus Patients Admitted in the Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh

Patients with Diabetes Mellitus are at high risk of cardiovascular events because of abnormal lipid metabolism. Dyslipidemia is common in patients with Diabetes Mellitus (DM). However; in Bangladesh this issue is not yet properly addressed. The aim of this study is to determine the prevalence and patterns of dyslipidaemia in patients with DM in a divisional city Mymensingh. This cross-sectional study was conducted in randomly selected eligible patients from the indoor registry of the Department of Cardiology, Mymensingh Medical College Hospital (MMCH), Bangladesh from April 2012 to March 2013. A well structured questionnaire and blood investigation for lipid profile and blood sugar were the tools of data collection from 120 randomly selected DM patients registered in the department of cardiology, MMCH. Out of 120 enrolled participants the prevalence of dyslipidemia in DM patients was 86.0%, prevalence of dyslipidemia in males was 88.0% while in females was 85.0% but the difference was not significant (p=0.42). Regarding age group, BMI and duration of DM, there is no significant association exists with dyslipidemia. About half of the studied DM patients have high serum total cholesterol level (50.83%), while 22.5% had low serum HDL-C levels and 35.0% had high serum LDC-C level, most of patients had serum triglyceride levels above normal range (67.5%) and so the common patterns of dyslipidemia in this study were serum triglyceride level followed by total cholesterol. High prevalence of dyslipidemia among diabetes mellitus in Mymensingh city were observed and so the common patterns of dyslipidemia is triglyceride followed by total cholesterol. This study emphasizes the importance of screening of lipid profile as these abnormalities may lead to development of cardiovascular diseases.

Molecular Detection of Human Brucellosis among Patients with Pyrexia of Unknown Origin

This study describes the molecular detection of human brucellosis among patients with pyrexia of unknown origin. It was a cross-sectional descriptive study and was carried out in the Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. Non-probability purposive type of sampling technique was used. Blood samples were collected from 400 pyretic patients from September 2018 to August 2019. BCSP31 Brucella genus-specific TaqMan real-time PCR and SYBR Green real-time PCR were undertaken for molecular detection. Out of 400 samples, 22 (5.5%) samples found BCSP31 Brucella genus-specific real-time PCR positive. The study revealed that a considerable number of brucellosis is present in rural areas among risk as well as non-risk group study population having definite male predominancy, most prone to develop among >40-80 years age group. Brucella genus and species-specific real-time PCR might be performed for confirmation and also to avoid unjustified costs, drug toxicity, and un-masking of other potentially dangerous diseases.

Relationship of Plasma Vitamin-D Level with Left Ventricular Ejection Fraction in Patients with First Attack of Acute Myocardial Infarction

It has been widely reported that vitamin D deficiency is associated with Coronary heart disease (CHD), especially acute Myocardial infarction (MI). Many factors are responsible for reduced Left ventricular ejection fraction (LVEF) and acute Left ventricular fraction (LVF) after acute MI. This cross sectional descriptive type of study was conducted in the Cardiology department of Mymensingh Medical College Hospital from October 2017 to March 2019 to investigate the relationship of plasma vitamin D with LVEF in patients with first attack of acute MI. Total 185 patients of first attack of acute MI were included considering inclusion and exclusion criteria. Fasting blood samples were analyzed for plasma vitamin D level. Sample population were grouped at first into two, normal and low vitamin D level, taking 30ng/ml as cut-off value, low vitamin D level is further subdivided into insufficiency (21-29ng/ml), deficiency (10-20ng/ml) and severe deficiency (<10ng/ml). LVEF among the patients was observed. LVEF was found 49.88±8.58% patients having normal vitamin D level (>30ng/ml), 47.60±8.24% of patients having vitamin D insufficiency (21-29ng/ml), 44.38±8.12% of patients having vitamin D deficiency (10-20ng/ml) and 40.61±8.64% patients having severe vitamin D deficiency (<10ng/ml), which was statistically significant (p<0.05). So, low plasma vitamin D level is associated with reduced LVEF in patients hospitalized with first attack of acute MI.

May Measurement Month 2018: an analysis of blood pressure screening results from Bangladesh

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. According to Non-communicable disease (NCD) Risk Factors Survey Bangladesh 2010, one-fifth (21.9%) of adults aged 25 years or more have hypertension. Almost one-third of the adult population did not have their BP measured in their lifetime in Bangladesh. National Heart Foundation of Bangladesh participated in May Measurement Month (MMM) 2018 as a part of a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes nationally. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May 2018. Blood pressure measurement, the definition of hypertension and statistical analysis followed the MMM protocol. Data were collected from 10 screening sites in 9 districts in Bangladesh. A total of 5208 individuals were screened during MMM18. After multiple imputation, 1750 (33.6%) had hypertension. Among the 1750 participants with hypertension, 1312 (75.0%) were aware of having hypertension. Among those that were not on antihypertensive medication, 15.2% were hypertensive and among those that were on antihypertensive medication 33.6% had uncontrolled hypertension. The present study showed that opportunistic screening can identify significant numbers of people with raised BP. A periodic public health programme at a national level needs to be initiated to increase hypertension detection and control rates and thus for prevention of cardiovascular diseases.

Bifidobacterium longum DS0956 and Lactobacillus rhamnosus DS0508 culture-supernatant ameliorate obesity by inducing thermogenesis in obese-mice

Excessive body fat and the related dysmetabolic diseases affect both developed and developing countries. The aim of this study was to investigate the beneficial role of a bacterial culture supernatant (hereafter: BS) of Lactobacillus and Bifidobacterium and their potential mechanisms of action on white-fat browning and lipolysis. For selection of four candidates among 55 Lactic acid producing bacteria (LAB) from human infant faeces, we evaluated by Oil Red O staining and Ucp1 mRNA quantitation in 3T3-L1 preadipocytes. The expression of browning and lipolysis markers was examined along with in vitro assays. The possible mechanism was revealed by molecular and biological experiments including inhibitor and small interfering RNA (siRNA) assays. In a mouse model, physiological, histological, and biochemical parameters and expression of some thermogenesis-related genes were compared among six experimental groups fed a high-fat diet and one normal-diet control group. The results allow us to speculate that BS treatment promotes browning and lipolysis both in vitro and in vivo. Moreover, the BS may activate thermogenic programs via a mechanism involving PKA-CREB signaling in 3T3-L1 cells. According to our data, we can propose that two LAB strains, Bifidobacterium longum DS0956 and Lactobacillus rhamnosus DS0508, may be good candidates for a dietary supplement against obesity and metabolic diseases; however, further research is required for the development as dietary supplements or drugs.

