Abstract
BACKGROUND Around 1.5 billion people in the world are affected by complex neurological disorders, and the figure is increasing alarmingly due to unsatisfactory clinical outcomes. To date, no conventional formulation can show a promising effect on the control or prevention of neurodegeneration. However, Nano delivery tools have shown better penetration and profound action on the targeted area of the brain. METHODS Although existing Nano therapeutic approaches are abundant but would not reach the clinic due to their improper bioavailability, BBB restricts its entry and causes improper biodistribution, so it is a challenge to use certain bioactive as a potential therapy in neurodegenerative disorders. Hybrid nanocarriers are nano-vesicular transported systems which could be utilized as carriers for the delivery of both hydrophilic and hydrophobic compounds. Available patents on nanodelivery for therapeutic approaches will also include in this review. RESULTS Hybrid Nano delivery system may provide good stability to polar and nonpolar compounds and improve their stability. CONCLUSION This manuscript updates the available findings on the Nano vesicular system to deliver drugs for neurodegenerative disorders.

Abstract
Various abnormalities of coagulation such as primary hemostasis, secondary hemostasis and fibrinolysis have been reported in patients with subclinical and overt hypothyroidism. Platelets are major elements of primary hemostasis and endothelial repair. Platelet size, shape and number are the determinant of platelet function. The objective of this study was to assess primary hemostasis by PFA-100 (Platelet Function Analyzer-100) and its relation with TSH and FT₄ levels in newly diagnosed overt and subclinical hypothyroid patients. This cross-sectional study was conducted in the Department of Physiology, Dhaka Medical College, Bangladesh from January 2016 to December 2016. Twenty overt and 20 subclinical hypothyroid patients with age ranging from 18 to 55 years were selected as study group and twenty age and sex matched healthy subjects were considered as control group. Patients were selected from Outpatients Department of Endocrinology and Nuclear Medicine & Allied Sciences of Dhaka Medical College Hospital, Dhaka on the basis of exclusion and inclusion criteria. For assessment of primary hemostasis, PFA-100 was analyzed by SIEMENS-INNOVANCE-PFA-200. For statistical analysis Unpaired Student's 't' test, Chi square test and Pearson's correlation co-efficient (r) test were performed. PFA-100 was significantly higher (p<0.001) in overt and subclinical hypothyroid patients as compared to healthy adult subjects. In overt and subclinical hypothyroidism using PFA-100, we found that the existence of a hypocoagulable state is due to a defect in primary hemostasis. Moreover, PFA-100 may replace the in-vivo bleeding time as a screening test for primary hemostasis in routine clinical practice.

Abstract
Diabetic neuropathy (DN) is a common and debilitating complication of diabetes mellitus that affects the peripheral nerves and causes pain, numbness, and impaired function. The pathogenesis of DN involves multiple molecular mechanisms, such as oxidative stress, inflammation, and pathways of advanced glycation end products, polyol, hexosamine, and protein kinase C. Phytochemicals are natural compounds derived from plants that have various biological activities and therapeutic potential. Flavonoids, terpenes, alkaloids, stilbenes, and tannins are some of the phytochemicals that have been identified as having protective potential for diabetic neuropathy. These compounds can modulate various cellular pathways involved in the development and progression of neuropathy, including reducing oxidative stress and inflammation and promoting nerve growth and repair. In this review, the current evidence on the effects of phytochemicals on DN by focusing on five major classes, flavonoids, terpenes, alkaloids, stilbenes, and tannins, are summarized. This compilation also discusses the possible molecular targets of numerous pathways of DN that these phytochemicals modulate. These phytochemicals may offer a promising alternative or complementary approach to conventional drugs for DN management by modulating multiple pathological pathways and restoring nerve function.

Abstract
The novel corona virus (SARS CoV-2) was first detected on Wuhan, China. After that it spread worldwide and has caused many deaths till now. This virus is also known as novel corona virus because of being newly discovered. Scientifically it is named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has positive-single stranded RNA and several proteins such as spike (S), envelope (E), membrane (M), nucleocapsid (N) and the other helper proteins. On the basis of phylogenic evidence, it is the new member of beta corona viruses and this group of viruses causes respiratory illness in human. This virus is detected in laboratory by using RT-PCR, by which different target gene such as E gene, S gene, N gene and RdRP (ORF1a-ORF1b) etc. are detected. This study was carried out at Mymensingh Medical College from April 2020 to December 2020. Around 65000 samples (nasopharyngeal swab) were tested during this period by three PCR protocols. By Sansure PCR kit N and ORF1a target genes were detected, Basphore's target genes were E and ORF and by Neoplex PCR kit N and RdRp genes were detected. Most of samples were tested by Sansure kit (62500), 2000 samples were screened by Bosphore kit and 500 samples by Neoplex. Among them, 6876(11.0%) samples were positive by Sansure, 120(6.0%) by Bosphore and 66(13.2%) by Neoplex. Among the positive samples, N gene 6188(90.0%) was mostly found by Sansure kit, whereas ORF was 120(100.0%) mostly found by Bosphore.

