Abstract
This cross sectional observational study was conducted in the Department of Nephrology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2009 to March 2010. Samples were collectedfrom rural area of Khalishaur union of Purbadhala upazilla in Netrakona District, 30km away from Mymensingh Town. The main objective of the study was to find out the prevalence of microalbuminuria as well as overt proteinuria in diabetes mellitus in a rural population and to observe their association with renal function. In this study 1048 adult participants of 18 to 65 years in a rural area of Netrakona were included purposively as study subjects. Among them 54% were male and 46% were female. Mean age of study subjects was 42.4±13.4 years. Prevalence of microalbuminuria among diabetic participants was 29.72% where as in non diabetic non hypertensive participants it was 6.62%. Diabetic persons 9.45% and 3.9% of non diabetic participants showed overt proteinuria by dipstick test. Prevalence of hypertension in diabetic and non diabetic participants was 45.94% and 16.52% respectively. The mean eCCr of the diabetic patients and non-microalbuminuric healthy persons was 78.4±25.4 ml/min/1.73m² and 94.67±24.8 ml/min/l.73m² respectively according to Cock Croft-Gault equation. The mean eCCr of diabetic participants with overt proteinuria was 57.44±28.33 ml/min/l.73m² but diabetic patients with microalbuminuria had better mean eCCr 80.62±21.17 ml/min/1.73m² which justifies the importance of detection of microalbuminuria for early intervention. By regression analysis it was found that degree of microalbuminuria had linear relation with renal function and random blood sugar level. Neither BMI nor duration of diabetes showed any correlation with urine microalbumin. There was no effect of sex on the prevalence of microalbuminuria in diabetes mellitus. Microalbuminuria is the first sign of renal involvement in diabetic patients which is a risk factor for overt nephropathy. Monitoring of this condition is important because early treatment of microalbuminuria can prevent or postpone overt nephropathy.

Abstract
Bacterial infections have become a global issue that requires urgent attention, particularly regarding to emergence of multidrug resistant bacteria. We developed quaternary amine-containing antimicrobial poly(bile acid)s that contain a hydrophobic core of lithocholic acid in the main-chain. Interestingly, by choosing appropriate monomers, these cationic polymers can form core-shell micelles. These polymers exhibited biocidal activity against both Gram-positive and Gram-negative bacterial species. It is demonstrated that the micelles can deliver hydrophobic antibiotics that functionally have dual antimicrobial activities. Cytotoxicity assays against HeLa cells showed dosage-dependent toxicity for polymers with longer linkers.

Abstract
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.

Abstract
Stroke is one of the leading causes of death and disability in developed as well as developing countries like Bangladesh. There is a crucial need to identify additional risk factors that are easily measurable and treatable in general population. Role of serum lipids, lipoproteins and lipoprotein related variables in the prediction of stroke is less clear. Abnormalities in plasma lipoproteins are the most firmly established and best understood risk factors for atherosclerosis and they are probable risk factors for ischaemic stroke, largely by their link to atherosclerosis. High serum apolipoprotein-B (Apo-B) levels may predict an increased risk for ischaemic stroke. Aim of the study was to evaluate the association between serum Apo-B level and acute ischaemic stroke and to measure and compare serum Apo-B level in ischaemic stroke and normal subjects. A cross-sectional comparative study was carried out in the department of Neurology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2013 to June 2015. A total number of 100 subjects within 18-70 years were considered for the study. Fifty (50) subjects with stroke (both clinically as well as CT scan of head or MRI of brain proven) were taken as the cases and 50 age and sex matched nearly healthy individuals without stroke were taken as the controls by using non-probability sampling procedure. Total cholesterol, HDL cholesterol and triglycerides were estimated by enzymatic method using Semiautoanalyser. LDL cholesterol was estimated by Friedewald formula. Apo-B was estimated by immunoturbidimetric method using Semiautoanalyser. Finally collected data were analyzed by using SPSS software Version 20. Student 't' test was used to compare the data between cases and controls. P value was set <0.05. Diagnostic validity tests were conducted to assess the diagnostic efficiency of Apo-B. Total cholesterol, LDL cholesterol and triglycerides are significantly increased in cases compared to controls. HDL-cholesterol was significantly decreased in cases compared to controls. Apo-B was significantly increased in cases compared to controls. The result was statistically significant. Apo-B may be used as predictors of ischaemic stroke components.