Correlation of Mean Platelet Volume with ST Segment Resolution after Thrombolytic Therapy in Patients with ST Elevation Myocardial Infarction

Acute occlusive thrombosis of the coronary artery is the principal cause of myocardial infarction where platelets play an important role. Large size platelets, easily measured by mean platelets volume (MPV) are thrombogenic and commonly seen after ST-segment elevation myocardial infarction (STEMI). ST segment resolution has been shown as a simple non-invasive marker that reflects both epicardial and myocardial reperfusion following thrombolysis. The present study intended to investigate whether MPV on admission correlated with ST segment resolution following thrombolysis in STEMI patient. This cross-sectional analytical study was conducted in the department of cardiology, Mymensingh Medical College and Hospital (MMCH), Mymensingh, Bangladesh from December, 2016 to June, 2018. Total 284 patients with first attack of STEMI were included after considering inclusion and exclusion criteria. Sample population was divided into two groups, Group I - Patients with successful ST segment resolution (≥50%). Group II - Patients with impaired ST segment resolution (<50%). MPV on admission was estimated during estimation of Complete Blood Count (CBC) by Automated Haematology Analyzer & compared between two groups. Successful ST segment resolution (≥50%) was seen in 67% of patients after thrombolysis. Admission MPV was higher in patients with impaired ST segment resolution (<50%) group than patients with ≥50% ST-segment resolution group (12.42±0.89fl vs.10.35±0.77fl respectively, p=0.001). Statistically significant strong negative correlation between MPV and ST segment resolution percentage (r = -0.742, p=0.001) suggesting that the higher the level of MPV, the lower the ST segment resolution percentage in first attack of STEMI patients. Multivariate regression analysis found MPV level on admission as an independent predictor of ST segment resolution. The study concluded that high MPV on admission correlate with impaired ST segment resolution following thrombolysis in STEMI patients.

Association of Stress Hyper-Glycaemia on Outcomes of Hospitalized Non Diabetic Patients with First Attack of Acute ST Elevated Myocardial Infarction Underwent Thrombolysis

Coronary heart disease (CHD) is the most common cause of heart disease and serious cause of early death in developed countries around the world. Stress hyper-glycaemia has a bad prognostic implication in hospital outcomes in acute ST elevated myocardial infarction patients. It serves as a marker of myocardial damage, provides information about complications of acute MI and bad prognosis. The aim of this cross-sectional descriptive study was to find out prognostic implications of Stress hyper-glycaemia in non diabetic patients with first attack of acute ST elevated myocardial infarction underwent thrombolysis and conducted in the department of Cardiology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from June 2017 to May 2018. Total 249 first attack of Acute STEMI patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I: Patients with first attack of acute STEMI underwent thrombolysis with non diabetic stress hyper-glycaemia (Blood sugar >7.8mmol/L and HbA1c <6.5), Group II: Patients with first attack of acute STEMI underwent thrombolysis with non diabetic normo-glycaemia (Blood sugar <7.8mmol/L and HbA1c <6.5). In this study, in non diabetic Stress hyperglycemic patients' death was 5.7% and in non diabetic normo-glycemic patients death was 0.6%. It was statistically significant (p<0.05). In non diabetic stress hyperglycemic patients, heart failure was 78.31% patients and in non diabetic normo-glycemic patients, it was 21.6%. It was statistically significant (p<0.01). Echocardiography showed that patients with non diabetic Stress hyper-glycaemia had mean ejection fraction (LVEF) was 44.01±4.93 and patients with non diabetic normo-glycaemia had mean ejection fraction (LVEF) was 47.70±5.71. It was statistically significant (p<0.01). In this study, in non diabetic Stress hyperglycaemic patients, cardiogenic shock was 16.1% and in non diabetic normo-glycemic patients, it was 3.7%. It was statistically significant (p<0.05). Mean duration of hospital stay, in non diabetic Stress hyperglycaemic patients was 5.07±0.566 and in non diabetic normo-glycemic patients, it was 3.52±0.850. It was statistically significant (p<0.001). In conclusion, the incidence of death, heart failure, cardiogenic shock and hospital stay were higher in non diabetic Stress hyperglycaemic patients than non diabetic normo-glycemic patients who admitted with first attack of acute ST elevated myocardial infarction.

Redefinition of site percolation in light of entropy and the second law of thermodynamics

In this article, we revisit random site and bond percolation in a square lattice, focusing primarily on the behavior of entropy and the order parameter. In the case of traditional site percolation, we find that both the quantities are zero at p=0, revealing that the system is in the perfectly ordered and in the disordered state at the same time. Moreover, we find that entropy with 1-p, which is the equivalent counterpart of temperature, first increases and then decreases again, but we know that entropy with temperature cannot decrease. However, bond percolation does not suffer from either of these two problems. To overcome this, we propose an alternative definition for site percolation where we occupy sites to connect bonds and we measure cluster size by the number of bonds connected by occupied sites. This resolves all the problems without affecting any of the existing known results.