Abstract
Neurodegeneration is characterized as the continuous functional and structural loss of neurons, resulting in various clinical and pathological manifestations and loss of functional anatomy. Medicinal plants have been oppressed from ancient years and are highly considered throughout the world as a rich source of therapeutic means for the prevention, treatment of various ailments. Plant-derived medicinal products are becoming popular in India and other nations. Further herbal therapies shows good impact on chronic long term illnesses including degenerative conditions of neurons and brain. The use of herbal medicines continues to expand rapidly across the world. The active phytochemical constituents of individual plants are sometimes insufficient to achieve the desirable therapeutic effects. Combining the multiple herbs in a particular ratio (polyherbalism) will give a better therapeutic effect and reduce toxicity. Herbal-based nanosystems are also being studied as a way to enhance the delivery and bioavailability of phytochemical compounds for the treatment of neurodegenerative diseases. This review mainly focuses on the importance of the herbal medicines, polyherbalism and herbal-based nanosystems and its clinical significance for neurodegenerative diseases.

Abstract
Globally, the emergence of multidrug-resistant strains of Mycobacterium tuberculosis is an increasing problem that adversely affects patient care and public health. This cross sectional descriptive study was carried out in the Department of Microbiology, Mymensingh Medical College from January 2010 to December 2010 to isolate M. tuberculosis from smear-positive sputum samples by Lowenstein-Jensen (L-J) media and investigate the drug resistance pattern. Among 101 smear-positive cases 80(79.20%) yielded growth of Mycobacteria, 5(4.95%) were contaminated and 16(15.84%) showed no growth. Among 80 isolates 76(95.0%) were M. tuberculosis and the remaining 4(5.0%) were Non-tuberculous Mycobacteria (NTM). Out of 76 M. tuberculosis 27(35.52%) were resistant to at least one drug, 4(5.26%) to Isoniazid (INH), 1(1.32%) to Rifampicin (RMP), 8(10.53%) to Streptomycin (SM) and 0(0.0%) to Ethambutol (EMB) and multi-drug resistant tuberculosis (MDR-TB) was 9(11.84%). The present study creates the impression that fairly high rate of anti-tuberculosis drug resistance among the tuberculosis cases and also high MDR-TB (Resistant to both Rifampicin and Isoniazide). The emergence of MDR-TB poses significant trouble to TB control activities throughout the world. The complexity of MDR-TB operation makes it essential to produce new skills to design, plan, application and monitor interventions for the management of MDR-TB. More surveillance and immediate remedial interventions should be performed to combat the trouble of MDR-TB to the general population.

Abstract
This study explored the structural, electrical, and magnetic properties of diamagnetic aluminium (Al3+) substituted nickel-zinc-cobalt (Ni–Zn–Co) mixed spinel ferrites, though the research on this area is in the infancy stage. Single-phase cubic spinel structures with the Fd3̄m space group of the synthesized Ni0.4Zn0.35Co0.25Fe(2−x)AlxO4 (0 ≤ x ≤ 0.12) ferrite samples were confirmed by X-ray diffraction (XRD) analysis. The average particle size ranged from 0.67 to 0.39 μm. Selected area electron diffraction (SAED) patterns were indexed according to the space group Fd3m, representing the particle's crystallinity. The optical band gaps ranged from 4.784 eV to 4.766 eV. Frequency-dependent dielectric constants and ac conductivity measurement suggested that the prepared ferrites were highly resistive. Relaxation times were reduced to a low value from 45.45 μs to 1.54 μs with the composition x. The Curie temperatures (Tc) were 615–623 K for all samples. Real part permeabilities (μ/) were relatively stable up to an extended frequency range of 106 Hz with relative quality factors (RQF) of around 103. Tuning of the properties indicates that the fabricated ferrites may be promising for high-frequency electronic devices. This study explored the structural, electrical, and magnetic properties of diamagnetic aluminium (Al3+) substituted nickel–zinc–cobalt (Ni–Zn–Co) mixed spinel ferrites, though the research on this area is in the infancy stage.![]()