Abstract
Chronic kidney disease (CKD) is an international health problem affecting 5-10% of the world population. Patients with chronic kidney disease were known to have higher prevalence of changes in serum calcium, phosphate and parathyroid hormone in Western countries, but data on the impact of CKD on serum calcium, phosphate and parathyroid hormone in our country are scarce. This cross-sectional type of descriptive study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2016 to September 2016. The aim of this study is to estimate serum calcium, phosphate and parathyroid hormone levels in chronic kidney disease (CKD) patients for early recognition of abnormalities, understanding of their patho-physiological consequences & planning management strategies to prevent their progression, thus reducing the morbidity & mortality. This study shows Hypocalcemia, hyperphosphataemia and elevated serum PTH levels are noted in later CKD stages & worsen with disease progression.

Abstract
UNLABELLED OBJECTIVE: The study evaluated the effects of glucose-fructose or sucrose supplementation in glycerol-free Tris (GFT) solution on motility, viability, the level of reactive oxygen species (ROS), as well as the level of apoptosis (BAX and BCL2) and motility (SMCP)-related gene expression of dog spermatozoa. MATERIALS AND METHODS Spermatozoa (5×107 sperm/ml) were cryopreserved in GFT containing 86 mM glucose and 86 mM fructose (GF-GFT) or 100 mM sucrose (S-GFT). Progressive motility, viability, ROS (H2O2) level and mRNA gene expression of spermatozoa were evaluated 0 h, 3 h or 6 h post-thaw at 24°C. RESULTS The motility of spermatozoa cryopreserved in GF-GFT was increased throughout the post-thaw incubation time. The motility of spermatozoa cryopreserved in S-GFT was increased at 3 h of post-thaw incubation. The sperm ROS level in the GF-GFT group was inconsistent during the post-thaw incubation time; however, the ROS level in the S-GFT group was gradually increased with progression of the post-thaw incubation period. The post-thaw incubation had no substantial effect on the mRNA expression of the BAX, BCL2, and SMCP genes of spermatozoa in both the GF-GFT and S-GFT groups. CONCLUSION The supplementation of glucose and fructose improves progressive sperm motility during 6 h of post-thaw incubation while maintaining similar sperm viability. The addition of GF to GFT for cryopreservation and post-thaw incubation would yield more functional spermatozoa for future assisted reproduction practices.

Abstract
This cross sectional, descriptive and analytic study was conducted among 5-10 years aged 109 Bangladeshi children (70 male and 39 female) at different areas of Mymensingh district (Fulpur, Muktagacha, Fulbaria, Trisal and Haluaghat), Bangladesh from January 2016 to December 2016. Sample collection was done by nonrandom purposive sampling technique. Any kind of congenital and acquired foot deformity was excluded to construct standard measurement. The present anthropometric study was designed to construct data of 5 to 10 years aged Bangladeshi children regarding ball circumference, to measure its correlation with body weight and this attempt has been made out to grow interest among the researchers for future study and also to compare the data with the data of the people of other races. Weight of the subject was measured with the digital weighing machine and ball circumference was measured using flexible measuring tape. The children were asked to stand with weight distributed equally on both feet. The legs were perpendicular to the feet. The mean ball circumference of right side of 5, 6, 7, 8, 9 and 10 years aged male were 16.93±1.05cm, 17.00±0.72cm, 18.10±1.28cm, 18.33±.99cm, 19.37±1.12cm and 19.94±1.30cm respectively and those of female were 16.27±1.10cm, 16.85±0.59cm, 17.44±0.92cm, 18.02±0.82cm, 18.00±1.58cm and 19.23±1.40cm respectively. The mean ball circumference of left side of 5, 6, 7, 8, 9 and 10 years aged male were 16.86±1.05cm, 16.94±.70cm, 18.02±1.29cm, 18.26±.99cm, 19.27±1.12cm and 19.87±1.29cm respectively and those of female were 16.18±1.10cm, 16.77±0.62cm, 17.36±0.92cm, 17.98±0.87cm, 17.90±1.58cm and 19.13±1.40cm respectively. In this study on both sides, ball circumference showed non-significant positive correlation with body weight in 5 years old male and female, 6 years old male and female, 7 years old male and female, 8 years old female, 9 years old male and female and 10 years old male and female. In case of 8 years old male, it showed non-significant negative correlation with body weight.