Study of Diameter of Lymphoid Follicle of Vermiform Appendix in Bangladeshi People of Different Age and Sex

A cross sectional descriptive study was performed on 40 postmortem vermiform appendix (male 24 and female 16) to find out the diameter of lymphoid follicle of vermiform appendix of Bangladeshi people. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique and were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). For this purpose, about 3mm long of whole thickness transverse section was taken from the middle of the vermiform appendix and thus the permanent slides were made for microscopic examination. To measure the diameter of the lymphoid follicle two measurements were taken. One was taken at the maximum diameter and another was perpendicular to it by ocular micrometer. Diameter of one largest and one smallest lymphoid follicles were measured and find out the mean diameter of lymphoid follicle between them. Diameter of lymphoid follicle = (Maximum transverse diameter + perpendicular diameter) /2. All data were recorded in the predesigned data sheet, analyzed by SPSS program (version 21, 2012) and compared with the findings of other national and international studies and standard text books. It was observed that diameter of lymphoid follicle of vermiform appendix gradually decreased as age advanced. The mean±SD diameter of lymphoid follicle was 580.31±37.07, 545.58±38.37, 485.68±40.20 and 428.12±68.41μm in Group A, B, C and D respectively. Statistical analysis shows that the mean differences of diameter of lymphoid follicle between A&B, C&D were statistically non significant at p= or >0.05 level, difference between Group B&C was statistically moderately significant at p<0.01 level and differences between Group A&C, B&D, A&D were statistically highly significant at p<0.001 level. Mean diameter of lymphoid follicle of vermiform appendix in male was higher (584.30±12.65μm in Group A, 549.42±38.36μm in Group B, 487.38±39.91μm in Group C, 430.68±70.30μm in Group D) than in female (576.31±53.77μm in Group A, 536.61±45.14μm in Group B, 483.14±46.68μm in Group C, 424.28±75.95μm in Group D) but mean difference between sexes in the different groups was statistically non significant at p=or >0.05 level. The present study will help to increase the information pool on the diameter of lymphoid follicle of vermiform appendix of Bangladeshi people.

Prevalence and Predictors of Depression among Patients with Type 2 Diabetes: A Multicenter Cross-sectional Study from Bangladesh

Depression is a common comorbidity of type 2 diabetes mellitus (T2DM) which adversely affects diabetes management and outcome. Identifying and treating comorbid depression may improve diabetes care. This cross-sectional study was conducted in several tertiary hospitals throughout Bangladesh from July 2017 to April 2018. Nine hundred (900) adult patients with T2DM aging ≥25 years having diabetes for at least 6 months and equal numbers of non-diabetic otherwise healthy controls were recruited from the outpatient departments of these centers. Depression was assessed in all consenting patients and controls by administering the Bangla (local language) version of the PRIME-MD Patient Health Questionnaire (PHQ-9); participants obtaining a score of 5 or more were labeled to have depression. Depression was present in 60.3% of T2DM patients and in 29.4% of controls. Statistically significant difference was found in age, marital status, occupation, body mass index (BMI), waist circumference, systolic blood pressure (BP), diastolic BP and PHQ-9 score between diabetic and non-diabetic subjects (<0.001). T2DM subjects had 4.71-fold higher odds of depression in comparison to the controls (95% CI: 3.76-5.90; p<0.001). Age ≥50 years, unmarried status, years of schooling ≤10 years, underweight, abdominal obesity, and hypertension appeared to be the significant predictors of depression in the study subjects. In T2DM subjects, diabetes in the family members, the presence of other comorbidities, diabetic complications, diabetes duration >5 years, insulin use, using insulin syringe for injection, albuminuria and CKD were the important predictors of depression. Our study found higher prevalence and risk of depression in T2DM patients than their non-diabetic counterparts. T2DM patients should be screened for depression in order to achieve and maintain the treatment goals.

Outcome of Transcanalicular Endolaser and External Dacryocystorhinostomy in Chronic Dacryocystitis

Nasolacrimal duct obstruction due to chronic dacryocystitis is the most common cause of epiphora. Dacryocystorhinostomy (DCR) is the treatment of choice for chronic dacryocystitis. This can be carried out by external, endoscopic and endolaser surgical approach. Though external DCR is still a gold standard and most popular method, the latest procedure of less traumatic DCR is transcanalicular approach. The study was done to evaluate the outcome of Transcanalicular Endolaser DCR regarding epiphora and surgery related complications by measuring anatomical success rate (patency assessed by irrigation), functional success rate (symptom free) and complication rate and to compare with External DCR (Ext-DCR). This prospective interventional study was conducted from October 2011 to September 2012 in Ophthalmology department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Total 62 patients included in the study as per inclusion and exclusion criteria of them 31 for TCEL-DCR and 31 for Ext-DCR. But during follow-up one patient was dropped from each group and finally outcome of 30 patients analyzed in each group. Mean age of the patients TCEL-DCR was 38.3±11.54 and of Ext-DCR was 38.4±14.01. In both groups females were the most sufferer (female: male = 1.5: 1). Functional and anatomical success rate of TCEL-DCR showed 93.3% and 83.3% after 3 months; 83.3% and 76.7% after 6 months respectively. Statistically non-significant difference was observed about success rate in comparison between groups. Per-operative complications were pain excessive bleeding. In TCEL-DCR pain complained 13.3% and excessive bleeding occurred in 3.3%. Where as in Ext-DCR pain complained 16.7% and excessive bleeding occurred in 20%; difference was statistically significant (p=0.001). Post-operative complications were bleeding and scar formation. Bleeding occurred in TCEL-DCR 6.67% and in Ext-DCR 10%. So, TCEL-DCR could be an alternative option for the treatment of chronic dacryocystitis especially for those patients who are conscious about scar formation and afraid about Ext-DCR technique.

Prevalence of clinical and subclinical caprine mastitis of northern region in Bangladesh

Mastitis is a multifactorial and infectious disease of the udder of dairy animals. Infected animals suffer from pain and fever and causing damage in udder and changes in milk. The aim of this work was to determine the prevalence of clinical and sub-clinical caprine mastitis associated with bacterial pathogens during the period from January to June, 2017. A total of 120 lactating goats were randomly selected from different villages of Dinajpur district and 240 milk samples from each udder half were aseptically collected. The udders were examined and screened for the evidence of clinical and subclinical mastitis by clinical examination of udders and examining milk samples. Subclinical mastitis was detected by California Mastitis Test (CMT). Milk samples of all clinical and subclinical mastitis goats were cultured in/on bacteriological media for isolation and characterization of responsible bacterial pathogens. The overall prevalence of clinical and subclinical mastitis in goats was found to be 11.67% and 38.75%, respectively. Bacteriological examination of mastitic milk samples of caprine revealed Staphylococcus spp. (32.5%) as the major pathogen followed by Escherichia coli (22.5%), Pseudomonas spp. (12.5%), Klebsiella spp. (12.5%) and Bacillus spp. (5%). Results of this study indicated that about 50% of caprine udder were infected with mastitis (38.75%), which may render lowering milk production and mortality of goats and kids. It needs to screen milk sample of lactating goats by CMT, identify mastitic goats with infected bacteria, evaluate antibiotic sensitivity and design control strategy accordingly.Progressive Agriculture 29 (2): 127-138, 2018