Abstract
In Ayurvedic system of medicine, a variety of medicinal herbs are being prescribed for brain disorders, including mental dysfunction, indifference, and memory impairment. Neuropharmacological mechanisms of these herbs are poorly understood. A total of nineteen indigenous medicinal herbs of Bangladesh were investigated for their neuropharmacological potentials, including antioxidant, anticholinesterase, and neurotrophic activities. The antioxidant activity of plant ethanolic extracts was determined based on their DPPH free radical scavenging capacity. Acetylcholinesterase (AChE) inhibitory activity was determined by the colorimetric assay based on Ellman’s method. The neurotrophic activity of plant extracts was measured based on their capacity to promote neurite outgrowth in a primary culture of hippocampal neurons. Of the herbs, Camellia sinensis, Terminalia chebula, Cinnamomum tamala, Terminalia bellirica, Phyllanthus emblica, and Curcuma longa exhibited remarkable antioxidant activity with IC50 values of <100 µg/mL. The highest anticholinesterase activity was shown by C. longa (IC50 9.37 µg/mL) followed by C. sinensis (IC50 86.01 µg/mL) and C. tamala (IC50 86.37 µg/mL). Notably, C. tamala showed the highest neurotrophic activity (an increase in the length of primary neurites by 82% compared to control), whereas C. sinensis and C. longa showed moderate activities. The neurotrophic activity of C. tamala was reported for the first time. The present findings indicate that these indigenous herbs, particularly C. tamala, C. sinensis, and C. longa possess a remarkable neuropharmacological potential and suggest that these neuroactive herbs could be used in disease-modifying therapies for brain disorders.

Abstract
Enteric fever is a common bacterial infection in the tropics and endemic to Bangladesh. The volatile manifestations of enteric fever construct this disease a true diagnostic confrontation. There are limited current objective data on the value of individual clinical features of enteric fever in the diagnosis of enteric fever. The aim of the study was analysis of clinical features and also proposed a clinical diagnostic criterion of enteric fever among adult in Bangladesh. This cross-sectional comparative study was performed among which of fifty confirmed enteric fever and hundred non enteric febrile adult patients in Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2015 to December 2015. Purposive sampling technique was implied for convenience of the study. In this study, history of step ladder fever, diarrhoea and relative bradycardia, ceacal gurgle, abdominal distension were proved to be powerful markers of enteric fever with high specificity (100.0%, 90.0%, 95.0%, 92.0% and 95.0% respectively). Tender right iliac fossa (RIF) and coated tongue, hepatomegaly were moderately powerful with 86.0%, 88.0%, 89.0% specificity respectively. Positive predictive value (PPV) was highest for step ladder fever (100%) and negative predictive value (NPV) was highest for headache (92.5%). Highest sensitivity, PPV and NPV were found for relative bradycardia and tender RIF but most of the signs had good specificity. Regarding accuracy it was highest for step ladder fever (91.3%), relative bradycardia (94%), tender RIF (87%), coated tongue (82%) and splenomegaly (84%). Therefore, a clinical diagnostic criterion was submitted with diagnostic accuracy more than 70% were taken into deliberation. The Major criteria were considered step ladder fever, relative bradycardia, tender RIF with diagnostic accuracy 91.0%, 94.0% and 87.0% respectively. Minor criteria included splenomegaly, diarrhoea, coated tongue, ceacal gurgle, chills with diagnostic accuracy 85.0%, 85.0%, 82.0%, 76.0%, 72.0% respectively and after amalgamation of various major and minor criteria a final diagnostic criterion was submitted having accuracy more than 60.0%. In conclusion the clinical profile of enteric fever in culture proven patients with a view to highlight the predictive value of those features which would help general practitioners in the diagnosis and empiric treatment.