Abstract
Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017. The patients were selected from the ENT outpatient department and from the department Radiology & Imaging of Mymensingh Medical College Hospital, Mymensingh, Bangladesh who were reported as case of sinonasal masses. Thirty three (33) patients (17 males and 16 females) with sinonasal masses were included after fulfilling exclusion & inclusion criteria which was confirmed by proper clinical examination & were subjected to MRI and histopathological examination. The age range was 11 to 85 years. The nasal cavity was the most commonly involved site with sinonasal malignancies (were 4 cases, 12.12%) followed by the maxillary sinuses (were 2 cases, 6.06%). The least commonly affected site was the frontal sinuses (was 1 case, 3.03%). Histopathological findings shows benign sinonasal tumors were present in 25 cases. The most common benign lesion was sinonasal polyposis 10 cases (30.30%), followed by inverted papilloma 6 cases (18.18%) & juvenile nasopharyngeal angiofibroma 6 cases (18.18%), adenoma 02 cases (6.06%), and one case was rhinosporidiosis (3.03%). Malignant sinonasal tumors were present in 8 cases. Most common malignant tumors were nasopharyngeal carcinoma in 4 cases (12.12%), adenoid cystic carcinoma in 3 cases (9.09%) and non-Hodgkin lymphoma was present in 01 case (3.03%). MRI report shows benign masses in 23 cases of which nasopharyngeal polyposis was 10(30.30%), inverted papilloma 6(18.18%), juvenile angiofibroma 4(12.12%), adenoma 02(6.06%) & rhinosporidiosis 1(3.03%). Among 10 malignant tumors nasopharyngeal carcinoma were 6(18.18%), adenoid cystic carcinoma 3(9.09%) & non-Hodgkin lymphoma 1(3.03%). MRI findings of malignant sinonasal masses revealed that sensitivity 87.5%, specificity 40.0%, positive predictive value (PPV) 70% & negative predictive value 66%. Statistically significant association was observed between histopathology & MRI findings, p value was 0.305. Statistically significant association was found between histopathology & MRI findings.

Abstract
Formation of nanoclusters has attracted a lot of attention in recent years because of their distinct properties from isolated atoms and bulk solids. Here, we focus on the catalytic properties of supported transition metal oxide nanoclusters, such as TaO2, with a well-defined size distribution below 10 nm. We show that their catalytic performance can be greatly enhanced by introducing a reaction promoter such as Pt. Different combinations of precisely size-selected, defect-rich TaOx and Pt nanoclusters are produced by a gas-phase aggregation technique in a special DC magnetron sputtering system. Argon flow rate and aggregation length are carefully optimized to control the sizes of these ultrasmall TaOx and Pt nanoclusters by using a quadrupole mass filter, and TEM studies reveal the different crystalline nature of TaOx (amorphous) and Pt (crystalline) nanoclusters. We have further demonstrated the size-dependent photoanode activity of (TaOx, Pt) nanocluster systems in a photoelectrochemical water splitting reaction, where the Pt nanocluster promoters are found to provide a significant enhancement in the photocurrent density, approximately tripled that was observed from just TaOx nanocluster catalysts alone. The photocurrent density and photoconversion efficiency tend to reduce when Pt nanoclusters become overpopulated due to blocking of the photosensitive TaOx surface. Reducing the Pt nanocluster size resolves this problem by incorporating a greater number of smaller nanocluster promoters without blocking TaOx, which leads to further enhancement in the photocurrent density. The enhanced photocatalytic activity is attributed to synergetic effects introduced by the Pt nanoclusters that act as temporary charge storage sites to facilitate effective separation of a large number of electron-hole pairs, generated from a large number of active sites on the defect-rich amorphous TaOx nanoclusters upon illumination.