Clinicopathological Study of Enterocutaneous Fistula in Mymensingh Medical College Hospital

Enterocutaneous fistulae are a major catastrophe to the patients and surgeons and it still has high incidence of morbidity and mortality and their management remains a big challenge. Enterocutaneous fistula presents the surgeon with challenges of metabolic disorders and extensive sepsis. Total management of an intestinal fistula requires skill in nutritional support, stoma therapy, elimination of sepsis, well timed and well carried out surgery. Postoperative enterocutaneous fistulae account for approximately 80% of enterocutaneous fistulae. The majority of the intestinal fistula (75-85%) is iatrogenic occurring in the postoperative period following anastomotic dehiscence. They arise following emergency abdominal surgery for intestinal obstruction, inflammatory bowel disease or cancers. Protein calorie malnutrition alters the patients immune response, inflammatory reactions and tissue regenerations, all of which are essential for wound repair. The present study is an effort to highlight the incidence of enterocutaneous fistula after emergency and elective resection and anastomosis of gut with discussion over recent trends and developments in its management and compare with other studies. Objectives of the study are to determine the various clinicopathological features and management protocol of enterocutaneous fistula. There are recent advances in nutritional support. This descriptive type of cross-sectional study was carried out in the Department of Surgery, Mymensingh Medical College and Hospital, Mymensingh, Bangladesh from October 2010 to September 2011. Total 42 cases of enterocutaneous fistulae were selected purposively. Enterocutaneous fistulae are more common in patients of low economic condition. Enterocutaneous fistulae are more common after emergency abdominal surgery. Spontaneous closure occurred in 17(40.48%) cases and surgery needed in 25(59.52%) cases. Of them 20(80.00%) were healed and 5(20.00%) were expired. In spite of improvement in the management protocol of enterocutaneous fistula, there is still high unacceptable morbidity and mortality rate. Total parenteral nutrition (TPN) is not available and very costly, and health care facilities are also limited in our country. Patients with enterocutaneous fistula require fluid, electrolytes and nutritional support. Anaemia, dehydration, electrolytes imbalance should be corrected prior to abdominal surgery if possible. Surgical treatment for enterocutaneous fistula should be performed only after failure of conservative treatment of more than 12 weeks.

Comparison of Outcome of Eclamptic Patient Following Vaginal Delivery versus Caeserian Delivery by Spinal Anaesthesia

Eclampsia is a common problem in pregnancy in Bangladesh. It is a severe form of preeclampsia which affects 5 to 7% of pregnancies is a significant cause of maternal & neonatal morbidity & mortality. Pre-eclampsia when complicated with generalized tonic-clonic convulsions and/or coma is called eclampsia. The term eclampsia is derived from a Greek word, meaning "like a flash of lightening". It may occur quite abruptly, without any warning manifestations. Eclampsia is a major cause of maternal mortality & morbidity as well as foetal loss worldwide, particularly in the third world. Appropriate measures & effective treatment of eclamptic patient in proper time reduce maternal mortality & morbidity. The mainstay of treatment of eclampsia is delivery of the foetus. Two methods are usually applied for delivery of foetus in eclampsia i.e. vaginal delivery & caesarean delivery. This study was done in the department of Gynae & Obs and department of Anaesthesiology, Mymensingh Medical College Hospital from 1st January 2016 to 30th June 2016 to observe the incidence, complications (morbidity) & mortality of eclamptic patients & which method (vaginal delivery versus caesarean delivery by spinal anaesthesia) is safe, better for the eclamptic patients as well as foetal mortality. Successful vaginal delivery is dependant on complex interactions of three variables (3 P) that is power (uterine contraction), passenger (foetus) & passage (birth canal) but power is less effective in eclamptic patient than normal partuents. Vaginal delivery requires prolong times compared with cesarean delivery. Anaesthetic technique is also an important factor for maternal mortality & morbidity of caesarean delivery. Spinal anaesthesia is widely regarded as a reasonable anaesthetic option for caesarean delivery in eclamptic patients. Currently the safety of spinal anaesthesia is well established and it can provide better obstetrical outcome when chosen properly. In this observation caesarean delivery by spinal anesthesia is safer, less complications, less maternal & neonatal mortality than vaginal delivery in eclamptic patients.

Immune Response against Hepatitis B virus after Pentavalent Vaccination in Children

This study was done to know the real status of immune response to Hepatitis B vaccine among the pentavalent vaccinated children as per EPI schedule of Bangladesh. It was prospective observational study done in the EPI corner of Paediatric OPD of Dhaka National Medical College & Hospital (DNMCH), Dhaka from July 2015 to July 2016. Sixty (60) children ranging from 9 months to 2 years of age, who received pentavalent vaccination (Hepatitis B + DPT + Hib) according to EPI schedule, were included. The testing for anti-HBs titres were conducted in the Department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Out of 60 children, 9(15%) had anti-HBs titres <10 IU/L (non-protected) while 51(85%) had anti-HBs titres >10 IU/L (protected). Twenty seven (27) were male and of them 21(77.8%) protective and 6(22.2%) non-protective. Thirty three (33) were female, out of them 30(90.9%) protective while 3(9.1%) non-protective. The difference was not significant between male and female (p=0.156). Fifty (50) children received vaccination by EPI (Government) (pentavalent) out of which 9(18%) non-protective and 41(82%) protective level. However, 10 children received privately Hepatitis B vaccination of which all developed protective level. The difference was not significant between Government (EPI) and privately vaccine (p=0.145). Most of the children showed positive immune response after pentavalent vaccination.

Rupture of the Pregnant Uterus in Eastern Libya

One hundred and forty-six cases of rupture of the uterus during labour are reported and obstetric practice is described in Eastern Libya, where these disasters took place. The incidence and the causes of uterine rupture in Libya differ greatly from those in developed countries; high multiparity is a frequent cause. Hysterectomy is very often the best treatment. More than three-quarters of the children were lost, but 92% of the mothers were saved.