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

Abstract
Abstract
Background
Management of traumatic bone void associated with Gustilo IIIB open fractures is challenging. Gentamicin eluting synthetic bone graft substitute (Cerament-G) had been recently utilised for the management of patients with these injuries. This study aims to assess radiological signs of Cerament-G remodelling.
Method
Retrospective data analysis of all patients admitted to our unit with IIIB open fractures who had Cerament-G applied as avoid filler. Postoperative radiographic images of the fracture site at 6-weeks, 3-months, 6-months and at the last follow-up were reviewed. The radiological signs of Cerament-G integration, percent of void healing, and bone cortical thickness at the final follow-up were assessed.
Results
34 patients met our inclusion criteria, mean age: 42 years. Mean follow-up time was 20 months. 59% of patients had excellent (>90%) void filling, 26.4% of patients had 50-90% void filling, and 14.6% had < 50% void filling. Normal bone cortical thickness was restored on AP and Lateral views in 55.8% of patients. No residual Cerement-G was seen on X-rays at the final follow-up in any of the patients.
Conclusions
Our results showed successful integration of Cerament-G with excellent void filling and normal cortical thickness achieved in more than half of the patients.

Abstract
Incidence of Myocardial Infarction is increasing day by day in developing countries. Most of the patients who sustain myocardial infarction have coronary atherosclerosis. There are several risk factors for the development of atherosclerosis. Among all the risk factors, vitamin D deficiency has been proposed to play an important role in the development of atherosclerosis. With this aim, a case-control study was carried out to explore the association of serum vitamin D with acute myocardial infarction. The enrolled study subjects were categorized into Group A which comprised of STEMI, Group B, comprised of NSTEMI and Group C comprised of age and sex matched individuals free from acute myocardial infarction. The mean values of serum vitamin D (in ng/ml) were 20.17, 20.8 and 24.77 respectively in STEMI, NSTEMI and control groups. It differed significantly among groups (p<0.001) and it was significantly low in STEMI and NSTEMI groups compared to control group (p<0.001 and p=0.004). From this study it can be concluded that low serum vitamin D is an independent risk factor for developing acute myocardial infarction. Individuals with serum vitamin D <20ng/ml have higher chance of developing acute myocardial infarction compared to those with serum vitamin D >20ng/ml.

Abstract
Hemoprotozoans are important pathogens of animals and humans, among which some species have zoonotic significance. The prevalence of different hemoprotozoa and Anaplasma spp. in larger mammals have been reported from different regions of the world. But, very few studies have been conducted to estimate the prevalence of hemoprotozoa in rodents and shrews of South-East Asia. The study assessed the prevalence of hemoprotozoa and Anaplasma spp. in rodents and shrews of Bangladesh. Blood samples (n=451) were collected from rodents and shrews between June 2011 and June 2013 and July-December 2015 from 4 land gradients of Bangladesh. Giemsa-stained blood smears revealed that 13% of animals were harboring hemoprotozoa (4.7% Babesia spp., 0.67% Plasmodium spp.), and Anaplasma spp. (7.5%). The study may serve as a guide for future hemoparasitic research of rodents and shrews.

Abstract
The Coronavirus disease 2019 (COVID-19) resulted severe respiratory illness such as pneumonia and lung dysfunctions that was first identified at Wuhan, the capital of Hubeiin China during the end of December 2019. The etiological cause of COVID-19 has been confirmed as a novel coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which was similar with the zoonotic virus SARS-CoV (2002). Now a days for early diagnosis of COVID-19 the nucleic acid based test like RT PCR (real time reverse transcription polymerase chain reaction) is most consistent and used all over the world. In this study among 11,280 cases 825(7.31%) were positive by molecular RT PCR method on June 2020 at Microbiology department of Mymensingh Medical College and the samples are collected from different areas of Northern part of Bangladesh. Among this positive cases 588(71%) N gene, 10 ORF1ab (2%) and 227(27%) both N and ORF gene showed significant curve which is specific for COVID-19 positive patients. Because N and ORF gene of this virus inhibit immune system of human body especially interferon. Out of SARS-CoV-2 positive cases maximum number of N gene were found in male patients and above 40 years old aged group. So, Molecular diagnosis of this pandemic virus especially by N and ORF gene might be helpful to reduce the spread of SARS-CoV-2 as well as early treatment for saving many lives.