Abstract
Gastroesophageal reflux disease (GERD) is defined as symptoms or complications associated with regurgitation from the stomach and/or the duodenum to the esophagus. Patients with type II diabetes mellitus (DM) were known to have higher prevalence of GERD in the Western countries, but data on the impact of GERD on DM patients in our country are scarce. The aim of this cross-sectional study was to evaluate the presence of GERD in type II DM patients admitted at the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2015 to September 2015. A total of 137 type II DM cases were purposively collected. Reflux Disease Questionnaire (RDQ) was used to check the presence of GERD. Patient's characteristics, laboratory data, face-to-face interview data were analyzed. Out of 137 type 2 DM patients 108 were suffering from GERD giving a prevalence rate of 78.8% which is quite high. Pathophysiological factors like age, sex, duration of DM, weight, waist circumference (WC) had no significant difference between GERD-DM and non-GERD-type II DM patients. Only hypertension and frequent eating fatty food were found to have significant differences between the two groups. From the study findings it could be said that the higher rate of GERD in patients with type II DM may be associated with lifestyle factor and some pathophysiological factors like hypertension. Psychiatric factors may also play role in contributing GERD. Further in-depth and large scale studies are necessary in our country in this regard.

Abstract
This cross sectional observational study was done in the Department of Medicine, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from May 2013 to April 2014 to find out the proportion of acute kidney injury among patients with acute viral hepatitis and to identify risk factors associated with development of acute kidney injury (AKI). A total of 100 patients with acute viral hepatitis were included purposively as study subjects. Among them 61 were male and 39 were female. They were divided into AKI group (n=6) and non-AKI group (n=94) on the basis of development of AKI. There was no significant difference in mean age (39.0±13.1 years vs. 32.2±10.8 years, p=0.335) and sex (67% vs. 61% & 33.0% vs. 39.0%) p=0.769) between AKI group and non-AKI group. There were 27% acute viral hepatitis A, 21% acute viral hepatitis B and 52% acute viral hepatitis E but no case of acute viral hepatitis C was found in this study. Acute kidney injury (AKI) developed in 6 of 27 patients with acute viral hepatitis A. This study showed that 22.2% patients with acute viral hepatitis A developed acute kidney injury but patients with acute viral hepatitis B (HBV) and hepatitis E (HEV) did not develop acute kidney injury. Majority of the patients with acute kidney injury were smokers and hypertensive with elevated mean arterial pressure (p=0.0001) at presentation and had higher total bilirubin (p=0.0001), alanine aminotranseferase values (p=0.040), prolonged prothrombin time (INR) {p=0.0001}, lower albumin (p=0.0001), lower haematocrit level (p=0.0001), high CRP concentration (p=0.0001), leucocytosis (p=0.0001) and thrombocytopenia (p=0.0001) at presentation than patients without acute kidney injury. It is evident from the study that acute kidney injury is not a rare complication in patients with acute viral hepatitis.

The main objective of the study was to determine the short term maternal outcome of pregnancy related Acute Kidney Injury and to identify aetiological factors and to observe clinical features of pregnancy related Acute Kidney Injury. Total 60 pregnant women with AKI were included in the study as sample and equal (60) number of pregnant women with normal renal function was taken as control. Mean ages (±SD) of study and control group were observed 31.6±6.9 years and 25.5±4.7 years respectively. It was observed that most patients were from rural area with low income group. Most women were multiparous and presented in third trimester and postpartum period. Majority of the study subjects did not receive antenatal care at any stage of pregnancy. Fifty (86.7%) of the study subjects were oligo-anuric, forty-nine (81.7%) were edematous and fifty one (85%) were anaemic. Twenty-five (41.7%) patients presented with abnormal vaginal bleeding. Sepsis (including septic abortion and puerperal sepsis) was responsible for of Pregnancy Related AKI (PR-AKI) in more than two fifths of cases. Haemorrhage (APH & PPH combined) was the next common cause of Pregnancy Related AKI (PR-AKI). Toxemia of Pregnancy was responsible in one fourth of cases. Dialysis (HD & IPD combined) was required for two fifths of the patients. Rest patients were treated conservatively with antibiotics, blood transfusion, maintenance of fluid and electrolytes balance etc. Maternal outcome of Pregnancy related acute kidney injury was considered for the period of patient's hospital staying. 56.6% patients recovered completely, 15.0% patients recovered partially, 6.7% did not recover at the time of hospital discharge; while 21.7% died. So it can be concluded that, pregnancy related acute kidney injury is a critical condition, associated with worse prognosis.