Management of Infected Sebaceous Cyst by Suture Closure: A New Approach

Incision and drainage is the management plan of any infected sebaceous cyst from old age. But in infected sebaceous cyst, we can treat it in a simple way.Under local or general anesthesia the infected tissue is excised along with a rim of healthy tissue and then closed by Prolene in the same sitting. Usually stitches are removed on 21st day in the back and 14th day in the limb. This cross sectional observational study was carried out in the Department of Surgery of 250 Bed District Hospital, Kishoreganj and local clinics of Kishoreganj, Bangladesh from January 2012 to March 2015. One hundred (100) cases were selected with clinical diagnosis of infected sebaceous cyst and the procedure was carefully explained to every patients. The overall results were analyzed and it was revealed that with this method patients got quick recovery and no need for frequent dressing which prevents cross infection. It is cost effective and saves time also.

Modified Blatchford Score for Risk Stratification in Adult Patient with Nonvariceal Upper Gastrointestinal Haemorrhage and Their Short Term Hospital Outcome

Upper gastrointestinal hemorrhage (UGIH) is one of the most common and life-threatening gastrointestinal emergency. There are several risk scores for risk stratification in UGIB patients. The Modified Blatchford score, which relies only on clinical and laboratory parameters, is practical in the emergency setting The Modified Blatchford scoring system also known as Glasgow Blatchford Scoring (GBS) have been developed to stratify risk of non variceal upper gastrointestinal hemorrhage or need of medical or surgical intervention, endoscopic therapy. Objective of this study is to see risk stratification by The Modified Blatchford score and short term hospital outcome in non variceal upper GI hemorrhage patients. The observational study was carried out over a period of 6 months from October, 2014 to March, 2015 in Department of Department of Medicine, Gastroenterology and Surgery Mymensingh Medical College Hospital, Mymensingh. A total of 120 patients with non variceal UGIH were taken for the study during study period. Categorical variables were reported as percentage and Means and proportions were carried out using the Chi-square test (X2-test) of different variables by SPSS software version-18.0. Patients related variables age, sex; and main outcome variables the Modified Blatchford scoring system, Risk stratification, and short term hospital outcome were observed. Age frequency among total cases were 66(55%) <60 years, 50(41.67%) from 60-79 years and 4(3.3%) 80 years or above and sex distribution were 84(70%) were male and 36(30%) were female patients. Blatchford score of patients 1(0.83%) had score 0, 1(0.83%) had score 1, 2(1.67%) had score 2, 2(1.67%) had score 3, 2(1.67%) had score 4, 3(2.5%) had score 5, 12(10%) had score 6; 15(12.5%) had score 7, 16(13.33%) had score 8, 17(14.17%) had score 9, 16(13.33%) had score 10, 15(12.5%) had score 11, 10(8.33%) had score 12, 4(3.33% ) had score 13, 1(0.83%) had score 14, 2(1.67%) had score 15 and 1(0.83%) had score 16. Risk stratification showed 54(45%) had low risk (Mean GBS score 6.19±1.79), 66(55%) had high risk (Mean GBS score 11.03±1.83) Outcome of the patients were observed that 1(0.83%) died, 54(45%) was discharged without any medical or surgical intervention, and 65(54.17%) patients' needs medical or surgical intervention such as blood transfusion and endoscopy. Among total 120 patients with upper GI hemorrhage I have found that GBS score of three or less than three is predictive of low risk of adverse outcomes and can be discharged without any intervention.

Comparative Efficacy of Local Steroid and Therapeutic Ultrasound for Quicker Functional Improvement in Tennis Elbow

Lateral epicondylitis or Tennis elbow is very common repetitive stress injury or cumulative trauma disorder among active professionals and tennis players. Local steroid injection can provide quick functional improvement as sought by most of the patients. Therapeutic ultrasound and eccentric exercises can also improve the function. This study was carried out to see the comparative efficacy of these two modalities of treatments in terms of quicker functional improvement and this randomized interventional clinical trial was carried out in a private rehabilitation hospital in Dhaka. Patients attended the authors private chamber from January 2013 to December 2013 with clinical diagnosis of tennis elbow were included. Eighty adult patients diagnosed as lateral epicondylitis or tennis elbow were randomly divided into two groups. Group A received local steroid injection (triamcinolone acetate) and group B received therapeutic ultrasound for two weeks. Both the groups received eccentric exercises and advised to avoid provocative activities like twisting and lifting activities. Pain, tenderness and functional improvements were measured in traditional methods like visual analogue scale (VAS) and tenderness grade 0 to 4. Data were analyzed by SPSS. Most of the patients were female. None of them were tennis player. Younger housewives were common sufferer. Almost all patients in group A had very little or no pain or tenderness and no difficulty in lifting object at one week and two weeks. VAS was 13.62±6.503 and 4.15±5.517 respectively. Group B patients had mild improvement of pain and function at one week and moderate improvement at two weeks. VAS was 52.57±7.80 and 25.57±5.392 respectively. Similarly tenderness' were markedly improved in Group A at one and two weeks. They were 0.68±0.616 and 0.02±0.405 respectively for Group A and 1.60±0.553 and 1.14±0.335 respectively for Group B. Results were statistically significant in both groups at the end of two weeks. Local corticosteroid injections at extensor origin in tennis elbow patients are found to have better relief of pain and tenderness and quicker functional improvement than therapeutic ultrasound treatment. None of the patients were followed up for long term efficacy in either group.

Arsenic bio-accessibility and bioaccumulation in aged pesticide contaminated soils: A multiline investigation to understand environmental risk

Bio-accessibility and bioavailability of arsenic (As) in historically As-contaminated soils (cattle tick pesticide), and pristine soils were assessed using 3 different approaches. These approaches included human bio-accessibility using an extraction test replicating gastric conditions (in vitro physiologically-based extraction test); an operationally defined bioaccessibility extraction test - 1.0M HCl extraction; and a live organism bioaccumulation test using earthworms. A sequential extraction procedure revealed the soil As-pool that controls bio-accessibility and bioaccumulation of As. Findings show that As is strongly bound to historically contaminated soil with a lower degree of As bio-accessibility (<15%) and bioaccumulation (<9%) compared with freshly contaminated soil. Key to these lower degrees of bio-accessibility and bioaccumulation is the greater fraction of As associated with crystalline Fe/Al oxy-hydroxide and residual phases. The high bio-accessibility and bioaccumulation of freshly sorbed As in pristine soils were from the exchangeable and specifically sorbed As fractions. Arsenic bioaccumulation in earthworms correlates strongly with both the human bio-accessible, and the operationally defined bioavailable fractions. Hence, results suggest that indirect As bioavailability measures, such as accumulation by earthworm, can be used as complementary lines of evidence to reinforce site-wide trends in the bio-accessibility using in vitro physiologically-based extractions and/or operationally defined extraction test. Such detailed knowledge is useful for successful reclamation and management of the As contaminated soils.