Abstract
The prevalence of Helicobacter pylori (HP) infection is very high in Bangladesh. Chronic gastritis due to H. pylori is commonly associated with important gastric diseases such as peptic ulcer diseases or gastric carcinoma and MALT-oma. The natural course of chronic gastritis is HP-associated antral gastritis or pangastritis or rarely atrophies. This study was done to see the association of H. pylori genotypes with chronic gastritis. This observational cross sectional study was carried out at Bangabandhu Sheikh Mujib Medical University from July 2012 to April 2013 to find out the association of H. pylori genotypes with chronic gastritis in dyspeptic patients of Bangladesh. A total of 50 dyspeptic subjects were involved in the study whose upper GI endoscopies were carried out in presence of an experienced endoscopist. During the procedure four biopsies were taken, two from the antrum and two from body of the stomach. Endoscopic diagnosis was categorized into normal and erosive gastritis. Two (one from antrum and one from body) biopsy samples were collected in phosphate buffer saline and PCR analysis carried out by Multiplex PCR assay. Another two were collected in 10% formalin and histopathological examination was done according to updated Sydney system of classification. Among 50 patents only 34 were PCR positive. So, only 34 subjects were included in the study. Among them 21 patients (61.8%) were male and 13 patients (38.2%) were female, with the mean age of 29.91 years. Endoscopy revealed erosive gastritis in 5(14.7%) patients and normal findings in 29(86.3%) patients. Amongst the strains, cagA gene was detected in 58.8% and was not significantly associated with severity of any parameter of chronic gastritis such as H. pylori density, inflammation (mononuclear infiltration), activity (neutrophilic infiltration), atrophy and intestinal metaplasia. All the strains were positive for vacA allele. s1m1 (55.9%) genotype was most predominant. No vacA allele (s1m1, s1m2, s2m1 and s2m2) were significantly associated with severity of chronic gastritis. In this study, H. pylori genotype -cagA, vacA-s1, s2, m1, m2 allele and histological grading of chronic gastritis according to updated Sydney system of classification is identified. This study will identify the genotypes associated with severe gastritis in our country and thereby help us to take appropriate preventive measure. Further study with larger sample size may be carried out to establish proper association between different genotypes and parameters of chronic gastritis.

Abstract
The coronavirus disease (COVID-19) is highly pathogenic viral infection caused by SARS-CoV-2. Currently, COVID-19 has caused global health concern. WHO has declared COVID-19 as a pandemic disease on March 11, 2020 and characterized by fever, dry cough, fatigue, myalgia and chest pain with pneumonia in severe cases. The virus has spread to at least 213 countries and more than 9093827 confirmed cases and 471490 deaths have been recorded. In the beginning, the world public health authorities tried to eradicate the disease in China through quarantine but are now transitioning to prevention strategies worldwide to delay its spread. There are some newly developed and promising methods for detection of SARS-CoV-2, in order to facilitate the development of novel approaches for early diagnosis. Nucleic acid based tests currently offer the most sensitive and early detection and confirmation for SARS-CoV-2 infection. Among them Real-time reverse transcription polymerase chain reaction (rRT-PCR) is the most popular and the "gold standard" testing method for the detection of SARS-CoV-2. The present study was carried out to detect 2019-Novel Coronavirus (2019-nCoV) by rRT-PCR method at Mymensingh Medical College, Mymensingh, Bangladesh from 1st April, 2020 to 31st May, 2020. A total of 14356 samples were tested from four districts of Mymensingh division namely, Mymensingh, Jamalpur, Sherpur, Netrokona and some parts of Sunamganj for rRT-PCR. Among them 1086 (7.5%) patients were positive for SARS-CoV-2. Out of 1086 positive cases 716(65.9%) were male and 370(34.1%) were female with a Mean±SD age 34.1±12 years. Maximum positivity was found in Mymensingh district followed by Netrokona, Jamalpur, Sherpur and Sunamganj respectively. This is the first base line study for genetic detection of 2019-nCoV in Mymensingh division which may reflect the total scenario of Bangladesh situation. We hope this paper will help the researcher to increase the availability, accuracy, and speed of widespread COVID-19 testing throughout the world in this crisis moment.

Abstract
Anterior resection (AR), especially low anterior resection (LAR), for low rectal cancer and colorectal anastomosis is a technical challenge to surgeons. But by using circular stapling devices now it is possible make more LARs technically feasible. A stapled end-to-end colorectal anastomosis is increasingly adopted following a low anterior resection for low rectal cancer. This descriptive cross-sectional study was carried out in the department of Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from December 2015 to December 2016. The ensuing doughnuts created from the stapling device are routinely sent for histological analysis. However, its efficacy remains debatable. This study aims to determine the role of sending distal doughnut for histological examination following a stapled end-to-end colorectal anastomosis done in low anterior resection for low rectal cancers.