Abstract
Studies of the impact of mental disorders on educational attainment are rare. Mental disorders, those beginning in childhood or adolescence may increase the risk of early drop out from education. The latter has been shown to have adverse life-course consequences on individuals such as greater demand on social welfare entitlements. A descriptive cross sectional study was carried out at the department of Psychiatry, Comilla Medical College, Comilla, Bangladesh. All cases were selected from patients attending at Comilla Medical College Hospital and Private Mental Health Facilities in Comilla City from March 2015 to February 2016. We found out the psychiatric disorders and socio-demographic status of patients with educational drop out over the early life course. A total of 50 dropout patients aged 10 to 30 years who fullfiled the enrolment criteria included in the study. Sociodemographic questionnaires, diagnostic information (DSM-5 and ICD-10) as well as an account of a various level of education were used as research instruments. The Frequency tables, summary tables and appropriate graphs were prepared to describe the population characteristics and study finding. The most of the psychiatric morbidity presents in male (62%) and age group of 18-24 years (54%). In this study, anxiety disorders was 8%, behaviour/ impulse control disorders was 8%, mood disorders was 16%, substance use disorders was 24%, schizophrenia spectrum disorders was 12% and composite psychiatric disorders was 32%. Among drop out patient's non- completion of primary education was 14%, non-completion of secondary education was 20%, non- completion of higher secondary education was 24%, not entry to tertiary education was 12% and non-completion of tertiary education was 30%. Among behaviour/impulse control disorders non-completion of primary education was 6%, substance use disorders non-completion of higher secondary education was 10%, mood disorder both non-completion of higher secondary education and non-completion of tertiary education were 6%. Among composite psychiatric disorders non-completion of secondary education, non-completion of higher secondary education and non-completion of tertiary education were 8%, 6% and 12% respectively. Onset of mental disorders and subsequent drop out from education was found in this study. Further multi-centered prospective and population-based studies should be designed to find out the exact situation.

Abstract
Asthma is a public health problem that adversely affects different aspects of quality of life. Childhood asthma is common in Bangladesh affecting their lifestyle. The objective of the study was to assess health-related quality of life in children with bronchial asthma. A descriptive, cross-sectional study was carried out from January 2014 to December 2014 at the Outpatient Department of National Asthma Centre, Mohakhali, Dhaka among hundred sixty-two purposively selected children of both sexes with bronchial asthma aged from 7 to 17 years. Data were collected through interview with children or their parents using an interviewer-administered questionnaire based on Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Data were analyzed by computer software SPSS version 16.0. The mean age was 12.5 years with a standard deviation (SD) of 2.9 years. Overwhelming majority 157(96.9%) of children were literate, while only 5(3.1%) children were illiterate. Eighty (49.4%) children were male, while 82(50.6%) female. As many as 148(91.4%) children were students, while 10(6.2%) children were engaged in some type of job and 4(2.5%) children had no occupation. Parents of 145(89.5%) children were currently married, while 10(6.2%) children had single parent and 7(4.3%) children's parents were divorced or separated. Quality of life in children with asthma decreases with age as the disease intensity increases with age. Female asthmatic children had lower overall score of Quality of life (p=0.017), as well as lower activity domain score (p<0.001). Emotional domain score was found lower in children with single parent (p=0.021) and low monthly family income (p<0.001). Furthermore, children with lower monthly family income and working children had lower Quality of life score in all domains.