Large adrenal leiomyoma presented as adrenal incidentaloma in an AIDS patient: A rare entity

The literature on adrenal gland tumour in HIV-infected patients is scarce. We report a 46-year-old Malay man with HIV and Hepatitis C infection presenting with a large nonfunctioning adrenal tumour. Computed tomography showed a large right adrenal tumour with heterogeneous enhancement and central necrosis. A high index of suspicion of a malignant tumour or pheochromocytoma led us to surgical removal of the adrenal gland. In this case report, we highlight important features to look for during pre-op evaluation of a large adrenal mass. Appropriate action should be taken when there is a suspicion of a pheochromocytoma or malignancy.

Arsenic solid-phase speciation and reversible binding in long-term contaminated soils

Historic arsenic contamination of soils occurs throughout the world from mining, industrial and agricultural activities. In Australia, the control of cattle ticks using arsenicals from the late 19th to mid 20th century has led to some 1600 contaminated sites in northern New South Wales. The effect of aging in As-mobility in two dip-site soil types, ferralitic and sandy soils, are investigated utilizing isotopic exchange techniques, and synchrotron X-ray adsorption spectroscopy (XAS). Findings show that historic soil arsenic is highly bound to the soils with >90% irreversibly bound. However, freshly added As (either added to historically loaded soils or pristine soils) has a significantly higher degree of As-accessibility. XAS data indicates that historic soil arsenic is dominated as Ca- (svenekite, & weilite), Al-(mansfieldite), and Fe- (scorodite) like mineral precipitates, whereas freshly added As is dominated by mineral adsorption surfaces, particularly the iron oxy-hydroxides (goethite and hematite), but also gibbsite and kaolin surfaces. SEM data further confirmed the presence of scorodite and mansfieldite formation in the historic contaminated soils. These data suggest that aging of historic soil-As has allowed neoformational mineral recrystallisation from surface sorption processes, which greatly reduces As-mobility and accessibility.

Processable dodecylbenzene sulfonic acid (DBSA) doped poly(N-vinyl carbazole)-poly(pyrrole) for optoelectronic applications

A soluble poly (n-vinyl carbazole)–polypyrrole (PNVC–Ppy) copolymer was prepared through oxidative chemical polymerization wherein dodecyl benzene sulfonic acid (DBSA) was used as a dopant to facilitate polymer-organic solvent interaction and ammonium persulfate (APS) was used as an oxidant. Compared with undoped PNVC–Ppy, the DBSA-doped PNVC–Ppy copolymer showed higher solubility in some selected organic solvents. The composition and structural characteristics of the DBSA-doped PNVC–Ppy were determined by Fourier transform infrared, ultraviolet–visible, and X-ray diffraction spectroscopic methods. Field emission scanning electron microscopic method was employed to observe the morphology of the DBSA-doped PNVC–Ppy copolymer. The electrical conductivity of the DBSA-doped PNVC–Ppy copolymer was measured at room temperature. The conductivity increased with increasing concentration of APS oxidant, and the highest conductivity was recorded at 0.004 mol/dm³ APS at a polymerization temperature of −5 °C. The increased conductivity can be explained by the extended half-life of pyrrole free radical at a lower temperature and a gradual increase in chain length over a prolonged time due to the slow addition of APS. Furthermore, the obtained soluble copolymer exhibits unique optical and thermal properties different from those of PNVC and Ppy.

Klippel Trenaunay Syndrome: A Case Report

Klippel Trenaunay syndrome refers to a rare congenital anomaly which is characterized by capillary malformation, venous malformation and sometimes lymphatic malformation associated with overgrowth of a limb, with soft tissue hypertrophy and/or bony hypertrophy. The anomaly, if present, is present at birth and usually involves the lower limbs as well as portion of trunk, face, uppper limb or head. Our reporting case is a preterm male neonate having port wine stain, varicose veins and excessive growth of soft tissue of left lower limb clinically consistent with Klippel Trenaunay Syndrome.

Assessing the Rehabilitation of Achilles Tendon Ruptures using Modified Teuffer and Lindholm Technique

The aim of this study is to assess the optimum rehabilitation and the functional outcome of open repaired Achilles tendon ruptures. This study was conducted for the 18 consecutive patients of complete ruptures at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from 2012 to 2013. Two groups were considered during 6 to 18 months post-operative observation and each group consist 9 patients. In the Group I, modified Teuffer's and in Group II, Lindholm operative methods were employed for the open repair of Achille tendon. The post operative outcomes were assessed for both of the groups through the modified Thermann's scores. In this study the patients median age was seen 39 years with 72.2% male and 27.8% female. The Thompson test was found positive in pre-operative and negative in post-operative outcome. The results shown that Achilles tendon ruptures occurred in 4 to 6cm rupture site, where the rupture side was 61.1% left and 38.9% right. The subjective overall assessment of total Thermann's scores were found very good (91 to 96) in 4 cases and (90 to 98) in 3 cases for Group I and Group II, respectively. Both of the operative techniques were found accountable results for rehabilitation. Therefore, based on the further statistical evidence of higher correlations and errors it may be concluded that Achilles tendon ruptures can be treated by modified Teuffer's or Lindholm technique.