Abstract
Hyperparathyroidism may be a precipitating factor to the development of myelofibrosis; however, this is extremely rare with only a few documented case reports of myelofibrosis caused by secondary hyperparathyroidism. We describe a case of a 24-year-old female who had a failed live donor renal transplant and secondary hyperparathyroidism. While on haemodialysis she became increasingly pancytopenic despite erythropoietin injections and adequate iron, vitamin B12 and folate replacement. Her secondary hyperparathyroidism evolved to tertiary hyperparathyroidism despite vitamin D supplementation and phosphate binders. In order to determine the cause of her pancytopenia, a bone marrow biopsy was performed that confirmed myelofibrosis due to her secondary hyperparathyroidism. Following a successful parathyroidectomy in a tertiary hospital, her pancytopenia resolved and she is now awaiting a second transplant.

Abstract
Tuberculosis is a common cause of death in developing countries like Bangladesh. About 30% of pulmonary tubercular infected patients developed tubercular pleural effusion. Tubercular pleural effusion was diagnosed by cytological, biochemical and bacteriological methods. But these methods showed low sensitivity. In some cases pleural biopsy showed also negative results. Now a days molecular technique like Polymerase chain reaction (PCR) is promising method for diagnosis of pleural TB. PCR was done in 100 pleural fluid collected from suspected tubercular pleural effusion cases admitted in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2011 to January 2013. Among the 100 samples 3% were culture positive and PCR positive was 6%. Sensitivity and Specificity of PCR considering culture as a gold standard method was 100% and 96.71% respectively in this cross sectional study. Among them Adenosine deaminase (ADA) level is >40IU/L in all PCR positive sample. Where PCR is available, measurement of ADA activity as well as PCR can be done simultaneously.

Abstract
Purpose We develop an Active Shape Model (ASM) framework for automated bone segmentation and anatomical landmark localization in weight-bearing Cone-Beam CT (CBCT). To achieve a robust shape model fit in narrow joint spaces of the foot (0.5 - 1 mm), a new approach for incorporating proximity constraints in ASM (coupled ASM, cASM) is proposed. Methods In cASM, shape models of multiple adjacent foot bones are jointly fit to the CBCT volume. This coupling enables checking for proximity between the evolving shapes to avoid situations where a conventional single-bone ASM might erroneously fit to articular surfaces of neighbouring bones. We used 21 extremity CBCT scans of the weight-bearing foot to compare segmentation and landmark localization accuracy of ASM and cASM in leave-one-out validation. Each scan was used as a test image once; shape models of calcaneus, talus, navicular, and cuboid were built from manual surface segmentations of the remaining 20 scans. The models were augmented with seven anatomical landmarks used for common measurements of foot alignment. The landmarks were identified in the original CBCT volumes and mapped onto mean bone shape surfaces. ASM and cASM were run for 100 iterations, and the number of principal shape components was increased every 10 iterations. Automated landmark localization was achieved by applying known point correspondences between landmark vertices on the mean shape and vertices of the final active shape segmentation of the test image. Results Root Mean Squared (RMS) error of bone surface segmentation improved from 3.6 mm with conventional ASM to 2.7 mm with cASM. Furthermore, cASM achieved convergence (no change in RMS error with iteration) after ~40 iterations of shape fitting, compared to ~60 iterations for ASM. Distance error in landmark localization was 25% to 55% lower (depending on the landmark) with cASM than with ASM. The importance of using a coupled model is underscored by the finding that cASM detected and corrected collisions between evolving shapes in 50% to 80% (depending on the bone) of shape model fits. Conclusion The proposed cASM framework improves accuracy of shape model fits, especially in complexes of tightly interlocking, articulated joints. The approach enables automated anatomical analysis in volumetric imaging of the foot and ankle, where narrow joint spaces challenge conventional shape models.