Abstract
Nasogastric intubation is a common procedure with both merits and demerits. Controversies exist about the routine use of nasogastric intubation following upper gastrointestinal surgery. Good numbers of literatures were published in favour of selective nasogastric intubation pointing out some complications of routine use of nasogastric tube. In 1995, Cheatham et al. concluded in a meta-analysis that although patients may develop abdominal distension or vomiting without a nasogastric tube, this is not associated with an increase in complications or length of hospital stay. For every patient requiring insertion of a nasogastric tube in the postoperative period, at least 20 patients will not require nasogastric decompression. In July 2004, Cochrane database of systemic review published the result of their systemic review on the prophylactic decompression after abdominal surgery, that review was revised and updated in 2007. According to this database, routine nasogastric intubation should be abandoned in favour of selective use of nasogastric tube. In our country some surgeons are practicing it routinely and some are not. This observation prompted us to conduct this study in order to see and compare the outcome of upper gastrointestinal surgery with and without nasogastric intubation. This will help us to make decision whether nasogastric intubation will be done routinely or not following upper gastrointestinal surgery.

Abstract
Background: Serum carbohydrate antigen 19-9 (CA 19-9), a tumour marker for malignancies of the hepatobiliary tract and pancreas, frequently elevated in a number of non-malignant conditions that are associated with jaundice. The CA 19-9 tends to normalize following the restoration of biliary drainage. This study was designed to assess the clinical application of CA19-9 in diagnosing pancreatobiliary malignancies in patients with obstructive jaundice and in discriminating between benign and malignant causes.Methods: Sixty three patients presented with obstructive jaundice on the basis of clinical, biochemical and imaging methods with elevated CA 19-9 were included in this study. Serum CA 19-9 levels were measured on admission and two weeks following endoscopic biliary drainage performed through an ERCP procedure at the department of Gastrointestinal, hepatobiliary and pancreatic disorders (GHPD) of BIRDEM general hospital. Malignant and benign cases were differentiated by ultrasonogram, CT scan, MRCP and morphological findings during ERCP procedure. Diagnostic accuracy of CA19-9 in the detection of malignancy was estimated by the receiver operating characteristic (ROC) curve.Results: Age was 53.76±14.48 years (mean±SD) and sex was 32:31 (M:F). Median value of CA 19-9 in malignant cases was higher (1000 U/ml) than benign cases (93 U/ml) (p=0.001). After biliary drainage serum CA19-9 levels normalized in 15(50%) benign and 1(3%) malignant cases (p=0.001). The AUC of CA 19-9 was 0.825. Sensitivity, specificity, PPV and NPV at cut off value 90 U/ml were 100, 50, 68.8 and 100; at 100 U/ml were 100, 53.3, 70.2 and 100; at 200 U/ml were 90.9, 66.7, 75 and 87, at 500 U/ml were 63.6, 76.7,75 and 65.7 respectively. Diagnostic accuracy of CA 19-9 was observed more at cut off value 200 U/ml.Conclusions: Deranged CA19-9 is frequently observed in benign conditions with jaundice and shown to normalize following improvement of biliary drainage. Caution is necessary in the interpretation of an elevated serum CA 19-9 value as a marker for malignancy, especially in patients with benign cholestasis.Birdem Med J 2017; 7(2): 95-100

Abstract
Our objective is to review the records of management of hepatoblastoma (HB) at the Paediatric Haematology and Oncology (PHO) department in the Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2004 to December 2012. This is a retrospective study of clinical, radiological and pathological data of hepatoblastoma patients treated at our institution. Thirteen patients were treated for HB between 2004 and 2012. The records of clinical presentations, chemotherapy tolerance and response, surgical procedure undertaken, and complications were analyzed. Median age of the study population was 12 months (3-60 months) and male: female was 3.3:1. Nine patients were treated with neoadjuvant chemotherapy consists of cisplatin and adriamycin. Primary surgery was done in four patients. Extent of hepatic resection in the operated patients varied. Mixed type was the predominant histopathological diagnosis. Adjuvant chemotherapy was well tolerated with no morbidity or mortality. Five-year event-free survival (EFS) and overall survival (OS) of all the 13 patients is 76.9%. All the nine patients who could complete multimodality treatment are alive with no evidence of disease or complications with median follow-up of 63 months (46-122 months). Treatment of HB with multidisciplinary approach was well tolerated. OS and EFS of patients were comparable with published studies.