Rice Vision for Bangladesh: 2050 and Beyond

CORRECTION: Due to a number of formatting and layout issues, the PDF of this paper was replaced on 10th October 2016.Combined efforts of farmers, rice scientists, extension personnel and Government of Bangladesh have yielded clean rice growth rate of 0.34 million ton (MT) year-1 during 2009-10 to 2013-14 in the country. In 2014-15, the country acquired a rice surplus of about 2 MT. However, maintaining the current surplus of rice in the coming decades is a great challenge. Authentic estimation of future rice requirement and future resource availability would guide to way forward. This paper presents rice vision for Bangladesh leading to 2050 and beyond. In this study, secondary data from different government-owned statistics and research institutes were collected, analyzed and synthesized to develop models and/or model parameters to generate outputs such as future population, rice production and rice requirement. Population of Bangladesh will reach 215.4 million in 2050, when 44.6 MT of clean rice will be required. With the pace of rice-production-increase in the last five years, production can reach 47.2 MT, having a surplus of 2.6 MT in 2050. The study sets 2.6 MT as the target for clean rice surplus every year leading to 2050 and beyond. Several hurdles, such as increasing population, decreasing resources and increasing climate vulnerability, can hinder achieving the target. Three major interventions?accelerating genetic gain, minimizing yield gap and curtailing adoption lag?are proposed to break the barriers to achieve the target. Major challenges to implement the interventions include shrinking net cropped area, decreasing availability of irrigation water and increasing pressure on soil fertility. Smart technology such as, location specific variety, profitable cropping sequences, innovative cultural management, and mechanization coupled with smart dissemination using multiple means would ease production barriers. We recommend a number of measures, such as, guaranteeing a minimum cropped area, accelerating the rate of genetic gain in varietal development and intensifying collaboration among the stakeholders to reduce adoption lag of newly released promising rice varieties, to achieve the rice vision of Bangladesh leading to 2050 and beyond.Bangladesh Rice j. 2015, 19(2): 1-18

Analgesic and antidepressant activities of Brassica rapa subspecies chinensis (L.) Hanelt on Swiss-albino mice model

Bangladesh being a subtropical country provides varieties of herbs and vegetables. Brassica is a broad genus available in Bangladesh and it encompasses a lot of nutritive herbs. Among these, Brassica rapa subspecies chinensis (L.) Hanelt (Family-Brassicaceae) is popular in many parts of the world. In the quest of medicinal property, this plant was investigated here for observing analgesic and antidepressant activities in Swiss-albino mice model. The herb was extracted well with methanol and then assayed by acetic acid-induced writhing and tail immersion methods for analgesic action. Besides, thiopental sodium induced sleeping time test, tail suspension test and forced swim test were conducted for the evaluation of its antidepressant activity. The plant extract was orally administered to the mice at 200 and 400 mg/kg body weight and it exhibited significant analgesic and antidepressant activities in compare to the controlled groups. This is the first time comprehensive report for analgesic and antidepressant activities of this plant.

Mesoblastic Nephroma in a 22 Years Old Woman

Mesoblastic nephroma is an uncommon renal tumor of infancy and rarely occurs in adults. We report a case of mesoblastic nephroma in adult. A 22-year-old woman, who presented with left flank pain, was found to have a left renal mass by abdominal ultrasonography. Computed tomography revealed a heterogeneous tumor. Left radical nephrectomy was performed. The tumor was a creamy white solid mass. Microscopically, the tumor was composed of spindle cell proliferation. Atypia and mitoses were not identified. Among the tumor cells, there were tubular arranged epithelial elements. The patient was free of recurrence 18 months postoperatively. Mesoblastic nephroma is classified as a benign tumor but recurrence and malignant transformation of this tumor have been reported, so regular postoperative follow up is required.

Maternal body mass index and risk of birth and maternal health outcomes in low- and middle-income countries: a systematic review and meta-analysis

We conducted a systematic review and meta-analysis of population-based cohort studies of maternal body mass index (BMI) and risk of adverse birth and health outcomes in low- and middle-income countries. PubMed, Embase, CINAHL and the British Nursing Index were searched from inception to February 2014. Forty-two studies were included. Our study found that maternal underweight was significantly associated with higher risk of preterm birth (odds ratio [OR], 1.13; 95% confidence interval [CI], 1.01-1.27), low birthweight (OR, 1.66; 95% CI, 1.50-1.84) and small for gestational age (OR, 1.85; 95% CI, 1.69-2.02). Compared with mothers with normal BMI, overweight or obese mothers were at increased odds of gestational diabetes, pregnancy-induced hypertension, pre-eclampsia, caesarean delivery and post-partum haemorrhage. The population-attributable risk (PAR) indicated that if women were entirely unexposed to overweight or obesity during the pre-pregnancy or early pregnancy period, 14% to 35% fewer women would develop gestational diabetes, pre-eclampsia or pregnancy-induced hypertension in Brazil, China, India, Iran or Thailand. The highest PAR of low birthweight attributable to maternal underweight was found in Iran (20%), followed by India (18%), Thailand (10%) and China (8%). Treatment and prevention of maternal underweight, overweight or obesity may help reduce the burden on maternal and child health in developing countries.

Improving litter size by boar spermatozoa: application of combined H33258/CTC staining in field trial with artificial insemination

Conventional semen analysis offers basic information on infertility; however, its clinical value in predicting fertility status is unclear. To establish an accurate diagnosis of male fertility, semen analysis under capacitation condition is necessary because only capacitated spermatozoa are capable of fertilizing oocytes. The objective of this study was to verify male fertility based on conventional semen analysis before and after capacitation, including the assessment of motility (%), motion kinematics, and capacitation status of spermatozoa. A computer-assisted sperm analysis system and chlortetracycline staining were applied to evaluate the motility parameters and capacitation status, respectively. To enable efficacy of the two methods for predicting fertility, correlation analysis was performed with the historic litter size. Our results showed that sperm motility (%), motion kinematics, and their variations before and after capacitation represented a statistical non-significant correlation with litter size. Litter size showed significant correlation with acrosome reaction (AR) after capacitation (r = 0.375), as well as differences (Δ) in AR (r = 0.333) and capacitated (B) pattern (r = -0.447) before and after capacitation. The overall accuracy of the assay for predicting litter sizes using the AR and differences (Δ) in the AR and B pattern was 70%. On the basis of these results, we propose that capacitation status of spermatozoa is a more reliable indicator for evaluating male fertility status compared to motility parameters. Therefore, we suggest that analysis of capacitation status in company with conventional semen analysis may accept to evaluate more accurate diagnosis or prognosis of male fertility.