Abstract
In world wide cervical cancer is the fourth most common among women, with the majority of cases occurring in developing countries. Some HPV infections persist, and a subset of persistent infections may lead to development of cervical intraepithelial neoplasia (CIN) or invasive cancer. Because neoplastic change typically takes some years to occur and it depends on multiple factors among them age and parity play important role. The objective of the cross sectional observational study was detection of oncoprotein depending on age and parity by immunochromatographic test (OncoE6 cervical test). Informed consent was taken from patients and the protocol was approved by IRB, Mymensingh Medical College, Mymensingh, Bangladesh. From April 2016 to March 2017 following universal safety precautions a total of 280 endocervical swabs were collected from VIA outdoor and Colposcopy clinic of Obstetrics and Gynaecology department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Laboratory work was done in the department of Microbiology, Mymensingh Medical College. The E6 strip test is an immunochromatographic test based on the detection of HPV-E6 oncoprotein in cervical swab samples. In this study VIA and OncoE6 cervical test were done on 280 cases and among them 120 were VIA positive and sent for colposcopy. From 120 VIA positive cases 70 were positive for colposcopy test. Afterwards 50 cases were selected for histopathological examination and classified into different grades. The present study showed 21(7.5%) cases were OnE6 cervical test positive by OncoE6 cervical test and most of them were found in advance aged <50 (38.09%) and multi parity (women more than two, 32.5%). Based on the findings of the present study, it may be concluded that age and multi parity plays important factor to cause cervical cancer. Now for prevention of cervical cancer we need screening which is an early detection tool. This is a low cost device, easily performed which can detect this HRHPV (High Risk HPV) and it will be helpful to reduce over treatment and high predictability of the disease.

Abstract
Giant-cell tumor constitutes 4-20% of all primary bone tumors in south East Asian population. They are benign locally aggressive bone tumour first described by cooper in 1818. These tumors occur predominantly in meta-epiphyseal region. Most often they are located around the knee joint. Although most of the tumors are diagnosed on plain radiograph alone, varying CT and MRI presentations of these tumors are essential to narrow down the differentials has an extended pre operative assessment.

Abstract
Mesenchymal stromal cells (MSCs), given their regenerative potential, are being investigated as a potential therapeutic tool for cartilage lesions. MSCs express several bioactive molecules which act in a paracrine fashion to modulate the tissue microenvironment. Yet, little is known about the divergence of these signalling molecules in different MSC populations. The present study investigated secretomes of stromal cells harvested from Hoffa's fat pad (HFPSCs), synovial membrane (SMSCs), umbilical cord (UCSCs) and cartilage (ACs) by quantitative liquid chromatography-mass spectrometry (LC-MS/MS) proteomics. Also, multiplex protein arrays and functional assays were performed to compare the constitutive immunomodulatory capabilities of different MSCs. Proteins involved in extracellular matrix degradation and inflammation, such as matrix metalloproteinases (MMPs), interleukin (IL)-17 and complement factors, were downregulated in UCSCs as compared to adult cell sources. Additionally, secretion of transforming growth factor (TGF)-β1 and prostaglandin E2 (PGE2) was enhanced in UCSC supernatants. UCSCs were superior in inhibiting peripheral blood mononuclear cell (PBMC) proliferation, migration and cytokine secretion as compared to adult stromal cells. SMSCs significantly suppressed the proliferation of PBMCs only if they were primed with pro-inflammatory cytokines. Although all cell types repressed human leukocyte antigen-DR isotype (HLA-DR) surface expression and cytokine release by activated macrophages, only UCSCs significantly blocked IL-6 and IL-12 production. Furthermore, UCSCs supernatants increased aggrecan gene expression in two-dimensional chondrocyte cultures. The data demonstrated that UCSCs displayed superior anti-inflammatory and immunosuppressive properties than stromal cells from adult tissues. This allogeneic cell source could potentially be considered as an adjuvant therapy for articular cartilage repair.

Abstract
Background: World Child Cancer (WCC) has been working in partnership with pediatric oncology programs in low-middle income countries (LMICs) to support improved services for children with cancer. Central to the success of services is the development of effective shared-care networks situated to match population centers. Literature on how to develop shared-care networks in LMICs does not currently exist. Aim: Modeling sustainable national, regional and local health systems based on childhood cancer shared-care networks in LMICs. Methods: The model was developed through learning from a 3 year UK Government (DFID) funded program in Ghana and Bangladesh and lessons shared from WCC-funded programs in Myanmar and the Philippines. A workshop was held focusing on lessons learned from practitioners representing shared-care networks in different stages of development to identify key elements and steps necessary to build a shared-care network. Results: The overarching themes of the model are; good communication, health partnerships (twinning) and funding. A successful shared-care network must have a strong hub hospital at its center which requires a doctor with training and some experience in pediatric oncology, a committed multidisciplinary team, dedicated bed space, provision for training, patient data accurately recorded, essential medicines available and research opportunities accessible. A health partnership with an external developed center is beneficial. A tangible plan, developed treatment guidelines and protocols, measurable outcomes and financial support are needed for development into a center of excellence. Support would ideally be available for patients and families, to include accommodation, treatment costs, food and transport. Each shared-care center needs an interested doctor, a basic multidisciplinary team, some ward space for oncology patients and the support of the hospital administration. Patient data needs to be stored and there must be a close relationship with the hub center. A development plan is outlined and services provided should replicate the hub as well as resources allow. Major challenges include obtaining support from the hospital administration, and even more importantly, government policies and financing for such developments. Collaborative working and good communication are emphasized by using the same treatment protocols, developing two-way referral systems and sharing challenges and successes. The overarching principle of sustainability requires availability of training within the system and funding. Conclusion: This model can be shared to enable others in LMICs to access the information and inform their systems development. While the model is not exhaustive and requires further research, it represents an important first step with lessons learned from practitioners with experience. The inclusion of such practitioners in the process of developing this model is essential for sustainability.