Abstract
Wilson's disease (WD) is an autosomal recessive disorder affecting copper metabolism causing copper induced damage to various organs. In children liver is commonly involved. Central nervous system, eyes, RBC, kidneys, brain and bones may also be affected. Aim of the study is to evaluate clinical & laboratory profile of Wilson's disease in children. This cross sectional descriptive study was conducted at the department of Paediatric Gastroenterology and Nutrition, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from January 2011 to December, 2013. One hundred consecutive children of WD between 3 to 18 years of age were evaluated for clinical & biochemical profile. Mean age of studied children was 8.5±1.5 years. Male female ratio was 2:1. Ninety one percent patients were Muslim and nine percent Hindu. Consanguinity of marriage was found in 30% cases. Seven parents were first degree cousin. Family history of chronic liver disease was present in 15% of patients. Most (53%) cases of the hepatic WD presented between 5 to 10 years of age and most of the neurologic WD manifested in 10-15 years age group. Among 100 patients of WD, 69 children presented only with hepatic manifestations, 6 only with neurological manifestations, 14 with both hepatic & neurological manifestation, 10 children was asymptomatic and 1 patient presented with psychiatric features. WD presented as chronic liver disease (CLD) in 42%, CLD with portal hypertension in 34%, acute hepatitis in 20% and fulminant hepatic failure in 4% cases. Stigmata of chronic liver disease were found in 18% patients. Commonest stigmata was thenar and hypothenar wasting (n=8). Keiser- Fleischser ring (K-F ring) was found in 76% of the total patients. K-F ring was present in 84% ( 58 out of 69) of the hepatic only Wilsonian patients and in 90% (18 out of 20) of all neurologic Wilsonian patients. Asymptomatic and psychiatric patient had no K-F ring. About 26% of the WD patients had Coombs negative hemolytic anemia in PBF. Most of the WD patients had altered liver function. Elevated serum transaminase was found in 85% of all cases, prolonged prothrombin time in 59% cases & low serum albumin in 53% cases. Seventy three percent patients had low serum ceruloplasmin, basal urinary copper of >100μgm/day was found in 81% cases and urinary copper following penicillamine challenge of >1200μgm/day was found in 92% cases. In 28 cases with hepatic presentation esophageal varices were identified by upper gastrointestinal endoscopy. WD patient with hepatic presentations were given zinc sulphate along with penicillamine. All patients with neurological manifestation as well as asymptomatic cases were maintained on zinc therapy. WD is a treatable metabolic cause of liver disease. Majority of studied WD children presented with hepatic manifestation of which 76% presented with CLD. Any child presented with jaundice after the age of 3 years should be investigated for WD.

Abstract
Sustainable bioelastomers with high elastic recovery, high resilience and mendability are conceptualized with low chain-entanglement polymers that are predominantly originated from renewable biomass. Polymers with plant oil-derived fatty groups at the side chain were installed with furan, which allowed Diels-Alder addition to introduce dynamic covalent crosslinking. These elastomers are mendable via retro Diels-Alder. Reprocessing of these polymers led to the formation of elastomers with preservation of excellent resilience and elastic recovery.

Abstract
Infectious diseases caused by drug-resistant microorganisms have become a major contributor for human morbidity and mortality. To overcome such threats, we have developed various antimicrobial agents using natural product derivatives and metallopolymers. Abundant biomass such as resin acids can be utilized to prepare cationic polymers for inhibiting a variety of bacteria. These polymers have been used in solution as well as surfaces as antimicrobial materials with low cytotoxicity. In addition, a class of charged metallopolymers have been developed to kill superbugs such as MRSA.