Genetic testing for spinocerebellar ataxias in patients diagnosed as Parkinson's disease in Bangladesh

This study was conducted to find out Spinocerebellar Ataxias (SCA) by genetic analysis from those patients presenting with Parkinsonism in the Neurology department of Mymensingh Medical College Hospital, Bangladesh. A sample of about 5ml blood was collected by venipuncture in EDTA tube after having informed consent from each patients and healthy individual, with due Institutional Ethical committee approval for genetic study of 7 healthy people and 9 patients. The neurological disorder along with a complete physical and/or psychological, as well as family history and demographic data was recorded with a prescribed questionnaire by the neurologists of Mymensingh Medical College Hospital. Extraction of genomic DNA from the venous blood using Flexi Gene DNA kit (Qiagen, Japan) was performed in Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh, Bangladesh. The extracted DNA was stored, accumulated and then were sent to Division of Clinical Genetics, Department of Medical Genetics, Osaka University Medical School, Suita, Osaka 565 0871, Japan for PCR and further analysis. PCR amplification of the CAG repeat was performed for the SCA1, SCA2, SCA3, SCA6 loci using primers SCA1N-F1 and SCA1N-R1, SCA2-F1 and SCA2-R1, MJDF1 and MJDR1, SCA6-F1 and SCA6-R1, respectively. SCA1 PCR of both healthy individual and suspected Parkinsons Disease (PD) patients DNA was found 250 bp (no. of CAG repeats=36). SCA2 PCR products reveal the DNA products of about 150 bp (no. of CAG repeats=23) except one patient that was suspected and it was sequenced and revealed 175bp (no. of CAG repeats=30). SCA3 PCR product size of both healthy individual and patient DNA was within 250 (no. of CAG repeats=11) to 300 bp (no. of CAG repeats=28) except one patient which was about 320 bp and its CAG repeats was about 34. SCA6 PCR product size of both healthy individual and patient DNA was about 150 bp (no. of CAG repeats=16).

Sodium nitroprusside suppresses male fertility in vitro

Sodium nitroprusside is a nitric oxide donor involved in the regulation of the motility, hyperactivation, capacitation, and acrosome reaction (AR) of spermatozoa. However, the molecular mechanism underlying this regulation has not yet been elucidated. Therefore, this study was designed to evaluate the molecular basis for the effects of sodium nitroprusside on different processes in spermatozoa and its consequences on subsequent oocyte fertilization and embryo development. In this in vitro study, mouse spermatozoa were incubated with various concentrations of sodium nitroprusside (1, 10, and 100 μM) for 90 min. Our results showed that sodium nitroprusside inhibited sperm motility and motion kinematics in a dose-dependent manner by significantly enhancing intracellular iron and reactive oxygen species (ROS), and decreasing Ca(2+), and adenosine triphosphate levels in spermatozoa. Moreover, short-term exposure of spermatozoa to sodium nitroprusside increased the tyrosine phosphorylation of sperm proteins involved in PKA-dependent regulation of intracellular calcium levels, which induced a robust AR. Finally, sodium nitroprusside significantly decreased the rates of fertilization and blastocyst formation during embryo development. Based on these results, we propose that sodium nitroprusside increases ROS production and precocious AR may alter overall sperm physiology, leading to poor fertilization and compromised embryonic development.

Defending the fort: a role for defensin-2 in limiting Rickettsia montanensis infection of Dermacentor variabilis

The importance of tick defensins is evidenced by their expression in a wide variety of tick tissues and prevalence across many tick genera. To date, the functional and biological significance of defensin-2 as a rickettsiastatic or rickettsiacidal antimicrobial peptide has not been addressed. In a previous study, defensin-2 transcription was shown to increase in Dermacentor variabilis ticks challenged with Rickettsia montanensis. In the present study, the hypothesis that defensin-2 is functional as a rickettsiastatic and/or rickettsiacidal antimicrobial peptide is tested. We show that defensin-2 plays a role in reducing burden after acquisition of Rickettsia montanensis through capillary feeding. Moreover, defensin-2 is shown to associate with R. montanensis in vitro and in vivo, causing cytoplasmic leakiness.

Comparative efficacy of pregabalin and therapeutic ultrasound versus therapeutic ultrasound alone on patients with post stroke shoulder pain

The study was designed to compare the efficacy of pregabalin, an anticonvulsant on pain behavior of stroke patients with shoulder pain in a comparative study with ultrasound therapy and ultimately to recommend a better treatment option to improve pain and function in post stroke shoulder pain. This study was carried out in a private neurology Hospital in Dhaka during January to December 2010. Data were collected from 70 post stroke patients with shoulder pain and were divided into two groups. The patients in Group A were treated with pregabalin 100mg twice daily along with therapeutic ultrasound 10 minutes daily and group B were treated with therapeutic ultrasound alone for the same dose and duration. Pain free range of motion exercise was given to both groups as the therapeutic exercise. Pain parameters in the form of VAS were measured at one and two weeks and were compared. Seventy one percent of the patients were male with 80% were above 60 years old. Pain scoring in VAS of 100 was 21.32±6.01 in group A and 41±4.58 in groups B at the end of two weeks assuming the pretreatment VAS of all patients as 100. Marked improvement in shoulder pain were observed in both groups and Group A had better improvement in pain than group B. Therapeutic ultrasound when given with pregabalin found to have added benefit over therapeutic ultrasound alone in post stroke shoulder pain. Differences were statistically significant.

A Cyclic Voltammetric Study of the Redox Reaction of Cu(II) in Presence of Ascorbic Acid in Different pH Media

The electrochemical redox behavior of Cu(II), and Cu(II) in presence of ascorbic acid has been investigated at glassy carbon electrode (GCE) in aqueous phosphate buffer solution (PBS) at various pH. In the studied pH range the voltammogram consists of a cathodic and an anodic peak. Cu(II) follows one step two-electron transfer electrochemical redox reaction. The intensities of both cathodic and anodic peak current increase with increasing scan rate that are consistent with Randles-Sevcik equation. The linear behavior of peak current with the square root of scan rate indicates that the electrochemical processes are diffusion controlled. In presence of ascorbic acid both of the cathodic and anodic peak current of Cu(II) is reduced and peak positions are shifted compared to those of Cu(II) alone. These observation suggest that Cu(II) undergoes a strong interaction with ascorbic acid in the studied medium. DOI: http://dx.doi.org/10.3329/dujs.v61i2.17064 Dhaka Univ. J.