Abstract
Acute leukemias are the most common child hood malignancy, of which acute myeloid leukemia (AML) are 15 to 20%. Abandonment is one of the most important causes of treatment failure in AML in developing countries. Lost to follow-up is also a big problem in low income countries. Many patients stop therapy soon after diagnosis due to cost, distance and ignorance. To determine the abandonment, outcome and treatment related mortality (TRM) and morbidity among children with AML. This prospective observational study was conducted in the Department of Pediatric hematology and Oncology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from February 2013 to January 2014. Fifty (50) patients of AML visited to out patient department (OPD) of Pediatric hematology and Oncology. Among them 11(22%) patients refuse treatment from outdoor. Thirty nine (78%) patients of AML were selected as per inclusion and exclusion criteria. After proper evaluation and clinical examination of these patients, CBC and Bone marrow examination was done for confirmation of diagnosis. A total of 39 patients were recruited in this study. Seventeen (43.6%) patients were male and 22(56.4%) were female. Mean±SD of age was 7.80±4.42 years and range was 1 year to 18 years. Out of 39 patients, 18(46.1%) patients were abandoned, 15(38.4%) expire, relapse 2(5.2%) & alive 4(10.3%). High abandonment (46.1%) and treatment related toxic death (38.4%) has compromised the outcome of acute myeloid leukemia. However AML can be treated with better outcome if improved the supportive care, reduce toxic death, refusal or abandonment.

Abstract
Acute lymphoblastic leukemia is the most common (77%) childhood leukemia and also the most common neoplastic disease in children. Acute lymphoblastic leukemia initially present with hyperleukocytosis (WBC count more than 50,000/mm³) in twenty percent cases. These children are particularly at risk of development of tumor lysis syndrome (TLS). Tumor lysis syndrome is a metabolic disorder consists of hyperuricaemia, hyperkalemia, hyperphosphataemia, hypocalcaemia with or without renal insufficiency. It is the most common disease related emergency encountered by physicians caring for cancer of children and adult. This cross sectional observational study was conducted in Department of Paediatric Haemato-oncology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from November 2011 to April 2012 and was designed to assess early biochemical changes associated with hyperleukocytosis which may follow tumor lysis syndrome. Children with Acute lymphoblastic leukemia with hyperleukocytosis who are potential to develop tumor lysis syndrome were selected for the study in their initial presentation. Thirty patients with newly diagnosed acute lymphoblastic leukemia with initial high WBC count; more than 50,000/mm³ were selected for the study. The objectives of the study were to observe the development of tumor lysis syndrome with hyperleukocytosis, detection of early signs of electrolyte changes and early detection of tumor lysis syndrome which can help further in the management of such patients. Majority of the cases were in age group 7 years to 15 years with male predominance (83%). Hyperphosphataemia (80%) followed by hyperuricaemia (53%) were the most common biochemical findings. Hyperkalemia and hypocalcaemia were present in 33% and 26% patients. Laboratory tumor lysis syndrome was developed in 40% of patients and clinical tumor lysis syndrome was developed in 20% patients with hyperleucocytosis meeting the criteria for definition of tumor lysis syndrome by Cairo Bishop in 2004. It was observed that TLS increased with higher WBC. Tumor lysis syndrome developed in 26% patients with WBC count below one lac, 50% with WBC count 1 lac to 2 lacs and increasing upto 100% with WBC count more than 3 lacs. Developing tumor lysis syndrome in high LDH (44% when LDH is more than 1000 unit/l) was also observed.
